Background technique

Controlled atmosphere preservation technology is a technology that extends the storage life of food by adjusting the composition of ambient gases. Refrigeration and freezing devices with controlled atmosphere preservation functions are widely popular. Among the many gas components, oxygen has attracted much attention. The oxygen treatment device can process oxygen through the electrochemical reaction of the electrode to create a low-oxygen preservation atmosphere or a high-oxygen preservation atmosphere.

The inventor realized that when pipelines are used to connect different spaces, gas exchange can occur in the interconnected spaces, thereby adjusting the internal gas composition. However, adding pipelines will have a significant impact on the structural layout of the refrigeration and freezing device, compressing the effective volume of the refrigeration and freezing device. The oxygen treatment device has a certain volume and requires a certain installation space.

Detailed ways

The refrigeration and freezing device 10 according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 19 . An embodiment of the present invention provides a refrigeration and freezing device 10. The refrigeration and freezing device 10 in the embodiment of the present invention may be a refrigerator, or a refrigeration equipment with a low-temperature storage function such as a refrigerator, a freezer, or a refrigerator. The refrigeration and freezing device 10 may generally include a box 100, a ventilation pipeline 200, an oxygen treatment device 300 and an air conditioning pipeline 440.

The interior of the box 100 defines a first space and a second space spaced apart from each other. The box body 100 has a foam layer. For example, the box 100 may further include an inner bladder disposed inside the foam layer, and the inner side of the inner bladder may define a storage compartment.

The air conditioning pipeline 440 is pre-embedded in the foam layer and connected between the first space and the second space to transport the gas in the first space to the second space. The fact that the air conditioning pipeline 440 is pre-embedded in the foam layer means that the air conditioning pipeline 440 is pre-positioned in the foam layer before the foam layer is formed, and is not installed after the foam layer is formed.

The first space and the second space can be formed at any position inside the box 100, such as inside the storage room, inside the foam layer, inside the compressor room, or inside the air duct, etc. The air conditioning pipeline 440 can be used to transport any gas, such as oxygen, nitrogen, etc., to adjust the atmosphere of the second space.

By pre-embedding the air conditioning pipeline 440 in the foam layer and connecting the air conditioning pipeline 440 between the first space and the second space to transport the gas in the first space to the second space, the second space can be The space uses external air to regulate the internal atmosphere. Using the solution of the present invention, since the air conditioning pipeline 440 is pre-embedded in the foam layer and does not occupy the storage space, the refrigeration and freezing device 10 can adjust the atmosphere of the space without affecting the effective volume.

In some optional embodiments, the box 100 includes a first inner bladder 120 and a second inner bladder 150 . The interior of the first inner bag 120 defines a first storage compartment 122 as the first space. The interior of the second inner bladder 150 defines a second storage compartment 152 as a second space. That is to say, in this embodiment, the air conditioning pipeline 440 is connected between the first storage compartment 122 and the second storage compartment 152 . For example, the first inner bag 120 and the second inner bag 150 may respectively have openings as interfaces for connecting the air conditioning pipeline 440 .

Using the above solution, the air conditioning pipeline 440 can guide the gas 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 arranged in the first storage compartment 122 as a gas supply end of the second storage compartment 152 .

The first storage compartment 122 is used as the first space, the second storage compartment 152 is used as the second space, and the air conditioning pipeline 440 is connected to the first storage compartment 122 and the second storage compartment. Between the chambers 152, the air conditioning pipeline 440 can be used to construct an invisible airflow channel connecting the first storage compartment 122 and the second storage compartment 152. Thus, between different storage compartments of the refrigeration and freezing device 10 Gas exchange can be achieved based on invisible air flow channels. Among them, the first inner tank 120 is a refrigerated inner tank. The second inner pot 150 is a freezing inner pot or a temperature-changing inner pot.

Since the internal temperature of the refrigerated liner is relatively high, while the internal temperature of the refrigerated liner or the variable temperature liner is generally low, the air conditioning pipeline 440 is used to guide the gas from the first storage compartment 122 to the second storage. compartment 152, it is possible to avoid arranging the gas supply device directly in the second storage compartment 152 with a lower temperature to prevent the gas supply device from freezing.

