Also, to "include" an element means that it may include other elements, rather than excluding other elements, unless specifically stated otherwise.

1 is a block diagram showing a sterilizing water according to an embodiment of the present invention.

Referring to Figure 1, the sterilizing water according to an embodiment of the present invention may include an electrode 10, the electrolysis circuit unit 20 and the control unit 30.

Hereinafter, with reference to Figure 1 will be described sterilizing water according to an embodiment of the present invention.

The electrode 10 may be discharged at an applied voltage to electrolyze the water provided. The electrode 10 may include a plurality of electrodes 10, and the electrode may be classified into a positive electrode and a negative electrode.

Here, the positive electrode is preferably made of an alloy of IrO2 and Ta as a material, and the negative electrode is preferably made of stainless steel (SUS). In addition, the distance between the positive electrode and the negative electrode is preferably 3 to 7mm, more preferably 5mm.

When a predetermined voltage is applied to the electrode 10, the water present around the electrode 10 is electrolyzed to remove chlorine ions (Cl-), ozone (O3), hydrogen peroxide (H202), hypochlorous acid (HClO), and hydroxyl groups. Sterilizing water containing an oxidizing agent such as (OH-) can be produced. Therefore, the object may be disinfected using the oxidation, reduction, and neutralization reaction of the generated sterilized water, or organic matter such as bacteria that may be present in the object may be removed.

As shown in Figure 1, the sterilizing water according to an embodiment of the present invention is filled in a separate tank (1), for example, a plastic bowl (bowl) or a sink of the sink, the water tank (1) The sterilized water can be made by applying a voltage to the electrode 10 immersed in the). In addition, the sterilizing water may be included in the water tank 1 itself, in this case, it is possible to generate the sterilizing water by placing the electrode 10 inside the water tank (1). Therefore, the object can be sterilized or disinfected by putting an object such as fruit or tableware into the generated sterilized water, or the sterilized water can be sterilized and disinfected by spraying the sterilized water where necessary by placing the sterilized water in a sprayer or the like.

The electrolysis circuit unit 20 may apply a voltage to the electrode 10 according to a control signal and measure the magnitude of the electrolysis current flowing from the electrode 10.

The electrolysis circuit unit 20 is directly connected to the electrode 10 and may apply a voltage to the electrode 10 according to a control signal transmitted from the control unit 30. Electrolysis may be performed at the electrode 10 by a voltage applied to the electrode 10.

When a voltage is applied to the electrode 10, ions existing in the water move to the electrode 10 by electrical attraction. In this case, the anion may provide electrons to the positive electrode, and the cation may receive electrons from the negative electrode. This can be seen that the electrons entering the positive electrode eventually escaped to the negative electrode, so that the current flows into the electrode 10. This is called the electrolysis current.

Therefore, the electrolysis current may be determined according to the amount of ions present in the water, that is, the amount of total dissolved solids (TDS), and the higher the concentration of the TDS, the more electrolysis current may occur. have.

Like the salpin bar, when the TDS concentration is high, an overcurrent may flow, causing problems such as damage to components inside the sterilizer. In order to prevent this, the electrolytic circuit unit 20 may determine whether the overcurrent is generated by measuring the magnitude of the electrolytic current flowing from the electrode 10.

Herein, the electrolysis circuit unit 20 feeds back the control voltage to the control unit 30 by a transistor whose ON / OFF is controlled according to the input of the control signal and a feedback voltage applied by the electrolysis current flowing when the transistor is turned on. The feedback unit may further include.

A detailed configuration of the electrolysis circuit unit 20 will be described in detail with reference to FIG. 2.

The controller 30 may reduce the magnitude of the electrolysis current by adjusting the control signal when the magnitude of the measured electrolysis current is greater than or equal to a reference current value.

The controller 30 may transmit a control signal to the electrolysis circuit unit 20 so that electrolysis occurs at the electrode 10. However, since the magnitude of the electrolysis current generated by the electrolysis should be maintained below the reference current value, it is possible to determine whether to transmit the control signal by continuously comparing the magnitude of the electrolysis current with the reference current value. .

Here, when the magnitude of the electrolysis current is greater than or equal to the reference current value, the controller 30 may reduce the amount of electrolysis at the electrode 10 by reducing the duty ratio of the control signal input to the electrolysis circuit. Therefore, the magnitude of the electrolysis current can be reduced.

More specifically, the controller 30 may calculate the magnitude of the electrolysis current by using the feedback voltage input from the electrolysis circuit unit 20, and base the transistor according to the calculated magnitude of the electrolysis current. The duty ratio of the control signal applied to the negative portion can be reduced.

The longer the transistor is turned on, the greater the amount of electrolysis generated by the electrode 10, and the control signal may determine whether the transistor is on or off. Accordingly, the amount of electrolysis can be set by adjusting the duty ratio of the control signal, thereby controlling the magnitude of the electrolysis current.

Figure 2 is a circuit diagram showing an electrolytic circuit portion of the sterilizing water according to an embodiment of the present invention.

Referring to FIG. 2, the electrolytic circuit unit 20 includes a connector 21, a diode D, a transistor Q, a plurality of resistors R1 to R4, a plurality of capacitors C1 to C3, and an input terminal EW. ) And an output terminal EW_FB.

