A refrigerating and freezing apparatus 10 according to an embodiment of the present invention will be described with reference to fig. 1 to 12.

Thus, features defined as "first", "second", etc. may explicitly or implicitly include at least one of the feature, i.e. one or more of the features.

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.

Fig. 1 is a schematic configuration diagram of a refrigerating and freezing apparatus 10 according to an embodiment of the present invention. Fig. 2 is a schematic block diagram of another perspective view of the refrigeration and freezing apparatus 10 shown in fig. 1, and a part of the box 100 is hidden in fig. 2 for the convenience of illustrating the internal structure. The refrigerating and freezing device 10 according to the embodiment of the present invention may be a refrigerator, or may be a refrigerating apparatus having a low-temperature storage function, such as a freezer, or a refrigerator.

The refrigeration freezer 10 of the present embodiment may generally include a cabinet 100 and a multi-vent air conditioning circuit 410.

The cabinet 100 has a foam layer 180. The interior of the cabinet 100 defines at least one modified atmosphere space 122 for storage and at least one assembly space for assembling modified atmosphere components. The cabinet 100 may further include an inner container 120, and the interior of the inner container 120 defines the modified atmosphere space 122. The foaming layer 180 is formed outside the inner container 120.

The gas-conditioning means is a means for conditioning the gas composition of the conditioned space 122. In one example, the modified atmosphere component is an oxygen processing device 300 that consumes oxygen from the modified atmosphere space 122 via an electrochemical reaction to create a low oxygen atmosphere in the modified atmosphere space 122. In another example, the oxygen processing device 300 generates oxygen through an electrochemical reaction to create a high oxygen atmosphere in the modified atmosphere space 122. The number of the assembling spaces is one or more, correspondingly, the number of the air-conditioning components can also be one or more, and the number of the air-conditioning components is the same as the number of the assembling spaces, for example, two, three, four or five respectively, but is not limited thereto.

The multi-ported modified atmosphere conduit 410 is pre-embedded in the foam layer 180 and has at least one first conduit 411 extending towards the assembly space and at least one second conduit 412 extending towards the modified atmosphere space 122. Fig. 3 is a schematic configuration diagram of the multi-vent line 410 of the refrigeration and freezing apparatus 10 shown in fig. 2. Fig. 4 is a schematic perspective view of the multi-vent line 410 of the refrigeration freezer 10 of fig. 3. The first tube segments 411 are in one-to-one correspondence with the modified atmosphere space 122 and the second tube segments 412 are in one-to-one correspondence with the assembly space, such that the modified atmosphere space 122 is in airflow communication with the assembly space.

The number of the first tube segments 411 is one or more and the number of the first tube segments 411 is the same as the number of the modified atmosphere space 122. The number of the second pipe segments 412 is one or more, and the number of the second pipe segments 412 is the same as the number of the fitting spaces.

By adopting the scheme, the multi-way air-conditioning pipeline 410 is pre-embedded in the foaming layer 180, so that the multi-way air-conditioning pipeline 410 pre-embedded in the refrigerating and freezing device 10 is communicated with the air-conditioning space 122 and at least one assembling space for assembling air-conditioning components, when the assembling spaces are multiple, the air-conditioning components can be selectively arranged in any assembling space, the air-conditioning components arranged in any assembling space can be communicated with the air-conditioning space 122 in an air flow manner to adjust the atmosphere of the air-conditioning space 122, and thus the requirements of various design scenes of the refrigerating and freezing device 10 can be met.

It is emphasized that when there are multiple assembly spaces, different air conditioning components can be disposed in different assembly spaces based on the above-described structure of the refrigeration and freezing apparatus 10, each air conditioning component can be configured to condition one gas component of the air conditioning space 122, and the air conditioning space 122 of the refrigeration and freezing apparatus 10 can flexibly switch the fresh-keeping atmosphere because the multi-vent air conditioning pipeline 410 can communicate the air conditioning space 122 with any one of the assembly spaces.

