Description

The utility model relates to room ventilation devices and can be used in the design of a supply ventilation valve.

The most famous supply ventilation valve is the KIV-125 valve, see information on the Internet link: http://www.eneq.ru/prod_elements/klapans/kiv.html

In Russian patents, the first mention of KIV-125 dates back to 2008, see the description of the patent RU 75717 U1, IPC F24F 13/08, publ. 08/20/2008.

The supply ventilation valve includes a ventilation pipe designed to be placed in an opening in the outer wall, an outer cover with a grille, as well as a housing in which the coarse air filter is located, a damper made of two halves, a damper gear and a rotary control.

The disadvantages of the KIV-125 valve are:

- the complexity of the design due to the use of a gear drive to drive the damper halves;

- insufficient reliability of the valve design, due to the presence of many moving parts in the design - damper halves with an axis of rotation, gears.

- inconvenience of operation due to the location of the control valve in the air duct not visible from the outside.

From the patent description DE 202007009273 U1, IPC F24F 13/08, publ. 12/18/2008, a supply ventilation valve is known, which includes an outer pipe, an outer cover with a grille, as well as an inner pipe and a housing equipped with ventilation slots and a cone-shaped locking device with sector-shaped slot-shaped holes. To regulate the intensity of air supply, it is proposed to move the housing with a conical shut-off device relative to the inner pipe.

The fresh air valve, the design of which is known from the patent description DE 202007009273 U1, is manufactured by Marley Deutschland GmbH (DE), see information on the Internet link:

https://www.marley-spb.ru/docs/klapan-Marley.pdf

The disadvantages of the fresh air valve, known from the description of the patent DE 202007009273 U1, are:

- design complexity due to the use of a cone-shaped locking device with sector-shaped slot-like holes;

- insufficient reliability of the valve design, due to the presence of many moving parts in the design;

- inconvenience of operation due to the need to move the entire body with the locking device.

From the description of the patent RU 83318 U1, IPC F24F 7/04, F04B 1/70, publ. 05/27/2009, a supply ventilation valve is known, which includes external and internal pipes, an external cover with a grille, and a housing with ventilation slots. In this case, the housing includes a coarse air filter, a damper mechanism with a four-leaf diaphragm, and a control element made in the form of a slider. The intensity of air supply is regulated by changing the position of the slider, the linear movement of which is converted into rotational movement of the diaphragm blades.

The supply ventilation valve, the design of which is known from the description of the patent RU 83318 U1, under the trade name “VENTS PS Wall Ventilator” is produced by Ventilation Systems CJSC (UA), see information on the Internet link: https://vents.ua/series /wall-vent-ps

The disadvantages of the above-mentioned fresh air ventilation valve are:

- the complexity of the design due to the use of a diaphragm with many blades;

- insufficient reliability of the valve design, due to the presence of many moving parts in the design;

- inconvenience of operation due to the location of the slider in the lower, poorly visible end part of the housing.

From the description of the patent RU 178462 U1, IPC F24F 7/00, F24F 13/08, publ. 04/04/2018, a supply ventilation valve is known, which includes an external cover with a grille, a hollow cylindrical air duct made of heat and sound insulating material, a housing with ventilation slots, an adjustment mechanism installed in the air duct and made in the form of fixed and movable cups, each of which is equipped with two sector cutouts, and a rotary control, one of the cups being mechanically connected to the rotary control.

The supply ventilation valve, the design of which is known from the description of the patent RU 178462 U1, under the trade name “Supply ventilation valve “ION”” is produced by Lynx LLC (RU), see information on the Internet link: http://pvk-ion. rf/

The disadvantages of the above valve are:

- the complexity of the design due to the implementation of the adjustment mechanism in the form of cups with cutouts;

- insufficient reliability of the valve design, due to the presence of many moving parts in the design;

- low efficiency of use of the air duct, due to the possibility of opening approximately half of the cross-section of the air duct;

- inconvenience of use due to the presence of friction in the cup/cup pairs and the control/hole in the body;

- inconvenience of operation due to the location of the control valve in the air duct not visible from the outside.

The closest analogue of the claimed utility model is the supply ventilation valve, which is produced by Domvent Production Company LLC (RU) under the trade name “Norvind Optima”, see information on the Internet links:

https://norvind-company.com/products/norvind-optima/

https://domvent-master.ru/norvind-optima/

The closest analogue includes an outer cover with a grille, a pipe, a heat and noise insulating liner, a housing made in the form of a horizontally oriented parallelepiped with rectangular ventilation slots formed in the lower wall of the housing and arranged in one row, the body contains a heat and noise insulating box, a coarse air filter and a shutter made of polymeric material in the form of a plate, with a control element formed integrally with the shutter and partially protruding from an opening in the front wall of the housing.

The disadvantages of the closest analogue are:

- inconvenience of operation due to the increased dimensions and weight of the damper;

- inconvenience of operation due to the intuitively incomprehensible trajectory of movement of the control.

The task that the utility model is aimed at achieving is to develop a supply ventilation valve that is free from the disadvantages of the closest analogue.

