There is no need to use installation tools to perform installation operations.

Since the oxygen treatment device 300 can directly contact the storage space through the ventilation port 610 without the need for air flow pipelines for gas exchange, the gas processed by the oxygen treatment device 300 can be directly discharged to the storage space. Based on the solution of the present invention, it is beneficial to shorten the air flow path between the oxygen treatment device 300 and the storage space and improve the air conditioning efficiency.

Therefore, when the oxygen treatment device 300 slides to the ventilation port 610, the housing 320 can be in contact with the ventilation port 610. The outer peripheries of 610 are in contact with each other to cover the ventilation opening 610, so that the storage space is in a sealed state to avoid air leakage.

In some optional embodiments, the wall of the storage container 600 is formed with a dimple 620 that is inwardly recessed toward the storage space to accommodate the housing 320 . The ventilation port 610 is located on the inner end wall of the cavity 620 . And the slideway 622 is located on the inner wall of the dimple 620 . When the outer protruding claw 328 extends into the sliding groove 622a, the housing 320 abuts against the inner end wall of the recess 620. The inner end wall of the dimple 620 is opposite to the opening of the dimple 620 .

When the oxygen treatment device 300 slides to the outside of the ventilation port 610, the ventilation port 610 can be covered and the ventilation port can be sealed tightly. 610.

By arranging a dimple 620 structure on the storage container 600 and allowing the oxygen treatment device 300 to slide along the slideway 622 defined by the inner wall of the dimple 620, under the protection of the dimple 620, the sliding process of the oxygen treatment device 300 It will not be disturbed by the external environment. Since the oxygen treatment device 300 is always located inside the recess 620 , when it slides to the ventilation port 610 , it will hardly come into contact with external objects, which is beneficial to improving the relationship between the oxygen treatment device 300 and the storage container 600 The stability of the assembly structure.

In some optional embodiments, an annular groove 624 that surrounds the ventilation port 610 and is recessed inward is formed on the inner end wall of the dimple 620 . The refrigeration and freezing device 10 may further include an annular sealing ring 650, which is disposed in the annular groove 624 and extruded against the oxygen treatment device 300 slid to the ventilation port 610 to achieve sealing. The sealing ring 650 may be a rubber sealing ring 650 .

By arranging an annular sealing ring 650 on the circumferential outside of the ventilation port 610, and pressing the annular sealing ring 650 and the oxygen treatment device 300 slid to the ventilation port 610, the oxygen treatment device 300 and the ventilation port 610 can be connected to each other. The outer periphery of 610 is tightly joined to prevent air leakage.

In some optional examples, the inner side wall of the dimple 620 is perpendicular to the inner end wall of the dimple 620 . There are two slideways 622 and they are located on two opposite inner walls of the cavity 620 . There are two protruding claws 328 , and they are respectively disposed on two opposite outer walls of the housing 320 .

For example, the dimple 620 may be formed on the back wall of the storage container 600 . The back wall of the storage container 600 may include a vertical plate section extending in the vertical direction and two horizontal plate sections perpendicular to the vertical plate section and extending outward in the horizontal direction and spaced apart from each other in the vertical direction. A dimple 620 is defined between the two horizontal plate sections. The vertical plate segments form the inner end face of the dimple 620 . The inner side of the dimple 620 refers to the opposite plate surface of the two horizontal plate sections. Each horizontal plate section may extend from one transverse end of the back wall of the storage container 600 to the other transverse end in the horizontal direction.

The two horizontal plate sections may have first and second convex ribs arranged parallel and spaced apart on the opposite plate surfaces respectively, and the first convex ribs and the second convex ribs are arranged parallel and spaced apart along the width direction of the horizontal plate sections. A sliding groove 622a into which the outer protruding claw 328 is inserted is defined between the first protruding rib and the second protruding rib.

