And an alarm unit 61 for emitting an audible alarm.

The power supply unit 58 may be used by step-down rectifying the commercial AC power, or use a battery or a battery.

The supply amount of the cleaning liquid 6 depends on the size of the main water supply pipe 4a, the water pressure of the washing water, the amount of washing water supplied, the degree of dilution, and the like. For example, when diluting the cleaning liquid 6 to one hundred thousand in the washing water, if the washing water supply flow rate is '1 ton / minute, the cleaning liquid supply amount is '10 g / minute', and diluting to one thousandth. If the cleaning water supply flow rate is '1 ton / minute', the clean liquid supply will be '100 g / minute'.

Then, the electronic pump 16 is operated by the setting unit 56 and the controller 18, the operation time of the electromagnetic pump 16 is set in consideration of the quantity supplied to the main water supply pipe (4a).

The reference value at which the electronic pump 16 is operated is changed or set to a new value through the setting unit 56 connected to the controller 18, and the electronic pump 16 is set from the controller 18 by a set value or a comparison. The cleaning liquid 6 is supplied to the main water supply pipe 4a while operating periodically or aperiodically according to the output signal.

FIG. 2 is a configuration in which a flow rate sensor (or flow rate sensor) 44 connected to the controller 18 is installed in the main water supply pipe 4a so that the cleaning liquid 6 in an amount proportional to the amount of washing water supplied is automatically supplied.

In this case, the flow rate detection value (or the flow rate detection value) input to the input unit of the controller 18 is compared with the reference value preset in the controller 18 and is a value proportional to the reference value. In response to the control signal, the electronic pump 16 operates for a predetermined period of time to pump the cleaning liquid 6, and the cleaning liquid 6 is a cleaning liquid supply pipe 10 and a cleaning liquid supply pipe 10. It is dissolved in the washing water while being supplied to the main water supply pipe (4a) via the end (10a) of the. Then, the washing water in which the cleaning liquid 6 is dissolved is supplied to each toilet U.

On the other hand, anion, called vitamin in the air, is an indispensable source of life activity, changing biological tissues to alkalinity, activating physiological functions, activating overall metabolism, maintaining balance of biological functions and increasing natural healing power. .

In addition, the anion increases the synthesis of chitochrome C, a type of metabolite, promotes the metabolism of enzymes including iron (Fe), promotes the development of copper and plants, activates the cells that make up tissues, It actively promotes metabolism and strengthens vitality.

In addition, ozone (O ₃ ), which has strong oxidizing power, has about 7 times higher oxidizing power and up to 3,150 times stronger sterilizing power than chlorine, which is used for tap water disinfection. It kills up to 99.9% of tap water virus or bacteria in 0.3 ppm in 10 seconds.

In addition, ozone (O ₃ ) is not only sterilized, but also has effects such as disinfection and bleaching, which combines with odor molecules in the water to deodorize, greatly reduces turbidity, and is a secondary pollutant that is produced in the case of chlorine disinfection ( THM) and the like are not known to be produced.

Therefore, in the present invention, strong sterilization can be achieved by supplying the washing water in which ozone (O ₃ ) or ozone (O ₃ ) and anion are dissolved together with the cleaning liquid 6 to the toilet. For example, ozone (O ₃ ) and / or anions are generated in the air and then dissolved in the wash water and the anion generator 54 and / or the ozone generator 46 in a wash water source, such as a wash water tank or wash water. This can be achieved by allowing ozone generated by installation to be dissolved directly in water.

For example, it is further improved by generating ozone (O ₃ ) and / or anions having excellent oxidizing power and having sterilization, disinfection, and bleaching power, and then dissolving it in the washing water to be supplied to each toilet (U) (S). Along with the cleaning effect, anion, which is beneficial to the human body, is supplied to the toilet space, thereby improving the function.

That is, the ozone generator 46 under the control of the controller 18 and the ozone O ₃ generated from the ozone generator 46 are blown into the main water supply pipe 4a as shown in FIG. An electronic pump 48 to be dissolved in the washing water, a check valve 50 to prevent backflow of the washing water when the electronic pump 48 is not in operation, and an ozone and / or anion supply pipe 52.

The end 52a of the ozone and / or anion supply pipe 52 is preferably configured to be bent in a streamlined or curved shape as shown in FIG. 4 so as not to resist flow velocity.

In addition to the ozone generator 46 together with the anion generator 54, anionized ozone (O ₃ ) or ozonized anion is supplied into the washing water by the electron pump 48 to be dissolved, thereby improving cleaning efficiency. It can improve more.

The ozone generator 46 and the anion generator 54 are operated periodically or aperiodically by the controller 18 so that the required amount of ozone and / or anions are supplied into the washing water and dissolved.

In the anion generator 54 and the ozone generator 46, a plurality of oxygen-based active species are generated by corona discharge as air insulation is broken between the counter electrodes due to the high voltage supplied thereto, and the oxygen-based active species is atomic oxygen (O), Oxygen (O ₂ ), Oxygen ions (O ₂ +, O _2- ), Ozone (O ₃ ), etc. These are dissolved in the washing water to increase the amount of dissolved oxygen. Odor, tobacco smoke, dust and harmful gases are chemically oxidized, decomposed and removed.

In particular, ozone (O ₃ ) sterilizes bacteria and fungi in the air, and prevents parasitic reproduction and deodorization.Anions released into toilets and toilets change the tissues to weak alkalis while acting on the human body. It activates overall metabolism, balances biological function, increases natural healing power and increases the synthesis of metabolic chitochrome C. In addition, by actively promoting the metabolism of enzymes, including iron (Fe), by activating the cells constituting the living tissue to make active metabolism and to strengthen the vitality.

