Detailed Description

FIG. 1 is a schematic block diagram of an electrolytic oxygen removal device 10 according to one embodiment of the present invention. The electrolytic oxygen removing device 10 of the present embodiment is used for being installed on the refrigerator 1 and for consuming oxygen in the storage space of the refrigerator 1 through electrochemical reaction, thereby helping the refrigerator 1 to create a low oxygen fresh-keeping atmosphere.

The electrolytic oxygen removal device 10 may generally include an electrolytic oxygen removal assembly 100 and a housing 200.

Wherein the electrolytic oxygen removal assembly 100 is configured to undergo an electrochemical reaction to consume oxygen under an electrolytic voltage. The electrolytic oxygen removal assembly 100 may include a plurality of electrochemical reaction elements for performing an electrochemical reaction. The electrochemical reaction may refer to any electrochemical reaction in which oxygen is the reactant, and may be, for example, a reaction in which water is electrolyzed.

Fig. 1 is a perspective view of an electrolytic oxygen removal device 10. The interior of the housing 200 defines a reaction space 210 and a liquid storage space 220. Wherein the reaction space 210 is used to assemble the electrolytic oxygen removal assembly 100, i.e., the electrolytic oxygen removal assembly 100 is assembled to the reaction space 210 such that the reaction space 210 serves as a site for an electrochemical reaction. The liquid storage space 220 is used for containing liquid and is communicated with the reaction space 210 to supplement liquid to the reaction space 210. The type of liquid contained in the liquid storage space 220 may be determined according to the type of electrochemical reaction, and is generally consumed by the electrochemical reaction. For example, when the electrochemical reaction is a reaction of electrolyzing water, the liquid contained in the liquid storage space 220 is water.

By defining the reaction space 210 and the liquid storage space 220 in the housing 200 of the electrolytic oxygen removing device 10, and installing the power distribution oxygen removing assembly 100 in the reaction space 210 and communicating the liquid storage space 220 with the reaction space 210, the liquid storage space 220 of the electrolytic oxygen removing device 10 can be utilized to supplement liquid to the reaction space 210, so that the electrolytic oxygen removing device 10 has a liquid supplementing function.

Because the reaction space 210 and the liquid storage space 220 are integrated in the housing 200, an integrated liquid supplementing-consuming structure is formed, which greatly simplifies the structure of the whole device, reduces the number of necessary components, and for example, can omit a pipeline structure for communicating the liquid storage space 220 with the reaction space 210. And since the fluid replacement process can be performed inside the case 200, it is advantageous to improve the safety of the fluid replacement process.

By temporarily storing a specific amount of liquid in the liquid storage space 220, the liquid supplementing requirement of the electrolytic oxygen removing assembly 100 can be met within a certain range, and the problem that the electrolytic oxygen removing assembly 100 cannot work normally due to insufficient electrolyte is reduced or avoided, which is beneficial to improving the working performance of the electrolytic oxygen removing assembly 100.

Because the reaction space 210 and the liquid storage space 220 form an integrated liquid supplementing-consuming structure, the shell 200 with a specific space layout structure can be obtained through a forming process, the process is simple, compared with a split liquid supplementing structure, the complex assembly process is omitted, and the sealed communication between the reaction space 210 and the liquid storage space 220 is ensured.

Fig. 2 is a schematic structural view of a housing 200 of the electrolytic oxygen removal device 10 shown in fig. 1.

In some alternative embodiments, the electrolytic oxygen removing device 10 may further include a first partition 400 provided inside the housing 200 to partition the reaction space 210 and the liquid storage space 220 inside the housing 200. For example, the first separator 400 may be a partition plate, which may be formed inside the case 200 by a molding process.

The first partition 400 is provided with a first communication port 410 for communicating the reaction space 210 with the liquid storage space 220. The liquid in the liquid storage space 220 may flow into the reaction space 210 through the first communication port 410 to replenish the reaction space 210 with liquid.

The electrolytic oxygen removing device 10 of the present embodiment has the advantage of exquisite structure by providing the first communication port 410 on the first partition 400, which can communicate the liquid storage space 220 with the reaction space 210.

