An embodiment of the present application provides a clothes processing equipment, which may be a washing machine, a washing and drying machine, etc. It should be noted that the application scenario types of the embodiments of the present application do not limit the clothing processing equipment of the embodiments of the present application.

The following description takes the clothes processing equipment as a washing machine as an example. Figure 1 shows a schematic cross-sectional view of the washing machine in a washing state, and the cross-section is a cross-section perpendicular to the rotating axis of the washing machine. The clothes processing equipment provided by the embodiment of the present application includes a washing tub 1 and a drain valve 6 . The arrow in Figure 4 shows the circumferential direction of the washing tub.

As shown in Figure 1, the washing tub 1 has a washing chamber 11 inside. The washing chamber 11 can be used to accommodate clothes to be processed. The steps of clothes processing equipment include but are not limited to soaking, washing and dehydration. The washing tub 1 is provided with a drainage hole 12 that communicates with the washing chamber 11 . The drainage hole 12 communicates with the washing chamber 11 and the outside of the washing chamber 11 . It should be noted that the clothes processing equipment in the embodiment of the present application can be a single-tub washing machine or a double-tub washing machine. For example, when the clothes processing equipment is set as a single-tub washing machine, the drainage hole 12 can communicate with the washing chamber 11 and the washing machine. When the drainage hole 12 is opened, the water in the washing chamber 11 can be directly discharged to the outside of the clothing processing equipment through the drainage hole 12 . Of course, the casing of the clothes processing equipment located outside the washing tub 1 can also be provided with a water receiving tray. A water collecting cavity is formed between the water receiving pan and the washing tub. The drainage hole 12 can connect the washing cavity and the water collecting cavity. When the equipment is in the dehydrating state, the drainage hole 12 is opened, and the drainage hole 12 guides the water in the washing chamber 11 to the water collecting chamber, and the water collecting tray guides the water in the water collecting chamber to the outside of the clothes processing equipment. When the clothes treatment equipment is configured as a double-tub washing machine, the clothes treatment equipment includes a washing tub 1 and a housing 4. The gap between the housing 4 and the washing tub 1 can form a water collecting cavity, and the water collecting cavity and the drainage hole 12 In addition to being connected to the water collection cavity through the drainage hole 12, the other parts of the washing tub 1 are closed relative to the water collection cavity. That is to say, the water in the washing cavity 11 can only be led out from the drainage hole 12 to the water collection cavity. into the chamber, and then guide the water in the water collecting chamber to the outside of the clothes treatment equipment. It should be noted that, regardless of whether the clothes processing equipment in the embodiment of the present application is a single-tub washing machine or a double-tub washing machine, the drainage hole in the embodiment of the present application can be directly or indirectly connected to the outside of the clothes processing equipment to connect the washing cavity 11 The water inside is directed to the outside of the laundry treatment device.

As shown in FIG. 1 , the drain valve 6 includes a track body 2 and a movable mechanism 3 . The track body 2 is disposed in the washing chamber 11 and is directly or indirectly connected to the washing tub 1. The following content will specifically describe the implementation of direct connection and indirect connection. Among them, the track body 2 defines a movement channel, and the movable mechanism 3 can move in an arc along the movement channel to close and open the drainage hole. When the movable mechanism 3 closes the drainage hole 12, it means that the movable mechanism 3 can completely cover the drainage hole 12, so that the liquid in the washing cavity 11 cannot flow out from the drainage hole 12 to the outside of the washing tub 1; when the movable mechanism 3 opens the drainage hole 12, it means The movable mechanism 3 is spaced apart from the drainage hole 12 so that the liquid in the washing cavity 11 can flow out from the drainage hole 12 to the outside of the washing tub 1 . Among them, there are many ways to structure the track body 2 and define the movement channel. The movement channel can be formed in an open space or in a closed space. The following methods will be enumerated to illustrate several modes of motion channels. However, those skilled in the art can understand that the embodiments of the present application are not limited to the following modes. Other motion channels can be defined by the track body, so that the movable mechanism can move along its arc. Any shape movement is possible.

In addition, the arc-shaped movement of the movable mechanism is used to illustrate that the trajectory of the movable mechanism is arc-shaped. It can be understood that the arc-shaped movement trajectory of the movable mechanism does not limit the relative movement between various parts or components of the movable mechanism. As long as the movement is The movement trajectory of the entire mechanism, such as its outline, basically exhibits arc motion that is different from linear motion. Among them, the radius of curvature of the arc can be a single 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 straight trajectory.

In the embodiment of the present application, the track body is provided with a movement channel, and the movable mechanism can open and close the drainage holes along the arc-shaped movement of the movement channel. On the one hand, the movable mechanism can open and close the drainage holes through movement, making the drainage method simpler; on the other hand, The movement of the movable mechanism is arc-shaped, and the length of the movement trajectory is longer. Compared with the structure without a designed track body, the movable mechanism consumes more kinetic energy during the movement. Therefore, when the movable mechanism moves to the position of closing the drainage hole, the movable mechanism The impact energy on the wall of the washing tub is smaller, so the noise produced is smaller. The embodiments of the present application can simplify the drainage method of the clothes processing equipment while making less noise, which is beneficial to reducing costs and improving user experience.

In some embodiments, the movement channel includes a support surface, the support surface is formed in an arc shape, and the arc-shaped opening of the support surface faces the side wall of the washing tub. It can be understood that the supporting surface can be a plane or a curved surface, and its overall extension direction is arc-shaped. For example, a line segment can be rotated at a certain angle with a point other than the line segment as the center of the circle to form an arc-shaped supporting 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 arranging 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 It protrudes toward the axis of the rotation axis of the washing tub and forms an inward convex shape, so that when the washing tub rotates around the above-mentioned axis, the movable mechanism 3 moves along the support surface to open and close the drainage hole along with the rotation of the washing tub. In the embodiment of the present application, the support surface is arranged in an arc shape, which is beneficial to guiding the arc-shaped movement of the movable mechanism and reducing the impact on the movable mechanism during the arc-shaped movement, thereby helping to reduce the noise generated by the movement of the movable mechanism.

