Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the installation structure of a heating bath equipped with a heating coil, and in particular, the arrangement method of connecting piping to the heating coil and the location where the handle is installed. This article relates to an improved heating bath installation structure.

[Prior Art] As a heater for heating water or hot water in a bathtub, a heater that employs a heating coil through which a heating medium such as high-temperature water is passed is known.

A conventional example of this type will be explained with reference to the drawings.

In FIG. 5, a bathtub (bath) 1 is provided inside the unit, and an inner wall surface 1 on the foot side of the bathtub 1 is provided.
A heating coil 2 is provided along the line a. The heating coil 2 is made of, for example, a copper pipe bent into a meandering shape, and is connected to a hot water supply source (not shown) via a hot water supply pipe 3 and a hot water return pipe 4. A midway portion of the pipe 3 is drawn into the handrail portion 1b of the bathtub 1, and a hot water supply valve 7 having a handle 5 is provided in this portion to supply hot water to the heating coil 2. As shown in FIGS. 4 and 6, a cover 6 made of FRP or the like is placed over the heating coil 2, and the water (or hot water) in the bathtub 1 circulates between the lower side of the cover 6 and the bathtub bottom 1c. After entering the cover 6 and being heated by contacting the heating coil 2, it is extracted out of the cover through the opening 6a.

[Problems to be solved by the invention] In the above conventional example, water leaks from the through hole where the operating shaft of the hot water supply valve 7 passes through the wall of the handrail 7, the joint part of the hot water supply valve 7, etc. As shown in Fig. 7, there was a risk that the floor surface 8 would become wet and water would leak downstairs.

Furthermore, in the above-mentioned conventional heating bath installation structure, the pipe 3 is drawn into the handrail portion 1b, which results in a long pipe length, which is inconvenient for pipe construction. In addition, inspection and repair of valve 7 was difficult.

[Means for solving the problem] The heating bath installation structure of the present invention is such that the heating coil piping is raised upward and then bent horizontally above the upper edge of the bathtub, and then installed outside the unit. At the same time, a hot water supply valve is provided in the interior of the unit in the middle of this piping, and an operating handle for the hot water supply valve is provided inside the unit interior.

[Function] In the heating bath installation structure of the present invention, even if water leaks from the hot water supply valve, the leaked water will fall into the unit interior (for example, inside the bathtub) and will not flow out to the outside of the unit interior.

Further, no extra piping is required, and inspection and repair of the hot water valve becomes easy.

[Example] Examples will be described below with reference to the drawings.

Fig. 1 is a perspective view showing the installation structure of a heating bath according to an embodiment of the present invention, Fig. 2 is a sectional view of the same,
FIG. 3 is an enlarged sectional view of the portion shown in FIG. 2. In FIGS. 1 to 3, the same parts as in FIGS. 4 to 6 are designated by the same reference numerals.

In the installation structure of the heating bath according to this embodiment, the hot water supply pipe 3 and the hot water return pipe 4 (however, 4 is not shown) of the heating coil 2 are raised vertically upward from the heating coil 2, and then It is bent horizontally above the upper edge and extracted outside the unit room. A handle 5 is attached to a part of the pipe 3 inside the unit chamber (in this embodiment, the connecting part between the vertical part and the horizontal part).
A hot water supply valve 7 having a hot water supply valve 7 is installed. cover 6
has a through hole 6b for exposing the handle 5 at the top, so that the handle 5 can be easily operated from either inside the bathtub 1 or from the washing area 9. Note that the lower part of the cover 6 is connected to the bathtub 1 via a cover fixing fitting 10 made of stainless steel or the like.
The upper part of the cover 6 is locked by inserting an L-shaped metal fitting 11 fixed to the cover 6 into a receiving metal fitting 12 fixed to the edge of the waterproof pan. Therefore, the cover 6 can be easily removed by simply removing the screws 13 that fasten the cover 6 to the metal fitting 10, and the valve 7 and the heating coil 2 can be inspected, repaired, cleaned, etc. ing. Further, the valve 7 is supported by a waterproof pan via a support fitting 14, and is configured so as not to wobble even when the handle 5 is gripped.

In the heating bath installation structure having such a configuration, even if water leaks from the valve 7, there is no risk that this water will fall into the bathtub 1 and wet the floor surface on the lower side of the unit room. Also, the piping can be short.

In the above embodiment, the hot water supply valve 7 is provided in the piping 3 on the hot water supply side, but it may be provided in the piping on the return side. Further, in order to expose the handle 5, a notch may be used instead of a through hole. Furthermore, in the present invention, the arrangement method of the pipes 3 and 4 may be changed in various ways without departing from the spirit of the present invention, such as bending the pipes 3 and 4 in the horizontal direction once or multiple times at the rising part on the inside of the unit. It is possible.

[Effects] As described above, in the present invention, even if water leaks from the hot water valve, water leakage to the downstairs is completely prevented.

In addition, the piping is short and assembly is easy. Furthermore, in the present invention, since the handle and the hot water supply valve are located inside the unit, inspection and repair thereof can be carried out extremely easily.
