Referring to fig. 1, an electrochemical oxygen regulating device 10 of the present utility model may generally include a housing 110, a reservoir 120, and a make-up reservoir 130, which are separately provided.
Fig. 2 is a schematic structural view of an electrochemical oxygen regulating apparatus according to an embodiment of the present utility model, referring to fig. 2, a reaction space 111 is defined inside a housing 110, an oxygen regulating assembly 112 is disposed in the reaction space 111, and the oxygen regulating assembly 112 is used for performing an electrochemical reaction under the action of an electrolysis voltage to regulate oxygen in a preset space. In some embodiments, adjusting the oxygen in the preset space may refer to consuming the oxygen through an electrochemical reaction, or may refer to generating the oxygen through an electrochemical reaction. The preset space may be a storage space of a refrigerator in which the electrochemical oxygen regulating device 10 is located.
The liquid storage space 121 for containing liquid is formed inside the liquid storage container 120, and the liquid storage space 121 is communicated with the reaction space 111 through the first pipeline 151 to supplement liquid to the reaction space 111.
The fluid replacement container 130 has a fluid replacement space 131 for containing fluid, and the fluid replacement space 131 communicates with the fluid storage container 120 through a second pipe 152 to replace fluid in the fluid storage space 121.
The electrochemical oxygen regulating device 10 of the present utility model includes a housing 110 defining a reaction space, a liquid reservoir 120, and a liquid replenishing container 130. The liquid storage space 121 and the liquid supplementing space 131 for containing liquid are respectively defined in the liquid storage container 120 and the liquid supplementing container 130, and the liquid storage space 121 is communicated with the reaction space 111 through the first pipeline 151 so as to supplement liquid to the reaction space 111 in time, and the oxygen regulating component 112 in the reaction space 111 is prevented from influencing the electrochemical reaction due to lack of necessary reaction liquid. And, the fluid-replenishing container 130 is communicated with the fluid-storing container 120 through the second pipeline 152, so as to be convenient for replenishing the fluid-storing space 121 when the fluid quantity in the fluid-storing space 121 is reduced or insufficient, so that the fluid-storing space 121 can continuously provide the liquid required by the reaction to the reaction space, and the fluid level in the reaction space 111 is always kept at a higher level. Therefore, the utility model forms double fluid replacement guarantee by arranging the fluid storage container 120 and the fluid replacement container 130, has very perfect fluid replacement function, and basically eliminates the problem of electrolyte deficiency.
In addition, the shell 110, the liquid storage container 120 and the liquid supplementing container 130 are arranged separately, on one hand, the number, the combination form, the gas path structure and the like of the oxygen regulating components 112 in the shell 110 are not influenced by the liquid storage container 120, and in the modularized expansion process, the expansion and the structure installation are facilitated; the combination form of the oxygen adjusting component 112 is flexible and changeable, and particularly, one ventilation channel can be shared, so that the thickness of the shell 110 after assembly is reduced; on the other hand, the volume of a single component is reduced, the shell 110, the fluid infusion container 120 and the fluid reservoir 130 with relatively small volumes are conveniently distributed and arranged at different positions of the refrigerator, the position arrangement flexibility of each component of the electrochemical oxygen regulating device 10 is improved, and scattered small spaces on the refrigerator can be fully and effectively utilized.
In addition, the shell 110, the liquid storage container 120 and the liquid supplementing container 130 are separately arranged, when any one of the oxygen regulating assembly 112, the liquid storage container 120 or the liquid supplementing container 130 is damaged, normal use of other structures is not affected, only the damaged structure is needed to be replaced, other structures are not needed to be replaced, and the maintenance cost is reduced.
In some embodiments, the liquid storage container 120 is provided with a first liquid supplementing port 122 and a first liquid outlet 123. The second pipeline 152 is communicated with the first fluid supplementing port 122 so as to supplement fluid to the fluid storage space 121 through the first fluid supplementing port 122; the first pipe 151 communicates with the first liquid outlet 123 to allow the liquid in the liquid storage space 121 to flow to the reaction space 111 through the first liquid outlet 123 and the first pipe 151 in order, thereby replenishing the reaction space 111 with liquid.
Further, the first fluid-filling port 122 is located at a height higher than that of the first fluid-outlet 123, so as to fill the fluid-storage space 121 with fluid, and also to fill the reaction space 111 with fluid from the first fluid-outlet 123.
