In some embodiments, the curvature of the arc representing the direction in which the cavity 22 extends may be a fixed value, e.g., the arc is an arc of a circle whose corresponding curvature is constant; in other embodiments, the curvature of the arc representing the extending direction of the cavity 22 may be variable, for example, the arc is formed by connecting several arcs with different curvatures, and the curvature corresponding to the arc may be variable but the curvature does not change abruptly, that is, the cavity 22 has no inflection point.

The centers of the arcs corresponding to the outer wall surface 25 and the inner wall surface 26 are located on the same side, which means that the two arc directions are the same. As shown in fig. 4, the outer wall surface 25 and the inner wall surface 26 both protrude into the washing chamber 11, and the bending directions of the outer wall surface 25 and the inner wall surface 26 are the same, which does not mean that the curvatures of the two are the same, and the curvatures of the outer wall surface 25 and the inner wall surface 26 may be the same or different. In the case where the extending direction of the cavity 22 is expressed by an arc (the arc may be variously selected as described above), since the outer wall surface 25 is outside the inner wall surface 26, the projection length of the outer wall surface 25 on the arc is larger than the projection length of the inner wall surface 26 on the arc.

In some embodiments, as shown in connection with FIG. 4, the arc of 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 a longitudinal section of the rail body 2 (i.e., a section parallel to the extending direction of the rail body shown in fig. 4). As shown in fig. 4, the radian of the outer wall surface 25 is 135 degrees or more and 170 degrees or less. The curvature of the outer wall surface 25 is represented by the angle of the arc line of the outer wall surface 25 represented on the longitudinal section of the rail body 2 (i.e., the section parallel to the extending direction of the rail body shown in fig. 4). The radian of the outer wall surface 25 may be smaller than that of the inner wall surface 26, specifically, the inner wall surface 26 may extend by half a circumference, that is, 180 degrees, 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 a free end, that is, the other end of the outer wall surface 25 is not connected to or contacted with other solid components, so that the extension angle of the outer wall surface 25 is smaller than half a circumference. Wherein, the free end of the outer wall surface 25 and the end of the inner wall surface 26 far away from the closed end 23 can form an opening 21, and the opening 21 is arranged at a distance from the drainage hole 12.

The smooth contact shows that the change trend of the outline of the outer surface of the movable mechanism 3 is consistent with the change trend of the outline of the inner surface of the track body 2, so that the outer surface of the movable mechanism 3 is mutually attached to the inner surface of the track body 2, the improvement of the smoothness of the movement of the movable mechanism relative to the track body is facilitated, the reduction of noise generated by impact between the track body and the movable mechanism is facilitated, and the experience of a user is improved.

In some embodiments, as shown in fig. 1, the movable mechanism 3 is provided in an arcuate configuration. Specifically, the longitudinal direction (direction in which the dimension is largest) of the entire movable mechanism 3 is not a linear direction but an arc direction having a curvature. For the purpose of distinguishing from the arc direction of the cavity above, the arc direction of extension of the movable mechanism 3 is referred to as a second arc direction. It will be appreciated that the direction of the arc and the direction of the second arc may be parallel, i.e. the cavity may extend in the same direction as the direction of the movable member, or may be non-parallel, i.e. the cavity may extend in a different direction than the direction of the movable member.

Wherein the first dimension is a length from the first position to the second position in an arc direction, the arc direction indicating a direction of extension of the cavity. Note that the length of the movable mechanism 3 is the length in the direction of the maximum dimension of the movable mechanism, and in the case where the movable mechanism 3 is provided in an arc-shaped configuration, the length of the movable mechanism 3 may be the maximum dimension in the direction of the second arc of the movable mechanism itself. The embodiment of the utility model sets the length of the movable mechanism 3 to be less than or equal to 0.9 times of the first size, so that the distance between the movable mechanism and the drain hole is not too close, the interference of the movable mechanism to the drain hole in the second position state is reduced, and the speed of guiding the liquid from the washing cavity to the drain hole is improved; the length of the movable mechanism is set to be larger than or equal to 0.7 times of the first size, so that the movable space between the movable mechanism and the track body is not too large, the movement amplitude of the movable mechanism is further limited, the noise generated by movement of the movable mechanism is reduced, and the user experience is favorably improved.

