As described above, the hand sterilizer 100 ′ according to the present invention generates disinfectant water using tap water which can be easily secured in the surroundings, and since the tap water includes hydroxyl and chlorine ion having sterilization and disinfectant properties, the hand sterilizer 100 'applies this to produce disinfectant water instead of artificial synthetic disinfectants. Instead of tap water, brine dissolved in saline (99% or more sodium chloride) in distilled water may be used. This is described in more detail below.

The water tank 120 stores the tap water, and has a relatively large volume to store a sufficient amount of tap water.

Since the tap water may be directly connected to the water supply pipe, the water tank 120 may be omitted if necessary. However, since the hand sterilizer 100 'is typically disposed remotely from the water pipe, the hand sterilizer 100' is preferably provided with a water tank 120.

The electrolyzer 130 electrolyzes the tap water supplied from the water tank 120, and secures chlorine by decomposing tap water containing a hydroxyl group and chlorine ions using a direct current electricity. Of course, the chlorine is hydrolyzed in water to produce hypochlorous acid (HOCl), tap water containing hypochlorous acid is used as disinfection water while having sterilization and disinfection properties.

On the other hand, when the water supplied to the electrolytic cell 130 is brine, sodium hypochlorite and sodium hypochlorite are produced through the electrolytic process, and the brine containing the same is used as disinfectant water while having sterilization and disinfection properties.

As described above, the inlet groove 111 is a place where the hand is inserted, and since the disinfecting water must be discharged by the inserted hand, the outlet of the injection nozzle 160 should be disposed to face the inside of the inlet groove 111. In addition, although the arrangement position of the spray nozzle 160 has been presented to the ceiling, this is to enable the disinfectant water to be jetted and discharged by using the free-falling principle by the weight of the sterilized water without supplying a separate driving force for discharging the disinfectant water. to be. Therefore, if a separate driver such as an injector is applied, it is not necessary to limit the arrangement position of the injection nozzle 160 to the ceiling.

On the other hand, since the injection nozzle 160 is disinfecting water is discharged from the water tank 120 accommodated in the case 110, a hole for discharging the injection nozzle 160 is required, and the arrangement position is also inside the inlet groove 111. It will be limited, but since the sensor 180 only needs to check whether the hand is inserted into the inlet groove 111, the hole is not necessarily provided or the arrangement position will not be limited to the inlet groove 111.

The electrolyzer 130 generates disinfecting water containing hypochlorous acid or sodium hypochlorite and sodium hypochlorite by electrolyzing tap water or brine. Includes one or more first and second electrode plates 131a and 132a spaced apart from each other.

The first electrode plate 131a of the first electrode 131 and the second electrode plate 132a of the second electrode 132 are inserted and fixed therebetween so as to be alternately disposed. Of course, the first and second electrode plates 131a and 132a should be spaced apart from each other without being in contact with each other. For reference, in the first embodiment according to the present invention, two first electrode plates 131a and three second electrode plates 132a are used.

Meanwhile, the first electrode plate 131a of the first electrode 131 is electrically connected to the first electrode stand 131b so as to be energized by the positive electrode (or the negative electrode), and the second electrode plate (the second electrode 132) of the second electrode 132. 132a is electrically connected to the second electrode stand 132b so as to be energized with a cathode (or an anode).

As a result, when the direct current is energized to the first and second electrodes 131 and 132, tap water or salt water (hereinafter referred to as tap water) flowing around the first and second electrode plates 131a and 132a is electrolytically transferred to hypochlorous acid or Sodium hypochlorite and sodium hypochlorite (hereinafter referred to as hypochlorite) are produced. Here, the DC electricity supplied to the first and second electrodes 131 and 132 may be obtained by rectifying AC electricity supplied to a general household or from a separately configured DC battery. It may further include a rectifier for rectifying with electricity, in the latter case may further include a direct current battery. However, since the electric supply means for driving the electrolytic cell 130 can be variously modified, the following claims do not limit the electric supply means required for driving the electrolytic cell 130.

Subsequently, the first and second electrodes 131 and 132 are mounted in the housing 133, and the housing 133 is discharged from the inlet 134 for the inflow of tap water supplied from the water tank 120 and the discharged disinfected water. It is provided with an outlet 135 to be.
