It is provided with a step (S112) for turning on the vibrator, and a display lamp on step (S113) indicating whether the humidification is in progress at the same time as the step (S112).

Referring to the operation and effects of the present invention configured as described above in detail.

After the operation of the power supply switch for the initial power supply to proceed to step (S100) (S101) of detecting the water level in the water tank, first, the float switch (SW2) in the first water level detection switch 170 installed in the water tank (102) ) Is supplied with water by the water tank 110 to bring the water level fluctuation to cause the movement of the ball 171. Thus, the contact signal of the switch which is determined to be the contact signal of the float switch SW2 according to the movement of the sub-ball 171 is input to the input terminal P3 of the microcomputer 14. That is, when the float switch SW2 is closed, the voltage Vcc divided by the resistor R5 is input to the input terminal P3 of the microcomputer 14 through the resistor R6. At this time, it is input to the input terminal P3 of the microcomputer 14 according to the input signal. At this time, according to the input signal, the microcomputer 14 determines that the water level is changed by the first water detection input unit 12, and proceeds to a step to be described later. Meanwhile, when the switch provided in the key input unit 11, that is, the switch SW1 for instructing various commands, is operated, a low level signal is input to the microcomputer P2 through the resistor R3. When the heater key is operated and input to the microcomputer 14, the process proceeds to step S102, while the heater on key is input while the heater is gradually heated to the step S107 of warming the water supplied to the humidifier 120. If not, the step of turning off the heater (S103) and simultaneously turning off the water supply valve (A) of the water supply valve driver (16), driving off of the vibrator driver (17), and turning on the display lamp (LED) is possible (S104). Proceeding to S105 and S106, the control operation is applied to the output stages P5, P6, P7, and P8 of the microcomputer 14 to invert the inverters I1, I2 and I3. The relays RY1, RY2, and RY3 are continuously de-energized with the generated signal, and the heater HT, the vibration difference TC, and the AC solenoid are interrupted by the interruption of the power supply AC. DE (SV) is turned off.

Of course, the display lamp LED is turned off as a signal inverted through the inverter I4.

If it is determined in step S102 that the heater key is turned on, the process proceeds to step S107 of turning on the heater, and the control operation applies a high level to the output terminal P5 of the microcomputer 14 to the inverter I1. The relay RY1 is turned on with the inverted signal through the heater HIT, which is supplied with the power AC.

By the way, in such a heater-on operation, it is preferable to continuously heat water until the water warms to some extent, and in this invention, it set to predetermined time, ie arbitrary time. Thus, when the water is heated by turning on the heater (S108) for a predetermined time, the bacteria contained in the buffalo are naturally sterilized to be supplied to the ultrasonic humidifier 140.

After the step S108, the microcomputer 14 applies the high level of the water supply valve driving unit 16 provided at the output terminal P6 to drive the AC solenoid SV as an inverted signal through the inverter I2. Open the water supply valve (A) (S109). Here, the water supply valve (A) is open when the AC power magnetizes the AC magnet (6) and sucks the flanger (4). The shield plate (7) opens at the opening / closing portion (2) from the inlet (1a) to the outlet (1b). The water is supplied to the ultrasonic humidifier 140 to be supplied.

Thus, the supply of water through the flow path tube 130 continues to supply to the ultrasonic humidifier 140, when the water reaches the water level to control the contact point of the float switch (SW3) to the contact signal of the float switch (SW3) Due to the input to the input terminal (P4) of the microcomputer 14, the microcomputer 14 recognizes that the ultrasonic humidifier 140 is filled with water (S110).

At the same time, the microcomputer 14 also measures and recognizes the temperature of the water heated by the microcomputer 14 to the input terminal P1 by the temperature sensing element TH of the temperature sensing unit 10 (S111). Thus, when the water supplied to the ultrasonic humidifier 140 is determined to be at a temperature higher than or equal to a predetermined value, the microcomputer 14 applies a high level signal to the output terminal P7 and the oscillator TD as an inverted signal through the inverter I3. Ultrasonic humidification is performed by applying a power source AC to drive the motor (S112). Of course, the humidification display lamp (LED) indicating that the ultrasonic humidification is in progress is turned on (S113).

As described above, the present invention is useful for installing a water supply valve in a supply pipe supplied with water to the ultrasonic humidification tank and installing a sensor to detect the water level in the heater humidification tank and the ultrasonic humidification tank to open and close the water supply valve according to the water level change by the sensor.
