Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, specifically relating to a clothing processing device and its control method and storage medium. Background Technology

[0002] During the drying process of clothes handling equipment such as washing machines and washer-dryer combos, condensation is generated inside the equipment. This condensation accumulates in the tray. If the water level in the tray becomes too high, the drain pump will activate to drain the condensation into the drain box or to the outside of the equipment. However, during the drying process, the circulating air inside the equipment can tilt the water level in the tray, causing the water level at the drain pump inlet to be very low. Alternatively, if the water level drops during the previous draining process and falls below the drain pump inlet, air can enter the drain pump. These situations can all cause air entrapment in the drain pump, preventing it from functioning properly and completing the drainage process, ultimately causing the clothes handling equipment to shut down due to abnormal drainage. Summary of the Invention

[0003] In view of the technical problem that drainage pumps are prone to air entrapment, which can cause equipment shutdown, this application proposes a garment processing device, its control method, and a storage medium. The device first controls the drainage pump to discharge into a first pipeline, and then switches to discharge into a second pipeline for drainage. By changing the drainage route, any air that may be present in the drainage pump can be discharged into the first pipeline, eliminating the air entrapment problem. Then, the device switches to the second pipeline to discharge water, reducing the likelihood of the garment processing device shutting down due to air entrapment in the drainage pump during the drying process.

[0005] In response to the discharge command, the drain pump is controlled to discharge into the first pipeline for a first preset time;

[0006] Once the first preset time is reached, the drain pump is controlled to discharge water into the second pipeline. Both the first pipeline and the second pipeline are connected to the drain pump, and the second pipeline is used to drain water from the clothing processing equipment.

[0012] In some embodiments of this application, the method further includes:

[0013] Once the shutdown time of the drainage pump reaches a third preset time, the connection between the drainage pump and the first pipeline is shut off.

[0014] In some embodiments of this application, controlling the drain pump to discharge into the second pipeline includes:

[0015] The control reversing valve connects the drain pump to the second pipeline. After waiting for a fourth preset time, the control drain pump starts to discharge.

[0016] In response to a stop discharge command, the drain pump is controlled to stop operating.

[0017] In some embodiments of this application, controlling the drainage pump to stop operating in response to a stop discharge command includes:

[0018] If the water level of condensate in the collection pan is detected to be less than or equal to a preset water level, a stop discharge command is triggered, controlling the drain pump to stop working; the preset water level is used to characterize the highest water level at which the drain pump can generate trapped air.

[0027] In this embodiment, the drain pump is first controlled to discharge into the first pipeline, and then switched to discharge into the second pipeline used for draining condensate. By changing the drainage route, any air that may be present in the drain pump can be expelled into the first pipeline, eliminating air entrapment in the drain pump. Then, switching to the second pipeline to discharge water ensures that there is no air entrapment in the drain pump, allowing it to pump water normally and successfully drain the water. This improves drainage efficiency, reduces the likelihood of the garment processing equipment stopping due to air entrapment in the drain pump during the drying process, and enhances the product reliability of the garment processing equipment.

[0037] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0038] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0039] Washing machines, washer-dryer combos, and other garment processing equipment have the function of drying the load. In condenser or heat pump garment processing equipment, hot air blows across the load to remove moisture. When the air containing a large amount of water vapor passes through the heat exchanger, the water is separated and becomes condensate, which collects in a condensate tray. In condenser garment processing equipment, the heat exchanger can be a condenser, while in heat pump garment processing equipment, the heat exchanger can be an evaporator.

[0040] Once the water collection tray is full, a drain pump is needed to drain the condensate from the tray, which can then be discharged outside the garment processing equipment. Alternatively, the condensate can be drained into a drain box within the garment processing equipment for temporary storage. When the drain box is also full, the water in the drain box will be automatically drained outside the garment processing equipment, or the user can empty the water from the drain box.

[0041] In related technologies, during the drying process of clothing processing equipment, the circulating air passes through the water collection tray. The airflow causes the water level in the tray to tilt, lowering the water level near the drain pump inlet. Alternatively, when the water collection tray is full of condensate, the drain pump needs to drain it, causing the water level to drop continuously. In these cases, if the water level drops to a point where it cannot submerge the drain pump inlet, continued pumping will create air trapping inside the pump and in the piping connected to its outlet. This air trapping prevents the drain pump from properly transferring water from the inlet to the outlet, thus hindering drainage. In this situation, the clothing processing equipment detects the drainage abnormality and shuts down, preventing the drying process from completing.

