Separation and connection automatic door opening device and refrigerator

Abstract

The invention provides a separation and connection automatic door opening device and a refrigerator. The separation and connection automatic door opening device comprises a base, a drive source, a push rod and a transmission assembly arranged between the drive source and the push rod. The push rod is movably installed on the base. The transmission assembly comprises a center shaft fixed to the base, a driving wheel, a driven wheel, a separation and connection wheel and a linkage wheel. The driving wheel and the driven wheel are arranged on the center shaft in a sleeving manner. The separationand connection wheel is arranged between the driving wheel and the driven wheel. The linkage wheel is located on the side, away from the separation and connection wheel, of the driving wheel. The separation and connection wheel and the linkage wheel are fixed to each other in the circumferential direction of the center shaft, the separation and connection wheel can move in the axial direction relative to the linkage wheel. The transmission assembly further comprises an elastic piece acting on the linkage wheel. By means of rotation, relative to the driving wheel, of the separation and connection wheel, the separation and connection wheel can move in the axial direction, conversion of the cooperative relationship of the driving wheel and the driven wheel is achieved, installation is convenient, a refrigerator door body can be easily opened, the structure is reasonable, work is more reliable, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a clutch automatic door opening device and a refrigerator. Background technique [0002] With the improvement of living standards, refrigerators with larger volume are more and more favored and recognized by the market, but such refrigerators with larger volume have larger door weight and greater door seal suction. There is a type of electric door opening device disclosed in the industry, but the torque demand of the motor output is relatively high, the installation position is limited, and the noise is relatively large, which affects the user experience. [0003] The initial stage of the door opening process of the refrigerator needs enough force to overcome the suction force of the door seal, and the subsequent movement process of the door body only needs to overcome the automatic closing locking force and friction force of the hinge. less force. In view of th...
