Automatic door opening device and refrigerator with same

Abstract

The invention provides an automatic door opening device and a refrigerator using the same. The automatic door opening device is used for automatically opening a door body of the refrigerator, and comprises a shell, a driving component, a pushing part and a transmission component, the transmission component comprises a first gear set, a second gear set, a third gear set, a fourth gear set and a fifth gear set, wherein the third gear set comprises a first left gear; the fourth gear set comprises a second left gear, and a first one-way clutch bearing set is arranged in the second left gear; the fifth gear set comprises a third left gear, the third left gear is connected with the pushing part, and the first left gear is stacked on the second left gear, and the rotating shaft of the first leftgear enters the first one-way clutch bearing set; and when the first transmission direction of the first one-way clutch bearing set is the same as the rotation direction of the first left gear, the first left gear and the second left gear rotate coaxially, the second left gear drives the third left gear to enable the pushing part to extend out or reset from the shell.

Description

technical field [0001] The invention relates to an automatic door opening device and a refrigerator provided with the automatic door opening 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. For this problem, electric opener has occurred. [0003] In the existing electric opening device, in the process of opening the door body, the motor drives the screw to rotate forward, and the screw engages the gear assembly, and then drives the push rod to drive the door to open; when the door is opened, the motor drives the screw to reverse, and the screw The rod engages the gear assembly, which in turn drives the push rod back. The above-mentioned electric opening device uses a double-shaft m...

AI Technical Summary

Problems solved by technology

Among them, the working noise of the double-axis motor is relatively large

In addition, a rack is often designed on the push rod, and the extension and reset of the push rod are realized through the cooperation of the rack and the gear assembly, while the push rod with a rack increases the production and manufacturing costs to a certain extent, and also increases The structural complexity of the entire electric opening device