In addition, when there are a plurality of modified atmosphere spaces 122, each modified atmosphere space 122 can be communicated with the assembly space by the multi-vent modified atmosphere pipeline 410 based on the above structure of the refrigeration and freezing apparatus 10, and the modified atmosphere can be created by the same modified atmosphere component in the plurality of modified atmosphere spaces 122 in the refrigeration and freezing apparatus 10.

In some alternative embodiments, the fitting space and the second pipe section 412 are respectively plural. The refrigeration and freezing apparatus 10 may further include an air passage adjusting mechanism 470 disposed on the multi-air-conditioning duct 410 and controlled to be movable to open and close each of the second duct sections 412 so as to selectively communicate the air-conditioning space 122 with an assembly space. Under the action of the air path adjusting mechanism 470, the controlled atmosphere space 122 can only communicate with the assembly space corresponding to one first pipe section 411 through the first pipe section 411, and the other first pipe section 411 is in a closed state. The gas path adjustment mechanism 470 is disposed on the multi-vent line 410, which may refer to being disposed on an end of the multi-vent line 410 or any section of the multi-vent line 410.

Since the controlled atmosphere component can be switchably disposed in any assembly space, and the controlled atmosphere preservation space 122 can be selectively communicated with any assembly space, by adopting the scheme of the embodiment, a plurality of assembly spaces can be mutually backed up, and when the controlled atmosphere component or the multi-controlled atmosphere pipeline 410 fails, the adjustment air passage can be rapidly switched, so that the controlled atmosphere preservation space 122 can continuously maintain a good atmosphere.

In some further embodiments, the fitting space and the second pipe section 412 are two each. And the air path adjusting mechanism 470 is a rotating member such as a damper, but not limited thereto. The air path adjusting mechanism 470 is disposed at the intersection of the two first pipe segments 411, and is controlled to be rotatably disposed to extend into or retract out of each first pipe segment 411, so as to open or close each first pipe segment 411.

In one example, when the airway adjustment mechanism 470 extends into a first tube segment 411, it shuts off the first tube segment 411; while the gas path adjusting mechanism 470 extends into one first pipe segment 411, the gas path adjusting mechanism 470 retracts out of the other first pipe segment 411, thereby opening up the other first pipe segment 411.

The rotating part is adopted as the air path adjusting mechanism 470 to control the on-off of each first pipe section 411, and the air path adjusting mechanism has the advantages of simple structure and simplicity and convenience in regulation. The control of the rotating part can be realized by a motor.

In some alternative embodiments, a mounting recess 182 is formed in the foam layer 180, which defines a mounting space. And the interior of the casing 100 defines a compressor chamber 110 for mounting a compressor, which defines another assembly space.

That is, the fitting spaces are defined by the fitting groove 182 formed in the foaming layer 180 and the compressor compartment 110 formed in the case 100, respectively. The air conditioning part is installed in the foaming layer 180 or the compressor chamber 110, and the multi-air conditioning pipeline 410 is used for opening the air path barrier between the air conditioning space 122 and the assembly space, so that the air conditioning path for communicating the air conditioning space 122 and the assembly space is creatively opened up in the embodiment, and the air composition of the air conditioning space 122 is adjusted by the air conditioning part under the condition that the volume ratio of the refrigerating and freezing device 10 is not influenced.

With the above arrangement, when the atmosphere control member is the oxygen treatment device 300, the oxygen treatment device 300 can be selectively disposed in the fitting recess 182 or the compressor room 110. When the ultra-thin box 100 is used as the refrigerating and freezing device 10, the space of the assembly groove 182 in the foaming layer 180 is narrow, and at this time, if the oxygen treatment device 300 cannot be arranged in the assembly groove 182, the oxygen treatment device 300 can be arranged in the compressor chamber 110; if the space in the compressor room 110 of the refrigerating and freezing apparatus 10 is narrow and the oxygen treatment device 300 cannot be arranged in the compressor room 110 at this time, the oxygen treatment device 300 may be disposed in the mounting recess 182 of the foam layer 180. Of course, in one example, one oxygen treatment device 300 may be disposed in each of the mounting recess 182 and the compressor chamber 110, and at this time, the two oxygen treatment devices 300 may be backup to each other, and when one of the oxygen treatment devices 300 fails, the backup oxygen treatment device 300 may be rapidly switched to maintain the fresh-keeping atmosphere of the modified atmosphere space 122.

