Refrigerator

Abstract

The invention discloses a refrigerator which comprises a box body, a semiconductor module, an evaporator and a second flue; the box body defines at least one refrigerating room; one side of the at least one refrigerating room is equipped with a first flue which is in fluidic communication with the refrigerating room; the semiconductor module is arranged in the box body and is used for providing cooling capacity to at the least one refrigerating room; the semiconductor module is provided with a cold end and a hot end; the cold end is positioned in the first flue; the evaporator is arranged in an evaporator cavity of the box body, so that the hot end can be cooled; the second flue is independently arranged relative to the first flue; the hot end is positioned in the second flue; the second flue comprises an air inlet path and an air return path; and cold air flows to the hot end from the evaporator through the air inlet path, and is then returned into the evaporator through the air return path. The refrigerator provided by the invention is relatively low in cost, and the refrigerating room can realize a constant-temperature constant-humidity (high-humidity) function.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a refrigerator. Background technique [0002] In the prior art, refrigerators generally refer to single-door, double-door, double-temperature, three-door, three-temperature, and cabinet-type multi-door refrigerators, which generally have an independent freezer and outer door of the freezer, so that they can be separated according to different storage temperatures. store. The refrigeration principle of this refrigerator-freezer is divided into direct cooling and air cooling. Direct-cooling refrigeration systems often use solenoid valves to control the flow of refrigerant, and supply refrigerant to the evaporators of each refrigerating (freezing) room to cool each space to the required temperature. Air-cooled refrigerators and freezers need to set up corresponding air ducts to supply air to each space. [0003] With the improvement of people's living standards, people put for...

AI Technical Summary

Problems solved by technology

[0003] With the improvement of people's living standards, people put forward higher requirements for refrigerators, such as: to make refrigerators more suitable for cold storage of various foods, because the preservation of food (such as vegetables, fruits, etc.) is quite sensitive to temperature fluctuations , especially for food preservation in the refrigerated temperature zone, temperature fluctuations will drive humidity changes, and the water evaporated from the food will continue to be lost in the form of refrigerated condensation water, which will greatly shorten the food preservation cycle

Therefore, it is necessary for the refrigerator to have constant temperature and constant humidity (high humidity) functions. However, no matter it is a direct-cooled or air-cooled refrigerator, the relative humidity of the refrigerator is relatively low, and the temperature fluctuates greatly. The control system can reduce the temperature fluctuation of the refrigerator, but the temperature fluctuation is not in the ideal range, and the cost of the inverter compressor and the inverter control system is very high
