Abstract

The invention provides a door lock used for a refrigerator. The door lock comprises a shell body, a plunger and a limiting device. A through hole is formed in the side face of the shell body. An on-off device is arranged in the shell body and used for controlling the position of a lock needle in the shell body. The plunger is located inside the shell body, and one end of the plunger extends outside the through hole of the side face of the shell body. The plunger reciprocates in the through hole and controls the position of the lock needle through the on-off device. The limiting device is used for limiting the motion position of the plunger in the through hole. By means of the door lock, closing between a refrigerator door and the refrigerator can be more closely, and the situation that the refrigeration effect of the refrigerator is affected due to frequent door opening of the refrigerator is avoided.

Description

technical field [0001] The invention belongs to the technical field of household appliance accessories, in particular to a door lock for a refrigerator. Background technique [0002] A refrigerator is a kind of refrigeration equipment that keeps a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. At present, 91-95% of the refrigerators in the world are compression refrigerators. At present, the vast majority of household refrigerators are refrigerated by the principle of vapor compression refrigeration cycle, that is, the compressor is used to increase the pressure of the refrigerant, so that the refrigerant circulates in the refrigeration system cycle, and the back and forth conversion of gasification and liquefaction, In this way, the heat in the refrigerated and frozen food in the box is "moved out" outside the box repeatedly, so as to realize the cooling purpose. The refrigerator con...