When the first inner pot 120 is a refrigerated inner pot, and the second inner pot 150 is a freezing inner pot or a temperature-changing inner pot, the first storage compartment 122 serves as the gas source of the second storage compartment 152. Since the first inner pot 120 is a refrigerated inner pot, The temperature of the bladder 120 is relatively high, while the temperature of the second inner bladder 150 is relatively low. Therefore, the gas supply device can be arranged and maintained in the first storage compartment 122 without being directly arranged in the second storage compartment 152 Any gas supply device, this is helpful to ensure the normal operation of the gas supply device, so that the temperature-changing compartment or the freezing compartment of the refrigeration and freezing device 10 can achieve controlled atmosphere preservation at low temperatures.

In some optional embodiments, the refrigeration and freezing device 10 further includes at least one first storage container 600 and a gas path joint 860 .

An air flow channel is connected between the first joint port 861 and the second joint port 862, so that the air conditioning pipeline 440 is connected to the first storage space.

The first storage container 600 may be a closed storage container. Using the above structure, the gas path joint 860 is used to guide the gas delivered to the second storage compartment 152 into the first storage container 600, so that a suitable freshness preservation atmosphere can be created in the first storage container 600. Since the gas delivered to the second storage compartment 152 can be centrally guided into the first storage container 600, the solution of this embodiment is beneficial to improving the air conditioning efficiency.

The air path joint 860 can be pre-fixed on the second inner bag 150 , for example, it can be pre-fixed on the opening of the second inner bag 150 . In one example, the first coupling port 861 can extend from the opening of the second liner 150 to the outside of the second liner 150 to connect with the air conditioning pipeline 440 . The second joint opening 862 may extend to the inner side of the second inner bladder 150 to connect with the ventilation opening 610 .

In some optional embodiments, there are multiple first storage containers 600 . There are a plurality of second joint openings 862 of the air path joint member 860 , and they are connected to the ventilation openings 610 of each first storage container 600 in a one-to-one correspondence.

Using the above structure, the same air conditioning pipeline 440 can be used to adjust the air of multiple first storage containers 600 at the same time. atmosphere. Different food ingredients can be stored in different first storage containers 600 to prevent odor mixing or mutual contamination.

In some optional embodiments, the refrigeration and freezing device 10 may further include a one-way valve disposed on the air conditioning pipeline 440 to allow gas flowing to the second space to pass in one direction, which can ensure that the air conditioning pipe The gas delivery efficiency of Road 440.

FIG. 5 is a partial enlarged view of position A in FIG. 4 . The ventilation pipe 820 is fixed on the rear side of the first storage container 600 . And the ventilation pipe 820 and the ventilation port 610 are nested with each other and detachably arranged during the drawing process of the first storage container 600 .

By arranging the air circuit assembly in the storage room, and allowing the ventilation pipe 820 and the ventilation port 610 of the air circuit assembly to be nested with each other and detachable during the pulling process of the first storage container 600, When the first storage container 600 is extracted, since the vent 610 moves synchronously with the first storage container 600, the vent pipe 820 and the vent 610 are disengaged and separated from each other. When the first storage container 600 When resetting, the ventilation pipeline 820 and the ventilation port 610 can return to a mutually nested state, thereby being connected to each other. Using the above solution of this embodiment, the first storage container 600 can receive external air while being pullable to adjust the internal atmosphere.

In some optional embodiments, the vent 610 is hollow cylindrical and protrudes outward from the back wall of the first storage container 600 . One end of the ventilation pipeline 820 has a hollow cylindrical interface in which the ventilation port 610 is nested.

When the vent 610 is hollow 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 for the vent 610 to be nested therein. When the storage container 600 is pulled out, since the vent 610 moves synchronously with the first storage container 600, the vent 610 comes out of the hollow cylindrical interface to achieve disengagement. When the first storage container 600 is reset, the vent 610 610 can be inserted again into the hollow cylindrical interface to achieve nesting. Using the above solution of this embodiment, it is possible to ensure airtight connection between the first storage container 600 and the ventilation pipe 820, thereby improving the air conditioning efficiency.

In some optional embodiments, the air circuit assembly also has a mounting bracket 850 that is fixed in the second storage compartment 152 . For example, the mounting bracket 850 may be fixedly connected to the inner wall of the second storage compartment 152 . Methods of fixed connection include but are not limited to screwing, clamping, welding, and riveting.

