The appearances of the phrases in various places in the specification are not necessarily all referring to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0061] The present embodiments provide a refrigeration device 10. Figure 1 is a schematic structural diagram of the refrigeration device 10 according to an embodiment of the present application. Figure 2 is a schematic internal structural diagram of the refrigeration device 10 according to an embodiment of the present application. The refrigeration device 10 can generally include a cabinet 100, a storage container 600, a gas regulation pipeline 440 and a gas regulation assembly. The refrigeration device 10 according to the present embodiments can be a refrigerator, or a freezer, or a refrigerator-freezer, or other refrigeration equipment with low-temperature storage function.

[0062] The cabinet 100 defines an internal storage compartment. For example, the cabinet 100 can include an inner liner, and the inner side of the inner liner can define the above-mentioned storage compartment.

[0063] The storage container 600 is arranged in the storage compartment, and the interior of the storage container 600 defines a storage space. The wall of the storage container 600 is provided with a gas passage 610 communicating with the storage space. For example, the gas passage 610 can be an opening or a hole provided on the wall of the storage container 600. The storage container 600 can be provided as one or more, for example, two.

[0064] The gas regulation pipeline 440 communicates with the gas passage 610 and is used to transport gas, so that the storage space exchanges gas with the external environment thereof. The external environment of the storage space can refer to other spaces inside the cabinet 100 and outside the storage space, such as a supply air duct between the air duct cover plate and the rear wall of the inner liner, a foaming layer, or a press machine warehouse; when the storage space is the internal space of the storage container 600 arranged in the storage compartment, the external environment of the storage space can refer to the internal space of the storage compartment formed outside the storage container 600. In other examples, the external environment of the storage space can also refer to the external space of the cabinet 100.

[0065] Figure 3 is Figure 2 is a schematic exploded view of the internal structure of the refrigeration device 10. Figure 4 is Figure 3The local enlarged view of the middle A. The gas path assembly includes a positioning mechanism 850 fixed outside the storage container 600, and having a fixing portion for the joint between the gas adjusting pipe 440 and the air vent 610 to be fixed thereon.

[0066] By setting the gas path assembly and using the positioning mechanism 850 of the gas path assembly to fix the joint between the gas adjusting pipe 440 and the air vent 610 of the storage container 600, loosening of the joint between the gas adjusting pipe 440 and the air vent 610 can be reduced or avoided, which is conducive to improving the stability of the gas path connection between the gas adjusting pipe 440 and the air vent 610 of the storage container 600 and reducing or avoiding gas leakage due to loosening of the joint.

[0067] The joint between the gas adjusting pipe 440 and the air vent 610 of the storage container 600 can be achieved in any suitable manner to achieve gas path communication. In one example, the gas adjusting pipe 440 can be directly connected to the air vent 610, and in this case, the end section of the gas adjusting pipe 440 connected to the air vent 610 serves as the joint between the gas adjusting pipe 440 and the air vent 610. In another example, a connecting structure can be provided between the gas adjusting pipe 440 and the air vent 610, so that the gas adjusting pipe 440 is indirectly connected to the air vent 610, and in this case, the connecting structure between the gas adjusting pipe 440 and the air vent 610 can serve as the joint between the gas adjusting pipe 440 and the air vent 610.

[0068] By using the positioning mechanism 850 to fix the joint between the gas adjusting pipe 440 and the air vent 610, even if the storage container 600 deviates from the original position or shakes during the user's taking and placing of the items, the gas adjusting pipe 440 will not be moved, and when the storage container 600 is returned to the original position, the gas path connection between the gas adjusting pipe 440 and the air vent 610 can be re-established. Therefore, based on the scheme of the present embodiment, the storage container 600 does not need to be fixedly arranged in the storage compartment, and the gas path connection between the gas adjusting pipe 440 and the air vent 610 does not restrict the movement of the storage container 600, which improves the use convenience of the storage container 600.

[0069] In some optional embodiments, the gas path assembly further includes a tubular connecting piece 820, a first end of which communicates with the air vent 610 and a second end of which communicates with the gas adjusting pipe 440 and serves as the joint between the gas adjusting pipe 440 and the air vent 610. The fixing portion defines a hollow cylindrical channel for the tubular connecting piece 820 to be inserted therein to achieve fixed assembly.

[0070] By arranging the tubular connecting member 820 and connecting one end of the tubular connecting member 820 to the air vent 610 and the other end to the modified atmosphere gas pipeline 440, the modified atmosphere gas pipeline 440 and the air vent 610 are connected by the tubular connecting member 820 as the joint between the modified atmosphere gas pipeline 440 and the air vent 610, and the port of the modified atmosphere gas pipeline 440 and the air vent 610 do not need to be directly and sealingly connected, which is conducive to simplifying the connection between the storage space of the refrigeration and freezing device 10 and the modified atmosphere gas pipeline 440.

