And an electrolytic part 310 facing away from the inside of the storage container 200 and exposed to the outside of the storage container 200. A proton exchange membrane 330 for transporting hydrogen ions may be disposed between the oxygen consumption part 320 and the electrolysis part 310.

That is, the oxygen removing assembly 300 performs an electrochemical reaction using water vapor outside the container 200 and oxygen inside the container 200 as reactants to reduce the oxygen content inside the container 200. The electrochemical reaction includes two half reactions respectively occurring in the electrolysis portion 310 and the oxygen consumption portion 320, the electrolysis portion 310 electrolyzes water vapor outside the storage container 200 under the action of an electrolysis voltage to generate hydrogen ions and oxygen, the proton exchange membrane 330 is configured to transport the hydrogen ions from one side of the electrolysis portion 310 to one side of the oxygen consumption portion 320, and the oxygen consumption portion 320 promotes the hydrogen ions generated by the electrolysis portion 310 to electrochemically react with the oxygen inside the storage container 200 to generate water to consume the oxygen inside the storage container 200 under the action of the electrolysis voltage, so that a low-oxygen fresh-keeping environment is formed inside the storage container 200.

And two elastic plates 350 arranged outside the electrolysis part 310, wherein each elastic plate 350 is a rectangular thin plate, the middle part of each elastic plate is hollowed out, and the position and the shape of the hollowed-out part are matched with the position and the shape of the notch 341 of the mother plate 340 so as to allow gas to pass through. The elastic plate 350 is provided at an edge portion thereof with motherboard screw holes 351, and the positions and the number of the motherboard screw holes 351 are matched with those of the inscribed screw holes 342 of the motherboard 340 to fix the multi-layered structure of the oxygen removing assembly 300 on the motherboard 340 by screwing.

The rate of the electrochemical reaction is related to the concentration of the reactants, and an appropriate concentration of the reactants is beneficial to promote a high efficiency of the electrochemical reaction. If the oxygen scavenging assembly 300 is operated with insufficient water vapor or oxygen in the vicinity, meaning that the electrochemical reaction is occurring at a lower concentration of reactants, the rate of the electrochemical reaction will be correspondingly lower or no electrochemical reaction will occur at all, and the inability to supplement water vapor or oxygen to the oxygen scavenging assembly 300 will result in a very small benefit to the oxygen scavenging assembly 300 while consuming electrical energy. In addition, the life of the oxygen scavenging assembly 300 is related to the run time, which is the longer the life is, and thus, the electrochemical reaction rate of the oxygen scavenging assembly 300 needs to be increased by replenishing the oxygen scavenging assembly 300 with reactants.

The fan frame 152 can be fixed on the bottom surface of the fan cavity 112 by screwing, the air supply area of the electrolysis fan 151 is opposite to the electrolysis part 310, and the air suction area of the electrolysis fan 151 is opposite to the circular opening 105 in the middle of the fan frame 152. The fan frame 152 can fixedly support the electrolysis fan 151, prevent the electrolysis fan 151 from shaking during operation, and simultaneously enable a certain distance to be formed between the electrolysis fan 151 and the fan cavity 112, so as to facilitate gas circulation.

The bottom cover 221 further defines a water removal cavity 720 disposed adjacent to the oxygen removal opening 710, the water removal cavity 720 may be recessed toward the exterior of the storage container 200, and the bottom of the water removal cavity 720 is composed of a permeable region 721 and a non-permeable region 722. The air-permeable area 721 and the non-air-permeable area 722 may have a rectangular shape. The non-air-permeable regions 722 are located in the middle, the two air-permeable regions 721 are located on two sides of the non-air-permeable regions 722, and the arrangement directions of the air-permeable regions 721 and the non-air-permeable regions 722 may be sequentially arranged along the direction perpendicular to the depth direction of the refrigerator 10. The air permeable region 721 is a through hole arranged in an array, and the non-air permeable region 722 is not provided with through holes. The water removal cavity 720 is used for accommodating the moisture permeable component 400. The water removing chamber 720 is provided at a middle position of the bottom cover 221.

The moisture permeable assembly 400 is disposed in the water removal cavity 720 and configured to allow water vapor in the storage container 200 to permeate and drain. In this embodiment, the moisture permeable component 400 can be disposed on the air permeable region 721 at the bottom of the dewatering cavity 720 to seal the air permeable region 721, so that the water vapor in the storage container 200 can be discharged to the outside of the storage container 200 through the moisture permeable component 400 and the air permeable region 721. There may also be two moisture permeable assemblies 400 for simultaneous placement on both air permeable regions 721. That is, two moisture permeable components 400 are respectively located at both sides of the non-air permeable region 722.
