Further, the processor 240 may identify weight estimation information of the laundry when receiving a washing program, receiving an operation start command, receiving option selection information, or receiving a power-on command.

The processor 240 may identify a stop period of the washing machine based on receiving the washing program. When recognizing that the recognized stop period is the predetermined period or more, the processor 240 may recognize the largest laundry weight among the laundry weights detected last, and recognize the set time corresponding to the recognized laundry weight and the received washing course, and allow the recognized set time to be displayed as the default time.

Upon receiving the washing program, the processor 240 may recognize whether the current date is a holiday. When recognizing that the current date is holiday, the processor 240 may recognize the laundry weight on weekend or recognize the largest laundry weight among the laundry weights detected in the past, recognize the set time corresponding to the recognized laundry weight and the received washing course, and allow the recognized set time to be displayed as the default time.

Upon receiving the operation start command, the processor 240 recognizes the laundry weight corresponding to the detection information of the detector 230, recognizes the set time corresponding to the laundry weight and the received washing course, and allows the recognized set time to be displayed on the display as the actual operation time.

That is, after detecting the weight of the laundry, the processor 240 controls the operation of the display 220 such that the display 220 changes the default time displayed on the display 220 to the actual operation time and displays the actual operation time.

The processor 240 may allow a washing time change notification to be output on the display 220 or through a speaker (not shown). The washing time change notification represents a notification indicating a change from the default time to the operation time.

The processor 240 updates the information stored in the storage device 250 by storing the actual operation time corresponding to the received washing course and the detected weight of the laundry in the storage device 250 as a default time.

The actual operation time may be a set time corresponding to the received washing course and the detected weight of the laundry, or may be an operation time taken when the washing machine is actually operated in the received washing course based on the set time.

That is, the set time and the operation time corresponding to the received washing course and the detected weight of the laundry may be identical to each other, or may have an error time of a predetermined size or less.

When the actual operating time is stored as the default time in the storage device 250, the processor 240 identifies information having the same condition as the received washing course and weight estimation information among the information stored in the storage device 250, and further stores the obtained actual operating time as the default time in the identified information.

Further, when the actual operating time is stored as the default time in the storage device 250, the processor 240 may identify the default time having information which has the same condition as the received washing course and weight estimation information among the information stored in the storage device 250, and calculate an average time of the identified default time and the obtained actual operating time, and store the calculated average time as a new default time.

Further, when the actual operating time is stored as the default time in the storage device 250, the processor 240 may identify the laundry weight corresponding to the information having the same condition as the received washing course and the weight estimation information among the information stored in the storage device 250, and calculate an average weight of the identified laundry weight and the detected laundry weight, and store the calculated average weight together with the average time.

The information having the same condition is information having the same weight estimation information of the washing course and the laundry as the received weight estimation information of the washing course and the identified laundry among the information stored in the storage device 250.

The processor 240 may identify the laundry weight corresponding to the information having the same condition as the received washing course and weight estimation information, calculate the average weight of the identified laundry weight and the detected laundry weight, identify a weight class corresponding to the calculated average weight of the laundry, identify a set time corresponding to the identified weight class, and store the identified set time as a default time.

For example, when it is assumed that the weight of the laundry for the first monday's normal washing is 0.5kg, the weight of the laundry for the second monday's normal washing is 0.6kg, the weight of the laundry for the third monday's normal washing is 1.3kg, the weight of the laundry for the fourth monday's normal washing is 0.7kg, and the weight of the laundry for the fifth monday's normal washing is 0.4kg, the processor 240 obtains the average weight of 0.7kg five times (as a predetermined number of times), and calculates a level 1 corresponding to the obtained average weight, and stores the set time "a" corresponding to the level 1 as a default time.

Accordingly, when the washing machine is operated later under the same washing course and weight estimation information, the processor 240 may allow the currently obtained actual operation time to be displayed as a default time.

When the set time corresponding to the received washing course and the detected weight of the laundry is displayed as the operation time, the processor 240 may identify a weight level corresponding to the weight of the laundry, identify the set time corresponding to the identified weight level and the washing course, and allow the identified set time to be displayed as the actual operation time. The operation time displayed on the display may be a remaining operation time of the washing machine.

The processor 240 re-identifies the laundry weight corresponding to the detection information detected by the detector 230 during the execution of the washing program. When it is recognized that the re-recognized weight of the laundry is different from the weight of the laundry detected at the time of detecting the weight, the processor 240 obtains the remaining time based on the received remaining cycle in the washing course and the re-recognized weight of the laundry and allows the display to display the obtained remaining time.

The processor 240 may re-identify the laundry weight before performing at least one of the washing cycle, the rinsing cycle, the dehydrating cycle, and the drying cycle, or after completion of at least one of the washing cycle, the rinsing cycle, the dehydrating cycle, and the drying cycle.

When receiving the operation start command, the processor 240 may control the operations of the water supply 160, the heating part 190, the drain 180, and the blower (not shown) based on the received washing course and at least one option, so as to perform a washing cycle, a rinsing cycle, a dehydrating cycle, and a drying cycle corresponding to the selected washing course and the at least one option.

The processor 240 controls the operation of the display 220 to display the washing course selected by the user and at least one option.

Specifically, during the execution of the washing program, the processor 240 identifies the weight of the laundry corresponding to the detection information detected by the detector 230, and controls the washing cycle and the rinsing cycle by adjusting the amount of water based on the identified weight of the laundry and the washing program selected by the user, and controls the dehydrating cycle based on the identified weight of the laundry and the washing program.

When the washing course selected by the user includes the drying cycle, the processor 240 may control the drying cycle based on the weight of the laundry.

The processor 240 controls the operations of the water supply 160, the motor 150, and the drain 180 during the washing cycle and the rinsing cycle, and further controls the operation of the heating part 190 based on the selected water temperature. The processor 240 controls the operation of the motor 150 and the drainer 180 during the dehydration cycle, and the processor 240 controls the operation of the motor 150, the heating section 190 and the blower (not shown) during the drying cycle.

The storage device 250 may store a set time for each washing course corresponding to the weight of the laundry.

The storage device 250 may store a plurality of weight levels corresponding to a plurality of weight ranges of the laundry, and store a set time of each washing course corresponding to each weight level. The set time of each washing course corresponding to each weight class may be stored as a look-up table.

As shown in fig. 6, the storage device 250 may store the set time for each weight class of the general washing process. Among the set times, "a" may be the shortest time, and "e" may be the longest time. The length of time may be a < b < c < d < e.

