The refrigeration and freezing device 10 may generally include a box body 100 and a rotating storage box 900 . 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 interior of the box 100 defines a first storage area 650 and a second storage area 680 . For example, the box 100 may include an inner bladder, and the inner side of the inner bladder may define a storage compartment. The first storage area 650 and the second storage area 680 may be respectively formed in the storage room. For another example, a storage container 600 may be provided in the storage room, and the first storage area 650 and the second storage area 680 may be formed in the storage container 600 .

The rotating storage box 900 has a plurality of storage compartments 910 . FIG. 3 is a schematic exploded view of the internal structure of the refrigeration and freezing device 10 shown in FIG. 2 . Each storage compartment 910 is used to store items respectively. Each storage compartment 910 defines a storage partition, and the storage partition is used to store items. And the rotating storage box 900 is rotatably arranged, so that the storage compartment 910 is switchably arranged in the first storage area 650 and the second storage area 680 .

When the rotary storage box 900 rotates, the position of each storage compartment 910 changes accordingly. For example, it can rotate from the first storage area 650 to the second storage area 680, or from the second storage area 680 to the third storage area. 650 for one storage area. Therefore, each storage compartment 910 can be flexibly switched between the first storage area 650 and the second storage area 680 . It should be noted that, in one example, in addition to the first storage area 650 and the second storage area 680, the interior of the box 100 may also define more storage areas, such as a third storage area and / Or a fourth storage area, etc., when the rotating storage box 900 is rotated, it can be rotated from one storage area to another storage area.

By arranging a rotating storage box 900 with a plurality of storage compartments 910 in the box 100 and allowing the rotating storage box 900 to be rotatably arranged, the storage compartments 910 are switchably arranged in the first storage area 650 and the second storage area 680. When a certain storage compartment 910 needs to be switched from the first storage area 650 to the second storage area 680, the storage compartment 910 only needs to be rotated from the first storage area 650. To the second storage area 680, there is no need to take out the storage compartment 910 during the entire process. Therefore, using the above solution of the present invention, items can be directly exchanged between different functional partitions to flexibly and skillfully switch the storage environment of items.

In some optional embodiments, the refrigeration and freezing device 10 further includes a storage container 600 and a partitioning mechanism 620 . Among them, the storage container 600 is provided in the box 100 . The partition mechanism 620 is disposed in the internal space of the storage container 600 and separates the internal space of the storage container 600 into a first storage area 650 and a second storage area 680 . And the partition mechanism 620 has an assembly area for the rotary storage box 900 to be rotatably assembled therein.

When the rotating storage box 900 is rotatably assembled in the assembly area, the rotating storage box 900 also closes the assembly area, so that the first storage area 650 and the second storage area 680 are not connected to each other.

By dividing the first storage area 650 and the second storage area 680 in the storage container 600 and rotating the rotating storage box 900 to switch the position of any storage compartment 910, it is possible to create a space in the same storage container 600.

In one example, the partition mechanism 620 is a partition structure with a board surface extending in the vertical direction, so that the first storage area 650 and the second storage area 680 are arranged side by side in the horizontal direction. Therefore, each storage compartment 910 of the rotary storage box 900 does not need to change the height when switching positions, which is beneficial to reducing the difficulty of operating each storage compartment 910 when switching positions.

The rotating storage box 900 may be cylindrical, with a rotation axis extending in a vertical direction, and the rotation axis of the rotating storage box 900 is coaxial with the central axis of the rotating storage box 900 and the central axis of the assembly area.

With the above structure, when the rotating storage box 900 rotates, the outline of the rotating storage box 900 remains consistent. Therefore, the rotating storage box 900 always closes the assembly area when rotating, and does not destroy the isolation state between the first storage area 650 and the second storage area 680 .

