Title: REFRIGERATING AND FREEZING DEVICE AND DRAWER ASSEMBLY THEREOF
Abstract:
A drawer assembly (200), comprising: a cabinet (10) defining a controlled atmosphere fresh-keeping space (202) of which a front side is opened, a hollowed-out portion (13) being arranged on a top wall of the cabinet; a drawer (20), which can be inserted into the cabinet (10) in a push-pull manner from the front side of the cabinet (10); a housing (15), which is installed at the top wall of the cabinet (10) outside the cabinet (10) and covers the hollowed-out portion (13) in a sealing manner to define a containing cavity (11) together with the top wall of the cabinet (10); a controlled atmosphere membrane component (30), which is arranged within the containing cavity (11), has at least one controlled atmosphere membrane (31) and an oxygen-enriched gas collecting cavity, and is configured in such a way that more oxygen than nitrogen in the containing cavity (11) can penetrate through the controlled atmosphere membrane (31) to enter the oxygen-enriched gas collecting cavity; and a fan (40) arranged in the containing cavity (11), such that gas in the controlled atmosphere fresh-keeping space (202) flows into the fan (40) through one side of the hollowed-out portion (13) to be blown to the controlled atmosphere membrane component (30) by the fan (40), and then flows back from the other side of the hollowed-out portion (13).
