Description

A washing device and its control method Technical Field

[0001] This invention belongs to the field of washing equipment technology, specifically, it relates to a washing device and its control method. Background Technology

[0002] As shown in Figure 1, a conventional pulsator washing machine has an outer tub 1 and an inner tub 2. A rotatable pulsator 3 is installed at the bottom of the inner tub 2 to agitate the clothes and wash water. During the washing process, the clothes rub against the pulsator 3 at the bottom of the inner tub 2, producing lint. If this lint is dispersed in the wash water, it will adhere to the surface of the clothes after washing, affecting the cleaning effect. Therefore, a water channel filter 4 is installed on the wall of the inner tub 2. During the washing process, the wash water enters the water channel filter 4, flows through the filter screen, and is discharged, thus collecting the lint in the water to the water channel filter 4 and reducing the amount of lint dispersed in the water.

[0003] However, for top-loading washing machines, the volume of the inner tub 2 determines the maximum washing capacity. The installation of the water filter 4 inevitably occupies space inside the inner tub 2 or between the inner tub 2 and the outer tub 1. Therefore, given a fixed overall size of the washing machine, this reduces the volume of the inner tub 2, affecting the maximum washing capacity. Furthermore, the water filter 4 requires regular manual cleaning of lint by the user. This cleaning process necessitates disassembling and reinstalling the water filter 4, which is inconvenient for users. Moreover, if the user forgets to clean the lint, it will affect the filtration effect when using the top-loading washing machine subsequently.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The first aspect is to provide a washing device that can automatically clean the lint accumulated in the filter device during the washing program, thus ensuring the filtration effect. Furthermore, the program control can prevent the lint cleaning process from conflicting with the filtration process.

[0006] A second aspect of the present invention provides a washing device having a filter with a flexible filter assembly, which can improve the efficiency of lint removal.

[0007] The third aspect of the present invention provides a control method for the above-mentioned washing equipment, which uses program control to prevent the lint removal process and the filtration process from being executed simultaneously, thereby avoiding conflicts and affecting the operating effect.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] A washing device, comprising:

[0010] Water bucket;

[0011] A filtration device having an inlet chamber connected to a water tank and a filter chamber connected to the inlet chamber via a filter assembly;

[0012] A drainage device is connected to the water inlet chamber of the filter device. The drainage device performs a drainage action, and the water in the water tank flows through the water inlet chamber of the filter device, carrying the lint and being discharged, triggering the filter device to perform a lint cleaning action.

[0013] The control system controls the drainage device to perform a drainage action and controls the filtration device to perform a filtration action, wherein the drainage action and the filtration action are not performed simultaneously.

[0014] Furthermore, the filter device has a housing, and the filter assembly is disposed inside the housing, dividing the internal space of the housing into an inlet chamber and a filter chamber located on both sides of the filter assembly;

[0015] The filter assembly is made of a material capable of elastic deformation; the filter device performs a filtration action, and the filter assembly bends toward the side where the water filter chamber is located; the filter device performs a lint removal action, and the filter assembly bends toward the side where the water inlet chamber is located;

[0016] Preferably, the filtration device is located outside the water tank.

[0017] A control method for the washing equipment described above, wherein the control system controls either the drainage action or the filtration action to be performed, or controls neither the drainage action nor the filtration action to be performed.

[0018] Furthermore, if the other action is not currently being performed, the action to be started can be started before the washing equipment starts either the drainage action or the filtration action;

[0019] Preferably, the drainage action can be initiated before the washing device starts the drainage action if the filtration action is not currently being performed;

[0020] The drainage device performs a drainage action, which triggers the filter device to perform a lint cleaning action.

[0021] Furthermore, once the washing device initiates either the drainage or filtration action, the other action cannot be selected.

[0022] Preferably, when the washing equipment runs the washing program to the drainage stage, the drainage device is controlled to perform the drainage action; at the same time, the filtration action is disabled.

[0023] Furthermore, if the washing device is performing another action before starting either the drainage or filtration action, the execution of the other action will be interrupted, and the action to be started will be executed first.

[0024] Preferably, if a filtration operation is in progress before the washing device performs the drainage operation, the filtration operation is interrupted, and the drainage device is controlled to perform the drainage operation first; after the drainage operation is completed, the filtration device continues to perform the filtration operation.

[0025] Furthermore, after the filtration action is interrupted, the drainage device continues to perform the drainage action for a set time, and then the drainage action ends.

[0026] Alternatively, after interrupting the filtration action, the drainage device continues to perform the drainage action, and when it is determined that the drainage volume of this drainage action has reached the set water volume, the drainage action ends.

[0027] Furthermore, during or after the drainage action is performed by the drainage device, the washing equipment replenishes water into the water tank.

[0028] Preferably, the filtration device continues to perform the filtration operation after the drainage operation is completed and the water is replenished.

[0029] Furthermore, if the washing device is performing another action before initiating either the drainage or filtration action, the action to be initiated will not be executed.

[0030] Furthermore, the washing equipment waits for another action being performed to stop before executing the action to be started.

[0031] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0032] In this invention, the washing equipment can trigger the filter device to clean lint using the drainage action of the drainage device. In other words, the lint cleaning process of the filter device can be completed using the existing control logic of the washing equipment, eliminating the need for the user to manually clean the lint, simplifying the user's operation, and preventing the filter device from being clogged by lint and affecting the filtration function.

[0033] In this invention, the filter device is located outside the water tank. Compared with the traditional pulsator washing machine that sets the water channel filter on the inner wall of the tub, it does not occupy the space inside the tub, which is conducive to increasing the washing capacity. At the same time, it also avoids the problem of dirt and grime easily accumulating in local areas of the water channel, and improves the cleanliness of the space inside the tub.

[0034] In this invention, the filtration device has a filter assembly made of a material capable of elastic deformation. When performing filtration and lint cleaning operations, the bending deformation direction of the filter assembly is different. The elastic deformation of the filter assembly can be used to peel off the lint attached to the surface of the filter assembly, thereby improving the lint cleaning efficiency.

