2. Description of the Related Art FRP (glass fiber reinforced plastic)
Unit baths that integrate a bathtub and a washing place, etc., using such a method, are widely used in mass-produced houses such as condominiums because they can be manufactured in factories and require less labor for on-site construction. FIG. 5 is a sectional view showing a detailed configuration of a trap unit of a conventional unit bus.

[0003] A discharge port (also used as an inspection port) for discharging drainage is provided in a part of the floor in the washing room of the unit bath 51, and a metal cover 5 having a narrow groove-shaped opening is provided in this part.
2 are provided. Further, a trap 53 is provided below the metal lid 52. The trap 53 has a cylindrical inner cylinder 54 whose upper end is fixed to the periphery of the outlet 52,
An outer cylinder 55 is disposed coaxially with the inner cylinder 54 and has a closed bottom. A drain pipe 5 for guiding waste water from the bathtub to the trap 53 is provided on a side wall of the outer cylinder 55.
6, and a discharge port 57 for draining the overflow of the outer cylinder 55 to a drain pipe.

[0004] In the above configuration, the wastewater in the washing place is discharged to the inner cylinder 54 of the trap 53 through the discharge port 52, while the wastewater from the bathtub flows into the trap 53 through the drain pipe 56. The drainage in the trap 53 rises in the gap between the inner cylinder 54 and the outer cylinder 55 as it accumulates, and the outer cylinder 55
When the amount of water exceeds the upper edge, the water flows out to the outlet 57 and finally flows into a sewer pipe (not shown).

[0005] The installation dimensions of the unit bus are as follows.
Trap dimensions, reinforcement dimensions under the floor of the unit bath,
It is determined by three of the installation adjustment dimensions, and the installation dimension under the floor is generally about 180 mm. FIG. 6 shows an example of the installation dimensions of the unit bus of FIG. 5, in which the underfloor dimension of the unit bus 51 is 180 mm, the distance between the underwater bottom surface of the unit bus and the floor slab surface is 170 mm, and the threshold of the unit bus entrance 58 is shown. The distance between the surface and the floor slab surface is 270
mm. In addition, in order to reduce the distance (270 mm) between the sill surface of the entrance and exit 58 of the unit bath and the surface of the floor slab, the floor of the lavatory etc. is raised to 170 mm, and the straddle is set to 100 mm, or the floor slab of the unit bath part is used. The size is reduced by 150 to 170 mm to reduce the size of (B) in the drawing.

[0006]

However, in the above-mentioned conventional unit bath, although there is room to reduce the reinforcement size under the floor to about 120 mm by the efforts of the manufacturer, the trap size (the bottom surface of the unit bath and the surface of the floor slab). (Distance between the two) cannot be reduced to 110 mm or less. For this reason, it was not possible to meet the demand for reducing the height of the entrance and exit of the unit bus. An object of the present invention is to provide a unit bus capable of reducing the size of a trap.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing one embodiment of a unit bus according to the present invention. FIG. 2 shows II-II in FIG.
FIG. 3 is a sectional view, and FIG. 3 is a sectional view taken along line III-III in FIG.

A drain port is provided in the washing area 2 of the unit bath 1.
At the same time, a cleaning port 3 is provided to cover the drain port in a form raised above the floor level W of the washing place 2. The upper surface of the cleaning port 3 is set at the floor level V of the bathtub, and a cleaning lid 4 is provided at the center of the upper surface. Then, around the longitudinal groove-like slits 5 (except for the portion in contact with the wall) in the predetermined intervals in the horizontal direction (opening) is provided for cleaning mouth part 3, the drainage on the washing space 2 to clean mouth within 3 ( Cover with cleaning port 3
Drain side) .

As shown in FIGS. 2 and 3, the cleaning port 3 is provided at a corner of the washing place 2 in contact with the bathtub 1a so as not to disturb the user. Further, the cleaning lid 4 has a threaded structure at the connecting portion so as not to easily come off. In the floor level W of the bottom of the cleaning cover 4
The upper end of the cylindrical inner cylinder 6 is supported on the periphery of the drain port ,
The upper surface is covered with a mesh lid 7 for preventing dust from flowing into the drain pipe. Further, a case 8 is attached so as to cover the lower part of the inner cylinder 6 in close contact with the washing place 2. This case 8 is partially united.
It is provided so as to protrude from below the bus 1
