5 to 7 are detailed circuit diagrams showing each circuit block of the air cleaner of FIG. 4, FIG. 5 shows a main circuit, FIG. 6 shows a circuit of an ozone generating unit, and FIG. 7 shows a circuit of a display unit. It is shown.

As shown in FIG. 5, the command selector 55 is composed of a plurality of switches. The switches are installed at the front of the main body 10 and are turned on by a user's operation to output a power supply signal. 55-1), a sterilization switch 55-2 installed on the front of the main body to turn on / off the operation of the ozone generator 40, and periodic operation of the ozone generator 40 installed on the front of the main body. And an ozone time switch 55-3 for selecting time, and volume up / down switches 55-4 and 55-5 for selecting the amount of ozone generated by the ozone generator 40 and its intensity.

According to the selection of each input switch of the command selector 55, the controller 100 controls an operation corresponding thereto. First, when the power switch 55-1 is turned on, the controller 100 supplies the power supply unit 50. The control signal is output to the negative ion generator 20, the ozone generator 40, and the fan 80 to supply power.

That is, the negative ion generator 20 generates an AC signal when the operating voltage is applied to a transistor that alternately operates the negative ion control unit 60 according to the control signal of the controller 100 when the power switch 55-1 is turned on. The negative ion generator 65 is supplied to the negative ion generator 65, and is generated between the negative electrode needle 32 and the negative electrode plate 36 by generating a high DC voltage of about 2 kV from the negative ion generator 65 including a capacitor and a diode. Accordingly, the air insulation formed between the anion needle 32 and the anion plate 36 is broken, so that electricity flows into the air. That is, the strong negative electrons are discharged into the air from the negative ion needle 32 by being supplied from the removable anion generator 20 to the ion needle frame 31 in which the plurality of negative ion needles 32 are formed. Is adsorbed on the positively charged anion plate 36.

However, when the electrostatic precipitator plate 35 or the ion needle frame 31 of the anion generator 20 is separated from the anion mounting unit 11, a safety switch (not shown) mounted at a predetermined position of the anion mounting unit 11 is provided. Open and no power is supplied to the negative ion generator 20.

When the sterilization switch 55-2 of the command selector 55 is turned on or off, the controller 100 turns on or off the driving transistor of the ozone driver 85 to supply the ozone generator 90. When the sterilization switch 55-2 is turned off, the transistor of the ozone driver 85 is turned off to cut off the power supplied to the ozone generator 90 to stop the operation of the ozone generator 40. do.

In addition, when the volume up / down switches 55-4 and 55-5 are selected, the controller 100 simultaneously controls the fan driver 75 and the ozone driver 85, and the fan driver 75 and the ozone generator ( 90) Adjust the wind speed and ozone generation by controlling the amount of current supplied up or down. For example, according to the volume of the volume up / down switches 55-4 and 55-5, the speed of the fan 80 is divided into four stages (slow speed, low speed, medium speed, high speed, etc.), and the ozone generation amount is also four stages ( 5 pyeong, 10 pyeong, 20 pyeong, 30 pyeong).

In addition, the fan driver 75 varies the current supplied to the fan 80 under the control of the controller 100 according to the selection of the volume up / down switches 55-4 and 55-5 to generate the amount of ozone generated. The controller 100 supplies power to the ozone generator 40 according to the selection of the sterilization switch 55-2 and operates the memory 100 according to the selection of the ozone time switch 55-3. On / off of the ozone generator 40 is controlled based on the periodic operation and stop time stored in the). That is, when the ozone time switch 55-3 is selected, the ozone driving unit 85 is controlled to turn the ozone generator 40 on or off at regular time intervals, for example, by repeating the 2-minute off function for 3 minutes of operation. Will be performed.

In addition, when each switch of the command selector 55 is selected, the controller 100 outputs a display control signal corresponding to the light emitting diodes LED1 to LED12 of the display unit 95 as shown in FIG. 7. For example, when the power is turned on, the power indicator LED12 is turned on, or when the sterilization switch 55-2 is turned on, the ozone indicators LED1 and LED11 are turned on or the ozone time switch 55-3 is turned on. If you turn on the timer operation light (LED0) or push the volume up / down switch (55-4, 55-5) once, that is, two light emitting diodes (LED5-LED7, LED4- every step) Displaying such as LED8, LED3-LED9, LED2-LED10) is sequentially turned on.

Therefore, the ozone generator 40 receives power by corona discharge according to the output signal of the controller 100, generates ozone, and reacts with harmful organic substances to generate oxygen.

That is, when the power switch 55-1 and the sterilization switch 55-2 are turned on in FIG. 5, the ozone generator 40 passes through the ozone driver 85 and the ozone generator 90 according to the control signal of the controller 100. Electricity flows to the inner electrode 43 and the outer electrode 45 of the C, and accordingly, a high-pressure electricity flows between the neon lamp 41 and the outer electrode plate 45 to generate a quiet discharge. Ozone is generated.

In addition, when the ozone time switch 55-3 is operated, the ozone driver 85 is controlled by a program stored in the internal memory 105 of the controller 100. For example, the ozone generator 40 is operated for 3 minutes. By repeatedly performing the operation for 2 minutes after the operation, it was possible to supply the appropriate ozone to the room.

In addition, when operating the volume up / down switches 55-4 and 55-5, the controller 100 controls the fan driver 75, the ozone driver 85, and the ozone generator 90 to control the fan 80. By adjusting the speed of the ion and the amount of ions emitted and its intensity, the volume up / down switches (55-4, 55-5) is the user's ability and performance of the air cleaner to suit the indoor environment according to the equilibrium of the house Make it adjustable.

The selection and operation of each function is displayed on the display means 67 such as a light emitting diode according to the display control signal of the controller 100, so that the user can visually check the operation state of the air cleaner.
