Description

How to decontaminate the humidifier.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier, and in particular, decontamination of a humidifier to remove a vibrator generated by water staying in a humidification tank for a long time and foreign substances in the humidification tank and bacteria derived by the foreign substances by heating the heater for a predetermined time. It is about a method.

In general, the humidifier has a humidifier as an essential device to increase the humidity in the room by evaporating the water to the humidifier, and known humidifiers for evaporating water include heaters and ultrasonic vibrators.

As is well known, the heater converts electrical energy into thermal energy to supply heat to the water of the humidifier to generate mist, and in the case of an ultrasonic vibrator, to generate mist by converting the supplied electrical energy into a form of ultrasonic vibration energy. do.

Referring to FIG. 1 attached to the schematic configuration of the humidifier operating as described above, a key input unit 100 for inputting a desired humidity setting or a humidification mode in a predetermined key input format, and humidity sensing for detecting a current humidity The user's request input from the key input unit 100 based on the input unit 200, the water level detection unit 300 for detecting the level of the humidification tank, and the data output from the detection unit (200, 300) A microprocessor 700 for controlling various operations of the humidifier by a signal, a humidifying circuit unit 500 for driving a heater and an ultrasonic vibrator, each of which is a humidifier, and a microprocessor 700 of the microprocessor 700. A display unit 600 for displaying an option for a humidification mode input by the user through the key input unit 100, a desired humidity setting error, an operation state of the system, etc. And a fan motor drive unit 400 for driving a motor that turns a fan that emits mist (humidity) produced by the humidifier.

The humidification mode according to the mist amount of the mist in the humidifier is often a strong, medium, weak mode, in the case of the ultrasonic humidifier by changing the current supplied to the ultrasonic vibrator (for example, in the strong mode 750 milliamps (mA), 650 mA for medium mode and 550 mA for weak mode). Therefore, the user selects the humidification mode according to the spray amount of the mist according to the preference.

When water is stagnated for a long time in the humidifier in the humidifier, foreign matters in the moss are caught in the humidifier and the vibrator. In this case, even if the vibrator receives the same current, the vibrator corresponds to the humidification corresponding to the supplied current. You do not have the quantity. As such, when the efficiency of the vibrator decreases, the reliability of the operation of the humidifier of the user is lowered. The occurrence of the above problem occurs because the user does not clean the vibrator, which causes unnecessary AS requests.

And, as described above, if the foreign substance is stuck in the vibrator, the foreign substance acts as a nutrient of the bacteria, and when the humidifier is used later, the bacteria are discharged to the space to be humidified through the discharge hole together with the mist and the health of the user. There was a problem that hurts.

An object of the present invention for removing the above problems is to remove the vibrator and foreign matter in the humidification tank and bacteria derived by the foreign matter caused by the water stays in the humidification tank for a long time by heating the heater for a predetermined time. The present invention provides a method for decontaminating a humidifier.

To provide a way.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a schematic configuration diagram of a humidifier implementing the sterilization method of the humidifier according to the present invention.

The humidifier includes a key input unit 100 for inputting a desired humidity setting or a humidification mode in a predetermined key input format, a humidity detector 200 for detecting a current humidity, and a water level detector 300 for detecting a water level of the humidifier. And a microprocessor 700 that receives data output from the detectors 200 and 300 and controls various operations of the humidifier according to a user's request signal input from the key input unit 100 based on the received data. The humidification circuit unit 500 for driving the heater 520 and the ultrasonic vibrator 540 which are the microprocessor 700, respectively, and the driving time of the heater 520 are controlled by the microprocessor 700. An optional or desired humidity setting error for the humidification mode input by the user through the key input unit 100 under the control of the timer 800 for counting and the microprocessor 700 and the operation of the system It consists of a display such as a state in which the display 600, and a fan to flush the mist (moisture) generated by the humidifier (fan) and the fan motor driver 400 for driving the motor to turn the fan.

3 is a flowchart illustrating a sterilization method of the humidifier according to the present invention.

The microprocessor senses the state of the low water switch (S111), and when the low water switch is ON, operates a display unit to warn the low water state (S112), and operates a timer to count the low water state maintaining time (S113). do.

The microprocessor determines in step S114 whether the time counted by the timer in the counting step S113 has elapsed a predetermined time (the low water state holding time T1 which starts contamination of the humidifier and the vibrator).

If the time counted by the timer in the determination step (S114) is less than the predetermined time T1, the process returns to the low water switch determination step (S111), and the time counted in the counting step (S113) If it is greater than the predetermined time T1, the controller 100 operates in the pollution warning mode (S115).

The microprocessor performing the pollution warning mode (S115) returns the operation of the humidifier to the low water switch determination step (S111) to determine whether the low water switch is on, that is, the power of the humidifier is on if it is not in the low water state ( S116) and if the power of the humidifier is not on, the process switches to the timer counting step S113.

When the power is turned on in the power state determination step S116, the microprocessor determines whether there is a pollution indication signal (S117), and when there is no pollution indication signal in the determination step S117, the humidifier operates in a normal humidification mode (S200). Let's do it.

If there is a pollution indication signal in the contamination display determination step (S117), the microprocessor turns off the vibrator and operates the heater and the timer (S118 to S120).

The timer counts the operating time of the heater in a state in which the pollution indication signal is generated, and the microprocessor counts the counted time and a predetermined time (a foreign matter generated in the humidifier and the vibrator based on the time counted by the timer). And heater operation time T2) to allow bacteria to be removed (S121).

If the time counted in the comparison step (S121) is less than the predetermined predetermined time (T2), the microprocessor returns the operation step of the humidifier to the low water switch determination step (S111) to continue until water remains in the humidifier tank The heater is operated, and if the counted time is greater than the predetermined time T2, the timer and the heater are stopped (S122 to S123), and the operation of the humidifier is returned to the humidification mode operation step (S200).

Therefore, according to the present invention, the foreign matter generated in the humidification tank and the vibrator and the bacteria derived by the foreign matter are removed by heating the water of the humidification tank.

The present invention operated as described above is because the foreign material generated in the humidifier and the vibrator, and the bacteria derived by the foreign material is removed by heating the water of the humidifier tank for a predetermined time, the vibrator by the foreign matter There is an effect that the deterioration of the characteristics of the product does not occur, so that the failure of the mist part condition does not occur, thereby increasing the reliability of the user's product. In addition, since the generation of bacteria due to the contamination of the humidifier is suppressed and the bacteria generated in the humidifier due to the contamination of the humidifier are removed by the heating of the heater, the disease caused by the conventional bacteria does not occur and thus the user can use the humidifier. Satisfaction is improved.
