Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises a storage room defined by a refrigerator container, a second air curtain air duct arranged on the top wall of the refrigerator container and provided with an air curtain air outlet in the front end, a fan accommodating cavity arranged on the rear wall of the refrigerator container and used for accommodating a centrifugal fan, a first air curtain duct and a main air supply duct, the first air curtain duct extends to the top end of the refrigerator liner from bottom to top, the lower end of the first air curtain duct communicates with the fan accommodating cavity through an air curtain air inlet, and the upper end of the first air curtain duct communicates with a second air curtain duct; one end of the main air supply duct communicates with the fan accommodating cavity through a main air inlet, and the other end of the main air supply duct communicates with the storage room; when the storage room is closed, the air curtain air inlet is closed, and the main air inlet is opened; and when the storage room is opened, the air curtain air inlet is opened, and the main air inlet is closed. Different air ducts are opened according to the opening and closing states of the storage room, on one hand, air curtain air outlet in the door opening stage of the refrigerator storage room can be achieved, and therefore loss of the cooling capacity of the storage room and heat exchange inside and outside the storage room are effectively blocked; and on the other hand, the main air inlet is closed in the door opening stage of the storage room, and resources can be effectively saved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerator. Background technique [0002] As an indispensable electrical product in home life, refrigerators occupy an important market share. With the improvement of consumers' requirements for the quality of fresh food, the requirements for refrigerators are also getting higher and higher, and refrigerators are required to have higher configuration and more powerful functions. Air curtain, also known as air curtain, is mainly used above the entrances of shopping malls, theaters, hotels, restaurants, etc. for refrigeration, air conditioning, dustproof, and heat insulation. It can isolate indoor and outdoor air and prevent indoor and outdoor air from exchanging heat and cold. Anti-dust, anti-pollution, anti-mosquito and fly. [0003] For air-cooled refrigerator products, according to the existing test: when the ambient temperature is 30°C, if the door of t...

AI Technical Summary

Problems solved by technology

At present, there is a large amount of cold loss in the refrigerator when the door is opened. The opening stage of the refrigerator will not only bring huge temperature fluctuations to the room, affect the freshness of the ingredients, but also increase the power consumption of the refrigerator accordingly.