In some embodiments, the track body 2 is arc-shaped. It can be understood that the overall outline 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. 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 its length direction, which is the direction of the arc from one end to the other end. In this embodiment, the extension direction of the arc-shaped track body is along the axial direction of the washing tub, which can reduce the requirements for installing the cavity of the movable mechanism. For example, the movable mechanism and the track body can be arranged in the lifting rib, and the edge of the lifting rib can be fully utilized. The longer length of the washing tub in the axial direction.

Among them, the movable mechanism 3 is suitable for sliding and/or rolling along the supporting surface. It can be understood that the movable mechanism 3 can perform translation relative to the support surface along the support surface, that is, slide along the support surface; it can also perform both translation and rotation relative to the support surface, as long as the overall movement trajectory of the movable mechanism 3 is arc-shaped. Can. By setting the movable mechanism to slide and/or roll, the embodiments of the present application are conducive to improving the diversity of implementation methods of the movable mechanism, and when the movable mechanism can at least partially roll, it can It can reduce the friction between the movable mechanism and the supporting surface and improve the smoothness of the movement process of the movable mechanism.

In some embodiments, the side of the movable mechanism 3 facing the support surface is provided with an arc-shaped structure adapted to the support surface, and the arc-shaped structure is suitable for sliding along the support surface. It can be understood that the arc-shaped structure on the movable mechanism 3 can be formed in a variety of ways. For example, the arc-shaped structure can be an arc-shaped surface or a plurality of convex ribs extending in an arc shape, with intervals between each convex rib. Space, etc., as long as the outline of the side of the movable mechanism 3 facing the support surface is arc-shaped, and the arc-shaped structure is in contact with the arc-shaped support surface and is suitable for sliding along the support surface. Then, the arc-shaped structure is slidable relative to the support surface, and other parts of the movable mechanism 3 can be fixedly or rotatably connected to the arc-shaped structure, so that the movable mechanism 3 can slide or at least partially roll along the support surface. In the embodiment of the present application, an arc-shaped structure adapted to the support surface is provided on the movable mechanism, thereby improving the smoothness of the movement of the movable mechanism along the support surface and reducing friction during the relative movement between the movable mechanism and the support surface.

The following is an illustrative description of the specific way in which the track body forms a supporting surface: in the first way, the track body 2 itself can be similar to a flat part or a curved surface part, and can be approximately regarded as a two-dimensional component. There is no void formed inside the track body 2. Cavity, all or most of the surface of the track body 2 forms a supporting surface. In the second way, the track body 2 is a three-dimensional component with a cavity inside. A part of the surface of the track body 2 forms a support surface. The cavity can be open on one side of the support surface, that is, the opening is connected to the support surface. Adjacent, the opening may be opposite to the supporting surface, or the opening may include multiple directions, both adjacent to and opposite to the supporting surface.

The following description takes the cavity 22 in the track body 2 as an example. As shown in Figures 1 to 4, the movable mechanism 3 can move along the cavity 22 to close and open the drainage hole 12,

In the embodiment of the present application, there are two ways of connecting the drain valve 6 to the washing tub 1. In one embodiment, as shown in Figure 1, the rail body 2 is directly connected to the washing tub 1, and the rail body 2 is arranged in the washing cavity. Within 11. In another embodiment, as shown in Figure 17, the washing tub 1 is provided with lifting ribs 5 for lifting the height of the clothes. The lifting ribs 5 are hollow inside, and the drain valve 6 is arranged in the lifting ribs 5. The drain valve 6 is connected to the lifting ribs 5. The ribs 5 are connected to achieve an indirect connection with the washing tub 1.

The following describes the direct connection method between the drain valve 6 and the washing tub 1:

As shown in FIG. 1 , the track body 2 is arranged in the washing cavity 11 , and the track body 2 is directly connected to the washing tub 1 . The rail body 2 in the embodiment of the present application can be detachably connected to the washing tub 1 through a snap-in structure, and the rail body 2 can also be permanently fixed to the washing tub 1 through welding. No matter what connection method is used between the track body 2 and the washing tub 1, as long as the track body 2 can remain stationary relative to the washing tub 1 during the process of clothes processing. The washing tub 1 in the embodiment of the present application can be roughly configured as a cylindrical structure. The washing tub 1 includes a bottom wall and side walls arranged around the edge of the bottom wall. The side walls are arranged around the axial direction of the washing tub 1 . The embodiment of the present application does not limit the specific connection position between the rail body 2 and the washing tub 1. For example, the rail body 2 can be disposed at any position on the side wall of the washing tub.

As shown in Figure 1-4, the cavity 22 in the track body 2 is connected with the washing cavity 11. The liquid in the washing cavity 11 can flow to the drainage hole 12 through the cavity 22, or the liquid in the washing cavity 11 does not need to pass through the cavity 22. The cavity 22 is discharged directly from the drainage hole 12 .

