On the other hand, the problem of automatic indoor ventilation is very relevant for such systems, especially for tall buildings, as the opening of the window is against the requirements of safety equipment and it is desirable that these windows do not open and thus ventilate the indoor spaces.

A device for automatic window cleaning and ventilation, comprising a window cleaning element (5), a window cleaning element slider (3a) made in the form of toothed belts, a body made of a frame, mounted on a window frame (30) and a frame constructed as such: The section consists of two sections divided horizontally by a partition above the window surface (33 and 32), where the first section (32) is directed to the opposite side of the facade, while the second (33) is to the side of the façade attached to the bracket (10a). In addition, the engine shaft is connected to the pulley (2a) along the engine. On the other side of the second section, the first axis of rotational cylindrical shape (11a) is placed in two bearings (7th and 7d). The switch for moving the window cleaning element first and second mechanisms (8a and 8b) is located in the same section. The right and left sides of the frame are constructed in such a way that grooves are formed on their inner ridges, and the lower side of the frame is constructed in such a way that the bearings (7a, 7b, and 7c) are inserted in the bearings (7a, 7b, and 7c). The third (2c) and fourth axles (2d), the first axle of the engine shaft (2a) and the third axle (2g) of the second axle, as well as the second axle (22b) of the first axle and the fourth axle (2d) of the second axle, respectively, are placed next to each other. Fasteners (6a) are attached to the toothed belts (3a and 3b) where the connecting elements are mounted on brackets (6b) in which the ends of the window cleaning element (5) made in the form of a metal stem are attached so that the cleaning element is in a horizontal position with the window surface and the entire length of the window cleaning element (5). The rubber is attached to the surface of the window. However, the toothed belt (3b) is fastened by a plastic plate element (9) on the first axle (11a) and second axle (11b) pulley wheels (2b and 2d). The window cleaning element moves up and down (8b) to bring the second mechanism into action, and the first mechanism for moving up and down the window cleaning element (8a) is made directly by the action of the cleaning element (5). Each switching mechanism being a relay, the second (8b) of which provides engine (1) shutdown and reversing when in contact with the corresponding element. It also contains an additional washing solution valve (13) equipped with pipes (14a and 14b), a ventilation box (12), an ozonator (18), filters (20 and 29) speakers (25) and a control board (26). The Hose connecting the washing solution valve to the pump (13), the connecting pipe to the water valve pump (14b) and the ventilation box (12) are placed in the first section of the housing (32). The wash solution valve is also connected (separately from the washing solution tank pump) to the outlet hose (14a).

In addition, the system elements are located in the first (32) and second sections (33) of the device frame. The ventilation box (12), located in the first section, also acts as a partition (34) between the first and second sections. It is divided into four sections. On the front and back of the box there are ventilation holes. Ventilation holes are equipped with lids (21a and 21b), which can move through the belt (22a), and thus are equipped with the ability to close and open the air flow from the movement holes. As a result of opening and closing the ventilation openings, the inflow of air flow into the ventilation box is stopped. The belt (22a) is connected to the electric motor by four pulleys (23e, 23v, 23g and 23h). In the first section of the ventilation box (12) there are also 1 to 3 fans (15a) for air flow, and in front of the 1 to 3 fans there is a filter (29), which is wound on one wheel (16), The winding filter is turned on the second wheel where each wheel is equipped with an engine (17). In the same section there is an ozonator (18) and in front of it there is a moving charcoal filter (20). The carbon filter (20) is attached to the toothed belt (22b). The belt is attached to the pulleys (23a, 23b, 23g and 23d). The pulley (23g) is attached to the motor (24a), which allows the carbon filter (20) to move. The carbon filter moves or is taken when the ozonator is switched on with the appropriate software command and the interior of the building is ° zonated. When the ozonator is switched off, the coal filter returns to its original state or closes. When the coal filter is closed, the ozonator is switched on with the appropriate software command. The air is ° zonated, after which it passes through a closed charcoal filter, which removes 03. As a result, we receive oxygen-enriched air inside the building. Also placed in the second section are the control unit (26), the C02 sensor (27), the temperature and humidity sensors (28). The third section houses the “speaker” (25). In the fourth section there are 1 to 3 fans (15), which allows the interior of the building access to the air outlet from the space. The ventilation box in turn is connected to the top of the frame (31) and equipped with ventilation openings.

