Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit bathroom, and more particularly to a ceiling panel having a concave central portion which is suitable for preventing condensation water from falling during bathing.

[0002]

2. Description of the Related Art Conventionally, in a ceiling panel having a concave central portion, as a technique for preventing dew condensation water from falling overhead, an electric heater is provided on the back surface to generate heat, and the surface temperature of the ceiling inside the bathroom is controlled. It was necessary to prevent the condensation itself on the ceiling surface by setting the dew point or higher.

[0003]

The ceiling panel of the unit bathroom has a ceiling shape which is widened on the side opposite to the bathroom and has a concave shape when viewed from the room side in order to have a design and a feeling of expansion of the room. Ceiling panels are used. Usually, it is formed by vacuum molding or injection molding of FRP or thermoplastic resin. These resins usually have water repellency, and dew water on the surface of the ceiling panel is generated and grown in a ball shape, and eventually falls. Insulation treatment was applied to the back surface of the ceiling panel to prevent dew condensation, but it was not possible to prevent the dew condensation. However, it was necessary to attach an electric heater to the back surface of the ceiling panel and heat it to keep the ceiling surface at a temperature equal to or higher than the dew point. However, in this method, running costs such as electricity costs are required, and a work load such as electric wiring is generated even during construction. The present invention has been made to solve the above problems, and an object of the present invention is to provide a bathroom ceiling panel that prevents dew condensation water from falling into a bathroom without particularly using a heat source. .

[0004]

In order to achieve the above object, in claim 1, the surface of the ceiling panel is made hydrophilic so that dew condensation water is prevented from forming water droplets, and the concave shape of the entire ceiling panel is reduced. Utilizing this, the condensed water generated on the surface does not fall as water droplets on the head, but flows down the ceiling surface, flows to the upper end of the wall, and travels along the wall to be drained from the floor to the drain port.

According to a second aspect of the present invention, in the ceiling panel having a concave shape as a whole and having a partially horizontal surface portion, water droplets flowing from the concave portion to a boundary line with the horizontal surface portion are provided in that portion. It is guided to the upper end of the wall by the rain gutter-shaped formed body, and is drained from the floor to the drain through the wall.

According to the third aspect of the present invention, a part of the part of the rain gutter-shaped molded body which is not in contact with the ceiling panel is formed of a soft material, so that the part can be deformed, and the dirt accumulated in the rain gutter-shaped molded body can be removed. , Can be discharged during cleaning.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described to further clarify the contents of the invention described above. The bathroom ceiling panel 1 is obtained by heating and vacuum forming a HIPS resin sheet as shown in FIG.
It was molded in the shape of The HIPS resin used in this panel incorporates a surfactant for the purpose of preventing static charge and the like. Similarly, a hydrophilic paint may be applied to the surface. As this effect, the hydrophilicity is improved as compared with the conventional non-added product. The ceiling panel is a molded panel, which is generally a vacuum molded product, but is preferably blow molded, more preferably injection molded. On a boundary line 4 between the concave portion (arch portion) 2 and the horizontal portion 3 of the ceiling panel, a rain gutter-shaped formed body 5 composed of a hard portion and a soft portion that crosses the ceiling panel and reaches the upper end of the wall is provided. Is attached to the main body by using the hard portion 6 of FIG. At the time of cleaning, the accumulated dirt can be cleaned by turning the soft part 7 of the rain gutter into the bathroom.

In this ceiling panel, the steam generated in the bathroom forms dew on the surface of the ceiling panel. The condensed water travels along the arch and accumulates at the boundary, but drops into the rain gutter-shaped formed body, travels down the wall surface from the upper end of the wall, and is discharged to the floor-drain outlet.

[0009]

According to the present invention, the following effects are exhibited by the above configuration. In the first aspect, the surface of the ceiling panel is made hydrophilic to prevent the dew condensation water from forming water droplets, and the dew water generated on the surface is converted to water droplets and falls over the head by utilizing the entire concave shape. Instead, the water flows down the ceiling surface to the upper end of the wall, and flows down the wall to drain from the floor. In claim 2,
The ceiling panel as a whole is concave, and in a ceiling panel partially having a horizontal surface portion, a water gutter flowing from the concave portion to the boundary with the horizontal surface portion is formed by a rain gutter-shaped molded body provided in that portion. It is guided to the upper edge of the wall, and is drained from the floor to the drain through the wall. According to the third aspect, since the portion of the rain gutter-shaped formed body that is not in contact with the ceiling panel is formed of a soft material, it can be deformed, and the dirt accumulated therein can be discharged during cleaning.
