The inventive device contains placed in the housing 1 with the supporting elements 9, the water tank 2 with the conversion element 3, which is a body with through pores, in contact with water in the water tank 2 and rotating under the action of an electric drive with the formation of water dust in the air chamber 4, formed by the space between the transforming element and the fan 6, where the air flow and the stream of mist are circulated, and the cleaned and moistened air leaves through the outlets 5 placed on the side surfaces of the housing 1. Fan 6 provides for forced movement of air flow through the air inlet 7, located in the upper part of housing 1. On the outer surface of the housing is a control panel 8 with controls (not shown). In the cavity of the housing 1 is placed a vertical tube 10 for filling the water through the inlet of the tube 10, having a conical expansion in the area of the inlet. The tube 10 is provided with through side holes 11 for the flow of water into the water tank 2. Inside the vertical tube 10 is placed the upper part of the float valve 12, which has essentially a cylindrical shaped surface, in the lower part of the float valve 12 has an annular thickening 13 that extends beyond the boundaries of the lower end of the vertical tube 10. Stoppers 14 are installed in the vertical tube 10, limiting the float valve 12 up. Inside the cavity of the housing 1 is placed a control unit 15 containing a printed circuit board with a programmable microcontroller, radio elements (not shown). The electrical connection is provided by electrical wires from the power source 16.

The inventive device in the normal mode works as follows.

To start the device, it is necessary to turn it on by setting the switching mode by interacting with the controls on the control panel 8. Water is poured into the vertical tube 10 from above. The lower end of the float valve 12 and the bottom of the water tank 2 are installed with a gap. The float valve 12 is fixed by the stoppers 14, which do not allow it to fall out of the tube 10 when it is moved. When water is poured, due to the rising water level in the water tank 2, the float valve 12 rises up through the tube 10. The upper part of the float valve 12 reaches the maximum height in the tube 10 when the maximum volume held by the water tank 2 is reached. , closing the through side holes 11, which are placed below the level of the maximum height to which the float valve 12 can rise. The excess water, which does not hold the water tank 2, remains above the surface lyvshego up float valve 12 being indicative of maximum filling of the container 2 for water.

When water from the tank 2 is evaporated, its level decreases, and the float valve 12 slowly descends down the tube 10, opening access to the through side openings 11 through which water flows into the water tank 2, thereby ensuring automatic replenishment of the water level in the tank 2 and uninterrupted operation of the device. If the consumer does not repeat the water inlet, the float valve 12 is lowered to its original state and hooks onto the stoppers 14, which limit the minimum stroke level of the float valve 12.

 The conversion element 3, which is in contact with water poured into the water tank 2, breaks it up into tiny particles, forming water spray, which rises into the air chamber 4. The fan 6 forces air from the room through the air intake port 7, where there is a mixture of the input air flow and mist. As a result of the rotation of the transforming element 3 and the joint movement of the flows in the air chamber 4, the air cleared of dust and enriched with the water phase is blown into the room through the air outlets 5. The dust particles are deposited on the bottom of the water tank 2. Periodically, the device is cleaned of contamination by removing the water tank 2.

Thus, the use of the claimed device provides simultaneous humidification and air washing, expanding the range of compact stand-alone devices designed to be placed on horizontal surfaces and having the ability to indicate the water level without disassembling the device and uninterrupted operation.
