PURPOSE:To automatically replenish the cleaning liquid reservoir with the cleaning liquid while a venting fan is being operated by providing a liquid level switch in the cleaning liquid reservoir located in the bottom of the main body, and providing a solenoid valve, which is interlocked to the liquid level switch, in a pipe connecting a cleaning liquid tank with the cleaning liquid reservoir. CONSTITUTION:Oily particles in the oily smoke are separated by the inertial collision and stick to buffle plates 8a, 8b, 8c and the inner wall of the main body 3, and the cleaned exhaust air is discharged from an air vent 7. While the air is discharged, both a solenoid valve 29 and a pilot lamp 19 are connected to the power source via a liquid level switch 34. When there is too little cleaning liquid in a cleaning liquid reservoir 11, the liquid level switch 34 is turned ON, the pilot lamp 19 is illuminated, and the solenoid valve 29 is opened to allow the cleaning liquid to be supplied from a cleaning liquid tank 15 through a feed pipe 28 to the cleaning liquid reservoir 11. |
