Title:
REFRIGERATING AND FREEZING DEVICE HAVING AIR-REGULATING FRESH-KEEPING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2018/103719
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 a sealed air-regulating fresh-keeping subspace (271), an air-regulating fresh-keeping system (80), a refrigeration system (70), a human-machine interactive system (120) and a controller (110) 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 refrigeration system (70) is configured to supply cold energy to the air-regulating fresh-keeping subspace (271). The human-machine interactive system (120) is configured to obtain an external operation and determine an air-regulating fresh-keeping indictor and a temperature indictor of the air-regulating fresh-keeping subspace (271) according to the external operation. The controller (110) is in signal connection with the human-machine interactive system (120), and is configured to control the air-regulating fresh-keeping system (80) and the refrigeration system (70) according to the air-regulating fresh-keeping indictor and the temperature indictor.