[0071] In some optional embodiments, the positioning mechanism 850 includes a body part 851 and a cover part 852. The body part 851 is fixed in the storage compartment and defines a downwardly recessed and arc-shaped lower recessed arc plate as a lower passage wall of the hollow cylindrical passage.

[0072] The cover part 852 defines an upwardly recessed and arc-shaped upper recessed arc plate as an upper passage wall of the hollow cylindrical passage. The upper passage wall and the lower passage wall jointly form a fixing part.

[0073] The body part 851 and the cover part 852 can be separately arranged and not integrally formed. The body part 851 and the cover part 852 jointly define the hollow cylindrical passage for arranging the tubular connecting member 820. Since the body part 851 and the cover part 852 can be separately arranged, the tubular connecting member 820 can be first placed on the lower recessed arc plate of the body part 851 and then the cover part 852 is fixed on the body part 851 when the tubular connecting member 820 is assembled, so that the tubular connecting member 820 is stably assembled in the hollow cylindrical passage. When the tubular connecting member 820 needs to be disassembled, the body part 851 and the cover part 852 can be separated, and the disassembly process is simple.

[0074] The cover part 852 is detachably assembled above the body part 851. The cover part 852 further defines first threaded holes located on both sides of the upper passage wall. The body part 851 is correspondingly formed with second threaded holes located on both sides of the lower passage wall and corresponding to the first threaded holes, so as to be detachably assembled by screwing.

[0075] In one example, the air vent 610 is located on the back wall of the storage container 600. For example, the body part 851 can be arranged in abutment with the back wall of the storage container 600.

[0076] The positioning mechanism 850 further includes a bent part 854 bent forward or backward from an end of the body part 851 and arranged in abutment with the side wall of the storage compartment. The bent part 854 is provided with third threaded holes for fixedly assembling the bent part 854 to the side wall of the storage compartment by screwing.

[0077] When the vent 610 is formed on the back wall of the storage container 600, the body part 851 is fixed to the back side of the storage container 600, and the end part of the body part 851 is connected to the forwardly bent bending part 854, since the bending part 851 can be fixedly connected to the side wall of the storage compartment by screwing, based on the above structure, on the one hand, the positioning mechanism 850 of the gas circuit assembly can be stably assembled in the storage compartment to fix the joint between the gas modulation pipe 440 and the vent 610, and on the other hand, the body part 851 can be fixed at any position away from the back wall of the storage compartment, so that enough space is reserved between the body part 851 and the back wall of the storage compartment to arrange the pipe.

[0078] The vent 610 is hollow cylindrical, and it protrudes outward from the wall of the storage container 600 and at least partially extends into the hollow cylindrical passage. The first end 821 of the tubular connecting piece 820 defines a hollow cylindrical interface for the vent 610 to nest in.

[0079] When the vent 610 is hollow cylindrical and at least partially extends into the hollow cylindrical passage and nests in the hollow cylindrical passage defined by the first end 821 of the tubular connecting piece 820, moving the storage container 600 away from the tubular connecting piece 820 can make the vent 610 come out of the hollow cylindrical passage defined by the first end 821 of the tubular connecting piece 820, and moving the storage container 600 towards the tubular connecting piece 820 can make the vent 610 nest in the hollow cylindrical passage defined by the first end 821 of the tubular connecting piece 820 again, therefore, based on the above structure, the gas circuit connection between the storage container 600 and the gas modulation pipe 440 can be realized in a detachable manner.

[0080] In some optional embodiments, the gas circuit assembly further comprises a gas circuit adapter 810. Figure 5 is Figure 3 A schematic structural diagram of the gas circuit adapter 810 of the refrigeration and freezing device 10 shown. Figure 6 is Figure 5 A schematic perspective view of the gas circuit adapter 810 of the refrigeration and freezing device 10 shown.

[0081] The gas circuit adapter 810 has a first interface 811 connected to the gas modulation pipe 440 and a second interface 812 connected to the second end of the tubular connecting piece 820, and a gas flow passage 813 is connected between the second interface 812 and the first interface 811, so that the gas modulation pipe 440 indirectly communicates with the vent 610. The gas flow passage 813 is arranged obliquely relative to the horizontal plane.

[0082] The temperature of the storage space is generally low. Since the air path adapter 810 is directly connected to the air vent 610 of the storage container 600 via the tubular connecting piece 820 and is close to the storage space, when the temperature of the storage space is low, the temperature of the air path adapter 810 is also correspondingly low.

[0083] By inclining the air flow channel 813 of the air path adapter 810 relative to the horizontal plane, the included angle between the air flow channel 813 and the horizontal plane can form an acute angle or a right angle. When the gas flowing through the air path adapter 810 contains moisture and the temperature of the storage space is low, the moisture carried by the gas is not easy to stay inside the air flow channel 813, which is beneficial to reduce or avoid the air flow channel 813 being blocked due to frost, so that the sustainable gas exchange between the storage space and the external environment of the storage space can be realized, and the storage space can maintain a low-temperature fresh-keeping atmosphere for a long time.