In some alternative embodiments, the first partition 400 is vertically disposed such that the reaction space 210 is horizontally side by side with the liquid storage space 220. The first communication port 410 is located at the bottom section of the first partition 400, which allows the liquid in the liquid storage space 220 to flow through the first communication port 410 by its own weight and into the reaction space 210. The liquid replenishing process can be automatically performed without applying a driving force to the reaction space 210 from the liquid storage space 220 by a driving module such as a pump.

It should be noted that terms indicating directions or positional relationships such as "vertical", "horizontal", and the like are based on directions or positional relationships in a use state, and are merely for convenience of description, and do not indicate or imply that the described devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the invention.

In some alternative embodiments, the housing 200 is provided with a fluid-filling port 202, and the fluid-filling port 202 communicates between the fluid-storage space 220 and the external environment of the housing 200, so as to allow the fluid from the external environment of the housing 200 to flow into the fluid-storage space 220. The refill port 202 may be located at the top of the housing 200, for example, on a top wall for enclosing the reservoir 220. In some alternative embodiments, the fluid refill port 202 may also be located inside the housing 200, and the interior of the housing 200 is formed with a buffer zone that communicates the fluid refill port 202 with the environment external to the housing 200.

Since the fluid-filling port 202 is formed on the housing 200, the fluid-filling port 202 communicates the fluid-storage space 220 with the external environment of the housing 200, when the fluid-storage volume in the fluid-storage space 220 is reduced, fluid can be filled into the fluid-storage space 220 from the outside of the housing 200, which enables the fluid-storage space 220 to continuously supply electrolyte to the reaction space 210, thereby keeping the fluid level in the reaction space 210 of the electrolytic oxygen-removing device 10 at a higher level all the time.

Fig. 3 is a schematic structural view of an electrolytic oxygen removal device 10 according to another embodiment of the present invention.

In some alternative embodiments, the electrolytic oxygen removing device 10 may further include a fluid-supplementing container 500, in which a fluid-supplementing space 510 for storing fluid is formed, and a fluid-supplying port 520 is formed on the fluid-supplementing container 500 and is used for communicating with the fluid-supplementing port 202 of the housing 200 to supplement fluid to the fluid-storing space 220. That is, the electrolytic oxygen removing device 10 of the present embodiment has another "liquid supply portion", that is, the liquid replenishing container 500, in addition to the "liquid supply portion" of the liquid storage space 220.

The fluid replacement vessel 500 serves as a "further fluid supply portion" of the reaction space 210, and by directly supplementing fluid to the fluid storage space 220, the fluid volume in the fluid storage space 220 can be ensured to be sufficient, thereby meeting the fluid replacement requirement of the reaction space 210.

By constructing the dual liquid supply part by using the liquid replenishing container 500 and the liquid storage space 220, the liquid storage capacity of the electrolytic oxygen removing device 10 can be improved, and meanwhile, the manual direct liquid filling of the liquid storage space 220 can be avoided. If the liquid storage space 220 is directly filled with liquid, the casing 200 needs to be disassembled, and the disassembly process may contact with the electrolyte, so that the safety coefficient is low.

The fluid supply port 520 of the fluid replacement container 500 and the fluid replacement port 202 of the housing 200 may be connected by an infusion line.

In some alternative embodiments, the electrolytic oxygen removal device 10 may further include a fluid level switch 300 having a switch body 320 disposed within the fluid storage space 220 and disposed in correspondence with the fluid replenishment port 202 for movement according to the fluid level within the fluid storage space 220 to open or close the fluid replenishment port 202.

For example, the switch body 320 may open the fluid refill port 202 when the fluid level in the fluid reservoir space 220 falls below a preset fluid level value, such that fluid in the fluid refill space 510 may flow through the fluid refill port 202 and to the fluid reservoir space 220. For another example, the switch body 320 may also close the fluid-filling port 202 when the fluid level in the fluid-storage space 220 rises above a preset fluid level value, so that the fluid in the fluid-filling space 510 cannot flow through the fluid-filling port 202.