Specifically, the height of the first fluid-replenishing port 122 is appropriately high, and a large amount of fluid can be replenished into the fluid storage space 121, so that the fluid in the fluid storage space 121 is maintained at a high level. The height of the first liquid outlet 123 is suitably low, and even if the liquid level in the liquid storage space 121 drops to a certain extent, the liquid can be supplied to the reaction space 111 through the first liquid outlet 123.
In some embodiments, the electrochemical oxygen regulating device 10 further includes a liquid level control portion 140, where the liquid level control portion 140 is disposed inside the liquid storage container 120 and corresponds to the first liquid supplementing port 122. The liquid level control part 140 is configured to selectively open the first replenishing port 122 according to the liquid level height in the liquid storage space 121 to allow the replenishing container 130 to replenish the liquid storage space 121 or to block the first replenishing port 122 to prevent the liquid in the replenishing container 130 from flowing into the liquid storage space 121.
For example, the liquid level control part 140 may open the first liquid supplementing port 122 when the liquid level in the liquid storage space 121 decreases below a preset liquid level height value, so that the liquid in the liquid supplementing space 131 may flow to the liquid storage space 121 through the first liquid supplementing port 122, thereby supplementing the liquid storage space 121. For another example, the liquid level control portion 140 may also seal the first liquid supplementing port 122 when the liquid level in the liquid storage space 121 rises to another preset liquid level height value, the liquid in the liquid supplementing space 131 cannot flow to the liquid storage space 121 through the first liquid supplementing port 122, at this time, the liquid supplementing to the liquid storage space 121 is stopped, and the liquid in the liquid storage space 121 cannot flow back to the liquid supplementing space 131.
In some embodiments, the first conduit 151 is configured such that the liquid level in the liquid storage space 121 and the reaction space 111 remain uniform. Specifically, no valve body or switch may be disposed in the first pipe 151, and when the liquid level in the liquid storage space 121 is higher than the liquid level in the reaction space 111, the liquid in the liquid storage space 121 may automatically flow to the reaction space 111 through the first pipe 151 under the potential energy difference until the liquid levels are leveled.
FIG. 3 is a schematic structural schematic diagram of an oxygen regulating assembly according to one embodiment of the utility model. In some embodiments, the oxygen regulating assembly 112 includes a cathode portion 1121 and an anode portion 1122 disposed at intervals, the cathode portion 1121 being configured to consume oxygen in a predetermined space through an electrochemical reaction, the anode portion 1122 being configured to provide a reactant to the cathode portion 1121 through the electrochemical reaction and generate oxygen.
The cathode portion 1121 is configured to consume oxygen through an electrochemical reaction when energized. For example, oxygen in the air in the preset space may undergo a reduction reaction at the cathode portion 1121, that is: o (O) 2 +2H 2 O+4e - →4OH - . OH generated from the cathode portion 1121 - An oxidation reaction may occur at the anode portion 1122 and oxygen gas may be generated, namely: 4OH - →O 2 +2H 2 O+4e - . The anode portion 1122 uses OH - At the same time as the electrochemical reaction takes place, the cathode part is also supplied with reactants, e.g. electrons e - . The oxygen generated in the anode portion 1122 is discharged through an exhaust pipe connected to an exhaust port. Specifically, the anode portion 1122 may be a positive electrode, such as a nickel mesh or a titanium mesh; the cathode 1121 may be a negative electrode, such as a catalytic film containing silver and manganese dioxide.
It should be understood that the above examples of electrochemical reactions with respect to the anode portion 1122 and the cathode portion 1121 are merely illustrative, and those skilled in the art should readily modify the types of electrochemical reactions or develop the structure of the electrochemical oxygen regulating device 10 suitable for other types of electrochemical reactions while remaining within the scope of the present utility model.
Further, the position of the liquid level control portion 140 is set so that the lowest liquid level in the liquid storage space 121 is not lower than 90% of the height of the cathode portion 1121. That is, the position of the liquid level control portion 140 may be selected such that the lowest liquid level of the liquid storage space 121 is higher than or equal to 90% of the height of the cathode portion 1121. Since the liquid level in the reaction space 111 is equal to the liquid level in the liquid storage space 121, the lowest liquid level in the reaction space 121 is also higher than or equal to 90% of the height of the cathode portion 1121 to ensure that at least a large part of the area of the cathode portion 1121 is in contact with the electrolyte. Wherein 90% of the height of the cathode portion 1121 means a position at a distance of 90% of the entire height of the cathode portion 1121 from the bottom of the cathode portion 1121.