The weight of the laundry may be stored as a weight grade corresponding to each weight range.

For example, a laundry weight in the range of 0 to 1kg may be stored as weight class 1, a laundry weight in the range of 1.1 to 2kg may be stored as weight class 2, a laundry weight in the range of 2.1 to 3kg may be stored as weight class 3, a laundry weight in the range of 3.1 to 4kg may be stored as weight class 4, and a laundry weight in the range of 4.1 to 5kg may be stored as weight class 5. The weight grade corresponding to the laundry weight range is only an example, and thus it may be different depending on the type, model and manufacturer of the laundry treating apparatus.

The storage device 250 stores a default time corresponding to at least one washing course selected by the user and the weight estimation information of the laundry.

The default time corresponding to at least one of the washing courses and the weight estimation information of the laundry may be operation information of the washing machine previously operated in the washing course selected by the user, and may be an actual operation time of the washing machine operated according to the weight of the laundry put into the drum and the washing course selected by the user.

In addition, the driver 270 may include a power switch circuit configured to allow or prevent current flow to the motor 150 in response to an on/off command by the processor 240.

Fig. 10 is a flowchart of a laundry treating apparatus according to an embodiment of the present disclosure, which will be described with reference to fig. 6 to 9.

The washing machine corresponding to the laundry treating apparatus activates the control panel 200 based on the input of the power-on command.

Based on the washing course selected by the user and received (281), the laundry treating device identifies current (i.e., today) weight estimation information (282) of the laundry.

The identification of the current (i.e., today) weight estimation information of the laundry may include identifying the current weight estimation information of the laundry when a washing program is received, an operation start command is received, option selection information is received, or a power-on command is received.

The identification of the laundry weight estimation information may include identifying at least one of a date, a season, weather, day of week and room temperature input to the input unit 210, and identifying at least one of a date, a season, weather, day of week and room temperature received through the communication circuit 260.

That is, the identification of the weight estimation information of the laundry includes identifying at least one of a current (i.e., today) date, season, weather, day of week, and room temperature.

The washing machine identifies a default time corresponding to the received washing course and the identified weight estimation information of the laundry based on the information stored in the storage device 250 and displays the identified default time on the display (283), thereby allowing the user to identify a time period required for washing.

This will be described by way of example.

When it is recognized that the weight estimation information is monday and the received washing course is normal washing, the washing machine recognizes the weight of the laundry in normal washing on monday among the information stored in the storage device, and displays a default time corresponding to the recognized weight of the laundry on the display.

Further, when it is recognized that the weight estimation information is monday and the received washing course is normal washing, the washing machine may recognize a default time of normal washing on monday among the information stored in the storage device and display the default time corresponding to the recognized weight of the laundry on the display.

This will be described with reference to fig. 6 and 7.

As shown in fig. 7, when it is recognized that the weight estimation information is monday and the received washing course is normal washing, the washing machine may recognize the weight of the laundry in the normal washing on monday among the information stored in the storage device and display a default time corresponding to the recognized weight of the laundry on the display.

For example, the washing machine identifies a weight level of normal washing performed on monday corresponding to the closest current monday (i.e., the latest monday) among weight levels of normal washing performed on monday, identifies a set time corresponding to the identified weight level, and displays the identified set time as a default time. In other words, the washing machine may recognize that the weight grade of the last laundry of the general washing on monday is the weight grade 1 of the number 5, and may display "a" as the default time corresponding to the weight grade 1.

As another example, the washing machine recognizes weight levels of the weight of the general washing performed on monday by a predetermined number, calculates an average level of the weight levels of the predetermined number of recognized general washing, recognizes a set time corresponding to the calculated average weight level, and displays the recognized set time as a default time.

The predetermined number of identified weight levels of the general wash on monday includes a weight level of the general wash on monday closest to the current predetermined number among the weight levels of the general wash on monday stored in the storage device.

For example, when the predetermined number is three, the washing machine may recognize the weight level 1 corresponding to the number 5, the weight level 1 corresponding to the number 4, and the weight level 1 corresponding to the number 3, calculate an average level of the recognized weight levels, and display the set time "a" corresponding to the calculated average level as the default time.

Further, when the average grade has a number with a decimal point, the washing machine may obtain the grade by rounding the decimal point.

As another example, the washing machine recognizes a weight level of a maximum value among weight levels of general washing performed on monday, recognizes a set time corresponding to the recognized weight level, and displays the recognized set time as a default time.

As still another example, the washing machine identifies a weight level of the minimum value among weight levels of general washing performed on monday, identifies a set time corresponding to the identified weight level, and displays the identified set time as a default time.

Further, when it is recognized that the weight estimation information is sunday and the received washing course is normal washing, the washing machine recognizes a default time of normal washing for sunday and displays the recognized default time. In other words, since the amount of laundry to be washed on weekends is greater than that of laundry on weekdays, the washing machine can estimate the weight of the laundry based on the day information.

As another example, when it is recognized that it is raining corresponding to the weight estimation information and the received washing course is a normal washing, the washing machine recognizes a default time of the normal washing in rainy weather and displays the recognized default time. When it is recognized that it is a sunny day and the received washing course is a normal washing, the washing machine recognizes a default time of the normal washing in the sunny day and displays the recognized default time.

In other words, since the drying performance is lowered due to high humidity at the time of rain, the amount of laundry may be reduced in rainy weather. Since the drying performance is improved due to low humidity in a sunny day, the amount of laundry may increase in a sunny day. Therefore, the weight of the laundry may be estimated based on the weather information.

As still another example, as shown in fig. 8A and 8B, when it is recognized that it is summer corresponding to the weight estimation information and the received washing course is normal washing, the washing machine recognizes a default time of the summer normal washing and displays the recognized default time. When it is recognized that it is winter time corresponding to the weight estimation information and the received washing course is normal washing, the washing machine recognizes a default time of the normal washing in winter time and displays the recognized default time.

In other words, since the winter laundry is thicker than the summer laundry, the weight of the laundry may be estimated based on the weather information.

As yet another example, the washing machine identifies a default time corresponding to the plurality of pieces of weight estimation information and the washing course, and displays the identified default time. This will be described with reference to fig. 8A and 8B.