[0035] In this invention, the control system of the washing equipment controls the drainage action and the filtration action to be executed at different times. This avoids the problem of conflict caused by the simultaneous occurrence of the washing water filtration process and the lint cleaning process in the filtration device, thus ensuring the filtration effect and the lint cleaning effect.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0053] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0054] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0055] The present invention provides a washing device and a control method thereof. The washing device may be a household appliance with clothing cleaning function, such as a washing machine, a washer-dryer combo, or a garment care machine.

[0056] Specifically, as shown in Figures 2 to 7, in an embodiment of the present invention, the washing device has a water tank 100 for holding washing water, a filter device 500 connected to the water tank 100 for filtering the washing water, and a drain device for controlling the water tank 100 to drain water outward.

[0057] In one specific embodiment, the filter device 500 is disposed outside the water tank 100, and has an inlet chamber 511 communicating with the water tank 100, and a filter chamber 512 communicating with the inlet chamber 511 through a filter assembly 520. The water to be filtered enters the inlet chamber 511, and the filtered water passes through the filter assembly 520 into the filter chamber 512, where lint is collected.

[0058] The drainage device is connected to the water inlet chamber 511 of the filter device 500. When the drainage device performs the drainage action, the water in the water tank 100 is discharged outward to the water inlet chamber 511 of the filter device 500, and after flowing through the water inlet chamber 511, it carries the lint and is discharged from the filter device 500.

[0059] In a more specific structure, the bottom of the water tank 100 is connected to a water outlet pipe 410, and the other end of the water outlet pipe 410 is connected to the water inlet chamber 511 of the filter device 500. The water inlet chamber 511 of the filter device 500 is also connected to a drain pipe 430, and the outlet end of the drain pipe 430 extends to the outside of the washing equipment housing 600. The drainage device is a drain valve 431 installed on the drain pipe 430. By controlling the opening and closing of the drain valve 431, the drain pipe 430 can be opened or closed. When the drainage device performs a drainage action, it means that the drain valve 431 is opened to open the drain pipe 430. At this time, the water in the water tank 100 flows through the water inlet chamber 511 and the drain valve 431 of the filter device 500 in sequence, carrying the lint in the water inlet chamber 511 out of the washing equipment.

[0060] In embodiments of the present invention, the filter device 500 can perform a filtration operation and a lint removal operation. The filtration operation refers to the process by which washing water passes through the filter assembly 520 from the inlet chamber 511 of the filter device 500 into the filter chamber 512, thus filtering the washing water. The lint removal operation refers to the process of discharging lint accumulated in the inlet chamber 511.

[0061] By using the drain device of the washing equipment to perform a draining action, the filter device 500 is triggered to perform a lint cleaning action, removing the lint accumulated in the water inlet chamber 511. The draining action refers to the action of discharging the washing water from the water tank 100. The washing equipment will inevitably perform one or more draining actions during a complete washing cycle. Therefore, without active control, the accumulation of lint in the filter device 500 can be avoided, preventing the filter device 500 from being clogged by large amounts of lint and affecting the filtration effect.

[0062] In a further embodiment, the filtration device 500 performs the filtration action by circulating wash water through the filtration device 500.

[0063] Specifically, the filter chamber 512 of the filter device 500 is connected to the return water pipe 420, which leads to the water tank 100. A circulation pump 421 is installed on the return water pipe 420. When the circulation pump 421 is running, water can be drawn from the water tank 100 along the outlet pipe 410 and enter the inlet chamber 511 of the filter device 500. The water then passes through the filter assembly 520 for filtration. The filtered water enters the filter chamber 512 and flows back to the water tank 100 along the return water pipe 420. Threads in the water are intercepted by the filter assembly 520 and collected in the inlet chamber 511.

[0064] When the drain valve 431 is closed, the water tank 100 can hold water. When the water tank 100 needs to drain, the drain valve 431 is opened to open the drain pipe 430, and the water in the water tank 100 can enter the inlet chamber 511 of the filter device 500 along the outlet pipe 410, and then carry the lint in the inlet chamber 511 into the drain pipe 430, and finally be discharged to the outside of the box 600 along the drain pipe 430.

[0065] As a specific structure, the filter device 500 includes a housing 510, and a filter assembly 520 disposed inside the housing 510, dividing the internal space of the housing 510 into an inlet chamber 511 and a filter chamber 512. The housing 510 is provided with an inlet 501, a return inlet 502, and a drain outlet 503. Both the inlet 501 and the drain outlet 503 are connected to the inlet chamber 511, with an outlet pipe 410 connected to the inlet 501 and a drain pipe 430 connected to the drain outlet 503. The return inlet 502 is connected to the filter chamber 512, and a return pipe 420 is connected to the return inlet 502.

[0066] In one specific embodiment, the washing device in this invention is a pulsator-type washing device, comprising a washing tub 200 rotatably disposed within a water tank 100, the washing tub 200 having a dewatering hole 201, and the water tank 100 and the washing tub 200 being connected through the dewatering hole 201. A rotatable pulsator 300 is disposed at the bottom of the washing tub 200. Clothes are placed inside the washing tub 200, and the water tank 100 holds washing water. The clothes are washed by the pulsator 300 rotating independently, or by the washing tub 200 and the pulsator 300 rotating asynchronously and simultaneously.

[0067] The filter device 500 is located at the bottom of the housing 600, and the return water pipe 420 extends upward at least partially. When the circulation pump 421 operates to filter the washing water through the filter device 500, the filtered washing water flows upward along the return water pipe 420 and flows out from the outlet end of the return water pipe 420 and is directly injected into the washing tub 200.