Hereinafter, the operation of the electrolysis circuit unit 20 and the control unit 30 will be described with reference to FIG. 2.

When the controller 30 applies a control signal through the input terminal EW, the control signal may be input to the base terminal B of the transistor Q via the resistor R1. When the control signal is input, the transistor Q is turned on to receive the power supply voltage VCC through the electrode 10 connected to the connector 21. In this case, the electrode 10 may perform electrolysis using the power supply voltage.

Since the transistor Q is turned on by the control signal, current may flow from the collector terminal C of the transistor Q to the emitter terminal E, and an electrolysis current may flow due to the electrolysis. have. In this case, when the electrolysis current is excessively large, an overcurrent flows through the transistor Q, which may damage the transistor Q.

Therefore, in order to measure the magnitude of the electrolysis current, a feedback voltage may be applied to the controller 30 using a feedback unit. Specifically, the electrolysis current may be distributed between the resistors R2 and the parallel resistors R3 and R4 and applied to the resistors R2. The voltage applied to the resistor R2 may be a feedback voltage input to the output terminal EW_FB. The feedback voltage is fed back to the controller 30 so that the controller 30 can determine the magnitude of the electrolysis current flowing through the transistor Q and can determine whether an overcurrent flows into the transistor Q. . That is, the configuration of the resistors R2 to R4 can be seen as the feedback unit.

If the TDS concentration in the electrolyzed water is not high, the magnitude of the electrolysis current will be measured to be less than the reference current, thereby reducing the duty ratio of the control signal applied from the controller 30 to the transistor Q. Control may not be performed.

On the other hand, when the TDS concentration is high, the magnitude of the electrolysis current flowing through the transistor Q flows above the reference current, and accordingly, the magnitude of the feedback voltage inputted to the controller 30 increases due to voltage division. Done. Accordingly, the controller 30 may recognize that an overcurrent flows into the transistor Q and reduce the duty ratio of the control signal in order to prevent the transistor Q from being damaged. That is, by reducing the time for applying the voltage to the electrode 10 it is possible to reduce the amount of electrolysis at the electrode 10, thereby reducing the magnitude of the electrolysis current.

Figure 3 is a flow chart showing a method for controlling electrolysis of the sterilizing water according to an embodiment of the present invention.

3, the electrolysis control method according to an embodiment of the present invention may include an electrolysis step (S10), an electrolysis current measurement step (S20) and an overcurrent control step (S30).

Hereinafter, an electrolysis control method according to an embodiment of the present invention will be described with reference to FIG. 3.

In the electrolysis step (S10), the water provided by discharging at the electrode may be electrolyzed. As described above, when the control signal is applied by the controller, the transistor may be turned on, and when the transistor is turned on, a power supply voltage may be applied to the electrode. Accordingly, the electrolysis may be performed at the electrode by discharging the applied power voltage.

By the electrolysis, sterilized water containing oxidizing agents such as chlorine ion (Cl-), ozone (O3), hydrogen peroxide (H202), hypochlorous acid (HClO), hydroxyl group (OH-), and the like can be produced. Oxidation, reduction, and neutralization of the sterilized water may be used to disinfect the object or remove organic substances such as bacteria that may be present in the object.

Electrolysis current measuring step (S20), it is possible to measure the magnitude of the electrolysis current flowing into the electrode by the electrolysis.

When the electrolysis is performed, current may flow into the electrode by the ions present in the water, which may be referred to as an electrolysis current. The size of the electrolysis current may be determined according to the amount of ions present in the water, that is, the amount of total dissolved solids (TDS), and the higher the concentration of the TDS, the more electrolysis current may occur. have.

However, if the electrolysis current is excessively generated, the internal parts of the sterilizer may be damaged, so it is necessary to control the electrolysis current so that it does not occur above the reference current. To this end, the electrolysis current measuring step (S20) may measure the magnitude of the electrolysis current generated by the electrolysis.

Specifically, the feedback unit may transmit a feedback voltage due to the electrolysis current to the controller, and the controller may calculate the magnitude of the electrolysis current from the feedback voltage.

In the overcurrent control step S30, if the measured magnitude of the electrolysis current is equal to or greater than a reference current value, the magnitude of the electrolysis current may be reduced by adjusting the control signal. In detail, the magnitude of the electrolysis current may be reduced by reducing the duty ratio of the control signal input to the electrolysis circuit unit.

The control signal may be to control the on or off of the transistor, and whether the power voltage is applied to the electrode may be determined according to the on or off of the transistor. Since the electrolysis may occur when the power supply voltage is applied to the electrode, the electrolysis amount may be determined according to the input time of the control signal, and thus the magnitude of the electrolysis current may be determined.

Therefore, in the overcurrent control step (S30), the amount of electrolysis and the amount of electrolysis current can be determined by adjusting the duty ratio of the control signal, and if the magnitude of the electrolysis current is greater than or equal to a reference current value, the control signal. It is possible to reduce the magnitude of the electrolysis current by reducing the duty ratio of.

The present invention is not limited by the above-described embodiment and the accompanying drawings. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims, .
