[0050] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] Please refer to Figures 1 to 17 The air conditioner indoor unit 10 includes a housing 100 , and the housing 100 is provided with a first opening 111 and a second opening 112 .

[0052] The air conditioner indoor unit 10 includes a fresh air module and an oxygen production module 300. The fresh air module and the oxygen production module 300 are used to adjust the indoor environment.

[0053] The fresh air module is disposed within the housing 100 and is used to connect the indoor environment with the outdoor environment. The fresh air module includes a polluted air inlet 210 for communicating with the first opening 111. The fresh air module connects the indoor and outdoor environments. When the indoor environment is relatively polluted, polluted air in the indoor environment is introduced into the fresh air module through the first opening 111 and the polluted air inlet 210, and then discharged into the room.

[0054] The oxygen production module 300 is disposed within the housing 100 and is configured to provide oxygen to the indoor environment. The oxygen production module 300 includes an oxygen production outlet 310 for communicating with the second opening 112. The oxygen production module 300 sequentially provides oxygen to the indoor environment through the oxygen production outlet 310 and the second opening 112, thereby increasing the oxygen concentration in the indoor environment.

[0055] In some embodiments, the air conditioner indoor unit 10 further includes a heat exchanger, which exchanges heat for the airflow passing through the heat exchanger and then sends the heat to the indoor environment through a heat exchange outlet. The second opening 112 is connected to the heat exchange outlet.

[0056] The first opening 111 and the second opening 112 of the air conditioner indoor unit in the present invention are separated by a predetermined distance to prevent the oxygen discharged from the second opening 112 from entering the first opening 111, thereby solving the problem in the prior art that the fresh air device easily discharges the oxygen provided by the oxygen generator to the outside.

[0057] In some embodiments, the fresh air module and the oxygen production module 300 are arranged on the outside of the air conditioner indoor unit 10, and the dirty air inlet 210 of the fresh air module and the oxygen production outlet 310 of the oxygen production module 300 are separated by a predetermined distance to prevent oxygen discharged from the oxygen production outlet 310 from entering the dirty air inlet 210.

[0058] In some embodiments, the oxygen production module 300 may produce oxygen by electronic oxygen production, molecular sieve oxygen production, chemical oxygen production, or oxygen-enriched membrane oxygen production.

[0059] In some embodiments, the housing 100 includes a first side panel 120 and a second side panel 130 . The fresh air module is located at one end of the housing 100 near the first side panel 120 , and the oxygen production module 300 is located at one end of the housing 100 near the second side panel 130 .

[0060] Figure 1 FIG. 1 is a structural diagram of an air conditioner indoor unit 10 according to an embodiment of the present invention. Figure 2 FIG. 1 shows a schematic structural diagram of an air conditioner indoor unit 10 according to an embodiment of the present invention. Figure 1 and Figure 2 When the first side panel 120 is the left panel and the second side panel 130 is the right panel, the fresh air module is located on the left side of the air conditioner indoor unit 10 and the oxygen production module 300 is located on the right side of the air conditioner indoor unit 10 .

[0061] See also Figure 1 The first opening 111 and the second opening 112 are both provided on the top plate 140 of the housing 100. That is, the air intake mode of the fresh air module is top air intake, and the air outlet mode of the oxygen production module 300 is top air outlet.

[0062] In some embodiments, along the length direction of the housing 100, the top plate 140 has a first end 141 and a second end 142. Figure 1 , the first end 141 may be the left end of the top plate 140 , and the second end 142 may be the right end of the top plate 140 .

[0063] When the first opening 111 and the second opening 112 are both provided on the top plate 140 of the housing 100, along the length direction of the housing 100, the distance between the first opening 111 and the outer edge of the first end portion 141 is less than or equal to one-fifth of the length of the top plate 140; and along the length direction of the housing 100, the distance between the second opening 112 and the outer edge of the second end portion 142 is less than or equal to one-fifth of the length of the top plate 140. In other words, along the length direction of the housing 100, the distance between the first opening 111 and the second opening 112 is greater than or equal to three-fifths of the length of the top plate 140.

[0064] Figure 3 FIG. 1 shows a structural diagram of an oxygen production module 300 in an air conditioner indoor unit 10 according to an embodiment of the present invention. Figure 3 The oxygen production module 300 further includes an oxygen production module housing 320 .

[0065] See also Figure 3As can be seen, the oxygen production module housing 320 is provided with an oxygen production air inlet 330 and an oxygen production air outlet 310. The oxygen production air inlet 330 is used to allow air from the indoor environment to enter the oxygen production module 300, and the oxygen production air outlet 310 is used to allow oxygen in the oxygen production module 300 to flow out.

