Description

[0001] SUPPLY VENTILATION UNIT

[0002] The invention 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 features supply ventilation devices of various designs installed in a ventilation duct in the wall of a room or building: technical solutions under Russian patents for utility models No. 80923, 66488, 178462, 222712, 220495, 204494, 210001 and inventions No. 2744623, 2194222. The common basic design elements of these devices are, as a rule, an air duct with thermal insulation inside the ventilation duct in the wall of a room or building, an external ventilation grille attached to the air duct and a head (housing) inside the room with an opening (openings) for air outlet and an adjustable damper. Depending on the device, its design may also include a filter of one or another filtration class in the head or air duct, a supply fan, an electronic control unit, and a temperature sensor. More expensive and energy-intensive devices may also include a heating element.

[0004] Some supply air vents use magnets to secure the damper (Russian Utility Model Patent No. 224215), attach and replace the dust collector (Foreign Invention Patent No. CN210373956U), and secure the filter plate to the housing (Foreign Invention Patent No. CN214148234U). In the solution for Foreign Patent No. JP2001091004A, a magnet, double-coated self-adhesive tape, a mounting screw, or a clamp can be used to secure the head to the vent.

[0005] As a result, based on a combination of essential features, the technical solution "COMPACT SUPPLY VENTILATION SYSTEM (THE DEVICE AS A WHOLE), A DEVICE FOR FORCED AIR SUPPLY AND A VENTILATION GRILLE (INDEPENDENT PARTS OF THE DEVICE)" was selected as a prototype under Russian patent for invention No. 2708105 (priority date 21.11.2018, publication date 04.12.2019). The supply ventilation system is characterized by the fact that it consists of an inlet grille, an air duct with a filter installed inside and a forced air supply device, which in turn consists of a housing made of a decorative panel and a supporting panel with a seat, a snail containing a main housing adjacent to the housing seat and a cover, a radial fan fixed inside the snail, a damper, an electronic unit, a heater, with heat-insulating material applied to the damper, and a temperature sensor installed at the outlet of the snail.

[0006] A disadvantage of the prototype is the difficulty of replacing the corrugated filter inside the air duct, since this requires disassembling and removing the entire, rather complex, forced-air supply device (including the decorative panel, the snail, the fan, the damper, the outlet grille, the electronics unit, the support panel, its mounting seat, and the heater).

[0007] The purpose of the claimed invention is to propose a supply ventilation device, the design of which allows for easy access and replacement of the filter inside the air duct, as well as to reduce the formation of frost in the area of ​​the air outlet from the head nozzle in cold weather and to provide control of the device operation using Wi-Fi.

[0016] The device can also be equipped with a class F5 filter.

[0017] The device can also be equipped with a class F6 filter.

[0018] The device can also be equipped with a class F7 filter.

[0019] The controller can also be configured to regulate the fan speed.

[0020] The device may also include a remote control. The supply air vent may also include a sealing gasket on the vent opening of the device's head.

[0021] The supply ventilation device may also contain a plastic ring that passes through the ventilation openings of the device head and the mounting panel and is placed in the air duct.

[0022] The mounting panel may also contain a heat-insulating gasket on the back side.

[0023] The wireless data transmission channel can also be configured to transmit data using Wi-Fi technology. The wireless data transmission channel can also be configured to transmit data using Bluetooth technology.

[0024] Also, the wireless data transmission channel can be configured to transmit data using WiMAX technology.

[0025] Also, the wireless data transmission channel can be configured to transmit data using UWB technology.

[0026] The claimed technical solution is illustrated by an exploded schematic image of the supply ventilation device as a whole (Figures 1, 2) and separately the head of the device (Figures 3, 4), where 1 is the head of the device, 2 is an air outlet nozzle, 3 is a ventilation hole on the back side of the head, 4 is a supply fan with a motor, 5 is an automatic adjustable insulated nozzle damper, 6 is a stepper motor of the damper, 7 is a printed circuit board, 8 is a temperature sensor, 9 are control buttons, 10 is a power supply, 11 is built-in magnets, 12 are spring contacts, 13 is a mounting panel with a ventilation hole, 14 is a heat-insulating gasket on the back side of the mounting panel, 15 is a sealing gasket, 16 is a plastic ring, 17 is an air duct with heat insulation, 18 is an external ventilation grille, 19 - socket, 20 - air outlet area from the nozzle, 21 - printed circuit board for contact pads for connecting spring contacts.

[0027] In order to achieve the technical result, the invention can be implemented in the following preferred manner with reference to exploded schematic representations of the supply ventilation device as a whole (Figures 1, 2) and the head of the device separately (Figures 3, 4). The schematic representations are of an exclusively explanatory illustrative nature; the shape, proportions of the device, composition, appearance and mutual arrangement of its elements may differ from those shown in the images, but not go beyond the scope of the formula. It should be noted that the presented example of the implementation of the supply ventilation device does not exclude other methods of implementation within the framework of the claimed formula and in no way limits the scope of legal protection specified in independent claim 1 of the formula.

[0028] Also, the terms and concepts used in the formula and description may be understood as their synonyms, for example, the head of the device 1 is also understood as the body of the device, the nozzle 2 is an opening, the damper 5 is a valve, the mounting panel 13 is a supporting panel, etc.

[0029] The proposed supply ventilation unit is installed as follows. A ventilation duct (not shown in the images) is drilled into the wall of a room or building using a manual diamond core drill. Next, the air duct (17) for the ventilation duct is insulated to prevent freezing in cold weather, and the external ventilation grille (18) is attached to it. The air duct with thermal insulation (17) and external ventilation grille (18) are then inserted into the ventilation duct. A filter (not shown in the images) is then placed in the duct. Filters can be of class G2, G4, F5, F6, or F7.