In some alternative embodiments, the cabinet 100 has an inner container 120 defining a modified atmosphere space 122 therein. A wall of the fitting groove 182 and a wall of the compressor chamber 110 are respectively provided with a first port into which the first pipe segment 411 is inserted to realize connection. The wall of the inner container 120 is provided with a second interface for inserting the second pipe section 412 therein to realize connection.

That is, the first pipe segment 411 communicates with the fitting space by being inserted into the first port. When the fitting space and the first pipe section 411 are two, one of the first pipe sections 411 may be inserted into the first port of the fitting groove 182, and the first pipe section 411 penetrates the wall of the fitting groove 182 to communicate with the inner space of the fitting groove 182; another first pipe section 411 may be inserted into the first port of the compressor compartment 110, and the first pipe section 411 may penetrate through the wall of the compressor compartment 110 to communicate with the inner space of the compressor compartment 110. The second tube section 412 communicates with the modified atmosphere space 122 by inserting a second port. In this embodiment, there is one controlled atmosphere space 122 and one second tube section 412. The second tube section 412 may extend through the wall of the inner container 120 to communicate with the modified atmosphere space 122.

By adopting the above scheme, when the first pipe section 411 is communicated with the assembly space and the second pipe section 412 is communicated with the modified atmosphere space 122, the first pipe section 411 and the second pipe section 412 can be fixed in position, and the blockage of the air passage between the modified atmosphere space 122 and the assembly space due to the impact force in the foaming process can be reduced or avoided.

In some alternative embodiments, the multi-pass modified atmosphere line 410 may further include a main tube segment 413. A first pipe segment 411 extends from a first end of main pipe segment 413 to an assembly space and is inserted into the first port. The two first pipe segments 411 may respectively extend from the first ends of the main pipe segments 413 to the corresponding assembly spaces, and the two first pipe segments 411 may respectively extend from the first ends of the main pipe segments 413 toward different directions to communicate with the corresponding assembly spaces. The second tube section 412 extends from the second end of the main tube section 413 to the modified atmosphere space 122 and is inserted into the second port. When there are a plurality of the modified atmosphere spaces 122 and the plurality of second tube segments 412, the plurality of second tube segments 412 may extend from the second end of the main tube segment 413 to the corresponding modified atmosphere space 122, respectively, to communicate with the corresponding modified atmosphere space 122.

By connecting the first pipe segment 411 and the second pipe segment 412 by the main pipe segment 413, a plurality of first pipe segments 411 may extend at a first end of the main pipe segment 413 and/or a plurality of second pipe segments 412 may extend at a second end of the main pipe segment 413 to meet the pre-burying requirements of the multichannel pipeline.

In some alternative embodiments, the outer surface of the first tube section 411 defines an annular flange 414 extending radially outward to abut against the peripheral inner surface of the first interface, the annular flange 414 may be formed on the outer surface of the end section of the first tube section 411 near the fitting space; and/or

The outer surface of the second tube section 412 defines another annular flange 414 that extends radially outward to abut the peripheral inner surface of the second port. The annular flange 414 may be formed on the outer surface of the end section of the second tube segment 412 near the modified atmosphere space 122.

By providing the annular flanges 414 on the outer surfaces of the first tube section 411 and the second tube section 412, the annular flanges 414 have a limiting function, so that the amount of the end of the first tube section 411 coming out of the assembly space during the foaming process can be reduced or prevented, and the amount of the end of the second tube section 412 coming out of the modified atmosphere space 122 during the foaming process can be reduced or prevented, thereby maintaining the structural stability of the multi-vent pipeline 410 during the foaming process.

