The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] Clothes processing equipment is a common household appliance. With the improvement of living standards, fully automatic clothes processing equipment has entered every household, because clothes processing equipment is simple and convenient to use, and can provide a lot of convenience for our fast-paced life. When working, clothes processing equipment can handle the hair attached to clothes to complete the cleaning of clothes. The fallen hair will accumulate inside the clothes processing equipment. However, at the moment when clothes processing equipment has entered the intelligent era, clothes processing equipment still needs to manually clean the hair accumulated inside itself. This cleaning method will increase the workload and reduce consumers' good impression of the experience of clothes processing equipment. In addition, if consumers do not clean the hair accumulated inside the clothes processing equipment in time or forget to clean it, the hair will breed bacteria in a humid and shaded environment, and even rot, which will eventually have a harmful effect on consumers' health.

[0041] Reference below Figure 1-Figure 6 A self-cleaning assembly according to an embodiment of the present invention is described.

[0042] The self-cleaning component according to the present invention includes a shell, a filter device and a driving device. A accommodating chamber is formed in the shell, and a first interface, a second interface and a third interface are respectively connected to the accommodating chamber. The first interface is suitable for communicating with a water outlet of a clothing processing device, the second interface is suitable for communicating with a water return port of the clothing processing device, and the third interface is suitable for communicating with a sewage outlet; the filter device can be rotatably accommodated in the accommodating chamber, a filter chamber is formed in the filter device, and the filter chamber is connected to the second interface; the driving device is connected to the filter device, and the driving device is suitable for driving the filter device to rotate in the accommodating chamber.

[0043] According to the self-cleaning component of the present invention, a shell and a filter device are constructed, and a receiving chamber is defined inside the shell. The receiving chamber can accommodate the filter device so as to filter the sewage generated after the clothing processing device is working. Specifically, a first interface, a second interface and a third interface connected to the receiving chamber are provided on the shell, wherein the first interface can be connected to the drain outlet of the clothing processing device so as to guide the sewage generated by the clothing processing device to the self-cleaning component, the second interface can be connected to the return water outlet of the clothing processing device so as to guide the filtered water back to the clothing processing device for recycling, and the third interface can be connected to the sewage outlet so as to discharge the sewage in the shell when the self-cleaning component performs self-cleaning work. In addition, the filter device is rotatably arranged in the receiving chamber, and the operation of the driving device can drive the filter device to rotate rapidly. The filter device rotating at high speed can generate centrifugal force to make the hair debris on the filter device fall off, which is convenient for cleaning the filter device.

[0044] In some embodiments, the working process of the self-cleaning component can be roughly understood as follows: when it is necessary to filter the sewage, the first interface and the second interface are opened, and the third interface is closed. When the clothing processing device discharges the sewage after cleaning the clothes into the self-cleaning component through the pipeline, the filtering device can filter the sewage to remove impurities such as hair in the sewage. The filtered water can flow from the filter cavity through the second interface and then flow to the return water port of the clothing processing device for recycling. The setting of the second interface improves the utilization rate of water by the clothing processing device. At this time, the hair and other impurities filtered out by the filtering device will accumulate on the outer surface of the filtering device. When the self-cleaning component performs self-cleaning work, the first interface and the third interface are opened, the second interface is closed, and the driving device drives the filtering device to rotate. The water flowing out of the first interface can impact the filtering device. The hair on the filtering device falls off into the containing cavity under the action of centrifugal force and the impact of water flow. The sewage mixed with hair can flow to the sewage outlet through the second interface for discharge to complete the cleaning process of the self-cleaning component. The setting of the self-cleaning component recycles the water used in the cleaning process while achieving self-cleaning of hair debris accumulated in the clothing processing device, thereby improving the water utilization rate of the clothing processing device and avoiding the breeding of bacteria caused by the accumulation of hair debris. In addition, the self-cleaning process does not require manual operation, which improves the user experience.

[0045] According to one embodiment of the present invention, the shell includes a shell body and a cover body, a accommodating cavity and a first interface, a second interface and a third interface are formed in the shell body, and an installation port is formed on the shell body; the cover body is detachably arranged at the installation port, a filtering device is rotatably arranged on a side of the cover body facing the accommodating cavity, and a driving device is arranged on a side of the cover body away from the accommodating cavity.

