The input unit 111 is directly connected to, for example, a flow sensor 120 for measuring and detecting a flow rate carried through the water pipe (not shown) to apply flow information transmitted from the flow sensor 120. do. The touch screen 102 or input keyboard has various selection modes, for example, alkaline water 1, alkaline water 2, alkaline water 3 and acidic water, and the like, and selection of these modes generates ionized water corresponding to each level. It begins.

The input unit 111 is also connected to the timer 122 for measuring the operating time of the flow sensor 120 and the temperature sensor 130 for detecting the water temperature of the ionized water to apply time and temperature information transmitted from each of them. Done. In addition, the input unit 111 is connected to the current sensor 142 for detecting the intensity of the current supplied to the electrolytic cell 140 to apply information about the current value transmitted from it.

The processing unit 112 applies a variety of data and command signals inputted through the input unit 111 to its own built-in program to perform arithmetic processing, and the first and second power supply units 151 and 152 such as a power cord or a power switch. It is directly connected to supply power to each part of the ionized water generator 100 step by step.

The output unit 113 converts the final result value calculated by the processing unit 112 into a corresponding signal that can be recognized by each component in the ionized water generator 100 and delivers the signal to each component. 113 is connected to display means 161 for presenting the final result in a visual way and / or sound output means 162 for presenting in an audible way.

And connected to each other to convert the final result value extracted from the processing unit 112 into a corresponding signal so that the inlet valve 104 and the extraction valve 105 can be recognized and transmitted. The extraction valve 105 may repeat extraction and stop of the ionized water arbitrarily by the user by operating the extraction button 106 connected to the input unit 111 irrespective of power supply or fluid flow in the ionizer generator 100.

The output unit 113 is connected to a filter replacement period indicator 170 and an electrolytic cell power supply (pulp width controlled switching regulator: PWM; 144) indicating a filter replacement time according to the flow rate measured by the flow sensor 120, respectively. As a result, the resultant value calculated by the processor 112 is converted into a corresponding signal and transmitted.

The following describes the operation of the ionized water generator according to the control structure of the present invention.

First, when a power cord is plugged into an outlet to supply power to the ionized water generator 100 and the power switch is turned on, the processing unit 112 of the controller 110 transmits this signal to each component of the ionized water generator 100. In this case, the display means 161 performs the set initial operation such as displaying the initial main screen on the screen.

When the power switch is turned on, the ionizer 100 starts electrolysis of the raw water by the electrolyzer 140 by turning on the electrolyzer power 144 by the control device 110, wherein the raw water supplied to the electrolyzer 140 is filtered.

Supplied to. At this time, the current sensor 142 detects the current value that is energized in the electrolytic cell 140 in real time and inputs it to the control device 110 through the input unit 111. When the actual current value is lower than the set value, the control is performed. The device 110 increases and applies the power supplied to the electrolytic cell 140 step by step. On the contrary, when the actual current value is higher than the set value, the device 110 lowers and applies the power step by step to induce it to approach the set current value.

On the other hand, in the control device 110, to protect the electrolytic cell 140 and the device connected thereto, the current value is not divided into the maximum value and the minimum value to set the range by the current value is performed to the electrolytic cell to the electrolytic cell. It is preferable not to.

As described above, the present invention not only facilitates operational control for ionized water extraction in the ionized water generator, but also can control the ionized water level under optimum conditions, and the lack of raw water is detected by the flow sensor so that the ionized water generator operates. Even if this is stopped, an effective display or sound output allows the user to know the cause of the operation stop for convenience in application.

In addition, the present invention can prevent the ion water extraction operation is completely stopped due to the occurrence of a minor obstacle on the flow path, and the phenomenon that the ion water extraction time is delayed when the function is switched, and by allowing the flow rate to be clear for normal operation, It is possible to prevent the product from being damaged by inflow of raw water out of range.
