2. Description of the Related Art Toilet drain pipes, particularly drain pipes for men's toilets, form scales called urinary stones to which a mixture of calcium compounds and organic substances formed by the decomposition of urine is fixed, and urine and urine are discharged. The flow of washing water is deteriorated, and in extreme cases, the drain pipe is closed, and the toilet becomes unusable. In addition, the organic matter in urine stones is spoiled by bacteria and generates a bad smell. The odor of men's toilets is a mixed odor of ammonia generated by decomposition of urine and odor caused by decomposition of organic matter.

[0003] Conventionally, as a method for preventing the scale of a toilet drain pipe, a method of injecting a drug into the middle of a washing water pipe and a method of putting a spherically shaped drug into a toilet of a men's toilet have been put to practical use. Various agents containing a surfactant, a bactericide and a fragrance have been proposed as agents used in these methods. For example, Japanese Patent Publication No. 45-30
No. 706 describes a deodorant detergent for flush toilets obtained by melt-mixing a surfactant, an ion-sequestering agent, a fragrance and the like with polyethylene glycol or polypropylene glycol and an aromatic substance, and casting the mixture. 57-1

It prevents scale from sticking to the pipe, but also removes scale from the toilet drain pipe, and is a scale control agent. Further, as a method for controlling the scale once stuck to the toilet drain pipe, a method of dissolving the scale using an inorganic strong acid such as hydrochloric acid, and a method of removing the toilet and mechanically removing the scale are adopted.

There is no corrosion of the toilet drain pipe or a decrease in the purification capacity of the septic tank, and the scale of the toilet drain pipe is prevented from sticking only to the toilet drain pipe without removing the scale fixed to the toilet drain pipe. Many methods and scale inhibitors have been proposed. For example, an aqueous solution containing one or more acidic substances selected from mineral acids, organic acids, water-soluble acidic salts, water-soluble salts of a strong acid and a weak base, and sulfamic acid in urine and / or washing water is used.

An uric acid inhibitor obtained by heating and mixing an organic acid thus formed, mixing a solid acid with a mixture in a molten state, and then molding is described.

[0007]

The above-mentioned Japanese Patent No. 29287 is disclosed.
No. 72 and the like disclose the formation of urinary calculus and prevention of urinary stone sticking as follows. Urine usually contains 200 to 300 ppm of water-soluble calcium ions and 2000 to 2500 ppm of phosphate ions. Further, carbonate ions are contained in the wash water, and carbon dioxide gas in the atmosphere is dissolved and supplied. The pH of urine excreted from the body is 5.
Although it is about 5 to 6.5, the pH gradually rises when left in the air, and eventually reaches 9 to 9.5. When the pH becomes 7.5 or more, turbidity occurs, and the turbidity rises with the increase in pH. When the pH becomes 8.5 or more, a white precipitate of calcium apatite precipitates, and calcium carbonate is formed on the contact surface with the atmosphere. Crystals form in the form of a film. The crystals of calcium apatite and calcium carbonate adhere to the drain pipe of the toilet together with effective substances such as water-insoluble proteins generated by the action of bacteria and enzymes, and grow to a scale generally called urolith. The scale is a mixture of 40 to 60 wt% of calcium apatite [Ca ₅ (PO ₄ ) ₃ OH], 20 to 40 wt% of calcium carbonate [CaCO ₃ ], and 10 to ₃₀ wt% of an organic substance insoluble in water. Does not precipitate in water having a pH of 7.5 or less,
H is in the range of 7.5 to 8.5 even if it is precipitated, the amount is extremely small, and it takes a long time for the precipitation, and urine or mixed waste water of urine and washing water contains urinary degrading enzymes and bacteria. By generating ammonia and raising the pH in a short time by the action of the above, or by maintaining the pH of urine or a mixed waste water of urine and washing water at 8.5 or less, preferably 7.5 or less, the toilet If the scale can be prevented from sticking to the drain pipe, or if the pH of urine or mixed waste water of urine and washing water is too low to remove the scale fixed to the toilet drain pipe, corrosion of the drain pipe becomes a problem. The preferred lower limit of the pH of urine or mixed waste water of urine and washing water is 5, and preferably 5.5.

