[Detailed description of the invention] This invention is a water storage tank for a flush toilet equipped with a lighting equipment, which prevents condensation on the inner surface of the glove that surrounds the lighting equipment to separate it from the water storage. It concerns water tanks.

Conventional water storage tanks with lighting equipment have patent no.
As seen in the water storage tank that also serves as a lighting fixture for a flush toilet in No. 1121890, various inventions have been made by the applicant, and these water tanks have lighting fixtures with various aesthetic designs placed inside the water tank body. In addition, a window is formed on the peripheral wall of the water tank body by fitting a transparent plate for the purpose of transmitting the light emitted from the lighting equipment. It is designed to create a fantastical beauty inside the dry toilet.

However, when cold water is supplied into the water tank body under conditions where the temperature inside the toilet is relatively high, moisture in the air may condense on the surface of the water tank body, and the transparent plate in the window part If dew condensation occurs on the surface, it will significantly impede the lighting effect, so the applicant of the present application filed the application No. 59-159076 (U.S. Pat. A sealed space is formed between the two transparent plates, and an appropriate gas that does not contain moisture or oxygen is filled in the space to prevent dew condensation on the surface of the window. He came up with a water tank with a lighting fixture for a flush toilet that completely prevents the occurrence of this problem.

However, although the above configuration alone can prevent dew condensation on the window, the globe that covers the lighting body inside the water storage tank for the purpose of shielding it from water storage cannot be completely sealed because it requires an opening for replacing the light bulb. As a result, dew condensation occurs on the inner surface of the globe, which interferes with the lighting effect, which has the disadvantage of reducing the aesthetic value of a water tank with a lighting fixture, which is intended to create a luxurious atmosphere. Ta.

In view of these drawbacks, the present invention provides a water storage tank with a lighting device in which a lighting device is disposed inside the water storage tank body, in which a globe that hangs down from the lid body into the water storage tank body is inserted into the lighting body.

A liquid level control device 4 such as a ball tap valve or the like is provided so that a predetermined water level is maintained in the water storage tank body 1 by the action of the liquid level control device 4.

Reference numeral 5 denotes a lighting fixture that is installed inside the water tank body 1, and a lid 6 has a globe 7 molded from a transparent material such as glass or synthetic resin, which is attached to the support part 8 and placed in the water stored in the water tank body 1. The globe 7 is screwed and supported in a hanging position so as to be submerged in water. The upper end of the cylindrical body 10 is integrally joined to provide a sealed space 11 between the inner cylindrical body 9 and the outer cylindrical body 10, and when the space 11 is sealed, moisture and oxygen are removed. An appropriate gas consisting of an inert gas such as helium, neon, argon, etc., which does not contain carbon dioxide, has low thermal conductivity, and is safe in terms of nonflammability, etc., is sealed, while the upper end of the inner cylindrical body 9 is left open. The opening of the lever serves as the insertion port 12.

The purpose of filling the space 11 with gas is to completely prevent the propagation of bacteria, bacteria, etc. in the space 11, and to maintain the outer surface of the inner cylindrical body 9 and the inner surface of the outer cylindrical body 10 in a clean state. be.

Further, hot wire heaters 13 are attached to the circumferential surface of the inner cylindrical body 9 in an appropriate arrangement such as a folded shape or a coil shape in the vertical direction so that they are evenly distributed over the entire surface, and the hot wire heaters 13 are attached to the power supply section. The connection (wiring omitted) is made to heat the circumferential surface of the inner cylindrical body 9.

Reference numeral 14 denotes a rod-shaped illumination body, which is made up of an elongated cylindrical receptacle tube 15 whose outer diameter is slightly smaller than the inner diameter of the insertion opening 12, and a light bulb 16 of an appropriate type that is replaceably attached to the lower end of the receptacle tube 15. Cylinder 15
A holder 19 that fits into a jetty 17 projecting from the upper surface of the support part 8 and has a handle 18 formed on the outer periphery is mounted on the upper end of the holder 19.
The illumination body 14 is tightly inserted into the inner cylindrical body 9 by the fitting action of
A cover body 20 covering the upper part of the body 4 is detachably screwed on.

Further, an opening is formed through the front surface of the peripheral wall 2 of the water tank body 1 facing the lighting fixture 5 to form a window 21.
The window portion 21 is composed of two transparent plates 23, 23a made of a transparent or semi-transparent material such as glass or synthetic resin, which are arranged opposite to each other at a predetermined interval with a frame 22 in between. And the transparent plates 23, 23
A sealed space 24 is formed between a.

In addition, a transparent plate 2 is placed in the space 24 via the frame 22.
3 and 23a, an appropriate gas consisting of an inert gas such as helium, neon, or argon, which does not contain moisture or oxygen, has low thermal conductivity, and is safe in terms of nonflammability, is filled. There is.
