As shown in fig. 8, the first guiding section 131 may be a guiding step, that is, the first guiding element 130 is formed by at least two guiding steps connected with each other, and each time the second guiding element 140 moves on the first guiding element 130, the first clutch element 110 is driven to move a certain distance, so that the second guiding element 140 is driven to rotate to drive the first clutch element 110 to axially displace. And at least two stages of strokes of the first clutch member 110 can be satisfied, thereby realizing a multifunctional washing and dehydrating mode of the laundry treating apparatus. Of course, the first guide member 130 may also be configured as a spiral guide rail, and the second guide member 140 is adapted to the structure of the first guide member 130, so that the second guide member 140 may be moved along the spiral guide rail by rotating the second guide member 140, and the spiral guide rail may be configured, that is, the spiral guide rail has at least two sections of spiral structures, so that the first clutch member 110 may be moved by at least two distances.

In addition, by providing the first guide 130 as at least two connected first guide segments 131, the coupling strength between the first guide 130 and the second guide 140 can be improved, and the spiral track of the second guide 140 can be effectively defined, ensuring effective coupling between the first guide 130 and the second guide 140. And can avoid setting up first guide into the bump structure in the correlation technique to make bump structure and second guide cooperate and carry out axial displacement, and because bump intensity is low, lead to the poor problem of cooperation stability of second guide and first guide, through setting up the first guide section 131 of two at least connections, can guarantee effective cooperation of first guide 130 and second guide 140, thereby promote clutch 200's job stabilization nature.

As shown in fig. 8, further, the first guide section 131 includes a first guide surface 1310 and a first limiting surface 1311, the first limiting surface 1311 is connected to the first guide surface 1310, and the second guide member 140 can move along the first guide surface 1310 to the first limiting surface 1311.

Further, when the second guide member 140 moves to the first limiting surface 1311 along the first guiding surface 1310, the first clutch member 110 is driven to move for a certain stroke, and the second guide member 140 can be in limiting fit through the first limiting surface 1311, so that the stability of the first clutch member 110 after each stroke is moved is ensured on the basis of meeting the requirement of multi-stage displacement of the first clutch member 110.

The connection between the first guide surface 1310 and the first limiting surface 1311 may be set to be an arc transition, so that the second guide member 140 and the first guide member 130 can be further ensured to be matched with each other more smoothly, and the accurate control of the clutch device 200 in the laundry treating device process is realized.

As shown in fig. 8, in a specific embodiment, further, of the at least two first guide segments 131, the first guide surface 1310 of one first guide segment 131 of the adjacent two first guide segments 131 is connected with the first stop surface 1311 of the other first guide segment 131 of the adjacent first guide segments 131.

In this embodiment, the first guide surface 1310 defining one first guide segment 131 of the adjacent two first guide segments 131 is connected to the first stop surface 1311 of the other first guide segment 131 of the adjacent two first guide segments 131, i.e., defines the specific configuration of the first guide 130. It can be understood that the structure of the first guide member 130 is configured as a plurality of steps formed by one step surface and one step side wall, one step can enable the second guide member 140 to move for one stroke, and the purpose that the second guide member 140 drives the first clutch member 110 to move for multiple strokes can be achieved by arranging a plurality of steps.

In addition, through setting up the step and carrying out the removal cooperation with second guide 140, can avoid setting up first guide into the bump structure in the related art to make bump structure and second guide cooperate and carry out axial displacement, and because bump intensity is low, lead to the poor problem of the cooperation stability of second guide and first guide, through setting up the first guide section 131 of two at least connections, can guarantee the effective cooperation of first guide 130 and second guide 140, thereby promote clutch 200's job stabilization nature.

It can be appreciated that when the second guide member 140 cooperates with the first guide member 130 to move, one second guide section 141 moves along the first guide surface 1310 of the first guide section 131 to the first limiting surface 1311 to stop moving, so that the second guide member 140 drives the first clutch member 110 to move for a certain stroke. Further, when the second guide member 140 continues to move, one second guide section 141 continues to move along the first guide surface 1310 of the other first guide section 131, and at the same time, the next second guide section 141 connected to one second guide section 141 moves along the first guide surface 1310 of the first guide section 131, and when one second guide section 141 moves to the first limit surface 1311 of the other first guide section 131, the other second guide section 141 also moves to the first limit surface 1311 of the first guide section 131, and simultaneously limits the second limit surfaces 1411 of the two second guide sections 141 through the first limit surfaces 1311 of the two first guide sections 131, so that the second guide member 140 drives the first clutch member 110 to move for a further stroke. If the number of the first guiding segments 131 is plural, the second guiding element 140 drives the first clutch element 110 to move for a plurality of strokes.

The first guiding section 131 of the first guiding element 130 is matched with the second guiding section 141 of the second guiding element 140, so that the first clutch element 110 can be ensured to stably perform axial displacement, and specific displacement of each section of the first clutch element 110 can be limited, namely, the dimension of one first guiding section 131 in the height direction is the displacement of the first clutch element 110 for one axial movement, so that the axial displacement of the first clutch element 110 is controlled by reasonably designing the structures of the guiding sections of the first guiding element 130 and the second guiding element 140.

In this embodiment, the second guide section 141 is defined to include a second guide surface 1410 and a second stop surface 1411, and in particular, the second stop surface 1411 is connected to the second guide surface 1410, such that when the second guide section 141 of the second guide member 140 moves along the first guide section 131 of the first guide member 130, the second guide surface 1410 moves along the first guide surface 1310, thereby ensuring effective sliding between the first guide member 130 and the second guide member 140, and such that when the second guide member 140 moves to the first stop surface 1311, the second stop surface 1411 contacts the first stop surface 1311 to achieve a stop engagement between the first guide member 130 and the second guide member 140, facilitating control of axial displacement of the first clutch member 110.

Specifically, the inner circumference of the fixing member 120 is formed with a plurality of connected first guide sections 131, the outer circumferential wall of the first clutch member 110 is formed with a plurality of connected second guide sections 141, specifically, the first guide sections 131 include a first guide surface 1310 and a first limiting surface 1311, the first guide surface 1310 extends obliquely upward along the inner circumferential wall of the fixing member 120, and the first limiting surface 1311 extends horizontally along the inner circumferential wall of the fixing member 120, so that the first guide member 130 is formed in a plurality of zigzag shapes connected end to end.
