Abstract

The invention provides an air supply device, a refrigerator and a control method of the refrigerator. The air supply device comprises a shell body which is hollow to form an accommodating space, a draught fan arranged in the accommodating space, a first cover fixed to the shell body and located on the air outlet side of the draught fan, and a second cover arranged on the outer side of the first cover in a covered mode, wherein an air outlet cavity communicating with the accommodating space is formed in a first end surface part and a first peripheral wall part of the first cover, a first opening is formed in the first end surface part, and a second opening is formed in the first peripheral wall part; the inner surfaces of a second end surface part and a second peripheral wall part of the second cover are correspondingly in fit with the outer surfaces of the first end surface part and the first peripheral wall part, a first air outlet is formed in the second end surface part, a second air outlet is formed in the second peripheral wall part, and the second air outlet and the first air outlet are staggered along the circumferential position; and the second cover is operable to rotate to different positions relative to the first cover, so that the first opening corresponds to or is staggered with the first air outlet, and the second opening corresponds to or is staggered with the second air outlet, so as to adjust the air outlet state of the air supply device.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to an air supply device, a refrigerator and a control method for the refrigerator. Background technique [0002] In recent years, with the improvement of people's living standards and the enhancement of environmental awareness, the requirements for refrigerators have shifted from satisfying low-temperature refrigeration to keeping food fresh. Therefore, air-cooled refrigerators are gradually favored by people. For air-cooled refrigerators, the fresh-keeping performance of food depends to a large extent on the air circulation in the refrigeration compartment of the air-cooled refrigerator and the temperature difference between various parts in the box. The air circulation in the box is reasonable, and the smaller the temperature difference, the better the freshness preservation performance of the refrigerator. The key component that determines whether the a...
