Title:
REFRIGERATION AND FREEZING DEVICE AND OXYGEN REMOVAL CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/105427
Kind Code:
A1
Abstract:
A refrigeration and freezing device and an oxygen removal control method thereof, the refrigeration and freezing device having a storage container (100) inside thereof, an electrolytic oxygen removal assembly (200) being provided on a surface of the storage container (100), and the electrolytic oxygen removal assembly (200) comprising: an anode plate (220), a cathode plate (230), a proton exchange membrane (210) and a battery (211), two electrodes of the battery (211) being controllably connected to the anode plate (220) and the cathode plate (230), and the electrolytic oxygen removal assembly (200) being configured to consume oxygen inside the storage container (100) by means of an electrolytic reaction. when it is detected that the oxygen concentration of the storage space (100) is low, the voltage applied to the anode and cathode plates by the battery (211) is proportionately increased, so as to improve the reaction speed; when it is detected that the oxygen concentration in the storage space (100) is high, the voltage of the battery (211) is proportionately reduced, so as to reduce the power consumption of the battery (211), and ensure that the electrolytic oxygen removal assembly (200) consumes the oxygen in the storage space (100) at a stable speed, thereby improving the operating stability of the electrolytic oxygen removal assembly (200).
