Abstract
The invention relates to electrical engineering, more specifically to air humidifiers for creating an artificial microclimate and can be used to increase humidity in any rooms or offices. The humidifier solves a technical problem of increasing an evaporation surface of an evaporative filter. The forced uniform distribution of air flow on the surface of the evaporative filter and a free passage of air through said filter leads to an increase in air exchange inside a box and increases a rate of separation of water molecules from the surface of the evaporative filter, which leads to increased air humidifying efficiency in the room and to increased humidifier performance.

As the air flow created by the fan 7 intensively blows away water io molecules from the surface of the evaporative filter 5 through the diffuser 6, the evaporative filter 5 absorbs water from the water tank 4, as a result of which the water level in said water tank gradually decreases. Since the water tank 4 is made of transparent plastic, the float water level gauges 15 are visible through the windows 16. The water level is controlled.

The effect of the warm air created by the radiator on the evaporative filter 5 allows for an increase in the rate of evaporation of moisture from its surface, with the box 1 and the fan 7 being compact enough, for a reduction of energy consumption and noise level, in comparison with other known air humidifiers operating according to the same scheme but without using thermal io energy generated by a radiator or other household air heater. It also allows for increased room humidification efficiency due to the uniform distribution of humid air together with convection currents created by the radiator.
The use of air heated by a radiator for forced blowing of evaporative filters makes it possible to use less efficient fans in comparison with known humidifiers.
The use of the heated air for forced blowing of the evaporative filters 5 by the fan 7 allows for an even distribution of the air humidified by the device throughout the room, since the warm moist air coming out of the slots 2 in the front of the box 1 participates in the natural convection currents inside the room created by the radiator.
The air flow from the fan is directed forward, that is, the air is supplied from the radiator side, which allows the evaporative filter to be blown with warm air heated from the radiator, which also contributes to an increase in the rate of evaporation of moisture from the evaporative filter. In addition, the location of the air humidifier on the radiator with the fan on increases the rate of passage of air masses through the heating radiator, which also leads to an increase in heat transfer from the radiator and acceleration of natural convection in the room.
The air humidifier in accordance with the claimed invention has increased evaporation surface, due to the free passage of air through the Date recue / Date received 2021-12-09
The effect of the warm air created by the radiator on the evaporative filter 5 allows for an increase in the rate of evaporation of moisture from its surface, with the box 1 and the fan 7 being compact enough, for a reduction of energy consumption and noise level, in comparison with other known air humidifiers operating according to the same scheme but without using thermal io energy generated by a radiator or other household air heater. It also allows for increased room humidification efficiency due to the uniform distribution of humid air together with convection currents created by the radiator.

9 evaporative filter and slots of the body, allows for an increase in the rate of air passage through the evaporative filter, and this leads to an increase in the rate of separation of water molecules from the surface of the evaporative filter, thereby increasing the efficiency of air humidification in the room. The air humidifier has a small size and low energy consumption.