In alternative embodiments, the modified atmosphere space 122 and the second section 412 may be two each. The multi-pass gas regulating pipeline 410 further includes another rotating member disposed at the intersection of the two second pipe sections 412 and controlled to be rotatably disposed to extend into or retract out of each second pipe section 412 to open or close each second pipe section 412.

By adopting the scheme, the two air-conditioning preservation spaces 122 can be communicated with the assembly space by alternately utilizing the multi-air-conditioning pipeline 410, so that the air-conditioning components in the assembly space are alternately utilized to adjust the storage atmosphere.

In some alternative embodiments, there are two multi-vent gas conditioning circuits 410, an intake circuit 410a and a return circuit 410b. The intake and return

air lines

410a, 410b have at least one first pipe section 411 and at least one second pipe section 412, respectively.

Wherein the air inlet duct 410a communicates the air outlet of the modified atmosphere space 122 with the air inlet of the assembly space for directing the air from the modified atmosphere space 122 to the assembly space; the air return line 410b communicates between the air outlet of the assembly space and the air inlet of the conditioned space 122 for directing air flowing through the conditioned part to the conditioned space 122.

That is, the flow of gas through the inlet line 410a is opposite to the flow of gas through the return line 410b. Under the action of the multi-ventilation pipeline 410, the air in the atmosphere-modified fresh-keeping space 122 flows into the assembly space through the air inlet pipeline 410a and is converted into air with fresh-keeping function under the action of the atmosphere-modified part, and the air is guided to the atmosphere-modified fresh-keeping space 122 through the air return pipeline 410b to realize air flow circulation.

Two first ports may be formed on the wall of the mounting recess 182, wherein the first pipe section 411 of the air inlet pipe 410a may be inserted into one first port of the mounting recess 182, and the first port serves as an air inlet of the mounting recess 182. The first pipe segment 411 of the air return line 410b may be inserted into another first port of the fitting groove 182, which serves as an air outlet of the fitting groove 182. Two first ports may be opened on the wall of the compressor chamber 110, wherein the first pipe section 411 of the air intake duct 410a may be inserted into one first port of the compressor chamber 110, and the first port serves as an air inlet of the compressor chamber 110. The first pipe section 411 of the air return pipe 410b may be inserted into another first port of the compressor room 110, which serves as an air outlet of the compressor room 110.

The modified atmosphere space 122 is defined by the inner container 120, and two second ports may be opened on the wall of the inner container 120, wherein the second pipe section 412 of the air inlet pipeline 410a may be inserted into one second port of the inner container 120, and the second port serves as an air outlet of the modified atmosphere space 122. The second tube section 412 of the return air line 410b can be inserted into another second port of the inner container 120, which second port serves as an air inlet of the modified atmosphere space 122.

In some alternative embodiments, the refrigeration and freezing apparatus 10 may further include a connecting pipe 480 and a storage container 600, which are respectively disposed in the modified atmosphere space 122. The inside of the storage container 600 defines a storage space. The number of the connection pipes 480 is two, one of which communicates with the second pipe section 412 of the air inlet pipe 410a and is inserted into the storage container 600 to communicate the inner space of the storage container 600 with the air inlet pipe 410a, and the other of which 480 communicates with the second pipe section 412 of the air return pipe 410b and is inserted into the storage container 600 to communicate the inner space of the storage container 600 with the air return pipe 410b. When the modified atmosphere component is the oxygen processing device 300, based on the solution of the present embodiment, a low-oxygen fresh-keeping atmosphere can be created in the inner space of the storage container 600.

Fig. 5 is a schematic structural view of a foaming layer 180 of the refrigerating and freezing device 10 according to an embodiment of the present invention, which illustrates a part of the foaming layer, for example, a foaming layer at the back. When the oxygen treatment device 300 is disposed in the mounting groove 182 of the foam layer 180, the mounting groove 182 may be disposed at any position of the foam layer 180, for example, at the back of the inner container 120, or at the top, bottom, and side of the inner container 120. For a french refrigerator or a T-type refrigerator, in one example, the fitting groove 182 may be provided in a gap between the upper and

lower liners

120 and 120.

