Technical Field
The present disclosure relates to a laundry treating apparatus. In particular, the present disclosure relates to a laundry treating apparatus in which an auxiliary drum is removable from a main drum, and a method of controlling the same.
Background
Laundry treatment apparatuses are devices for washing, drying, or refreshing laundry, and are provided in various forms, such as washing machines, dryers, washing dryers, and refreshers.
Unlike a refresher provided in the form of a closet, in which a space for receiving laundry is fixed, in a laundry treating apparatus performing washing or drying, a drum for receiving laundry is generally rotated.
The drum is formed in a cylindrical shape, and washing and drying may be performed while the laundry received in the drum moves as the drum rotates. For washing, the laundry treating apparatus includes a tub for receiving laundry. When washing is performed, the drum rotates within the tub.
The laundry treating apparatus may be classified into a front loading type and an upper loading type according to a direction in which laundry enters the drum or a rotational axis of the drum. In the front loading type, laundry is supplied into the drum from the front of the laundry treating apparatus, and the drum is rotated about a horizontal rotation axis parallel to the ground. In the top loading type, laundry is injected into the drum from above the laundry treating apparatus, and the drum is rotated about a rotation axis substantially perpendicular to the ground.
Generally, only one drum is provided in one washing machine or dryer. Therefore, separate washing or drying cannot be simultaneously performed according to the type of laundry. To solve such a problem, a laundry treating apparatus having two drums is recently provided. In the case of the laundry treating apparatus, two separate drums are provided in one housing, and washing and drying may be simultaneously performed in the two drums, respectively. Such a laundry treating apparatus may be referred to as a double laundry treating apparatus.
The dual laundry treating apparatus is a combination of a conventional laundry treating apparatus and a separate laundry treating apparatus. Therefore, although the dual laundry treating apparatus may be referred to as a single laundry treating apparatus, it may be a complex implementation of two laundry treating apparatuses in practice. This is because separate supplementary drums are provided above or below the existing drums, and a driving unit for driving the drums is inevitably provided separately in the double laundry treating apparatus. Therefore, the size of the double clothes treating apparatus is inevitably increased, and the complicated structure and manufacturing cost thereof are inevitably increased.
On the other hand, the drum in the washing machine may be referred to as an inner tub or an outer tub. In other words, the drum as a unit accommodating the laundry may be referred to as an inner tub. However, generally, the tub containing the washing water has a configuration not exposed to the user. Therefore, the drum may be simply referred to as a tub.
Accordingly, the dual laundry treating apparatus has a tub and a tub arranged in parallel, and may be referred to as a tub-by-tub laundry treating apparatus.
The applicant of the present invention has proposed korean patent application No. 10-2016-.
In the related art invention, separate washing may be performed in two separate drums, and an auxiliary drum may be inserted into the main drum to prevent the laundry treating apparatus from being increased in size. Further, since the driving force to rotate the auxiliary drum uses the driving force to rotate the main drum, a separate driving unit is not required. Therefore, the simple structure minimizes an increase in manufacturing cost.
The same type of laundry treating apparatus as the prior invention may be referred to as a laundry treating apparatus in which an auxiliary drum (second tub) containing laundry is inserted into a main tub (first tub) containing the laundry. Therefore, in order to distinguish this type of laundry treating apparatus from a tub-by-tub laundry treating apparatus, this type may be referred to as a tub-in-tub laundry treating apparatus.
However, the related art invention mainly discloses structural features of a tub-in-tub type laundry treating apparatus, and does not disclose a control method of effective washing.
For example, in a tub-in-tub laundry treating apparatus, after an auxiliary drum is mounted on a main drum, only laundry contained in the auxiliary drum may be washed. For ease of illustration, this may be referred to as "auxiliary washing". For ease of illustration, this may be referred to as "simultaneous washing". In addition, the apparatus may wash laundry in the auxiliary drum and the main drum together. For ease of illustration, this may be referred to as "simultaneous washing". These auxiliary washing and simultaneous washing are greatly different from "normal washing" in which the laundry contained in the main drum can be washed only after the auxiliary drum is separated.
In general washing, various algorithms are provided to enhance washing effects. However, in the case of the auxiliary washing and the simultaneous washing, research and development for performing the optimal washing have not been performed.
