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

An embodiment of the utility model provides a cold-stored refrigeration device 10. Fig. 1 is a schematic structural view of a refrigeration and freezing apparatus 10 according to an embodiment of the present invention. Fig. 2 is a schematic configuration diagram of another view of the refrigeration and freezing apparatus 10 shown in fig. 1. The refrigeration chiller 10 may generally include a tank 100, a ventilation circuit 200, and an oxygen treatment device 300. The utility model discloses cold-stored refrigerating plant 10 can be the refrigerator, also can be for freezer, freezer or freezer etc. possess the refrigeration plant of low temperature storage function.

The interior of the chest 100 defines a compressor compartment 110 and a storage compartment 122. And the cabinet 100 includes a foamed layer. For example, the container 100 may further include an inner container 120 disposed inside the foaming layer, and the inner side of the inner container 120 may define a storage compartment 122. The foamed layer may be made of heat insulating material such as polyurethane foam or the like.

The ventilation pipeline 200 is pre-embedded in the foaming layer and communicates the compressor chamber 110 and the storage chamber 122. The ventilation pipeline 200 is embedded in the foaming layer, which means that the ventilation pipeline 200 is positioned in the foaming layer before the foaming layer is formed, and is not installed after the foaming layer is formed.

The oxygen treatment device 300 is disposed in the compressor room 110, and is used to treat oxygen through an electrochemical reaction. The oxygen processing device 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 line 200 may be connected to the compressor chamber 110, and a second end of the ventilation line 200 may be connected to the storage chamber 122 and to the oxygen treatment device 300 disposed in the compressor chamber 110. Since the oxygen treatment device 300 is disposed in the compressor room 110, the gas flowing through the ventilation line 200 may flow to the oxygen treatment device 300 to contact the oxygen treatment device 300 or flow into the oxygen treatment device 300; the gas generated by the oxygen treatment device 300 and/or the gas flowing through the oxygen treatment device 300 can flow into the ventilation line 200 in order to ventilate the storage space.

The present embodiment is not particularly limited to the flow direction of the gas flowing through the ventilation pipeline 200. The gas flowing through the ventilation pipeline 200 may flow from the storage chamber 122 to the oxygen processing device 300, or may flow from the oxygen processing device 300 to the storage chamber 122, so that the storage chamber 122 and the oxygen processing device 300 are ventilated. The electrochemical reaction of oxygen treatment device 300 may consume oxygen. The gas in the storage chamber 122 can flow to the oxygen processing device 300 through the ventilation pipeline 200, so that the oxygen in the gas participates in the electrochemical reaction as a reactant to form low-oxygen gas with reduced oxygen content. The hypoxic gas can 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 oxygen processing device 300 may also generate oxygen. The gas generated by the electrochemical reaction of the oxygen processing device 300 can flow to the storage chamber 122 through the ventilation pipeline 200, so as to increase the oxygen content of the storage chamber 122.

For example, the refrigerator-freezer 10 may be preset with a modified atmosphere mode, and when the modified atmosphere mode is activated, the oxygen treatment device 300 may be operated, for example, the oxygen treatment device 300 may be powered to perform an electrochemical reaction under the action of an electrolytic voltage, so as to adjust the oxygen content of the storage compartment 122.

By installing the oxygen treatment device 300 in the compressor chamber 110 and embedding the ventilation pipeline 200 in the foaming layer, the ventilation pipeline 200 communicates the storage chamber 122 with the compressor chamber 110, and the ventilation pipeline 200 can be utilized to be substantially identical to the gas path barrier existing between the storage chamber 122 and the oxygen treatment device 300 installed in the compressor chamber 110. With the above technical scheme, the utility model discloses creatively opened up the gas regulation route of intercommunication storing room 122 and compressor room 110, made cold-stored refrigerating plant 10 under the condition that does not influence the plot ratio, utilized oxygen processing apparatus 300 to adjust the oxygen content of storing room 122.