The partitioning mechanism 620 includes a first partition section 621 and a second partition section 622 which are spaced apart from each other and whose plates are arranged coplanarly. The space between the first partition section 621 and the second partition section 622 forms an assembly area. In one example, the height of the rotating storage box 900 is the same as the height of the first partition section 621 and the height of the second partition section 622 . The rotating storage box 900, the first partition section 621 and the second partition section 622 can respectively extend from the lower surface of the top wall of the storage container 600 to the upper surface of the bottom wall of the storage container 600 to separate the first storage box. The storage area 650 and the second storage area 680 are connected to each other, so that the first storage area 650 and the second storage area 680 are not connected to each other.

In a further example, the rotating storage box 900 includes a disc-shaped chassis and a hollow cylindrical barrel 930 extending upward from an edge of the chassis, thereby defining the hollow cylindrical rotating storage box 900 .

A plurality of storage compartments 910 are formed in the cylinder 930, and the projections of the plurality of storage compartments 910 in a horizontal plane are centrally symmetrical with respect to the center of the chassis.

By arranging multiple storage compartments 910 in the cylinder 930 and making the projection of the multiple storage compartments 910 in the horizontal plane centrally symmetrical with respect to the center of the chassis, the multiple storage compartments 910 can be arranged inside the cylinder 930 Evenly distributed, when switching the position of a certain storage partition, the rotation angle of the rotating storage box 900 can be pre-calculated according to the current position of the storage partition, and then the rotating storage box 900 can be controlled according to the calculated rotation angle, so that The rotation process is controllable.

In some optional embodiments, the rotating storage box 900 further includes a central rotating shaft 940 and a plurality of partition boards.

The central rotating shaft 940 extends upward from the center of the chassis. The plate surface of each partition board extends in the vertical direction, and extends radially outward from the outer surface of the central rotating shaft 940 to the inner surface of the barrel 930, so as to space out a plurality of top openings inside the barrel 930. Storage compartment 910. A boundary is defined between every two adjacent partition boards A storage partition.

With the above structure, each storage partition can switch positions accordingly as the rotating storage box 900 rotates, and the rotation pace of each storage partition remains consistent.

In some optional embodiments, the first storage area 650 has a vent 610 for introducing external air to adjust the internal atmosphere using external air. For example, the vent 610 of the first storage area 650 can be connected to its external environment through a pipeline and receive gas from its external environment, such as oxygen-rich gas, oxygen-poor gas, or other gases, so that the first storage area 650 Create a high-oxygen fresh-keeping atmosphere, a low-oxygen fresh-keeping atmosphere or other controlled atmosphere atmosphere inside.

Each storage compartment 910 is provided with a ventilation opening to allow external air to enter the storage area through the ventilation opening when switching to the first storage area 650 . In one example, the top opening of each storage compartment 910 serves as a ventilation opening of the storage compartment 910 . In another example, the barrel 930 may be provided with openings or air holes as ventilation ports.

With the above structure, since the first storage area 650 can use external air to adjust the internal atmosphere, and the storage compartment 910 is provided with a ventilation port that allows external air to enter the storage partition, therefore, when a certain storage partition is switched to the third storage area, When a storage area 650 is provided, the storage atmosphere of the storage area and the first storage area 650 can be kept consistent.

In an optional embodiment, the first storage area 650 is provided on the rear side of the second storage area 680 . The storage container 600 is pullably disposed in the box 100 . FIG. 4 is another schematic exploded view of the internal structure of the refrigeration and freezing device 10 shown in FIG. 2 . The back wall of the storage container 600 is provided with a vent 610 connected to the first storage area 650 . For example, the storage container 600 may be pullably disposed on the base. The base is pullably installed in the storage room.

In one example, the storage container 600 is further provided with a first sealing cover 660 and a second sealing cover 690 .

Each sealing cover is respectively provided with a grab handle for the user to grab, thereby opening the first storage area 650 or the second storage area 680 .