According to the above-described prior art, three different types of washing (auxiliary washing, simultaneous washing, and normal washing) can be performed as described above. Therefore, the need to provide a laundry treating apparatus capable of performing optimal washing in each of three different types of washing (auxiliary washing, simultaneous washing, and general washing) and a method for controlling the same cannot be emphasized too much.
In addition, in order to perform washing or rinsing, it is desirable to provide an appropriate amount of washing water according to the amount of laundry. For this, an accurate laundry amount must be first detected. However, in the case where only one drum is provided, many laundry amount sensing schemes are proposed, and when two drums are operated in an associated manner, the laundry amount of each drum cannot be accurately detected.
Therefore, it is necessary to provide a method capable of precisely detecting the main laundry amount and the auxiliary laundry amount, respectively, and performing an optimal laundry process according to the detected amounts.

In addition, the user may also visually and/or audibly recognize various information on the display unit, such as a current operation state of the laundry treating apparatus, an expected end time, and the like.
The above description about the
In the laundry treating apparatus according to one embodiment of the present disclosure, simultaneous washing and auxiliary washing as well as general washing may be performed. That is, the laundry treating apparatus 1 may perform a normal washing mode, a simultaneous washing mode, and an auxiliary washing mode. Any of these modes may be selectively performed according to the user's intention.
That is, although the general laundry treating apparatus performs only a single mode (i.e., a general washing mode), the laundry treating apparatus according to the present disclosure may also perform a simultaneous washing mode and an auxiliary washing mode. Therefore, it is highly undesirable to require excessive actions or confuse the user in order for the user to select one of these modes. In other words, it is desirable that the user can select a desired mode from the three modes and perform the corresponding laundry treatment with minimum behavior and without confusion.
First, an action of the user to separate the supplementary drum from the main drum may be necessary to perform the general washing mode. In addition, the act of the user mounting the supplementary drum on the main drum may be necessary to perform the supplementary washing mode and the simultaneous washing mode. In addition to these necessary actions, it is desirable that the user perform a minimum of actions for possible mode selection.
To perform the general washing mode, the user may separate the supplementary drum from the main drum, and then, as described above, the user may select the
To perform the simultaneous washing mode, the user may mount the supplementary drum on the main drum and select the input interface as described above. The simultaneous washing mode may then be automatically performed and terminated.
The motion performed by the user to perform the simultaneous washing mode may be the same as the user motion for the general washing mode, except that the supplementary drum is installed. As described above, the
Typically, a wash course comprises wash, rinse and spin cycles. When the user selects a specific course a in the general washing mode, the washing cycle, the rinsing cycle, and the dehydrating cycle may be sequentially performed according to the aforementioned algorithm. That is, the main drum may perform a general washing mode.
When the user selects the same course a in the simultaneous washing mode, the main drum may sequentially perform a washing cycle, a rinsing cycle, and a dehydrating cycle according to a previously described algorithm. In this regard, the simultaneous washing mode is a mode in which washing is performed by the supplementary drum. Therefore, even though the same course a, the washing cycle, the rinsing cycle and the dehydrating cycle in this mode may be different from the general washing mode and the simultaneous washing mode.
In one example, the washing cycle in the simultaneous washing mode may be divided into a washing cycle in which the main drum is mainly used and a washing cycle in which the auxiliary drum is mainly used. The former and the latter may be performed alternately or sequentially.
Therefore, the washing cycle in the simultaneous washing mode may include a washing cycle using the supplementary drum in addition to the washing cycle in the normal washing mode. The same principle applies to the rinsing cycle and the spin cycle.
The main washing cycle in most general washing modes is performed by driving the pulsator. In the laundry treating apparatus according to one embodiment of the present disclosure, the driving of the pulsator does not rotate the auxiliary drum or may not form a water current inside the auxiliary drum. Therefore, washing using the auxiliary drum is difficult to perform by driving the pulsator.
Therefore, in the simultaneous washing mode, a main washing cycle by driving the pulsator and an auxiliary washing cycle for rotating the main drum and thus generating a water current in the auxiliary drum may be alternately or sequentially performed.
In the auxiliary washing mode, the auxiliary drum is mounted on the main drum, but the laundry is not put into the main drum, but is put into the auxiliary drum only and washed therein. In this case, the main washing cycle driven by the pulsator is not performed. That is, it is possible to perform only the auxiliary washing cycle in which water flow is generated in the auxiliary drum using the rotation of the main drum.