As shown in fig. 8A, when it is recognized that saturday and summer corresponding to the weight estimation information, and when the received washing course is the normal washing, the washing machine recognizes that the weight level of the laundry of saturday in summer is 4, and the default time corresponding to the received weight level of 4 of the normal washing is "d", and displays the recognized default time "d" on the display. The identified default time may be selected according to a set time corresponding to the weight level.

As shown in fig. 8B, when it is recognized that monday and winter corresponding to the weight estimation information, and when the received washing course is the normal washing, the washing machine recognizes that the weight level of the laundry of monday in winter is 2, and the default time corresponding to the received weight level 2 of the normal washing is "B", and displays the recognized default time "B" on the display.

As yet another example, based on receiving the washing course, the washing machine identifies a point of time at which the last operation was performed, and identifies a stop period of the laundry treating apparatus between the identified last time and the current time. When it is recognized that the recognized stop period is the predetermined period or more, the washing machine may recognize a maximum laundry weight among the laundry weights detected in the past, recognize a set time corresponding to the recognized laundry weight and the received washing course, and display the recognized set time as a default time. This will be described with reference to fig. 9.

Assume that the predetermined period of time is six days.

As shown in fig. 9, when the washing course is received on thursday 16 (today), the washing machine recognizes the date on which the operation was last operated. When recognizing that the date of the last operation is wednesday No. 8, the washing machine may recognize that the stop period of the laundry treatment apparatus is eight days. When recognizing that the stop period of the laundry treating apparatus is six days or more, the washing machine may recognize that the highest level among the laundry weight levels detected in the past is five, and display a default time "e" corresponding to level 5 of the general washing course on the display.

Upon receiving the washing program, the washing machine may transmit a request command for providing the received washing program and a default time to at least one of the terminal 3 or the server 5, and upon receiving the default time from at least one of the terminal 3 or the server 5, the washing machine may display the received default time.

Upon receiving the washing course and the at least one option, the washing machine identifies a default time corresponding to the received washing course, the at least one option, and the identified weight estimation information of the laundry based on the information stored in the storage device 250, and displays the identified default time on the display.

The information stored in the storage device 250 may include information on a default time corresponding to each piece of weight estimation information of the laundry for each washing course, and may further include information on a default time corresponding to each piece of weight estimation information of the laundry for each option of the washing course.

For example, when it is monday and the received washing course is normal washing and the option is one additional rinsing corresponding to the weight estimation information of the laundry, the washing machine identifies default times corresponding to normal washing and one additional rinsing on monday and displays the identified default times.

As another example, when it is monday and the received washing course is normal washing and the option is an additional dehydration time of 5 minutes corresponding to the weight estimation information of the laundry, the washing machine identifies a default time corresponding to the normal washing of monday and the additional dehydration time of 5 minutes and displays the identified default time.

As still another example, when it is monday and the received washing course is normal washing and the options are additional 3-minute washing time and additional 5-minute dehydration time corresponding to the weight estimation information of the laundry, the washing machine identifies default times corresponding to the normal washing on monday and the additional 3-minute washing time and the additional 5-minute dehydration time, and displays the identified default times.

Upon receiving the operation start command, the washing machine detects the actual weight of the laundry by rotating the drum 140 while displaying a default time on the display (284).

The identification of the actual weight of the laundry includes detecting at least one piece of input-output information of the motor 150 configured to apply a rotational force to the drum 140, and detecting the weight of the laundry based on the detected at least one piece of information.

The washing machine identifies a weight level corresponding to the detected actual weight of the laundry, and displays an actual operation time corresponding to the identified level and the received washing course on the display (285).

The identifying of the actual operating time includes identifying a set time corresponding to the detected weight level among the weight levels of the received washing course, and identifying the identified set time. The identified set time may be an actual operating time.

Further, based on the option being selected, the washing machine may identify a weight level corresponding to the detected actual weight of the laundry, identify an actual operation time corresponding to the identified weight level, the received washing course, and the selected option, and display the identified actual operation time on the display.

That is, the washing machine changes the default time displayed on the display 220 to the actual operation time and then displays the actual operation time. This will be described with reference to fig. 11 and 12.

The washing machine displays a default time corresponding to the received washing course and the weight estimation information of the laundry on the display, and when an actual weight of the laundry contained in the drum is detected, the washing machine displays an actual operation time corresponding to the detected actual weight of the laundry and the received washing course on the display, and outputs a sound indicating that the time displayed on the display is changed.

As shown in fig. 11, when the actual weight of the laundry detected by the detector is less than the estimated weight of the laundry corresponding to the weight estimation information, the washing machine may display an actual operation time reduced compared to the default time on the display.

As shown in fig. 12, when the actual weight of the laundry detected by the detector is greater than the estimated weight of the laundry corresponding to the weight estimation information, the washing machine may display an increased actual operation time compared to the default time on the display.

Since the default time of the washing machine is displayed based on the weight estimation information of the laundry, the default time may not be significantly different from the actual operation time.

When the detection of the laundry weight is completed, the washing machine performs at least one of a washing cycle, a rinsing cycle, a dehydrating cycle, and a drying cycle based on the detected laundry weight and the received washing course (286).

Further, when the option is selected and the detection of the laundry weight is completed, the washing machine performs at least one of a washing cycle, a rinsing cycle, a dehydrating cycle, and a drying cycle based on the detected laundry weight, the received washing course, and the selected option.

During the execution of any one cycle, the washing machine re-recognizes the laundry weight corresponding to the detection information detected by the detector 230. The washing machine identifies whether the re-identified laundry weight is different from the laundry weight detected at the time of detecting the weight. When it is recognized that the two laundry weights are different from each other, the washing machine obtains a remaining time based on the remaining cycle in the received washing course and the re-recognized laundry weight, and displays the remaining time.

The sensing of the weight of the laundry during the execution of any one cycle may include re-sensing the weight of the laundry before the execution of at least one of the washing cycle, the rinsing cycle, the dehydrating cycle, and the drying cycle, or after the completion of at least one of the washing cycle, the rinsing cycle, the dehydrating cycle, and the drying cycle.

The washing cycle includes water supply, washing, draining, and intermediate dewatering, and the rinsing cycle includes water supply, washing, draining, and intermediate dewatering. The dehydration cycle includes final dehydration.

For example, when the weight of the laundry is re-detected before intermediate dehydration in one of the washing cycle and the rinsing cycle is performed, or when the weight of the laundry is re-detected before final dehydration is performed, the washing machine may detect the weight of the laundry in a wet state, and identify the actual weight of the laundry corresponding to the detected weight of the laundry based on the information stored in the storage device.

