Figure 1 is a schematic structural diagram of a refrigeration and freezing device 10 according to an embodiment of the present invention. The refrigeration and freezing device 10 in the embodiment of the present invention may be a refrigerator, or a refrigeration equipment with a low-temperature storage function such as a refrigerator, a freezer, or a refrigerator. The refrigeration and freezing device 10 may generally include an inner tank 120 and a liquid storage device 500 .

FIG. 2 is a schematic structural diagram of the inner tank 120 of the refrigeration and freezing device 10 shown in FIG. 1 . The interior of the liner 120 defines a storage compartment 122 . The storage compartment 122 may be a refrigeration compartment, a freezing compartment or a variable temperature compartment, and of course may also be a cryogenic compartment or any other compartment.

FIG. 3 is a schematic internal structure diagram of the refrigeration and freezing device 10 shown in FIG. 1 . FIG. 4 is a schematic exploded view of the internal structure of the refrigeration and freezing device 10 shown in FIG. 3 . The liquid storage device 500 is disposed in the storage compartment 122 . The liquid storage device 500 includes a liquid storage container 510, and the interior of the liquid storage container 510 defines a liquid storage space. The liquid storage space is used to store liquid. Liquid types include, but are not limited to, water. The liquid stored in the liquid storage space can be set according to the type of liquid required by the liquid demand side to meet the rehydration needs of the liquid demand side.

The liquid storage container 510 is formed with at least one fluid interface 550 that communicates with the liquid storage space. The fluid interface 550 communicates with the fluid port 130 in one-to-one correspondence, so that the liquid storage space communicates with the external environment of the inner bladder 120 . In this embodiment, there are one or more fluid interfaces 550 and one or more fluid ports 130 . The fluid interface 550 and the fluid port 130 are connected in a one-to-one correspondence. This means that when the fluid interface 550 and the fluid port 130 are one, they are connected with each other to form a fluid transport channel. When the fluid interface 550 and the fluid port 130 are multiple, respectively. At this time, one fluid interface 550 is correspondingly connected to one fluid port 130, thereby forming multiple fluid delivery channels. There are the same number of fluid interfaces 550 as fluid ports 130 .

Fluid interface 550 and fluid port 130 are respectively used to allow the passage of fluid. Fluid types include liquids and/or gases. That is to say, relying on the fluid delivery channel established by the fluid interface 550 and the fluid port 130, the liquid storage space can exchange liquid with the external environment of the inner bladder 120, and can also exchange gas with the external environment of the inner bladder 120.

The fluid delivery pipeline 520 is connected one by one between the fluid interface 550 and the corresponding fluid port 130. This means that when there is one fluid interface 550 and one fluid port 130, one fluid delivery pipeline 520 is connected between them. A fluid transport channel is thereby formed. When there are multiple fluid interfaces 550 and fluid ports 130 respectively, a fluid transport pipeline 520 is connected correspondingly between one fluid interface 550 and one fluid port 130, thereby forming multiple fluid transport channels.

When the fluid transport pipeline 520 is provided between the fluid interface 550 and the fluid port 130, a regulating device for the fluid flow and flow direction can be provided on the fluid transport pipeline 520.

The number of hollow cylindrical channels defined by the pipeline assembly 540 is one or more, and is the same as the number of fluid delivery pipelines 520 . In one example, there may be at least one pipeline assembly 540 , and each pipeline assembly 540 defines a hollow cylindrical channel. In another example, each tubing assembly 540 may define two hollow cylindrical channels.

In another example, the number of hollow cylindrical channels defined by the tubing assembly 540 is twice the number of fluid delivery tubing 520 . In a further example, a pipeline assembly 540 is provided at both ends of each fluid delivery pipeline 520, and each pipeline assembly 540 defines a hollow cylindrical channel to respectively fix a fluid delivery channel. end, thereby further improving the structural stability of the fluid delivery structure and reducing or avoiding fluid leakage due to loose connections at the pipe openings. At least a portion of the pipeline assembly 540 is fixedly disposed inside the assembly cavity 530; of course, another portion of the pipeline assembly 540 can be disposed outside the assembly cavity 530 to facilitate fixing the end of the fluid delivery pipeline 520.

In one example, the fluid delivery conduit 520 extends from front to back in a horizontal direction. The pipeline assembly 540 has a first assembly part and a second assembly part, wherein the first assembly part is fixedly connected with the assembly cavity or is integrated with the assembly cavity, and defines a downwardly concave arc-shaped plate. The concave arc-shaped plate serves as the lower channel wall of the hollow cylindrical channel. The second assembly portion defines an upwardly concave arc-shaped plate as an upper channel wall of the hollow cylindrical channel. The upper channel wall and the lower channel wall jointly define a complete hollow cylindrical channel for the fluid delivery pipeline 520 to be inserted therein to achieve fixed assembly.

