Description

Control method of washing apparatus and washing apparatus TECHNICAL FIELD

[0001] The present application belongs to the technical field of washing apparatus, in particular, relates to a control method of washing apparatus and washing apparatus. BACKGROUND

[0002] Traditional washing apparatus often soaks clothes through washing water, and drives clothes to overturn in washing water to realize clothes cleaning. With the development of society, people's living standards are improving, and the demand for clothes washing and protection is gradually increasing. The above-mentioned single clothes cleaning method gradually cannot meet the increasing clothes washing and protection demand of users. Therefore, the washing apparatus capable of realizing more diversified clothes cleaning methods is proposed in the prior art to improve the clothes cleaning effect.

[0003] For example, an existing washing apparatus has a washing water circulation function, which can drive the washing water in the water containing cylinder to flow circularly through the pipeline outside the cylinder during clothes cleaning, so as to enhance the flow of washing water, promote the dissolution of washing agent, and improve the cleaning effect. If used with a filtering device, the washing water can be circularly filtered during washing to remove the lint shed during clothes washing, so as to avoid the attachment of lint or fluff on the surface of clothes after washing, and improve the user experience.

[0004] In order to drive the circulation of washing water, most washing apparatuses are provided with a circulation pump to provide circulation power. However, due to the structure and working mode of the circulation pump, if the water amount in the water containing cylinder is small, for example, when the water containing cylinder is draining water outward, water and gas are likely to coexist in the circulation pump. At this time, the continuous operation of the circulation pump will cause circulation abnormal sound, which is not good for user experience.

[0005] Therefore, the present application is proposed. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art, and to provide a control method of washing apparatus and washing apparatus. The operation of circulating washing water and draining water is prohibited from being executed simultaneously through program control, which avoids the problem of circulation abnormal sound caused by circulating washing water when the water amount in the water containing cylinder is reduced.

[0007] To solve the above technical problems, the basic idea of the technical solution of the present application is:

[0008] A control method of washing apparatus, the washing apparatus has a water containing cylinder, and a circulation pipeline communicated with the water containing cylinder at two ends, the washing apparatus has a first instruction for driving the washing water in the water containing cylinder to flow circularly along the circulation pipeline, and a second instruction for driving the washing water in the water containing cylinder to drain outward,

[0009] Any one of the first instruction and the second instruction is being executed, the other instruction is prohibited from being executed simultaneously.

[0010] Further, after the washing apparatus receives one of the first instruction and the second instruction, the received instruction is executed, and the other instruction is prohibited from being received or triggered or selected.

[0011] Further, after the washing apparatus receives one of the first instruction and the second instruction, it is determined that the other instruction is being executed, and the received instruction is invalid.

[0012] Further, after the washing apparatus receives one of the first instruction and the second instruction, it is determined that the other instruction is being executed, and the received instruction is executed after the execution of the other instruction is completed.

[0013] Further, after the washing apparatus receives one of the first instruction and the second instruction, it is determined that the other instruction is being executed, and the execution of the other instruction is interrupted, and the received instruction is executed first; after the execution of the received instruction is completed, the other instruction is executed.

[0014] Further, after the washing apparatus receives one of the first instruction and the second instruction, and it is determined that the other instruction is being executed, the execution of the other instruction is suspended, and the received instruction is executed first; after the execution of the received instruction is completed, the washing apparatus continues to execute the other instruction from the suspended node.

[0015] Alternatively, after the washing apparatus receives one of the first instruction and the second instruction, and it is determined that the other instruction is being executed, the execution of the other instruction is stopped, and the received instruction is executed first; after the execution of the received instruction is completed, the washing apparatus re-executes the other instruction.

[0016] Further, after the execution of the received instruction is completed, the washing apparatus waits for the other instruction to be triggered before executing the other instruction.

[0017] Alternatively, after the execution of the received instruction is completed, the washing apparatus automatically resumes the execution of the other instruction.

[0018] Further, the first instruction and the second instruction have different priorities.

[0019] After the washing apparatus receives one of the first instruction and the second instruction, and it is determined that the other instruction is being executed, it is further determined whether the received instruction has a higher priority; if yes, the execution of the other instruction is interrupted, and the received instruction is executed first; otherwise, the other instruction is executed first, and then the received instruction is executed.

[0020] Preferably, the second instruction has a higher priority than the first instruction, or the washing apparatus determines the priority of the first instruction and the second instruction according to a user's setting.

[0021] Further, the washing apparatus has an openable / closable additional cycle function, and the opening of the additional cycle function triggers the first instruction.

[0022] Preferably, the washing apparatus has a plurality of preset washing programs, at least one of which has the additional cycle function opened by default, and at least one of which has the additional cycle function closed by default.

[0023] A washing apparatus performing the control method of the washing apparatus described above;

[0024] Preferably, a filtering device is arranged on the circulation pipeline, and the washing water flows along the circulation pipeline and is filtered by the filtering device; and the washing water is discharged without passing through the filtering device.

[0025] Compared with the prior art, the present application has the following beneficial effects.

[0026] In the present application, the washing apparatus controls the circulation of washing water and the drainage operation to be prohibited from being performed simultaneously, thereby avoiding the conflict between the two operations, and especially avoiding the problem of easy generation of circulation noise when the water level in the tub is reduced, and improving the user experience.

[0027] In the present application, in one specific scheme, the washing apparatus cannot be operated by the user to issue another instruction after starting to execute any one of the first instruction and the second instruction, or the operation of the user to trigger another instruction is invalid, and the control logic is simple. In another specific scheme, the washing apparatus can wait for the execution of the instruction being executed to be completed, and then execute the received instruction without the need for the user to operate again. In still another specific scheme, the washing apparatus can interrupt the execution of the instruction, execute the received instruction preferentially, and then execute another instruction after the execution of the received instruction is completed, which is suitable for the case where the work of the circulation of washing water and the drainage has different priority degrees.

[0028] In the present application, the circulation of washing water is set as a separate additional function, which can be opened or closed by the user, and can more flexibly adapt to the actual needs of the user; for the case where the additional cycle function is opened during the running of the washing program, the first instruction is triggered automatically, so that the execution according to the program setting is ensured, and the work of the circulation of washing water and the drainage is prevented from being in conflict.

[0029] In the present application, the washing apparatus is provided with a filtering device on the circulation pipeline, and the washing water can be filtered by circulation, so that the lint in the water is removed, thereby avoiding the attachment of lint on the surface of the clothes after the clothes are washed.

[0030] The specific embodiments of the present application will be further described with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0045] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0046] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0047] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0048] The embodiments of the present application provide a control method of a washing device, and a washing device for executing the control method. The washing device can be a washing machine, a washer-dryer, a care machine, or the like, which is a household appliance having a laundry cleaning function.

[0049] Specifically, as shown in FIG. 1 to FIG. 3, the washing apparatus has a water containing tub 100, and a circulation pipeline having two ends respectively communicated with the water containing tub 100, and a circulation driving component arranged on the circulation pipeline for driving the washing water to flow along the circulation pipeline. The washing apparatus also has a drainage pipeline having one end communicated with the water containing tub 100 and the other end extended to outside of the washing apparatus, and a drainage driving component arranged on the drainage pipeline for driving the washing water in the water containing tub 100 to drain out along the drainage pipeline.

[0050] More specifically, a rotatable washing drum 120 is arranged inside the water containing tub 100. During operation of the washing apparatus, the washing water is contained in the water containing tub 100, and the laundry is placed in the washing drum 120. A washing motor 121 arranged at the rear side of the water containing tub 100 drives the washing drum 120 to rotate, thereby driving the laundry and the washing water to overturn in the washing drum 120, so as to realize the cleaning of the laundry.

[0051] During operation of the washing apparatus, the circulation operation and the drainage operation can be performed. Specifically, the circulation operation includes that the circulation driving component is started to operate, the washing water in the water containing tub 100 is drawn into the circulation pipeline, the washing water flows along the circulation pipeline and returns to the water containing tub 100, so as to form a circulation flow. The drainage operation includes that the drainage driving component is started to operate, the washing water in the water containing tub 100 is drawn into the drainage pipeline, and the washing water is drained out of the washing apparatus along the drainage pipeline.

[0052] As a specific embodiment, the circulation driving component is a circulation pump 320, and the drainage driving component is a drainage pump 310. The washing apparatus controls the start and stop of the circulation pump 320 and the drainage pump 310, so as to control the execution of the circulation operation and the drainage operation.

