Abstract

An illumination device is provided on the back surface side of the bath tab vessel for receiving water formed of a transparent material or a translucent material. Furthermore, in a bath tab unit having a double-hulled structure consisting of an inner vessel and an outer vessel, the inner vessel is formed of a transparent material or a translucent material, and an illumination device is provided in a space between the inner vessel and the outer vessel.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A bath tab with a built-in illumination device, wherein an illumination device is provided on the back surface side of a bath tab vessel for receiving water formed of a transparent material or a translucent material.  
     
     
         2 . A bath tab with a built-in illumination device according to  claim 1 , wherein the bath tab vessel is formed of a plastic material.  
     
     
         3 . A bath tab with a built-in illumination device according to  claim 1 , wherein the bath tab vessel is formed of a thermosetting material.  
     
     
         4 . A bath tab with a built-in illumination device according to  claim 1 , wherein the illumination device illuminates the whole surface of the inner vessel.  
     
     
         5 . A bath tab with a built-in illumination device according to  claim 1 , wherein the illumination device illuminates a part of the inner vessel.  
     
     
         6 . A bath tab with a built-in illumination device according to  claim 4  or  5 , wherein the illumination device is a liquid crystal display for displaying color images.  
     
     
         7 . A bath tab with a built-in illumination device according to  claim 4  or  5 , wherein the illumination device is a lamp.  
     
     
         8 . A bath tab with a built-in illumination device according to  claim 4  or  5 , wherein the illumination device is a light emitting diode.  
     
     
         9 . A bath tab with a built-in illumination device according to  claim 4  or  5 , wherein the illumination device is a combination of a light emitting diode and an optical fiber.  
     
     
         10 . A bath tab with a built-in illumination device according to  claim 9 , wherein illumination is achieved by the tip end portion of the optical fiber.  
     
     
         11 . A bath tab with a built-in illumination device according to  claim 10 , wherein illumination is achieved by the side surface of the optical fiber.  
     
     
         12 . A bath tab with a built-in illumination device according to  claim 4  or  5 , wherein the illumination device is a combination of a light source and a fluorescent member.  
     
     
         13 . A bath tab with a built-in illumination device according to  claim 12  further comprising an optical fiber.  
     
     
         14 . A bath tab with a built-in illumination device according to  claim 4  or  5 , wherein the illumination device is an EL.  
     
     
         15 . A bath tab with a built-in illumination device having a double-hulled structure consisting of an inner vessel which forms a bath tab and receives water and an outer vessel, wherein the inner vessel is formed of a transparent material or a translucent material, and an illumination device is provided in a space between the inner vessel and the outer vessel.  
     
     
         16 . A bath tab with a built-in illumination device according to  claim 15 , wherein the illumination device is attached to the outer vessel so as to illuminate the whole surface of the inner vessel.  
     
     
         17 . A bath tub with a built-in illumination device according to  claim 15 , wherein the illumination device is attached to the outer vessel so as to illuminate a part of the inner vessel.  
     
     
         18 . A bath tab with a built-in illumination device according to  claim 16  or  17 , wherein the illumination device is a liquid crystal display for displaying color images.  
     
     
         19 . A bath tab with a built-in illumination device according to  claim 16  or  17 , wherein the illumination device is a lamp.  
     
     
         20 . A bath tab with a built-in illumination device according to  claim 16  or  17 , wherein the illumination device is a light emitting diode.  
     
     
         21 . A bath tab with a built-in illumination device according to  claim 16  or  17 , wherein the illumination device is a combination of a light emitting diode and an optical fiber.  
     
     
         22 . A bath tab with a built-in illumination device according to  claim 16  or  17 , wherein the illumination device is a combination of a light source and a fluorescent member.  
     
     
         23 . A bath tab with a built-in illumination device according to  claim 22  further comprising an optical fiber.