[0046] Since the cleaning process of the self-cleaning component is carried out in the shell, the structure of the shell will affect the cleaning effect of the self-cleaning component. Specifically, the shell is provided with a shell body and a cover body, and a housing cavity is formed in the shell body, and a first interface, a second interface and a third interface connected to the housing cavity are formed. Among them, the first interface can guide the water delivered by the clothing processing device into the housing cavity; the second interface can guide the water filtered by the filter device to the return water port of the clothing processing device; the third interface can guide the water in the housing cavity to the sewage outlet so that the self-cleaning component can discharge sewage. The housing cavity, the first interface, the second interface and the third interface are the basic structures for the flow of water in the self-cleaning component. The housing cavity, the first interface, the second interface and the third interface are processed on the shell body to facilitate the assembly of other structures of the self-cleaning component. At the same time, an installation port is also provided on the shell body, and the installation port is connected to the housing cavity. The setting of the installation port facilitates the self-cleaning component to assemble the filter device. During assembly, the filter device can be directly assembled into the housing cavity through the installation port, thereby improving the assembly efficiency.

[0047] In addition, the cover body is detachably arranged on the installation port, and can seal the accommodating chamber after the filter device is assembled into the accommodating chamber to prevent the filter device from falling off from the accommodating chamber, thereby improving the stability of the internal structure of the self-cleaning component after assembly. At the same time, the filter device is rotatably arranged on the side of the cover body facing the accommodating chamber. After the filter device is connected to the cover body, the cover body can serve as a support when the filter device rotates, thereby improving the stability of the filter device during rotation. A driving device is arranged on the side of the cover body away from the accommodating chamber, and the driving device can selectively drive the filter device to rotate. For example, when the self-cleaning component is in the self-cleaning process, the driving device can drive the filter device to rotate rapidly. At this time, the hair on the surface of the filter device will fall into the accommodating chamber under the action of centrifugal force and the impact of water, and the hair mixed with water in the accommodating chamber will flow to the sewage outlet through the third interface and be discharged. The setting of the driving device improves the self-cleaning effect of the self-cleaning component.

[0048] According to one embodiment of the present invention, the driving device includes a motor and a base, the base is fixedly connected to the side of the cover body away from the accommodating chamber, and the end of the base away from the cover body is provided with a motor mounting position, and the motor mounting position is suitable for fixing the motor. Since the driving device is a structure for driving the filter device to rotate, the structure of the driving device will affect the rotation of the filter device. The driving device is provided with a motor and a base, and the base is a structure for fixing the motor. Specifically, the base is fixedly connected to the side of the cover body away from the accommodating chamber, and the connection method can be welding or clamping, etc. The connection between the base and the cover body facilitates the fixation of the base itself. When the cover body is assembled to the mounting port, the base can be stably connected to the shell body through the cover body. The base is also provided with a motor mounting position at one end away from the accommodating chamber, and the motor mounting position can be used to fix the motor. During assembly, the motor is fixed to the base through the motor mounting position, and the base is fixedly connected to the cover body. At this time, the filter device can be assembled on the side of the cover body close to the accommodating chamber; after assembly, the driving device, the cover body and the filter device are integrated and assembled to the shell body as a whole, which improves the stability of the driving device and the filter device after assembly.

[0049] According to one embodiment of the present invention, the base is formed with an installation cavity that is open away from the cover body, and the installation cavity is configured as a motor installation position, and at least a portion of the motor is suitable for being accommodated in the installation cavity. Since the motor installation position on the base can be used to fix the motor, the structure of the motor installation position will affect the assembly of the motor. The base is formed with an installation cavity that is open away from the cover body, and the installation cavity is configured as the motor installation position in the above embodiment. During assembly, at least a portion of the motor can be accommodated in the installation cavity, and the structure of the installation cavity improves the stability of the motor during assembly.

[0050] According to one embodiment of the present invention, the inner peripheral wall of the installation cavity forms a limiting protrusion, and the limiting protrusion abuts against the outer periphery of the motor. Since the motor can be assembled in the installation cavity, the structure of the installation cavity will affect the stability of the motor during assembly. Specifically, the base is provided with a limiting protrusion on the inner peripheral wall of the installation cavity, and when the motor is assembled into the installation cavity, the limiting protrusion can abut against the outer surface of the motor to prevent the motor from falling out of the installation cavity.