It is emphasized that for modified atmosphere preservation, in order to facilitate the oxygen treatment device 300 to regulate the oxygen content of the storage compartment 122, one of ordinary skill in the art will readily recognize that the placement of the oxygen treatment device 300 within the storage compartment 122, such as on the storage container 600, or on the interior wall of the storage compartment 122, all would compress the volume fraction of the refrigeration and freezing apparatus 10, using the present principles. The inventor of the present application breaks through the limitation of the prior art by creatively opening a modified atmosphere path for communicating the storage compartment 122 and the compressor compartment 110, and installing the oxygen treatment device 300 in the compressor compartment 110, thereby providing a new idea for the refrigerator-freezer 10 to achieve modified atmosphere preservation while maintaining a high volume ratio, and simultaneously solving a plurality of technical problems that the oxygen treatment device 300 is easily touched by articles and has a high damage ratio, and the like.

Because the temperature of the compressor chamber 110 is high, the oxygen treatment device 300 disposed in the compressor chamber 110 can maintain a high electrochemical reaction rate, which is beneficial to improving the air conditioning efficiency of the refrigeration and freezing device 10.

In some alternative embodiments, the bottom of the compressor chamber 110 is provided with a support plate 111 for fixing the compressor. The oxygen processing device 300 is disposed on the support plate 111. In this embodiment, the oxygen treatment device 300 may be directly or indirectly disposed on the support plate 111, and it is not meant that the oxygen treatment device 300 is in direct contact with the support plate 111.

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

In some optional embodiments, a first light hole penetrating through the thickness direction of the compressor chamber 110 is formed on the wall of the compressor chamber 110, so that the first end of the ventilation pipeline 200 is inserted into the compressor chamber 110 through the first light hole, and a second light hole penetrating through the thickness direction of the storage chamber 122 is formed on the wall of the storage chamber 122, so that the second end of the ventilation pipeline 200 is inserted into the storage chamber 122 through the second light hole, thereby fixing the ventilation pipeline 200.

In one example, a first annular protrusion protruding outward and abutting against an edge of the first aperture is surrounded on a tube wall of the first end of the ventilation tube 200 to prevent the first end of the ventilation tube 200 from coming out of the first aperture; a second annular protrusion protruding outwards and abutting against the edge of the second light hole may be surrounded on the tube wall of the second end of the ventilation tube 200 to prevent the second end of the ventilation tube 200 from coming out of the second light hole.

In other examples, the first end of the ventilation pipe 200 can be prevented from coming out of the first aperture, and the second end of the ventilation pipe 200 can be prevented from coming out of the second aperture. For example, a first outward protruding claw protruding outward and abutting against the edge of the first unthreaded hole may be formed on the tube wall of the first end of the ventilation tube 200, and a second outward protruding claw protruding outward and abutting against the edge of the second unthreaded hole may be formed on the tube wall of the second end of the ventilation tube 200.

By adopting the structure, the dislocation of the ventilation pipeline 200 can be reduced or avoided in 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 hole may be provided on a top wall of the compressor compartment 110. A second light hole may be provided on the back wall of the storage compartment 122 and the ventilation tubing 200 extends from the back of the storage compartment 122 down to the top of the compressor compartment 110.

Of course, in other embodiments, the compressor compartment 110 may be disposed above the storage compartment 122. For example, the compressor compartment 110 may be disposed above and behind the stowage compartment 122. The first light hole may be disposed on a bottom wall of the compressor compartment 110. The second light hole may be disposed on a back wall of the storage compartment 122, and the ventilation tubing 200 extends upward from the back of the storage compartment 122 to the bottom of the compressor compartment 110.

In some alternative embodiments, the oxygen processing device 300 has a ventilation chamber for communicating with the ventilation conduit 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 is provided with a ventilation opening communicated with the airflow space.

The refrigerating-freezing device 10 further comprises a first connecting line 410 which is connected between the first end of the ventilation line 200 and the ventilation opening of the ventilation chamber so that the ventilation line 200 is indirectly in communication with the air flow space of the ventilation chamber.

By providing the first connecting line 410, the gas from the storage compartment 122 can be directionally conveyed to the ventilation chamber of the oxygen processing device 300 under the guidance of the first connecting line 410, so as to be centrally processed in the ventilation chamber, and the processed gas can be introduced into the storage compartment 122, so as to ventilate the storage compartment 122.

