RU182732U1 - VENTILATION GRILLE FOR SYSTEM WITH NATURAL AND FORCED VENTILATION - Google Patents

Abstract

The utility model relates to the field of civil engineering, namely to ventilation grilles in systems with a forced exhaust device.

In the process of cooking, various combustion products are released that can adversely affect human health.

Being in a room with a high content of air of combustion products, evaporation and carcinogens can adversely affect well-being and performance, which leads to rapid fatigue and reduced concentration.

The technical result, which the utility model aims to achieve, is to improve the microclimate and sanitary conditions for people in the room by eliminating the effect of backdraft in the room when the exhaust device is turned on, due to the closure of the opening for natural ventilation and preventing the injection of air into the room.

The technical result is achieved by the fact that the ventilation grill for a system with natural and forced ventilation, comprising a housing with a hole for natural ventilation with horizontal blinds made in the form of flat fixed plates, and holes for connecting the duct, fasteners to building structures.

What is new in the utility model is that the ventilation grill for a system with natural and forced ventilation is equipped with a movable blocking mechanism consisting of two interacting flat sectional shutters for blocking the duct connection hole and the natural ventilation hole with horizontal shutters, while the shutter sections are paired with the help of the rotation axes installed in the housing and located parallel to each other, and the mechanism.

Description

The utility model relates to the field of civil engineering, namely to ventilation grilles in systems with a forced exhaust device.

In the process of cooking, various combustion products are released that can adversely affect human health.

Being in a room with a high content of air of combustion products, evaporation and carcinogens can adversely affect well-being and performance, which leads to rapid fatigue and reduced concentration.

Known ventilation grille (http://moydodir-yar.ru/catalog/view.php?id=21_47&frommarket=&ymclid=118690058281566953900001, accessed 11/28/2017), containing a housing and a hole for connecting the duct, fasteners to building structures.

The disadvantage of this design is the lack of preservation of natural ventilation in the room.

The closest in technical essence of the claimed device is a ventilation grill (http://www.ventek23.ru/catalog/ventilation/airdistributors/ventilationgrilles/era-item-198.html., Accessed 11/28/2017), containing a housing with a hole for natural ventilation with horizontal blinds made in the form of flat fixed plates and holes for connecting the duct, fasteners to building structures.

The disadvantage of the described design is the effect of reverse traction in the room with the forced draft device turned on, which worsens the microclimate and sanitary conditions for people in the room.

The technical result, which the utility model aims to achieve, is to improve the microclimate and sanitary conditions for people in the room by eliminating the effect of backdraft in the room when the exhaust device is turned on, due to the closure of the opening for natural ventilation and preventing the injection of air into the room.

The technical result is achieved by the fact that the ventilation grill for a system with natural and forced ventilation, comprising a housing with a hole for natural ventilation with horizontal blinds made in the form of flat fixed plates and holes for connecting the duct, fasteners to building structures.

What is new in the utility model is that the ventilation grill for a system with natural and forced ventilation is equipped with a movable blocking mechanism consisting of two interacting flat sectional shutters for blocking the duct connection hole and the natural ventilation hole with horizontal shutters, while the shutter sections are paired with help of the rotation axes installed in the housing and located parallel to each other, and the mechanism for returning to the initial position beyond tvorov, in which the hole for connecting the duct is blocked and the hole for natural ventilation with horizontal blinds is open.

The proposed utility model is illustrated by drawings, where

in FIG. 1 is a general view of a ventilation grill for a system with natural and forced ventilation;

in FIG. 2 - movable overlapping mechanism.

The ventilation grill for a system with natural and forced ventilation contains a housing 1 (Fig. 1) with an opening for natural ventilation with horizontal blinds 2 (Fig. 1), made in the form of flat fixed plates and holes 3 (Fig. 1) for connecting the duct.

Also, the ventilation grill for a system with natural and forced ventilation contains fasteners to building structures (not shown).

The ventilation grill for the system with natural and forced ventilation is equipped with a movable blocking mechanism 4 (Fig. 2), consisting of a flat sectional shutter 5 (Fig. 2) for blocking the hole 3 for connecting the duct (Fig. 1) and the flat sectional shutter interacting with it 6 (Fig. 2) for overlapping openings for natural ventilation with horizontal blinds 2 (Fig. 1).

Sections 7, 8 (Fig. 2) of a flat sectional shutter 5 (Fig. 2) are connected in pairs by rotation axes 11, 12 (Fig. 2) with sections 9, 10 (Fig. 2) of a flat sectional shutter 6.

The axis of rotation 11, 12 (Fig. 2) installed in the housing 1 (Fig. 1) and located parallel to each other.

The ventilation grill for a system with natural and forced ventilation contains a mechanism for returning to the initial position (not shown) flat sectional shutters 5, 6 (Fig. 2), made in the form of two springs (not shown), with one end of each spring connected to the axis rotation 11 or 12 (Fig. 2), and the other with the housing 1 (Fig. 1).

The described device operates as follows.

When you turn on the forced exhaust device, the air stream opens the flat sectional shutter 5 (Fig. 2) of the air duct connecting hole 3 (Fig. 1) and closes the sectional shutter 6 (Fig. 2) of the natural ventilation hole with horizontal blinds 2 (Fig. 1), due to the rotation of the axis of rotation 11, 12 (Fig. 2) with sections 7, 8, 9, 10 (Fig. 2), thereby eliminating the effect of reverse traction.

When the forced exhaust device is turned off, the air flow weakens and, due to the return mechanism (not shown) of the flat sectional shutters 5, 6 (Fig. 2), closes the shutter 5 (Fig. 2) of the hole 3 (Fig. 1) of the duct connection and opens shutter 6 (Fig. 2) openings for natural ventilation with horizontal blinds 2 (Fig. 1) due to rotation of the axes of rotation 11, 12 (Fig. 2) with sections 7, 8, 9, 10 (Fig. 2).

The use of a ventilation grill for a system with natural and forced ventilation will improve the microclimate and sanitary conditions for people in the room by eliminating the effect of backdraft when the exhaust device is turned on.