[0030] Next, mounting panel 13 is attached to the ventilation duct through heat-insulating gasket 14 such that the ventilation opening of mounting panel 13 aligns with the opening of the ventilation duct. Mounting panel 13 is designed for attaching device head 1 to it. It is made of metal and contains contact pads (not shown in the images) located on printed circuit board 21, connected to the power supply network, for connecting spring contacts 12 on printed circuit board 7 of device head 1.

[0031] Then the head of the device 1 is attached with its back side to the metal mounting panel 13 using the built-in magnets 11 in such a way that the ventilation hole 3 for the air supply of the head of the device 1 coincides with the ventilation hole of the mounting panel 13. In this case, the spring contacts 12 on the printed circuit board 7 of the head 1 are positioned and connected to the contact pads on the mounting panel 13.

[0032] The contact pads on the mounting panel are connected to the main power supply for the room or building. The supply ventilation unit is installed and ready for operation.

[0033] The supply ventilation device operates as follows. After connecting the contact pads on the mounting panel 13 to the main power supply network of the room or building using the socket 19, the current flows through the spring contacts 12 and the power supply unit 10 on the printed circuit board 7 of the head 1 to the supply fan motor 4 located inside the head 1, the stepper motor 6 of the damper 5, as well as the controller (not shown in the images), temperature sensor 8, control buttons 9 and the wireless data transmission channel (not shown in the images) located on the printed circuit board 7. The controller controls the operation of the supply fan motor 4, the stepper motor of the damper 6, and is electrically connected to the device control buttons 9, the temperature sensor 8 and the wireless data transmission channel. The wireless data transmission channel can be configured to transmit data using Wi-Fi, Bluetooth, WiMAX or UWB technologies.Upon receiving a command to turn on the device via control button 9, a remote control (not shown in the images), or a Wi-Fi, Bluetooth, WiMAX, or UWB network, the controller connects the power supply circuit to supply current to the motor of supply fan 4, which begins operating and draws outside air from air duct 17 in the ventilation duct through nozzle 2 at the top of head 1 into the room or building. The controller can be programmed to operate fan 4 at multiple speeds, which can be switched using control button 9 on the device, a remote control, or a Wi-Fi, Bluetooth, WiMAX, or UWB network. The controller also receives information from temperature sensor 8, which measures the temperature in the room or building.If the air temperature decreases, the controller can automatically reduce the speed of the fan 4, disconnect the power supply circuit to stop the current supply to the fan motor 4 to turn it off, or turn on the stepper motor 6 of the damper 5 to completely close the nozzle 2. If the air temperature increases, the controller can automatically connect the power supply circuit to supply current to the motor of the supply fan 4 to turn it on, increase the speed of the fan 4, or turn on the stepper motor 6 of the sealed damper 5 to open the nozzle 2. You can also turn on the stepper motor 4 to open / close the damper 5 using the control button 9 on the head of the device 1. In this case, the damper is made insulated 5, which acts as additional insulation for the entire head 1, which prevents condensation from forming or freezing of the device as a whole.

[0034] Air entering from outside the room or building and forced by supply fan 4 through ventilation grille 18, filter in air duct 17, ventilation opening in mounting panel 13, and end piece 3 passes through nozzle 2 located in the upper portion of end piece 1. Nozzle 2 is designed with a regular aerodynamic shape and without slats, which prevents or reduces the formation of frost in the air outlet area of ​​end piece 20 in cold weather, and the upward-directed air flow allows for more efficient mixing with warm air layers under the ceiling. The reduction in frost formation in the air outlet area of ​​end piece 20 in cold weather due to the regular aerodynamic shape of the nozzle is confirmed by practical use of a device with nozzle 2 of this shape on end piece 1.In this case, the supply ventilation device may contain a sealing gasket 15 on the ventilation opening 3 of the head of the device 1, intended for a tighter, hermetic connection of the head of the device 1 to the mounting panel 13. Also, the supply ventilation device may contain a plastic ring 16 passing through the ventilation openings of the head of the device and the mounting panel and placed in the air duct, which prevents the leakage of air passing through the air duct 17 and the ventilation openings of the head of the device 3 and the mounting panel 13 outside into the room, that is, improves the tightness of the device as a whole.

[0035] During operation of the device, the filter located inside the air duct 17, as in all other supply ventilation devices, periodically requires replacement. Unlike the prototype and other similar devices, in the presented solution, the head 1 is attached to the metal mounting plate 13 using built-in magnets 11. To replace the filter inside the air duct 17 in the ventilation duct, simply remove the head 1 from the mounting plate 13 with a slight force in one movement, gaining access to the air duct 17 and the filter inside. Disassembling the head / housing 1 of the device is not required. After replacing the filter, the head 1 can also be easily reattached to the mounting plate 13.

[0036] The ability to connect the device wirelessly to a Wi-Fi network, as well as Bluetooth, WiMAX, or UWB, allows you to control the device, turn it on or off, and adjust the fan speed 4 from anywhere using a dedicated mobile app on your smartphone.

[0037] Thus, the distinctive features of the proposed supply ventilation device allow for the stated technical result to be achieved - to ensure improvement of its operational properties due to the fact that the device's design allows for easy access and replacement of the filter inside the air duct, to reduce the formation of frost in the area of ​​the air outlet from the nozzle in cold weather, and to ensure control of the device's operation using wireless data transmission technology.

[0038] The proposed invention of a supply ventilation device is currently being produced by the applicant.
