[0042] In order to enable persons skilled in the art to more fully understand the features and technical contents of the embodiments of the application, the implementation of the embodiments of the application is described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the application.

[0043] The cleaning control method disclosed in the application is applied to a clothes processing apparatus. Exemplarily, the clothes processing apparatus can be a washer-dryer or a heat pump clothes dryer, and the present specification takes the heat pump clothes dryer as an example. The drying principle of the heat pump clothes dryer is as follows: the circulating air is dehumidified and heated by the heat pump system to generate dry hot air; the dry hot air is blown into the drying drum, the dry hot air passes through the wet clothes, takes away the water, and becomes warm and humid air; the warm and humid air enters the heat pump system, first passes through the heat exchange assembly (for example, an evaporator) to release water and become dry air; then the dry air is heated into dry hot air again at the heat exchange assembly (for example, a condenser) and enters the drying drum again; thus, the drying of the clothes is realized.

[0044] Since a large amount of lint is generated during the drying process of clothes, the existing clothes dryer usually adds a filter assembly, such as a filter screen, in the air duct for filtering the lint in the drying airflow. In the prior art, when cleaning the lint on the surface of the filter screen component, the lint is separated from the surface of the filter screen and falls into the drain passage by means of water flow flushing, motor-driven filter screen rotation, etc., and then the drain assembly is opened to drain the lint from the drain passage. However, during the process of draining the lint from the drain passage, the lint may stick together and accumulate in the drain passage, which may cause the drain passage to be blocked.

[0045] To this end, the embodiments of the present application provide a cleaning control method of a clothes processing apparatus, which aims to clean the lint on the surface of the filter assembly and drain the lint from the drain passage to avoid the residual of the stuck lint.

[0046] Figure 1 A first flowchart of the cleaning control method in the embodiments of the present application is shown in FIG. 1, which specifically can include the following steps. Figure 1

[0047] Step 101: Control the drain assembly to be in a closed state, and pre-store water in the drain passage.

[0048] In the prior art, the applicant finds that the lint may be blocked in the drain passage, because there is usually no water in the drain passage after the completion of one drainage, which causes a large amount of lint to stick together on the dry passage surface. At this time, it is not easy to disperse the stuck and accumulated lint by water flushing, and if the water is stored in the drain passage in advance, bacteria may grow in the water after a long time, which may infect the washed clothes and affect people's health. To solve this technical problem, the drain assembly is controlled to be in a closed state before cleaning the lint on the filter assembly, and then water is pre-stored in the drain passage, so that the lint falling into the drain passage directly falls into the pre-stored water, and the lint floats or dissolves in the water and is dispersed, thereby avoiding the problem of the lint sticking together in a large amount and the problem of the bacteria growing in the drain passage.

[0049] In some embodiments, the drain assembly can be a drain pump.

[0050] To pre-store water in the drain passage, for example, in some embodiments, the pre-stored water in the drain passage is stopped by stopping the discharge of the condensed water generated by the heat exchange assembly.

[0051] ​Here, the discharge path of the condensed water is connected to or at least partially overlaps with the drain passage of the lint-containing sewage. In the prior art, the heat exchange assembly, such as the evaporator, of the heat pump clothes dryer continuously generates a certain amount of condensed water during the drying process. The condensed water usually flows to the drain assembly and is discharged into the water box structure or outside the clothes dryer. In these embodiments, in order to pre-store water in the drain passage, the drain assembly of the condensed water can be closed to block the discharge path of the condensed water to the water box or outside the clothes dryer, and the condensed water will flow to the drain passage and be temporarily stored, so as to pre-store water in the drain passage.

[0052] In other embodiments, the clothes dryer has a water inlet pipeline connected to an external water source, and water flow can be directly injected into the drain passage through the water outlet of the water inlet pipeline. When the drain assembly is in a closed state, the injected water is temporarily stored in the drain passage, so as to pre-store water in the drain passage.

[0053] In other embodiments, the second water spraying component is controlled to spray water onto the surface of the evaporator to pre-store water in the drain passage.

