Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic flow chart of a clothes drying method according to an embodiment of the present application.

And step 110, acquiring control data of the current drying stage.

Specifically, for the clothes made of special materials, such as warm-keeping fluffy clothes, the drying stage may include a plurality of drying stages. Preferably, different drying stages may perform different drying operations to achieve different clothes drying purposes, or achieve the same purpose, but different drying degrees.

For example, some drying stages (or all drying stages) are to ensure that the filling material in the laundry does not agglomerate, some drying stages (or all drying stages) are to improve the bulkiness of the laundry, some drying stages (or all drying stages) are to ensure the flatness of the laundry, and so on. However, the drying objectives (or the same objectives, but different degrees) to be achieved in different drying stages are different, so that the control data corresponding to different drying stages may be different, and when entering the current drying stage, the control data of the current drying stage needs to be acquired.

And step 120, acquiring moisture indicating data of the clothes and the running time of the current drying stage after the drying operation of the current drying stage is executed according to the control data.

Specifically, the moisture content indicating data of the laundry is mainly index data indicating the moisture content of the laundry. In one specific example, the moisture content indicating data of the laundry may include, for example, a temperature difference between an air inlet and an air outlet of the drying apparatus. Or, moisture content data of the laundry (e.g., humidity data of the laundry) collected by a humidity sensor in the drying apparatus. The air inlet and the air outlet of the drying equipment can be respectively provided with a temperature sensor (or a temperature sensing bulb) for detecting the temperature of the air inlet and the temperature of the air outlet in real time. After the drying equipment acquires the temperature data of the air inlet and the temperature data of the air outlet respectively, the temperature difference between the temperature data of the air inlet and the temperature data of the air outlet is calculated and used as a measurement index of the moisture indication data.

Referring to fig. 2, fig. 2 is a partial schematic view of an internal structure of a drying apparatus, which specifically includes a spray valve, a filter screen, an air outlet temperature sensing bulb (for measuring the temperature of an air outlet), an evaporator, a condenser, a fan, an air inlet duct, a hose connecting an outer cylinder and a heat pump system, an air inlet temperature sensing bulb (for measuring the temperature of an air inlet), and a cylinder component, where each component in fig. 2 is a relatively conventional component and will not be described herein. Preferably, in this embodiment, the outlet air temperature bulb and the inlet air temperature bulb similar to those in fig. 2 are used to measure the outlet air temperature and the inlet air temperature, respectively, and the temperature difference between the two is obtained as the moisture content indication data.

And step 130, determining to repeatedly execute the drying operation of the current drying stage or execute the drying operation of the next drying stage according to the moisture indication data and the running time of the current drying stage.

Specifically, the moisture indication data and the running time of the current drying stage can be used for measuring whether the drying operation of the current drying stage is sufficient, and if the drying operation is sufficient, the next drying stage can be started to execute the drying operation; if the current drying operation is not enough, the drying operation in the current drying stage needs to be repeated until the current drying operation is ensured to be enough, and then the next drying stage is started.

And 140, stopping the drying operation when the drying stopping condition is met after the last drying stage in the plurality of drying stages is determined to execute the drying operation.

Specifically, the drying stage includes a plurality of stages, and each of the drying stages except for the last drying stage needs to perform the operation of completing the steps 110 to 130. The last drying stage is slightly different from the previous drying stage. The difference is that after the last drying stage performs the drying operation, if the drying operation is sufficient, the next drying stage is not needed to perform, but the drying operation can be directly stopped, that is, the drying stopping condition is satisfied. On the contrary, if the drying operation is not sufficient, the drying operation of the last drying stage needs to be repeatedly performed until the stop drying condition is satisfied, and the drying operation is stopped. The condition for stopping the drying operation is also determined according to the measured moisture content indicating data and the running time of the current drying stage after the drying operation is performed in the last drying stage. The specific process will be described in detail below, with particular reference to the following.

