In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Embodiments of the present invention provide a refrigerated chiller 10. Fig. 1 is a schematic block diagram of a refrigeration and freezer 10 according to one embodiment of the invention. Fig. 2 is a schematic block diagram of the refrigeration and freezer 10 of fig. 1 from another perspective. The refrigeration and freezer 10 may generally include a cabinet 100, a ventilation circuit 200, and an oxygen treatment device 300. The refrigerating and freezing device 10 according to the embodiment of the present invention may be a refrigerator, or may be a refrigerator, a freezer or a refrigerating apparatus having a low-temperature storage function, for example.

The interior of the housing 100 defines a compressor compartment 110 and a storage compartment 122. And the case 100 includes a foaming layer. For example, the case 100 may further include a liner 120 disposed inside the foaming layer, and the storage compartment 122 may be defined inside the liner 120. The foaming layer may be made of a heat insulating material such as polyurethane foam or the like.

The ventilation line 200 is embedded in the foaming layer and communicates the compressor compartment 110 and the storage compartment 122. The pre-embedding of the ventilation pipe 200 in the foam layer means that the ventilation pipe 200 is pre-positioned in the foam layer before the foam layer is formed, and is not installed after the foam layer is formed.

The oxygen treatment apparatus 300 is disposed in the compressor chamber 110 and is used for treating oxygen through an electrochemical reaction. The oxygen treatment apparatus 300 exchanges gas with the storage compartment 122 through the ventilation line 200 to adjust the oxygen content of the storage compartment 122 through an electrochemical reaction.

For example, a first end of the ventilation conduit 200 may be in communication with the compressor compartment 110, and a second end of the ventilation conduit 200 may be in communication with the storage compartment 122 and with an oxygen treatment device 300 disposed within the compressor compartment 110. Because oxygen treatment device 300 is disposed within compressor compartment 110, gas flowing through ventilation line 200 may flow to oxygen treatment device 300 to contact oxygen treatment device 300 or flow into the interior of oxygen treatment device 300; the gas generated by the oxygen treatment device 300 and/or the gas flowing through the oxygen treatment device 300 may flow into the ventilation line 200 to ventilate the storage space.

The direction of the flow of the gas flowing through the ventilation pipe 200 is not particularly limited in this embodiment. The gas flowing through the ventilation pipeline 200 may flow from the storage compartment 122 to the oxygen treatment device 300 or may flow from the oxygen treatment device 300 to the storage compartment 122, so that the storage compartment 122 and the oxygen treatment device 300 are ventilated. The electrochemical reaction of the oxygen treatment device 300 may consume oxygen. The gas in the storage compartment 122 may flow to the oxygen treatment device 300 through the ventilation line 200, so that oxygen in the gas may participate in an electrochemical reaction as a reactant to form a low-oxygen gas with reduced oxygen content. The low oxygen gas may be returned to the storage compartment 122 via the ventilation line 200 to reduce the oxygen content of the storage compartment 122. The electrochemical reaction of the oxygen treatment device 300 may also produce oxygen. The gas generated when the oxygen treatment apparatus 300 performs the electrochemical reaction may flow to the storage compartment 122 through the ventilation pipe 200, thereby increasing the oxygen content of the storage compartment 122.

For example, the refrigeration and freezing apparatus 10 may be preset with an air-conditioning fresh-keeping mode, and the oxygen treatment apparatus 300 may be operated when the air-conditioning fresh-keeping mode is started, for example, the oxygen treatment apparatus 300 is powered to perform an electrochemical reaction under the action of an electrolysis voltage, so as to adjust the oxygen content of the storage compartment 122.