[0054] Here, the second water spraying component is connected to the water inlet pipeline connected to an external water source, and the drain passage is connected to or partially overlaps with the drain path of the evaporator. The second water spraying component is controlled to spray water onto the surface of the evaporator. When the drain assembly is in a closed state, the water flows into the drain passage after cleaning the surface of the evaporator and is temporarily stored, so as to pre-store water in the drain passage.

[0055] In these embodiments, since the evaporator generates condensed water during the cooling process of the humid air, a small amount of lint will adhere to the surface of the evaporator. Therefore, spraying water onto the surface of the evaporator can flush the lint adhering to the surface of the evaporator, and a small amount of lint will be brought into the drain passage. This small amount of lint is not enough to form a group, so spraying water onto the surface of the evaporator in the closed state of the drain assembly can both pre-store water in the drain passage and clean the surface of the evaporator.

[0056] For example, in some embodiments, controlling the water inlet pipeline to inject water into the drain passage or controlling the second water spraying component to spray water onto the surface of the evaporator includes: determining that the injection or spraying of water lasts for a first preset time length, and controlling the water inlet pipeline or the second water spraying component to stop the injection or spraying of water.

[0057] Here, the duration of the injection or spraying of water can be set to be not more than a preset time, such as 1s, 2s, etc. In this way, under the normal injection or spraying flow, the situation that the pre-stored water overflows from the clothes dryer can be avoided.

[0058] In some embodiments, the method further comprises: determining that the water level in the drain passage exceeds a preset water level value; and controlling the water inlet pipeline or the second water spraying component to stop water injection or water spraying.

[0059] In some embodiments, the method further comprises: determining that the water level in the drain passage exceeds a preset water level value; and controlling the water inlet pipeline or the second water spraying component to stop water injection or water spraying.

[0060] In some embodiments, the method further comprises: determining that the water level in the drain passage exceeds a preset water level value; and controlling the water inlet pipeline or the second water spraying component to stop water injection or water spraying.

[0061] In some embodiments, the method further comprises: determining that the water level in the drain passage exceeds a preset water level value; and controlling the water inlet pipeline or the second water spraying component to stop water injection or water spraying.

[0062] In some embodiments, the preset condition for controlling the laundry treating apparatus to start cleaning the filter assembly can be set according to one or more of the following: time, air outlet temperature and humidity of the drying drum, weight of the laundry, type of the laundry, amount of lint on the surface of the filter screen, coverage area of the lint, fluctuation value of the temperature of the laundry, operating power of the fan, etc.

[0063] In some embodiments, the preset condition can be:

[0064] In some embodiments, the preset condition can be:

[0065] In some embodiments, the preset condition can be:

[0066] In some embodiments, the preset condition can be:

[0067] In some embodiments, the preset condition can be:

[0068] acquiring the temperature of the air duct, and determining that the temperature is greater than a preset temperature value;

[0069] acquiring the temperature fluctuation value of the surface of the clothes, and determining that the temperature fluctuation value is less than a preset temperature fluctuation value;

[0070] acquiring an image of the surface of the filter assembly, and determining that the area covered by the lint is greater than a preset area;

[0071] acquiring the running power of the fan, and determining that the running power of the fan is greater than a preset power.

[0072] Specifically, the first cleaning can be started according to time, for example, once every certain time (40 minutes). The amount of lint is small in the early stage of drying clothes, and the amount of lint is large in the later stage. Therefore, the time of the first cleaning can be relatively delayed, and the subsequent cleaning can be performed at a certain interval. The first cleaning can be controlled according to the outlet air temperature of the drying drum, for example, the surface of the filter assembly is cleaned at temperatures of a ℃, b ℃ and c ℃ respectively. The first cleaning can be controlled according to the humidity of the clothes, for example, the surface of the filter assembly is cleaned at humidities of a %, b % and c % respectively. The first cleaning can be controlled according to the temperature fluctuation of the surface of the clothes, for example, when the temperature fluctuation of the surface is very small, it indicates that the drying enters the later stage, and the surface of the filter assembly is cleaned at this time. The first cleaning can be controlled according to the power of the fan, for example, when the power exceeds a certain set power, it indicates that the air resistance of the filter screen is very large, and the amount of lint attached is large, and cleaning is needed at this time. The first cleaning can be controlled according to the amount of lint or the area covered by the lint on the surface of the filter assembly. When the amount of lint or the area covered by the lint reaches a certain threshold, the surface of the filter assembly is cleaned. The amount of lint or the area covered by the lint can be directly or indirectly recognized by a sensor such as an image sensor, a wind pressure sensor or an infrared sensor.

