[0033] As Figure 1 And Figure 2 The embodiment discloses an air conditioner, which comprises a shell 1, a heat exchanger, a water pan 2, an electrolytic water oxygen generating device and a drain pipe 3, the heat exchanger and the water pan 2 are installed in the shell 1, and the water pan 2 is located below the heat exchanger and can receive the condensed water formed on the surface of the heat exchanger. The water inlet of the drain pipe 3 is communicated with the side wall of the water pan 2, and the water outlet of the drain pipe 3 extends to the outdoor. When the liquid level of the condensed water in the water pan 2 exceeds the water inlet of the drain pipe 3, the condensed water is discharged through the drain pipe 3. The electrolytic water oxygen generating device is installed in the drain pipe 3, and the water flowing through the drain pipe 3 is electrolyzed by the electrolytic water oxygen generating device, so that the generated oxygen can enter the indoor, and the oxygen content in the indoor is improved.

[0034] As Figure 1 The drain pipe 3 comprises a first drain section 31, a hydrogen discharge section 32 and a second drain section 33, a drain interface is integrally formed on the side wall of the water pan 2, the water inlet of the first drain section 31 is matched and arranged outside the drain interface, and is detachably connected to the water pan 2 through the first screw, the water outlet of the first drain section 31 is communicated with the hydrogen discharge section 32, and preferably, the first drain section 31 and the hydrogen discharge section 32 are integrally formed. The water inlet of the second drain section 33 is communicated with the water outlet of the hydrogen discharge section 32, and the water outlet of the second drain section 33 extends to the outdoor. The second drain section 33 is adhesively fixed on the hydrogen discharge section 32, and of course, can be arranged in a detachable connection mode, so as to facilitate the maintenance of the electrolytic water oxygen generating device. In the embodiment, the second drain section 33 is made of flexible material, which facilitates the second drain section 33 to pass through the hole reserved in the wall, and reduces the installation difficulty.

[0035] The inner diameter of the first water draining section 31 is smaller than that of the hydrogen exhausting section 32, and the inner diameter of the second water draining section 33 is the same as that of the first water draining section 31. When the water level in the water pan 2 exceeds the water inlet of the water draining pipe 3, the condensed water flows through the first water draining section 31, the hydrogen exhausting section 32 and the second water draining section 33 in turn and is drained to the outside. The inclination angle of the first water draining section 31 and the hydrogen exhausting section 32 is 15-40°, and preferably, the inclination angle of the water draining interface, the first water draining section 31 and the hydrogen exhausting section 32 is all 20°, so that the condensed water in the water pan 2 can flow out smoothly, the flow rate in the first water draining section 31 and the hydrogen exhausting section 32 can be reduced, the contact time of the water flow with the electrolytic water oxygen generating device can be prolonged, and the efficiency of the electrolytic water can be improved.

[0036] As shown in Figure 1 , the electrolytic water oxygen generating device comprises an anode electrode 41, a cathode electrode 42, a hydrogen exhausting pipe 43 and a flow rate detecting member 44. The flow rate detecting member 44 is installed on the inner wall of the first water draining section 31 and is used for detecting the flow rate of the water flow. When the flow rate of the water flow in the water draining pipe 3 is not greater than a preset flow rate, the anode electrode 41 and the cathode electrode 42 stop being powered, so as to prevent dry burning. In the embodiment, the flow rate detecting member 44 is a flow rate meter, which is a commonly used device in the art, and the specific structure is not described herein. The hydrogen exhausting section 32 is provided with a hydrogen exhausting port on the side wall away from the water flow, and the hydrogen exhausting pipe 43 is fixed in the hydrogen exhausting port. The end of the hydrogen exhausting pipe 43 away from the hydrogen exhausting section 32 extends to the outside through a hole reserved in the wall.

