Description

Technical Field

[0001] This invention relates to modified atmosphere storage technology, and in particular to refrigeration and freezing equipment. Background Technology

[0002] Refrigeration and freezing units with different functional zones are widely favored by consumers. Because different functional zones have different preservation atmospheres, they can be used to store different items.

[0003] The inventors recognized that in existing refrigeration and freezing devices, items cannot be directly exchanged between different functional zones. When it is necessary to move an item from one functional zone to another, the user must first take the item out of the original functional zone and then put it into the other functional zone, which is a very complicated process.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to overcome at least one technical defect in the prior art and to provide a refrigeration and freezing apparatus.

[0006] A further object of the present invention is to provide a refrigeration and freezing device that allows for direct exchange of items between different functional zones, thereby flexibly and cleverly switching the storage environment of items.

[0007] Another further object of the present invention is to enable different storage zones of the refrigeration and freezing apparatus to switch back and forth between a high-oxygen preservation zone and a non-high-oxygen preservation zone.

[0008] In particular, the present invention provides a refrigeration and freezing apparatus, comprising:

[0009] The box, whose interior defines a first storage area and a second storage area; and

[0010] A rotating storage box has multiple storage compartments, each compartment defining a storage area; and the rotating storage box is rotatably configured so that the storage compartments can be switched between the first storage area and the second storage area.

[0011] Optionally, the refrigeration and freezing unit also includes:

[0012] Storage containers are disposed within the box; and

[0013] A partition mechanism is provided in the internal space of the storage container to divide the internal space of the storage container into a first storage area and a second storage area; and the partition mechanism has an assembly area in which the rotating storage box can be rotatably assembled.

[0014] Optionally, the partition mechanism is a partition structure with the plate surface extending vertically, such that the first storage area and the second storage area are arranged side by side in the horizontal direction; and

[0015] The rotating storage box is cylindrical, with its rotation axis extending vertically, and the rotation axis of the rotating storage box is coaxial with the central axis of the rotating storage box and the central axis of the assembly area.

[0016] Optionally, the partition mechanism includes a first partition section and a second partition section that are spaced apart from each other and have coplanar surfaces; and the gap between the first partition section and the second partition section forms the assembly area.

[0017] Optionally, the rotating storage box includes a disc-shaped base and a hollow cylindrical body extending upward from the edge of the base; and

[0018] Multiple storage compartments are formed inside the cylinder, and the projections of the multiple storage compartments in the horizontal plane are centrally symmetrical with respect to the center of the chassis.

[0019] Optionally, the rotating storage box further includes:

[0020] A central pivot shaft extends upward from the center of the chassis; and

[0021] Multiple partitions, each of which extends vertically and radially outward from the outer surface of the central pivot to the inner surface of the cylinder, thereby creating multiple storage compartments with top openings inside the cylinder; each storage partition is defined between every two adjacent partitions.

[0022] Optionally, the first storage area has a vent for introducing external gas to regulate the internal atmosphere using the external gas; and

[0023] Each of the storage compartments is provided with a ventilation port to allow external gas to enter the storage compartment through the ventilation port when switching to the first storage area.

[0024] Optionally, the first storage area is located behind the second storage area; the storage container is removably mounted inside the box; the back wall of the storage container has a vent communicating with the first storage area; and

[0025] The refrigeration and freezing device further includes a gas circuit assembly having a vent pipe that connects to the vent and is used to deliver gas to the first storage area. The vent pipe is fixed to the rear side of the storage container. The vent pipe and the vent are nested together and detachably arranged during the pulling and pulling of the storage container.

[0026] Optionally, the vent is a hollow cylindrical shape and protrudes outward from the back wall of the storage container; one end of the vent pipe has a hollow cylindrical interface into which the vent is nested.

[0027] Optionally, the refrigeration and freezing unit also includes:

[0028] An oxygen treatment device is disposed within the chamber and includes a housing and an electrode pair. The housing defines an electrochemical reaction chamber for holding an electrolyte. The electrode pair is disposed within the electrochemical reaction chamber and is used to transfer external oxygen into the electrochemical reaction chamber via an electrochemical reaction. The housing has an exhaust port communicating with the electrochemical reaction chamber for discharging oxygen from the chamber.

[0029] The controlled atmosphere pipeline has a first end for connecting to the ventilation pipeline and a second end for connecting to the exhaust port.

[0030] The refrigeration and freezing device of the present invention, by setting a rotating storage box with multiple storage compartments inside the box, and rotatably setting the rotating storage box so that the storage compartments can be switched between the first storage area and the second storage area, when it is necessary to switch a storage compartment from the first storage area to the second storage area, it is only necessary to rotate the storage compartment from the first storage area to the second storage area. The entire process does not require taking out the storage compartment. Therefore, by adopting the above solution of the present invention, items can be directly exchanged between different functional areas, so as to flexibly and cleverly switch the storage environment of items.

[0031] Furthermore, in the refrigeration and freezing apparatus of the present invention, when oxygen from the electrochemical reaction chamber is delivered to the first storage area via a controlled atmosphere pipeline, a high-oxygen preservation environment can be created in the first storage area. When a storage compartment is switched from the first storage area to the second storage area, the storage compartment can be switched from a high-oxygen preservation area to a non-high-oxygen preservation area. When a storage compartment is switched from the second storage area to the first storage area, the storage compartment can be switched from a non-high-oxygen preservation area to a high-oxygen preservation area. Therefore, by adopting the above-mentioned solution of the present invention, different storage zones of the refrigeration and freezing apparatus can be switched back and forth between high-oxygen preservation areas and non-high-oxygen preservation areas.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0051] This invention provides a refrigeration and freezing device 10. Figure 1This is a schematic structural diagram of a refrigeration and freezing apparatus 10 according to an embodiment of the present invention. Figure 2 This is a schematic internal structural diagram of a refrigeration and freezing device 10 according to an embodiment of the present invention. The refrigeration and freezing device 10 generally includes a cabinet 100 and a rotating storage box 900. The refrigeration and freezing device 10 of the present invention can be a refrigerator, or a freezer, freezer cabinet, or other refrigeration equipment with low-temperature storage function.

