For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield still further embodiments. Accordingly, it is intended that the present invention cover such modifications and variations as come within the scope of the appended claims and their equivalents.

A refrigerating and freezing apparatus 10 according to an embodiment of the present invention will be described with reference to fig. 1 to 14. Wherein the references to the orientations or positional relationships of "inner", "outer", "upper", "lower", "top", "bottom", "front", "rear", "lateral", "horizontal", "vertical", etc., are based on the orientations or positional relationships shown in the drawings, are merely for purposes of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore are not to be construed as limiting the present invention.

Thus, a feature defining "a first", "a second", etc. may include at least one, i.e. one or more, of the feature, either explicitly or implicitly.

When a feature "comprises or includes" a feature or some of its coverage, this indicates that other features are not excluded and may further include other features, unless expressly stated otherwise.

In the description of the present embodiment, the descriptions of the terms "one embodiment," "some embodiments," "example," "one example," and the like, mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Embodiments of the present invention provide a refrigerated chiller 10. Fig. 1 is a schematic block diagram of a refrigeration and freezer 10 according to one embodiment of the invention. Fig. 2 is a schematic block diagram of the refrigeration and freezer 10 of fig. 1 from another perspective, with portions of the cabinet 100 omitted for ease of illustration of the internal structure. The refrigeration and freezer 10 may generally include a cabinet 100 and an air conditioning circuit 440.

The inside of the case 100 defines a first space and a second space that are disposed to be spaced apart from each other. The case 100 has a foaming layer. For example, the case 100 may further include a liner disposed inside the foaming layer, and the inner side of the liner may define a storage compartment. The foaming layer may be made of a heat insulating material such as polyurethane foam or the like.

The air-conditioning pipeline 440 is pre-buried in the foaming layer and connected between the first space and the second space to convey the air in the first space to the second space. The pre-embedding of the air conditioning line 440 in the foam layer means that the air conditioning line 440 is pre-positioned in the foam layer prior to the formation of the foam layer, and is not installed after the formation of the foam layer.

The first space and the second space may be formed at any position inside the case 100, for example, inside a storage compartment, a foaming layer, a compressor compartment, or an air duct, etc., respectively. The air conditioning line 440 may be used to deliver any gas, such as oxygen, nitrogen, etc., to condition the atmosphere of the second space.

The second space can regulate the internal atmosphere by using the external gas by embedding the air-conditioning pipeline 440 in the foaming layer and connecting the air-conditioning pipeline 440 between the first space and the second space to convey the gas of the first space to the second space. With the adoption of the scheme of the invention, the air conditioning pipeline 440 is pre-buried in the foaming layer and does not occupy the storage space, so that the refrigerating and freezing device 10 can condition the atmosphere of the space without affecting the effective volume.

In some alternative embodiments, the case 100 includes a first bladder 120 and a second bladder 150. The first liner 120 defines a first storage compartment 122 therein as a first space. The second liner 150 defines a second storage compartment 152 therein as a second space. That is, in the present embodiment, the air conditioning line 440 is connected between the first storage compartment 122 and the second storage compartment 152. For example, the first liner 120 and the second liner 150 may be provided with openings, respectively, as interfaces for connecting the air-conditioning duct 440.

With the above arrangement, the air conditioning line 440 may direct air from the first storage compartment 122 to the second storage compartment 152. When it is necessary to adjust the atmosphere of the second storage compartment 152, a gas supply device for generating gas may be disposed in the first storage compartment 122 as a gas supply end of the second storage compartment 152.

By using the first storage compartment 122 as the first space and the second storage compartment 152 as the second space and connecting the air-conditioning pipeline 440 between the first storage compartment 122 and the second storage compartment 152, an invisible air flow channel communicating the first storage compartment 122 and the second storage compartment 152 can be constructed by using the air-conditioning pipeline 440, so that air exchange can be realized between different storage compartments of the refrigeration and freezing device 10 based on the invisible air flow channel.