[0084] The first interface 811 and the second interface 812 are hollow cylindrical interfaces respectively protruding outward from the outer surface of the air path adapter 810.

[0085] The inner part of the first interface 811 and the second interface 812 respectively defines a hollow channel that communicates with the air flow channel 813 and is inclined relative to the horizontal plane. That is, the hollow channel of the first interface 811 and the hollow channel of the second interface 812 are also respectively inclined.

[0086] With the above structure, since the hollow channel of each interface communicates with the air flow channel 813, it is equivalent to extending the path of the inclined section of the air path adapter 810, which can further reduce the risk of air path blockage of the air path adapter 810, and keep the air regulating pipeline 440 and the air vent 610 in unobstructed connection.

[0087] In one example, the second end 822 of the tubular connecting piece 820 defines a hollow cylindrical interface for the second interface 812 to be nested therein, and the end of the air regulating pipeline 440 communicating with the air vent 610 defines a hollow cylindrical interface for the first interface 811 to be nested therein, so that the air regulating pipeline 440 indirectly communicates with the air vent 610.

[0088] In some optional embodiments, the air flow channel 813 of the air path adapter 810 includes a first channel section 813a and a second channel section 813b. The first channel section 813a communicates with the hollow channel inside the first interface 811. The second channel section 813b communicates with the first channel section 813a and communicates with the hollow channel inside the second interface 812.

[0089] The inclination degree of the second channel section 813b is set to be different from that of the first channel section 813a. In other words, the angle between the second channel section 813b and the horizontal plane is different from the angle between the first channel section 813a and the horizontal plane, which results in different flow rates of the liquid carried by the gas when flowing through the first channel section 813a and the second channel section 813b.

[0090] By arranging two channel sections with different inclination degrees in the gas path adapter 810, on the one hand, the connection mode between each channel section and the corresponding interface can be simplified, and on the other hand, since the flow rates of the gas when flowing through the first channel section 813a and the second channel section 813b are different, the above-mentioned scheme of the present embodiment can further reduce the risk of gas path blockage of the gas flow channel 813.

[0091] In some optional embodiments, the angle between the first channel section 813a and the horizontal plane is greater than the angle between the second channel section 813b and the horizontal plane.

[0092] With the above scheme, when the gas adjusting pipeline 440 delivers gas to the storage space, even if the liquid carried by the gas may condense in the first channel section 813a and the second channel section 813b, since the liquid carried by the gas will condense first in the first channel section 813a, the flow rate of the liquid beads is large, and when these liquid beads enter the second channel section 813b, they will flush the surface of the second channel section 813b, and the liquid beads condensed in the second channel section 813b will continue to flow forward at a high speed, thereby effectively reducing the risk of gas path blockage of the gas path adapter 810.

[0093] In some optional embodiments, the first interface 811 is formed in the upper section of the gas path adapter 810, and the hollow channel inside the first interface 811 is arranged to be inclined upward away from the outer surface of the gas path adapter 810. The central axis of the first channel section 813a is coaxial with the central axis of the hollow channel inside the first interface 811. That is, the inclination degree of the hollow channel inside the first interface 811 is the same as that of the first channel section 813a.

[0094] The second interface 812 is formed in the side section of the gas path adapter 810 and is located below the second interface 812. The hollow channel inside the second interface 812 is arranged to be inclined downward away from the outer surface of the gas path adapter 810. The central axis of the second channel section 813b is coaxial with the central axis of the hollow channel inside the second interface 812. That is, the inclination degree of the hollow channel inside the second interface 812 is the same as that of the second channel section 813b.

[0095] Based on the above structure, the air adjusting pipeline 440 can be connected to the upper part of the air path adapter 810, and the tubular connecting piece can be connected to the side part of the air path adapter 810.

[0096] In one example, the port of the air adjusting pipeline 440 can be nested in the hollow channel of the first interface 811, and the tubular connecting piece can be nested in the hollow channel of the second interface 812.

[0097] In one example, the tubular connecting piece 820 is made of elastic material. Since the tubular connecting piece 820 made of elastic material can tightly fit the interface nested therein, the tubular connecting piece 820 is used to connect the second interface 812 and the air vent 610, so that the second interface 812 and the air vent 610 are airtightly connected.

[0098] In some optional embodiments, the refrigeration and freezing device 10 further comprises an oxygen treatment device 300 arranged in the cabinet 100, and the oxygen treatment device 300 has a shell 320 and an electrode pair, the inside of the shell 320 defines an electrochemical reaction chamber for containing electrolyte, and the electrode pair is arranged in the electrochemical reaction chamber and is used to transfer external oxygen to the electrochemical reaction chamber through an electrochemical reaction.

