A self-cleaning control method, apparatus, clothing treatment equipment, and storage medium

Abstract

This application discloses a self-cleaning control method, apparatus, clothing processing equipment, and storage medium. The method includes: determining that self-cleaning conditions are met, controlling a reversing valve to switch the water flow channel to the self-cleaning channel; and starting a water pump to perform a self-cleaning operation, driving water in a water collection container to be sprayed onto the evaporator through the self-cleaning channel. Thus, upon determining that self-cleaning conditions are met (e.g., the water volume in the water collection container reaches a certain amount, or the self-cleaning time has been reached), the reversing valve is first controlled to switch the water flow channel to the self-cleaning channel, and then the water pump is started to pump water from the water collection container into the self-cleaning channel for self-cleaning. Because the water pump is stopped when switching the reversing valve, it can prevent impurities such as lint in the water flow from adhering to the reversing valve during the switching process, thus avoiding blockage and extending the valve's lifespan.

Description

TECHNICAL FIELD

[0001] The present application relates to laundry processing technology, and in particular to a self-cleaning control method and device, a laundry processing apparatus, and a storage medium. BACKGROUND

[0002] During the drying process, a large amount of lint and other impurities will be generated from the laundry, and the fine lint and other impurities will adhere to the evaporator. Therefore, a self-cleaning operation needs to be performed on the dryer to clean the lint and other impurities adhering to the evaporator. However, the existing dryer usually starts to switch the water flow channel by using the reversing valve during the operation of the water pump. Since there are lint and other impurities in the water flow at this time, the lint and other impurities will block the reversing valve when the reversing valve switches the water flow channel at this time, thereby affecting the normal operation of the reversing valve and shortening the service life of the reversing valve.

[0007] The water pump is started to perform a self-cleaning operation, and the water in the water storage container is sprayed toward the evaporator through the self-cleaning channel.

[0008] In the above solution, the self-cleaning condition includes:

[0009] The water amount in the water storage container during the drying operation is greater than or equal to a preset first water amount threshold value.

[0010] Alternatively, a preset self-cleaning time is reached during the drying operation, and the self-cleaning time is a first time before the end of the drying operation.

[0011] In the above solution, the starting of the water pump to perform the self-cleaning operation includes:

[0012] When the water amount in the water storage container during the drying operation is greater than or equal to the preset first water amount threshold value, the water pump is started to perform a self-cleaning operation for a first time length.

[0013] Alternatively, when the preset self-cleaning time is reached during the drying operation, the water pump is started to perform a self-cleaning operation for a second time length.

[0014] The first time length is greater than the second time length.

[0015] In the above solution, the method further includes determining that the self-cleaning operation is completed, and turning off the water pump.

[0016] In the above solution, the method further includes determining that the water pumping condition is met, and controlling the reversing valve to switch the water flow channel to the water pumping channel; starting the water pump to perform a water pumping operation, and driving the water in the water accumulation container to flow into the water drainage container through the water pumping channel.

[0017] In the above solution, the water pumping condition includes that a drying operation process reaches a preset water pumping time; the water pumping time is a second time before the end of the drying operation; or it is determined that the self-cleaning operation is completed.

[0018] In the above solution, the method further includes determining that the water pumping operation is completed, and turning off the water pump.

[0019] In a second aspect, a self-cleaning control device is provided, and the device includes:

[0020] a first control unit configured to determine that a self-cleaning condition is met, and control the reversing valve to switch the water flow channel to the self-cleaning channel;

[0021] a second control unit configured to start the water pump to perform a self-cleaning operation, and drive the water in the water accumulation container to spray towards the evaporator through the self-cleaning channel.

[0022] In a third aspect, a laundry treatment apparatus is provided, and the laundry treatment apparatus includes a processor and a memory configured to store a computer program capable of running on the processor,

[0033] In order to enable the person skilled in the art to better understand the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings, and the accompanying drawings are only used for reference and do not limit the embodiments of the present application.

[0034] The embodiment of the present application provides a self-cleaning control method, which is applied to a clothes processing device, and the clothes processing device has a clothes drying function and a self-cleaning function. For example, the clothes processing device can be a clothes dryer, a dry cleaning all-in-one machine or other devices.

