That is, the upper end of the light source 181 may be positioned below the upper surface of the mounting portion 171 . Accordingly, damage to the light source 181 by the lower frame 4a of the filter 4 can be prevented in the process of assembling the filter 4 to the mounting portion 171 described above with reference to FIG. 13 .

Also, the light source 181 may provide light to the fan 6 . For example, light from the light source 181 may reach the inner circumferential surface of the bell mouth 6f, that is, the inlet of the fan 6. For example, the light source 181 may provide light in an ultraviolet wavelength range. For example, the light source 181 may be a UVC LED or a UVC lamp providing light having a wavelength of 100 to 280 nm. Accordingly, the light of the light source 181 can sterilize bacteria or microorganisms present in the fan 6 or in the air passing through the fan 6 . In addition, light from the light source 181 can sterilize bacteria or microorganisms present in the filter 4 or in the air passing through the filter 4 .

For example, the control unit may be mounted on the board 180 and may be electrically connected to the board 180 and the light source 181 . For another example, the control unit may be located inside the housing 140, may be spaced apart from the board 180, and may be electrically connected to the board 180 and the light source 181. In this case, the controller detects on-off of the top switch (183, see FIG. 17), the first switch (184, see FIG. 21), and the second switch (185, see FIG. 22). can

In addition, when at least one of the top switch 183, the first switch 184, and the second switch 185 is in an off state, the controller may stop the operation of the light source 181. That is, when the first case 191 is separated from the housing 140, the second case 192 is separated from the housing 140, or the filter 4 is separated from the supporter 170, the controller controls the light source 181 operation can be stopped.

In addition, when the top switch 183, the first switch 184, and the second switch 185 are all turned on, the controller can operate the light source 181. That is, when the filter 4 is seated on the supporter 170 and the first case 191 and the second case 192 are coupled to the housing 140, the controller can operate the light source 181.

Accordingly, the control unit operates the light source 181 to sterilize the fan 6 when the leakage of light from the light source 181 to the outside can be blocked by the filter 4 and the cases 191 and 192. can In other words, when the filter 4 or the cases 191 and 192 are separated from the blower, the control unit stops the operation of the light source 181 to fundamentally block the outflow of light.

Referring to FIG. 23 , the light source 181 may be positioned in the hole 171a (see FIG. 14 ) of the depression 171b. The light source 181 may provide light to the fan 6 and/or the filter 4 in response to its own irradiation angle. Alternatively, a lateral side of the recessed portion 171b may be positioned in a light path of the light source 181 to limit an irradiation range of the light source 181 .

Referring to FIGS. 24 and 25 , the light source 181 may be located in the hole 171a of the depression 171b, and the rib 171c may be located in the light path of the light source 181. The rib 171c can adjust the path of light and protect the light source 181 . The rib 171c may be referred to as a light guide or a shield.

The rib 171c may protrude toward the fan 6 from the depression 171b and may extend along the circumference of the light source 181 . An inner side of the rib 171c may contact or be adjacent to the circumference of the light source 181 . The rib 171c may have a shape corresponding to the cross section of the light source 181 . If the cross section of the light source 181 is circular, the rib 171c may have a hollow cylinder shape. If the cross section of the light source 181 is a rectangle, the rib 171c may have a hollow square barrel shape. The central axis of the rib 171c may be parallel to the vertical direction. An inner side of the rib 171c may define a boundary of the hole 171a of the depression 171b.

Referring to FIG. 24 , for example, the length 171cl of the rib 171c protruding upward from the top of the light source 181 may be greater than the diameter 181t or width 181t of the light source 181 . In addition, the upper end of the rib 171c may be located higher than the first side 171b1. The length 171cl may be referred to as a protrusion height 171c1. The rib 171c may be located in a light path of the light source 181 . The rib 171c may adjust the light path of the light source 181 so that the light of the light source 181 can be intensively irradiated to the fan 6 (refer to the dotted line arrow in FIG. 24 ). That is, the irradiation range of the light source 181 may be limited by the rib 171c.

Accordingly, the rib 171c may minimize light from the light source 181 being provided to the outside of the filter 4 or the case 190 . On the other hand, according to the embodiment, regardless of whether the filter 4 is mounted on the blower (ie, even when the filter 4 is not mounted on the blower), the light of the light source 181 in operation is emitted from the case 190 It is possible to minimize the leakage to the outside through the suction hole (3a, see FIG. 13).

For another example with reference to FIG. 25 , the length 171cl of the rib 171c protruding upward from the top of the light source 181 is substantially the same as the diameter 181t or width 181t of the light source 181, or may be smaller than this. In addition, the upper end of the rib 171c may be located closer to the bottom than the top of the recessed part 171b, and the light path of the light source 181 is closer to the lateral side of the recessed part 171b than the rib 171c. may be more affected by The length 171cl may be referred to as a protrusion height 171cl. The rib 171c may be located in a light path of the light source 181 .

Accordingly, the rib 171c may adjust the light path of the light source 181 so that the light of the light source 181 may be irradiated to the fan 6 and the filter 4 . In addition, the rib 171c may limit the irradiation range of light so that the light of the light source 181 can be provided to the upper side of the lower frame 4a by the recessed portion 171b (refer to the dotted line arrow in FIG. 25). . That is, the lateral side of the depression 171b may be located in the light path of the light source 181 adjusted by the rib 171c. In this case, the sterilization rate of the fan 6 and the filter 4 by light from the light source 181 may be increased.
