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.

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, a pushing piece and a transmission body. The transmission body comprises a 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 input torque to be supplied to the pushing piece. The pushing piece is provided with a first induction part and a second induction part which are arranged at an interval. The automatic door opening device also comprises a sensing mechanism, and a control device electrically connected with the sensing mechanism and the driving source component. The sensing mechanism, the first induction part and the second induction part are configured as follows: when a door body is closed, the sensing mechanism contacts with the first induction part; when the door body is opened, the sensing mechanism contacts with the second induction part; the control device controls the driving source component to drive the pushing piece to extend out or return according to the matching state between the sensing mechanism and the first induction part and the second induction part.

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 ...