Additionally, the device contains four pulleys (2e, 2v, 2z and 2h) at the top of the frame, connected to the electric motor (1) for additional tension of the belt (3a and 3b).

Thus, the technical result of the proposed invention is to simplify the construction of the device, making it possible to clean the glass surface without human resources, which is also financially profitable. In this case, the glass cleaning, which is carried out by a climber and costs from 4 to 18 dollars per square meter depending on the complexity of the window, is reduced to 1 dollar per square meter through the proposed invention.

The invention is explained by five figures:

FIG. 1-Schematic representation of the first section is shown.

FIG. 2-A schematic representation of the second section and frame is shown.

FIG. 3-The layout diagram of the device window frame is shown.

FIG. 4-A schematic drawing of 4 sections placed in the ventilation box is shown.

FIG. 5-The schematic image page of the second section and frame is shown.

After giving the appropriate order through the application, the software power unit block (26) is switched on. From the pump located in a separate tank, the washing solution is supplied to the aluminium perforated pipe (4) through the washing solution valve (13) through which said solution is supplied to the surface.

At the same time the electric motor (1) is switched on, the first pulley (2a) attached to it starts moving. This causes the first toothed belt to move in 3a. The movement is transmitted to the second axle (11a) and, accordingly, the second toothed belt (6b) moves the window cleaning element (5) from a top to bottom direction. At this point, the element (9) attached to the second toothed belt (6b) moves upwards and when it touches the second gear (8b) of the window cleaning element (5) located on the first axle, the window cleaning element (5) stops.

The time is calculated in such a way that at this point the cleaning element (5) is present on the lower side of the cleaning surface. At the same time, the cleaning element (5) starts moving from the bottom to the top through the reversing electric motor (1). When it reaches the top of the cleaning surface, it touches the first mechanism for moving the window cleaning element up and down (8a), causing the device to work. The second button of the application turns on 1 to 3 fans of the ventilation (15a and 15b) connected to the ventilation slot (31), and the building is ventilated.

The ventilation box works as follows: After giving the appropriate order through the application, the ventilation lids (21a and 21b) located in the first and third sections of the ventilation box (12) are activated, which move through the electric motor (24a), pulleys (23e, 23v, 23g, 23h) and belt (22a).

1 to 3 fans (15a and 15b) located in the first and third sections are switched on in parallel, with 1 to 3 fans introducing air from the first section (15a). From the first section enters the air through the HEPA filter (29). The ozonated air enters the indoor space through the coal filter (20) and we receive oxygen-enriched air (ionization). At the same time, in the third section 1 to 3 air vents (15b) are involved. After giving the appropriate order through the application, the ventilation lids located in the first and third sections of the ventilation box (12) are turned on (21a and 21b), which are driven by an electric motor (24a), pulleys (23e, 23v, 23z, 23h) and a belt (22a). 1 to 3 fans (15a and 15b) located in the third section are turned on in parallel. 1 to 3 fans introduce air from the first section (15a and 15b). The turbine introducing air from the first section (15a) introduces air through the HEPA filter (29) into the deaerator space (19). The carbon filter (20) located in front of the deaerator space moves to the left of the first section through the engine (24a), belt (22b), and pulleys (23a, 23b, 23c, 23d)., and ozonated air enters the interior of the building. At the same time, 1 to 3 fans (15b) of the third section air outlet are switched on as well as 1 to 3 fans (15a) located in the first section. The turbine (15a) located in the first section is constructed in such a way that the construction is marked on the sides with sockets suitable for toothed wheels. The wheels are attached to said socket (16) then rewind, which increases the filter length by 7-8 times, at the expense of the length of the HEPA filter (29) attached to the wheels.

A HEPA filter (self-priming filter) is compactly designed to extend the life of the air filter. The next button on the application turns on the speaker (25) in the fourth section and emits the sound from any device connected to it. In addition, all the functions of this window are managed through the control block (26) located in the second section. In addition, C02 (27), temperature and humidity sensors (28) are connected to the control unit (26) located in the second section. Consequently, all the information from the control block is transmitted to the server, and this window is managed automatically through the application. Clicking the next button in the application activates the fully automated window with the same functions as mentioned above.