If the minimum liquid level of the liquid storage space 121 is too low, the minimum liquid level in the reaction space 111 will be too low, which will make the larger area of the cathode 1121 not contact with the electrolyte, a larger air cavity may be formed, and when the external pressure is larger, the generated oxygen will be discharged to the preset space through the cathode 1121 again through the air cavity, so as to reduce the oxygen regulating speed.
Preferably, the lowest liquid level of the liquid storage space 121 is not lower than the highest point of the cathode 1121. That is, in the preferred embodiment, the lowest liquid level of the liquid storage space 121 is higher than the highest point position of the cathode portion 1121 or is flush with the highest point position of the cathode portion 1121, so that the lowest liquid level of the reaction space 111 is higher than the highest point position of the cathode portion 1121 or is flush with the highest point position of the cathode portion 1121, thereby ensuring that the entire cathode portion 1121 is in contact with the electrolyte.
In a specific embodiment, when the liquid level in the liquid storage space 121 is lower than the preset liquid level value, the liquid level control part 140 opens the first liquid supplementing port 122 to start supplementing liquid to the liquid storage space 121. Therefore, the lowest liquid level in the liquid storage space 121 is the liquid level at which the liquid level control section 140 is about to open or just opens the first liquid replenishing port 122. Therefore, the lowest liquid level in the liquid storage space 121 can be adjusted by the position selection of the liquid level control section 140.
In some embodiments, the reaction space 111 may include a plurality of reaction subspaces, each of which is directly or indirectly communicated with the liquid storage space 121, so that the plurality of reaction subspaces are replenished with one liquid storage space 121. Each reaction subspace is internally provided with an oxygen adjusting component 112, and the plurality of oxygen adjusting components 112 can perform electrochemical reactions independently, so that one or more oxygen adjusting components 112 can be selectively started according to actual requirements, the use flexibility of the electrochemical oxygen adjusting component 10 is improved, and the energy consumption of the electrochemical oxygen adjusting component is reduced as much as possible.
Fig. 4 is a schematic structural view of a liquid level control part according to an embodiment of the present utility model. In some embodiments, the liquid level control 140 may be a liquid level switch that includes a switch body 141 and a float 142. The float 142 is fixedly connected with the switch body 141 or is an integral part of the switch body 141, and the float 142 is configured to rotate up and down around the rotating shaft under the action of the buoyancy of the liquid in the liquid storage space 121 and the gravity of the liquid, so as to drive the switch body 141 to move.
Specifically, when the liquid level in the liquid storage space 121 decreases, the buoyancy force borne by the float 142 decreases, and if the resultant force of the buoyancy force borne by the float 142 and the gravity thereof is downward, the float 142 sinks and rotates to drive the switch body 141 to have a downward displacement component, so as to gradually open the first liquid supplementing port 122. Conversely, when the liquid level in the liquid level space 121 rises, the buoyancy force borne by the float 142 increases, and if the resultant force of the buoyancy force borne by the float 142 and the gravity thereof is upward, the float 142 floats and rotates to drive the switch body 141 to have an upward displacement component, so as to gradually block the first fluid-filling port 122.
Since the structure and operation principle of the liquid level switch type liquid level control part 140 are easily known to those skilled in the art, the description thereof is omitted herein.
In other embodiments, the liquid level control portion 140 may be other components that can selectively open or close the first liquid supplementing port 122 according to the liquid level in the liquid storage space 121, which will not be described herein.
In some embodiments, the fluid replacement container 130 is in gas circuit communication with the housing 110, such that the gas generated during the electrochemical reaction of the oxygen adjustment assembly 112 flows through the liquid in the fluid replacement space 131, so that the specific substance carried in the gas is dissolved in the liquid.
The fluid infusion container 130 of the utility model is also in gas circuit communication with the housing 110, and the gas generated when the oxygen regulating assembly 112 performs electrochemical reaction flows through the liquid in the fluid infusion space 131, so that the specific substances (such as electrolyte) carried in the gas can be dissolved in the liquid in the fluid infusion space 131, thereby reducing the specific substances discharged along with the gas, and reducing or even avoiding the environmental pollution caused in the gas discharge process.
