Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a drainage system for a bathroom in which a bathtub is inserted into an opening of a bathtub attachment part of a bath bed having a washing place and a bathtub attachment part.

(Prior Art) Conventionally, as described in, for example, Japanese Utility Model Publication No. 55-8163, a bathroom in which a bathtub is inserted into an opening of a bathtub attachment part of a bath bed having a washing place and a bathtub attachment part has been installed. However, in such bathrooms, in order to drain water from the bathtub and washing area, a branch pipe joint is installed in the middle of the drain pipe connected to the washing area drain, as described in the above publication, and the branch The pipe and the bathtub drain must be connected by a connecting pipe.

In such a drainage system, when repairing or inspecting the connection between the drain pipe and the connecting pipe and the branch pipe joint, remove the bathtub from the opening of the bathtub attachment part of the bath unit, and then remove the bathtub from the opening. It must be done by entering.

However, it is very cumbersome to remove and insert the bathtub one by one from the bath opening every time the connection is repaired or inspected. When installing traps, etc., cleaning them requires frequent repairs and inspections, and there has been a growing desire to eliminate this cumbersome work.

(Purpose of the invention) The present invention solves the problems of the conventional drainage equipment mentioned above, and provides a drainage equipment that facilitates the repair and inspection of bathtubs and the connections between drain pipes and connecting pipes and branch pipe joints. The purpose is to

(Structure of the invention) Hereinafter, embodiments of the invention will be described with reference to the accompanying drawings.

Reference numeral 3 denotes a bath bed, which is integrally formed and consists of a washing area 31 and a bathtub attachment part 33 having an opening 34. The bathtub 2 is inserted into the opening 34. The bathtub 2 and bath floor 3 are made of materials such as glass fiber reinforced polyester resin, enameled iron plate, stainless steel, hard vinyl chloride resin, and ABS resin.

Reference numeral 4 denotes a bathroom wall surrounding the bathroom A, which is composed of outer walls 45, 46 and partitions 47, 48, and has an inspection opening 42 fitted with a lid 43 below the outer wall 45.

The legs 36 of the bath floor 3 are placed and fixed on the base 5 of the bathroom A.

A trap 6 is attached to the drain 35 of the washing area 31 of the bath bed 3, one end of a drain pipe 7 is connected to the lower end of the trap 6, and the other end of the drain pipe 7 is connected to the outer wall 4 of the bathroom A.
It penetrates the lower part of the inspection port 42 of No. 5 and extends outward, and is connected to a sewer pipe or the like for drainage.

Inspection port 42 inside the outer wall 45 of the drain pipe 7
A branch pipe joint 71 is provided near.

8 is a connecting pipe, one end of which is connected to the drain port 22 at the bottom of the bathtub 2, the other end of which is extended to the vicinity of the inspection port 42 and connected to another connecting pipe 9; It is connected to the branch pipe 711 of the branch pipe joint 71. The other connecting pipe 9 is constructed by connecting a bent pipe 91 and a trap 92 with a cap nut 93, as shown in an enlarged view in FIG. one end of the trap 92 is connected to the branch pipe 711 and the joint 1.
1.

Incidentally, the connecting pipe may be composed of a single flexible pipe instead of being composed of a plurality of pipes and joints as in the illustrated embodiment.

To assemble the drainage system of the present invention constructed as described above, first, the drain pipe 7 is installed on the foundation of the bathroom A, as shown in FIG. At this time, the branch pipe joint 71 is provided near the inspection port 42 in the middle of the drain pipe 7. Next, the bath bed 3 is placed and fixed on the base 5 so that the bathtub attachment part 33 is located on the inspection port 42 side, and the trap 6 is inserted into the bath bed 3 through the opening 34 and connected to the drain port 35 of the washing area 31. Attach the drain port 2 to the bathtub 2 and connect it to the drain pipe 7.
Connect the connecting tube 8 to the connecting tube 2, and temporarily attach the connecting tube 8 to the tip with the tip of the connecting tube 8 facing the inspection port 42.
The bathtub 2 to which the connecting pipe 8 is attached in this manner is inserted and attached to the opening 34 of the bath bed 3.

Connection of the connecting pipes 8 and 9 and connection of the connecting pipe 9 and the branch pipe of the branch pipe joint 71 are performed from outside the bathroom A through the inspection port 42. That is, one end of the trap 92 of the connecting pipe 9 is connected to the branch pipe 711 of the branch pipe joint 71, the other end of the trap 92 is connected to one end of the bent pipe 91 with a cap nut 93, and the other end of the bent pipe 91 is connected to the branch pipe 711 of the branch pipe joint 71. A drainage system is assembled by connecting to the connecting pipe 8 attached below the pipe 2.

(Effects of the invention) In this invention, the branch pipe of the branch pipe joint installed near the inspection port in the middle of the drain pipe connected to the drain of the washing area of the bathtub and the drain of the bathtub are connected by a connecting pipe. This makes it easy to repair and inspect the connections between drain pipes, connecting pipes, and branch pipe fittings through the inspection port, eliminating the hassle of removing and inserting the bathtub one by one each time an inspection is done in the past. No additional work is required.

Further, when a trap is provided in the connecting pipe as in the illustrated embodiment, the trap can be conveniently cleaned from the inspection port.