[0068] In a preferred embodiment of the present invention, the outlet end of the return water pipe 420 is located above the washing tub 200, and the filtered washing water is sprayed out from the outlet end of the return water pipe 420 and sprayed into the washing tub 200 through the opening at the top of the washing tub 200.

[0069] In this embodiment of the invention, a filter device 500 is installed outside the water tank 100, along with a corresponding piping structure. A circulation pump 421 drives the washing water to circulate through the filter device 500, achieving a circulating filtration function during the washing process. This removes lint from the water, preventing lint residue from remaining on the clothes after washing. The washing tub 200 does not require a water channel filter on its wall. This increases the internal space of the washing tub 200 without changing the overall size of the machine, thus increasing washing capacity. Furthermore, it avoids the problem of dirt accumulation between the water channels and the inner tub, as is common with existing water channel filters, improving the cleanliness of the inner space of the washing tub 200 and enhancing the user experience.

[0070] The lint in the filter device 500 can be discharged with the water in the water tank 100, without the need for manual cleaning by the user or setting up additional programs to control the discharge of lint. This ensures the filtration effect and simplifies the user operation and the control logic of the washing equipment.

[0071] In embodiments of the present invention, when the washing equipment receives a drainage command, it can control the drainage device to perform a drainage action; when it receives a filtration command, it can control the filtration device 500 to perform a filtration action.

[0072] In one specific implementation, the drainage command includes opening the drain valve 431, and the filtration command includes starting the circulation pump 421.

[0073] Based on the specific structure of the washing equipment described above, when the drainage device performs the drainage action, it automatically triggers the filter device 500 to perform the lint cleaning action. However, if the filtration action and the lint cleaning action of the filter device 500 are performed simultaneously, a conflict will occur. However, the control system 700 of the washing equipment independently controls the drainage device (i.e., the drain valve 431) and the circulating pump 421. If the control system 700 only executes the corresponding action according to the received instructions, it is very likely to cause a conflict in the operation of the filter device 500.

[0074] Example 1

[0075] As shown in Figures 2 to 7, this embodiment provides a control method for a washing device, which can be applied to the above-mentioned washing device to avoid conflicts caused by the operation of the filter device 500 through the program.

[0076] In this embodiment, the control system 700 of the washing equipment controls the drainage and filtration actions to be performed at different times. It should be noted that the location of the control system 700 in Figure 2 is for illustrative purposes only and should not be construed as a limitation of the invention. Where structurally permissible, the control system 700 can also be located at any position within the washing equipment.

[0077] Specifically, as shown in Figure 8, when the washing equipment is running, the control system 700 controls either the drainage action or the filtration action to be executed, or controls neither of the drainage action nor the filtration action to be executed.

[0078] In one specific implementation, the washing equipment performs a drainage action during the drainage phase, discharging the washing water from the water tank 100. During the washing / rinsing phase, the drainage and filtration actions can be selectively performed; specifically, filtration is performed when filtering the washing water is required, and drainage is performed when lint removal is required. Alternatively, when filtering the washing water is not required, neither the drainage nor filtration actions can be performed during the washing / rinsing phase.

[0079] As a specific implementation, the drainage and filtration actions are selectively performed, meaning that only one of the drain valve 431 and the circulation pump 421 is in the open state. The drainage and filtration actions are not performed at all, meaning that both the drain valve 431 and the circulation pump 421 are in the closed state.

[0080] In one specific embodiment of this example, the method for controlling the drainage action and the filtration action to be executed selectively includes: after the control system 700 of the washing equipment receives one of the drainage command and the filtration command, it first needs to determine whether the action corresponding to the received command can be started, and then execute the corresponding action when it is determined that it can be started.

[0081] More specifically, as shown in Figure 9, if the other action is not currently being performed, the action to be started can be started before the washing device starts either the drainage action or the filtration action.

[0082] In detail, the control system 700 of the washing equipment initiates corresponding actions upon receiving a drain command or a filter command. After receiving either the drain command or the filter command, if the action corresponding to the other command is not currently being executed, the control system 700 determines that the received command can be executed.

[0083] In one specific embodiment, after receiving a drainage command, the control system 700 of the washing equipment determines that the circulation pump 421 is in a closed state, indicating that the filtration action is not currently being performed, thus confirming that the drainage command can be executed. At this time, the control system 700 controls the drainage device to perform the drainage action. Specifically, the drain valve 431 is opened, and the washing water in the water tank 100 enters the inlet chamber 511 of the filter device 500, and then flows into the drain pipe 430, triggering the filter device 500 to perform a lint cleaning action, discharging the lint accumulated in the inlet chamber 511.

[0084] Similarly, after receiving the filtration command, if the control system 700 detects that the drain valve 431 is closed, it indicates that the draining action has not been performed, thus determining that the filtration command can be executed. At this time, the control system 700 controls the circulation pump 421 to start, drawing water out of the water tank 100. The washing water flows through the filter device 500 to remove impurities such as lint, and then returns to the washing tub 200 or the water tank 100.

[0085] In another specific embodiment of this example, as shown in FIG10, the method for controlling the selective execution of the drainage action and the filtration action includes: after the washing device initiates one of the drainage action and the filtration action, the other action is prohibited from being selected. Here, "prohibited from being selected" means that the user cannot initiate the other action on the washing device, or the user cannot initiate the other action even after performing the corresponding operation.

[0086] In the specific solution, the control system 700 of the washing equipment receives one of the drainage command and the filtration command, executes the received command, and at the same time, the other command is prohibited from being received, triggered, or selected.

[0087] More specifically, when the control system 700 receives a drainage command, it opens the drainage valve 431, and the water in the water tank 100 flows out through the outlet pipe 410 and the drain pipe 430. During this process, the filtration command is prohibited from being received, triggered, or selected. Similarly, when the control system 700 receives a filtration command, it starts the circulation pump 421, driving the water in the water tank 100 to circulate through the filtration device 500 for filtration. During the filtration process, the drainage command is prohibited from being received, triggered, or selected.