As another example, when the laundry weight is re-detected after performing the intermediate dehydration in one of the washing cycle and the rinsing cycle, the washing machine may detect the laundry weight in a dehydrated state, and identify the actual weight of the laundry corresponding to the detected laundry weight.

As still another example, when the weight of the laundry is re-detected after the final dehydration is performed or before the dry cycle is performed, the washing machine may detect the weight of the laundry in a dehydrated state and identify the actual weight of the laundry.

In addition, when the laundry weight is detected before the operation, the washing machine may detect the laundry weight after soaking the laundry in the drum by controlling the water supply.

The laundry weight is detected to recognize whether the user additionally puts the laundry through the auxiliary door. Further, the laundry weight may be detected in order to recognize whether the user takes out the laundry through the auxiliary door.

For example, when a washing cycle is completed, the washing machine detects the weight of laundry before performing a rinsing cycle. When the laundry weight is identified as being greater than the weight before the washing cycle, the washing machine identifies an increase in water supply time for increasing the amount of water used for rinsing, and identifies an additional time caused by additional rinsing. The washing machine adjusts the remaining time from the rinsing cycle to the dehydrating cycle or from the rinsing cycle to the drying cycle based on the selected additional time, and displays the adjusted remaining time.

That is, the laundry treating apparatus may display the remaining time by adjusting the remaining time according to the weight change of the laundry during the operation.

The laundry treating apparatus performs a washing operation based on the received washing course and the at least one option while detecting the weight of the laundry until all cycles corresponding to the received washing course are completed (287).

When the execution of the washing program is completed, the washing machine displays the actual operation time as the remaining time of the operation of the washing machine, and stores the detected laundry weight, the actual operation time, and the received washing program in the storage device.

Further, the detected weight of the laundry, the actual operation time, and the received washing program may be stored in the storage device when the detection of the weight of the laundry is completed.

Storing the various information in the storage device may include identifying a washing course and weight estimation information having the same condition as the received washing course and current weight estimation information among the information stored in the storage device, changing a default time corresponding to the identified washing course and weight estimation information to an actual operation time and storing the actual operation time, and changing a laundry weight corresponding to the stored default time to a detected laundry weight and storing the detected laundry weight.

For example, when the received washing course is the normal washing, the weight estimation information is monday, and the detected laundry weight is weight level 2, the washing machine may store the weight level 2 of the normal-washed laundry of monday in number 6 in the table of fig. 7, and further store the default time "b" corresponding to the weight level 2.

Storing the various information in the storage device may include identifying a washing course and weight estimation information having the same condition as the received washing course and current weight estimation information among the information stored in the storage device, obtaining an average time of a default time and an actual operation time corresponding to the identified washing course and weight estimation information, storing the obtained average time as a new default time, obtaining a laundry weight corresponding to the stored default time and an average weight of the detected laundry weight, changing the obtained average weight to a laundry weight corresponding to the new default time, and storing the laundry weight.

Storing the various information in the storage device may include identifying a plurality of washing courses and a plurality of pieces of weight estimation information having the same condition as the received washing course and the current weight estimation information among the information stored in the storage device, identifying a plurality of default times corresponding to the identified plurality of washing courses and the plurality of pieces of weight estimation information, changing an average time of the identified plurality of default times and an actual operation time to a new default time and storing the new default time, obtaining a plurality of laundry weights corresponding to the plurality of default times and an average weight of the detected laundry weights, changing the obtained average weight to a laundry weight corresponding to the new default time and storing the laundry weights.

Further, the washing machine may identify the laundry weights corresponding to the information having the same condition, obtain the identified laundry weights and the detected average weight of the laundry, identify a weight class corresponding to the obtained average weight of the laundry, identify a set time corresponding to the identified weight class, and store the identified set time as a default time.

The information having the same condition is information having the same washing course and weight estimation information as the received washing course and the identified weight estimation information among the information stored in the storage device 250.

Further, based on the option being selected, the washing machine displays an actual operation time and stores the detected laundry weight, the actual operation time, the received washing course, and the selected option in the storage device.

As described above, the washing machine updates the information stored in the storage device 250 by storing the actual operation time corresponding to the received washing course and the current weight estimation information of the laundry in the storage device 250 as a default time.

Accordingly, when operated later under the same washing course and weight estimation information, the washing machine may allow the default time to be displayed by using the currently obtained actual operation time.

Fig. 13 is a block diagram of a laundry treating apparatus according to another embodiment of the present disclosure. A laundry machine will be described as an example of a laundry treatment apparatus according to another embodiment of the present disclosure.

The washing machine according to another embodiment includes a water supply unit 170, a drain unit 180, a heating part 190, an inputter 210, a display 220, a detector 230, a processor 241, a storage device 251, a communication circuit 260, a driver 270, and a sound outputter 275.

The water supply 170, the drain 180, the heating section 190, the inputter 210, the display 220, the detector 230, the processor 241, the storage device 251, the communication circuit 260, and the driver 270 according to another embodiment are the same as the water supply 170, the drain 180, the heating section 190, the inputter 210, the display 220, the detector 230, the processor 240, the storage device 250, the communication circuit 260, and the driver 270 according to an embodiment, and thus descriptions thereof will be omitted.

The sound outputter 275 outputs a sound informing a time change displayed on the display according to a control command of the processor 241.

In other words, when the default time displayed on the display is changed to the set time, the sound outputter 275 outputs notification information indicating the time change as sound. The notification information may include a buzzer sound, a melody, and a bell sound.

Further, the sound outputter 275 may output a sound indicating a change in remaining time according to the addition of the laundry during the execution of the washing course selected by the user.

The sound outputter 275 may include a speaker.

Upon receiving the washing program input via the inputter 210, the processor 241 obtains a default time corresponding to the received washing program based on information stored in the storage device 251 and controls display of the obtained default time.

An example of obtaining the default time corresponding to the received washing course will be described.

For example, the processor 241 obtains a default time corresponding to the received washing course among default times of each washing course stored in the storage device 251, obtains a most recently stored default time among the obtained default times, and controls display of the obtained default time.

As another example, the processor 241 obtains a default time corresponding to the received washing program among default times of each washing program stored in the storage device 251, calculates an average time of the obtained default times, obtains the calculated average time as the default time, and allows the obtained default time to be displayed.

