[0046] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0048] In the following description, the terms "first\second\..." involved are only used to distinguish different objects, and do not indicate that there are similarities or connections between the objects. It should be understood that the orientation descriptions "above", "below", "outside" and "inside" involved are all orientations in normal use, and the "left" and "right" directions represent the left and right directions indicated in the specific corresponding schematic diagrams, which may be the left and right directions in normal use or not. It should be noted that the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also include elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the statement "including one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0049] The embodiment of the present invention provides a clothes processing device, which may be a washing machine, a washer-dryer, etc. It should be noted that the application scenario type of the embodiment of the present invention does not limit the clothes processing device of the embodiment of the present invention.

[0050] The following description takes the clothing processing device being a washing machine as an example. Figure 1 The figure shows a schematic cross-sectional view of the washing machine in a washing state, where the cross section is a cross section perpendicular to the rotation axis of the washing machine. The laundry treatment device provided by the embodiment of the present invention comprises a washing tub 1 and a drain valve 6 . Figure 4 The arrows indicate the circumferential direction of the washing tub.

[0051] like Figure 1As shown, the washing tub 1 has a washing chamber 11 inside, and the washing chamber 11 can be used to accommodate clothes to be processed. The steps of processing clothes by the clothes processing device include but are not limited to soaking, washing and dehydrating. The washing tub 1 is provided with a drainage hole 12 connected to the washing chamber 11, and the drainage hole 12 connects the washing chamber 11 and the outside of the washing chamber 11. It should be noted that the clothes processing device in the embodiment of the present invention can be a single-barrel washing machine or a double-barrel washing machine. For example, when the clothes processing device is set as a single-barrel washing machine, the drainage hole 12 can connect the washing chamber 11 and the outside of the clothes processing device. When the drainage hole 12 is open, the water in the washing chamber 11 can be directly discharged to the outside of the clothes processing device through the drainage hole 12. Of course, a water collecting pan may also be provided in the shell of the clothing treatment device located outside the washing tub 1, and a water collecting chamber is formed between the water collecting pan and the washing tub. The drain hole 12 may connect the washing chamber and the water collecting chamber. When the clothing treatment device is in a dehydration working state, the drain hole 12 is opened, and the drain hole 12 guides the water in the washing chamber 11 into the water collecting chamber, and the water collecting pan then guides the water in the water collecting chamber to the outside of the clothing treatment device. In the case where the clothing treatment device is configured as a double-barrel washing machine, the clothing treatment device includes a washing tub 1 and a shell 4, and the gap between the shell 4 and the washing tub 1 may form a water collecting chamber, and the water collecting chamber is connected to the drain hole 12. Except for the washing tub 1 being connected to the water collecting chamber through the drain hole 12, the other parts of the washing tub 1 are closed relative to the water collecting chamber, that is, the water in the washing chamber 11 can only be guided into the water collecting chamber from the drain hole 12, and then the water in the water collecting chamber is guided to the outside of the clothing treatment device. It should be noted that no matter whether the clothing processing device in the embodiment of the present invention is a single-barrel washing machine or a double-barrel washing machine, the drainage hole in the embodiment of the present invention can be directly or indirectly connected to the outside of the clothing processing device to drain the water in the washing chamber 11 to the outside of the clothing processing device.

[0052] like Figure 1As shown, the drain valve 6 includes a track body 2 and a movable mechanism 3. The track body 2 is arranged in the washing chamber 11 and is directly or indirectly connected to the washing tub 1. The following content will specifically describe the implementation methods of direct connection and indirect connection. Among them, the track body 2 defines a motion channel, and the movable mechanism 3 can move in an arc along the motion channel to close and open the drain hole. The movable mechanism 3 closes the drain hole 12, which means that the movable mechanism 3 can completely cover the drain hole 12, so that the liquid in the washing chamber 11 cannot flow out of the drain hole 12 to the outside of the washing tub 1; the movable mechanism 3 opens the drain hole 12, which means that the movable mechanism 3 is spaced from the drain hole 12, so that the liquid in the washing chamber 11 can flow out of the drain hole 12 to the outside of the washing tub 1. Among them, there are many ways to define the structure of the track body 2 and the way to define the motion channel. The motion channel can be formed in an open space or in a closed space. The following will list several ways to explain the motion channel. However, those skilled in the art can understand that the embodiments of the present invention are not limited to the following methods. Other ways that can define the motion channel by the track body so that the movable mechanism can move along its arc are all acceptable.

[0053] In addition, the movable mechanism moves in an arc shape to illustrate that the trajectory of the movable mechanism is an arc shape. It can be understood that the arc shape of the motion trajectory of the movable mechanism does not limit the relative motion between the parts or components of the movable mechanism, but only the whole movable mechanism, such as the motion trajectory of its contour, basically presents an arc motion different from the linear motion. Among them, the curvature radius of the arc can be a value, and the arc can also be a shape formed by smoothly connecting multiple arcs with different curvature radii; it can be understood that the arc trajectory has a longer trajectory length than the linear trajectory.

[0054] The embodiment of the present invention sets a motion channel on the track body, and the movable mechanism can move along the arc of the motion channel to open and close the drainage hole. On the one hand, the movable mechanism can open and close the drainage hole by moving, making the drainage method simpler; on the other hand, the movement of the movable mechanism is in an arc shape, and the length of the motion trajectory is longer. Compared with the structure without a track body, the movable mechanism consumes more kinetic energy during the movement process, so when it moves to the position of closing the drainage hole, the impact energy of the movable mechanism on the wall of the washing tub is small, and thus the noise generated is small. The embodiment of the present invention can simplify the drainage method of the clothing processing equipment while having less noise, which is conducive to reducing costs and improving user experience.

[0055] In some embodiments, the motion channel includes a support surface, the support surface is formed in an arc shape, and the arc opening of the support surface faces the side wall of the washing tub. It can be understood that the support surface can be a plane or a curved surface, and its overall extension direction is an arc shape. For example, a line segment is rotated at a certain angle with a point outside the line segment as the center of the circle to form an arc-shaped support surface. Then, the direction of the arc toward the center of the circle corresponding to the arc can be considered as the direction of the arc opening. By setting the arc opening of the support surface toward the side wall of the washing tub, that is, the arc support surface formed by the track body 2 protrudes toward the axis direction of the rotating shaft of the washing tub to form an inward convex shape, so that during the rotation of the washing tub around the above-mentioned axis, the movable mechanism 3 moves along the support surface to open and close the drainage hole as the washing tub rotates. The embodiment of the present invention is conducive to guiding the arc movement of the movable mechanism by setting the support surface in an arc shape, reducing the impact on the movable mechanism during the arc movement, and thus helping to reduce the noise generated by the movement of the movable mechanism.

[0056] In some embodiments, the track body 2 is arc-shaped. It can be understood that the overall contour of the track body 2 is arc-shaped, and the movable mechanism 3 moves along the arc-shaped support surface of the track body 2 and also moves along the arc-shaped track body 2. Among them, the arc of the track body 2 extends along the axial direction of the washing tub. It can be understood that the extension direction of the arc is the length direction, which is the direction from one end to the other end of the arc. In this embodiment, the extension direction of the arc track body is along the axial direction of the washing tub, so that the requirements for the chamber for installing the movable mechanism can be reduced. For example, the movable mechanism and the track body can be set in the lifting ribs to make full use of the longer length of the lifting ribs along the axial direction of the washing tub.

[0057] Among them, the movable mechanism 3 is suitable for sliding and / or rolling along the support surface. It can be understood that the movable mechanism 3 can move relative to the support surface along the support surface, that is, slide along the support surface; it can also move relative to the support surface and rotate, as long as the overall motion trajectory of the movable mechanism 3 is arc-shaped. The embodiment of the present invention is conducive to improving the diversity of the implementation methods of the movable mechanism by setting the movable mechanism to slide and / or roll, and when the movable mechanism can at least partially roll, it can reduce the friction between the movable mechanism and the support surface, thereby improving the smoothness of the movement process of the movable mechanism.

[0058] In some embodiments, the movable mechanism 3 is provided with an arc structure adapted to the supporting surface on the side facing the supporting surface, and the arc structure is suitable for sliding along the supporting surface. It can be understood that the arc structure on the movable mechanism 3 can be formed in a variety of ways. For example, the arc structure can be an arc surface, or multiple convex ribs extending in an arc shape, and there is a space between each convex rib, etc. As long as the contour of the movable mechanism 3 on the side facing the supporting surface is arc-shaped, the arc structure contacts the arc-shaped supporting surface and is suitable for sliding along the supporting surface. Then, the arc structure is slidable relative to the supporting surface, and the other parts of the movable mechanism 3 can be fixedly connected or rotatably connected to the arc structure, so that the movable mechanism 3 can slide or at least partially roll along the supporting surface. The embodiment of the present invention is conducive to improving the smoothness of the movement of the movable mechanism along the supporting surface and reducing the friction during the relative movement between the movable mechanism and the supporting surface by providing an arc structure adapted to the supporting surface on the movable mechanism.

[0059] The following is an exemplary description of the specific manner in which the track body forms the support surface: In the first manner, the track body 2 itself can be similar to a flat or curved part, and can be approximately regarded as a two-dimensional component, and there is no cavity formed inside the track body 2, and the entire or most of the surface of the track body 2 forms the support surface. In the second manner, the track body 2 is a three-dimensional component with a cavity inside, and a portion of the surface of the track body 2 forms the support surface, wherein the cavity can be open on one side of the support surface, that is, the opening is adjacent to the support surface, or the opening can be opposite to the support surface, or the opening can include multiple directions, both adjacent to and opposite to the support surface.

[0060] The following description will be made by taking the case where the track body 2 has a cavity 22 as an example. Figure 1-Figure 4 As shown, the movable mechanism 3 can move along the cavity 22 to close and open the drainage hole 12.

[0061] The connection modes of the drain valve 6 and the washing tub 1 in the embodiment of the present invention include two types. In one embodiment, Figure 1 As shown, the track body 2 is directly connected to the washing tub 1, and the track body 2 is arranged in the washing chamber 11. In another embodiment, as shown in FIG. Fig.17 As shown, a lifting rib 5 for raising the height of clothes is provided in the washing tub 1, the lifting rib 5 is hollow inside, a drain valve 6 is arranged in the lifting rib 5, and the drain valve 6 is connected to the lifting rib 5, thereby realizing an indirect connection with the washing tub 1.

