[0002] With rapid economic development and the continuous improvement of people's living standards, people have increasingly higher requirements for the air comfort of their living and working environments. Air conditioners, as a relatively ideal appliance for regulating indoor temperature, are widely used. During use, in order to maintain the indoor temperature and for energy-saving considerations, doors and windows are usually closed. As the closure time increases, the indoor oxygen content gradually decreases, which may cause discomfort to the human body, such as narrowed attention span, increased mental fatigue, and decreased visual sensitivity.

[0003] In existing technologies, the common method to increase indoor oxygen levels is to introduce fresh outdoor air. However, the introduced fresh air causes changes in the indoor temperature, which reduces user comfort and affects the user experience.

[0008] The electrolysis box is provided with a gas outlet. The anode electrode and cathode electrode are inserted into the electrolysis box for electrolyzing the water in the electrolysis box. The oxygen and hydrogen produced by the electrolysis of water are discharged from the electrolysis box through the gas outlet.

[0009] In the preferred embodiment of the above-mentioned humidification and oxygenation device, the water electrolysis oxygen generation mechanism further includes an ion exchange membrane, which is disposed in the electrolysis box and divides the electrolysis box into an anode chamber and a cathode chamber that are connected at the bottom. The anode electrode is inserted into the anode chamber and the cathode electrode is inserted into the cathode chamber.

[0010] The air outlet includes a first air outlet and a second air outlet. The first air outlet is connected to the anode chamber, and the second air outlet is connected to the cathode chamber.

[0011] In the preferred embodiment of the above-mentioned humidification and oxygenation device, a hydrogen discharge pipe is provided in the second air outlet, and the end of the hydrogen discharge pipe away from the electrolysis box extends to the outside.

[0012] In the preferred embodiment of the above-mentioned humidification and oxygenation device, the electrolytic water oxygen generation mechanism further includes a first fan, which is mounted on the electrolysis box and connected to the anode chamber. The first fan is capable of discharging the gas in the anode chamber through the first air outlet; and / or

[0013] The water electrolysis oxygen generation mechanism also includes a second fan, which is mounted on the electrolysis box and connected to the cathode chamber. The second fan can discharge the gas in the cathode chamber through the second air outlet.

[0014] In the preferred embodiment of the above-mentioned humidification and oxygenation device, the water supply mechanism includes a water supply tank and a liquid seal pipe. The water supply tank is located above the electrolysis box. The inlet end of the liquid seal pipe is connected to the water supply tank. The outlet end of the liquid seal pipe extends into the electrolysis box, and there is a liquid level maintenance gap between the outlet end of the liquid seal pipe and the bottom of the electrolysis box.

[0015] In the preferred embodiment of the above-mentioned humidification and oxygenation device, the water supply tank is provided with an inlet and an outlet, and the water supply mechanism further includes a sealing component for sealing the outlet.

[0016] When the inlet end of the liquid seal pipe is not inserted into the outlet, the sealing assembly seals the outlet, and the liquid seal pipe is disconnected from the water supply tank.

[0017] When the inlet end of the liquid seal pipe is inserted into the outlet, the sealing assembly no longer seals the outlet, and the liquid seal pipe is connected to the water supply tank.

[0018] In the preferred embodiment of the above-mentioned humidification and oxygenation device, the sealing assembly includes a sealing plug, which is inserted into the water outlet; or

The oxygen produced by water electrolysis is discharged into the room through the first outlet, while the hydrogen is discharged directly to the outside through the hydrogen exhaust pipe. This can increase the indoor oxygen content more quickly and reduce the indoor hydrogen content at the same time. The first and second fans can further accelerate the discharge of oxygen into the room and the discharge of hydrogen to the outside, and have little impact on the indoor temperature.

[0026] In addition, the water in the anode chamber is atomized by the humidification mechanism, and the resulting atomized droplets can increase the indoor humidity and provide users with a more comfortable environment. Attached Figure Description

[0039] To address the issue that existing air conditioners use outdoor fresh air to increase indoor oxygen levels, but this fresh air causes changes in indoor temperature, leading to reduced user comfort and a negative impact on user experience.