The mounting bracket 850 has a hollow cylindrical channel into which the vent pipe 820 is inserted to achieve fixed assembly. That is to say, the ventilation pipeline 820 is fixedly connected to the mounting bracket 850 to achieve fixation. By using the mounting bracket 850 to fix the ventilation pipe 820, the ventilation pipe 820 can be fixed at any position away from the inner wall of the second storage compartment 152, which improves the position flexibility of the ventilation pipe 820.

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

The cover body portion 852 defines an upwardly concave arc-shaped plate that is concave and arc-shaped as the upper channel wall of the hollow cylindrical channel. The upper channel wall and the lower channel wall together form a fixing part. The fixing portion defines a hollow cylindrical channel into which the vent line 820 is inserted to achieve a fixed assembly.

The main body part 851 and the cover body part 852 can be separately provided and are not integrally formed. The body part 851 and the cover part 852 jointly define a hollow cylindrical channel for arranging the ventilation pipe 820. Since the body part 851 and the cover part 852 can be separated and independently arranged, when assembling the ventilation pipe 820, it is possible to First place the ventilation pipe 820 on the concave arc plate of the body part 851, and then fix the cover part 852 on the body part 851. In this way, the ventilation pipe 820 can be stably assembled in the hollow cylindrical shape. inside the channel. And when it is necessary to disassemble the ventilation pipe 820, just separate the body part 851 and the cover part 852, and the disassembly process is simple.

The cover portion 852 is detachably assembled above the main body portion 851 . The cover portion 852 also defines first threaded holes on both sides of the upper channel wall. The body part 851 is correspondingly formed with second threaded holes located on both sides of the lower channel wall and opposite to the first threaded holes, so as to achieve detachable assembly through screwing.

The vent 610 is located on the back wall of the first storage container 600 . For example, the body part 851 may be disposed in close contact with the back wall of the first storage container 600 . The mounting bracket 850 also includes a bent portion 854. The bent portion 854 is formed from the main body portion. The end of 851 is formed by bending forward or backward, and is disposed in close contact with the side wall of the second storage compartment 152 . The bent portion 854 is provided with a third threaded hole for fixing the mounting bracket 850 to the second storage compartment 152 through screw connection.

When the ventilation opening 610 is opened on the back wall of the first storage container 600, the body part 851 is fixed to the rear side of the first storage container 600, and the end of the body part 851 is connected to a forwardly bent bend. When the portion 854 is formed, the bent portion 851 can be fixedly connected to the side wall of the second storage compartment 152 through screwing. Therefore, based on the above structure, on the one hand, the mounting bracket 850 of the air path assembly can be stably assembled on the In the second storage compartment 152, the joint between the air conditioning pipeline 440 and the vent 610 is fixed. On the other hand, the body part 851 can be fixed at any position away from the back wall of the second storage compartment 152. Enough space is reserved between the body part 851 and the back wall of the second storage compartment 152 for arranging pipelines.

The vent 610 is in the shape of a hollow column, and it protrudes outward from the back wall of the first storage container 600 and at least partially extends into the hollow cylindrical channel. The first end 821 of the vent line 820 defines a hollow cylindrical interface into which the vent 610 is nested. In some optional embodiments, the second end 822 of the vent line 820 has another hollow cylindrical interface. And the refrigeration and freezing device 10 also includes a transfer pipeline 810 that communicates with the second end 822 of the ventilation pipeline 820 and is used to transport gas. Of course, the ventilation pipeline 820 may also have a connection section connected between the first end 821 and the second end 822 .

When the vent 610 is hollow cylindrical and at least partially extends into the hollow cylindrical channel and is nested within the hollow cylindrical channel defined by the first end 821 of the vent pipe 820, along the direction away from the vent pipe 820 By moving the first storage container 600 in the direction, the ventilation opening 610 can escape from the hollow cylindrical channel defined by the first end 821 of the ventilation pipeline 820, and by moving the first storage container 600 in the direction close to the ventilation pipeline 820, the ventilation opening 610 can be The vent 610 is re-nested in the hollow cylindrical channel defined by the first end 821 of the vent pipe 820. Therefore, based on the above structure, the gap between the first storage container 600 and the air conditioning pipe 440 can be The gas line connection is achieved in a detachable manner.