[0088] In one specific embodiment, the washing device has an operation panel, which is provided with at least a filter button corresponding to the filter command and a drain button corresponding to the drain command. The user can issue a filter command or a drain command by operating the filter button and the drain button.

[0089] It should be noted that the "button" mentioned in the embodiments of the present invention can be either a physical button or a virtual button on a touch screen.

[0090] In one specific scheme, when the washing equipment executes one of the drain command and the filter command, the other command is blocked from being received. This means that the user can still operate the button corresponding to the other command, and the button can generate the corresponding command after being triggered by the user. However, the command cannot be received by the control system 700 of the washing equipment, and thus the corresponding component of the washing equipment will not respond.

[0091] In another specific solution, when the washing equipment executes one of the drain command and the filter command, the other command is prohibited from being triggered or selected. This means that the user cannot operate the button corresponding to the other command. For example, virtual buttons on a touch screen may not be displayed. Alternatively, although the user can operate the button corresponding to the other command, the button will not generate the corresponding command after being operated by the user.

[0092] In another specific implementation, the drainage command and the filtration command are automatically triggered according to the running progress of the washing program.

[0093] Specifically, in this embodiment, the filter device 500 performs the filtering action at least during the washing phase of the washing program, and optionally, it can also perform the filtering action during the rinsing phase of the washing program. The washing program has several preset drainage phases, and the drainage device needs to perform the drainage action each time the program reaches the drainage phase.

[0094] In the above scheme, the washing equipment automatically triggers a filtration command when it reaches the washing stage, and optionally, it may also automatically trigger a filtration command during the rinsing stage. A drain command is automatically triggered each time the equipment reaches the draining stage. Accordingly, during the washing stage and the rinsing stage where the filtration command has been triggered, the drain command is disabled from being received, triggered, or selected; and during the draining stage, the filtration command is disabled from being received, triggered, or selected.

[0095] In one specific embodiment, when the washing equipment reaches the drainage stage during the washing program, the drainage command is automatically triggered, controlling the drainage device to perform the drainage action and triggering the filter device 500 to perform the lint cleaning action. Regarding the drainage command automatically triggered during the drainage stage, the filter command is prohibited from being received, triggered, or selected during the drainage action of the drainage device.

[0096] In the detailed scheme, when the washing equipment reaches the drainage stage of the washing program, a drainage command is automatically triggered. The control system 700 opens the drain valve 431 according to the drainage command, allowing the drain pipe 430 to open. The drain water flows through the inlet chamber 511 of the filter device 500, triggering the filter device 500 to perform a lint cleaning action. During the drainage process, the filter command is disabled from being received, triggered, or selected, and the circulation pump 421 remains closed.

[0097] More specifically, in this embodiment, the washing program operated by the washing equipment includes at least a washing process, a rinsing process, and a final dehydration process performed sequentially. The washing process further includes a washing water inlet stage, a washing stage, a washing drainage stage, and a washing dehydration stage. The rinsing process includes at least one, and typically at least two, rinsing cycles, each of which further includes a rinsing water inlet stage, a rinsing stage, a rinsing drainage stage, and a rinsing dehydration stage. The drainage stage described in this embodiment includes a washing drainage stage and each of the rinsing drainage stages.

[0098] In the above scheme, the drainage device continuously performs drainage operations during each drainage stage of the washing program, that is, the drain valve 431 remains open until it detects that the water level in the water tank 100 is empty, at which point the drainage operation ends. During the drainage stage, the filter command for starting the circulation pump 421 is prohibited from being received, triggered, or selected.

[0099] In this way, on the one hand, the washing water entering the inlet chamber 511 of the filter device 500 will only be discharged into the drain pipe 430 through the drain outlet 503, and will not pass through the filter assembly 520 to enter the filter chamber 512, thus ensuring the cleaning effect of the drain water flow on lint. On the other hand, it also avoids the problem of abnormal circulation noise caused by starting the circulation pump 421 when the water level in the water tank 100 is insufficient, which would affect the user experience.

[0100] It is understandable that the primary purpose of the drainage device's drainage action during the drainage phase of the washing program is to completely drain the water from the water tank 100, while triggering the filter device 500 to perform the lint cleaning action is merely an additional effect of the drainage phase. Therefore, disabling the receiving, triggering, or selection of filter control commands during the drainage phase can also avoid affecting the drainage process and ensure drainage efficiency.

[0101] The washing equipment described in this embodiment is a pulsator-type washing equipment, which has a water tank 100 and a washing tub 200 arranged coaxially. The bottom of the washing tub 200 has a rotatable impeller 300. The water tank 100 and the washing tub 200 are connected through a dewatering hole 201 provided on the washing tub 200. A filter device 500 is located below the bottom of the water tank 100. The return water pipe 420 is led out from the return water port 502 of the filter device 500, extends upward outside the water tank 100, and finally passes through the water tank 100 to reach the top of the opening of the washing tub 200, spraying the filtered washing water into the washing tub 200.

[0102] The filter device 500, by eliminating the need for a water channel filter, provides washing water filtration. Located outside the water tank 100, it doesn't occupy internal space, increasing washing capacity without increasing the overall machine size. Simultaneously, it eliminates the area between the water channel of the water channel filter and the washing tub 200 where dirt and grime can easily accumulate, improving the cleanliness of the washing space within the tub. During the washing process, the washing water continuously circulates and filters, thereby improving lint removal and enhancing the cleaning effect on clothes.

[0103] The lint cleaning in the filter device 500 is automatically triggered by the drainage action, eliminating the need for manual cleaning by the user or additional programming to control the lint discharge. The existing control logic of the washing equipment can complete the lint cleaning process. Specifically, after each washing cycle, the washing equipment uses drainage water to remove the lint accumulated during the cycle, preventing lint buildup from clogging the filter device 500 and affecting its filtration efficiency. It also prevents damp lint from remaining inside the filter device 500 for extended periods, which could breed bacteria and cause secondary contamination of clothes during washing.