[0062] The following is an explanation of the direct connection between the drain valve 6 and the washing tub 1:

[0063] like Figure 1As shown, the track body 2 is disposed in the washing chamber 11, and the track body 2 is directly connected to the washing tub 1. The track body 2 in the embodiment of the present invention can be detachably connected to the washing tub 1 by means of a snap-on structure, and the track body 2 can also be permanently fixed to the washing tub 1 by welding. Regardless of the connection method between the track body 2 and the washing tub 1, it is sufficient as long as the track body 2 can remain stationary relative to the washing tub 1 during the clothing processing process. The washing tub 1 in the embodiment of the present invention can be roughly configured as a cylindrical structure, and the washing tub 1 includes a bottom wall and a side wall arranged around the edge of the bottom wall, and the side wall is arranged around the axial direction of the washing tub 1. The embodiment of the present invention does not limit the specific connection position between the track body 2 and the washing tub 1. For example, the track body 2 can be set at any position on the side wall of the washing tub.

[0064] like Figure 1-4 As shown, the cavity 22 in the track body 2 is connected to the washing cavity 11 , and the liquid in the washing cavity 11 can flow to the drain hole 12 through the cavity 22 , or the liquid in the washing cavity 11 can be discharged directly from the drain hole 12 without passing through the cavity 22 .

[0065] Combination Figure 2 and Figure 4 As shown, the path of liquid flow in the washing chamber 11 is described:

[0066] One end of the cavity 22 forms an opening 21 ( Figure 2 and Figure 4 The right end of the track body 2 shown in FIG. 1 ) and the other end is a closed end 23 ( Figure 2 and Figure 4 The left end of the track body 2 shown in the figure), the opening 21 connects the cavity 22 and the washing cavity 11, and the closed end 23 separates the cavity 22 from the washing cavity 11. The drain hole 12 is located outside the cavity 22, and the drain hole 12 is opposite to the opening 21. The above "relative" is used to illustrate the positional relationship between the opening 21 and the drain hole 12. The track body 2 is provided with one end of the opening 21. If it continues to extend along the contour of the track body 2, since the drain hole 12 is opposite to the opening 21, the cavity 22 will cover the drain hole 12. The opening 21 is spaced a certain distance from the drain hole 12, such as Figure 4 As shown, when the drain hole is open, the water in the washing chamber 11 can flow directly from the gap between the drain hole 12 and the opening 21 to the drain hole 12, and then be discharged from the drain hole 12 to the outside of the clothes processing device. Of course, when the amount of water in the washing chamber 11 is large, the water can also enter the cavity 22. In the embodiment of the present invention, the cavity 22 is set to be open at one end, and the water in the washing chamber 11 can flow directly from the gap between the opening 21 and the drain hole 12 to the drain hole 12, thereby improving the dehydration efficiency of the clothes processing device.

[0067] Combination Figure 1-Figure 4As shown, the movable mechanism 3 can move between the first position and the second position along the cavity 22 to open and close the drain hole 12. It should be noted that the specific shape of the cavity 22 does not necessarily affect the movement trajectory of the movable mechanism 3, and the change of the relative position between the movable mechanism 3 and the cavity 22 can be achieved by the movement of the movable mechanism 3. Figure 2 As shown, the first position indicates the position where the movable mechanism 3 protrudes from the opening 21 and closes the drain hole 12. The protruding opening 21 may be that at least a portion of the movable mechanism 3 is located in the cavity 22, and the other portion is located outside the cavity 22. The portion of the movable mechanism 3 protruding from the opening 21 closes the drain hole 12, so that the water in the washing cavity 11 cannot flow out of the drain hole 12. In this state, there is a space between the movable mechanism 3 and the closed end 23 of the track body 2, so as to provide a movable space for the movable mechanism 3 to move to the second position.

[0068] like Figure 3-4 As shown, the second position represents the position where the movable mechanism 3 abuts against the closed end 23 of the track body 2. It should be noted that abutting means that the movable mechanism 3 is in contact with the closed end 23. The movable mechanism 3 and the closed end 23 may or may not have a mutual pressing force when abutting. The closed end 23 and the opening 21 are respectively located at the two ends of the extension direction of the cavity 22. The extension direction of the cavity 22 is the maximum dimension direction of the cavity 22. That is to say, in the process of moving from the first position to the second position, the movable mechanism 3 moves from the position of partially protruding from the opening 21 to the position abutting against the closed end 23. When the movable mechanism 3 is in the second position, the movable mechanism 3 may be completely located in the cavity 22, or may still be partially located outside the opening 21 but the drain hole 12 has been opened. The movable mechanism 3 is away from the drain hole 12, that is, the drain hole 12 is opened, and the water in the washing chamber 11 can be discharged from the drain hole 12.

[0069] The embodiment of the present invention can realize automatic opening and closing of the drain hole by arranging the drain hole at a position opposite to the opening of the track body, and the movable mechanism moves between the first position and the second position. The drainage structure of the embodiment of the present invention is simple, which is conducive to reducing the manufacturing difficulty and cost of the clothing processing device. In addition, when the movable mechanism is located at the open drain hole, the water in the washing chamber can directly flow to the drain hole through the gap between the opening and the drain hole, which reduces the restriction and blocking risk of the movable mechanism on the water flow, and is conducive to increasing the speed of the water flow out of the drain hole, so that the shell improves the efficiency of liquid discharge to the outside of the clothing processing device.

[0070] In some embodiments, Figure 1-4 As shown, the cavity 22 is configured as an arc structure. It should be noted that the arc structure means that the extension direction of the cavity 22 is not along a straight line direction, but along an arc direction with a certain curvature, and the closed end 23 and the opening 21 are respectively located at the two ends of the cavity 22 in the arc direction. Figure 4As shown, the arc direction can be defined as the direction of the line connecting the closed end 23 and the opening 21 at the closest position (which can be considered as the extension direction of the inner wall 26 of the cavity 22), the arc direction can also be defined as the direction of the line connecting the closed end 23 and the opening 21 at the farthest position (which can be considered as the extension direction of the outer wall 25 of the cavity 22), the arc direction can also be defined as the direction of the line connecting the middle position of the closed end 23 and the middle position of the opening 21 (which can be considered as the extension direction of the center line of the cavity 22), of course, the arc directions defined in the three ways listed above can be parallel directions, and hereinafter, for the convenience of description, the arc direction represents the direction of the line connecting the middle position of the closed end 23 and the middle position of the opening 21 (which can be considered as the extension direction of the center line of the cavity 22). In some embodiments, the curvature of the arc representing the extension direction of the cavity 22 may be a fixed value, for example, the arc is a circular arc, and its corresponding curvature is constant; in other embodiments, the curvature of the arc representing the extension direction of the cavity 22 may be variable, for example, the arc is formed by connecting several circular arcs with different curvatures, then the curvature corresponding to the arc may be variable but the curvature does not suddenly change, that is, the cavity 22 has no inflection point. In the embodiment of the present invention, by setting the cavity to an arc shape, the arc-shaped structure limits the motion range of the movable mechanism to the arc area, which is conducive to reducing the risk of collision between the movable structure and the track body, thereby helping to reduce the noise generated by the collision.

[0071] In some embodiments, Figure 4 As shown, the track body 2 includes an outer wall surface 25 and an inner wall surface 26, wherein the inner wall surface 26 is closer to the washing tub wall relative to the outer wall surface 25, that is, the inner wall surface 26 is farther from the axis of the washing tub relative to the outer wall surface 25, and a cavity 22 for accommodating the movable mechanism 3 is defined between the outer wall surface 25 and the inner wall surface 26, and the inner wall surface 26 is connected to the outer wall surface 25 through a bottom wall. In some embodiments, the inner wall surface 26 is formed as a support surface, that is, the movable mechanism 3 moves in an arc shape along the inner wall surface 26. In other embodiments, the support surface is formed as an arc groove provided on the bottom wall, that is, the movable mechanism 3 moves in an arc shape along the arc groove formed on the bottom wall. The support surface of the embodiment of the present invention can be formed on each wall surface of the track body, thereby increasing the diversity of the track body implementation methods.

[0072] In some embodiments, Figure 4 As shown, the outer wall surface 25 and the inner wall surface 26 are curved in the same direction, and the arc length of the outer wall surface 25 is greater than the arc length of the inner wall surface 26. The centers of the arcs corresponding to the outer wall surface 25 and the inner wall surface 26 are located on the same side, indicating that the two have the same curvature direction. Figure 4As shown, both the outer wall 25 and the inner wall 26 protrude into the washing chamber 11, indicating that the two have the same bending direction. It should be noted that the same bending direction of the outer wall 25 and the inner wall 26 does not mean that the curvature of the two needs to be the same. The curvatures of the outer wall 25 and the inner wall 26 can be the same or different. In the case where an arc is used to represent the extension direction of the cavity 22 (the arc can be selected in a variety of ways as described above), since the outer wall 25 is outside the inner wall 26, the projection length of the outer wall 25 on the arc is greater than the projection length of the inner wall 26 on the arc. The embodiment of the present invention is conducive to guiding the movable mechanism to move in the arc-shaped cavity by setting the inner wall and the outer wall of the cavity 22 as arc surfaces.

[0073] In other embodiments, the inner wall surface 26 may also be set to a plane, so as to increase the contact area between the inner wall surface 26 and the washing tub, which is beneficial to improving the stability of the connection between the track body and the washing tub.

[0074] In some embodiments, in combination Figure 4 As shown, the curvature of the inner wall surface 26 is greater than or equal to 165 degrees and less than or equal to 180 degrees. The curvature of the inner wall surface 26 is measured by the longitudinal section (i.e. Figure 4 The angle of the arc of the inner wall surface 26 represented by the cross section parallel to the extension direction of the track body is shown. Figure 4 As shown, the curvature of the outer wall surface 25 is greater than or equal to 135 degrees and less than or equal to 170 degrees. The curvature of the outer wall surface 25 is measured by the longitudinal section (i.e. Figure 4 The angle of the arc of the outer wall 25 represented on the cross section parallel to the extension direction of the track body shown in FIG. 1 is represented by the angle of the arc of the outer wall 25 represented on the cross section parallel to the extension direction of the track body shown in FIG. 1 . The arc of the outer wall 25 can be smaller than the arc of the inner wall 26. Specifically, the inner wall 26 can extend half a circle, that is, 180 degrees, and one end of the outer wall 25 is connected to the closed end 23, and the other end of the outer wall 25 is a free end, that is, the other end of the outer wall 25 is not connected to or in contact with other physical components, so that the extension angle of the outer wall 25 is less than half a circle. The free end of the outer wall 25 can form an opening 21 with the end of the inner wall 26 away from the closed end 23, and the opening 21 is spaced apart from the drain hole 12. The water in the washing chamber 11 can flow directly from the gap between the opening 21 and the drain hole 12 to the drain hole 12, and does not need to flow through the cavity 22 before flowing to the drain hole 12, thereby improving the dehydration efficiency of the clothing processing device.

