Air-cooled refrigerator and humidifying and freshness keeping method

Abstract

The invention discloses an air-cooled refrigerator. The air-cooled refrigerator is provided with a box which comprises a shell and a liner; the liner is arranged in the shell, and the space between the liner and the shell is filled with a heat preserving layer; and the liner is sequentially provided with a cold storage chamber, a temperature changing chamber and a freezing chamber from top to bottom. On the interior of the rear side of the freezing chamber, the heat preserving layer is provided with a cold air cavity for containing an evaporator and a draught fan. The cold air cavity is communicated with the freezing chamber through a first air feeding air duct which is located on an air outlet of the inner wall of the freezing chamber, and a freezing air door is arranged. The cold air cavity is communicated with the temperature changing chamber through a second air feeding air duct which is located on an air outlet of the inner wall of the temperature changing chamber, and a temperature changing air door is arranged. The cold air cavity is communicated with the cold storage chamber through a third air feeding air duct which is located on an air outlet of the inner wall of the cold storage chamber, and a cold storage air door is arranged. The invention further discloses a humidifying and freshness keeping method. The air-cooled refrigerator is reasonable in structure, accurate in humidity control and high in practicability, water in the air-cooled refrigerator is kept conserved, and frosting is effectively prevented.

Description

technical field

[0001] The invention relates to the technical field of household appliances, in particular to an air-cooled refrigerator and a humidifying and fresh-keeping method. Background technique

[0002] The refrigerating room, variable temperature room and freezing room of the existing air-cooled refrigerator generally use circulating air to pass through the evaporator to lower the temperature, and then the fan sends the cold air to the refrigerating room for cooling. Although this forced cooling method has a fast cooling speed, each The advantages of uniform temperature, but because the circulating air needs to pass through the evaporator for heat exchange and cooling, the water contained in it is analyzed and condensed on the evaporator, so that the air humidity in the refrigerator is low, and the food stored in the refrigerator is air-dried , so that food loses moisture. The cooling method of the air-cooled refrigerator refrigerator is to blow cold air into the r...
