[0018] Brief description of the drawings:

[0019] Fig. 1 shows a general view of an air humidifier with four compartments and four fans.

[0020] Fig. 2 shows a general view of an air humidification device with two compartments and two air ducts connected to one fan.

[0021] The figure shows: 1 - housing, 2 - partition, 3 - steam line, 4 - air line, 5 - water level sensor, 6 - ultraviolet lamp, 7 - ultrasonic steam generator, 8 - water presence sensor, 9 - inlet pipe, 10 - mechanical valve, 11 - device for supplying disinfectant and / or aromatic agent, 12 - drainage tube, 13 - fan.

[0022] Embodiment of the invention. The air humidifier consists of a sealed housing 1 with a tank-shaped lid. Housing 1 is secured to a bracket for mounting the device to a wall. Housing 1 of the device is divided into at least two compartments by a partition 2. Partition 2 is located at a distance from the bottom of housing 1, forming a common water volume for each compartment, and is attached to the side walls of housing 1 along the height of partition 2, and to the lid along the width of partition 2 via a seal.

[0023] An ultrasonic steam generator 7 connected to a power source is installed in each compartment. The first ultrasonic steam generator 7 is located in the first compartment, and the second ultrasonic steam generator 7 is located in the second compartment. At least two steam pipes 3 are installed in the cover, as well as at least two air pipes 4 connected to at least one fan 13 with a removable air filter. The fan 13 is designed to pump air into the housing 1 of the device through a removable air filter. At the same time, the first air pipe 4 and the first steam pipe 3 are installed in the cover above the first compartment, and the second air pipe 4 and the second steam pipe 3 are installed in the cover above the second compartment.

[0024] The steam pipes 3 have a constant slope towards the sealed housing 1 for draining the water condensate back into the sealed housing 1. In this case, the air humidifying device has at least one control unit configured with the possibility of wireless connection to one humidity sensor, as well as with the possibility of controlling the ultrasonic steam generator 7, the fan 13, the drainage pump, the protection system, as well as the automatic cleaning and disinfection system of water and air.

[0025] In other embodiments, the control unit is configured to wirelessly connect to at least two humidity sensors.

[0026] The presented implementation options for the technical solution with different control unit designs allow for achieving the technical result of increasing the rate of humidification and air disinfection in several rooms simultaneously.

[0027] A wired connection of at least one control unit to one or two humidity sensors is also possible. Each ultrasonic generator 7 is equipped with water presence sensors 8, which are designed to shut off the ultrasonic steam generator 7 in the event of a low or absent water level in the tank. An inlet pipe 9 for supplying water to the device housing 1 is located on the side of the tank or in the lid. The inlet pipe 9 is configured to be connected to a water filter for purifying the water entering the device housing 1. A mechanical valve 10 for filling the tank with water is connected to the inlet pipe 9. This valve mechanically shuts off the water supply when the required volume is reached, and / or an electric water supply valve.

[0028] The air humidifier is equipped with a protection system and an automatic water and air purification and disinfection system. This system includes a water level sensor 5 and a water presence sensor 8, while the automatic water and air purification and disinfection system includes a disinfectant and / or aromatic agent supply device 11 and an ultraviolet lamp 6.

[0029] In other embodiments of the claimed invention, the protection system comprises a water level sensor and / or a water presence sensor and / or a water overflow sensor and / or a sound and information alert sensor, and the automatic water and air cleaning and disinfection system comprises an ultraviolet lamp and / or a device for supplying a disinfectant and / or an aromatic agent.

[0030] The presented implementation options for the technical solution, with various variants of the leak, overflow, and lack of water protection system and the automatic water and air purification and disinfection system, allow for the technical result to be achieved, as it increases the rate of air humidification and disinfection in several rooms simultaneously.

[0031] A drain tube 12 with a beveled end is installed in the device cover, capable of being connected to a drain pump for draining wastewater from the device housing 1 into the sewer system. The drain tube 12 is installed vertically with its beveled end reaching the bottom of the device housing 1 inside a guide pipe for precise guidance and fixation of the drain tube 12 within the device. A second additional drain tube (not shown in the figures) is also provided in the device cover, capable of being connected to a water cooler. Water passes through the water cooler and returns back through the water supply tube to the device housing 1 to generate cooled steam using ultrasonic steam generator 7. A water overflow sensor is installed at a distance from the bottom of the device housing 1, located at the maximum possible filling level of the tank.

[0032] An ultraviolet lamp 6 is installed inside the tank at the water level or on the inside of cover 2 to disinfect the water and air in the tank. Cover 2 also houses a disinfectant and / or aromatic agent dispenser 11, which can be connected to a disinfectant pump for cleaning and disinfecting the water and air entering the rooms. The humidifier also includes an audible and informational alarm in the event of a leak.