[0075] In some embodiments, Figure 4As shown, both ends of the arc length direction of the inner wall surface 26 are connected to the washing tub 1, and the distance L3 between the end of the outer wall surface 25 located at the opening 21 and the washing tub 1 is greater than or equal to the first preset value and less than or equal to the second preset value, the first preset value is 1 / 5*the width of the opening 21, and the second preset value is 1 / 2*the width of the opening 21. In the embodiment of the present invention, by limiting the distance between the end of the outer wall surface located at the opening and the washing tub to be less than or equal to the second preset value, the movement amplitude of the movable mechanism will not be too large, thereby reducing the noise generated by the movement of the movable mechanism; in the embodiment of the present invention, by limiting the distance between the end of the outer wall surface located at the opening and the washing tub to be greater than or equal to the first preset value, the distance between the outer wall surface and the washing tub will not be too small, thereby facilitating the smooth flow of water from the gap between the outer wall surface and the washing tub to the drain hole.

[0076] In some embodiments, the movement direction of the movable mechanism 3 is consistent with the extension direction of the cavity 22, which can further reduce the impact of the cavity on the movement of the movable mechanism, thereby improving the smoothness of the movement of the movable mechanism and reducing the noise generated by the movement of the movable mechanism, thereby improving the user experience.

[0077] In some embodiments, Figure 4 As shown, the outer surface of the movable mechanism 3 is in smooth contact with the inner surface of the track body 2, that is, it can be in smooth contact with both the inner wall surface 26 of the cavity 22 and the outer wall surface 25 of the cavity 22. Smooth contact means that the contour change trend of the outer surface of the movable mechanism 3 is consistent with the contour change trend of the inner surface of the track body 2, so that the outer surface of the movable mechanism 3 and the inner surface of the track body 2 fit each other, which is conducive to improving the smoothness of the relative movement of the movable mechanism to the track body, and is also conducive to reducing the noise generated by the collision between the track body and the movable mechanism, thereby improving the user experience.

[0078] In some embodiments, Figure 1 As shown, the movable mechanism 3 is configured as an arc structure. Specifically, from the overall shape of the movable mechanism 3, its length direction (the direction with the largest size) is not a straight line direction but an arc direction with curvature. In order to distinguish it from the arc direction of the cavity above, the arc direction of the extension of the movable mechanism 3 is called the second arc direction. It can be understood that the arc direction and the second arc direction can be parallel, that is, the extension direction of the cavity is the same as the extension direction of the movable mechanism, or they can be non-parallel, that is, the extension direction of the cavity and the extension direction of the movable mechanism can be different. In the embodiment of the present invention, the movable mechanism 3 is configured as an arc structure, and during the movement of the movable mechanism relative to the cavity, the movement direction of the movable mechanism is consistent with the extension direction of the movable mechanism itself, which is conducive to the fitting and separation of the movable mechanism and the drain hole through the movement of the movable mechanism, and is conducive to the movement of the movable mechanism in a small space to realize the opening and closing of the drain hole.

[0079] In some embodiments, Figure 4 As shown, the length of the movable mechanism 3 is greater than or equal to 0.7 times the first dimension and less than or equal to 0.9 times the first dimension. Among them, the first dimension is the length from the first position to the second position in the arc direction, and the arc direction represents the extension direction of the cavity. It should be noted that the length of the movable mechanism 3 is the length in the direction of the maximum dimension of the movable mechanism. When the movable mechanism 3 is set to an arc structure, the length of the movable mechanism 3 can be the maximum dimension in the second arc direction of the movable mechanism itself. In the embodiment of the present invention, by setting the length of the movable mechanism 3 to be less than or equal to 0.9 times the first dimension, the distance between the movable mechanism and the drain hole will not be too close, so as to reduce the interference of the movable mechanism on the drain hole in the second position state, thereby facilitating the speed of liquid diversion from the washing chamber to the drain hole; the length of the movable mechanism is set to be greater than or equal to 0.7 times the first dimension, so that the movable space between the movable mechanism and the track body will not be too large, further limiting the movement amplitude of the movable mechanism, thereby reducing the noise generated by the movement of the movable mechanism, which is conducive to improving the user experience.

[0080] In some embodiments, Figure 2As shown, the movable mechanism 3 includes a slider 31, a counterweight 32 and an elastic member 33. In some embodiments, the slider 31 can slide relative to the track body 2, and in other embodiments, it can also roll at least partially relative to the track body. The slider 31 has a first end 311 and a second end 312 relative to each other in the extension direction. The extension direction represents the maximum dimension direction of the slider 31. When the slider 31 extends along the arc direction, the first end 311 and the second end 312 of the slider 31 are at opposite ends of the arc direction. The first end 311 is close to the drain hole 12, and the second end 312 is close to the closed end 23 of the track body 2. It can be understood that the first end 311 is close to the drain hole 12 relative to the positional relationship between the second end 312 and the drain hole 12. Similarly, the second end 312 is close to the closed end 23 of the track body relative to the positional relationship between the first end 311 and the closed end 23. When the movable mechanism 3 is in the first position, the first end 311 of the slider 31 contacts the drain hole 12, and the second end 312 is spaced from the closed end 23; when the movable mechanism 3 is in the second position, the second end 312 of the slider 31 contacts the closed end 23, and the first end 311 is spaced from the drain hole 12. The counterweight 32 is arranged close to the second end 312 of the slider 31, and "close" means that the distance between the counterweight 32 and the second end 312 is shorter than the distance between the counterweight 32 and the first end 311, for example, the distance from the counterweight to the second end is less than 1 / 2 of the distance between the first end and the second end. The elastic member 33 is arranged between the slider 31 and the track body 2, and the elastic member 33 has the ability to deform and restore deformation. The elastic member 33 in the embodiment of the present invention includes but is not limited to a spring and an elastic ball. Taking the elastic member 33 as an example, the two ends of the spring are not necessarily fixedly connected with the slider 31 and the track body 2, as long as the spring abuts between the slider 31 and the track body 2, it is considered to be connected. In some embodiments, the weight block 32 independent of the slider 31 may not be provided, but the mass of the portion of the slider 31 close to the second end may be set larger. The first end 311 of the slider may be regarded as a valve core, which is used to open and close the drain hole 12 under the combined action of the elastic force of the spring, the centrifugal force of the weight block, gravity, etc.

[0081] Combination Figure 1-Figure 4 , the movement process of the slider 31 is described below:

[0082] Figure 1 and Figure 2The clothes processing device is in a non-dehydration state, which includes a soaking state, a washing state, and a non-working state, and the first end 311 of the slider 31 abuts against the drain hole 12 under the elastic force of the elastic member 33, and the movable mechanism 3 is located at the first position of closing the drain hole 12. In the non-dehydration state, the rotation speed of the washing tub 1 is low or zero, and the centrifugal force generated by the counterweight 32 due to the slow rotation speed or non-rotation of the washing tub 1 is low or zero, and the centrifugal force is insufficient to overcome the elastic force generated by the elastic member 33 on the slider 31, so the slider 31 is stably maintained at the first position of closing the drain hole 12.

[0083] Figure 3 and Figure 4 The clothes processing device in the washing machine is in the dehydration state, and the washing tub 1 is circumferentially ( Figure 4 The washing tub 1 rotates in the direction indicated by the middle arrow (in the direction indicated by the middle arrow), and the rotation speed of the washing tub 1 in the dehydration state is relatively high. As the rotation speed increases, the centrifugal force F of the counterweight block 32 becomes larger. When the centrifugal force F generated by the counterweight block 32 due to the rotation of the washing tub 1 is greater than a certain value, the centrifugal force F can overcome the elastic force applied by the elastic member 33 to the slider 31, so that the centrifugal force F generated by the counterweight block 32 can drive the slider 31 to move relative to the track body 2, and the slider 31 moves from the first position protruding from the opening 21 to the second position abutting against the closed end 23. In the state of being located at the second position, the second end 312 of the slider 31 abuts against the closed end 23, and the first end 311 of the slider 31 opens the drain hole 12, so that the water in the washing chamber 11 can be discharged from the drain hole 12 to the outside of the clothing processing device.

[0084] In some embodiments, in combination Figure 4-Figure 6 As shown, when the movable mechanism 3 is an overall arc-shaped structure and extends along the second arc direction, the slider 31 extends from the first end 311 to the second end 312 along the second arc direction, the slider 31 is configured as an arc-shaped structure, the elastic member 33 is disposed at a position of the slider 31 close to the first end 311, and the counterweight block 32 is disposed at a position of the slider 31 close to the second end. That is to say, the elastic member 33 and the counterweight block 32 are distributed at both ends of the arc-shaped structure, which is beneficial to guiding the slider 31 to move relative to the track body 2, thereby improving the reliability of the slider in opening and closing the drainage hole.

[0085] In some embodiments, Figure 2As shown, the slider 31 has an arc greater than or equal to 90 degrees and less than or equal to 160 degrees from the first end 311 to the second end 312. The slider 31 can be connected along the arc direction from the first end 311 to the second end 312 to form a partial circumference, and the arc of the partial circumference is greater than or equal to 90 degrees and less than or equal to 160 degrees. The embodiment of the present invention limits the upper limit value of the arc of the slider from the first end to the second end, so that the structural change of the slider will not be too large, thereby reducing the interference of the slider on the flow of liquid at the drainage hole; and limits the lower limit value of the arc of the slider from the first end to the second end, so that the structural change of the slider will not be too small, thereby reducing the difficulty of manufacturing the slider.

[0086] In some embodiments, in combination Figure 4 and Figure 5 As shown, the slider 31 is provided with a receiving cavity 314 for receiving the counterweight 32 at a position near the second end 312, and the counterweight 32 is connected to the receiving cavity 314. It should be noted that the connection between the counterweight 32 and the slider 31 includes that the counterweight 32 is arranged in the receiving cavity 314, so that the receiving cavity 314 limits the position of the counterweight 32, so that the counterweight 32 will not be separated from the receiving cavity 314, and it is not necessarily required that the counterweight 32 and the slider 31 have a direct connection relationship. In other embodiments, the counterweight can be integrally formed with the slider, that is, in the manufacturing process of the movable mechanism, the counterweight can be integrally injection molded with the slider, the counterweight can be injection molded into a structure with higher density and heavier mass, and the slider can be injection molded into a structure with lighter mass; or the counterweight 32 can be fixedly connected to the slider 31.

[0087] The embodiment of the present invention arranges the counterweight block in the accommodating cavity and connects it to the slider, so that the counterweight block and the slider are arranged integrally. On the one hand, the counterweight block can be produced separately from the slider, which reduces the manufacturing difficulty and thus reduces the production cost of the clothing processing device. On the other hand, the integral assembly of the counterweight block and the slider is conducive to simplifying the structure of the movable mechanism and simplifying the movement mode of the movable mechanism, thereby simplifying the drainage method of the single-barrel clothing processing device.

