Bidet utilized in the present invention is a commercial bidet of the general type to wash the anal area and vagina by being sprayed in a pressurized state through the injection nozzle 100, the water supplied through the water tank or pipe.

The injection nozzle 100 has a cylindrical nozzle body 110, the ultraviolet lamp is arranged in a floating direction in the longitudinal direction.

In addition, inside the nozzle body 110, the first and second inlets 101 and 103 and the first and second outlets 105 and 107 through which the washing water flows are spaced apart from each other to protrude.

In addition, the spray nozzle 100 is configured to spray the washing water separately to the bidet water (first nozzle) and the washing water (second nozzle) while moving around the ultraviolet lamp 120 by two minutes.

According to the present invention, the first solenoid valve 50 is opened by the operation signal of the controller 40, and the washing water supplied through the water tank or the pipe is sprayed in a pressurized state through the injection nozzle 100, thereby cleaning the anal area and the vagina. In this possible, the connection line 2 is formed to be connected to the pipe line 1 through which the washing water is supplied through the water tank 30 or the pipe by the operation of the first solenoid valve 50.

In addition, the first and second discharge ports 105 and 107 of the injection nozzle 100 have the internal space of the ultraviolet lamp 120 and the nozzle body 110 except for the ultraviolet lamp 120 in the internal space of the nozzle body 110. In communication with the first and second outlets 105 and 107 individually by first and second protruding blocks 111 and 113 for arranging and dividing the surrounding space partitioned by a wall into two centers. The first and second communication ports (H, S) are divided into, the first and second communication port by arranging the first and second discharge port 105 and the second discharge port by spaced apart from each other via the partition 112 at the end. 107 is configured to open upward in the same direction.

The inner wall of the nozzle body 110 and the first and second protruding blocks 111 and 113 are coated with titanium dioxide.

In other words, an ultraviolet lamp 120 for irradiating ultraviolet rays is arranged concentrically inside the nozzle body 110, and is divided into two parts above and below the ultraviolet lamp 120.

In addition, the nozzle body 110, along with the concentrically arranged ultraviolet lamp 120, the washing water flowing through the connection line 2 is sterilized and sprayed while passing through the two divided spaces of the ultraviolet lamp 120 It is a structure provided with a nozzle part.

In addition, the nozzle body 110 and the first and second protruding blocks 111 and 113 dividing the ultraviolet lamp 120 up and down two are made of Pyrex material so that the ultraviolet lamp 120 is connected to the nozzle body 110. It is configured to float concentrically. Of course, the nozzle body 110 may employ a transparent tube made of quartz or glass in addition to the aforementioned Pyrex.

In addition, the nozzle body 110 is provided with a seal member 130 for sealing the front and rear ends of the cylindrical nozzle body 110, the cap member 140 on the outside of the seal member 130 is the nozzle body It is fitted to seal the rear end of 110.

At this time, the operation of the ultraviolet lamp 120 is linked to the opening and closing of the first solenoid valve 50 at the same time.

At this time, the washing water passing through the ultraviolet lamp 120 can be selected by the selection key of the controller 40 so that the user can arbitrarily select and operate the operating method of sterilization washing and sterilization drying by ultraviolet light. It is.

In addition, the ultraviolet lamp 120 is discharged through the injection nozzle 100 while the second and third solenoid valves 51 and 53 are selectively opened when the user operates the selection key of the controller 40 for use. The bidet water and the washing water are separated into a simple configuration and are sprayed individually.

Therefore, the bidet water and the washing water are to be completely sterilized washing water through the injection nozzle 100 just before the final spraying step.

According to the characteristics of the sterilization accordingly, fungi, harmful bacteria and viruses are completely removed.

In the present invention, the nozzle body 110 coated with titanium dioxide is most suitable for a Pyrex tube because the wavelength range of light transmitted along the tube is different. Quartz transmits light of about 252nm, which is suitable for sterilization using short wavelengths, and glass transmits light of about 400nm. Pyrex, on the other hand, transmits light in the 315-450 nm region.

The gel-sol method is used as a method of coating titanium dioxide used as a photocatalyst in the washing water sterilization method according to the present invention on the inner wall of the nozzle body 110.

This method is a coating treatment method in which the nozzle body 110 is immersed in the sol-like solution of the inorganic powder to be coated on the inner wall surface of the nozzle body 110, and then the nozzle body 110 is taken out and heat-treated and gelled by a constant tensile velocity. to be. It is important to prevent gelation of the sol liquid when the inorganic powder is coated on the nozzle body 110 by using such a treatment method. In the conventional coating treatment of titanium dioxide, a nitric acid solution is used as the gelling inhibitor. As a result, gelation proceeds and there is a problem in that the sol solution cannot be repeatedly used. Accordingly, in the present invention, titanium tetrachloride was first used as an antigelling agent to additionally prevent the gelation by additionally adding emyl acetone acetate.