By disposing the oxygen treatment device 300 in the compressor room 110 and embedding the ventilation duct 200 in the foaming layer, the ventilation duct 200 communicates the storage room 122 with the compressor room 110, and the ventilation duct 200 can be utilized to substantially match the air path barrier existing between the storage room 122 and the oxygen treatment device 300 disposed in the compressor room 110. With the above scheme, the invention creatively opens up an air conditioning path for communicating the storage compartment 122 with the compressor compartment 110, so that the oxygen content of the storage compartment 122 can be regulated by the oxygen treatment device 300 without affecting the volume ratio of the refrigeration and freezing device 10.

It should be emphasized that for controlled atmosphere, to facilitate the oxygen treatment device 300 to regulate the oxygen content of the compartment 122, one of ordinary skill in the art will readily recognize that the proximate principle may be employed to locate the oxygen treatment device 300 within the compartment 122, such as on the storage container 600, or on an interior wall of the compartment 122, which would compress the volumetric capacity of the refrigeration and freezer 10. The inventor of the present application creatively opens up an air conditioning path for communicating the storage compartment 122 with the compressor compartment 110, and installs the oxygen treatment device 300 in the compressor compartment 110, which breaks through the concept of the prior art, provides a new idea for realizing air conditioning fresh-keeping of the refrigeration and freezing device 10 under the condition of maintaining a higher volume rate, and solves a plurality of technical problems of higher damage rate and the like of the oxygen treatment device 300 due to easy access by objects.

Because the temperature of the compressor compartment 110 is relatively high, the oxygen treatment device 300 disposed within the compressor compartment 110 can maintain a relatively high electrochemical reaction rate, which is advantageous for improving the air conditioning efficiency of the refrigeration chiller 10.

In some alternative embodiments, the bottom of the compressor compartment 110 is provided with a support plate 111 for securing the compressor. The oxygen treatment device 300 is disposed on the support plate 111. In the present embodiment, the oxygen treatment device 300 may be directly or indirectly disposed on the support plate 111, which does not mean that the oxygen treatment device 300 is in direct contact with the support plate 111.

In one example, the space in which oxygen treatment device 300 is located may be spaced apart from the other spaces of compressor compartment 110 and used as a separate space to avoid gas exchange with the other spaces of compressor compartment 110.

In some alternative embodiments, the wall of the compressor compartment 110 is provided with a first aperture extending through the thickness thereof for inserting the first end of the ventilation conduit 200 into the compressor compartment 110, and the wall of the storage compartment 122 is provided with a second aperture extending through the thickness thereof for inserting the second end of the ventilation conduit 200 into the storage compartment 122, thereby securing the ventilation conduit 200.

In one example, a first annular protrusion protruding outwards and abutting against the edge of the first light hole is encircling the pipe wall of the first end of the ventilation pipe 200, so as to prevent the first end of the ventilation pipe 200 from falling out of the first light hole; the second annular protrusion protruding outwards and propping against the edge of the second light hole can be encircling the pipe wall of the second end of the ventilation pipeline 200 so as to prevent the second end of the ventilation pipeline 200 from falling out of the second light hole.

Of course, in other examples, other means may be used to prevent the first end of the ventilation circuit 200 from exiting the first aperture and to prevent the second end of the ventilation circuit 200 from exiting the second aperture. For example, a first convex claw protruding outward and abutting against the edge of the first light hole may be formed on the wall of the first end of the ventilation pipe 200, and a second convex claw protruding outward and abutting against the edge of the second light hole may be formed on the wall of the second end of the ventilation pipe 200.

With the above structure, misalignment of the ventilation pipeline 200 can be reduced or avoided during the foaming layer forming process, so that the air flow channel between the storage compartment 122 and the compressor compartment 110 is kept smooth.

The compressor compartment 110 may be disposed below the storage compartment 122. For example, the compressor compartment 110 may be disposed at a lower rear side of the storage compartment 122. The first light aperture may be provided on a top wall of the compressor compartment 110. A second light aperture may be provided in the back wall of the storage compartment 122 and the ventilation conduit 200 extends from the back of the storage compartment 122 down to the top of the compressor compartment 110.