The second assembly part is detachably assembled above the first assembly part. The second assembly part also defines a First threaded holes on both sides of the channel wall. The second assembly part is correspondingly formed with second threaded holes located on both sides of the lower channel wall and facing the first threaded holes one by one, so as to achieve detachable assembly through screwing.

The fluid delivery pipeline 520 may pass through the assembly cavity 530 to communicate with the fluid port 130 and the fluid interface 550 . The liquid storage device 500 may also include a packaging cover 541, which is disposed on the top of the assembly cavity 530 to protect the pipeline and prevent dust.

The liquid storage container 510 has a container cover 580 that is detachably disposed on the top of the liquid storage container 510 . The container cover 580 covers the opening 512 on the top of the liquid storage container 510 to close the opening 512 . A sealing ring may be provided at the joint between the container cover 580 and the liquid storage container 510 to enhance the sealing effect and prevent air leakage. A liquid injection port 587 is formed on the container cover 580 to allow external liquid to be injected into the liquid storage space. The liquid filling port 587 is provided with a movable sub-cover 586 to open or close the liquid filling port 587 .

The container cover 580 is formed with outwardly protruding claws. The edge of the opening 512 of the liquid storage container 510 may be provided with a locking groove for the claw to be inserted into the opening 512 . When the container cover 580 is covered at the opening 512 and the claws are engaged with the engaging groove, it indicates that the container cover 580 has been installed in place and the opening 512 can be closed.

In some optional embodiments, the fluid port 130 is a hollow cylindrical interface formed on the inner bladder 120 and raised toward the corresponding fluid interface 550, so as to be removably nested with the first end of the fluid delivery pipeline 520. connect. The fluid interface 550 is a hollow cylindrical interface formed on the liquid storage container 510 and raised toward the corresponding fluid port 130 so as to be nested and detachably connected to the second end of the fluid delivery pipeline 520 .

That is to say, the fluid port 130 and the fluid interface 550 can be respectively nested with the fluid delivery pipeline 520 to achieve connection, and can be respectively de-embedded from the fluid delivery pipeline 520 to achieve separation.

Of course, the fluid port 130 can also be further raised in a direction away from the corresponding fluid interface 550 so as to be nested and detachably connected to the pipeline provided outside the inner bladder 120 .

When the fluid port 130 and the fluid interface 550 are respectively hollow cylindrical interfaces, and are respectively nested with the ends of the fluid delivery pipeline 520 and disposed in a detachable manner, the fluid delivery pipeline 520 and the fluid can be connected by plugging. The port 130 and the fluid interface 550 are connected to form a smooth fluid delivery channel, which is beneficial to simplifying the assembly process of the fluid delivery structure and reducing the manufacturing cost of the entire machine.

In some optional embodiments, the fluid port 130 includes a liquid port 131 for communicating liquid. The fluid interface 550 includes a liquid circuit interface 551 for flowing liquid. The fluid delivery pipeline 520 includes a liquid delivery pipeline 521 connected between the fluid port 131 and the fluid interface 551 .

At this time, the liquid in the liquid storage space can flow out of the storage compartment 122 through the liquid interface 551, the liquid delivery pipe 521 and the liquid port 131 in order to flow into the liquid demand end located outside the storage compartment 122. Thereby replenishing fluid to the liquid demand side to keep the liquid demand side working.

Of course, in another example, liquid from the external environment of the inner bladder 120 can also flow into the liquid storage space via the liquid port 131, the liquid delivery pipe 521 and the liquid interface 551, thereby replenishing liquid to the storage box.

In some further embodiments, fluid port 130 also includes at least one gas port for fluid gas. The fluid interface 550 also includes at least one gas path interface for flowing gas and communicating with the gas path ports one by one. The fluid delivery pipeline 520 also includes at least one gas delivery pipeline connected one by one between the gas port and the corresponding gas interface.

That is, there may be one or more air path ports. There can also be one or more pneumatic interfaces. The gas transmission pipelines are connected one by one between the gas pipeline interface and the corresponding gas pipeline port. This means that when there is one gas pipeline interface and one gas pipeline port respectively, a gas transport pipeline is connected between them, thus forming a gas pipeline. As for the transport channel, when there are multiple gas channel interfaces and multiple gas channel ports, a gas transport pipeline is correspondingly connected between one gas channel interface and one gas channel port, thereby forming multiple gas transport channels.

