PURPOSE:To make it possible to freely select the exhaustion direction in correspondence to the conditions of the installation position by constituting the fan by three parts, that is, a main body case, a control case, and a case for natural ventilation and varying the fitting positons and the fitting directions of these cases. CONSTITUTION:In a case where the exhaust hole and suction hole at the back sides of the intallation position, the main body case 1, control case 11 and case 15 for natural ventilation are assembled as shown in the drawing, and an exhaust port member 8 and an inlet port member 21 are arranged at the back surface side. When a driving switch 12 is turned ''ON'', smokes and the like from the range are exhausted through exhaust ports 6 and 8 by an exhausting fan device. Fresh air enters into the room from an outlet port 16 via the inlet port member 21 and the case 15. Further, in the case of exhausting air rightwardly, the control case 11 is fitted to the side surface portion 1d of the main body case 1, and the right side surface portion 15d of the natural ventilation case 15 is brought into abutment with the side surface portion 1e. |