Of course, in other embodiments, compressor compartment 110 may be disposed above storage compartment 122. For example, the compressor compartment 110 may be disposed above and rearward of the storage compartment 122. The first light aperture may be provided on the bottom wall of the compressor compartment 110. The second light aperture may be disposed on the back wall of the storage compartment 122, and the ventilation duct 200 extends upward from the back of the storage compartment 122 to the bottom of the compressor compartment 110.

In some alternative embodiments, oxygen treatment device 300 has a ventilation chamber for communicating with ventilation line 200 and defining a gas flow space, and an electrochemical reaction chamber for communicating with the gas flow space and for regulating the oxygen content of the gas flow space by performing an electrochemical reaction. The ventilation chamber has a ventilation opening communicating with the airflow space.

The refrigeration and freezer 10 also includes a first connecting conduit 410 connected between the first end of the ventilation conduit 200 and the ventilation port of the ventilation chamber to indirectly communicate the ventilation conduit 200 with the airflow space of the ventilation chamber.

By providing the first connecting pipe 410, the gas from the storage compartment 122 can be directionally conveyed to the ventilation chamber of the oxygen treatment device 300 under the guidance of the first connecting pipe 410, so that the gas is intensively treated in the ventilation chamber, and the treated gas can be introduced into the storage compartment 122, so that the ventilation of the storage compartment 122 is realized.

In some alternative embodiments, the electrochemical reaction chamber includes a housing 320, a cathode plate 330, and an anode plate 340. Fig. 3 is a schematic structural view of an electrochemical reaction chamber of an oxygen treatment device 300 of the refrigerating and freezing apparatus 10 according to an embodiment of the present invention. Fig. 4 is a schematic exploded view of an electrochemical reaction chamber of the oxygen treatment device 300 of the refrigerator-freezer 10 shown in fig. 3.

The housing 320 has a lateral opening 321, and the lateral opening 321 communicates with the airflow space. For example, the housing 320 may have a flat rectangular parallelepiped shape. The lateral opening 321 may be provided on any face of the housing 320, such as a top face, a bottom face, or a side face. In one example, the lateral opening 321 may be disposed on a face of the housing 320 where the area is greatest. In some alternative embodiments, oxygen treatment device 300 may further include a housing that is fastened to a side of housing 320 that is provided with lateral opening 321 to define, with housing 320, a gas flow space that communicates with cathode plate 330.

The cathode plate 330 is disposed at the lateral opening 321 to define an electrochemical reaction chamber for containing an electrolyte together with the case 320, and serves to consume oxygen in a gas flow space through an electrochemical reaction. The electrochemical reaction bin is a place where the cathode plate 330 and the anode plate 340 perform electrochemical reaction, and can contain alkaline electrolyte, such as 1mol/L NaOH, and the concentration of the alkaline electrolyte can be adjusted according to actual needs. Oxygen in the air may undergo a reduction reaction at the cathode plate 330, namely: o (O) ₂ +2H ₂ O+4e ^- →4OH ^- 。

The anode plate 340 and the cathode plate 330 are disposed in the electrochemical reaction chamber to be spaced apart from each other, and serve to supply reactants to the cathode plate 330 and generate oxygen through an electrochemical reaction. OH generated by cathode plate 330 ^- An oxidation reaction may occur at anode plate 340 and produce oxygen, namely: 4OH ^- →O ₂ +2H ₂ O+4e ^- 。

The above examples of electrochemical reactions with respect to the cathode plate 330 and the anode plate 340 are merely illustrative, and those skilled in the art should easily change the types of electrochemical reactions or develop the structure of the oxygen treatment device 300 suitable for other types of electrochemical reactions based on the above-described embodiments, and such changes and development should fall within the scope of the present invention.

