Automatic clutch door opener and refrigerator

Abstract

The invention provides an automatic clutch door opener and a refrigerator. The automatic clutch door opener comprises a base, a drive source, a first push rod, a second push rod and a transmission assembly, wherein the first push rod and the second push rod are movably arranged on the base; the transmission assembly comprises a center shaft, a driving wheel, a first driven wheel, a second driven wheel, a guiding wheel, first linkage gears and second linkage gears; the driving wheel, the first driven wheel, the second driven wheel, the guiding wheel, the first linkage gears and the second linkage gears are arranged on the center shaft in a sleeving way; sliding chutes are formed in the guiding wheel and are provided with first meshing flanges adaptive to the first linkage gears and second meshing flanges adaptive to the second linkage gears; and the first linkage gears and the second linkage gears move along the sliding chutes, so that the transformation of a coordination state of the driving wheel and the first driven wheel or the second driven wheel can be realized. According to the automatic clutch door opener, the drive source drives the driving wheel to rotate along different directions, so that two door bodies are automatically opened; and the automatic clutch door opener is reasonable in structure and reliable to work, so that 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 volumes are increasingly favored and recognized by the market. However, such refrigerators with larger volumes have heavier doors and greater suction power of the door seals. There is a type of electric door opening device disclosed in the industry, but the torque output by the motor is high, the installation position is limited, and the noise is large, which affects the user experience. [0003] The initial stage of the refrigerator door opening process requires sufficient force to overcome the suction force of the door seal, and the subsequent movement of the door only needs to overcome the automatic closing locking force and friction of the hinge. Correspondingly, the required action during the subsequent m...

Problems solved by technology

On the other hand, multi-door refrigerators need to be equipped with multiple sets of automatic door opening devices, which increases the cost and difficulty of assembly

In view of this, the industry also discloses a double door opening mechanism, which realizes the automatic opening of the left and right doors through different pushers, but its structure still needs further optimization and improvement
