DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub with an illumination function that can illuminate the vicinity of a spout while avoiding the risk of electric shock or the like.

[0002]

2. Description of the Related Art Heretofore, there has been provided an apparatus in which water supplied from a water outlet is supplied like a waterfall and supplied into a bathtub body for the purpose of improving the atmosphere during bathing. The applicant of the present application assumed that water flowing out like a waterfall can be illuminated by an optical fiber cable, as shown in FIG.
No. 277375 has been filed. In this device, the tip of an optical fiber cable 4 led out of a light source box 3 outside the bathroom is arranged below the water outlet 2 as shown in FIG. 9, and the optical fiber cable 4 illuminates the vicinity of the water outlet 2. Like that.

[0003]

However, according to the above-mentioned Japanese Patent Application No. 2-277375, the illumination from the optical fiber cable 4 is performed as shown in FIG. Illuminates the front of the bathtub 1 as shown in FIG. 11, and the bather looks straight at the time of bathing in the bathtub main body 1 as shown in FIG. When the amount of water is reduced, water falls to the end of the optical fiber cable 4 as shown in FIG. 12, and the water always travels along the optical fiber cable 4 to the waterproof processing section a as shown in FIG. There is a problem that the water is flooded, which is not preferable in terms of waterproofing.

An object of the present invention is to provide a bathtub with a lighting function capable of preventing dazzling when bathing and improving waterproof performance.

[0005]

According to the present invention, in order to achieve the above object, a water outlet 2 for discharging water like a waterfall toward the inside of the bathtub body 1 is provided on the flange 1a of the bathtub body 1, and the outside of the bathroom is provided. With the front end of the optical fiber cable 4 led out of the light source box 3 disposed below the water outlet 2 and a reflection drain plate 5 provided between the water outlet 2 and the front end of the optical fiber cable 4 It is.

[0006]

The lighting from the optical fiber cable 4 is bent by the reflection drain plate 5, so that a person taking a bath in the bathtub body 1 can perform the lighting while avoiding looking directly at the lighting. When the water discharge from the water discharge port 2 is stopped or when the water discharge amount from the water discharge port 2 is reduced, the water that falls downward is drained by the reflection water drain plate 5 and does not travel down the optical fiber cable 4. .

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. The bathtub includes a bathtub body 1 and a flange 1a provided on the outer periphery of an upper end portion of the bathtub body 1. A water outlet cover 6 is provided on the flange 1a located in the short side direction of the bathtub body 1, and the water outlet 2 and the tip of the optical fiber cable 4 are housed in the water outlet cover 6. As shown in FIG. 3, the front end of the optical fiber cable 4 is connected to the optical fiber unit 7, and the optical fiber unit 7 is attached to the lower surface side of the water discharge port 2 and housed in a receiving box 8 provided on the flange 1a. The tip of the optical fiber cable 4 is located below the water outlet 2. Optical fiber unit 7
Is provided with a reflective draining plate 5 whose tip is bent obliquely downward. The reflective drainer 5 is provided between the water outlet 2 and the tip of the optical fiber cable 4 in a state where the water outlet 2 and the optical fiber unit 7 are connected. The plate 5 is arranged. The water supply pipe 9 up to the water outlet 2 is led out by a pump arranged in the storage space 10 below the flange 1a.
The pump is connected to a circulating pipe extending from the bathtub body 1 and a hot water supply pipe to which hot water is supplied and a water supply pipe to which city water is supplied. Is designed so that hot water or circulating water sucked up from the bathtub is discharged like a waterfall.
The inner wall of the bathtub body 1 is provided with a jet water jet port 11 for jetting water into the bathtub main body 1 vigorously, and a jet port 12 for jetting water containing fine air bubbles containing fine air bubbles in the bathtub main body 1. Is provided. Reference numeral 13 denotes a suction port for sucking hot water in the bathtub body 1.

A light source box 3 is installed on a ceiling panel 14 constituting a bathroom, as shown in FIG.
An optical fiber cable 4 is led out of the light source box 3, and the leading end of the optical fiber cable 4 is disposed below the water outlet 2. As shown in FIG. 6, the light source box 3 is configured such that a lamp 15, a filter 16, a transformer 17, a lens 18, and a filter rotation motor 19 are housed and arranged in a housing box 3a. Is the storage box 3a by the holder 20
The cooling fan 2 for cooling the inside of the storage box 3a is provided at the other end of the storage box 3a.
1 is provided.

[0009] The light from the lamp 15 is
The water is sent to the end of the optical fiber cable 4 through the filter 16 and the water, and the water flowing out of the water outlet 3 and the water outlet 3 can be illuminated from behind by the optical fiber cable 4. Here, the illumination from the front end of the optical fiber cable 4 is bent by the reflection drain plate 5 as shown in FIG. 1 and is applied to a portion where the water discharged from the water discharge port 2 falls into the bathtub body 1. And the lighting effect has been improved,
By being bent downward, it is possible to avoid that the bathing person is directly illuminated with the lighting, and to prevent the bather from looking directly at the lighting and becoming dazzled.
When the water discharge from the water discharge port 2 is stopped or when the amount of water discharge is reduced, the water discharged from the water discharge port 2 will flow downward, but as shown in FIG. The water is drained by the plate 5 and falls into the bathtub main body 1 without falling to the tip of the optical fiber cable 4, thereby preventing water from flowing into the optical fiber cable 4 and adversely affecting the optical fiber cable 4.

However, the atmosphere during bathing can be improved by illuminating the water flowing out of the water outlet 3 near the water discharge port 3 during bathing, and the light source box 3 can be illuminated outside the bathroom. Since it is performed by the installed optical fiber cable 4, the water outlet 3
It is possible to illuminate the bathroom without fear of electric shock even if the lighting is done near the place, but also to improve the lighting effect and the waterproof effect, without making the bathing objects dazzling It can be illuminated.

In the illustrated embodiment, the reflection drainer 5 is provided integrally with the optical fiber unit 7. However, the present invention is not limited to this. Water mouth 2 and optical fiber cable 4
It may be adapted to be mounted between the front end of the head.

[0012]

As described above, according to the present invention, a water outlet for discharging water like a waterfall toward the inside of the bathtub body is provided on the flange of the bathtub body, and an optical fiber cable led out from a light source box disposed outside the bathroom. The bottom of the water outlet is exposed below the water outlet, and the reflection water draining plate is provided between the water outlet and the optical fiber cable, so that the reflection water draining plate bends the illumination from the optical fiber cable to take a bath in the bathtub body. Water that can be illuminated while avoiding the person who is gazing directly at the lighting, and water that falls downward when stopping the water discharge from the water discharge port or when reducing the amount of water discharge from the water discharge port Is to be drained by the reflective drain board, which can prevent it from traveling along the optical fiber cable and entering the installation part of the optical fiber cable. That.
