Refrigerator with unfreezing and heat insulation functions

Abstract

The invention discloses a refrigerator with heat insulation and unfreezing functions. The refrigerator comprises a freezing chamber, a refrigerating chamber, an unfreezing and heat insulation chamber, a condenser and a control device, wherein the condenser comprises a lower coiled pipe, a first metal hose, an upper coiled pipe, a second metal hose and a condensing pipe; the upper coiled pipe can be horizontally placed or vertically placed through manual operation; the unfreezing and heat insulation chamber comprises a water groove provided with a water pump, a water sprinkler, a support, a vertical fixing mechanism and a second fan; the vertical fixing mechanism is installed at a rear side of an inner cavity of the unfreezing and heat insulation chamber, and used for fixing a position of the upper coiled pipe while being vertically placed; and the control device comprises a setting module, a control module and a third temperature sensor. The refrigerator disclosed by the invention is simple in structure and convenient to install; and the refrigerator carries out food unfreezing through adopting different unfreezing modes, so that heat dissipation of the condenser of the refrigerator can be effectively reduced, and no spoilage of foods due to a too high temperature or long-time placement because of forgetting can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator with functions of thawing and heat preservation. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a product that keeps food at a constant low temperature and cold state. The refrigeration circuit of a refrigerator generally includes compressors, condensers, capillary tubes, evaporators and other components. The condenser is used for heat dissipation, and its heat dissipation performance has a great impact on the refrigeration cycle of the refrigerator. When the temperature of the condenser is too high, the compressor needs to consume more The existing technology usually reduces the ambient temperature by accelerating the heat dissipation of the condenser, and few technologies utilize the heat dissipation and waste heat recovery of the refrigerator condenser at the same time.

AI Technical Summary

Problems solved by technology

Although this patent makes good use of the waste heat condensed by the refrigerator to heat the thawed food, the thawing method is relatively simple and can only be thawed by air heating, and because the condenser is arranged on the outer wall of the thawing tank, and the temperature and temperature of the thawing chamber are controlled by a solenoid valve. Food thawing, the condenser on the thawing chamber is not continuous, resulting in low exchange efficiency between the heat of the condenser and the cooling capacity of the thawed food. In addition, during the thawing process of frozen food, the humidity in the environment is very critical to the quality of the thawed food. The patent does not involve the control technology of humidity, nor does it involve the reminder system of the defrosting state of food
