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

Fig. 1 is a schematic block diagram of a refrigeration and freezer 10 according to one embodiment of the utility model. The refrigerating and freezing device 10 according to the embodiment of the present utility model may be a refrigerator, or may be a refrigerator, a freezer or a refrigerating apparatus having a low-temperature storage function, for example. The refrigeration and freezer 10 can generally include a liner 120 and a reservoir 500.

Fig. 2 is a schematic configuration diagram of the liner 120 of the refrigerating and freezing apparatus 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 freezer compartment, or a temperature change compartment, but may be a cryogenic compartment or any other compartment. Preferably, the storage compartment 122 of the present embodiment is a refrigerating compartment. The liner 120 is provided with at least one fluid port 130 extending through a wall thereof.

Fig. 3 is a schematic internal configuration diagram of the refrigerating and freezing apparatus 10 shown in fig. 1. Fig. 4 is a schematic exploded view of the internal structure of the refrigerating and freezing apparatus 10 shown in fig. 3. The liquid storage device 500 is disposed in the storage compartment 122. The liquid storage device 500 includes a liquid storage container 510, and a liquid storage space is defined inside the liquid storage container 510. The liquid storage space is used for storing liquid. The liquid type includes, but is not limited to, water. The liquid stored in the liquid storage space can be set according to the type of the liquid required by the liquid demand end so as to meet the liquid supplementing requirement of the liquid demand end.

The fluid storage container 510 is formed with at least one fluid interface 550 communicating with the fluid storage space, and the fluid interfaces 550 are in one-to-one correspondence with the fluid ports 130, so that the fluid storage space communicates with the external environment of the liner 120. In this embodiment, the fluid ports 130 are also one or more, as are the fluid interfaces 550. The fluid interfaces 550 and the fluid ports 130 are in one-to-one correspondence, that is, when the fluid interfaces 550 and the fluid ports 130 are respectively one, they are in communication with each other, so as to form one fluid delivery channel, and when the fluid interfaces 550 and the fluid ports 130 are respectively multiple, one fluid interface 550 is in corresponding communication with one fluid port 130, so as to form multiple fluid delivery channels. The number of fluid interfaces 550 is the same as the number of fluid ports 130.

Fluid interface 550 and fluid port 130 are used to allow fluid to pass through, respectively. The fluid type includes liquid and/or gas. That is, depending on the fluid delivery channel established between the fluid port 550 and the fluid port 130, the fluid storage space may exchange fluid with the external environment of the inner container 120 or may exchange gas with the external environment of the inner container 120.

By providing at least one fluid port 130 penetrating through the wall surface of the liner 120 and providing at least one fluid port 550 communicating with the liquid storage space of the liquid storage container 510, the fluid ports 550 are communicated with the fluid ports 130 in a one-to-one correspondence manner, so that a fluid barrier between the storage compartment 122 of the refrigeration and freezing device 10 and the external environment is broken, and the liquid storage device 500 arranged in the storage compartment 122 can exchange substances with the external environment. By adopting the solution of the present embodiment, the liquid demand end does not need to be disposed in the storage compartment 122, which avoids the risk of compressing the storage volume and can meet various design requirements of the refrigeration and freezing device 10. The liquid-demand end may be located at any location remote from the storage compartment 122, such as within a foaming layer, within a compressor compartment or within a tunnel, etc.

The fluid interface 550 may be in direct communication with the fluid port 130. When the fluid port 550 is in direct communication with the fluid port 130, the two may be nested within each other in a plugged fashion.

Of course, fluid port 550 and fluid port 130 may also be in indirect communication, such as via tubing. Fig. 5 is a schematic configuration diagram of the storage container 600 and the liquid storage device 500 of the refrigerating and freezing apparatus 10 shown in fig. 4. Fig. 6 is a schematic exploded view of the reservoir 500 of the refrigeration and freezer 10 shown in fig. 5. Fig. 7 is another schematic exploded view of the reservoir 500 of the refrigerated freezer 10 shown in fig. 5. In some alternative embodiments, the fluid storage device 500 further comprises at least one fluid delivery line 520 disposed within the storage compartment 122. Fluid delivery lines 520 are connected one-to-one between fluid interface 550 and corresponding fluid ports 130. The number of fluid transfer lines 520 is the same as the number of fluid ports 130 and fluid interfaces 550.

The fluid delivery pipes 520 are connected one by one between the fluid interfaces 550 and the corresponding fluid ports 130, which means that when the fluid interfaces 550 and the fluid ports 130 are respectively one, one fluid delivery pipe 520 is connected between the fluid interfaces 550 and the fluid ports 130, so as to form one fluid delivery channel, and when the fluid interfaces 550 and the fluid ports 130 are respectively multiple, one fluid delivery pipe 520 is correspondingly connected between the fluid interfaces 550 and the fluid ports 130, so as to form multiple fluid delivery channels.