[0073] Step 102: controlling the first water spraying component to spray water to the surface of the filter assembly to wash the attached lint, so that the lint falls into the drainage channel.

[0074] Here, the first water spraying component sprays water to the surface of the filter assembly, which can directly flush the attached lint on the surface of the filter assembly, and the lint falls off by the impact of water.

[0075] For example, the first water spraying component sprays water to the surface of the filter assembly to wash the attached lint in the second preset time period, and stops spraying water to wash after the second preset time period. The second preset time period refers to the time period sufficient for washing all the attached lint to fall into the drainage channel. The start time of the second preset time period can be earlier than the end time of the first preset time period during which the water inlet pipeline or the second water spraying component injects water into the drainage channel, or later than the end time of the first preset time period.

[0076] The applicant finds that the water pressure of a general household water source varies, and in a use scenario with low water pressure, if the first water spraying component and the second water spraying component are controlled to work at the same time, the impact of the sprayed water flow may not be strong enough to separate the lint from the filter screen and the heat exchange assembly, resulting in poor cleaning effect. Based on this, in the preferred embodiment, the start time of the second preset time period is later than the end time of the first preset time period, so that the first water spraying component is controlled to spray water only after the second water spraying component stops spraying water, thereby avoiding the problem of poor cleaning effect when the water pressure of the water inlet pipeline is insufficient and the two water spraying components spray water at the same time.

[0077] Step 103: Control the drainage assembly to be in a running state, and drain the pre-stored water containing lint in the drainage channel.

[0078] Here, the control of the drainage assembly is switched from the closed state to the running state, and the pre-stored water containing lint in the drainage channel is drained from the drainage channel, so as to achieve the purpose of cleaning the lint attached to the surface of the filter assembly, and the lint will not stick in the drainage channel and the drainage channel will not be blocked due to excessive amount of lint.

[0079] The applicant finds that while draining the water containing lint, if a certain amount of water still flows into the drainage channel, it is beneficial to promote the movement of the lint in the water, which is more conducive to fully draining the lint and preventing residue. Based on this, in some preferred embodiments, the first water spraying component is controlled to spray water to the surface of the filter assembly within a second preset time period; wherein the end time of the second preset time period is later than the start time of the control of the drainage assembly to be in a running state.

[0080] Here, the end time of the second preset time period, i.e. the time when the first water spraying assembly stops spraying water, is later than the start time of the control of the drainage assembly to be in a running state, i.e. the time when the drainage assembly starts to run, so as to ensure that at least part of the time of drainage, there is still a water flow to flush the filter assembly entering the drainage channel, the entering water flow can promote the lint falling in the drainage channel to move to the drainage assembly along the flow direction of the water flow, at this time, the drainage assembly can more fully drain the lint, avoiding the residue of the lint in the drainage channel.

[0081] Here, the execution subject of steps 101 to 103 can be a processor of the clothes treatment device.

[0082] By adopting the technical scheme, when the filter screen cleaning program is started, the drainage assembly such as the drainage pump is controlled to be in a closed state, the second water spraying component is controlled to spray water to the surface of the evaporator first, so that the pre-stored water in the drainage passage of the drainage assembly such as the drainage pump can be stored and cannot be drained, then the first water spraying component is controlled to spray water to the surface of the filter assembly such as the filter screen component to wet the lint, under the action of the water impact force, the lint falls into the drainage passage, and the lint is dispersed in the pre-stored water, so that the large amount of dry lint is prevented from being blocked in the drainage passage in the form of a ball, and when the drainage assembly operates, the pre-stored water containing the lint in the drainage passage is directly drained, so that the lint is prevented from being left in the drainage passage.

[0083] Based on the above embodiments, the application further provides a cleaning control method of a clothes treatment apparatus, Figure 2 FIG. 2 is a second flowchart of the cleaning control method of the clothes treatment apparatus according to an embodiment of the application.