In order to perform the supplementary washing mode, the user must mount the supplementary drum on the main drum. When the user makes the same selection as the above-described general washing mode, the simultaneous washing mode may be performed. That is, even if the laundry is not put into the main drum, the water supply to the main drum may be performed, and the main washing cycle may be performed.
The auxiliary washing mode is a mode in which only the auxiliary drum is used and relatively less washing is performed. In the past, the auxiliary washing mode may be a very rare and special case, taking into account the experience of the user using the laundry treating apparatus, washing using only the auxiliary drum without using the main drum.
Therefore, when the user wants to use the auxiliary washing mode, such specific recognition from the user must be reflected in the laundry treating apparatus. That is, it is preferable that, in the auxiliary washing mode, the selection is performed separately from the selection in the normal washing mode and the simultaneous washing mode.
Therefore, it is preferable that an auxiliary

A typical laundry treating apparatus includes a door switch. That is, a door switch is generally provided, which determines whether a door for opening and closing the laundry accommodating opening is closed. When the door is closed, the laundry treating apparatus stops operating. When the door is opened, the laundry treating apparatus may suddenly stop operating.
In the general laundry treating apparatus, when the user puts laundry in and closes the door, the user selects a course, etc., and then selects the start/pause input interface 202. Assuming that the door switch detects that the door is closed, the laundry treating apparatus starts a washing operation when the user inputs start/pause.
The laundry treating apparatus according to one embodiment of the present disclosure may further include such a

The laundry treating apparatus according to one embodiment of the present disclosure may implement the three modes as described above. These three modes involve the removal/attachment of the auxiliary drum. Therefore, it can be said that the time for detaching or not the supplementary drum is very important.
According to one embodiment of the present disclosure, when the user performs the start/pause input, it is desirable that the apparatus determines attachment or detachment of the supplementary drum. More specifically, after the
When the user selects a course on the course selection unit 202 and inputs start/pause, the laundry treating apparatus determines attachment or detachment of the supplementary drum before washing. In this regard, the control unit 100d makes this determination using the

Therefore, according to one embodiment of the present disclosure, the usage pattern of the present apparatus is the same as or substantially similar to that of a conventional laundry treating device. Therefore, the user can use the apparatus very easily. That is, in the present apparatus, the user interface is not complicated. Therefore, it is possible to prevent misunderstanding of the user in terms of operation in advance.
In addition, since it is possible to minimize the addition or modification of the configuration of the control panel 100 (e.g., the auxiliary washing selection unit), the manufacturing cost of the present apparatus is reduced, facilitating the production thereof.
The laundry treating apparatus according to one embodiment of the present disclosure determines whether to install the
According to one embodiment of the present disclosure, after the control unit determines whether the supplementary drum is loaded, an operation is performed to control the position of the water supply supplementary drum. In this case, the water supply is performed after the position of the supplementary drum has been located at the target position. This process may be accomplished by the

However, the predetermined rotation angle of this example may be set to have the same value as the predetermined rotation angle of the previous example. The preset rotation angle of this example may be set to be smaller than that of the previous example in consideration of the distance that the auxiliary drum slides.
As in the previous one example, when the

For example, when the sliding angle of the
In one embodiment, when the control unit performs the position control of the supplementary drum at an extremely low rotation speed of about 3RPM, the time required for the position control of the supplementary drum may be relatively long. That is, although the slip angle caused by inertia is negligible, and thus the position control of the supplementary drum is very simple, it has a disadvantage of requiring a lot of time.
On the other hand, when the slip angle is measured, the position control of the supplementary drum is performed using the measured slip angle, which is based on the inertia-induced slip angle. In other words, this method may allow the drum to be driven at a rotational speed that makes the inertial force sufficient to cause slippage. Therefore, although the position control of the supplementary drum is complicated in this method, the time required for the position control of the supplementary drum is short in this method.
In this regard, the position control of the supplementary drum may be a pre-operation of the water supply. Therefore, as the time required for the position control of the supplementary drum increases, the entire laundry treating time will also increase. Therefore, when performing position control of the assist drum using the slip angle, it is more desirable to add an algorithm rather than adding a new component.