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 apparatus 300 of the refrigerating and freezing apparatus 10 according to an embodiment of the present invention. Fig. 4 is a schematic exploded view of the electrochemical reaction chamber of the oxygen processing device 300 of the refrigeration and freezing apparatus 10 shown in fig. 3.

The housing 320 has a lateral opening 321, the lateral opening 321 communicating 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 side of the housing 320, such as a top, bottom, or side surface. In one example, the lateral opening 321 may be disposed on a face of the housing 320 having the largest area. In some alternative embodiments, the oxygen treatment device 300 may further include a cover covering the side of the casing 320 with the lateral opening 321 to define an air flow space communicating with the cathode plate 330 together with the casing 320.

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

The anode plate 340 and the cathode plate 330 are disposed in the electrochemical reaction chamber in a spaced manner, and are used for providing reactant to the cathode plate 330 through electrochemical reaction and generating oxygen. OH generated from the cathode plate 330 ^- An oxidation reaction may occur at the anode plate 340 and oxygen is generated, i.e.: 4OH ^- →O ₂ +2H ₂ O+4e ^- 。

The above examples of electrochemical reactions of the cathode plate 330 and the anode plate 340 are merely illustrative, and based on the understanding of the above embodiments, those skilled in the art should easily change the type of electrochemical reaction or expand the structure of the oxygen treatment device 300 suitable for other types of electrochemical reactions, and such changes and expansions should fall within the scope of the present invention.

By arranging the cathode plate 330 at the lateral opening 321 and communicating the lateral opening 321 with the air flow space of the ventilation chamber, since the gas from the storage compartment 122 can be intensively delivered to the air flow space, the cathode plate 330 can utilize the oxygen in the air flow space as a reactant to perform an electrochemical reaction, and therefore, under the action of the cathode plate 330, the oxygen content in the air flow space can be reduced, so that the gas from the storage compartment 122 is converted into a low-oxygen gas with a low oxygen content. The hypoxic gas can be delivered back into the storage compartment 122, thereby serving to reduce the oxygen content of the storage compartment 122.

In some optional embodiments, the refrigerating and freezing device 10 may further include a storage container 600 disposed in the storage compartment 122. The inside of the storage container 600 may define a storage space for storing articles. The wall of the storage container 600 is provided with a vent.

The refrigerating and freezing device 10 further includes a second connection line connected between the second end of the ventilation line 200 and the vent of the storage container 600 to indirectly communicate the ventilation line 200 with the storage compartment 122.

By providing the second connection line, the gas in the storage container 600 can be directionally conveyed 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, so as to be intensively treated in the ventilation chamber.

In the above embodiment, the ventilation circuit 200 may be two, and includes an air intake circuit 210 and an air return circuit 220.

Correspondingly, there are two first light holes, into which the first end of the air inlet pipeline 210 and the first end of the air return pipeline 220 are respectively inserted to realize fixation; the two second light holes are arranged at intervals, and the second end of the air inlet pipeline 210 and the second end of the air return pipeline 220 are respectively inserted into the two second light holes to realize fixation.

The transfer ports are two and include a first transfer port and a second transfer port. A first transfer port may be provided on the upstream side of the transfer chamber and a second transfer port may be provided on the downstream side of the transfer chamber so that gas flowing out of the inlet line 210 may flow into the return line 220 after flowing through the cathode plate 330. Wherein the upwind side and the downwind side are relative to the gas flow path through the ventilation chamber, the upwind side refers to the upstream section of the gas flow path, and the downwind side refers to the 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 inlet line 210 and the first transfer ports of the transfer chambers and the other of which is connected between the first end of the return line 220 and the second transfer ports of the transfer chambers. The number of the vent holes is two, and the vent holes comprise a first vent hole and a second vent hole. The second connecting line is two, one of which is connected between the second end of the air intake line 210 and the first vent, and the other of which is connected between the second end of the return line 220 and the second vent.