[0104] By controlling the process through the program to prevent the drainage and filtration actions from being executed simultaneously, specifically by determining whether the other action is being executed before starting either the drainage or filtration action, or by preventing the other action from being selected after starting either the drainage or filtration action, the conflict caused by the filter device 500 simultaneously executing the filtration and lint cleaning actions can be avoided, thus ensuring the filtration and lint cleaning effects.

[0105] Example 2

[0106] As shown in Figure 11, this embodiment provides a control method for a washing device. The difference from the first embodiment is that if the washing device is performing another action before starting either the drainage action or the filtration action, the execution of the other action is interrupted, and the action to be started is executed first.

[0107] In the specific solution, after the control system 700 of the washing equipment receives one of the drainage command and the filtration command, it determines that the action controlled by the other command is being executed, and then interrupts the action being executed and executes the action controlled by the received command first.

[0108] More specifically, in this embodiment, after receiving one of the drainage command and the filtration command, the control system 700 of the washing equipment determines whether the action controlled by the other command is being executed. If the determination result is no, it is determined that the received command can be executed, and then the received command is executed. If the determination result is yes, the currently executing action is interrupted, and the received command is executed first.

[0109] Referring to Figures 2 to 7, in one specific embodiment, after receiving a drainage command, the control system 700 of the washing equipment, if it detects that the circulation pump 421 is currently running, shuts down the circulation pump 421, interrupting the filtration operation, and then opens the drain valve 431 to drain water. The drain water flow triggers the filter device 500 to perform a lint cleaning operation, discharging the lint from the water inlet chamber 511 with the water flow. If the circulation pump 421 is currently off, the drain valve 431 can be opened directly.

[0110] After receiving a filtration command, the control system 700 of the washing equipment closes the drain valve 431 if it finds that the drain valve 431 is currently open, and then starts the circulation pump 421 to drive the washing water to circulate through the filter device 500, thus achieving the circulation filtration of the washing water. If the drain valve 431 is currently closed, the circulation pump 421 can be started directly.

[0111] In a further embodiment of this invention, after the action to be started is initiated and executed, the washing device then executes the interrupted action.

[0112] In one specific implementation, once the action initiated according to the received instruction is completed, the washing equipment can automatically resume the interrupted action without needing to receive another instruction. In other words, the user does not need to operate the washing equipment again to trigger another instruction, and the washing equipment will not automatically trigger another instruction to be sent to the control system 700 after the received instruction is completed.

[0113] As another specific implementation, after the action initiated according to the received instruction is completed, the control system 700 of the washing equipment waits to receive another instruction, and then executes it after receiving the other instruction.

[0114] Specifically, after the received instruction is executed, the control system 700 of the washing equipment waits for the user to trigger another instruction before controlling the execution of that other instruction.

[0115] For example, in one specific solution, after the washing equipment executes the received instruction, it waits for the user to trigger another instruction, and then executes that other instruction after receiving it. More specifically, the user can trigger the other instruction by pressing the corresponding button on the control panel.

[0116] As a specific embodiment, after receiving a drainage command, the control system 700 of the washing equipment, if determining that a filtration operation is in progress, interrupts the filtration operation and first controls the drainage device to perform the drainage operation. After the drainage operation is completed, the filtration device 500 continues to perform the filtration operation.

[0117] More specifically, the control system 700 receives the drainage command, determines that the circulation pump 421 is currently running, and then shuts down the circulation pump 421 to interrupt the filtration operation. Then, it controls the drainage valve 431 to open and drain the water, using the drainage flow to trigger the filter device 500 to perform a lint cleaning action, discharging the lint from the inlet chamber 511 with the water flow. After this drainage operation is completed, the circulation pump 421 is restarted, allowing the filter device 500 to continue performing the filtration operation.

[0118] It is understood that in this embodiment, the filter device 500 usually performs the filtration action during the washing or rinsing stage. That is, the situation where the filtration action is being performed after receiving the drainage command and then needs to be interrupted generally occurs during the washing or rinsing stage, rather than the drainage stage.

[0119] In this embodiment, a drain command is triggered during the washing or rinsing phase to clean lint from the filter device 500. After the draining action is completed, the current washing or rinsing phase needs to continue. To save water, the drainage volume needs to be controlled to prevent the washing water in the water tank 100 from being completely drained.

[0120] Therefore, in a further embodiment, after the filtration action is interrupted, the drainage device continues to perform the drainage action for a set time, and then the drainage action ends.

[0121] As a specific solution, after receiving a drainage command, the control system 700 of the washing equipment detects that the circulation pump 421 is in operation. It first shuts down the circulation pump 421, then opens the drain valve 431 to drain water. After the drain valve 431 remains open for a set time, it closes, ending the drainage process.

[0122] In the above scheme, the set duration can be determined through pre-testing and must meet the following requirements: when the washing equipment continuously drains water for the set duration, most of the lint in the water inlet chamber 511 of the filter device 500 can be washed away without affecting the subsequent filtration effect.

[0123] In another further embodiment, after the execution of the filtering command is interrupted, the drainage device continues to perform the drainage action. When it is determined that the drainage volume of this drainage action has reached the set water volume, the drainage action ends.

[0124] As a specific solution, after receiving a drainage command, the control system 700 of the washing equipment detects that the circulation pump 421 is in operation. It first shuts down the circulation pump 421, then opens the drain valve 431 to drain water. The drain valve 431 remains open, and the washing equipment obtains the drainage volume for this drainage action. When the set water volume is reached, the drain valve 431 is closed, and the drainage action ends.

[0125] In the above scheme, the set water volume can be determined through pre-testing and needs to meet the following requirements: when the continuous drainage volume of the washing equipment reaches the set water volume, most of the lint in the water inlet chamber 511 of the filter device 500 can be washed away without affecting the subsequent filtration effect.