Hereinafter, a method for controlling a laundry treating apparatus according to one embodiment of the present disclosure will be described in detail.
It is highly desirable to accurately measure the amount of laundry when performing washing and then perform washing according to the measured amount. This is because the amount of washing water, washing intensity, washing time, and the like can be appropriately controlled according to the amount of laundry, thereby obtaining an optimal washing effect. In recent years, a laundry treating apparatus that automatically injects detergent is also provided. Therefore, it is desirable to determine the amount of automatically dispensed detergent based on the measured laundry amount.
In the case of a general washing mode in which washing is performed using a main drum, various methods of detecting the amount of laundry are being used. In one example, when the main drum is rotated, the laundry amount may be measured according to a current value in the motor based on the load. That is, as the amount of laundry increases, the load of the motor also increases. Therefore, the value of the current flowing to the motor increases. Therefore, the amount of laundry in the main drum can be relatively accurately estimated from the current value.
However, in the laundry treating apparatus according to the present embodiment, the supplementary drum may be mounted on the main drum. Therefore, the motor load in the supplementary drum installation mode may be different from that in the general washing mode. That is, the load caused by the supplementary drum itself and the load caused by the amount of laundry inside the supplementary drum may be further increased. In particular, the size of the load may be further varied according to the state of the laundry received in the supplementary drum.
In one example, even in the same amount of laundry, the load of the motor may be different according to whether the laundry is dried or wet laundry. Further, when the main drum contains water, the load of the motor may be variable. Therefore, in the case of the simultaneous washing, it is not easy to estimate an accurate laundry amount in the main drum.
Further, in the case of the simultaneous washing or the auxiliary washing mode, it is not easy to estimate an accurate laundry amount within the auxiliary drum. This is because the driving of the subsidiary drum is not separately performed independently from the driving of the main drum. That is, there is no separate component, such as a separate motor for rotating the supplementary drum only.
Therefore, in a single laundry treating apparatus, there is a need to provide a method by which the amounts of laundry in the main drum and the supplementary drum can be accurately estimated in the case of the simultaneous washing mode, and by which the amount of laundry in the supplementary drum can be accurately measured in the case of the supplementary washing mode.
First, in the general washing mode, when the main drum is driven, the main laundry amount may be detected by using a current value flowing in the motor. As will be described later, a method of detecting the main laundry amount in the simultaneous washing mode may also be used.
In the auxiliary washing mode, the main drum is empty of laundry, and the auxiliary drum is mounted on the empty main drum. Therefore, it is not necessary to detect the laundry amount in the main drum. Since the subsidiary drum is mounted on the main drum, the subsidiary drum can also rotate together with the main drum. Therefore, the auxiliary drum may be used as a load added to a motor that rotates the main drum. In addition, when the washing water is supplied to the supplementary drum, the supplied washing water increases a load of the main drum. Therefore, it is desirable to detect the amount of auxiliary laundry in the auxiliary drum before the washing water is supplied.
Specifically, when the
As the amount of laundry in the supplementary drum increases, the measured current value also gradually increases. Accordingly, the current value calculated by subtracting the basic current value from the measured current value may be a current value corresponding to the amount of auxiliary laundry. The control unit may estimate the auxiliary laundry amount using the calculated current value. In this regard, the current and laundry amount table may be created by matching the measured current value with the corresponding auxiliary laundry amount. The
As another example, when the
In one embodiment, since the laundry is not put into the main drum in the auxiliary washing mode, the auxiliary laundry amount may be estimated relatively easily. However, in the case of the simultaneous washing mode, it is not easy to detect the main laundry amount and the auxiliary laundry amount. The control unit may measure a value of current flowing in the motor by rotating the main drum, as when measuring the amount of the auxiliary laundry. However, the magnitude of the measured most current value may be affected by the main laundry amount or the auxiliary laundry amount. Alternatively, both may affect the current value to the same extent.
Therefore, it is necessary to propose a method of effectively separately detecting the main laundry amount and the auxiliary laundry amount in the case of simultaneous washing.
According to this embodiment, the
The driving of the main drum as described above refers to driving in which the main drum and the pulsator are integrally rotated via the driving motor. The driving of the pulsator means that the main drum is kept not rotated and only the pulsator is rotated. The auxiliary drum is rotated by the rotation of the main drum. That is, the pulsator driving and the supplementary drum rotating are not related to each other.
