refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises an air duct back plate, a fan and an air return cover plate, wherein the fan is mounted on the rear wall of an inner container and horizontally extends to a first air supply opening, and the fan is used for enabling cold air in an evaporator chamber to flow into a storage chamber through the first air supply opening; and the air return cover plate extends in the front-back direction, the front portion of the air return cover plate is provided with at least one air inlet, the rear portion of the air return cover plate is provided with at least one air outlet, and an air return channel enabling the at least one air inlet and the at least one air outlet to communicate is formed by the air return cover plate and the bottom wall of the inner container. The at least one air outlet communicates with the evaporator chamber, so that part of airflow in the storage chamber flows into the air return channel through the at least one air inlet, and then flows back to the evaporator chamber through the at least one air outlet. According to the refrigerator, vibration of the fan in the refrigerator can be reduced, and thus noise in the refrigerator is lowered; and the flowing area of airflow in the storage chamber of the refrigerator is enlarged, temperature distribution uniformity in the storage chamber is improved, comprehensive refrigeration is achieved, and thus the refrigerating effect is improved.

Description

technical field [0001] The invention relates to the field of refrigerated and frozen storage, in particular to a refrigerator. Background technique [0002] Refrigerators are indispensable household appliances in people's daily life. In recent years, air-cooled refrigerators have become more and more popular, and their features such as automatic defrosting, fast cooling speed, uniform distribution of air-conditioning, precise temperature control, and no odor transmission have been recognized by the majority of users. Existing air-cooled refrigerators are generally provided with an air duct backboard at the rear of the liner, the front of the air duct backboard is a storage compartment, and the rear of the air duct backboard is an evaporator room. In addition, a plurality of air supply ports and a plurality of return air ports are set on the back panel of the air duct, so that the cold air in the evaporator room can flow into the storage room through the plurality of air supp...

AI Technical Summary

Problems solved by technology

Because the air duct back panel is light and not stable enough, this method causes the fan to drive the air duct back panel to vibrate when it rotates, thereby generating a certain amount of noise, which is not conducive to the quietness of the refrigerator, especially at night, which has a certain impact on the user's rest. influences

In addition, on the basis of the existing air duct backplane and fan structure, it is generally necessary to install a glass tube defrosting heating wire under the evaporator. This method is costly, and the assembly is relatively complicated, and the defrosting effect is average.
