As shown in FIG. 1 (a perspective view showing the appearance of a hand sterilizer), the hand sterilizer 100 forms an inlet groove 111 through which the front surface is opened so as to accommodate the hand, and is fixed to a wall or installed on the floor. The retracting groove 111 is provided with a sensor for detecting that the hand is inserted, and when the insertion of the hand is detected through the sensor, a spray nozzle 160 (see FIG. 2) for discharging the disinfectant for hand disinfection is disposed. As a result, when the user puts his hand into the inlet groove 111, the sensor detects this to operate the hand sanitizer 100, and eventually the disinfectant is sprayed from the spray nozzle 160 to disinfect the hand.

On the other hand, the conventional hand sterilizer 100 uses a disinfectant artificially synthesized for hand disinfection as described above. These disinfectants have the condition that even after frequent use, they have little side effects on the skin and can be easily obtained and used. Therefore, conventionally, an alcohol disinfecting agent satisfying the above-described conditions as a disinfectant of the hand sterilizer 100 has been widely used.

However, the disinfectant made of alcohol-based disinfectant may also cause side effects of drying the skin due to frequent use, and it is difficult to refill the used disinfectant because it is relatively easy to obtain disinfectant. In addition, there is a difficulty in utilizing the conventional hand sterilizer 100 in the general home because the economic burden is accompanied to secure the disinfectant.

As a result, the conventional hand sterilizer 100 using an artificial disinfectant has a burden on frequent use due to the above-described problems, and there is a problem that its use is extremely limited.

Accordingly, the present invention has been made to solve the above problems, can be easily used in ordinary home or daily life, less burden due to management and maintenance and use, and to provide a hand sanitizer that can minimize side effects It is a technical problem.

It is a hand sterilizer that includes.

In the above invention, since it is possible to produce and supply a large amount of disinfectant water for hand disinfection by electrolyzing tap water which can be easily secured in the surroundings, it is possible to reduce the economic burden of consuming disinfectant water, and also significantly reduce side effects of the skin. It can be widely distributed and utilized in general homes or public places, and it can be used to improve the health of the public by making it a habit to keep the hands clean.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the appearance of a hand sterilizer, Figure 2 is a cross-sectional view schematically showing the appearance of a hand sterilizer according to the present invention, Figure 3 is a block diagram showing the configuration of the hand sterilizer according to the present invention, This will be described with reference.

The hand sterilizer 100 ′ according to the present invention uses disinfectant water having a disinfecting function generated by electrolyzing tap water as a disinfectant for hand disinfection.

The hand sterilizer 100 ′ according to the present invention includes a water tank 120 for storing tap water, an electrolytic cell 130 for electrolyzing tap water supplied from the water tank 120, and a disinfectant water generated by the electrolytic cell 130 forcibly moved. The user manipulates the pump 140, the spray nozzle 160 through which the disinfectant is discharged, the control module 150 for controlling the operation of the electrolytic cell 130 and the pump 140, and the control form of the control module 150. Terminal module 170, a sensor for detecting the insertion of a hand into the retracting groove 111, a water tank 120, an electrolytic bath 130, a pump 140, a spray nozzle 160 and a control module And a case 110 having an inlet groove 111 formed to enable the hand to be drawn in while enclosing and protecting the 150, the terminal module 170, and the sensor.

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), the tap water containing hypochlorous acid is used as sterilization 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.

FIG. 4 is a perspective view illustrating an electrode body of an electrolytic cell according to the present invention, and FIG. 5 is a cross-sectional view illustrating a first embodiment of an electrolytic cell to which the electrode body shown in FIG. 4 is applied.

The case 110 is manufactured to have a hollow shape having a hollow, and has an inlet groove 111 into which a hand can be inserted. On the other hand, it is preferable that the back surface is a flat surface to be fixed in close contact with the flat wall surface, the shape can be variously modified according to the installation site, of course.

Subsequently, a hole (not drawn out) in which the sensor and the injection nozzle 160 are disposed is formed in the ceiling of the inlet groove 111. 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 only needs to check whether the hand is inserted into the retracting groove 111, the hole is not necessarily provided or the arrangement position will not be limited to the retracting groove 111.

The electrolyzer 130 generates disinfecting water containing hypochlorite or sodium hypochlorite and sodium hypochlorite by electrolyzing tap water or brine, and the first and second electrodes 131 and 132 which are direct current electrodes to increase electrolytic efficiency. Includes one or more first and second electrode plates 131a and 132a spaced apart from each other.