[0035] Exemplarily, Figure 1 A first constituent structure diagram of the clothes processing device in the embodiment of the present application is shown in the figure, Figure 1 The clothes processing device 10 includes an evaporator 101, a water accumulation container 102, a drainage container 103, a water pumping device 104, a reversing valve 105, a self-cleaning channel 106, a spray head 107 and a water pumping channel 108.

[0036] The water accumulation container 102 receives condensed water flowing from the evaporator 101;

[0037] The reversing valve 105 is connected to the self-cleaning channel 106 and the water pumping channel 108, and switching the communication direction of the reversing valve 105 can make the lower part of the common channel of the reversing valve 105 communicate with the self-cleaning channel 106 or the water pumping channel 108.

[0038] The water pumping device 104 is arranged at the other end of the common channel, and the water pumping device 104 drives the water in the water accumulation container 102 to flow to the common channel, and then to the self-cleaning channel 106 or the water pumping channel 108.

[0039] The self-cleaning channel 106 is connected to the water accumulation container 102 at one end, and the other end of the self-cleaning channel 106 is connected to the spray head 107, and the spray head 107 sprays water to the evaporator 101 for cleaning.

[0040] Figure 2 A first flow diagram of the self-cleaning control method in the embodiment of the present application is shown in the figure, Figure 2 The method can specifically include the following steps.

[0041] Step 201: determining that a self-cleaning condition is met, and controlling the reversing valve to switch the water flow channel to the self-cleaning channel;

[0042] Exemplarily, in some embodiments, the self-cleaning condition includes that the water amount in the water accumulation container during the clothes drying operation is greater than or equal to a preset first water amount threshold; or, a preset self-cleaning time is reached during the clothes drying operation; wherein the self-cleaning time is a first time before the end of the clothes drying operation.

[0043] When the water amount reaches or exceeds the first water amount threshold, there is sufficient water amount and sufficient flushing water pressure when the self-cleaning operation is performed, and the evaporator has a better cleaning effect, so that the influence of insufficient water amount on the self-cleaning effect is avoided, and invalid flushing is avoided. Exemplarily, whether the water amount in the water accumulation container reaches or exceeds the water amount threshold can be judged by detecting the water level line in the water accumulation container.

[0044] When the water amount does not satisfy the self-cleaning condition, the self-cleaning operation can also be triggered by a self-cleaning time. For example, the self-cleaning time is 10 minutes, 5 minutes, 3 minutes, etc. before the end of the drying operation. In this embodiment, when the drying operation runs to the preset self-cleaning time, the self-cleaning program is executed regardless of the water amount stored in the water storage container, so as to ensure that the self-cleaning function can be executed every time the drying process is performed.

[0045] In some embodiments, the self-cleaning condition comprises: the drying operation reaches a preset self-cleaning time, and the water amount stored in the water storage container is greater than or equal to a second water amount threshold; wherein the second water amount threshold is less than the first water amount threshold. In this embodiment, when the drying operation runs to the preset self-cleaning time, and when the water amount stored in the water storage container is greater than or equal to the second water amount threshold, a longer self-cleaning program can be executed, otherwise a shorter self-cleaning program is executed, thereby avoiding the situation that the water amount is insufficient and the self-cleaning program is performed for a long time, and avoiding invalid flushing.

[0046] For example, in some embodiments, the self-cleaning condition further comprises: the clothes treatment apparatus runs a preset drying mode; wherein the drying mode comprises executing the self-cleaning operation. The preset drying mode is a drying mode with a large amount of drying clothes and a long drying time, which usually generates more water and lint, so the self-cleaning operation needs to be executed in time for this kind of drying mode. For short-time drying, fast drying, etc. drying mode, the drying operation time is short, which usually generates less water and lint, so the self-cleaning operation can not be executed in order to avoid invalid flushing.

[0047] Step 202: Start the water pump to execute the self-cleaning operation, and drive the water in the water storage container to be sprayed to the evaporator through the self-cleaning channel.