When the fluid delivery pipeline 520 is disposed between the fluid interface 550 and the fluid port 130, since a regulating device for the flow rate and the flow direction of the fluid can be disposed on the fluid delivery pipeline 520, the solution of the embodiment is adopted to facilitate regulating the fluid exchange process between the fluid storage space and the external environment of the liner 120. The fluid transfer line 520 may be secured within the storage compartment 122. Because the fluid port 550 is not directly connected to the fluid port 130, but is in communication with the fluid delivery line 520, when the fluid delivery line 520 is fixed to the storage compartment 122, it is equivalent to extending the end port of the fluid port 130 into the storage compartment 122, so as to facilitate manual connection.

In some alternative embodiments, the reservoir 500 further includes a mounting cavity 530 that is fixedly mounted within the storage compartment 122. And the fitting chamber 530 is connected with a pipe fitting 540, and the pipe fitting 540 has a hollow cylindrical passage into which the fluid delivery pipe 520 is inserted to achieve a fixed fitting. The conduit fitting 540 may be fixedly coupled to the fitting cavity 530 by a threaded connection.

When the assembly cavity 530 is fixed in the storage compartment 122, the pipe assembly 540 is disposed in the assembly cavity 530, and the fluid conveying pipe 520 is disposed in the hollow cylindrical channel defined by the pipe assembly 540 to realize the fixed assembly of the fluid conveying pipe 520, the structural stability of the fluid conveying structure can be improved, and the leakage problem can be reduced or avoided.

The conduit fitting 540 may be integrally formed within the fitting cavity 530 or fixedly coupled to the fitting cavity 530. The number of hollow cylindrical channels defined by the tubing assembly 540 is one or more and is the same as the number of fluid transfer tubing 520. In one example, the conduit fittings 540 may be at least one, with each conduit fitting 540 defining a hollow cylindrical passage. In another example, each conduit fitting 540 may define two hollow cylindrical channels.

In another example, the tube fitting 540 defines twice the number of hollow cylindrical channels as the number of fluid delivery tubes 520. In a further example, each fluid delivery conduit 520 is provided with a conduit fitting 540 at each end, each conduit fitting 540 defining a hollow cylindrical channel for securing each end of a fluid delivery channel, thereby further improving the structural stability of the fluid delivery structure and reducing or avoiding leakage of fluid due to loosening of the connection between the conduit orifices. At least a portion of the conduit fitting 540 is fixedly disposed within the fitting cavity 530; of course, there may be another portion of the tubing assembly 540 disposed outside of the assembly cavity 530 to facilitate securing the end of the fluid delivery tubing 520.

In one example, the fluid delivery line 520 extends in a horizontal direction from front to back. The first assembly portion and the second assembly portion of the pipe assembly 540, where the first assembly portion is fixedly connected to the assembly cavity or is an integral piece with the assembly cavity, and defines a concave arc plate that is concave downward and is arc-shaped. The concave arc plate is used as the lower channel wall of the hollow cylindrical channel. The second fitting portion defines an upwardly concave arcuate plate recessed upwardly and arcuate as an upper channel wall of the hollow cylindrical channel. The upper channel wall and the lower channel wall together define a complete hollow cylindrical channel for insertion of the fluid transfer tubing 520 therein for a secure assembly.

The second fitting portion is detachably fitted over the first fitting portion. The second fitting portion also defines a first threaded bore on either side of the upper passageway wall. The second fitting portions are respectively formed with second screw holes located on both sides of the lower passage wall and in one-to-one correspondence with the first screw holes, so as to achieve detachable fitting by screwing.

A fluid delivery line 520 may extend through the mounting cavity 530 to communicate the fluid port 130 with the fluid interface 550. The liquid storage device 500 may further include a packaging cover 541 covering the top of the assembly cavity 530, so as to protect the pipeline and prevent dust.

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

The container cover 580 is formed with outwardly protruding claws. The edges of the opening 512 of the reservoir 510 may be provided with a snap-fit groove into which the jaws are inserted. When the cover 580 is placed over the opening 512 and the jaws are snapped into the snap-fit slots, this indicates that the cover 580 is in place and the opening 512 can be closed.

In some alternative embodiments, fluid port 130 is a hollow cylindrical interface formed on bladder 120 and raised toward a corresponding fluid interface 550 to nest and removably connect with a first end of fluid delivery line 520. The fluid port 550 is a hollow cylindrical port formed on the reservoir 510 and rising toward the corresponding fluid port 130 to nest and detachably connect with the second end of the fluid delivery line 520.

That is, the fluid ports 130 and fluid interfaces 550 may each be nested with respect to the fluid delivery line 520 to effect connection, and may each be de-nested with respect to the fluid delivery line 520 to effect disconnection.

