Automatic door opening device and refrigerator with the same

Abstract

The invention discloses an automatic door opening device and a refrigerator with the same. The automatic door opening device comprises a base, a driving source component, two pushing pieces, a transmission body and a control device. The pushing pieces are provided with linear racks; the transmission body comprises a conjugated gear set and a shifting disc arranged on the output end of the conjugated gear set; the driving source component provides input torque for the conjugated gear set; the conjugated gear set converts the input torque into continuously changed output torque to be supplied to the shifting disc; the shifting disc is provided with a disc body and an arc rack arranged on the peripheral surface of the disc body; the shifting disc is configured as follows: when two door bodies are closed, the arc rack extends between the two pushing pieces; when one door body is opened, the control device controls the driving source component to drive the shifting disc to rotate in the direction of the pushing piece corresponding to the door body, and ensures that the arc rack and the linear rack of the pushing piece are in meshed transmission and the pushing pieces move.

Description

technical field [0001] The invention 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. For this problem, electric opener has occurred. [0003] In the process of opening the door, it is necessary to overcome the suction force of the door seal, the locking force of the slide rail, or the self-closing force and friction of the door body. Generally, it is mainly divided into three stages: the first stage mainly overcomes the door seal. Suction force, self-closing locking force and friction force; the second stage mainly overcomes the locking force of self-closing (such as spring tension or the self-closer structure ...

AI Technical Summary

Problems solved by technology

However, this structure does not take into account the influence of factors such as speed changes and door opening time during the drawer opening process.

Moreover, during the opening process of the drawer, the driving pins 20a, 20b, and 20c need to be in contact with the connecting plate 16 successively, and there is a discontinuous situation during the cooperation process, resulting in an uneven opening process of the drawer.
