Problems solved by technology

[0010] However, in the polymer electrolyte membrane method, it is necessary to supply the water electrolyzed at the anode, so it must be placed at a position where water in the refrigerator can be easily supplied, and there is a problem that the arrangement of the storage container is limited.

no. 1 Embodiment approach

[0035] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0036] Such as figure 1 as well as figure 2 As shown, the refrigerator 10 according to the present embodiment includes a housing 11 with an insulating material arranged between an outer box forming an outer outline and an inner box forming a storage space and opening toward the front, and the storage space is divided by an insulating partition wall 12 . It is divided into an upper refrigerating space 20 and a lower freezing space 40 .

[0037] The refrigerated space 20 is a space cooled to a refrigerated temperature (for example, 2 to 3° C.), and the interior is further divided up and down by a partition plate 21. In the upper space, a refrigerated room 22 with multiple layers of shelves is provided. Vegetable compartment 24 in which drawer-type storage container 25 is disposed is provided.

[0038] The opening of refrigerator compartment 22 is closed by refr...

Deformed example 1

[0080] In the above-mentioned first embodiment, the case where the water stored in the water storage unit 111 is supplied from the water supply unit 130 to the outside of the vaporization layer 122 on the anode catalyst layer 112 side of the oxygen reduction device 106 by capillary action has been described. But for example it is also possible as Figure 4 As shown, the defrosted water generated by the evaporator 141 stored in the water storage unit 142 is sent to the oxygen reducing device 106 by the pump 140A. Thereby, the water storage part 142 can be arrange|positioned at the position in a refrigerator where water supply is easy, without considering the position of the oxygen reduction device 106. FIG.

[0081] In this modified example, a heater 145 may be provided to heat the path 144 through which the pump 140A sends the defrosted water from the water storage unit 142 to the oxygen reducing device 106 , thereby preventing defrosting water flowing in the path 144 . Freez...

Deformed example 2

[0084] In the first embodiment described above, the case where the defrosted water generated in the refrigerating evaporator 52 is supplied to the oxygen reducing device 106 has been described, but the defrosted water generated in the refrigerating evaporator 54 and The ice-making water stored in the ice-making tank is supplied to the oxygen reducing device 106 . The other configurations and functions and effects are the same as those of the first embodiment, and detailed description thereof will be omitted.

Abstract

The present invention provides a refrigerator which reduces oxygen in a storage container by a polymer electrolyte film method and improves the convenience of use without limitation on the arrangement of the storage container. The refrigerator includes an oxygen reduction room (100) which is installed in a cabinet (11), an oxygen reducing device (106) which has a polymer electrolyte film (116) fitted into a pair of electrodes (118, 120) and is separated from the oxygen reduction room (100), and a duct (101, 103) which connects the oxygen reduction room (100) to the oxygen reducing device (106). The oxygen reducing device (106) reduces oxygen in the oxygen reduction room (100) by generating water from the oxygen of the oxygen reduction room (100) supplied through the duct (101,103) and hydrogen ions generated by the electrolysis of water.

Description

technical field [0001] Embodiments of the present invention relate to refrigerators. Background technique [0002] Oxidation due to oxygen present in the air exists as a factor of deterioration of stored goods such as food stored in a refrigerator. Therefore, there is known a refrigerator capable of maintaining the freshness of stored products by reducing oxygen in a space for storing foods to suppress oxidation of stored products. [0003] As methods for reducing oxygen, there are known a vacuum method that decompresses the inside of a storage container, an oxygen adsorption method that uses an oxygen adsorbent to absorb oxygen in a storage container, and a polymer electrolyte membrane that reduces oxygen in a storage container. Various methods such as the electrolyte membrane method.