In a further example, the first liner 120 is a refrigerated liner. The second liner 150 is a chilled liner or a variable temperature liner.

Since the internal temperature of the refrigeration liner is relatively high and the internal temperature of the freezing liner or the temperature change liner is generally low, the gas from the first storage compartment 122 is guided to the second storage compartment 152 by the air conditioning pipeline 440, and the gas supply device is prevented from being directly arranged in the second storage compartment 152 with low temperature, so that the gas supply device is prevented from freezing.

When the first liner 120 is a refrigeration liner and the second liner 150 is a freezing liner or a temperature-changing liner, the first storage compartment 122 is used as a gas source of the second storage compartment 152, and the temperature of the first liner 120 is relatively high and the temperature of the second liner 150 is relatively low, so that the gas supply device can be arranged and maintained in the first storage compartment 122, and no gas supply device is directly arranged in the second storage compartment 152, which is beneficial to ensuring the normal operation of the gas supply device, thereby realizing the controlled atmosphere fresh-keeping of the temperature-changing compartment or the freezing compartment of the refrigeration and freezing device 10 in a low temperature state.

In some alternative embodiments, the refrigeration and freezer 10 further includes at least one first storage container 600 and an air path engagement member 860. Fig. 3 is a schematic internal configuration diagram of the refrigerating and freezing apparatus 10 shown in fig. 1. Fig. 4 is a schematic exploded view of the internal structure of the refrigerating and freezing apparatus 10 shown in fig. 3.

At least one first storage container 600 is disposed in the second storage compartment 152 and defines a first storage space therein. The wall of the first storage container 600 is provided with a vent 610 communicating with the first storage space.

The air passage engaging member 860 is fixed to the second liner 150 and has a first engaging port 861 communicating with the air outlet port of the air conditioning duct 440 and a second engaging port 862 communicating with the air vent 610. An air flow channel is connected between the first joint 861 and the second joint 862, so that the air conditioning pipeline 440 is communicated with the first storage space.

The first storage container 600 may be a closed storage container. With the above structure, the gas supplied to the second storage compartment 152 is guided into the first storage container 600 by the gas path joint 860, so that a proper fresh-keeping atmosphere can be created in the first storage container 600. Since the gas delivered to the second storage compartment 152 can be intensively guided into the first storage container 600, the solution of the present embodiment is advantageous for improving the air conditioning efficiency.

The air path engagement member 860 may be pre-fixed to the second liner 150, for example, may be pre-fixed to an opening of the second liner 150. In one example, the first engagement port 861 may protrude from the opening of the second liner 150 to the outside of the second liner 150 to interface with the air conditioning line 440. The second engagement opening 862 may extend to an inner side of the second liner 150 to interface with the air vent 610.

In some alternative embodiments, the first storage container 600 is a plurality. The air passage engagement members 860 have a plurality of second engagement openings 862 and are in one-to-one correspondence with the air passage 610 of each first storage container 600.

With the above structure, the same air-conditioning line 440 can be used to simultaneously condition the atmospheres of the plurality of first storage containers 600. Different food materials may be stored in different first storage containers 600 to prevent cross-flavor or mutual contamination.

In some alternative embodiments, the refrigeration and freezing apparatus 10 may further include a check valve disposed on the air-conditioning duct 440 for allowing the air flowing to the second space to pass through in one direction, which may ensure the air-delivery efficiency of the air-conditioning duct 440.

In some alternative embodiments, the refrigeration and freezer 10 also includes an air circuit assembly having an air vent line 820 in communication with the air vent 610 for delivering air to the first storage space. Fig. 5 is a partial enlarged view at a in fig. 4. The vent line 820 is fixed to the rear side of the first storage container 600. And the vent line 820 and the vent port 610 are nested and detachably disposed with each other during the drawing of the first storage container 600.