Of course, the fluid ports 130 may also further bulge in a direction away from the corresponding fluid ports 550 to nest and detachably connect with tubing disposed outside of the bladder 120.

When the fluid port 130 and the fluid port 550 are hollow cylindrical ports, respectively, and are nested with and detachably disposed at the ends of the fluid conveying pipeline 520, the fluid port 130 and the fluid port 550 can be connected into a smooth fluid conveying channel in an inserting manner, which is beneficial to simplifying the assembly process of the fluid conveying structure and reducing the manufacturing cost of the whole machine.

In some alternative embodiments, the fluid port 130 includes a fluid path port 131 for circulating a liquid. The fluid interface 550 includes a fluid path interface 551 for circulating a liquid. The fluid delivery line 520 includes a liquid delivery line 521 connected between the liquid port 131 and the liquid port 551.

At this time, the liquid in the liquid storage space can flow through the liquid channel connector 551, the liquid delivery pipeline 521 and the liquid channel port 131 in sequence and flow out of the storage compartment 122, so as to flow into the liquid demand end arranged outside the storage compartment 122, thereby replenishing the liquid demand end with liquid and keeping the liquid demand end working.

Of course, in another example, liquid from the environment outside the liner 120 may also flow into the liquid storage space via the liquid path port 131, the liquid delivery line 521, and the liquid path port 551, thereby replenishing the storage box with liquid.

In some further embodiments, the fluid port 130 further comprises at least one gas path port for a fluid gas. The fluid interface 550 also includes at least one gas circuit interface for circulating gas and in one-to-one communication with the gas circuit ports. The fluid delivery lines 520 further include at least one gas delivery line connected one-to-one between a gas path port and a corresponding gas path port.

That is, the gas path ports may be one or more. The air path interface can also be one or more. The gas conveying pipelines are connected between the gas circuit interfaces and the corresponding gas circuit ports one by one, namely, when the gas circuit interfaces and the gas circuit ports are respectively one, one gas conveying pipeline is connected between the gas circuit interfaces and the gas circuit ports, so that one gas conveying channel is formed, and when the gas circuit interfaces and the gas circuit ports are respectively multiple, one gas conveying pipeline is correspondingly connected between one gas circuit interface and one gas circuit port, so that multiple gas conveying channels are formed.

In one example, when the gas path port, the gas path interface, and the gas delivery line are respectively one, gas from the environment outside the liner 120 may flow into the liquid storage space via the gas path port, the gas delivery line, and the gas path interface to filter the soluble impurities. The filtered gas may now be exhausted into the storage compartment 122.

In another example, when the gas path port, the gas path interface, and the gas delivery line are respectively plural, the gas from the environment outside the liner 120 may flow into the liquid storage space via one gas delivery channel to filter the soluble impurities. The filtered gas can flow to the external environment of the liner 120 for use through another gas delivery channel.

In some alternative embodiments, the number of gas circuit interfaces is two, inlet interface 552 and outlet interface 553, respectively. The number of the air path ports is two, 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.

The two gas delivery pipelines are respectively 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 for guiding the gas from the external environment of the liner 120 to the liquid storage space to filter the soluble impurities, and the air outlet pipeline 523 is connected between the air outlet interface 553 and the air outlet port 133 and is used for discharging the filtered gas to the external environment of the liner 120.

By adopting the above scheme, the liquid storage device 500 can supply liquid to the liquid demand end arranged outside the liner 120, and can filter out soluble impurities in the gas from the external environment of the liner 120, so as to provide clean gas to the external environment (such as the gas demand end) of the liner 120, thereby meeting the air conditioning requirement.

In some alternative embodiments, the liquid path interface 551 is lower than the gas path interface. The fluid path port 131 is lower than the gas path port. And the fluid path port 131 is opposite to the fluid path port 551.

That is, the liquid path interface 551 is disposed below the gas path interface. In one example, the fluid path interface 551 is disposed in a bottom section of the fluid reservoir 510. The air path interface is disposed at the top section of the reservoir 510. The liquid in the liquid storage space can automatically flow out of the liquid channel connector 551 under the action of gravity and flow into the liquid delivery pipeline 521, and then flow out of the liner 120 and into the liquid demand end. The gas to be filtered from the external environment of the inner container 120 can flow into the liquid storage space under the guidance of the gas path interface, and flow downwards in the liquid storage space before flowing upwards, so as to prolong the flow path, and make the soluble impurities fully dissolve in the liquid stored in the liquid storage space.

In some alternative embodiments, the fluid reservoir device 500 further comprises a power mechanism disposed at the fluid path interface 551 or in the fluid path between the fluid path interface 551 and the fluid path port 131 for pressurizing fluid flowing from the fluid path interface 551 to the fluid path port 131.