[0051] In some embodiments, the limiting protrusion can be constructed of rubber material. The limiting protrusion made of rubber material can increase the friction between the limiting protrusion and the surface of the motor, further improving the stability of the motor during assembly. At the same time, the limiting protrusion made of rubber material will not damage the motor when the motor is interference-fitted, thereby improving the safety of the motor.

[0052] According to one embodiment of the present invention, an oil seal groove is formed on the side of the bottom wall of the cover body facing the motor, and the driving device also includes an oil seal, and the oil seal sleeve is arranged on the outer periphery of the motor shaft of the motor and is accommodated in the oil seal groove. Since the motor is a component that transmits torque to the filter device to drive the filter device to rotate and a cover body is arranged between the motor and the filter device, the structure of the cover body will affect the working process of the motor. Specifically, a motor shaft is arranged on the motor, and the motor shaft is connected to the filter device. When the motor is working, the motor shaft rotates and transmits torque to the filter device to drive the filter device to rotate. The bottom wall of the cover body is provided with an oil seal groove on the side facing the motor. During assembly, the oil seal sleeve is arranged on the outer periphery of the motor shaft and then assembled into the oil seal groove. The oil seal can prevent the lubricating oil on the motor shaft from entering the installation cavity through the gap between the cover body and the motor shaft, thereby avoiding the leakage of the lubricating oil. The structure of the oil seal groove improves the stability of the oil seal during assembly.

[0053] According to one embodiment of the present invention, the self-cleaning component also includes an adapter, which is respectively connected to the motor shaft and the filter device. Since the torque generated by the motor is transmitted to the filter device through the motor shaft, the connection method between the motor shaft and the filter device will affect the transmission of torque. The self-cleaning component is provided with an adapter between the motor shaft and the filter device, and the adapter is respectively connected to the motor shaft and the filter device. When the motor is working, the torque generated by the motor is transmitted to the adapter through the motor shaft, and the adapter can transmit the received torque to the filter device to drive the filter device to rotate in the accommodating chamber. The provision of the adapter realizes the transmission of torque between the motor shaft and the filter device, ensuring that the motor can normally drive the filter device to rotate.

[0054] According to one embodiment of the present invention, an extension portion extending toward the filter device is formed on a side of the bottom wall of the cover body away from the motor, and a first groove is formed on the filter device, and at least a portion of the extension portion can be selectively extended into the first groove. Since the filter device is arranged on a side of the cover body close to the accommodating chamber, the structure of the cover body will affect the assembly of the filter device. The self-cleaning assembly is provided with a first groove on the filter device, and at the same time, an extension portion is formed on the bottom wall of the cover body on a side away from the motor. During assembly, at least a portion of the extension portion can be accommodated in the first groove of the cover body, which can be understood as: the filter device can rotate on the extension portion, and the structure of the extension portion improves the stability of the filter device during rotation. It is worth noting that the setting position of the extension portion and the oil seal groove in the above embodiment are respectively located on both sides of the bottom wall of the cover body.

[0055] According to one embodiment of the present invention, the extension defines a second groove open toward one side of the accommodating cavity, the bottom wall of the first groove is provided with a third groove, and the second groove and the third groove are opposite; the adapter is respectively received in the second groove and the third groove. Since the adapter can transmit the torque of the motor shaft to the filter device, the setting position of the adapter will affect the transmission of the torque. The filter device is provided with a third groove recessed toward the inside of the accommodating cavity on the bottom wall of the first groove, and at the same time, the extension and the bottom wall of the cover body define the second groove. When the cover body and the filter device are assembled, the second groove and the third groove are opposite. At this time, one end of the adapter can be received in the second groove, and the other end of the adapter can be received in the third groove. It can be understood that the end face of the second groove can be fitted with the end face of the third groove. When the filter device is matched with the cover body, the extension extends into the first groove. At this time, the end face of the second groove and the end face of the third groove are fitted with each other, so that the second groove and the third groove jointly define a cavity, and the adapter can be received in the cavity defined by the cooperation of the second groove and the third groove. The structure of the second groove and the third groove provides space for the assembly of the adapter, improves the stability of the adapter after assembly, and facilitates the transmission of torque by the adapter.