[0052] The interior of the housing 100 defines a first storage area 650 and a second storage area 680. For example, the housing 100 may include an inner liner, the inside of which may define a storage compartment. The first storage area 650 and the second storage area 680 may be formed within the storage compartment. Alternatively, a storage container 600 may be provided within the storage compartment, and the first storage area 650 and the second storage area 680 may be formed within the storage container 600.

[0053] The rotating storage box 900 has multiple storage compartments 910. Figure 3 yes Figure 2 The diagram shows an exploded schematic view of the internal structure of the refrigeration and freezing device 10. Each storage compartment 910 is used for storing items. Each storage compartment 910 defines a storage zone for storing items. The rotating storage box 900 is rotatably configured so that the storage compartment 910 can be switched between the first storage zone 650 and the second storage zone 680.

[0054] As the rotating storage box 900 rotates, the positions of each storage compartment 910 change accordingly. For example, it can rotate from the first storage area 650 to the second storage area 680, or vice versa. Thus, each storage compartment 910 can flexibly switch 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 and second storage areas 650 and 680, the interior of the box 100 can also define more storage areas, such as a third and / or fourth storage area, etc., which can be moved from one storage area to another when the rotating storage box 900 rotates.

[0055] By providing a rotating storage box 900 with multiple storage compartments 910 inside the housing 100, and rotatably setting the rotating storage box 900, the storage compartments 910 can be switched between the first storage area 650 and the second storage area 680. When it is necessary to switch a storage compartment 910 from the first storage area 650 to the second storage area 680, it is only necessary to rotate the storage compartment 910 from the first storage area 650 to the second storage area 680. The entire process does not require removing the storage compartment 910. Therefore, by adopting the above solution of the present invention, items can be directly exchanged between different functional areas, so as to flexibly and cleverly switch the storage environment of items.

[0056] In some optional embodiments, the refrigeration and freezing apparatus 10 further includes a storage container 600 and a dividing mechanism 620. The storage container 600 is disposed within the housing 100. The dividing mechanism 620 is disposed within the internal space of the storage container 600, dividing the internal space of the storage container 600 into a first storage area 650 and a second storage area 680. The dividing mechanism 620 also has an assembly area for a rotating storage box 900 to be rotatably assembled therein.

[0057] When the rotating storage box 900 is rotatably mounted 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.

[0058] The storage container 600 is divided into a first storage area 650 and a second storage area 680, and the rotating storage box 900 can switch the position of any storage compartment 910 by rotating it. This can create multiple different storage atmospheres in the same storage container 600 and enable the storage container 600 to have an adjustable storage atmosphere.

[0059] In one example, the partition mechanism 620 is a partition structure with the panel extending vertically, so that the first storage area 650 and the second storage area 680 are arranged side by side in the horizontal direction. As a result, the individual storage compartments 910 of the rotating storage box 900 do not need to change height when switching positions, which helps to reduce the difficulty of switching positions of the individual storage compartments 910.

[0060] The rotating storage box 900 can be cylindrical, with its rotation axis extending vertically, 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.

[0061] With the above structure, the outer contour of the rotating storage box 900 remains constant as it rotates. Therefore, the rotating storage box 900 always closes the assembly area during rotation and does not disrupt the partition between the first storage area 650 and the second storage area 680.

[0062] The partition mechanism 620 includes a first partition section 621 and a second partition section 622 that are spaced apart from each other and have coplanar surfaces. The gap 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 second partition section 622. The rotating storage box 900, the first partition section 621, and the second partition section 622 can 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, respectively, to separate the first storage area 650 and the second storage area 680, so that the first storage area 650 and the second storage area 680 are not connected to each other.

[0063] In a further example, the rotating storage box 900 includes a disc-shaped base and a hollow cylindrical body 930 extending upward from the edge of the base, thereby defining a hollow cylindrical rotating storage box 900.

[0064] Multiple storage compartments 910 are formed inside the cylinder 930, and the projections of the multiple storage compartments 910 in the horizontal plane are centrally symmetrical with respect to the center of the chassis.

[0065] By setting multiple storage compartments 910 inside the cylinder 930 and making the projections 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 evenly distributed inside the cylinder 930. When switching the position of a certain storage compartment, the rotation angle of the rotating storage box 900 can be pre-calculated based on the current position of the storage compartment, and then the rotating storage box 900 can be controlled according to the calculated rotation angle, so that the rotation process is controllable.

[0066] In some alternative embodiments, the rotating storage box 900 also includes a central pivot 940 and multiple partitions.

[0067] The central pivot 940 extends upward from the center of the chassis. Each partition plate extends vertically and radially outward from the outer surface of the central pivot 940 to the inner surface of the cylinder 930, thereby creating multiple storage compartments 910 with top openings inside the cylinder 930. A storage compartment is defined between each pair of adjacent partition plates.

[0068] With the above structure, each storage compartment can switch positions accordingly as the rotating storage box 900 rotates, and the rotation pace of each storage compartment remains consistent.

[0069] In some alternative embodiments, the first storage area 650 has a vent 610 for introducing external gas to regulate the internal atmosphere. For example, the vent 610 of the first storage area 650 can be connected to its external environment through a pipe and receive gas from its external environment, such as oxygen-enriched gas, oxygen-deficient gas, or other gases, thereby creating a high-oxygen preservation atmosphere, a low-oxygen preservation atmosphere, or other modified atmosphere inside the first storage area 650.

[0070] Each storage compartment 910 is provided with a ventilation port to allow external gas to enter the storage compartment when switching to the first storage area 650. In one example, the top opening of each storage compartment 910 serves as the ventilation port. In another example, the cylinder 930 may have an opening or vent as a ventilation port.

[0071] With the above structure, since the first storage area 650 can use external gas to regulate the internal atmosphere, and the storage compartment 910 is provided with an air exchange port that allows external gas to enter the storage compartment, when a certain storage compartment is switched to the first storage area 650, the storage atmosphere of that storage compartment can be kept consistent with that of the first storage area 650.

[0072] In an optional embodiment, the first storage area 650 is located behind the second storage area 680. The storage container 600 is removably disposed within the housing 100. Figure 4 yes Figure 2 Another schematic exploded view of the internal structure of the refrigeration and freezing apparatus 10 shown. The back wall of the storage container 600 has a vent 610 communicating with the first storage area 650. For example, the storage container 600 can be removably mounted on a base. This base is removably mounted within the storage compartment.