That is, as illustrated in FIGS. 4 and 5, a plurality of first and second electrode plates 131a and 132a constituting the first and second electrodes 131 and 132 are arranged to be spaced apart from each other and thus formed. 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.

It is preferable that the first and second electrode plates 131a and 132a according to the present invention have a mesh shape so that they can move through the first and second electrode plates 131a and 132a in the process of tap water. This is to allow the tap water introduced into the electrolytic cell 130 to move smoothly in a narrow space in which the plurality of first and second electrode plates 131a and 132a are dense, and the tap water introduced into the inlet 134 is not interfered with by any means. It easily flows out of the outlet 135.

The water tank 120 of the hand sterilizer 100 'according to the present invention is disposed lower than the position of the injection nozzle 160, as shown in Figure 2, the electrolytic cell 130 is disposed below the water tank 120, Tap water stored in the tank 120 flows naturally into the electrolytic bath (130). That is, the tap water stored in the water tank 120 flows into the electrolytic cell 130 located below, and electrolysis is performed in the electrolytic cell 130 without a separate driving source.

The pump 140 provides a driving force for forcibly pulling up the disinfecting water located in the electrolytic cell 130 to the injection nozzle 160, forcibly disinfecting water from the electrolytic cell 130 at a lower position than the injection nozzle 160. If pumpable means, various modifications may be made without departing from the scope of the following claims.

On the other hand, since the amount of disinfectant water to be pumped by the pump 140 is the entire disinfectant water temporarily generated in the electrolytic cell 130, the driving force of the pump 140 pumps about 1 to 3 cc of toxic water, which is the capacity of the electrolytic cell 130. The driving force that you can do will be enough.

The injection nozzle 160 is an outlet through which the disinfectant water pumped by the pump 140 is forcibly discharged, and is manufactured in the form of a nozzle to increase the spraying effect of the disinfectant water.

For reference, a hose (H) is provided to guide the disinfectant water flowing out of the electrolytic cell 130 to the injection nozzle 160 by the driving force of the pump 140, and for this purpose, one end of the hose H is provided in the electrolytic cell 130. It is connected to the outlet 135 and the other end is connected to the injection nozzle 160.

The sensor detects the inflow of the hand into the inlet groove 111 and transmits the corresponding detection signal to the control module 150. On the other hand, since the sensor only needs to detect the inflow of the hand embodiment of the sensing means will vary. The sensor according to the present invention may be applied to an infrared sensor, a thermal sensor, a motion sensor.

The control module 150 receives the detection signal transmitted from the sensor and drives the pump 140 and the electrolytic cell 130 to control the disinfecting water from the spray nozzle 160 to be discharged into the inlet groove 111. On the other hand, the control module 150 may be controlled ON / OFF by the switch (S) disposed outside the case 110, the ON / OFF of the control module 150 is ON / OFF of the entire hand sterilizer (100 '). Will be OFF.

The terminal module 170 includes an output means for outputting an operating state of the hand sterilizer 100 'and an input means manipulated by a user to control the hand sterilizer 100', and the control module 150 While communicating with the user to enable the user to actively check the operation and control of the control module 150.

On the other hand, the output means and the input means may be implemented in various forms. For example, the output means may be a lamp that is simply ON / OFF, may be a 7-segment, may be a liquid crystal monitor. In addition, the input means may be a simple button or a touch screen.

An embodiment of the hand sterilizer 100 ′ according to the present invention having the above-described configuration will be described sequentially according to the operation process.

(1) Fill the brine dissolved salt in the water tank 120. At this time, the salt water is 2kg of salt dissolved in 10L of distilled water.

(2) When the user inserts a hand into the inlet groove 111 for hand disinfection, the sensor detects a hand and transmits a corresponding detection signal to the control module 150.

(3) The control module 150 receives the detection signal and transmits a driving signal to the electrolytic cell 130 and the pump 140. In this case, the driving signal may be to operate the electrolytic cell 130 and the pump 140 at the same time, it may be a time difference to the operation of the electrolytic cell 130 and the pump 140.

(4) The electrolytic cell 130 receiving the driving signal conducts DC electricity to the first and second electrodes 131 and 132 to electrolyze the tap water located in the electrolytic cell 130. As described above, since the electrolytic cell 130 located below the water tank 120 is always filled with tap water introduced from the water tank 120, the electrolytic cell 130 is electrolyzed as it is when the electrolytic cell 130 is energized to generate hypochlorous acid having bactericidal properties.