By arranging the air passage assembly in the storage room and enabling the air passage 820 and the air vent 610 of the air passage assembly to be mutually nested and detachably arranged in the drawing process of the first storage container 600, when the first storage container 600 is drawn out, the air vent 610 moves synchronously with the first storage container 600, so that the air passage 820 and the air vent 610 are detached and separated from each other, and when the first storage container 600 is reset, the air passage 820 and the air vent 610 can be restored to the mutually nested state so as to be mutually connected. With the above-described scheme of the present embodiment, the first storage container 600 may receive external air in a drawable condition to adjust the internal atmosphere.

In some alternative embodiments, the vent 610 is hollow and cylindrical and bulges outward from the back wall of the first storage container 600. One end of the vent line 820 has a hollow cylindrical interface into which the vent port 610 is nested.

When the vent 610 is hollow and cylindrical and bulges outward from the back wall of the first storage container 600, one end of the vent pipe 820 is set as a hollow cylindrical interface into which the vent 610 can be nested, and when the first storage container 600 is drawn out, the vent 610 is separated from the hollow cylindrical interface to realize the separation, and when the first storage container 600 is reset, the vent 610 can be reinserted into the hollow cylindrical interface to realize the nesting, because the vent 610 moves synchronously with the first storage container 600. With the above-described scheme of the present embodiment, it is ensured that the airtight connection between the first storage container 600 and the ventilation pipe 820 is achieved, so as to improve the air conditioning efficiency.

In some alternative embodiments, the gas circuit assembly also has a mounting bracket 850 secured within the second storage compartment 152. For example, the mounting bracket 850 may be fixedly coupled to an inner wall of the second storage compartment 152. The manner of fixing connection includes but is not limited to screwing, clamping, welding and riveting.

The mounting bracket 850 has a hollow cylindrical passage into which the vent line 820 is inserted to achieve a secure fit. That is, the vent line 820 is fixedly coupled to the mounting bracket 850 to achieve fixation.

By fixing the vent line 820 with the mounting bracket 850, the vent line 820 can be fixed at an arbitrary position away from the inner wall of the second storage compartment 152, improving the positional flexibility of the vent line 820.

In some alternative embodiments, the mounting bracket 850 includes a body portion 851 and a cover portion 852. The body portion 851 is fixed in the second storage compartment 152, and defines a concave arc plate that is concave downward and is arc-shaped. The concave arc plate serves as the lower channel wall of the hollow cylindrical channel.

The cover portion 852 defines an upwardly concave arcuate plate recessed upwardly and arcuate as the upper channel wall of the hollow cylindrical channel. The upper channel wall and the lower channel wall together form a fixation. The fixing portion defines a hollow cylindrical passage into which the vent pipe 820 is inserted to achieve a fixed fitting.

The body portion 851 and the cover portion 852 may be separately provided, not integrally formed. The body portion 851 and the cover portion 852 are utilized to define a hollow cylindrical channel together for arranging the vent pipe 820, and since the body portion 851 and the cover portion 852 can be separately and independently arranged, when the vent pipe 820 is assembled, the vent pipe 820 can be placed on the concave arc plate of the body portion 851, and then the cover portion 852 is fixed on the body portion 851, so that the vent pipe 820 can be stably assembled in the hollow cylindrical channel. And when the vent pipe 820 needs to be detached, the body part 851 and the cover body part 852 are separated, and the detachment process is simple.

The cover 852 is detachably assembled above the body 851. The cover portion 852 also defines a first threaded aperture on either side of the upper channel wall. The body portion 851 is formed with second screw holes located at both sides of the lower passage wall and in one-to-one correspondence with the first screw holes, to be detachably assembled by screw-coupling.

The vent 610 is located on the back wall of the first storage container 600. For example, the body portion 851 may be disposed against a back wall of the first storage container 600.

The mounting bracket 850 further includes a bending portion 854, which is formed by bending the end portion of the body portion 851 forward or backward, and is disposed against the sidewall of the second storage compartment 152. The bent portion 854 is provided with a third screw hole to fixedly assemble the mounting bracket 850 to the second locker room 152 by screw-coupling.