With reference to Figures 2 and 4, the path of liquid flow in the washing chamber 11 is explained:

One end of the cavity 22 forms an opening 21 (the right end of the track body 2 shown in Figures 2 and 4), and the other end is a closed end 23 (the left end of the track body 2 shown in Figures 2 and 4). The opening 21 communicates with the cavity 22 and the washing chamber 11, with a closed end 23 separating the cavity 22 from the washing chamber 11. The drainage hole 12 is located outside the cavity 22, and the drainage hole 12 is opposite to the opening 21. The above "relative" is used to describe the positional relationship between the opening 21 and the drainage hole 12. The track body 2 is provided with one end of the opening 21. If you follow the track body 2 The outline of Continuously extends, since the drainage hole 12 is opposite to the opening 21, the cavity 22 will cover the drainage hole 12. There is a certain distance between the opening 21 and the drainage hole 12. As shown in Figure 4, when the drainage hole is open, the water flow in the washing cavity 11 can directly flow from the gap between the drainage hole 12 and the opening 21 to the drainage hole 12. Then it is discharged from the drainage hole 12 to the outside of the laundry treatment equipment. Of course, when the amount of water in the washing chamber 11 is large, the water flow can also enter the cavity 22. In the embodiment of the present application, the cavity 22 is configured with one end open, and the water in the washing cavity 11 can flow directly from the gap between the opening 21 and the drainage hole 12 to the drainage hole 12, thereby improving the dehydration efficiency of the clothes processing equipment.

As shown in FIGS. 1 to 4 , the movable mechanism 3 can move between the first position and the second position along the cavity 22 to open and close the drainage 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 relative position between the movable mechanism 3 and the cavity 22 can be changed through the movement of the movable mechanism 3 . As shown in Figure 2, the first position represents the position where the movable mechanism 3 protrudes from the opening 21 and closes the drainage hole 12. The protruding opening 21 may be that at least a part of the movable mechanism 3 is located in the cavity 22, and the other part is located in the cavity 22. In addition, the part of the movable mechanism 3 protruding from the opening 21 closes the drainage hole 12 so that the water in the washing chamber 11 cannot flow out from the drainage hole 12 . And 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.

As shown in Figures 3-4, the second position represents the position where the movable mechanism 3 abuts the closed end 23 of the track body 2. It should be noted that abutment 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 force to press each other in the abutting state. The closed end 23 and the opening 21 are respectively located at both ends of the extending direction of the cavity 22. The extending direction of the cavity 22 is the direction of the maximum size of the cavity 22. That is to say, during the movement from the first position to the second position, the movement The mechanism 3 moves from a position partially protruding from the opening 21 to a position against the closed end 23. When the movable mechanism 3 is in the second position, the movable mechanism 3 can be completely located within the cavity 22, or it can still be partially located outside the opening 21. However, the drainage hole 12 has been opened, the movable mechanism 3 is far away from the drainage hole 12, that is, the drainage hole 12 is opened, and the water in the washing chamber 11 can be discharged from the drainage hole 12.

In the embodiment of the present application, by arranging the drainage hole at a position opposite to the opening of the track body, and the movable mechanism moving between the first position and the second position, the automatic opening and closing of the drainage hole can be realized. The drainage structure of the embodiment of the present application is simple. , which is conducive to reducing the manufacturing difficulty and cost of clothing processing equipment. And when the movable mechanism is located in the open drainage hole, the water in the washing cavity can flow directly to the drainage hole through the gap between the opening and the drainage hole, which reduces the risk of restriction and blocking of the water flow by the movable mechanism, and is conducive to improving the drainage hole The velocity of the water flow is directed such that the housing increases the efficiency of liquid discharge to the outside of the laundry treatment device.

In some embodiments, as shown in FIGS. 1-4 , the cavity 22 is arranged in an arc-shaped structure. It should be noted that the arc-shaped structure means that the extending direction of the cavity 22 is not along a straight line, but along a certain direction. In the arc direction of curvature, the closed end 23 and the opening 21 are respectively located at both ends of the cavity 22 in the arc direction. Among them, as shown in Figure 4, the arc direction can be defined as the connection direction of the closest position between the closed end 23 and the opening 21 (which can be considered as the extension direction of the inner wall surface 26 of the cavity 22). The arc direction can also be The definition is the direction of the line connecting the farthest position between the closed end 23 and the opening 21 (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 intermediate position between the closed end 23 and the opening 21. The connecting direction of the middle position (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. Hereinafter, for the convenience of description, the arc directions The 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 extending 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 representing the cavity 22 may be a fixed value. The curvature of the arc in the extending direction of the cavity 22 may change. For example, if the arc is connected by several arcs with different curvatures, then the curvature corresponding to the arc may change but there will be no sudden change in the curvature, that is, a cavity 22 There is no turning point. In the embodiment of the present application, the cavity is arranged in an arc shape, and the arc-shaped structure limits the movement range of the movable mechanism to the arc-shaped area, which is beneficial to reducing the risk of collision between the movable structure and the track body, thereby reducing the noise generated by the collision. .

In some embodiments, as shown in FIG. 4 , the track body 2 includes an outer wall 25 and an inner wall 26 , wherein the inner wall 26 is closer to the washing tub wall than the outer wall 25 , that is, the inner wall 26 is further away from the outer wall 25 . The axis of the washing tub, the outer wall 25 and the inner wall 26 define a cavity 22 for accommodating the movable mechanism 3. The inner wall 26 and the outer wall 25 are connected through a bottom wall. In some implementations, the inner wall surface 26 is formed as a supporting surface, that is, the movable mechanism 3 moves along the inner wall surface 26 in an arc shape. In other embodiments, the supporting surface is formed as an arc-shaped groove provided on the bottom wall, that is, the movable mechanism 3 moves in an arc along the arc-shaped groove formed on the bottom wall. The support surface in the embodiment of the present application can be formed on each wall surface of the track body, thereby increasing the diversity of implementation methods of the track body.

