Small refrigerating device with copious cooling function

Abstract

A small refrigerating device with a copious cooling function comprises a refrigerating circulation loop which is formed by a main machine, a condenser, a dry filter, a capillary, an evaporator group, an air-returning tube and a liquid storer. A tank body is provided with a controller assembly, temperature areas and a temperature sensor. The evaporator group comprises at least two evaporators which are serially arranged, and each evaporator corresponds to different temperature areas. The capillary is closely attached onto the air-returning tube and performs heat exchanging with the air-returning tube, a bi-stable state solenoid valve is respectively arranged between the capillary and the evaporators and between the two evaporators, and a unidirectional solenoid valve is connected onto each evaporator in parallel mode. The temperature sensor, the bi-stable state solenoid valve and the unidirectional solenoid valve are all connected onto the controller assembly. The small refrigerating device well solves the problems that an existing household small refrigerating device is short in freezing preservation time, leads nutrition constituent to run off and does not have functions of copious preservation and copious drying.

Description

technical field [0001] The invention relates to a refrigeration device with multiple temperature zones, which can realize the temperature adjustment of each temperature zone and form multiple combined energy-saving operation modes, including freezers, refrigerators, display cabinets, medical storage cabinets (boxes), and biological product storage cabinets. (box) and small cold storage, etc. Background technique [0002] After the world's first quick-frozen food machine was successfully trial-produced in the United States in 1920, quick-frozen food was applied because of its simplicity and low cost. China's quick-frozen food started in the 1980s and has become the most competitive field in the food industry. Making and freezing and preserving quick-frozen foods at home mainly rely on small refrigeration devices such as freezers and refrigerators. [0003] Cryopreservation of quick-frozen food is the food that needs to be quick-frozen, such as vegetable raw materials, meat,...

Problems solved by technology

[0007] At present, the research on cryogenic household refrigeration equipment in my country is almost blank, and foreign brands have always occupied a dominant position. Only a few countries in the world, such as Japan, the United States, Germany, and Denmark, can produce household refrigeration equipment in the low-temperature field of -140°C to -150°C. its very expensive