When the main drum has a large main laundry amount, the driving resistance of the pulsator becomes larger. That is, the value of the current flowing in the motor driving the pulsator becomes larger. Accordingly, when the pulsator is driven, the control unit may detect the main laundry amount based on a current value flowing in the motor. Also, the measured current value is associated with the corresponding main laundry amount value, so that a table can be created therebetween. Accordingly, the control unit may determine the main laundry amount based on the table.
In one embodiment, the user puts the dry laundry into the main drum. Such dry laundry may be inserted into the main drum in a wrinkled state, and thus may not be in close contact with the
Therefore, preferably, in order to detect the main laundry amount, the main water supply S430 of supplying the washing water to the inside of the main drum is first performed. When the washing water is supplied, the dried clothes absorb moisture and become heavy, and then fall down due to gravity. Therefore, the wet laundry is in close contact with the pulsator. Then, the pulsator may receive sufficient resistance from the wet laundry. In this case, as the amount of laundry becomes larger, the resistance applied to the pulsator may be increased in proportion to the amount of laundry.
In this regard, the amount of washing water input at the main water supply S430 may be set in advance. That is, a predetermined amount of washing water may be supplied. The predetermined amount may be referred to as a basic amount of washing water. The basic amount of washing water may indicate an amount of washing water for a minimum amount of laundry. In this regard, the adjustment of the amount of washing water may be performed by adjusting the water supply time. In one embodiment, the apparatus may also adjust the amount of wash water using a water level sensor provided in the tub. The water level sensor provided in the tub has a general configuration, and thus a detailed description thereof will be omitted.
The control unit may measure a current value at the motor based on the increase and decrease of the amount of washing water and the amount of laundry. The current values measured based on the increase and decrease of the basic amount of washing water and the amount of laundry may be tabulated. That is, when the current value is measured, the main laundry amount corresponding to the measured current value may be determined. In this regard, as the measurement current value becomes larger, the main laundry amount may also become larger.
In this regard, the current value sensed when the main laundry amount is detected may be a value measured in the motor when the motor drives the pulsator. Since the control unit has detected the main laundry amount, the control unit can drive the main drum in consideration of the main laundry amount, thereby determining the auxiliary laundry amount.
When the amount of the auxiliary laundry increases with respect to the detected main laundry amount, a current value flowing in the motor when the main drum is driven increases. In this regard, the measured current value may be a sum of a load caused by the main laundry amount and a load caused by the auxiliary laundry amount. In addition, the current value may be obtained in advance in the case of the same main laundry amount and in the case of no auxiliary laundry amount. A difference between a previous current value in the case where the auxiliary laundry amount exists and a subsequent current value in the case where the auxiliary laundry amount does not exist may be calculated. The control unit may estimate the auxiliary laundry amount based on the calculated value. In this regard, when the current value difference increases, it means that the auxiliary laundry amount is larger.
Accordingly, the auxiliary laundry amount may be determined as follows. The control unit may first determine the main laundry amount and then determine the auxiliary laundry amount based on the determined main laundry amount. In this regard, it may be appreciated that, in order to detect or determine the auxiliary laundry amount, the control unit preferably drives the main drum.
In one embodiment, the control unit can detect the auxiliary laundry amount using the slip angle without using the current value. When the main laundry amount is large, the slip angle increases. However, since the main laundry amount is first detected, the slip angle may be previously obtained according to the detected main laundry amount.
In addition, when an auxiliary laundry amount is added in addition to the main laundry amount, the slip angle may be further increased. That is, as the amount of the auxiliary laundry increases, the slip angle occurring after the rotation of the main drum until the main drum is stopped further increases. Therefore, the slip angle may be tabulated based on the auxiliary laundry amount for each main laundry amount. The control unit may estimate the auxiliary laundry amount based on a relationship between a predetermined main laundry amount and a slip angle.
Therefore, according to the present embodiment, even in the simultaneous washing mode, the control unit can accurately estimate the main laundry amount and the auxiliary laundry amount and perform the optimum washing based on the estimated values. In particular, the present disclosure may provide a more effective method to separately detect the main laundry amount and the auxiliary laundry amount, thereby excluding the influence of the auxiliary laundry amount on the detection of the main laundry amount, and thus, separately perform the measurement or detection of the auxiliary laundry amount and the main laundry amount.
