an air-cooled refrigerator

Abstract

The invention provides an air-cooled refrigerator. The air-cooled refrigerator includes a refrigerator, a freezer, a temperature-changing chamber, and a refrigerator door for opening and closing the refrigerator. An ice-making chamber is arranged on the refrigerator door. The air-cooled refrigerator also includes an ice-making return air duct, The ice-making return air duct includes: an air inlet connected to the ice-making chamber; a first air outlet connected to the temperature-changing chamber; a second air outlet connected to the freezing chamber; In the channel, it is used to selectively close the first air outlet or the second air outlet; wherein the double-opening damper is configured to controlly open the first air outlet and close the second air outlet when the temperature-changing room sends out a cooling request, and when the temperature-changing room does not When a cooling request is issued, the second air outlet is opened and the first air outlet is closed in a controlled manner. In this application, the first air outlet and the second air outlet are arranged in the ice-making return air duct, and the return air of the ice-making chamber is used to provide cooling capacity for the variable chamber, thereby avoiding affecting the cooling 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