The method of coating titanium dioxide on the nozzle body 110 in detail will be described below in detail.

[Production of Sol Solution of Titanium Dioxide]

Titanium-isopropylate (Ti [OCH (CH3) 2] 4) is dissolved in ethanol and then titanium tetrachloride (TiCl4) is added thereto to prevent gelation of the solution. Ethyl acetone acetate is added to this as an anti-gelling agent and the mixture is sufficiently stirred, followed by stirring with ethanol and water gradually added to obtain a clear sol solution.

Add ethylene glycol if the solution is less transparent or if you want to preserve the solution for a long time.

[Titanium Dioxide Coating]

The nozzle body 110 to be coated is washed well with acetone, and then dried and soaked in a titanium dioxide sol solution, and then the tensile velocity is adjusted to 7 to 13 cm / min to be stretched over the water surface. At this time, the coating thickness of titanium dioxide is 85 to 140 nm. In order to make the coating thicker than this, the coating treatment and the heat treatment process were repeated two or three times after the heat treatment process after the coating treatment, thereby forming a double multilayer film to increase the coating thickness. The coating thickness of titanium dioxide was measured using an indirect measurement method by optical interference using a refractive index difference using an Elso-meter model Auto EL-II (manufactured by Rudolph, USA).

[Heat treatment [gelation of titanium dioxide]]

As described above, the nozzle body 110 coated with titanium dioxide is naturally dried at room temperature for 3 hours or more, and then heat-treated at 300 ° C to 500 ° C. At this time, the organic substances contained in the coating are incinerated and removed. The nozzle body 110 heat-treated in this manner is used after cooling to room temperature.

The Parylene tube coated with titanium dioxide prepared according to the production method of the present invention can transmit light of 320 nm to 12 μm, and thus can effectively use light of UV 315 to 450 nm effective for photoreaction by titanium dioxide. have. Therefore, it is possible to increase the efficiency of light, thereby increasing the sterilization effect. This effect is confirmed through the following examples.

Example 1

After dissolving 568.5 g of titanium-isopropylate (TIPT) in 737.1 g of ethanol, 64.5 g of titanium tetrachloride and 130 g of ethyl acetone acetate were added thereto, followed by sufficient stirring. To the obtained sol solution, a mixed solution of 1105.7 g of ethanol and 144 g of water was added and stirred sufficiently to obtain a transparent sol-like titanium dioxide solution.

On the other hand, the nozzle body 110 was washed well with acetone and dried. The nozzle body 110 was immersed in the transparent sol solution and then pulled up at a speed of 13 cm / min. This was naturally dried at room temperature for 3 hours and then heat treated at 400 ° C. for 2 hours to obtain a nozzle body 110 coated with titanium dioxide having a thickness of 140 nm.

The nozzle body 110 coated with titanium dioxide thus prepared was arranged in parallel, and an ultraviolet light was installed inside the nozzle body 110 to sterilize the aqueous solution by contacting it while shining light.

[Example 2]

The Pyrex plate was washed well with acetone and then immersed in the solution of the titanium dioxide sol phase prepared in Example 1, followed by pulling up at a speed of 13 cm / min. This was naturally dried at room temperature for 3 hours and then heat-treated at 400 ° C. for 2 hours to obtain a Pyrex plate coated with titanium dioxide having a thickness of 140 nm.

Thus, a plurality of Pyrex plates manufactured in this way were made cylindrical, and the ultraviolet lamp 120 was installed on the cylindrical nozzle body 110, and the light was oxidized, decomposed, and sterilized by passing through the wash water.

As a test example, the treated wash water was decomposed, oxidized and sterilized for 3 seconds by passing through the connecting tank at a flow rate of 1 l / min, and one was not oxidized, decomposed and sterilized as a control. At this time, the temperature of the treated water was 19 ℃ before treatment, 19.2 ℃ after treatment.

At this time, the number of bacteria was determined to be almost dead after the number of cells after incubation for 30 days at 30 ℃ by applying to the following Endo medium, YM medium, Neutrient medium.

Therefore, the sterilization method is much superior to the sterilization method performed by the previous UV lamp, and by combining with a bidet it is possible to derive a very excellent effect such as to improve the quality of the wash water at all times.

As a result of the above experiment, the spray water through the nozzle is to be completely sterilized wash water. As a result, the sterilization effect of the washed portion is further enhanced, and the sterilizing power is also effective to remove odors caused by microorganisms.
