a refrigerator

Abstract

The invention discloses a refrigerator, relates to the technical field of refrigeration, and is designed to provide a refrigerator whose appearance can be guaranteed to be beautiful and whose door body can be easily and automatically opened and closed. The refrigerator includes a box body with a storage room inside and a door body arranged at the opening of the storage room. A door opening and closing device is connected between the box body and the door body. The door opening and closing device includes: a hinged plate installed on the box body , the hinge plate is connected to the door body through the hinge shaft; one end of the push rod is connected to the driving mechanism, and the other end is connected to the door body through the connecting column, and the connecting column is located on the side of the door body close to the box body, and the driving mechanism It is used to drive the push rod to move to push the door body to rotate around the hinge shaft; the guide structure is used to guide the sliding direction of the connecting column. The refrigerator of the invention is used to improve the use performance.

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 opening and closing device uses the output shaft of the motor (not shown in the figure) to drive the driving gear 002 to rotate, and the driving gear 002 drives the driven gear 003 installed o...

AI Technical Summary

Problems solved by technology

figure 1 The moment arm of the torque of the refrigerator door 001 shown is the radius L1 of the driven gear 003. Since the radius L1 is generally small, the rotational torque of the hinge shaft is small, and sometimes it is still necessary to manually open and close the refrigerator door. Refrigerator door 001 is easy to open and close, which can increase the torque arm of refrigerator door 001, and correspondingly increase the radius of driven gear 003, which will cause the edge of driven gear 003 to exceed the edge of refrigerator door 001, affecting the entire The appearance and aesthetics of the refrigerator affect the user experience
