Refrigerator

Abstract

The invention discloses a refrigerator, relates to the technical field of refrigeration. A door opening and closing device is provided for driving an ejection mechanism and a rotating mechanism to actonly through one driving motor, and the rotating mechanism is locked when the driving motor drives the ejection mechanism to act through one clutch. The refrigerator comprises a refrigerator body provided with a storage chamber and a door body arranged at an opening of the storage chamber, wherein the door body is rotationally connected with the refrigerator body through a hinge shaft, the refrigerator further comprises the door opening and closing device, the door opening and closing device comprises the ejection mechanism and the rotating mechanism, the ejection mechanism and the rotating mechanism are driven by the same driving mechanism, the driving mechanism is used for driving the ejection mechanism to move so as to eject the door body open and used for driving the rotating mechanism to move so as to drive the door body to rotate around the hinge shaft, the driving mechanism comprises one driving motor, one clutch is arranged between the output end of the driving mechanism and the rotating mechanism, and the clutch is used for connecting or disconnecting the output of the driving mechanism and the rotating mechanism. The use performance of the refrigerator is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator. Background technique [0002] With the improvement of residents' living standards, refrigerators have become a must-have household appliance. The volume of refrigerators has also begun to expand, and the doors of refrigerators have become heavier and heavier. The weight of refrigerator doors will make it difficult for people to open them, especially for the elderly. How to open the door easily has become a big problem for many consumers and refrigerator manufacturers. [0003] Refrigerators in the prior art adopt door opening and closing devices to realize the automatic opening and automatic closing of the refrigerator door body, refer to figure 1 At present, the door switch device includes a first door switch device 03 and a second door switch device 04 arranged between the box body 01 and the door body 02, and the first door switch device 03 is close to t...

AI Technical Summary

Problems solved by technology

However, this door opening and closing device realizes the automatic opening and closing of the door body 02 through two sets of separated actuators (ejection structure+rotation structure). The technical problems in this prior art are: first, two driving motors are required to drive The ejection mechanism and the rotation mechanism move, which also causes the structure of the whole door opening and closing device to be complicated, and will increase the manufacturing cost accordingly; second, when opening the door, it is necessary to first control the drive motor for controlling the ejection mechanism to start, and then control the drive motor used to control the ejection mechanism. Control the drive motor of the rotating mechanism to start, so that the ejector mechanism first pushes the door open, and then uses the rotating mechanism to drive the door to rotate around the hinge axis, which makes the control complicated