With the above configuration, the air intake line 210 and the air return line 220 communicate the storage container 600 with the oxygen treatment device 300, so that air circulation can be 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 performs an electrochemical reaction by using the oxygen therein as a reactant 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 alternative embodiments, there may be one ventilation line 200. Accordingly, there may be one first light hole, one second light hole, one first connection pipe 410, and one second connection pipe. The housing 320 has an exhaust hole 323 communicating with the electrochemical reaction chamber for discharging oxygen generated from the anode plate 340. The first end of the ventilation pipe 200 can communicate with the exhaust hole 323 of the housing 320, and the ventilation pipe 200 is used to guide the oxygen generated by the anode plate 340 to the storage space, so that the storage space can create a high oxygen atmosphere.

In yet another example, the first end of the ventilation circuit 200 may be connected to the second ventilation port of the ventilation chamber, and the ventilation circuit 200 is used to deliver the low oxygen gas with low oxygen content flowing through the cathode plate 330 to the storage space, so as to create a low oxygen atmosphere in the storage space. In this case, the first transfer port of the transfer chamber may be in communication with the environment outside the transfer chamber for allowing gas from the environment outside thereof to flow into the gas flow space.

In some alternative embodiments, the housing 320 defines a fluid infusion port 322 in communication with the electrochemical reaction chamber.

Fig. 5 is a schematic structural view of a refrigerating and freezing apparatus 10 according to another embodiment of the present invention. The refrigeration and freezing device 10 further includes a reservoir module 500 having a case 510, the interior of the case 510 defining a reservoir space for storing liquid, the reservoir space communicating with the replenishment port 322 to replenish the oxygen treatment device 300 with electrolyte. The liquid contained in the liquid storage space can be water or electrolyte, and the concentration of the electrolyte can be lower than that of the electrolyte contained in the electrochemical reaction chamber.

In one example, cartridge 510 is disposed within a foam layer. Through setting up the box body 510 of stock solution module 500 in the foaming layer to make the stock solution space of box body 510 communicate with each other with oxygen processing apparatus 300 liquid way, with the liquid that utilizes box body 510 to store supplyes electrolyte to oxygen processing apparatus 300, because box body 510 does not occupy the storing space, consequently cold-stored refrigeration device 10 can utilize stock solution module 500 to supply electrolyte to oxygen processing apparatus 300 under the condition that does not influence the volume fraction, makes oxygen processing apparatus 300 sustainably adjust the oxygen content in storing space.

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

In some alternative embodiments, the enclosure 100 also has a shell 170, and a foam layer is formed between the shell 170 and the inner container. The case 170 covers the outer side of the foaming layer to sandwich the foaming layer with the inner container.

Fig. 6 is a schematic configuration diagram of the inner container 120 of the refrigeration and freezing apparatus 10 shown in fig. 5. The inner container 120 is opened with an open interactive window 124, and the foaming layer has a mounting groove communicated with the interactive 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 mounting groove so as to be disposed within the foaming layer. The mounting groove can be reserved in the forming process of the foaming layer. The mounting recess is recessed in the thickness direction of the foam layer toward a direction away from the interaction window 124, and forms a gap with the cabinet 170. In other words, the mounting recess does not extend through the foam layer, which prevents the reservoir module 500 fitted to the mounting recess from clinging to the housing 170. That is, a heat insulating material having a certain thickness is formed between the cabinet 170 and the oxygen treatment device 300.

By adopting the structure, the liquid storage module 500 is not required to be pre-installed in the foaming layer, the adverse effect of the foaming process on the structure and the performance of the liquid storage module 500 is avoided, the assembling process of the liquid storage module 500 can be executed in the storage space, and the liquid storage module has the advantages of simple assembling process and the like.

Through set up mutual window 124 on inner bag 120 to set up in the foaming layer with the communicating mounting groove of mutual window 124, and make and form the clearance between mounting groove and the case shell 170, stock solution module 500 can install to mounting groove again after the foaming layer shaping, this is favorable to simplifying the dismouting degree of difficulty of stock solution 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 preservation performance of the refrigeration and freezing device 10 caused by the installation of the liquid storage module 500 in the foaming layer.