[0053] In further structure, the circulation pipeline includes a pump hose 210, a circulation pipe 220 and a backwater pipe 250 communicated in sequence. One end of the pump hose 210 is connected to the bottom of the water containing tub 100, and the other end is communicated with the water inlet end of the circulation pump 320. The water outlet end of the circulation pipe 220 is connected to the circulation pipe 220, and the circulation pipe 220 extends upward at least partially and is communicated with one end of the backwater pipe 250 above the water containing tub 100. The other end of the backwater pipe 250 is connected to the window gasket 110 at the opening of the water containing tub 100, and the washing water passes through the window gasket 110 and returns to the water containing tub 100.

[0054] Further, the drainage pipeline shares part of the pipeline structure with the circulation pipeline. Specifically, the drainage pipeline includes the pump hose 210 and a drainage pipe 230. The other end of the pump hose 210 is connected to the water inlet end of the drainage pump 310, and one end of the drainage pipe 230 is connected to the water outlet end of the drainage pump 310, and the other end is extended to outside of the cabinet of the washing apparatus.

[0055] As a specific embodiment, the drainage pump 310 is internally kept in a state of being always turned on, and has an additional opening for communicating with the circulation pump 320. Specifically, the additional opening of the drainage pump 310 can be directly connected with the circulation pump 320 or can communicate with the circulation pump 320 through a pipeline.

[0056] When the drainage pump 310 is running, the washing water in the water tub 100 is drawn along the pump hose 210 and is driven to flow into the drain pipe 230 and then is discharged out of the washing equipment along the drain pipe 230. When the circulation pump 320 is running, the washing water in the water tub 100 is drawn along the pump hose 210 and then flows to the circulation pump 320 through the drainage pump 310, is driven by the circulation pump 320 to flow into the circulation pipe 220, and finally flows back to the water tub 100 along the backwater pipe 250.

[0057] However, when the amount of washing water in the water tub 100 is small, the drainage pump 310 and the circulation pump 320 are prone to coexist with water vapor. Especially for the circulation pump 320, if it is running under the condition that the amount of water in the water tub 100 is reduced, it will cause a circulation abnormal sound, affecting the user's experience.

[0058] Embodiment One

[0059] The embodiment provides a control method of a washing equipment, which can be applied to the above washing equipment and avoids the generation of a circulation abnormal sound by program control.

[0060] As shown in FIGS. 1 to 3, in the embodiment, the washing equipment has a first instruction for driving the washing water in the water tub 100 to flow along the circulation pipeline and a second instruction for driving the washing water in the water tub 100 to be discharged outwards. That is, the first instruction is used to perform a circulation operation, and the second instruction is used to perform a drainage operation.

[0061] The washing equipment in the embodiment prohibits the execution of one instruction when the other instruction is being executed.

[0062] As a specific scheme of the embodiment, as shown in FIG. 4, after the washing equipment receives one of the first instruction and the second instruction, the received instruction is executed, and the other instruction is prohibited from being received or triggered or selected.

[0063] Specifically, when the washing equipment receives the first instruction, the washing water starts to be circulated, and the second instruction is prohibited from being received or triggered or selected during the circulation of the washing water. Similarly, when the washing equipment receives the second instruction, the washing water starts to be discharged outwards, and the first instruction is prohibited from being received or triggered or selected during the drainage process.

[0064] As a specific embodiment, the washing apparatus has an operation panel, on which a cycle key and a draining key corresponding to the first instruction and the second instruction respectively are arranged, and the user can issue the first instruction or the second instruction by operating the cycle key and the draining key.

[0065] It should be noted that the "key" in the embodiments of the present application can be a physical button or a virtual key on a touch screen.

[0066] In a specific solution, when the washing apparatus executes any instruction, the other instruction is prohibited from being received, which means that the user can still operate the key corresponding to the other instruction, and the key can generate the corresponding instruction when triggered by the user, but the instruction cannot be received by the main control module of the washing apparatus, and thus no response can be made.

[0067] In another specific solution, when the washing apparatus executes any instruction, the other instruction is prohibited from being triggered or selected, which means that the user cannot operate the key corresponding to the other instruction, for example, the virtual key on the touch screen can not be displayed; or the user can operate the key corresponding to the other instruction, but the key will not generate the corresponding instruction when operated by the user.

[0068] As another specific embodiment, the first instruction and the second instruction are automatically triggered according to the running process of the washing program.

[0069] Specifically, in the present embodiment, the washing apparatus performs the cycle operation at least in the washing stage of the washing program, and optionally, the cycle operation can also be performed in the rinsing stage of the washing program. The washing program has a plurality of preset draining stages, and the draining operation needs to be performed each time the draining stage is reached.

[0070] In the above solution, the washing apparatus automatically triggers the first instruction when running to the washing stage, and optionally, the first instruction can also be automatically triggered in the rinsing stage. The second instruction is automatically triggered each time the draining stage is reached. Accordingly, in the washing stage and the rinsing stage in which the first instruction is triggered, the second instruction is prohibited from being received or triggered or selected; and in the draining stage, the first instruction is prohibited from being received or triggered or selected.

[0071] In the present embodiment, the washing apparatus has a cycle driving component and a draining driving component for providing power for the flow of washing water in the cycle operation and the draining operation respectively. In subsequent solutions of the present embodiment, a cycle pump 320 is used as the cycle driving component, and a draining pump 310 is used as the draining driving component, but it can be understood that other devices capable of providing water flow can also be used as the cycle driving component and the draining driving component in the present embodiment.

[0072] In the above scheme, the washing apparatus is controlled by a program such that the operations of circulating the washing water and draining the water are prohibited from being performed simultaneously, which is equivalent to controlling the circulation pump 320 and the drain pump 310 not to be allowed to run simultaneously, thereby avoiding the conflict between the circulating operation and the draining operation. In particular, the circulating operation performed when the water amount in the tub 100 is reduced is avoided, and the problem of air coexistence in the circulation pump 320 and the generation of a circulating abnormal sound are avoided. The washing apparatus only needs to modify the control program, and no improvement in the structure of the washing apparatus is required, and thus the implementation is easy.

[0073] On the other hand, since the circulation pipeline and the drain pipeline of the washing apparatus share a part of the pipeline structure, the program is controlled such that the circulating operation and the draining operation are not allowed to be performed simultaneously, and the problem of interference between the washing water flowing along the circulation pipeline and the drain pipeline is also prevented.

[0074] In a specific scheme of the embodiment, the washing apparatus further includes a power supply module, which is connected to the circulation pump 320 and the drain pump 310, respectively, for supplying power to the two pumps. The main control module of the washing apparatus controls the power supply module to supply power to the circulation pump 320 and the drain pump 310 selectively, thereby realizing that the two pumps cannot run simultaneously.

[0075] In the above scheme, the selective power supply of the power supply module to the circulation pump 320 and the drain pump 310 means that at the same time, the power supply module supplies power to at most one of the two pumps, and can not supply power to both of the two pumps.

[0076] In the embodiment, the washing apparatus controls the circulation pump 320 and the drain pump 310 not to be supplied with power simultaneously, thereby ensuring that the circulating operation and the draining operation do not conflict.

[0077] Further, in the scheme of the embodiment, the circulation pump 320 is allowed to be started only in a stage other than the draining stage of the washing program, and during the draining stage, the first instruction for starting the circulation pump 320 is prohibited from being received or triggered or selected, thereby effectively avoiding the conflict between the circulating operation and the draining operation.

[0078] In the embodiment, the washing program run by the washing apparatus includes at least a washing process, a rinsing process, and a final dehydration process, which are performed sequentially. The washing process further includes a washing water filling stage, a washing stage, a washing water draining stage, and a washing dehydration stage. The rinsing process includes at least one, and usually includes at least two rinsing cycles. Each rinsing cycle further includes a rinsing water filling stage, a rinsing stage, a rinsing water draining stage, and a rinsing dehydration stage. The draining stage in the embodiment includes the washing water draining stage and the rinsing water draining stages.

[0079] In a further solution, when the washing appliance performs the water inlet operation to fill the tub 100 with water, the control unit controls the water inlet operation to be performed until a certain amount of water is reached in the tub 100, and then the circulation of the washing water is started.

[0080] In particular, if the washing appliance receives a first instruction triggered by the user during the water inlet operation, the control unit controls whether to start the circulation pump 320 depending on the water level in the tub 100 or the duration of the water inlet operation. If the washing appliance automatically triggers the first instruction, the control unit controls the water inlet operation to be performed until a certain amount of water is reached in the tub 100, and then the first instruction is triggered.