[0037] As shown in Figure 1 , the electrolysis section of the anode electrode 41 is located in the water inlet of the first water draining section 31, and the wiring section of the anode electrode 41 extends out through the side wall of the first water draining section 31. The electrolysis section of the cathode electrode 42 is located in the hydrogen exhausting section 32, and the wiring section of the cathode electrode 42 extends out through the side wall of the hydrogen exhausting section 32. The wiring sections of the anode electrode 41 and the cathode electrode 42 are powered by the control panel of the air conditioner, and of course, an additional power source can also be provided to power the wiring sections of the anode electrode 41 and the cathode electrode 42. After the anode electrode 41 and the cathode electrode 42 are powered, the following reactions occur at the anode electrode 41 and the cathode electrode 42, respectively.

[0038] The reaction occurring at the anode electrode 41 is: 4OH - → O2↑ + 2H2O + 4e - ;

[0039] The reaction occurring at the cathode electrode 42 is: 4H2O + 4e - → 2H2↑ + 4OH - ;

[0040] As shown in Figure 1As shown, further, the electrolytic segments of the anode electrode 41 and the cathode electrode 42 are provided in a spiral shape, which can increase the contact area of the anode electrode 41 and the cathode electrode 42 with water and improve the efficiency of electrolysis of water. The electrolytic segments of the anode electrode 41 and the cathode electrode 42 are further coated with a catalytic layer. Preferably, the electrolytic segment of the anode electrode 41 is coated with a transition metal oxide layer, which can improve the efficiency of electrolysis of water to generate oxygen; and the electrolytic segment of the cathode electrode 42 is coated with a transition metal compound layer, which can improve the efficiency of electrolysis of water to generate hydrogen. The catalytic layer can further improve the efficiency of electrolysis of water, thereby more quickly increasing the oxygen content in the room.

[0041] The electrolytic segment of the anode electrode 41 is located in the water inlet of the first drainage segment 31. The oxygen generated by the anode electrode 41 enters the housing 1 under the action of the fan of the air conditioner and enters the room through the air outlet of the housing 1, thereby increasing the oxygen content in the room. Moreover, compared with increasing oxygen by fresh air, the oxygen increasing mode in the present application has less effect on the change of indoor temperature, thereby improving the comfort of the user and providing the user with a better use experience. Since hydrogen has a small density and is easy to separate from water and rise, and the inner diameter of the first drainage segment 31 is smaller than the inner diameter of the hydrogen discharge segment 32, the hydrogen can be prevented from entering the first drainage segment 31, so that the generated hydrogen can be discharged to the outdoor through the hydrogen discharge pipe 43, thereby reducing the hydrogen content in the room and more quickly increasing the oxygen content in the room.

[0042] Further, the air conditioner further comprises an oxygen detection member and a hydrogen detection member. The oxygen detection member is installed at the air outlet of the air conditioner or in the room, and the oxygen content in the room can be detected by the oxygen detection member. The hydrogen detection member can detect the hydrogen content in the room, and the hydrogen detection member is installed above the air conditioner. Since 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 more sensitively and accurately detected. In the present embodiment, the oxygen detection member is an oxygen detector, which is installed at the air outlet of the air conditioner, and the hydrogen detection member is a hydrogen detector, which is installed at the air inlet of the air conditioner.

[0043] When the air conditioner runs in the cooling mode, the heat exchanger surface produces more condensate water, and the condensate water flows into the water pan 2. When the air conditioner runs in the cooling mode, it is detected that the indoor oxygen content is lower than the first preset value, the indoor hydrogen content is lower than the second preset value, and the water flow velocity in the drain pipe 3 is greater than the preset speed, the electrolytic water oxygen generator is powered on, and the condensate water flowing through the drain pipe 3 is ionized, so that oxygen can enter the indoor, increase the indoor oxygen content, and hydrogen is discharged to the outdoor through the hydrogen discharge pipe 43. Preferably, the first preset value is 20%, the second preset value is 3%, and when the indoor oxygen content is greater than the third preset value, the indoor hydrogen content is greater than the second preset value, and the water flow velocity in the drain pipe 3 is not greater than the preset speed or the air conditioner no longer runs in the cooling mode, the electrolytic water oxygen generator is powered off and stops oxygen production. Preferably, the third preset value is 23%, and when the indoor hydrogen content is greater than the second preset value, the air conditioner alarms to remind the user to run the fresh air mode or open the window to ventilate to reduce the indoor hydrogen content.