[0042] Based on this, embodiments of this application provide a control method for a garment processing device. In response to a discharge command, the method controls a drain pump to discharge water into a first pipeline for a first preset time. Once the first preset time is determined to have elapsed, the method controls the drain pump to discharge water into a second pipeline. Both the first and second pipelines are connected to the drain pump, and the second pipeline is used to discharge water from the garment processing device.

[0043] In this method, when it is necessary to drain condensate from the collection tray, the drain pump is first controlled to discharge into the first pipeline, and then switched to the second pipeline for draining condensate. By changing the drainage route, any air that may be trapped in the drain pump can be expelled into the first pipeline, eliminating air entrapment. Then, switching to the second pipeline to drain the condensate ensures that there is no trapped air in the drain pump, allowing it to pump water normally and successfully drain the condensate from the collection tray. This improves drainage efficiency, reduces the likelihood of machine shutdowns caused by air entrapment in the drain pump during the drying process, and enhances the reliability of the clothing processing equipment.

[0044] The control method for clothing processing equipment provided in this application is applicable to clothing processing equipment with drying functions, such as dryers and washer-dryer combos, and is suitable for both condenser and heat pump clothing processing equipment. Except for applications requiring condensate drainage, the control method provided in this application is applicable to any other scenario where water needs to be drained from the clothing processing equipment. The following detailed description, in conjunction with the accompanying drawings, describes a clothing processing device, its control method, and a storage medium provided in this application.

[0045] The structure of the garment processing equipment provided in this application embodiment is shown in [reference]. Figure 1The diagram shows the structure of a garment processing device, which includes a controller 1, a drain pump 2, a first pipeline 3, a second pipeline 4, and a reversing valve 5. The drain pump 2 is connected to the reversing valve 5 via a pipeline, and the reversing valve 5 is connected to both the first pipeline 3 and the second pipeline 4. The controller 1 is communicatively connected to the drain pump 2 and the reversing valve 5. The second pipeline 4 is used to drain water from the garment processing device. One end of the first pipeline 3 is connected to the reversing valve 5, while the other end is open and not connected to any other structure.

[0046] The aforementioned drain pump 2 is connected to the first pipeline 3 and the second pipeline 4 respectively, and the reversing valve 5 can switch the flow direction of the fluid between the first pipeline 3 and the second pipeline 4. The communication connection between the controller 1 and the drain pump 2 and the reversing valve 5 can be a wired connection or a wireless connection. Figure 1 The communication connection is shown using dashed lines.

[0047] In some embodiments, the garment processing equipment may further include a water collection tray and a drain box. The water collection tray is used to collect condensate generated during the drying process. After the water collection tray is full, some or all of the condensate in the water collection tray can be transferred to the drain box for temporary storage. The second pipe 4 can be connected to the water collection tray and the drain box respectively, and the condensate in the water collection tray can be discharged to the drain box along the second pipe 4.

[0048] In other embodiments, the second pipe 4 can be connected to the outside of the clothing processing equipment. The second pipe 4 is connected to the water collection tray in the clothing processing equipment, and the condensate in the water collection tray can be discharged to the outside of the clothing processing equipment along the second pipe 4.

[0049] The first pipe 3 can be any pipe in the garment processing equipment that is connected to the drain pump 2, except for the second pipe 4. As an example, the garment processing equipment includes a heat exchanger and an assembly for automatically cleaning the heat exchanger. The first pipe 3 can be a self-cleaning pipe for cleaning the heat exchanger, with one end connected to a reversing valve 5 and the other end open. During heat exchanger cleaning, water flows from the drain pump to the end of the self-cleaning pipe connected to the reversing valve 5, flows through the self-cleaning pipe, exits from the open end, and sprays onto the heat exchanger, thus rinsing it.

[0050] like Figure 2In the schematic diagram of the garment processing equipment shown, both the first pipe 3 and the second pipe 4 are connected to the reversing valve 5, and the drain pump 2 is connected to the reversing valve 5 via a pipe. When the reversing valve 5 connects the first pipe 3 and the drain pump 2, the drain pump 2 can transport the condensate in the collection pan to the first pipe 3, and finally spray it onto the heat exchanger from the nozzle above the heat exchanger, thus cleaning the heat exchanger. When the reversing valve 5 connects the second pipe 4 and the drain pump 2, the drain pump 2 can transport the condensate in the collection pan to the second pipe 4, and finally input it into the drain box, or output it to the outside of the garment processing equipment.