As described above, the
Therefore, it is preferable that the
In this regard, the following problems arise. That is, it is impossible to detect or distinguish the initial remaining amount of water from the auxiliary laundry amount due to the nature of the
That is, the user may put wet laundry into the
Therefore, the target water amount in the supplementary drum cannot be correctly known regardless of whether the water amount in the supplementary drum is large or small. Further, the larger the amount of water initially remaining, which results in an incorrect amount of the auxiliary laundry amount being detected from the perspective of the auxiliary laundry amount as described above, regardless of the actual auxiliary laundry amount. Therefore, the control unit cannot detect the correct target auxiliary laundry amount.
In one example, the user may perform rough washing in the supplementary drum. Thereafter, the user may mount the supplementary drum filled with water and laundry to the main drum. This is often the case for users who want to conserve water. The main drum as described above may also detect the amount of water using a water level sensor mounted thereon. This is for the following purposes: the control unit may sense the amount of water via the water level sensor before the main water supply, and reduce the amount of the main water supply or omit the main water supply, if necessary. Accordingly, the main laundry amount is detected via the driving of the pulsator, and in the case of the main drum, the influence of the amount of water initially remaining in the main drum on the detection of the main laundry amount may be minimized.
However, according to this embodiment, it is not easy to provide a method of minimizing the influence of the amount of water initially remaining in the supplementary drum on the measurement or detection of the amount of supplementary laundry.
Accordingly, when the supplementary drum is filled with the initially remaining water, the amount of the supplementary laundry in the supplementary drum can be maximally detected. In this case, the washing water is supplied to the supplementary drum at a maximum amount corresponding to the maximum supplementary laundry amount. In this regard, the supplied washing water may overflow the supplementary drum. This situation is not ideal. This is because the washing water may be wasted, and the user may misunderstand the same as a malfunction of the laundry treating apparatus. In addition, there is a problem: the correct target amount of washing water cannot be supplied due to the initially remaining water.
Therefore, as shown in fig. 6, according to one embodiment of the present disclosure, it is preferable that the temporary dehydrating operations S310 and S410 are performed when the auxiliary washing mode S300 and the simultaneous washing mode S400 are initiated. That is, it is desirable to first discharge water initially contained in the supplementary drum before supplying water to the supplementary drum.
The temporary dehydration may be accomplished via the rotation of the main drum to discharge water inside the supplementary drum to the outside of the supplementary drum using centrifugal force. When water is initially present in the supplementary drum, contaminants therein are discharged together with the water through temporary dehydration. This is not to waste water but to improve the efficiency of the subsequent use of the supplementary drum washing. Temporary dewatering may allow a large amount of water to be drained along with contaminants therein. Therefore, the decomposition of the detergent on the contaminants can be further promoted in the subsequent washing process.
When the laundry inside the supplementary drum is washed using the rotation of the main drum, the main drum may rotate at about 90 to 100 RPM. At this RPM level, a sufficient water flow can be generated in the supplementary drum. When the rotational RPM of the main drum increases, the water in the auxiliary drum moves radially outward and upward by centrifugal force. Accordingly, when the rotation RPM of the main drum is about 120 to 130RPM, the water in the supplementary drum may be discharged to the outside by a centrifugal force.
However, when the temporary period of the temporary dehydration is extended, the entire washing time may be increased. Therefore, it is desirable to increase the rotation RPM of the main drum so that water is rapidly discharged to the outside of the supplementary drum. However, when the rotation RPM of the main drum becomes excessively high, a problem that the discharged water is scattered outward may occur. Where the RPM approaches approximately 270RPM, the water may scatter outward. Therefore, it is desirable to perform temporary dewatering at RPM (in one example, 270RPM) before the water scatters.
Typically, the main spin-drying RPM of the main drum is greater than 400RPM (including 400 RPM). Therefore, when the main drum is primarily dehydrated at the RPM speed, the water in the auxiliary drum may be scattered. Therefore, in the dehydration operation in the simultaneous washing mode, the main drum dehydration is preferably performed after the supplementary drum dehydration.
Specifically, at the time of dehydration start, water in the tub is drained by driving the drain pump. Therefore, a large amount of water is discharged from the main drum.