[0056] According to one embodiment of the present invention, the adapter is configured as a sleeve, the inner circumferential wall of the sleeve abuts against the motor shaft, and the outer circumferential wall of the sleeve abuts against the inner wall of the third groove. Since the adapter is a structure for transmitting torque, the configuration of the adapter will affect the rotation of the filter device. The self-cleaning assembly configures the adapter as a sleeve, and the sleeve is provided with an inner surface and an outer surface. During assembly, the open end of the sleeve is sleeved on the motor shaft, and the other end of the sleeve is accommodated in the third groove. At this time, at least part of the inner surface of the sleeve abuts against the outer circumferential surface of the motor shaft, and at least part of the outer surface of the sleeve can abut against the inner circumferential wall of the third groove. It can also be understood that: the motor shaft extends into the sleeve through the open end of the sleeve and has an interference fit with the sleeve, and the end of the sleeve away from the motor shaft extends into the third groove and has an interference fit with the third groove. During rotation, the motor drives the motor shaft to rotate, and the motor shaft drives the sleeve and then drives the entire filter device to rotate. The configuration of the sleeve realizes the transmission of torque between the motor shaft and the filter device, and also improves the stability of the connection between the motor shaft and the filter device.

[0057] It is worth noting that the diameter of the second groove in the above embodiment is slightly larger than the diameter of the third groove. Since the end of the sleeve away from the motor shaft is interference fit with the third groove, the end of the sleeve close to the motor shaft cannot abut against the inner wall of the second groove when accommodated in the second groove. The sleeve can rotate in the second groove to avoid the cover body obstructing the transmission of torque by the adapter.

[0058] According to one embodiment of the present invention, the filter device includes a bracket and a filter screen, one end of the bracket is connected to the sleeve, and the other end of the bracket is provided with a filter outlet connected to the second interface; the filter screen is provided on the outer circumference or inner circumference of the bracket to define a filter cavity. Since the filter device is a structure used for cleaning in the self-cleaning assembly, the structure of the filter device will affect the cleaning effect of the self-cleaning assembly. The filter device is provided with a bracket and a filter screen, and the bracket can be understood as a supporting structure of the filter device as a whole. The bracket is accommodated in the accommodating cavity and one end of the bracket is fixedly connected to the sleeve. When the filter device is matched with the cover body, the bracket and the cover body can rotate relative to each other. When the motor is working, the bracket itself receives the torque transmitted by the sleeve and rotates and can drive the entire filter device to rotate; when the motor is not started, the water flow sprayed from the first interface impacts the filter screen and can drive the bracket to rotate. At this time, the sleeve is driven by the bracket to drive the motor shaft to idle. The bracket, as the prime mover of the filter device, can make the filter device rotate in the accommodating cavity, ensuring that the filter device can work normally.

[0059] The filter can be arranged on the outer circumference or inner circumference of the bracket. The filter is mainly used to filter sewage and define a filter cavity in the accommodating cavity so as to separate the sewage and the filtered water. At the same time, the bracket is also provided with a filter outlet connected to the second connection port at the end. When the self-cleaning component filters the sewage, the sewage transported by the clothing treatment equipment is filtered by the filter device and is in the filter cavity. The water in the filter cavity can flow back to the return water port of the clothing treatment equipment through the filter outlet and the second connection port for recycling. It is worth noting that the filter can be arranged on the inner circumference of the bracket or on the outer circumference of the bracket. The scheme of setting the filter on the outer circumference of the bracket is convenient for filter assembly but not for filter fixing. The scheme of setting the filter on the inner circumference of the bracket is convenient for filter fixing but not for filter assembly. The specific setting scheme can be selected according to the actual situation during processing and assembly.

