(57) [Summary] [Objective] To provide a drainage structure in a unit bath having a panel-shaped piping unit on its outer surface, which makes it easy to handle water leakage in the piping unit. [Structure] A panel-shaped piping unit (1) having a header (2) for hot water supply / water supply having a plurality of branch connection ports (3) inside is provided on an outer surface (14) of a unit bath (10). Prepared for hot water supply via this header (2)
In a unit bath (10) to which water is supplied, a waterproof pan (1) provided at a position higher than a drain port (12) of the unit bath (10) and connected to the drain port (12).
The lower end portion (6) of the piping unit (1) is surrounded by 3).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage structure of a unit bath in which a bath, a washing room, a wall, a ceiling, etc., which constitute a bathroom, are combined into a unit.

[0002]

[Prior art]

 Hot water supply / water supply to the conventional unit bath has been performed by connecting piping to the header for hot water supply / water supply located at a position away from the unit bath. However, in recent years, in order to facilitate the piping work, a panel-shaped piping unit having a header for hot water supply and water supply having a plurality of branch connection ports inside is provided on the outer surface of the unit bath, and Unit baths are being provided that supply hot water and water via the header of the. A partial sectional view of the unit bath in this case is shown in FIG. As shown in FIG. 3, regarding the drainage structure, the waterproof pan (13) connected to the drainage port (12) does not surround the piping unit (1) but simply passes through the wall (14) of the unit bath (10). Since it is configured to guide the flowing water to the drainage port (12), when there is water leakage near the header (2) for hot water supply / water supply in the panel-shaped distribution unit (1), the piping unit The leakage in (1) spreads from the lower end (6) of the piping unit (1) to the outside of the unit bath (10), and the treatment was troublesome.

[0003]

[Problems to be solved by the device]

 The present invention has been made in order to improve the above-mentioned problems, and an object thereof is to, in a unit bath equipped with a panel-shaped piping unit on the outer surface, when water leaks in the piping unit, It is to provide a drainage structure for a unit bath that can easily handle water leakage.

[0004]

[Means for Solving the Problems]

 The drainage structure of the unit bath of the present invention is equipped with a panel-shaped piping unit having a header for hot water supply and water supply having a plurality of branch connection ports inside, on the outer side surface of the unit bath, and through this header. In a unit bath where hot water is supplied, water is provided at a position higher than a drain port of the unit bath, and a lower end portion of the piping unit is surrounded by a waterproof pan that is connected to the drain port.

[0005]

[Action]

 The lower part of the piping unit is surrounded by the waterproof pan that is installed higher than the drainage port of the unit bath and is connected to the drainage port, even if there is water leakage in the panel-shaped piping unit. Leakage acts by way of the waterproof pan to the outlet of the unit bath, preventing the leakage from spreading outside the unit bath.

【Example】

 An embodiment according to the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a partial cross-sectional view showing the principle of the drainage structure of a unit bath according to the present invention, and FIG. 2 is a perspective view of a panel-shaped piping unit according to the present invention.

As shown in FIG. 2, a piping unit (1) according to an embodiment of the present invention is formed in a panel shape, and a header (2) for hot water supply / water supply is provided inside thereof. The hot water supply header (2a) is connected to the hot water supply pipe (4), the water supply header (2b) is connected to the water supply pipe (5), and the headers (2a, 2b) are provided with a plurality of branch connection ports (3.・) Is formed. The branch connection ports (3 ...) Can be connected to a pipe (not shown) in the bathroom, and hot water is supplied through the header (2).

One embodiment according to the present invention is, as shown in FIG. 1, a piping unit (1) provided with a header (2) for hot water supply / water supply having a plurality of branch connection ports (3) inside. Is provided on the outer surface (11) of the unit bath (10), and hot water is supplied through the header (2) and the branch connection port (3). Then, the lower end portion (6) of the piping unit (1) is surrounded by a waterproof pan (13) which is provided at a position higher than the drainage port (12) of the unit bath (10) and which is connected to the drainage port (12). Is formed. That is, in this embodiment, the water-proof pan (13) in the conventional drainage structure of FIG. 3 is enlarged to a position surrounding the lower end portion (6) of the piping unit (1). In FIG. 1, the waterproof pan (13) which also serves as a washing space is formed so as to surround the lower end portion (6) of the piping unit (1), but in the present invention, the waterproof pan is formed independently of the washing space. You can also do it. In FIG. 1, illustration of connection between the branch connection port (3) and piping (not shown) in the bathroom is omitted.

[0009]

[Effect of device]

 Since the drainage structure of the unit bath of the present invention is configured as described above, the leakage of water in the piping unit in the unit bath having the panel-shaped piping unit on the outer surface flows to the drain port through the waterproof pan. As a result, the effect of facilitating the treatment of water leakage can be achieved.