When the vent 610 is opened on the back wall of the first storage container 600, and the body portion 851 is fixed on the rear side of the first storage container 600, and the end portion of the body portion 851 is connected with the bent portion 854 bent forward, because the bent portion 851 can be fixedly connected with the side wall of the second storage compartment 152 by screwing, based on the above structure, the mounting bracket 850 of the air circuit assembly can be stably assembled in the second storage compartment 152 to fix the joint between the air-conditioning pipeline 440 and the vent 610, and on the other hand, the body portion 851 can be fixed at any position far away from the back wall of the second storage compartment 152, so that a sufficient space is reserved between the body portion 851 and the back wall of the second storage compartment 152 to arrange the pipeline.

The vent 610 is hollow and cylindrical in shape and protrudes outwardly from the back wall of the first storage container 600 and at least partially into the hollow cylindrical channel. The first end 821 of the vent conduit 820 defines a hollow cylindrical interface into which the vent port 610 is nested. In some alternative embodiments, the second end 822 of the vent line 820 has another hollow cylindrical interface. And the refrigeration and freezer 10 also includes a transfer line 810 communicating with the second end 822 of the vent line 820 for delivering a gas. Of course, the vent line 820 may also have a connection section connected between the first end 821 and the second end 822.

When the vent 610 is hollow and cylindrical and extends at least partially into the hollow cylindrical passage and is nested in the hollow cylindrical passage defined by the first end 821 of the vent line 820, the first storage container 600 is moved in a direction away from the vent line 820, so that the vent 610 is separated from the hollow cylindrical passage defined by the first end 821 of the vent line 820, and the first storage container 600 is moved in a direction close to the vent line 820, so that the vent 610 is re-nested in the hollow cylindrical passage defined by the first end 821 of the vent line 820, and therefore, based on the above structure, the gas path connection between the first storage container 600 and the air-conditioning line 440 can be achieved in a detachable manner.

Fig. 6 is a schematic structural view of the transfer line 810 of the refrigerating and freezing apparatus 10 shown in fig. 4. Fig. 7 is a schematic perspective view of the transfer line 810 of the refrigeration and freezer 10 shown in fig. 4. The interior of the transfer tubing 810 defines an air flow channel 813 that is disposed obliquely relative to the horizontal plane. The temperature of the first storage space is generally low. Since the transfer pipe 810 is directly connected to the vent 610 of the first storage container 600 via the vent pipe 820 and is closer to the first storage space, when the temperature of the first storage space is lower, the temperature of the transfer pipe 810 is correspondingly lower.

Through setting up the air current passageway 813 of transfer pipeline 810 for the horizontal plane slope, can make the contained angle between air current passageway 813 and the horizontal plane form acute angle or right angle, when the gas that flows through transfer pipeline 810 contains moisture and the temperature in first storing space is lower, the moisture that gas carried is difficult for detaining in air current passageway 813 inside, this is favorable to reducing or avoiding air current passageway 813 to block up because of producing the frost and dew, makes the gas exchange of sustainable ground between first storing space and its external environment realized, and then makes first storing space can maintain low temperature fresh-keeping atmosphere for a long time.

The adapting pipe 810 has a first port 811 connected to the ventilation pipe 440 and a second port 812 connected to the ventilation pipe 820, and the air flow channel 813 is connected between the second port 812 and the first port 811, so that the ventilation pipe 440 is connected to the ventilation port 610.

The first and second ports 811 and 812 are hollow cylindrical ports formed by outwardly bulging the outer surface of the swing pipe 810, respectively. The first interface 811 is nested and removably disposed with the second end of the air conditioning line 440. The second port 812 is nested with and detachably disposed from another hollow cylindrical port.

The interiors of the first and second ports 811 and 812 respectively define hollow passages communicating with the air flow passage 813 and disposed obliquely with respect to the horizontal plane. That is, the hollow passage of the first interface 811 and the hollow passage of the second interface 812 are also respectively provided obliquely.

With the above structure, since the hollow channel of each interface is communicated with the air flow channel 813, this is equivalent to extending the path of the inclined section of the transfer pipeline 810, so that the risk of air passage blockage of the transfer pipeline 810 can be further reduced, and the air-conditioning pipeline 440 and the air vent 610 can be kept in smooth connection.