The clothes drying method provided by the embodiment of the invention comprises the steps of firstly obtaining control data of a current drying stage, and obtaining moisture indicating data of clothes and running time of the current drying stage after drying operation of the current drying stage is executed according to the control data. Whether to repeat the drying operation of the current drying stage or to perform the drying operation of the next drying stage is determined according to the moisture indication data and the running time of the current drying stage. And after the last drying stage in the drying stages executes the drying operation, judging whether the drying stopping condition is met currently, if so, executing the drying operation, and otherwise, continuing to execute the drying operation of the current drying stage. And after the execution is finished, continuing judging until the drying stopping condition is met, and stopping the drying operation. Preferably, different drying operations can be executed in different drying stages to achieve different drying purposes, for example, clothes are prevented from being agglomerated in certain drying stages, clothes are prevented from being deformed in certain stages, clothes reach certain fluffy degree and the like in certain drying stages, clothes reach certain drying degree in all stages, the flatness of the clothes is improved, when the clothes are finally dried, filling materials in the clothes can be ensured to be in a fluffy state, the clothes are in a flat state, meanwhile, the clothes are prevented from being damaged, and the condition of affecting the performance of the clothes is avoided.

On the basis of the above embodiments, the present application embodiment further provides another flow diagram of a laundry drying method, specifically referring to fig. 3 and 4. In this embodiment and other embodiments below, the multiple drying stages will be described by taking four drying stages as an example. See specifically below:

when the current drying stage is the first drying stage of the four drying stages, the control data of the current drying stage is obtained, as shown in fig. 3, which includes the following steps:

in step 310, preset data in the laundry washing process are acquired.

And 320, acquiring control data of the first drying stage according to preset data.

In a specific example, the preset data at least includes: the weight of the clothes after the clothes are dried, and the filling material of the clothes.

Then, the obtaining of the control data of the first drying stage according to the preset data may specifically include the following steps:

determining a first rotating speed and a first rotating-stopping ratio according to the weight of the clothes after the clothes are dried;

and determining the first operation time according to the weight of the clothes and/or the filling material of the clothes after the clothes drying operation.

Specifically, according to the weight of the laundry after the laundry drying operation, a first rotation speed and a first rotation-stop ratio of a first drying stage corresponding to the weight of the laundry are matched from a pre-constructed database.

In addition, the first operation time of the first drying stage corresponding to the weight of the clothes and/or the filling material after the clothes drying operation can be matched from the pre-constructed database according to the weight of the clothes and/or the filling material after the clothes drying operation.

Besides the parameters obtained from the pre-constructed database, the parameters can also be obtained in other manners, for example, manually input by a user, or called by other terminal devices or servers, and the specific obtaining manner is not limited, and can be determined completely according to actual situations.

Optionally, the preset data may further include a material of the clothes. When the current drying stage is the other drying stage except the first drying stage among the four drying stages, obtaining control data of the current drying stage, specifically referring to fig. 4, the method includes:

and step 410, extracting the rotating speed and the rotating-stopping ratio corresponding to the current drying stage from a pre-constructed database according to the material of the clothes.

Step 420, determining the operation time corresponding to the current drying stage according to the weight of the clothes and/or the filling material of the clothes before the drying operation of the current drying stage.

Similarly, besides obtaining the parameters from the pre-constructed database, the parameters may also be obtained in other manners, for example, manually input by a user, or called by other terminal devices or servers, and the specific obtaining manner is not limited, and may be determined completely according to actual situations.

Optionally, when determining to repeatedly perform the drying operation of the current drying stage or perform the drying operation of the next drying stage according to the moisture indication data and the running time of the current drying stage, reference may be made to the following method steps, specifically to fig. 5:

step 510, determining whether the moisture indication data of the current drying stage is less than or equal to a moisture indication threshold corresponding to the current drying stage;

step 520, it is determined whether the time that the current drying stage has been operated is greater than or equal to the operation time corresponding to the current drying stage.

