Description

[Detailed Description of the Invention] The present invention relates to an improvement of a water storage tank for toilet flush water that has excellent dew condensation prevention and noise reduction effects.

Conventional toilet flush water tanks are simply tanks made of ceramic or synthetic resin, so if the indoor temperature and the temperature of the stored water are high, water droplets will condense on the outside of the tank and drip. , there are defects that stain the floor etc.

Therefore, an idea has been proposed in which the water tank is made up of an inner tank and an outer tank and is filled with heat insulating material for calibration. There are various disadvantages such as the possibility that the insulating material may leak out during use.

The present invention was completed with the aim of creating a water storage tank for flushing water for toilet bowls that eliminates the above-mentioned drawbacks. A thin synthetic resin tank 3 is provided with a short cylindrical part 2 for drainage, and an inner tank 5 is formed by integrally laminating a porous synthetic resin layer 4 having independent pores on the outer surface of the tank 3. A drain fitting 8 is fitted into an outer tank 7 having an opening 6 at the bottom, and a drain fitting 8 is fitted to the drain opening 6.
It is made by attaching.

In addition, in the first embodiment shown in FIG. 1, 9 in the figure is provided between the peripheral surface of the inner tank 5 and the outer tank 7 as necessary when the outer tank 7 is made of ceramic. A gap 10 is used to further enhance the effect between the inner tank 5 fitted in the outer tank 7 and the outer tank 7.
In the second embodiment using the synthetic resin outer tank 7 shown in FIG. A projecting plate portion 14 is bent at a substantially right angle and arranged in a row to enable the inner tank 5 to be adhered to the outer tank 7 with an adhesive 10 and tightened with screws 13 accurately and easily. A frame plate 15 made of a rust-free steel plate is interposed as necessary between the projecting plate part 12 and the bottom of the outer tank 7, and 15 is a drainage device such as a ball tap.

The device constructed in this way is installed and used in the toilet by connecting the drain fitting 8 to the drain pipe and connecting the water supply pipe to the water supply port, similar to a conventional toilet flush water tank. However, since the drain port 6 provided at the bottom of the outer tank 7 has a smaller diameter than the short cylindrical portion 2 provided at the bottom of the inner tank 5, when attaching the drain fitting 8 to the drain port 6, There is no risk that the porous synthetic resin layer 4 having independent pores, such as porous styrene resin, on the outer surface of the inner tank 5 will buckle and collapse.
Accurate piping without water leakage is possible, and the outer tank 7 is made of a synthetic resin material such as A-B-3 resin, hard vinyl chloride resin, polyester resin, or ceramics, and the A - A thin synthetic resin tank 3 obtained by forming a thermoplastic synthetic resin sheet such as a B-5 resin sheet into a tower shape using a vacuum forming method is a thin synthetic resin tank 3 that is layered and integrated on the outer surface of the synthetic resin tank 3. The porous synthetic resin layer 4 with independent pores provides thermal insulation, and even if there is a significant temperature difference between the stored water and the room temperature, there is no risk of water droplets condensing on the outer surface of the outer tank 7, and there is no risk of condensation inside the inner tank 5. The sound of running water being supplied from the water supply pipe is blocked, resulting in a product with excellent noise reduction effects.

In addition, the thin synthetic resin tank 3 on the inner surface of the inner tank 5 is strong enough not to be damaged by running water, and the top opening edge and the bottom drainage opening face outward with the short flange 1 and the short flange 3. Since the inner tank 5 is reinforced by the cylindrical part 2, it has sufficient strength, and the cushioning properties of the porous synthetic resin layer 4 on the outer surface of the inner tank 5 protect not only the inner tank 5 itself but also the outer tank 7. It also has the advantage of being able to last for a long time in addition to being protected.

However, in order to manufacture such a water storage tank for toilet flush water, for example, the short flange portion 1 is formed by vacuum forming a synthetic resin sheet.
The inner tank 5 is mass-produced by forming a thin synthetic resin tank 3 having a short cylindrical part 2 and a porous synthetic resin layer 4 having independent pores on its outer surface. The drain fitting 8 can be attached to the drain port 6 provided at the bottom of the outer tank 7 by fitting it into the outer tank 7 which has been mass-produced using ceramics or synthetic resin material by a conventional method and fixing it with adhesive or the like. Therefore, there are advantages such as no need for manufacturing manpower, mass production is possible at low cost, and there is no risk of the porous synthetic resin layer 4 peeling off and flowing out.

Therefore, the present invention has great practical value as it eliminates the drawbacks of the conventional toilet flush water storage tank.

Claims (1)

[Scope of utility model registration request] A porous synthetic resin layer 4 having independent pores is integrally layered on the outer surface of a thin synthetic resin tank 3, which has a short outward facing flange 1 at the upper opening edge and a short cylindrical part 2 for drainage at the bottom. This water storage tank for toilet flush water is constructed by fitting an inner tank 5 made of a small tube into an outer tank 7 having a drain port 6 at the bottom with a diameter smaller than that of the short cylindrical portion 2, and attaching a discharge fitting 8 to the drain port 6.