As yet another example, the processor 241 obtains a default time corresponding to the received washing program among default times of each washing program stored in the storage device 251, specifically, obtains a predetermined number of default times (i.e., the most recently stored default times), calculates an average time of the obtained default times, obtains the calculated average time as the default time, and allows the obtained default time to be displayed.

As still another example, the processor 241 obtains a default time corresponding to the received washing program among default times of each washing program stored in the storage device 251, obtains the longest default time among the obtained default times, and allows the obtained default time to be displayed.

As still another example, the processor 241 obtains a default time corresponding to the received washing program among default times of each washing program stored in the storage device 251, obtains the shortest default time among the obtained default times, and allows the obtained default time to be displayed.

The processor 241 may transmit the received washing program to the terminal 3 or the server 4 through the communication circuit 260 based on the received washing program. The processor 240 may receive the default time from the terminal 3 or the server 4 and control the display to allow the received default time to be displayed.

Upon receiving the washing course and the default time request information from the washing machine, the server 4 recognizes the identification information of the user of the washing machine and obtains a default time, which is stored in the washing machines of other users having the same condition as the recognized user's identification information, and transmits the obtained default time to the washing machine requesting the default time.

Upon receiving the washing program and the at least one option, the processor 241 obtains a default time corresponding to the received washing program and the at least one option based on the information stored in the storage device 250, and controls the display to display the obtained default time.

The information stored in the storage device 251 may include information on a default time of each washing course, and may further include information on a default time of each washing course corresponding to the addition of the option.

Further, the processor 241 may obtain a default time when a washing program is received, a start command is received, option selection information is received, or a power-on command is received.

Upon receiving the start command, the processor 240 recognizes the laundry weight corresponding to the detection information of the detector 230, recognizes the set time corresponding to the laundry weight and the received washing course, and allows the recognized set time to be displayed as the actual operation time on the display.

That is, after detecting the weight of the laundry, the processor 241 controls the operation of the display 220 such that the display 220 changes the default time displayed on the display 220 to the actual operation time and displays the actual operation time.

The processor 241 may allow the time change notification information displayed on the display to be output on the display 220 or through the sound outputter 275. The time change notification information represents notification information indicating a change from the default time to the actual operation time.

The processor 241 updates the information stored in the storage device 251 by storing an actual operation time corresponding to the received washing course as a default time in the storage device 251.

The processor 241 updates the information stored in the storage device 251 by identifying the same washing program as the received washing program among the information stored in the storage device 251 and accumulatively storing an actual operating time as default time information of the identified washing program.

Accordingly, when the washing machine is operated under the same washing course later, the processor 240 may allow the currently obtained actual operation time to be displayed as a default time.

When the actual operating time is stored as the default time in the storage device 251, the processor 241 may identify information having the same condition as the received washing course among the information stored in the storage device 251, identify the default time of the identified washing course, calculate an average time of the identified default time and the obtained actual operating time, and store the calculated average time as the default time.

Further, when the actual operation time is stored in the storage device 251 as the default time, the processor 241 may identify the laundry weight having information having the same condition as the received washing course, and calculate an average weight of the identified laundry weight and the detected laundry weight, and store the calculated average weight together with the average time.

When the actual operation time is stored in the storage device 251 as the default time, the processor 241 may identify the laundry weight of the same washing course as the received washing course among the information stored in the storage device 251, calculate the average weight of the identified laundry weight and the detected laundry weight, identify a weight class corresponding to the calculated average weight of the laundry, identify a set time corresponding to the identified weight class, and store the identified set time as the default time.

For example, when it is assumed that the laundry weight of the first general wash is 0.5kg, the laundry weight of the second general wash is 0.6kg, the laundry weight of the third general wash is 1.3kg, the laundry weight of the fourth general wash is 0.7kg, and the laundry weight of the fifth general wash is 0.4kg, the processor 241 obtains an average weight of 0.7kg five times (as a predetermined number of times), and calculates a level 1 corresponding to the obtained average weight, and stores a set time "a" corresponding to the level 1 as a default time.

When the actual operation time is displayed after the laundry weight is detected, the processor 241 may identify a weight level corresponding to the laundry weight, and identify a set time corresponding to the identified weight level and the washing course, and allow the identified set time to be displayed as the actual operation time.

The processor 241 re-recognizes the weight of the laundry corresponding to the detection information detected by the detector 230 during the execution of the washing program. When it is recognized that the re-recognized weight of the laundry is different from the weight of the laundry detected at the time of detecting the weight, the processor 241 obtains the remaining time based on the remaining cycle in the received washing course and the re-recognized weight of the laundry, and allows the display to display the obtained remaining time.

The processor 241 may output a notification message indicating the change of the remaining time as a sound through the sound outputter 275 according to the change of the weight of the laundry.

The change of the weight of the laundry includes an increase or decrease of the weight of the laundry.

The processor 241 may re-identify the weight of the laundry before performing at least one of the washing cycle, the rinsing cycle, the dehydrating cycle, and the drying cycle, or after completion of at least one of the washing cycle, the rinsing cycle, the dehydrating cycle, and the drying cycle.

Based on the reception of the operation start command, the processor 241 may control the operations of the water supply 160, the heating part 190, the drain 180, the blower (not shown), and the motor 150 based on the received washing course and option, so as to perform a washing cycle, a rinsing cycle, a dehydrating cycle, and a drying cycle corresponding to the selected washing course and at least one option.

Specifically, during the washing cycle, the processor 241 identifies the weight of the laundry corresponding to the detection information detected by the detector 230, and controls the washing cycle and the rinsing cycle by adjusting the amount of water based on the identified weight of the laundry and the washing course selected by the user, and controls the dehydrating cycle based on the identified weight of the laundry and the washing course.

When the washing course selected by the user includes the drying cycle, the processor 241 may control the drying cycle based on the weight of the laundry.

The processor 241 controls the operations of the water supply 160, the motor 150, and the drain 180 during the washing cycle and the rinsing cycle, and further controls the operation of the heating part 190 based on the selected water temperature. The processor 241 controls the operation of the motor 150 and the drainer 180 during the dehydration cycle, and the processor 241 controls the operation of the motor 150, the heating section 190 and the blower (not shown) during the drying cycle.

The processor 241 allows the display 220 to display the operation of the washing course selected by the user and at least one option.

The storage device 251 may store a set time per weight of the laundry in each washing course. For example, the washing program may include normal washing, bedding washing, boiling, wool washing, towel washing, and quick washing.