In one case, when the moisture indication data is less than or equal to a moisture indication threshold corresponding to the current drying stage and the operating time in which the current drying stage has been operated is greater than or equal to the operating time corresponding to the current drying stage, the drying operation of the next drying stage is performed.

In other cases, when the moisture indication data is greater than the moisture indication threshold corresponding to the current drying stage, and/or the operating time in which the current drying stage has been operated is less than the operating time corresponding to the current drying stage, the drying operation of the current drying stage is repeatedly performed.

For example, the humidity indicating data is the temperature difference mentioned above, and if the temperature difference of the current drying stage is 8 degrees celsius, the humidity indicating data threshold value, that is, the temperature threshold value is 9 degrees celsius. The operation time corresponding to the current drying stage is 30 minutes, and the operation time of the current drying stage is 30 minutes, then the drying operation of the next drying stage can be performed.

Otherwise, the drying operation of the current drying stage needs to be repeatedly executed until the temperature difference value of the current drying stage is smaller than or equal to the temperature threshold value, and the next drying stage can be entered when the running time is larger than or equal to the running time corresponding to the current drying stage.

In an alternative example, the moisture content indicating data threshold of the current drying stage is determined according to the weight of the laundry before the current drying stage is operated, and/or according to the filling material of the laundry.

In the above embodiment, the manner of acquiring the control data of different drying stages, the operation sequence when performing the drying operation of different drying stages, and the like are described in detail. In the following embodiments, specific operation conditions of different drying stages will be described in detail.

Specifically, the operation condition of the first drying phase is that the drying device performs drying rotation according to the drying rotation speed in the control data, and when the drying operation is performed, a certain rotation-stop ratio is adopted, for example, as shown in table 1, the first drying rotation speed of the first drying phase may be 75rpm, and the first rotation-stop ratio is 110s-10s-110s-10s (forward rotation-stop-reverse rotation-stop). The moisture indication data, the moisture indication data threshold, the running time of the first drying stage, the running time corresponding to the first drying stage, and the like in the first drying stage can be obtained by the above-mentioned method, specifically referring to table 1, where table 1 shows that when the moisture indication data is the temperature threshold, a specific exemplary value of the first temperature threshold of the first drying stage is 9 degrees celsius. And the first drying stage corresponds to an operating time of 2 minutes.

TABLE 1

In fig. 6, a waveform diagram of the rotation speed of the first drying stage and the rotation-stop ratio of the first drying stage is provided, and specifically, as shown in fig. 6, the first drying stage firstly operates according to the forward rotation at a rotation speed of 75rpm, then stops operating for 10 seconds, then reversely rotates at 75rpm, then stops operating for 10 seconds, and at this time, completes the operation of one cycle. And detecting the current running time, and entering the next period if the running time corresponding to the first drying stage is not reached. In an alternative example, in addition to detecting the running time after executing one cycle, other time control manners may also be used to detect, for example, the running time is detected in real time, or, the detection is performed every fixed time, for example, every 30 seconds, and so on, and how to detect specifically may be determined according to actual conditions.

Because the filling material can be caked after the warm-keeping fluffy clothes are washed, the moisture content of the filling material is in the maximum position in the drying process after drying and dehydration, if general overturning drying is carried out, the caked filling material in the clothes can be further accumulated to the corners of the filling units, so that subsequent uniform drying cannot be carried out, and the caked part can not be effectively unfolded after drying.