By disposing the cathode plate 330 at the lateral opening 321 and making the lateral opening 321 communicate with the gas flow space of the gas exchange chamber, the cathode plate 330 can perform electrochemical reaction by using oxygen in the gas flow space as a reactant because the gas from the storage compartment 122 can be intensively transported to the gas flow space, so that the oxygen content of the gas flow space can be reduced under the action of the cathode plate 330, so that the gas from the storage compartment 122 is converted into low-oxygen gas with lower oxygen content. The low oxygen gas may be delivered back into the storage compartment 122, thereby serving to reduce the oxygen content of the storage compartment 122.

In some alternative embodiments, the refrigerator-freezer 10 may further include a storage container 600 disposed within the storage compartment 122. The interior of the storage container 600 may define a storage space for storage. The wall of the storage container 600 is vented.

The refrigeration and freezer 10 also includes a second connecting conduit connected between the second end of the ventilation conduit 200 and the vent of the storage container 600 to indirectly communicate the ventilation conduit 200 with the storage compartment 122.

By providing the second connection line, the gas in the storage container 600 may be directionally transferred to the ventilation line 200 under the guidance of the second connection line and enter the ventilation chamber of the oxygen treatment device 300 under the guidance of the ventilation line 200, thereby being intensively treated in the ventilation chamber.

In the above embodiment, the ventilation pipeline 200 may be two and include the intake pipeline 210 and the return pipeline 220.

Accordingly, the number of the first light holes is two, and the first end of the air inlet pipeline 210 and the first end of the air return pipeline 220 are respectively inserted into the two light holes to realize fixation; the second light holes are two and are arranged at intervals, and are respectively used for inserting the second end of the air inlet pipeline 210 and the second end of the air return pipeline 220 to realize fixation.

The number of the scavenging ports is two, and the scavenging ports comprise a first scavenging port and a second scavenging port. The first ventilation port may be disposed on an upstream side of the plenum and the second ventilation port may be disposed on a downstream side of the plenum such that gas exiting the inlet line 210 may flow into the return line 220 after flowing through the cathode plate 330. Wherein the windward side and the leeward side are with respect to the gas flow path through the gas exchange chamber, the windward side is an upstream section of the gas flow path, and the leeward side is a downstream section of the gas flow path. The first connecting lines 410 are two, one of which is connected between the first end of the intake line 210 and the first transfer port of the transfer chamber and the other of which is connected between the first end of the return line 220 and the second transfer port of the transfer chamber. The number of the air vents is two, and the air vents comprise a first air vent and a second air vent. The second connecting pipes are two, one of which is connected between the second end of the air inlet pipe 210 and the first air vent, and the other of which is connected between the second end of the air return pipe 220 and the second air vent.

With the above structure, the air inlet pipe 210 and the air return pipe 220 are used to communicate the storage container 600 and the oxygen treatment device 300, so that an air flow circulation is formed between the storage space and the oxygen treatment device 300. The gas with higher oxygen content in the storage space can flow to the cathode plate 330 through the air inlet pipeline 210, so that the cathode plate 330 uses oxygen in the gas as a reactant to perform electrochemical reaction to form low-oxygen gas with lower oxygen content, and the low-oxygen gas can return to the storage space through the air return pipeline 220, thereby playing a role in reducing the oxygen content in the storage space.

In other alternative embodiments, the ventilation circuit 200 may be one. Accordingly, the first light hole, the second light hole, the first connecting pipeline 410 and the second connecting pipeline may be one. The case 320 has an exhaust hole 323 communicating with the electrochemical reaction chamber for exhausting oxygen generated from the anode plate 340. The first end of the ventilation pipe 200 may communicate with the exhaust hole 323 of the case 320, and the ventilation pipe 200 serves to guide oxygen generated from the anode plate 340 to the storage space, so that the storage space creates a high oxygen atmosphere.

In yet another example, a first end of the ventilation line 200 may communicate with a second ventilation port of the ventilation chamber, and the ventilation line 200 is configured to deliver a reduced oxygen gas having a reduced oxygen content flowing through the cathode plate 330 to the storage space to create a reduced oxygen atmosphere in the storage space. At this time, the first ventilation opening of the ventilation chamber may communicate with the external environment of the ventilation chamber for allowing gas from the external environment thereof to flow into the gas flow space.