In some alternative embodiments, the gas flow channel 813 of the transfer conduit 810 comprises a first channel section 813a and a second channel section 813b. Wherein 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 port 812.

The degree of inclination of the second channel section 813b is set to be different from that of the first channel section 813 a. 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 may result in different flow rates of the liquid carried by the gas when flowing through the first channel section 813a and the second channel section 813 b.

By arranging two channel sections with different inclinations in the transfer pipeline 810, on one hand, the connection mode between each channel section and the corresponding interface can be simplified, and on the other hand, because the flow rates of the gas when flowing through the first channel section 813a and the second channel section 813b are different, the risk of the gas channel 813 blocking can be further reduced by the above scheme of the embodiment.

In some alternative embodiments, the angle between the first channel section 813a and the horizontal is greater than the angle between the second channel section 813b and the horizontal.

By adopting the above scheme, when the air-conditioning pipeline 440 conveys air to the storage space, even if the liquid carried by the air may condense in the first channel section 813a and the second channel section 813b, since the liquid carried by the air may condense in the first channel section 813a first, the flow rate of the liquid beads is larger, and the liquid beads will wash the surface of the second channel section 813b when entering the second channel section 813b, and the liquid beads that condense in the second channel section 813b are wrapped and clamped to continue to flow forward at a high speed, thereby effectively reducing the risk of air path blockage of the transfer pipeline 810.

In some alternative embodiments, the first interface 811 is formed in an upper section of the transfer tubing 810, and the hollow passage inside the first interface 811 is disposed obliquely upward in a direction away from the outer surface of the transfer tubing 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 degree of inclination of the hollow channel inside the first interface 811 is the same as the degree of inclination of the first channel section 813 a.

The second port 812 is formed in a side section of the transfer pipe 810 and is located below the second port 812. The hollow passage inside the second port 812 is disposed obliquely downward in a direction away from the outer surface of the transfer tubing 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 hollow channel inside the second port 812 is inclined to the same extent as the second channel section 813 b.

Based on the above structure, the air conditioning line 440 may be connected to the upper portion of the transit line 810, and the ventilation line 820 may be connected to the side portion of the transit line 810.

In one example, the ports of the air conditioning line 440 may nest within the hollow channels of the first interface 811 and the vent line 820 may nest within the hollow channels of the second interface 812.

In one example, the vent line 820 is made of an elastic material. Because the vent line 820 made of an elastic material can be closely fitted to the port nested therein, the use of the vent line 820 to communicate the second port 812 with the vent port 610 enables airtight engagement between the second port 812 and the vent port 610.

In some alternative embodiments, the refrigerated chiller 10 also includes an oxygen treatment device 300. The oxygen treatment device 300 is disposed in the case 100, and has a housing 320 and an electrode pair, wherein an electrochemical reaction chamber for containing an electrolyte is defined in the housing 320, and the electrode pair is disposed in the electrochemical reaction chamber and is used for transferring external oxygen to the electrochemical reaction chamber through an electrochemical reaction. The casing 320 is provided with an exhaust hole 323 communicated with the electrochemical reaction chamber for exhausting oxygen in the electrochemical reaction chamber. The gas discharge hole 323 communicates with the first space and serves as a gas supply port of the air-conditioning line 440.

Fig. 8 is a schematic configuration view of an oxygen treatment device 300 of the refrigerating and freezing device 10 according to an embodiment of the present invention. Fig. 9 is a schematic exploded view of the oxygen treatment device 300 of the refrigeration and freezer 10 shown in fig. 8.

The electrode pair may include a cathode plate 330 and an anode plate 340. The electrochemical reaction bin is a place where the cathode plate 330 and the anode plate 340 perform electrochemical reaction, and can contain alkaline electrolyte, such as 1mol/L NaOH, and the concentration of the alkaline electrolyte can be adjusted according to actual needs.

