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 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 CO3、K ₂ CO3, etc., concentration of electrolyteCan 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.

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. And continuously generating oxygen, taking away part of electrolyte particles, and discharging from an 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.

In view of the above problems, the present inventors have proposed an air conditioner and a refrigerator that overcome or at least partially solve the above problems, and aim to solve the problem that the air conditioner cannot work normally due to too little electrolyte in the prior art, thereby achieving the effect of improving user experience.

In some embodiments of the present utility model, the fluid level detection assembly 120 includes at least one contact-type second fluid level switch, at least a detection portion of which extends into the working space 113. For example, the second liquid level switch is a float type liquid level switch, the detection unit is a float, and the float contacts the surface of the electrolyte in the working space 113, moves along with the up-and-down floating of the electrolyte, and when the electrolyte rises or falls to a certain position, the second liquid level switch can be turned on or off, and further a control signal is output.

In some embodiments of the present utility model, as shown in fig. 1 to 8, the electrolysis assembly 112 is immersed in the electrolyte, with a buffer space 130 between the top of the electrolysis assembly 112 and the top of the working space 113, and the liquid level detection assembly 120 is located within the buffer space 130.

In some embodiments of the utility model, the liquid level detection assembly comprises two liquid level switch sets, each liquid level switch set comprising at least one non-contact first liquid level switch and/or contact second liquid level switch, the liquid level switches of each liquid level switch set being at the same height. One liquid level switch set is positioned above the other liquid level switch set. Because each liquid level switch group has a plurality of liquid level switches for liquid level detection is more accurate, prevents that only one liquid level switch from measuring error or breaking down.

In some embodiments of the utility model, the number of two fluid level switch sets is equal, with one first fluid level switch or second fluid level switch of one fluid level switch set being directly above one first fluid level switch or second fluid level switch of the other fluid level switch set.

For example, the first liquid level threshold is a low liquid level threshold and the first response signal is a fluid replacement signal. When the liquid level is equal to or lower than the first liquid level threshold, the air-conditioning device 100 needs to supplement the electrolyte, the liquid level detection assembly 120 outputs a liquid supplementing signal, and the air-conditioning control module acquires the liquid supplementing signal to complete liquid supplementing.

The air conditioning control module is further configured to: in response to the duration of the first response signal not being obtained being below the first time threshold and the operating load of the electrolysis assembly 112 being below the load threshold, a fault signal of the liquid level detection assembly 120 is generated. For example, the work load is an operating current of the air conditioning apparatus 100, and the load threshold may be a current threshold. As described in detail above, the electrolyte decreases with the time of use, so the liquid level detecting component 120 may send the liquid replenishing signal at intervals, where the time is the first time threshold. When the air conditioner 100 works, the time period when the fluid replacement signal is not obtained is greater than or equal to the first time threshold, and the working current is greater than or equal to the current threshold, which indicates that electrolyte does not need to be replaced, but the fluid level detection assembly 120 does not send the fluid replacement signal within the first time threshold, the fluid level detection assembly 120 breaks down, at this time, the air conditioner module generates a fault signal of the fluid level detection assembly 120, and the air conditioner 100 can be normally used before maintenance.

In some embodiments of the present utility model, as shown in fig. 1-8, the working space 113 communicates with a fluid-filled port 114, the fluid-filled port 114 being configured to allow at least electrolyte outside the working space 113 to be injected into the working space 113.

For example, electrolyte in the reservoir space 200 may be delivered into the working space 113 by a make-up pump. In some alternative embodiments, the air conditioning apparatus 100 may include a liquid storage space 200, the liquid storage space 200 being disposed above the working space 113, and the electrolyte in the liquid storage space 200 may enter the working space 113 under the action of gravity to supplement the electrolyte consumed in the working space 113.

When the liquid level is equal to or lower than the first liquid level threshold, that is, the low liquid level threshold, the air-conditioning device 100 needs to supplement electrolyte, the liquid level detection assembly 120 outputs a fluid-supplementing signal, and the air-conditioning control module acquires the fluid-supplementing signal to complete fluid supplementation.

The air conditioning control module is further configured to: in response to the number of times the make-up signal is generated within the set time not being below the response threshold and the operational load of the electrolytic assembly 112 not being above the load threshold, a fault signal is generated that corresponds to at least the leakage of electrolyte. That is, a plurality of fluid-filling signals are generated within a set time and the working space 113 is filled a plurality of times, but the working current is still less than or equal to the current threshold, and the electrolyte leaks, and a fault signal of electrolyte leakage is generated. Through such configuration of the air-conditioning control module, the electrolyte leakage condition can be found in time, the maintenance can be performed in time, and the situation that the air-conditioning device cannot work normally is avoided.

The air conditioning control module is further configured to: in response to the number of times the make-up signal is generated within the set time not being below the response threshold and the operating load of the electrolysis assembly 112 not being below the load threshold, a fault signal of the liquid level detection assembly 120 is generated. That is, after the multiple fluid replacement signals are generated within the set time and the working space 113 is replenished with fluid multiple times, the working current is greater than or equal to the current threshold, which indicates that the fluid level detection assembly 120 is malfunctioning, and generates a malfunction signal of the fluid level detection assembly 120. Through such configuration of the air-conditioning control module, the fault condition of the liquid level detection assembly 120 can be found in time, and maintenance can be performed in time, so that the condition that the air-conditioning device cannot work normally is avoided.

