The air-conditioning fresh-keeping technology is a mode of controlling the proportion of air in a closed space to achieve the aim of storage and fresh-keeping. The basic principle is as follows: in a certain closed space, the regulating gas different from the normal atmospheric components is obtained through various regulating modes, the physiological and biochemical processes and the microbial activities which cause food spoilage are inhibited, and for fruits and vegetables, the aerobic respiration of the fruits and vegetables is mainly inhibited, the accelerated spoilage of the fruits and vegetables is prevented, and the preservation time of the fruits and vegetables is further prolonged. The air-conditioning fresh-keeping technology is realized by an air-conditioning device.

The key of the fresh-keeping technology of the air-conditioning device is to condition the air.

For ease of understanding, the prior art of one configuration of an air conditioning device based on electrochemical reactions will first be described by way of example as follows.

In some embodiments, the air conditioning apparatus generally includes a cathode plate and an anode plate immersed in an electrolyte. The cathode plate is communicated with the closed space and is used for absorbing oxygen in the closed space through electrochemical reaction under the action of electrolytic voltage so as to provide reactants for the anode plate. The electrochemical reaction is mainly in yinThe polar plate and the anode plate, and the oxygen in the air undergoes a reduction reaction at the cathode plate, namely: o (O) ₂ +2H ₂ O+4e ^- →4OH ^- . OH generated by the cathode plate ^- Can be used as a reactant of the anode plate.

The anode plate is communicated with the outside of the air regulating device and is used for releasing oxygen to the outside of the air regulating device through electrochemical reaction by utilizing reactants under the action of electrolytic voltage. OH generated by cathode plate ^- An oxidation reaction can occur at the anode plate and produce oxygen, namely: 4OH ^- →O ₂ +2H ₂ O+4e ^- 。

The air-conditioning device can form an oxygen-deficient gas atmosphere in the closed space by consuming oxygen in the closed space, so that the food in the closed space can be preserved conveniently.

In some embodiments, the air conditioning device may further comprise a housing. The housing may be generally in the shape of a flat cuboid. The housing may be provided with a lateral opening which may be located outside the housing and communicate with the external environment, for example, with a sealed space for fresh keeping. The cathode plate is arranged at the lateral opening to jointly define a liquid storage cavity for containing electrolyte with the shell. The anode plate is arranged in the liquid storage cavity and is arranged at intervals with the cathode plate.

One of the walls of the housing, for example the outer wall of the housing, may be opened to form a lateral opening opposite the external environment. The negative plate in the embodiment can be directly used as the outer wall surface of the shell for sealing the liquid storage cavity. The liquid storage cavity of the air-conditioning device can contain alkaline electrolyte, such as NaOH and KOH with the concentration of 1mol/L, and can be Na ₂ CO ₃ 、K ₂ CO ₃ And the like, the concentration of the electrolyte can be adjusted according to actual needs.

In some embodiments, the air conditioner further comprises a separator disposed in the liquid storage cavity and located between the cathode plate and the anode plate for separating the cathode plate and the anode plate, so as to prevent the air conditioner from being shorted after being electrified. Specifically, a plurality of protruding parts are formed on one side, facing the anode plate, of the separator, the protruding parts are abutted against the anode plate, and the cathode plate is abutted against one side, deviating from the protruding parts, of the separator, so that a preset gap is formed between the cathode plate and the anode plate, and the cathode plate and the anode plate are separated.

In some embodiments, the air conditioner further comprises a fixing assembly disposed on an outer side of the cathode plate and configured to fix the cathode plate to the lateral opening of the housing. In particular, the fixation assembly may further include a metal bezel and a support. The metal frame is attached to the outer side of the cathode plate. The metal frame is in direct contact with the cathode plate, can play a role in compacting the cathode plate, and is also provided with a cathode power supply terminal of the cathode plate so as to be connected with an external power supply. The anode plate may have an anode power supply terminal formed thereon.

The support is formed with a socket. When the surrounding vertical part of the metal frame is inserted into the inserting groove of the supporting piece, the metal frame can be fixed and positioned by the supporting piece, and then the metal frame is pressed against the cathode plate.

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

Of course, the air conditioner device does not need to comprise a power supply device, and the power supply device is a peripheral power supply device. For example, when the air conditioner is arranged in the refrigerating and freezing device and is communicated with the fresh-keeping space in the refrigerating and freezing device, the air conditioner can be electrically connected to the power supply module of the refrigerating and freezing device so as to provide electric energy for the air conditioner, so that the size of the refrigerating and freezing device can be reduced, and the air conditioner is more convenient to carry and install.