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 face of the housing 320, such as a top face, a bottom face, or a side face. In one example, the lateral opening 321 may be disposed on a face of the housing 320 where the area is greatest.

The cathode plate 330 is disposed at the lateral opening 321 to define an electrochemical reaction chamber for containing an electrolyte together with the case 320, and serves to consume oxygen of the second storage space through an electrochemical reaction. Oxygen in the air may undergo a reduction reaction at the cathode plate 330, namely: o (O) ₂ +2H ₂ O+4e ^- →4OH ^- 。

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

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

The first end of the air conditioning line 440 may be in direct communication with the transfer line 810. The second end of the air conditioning line 440 may be in direct or indirect communication with the exhaust aperture 323.

In some alternative embodiments, the housing 320 is provided with a fluid refill port 322 that communicates with the electrochemical reaction cartridge. The refrigeration and freezing device 10 further comprises a liquid storage module 500, which is disposed in the box 100 and has a box 510, wherein a liquid storage space for storing liquid is defined in the box 510, and the liquid storage space is communicated with the liquid supplementing port 322 to supplement electrolyte to the electrochemical reaction bin. The liquid in the liquid storage space can be water or electrolyte, and the concentration of the liquid can be lower than that of the electrolyte in the electrochemical reaction bin.

In one example, the cartridge 510 may be disposed within the first space.

The top wall of the box 510 is provided with an air inlet 512 and an air outlet 513. Wherein the air inlet 512 is connected to the air outlet 323 to allow the oxygen discharged from the air outlet 323 to be introduced into the liquid storage space to filter soluble impurities, such as electrolyte carried by the oxygen. The air outlet 513 is configured to allow the filtered oxygen to be discharged to the outside, and the air outlet 513 is in communication with the first space and directly communicates with an air inlet port of the air conditioning duct 440 for allowing the filtered oxygen to be discharged to the air conditioning duct.

With the above structure, the air conditioning pipeline 440 can deliver clean oxygen to the first storage space.

In one example, the refrigeration and freezer 10 further includes a second storage container 700 disposed within the first space and defining a second storage space therein. The wall of the second storage container 700 is provided with a ventilation port communicated with the second storage space. The cathode plate 330 of the oxygen treatment device 300 is in gas flow communication with the second storage space to reduce the oxygen content of the second storage space by an electrochemical reaction. For example, the housing 320 may be provided with lateral openings 321. The lateral opening 321 may be facing the transfer port. The cathode plate 330 is disposed at the lateral opening 321 to define an electrochemical reaction chamber for containing an electrolyte together with the case 320 and to close the ventilation port, and to consume oxygen of the second storage space through an electrochemical reaction. In this example, an oxygen treatment device may be disposed within the first space and conceal the ventilation port such that the cathode plate 330 is in gas flow communication with the second storage space.

In one example, the oxygen treatment device 300 may be disposed within a foaming layer. Fig. 10 is a schematic structural view of a refrigerating and freezing apparatus according to an embodiment of the present invention, and fig. 11 is a schematic internal structural view of the refrigerating and freezing apparatus shown in fig. 10, in which a foaming layer is omitted for convenience in illustrating the structure and connection relationship of the respective components. In this case, the refrigerating and freezing apparatus 10 may further include a ventilation line 200 embedded in the foaming layer. The ventilation circuit 200 may include an intake circuit 210 and a return circuit 220.

The gas inlet pipe 210 is used for guiding the gas in the second storage space to the cathode plate 330, and the gas return pipe 220 is used for guiding the gas flowing through the cathode plate 330 back to the second storage space so as to reduce the oxygen content in the second storage space. For example, the liner wall of the liner 120 is provided with a first ventilation port communicating with the first end of the intake conduit 210 and a second ventilation port communicating with the first end of the return conduit 220. Each ventilation opening is an opening formed in the liner wall of the liner 120. The second end of the air inlet pipe 210 and the second end of the air return pipe 220 may communicate with both ends of the cathode plate 330, respectively, and in particular, the second end of the air inlet pipe 210 may communicate with an upwind side of the cathode plate 330, and the second end of the air return pipe 220 may communicate with a downwind side of the cathode plate 330, so that the gas flowing out of the air inlet pipe 210 may flow into the air return pipe 220 after flowing through the cathode plate 330.