In one example, when there is one gas port, one gas interface, and one gas delivery pipeline respectively, the gas from the external environment of the inner tank 120 can flow into the liquid storage space through the gas port, the gas delivery pipeline, and the gas pipeline interface. to filter soluble impurities. At this time, the filtered gas can be discharged into the storage compartment 122 .

In another example, when there are multiple gas ports, gas interfaces, and gas delivery pipes, the gas from the external environment of the inner bladder 120 can flow into the liquid storage space through a gas delivery channel to filter soluble impurities. At this time, the filtered gas can flow to the external environment of the inner tank 120 through another gas delivery channel for utilization.

In some optional embodiments, there are two air path interfaces, namely the air inlet interface 552 and the air outlet interface 553. There are two air path ports, namely the air inlet port 132 opposite to the air inlet interface 552 and the air outlet port 133 opposite to the air outlet interface 553.

There are two gas delivery pipelines, namely an air inlet pipeline 522 and an air outlet pipeline 523. The air inlet pipeline 522 is connected between the air inlet port 132 and the air inlet interface 552, and is used to conduct gas from the external environment of the liner 120. It is led to the liquid storage space to filter soluble impurities. The gas outlet pipeline 523 is connected between the gas outlet interface 553 and the gas outlet port 133 for discharging the filtered gas to the external environment of the inner bladder 120 .

Using the above solution, the liquid storage device 500 can not only supply liquid to the liquid demand end located outside the liner 120, but also filter out soluble impurities in the gas from the external environment of the liner 120, so as to supply liquid to the external environment of the liner 120 ( For example, the gas demand side) provides clean gas to meet the air conditioning needs.

In some optional embodiments, the liquid circuit interface 551 is lower than the gas circuit interface. The liquid port 131 is lower than the gas port. And the liquid circuit port 131 is opposite to the liquid circuit interface 551 .

That is, the liquid circuit interface 551 is provided below the gas circuit interface. In one example, the liquid circuit interface 551 is provided at the bottom section of the liquid storage container 510 . The gas line interface is provided at the top section of the liquid storage container 510 . The liquid in the liquid storage space can automatically flow out of the liquid line interface 551 under the action of gravity, flow into the liquid delivery pipeline 521, and then flow out of the inner tank 120 and enter the liquid demand end. The gas to be filtered from the external environment of the liner 120 can flow into the liquid storage space under the guidance of the air path interface, and first flow downward and then upward in the liquid storage space to extend the flow path and fully disperse the soluble impurities. Dissolved in the liquid stored in the liquid storage space.

In some optional embodiments, the liquid storage device 500 further includes a power mechanism, which is disposed at the liquid circuit interface 551 or on the flow path between the liquid circuit interface 551 and the liquid circuit port 131 for driving the liquid circuit interface. 551 The liquid flowing to the liquid line port 131 is pressurized.

In one example, the power mechanism is a pump. In another example, the power mechanism can also be configured as other types of power mechanism components, such as a supercharger. In one example, a power mechanism may be provided on the liquid delivery pipeline 521 to accelerate the flow of liquid flowing from the liquid circuit interface 551 to the liquid circuit port 131 , thereby improving the fluid replenishment efficiency of the liquid storage device 500 . Of course, the power mechanism can also be provided at the fluid port 131.

In some optional embodiments, the liquid storage device 500 further includes a one-way valve 570, which is disposed at the air inlet interface 552 or on the flow path between the air inlet port 132 and the air inlet interface 552. For example, it can be disposed at The air inlet pipe 522 is used to allow the fluid from the air inlet port 132 to pass in one direction, thereby preventing backdraft. Of course, the one-way valve 570 can also be disposed at the air intake port 132 .

In the above embodiment, the inner bladder 120 can be integrally injection molded. In other alternative embodiments, the inner bladder 120 may include two different parts. For example, the inner bladder 120 may include a body portion 125 and a fixing plate 126 . FIG. 8 is a schematic exploded view of the inner pot 120 of the refrigeration and freezing device 10 shown in FIG. 2 . The body part 125 has a notch 125a. The fixing plate 126 closes the notch 125a to define the inner bladder 120 together with the body portion 125, and forms a part of the wall of the inner bladder 120. Fixed plate 126 defines fluid port 130 .

The body part 125 and the fixing plate 126 can be independently molded through an injection molding process. Since the fluid port 130 is disposed on the fixed plate 126, there is no need to mold the fluid port 130 on the body part 125. Therefore, using the solution of this embodiment can simplify the molding process of the inner bladder 120 and reduce the difficulty of the molding process.

The body portion 125 may define a main body outline of the inner bladder 120 . The fixing plate 126 can cover the notch 125a and be fixedly connected with the main body part to close the notch 125a, thereby defining a complete inner bladder 120 together with the main body part 125.