[0088] In some embodiments, Figure 6 As shown, the slider 31 includes a main body 317 and a mounting portion 318 connected in sequence from the first end 311 to the second end 312, the mounting portion 318 surrounds the accommodating cavity 314, and the second end 312 is located at the mounting portion 318. Specifically, the mounting portion 318 can be roughly set to a spherical structure, and the accommodating cavity 314 formed inside the mounting portion 318 can also be set to a cylindrical, spherical, etc. The mounting portion 318 in the embodiment of the present invention is fixedly connected to the main body 317. In some embodiments, the mounting portion 318 can be integrally injection molded with the main body 317. The embodiment of the present invention makes the assembly method of the counterweight block and the slider simple by dividing the slider into a main body and a mounting portion, which is conducive to improving the assembly efficiency of the movable mechanism.

[0089] In some embodiments, Figure 6 As shown, the mounting portion 318 is provided with an opening 3141 communicating with the accommodating cavity 314, and the counterweight 32 can be manufactured separately from the slider 31. During the assembly process, the counterweight 32 can be assembled into the accommodating cavity 314 through the opening 3141. Specifically, the size of the opening 3141 can be smaller than the maximum cross-sectional area of ​​the counterweight 32, and at least a portion of the counterweight 32 can be set as an elastic structure, that is, the counterweight 32 can be elastically deformed in accordance with the opening 3141 with a smaller size during the assembly process. After the counterweight 32 is completely moved to the accommodating cavity 314, the counterweight 32 resumes the elastic deformation, so that the maximum cross-sectional area of ​​the counterweight 32 is larger than the size of the opening, thereby limiting the counterweight 32 from leaving the accommodating cavity 314 from the opening 3141 after assembly. Of course, in other embodiments, the portion of the mounting portion 318 close to the opening 3141 may be provided as an elastic structure, so that during the assembly of the counterweight 32 and the mounting portion 318, the size of the opening 3141 will elastically increase, and after the assembly is completed, the size of the opening 3141 will return to a size smaller than the maximum cross-sectional area of ​​the counterweight 32. The structure of the mounting portion and the counterweight in the embodiments of the present invention includes but is not limited to the above two forms.

[0090] like Figure 6As shown, the structure of the cooperation between the mounting portion 318 and the counterweight block 32 is described in detail below. The mounting portion 318 is provided with a plurality of slits 3142 arranged at intervals along the circumference of the opening 3141, and the slits 3142 are connected to the accommodating chamber 314. In the embodiment of the present invention, the plurality of slits 3142 are arranged at intervals so that the mounting portion 318 between the slits 3142 has a certain deformation space under the action of external force. For example, before the counterweight block 32 is assembled into the accommodating chamber 314 through the opening 3141, the opening 3141 is not subjected to external force in a natural state, and the maximum cross-sectional area of ​​the counterweight block 32 is larger than the size of the opening 3141 in a natural state; in the process of assembling the counterweight block 32 into the accommodating chamber 314, the counterweight block 32 is squeezed by external force against the mounting portion 318 around the opening 3141, and the mounting portion 318 is subjected to the force of the counterweight block 32 to deform. The mounting parts 318 adjacent to the slit 3142 are elastically deformed, so that the mounting parts 318 adjacent to the slit 3142 are close to each other, and the slit 3142 becomes narrower, and the opening 3141 is continuously increased to a size that allows the counterweight 32 to pass through; when the counterweight 32 is fully assembled into the accommodating cavity 314, the mounting parts 318 around the opening 3141 are not squeezed by the counterweight 32, and the mounting parts 318 restore elastic deformation, and the mounting parts 318 adjacent to the slit 3142 are separated from each other, so that the slit 3142 becomes wider, and the opening 3141 is restored to a size smaller than the maximum cross-sectional area of ​​the counterweight 32, thereby limiting the counterweight 32 from leaving the accommodating cavity 314. The embodiment of the present invention is conducive to improving the elasticity of the mounting part near the opening by arranging a plurality of slits in the circumference of the opening, thereby improving the fatigue resistance of the mounting part, and can reduce the difficulty of assembling the counterweight and the accommodating cavity, thereby improving the assembly efficiency.

[0091] In some embodiments, Figure 6 As shown, the slider 31 also includes a plurality of reinforcing ribs 319. The reinforcing ribs 319 include a first reinforcing rib 3191 and a second reinforcing rib 3192. The first reinforcing rib 3191 is arranged along the length direction of the slider 31, and the first reinforcing rib 3191 is connected to the main body 317. The first reinforcing rib 3191 can be integrally injection molded with the main body 317. By setting the first reinforcing rib, the embodiment of the present invention can improve the structural strength of the main body and reduce the material of the slider. The second reinforcing rib 3192 is arranged along the width direction of the slider 31, and the second reinforcing rib 3192 is connected to the first reinforcing rib 3191, and at least part of the second reinforcing rib 3192 is adjacent to the groove 313. Among them, the length direction of the slider indicates the direction in which the slider has the largest size, and the width direction indicates the direction perpendicular to the length. The second reinforcing rib 3192 can be integrally injection molded with the main body 317 and the first reinforcing rib 3191, and the first reinforcing rib 3191 and the second reinforcing rib 3192 can be provided in plurality. By setting the second reinforcing rib, the embodiment of the present invention can further improve the structural strength of the main body.

[0092] In some embodiments, Figure 7 As shown, the first end 311 of the slider 31 is set as a first arc surface, and the first arc surface means that the surface is a curved surface rather than a flat surface, and the curvature of the curved surface is the same or the curvature is different but the transition is smooth without an inflection point. In the case where the first end 311 contacts the drain hole 12, since the first end 311 is an arc surface, when the curvature radius of the first arc surface is equal to the curvature radius of the washing bucket, the first arc surface can form a surface contact with the wall surface around the drain hole, and when the curvature radius of the first arc surface is smaller than the curvature radius of the washing bucket, the first arc surface can form a line contact with the wall surface around the drain hole.

[0093] In some embodiments, Figure 7 As shown, a folded edge 13 is provided near the drain hole 12 of the washing bucket, and the direction in which the folded edge extends is inconsistent with the direction in which the original wall of the washing bucket extends. The folded edge 13 extends toward a side away from the washing chamber 11 relative to the wall portion of the washing bucket adjacent thereto. At the position where the first end 311 closes the drain hole 12, the first end 311 can be fitted with the folded edge 13 by setting the curvature of the surface of the folded edge 13, which can be regarded as the first end 311 being in surface contact with the drain hole 12. By making the first end 311 of the slider in surface contact with the folded edge 13 around the drain hole 12, the contact area is larger. When the movable mechanism is in the first position, it is difficult for water in the washing chamber 11 to flow out from between the first end 311 and the drain hole 12, thereby improving the sealing between the first end and the drain hole.

[0094] In some embodiments, Figure 7 As shown, the first arc surface (refer to Figure 7 The first end 311 shown in the figure is a frustum, and the diameter L4 of the frustum gradually decreases as it approaches the drain hole 12. It should be noted that the frustum does not mean that the first end 311 of the slider is in the shape of a standard frustum, but that the cross-sectional area of ​​the first end 311 of the slider (the area of ​​the cross section perpendicular to the extension direction of the slider) decreases as it approaches the drain hole 12, which is similar to the change in the cross-sectional area of ​​a frustum, so it is called a frustum. The slider in the embodiment of the present invention can be formed by injection molding. By setting the first arc surface as a frustum, it is convenient to perform mold extraction during the manufacturing process, which is beneficial to improving the processing efficiency of the slider; and the frustum fits more closely with the periphery of the convex rib, which is beneficial to improving the sealing of the clothing processing device during the washing process.

[0095] In some embodiments, Figure 7As shown, the slider 31 further includes an inner edge 315 and an outer edge 316 connected to the first arc surface, the inner edge 315 is closer to the inner wall surface 26 of the track body 2 than the outer edge 316, and the outer edge 316 is closer to the outer wall surface 25 of the track body 2 than the inner edge 315. The outer edge 316 can be smoothly connected to the inner edge 315, and the curvature of the outer edge 316 is the same as that of the inner edge 315. In the embodiment of the present invention, by setting the outer edge and the inner edge of the slider to have the same curvature, it is beneficial to manufacture the structure of the track body, so as to facilitate rapid assembly with the cavity in the track body, thereby improving the assembly efficiency.

[0096] In some embodiments, Figure 6 As shown, the second end 312 of the slider 31 is set as a second arc surface, and the second arc surface means that the surface is a curved surface rather than a flat surface, and the curvature of the curved surface is the same or the curvature is different but the transition is smooth without an inflection point. When the second end 312 is in contact with the closed end 23, the second end 312 and the closed end 23 are in point contact; for example, the surfaces of the second end 312 and the closed end 23 of the contacting slider are both curved surfaces and have different bending directions, so the contact is point contact. The embodiment of the present invention is conducive to improving the smoothness of the slider movement and reducing the risk of the slider getting stuck in the cavity by setting the closed end point of the slider in contact with the track body, so as to improve the efficiency of the slider switching between the first position and the second position.

[0097] In some embodiments, in combination Figure 1 , Figure 8 and Fig. 9 As shown, at least part of the movable mechanism 3 can roll. For example, the movable mechanism 3 can be divided into two parts, the first part can move along the cavity 22 relative to the track body 2, and the second part can not only move along the cavity 22 like the first part, but also rotate in another direction relative to the first part, so that the movable mechanism 3 can roll relative to the track body 2; then, the friction between the part of the movable structure that is in rolling contact with the track body 2 and the track body 2 is rolling friction rather than sliding friction.

[0098] For example, a part of the movable mechanism 3 can rotate relative to another part. Figure 8 As shown, the counterweight 32 is rotatably connected to the slider 31. That is to say, during the movement of the movable mechanism 3 relative to the track body, the surface of the counterweight 32 contacts the track body 2, and the friction between the counterweight 32 and the track body 2 drives the counterweight 32 to rotate relative to the slider 31, thereby realizing the rolling of the counterweight 32 relative to the track body. The embodiment of the present invention realizes rolling contact between the movable mechanism and the track body by rotatably connecting the counterweight and the slider, which is conducive to reducing the friction generated by the movement of the track body relative to the movable mechanism, thereby reducing the obstruction of the track body to the movement of the movable mechanism and improving the smoothness of the movement of the movable mechanism.