In some optional embodiments, the refrigeration and freezing device 10 may further include a first positioning module 660 and a second positioning module 670 , which are spaced apart from each other along the sliding direction of the oxygen treatment device 300 on both sides of the ventilation port 610 , and clamp both ends of the housing 320 to position the oxygen treatment device 300 at the ventilation port 610 .

The first positioning module 660 and the second positioning module 670 are used to position the oxygen treatment device 300 in the At the air port 610, the displacement of the oxygen treatment device 300 relative to the ventilation port 610 can be reduced or avoided, thereby ensuring the sealing effect of the storage space and the oxygen regulation effect of the oxygen treatment device 300 for the storage space.

In one example, the end surface where the positioning pin abuts against the oxygen treatment device 300 may be a flat surface. The flat-mounted end surface is in contact with the oxygen treatment device 300, which can increase the contact area between the two and improve the stability of the positioning structure. The end surface of the positioning pin facing away from the oxygen treatment device 300 may be an arc-shaped curved surface, and for example, the cross-section of the arc-shaped curved surface may be in the shape of a semicircle. By providing an arc-shaped curved surface on the positioning pin, the frictional resistance that the positioning pin encounters when inserted into the through hole 626 can be reduced, thereby reducing the difficulty of assembly.

Figure 5 is a schematic structural diagram of an oxygen treatment device 300 according to an embodiment of the present invention. FIG. 6 is a schematic exploded view of the oxygen treatment device 300 shown in FIG. 5 . In some optional embodiments, the housing 320 has a lateral opening 321 opposite to the ventilation port 610 . For example, the housing 320 may be in the shape of a flat rectangular parallelepiped. The lateral opening 321 can be provided on any surface of the housing 320, such as the top surface, bottom surface or side surface. In one example, the lateral opening 321 may be provided on a surface of the housing 320 with the largest area.

The oxygen treatment device 300 also includes a cathode plate 330 and an anode plate 340. The cathode plate 330 is disposed at the lateral opening 321 to jointly define an electrochemical reaction chamber for containing electrolyte with the casing 320, and for consuming oxygen in the storage space through electrochemical reaction. The electrochemical reaction chamber is a place where the cathode plate 330 and the anode plate 340 perform electrochemical reactions. It can contain an alkaline electrolyte, such as 1 mol/L NaOH, and its concentration can be adjusted according to actual needs. Oxygen in the air can undergo a reduction reaction at the cathode plate 330, namely: O ₂ +2H ₂ O+4e ^- → 4OH ^- .

The anode plate 340 and the cathode plate 330 are spaced apart from each other and are arranged in the electrochemical reaction chamber, and are used to provide reactants to the cathode plate 330 and generate oxygen through electrochemical reactions. The OH ^- generated by the cathode plate 330 can undergo an oxidation reaction at the anode plate 340 and generate oxygen, that is: 4OH ^- →O ₂ +2H ₂ O+4e ^- .

The above examples of the electrochemical reaction of the cathode plate 330 and the anode plate 340 are only illustrative.

By opening a lateral opening 321 in the casing 320 opposite to the ventilation port 610, and connecting the cathode plate 330 Disposed at the lateral opening 321 of the casing 320, the cathode plate 330 can also communicate with the airflow of the storage space while closing the lateral opening 321, thereby consuming oxygen in the storage space through electrochemical reaction, thereby creating a low-temperature atmosphere in the storage space. Oxygen preservation atmosphere.

In some optional embodiments, the housing 320 is provided with a fluid replenishing port 322 connected to the electrochemical reaction chamber. The refrigeration and freezing device 10 further includes a liquid storage module 500, which has a box body 510. The interior of the box body 510 defines a liquid storage space for storing liquid. The liquid storage space is connected to the liquid replenishing port 322 to replenish electrolyte to the oxygen treatment device 300 . The liquid contained in the storage space may be water or electrolyte, and its concentration may be lower than the electrolyte contained in the electrochemical reaction chamber.

In some examples, the box body 510 is disposed within the foam layer or within the storage compartment 122 . The box body 510 is provided with a liquid outlet 511 connected to the liquid storage space to allow the liquid contained in the liquid storage space to flow out.