In one example, the power mechanism is a pump. In another example, the power mechanism may also be provided as other types of power machine components, such as a supercharger, etc. In one example, a power mechanism may be provided on the fluid delivery line 521 for facilitating the accelerated flow of fluid from the fluid port 551 to the fluid port 131, thereby improving the fluid replacement efficiency of the fluid reservoir 500. Of course, the power mechanism may be disposed at the fluid path port 131.

In some alternative embodiments, the reservoir 500 further includes a one-way valve 570 disposed at the intake port 552 or in the flow path between the intake port 132 and the intake port 552, for example, may be disposed on the intake conduit 522 for allowing one-way passage of fluid from the intake port 132, thereby acting as a suck-back prevention. Of course, the check valve 570 may also be disposed at the intake port 132.

In the above embodiment, the liner 120 may be integrally injection molded. In other alternative embodiments, the bladder 120 may include two distinct portions. For example, the bladder 120 may include a body portion 125 and a securing plate 126. Fig. 8 is a schematic exploded view of the liner 120 of the refrigeration and freezer 10 shown in fig. 2. The body portion 125 has a notch 125a. The fixing plate 126 closes the notch 125a to define the liner 120 together with the body 125 and forms a part of the wall of the liner 120. The retaining plate 126 defines a fluid port 130.

The body portion 125 and the fixing plate 126 may be independently molded through an injection molding process. Because the fluid port 130 is disposed on the fixing plate 126, it is not necessary to form the fluid port 130 on the body 125, and therefore, by adopting the solution of this embodiment, the forming process of the liner 120 can be simplified, and the operation difficulty of the forming process can be reduced.

The body portion 125 may define a main body profile of the liner 120. The fixing plate 126 may cover the notch 125a and be fixedly connected with the main body portion to close the notch 125a, thereby defining the complete liner 120 with the main body portion 125.

The edge of the fixing plate 126 is provided with a positioning structure. The fixing plate 126 may be fastened to the inner container 120 by a positioning mechanism in advance before the inner container 120 is foamed. After the bladder 120 is foamed, the fluid ports 130 may be connected to the first ends of the fluid delivery lines 520 one by one, and then the reservoir may be mounted to the storage compartment 122 such that the fluid ports 550 are connected to the second ends of the fluid delivery lines 520 one by one. The pipeline butt joint process can be completed in one step, and separate intubation is not needed.

In some alternative embodiments, the retaining plate 126 forms a portion of the rear wall of the bladder 120. The liquid storage container 510 is disposed at the front side of the fixing plate 126 and spaced apart from the rear wall of the inner container 120 to define an installation space for assembling a pipe (e.g., the fluid delivery pipe 520). The installation space may be used to install at least a portion of the assembly cavity 530. A conduit fitting 540 and a fluid transfer conduit 520 may be further disposed within the installation space.

In one example, the mounting cavity 530 is fixedly coupled to the plate-like connector. The plate-like connector is fixedly coupled to the wall of the inner container 120 such that the assembly cavity 530 is fixed in the storage compartment 122. In one example, the plate-shaped connector has a socket portion that is socket-connected to the inner surface of the sidewall of the inner container 120, and a screw portion that is screw-connected to the inner surface of the sidewall of the inner container 120. In one example, the plate connector also has a locating post that is inserted into a sidewall recess of the inner container 120 to achieve positioning.

The outer surface of the bottom wall of the liquid storage container 510 is provided with a limiting rib protruding outwards. The upper surface of the bottom wall of the storage compartment 122 is provided with a limiting groove into which a limiting rib is inserted to realize positioning.

In some alternative embodiments, the retaining plate 126 defines a fluid port 130, and the fluid port 130 may be an optical aperture. The fluid delivery lines 520 may be plugged one-to-one into the corresponding fluid ports 130. Fig. 9 is a schematic internal structural view of a refrigerating and freezing apparatus 10 according to an embodiment of the present utility model. Fig. 10 is a schematic exploded view of the internal structure of the refrigerating and freezing apparatus 10 shown in fig. 9. The inner container 120 may be further provided with a connection plate 127 fixedly connected to the inner container 120 and defining connection ports in one-to-one correspondence with the fluid ports 130. The connection plate 127 is formed with a recess recessed toward a direction away from the fixing plate 126, and a bottom of the recess bulges outward toward the direction away from the fixing plate 126 to form a connection port communicating with an external space. Fluid delivery line 520 is inserted into the recess to effect the connection. By adopting the scheme of the embodiment, the connecting plate 127 can be communicated with a plurality of fluid conveying pipelines 520 at one time, so that the intubation step is simplified.

In some alternative embodiments, the reservoir 500 further comprises a fluid guide mechanism 590. The reservoir 510 has an opening 512. Fig. 11 is a schematic block diagram of the reservoir cap 580 and the fluid guide mechanism 590 of the reservoir 500 according to one embodiment of the utility model.