In some alternative embodiments, a side of the foam layer 180 opposite to the inner container 120 is opened with an assembling recess 182 communicating with the external environment of the foam layer 180 for assembling the oxygen treatment device 300.

After the foaming layer 180 is molded, the oxygen treatment device 300 may be fitted into the fitting groove 182 so as to be disposed in the foaming layer 180. The fitting groove 182 may be reserved during the molding of the foaming layer 180. The fitting groove 182 is recessed toward the inner container 120 in the thickness direction of the foam layer 180, and forms a gap with the inner container 120. In other words, the fitting groove 182 does not penetrate the foaming layer 180, so that the oxygen treatment device 300 fitted to the fitting groove 182 does not cling to the inner container 120. That is, a heat insulating material having a certain thickness is formed between the inner container 120 and the oxygen treatment device 300.

With the above structure, the assembling groove 182 communicating with the external environment of the foaming layer 180 is formed on the side of the foaming layer 180 opposite to the inner container 120, and a gap is formed between the assembling groove 182 and the inner container 120, so that the oxygen treatment device 300 can be mounted to the assembling groove 182 after the foaming layer 180 is molded, which is beneficial to simplifying the difficulty in assembling and disassembling the oxygen treatment device 300. In addition, since the oxygen processing device 300 is not tightly attached to the inner container 120, the embodiment of the present invention can reduce or avoid the influence of the low temperature environment of the refrigeration and freezing device 10 on the normal proceeding of the electrochemical reaction.

The oxygen treatment device 300 may be secured within the mounting recess 182 by any means including, but not limited to, screwing, snapping, riveting, welding, and bonding.

In some alternative embodiments, the cabinet 100 further includes a housing 170 covering the exterior of the foam layer 180 to sandwich the foam layer 180 with the inner container 120. The cabinet 170 has a back plate, and the fitting groove 182 is formed between the back wall of the inner container 120 and the back plate of the cabinet 170. That is, the oxygen treatment device 300 of the present embodiment is disposed in the foaming layer 180 on the back of the inner container 120. The back plate of the cabinet 170 may close the opening of the fitting recess 182 to make the appearance beautiful.

In one example, the back plate of the housing 170 may be opened with a mounting opening facing the mounting recess 182, and during the assembly process, the oxygen treatment device 300 may be directly fixed in the mounting recess 182 through the mounting opening without detaching the back plate of the housing 170. In a further example, the mounting opening may be provided with a cover plate for covering the mounting opening to provide an aesthetic appearance. In another example, the oxygen treatment device 300 may be first secured in the mounting recess 182 and then the back plate of the cabinet 170 may be covered on the back of the foam layer 180.

With the above structure, the oxygen treatment device 300 does not need to be pre-installed in the foaming layer 180, thereby avoiding adverse effects on the structure and performance of the oxygen treatment device 300 caused by the foaming process, and the assembly process of the oxygen treatment device 300 can be performed on the back of the refrigeration and freezing device 10, and the oxygen treatment device has the advantages of simple assembly process and the like.

When the oxygen treatment device 300 is disposed at the compressor room 110, for example, a bottom of the compressor room 110 is provided with a support plate for fixing the compressor, and the oxygen treatment device 300 may be directly or indirectly disposed on the support plate. 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 alternative embodiments, the atmosphere modifying component is an oxygen treatment device 300 disposed in the assembly space and including a housing 320, a cathode plate 330, and an anode plate 340. When the installation space is plural, the oxygen treatment device 300 may be selectively provided in any one of the installation spaces. Of course, when there are a plurality of assembly spaces, one oxygen treatment device 300 may be provided in each assembly space.

