Specifically, as the electrolyte reacts electrochemically and generates a large amount of gas, the electrolyte fluctuates; because the cathode plate and the first shell are integrally formed or fixedly connected in other modes, the position of the cathode plate relative to the first shell is fixed, so that the electrolyte is easy to drive the anode plate to displace during electrochemical reaction; the air regulating device applies pressure to the anode plate through the pressing column, so that the anode plate is clamped between the connecting step and the pressing column, and the anode plate is also fixed in the first shell as the connecting step and the pressing column are respectively fixed on the first shell and the second shell of the electrolysis device; so that the electrolyte can not cause displacement of the cathode plate and the anode plate when performing electrochemical reaction and generating a large amount of gas; the cathode plate and the anode plate are not influenced by electrolyte fluctuation, so that the distance between the anode plate and the cathode plate is fixed, and the working state of the whole air conditioning device is stabilized.

As a preferred embodiment of the present utility model, the first housing 11 is framed and the second housing 12 is plate-shaped; the first casing 11 and the second casing 12 may be fastened by means of a butt joint or may be fastened by means of welding to form a sealed environment inside the electrolytic chamber.

Of course, in other embodiments of the present utility model, the first housing 11 and the second housing 12 may have other shapes that can be sealed as a whole, and the connection steps 111 may be provided in plurality.

As shown in fig. 2, and referring to fig. 1, in some embodiments of the utility model, the anode plate 13 includes:

at least two connection ears 131, each connection ear 131 being in the same plane as the anode plate 13 and being formed at an edge of the anode plate 13 and protruding outward; the connection lugs 131 are arranged in one-to-one correspondence with the connection steps 111, so that the connection lugs 131 are lapped on the connection steps 111 in one-to-one correspondence.

Preferably, the connecting ears 131 are provided with 8; when the anode plates 13 are placed on the connecting steps 111, the connecting lugs 131 are in one-to-one correspondence with the connecting steps 111, and then the anode plates 13 are placed on the connecting steps 111, so that each connecting lug 131 can be lapped on the corresponding connecting step 111, and the placement of the anode plates 13 is completed.

In some embodiments of the present utility model, a reaction space is also formed in the electrolytic chamber, the reaction space being a space between the anode plate 13 and the cathode plate 14;

the edges of two adjacent connecting lugs 131 and the edge of the anode plate 13 jointly form a ventilation opening;

As a preferred embodiment of the present utility model, the edges of each two adjacent connecting ears 131 and the edges of the anode plate 13 together form a ventilation opening, so to speak, a gap is formed between the edges of the anode plate 13 and the side wall of the first housing 11.

During the electrochemical reaction, when air around the air conditioner 10 flows over the surface of the cathode plate 14, oxygen in the air combines with electrolyte in the electrolyte and generates water under the electrolysis action of the cathode plate 14; the electrolyte then reacts electrochemically with the anode plate 13 again and oxygen is again generated. Oxygen formed on the surface of the anode plate 13 facing the reaction space floats up in the electrolyte after entering the reaction space and is discharged from the ventilation opening, so that oxygen generated in the electrochemical reaction can be timely discharged from the air conditioning device 10.

As shown in fig. 1, in some embodiments of the present utility model, the press studs 121 are provided in at least two, and the press studs 121 are disposed in one-to-one correspondence with the connection steps 111, so that each connection ear 131 of the anode plate 13 is clamped between one set of connection steps 111 and the press studs 121.

As a preferred embodiment of the present utility model, the above-mentioned press studs 121 are provided with 8, 8 press studs 121 correspond to 8 connection steps 111, respectively, and in assembling the air conditioner 10, the electrolytic assembly is first installed in the electrolytic chamber of the first housing 11, which includes placing all the connection lugs 131 of the anode plate 13 at the corresponding connection steps 111 in the electrolytic chamber so that the edge of the anode plate 13 can overlap the connection steps 111, and then, when the second housing 12 is installed, each press stud 121 formed on the second housing 12 is moved above the connection lug 131 of the anode plate 13, and the opposite connection lug 131 of the anode plate 13 is located between the press stud 121 and the connection step 111, and after the second housing 12 is installed, the assembly of the electrolytic container is substantially completed, and each connection lug 131 of the anode plate 13 is clamped between a set of press studs 121 and the connection steps 111.