[0081] As a specific implementation, the washing appliance detects the water level in the tub 100 during the water inlet operation, and when the water level in the tub 100 reaches a predetermined water level, the control unit starts the circulation pump 320 to start the circulation of the washing water.

[0082] As another specific implementation, the washing appliance starts timing after starting the water inlet operation, and when the water inlet operation lasts for a first predetermined duration, the control unit starts the circulation pump 320 to start the circulation of the washing water.

[0083] As still another specific implementation, the washing appliance keeps the circulation pump 320 closed during the water inlet operation, and after the water inlet operation is completed, the control unit starts timing and starts the circulation pump 320 to start the circulation of the washing water when a second predetermined duration is reached.

[0084] With the above solutions, it can be ensured that the circulation pump 320 is started to circulate the washing water after a certain amount of water is reached in the tub 100, thereby further avoiding the circulation of the washing water when the amount of water in the tub 100 is small, and thus the problem of abnormal sound during the circulation of the washing water is avoided.

[0085] In a further solution of the present embodiment, when the washing appliance runs a washing program, if a program pause instruction is received, the control unit controls the circulation pump 320 to be closed if the circulation pump 320 is currently in operation. After the washing appliance receives a continue running instruction, the control unit triggers a first instruction and controls the circulation pump 320 to be restarted according to the first instruction.

[0086] In the above solution, the circulation pump 320 is controlled to be closed when the washing program is paused, and the circulation pump 320 is restarted when the washing program is started again. It can be understood that if the washing appliance receives a program pause instruction and the circulation pump 320 is closed, the circulation pump 320 does not need to be started when the washing program is started again, and thus the first instruction is not triggered.

[0087] Further, after the washing appliance receives a continue running instruction, the control unit first determines whether a draining operation needs to be performed when the washing program is started again, and then controls whether the first instruction is allowed to be triggered.

[0088] As a specific embodiment, the washing apparatus receives the continue instruction, and determines whether the washing program paused before is running to the draining stage. If the result is yes, the second execution is triggered, and the draining pump 310 is started to drain. During the draining, the first instruction is prohibited from being triggered.

[0089] For example, the washing apparatus receives the program pause instruction just before a draining stage starts, and controls the circulating pump 320 to be closed. When the program is started again, the draining stage is started, and the draining pump 310 is started to drain. In this case, the washing apparatus does not trigger the first instruction when receiving the continue instruction, and the circulating pump 320 remains closed. Preferably, the first instruction can be triggered to start the circulating pump 320 after the draining pump 310 is closed and the washing apparatus is filled with water again.

[0090] Alternatively, some washing apparatuses perform draining operation and then re-filling to continue running when the program pause time exceeds a threshold. Specifically, for the case that the washing apparatus receives the program pause instruction and closes the circulating pump 320, when the washing apparatus receives the continue instruction, if it is determined that the program pause time is greater than the threshold, the draining pump 310 is started to perform the draining operation. During the draining operation, the first instruction is prohibited from being triggered, and the circulating pump 320 remains closed. After the draining operation ends and the draining pump 310 is closed, and the washing apparatus is filled with water again, the first instruction can be triggered to start the circulating pump 320.

[0091] Further, in a specific scheme of the embodiment, the circulating pump 320 is started each time and continues to run until the washing program runs to the next draining stage, or the washing program is paused or ended. Alternatively, the circulating pump 320 is started each time and continues to run for a set time, and then is closed, and will not be started again in the current program stage. That is, the circulating operation is set to be continuously performed in the washing stage, and optionally, in the rinsing stage.

[0092] In another specific scheme of the embodiment, in a complete washing stage or a complete rinsing stage, if the circulating operation needs to be performed, the circulating pump 320 is started intermittently during the running of the washing stage or the rinsing stage. That is, the circulating operation is set to be intermittently performed in a complete washing stage, and optionally, in a complete rinsing stage.

[0093] The washing apparatus in the embodiment also has a filtering device 600 arranged on the circulating pipeline. When the washing water flows along the circulating pipeline, it can circulate through the filtering device 600, so as to realize the circulating filtration of the washing water. The draining pipeline does not pass through the filtering device 600, that is, the washing water is not filtered when it is drained out, but is directly drained out without filtration.

[0094] As a specific structure, one end of the circulation pipe 220 is connected with the water outlet end of the circulation pump 320, and the other end is connected at the water inlet 6101 of the filter device 600, so as to send the washing water into the filter device 600. The washing water is filtered inside the filter device 600, and the filtered washing water is discharged from the filtered water outlet 6102. One end of the backwater pipe 250 is connected with the filtered water outlet 6102, and the other end is connected on the window pad 110, so as to send the filtered washing water back into the tub 100.

[0095] In the above scheme, the washing appliance is provided with the filter device 600, so that the washing water can be circulated and filtered during the running of the washing program, and the lint falling off the clothes can be removed from the water, so that the surface of the clothes is not attached with lint after the washing of the clothes is completed, and the user experience is improved.

[0096] The circulation pipeline and the drainage pipeline in the washing appliance share the pump hose 210, so that only one opening structure is required to be arranged at the bottom of the tub 100. The filter device 600 is arranged between the circulation pipe 220 and the backwater pipe 250 in the circulation pipeline, and the washing water is not discharged through the filter device 600, so that the drainage efficiency is not affected.

[0097] In a further scheme of the embodiment, the washing appliance determines the duration of circulating the washing water during the current washing program according to the type of the current running washing program.

[0098] In the above scheme, the duration of circulating the washing water refers to the total duration of the running of the circulation pump 320 in one complete washing stage or rinsing stage.

[0099] Specifically, for the scheme that the circulation pump 320 is continuously running in one washing stage or rinsing stage, the duration of circulating the washing water is the continuous running duration after the circulation pump 320 is turned on. For the scheme that the circulation pump 320 is intermittently turned on, the duration of circulating the washing water is the total running duration of the circulation pump 320 in the current washing stage or rinsing stage.

[0100] It should be noted that when the washing appliance performs the circulation operation in the washing stage and the rinsing stage, the respective execution durations of the circulation operation in the washing stage and the rinsing stage can be the same or different.

[0101] The washing apparatus of the embodiment can filter out the lint and other impurities in the washing water by performing the circulating operation, thereby ensuring the efficiency of filtering out the lint. When the washing apparatus runs different types of washing programs, the content of the lint in the washing water varies due to different washing intensity or corresponding clothing material. In order to ensure sufficient filtering of the lint and ensure that there is no lint left on the surface of the clothing after the washing is completed, the duration of the circulating operation needs to be matched with the content of the lint in the washing water.

[0102] For example, when the washing apparatus runs a gentle washing program, the friction force on the clothing is not large due to the relatively low washing intensity, and the lint is not easy to generate. The duration of circulating the washing water, i.e., the total duration of the operation of the circulating pump 320, can be set to be short. When the washing apparatus runs a wool washing program or a similar washing program suitable for the material of the clothing with dropped lint, the duration of circulating the washing water, i.e., the total duration of the operation of the circulating pump 320, can be set to be longer. When the washing apparatus runs a large washing program, a strong washing program or other washing programs with large washing intensity, the duration of circulating the washing water, i.e., the total duration of the operation of the circulating pump 320, can also be set to be longer.

[0103] As a specific embodiment, after the washing apparatus is started, the setting instruction of the user for the washing program is received, the type of the washing program to be run is determined, and the duration of circulating the washing water is matched according to the type of the washing program. After the washing program is started, the washing apparatus controls the opening and closing of the circulating pump 320 during the operation of the washing program according to the duration.

[0104] Through the above scheme, the circulating filtering effect of the washing water is ensured, the lint in the water can be filtered out sufficiently, and unnecessary long-time operation of the circulating pump 320 is reduced. In this way, the duration of the circulation is shortened as much as possible under the condition of ensuring the efficiency of filtering out the lint, unnecessary energy consumption and operation loss of the circulating pump 320 are avoided.

[0105] In the embodiment, the washing apparatus is controlled by the program so that the circulating operation of the washing water and the draining operation are prohibited from being run at the same time. Without structural improvement, the conflict between the circulating operation and the draining operation is prevented, and the problem of the circulating abnormal sound is avoided. The washing apparatus can filter out the lint on the surface of the clothing through the circulating operation, thereby improving the user experience.

[0106] Embodiment Two

[0107] As shown in FIG. 5, the control method of the washing apparatus provided in the embodiment is different from the above-mentioned embodiment one in that after the washing apparatus receives one of the first instruction and the second instruction, it is first determined whether the other instruction is being executed. If yes, the received instruction is invalid.

[0108] In this embodiment, the received instruction is invalid, that is, the washing appliance does not execute the received instruction and does not run the corresponding work, which is equivalent to ignoring the received instruction.

