Alternatively, the ventilation tube 400 communicates with the suction bin 700 through a communicating tube passing through a sidewall in a radial direction thereof, and the suction hose 420 communicates with the suction bin 700 through a sidewall in an axial direction thereof. In this way, since the suction fan 710 is also a centrifugal fan, the ventilation pipe 400 is connected to the suction chamber 700 through the connection pipe passing through the radial side wall thereof, so that the introduced outdoor air flows into the ventilation pipe 400 through the connection pipe more smoothly, and the outdoor air in the suction hose 420 is sucked by the axial air inlet end of the suction fan 710.
