Description

Noise suppression method of night humidifier

The present invention relates to a control method for controlling the driving mode of the humidifier, in particular, night at night to suppress the noise caused by the operation of the fan by stopping the humidification mode using the ultrasonic vibrator at night and the humidification mode through the heater. It relates to a noise suppression method of the humidifier.

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 water absorbs the latent heat and is sprayed into the mist, so that the heater and the ultrasonic vibrator for converting electrical energy into thermal energy are required. In the ultrasonic operation mode using the ultrasonic vibrator, there is a fan that is rotated by a motor as a device for forcibly spraying the generated mist.

Referring to Figure 1 attached to the configuration of the system according to the concept of the humidifier as described above, the user inputs the desired humidity setting, humidification mode, etc. in a predetermined key input form and the temperature of the humidifier Temperature sensing unit 200 for sensing, a humidifier circuit unit 400 for driving a heater or an ultrasonic vibrator that is a humidification device, and a fan motor driver 500 for driving a motor for turning a fan that emits mist generated by the humidifier. And a microprocessor 300 for controlling various operations of the humidifier.

In addition to the system components of the humidifier not shown, the humidity sensor unit for detecting the current humidity, the water level detection unit for detecting the water level of the humidifier, the setting of the user-selected humidification mode or the desired humidity or error status messages, etc. There is a further indication.

In the humidifier configured as described above is provided with a humidification tank to perform its function, this humidification tank should always be provided with a certain amount of water.

In this case, the conventional humidifier operates in a heater operation mode that operates only as a heater, an ultrasonic operation mode that operates as an ultrasonic vibrator, and a merge mode that operates as an ultrasonic vibrator and a heater, as described above. The fan needs to be driven.

Therefore, the noise caused by the rotation of the fan at night acts as a significant obstacle for the user to get a good night's sleep, causing a problem that the user is inconvenient.

An object of the present invention for solving the above problems, by further adding a light detection sensor to switch the operation mode according to the degree of light detection noise suppression method of the night humidifier for suppressing the noise by the operation of the fan at night To provide.

A feature of the present invention for achieving the above object is a method for operating a humidifier having a heater for generating mist and a drive means of an ultrasonic vibrator, a fan for discharging mist generated in the humidification tank to the outside, and a driving unit according to it. A first step of detecting the current peripheral illumination through the light detecting means, and a second step of determining whether the user is asleep by comparing the peripheral illumination detected in the first step with a predetermined threshold illumination, and And a third step of humidifying only the heater by stopping the driving of the fan when it is determined that the user is in the sleep state in the second step.

An additional feature of the present invention for achieving the above object is to stop the driving of the fan and at the same time to stop the operation of the vibrator to humidify only the heater.

As an additional feature of the present invention for achieving the above object, in the second step, the peripheral illuminance detected by the light detecting means is input in the form of a voltage, and the user is in the sleep mode when the reference voltage is smaller than the reference voltage. It is judged that the conversion to.

Hereinafter, a noise suppression method of a night humidifier according to the present invention will be described in detail with reference to the accompanying drawings.

First, the system to which the present invention is applied in terms of system is further provided with a CDS, which is a light detecting element, in addition to the conventional configuration, that is, the configuration mentioned in the description of FIG. Since there is no characteristic configuration other than this, detailed description of the configuration is omitted.

2a and 2b is an exemplary operation sequence for noise suppression of the night humidifier according to the present invention.

After checking the current humidity in step S101, the flow proceeds to step S102. In step S102, it is determined whether the first float switch for checking the minimum water level is in the on state to check the low water level. At this time, if the first float switch is in the on state, it is in a low water state.

If it is determined in step S102 that the first float switch is in the on state, the flow advances to step S103 to turn on the low water LED warning the low water state and to proceed to step S101.

If it is determined in step S102 that the first float switch is in the off state, the flow is not in a low water state and the flow proceeds to step S104. In step S104, it is determined whether the power key is input by the user. If it is determined that the power key is not input, the process proceeds to step S101.

If it is determined in step S104 that the power key is input by the user, the flow advances to step S105 to determine whether the second float switch for checking the highest water level is in an on state in order to determine whether the water level is maintained. At this time, if the first float switch is in the ON state, the water is not full.

If it is determined in step S105 that the second float switch is in the ON state, the flow advances to step S106 to operate a buzzer warning that the water is not full and the flow proceeds to step S103 to turn on the low-altitude LED and then proceeds to step S101.

At this time, the low water LED is used for water shortage warning, not for low water warning.

If it is determined in step S105 that the second float switch is in the OFF state, the flow advances to step S107 to receive the humidity desired by the user. At this time, the user's desired humidity cannot exceed 70% RH.

When the desired humidity is selected by the user in step S107, in step S108, it is determined whether the desired humidity is greater than the current humidity by comparing the current humidity with the desired humidity. The flow advances to S109 to warn that the desired humidity selected by the user is wrong and proceeds to step S101.

If the desired humidity selected by the user in step S108 is higher than the current humidity, the process proceeds to step S110 to start a preparation step for external output of mist generated by first operating a fan.

Subsequently, in step S111, the vibration degree of the ultrasonic vibrator according to the state mode (weak, medium, strong, turbo) according to the strength of the intensity of the user's selected operating state is controlled. In step S112, the heater is driven corresponding to the mode of the operation state selected by the user as in step S111.

When the merge mode operation is performed through the operation up to the step S112, the process proceeds to the step S113 to determine whether the degree of ambient illuminance detected by the provided light detection sensor is greater or smaller than the reference value set as the threshold.

When the detection voltage is greater than the reference voltage when the reference voltage and the detection voltage are compared in the step S113, that is, when the ambient illuminance becomes darker than the threshold illuminance, it is determined that the user intends to go to bed.

In step S114, the vibrator is turned off and the operation of the fan is stopped in step S118. At this time, the driving of the timer (step S115), the predetermined time delay (step S116), and the timer off operation (step S117) during the process from step S114 to step S118 are unnecessary parts of the general humidifier. The reason provided in FIG. 2 is a specific order for applying to the multi-humidifier using the shape-base alloy proposed by the applicant.

Providing a night noise suppression method of the humidifier according to the present invention operating as described above, it is possible to solve the problem that the user can not take a good night's sleep by the noise generated when the user rotates the fan.