[0099] In some embodiments, Figure 8 As shown, the counterweight block 32 is set as a cylinder. The counterweight block 32 can rotate around the axis of the cylinder relative to the slider 31. The side surface 321 of the cylinder is connected to the track body 2 (combined with Figure 1 The side surface 321 of the cylinder represents the surface extending around the axis of the cylinder; the two end surfaces on the axis of the cylinder are rotatably connected to the slider 31. The cylinder and the track body can be in line contact or surface contact, and the specific contact mode is related to the diameter of the cylinder and the structure of the track body. For example, when the curvature of the side surface of the cylinder is the same as that of the track body, the cylinder can form a surface contact with the track body. When the curvature of the side surface of the cylinder is different from that of the track body, the cylinder can form a line contact with the track body.

[0100] The embodiment of the present invention arranges the counterweight block as a cylinder, thereby achieving relative rolling between the counterweight block and the track body and improving the stability of the mutual movement between the counterweight block and the track body, thereby improving the smoothness of the movement of the movable mechanism.

[0101] It should be noted that the shape of the counterweight in the embodiment of the present invention includes but is not limited to a cylinder. For example, in some embodiments, the counterweight can be set to a sphere, which represents a geometric structure in which the distance from the center to each point on the surface is equal. The counterweight can rotate around the diameter of the sphere relative to the slider, so that the surface of the sphere contacts the track body. The sphere and the track body can be in point contact, line contact, or surface contact. The specific contact mode is related to the curvature of the sphere and the structure of the track body. By setting the counterweight to a sphere, the embodiment of the present invention can reduce the friction between the track body and the counterweight while achieving relative rolling between the counterweight and the track body, which is beneficial to improving the smoothness of the movement of the movable mechanism.

[0102] In some embodiments, one or more parts of the movable mechanism can rotate relative to the slider. Fig. 9 As shown, the movable mechanism further includes a rotating body 34. The rotating body 34 is rotatably connected to the slider 31. The shape of the rotating body 34 in the embodiment of the present invention includes but is not limited to a cylinder and a sphere, as long as the rotating body 34 can rotate relative to the slider 31. Taking the rotating body 34 as a sphere as an example, the rotating body 34 can rotate around the diameter direction of the sphere relative to the slider 31. When the rotating body 34 is located in the closed drain hole 12 (combined with Figure 1The rotating body 34 may be in line contact or surface contact with the drain hole 12 at a position (as shown). The specific contact mode between the rotating body 34 and the drain hole 12 is related to the curvature of the rotating body 34, the size of the drain hole 12, and the extension angle of the structure around the drain hole 12. In the embodiment of the present invention, a rotating body that can rotate relative to the slider is provided, so that during the movement of the movable mechanism, the rotating body can roll relative to the drain hole or the surrounding of the drain hole, which is beneficial to reduce the friction between the rotating body and the drain hole and its surroundings. On the one hand, it can further improve the smoothness of the movement of the movable mechanism, and on the other hand, it can reduce the wear of the movable mechanism, thereby extending the life of the seal maintained when the movable mechanism is in contact with the drain hole.

[0103] In some embodiments, Fig. 9 As shown, when the rotating body 34 is set as a spherical body, the maximum cross-sectional area of ​​the spherical body is greater than the area of ​​the drainage hole 12, wherein the maximum cross-sectional area of ​​the spherical body is the area of ​​the cross section passing through the center of the sphere. The area of ​​the drainage hole 12 represents the area of ​​the cross section of the drainage hole 12 perpendicular to the extension direction of the drainage hole 12. The embodiment of the present invention, by limiting the relationship between the maximum cross-sectional area of ​​the spherical body and the area of ​​the drainage hole, is conducive to improving the sealing performance of the spherical body when the drainage hole is closed, thereby better saving the amount of water in the laundry processing device during the washing process.

[0104] In some embodiments, Fig. 9 As shown, the first end 311 of the slider 31 has a first groove 341 for accommodating at least part of the rotating body 34, and the parts of the slider 31 located at both ends of the first groove 341 are respectively hinged to the rotating body 34. Specifically, the first end 311 of the slider 31 is a C-shaped structure, and the slider 31 is respectively hinged to the rotating body 34 at both ends of the rotating shaft of the rotating body 34, wherein the rotating body 34 can also rotate around its own rotating shaft relative to the slider 31 while moving with the slider 31 in the cavity 22. In the embodiment of the present invention, by setting the shape of the slider, the first groove 341 can be consistent with the contour of the rotating body 34, and the first groove and the rotating body cooperate with each other, which is conducive to improving the structural compactness of the movable mechanism on the one hand, and on the other hand, it is conducive to improving the flexibility of the rotation of the rotating body.

[0105] In some embodiments, Fig. 9As shown, the second end 312 of the slider has a second groove 322 for accommodating at least part of the counterweight 32, and the parts of the slider 31 located at both ends of the second groove 322 are respectively hinged to the counterweight 32. Specifically, the second end 312 of the slider 31 is a C-shaped structure, and the slider 31 is respectively hinged to the counterweight 32 at both ends of the rotation axis of the counterweight 32, wherein the counterweight 32 can also rotate relative to the slider 31 around its own rotation axis during the movement of the slider 31 in the cavity 22. The embodiment of the present invention sets the shape of the slider so that the second groove 322 matches the contour of the counterweight 32, and the second groove cooperates with the counterweight, which is conducive to improving the structural compactness of the movable mechanism on the one hand, and on the other hand, it is conducive to improving the flexibility of the rotation of the counterweight.

[0106] In some embodiments, Figure 2 and Figure 4 As shown, the elastic member 33 abuts between the track body 2 and the slider 31. The elastic member 33 and the counterweight block 32 drive the slider 31 to move to open and close the drain hole 12. The elastic member 33 has the ability to deform and restore deformation. The elastic member 33 in the embodiment of the present invention includes but is not limited to a spring and an elastic ball. Taking the elastic member 33 as an example, the two ends of the spring are not necessarily fixedly connected to the slider 31 and the track body 2. As long as the spring abuts between the slider 31 and the track body 2, it is considered to be connected. In the embodiment of the present invention, the slider is driven to move to open and close the drain hole by the elastic member and the counterweight block. When the centrifugal force of the counterweight block is greater than the elastic force of the elastic member, the slider opens the drain hole. When the centrifugal force of the counterweight block is less than the elastic force of the elastic member, the slider closes the drain hole. The movement mode of the movable mechanism is simple, which is conducive to simplifying the drainage method of the single-barrel clothing processing device.

[0107] In some embodiments, Figure 5As shown, the slider 31 is provided with a groove 313, and the extension direction of the groove 313 can be consistent with the extension direction of the slider 31. For example, when the slider 31 is arranged along an arc direction, the groove 313 is arranged along the same arc direction. The track body 2 is provided with a first protrusion 24, and the first protrusion 24 at least partially extends into the groove 313. At least partially extending means that the first protrusion 24 can partially extend into the groove 313, and the other part is located outside the groove 313; it can also mean that the first protrusion 24 is completely extended into the groove 313. The first protrusion 24 is completely arranged in the groove 313, which is conducive to reducing the space for assembling the slider 31 and the track body 2. The opposite ends of the elastic member 33 respectively abut against the first protrusion 24 and the side of the slider 31 close to the groove 313. The length of the groove 313 is less than the natural length of the elastic member, and the distance from the first protrusion 24 to the closed end 23 is greater than or equal to the distance from the end of the groove 313 close to the closed end 23 to the closed end and less than the distance from the end of the groove 313 away from the closed end 23 to the closed end. The length direction of the groove 313 is consistent with the movement direction of the slider 31, and the minimum length of the elastic member 33 is less than the length of the groove 313. Figure 6 As shown, when the slider 31 is provided with a main body 317 and a mounting portion 318, the groove 313 runs through the main body 317, and both ends of the elastic member 33 respectively abut against the first protrusion 24 and the main body 317. In other embodiments, the length of the groove 313 is greater than the natural length of the elastic member 33, and a portion of the groove 313 is used to accommodate the elastic member 33, and the other portion is used to accommodate the first protrusion 24.

[0108] The following is a description of the assembly process of the movable mechanism 3 and the track body 2 to form the drain valve 6. First, the elastic member 33 is installed in the groove 313 of the slider 31. Since the length of the groove 313 is less than the natural length of the elastic member 33, the elastic member 33 is compressed; then, the slider 31 and the elastic member 33 are assembled with the track body 2. Specifically, the slider 31 and the elastic member 33 are placed in the track body 2 so that the first protrusion 24 abuts against the end of the elastic member 33 away from the opening 21. Thus, the assembly process between the slider 31 with the elastic member 33 abutting against one end of the groove 313 and the first protrusion 24 is completed through the above steps.

[0109] First, the slider is pushed toward the closed end 23, and the first protrusion 24 is in the groove 313, that is, Figure 4 The elastic member 33 is in the position shown in the figure, in which the elastic member 33 is compressed to the maximum extent, and the corresponding elastic force is the maximum. After the thrust for assembly is removed, since the first protrusion 24 cannot move, the elastic force of the elastic member 33 can only drive the slider 31 to move to the position of blocking the drainage hole 12, that is, Figure 2As shown in the position, since the length of the groove 313 is less than the natural length of the elastic member, the elastic member 33 still exerts an elastic force on the slider in the direction of the opening 21, thereby maintaining the slider 31 in a non-dehydration state and stably blocking the drainage hole 12.

[0110] In the dehydrated state, the centrifugal force of the weight block 32 is greater than the elastic force, thereby driving the slider 31 to move to Figure 4 The second position shown in the figure, in which the elastic member 33 is squeezed to the maximum deformation state, and the corresponding elastic force is the maximum. After the dehydration is completed, the centrifugal force of the counterweight block 32 is reduced or disappears, and the elastic member 33 exerts an elastic force on the slider 31, thereby driving the slider 31 to return to Figure 2 The first position is shown.

[0111] The embodiment of the present invention provides a groove on the slider, and the groove can limit the deformation and deformation recovery process of the elastic member. The relative movement of the groove is also limited by the first protrusion, which limits the movement trajectory of the slider relative to the track body, thereby improving the stability of the slider movement, which is beneficial to reducing the noise generated by the collision between the slider and the track body, and further improving the user experience.

[0112] In some embodiments, Figure 2 As shown, the elastic member 33 has a third end 331 and a fourth end 334 opposite to each other, the third end 331 is closer to the first end 311 of the slider 31 than the fourth end 334, the third end 331 of the elastic member 33 abuts against the slider 31, and the fourth end 334 of the elastic member 33 abuts against the first protrusion 24. In the embodiment of the present invention, by setting the extension direction of the elastic member to be consistent with the extension direction of the slider, it is beneficial to transmit the elastic force to the slider, thereby improving the reliability of the slider abutting against the drainage hole.

[0113] In some embodiments, Figure 4 As shown, the groove 313 for placing the elastic member 33 is spaced apart from the accommodating cavity 314 for accommodating the counterweight 32. The spacing means that the groove 313 and the accommodating cavity 314 have a certain distance in the extension direction of the slider 31. The embodiment of the present invention facilitates the independent assembly of the counterweight and the elastic member by separating the elastic member and the counterweight by a certain distance.