The storage device 251 may store a plurality of weight levels (e.g., large, medium, and small) corresponding to a plurality of weight ranges of the laundry, and store a set time of each washing course corresponding to each weight level.

As shown in fig. 14, the storage device 251 stores set times corresponding to weight ranks of general washing (such as large, medium, and small), set times corresponding to weight ranks of wool washing (such as large, medium, and small), and set times corresponding to weight ranks of bedding washing (such as large, medium, and small).

Further, the storage device 251 may store a cycle execution time for each cycle of the washing program corresponding to the weight grade.

The storage device 251 may store operation information of at least one washing course selected by the user by date.

As shown in fig. 15, the storage device 251 may store dates on which the washing machine is operated, at least one course selected by the user per date, weight levels of the laundry detected when the selected course is executed, and actual operating times of the washing machine corresponding to the weight levels. The actual operating time may be stored as a default time.

The storage device 251 accumulates operation information of a washing course selected by a user whenever the washing machine is operated, and stores the accumulated operation information.

Further, the storage device 251 may store a predetermined number of operation information of the washing course selected by the user, and the predetermined number is based on the latest date.

The storage device 251 may accumulate an actual operation time of each washing course, and may store the accumulated actual operation time and store the actual operation time of each washing course together with a date. The actual operating time may be stored as a default time.

As shown in fig. 16A, the storage device 251 may accumulate and store an actual operating time of the general washing. As shown in fig. 16B, the storage device 251 may accumulate and store the actual operation time of wool scouring.

The storage 251 may store information about a default time of each washing course as a look-up table. The default time may be a time based on the operation time.

The storage device 251 may update information about a default time of each washing course according to a control command of the processor 240.

The storage 251 may store a default time corresponding to at least one washing course selected by the user and at least one option selected by the user.

The options include at least one of water temperature, washing cycle time, rinsing cycle number, dehydration cycle intensity, and dehydration cycle time, and may further include at least one of drying cycle intensity, and drying cycle time.

The storage 251 may store at least one washing program selected by the user and store the weight of the laundry detected at the time of execution of the washing program.

The storage device 251 may store the number of family members, the sex and age of the user, and may store identification information of the laundry treating apparatus.

The storage 251 may include a volatile memory, such as a static random access memory (S-RAM) or a dynamic random access memory (D-RAM), for temporarily storing data, and a non-volatile memory, such as a read only memory, an Erasable Programmable Read Only Memory (EPROM), or an Electrically Erasable Programmable Read Only Memory (EEPROM), for storing data for a long time.

The communication circuit 260 includes wired/wireless communication, and performs communication with at least one of the electric equipment 2, the terminal 3, and the server 4.

The electrical equipment 2 may be a household appliance located in a house and capable of communication. For example, the electrical equipment 2 may be a refrigerator, a television, a microwave oven, an oven, or a dishwasher.

The terminal 3 is a mobile device capable of wired/wireless communication, and includes any one of a tablet computer, a smart phone, and a laptop computer.

The terminal 3 may store APPs that provide default times for each washing program.

The terminal 3 may display a default time for each washing program.

In addition, the terminal 3 can provide washing information for washing through a single APP. The washing information may include a default time of the washing program performed for each date, and operation information of the washing machine.

The communication between the washing machine corresponding to the laundry treatment apparatus 1 and the terminal 3, and the communication between the washing machine corresponding to the laundry treatment apparatus 1 and the electric equipment 2 include communication in a close contact state or within a predetermined distance.

That is, the communication circuit 260 performs wireless communication such as NFC, RFID, bluetooth, ZigBee, and WIFI with the electric equipment 2 and the terminal 3. Further, due to the cost of the communication circuit, the communication circuit 260 may perform short-range wireless communication with the electric equipment 2 and the terminal 3, such as NFC, RFID, bluetooth, and ZigBee.

The server 4 may be a washing information providing server that stores identification information of a washing machine corresponding to the laundry treatment apparatus 1 and identification information of a user, and manages the washing machine corresponding to the laundry treatment apparatus 1.

The identification information of the user may include an ID and a name of the user, the number of family members of the user, an age of the user, and a gender of the user.

The identification information of the washing machine may include at least one of a type, a model, a manufacture number, and a manufacturer of the washing machine.

The server 4 provides the washing machine with a default time for each washing program.

Fig. 17 is a flowchart of a washing machine according to another embodiment of the present disclosure, which will be described with reference to fig. 14, 15, 16A, and 16B.

The washing machine corresponding to the laundry treating apparatus activates the control panel 200 based on the input of the power-on command.

Based on the washing course selected by the user and received (291), the washing machine obtains a default time corresponding to the received washing course among the information stored in the storage device and displays the obtained default time (292).

Further, the washing machine may obtain a default time at a time when the operation start command is received and the option selection information is received.

The identification of the default time may include obtaining a default time corresponding to the same washing course as the received washing course among the default times of each washing course stored in the storage device 251.

For example, the washing machine identifies at least one default time corresponding to the received washing course among default times of each washing course stored in the storage device 251, obtains the most recently stored default time among the obtained default times, and displays the obtained default time on the display.

As another example, the washing machine identifies at least one default time corresponding to the received washing course among default times of each washing course stored in the storage device 251, calculates an average time of the obtained at least one default time, obtains the calculated average time as the default time, and displays the obtained default time on the display.

As still another example, the washing machine identifies at least one default time corresponding to the received washing course among default times of each washing course stored in the storage device 251, obtains a predetermined number of default times (i.e., the most recently stored default times) among the identified at least one default time, calculates an average time of the identified default times, obtains the calculated average time as the default time, and displays the obtained default times on the display.

As still another example, the washing machine identifies at least one default time corresponding to the received washing course among default times of each washing course stored in the storage device 251, obtains the longest default time among the identified at least one default time, and displays the obtained default time on the display.

As still another example, the washing machine identifies at least one default time corresponding to the received washing course among default times of each washing course stored in the storage device 251, obtains the shortest default time among the identified at least one default time, and displays the obtained default time on the display.

Based on the reception of the operation start command, the washing machine detects the actual weight of the laundry by rotating the drum 140 while displaying a default time on the display (293).

The identification of the actual weight of the laundry includes detecting at least one piece of input-output information of the motor 150 configured to apply a rotational force to the drum 140, and detecting the weight of the laundry based on the detected at least one piece of information.