[0109] Further, if it is judged that another instruction is not currently executed, the received instruction can be executed.

[0110] As a specific embodiment, when a cycle button and a drain button are arranged on the operation panel of the washing appliance, the two buttons can be operated by the user regardless of whether the washing appliance is executing a cycle operation or a drain operation, and the corresponding first instruction / second instruction is generated and sent to the main control module of the washing appliance. After receiving the instruction, the main control module judges whether another instruction is being executed, and then determines whether to execute or ignore the received instruction.

[0111] Specifically, after the washing appliance receives the first instruction, it is judged whether the washing appliance is draining. If yes, the received first instruction is invalid, and the washing appliance will not perform the cycle operation. If the washing appliance is not draining, the cycle washing water can be started.

[0112] Similarly, after the washing appliance receives the second instruction, it is judged whether the washing appliance is performing the cycle washing water. If yes, the received second instruction is invalid, and the washing appliance will not perform the drain operation. If the cycle washing water is not currently performed, the drain can be started.

[0113] In a more specific scheme, in combination with FIGS. 1-3, the washing appliance of the present embodiment judges whether the washing appliance is performing the cycle washing water / drain by obtaining the working state of the cycle pump 320 / drain pump 310.

[0114] Specifically, after the washing appliance receives the first instruction, the working state of the drain pump 310 is first obtained. If the drain pump 310 is running, the received first instruction is invalid. If the drain pump 310 is in the closed state, the first instruction can be executed, and the cycle pump 320 is started to perform the cycle washing water.

[0115] In the above scheme, the cycle pump 320 is only allowed to be started in the stages other than the drain stage of the washing program, and if the first instruction for starting the cycle pump 320 is received during the drain stage, the first instruction will be ignored and not executed, effectively avoiding the problem of conflict between the cycle operation and the drain operation.

[0116] When the washing appliance receives the second instruction, the working state of the cycle pump 320 is obtained. If the cycle pump 320 is running, the received second instruction is invalid. If the cycle pump 320 is in the closed state, the second instruction can be executed, and the drain pump 310 is started to perform the drain.

[0117] In this embodiment, after receiving any one of the first instruction and the second instruction, the washing equipment first determines whether the other instruction is being executed, and then controls whether to execute the received instruction. When the other instruction is being executed, the received instruction is invalid, which can effectively avoid the conflict between the circulating washing water and the drainage. In addition, for the case that the user manually triggers the first instruction and the second instruction through the operation panel, the response logic of the operation panel to the user operation is not changed, which is easy to implement.

[0118] Embodiment three

[0119] The control method of the washing equipment provided in this embodiment is different from the above-mentioned embodiment two in that: when the washing equipment receives one of the first instruction and the second instruction and determines that the other instruction is being executed, the washing equipment waits until the execution of the other instruction is completed, and then executes the received instruction.

[0120] Specifically, as shown in FIG. 6, in this embodiment, after the washing equipment receives one of the first instruction and the second instruction, the washing equipment determines whether the other instruction is being executed. If the determination result is no, the washing equipment executes the received instruction. If the determination result is yes, the washing equipment waits until the execution of the other instruction is completed, and then executes the received instruction.

[0121] More specifically, after the washing equipment waits until the execution of the being-executed instruction is completed, the washing equipment can automatically execute the received instruction without the need for the user or the washing program to trigger the instruction again.

[0122] As a specific implementation, the operation panel of the washing equipment is provided with a circulating button and a drainage button. When the user operates the above-mentioned two buttons, the corresponding first instruction or second instruction can be triggered and sent to the main control module of the washing equipment. After receiving the instruction, the main control module determines whether the other instruction is being executed, and then determines whether to allow the received instruction to be executed immediately.

[0123] In the specific scheme of this embodiment, after the washing equipment receives the first instruction, the washing equipment determines whether the washing equipment is being drained. If yes, the washing equipment does not immediately perform the circulating operation, but waits until the current drainage operation is completed, and then starts the circulating washing water. If the washing equipment is not being drained, the washing equipment can start the circulating washing water.

[0124] Similarly, after the washing equipment receives the second instruction, the washing equipment determines whether the washing equipment is being circulated. If yes, the washing equipment does not immediately perform the drainage operation, but waits until the current circulating operation is completed, and then starts to drain externally. If there is no circulating washing water, the washing equipment can immediately start to drain.

[0125] Similar to the above embodiment two, the washing apparatus of the present embodiment determines whether the washing apparatus is circulating the washing water / drainage by acquiring the working state of the circulating pump 320 / the drainage pump 310.

[0126] Specifically, after receiving the first instruction, the washing apparatus first acquires the working state of the drainage pump 310. If the drainage pump 310 is in the closed state, the first instruction can be executed, and the circulating pump 320 is started to begin circulating the washing water. If the drainage pump 310 is running, the circulating pump 320 is not allowed to be started immediately, but waits until the drainage operation is completed, and the drainage pump 310 is closed, and then the circulating pump 320 is started.

[0127] More specifically, when the washing apparatus receives the first instruction and determines that the drainage pump 310 is in the running state, the drainage pump 310 is kept running until the drainage is completed, and the drainage pump 310 is controlled to be closed. Then, the washing apparatus continues to run the subsequent stage according to the preset progress of the washing program, for example, first performs dehydration, and then performs water filling again. After the washing apparatus starts to perform the water filling operation, so that the tub 100 has a certain amount of water, the received first instruction is executed, and the circulating pump 320 is started to begin circulating the washing water.

[0128] Alternatively, if the washing apparatus performs the drainage operation only to discharge a certain amount of washing water, but not to empty the tub 100, after the drainage is completed and the drainage pump 310 is controlled to be closed, the washing apparatus can directly start the circulating pump 320 to begin circulating the washing water.

[0129] When the washing apparatus receives the second instruction, the working state of the circulating pump 320 is first acquired. If the circulating pump 320 is running, the circulating pump 320 is kept in the running state until the circulation operation is completed, and then the second instruction is executed, that is, the drainage pump 310 is started to discharge water. If the circulating pump 320 is in the closed state, the second instruction can be directly executed, and the drainage pump 310 is started to begin drainage.

[0130] In the present embodiment, if the received instruction conflicts with the instruction being executed, the instruction is executed in sequence, that is, after the execution of the currently executed instruction is completed, the received instruction is executed. By using the scheme provided in the present embodiment, the instruction being executed by the washing apparatus, that is, the current working process, will not be interrupted, especially, the drainage operation will not be interrupted to directly perform circulation, which avoids interrupting the drainage operation to directly perform circulation when most of the washing water in the tub 100 is discharged, and the problem of abnormal sound caused by too little water during circulation.

[0131] Embodiment four

[0132] The embodiment provides a control method of a washing device, which is different from the third embodiment in that the washing device receives one of a first instruction and a second instruction, and interrupts execution of the other instruction when it is determined that the other instruction is being executed, and executes the received instruction first.

[0133] Specifically, as shown in FIG. 7, in the embodiment, after the washing device receives one of a first instruction and a second instruction, it is determined whether the other instruction is being executed. If the determination result is no, the received instruction is executed. If the determination result is yes, the execution of the other instruction is interrupted, the received instruction is executed first, and then the other instruction is executed after the execution of the received instruction is completed.

[0134] As a specific embodiment, after the execution of the received instruction is completed, the washing device does not need to receive the other instruction again, and can automatically resume the operation of the other instruction. That is, the user does not need to operate the washing device again to trigger the instruction that is interrupted, and the washing device also does not automatically trigger the other instruction to be sent to the main control module after the execution of the received instruction is completed.

[0135] As another specific embodiment, after the execution of the received instruction is completed, the main control module of the washing device receives the other instruction, so as to control the execution of the other instruction.

[0136] Specifically, the main control module of the washing device waits for the user to trigger the other instruction, and then controls the execution of the other instruction.

[0137] For example, in a specific scheme, after the washing device completes the operation of the received instruction, it waits for the user to trigger the other instruction, and then operates the other instruction after receiving the other instruction triggered by the user. More specifically, the way in which the user triggers the other instruction can be to trigger the key corresponding to the other instruction on the operation panel.

[0138] In the scheme of the embodiment, after the washing device receives an instruction that conflicts with the instruction being executed at present, it can interrupt the execution of the current instruction, execute the received instruction first, and then execute the other instruction that is interrupted after the execution of the received instruction is completed. In this way, the received instruction can be responded more timely, and the conflict between the operations corresponding to the two instructions can be avoided.