The number of storage containers 600 may be at least one, and the number thereof may be set according to actual needs. When there are multiple storage containers 600, different types of food can be stored separately to avoid odor mixing or mutual contamination.

In a further embodiment, the refrigeration and freezing device 10 may further include a driving mechanism including a motor. The output shaft of the motor is drivingly connected to the central rotating shaft of the rotating storage box 900, and is used to drive the central rotating shaft of the rotating storage box 900 to rotate, thereby driving the entire rotating storage box 900 to rotate.

In another example, the output shaft of the motor may be transmission-connected to the chassis of the rotating storage box 900 for driving the chassis of the rotating storage box 900 to rotate, thereby driving the entire rotating storage box 900 to rotate.

In another example, the refrigeration and freezing device 10 may not be provided with a driving mechanism. In this case, the user can manually drive the rotating storage box 900 to rotate.

The refrigeration and freezing device 10 further includes a gas circuit assembly, which has a ventilation pipe 820 that communicates with the ventilation port 610 and is used to transport gas to the first storage area 650 . The ventilation pipe 820 is fixed on the rear side of the storage container 600 . And the ventilation pipe 820 and the ventilation port 610 are nested with each other and can be detachably arranged during the pulling process of the 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 in and detachable from each other during the pulling process of the storage container 600, in the storage room, Object container 600 is extracted At this time, since the vent 610 moves synchronously with the storage container 600, the vent pipe 820 and the vent 610 are disengaged and separated from each other. When the storage container 600 is reset, the vent pipe 820 and the vent 610 are Can be restored to a nested state and thus connected to each other. Using the above solution of this embodiment, the 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 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 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 When withdrawing, since the vent 610 moves synchronously with the storage container 600, the vent 610 comes out of the hollow cylindrical interface to achieve disengagement. When the storage container 600 is reset, the vent 610 can be inserted into the hollow cylindrical interface again. within to achieve nesting. Using the above solution of this embodiment, it is possible to ensure airtight connection between the 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, which is fixed in the storage compartment. For example, the mounting bracket 850 may be fixedly connected to the inner wall of the storage compartment. 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 storage room, 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 . Among them, the main body part 851 is fixed in the storage compartment, and defines a concave arc-shaped plate that is concave downward and arc-shaped; 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 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.

In one example, the vent 610 is located on the back wall of the storage container 600 . For example, the body portion 851 can be disposed in close contact with the back wall of the storage container 600 .

The mounting bracket 850 also includes a bending portion 854, which is formed by bending forward or backward from the end of the body portion 851, and is disposed in close contact with the side wall of the storage compartment. The bent portion 854 is provided with a third threaded hole for passing the screw Then the bent portion 854 is fixedly assembled to the side wall of the storage compartment.

When the vent 610 is opened on the back wall of the storage container 600, the body part 851 is fixed to the rear side of the storage container 600, and the bending part 854 bent forward is connected to the end of the body part 851, Since the bending portion 851 can be fixedly connected to the side wall of the storage compartment through screwing, based on the above structure, on the one hand, the mounting bracket 850 of the air path assembly can be stably assembled in the storage compartment to fix it. The joint between the air conditioning pipeline 440 and the vent 610 can, on the other hand, fix the body part 851 at any position away from the back wall of the storage compartment, so that there is a gap between the body part 851 and the back wall of the storage compartment. Leave enough space for piping.

The vent 610 is in the shape of a hollow column, and it bulges outward from the back wall of the 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.

When the vent 610 is hollow cylindrical and bulges outward from the back wall of the storage container 600, the first end of the vent pipe 820 is set as a hollow cylindrical interface for the vent 610 to be nested in the storage container. When 600 is withdrawn, since the vent 610 moves synchronously with the storage container 600, the vent 610 comes out of the hollow cylindrical interface to achieve disengagement. When the storage container 600 is reset, the vent 610 can be inserted into the hollow cylinder again. within the interface to achieve nesting. Using the above solution of this embodiment, it is possible to ensure airtight connection between the storage container 600 and the ventilation pipe 820, thereby improving the air conditioning efficiency.