Therefore, the clothes are operated at the first rotating speed in the first drying stage, the rotating speed is determined by the weight of the drying and weighing, the clothes are operated at the first rotating speed before entering the second stage, the clothes can still keep being attached to the drum to operate, the clothes are temporarily stopped in the middle process, the inner drum can operate and do not operate, namely, the reverse rotation time in the rotation-stop ratio can be replaced by the forward rotation. After first stage is dried, the moisture content of clothing descends, and the packing material obtains preliminary fluffy, and clothing inner space diminishes, does not paste a section of thick bamboo operation this moment, when overturning the stoving, and inside filler can not take place to pile up because of rotating the mechanical force again, can obtain the expansion of certain degree because patting on the contrary. In order to improve the drying efficiency and the drying uniformity, the second drying stage is performed when the condition of entering the next drying stage is met.

Optionally, when the current drying stage is a second drying stage of the four drying stages, the control data of the current drying stage includes a first group of control data, a second group of control data, and a second operation time, where the first group of control data includes a second rotation speed and a second rotation-stop ratio corresponding to the second rotation speed; the second set of control data includes: a third rotation speed and a third rotation-stop ratio corresponding to the third rotation speed, the second rotation speed being greater than the third rotation speed;

and in the second operation time, periodically and alternately operating according to the first group of control data and the second group of control data respectively. See table 2 for details:

TABLE 2

The control data in the second drying phase, including the first and second sets of control data, the second operation time, and the temperature threshold are illustrated in table 2. The second rotation speed in the first set of control data is 65rpm, the second rotation-stop ratio is 15s-10s-15s-10s (forward-stop-reverse-stop), the third rotation speed in the second set of control data is 55rpm, and the third rotation-stop ratio is 15s-10s-15s-10s (forward-stop-reverse-stop). Optionally, the first set of control data and the second set of control data may further include a duration period, respectively. For example, in table 2, the operation period according to the first set of control data is 1 cycle, and the operation period according to the second set of control data is 1 cycle. That is, in the second operation time, the operation is periodically alternated according to the first set of control data and the second set of control data, respectively. Whereas the overall operation time of the second drying phase is 5 minutes, an exemplary value of the second temperature threshold is 7 degrees celsius.

Fig. 7 shows a waveform diagram of the rotation speed and the rotation/stop ratio in the second drying stage. The contents shown in the specific waveform diagram are shown in table 2, and will not be described in detail here.

After the second stage drying, the moisture content of the clothes is further reduced, but the air with damp heat in the part between the filling materials is difficult to escape from the air in the drum for damp heat exchange.

Optionally, when the drying operation enters a third drying stage, the control data of the third drying stage includes a third set of control data, a fourth set of control data, and a third operation time, where the third set of control data includes a fourth rotation speed and a fourth rotation-stop ratio corresponding to the fourth rotation speed; the fourth set of control data includes: a fifth rotation speed and a fifth rotation-stop ratio corresponding to the fifth rotation speed, the fourth rotation speed being greater than the fifth rotation speed;

and in a third operation time, the drying equipment is respectively controlled to alternately operate according to a third group of control data and a fourth group of control data, wherein after a first preset period number is operated according to the third group of control data, the drying equipment is controlled to operate according to the fourth group of control data for a second preset period number, and the first preset period number is smaller than the second preset period number.

See in particular table 3 below:

TABLE 3

As can be seen from table 3, the control data for the third drying stage generally includes two sets, which are the third set of control data, the fourth set of control data, and the third operation time mentioned above.

Wherein the third group of control data comprises a fourth rotating speed of 200rpm, and the rotating-stopping ratio is 15s-5s (forward rotation-stopping rotation); the fourth set of control data includes a fifth speed of 55rpm with a spin-to-stall ratio of 15s-5s-15s-5s (forward-stall-reverse-stall). Optionally, the third set of control data and the fourth set of control data may further include an operation period during the alternate operation, respectively. For example, the third set of control data has an operation period of 1 cycle when it is operated alternately with the fourth set of control data, and the fourth set of control data has an operation period of 6 cycles. Namely, firstly, the operation is carried out for 1 period according to the third group of control data, then the operation is carried out for 6 periods according to the fourth group of control data, then the operation is carried out for 1 period according to the third group of control data, and then the operation is carried out for 6 periods according to the fourth group of control data. And so on, until the operation time of the third drying stage is greater than or equal to the third operation time, for example, 2 minutes in table 3, and the moisture content indicating data of the current drying stage, for example, the temperature difference value is less than or equal to 5 degrees celsius in table 3, the drying operation of the current drying stage may be stopped, the fourth drying stage may be counted, otherwise, the operation of the third drying stage is repeated.