[0114] In some embodiments, Figure 4As shown, the groove 313 and the counterweight 32 are spaced apart in the length direction of the slider 31, and the groove 313 is closer to the first end 311 of the slider 31 than the counterweight 32, and the distance L1 from the groove 313 to the second end 312 is greater than the distance L2 to the first end 311. It should be noted that the groove 313 has a certain size in the extension direction, and the distance described in the embodiment of the present invention can be expressed by the distance from the center point of the groove to the first end and the second end respectively. In the embodiment of the present invention, by making the distance from the groove to the second end greater than the distance from the groove to the first end, the groove is closer to the first end relative to the second end, which is conducive to increasing the energy converted from the elastic force to the first end, thereby facilitating the reliability of the abutment between the first end of the slider and the drainage hole in a non-dehydrated state.

[0115] In some embodiments, Figure 4 As shown, the minimum distance L5 between the groove 313 and the counterweight 32 is greater than or equal to 0.25 times the length of the slider 31. The length of the slider 31 is the maximum dimension of the slider 31 in the arc direction, and can also be expressed as the length from the first end 311 to the second end 312 in the arc direction. The embodiment of the present invention limits the minimum distance between the groove and the counterweight, thereby facilitating the abutment reliability between the first end of the slider and the drainage hole in a non-dehydration state.

[0116] The specific structure of the track body 2 is described below:

[0117] In some embodiments, Figure 1 As shown, the track body 2 is provided with a stopper 24A in the cavity 22, which can be understood as the stopper 24A being provided protrudingly relative to the side of the track body 2 close to the cavity 22. The stopper 24A is used to limit the range of motion of the movable mechanism 3. For example, the stopper 24A can be a first protrusion 24 extending into the groove 313, combined with Figure 2 and Figure 4 As shown, the two ends of the elastic member 33 respectively abut against the first protrusion 24 and the slider 31. Since the track body 2 is connected to the washing tub 1 (directly or indirectly), the track body 2 is stationary relative to the washing tub 1. Regardless of whether the washing tub 1 is in a rotating or stationary state, the first protrusion 24 remains stationary relative to the washing tub 1. Then, the first protrusion 24 abuts against the elastic member 33, so that one end of the elastic member 33 is always stationary relative to the washing tub 1. The other end of the elastic member 33 is connected to the slider 31. Then, when the slider 31 moves relative to the track body 2, the slider 31 will drive the other end of the elastic member 33 to move relative to the washing tub 1. However, when the elastic member 33 is deformed to a certain extent, the elastic member 33 cannot continue to deform, thereby limiting the slider 31 from further moving relative to the track body 2. The limiter and the maximum deformation of the elastic member in the embodiment of the present invention jointly limit the movement stroke of the slider, which further limits the movement range of the movable mechanism.

[0118] In some embodiments, Figure 4 As shown, the movable mechanism 3 includes a slider 31, a counterweight 32 and an elastic member 33. The part where the first protrusion 24 abuts against the movable mechanism 3 means that the first protrusion 24 abuts against one end of the elastic member 33. Moreover, "abutting" means that one end of the elastic member 33 abuts against the surface of the first protrusion 24, and the elastic member 33 may not be connected to the first protrusion 24; of course, in some embodiments, one end of the elastic member 33 may be directly connected to the first protrusion 24, which is conducive to improving the stability of the structure of the elastic member 33.

[0119] In some embodiments, Fig.15 and Fig.16 As shown, the track body 2 includes a first cover body 27 and a second cover body 28 , and the first cover body 27 and the second cover body 28 are detachably connected.

[0120] like Figure 10-12 As shown, the first housing 27 has a first sub-cavity 221 extending along a first direction. When the cavity 22 extends along an arc direction as a whole, the first direction may be an arc direction, that is, the first sub-cavity 221 extends along an arc direction. The first protrusion 24 is located in the first sub-cavity 221.

[0121] like Figure 13-14 As shown, the second cover body 28 has a second sub-cavity 222 extending along the first direction, that is, the extension direction of the second sub-cavity 222 is consistent with the extension direction of the first sub-cavity 221. When the second cover body 28 is connected to the first cover body 27, the first sub-cavity 221 is connected to the second sub-cavity 222 and forms the cavity 22 of the track body 2. Among them, the first cover body 27 and the second cover body 28 at least partially overlap in the first direction, that is, the first cover body 27 and the second cover body 28 are respectively located on both sides of the cavity 22. It can be understood that the track body 2 can be divided into a first cover body 27 and a second cover body 28 that can be detachably connected along its length direction.

[0122] The embodiment of the present invention configures the track body as a structure in which the first cover body and the second cover body are detachably connected, so that the first cover body and the second cover body can be processed and manufactured separately, and the detachable track body reduces the difficulty of assembling the slider into the cavity, thereby facilitating improving the production efficiency of the clothing processing equipment; in addition, the detachable track body can also reduce the difficulty of repairing the movable mechanism, thereby reducing the maintenance cost of the clothing processing equipment.

[0123] In some embodiments, Fig.10As shown, the first cover body 27 includes a first top wall 271 and a first side wall 272. The first top wall 271 extends along a first direction, which is consistent with the meaning of the above embodiment, both indicating the direction of the arc, and the extension direction of the first top wall 271 in the embodiment of the present invention indicates the direction of the maximum size of the first top wall 271. The first protrusion 24 is provided on the first top wall 271, that is, the first protrusion 24 is at least partially fixedly connected to a side of the first top wall 271 close to the first sub-cavity 221.

[0124] In some embodiments, Fig.10 As shown, the first protrusion 24 includes a first extension portion 242 and a second extension portion 243. The second extension portion 243 can extend along the first direction, and the second extension portion 243 is fixedly connected to the first top wall 271. One end of the first extension portion 242 is connected to the second extension portion 243, and the other end of the first extension portion 242 is a free end. The first extension portion 242 is arranged to protrude relative to the first top wall 271. When the track body and the slider are assembled as one, the first extension portion 242 extends into the groove of the slider, and the first extension portion 242 abuts against one end of the elastic member. In some embodiments, the first protrusion 24 also includes an elastic limiting column 241. The elastic limiting column 241 can extend along the first direction, and the elastic limiting column 241 can also extend approximately along a straight line direction tangent to a certain position in the first direction. One end of the elastic limiting column 241 is connected to one end of the first extension portion 242 away from the second extension portion 243, and the other end of the elastic limiting column 241 is a free end. When the track body 2 and the movable mechanism 3 are assembled as one, the elastic part can be sleeved around the elastic limiting column 241. For example, the elastic part is set as a spring, and the spring is sleeved on the outside of the elastic limiting column 241. The elastic limiting column can support and guide the elastic part. The elastic part can move along the extension direction of the elastic limiting column, which is beneficial to improve the stability of the movement of the elastic part, thereby improving the reliability of the movement of the movable mechanism.

[0125] In some embodiments, Fig.10 As shown, the first side wall 272 is arranged around the edge of the first top wall 271, and the first side wall 272 and the first top wall 271 form a first sub-cavity 221 with at least one end open, and the open end can be opposite to the first top wall 271. The first side wall 272 is arranged along an arc line, which means that the extension direction of the first side wall 272 is related to the peripheral extension direction of the first top wall 271, and the first side wall 272 is roughly a circular arc wall surface, which is beneficial to reduce the friction force generated by the contact between the slider and the first side wall 272, thereby improving the smoothness of the movement of the movable mechanism. Among them, the first sub-cavity 221 forms a first opening 211 at one end in the first direction. Specifically, the first sub-cavity 221 has two opposite ends in the first direction, and one end is provided with a first opening 211 connected to the first sub-cavity 221. When the movable mechanism moves, the slider can pass through the first opening 211. As shown Fig.15As shown, the first side wall 272 is detachably connected to the second cover body 28 .

[0126] In the embodiment of the present invention, the first side wall is arranged around the edge of the first top wall to form a first sub-cavity, and the first side wall is detachably connected to the second cover body, which helps to reduce the difficulty of assembling the first cover body and the second cover body, thereby improving the production efficiency of the clothing processing equipment.

[0127] In some embodiments, Fig.10 As shown, the ratio of the distance from the first protrusion 24 to the first opening 211 in the first direction to the length of the first sub-cavity 221 in the first direction is less than or equal to 0.3. In the embodiment of the present invention, by limiting the maximum value of the distance from the first protrusion to the first opening, the first protrusion is close to the first opening, thereby limiting the position of the elastic member close to the opening, which is conducive to reducing the moment of the elastic member in the groove acting on the first end, thereby facilitating the abutment reliability between the first end of the slider and the drainage hole in the non-dehydration state.

[0128] In some embodiments, Fig.13 As shown, the second cover body 28 includes a second top wall 281 and a second side wall 282. The second top wall 281 extends along the first direction, that is, the second top wall 281 extends along the arc direction. The second side wall 282 is arranged around the edge of the second top wall 281, and the second side wall 282 and the second top wall 281 form a second sub-cavity 222 with at least one end open, and the open end can be opposite to the second top wall 281. The second side wall 282 is arranged along the arc line, which means that the extension direction of the second side wall 282 is related to the peripheral extension direction of the second top wall 281, and the second side wall 282 is roughly a circular arc wall surface, which is conducive to reducing the friction generated by the contact between the slider and the second side wall 282, thereby improving the smoothness of the movement of the movable mechanism. Among them, the second sub-cavity 222 forms a second opening 212 at one end in the first direction. Specifically, the second sub-cavity 222 has two opposite ends in the first direction, and the two ends in the first direction represent that the connecting line of the two ends extends along the first direction. One end of the second sub-cavity 222 is provided with a second opening 212 connected to the second sub-cavity 222, and when the movable mechanism moves, the slider can pass through the second opening 212. Fig.15 As shown, the first side wall 272 is detachably connected to the second side wall 282, and the first opening 211 and the second opening 212 together form the opening 21 of the track body. The slider can pass through the opening 21 during the movement of the slider to open and close the drain hole.

[0129] In the embodiment of the present invention, the second side wall is arranged around the edge of the second top wall to form a second sub-cavity, and the second side wall is detachably connected to the first side wall, which helps to reduce the difficulty of assembling the first cover body and the second cover body, thereby improving the production efficiency of the clothing processing equipment.