[0139] In the embodiment, the interruption of the execution of the current instruction can be to suspend the execution of the instruction, that is, after the execution of the received instruction is completed, the suspended instruction continues to execute the remaining part, or the execution of the instruction can be directly stopped, that is, after the execution of the received instruction is completed, the stopped instruction is re-operated from the beginning.

[0140] Further, in one specific implementation of the embodiment, after receiving one of the first instruction and the second instruction, the washing appliance determines whether the other instruction is being executed. If so, the execution of the other instruction is suspended, and the received instruction is executed first. After the execution of the received instruction is completed, the washing appliance continues to execute the other instruction from the suspended node.

[0141] More specifically, after receiving the first instruction, if it is determined that the draining is being performed, the washing appliance suspends the draining operation and starts the circulating of the washing water. After the circulating of the washing water is completed, the washing appliance continues to drain the washing water outwards.

[0142] In combination with FIGS. 1-3, as one specific solution, after receiving the first instruction, the washing appliance acquires the working state of the draining pump 310. If the draining pump 310 is in the off state, the first instruction is executed directly, and the circulating pump 320 is started to circulate the washing water. If the draining pump 310 is in the running state, the draining pump 310 is controlled to be turned off first, so that the draining is suspended, and then the circulating pump 320 is started. After the circulating pump 320 runs for a period of time, the circulating operation is completed, and the circulating pump 320 is turned off. At this time, the draining pump 310 is started again, and the draining of the washing water outwards is continued.

[0143] In a preferred solution, after the draining is suspended, the washing appliance acquires the water level in the tub 100. If the water level is not lower than a preset water level, the first instruction is executed. Otherwise, the execution of the first instruction is prohibited.

[0144] Specifically, when the washing appliance receives the first instruction and acquires that the draining pump 310 is in the running state, the draining pump 310 is controlled to be turned off first, and then the water level in the tub 100 is detected. If the water level is not lower than a preset water level, the first instruction is executed, and the circulating pump 320 is started. If the detected water level is lower than the preset water level, the circulating pump 320 is prohibited from being started, so as to avoid the circulating pump 320 from running to suck in air and generate a circulating abnormal sound.

[0145] In a further solution, the second instruction is to drain a preset amount of washing water in the tub 100, instead of draining all the washing water in the tub 100. After receiving the second instruction, if it is determined that the washing water is being circulated, the washing appliance suspends the circulating and starts the draining. When the drained amount of washing water reaches the preset amount, the draining is completed, and the washing appliance continues to perform the circulating operation.

[0146] It can be understood that the preset amount should be lower than the actual water capacity of the tub 100.

[0147] In detail, after receiving the second instruction, the washing appliance acquires the working state of the circulating pump 320. If the circulating pump 320 is in the closed state, the second instruction is directly executed to start the drain pump 310 to begin draining. If the circulating pump 320 is in the running state, the circulating pump 320 is first controlled to be closed, so that the circulation of the washing water is temporarily suspended, and then the drain pump 310 is started. The drain pump 310 continuously runs for a period of time, so that when the amount of water drained reaches the preset amount, the current draining operation ends, the drain pump 310 is closed, and at this time the washing appliance starts the circulating pump 320 to continue circulating the remaining washing water. The running time of the circulating pump 320 after being restarted should be the total time of the current circulation operation set by the program minus the time of the circulation before the draining starts.

[0148] In another specific implementation of the embodiment, after the washing appliance receives one of the first instruction and the second instruction, it is determined whether the other instruction is being executed. If so, the execution of the other instruction is stopped, and the received instruction is executed first. After the execution of the received instruction is completed, the washing appliance re-executes the other instruction.

[0149] Specifically, after receiving the second instruction, if it is determined that the washing water is being circulated, the draining operation is stopped, and the draining is started. After the draining ends, the washing appliance re-starts the circulation operation. More specifically, in combination with FIGS. 1 to 3, after the draining operation ends and the water level in the tub 100 is not lower than the preset water level, the washing appliance re-starts the circulation of the washing water.

[0150] As a specific scheme, after receiving the second instruction, the washing appliance acquires the working state of the circulating pump 320. If the circulating pump 320 is in the closed state, the second instruction can be directly executed to start the drain pump 310 to drain water outward. If the circulating pump 320 is in the running state, the circulating pump 320 is controlled to be closed, and then the drain pump 310 is started to drain water. After the draining ends, the washing appliance re-fills water to a certain amount, and then starts the circulating pump 320 to re-circulate.

[0151] As another specific scheme, the second instruction is to drain a preset amount of washing water in the tub 100, and the preset amount is lower than the actual water capacity of the tub 100. After receiving the second instruction, if it is acquired that the circulating pump 320 is in the running state, the circulating pump 320 is controlled to be closed, and then the drain pump 310 is started to drain water. The drain pump 310 continuously runs for a period of time, so that when the amount of water drained reaches the preset amount, the current draining operation ends, the drain pump 310 is closed, and at this time the washing appliance re-starts the circulating pump 320 to circulate the remaining washing water. The running time of the circulating pump 320 after being restarted should be the total time of the current circulation operation set by the program.

[0152] In the embodiment, the washing apparatus interrupts the execution of the other instruction and executes the received instruction preferentially if it is determined that the other instruction is being executed after receiving one of the first instruction and the second instruction, so that the washing apparatus has a more timely response to the received instruction. After the execution of the received instruction is completed, the washing apparatus executes the other instruction that is interrupted, so that the integrity of the work is ensured.

[0153] Embodiment Five

[0154] The embodiment is a further limitation of the above-mentioned embodiment four, the first instruction and the second instruction have different priorities, and the washing apparatus controls the execution sequence according to the priorities of the two instructions.

[0155] Specifically, as shown in FIG. 8, in the embodiment, the washing apparatus receives one of the first instruction and the second instruction, and then determines whether the other instruction is being executed. If the other instruction is not being executed, the received instruction can be executed directly.

[0156] However, if the other instruction is being executed, it is further determined whether the received instruction has a higher priority. If yes, the execution of the other instruction is interrupted, and the received instruction is executed preferentially. Otherwise, the received instruction is executed after the execution of the other instruction is completed.

[0157] Further, when the received instruction has a higher priority, the received instruction is executed preferentially, and the other instruction is executed after the execution of the received instruction is completed. Specifically, when the received instruction has a higher priority, the subsequent control flow can be the same as any of the specific embodiments in embodiment four.

[0158] As a specific embodiment of the embodiment, the priority of the second instruction is higher than that of the first instruction in the master control module of the washing apparatus. Generally, the drainage operation needs to be performed more timely, so that setting the second instruction to have a higher priority is more consistent with the actual working condition of the washing apparatus.

[0159] Specifically, after the washing apparatus receives the first instruction, if it is determined that the drainage is being performed, the washing apparatus waits until the drainage is completed, and then performs the circulation of the washing water. If the washing apparatus receives the second instruction and it is determined that the circulation of the washing water is being performed, the washing apparatus interrupts the circulation of the washing water, performs the drainage preferentially, and then performs the circulation operation after the drainage is completed.

[0160] In combination with FIGS. 1 to 3, in a specific scheme, after the washing apparatus receives the first instruction, the working state of the drainage pump 310 is acquired. If the working state is the closed state, the circulation pump 320 is directly started to perform the circulation of the washing water. If the working state of the drainage pump 310 is the running state, the drainage pump 310 is controlled to continue running, and the circulation pump 320 remains in the closed state. When the drainage pump 310 is closed, the circulation pump 320 is started, or the circulation pump 320 is started after the washing apparatus is refilled with water.

[0161] When the washing apparatus receives the second instruction, the working state of the circulating pump 320 is acquired. If it is in the off state, the draining pump 310 is directly started to drain. If the circulating pump 320 is in the running state, the circulating pump 320 is turned off, and then the draining pump 310 is started to drain. After the draining is completed, the draining pump 310 is turned off. If the water tub 100 is emptied or nearly emptied by this time, the circulating pump 320 is started again after a certain amount of water is added. If only part of the washing water is drained by this time, the circulating pump 320 is directly started again to circulate the washing water after the water level in the water tub 100 is not lower than the preset water level.

[0162] As another specific embodiment of the present embodiment, the washing apparatus determines the priority of the first instruction and the second instruction according to the setting of the user.

[0163] For example, in one specific scheme, the user can set the priority of the first instruction and the second instruction through the operation panel of the washing apparatus, so as to flexibly set one of the two instructions to have a higher priority according to the use habit or demand.

