Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a ventilation system for ventilating an attic, a room, etc. of a building.

[Background technology]

Conventionally, a ventilation device is provided on the roof to ventilate the attic and the like. As a ventilation system,
Some have ventilation holes in the roof and cover these ventilation holes with rain covers.

However, the cover only had a ventilation window in one place, and air circulation between the inside and outside of the cover was poor. Therefore, there was a problem in that the ventilation performance was poor in taking outside air into the attic and discharging the air from the attic to the outside.

Another problem was that rainwater that had flowed into the cover from the ventilation window entered the attic through the ventilation opening, resulting in poor rain drainage.

[Purpose of the invention]

An object of the present invention is to provide a ventilation device that allows good air circulation between the inside and outside of a cover, improves ventilation performance, and has good rain control.

[Disclosure of the invention]

The ventilation system of this invention is provided with a ventilation opening in the roof, a hood with a ventilation opening on the upper surface covering the ventilation opening, a cover provided over the hood, and a pair of hoods on opposite sides of the cover. Each hood is provided with a ventilation window, and a drain plate is provided between the ventilation window and the ventilation opening to allow rainwater that has entered the cover from the ventilation window to fall onto the top surface of the hood excluding the ventilation opening. According to the configuration of this invention, the following effects are achieved. Since ventilation windows are provided on opposite sides of the cover, outside air can easily pass through the inside of the cover, and air can flow in and out between the inside and outside of the cover. Therefore, air intake and exhaust from the ventilation opening can be carried out efficiently, and ventilation performance is improved.

In addition, since the ventilation opening is covered with a hood and a cover, it has a double structure, so even if rainwater blows into the cover from the ventilation window, the hood blocks it and prevents rainwater from entering the attic through the ventilation opening. At the same time, we have installed a drain plate that allows rainwater that has entered the cover through the ventilation window to fall onto the top surface of the hood, excluding the ventilation openings, to prevent rainwater from entering the hood through the ventilation openings of the hood. Finishing performance improves.

According to the ventilation system configured in this way, the ventilation window 1 is provided on the wall panels 50 and 52 facing each other in the cover 16.
8 and 20, for example, as shown in FIG. Air circulation between the inside and outside is improved. Therefore, Juan 2
9, the outside air that has entered the cover 16 through the ventilation window 18 is sucked into the hood 36 through the ventilation opening 38 of the hood 36, passes through the intake pipe 24 through the upper opening 34, and enters the attic 30 through the lower opening 28. be forcibly introduced. When outside air is introduced into the attic 30, the warm air that has been in the attic 30 is discharged from the lower opening 26 through the exhaust pipe 22 and into the hood 36 from the upper opening 32. The air discharged into the hood 36 reaches the inside of the cover 16 through the ventilation opening 38 and is led out to the outdoors through the ventilation window 20, thereby cooling the attic 30. In this way, cover 1
When the circulation of air between the inside and outside of the roof 6 improves, the flow of air between the outside and the attic 30 also improves, improving the intake and exhaust efficiency and improving the ventilation performance. That is, the attic 30 can be cooled with outside air to cool the inside of the building, or the attic 30 can be prevented from becoming damp.

In addition, since the exhaust pipe 22 and the intake pipe 24 are covered with the hood 36 and the cover 16 in a double structure, even if rainwater enters the cover 16 through the ventilation windows 18 and 20 of the cover 16, the ventilation opening of the hood 36 can prevent rainwater from entering the cover 16. Since there is a distance to the portion 38, the liquid falls on the slope 37 on the upper surface of the hood 36 and flows through the hood 36 to the outside of the cover 16. Moreover, ventilation window 1
Since the louvers 8 and 20 are provided with louvers 74 and 66, rainwater can be prevented from entering the attic 30 through the exhaust pipe 22, the intake pipe 24, and the ventilation openings 12 and 14, and rainwater can be effectively shut off.