The technical results that the utility model is aimed at achieving are reducing the size and weight of the damper and increasing ease of use.

The above technical results are achieved in a supply ventilation valve, which includes an outer cover with a grille, a pipe, a heat and noise insulating liner, a housing made in the form of a horizontally oriented parallelepiped with rectangular ventilation slots formed in the lower wall of the housing and located in one row in the housing there is a heat and noise insulating box, a coarse air filter and a damper made of polymer material in the form of a plate, with a control element formed integrally with the damper and partially protruding from the housing through a hole in the front wall of the housing.

This technical result is achieved by the fact that the ventilation slots are made with a constant pitch L, rectangular holes with the same constant pitch L are formed in the damper, and the hole in the front wall of the housing is made of an elongated shape for longitudinal movement of the control element.

Moreover, in the best case of implementing the utility model, the area of each of the holes in the damper is slightly less than the area of the ventilation slot to ensure complete closure of the slots with small dimensions and weight of the damper.

The utility model is illustrated by the following images.

In FIG. 1 shows the supply ventilation valve, general view.

In FIG. Figure 2 shows the details of the supply ventilation valve body.

In FIG. 3 shows the details of the heat and noise insulation box.

In FIG. Figure 4 shows the damper of the fresh air ventilation valve.

L is the pitch between the slots and between the holes in the damper.

The utility model can be successfully implemented in the design of the supply ventilation valve 1, which includes (see Fig. 1 - 6) an outer cover 2 with a grille, a pipe 3, a heat and sound insulating liner 4, a housing 5 made in the form of a horizontally oriented parallelepiped with ventilation slots 6 formed in the bottom wall 7 of the housing 5 and arranged in one row, in the housing 5 there is a heat and noise insulating box 10, a coarse air filter 11 and a damper 12 made of a polymer material in the form of a plate, with a control element 14 formed integrally with damper 12 and partially protruding from hole 15 in the front wall of housing 5.

To implement the utility model, the following changes are made to the valve design.

Ventilation slots 6 are made at equal distances with a constant pitch L.

Holes 13 are formed in the damper 12 with the same constant pitch L.

The hole 15 in the front wall 8 of the housing 5 is made of an elongated shape for the longitudinal movement of the control body 14.

In this case, in the best case of implementing the utility model, the area of each of the holes 13 in the damper 12 is slightly less than the area of the ventilation slot 6 to ensure complete closure of the slots 6 with the small size and weight of the damper 12.

The proposed changes in the design of the supply ventilation valve 1 make it possible, in comparison with the closest analogue, to significantly reduce the size and weight of the damper, which helps reduce the force applied to the control element 14 to move the damper 12 and increases the ease of use of the supply ventilation valve 1.

The shape of the ventilation slots 6 and the holes 13 in the damper 12 is the same and in the simplest case can be rectangular, which does not exclude making holes of other shapes, for example, polygonal, oval, shaped, etc., which can increase the attractiveness of the appearance of the body 5 of the valve 1 supply ventilation.

The fresh air ventilation valve 1 is installed in a known manner.

A hole is made in the outer wall of the room.

A pipe 3 and a heat and sound insulating liner 4 are installed in the hole.

Thermal and noise insulating liner 4 can be installed inside pipe 3 or outside pipe 3, depending on the diameter of the wall hole and the diameter of the pipe used.

From the street side, an outer cover 2 with a grill is installed at the end of pipe 3. The rear wall 9 is removed from the housing 5 and, pressing the wall 9 against the wall so that the end of the pipe 3 enters the hole in the rear wall 9, the locations of the mounting holes for attaching the housing 5 to the wall are marked.

Drill mounting holes in the wall and install dowels in them.

Attach the rear wall 9 of the housing 5 to the wall using screws.

The housing 5 is connected to the rear wall 9 using latches located on the rear wall 9. The device is ready for operation.

The fresh air ventilation valve 1 is used in a known manner.

In the initial state (see Fig. 5), the control element 14 is in the extreme left position. In this case, the damper 12 completely closes the ventilation slots 6, and air from the street does not pass into the room. When the control element 14 moves to the right, the holes 13 in the damper 12 are located opposite the ventilation slots 6, and air from the street enters the room.

In the extreme right position of the control body 14, the ventilation slots 6 are completely open to air from the street.

Placing the control 14 on the front wall 8 of the housing 5 increases the ease of operation of the supply ventilation valve 1.

The movement of the control element 14 left/right coincides with the smooth opening/closing of the ventilation slits 6 and is intuitive to the user, which increases the ease of operation of the supply ventilation valve 1.

The operation of the damper 12 can be visually observed by the opening/closing of the ventilation slots 6, which also increases the ease of operation of the supply ventilation valve 1.

If necessary, filter 11 for coarse air purification is replaced. To gain access to the coarse air filter 11, the housing 5 is disconnected from the rear wall 9.

Conducted patent research confirms the world novelty of the utility model.

The operation of prototypes of the utility model confirmed its industrial applicability and compliance with the stated technical results.