In some embodiments, as shown in FIG. 4 , both the outer wall surface 25 and the inner wall surface 26 are curved in the same direction to form an arc, and the arc length of the outer wall surface 25 is greater than the arc length of the inner wall surface 26 . Among them, 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 their bending directions are the same. As shown in Figure 4, both the outer wall surface 25 and the inner wall surface 26 protrude into the washing cavity 11, indicating that the bending directions of the two surfaces are the same. It should be noted that the same bending direction of the outer wall surface 25 and the inner wall surface 26 does not mean that they are bent in the same direction. The curvatures need to be the same, and the curvatures of the outer wall surface 25 and the inner wall surface 26 can be the same or different. When an arc is used to represent the extending direction of the cavity 22 (the arc can be selected in various ways as mentioned above), since the outer wall 25 is outside the inner wall 26, the outer wall 25 is projected on the arc. The length is greater than the projected length of the inner wall surface 26 on the arc. In the embodiment of the present application, both the inner wall surface and the outer wall surface of the cavity 22 are configured as arc surfaces, which is beneficial to guiding the movable mechanism to move in the arc-shaped cavity.

In other embodiments, the inner wall surface 26 can also be set as a flat surface, thereby increasing the The contact area between the surface 26 and the washing bucket is beneficial to improving the stability of the connection between the track body and the washing bucket.

In some embodiments, as shown in FIG. 4 , the arc 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 represented by the angle of the arc of the inner wall surface 26 represented on the longitudinal section of the track body 2 (ie, the section parallel to the extension direction of the track body as shown in FIG. 4 ). As shown in FIG. 4 , 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 represented by the angle of the arc of the outer wall surface 25 represented on the longitudinal section of the track body 2 (that is, the section parallel to the extension direction of the track body as shown in FIG. 4 ). The curvature of the outer wall surface 25 can be smaller than the curvature of the inner wall surface 26. Specifically, the inner wall surface 26 can extend half a circle, that is, 180 degrees, and one end of the outer wall surface 25 is connected to the closed end 23, and the other end of the outer wall surface 25 is The free end, that is to say, the other end of the outer wall surface 25 is not connected and contacted with other solid components, so that the extension angle of the outer wall surface 25 is less than half a circle. The free end of the outer wall surface 25 can form an opening 21 with an end of the inner wall surface 26 away from the closed end 23 , and the opening 21 is spaced apart from the drainage hole 12 . This allows the water in the washing cavity 11 to flow directly from the gap between the opening 21 and the drainage hole 12 to the drainage hole 12 without having to flow through the cavity 22 and then to the drainage hole 12, thereby improving the dehydration of the clothes treatment equipment. efficiency.

In some embodiments, as shown in FIG. 4 , both ends of the arc length direction of the inner wall 26 are connected to the washing tub 1 , and the distance L3 between the end of the outer wall 25 located at the opening 21 and the washing tub 1 is greater than or equal to The first preset value is 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 application, the distance between the outer wall located at the end of the opening and the washing bucket is less than or equal to the second preset value, so that the movement range of the movable mechanism will not be too large, thereby reducing the noise generated by the movement of the movable mechanism; For example, by limiting the distance between the outer wall at one end of the opening and the washing tub to be greater than or equal to the first preset value, the distance between the outer wall and the washing tub will not be too small, thereby ensuring smooth flow of water from between the outer wall and the washing tub. The gap flows to the drainage hole.

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 impact of the movement of the movable mechanism. noise, thereby improving user experience.

In some embodiments, as shown in FIG. 4 , 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 changing trend of the contour of the outer surface of the movable mechanism 3 is consistent with the changing trend of the contour 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 beneficial to improving the performance of the track body 2. The smoothness of the movement of the movable mechanism relative to the track body is also conducive to reducing the noise caused by the impact between the track body and the movable mechanism, thereby improving the user experience.

In some embodiments, as shown in Figure 1, the movable mechanism 3 is arranged in an arc-shaped 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 and the extension direction of the movable mechanism They may be the same, or they may not be parallel, that is, the extension direction of the cavity and the extension direction of the movable mechanism may be different. In the embodiment of the present application, the movable mechanism 3 is arranged into an arc-shaped structure. 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 realization of the movable mechanism through the movement of the movable mechanism. The fit and separation from the drainage hole is conducive to realizing the movement of the movable mechanism in a small space to open and close the drainage hole.

In some embodiments, as shown in FIG. 4 , 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. Wherein, 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 arranged in an arc-shaped structure, the length of the movable mechanism 3 can be in the second arc direction of the movable mechanism itself. biggest size. In the embodiment of the present application, the length of the movable mechanism 3 is set to be less than or equal to 0.9 times the first dimension, so that the distance between the movable mechanism and the drainage hole is not too close, thereby reducing the impact of the movable mechanism on the drainage hole in the second position. interference, thereby helping to increase the speed of liquid diversion from the washing chamber to the drainage hole; set the length of the movable mechanism 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 Larger, it further limits the movement range of the movable mechanism, thereby reducing the noise generated by the movement of the movable mechanism, which is beneficial to improving the user experience.

In some embodiments, as shown in FIG. 2 , the movable mechanism 3 includes a slider 31 , a weight block 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 at least partially roll relative to the track body. The slider 31 has an opposite first end 311 and a second end 312 in an extension direction. The extension direction represents the maximum size direction of the slider 31. When the slider 31 extends along an arc direction, the slider 31 The first end 311 and the second end 312 are at opposite ends in the arc direction. Among them, the first end 311 is close to the drainage 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 drainage hole 12 relative to the positional relationship between the second end 312 and the drainage hole 12. In other words, 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 is in contact with the drainage hole 12, and the second end 312 is spaced apart from the closed end 23; when the movable mechanism 3 is in the second position, the slider 31 The second end 312 of 31 is in contact with the closed end 23 , and the first end 311 is spaced apart from the drainage hole 12 . The counterweight 32 is disposed close to the second end 312 of the slider 31 . “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 counterweight The distance from the block to the second end is less than 1/2 the distance between the first and second ends. The elastic member 33 is disposed between the slider 31 and the track body 2. The elastic member 33 has the ability to deform and recover deformation. The elastic member 33 in the embodiment of the present application includes but is not limited to springs and elastic balls. Taking the elastic member 33 as a spring as an example, the two ends of the spring do not necessarily have a fixed connection relationship 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 counterweight block 32 independent of the slider 31 may not be provided, but the mass of the part of the slider 31 close to the second end may be set larger. The first end 311 of the slider can be regarded as the spool, which is used to adjust the elasticity of the spring. The drain hole 12 is opened and closed under the combined action of force, centrifugal force of the counterweight, gravity, etc.

