JPH1193285A - Ventilation device of clearance between external wall and internal wall material of building - Google Patents

Abstract

PROBLEM TO BE SOLVED: To protect the property, the health and the environment of an inhabitant by preventing dew condensate in a clearance between an external wall and an internal wall material and damage of the internal wall material caused by the moisture on discharging outdoors the humid air generated from the dew condensate, and preventing molds and ticks bred indoors by the moisture. SOLUTION: A cylinder 1 is inserted in a hole D opened so as to be pierced from an external wall A of a building to an internal wall material B to be arranged on its inside with a clearance C therebetween from the indoor side, a hole 3 is locally provided in a part corresponding to the clearance C of a body 2 of the cylinder 1, one end of the cylinder 1 on the indoor side is sealed, and a fan 5 driven by a motor 4 is provided on the outdoor side of the cylinder 1, and operated. The humid air generated in the clearance C is discharged outside through the hole 3 provided in the body 2 of the cylinder 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to ventilation of humid air caused by condensation formed in a gap C between an outer wall A and an inner wall material B of a building, thereby preventing dew condensation and damaging the inner wall material B by the moisture of the condensation. The present invention also relates to a ventilating device in a building, which makes it possible to prevent indoor air from being contaminated by preventing mold generated by moisture, mites generated by mold, and the like.

[0002]

2. Description of the Related Art Conventionally, a dehumidifier, a ventilation fan, a hygroscopic wall material or a heat-insulating wall material has been used to prevent mold and dew condensation occurring in a room, but a gap C between an outer wall A and an inner wall material B has been used.
There is no way to ventilate the moisture generated in the wall, and the wall must be repaired when the wall material is damaged by the moisture or the wallpaper is damaged due to the generation of mold.

[0003]

The present invention ventilates the moisture generated in the gap C between the outer wall A and the inner wall material B, which could not be solved by the above technology, thereby preventing dew condensation on the inside of the skeleton and drying the inner wall material B. By doing so, the inner wall material B can be prevented from being damaged.
By preventing ticks generated by mold, it is also possible to prevent the indoor air from being polluted.

[0004]

Means for Solving the Problems A cylinder 1 is inserted from the indoor side into a hole D formed so as to penetrate an outer wall A of a building and an inner wall member B disposed inside the outer space A with a gap C therebetween. A hole 3 is partially formed in the body 2 in a portion corresponding to the gap C.
Is provided, and one end of the cylinder 1 on the indoor side is sealed, and a fan 5 rotating by the operation of the motor 4 is provided on the outdoor side of the cylinder 1 to operate, so that the moist air generated in the gap C is removed from the cylinder 2. It is possible to exhaust air to the outside through the hole 3 provided in the hole.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a ventilating apparatus according to the present invention.

A hole D is formed so as to penetrate to the outer wall A of the building and to the inner wall material B disposed inside with a gap C therebetween.
The cylinder 1 is inserted into the cylinder 2 from the indoor side, and a hole 3 is partially provided in the body 2 of the cylinder 1 at a portion corresponding to the gap C. One end of the cylinder 1 on the indoor side is sealed, and the motor 4 A cylinder sealed at one end on the indoor side which enables a fan 5 to be rotated by operation and enables the humid air generated in the gap C to be exhausted to the outside through the hole 3 provided in the body 2 of the cylinder 1 by operating. 1, the motor 4, and the fan 5 are integrally formed.

[0007]

According to the first aspect of the present invention, the dew formed on the outer wall side of the gap C between the outer wall A and the inner wall material B of the building is evacuated by the humid air to the outside to prevent dew condensation on the inner side of the outer wall. It is possible to prevent the inner wall material B from being damaged by air.
In addition, we can protect resident's health by preventing mold generated by moist air and mites caused by mold,
Also, by preventing the inner wall material from being damaged by moisture, the repair cost can be greatly reduced.
