Refrigerator

Abstract

The invention discloses a refrigerator, which comprises a refrigerator body, a door body of a freezing chamber, the door body of a refrigerating chamber, an ice maker and a refrigeration system, wherein the freezing chamber and the refrigerating chamber are formed in the refrigerator body; the refrigerating chamber is positioned above the freezing chamber; an ice-making chamber is arranged on an internal wall of the door body of the refrigerating chamber; an ice-taking groove which is connected with the ice-making chamber is arranged on an external surface of the door body of the refrigerating chamber; the ice maker is arranged in the ice-making chamber; the refrigeration system comprises a compressor, a condenser, a first evaporator, a second evaporator, a third evaporator and an electric switching valve; the compressor and the condenser are arranged in a compressor cabin which is positioned on the lower part of the rear side of the refrigerator body; the first evaporator is arranged in the freezing chamber and refrigerates the freezing chamber; the second evaporator is arranged in the refrigerating chamber and refrigerates the refrigerating chamber; the third evaporator is arranged in the ice-making chamber and refrigerates the ice-making chamber; the electric switching valve is connected with the first evaporator, the second evaporator and the third evaporator; and the first evaporator, the second evaporator and the third evaporator adopt a bypass control mode. The refrigerator provided by the embodiment of the invention has the advantages of good moisturizing effect, convenience for use, high refrigerating efficiency and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator. Background technique [0002] Existing refrigerators with automatic ice-making function are all single-system refrigerators, that is, the refrigeration system has only one evaporator, and the evaporator is located in the freezer compartment. The cold air is conveyed from the freezer to the refrigerator or ice-making room through the fan and the air duct. The air duct has a long stroke and the air flow resistance is relatively large, so the energy loss is relatively large. [0003] In addition, due to the structural characteristics of the single refrigeration system, the cold air circulates between the freezer, ice-making room, and refrigerating room, and the moisture in the refrigerating room will be lost to the freezing room, ice-making room, etc. Humidity is difficult to maintain, so the air-drying phenomenon of this type of refrigerator on the market is ...

Problems solved by technology

[0002] Existing refrigerators with automatic ice-making function are all single-system refrigerators, that is, the refrigeration system has only one evaporator, and the evaporator is located in the freezer compartment. The cold air is conveyed from the freezer to the refrigerator or ice-making room through the fan and the air duct. The air duct has a long stroke and the air flow resistance is relatively large, so the energy loss is relatively large.

[0003] In addition, due to the structural characteristics of the single refrigeration system, the cold air circulates between the freezer, ice-making room, and refrigerating room, and the moisture in the refrigerating room will be lost to the freezing room, ice-making room, etc. Humidity is difficult to maintain, so the air-drying phenomenon of this type of refrigerator on the market is more prominent at present, and foods with high water content such as vegetables and fruits have a shorter storage time

[0004] In addition, for the refrigerator that the automatic ice maker is arranged in the freezer and cannot take ice from the outside of the casing, it is necessary to open the door of the freezer and then take the ice when ice is needed, and because the existing refrigerator usually The freezer is located at the lower part of the refrigerator, and the user needs to bend over when taking ice, causing a lot of inconvenience, which is not conducive to the preservation of cold air in the freezer, and is prone to unnecessary energy loss
