Detailed ways

The utility model will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, this embodiment does not limit the present utility model, and any structural, method, or functional changes made by those skilled in the art according to this embodiment are included in the protection scope of the present utility model.

As shown in FIG. 1 , it is a schematic structural diagram of a refrigerator 100 of the present invention. The refrigerator 100 includes a box body 1 and a door body 2 , and an automatic door opening and closing device 3 is provided between the box body 1 and the door body 2 . The automatic door opening and closing device 3 includes a bidirectional motor (not shown) arranged on the door body 2, a control module 4 that is connected to the bidirectional motor through a circuit and controls the running direction and start/stop of the bidirectional motor, and the The transmission mechanism 5 connected with the bidirectional motor. The transmission mechanism 5 includes a gear 6 cooperating with the bidirectional motor and a hinge 7 , and the hinge 7 includes a rack 8 meshing with the gear 6 .

Referring to Fig. 1 to Fig. 2, the bidirectional motor is arranged on the side where the door body 2 and the box body 1 are rotatably connected. The gear 6 and the two-way motor are arranged on the same side of the door body 2, one end of the hinge 7 is fixed on the box body 1, and the other end extends in an arc to the door body 2 and passes through the rack with the gear 6 8 meshed.

The automatic door opening and closing device 3 is also provided with a detection device (not shown) connected to the control module 4 to monitor the position of the door body 2 .