The washing machine identifies a weight level corresponding to the detected actual weight of the laundry, and displays an actual operation time corresponding to the identified level and the received washing course on the display (294). The displayed operation time may be the remaining time of the operation of the washing machine.

The identifying of the actual operating time includes identifying a set time corresponding to the detected weight level among the weight levels of the received washing course and identifying the identified set time as the actual operating time.

Further, based on the option being selected, the washing machine may identify a weight level corresponding to the detected actual weight of the laundry, identify an actual operation time corresponding to the identified weight level, the received washing course, and the selected option, and display the identified actual operation time on the display.

When the laundry weight is detected, the washing machine changes the default time displayed on the display 220 to the actual operation time and displays the actual operation time, and outputs a time change notification message as a sound (295).

In other words, the washing machine displays a default time corresponding to the received washing course, and when an actual weight of laundry contained in the drum is detected, the washing machine displays an actual operation time corresponding to the detected actual weight and the received washing course.

When the detection of the laundry weight is completed, the washing machine performs at least one of a washing cycle, a rinsing cycle, a dehydrating cycle, and a drying cycle based on the detected laundry weight and the received washing course (296).

Further, when the option is selected and the detection of the laundry weight is completed, the washing machine performs at least one of a washing cycle, a rinsing cycle, a dehydrating cycle, and a drying cycle based on the detected laundry weight, the received washing course, and the selected option.

During the execution of any one cycle, the washing machine re-recognizes the laundry weight corresponding to the detection information detected by the detector 230. The washing machine identifies whether the re-identified laundry weight is different from the laundry weight detected at the time of detecting the weight. When it is recognized that the two laundry weights are different from each other, the washing machine obtains a remaining time based on the remaining cycle in the received washing course and the re-recognized laundry weight, and displays the remaining time.

The sensing of the weight of the laundry during the execution of any one cycle may include re-sensing the weight of the laundry before the execution of at least one of the washing cycle, the rinsing cycle, the dehydrating cycle, and the drying cycle, or after the completion of at least one of the washing cycle, the rinsing cycle, the dehydrating cycle, and the drying cycle.

The washing cycle includes water supply, washing, draining, and intermediate dewatering, and the rinsing cycle includes water supply, washing, draining, and intermediate dewatering. The dehydration cycle includes final dehydration.

For example, when the weight of the laundry is re-detected before intermediate dehydration in one of the washing cycle and the rinsing cycle is performed, or when the weight of the laundry is re-detected before final dehydration is performed, the washing machine may detect the weight of the laundry in a wet state, and identify the actual weight of the laundry corresponding to the detected weight of the laundry based on the information stored in the storage device.

As another example, when the laundry weight is re-detected after performing the intermediate dehydration in one of the washing cycle and the rinsing cycle, the washing machine may detect the laundry weight in a dehydrated state, and identify the actual weight of the laundry corresponding to the detected laundry weight.

As still another example, when the weight of the laundry is re-detected after the final dehydration is performed or before the dry cycle is performed, the washing machine may detect the weight of the laundry in a dehydrated state and identify the actual weight of the laundry.

In addition, when the laundry weight is detected before the operation, the washing machine may detect the laundry weight after soaking the laundry in the drum by controlling the water supply.

The laundry weight is detected to recognize whether the user additionally puts the laundry through the auxiliary door. Further, the laundry weight may be detected in order to recognize whether the user takes out the laundry through the auxiliary door.

For example, when a washing cycle is completed, the washing machine detects the weight of laundry before performing a rinsing cycle. When the laundry weight is identified as being greater than the weight before the washing cycle, the washing machine identifies an increase in water supply time for increasing the amount of water used for rinsing, and identifies an additional time caused by additional rinsing. The washing machine adjusts the remaining time from the rinsing cycle to the dehydrating cycle or from the rinsing cycle to the drying cycle based on the selected additional time, and displays the adjusted remaining time.

That is, the washing machine may display the remaining time by adjusting the remaining time according to the weight change of the laundry during the operation.

The washing machine performs a washing operation based on the received washing course and at least one option while detecting the weight of the laundry until all cycles corresponding to the received washing course are completed (297).

When the execution of the received washing program is completed, the washing machine stores the detected laundry weight, the actual operation time, and the received washing program in the storage device 251.

Storing the washing program and the operation time in the storage device 251 includes additionally storing an actual operation time as a default time corresponding to the washing program among the information stored in the storage device by using the received washing program.

Storing the washing program and the operation time in the storage device 251 may identify a default time of the washing program corresponding to the received washing program among the information stored in the storage device, calculate an average time of the identified default time and the actual operation time and store the calculated average time as the default time.

Further, based on the option being selected, the washing machine may display an actual operation time, and store the detected laundry weight, the actual operation time, the received washing course, and the selected option in the storage device.

As described above, the washing machine updates the information stored in the storage device by storing the actual operation time corresponding to the received washing course as a default time in the storage device 250.

Accordingly, when being operated later with the same washing course as the received washing course, the washing machine may allow the default time to be displayed by using the currently obtained actual operation time.

Fig. 18 is a block diagram of a laundry treating apparatus according to still another embodiment of the present disclosure.

The dryer 500 will be described as an example of a laundry treating apparatus according to another embodiment.

The inputter 510 transmits input information input by the user to the processor 540.

The display 520 displays a default time based on a control command of the processor 540 and displays an actual operation time of the dryer after a predetermined period of time has elapsed.

The predetermined period of time may be a period of time required to detect the weight of the objects to be dried and to identify the drying set time corresponding to the weight of the objects to be dried.

The display 520 may display the drying course selected by the user and at least one option selected by the user.

The display 520 displays the default time, the actual operation time, and the remaining time.

As shown in fig. 19, upon receiving the drying course, the display 520 of the dryer may display a default time corresponding to the received drying course and the weight estimation information of the objects to be dried.

As shown in fig. 20, upon receiving the drying operation command, the display 520 of the dryer performs weight detection of the objects to be dried and displays an actual operation time corresponding to the detected weight of the objects to be dried and the received drying course.

Further, when the weight of the object to be dried is changed while the object is dried, the display 520 of the dryer may obtain the remaining time based on the changed weight of the object to be dried, the received drying course, and the elapsed time, and display the obtained remaining time.

This may allow a user to quickly recognize the drying time.

The display 520 includes a plurality of seven segments.

The display 520 may include a flat panel display such as a Liquid Crystal Display (LCD), and may also include Light Emitting Diodes (LEDs).