In some embodiments of the utility model, the working space 113 communicates with a fluid replenishment port 114, the fluid replenishment port 114 being configured to at least enable a fluid replenishment pump to inject electrolyte into the working space 113, wherein the fluid replenishment pump is configured to shut down in response to the fluid discharge pressure not being below a fluid discharge threshold. When the liquid discharge pressure is greater than or equal to the liquid discharge threshold value, the liquid discharge of the liquid supplementing pump is not smooth, so that the liquid discharge pressure is increased, and a pipeline between the liquid supplementing pump and the liquid supplementing port 114 is blocked, so that the liquid supplementing pump needs to be stopped for maintenance.

The air conditioning apparatus 100 further includes an air conditioning control module, which connects the liquid level detection assembly 120 and the electrolysis assembly 112, and is configured to: and generating a start signal of the fluid supplementing pump in response to the liquid level height not being higher than the first liquid level threshold. When the liquid level is less than or equal to the first liquid level threshold, i.e. the low liquid level threshold, it indicates that the liquid level is too low, and the liquid needs to be replenished, at this time, the air-conditioning module generates a startup signal of the replenishing pump to replenish the electrolyte into the working space 113.

The air conditioning control module is further configured to: in response to the operating load of the electrolytic assembly 112 not being above the load threshold for a set time after the power-on signal is generated, a fault signal is generated that the line between the fluid replacement pump and the fluid replacement port 114 is blocked. That is, the start-up signal of the fluid infusion pump has been generated for a set time, the fluid infusion pump has also been operated for a set time, but the operating current is still less than or equal to the current threshold, which indicates that the pipeline between the fluid infusion pump and the fluid infusion port 114 is blocked, the electrolyte does not enter the working space 113 or the amount of the electrolyte entering the working space 113 is insufficient, and at this time, the air-conditioning control module generates a fault signal of the pipeline blocking between the fluid infusion pump and the fluid infusion port 114, so as to perform maintenance in time.

In some embodiments of the present utility model, as shown in fig. 1 to 8, at least one fluid-compensating port 114 and at least one air-exhausting port 115 are formed at the top of the working space 113. The air conditioning module can absorb oxygen in the storage space, oxygen is generated in the working space 113 through electrochemical reaction, the oxygen gathers in the working space 113 to increase the pressure in the working space 113, the electrochemical reaction can be affected, and the oxygen needs to be discharged in time, so that the exhaust port 115 is arranged. The number of fluid-supplementing ports 114 and air-exhausting ports 115 may be set as desired.

The air conditioner 100 further includes an anti-overflow mechanism configured to: in response to the liquid level not being below the second liquid level threshold, the fluid refill port 114 is closed. The second liquid level threshold is a high liquid level threshold, although the high liquid level threshold is here relative to the low liquid level threshold in the above described embodiments. When the liquid level is higher than or equal to the second liquid level threshold, the electrolyte is at risk of overflowing, so that the liquid supplementing port 114 needs to be closed in time, 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. 1-8, the anti-overflow mechanism comprises a float 151, the float 151 being disposed within the working space 113 and floating on the level of the electrolyte, the top of the float 151 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 151 may move with the liquid level floating up and down, and when the liquid level reaches a second level threshold, i.e., a high level threshold, a sealing portion at the top of the float 151 may close the fluid refill port 114. The sealing portion may be made of an elastic material. Alternatively, in some other embodiments, a closure device connected to the top of the float 151 may close the fluid refill port 114. For example, the closure device may be a relatively large area waterproof breathable membrane, may close the fluid-filled port, prevent the passage of liquid, and allow the passage of gas.

In some embodiments of the utility model, the anti-overflow mechanism further comprises a guide member disposed within the working space 113 and in up-and-down reciprocal guided connection with the float 151, the guide member having an upper stop structure and/or a lower stop structure formed thereon, wherein the upper stop structure is configured to stop at an upper floating highest position of the float 151 and the lower stop structure is configured to stop at a lower sinking lowest position of the float 151. The float 151 is driven by the liquid level and reciprocates up and down under the limitation of the guide member, and at this time, the sealing portion or the sealing means may be made smaller as long as it can cover the liquid replenishment port 114.

In some embodiments of the present utility model, as shown in fig. 1 to 8, the overflow prevention mechanism further includes a guide rod 152 extending vertically, an upper end of the guide rod 152 being positioned at the top of the working space 113, and a lower end of the guide rod 152 being provided with a horizontally overhanging bar 153. The float 151 is formed with a guide hole which is slidably coupled to the guide rod 152 in a vertically reciprocating manner, and the float 151 is stopped between the top of the working space 113 and the stop rod 153. Due to the guide rod, the stop lever and the guide hole, the float 151 can reciprocate up and down under the driving of the liquid level, so that the liquid supplementing port 114 can be sealed, and the size of the sealing part or the sealing device can be not too large.

The oxygen generated by the air conditioning device 100 can be discharged into other spaces in the refrigerating and freezing device, and the generated oxygen amount is small relative to the volume of the other spaces, so that the other spaces are not affected. Of course, the generated oxygen may be discharged to the outside of the refrigerating and freezing apparatus through a pipe.