[0033] The air humidifier is used as follows.

[0034] The air humidifier increases the rate of humidification and air disinfection in several rooms simultaneously, as well as the ability to separately control the humidity level in each room.

[0035] Ultrasonic Steam Generator 7, with minimal operating noise, is designed to generate water vapor by transmitting ultra-high-frequency sound waves to a membrane that continuously vibrates. This causes water molecules on the membrane to bounce and escape above the surface layer of water, thereby producing unheated water vapor.

[0036] Steam pipes 3 are used to transport steam to the required room. Steam pipes 3 are mounted in the device lid above the corresponding compartment at an angle of approximately 1-5°, tilted toward the sealed housing of the air humidifier. This ensures that any condensed water formed during steam transport flows back into housing 1 along with the water. The air humidifier is mounted on a wall using a bracket with the ability to quickly detach the tank from the lid for easy servicing. Steam pipes 3 are then routed to the rooms requiring humidification. Steam pipes 3 are installed with outlets in the wall, connected to the supply ventilation system, or installed in the walls and / or ceiling, or along the walls and / or ceiling using a mounting system. Next, the water supply pipe is connected to the inlet pipe 9 through a water filter.A drainage tube 12 is installed in the lid and connected to a drainage pump, as well as a disinfectant supply device 11, connected to the disinfectant supply pump. Power sources are then connected. The air humidifier can be controlled via a user app and connected to a smart home system, as well as the Alice and Marusya systems.

[0037] In automatic mode, if the humidity sensor in the first and / or second room reaches a preset maximum humidity level in the room, it sends a signal to at least one control unit of the device, which in turn sends a signal to the first and / or second ultrasonic steam generator 7, respectively, to turn it off and stop supplying steam to the given room. If the humidity level in the first and / or second room drops to a preset minimum value, a signal is sent to at least one control unit of the device, which in turn sends a signal to the first and / or second ultrasonic steam generator 7, respectively, to turn it on and supply steam to the given room. If at least one ultrasonic steam generator 7 is on, at least one control unit sends a signal to at least one fan 13 to turn it on.

[0038] The water overflow sensor prevents water from overflowing in the tank if mechanical valve 10 or the electric water inlet valve fails. If the water level in the box rises and reaches the water overflow sensor, the contacts close, powering the electric shut-off water inlet valve and sending a signal to the audible and informational alarm sensor. Water level sensor 5 operates on the same principle, automatically shutting off water supply to housing 1 when the water level in the tank reaches the sensor level (i.e., the maximum permissible water level in the tank). This signal is sent to the electric shut-off water inlet valve and the audible and informational alarm sensor, and it also maintains the set water level. Examples of application of the claimed invention.

[0039] The air humidifier is used to create a comfortable microclimate in hotel rooms. A comfortable microclimate in a hotel room is defined by a temperature of 18-20°C and humidity of 35-45%. The humidifier itself is mounted on a special bracket, suspended above the floor, in a utility room with access to the sewer system and water supply. The device is designed to increase the rate of humidification and disinfection in five rooms located on a single floor. The device's housing is equipped with four partitions dividing the unit into five compartments, five steam pipes, five ultrasonic steam generators, and five air ducts with five fans and removable air filters. A single control unit is also included, allowing wireless connection to five humidity sensors in the hotel rooms.

[0040] Steam lines were installed in each room, mounted within the ceiling on a mounting system with the steam line's exhaust outlet flush with the wall. Humidity sensors with wireless connections to the unit's control unit were installed on the wall in each of the five rooms. The unit's inlet pipe has an electric water supply valve. For safety, the unit is equipped with a water presence sensor, an overflow sensor, a water level sensor, and an audible and informational alarm for transmitting data to a mobile app. To purify and disinfect water and air in the hotel rooms, the unit is equipped with an ultraviolet lamp on the inside of the lid and a dispenser for disinfectant and fragrance, programmed to dispense a combined disinfectant every four hours at a rate of 4 ml per liter of water.

[0041] An air humidifier is also used to humidify and disinfect the air in beauty salon treatment rooms. Regulating humidity levels in beauty salons is important to maintain comfortable conditions for clients with different skin types and concerns. High humidity leads to excessive sweating and sebum production in both oily and normal skin types. Low humidity, on the other hand, causes dry skin, especially in dry and combination skin types, and mucous membranes, as well as eye and respiratory irritation. Maintaining optimal humidity levels in beauty salons helps maintain healthy skin, tailored to each client's individual needs, and provides a comfortable work environment for the specialist. A two-compartment air humidifier was mounted on a bracket on the wall in the salon's hallway, with steam lines leading to two treatment rooms. The steam lines were connected to the treatment room's supply ventilation system.

