Description

How to notify when the vibrator is cleaned using the full water detection switch

The present invention relates to an ultrasonic humidifier, and in particular, to detect the operation relationship between the humidification tank and the water supply tank using a full water detection switch, to estimate the current humidification amount accordingly, and to judge that the range of the reference value set based on the estimated humidification amount is exceeded. The present invention relates to a method of notifying the cleaning time of a vibrator using a full water detection switch for alerting the case by defining the cleaning time of the vibrator.

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 according to a signal, a humidification 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 driving unit 400 for driving a motor that turns a fan that emits mist (humidity) generated by the humidifier.

In the conventional humidifier configured as described above, the humidification mode according to the spray amount of mist 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 Change the spray volume in milliamps (mA), 650 mA in medium mode, 550 mA in weak mode. Therefore, the user selects the humidification mode according to the spray amount of the mist according to the preference.

However, even if the vibrator is supplied with the same current, when the foreign material is caught in the vibrator or the vibrator is damaged, the vibrator may not have a humidification amount corresponding to the supplied current.

As such, when the efficiency of the vibrator is lowered, the user is less reliable in the operation of the humidifier. The occurrence of such a problem occurs because the user does not clean the vibrator, which causes unnecessary AS requests. Therefore, there is a need for the development of a technology that can warn the user of the cleaning time of the vibrator.

An object of the present invention for solving the above problems is to detect the operation relationship between the humidification tank and the water supply tank using a full water detection switch, estimate the current humidification amount accordingly, and then buck the range of the reference value set based on the estimated humidification amount. If it is determined that the flying time to determine the cleaning time of the vibrator to provide a vibrator cleaning time notification method using a full water detection switch to warn.

A characteristic of the present invention for achieving the above object is provided with a water level detecting unit 300 for detecting whether the water in the humidification tank is full, and the inside of the humidification tank having a certain height and the bottom of the humidification tank If a water tank is provided at a position, and the water present in the humidification tank is at the full water level, the water present in the water supply tank is not supplied to the inside of the humidification tank, and if the water is insufficient in the full water level, the water present in the water tank is present. Is a humidifier configured to be supplied to the interior of the humidifier:

A first process of detecting and storing information according to the time period of alternating the full water state and the water supply state in the humidification tank due to the humidification operation during the operation of a normal oscillator; A second process of detecting a water supply alternating time through the water level detecting unit 300, a third process of comparing the bay / water supply alternating time detected in the second process with information stored through the first process, and the first process And a fourth step of alerting the contaminated state of the vibrator when none of the stored water / supply alternating times is the same among the information stored through the first step.

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

First, referring to Figure 2 attached to the configuration and operation of the humidifier tank and the water supply tank in the structure of the humidifier, the inside of the humidification tank is provided with a water supply tank at a position having a certain height, the water supply The water supply port of the water supply tank for supplying water from the tank to the humidification tank is formed downward (see attached FIG. 2A).

Therefore, if the water present in the humidification tank is at the full water level, the water present in the water supply tank is not supplied to the inside of the humidification tank, but if the water is insufficient to some extent in the full water level state, the water present in the water supply tank is inside the humidification tank. Supplied.

In this case, the reason why the water in the humidification tank is reduced at the full water level is due to the generation of mist for humidification. As shown, it is almost triangular in shape with respect to the full water level.

The present invention focuses on the change in the water level of the humidification tank according to the operation relationship between the humidification tank and the water supply tank as described above, and FIG. 3 is an operation flowchart for explaining a vibrator cleaning timing notification process using the full water detection switch.

In step S101, the microprocessor 700 determines whether there is input of power, and proceeds to step S102 only when there is power supply. In step S102, it is determined through the water level detecting unit 300 provided in the humidification tank whether or not it is in full water.

At this time, if it is determined in step S102 that the water is not in full water, the flow advances to step S103 to determine whether the water is in the low water level through the water level detecting unit 300. If it is determined in step S103 that the water is low, the flow proceeds to step S200 to display the low water state and proceeds to the low water warning mode for performing a function such as stopping the operation of the system.

On the other hand, if it is determined in the step S102 that the water level is full or not in the step S103, the flow advances to step S104 to determine whether an operation key (including a humidification mode setting) by the user is input. When it is determined in step S104 that there is an input of an operation key, the heater is driven (step S105) according to the set humidification amount, and the vibrator and the fan are driven (step S106, step S107).

Thereafter, in step S108, the timer is operated to count the driving time. In step S109, it is determined whether the water is in full water through the water level detection unit 300 provided in the humidification tank. At this time, while the full water detection signal is generated, the flow proceeds to step S105 to continuously perform the above-described humidification operation. If the full water detection signal is not generated, the flow proceeds to step S110 and the counter timer value in step S108 exceeds the set threshold value. Determine if you do. At this time, the threshold value corresponds to 1/2 of the period of the triangular wave shown in FIG. 2B.

In step S110, when it is determined that the counter timer value does not exceed the set threshold value, the flow proceeds to step S105. When it is determined that the counter timer value exceeds the set threshold value, the flow proceeds to step S111. In step S111, after confirming the current humidification mode, the process proceeds to step S112. In step S112, the time corresponding to the humidification mode in the data table as shown in Table 1 below based on the current humidification mode confirmed in the step S111. It is determined whether and the value counted in step S108 are the same.

Table 1

Humidification mode River mode Mode About mode Critical time 10 sec 5 sec 3 sec

That is, if the current mode is the strong mode, the counted value from the water supply tank to the point where the water is supplied by the water is changed to the mist and discharged to the outside, and the counted value is normal if the current mode is 10 seconds. I think this is stuck.

Therefore, in step S112, if it is determined that the time corresponding to the humidification mode and the value counted in step S108 are the same in the data table shown in Table 1 on the basis of the current humidification mode identified in step S111, the step S105. If it is determined that the difference is not the same, the flow proceeds to step S300 and the foreign material is stuck in the vibrator, so the vibrator cleaning time warning mode should be cleaned. Thereafter, in step S113, it is determined whether the water is in the low water level through the water level detecting unit 300. If it is determined in step S113 that the water is low, the flow proceeds to step S400 to perform an error warning mode that warns the user that an error has occurred.

On the other hand, if it is determined in step S113 that the terminal is not in the low water state, the flow proceeds to step S114 to determine whether the end key is input by the user. If the end key is not input, the process proceeds to the step S105. The humidification operation is terminated.

Providing a method for notifying the vibrator cleaning time using the full water detection switch operating as described above, if the efficiency of the vibrator is degraded due to contamination, the user is less reliable in the operation of the humidifier. It is caused by not cleaning, which solves the problem of generating unnecessary AS request.
