Abstract
A hood device for grill comprises a hood, a telescoping tubing, a filter assembly, a grease cup, and an external fan. The hood partially covers a grill at a first elevated vertical position and collects smokes from the grill. The telescoping tubing extends from the hood and is configured for ventilating, and telescoping between the first and second positions. The filter assembly is disposed at a lower end of the telescoping tubing, and comprises filter with concentric and cylindrical layers. The grease cup is for collecting grease from the filter. The fan is for building up an ascending air current inside the telescoping tubing. A velocity of the ascending air current is determined according to the first elevated vertical position, a ratio of a diameter of the hood to a diameter of the grill, and a surface temperature of the grill.
