Description

Detailed Description of the Invention "Industrial Application Field" The present invention relates to a steel frame constructed in a substantially box shape, and a base plate, wall, and ceiling made of FRP, which is incorporated inside the frame. The present invention relates to the structure of the ceiling in a bathroom unit including a bathroom structure molded from a resin such as the above.

``Prior Art'' In single-family prefabricated houses and the like, planned prefabricated houses called ``freestyle'' and the like are already being supplied in place of uniform and standardized houses. Along with this, various variations of exterior and interior designs have been developed to meet diverse needs, and in particular, bathrooms have expanded beyond the function of simply bathing.
It is considered as a single private room and is required to have various functions inside.

By the way, in recent years, while it has become desirable to create a place or environment in the home to release stress, there are many cases where it is not possible to avoid one room due to the site, and in such cases, the bathroom can be used as a relaxing space. Attempts are being made to use it as a place for

Examples of such attempts include installing bubble bathtubs and body showers with excellent pine surge effects in bathrooms, or installing speakers, televisions, etc. in bathrooms to play background music.
These structures simply change the bathtub of the bathroom unit to a bubble bath or have built-in speakers without changing the layout of the conventional bathroom unit, so they can be used as a place to create an environment to relax the mind and body. The reality was that it was not sufficient.

In addition, in recent years, in order to improve ventilation inside the bathroom,
In addition to installing ventilation fans in the ceilings of bathroom structures, attempts are being made to install body dryers to dry the body after taking a bath or to use the bathroom as a drying room.

However, conventionally, a bathroom structure installed in a bathroom unit that constitutes a bathtub inside a house has a basic configuration in which, for example, a bathtub, a washbasin, and a toilet bowl are arranged in parallel in sequence along the side wall of the bathroom. Because of this, bubble bathtubs and B
Even if GM speakers were built in, it would not be sufficient to create an environment for relaxing the mind and body, and since the bathroom was not partitioned, it would be difficult to incorporate a body dryer. There was a problem that it was difficult to

Therefore, as a result of intensive research to solve these problems, the present inventors installed a tower with a door that constitutes a changing room in the center of the bathroom structure, and built a bathroom and washroom around this tower. If you separate the changing room and open the outlet of the body dryer in the changing room, you can dry your body with the body dryer in the changing room that is separated from the bathroom. We came up with the idea that it would be easier to create a space that relaxes the mind and body.

``Problem to be solved by the invention'' However, the ventilation fans and body dryers installed in bathroom units with such functions are relatively large, so it is difficult to assemble the ventilation fan into the ceiling of the unit as in the past. In particular, if a structure in which large equipment is mounted on the ceiling of the unit is used, there are problems such as maintenance becomes difficult.

The present invention has been proposed in view of the above-mentioned circumstances, and its purpose is to provide a ceiling in a bathroom unit that can effectively and appropriately assemble large electrical equipment such as ventilation fans and body dryers, and that can also be easily maintained. The aim is to provide a structure for the department.

``Means for Solving the Problems'' In order to achieve the above object, the present invention provides a medium constructed of steel frames into a substantially box shape, and a medium that is incorporated inside the frame and is attached to the bottom plate, walls, and ceiling. and a bathroom structure molded from resin such as Fr'LP, respectively.
Inside the bathroom structure, a washroom and a bathroom are provided on the left and right sides of the laundry room, respectively, and in the front of the laundry room, there is a changing room that partitions the bathroom and the washroom and communicates with the laundry room. It is a bathroom unit in which a cylindrical tower is installed, and a door is provided along the outside of the tower to open and close the entrances to the bathroom and washroom, respectively. A body dryer and a ventilation fan are suspended from the ceiling of the building frame at a position facing the ceiling of the laundry room through the joists of the building body, and an air outlet of the body dryer and a ventilation fan are mounted on the ceiling board of the changing room. The ventilation openings are respectively opened, and the ceiling plate is removably attached to the ceiling of the bathroom structure.

``Function'' In the ceiling structure of the bathroom unit with this configuration, large equipment such as ventilation fans and body dryers are suspended from the ceiling of the steel frame. In addition, by removing the ceiling panel that forms the ceiling of the changing room, you can expose the ventilation fan and body dryer to the open area of the ceiling panel. We can also maintain equipment such as ventilation fans and body dryers.