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

The fluid guide mechanism 590 is fixedly coupled to the cover 580 or is integrally formed with the cover 580 and is inserted into the liquid storage space when the cover 580 covers the opening 512 to define a guide passage for guiding the flow of fluid. The guide channel defines a flow path of the fluid in the liquid storage space. Under the action of the fluid guiding mechanism 590, the fluid flowing into the liquid storage space can flow along the fluid flow path defined by the guiding channel, so as to reduce or avoid disordered diffusion of the fluid.

Since the fluid guide mechanism 590 is fixedly coupled to the cover 580 or is integrally formed with the cover 580, the fluid guide mechanism 590 can be moved synchronously with the cover 580 for insertion into the reservoir space when the cover 580 covers the opening 512. When the fluid guiding mechanism 590 is fixedly connected to the cover 580, the fluid guiding mechanism 590 may be connected to the cover 580 by fastening, screwing, bonding, riveting, welding, or the like. When the fluid guide 590 is integrally formed with the cover 580, the fluid guide 590 may be integrally formed with the cover 580 by an injection molding process.

By fixedly connecting the fluid guiding mechanism 590 with the container cover 580 or forming the fluid guiding mechanism 590 and the container cover 580 as one piece, and inserting the fluid guiding mechanism 590 into the liquid storage space when the opening 512 of the liquid storage container 510 of the container cover 580 is formed, a guiding channel for guiding the fluid flow is defined, and the fluid guiding mechanism 590 does not need to be fixedly assembled in the liquid storage space, so that the assembly mode of the fluid guiding mechanism 590 of the liquid storage device 500 can be optimized and the assembly process can be simplified by adopting the scheme of the embodiment.

The fluid guide 590 defines a guide channel that communicates with the external environment of the reservoir 510 to allow fluid from the external environment to flow through the reservoir space under the direction of the guide channel. The fluid may be a gas or a liquid.

When the fluid is gas, the fluid can flow along a relatively fixed path and flow out of the liquid storage space under the action of the guide channel defined by the fluid guide mechanism 590, so as to ensure the gas washing efficiency. When the fluid is liquid, the fluid can flow to the designated portion of the liquid storage space under the action of the guide channel defined by the fluid guide mechanism 590, so as to meet the liquid supplementing requirement and/or the liquid quality adjusting requirement of the liquid storage space.

Fig. 12 is a schematic exploded view of the reservoir 510 and the reservoir cap 580 of the reservoir device 500 and the fluid guide mechanism 590, according to one embodiment of the present utility model. In some alternative embodiments, the guide channels include an inlet channel 591a and an outlet channel 592a, each communicating with an external environment of the reservoir space, such that gas from the external environment flows into the reservoir space through the inlet channel 591a and out of the reservoir space through the outlet channel 592a, and filters soluble impurities as they flow to the outlet channel 592 a.

Fig. 13 is a schematic perspective view of an assembled structure of the liquid storage container 510 and the container cover 580 of the liquid storage device 500 shown in fig. 12, and the fluid guide mechanism 590. The inlet passage 591a may communicate with the outlet passage 592a, such as directly or indirectly. In one example, the inlet channel 591a is in indirect communication with the outlet channel 592 a. For example, the inlet passage 591a and the outlet passage 592a may communicate with each other through the liquid stored in the liquid storage space. The gas flowing into the liquid storage space from the gas inlet channel 591a may flow through the liquid stored in the liquid storage space, and then flow out of the liquid storage space through the gas outlet channel 592a, so that the soluble impurities in the gas are dissolved in the liquid stored in the liquid storage space when flowing into the gas outlet channel 592 a.

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

The reservoir cap 580 and the fluid guide mechanism 590 may be integrally formed by an injection molding process as a single piece. With the above-described configuration, since the gas inlet passage 591a and the gas outlet passage 592a may be directly formed in the container cover 580 and may be used to guide the flow of the gas in the liquid storage space, the gas may flow through the liquid storage space along a predetermined path, and may hardly flow irregularly, which is advantageous for improving the recovery amount of the filtered gas.

In some alternative embodiments, the vessel lid 580 is provided with an inlet port 552 and an outlet port 553. Wherein intake interface 552 communicates with intake passage 591a, configured to allow gas from the external environment to flow into intake passage 591a. The outlet interface 553 communicates with the outlet channel 592a and is configured to allow filtered gas to flow out of the outlet channel 592a. The air inlet interface 552 and the air outlet interface 553 may be formed into the cover 580 by an injection molding process. In one example, inlet channel 591a communicates directly with inlet interface 552 and outlet channel 592a communicates directly with outlet interface 553.

Through set up inlet connection 552 and outlet connection 553 on container lid 580, inlet connection 552 and outlet connection 553 can be connected with the pipeline of outside, and the gas that waits to filter from the external environment of stock solution space can be carried to the stock solution space through the pipeline, and the gas after filtering also can be carried to appointed space through the pipeline to make gas can directional flow.

