Description

[0001] SUPPLY VENTILATION UNIT

[0002] The utility model relates to the field of air conditioning and ventilation, namely to supply ventilation devices, and can be used for ventilation of residential and non-residential premises.

[0003] The state of the art widely presents supply and supply-and-exhaust ventilation devices of various designs.

[0004] Some of these devices contain elements, namely dampers, grilles, including louvered grilles, which allow you to regulate the volume of air entering the ventilation duct or into the room, sometimes the degree of its filtration, with the ability to completely close or open (in cases with dampers and louvered grilles) access to the air supply (Russian patents for inventions No. 2194222, 2452904, utility models No. 66488, 210001, 151723, Chinese patent for invention No. CA3033832A1).

[0005] However, all these elements allow you to regulate only the volume of incoming air, but not the direction of the air flow.

[0006] The Chinese patent for invention No. CN112013489A "AIR PURIFIER" (published on December 1, 2020) provides for a special air flow regulator that directs the air flow into the device body in a vertical and diagonal direction, in an inclined position.

[0007] Chinese Patent Application No. CN113654230A "HEATING VENTILATION SYSTEM, AIR CONDITIONER, AIR INTAKE DEVICE CAPABLE OF ADJUSTING AIR DIRECTION" (published on November 16, 2021) uses an air intake device with the ability to adjust the air flow direction. However, the ability to adjust the flow direction

[0008] 1

[0009] SUBSTITUTE SHEET (RULE 26) is again intended only for air intake, and not for its release into the room.

[0010] As a result, the technical solution "SUPPLY AIR VENTILATION VALVE" under Russian patent for utility model No. 178462 (priority date 30.03.2017, publication date 04.04.2018) was selected as a prototype. This SUPPLY AIR VENTILATION VALVE is characterized by comprising an air duct made of heat- and sound-insulating material, with a housing located at one of its ends with an air flow regulator coaxially mounted on its outer side with the ability to rotate, made with a window on the side surface. Moreover, the housing is made with slots located on the sides and an air duct channel on the inner side, ensuring the ability to align it with the regulator window when the regulator is rotated to regulate the air flow.

[0011] The prototype's shortcomings include the fact that the air flow regulator, combined with the regulator windows, partitions, air duct, and slots, essentially only regulates the volume of air entering the room from the ventilation duct and closes and opens airflow into the room. This means it does not actually regulate the direction of airflow. The airflow direction is determined by the position of the slots on the sides of the housing—air is always directed along the walls, toward the heating elements.

[0012] Thus, a technical problem was identified in the lack of the ability to regulate the direction of the air flow coming from the ventilation duct into the room in technical solutions for supply and supply-and-exhaust ventilation devices.

[0014] SUBSTITUTE SHEET (RULE 26) The purpose of the claimed utility model is to propose a supply ventilation device that allows for the regulation of the direction of the air flow coming from the ventilation duct into the room.

[0016] Accordingly, the technical result of the claimed technical solution for a supply ventilation device is as follows. The design of the proposed supply ventilation device allows for the regulation of the air flow direction from the ventilation duct into the room. The claimed utility model also broadens the range of technical solutions available for supply ventilation devices.

[0018] Also, adjustable slats in the ventilation grille can be made on a rotating platform.

[0019] 3

[0020] SUBSTITUTE SHEET (RULE 26) The device body may also contain a filter.

[0021] The device's fan can also be made radial.

[0022] Also, the heating element of the device can be made in the form of a plate electric heater.

[0023] Also, a sealed damper for the ventilation opening can be made mechanical.

[0024] Also, a sealed damper for the ventilation opening can be made electric.

[0025] The claimed technical solution is illustrated by exploded schematic images of two embodiments of the supply ventilation device according to paragraphs 1, 2 of the formula (figures 1, 2), where 1 is the device body, 2 is the rear wall of the body, 3 is a ventilation opening for air intake in the rear wall, 4 is a ventilation grille for air outlet, 5 is a mounting panel, 6 is a ventilation opening of the mounting panel, 7 is a plate electric heater, 8 is a radial fan, 9 is a power cord, 10 is adjustable slats, 11 is the air flow direction, 12 is a runner for adjusting the slats, 13 is a rotating platform, 14 is the direction of rotation of the platform, 15 are fasteners.

[0028] SUBSTITUTE SHEET (RULE 26) The proposed supply ventilation device is an element of a supply ventilation system consisting of the supply ventilation device itself and a ventilation duct in the wall of the room through which air from the street enters the device and then into the room. To do this, mounting panel 5 is installed on the ventilation duct (not shown in the images) so that the ventilation opening of mounting panel 6 coincides with the opening of the ventilation duct. Next, the device itself is attached with its rear wall 2 using fasteners 15 to mounting panel 5 so that the air intake vent in rear wall 3 coincides with the ventilation opening of mounting panel 6. After this, to connect the device, power cord 9 is connected to a power outlet (not shown in the images). The device is ready for operation.

[0029] The supply ventilation device operates as follows. After connecting the device to the power supply via the power cord 9, electric current is supplied to the fan 8 and the heating element 7. Preferably, a radial (centrifugal) fan 8 serves as the fan. Preferably, a plate electric heater 7 serves as the heating element. Fan 8 begins to draw incoming air from the street into the ventilation duct (not shown in the images) through the ventilation opening of the mounting panel 6 and the ventilation opening for air intake in the rear wall 3 inside the housing 1 of the device. Between the rear wall 2 and the mounting panel 5 there is a sealed damper (not shown in the images), which closes and opens the ventilation opening in the rear wall 3 to allow air to enter the device and then into the room. The sealed damper can be either mechanical or electrical.The air passes upwards inside the housing 1 through the plate electric heater 7, is heated and then exits.

[0030] 5

[0031] SUBSTITUTE SHEET (RULE 26) room through the air outlet ventilation grille 4. The air flow direction is illustrated in the images by arrows 11. An air purification filter (not shown in the images) can be preferably installed inside the device housing 1 under the ventilation grille 4. This filter can be, for example, a HEPA filter or a carbon filter. The filter can also be installed inside the ventilation duct.

[0032] A distinctive feature of the device is that the ventilation grille 4 contains adjustable slats 10, with the help of which it is possible to regulate the direction 11 of the air flow discharged from the device. The regulation of the direction 11 of the discharged air flow is carried out by the user using the runner 12. Figure 1 shows a ventilation grille 4 with adjustable slats 10, through which the direction of the air flow to the right and left is regulated by moving the runner 12, respectively, to the right and left. Figure 2 shows a ventilation grille 4, where the slats 10 are located on a rotating platform 13. Platform 13 rotates around its longitudinal axis in directions 14. As a result, in this case, the direction 11 of the discharged air flow is regulated not only by the runner 12 to the right and left, but also by turning the platform 13 back and forth (from wall to wall).

[0033] Thus, the stated technical result of the device’s operation is achieved – it provides the ability to regulate the direction of the air flow coming from the ventilation duct into the room.

[0034] The proposed utility model of a supply ventilation device is currently being prepared by the applicant for serial production.
