Embodiment 1

[0040] combine Figure 1 to Figure 5 , the automatic door opening device of the present invention can be applied to any equipment that needs to be opened electrically, such as a refrigerator, and installed behind the door body of the equipment or the door body of the drawer, so as to make the door body of the equipment or the drawer on the equipment The door opens. The automatic door opening device 500 includes a base 100, a drive source component 200 fixed on the base 100, a non-circular incomplete gear-rack actuator 400 for pushing the door body, and a non-circular incomplete gear-rack actuator 400 connected between the drive source component 200 and the non-circular The transmission mechanism 300 between the circular incomplete gear and the rack actuator 400 . The automatic opening device of the present invention is used to electrically open two doors, so that two completely identical non-circular incomplete gear-rack actuators 400 are correspondingly provided.

Abstract

The invention discloses an automatic door operator and a refrigerator provided with the same. The automatic door operator comprises a base, a drive mechanism and two non-circular intermittent gear and rack actuating mechanisms for pushing door bodies, wherein the drive mechanism is fixed in the base and is used for connecting a driving source component with the non-circular intermittent gear and rack actuating mechanisms; the non-circular intermittent gear and rack actuating mechanisms are arranged in the base and comprise rack push rods for pushing the door bodies, and non-circular intermittent gears meshed with the rack push rods; when the two door bodies are in a closed state, teeth of the rack push rods are not meshed with the non-circular intermittent gears; when one door body is required to be opened, the driving source component drives the drive mechanism to rotate, thus, the non-circular intermittent gears are driven to rotate, the non-circular intermittent gears are meshed with the teeth of the rack push rods, and the rack push rods extend out of the base, and the door body is pushed to be opened. The automatic door operator has the advantages of small size, small vibration and noise, long service life and high reliability.

Description

technical field [0001] The invention belongs to the field of refrigerators, and in particular relates to an automatic door opening device and a refrigerator with the device. Background technique [0002] At present, mid-to-high-end refrigerators on the market are relatively large, and the door body, the weight of its load, and the suction force of the door body or the door seal of the drawer-type door body are relatively large. More and more users report that the refrigerator door body is not easy to open. [0003] Generally, the opening of the refrigerator door is divided into three stages. The first stage is mainly to overcome the force of door seal suction, automatic closing locking force, inertial force and door hinge friction force. This stage needs to overcome the largest force; the second stage mainly overcomes the locking force of automatic closing and hinge friction force. and other forces; the third stage needs to overcome the frictional force of the door hinge an...
