For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] In order to solve the problem that the indoor oxygen is usually increased by introducing outdoor fresh air, but a large amount of introduced fresh air will change the indoor environment temperature, resulting in reduced user comfort and affecting user experience.

[0035] As shown in Figure 1 The present embodiment discloses an air conditioner, which comprises a shell and a fresh air module 2, the shell comprises a face frame 11 and a front panel, the front panel is detachably mounted on the face frame 11, and the fresh air module 2 is located in the cavity formed by the front panel and the face frame 11 and is mounted on the face frame 11.

[0036] As shown in Figures 1 to 3As shown, specifically, the fresh air module 2 includes a shell 21, a fan 22, a fresh air pipe 23, a mounting rack 25 and an oxygen increasing mechanism 24 for manufacturing oxygen, the shell 21 is installed in the cavity, a first end of the fresh air pipe 23 is in communication with the shell 21, a second end of the fresh air pipe 23 extends to the outdoor, and a wind valve is further installed on the fresh air pipe 23, by opening and closing the wind valve, whether the outdoor air can enter the shell 21 can be controlled. The fan 22 is installed at the end of the shell 21, and the shell is provided with a fresh air port, the fan 22 can supply the outdoor air into the indoor through the fresh air pipe 23, the shell 21, the air inlet of the fan 22, the air outlet of the fan 22 and the fresh air port, or can reversely discharge the indoor air to the outdoor through the fresh air pipe 23.

[0037] After the oxygen increasing mechanism 24 and the fan 22 are started, the fan 22 supplies the outdoor air and the oxygen manufactured by the oxygen increasing mechanism 24 into the indoor, and the oxygen content in the indoor is improved. By manufacturing the oxygen through the oxygen increasing mechanism 24, the oxygen content in the fresh air can be improved, so that the amount of the fresh air introduced into the indoor can be reduced, the influence of the fresh air on the indoor temperature is reduced, and then the comfort of the user is improved, and the user has a better use experience.

[0038] As shown in the figure, Figures 1 to 5 The shell 21 is provided with a mounting port 211 at the air inlet side of the fan 22, a support plate 26 is fixed on the inner wall of the shell 21, the mounting rack 25 is slidingly arranged in the mounting port 211, and the bottom of the mounting rack 25 is placed on the support plate 26, and the user can take out or put the mounting rack 25 into the shell 21 through the mounting port 211. The mounting rack 25 includes a sealing plate 251 and a placing rack 252 fixed on the sealing plate 251, the placing rack 252 is placed on the support plate 26, and the oxygen increasing mechanism 24 is placed in the placing rack 252. In the embodiment, the placing rack 252 is hollow, which can reduce the air resistance when the fluid passes through the placing rack 252, and when the mounting rack 25 is inserted into the mounting port 211, the sealing plate 251 closes the mounting port 211, which can reduce the possibility of gas leakage from the mounting port 211. When the oxygen increasing mechanism 24 needs to be overhauled or maintained, the front panel is first taken off from the face frame 11, and then the mounting rack 25 is taken out from the mounting port 211, so that the oxygen increasing mechanism 24 can be taken out from the shell 21, which has good operation convenience.

[0039] As shown in the figure, Figure 4 and Figure 5As shown, the oxygen increasing mechanism 24 comprises an electrolytic box 240, an anode electrode 243, a cathode electrode 244, an ion exchange membrane 245 and a liquid level detecting piece 248. The electrolytic box 240 is placed in the mounting frame 25, and the top of the electrolytic box 240 is provided with a water inlet 2401 through which the user can manually supplement water in the electrolytic box 240. The ion exchange membrane 245 is fixed in the electrolytic box 240, and a space is left between the bottom of the ion exchange membrane 245 and the bottom of the electrolytic box 240. The ion exchange membrane 245 can hinder the mixing of oxygen and hydrogen generated by electrolysis of water, and the electrolytic box 240 is divided into an anode chamber 241 and a cathode chamber which are in communication with each other at the bottom by the ion exchange membrane 245. Since the anode chamber 241 and the cathode chamber are in communication with each other at the bottom, water can be supplied into the anode chamber 241 and the cathode chamber through the water inlet 2401 which is in communication with the anode chamber 241 or the cathode chamber, for electrolysis by the anode electrode 243 and the cathode electrode 244. In this embodiment, the water inlet 2401 is in communication with the anode chamber 241.

[0040] The electrolytic box 240 is provided with a plurality of first gas outlets 2402 and second gas outlets 2403. The first gas outlets 2402 are arranged on the side wall of the anode chamber 241, and the second gas outlets 2403 are arranged on the top wall of the cathode chamber. The anode electrode 243 is inserted into the anode chamber 241, and the cathode electrode 244 is inserted into the cathode chamber. The anode electrode 243 and the cathode electrode 244 are powered by the control panel of the air conditioner, or an additional power supply can be additionally arranged to power the anode electrode 243 and the cathode electrode 244.

[0041] After the anode electrode 243 and the cathode electrode 244 are powered, the following reactions occur at the anode electrode 243 and the cathode electrode 244, respectively:

[0042] The reaction occurring at the anode electrode 243 is: 4OH - → O2↑ + 2H2O + 4e - ;

[0043] The reaction occurring at the cathode electrode 244 is: 4H2O + 4e - → 2H2↑ + 4OH - ;

[0044] The oxygen generated by the anode electrode 243 enters the shell 21 through the first gas outlets 2402, and the hydrogen generated by the cathode electrode 244 enters the shell 21 through the second gas outlets 2403. Under the action of the fan 22, the oxygen and the hydrogen enter the indoor space together with the outdoor fresh air to increase the oxygen content in the indoor space. Since the oxygen generated by the anode electrode 243 can increase the oxygen content in the fresh air, the amount of fresh air required to provide the same oxygen content in the indoor space is reduced, thereby reducing the influence of the fresh air on the indoor temperature and improving the comfort of the user to provide a better user experience.

