The communication assembly 300 is provided with a mounting frame 340 at an end of the communication channel 320 facing the external environment. The end of the communication channel 320 facing the external environment of the communication assembly 300 is the first end of the communication assembly 300.

The exhaust port 112 can be used to exhaust gases generated during the electrochemical reaction of the electrolytic oxygen removal device 100, such as oxygen generated by the anode plate 140.
Since the electrolytic oxygen removal device 100 has the exhaust port 112 for direct communication with the external environment, oxygen generated by the electrolytic oxygen removal device 100 can be directly discharged to the external environment through the exhaust port 112. By adopting the technical scheme of the embodiment, an exhaust pipeline does not need to be arranged on the refrigerator 10, and the electrolytic oxygen removal device 100 can smoothly exhaust generated oxygen while the structure of the refrigerator 10 is simplified. The communicating component 300 has a dual function of providing a positioning function for the installation process of the electrolytic oxygen removal device 100 and providing a flow channel for the airflow in the storage compartment 222 to flow to the electrolytic oxygen removal device 100.

Fig. 2 is a schematic diagram of a refrigerator 10 according to one embodiment of the present invention. Fig. 3 is a schematic exploded view of the cabinet 200 of the refrigerator 10 shown in fig. 2, with the electrolytic oxygen removal device 100 concealed.
The case 200 includes a case 210 and an inner container 220. The housing 210 has a first opening 211. The inner container 220 is disposed in the housing 210, and a storage compartment 222 is formed therein, and the inner container 220 is opened with a second opening 221 opposite to the first opening 211. The size of the first opening 211 may be equal to or larger than the size of the second opening 221.
Fig. 4 is a schematic view of a partial structure of the refrigerator 10 shown in fig. 2, with the inner container 220 hidden and showing the communication assembly 300. Fig. 5 is a schematic view of another part of the structure of the refrigerator 10 shown in fig. 2, with the cabinet 210 hidden and showing the communication assembly 300.
The first end of the communication assembly 300 communicates with the external environment through the first opening 211, and the second end of the communication assembly 300 communicates with the storage compartment 222 through the second opening 221, so that a communication passage 320 is formed between the first end and the second end of the communication assembly 300.