Fig. 6 is a schematic configuration diagram of an oxygen processing apparatus 300 of the refrigerating and freezing apparatus 10 according to an embodiment of the present invention. Fig. 7 is a schematic exploded view of the oxygen treatment device 300 of the refrigeration and freezing apparatus 10 shown in fig. 6. The housing 320 has a lateral opening 321. 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.

The cathode plate 330 is disposed at the lateral opening 321 to define an electrochemical reaction chamber for containing electrolyte together with the housing 320, and is used for consuming oxygen in the gas delivered from the modified atmosphere space to the assembly space through electrochemical reaction. 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 ^- Can be arranged inOxidation reaction occurs 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 develop the structure of the oxygen treatment device 300 suitable for other types of electrochemical reactions, and such changes and developments shall fall within the protection scope of the present invention.

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, so as to define an airflow space communicating with the cathode plate 330 together with the casing 320. The gas from the modified atmosphere space 122 flows into the gas flow space and contacts the cathode plate 330 under the guidance of the gas inlet line 410a, so that oxygen-depleted gas is formed under the action of the cathode plate 330 and is delivered back to the modified atmosphere space through the gas return line 410b, so that the modified atmosphere space creates a low-oxygen atmosphere.

The housing may be provided with a first transfer port and a second transfer port, which are respectively communicated with the air inlet pipeline 410a and the air return pipeline 410b.

The lateral opening 321 may be plural, and accordingly, the cathode plate 330 and the anode plate 340 are plural respectively. One cathode plate 330 is disposed at each lateral opening 321, thereby forming a plurality of electrochemical reaction chambers. Each electrochemical reaction chamber is provided with a cathode plate 330 and an anode plate 340, respectively, thereby forming an oxygen removing unit. A plurality of oxygen scavenging units can be connected in series or in parallel.

In some optional embodiments, the casing 320 is opened with a fluid infusion port 322 communicating with the electrochemical reaction chamber. The refrigerating and freezing device 10 further comprises a liquid storage module 500 which is arranged in the box body 100 and is provided with a box body 510, a liquid storage space for storing liquid is defined inside the box body 510, and the liquid storage space is communicated with the liquid supplementing port 322 so as to supplement electrolyte to the electrochemical reaction chamber. 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. Fig. 8 is a schematic configuration diagram of a refrigerating and freezing apparatus according to an embodiment of the present invention, and fig. 9 is a schematic internal configuration diagram of the refrigerating and freezing apparatus shown in fig. 8, illustrating a connection relationship between an oxygen treatment apparatus 300 and a liquid storage module 500.

The case 510 may have a substantially flat rectangular parallelepiped shape. The bottom wall of the box 510 is provided with a liquid outlet 511 communicated with the liquid storage space. The liquid outlet 511 is communicated with the liquid supplementing port 322 to supplement the electrolyte to the electrochemical reaction chamber.

The box 510 is provided with an air inlet 512 and an air outlet 513. The air inlet 512 and the air outlet 513 may be opened on the top wall of the case 510. The gas inlet 512 is connected to the gas outlet 323 to allow oxygen gas discharged from the gas outlet 323 to pass through the liquid storage space to filter out soluble impurities, such as electrolyte carried by the oxygen gas.

In one example, the refrigerated freezer 10 further includes another inner container 150, the inside of which defines another storage space 152, such as a temperature-changing compartment or a freezing compartment. The refrigerating and freezing device 10 further has an oxygen pipeline 440 pre-embedded in the foaming layer 180, which communicates the air outlet 513 with the other storage space 152 to deliver oxygen to the other storage space 152, creating a high-oxygen fresh-keeping atmosphere, and improving the fresh-keeping performance of the refrigerating and freezing device 10.

With the above structure, the oxygen pipeline 440 can supply clean oxygen to the storage space. In some further examples, the oxygen delivery line 440 may be provided with a one-way valve for allowing one-way passage of oxygen to the other storage space 152, thereby ensuring one-way flow of gas through the oxygen delivery line 440.