In addition, the washing water is soft water by the action of anion and ozone, the hydrogen ion concentration is weak alkali (pH 6.5 → 7.6), zinc, chlorine ions, iron ions, manganese, aluminum lead components, etc. This oxidation and removal prevents internal corrosion and scale of the main water supply pipe 4a and the auxiliary water supply pipe 4, and completely eliminates coliforms, bacteria, bacteria, and molds in the washing water, and decomposes and reduces organic substances. Excellent function for deodorization.

Since the ozone (O ₃ ) is strong in oxidizing power, the ozone generator 46, the electronic pump 48, the check valve 50, and the ozone supply pipe 20 are made of a material having oxidation resistance, such as synthetic resin and stainless steel. It is preferable to constitute an anion generator 54 with.

In addition, in the present invention, external air is introduced through the cover 26 that is fastened to the clean liquid container 22 to induce smooth supply of the clean liquid 6. In some cases, a check valve may be provided in the cover portion 26 so that the injected clean liquid 6 does not leak while the clean liquid container 22 is moved, or the clean liquid container 22 is installed at the installation place. Afterwards, the packing of the stopper 36 may be removed or the stopper may be slightly opened to induce air to flow into the container 22.

The frequency of use of the toilet also depends on many factors. For example, in the case of time zones, such as night or dawn, when the time of human traffic is small, or in the case of school, such as class time, test time, the use frequency of the toilet is much reduced, so it is necessary to supply a clean liquid in proportion to the washing water.

In addition, in case of rest areas, the use of toilet bowls is much higher on holidays or holidays than on weekdays, so the amount of cleansing liquid should also increase proportionally.

In the present invention, the cleaning agent may be a solid or a liquid, or a combination thereof, and the cleaning liquid 6 may be periodically supplied using the timer function of the controller. Even if the cleaning liquid 6 is periodically supplied, since the cleaning liquid is dissolved in the main water supply pipe 4a and the auxiliary water supply pipe 4, the toilet is cleaned at any time.

The cleaning liquid 6 cleans the toilet bowl, prevents corrosion and scale of the water supply pipe, and prevents the growth of bacteria and bacteria in the water supply pipe to block the source of odor, thereby creating a comfortable toilet atmosphere by a clear and fragrant direction. .

The chemical reaction also washes every corner of the toilet to prevent bacteria from propagating and to decompose and remove odor particles such as ammonia gas and sulfur gas. The property of the cleaning liquid 6 is preferably a transparent liquid rather than a powder.

In addition, the cleaning liquid container 22 is wrapped in a heat insulating material so as not to freeze in winter or by maintaining a constant temperature at a temperature of 20 ℃ ~ 30 ℃ by using a heat transfer means having a constant temperature function to prevent the winter freeze and prevent chemical reaction degradation It is preferable to configure so.

In addition, it is completely decomposed in the washing water, has clean (deodorization), deodorization, disinfection, and fragrance, and is not harmful to the human body or toilet bowl, so that various fragrances according to the user's taste can be applied, and cool in the hot season. A cool color pigment may be added to the cleaning solution 6, a warm color pigment may be added in the cold season, and the color may be different in the washing water depending on where the toilet is installed. If you're in a hospital, you may want to add color pigments that give you a sense of security.

Groundwater uses mostly surface water (groundwater) and disinfects it by periodically adding chlorine.However, if there are many organic substances in raw water, chlorine reacts with these substances to cause trihalormothan (THM). In addition, since sufficient sterilization or harmful substances are not removed, organic scales are generated in the main water supply pipe 4a and the auxiliary water supply pipe 4, odor occurs in the water, the hardness is high, the turbidity is cloudy, the water tank In case of storage in the water, especially in the summer, rotten water smells like a variety of pathogenic bacteria, such as water quality is very poor.

Therefore, in the present invention, anion and / or ozone are generated by anion generator 54 and / or ozone generator 46 in the air in which a large amount of anions and ozone (O ₃ ) are generated, and then dissolved in the washing water to wash water ( Sterilizes and deodorizes various pathogens and bacteria that are parasitic propagation in groundwater) to prevent pipe scales, and also maintains a pleasant environment by supplying absolute or insufficient anions to balance cations and anions. .

As described above, the present invention is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those of ordinary skill in the art to which the present invention belongs. It is not limited to the accompanying drawings.

As described above, the present invention installs a backflow preventing means and an electronic pump in the cleaning liquid supply unit to prevent the washing water from flowing back to the cleaning liquid supply unit, and the cleaning liquid is supplied and dissolved in the cleaning water by a predetermined amount so that the cleaning solution is automatically cleaned. This has the effect of being made.

In addition, it is possible to centralize the centralized supply of cleansing liquid in one main water supply line, so maintenance is easy, labor and cost are greatly reduced, and the toilet toilet can be kept clean and hygienic at all times, creating a comfortable toilet atmosphere. There is.

In addition, as the amount of clean liquid is supplied in proportion to the supply flow, not only the uniform cleanness is achieved, but also the cleanliness of the toilet can be increased, and the clean liquid can be resupplyed and replenished by refilling / replacing. It can be environmentally friendly.

In addition, the present invention provides that the clean water and / or ozone and / or anions are supplied at a constant pressure by the electronic pump, and dissolved in each of them. When the operation of the electronic pump is stopped, the backflow of the washing water is prevented by closing the flow path of the check valve. There is an effect that is prevented.

In addition, in the case of using ozone and / or anion, the toilet cleaning water is cleansed by the anion and / or ozone, sterilizes bacteria and pathogens, and the washing water is bubbled with anion and / or ozone, so that chlorine disinfection is not necessary.
