A thermostat for a refrigerator

Abstract

The invention discloses a temperature controller for a refrigerator, which comprises a casing and a temperature sensing tube installed on the casing. The casing is provided with a first rotating shaft, and the side walls on both sides of the first rotating shaft are provided with locking blocks. , the top of the first rotating shaft is provided with a rotating disk, the rotating disk is located above the housing, the housing is provided with a first support plate and a second support plate, the first support plate is located above the second support plate, and the first support plate A rotating piece and a plurality of resistors are provided, a first through hole is opened on the rotating piece, a first groove is opened on the side wall of the first through hole, the first through hole is matched with the first rotating shaft, and the first groove is connected with the card The block cooperates, and the side wall of the rotating piece is provided with a first contact. The invention can realize the control of the working power of the compressor by providing the rotating piece and a plurality of resistors on the first support plate, so that the refrigerator can work quickly and slowly, with high work efficiency, saving electric energy, and can be compatible with temperature sensing The tube and the spiral temperature sensing plate are linked to realize the adjustment of the cooling speed at different temperatures.

Description

technical field [0001] The invention relates to the technical field of refrigerator manufacturing, in particular to a temperature controller for a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains 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. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. The volume of household refrigerators is usually 20 to 500 liters. In 1910, the world’s first household refrigerator with compression refrigeration came out in the United States; in 1925, Lido Company of Sweden developed a household absorption refrigerator; Fully enclosed refrigerators were released, and China began to produce refrigerators in the 1950s. With the development of cities, the demand for refrigerators is also gradually increasing. Refrigerators are gradually being...
