Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator in which a ventilation duct is arranged inside a wall for ventilation inside and outside a building.

[0002]

2. Description of the Related Art In a conventional ventilation device, a ventilation duct is arranged in a wall to communicate the inside and outside of a building, and
A ventilation fan is installed on the indoor side of the ventilation duct, and a weather cover for rain protection etc. is installed on the outdoor side. In particular,
A ventilation device used in a bathroom or the like is installed above a window in order to improve its ventilation efficiency.

[0003]

However, in the conventionally used ventilation device, the weather cover exposed to the outside has a design such as the outer wall of the building or the entire building because of the shape and material required for its function. Often out of harmony,
In many cases, the aesthetics of the building were impaired. In particular, in a modern building system in which windows and outer walls are unitized and these designs are harmonized, there has been a problem that the conventional ventilation device exposing the weather cover breaks such harmony.

On the other hand, there has been proposed a structure in which a retractable shutter device is used for a shutter of a window and a shutter cover, which is a housing portion of the shutter, is arranged above the window. In such a structure, the designs above the window in which the conventional ventilation device is arranged and the window in which the shutter cover is arranged may be ununiform and unsightly.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ventilator capable of forming a building having an excellent appearance by unifying the external appearance of the window in which the ventilator is arranged and the window with another shutter cover. .

[0006]

According to another aspect of the present invention, there is provided a ventilation device, wherein the ventilation duct of the ventilation fan is covered with a duct cover having an open bottom, and the outer appearance of the duct cover is arranged above another window. The above problem is solved by making the appearance of the cover uniform.

[0007]

[Function] Since the ventilation duct of the ventilation device exposed on the outer wall above the window is covered with the duct cover and the outer appearance is similar to that of the shutter cover of other windows, the design of the outer wall of the building is unified. Will be things.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a first embodiment of a ventilation device according to the present invention will be described with reference to the drawings. FIG. 1 is a side sectional view of the ventilation device of this embodiment, FIG. 2 is an upper sectional view of the ventilation device, and FIG.

The ventilation device 1 is mounted on the wall 30 of the house, right above the window 40. The ventilation device 1 is provided on the ventilation duct 2 communicating between the inside and outside of the house and on the indoor side of the ventilation duct 2. The ventilation fan 3 is attached, the chamber box 4 is attached to the outdoor side, and the duct cover 5 covers the outside of the chamber box 4.

The ventilation duct 2 is arranged in the wall 30 just above the window 40, and the inside is divided into an exhaust passage 2A and an air supply passage 2B by a partition plate 2a. The ventilation duct 2 is provided with caulking 31 made of urethane foam between the ventilation duct 2 and the wall 30 in order to enhance airtightness. In addition, a fuse damper 2b that blocks the ventilation duct 2 in the event of a fire is arranged in the ventilation duct 2. The ventilation fan 3 is attached to the indoor side of the ventilation duct 2, and the power source is a cord 3a.
It is supplied from an electric wire in a wall (not shown).

The chamber box 4 is a box body having an open bottom, and is attached to the exhaust duct 2A side of the ventilation duct 2. The duct cover 5 also has a horizontally long opening 5c on the bottom 5b of the box-shaped main body 5a.
A mesh-shaped expanded metal 5d is fitted in c.

The air supply passage 2B of the ventilation duct 2 is opened in the duct cover 5 outside the chamber box 4. Therefore, the exhaust air from the ventilation fan 3 is made from the opening 5c of the duct cover 5 via the exhaust passage 2A and the chamber box 4, whereas the air for air supply, on the contrary, is opened 5c of the duct cover 5. Is taken in from both sides and is supplied to the room through the air supply passage 2B.

The design of the appearance such as the shape and color of the duct cover 5 is selected to be the same as or similar to the design of the shutter cover of the roll-up type shutter device attached to another window. The duct cover 5
Is adjusted to be the same as the width of the window 40.

The installation state of the ventilation device 1 is shown in FIG. Although two windows are shown in the figure, the ventilation device 1 is attached to the upper part of one of the windows 40A and the other window 40A.
A retractable shutter 50 is attached to the upper part of B. In this way, the duct cover 5 of the ventilation device 1,
Since the design of the retractable shutter 50 is the same as that of the shutter cover 51, the exterior of the house outdoor wall can be unified. Further, since the air supply and exhaust of the ventilation device 1 are performed below the duct cover 5 while unifying the appearance, it is possible to reliably prevent the entry of wind and rain into the ventilation duct 2.

In this embodiment, the chamber box 4 is used to distinguish between exhaust and air supply. However, without using the chamber box 4, a partition plate is used to directly supply the inside of the duct cover 5 to the exhaust side. Of course, it may be divided on the air side. That is, in the ventilation measures for exhausting and supplying air, the ventilation sections can be freely laid out in the duct cover 5.

A second embodiment of the present invention is shown in FIG. Figure 4
[Fig. 6] is a side sectional view of a ventilation device according to a second example. In this embodiment, the conventional ventilation device is applied to configure the ventilation device of the present invention.

The ventilator 11 is the ventilator 1 of the first embodiment.
Similarly, it is mounted on the wall 30 of the house, just above the window 40. The ventilation device 11 includes a ventilation duct 12 that communicates the inside and outside of a house, a ventilation fan 13 that is attached to the indoor side of the ventilation duct 12, a weather cover 6 that is attached to the outdoor side, and the weather cover. 6 and a duct cover 5 that covers the outside.

Unlike the ventilation duct 2 of the first embodiment, the ventilation duct 12 of this embodiment is an exhaust-only duct. However, the fuse damper 12b is arranged in the ventilation duct 12 as in the first embodiment. The ventilation fan 13 is powered by connecting the cord 13a to the outdoor outlet 7 on the outer wall.

The weather cover 5 is a box having an open bottom, and the air exhausted from the weather cover 5 is exhausted to the outside through the opening 5c of the duct cover bottom 5b. A mesh-shaped expanded metal 5d is fitted into the opening 5c. It is needless to say that the design of the outer shape such as the shape and color of the duct cover 5 is selected to be the same as the design of the shutter cover of the roll-up type shutter device attached to another window.

[0020]

As described above in detail, depending on the ventilation device of this embodiment, the exterior of the duct cover is consistent with the exterior of the shutter covers of other windows, so that The aesthetics can be excellent.

Further, in such a ventilation device, the exhaust passage and the air supply passage can be easily laid out by freely partitioning the inside of the duct cover. Furthermore, the duct cover can reliably prevent wind and rain from entering the ventilation duct.