Here, the first and second electrodes 131 and 132 are made of platinum and titanium.

Meanwhile, the pump 140 receiving the driving signal forcibly pulls up the disinfecting water in the electrolytic cell 130 and guides it to the injection nozzle 160.

(6) The disinfectant water drawn by the driving force of the pump 140 is injected through the injection nozzle 160 is discharged by the hand inserted into the inlet groove 111.

(7) The control module 150 transmits an output signal to the terminal module 170 so that the user can check the operation state of the hand sanitizer 100 '. In addition, the user may operate the terminal module 170 to adjust the control contents of the control module 150.

6 is a cross-sectional view showing a second embodiment of the electrolytic cell according to the present invention, Figure 7 is a perspective view showing the electrolytic cell shown in Figure 6, it will be described with reference to this.

In the second embodiment of the electrolytic cell 130 'according to the present invention, the first and second electrode plates 131a' and 132a have two first electrode plates 131a 'and two second electrode plates 132a'. ') Is interposed between the first and second electrode plates 131b' and 132b 'which electrically connect the first and second electrode plates 131a' and 132a 'to the ends of the electrolytic cell 130'. ) To be withdrawn outside.

The first and second electrode strips 131b 'and 132b' drawn out to serve as a general plug terminal, and the mechanical and electrical connection of the electrolytic cell 130 'in the case 110 are connected to the outlet and the plug. It was made to be removable.

To this end, a supply means (not shown) for supplying direct current electricity to the electrolytic cell 130 ′ should be formed as an outlet type.

Figure 8 is a view showing a third embodiment of the hand sanitizer according to the present invention, it will be described with reference to this.

The hand sterilizer 100 ′ according to the present invention uses tap water or brine to generate electrolytic hypochlorite water (disinfectant water) having a disinfecting effect.

Tap water or brine contains the chlorine ions needed to produce hypochlorous acid, depending on the amount of hypochlorite.

By the way, the effective chlorine concentration that can sufficiently generate hypochlorous acid having sterilization and disinfection effect is in the range of several tens to hundreds of ppm, if it is out of this range sterilization and disinfection efficacy is reduced or strengthened, disinfection function or side effects on the skin May cause.

Therefore, in order to achieve optimal disinfection function, effective chlorine concentration should be maintained appropriately and this should be checked periodically.

To this end, the control module 150 of the hand sterilizer 100 'according to the present invention is a power supply 151 for supplying electricity to the first and second electrode units 131b and 132b while maintaining a constant current or a constant voltage, and a constant current or a constant voltage. Resistance checking means 152 for checking the resistance value of the tap water or the salt water in the electrolyzer 130 to which electricity is supplied, and A for converting the resistance value of the analog type confirmed by the resistance checking means 152 into a digital form. / D converter 153, and the inspection means 154 for checking the resistance value converted to the digital format, compares with the reference value and calculates the result. Here, a reference value is the concentration value of chlorine which distinguishes chlorine shortage, titration, and excess based on the concentration range of effective chlorine.

For reference, tap water or salt water filled in a predetermined capacity, such as the electrolytic cell 130, as the concentration of ions present in the tap water or brine decreases the resistance of electricity through the tap water or salt water, by applying this principle to tap water or salt water Chlorine concentration can be estimated.

The reference value input to the inspection means 154 is secured by measuring / recording each resistance while varying the chlorine concentration contained in tap water or brine based on the capacity of the electrolytic cell 130, and the inspection means 154 checks the resistance. The resistance value identified by (152) is compared with the reference value and the relevant chlorine concentration is searched.

On the other hand, in the case of brine, since there are fewer impurities in addition to chlorine and sodium ions compared to tap water, the confirmation of chlorine concentration using the above-described system will be more accurate in the case of brine than tap water.

On the other hand, the output means 171 of the terminal module 170 receives the result signal calculated by the inspection means 154 and displays the corresponding contents.

Here, the display method is divided into three stages of 'lack', 'titration' and 'excess', and the output means 171 is composed of three lamps corresponding thereto, so as to inspect according to the inspection result of the inspection means 154. Under control of the means 154, the output means 171 will light one of the lamps referring to 'lack', 'titration' and 'excess'.

As a result, the user can check the contents of the corresponding lamp is lit, it is possible to adjust the concentration of the tap water stored in the tank (120).

However, the display method of the output means 171 is not limited to the above-described embodiment, and may be variously modified within the scope of the following claims.