[0048] For example, in some embodiments, starting the water pump to execute the self-cleaning operation comprises: when the water amount in the water storage container during the drying operation is greater than or equal to a preset first water amount threshold, starting the water pump to execute a self-cleaning operation for a first time length; or, when the drying operation reaches a preset self-cleaning time, starting the water pump to execute a self-cleaning operation for a second time length; wherein the first time length is greater than the second time length.

[0049] Here, when the water amount is greater than or equal to the preset first water amount threshold, it indicates that the water amount is sufficient to execute the self-cleaning operation for a longer time (i.e. the first time length), thereby improving the cleaning effect. When the water amount is less than the preset first water amount threshold, the self-cleaning operation is triggered by the self-cleaning time, which indicates that the water amount is insufficient to execute the self-cleaning operation for a shorter time (i.e. the second time length), thereby improving the flushing efficiency and avoiding invalid flushing.

[0050] For example, in some embodiments, the self-cleaning operation is triggered by the water volume or the time, and the self-cleaning operation is performed for the same length of time.

[0051] For example, in some embodiments, the self-cleaning operation is triggered by the water volume or the time, and the self-cleaning operation is performed for the same length of time. Figure 1 For example, in some embodiments, the self-cleaning operation is triggered by the water volume or the time, and the self-cleaning operation is performed for the same length of time.

[0052] For example, in some embodiments, the self-cleaning operation is triggered by the water volume or the time, and the self-cleaning operation is performed for the same length of time.

[0053] For example, in some embodiments, the self-cleaning operation is triggered by the water volume or the time, and the self-cleaning operation is performed for the same length of time.

[0054] For example, in some embodiments, the self-cleaning operation is triggered by the water volume or the time, and the self-cleaning operation is performed for the same length of time.

[0055] For example, in some embodiments, the self-cleaning operation is triggered by the water volume or the time, and the self-cleaning operation is performed for the same length of time. Figure 3 For example, in some embodiments, the self-cleaning operation is triggered by the water volume or the time, and the self-cleaning operation is performed for the same length of time.

[0056] Step 301: determining that the self-cleaning condition is met, and controlling the reversing valve to switch the water flow channel to the self-cleaning channel;

[0057] Step 302: starting the water pump to perform the self-cleaning operation, and driving the water in the water accumulation container to be sprayed to the evaporator through the self-cleaning channel;

[0058] Step 303: determining that the self-cleaning operation is completed, and closing the water pump;

[0059] Step 304: Determine that the pumping conditions are met, and control the reversing valve to switch the water flow channel to the pumping channel;

[0060] For example, in some embodiments, the water pumping conditions include: the drying operation process reaching a preset water pumping time; wherein the water pumping time is a second time before the drying operation ends; or, determining that the self-cleaning operation is completed.

[0061] In other words, the pumping operation can be triggered by the pumping time. For example, the pumping time can be 30 seconds, 1 minute, or 2 minutes before the end of the drying operation. This forces the pumping operation to be performed before the end of the drying operation, driving the water in the water collection container to the drain container, thus preventing residual sewage in the water collection container from affecting the next self-cleaning effect after the drying operation.

[0062] Alternatively, the pumping operation can be triggered immediately after the self-cleaning process is complete. Lint adhering to the directional control valve affects its operation and shortens its lifespan. Similarly, with the pump shut off, the directional control valve should be switched from the water flow channel to the pumping channel before the pumping operation is complete. This prevents lint and other impurities in the water flow from adhering to the directional control valve during the switching process, thus avoiding blockage and extending its lifespan.

[0063] Step 305: Start the water pump to perform the pumping operation, driving the water in the water accumulation container to be sent into the drainage container through the pumping channel;

[0064] by Figure 1 For example, if the pumping conditions are met, the reversing valve 105 is first controlled to switch the water flow channel to the pumping channel 108. When the pump 104 is working, it drives the water flow to the pumping channel 108 and finally delivers it to the drain container 103. The user can manually remove the drain container 103 and empty the sewage, or the drain container 103 can be connected to the sewage outlet for automatic discharge.

[0065] Step 306: Confirm that the pumping operation is complete and turn off the water pump.

