Description

[Detailed Description of the Invention] The present invention relates to an improvement in a structure for attaching a circulating metal fitting for a bath water circulation pipe and / or a pouring pipe fixed to a side face of a bathtub with a washing place.

(Prior art) Recently, a method in which hot water is guided to a water heater to naturally circulate high-temperature hot water to the bathtub by a reciprocating pipe, or bath water is guided to a water heater and forced between the bathtub and the water heater by a circulation pump The method of circulating in (hereinafter referred to as "forced circulation method") is widely used.

In this forced circulation system, the reciprocating pipe for bath water and the pipe for pouring water are connected to one circulation fitting, and the circulation fitting is fixed to a through hole provided on the side surface of the bath via packing.

(Problems to be solved by the invention) The circulating metal fittings and the bath-side through-holes are structured to ensure watertightness by packing, but there are irregularities on the back surface of the bathtub or insufficient tightening of the circulating metal fittings. do it,
Water may leak from the connection part of the through hole.

That is, in the bathtub with a washbasin, there is no waterproof floor below the back of the bathtub, so in the event of water leak, the leaked water will flow to the building floor of the bathroom and will cause a large amount of damage to the lower floor room. There is a problem that causes various damages. Therefore, as a countermeasure against water leakage, as shown in Japanese Utility Model Publication No. 56-36397, a method has been adopted in which a water leakage tray made of synthetic resin or the like is attached to the backside of the bath under the circulation fitting. However, there is a problem that the water leakage receiving tray is manufactured in various types according to the shape of the bathtub, and the mounting work is complicated, so that it becomes expensive.

The present invention has been made in view of the above problems, and an object thereof is to provide an inexpensive structure for mounting a bathtub circulation fitting that does not damage the lower floor even if water leaks. Is.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 3 corresponding to the embodiments.
Bathtub water circulation pipes (8) and (9) fixed to the side surface of the bathtub (2) of the bathtub with a washroom (1) and / or a pipe for pouring water (1)
0) In the mounting structure of the circulation fitting (4), the circulation fitting (4) is connected to the pipes (8), (9) and / or (10).
(1) with an inner diameter equal to or slightly smaller than the outer diameter of
4) is covered with a circulating metal fitting cover (11) integrally formed, and the cover (11) is tightly fixed to the side surface of the bathtub (2), and the pipes for circulating water in the bathtub (8), (9) and / or A technical means is adopted in which a pipe (10) for hot water is inserted into the tubular portion (14) and the bottom of the cover (11) and a drain discharger (17) provided on the wall surface of the washing place are connected by a pipe (16). There is.

(Operation) According to the present invention, by the above means, even if water leaks from the attachment part between the circulation fitting and the side surface of the bath, the leaked water flows into the circulation fitting cover and is discharged to the washing place through the piping.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 is a bathtub with a washroom, in which a bathtub 2 is provided on one side and a washroom 3 is provided on the other side, which are integrally formed of synthetic resin such as FRP.
Reference numeral 4 fixes pipes 8 and 9 for circulating bath water between the bathtub 2 and a water heater (not shown), and a pouring pipe 10 for pouring water from the water heater to the bathtub 2. It is a circulation fitting,
The metal fitting 4 is fastened to the rear surface of the bathtub 2 by a tightening ring 6 from the bathtub 2 side through a packing 7 in a through hole on the side surface of the bathtub 2.

Reference numeral 12 denotes a cylindrical cover body having a flange portion on the periphery and formed of a hard synthetic resin. The cover body 12 is fixed in a watertight manner around the circulation metal fitting 4 fixed to the back surface of the bathtub. . Reference numeral 13 denotes a bowl-shaped cover made of rubber or soft plastic having elasticity, and the cover 13 integrally covers the circulation metal fitting 4 and is fixed to the cover body 12 by a tightening metal fitting 15. That is, the circulation fitting cover used in the present invention is composed of the cover body 12 and the cover 13.

A plurality of cylinders 14 are integrally formed on the back surface of the cover 13, and bathtub water circulation pipes 8 and 9 and a pouring pipe 10 are inserted into the cylinders 14. The inner diameter of the tubular portion 14 is formed to be the same as or slightly smaller than the outer diameter of the pipes 8, 9 and 10, and the tubular portion 14 uses its elasticity to be in close contact with the pipes 8, 9 and 10. Is configured to be.

Further, a flexible pipe 16 made of soft plastic is connected to the bottom of the cover 13, and the other end of the flexible pipe 16 is connected to a drain discharge fitting 17 fixed to the wall surface of the washing place. A cap 18 is attached to the surface of the drain discharge fitting 17 on the washing side so that foreign matter such as hair does not enter the pipe.

(Effect of the Invention) In the present invention, the circulation fitting is covered with a circulation fitting cover integrally formed with a tubular portion having an inner diameter equal to or slightly smaller than the outer diameter of the pipe, and the cover is closely fixed to the side surface of the bath. In addition, the bath water circulation pipe and / or the pouring pipe is inserted into the tubular portion, and the cover bottom portion and the drain discharge fitting provided on the wall surface of the washing place are connected by the pipe, so that the following effects are obtained. It is a thing.

1) Even if there is water leakage between the circulation fittings and the surroundings of the through hole on the side of the bathtub, the water that flows out will be discharged to the washroom, so it will not damage the outside of the bathroom or the room on the lower floor.

2) Since the circulation fitting cover is attached to the circulation fitting,
Since the same parts can be used for baths of various shapes and the mounting work is extremely easy, it can be provided at low cost.
