Refrigerator

Abstract

The invention discloses a refrigerator. The refrigerator comprises a refrigeration chamber, and a circulating air way for supplying cooling capacity to the refrigeration chamber, wherein the refrigeration chamber is encircled by a first liner and a door body. The refrigerator further comprises a second liner surrounding the outer side of the first liner; openings of the first liner and the second liner are tightly connected; the first liner and the second liner are encircled to form a cavity surrounding the outer side of the first liner; and the second liner is provided with an air inlet communicated with the circulating air way for entering cold air into the cavity and an air return port communicated with the circulating air way for entering the air in the cavity into the circulating air way. The cold air in the cavity performs the heat exchange with the refrigeration chamber through five liner walls of the first liner, so that the refrigeration chamber is synchronously and uniformly refrigerated from five surfaces to achieve effects of improving the heat exchange efficiency and reducing the energy consumption; and meanwhile, the cold air is not directly contacted with foods in the refrigeration chamber to achieve such beneficial effects as difficult food airing, difficult frost damage and difficult tainting by order among all refrigeration chambers.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to an air-cooled refrigerator with a structure for indirectly cooling a refrigeration compartment. Background technique [0002] At present, existing refrigerators are generally divided into two categories: air-cooled refrigerators and direct-cooled refrigerators. The cooling method of air-cooled refrigerators is usually refrigerated by the evaporator, and then the cold air is distributed to each refrigeration room through the air duct system. Air-drying will affect the freshness preservation effect; (2) the food in each refrigeration room is easy to smell; (3) the evaporator is easy to frost, and needs to be heated to defrost, which consumes a lot of power and the defrosting water is not easy to handle. [0003] The cooling method of the direct cooling refrigerator is that the cooling capacity generated by the evaporator directly cools the refrigerating room, and the evaporator is ins...

Problems solved by technology

The cooling method of air-cooled refrigerators is usually refrigerated by the evaporator, and then the cold air is distributed to each refrigeration room through the air duct system. Air drying will affect the freshness preservation effect; (2) the food in each refrigeration room is easy to smell; (3) the evaporator is easy to frost, and needs to be heated to defrost, which consumes a lot of power and the defrosting water is not easy to handle

[0003] The cooling method of the direct cooling refrigerator is that the cooling capacity generated by the evaporator directly cools the refrigerating room, and the evaporator is installed inside or outside the refrigerating room, which will have the following disadvantages: (1) It is easy for the items in the refrigerating room to be close to the inner wall It was damaged by freezing; (2) When deicing, it is necessary to cut off the power to deicing, the operation is cumbersome, and it is not good for the compressor