[0099] Figure 7 is a schematic structural diagram of the oxygen treatment device 300 of the refrigeration and freezing device 10 according to an embodiment of the present application. Figure 8 is Figure 7 is a schematic exploded view of the oxygen treatment device 300 of the refrigeration and freezing device 10 shown in FIG. 8.

[0100] The electrode pair can include a cathode plate 330 and an anode plate 340. The electrochemical reaction chamber is a place for the cathode plate 330 and the anode plate 340 to perform an electrochemical reaction, and can contain an alkaline electrolyte, such as 1 mol / L NaOH, and the concentration thereof can be adjusted according to actual needs.

[0101] The shell 320 has a lateral opening 321. For example, the shell 320 can have a flat cuboid shape. The lateral opening 321 can be arranged on any face of the shell 320, such as the top face, the bottom face, or the side face. In one example, the lateral opening 321 can be arranged on the face with the largest area of the shell 320.

[0102] The cathode plate 330 is arranged at the lateral opening 321 to jointly define the electrochemical reaction chamber for containing electrolyte with the shell 320, and is used to consume oxygen through an electrochemical reaction. Oxygen in the air can be reduced at the cathode plate 330, i.e.: - O2+2H2O+4e - →4OH

[0103] The anode plate 340 is disposed in the electrochemical reaction chamber in spaced relation to the cathode plate 330, and is configured to provide reactants to the cathode plate 330 by electrochemical reaction and generate oxygen. The cathode plate 330 generates OH - An oxidation reaction can occur at the anode plate 340, and oxygen is generated, i.e. 4OH - → O2+ 2H2O + 4e - .

[0104] The above examples of electrochemical reactions of the cathode plate 330 and the anode plate 340 are merely illustrative, and based on the above-described embodiments, one skilled in the art should easily change the type of electrochemical reaction, or extend to the structure of the oxygen treatment device 300 suitable for other types of electrochemical reactions, which should all fall within the protection scope of the present application.

[0105] The housing 320 is provided with an exhaust hole 323 communicating with the electrochemical reaction chamber, for discharging oxygen from the electrochemical reaction chamber. The gas regulation pipeline 440 is provided with an end (e.g. the second end of the gas regulation pipeline 440) away from the air inlet 610, which is configured to communicate with the exhaust hole 323. The second end of the gas regulation pipeline 440 can directly or indirectly communicate with the exhaust hole 323. The end of the gas regulation pipeline 440 communicating with the air inlet 610 can be the first end of the gas regulation pipeline 440, which can directly or indirectly communicate with the first interface 811 of the gas regulation adapter 810.

[0106] In some optional embodiments, the housing 320 is provided with a liquid supplementing hole 322 communicating with the electrochemical reaction chamber. The refrigeration and freezing device 10 further comprises a liquid storage module 500, which is disposed in the cabinet 100 and has a box body 510, the interior of the box body 510 defining a liquid storage space for storing liquid, the liquid storage space communicating with the liquid supplementing hole 322 to supplement electrolyte to the electrochemical reaction chamber. The liquid stored in the liquid storage space can be water, or can be electrolyte, which can have a lower concentration than the electrolyte stored in the electrochemical reaction chamber.

[0107] The box body 510 is provided with an air inlet 512 and an air outlet 513. The air inlet 512 and the air outlet 513 can be provided on the top wall of the box body 510. The air inlet 512 communicates with the exhaust hole 323 to allow oxygen discharged from the exhaust hole 323 to enter the liquid storage space to filter soluble impurities, such as electrolyte carried by the oxygen. The air outlet 513 is configured to allow filtered oxygen to be discharged outwardly, and directly communicates with the end of the gas regulation pipeline 440 away from the air inlet 610, so that the gas regulation pipeline 440 indirectly communicates with the exhaust hole 323.

[0108] With the above structure, the gas regulation pipeline 440 can deliver clean oxygen to the liquid storage space.

[0109] In one example, the refrigerator-freezer 10 can include an inner container 120 and an inner container 150. In the above example, the storage compartment can be the interior space of the inner container 150. The inner container 150 can define a temperature-variable compartment 152 or a freezing compartment 152. For the sake of distinction, the above-mentioned storage space can be named as a first storage space. The inner container 120 defines another storage compartment, for example, a refrigerating compartment, and an interior space 122 of the refrigerating compartment can be defined as another storage space, which can be named as a second storage space for the sake of distinction. The cathode plate of the oxygen treatment device 300 is in airflow communication with the storage space 122, so as to reduce the oxygen content of the storage space through an electrochemical reaction.

