WATER IONIZER PROVIDED WITH CURRENT TRANSFORMER TO CONTROL OPERATION CURRENT OF ELECTROLYTIC CELL}

The present invention relates to a water purifier, and more particularly, a current transformer (CT) is attached to a secondary side of an electrolytic cell transformer used for electrolysis in an ion water purifier equipped with an electrolytic cell, so that the current of the electrolytic cell transformer during the operation of the electrolytic cell is fixed. It detects and converts it into a voltage that can be read by MICOM, and then monitors the electrolytic cell operating current feedback port during electrolytic cell operation. When it exceeds the preset current value, it operates with the current value set forcibly to protect the electrolytic cell. The present invention relates to an ion water purifier having a function of returning to a value set in a product when an electrolytic cell operating current value is detected at a normal level.

The water purifier is divided into a cold / hot water purifier that filters and purifies water using a filter, and an ion purifier that electrolyzes water using an electrolytic cell.

The electrolytic cell used in the conventional water purifier uses ferrite and sten tubes to electrically decompose water supplied from a tap water in a container of a predetermined size to form acidic water used for washing and alkaline water used for drinking. And a diaphragm that has an osmotic membrane between the ferrite and the sten tube.The ferrite is connected to an anode wire and ionized with acidic water, and the sten tube is connected to a cathode ray to ionize the supplied water with alkaline water. Equipped with.

Such a conventional ion purifier does not detect the operating current of the electrolytic cell, so if the electrolytic cell overcurrent occurs, the electrolytic cell has a fragility that can be leaked due to breakage of the electrolytic cell due to overheating of the electrolytic cell or the electrolytic cell. There is a problem in that a circuit that senses current at an electrode or a port of an electrode has a vulnerability that cannot receive an accurate feedback of the operation of the electrolyzer.

The present invention was created to solve the above problems, the present invention is attached to the current transformer (CT; current transformer) on the secondary side of the electrolytic cell transformer used for the purpose of electrolysis to detect the current of the electrolytic cell transformer during electrolytic cell operation After converting to voltage that can be read by MICOM, monitor the electrolytic cell operating current feedback port during electrolytic cell operation.If it exceeds the preset current value, it operates with the current value set forcibly to protect the electrolytic cell. When the operating current value is detected at the normal level, the ion purifier has a function to return to the set value in the product.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this embodiment is not intended to limit the scope of the present invention, but is presented by way of example only.

1 is a schematic diagram illustrating an ion water purifier having a current transformer for controlling an operating current of an electrolytic cell according to a preferred embodiment of the present invention.

First, as shown here, the ion water purifier 100 according to an embodiment of the present invention is provided with a plurality of filters, filter unit 110 for filtering and purifying the time water flowing into the cold and hot water purifier 100, the filter Electrolyzing the purified purified water from the unit 110 to extract the electrolytic cell 120, the electrolytic cell 120 by the electrolytic cell 120 for producing acidic water used for washing and alkaline ionized water used for beverages The drain valve 130 for converting the AC current (AC; alternative current) is converted into direct current (DC) direct current (DC; direct current) to the transformer 140 for applying to the electrolytic cell 120, the secondary side of the transformer 140 A connected current transformer (CT) 170, one line of the secondary output of the transformer 140 is connected to the drain, and a source is connected to the current transformer 170, and this line is connected to the electrolyzer 120. Field effect transistor (FET) connected to the electrode of the; Pulse width modulation (PWM) signals are applied to the gate of the field effect transistor (150) and the gate of the field effect transistor (150) and adjusted to each concentration to be connected to the electrolyzer (120). It consists of a MICOM (160) to control the voltage applied to the transformer (140).

Although not shown, the filter unit 110 is a filter such as a sediment pre-filter, and includes a precipitation filter capable of removing various debris, including rust, soil, and sand dust, and fine impurities of about 1 μm in size. Composite filter, carbon filter using adsorption method of activated carbon, fiber type filtration membrane such as sun carbon filter and UF-membrane filter that can adsorb and remove odor and make water close to nature. The 0.01 ~ 0.04 μm has more than 100 billion pores of 1/10000 size of hair thickness, ultra-precision performance to filter out harmful components and mineral components can be made of living water UF filter and carbon filter as filter unit 110 The last step is to remove unpleasant tastes and odors remaining in the water to maintain the taste of water properly and to remove odors and clean water. After that is made of the carbon filter (post carbon filter).

In addition, the filter unit 110 is a hexagonal molecular ring structure of the human body's cell fluid is most preferred when the force is applied to the tube through which the water passes a strong magnetic force by using a magnetization device made of a special mineral material, the wave occurs It may further include a functional filter, such as a magnetized hexagonal water filter, which can be changed to a pH of 7.2 to 7.4 to increase the penetration of cells in the body and supply water to oxygen and minerals by activating water.

Therefore, when each ion functional water is selected, if the operating condition of the electrolytic cell 120 is satisfied, the ion functional water to be discharged is selected as alkaline water or acidic water, and the electrode change relay of the electrolytic cell 120 is changed to match the water extraction function. A pulse width modulation (PWM) signal is output to the microcomputer 160 to apply a voltage corresponding to the concentration of the ionized water to the electrode of the 120 to turn on / off the FET 150 by a ratio output from the PWM. on / off).

In addition, AC 220V is always connected to the primary side of the transformer 140 of the electrolytic cell 120, and on the secondary side, the AC voltage is converted into direct current through a bridge diode, and then, on the secondary side of the transformer 140. One line of output is connected to the drain of FET 150 and back to current transformer 170 at the source of FET 150. Then, the line and the other line of the secondary output of the transformer 140 are connected to the electrode of the electrolytic cell 120 to apply a voltage to the electrolytic cell 120 according to the on / off of the FET 150.

Thus, when water is supplied to the electrolyzer 120, the actual load of the transformer 140 of the electrolyzer 120 is changed according to the amount and characteristics of the water and is applied to the microcomputer 160 through the current transformer 170 as the current rises. The voltage value rises.

The voltage value applied to the microcomputer 160 is converted into an analog / digital (A / D) value according to a pre-measured current value. When the voltage is higher than or equal to a preset current, the microcomputer 160 generates a PWM signal. By adjusting the value, the transformer 140 of the electrolyzer 120 is automatically converted into a current value that can be tolerated.

When the amount and characteristic of the water are changed again and returned to the normal current value, the microcomputer 160 returns to the initial PWM output.

As described above, the present invention allows the feedback current of the electrolytic cell to be controlled by using a current transformer to prevent damage of the transformer of the electrolytic cell when an overcurrent of the electrolytic cell occurs, and the electrolytic cell is thermally deformed due to the overheating of the electrolytic cell, causing leakage. There is an advantage that can be prevented.