In the third drying stage, a high rotating speed is used for generating a larger centrifugal force, pressure is generated between the clothes and the inner cylinder wall at the moment, air with higher moisture content in the clothes is extruded out of the clothes, then fluffing is carried out by using a low rotating speed in the third stage, the dry and hot air in the cylinder is refilled into the clothes, and the operating time of the low rotating speed is longer than that of the high rotating speed. The two rotation speeds have a duration period T, and the inside of the clothes can be repeatedly ventilated in such a reciprocating cycle, so that the internal moisture content is gradually reduced. Fig. 8 is a schematic diagram showing the waveform structure of the rotation speed and the rotation-stop ratio in the third drying stage, and particularly, fig. 8. The contents shown in fig. 8 correspond to the corresponding parameters in table 3 and are not described here too much.

TABLE 4

As can also be seen in table 4, the fourth drying phase likewise comprises two sets of control data, such as the fifth and sixth set of control data described above, and also a fourth run time. Wherein, the sixth rotation speed and the sixth rotation stop ratio corresponding to the sixth rotation speed included in the fifth group of control data are respectively as high rotation speed 65rpm, 15s-5s-15s-5s (forward rotation-stop-reverse rotation-stop) in table 4; the seventh speed, and the seventh spin-to-stall ratio corresponding to the seventh speed, included in the sixth set of control data are low speeds 55rpm, 15s-5s-15s-5s (forward-stall-reverse-stall), respectively, as in table 4.

Optionally, the fifth set of control data and the sixth set of control data may further include an operation period during alternate operation, respectively. For example, the fifth set of control data has an operation period of 1 cycle and the fourth set of control data has an operation period of 3 cycles when operating alternately with the sixth set of control data. Firstly, the operation is carried out for 1 period according to the fifth group of control data, then the operation is carried out for 3 periods according to the sixth group of control data, then the operation is carried out for 1 period according to the fifth group of control data, and then the operation is carried out for 3 periods according to the sixth group of control data. And so on, until the operation time of the fourth drying phase is greater than or equal to the fourth operation time, for example, 30 minutes in table 4, and the moisture indication data of the current drying phase, for example, the temperature difference value is less than or equal to 4 degrees celsius in table 4, it may be determined that the drying stop condition is satisfied, and the drying operation is stopped, otherwise, the drying operation of the fourth drying phase is repeatedly performed.

Fig. 9 is a schematic diagram illustrating a waveform structure of the rotation speed and the rotation/stop ratio in the fourth drying stage, and particularly, fig. 9. The contents shown in fig. 9 correspond to the corresponding parameters in table 4 and will not be described more extensively here.

And a fourth drying stage, which belongs to a fluffy drying stage, wherein the clothes are close to a drying state, effective beating among the clothes is required, and fluffy filling materials are filled. Optionally, the fourth drying stage may use the same rotation speed as the second drying stage, but the low-speed rotation time is longer than the high-speed rotation time, the high-speed rotation can effectively smooth out the twist between the clothes, and the low-speed rotation realizes fluffiness.

In an alternative example, in order to achieve the fluffing effect, in addition to the above-mentioned solution in which the control drying apparatus is operated for 1 cycle according to the sixth set of control data and then operated for 3 cycles according to the seventh set of control data alternately in this way, it is also possible to control the drying apparatus to be operated for 1 cycle according to the seventh set of control data after being operated for 1 cycle according to the sixth set of control data, respectively.

See table 5 for details:
