[0036] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0037] Clothes processing equipment is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. It is divided into two categories according to its rated washing capacity: household and collective. Household clothes processing equipment is mainly composed of a box, a washing and dehydrating barrel (some washing and dehydrating barrels are separate), a transmission and control system, etc., and some are also equipped with a heating device.

[0038] According to the washing type, clothes processing equipment can be mainly divided into pulsator type and drum type.

[0039] The pulsator-type clothing processing equipment has a disc pulsator at the bottom of the barrel with protruding ribs on it. The pulsator is driven by an electric motor to rotate. Driven by the pulsator, the water flow in the barrel forms a vortex that sometimes rotates right and sometimes rotates left, driving the clothes to rotate and tumble. The clothes are constantly turned up and down and left and right, so that the clothes and the barrel wall are gently rubbed in the water, so that the dirt on the clothes can be removed.

[0040] The drum-type clothing processing equipment imitates the principle of a hammer hitting clothing, and uses the mechanical work of the motor to rotate the drum. The clothing is continuously lifted up and dropped down in the drum, and then lifted up and dropped again, doing repeated movements. The combined action of detergent and water makes the clothing clean.

[0041] A movable friction component 20 that can move relative to the washing tub 10 is added to the clothing processing device 100 provided in the present application. When the clothing falls, tumbles or rotates, it will rub against the movable friction component 20, which can be understood as an action similar to rubbing clothes, so as to achieve the purpose of cleaning and improve the cleaning ratio of the clothing processing device 100.

[0042] Reference below Figure 1-Figure 4 The laundry processing device 100 in the embodiment of the present application is described. The laundry processing device 100 in the embodiment of the present application takes a household laundry processing device as an example, and can be implemented in a pulsator type laundry processing device and a drum type laundry processing device. It should be noted that the pulsator type laundry processing device and the drum type laundry processing device are only a specific embodiment among many embodiments, and cannot be used as a specific limitation of the present application.

[0043] According to one embodiment of the present application, the laundry processing device 100 mainly includes: a washing tub 10 and a moving friction assembly 20 .

[0044] The washing tub 10 is disposed in the housing of the laundry processing device 100 and is used for washing laundry. There is a washing space 101 in the washing tub 10. Laundry can be placed in the washing space 101 and filled with washing water. When the washing tub 10 rotates or the pulsator 30 agitates, the laundry in the washing space 101 is cleaned.

[0045] The movable friction component 20 is installed on the inner wall of the washing tub 10 and can be in contact with the clothes. During the operation of the clothing processing device 100, the movable friction component 20 rubs against the clothes. The movable friction component 20 can be understood as a structure similar to a washboard. The friction between the movable friction component 20 and the clothes is equivalent to the process of washing clothes. Adding the movable friction component 20 can add an extra washing dimension on the basis of the current clothing processing device 100, thereby achieving the purpose of improving the washing ratio.

[0046] During the contact between the movable friction component 20 and the clothes, the movable friction component 20 may partially move relative to the washing tub 10 or may completely move relative to the washing tub 10 .

[0047] The washing tub 10 has an open end 11 and a closed end 12 in the axial direction, the open end 11 is provided with an open port, and in the pulsator 30 type laundry treating apparatus 100 , the closed end 12 is provided with a pulsator 30 .

[0048] In a specific embodiment, in the pulsator 30 type clothing processing device 100, the open mouth of the washing tub 10 is opened to the upper side, and the pulsator 30 is located at the bottom of the washing tub 10 and directly opposite to the open mouth. That is to say, the washing tub 10 is placed vertically. After the clothes are put into the open mouth on the upper side, the clothes fall on the pulsator 30 at the bottom of the washing tub 10 under the action of gravity. During operation, the pulsator 30 will rotate intermittently in the forward and reverse directions, while the washing tub 10 is stationary and does not rotate. The clothes tumble and rotate up and down during the stirring process of the pulsator 30. During the tumbling and rotating of the clothes, the clothes and the clothes and the tub wall can be gently rubbed in the water, so that the dirt on the clothes can be removed. A movable friction component 20 is added to the inner wall surface of the washing tub 10. The movable friction component 20 can be partially or completely moved relative to the washing tub 10. Specifically, it can move up and down along the axial direction of the washing tub 10, which is equivalent to adding a washing dimension. When the clothes tumble up and down, the clothes rub against the movable friction component 20, which further enhances the cleaning power of the impeller 30 type clothing processing device 100 and improves the washing ratio.

[0049] In another specific embodiment, in the drum-type laundry processing device 100, the open mouth of the washing tub 10 is open to the front side, and the washing tub 10 is placed horizontally. After the laundry is put into the open mouth on the front side, the laundry is directly attached to the inner wall surface of the washing tub 10. During operation, the drum rotates in one direction, and the laundry is brought to a high place by the inner wall surface of the washing tub 10 under the action of friction. When the friction force is less than gravity, the laundry falls to the lowest inner wall surface. The laundry is continuously lifted and dropped in the washing tub 10, and then lifted and dropped again, performing repeated movements, and the laundry is cleaned in a form similar to knocking. The moving friction component 20 on the inner wall surface of the washing tub 10 will rotate with the washing tub 10 and provide friction on the inner wall surface where the moving friction component 20 is set. The friction cleaning between the laundry and the moving friction component 20, plus the cleaning form similar to knocking, further enhances the cleaning strength of the drum-type laundry processing device 100 and improves the washing ratio.

[0050] According to the clothing processing device 100 of the present application, by adding a mobile friction component 20, during the operation of the clothing processing device 100, the mobile friction component 20 can move relative to the washing tub 10, and the clothes can be rubbed and cleaned on the mobile friction component 20, which is equivalent to adding a cleaning dimension, which is beneficial to increasing the cleaning ratio of the clothes and enhancing the washing effect of the clothing processing device 100.

[0051] According to one embodiment of the present application, the moving friction assembly 20 includes: a moving member 21 and a mounting seat 23. The moving member 21 can move relative to the washing tub 10 during the washing process, and the mounting seat 23 is fixed to the inner wall surface of the washing tub 10. It can be understood that the moving member 21 is installed on the mounting seat 23, and the moving member 21 can move on the mounting seat 23. During the washing process, the moving member 21 can move relative to the mounting seat 23, and the moving member 21 rubs against the clothes in the washing tub 10, thereby washing the clothes.

[0052] In one embodiment, the mounting seat 23 is provided with a mounting space, the moving member 21 is provided in the mounting space, and a sidewall surface of the mounting seat 23 close to the washing space 101 is provided with a avoidance opening provided toward the washing space 101, the avoidance opening is communicated with the mounting space, the moving member 21 moves in the mounting space, and a friction portion 24 is provided on the moving member 21 toward the washing space 101, and the friction portion 24 can increase the contact area with the clothes, and rub when the clothes tumble and rotate. In other words, the avoidance opening is directly opposite to the friction portion 24, and the friction portion 24 on the moving member 21 is often exposed, and the clothes can contact and rub with the friction portion 24 to wash the clothes.

[0053] According to some embodiments of the present application, the size of the friction part 24 in the moving direction is larger than the size of the avoidance opening in the moving direction of the friction part 24. Therefore, during the movement of the friction part 24, at least part of the friction part 24 is directly opposite to the avoidance opening, and no matter how the moving member 21 moves, the avoidance opening can always be shielded by the friction part 24, and the area where the avoidance opening is located always has the friction part 24 to rub against the clothes, thereby ensuring the contact area between the friction part 24 and the clothes, making it easy to clean the clothes.

[0054] According to an embodiment of the present application, the friction portion 24 can be constructed as a plurality of friction strips 241 arranged at intervals, such as Figure 2 As shown, the friction strips 241 are convexly arranged and arranged in sequence along the axial direction of the washing tub 10. The overall shape is similar to a washboard. The friction strips 241 can increase the friction between the clothes and the friction part 24, which is beneficial to the washing of the clothes.

[0055] The moving member 21 can be linked with the pulsator 30. During the rotation of the pulsator 30, the pulsator track 40 rotates with the pulsator 30, and the moving member can be linked with the pulsator 30. The pulsator 30 is rotatable relative to the washing tub 10. During the washing process, under the drive of the pulsator 30, the moving member 21 moves relative to the washing tub 10.

[0056] According to one embodiment of the present application, during the washing process, the moving member 21 moves along the circumferential direction of the washing tub 10. Specifically, a moving track can be opened on the inner wall of the washing tub 10 for the moving member 21 to move circumferentially. Of course, a mounting support can also be set on the inner wall of the washing tub 10 for the moving member 21 to move circumferentially. During the circumferential movement of the moving member 21, it can rub against the clothes, thereby further enhancing the ability of the clothing processing device 100 to clean the clothes.

[0057] The moving member 21 can be driven by an additional driving member, such as a driving motor. Under the driving action of the driving motor, the moving member 21 can move relative to the washing tub 10 to rub against the clothes in the washing tub 10.

[0058] In one embodiment, a pulsator track 40 is provided on the pulsator 30 , one end of the moving member 21 is inside the pulsator track 40 and contacts and stops with the inner surface 41 of the pulsator track, and the moving member 21 can move along the circumference of the washing tub 10 under the rotation drive of the pulsator 30 .

[0059] Since the inner surface 41 of the pulsator track is a wavy convex surface, the distance between the inner surface 41 of the pulsator track and the open opening of the washing tub 10 is different. Figure 4 As shown, when the moving member 21 stops against the part of the inner surface of the impeller track 40 close to the opening, the moving member 21 is lifted and moved upward; when the moving member 21 stops against the part of the inner surface of the impeller track 40 away from the opening, the moving member 21 can move downward under the action of gravity. The moving member 21 can move in the direction close to or away from the opening during the washing process. That is to say, when the moving member 21 slides on the impeller track 40, it can move back and forth in the up and down directions according to the distance between the inner surface 41 of the impeller track and the opening, thereby increasing the friction in the up and down dimensions and improving the washing ratio.

[0060] The moving member 21 on the moving friction assembly 20 can move along the circumferential direction of the washing tub 10, and the moving direction of the moving member 21 can be the same as or opposite to the rotation direction of the pulsator 30. That is, when the moving direction of the moving member 21 is opposite to the rotation direction of the pulsator 30, the pulsator 30 rotates clockwise and the moving member 21 rotates counterclockwise, or the pulsator 30 rotates counterclockwise and the moving member 21 rotates clockwise; when the moving direction of the moving member 21 is the same as the rotation direction of the pulsator 30, the pulsator 30 rotates clockwise and the moving member 21 also rotates clockwise, or when the pulsator 30 rotates counterclockwise, the moving member 21 also rotates counterclockwise.

[0061] It should be noted that the clothes rotate together with the impeller 30 and the water flow in the washing tub 10, and it can be considered that the rotation direction of the clothes is the same as the rotation direction of the impeller 30, but due to the friction between the clothes and the inner wall of the washing tub 10, the rotation speed of the clothes must be lower than the rotation speed of the impeller 30. Therefore, as long as the rotation speeds of the moving part 21 and the clothes are different, even if they rotate counterclockwise or clockwise, the clothes and the moving part 21 must have relative motion, and then the clothes can rub against the moving part 21, thereby improving the washing ratio of the clothes processing device 100. Preferably, when the rotation direction of the impeller 30 is counterclockwise, the moving direction of the moving part 21 is clockwise; when the rotation direction of the impeller 30 is clockwise, the moving direction of the moving part 21 is counterclockwise.

[0062] According to one embodiment of the present application, the moving friction assembly 20 further includes: an elastic member 22, such as Figure 1 As shown, the elastic member 22 is arranged in the installation space. Specifically, the elastic member 22 is arranged on the upper side of the moving member 21 . One end of the elastic member 22 is connected to the mounting seat 23 , and the other end is connected to the moving member 21 .

[0063] In multiple embodiments, the elastic member 22 can be in different states. For example, the elastic member 22 can be in a compressed state all the time, the elastic member 22 can be in a stretched state all the time, or the elastic member 22 can sometimes be in a compressed state and sometimes be in a stretched state.

[0064] In a specific embodiment, no matter whether the moving part 21 is close to or far from the opening due to the action of the inner surface 41 of the impeller track during the washing process, the elastic part 22 is always in a compressed state. When the moving part 21 is closer to the opening, the elastic part 22 is compressed to a greater extent, and when the moving part 21 is farther from the opening, the elastic part 22 is compressed to a lesser extent.

[0065] In another specific embodiment, no matter whether the moving part 21 is close to or far from the opening due to the action of the inner surface 41 of the impeller track during the washing process, the elastic part 22 is always in a stretched state. When the moving part 21 is closer to the opening, the elastic part 22 is stretched more, and when the moving part 21 is farther from the opening, the elastic part 22 is stretched less.

[0066] The above two situations are both likely to implement the solution of the present application. When the elastic member 22 is always in a compressed state, the movable member 21 needs to overcome the downward pressing force of the elastic member 22 to move upward, which will increase the pressure on the impeller track 40. The inner surface 41 of the impeller track supports the movable member 21 to lift up, but in the process of the movable member 21 moving downward, there is not only the effect of the movable member 21's own gravity but also the effect of the elastic member 22's restoring force. Under the dual effect, the movable member 21 is easier to return to its initial position; when the elastic member 22 is always in a stretched state, the movable member 21 is pressed against the inner surface of the impeller track under the effect of the pulling force, and the movable member 21 needs to overcome the downward pulling force of the elastic member 22 to move upward, which will increase the pressure on the impeller track 40. The inner surface 41 of the impeller track supports the movable member 21 to lift up, but in the process of the movable member 21 moving downward, there is not only the effect of the movable member 21's own gravity but also the pulling force of the elastic member 22. Under the dual effect, the movable member 21 is easier to return to its initial position.

[0067] A roller 50 is provided at one end of the moving part 21. The roller 50 can be stuck in the impeller track 40. The roller 50 contacts the inner surface 41 of the impeller track. This can ensure that one end of the moving part 21 always stops at the inner surface 41 of the impeller track and can move up and down with the changes of the inner surface 41 of the impeller track.

[0068] Of course, the roller 50 can also rotate on the inner surface 41 of the impeller track to change the sliding friction into rolling friction, thereby reducing the friction between the moving part 21 and the inner surface 41 of the impeller track.

[0069] In another specific embodiment, when the moving part 21 is closer to the opening during the washing process, the elastic part 22 is in a compressed state, and when the moving part 21 is farther away from the opening during the washing process, the elastic part 22 is in a stretched state. This embodiment is the most ideal state of the elastic part 22. The inner surface 41 of the impeller track supports the moving part 21 and lifts it upward. At this time, the elastic part 22 is in a compressed state. When the moving part 21 moves downward, the spring restoring force and the gravity of the moving part 21 work together to return the moving part 21 to its initial position.

[0070] According to one embodiment of the present application, there is a friction reducing portion between the moving member 21 and the mounting seat 23, such as Figure 3As shown, there is a slider 211 on the movable member 21, and the slider 211 is arranged in a convex shape in the length direction of the movable member 21. There is a slide groove 2301 corresponding to the slider 211 in the installation space, and the slide groove 2301 is opened in the length direction of the mounting seat 23, and the slider 211 can slide in the slide groove 2301, that is, the slider 211 can slide along the slide groove 2301 in the up and down directions to approach or move away from the open mouth, and the friction reducing part is constructed as a plurality of arc protrusions 60 on the slider 211, and the plurality of arc protrusions 60 stop against the inner wall surface of the slide groove 2301. It can be understood that after designing a plurality of arc protrusions 60, the slide groove 2301 and the slider 211 are changed from surface-to-surface contact to point-to-surface contact, which can reduce the friction between the slider 211 and the slide groove 2301.

[0071] In the present application, there may be multiple movable friction components 20, and the multiple movable friction components 20 are arranged circumferentially on the inner wall surface of the washing tub 10. The more movable friction components 20 there are, the higher the cleaning degree of the clothes.

[0072] According to one embodiment of the present application, the clothing processing device 100 also includes a fixed friction component, which is constructed as a plurality of protrusions on the inner wall surface of the washing barrel 10 facing the washing space 101. When the clothes fall, tumble or rotate, they will rub against the fixed friction component, which can be understood as an action similar to rubbing clothes, so as to achieve the purpose of cleaning and improve the cleaning ratio of the clothing processing device 100.

[0073] Refer to the following Figure 1-Figure 4 The laundry treatment device 100 according to the embodiment of the present application is described in detail. It is worth noting that the following description is only an exemplary description and cannot be used as a specific limitation of the present application.

[0074] The laundry treatment device 100 mainly includes a washing tub 10 and a moving friction assembly 20 .

[0075] The washing tub 10 is disposed in the housing of the laundry processing device 100 and is used for washing laundry. There is a washing space 101 in the washing tub 10. Laundry can be placed in the washing space 101 and filled with washing water. When the washing tub 10 rotates or the pulsator 30 agitates, the laundry in the washing space 101 is cleaned.

[0076] The movable friction component 20 is installed on the inner wall of the washing tub 10 and can be in contact with the clothes. During the operation of the clothing processing device 100, the movable friction component 20 rubs against the clothes. The movable friction component 20 can be understood as a structure similar to a washboard. The friction between the movable friction component 20 and the clothes is equivalent to the process of washing clothes. Adding the movable friction component 20 can add an extra washing dimension on the basis of the current clothing processing device 100, thereby achieving the purpose of improving the washing ratio.

[0077] During the contact between the movable friction component 20 and the clothes, the movable friction component 20 may partially move relative to the washing tub 10 or may completely move relative to the washing tub 10 .

[0078] The washing tub 10 has an open end 11 and a closed end 12 in the axial direction, the open end 11 is provided with an open port, and in the pulsator 30 type laundry treating apparatus 100 , the closed end 12 is provided with a pulsator 30 .

[0079] In the pulsator 30 type clothing processing device 100, the open mouth of the washing tub 10 is opened to the upper side, and the pulsator 30 is located at the bottom of the washing tub 10 and directly opposite to the open mouth. That is to say, the washing tub 10 is placed vertically. After the clothes are put into the open mouth on the upper side, the clothes fall on the pulsator 30 at the bottom of the washing tub 10 under the action of gravity. During operation, the pulsator 30 will rotate intermittently in the forward and reverse directions, while the washing tub 10 is stationary and does not rotate. The clothes tumble and rotate up and down during the stirring process of the pulsator 30. During the tumbling and rotating of the clothes, the clothes and the clothes and the tub wall can be gently rubbed in the water, so that the dirt on the clothes can be removed. A movable friction component 20 is added to the inner wall surface of the washing tub 10. The movable friction component 20 can be partially or completely moved relative to the washing tub 10. Specifically, it can move up and down along the axial direction of the washing tub 10, which is equivalent to adding a washing dimension. When the clothes tumble up and down, the clothes rub against the movable friction component 20, which further enhances the cleaning power of the impeller 30 type clothing processing device 100 and improves the washing ratio.

[0080] In the drum-type laundry processing device 100, the open mouth of the washing tub 10 is open to the front side, and the washing tub 10 is placed horizontally. After the laundry is put into the open mouth on the front side, the laundry is directly attached to the inner wall surface of the washing tub 10. During operation, the drum rotates in one direction. Under the action of friction, the laundry is brought to a high place by the inner wall surface of the washing tub 10. When the friction is less than gravity, the laundry falls to the lowest inner wall surface. The laundry is constantly lifted and dropped in the washing tub 10, and then lifted and dropped again, performing repeated movements, and the laundry is cleaned in a form similar to knocking. The moving friction component 20 on the inner wall surface of the washing tub 10 will rotate with the washing tub 10 and provide friction on the inner wall surface where the moving friction component 20 is set. The friction cleaning between the laundry and the moving friction component 20 and the cleaning form similar to knocking further enhance the cleaning strength of the drum-type laundry processing device 100 and improve the washing ratio.

[0081] The movable friction assembly 20 includes: a movable member 21 and a mounting seat 23. The movable member 21 can move relative to the washing tub 10 during the washing process, and the mounting seat 23 is fixed to the inner wall surface of the washing tub 10. It can be understood that the movable member 21 is mounted on the mounting seat 23, and the movable member 21 can move on the mounting seat 23. During the washing process, the movable member 21 can move relative to the mounting seat 23, and the movable member 21 rubs against the clothes in the washing tub 10, thereby washing the clothes.

[0082] The mounting seat 23 is provided with a mounting space, the moving member 21 is provided in the mounting space, and a sidewall surface of the mounting seat 23 close to the washing space 101 is provided with a avoidance opening provided toward the washing space 101, the avoidance opening is communicated with the mounting space, the moving member 21 moves in the mounting space, and a friction portion 24 is provided on the moving member 21 toward the washing space 101, and the friction portion 24 can increase the contact area with the clothes, and rub when the clothes tumble and rotate. In other words, the avoidance opening is directly opposite to the friction portion 24, and the friction portion 24 on the moving member 21 is often exposed, and the clothes can contact and rub with the friction portion 24 to wash the clothes.

[0083] The friction portion 24 may be constructed as a plurality of friction strips 241 arranged at intervals, such as Figure 2 As shown, the friction strips 241 are raised and arranged in sequence along the length direction of the wall of the washing tub 10. The overall shape is similar to a washboard. The friction strips 241 can increase the friction between the clothes and the friction part 24, which is beneficial to the washing of the clothes.

[0084] The moving member 21 can be linked with the pulsator 30. During the rotation of the pulsator 30, the pulsator track 40 rotates with the pulsator 30, and the moving member can be linked with the pulsator 30. The pulsator 30 is rotatable relative to the washing tub 10. During the washing process, under the drive of the pulsator 30, the moving member 21 moves relative to the washing tub 10.

[0085] According to one embodiment of the present application, during the washing process, the moving member 21 moves along the circumferential direction of the washing tub 10. Specifically, a moving track can be opened on the inner wall of the washing tub 10 for the moving member 21 to move circumferentially. Of course, a mounting support can also be set on the inner wall of the washing tub 10 for the moving member 21 to move circumferentially. During the circumferential movement of the moving member 21, it can rub against the clothes, thereby further enhancing the ability of the clothing processing device 100 to clean the clothes.

[0086] The moving member 21 can be driven by an additional driving member, such as a driving motor. Under the driving action of the driving motor, the moving member 21 can move relative to the washing tub 10 to rub against the clothes in the washing tub 10.

[0087] A pulsator track 40 is provided on the pulsator 30 , one end of the moving member 21 is in the pulsator track 40 and contacts and stops with an inner surface 41 of the pulsator track. The moving member 21 can move along the circumferential direction of the washing tub 10 under the rotation drive of the pulsator 30 .

[0088] Since the inner surface 41 of the pulsator track is a wavy convex surface, the distance between the inner surface 41 of the pulsator track and the open opening of the washing tub 10 is different. Figure 4 As shown, when the moving member 21 stops against the part of the inner surface of the impeller track 40 close to the opening, the moving member 21 is lifted and moved upward; when the moving member 21 stops against the part of the inner surface of the impeller track 40 away from the opening, the moving member 21 can move downward under the action of gravity. The moving member 21 can move in the direction close to or away from the opening during the washing process. That is to say, when the moving member 21 slides on the impeller track 40, it can move back and forth in the up and down directions according to the distance between the inner surface 41 of the impeller track and the opening, thereby increasing the friction in the up and down dimensions and improving the washing ratio.

[0089] Further, the wave-shaped protrusion structure has at least one group of crests 411 and troughs 412, and when the crests 411 abut against the one end of the moving member 21, the other end of the moving member 21 is closest to the open end 11, and when the troughs 412 abut against the one end of the moving member 21, the other end of the moving member 21 is farthest from the open end 11. Thus, the moving member 21 can move in the up-down direction during the process of abutting against the surface between the crests 411 and the troughs 412.

[0090] The moving member 21 on the moving friction assembly 20 can move along the circumferential direction of the washing tub 10, and the moving direction of the moving member 21 can be the same as or opposite to the rotation direction of the pulsator 30. That is, when the moving direction of the moving member 21 is opposite to the rotation direction of the pulsator 30, the pulsator 30 rotates clockwise and the moving member 21 rotates counterclockwise, or the pulsator 30 rotates counterclockwise and the moving member 21 rotates clockwise; when the moving direction of the moving member 21 is the same as the rotation direction of the pulsator 30, the pulsator 30 rotates clockwise and the moving member 21 also rotates clockwise, or when the pulsator 30 rotates counterclockwise, the moving member 21 also rotates counterclockwise.

[0091] It should be noted that the clothes rotate together with the impeller 30 and the water flow in the washing tub 10, and it can be considered that the rotation direction of the clothes is the same as the rotation direction of the impeller 30, but due to the friction between the clothes and the inner wall of the washing tub 10, the rotation speed of the clothes must be lower than the rotation speed of the impeller 30. Therefore, as long as the rotation speeds of the moving part 21 and the clothes are different, even if they rotate counterclockwise or clockwise, the clothes and the moving part 21 must have relative motion, and then the clothes can rub against the moving part 21, thereby improving the washing ratio of the clothes processing device 100. Preferably, when the rotation direction of the impeller 30 is counterclockwise, the moving direction of the moving part 21 is clockwise; when the rotation direction of the impeller 30 is clockwise, the moving direction of the moving part 21 is counterclockwise.

[0092] The movable friction assembly 20 also includes an elastic member 22 , which is disposed in the installation space. Specifically, the elastic member 22 is disposed on the upper side of the movable member 21 . One end of the elastic member 22 is connected to the installation seat 23 , and the other end is connected to the movable member 21 .

[0093] The elastic member 22 can be in different states. For example, the elastic member 22 can be in a compressed state all the time, or in a stretched state all the time. The elastic member 22 can also be in a compressed state sometimes and in a stretched state sometimes.