[0073] In one example, the storage container 600 is further provided with a first sealing cap 660 and a second sealing cap 690. The first sealing cap 660 is used to seal the first storage area 650, and the second sealing cap 690 is used to seal the second storage area 680. Each sealing cap is provided with a handle for a user to grasp, thereby opening the first storage area 650 or the second storage area 680.

[0074] The number of storage containers 600 can be at least one, and the number can be set according to actual needs. When there are multiple storage containers 600, different types of food can be stored separately to avoid cross-contamination or mixing of flavors.

[0075] In a further embodiment, the refrigeration and freezing apparatus 10 may further include a drive mechanism, which includes a motor. The output shaft of the motor is connected to the central rotating shaft of the rotating storage box 900 for driving the central rotating shaft of the rotating storage box 900 to rotate, thereby driving the entire rotating storage box 900 to rotate.

[0076] In another example, the output shaft of the motor can be connected to the chassis of the rotating storage box 900 to drive the chassis of the rotating storage box 900 to rotate, thereby driving the entire rotating storage box 900 to rotate.

[0077] In another example, the refrigeration and freezing unit 10 may also be without a drive mechanism, in which case the rotating storage box 900 can be manually driven by the user.

[0078] The refrigeration and freezing device 10 also includes a gas passage assembly having a vent pipe 820 that connects to the vent 610 and is used to supply gas to the first storage area 650. The vent pipe 820 is fixed to the rear side of the storage container 600. The vent pipe 820 and the vent 610 are nested together and detachable during the pulling and pulling of the storage container 600.

[0079] By arranging an air circuit assembly inside the storage compartment, and ensuring that the vent pipe 820 and vent 610 of the air circuit assembly are nested and detachable during the pulling and unrolling of the storage container 600, when the storage container 600 is pulled out, the vent 610 moves synchronously with the storage container 600, thus detaching and separating from each other. When the storage container 600 is reset, the vent pipe 820 and vent 610 can return to their nested state, thereby connecting to each other. Using the above-described solution of this embodiment, the storage container 600 can receive external gas while being pullable to regulate the internal atmosphere.

[0080] In some alternative embodiments, the vent 610 is a hollow cylindrical shape and bulges outward from the back wall of the storage container 600. One end of the venting conduit 820 has a hollow cylindrical interface into which the vent 610 is nested.

[0081] When the vent 610 is a hollow cylindrical shape and protrudes outward from the back wall of the storage container 600, one end of the vent pipe 820 is configured as a hollow cylindrical interface into which the vent 610 can be nested. When the storage container 600 is pulled out, the vent 610 moves synchronously with the storage container 600, thus disengaging from the hollow cylindrical interface to achieve de-embedding. When the storage container 600 is reset, the vent 610 can be reinserted into the hollow cylindrical interface to achieve nesting. Using the above-described scheme of this embodiment, an airtight connection can be ensured between the storage container 600 and the vent pipe 820, thereby improving the controlled atmosphere efficiency.

[0082] In some alternative embodiments, the pneumatic assembly also includes a mounting bracket 850, which is fixed to the storage compartment interior. For example, the mounting bracket 850 may be fixedly connected to the inner wall of the storage compartment. The fixing method includes, but is not limited to, screwing, snap-fitting, welding, and riveting.

[0083] The mounting bracket 850 has a hollow cylindrical channel into which the venting pipe 820 is inserted for fixed assembly. In other words, the venting pipe 820 is fixedly connected to the mounting bracket 850 for fixation.

[0084] 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 interior wall of the storage room, which improves the positional flexibility of the ventilation pipe 820.

[0085] In some alternative embodiments, the mounting bracket 850 includes a body portion 851 and a cover portion 852. The body portion 851 is fixed to the storage compartment and defines a downwardly recessed, arc-shaped plate; the concave arc-shaped plate serves as the lower channel wall of the hollow cylindrical channel.

[0086] The cover portion 852 defines an upwardly recessed, arc-shaped plate, which serves as the upper channel wall of the hollow cylindrical channel. The upper channel wall and the lower channel wall together form a fixing portion.

[0087] The main body 851 and the cover 852 are detachable and independently designed, not integrally formed. The main body 851 and the cover 852 together define a hollow cylindrical channel for accommodating the vent pipe 820. Since the main body 851 and the cover 852 are detachable and independently designed, when assembling the vent pipe 820, the vent pipe 820 can be first placed on the concave arc-shaped plate of the main body 851, and then the cover 852 can be fixed to the main body 851. This ensures that the vent pipe 820 is securely assembled within the hollow cylindrical channel. Furthermore, when it is necessary to disassemble the vent pipe 820, the main body 851 and the cover 852 can be separated, making the disassembly process simple.

[0088] The cover portion 852 is detachably mounted on top of the body portion 851. The cover portion 852 also defines first threaded holes located on both sides of the upper channel wall. The body portion 851 is correspondingly formed with second threaded holes located on both sides of the lower channel wall and corresponding to the first threaded holes, so as to achieve detachable assembly by screwing.

[0089] In one example, the vent 610 is located on the back wall of the storage container 600. For example, the body portion 851 may be disposed abutting against the back wall of the storage container 600.

[0090] The mounting bracket 850 also includes a bending portion 854, which is formed by bending forward or backward from the end of the main body 851 and is disposed against the side wall of the storage compartment. The bending portion 854 has a third threaded hole for fixing the bending portion 854 to the side wall of the storage compartment by screwing.

[0091] When a vent 610 is opened on the back wall of the storage container 600, and the main body 851 is fixed to the rear side of the storage container 600, and a forward-bent portion 854 is connected to the end of the main body 851, the bent portion 851 can be fixedly connected to the side wall of the storage compartment by screwing. Therefore, based on the above structure, on the one hand, the mounting bracket 850 of the air circuit assembly can be stably assembled in the storage compartment to fix the joint between the gas regulating pipe 440 and the vent 610. On the other hand, the main body 851 can be fixed at any position away from the back wall of the storage compartment, so that sufficient space is reserved between the main body 851 and the back wall of the storage compartment for arranging the pipe.

