2. Description of the Related Art Conventionally, public toilets have the image of being dark and dirty. However, due to various conditions such as having a plurality of toilet booths, being divided into men and women, and having to block external visibility. It is difficult to efficiently perform ventilation and lighting. In general public toilets, ventilation holes are provided almost at the center of the roof of the building.In this case, however, odor accumulation tends to be formed in the corners of the room, especially in the toilet cubicle booth in the corner, where the odor is muffled and dark. is there. In order to solve this, it is conceivable to provide a plurality of lighting windows and vents for each toilet bowl booth, to install a large forced ventilation device, to install a large number of lighting fixtures, etc., but all of them increase costs.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances.
It is an object of the present invention to provide a new public toilet that can efficiently perform indoor ventilation and lighting by using a single lighting unit.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a lighting part with a ventilation opening on a roof of a skeleton, and secures a ventilation space between the roof and a roof of the skeleton in a room. A suspended ceiling is provided, and a gap is formed between the suspended ceiling and the indoor wall surface to communicate with the ventilation port through the ventilation space, and the suspended ceiling allows sunlight supplied from a lighting unit to enter the room. It is characterized by being formed of a light transmissive member that can be supplied.

In such a configuration, the sunlight taken in from the daylighting section passes through the suspended ceiling and is supplied to almost the entire area of the room, and the solar heat warms the air in the room, generating an upward airflow, and the indoor air is generated. The muffled odor rises along the interior wall and passes through the gap between the suspended ceiling and the interior wall,
After passing through the ventilation space behind the suspended ceiling, it is naturally discharged from the ventilation opening of the lighting section. Therefore, ventilation and lighting can be efficiently performed over the entire area of the room.

The gap provided between the suspended ceiling and the indoor wall surface is
Preferably, it is formed along the indoor wall surface. In this case, the odor that rises along the indoor wall surface can be discharged more efficiently.

As a specific configuration of the suspended ceiling, there is a suspended ceiling made of a translucent acrylic plate. In this case, in addition to the above-described operation, a soft light can be supplied to the entire room, and a high-class atmosphere different from the case where a lighting fixture is used is created.

[0008] The vent can also be connected to forced ventilation means, in which case the ventilation function is of course further improved.

In the public toilet according to the present invention, a partition panel is erected on the back or side of the toilet in the toilet bowl booth to form an exhaust space separated from the toilet space on the back side of the partition panel. A suction port for communicating the exhaust space and the toilet space is provided below the exhaust space, and the exhaust space includes a mode in which the exhaust space is connected to a forced exhaust path.

In this case, since forced exhaust is performed in the vicinity of the location where the odor is generated, the ventilation function is greatly improved.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view of a public toilet with a part omitted, and FIG. 2 is a sectional view taken along the line (X)-(X). In the figure, 1 shows a toilet body, for example, on a concrete foundation floor. , A skeleton wall 2 formed by connecting a plurality of GRC composite panels and the like, and a skeleton roof 3 formed by connecting a plurality of GRC composite panels and the like and applying sheet waterproofing. A lighting part 5 having a ventilation opening 4 is formed in the frame roof part 3.

The daylighting section 5 has a daylighting hole 5a which is also used as a through hole at a predetermined location on the skeleton roof section 3, usually at a location substantially at the center of the room (in the toilet) 6, and surrounds the daylighting hole 5a. Is formed, and the upper surface thereof is further covered with a dome-shaped top plate 5c made of a transparent or translucent member.

In the room 6, a required number of toilet bowl booths 7 are formed, and a required number of urinals, washbasins, night lighting fixtures and the like (not shown) are installed. In the room 6, a suspended ceiling 9 is suspended by a predetermined number of suspended members 8, and the frame roof 3 and the suspended ceiling 9 are suspended.
A ventilation space 10 is formed therebetween. Considering the maintenance of the lighting fixtures and the like arranged behind the suspended ceiling, the suspended ceiling 9 is attached to the suspended member 8 or the suspended ceiling 9 and the suspended member 8 are attached to the frame roof 3 using, for example, a magnet or a magnetic tape. On the other hand, it is preferable to attach it detachably. A gap 11 is formed between the outer edge 9a of the suspended ceiling 9 and the indoor wall surface 2a to communicate with the ventilation port 4 via the ventilation space 8 and the lighting hole 5a.