[0066] For example, in some embodiments, after starting the water pump to perform a drainage operation for a preset duration, the drainage operation is determined to be complete; or the drainage operation is determined to be complete when it is detected that there is no water in the water accumulation container or the water volume is less than the lower limit threshold.

[0067] The pumping operation and the self-cleaning operation can be linked together; the pumping operation will be performed after the self-cleaning operation is completed.

[0068] The water pumping operation and the self-cleaning operation can also be separated, that is, the water pumping operation can be performed alone. For example, in some embodiments, the method further comprises: determining that the self-cleaning condition is not met, skipping the self-cleaning operation, that is, skipping steps 301 to 303, and only performing the water pumping operation, that is, performing steps 304 to 306. At this time, the water pumping condition comprises that the drying operation process reaches a preset water pumping time. That is, the water pumping operation is forced to be performed before the drying operation ends, driving the water in the water accumulation container to be pumped into the water drainage container, so as to avoid residual sewage in the water accumulation container after the drying operation ends.

[0069] In order to better reflect the purpose of the present application, on the basis of the above-mentioned embodiments of the present application, the water pumping operation is further exemplified as follows: Figure 4 As shown in the figure, the method specifically comprises:

[0070] Step 401: starting a drying operation;

[0071] Step 402: determining whether the water amount in the water accumulation container is greater than or equal to a preset first water amount threshold; if not, performing step 403; if yes, performing step 404;

[0072] For example, whether the water amount in the water accumulation container reaches or exceeds the first water amount threshold can be determined by detecting the water level line in the water accumulation container. Here, when the water amount reaches or exceeds the water amount threshold, there is sufficient water amount and sufficient flushing water pressure when the self-cleaning operation is performed, and the evaporator has a better cleaning effect.

[0073] Step 403: reaching a preset self-cleaning time, performing step 404; wherein the self-cleaning time is a first time before the drying operation ends;

[0074] That is, the self-cleaning operation is triggered by the water amount or the self-cleaning time, and the water amount is determined first, and then the self-cleaning time is triggered when the water amount does not meet the condition.

[0075] Step 404: starting a water pumping pump to perform a self-cleaning operation, and driving the water in the water accumulation container to be sprayed towards the evaporator through a self-cleaning channel;

[0076] Step 405: determining that the self-cleaning operation is completed, and closing the water pumping pump;

[0077] Step 406: reaching a preset water pumping time, and controlling a reversing valve to switch a water flow channel to a water pumping channel;

[0078] Step 407: starting a water pumping pump to perform a water pumping operation, and driving the water in the water accumulation container to be sent into a water drainage container through a water pumping channel;

[0079] Step 408: determining that the water pumping operation is completed, and closing the water pumping pump.

[0080] To better reflect the purpose of the present application, on the basis of the above-mentioned embodiments of the present application, the extraction operation is further illustrated, as shown in Figure 5 The method specifically includes:

[0081] Step 501: Start the clothes drying operation;

[0082] Step 502: Determine whether the water quantity reaches 1.2L at a time other than 5 minutes before the end of the clothes drying operation; if yes, execute step 503; if no, execute step 504;

[0083] Here, 1.2L is the first water quantity threshold in the embodiments of the present application.

[0084] Step 503: Start the self-cleaning operation and execute for 2 minutes;

[0085] Step 504: Start the self-cleaning operation and execute for 1 minute at 3 minutes before the end of the clothes drying operation;

[0086] Step 505: Start the water pumping operation at 1 minute before the end of the clothes drying operation;

[0087] Step 506: End the clothes drying operation.

[0088] To implement the method of the embodiments of the present application, based on the same inventive concept, the embodiments of the present application further provide a self-cleaning control device, as shown in Figure 6 The device 60 includes:

[0089] A first control unit 601 is configured to determine that a self-cleaning condition is met, and control a reversing valve to switch a water flow channel to a self-cleaning channel;

[0090] A second control unit 602 is configured to start a water pump to execute a self-cleaning operation, and drive water in a water accumulation container to spray towards an evaporator through the self-cleaning channel.

