[0003] In the above-mentioned conventional cleaning method, only the toilet is to be cleaned, but dirt due to organic matter such as black mold adheres to the inside of the water supply tank and the water supply pipe from the tank to the toilet. It emits a bad smell, and this dirt flows out of the water supply pipe into the toilet and soils the toilet.

In a conventional cleaning method using a chemical cleaning agent, a rubber sealing material or a synthetic resin material used for a pipe of a flush toilet or a valve in a water supply tank is damaged by acid or alkali of the chemical cleaning agent. Cleaning other than the toilet bowl could not be performed.

[0005] Further, in the conventional method using a chemical cleaning agent, there is a danger that a toxic gas may be generated in the human body when different types of chemical cleaning agents are mixed.

Further, when the sewage tank of the flush toilet is, for example, an aeration-type septic tank, microorganisms living in the septic tank and decomposing organic substances are killed by the acid or alkali of the chemical cleaning agent, and the function of the septic tank is reduced. There is also a problem of impairing.

In addition to the cleaning method described above, a cleaning agent containing a surfactant or a fragrance as a main component is added to a water supply tank to perform cleaning without damaging a water supply pipe or the like, or to decompose organic matter from cultured microorganisms. There are various methods such as extracting the enzyme and washing the toilet with a detergent containing this enzyme.Each method has a low cleaning effect, and in the past, it was sufficient and reliable to flush the toilet without damaging the water supply tank and piping. There was no cleaning method or cleaning agent capable of removing dirt.

Further, the microorganism in the detergent is any one of a microorganism capable of producing an amylolytic enzyme, a microorganism capable of producing a proteolytic enzyme, a microorganism capable of producing an animal and vegetable oil and fat degrading enzyme, and a microorganism capable of producing a cellulolytic enzyme. Alternatively, these microorganisms are present at an appropriate ratio.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a flush toilet cleaning method and a cleaning agent according to the present invention will be described below with reference to the accompanying drawings. The microorganism used in the present invention is, for example, Bacillus subtilis (Bacillus subtilis) having an ability to produce amylase as a starch-degrading enzyme and protease as a proteolytic enzyme.
And Bacillus licheniformis (Bacillus licheniformi) capable of producing lipase,
s) and Bacillus polymia (Bacillus) having the ability to produce cellulolytic enzymes such as protopectiase and cellulase.
s polymxa) and Bacillus subtilis cellulase (Bac
illus subtilis cellurase) at an appropriate ratio.

The above-mentioned microorganism is a spore-forming bacterium. In a spore state, the microorganism is particularly excellent in heat and chemical resistance and is suitable for storage.

The microorganisms are not used as they are, but the microorganisms described above are added to a mixture of water and a surfactant, a preservative, a chelating agent and a stabilizer, and used as a microorganism cleaning agent. Is set to be 1 × 10 ^{6 to} 1 × 10 ⁹ per milliliter.

The surfactant is used to make it easier for microorganisms to come into contact with the surface of an organic substance that is a substance causing dirt or odor. Non-ionic surfactants that have little effect on the activity and propagation of microorganisms are desirable. Ethoxylate alkylphenol is used, and the preservative is for preventing the growth of microorganisms other than the required microorganisms. For example, 1,2-benzisothiazoline-3-1 is used.

The chelating agent and the stabilizer are for suppressing the growth of microorganisms in the detergent and stabilizing the composition of the detergent. For example, ethylenediaminetetraacetic acid tetrasodium is used as the chelating agent, and dipropylene glycol is used as the stabilizer. And sodium hydroxide. Further, an opacifying agent and a pigment for coloring, or a fragrance may be appropriately added.

The composition of the microbial detergent is, for example, 3 to 5% of ethoxylate / alkylphenol as a surfactant, 1,2-bentizothiazoline-3-1 as a preservative, tetrasodium ethylenediaminetetraacetate as a chelating agent, and a stabilizer. 1% or less of dipropylene glycol and sodium hydroxide,
The opacifier is 0.05%, and the remainder is water. Microorganisms are added so that the total number is about 1 × 10 ^{7 in} 1 ml of these mixed solutions.

In the case of the microorganism detergent having the composition of the above-described example, the microorganism detergent is charged into a water supply tank, and the water in the tank is used to remove 1%.
Make it diluted 0 times. Specifically, in the case of a water tank with a capacity of 10 liters, which is used for ordinary households, 1 liter of a cleaning agent is added, and the presence rate of microorganisms in the water tank is about 1 × 10 ⁶ per milliliter. Use as it is.