[0040] like Figures 1 to 6As shown in the figure, this embodiment discloses an air conditioner, which includes a casing 1, a heat exchanger, a water collection tray, a humidifying and oxygenating device, and a drain pipe. The humidifying and oxygenating device, the heat exchanger, and the water collection tray are installed inside the casing 1. The humidifying and oxygenating device is located on one side of the water collection tray and is used to supply oxygen and atomized droplets into the room. The water collection tray is located below the heat exchanger and can collect the condensate formed on the surface of the heat exchanger. The inlet end of the drain pipe is connected to the bottom wall of the water collection tray, and the outlet end of the drain pipe extends to the outside. The condensate in the water collection tray is discharged through the drain pipe.

[0041] Specifically, the humidification and oxygenation device includes an electrolysis water oxygen generation unit and a water supply unit. The water supply unit is used to supply water to the electrolysis water oxygen generation unit, which can electrolyze water to produce oxygen and hydrogen.

[0042] like Figures 3 to 5 As shown, the water electrolysis oxygen generation mechanism includes an electrolysis box 31, an anode electrode 32, a cathode electrode 33, an ion exchange membrane 34, a hydrogen discharge pipe 35, a liquid level detection element 36, a first blower 37, and a second blower 38. The electrolysis box 31 is mounted on the housing 1. The water outlet of the water supply mechanism extends into the electrolysis box 31 through the top wall to supply water to the electrolysis box 31. The ion exchange membrane 34 is fixed inside the electrolysis box 31, and a gap is left between the bottom of the ion exchange membrane 34 and the bottom of the electrolysis box 31. The ion exchange membrane 34 can prevent the mixing of oxygen and hydrogen generated by water electrolysis. The ion exchange membrane 34 divides the electrolysis box 31 into an anode chamber 312 and a cathode chamber 313 that are interconnected at the bottom. Since the bottoms of the anode chamber 312 and the cathode chamber 313 are interconnected, the water outlet of the water supply mechanism extends into the anode chamber 312 or the cathode chamber 313, and water can be supplied to the anode chamber 312 and the cathode chamber 313 for electrolysis of the anode electrode 32 and the cathode electrode 33.

[0043] like Figures 1 to 5 As shown, the shell 1 is provided with a first communication port 12, and the electrolysis box 31 is provided with a gas outlet. The gas outlet includes a first gas outlet 311 and a second gas outlet. The first gas outlet 311 is located on the side wall of the anode chamber 312 and is connected to the interior through the first communication port 12. The second gas outlet is located on the side wall of the cathode chamber 313. A hydrogen discharge pipe 35 is fixed in the second gas outlet. The end of the hydrogen discharge pipe 35 away from the electrolysis box 31 extends into the drain pipe.

[0044] like Figures 1 to 4As shown, the anode electrode 32 is inserted into the anode chamber 312, and the cathode electrode 33 is inserted into the cathode chamber 313. Power is supplied to the anode electrode 32 and cathode electrode 33 via the air conditioner's control board; alternatively, an additional power supply can be provided. A liquid level detection element 36 is installed in either the anode chamber 312 or the cathode chamber 313. This element detects the water level within the electrolysis box 31. In this embodiment, the liquid level detection element 36 is a liquid level sensor. When the water level in the electrolysis box 31 falls below a set value, the anode electrode 32 and cathode electrode 33 stop electrolyzing water, reducing the safety hazard caused by dry burning of the anode electrode 32 and cathode electrode 33.

[0045] When energized, the following reactions occur at the anode electrode 32 and the cathode electrode 33, respectively:

[0046] The reaction occurs at anode electrode 32: 4OH - →O2↑+2H2O+4e - ;

[0047] The reaction occurs at cathode electrode 33: 4H₂O + 4e⁻ - →2H₂↑+4OH - ;

[0048] Oxygen generated by the anode electrode 32 enters the room directly through the first outlet 311 and the first connecting port 12, increasing the indoor oxygen content. Compared to oxygenation through fresh air, the oxygenation method in this application has less impact on indoor temperature changes, thereby improving user comfort and providing a better user experience. Hydrogen generated by the cathode is discharged directly outdoors through the hydrogen exhaust pipe 35 and the drain pipe, thereby reducing the indoor hydrogen content and increasing the indoor oxygen content more quickly.