Temporary dewatering is then initiated at about 270 RPM. During the temporary dewatering, the water in the main drum is discharged to some extent by centrifugal force.
After the temporary spinning, the main drum is rotated at more than 400RPM (including 400RPM), and the non-temporary spinning is performed. In the temporary dehydration, a large amount of washing water is drained from the supplementary drum. Therefore, the amount of water scattered during the main dehydration is small. Therefore, performing the main drum dehydration after the temporary dehydration may allow water in the laundry located in the auxiliary drum and the main drum, respectively, to be sufficiently drained.
Hereinafter, the general washing mode, the auxiliary washing mode, and the simultaneous washing mode will be described in detail with reference to fig. 6.
Since these three modes can be performed in one washing machine, it is necessary to determine whether the supplementary drum is installed. According to the determination result, any one of the above three modes may be performed.
When the supplementary drum is not installed, the general washing mode S200 may be performed.
The normal washing mode S200 may be performed while the normal water supply S210 is activated. At the time of the normal water supply S210, a small amount of washing water is supplied. Thereafter, the laundry amount detecting operation S220 may be performed. If necessary, based on the detected laundry amount, the additional water supply S230 may be performed.
When the water supply is completed, the normal washing mode may be automatically performed S240, and then S500 is terminated. The general washing may include washing, rinsing and dehydrating operations. That is, the washing cycle, the rinsing cycle, and the dehydrating cycle may be performed in sequence according to the above algorithm. In this regard, the driving manner of the main drum and the pulsator will be the same as or similar to that in the conventional laundry treating apparatus. Such driving may be referred to as normal driving.
That is, when the user selects a course without attaching the supplementary drum to the main drum, the general washing mode may be automatically performed and terminated.
When the supplementary drum is mounted to the main drum, the supplementary washing mode S300 may be performed.
The auxiliary washing mode S300 may be performed while the auxiliary laundry amount sensing operation S320 is initiated.
The auxiliary laundry amount sensing operation S320 may be performed by driving the main drum. In one embodiment, it is desirable to perform the temporary spinning S310 before the auxiliary laundry amount detecting operation S320 in order to detect the correct auxiliary laundry amount.
When the auxiliary laundry amount is detected, the washing water should be supplied to the auxiliary drum S340 based on the detected auxiliary laundry amount. In order to perform the auxiliary water supply S340, the auxiliary drum position control S330 is preferably performed.
Performing the water supply may allow the washing water to be supplied only to the supplementary drum after the supplementary drum position control is performed.
The supplementary drum position control means rotating the supplementary drum so that a specific portion of the supplementary drum stops at a specific position. Preferably, in order to facilitate the user to separate the supplementary drum from the main drum using the handle, the handle is located at a specific position (in one example, in a horizontal direction).
When the supply of the washing water is completed, the auxiliary washing may be automatically performed S350 and the auxiliary washing may be terminated S500. Also, the supplementary washing may include washing, rinsing, and dehydrating. That is, the washing cycle, the rinsing cycle, and the dehydrating cycle may be performed in sequence according to the above algorithm. In this regard, the driving manner of the main drum and the pulsator will be different from that in the conventional laundry treating apparatus. The pulsator driving will be omitted. The driving of the main drum may include only a driving for generating a water current inside the supplementary drum and a driving for dehydrating. Such a drive may be referred to as an auxiliary drive.
When the supplementary drum is mounted to the main drum, the supplementary washing mode S300 may be performed.
The simultaneous washing mode S400 may be performed while the main drum laundry amount sensing operation S440 is initiated. The main drum laundry amount detecting operation S440 may also be performed by driving a pulsator. In one embodiment, after the main water supply S430, the main drum laundry amount detection S440 may be performed in order to detect a correct main laundry amount and to exclude the influence of the auxiliary laundry amount. Further, in order to perform the main water supply S430, the supplementary drum position control S420 may be performed. This allows the washing water to be supplied only to the main drum, not to the supplementary drum.
In one embodiment, after the main drum laundry amount sensing operation S440, the additional water supply S450 may be performed. That is, the control unit may additionally supply the washing water based on the detected main laundry amount, if necessary. When the additional water supply is completed, it may be considered that the preparation for washing the laundry within the main drum is completed.
In order to wash the laundry within the supplementary drum, a supplementary drum laundry amount sensing operation S460 may be performed. In this regard, the supplementary drum laundry amount sensing operation S460 may be performed by driving the main drum.
