Air channel assembly of refrigerator

Abstract

The invention provides an air channel assembly of a refrigerator. Top ends of a pair of air channel sealing plates are tightly connected to the left side and the right side of the bottom end of an airchannel cover plate to form an air channel rear cover; air channel foam is tightly clamped between an air channel surface hood and the air channel rear cover; vertical grooves in the left end and theright end are sealed by the air channel rear cover and are used as a left air feeding flow channel and a right air feeding flow channel; the overall air channel assembly is assembled on a refrigerating chamber inner container by taking the rear back part as a mounting surface; a cavity is formed among the middle part of the air channel foam, a vertical concave part between the left air feeding flow channel and the right air feeding flow channel and the refrigerating chamber inner container and is used as an air returning flow channel; a plurality of air outlets are respectively distributed atintervals from top to bottom on the left side and the right side of the air channel assembly corresponding to the left air feeding flow channel and the right air feeding flow channel; an air inlet inthe top end is communicated with a freezing air channel; the air returning flow channel is communicated with an evaporator chamber in the upper part through a refrigerating air returning inlet; an opening in the middle part of the bottom end is used as an air returning opening. Through the air channel assembly of the refrigerator, the problems of short circuit between air feeding and air returning of the refrigerating chamber and great temperature difference between the chambers of the refrigerator at present can be solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, more specifically to an air duct assembly of a refrigerator. Background technique [0002] At present, the evaporator chamber of the air-cooled refrigerator with the upper freezer and the lower storage in the wide compartment is located at the back of the freezer. After the fan of the freezer duct is running, the cold air is sent to each floor of the freezer through the refrigerated air duct for cooling. The existing refrigerated air duct is designed for positive air outlet, the air outlet is located in the air supply channel of the refrigerated air duct, and the return air outlet is located on the top of the refrigerated room, which is close to the uppermost air outlet and without any partition structure. The refrigerated air duct with this structure In actual application, it usually causes a serious short-circuit problem in the air circulation on the uppermost layer of the refri...

AI Technical Summary

Problems solved by technology

For this reason, the present invention proposes an air duct assembly for a refrigerator, through reasonable design of the air circulation path and each air outlet, in order to solve the current problem of short circuit of air intake and return air in the refrigerating chamber of the refrigerator and large temperature difference between the compartments
