Description

Bidet apparatus [0002]

The present application relates to a sanitary device, and more particularly to a bidet device having a sanitizing function.

A bidet is a type of sanitary pottery that is used to clean the genitals and the anus after the toilet. Bidet is a pottery product that contains hot water in the 16th century, and it is derived from the fact that the European nobility group sits on a horse as it rides on horseback. Bidets are said to have been invented by medieval knights on their way from the Crusades to Jerusalem, and are then used as devices for wiping the genitals and the anus afterwards, or used for medical purposes. Bidet is used to remove hot water with moderate temperature from the center of the appliance without using a hand to clean the local area smoothly and to remove hemorrhoids, cystitis, vaginitis and diarrhea caused by diarrhea. Women's menstruation and postpartum cooking It is also used in poetry. Such bidet generally uses tap water supplied from a water purification plant as cleansing water. In the tap water, chlorine may be added for sterilization or disinfection, residual chlorine may remain, and microorganisms may remain. Since the washing water supplied from the bidet comes into contact with sensitive parts of the human body, maintaining the hygienic environment is an important factor.

The first supply channel portion 215 and the second supply channel portion 240 are connected to the first connection pipe portion 220 while the second supply channel portion 240 and the nozzle portion 250 are connected to the second connection pipe portion 225 ).

A rinse water sterilizing section 260 may be provided to sterilize the rinse water located in the second supply water channel section 240 around the second supply channel section 240 or flowing through the second supply channel section 240. The washing water sterilizing unit 260 may include ultraviolet light emitting diodes (UV LEDs) 261 for irradiating ultraviolet light for sterilization, for example, ultraviolet light having a wavelength of 100 nm to 400 nm. A plurality of ultraviolet light emitting diodes 261 may be installed in the form of modules mounted on a module substrate 265. The ultraviolet light emitting diodes 261 may be installed on the upper and lower surfaces of the second supply channel section 240 in a manner that they are introduced or wrapped.

The washing water sterilizing part 260 including the ultraviolet light emitting diode 261 may be installed in a nozzle moving housing part 267 surrounding the second supply water channel part 240. The nozzle moving housing part 267 is fastened in the form of wrapping around the second supply duct part 240 and the other end is provided with a feed shaft 268 and a rotary shaft 269 of FIG. 5 for moving the feed shaft 230 . The rotation of the rotary shaft 269 causes the transport shaft 230 to move and the nozzle moving housing part 267 to move and the second supply channel part 240 fastened to the nozzle moving housing part 267 to move , The nozzle unit 250 connected to the second supply water channel unit 240 can be moved back and forth.

The ultraviolet light emitted from the washing water sterilizing unit 260 including the ultraviolet light emitting diode 261 is incident on the washing water located in the second supply water channel unit 240 to sterilize the washing water. The second supply channel portion 240 for transmitting ultraviolet light may include a tube portion of a substantially transparent material such as a quartz tube. The irradiated ultraviolet light sterilizes the washing water and can also reform the washing water to advanced oxidized water. Highly oxidized water can mean a solution containing a hydroxyl radical (OH *) with strong oxidizing power.

When tap water is used as raw water for washing water, highly oxidized water can be produced by generating hydroxide radicals (OH *) from residual chlorine by half-reacting ultraviolet rays with residual chlorine in tap water. The tap water may contain about 0.1 mg / L to 2.0 mg / L chlorine. It is also possible to generate a chlorine radical (Cl *) from residual chlorine. The highly oxidized water itself is pure water which has remained therein and has already been removed or chlorine-free to produce offensive odor. In addition, the highly oxidized water can perform a function of sterilizing microorganisms in tap water or oxidizing and decomposing antibiotic components using hydroxyl radicals.

The process of reacting residual chlorine with ultraviolet rays to generate a hydroxyl radical (OH *) can be described as follows. Chlorine added in a water purification plant for sterilization or disinfection can be present in tap water in the form of hypochlorous acid (HOCl) and hydrochloric acid (HCl) as in the reaction formula (1). Hypochlorous acid can be decomposed into hydrogen ions (H +) and hypochlorite ions (OCl-) and can be present in tap water, as in the reaction formula (2).

Cl 2 + H 2 O -> HOCl + HCl - (Scheme 1)

HOCl - > H + + OCl- - (Scheme 2)

In the equation (2), the dissociation constant (pKa) at 20? Is 7.6, indicating that hydrogen ions in hypochlorous acid are sufficiently dissociated to exist as hydrogen ions (H +) and hypochlorous acid ions . Hypochlorous acid present in tap water can be photolyzed by ultraviolet rays to generate hydroxyl radicals (OH *) and chlorine radicals (Cl *) as in the following reaction formula (3). The hypochlorite ions present in tap water can be photolyzed by ultraviolet rays to generate oxygen radicals (O * -) and chlorine radicals (Cl *) as in the reaction scheme (4). The oxygen radicals can react with water to form hydroxide radicals and hydroxide ions, as in the reaction scheme (5) below. At this time, the ultraviolet ray may have a wavelength of about 100 nm to 400 nm.

HOCl + UV - > OH * + Cl * - (Scheme 3)

OCl- + UV- > O * - + Cl * - (Scheme 4)

O * - + H2O - > OH * + OH - (Scheme 5)

The hydroxyl radicals or chlorine radicals generated through the above-described reaction formulas (3) to (5) can act as strong oxidizing agents. Further, through the above reaction formulas (1) to (5), the chlorine remaining in the tap water is removed, so that the tap water can be removed or the offensive odor can be removed. As described above, there is a high possibility that residual chlorine is present in the form of hypochlorous acid ions in tap water, and can be efficiently removed through ultraviolet irradiation.

In addition, the ultraviolet light can function to sterilize harmful microorganisms in tap water by ultraviolet rays. In addition, the ultraviolet light source can perform the function of photodissolving the antibiotic component in tap water by ultraviolet rays. As an example, the antibiotic component may comprise ibuprofen (IBF), sulfamethoxazole (SMX), ciproflaoxacin (CFX), or a combination of two or more of these. The antibiotic component may be photolyzed and removed by ultraviolet irradiation. Thus, by removing the antibiotic component, the highly oxidized water purified with cleaner water can be applied as the washing water of the bidet.