In addition, the liquid in the liquid replenishing container 130 is utilized to filter the gas, on one hand, the liquid in the liquid replenishing container 130 can be finally replenished to the reaction space 111 through the liquid storage container 120, and the electrolyte dissolved in the liquid is replenished to the reaction space 111 again, so that the consumption of specific substances in the electrochemical oxygen regulating device 10 is slowed down or even avoided; on the other hand, the liquid replenishing container 130 is integrated with a filtering function, and a filtering device is not required to be additionally arranged, so that the necessary components of the electrochemical oxygen regulating device 10 are reduced, and the structure is simplified.
In some embodiments, the housing 110 is provided with an exhaust port 113 in communication with the reaction space 111 to exhaust gas generated when the oxygen regulating assembly 112 performs an electrochemical reaction through the exhaust port 113. The fluid infusion container 130 is in air path communication with the housing 110 via an exhaust pipe 153, a first end of the exhaust pipe 153 is in communication with the exhaust port 113, and a second end of the exhaust pipe 153 extends into the fluid infusion space 131. Thus, the gas generated by the oxygen regulating assembly 112 is introduced into the liquid in the liquid supplementing space 131 through the exhaust pipe 153, and is discharged after being filtered by the liquid in the liquid supplementing space 131, so that the cleaning degree of the discharged gas is improved.
Further, the fluid infusion container 130 is provided with a second liquid outlet 132 for communicating the fluid infusion space 131 with the second pipeline 152, and the second liquid outlet 132 is higher than the second end of the exhaust pipe 153. Thus, the second end of the exhaust pipe 153 is always immersed in the liquid supplementing space 131, and all the gas discharged from the exhaust pipe 153 flows through the liquid in the liquid supplementing space 131 for filtering, so that environmental pollution caused by direct discharge of unfiltered gas is avoided.
In some embodiments, the fluid replacement container 130 is provided with an air outlet 133, so that the air filtered by the fluid in the fluid replacement space 131 is discharged from the air outlet 133. The maximum liquid level of the liquid replenishing container 130 is lower than the height of the gas outlet 133 to ensure that the filtered gas is smoothly discharged from the gas outlet 133.
If the maximum liquid level of the liquid replenishing container 130 is too high, for example, equal to or higher than the height of the gas outlet 133, the gas outlet 131 may be blocked by the liquid in the liquid replenishing space 131, so that the filtered gas cannot be discharged.
Specifically, the air outlet 133 may be formed at the top of the fluid infusion container 130, so that the air flowing out of the fluid infusion container 130 may be reduced to carry the fluid, and the air may be easily exhausted.
In some embodiments, a second fluid-refill port 134 is provided at the top of the fluid-refill container 130 to refill the fluid-refill space 131 with external fluid through the second fluid-refill port 134. The fluid infusion space 131 is further provided with an air-blocking plate 135 for dividing the fluid infusion space 131 into a first subspace and a second subspace which are horizontally adjacent, the air-blocking plate 135 extends downwards from the top of the fluid infusion container 130 to form an overflow gap 136 with the bottom wall of the fluid infusion container 130 at intervals, and the first subspace and the second subspace are communicated through the overflow gap 136. The second fluid-filling port 134 communicates with the first subspace, the air outlet 133 communicates with the second subspace, and the second end of the air outlet pipe 153 extends into the second subspace.
Since the second fluid-supplementing port 134 communicates with the first subspace, the fluid supplemented from the second fluid-supplementing port 134 can directly flow into the first subspace. The first subspace communicates with the second subspace via the overflow gap 136, whereby the liquid in the first subspace can flow to the second subspace, so that the liquid level in the second subspace and the first subspace is leveled. Since the second liquid supplementing port 134, the air outlet 133 and the air outlet 153 are respectively located at two sides of the air resistance plate 135, and the air resistance plate 135 has a blocking effect on air, the air in the liquid discharged from the air outlet 153 into the second subspace is not basically diffused into the first subspace located at the other side of the air resistance plate 135, but is completely discharged from the air outlet 133 communicated with the second subspace, so that the filtered air is prevented from overflowing from the second liquid supplementing port 134 to affect the oxygen regulating effect in the preset space.
The present utility model also provides a refrigerator 1, and fig. 5 is a schematic structural view of a refrigerator according to an embodiment of the present utility model. The refrigerator 1 particularly includes the electrochemical oxygen regulating device 10 described in any of the embodiments above.
The refrigerator 1 provided by the utility model is provided with the electrochemical oxygen regulating device 10, and can quickly create a low-oxygen and/or high-oxygen space in the refrigerator 1 so as to store food materials with different oxygen content requirements.
