PROBLEM TO BE SOLVED: To efficiently introduce a smoke or the like of a cigarette generated near a suction port with a simple constitution. SOLUTION: Louvers 50 are movable to a guiding position projected forward of a suction port opened at a front surface of a cabinet 11 from a storage position to be stored in a louver storage unit 48. When a mode set button 64 is pressed in the state that the louvers 50 are disposed in a storage position to turn a latch member 85 from a locking position to a releasing position, the louvers 50 are moved to the guiding position by an urging force of a spirally coiled spring 58. When a suction fan in the cabinet 11 is rotated in this state, a smoke or the like of a cigarette rising and diffusing near the suction port of the cabinet 11 can be efficiently sucked. |