[0110] In another example, the oxygen treatment device 300 can be arranged in the foamed layer. Figure 9 is a schematic structural view of a refrigerator-freezer according to an embodiment of the present application, Figure 10 is Figure 9 is a schematic internal structural view of a refrigerator-freezer, and the foamed layer is hidden for the sake of showing the structure and connection relationship of various components. At this time, the refrigerator-freezer 10 can further include an air exchange pipeline 200 embedded in the foamed layer. The air exchange pipeline 200 can include an air inlet pipeline 210 and an air outlet pipeline 220.

[0111] The air inlet pipeline 210 is used to guide the gas in the storage space 122 to the cathode plate 330, and the air outlet pipeline 220 is used to guide the gas flowing through the cathode plate 330 back to the storage space 122, so as to reduce the oxygen content of the storage space 122. For example, a first air exchange opening communicating with the first end of the air inlet pipeline 210 and a second air exchange opening communicating with the first end of the air outlet pipeline 220 are formed in the container wall of the inner container 120. Each air exchange opening is an opening formed in the container wall of the inner container 120. The second end of the air inlet pipeline 210 and the second end of the air outlet pipeline 220 can respectively communicate with the two ends of the cathode plate 330. Specifically, the second end of the air inlet pipeline 210 can communicate with the upwind side of the cathode plate 330, and the second end of the air outlet pipeline 220 can communicate with the downwind side of the cathode plate 330, so that the gas flowing out of the air inlet pipeline 210 can flow into the air outlet pipeline 220 after flowing through the cathode plate 330.

[0112] With the above structure, the storage space 122 and the oxygen treatment device 300 are communicated by the air inlet pipeline 210 and the air outlet pipeline 220. The gas with a high oxygen content in the storage space 122 can flow to the cathode plate 330 through the air inlet pipeline 210, so that the cathode plate 330 uses the oxygen therein as a reactant to perform an electrochemical reaction, and forms low-oxygen gas with a low oxygen content. These low-oxygen gas can return to the storage space 122 through the air outlet pipeline 220, thereby reducing the oxygen content of the storage space 122.

[0113] The oxygen treatment device 300 can be arranged at any position of the foamed layer, 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 door refrigerator or a T-shaped refrigerator, in an example, the oxygen treatment device 300 can be arranged in the gap between the upper inner container 120 and the lower inner container 120.

[0114] In some optional embodiments, the foamed layer is provided with an assembly groove on the side opposite to the inner container 120, which is communicated with the external environment of the foamed layer for assembling the oxygen treatment device 300.

[0115] After the foamed layer is formed, the oxygen treatment device 300 can be assembled into the assembly groove, thereby being arranged in the foamed layer. The assembly groove can be reserved during the forming of the foamed layer. The assembly groove is recessed along the thickness direction of the foamed layer towards the inner container 120, and forms a gap with the inner container 120. In other words, the assembly groove does not penetrate through the foamed layer, so that the oxygen treatment device 300 assembled into the assembly groove is not tightly attached to the inner container 120. That is, the inner container 120 and the oxygen treatment device 300 are separated by a certain thickness of thermal insulation material.

[0116] With the above structure, by providing the assembly groove communicated with the external environment of the foamed layer on the side opposite to the inner container 120, and forming a gap between the assembly groove and the inner container 120, the oxygen treatment device 300 can be installed into the assembly groove after the foamed layer is formed, which is beneficial to simplify the disassembly and assembly difficulty of the oxygen treatment device 300. Since the oxygen treatment device 300 is not tightly attached to the inner container 120, the scheme of the present embodiment can reduce or avoid the influence of the low-temperature environment of the refrigeration and freezing device 10 on the normal operation of the electrochemical reaction.

[0117] The oxygen treatment device 300 can be fixed in the assembly groove, and the fixing methods include but are not limited to screwing, clamping, riveting, welding and bonding.

[0118] In some optional embodiments, the cabinet 100 further comprises a cabinet shell 170, which is arranged outside the foamed layer to sandwich the foamed layer with the inner container 120. The cabinet shell 170 has a back plate, and the assembly groove is formed between the back wall of the inner container 120 and the back plate of the cabinet shell 170. That is, the oxygen treatment device 300 of the present embodiment is arranged in the foamed layer at the back of the inner container 120. The back plate of the cabinet shell 170 can close the opening of the assembly groove to make the appearance more beautiful.

[0119] In one example, the back plate of the box shell 170 can be provided with a mounting opening opposite the assembly groove. During the assembly process, the oxygen treatment device 300 can be directly fixed into the assembly groove through the mounting opening without disassembling the back plate of the box shell 170. In a further example, a cover plate can be arranged at the mounting opening to cover the mounting opening to make the appearance more beautiful. In another example, the oxygen treatment device 300 can be first fixed into the assembly groove, and then the back plate of the box shell 170 is covered on the back of the foaming layer.

[0120] With the above structure, the oxygen treatment device 300 does not need to be preassembled in the foaming layer, avoiding the foaming process from adversely affecting the structure and performance of the oxygen treatment device 300, and the assembly process of the oxygen treatment device 300 can be performed at the back of the refrigeration and freezing device 10, having the advantages of simple assembly process, etc.