The suspended ceiling 9 is formed of a light transmitting member capable of supplying the sunlight supplied from the daylighting section 5 to the room. In this example, to supply soft light to the whole room 6,
A suspended ceiling 9 made of a translucent acrylic plate is used to create a luxurious atmosphere different from lighting equipment.

According to the above configuration, the sunlight taken in from the daylighting section 5 passes through the suspended ceiling 9 and is supplied to almost the entire area of the room 6 to create a luxurious atmosphere different from that of the lighting equipment. The air in the room 6 is heated by the solar heat, and an updraft (indicated by arrows in FIGS. 1 and 2) is generated.
The muffled odor rises along the indoor wall surface 2a, passes through the gap 11 between the suspended ceiling 9 and the indoor wall surface 2a, and passes through the suspended ceiling 9
After passing through the ventilation space 10 on the back side, the air is naturally discharged from the ventilation port 4 of the daylighting unit 5. Therefore, ventilation and lighting can be efficiently performed over the entire area of the room.

In this embodiment, the natural ventilation structure in which the ventilation opening 4 is formed by the gull provided in the daylighting section 5 is illustrated, but a forced ventilation means (not shown) such as a fan is provided in the ventilation space 10 or on the roof 3 of the frame. Can be provided to communicate with the ventilation port 4. In this case, the odor rises along the indoor wall surface 2a even in an environment where an updraft is unlikely to be generated by the forced ventilation means, so that the odor can be efficiently exhausted from the ventilation port 4 and is suitable for use in a cold region or at night. .

FIG. 3 shows a toilet bowl booth. In the toilet booth, a partition panel 22 is erected at a corner inside the booth that is obliquely rearward of the toilet 21, and an exhaust space 24 that is separated from the toilet space 23 is formed on the back side of the partition panel 22. A suction port 25 for communicating the exhaust space 24 and the toilet space 23 is provided below the partition panel 22, and the upper surface of the exhaust space 24 is covered with a top plate 26 and provided with a forced exhaust means 27 such as a fan. By communicating with the path 28, forced exhaust can be performed in the vicinity of the place where the odor is generated.

In the toilet bowl booth shown in FIG. 4, a partition panel 22 'is erected behind a toilet 21 and the partition panel 2'
Exhaust space 24 is formed on the back side of 2 ′, and the other configuration is the same as that shown in FIG. 3, so the same reference numerals are given in the figure, and duplicate description will be omitted. Also in this example, forced exhaust can be performed in the vicinity of the location where the odor is generated. In addition, a partition panel may be erected on the side of the toilet, in other words, a toilet panel and an exhaust space are partitioned by a partition panel having a suction port below, and forced exhaust is performed near a location where odor is generated. What should I do?

The toilet bowl booth 7 shown in FIG.
Although not shown in FIG. 4 and the like, the toilet 7a is simply installed in the booth, but instead of the toilet booth 7, the toilet booth shown in FIGS. 3 and 4 can be adopted. The synergistic effect of discharging the odor from the gap 11 along the indoor wall surface 2a and performing forced exhaust in the vicinity of the odor generation location greatly improves the ventilation function.

[0020]

As described above, according to the present invention, the sunlight from the daylighting section is supplied to the entire room through the suspended ceiling, and the odor and the like are raised along the indoor wall surface by the rising airflow generated by the solar heat. Because it was configured to naturally discharge from the ventilation opening through the gap between the suspended ceiling and the indoor wall surface, the ventilation space behind the suspended ceiling, the minimum required number of lighting parts and ventilation holes,
As a public toilet capable of efficiently performing ventilation and lighting throughout the entire room, it can be suitably provided in facilities such as parks, expressways, and sports fields. In addition, since the above-described effects can be obtained without providing a separate forced exhaust means or providing a large number of lighting windows and vents, construction costs and maintenance costs can be reduced. It is also possible to separately provide a forced exhaust means, and in this case, it is suitable for use in a cold region or at night. Also, if the suspended ceiling is formed of a translucent acrylic plate, it is possible to supply soft light to the whole room, and to create a high-class atmosphere different from that of lighting equipment, and to achieve many effects.