[0126] To obtain the aforementioned drainage volume, in one specific solution, a flow sensor is installed on the outlet pipe 410 or the drain pipe 430, and the drainage volume is directly detected by the flow sensor. In another specific solution, the water tank 100 is equipped with a water level sensor. During the drainage process, the real-time water level in the water tank 100 is detected by the water level sensor, compared with the initial water level before drainage begins, and the decrease in water level is determined, which is then converted into the drainage volume.

[0127] In a preferred embodiment, after the drainage device begins to perform the drainage action, the washing equipment replenishes water into the water tank 100. Specifically, water replenishment into the water tank 100 can begin during the drainage process or can be done after the drainage process is completed.

[0128] Furthermore, the filter device 500 continues to perform the filtration operation after the drainage operation is completed and the water is replenished.

[0129] As a specific implementation, after receiving a drainage command, the control system 700 of the washing equipment detects that the circulation pump 421 is in operation. It first shuts down the circulation pump 421, then opens the drain valve 431 to begin draining water. Once the set time is reached, or the drainage volume reaches the set amount of water, the drain valve 431 is closed.

[0130] After the drain valve 431 is opened, or after the drain valve 431 is closed, the water inlet system of the washing equipment replenishes water into the water tank 100. When the drain valve 431 is closed and the current water level in the water tank 100 is the same as the initial water level before drainage begins, water replenishment to the water tank 100 stops. At this time, the circulation pump 421 is restarted, and the filter device 500 continues to perform filtration.

[0131] In the above scheme, the washing equipment replenishes water into the water tank 100 after draining to ensure sufficient washing water volume. On the one hand, this ensures the cleaning effect of clothes during the continued washing or rinsing stage, avoiding insufficient water to effectively clean clothes. On the other hand, since the filter device 500 continues to perform filtration and replenish the washing water volume into the water tank 100, it also prevents the circulation pump 421 from operating when the water volume is insufficient.

[0132] In this embodiment, if the washing device is performing another action while receiving a corresponding instruction to initiate either the drainage or filtration action, the execution of the other action is interrupted, and the action to be initiated is executed first, resulting in a more timely response to the received instructions. Especially when a drainage instruction is received during the filtration action, drainage can be prioritized to clean the lint from the filter device 500, ensuring the subsequent filtration effect.

[0133] Example 3

[0134] As shown in Figure 12, this embodiment provides a control method for a washing device. The difference from the above embodiments one and two is that if the washing device is performing another action before starting either the drainage action or the filtration action, the action to be started will not be executed.

[0135] In the specific solution, after the control system 700 of the washing equipment receives one of the drainage command and the filtration command, it determines that the action controlled by the other command is being executed, and therefore the received command is invalid.

[0136] In this embodiment, "the received instruction is invalid" means that the washing device does not execute the received instruction, which is equivalent to ignoring the received instruction.

[0137] Furthermore, if it is determined that the action controlled by another instruction is not currently being executed, then the received instruction can be executed.

[0138] In one specific implementation, when the washing machine's control panel is equipped with a filter button and a drain button, both buttons can be operated by the user regardless of whether the washing machine is currently executing a filter or drain command, generating a corresponding filter / drain command and sending it to the washing machine's control system 700. Upon receiving the command, the control system 700 determines whether the action controlled by the other command is currently being executed, and then decides whether to execute or ignore the received command.

[0139] Specifically, referring to Figures 2 to 7, after receiving a drain command, the control system 700 of the washing equipment determines whether the filter device 500 is currently performing a filtration operation. If so, the received drain command is invalid, and the drain device does not operate. If the filter device 500 is not currently filtering the washing water, then the drain device can be controlled to perform a drain operation.

[0140] Similarly, after receiving a filtration command, the control system 700 of the washing equipment determines whether the drainage device is currently draining water. If so, the received filtration command is invalid, and the washing equipment will not control the filtration device 500 to perform the filtration operation. However, if there is no drainage at present, then the washing water can be filtered.

[0141] More specifically, after receiving a drain command, the control system 700 of the washing equipment obtains the operating status of the circulation pump 421. If the circulation pump 421 is running, the received drain command is invalid, and the drain valve 431 remains closed and does not operate. If the circulation pump 421 is closed, the drain valve 431 can be opened to drain water.

[0142] After receiving a filtration command, the control system 700 of the washing equipment obtains the status of the drain valve 431. If the drain valve 431 is open, the received filtration command is invalid, and the circulation pump 421 remains closed and does not start. However, if the drain valve 431 is closed, the circulation pump 421 can be started to circulate and filter the washing water.

[0143] In a further embodiment of this invention, as shown in FIG12, the washing device waits for another action being performed to stop before performing the aforementioned action to be started.

[0144] In one specific embodiment, after receiving a drain command, the control system 700 of the washing equipment determines that a filtration operation is in progress, and therefore invalidates the received drain command. The washing equipment waits for the filtration operation to stop before performing the drain operation.

[0145] More specifically, the washing equipment waits for the filtration action to stop and automatically triggers a drain command when the washing program reaches the draining stage. After receiving the automatically triggered drain command, the control system 700 controls the draining device to perform the draining action, at which point it is not necessary to determine again whether the filtration action is in progress.

[0146] Specifically, after receiving a drain command during the washing or rinsing stage, if the washing equipment detects that the circulation pump 421 is currently running, it indicates that the filter device 500 is performing a filtration operation, and the received drain command is invalid. The washing equipment continues to run the current washing or rinsing stage, shuts off the circulation pump 421 before the end of the washing / rinsing stage, and then automatically triggers a drain command when running to the next draining stage. The control system 700 controls the drain valve 431 to open according to the automatically triggered drain command, and begins draining.

[0147] Furthermore, similar to Embodiment 2, this embodiment triggers a drain command during the washing or rinsing phase to clean lint from the filter device 500. This drain command can be triggered manually by the user or by the washing equipment monitoring the accumulation of lint in the filter device 500.