In some alternative embodiments, the housing 320 is provided with a fluid refill port 322 that communicates with the electrochemical reaction cartridge.

Fig. 5 is a schematic block diagram of a refrigerating and freezing apparatus 10 according to another embodiment of the present invention. The refrigeration and freezing apparatus 10 further includes a liquid storage module 500 having a case 510, wherein a liquid storage space for storing liquid is defined inside the case 510, and the liquid storage space communicates with the liquid supplementing port 322 to supplement the electrolyte to the oxygen treatment apparatus 300. The liquid in the liquid storage space can be water or electrolyte, and the concentration of the liquid can be lower than that of the electrolyte in the electrochemical reaction bin.

In one example, the cartridge 510 is disposed within a foaming layer. By disposing the case 510 of the liquid storage module 500 in the foaming layer and making the liquid storage space of the case 510 in fluid communication with the oxygen treatment device 300, the liquid stored in the case 510 is used to supplement the electrolyte to the oxygen treatment device 300, and the refrigerating and freezing device 10 can supplement the electrolyte to the oxygen treatment device 300 by using the liquid storage module 500 without affecting the volume ratio, so that the oxygen treatment device 300 can continuously adjust the oxygen content in the storage space.

The case 510 of the liquid storage module 500 may be disposed at any portion of the foaming layer, for example, at a side portion of the inner container 120, or at a top portion, a bottom portion, and a back portion of the inner container 120. For a french refrigerator or a T-type refrigerator, in one example, the case 510 of the liquid storage module 500 may be disposed in a gap between an upper liner and a lower liner.

In some alternative embodiments, the case 100 further has a case 170, and the foaming layer is formed between the case 170 and the inner container. The case 170 covers the outer side of the foaming layer to clamp the foaming layer with the liner.

Fig. 6 is a schematic structural view of the liner 120 of the refrigerating and freezing apparatus 10 shown in fig. 5. The inner container 120 is provided with an opening-shaped interaction window 124, and the foaming layer is provided with an installation groove communicated with the interaction window 124 for assembling the liquid storage module 500. After the foaming layer is molded, the liquid storage module 500 may be fitted into the installation groove so as to be disposed in the foaming layer. The mounting groove can be reserved in the foaming layer forming process. The mounting groove is recessed in a thickness direction of the foaming layer toward a direction away from the interactive window 124, and forms a gap with the case 170. In other words, the mounting groove does not penetrate the foaming layer, so that the liquid storage module 500 fitted to the mounting groove does not cling to the case 170. That is, a certain thickness of heat insulating material is formed between the case 170 and the oxygen treatment device 300.

By adopting the structure, the liquid storage module 500 does not need to be preloaded in the foaming layer, the adverse effect on the structure and performance of the liquid storage module 500 in the foaming process is avoided, the assembly process of the liquid storage module 500 can be executed in the storage space, and the liquid storage module has the advantages of being simple in assembly process and the like.

By providing the interactive window 124 on the inner container 120 and providing the installation groove communicated with the interactive window 124 in the foaming layer, and forming a gap between the installation groove and the case 170, the liquid storage module 500 can be installed in the installation groove after the foaming layer is formed, which is beneficial to simplifying the disassembly and assembly difficulty of the liquid storage module 500. And because the mounting groove does not penetrate through the foaming layer, the solution of the embodiment can reduce or avoid the obvious reduction of the heat insulation performance of the refrigeration and freezing device 10 caused by the mounting of the liquid storage module 500 in the foaming layer.

The reservoir module 500 may be secured within the mounting recess by, but not limited to, bolting, clamping, riveting, welding, and bonding.

