Description

[Detailed explanation of the idea] This invention relates to a ventilation system.

Traditionally, indoor ventilation has been achieved by installing ventilation holes on the exterior wall surface above the window, but when a shutter is attached to the window for the purpose of crime prevention, indoor concealment, etc., the shutter case is installed in the ventilation hole above the window. This poses a problem in that indoor ventilation is not possible due to the blockage.

Therefore, the purpose of this invention is to provide a ventilation system that can continue to ventilate the room through the ventilation opening above the window even when a shutter is attached to the window.

An embodiment of this invention will be described with reference to FIGS. 1 and 2. That is, this ventilation device
As shown in the figure, a ventilation opening 3 is provided on the outer wall surface 2 above the window 1, a ventilation louver 4 is fitted, and the ventilation opening 3
The shutter case 5 is attached to the outer wall surface 2 so as to cover the
is attached, and the mesh plate 6 is fixed to the lower surface of the shutter case 5 with screws 7. In this case, as shown in FIG. 2, the shutter case 5 is constructed in the form of a box with an open bottom and rear surface, and the rear surface is fixed to the outer wall surface 2. In addition, the mesh board 6 is made of punching metal, expanded metal, etc., and
A shutter main body feeding space 8 is opened between the shutter case 5 and the shutter case 5, and screws are secured to the lower surface of the shutter case 5. Furthermore, guide rails 9 extending vertically along the outer wall surface 2 are provided on both sides of the feeding space 8 .
Furthermore, a shutter main body winding shaft 11 is arranged in the space 10 between the shutter case 5 and the mesh plate 6, one end of the shutter main body 12 is fixed to the winding shaft 11, and the other end of the shutter main body 12 is fixed to the winding shaft 11. It is pulled out from the feeding space 8 and held on both sides by the guide rails 9. The shutter take-up shaft 11 may be driven either electrically or manually.

As a result of this configuration, when a shutter is attached to the outside of the window 1, the shutter case 5 will cover the outside of the ventilation port 3, but the ventilation port 3 is connected to the shutter case 5 and the screen plate 6. Since it is communicated with the outdoors 13 through the intervening space 10 and the mesh of the net plate 6, indoor ventilation can be continued through the ventilation route. Moreover, even if the rainwater adhering to the shutter body 12 drips onto the mesh plate 6 when the shutter body 12 is wound up on a rainy day, the rainwater will not be absorbed by the mesh plate 6.
Since water is drained outdoors 13 through the mesh, the rust prevention effect on the inner peripheral surfaces of the shutter case 5 and the mesh plate 6 can also be improved. Furthermore, even if rainwater remains on the surface of the shutter body 12, it is quickly evaporated and dried by the ventilation flow flowing within the space 10, so that the rust prevention effect of the shutter body 12 can be improved. Furthermore, since the ventilation opening 3 is covered by the shutter case 5, the rain protection performance is improved, and the shutter case 5
This can also serve as an eaves for window 1.

As described above, the ventilation system of this invention consists of an outer wall with a ventilation hole above the window, and a box-shaped shutter with an open bottom and rear surface whose rear surface is attached to the outer wall surface so as to cover the ventilation hole. A mesh plate is attached to the lower surface of the shutter case with a space for feeding out the shutter body between the case and the outer wall surface, and a mesh plate is installed in a space surrounded by the shutter case and the mesh plate, and the shutter body is fed out in the space surrounded by the shutter case and the mesh plate. Since the shutter main body is equipped with a winding shaft that is driven to wind up and unwind from the space, even if the shutter is attached to a window, the ventilation opening above the window can continue to ventilate the room.
