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
[0003] 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 complicated to assemble, and the defrosting effect is average.

Abstract

The invention provides a refrigerator. The refrigerator comprises a liner, and further comprises an air duct back plate and a draught fan, wherein the air duct back plate is arranged in the liner, the air duct back plate and the liner define a storage chamber located in front of the air duct back plate and an evaporator chamber located behind the air duct back plate, and a first air supply opening used for enabling cold air in the evaporator chamber to flow into the storage chamber is formed in the air duct back plate; and the draught fan is arranged on the rear wall of the liner and horizontally extends to the first air supply opening, and the draught fan is configured to promote the cold air in the evaporator chamber to flow into the storage chamber through the first air supply opening. According to the refrigerator, the vibration of the draught fan in the refrigerator can be effectively reduced, so that the noise of the refrigerator is reduced; and in addition, the cost of the refrigerator can be reduced, and the refrigerator is convenient to install.

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. The freezing air duct of the existing air-cooled refrigerator is generally composed of front and rear air duct cover plates, air ducts formed by foam, and fans, and the fans are installed on the air duct cover plates. 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, resulting in a certain amount of noise, which is not conducive to the quietness of the refrigera...