In some alternative embodiments, the case 510 is provided with a filling port 514 communicating with the liquid storage space, and the filling port 514 is exposed through the interaction window 124, so as to allow the external liquid to be filled into the liquid storage space. Fig. 7 is a schematic perspective view of a reservoir module 500 of the refrigeration and freezer 10 shown in fig. 5. For example, the filling port 514 is disposed on a side wall of the case 510 facing the storage space, so as to be exposed through the interaction window 124.

By providing the interactive window 124 on the liner 120 and enabling the liquid injection port 514 of the box 510 to communicate with the storage space through the interactive window 124, the interactive window 124 can be used as an operation window for supplementing liquid to the storage space by a user. Because the interaction window 124 can expose the liquid filling port 514, when the liquid storage amount in the liquid storage space is insufficient, the external liquid can be filled into the liquid storage space through the liquid filling port 514, so that the solution filling mode of the liquid storage module 500 can be simplified according to the above scheme of the embodiment, and the liquid storage module 500 can continuously fill the electrolyte into the oxygen treatment device 300.

The cover 550 is disposed on the box 510, and the cover 550 is reciprocally disposed at the filling port 514 to open or close the filling port 514. When the cap 550 opens the filling port 514, the filling port 514 is allowed to be exposed. By providing the cover 550 on the case 510 and opening or closing the liquid filling port 514 with the cover 550, the liquid filling port 514 is opened only when receiving external liquid, thereby reducing or preventing foreign matters from entering the liquid storage space and keeping the liquid stored in the liquid storage space clean.

The cover 550 may be a push-type flip-top that is rotatably sprung under pressure to extend at least partially into the storage space through the interactive window 124 to open the fill port 514.

In one example, the bottom of the cover 550 may be coupled to the case 510 by a hinge and pivotably coupled to the case 510. When the cover 550 closes the filling port 514, the outer surface of the cover is coplanar with the outer surface of the case 510, and at this time, the top of the cover 550 may be connected to the case 510 through a clamping structure; when the filling port 514 needs to be opened, the top of the cover 550 may be pressed to separate the top of the cover 550 from the box 510, and at this time, the cover 550 may rotate around the rotation axis and at least partially extend into the storage space, so as to open the filling port 514.

Those skilled in the art should readily know the assembly structure between the push-type flip cover and the case 510 based on the understanding of the embodiments of the present disclosure, and the disclosure will not be repeated.

In some alternative embodiments, at least a portion of the cartridge 510 is made of a transparent material to form a viewable area 516 for revealing the stored fluid volume of the cartridge 510. The transparent material may be polymethyl methacrylate, polycarbonate, polyethylene terephthalate, polypropylene, or the like.

The viewable area 516 of the present embodiment is revealed through the interactive window 124. The visible area 516 is disposed to extend longitudinally and is located below the filling port 514. For example, the viewable area 516 is also disposed on a side wall of the box 510 facing the storage space to be exposed through the interactive window 124.

By providing the viewable area 516 on the cartridge 510 with the viewable area 516 opposite the interactive window 124, the interactive window 124 may be utilized as a viewing window for a user to view the liquid level in the liquid storage space. Because the interaction window 124 can expose the visible area 516, the user can very conveniently observe the liquid storage amount of the liquid storage space, so the above scheme of the embodiment can enable the user to obtain visual interaction experience. When the liquid storage volume of the liquid storage space is insufficient, the user can timely take liquid supplementing measures.

In one example, the interactive window 124 may be located on a sidewall of the liner 120, with the mounting groove being disposed between the sidewall of the liner 120 and the sidewall of the case 170, respectively.

Because the side wall of the liner 120 is not easy to be shielded by the articles stored in the storage space and is closer to the movable area of the user, the interactive window 124 is arranged on the side wall of the liner 120, and the liquid storage module 500 is embedded into the foaming layer at the side part of the box body 100, so that the interaction difficulty between the user and the liquid storage module 500 can be reduced to a certain extent, the user can quickly acquire the liquid storage amount information of the liquid storage module 500 without moving the articles stored in the storage space, and the liquid supplementing operation can be timely performed when the liquid storage amount of the liquid storage module 500 is insufficient.

