As will be appreciated by those skilled in the art, the arrangement of the liquid replenishing chamber 1102 and the gas washing chamber 1103 as shown in fig. 1 to 4, the arrangement of the anode terminal 121 and the cathode terminal 122, and the orientation of the liquid replenishing port 1104 as shown in fig. 1 to 4, make the overall structure of the air conditioning apparatus 100 more compact, effectively reducing the spatial dimension of the air conditioning apparatus 100.
As shown in fig. 5 to 7, in some embodiments of the present utility model, a first liquid passing port 1108 is provided on a side wall between the liquid supplementing chamber 1102 and the reaction chamber 1101 to communicate the two, so that the liquid in the liquid supplementing chamber 1102 flows to the reaction chamber 1101 through the first liquid passing port 1108. A second liquid passing port 1109 communicating the two is provided on the side wall between the liquid supplementing chamber 1102 and the gas washing chamber 1103, so that the liquid in the liquid supplementing chamber 1102 flows to the gas washing chamber 1103 through the first liquid passing port 1108.
The first liquid passing port 1108 is located at the top of the liquid supplementing cavity 1102 and is lower than the liquid supplementing port 1104, so as to ensure that the liquid in the liquid supplementing cavity 1102 can smoothly enter the reaction cavity 1101.
The second liquid passing port 1109 is located at the bottom of the liquid supplementing cavity 1102, so that the liquid supplementing cavity 1102 and the gas washing cavity 1103 form a communicating vessel structure, and therefore liquid in the liquid supplementing cavity 1102 enters the gas washing cavity 1103.
As will be appreciated by those skilled in the art, the first fluid passage 1108 is located at the top of the fluid replacement chamber 1102 below the fluid replacement port 1104, and the second fluid passage 1109 is located at the bottom of the fluid replacement chamber 1102 to ensure that the fluid in the purge chamber 1103 is of sufficient height when the fluid replacement chamber 1102 is completed for the reaction chamber 1101.
The height of each flow port/hole in the container 110 is described below with reference to fig. 5-8. It should be noted that the heights marked in fig. 5 to 8 are relative to the bottom surface of the container 110.
As shown in fig. 5 to 8, the height of the lowest position of the fluid-filling port 1104 is denoted as H1, the height of the lowest position of the first fluid-passing port 1108 is denoted as H2, the height of the highest position of the second fluid-passing port 1109 is denoted as H3, the height of the lowest position of the first bleed hole 1106 is denoted as H4, the height of the highest position of the second bleed hole 1107 is denoted as H5, the height of the lowest position of the exhaust port 1105 is denoted as H6, and the height of the anode plate 123 is denoted as H.
As can be seen from fig. 5 to 8, the height h1 of the fluid-filling port 1104 is greater than the height h2 of the first fluid-passing port 1108, and the height h2 of the first fluid-passing port 1108 is greater than the height h3 of the second fluid-passing port 1109, i.e., h1 > h2 > h3. It will be appreciated by those skilled in the art that by having h1 > h2 > h3, it is possible to ensure that the liquid in the make-up chamber 1102 flows to the reaction chamber 1101 and the purge chamber 1103.
As can be seen from fig. 5 to 8, the height h4 of the first bleed holes 1106 is greater than the height h2 of the first bleed holes 1108. Those skilled in the art can also ensure that the liquid in the liquid replenishment chamber 1102 does not flow out through the first bleed holes 1106 by having h4 > h2 as desired.
As can be seen from fig. 5 to 8, the height h5 of the second bleed holes 1107 is greater than the height h3 of the second bleed holes 1109, i.e. h5 > h3. The person skilled in the art can also ensure that oxygen entering the liquid supplementing chamber 1102 from the reaction chamber 1101 via the first liquid passing port 1108 can only enter the gas washing chamber 1103 via the path of the first gas introducing hole 1106, the gas introducing pipe 130 and the second gas introducing hole 1107, but not the gas washing chamber 1103 via the second liquid passing port 1109, by making h5 > h3 such that the liquid pressure at the second gas introducing hole 1107 is larger than the liquid pressure at the second liquid passing port 1109, as required. The specific principle is as follows:
as shown in fig. 5 and 6, a communicating vessel structure is formed between the fluid supplementing chamber 1102 and the gas washing chamber 1103 through the second fluid passing port 1109, and for convenience of description, the communicating vessel is referred to herein as a first communicating vessel; another communicating vessel structure is formed between the fluid supplementing chamber 1102 and the gas washing chamber 1103 by the first gas-entraining hole 1106, the gas-entraining pipe 130 and the second gas-entraining hole 1107, and for convenience of description, the communicating vessel is referred to herein as a second communicating vessel.
It will be appreciated by those skilled in the art that after the air conditioning apparatus 100 is completed, the liquid levels in the liquid replenishment chamber 1102, the purge chamber 1103 and the bleed air duct 130 are equal, while the transverse cross section of the liquid replenishment chamber 1102 is much greater than the transverse cross section of the bleed air duct 130, resulting in the liquid level in the liquid replenishment chamber 1102 being much greater than the liquid level in the bleed air duct 130, and therefore the liquid in the liquid replenishment chamber 1102 is much greater than the liquid in the bleed air duct 130. Since gas enters the purge chamber 1103 from the make-up chamber 1102, it can only pass through the second tap 1109 and bleed duct 130.
