Description

  The present invention relates to an illuminated bathtub apparatus that can illuminate a bathtub using illumination.

  Patent Document 1 discloses an illuminated bathtub apparatus that can be provided with a light source in which a plurality of optical fibers are knitted in a net-like shape on the back side of a light-transmitting bathtub so that the bathtub can be illuminated circumferentially. ing.

  However, in the apparatus described in Patent Document 1, since the optical fiber is arranged in a region without the coating film on the back surface of the bathtub, the light transmitted through the inner surface of the bathtub is not coated with the coating film on the back surface of the bathtub. Since light and dark are clearly divided into parts, there is a problem that a high-class feeling cannot be produced and the design is applied.

  In addition, since the striped optical fiber is directly arranged on the back surface of the bathtub, it is difficult to give gradation to the light emission part light amount.

  Furthermore, although patent document 1 has description about the color of the light which permeate | transmits the bathtub inner surface, description of gradation is not made | formed and the device point for that cannot be found.

FIG. 1 is an exploded perspective view of an illuminated bathtub apparatus according to an embodiment of the present invention.
Moreover, FIG. 2 is a top view of the bathtub apparatus with illumination concerning embodiment of this invention.
FIG. 3 and FIG. 4 are enlarged cross-sectional views showing the illuminating bathtub device features according to the embodiment of the present invention.

  As shown in FIGS. 1 to 3, the illuminated bathtub device according to the present invention includes a bathtub 10, a light source 40, a reflector 30, a dimmer 20, and a light shield 50.

  The bathtub 10 is formed from a transparent material having translucency, and can store bathtub water therein. Moreover, the colored layer (for example, milky white) which has translucency is formed in the back surface side of the bathtub 10. As shown in FIG. Since the bathtub 10 becomes translucent by providing the colored layer, members such as a light source disposed on the back side of the bathtub 10 cannot be visually recognized from the inside of the bathtub 10. In addition, since it is a colored layer which has translucency, it is possible to make the inner surface of the bathtub 10 shine by irradiating light from the bathtub 10 back side.

  The light source 40 is a plurality of LEDs connected in a band shape by a flexible connecting body, and is arranged in a circumferential shape so as to surround the outside of the bathtub 10. As shown in FIG. 3, a more specific installation position of the light source 40 is near the back side of the boundary portion between the bottom surface portion 11 and the side surface portion 12 of the bathtub 10, and is spaced from the back surface of the bathtub 10. It is arranged substantially horizontally.

  The reflector 30 is a container whose upper surface is opened, and the lower side of the bathtub 10 can be accommodated therein. A space is formed between the reflector 30 and the bathtub 10, and a light source 40 is disposed in the space. Since the light emitted from the light source 40 can be reflected toward the bathtub 10 by the reflector 30, the bathtub can be brightened as compared with the case where there is no reflector.

  The dimming body 20 is made of a translucent material and has semi-translucency. The dimming body 20 is fixed to the reflector 30 so as to partition the space between the reflector 30 and the back surface of the bathtub 10 and to surround the outside of the bathtub 10. For this reason, when the light emitted from the light source 40 passes through the dimming body 20, the amount of light is attenuated, and it is possible to add gradation to the light emitting region on the inner surface of the bathtub 10. The dimming body 20 has a cushioning property that can be elastically deformed, and is always designed to come into contact with the outer surface of the bathtub 10 when the bathtub 10 is accommodated in the reflector 30. By doing in this way, it becomes possible to partition the space between the bathtub 10 and the reflector 30 without a gap. FIG. 3 is a view showing the relationship between the bathtub 10 and the reflector 20 in a state where the dimming body 20 is not deformed, and FIG. 4 is a view showing a state where the dimming body is actually deformed. Moreover, even if it is a case where the clearance gap between the bathtub 10 and the reflector 30 has shifted | deviated somewhat because the light attenuation body 20 has cushioning properties, a shift | offset | difference can be absorbed.

  The light shielding body 50 is colored in color (for example, black) in order to have light shielding properties. Further, the light shielding body 50 is fixed to the reflector 30 in a circumferential shape so as to partition the space between the reflector 30 and the back surface of the bathtub 10 and to surround the outside of the bathtub 10. Further, the light blocking body 50 is disposed at a position farther from the light source 40 than the light reducing body 20 (periphery side of the reflector 30), and plays a role of completely blocking light that has passed through the light reducing body 20. By providing the light-shielding body 50, the area that emits light and the area that does not emit light can be completely separated on the inner surface of the bathtub 10. Moreover, the light shielding body 50 has a cushioning property that can be elastically deformed, and is always designed to come into contact with the outer surface of the bathtub 10 when the bathtub 10 is accommodated in the reflector 30. By doing in this way, it becomes possible to partition the space between the bathtub 10 and the reflector 30 without a gap. FIG. 3 is a diagram showing the connection between the bathtub 10 and the reflector 20 in a state where the light shield 50 is not deformed, and FIG. 4 is a diagram showing a state where the light shield 50 is actually deformed. Moreover, even if it is a case where the clearance gap between the bathtub 10 and the reflector 30 has shifted | deviated somewhat because the light-shielding body 50 has cushioning properties, a shift | offset | difference can be absorbed.

  With the above configuration, the region 100 in which the inner surface of the bathtub 10 shines deeply (the portion that emits light by light not passing through the dimming body 20) and the region 110 in which the inner surface of the bathtub 10 does not shine (the light shielding member 50 blocks light). The gradation region 120 (the portion that emits light by the light that has passed through the dimming body) in which the inner surface of the bathtub 10 shines lightly is formed.

  Further, according to the present embodiment, the gradation is further gradually increased in the gradation area 120. Specifically, by making the dimming body 20 as shown in FIG. 4, three spaces (first space 200, first space 200) formed by the outer surface of the bathtub 10, the reflector 30, and the light blocking body are formed. Divided into two spaces 210 and a third space 220).

The first space 200 is a bathtub-side space that forms the above-described darkly shining region 100 (a portion that emits light by light that has not passed through the dimming body 20), and is a space in which the light source 40 is accommodated. The second space 210 is a space surrounded by the reflector 30 and the dimming body 20, and is a part of the bathtub back side space forming the gradation region 120 described above. The second space 210 can make the inner surface of the bathtub 10 shine by the light attenuated by passing through the dimming body 20. In addition, since the reflector 30 is in the second space 210, the light in the second space 210 is reflected toward the bathtub 10 by the reflector 30. The third space 220 is a space surrounded by the light reducing body 20, the outer surface of the bathtub 10, and the light blocking body 50, and is a part of the bathtub back side space forming the gradation region 120 described above. In this third space 220, only the light that has further passed through the dimming body 20 from the second space 210 enters, so that the amount of incident light is absolutely smaller than that of the second space 210. In the third space 220, the reflector 30 is covered with a part of the dimming body 20. Further, the portion of the light reducing body 20 that covers the reflector 30 is colored in a light-shielding color (for example, black). In other words, since the reflector 30 does not exist in the third space 220, the light shines more lightly than the second space 210.

  In this way, by reducing the amount of reflection by the reflector 30 toward the region where the bathtub does not shine, it becomes possible to create gradation in steps in the gradation region.
