When the drawer body 20 is located in the accommodating cavity 11 and the latch assembly 70 is in the unlocked state, the first elastic member 82 can drive the rotating shaft 83 to rotate so as to drive the pushing member 85 to move so as to push the drawer body 20 out of the accommodating cavity 11.

In order to more clearly describe the structure of the damping mechanism 80, the damping mechanism 80 will be described with reference to the drawings.

For example, referring to fig. 8, in order to better push the drawer body 20 out of the outer casing 10, the damping mechanisms 80 may be arranged in two sets, wherein the outer casing 10 includes a first side wall 15 and a second side wall 16, the damping mechanisms 80 may be arranged on the first side wall 15, and the damping mechanisms may be arranged on the second side wall 16.

Illustratively, with continued reference to fig. 7 and 8, a guide slot 17 is provided in the outer housing 10, and the pushing member 85 is slidably disposed in the guide slot 17 to facilitate the movement of the pushing member 85. In the embodiment of the present application, the pushing member 85 is disposed outside the outer casing 10, wherein the pushing member 85 may include a pushing member body 851 and a pushing portion 852 disposed at one end of the pushing member body 851, the body of the pushing member 85 is slidably disposed in the guide groove 17 and is in meshing connection with the gear 84, and in order to enable the pushing member 85 to push the drawer body 20, a clearance groove 18 capable of allowing the pushing portion 852 to extend into the accommodating cavity 11 may be disposed on a sidewall of the outer casing 10, so that the pushing portion 852 can abut on the drawer body 20 to push the drawer body 20. Of course, if the damping mechanism 80 is provided in the outer case 10, the clearance groove 18 need not be provided. In the present embodiment, the pushing portion 852 abuts against the rear end of the drawer body 20, and it can be understood that the rear end of the drawer body 20 is the end of the drawer body 20 facing the back of the washing machine 1 when it faces the front of the washing machine 1.

It will be appreciated that the movement of the pushing member 85 in the direction away from the accommodating chamber 11 is driven by the elastic force of the first elastic member 82. For example, referring to fig. 9, the first elastic member 82 may be a spring wound around the shaft 83 and disposed in the mounting cavity of the damping housing 81, an inner end of the spring is fixedly connected to a first end of the shaft 83, an outer end of the spring is fixedly connected to the damping housing 81, and the wound spring can provide an elastic force for driving the shaft 83 to rotate. It will be understood that the inner end of the spring refers to the end located in the centre of winding and the outer end of the spring refers to the end located outermost.

Illustratively, the spring can be wound to be elastically deformed when the rotation shaft 83 rotates in a clockwise direction, and the rotation shaft 83 can be driven to rotate in a counterclockwise direction when the spring recovers the elastic deformation. In the embodiment of the present application, when the drawer body 20 is in the pulled-out state, during the process of pushing the drawer body 20 into the accommodating cavity 11 of the outer housing 10, the drawer body 20 can drive the pushing member 85 to move toward the accommodating cavity 11, at this time, under the transmission of the gear 84, the rotating shaft 83 rotates to wind up the spring to generate elastic deformation and store elastic potential energy, after the drawer body 20 is accommodated in the accommodating cavity 11 of the outer housing 10, the locking assembly 70 locks the relative sliding between the drawer body 20 and the outer housing 10, at this time, due to the locking action of the locking assembly 70, the elastic potential energy of the spring is insufficient to drive the pushing member 85 to push the drawer body 20 out of the accommodating cavity 11 of the outer housing 10, and the drawer body 20 remains in the state in the outer housing 10. When the locking of the locking assembly 70 is released, the spring returns to elastic deformation and drives the rotating shaft 83 to rotate, so that the pushing member 85 can push the drawer body 20 out of the accommodating cavity 11 of the outer shell 10 under the transmission of the gear 84. Through the elasticity effect of clockwork spring, the user need exert force when can effectual reduction pull drawer body 20, has improved user experience and has felt.

For example, referring to fig. 7 and 8, in order to improve the rotational stability of the rotating shaft 83, a seat 86 may be disposed on the outer casing 10, and one end of the rotating shaft 83, which is provided with the gear 84, extends into the seat 86 and is rotatably connected with the seat 86. Under the mutual cooperation of the seat body 86 and the damping shell 81, the rotating shaft 83 can be more stable in the rotating process. In conjunction with fig. 3, an outer cover 87 may be further disposed on the damping housing 81, the rotating shaft 83, the gear 84, the pushing member 85, and the outer cover 87 of the seat body 86, so as to achieve the dustproof and protective effects.

To more clearly illustrate the construction of the latch assembly 70, the latch assembly 70 will be described with reference to the drawings.