[0092] The vent 610 is a hollow cylindrical shape that bulges outward from the back wall of the storage container 600 and extends at least partially into the hollow cylindrical channel. The first end 821 of the venting conduit 820 defines a hollow cylindrical interface into which the vent 610 is nested.

[0093] When the vent 610 is a hollow cylindrical shape and protrudes outward from the back wall of the storage container 600, the first end of the vent pipe 820 is configured as a hollow cylindrical interface into which the vent 610 can be nested. When the storage container 600 is pulled out, the vent 610 moves synchronously with the storage container 600, thus disengaging from the hollow cylindrical interface to achieve de-embedding. When the storage container 600 is reset, the vent 610 can be reinserted into the hollow cylindrical interface to achieve nesting. Using the above-described scheme of this embodiment, an airtight connection can be ensured between the storage container 600 and the vent pipe 820, thereby improving the controlled atmosphere efficiency.

[0094] In some alternative embodiments, the second end of the venting conduit 820 has another hollow cylindrical interface. The refrigeration and freezing apparatus 10 also includes a transfer conduit 810 that connects to the second end of the venting conduit 820 and is used for conveying gas.

[0095] Figure 5 yes Figure 4 A schematic structural diagram of the transfer pipe 810 of the refrigeration and freezing device 10 shown. Figure 6 yes Figure 4A schematic perspective view of the transfer pipe 810 of the refrigeration and freezing apparatus 10 is shown. The interior of the transfer pipe 810 defines an airflow channel 813 that is inclined relative to the horizontal plane. The temperature of the storage space is generally low. Since the transfer pipe 810 is directly connected to the vent 610 of the storage container 600 via a vent pipe 820 and is close to the storage space, the temperature of the transfer pipe 810 is correspondingly low when the temperature of the storage space is low.

[0096] By tilting the airflow channel 813 of the transfer pipe 810 relative to the horizontal plane, the angle between the airflow channel 813 and the horizontal plane can form an acute angle or a right angle. When the gas flowing through the transfer pipe 810 contains moisture and the temperature of the storage space is low, the moisture carried by the gas is not easy to remain inside the airflow channel 813. This helps to reduce or avoid the blockage of the airflow channel 813 due to frost and dew, so that the storage space can achieve sustainable gas exchange with its external environment, and thus the storage space can maintain a low-temperature preservation atmosphere for a long time.

[0097] The transfer pipe 810 has a first interface 811 that connects to the controlled atmosphere pipe 440 and a second interface 812 that connects to the ventilation pipe 820, and the aforementioned airflow channel 813 is connected between the second interface 812 and the first interface 811, so that the controlled atmosphere pipe 440 connects to the ventilation port 610.

[0098] The first interface 811 and the second interface 812 are hollow cylindrical interfaces formed by outward bulging of the outer surface of the self-rotating pipe 810. The first interface 811 is nested with and detachably disposed from the second end of the controlled atmosphere pipe 440. The second interface 812 is nested with and detachably disposed from another hollow cylindrical interface.

[0099] The interiors of the first interface 811 and the second interface 812 respectively define hollow channels that connect to the airflow channel 813 and are inclined relative to the horizontal plane. That is, the hollow channels of the first interface 811 and the hollow channels of the second interface 812 are also inclined.

[0100] With the above structure, since the hollow channel of each interface is connected to the airflow channel 813, this is equivalent to extending the path of the inclined section of the transfer pipe 810, which can further reduce the risk of air blockage in the transfer pipe 810 and keep the gas regulating pipe 440 and the air inlet 610 unobstructed.

[0101] In some optional embodiments, the airflow channel 813 of the transfer pipe 810 includes a first channel section 813a and a second channel section 813b. The first channel section 813a connects to the hollow channel inside the first interface 811. The second channel section 813b connects to the first channel section 813a and also connects to the hollow channel inside the second interface 812.

[0102] The inclination of the second channel section 813b is different from that of the first channel section 813a. In other words, the angle between the second channel section 813b and the horizontal plane is different from that between the first channel section 813a and the horizontal plane. This will cause the liquid carried by the gas to have different flow velocities when flowing through the first channel section 813a and the second channel section 813b.

[0103] By arranging two channel sections with different inclinations in the transfer pipeline 810, the connection between each channel section and its corresponding interface can be simplified. On the other hand, since the gas flows at different velocities when passing through the first channel section 813a and the second channel section 813b, the above-mentioned solution in this embodiment can further reduce the risk of gas blockage in the airflow channel 813.

[0104] In some alternative embodiments, the angle between the first channel segment 813a and the horizontal plane is greater than the angle between the second channel segment 813b and the horizontal plane.

[0105] Using the above scheme, when the gas regulating pipeline 440 delivers gas to the storage space, even if the liquid carried by the gas may condense in the first channel section 813a and the second channel section 813b, since the liquid carried by the gas will first condense in the first channel section 813a, the flow velocity of the liquid droplets is relatively high. When these liquid droplets enter the second channel section 813b, they will wash the surface of the second channel section 813b and carry the liquid droplets condensed in the second channel section 813b forward at high speed, thereby effectively reducing the risk of gas blockage in the transfer pipeline 810.

[0106] In some optional embodiments, a first interface 811 is formed in the upper section of the transfer pipe 810, and the hollow channel inside the first interface 811 is inclined upwards in a direction away from the outer surface of the transfer pipe 810. The central axis of the first channel section 813a is coaxial with the central axis of the hollow channel inside the first interface 811. That is, the inclination degree of the hollow channel inside the first interface 811 is the same as the inclination degree of the first channel section 813a.

[0107] The second interface 812 is formed in the 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 downwards 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.

[0108] Based on the above structure, the controlled atmosphere pipe 440 can be connected to the upper part of the transfer pipe 810, and the ventilation pipe 820 can be connected to the side of the transfer pipe 810.

[0109] In one example, the port of the controlled atmosphere duct 440 can be nested within the hollow channel of the first interface 811, and the venting duct 820 can be nested within the hollow channel of the second interface 812.

[0110] In one example, the vent 820 is made of an elastic material. Because the vent 820, made of an elastic material, can fit tightly against the nested interface, the use of the vent 820 to connect the second interface 812 and the vent 610 enables an airtight connection between the second interface 812 and the vent 610.