[0121] In yet another example, a compressor chamber for mounting a compressor is further defined in the box body 100. The oxygen treatment device 300 can be arranged in the compressor chamber. For example, the bottom of the compressor chamber is provided with a support plate for fixing the compressor, and the oxygen treatment device 300 can be directly or indirectly arranged on the support plate.

[0122] In one example, the box body 510 is arranged in the foaming layer. By arranging the box body 510 of the liquid storage module 500 in the foaming layer and making the liquid storage space of the box body 510 communicate with the liquid circuit of the oxygen treatment device 300, the electrolyte of the oxygen treatment device 300 can be supplemented by the liquid stored in the box body 510. Since the box body 510 does not occupy the storage space 122, the refrigeration and freezing device 10 can supplement the electrolyte of the oxygen treatment device 300 by the liquid storage module 500 without affecting the volume rate, so that the oxygen treatment device 300 can continuously adjust the oxygen content of the storage space 122.

[0123] The box body 510 of the liquid storage module 500 can be arranged at any position of the foaming layer, for example, can be arranged at the side of the inner container 150, or can be arranged at the top, bottom and back of the inner container 150. For a French type refrigerator or a T type refrigerator, in one example, the box body 510 of the liquid storage module 500 can be arranged in the gap between the upper inner container 150 and the lower inner container 150.

[0124] In some optional embodiments, the box body 100 further has a box shell, and the foaming layer is formed between the box shell and the inner container 150. The box shell is arranged outside the foaming layer to hold the foaming layer with the inner container 150. In one example, the refrigeration and freezing device can include a refrigeration inner container, a variable temperature inner container and a freezing inner container. In a further example, the box body can be arranged in the foaming layer outside the refrigeration inner container.

[0125] Figure 11This is a schematic structural diagram of the inner liner 120 of a refrigeration and freezing apparatus 10 according to an embodiment of the present invention. The inner liner 120 has an open-shaped interaction window 124, and the foam layer has a mounting groove communicating with the interaction window 124 for assembling a liquid storage module 500. After the foam layer is formed, the liquid storage module 500 can be assembled into the mounting groove, thereby being disposed within the foam layer. The mounting groove can be pre-formed during the foam layer forming process. The mounting groove is recessed along the thickness direction of the foam layer in a direction away from the interaction window 124, and forms a gap with the shell. In other words, the mounting groove does not penetrate the foam layer, so that the liquid storage module 500 assembled into the mounting groove will not be in close contact with the shell. That is, a certain thickness of heat insulation material is formed between the shell and the oxygen treatment device 300.

[0126] With the above structure, the liquid storage module 500 does not need to be pre-installed in the foaming layer, avoiding adverse effects of the foaming process on the structure and performance of the liquid storage module 500. Furthermore, the assembly process of the liquid storage module 500 can be performed within the storage space 122, which has the advantages of simple assembly process.

[0127] By creating an interactive window 124 on the inner liner 120 and providing an installation groove communicating with the interactive window 124 in the foam layer, and creating a gap between the installation groove and the shell, the liquid storage module 500 can be installed into the installation groove after the foam layer is formed. This simplifies the installation and removal of the liquid storage module 500. Furthermore, since the installation groove does not penetrate the foam layer, the solution in this embodiment can reduce or avoid a significant reduction in the insulation performance of the refrigeration and freezing device 10 due to installing the liquid storage module 500 within the foam layer.

[0128] The liquid storage module 500 can be fixed in the mounting groove, and the fixing methods include but are not limited to screwing, snap-fitting, riveting, welding and bonding.

[0129] In some alternative embodiments, the housing 510 has an injection port 514 that communicates with the liquid storage space, and the injection port 514 is exposed through the interactive window 124, thereby allowing external liquid to be injected into the liquid storage space. Figure 12 yes Figure 10 The diagram shows a schematic structural diagram of the liquid storage module of the refrigeration and freezing device. Figure 13 yes Figure 12 A schematic perspective view of the liquid storage module of the refrigeration and freezing device shown. For example, the liquid inlet 514 is provided on the side wall of the housing 510 facing the storage space 122, and is exposed through the interactive window 124.

[0130] The interactive window 124 is used as an operation window for the user to supplement the liquid in the storage space by being formed on the inner container 150 and by connecting the liquid injection port 514 of the box body 510 to the storage space 122 through the interactive window 124. Since the interactive window 124 exposes the liquid injection port 514, when the liquid in the storage space is insufficient, the external liquid can be injected into the storage space through the liquid injection port 514. Therefore, the above-mentioned solution of the present embodiment can simplify the liquid supplementing mode of the liquid storage module 500, and enable the liquid storage module 500 to continuously supplement the electrolyte to the oxygen treatment device 300.