With reference to Figures 1 to 4, the movement process of the slider 31 is described below:

The laundry processing equipment in Figures 1 and 2 is in a non-dehydration state, which includes a soaking state, a washing state, a non-working state, etc., and the first end 311 of the slider 31 is pressed against the elastic force of the elastic member 33 The drainage hole 12 and the movable mechanism 3 are located in the first position to close the drainage hole 12 . And in the non-dehydration state, the rotation speed of the washing bucket 1 is low or the rotation speed of the washing bucket 1 is zero. The centrifugal force generated by the counterweight 32 due to the slow rotation speed or non-rotation of the washing bucket 1 is low or zero, and the centrifugal force is not enough. Overcoming the elastic force generated by the elastic member 33 on the slider 31 , the slider 31 is stably maintained in the first position of closing the drainage hole 12 .

The clothes processing equipment in Figures 3 and 4 is in a dehydration state. The washing barrel 1 rotates in the circumferential direction (the direction indicated by the arrow in Figure 4). The rotation speed of the washing barrel 1 is higher in the dehydration state. As the rotation speed increases, the equipment The greater the centrifugal force F of the weight 32. When the centrifugal force F generated by the counterweight 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 exerted by the elastic member 33 on the slider 31, so that the counterweight The centrifugal force F generated by the block 32 can drive the slider 31 to move relative to the track body 2 , and the slider 31 moves from a first position protruding from the opening 21 to a second position abutting the closed end 23 . In the second position, the second end 312 of the slider 31 abuts the closed end 23 and the first end 311 of the slider 31 opens the drainage hole 12 so that the water in the washing chamber 11 can be discharged from the drainage hole 12 to Exterior of laundry handling equipment.

In some embodiments, as shown in FIGS. 4-6 , when the movable mechanism 3 has an arc-shaped structure as a whole and extends along the second arc direction, the slider 31 moves from the first end 311 to the second end 312 Extending along the second arc direction, the slider 31 is set in an arc-shaped structure, the elastic member 33 is set at a position of the slider 31 close to the first end 311, and the counterweight block 32 is set at a position of the slider 31 close to the second end, that is, That is, distributing the elastic members 33 and the counterweights 32 at both ends of the arc-shaped structure is helpful to guide the movement of the slider 31 relative to the track body 2, thereby improving the reliability of the slider opening and closing the drainage holes.

In some embodiments, as shown in FIG. 2 , the arc of the slider 31 from the first end 311 to the second end 312 is greater than or equal to 90 degrees and less than or equal to 160 degrees. The second end 312 is connected along an arc direction to form a partial circumference. The arc of the partial circumference is greater than or equal to 90 degrees and less than or equal to 160 degrees. In the embodiment of the present application, the upper end of the arc from the first end to the second end of the slider is defined. limit, so that the structure of the slider does not change too much, thereby reducing the interference of the slider on the liquid flow at the drainage hole; by limiting the lower limit of the arc of the slider from the first end to the second end, the structure of the slider is The changes will not be too small, thus reducing the difficulty of slide manufacturing.

In some embodiments, as shown in FIGS. 4 and 5 , the slider 31 opens an accommodation cavity 314 for accommodating the counterweight block 32 near the second end 312 , and the counterweight block 32 is connected to the accommodation cavity 314 . It should be noted that the connection between the counterweight block 32 and the slider 31 includes the counterweight block 32 being disposed in the accommodating cavity 314 so that the accommodating cavity 314 limits the position of the counterweight block 32 so that the counterweight block 32 will not escape from the accommodating cavity 314 That's it, and there is no need for the counterweight block 32 and the slider 31 to have a direct connection relationship. In other embodiments, the counterweight block can be integrally molded with the slider. That is to say, during the manufacturing process of the movable mechanism, the counterweight block can be integrally injection molded with the slider. The counterweight block can be injection molded to have a higher density and For a heavier structure, the slider can be injection molded into a lighter structure; or the counterweight block 32 can be fixedly connected to the slider 31 .

In the embodiment of the present application, the counterweight block is arranged in the accommodation cavity and connected to the slider, so that the counterweight block and the slider are integrated. On the one hand, the counterweight block can be produced separately from the slider, which reduces the difficulty of manufacturing and thus reduces the processing of clothes. The production cost of the equipment is reduced. On the other hand, the integrated assembly of the counterweight block and the slider is conducive to simplifying the structure of the movable mechanism and the movement method of the movable mechanism, thereby simplifying the drainage method of the single-tub clothing processing equipment.

In some embodiments, as shown in FIG. 6 , the slider 31 includes a main body portion 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 accommodation cavity 314 , and the second end 312 Located in installation section 318. Specifically, the mounting portion 318 can be roughly configured as a spherical structure, and the accommodation cavity 314 formed inside the mounting portion 318 can also be configured as a cylindrical, spherical, etc. shape. The mounting part 318 in the embodiment of the present application is fixedly connected to the main body part 317. In some embodiments, the mounting part 318 and the main body part 317 can be integrally injection molded. The embodiment of the present application divides the slider into a main body part and an installation part, so that the assembly method of the counterweight block and the slider is simple, which is beneficial to improving the assembly efficiency of the movable mechanism.