In one example, cartridge 510 is disposed within foam layer 180. The box body 510 of the liquid storage module 500 is arranged in the foaming layer 180, and the liquid storage space of the box body 510 is communicated with the liquid path of the oxygen processing device 300, so that the liquid stored in the box body 510 is used for supplying electrolyte to the oxygen processing device 300, and the box body 510 does not occupy the storage space, so that the refrigerating and freezing device 10 can supply electrolyte to the oxygen processing device 300 by using the liquid storage module 500 under the condition that the volume ratio is not influenced, and the oxygen content of the storage space can be continuously adjusted by the oxygen processing device 300.

The case 510 of the reservoir module 500 may be disposed on any portion of the foam layer 180, for example, may be disposed on the side of the inner container 150, or may be disposed on the top, bottom, and back of the inner container 150. For a french or T-type refrigerator, in one example, the cartridge 510 of the reservoir module 500 may be disposed in a gap between the upper and

lower liners

150, 150.

In some alternative embodiments, the enclosure 100 also has a housing 170, and a foam layer 180 is formed between the housing 170 and the inner container. The case 170 covers the outer side of the foaming layer 180 to clamp the foaming layer 180 with the inner container. In one example, a refrigeration and freezing apparatus may include a refrigeration liner, a temperature-changing liner, and a freezing liner. In a further example, the box 510 may be disposed within the foam layer 180 outside of the refrigeration liner.

Fig. 10 is a schematic configuration diagram of the inner container 120 of the refrigerating and freezing apparatus 10 according to an embodiment of the present invention. The inner container 120 is opened with an open interactive window 124, and the foaming layer 180 has a mounting groove communicated with the interactive window 124 for mounting the liquid storage module 500. After the foam layer 180 is molded, the reservoir module 500 may be fitted into the mounting groove so as to be disposed within the foam layer 180. The mounting groove may be reserved during the molding of the foaming layer 180. The mounting recess is recessed in a direction away from the interactive window 124 in a thickness direction of the foam layer 180 and forms a gap with the cabinet. In other words, the mounting recess does not extend through the foam layer 180, which prevents the reservoir module 500 mounted to the mounting recess from being secured to the housing. That is, a heat insulating material having a certain thickness is formed between the cabinet case and the oxygen treatment device 300.

By adopting the structure, the liquid storage module 500 does not need to be pre-installed in the foaming layer 180, the adverse effects of the foaming process on the structure and the performance of the liquid storage module 500 are avoided, the assembling process of the liquid storage module 500 can be executed in the air-conditioned fresh-keeping space 122, and the air-conditioned fresh-keeping method has the advantages of simple assembling process and the like.

By arranging the interactive window 124 on the inner container 120, arranging the mounting groove communicated with the interactive window 124 in the foaming layer 180 and forming a gap between the mounting groove and the box shell, the liquid storage module 500 can be mounted to the mounting groove after the foaming layer 180 is molded, which is beneficial to simplifying the difficulty in mounting and dismounting the liquid storage module 500. Moreover, since the mounting groove does not penetrate through the foaming layer 180, the solution of the embodiment can reduce or avoid the obvious decrease 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 180.

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.

Fig. 11 is a schematic configuration diagram of the liquid storage module 500 of the refrigeration and freezing apparatus 10 shown in fig. 9. Fig. 12 is a schematic perspective view of the reservoir module 500 of the refrigerated refrigeration unit 10 shown in fig. 11. 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. For example, the pour opening 514 is disposed on the sidewall of the box 510 facing the modified atmosphere space 122 to be exposed through the interactive window 124.

