Referring to FIG. 4 , the suction force generated by the station suction device 131 means that the dirt of the dust collection chamber 16 is sucked into the suction port 201 , and the dirt sucked through the suction port 201 is in communication with the suction port 201 . An air flow transferred to the guide unit 210 may be formed. The direction of such an airflow may be defined as a suction force action direction (D1', see FIG. 8). The suction force action direction D1 ′ may be defined as one direction from the suction port 201 toward the connection hose fastening portion 202 among the horizontal directions D1 , which are directions in which the guide portion 210 extends.

At this time, as shown in FIG. 4 , the lower door 15a of the dust collection chamber 16 opened toward the suction port 201 and one side 210a of the guide part 210 from which the guide part 210 starts to extend. In between, a vortex (Vortex) may be generated separately from the airflow in which the dirt sucked through the suction port 201 is transferred to the guide unit 210 communicating with the suction port 201 . A region where such a vortex occurs may be defined as a vortex region (V) below.

Since the vortex is formed, dirt remains in the area between the lower door 15a of the dust collection chamber 16 and one side 210a of the guide part 210 from which the guide part 210 starts to extend. In addition, due to the formation of the vortex, the airflow in which the dirt sucked through the suction port 201 is transferred to the guide unit 210 communicating with the suction port 201 is unstable.

Therefore, the vortex region V from the one side 210a from which the guide part 210 starts to extend, separately from the airflow that transports the dirt sucked into the suction port 201 to the guide unit 210 communicating with the suction port 201 . ) to suppress the generation of the above-described vortex by forming a flow of external air toward the ), thereby removing residual dust and stabilizing the airflow for transporting dirt.

Hereinafter, the formation position of the ventilation hole 300 provided in the guide part 210 will be described in detail. As described above, the guide unit 210 may be formed by contacting the upper guide housing 211 and the lower guide housing 212 to each other.

The ventilation hole 300 may be formed at a height spaced apart from the bottom surface of the guide plate 213 by a predetermined distance L1 among the inclined surfaces of the second fence part 214b.

As shown in FIGS. 8 to 10 , when the suction force starts to be generated by the station suction device 131 , the outside air staying in the hollow part 214c begins to extend through the vent 300 , the guide part 210 . A flow of outside air may occur in a direction D3 from one side 210a of the guide part 210 toward the vortex region V. In addition, by forming the inclined surface, dirt can easily flow down to the inside of the guide part 210 . In addition, since the vent 300 is formed at a height spaced apart from the bottom surface of the guide plate 213 by a predetermined distance L1 , dirt may not easily flow out through the vent 300 .

11 is an enlarged view of a portion in which a ventilation hole is formed among a lower guide housing of a robot cleaner station according to another embodiment of the present invention. 12 is a view of FIG. 11 viewed from another side. 13 is a cross-sectional view of a cleaner seating part of a robot cleaner station according to another embodiment of the present invention.

The recessed part 214d may be provided in a structure concavely recessed from the inclined surface of the second fence part 214b of the fence part 214 . In this case, the ventilation holes 300 may be formed on both sides of the recessed portion 214d. Specifically, a pair of vents 300 may be formed to face each other.

11 to 13 , when the suction force starts to be generated by the station suction device 131 , the outside air staying in the hollow part 214c is depressed from both sides of the recessed part 214d through the ventilation hole 300 . It may flow in the direction D5 toward the center of the part 214d.

The flow of outside air flowing in the direction D5 from both sides of the recessed part 214d toward the center of the recessed part 214d is suctioned by the station suction device 131, and the middle of the recessed part 214d. Due to the structure that joins at the point, the guide part 210 again flows in the direction D3 from one side 210a of the guide part 210 starting to extend toward the vortex region V.

14 is an enlarged view of a portion in which a ventilation hole is formed among the upper guide housing of the robot cleaner station according to another embodiment of the present invention. 15 is a cross-sectional view of a cleaner seating part of a robot cleaner station according to another embodiment of the present invention.

Specifically, the vent 300 may be formed in the guide sidewall 215 corresponding to one side 210a of the guide part 210 . The ventilation hole 300 may be formed at a height spaced apart from the bottom surface of the guide plate 213 by a predetermined distance L1 so as to be positioned above the upper end of the fence unit 214 .

14 to 15 , when the suction force starts to be generated by the station suction device 131 , the outside air remaining in the space between the upper cover 120a and the base plate 120b passes through the vent 300 . The flow of outside air may occur in a direction D3 from one side 210a of the guide part 210 from which the guide part 210 begins to extend toward the vortex region V. In addition, by forming the inclined surface, dirt can easily flow down to the inside of the guide part 210 . In addition, since the vent 300 is formed at a height spaced apart from the bottom surface of the guide plate 213 by a predetermined distance L1 , dirt may not easily flow out through the vent 300 .
