Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for preventing condensation from forming on a wall surface or the like within a ceiling.

[Problems to be solved by this invention]

Inside the ceiling of a building, there are many walls that are in contact with the outside air, so the hot and humid air that collects inside the ceiling is cooled and is prone to condensation. Therefore, various problems arise due to dew condensation, such as damage to interior ceiling materials due to rotten water.

If a dehumidifying device or the like is provided to deal with this problem, there is a problem in that costs such as equipment costs and operating costs increase.

This invention was devised in view of the above-mentioned circumstances, and its purpose is to provide a prevention device that is inexpensive and can reliably prevent dew condensation within the ceiling.

[Means for solving problems]

In this invention, a dew condensation prevention device in a ceiling is formed by forming a material with good thermal conductivity into a box shape with an open top, and connecting it to a condensation part installed in the ceiling of a building and a bottom wall of this box-shaped dew condensation part. A drain pipe made of a material with good thermal conductivity that extends outside the building and is integrally formed with a heat sink on the outside of the building, and attached to the outer circumferential surface of the condensation part excluding the opening and the outer circumferential surface of the drain pipe inside the building. It consists of a heat insulating material.

The hot and humid air accumulated in the ceiling is actively induced to form condensation in the dew condensation section, thereby preventing dew condensation from occurring within the ceiling.

〔Example〕

The present invention will be explained below with reference to illustrative embodiments.

The prevention device 1 in the ceiling is formed into a box shape made of a material with good thermal conductivity with an open top, and includes a dew condensation part 4 installed in the ceiling 3 of the building 2, and a bottom wall 4a of this box-shaped dew condensation part 4. A drain pipe 5 made of a material with good thermal conductivity is connected to the drain pipe 5 and extends outside the building, and is integrally formed with a heat sink 5a on the outside of the building. It consists of a heat insulating material 6 attached to the outer peripheral surface inside the building.

The dew condensation part 4 is made of a metal with good thermal conductivity and has a rectangular opening surface, and the bottom wall 4
A drainage hole 4b into which the drainage pipe 5 is fitted is approximately in the center of a.
It has a hole in it and looks beautiful.

Further, the drain pipe 5 is provided with an S-shaped trap portion 5b inside the building.

The effect of preventing dew condensation in the ceiling by the prevention device 1 having such a configuration is that when hot and humid air accumulated in the ceiling 3 enters the dew condensation part 4 from the opening and comes into contact with it, the dew condensation part 4 dissipates heat. Since it is cooled by the drain pipe 5 cooled by the plate 5a, the moisture is connected and adheres as water droplets.

Note that since a heat insulating material 6 is attached to the drain pipe 5 and other than the opening surface of the dew condensation section 4, dew condensation will not occur on that surface.

Next, the water droplets adhering to the inside of the dew condensation section 4 flow from the drain hole 4b of the bottom wall 4a to the drain pipe 5, and are discharged to the outside of the building 2.

The hot and humid air that has accumulated in the ceiling in this way is cooled in the dew condensation section 4 and actively induced to condense, and the moisture adheres as water droplets and is discharged outside the building through the drain pipe 5. Ru.

Therefore, the inside of the ceiling 3 is dehumidified, and it is possible to prevent the air inside the ceiling 3 from being cooled and condensing.

The indoor dew condensation prevention device of the present invention is not limited to the configuration of the above-described embodiments, and is applicable within the scope of the claims.
Any device may be used as long as it has a configuration within the range described in the column. Furthermore, the installation location is not limited to that of the embodiment described above.

〔Effect of the invention〕

By installing a condensation section in the ceiling where hot and humid air accumulates, a drain pipe that extends outside the building and has a heat sink is installed, and the air inside the ceiling is introduced into this condensation section. It is possible to inexpensively and reliably prevent condensation inside the ceiling.

That is, the air in the ceiling is cooled by the dew condensation part to actively induce condensation, and the moisture is separated as water droplets and discharged to the outside through the drain pipe. Therefore, the air within the ceiling is dehumidified, and it is possible to reliably prevent dew condensation from occurring within the ceiling.

Further, since the box-shaped dew condensation part is simply installed in the ceiling and a drain pipe is provided, the structure can be simple, and the dew condensation prevention device can be provided at low cost.