[0091] The determination that the self-cleaning condition is met, the control of the reversing valve to switch the water flow channel to the self-cleaning channel, and the start of the water pump to pump the water in the water accumulation container into the self-cleaning channel for self-cleaning, avoid the adhesion of lint and other impurities in the water flow to the reversing valve during the switching of the reversing valve, block the reversing valve, and prolong the service life of the reversing valve.

[0092] In some embodiments, the self-cleaning condition includes that the water quantity in the water accumulation container during the clothes drying operation is greater than or equal to a preset first water quantity threshold, or that a preset self-cleaning time is reached during the clothes drying operation; wherein the self-cleaning time is a first time before the end of the clothes drying operation.

[0093] When the water amount reaches or exceeds the first water amount threshold, there is sufficient water amount and flushing water pressure when performing the self-cleaning operation, and the evaporator has a better cleaning effect, thereby avoiding the influence of insufficient water amount on the self-cleaning effect and avoiding invalid flushing.

[0094] When the clothes drying operation runs to the preset self-cleaning time, the self-cleaning program is executed regardless of the water amount stored in the water storage container, so as to ensure that the self-cleaning function can be executed in each clothes drying process.

[0095] For example, in some embodiments, the self-cleaning condition further includes that the clothes treatment device runs a preset clothes drying mode; and the clothes drying mode includes executing the self-cleaning operation. The preset clothes drying mode usually generates more water and lint, and thus the self-cleaning operation needs to be executed in time for this type of clothes drying mode. For short-time drying and fast drying, the clothes drying operation time is short, and thus less water and lint are usually generated. In order to avoid invalid flushing, the self-cleaning operation can not be executed.

[0096] In some embodiments, the second control unit 602 is configured to start the water pump to execute a first time length of self-cleaning operation when the water amount in the water storage container is greater than or equal to a preset first water amount threshold during the clothes drying operation.

[0097] Alternatively, the second control unit 602 is configured to start the water pump to execute a second time length of self-cleaning operation when a preset self-cleaning time is reached during the clothes drying operation; and the first time length is greater than the second time length.

[0098] When the water amount is greater than or equal to the preset first water amount threshold, it indicates that the water amount is sufficient to execute the self-cleaning operation for a longer time (i.e., the first time length), thereby improving the cleaning effect. When the water amount is less than the preset first water amount threshold, the self-cleaning operation is triggered by the self-cleaning time, which indicates that the water amount is insufficient to execute the self-cleaning operation for a shorter time (i.e., the second time length), thereby improving the flushing efficiency and avoiding invalid flushing.

[0099] In some embodiments, the second control unit 602 is further configured to determine that the self-cleaning operation is completed, and to turn off the water pump.

[0100] The self-cleaning operation is completed to turn off the water pump, which can prepare for subsequent water pumping operation. Before the water pumping operation is executed, the reversing valve is controlled to switch the water flow channel to the self-cleaning channel, and then the water pump is started to pump the water in the water storage container to the drain container, thereby avoiding that the lint and other impurities in the water flow adhere to the reversing valve during the switching process of the reversing valve, blocking the reversing valve, and prolonging the service life of the reversing valve.

[0101] In some embodiments, the first control unit 601 is further configured to determine that a water pumping condition is met, and control the reversing valve to switch the water flow channel to a water pumping channel.

[0102] The second control unit 602 is further configured to start the water pumping operation of the water pumping device to drive the water in the water storage container to the water draining container through the water pumping channel.

[0103] In some embodiments, the water pumping condition comprises: a drying operation process reaching a preset water pumping time; wherein the water pumping time is a second time before the end of the drying operation; or determining that the self-cleaning operation is completed.

[0104] The water pumping operation is forced to be performed before the end of the drying operation to drive the water in the water storage container to the water draining container, so as to avoid residual sewage in the water storage container after the end of the drying operation.

[0105] In some embodiments, the second control unit 602 is further configured to determine that the water pumping operation is completed, and turn off the water pumping device.

[0106] Based on the hardware implementation of each unit in the above self-cleaning control device, the embodiments of the present application further provide a laundry treating apparatus, as shown in Figure 7 The laundry treating apparatus 70 comprises a processor 701 and a memory 702 configured to store a computer program capable of running on the processor.