[0066] In some embodiments, the air conditioner indoor unit 10 further includes an electrical box. The distance between the oxygen production module housing 320 and the electrical box is smaller than the distance between the fresh air module and the electrical box.

[0067] In some embodiments, the oxygen production module 300 is disposed above, below, to the left, to the right, or inside the electrical enclosure. Since the oxygen production module 300 is connected to a power cord that extends into the electrical enclosure, locating the oxygen production module 300 near the electrical enclosure facilitates wiring, shortens the power cord routing distance, avoids power cord wiring clutter, and reduces the probability of electrical accidents in the air conditioner indoor unit 10.

[0068] Meanwhile, if the oxygen production module 300 adopts an electronic oxygen production method, arranging the oxygen production module 300 near the electrical box can prevent signal attenuation, thereby achieving the effects of stable electrical transmission and signal stability.

[0069] Figure 17 FIG. 1 shows a schematic structural diagram of an oxygen generator of an air conditioner indoor unit 10 according to another embodiment of the present invention. Figure 17 The oxygen production module housing 320 is provided with a wiring portion 500. The power cord for the electrolysis device 340 of the oxygen production module 300 extends from the oxygen production module housing 320 and then into the electrical box. A positioning groove for positioning the power cord is formed between the wiring portion 500 and the outer surface of the oxygen production module housing 320. Due to the limited space inside the air conditioner indoor unit 10, a loose wiring may cause noise or electrical safety accidents. Therefore, the power cord is placed in the positioning groove of the wiring portion 500. This effectively prevents the power cord of the oxygen production device from becoming entangled with other components or wires inside the air conditioner indoor unit 10, which may cause electrical accidents.

[0070] Figure 14 FIG1 shows a schematic structural diagram of an electrolysis device of an air conditioner indoor unit according to an embodiment of the present invention. Figure 14 The oxygen production module 300 further includes an electrolysis device 340 . The electrolysis device 340 is disposed within the oxygen production module housing 320 , so that ambient air entering from the oxygen production air inlet 330 passes through the electrolysis device 340 and then flows out from the oxygen production air outlet 310 .

[0071] See also Figure 14 The electrolysis device 340 includes a first clamping portion 342 . The first clamping portion 342 is protruded from the outer surface of the electrolysis device 340 .

[0095] In some embodiments, there is at least one protrusion 3616 and at least one buckle 3621 , and the at least one protrusion 3616 and the at least one buckle 3621 are provided in a one-to-one correspondence.

[0096] During the specific implementation process, the protrusion 3616 is snapped into the snap hole on the buckle 3621 to achieve a detachable connection between the first filter membrane bracket 361 and the second filter membrane bracket 362. When it is necessary to remove the second filter membrane 350 between the first filter membrane bracket 361 and the second filter membrane bracket 362, the first filter membrane bracket 361 and the second filter membrane bracket 362 can be disassembled and then the second filter membrane 350 can be replaced.

[0097] See also Figure 17 The oxygen production module 300 further includes a first filter membrane 341. The first filter membrane 341 is disposed in the electrolysis device 340 and is used to filter the rare gases in the ambient air.

[0098] In some embodiments, the first filter membrane 341 is a one-way selective filter membrane, and other rare gases in the air gas components cannot pass through the first filter membrane 341 .

[0099] See also Figure 4 The second filter membrane 350 and the first filter membrane 341 divide the oxygen production module shell 320 into a first cavity portion, a second cavity portion and a third cavity portion. The first cavity portion is connected to the oxygen production air inlet 330, and the third cavity portion is connected to the oxygen production outlet 310.

[0100] See also Figure 12 The oxygen production module bracket 324 is provided with a plurality of first exhaust holes 371, which are connected to the first cavity portion to discharge the gas in the first cavity portion. Nitrogen that cannot pass through the second filter membrane 350 can be discharged from the oxygen production module 300 through the first exhaust holes 371.

[0101] The oxygen production module 300 includes a plurality of first baffle assemblies, which are arranged in a one-to-one correspondence with the plurality of first exhaust holes 371 , so that the corresponding first exhaust hole 371 is opened or closed by each first baffle assembly.

[0102] The oxygen production module 300 includes a first pressure sensor 372 , which is used to detect the gas pressure in the first cavity portion, so as to control the opening or closing of the plurality of first baffle assemblies according to the gas pressure in the first cavity portion.