The edge of the fixing plate 126 is provided with a positioning structure. Before the inner pot 120 is foamed, the fixing plate 126 can be stuck on the inner pot 120 through a positioning mechanism. After the liner 120 is foamed, the fluid port 130 can be connected to the first end of the fluid delivery pipe 520 one by one, and then the liquid storage container is installed in the storage compartment 122 so that the fluid interface 550 is connected to the fluid delivery pipe. The second end of road 520 is connected one by one. The pipeline docking process can be completed in one step without the need for separate intubations.

In some alternative embodiments, the fixation plate 126 forms a portion of the rear wall of the liner 120 . The liquid storage container 510 is disposed on the front side of the fixing plate 126 and is spaced apart from the rear wall of the inner tank 120 to define an installation space for assembling pipelines (eg, fluid delivery pipelines 520 ). This installation space can be used to install at least a portion of the assembly cavity 530 . Pipe fittings 540 and fluid delivery pipes 520 may be further disposed within the installation space.

In one example, the assembly cavity 530 is fixedly connected to the plate-shaped connector. The plate-shaped connector is fixedly connected to the wall of the inner bag 120 so that the assembly cavity 530 is fixed in the storage compartment 122 . In one example, the plate-shaped connector has an insertion portion that is plugged into the inner surface of the side wall of the inner pot 120 and a screw-connected portion that is threaded with the inner surface of the side wall of the inner pot 120 . In one example, the plate-shaped connector also has a positioning post inserted into a recess of the side wall of the inner bladder 120 to achieve positioning.

The outer surface of the bottom wall of the liquid storage container 510 has limiting ribs protruding outward. The upper surface of the bottom wall of the storage compartment 122 has a limiting groove into which the limiting rib is inserted to achieve positioning.

In some alternative embodiments, the fixed plate 126 defines a fluid port 130, which may be an optical hole. The fluid delivery pipelines 520 can be plugged into corresponding fluid ports 130 one by one. Figure 9 is a schematic internal structure diagram of the refrigeration and freezing device 10 according to one embodiment of the present invention. FIG. 10 is a schematic exploded view of the internal structure of the refrigeration and freezing device 10 shown in FIG. 9 . The inner pot 120 may further be provided with a connecting plate 127 , which is fixedly connected to the inner pot 120 and defines connection ports that are one-to-one opposite to the fluid ports 130 . The connecting plate 127 is formed with a dimple that is recessed in a direction away from the fixed plate 126, and the bottom of the dimple is oriented away from the fixed plate 126. The direction 126 bulges outward to form a connection port connecting to the external space. Fluid delivery line 520 is inserted into the recess to achieve connection. Using the solution of this embodiment, the connecting plate 127 can connect multiple fluid delivery pipelines 520 at one time, which is simple and fast, and simplifies the intubation step.

In some optional embodiments, the liquid storage device 500 further includes a fluid guiding mechanism 590 . The liquid storage container 510 has an opening 512 . Figure 11 is a schematic structural diagram of the container cover 580 and the fluid guide mechanism 590 of the liquid storage device 500 according to an embodiment of the present invention.

The container cover 580 covers the opening 512 to jointly define a sealed liquid storage space with the liquid storage container 510 .

The fluid guide mechanism 590 is fixedly connected to the container cover 580 or is integrated with the container cover 580, and is inserted into the liquid storage space when the container cover 580 covers the opening 512 to define a guide channel for guiding fluid flow. The guide channel defines a flow path for the fluid in the liquid storage space. Under the action of the fluid guide mechanism 590, the fluid flowing into the liquid storage space can flow along the fluid flow path defined by the guide channel, thereby reducing or avoiding disordered diffusion of the fluid.

Since the fluid guide mechanism 590 is fixedly connected to the container cover 580 or is integrated with the container cover 580, the fluid guide mechanism 590 can move synchronously with the container cover 580 to insert into the liquid storage space when the container cover 580 covers the opening 512. . When the fluid guide mechanism 590 is fixedly connected to the container cover 580, the fluid guide mechanism 590 and the container cover 580 can be connected by snapping, screwing, bonding, riveting or welding. When the fluid guide mechanism 590 and the container cover 580 are integrated, the fluid guide mechanism 590 and the container cover 580 can be integrally molded through an injection molding process.

The fluid guide mechanism 590 is fixedly connected to the container cover 580 or the fluid guide mechanism 590 and the container cover 580 are formed into one piece, and the fluid guide mechanism 590 is inserted into the liquid storage container when the container cover 580 opens 512 of the liquid storage container 510 space to define a guide channel for guiding fluid flow. Since the fluid guide mechanism 590 does not need to be fixedly assembled in the liquid storage space, the fluid guide mechanism 590 of the liquid storage device 500 can be optimized using the solution of this embodiment. The assembly method simplifies the assembly process.