In some alternative embodiments, the fluid storage module 500 may further include a fluid level sensor disposed within the fluid storage space and configured to detect a fluid level in the fluid storage space. When the liquid level sensor detects that the liquid level in the liquid storage space is lower than the set value, the refrigerating and freezing device 10 can send an alarm signal, for example, the alarm signal can be transmitted to a user through a wireless transmission technology, so as to remind the user of timely liquid supplementing.

In some further examples, the case 510 has a first side wall that is flush with the side wall of the inner container 120 and closes the interactive window 124, and a second side wall opposite the first side wall and hidden inside the mounting groove. The filling port 514 is located on the first sidewall. The opening area of the interaction window 124 may be substantially the same as the surface area of the first sidewall of the case 510, so that the first sidewall of the case 510 just closes the interaction window 124 and the outer surface of the first sidewall is connected with the inner surface of the sidewall of the liner 120 to form a complete plane, so that the appearance is attractive.

The fill port 514 may be disposed in an upper section of the first sidewall. The viewing area may also be provided on the first side wall, for example on a middle section or a lower section of the first side wall.

The case 510 may have a substantially flat rectangular parallelepiped shape. The box 510 is provided with a liquid outlet 511 communicated with the liquid storage space. The case 510 further has top and bottom walls connected between the first and second sidewalls and disposed opposite in a vertical direction. The bottom wall is provided with a liquid outlet 511, and the liquid outlet 511 is communicated with a liquid supplementing port 322 so as to supplement electrolyte to the electrochemical reaction bin.

The refrigeration and freezing device 10 further comprises a liquid supplementing pipeline pre-buried in the foaming layer, wherein a first end of the liquid supplementing pipeline is communicated with the liquid supplementing port 322 of the oxygen treatment device 300, and a second end of the liquid supplementing pipeline is communicated with the liquid outlet 511 of the liquid storage module 500, so that liquid flowing out of the liquid storage space from the liquid outlet 511 is guided to the liquid supplementing port 322, and liquid is supplemented to the electrochemical reaction bin. The liquid outlet 511 is higher than the liquid supplementing inlet 322, so that the liquid in the liquid storage space can automatically flow into the electrochemical reaction bin under the action of gravity without a power device.

Of course, in other examples, the outlet 511 may be lower than the fluid-filling port 322 or be level with the fluid-filling port 322. At this time, a pump can be arranged on the liquid supplementing pipeline so as to drive the liquid in the liquid storage space to flow into the electrochemical reaction bin under the action of the pump; or the liquid in the liquid storage space can flow into the electrochemical reaction bin by utilizing the siphon principle.

In some further examples, a one-way valve may be provided on the fluid-filled line for allowing one-way passage of fluid from the outlet 511, ensuring one-way flow of fluid through the fluid-filled line.

In some alternative embodiments, the housing 320 has an exhaust hole 323 in communication with the electrochemical reaction chamber for exhausting oxygen generated by the anode plate 340. The top wall of the box 510 is provided with an air inlet 512 and an air outlet 513, wherein the air inlet 512 is communicated with the air outlet 323 of the oxygen treatment device 300, so as to allow oxygen discharged from the air outlet 323 to be introduced into the liquid storage space to filter soluble impurities, such as electrolyte carried by the oxygen. The air outlet 513 is used to allow the filtered oxygen to be discharged outwards.

The refrigerating and freezing device 10 further comprises a filtering pipeline pre-buried in the foaming layer, wherein a first end of the filtering pipeline is communicated with the air outlet 323 of the oxygen treatment device 300, and a second end of the filtering pipeline is communicated with the air inlet 512 of the box body 510 so as to guide oxygen flowing out from the air outlet 323 to the air outlet 513, so that the oxygen enters the liquid storage space for filtering.