When the hook 722 is in the retracted state, the wall of the locking chamber 711 limits the first and second pawls 7221 and 7222 from moving away from each other so that the first and second pawls 7221 and 7222 can lock the locking hook 73, thereby locking the relative sliding movement between the drawer body 20 and the outer housing 10.

For example, referring to fig. 10 and 11, in order to facilitate the control of unlocking and locking between the latch 72 and the latch hook 73, the latch assembly 70 may further include a second elastic member 74 and an elastic hook 75, the latch body 721 is provided with a clamping portion 723 and a guide portion 724, the clamping portion 723 has a clamping surface 7231 and a first guide surface 7232 connected to the clamping surface 7231, the guide portion 724 has a second guide surface 7241, and the second guide surface 7241 is opposite to the clamping surface 7231. Wherein, the first end of the elastic hook 75 is fixedly arranged on the latch shell 71, the second end of the elastic hook 75 can be clamped on the clamping surface 7231, and when the second end of the elastic hook 75 is clamped on the clamping surface 7231, the clamping hook 722 keeps the retraction state and fastens the latch hook 73. The first end of the second elastic element 74 is fixedly connected to the locking housing 71, and the second end of the second elastic element 74 is fixedly connected to the locking body 721, wherein when the second end of the elastic hook 75 is separated from the locking surface 7231, the second elastic element 74 can push the locking body 721 to extend the hook 722 out of the locking cavity 711.

As shown in fig. 10, when the hook 722 is in the retracted state, the second end of the elastic hook 75 is engaged with the engaging surface 7231 to maintain the retracted state of the hook 722, and at this time, the second elastic element 74 is in the elastic deformation state. When the hook 722 is in the retracted state, an external force is applied to the hook 722 toward the inside of the locking cavity 711, as shown in fig. 11, the second end of the elastic hook 75 can be separated from the locking surface 7231 and guided to the first guiding surface 7232 by the second guiding surface 7241, and when the external force is removed, the second elastic member 74 can be deformed to push the hook 722 out of the locking cavity 711. For example, the second elastic member 74 may be a cylindrical compression spring, and when the hook 722 is in the retracted state, the second end of the elastic hook 75 is engaged with the engaging surface 7231 to maintain the retracted state of the hook 722, and the cylindrical compression spring is in a compressed state. When the hook 722 is in the retracted state, an external force is applied to the hook 722 toward the inside of the locking cavity 711, the second end of the elastic hook 75 can be separated from the locking surface 7231 and guided to the first guide surface 7232 by the second guide surface 7241, and when the external force is removed, the cylindrical compression spring can be deformed to push the hook 722 out of the locking cavity 711. When the hook 722 is pushed into the latching chamber 711 again, the cylindrical compression spring is compressed, the second end of the elastic hook 75 can move from the second guide surface 7241 to the first guide surface 7232 and be caught on the catching surface 7231, and the pushing force is removed, and the retracted state of the hook 722 can be maintained since the second end of the elastic hook 75 is caught on the catching surface 7231. As shown in fig. 11, the locus of the dotted arrow in the figure is the movement locus of the second end of the elastic hook 75.

For example, as shown in fig. 11, in order to improve the stability of the lock catch body 721 during the sliding process, a guide post 712 may be disposed in the lock catch shell 71, a guide groove matched with the guide post 712 is disposed on the lock catch body 721, and the guide post 712 is slidably inserted into the guide groove, wherein a cylindrical compression spring is sleeved on the guide post 712.

It can be understood that the whole sliding process of the drawer body 20 is as follows: when the drawer body 20 is entirely accommodated in the outer housing 10, the drawer body 20 is pressed in the sliding direction of the drawer body 20, so that the second end of the elastic hook 75 of the locking assembly 70 can be separated from the clamping surface 7231, the cylindrical spring in the locking assembly 70 pushes the clamping hook 722 out of the locking cavity 711, at this time, due to the fact that the limiting effect of the wall of the locking cavity 711 is not provided, the clamping hook 722 is in an unlocking state, the damping mechanism 80 can push the drawer body 20 to move, so that the drawer body 20 is pushed out of the outer housing 10, and therefore articles on the drawer body 20 can be replaced. When the drawer body 20 is in the pushed-out state, the drawer body 20 is pushed into the outer housing 10 so that the hook 722 is fastened to the latch hook 73 until the hook 722 is retracted into the latch cavity 711 so that the hook 722 fastens the latch hook 73, and at this time, the second end of the elastic hook 75 of the latch assembly 70 is fastened to the fastening surface 7231 so that the latch assembly 70 maintains the locked state, so that the drawer body 20 is accommodated in the outer housing 10.