[0148] In one specific embodiment, when the control system 700 of the washing equipment receives a drainage command and determines that the filtration action is being performed, it controls the filtration device 500 to immediately stop performing the filtration action. When the washing program reaches the drainage stage and automatically triggers the drainage command, the drainage device performs the drainage action, discharging the washing water in the water tank 100 while simultaneously flushing away the lint accumulated in the filtration device 500 with the drainage water flow.

[0149] In the above scheme, when a drain command is received while the filtration process is in progress, the washing equipment will not drain the water immediately. Instead, it will wait until the next draining stage to clean the lint accumulated in the filter device 500. At this time, the washing equipment controls the filter device 500 to stop performing the filtration process. Specifically, after receiving the drain command, the circulation pump 421 is turned off, and washing water carrying lint is no longer introduced into the filter device 500. This prevents the filter device 500 from continuing to filter and becoming completely clogged by lint.

[0150] In another specific embodiment, when the control system 700 of the washing equipment receives a drainage command and determines that a filtration operation is in progress, it can control the filter device 500 to continue performing the filtration operation, stopping the filtration operation just before the current washing / rinsing stage is about to end. Then, the washing program runs to the drainage stage, at which point a drainage command is automatically triggered, and the drainage device performs the drainage operation, draining the washing water in the water tank 100 while simultaneously removing the lint accumulated in the filter device 500 with the drainage water flow.

[0151] The above solution mainly addresses the implementation method of a washing machine triggering a drainage command by monitoring the accumulation of lint in the filter device 500. By reasonably setting the preset conditions for triggering the drainage command, when the drainage command is triggered, a certain amount of lint has accumulated in the filter device 500, but it still has the ability to continue filtering wash water, rather than being completely blocked by lint. In this case, the filter device 500 can be controlled to continue filtering wash water in the current program stage to ensure the lint removal effect, and then stop filtering just before the drainage stage begins. Then, when the washing program reaches the drainage stage, the drainage command is automatically triggered, and the drainage device performs the drainage action, draining the wash water in the water tank 100 while simultaneously flushing away the lint accumulated in the filter device 500 with the drainage water flow.

[0152] In this embodiment, if the washing equipment determines that the other action is being performed before initiating either the drainage or filtration action, it will not execute the action to be started. This effectively avoids the conflict between the filtration device 500 filtering the washing water and the lint discharge action. Using the solution provided in this embodiment, the actions being performed by the washing equipment will not be interrupted, ensuring optimal operating results.

[0153] Example 4

[0154] As shown in Figures 2 to 7, this embodiment provides a further control method for the washing equipment based on the above embodiments one to three. In this embodiment, different control logics are used in different stages of the washing process to prevent the drainage and filtration actions from being performed simultaneously.

[0155] As a specific implementation method, in this embodiment, during the washing stage of the washing program, the washing equipment adopts the control method provided in Embodiment 3: if the washing equipment is currently performing a filtration action before starting the drainage action during the washing stage, then the drainage action cannot be started.

[0156] Specifically, if the control system 700 of the washing equipment receives a drain command during the washing phase and determines that a filtration command is currently being executed, then the received drain command is invalid.

[0157] More specifically, if the control system 700 receives a drain command during the washing phase and finds that the circulating pump 421 is in operation, it means that the filter device 500 is filtering the circulating washing water, and the received drain command is invalid.

[0158] Furthermore, when the current washing stage ends and the washing and draining stage begins, the washing equipment will automatically trigger a drain command. The control system 700 of the washing equipment receives this automatically triggered drain command, controls the draining device to perform the draining action, and triggers the filter device 500 to perform the lint cleaning action.

[0159] Specifically, before the washing stage ends, the circulation pump 421 is turned off, stopping the execution of the filtration command. When the washing program reaches the washing and draining stage, a drain command is automatically triggered. The control system 700 receives the drain command and controls the drain valve 431 to open. The washing water in the water tank 100 flows sequentially through the water outlet pipe 410, the water inlet chamber 511 of the filter device 500, and the drain pipe 430 and drain valve 431, carrying the lint in the water inlet chamber 511 out with it.

[0160] In the above scheme, since the washing water contains detergent during the washing stage, the operation of draining water is not carried out in the middle of the washing stage to avoid the loss of detergent and affect the cleaning effect of the clothes.

[0161] As a specific implementation method, in this embodiment, during the rinsing stage of the washing program, the washing equipment adopts the control method provided in Embodiment 2: before the washing equipment starts the drainage action during the rinsing stage, if the filtration action is currently being performed, the filtration action is interrupted and the drainage action is performed first.

[0162] Specifically, if the control system 700 of the washing equipment receives a drain command during the rinsing stage and determines that a filtration action is currently being performed, the filtration action is interrupted, and the drain command is executed first.

[0163] More specifically, after receiving a drainage command during the rinsing stage, if the control system 700 detects that the circulation pump 421 is in operation, it shuts down the circulation pump 421 and then opens the drain valve 431 to drain water, using the drainage water flow to carry the lint in the inlet chamber 511 of the filter device 500 out.

[0164] Furthermore, if the duration of the open drain valve 431 reaches a set duration, or if the drainage volume during the open period of the drain valve 431 reaches a set volume, the drain valve 431 is closed.

[0165] Preferably, after the drainage device begins its drainage operation, the washing equipment replenishes water into the water tank 100. Specifically, water replenishment to the water tank 100 can begin during the drainage process or can be done after the drainage operation is completed. The filtration device 500 continues its filtration operation after both the drainage and water replenishment processes are finished.

[0166] Specifically, after the drain valve 431 is opened during the rinsing stage, or after the drain valve 431 is closed, the water inlet system of the washing equipment replenishes water into the water tank 100. When the drain valve 431 is closed and the current water level in the water tank 100 is the same as the initial water level before drainage begins, water replenishment to the water tank 100 stops. At this time, the circulation pump 421 is restarted, and the filter device 500 continues to perform the filtration operation.

