Abstract

(57) [Summary] [Purpose] To further improve the texture and add a texture not found in natural stone. An optical fiber 4 is embedded in a bath body 3 having an opaque layer 1 on the outer surface side and a transparent or semitransparent layer 2 on the inner surface side. One end of the fiber 4 is positioned inside the bath body 3 and the other end of the optical fiber 4 is connected to the light source 5.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a bathtub that can improve the atmosphere when taking a bath.

[0002]

[Prior Art]

 In recent years, various bathtubs have been provided to improve the atmosphere during bathing. For example, as shown in FIG. 8, a bath body 3 is formed by an opaque resin layer 1 and a transparent or translucent resin layer 2, and flakes such as aluminum are mixed in the transparent or translucent resin layer 2. By doing so, a bathtub that can give the texture of natural marble is provided.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, there is a problem that the appearance can only give a natural marble-like atmosphere, and there is still little change when taking a bath. The present invention is intended to solve the above problems, and an object of the present invention is to provide a bathtub capable of further improving the texture and adding a texture not found in natural stone.

[0004]

[Means for Solving the Problems]

 In the present invention, in order to achieve the above object, an optical fiber 4 is embedded in a bathtub body 3 having an opaque layer 1 on the outer surface side and a transparent or semi-transparent layer 2 on the inner surface side. One end is located inside the bath body 3 and the other end of the optical fiber 4 is connected to the light source 5.

[0005]

[Action]

 Then, the light from the light source 5 emits light at the end of the optical fiber 4 arranged inside the bathtub body 3, and the inner surface side of the bathtub body 3 emits light. The atmosphere can be improved by lighting.

[0006]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. The bath body is made by a casting method, and as shown in FIG. 1, an FRP backup layer as an opaque layer 1, a casting resin layer as a transparent or translucent layer 2, and a transparent layer. 6 as a gel coat layer. As the casting method, there are a casting method and a hand layup method. Fig. 6 shows the structure of the electroforming mold in the casting method. The molding flow is as shown in FIG. 7, but after mounting the FRP backup layer, which was formed in advance to about 1 mm 2 according to the shape of the back surface of the bath body 3, on the upper mold 7, and after tightening the upper and lower molds 7, 8. The casting resin is injected and the upper and lower molds 7 and 8 are heated to cure the resin. Reference numeral 18 is a hot water copper pipe for heating the upper and lower molds 7 and 8, and 19 is a resin injection port. Then, a plurality of optical fibers 4 are fixed to the inner surface of the FRP backup layer before the injection of the casting resin, and by injecting the casting resin in this state, the optical fibers 4 are inserted into the bath body 3 as shown in FIG. It is buried. One end of the optical fiber 4 is arranged inside the bath body 3, and the other end of the optical fiber 4 is connected to the light source 5 in a state in which a plurality of optical fibers 4 are collected as shown in FIG.

As shown in FIG. 4, the light source 5 is configured such that a down transformer 9, a lamp 10, a fan 11, a motor 12, a filter 13, and a heat ray absorbing glass 14 are housed and arranged in a storage box 5 a, respectively. The other end of the optical fiber 4 is connected to a connector 15 arranged in front of the filter 13. As shown in FIG. 5, the filter 13 is provided with colored portions 13a and transparent portions 13b alternately, and by rotating the filter 13 by the motor 12, the color of the light emitted from the end portion of the optical fiber 4 is changed. It can be arbitrary.

The light from the light source 5 is supplied to the inside of the bath body 3 from the end portion of the optical fiber 4 embedded in the bath body 3, whereby the interior of the bath body 3 emits light. As the bathtub body 3 itself emits light, it is possible to realize a texture that has never been seen before. Here, by mixing flakes of aluminum or the like in the casting resin layer as the transparent or semi-transparent layer 2, the light emission state can be changed by projecting the flakes, and the texture is further improved. Is something that can be done.

FIG. 3 shows another embodiment, in which a small hole 16 is formed in the FRP backup layer as the opaque layer 1, and the optical fiber 4 is inserted into this small hole 16. And is fixed with an adhesive 17. With this configuration, the end surface of the optical fiber 4 can be arranged toward the inner surface of the bath body 3, and the light from the optical fiber 4 can be efficiently supplied into the bath body 3. It has become like this. Here, the light emitting state can be set to an arbitrary state by adjusting the height dimension H of the optical fiber 4 to be inserted into the small hole 16.

[0010]

[Effect of the device]

 As described above, the present invention embeds an optical fiber in a bath body having an opaque layer on the outer surface side and a transparent or semi-transparent layer on the inner surface side, and positions one end of the optical fiber in the bath body. Also, since the other end of the optical fiber is connected to the light source, the light from the light source emits light at the end of the optical fiber arranged inside the bathtub body, which causes the inner surface of the bathtub body to emit light and It is supplied with light and can create an unprecedented atmosphere, and lighting can improve the atmosphere during bathing.