[0130] In some embodiments, Fig.11 As shown, the first side wall 272 includes a first outer wall 2721 and a first inner wall 2722. The first outer wall 2721 and the first inner wall 2722 are respectively located on both sides of the first sub-cavity 221. Since the first sub-cavity 221 extends along the first direction, it can be understood that the first outer wall 2721 and the first inner wall 2722 are respectively located on both sides of the first direction. The two sides of the first direction represent that the line connecting the first outer wall 2721 and the first inner wall 2722 intersects with the first direction. In the embodiment of the present invention, the first outer wall 2721 and the first inner wall 2722 can be smoothly connected, so there can be no obvious boundary between the first outer wall 2721 and the first inner wall 2722. It can be understood that the embodiment of the present invention divides the first side wall 272 into two parts located on both sides of the second direction by distinguishing the first outer wall 2721 and the first inner wall 2722.

[0131] like Fig.13 As shown, the second side wall 282 includes a second outer wall 2821 and a second inner wall 2822. The second outer wall 2821 and the second inner wall 2822 are respectively located on both sides of the second sub-cavity 222. Since the second sub-cavity 222 extends along the first direction, it can be understood that the second outer wall 2821 and the second inner wall 2822 are respectively located on both sides of the first direction. The two sides of the first direction represent that the line connecting the second outer wall 2821 and the second inner wall 2822 intersects with the first direction. In the embodiment of the present invention, the second outer wall 2821 and the second inner wall 2822 can be smoothly connected, so there can be no obvious boundary between the second outer wall 2821 and the second inner wall 2822. It can be understood that the embodiment of the present invention divides the second side wall 282 into two parts located on both sides of the second direction by distinguishing the second outer wall 2821 and the second inner wall 2822.

[0132] In the embodiment of the present invention, combined with Fig.11 and Fig.13As shown, corresponding clamping members 29 are provided on the first outer wall 2721 and the second outer wall 2821. The clamping members 29 represent that they can be mutually clamped and limited to play a role of connection. In the embodiment of the present invention, a plurality of clamping members can be provided on the first outer wall 2721, and a plurality of corresponding clamping members can be provided on the second outer wall 2821. The plurality of clamping members 29 on the first outer wall 2721 and the plurality of corresponding clamping members 29 on the second outer wall 2821 are connected one by one, thereby realizing the connection between the first outer wall 2721 and the second outer wall 2821. In some embodiments, the clamping members 29 can also be provided on the first inner wall 2722 and the second inner wall 2822. In the embodiment of the present invention, a plurality of clamping members 29 can be provided, and the clamping members 29 can be provided at various positions of the track body. By increasing the number of the clamping members 29 provided, it is beneficial to improve the stability of the connection between the first cover body and the second cover body. The embodiment of the present invention connects the first cover body and the second cover body by providing a clamping piece, thereby achieving a detachable connection between the first cover body and the second cover body, which has a simple structure and is easy to install, and is conducive to reducing the production cost of the clothing processing equipment.

[0133] In some embodiments, Fig.11 As shown, the first inner wall 2722 includes a first boss 2723. The first inner wall 2722 can be understood as a thin-walled part, so the first boss 2723 can be understood as a protruding structure with a certain thickness, and the first boss 2723 can protrude from the side of the first inner wall 2722 in the first direction (the meaning of the side in the first direction can refer to the description of the aforementioned embodiment). The first boss 2723 has two opposite surfaces, one of which is close to the first top wall 271 and the other is away from the first top wall 271. The surface of the first boss 2723 away from the first top wall 271 is defined as the first surface 2724. The clamping member 29 can be arranged on the first surface 2724. In the embodiment of the present invention, the clamping member is arranged on the first surface by arranging the first protrusion and the first surface located on the first protrusion. The area of ​​the first surface is relatively large relative to the first inner wall. On the one hand, it can reduce the difficulty of processing the clamping member, and on the other hand, it can reduce the interference of the clamping member on the movement of the slider in the first sub-cavity.

The third boss 2725 has two opposite surfaces, one of which is close to the first top wall 271, and the surface away from the first top wall 271 is defined as the third surface 2726. In the embodiment of the present invention, a positioning member 7 is provided on the third surface 2726.

[0137] like Fig.13As shown, the second outer wall 2821 includes a fourth boss 2825 that is protruded outward. In the embodiment of the present invention, the side of the second outer wall 2821 close to the second sub-cavity 222 is defined as the inner side, and the side of the second outer wall 2821 away from the second sub-cavity 222 is defined as the outer side, so the fourth boss 2825 is protruded relative to the second outer wall 2821 toward the side away from the second sub-cavity 222. The fourth boss 2825 has two opposite surfaces, one of which is close to the second top wall 281, and the surface away from the second top wall 281 is defined as the fourth surface 2826. In the embodiment of the present invention, a corresponding positioning member 7 is provided on the fourth surface 2826.

[0138] Combination Fig.11 and Fig.13 As shown, the positioning piece 7 on the third surface 2726 can cooperate with the corresponding positioning piece 7 on the fourth surface, so as to play a positioning role. During the assembly process of the first cover body and the second cover body, the positioning pieces located on the third surface and the fourth surface can be pre-matched and aligned, so that the first cover body and the second cover body can be quickly aligned during the assembly process, reducing the risk of misalignment during the assembly process of the first cover body and the second cover body, which is conducive to improving the efficiency of assembling the first cover body and the second cover body.

[0140] In some embodiments, in combination Fig.11 and Fig.13 As shown, the clamping member 29 includes a protruding claw 291 and a slot 292. The claw 291 is detachably connected to the slot 292. It should be noted that the clamping member 29 on the first cover 27 can be set as the claw 291, and the corresponding clamping member 29 on the second cover 28 can be set as the slot 292. Alternatively, the clamping member 29 on the first cover 27 is set as the slot 292, and the corresponding clamping member 29 on the second cover 28 is set as the claw 291.

The first side wall 272 is provided with a first abutting surface 2921 near the slot 292, and the first abutting surface 2921 is parallel to the first top wall 271. Fig.13 As shown, one end of the claw 291 is connected to the second side wall 282, and the other end of the claw 291 is a free end. The free end of the claw 291 is provided with a structure protruding toward the second sub-cavity 222, and the free end has a second abutting surface 2911. Fig.14 As shown, the second abutting surface 2911 is parallel to the second top wall 281. Fig.15 and Fig.16 As shown, when the first cover body 27 is connected to the second cover body 28, the claw 291 is connected to the slot 292, that is, the first abutting surface 2921 abuts against the second abutting surface 2911, thereby limiting the movement of the claw 291 relative to the slot 292, and the connection between the first cover body 27 and the second cover body 28 is achieved by the limiting of the claw 291 and the slot 292.

[0142] It should be noted that the embodiment of the present invention only illustrates one of the configuration methods of the clamping member. In other embodiments, the clamping claw may be disposed on the first cover body and the clamping slot may be disposed on the second cover body. The principle of the connection is consistent with the above embodiment, so it will not be described in detail. In addition, the specific structure of the connection between the clamping claw and the clamping slot in the embodiment of the present invention includes but is not limited to the above embodiments.

[0143] The embodiment of the present invention can limit the relative position of the first cover body and the second cover body by configuring the clamping member as a structure of a clamping claw and a clamping groove. The structure is simple and the installation is convenient, which is beneficial to improving the assembly efficiency of the first cover body and the second cover body.

[0144] In some embodiments, in combination Fig.11 and Fig.13 As shown, the positioning member 7 includes a positioning shaft 71 and a blind hole 72. The positioning shaft 71 is configured as a protruding structure, and the blind hole 72 is configured as a recessed structure. The positioning shaft 71 can be inserted into the blind hole 72 to achieve alignment and limiting of the first cover body and the second cover body. It should be noted that the blind hole 72 indicates that one end of the hole is open in the extension direction and the other end is closed, and the positioning shaft 71 can extend from the open end of the blind hole 72 into the blind hole 72.

Alternatively, the positioning member 7 on the first cover body 27 is configured as a blind hole 72, and the corresponding positioning member 7 on the second cover body 28 is configured as the positioning shaft 71. Combined with Fig.11 and Fig.13 As shown, the assembly of the track body is described by taking the positioning member 7 on the first cover body 27 as a positioning shaft 71 and the positioning member 7 on the second cover body 28 as a blind hole 72 as an example:

[0145] like Fig.11 As shown, the positioning shaft 71 can be disposed on the first boss 2723, one end of the positioning shaft 71 is connected to the first surface 2724, and the extending direction of the positioning shaft 71 is perpendicular to the first surface 2724.

[0146] like Fig.13 As shown, the blind hole 72 is disposed on the second boss 2823, and the blind hole 72 passes through the second surface 2824. The blind hole 72 can also be disposed on the fourth boss 2825. Specifically, the fourth boss 2825 also includes a cylindrical structure, one end of which forms a fourth surface 2826, and the blind hole 72 passes through the fourth surface 2826.

[0147] Combination Fig.11 and Fig.13 As shown, during the assembly process of the first cover body 27 and the second cover body 28, the positioning shaft 71 located on the first boss 2723 can extend into the blind hole 72 on the second boss 2823, and the positioning shaft 71 located on the third boss 2725 can extend into the blind hole 72 on the fourth boss 2825.

[0148] The embodiment of the present invention increases the number of structures for aligning the first cover body with the second cover body by respectively setting corresponding positioning shafts and blind holes on the first boss and the second boss, and setting corresponding positioning shafts and blind holes on the third boss and the fourth boss, which is beneficial to improving the alignment accuracy of the first cover body with the second cover body, thereby improving the quality of track body assembly.

[0149] In some embodiments, Fig.10 and Fig.12 As shown, the first top wall 271 is provided with a first through hole 273 connected to the first sub-cavity 221, so that the liquid in the washing bucket can flow into the first sub-cavity 221 through the first through hole 273.

A plurality of first through holes 273 may be provided on the first top wall 271, and the plurality of first through holes 273 may be arranged at intervals on the first top wall 271, so that the first top wall can not only limit and protect the slider, but also improve the water flow efficiency.

[0150] like Fig.13 and 14As shown, the second top wall 281 is provided with a second through hole 283 connected to the second sub-cavity 222, so that the liquid in the washing bucket can flow into the second sub-cavity 222 through the second through hole 283.

[0151] The following is an explanation of the indirect connection between the track body 2 and the washing tub 1:

[0152] In some embodiments, Fig.17 As shown, the clothing processing device includes a washing tub 1, a lifting rib 5 and a drain valve 6. A washing chamber 11 and a drain hole 12 connected to the washing chamber 11 are provided in the washing tub 1, the lifting rib 5 is arranged in the washing chamber 11 and connected to the washing tub 1, and a mounting chamber 51 connected to the washing chamber is provided in the lifting rib 5. The drain valve 6 in the embodiment of the present invention is indirectly connected to the washing tub 1 through the lifting rib 5. The indirect connection means that the drain valve 6 can at least partially be stationary relative to the lifting rib 5 and the washing tub 1. Specifically, the drain valve 6 is arranged in the mounting chamber 51, and the drain valve 6 can at least partially move relative to the mounting chamber 51, so as to realize the closing and opening of the drain hole 12. It should be noted that the drain valve 6 in the embodiment of the present invention includes the drain valve structure described in any of the above embodiments, which includes a track body 2 and a movable mechanism 3.