In some embodiments, as shown in FIG. 6 , the mounting portion 318 is provided with an opening 3141 that communicates with the accommodation cavity 314 . The counterweight block 32 can be manufactured separately from the slider 31 . During the assembly process, the counterweight block 32 It can be assembled into the accommodation 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 block 32, and at least part of the counterweight block 32 can be configured as an elastic structure. That is to say, the counterweight block 32 can fit a smaller size during the assembly process. The opening 3141 undergoes elastic deformation. After the counterweight 32 completely moves to the accommodation cavity 314, the counterweight 32 resumes its elastic deformation, making the maximum cross-sectional area of the counterweight 32 larger than the size of the opening, thereby limiting the counterweight 32 After assembly, the receiving chamber 314 is exited through the opening 3141 . Of course, in other embodiments, the portion of the mounting portion 318 close to the opening 3141 can also be configured as an elastic structure, so that during the assembly process of the counterweight block 32 and the mounting portion 318, the size of the opening 3141 will elastically increase. After the assembly is completed, the size of the opening 3141 is restored to be smaller than the maximum cross-sectional area of the counterweight 32 . The structure of the mounting part and the counterweight block in the embodiment of the present application includes but is not limited to the above two forms.

As shown in FIG. 6 , the structure in which the mounting portion 318 and the counterweight 32 cooperate will be described in detail below. The mounting portion 318 is provided with a plurality of slits 3142 spaced apart along the circumferential direction of the opening 3141 , and the slits 3142 are in communication with the accommodation cavity 314 . In the embodiment of the present application, a 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, when the counterweight 32 is assembled to the slit through the opening 3141 Before the accommodation cavity 314, the opening 3141 is not subject to external force in its natural state, and the maximum cross-sectional area of the counterweight block 32 is larger than the size of the opening 3141 in its natural state; during the process of assembling the counterweight block 32 into the accommodation cavity 314 , the counterweight block 32 is pressed by an external force to the mounting portion 318 around the opening 3141, and the mounting portion 318 is elastically deformed by the force of the counterweight block 32, so that the mounting portions 318 adjacent to the slit 3142 are close to each other, and the slit is 3142 becomes narrower, and the opening 3141 continues to increase to a size that can allow the counterweight block 32 to pass; when the counterweight block 32 is completely assembled into the accommodation cavity 314, the mounting portion 318 around the opening 3141 is not affected by the counterweight. When the block 32 is squeezed, the mounting part 318 recovers its elastic deformation, and the mounting parts 318 adjacent to the slit 3142 move away from each other, so that the slit 3142 becomes wider, and the opening 3141 returns to a size smaller than the maximum cross-sectional area of the counterweight block 32, thereby The counterweight 32 is restricted from being separated from the accommodation cavity 314 . By arranging multiple slits in the circumferential direction of the opening, the embodiment of the present application is conducive to improving the elasticity of the mounting portion near the opening, thereby improving the fatigue strength of the mounting portion and reducing the friction between the counterweight block and the accommodation cavity. difficulty and improve assembly efficiency.

In some embodiments, as shown in FIG. 6 , the slider 31 also includes a plurality of reinforcing ribs 319 . The reinforcing ribs 319 include first reinforcing ribs 3191 and second reinforcing ribs 3192 . The first reinforcing rib 3191 is provided along the length direction of the slider 31, and the first reinforcing rib 3191 is connected to the main body part 317. The first reinforcing rib 3191 can be integrally injection molded with the main body part 317. In the embodiment of the present application, the first reinforcing rib 3191 is provided by providing the first reinforcing rib. , which can not only improve the structural strength of the main body, but also reduce the material used in the manufacture of the slider. The second reinforcing rib 3192 is provided along the width direction of the slider 31 and is connected to the first reinforcing rib 3191 . At least part of the second reinforcing rib 3192 is adjacent to the groove 313 . Among them, the length direction of the slider represents the direction of the largest size of the slider, and the width direction represents the vertical and length directions. The second reinforcing rib 3192 can be integrally injection molded with the main body portion 317 and the first reinforcing rib 3191, and the first reinforcing rib 3191 and the second reinforcing rib 3192 can be provided in multiple numbers. In this embodiment of the present application, by providing second reinforcing ribs, the structural strength of the main body can be further improved.

In some embodiments, as shown in FIG. 7 , the first end 311 of the slider 31 is set as a first arc surface. The first arc surface means that the surface is a curved surface rather than a plane, and the curvature of the curved surface is the same or although The curvature is different but the transition is smooth with no inflection points. Wherein, when the first end 311 is in contact with the drainage 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 Surface contact can be formed with the wall surface around the drainage hole. When the curvature radius of the first arc-shaped surface is smaller than the curvature radius of the washing bucket, line contact can be formed between the first arc-shaped surface and the wall surface surrounding the drainage hole.

In some embodiments, as shown in FIG. 7 , a folding edge 13 is provided near the drainage hole 12 of the washing tub. The extending direction of the folding edge is inconsistent with the extending direction of the original wall of the washing tub. The folding edge 13 is relative to the adjacent washing tub. The wall portion of the barrel extends toward the side away from the washing chamber 11 . At the position where the first end 311 closes the drainage hole 12, by setting the curvature of the surface of the flange 13, the first end 311 and the flange 13 can be made to fit together, which can be regarded as surface contact between the first end 311 and the drainage hole 12. . By bringing the first end 311 of the slider into surface contact with the flange 13 around the drainage hole 12, the contact area is larger. When the movable mechanism is in the first position, it is difficult for the water in the washing chamber 11 to flow from the first end 311. It flows out between the first end and the drainage hole 12, thereby improving the sealing performance between the first end and the drainage hole.