In the case that the liquid amount of the liquid replenishing container 500 is sufficient, by arranging the liquid level switch 300 in the liquid storage space 220, the liquid level in the liquid storage space 220 can be ensured to be always approximately maintained at the preset liquid level value, so that the liquid level in the reaction space 210 is further ensured to be always maintained above the safe liquid level value. The preset level value may be set according to a safe level value within the reaction space 210. In this embodiment, the liquid storage space 220 and the reaction space 210 form a communicating vessel, and the preset liquid level value is equal to the safe liquid level value.

In some alternative embodiments, the interior of the reaction space 210 defines a plurality of reaction subspaces 211. The electrolytic oxygen removing assemblies 100 are plural and are arranged in one-to-one correspondence with the reaction subspaces 211, and each electrolytic oxygen removing assembly 100 is arranged in one reaction subspace 211. Each reaction subspace 211 can be directly or indirectly communicated with the liquid storage space 220, so that the liquid in the liquid storage space 220 can be utilized for supplementing liquid.

Because the electrolytic oxygen removing assemblies 100 are multiple, and each of the reaction subspaces 211 in which the electrolytic oxygen removing assemblies 100 are positioned can receive the electrolyte from the liquid storage space 220, the electrolytic oxygen removing assemblies 100 can perform electrochemical reactions simultaneously, and therefore, the electrolytic oxygen removing device 10 of the invention has high oxygen removing efficiency.

Each electrolytic oxygen removal assembly 100 may be independently electrochemically reactive. By controlling the operating conditions of the plurality of electrolytic oxygen removal assemblies 100, one or more of the electrolytic oxygen removal assemblies 100 can be selectively activated to perform oxygen removal according to actual oxygen removal requirements, which is advantageous in improving the flexibility of the electrolytic oxygen removal device 10.

In some further embodiments, the electrolytic oxygen removal device 10 may further include at least one second separator 600 disposed within the reaction space 210 to separate a plurality of reaction subspaces 211 inside the reaction space 210. Each second partition 600 is provided with a second communication port 610 for communicating with the adjacent reaction subspace 211.

The number of the second separators 600 is set according to the number of the reaction subspaces 211, for example, one second separator 600 when the reaction subspaces 211 are two, and three second separators 600 when the reaction subspaces 211 are four.

Each of the second partitions 600 is vertically disposed such that the plurality of reaction subspaces 211 are horizontally arranged side by side. The second communication port 610 is located at a bottom section of the corresponding second separator 600. For example, the second separator 600 may be a partition plate, which may be formed inside the case 200 by a molding process.

Having multiple reaction subspaces 211 side by side horizontally ensures that each electrolytic oxygen removal assembly 100 is exposed to the air within the working environment, thereby allowing electrochemical reactions to proceed using the oxygen in the air as a reactant.

Fig. 4 is a schematic structural view of an electrolytic oxygen removing device 10 according to still another embodiment of the present invention.

In some alternative embodiments, the electrolytic oxygen depletion device 10 may further include a packaging container 800 and a waste storage container 900. The packaging container 800 is packaged outside the housing 200, and is used for containing the electrolyte overflowed from the housing 200, so as to prevent the electrolyte from leaking into the external space of the packaging container 800. The waste container 900 communicates with the packaging container 800 for storing electrolyte overflowed to the packaging container 800. For example, the waste container 900 may be connected to the packaging container 800 using a transfer tube, and the waste container 900 is disposed below the packaging container 800.

By adding the packaging container 800 and the waste storage container 900, leakage of the electrolyte in the case 200 to the external space other than the packaging container 800 and the waste storage container 900 due to occurrence of accidents can be avoided, thereby being advantageous to improve the safety performance of the entire electrolytic oxygen removing apparatus 10.

With respect to the structure of the electrolytic oxygen removal assembly 100, an exemplary embodiment will be described.

The electrolytic oxygen removal assembly 100 may generally include an anode plate and a cathode plate. In the energized condition, the cathode plate is used to consume oxygen through the electrochemical reaction. For example, oxygen in the air may undergo a reduction reaction at the cathode plate, namely: o (O) ₂ +2H ₂ O+4e ^- →4OH ^- . The OH-generated by the cathode plate can generate oxidation reaction at the anode plate and generate oxygen, namely: 4OH ^- →O ₂ +2H ₂ O+4e ^- . Oxygen may be vented through vent 201 in housing 200.

