Air duct system of a refrigerator and its compartment

Abstract

An air duct system for a refrigerator compartment includes an air duct device. The air duct device includes a first cover plate, a second cover plate, an air duct piece and a fan, the air duct piece is installed between the first cover plate and the second cover plate, and the first cover plate is close to On the opening surface of the compartment, the second cover plate is installed close to the rear wall of the inner cavity of the compartment, and the fan is obliquely installed on the second cover plate. There is a first cold air channel between the air channel member and the first cover plate, and a first warm air channel between the second cover plate, and the fan is connected to the first cold air channel connected. The air duct device is provided with an air return port, communicating with the first warm air duct; the first cover plate is provided with an air outlet, communicating with the first cold air duct. The present invention also provides a refrigerator, which includes a compartment. The above-mentioned air duct system is installed in the compartment, which solves the problems of low cooling efficiency, uneven air supply and large temperature difference in the compartment.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to the air duct system of refrigerator compartments. Background technique [0002] With the gradual improvement of people's living standards, people's demand for refrigerator capacity is also gradually increasing, so refrigerator manufacturers have manufactured large-capacity refrigerators. Since the lateral width of the large-capacity refrigerator compartment is wider than that of the small-capacity refrigerator compartment, it is difficult for the air duct system of the small-capacity refrigerator compartment to meet the cooling air supply demand of the large-capacity refrigerator compartment. [0003] The compartment of the large-capacity refrigerator has a relatively large cavity space, and the compartment of the refrigerator is usually provided with storage devices such as drawers, and the storage devices are generally stacked. The traditional air duct system is relative...

AI Technical Summary

Problems solved by technology

The traditional air duct system is relatively simple, which is suitable for the compartments of small-volume refrigerators. For the compartments of large-capacity refrigerators equipped with the above-mentioned storage device, it is easy to cause problems such as uneven air supply and slow circulation of cold air.

This will easily cause a large temperature difference in the inner cavity of the compartment, uneven temperature distribution, reduced refrigeration efficiency, and faster food spoilage