In some embodiments, as shown in FIG. 7 , the first arc-shaped surface (refer to the first end 311 shown in FIG. 7 ) is a circular mesa, and the diameter L4 of the circular mesa gradually decreases toward the drainage hole 12 . It should be noted that the truncated cone does not mean that the first end 311 of the slider has a standard truncated cone shape, but that the cross-sectional area (the area of the cross-section perpendicular to the extension direction of the slider) of the first end 311 of the slider is in the direction of It decreases close to the drainage hole 12, which is similar to the change of the cross-sectional area of a truncated cone, so it is called a truncated cone. The slider in the embodiment of the present application can be formed by injection molding, by setting the first arc-shaped surface into a circle. The tabletop facilitates mold drawing during the manufacturing process, which is beneficial to improving the processing efficiency of the slider; and the round tabletop and the periphery of the convex ribs fit more closely, which is beneficial to improving the sealing performance of the clothing processing equipment during the washing process.

In some embodiments, as shown in FIG. 7 , the slider 31 also includes an inner edge 315 and an outer edge 316 connecting 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 . The 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 the curvature of the inner edge 315. In the embodiment of the present application, by setting the outer edge and the inner edge of the slider to have the same arc, it is advantageous to manufacture the structure of the track body so that it can be quickly assembled with the cavity in the track body, thereby improving the assembly efficiency.

In some embodiments, as shown in FIG. 6 , the second end 312 of the slider 31 is configured as a second arc surface. The second arc surface means that the surface is a curved surface rather than a plane, and the curvature of the curved surface is the same or although The curvature is different but the transition is smooth with no inflection points. When the second end 312 is in contact with the closed end 23, the second end 312 is in point contact with the closed end 23; for example, the surfaces of the second end 312 and the closed end 23 of the sliding block in contact are both curved surfaces with different bending directions. Then, when the contact is made, it is a point contact. In the embodiment of the present application, the arrangement of the slider in contact with the closed end point of the track body is beneficial to improving the smoothness of the slider movement, reducing the risk of the slider getting stuck in the cavity, and improving the position of the slider in the first position and the second position. Efficiency of location switching.

In some embodiments, as shown in conjunction with Figures 1, 8 and 9, at least part of the movable mechanism 3 is rollable. 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. The second part can move along the cavity 22 like the first part and can also move relative to the first part. Rotate in another direction, thereby realizing the rolling of the movable mechanism 3 part relative to the track body 2; then, the friction between the part of the movable structure in rolling contact with the track body 2 and the track body 2 is rolling friction rather than sliding friction.

Taking one part of the movable mechanism 3 as being rotatable relative to another part as an example, as shown in FIG. 8 , the counterweight block 32 and the slider 31 are rotatably connected. That is to say, during the movement of the movable mechanism 3 relative to the track body, the surface of the counterweight 32 is in contact with the track body 2, and the friction between the counterweight 32 and the track body 2 will drive the counterweight 32 relative to the slider. 31 rotates, thereby realizing the counterweight block 32 rolling relative to the track body.

The elastic member 33 in the embodiment of the present application includes but is not limited to springs and elastic balls. Taking the elastic member 33 as a spring as an example, the two ends of the spring do not necessarily have a fixed connection relationship 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, as shown in FIG. 5 , the slider 31 is provided with a groove 313 , and the extension direction of the groove 313 may be consistent with the extension direction of the slider 31 . For example, when the slider 31 is arranged along an arcuate direction, the groove 313 is arranged along the same arcuate 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 protruding means that the first protrusion 24 can partially extend into the groove 313, and the other part extends into the groove 313. Located outside the groove 313; it can also mean that the first protrusion 24 completely extends into the groove 313. The first protrusion 24 is completely arranged in the groove 313, which is beneficial to reducing the assembly time of the slider 31 and the track body 2. space. 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 smaller than the distance from the groove 313 away from the closed end 23 The distance from one end to the closed end.

The assembly process of the movable mechanism 3 and the track body 2 to form the drain valve 6 will be described below. First, install the elastic member 33 into the groove 313 of the slider 31. Since the length of the groove 313 is smaller than the natural length of the elastic member 33, the elastic member 33 is compressed; then, install the slider 31 and the elastic member 33 together. Assemble with the track body 2. Specifically, put the slider 31 and the elastic member 33 into the track body. 2, so that the first protrusion 24 abuts the end of the elastic member 33 away from the opening 21.

At this position, the elastic member 33 is compressed to the greatest extent and the corresponding elastic force is the greatest. After canceling After assembly, 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, the position shown in Figure 2. In this position, due to The length of the groove 313 is smaller than the natural length of the elastic member, so 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 stable position blocking the drainage hole 12 in the non-dehydrated state.

In the dehydrated state, the centrifugal force of the counterweight 32 is greater than the elastic force, thereby driving the slider 31 to move to the second position shown in Figure 4. In this position, the elastic member 33 is squeezed to the maximum deformation state, corresponding to Maximum elasticity. After the dehydration is completed, the centrifugal force of the counterweight 32 is reduced or disappears, and the elastic member 33 acts on the slider 31 with elastic force, thereby driving the slider 31 to return to the first position shown in FIG. 2 .

In the embodiment of the present application, a groove is provided on the slider. The groove can limit the deformation and deformation recovery process of the elastic member. The relative movement of the groove will also be limited by the first protrusion.

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 application 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 application, the distance from the groove to the second end is greater than the distance from the groove to the first end, so that the groove is closer to the first end relative to the second end, which is beneficial to improving the energy converted from the elastic force to the first end, thereby In the non-dehydrated state, it is beneficial to improve the reliability of the contact between the first end of the slider and the drainage hole.

