The present invention relates to a method of controlling the air volume of a humidified air purifier, and more particularly, to control the air flow rate of the humidifying air purifier when the air volume control of the humidified air purifier to allow the user to feel the fan noise less It is about a method.

Recently, among the household appliances that are being released, such as air purifiers or dehumidifiers are being released separately according to each use purpose, and has gained favor from consumers due to the improvement of living standards.

In general, air purifiers continue to develop technologies such as basic filter method and anion function, and even dehumidifiers have simple functions such as refrigerant circulation method and thermoelectric method, and technology of control function is improved according to time and pollution degree. Products with various functions are spreading.

Recently, in order to meet various demands of consumers, a humidifying air purifier product having both a humidifying function and an air cleaning function in one product has been introduced.

The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

The humidifier air purifier is rapidly reaching the target rotational speed of the fan corresponding to the strong wind when changing from the low wind with little noise. Accordingly, there is a problem that users relatively feel the noise of the fan largely due to the change in the amount of wind from the strong wind to the strong wind.

Accordingly, an object of the present invention is to provide a method for controlling the air volume of a humidified air cleaner to allow a user to feel the noise of the fan by gradually increasing the rotation speed of the fan when the air volume is rapidly changed.

Air flow rate control method of the humidified air purifier according to the present invention, the step of detecting the air pollution; Determining a target rotational speed of the fan motor according to the air pollution degree; And controlling the air volume to reach the target rotational speed by repeatedly increasing the rotational speed of the fan motor by a predetermined speed according to the comparison result between the target rotational speed and the current rotational speed.

In the present invention, the controlling of the air volume may include determining whether a difference between the target rotational speed and the current rotational speed exceeds a reference value; Increasing the rotational speed of the fan motor by the set speed when the reference value is exceeded; And determining whether the current rotational speed has reached the target rotational speed.

In the present invention, the reference value is characterized in that the threshold for generating noise in accordance with the change in the rotational speed of the fan motor.

In the present invention, the step of increasing by the set speed is characterized in that it is repeatedly increased at regular time intervals.

As described above, the present invention allows the user to feel the noise of the fan less by gradually increasing the rotational speed of the fan motor by the set speed when adjusting the air volume of the humidified air cleaner.

1 is a view for explaining the configuration of the air volume control device of the humidified air purifier according to an embodiment of the present invention.
2 is a view for explaining the air volume control method of the humidified air purifier according to an embodiment of the present invention.

Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for illustrating the present invention, and the scope of rights of the present invention is not limited by these embodiments.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a view for explaining the configuration of the air volume control device of the humidified air purifier according to an embodiment of the present invention.

As shown in FIG. 1, the apparatus for controlling air volume of a humidified air purifier according to an exemplary embodiment of the present invention includes an air pollution detector 1, a controller 2, a memory 3, and a fan motor 4. do.

The air pollution level detecting unit 1 measures the indoor air pollution level and provides the control unit 2.

The control unit 2 determines the rotational speed of the fan motor 4 according to the indoor air pollution degree from the air pollution degree detecting unit 1.

The memory unit 3 stores the target rotational speed of the fan motor 4 according to the indoor air pollution degree. Of course, the memory unit 3 stores data for controlling the humidification and air cleaning of the humidified air cleaner.

The controller 2 determines the target rotational speed of the fan motor 4 according to the air pollution degree, and prevents noise due to the change of the rotational speed of the fan motor 4 according to the comparison result between the target rotational speed and the current rotational speed. The amount of air is controlled to repeatedly reach the target rotational speed by repeatedly increasing the rotational speed of the fan motor 4.

The fan motor 4 rotates the fan under the control of the controller 2 and provides a feedback signal according to the rotation to the controller 2.

The control unit 2 calculates the current rotational speed of the fan motor 4 with the feedback signal provided from the fan motor 4.

2 is a view for explaining the air volume control method of the humidified air purifier according to an embodiment of the present invention.

Referring to FIG. 2, first, the control unit 2 receives an indoor air pollution degree measured from the air pollution degree detecting unit 1 (S1).

Subsequently, the target rotational speed of the fan motor 4 according to the indoor air pollution degree stored in the memory unit 3 is read to determine the target rotational speed of the fan motor 4 according to the indoor air pollution degree (S2).

Next, the difference between the determined target rotational speed and the current rotational speed is compared with the reference value (S3).

Here, the reference value is a threshold value at which noise occurs in accordance with the change in the rotational speed of the fan motor 4.

That is, it is determined whether the difference between the target rotational speed and the current rotational speed exceeds a threshold that can generate noise.

At this time, if the difference between the target rotational speed and the current rotational speed exceeds the reference value, the rotational speed of the fan motor 4 is increased by the set speed (S4).

Then, it is determined whether the current rotation speed has reached the target rotation speed (S5).

Subsequently, if the current rotation speed does not reach the target rotation speed, it is determined whether a predetermined time has elapsed (S6).

When a predetermined time elapses, the process returns to the process of increasing the rotational speed of the fan motor 4 by the set speed (S4).

In other words, if the threshold value that can generate noise is exceeded according to the comparison result between the target rotational speed and the present rotational speed, the rotational speed of the fan motor 4 is repeatedly increased by a set speed at regular intervals to reach the target rotational speed. Control the air volume

On the other hand, if the difference between the target rotational speed and the current rotational speed is less than the reference value, it is determined that the noise does not occur even if the change in the rotational speed of the fan motor 4 accelerates the current rotational speed to the target rotational speed as conventionally (S7).

As described above, the present invention allows the user to feel the noise of the fan less by gradually increasing the rotational speed of the fan motor by the set speed when adjusting the air volume of the humidified air cleaner.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is understandable. Accordingly, the true scope of the present invention should be determined by the following claims.