The reservoir module 500 may further include a filter tube 540 and an outlet tube. Wherein the air filter tube 540 is inserted into the liquid storage space from the air inlet 512 and extends to the bottom section of the liquid storage space to guide the oxygen to be filtered to the liquid storage space, so that the soluble impurities in the oxygen are dissolved in the liquid storage space. The outlet pipe is inserted into the box 510 from the outlet 513, extends to the upper section of the liquid storage space, and is positioned above the liquid stored in the liquid storage space so as to guide the filtered oxygen out therethrough.

By adopting the above scheme, the oxygen to be filtered can reach the liquid storage space under the guidance of the air filtering pipe 540 and flow through the liquid stored in the liquid storage space, so that the soluble impurities in the oxygen are dissolved in the liquid storage space, and the purification of the gas is completed. The purified gas can flow into the appointed space under the guidance of the air outlet pipe, thereby playing the role of adjusting the oxygen content in the space.

In an alternative embodiment, the liquid storage module 500 further includes an air blocking mechanism 530 disposed in the liquid storage space and separating the liquid storage space into an air filtering area and a non-air filtering area with blocked air paths. Wherein the gas filtering section is for allowing the gas flowing into the gas inlet 512 to flow therethrough to achieve filtering. The non-air filtering area is used for receiving liquid from outside.

The air filtering area and the non-air filtering area can be arranged in parallel along the transverse direction, and the air blocking mechanism 530 blocks a part of the liquid path between the air filtering area and the non-air filtering area, so that the air filtering area and the non-air filtering area keep the liquid path communicated under the condition that the air path is blocked. For example, the air blocking mechanism 530 is a partition-like structure located between the air filtering region and the non-air filtering region and extending downward from the lower surface of the top wall of the box 510 and forming a gap with the upper surface of the bottom wall of the box 510. The air filtering area is located at one lateral side of the air blocking mechanism 530, and the non-air filtering area is located at the other lateral side of the air blocking mechanism 530. The air inlet 512 and the air outlet 513 may be respectively provided on the top wall of the region where the air filtering region is located. The filling port 514 may be disposed on the top wall of the non-air filtering area.

With the above structure, by providing the air-blocking mechanism 530 in the liquid storage space and separating the liquid storage space into the air filtering area and the non-air filtering area, which are blocked by the air-blocking mechanism 530, the function of purifying the air can be realized only in the air filtering area. Because the air filtering area is only a subspace of the liquid storage space and is blocked from the air passage between other areas of the liquid storage space, the air introduced into the air inlet 512 can only flow in the air filtering area, and can not be freely diffused to the non-air filtering area, so that the air can not be rapidly discharged, and the liquid storage module 500 of the embodiment has a higher purified air release rate.

In some alternative embodiments, the case 510 further has third and fourth sidewalls connected between the first and second sidewalls and disposed opposite in a horizontal direction. The outer surface of the third and/or fourth side wall is coupled with a fixing member 517, and the fixing member 517 has a screw hole for cooperating with a screw to fix the cartridge 510 to the mounting groove.

In the above embodiment, the storage compartment 122 may be a refrigerating compartment for refrigerating articles. In one example, the housing 100 also defines another storage compartment 132, such as a temperature change compartment or a freezer compartment, although it may be a sub-zero compartment. The refrigerating and freezing device 10 further comprises an oxygen delivery pipeline pre-buried in the foaming layer, which is communicated with the air outlet 513 and the other storage compartment 132 to deliver oxygen to the other storage compartment 132, thereby creating a high-oxygen fresh-keeping atmosphere and improving the fresh-keeping performance of the refrigerating and freezing device 10.

In some further examples, the oxygen transfer line may also be provided with a one-way valve for allowing one-way passage of oxygen to the other storage compartment 132, ensuring one-way flow of gas through the oxygen transfer line.