The lifting rib 5 is arranged in the washing cavity 11 and connected with the washing bucket 1. The lifting rib 5 is provided with an installation cavity 51 connected with the washing cavity. , the drain valve 6 in the embodiment of the present application is indirectly connected to the washing tub 1 through the lifting rib 5 . The indirect connection means that the drain valve 6 can be at least partially stationary relative to the lifting rib 5 and the washing tub 1 . Specifically, the drain valve 6 is disposed in the installation cavity 51, and the drain valve 6 can move at least partially relative to the installation cavity 51, thereby closing and opening the drainage hole 12. It should be noted that the drain valve 6 in the embodiment of the present application includes the drain valve structure described in any of the above embodiments, which includes a track body 2 and a movable mechanism 3 .

It should be noted that the lifting ribs 5 are convex structures relative to the inner wall of the washing tub 1 . The lifting ribs 5 are used to generate friction with the clothes in the washing cavity 11 . The parts of the clothes close to the lifting ribs 5 are different from the parts far away from the lifting ribs 5 . Some parts rub against each other to produce a kneading effect; in addition, the lifting ribs can drive the clothes to rotate together, and the clothes are lifted out of the liquid level and sent to a certain height. The clothes fall back into the washing liquid due to gravity, and the collision between the clothes and the liquid produces a stick. and the effect of falling, thus improving the cleaning degree of clothes.

In some embodiments, as shown in Figure 18, the limiting part is provided with a first connection part 61, and the lifting rib 5 is provided with a second connection part 62. The first connection part 61 cooperates with the second connection part 62 to limit drainage. The valve 6 moves in the circumferential direction of the washing tub 1 relative to the lifting rib 5 . The circumferential direction of the washing tub 1 represents the direction of rotation around the axial direction of the washing tub 1 . Of course, in some embodiments, the cooperation between the first connecting part 61 and the second connecting part 62 can also 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 represents the direction of any straight line perpendicular to the axial direction of the washing tub 1 .

The following is an example of the specific manner in which the first connection part 61 and the second connection part 62 are arranged:

As shown in FIGS. 18-20 , the first connecting part 61 may be configured as a protrusion, and the second connecting part 62 may be configured as a groove. Among them, the convex structure of the first connecting part 61 is formed separately on the surface of the drain valve 6, or it can also be formed by the existing structure on the surface of the track body 2. For example, as shown in FIG. 15, the first cover body 27 and the third The two cover bodies 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 the first connecting portion 61 for matching with the lifting rib.

In the embodiment of the present application, a third boss and a fourth boss form a first connection part, which not only satisfies the positioning and matching of the first cover body and the second cover body, but also realizes the matching limit with the lifting rib, and has It is conducive to simplifying the structure of the connection between the lifting rib and the drain valve, and improving the space utilization of the clothes processing equipment.

It should be noted that the first connecting part can also be configured as a groove, and the corresponding second connecting part can be configured as a protrusion. During the cooperation between the drain valve and the lifting rib, the second connecting part can be extended into the first connecting part. . The principle of this cooperation is consistent with the above-mentioned embodiment, and therefore will not be described again.

In some embodiments, as shown in Figures 21 and 22, Figure 21 is a bottom perspective view of the lifting rib. Figure 22 shows a schematic cross-sectional view of the connection between the lifting rib and the drain valve. As shown in Figure 22, 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 parallel to the axial direction of the washing tub 1 (the direction perpendicular to the paper surface in Figure 22). When the lifting ribs are connected to the drain valve, the fifth surface 63 and the sixth surface 64 abut, thereby limiting the radial movement of the drain valve 6 relative to the lifting ribs 5 in the washing tub 1. It should be noted that the washing tub 1 The radial direction represents the direction of any straight line passing through the axis of the washing tub on the parallel paper surface in Figure 22. The fifth surface and the sixth surface in Figure 22 are both perpendicular to the radial direction.

In some embodiments, as shown in Figure 22, the cross-section of the lifting rib 5 can be configured as a tapered structure. That is to say, the width of the lifting rib 5 ranges from one end close to the inner wall of the washing tub (the lower end shown in Figure 22) to one far away from the washing tub. The inner wall of the barrel tapers off at one end. The width represents the size of the lifting rib 5 in the left-right direction in FIG. 22 . In the embodiment of the present application, by arranging the lifting ribs into a tapered structure, the width of the connection between the lifting ribs and the washing bucket is larger, which is beneficial to improving the strength of the connection between the lifting ribs and the washing bucket; on the other hand, the lifting ribs are on the side away from the washing bucket The narrow width can limit one end of the drain valve. Through the lifting rib-shaped structure and the contact between 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 restrict the downward movement of the drainage valve relative to the lifting rib as shown in Figure 22, and the tapered structure of the lifting rib can restrict the upward movement of the drainage valve relative to the lifting rib as shown in Figure 22, thereby achieving up and down control.

The other end of the clamping member 52 (the lower end shown in FIG. 22 ) may be provided with a structure protruding toward the width direction of the lifting rib (the left-right direction shown in FIG. 22 ). The assembly process of the drain valve 6 and the lifting rib 5 is explained with reference to Figure 22. 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 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 resumes its elastic deformation, so that the fifth surface 63 and The sixth surface 64 abuts, and one side of the latch 52 (the side in the left-right direction shown in FIG. 22 ) abuts against the side of the drain valve 6 , thereby restricting the movement of the drain valve and the lifting rib in the width direction.

In some embodiments, as shown in FIG. 22 , the clamping members 52 can be arranged in pairs. A pair includes two clamping members 52 , and the two clamping members 52 are respectively arranged at intervals in the width direction of the lifting rib 5 . The clamping members 52 are arranged opposite each other and can limit the positions of both sides of the drain valve in the width direction, which is beneficial to improving the stability of the connection between the drain valve and the lifting rib.

In some embodiments, as shown in FIG. 22 , 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 application limits the positional relationship between the fifth surface and the track body, that is, the fifth surface is provided close to the bottom surface of the track body, which is beneficial to reducing the difficulty of assembling the lifting ribs and the drain valve, and can also improve the compactness of the assembly. .