FIG. 6 is a schematic structural diagram of the transfer pipeline 810 of the refrigeration and freezing device 10 shown in FIG. 4 . FIG. 7 is a schematic perspective view of the transfer pipeline 810 of the refrigeration and freezing device 10 shown in FIG. 4 . The interior of the transfer pipe 810 defines an air flow channel 813 that is inclined relative to the horizontal plane. The temperature of the first storage space is generally lower. Since the transfer pipeline 810 is directly connected to the ventilation port 610 of the first storage container 600 via the ventilation pipeline 820 and is close to the first storage space, when the temperature of the first storage space is low, the transfer pipeline 810 The temperature of the connecting pipe 810 is also correspondingly lower.

By arranging the air flow channel 813 of the transfer pipe 810 to be inclined relative to the horizontal plane, the angle between the air flow channel 813 and the horizontal plane can form an acute or right angle. When the gas flowing through the transfer pipe 810 contains moisture and the first storage space When the temperature is low, the moisture carried by the gas is not easy to stay inside the air flow channel 813, which is helpful to reduce or avoid the air flow channel 813 being blocked due to frost and dew, and achieve sustainability between the first storage space and its external environment. Ground gas exchange enables the first storage space to maintain a low-temperature preservation atmosphere for a long time.

The transfer pipeline 810 has a first interface 811 connected to the air conditioning pipeline 440 and a second interface 812 connected to the ventilation pipeline 820, and the above-mentioned air flow channel 813 is connected between the second interface 812 and the first interface 811, so that the air conditioning The pipeline 440 is connected to the vent 610 .

The first interface 811 and the second interface 812 are respectively hollow cylindrical interfaces formed by bulging outward from the outer surface of the transfer pipe 810 . The first interface 811 and the second end of the air conditioning pipeline 440 are nested with each other and are detachably provided. The second interface 812 and another hollow cylindrical interface are nested in each other and are detachably arranged.

The interiors of the first interface 811 and the second interface 812 respectively define hollow passages that communicate with the airflow passage 813 and are 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 arranged at an angle.

With the above structure, since the hollow channel of each interface is connected to the air flow channel 813, this is equivalent to extending the path of the inclined section of the transfer pipeline 810, which can further reduce the risk of air blockage in the transfer pipeline 810, making Maintain a smooth connection between the air conditioning pipeline 440 and the vent 610 .

In some optional embodiments, the airflow channel 813 of the transfer pipeline 810 includes a first channel section 813a and a second channel section 813b. Among them, the first channel section 813a is connected to the hollow channel inside the first interface 811. The second channel section 813b is connected to the first channel section 813a and to the hollow channel inside the second interface 812 .

The degree of inclination of the second channel section 813b is set to be different from the degree of inclination 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 will cause the liquid carried by the gas to flow through the first channel section 813a and the second channel section 813a. The flow rates of the two channel sections 813b are different.

By arranging two channel sections with different inclinations in the transfer pipeline 810, on the one hand, the connection method between each channel section and the corresponding interface can be simplified, and on the other hand, since the gas flows through the first channel section 813a The flow rate is different from that in the second channel section 813b. Therefore, the above solution of this embodiment can further reduce the risk of airway blockage in the airflow channel 813.

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.

Using the above solution, when the air conditioning pipeline 440 delivers gas to the storage space, even the liquid carried by the gas may condense in the first channel section 813a and the second channel section 813b, because the liquid carried by the gas It will first condense in the first channel section 813a, and the flow rate of the liquid droplets is relatively large. When these liquid beads enter the second channel section 813b, they will wash the surface of the second channel section 813b, enveloping the second channel section 813b. The condensed liquid beads continue to flow forward at a high speed, thereby effectively reducing the risk of air blockage in the transfer pipeline 810 .

In some optional embodiments, the first interface 811 is formed in the upper section of the transfer pipeline 810 , and the hollow channel inside the first interface 811 is inclined upward in a direction away from the outer surface of the transfer pipeline 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 to say, the inclination degree of the hollow channel inside the first interface 811 is the same as the inclination degree of the first channel section 813a.

The second interface 812 is formed in a side section of the transfer pipe 810 and is located below the second interface 812 . The hollow channel inside the second interface 812 is inclined downward in a direction away from the outer surface of the transfer pipe 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 the inclination degree of the second channel section 813b.

Based on the above structure, the air conditioning pipeline 440 can be connected to the upper part of the transfer pipeline 810 , and the ventilation pipeline 820 can be connected to the side of the transfer pipeline 810 .