If the gas introducing pipe 130 is not provided, the liquid in the liquid replenishing chamber 1102 enters the gas washing chamber 1103 through the second liquid passing opening 1109, and the liquid in the liquid replenishing chamber 1102 is not lowered to the second liquid passing opening 1109 due to the fact that the liquid in the liquid replenishing chamber 1102 is more, the liquid in the gas washing chamber 1103 is more and flows out from the gas outlet 1105.
In the case that the bleed pipe 130 is provided and the height h5 of the second bleed hole 1107 is greater than the height h3 of the second through-liquid port 1109, when the liquid level in the liquid supplementing chamber 1102 is lowered to the height h3 of the second through-liquid port 1109, the gas in the liquid supplementing chamber 1102 can enter the gas washing chamber 1103 through the bleed pipe 130.
Since some of the liquid in the liquid replenishing chamber 1102 may enter the gas washing chamber 1103 before the gas in the liquid replenishing chamber 1102 enters the gas washing chamber 1103, resulting in an increase in the liquid level in the gas washing chamber 1103, in other embodiments of the present utility model, the person skilled in the art may also make the height h5 of the second air introducing hole 1107 as high as possible if necessary, on the premise that the height h5 of the second air introducing hole 1107 is lower than the lowest liquid level in the gas washing chamber 1103.
Further, although not shown, in some embodiments of the utility model, the air regulating device 100 may further include a liquid level sensor for detecting the liquid level in the reaction chamber 1101.
Illustratively, a fluid level sensor is mounted within reaction chamber 1101 and is configured to detect a maximum and minimum height of a fluid level within reaction chamber 1101.
Still further, although not shown, in some embodiments of the utility model, the modified atmosphere device 100 may further include a one-way valve disposed at the fluid refill port 1104 or in fluid communication with the fluid refill port 1104, the one-way valve configured to permit fluid flow only from the exterior of the container 110 to the fluid refill chamber 1102.
As will be appreciated by those skilled in the art, the one-way valve enables the fluid replacement port 1104 to automatically close after fluid replacement of the air conditioning apparatus 100 is completed, thereby preventing air from being discharged from the fluid replacement port 1104 and affecting the air cleaning function of the air conditioning apparatus 100.
The fluid replacement principle of the air conditioner 100 according to some embodiments of the present utility model will be described with reference to fig. 2 to 8.
First, the air conditioner 100 is connected to an external water source for supplying water to the air conditioner 100 through the fluid supply port 1104. The external water source includes a water storage box and a water pump for pumping water within the water storage box to the air conditioning device 100.
When the liquid level sensor detects that the liquid level in the reaction chamber 1101 decreases by a minimum height, the water pump delivers the water in the water storage box to the liquid supplementing chamber 1102. Water in the fluid replacement chamber 1102 first enters the purge chamber 1103 through the second fluid passage 1109. When the water in the liquid supplementing cavity 1102 rises to the first liquid passing port 1108, the water enters the reaction cavity 1101 through the first liquid passing port 1108. When the liquid level sensor detects that the liquid level in the reaction chamber 1101 reaches the maximum height, the water pump stops working, and water supplementing is stopped.
It should be noted that, in order to prevent the electrolyte in the reaction chamber 1101 from flowing back to the liquid replenishing chamber 1102 and even to the gas washing chamber 1103, the gas washing effect of the water in the gas washing chamber 1103 is affected, and the liquid level sensor detects that the maximum height in the reaction chamber 1101 is lower than the lowest height H2 of the first liquid passing port 1108, and thus the height H of the anode plate 123 is also lower than H2.
Based on the foregoing description, it can be appreciated by those skilled in the art that the air conditioner 100 in some embodiments of the present utility model not only avoids the operation of separately replenishing the air-washing chamber 1103, but also reduces the space size of the air conditioner 100 because the vessel 110 defines the reaction chamber 1101, the liquid replenishing chamber 1102 and the air-washing chamber 1103 simultaneously, so that the overall structure of the air conditioner 100 is more compact.
In other embodiments of the present utility model, as shown in fig. 9, the present utility model also provides a fresh keeping apparatus 200, where the fresh keeping apparatus 200 includes a case 210 and the air conditioning device 100 described in any of the foregoing embodiments.
With continued reference to fig. 9, in other embodiments of the utility model, the housing 210 defines a hypoxic space 211 and the air conditioning apparatus 100 is configured to consume oxygen within the hypoxic space 211.
Further, the housing 210 may further define a high oxygen space 212, and the air-conditioning device 100 may be further configured to supply oxygen to the high oxygen space 212, so that the air-conditioning device 100 increases the oxygen concentration in the high oxygen space 212 while reducing the oxygen concentration in the low oxygen space 211.
In the present utility model, the fresh-keeping apparatus 200 may be a fresh-keeping apparatus 200 having a refrigerating and/or freezing function, such as a refrigerator, freezer, refrigerator, etc.
It will be appreciated by those skilled in the art that the fresh-keeping apparatus 200 of the present utility model can prevent the electrolyte from entering the fresh-keeping apparatus 200 along with oxygen, contaminating food materials, and corroding the refrigerator when using the modified atmosphere device 100 described in any of the embodiments above.
Thus far, the technical solution of the present utility model has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present utility model is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present utility model, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present utility model will fall within the protection scope of the present utility model.
