2A and 2B are flowcharts illustrating an operation of the humidifier according to FIG. 1.

When the operating voltage is input to the humidifier through the voltage input unit provided in the humidifier (S111), the microcomputer determines whether the water in the humidifier is in a dry state based on the signal output from the water level detector (S112).

If it is determined in the determination step (S112) that the microcomputer state is a microcomputer operation unit (S113), thereby causing the user to make a low water (S114), and if it is determined in the determination step (S112) the microcomputer state Determines whether there is a key input from the key input unit (S115).

When it is determined in step S115 that there is a key input from the key input unit, an operation control signal according to the signal applied from the key input unit is applied to the heater, the vibrator and the fan driving unit to operate the heater (S116), and the vibrator is operated ( In step S117, the fan driving unit is operated (S118), and if it is determined that there is no key input in the determination step (S115), the operation stop step (S124) is executed.

In addition, the microcomputer operates the infrared sensor (S119) to determine whether an obstacle exists in the spray direction of the nozzle and the mist in front of the nozzle (S120). If there is no obstacle, the microcomputer determines whether the spray amount operation mode input is input from the key input unit (S121). .

If there is no spray amount operation mode input in the determination step (S121), the humidification process returns to the heater operation step (S116), and if there is a spray amount operation mode input, the operation mode of the humidifier is switched (S122) according to the input spray amount operation mode.

When it is determined in step S120 that an obstacle exists, the microcomputer stops the vibrator operation (S125) and operates the timer (S126). The time elapsed from the time when the obstacle is detected by the timer is detected, and during execution of the time detection operation by the timer, the microcomputer detects a signal input from the infrared sensor and determines whether an obstacle is present (S127). .

If there is no obstacle in the determination step S127, the vibrator is operated (S128) to return the humidification process to the predetermined step S120, and if the obstacle is present in the determination step S127, the microcomputer detects by the timer. The time T is compared with the preset predetermined time t1 (S129), and if the detected time is less than the preset predetermined time, the operation of the humidifier is returned to the timer operation step S126, and the detected time is If greater than or equal to the predetermined time, the microcomputer stops the operation of the heater (S130).

The microcomputer that stopped the operation of the heater (S130) determines whether an obstacle exists (S131), and if the obstacle does not exist, operates the heater (S132) to return the operation process of the humidifier to the vibrator operation step (S128), and the obstacle If present, the detected time T is compared with the predetermined time t2 (S133).

If it is determined that the time detected in the comparison step (S133) is greater than the predetermined predetermined time, the microcomputer stops the timer (S134), and performs the operation stop step (S124). If the time detected in the comparison step S133 is not greater than a predetermined time, the operation step returns to the heater operation stop step S126.

Therefore, according to the present invention, if there is an obstacle in the front of the nozzle during the operation of the humidifier, the microcomputer operates the timer from the moment when the infrared sensor detects the presence of the obstacle and continuously detects the obstacle until a predetermined time. The operation of the humidifier is stopped by stopping the operation of the vibrator and the heater, and if the obstacle disappears before the predetermined time elapses, the humidifier operation is continuously performed by operating the vibrator and the heater step by step as time passes.