[0049] like Figures 1 to 4 As shown, the first fan 37 is installed on the electrolysis box 31 and connected to the anode chamber 312, and the second fan 38 is installed on the electrolysis box 31 and connected to the cathode chamber 313. During the electrolysis process, starting the first fan 37 and the second fan 38 can supply the oxygen generated by the anode electrode 32 into the room more quickly, increasing the oxygen content in the room, and at the same time, can discharge the hydrogen generated by the cathode electrode 33 to the outside more quickly.

[0050] Furthermore, the air conditioner also includes an oxygen detector and a hydrogen detector. The oxygen detector is installed at the air outlet of the air conditioner or indoors, and can detect the indoor oxygen content. The hydrogen detector can detect the indoor hydrogen content. The hydrogen detector is installed above the air conditioner. Since hydrogen is less dense than air, placing the hydrogen detector above the air conditioner allows for more sensitive and accurate detection of the indoor hydrogen content. In this embodiment, the oxygen detector is an oxygen meter installed at the air outlet of the air conditioner, and the hydrogen detector is a hydrogen meter installed at the air inlet of the air conditioner.

[0051] When the indoor oxygen content is detected to be lower than a first preset value, the indoor hydrogen content is detected to be lower than a second preset value, and the water level in the electrolysis box 31 is not lower than a set value, the first fan 37 and the second fan 38 are activated, and the anode electrode 32 and the cathode electrode 33 are energized to ionize the water in the electrolysis box 31, allowing oxygen to enter the room and increasing the indoor oxygen content. The hydrogen is discharged to the outside through the drain pipe. Preferably, the first preset value is 20%, and the second preset value is 3%.

[0052] When the indoor oxygen content exceeds the third preset value, the indoor hydrogen content exceeds the second preset value, or the water level in the electrolysis box 31 falls below a set value, the first fan 37 and the second fan 38 stop, the anode electrode 32 and the cathode electrode 33 are de-energized, and oxygen production ceases. Preferably, the third preset value is 23%. Furthermore, when the indoor hydrogen content exceeds the preset value, the air conditioner alarms, reminding the user to operate the fresh air mode or open the windows for ventilation to reduce the indoor hydrogen content.

[0053] like Figure 3 and Figure 4 As shown, the water electrolysis oxygen generation mechanism further includes a humidification mechanism 39 and a humidity detection element. The humidity detection element is installed indoors and can detect indoor humidity. The humidification mechanism 39 is installed at the bottom of the anode chamber 312 and can atomize the water in the anode chamber 312. The atomized droplets can enter the room through the first air outlet 311 and the first connecting port 12 to increase indoor humidity. The humidification mechanism 39 can be an ultrasonic humidifier or a heating humidifier. In this embodiment, the humidity detection element is a humidity sensor, and the humidification mechanism 39 is an ultrasonic humidifier. Ultrasonic humidifiers are commonly used devices in the humidification field, and their specific structure will not be described in detail here.

[0054] When the humidity sensor detects that the indoor humidity is lower than the first preset humidity and the water level in the electrolysis box 31 is higher than the set value, the ultrasonic humidifier and the first fan 37 are activated. The ultrasonic transducer of the ultrasonic humidifier disperses water molecules through high-frequency vibration, forming atomized droplets. The first fan 37 then directs these atomized droplets into the room through the first air outlet 311 and the first connecting port 12, increasing the indoor humidity and making the user more comfortable. When the indoor humidity is higher than the second preset humidity or the water level in the electrolysis box 31 is lower than the set value, the ultrasonic humidifier and the first fan 37 stop. The first preset humidity is lower than the second preset humidity.

[0055] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the water supply mechanism includes a water tank 41, a liquid seal pipe 42, and a sealing assembly. An mounting plate 2 is fixed inside the housing 1 above the electrolysis box 31. The water tank 41 is placed on the mounting plate 2. The top of the water tank 41 has an inlet, which is fitted with a cover plate. An outlet 411 is located on the side wall of the water tank 41. The sealing assembly is located inside the water tank 41 and is used to seal the outlet 411. The housing 1 has an installation port 11, on which a baffle 13 is attached to block the installation port 11. Removing the baffle 13 allows the user to remove the water tank 41 through the installation port 11, facilitating water replenishment. The baffle 13 has a second connecting port 131. The first air outlet 311 connects to the indoor environment through the first connecting port 12 and the second connecting port 131, allowing oxygen and atomized droplets to directly enter the room.

