A kind of air supply device and refrigerator

Abstract

The invention discloses an air supply device and a refrigerator, and relates to the technical field of refrigeration equipment. According to the air supply device and the refrigerator, the control ofa plurality of air doors in a narrow air duct can be realized, and the cost is reduced. The air supply device comprises an air duct shell, an air cavity is formed in the air duct shell, the air duct shell comprises an air duct bottom plate and an air duct side wall, air outlets are formed in the air duct side wall, air doors used for opening and closing the air outlets are arranged at the positions where the air outlets are formed, rotating shafts and guide shafts are arranged on the air doors, the rotating shafts and the guide shafts are all perpendicular to the air duct bottom plate, the airdoors are hinged to the air duct shell through the rotating shafts, arc grooves are formed in the air duct bottom plate, circle centers of the arc grooves are located on rotating axes of the rotatingshafts, a rotatable guide disc is arranged on one side, away from the air cavity, of the air duct bottom plate, guide grooves are formed in the guide disc, one ends of the guide shafts penetrate through the arc grooves and extend into the guide grooves, when the guide disc rotates, the guide grooves can drive the guide shafts to rotate around the rotating shafts, so as to enable the air doors toswing between an open position and a closed position. The air supply device is used for supplying air for an air-cooled refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air supply device and a refrigerator. Background technique [0002] The interior of the refrigerator is used to store various foods, and the storage conditions (such as temperature) required by different foods are different. Therefore, there are often multiple storage rooms inside the refrigerator, and the temperatures of each storage room are different. The internal refrigeration system of the refrigerator is required to realize multiple storage compartments under different temperature conditions. At the same time, the refrigeration methods of the existing refrigerators include direct cooling and air cooling. The air cooling method can speed up the air flow in the refrigerator, and the cooling effect is good, and the temperature distribution in each storage room is even, and it can realize frost-free, which has a large Advantage. [0003] The prior art provi...

Problems solved by technology

[0004] However, refer to figure 1 , due to the limitation of the internal space of the refrigerator, the space in the air duct 02 is often relatively narrow, and in order to realize the opening or closing of different air ducts 02, multiple dampers may be set at different positions. The output shaft is directly connected to the air door to drive the air door to open or close, so it is necessary to install multiple motors. On the one hand, the layout of the narrow air duct 02 is not easy, and on the other hand, the cost is increased.