[0042] Humidity sensors with wireless connections to the first and second control units of the device were installed on the wall in the first and second cosmetology rooms, respectively. The device's inlet pipe has a mechanical water supply valve. To pump air into the device's lid, two air ducts were installed, connected to a single fan with a removable air filter, above the first and second compartments (See Fig. 2). For protection, the device was equipped with a water presence sensor and an overflow sensor. To purify and disinfect water and air in the room, a disinfectant dispenser (e.g., a guanidine-based disinfectant) was installed in the device's lid, programmed to dispense the disinfectant every 2 hours at a rate of 2 ml per 1 liter of water.

[0043] In addition to the above, an air humidifier is used in the laboratory for studying various plant species. To create optimal conditions for plant growth and development, three rooms were constructed in the laboratory: one for tropical rainforest plants with a humidity level of 77-88%, one for temperate latitude plants with a humidity level of 40-60%, and one for desert and dry steppe plants with a humidity level of 30-45%.

[0044] The humidifier was mounted on the wall with a bracket in the mechanical room. The unit's body is divided into three compartments by partitions, located at a distance from the bottom of the unit and attached to the side walls of the unit at the height of the partitions, and to the lid at the width of the partitions via a rubber seal. Each compartment contains one ultrasonic steam generator. Three openings for three steam pipes were made in the unit's lid, and three air ducts with three fans and removable filters were installed for each compartment. Each steam pipe was routed to the designated plant room. The outlets were installed in the wall, protruding into the rooms at an angle. A humidity sensor with a wireless connection to a single, shared control unit was mounted on the wall in each of the three rooms. The unit's inlet pipe has an electric water supply valve.Timely air disinfection helps reduce the growth and development of fungal and bacterial plant diseases, especially in rooms with high humidity levels for tropical rainforest plants. For protection, the device is equipped with a water level sensor, a water presence sensor, an overflow sensor, and an audible and informational alarm. To purify and disinfect water and air, the device includes an ultraviolet lamp installed on the side of the tank at water level and an aromatherapy dispenser in the lid, programmed to dispense aromatherapy every 6 hours at a rate of 4 ml per 1 liter of water.

[0045] The technical result of the invention consists in increasing the speed of humidification and disinfection of air in several rooms simultaneously.

[0046] The said technical result is achieved due to the fact that the air humidifying device comprises a sealed housing with a lid, divided into at least two compartments by a partition, wherein the partition is located at a distance from the bottom of the housing and is connected to the side walls of the housing along the height of the partition, and to the lid along the width of the partition through a seal, at least one control unit, wherein inside the housing there are at least two ultrasonic steam generators with a protection system, as well as with a system for automatic cleaning and disinfection of water and air, at the same time the first ultrasonic steam generator is located in the first compartment, and the second ultrasonic steam generator is located in the second compartment, on the side wall of the housing or in the lid there is an inlet pipe with an electric water supply valve or a mechanical water supply valve, at the same time the following are installed in the lid:

[0047] - at least two air ducts connected to at least one fan with a removable air filter;

[0048] - at least two steam pipes, wherein the steam pipes have a constant slope towards the housing to drain water condensate back into the sealed housing;

[0049] - a drainage tube adapted to be connected to a drainage pump; at the same time, the first air duct and the first steam duct are installed in the cover above the first compartment, and the second air duct and the second steam duct are installed in the cover above the second compartment.

[0050] Based on this, we conducted a comparative analysis of the claimed device with a similar device, whose housing has a single compartment with two steam ducts, one air duct with a fan, and one ultrasonic steam generator. We measured the time required to simultaneously increase the humidity level in several rooms to 40% under identical operating conditions for the humidifiers. The results are presented in Table 1.

[0051] Table 1

[0052] Comparative analysis of the claimed invention with its analogue

[0053] The obtained results demonstrate that the claimed air humidifier device provides a 1.4-fold increase in the rate of air humidification and disinfection in multiple rooms simultaneously compared to similar devices. The invention also disinfects water and air by incorporating a disinfection system in the form of an ultraviolet lamp and / or a device for dispensing a disinfectant and / or aromatic agent. Increased air humidification in multiple rooms is possible by dividing the device's housing into compartments with partitions, installing a first ultrasonic steam generator, a first steam line, and a first air duct in the first compartment; a second ultrasonic steam generator, a second steam line, and a second air duct in the second compartment; and so on, up to the calculated number of rooms required for humidification.The device also includes at least one fan with a removable filter for forcing air into the device's housing through connected air ducts, which distributes steam to the appropriate rooms. Thus, the claimed invention increases the rate of humidification and disinfection of air in several rooms simultaneously by an average of 45%.