In addition, since the draining plates 70 and 76 are provided, floating rainwater droplets blown into the cover 16 from the ventilation windows 18 and 20 hit the draining plates 70 and 76, collect with other water droplets, and flow onto the inclined surface 37 of the hood 36. Fall.
The fallen water drops flow through the hood 36 to the outside of the cover 16. In this way, the draining plates 70, 76
By providing this, rain water can be blocked and only outside air can be introduced into the hood 36 through the ventilation opening 38, improving rain protection.

Furthermore, the cover 16 is provided by fixing the wall panels 52, 50 to the hood frame 36' with mounting members 54, 72, respectively, and fixing the wall panels 84, 82 to the hood frame 36' with mounting members 86, 96, respectively. It is being In this way, the cover 16 is directly connected to the roof 1.
Since it is not fixed at 0, when a load is applied to the cover 16 from the outside, the cover 16 tilts to follow the external force, and when the external force disappears, it returns to its original position and responds flexibly. Therefore, the strength of the cover 16 against external forces, changes over time, repeated heating and cooling, etc. is improved.

Note that the ventilation pipe 24 may not be provided with the fan 29 and natural ventilation may be provided, or the ventilation port may simply be provided in the roof 10 without passing the pipe.

In addition, an intake pipe is provided in the ventilation port 12, and the ventilation port 14 is provided with an intake pipe.
An exhaust pipe may be provided.

Further, in this embodiment, the ventilation holes 12 and 14 are arranged side by side in the direction of inclination of the roof 10, but they may be arranged in a direction perpendicular to the direction of inclination of the roof 10.

Further, ventilation holes may be provided in the upper portions of the wall panels 82 and 84 of the cover 16 so that outside air can enter from the entire circumference of the cover 16.

Furthermore, the cover 16 may be fixed directly to the roof 10.

Second Embodiment A second embodiment of the present invention will be described based on FIG. 12. Note that the same parts as in the first embodiment are denoted by the same reference numerals, and the explanation thereof will be omitted. That is, in the ventilation system of this embodiment, a support rod 120 is provided upright on the upper surface of the roof 10 with the upper part protruding upward from the ventilation opening 38 of the hood 36, and a rotary rod 126 is provided at the upper end of the support rod 120. A wind direction plate 122 is provided at the upper end of this rotating rod 126, and a draining plate 124 is provided on the rotating rod 126. Draining board 124
is provided with its lower end located above the inclined surface 37 of the hood 36, and is formed in a size that allows it to rotate within the cover 16 and face the ventilation windows 18, 20. Note that the other configurations are similar to those of the first embodiment shown in FIGS. 1 to 11.

The ventilation system configured in this manner also provides the same effects as the first embodiment.

Furthermore, since the wind direction plate 122 is provided on the drain plate 124, the drain plate 124 faces windward, and the ventilation window 18,
It can really block the rainwater coming in from 20. Moreover, since the drain plate 124 always faces upwind in the wind direction plate 122, only one drain plate 124 is required to cover both ventilation windows.
It is possible to shield rainwater from entering from 8 and 20. In this way, since only one draining plate 124 is required, outside air can easily pass through the inside of the cover 16.

Note that the ventilation opening 38 of the hood 36 may be formed to a size that allows it to be completely covered by the draining plate 124. In addition, a wind direction plate 122 and a draining plate 124
may be provided on a rotary rod rotatably attached to the roof panel 78.

〔Effect of the invention〕

According to the ventilation device of the present invention, the following effects can be obtained.

Since ventilation windows are provided on opposite sides of the cover, air can easily pass through the cover, improving air circulation between the inside and outside of the cover. Therefore, air intake and exhaust from the ventilation opening can be carried out efficiently, and ventilation performance is improved.

Since the ventilation opening is covered with a hood and a cover, it has a double structure, so even if rainwater blows into the cover from the ventilation window, it will be blocked by the hood, preventing rainwater from entering the attic etc. from the ventilation opening. A drainage plate is installed to allow rainwater that has entered the cover through the ventilation window to fall onto the top surface of the hood, excluding the ventilation openings, to prevent rainwater from entering the hood through the ventilation openings. will improve.