The liquid storage module 500 can be fixed in the mounting groove by means of, but not limited to, screwing, clamping, riveting, welding and bonding.

In some alternative embodiments, the case 510 defines 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 external liquid to be filled into the liquid storage space. Fig. 7 is a schematic perspective view of the reservoir module 500 of the refrigerated refrigeration unit 10 shown in fig. 5. For example, the liquid injection port 514 is disposed on the sidewall of the box 510 facing the storage space to be exposed through the interaction window 124.

By opening the interactive window 124 on the inner container 120 and communicating the liquid injection port 514 of the box 510 with the storage space through the interactive window 124, the interactive window 124 can be used as an operation window for a user to replenish liquid into the storage space. Because mutual window 124 can expose annotating liquid mouth 514, when the stock solution volume of stock solution space was not enough, outside liquid can pour into the stock solution space into through annotating liquid mouth 514, consequently, the above-mentioned scheme of this embodiment can simplify stock solution module 500's fluid infusion mode, makes stock solution module 500 sustainable replenishment electrolyte to oxygen processing apparatus 300.

The case 510 is provided with a lid 550, and the lid 550 is reciprocatingly provided at the pouring outlet 514 to open or close the pouring outlet 514. When the lid 550 opens the pouring outlet 514, the pouring outlet 514 is allowed to be exposed. Through set up lid 550 on box body 510 to utilize lid 550 to open or seal and annotate liquid mouth 514, can make and annotate liquid mouth 514 and be open state when only receiving outside liquid, thereby reducible or avoid the foreign matter to get into stock solution space, make the liquid that stock solution space was stored keep clean.

The cover 550 may be a push-type flip cover that is pushed to pivotally flip up to at least partially extend into the storage space via the interactive window 124 to open the pour opening 514.

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

Based on the understanding of the embodiments of the present disclosure, a person skilled in the art should easily know the assembling structure between the push type flip cover and the box 510, and the detailed description of the present disclosure is omitted.

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 amount of fluid reservoir of the cartridge 510. The transparent material can be polymethyl methacrylate, polycarbonate, polyethylene terephthalate or polypropylene, etc.

The viewable area 516 of the present embodiment is exposed through the interactive window 124. The visual area 516 is disposed to extend in the longitudinal direction and is located below the pouring outlet 514. For example, the viewing area 516 is also disposed on the sidewall of the box 510 facing the storage space so as to be exposed through the interactive window 124.

By providing a viewing area 516 on the cartridge 510, and having the viewing area 516 opposite the interactive window 124, the interactive window 124 can be used as a viewing window for a user to view the level of the reservoir. Because the visible area 516 can be exposed through the interactive window 124, the user can very conveniently observe the liquid storage amount of the liquid storage space, and therefore, the above scheme of the embodiment can enable the user to obtain intuitive interactive experience. When the stock solution volume of stock solution space is not enough, the user can take fluid replacement measure in time.

In one example, the interaction window 124 can be located on a sidewall of the inner container 120, with the mounting recess correspondingly disposed between the sidewall of the inner container 120 and the sidewall of the housing 170.

Because the lateral wall of inner bag 120 is difficult for being sheltered from by the article that storage space stored, and it is nearer with user's movable region distance, consequently, set up mutual window 124 on the lateral wall of inner bag 120, and make stock solution module 500 imbed in the foaming layer of box 100 lateral part, can reduce the mutual degree of difficulty between user and stock solution module 500 to a certain extent, the user need not to move the article that storage space stored alright promptly with acquire stock solution volume information of stock solution module 500, and can in time carry out the fluid infusion operation when stock solution module 500's stock solution volume is not enough.

In some alternative embodiments, the reservoir module 500 may further include a level sensor disposed within the reservoir and configured to detect a level of the reservoir. When the liquid level sensor detects that the liquid level in the liquid storage space is lower than the set value, the refrigeration 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 replenishment.

In some further examples, the box 510 has a first sidewall that is flush with a sidewall of the inner bladder 120 and encloses the interaction window 124, and a second sidewall opposite the first sidewall and hidden inside the mounting groove. The pour spout 514 is located on the first side wall. The open area of interaction window 124 and the surface area of the first sidewall of case 510 may be substantially the same, such that the first sidewall of case 510 just closes interaction window 124 and the outer surface of the first sidewall is connected to the inner surface of the sidewall of inner container 120 to form a complete plane, thereby providing an aesthetic appearance.

