Document Type and Number:
WIPO Patent Application WO/2022/242196
Kind Code:
A1
Abstract:
A refrigerator (10), comprising: a refrigerator body (200) having a first storage compartment (210) and at least one second storage compartment (220) formed therein; an electrolytic oxygen removal device (100), a portion of which is in airflow communication with the first storage compartment (210), used for consuming oxygen in the first storage compartment (210) by means of an electrochemical reaction, the electrolytic oxygen removal device (100) being formed with an exhaust port (112) for discharging oxygen; and a gas guide tube (300), an air inlet end of which is communicated with the exhaust port (112) and an air outlet end is communicated with the second storage compartment (220), configured to guide oxygen flowing through the exhaust port (112) to the second storage compartment (220). Since the electrolytic oxygen removal device (100) can create a low-oxygen preservation atmosphere for the first storage compartment (210), the gas guide tube (300) can guide the oxygen discharged from the electrolytic oxygen removal device (100) to the second storage compartment (220), and the electrolytic oxygen removal device (100) is combined with the gas guide tube (300), such that the refrigerator (10) of the present invention is easy to create a low-oxygen preservation atmosphere and a high-oxygen preservation atmosphere, is simple in structure, does not require a pressurizing device, is beneficial to simplifying the operation process, and reducing the operation cost and the maintenance cost of the pressurizing device.