In some optional embodiments, the second end 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 of the ventilation pipeline 820 and is used to transport gas.

FIG. 5 is a schematic structural diagram of the transfer pipeline 810 of the refrigeration and freezing device 10 shown in FIG. 4 . FIG. 6 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. Storage spaces are generally cooler. Since the transfer pipeline 810 is directly connected to the ventilation port 610 of the storage container 600 via the ventilation pipeline 820 and is close to the storage space, when the temperature of the storage space is low, the temperature of the transfer pipeline 810 is also low. 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 temperature of the storage space is When the temperature is low, the moisture carried by the gas is not easily retained 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, so as to achieve sustainable gas exchange between the storage space and its external environment. This enables the 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.

For example, the first end of the air conditioning pipeline 440 can be directly connected to the switching pipeline 810 , and the second end can be directly connected to the exhaust hole 323 .

Using the above structure, the multiple storage compartments 910 of the rotating storage box 900 can be switched back and forth between the high-oxygen fresh-keeping area and the non-high-oxygen fresh-keeping area. When the air conditioning pipeline 440 is used to transport oxygen from the electrochemical reaction chamber to the first storage area 650, the first storage area 650 can create a high-oxygen preservation environment. When the storage area 650 is switched to the second storage area 680, the storage compartment can be switched from the high oxygen preservation area to the non-high oxygen preservation area. When a certain storage compartment 910 is switched from the second storage area 680 to the first storage area, When the storage area is 650, the storage compartment 910 can be switched from a non-high oxygen preservation area to a high oxygen preservation area. Therefore, using the above solution of this embodiment, different storage partitions of the refrigeration and freezing device 10 can be divided into a high oxygen preservation area and a non-high oxygen preservation area. Switch back and forth between oxygen preservation zones.

Under the action of the air circuit assembly, air flow communication can be achieved between the air conditioning pipeline 440 and the ventilation port 610 through the transfer pipeline 810 and the ventilation pipeline 820 . The transfer pipe 810 and the vent pipe 820 are used to cleverly connect the air conditioning pipe 440 and the vent 610. There is no need to directly seal the connection between the port of the air conditioning pipe 440 and the vent 610, which is conducive to simplifying refrigeration and freezing.

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

In one example, the refrigeration and freezing device 10 may include an inner bladder 120 and an inner bladder 150 . In the above embodiments, the storage container 600 may be disposed inside the inner bladder 150 . The inner bladder 150 may define a temperature-changing compartment 152 or a freezing compartment 152 . The inner bladder 120 defines another storage compartment, such as a refrigeration compartment, and the storage compartment may define another storage space 122. For convenience of distinction, this storage space may be named a second storage space. The cathode plate of the oxygen treatment device 300 is in gas flow communication with the storage space 122, thereby reducing the oxygen content in the storage space through an electrochemical reaction.

In one example, the oxygen treatment device 300 may be disposed within the foam layer. Figure 9 is a schematic structural diagram of a refrigeration and freezing device according to an embodiment of the present invention. Figure 10 is a schematic internal structural diagram of the refrigeration and freezing device shown in Figure 9. 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 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 pipe 210 and the air return pipe 220 are used to connect the storage space 122 and the oxygen treatment device 300. The gas with a high oxygen content in the storage space 122 can flow to the cathode plate 330 through the air inlet pipe 210.

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 .

For example, a support plate for fixing the compressor is provided at the bottom of the compressor chamber, and the oxygen treatment device 300 can be directly or indirectly disposed on the support plate.

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.

The electrolyte is replenished to the oxygen treatment device 300 so that the oxygen treatment device 300 can continuously adjust the oxygen content of the storage space 122 .

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-shaped 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 150 .

