Abstract
The object of this invention is to provide a range hood. The hood body (20) of the range hood consists of a lower plate (22) having perforations for sucking air from the kitchen into the hood body, with an inward locking flange (23, 23′) formed along the top edge of each sidewall of the lower plate. Two guide panels (21, 21′), each having a locking part, are assembled with the lower plate (22) by an engagement of their locking parts with the inward locking flanges. A double absorption filter (30) is installed inside the hood body so as to remove oil, dust and other impurities from exhaust air by means of an air vortex effect. The range hood also has a hood cover (10), an exhaust duct (11), a fan motor (13), an exhaust fan (12), and a ventilation duct (14) to discharge exhaust air to the atmosphere.