It is preferable that the water initially remaining in the supplementary drum is drained so as to accurately detect the supplementary laundry amount. Therefore, the temporary spinning S410 is preferably performed before the supplementary drum laundry amount sensing S460 is performed. The temporary spinning S410 may be performed before the supplementary drum laundry amount sensing S460 and after the additional water supply S440. The simultaneous washing mode S400 may be performed by starting the temporary spinning S410.
When the auxiliary laundry amount is detected, the auxiliary water supply S480 may be performed based on the detected auxiliary laundry amount. For the supplementary water supply operation S480, it is preferable that the supplementary drum position control S470 is first performed. When the supplementary water supply S480 is completed, it may be considered that preparation for washing the laundry within the supplementary drum is completed.
When the supply of the washing water is completed, the S490 simultaneous washing mode may be automatically performed, and the S500 simultaneous washing mode may be terminated. Also, the simultaneous washing may include washing, rinsing, and dehydrating. That is, the washing cycle, the rinsing cycle, and the dehydrating cycle may be performed in the order of the above algorithm. In this regard, the main drum and pulsator driving manner will be a mixture of the normal driving and the auxiliary driving. These normal and auxiliary driving operations are performed sequentially or alternately. As a result, the main washing and the auxiliary washing may be simultaneously performed and may be simultaneously completed.
As described above, in the simultaneous washing mode S400, there are at least three stages (i.e., the main stage, the auxiliary stage, and the additional stage) in the water supply. For this purpose, at least two auxiliary roller position controls are carried out. In this regard, the supplementary drum position control may be an operation independent of the washing. The time required for the control operation increases the total washing time. Therefore, it is preferable that the supplementary water supply S480 is performed after the main water supply S430 and the additional water supply S450 are all terminated.
In one embodiment, a configuration after performing the supplementary water supply S480, the main water supply S430, and the additional water supply S450 may be desirable in terms of two supplementary drum position control. However, since the main laundry amount must be detected first and then the auxiliary laundry amount must be detected, a configuration in which the auxiliary water supply is performed after the main water supply and the additional water supply is desirable in terms of the laundry amount detection.
As described above, the general washing mode may be performed in the same manner as the general washing machine. In one embodiment, in this case, a further operation may be performed to determine whether the supplementary drum is mounted. However, when the supplementary drum is installed, the supplementary washing mode or the simultaneous washing mode must be performed. Therefore, it is necessary to clearly distinguish the auxiliary washing mode from the simultaneous washing mode in order to prevent malfunction or missensing.
In one example, when the auxiliary washing mode needs to be performed, the simultaneous washing mode is performed, or the reverse needs to be prevented in advance. In the former case, washing water and time are unnecessarily consumed, and in the latter case, the laundry in the main drum may not be washed. Therefore, the user may need to actively select the supplementary washing mode or the simultaneous washing mode and mount the supplementary drum on the main drum. This can be tedious.
When the supplementary drum is installed, the supplementary washing mode or the simultaneous washing mode may be performed according to whether the supplementary washing mode is selected. When the auxiliary washing is selected via the auxiliary
In one embodiment, the device may have an auxiliary wash input interface and a simultaneous wash input interface to prevent misdirection and confuse the user. The user may select the auxiliary wash input interface or the simultaneous wash input interface. That is, the apparatus may be configured such that both the auxiliary wash input interface and the simultaneous wash input interface are exclusively selected.
As shown in fig. 5, when the user inputs the auxiliary washing mode, the auxiliary washing mode may be performed based on the determination result from the S160 operation. As shown in fig. 5, when the user inputs the simultaneous washing mode, the simultaneous washing mode may be performed based on the determination result from the S160 operation.
As shown in fig. 5, when the user inputs the auxiliary washing mode, an error indication S150 may be performed based on the determination result from the operation of S140. As shown in fig. 5, when the user inputs the simultaneous washing mode, an error indication S150 may be performed based on the determination result from the operation of S140. In one embodiment, when the user inputs the simultaneous washing, it may be negated in the operation of S140 shown in fig. 5, but the general washing mode may be performed.
As described above, although the present disclosure is described by the embodiments and the drawings defined above, the present disclosure is not limited thereto. Rather, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
