Description

[Detailed Description of the Invention] This invention relates to an improvement of a hot water supply device for a bathtub that supplies hot water to a bathtub.

Hot water supply (including water supply) to bathtubs in unit baths and other bathrooms is done by attaching various faucet fittings to the bathroom wall or to the upper edge of the bathtub, but the faucet part protrudes toward the bathtub side. Therefore, when hot water is heated, there is a risk of getting burned if you touch the faucet, and the protruding faucet gets in the way when taking a bath. Furthermore, there is the inconvenience of not being able to supply hot or cold water with the bath lid closed, and from a design standpoint, the faucet fittings commonly used in the past are not suitable for Japanese-style bathrooms.

Therefore, this idea was devised in view of the above-mentioned circumstances, and as a means of supplying hot water to the bathtub, the water spout such as a faucet is not exposed indoors, and the area around the bathtub is made clear. The object of the present invention is to provide a hot water supply device for a bathtub that improves the problems described above.

Next, this invention will be explained in detail with reference to illustrated embodiments.

In the illustrated embodiment, the invention is applied to a water heater for an FRP bathtub in a unit bath, but this bathtub is also intended for bathtubs in general bathrooms, and bathtubs can be made of FRP, etc.
This includes molded bathtubs such as stainless steel and enamel bathtubs.

In the illustrated embodiment, the bathtub body 1 has rising walls 11 on two sides that receive the side walls 2 of the bathroom rising integrally from the upper edge 12, and one rising wall 11 has a spout 13 in the center thereof. It runs through in the form of a long groove. Upper edge 12 below this spout portion 13
A groove 14 having a bottom width longer than the length of the spout 13 is formed in the part, and the bottom of the groove 14 is depressed one step below the upper edge 12 and has a slight water gradient to the side wall 15 of the bathtub body 1. The boundary edge 14a is chamfered.

A hot water supply pipe 3 is connected to the water spout portion 13 from the outdoor side. In the hot water supply pipe 3, hot water mixed at an appropriate temperature by a mixing valve or other hot water mixing device (not shown) is supplied through an on/off valve (not shown).
A reservoir 4 made of corrosion-resistant metal, heat-resistant plastic, etc. is provided at the downstream end of the hot water supply pipe 3, and the hot water is supplied through the reservoir 4 to the hot water supply pipe 3. and the spout portion 13 are connected in a watertight manner. In the illustrated example, the reservoir 4 has a box shape, and has a connection port 41 with the hot water supply pipe 3.
and an opening 42 communicating with the spout 13,
An integrally provided mounting plate 43 is connected to the spout portion 13 via a gasket 44. This connection structure is the second
As shown in FIG. 3, the shielding plate 5 that shields the water outlet 13 is applied from the indoor side to the water outlet 13 leaving a water passage gap S, and the mounting bolts 51 and 5 provided on the shielding plate 5 are
1 is a bolt hole 13a provided on the outside of the spout portion 13.
It is connected to the mounting hole 43a of the mounting plate 43 of the reservoir section 4 by tightening a nut. (In the figure, 52 indicates a washer, and 53 indicates a gasket.) The shielding plate 5 described above is made of a stainless steel plate or other metal plate, and its cross section is bent into a dogleg shape to prevent the water flow from the water spout 13. The water spout 13 and the groove 14 are shielded from the indoor (bathtub) side to prevent the water spout 13 from being exposed to the indoor side. There is a crank-shaped water passage gap S between
is formed so that the hot water supply water flows through the water passage gap S in a gentle flow.

As described above, when the hot water supply pipe 3 is connected to the spout 13 provided on the rising wall 11 of the bathtub body 1 via the reservoir 4 and hot water is supplied through the hot water supply pipe 3, the water is supplied to the hot water supply pipe 3. The hot water is temporarily pooled in the reservoir 4, the water force is weakened, and then passes from the reservoir 4 through the spout 13, flows through the crank-shaped water passage gap S formed by the shielding plate 5, and flows into the groove. 14, it flows down into the premises of the bathtub body 1 in a waterfall-like state, and hot water is supplied to the bathtub (the same goes for water supply).

In the embodiment described above, the hot water supply pipe 3 is connected to the water spout 13 via the reservoir 4, and the reservoir 4 is formed in a box shape. , a planar fan-shaped or flat-shaped joint fitting may be used, and the bottom of the reservoir 4 is connected to the spout 13
When the hot water supply is stopped, a water gradient is applied to the reservoir section 4.
It is designed to prevent hot water from remaining inside. Also,
Both sides and the bottom of the groove 14 of the bathtub body 1 may be covered with a decorative plate (not shown) made of a corrosion-resistant metal plate such as a stainless steel plate.

As described above, according to this invention, a water spout is provided in the rising wall formed along the upper edge of the bathtub body, and a groove is formed in a part of the upper edge below the water spout. A hot water supply pipe is connected to the spout, and the spout and the groove are configured as a hot water spout into the tank, so the faucet does not protrude around the bathtub like in conventional structures. Hot water is supplied to the bathtub from a groove in the bathtub body, along the side wall of the bathtub, and flows into the bathtub.There is no risk of getting burned by touching the protruding faucet, and there is no risk of getting in the way while taking a bath, or creating a negative atmosphere in the interior design. This eliminates the faucet part that does not fit the bathtub, making it possible to organize the area around the bathtub neatly.Furthermore, it is possible to supply hot water even when the bathtub lid is closed, which prevents the water temperature from dropping during hot water supply. It has excellent functions and effects, such as preventing steam from rising in the bathroom and eliminating noise from hot water supply.
