Problems solved by technology

The first problem: During the process of opening the door, the door body may be resisted. For example, the user manually pushes the door body back. The resistance on the door body is an additional impact force on the motor. This additional impact force may cause damage to the motor.
The second problem is that in the process of opening the door, if the refrigerator suddenly loses power, the user needs to overcome the transmission force between the motor and the transmission mechanism of the automatic door opener to close the door. This large closing force is also an extra impact on the motor. force, which may also cause damage to the motor

Abstract

The invention provides a door body driving device and a refrigerator. The door body driving device is used for driving a door body of equipment and comprises a driving mechanism for driving the door body to move, wherein a bidirectional clutch gear set is arranged in the driving mechanism; when the equipment is powered off or the door body is stressed, the bidirectional clutch gear set is in a slipping state. The door body driving device can prevent acting force applied to the door body by a user from being changed into impact force on a motor, so that the possibility of damage to the motor isreduced, and the service lives of the motor and the door body driving device are prolonged.

Description

technical field [0001] The invention relates to a door body driving device for driving the door body to open and close. The invention also relates to a refrigerator, which belongs to the technical field of household equipment and refrigeration. Background technique [0002] At present, the medium and high-end refrigerators in the market are relatively large in size, and the weight of the door body and drawer load and the suction force of the door body door seal are relatively large. More and more users report that the refrigerator door body is not easy to open, especially the refrigerator drawer body. For this problem, there has been an automatic door opener, which can automatically open the door body. [0003] There are two problems in existing automatic door opener. The first problem: During the process of opening the door, the door body may be resisted. For example, the user manually pushes back the door body. The resistance received by the door body is an additional imp...