By forming the pressing post 121 provided opposite to the above-mentioned connection step 111 in the second case 12 of the electrolytic vessel, each connection ear 131 of the anode plate 13 can be clamped between a set of the connection step 111 and the pressing post 121; since the connection step 111 and the press post 121 are fixedly formed on the electrolytic container and each connection lug 131 of the anode plate 13 is clamped between the connection step 111 and the press post 121, the anode plate 13 is also indirectly fixed in the electrolytic container, so that the distance between the anode plate 13 and the cathode plate 14 is fixed and is not influenced by fluctuation of electrolyte, and the working state of the whole air conditioner 10 is stabilized.

In some embodiments of the present utility model, the press stud 121 forms a first hole extending in an axial direction and penetrating therethrough, the connection lug 131 forms a second hole communicating with the first hole, and the connection step 111 forms a third hole communicating with the second hole; and, the connection bolt sequentially passes through the first hole, the second hole and the third hole to connect the press post 121, the connection lug 131 and the connection step 111 together.

As a preferred embodiment of the present utility model, the first, second and third holes are screw holes, and the connection bolt is sequentially rotated into the first, second and third holes to tightly connect the pressing post 121, the connection lug 131 and the connection step 111 together, and in addition, it is also possible to be engaged with the nut after the connection bolt is sequentially rotated into the first, second and third holes to prevent the bolt from being separated from the first, second and third holes.

In some alternative embodiments of the present utility model, the second housing 12 may be directly coupled to the coupling lug 131 and the coupling step 111 by passing the coupling bolt through the second hole and the third hole in sequence without forming the press stud 121 thereon.

The arrangement makes the connection between the anode plate 13 and the first shell 11 and the second shell 12 tighter, so that the integral structure of the air conditioner 10 is stronger and durable, and the service life of the air conditioner 10 is prolonged.

As shown in fig. 3, in some embodiments of the present utility model, ventilation holes 132 extending in the axial direction and penetrating through the anode plate 13 are further formed on the anode plate 13, and at least two ventilation holes 132 are provided, and the ventilation holes 132 are distributed in an array on the anode plate 13.

In some preferred embodiments of the present utility model, the ventilation hole 132 may be a circular hole, a square hole, or a shaped hole formed on the anode plate 13 with a large opening area (or a large opening).

In some preferred embodiments of the present utility model, the ventilation holes 132 are distributed in an array on the anode plate 13. This makes the ventilation holes 132 exist everywhere on the anode plate 13, and oxygen formed on the surface of the anode plate 13 can be discharged from the ventilation holes 132 at adjacent positions, which is more advantageous for oxygen discharge. As an alternative embodiment of the present utility model, the ventilation holes 132 may be radially or annularly distributed on the anode plate 13, which can also have the effect of increasing the oxygen discharge rate; furthermore, the air hole 132 may be one, and the position of the air hole 132 may be selected according to the test, so long as the position of the air hole 132 is properly selected, especially, the air hole is formed at a position where oxygen aggregation is likely to occur, and the effect of accelerating the oxygen discharging speed is also achieved.

In some preferred embodiments of the present utility model, the opening area of one vent 132 or the sum of the opening areas of at least two vents 132 is smaller than the reaction area of the anode plate 13. Specifically, when one ventilation hole 132 is formed in the anode plate 13, the opening area of the ventilation hole 132 is smaller than the reaction area of the anode plate 13, which is the surface area of the portion of the anode plate 13 immersed in the electrolyte and participating in the electrochemical reaction; when there are more than two ventilation holes 132, the sum of the opening areas of all ventilation holes 132 is also smaller than the reaction area. Because the total area of the ventilation holes 132 is smaller than the reaction area, the efficiency of the electrochemical reaction of the anode plate 13 is higher, especially the generation speed of oxygen generated by the electrochemical reaction is higher than the discharge speed of oxygen discharged from the ventilation holes 132, so that an oxygen positive pressure space is formed around the anode plate 13, the oxygen is conveniently discharged, an oxygen-enriched atmosphere is more easily formed on one side of the anode plate 13 far away from the cathode plate 14, air is isolated, and the reaction of other substances in the air and the anode plate 13 is avoided. Furthermore, when the electrolyte is still present above the anode plate 13, the oxygen-enriched atmosphere keeps the oxygen discharge channel open, and oxygen is more easily discharged.