[0060] According to one embodiment of the present invention, the first interface and the third interface extend radially along the rotating shaft of the bracket, and the second interface and the mounting port extend axially along the rotating shaft of the bracket. Since the water in the self-cleaning assembly needs to flow through the first interface, the second interface and the third interface when the self-cleaning assembly is working, the structure of the first interface, the second interface and the third interface will affect the cleaning process of the self-cleaning assembly. The first interface extends radially along the rotating shaft of the bracket. When the sewage generated by the clothing processing equipment enters the accommodating chamber, it can flow radially to the filter device under the guidance of the first interface. The radially arranged first interface can make the sewage flow directly to the outer peripheral surface of the filter device. It can also be understood that the sewage at this time can directly impact the filter screen, thereby improving the filtering efficiency of the filter device. The second interface extends axially along the rotating shaft of the bracket. When the filter device is assembled in the accommodating chamber, the second interface can be directly opposite to and connected to the filter outlet. The position setting scheme of the second interface can make the water in the filter cavity quickly flow back to the return water outlet of the clothing processing equipment through the second interface. The third interface can extend in the radial direction of the rotating shaft of the bracket. The setting scheme of the third interface makes the third interface and the first interface located on both sides of the filter device respectively. When the self-cleaning component cleans the filter device, the water for flushing the filter screen can directly flow into the third interface, thereby improving the sewage discharge efficiency of the self-cleaning component. In addition, the mounting port on the shell can extend in the axial direction of the rotating shaft of the bracket. The mounting port extending in the axial direction of the rotating shaft of the bracket facilitates the assembly of the filter device. Specifically, when the filter device is assembled into the accommodating cavity through the mounting port, the bracket can be orthogonal to the extension direction of the first interface without additional position adjustment, thereby reducing the difficulty of assembling the filter device.

[0061] According to one embodiment of the present invention, the self-cleaning assembly further includes a first pump housing and a second pump housing, wherein the first pump housing is disposed on the housing body and a first cavity is formed in the first pump housing, the first cavity is communicated with the second interface, and a first pump outlet communicated with the water return port is radially disposed in the first pump housing; the second pump housing is disposed on the housing body and a second cavity is formed in the second pump housing, the second cavity is communicated with the third interface, and a second pump outlet communicated with the sewage outlet is radially disposed in the second pump housing. Since the water flow of the self-cleaning assembly needs to pass through the connecting pipeline between the housing and the clothing processing device, the structure of the housing will affect the connection of the pipeline.

[0062] Specifically, the self-cleaning component is also provided with two pump shells on the housing, namely, a first pump shell and a second pump shell, wherein the first pump shell is provided on the housing body and a first cavity is formed in the first pump shell, the first cavity can be communicated with the second interface so that the water in the filter cavity can enter the first cavity through the second interface, and a first pump outlet communicated with the return port can also be provided in the radial direction of the first pump shell. When the self-cleaning component filters and cleans the sewage generated by the clothing processing device, the first interface and the second interface are opened, and the third interface is closed, and the sewage generated by the clothing processing device enters the accommodating cavity through the first interface, and the sewage in the accommodating cavity can flow into the filter cavity after being filtered by the filter device, and the water in the filter cavity can flow into the first cavity through the second interface, and the water entering the first cavity flows back to the return port of the clothing processing device under the guidance of the first pump outlet for recycling. The setting of the first pump shell enables the water in the filter cavity to be separated from the sewage in the accommodating cavity in the flow route, thereby avoiding secondary pollution. At the same time, the setting of the first pump outlet facilitates the communication between the return port of the clothing processing device and the second interface, and also facilitates the arrangement of the pipeline for conveying water. In addition, a first driving member can be arranged in the first pump housing, and the first driving member can be used to drive the water in the filter chamber to flow toward the return water outlet of the clothing processing equipment, so as to avoid the filtered water from accumulating in the filter chamber, thereby allowing the sewage in the receiving chamber to enter the filter chamber faster, thereby improving the water purification capacity of the self-cleaning component.

[0063] The second pump housing can also be arranged on the housing body, similar to the arrangement of the first pump housing, the second pump housing can define a second cavity inside, the second cavity can be connected to the third interface so that the sewage in the accommodating cavity can enter the second cavity through the third interface, and a second pump outlet connected to the sewage outlet can be arranged in the radial direction of the second pump housing. When the self-cleaning component cleans the filter screen, the first interface and the third interface are opened, and the second interface is closed, and the clothing processing device can spray water toward the accommodating cavity through the first interface, and the water sprayed from the first interface can clean the impurities such as hair scraps on the surface of the filter screen, and the hair scraps falling from the filter screen are mixed with the water sprayed from the first interface and flow to the second cavity together, and the mixture of water and hair scraps after entering the second cavity can flow to the sewage outlet through the second pump outlet. The design of the second pump housing enables the hair scraps on the filter device to be discharged in time after falling off, avoiding the accumulation of hair scraps in the accommodating cavity and affecting the filtering effect of the filter device. Similarly, a second driving member can also be arranged in the second pump housing to drive the water in the accommodating cavity to flow quickly to the sewage outlet, thereby improving the self-cleaning ability of the self-cleaning component.

[0064] In some embodiments, the base may be provided with a lug, and during assembly, after the motor, base, cover and filter device are assembled into one, the cover can be rotated and tightened into the installation opening through the lug. The provision of the lug can improve the assembly efficiency of the self-cleaning assembly.

[0065] The clothes treating apparatus according to the present invention will be briefly described below.

[0066] The clothing treatment device according to the present invention includes the self-cleaning component in the above-mentioned embodiment. Since the clothing treatment device according to the present invention is provided with the self-cleaning component in the above-mentioned embodiment, during the use of the clothing treatment device, the sewage generated by the clothing treatment device can flow into the self-cleaning component and flow back to the water return port of the clothing treatment device again after being filtered by the filter device for secondary use, thereby improving the utilization rate of water by the clothing treatment device. In addition, when the self-cleaning component performs self-cleaning, the driving device can drive the filter device to rotate rapidly in the accommodating chamber, and the clothing treatment device can spray water toward the filter device through the first interface. The hair debris on the filter device falls off into the accommodating chamber under the action of centrifugal force and the impact force of water. The hair debris that falls off can flow to the sewage outlet through the third interface together with the sewage generated after cleaning and be discharged, thereby improving the self-cleaning ability of the self-cleaning component and avoiding secondary contamination of the clothing treatment device. Moreover, the self-cleaning process does not require manual operation, thereby improving the user experience.

[0067] In summary, the self-cleaning component defines a housing cavity by setting a shell, and a filter device is assembled in the housing cavity to filter the sewage generated by the clothing processing device. At the same time, a driving device is also arranged outside the shell, and the driving device can drive the filter device to rotate quickly so that the water flow cleans the filter device. Specifically, the shell is constructed with a shell body and a cover body, and a housing cavity with a mounting port is defined in the shell body, and the filter device can be directly assembled into the housing cavity through the mounting port, thereby improving the efficiency of the assembly of the filter device. The cover body can seal the mounting port to prevent the water in the housing cavity from flowing out of the mounting port. At the same time, an extension portion is provided on one side of the cover body facing the housing cavity, and the extension portion can cooperate with the first groove on the bracket of the filter device to realize a rotatable connection between the filter device and the cover body. The second groove defined in the extension portion and the third groove defined in the bracket can fit each other to form a cavity of the housing cavity adapter, thereby improving the assembly stability of the adapter. A base can be provided on the side of the cover body away from the housing cavity, and a mounting cavity can be processed at one end of the base away from the cover body to accommodate the motor to improve the assembly stability of the motor. The filter device defines a filter cavity through the cooperation of the bracket and the filter screen. At the same time, a filter outlet is also provided on the bracket. The water filtered by the filter screen can flow from the filter cavity through the filter outlet and then flow into the first cavity defined by the first pump housing. The water in the first cavity flows back to the return water port of the clothing processing device through the first pump outlet under the drive of the first driving member; and the water for cleaning the filter screen in the accommodating cavity can flow into the second cavity defined by the second pump housing through the third interface. The water in the second cavity can flow to the sewage outlet through the second pump outlet under the drive of the second driving member and be discharged. The setting of the self-cleaning component can not only purify the sewage generated by the clothing processing equipment and recycle the purified water, but also drive the filter device to rotate quickly through the driving device to improve the water's cleaning ability on the filter screen and thus realize the self-cleaning process, avoiding secondary contamination of the clothing processing equipment. At the same time, no manual operation is required during the whole process, which improves the user experience.