The structure of an air conditioner has been described. From the above description, it is known that the cathode plate and the anode plate must be immersed in the electrolyte to perform the electrochemical reaction normally. However, in the working process of the actual air regulating device, oxygen generated by the air regulating device at the anode plate forms a plurality of tiny bubbles in the electrolyte, and the bubbles float to the surface of the electrolyte and then break to form tiny electrolyte particles which are suspended above the electrolyte. The continuously generated oxygen can lead the liquid level of the electrolyte to fluctuate, and the oxygen can take away part of electrolyte particles and is discharged from the air outlet of the air conditioning device. Electrolyte can be reduced along with the use process, and the negative plate and the positive plate of the air conditioner can expose the electrolyte, so that the working efficiency of the air conditioner is affected. When the electrolyte is reduced to a certain degree, even electrochemical reaction cannot be performed at all, the deoxidization fresh-keeping effect is reduced, the fresh-keeping time of food materials is shortened, and the user experience is poor.

In view of the above problems, the present inventors have proposed an air conditioning apparatus and a refrigeration and freezing apparatus for overcoming the above problems or at least partially solving the above problems, and have aimed at solving the problem that the anode plate is exposed easily due to the fluctuation of the electrolyte in the prior art, so as to achieve the purpose of improving the user experience.

When the liquid level is higher than or equal to the high liquid level threshold, the electrolyte is at risk of overflowing, so that the liquid supplementing port 114 needs to be closed in time by 0, and the overflow prevention mechanism plays a role in closing the liquid supplementing port 114.

In some embodiments of the utility model, as shown in fig. 1, 3-8, the anti-overflow mechanism comprises a float 131, the float 131 being disposed within the reservoir space 112 and floating on the level of the electrolyte, the top of the float 131 forming at least one closure disposed relatively below the fluid-refill port 114 and/or connecting at least one closure means disposed relatively below the fluid-refill port 114. The float 131 can move along with the up-and-down floating of the liquid level, and when the liquid level reaches a liquid level threshold, namely a high liquid level threshold, a sealing part at the top of the float 131 can seal the liquid supplementing port 114.

In some embodiments of the present utility model, the opening area of the fluid-refill port 114 is smaller than the upper end area of the closure portion and/or the closure device for closing the fluid-refill port 114 with a portion of the upper end surface of the closure portion and/or the closure device. To ensure that the closure and closure device are capable of sealing the fluid-filled port 114, the area of the upper ends of the closure and closure device should be greater than the open area of the fluid-filled port 114. In particular, when the gas device does not include a guide member, a guide rod, or the like, the area of the upper ends of the closing portion and the closing means should be set larger. This is because the float is driven by the liquid level to float in both the up-down direction and the horizontal direction of the liquid level, and in order to ensure that the closing portion and the closing device seal the liquid replenishing port 114 in the process of floating upward, the area of the upper ends of the closing portion and the closing device should be set larger than the opening area of the liquid replenishing port 114. When the gas device comprises a guide part or a guide rod, the float is driven by the liquid level and is only floated in the up-down direction under the limit of the guide part or the guide rod, and the area of the upper ends of the sealing part and the sealing device is only required to be slightly larger than the opening area of the liquid supplementing port 114, so that the float can be ensured to be lifted to the highest position, and the liquid supplementing port 114 can be sealed.

In some embodiments of the utility model, there are at least two fluid-filled ports 114 spaced apart from each other, each fluid-filled port 114 being adapted to the same float for closing each fluid-filled port 114 after one float has floated. The number of fluid-filling ports 114 may be set as desired, but it is necessary to ensure that one float can close each fluid-filling port 114 after floating up to the highest position. In addition, each of the fluid-filling ports 114 also needs to be adapted to the same connection pipe for injecting the electrolyte into each of the fluid-filling ports 114 through one connection pipe. Of course, the fluid-supplementing port 114 may be one.

In some embodiments of the utility model, the fluid level detection assembly includes at least one non-contact first fluid level switch, one of which is disposed outside the base. For example, the first liquid level switch is a capacitive liquid level switch. The first liquid level switch can be stuck on the outer wall of the matrix without being in direct contact with electrolyte, so that the first liquid level switch cannot be corroded by strong alkali solution, and the service life of the first liquid level switch is prolonged. The first liquid level switch can also be located in the base body, in order to prevent corrosion of the first liquid level switch by the alkali solution, the cavity wall of the base body is sunken to form a groove, the groove cavity of the groove and the liquid storage space are arranged at intervals, and the first liquid level switch is installed in the groove. Of course, the first level switch may also be located directly in the base body.