[0094] Regardless of whether the moving part 21 is close to or far from the opening due to the action of the inner surface 41 of the impeller track during the washing process, the elastic part 22 is always in a compressed state. When the moving part 21 is close to the opening, the compression amount of the elastic part 22 is greater, and when the moving part 21 is far from the opening, the compression amount of the elastic part 22 is less.

[0095] Regardless of whether the moving part 21 is close to or far from the opening due to the action of the inner surface 41 of the impeller track during the washing process, the elastic part 22 is always in a stretched state. When the moving part 21 is close to the opening, the elastic part 22 is stretched to a greater extent, and when the moving part 21 is far from the opening, the elastic part 22 is stretched to a lesser extent.

[0096] The above two situations are both likely to implement the solution of the present application. When the elastic member 22 is always in a compressed state, the movable member 21 needs to overcome the downward pressing force of the elastic member 22 to move upward, which will increase the pressure on the impeller track 40. The inner surface 41 of the impeller track supports the movable member 21 to lift up, but in the process of the movable member 21 moving downward, there is not only the effect of the movable member 21's own gravity but also the effect of the elastic member 22's restoring force. Under the dual effect, the movable member 21 is easier to return to its initial position; when the elastic member 22 is always in a stretched state, the movable member 21 is pressed against the inner surface of the impeller track under the effect of the pulling force, and the movable member 21 needs to overcome the downward pulling force of the elastic member 22 to move upward, which will increase the pressure on the impeller track 40. The inner surface 41 of the impeller track supports the movable member 21 to lift up, but in the process of the movable member 21 moving downward, there is not only the effect of the movable member 21's own gravity but also the pulling force of the elastic member 22. Under the dual effect, the movable member 21 is easier to return to its initial position.

[0097] A roller 50 is provided at one end of the moving part 21. The roller 50 can be stuck in the impeller track 40. The roller 50 contacts the inner surface 41 of the impeller track. This can ensure that one end of the moving part 21 always stops at the inner surface 41 of the impeller track and can move up and down with the changes of the inner surface 41 of the impeller track.

[0098] Of course, the roller 50 can also rotate on the inner surface 41 of the impeller track to change the sliding friction into rolling friction, thereby reducing the friction between the moving part 21 and the inner surface 41 of the impeller track.

[0099] When the moving part 21 is closer to the opening during the washing process, the elastic part 22 is in a compressed state. When the moving part 21 is farther away from the opening during the washing process, the elastic part 22 is in a stretched state. This embodiment is the most ideal state of the elastic part 22. The inner surface 41 of the impeller track supports the moving part 21 and lifts it upward. At this time, the elastic part 22 is in a compressed state. When the moving part 21 moves downward, the spring restoring force and the gravity of the moving part 21 work together to return the moving part 21 to its initial position.

[0100] There is also a friction reducing portion between the moving member 21 and the mounting seat 23, such as Figure 3As shown, there is a slider 211 on the movable member 21, and the slider 211 is arranged in a convex shape in the length direction of the movable member 21. There is a slide groove 2301 corresponding to the slider 211 in the installation space, and the slide groove 2301 is opened in the length direction of the mounting seat 23, and the slider 211 can slide in the slide groove 2301, that is, the slider 211 can slide along the slide groove 2301 in the up and down directions to approach or move away from the open mouth, and the friction reducing part is constructed as a plurality of arc protrusions 60 on the slider 211, and the plurality of arc protrusions 60 stop against the inner wall surface of the slide groove 2301. It can be understood that after designing a plurality of arc protrusions 60, the slide groove 2301 and the slider 211 are changed from surface-to-surface contact to point-to-surface contact, which can reduce the friction between the slider 211 and the slide groove 2301.

[0101] In the present application, there may be multiple movable friction components 20, and the multiple movable friction components 20 are arranged circumferentially on the inner wall surface of the washing tub 10. The more movable friction components 20 there are, the higher the cleaning degree of the clothes.

[0102] The clothing processing device 100 also includes a fixed friction component, which is constructed as a plurality of protrusions on the inner wall surface of the washing barrel 10 facing the washing space 101. When the clothes fall, tumble or rotate, they will rub against the fixed friction component, which can be understood as an action similar to rubbing clothes, so as to achieve the purpose of cleaning and improve the cleaning ratio of the clothing processing device 100.
