Chinese patent application No. 97222298.7 discloses a removable and usable condensate water air conditioner, in which the condensate water of the air conditioner is collected on a bottom plate (or in a plastic tank) and enters a sink through a water outlet nozzle, and a photoelectric tube closely monitors a lower water surface line and an upper water surface line of the sink. When the condensed water reaches the upper water line, the power supply for starting the water pump is switched on under the action of the photoelectric tube, and the water pump starts to suck the condensed water in the water tank. When water pumped by the water pump enters the main pipeline and enters the branch pipelines from the main pipeline under the action of water pressure, small holes which are uniformly distributed are arranged on the downward side of the branch pipelines, condensed water uniformly flows to be sprinkled on the surfaces of the condenser fins, and strong wind blows the condensed water into water mist to be dispersed into air under the high-speed rotation of the axial flow fan. However, the proportion of the recovered condensed water to mist is small, the condensed water is not fully utilized, and the noise is relatively high.

The air conditioner is divided into an inner machine 7 and an outer machine, and the split wall-mounted air conditioner inner machine 7 generally comprises an air suction grid, an air filter screen, an evaporator 1 and the like.
As shown in fig. 2, the top of the inner side of the tail end air outlet 8 of the inner machine 7 is provided with a sound liner 9, and a condensed water recovery tank 2 and an electrolytic tank 3 are arranged below the evaporator 1 and the tail end air outlet 8. An electric heating tube 4 for heating the condensed water is arranged in the condensed water recovery tank 2, and a water electrolysis electrode 5 for electrolyzing the condensed water is arranged in the electrolytic tank 3. The condensed water recovery tank 2 and the electrolytic tank 3 are both communicated with a water replenishing device 6.
As shown in fig. 3, a condensate water recycling tank 2 is arranged below the terminal air outlet 8 for recycling condensate water formed when the supercooled cold air blown out from the terminal air outlet 8 of the internal machine 7 meets hot air, so as to prevent the condensate water from dropping onto the indoor floor.
As shown in fig. 4, when the air conditioner collects the condensed water of the air conditioner during the cooling process and the condensed water is less than two thirds of the volume of the condensed water recovery tank 2 or the air conditioner heats, the water supplementing device 6 supplements water to the condensed water recovery tank 2 so as to open the electric heating tube 4 and generate steam through heating and evaporation. The power of the electric heating tube 4 is 1-5 kW, condensed water collected in the condensed water recovery tank 2 is heated to 100 ℃, upward flowing water vapor is generated, and the water vapor is blown into a room along with a tail end air outlet 8 of an indoor unit 7 of an air conditioner, so that the humidifying effect is achieved, and the indoor comfort level of residents is greatly improved. Compared with the traditional method of washing water in an indoor basin, the method has more practical application effects.
As shown in fig. 5, the water electrolysis electrode 5 is a titanium-based platinum-plated electrode. Oxygen generated by electrolyzing condensed water enters the room along the tail end air outlet 8 of the inner machine 7. Water is supplemented into the electrolytic tank 3 through the water supplementing device 6, direct current with certain power is input according to the requirement of oxygen production amount, then water is electrolyzed by the water electrolysis electrode 5, so that oxygen and hydrogen are respectively generated at the anode and the cathode of the direct current, and the oxygen is brought into an air conditioning room through cold air at the tail end air outlet 8, so that the effect of increasing oxygen into the room is achieved.

The helmholtz resonator comprises an open end 901 and a cavity 902, the open end 901 can be closed by a baffle, thereby making it unable to exert a sound damping effect. The sound liner 9 is mainly used for silencing low and medium frequencies, so the frequency of air outlet from the tail end outlet is controlled to be low and medium frequencies. According to different wind speeds and corresponding different frequencies, the open end 901 of the part of the Helmholtz resonator is selectively closed for different frequencies, so that the resonance frequency of the Helmholtz resonator is consistent with the frequency of the air flowing out of the tail end air outlet 8 of the inner machine 7, and the optimal noise elimination effect is realized. The cavity 902 of the helmholtz resonator may be a cuboid, a triangular prism or a cylinder, and it can be known from simulation experiments that the silencing effect of the cuboid cavity 902 is the best under the condition that the helmholtz resonator has the same volume and the same sectional area.
As shown in FIG. 7, the cavity 902 is a square with a side length of 10cm and a gap with an open end 901 of 5 cm. Without considering the wind speed, i.e. with a default mach number of 0, the noise damping effect of the square cavity 902 of the helmholtz resonator was tested separately against its number of active operations, which was 1, 4, 8, respectively. As can be seen from fig. 7, when the amount of noise is large, 8 helmholtz resonators are selected, when the amount of noise is general, one helmholtz resonator is selected, and when the amount of noise is small, one helmholtz resonator is selected.