The guide channel defined by the fluid guide mechanism 590 can be connected to the external environment of the liquid storage container 510 to allow fluid from the external environment to flow through the liquid storage space under the guidance of the guide channel. The fluid can be a gas or a liquid.

When the fluid is gas, under the action of the guide channel defined by the fluid guide mechanism 590, the fluid can flow along a relatively fixed path and flow out of the liquid storage space to ensure gas scrubbing efficiency. When the fluid is a liquid, under the action of the guide channel defined by the fluid guide mechanism 590, the fluid can flow to a designated part of the liquid storage space to meet the liquid replenishment needs and/or liquid quality adjustment needs of the liquid storage space.

Figure 12 is a schematic exploded view of the liquid storage container 510, the container cover 580 and the fluid guide mechanism 590 of the liquid storage device 500 according to an embodiment of the present invention. In some optional embodiments, the guide channel includes an air inlet channel 591a and an air outlet channel 592a, which are respectively connected to the external environment of the liquid storage space, so that the gas from the external environment flows into the liquid storage space through the air inlet channel 591a, and passes through the air outlet. The channel 592a flows out of the liquid storage space and filters soluble impurities when flowing to the air outlet channel 592a.

FIG. 13 is a schematic perspective view of the assembly structure of the liquid storage container 510, the container cover 580, and the fluid guide mechanism 590 of the liquid storage device 500 shown in FIG. 12 . The air inlet channel 591a can be connected to the air outlet channel 592a, for example connected directly or indirectly. In one example, the air inlet passage 591a is indirectly connected to the air outlet passage 592a. For example, the air inlet channel 591a and the air outlet channel 592a may be connected through the liquid stored in the liquid storage space. The gas flowing into the liquid storage space from the air inlet channel 591a can first flow through the liquid stored in the liquid storage space, and then flow out of the liquid storage space through the air outlet channel 592a, so that the soluble impurities in the gas are dissolved in the liquid storage when flowing to the air outlet channel 592a. in the liquid stored in the space.

In another example, the air inlet passage 591a communicates directly with the air outlet passage 592a. The air outlet channel 592a may extend from the exhaust end of the air inlet channel 591a to the air outlet interface 553 described below. The upstream section of the air outlet channel 592a is the liquid stored in the liquid storage space, and the downstream section is the pipeline. At this time, the gas flowing into the liquid storage space from the air inlet channel 591a can first flow through the upstream section of the gas outlet channel 592a, and then flow out of the liquid storage space through the downstream section of the gas outlet channel 592a, so that the soluble impurities in the gas can flow through the liquid storage space. The upstream section of the air outlet channel 592a is dissolved in the liquid stored in the liquid storage space.

The container cover 580 and the fluid guide mechanism 590 can be integrally molded through an injection molding process to form a single piece. Using the above solution, since the air inlet channel 591a and the air outlet channel 592a can be directly formed on the container cover 580 and can be used to guide the flow process of gas in the liquid storage space, therefore, the gas can flow through the liquid storage space along a preset path. There is almost no irregular flow in the liquid space, which is beneficial to increasing the recovery amount of filtered gas.

In some optional embodiments, the container cover 580 is provided with an air inlet interface 552 and an air outlet interface 553. The air inlet interface 552 is connected to the air inlet channel 591a and is configured to allow gas from the external environment to flow into the air inlet channel 591a. The air outlet interface 553 is connected to the air outlet channel 592a and is configured to allow filtered gas to flow out of the air outlet channel 592a. The air inlet interface 552 and the air outlet interface 553 can be formed on the container cover 580 through an injection molding process. In one example, the air inlet channel 591a is directly connected to the air inlet interface 552, and the air outlet channel 592a is directly connected to the air outlet interface 553.

By providing an air inlet interface 552 and an air outlet interface 553 on the container cover 580, the air inlet interface 552 and the air outlet interface 553 can be connected to external pipelines, and the gas to be filtered from the external environment of the liquid storage space can be transported to the liquid storage through the pipelines. Space, the filtered gas can also be transported to the designated space through pipelines, so that the gas can flow in a directional manner.

The air inlet interface 552 and the air outlet interface 553 may respectively be hollow cylindrical interfaces formed on the container cover 580 and raised to the outside of the liquid storage space to facilitate insertion with external pipelines.

In a further example, the air inlet interface 552, the air outlet interface 553, and the fluid guide mechanism 590 are all molded on the container cover 580 through an injection molding process to form an integrated piece. In this way, related operations involving connection and fixing can be omitted, and only the The container cover 580 covers the opening 512 of the liquid storage container 510 to complete the assembly of the fluid transport structure, which is simple and efficient.

