PURPOSE:To prevent the formation of oil-drip while delaying the progress of loading due to oil-drip, by obviating the generation of oil-drip by mounting a grease filter for removing oil portions in soot at the inside of a grill formed in a specified shape in this ventilating device. CONSTITUTION:A motor 5 and a blade 6 directly coupled with a motor shaft are installed to a body case 1, and indoor air is sucked through a grill 12, a grease filter 11 and a suction port 8 of a fan cover by the revolution of the blade 6, and exhausted to the outside from an exhaust port 2 after removing oiliness portions in air by means of said filter 11. In this ventilating device constituted in this manner, said grill 12 is formed by a surrounding receiving surface 15 of an area outer surface indicated by dimensions L3 slightly smaller than the effective area of the filter 11, area displayed by dimensions L2, as compared to the effective area of the filter 11, a central plane portion 16 and an inclined plane portion 17 that produces space A exhibited by dimensions L4, and ventilating holes 18 are mounted to the portions 16, 17. |