The air inlet interface 552 and the air outlet interface 553 may be hollow cylindrical interfaces formed on the cover 580 and protruding to the outside of the liquid storage space, respectively, to facilitate the connection with the external pipeline.

In a further example, the air inlet interface 552, the air outlet interface 553, and the fluid guide mechanism 590 are all molded onto the reservoir cap 580 by an injection molding process to form an integral piece, so that the related operations related to connection and fixation can be omitted, and the assembly of the fluid delivery structure can be completed simply by covering the reservoir cap 580 at the opening 512 of the reservoir 510.

Of course, in another example, the inlet interface 552, the outlet interface 553, and/or the fluid guide mechanism 590 may also be fixedly coupled to the cover 580. The fixing connection mode comprises but is not limited to screwing, clamping, bonding, welding or riveting and the like.

In some alternative embodiments, fluid directing mechanism 590 includes a filter tube 591 and an outlet tube 592. Wherein the air filter tube 591 communicates with the air inlet port 552 and extends from the inner surface of the tank cover 580 toward the liquid storage space to define an air inlet passage 591a.

The outlet duct 592 communicates with the outlet port 553 and extends from the inner surface of the container cover 580 toward the liquid storage space to define an outlet channel 592a. The depth of the air outlet pipe 592 in the liquid storage space is higher than the depth of the air filtering pipe 591 in the liquid storage space. That is, the length of the outlet tube 592 is shorter than the length of the filter tube 591. In one example, the air filter tube 591 may extend to a bottom section of the liquid storage space and the air outlet tube 592 may extend to a top section of the liquid storage space. The filter tube 591 and the outlet tube 592 may be straight tubes, respectively.

By adopting the scheme, the gas to be filtered can reach the bottom section of the liquid storage space under the guidance of the gas filtering pipe 591, and moves downwards in the liquid storage space, and then moves upwards, so that the soluble impurities in the gas are dissolved in the liquid stored in the liquid storage space, and the gas purification is completed. The purified gas can flow to the vicinity of the air outlet pipe 592 in a concentrated manner 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 that of the air filtering pipe 591 in the liquid storage space, the path of upward movement of the air can be prolonged, so that the soluble impurities in the air are fully dissolved in the liquid stored in the liquid storage space.

In some alternative embodiments, the fluid directing mechanism 590 further comprises an air path blocking portion 595 extending from the inner surface of the vessel cover 580 toward the reservoir space and separating the reservoir space from the air path blocked air filtering zone 515 and the air non-filtering zone 516. Wherein the method comprises the steps of

The air filtering section 515 communicates with the air inlet passage 591a and the air outlet passage 592a and is configured to allow air from the external environment to flow therethrough for filtering. That is, the air filtering section 515 is in air-flow communication with the air inlet passage 591a and the air outlet passage 592a, and the air flowing into the liquid storage space through the air inlet passage 591a may flow through the air filtering section 515 and, after flowing through the air filtering section 515, flow into the air outlet passage 592a. A filter tube 591 and an outlet tube 592 may be inserted into the filter region 515.

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

The air path blocking portion 595 separates the air path blocking air filtering area 515 from the non-air filtering area 516 in the air storage space, and the air path blocking portion 595 blocks the air flow path between the air filtering area 515 and the non-air filtering area 516, so that the air flowing through the air filtering area 515 cannot enter the non-air filtering area 516. That is, the gas flowing into the liquid storage space through the gas inlet passage 591a can flow only in the air filtering area 515.

With the above configuration, the air passage blocking portion 595 is provided in the liquid storage device 500, and the air passage blocking portion 595 is used to separate the liquid storage space into the air passage blocked air filtering area 515 and the non-air filtering area 516, so that the function of purifying the air can be performed only in the air filtering area 515. Because the air filtering area 515 is only a subspace of the liquid storage space, and the air path between the air filtering area 515 and other areas of the liquid storage space is blocked, the air from the external environment of the liquid storage space can only flow in the air filtering area 515, and can not freely diffuse to the non-air filtering area 516, so that the liquid storage device 500 of the embodiment has a higher purified air release rate.

In some alternative embodiments, the non-air-filtration zone 516 is configured to receive liquid from outside the liquid storage space. For example, the reservoir cap 580 may be provided with a fill port 587 in communication with the non-air filtering section 516 to allow external liquid to flow into the non-air filtering section 516 through the fill port 587. A movable sub-cap 586 is provided at the filling port 587 to open or close the 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 or the liquid discharge process performed in the non-gas filtering area 516 may be performed at the same time, and do not interfere with each other.

