Current control method of heater ultrasonic humidifier

The present invention relates to a humidifier.

In particular, the present invention by performing a mode control step to reduce the damage (damage) of the vibrator to reduce the initial load on the vibrator (in-rush current) to precisely control the operation of the humidifier to stably humidify The present invention relates to a current control method of a heater ultrasonic humidifier to perform a function.

As is well-known, homes and offices operate air-conditioning facilities (e.g., air conditioners, fans, boilers, stoves, etc.) to keep the temperature fluctuating according to the season. By stimulating the situation is causing various diseases, including respiratory diseases.

In particular, household appliances (eg, television sets, refrigerators, air conditioners, video cassette recorders, sound equipment, etc.) used in homes and offices are diversified, and as the number thereof increases, the heat generated during the operation of the indoor air is reduced. As the temperature is increased, the humidity value of the indoor space is further lowered.

When the indoor space is dried in this way, the health of people (healthy people) is not only harmed, but also a fatal adverse effect on a weak person such as a child, an elderly person or a patient.

Accordingly, various measures are taken to keep the humidity value constant. Especially in the homes and hospitals where children and the elderly live, the humidity level is kept constant so that the indoor space can be made more comfortable. There are various means, one of which is the humidifier.

The humidifier is a device that can control the humidity of a certain space, which is installed in a confined space such as a home or office, converts water into an atomized state of water vapor or fine particles, and discharges it into the indoor space to change the humidity value of the indoor space. It is to perform the function of adjusting.

Conventional humidifier for adjusting the humidity of any space, as shown in Figure 1 to 2, the key is formed for setting the overall operating environment of the humidifier, such as setting the desired humidity value of the space to be humidified The input unit 12, the humidity sensor 14 installed to be exposed to the outside of the humidifier to detect the humidity value of the indoor space, and installed in the heating tank 120 or the humidifying tank 130 in the water tank 110 The heater drive unit 20 and the vibrator drive unit 22 are controlled to maintain a desired humidity value by operating the float switch 18 operating on / off and the heater 140 and the vibrator 150 by the level of the incoming water. And a heater driver 20 and an oscillator driver 22 for selecting an operation mode of the heater 140 and the vibrator 150 under the control of the microprocessor 10. Of the microprocessor 10 The fan motor driver 24 controls the operation of the fan motor 160 to discharge the atomization (water vapor) generated by the heater 140 and the vibrator 150 to the outside of the humidifier through the discharge port 170. Consists of

However, since the conventional humidifier has a master clock having a certain period (for example, a master clock having 60 cycles per minute) is applied to the microprocessor that controls the overall operation, the microprocessor has a temperature sensor or humidity. Since the operation of recognizing the input value of the sensor or controlling the operation of the vibrator, fan motor and heater is controlled by a master clock having 60 cycles per minute, there is a limit to precisely controlling the operation of the humidifier.

That is, since various data input to the microprocessor are input to the master clock having 60 cycles per minute, the microprocessor encounters new data each time of the master clock, and does not encounter new data between the master clocks. The drawback is that it does not provide a more detailed picture of the humidification of the humidifier or the environment.

The present invention has been made to solve the above-mentioned drawbacks, and its purpose is to reduce the damage of the vibrator by performing mode control step by step to reduce the load on the vibrator at the initial stage, i.e. the operation of the humidifier by reducing the in-rush current. The present invention provides a method of controlling a current of an ultrasonic humidifier in a heater to precisely control the temperature and stably perform a humidification function.

To achieve the above object, the present invention provides a float switch on check step of checking an on state of a float switch, a low water display step of displaying a low water level in a humidification tank when the float switch is switched to an on state, and the float switch is in an off state. If desired, the desired humidity setting step of setting the desired humidity, a humidity value comparison step of comparing the set desired humidity value and the current humidity value, an error message output step of outputting an error message if the current humidity value is large, and the current humidity If the value is small, the ON step of turning on the motor and the heater, the mode checking step of checking whether the mode is in the weak mode at the same time as the heater is turned on, and if the humidification mode is the weak mode, the humidification mode is performed in the weak mode. Mode check step to check whether it is in the weighting mode. If the humidification mode is the medium mode, run the humidification mode in the weak mode for 2 seconds and then change the humidification mode to the medium mode. Mode execution step of executing the humidification mode, and if the humidification mode is the strong mode, the humidification mode is executed in the weak mode and the medium mode for 2 seconds, and the humidification mode is executed in the strong mode, and if the humidification mode is the turbo mode, the humidification mode is weak. , Turbo mode execution step of running for 2 seconds in the medium mode, and then in turbo mode.

