Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2021/223455
Kind Code:
A1
Abstract:
A refrigerator (100), comprising a refrigerator body (1), a drawer seat (2), a drawer body (3), at least one air-conditioning membrane assembly (7), and an air extractor (8). A low-temperature storage space (14) is formed in the refrigerator body (1), the drawer seat (2) is provided in the low-temperature storage space (14), and the end of the drawer seat (2) distant from a rear side wall (13) of the refrigerator body (1) is open and hollow; the drawer body (3) has a storage cavity (4) mounted in the drawer seat (2); a mounting cavity (5) and a backflow cavity (6) communicated with each other are defined between the drawer body (3) and the drawer seat (2); the mounting cavity (5) and the backflow cavity (6) are respectively provided on the different sides of the drawer body (3), and are respectively communicated with the storage cavity (4); the air-conditioning membrane assembly (7) is provided in the mounting cavity (5), and an oxygen transmission rate thereof is greater than a nitrogen transmission rate; and the air extractor (8) is provided in the low-temperature storage space (14) and configured to suction air in the air-conditioning membrane assembly (7), so that the air in the storage cavity (4) enters the mounting cavity (5), passes through the air-conditioning membrane assembly (7) in the mounting cavity (5) for deoxidization and filtration, and flows back to the storage cavity (4) through the backflow cavity (6), and the air in the drawer seat (2) is deoxidized and filtered by means of cyclic flowing, thereby greatly improving the air conditioning efficiency.