The air path blocking portion 595 blocks a part of the liquid path between the air filtering area 515 and the non-air filtering area 516, so that the air filtering area 515 and the non-air filtering area 516 keep the liquid path communicated in the case of air path blocking. That is, the gas path blocking portion 595 blocks only the gas path between the gas filtering area 515 and the non-gas filtering area 516, but does not block the liquid path between the gas filtering area 515 and the non-gas filtering area 516.

When the non-air filtering area 516 is configured to receive the liquid from the outside of the liquid storage space, and the air channel blocking portion 595 blocks a portion of the liquid channel between the air filtering area 515 and the non-air filtering area 516, so that the air channel between the air filtering area 515 and the non-air filtering area 516 is kept in communication under the condition that the air channel is blocked, a liquid level difference generated between the air filtering area 515 and the non-air filtering area 516 of the liquid storage device 500 can be reduced or avoided, and the liquid amount of the air filtering area 515 can be conveniently regulated.

Based on the above structure, the air filtering area 515 and the non-air filtering area 516 can always keep the same liquid level, and liquid exchange can be smoothly performed between the two areas. In this way, the liquid in the air filtering area 515 can remain in a flowing state to some extent without periodic replacement. Also, material dissolved in the gas filtering section 515 may enter the non-gas filtering section 516 and flow back into the environment of use, such as the oxygen treatment device 300 described below, to be recycled.

In some alternative embodiments, the opening 512 of the reservoir 510 is disposed at the top of the reservoir 510. The air path blocking part 595 is a partition plate-like structure located between the air filtering area 515 and the non-air filtering area 516 and extending downward from the lower surface of the container cover 580 and forming a gap with the upper surface of the bottom wall of the liquid storage container 510, so that the air filtering area 515 is in liquid communication with the non-air filtering area 516. The air path blocking part 595 of the barrier-like structure may be a vertical plate.

This gap serves as a window for liquid exchange between the filtered region 515 and the unfiltered region 516. The bottom end of the air filter tube 591 is higher than the bottom end of the air channel blocking portion 595, and the distance between the air filter tube 591 and the bottom end of the air channel blocking portion 595 is greater than a preset threshold value. The preset threshold may be determined according to a displacement of the gas flowing into the liquid storage space from the gas filter tube 591 for downward movement in the liquid storage space, for example, the preset threshold may be greater than or equal to a displacement of the gas for downward movement in the liquid storage space.

In some alternative embodiments, the reservoir 510 has a fluid path interface 551 in communication with the reservoir space configured to allow fluid out of the reservoir space. And the liquid path interface 551 is disposed in the bottom section of the liquid storage container 510. In one example, the liquid path interface 551 may communicate with the non-filtered region 516 to allow liquid within the non-filtered region 516 to flow out of the liquid outlet space through the liquid path interface 551 and into a use environment, such as the oxygen treatment device 300 described below. Of course, in another example, the fluid path interface 551 may also be in communication with the air filtering section 515 to allow fluid within the air filtering section 515 to exit the fluid outlet space via the fluid path interface 551 and flow into a use environment, such as the oxygen treatment device 300 described below.

In one example, air inlet interface 552 and air outlet interface 553 may each be hollow cylindrical interfaces and extend in a horizontal direction, e.g., may extend front-to-back. The filter tube 591 and the outlet tube 592 may each be a hollow straight tube and extend from top to bottom.

In some alternative embodiments, the liquid storage device 500 may further include a liquid level sensor disposed in the liquid storage space for detecting a liquid level in the liquid storage space, and the refrigerating and freezing device 10 may send an alarm to prompt a user to supplement or stop supplementing the liquid in the liquid storage space when the liquid level in the liquid storage space exceeds a preset range.

Fig. 14 is a schematic configuration view of an oxygen treatment device 300 of the refrigerating and freezing apparatus 10 according to an embodiment of the present utility model. Fig. 15 is a schematic exploded view of the oxygen treatment device 300 of the refrigeration and freezer 10 shown in fig. 14. In some alternative embodiments, the refrigerated chiller 10 also includes an oxygen treatment device 300. The oxygen treatment device 300 has a housing 320 and an electrode pair, wherein an electrochemical reaction chamber for containing an electrolyte is defined inside the housing 320, and the electrode pair is disposed in the electrochemical reaction chamber and is used for transferring external oxygen to the electrochemical reaction chamber through an electrochemical reaction. The electrochemical reaction bin is used as a liquid demand end.

The housing 320 is provided with a fluid-replenishing port 322 which communicates with the electrochemical reaction chamber. The casing 320 is further provided with an exhaust hole 323 communicated with the electrochemical reaction chamber for exhausting oxygen in the electrochemical reaction chamber.

The liquid path port 131 communicates with the liquid replenishing port. Liquid from the liquid storage space can flow through the liquid path interface 551, the liquid conveying pipeline 521 and the liquid path port 131 in sequence into the liquid supplementing port so as to enter the electrochemical reaction bin to supplement liquid to the electrochemical reaction bin. In one example, a make-up line may be connected between the fluid line port 131 and the make-up port.

