Example 1

The present invention provides a door-opening structure for a mini washing machine, as shown in FIGS. 300 includes:

The connecting piece 210 is a shell structure, and is arranged on the laundry component 200 of the washing machine body 1;

At least two connecting rods are rotatably connected to one side of the connecting member 210 to form a rotating structure of the door opening assembly 300 for opening the door body 100;

The connecting member 210 is provided with an elastic member 340 for being stretched to generate resilience when the door body 100 is closed; the elastic member 340 is connected to at least one of the connecting rods; when the door body 100 is unlocked, The resilient force drives the connecting rod to rotate to drive the door body 100 to open and close. When the door body 100 is closed, the elastic member 340 is in a stressed state under the closing force of the door body; when the closing force of the door body 100 is removed, the elastic member 340 rebounds, causing the connecting rod to rotate, thereby driving the door body 100 to turn over. The elastic member has a simple structure, and realizes automatic opening of the door body 100 by utilizing its own deformation ability. The overall size of the washing machine body 1 is small, and is used for washing small-sized items such as underwear and socks. The inner cylinder can be used to process 0.5-3.5K _g dry clothes, preferably 0.5-1.5K _g dry clothes. Therefore, the door body 100 is small in size and light in weight. Through the cooperation of the connecting rod and the elastic member 340, the door can be opened automatically.

In one embodiment, as shown in FIG. 2 , the elastic member 340 includes a torsion spring and is sheathed on at least one of the connecting rods. One end of the torsion spring is fixed on the connecting member 210, and the other end is fixed on the connecting rod. When the door body 100 is closed, the door body 100 makes the torsion spring in a stressed state through the connecting rod; when the closing force of the door body 100 is removed, the tensile force exerted by the door body 100 on the torsion spring through the connecting rod is removed, and the torsion spring resets, making the door body 100 opens.

In one embodiment, as shown in FIG. 2 , the door opening assembly 300 further includes a damping element 350 for relieving the elastic force of the elastic element 340 so as to prevent the elastic element from recovering too quickly and causing damage to the door body 100 .

In one embodiment, as shown in Fig. 2 and Fig. 3, the number of connecting rods provided on one side of the connecting member 210 is two; The member 340, the damping member 350; the elastic member 340, the damping member 350 are sequentially arranged along the opening movement direction of the door body 100. The force to automatically open the door body 100 is provided by the elastic member 340 , and the rebound force of the elastic member 340 is buffered by the damping member 350 , so that the door body 100 can be automatically and slowly opened. The elastic member 340 and the damping member 350 are sequentially arranged along the opening and moving direction of the door body 100, that is, the connecting rod on which the elastic member 340 is sleeved and the connecting member 210 are connected by rotation, and the center of gravity of the door body 100 is relatively close. The force required to rotate the connecting rod to drive the door body 100 to turn over is relatively small, and the elastic member 340 is sheathed on the connecting rod to reduce the requirement on the resilience of the elastic member 340 .

In one embodiment, as shown in FIG. 4 and FIG. 6 , the other ends of the two connecting rods are respectively rotatably connected to two different hinge points on one side of the door body 100 to form a secondary connecting rod structure. That is, one end of the two connecting rods is respectively connected to two different hinge points on the door shell 220 of the washing machine body 1, and the other end is respectively connected to two different hinge points on one side of the door body 100; When the external force drives the door body 100 to open, the door body 100 rotates around the door shell under the traction of the two connecting rods. At least two connecting rods form a connecting rod structure, and cooperate with the door body 100 to form a multi-link transmission mechanism. Driven by external force, the multi-link transmission mechanism makes the connecting rod structure rotate, and the connecting rod structure Rotate to drive the door body 100 to turn over and open. The multi-link transmission mechanism has stable transmission, simple structure, and the motion trajectory can be designed according to requirements. When the door body 100 is opened, the resilient force of the elastic member 340 makes the two connecting rods rotate relative to the laundry assembly 200 , driving the door body 100 to turn over. When the elastic member 340 is reset, the door body 100 is opened, and the user can manually turn over the door body 100 as required, and the door body 100 can rotate relative to the connecting rod structure, further opening the storage opening of the laundry assembly 200 .

Further, the first connecting rod 311 and the third connecting rod 312 are opposite to each other, and are respectively rotatably connected to the connecting member 210, the second connecting rod 321 and the fourth connecting rod 322 are opposite to each other, and Rotately connected to the connecting piece 210 respectively; the first connecting rod 311, the connecting piece 210, and the third connecting rod 312 jointly form a U-shaped structure, and the second connecting rod 321, the connecting piece 210. The fourth connecting rod 322 together forms a U-shaped structure, which facilitates the design and assembly of the connecting rod structure. When the door body 100 is overturned, the movement tracks of the first link 311 and the third link 312 relative to the link 210 are symmetrical, and the second link 321 and the fourth link 322 are opposite to the link 210 The motion trajectory is symmetrical.