[0131] The box body 510 is provided with a cover 550, which is reciprocally movably arranged at the liquid injection port 514 to open or close the liquid injection port 514. When the cover 550 opens the liquid injection port 514, the liquid injection port 514 is exposed. By arranging the cover 550 on the box body 510 and using the cover 550 to open or close the liquid injection port 514, the liquid injection port 514 can be in an open state only when receiving the external liquid, thereby reducing or avoiding the entry of foreign matters into the storage space and keeping the liquid stored in the storage space clean.

[0132] The cover 550 can be a press-type pop-up cover, which can be pressed to be rotatably popped up to at least partially extend into the storage space 122 through the interactive window 124, thereby opening the liquid injection port 514.

[0133] In one example, the bottom of the cover 550 can be connected to the box body 510 through a rotating shaft and pivotably connected to the box body 510. When the cover 550 closes the liquid injection port 514, the outer surface of the cover 550 is coplanar with the outer surface of the box body 510. At this time, the top of the cover 550 can be connected to the box body 510 through a clamping structure. When it is necessary to open the liquid injection port 514, the top of the cover 550 can be pressed to make the top of the cover 550 disengage from the box body 510. At this time, the cover 550 can be rotated around the rotating shaft and at least partially extend into the storage space 122, thereby opening the liquid injection port 514.

[0134] Based on the understanding of the embodiments of the present disclosure, those skilled in the art should easily know the assembly structure between the press-type pop-up cover and the box body 510, which will not be described herein again.

[0135] In some optional embodiments, at least a portion of the box body 510 is made of a transparent material to form a visible area 516 for exposing the liquid storage amount of the box body 510. The transparent material can be polymethyl methacrylate, polycarbonate, polyethylene terephthalate, or polypropylene, etc.

[0136] The visual area 516 of the present embodiment is exposed through the interactive window 124. The visual area 516 is longitudinally arranged and located below the liquid inlet 514. For example, the visual area 516 is also arranged on the side wall of the box body 510 facing the storage space 122 so as to be exposed through the interactive window 124.

[0137] By arranging the visual area 516 on the box body 510 and making the visual area 516 opposite to the interactive window 124, the interactive window 124 can be used as an observation window for the user to observe the liquid level in the storage space. Since the interactive window 124 can expose the visual area 516, the user can conveniently observe the liquid storage amount in the storage space, and therefore, the above-mentioned scheme of the present embodiment can provide the user with an intuitive interactive experience. When the liquid storage amount in the storage space is insufficient, the user can take timely liquid supplement measures.

[0138] In one example, the interactive window 124 can be located on the side wall of the inner container 150, and the mounting groove is correspondingly arranged between the side wall of the inner container 150 and the side wall of the box shell.

[0139] Since the side wall of the inner container 150 is not easily blocked by the articles stored in the storage space 122 and is close to the movable area of the user, arranging the interactive window 124 on the side wall of the inner container 150 and embedding the liquid storage module 500 in the foaming layer of the side portion of the box body 100 can reduce the interaction difficulty between the user and the liquid storage module 500 to a certain extent, and the user can quickly obtain the liquid storage amount information of the liquid storage module 500 without moving the articles stored in the storage space 122, and can timely perform liquid supplement operation when the liquid storage amount of the liquid storage module 500 is insufficient.

[0140] In some optional embodiments, the liquid storage module 500 can further include a liquid level sensor arranged in the liquid storage space and used for detecting the liquid level of the liquid storage space. When the liquid level sensor detects that the liquid level of the liquid storage space is lower than a set value, the refrigeration and freezing device 10 can send an alarm signal, for example, can send the alarm signal to the user through wireless transmission technology to remind the user to timely supplement liquid.

[0141] In some further examples, the box body 510 has a first side wall flush with the side wall of the inner container 150 and closing the interactive window 124, and a second side wall opposite to the first side wall and hidden inside the mounting groove. The liquid inlet 514 is located on the first side wall. The opening area of the interactive window 124 and the surface area of the first side wall of the box body 510 can be substantially the same, so that the first side wall of the box body 510 just closes the interactive window 124 and makes the outer surface of the first side wall and the inner surface of the side wall of the inner container 150 connect to form a complete plane, so as to make the appearance beautiful.

[0142] The liquid injection port 514 can be arranged on the upper section of the first side wall. The visible area 516 can also be arranged on the first side wall, for example, on the middle section or lower section of the first side wall.

[0143] The box body 510 can have a substantially flat cuboid shape. The box body 510 is provided with a liquid outlet 511 communicating with the liquid storage space. The box body 510 further has a top wall and a bottom wall connected between the first side wall and the second side wall and arranged opposite in the vertical direction. The bottom wall is provided with the liquid outlet 511, which communicates with the liquid supplement port 322 to supplement the electrolyte to the electrochemical reaction chamber.

