Description

Field of technology to which the utility model relates

The utility model relates to the field of ventilation devices for premises and is intended to provide air exchange in residential, administrative and public premises.

State of the art

A solution is known in the existing state of the art (RU66488 U1, F24F 13/08, 09/10/2007). This ventilation valve contains a plastic pipe with a cylindrical through channel, configured to be installed in the outer wall of the room, an air purifying filter and a heat-insulating insert, which are located in the said plastic pipe.

The disadvantage of this valve is the inability to regulate the volume of air entering the room. The consequence is hypothermia of the room during severe frosts.

The closest analogue of the proposed utility model is a ventilation noise protection device (RU 30817 U1, E06B 7/02 07/10/2003). This device contains a hollow body with ventilation holes and a unit for adjusting the clearance of the ventilation hole, characterized in that the housing consists of a pipe installed at one end of the grille and installed at the other end of the partition with a ventilation hole, on which the clearance adjustment unit is installed, on a cylindrical The wall of the housing has a coating made of noise-absorbing material, and the device is equipped with a hollow cover mounted on the partition and having a hole on the wall, on which

there is an air filter and an adjustment knob connected to the height adjustment unit.

The disadvantages of this ventilation noise protection device are the complex mechanism of the clearance adjustment unit, which also limits the flow of air when the device is in the maximum open position, since the adjustment unit blocks part of the ventilation hole, and in strong gusts of wind, spontaneous blocking of the air channel is possible, since the petals of the adjustment unit , directed towards the air flow.

Obviously, there is a need for further improvement of ventilation devices that use outside air to ventilate rooms, to improve consumer properties and simplify the design in order to reduce its cost.

Therefore, it is necessary to develop ventilation devices that can solve these problems.

The purpose of the proposed utility model is:

1. Creation of a ventilation device that makes it possible to simplify the design, thereby reducing cost, while improving performance characteristics, due to a mechanism that, in the open position, will not impede the passage of air, will increase the reliability and information content of the degree of opening of the ventilation device.

2. Simplify the process of replacing and cleaning mesh and filter elements by installing them from inside the room. Otherwise, difficulties arise if the ventilation device is installed at a difficult-to-reach height.

The first task was solved by reducing the number of parts in the air flow control mechanism, since serial production of each part requires the manufacture of an expensive mold. The mechanism for adjusting the air flow of the proposed utility model uses only two parts, a damper consisting of four parts and a handle-plate. In this case, in the open position, the air flow control mechanism does not interfere with its passage through the ventilation duct. Also, the use of a minimum number of parts increases the reliability of the proposed utility model.

The handle-plate allows you to smoothly regulate the volume of air entering the room, and its position informatively shows the degree of opening of the ventilation duct.

The second problem is solved by placing a mesh filter with a handle at the base of the ventilation device. This filter serves to prevent insects and large debris from entering the housing of the ventilation device, thereby extending the service life of the main filter.

The location of the main and mesh filters from inside the room allows for timely and unhindered cleaning and replacement compared to the state of the art.

The ventilation device can be used in systems with natural exhaust ventilation and in systems with mechanical exhaust ventilation.

Implementation of a utility model

The ventilation device is a prefabricated structure (Fig. 1), which contains a ventilation grille (1), an air duct (2), heat and noise insulation of the air duct (3), a mesh filter (4), a base (5), dampers (6/1, 6/ 2, 6/3, 6/4), handle - plate (7), main filter (8), thermal and noise insulation of the housing (9), cover (10).

The air duct (2) of the ventilation device forms a through hole for the entire thickness of the outer wall, with an angle of inclination towards the street of 2-3° (for condensate drainage). The air duct (2) has a circular cross-section with a diameter of 130 mm and is made of plastic. In order to reduce the noise level and prevent the wall from freezing, heat and noise insulation of the air duct (3) is installed in the air duct (2).

Thermal and noise insulation of the air duct (3) can be made of foam rubber, basalt or other materials suitable for their characteristics. It has a round cross-section and is made in the form of a removable insert. Thermal and noise insulation of the air duct (3) with its outer diameter fits tightly to the inner surface of the air duct (2), and the internal diameter of the thermal and noise insulation of the air duct (2) forms the air channel (11).

The ventilation grille (1) is installed on the outside of the air duct (2) and is designed to protect against moisture and large debris getting inside the air duct (2).