[0051] In some embodiments, when the reversing valve 5 connects the drain pump 2 and the first pipeline 3, the second pipeline 4 is not connected to the drain pump 2. Conversely, when the reversing valve 5 connects the drain pump 2 and the second pipeline 4, the first pipeline 3 is not connected to the drain pump 2.

[0052] For clothing processing equipment that includes other pipes connected to the drain pump 2 in addition to the second pipe 4 used to drain water from the collection pan, the control method provided in the embodiments of this application can be used to solve the technical problem of the drain pump 2 shutting down due to air entrapment.

[0053] Based on the structure of the aforementioned garment processing equipment, this application proposes a control method for the garment processing equipment. (See attached document.) Figure 3 The flowchart shows a control method for a garment processing device. This method can be applied to a garment processing device with the above-described structure. The method specifically includes the following steps 101-102.

[0054] Step 101: In response to the discharge command, control the drain pump to discharge into the first pipeline for a first preset time.

[0055] Step 102: Once the first preset time has elapsed, control the drain pump to discharge water into the second pipeline. Both the first and second pipelines are connected to the drain pump. The second pipeline is used to drain water from the clothing processing equipment.

[0056] The executing entity of this application embodiment may be a having Figure 1 The garment processing equipment shown in the diagram may include, but is not limited to, dryers, washer-dryer combos, etc.

[0057] The discharge command is an instruction to drain water from the garment processing equipment. For example, it could be an instruction to drain water from the collection tray in the garment processing equipment. This discharge command could be triggered when the garment processing equipment detects that the condensate in the collection tray meets preset drainage conditions. The preset drainage conditions could be that the interval since the last drainage has reached a set time, such as 20 minutes or 30 minutes. Alternatively, the garment processing equipment could be equipped with a sensor to detect the water level in the collection tray. When the water level in the collection tray reaches a set level, the preset drainage conditions are determined to be met. Alternatively, the garment processing equipment could be equipped with a float assembly. When the surface of the condensate in the collection tray comes into contact with the float assembly, the float assembly will float due to buoyancy. If the water level drops to a point where the surface no longer contacts the float assembly, the float assembly will fall back down. The garment processing equipment determines that the preset drainage conditions are met when it detects that the float assembly is floating.

[0058] In this embodiment, after the discharge command is triggered, the garment processing equipment does not immediately control the drain pump to drain water into the second pipe used for discharging water. Instead, it first controls the drain pump to discharge into the first pipe, which can be any pipe connected to the drain pump other than the second pipe. Discharging into the first pipe first allows any trapped air in the drain pump to be expelled into the first pipe. When switching to discharge into the second pipe, the problem of trapped air in the drain pump is eliminated, allowing for normal water pumping and discharge along the second pipe. This improves water discharge efficiency, effectively reduces the possibility of abnormal drainage and subsequent shutdowns caused by trapped air in the drain pump during water discharge, and enhances the stability and reliability of the garment processing equipment.

[0059] In some embodiments of this application, after a discharge command is triggered, in response to the command, the reversing valve can be first controlled to connect the drain pump and the first pipeline, and then the drain pump can be started to discharge. Once the discharge time of the drain pump reaches a first preset time, the drain pump can be controlled to shut down. The first preset time can be, but is not limited to, 1s, 2s, or 3s.

[0060] When the preset drainage conditions are met and water needs to be discharged, the drainage pump is connected to the first pipeline. After the drainage pump starts working, it can discharge the fluid inside the drainage pump and in the pipeline between the drainage pump and the first pipeline into the first pipeline. At this time, the fluid inside the drainage pump and in the pipeline between the drainage pump and the first pipeline may include water and / or air. If air is present, it can be discharged into the first pipeline, thereby preventing this air from affecting the subsequent water discharge.

[0061] In some embodiments of this application, controlling the drain pump to discharge into the first pipeline may specifically include controlling a reversing valve to connect the drain pump and the first pipeline, waiting for a second preset time, and then controlling the drain pump to start discharging. The second preset time is greater than or equal to the action time required for the reversing valve to switch.

[0062] In these embodiments, the drain pump is connected to a reversing valve via a pipeline. The reversing valve is connected to a first pipeline and a second pipeline, and is used to switch the flow direction of the fluid between the first and second pipelines. When a discharge command is triggered, the reversing valve is controlled to switch the flow direction of the fluid from the second pipeline to the first pipeline, thereby connecting the drain pump to the first pipeline. A timer starts from the moment the reversing valve is controlled, and after the timer reaches a second preset duration, the drain pump is then controlled to start discharging.