In this embodiment, the first opening 211 is located at the rear side of the cabinet 210. The second opening 221 is located at the rear side of the inner container 220. The communication assembly 300 extends rearwardly from the second opening 221 to the first opening 211. So configured, the electrolytic oxygen removal device 100 can also be located on the rear side of the refrigerator 10, which is advantageous for ensuring the aesthetic appearance of the refrigerator 10. In this case, directional terms such as "front" and "rear" are used with respect to the actual usage state of the refrigerator 10, and the bidirectional arrows in fig. 3 and 4 show the front and rear directions of the refrigerator 10.
The second end of the communication component 300 is embedded in the inner periphery of the second opening 221, or surrounds the outer periphery of the second opening 221, so that the second end of the communication component 300 is in sealed communication with the storage compartment 222 through the second opening 221, and thus, the gas in the storage compartment 222 does not leak in the process of flowing from the second opening 221 to the communication channel 320. The outer edge of the second opening 221 refers to an edge of the second opening 221 facing away from the inner space of the storage compartment 222. The inner periphery of the second opening 221 defines the second opening 221.
Fig. 6 is a schematic view of a partial structure of the communication assembly 300 of the refrigerator 10 shown in fig. 5, showing the installation frame 340 and the connection frame 360.
The mounting frame 340 is formed at a first end of the communicating member 300 and is embedded in an inner circumference of the first opening 211. The inner periphery of the first opening defines a first opening 211. The first end of the communicating member 300 is further formed with a connecting frame 360, and the connecting frame 360 is formed at least partially on the outer side periphery of the mounting frame 340 and abuts against the inner side edge of the first opening 211. That is, the communicating component 300 further includes a connecting frame 360 disposed around at least a portion of the outer side periphery of the mounting frame 340, and the connecting frame 360 abuts against the inner side edge of the first opening 211, so that the mounting frame 340 is fixed at the first opening 211, and the cold in the box 200 can be reduced or prevented from dissipating from the gap between the mounting frame 340 and the first opening 211, which is beneficial to improving the structural stability and the tightness of the box 200. For example, the connection frame 360 may be tightly attached to the inner edge of the first opening 211 by gluing, screwing, or any other fixing method. The inner edge of the first opening 211 refers to an edge of a side of the first opening 211 facing away from an external environment.
In some embodiments, the refrigerator 10 may further include a blower 500 disposed at the second opening 221 and configured to promote formation of a flow of air blown from the storage compartment 222 toward the electrolytic oxygen removal device 100 to provide oxygen to the electrolytic oxygen removal device 100.
Fig. 7 is a further schematic view of another portion of the refrigerator 10 shown in fig. 5, with the cabinet 210 hidden and the blower 500 shown. The fan 500 may be an axial flow fan 500, but is not limited thereto. This fan 500 can be fixed on a fretwork support through the spiro union, and this fretwork support can be fixed in second opening 221 department, for example can spiro union in the internal periphery of second opening 221. And the air supply area of the fan 500 can be just opposite to the hollow part of the hollow bracket, so that the air flow can smoothly pass through the hollow bracket.
By providing the blower 500 at the second opening 221 to supply oxygen to the electrolytic deoxygenator device 100, it is advantageous to increase the flow velocity of the gas stream, thereby achieving rapid deoxygenation.
Fig. 8 is a schematic exploded view of the electrolytic deoxygenator device 100 of the refrigerator 10 shown in fig. 2. Electrolytic oxygen removal device 100 may include a housing 110, a cathode plate 120, and an anode plate 140.
The housing 110 is disposed in the mounting frame 340, and an exhaust port 112 is formed thereon. For example, the outer frame 341 of the mounting frame 340 may define a square mounting space, and the outer shape of the housing 110 may be substantially rectangular parallelepiped and adapted to the outer shape of the outer frame 341 of the mounting frame 340. The interior of the housing 110 defines an interior space for housing the other components of the electrolytic oxygen removal device 100.
The mounting frame 340 has an outer frame 341 for being clamped with the housing 110, and a hollow area 342 located in the outer frame 341 and communicated with the communication channel 320. The casing 110 is provided with an oxygen inlet 114 facing the hollow area 342, and the cathode plate 120 is disposed at the oxygen inlet 114 and seals the oxygen inlet 114 and the hollow area 342 to prevent air in the external environment from entering the communicating channel 320, which is beneficial to improving the air tightness of the box body 200 of the refrigerator 10, thereby ensuring the fresh-keeping effect.
The mounting frame 340 further has a closed region 343 located inside the outer frame 341 and above the hollow region 342. There is a gap between the top of the housing 110 and the outer frame 341, and the exhaust port 112 is located on the side of the sealing area 343 facing the external environment. By providing the sealing region 343 in the outer frame 341, the airtightness of the case 200 can be ensured while a gap is formed between the top of the casing 110 and the outer frame 341, and it is convenient for oxygen to smoothly escape from the exhaust port 112 and for replenishing the electrolyte at the exhaust port 112.
The cathode plate 120 is disposed in the housing 110 and faces the communication channel 320 for consuming oxygen inside the storage compartment 222 through an electrochemical reaction. For example, oxygen in the air may undergo a reduction reaction at cathode plate 120, i.e.: o is2+2H2O+4e-→4OH-。
The anode plate 140 is disposed in the casing 110 and located on a side of the cathode plate 120 opposite to the communication channel 320, and is used for providing reactants to the cathode plate 120 through an electrochemical reaction and generating oxygen. For example, OH "produced by cathode plate 120 may undergo an oxidation reaction at anode plate 140 and produce oxygen, i.e.: 4OH- → O2+2H2O +4 e-. The exhaust port 112 is disposed on the casing 110, so that oxygen generated by the anode plate 140 can be exhausted in time to ensure the electrochemical reaction to proceed smoothly, thereby removing oxygen in the compartment. In this embodiment, the material of the anode plate 140 may be nickel, but is not limited thereto.
In some embodiments, the refrigerator may further include a power supply module, such as a battery.
