FIG. 13 is a schematic diagram of the electric plate 400 of the storage device 200 for the refrigerator 10 shown in FIG. 3, and FIG. 14 is the electric plate 400 in the storage device 200 for the refrigerator 10 shown in FIG. A schematic diagram of the electrolysis section 322 directly above the electrolysis section 322. FIG. 15 is the case where the electric plate 400 in the storage device 200 for the refrigerator 10 shown in FIG. 3 is located at a certain position away from the electrolysis section 322 of the deoxygenation and moisture-permeable assembly 300 16 is a schematic diagram of the electric board 400 in the storage device 200 for the refrigerator 10 shown in FIG. 3 when the electric plate 400 is located at another position deviated from the electrolysis part 322 of the oxygen-removing and moisture-permeable assembly 300.

The electric plate 400 is arranged above the electrolysis part 322 and is configured to control translation to adjust the contact area between the electrolysis part 322 and the external water vapor of the storage container 210. A rack 410 is provided on the side of the electric plate 400 facing the electrolysis part 322. The rack 410 may be located in the middle of the electric plate 400 and extend from one end of the electric plate 400 to the other end of the electric plate 400 in the longitudinal direction to define The range of movement of the electric board 400. In this embodiment, the motorized plate 400 may be located directly above the electrolysis part 322 to shield the electrolysis part 322, so that the electrolysis part 322 is separated from the water vapor outside the storage container 210 and avoid water outside the storage container 210. The vapor contacts the electrolysis part 322, so that the electrolysis part 322 reduces the electrochemical reaction rate due to insufficient reactants, and even no electrochemical reaction occurs. That is, when the electromotive plate 400 is located directly above the electrolysis part 322, the oxygen removal assembly 320 The electrochemical reaction rate is the lowest. The electric plate 400 can also be translated along the extension direction of the rack 410 to a position deviated from directly above the electrolysis part 322 to remove the shielding of the electrolysis part 322 and change the contact area between the electrolysis part 322 and the water vapor outside the storage container 210 by moving , To adjust the electrochemical reaction rate of the electrolysis part 322. When the motorized board 400 moves to a position where the electrolysis part 322 is completely exposed, the electrolysis part 322 has the largest contact area with the water vapor outside the storage container 210, and has the most full contact with the water vapor outside the storage container 210. The reaction rate is the fastest.

The translational movement of the electric plate 400 is used to adjust the contact area between the electrolysis part 322 and the water vapor outside the storage container 210, and the electrochemical reaction rate of the oxygen removal assembly 320 can be adjusted without changing the electrolysis voltage of the oxygen removal assembly 320. Simplified control procedures.

In this embodiment, the driving device 500 is adjacent to the electric plate 400 to drive the electric plate 400 to perform a reciprocating translational movement.

The fan assembly 340 is disposed under the electric board 400 and adjacent to the driving device 500, and is configured to promote the formation of an air flow blowing toward the electrolysis part 322 to provide water vapor to the electrolysis part 322.

In this embodiment, the fan assembly 340 may include a fan frame for fixing the fan assembly 340 and a fan installed in the fan frame; the fan may be a miniature axial flow fan, the rotating shaft of which is perpendicular to the electrolysis part 322, and is used to The water vapor outside the storage container 210 is blown toward the electrolysis part 322. Since the reactant of the electrolysis unit 322 is water vapor, the electrolysis unit 322 needs to constantly replenish water so that the electrolysis reaction can continue. When the deoxygenation component 320 is turned on, the control circuit supplies power to the oxygen-consuming part 323 and the electrolysis part 322 respectively, and the fan assembly 340 is turned on. The fan assembly 340 blows air to the electrolysis part 322 while simultaneously blowing water vapor in the air to The electrolysis part 322 provides reactants to the electrolysis part 322. Since the internal temperature of the refrigerator 10 is generally low, the storage compartment 111 has a relatively humid atmosphere, and the air contains a large amount of water vapor. Therefore, the fan assembly 340 can prompt the air in the storage compartment 111 to provide sufficient reactants for the electrolysis part 322, and there is no need to separately provide a water source or a water delivery device for the deoxygenation assembly 320.

The fan assembly 340 and the deaeration assembly 320 are jointly arranged in the deaeration chamber 311, which shortens the distance between the fan assembly 340 and the deaeration assembly 320, improves the air supply efficiency of the fan assembly 340, and can quickly turn on the fan assembly 340.