[0111] In some optional embodiments, the refrigeration and freezing apparatus 10 further includes an oxygen treatment device 300 and a controlled atmosphere piping 440. The oxygen treatment device 300 has a housing 320 and an electrode pair. The interior of the housing 320 defines an electrochemical reaction chamber containing an electrolyte. The electrode pair is disposed within the electrochemical reaction chamber and is used to transfer external oxygen to the electrochemical reaction chamber through an electrochemical reaction. An exhaust port 323 communicating with the electrochemical reaction chamber is provided on the housing 320 for discharging oxygen from the electrochemical reaction chamber.

[0112] The first end of the controlled atmosphere conduit 440 is connected to the ventilation conduit 820, and the second end of the controlled atmosphere conduit 440 is connected to the exhaust port 323, so as to deliver oxygen from the electrochemical reaction chamber to the first storage area 650, thereby creating a high-oxygen preservation atmosphere in the first storage area 650. For example, the first end of the controlled atmosphere conduit 440 can be directly connected to the transfer conduit 810, and the second end can be directly connected to the exhaust port 323.

[0113] With the above structure, the multiple storage compartments 910 of the rotating storage box 900 can switch back and forth between the high-oxygen preservation zone and the non-high-oxygen preservation zone. When oxygen from the electrochemical reaction chamber is delivered to the first storage zone 650 via the controlled atmosphere pipeline 440, a high-oxygen preservation environment can be created in the first storage zone 650. When a storage compartment 910 is switched from the first storage zone 650 to the second storage zone 680, the storage compartment can switch from the high-oxygen preservation zone to the non-high-oxygen preservation zone. When a storage compartment 910 is switched from the second storage zone 680 to the first storage zone 650, the storage compartment 910 can switch from the non-high-oxygen preservation zone to the high-oxygen preservation zone. Therefore, with the above solution of this embodiment, the different storage zones of the refrigeration and freezing device 10 can switch back and forth between the high-oxygen preservation zone and the non-high-oxygen preservation zone.

[0114] Under the function of the gas circuit assembly, the airflow between the controlled atmosphere pipe 440 and the vent 610 can be achieved through the transfer pipe 810 and the vent pipe 820. By cleverly connecting the controlled atmosphere pipe 440 and the vent 610 using the transfer pipe 810 and the vent pipe 820, the port of the controlled atmosphere pipe 440 and the vent 610 do not need to be directly sealed together. This simplifies the connection method between the vent 610 and the controlled atmosphere pipe 440 of the refrigeration and freezing unit 10.

[0115] Figure 7 This is a schematic structural diagram of the oxygen processing device 300 of a refrigeration and freezing apparatus 10 according to an embodiment of the present invention. Figure 8 yes Figure 7 A schematic exploded view of the oxygen processing device 300 of the refrigeration and freezing unit 10 shown.

[0116] The electrode pair may include a cathode plate 330 and an anode plate 340. The electrochemical reaction chamber is the place where the cathode plate 330 and the anode plate 340 carry out the electrochemical reaction. It can be filled with an alkaline electrolyte, such as 1 mol / L NaOH, the concentration of which can be adjusted according to actual needs.

[0117] The housing 320 has a lateral opening 321. For example, the housing 320 may be in the shape of a flat cuboid. The lateral opening 321 may be located on any surface of the housing 320, such as the top surface, bottom surface, or side surface. In one example, the lateral opening 321 may be located on the surface of the housing 320 with the largest area.

[0118] A cathode plate 330 is positioned at a side opening 321 to define, together with the housing 320, an electrochemical reaction chamber for holding the electrolyte and for consuming oxygen through an electrochemical reaction. Oxygen in the air can undergo a reduction reaction at the cathode plate 330: O2 + 2H2O + 4e - →4OH - .

[0119] Anode plate 340 and cathode plate 330 are spaced apart within the electrochemical reaction chamber and are used to provide reactants to cathode plate 330 and generate oxygen through an electrochemical reaction. The OH- produced by cathode plate 330... - An oxidation reaction can occur at the anode plate 340, generating oxygen, i.e.: 4OH⁻ - →O2 + 2H2O + 4e - .

[0120] The above examples of electrochemical reactions of cathode plate 330 and anode plate 340 are merely illustrative. Based on the understanding of the above embodiments, those skilled in the art should be able to easily change the type of electrochemical reaction or extend the structure of oxygen treatment device 300 applicable to other types of electrochemical reactions. All such changes and extensions should fall within the protection scope of this invention.

[0121] In one example, the first end of the controlled atmosphere line 440 can be directly connected to the transfer line 810. The second end of the controlled atmosphere line 440 can be directly or indirectly connected to the exhaust port 323.

[0122] In some optional embodiments, the housing 320 has a replenishment port 322 that connects to the electrochemical reaction chamber. The refrigeration and freezing device 10 also includes a liquid storage module 500, which is disposed within the housing 100 and has a box 510. The interior of the box 510 defines a liquid storage space for storing liquid, which connects to the replenishment port 322 to replenish electrolyte to the electrochemical reaction chamber. The liquid contained in the liquid storage space can be water or electrolyte, and its concentration can be lower than that of the electrolyte contained in the electrochemical reaction chamber.

[0123] The top wall of the housing 510 has an air inlet 512 and an air outlet 513. The air inlet 512 is connected to the exhaust port 323, allowing oxygen discharged from the exhaust port 323 to enter the liquid storage space to filter soluble impurities, such as electrolyte carried by the oxygen. The air outlet 513 allows the filtered oxygen to be discharged and is directly connected to the second end of the controlled atmosphere pipeline 440.

[0124] With the above structure, the controlled atmosphere pipeline 440 can deliver clean oxygen to the storage space.

[0125] In one example, the refrigeration and freezing device 10 may include an inner liner 120 and an inner liner 150. In the above embodiment, the storage container 600 may be disposed inside the inner liner 150. The inner liner 150 may define a variable temperature compartment 152 or a freezing compartment 152. The inner liner 120 defines another storage compartment, such as a refrigeration compartment, which may define another storage space 122, which may be named the second storage space for easy distinction. The cathode plate of the oxygen treatment device 300 is in airflow communication with the storage space 122, thereby reducing the oxygen content of the storage space through an electrochemical reaction.