In one example, the port of the air conditioning pipeline 440 can be nested in the hollow channel of the first interface 811 , and the ventilation pipeline 820 can be nested in the hollow channel of the second interface 812 .

In one example, vent line 820 is made of elastic material. Since the ventilation pipe 820 made of elastic material can closely fit the interface nested therein, using the ventilation pipe 820 to connect the second interface 812 and the ventilation port 610 can make the second interface 812 and the ventilation port 610 are airtightly joined.

The cathode plate 330 is disposed at the lateral opening 321 to jointly define an electrochemical reaction chamber for containing electrolyte with the housing 320, and for consuming oxygen in the second storage space through electrochemical reaction. Oxygen in the air can undergo a reduction reaction at the cathode plate 330, namely: O ₂ +2H ₂ O+4e ^- → 4OH ^- .

The anode plate 340 and the cathode plate 330 are spaced apart from each other in the electrochemical reaction chamber, and are used to provide reactants to the cathode plate 330 and generate oxygen through electrochemical reactions, so as to transfer the oxygen in the second storage space to the electrochemical reaction chamber. Reaction chamber. The OH ^- generated by the cathode plate 330 can undergo an oxidation reaction at the anode plate 340 and generate oxygen, that is: 4OH ^- →O ₂ +2H ₂ O+4e ^- .

The above examples of the electrochemical reaction of the cathode plate 330 and the anode plate 340 are only illustrative. Based on understanding the above embodiments, those skilled in the art should easily change the type of electrochemical reaction, or adapt it to other electrochemical reactions.

To replenish electrolyte to the electrochemical reaction chamber. The liquid contained in the liquid storage space may be water or electrolyte, and its concentration may be lower than the electrolyte contained in the electrochemical reaction chamber. Among them, the box body 510 can be disposed in the first space.

An air inlet 512 and an air outlet 513 are provided on the top wall of the box 510 . The air inlet 512 is connected to the exhaust hole 323 to allow the oxygen discharged from the exhaust hole 323 to pass into the liquid storage space to filter soluble impurities, such as the electrolyte carried by the oxygen. The air outlet 513 is used to allow filtered oxygen to be discharged to the outside. The air outlet 513 is connected to the first space and directly connected to the air inlet port of the air conditioning pipeline 440, and is used to allow filtered oxygen to be discharged into the air conditioning pipeline.

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

In one example, the refrigeration and freezing device 10 further includes a second storage container 700 , which is disposed in the first space and defines a second storage space inside. The wall of the second storage container 700 is provided with a ventilation opening communicating with the second storage space. The cathode plate 330 of the oxygen treatment device 300 is in air flow communication with the second storage space, thereby reducing the oxygen content in the second storage space through an electrochemical reaction. For example, the housing 320 may be provided with lateral openings 321 . The lateral opening 321 may face the ventilation port. The cathode plate 330 is disposed at the lateral opening 321 to jointly define an electrochemical reaction chamber for containing electrolyte and sealing the ventilation port with the casing 320, and is used to consume oxygen in the second storage space through electrochemical reaction. In this example, the oxygen treatment device can be disposed in the first space and cover the ventilation opening, so that the cathode plate 330 is in airflow communication with the second storage space.

In one example, the oxygen treatment device 300 may be disposed within the foam layer. Figure 10 is a schematic structural diagram of a refrigeration and freezing device according to an embodiment of the present invention. Figure 11 is a schematic internal structural diagram of the refrigeration and freezing device shown in Figure 10. In order to facilitate illustrating the structure and connection relationship of each component, in the figure The foaming layer is hidden. At this time, the refrigeration and freezing device 10 may further include a ventilation pipeline 200 embedded in the foam layer. The ventilation pipeline 200 may include an air intake pipeline 210 and a return air pipeline 220 .

The air inlet pipeline 210 is used to guide the gas in the second storage space to the cathode plate 330, and the return air pipeline 220 is used to guide the gas flowing through the cathode plate 330 back to the second storage space to lower the second storage space. The oxygen content of the space. For example, a first ventilation port connected to the first end of the air inlet pipeline 210 and a second ventilation port connected to the first end of the return air pipeline 220 are formed on the wall of the inner tank 120 . Each ventilation port is an opening formed on the wall of the inner bladder 120 . The second end of the air inlet pipe 210 and the second end of the return air pipe 220 can be connected to the two ends of the cathode plate 330 respectively. Specifically, the second end of the air inlet pipe 210 can be connected to the upwind side of the cathode plate 330 and the return air pipe. The second end of 220 can be connected to the leeward side of the cathode plate 330, so that the gas flowing out of the air inlet pipe 210 can flow into the return air pipe 220 after flowing through the cathode plate 330.