With the above structure, the air inlet pipeline 210 and the air return pipeline 220 are used to communicate the second storage space with the oxygen treatment device 300, and the gas with higher oxygen content in the second storage space can flow to the cathode plate 330 through the air inlet pipeline 210, so that the cathode plate 330 can perform electrochemical reaction by using the oxygen in the gas as a reactant to form low-oxygen gas with lower oxygen content, and the low-oxygen gas can return to the second storage space through the air return pipeline 220, thereby playing a role of reducing the oxygen content in the second storage space.

The oxygen treatment device 300 may be provided at any portion of the foam layer, for example, at the back of the liner 120, or at the top, bottom, and side of the liner 120. For a french refrigerator or a T-type refrigerator, in one example, the oxygen treatment device 300 may be disposed in a gap between the upper liner 120 and the lower liner 120.

In some alternative embodiments, a side of the foam layer facing away from the inner bladder 120 is provided with an assembly groove that communicates with the exterior environment of the foam layer for assembly of the oxygen treatment device 300.

After the foaming layer is formed, the oxygen treatment device 300 may be fitted into the fitting groove so as to be disposed in the foaming layer. The assembly grooves can be reserved in the foaming layer forming process. The fitting groove is recessed toward a direction approaching the inner container 120 in a thickness direction of the foaming layer, and forms a gap with the inner container 120. In other words, the fitting groove does not penetrate the foaming layer, so that the oxygen treatment device 300 fitted to the fitting groove does not cling to the inner container 120. That is, a certain thickness of heat insulating material is formed between the liner 120 and the oxygen treatment device 300.

With the above structure, the assembly groove communicated with the external environment of the foaming layer is formed on the side of the foaming layer opposite to the inner container 120, and a gap is formed between the assembly groove and the inner container 120, so that the oxygen treatment device 300 can be mounted in the assembly groove after the foaming layer is formed, which is beneficial to simplifying the disassembly and assembly difficulty of the oxygen treatment device 300. Moreover, the oxygen treatment device 300 is not closely attached to the liner 120, so that the low-temperature environment of the refrigerating and freezing device 10 can be reduced or avoided from affecting the normal operation of the electrochemical reaction.

Oxygen treatment device 300 may be secured within the assembly recess by, but not limited to, bolting, clamping, riveting, welding, and bonding.

In some alternative embodiments, the case 100 further includes a case 170 covering the outer side of the foaming layer to clamp the foaming layer with the liner 120. The case 170 has a back plate, and an assembly groove is formed between the back wall of the liner 120 and the back plate of the case 170. That is, the oxygen treatment device 300 of the present embodiment is disposed in the foaming layer at the back of the liner 120. The back plate of the case 170 may close the opening of the fitting groove to make the external appearance beautiful.

In one example, the back plate of the case 170 may be provided with a mounting hole facing the mounting groove, and the oxygen treatment device 300 may be directly fixed into the mounting groove through the mounting hole without disassembling the back plate of the case 170 during the assembly. In a further example, a cover plate may be provided at the mounting opening for shielding the mounting opening for aesthetic appearance. In another example, the oxygen treatment device 300 may be fixed into the fitting groove first, and then the back plate of the case 170 may be covered on the back of the foaming layer.

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

In yet another example, a compressor compartment for mounting a compressor is also defined within the housing 100. Oxygen treatment device 300 may be disposed within a compressor compartment. For example, the bottom of the compressor compartment is provided with a support plate for fixing the compressor, and the oxygen treatment device 300 may be directly or indirectly provided on the support plate.