[0084] As shown in Figure 2 The cleaning control method is applied to the clothes treatment apparatus, and specifically can include the following steps.

[0085] Step 201: Start the filter screen cleaning program, control the drainage pump to be in a closed state, and pre-store water in the drainage passage.

[0086] Step 202: Control the first water spraying component to spray water to the surface of the filter screen component to wash the attached lint.

[0087] In some embodiments, the water spraying and washing are used to wet the attached lint on the surface of the filter screen component, so that the weight of the lint increases after being wetted, so that when the motor drives the filter screen component to rotate, all the lint attached to the surface of the filter screen component is thrown out under the action of the centrifugal force.

[0088] For example, the first water spraying component is controlled to spray water to the surface of the filter screen component to wet the attached lint in the first time length, and then the first water spraying component is controlled to stop spraying water. The first time length refers to a time length sufficient to wet all the attached lint.

[0089] Step 203: Control the motor to be in a working state to drive the filter screen component to rotate and throw the lint into the drainage passage.

[0090] Here, the filter screen component is connected to the drainage passage, and by controlling the motor to be in a working state, the filter screen component is driven to be in a rotating state, all the lint attached to the surface of the filter screen component is thrown out to the drainage passage under the action of the centrifugal force, and the purpose of completely cleaning the lint attached to the surface of the filter screen component is achieved.

[0091] For example, the motor is controlled to be in the working state to drive the filter component to rotate in the second time length. After the second time length, the motor is switched from the working state to the shutdown state, so that the filter component stops rotating. The second time length refers to a time length sufficient for the attached lint to be completely thrown out.

[0092] Step 204: Control the drain pump to be in an open state to drain the pre-stored water containing lint in the drain channel.

[0093] By starting the filter cleaning program, the drain pump is controlled to be in the closed state, so that the drain channel of the drain pump can pre-store water and will not be drained. The first water spraying component sprays water to the surface of the filter component to wet the lint. The filter is rotated, and the lint is thrown to the drain channel under the action of centrifugal force. The lint is dispersed in the pre-stored water, avoiding the blockage of a large amount of dry lint in the form of a ball in the drain channel. When the drain pump is opened, the pre-stored water containing lint in the drain channel is directly drained.

[0094] Based on the above embodiment, the cleaning control method is proposed based on the execution of the drying program by the laundry treatment device, Figure 3 FIG. 3 is a third flowchart of the cleaning control method in the embodiments of the present application.

[0095] As shown in Figure 3 The cleaning control method is applied to the laundry treatment device. The cleaning control method can specifically include the following steps.

[0096] Step 301: Determine that the laundry treatment device is about to execute a drying process, and control the first water spraying component to spray water to the surface of the filter assembly for flushing.

[0097] Here, the first water spraying component sprays water to the surface of the filter assembly before the drying process starts. At this time, the air volume in the air duct of the dryer is 0. Flushing the surface of the filter assembly before the drying process starts can effectively remove the residual lint that may exist after the last filter cleaning, so that the resistance of the filter to the airflow is minimized at the start of drying. The water spraying flushing process can be set to a preset time length, for example, 5s, 10s, etc. The time length can be a fixed time length set in advance or can be determined according to the weight, material, etc. of the laundry.

[0098] Step 302: Control the drain assembly to be in a running state to drain the water in the drain channel.

[0099] Here, since there is little residual lint on the filter assembly before drying, it is difficult to produce adhesion and the like, so no pre-stored water is needed before flushing. Only the drain assembly needs to be opened to drain water when the set time or water level is reached.

[0100] Step 303: Control the laundry treatment device to execute a drying process.

[0101] Here, the drainage assembly can be controlled to be in a closed state or in a running state. During the drying process, the heat pump system continuously generates condensate water, so the drainage assembly in the running state can continuously drain the condensate water. In order to save energy, the drainage assembly can also be set to open and close intermittently. These are reasonable settings that can be made according to actual needs, and the present embodiment does not limit them.

[0102] Step 304: Determine whether to start the filter screen cleaning program; if yes, execute step 305.

