REFRIGERATING AND FREEZING DEVICE HAVING AIR-REGULATING FRESH-KEEPING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2018/103731
Kind Code:
A1
Abstract:
A refrigerating and freezing device having an air-regulating fresh-keeping function comprises a box body (20) in which a storage space is defined, and comprises an air-regulating fresh-keeping subspace (271), an air-regulating fresh-keeping system (80) and a working condition detection system (70) that are formed in the storage space. The air-regulating fresh-keeping system (80) comprises an air-regulating membrane assembly (30) and an air extracting pump (40). The air extracting pump (40) is configured to make the gas in the air-regulating fresh-keeping subspace (271) permeate through the air-regulating membrane assembly (30), so that a gas atmosphere favorable for food preservation is formed in the air-regulating fresh-keeping subspace (271). The working condition detection system (70) is configured to detect the working states of the air-regulating membrane assembly (30) and the air extracting pump (40), and outputs prompt information when the working states are abnormal.