[0063] The aforementioned second preset duration can be, but is not limited to, 3s, 3.5s, 4s, etc. The second preset duration is greater than or equal to the action time required for the directional valve to switch. Therefore, sufficient action time is reserved for the directional valve before starting the drain pump to ensure that the directional valve switches to the correct position when the drain pump is started, avoiding damage to the directional valve due to fluid impact if the drain pump is started before the directional valve has switched to the correct position. After the directional valve has switched to the correct position, the drain pump is started, allowing the fluid inside the drain pump and the fluid remaining in the pipeline between the drain pump and the directional valve to be discharged into the first pipeline.

[0064] Because the water level may drop below the drain pump's inlet during the final stage of the previous discharge, while the pump continues to pump, air may remain inside the pump and in the piping between the pump and the reversing valve after the previous discharge. Discharging into the first pipe during this second discharge removes this air from the pump and the piping between it and the reversing valve, reducing the probability of air trapped inside the pump and in the piping. This improves the discharge efficiency of subsequent pumps and reduces discharge anomalies caused by air trapped in the pump.

[0065] In some embodiments of this application, after the discharge command is triggered, the drain pump is first controlled to discharge into the first pipeline for a first preset time according to the above embodiments, and then the drain pump is turned off. When it is determined that the shutdown time of the drain pump has reached a third preset time, the passage between the drain pump and the first pipeline is cut off.

[0066] The aforementioned third preset time may include, but is not limited to, 3s, 4s, or 5s. After the drain pump is turned off, the fluid in the pipeline between the drain pump and the reversing valve will still flow towards the first pipeline due to inertia. Therefore, delaying the closing of the passage between the drain pump and the first pipeline by the third preset time after turning off the drain pump allows as much fluid as possible to flow into the first pipeline from the pipeline between the drain pump and the reversing valve, thereby increasing the probability of venting air from the drain pump and the reversing valve into the first pipeline. Moreover, when the passage between the drain pump and the first pipeline is closed, the fluid in the pipeline between the drain pump and the reversing valve will flow back under the action of force. Delaying the closing of the passage between the drain pump and the first pipeline by the third preset time reduces the possibility of air flowing back into the pipeline between the drain pump and the reversing valve or back into the drain pump.

[0067] In some embodiments of this application, after shutting off the passage between the drainage pump and the first pipeline, controlling the drainage pump to discharge into the second pipeline may specifically include controlling the reversing valve to connect the drainage pump and the second pipeline, waiting for a fourth preset time, and controlling the drainage pump to start discharging; in response to a stop discharging command, controlling the drainage pump to stop working.

[0068] The aforementioned fourth preset time can be, but is not limited to, 3s, 4s, or 5s. This fourth preset time can be greater than or equal to the action time required for the directional valve to switch. Therefore, sufficient action time is reserved for the directional valve before starting the drain pump, ensuring that the directional valve switches to the correct position when the drain pump is started. This avoids damage to the directional valve due to fluid impact if the drain pump is started before the directional valve has switched to the correct position. After the directional valve has switched to the correct position, the drain pump is started to discharge the water. Because the first preset time is used to discharge into the first pipeline before discharging into the second pipeline, the probability of air trapped inside the drain pump and in the pipeline between the drain pump and the directional valve is very small when discharging into the second pipeline. The possibility of abnormal discharge due to air trapped is very small, effectively reducing the occurrence of equipment shutdowns caused by air trapped in the drain pump.

[0069] In some embodiments of this application, the aforementioned stop-discharge command may be triggered by detecting that the water level in the laundry processing device (or water collection pan) is less than or equal to a preset water level. In response to this stop-discharge command, the drain pump is controlled to stop operating. The preset water level is used to characterize the highest water level at which the drain pump can trap air.

[0070] A water level sensor can be used to detect the water level. The preset water level can be the water level that exceeds the highest point of the drain pump's inlet. As an example, the preset water level can be the water level that just reaches the highest point of the drain pump's inlet. If the water level is lower than the highest point of the drain pump's inlet, the water will not completely submerge the inlet, and air can easily enter the drain pump when it is pumping water.

[0071] When the water level is detected to be less than or equal to the preset water level, the drainage pump is controlled to stop working. This prevents the water level from continuing to drop and avoids the situation where the drainage pump continues to work after the water level has fallen below the highest point of the drainage pump inlet. This reduces the occurrence of air entering the drainage pump and effectively reduces the occurrence of equipment shutdown due to air trapped in the drainage pump.

