Air Duct Module and Refrigerator

Abstract

The invention relates to an air channel module and a refrigerator. The air channel module comprises air channel walls, an air channel chamber and a heat insulation wall, wherein the air channel chamber is formed by the air channel walls in a surrounding mode; the heat insulation wall is made of a heat insulation material and is used for partitioning the air channel chamber into at least two independent sub-air channel chambers; each sub-air channel chamber is correspondingly provided with an air inlet and an air outlet. Due to the fact that the air channel module is provided with at least two sub-air channel chambers and the heat insulation materials are arranged between the adjacent sub-air channel chambers, the sub-air channel chambers are integrated into a module, mutual heat exchange and mutual mass exchange are avoided, a refrigerator assembly is simplified to facilitate assembly, repeated operation caused by repeated assembly is reduced, and the probability of assembly problems is reduced. Due to arrangement of the air channel module, the refrigerator is easy to assemble, the using performance of the refrigerator is improved, the labor cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an air duct module and a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a product that keeps food or other items at a constant low temperature. Existing multi-temperature zone refrigerators generally include a refrigerating room, a freezing room, a variable temperature room, and air ducts respectively arranged outside the refrigerating room, freezing room, and variable temperature room. Refrigeration, the cooling capacity is sent to the refrigerator, freezer, and variable room through the air supply duct, and the heat in the refrigerator, freezer, and variable room enters the return air duct, thereby realizing the refrigeration cycle. The air duct includes a supply air duct and a return air duct. Since the temperature of the return air in each room is different, it is impossible to use the same return air duct to return air, otherwi...

AI Technical Summary

Problems solved by technology

The air ducts of the refrigerating room, the variable room and the freezing room of the existing refrigerator are all set separately, so the number of air ducts is large, the assembly process is many, time-consuming, and the cost is high. The air inlets in the compartments need to be aligned separately, so the assembly is cumbersome and time-consuming, and due to the need for multiple alignments, it often happens that the alignment between the air duct and the air inlets in the compartments is not accurate, resulting in subsequent production and user use. The leakage problem of