[0153] It should be noted that the lifting ribs 5 are structures that are raised relative to the inner wall surface of the washing tub 1. The lifting ribs 5 are used to generate friction with the clothes in the washing chamber 11. The part of the clothes close to the lifting ribs 5 and the part away from the lifting ribs 5 rub against each other to produce a rubbing effect; in addition, the lifting ribs can drive the clothes to rotate together, and the clothes are lifted out of the liquid surface and sent to a certain height. The clothes fall back into the washing liquid due to gravity, and the collision of the clothes with the liquid produces a beating and falling effect, thereby improving the cleaning degree of the clothes.

[0154] The embodiment of the present invention arranges the drain valve in the lifting ribs, which can improve the cleanliness of the clothes in the washing chamber. The lifting ribs can also protect the drain valve and reduce the interference of the rotation of the clothes in the washing chamber on the drain valve. In addition, the drainage valve is arranged in the lifting ribs to reduce the volume occupied by the components in the washing barrel, which can improve the compactness of the structure of the clothing processing equipment and is beneficial to increase the volume ratio of the washing chamber when the size of the washing barrel is constant.

[0155] In some embodiments, Fig.18 As shown, the drain valve 6 is provided with a limit portion, and the limit portion limits the circumferential movement of the drain valve 6 relative to the lifting rib 5 in the washing tub 1. In some embodiments, as Fig.18 As shown, the limiting portion is provided with a first connection portion 61, and the lifting rib 5 is provided with a second connection portion 62. The first connection portion 61 and the second connection portion 62 cooperate to limit the circumferential movement of the drain valve 6 relative to the lifting rib 5 in the washing tub 1. The circumferential direction of the washing tub 1 refers to the direction of rotation around the axial direction of the washing tub 1. Of course, in some embodiments, the first connection portion 61 and the second connection portion 62 cooperate to limit the radial movement of the drain valve 6 relative to the lifting rib 5 in the washing tub 1. The radial direction of the washing tub 1 refers to the direction of any straight line perpendicular to the axial direction of the washing tub 1.

[0156] The specific configuration of the first connection portion 61 and the second connection portion 62 is described below by way of example:

[0157] Combination Figure 18-Figure 20 As shown, the first connection portion 61 can be set as a protrusion, and the second connection portion 62 can be set as a groove. Among them, the protrusion structure of the first connection portion 61 is formed on the surface of the drain valve 6 alone, and can also be formed by the existing structure on the surface of the track body 2, for example, combined with Fig.15 As shown, the first cover body 27 and the second cover body 28 are connected to each other through the positioning shaft and the blind hole formed between the third boss and the fourth boss. Then the matched third boss and the fourth boss can jointly form a first connecting portion 61 for matching with the lifting rib.

[0158] The embodiment of the present invention forms a first connecting portion by means of a third boss and a fourth boss, which can not only meet the alignment and cooperation between the first cover body and the second cover body, but also achieve the cooperation and limitation with the lifting rib, which is beneficial to simplify the structure of the connection between the lifting rib and the drain valve and improve the space utilization rate of the clothing processing equipment.

[0159] It should be noted that the first connection part can also be set as a groove, and the corresponding second connection part can be set as a protrusion. When the drain valve and the lifting rib are matched, the second connection part is inserted into the first connection part. The principle of this matching is consistent with the above embodiment, so it will not be repeated.

[0160] In some embodiments, Fig.21 and Fig. 22 As shown, Fig.21 This is a bottom stereogram of the lifting rib. Fig. 22 The cross-sectional diagram of the connection between the lifting rib and the drain valve is shown. Fig. 22 As shown, the drain valve 6 is provided with a fifth surface 63, and the lifting rib 5 is provided with a sixth surface 64. The fifth surface 63 and the sixth surface 64 are both in contact with the axial direction ( Fig. 22 When the lifting rib is connected to the drain valve, the fifth surface 63 abuts against the sixth surface 64, thereby limiting the radial movement of the drain valve 6 relative to the lifting rib 5 in the washing tub 1. It should be noted that the radial direction of the washing tub 1 represents Fig. 22 The direction of any straight line parallel to the paper plane passing through the axis of the washing tub is Fig. 22 The fifth surface and the sixth surface are both perpendicular to the radial direction.

[0161] The embodiment of the present invention arranges a fifth surface on the drain valve and a sixth surface on the lifting rib, and through the mutual abutment between the fifth surface and the sixth surface, the lifting rib and the drain valve are limited in the radial direction of the washing barrel, thereby improving the stability of the connection between the drain valve and the lifting rib, which is beneficial to reducing the noise of the operation of the clothing processing equipment.

[0162] In some embodiments, Fig. 22 As shown, the cross section of the lifting rib 5 can be set to a conical structure, that is, the width of the lifting rib 5 is from one end close to the inner wall of the washing tub ( Fig. 22 The width of the washing tub is shown in the figure. Fig. 22 The embodiment of the present invention sets the lifting rib as a conical structure, and the width of the connection between the lifting rib and the washing bucket is relatively large, which is conducive to improving the strength of the connection between the lifting rib and the washing bucket; on the other hand, the width of the lifting rib on the side away from the washing bucket is relatively narrow, which can limit one end of the drain valve. Through the conical structure of the lifting rib and the abutment of the fifth surface and the sixth surface, the drain valve can be limited in two opposite directions. For example, the fifth surface and the sixth surface can limit the drain valve relative to the lifting rib. Fig. 22 The cone-shaped structure of the lifting rib can limit the downward movement of the drain valve relative to the lifting rib. Fig. 22 The upward movement shown in the figure realizes the limitation of the relative directions of the upper and lower directions, thereby improving the stability of the position between the lifting rib and the drain valve.

[0163] In some embodiments, in combination Fig.21 and Fig. 22 As shown, a clamping member 52 extending in the radial direction is provided in the lifting rib 5, and the radial direction is the diameter direction of the washing tub. In the implementation of the present invention, the height direction of the lifting rib 5 is consistent with the radial direction, and can be used Fig. 22 The vertical direction in the figure indicates the height direction of the lifting rib 5. One end of the clamping member 52 ( Fig. 22 The upper end shown in the figure) is connected to the inner wall surface of the lifting rib 5, and the other end of the clamping member 52 ( Fig. 22 The other end (shown at the lower end) of the clip 52 is provided with a sixth surface 64. Fig. 22 The lower end shown in the figure) can be set in the width direction of the lifting rib ( Fig. 22 The structure protrudes in the left and right directions as shown. Fig. 22The assembly process of the drain valve 6 and the lifting rib 5 is described. The drain valve 6 can be installed from the bottom of the lifting rib 5 from bottom to top. When the drain valve 6 contacts the free end of the clamping member 52, the drain valve 6 pushes the free end of the clamping member 52 to deform outward. When the upper end of the drain valve 6 is limited by the upper part of the lifting rib 5, the free end of the clamping member 52 recovers the elastic deformation, so that the fifth surface 63 is in contact with the sixth surface 64, and one side of the clamping member 52 ( Fig. 22 The side surfaces in the left and right directions shown in the figure abut against the side surfaces of the drain valve 6, thereby limiting the movement of the drain valve and the lifting rib in the width direction.

[0164] In some embodiments, Fig. 22 As shown, the clips 52 can be arranged in pairs, and a pair includes two clips 52. The two clips 52 are respectively arranged to be spaced apart in the width direction of the lifting rib 5. The two clips 52 are relatively arranged to limit the two sides of the drain valve in the width direction, which is beneficial to improve the stability of the connection between the drain valve and the lifting rib.

[0165] In some embodiments, Fig. 22 As shown, the distance L6 between the fifth surface 63 and the bottom surface of the track body 2 is less than or equal to 0.5 times the maximum dimension L7 of the track body 2 in the radial direction of the washing tub 1. The embodiment of the present invention limits the positional relationship between the fifth surface and the track body, that is, the fifth surface is arranged close to the bottom surface of the track body, which is conducive to reducing the difficulty of assembling the lifting rib and the drain valve, and can also improve the compactness of the assembly.

[0166] In some embodiments, Fig.17 As shown, a plurality of lifting ribs 5 are provided in the washing tub 1, and the plurality of lifting ribs 5 are arranged at intervals in the circumferential direction of the washing tub 1, and the circumferential direction of the washing tub 1 is the direction around the axial direction of the washing tub 1. The embodiment of the present invention is conducive to improving the degree of cleaning of clothes by the clothes processing device by providing a plurality of lifting ribs.

[0167] In some embodiments, Fig.17 As shown, there are multiple drain holes 12, and multiple drain valves 6 are arranged in the same installation cavity 51. The multiple drain valves 6 are arranged at intervals along the axial direction of the washing tub 1. The embodiment of the present invention is beneficial to improving the drainage efficiency of the washing tub by arranging multiple drain valves and multiple drain holes in one lifting rib.

[0168] In some embodiments, Fig. 20 As shown, the lifting rib 5 is axially ( Fig. 20 The lifting ribs 5 extend in the left and right directions as shown, and a plurality of convex ribs 53 are provided on the lifting ribs 5 to lift the clothes and increase the friction with the clothes. The embodiment of the present invention also provides a control method of a clothes processing device according to any of the above items, combined with Figure 1-4 and Fig.23As shown, the control method includes:

[0169] S1. Control the washing tub 1 to rotate at a speed less than the first value so that the movable mechanism 3 closes the drain hole 12. It should be noted that the first value can be zero, that is, whether the washing tub is in a non-working state or in a low-speed rotation state for washing, the centrifugal force generated by the washing tub on the movable mechanism is small, and the movable mechanism remains in the first position of closing the drain hole, which is conducive to the accumulation of water in the washing chamber, and can wash clothes while saving water.

[0170] S2. Control the washing tub 1 to rotate at a speed greater than or equal to the first value so that the movable mechanism 3 opens the drain hole 12. When the speed of the washing tub 1 is greater than or equal to the first value, the centrifugal force generated by the washing tub 1 on the movable mechanism 3 can drive the movable mechanism 3 to rotate relative to the track body 2, and the movable mechanism rotates from the first position to the second position of opening the drain hole 12. The water in the washing chamber 11 can flow to the drain hole 12 to be discharged to the outside of the clothing processing device, thereby achieving dehydration of the clothing. The control method of the clothing processing device provided by the embodiment of the present invention can control the opening and closing of the drain hole by controlling the speed of the washing tub. The control method is simple and is conducive to improving the efficiency of clothing washing.
