The declared technical result is achieved by a static pressure chamber for the ventilation grille, made in the form of an elongated body in the shape of a prism, one base of which is made blank, and the second is made with a built-in adapter for connecting to an air duct, while one of the faces of the elongated body is made with an opening for the ventilation a grille installed in this opening flush with the body by means of substitution elements with magnetic fasteners and corresponding magnetic fasteners, ensuring the formation of a gap between the ventilation grille and the edges of the opening of the static pressure chamber body.

In particular embodiments of the utility model, the elongated body of the static pressure chamber for the ventilation grille is made in the shape of a rectangular parallelepiped.

Or the elongated housing of the plenum chamber for the ventilation grille is made in the shape of a hexagonal prism.

Substitution elements can be made either Y-shaped or L-shaped.

The static pressure chamber for the ventilation grille is used as a transition from a round, square or rectangular air duct to the ventilation grille and is designed to reduce the pressure drop from the ventilation duct to the grille, resulting in a reduction in noise by balancing the air speed. The ventilation grille is installed in the static pressure chamber.

The plenum for the ventilation grille is connected to the duct by means of a built-in adapter in one of the bases of the plenum housing for connection to the duct. In a particular embodiment, the adapter is a nipple.

The body of the static pressure chamber is made in the form of an elongated body in the shape of a prism, the bases of which are attached to the body in any available way, for example, by screwing, joining, riveting, welding, soldering, crimping, flaring, gluing, stitching or any other suitable method known from the prior art. .

The shape of the elongated body can be any; the preferred options are a hexagonal prism with a base in the form of a regular hexagon, or a rectangular parallelepiped with a base in the form of a square.

The support element or elements are fixed inside the housing or on the inside of the ventilation grille facing the inside of the housing. The stand element can have any geometric shape. On the stand element there is a magnetic clamp, made in the form of a magnet for fixing the housing and the ventilation grille into a single structure.

The ventilation grille has an upper flat part and side edges perpendicular to it, forming a box-shaped shape. The opposite edges can be additionally equipped with protruding bent tongues. The ventilation grille is connected to the elongated body. Fixation of the elongated body and ventilation grille is carried out using magnetic latches located on the stand elements.

Structurally, the ventilation grille of the claimed utility model has a size smaller than the internal size of the opening of the prism face. And the ventilation grille is placed inside the housing opening in such a way that a gap is formed between the installed ventilation grille and the edges of the opening, which is necessary for the passage of air.

The material for making the static pressure chamber for the ventilation grill can be any suitable material, for example, dense plastic or metal, but the preferred option is to make it from metal.

Implementation of a utility model

Figures 1-3 show a static pressure chamber for the ventilation system, made in the form of an elongated housing 1; in a particular case, the housing is made in the form of a rectangular parallelepiped with one face, in which an opening 2 is formed for the ventilation grille, in which the ventilation grille 3 is installed , one of the bases of the prism 4 is made blind, the second base 5 is made with an adapter 6 (nipple). The ventilation grille 3, with the help of magnetic clamps 7, is placed in the opening 2 of the face on two stand elements 8, mounted on the opposite face of the prism 9 inside the housing 1. The ventilation grille 3 forms a gap 10 along the perimeter between it and the edges of the opening 2 for the ventilation grille.

Uniformly directed air flow is ensured by the presence of a uniform air gap between the ventilation grille and the edges of the housing opening, thanks to the precise positioning of the ventilation grille using magnetic clamps on the substitution elements and corresponding magnetic clamps, which in turn simplifies the installation/dismantling of the structure and eliminates the possibility of incorrect installation of elements products.

The elongated body of the static pressure chamber for the ventilation grille can be made in the form of a hexagonal prism, on one of the faces of which there is an opening for the ventilation grille 2, inside which the ventilation grille 3 is installed. One of the bases of the prism 4 is made blind, the second base 5 is made with an adapter 6 (nipple). The ventilation grille 3, with the help of magnetic clamps 7, is placed in the opening of the face 2 on two Y-shaped support elements 8, mounted on the opposite face of the prism 9 inside the housing 1. The ventilation grille 3 forms a gap 10 along the perimeter between it and the edges of the opening 2 for the ventilation grille .

The stand elements can be placed opposite each other on opposite sides of the housing, closer to its ends. A magnetic clamp 7 is attached to the outer side of the support elements, respectively, for fixation with a corresponding magnetic clamp on the ventilation grille. Additionally, the stand elements contain a slot 11 for fixing an additionally made protruding tongue of the outer insert (not shown in the photo).

The device is manufactured by bending or casting a body of a given shape; depending on the device, one or two edges of the body are made open. After installing the housing in the ventilation system, the external insert is attached to the housing using magnetic clamps on the stand elements, which, depending on the device, are located on the housing or external insert.

Thus, the claimed utility model, without limiting the stated volume, consists in creating a device that simultaneously performs the functions of a static pressure chamber and a ventilation grille, while the grille is already built into the static pressure chamber, which expands the functionality of the device, simplifies the design and installation, and also improves the performance of the device and increases its service life.
