Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a ventilation system for an attic, with particular consideration given to rain protection.

[Prior art and problems]

Conventionally, a ventilation ridge was installed on the roof, and a ventilation tube was installed inside the ventilation ridge to ventilate the attic of the roof.
For example, as described in Japanese Patent Publication No. 60-11194, it is known that a camp hat or inner hat is installed above or below the ventilation ridge to prevent the intrusion of wind and rain.

However, in a ventilation system equipped with such a jinkasa or inner kasa, although it may be okay in case of light wind and rain, in the event of a storm such as a typhoon, sideways wind and rain can enter through the ventilation openings below the jinkasa or inner kasa. There was a problem with wind and rain getting into the attic.

[Means for solving the problems] The present invention solves the problems of the above-mentioned conventional technology,
This system prevents wind and rain from reaching the attic even if they enter through the ventilation openings during a rainstorm.The gist is that a ventilation ridge with a ventilation opening is installed in the roof ridge; An upright blower tube with a built-in blower is provided, the upper opening of the upright blower tube is opened into the ventilation ridge, the lower outlet of the upright blower tube is communicated with the attic below the roof ridge, and the upper opening of the upright blower tube is opened into the ventilation ridge. This attic ventilation system is characterized in that a shielding wall is installed vertically from above the ventilation ridge between the opening and the ventilation opening, and the lower end of the shielding wall is located below the upper opening of the upright blower. .

In the present invention, the ventilation opening is not only provided on the girder side of the ventilation ridge as in the illustrated embodiment, but also may be provided on the girder side of the ventilation ridge.

In the present invention, the power source for the blower may be a solar cell as in the illustrated embodiment, or may be a general AC power source.

In the present invention, how far below the upper opening of the blast tube the lower end of the shielding wall should be depends on the distance between the outer surface of the blast tube and the shielding wall, but for example, the distance between the outer surface of the blast tube and the shielding wall is If the distance from
If the distance between the outer surface of the blower tube and the shielding wall is about 100mm, the lower end of the shielding wall should be about 100mm lower than the upper opening of the upright blower tube, the wind speed will be 30m/sec. It has been confirmed through experiments by the present inventors that it can withstand even rainstorms with a rainfall of about 240 mm/hour.

[Effect]

In the present invention, a ventilation ridge with a ventilation opening is provided in the roof ridge, an upright blower tube with a built-in blower is provided in the ventilation ridge, and an upper opening of the upright blower tube is opened in the ventilation ridge, Since the lower opening of the upright blower is communicated with the attic below the roof ridge, air is discharged from the attic through the upright blower in the ventilation ridge and from the ventilation opening to ventilate the attic.

In addition, a shielding wall is vertically installed from above the ventilation ridge between the upper opening of the upright blower and the ventilation opening, and the lower end of the shielding wall is below the upper opening of the upright blower, so that in the event of a horizontal rainstorm. Furthermore, even if wind and rain enter through the ventilation openings, they will be blocked by the shielding wall and will not reach the inside of the upright blower.

In these drawings, 1 is the roof, 2 is the roof 1
This is a ventilation building built on top of the building.

There are many solar cells 3 on the roof slope of the ventilation building 2.
3,... are provided.

Ventilation louvers 21 are provided on both end sides of the ventilation building 2, and the ventilation louvers 21 are provided with ventilation ports 22, 22, . . . consisting of a large number of holes.

Reference numeral 4 denotes an upright blower tube provided inside the ventilation ridge 2, and a blower 41 having blower blades 411 is installed inside the upright blower tube 4, and the blower 41 connects the solar cells 3,
3, . . . is operated by the electric power generated by .

An upper opening 42 at the upper end of the upright blower tube 4 is opened upward.

11 is a pedestal installed at the ridge of roof 1;
A lower opening 43 at the lower end of the upright blower tube 4 is attached to a mounting seat 111 provided at the center of the pedestal 11. The inside of the upright blower tube 4 communicates with the attic 5 below the roofing material 12 through a lower opening 43 at the lower end and a hole 121 provided in the roofing material 12.
When the blower blade 411 of No. 1 rotates, it blows air from the attic 5 to hole No. 1.
21 and the upright blower tube 4, air flows into the ventilation building 2 and is exhausted through ventilation ports 22, 22, . . . .

Reference numeral 6 denotes a shielding wall, and the shielding wall 6 is vertically installed from the attic of the ventilation ridge 2 at a distance of 100 mm from the outer surface of the upright fan 4 between the upright fan 4 and the ventilation louvers 21, 21 on both sides. The lower end of the shielding wall 6 is located 100 mm below the upper opening 42 of the blower tube 4.

A thin plate 112 of pentite steel is stretched on the upper surface of the pedestal 11 as a drainage material.

7 is a drainer made of an aluminum plate installed around the lower part of the upright blower tube 4, and is connected to the ventilation louvers 21, 2.
Even if wind and rain enters through the ventilation openings 22, 22, .
The water is transferred from the side surface to the drainer 7, and from the drainer 7 to the upper surface of the pedestal 11, so that water does not flow down the side surface of the upright blower tube 4.

A slight gap (a) is provided between the lower end of the ventilation louver 21 and the roof 1, and rainwater accumulated on the upper surface of the pedestal 11 flows down from the gap (a) onto the roof material 12.

〔effect〕

In the present invention, a ventilation ridge with a ventilation opening is provided in the roof ridge, an upright blower tube with a built-in blower is provided in the ventilation ridge, and an upper opening of the upright blower tube is opened in the ventilation ridge, Since the lower opening of the upright blower is communicated with the attic below the roof ridge, air is discharged from the attic through the upright blower and through the ventilation opening to ventilate the attic.