In some optional embodiments, the box body 100 also has a box shell 170, and a foam layer is formed between the box shell 170 and the inner bladder. The box shell 170 is covered on the outside of the foam layer to sandwich the foam layer with the inner container. 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.

The liner 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 170 . In other words, the mounting groove does not penetrate the foam layer, so that the liquid storage module 500 assembled into the mounting groove will not be tightly attached to the tank shell 170 . That is, a certain thickness of heat insulation material is formed between the box shell 170 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 prevent 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 performed in the storage space 122 , with the advantages of simple assembly process.

By opening the interactive window 124 on the inner liner 120, and providing a mounting groove communicating with the interactive window 124 in the foam layer, and forming a gap between the mounting groove and the case shell 170, the liquid storage module 500 can be foamed. The layer is formed and then 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 obvious 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.

FIG. 13 is a schematic perspective view of the liquid storage module of the refrigeration and freezing device shown in FIG. 12 . For example, the liquid filling port 514 is disposed on the side wall of the box body 510 facing the storage space 122 so as to be exposed through the interactive window 124 .

By opening an interactive window 124 on the inner tank 150 and connecting the liquid filling port 514 of the box 510 to the storage space 122 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. 500 The liquid replenishment method 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.

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 that can rotate and pop up under pressure to at least partially extend into the storage space 122 through the interaction 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 storage space 122, thereby opening the liquid filling port 514.

After understanding the embodiments of the present disclosure, those skilled in the art should easily understand the assembly structure between the push-type spring cover and the box body 510 , which will not be described in detail in this disclosure.

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 . For example, the visible area 516 is also provided on the side wall of the box 510 facing the storage space 122 so as to be exposed through the interactive window 124 .

By arranging the visible area 516 on the box body 510 and making the visible area 516 opposite to the interactive window 124, the interactive window 124 can be used as an observation window for the user to observe the liquid level in the liquid storage space. Since the interactive window 124 can reveal the visible area 516, the user can easily observe the liquid storage volume in the liquid storage space. Therefore, the above solution of this embodiment can enable the user to obtain an intuitive interactive experience. When the liquid storage volume in the liquid storage space is insufficient, the user can take rehydration measures in a timely manner.

In one example, the interactive window 124 may be located on the side wall of the inner bladder 150 , and the mounting groove is correspondingly disposed between the side wall of the inner bladder 150 and the side wall of the box shell 170 .

Since the side wall of the inner tank 150 is not easily blocked by the items stored in the storage space 122 and is close to the user's movable area, an interactive window 124 is provided on the side wall of the inner tank 150 to allow the liquid to be stored. The module 500 is embedded in the foam layer on the side of the box 100, which can reduce the difficulty of interaction between the user and the liquid storage module 500 to a certain extent. The user can quickly obtain the stored liquid without moving the items stored in the storage space 122. The liquid storage capacity information of the module 500 is stored, and the liquid replenishment operation can be performed in time when the liquid storage capacity of the liquid storage module 500 is insufficient.

In some optional embodiments, the liquid storage module 500 may further include a liquid level sensor, which is disposed in the liquid storage space and used to detect the liquid level in the liquid storage space. When the liquid level sensor detects that the liquid level in the liquid storage space is lower than the set value, the refrigeration and freezing device 10 can send out an alarm signal. For example, the alarm signal can be transmitted to the user through wireless transmission technology to remind the user to replenish liquid in time.

In some further examples, the box body 510 has a first side wall flush with the side wall of the inner bladder 150 and closing the interaction window 124 and a second side wall opposite the first side wall and hidden inside the mounting groove. . The liquid filling port 514 is located on the first side wall. The opening area of the interactive window 124 and the surface area of the first side wall of the box body 510 can be approximately the same, so that the first side wall of the box body 510 just closes the interactive window 124 and the outer surface of the first side wall is in contact with the side wall of the inner bladder 150 The inner surfaces are connected into a complete plane to make the appearance beautiful.

