Description

[Detailed Description of the Invention] The present invention relates to an eave with a ventilator, and more specifically to a technique for housing the ventilator inconspicuously.

In today's homes, indoor ventilation is done through natural ventilation, except in the kitchen, which makes the living environment poor due to the polluted indoor air.
This air pollution has gradually become a problem as the quality of housing improves and airtightness increases.

However, drilling a hole in an exterior wall and attaching a conventional ventilation fan directly to the hole has not been used because it makes the building look unsightly and the ventilation fan is easily damaged by rain blowing in.

Therefore, the technology for installing a ventilation system inside the bottom was developed in 1973.
With the eaves disclosed in Japanese Patent No. 4027 and into which a ventilation system can be installed, it is not possible to easily clean or inspect the ventilation system.

The present invention has been made in view of the above-mentioned conventional example, and its purpose is to provide an eave with a ventilation system that allows the ventilation system to be easily cleaned and inspected.

The structure of the present invention is that a ventilation opening 3 is provided by opening the upper outer wall 2 of a window-like opening 1, a main body frame 8 is attached to the outdoor side of the ventilation opening 3, and the upper and front surfaces of the main body frame 8 are is covered with an eave roofing material 9, the rear end of the eave roofing material 10 is placed on a receiving tree 14 fixed to the outer wall 2, and the front end of the eave roofing material 10 is provided at the lower end of the eave roofing material 9. The eaves 4 is constituted by locking the main body frame 8 with the side plates 11 and blocking the sides of the main body frame 8 with the side plates 11.
In the eave with a ventilation device, the indoor side ventilation opening 6 of the ventilation device 5 arranged inside the eave 4 is provided on the indoor side of the ventilation opening 3, and the outdoor side ventilation lower of the ventilation device 5 is provided on the lower surface of the eave 4. can be,
The eave ceiling material and side panels can be removed from the main body frame to open the inside of the bottom without removing the eaves roof material from the main body frame.

The present invention will be explained in detail below with reference to the accompanying drawings.

In the figure, 1 is a window-like opening provided in the outer wall 2.
The upper outer wall 2 is opened to provide a ventilation opening 3.

Reference numeral 4 denotes an eave attached to the outer wall 2 so as to cover the outdoor side of the ventilation opening 3 by the rear surface, and is extended from the main body frame 8, the eave roofing material 9, the eave ceiling material 10, and the side plate 11.

That is, the main body frame 8 is first fixed to the outer wall 2 using concrete nails 12, etc., the top and front surfaces of the main body frame 8 are covered with the eaves roofing material 9, and splints 13 are attached to the rising piece 15 at the upper end of the eave roofing material 9. The upper end of the eave roof material 9 is fixed to the outer wall 2, the lower surface of the main body frame 8 is covered with the eave roof material 10, and the rear end of the eave roof material 10 is placed on the supporter 14 to secure the eave roof material 10. The rear end is fixed to the outer wall, a locking part 16 at the lower end of the eave roofing material 9 is locked to the lower surface of the front end of the eaves roofing material 10, and the side surface of the main body frame 8 is closed by a side plate 11.

Incidentally, it is preferable to seal the space between the rising piece 15 of the eave roof material 9 and the outer wall 2 with caulking material or the like.

Reference numeral 5 denotes a ventilation device fixed to the main body frame 8 and installed inside the eaves 4, which includes a ventilation pipe 17 having an indoor ventilation opening 6 and an outdoor ventilation lower at both ends, and a sirocco fan disposed inside the ventilation pipe 17. A ventilation fan 18 and a motor 19 located outside the ventilation pipe 17 and driving the ventilation fan 18 are provided.

Here, the indoor ventilation opening 6 side of the ventilation pipe 17 is fitted into the ventilation opening 3 of the outer wall 2, the indoor ventilation opening 6 is located on the indoor side, and the outdoor ventilation lower of the ventilation pipe 17 is located downward. It is open toward the outside and communicates with the outdoors via a through hole 20 provided in the eaves ceiling material 10.

Further, an indoor louver 21 is fitted into the indoor ventilation opening 6, and an outdoor louver 22 is fitted into the outdoor ventilation lower.

The indoor louver 21 and the outdoor louver 22 may be movable louvers whose louver plates are rotatable so that the direction of the louver plates can be freely changed.

Further, an operation switch (not shown) for the ventilation device 5 is provided indoors.

As mentioned above, the present invention is designed to ventilate the room by installing a ventilation device inside the eaves installed above the window-like opening, so the ventilation device is hidden behind the eaves and cannot be seen from outside. This has the effect that indoor ventilation can be carried out without damaging the appearance of the building.

In addition, the ventilation system is housed inside the eaves, and the outdoor ventilation opening is provided on the underside of the eaves, so the ventilation system is protected from rain and sunlight, making it less prone to breakdowns and damage.

Furthermore, since the eave ceiling materials and side panels can be easily removed from the main body frame, cleaning and inspection of the ventilation system can be done easily by removing the eave ceiling materials and side panels, and there is no need to remove the eave roof materials. This has the advantage that the main body frame and the operator will not get wet even if cleaning or inspection is carried out in the rain.