[0072] In some embodiments of this application, the first pipeline can be a self-cleaning pipeline for cleaning the heat exchanger in the garment processing equipment. By reusing the original self-cleaning pipeline in the garment processing equipment, water can be discharged into the self-cleaning pipeline before it is discharged, so as to discharge any air that may be present in the drain pump and the pipeline between the drain pump and the reversing valve into the self-cleaning pipeline. Then, the second pipeline is switched to discharge the water. This can reduce the occurrence of abnormal discharge due to air trapped in the drain pump, reduce equipment downtime, and improve the stability and reliability of equipment operation.

[0073] In some embodiments of this application, one end of the first pipeline is connected to the drain pump, while the other end is open and not connected to any other structure. Because the other end of the first pipeline is open, it cannot be sealed by water or anything else and is open to air. Thus, when a discharge command is triggered, air is first discharged into the first pipeline, allowing any air that may be present inside the drain pump or between the drain pump and the reversing valve to be expelled through the first pipeline, preventing air from being trapped within it. This effectively solves the problem of air trapped in the drain pump and the pipeline between the drain pump and the reversing valve, improving the pumping efficiency of the drain pump and reducing the occurrence of abnormal drainage and subsequent shutdowns due to air trapping.

[0074] To facilitate understanding of the control process in the embodiments of this application, the following description is provided in conjunction with the accompanying drawings. Figure 4 As shown, the control process includes the following steps:

[0075] S1: The water level in the collection pan is detected to meet the preset drainage conditions, triggering a discharge command.

[0076] S2: Control the reversing valve to connect the drain pump to the first pipeline, wait for the second preset time, and then control the drain pump to start discharging.

[0077] S3: Once the drainage pump's discharge time reaches the first preset time, control the drainage pump to shut down.

[0078] S4: Determine that the shutdown time of the drain pump has reached the third preset time, shut off the passage between the drain pump and the first pipeline, and connect the passage between the drain pump and the second pipeline.

[0079] S5: Wait for the fourth preset time, then start the drain pump to discharge.

[0080] S6: In response to a stop discharge command, controls the drain pump to stop operating.

[0081] Figure 4 The control flow shown is only an example, and the specific control flow can be determined according to the above embodiments.

[0082] In this embodiment, the drain pump is first controlled to discharge into the first pipeline, and then switched to discharge into the second pipeline used for draining condensate. By changing the drainage route, any air that may be present in the drain pump can be expelled into the first pipeline, eliminating air trapping in the drain pump. Then, switching to the second pipeline to discharge the condensate ensures that there is no air trapping in the drain pump, allowing it to pump water normally and successfully drain the water. This improves drainage efficiency, reduces the likelihood of the garment processing equipment stopping due to air trapping in the drain pump during the drying process, and enhances the product reliability of the garment processing equipment.

[0083] Some embodiments of this application also provide a garment processing device, see [link to relevant documentation] Figure 1 The structure of the garment processing equipment shown includes a controller 1, a drain pump 2, a first pipeline 3, a second pipeline 4, and a reversing valve 5. The drain pump 2 is connected to the reversing valve 5 through the pipeline, and the reversing valve 5 is connected to the first pipeline 3 and the second pipeline 4 respectively. The controller 1 is communicatively connected to the drain pump 2 and the reversing valve 5. The second pipeline 4 is used to drain water from the garment processing equipment.

[0084] Controller 1 is used to control drain pump 2 to discharge water into first pipe 3 for a first preset time in response to a discharge command; and to control drain pump 2 to discharge water into second pipe 4 when the first preset time is reached.

[0085] Controller 1 is used to control the reversing valve 5 to connect the drain pump 2 and the first pipeline 3, start the drain pump 2 to discharge; and control the drain pump 2 to shut down when the discharge time of the drain pump 2 reaches the first preset time.

[0086] Controller 1 is used to control the reversing valve 5 to connect the drain pump 2 and the first pipeline 3, wait for a second preset time, and control the drain pump 2 to start discharging. The second preset time is greater than or equal to the action time required for the reversing valve 5 to switch.

[0087] Controller 1 is used to determine when the shutdown time of drain pump 2 reaches a third preset time, thereby shutting off the passage between drain pump 2 and first pipeline 3.

[0088] Controller 1 is used to control the reversing valve 5 to connect the drain pump 2 and the second pipeline 4, wait for a fourth preset time, and control the drain pump 2 to start discharging; in response to the stop discharging command, control the drain pump 2 to stop working.
