Description

Fixed type ventilator having flow inducer

The present invention relates to a fixed ventilation apparatus having a flow guide feather, it is possible to increase the ventilation performance to effectively ventilate the building.

Ventilation of the building is achieved when the wind passes through the end 2 of the vent 1, as shown in Figure 1, the static pressure at the end is lowered to suck the air inside the vent. At this time, the amount of air sucked out is proportional to the speed of the wind passing through the end of the vent, thereby providing the possibility of improving the ventilation performance by artificially increasing the speed of the wind passing through the end of the vent.

Conventional building ventilation is a circulation method using a centrifugal ventilation device rotated by wind, which is different from the present invention in its fundamental principle and technical configuration.

The present invention aims to improve the ventilation performance by increasing the speed of the wind regardless of the direction of the wind by attaching a flow guide feather to the fixed ventilation device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Figure 2 is a view showing a stationary ventilator having a flow guide vane of the present invention, the ventilator is a circular middle plate (4) with a hole in the center, a conical lower plate (5) with a hole in the center, the middle plate and the lower plate It consists of a flow guide feather (6) connecting the radiographically and the upper plate (3) to prevent rain water from seeping into the middle plate (4), the ventilator is the bottom plate of the ventilator (2) 5) is to be connected.

The stationary ventilator with flow guide collar is narrowed in cross section by the flow guide vane 6 while the wind enters the inlet 8 of the ventilator and passes through the central portion 7 of the ventilator, thereby increasing the speed. Lowering the static pressure in (2) and the wind passing through the central portion 7 diffuses through the hole 10 in the middle plate of the middle plate and the outlet 9 of the ventilator to induce the flow in the ventilator (1) to the performance of the ventilation It greatly improves, especially the ventilation performance is maintained regardless of the direction of the wind, there is no rotating part, easy maintenance, and there is no friction generated in the rotating part improves the ventilation capacity at low wind speed.

3 is a view illustrating the operation of a fixed ventilation apparatus having a flow guide vane of the present invention, and FIG. 3 (a) shows the path of the wind in the plan view of the present invention. The wind introduced between the lower and the upper portion of the ventilation device is guided by the flow guide feather 6 and passes through the central portion of the ventilation hole 10. At this time, the wind passes through the flow guide vanes to reach the ventilation hole, and the cross-sectional area gradually decreases, so that the speed at the ventilation hole is the fastest. As the wind speed increases, the static pressure is lowered, causing a large pressure difference between the inside of the ventilator and the ventilation hole, thereby improving the ventilation performance.

Figure 3 (b) shows the wind path on the side view of the present invention. As shown in Figure 3 (b), the circular middle plate with a hole in the center, the conical lower plate with a hole in the center, the flow guide feather (6) for connecting the middle plate and the lower plate in a radial manner and rainwater on the middle plate It prevents the back from infiltrating and consists of the top plate connected to the support plate on the middle plate. The wind path increases the speed by narrowing the cross-sectional area by the flow guide vanes 6 while the wind enters the inlet of the ventilator and passes through the center part of the ventilator, reducing the static pressure at the end of the vent hole and passing through the center part. The wind diffuses through the hole 10 in the middle of the middle plate and the outlet of the ventilator to induce a flow in the vent hole, thereby greatly improving the performance of the vent. In particular, as the flow is guided by the flow guide feather (6) regardless of the direction of the wind, the ventilation performance is maintained, there is no rotating part, easy to maintain, and there is no friction generated at the rotating part, so the ventilation ability at low wind speed is maintained. Improve.

The present invention maintains the ventilation performance regardless of the direction of the wind, it is easy to maintain because there is no rotating part, and there is no friction generated at the rotating part so that the ventilation ability at low wind speed is improved, and it is applicable to the ventilation opening of the building. Can be. In addition, the ventilation ability at low wind speed is superior to the existing rotary centrifugal ventilation device.