According to the method of the present invention, the cleaning agent constructed as in the above-described example is charged into a water supply tank of a flush toilet, and a water supply tank 1 and a water supply pipe 2 as shown in FIG. , Through the toilet 3 and the drain pipe 4 to the water supply line leading to the sewage tank 5.

When a required amount of the cleaning agent is introduced into the water supply tank 1, the cleaning agent is diluted to a required concentration by the water stored in the water supply tank, and the microorganisms actively start to work. Microorganisms adhere to organic substances such as black mold in the water supply tank 1, secrete enzymes, decompose and digest organic substances, and ingest nutrients from the organic substances to become an energy source and proliferate vigorously.

More specifically, Bacillus subtilis (Bac
illus subtilis) secretes amylolytic enzymes, amylase and proteolytic proteases, to degrade starch and proteins, resulting in Bacillus lichuniformis (Bacillus lich).
eniformis) secretes lipase, which is an enzyme that decomposes animal and vegetable fats and oils, and decomposes animal and vegetable fats and oils.Furthermore, Bacillus polymia (Bac
illus polymxa) and Bacillus subtilis cellurase secrete cellulolytic enzymes such as protopectase and cellulase to degrade cellulose. In addition, the odor caused by the organic matter is also removed by decomposing and digesting the organic matter.

The microorganisms used in the present invention are electrically coupled to and adhere to organic substances. Specifically, the microorganism is negative (-)
The organic matter is positively charged (+), and the microorganisms and the organic matter are electrically coupled. Therefore, once the microorganisms adhere to the organic matter, they cannot be separated from the organic matter even in running water. Almost no organic matter remains in the water supply tank while adhering to the organic matter, and the organic matter is surely decomposed and digested until there is no more organic matter in the tank.

Water tank 1 by using flush toilet
When the stored water flows out of the tank, the microorganisms that have not adhered to the organic matter in the water supply tank are collected together with the stored water into the inflow pipe 2, the toilet 3,
The water is sent to the wastewater tank 5 through the drain pipe 4.

The microorganisms are supplied to the inflow pipe 2, the toilet 3 and the drain pipe 4.
Adheres to the organic matter during the flow of the water, and decomposes and digests the organic matter in the inflow pipe 2, the toilet bowl 3, and the drain pipe 4 in the same manner as the microorganisms in the water supply tank 1 described above.

In particular, since microorganisms flow along with the washing water in the toilet 3, the cleaning tools such as the inside of the water supply port and the brush, which could not be applied with the cleaning agent by the conventional cleaning method in which the cleaning agent was directly applied to the toilet, could not reach. The part at the back of the drain port that was not present can also be washed.

Furthermore, the microorganisms flowing into the sewage tank 5 also decompose and digest organic substances in the sewage tank. At this time, when the sewage tank is a septic tank, microorganisms can proliferate vigorously to decompose and digest organic matter, thereby preventing generation of offensive odor.

In the examples described above, Bacillus subtilis, Bacillus licheniformis, Bacillus polymxa and Bacillus subtilis cellulase were used as microorganisms. )
Are used, but only a few of these microorganisms can be used, or they can be used in place of other microorganisms that secrete the same enzyme, for example, other microorganisms that secrete other enzymes Can also be used.

[0028]

According to the method of the present invention, the microorganisms introduced into the water supply tank decompose and digest organic matter in the water supply tank, and actively activate and propagate using the organic matter as an energy source. The organic matter in the inflow pipe, the toilet bowl, and the drainpipe is decomposed, digested, and removed by flowing through the inflow pipe, the toilet, and the drainpipe, and the washing is performed reliably and for a long time until the organic matter is eliminated.

Further, since the method of the present invention does not use chemicals such as acids and alkalis, there is no danger of damaging rubber sealing materials or synthetic resin materials used for flush toilet plumbing or valves.

Furthermore, the method of the present invention does not require rubbing the toilet bowl with a cleaning tool such as a brush or the like, only by charging a required amount of microorganisms into the water supply tank, and may cause toxic gas to the human body. No, simple and secure.

Since microorganisms also decompose and digest organic matter in the sewage tank, the function of the sewage tank is not impaired even when the sewage tank is a septic tank.