[0126] In one example, the oxygen treatment device 300 may be disposed within the foam layer. Figure 9 This is a schematic structural diagram of a refrigeration and freezing apparatus according to an embodiment of the present invention. Figure 10 yes Figure 9The schematic internal structure diagram of the refrigeration and freezing device shown has the foam layer omitted to clearly illustrate the structure and connection relationships of each component. In this case, the refrigeration and freezing device 10 may further include a ventilation pipe 200 embedded in the foam layer. The ventilation pipe 200 may include an inlet pipe 210 and a return pipe 220.

[0127] The intake pipe 210 is used to guide the gas in the storage space 122 to the cathode plate 330, and the return pipe 220 is used to guide the gas flowing through the cathode plate 330 back to the storage space 122 to reduce the oxygen content in the storage space 122. For example, the inner liner 120 has a first ventilation port connected to the first end of the intake pipe 210 and a second ventilation port connected to the first end of the return pipe 220 on its wall. Each ventilation port is an opening formed on the wall of the inner liner 120. The second ends of the intake pipe 210 and the return pipe 220 can be connected to the two ends of the cathode plate 330, respectively. Specifically, the second end of the intake pipe 210 can be connected to the upwind side of the cathode plate 330, and the second end of the return pipe 220 can be connected to the downwind side of the cathode plate 330, so that the gas flowing out of the intake pipe 210 can flow into the return pipe 220 after passing through the cathode plate 330.

[0128] With the above structure, the storage space 122 and the oxygen treatment device 300 are connected by the intake pipe 210 and the return pipe 220. The gas with a high oxygen content in the storage space 122 can flow to the cathode plate 330 through the intake pipe 210, so that the cathode plate 330 can use the oxygen in it as a reactant to carry out an electrochemical reaction to form a low oxygen gas with a low oxygen content. This low oxygen gas can be returned to the storage space 122 through the return pipe 220, thereby reducing the oxygen content in the storage space 122.

[0129] The oxygen treatment device 300 can be located at any part of the foam layer, such as the back of the inner liner 120, or the top, bottom, and side of the inner liner 120. In one example, for a French door refrigerator or a T-type refrigerator, the oxygen treatment device 300 can be located in the gap between the upper inner liner 120 and the lower inner liner 120.

[0130] In some alternative embodiments, the side of the foam layer facing away from the inner liner 120 has an assembly groove that communicates with the external environment of the foam layer for assembling the oxygen treatment device 300.

[0131] After the foam layer is formed, the oxygen treatment device 300 can be assembled into the mounting groove, thus being disposed within the foam layer. The mounting groove can be pre-formed during the foam layer forming process. The mounting groove is recessed along the thickness direction of the foam layer towards the inner liner 120, forming a gap between the mounting groove and the inner liner 120. In other words, the mounting groove does not penetrate the foam layer, which prevents the oxygen treatment device 300 assembled into the mounting groove from being in direct contact with the inner liner 120. That is, a certain thickness of heat insulation material is formed between the inner liner 120 and the oxygen treatment device 300.

[0132] By employing the above structure, an assembly groove communicating with the external environment of the foam layer is opened on the side of the foam layer facing away from the inner liner 120, and a gap is formed between the assembly groove and the inner liner 120. This allows the oxygen treatment device 300 to be installed into the assembly groove after the foam layer has been formed, simplifying the assembly and disassembly of the oxygen treatment device 300. Furthermore, since the oxygen treatment device 300 is not in close contact with the inner liner 120, the solution of this embodiment can reduce or avoid the impact of the low-temperature environment of the refrigeration and freezing device 10 on the normal conduction of the electrochemical reaction.

[0133] The oxygen treatment device 300 can be fixed in the mounting groove, and the fixing methods include but are not limited to screwing, snapping, riveting, welding and bonding.

[0134] In some alternative embodiments, the housing 100 further includes a shell 170, which covers the outside of the foam layer to sandwich the foam layer with the inner liner 120. The shell 170 has a back plate, and a mounting groove is formed between the back wall of the inner liner 120 and the back plate of the shell 170. That is, in this embodiment, the oxygen treatment device 300 is disposed within the foam layer on the back of the inner liner 120. The back plate of the shell 170 can close the opening of the mounting groove for a more aesthetically pleasing appearance.

[0135] In one example, the back panel of the housing 170 may have a mounting opening facing the mounting groove. During assembly, the oxygen treatment device 300 can be directly fixed into the mounting groove through the mounting opening without removing the back panel of the housing 170. In a further example, a cover plate may be provided at the mounting opening to conceal it for aesthetic purposes. In another example, the oxygen treatment device 300 can be fixed into the mounting groove first, and then the back panel of the housing 170 can be placed over the back of the foam layer.

[0136] With the above structure, the oxygen treatment device 300 does not need to be pre-installed in the foam layer, avoiding adverse effects of the foaming process on the structure and performance of the oxygen treatment device 300. Furthermore, the assembly process of the oxygen treatment device 300 can be performed on the back of the refrigeration and freezing device 10, which has the advantages of simple assembly process.

[0137] In yet another example, the housing 100 also defines a compressor chamber for mounting the compressor. An oxygen treatment device 300 may be disposed within the compressor chamber. For example, a support plate for securing the compressor is provided at the bottom of the compressor chamber, and the oxygen treatment device 300 may be directly or indirectly disposed on the support plate.

[0138] In one example, the housing 510 is disposed within the foam layer. By disposing the housing 510 of the liquid storage module 500 within the foam layer and connecting the liquid storage space of the housing 510 to the liquid circuit of the oxygen treatment device 300, the liquid stored in the housing 510 can be used to replenish the electrolyte in the oxygen treatment device 300. Since the housing 510 does not occupy the storage space 122, the refrigeration and freezing device 10 can replenish the electrolyte in the oxygen treatment device 300 using the liquid storage module 500 without affecting the volume ratio, allowing the oxygen treatment device 300 to continuously regulate the oxygen content in the storage space 122.

[0139] The housing 510 of the liquid storage module 500 can be located at any part of the foam layer, such as on the side of the inner liner 120, or on the top, bottom, or back of the inner liner 120. For a French door refrigerator or a T-type refrigerator, in one example, the housing 510 of the liquid storage module 500 can be located in the gap between the upper inner liner 120 and the lower inner liner 150.