The display 520 may be provided on a control panel of the dryer main body together with the input 510.

The detector 530 includes a weight detector configured to detect the weight of the objects to be dried (i.e., laundry). The objects to be dried include laundry, and may also include bedding and towels.

The detector 530 may be a sensor configured to detect at least one of input information and output information of the motor M1, and the motor M1 is configured to apply a rotational force to the drum when the drum rotates based on a control command of the processor 540. For example, the detector 530 may detect at least one of a current, a voltage, a torque, and a number of rotations of the motor M1.

Upon receiving the drying program input via the inputter 510, the processor 540 identifies current (i.e., today) weight estimation information of the objects to be dried, and identifies a default time corresponding to the received drying program and the identified weight estimation information of the objects to be dried based on the information stored in the storage 550, and controls display of the identified default time.

The processor 540 includes a timer configured to count the current weather and time. When identifying the current weight estimation information of the objects to be dried, the processor 540 may identify the current date and day of the week counted by the timer, and identify the current season based on the identified date.

The processor 540 may identify at least one of the date, season, weather, and day of the week input to the input 510, and further identify at least one of the date, season, weather, and day of the week received via the communication circuit 560.

Upon receiving the drying program input via the inputter 510, the processor 540 may recognize a default time corresponding to the received drying program and control display of the recognized drying time.

Upon receiving the drying program input via the inputter 510, the processor 540 may recognize the weight of the objects to be dried corresponding to the received drying program, recognize the set time corresponding to the recognized weight, and allow the recognized set time to be displayed as a default time.

The processor 540 may transmit the received drying program to the terminal 3 or the server 4 through the communication circuit 560 based on the reception of the drying program. The processor 540 may receive the default time from the terminal 3 or the server 4 and allow the display 520 to display the received default time.

Upon receiving the drying program and the default time request information from the dryer, the server 4 recognizes the identification information of the user of the dryer and obtains a default time, which is stored in the dryers of other users having the same condition as the recognized identification information of the user, and transmits the obtained default time to the dryer that requested the default time.

Upon receiving the drying course and the at least one option, the processor 540 identifies a default time corresponding to the received drying course, the at least one option, and the identified weight estimation information of the objects to be dried, based on the information stored in the storage 550, and allows the display to display the identified default time.

The weight estimation information of the objects to be dried includes at least one of day of the week, date, season, and weather.

The information stored in the storage 550 may include information on a default time corresponding to the weight estimation information of the objects to be dried for each drying course, and may further include information on a default time corresponding to the weight estimation information of the objects to be dried for each option of the drying course.

Further, the processor 540 may identify the weight estimation information of the objects to be dried when the drying program is received, the operation start command is received, the option selection information is received, or the power-on command is received.

The processor 540 may identify a stop period of the dryer based on the received drying program. When recognizing that the recognized stopping time period is the predetermined time period or more, the processor 540 may recognize a maximum weight of the objects to be dried among the weights of the objects to be dried detected in the past, and recognize the set time corresponding to the recognized weight of the objects to be dried and the received drying course, and allow the recognized set time to be displayed as a default time.

Upon receiving the drying program, the processor 540 may recognize whether the current date is a holiday. When recognizing that the current date is holiday, the processor 540 may recognize the maximum weight of the objects to be dried among the weights of the objects to be dried on the weekend or the weights of the objects to be dried detected in the past, recognize the set time corresponding to the recognized weight of the objects to be dried and the received drying course, and display the recognized set time as the default time.

Upon receiving the operation start command, the processor 540 recognizes the weight of the objects to be dried corresponding to the detection information of the detector 530, obtains a set time as a default time based on the weight of the objects to be dried and the received drying course, and controls the operation of the display 520 such that the display 520 changes the default time displayed on the display 520 to an actual operation time and displays the actual operation time.

The processor 540 may allow for the output of time change notifications displayed on the display 520 or through a speaker (not shown).

The processor 540 updates the information stored in the storage device by accumulatively storing actual operating time corresponding to the received drying course and the weight estimation information of the identified objects to be dried as default time in the storage device 550.

Therefore, when the dryer is operated later under the same drying course and weight estimation information of the objects to be dried, it is possible to allow the currently obtained actual operation time to be displayed as the default time.

When the actual operating time is stored in the storage 550 as the default time, the processor 540 may identify information having the same condition as the received drying course among the information stored in the storage 550, and store the identified default time and the obtained average time of the actual operating time as a new default time.

Further, when the actual operating time is stored in the storage 550 as the default time, the processor 540 may identify the weights of the objects to be dried corresponding to the information having the same condition, calculate an average weight of the identified weights of the objects to be dried and the detected weights of the objects to be dried, and store the calculated average weight together with the average time.

When the actual operating time is stored in the storage device 550 as the default time, the processor 540 may identify the weight of the objects to be dried corresponding to the information having the same condition, calculate the average weight of the identified weight of the objects to be dried and the detected weight of the objects to be dried, identify a weight class corresponding to the calculated average weight of the objects to be dried, identify a set time corresponding to the identified weight class, and store the identified set time as the default time.

The information having the same condition is information having the same drying program and weight estimation information of the objects to be dried as the received drying program and the weight estimation information of the identified objects to be dried among the information stored in the storage 550.

When the actual operation time is displayed after detecting the weight of the objects to be dried, the processor 550 may recognize a weight level corresponding to the weight of the objects to be dried, and recognize a set time corresponding to the recognized weight level and the drying course, and display the recognized set time as the actual operation time.

The processor 540 may re-identify the weight of the objects to be dried corresponding to the detection information detected by the detector 530 during the execution of the drying program. When it is recognized that the re-recognized weight of the objects to be dried is different from the weight of the objects to be dried detected at the time of detecting the weight, the processor 540 may obtain the remaining time and allow the display to display the obtained remaining time.

The processor 540 controls the operation of the display 520 to display the drying course selected by the user and at least one option selected by the user. Upon receiving the operation start command, the processor 540 controls the operations of the drum motor M1, the heating part 590, and the fan motor M2 based on the received drying program and option, thereby performing the drying program corresponding to the selected drying program and at least one option.

Specifically, during execution of the drying program, the processor 540 recognizes the weight of the objects to be dried corresponding to the detection information detected by the detector 530, and controls the drying program by adjusting the heating amount of the heating portion 590, the rotation amount of the drum, and the blowing amount of the fan based on the recognized weight of the objects to be dried and the drying program selected by the user.