The liquid filling port 514 may be provided in the upper section of the first side wall. The visible area 516 can also be provided on the first side wall, for example, it can be provided on the middle section or the lower section of the first side wall.

A liquid outlet 511 is provided on the bottom wall, and the liquid outlet 511 is connected to the liquid replenishing port 322 to replenish electrolyte to the electrochemical reaction chamber.

In some optional embodiments, the box body 510 further has third side walls and fourth side walls connected between the first side wall and the second side wall and arranged oppositely in the horizontal direction. A fixing piece 517 is connected to the outer surface of the third side wall and/or the fourth side wall, and the fixing piece 517 has a screw hole for cooperating with a screw to fix the box body 510 to the mounting groove.

The liquid outlet 511 is higher than the liquid replenishing port 322. In this way, the liquid in the liquid storage space can automatically flow into the electrochemical reaction chamber under the action of gravity without the need for a power device.

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

In some further examples, a one-way valve may be provided on the fluid replacement pipeline 420 to allow one-way passage of liquid from the liquid outlet 511 to ensure one-way flow of liquid flowing through the fluid replacement pipeline 420 .

The refrigeration and freezing device 10 also includes a filter pipeline 430 embedded in the foam layer. The first end of the filter pipeline 430 is connected to the exhaust hole 323 of the oxygen treatment device 300 , and the second end of the filter pipeline 430 is connected to the box 510 The air inlet 512 is used to guide the oxygen flowing out from the exhaust hole 323 to the air outlet 513, so as to enter the liquid storage space for filtration.

The liquid storage module 500 may further include an air filter pipe 540 and an air outlet pipe. Among them, the air filter pipe 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 air outlet pipe is inserted into the box body 510 from the air outlet 513, and extends to the upper section of the liquid storage space, and is located above the liquid stored in the liquid storage space, so as to guide the filtered oxygen out through it.

Using the above solution, the oxygen to be filtered can reach the liquid storage space under the guidance of the air filter 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, completing the purification of the gas. The purified gas can flow into the designated space under the guidance of the air outlet pipe, thereby regulating the oxygen in the space. The role of content.

In an optional embodiment, the liquid storage module 500 further includes an air blocking mechanism 530, which is disposed in the liquid storage space and separates the liquid storage space into a gas filter area and a non-gas filter area where the air path is blocked. The gas filter area is used to allow the gas flowing into the air inlet 512 to flow therethrough to achieve filtration. The non-filtered area is used to receive liquid from the outside.

The air filter area and the non-air filter area can be arranged side by side in the transverse direction. The air blocking mechanism 530 blocks a part of the liquid path between the air filter area and the non-air filter area, so that the air filter area and the non-air filter area can be blocked when the air path is blocked. Keep the fluid path connected. For example, the air blocking mechanism 530 is a partition-like structure located between the air filter area and the non-air filter area and extends downward from the lower surface of the top wall of the box body 510 and forms a gap with the upper surface of the bottom wall of the box body 510 . The air filtering area is located on one lateral side of the air blocking mechanism 530 , and the non-air filtering area is located on the other lateral side of the air blocking mechanism 530 . The air inlet 512 and the air outlet 513 can be respectively provided on the top wall of the area where the air filter area is located. The liquid injection port 514 can be provided on the top wall of the area where the non-air filter area is located.

Using the above structure, by arranging the air blocking mechanism 530 in the liquid storage space, and using the air blocking mechanism 530 to separate the liquid storage space into a filtered air area and a non-air filtered area where the air path is blocked, it is possible to execute the operation only in the air filtered area. Gas purification function. Since the air filter area is only a subspace of the liquid storage space and is blocked from other areas of the liquid storage space, the gas flowing into the air inlet 512 can only flow in the air filter area without The liquid storage module 500 of this embodiment has a high purification gas release rate due to free diffusion into the non-filtered gas area, resulting in the inability to discharge quickly.
