Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ion sterilizing water generating and discharging control apparatus having an electrode switch,

The present invention relates to an ion sterilization water generation and release control apparatus, and more particularly, to an ion sterilization water generation and release control apparatus having an electrode switch capable of controlling the supply amount of water, the water temperature, and the state of water.

Generally, in order to generate ion sterilizing water, a device composed of a high-power DC supply device, a discharge electrode, and a water tank is required.

In addition, appropriate control is required depending on the supply amount of water, the temperature of water, and the state of water (concentration of basic component, etc.).

When the ion sterilization water starts to be used, there is a need for a sensor which automatically detects the ion sterilization water and starts generating ion sterilization water. Specifically, a flow sensor or a flow sensor detects the flow of water or the movement of water.

1 is a conceptual diagram for explaining a relationship between an output current and an output voltage required in a general ion sterilization water generating and emission control apparatus.

Referring to FIG. 1, the supply power must be varied according to the state of the water and the amount of water used. If the overcurrent is supplied in excess of the set value, the power supply device is damaged. To protect them.

Referring to FIG. 1, the output voltage Vout is inversely proportional to the output current Iout. The output current value indicates the maximum value Imax when the output voltage value is the minimum value Vmin and the output voltage value is the maximum value Vmax when the reference voltage Vr and the reference current Iref are the center. The output current value represents the minimum value (Imin), so that the supply current can be adjusted.

The conventional ion sterilizing water generation and emission control apparatus will be described with reference to Fig. 2, and its constitution and operation will be described.

2 is a block diagram of an ion sterilization water generation and emission control device by a constant current circuit using a commonly used DDC (DC-DC Converter) 20 circuit.

The configuration and operation of the ion sterilizing water generation and emission control device by the constant current circuit using the DDC (DC-DC Converter) circuit 20 conventionally used with reference to FIG. 2 will be described.

(AC100-240V) supplied from the AC power source 10 is converted into a DC having a voltage higher than the maximum value of the discharge voltage through the ADC (AC-DC Converter) 10. [

The DC converted through the ADC (AC-DC Converter) 10 is converted into driving power of the discharge cell 30 through switching or linear DC-DC converter 20 .

At this time, a discharge current flowing to the discharge cell 30 is sensed and fed back to the DDC (DC-DC Converter) 20 for constant current control.

Thus, many SMPS PWM control ICs for DC-DC conversion have already been implemented, and they are automatically adjusted within the maximum power amount that can be supplied normally.

A typical power supply apparatus is a finite apparatus in which a maximum current is supplied at a minimum voltage and a supply power at which a minimum current is supplied at a maximum voltage. Therefore, in order to supply the supply current constantly, a problem arises in that a sensing device for measuring the amount of supplied current and a device for regulating the supplied current are required.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an ion sterilizing water generating and generating apparatus having an electrode switch that implements current setting and current sensing in a separate apparatus, And to provide a discharge control device.

Another object of the present invention is to provide an ion sterilizing water generating apparatus having an electrode switch having a manual adjusting function for manually adjusting the current amount so that the current amount does not change even when the overcurrent is supplied in the case of automatically adjusting the current setting and the current sensing, And to provide a discharge control device.

An ion sterilizing water generation and release control apparatus having an electrode switch according to an embodiment of the present invention can be achieved with the following arrangement.

According to the embodiment of the present invention, the following effects can be realized.

First, the present invention realizes the effect of providing an ion sterilizing water generation and emission control device having an electrode switch that implements the current setting and the current sensing in a separate device so that the adjustment can be made externally.

Second, there is provided an ion sterilizing water generation and emission control device having an electrode switching device having a manual adjustment function for manually adjusting the current amount so that the current amount does not change even when the overcurrent is supplied in the case of automatically adjusting the current setting and the current sensing Effect.