[0103] The filter screen cleaning program is started according to the filter screen cleaning start condition. The filter screen cleaning start condition: one or more of the time, the dry drum outlet air temperature and humidity, the weight of the clothes, the type of clothes, the amount of lint on the surface of the filter screen, the coverage area of the lint, the fluctuation value of the surface temperature of the clothes, the running power of the fan, etc. can be set.

[0104] Step 305: Control the drainage pump to be in a closed state, control the second water spraying component to spray water to the surface of the evaporator within a preset time period, and pre-store water in the drainage channel.

[0105] Step 306: Control the second water spraying component to stop spraying water after the preset time period.

[0106] That is, within the preset time period, the second water spraying component is controlled to spray water to the surface of the evaporator, so that the pre-stored water in the drainage channel is sufficient to drain the falling lint and will not overflow. After the preset time period, the second water spraying component is controlled to stop spraying water to prevent water overflow in the drainage channel.

[0107] Step 307: Control the first water spraying component to spray water to the surface of the filter screen component to wet the attached lint within a first time period.

[0108] Here, the lint is wetted in order to subsequently rotate the filter screen component under the action of centrifugal force, so that all the lint attached to the surface of the filter screen component is thrown out, that is, the surface of the filter screen component is completely cleaned.

[0109] The first time period refers to the time period sufficient to wet all the attached lint.

[0110] Step 308: Control the motor to be in a working state to drive the filter screen component to rotate and throw the wet lint into the drainage channel within a second time period.

[0111] The second time period refers to the time period sufficient to throw out all the attached lint.

[0112] Step 309: Control the drainage pump to be in a running state to drain the pre-stored water containing the lint in the drainage channel.

[0113] Step 310: The filter cleaning program is completed. Control the first water spraying component to stop spraying water and control the motor to the off state.

[0114] Step 311: Control the garment handling device to complete the drying process.

[0115] This application describes a method for cleaning lint adhering to the surface of a filter element during the drying process of a clothing processing device. This reduces the airflow resistance of the filter element during the drying process, allowing all the hot air in the airflow to be delivered into the drying drum for drying clothes, thereby increasing the drying rate and shortening the drying time.

[0116] Using the above technical solution, the filter cleaning program is started, and the drain pump is kept in the off state. First, the second water spray component is controlled to spray water onto the surface of the evaporator, so that water can be pre-stored in the drain channel of the drain pump and will not be discharged. Then, the first water spray component is controlled to spray water onto the surface of the filter component to wet the lint. The filter is rotated, and under the action of centrifugal force, the lint is thrown into the drain channel. The lint will dissolve in the pre-stored water and be dispersed, avoiding a large amount of dry lint from clumping up and blocking the drain channel. When the drain pump is turned on, the pre-stored water containing lint in the drain channel is discharged directly.

[0117] To implement the method of the embodiments of this application, based on the same inventive concept, a cleaning control device is also provided in the embodiments of this application. Figure 4 This is a schematic diagram of the composition of the cleaning control device in the embodiments of this application, such as... Figure 4 As shown, the cleaning control device is applied to a garment processing equipment, and the cleaning control device 40 may specifically include:

[0118] The first control unit 401 is used to control the drainage assembly to be in a closed state and to pre-store water in the drainage channel;

[0119] The second control unit 402 is used to control the first water spray component to spray water onto the surface of the filter assembly to wash away the attached lint, so that the lint falls into the drainage channel, wherein the filter assembly is used to filter the lint in the airflow.

[0120] The first control unit 401 is also used to control the drainage assembly to be in operation and to discharge the pre-stored water containing lint from the drainage channel.

[0121] Using the above technical solution, the filter cleaning program is started. By controlling the drainage component, such as the drainage pump, to be in a closed state, water can be pre-stored in the drainage channel of the drainage component, such as the drainage pump, and will not be discharged. In this way, the lint attached to the surface of the filter component, such as the filter screen component, that falls into the drainage channel will dissolve in the pre-stored water and be dispersed, thus avoiding a large amount of dry lint from clumping up and clogging the drainage channel. When the drainage component, such as the drainage pump, is turned on, the pre-stored water containing lint in the drainage channel is directly discharged.
