Referring to FIGS. 1 and 2 , the case 110 may form a passage through which one side and the other side are open. For example, one side may be in a direction opposite to the direction in which air flows. For example, referring to FIG. 1 (a) in detail, when air flows from the 5 o'clock direction to the 11 o'clock direction, one side may be the 5 o'clock direction. Accordingly, the other side may be in the 11 o'clock direction. Also, for example, the case 110 may be provided as a cylindrical member having a circular cross section.

Referring to Figures 1 and 2, the filter member 120 may be disposed with respect to the passage of the case 110 to filter air passing from one side to the other side. The filter member 120 may be provided as, for example, a pre-filter that filters out large dust. Also, for example, the filter member 120 may be provided in a circular shape.

Also, for example, referring to FIG. 2 , the device 100 may include a frame 121 supporting the filter member 120 .

Referring to FIG. 1 , the filter driving unit 130 may be installed with respect to the case 110 to rotate the filter member 120 so as to enable mode conversion to one of a filter mode and a cleaning mode. Referring to (a) of FIG. 1 , the filter mode may be a mode in which one surface of the filter member 120 faces one side and the other surface faces the other side. Also, referring to (c) of FIG. 1 , the cleaning mode may be a mode in which one surface of the filter member 120 faces the other side and the other surface faces the other side. For example, referring to (b) of FIG. 1 , the filter driving unit 130 may rotate the filter member 120 in order to switch from the filter mode to the cleaning mode, and also, as another example, the cleaning mode. In order to switch to the filter mode, the filter member 120 may be rotated. For example, when switching modes, the filter member 120 is preferably rotated 180 degrees.

For example, the filter driving unit 130 may be equipped with a motor.

Referring to FIGS. 1 and 2 , the apparatus 100 may include a brush unit 140 and a brush driving unit 150 .

The brush unit 140 may be provided to be rotatable in a state in which a plurality of bristle members are in contact with one surface of the filter member 120 in the cleaning mode. For example, referring to FIGS. 1(a) and 2 , the brush unit 140 is provided along the other surface of an extension member extending radially about a rotational axis and one surface of the filter member 120. It may include a plurality of parent members in contact with. For example, the extension member may be extended in two prongs, as shown in FIGS. 1 (a) and 2, but is not limited thereto, and may be provided to extend in two or more prongs.

Also, the brush driving unit 150 may provide driving force for rotating the brush unit 140 in the cleaning mode. The brush driving unit 150 is disposed on the other side of the filter member 120 and may be connected to share a rotating shaft with the brush unit 140 .

It may be provided in a propeller shape to be. For example, the propeller shape may be a bifurcated shape. The number of prongs of the propeller may correspond to the number of extension members of the brush unit 140 described above. In addition, the direction in which the propeller extends in the radial direction (radial) is set to correspond to (same as) the direction in which the extension member of the brush unit 140 extends, thereby reducing obstruction of the flow of air passing through the filter member 120 ( can be minimized).

For example, such a propeller shape may be a shape that does not respond to the movement of air passing from one side to the other side (non-rotating) in a filter mode (a state in which the other side faces the other side). In addition, even in the case of a propeller shape that rotates in the filter mode, since the extension member of the brush unit 140 is located (covered) on one surface side corresponding to the position of the propeller in the filter mode, the direct influence of air movement is reduced. Because of this, the propeller may not be rotated because it does not receive direct air movement.

Accordingly, in the apparatus 100, since the propeller does not rotate in the filter mode and rotates only in the cleaning mode, problems such as loss of air inflow or wear of the filter may not occur.

The apparatus 100 includes a brush unit 140 and a brush driving unit 150, so that the brush driving unit 150 is provided in a propeller shape that rotates in response to the movement of air passing from one side to the other in the cleaning mode. Through this, the brush unit 140 is rotated together, and as the brush unit 140 rotates, foreign substances (dust) adsorbed on the filter member 120 are shaken off, removing foreign substances (dust), increasing the ventilation efficiency of the filter, , the replacement cycle of the filter member 120 can be extended.
