Abstract

PURPOSE:To safely produce comfort in combination of water and light by providing a light transmitting plate 2 molded into a bathtub shape as a bathtub body and illumination boxes disposed to sandwich both opposed end edges of the light transmitting plate as the bathtub body and have light sources built therein. CONSTITUTION:A bathtub 1 is composed of a light transmitting plate 2 molded into a bathtub-like form as a bathtub body and illumination boxes 3 disposed to sandwich two opposed end edges of the light transmitting plate 2. The light of light sources in the illumination boxes 3 is conducted to the light transmitting plate 2 to make the surface luminescent. Thus, comfort in combination of light and water can be produced while the preservation and inspection are facilitated and the water-proof property and safety are improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub.

[0002]

2. Description of the Related Art Bathing has the purpose of washing the body and relieving fatigue. Therefore, the bathtub is designed as a container for storing hot water, and is generally made of reinforced plastic.

On the other hand, there has been proposed a tendency to reconsider bathing as a place of mental comfort, and in response to such a tendency, indirect lighting or BGM device is introduced in the bathroom, or a new function other than the water storage function is added to the bathtub. It has been attempted to obtain various functions, for example, a lighting device is installed on the back surface of the peripheral wall of the bathtub body so that the interior of the bathtub can be illuminated and comfort is achieved by combining water and light (see Japanese Utility Model Publication No. 62-136892). .

[0004]

However, in such an illumination method, only a part of the bathtub is illuminated, and variations in brightness occur, and if the bathtub is damaged,
There was a problem that water was splashed on the lighting equipment, which was dangerous, and it was difficult to carry out waterproofing and maintenance.

The present invention has been made in view of the above problems, and provides a bathtub capable of safely producing comfort in which water and light are combined.

[0006]

According to the present invention, a bathtub-shaped photoconductive plate as a bathtub body, and both ends of the photoconductive plate as the bathtub body facing each other are sandwiched between the photoconductive plate and a light source. It is characterized in that it comprises an illumination box having a built-in lamp, and guides the light from the light source of the illumination box to a photoconductive plate as a bathtub body for surface emission.

[0007]

[Operation] When the light source of the lighting box is turned on, the light enters the inside of the photoconductive plate formed in the bathtub body, and is reflected by the reflective layer to emit light from the bathtub, so that the comfort of light and water is produced. To do.

At this time, since the lighting box is arranged at the edge of the bath body, maintenance and inspection are easy, and waterproofness and safety are surely secured.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a bathtub 1 of the present invention. The bathtub 1 includes a photoconductive plate 2 shaped like a bathtub as a bathtub body, and a photoconductive plate 2 as the bathtub body.
Of the illumination box 3 sandwiched between the two opposing edge portions. The photoconductive plate 2 as the bath body and the illumination box 3 constitute an illumination device.

The photoconductive plate 2 formed in the bath body is
It is formed of an acrylic resin transparent plate 21 having a reflective layer 22 dot-printed on its back surface and a backup sheet 23 attached to the back surface of this acrylic resin transparent plate 21. On the other hand, the lighting box 3 is composed of a light source 31 such as a fluorescent lamp and a cover 32 surrounding and fixing the light source 31, and holds two opposing edge portions of the photoconductive plate 2 formed in the bath body described above. Are arranged. That is, one illumination box 3 is continuously provided on one wall panel 4, and the other illumination box 3 is continuously provided on a waterproof pan 5 that forms a washing area.

As a result, when the light source 31 is energized, the light enters the photoconductive plate 2 as the bath body from both end surfaces thereof, is reflected by the reflective layer 22 and goes out to the surface side. At this time, the backup sheet 24 prevents light from leaking to the back side from other than the reflection layer 22 by dot printing, and makes the entire photoconductive plate 2 emit light.

Therefore, in the bathtub 1, when the light source 31 of the illumination box 3 is turned on, the photoconductive plate 2, that is, the bathtub body emits light to illuminate the bathroom. As a result, it is possible to produce comfort that combines light and water. Further, since the lighting box 3 is also provided at a position away from the inner peripheral surface that serves as a water storage portion of the bathtub body, it is possible to ensure waterproofness and safety, and also to facilitate maintenance and inspection of the light source.

The photoconductive plate 2 emits light in a large range in the lengthwise direction in proportion to the amount of light entering from the end face of the acrylic resin transparent plate 21, but at least up to a position just below the water surface stored in the bath body. Such an amount of light is desirable. When such a light emission is selected, the depth of the acrylic resin transparent plate 21 can be produced.

When the surface side of the acrylic resin transparent plate 21 is treated with a solvent to form a ground glass,
The light entering from the end surface of the acrylic resin transparent plate 21 is diffused,
The entire surface of the photoconductive plate 2 can be made to emit light uniformly.

[0016]

As described above, according to the present invention, the bathtub-shaped photoconductive plate as the bathtub body and the opposite end edges of the photoconductive plate as the bathtub body are sandwiched and arranged. , A light box with a built-in light source. By guiding the light from the light source of the light box to the photoconductive plate as the bathtub body for surface emission, it becomes possible to illuminate using the bathtub body, lighting and water. In addition to expressing comfort by combining, it is possible to ensure safety and waterproofness, and to easily perform maintenance and inspection.