[0167] In the above solution, if a drain command is received during the filtration process in the rinsing stage, drainage can be prioritized to clean the lint in the filter device 500. After replenishing water in the water tank 100, filtration continues, ensuring the subsequent filtration effect. Since the rinsing stage primarily removes detergent from the clothes, draining and replenishing water during the rinsing process does not affect the rinsing effect.

[0168] As a specific implementation method, in this embodiment, the washing equipment adopts the control method provided in Embodiment 1 in each drainage stage of the washing program: during the drainage stage, the washing equipment performs the drainage action, and the filtration action is prohibited from being selected at this time.

[0169] Specifically, during the drainage phase, the washing equipment controls the drainage device to perform the drainage action, at which time the filtration command is prohibited from being received, triggered, or selected.

[0170] More specifically, when the washing machine reaches the draining stage of the washing program, a drain command is automatically triggered. The washing machine's control system 700 receives this drain command and controls the draining device to perform the draining action, that is, controls the drain valve 431 to open and drain the water. At the same time, the filtration command is disabled from being received, triggered, or selected.

[0171] In the above solution, when the washing equipment performs the drainage action during the drainage phase, the filtration command is prevented from being received, triggered, or selected, thus ensuring that the drainage process is not interrupted by the triggering of the filtration command and guaranteeing drainage efficiency. At the same time, the above solution ensures that the circulation pump 421 will not start during the drainage phase, and also avoids the problem of abnormal circulation noise caused by starting the circulation pump 421 when a large amount of washing water is discharged from the water tank 100.

[0172] In this embodiment, the washing equipment employs different control logics at different stages of the washing program. On the one hand, this ensures that the drainage and filtration actions are not executed simultaneously, thus preventing conflicts in the operation of the filter device 500. On the other hand, it can adapt to the specific circumstances of different stages of the washing program. For example, during the washing stage, no drainage is used to avoid wasting detergent; during the rinsing stage, drainage is prioritized for lint removal to ensure subsequent filtration effectiveness; and during the drainage stage, the drainage process is not interrupted to ensure drainage efficiency.

[0173] Example 5

[0174] As shown in Figures 2 to 7, this embodiment further defines the above embodiments and provides a specific structure for a filter device 500 applied to the washing equipment described in the above embodiments.

[0175] Specifically, in this embodiment, the filter assembly 520 is disposed inside the housing 510 of the filter device 500, dividing the internal space of the housing 510 into a water inlet chamber 511 and a water filter chamber 512, and the water inlet chamber 511 and the water filter chamber 512 are respectively located on both sides of the filter assembly 520.

[0176] The side surface of the filter assembly 520 facing the water inlet chamber 511 is the filter surface 522. When the washing water to be filtered passes through the filter assembly 520, some of the lint in the water adheres to the filter surface 522.

[0177] The filter device 500 has the above-described structure. The filtered washing water flows along the opposite side of the filter surface 522 and is discharged from the water filter chamber 512. Meanwhile, the drainage water used to clean the lint flows along the same side of the filter surface 522, carrying the lint attached to the filter surface 522 and the lint remaining in other locations in the water inlet chamber 511 out of the water inlet chamber 511.

[0178] In a further embodiment, the filter assembly 520 is made of a material capable of elastic deformation. When the filter device 500 performs the filtering action of filtering washing water, the filter assembly 520 bends toward the side where the water filter chamber 512 is located due to the impact force of the water flow passing through it. When the filter device 500 performs the lint cleaning action, the filter assembly 520 bends toward the side where the water inlet chamber 511 is located.

[0179] In one specific embodiment, the filter assembly 520 is a filter screen 521 capable of elastic deformation, which is arranged horizontally or nearly horizontally in the housing 510 of the filter device 500. A water inlet chamber 511 is formed on the lower side of the filter screen 521, and a water filtration chamber 512 is formed on the upper side.

[0180] When the circulating pump 421 is running, causing the filter device 500 to perform the filtration action, the water flows from bottom to top through the filter screen 521. Under the impact of the water flow, the filter screen 521 undergoes an upward bending deformation, as shown in Figure 5.

[0181] When the circulation pump 421 is turned off and the filter device 500 stops performing the filtration operation, as shown in Figure 6, the water remaining in the return pipe 420 flows back under gravity and enters the filter chamber 512, passing through the filter screen 521 from top to bottom, which can wash away some of the lint attached to the lower side of the filter screen 521 (i.e., the filter surface 522). At the same time, the filter screen 521 bends downward under its own elasticity and the impact of the return water flow.

[0182] After the residual water in the return pipe 420 is drained, as shown in Figure 7, the water flow impact force acting directly on the filter screen 521 in the vertical direction disappears. The filter screen 521, under its own elasticity, tends to return to its original state, which can bounce the remaining lint off the filter surface 522. The drain valve 431 opens after the circulation pump 421 is shut off, performing the drainage action. The washing water in the water tank 100 passes through the water inlet chamber 511 on the lower side of the filter screen 521, carrying the detached lint out of the water inlet chamber 511. Simultaneously, during the drainage process, the filter screen 521, due to its own elasticity, will also bend downwards and generate a certain amplitude of vibration, which helps to thoroughly detach the lint attached to the filter surface 522, allowing the detached lint to be discharged with the drainage water. In addition, the drainage water flows along the filter surface 522 within the water inlet chamber 511, further ensuring the thorough cleaning of the lint.

[0183] In this embodiment, an elastic filter screen 521 is used as the filter component 520. The filter screen 521 can undergo elastic deformation under the impact of water flow, and then can generate a certain amplitude of vibration under its own elasticity after the impact disappears, which will bounce off the lint attached to the filter surface 522, improve the lint removal efficiency, and make it easier to clean the lint with the drainage water flow.

[0184] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