Of course, in another example, the air inlet interface 552, the air outlet interface 553 and/or the fluid guide mechanism 590 can also be fixedly connected to the container cover 580. Fixed connection methods include but are not limited to screwing, snapping, bonding, welding or riveting.

In some optional embodiments, the fluid guiding mechanism 590 includes an air filter tube 591 and an air outlet tube 592 . The air filter pipe 591 is connected to the air inlet interface 552 and extends from the inner surface of the container cover 580 toward the liquid storage space to define an air inlet channel 591a.

The air outlet pipe 592 is connected to the air outlet interface 553 and extends from the inner surface of the container cover 580 toward the liquid storage space to define an air outlet channel 592a. The depth of the air outlet pipe 592 in the liquid storage space is higher than the depth of the air filter pipe 591 in the liquid storage space. That is, the length of the air outlet pipe 592 is shorter than the length of the air filter pipe 591 . In one example, the air filter pipe 591 can extend to the bottom section of the liquid storage space, and the air outlet pipe 592 can extend to the top section of the liquid storage space. The air filter pipe 591 and the air outlet pipe 592 can be straight pipes respectively.

Using the above solution, the gas to be filtered can reach the bottom section of the liquid storage space under the guidance of the air filter pipe 591, and first move downward and then move upward in the liquid storage space, so that the soluble impurities in the gas are dissolved. The liquid stored in the liquid storage space completes the purification of gas. The purified gas can flow centrally near the air outlet pipe 592 and flow out of the liquid storage space under the guidance of the air outlet pipe 592, thereby completing the purification of the gas. When the depth of the air outlet pipe 592 in the liquid storage space is higher than the depth of the air filter pipe 591 in the liquid storage space, the upward movement path of the gas can be extended, so that the soluble impurities in the gas can be fully dissolved in the liquid stored in the liquid storage space. .

In some optional embodiments, the fluid guide mechanism 590 also includes an air path blocking portion 595, which extends from the inner surface of the container cover 580 toward the liquid storage space, and separates the liquid storage space from the filtered air blocked by the air path. Zone 515 and non-filter zone 516. in

The air filter area 515 communicates with the air inlet channel 591a and the air outlet channel 592a, and is configured to allow gas from the external environment to flow therethrough to achieve filtration. That is to say, the air filter area 515 is in air flow communication with the air inlet channel 591a and the air outlet channel 592a. The gas flowing into the liquid storage space through the air inlet channel 591a can flow through the air filter area 515, and then merge into the air filter area 515. Air outlet channel 592a. The air filter pipe 591 and the air outlet pipe 592 can be inserted into the air filter area 515.

The non-air filter area 516 is the liquid storage space outside the air filter area 515 . In this embodiment, the air filter area 515 is a subspace within the liquid storage space, and the non-air filter area 516 may be another subspace within the liquid storage space.

The gas path blocking part 595 separates the liquid storage space into a gas filter area 515 and a non-gas filter area 516 that block the gas path. This means that the gas path blocking part 595 blocks the gas filter area 515 and the non-gas filter area 516. The air flow passage prevents the gas flowing through the air filter area 515 from entering the non-air filter area 516 . That is to say, the gas flowing into the liquid storage space through the air inlet channel 591a can only flow in the gas filter area 515.

Using the above structure, by providing a gas path blocking part 595 in the liquid storage device 500, and using the gas path blocking part 595 to separate the liquid storage space into a gas filter area 515 with a gas path blocked and a non-gas filter area 516, it can be realized The function of purifying gas is only performed in the gas filter area 515 . Since the air filter area 515 is only a subspace of the liquid storage space and is blocked from other areas of the liquid storage space, the gas from the external environment of the liquid storage space can only flow in the air filter area 515, while It will not freely diffuse into the non-filtered gas area 516 and thus cannot be discharged quickly. Therefore, the liquid storage device 500 of this embodiment has a high purification gas release rate.

In some alternative embodiments, the non-filtered area 516 is used to receive liquid from outside the liquid storage space. For example, the container lid 580 may be provided with a liquid filling port 587 connected to the non-air filtering area 516 to allow external liquid to flow into the non-air filtering area 516 through the liquid filling port 587 . The liquid filling port 587 is provided with a movable sub-cover 586 to open or close the liquid filling port 587 .

When the gas path blocking part 595 blocks the gas path between the gas filtering area 515 and the non-gas filtering area 516, the gas filtering process performed in the gas filtering area 515 and the liquid injection process performed in the non-gas filtering area 516 Or the liquid discharging process can be carried out at the same time without mutual interference.

