A range hood with a motor housing having top and bottom surfaces and angled walls, so as to facilitate the travel of entrained air drawn in through the air inlets by the, operation of the fans. The top surface is larger than the bottom surface and angling, of the walls is greatest towards the rear of the housing. A ventilation hole is located in, the rear of the top surface. Because the ventilation hole is set more rearwardly in, relation to the air inlets the inlets may be positioned further forward in the range hood, body as compared to the motor housings of the prior art thereby increasing the suction area over a cooking surface.

Why it's free to use
- Filed October 3, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 3, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 3, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