The case 200 is provided with an opening on a sidewall of the reaction space 210, and the cathode plate may be disposed at the opening and define the reaction space 210 for containing the electrolyte together with the case 200. The anode plate may be disposed in the reaction space 210 to be spaced apart from the cathode plate.

Fig. 5 is a schematic structural view of a liquid level switch 300 of the electrolytic oxygen removing device 10 according to an embodiment of the present invention, fig. 6 is a schematic exploded view of the liquid level switch 300 of the electrolytic oxygen removing device 10 shown in fig. 5, and fig. 7 is a schematic perspective view of the liquid level switch 300 of the electrolytic oxygen removing device 10 shown in fig. 5. As for the structure of the liquid level switch 300, an exemplary embodiment will be described below.

The liquid level switch 300 further includes a float 320 fixedly connected with the switch body 310 or integrally formed with the switch body 310, for driving the switch body 310 to move by floating or sinking around a shaft in the liquid storage space. That is, the switch body 310 is "driven" by the float 320, and the power required for the float 320 to move is determined by the buoyancy it receives in the liquid storage space.

For example, a portion of the float 320 is immersed in the liquid, thereby subjecting the float 320 to buoyancy by the liquid. When the liquid level in the liquid storage space changes, the buoyancy force borne by the floater 320 also changes, so that the resultant force of the buoyancy force borne by the floater 320 and the gravity force changes. For example, when the liquid level in the liquid storage space decreases, the buoyancy force exerted by the float 320 decreases, and if the resultant force of the buoyancy force exerted by the float 320 and the gravity force is downward, the float 320 is caused to move downward. Conversely, this will cause the float 320 to move upwardly. The float 320 may rise or fall in a vertical direction, or may rise or fall in a curve.

In some alternative embodiments, the float 320 is rotatably disposed about an axis. That is, the float 320 of the present embodiment does not move up and down along a straight line, but moves up or down in a pivoting manner, and thus, the float 320 is only required to be pivotally connected to a fixed shaft, and a guide member having high dimensional accuracy is not required to be installed, so that the present embodiment has the advantages of compact structure, simple assembly process, and good device reliability.

Since the float 320 is rotatably disposed around the shaft, the movement track is clear and definite, so that the float 320 and the switch body 310 of the embodiment are easy to move along the clear and definite movement track, thereby improving the reliability of the liquid level switch 300 and reducing or avoiding the problem of sealing inaccuracy caused by the free movement of the float 320.

The fluid level switch 300 may further include a rotation shaft 340 and a connection 330.

Wherein the rotation shaft 340 is fixed to the liquid storage space. For example, the rotation shaft 340 may be fixedly connected to the inner wall of the container of the liquid storage space.

In some alternative embodiments, the rotation shaft 340 may also be detachably fixed in the liquid storage space, which may adjust the height of the rotation shaft 340 according to actual needs, thereby adjusting the liquid level in the liquid storage space where the liquid replenishment starts.

The connection member 330 is fixedly connected with the float 320 or is an integral piece with the float 320, and has a shaft hole 341 formed thereon for the rotation shaft 340 to be inserted therein and rotatably fitted to achieve the rotatable connection. That is, the connection 330 assembles the rotation shaft 340 and the float 320 into an organic whole such that the float 320 can rotate about the rotation shaft 340.

By providing the shaft hole 341 in the connector 330 and rotatably fitting the rotation shaft 340 to the shaft hole 341, the float 320 can be rotatably fitted to the rotation shaft 340 around the shaft, and the structure is fine and the process is simple.

The switch body 310 has a rod shape. The connection member 330 is further formed with a mounting hole 342 for a portion of the switch body 310 to be inserted therein to achieve a fixed assembly. That is, a portion of the switch body 310 is fixedly coupled with the float 320 indirectly by being fixedly assembled with the coupling member 330. For example, a portion of the switch body 310 may be assembled with the mounting hole 342 of the connector 330 by an interference fit.