By opening the interactive window 124 on the inner container 150 and communicating the liquid injection port 514 of the box 510 with the controlled atmosphere preservation space 122 through the interactive window 124, the interactive window 124 can be used as an operation window for a user to replenish liquid into the liquid 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 fluid infusion mode of stock solution module 500 can be simplified to the above-mentioned scheme of this embodiment, makes stock solution module 500 sustainably supply electrolyte to oxygen treatment device 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 pour opening 514, the pour opening 514 is allowed to be exposed. By providing the lid 550 on the case 510 and opening or closing the liquid filling port 514 with the lid 550, the liquid filling port 514 can be 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 lid 550 may be a push-type flip lid that is pushed to pivotally flip up to extend at least partially into the modified atmosphere space 122 through the interactive window 124 to open the pour spout 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 it is desired to open the pour opening 514, the top of the lid 550 can be pressed to disengage the top of the lid 550 from the base 510, whereupon the lid 550 can be rotated about the axis of rotation and extended at least partially into the modified atmosphere space 122 to open the pour opening 514.

The assembling structure between the push type flip cover and the box 510 should be easily known by those skilled in the art based on the understanding of the embodiments of the present disclosure, 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 viewable area 516 is also disposed on the side wall of the housing 510 facing the modified atmosphere space 122 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 interactive window 124 can expose the visible area 516, the user can observe the liquid storage amount of the liquid storage space very conveniently, 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 interactive window 124 may be located on a sidewall of the inner container 150, with the mounting recess correspondingly disposed between the sidewall of the inner container 150 and the sidewall of the cabinet.

Because the side wall of the inner container 150 is not easily blocked by the articles stored in the controlled atmosphere space 122 and is close to the movable area of the user, the interaction window 124 is arranged on the side wall of the inner container 150, and the liquid storage module 500 is embedded into the foaming layer 180 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 controlled atmosphere space 122, and the liquid supplementing operation can be timely executed when the liquid storage amount of the liquid storage module 500 is insufficient.

In some optional embodiments, the reservoir module 500 may further include a level sensor disposed in the reservoir space and configured to detect a level of the reservoir space. 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 case 510 has a first sidewall that is flush with a sidewall of the liner 150 and encloses the interaction window 124 and a second sidewall opposite the first sidewall and hidden inside the mounting recess. The pour spout 514 is located on the first side wall. The open area of the interactive window 124 and the surface area of the first sidewall of the case 510 may be substantially the same, such that the first sidewall of the case 510 just closes the interactive window 124 and the outer surface of the first sidewall is connected to the inner surface of the sidewall of the inner container 150 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 516 can also be disposed on the first sidewall, for example, can be disposed on 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 communicated 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. A liquid outlet is arranged on the bottom wall and is communicated with a liquid supplementing port 322 to supplement electrolyte to the electrochemical reaction bin.

The refrigerating and freezing device 10 further includes a liquid supplementing pipeline 420 pre-embedded in the foaming layer 180, a first end of the liquid supplementing pipeline 420 is communicated with the liquid supplementing port 322 of the oxygen processing device 300, and a second end of the liquid supplementing pipeline 420 is communicated with the liquid outlet of the liquid storage module 500, so that the liquid flowing out of the liquid storage space from the liquid outlet is guided to the liquid supplementing port 322, and the liquid is supplemented to the electrochemical reaction chamber. The liquid outlet is higher than the liquid supplementing 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 the aid of a power device.

Of course, in other examples, ports may be shifted lower than fluid infusion port 322 or even with fluid infusion port 322. At this time, a pump may be installed on the fluid infusion pipeline 420 to drive the fluid in the fluid storage space to flow into the electrochemical reaction chamber 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 420 may be provided with a check valve for allowing one-way passage of fluid from the fluid outlet, thereby ensuring one-way flow of fluid through the fluid replacement line 420.

The refrigerating and freezing device 10 further includes a filtering pipeline 430 pre-embedded in the foaming layer 180, a first end of the filtering pipeline 430 is communicated with the air outlet 323 of the oxygen processing device 300, and a second end of the filtering pipeline 430 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 gas-unfiltered area 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 resistance 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 liquid 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 blocking mechanism 530, and the unfiltered air region is located on the other lateral side of the air blocking 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 embodiments, the modified atmosphere space 122 may be a refrigerated space for refrigerated items.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
