Title:
REFRIGERATING AND FREEZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/128717
Kind Code:
A1
Abstract:
A refrigerating and freezing device, the refrigerating and freezing device comprising: a casing (20) including an inner container (61), a housing (67) and a heat preservation layer, the inner container (61) being internally provided with a storage space (611), a storage container being disposed in the storage space (611), and the storage container being provided with a controlled atmosphere fresh-keeping space therein; and a controlled atmosphere membrane component (30) configured to allow more oxygen gas of air flows in a space around the controlled atmosphere membrane component (30) than nitrogen gas of air flows in the space around the controlled atmosphere membrane component (30) to pass through a controlled atmosphere membrane (31) to enter an oxygen gas enriched collecting cavity. The storage space consists of a top cover (21) and a bottom box (22); a concave cavity is disposed in a lower surface of the top cover (21), and the controlled atmosphere membrane component (30) is disposed in the concave cavity. A space for amounting the controlled atmosphere membrane component (30) is not needed to be configured separately, and an opening for communicating the controlled atmosphere membrane component (30) and the controlled atmosphere fresh-keeping space is not needed to be formed in a top surface of the storage container; therefore, the storage container of the refrigerating and freezing device has an integrated surface substantially without a slot, and the air tightness of the storage container is guaranteed.