[0103] Figure 16 FIG. 3 is a structural diagram of an oxygen production module cover 325 of an air conditioner indoor unit 10 according to another embodiment of the present invention. Figure 15 and Figure 16 The oxygen production module cover 325 is provided with a plurality of second exhaust holes 381, which are connected to the second cavity portion to discharge the gas in the second cavity portion. Other rare gases that cannot pass through the first filter membrane 341 can be discharged from the oxygen production module 300 through the second exhaust holes 381.

[0104] The oxygen production module 300 includes a plurality of second baffle assemblies, which are arranged in a one-to-one correspondence with the plurality of second exhaust holes 381 , so that the corresponding second exhaust holes 381 are opened or closed by each second baffle assembly.

[0105] The oxygen production module 300 includes a second pressure sensor 382 , which is used to detect the gas pressure in the second cavity portion, so as to control the opening or closing of the plurality of second baffle assemblies according to the gas pressure in the second cavity portion.

[0106] See also Figure 16 A plurality of third drainage holes 391 are formed on the oxygen production module cover 325 , and the plurality of third drainage holes 391 are connected to the third cavity portion to discharge the liquid in the third cavity portion.

[0107] The oxygen production module 300 includes a plurality of third baffle assemblies, which are arranged in a one-to-one correspondence with the plurality of third drainage holes 391 , so that the corresponding third drainage holes 391 are opened or closed by each third baffle assembly.

[0108] The oxygen production module 300 includes a third liquid pressure sensor, which is used to detect the liquid pressure in the third cavity portion to control the opening or closing of the plurality of third baffle assemblies according to the liquid depth in the third cavity portion.

[0109] In a specific implementation process, each of the first drain hole, the second drain hole and the third drain hole 391 is connected to a drain pipe 400 to discharge gas or liquid out of the oxygen production module 300 .

[0110] In some embodiments, the distance between the cathode of the electrolysis device 340 and the second filter membrane 350 is smaller than the distance between the anode and the second filter membrane 350. That is, the air in the indoor environment passes through the oxygen production air inlet 330, the first exhaust hole 371, the second filter membrane 350, the second exhaust hole 381, the cathode of the electrolysis device 340, the first filter membrane 341, the anode of the electrolysis device 340, the third drain hole 391 and the oxygen production outlet 310 in sequence.

[0111] Reaction at the cathode: 2H2O+O2+4e→4OH — 、H2O+O2+2e→OH — +HO2 — ;

[0112] Reaction at the anode: 4OH-4e→2H2O+O2(pure)↑, OH — +H2O-2e→H2O+O2(pure)↑;

[0113] The water produced by the electrolysis device 340 can flow out of the oxygen production module 300 through the third drain hole 391, and the pure oxygen produced by the electrolysis device 340 can be delivered to the indoor environment through the oxygen production outlet 310. After the air conditioner indoor unit 10 is turned on in the specific mode, it activates the oxygen production mode, and the oxygen production module 300 operates to produce pure, pollution-free oxygen, thereby improving the indoor air quality caused by the decrease in indoor oxygen concentration and the discomfort caused to the user.

[0114] The air conditioner includes an indoor unit 10. The indoor unit 10 is the same as that described in the above embodiment, and the oxygen production module 300 is fixedly connected to the bottom housing of the indoor unit 10. Adding the fresh air module and the oxygen production module 300 to the indoor unit 10 and spacing the first opening 111 and the second opening 112 on the housing 100 of the indoor unit 10 at a relatively large distance effectively prevents some or all of the oxygen produced by the oxygen production module 300 from being drawn into the fresh air module and discharged indoors without being circulated indoors, thereby failing to improve the indoor air quality.

[0115] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0116] The housing 100 of the air conditioner indoor unit 10 houses a fresh air module and an oxygen production module 300, which are used to regulate the indoor environment. The fresh air module connects the indoor and outdoor environments. When the indoor environment is relatively polluted, polluted air in the indoor environment is introduced into the fresh air module through the polluted air inlet 210 and then discharged indoors. The oxygen production module 300 provides oxygen to the indoor environment through the oxygen production outlet 310 to increase the oxygen concentration in the indoor environment. The housing 100 is provided with a first opening 111, which communicates with the polluted air inlet 210, and a second opening 112, which communicates with the oxygen production outlet 310. The first opening 111 and the second opening 112 are separated by a predetermined distance to prevent oxygen discharged from the second opening 112 from entering the first opening 111. This solves the problem in the prior art where fresh air devices easily discharge oxygen provided by the oxygen production device outdoors.