Using the above structure, the air inlet pipeline 210 and the return air pipeline 220 are used to connect the second storage space and the oxygen place. In the management device 300, the gas with a higher oxygen content in the second storage space can flow to the cathode plate 330 through the air inlet pipe 210, so that the cathode plate 330 uses the oxygen in it as a reactant to perform an electrochemical reaction to form a gas with a higher oxygen content. Low oxygen gas, these low oxygen gases can be returned to the second storage space through the return pipeline 220, thereby reducing the oxygen content in the second storage space.

The oxygen treatment device 300 can be disposed at any part of the foam layer, for example, it can be disposed on the back of the liner 120 , or can be disposed on the top, bottom, and side of the liner 120 . For a French-style refrigerator or a T-type refrigerator, in one example, the oxygen treatment device 300 may be disposed in the gap between the upper inner pot 120 and the lower inner pot 120 .

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

After the foam layer is formed, the oxygen treatment device 300 can be assembled into the assembly groove to be disposed in the foam layer. Assembly grooves can be reserved during the foam layer forming process. The assembly groove is recessed along the thickness direction of the foam layer toward the inner bladder 120 and forms a gap with the inner bladder 120 . In other words, the assembly groove does not penetrate the foam layer, so that the oxygen treatment device 300 assembled to the assembly groove will not be close to the inner bladder 120 . That is, a certain thickness of heat insulation material is formed between the inner tank 120 and the oxygen treatment device 300 .

Using the above structure, by opening an assembly groove on the side of the foam layer facing away from the liner 120 that communicates with the external environment of the foam layer, and forming a gap between the assembly groove and the liner 120, the oxygen treatment device 300 can be The foam layer is formed and then installed into the assembly groove, which helps to simplify the difficulty of disassembly and assembly of the oxygen treatment device 300 . Moreover, since the oxygen treatment device 300 is not close to the inner tank 120, the solution of this embodiment can reduce or prevent the low-temperature environment of the refrigeration and freezing device 10 from affecting the normal progress of the electrochemical reaction. The oxygen treatment device 300 can be fixed in the assembly groove, and the fixing method includes but is not limited to screwing, snapping, riveting, welding, and bonding.

During the assembly process, there is no need to disassemble the back plate of the box shell 170, and the oxygen treatment device 300 can be directly fixed to the installation port through the installation opening. into the assembly groove. In a further example, a cover plate may be provided at the installation opening to cover the installation opening to improve the appearance. In another example, the oxygen treatment device 300 can be fixed into the assembly groove 182 first, and then the back plate of the box shell 170 is covered on the back of the foam layer.

In one example, the box body 510 is disposed within the foam layer. By arranging the box body 510 of the liquid storage module 500 in the foam layer, and making the liquid storage space of the box body 510 communicate with the oxygen treatment device 300, the liquid stored in the box body 510 can be used to replenish the oxygen treatment device 300. Electrolyte, since the box 510 does not occupy the second storage compartment, the refrigeration and freezing device 10 can use the liquid storage module 500 to replenish the electrolyte to the oxygen treatment device 300 without affecting the volume ratio, so that the oxygen treatment device 300 sustainably regulates the oxygen content of the second storage space.

The box body 510 of the liquid storage module 500 can be disposed at any part of the foam layer, for example, it can be disposed on the side of the inner bladder 120 , or can be disposed on the top, bottom and back of the inner bladder 120 . For a French-style refrigerator or a T-type refrigerator, in one example, the box body 510 of the liquid storage module 500 may be disposed in the gap between the upper inner pot 120 and the lower inner pot 120 .

In some optional embodiments, the box body 100 also has a box shell, and the foam layer is formed between the box shell and the inner bladder 120 . The box cover is provided on the outside of the foam layer to sandwich the foam layer with the inner bladder 120 . In one example, the refrigeration and freezing device may include a refrigeration inner pot, a variable temperature inner pot, and a freezing inner pot. In a further example, the box body can be disposed in the foam layer outside the refrigerated inner bag.