[0045] As Figure 4 and Figure 5 Further, the oxygen increasing mechanism 24 further comprises a grid 247 and an adsorption assembly 246, the grid 247 divides the cathode chamber into an adsorption cavity 2421 and an ionization cavity 2422 in communication from top to bottom, the second gas outlet 2403 is in communication with the adsorption cavity 2421, the cathode electrode 244 is located in the ionization cavity 2422, and the adsorption assembly 246 is located in the adsorption cavity 2421. Since hydrogen has a small density, placing the adsorption assembly 246 in the adsorption cavity 2421 above can enable the adsorption assembly 246 to better adsorb hydrogen. The adsorption assembly 246 comprises at least one of carbon-based particles, metal organic frameworks, and zeolites, all of which have the characteristic of high porosity and can adsorb hydrogen. Specifically, the carbon-based particles comprise one of activated carbon and graphene, and the adsorption assembly 246 in the embodiment is activated carbon particles for economic considerations.

[0046] Placing activated carbon particles in the adsorption cavity 2421 can reduce the hydrogen content entering the room, thereby more quickly increasing the oxygen content in the room, and further reducing the amount of fresh air introduced into the room, thereby reducing the impact of fresh air on the temperature in the room. As the use time of the activated carbon particles extends, the hydrogen that is not adsorbed enters the shell 21 through the second gas outlet 2403, which can reduce the safety hazards caused by hydrogen accumulation. When the activated carbon particles need to be replaced or the electrolysis box 240 needs to be refilled, the user can remove the mounting bracket 25 and the oxygen increasing mechanism 24 from the mounting port 211. When replacing the activated carbon particles, the second gas outlet 2403 can be used for replacement, or a refilling port can be provided on the top wall of the adsorption cavity 2421 to improve the convenience of replacing the activated carbon particles.

[0047] As Figure 5 shown, the liquid level detection member 248 is installed in the anode chamber 241 or the cathode chamber, and the liquid level detection member 248 can detect the water level in the electrolysis box 240. In the embodiment, the liquid level detection member 248 is a liquid level sensor. When the water level in the electrolysis box 240 is between a first preset water level and a second preset water level, the first preset water level is lower than the second preset water level, and the anode electrode 243 and the cathode electrode 244 can be powered to electrolyze water. When the water level in the electrolysis box 240 is lower than the first preset water level, the anode electrode 243 and the cathode electrode 244 stop electrolyzing water, thereby reducing the safety hazards caused by dry burning of the anode electrode 243 and the cathode electrode 244.

[0048] Further, the air conditioner further comprises an oxygen detection member and a hydrogen detection member, the oxygen detection member is installed at an air outlet of the air conditioner or installed indoors, and the oxygen detection member can detect an oxygen content in the room. The hydrogen detection member can detect a hydrogen content in the room, and the hydrogen detection member is installed above the air conditioner, since the hydrogen has a smaller density than air, the hydrogen detection member is arranged above the air conditioner, so that the hydrogen content in the room can be detected more sensitively and accurately. In the embodiment, the oxygen detection member is an oxygen detector, the oxygen detector is installed at the air outlet of the air conditioner, the hydrogen detection member is a hydrogen detector, and the hydrogen detection member is installed at an air inlet of the air conditioner.

[0049] When it is detected that the oxygen content in the room is lower than a first preset value, the hydrogen content in the room is lower than a second preset value, and the first preset water level < the water level in the electrolytic box < the second preset water level, the fan 22 is started, the anode electrode 243 and the cathode electrode 244 are powered on, the water in the electrolytic box 240 is ionized, the oxygen enters the shell 21 through the first gas outlet 2402, enters the room together with the outdoor fresh air under the action of the fan 22, the oxygen content in the room is increased, and the hydrogen is adsorbed by the adsorption assembly 246. Preferably, the first preset value is 20%, and the second preset value is 3%.

[0050] When the oxygen content in the room is higher than a third preset value, the hydrogen content in the room is higher than the second preset value or the water level in the electrolytic box 240 is lower than the first preset water level, the fan 22 is stopped, the anode electrode 243 and the cathode electrode 244 are powered off, and the oxygen production is stopped. Preferably, the third preset value is 23%.

[0051] When it is detected that the oxygen content in the room is lower than the first preset value, the hydrogen content in the room is lower than the second preset value, and the water level in the electrolytic box 240 is lower than the first preset water level, the fan 22 is started, the outdoor fresh air is introduced into the room to increase the oxygen content in the room, and the air conditioner alarms to remind a user to add water to the electrolytic box 240.

[0052] In addition, when the hydrogen content in the room is higher than the second preset value, the air conditioner alarms to remind the user to start the fan 22 to reverse, to exhaust the indoor air with a higher hydrogen content to the outdoor, or to open a window to ventilate, so as to reduce the hydrogen content in the room.

[0053] The technical scheme of the air conditioner has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the air conditioner is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the air conditioner, and the technical schemes after the changes or replacements will all fall within the protection scope of the air conditioner.