[0140] In some alternative embodiments, the housing 100 further includes a shell 170, with a foam layer formed between the shell 170 and the inner liner. The shell 170 covers the outside of the foam layer to sandwich the foam layer with the inner liner. In one example, the refrigeration and freezing device may include a refrigeration inner liner, a variable-temperature inner liner, and a freezing inner liner. In a further example, the housing may be disposed within the foam layer outside the refrigeration inner liner.

[0141] Figure 11 This is a schematic structural diagram of the inner liner 120 of a refrigeration and freezing apparatus 10 according to an embodiment of the present invention. The inner liner 120 has an open-shaped interactive window 124, and the foam layer has a mounting groove communicating with the interactive window 124 for assembling a liquid storage module 500. After the foam layer is formed, the liquid storage module 500 can be assembled into the mounting groove, thereby being disposed within the foam layer. The mounting groove can be pre-formed during the foam layer forming process. The mounting groove is recessed along the thickness direction of the foam layer in a direction away from the interactive window 124, and forms a gap with the housing 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 in close contact with the housing 170. That is, a certain thickness of heat insulation material is formed between the housing 170 and the oxygen treatment device 300.

[0142] With the above structure, the liquid storage module 500 does not need to be pre-installed in the foaming layer, avoiding adverse effects of the foaming process on the structure and performance of the liquid storage module 500. Furthermore, the assembly process of the liquid storage module 500 can be performed within the storage space 122, which has the advantages of simple assembly process.

[0143] By creating an interactive window 124 on the inner liner 120 and providing an installation groove communicating with the interactive window 124 in the foam layer, and creating a gap between the installation groove and the shell 170, the liquid storage module 500 can be installed into the installation groove after the foam layer is formed. This simplifies the installation and removal of the liquid storage module 500. Furthermore, since the installation groove does not penetrate the foam layer, the solution in this embodiment can reduce or avoid a significant decrease in the insulation performance of the refrigeration and freezing device 10 due to the installation of the liquid storage module 500 within the foam layer.

[0144] The liquid storage module 500 can be fixed in the mounting groove, and the fixing methods include but are not limited to screwing, snap-fitting, riveting, welding and bonding.

[0145] In some alternative embodiments, the housing 510 has an injection port 514 that communicates with the liquid storage space, and the injection port 514 is exposed through the interactive window 124, thereby allowing external liquid to be injected into the liquid storage space. Figure 12 yes Figure 10 The diagram shows a schematic structural diagram of the liquid storage module of the refrigeration and freezing device. Figure 13 yes Figure 12 A schematic perspective view of the liquid storage module of the refrigeration and freezing device shown. For example, the liquid inlet 514 is provided on the side wall of the housing 510 facing the storage space 122, and is exposed through the interactive window 124.

[0146] By opening an interactive window 124 on the inner liner 150 and connecting the liquid inlet 514 of the housing 510 to the storage space 122 via the interactive window 124, the interactive window 124 can be used as an operation window for the user to replenish the liquid in the storage space. Since the interactive window 124 exposes the liquid inlet 514, when the liquid level in the storage space is insufficient, external liquid can be injected into the storage space through the liquid inlet 514. Therefore, the above-mentioned solution in this embodiment simplifies the liquid replenishment method of the liquid storage module 500, enabling the liquid storage module 500 to continuously replenish electrolyte to the oxygen treatment device 300.

[0147] A cover 550 is provided on the housing 510. The cover 550 is reciprocally positioned at the liquid inlet 514 to open or close the liquid inlet 514. When the cover 550 opens the liquid inlet 514, the liquid inlet 514 is exposed. By providing the cover 550 on the housing 510 and using the cover 550 to open or close the liquid inlet 514, the liquid inlet 514 can be kept open only when receiving external liquid, thereby reducing or preventing foreign matter from entering the liquid storage space and keeping the liquid stored in the liquid storage space clean.

[0148] The cap 550 may be a push-button cap that is rotatably popped up under pressure to extend at least partially into the storage space 122 via the interaction window 124, thereby opening the injection port 514.

[0149] In one example, the bottom of the cover 550 can be connected to the housing 510 via a pivot and is pivotally connected to the housing 510. When the cover 550 closes the injection port 514, its outer surface is coplanar with the outer surface of the housing 510. At this time, the top of the cover 550 can be connected to the housing 510 via a snap-fit ​​structure. When it is necessary to open the injection port 514, the top of the cover 550 can be pressed to disengage the top of the cover 550 from the housing 510. At this time, the cover 550 can rotate around the pivot and extend at least partially into the storage space 122, thereby opening the injection port 514.

[0150] Based on the understanding of the embodiments of this disclosure, those skilled in the art should readily understand the assembly structure between the push-button spring cover and the housing 510, which will not be described in detail here.

[0151] In some alternative embodiments, at least a portion of the housing 510 is made of a transparent material to form a visible area 516 for displaying the liquid volume of the housing 510. The transparent material may be polymethyl methacrylate, polycarbonate, polyethylene terephthalate, or polypropylene, etc.

[0152] In this embodiment, the visible area 516 is exposed through the interactive window 124. The visible area 516 extends longitudinally and is located below the liquid inlet 514. For example, the visible area 516 may also be provided on the side wall of the housing 510 facing the storage space 122 so that it can be exposed through the interactive window 124.

[0153] By providing a visible area 516 on the housing 510 and positioning it opposite the interactive window 124, the interactive window 124 can be used as an observation window for the user to observe the liquid level in the storage space. Since the interactive window 124 exposes the visible area 516, the user can easily observe the liquid level in the storage space. Therefore, the above-described solution in this embodiment provides the user with an intuitive interactive experience. When the liquid level in the storage space is insufficient, the user can take timely measures to replenish the liquid.

[0154] In one example, the interactive window 124 may be located on the side wall of the inner liner 150, and the mounting groove is correspondingly provided between the side wall of the inner liner 150 and the side wall of the shell 170.