Referring to FIG. 12 , the inner bladder 120 is provided with an opening-shaped interactive window 124 , and the foam layer has an installation groove communicating with the interactive window 124 for assembling the liquid storage module 500 . After the foam layer is formed, the liquid storage module 500 can be assembled into the installation groove, thereby being disposed in the foam layer. The installation groove can be reserved during the foam layer forming process. The installation groove is recessed in a direction away from the interaction window 124 along the thickness direction of the foam layer, and forms a gap with the box shell. In other words, the installation groove does not penetrate through the foam layer, so that the liquid storage module 500 assembled into the installation groove will not be close to the tank shell. That is, a certain thickness of heat insulation material is formed between the box shell and the oxygen treatment device 300 .

With the above structure, the liquid storage module 500 does not need to be pre-installed in the foaming layer to avoid the foaming process from adversely affecting the structure and performance of the liquid storage module 500, and the assembly process of the liquid storage module 500 can be done in the second storage room. Execution, with the advantages of simple assembly process.

By opening the interactive window 124 on the inner liner 120 and setting an installation groove communicating with the interactive window 124 in the foam layer, and forming a gap between the installation groove and the case shell, the liquid storage module 500 can be installed in the foam layer. After molding, it is installed into the installation groove, which helps to simplify the difficulty of disassembly and assembly of the liquid storage module 500 . Moreover, since the installation groove does not penetrate the foam layer, the solution of this embodiment can reduce or avoid the significant reduction in the thermal insulation performance of the refrigeration and freezing device 10 caused by installing the liquid storage module 500 in the foam layer.

The liquid storage module 500 can be fixed in the installation groove, and the fixing method includes but is not limited to screwing, snapping, riveting, welding, and bonding. In some optional embodiments, the box body 510 is provided with a liquid injection port 514 connected to the liquid storage space, and the liquid injection port 514 is exposed through the interactive window 124, thereby allowing external liquid to be injected into the liquid storage space. FIG. 13 is a schematic structural diagram of the liquid storage module of the refrigeration and freezing device shown in FIG. 11 .

For example, the liquid filling port 514 is disposed on the side wall of the box body 510 facing the second storage compartment, so as to be exposed through the interactive window 124 .

By opening an interactive window 124 on the inner tank 120 and connecting the liquid filling port 514 of the box body 510 to the second storage compartment through the interactive window 124, the interactive window 124 can be used as an operation window for the user to add liquid to the liquid storage space. Since the interactive window 124 can expose the liquid injection port 514, when the liquid storage volume of the liquid storage space is insufficient, external liquid can be injected into the liquid storage space through the liquid injection port 514. Therefore, the above solution of this embodiment can simplify the liquid storage module. The liquid replenishment method of 500 enables the liquid storage module 500 to replenish the electrolyte to the oxygen treatment device 300 continuously.

The box body 510 is provided with a cover 550, and the cover 550 is reciprocally disposed at the liquid filling port 514 to open or close the liquid filling port 514. When the cover 550 opens the liquid filling port 514, the liquid filling port 514 is allowed to be exposed. By providing the cover 550 on the box body 510 and using the cover 550 to open or close the liquid filling port 514, the liquid filling port 514 can be opened only when receiving external liquid, thereby reducing or preventing foreign matter from entering the liquid storage space. , to keep the liquid stored in the liquid storage space clean.

The cover 550 may be a push-type pop-up cover, which can rotate and pop up under pressure to at least partially extend into the second storage compartment through the interactive window 124 to open the liquid filling port 514 .

In one example, the bottom of the cover 550 may be connected to the box body 510 through a rotating shaft and be pivotably connected to the box body 510 . When the lid body 550 closes the liquid filling port 514, its outer surface is coplanar with the outer surface of the box body 510. At this time, the top of the lid body 550 can be connected to the box body 510 through the snap-in structure; when it is necessary to open the liquid filling port 514 , the top of the cover 550 can be pressed to separate the top of the cover 550 from the box 510. At this time, the cover 550 can rotate around the rotating axis and at least partially extend into the second storage compartment, thereby opening the liquid filling port 514. .

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 revealing the liquid storage volume of the box body 510 . The visible area 516 of this embodiment is exposed through the interactive window 124 . The visible area 516 extends longitudinally and is located below the liquid filling port 514 .