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

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

In some alternative embodiments, the case 100 further has a case, and the foaming layer is formed between the case and the inner container 120. The case housing is provided outside the foaming layer to sandwich the foaming layer with the inner container 120. In one example, a refrigeration and freezing device may include a refrigeration liner, a temperature change liner, and a freezing liner. In a further example, the box may be disposed within a foam layer outside of the refrigerated liner.

Fig. 12 is a schematic configuration view of the liner 120 of the refrigerating and freezing apparatus 10 according to an embodiment of the present invention. The inner container 120 is provided with an opening-shaped interaction window 124, and the foaming layer is provided with an installation groove communicated with the interaction window 124 for assembling the liquid storage module 500. After the foaming layer is molded, the liquid storage module 500 may be fitted into the installation groove so as to be disposed in the foaming layer. The mounting groove can be reserved in the foaming layer forming process. The mounting groove is recessed in a thickness direction of the foaming layer toward a direction away from the interactive window 124, and forms a gap with the case. In other words, the mounting groove does not penetrate the foaming layer, so that the liquid storage module 500 fitted to the mounting groove does not cling to the case. That is, a certain thickness of heat insulating material is formed between the casing and the oxygen treatment device 300.

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

Through seting up interactive window 124 on the inner bag 120 to set up the installation recess that communicates with each other with interactive window 124 in the foaming layer, and make and form the clearance between installation recess and the case, the stock solution module 500 can be installed to the installation recess again after the foaming layer shaping, this is favorable to simplifying the dismouting degree of difficulty of stock solution module 500. And because the mounting groove does not penetrate through the foaming layer, the solution of the embodiment can reduce or avoid the obvious reduction of the heat insulation performance of the refrigeration and freezing device 10 caused by the mounting of the liquid storage module 500 in the foaming layer.

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

In some alternative embodiments, the case 510 is provided with a filling port 514 communicating with the liquid storage space, and the filling port 514 is exposed through the interaction window 124, so as to allow the external liquid to be filled into the liquid storage space. Fig. 13 is a schematic configuration view of a liquid storage module of the refrigerating and freezing apparatus shown in fig. 11. Fig. 14 is a schematic perspective view of a reservoir module of the refrigeration and freezer of fig. 13. For example, the filling port 514 is disposed on a side wall of the box 510 facing the second storage compartment, so as to be exposed through the interaction window 124.

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

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

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

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

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

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

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

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

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

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

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

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

The fill port 514 may be disposed in an upper section of the first sidewall. The viewable area 516 may also be disposed on the first sidewall, such as in a middle section or a lower section of the first sidewall.

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

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

The refrigeration and freezing device 10 further comprises a liquid supplementing pipeline 420 pre-buried in the foaming layer, wherein a first end of the liquid supplementing pipeline 420 is communicated with the liquid supplementing port 322 of the oxygen treatment device 300, and a second end of the liquid supplementing pipeline 420 is communicated with the liquid outlet 511 of the liquid storage module 500 so as to guide liquid flowing out of the liquid storage space from the liquid outlet 511 to the liquid supplementing port 322, thereby supplementing liquid to the electrochemical reaction bin. The liquid outlet 511 is higher than the liquid supplementing inlet 322, so that the liquid in the liquid storage space can automatically flow into the electrochemical reaction bin under the action of gravity without a power device.

Of course, in other examples, the outlet 511 may be lower than the fluid-filling port 322 or be level with the fluid-filling port 322. At this time, a pump may be installed on the fluid infusion line 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 bin by utilizing the siphon principle.

In some further examples, the fluid replacement line 420 may be provided with a one-way valve for allowing one-way passage of fluid from the fluid outlet 511, ensuring one-way flow of fluid through the fluid replacement line 420.

The refrigerating and freezing apparatus 10 further includes a filtering pipeline 430 pre-buried in the foaming layer, a first end of the filtering pipeline 430 is communicated with the air outlet 323 of the oxygen treatment device 300, and a second end of the filtering pipeline 430 is communicated with the air inlet 512 of the box body 510, so that oxygen flowing out from the air outlet 323 is guided to the air outlet 513, and then enters the liquid storage space for filtering.

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

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

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

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

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

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