The configuration of the present invention is the same as the configuration of the humidifier of Figure 1 key input unit 12, humidity sensor 14, float switch 18, heater driver 20, vibrator driver 22, fan motor driver 24 And the like, but the algorithm of the microprocessor is reinforced so as to achieve the above object, and the other components are designed to operate under the control of the microprocessor.

A mode checking step (S10) of checking whether the mode is weak, a mode checking step (S12) of performing a humidification mode in the weak mode if the humidification mode is a weak mode, and checking whether the humidification mode is the medium mode, and When humidification mode is medium mode A mode execution step (S40) for executing the humidification mode in the medium mode after executing the card in the weak mode for about 2 seconds, and a strong mode checking step (S15) for checking whether the humidification mode is the strong mode again, if not the medium mode; In the strong mode, the humidification mode is executed in the low and medium modes for 2 seconds, and then the mode execution step (S50) for executing the humidification mode in the strong mode, and the turbo mode checking step of checking whether the humidification mode is the turbo mode (S19). And turbo mode execution step (S60) of returning to the mode check step if it is not the turbo mode, and executing the humidification mode in the low, medium, and strong modes for 2 seconds, and then executing the turbo mode in the turbo mode.

Figure 3-a is an overhead caused by the in-rush current in the turbo mode, b is an oversheet in the weak mode, to perform the humidification according to the mode, whatever mode is performed initially at the start of the humidification. Therefore, the vibrator is exerting pressure. Therefore, the present invention can perform the humidification function of the stable humidifier in the feed-in (feed-in) method as shown in Fig. 3c contrary to the above method.

This will be described based on the flowchart of FIG. 4.

First, while detecting the current humidity value by the humidity sensor (S), the microprocessor determines whether the power is switched on by the power switch operation of the key input unit (S1).

If it is determined that the power supply is on, it is again checked whether the float switch is on (S2). If the float switch is on, the low water level in the humidification tank is displayed by the LED (S4).

That is, when it is determined that the humidification tank is in the low water state, the low water buzzer S3 and the low water LED S4 are turned on so as to indicate that the humidification tank is in the low water state. Subsequently, after the fan motor is operated for a predetermined time, the fan motor is switched to the off state, and the heater and the vibrator switch to the off state immediately when the humidification tank is in a low water state.

However, when the humidifier is filled with water, the desired humidity value by the external key input is set (S5) and the current humidity value detected by the humidity sensor is compared (S14).

As a result of comparison, if the current humidity value is less than the desired humidity value, it is determined that the humidifier operation is impossible to reach the set desired humidity value and outputs a message for notifying (S7), and then operates the fan motor for a predetermined time and then turns it off. The heater and the vibrator switch to the off state immediately when the humidification tank is in the low water state.

Therefore, if the current humidity value is greater than the desired humidity value, while supplying the operating power to the fan motor (S8) and heater (S9), if the humidification mode of the humidifier is weak mode (S10), run the vibrator in weak mode (S11) and the humidification mode is If it is not the weak mode, it is checked whether the set humidification mode is the medium mode (S12). If the medium mode is executed, the humidification function is executed in the weak mode for about 2 seconds (S13), and then the humidification function is executed in the medium mode (S14).

Meanwhile, if the humidification mode is the strong mode, the humidification function is executed in the weak mode and the medium mode for about 2 seconds (S16) and (S17), and then the humidification function is executed in the strong mode (S18). Therefore, when the humidification mode is the turbo mode (S19), the humidification function is executed in the night, medium and strong modes (S20), (S21) and (S22), and the humidification function is executed in the turbo mode (S23).

By controlling the operation of the vibrator and the heater in this way it is possible to more precisely control the operation of the humidifier.

As described above, the present invention has the effect of maintaining the humidification function of the humidifier more precisely by initially reducing the load on the vibrator and precisely controlling the operation of the humidifier.