In some embodiments, the sliding block 31 can slide relative to the track body 2, and in other embodiments, can also at least partially roll relative to the track body. The slider 31 has a first end 311 and a second end 312 opposite to each other in an extending direction, which indicates a direction of a maximum dimension of the slider 31, and in a case where the slider 31 extends in an arc direction, the first end 311 and the second end 312 of the slider 31 are opposite to each other in the arc direction. Wherein 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 rail body 2, it can be understood that the position relationship between the first end 311 and the drainage hole 12 is relative to the position relationship between the second end 312 and the drainage hole 12, and the position relationship between the second end 312 and the closed end 23 is relative to the position relationship between the first end 311 and the closed end 23. With the movable mechanism 3 in the first position, the first end 311 of the slider 31 is in contact with the drain hole 12, and the second end 312 is spaced from the closed end 23; with the movable mechanism 3 in the second position, the second end 312 of the slider 31 is in contact with the closed end 23, and the first end 311 is spaced from the drain hole 12. The weight 32 is disposed proximate to the second end 312 of the slider 31, where "proximate" indicates that the weight 32 is closer to the second end 312 than the weight 32 is to the first end 311, e.g., the weight is closer to the second end than 1/2 of the distance between the first and second ends. The elastic member 33 is disposed between the sliding block 31 and the track body 2, and the elastic member 33 has deformation and deformation recovery capabilities, and the elastic member 33 in the embodiment of the present invention includes but is not limited to a spring, a resilient ball, and the like.

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 drained from the drain hole 12 to the outside of the laundry treating apparatus.

Wherein, under the condition that 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 that of the washing tub, the first arc surface can form surface contact with the wall surface around the drain hole, and when the curvature radius of the first arc surface is smaller than that of the washing tub, the first arc surface can form line contact with the wall surface around the drain hole.

In some embodiments, as shown in fig. 7, the washing tub is provided with a hem 13 near the drain hole 12, the hem extending in a direction different from the direction in which the original wall of the washing tub extends, and the hem 13 extends toward a side away from the washing chamber 11 with respect to the portion of the wall of the washing tub adjacent thereto. At the position where the first end 311 closes the drainage hole 12, the curvature of the surface of the folded edge 13 is set so that the first end 311 is attached to the folded edge 13, and the first end 311 is considered to be in surface contact with the drainage hole 12. The contact area is increased by surface-contacting the first end 311 of the slider with the folded edge 13 around the drain hole 12, so that the water in the washing chamber 11 is less likely to flow out from between the first end 311 and the drain hole 12 in a state where the movable mechanism is located at the first position, and the sealing property between the first end and the drain hole can be improved.

In some embodiments, as shown in fig. 7, the first arcuate surface (referring to first end 311 shown in fig. 7) is a rounded mesa having a diameter L4 that gradually decreases toward the drain hole 12. The circular truncated cone is not a description that the first end 311 of the slider has a standard circular truncated cone shape, but a description that the cross-sectional area (the area of the cross-section perpendicular to the extending direction of the slider) of the first end 311 of the slider decreases toward the drain hole 12, and is called a circular truncated cone, similarly to the change in the cross-sectional area of the circular truncated cone. The sliding block in the embodiment of the utility model can be formed by injection molding, and the first arc surface is arranged as the round table surface, so that the die drawing is convenient in the manufacturing process, and the processing efficiency of the sliding block is improved; and the round table surface is more tightly attached with the periphery of the convex rib, which is beneficial to improving the sealing performance of the clothes treatment equipment in the washing process.

In some embodiments, as shown in fig. 6, the second end 312 of the slider 31 is configured as a second curved surface, which means that the surface is a curved surface rather than a flat surface, and the curved surfaces have the same curvature or have smooth transition without inflection points although the curvature is different. With second end 312 in contact with closed end 23, second end 312 is in point contact with closed end 23; for example, the surfaces of the second end 312 and the closed end 23 of the slider that contact each other are curved and have different bending directions, so that the contact is point contact. The embodiment of the utility model provides a through the setting of the blind end point contact of slider and the track body, be favorable to improving the smoothness degree of slider motion, reduce the risk that the slider blocked in the cavity to improve the efficiency that the slider switched at primary importance and second place.

For example, the movable mechanism 3 may be divided into two parts, a first part being movable along the cavity 22 relative to the rail body 2, and a second part being rotatable in another direction relative to the first part, in addition to being movable along the cavity 22 as the first part, so as to enable the movable mechanism 3 part to roll relative to the rail body 2; then, the friction between the portion of the movable structure that is in rolling contact with the rail body 2 and the rail body 2 is rolling friction rather than sliding friction.

For example, one part of the movable mechanism 3 can rotate relative to the other part, as shown in fig. 8, the weight 32 is rotatably connected to the sliding block 31. That is to say, in the process of the movement of the movable mechanism 3 relative to the track body, the surface of the balancing weight 32 contacts with the track body 2, and the friction force between the balancing weight 32 and the track body 2 can drive the balancing weight 32 to rotate relative to the sliding block 31, thereby realizing the rolling of the balancing weight 32 relative to the track body. The embodiment of the utility model provides a through rotationally being connected balancing weight and slider, realize moving mechanism and track body rolling contact, be favorable to reducing the produced frictional force of the relative moving mechanism motion of the track body to reduce the hindrance of the track body to the moving mechanism motion, improve the smoothness degree of moving mechanism motion.

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.