The gas path blocking part 595 blocks a part of the liquid path between the gas filtering area 515 and the non-gas filtering area 516, so that the gas filtering area 515 and the non-gas filtering area 516 maintain liquid path communication when the gas path is blocked. That is to say, the air path blocking part 595 only blocks the air path between the air filter area 515 and the non-air filter area 516, but does not block the liquid path between the air filter area 515 and the non-air filter area 516. .

When the non-gas filtering area 516 is used to receive liquid from outside the liquid storage space, and the gas path blocking part 595 blocks a part of the liquid path between the gas filtering area 515 and the non-gas filtering area 516, the gas filtering area 515 and the non-gas filtering area 516 are separated. When the air filter area 516 maintains liquid path communication when the air path is blocked, the liquid level difference between the air filter area 515 and the non-air filter area 516 of the liquid storage device 500 can be reduced or avoided, and the pressure of the air filter area 515 can be easily controlled. Liquid volume.

Based on the above structure, the air filter area 515 and the non-air filter area 516 can always maintain the same liquid level, and liquid exchange can be smoothly carried out between them. In this way, the liquid in the air filter area 515 can maintain a flowing state to a certain extent without regular replacement. Moreover, the substances dissolved in the air filter area 515 can enter the non-air filter area 516 and flow back into the use environment, such as the oxygen treatment device 300 described below, so as to be recycled.

In some optional embodiments, the opening 512 of the liquid storage container 510 is disposed on the top of the liquid storage container 510 . The air path blocking portion 595 is a partition-shaped plate located between the air filter area 515 and the non-air filter area 516 and extends downward from the lower surface of the container cover 580 and forms a gap with the upper surface of the bottom wall of the liquid storage container 510 The structure is such that the air filter area 515 and the non-air filter area 516 are in fluid communication. The air path blocking part 595 of the partition-like structure may be a vertical plate.

This gap serves as a window for liquid exchange between the air filter area 515 and the non-air filter area 516 . The bottom end of the air filter tube 591 is higher than the bottom end of the air path blocking part 595, and the distance from the bottom end of the air path blocking part 595 is greater than a preset threshold. The preset threshold can be determined based on the downward movement of the gas flowing into the liquid storage space from the air filter pipe 591 in the liquid storage space. For example, the preset threshold can be greater than or equal to the downward movement of the gas in the liquid storage space.

In some optional embodiments, the liquid storage container 510 has a liquid line interface 551 connected to the liquid storage space and configured to allow liquid in the liquid storage space to flow out. And the liquid circuit interface 551 is provided at the bottom section of the liquid storage container 510 . In one example, the liquid line interface 551 can be connected to the non-filtered gas area 516 to allow the liquid in the non-filtered gas area 516 to flow out of the liquid outlet space through the liquid line interface 551 and flow into the use environment, such as the oxygen treatment device 300 described below. Of course, in another example, the liquid line interface 551 can also be connected to the air filter area 515 to allow the liquid inside the air filter area 515 to flow out of the liquid outlet space through the liquid line interface 551 and flow into the use environment, such as the following oxygen treatment device 300.

In one example, the air inlet interface 552 and the air outlet interface 553 may be hollow cylindrical interfaces respectively, and extend in a horizontal direction, for example, may extend from front to back. The air filter pipe 591 and the air outlet pipe 592 may be hollow straight pipes respectively, and extend from top to bottom.

In some optional embodiments, the liquid storage device 500 may further include a liquid level sensor, which is disposed in the liquid storage space for detecting the liquid level in the liquid storage space. The refrigeration and freezing device 10 may be located in the liquid storage space. An alarm is issued when the liquid level exceeds the preset range to prompt the user to refill the fluid storage space or stop refilling.

Figure 14 is a schematic structural diagram of the oxygen treatment device 300 of the refrigeration and freezing device 10 according to an embodiment of the present invention. FIG. 15 is a schematic exploded view of the oxygen treatment device 300 of the refrigeration and freezing device 10 shown in FIG. 14 . In some optional embodiments, the refrigeration and freezing device 10 further includes an oxygen treatment device 300 . Among them, the oxygen treatment device 300 has a casing 320 and an electrode pair. The interior of the casing 320 defines an electrochemical chamber containing electrolyte. Chemical reaction chamber, the electrode pair is arranged in the electrochemical reaction chamber and used to transfer external oxygen to the electrochemical reaction chamber through electrochemical reaction. The electrochemical reaction chamber can be used as a liquid demand end.

The housing 320 is provided with a liquid replenishing port 322 connected to the electrochemical reaction chamber. The housing 320 is also provided with an exhaust hole 323 connected to the electrochemical reaction chamber for exhausting oxygen from the electrochemical reaction chamber.

