Refrigerator

Abstract

The invention relates to the technical field of refrigeration equipment, and discloses a refrigerator. The refrigerator comprises a refrigerator body, an air duct assembly, an evaporator and a fan. A refrigerating chamber, a function chamber and a freezing chamber are defined in the refrigerator body, and a variable-temperature drawer is arranged in the refrigerating chamber; the air duct assembly is arranged in the refrigerator body and forms a freezing cavity channel, a refrigerating cavity channel, a first air return cavity channel and a second air return cavity channel; the freezing chamber is communicated with the freezing cavity channel and the first air return cavity channel; the variable-temperature drawer is communicated with the refrigerating cavity channel and the refrigerating chamber; the refrigerating chamber is communicated with the refrigerating cavity channel, the function chamber and the second air return cavity channel, one part of return air of the refrigerating chamber enters the function chamber, and the other part of return air enters the second air return cavity channel; the function chamber further communicates with the second air return cavity channel; the freezing cavity channel is communicated with the refrigerating cavity channel through an air door assembly; and the fan drives part of cold air to enter the freezing chamber, and the other part of cold air passes through the air door assembly. According to the refrigerator, only part of return air of the refrigerating chamber is used for refrigerating circulation in the function chamber, so that the problems of large temperature fluctuation and inaccurate temperature control of the function chamber are solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background technique [0002] For the user, the more compartment temperature ranges of the refrigerator are divided, the more convenient it is to use, and the user can store different types of food. However, for refrigerators with the same external size, the more compartments are divided into temperature zones, the higher the cost, the smaller the volume available to users, and it is difficult to accurately control the temperature of each zone. [0003] At present, some air-cooled three-door products on the market generally have the following layout: the upper part is a refrigerator, the middle is a functional room (such as a variable temperature room), and the lower part is a freezer. Most of these products are single-cycle refrigeration systems, and each room is controlled by air circulation. [0004] The products of the above mode have fewer f...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a refrigerator to solve the technical problems that the refrigerators in the prior art have fewer functional compartments, and the temperature fluctuations of the functional compartments are large, the temperature control is not accurate, and it is difficult to meet the needs of customers.