[0155] Since the side wall of the inner liner 150 is not easily obstructed by the items stored in the storage space 122 and is close to the user's movable area, an interactive window 124 is set on the side wall of the inner liner 150, and the liquid storage module 500 is embedded in the foam layer on the side of the box 100. This 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 liquid storage information of the liquid storage module 500 without moving the items stored in the storage space 122, and can perform a liquid replenishment operation in time when the liquid storage of the liquid storage module 500 is insufficient.

[0156] In some optional embodiments, the liquid storage module 500 may further include a liquid level sensor disposed within 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 a set value, the refrigeration and freezing device 10 may issue an alarm signal, for example, by transmitting the alarm signal to the user via wireless transmission technology, to remind the user to replenish the liquid in time.

[0157] In some further examples, the housing 510 has a first sidewall flush with the sidewall of the inner liner 150 and enclosing the interaction window 124, and a second sidewall opposite the first sidewall and hidden inside the mounting recess. The injection port 514 is located on the first sidewall. The opening area of ​​the interaction window 124 can be approximately the same as the surface area of ​​the first sidewall of the housing 510, such that the first sidewall of the housing 510 precisely encloses the interaction window 124 and connects the outer surface of the first sidewall with the inner surface of the sidewall of the inner liner 150 to form a complete plane, resulting in an aesthetically pleasing appearance.

[0158] The injection port 514 can be located in the upper section of the first sidewall. The visible area 516 can also be located on the first sidewall, for example, in the middle or lower section of the first sidewall.

[0159] The housing 510 can be generally flattened into a cuboid shape. The housing 510 has an outlet 511 that connects to the liquid storage space. The housing 510 also has a top wall and a bottom wall connected between the first and second side walls and arranged vertically opposite each other. The bottom wall has an outlet 511 that connects to a replenishment port 322 to replenish electrolyte to the electrochemical reaction chamber.

[0160] In some optional embodiments, the housing 510 further has a third sidewall and a fourth sidewall connected between the first sidewall and the second sidewall and disposed opposite each other in the horizontal direction. The outer surface of the third sidewall and / or the fourth sidewall is connected to a fastener 517, which has a screw hole for engaging with a screw to fix the housing 510 to the mounting groove.

[0161] The refrigeration and freezing device 10 also includes a liquid replenishment pipe 420 embedded in the foam layer. The first end of the liquid replenishment pipe 420 is connected to the liquid replenishment port 322 of the oxygen treatment device 300, and the second end is connected to the liquid outlet 511 of the liquid storage module 500. This guides the liquid flowing out of the liquid storage space from the liquid outlet 511 to the liquid replenishment port 322, thereby replenishing the electrochemical reaction chamber. The liquid outlet 511 is higher than the liquid replenishment port 322, so that the liquid in the liquid storage space can automatically flow into the electrochemical reaction chamber under gravity without the need for a power unit.

[0162] Of course, in other examples, the outlet 511 can also be changed to be lower than or level with the replenishment outlet 322. In this case, a pump can be installed on the replenishment line 420 to drive the liquid in the storage space into the electrochemical reaction chamber under the action of the pump; or the siphon principle can be used to make the liquid in the storage space flow into the electrochemical reaction chamber.

[0163] In some further examples, a one-way valve may be provided on the replenishment line 420 to allow liquid from the outlet 511 to pass through in one direction, ensuring the unidirectional flow of liquid through the replenishment line 420.

[0164] The refrigeration and freezing device 10 also includes a filter pipe 430 embedded in the foam layer. The first end of the filter pipe 430 is connected to the exhaust port 323 of the oxygen treatment device 300, and the second end of the filter pipe 430 is connected to the air inlet 512 of the box body 510, so as to guide the oxygen flowing out of the exhaust port 323 to the air outlet 513, thereby entering the liquid storage space for filtration.

[0165] The liquid storage module 500 may further include a filter pipe 540 and an outlet pipe. The filter pipe 540 is inserted into the liquid storage space from the inlet 512 and extends to the bottom section of the liquid storage space to guide the oxygen to be filtered into the liquid storage space, allowing soluble impurities in the oxygen to dissolve in the liquid storage space. The outlet pipe is inserted into the housing 510 from the outlet 513 and extends to the upper section of the liquid storage space, located above the liquid stored in the liquid storage space, to guide the filtered oxygen out through it.

[0166] Using the above method, the oxygen to be filtered can reach the liquid storage space under the guidance of the filter pipe 540, and flow through the liquid stored in the liquid storage space, causing soluble impurities in the oxygen to dissolve in the liquid storage space, thus completing the gas purification. The purified gas can flow into a designated space under the guidance of the outlet pipe, thereby regulating the oxygen content of the space.

[0167] In an optional embodiment, the liquid storage module 500 further includes a gas resistance mechanism 530 disposed within the liquid storage space, which divides the liquid storage space into a filtration zone and a non-filtration zone that block the gas flow. The filtration zone is used to allow gas flowing into the air inlet 512 to pass through it for filtration. The non-filtration zone is used to receive liquid from external sources.

[0168] The filtration zone and the non-filtration zone can be arranged side-by-side laterally. The air-blocking mechanism 530 blocks a portion of the liquid path between the filtration zone and the non-filtration zone, ensuring liquid flow between them even when the air path is blocked. For example, the air-blocking mechanism 530 is a partition-like structure located between the filtration zone and the non-filtration zone, extending downwards from the lower surface of the top wall of the housing 510 and forming a gap with the upper surface of the bottom wall of the housing 510. The filtration zone is located on one side of the air-blocking mechanism 530, and the non-filtration zone is located on the other side. The air inlet 512 and the air outlet 513 can be respectively located on the top wall of the area where the filtration zone is located. The liquid inlet 514 can be located on the top wall of the area where the non-filtration zone is located.

[0169] By employing the above structure, and by setting an air resistance mechanism 530 within the liquid storage space, and using the air resistance mechanism 530 to divide the liquid storage space into a filtration zone and a non-filtration zone with blocked airflow, the function of purifying gas can be achieved only within the filtration zone. Since the filtration zone is only a sub-space of the liquid storage space, and the airflow between it and other areas of the liquid storage space is blocked, the gas entering the air inlet 512 can only flow within the filtration zone and will not freely diffuse into the non-filtration zone, thus preventing rapid discharge. Therefore, the liquid storage module 500 of this embodiment has a high purified gas release rate.