[0144] In some optional embodiments, the box body 510 further has a third side wall and a fourth side wall connected between the first side wall and the second side wall and arranged opposite in the horizontal direction. The outer surface of the third side wall and / or the fourth side wall is connected with a fixing member 517 having a screw hole for cooperating with a screw to fix the box body 510 to the mounting groove.

[0145] The refrigeration and freezing device 10 further comprises a liquid supplement pipeline 420 pre-embedded in the foaming layer, a first end of the liquid supplement pipeline 420 communicating with the liquid supplement port 322 of the oxygen treatment device 300, and a second end of the liquid supplement pipeline 420 communicating with the liquid outlet 511 of the liquid storage module 500 to guide the liquid flowing out of the liquid storage space from the liquid outlet 511 to the liquid supplement port 322, thereby supplementing the electrolyte to the electrochemical reaction chamber. The liquid outlet 511 is higher than the liquid supplement port 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.

[0146] Of course, in other examples, the liquid outlet 511 can also be changed to be lower than or level with the liquid supplement port 322. At this time, a pump can be installed on the liquid supplement pipeline 420 to drive the liquid in the liquid storage space to flow into the electrochemical reaction chamber under the action of the pump; or the siphon principle can be used to make the liquid in the liquid storage space flow into the electrochemical reaction chamber.

[0147] In some further examples, a one-way valve can be arranged on the liquid supplement pipeline 420 to allow the liquid from the liquid outlet to pass in one direction, thereby ensuring the one-way flow of the liquid flowing through the liquid supplement pipeline 420.

[0148] The refrigeration and freezing device 10 further comprises a filter pipeline 430 pre-embedded in the foaming layer, a first end of the filter pipeline 430 communicating with the exhaust hole 323 of the oxygen treatment device 300, and a second end of the filter pipeline 430 communicating with the air inlet 512 of the box body 510 to guide the oxygen flowing out of the exhaust hole 323 to the air outlet 513, thereby entering the liquid storage space for filtration.

[0149] The liquid storage module 500 can further include a filter tube 540 and an outlet tube. The filter tube 540 is inserted into the liquid storage space from the 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 dissolve in the liquid storage space. The outlet tube is inserted into the box body 510 from the outlet 513 and extends to the upper section of the liquid storage space and is located above the liquid stored in the liquid storage space to guide the filtered oxygen out of the outlet tube.

[0150] With the above scheme, the oxygen to be filtered can be guided by the filter tube 540 to the liquid storage space and flow through the liquid stored in the liquid storage space, so that the soluble impurities in the oxygen dissolve in the liquid storage space to complete the purification of the gas. The purified gas can flow into the designated space under the guidance of the outlet tube, thereby playing a role in adjusting the oxygen content of the space.

[0151] In an alternative embodiment, the liquid storage module 500 further includes a gas blocking mechanism 530 arranged in the liquid storage space and separating the liquid storage space into a filter gas zone and a non-filter gas zone with blocked gas path. The filter gas zone is used to make the gas flowing into the inlet 512 flow through it to achieve filtration. The non-filter gas zone is used to receive liquid from the outside.

[0152] The filter gas zone and the non-filter gas zone can be arranged in parallel along the transverse direction, and the gas blocking mechanism 530 blocks a part of the liquid path between the filter gas zone and the non-filter gas zone, so that the filter gas zone and the non-filter gas zone remain in liquid communication under the condition of blocked gas path. For example, the gas blocking mechanism 530 is a partition plate structure located between the filter gas zone and the non-filter gas zone and extending downward from the top wall lower surface of the box body 510 to form a gap with the bottom wall upper surface of the box body 510. The filter gas zone is located on one side of the gas blocking mechanism 530 in the transverse direction, and the non-filter gas zone is located on the other side of the gas blocking mechanism 530 in the transverse direction. The inlet 512 and the outlet 513 can be arranged on the top wall of the region where the filter gas zone is located. The liquid inlet 514 can be arranged on the top wall of the region where the non-filter gas zone is located.

[0153] With the above structure, by arranging the gas blocking mechanism 530 in the liquid storage space and separating the liquid storage space into the filter gas zone and the non-filter gas zone with blocked gas path by the gas blocking mechanism 530, the function of purifying the gas can be realized only in the filter gas zone. Since the filter gas zone is only a sub-space of the liquid storage space and the gas path between the filter gas zone and other regions of the liquid storage space is blocked, the gas flowing into the inlet 512 can only flow in the filter gas zone and cannot freely diffuse to the non-filter gas zone to cause slow discharge, so the liquid storage module 500 of the present embodiment has a high release rate of purified gas.

[0154] At this point, those skilled in the art will appreciate that although specific exemplary embodiments of the application have been described herein, the present application also encompasses many other variations or modifications in accordance with the principles of the application as set forth above. Accordingly, the scope of the present application should be understood to include all such variations and modifications.