[0008] The pH of urine or mixed waste water of urine and washing water is adjusted to 5
To 8.5, no erosion of the toilet drain pipe and no decrease in the purification capacity of the septic tank. Toilet drainage that only prevents the scale from sticking to the toilet drain pipe without removing the scale that has adhered to the toilet drain pipe. The method for preventing scale adhesion and the agent for preventing scale adhesion of pipes have already been put to practical use and can be said to be extremely high in perfection. However, in a trap-removable toilet, the pH of trapped water is set to 5 to 8.5. When the water is retained, the trapped water is diluted by the inflow of urine and washing water, and the prevention of the scale from sticking to the toilet drainpipe is actually insufficient. I found something. An object of the present invention is to provide a detachable trap that can be advantageously used to easily and efficiently prevent sticking of a scale in a trap detachable toilet and for a long period of time.

[0009]

Means for Solving the Problems The present inventor has made intensive studies to solve the above-mentioned problems, and the trap reservoir in most of the trap-removable toilets is made of pottery or plastic, so that there is no fear of corrosion. Inspired by that,
When the pH of the trapped water was maintained at 3.5 to 4.5, the trapped water was diluted by the inflow of urine and washing water, and the toilet drain pipe was contacted with a mixed water of pH 5.0 to 6.0. However, it has been found that the scale can be prevented from sticking to the trap pool and the toilet drain pipe. Based on this knowledge, a method for easily maintaining the pH of the trapped water at 3.5 to 4.5 over a long period of time was studied, and a solid-type scale inhibitor containing a solid acid as an active ingredient was applied to a bag made of nonwoven fabric. When the bag is stored and latched and held in a state in which a predetermined portion of the bag is immersed in the trapping water, a predetermined volume of the solid type scale inhibitor in the bag is immersed in the trapping water and the immersed portion is dissolved. However, the non-immersed part moves downward and is newly immersed in the trapping water, and the volume part constantly immersed in the trapping water is kept almost constant. It was found that it became easier, and then a hooking means was provided on the detachable trap of the trap detachable toilet, and the bag containing the solid type scale preventive agent was held at a predetermined constant height. The pH of sure that can be maintained in 3.5-4.5, and have completed the present invention.

"ELEVES S0403WDO", a basis weight; 40g / m ^3, a thickness of 0.25 mm) was used. This non-woven fabric has a predetermined size (80 mm long, 60 mm wide, 8 mm back seal part)
, Heat-sealed on three sides, packaged the formed body described above, heat-sealed the remaining one side, and stored the formed body S as shown in FIG. Was manufactured. Next, as shown in FIG. 4, after inserting a flexible cord into a hook portion of the toilet scale preventer, that is, a hole provided in a peripheral heat seal portion of the bag body, A ring R to which the parts were connected was provided, and a toilet scale preventive device having a hanging portion was manufactured.

(Use of Toilet Scale Prevention Tool in Removable Trap) FIG. 3 shows the toilet scale prevention tool held by the detachable trap 1 of the present invention used in a trap portion of the trap detachable toilet. The state is shown. The men's toilet shown in FIG. 3 is a so-called trap detachable toilet in which no trap is provided in the drain pipe 9, and the detachable trap 1 is removably incorporated in the bottom of the toilet 8. As described above, the detachable trap 1 has the holding lid 4 to which the hook 6 is fixed on the lower surface, and the ring R of the toilet scale preventive device is hooked on the hook 6 to store the molded body S. A part of the bag body is immersed in the pool water.

When urine and / or washing water flows into the trap water storage section from the gap between the detachable trap 1 and the toilet bowl 8, the molded body S stored in the bag is mixed with the immersed water. At this time, the pH of the trap pool water is 3.5 to 4.5,
Since the position of the molded body S, the dissolution rate of the molded body, the type of the water-permeable material, the thickness and the density, and the like are adjusted so that the pH is preferably about 4.0, the elution of the solid organic acid through the nonwoven fabric is performed. As a result, the pH of the trapped water was maintained at 3.5 to 4.5. As a result, it was found that no adhesion of urine stone was observed, and that the life of the drug almost coincided with the rental period (about one month). When the pH of the trapped water is maintained at 3.5 to 4.5, the trapped water is diluted by the urine and the washing water that have flowed in, and the pH of the toilet drain pipe is adjusted to pH 5.0 to 6.0.
Mixed water flows in and scale can be prevented from sticking to the toilet drain pipe.