The pour spout 514 may be disposed in an upper section of the first sidewall. The viewing area may also be disposed on the first sidewall, for example, in a middle section or a lower section of the first sidewall.

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

The refrigerating and freezing device 10 further includes a liquid supplementing pipeline pre-embedded in the foam layer, a first end of the liquid supplementing pipeline is communicated with the liquid supplementing port 322 of the oxygen processing 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 the liquid flowing out of the liquid storage space from the liquid outlet 511 is guided to the liquid supplementing port 322, and the liquid is supplemented to the electrochemical reaction chamber. The liquid outlet 511 is higher than the liquid replenishing opening 322, so that the liquid in the liquid storage space can automatically flow into the electrochemical reaction chamber under the action of gravity without a power device.

Of course, in other examples, outlet 511 may be shifted lower than fluid infusion port 322 or even with fluid infusion port 322. At the moment, 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 cabin by utilizing the siphon principle.

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

In some alternative embodiments, the housing 320 has an exhaust hole 323 communicating with the electrochemical reaction chamber for exhausting oxygen generated from 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 to allow the oxygen discharged from the air outlet 323 to pass into the liquid storage space to filter the soluble impurities, such as the electrolyte carried by the oxygen. The gas outlet 513 is used for allowing the filtered oxygen to be discharged outwards.

The refrigerating and freezing device 10 further includes a filtering pipeline pre-embedded in the foam layer, 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 510, so as to guide the oxygen flowing out from the air outlet 323 to the air outlet 513, and then the oxygen enters the liquid storage space for filtering.

The reservoir module 500 may further include a filter tube 540 and an outlet tube. 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. An outlet tube is inserted into the case 510 from the outlet 513 and extends to an upper section of the reservoir space above the liquid stored in the reservoir space to direct filtered oxygen 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 flows 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 designated space under the guidance of the gas outlet pipe, thereby playing the role of adjusting the oxygen content in the space.

In an optional 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 region and an air non-filtering region with blocked air paths. Wherein the gas filtering area is used for allowing the gas flowing into the gas inlet 512 to flow therethrough to realize filtering. The non-filtered gas region is used for receiving liquid from the outside.

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

By adopting the structure, the air resistance mechanism 530 is arranged in the liquid storage space, and the air resistance mechanism 530 is utilized to divide the liquid storage space into the air filtering area with the blocked air passage and the non-air filtering area, so that the function of purifying air only in the air filtering area can be realized. Since the air filtering area is only a sub-space of the liquid storage space and is blocked from air paths 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 cannot freely diffuse to the non-air filtering area to cause rapid discharge, so the liquid storage module 500 of the embodiment has a high purge gas release rate.

In some alternative embodiments, the case 510 further has a third sidewall and a fourth sidewall connected between the first sidewall and the second sidewall and disposed opposite to each other in the horizontal direction. A fixing member 517 is connected to an outer surface of the third sidewall and/or the fourth sidewall, and the fixing member 517 has a screw hole for cooperating with a screw to fix the case 510 to the mounting groove.

In the above embodiment, the storage compartment 122 may be a refrigerating compartment for refrigerating the articles. In one example, another storage compartment 132 is defined within the enclosure 100, such as a temperature-changing compartment or a freezing compartment, but could be a cryogenic compartment. The refrigerating and freezing device 10 further comprises an oxygen delivery pipeline embedded in the foaming layer, the oxygen delivery pipeline is communicated with the air outlet 513 and the other storage compartment 132 to deliver oxygen to the other storage compartment 132, so that a high-oxygen fresh-keeping atmosphere is created, and the fresh-keeping performance of the refrigerating and freezing device 10 is improved.

In some further examples, a one-way valve may be disposed on the oxygen delivery line for allowing one-way passage of oxygen to the other storage compartment 132 to ensure one-way flow of gas through the oxygen delivery line.
