Fig. 13 is a schematic view of the electric board 400 of the storage device 200 for the refrigerator 10 in fig. 3, fig. 14 is a schematic view of the electric board 400 of the storage device 200 for the refrigerator 10 in fig. 3 located directly above the electrolytic portion 322 of the oxygen-removing moisture-permeable assembly 300, fig. 15 is a schematic view of the electric board 400 of the storage device 200 for the refrigerator 10 in fig. 3 located at a position deviated from a position directly above the electrolytic portion 322 of the oxygen-removing moisture-permeable assembly 300, and fig. 16 is a schematic view of the electric board 400 of the storage device 200 for the refrigerator 10 in fig. 3 located at another position deviated from a position directly above the electrolytic portion 322 of the oxygen-removing moisture-permeable assembly 300.

And the electric plate 400 is arranged above the electrolysis part 322 and is configured to be controlled to translate so as to adjust the contact area of the electrolysis part 322 and the water vapor outside the storage container 210. The side of the electric board 400 facing the electrolysis part 322 is provided with a rack 410, and the rack 410 may be located at a middle portion of the electric board 400 and extend from one end of the electric board 400 to the other end of the electric board 400 in a longitudinal direction to define a movement range of the electric board 400. In this embodiment, the electric plate 400 may be located directly above the electrolysis portion 322, and serves to shield the electrolysis portion 322, so that the electrolysis portion 322 is separated from the water vapor outside the storage container 210, and the water vapor outside the storage container 210 is prevented from contacting the electrolysis portion 322, so that the electrochemical reaction rate of the electrolysis portion 322 is reduced due to insufficient reactants, and even no electrochemical reaction occurs, that is, when the electric plate 400 is located directly above the electrolysis portion 322, the electrochemical reaction rate of the oxygen removing assembly 320 is the lowest. The electric board 400 can also translate along the extending direction of the rack 410 to a position deviated from the position right above the electrolysis part 322 to release the shielding of the electrolysis part 322, and change the contact area of the electrolysis part 322 and the water vapor outside the storage container 210 through movement to adjust the electrochemical reaction rate of the electrolysis part 322. When the electric plate 400 moves to a position where the position directly above the electrolysis portion 322 is completely exposed, the area of the electrolysis portion 322 in contact with the water vapor outside the storage container 210 is the largest, the area of the electrolysis portion 322 in contact with the water vapor outside the storage container 210 is the most sufficient, and the rate of the electrochemical reaction is the fastest.

The contact area of the electrolysis part 322 and the water vapor outside the storage container 210 is regulated and controlled by utilizing the translational motion of the electric plate 400, the electrochemical reaction rate of the oxygen removing assembly 320 can be regulated under the condition of not changing the electrolysis voltage of the oxygen removing assembly 320, and the control procedure is simplified.

Since the reactant of the electrolysis unit 322 is water vapor, the electrolysis unit 322 needs to be constantly replenished with water so that the electrolysis reaction can be continuously performed. When the oxygen removing assembly 320 is started to work, the control circuit respectively supplies power to the oxygen consumption part 323 and the electrolysis part 322, meanwhile, the fan assembly 340 is started, and the fan assembly 340 blows air to the electrolysis part 322 and simultaneously blows water vapor in the air to the electrolysis part 322 so as to provide reactants to the electrolysis part 322. Since the interior temperature of the refrigerator 10 is generally low, the storage compartment 111 has a relatively humid gas atmosphere, which contains a large amount of water vapor in the air. Accordingly, the fan assembly 340 can cause the air in the storage compartment 111 to provide sufficient reactant to the electrolysis portion 322 without the need for a separate water source or delivery device for the oxygen scavenging assembly 320.

Set up fan subassembly 340 and deoxidization subassembly 320 jointly in deoxidization chamber 311, shortened the distance between fan subassembly 340 and the deoxidization subassembly 320, improved fan subassembly 340's air supply efficiency, fan subassembly 340 can provide the required vapor of electrolytic reaction for deoxidization subassembly 320 fast after opening, is favorable to improving the electrolytic efficiency of deoxidization subassembly 320, realizes falling oxygen fast.
