REFRIGERATION AND FREEZING APPARATUS AND OXYGEN REMOVAL CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/105428
Kind Code:
A1
Abstract:
A refrigeration and freezing apparatus and an oxygen removal control method therefor. A storage container (100) is provided within the refrigeration and freezing apparatus. An electrolytic oxygen removal component (200) is provided on the surface of the storage container (100). The electrolytic oxygen removal component (200) comprises an anode plate (220), a cathode plate (230), a proton exchange membrane (210), a battery (2233), and a fan (250) used for blowing water vapor towards the anode plate (220). Either electrode of the battery (2233) is controllably connected to the anode plate (220) and to the cathode plate (230). The electrolytic oxygen removal component (200) is configured to consume the oxygen in the storage container by means of an electrolysis reaction. When a door body (20) of the refrigeration and freezing apparatus is detected as being opened by a user, the fan (250) of the electrolytic oxygen removal component (200) is automatically turned off or the fan (250) is kept in a turned-off state, thus preventing the user from being affected by the noise generated by the fan when the user is using the refrigeration and freezing apparatus, and implementing silenced use of the refrigeration and freezing apparatus.