In some embodiments of the present utility model, the reaction area is equal to 1 to 2 times the opening area of one vent 132 or the sum of the opening areas of at least two vents 132. Particularly, through a great number of experimental tests, under the condition of considering the reaction area and the exhaust efficiency of the anode plate 13, the ratio of the occupied area of the air holes 132 on the anode plate 13 to the reaction area (the occupied area of the air holes 132 is subtracted) is 1:1.2 the anode plate 13 produces more oxygen than is discharged, and a certain exhaust gas pressure is generated, which is sufficient to discharge the gas from the gap and into the exhaust pipe, and then the gas is discharged to the outside. The maximum oxygen production amount of the anode plate 13 is ensured under the same area. Thus, in some embodiments of the air regulating device 10 of the present utility model, the oxygen production efficiency and the oxygen discharge rate are guaranteed to reach a certain balance and by reasonable ratio values of the oxygen permeation area and the anode electrochemical reaction area

As shown in fig. 1, in some embodiments of the utility model, the cathode plate 14 is integrally formed with the first housing 11.

As some preferred embodiments of the present utility model, the cathode plate 14 is integrally formed on the first housing 11. This arrangement facilitates the installation of the air conditioning device 10 and also facilitates the installation and maintenance of the cathode plate 14 on the first housing 11. Preferably, the cathode plate 14 may be molded onto the first housing 11 by injection molding, with the one-shot connection of the cathode plate 14 and the first housing 11 being accomplished in an injection mold.

Further, as some alternative embodiments of the present utility model, the anode plate 13 may also be integrally formed on the first housing 11. This arrangement facilitates the installation of the air conditioner 10 and also facilitates the installation and maintenance of the anode plate 13 on the first housing 11. Preferably, the anode plate 13 may be formed on the first housing 11 by injection molding, and the one-time-formed connection of the anode plate 13 and the first housing 11 is completed in an injection mold.

As shown in fig. 1, in some embodiments of the present utility model, the second housing 12 and the first housing 11 are disposed in sequence from top to bottom;

the anode plate 13, the connection step 111, and the cathode plate 14 are disposed in the electrolytic chamber in this order from top to bottom.

As a preferred embodiment of the present utility model, the first housing 11 is disposed at the lowest position, an electrolysis chamber is formed in the first housing 11, a cathode plate 14, a connection lug 131 and an anode plate 13 are sequentially installed in the electrolysis chamber from bottom to top, an electrolyte is further contained in the electrolysis chamber for performing electrochemical reaction, and finally the second housing 12 is disposed above the first housing 11 and fastened and fixed with the first housing 11, so that a sealed environment is formed inside the electrolysis container.

In some alternative embodiments of the present utility model, the second housing 12 and the first housing 11 are both disposed vertically, and the electrolytic assembly is disposed vertically inside the first housing 11, wherein the second housing 12 and the first housing 11 are disposed in order from left to right, and the anode plate 13, the connection step 111, and the cathode plate 14 are disposed in order from left to right in the electrolytic chamber; alternatively, the second housing 12 and the first housing 11 are disposed in this order from right to left, and the anode plate 13, the connection step 111, and the cathode plate 14 are disposed in this order from right to left in the electrolytic chamber.

As shown in fig. 4, an embodiment of the present utility model further provides a refrigerating and freezing apparatus 1, which includes:

a storage compartment 20, wherein a storage space 30 for storing is formed in the storage compartment 20; as with the air-conditioning apparatus 10 of any of the embodiments described above, the air-conditioning apparatus 10 is mounted on the storage compartment 20 and communicates with the storage space 30.

Specifically, the storage compartment 20 is preferably a sleeve, and a storage drawer that can be pushed and pulled back and forth in the sleeve is disposed in the sleeve, and an inner space of the storage drawer is a storage space 30, which can be used for storing food. The sleeve is provided with a vent which is communicated with the air regulating device 10. In the process that the storage drawer is pushed and pulled back and forth in the sleeve, oxygen in the air outside the box 40 enters the storage space 30 of the storage drawer, so that storage and fresh keeping of food materials are not facilitated. The air conditioning device 10 is thus assembled on the storage compartment 20. After the air conditioning device 10 is started, the anode plate 13 and the cathode plate 14 in the air conditioning device 10 are electrified, and under the action of electrolysis voltage, the electrolyte is subjected to electrochemical reaction and absorbs oxygen from the storage space 30 so as to provide reactants for the anode plate 13; preferably, the electrolyte consists essentially of water and an electrolyte, the electrolyte being soluble in the water to form the electrolyte. The electrochemical reaction is mainly performed at the cathode plate 14 and the anode plate 13, and the oxygen in the storage space 30 undergoes a reduction reaction at the cathode plate 14, so that the oxygen is absorbed and OH-is generated. OH "generated by the cathode plate 14 may continue to act as a reactant for the anode plate 13 and generate water and oxygen.