The rotation shaft 340 and the switch body 310 are assembled to the connection member 330 fixedly connected to the float 320 or integrally formed with the float 320, respectively, thereby forming the liquid level switch 300 with strong structural integrity. The switch body 310 and the float 320 are located on the same side of the rotation shaft 340. The fact that the switch body 310 is on the same side as the floater 320 means that the switch body 310 is located between the rotating shaft 340 and the floater 320 is the key that the switch body 310 makes the same-direction movement with the floater 320 according to the liquid level of the inner space of the liquid storage space, and a larger force arm ratio can be obtained.

In this embodiment, the central axis of the rotation shaft 340 extends in the horizontal direction and is perpendicular to the central longitudinal vertical symmetry plane of the float 320. For example, for a cylindrical float 320, when the two bottom surfaces 321 of the float 320 are disposed opposite in the horizontal direction, the central longitudinal vertical symmetry plane of the float 320 is the longitudinal central section of the float 320 extending in the vertical direction. In the case where the switch body 310 closes the fluid-replenishing port 202, the central axis of the mounting hole 342 extends in the vertical direction and is parallel to the central longitudinal vertical center line of the float 320, wherein the central longitudinal vertical center line of the float 320 is the longitudinal center line of the longitudinal center section of the float 320 extending in the vertical direction. The azimuthal terms such as "horizontal" and "longitudinal" are all relative to the actual use state of the liquid level switch 300, and the longitudinal direction is substantially vertical.

In some alternative embodiments, float 320 is hollow cylindrical. The cylindrical body of the float 320 of this embodiment has a hollow structure, so that buoyancy (overall density is smaller than that of the liquid) can be further improved. The central axis of the float 320 is parallel to the central axis of the shaft hole 341. Wherein the central axes of the floats 320 are respectively collinear with the centers of the two bottom surfaces 321. Since the central axis of the shaft hole 341 extends in the horizontal direction, the central axis of the float 320 also extends in the horizontal direction, and the two bottom surfaces 321 of the float 320 are disposed opposite to each other in the horizontal direction.

In some alternative embodiments, the connector 330 is cantilevered and extends obliquely outward and upward from an upper section of the cylinder side 322 of the float 320. Wherein "outwardly" refers to radially outwardly along the cylinder sides 322.

The switch body 310 is a rod-shaped plug cover, and has a fitting portion 311 and a blocking portion 312. Wherein the fitting portion 311 is a rod and is fixedly fitted to the mounting hole 342. The plugging portion 312 is a plug cover, and is connected to the top of the fitting portion 311, for opening or closing the fluid infusion port 202. The plug cover can be cylindrical, and the upper surface of the plug cover is planar. Compared with the matching structure of the traditional conical head plug and the water nozzle, the matching mechanism of the plug cover and the lower annular flange of the embodiment has the advantage of high position fault tolerance, the plug cover does not need to be precisely aligned with the liquid outlet of the lower annular flange, and the conical water nozzle can be covered on the upper surface of the plug cover. The plug cover and the rod of the embodiment are integrated.

A central section of the inner wall of the mounting hole 342 is formed with a central annular flange 342a extending radially inward. The main body rod 311c of the fitting portion 311 has the same rod diameter as the hole diameter of the middle annular flange 342a so as to be inserted into the hole defined by the middle annular flange 342a. The fitting portion 311 also has an upper annular boss 311a and a lower annular boss 311b extending radially outwardly from the main body stem 311c thereof, above and below the middle annular flange 342a, respectively, to limit the degree of freedom of movement of the switch body 310 with respect to the mounting hole 342.

By designing the hole structure of the mounting hole 342 and the rod structure and plug structure of the switch body 310, the structural stability of the overall structure obtained by the fixed assembly between the switch body 310 and the mounting hole 342 can be improved.

In some alternative embodiments, the switch body 310 is made of an acid and alkali resistant elastic material, such as ethylene propylene diene monomer rubber or fluororubber, and the like, and presses the fluid infusion port 202 in sealing engagement therewith by virtue of elastic deformation thereof, thereby achieving sealing. The rotation shaft 340 is made of an acid and alkali resistant material such as a chrome plated metal material, a ceramic material, or a plastic material. The float 320 may be made of an acid and alkali resistant material such as polytetrafluoroethylene or polybutylene adipamide.