[0056] The inlet end of the liquid seal pipe 42 can be inserted into the outlet 411, and the outlet end of the liquid seal pipe 42 extends through the top of the electrolysis box 31 and into the electrolysis box 31. There is a liquid level maintaining gap between the outlet end of the liquid seal pipe 42 and the bottom of the electrolysis box. This liquid level maintaining gap is greater than the set value of the water level in the electrolysis box 31, so that when there is water in the water supply tank 41, the humidification and oxygenation device can stably ionize water or atomize water. Preferably, the value of the liquid level maintaining gap is in the range of 15mm-25mm.

[0057] When the user removes the water supply tank 41, the inlet end of the liquid seal pipe 42 is pulled out from the outlet 411, the sealing assembly seals the outlet 411, and the liquid seal pipe 42 is disconnected from the water supply tank 41. When the user fills the water supply tank 41 with water, the water supply tank 41 is placed on the mounting plate 2, and the inlet end of the liquid seal pipe 42 is inserted into the outlet 411. At this time, the sealing assembly no longer seals the outlet 411, and the liquid seal pipe 42 is connected to the water supply tank 41.

[0058] like Figure 5As shown, the sealing assembly includes a sealing plug 431 made of rubber. When the user replenishes water to the water supply tank 41, the sealing plug 431 is first inserted into the outlet 411 through the inlet to seal the outlet 411, and then water is replenished to the water supply tank 41. After replenishment, the cover is closed, the water supply tank 41 is placed on the mounting plate 2, and the inlet end of the liquid seal pipe 42 is inserted into the outlet 411. During the insertion of the liquid seal pipe 42, the sealing plug 431 is pushed into the water supply tank 41, connecting the liquid seal pipe 42 with the water supply tank 41, thus replenishing water to the electrolysis box 31.

[0059] like Figure 6 As shown, in another preferred embodiment, the sealing assembly includes a sealing plate 432, a sealing gasket 433, and an elastic element 434. The rubber sealing gasket 433 is adhered to the sealing plate 432. The elastic element 434 is a torsion spring. The first leg of the torsion spring is fixed to the water outlet 411, and the second leg of the torsion spring is fixed to the sealing plate 432. Under the elastic force of the torsion spring, the sealing gasket 433 presses against the water outlet 411 to seal the water outlet 411. When the user removes the water tank 41, the sealing gasket 433 automatically seals the water outlet 411 under the action of the elastic force, which is more convenient than the user manually inserting the sealing plug 431 into the water outlet 411. After water replenishment is completed, place the water supply tank 41 on the mounting plate 2 and insert the inlet end of the liquid seal pipe 42 into the outlet 411. During the insertion of the liquid seal pipe 42, push open the sealing gasket 433 and the sealing plate 432 to connect the liquid seal pipe 42 with the water supply tank 41 and replenish water to the electrolysis box 31.

[0060] During operation, when the water in the anode chamber 312 is electrolyzed or atomized, the water level decreases. Water stored in the water supply tank 41 flows into the anode chamber 312 by gravity. When the water level in the anode chamber 312 rises to the outlet end of the liquid seal pipe 42, atmospheric pressure causes the water in the water supply tank 41 to stop flowing, maintaining the water level in the anode chamber 312 at the outlet end of the liquid seal pipe 42. This allows the humidification and oxygenation device to stably ionize or atomize water. When the water level in the anode chamber 312 is detected to be lower than the set value, it indicates that the water supply tank 41 needs replenishment, triggering an alarm on the air conditioner to remind the user to replenish the water supply tank 41 promptly. Compared to replenishing the anode chamber 312 with electric components such as a water pump, the liquid seal pipe 42 requires no electricity and less maintenance, making it more energy-efficient and convenient.

[0061] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