The liquid line port 131 is connected to the liquid replenishing port. The liquid from the liquid storage space can flow into the liquid replenishing port through the liquid circuit interface 551, the liquid transport pipe 521 and the liquid circuit port 131 in sequence, and then enter the electrochemical reaction chamber to replenish liquid to the electrochemical reaction chamber. In one example, a fluid replenishment pipeline may be connected between the fluid port 131 and the fluid replenishment port.

The air inlet port 132 is connected to the exhaust hole 323 . The oxygen in the electrochemical reaction chamber can flow out through the exhaust hole 323 and flow into the liquid storage space through the air inlet port 132, the air inlet pipeline 522 and the air inlet interface 552, so that the soluble impurities in the oxygen are dissolved in the liquid storage space. of liquid to achieve filtration or purification. In one example, a filter pipeline may be connected between the exhaust hole and the air inlet port 132 . The filter pipeline can be embedded in the foam layer.

In the above embodiment, the inner pot 120 may be a refrigerated inner pot 120 . In one example, the refrigeration and freezing device 10 further includes another inner bladder 150, the interior of which defines another storage compartment 152, such as a variable temperature compartment or a freezing compartment. The filtered oxygen can sequentially flow through the air outlet interface 553, the air outlet pipeline 523 and the air outlet port 133 to another storage compartment 152 to create a high-oxygen fresh-keeping atmosphere. Since the filtered oxygen does not contain electrolyte, the solution of this embodiment can be used to provide clean oxygen to another storage compartment 152 . In one example, an oxygen delivery pipeline may be connected between the air outlet port 133 and another inner bladder 150 . Oxygen pipelines can be embedded in the foam layer.

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

Housing 320 has lateral openings 321 . For example, the housing 320 may be in the shape of a flat rectangular parallelepiped. The lateral opening 321 can be provided 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 provided on the surface of the housing 320 with the largest area.

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

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

The above examples of the electrochemical reaction of the cathode plate 330 and the anode plate 340 are only illustrative. Based on understanding the above embodiments, those skilled in the art should easily change the type of electrochemical reaction, or adapt it to other electrochemical reactions. The structure of the reaction type oxygen treatment device 300 can be expanded, and these transformations and expansions should fall within the protection scope of the present invention.

The refrigeration and freezing device 10 may further include a storage container 600 disposed in the storage compartment 122, and the interior of the storage container 600 defines a storage space. The cathode plate 330 of the oxygen treatment device 300 is in air flow communication with the storage space, 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. At this time, the refrigeration and freezing device 10 may further include a ventilation pipeline embedded in the foam layer. The ventilation pipeline may include a gas collection pipeline and a return gas pipeline.

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

Using the above structure, the gas collection pipeline and the return gas pipeline are used to connect the storage space and the oxygen treatment device 300. The gas with a high oxygen content in the storage space can flow to the cathode plate 330 through the gas collection pipeline, so that the cathode plate 330 can be utilized. Oxygen is used as a reactant for electrochemical reactions to form hypoxic gas with lower oxygen content. These hypoxic gases can be returned to the storage space through the return pipeline, thus reducing the oxygen content in the storage space.

In some optional embodiments, the oxygen treatment device 300 may further include a cover, which is buckled on the side of the housing 320 where the lateral opening 321 is opened, so as to jointly define with the housing 320 the opening that communicates with the cathode plate 330 . airflow space. Under the guidance of the gas collection pipeline, the gas from the storage space flows into the gas flow space and contacts the cathode plate 330, thereby forming oxygen-depleted gas under the action of the cathode plate 330. These oxygen-depleted gases are transported back to the storage space through the return gas pipeline. storage space to create a low-oxygen fresh-keeping atmosphere in the storage space.

A first connection port and a second connection port may be provided on the cover to connect the gas collection pipeline and the air return pipeline respectively.

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

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

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

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

The oxygen treatment device 300 can be fixed in the assembly groove, and the fixing method includes but is not limited to screwing, snapping, riveting, welding, and bonding.

In some optional embodiments, the refrigeration and freezing device 10 has a box body 100, and the box body 100 includes the above-mentioned inner bladder 120. The box body 100 also includes a box shell 170, which is covered on the outside of the foam layer to sandwich the foam layer with the inner bladder 120. The box shell 170 has a back plate, and an assembly groove is formed between the back wall of the inner bladder 120 and the back plate of the box shell 170 . That is to say, the oxygen treatment device 300 of this embodiment is disposed in the foam layer on the back of the inner bladder 120 . The back plate of the box shell 170 can close the opening of the assembly groove to improve the appearance.
