Air-cooled refrigerator

Abstract

The invention provides an air-cooled refrigerator. The air-cooled refrigerator comprises a cold storage chamber, a freezing chamber, a temperature changing chamber and a cold storage chamber door foropening and closing the cold storage chamber. An ice-making chamber is arranged on the cold storage chamber door, the air-cooled refrigerator also comprises an ice-making air return duct, which comprises: an air inlet, which is communicated with the ice-making chamber; a first air outlet, which is communicated with the temperature changing chamber; a second air outlet, which is communicated with the freezing chamber; and a double-opening air door that is arranged in the ice-making air return duct and used for selectively closing the first air outlet or the second air outlet; wherein the double-opening air door is configured to open the first air outlet and close the second air outlet in a controlled mode when the temperature changing chamber sends out a refrigeration request, and open thesecond air outlet and close the first air outlet in a controlled mode when the temperature changing chamber does not send out a refrigeration request. The ice-making air return duct is provided with the first air outlet and the second air outlet, the return air of the ice-making chamber is utilized to provide cooling capacity for the temperature changing chamber, thus avoiding affecting the refrigeration effect of the refrigeration chamber.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an air-cooled refrigerator. Background technique [0002] An air-cooled refrigerator is a refrigeration device that circulates cold air in the refrigerator forcibly. As the demand for ice cubes increases gradually in businesses or households, ice-making chambers are usually arranged in existing air-cooled refrigerators. The return air in the ice-making chamber returns directly to the evaporator in the freezing chamber through the ice-making return air duct or returns to the freezing chamber, and then returns to the evaporator through the freezing return air outlet. [0003] At present, air-cooled refrigerators with variable temperature chambers need to arrange air supply ducts separately, and the air supply ducts are arranged in the back foam layer. In this way, the back foam layer needs to be thickened, resulting in difficult installation and operation, and the air supply L...

Problems solved by technology

[0003] At present, air-cooled refrigerators with variable temperature chambers need to arrange air supply ducts separately, and the air supply ducts are arranged in the back foam layer. In this way, the back foam layer needs to be thickened, resulting in difficult installation and operation, and the air supply Large resistance loss

Moreover, when the temperature-changing room needs to be refrigerated, the freezer is required to supply it with cold energy, but this will affect the cooling effect of the refrigerating room
