If the difference between the duty ratio of the pulse signal in the normal clean mode and the humidification of the pulse signal in the clean mode is less than the difference between the preset ratio, if the two conditions are satisfied, the humidification air purifier Computing unit for determining that the filter is not mounted; provides a determination system without a humidification filter of a natural humidifying air cleaner comprising a.
In one embodiment of the present invention, when the difference between the duty ratio of the pulse signal in the normal clean mode and the duty ratio of the pulse signal in the humidification clean mode is less than the difference between the preset ratio, the operation unit is not equipped with a humidification filter The present invention provides a determination system without a humidification filter of a natural humidifying air purifier, wherein a message or an alarm signal is displayed on a display unit.
In another embodiment of the present invention, the predetermined speed difference provides a determination system without a humidification filter of a natural humidifying air cleaner, characterized in that within 20rpm.
Another aspect of the invention, the first step of determining whether the natural humidifying air purifier is set to the humidifying clean mode; A second step of measuring a speed of a motor for driving a fan of the natural humidifying air purifier when it is determined that the natural humidifying air purifier is set to a humidifying clean mode; Receiving a speed signal of the motor to determine whether a difference between a rotation speed of the motor and a predetermined reference speed is smaller than a difference between a preset speed; A fourth step of detecting a pulse signal generated by a motor of the natural humidifying air cleaner; A fifth step of receiving a pulse signal of the motor and determining whether a difference between a duty ratio of a pulse signal in a general clean mode and a duty ratio of a pulse signal in a humidified clean mode is smaller than a difference between a preset ratio; And a sixth step of determining that the natural humidifying air purifier is not equipped with a humidification filter when all of the determination conditions of the third and fifth steps are satisfied. The humidification filter of the natural humidifying air purifier is not installed. Provide a method of judgment.
In one embodiment of the present invention, if both determination conditions are satisfied, the humidification filter of the natural humidifying air purifier, characterized in that it further comprises a seventh step of displaying a message or an alarm signal that the humidification filter is not mounted. Provide a method of determining no mounting.
According to an aspect of the present invention, it is possible to know whether or not the humidification filter is installed without disassembling the natural humidifying air cleaner.
According to another aspect of the present invention, by allowing the user to know that the humidification filter is not equipped with a natural humidifying air purifier, it is possible to quickly install the humidification filter, thereby maintaining a humid indoor environment This can help improve the living environment.
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. Shapes and sizes of the elements in the drawings may be exaggerated for clarity, elements denoted by the same reference numerals in the drawings are the same elements.

FIG. 5 is a graph comparing pulse signals generated by a motor when the humidification filter is not installed in the natural humidifying air purifier of the present invention (a) and when the humidification filter is mounted (b). As shown in FIG. 5, the motor repeatedly generates the same pulse signal while rotating the fan. In this case, the duty ratio is changed when the normal clean mode and the humidified clean mode are set.
When the natural humidifying air purifier is set to the normal clean mode as shown in (a), the duty ratio is smaller than when it is set to the humidified clean mode as shown in (b). For example, the duty ratio of (a) may be expressed as Equation 1, and the duty ratio of (b) may be expressed as Equation 2. Here, the plurality of pulse signals generated by the motor in the same clean mode have the same magnitude and period.
It can be seen from Equations 1 and 2 that the duty ratio is higher in the humidified clean mode than in the normal clean mode.
When the humidification filter is installed, the differential pressure is generated because air passes through the humidification filter, and the rotational speed of the motor is reduced due to the generation of the differential pressure. Therefore, the rotational speed of the motor in the humidified clean mode is different from the rotational speed of the motor in the normal clean mode.
At this time, since the duty ratio of the pulse signal generated by the motor is increased to compensate for the reduction in the rotational speed of the motor, the duty ratio of the pulse signal generated by the motor in the humidified clean mode is determined by the pulse signal generated by the motor in the normal clean mode. There is a difference with the duty ratio.
From this fact, it is determined that the humidification filter is not installed if the rotational speed of the motor and the duty ratio of the pulse signal are within a certain range compared with the normal clean mode when the natural humidifying air purifier is set to the humidifying clean mode.

Referring to FIG. 6 together with FIGS. 2 and 3, a method of determining whether a humidification filter is not mounted in a natural humidifying air cleaner is as follows.