[0164] Preferably, the user can also change the priority of the first instruction and the second instruction. For example, the user sets the priority of the first instruction to be higher than that of the second instruction in a certain period of time, and after a period of time, the use habit of the user changes, and the user can also reset the priority so that the second instruction has a higher priority.

[0165] In one specific embodiment, the user sets the priority of the first instruction to be higher than that of the second instruction, and the washing apparatus operates as follows.

[0166] After the washing apparatus receives the first instruction, the working state of the draining pump 310 is acquired. If it is in the off state, the circulating pump 320 is directly started to circulate the washing water. If the draining pump 310 is in the running state, the draining pump 310 is controlled to be turned off, and then the circulating pump 320 is started to start circulating the washing water. The circulating pump 320 continuously operates until the present circulating operation is completed, and then the circulating pump 320 is turned off. At this time, the washing apparatus starts the draining pump 310 again to continue draining.

[0167] When the washing apparatus receives the second instruction, the working state of the circulating pump 320 is acquired. If it is in the off state, the draining pump 310 is directly started to drain. If the circulating pump 320 is in the running state, the circulating pump 320 is controlled to continue running, and the draining pump 310 remains in the off state. When the circulating operation is completed, the circulating pump 320 is turned off, and then the draining pump 310 is started to start draining.

[0168] In a preferred solution of the embodiment, the washing device defaults the priority of the second instruction to be higher than the first instruction, but also provides a function for the user to set the priority of the two instructions autonomously.

[0169] That is, in the default state, if the first instruction is received during the draining process of the washing device, the first instruction needs to be executed after the current draining process is completed. If the second instruction is received during the washing water circulating process, the circulating operation is interrupted, the second instruction is executed first to drain, and then the washing water is circulated or recirculated after the draining process is completed.

[0170] However, if the user sets the priority of the first instruction and the second instruction autonomously, when the received first instruction or second instruction conflicts with the instruction being executed, the execution order of the instruction being executed and the received instruction is controlled according to the priority set by the user.

[0171] In the embodiment, by setting the first instruction and the second instruction to have different priorities, it can be ensured that one of the instructions is always executed preferentially, which is suitable for the actual working condition that the circulating washing water and the draining process have different priorities.

[0172] Embodiment Six

[0173] As shown in FIGS. 1-3, the embodiment is a further limitation of any of the above embodiments, and the filter device 600 includes a filter housing 610 and a filter cartridge 620 arranged inside the filter housing 610. The filter device 600 uses a filter cartridge 620 to filter the unfiltered washing water from the outside of the filter cartridge 620 and discharge the filtered water from the inside of the filter cartridge 620.

[0174] Specifically, the filter housing 610 is provided with a water inlet 6101 and a filtered water outlet 6102, and the filter cartridge 620 divides the inside of the filter housing 610 into an outer cavity and an inner cavity. The water inlet 6101 communicates with the outer cavity, and the filtered water outlet 6102 communicates with the inner cavity. The unfiltered washing water enters the outer cavity through the water inlet 6101, passes through the filter cartridge 620 to enter the inner cavity to be filtered, and the lint carried in the water adheres to the outer wall of the filter cartridge 620, and the water filtered of the lint flows out through the filtered water outlet 6102.

[0175] More specifically, one end of the filter cartridge 620 is provided with a water outlet connector 621 extending along the axis thereof, and the water outlet connector 621 is sealingly inserted into the filtered water outlet 6102, so that the filtered water in the filter cartridge 620 flows out through the filtered water outlet 6102 through the water outlet connector 621.

[0176] As a specific structure, the filter cartridge 620 can be a hard cylindrical structure, and a plurality of filter holes are directly formed on the filter cartridge 620. As another specific structure, the filter cartridge 620 includes a hollow structure support, and a filter screen covering the support, the filter screen covering at least the hollow part of the support, and the filter screen having filter holes.

[0177] In further schemes of the embodiment, the filter device 600 has a self-cleaning function, and can autonomously clean and discharge the accumulated wire scraps inside, avoiding the trouble of manual cleaning by the user.

[0178] Specifically, the filter cartridge 620 is rotatably arranged inside the filter housing 610, and the water outlet joint 621 is rotatably inserted and matched with the filtered water outlet 6102. The filter device 600 further includes a driving mechanism 660 for driving the filter cartridge 620 to rotate in the filter housing 610. The filter housing 610 is provided with a wire scrap discharge outlet 6103. The filter cartridge 620 is driven to rotate by the driving mechanism 660, the wire scraps attached to the outer wall of the filter cartridge 620 are stripped, the wire scraps are discharged from the wire scrap discharge outlet 6103, and the self-cleaning of the filter device 600 is realized.

[0179] The driving mechanism 660 can be an electric motor arranged outside the filter housing 610. As a specific embodiment, the axis of the filter cartridge 620 extends in a horizontal or nearly horizontal direction, the water inlet 6101 is arranged at the top of the filter housing 610, the wire scrap discharge outlet 6103 is arranged at the bottom of the filter housing 610, the filtered water outlet 6102 is arranged at one end of the filter housing 610, and the driving mechanism 660 is arranged outside the other end of the filter housing 610.

[0180] In another embodiment, the filter device can also be installed according to the orientation that the axis of the filter cartridge extends in a vertical or nearly vertical direction. When the filter device is installed with the filter cartridge arranged vertically, the filtered water outlet is arranged at the lower end of the filter housing.

[0181] When the wire scraps accumulated inside the filter device 600 need to be cleaned, the filter cartridge 620 is driven to rotate by the driving mechanism 660, the residual accumulated water in the filter housing 610 is agitated, the wire scraps attached to the outer wall of the filter cartridge 620 are stripped under the dual action of centrifugal force and turbulent water flow, mixed into the accumulated water in the filter housing 610, and then the wire scrap water mixed with the wire scraps can be discharged through the wire scrap discharge outlet 6103.

[0182] In further schemes, the wire scrap discharge outlet 6103 is connected with a sewage pipe 240, and a sewage valve 241 is arranged on the sewage pipe 240 for controlling the on-off of the sewage pipe 240.

[0183] When the washing apparatus performs a cycle, the drain valve 241 is controlled to be closed, and the drain pipe 240 is cut off, so that water cannot continuously drain out of the filter device 600 through the lint outlet 6103, and the washing water entering the filter device 600 can be filtered by the filter cylinder 620 and then return to the tub 100 through the backwater pipe 250. When it is necessary to drain the lint, the drain valve 241 is opened to connect the drain pipe 240, and the water mixed with the lint in the filter housing 610 can be drained out of the lint outlet 6103 and then through the drain pipe 240.

[0184] In a further aspect of the embodiment, the outlet end of the drain pipe 240 is connected to the drain pipe 230 of the washing apparatus, so that the water mixed with the lint can be sent to the drain pipe 230 and then drained out of the washing apparatus through the drain pipe 230. In a specific structure, the outlet end of the drain pipe 240 is connected to the drain pipe 230 at a position close to the outlet of the drain pipe 230.

[0185] As a specific embodiment, the washing apparatus adopts an upper drain structure, and the drain pipe 230 extends from the outlet end of the drain pump 310 to the rear side of the tub 100, and then extends rearward of the tub 100 to the outside of the cabinet of the washing apparatus from a position higher than the highest water level in the tub 100. The drain pipe 240 is connected to the region of the drain pipe 230 extending upward.

[0186] With the above structure, the washing apparatus opens the drain valve 241 during the drain stage of the washing program, i.e., during the process of performing the drain operation, so that the water mixed with the lint is drained into the drain pipe 230 through the drain pipe 240, and then the lint can be carried by the drain water and drained out of the washing apparatus.

[0187] In a preferred aspect of the embodiment, the drain valve 241 is opened at the beginning of the drain stage, so that the lint can be prevented from remaining in the drain pipe 230 after the washing apparatus ends the operation.

[0188] In the embodiment, the washing apparatus first starts the driving mechanism 660 to drive the filter cylinder 620 to rotate in the filter housing 610 for a period of time to realize self-cleaning of the filter device 600. Then, if it is necessary to remove the lint, the drain valve 241 is opened to drain the lint together with the accumulated water in the filter housing 610.

[0189] The driving mechanism 660 can be kept in the running state after the drain valve 241 is opened, so that the filter cylinder 620 continues to rotate during the period of draining the lint. Alternatively, the driving mechanism 660 can be closed before or after the drain valve 241 is opened, so that the filter cylinder 620 remains stationary during the period of draining the lint.

[0190] In this embodiment, the self-cleaning action of rotating the filter cartridge 620 driven by the driving mechanism 660 and / or the dirt discharging action of opening the dirt discharging valve 241 to discharge the wire scraps are performed at least once in a complete washing procedure.