Refill the reaction chamber. The liquid outlet 511 is higher than the liquid replenishing port 322. In this way, the liquid in the liquid storage space can automatically flow into the electrochemical reaction chamber under the action of gravity without the need for a power device.

Of course, in other examples, the liquid outlet 511 can also be transformed to be lower than the liquid replenishment port 322 or be level with the liquid replenishment port 322 . At this time, a pump can be installed on the liquid replenishing pipeline 420 to drive the liquid in the liquid storage space to flow into the electrochemical reaction chamber under the action of the pump; or the siphon principle can be used to cause the liquid in the liquid storage space to flow into the electrochemical reaction chamber. .

In some further examples, a one-way valve may be provided on the fluid replacement pipeline 420 to allow one-way passage of liquid from the liquid outlet 511 to ensure one-way flow of liquid flowing through the fluid replacement pipeline 420 .

In other examples, the liquid storage module 500 can be integrally formed with the oxygen treatment device 300 , or fixedly connected to the oxygen treatment device 300 , for example, through a plug-in structure, which allows the liquid storage module 500 to be connected to the oxygen treatment device 300 Implement modularization and omit the pipeline structure between the two.

In some examples, the box 510 is disposed within the foam layer. The fluid replenishment pipeline 420 can be embedded in the foam layer. The first end of the fluid replenishment pipeline 420 is connected to the fluid replenishment port 322 of the oxygen treatment device 300, and the second end of the fluid replenishment pipeline 420 is connected to the liquid outlet 511 of the box 510 to guide the liquid flowing out of the liquid storage space from the liquid outlet 511. Lead to the liquid replenishment port 322 to replenish liquid to the electrochemical reaction chamber.

By disposing the box body 510 of the liquid storage module 500 in the foam layer, and making the liquid storage space of the box body 510 communicate with the oxygen treatment device 300, the liquid stored in the box body 510 can be used to replenish the oxygen treatment device 300. Electrolyte, since the box 510 does not occupy the storage space, the refrigeration and freezing device 10 can use the liquid storage module 500 to replenish the electrolyte to the oxygen treatment device 300 without affecting the volume ratio, so that the oxygen treatment device 300 can be sustainable Adaptively adjust the oxygen content of the storage space.

The box body 510 of the liquid storage module 500 can be disposed at any part of the foam layer, for example, it can be disposed on the side of the inner bladder 120 , or can be disposed on the top, bottom and back of the inner bladder 120 . For a French-style refrigerator or a T-type refrigerator, in one example, the box body 510 of the liquid storage module 500 may be disposed in the gap between the upper inner pot 120 and the lower inner pot 120 .

In some optional embodiments, the box body 100 also has a box shell 170 , and a foam layer is formed between the box shell 170 and the inner bladder 120 . The box shell 170 is covered on the outside of the foam layer to sandwich the foam layer with the inner bladder 120 .

The inner bladder 120 is provided with an opening-shaped interactive window 124 . Figure 7 is a schematic structural diagram of an inner bladder according to an embodiment of the present invention. The foam layer has a mounting groove communicating with the interaction window 124 for assembling the liquid storage module 500 . After the foam layer is formed, the liquid storage module 500 can be assembled into the installation groove, thereby being disposed in the foam layer. The installation groove can be reserved during the foam layer forming process. The installation groove is recessed in a direction away from the interaction window 124 along the thickness direction of the foam layer, and forms a gap with the box shell 170 . In other words, the mounting groove does not penetrate the foam layer, so that the liquid storage module 500 assembled into the mounting groove will not be tightly attached to the tank shell 170 . That is, a certain thickness of heat insulation material is formed between the box shell 170 and the oxygen treatment device 300 .

With the above structure, the liquid storage module 500 does not need to be pre-installed in the foaming layer to avoid the adverse effects of the foaming process on the structure and performance of the liquid storage module 500, and the assembly process of the liquid storage module 500 can be performed in the storage space.
