In this way, the problem of air leakage during the flow of air from the washing mechanism 40 into the dehumidifying mechanism 80 can be avoided. It will be appreciated that the aperture of the vent 93 of the air deflector 90 is equal to the aperture of the water wash outlet 14 and the desiccant inlet, thereby allowing a steady flow of air and reducing noise.

Optionally, the water mist head 41 includes a housing assembly 42, an ultrasonic atomizing plate 43, and an electrode assembly 44. The shell assembly 42 comprises a water inlet 420 and a mist outlet 421, a fluid channel 422 is arranged between the water inlet 420 and the mist outlet 421, and the humidifying outlet comprises the mist outlet 421; the ultrasonic atomizing sheet 43 is disposed in the fluid channel 422 and corresponding to the water inlet 420, for atomizing the passing water flow; the electrode assembly 44 is disposed in the fluid passage 422 between the ultrasonic atomizing plate 43 and the mist outlet 421 for positively charging the passing water mist.

Optionally, the housing assembly 42 includes a front housing 4210, a middle housing 4220, and a rear housing 4230 sequentially connected in a fluid flow direction, the front housing 4210 being provided with a water inlet 420, the rear housing 4230 being provided with a mist outlet 421; the ultrasonic atomizing sheet 43 is disposed in the fluid passage 422 between the front housing 4210 and the middle housing 4220 for atomizing the incoming water flow to form a water mist; the electrode assembly 44 is disposed in a fluid passage 422 between the center housing 4220 and the rear housing 4230 for applying an electrical charge to the passing water mist to form a charged water mist.

By adopting the water mist head 41 provided by the embodiment of the disclosure, water flows enter the fluid channel 422 of the shell assembly 42 from the water inlet 420, are atomized to form water mist when passing through the ultrasonic atomization sheet 43, are applied with electric charge to form charged water mist when passing through the electrode assembly 44, and are sprayed out from the mist outlet 421, so that on one hand, indoor air can be humidified, and on the other hand, pollutants such as particulate matters in the air can be adsorbed, and the air purification is realized.

The water flow enters the fluid channel 422 from the water inlet 420, forms water mist through the ultrasonic atomization sheet 43, forms water mist carrying positive charges through the electrode assembly 44, and is sprayed out from the mist outlet 421. The ultrasonic atomizing plate 43 can generate natural water mist by using high-frequency oscillation (the oscillation frequency is 1.7MHz or 2.4MHz, which exceeds the hearing range of human beings, and the electronic oscillation is harmless to human bodies and animals) of electrons and scattering the liquid water molecule structure through the high-frequency resonance of the ceramic atomizing plate.

The electrode assembly 44 is capable of generating an electric field and the mist is capable of carrying an electric charge as it passes through the electrode assembly 44. The charged water mist has charges on the surface of the mist drops, and can absorb suspended particulate matters (such as PM2.5, pollen, dust batting and the like) in the air, thereby realizing the air purification effect. And, by adjusting the spray amount and the electrode assembly 44 voltage, the mist droplets can be further ionized to form hydrogen ions and hydroxyl radical plasma, and virus and bacteria in the air can be killed. In addition, since formaldehyde is dissolved in water, the air entering the washing mechanism 40 is humidified by atomization, and the contact area between formaldehyde and water can be increased, so that the formaldehyde removal effect is also given.

Alternatively, the electrode assembly 44 includes a first electrode 4401 and a second electrode 4402, the first electrode 4401 being annular in shape to allow water mist to pass through an area enclosed thereby and to apply an electrical charge to the water mist; the second electrode 4402 is ring-shaped and has a larger diameter than the first electrode 4401, and is disposed adjacent to the first electrode 4401 in the fluid flow direction so that the mist passes through the area surrounded by the electrode and charges smaller than the charge amount of the first electrode 4401 are applied to the mist.

With this alternative embodiment, the mist can be subjected to an electric field while passing through either the first electrode 4401 or the second electrode 4402. As is well known, the smaller the radius of the electrode, the stronger the electric field strength is produced, and since the diameter of the second electrode 4402 is larger than the diameter of the first electrode 4401, the amount of charge applied by the water mist when passing through the first electrode 4401 is larger than the amount of charge applied by the water mist when passing through the second electrode 4402. In this way, by controlling the first electrode 4401 and the second electrode 4402 to switch the power supply, the amount of charge applied to the water mist can be adjusted. When the electric charge amount carried by the water mist is different, the air purifying effect is also different.

In some alternative embodiments, the middle housing 4220 comprises a first housing 4221 and a second housing 4222 connected, the first housing 4221 being connected to the front housing 4210 and disposed between the ultrasonic atomizing plate 43 and the first electrode 4401 for securing the first electrode 4401; the second case 4222 is connected to the rear case 4230, and is disposed between the first electrode 4401 and the second electrode 4402 for fixing the second electrode 4402.

With this alternative embodiment, the middle case 4220 includes a first case 4221 and a second case 4222, the first electrode 4401 and the second electrode 4402 are respectively located at both sides of the second case 4222, and the second case 4222 separates the first electrode 4401 and the second electrode 4402 from each other to avoid mutual influence; the first electrode 4401 and the ultrasonic atomizing plate 43 are positioned at both sides of the first housing 4221, respectively, and the interaction between the first electrode 4401 and the ultrasonic atomizing plate 43 can be avoided.

Optionally, the water washing mechanism 40 further comprises a water box 45, the water box 45 being arranged outside the first housing 10 and being in communication with the water mist head 41 for providing a water source to said water mist head 41.

Optionally, a drain port 33 is provided at the bottom of the spiral duct 30 to drain the sewage generated in the spiral duct 30. Thus, the sewage is discharged through the water discharge port 33, and the accumulation of water in the spiral duct 30 is prevented. Alternatively, the drain port 33 is connected to a water receiving tray of the indoor unit of the air conditioner through a water pipe. Thus, the sewage can be firstly discharged into the water receiving disc, converged with the condensed water in the water receiving disc and then discharged outdoors.