[0191] As a first specific implementation, the washing apparatus performs the self-cleaning action before or during the subsequent draining stage after each cycle operation, and performs the dirt discharging action in the last draining stage.

[0192] As a second specific implementation, the washing apparatus performs the self-cleaning action before the last draining stage of the current washing procedure, and performs the dirt discharging action after the last draining stage.

[0193] As a third specific implementation, the washing apparatus performs the self-cleaning action and the dirt discharging action in sequence in the subsequent draining stage after each cycle operation.

[0194] In one specific solution, the washing apparatus can determine the number of times of performing the self-cleaning action and the dirt discharging action in the current washing procedure according to the type of the current running washing procedure. If the wire scrap content in the water is large, the third specific implementation above can be adopted; if the wire scrap content is moderate, the first specific implementation above can be adopted; and if the wire scrap content is small, the second specific implementation above can be adopted.

[0195] Through the above solution, the filter device 600 can autonomously clean the wire scraps accumulated in the filtering process and directly discharge the cleaned wire scraps, avoiding the problem that the filter device 600 is blocked by the wire scraps and cannot realize the filtering function. The whole process does not require user intervention, saving the user the trouble of manual cleaning.

[0196] In a further solution of the embodiment, the filter housing 610 of the filter device 600 is further provided with cleaning particles 680 for rubbing and colliding with the inner wall of the filter housing 610 and the outer wall of the filter cartridge 620 along with the water flow.

[0197] Specifically, when the washing apparatus performs the cycle operation, the cleaning particles 680 constantly rub the inner wall of the filter housing 610 and the outer wall of the filter cartridge 620 along with the flowing water flow, so that the attached wire scraps fall off, thereby preventing the wire scraps from depositing too fast and avoiding the problem that the filter cartridge 620 is quickly covered by the wire scraps, affecting the filtering efficiency. On the other hand, it also avoids the problem that after a long time of continuous cycle filtering, the attached wire scraps are thick, and are too firmly attached to the inner wall of the filter housing 610 or the outer wall of the filter cartridge 620, making it difficult to remove the attached wire scraps when the driving mechanism 660 drives the rotation of the filter cartridge 620.

[0198] Further, the filter housing 610 is provided with a baffle 690 inside, which divides the filter housing 610 into a first space on the left and a second space on the right. The baffle 690 is provided with a water hole 691 for communication between the first space and the second space. The water inlet 6101 is in communication with the first space, and the filtered water outlet 6102 and the lint outlet 6103 are in communication with the second space. The cleaning particles 680 are arranged in the first space, and the main body of the filter cartridge 620 is arranged in the first space.

[0199] During the filtering process, the cleaning particles 680 are continuously rubbed against the inner wall of the filter housing 610 and the outer wall of the filter cartridge 620 in the first space, so that the attached lint is removed. When the filter cartridge 620 rotates in the filter housing 610, the cleaning particles 680 move in the filter housing 610 under the action of the turbulent water flow, and rub against the inner wall of the filter housing 610 and the outer wall of the filter cartridge 620, which can improve the peeling efficiency of the impurities. When the lint and water are discharged, the lint and water can enter the second space through the water hole 691 on the baffle 690, and then be discharged through the lint outlet 6103. The cleaning particles 680 cannot pass through the water hole 691, and are intercepted by the baffle 690 in the first space on the left, so that the cleaning particles 680 are not discharged with the water flow through the lint outlet 6103, or the lint outlet 6103 is blocked, which affects the efficiency of discharging the lint.

[0200] In this embodiment, the filter device 600 can realize self-cleaning, and the lint cleaned can be directly discharged along the drain pipe 230, without the need for manual cleaning by the user, so that the problem of the filter device 600 being blocked by the lint and unable to realize the filtering function can be avoided. The arrangement of the cleaning particles 680 further improves the cleaning efficiency of the lint and ensures the filtering effect. By arranging the drain valve 241 to be opened during the drainage stage, the lint can be directly discharged by using the water flow, which effectively avoids the residue of the lint in the drain pipe 230.

[0201] Embodiment Seven

[0202] As shown in FIG. 9, the difference between this embodiment and any of the above embodiments is that the circulating driving component and the drainage driving component are integrated.

[0203] Specifically, in this embodiment, the pump hose 210 is connected to a pump assembly 330 with two outlets. The water inlet end of the pump assembly 330 is connected to the pump hose 210, the first water outlet end is connected to the circulating pipe 220, and the second water outlet end is connected to the drain pipe 230.

[0204] As a specific embodiment of the present embodiment, the circulating driving component is a circulating motor arranged in the pump assembly 330, and after the circulating motor is started, water in the water tank 100 can be pumped into the pump assembly 330 and discharged from the first water outlet of the pump assembly 330 and into the circulating pipe 220.

[0205] The water draining driving component is a water draining motor arranged in the pump assembly 330, and after the water draining motor is started, water in the water tank 100 can be pumped into the pump assembly 330 and discharged from the second water outlet of the pump assembly 330 and into the water draining pipe 230.

[0206] When the washing device has the above structure, the circulating motor and the water draining motor are not allowed to operate simultaneously through program control, so that the problem of conflict between the circulating operation and the water draining operation can be avoided.

[0207] As a specific embodiment, the power supply module of the washing device is connected with the circulating motor and the water draining motor respectively, and the main control module of the washing device controls the power supply module to supply power to the circulating motor and the water draining motor selectively, so that the two cannot operate simultaneously.

[0208] In the present embodiment, the washing device can perform the control method of the washing device provided in any one of embodiments one to five.

[0209] As a specific solution, after the washing device receives the first instruction, the circulating motor is started, and meanwhile the second instruction is prohibited from being received or triggered or selected, and the water draining motor will not be started. After the washing device receives the second instruction, the water draining motor is started, and meanwhile the first instruction is prohibited from being received or triggered or selected, and the circulating motor will not be started.

[0210] As another specific solution, after the washing device receives the first instruction, the working state of the water draining motor is acquired, if the water draining motor is in the closed state, the circulating motor is started, if the water draining motor is in the running state, the circulating motor is started after the water draining motor continues to run to the closed state, or the water draining motor is controlled to be closed first and then the circulating motor is started. After the washing device receives the second instruction, the working state of the circulating motor is acquired, if the circulating motor is in the closed state, the water draining motor is started, if the circulating motor is in the running state, the water draining motor is started after the circulating motor continues to run to the closed state, or the circulating motor is controlled to be closed first and then the water draining motor is started.

[0211] As another specific implementation of the embodiment, the pump assembly 330 is provided with a bidirectional driving motor, which is used as the circulating driving component and the draining driving component. When the driving motor is operated in the forward direction, the washing water entering the pump assembly 330 is drained from the first water outlet and into the circulating pipe 220. When the driving motor is operated in the reverse direction, the washing water entering the pump assembly 330 is drained from the second water outlet and into the draining pipe 230.

[0212] When the washing appliance has the above structure, as a specific solution, after the washing appliance receives the first instruction, the driving motor is controlled to be operated in the forward direction, and meanwhile the second instruction is prohibited from being received or triggered or selected. After the washing appliance receives the second instruction, the driving motor is controlled to be operated in the reverse direction, and meanwhile the first instruction is prohibited from being received or triggered or selected.

[0213] As another specific solution, after the washing appliance receives the first instruction, the working state of the driving motor is acquired. If the driving motor is in the off state, the driving motor is turned on and operated in the forward direction. If the driving motor is operated in the reverse direction, the driving motor is controlled to be operated in the forward direction after the current draining operation is completed, or the driving motor is turned off to interrupt the draining operation, and then the driving motor is turned on and operated in the forward direction. After the washing appliance receives the second instruction, the working state of the driving motor is acquired. If the driving motor is in the off state, the driving motor is turned on and operated in the reverse direction. If the driving motor is operated in the forward direction, the driving motor is controlled to be operated in the reverse direction after the current circulating operation is completed, or the driving motor is turned off to interrupt the circulating operation, and then the driving motor is turned on and operated in the reverse direction.

[0214] In the embodiment, the washing appliance uses the integrated pump assembly 330 to control the switching of the washing water flow direction in the circulating operation and the draining operation, and the same control logic is applicable to the control that the circulating operation and the draining operation are prohibited from being performed simultaneously, and the problem of circulating noise does not occur.

[0215] Embodiment Eight

[0216] As shown in FIG. 10, the embodiment is different from any of the above embodiments in that the circulating driving component and the draining driving component are the same water pump device 340, and the water outlet of the water pump device 340 is connected to the three-way switch valve 261, and the three-way switch valve 261 is used to control the circulation pipe 220 and the draining pipe 230 to be connected to the water pump device 340 alternatively.