[0044] The condensate water is collected by the water pan 2, and the condensate water is used as the water source for electrolytic water, which can reduce the frequency of the user replenishing water to the water pan 2, make the oxygen production process of the electrolytic water oxygen generator more convenient, the cost is also lower, and the discharge amount of the condensate water can be reduced.

[0045] As shown in Figure 1 and Figure 2 Further, the air conditioner further comprises a water replenishing device, the water replenishing device comprises a water replenishing tank 51, a water replenishing pipe 52, a water replenishing valve 53 and a drain valve 34, the water replenishing tank 51 is installed indoors and the bottom of the water replenishing tank 51 is higher than the water pan 2. In this embodiment, the water replenishing tank 51 is made of glass or transparent plastic material, so that the user can observe the water level in the water replenishing tank 51 and replenish water in the water replenishing tank 51 in time. One end of the water replenishing pipe 52 is communicated with the bottom of the water replenishing tank 51, the other end of the water replenishing pipe 52 extends to above the water pan 2 through the shell 1, the water replenishing valve 53 is installed on the water replenishing pipe 52, and the water replenishing valve 53 is an electromagnetic valve which can be controlled to open or close by the control panel.

[0046] The drain valve 34 is installed on the drain pipe 3 and located downstream of the cathode electrode 42. In this embodiment, the drain valve 34 is installed on the second drain section 33, and the drain valve 34 is an electromagnetic valve which can be controlled to open or close by the control panel. The electrolytic water oxygen generator further comprises a liquid level detector 45 installed in the water pan 2 for detecting the water level in the water pan 2.

[0047] When the air conditioner runs in the heating mode, the heat exchanger surface does not produce condensate water, and the water in the water receiving tray 2 can be supplemented by the water supplementing device, so that the electrolytic water oxygen generating device can increase the oxygen in the room. When the water level in the water receiving tray 2 is lower than the first set value, the water in the water supplementing tank 51 flows to the water receiving tray 2 by gravity, and when the water level in the electrolytic tank is higher than the second set value, the water supplementing valve 53 is closed and the water supplementing is stopped. The lower end of the water inlet of the drain connector is less than the first set value, the second set value is less than the first set value, and the upper end of the water inlet of the drain connector is less than the second set value. After the drain valve 34 is closed, when the water level in the water receiving tray 2 is not lower than the first set value, the water in the drain pipe 3 can be ionized by the electrolytic water device, and when the water level in the water receiving tray 2 is lower than the first set value, the water supplementing tank 51 can supplement the water in the water receiving tray 2 in time, so that the electrolytic water oxygen generating device can operate stably; the second set value is lower than the upper end of the water inlet of the drain pipe 3, and when the water level in the electrolytic tank is higher than the second set value, the water supplementing is stopped, so that the oxygen generated by the electrolytic water can be smoothly discharged into the shell 1.

[0048] When the air conditioner runs in the heating mode, the drain valve 34 is closed, the indoor oxygen content is detected to be lower than the first preset value, the indoor hydrogen content is detected to be lower than the second preset value, and the water level in the water receiving tray 2 is not lower than the first set value, the electrolytic water oxygen generating device is powered on, the water flowing through the drain pipe 3 is ionized, so that the oxygen can enter the room and increase the indoor oxygen content, and the hydrogen is discharged to the outdoor through the drain pipe 3. When the indoor oxygen content is greater than the third preset value, the indoor hydrogen content is greater than the second preset value, the water level in the water receiving tray 2 is lower than the first set value, or the air conditioner no longer runs in the heating mode, the electrolytic water oxygen generating device is powered off and the oxygen generation is stopped. The water receiving tray 2 is supplemented by the water supplementing device, so that the air conditioner can also supplement the oxygen in the room when running in the heating mode.