The intake port 132 communicates with the exhaust hole 323. The oxygen in the electrochemical reaction chamber can flow out through the exhaust hole 323 and sequentially flows through the air inlet port 132, the air inlet pipeline 522 and the air inlet interface 552 to flow into the liquid storage space, so that the soluble impurities in the oxygen are dissolved in the liquid stored in the liquid storage space to realize filtration or purification. In one example, a filter line may be connected between the vent and the intake port 132. The filtering pipeline can be pre-buried in the foaming layer.

In the above embodiments, the liner 120 may be a refrigeration liner 120. In one example, the refrigeration and freezing device 10 further includes another liner 150 defining another storage compartment 152, such as a temperature change compartment or a freezing compartment, therein. The filtered oxygen can flow through the air outlet interface 553, the air outlet pipeline 523 and the air outlet port 133 to the other storage compartment 152 in order 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 the other storage compartment 152. In one example, an oxygen delivery line may be connected between the outlet port 133 and the other liner 150. The oxygen delivery pipeline can be pre-buried in the foaming layer.

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

The housing 320 has a lateral opening 321. For example, the housing 320 may have a flat rectangular parallelepiped shape. The lateral opening 321 may be provided on any face of the housing 320, such as a top face, a bottom face, or a side face. In one example, the lateral opening 321 may be disposed on a face of the housing 320 where the area is greatest.

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

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

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

The refrigeration and freezing apparatus 10 may further include a storage container 600 disposed in the storage compartment 122, and an interior of the storage container 600 defines a storage space. The cathode plate 330 of the oxygen treatment device 300 is in gas flow communication with the storage space, thereby reducing the oxygen content of the storage space by an electrochemical reaction.

In one example, the oxygen treatment device 300 may be disposed within a foaming layer. In this case, the refrigerating and freezing apparatus 10 may further include a ventilation line pre-buried in the foaming layer. The ventilation lines may include a gas collection line and a return line.

The gas collecting pipeline is used for guiding the gas flowing through the cathode plate 330 to the cathode plate 330, and the gas returning pipeline is used for guiding the gas flowing through the cathode plate 330 back to the storage space so as to reduce the oxygen content of the storage space. For example, the liner wall of the liner 120 is provided with a first ventilation opening communicating with the first end of the gas collecting pipe and a second ventilation opening communicating with the first end of the return gas pipe. Each ventilation opening is an opening formed in the liner wall of the liner 120. The second end of the gas collecting pipe and the second end of the gas returning pipe may be respectively connected to two ends of the cathode plate 330, specifically, the second end of the gas collecting pipe may be connected to an upwind side of the cathode plate 330, and the second end of the gas returning pipe may be connected to a downwind side of the cathode plate 330, so that gas flowing out of the gas collecting pipe may flow into the gas returning pipe after flowing through the cathode plate 330.

By adopting the structure, the gas collecting pipeline and the air return pipeline are utilized to communicate the storage space with the oxygen treatment device 300, and the gas with higher oxygen content in the storage space can flow to the cathode plate 330 through the gas collecting pipeline, so that the cathode plate 330 can perform electrochemical reaction by taking the oxygen in the gas as a reactant to form low-oxygen gas with lower oxygen content, and the low-oxygen gas can return to the storage space through the air return pipeline, thereby playing the role of reducing the oxygen content in the storage space.

In some alternative embodiments, oxygen treatment device 300 may further include a housing that is fastened to a side of housing 320 that is provided with lateral opening 321 to define, with housing 320, a gas flow space that communicates with cathode plate 330. Under the guidance of the gas collecting pipeline, the gas from the storage space flows into the gas flow space and contacts with the cathode plate 330, so that oxygen-deficient gas is formed under the action of the cathode plate 330, and is conveyed back to the storage space through the gas return pipeline, so that the storage space creates a low-oxygen fresh-keeping atmosphere.

The housing can be provided with a first connecting port and a second connecting port which are respectively communicated with the gas collecting pipeline and the gas return pipeline.

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

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

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

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

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

In some alternative embodiments, the refrigerator-freezer 10 has a cabinet 100, the cabinet 100 including the liner 120 described above. The case 100 further includes a case 170 covering the outer side of the foaming layer to clamp the foaming layer with the liner 120. The case 170 has a back plate, and an assembly groove is formed between the back wall of the liner 120 and the back plate of the case 170. That is, the oxygen treatment device 300 of the present embodiment is disposed in the foaming layer at the back of the liner 120. The back plate of the case 170 may close the opening of the fitting groove to make the external appearance beautiful.

In one example, the back plate of the case 170 may be provided with a mounting hole facing the mounting groove, and the oxygen treatment device 300 may be directly fixed into the mounting groove through the mounting hole without disassembling the back plate of the case 170 during the assembly.