[0217] Specifically, in the embodiment, the water outlet of the water pump device 340 is connected to one end of the water pump outlet pipe 260, the other end of the water pump outlet pipe 260 is connected to the inlet of the three-way switch valve 261, the first outlet of the three-way switch valve 261 is connected to the circulation pipe 220, and the second outlet of the three-way switch valve 261 is connected to the draining pipe 230.

[0218] When the washing apparatus performs a circulating operation, the inlet of the three-way switching valve 261 is controlled to be in communication with the first outlet, and the water pump device 340 is started, so that the washing water in the water tub 100 is driven to flow into the circulating pipe 220, and the circulating flow of the washing water is realized. When a draining operation is performed, the inlet of the three-way switching valve 261 is controlled to be in communication with the second outlet, and the water pump device 340 is started, so that the washing water in the water tub 100 is driven to flow into the draining pipe 230 and is drained out of the draining pipe 230.

[0219] The washing apparatus of the present embodiment has the above structure, and can also perform the control method of the washing apparatus provided in any one of Embodiments 1 to 5.

[0220] As a specific solution, after the washing apparatus receives the first instruction, the three-way switching valve 261 is controlled to be in a state of being in communication with the first outlet, and then the water pump device 340 is started, and at the same time, the second instruction is prohibited from being received or triggered or selected, so that the state of the three-way switching valve 261 cannot be changed. After the washing apparatus receives the second instruction, the three-way switching valve 261 is controlled to be in a state of being in communication with the second outlet, and then the water pump device 340 is started, and at the same time, the first instruction is prohibited from being received or triggered or selected, so that the state of the three-way switching valve 261 cannot be changed.

[0221] As another specific solution, after the washing apparatus receives the first instruction, the working state of the water pump device 340 is first acquired. If the water pump device 340 is in a closed state, the three-way switching valve 261 is controlled to be in a state of being in communication with the first outlet, and then the water pump device 340 is started, so that the circulating of the washing water is performed.

[0222] If the water pump device 340 is acquired to be in a running state, and the three-way switching valve 261 is further acquired to be in a state of being in communication with the second outlet, it is indicated that the draining is being performed. In this case, the washing apparatus keeps draining until the water pump device 340 is closed after the draining is completed, or the water pump device 340 is immediately controlled to be closed, and then the washing apparatus controls the three-way switching valve 261 to switch the communication state to be in communication with the first outlet, and then the water pump device 340 is restarted to perform the circulating of the washing water.

[0223] After the washing apparatus receives the second instruction, the working state of the water pump device 340 is first acquired. If the water pump device 340 is in a closed state, the three-way switching valve 261 is controlled to be in a state of being in communication with the second outlet, and then the water pump device 340 is started, so that the draining is performed.

[0224] If the water pump device 340 is in the running state and the three-way switch valve 261 is in the state of conducting the inlet and the first outlet, it is indicated that the washing water is being circulated. In this case, the washing apparatus continues the circulation operation until the water pump device 340 is closed after the circulation is completed, or the water pump device 340 is immediately controlled to be closed, and then the washing apparatus controls the three-way switch valve 261 to switch the conducting state to the inlet and the second outlet, and then restarts the water pump device 340 to drain water.

[0225] In the embodiment, the circulation operation and the drainage operation of the washing apparatus are driven by the same water pump device 340, and the conducting direction of the water path structure is controlled by the three-way switch valve 261, so as to realize the switching of the circulation operation and the drainage operation. The washing apparatus is also applicable to the control logic that the circulation washing water operation and the drainage operation are prohibited to be simultaneously performed, and the problem of the circulation noise does not occur.

[0226] Embodiment Nine

[0227] As shown in FIGS. 1 to 10, the embodiment is a further limitation of any of the above-mentioned embodiments, and the operation of the circulation washing water is set as a separate additional function, which can be set to be turned on or turned off by the user.

[0228] Specifically, in the embodiment, the washing apparatus has an openable / closable additional circulation function, and in the open state of the additional circulation function, the washing apparatus performs the circulation operation in the process of running the washing program, and drives the washing water in the tub 100 to flow along the circulation pipeline.

[0229] Further, in the embodiment, at least one washing program is set to have the additional circulation function turned on by default. Preferably, at least one washing program is set to have the additional circulation function turned on by default, and at least one washing program is set to have the additional circulation function turned off by default.

[0230] For example, the heavy-duty washing program, the strong washing program, and other washing programs with large washing strength of the washing apparatus have large friction strength on the washed articles in the washing process, and thus the additional circulation function is turned on by default, and the circulation operation is performed to filter the washing water in the running process, so as to reduce the situation that the lint is attached to the surface of the articles after the articles are cleaned. The delicate program has small friction strength on the articles, and thus the additional circulation function is turned off by default, and the circulation operation is not performed in the running process.

[0231] In the embodiment, the washing apparatus can receive the operation information of the user in the program setting stage after the washing apparatus is turned on, and then determine whether the additional circulation function is turned on in the current running.

[0232] As a specific embodiment, an additional cycle button is arranged on the operation panel of the washing apparatus, and in the program setting stage, the user triggers the additional cycle button to start or stop the additional cycle function.

[0233] More specifically, if the additional cycle function has been started, for example, the additional cycle function is started by default when the currently selected washing program is started, the user triggers the additional cycle button to stop the additional cycle function. Similarly, if the additional cycle function is stopped, for example, the additional cycle function is stopped by default when the currently selected washing program is started, the user triggers the additional cycle button to start the additional cycle function, and the washing program will perform the cycle operation at a preset stage.

[0234] In a further aspect of the embodiment, the user can also start the additional cycle function after the washing program is started.

[0235] As a specific embodiment, the washing apparatus runs the washing program in the state that the additional cycle function is stopped, and if a signal that the additional cycle button is triggered is received, the additional cycle function is started, and the cycle operation will be performed in the subsequent process of the washing program.

[0236] It can be understood that after the additional cycle function is started, the washing apparatus does not immediately perform the cycle operation, but performs the cycle operation on the washing water at a stage where the cycle operation can be performed.

[0237] Further, in the embodiment, the first instruction for triggering the cycle operation of the washing water is triggered by the start of the additional cycle function during the running of the washing program.

[0238] As a specific embodiment, the first instruction is the start instruction of the additional cycle function issued by the user through the operation panel.

[0239] As another specific embodiment, the washing apparatus triggers the first instruction after receiving the start instruction of the additional cycle function.

[0240] In the embodiment, as shown in FIG. 11, the washing apparatus further adopts the following control flow:

[0241] During the running of the washing program, the washing apparatus triggers the first instruction by starting the additional cycle function;

[0242] The first instruction is received, and it is determined whether the current is draining;

[0243] If the determination result is yes, the cycle washing water is started after the current draining operation is completed; if the determination result is no, the cycle washing water is allowed to be started.

[0244] With the specific structure of the washing equipment provided in Embodiment One as an example, in one specific scheme, when the washing equipment receives a signal that the additional cycle button is triggered during operation, the additional cycle function is started, and the main control module of the washing equipment receives the first instruction. At this time, the washing equipment first acquires the working state of the drain pump 310, and if it is in the running state, the circulating pump 320 is not allowed to be started, and the current drain operation is waited to end, the drain pump 310 is closed, and the circulating pump 320 is started again to perform the circulating operation after the washing equipment is filled with water again.

[0245] If the drain pump 310 is acquired to be in the closed state, the circulating pump 320 is allowed to be started. However, for different washing programs, the timing of the washing equipment to perform the circulating operation is not completely the same. Therefore, after the drain pump 310 is acquired to be in the closed state, the washing equipment further judges whether the current running stage is a stage that needs to be circulated, if yes, the circulating pump 320 is started, otherwise, the circulating pump 320 is started after the washing program runs to the corresponding stage.

[0246] In this embodiment, the washing equipment sets the operation of circulating the washing water as a separate additional function, which can be set to be started or closed by the user, and can more flexibly adapt to the actual needs of the user. For the case that the user starts the additional cycle function during the running of the washing program, the washing equipment judges whether the drain is being performed, to ensure that the execution process of the circulating operation is staggered with the drain operation, and no conflict is caused.

[0247] The above only describes the preferred embodiments of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiments, it is not intended to limit the present application, and any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, to make equivalent embodiments with equivalent changes, but as long as it does not depart from the technical solution of the present application, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application are still within the scope of the present application.
