Refrigerator with food vacuum pre-cooling chamber

Abstract

The invention provides a refrigerator with a food vacuum pre-cooling chamber. The refrigerator is internally provided with a vacuum pre-cooling chamber, and the vacuum pre-cooling room and a refrigerating chamber are relatively independent and sealed; a compressor compartment is internally provided with a vacuum pump of which an air inlet is connected to an air extraction pipe, and the other end of the air extraction pipe communicates with the vacuum pre-cooling chamber; the air extraction pipe is provided with a check valve; the vacuum pre-cooling chamber is internally provided with a pressure sensor used for measuring a pressure value in the vacuum pre-cooling chamber in real time and feeding back the pressure value to a main control panel of the refrigerator; and the vacuum pre-cooling chamber is also provided with an exhaust valve, and the top of the vacuum pre-cooling chamber is provided with a vapor condenser of which the bottom is connected to a drainage device. The refrigerator provided by the invention has the advantages of novel structure, rational design and high practicability, and the respiration intensity of food, especially fruits and vegetables, can be reduced greatly; and the shelf life of the food is prolonged, and the energy consumption of the refrigerator is reduced.

Description

technical field

[0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator provided with a food vacuum pre-cooling chamber. Background technique

[0002] Refrigerators have become an indispensable household appliance for millions of households, and one of the important links for fresh food to go from the place of production to the dining table. Therefore, users pay more and more attention to the fresh-keeping function of refrigerators. The study found that storage temperature and cooling rate are particularly important for the storage of fresh food. The faster the fresh food can be brought to the target temperature, the better its quality will be preserved.

[0003] Many times, especially in summer, users put the purchased food directly in the refrigerator. Due to the large temperature difference between the inside and outside of the refrigerator, the newly put food in the refrigerator will cause the local temperature of the refri...