The arrangement can realize the absorption of oxygen in the storage space 30 through the air conditioning device 10, and prolongs the storage time and the fresh-keeping time of the stored food in the storage space 30.

In some embodiments of the present utility model, the case 40 is opened forward, and the air conditioner 10 is located at a position rearward or at a rear side of the top of the storage compartment 20.

Specifically, the above-described ventilation opening is provided on the rear side wall of the storage compartment 20, that is, the rear side wall of the sleeve, and the air-conditioning device 10 is preferably provided at the rear upper side of the storage compartment 20, that is, the rear upper side of the sleeve.

As some alternative embodiments of the present utility model, the air conditioner 10 may be vertically disposed, that is, the first housing 11 and the second housing 12 of the air conditioner 10 are vertically disposed; at this time, the air-conditioning device 10 is embedded in the rear side of the storage compartment 20, especially the air-conditioning device 10 can be centrally disposed in the rear center of the storage compartment 20, and compared with the horizontally-disposed air-conditioning device 10, the vertically-disposed air-conditioning device 10 does not occupy the space above the storage compartment 20, so that the storage volume of the storage compartment 20 is increased, and more food can be stored.

In some embodiments, the air conditioning device 10 further comprises a power supply device, such as a mains or a battery. The two electrode terminals of the power supply device are electrically connected to the corresponding cathode power supply terminal and anode power supply terminal of the air conditioner 10, respectively, and provide power for the electrochemical reaction. The air conditioner 10 of the present embodiment is provided with a power supply device, so that the cathode component and the anode component of the air conditioner 10 respectively perform electrochemical reactions under the action of electrolysis voltage.

Of course, the air conditioner 10 may not include a power supply device, and the power supply device is a peripheral power supply device. For example, when the air conditioning device 10 is disposed in the refrigerating and freezing device 1 and is communicated with the fresh-keeping space in the refrigerating and freezing device 1, the air conditioning device 10 can be electrically connected to the power supply module of the refrigerating and freezing device 1 to provide electric energy for the air conditioning device, so that the size of the refrigerating and freezing device 1 can be reduced, and the carrying and the installation are more convenient.

In some preferred embodiments of the present utility model, the support posts are connected in a bracing manner between the middle portion of the anode plate 13 and the middle portion of the cathode plate 14, and the support posts and the ventilation holes 132 are spaced apart. Considering that the anode plate 13 may be a plate or a membrane structure, and the cathode plate 14 may be a plate or a membrane structure, the relative positions of the edges of the anode plate 13 and the edges of the cathode plate 14 may be relatively fixed to the first housing 11, especially when the anode plate 13 and the cathode plate 14 are both in a membrane structure. However, the center of the cathode plate 14 and the anode plate 13 are arranged up and down, so that sagging easily occurs relative to the edge position, and when sagging degrees are different, electrochemical reactions can be caused to be different in reaction efficiency at all positions of the electrolytic module, therefore, the relative distance between the cathode plate 14 and the anode plate 13 can be kept through the supporting columns, so that the reaction efficiency at all positions of the electrolytic module is basically consistent, on one hand, the electrochemical reactions are more reliable and controllable, and on the other hand, the reaction consumption at all positions of the anode plate 13 and the cathode plate 14 is relatively consistent, the local damage speed of the cathode plate 14 and the anode plate 13 is avoided, the service life of the electrolytic module is prolonged, the overhaul period of the air conditioning device 10 is prolonged, and the overhaul cost is reduced, thereby being more beneficial to popularization, application, overhaul and maintenance of the refrigeration and freezing device 1.

The anode plate 13 may be composed of a metal plate or a nickel plate or a metal film or a nickel film. The cathode plate 14 includes a catalytic layer, a first waterproof layer, a current collecting layer, and a second waterproof layer, which are sequentially connected. The catalytic layer has a catalyst, activated carbon, PTFE, and the like. The first waterproof layer and the second waterproof layer have PTFE, activated carbon, and the like. The collector layer includes an electrode, nickel mesh, and the like.
