Motor housing for a range hood

Abstract

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.

What is claimed is:  
     
         1 . A motor housing for a range hood wherein said motor housing comprises top, bottom and perimeter side surfaces and having a front and a rear, wherein said top surface overlaps said bottom surface.  
     
     
         2 . The motor housing of  claim 1  wherein said overlap is at said rear of said motor housing.  
     
     
         3 . The motor housing of  claim 1 , wherein at said front, said perimeter side surface is substantially perpendicular to said top surface and said bottom surface.  
     
     
         4 . The motor housing of  claim 3 , wherein at said rear, said perimeter side surface is substantially angled in relation to said top surface and said bottom surface.  
     
     
         5 . The motor housing of  claim 3 , wherein at said rear, said perimeter side surface is substantially angled in relation to said top surface and substantially perpendicular in relation to said bottom surface.  
     
     
         6 . The motor housing of  claim 4  or  5 , wherein said angling of said perimeter side surface in relation to said top and bottom surface commences at a transition point between said front and said rear.  
     
     
         7 . The motor housing of  claim 6 , wherein said angling increases from front to rear.  
     
     
         8 . The motor housing of  claim 1  or  7  further comprising a ventilation hole in said top surface.  
     
     
         9 . The motor housing of  claim 8  wherein a rear of said ventilation hole is disposed rearwardly of said bottom surface of the motor housing.  
     
     
         10 . A motor housing for a range hood wherein said motor housing comprises top, bottom and perimeter side surfaces and having a front and a rear, wherein said top surface has a surface area larger than a surface area of said bottom surface.  
     
     
         11 . A motor housing for a range hood wherein said motor housing comprises top, bottom and perimeter side surfaces and having a front and a rear, wherein at said rear, said perimeter side surface is substantially angled in relation to said top surface and said bottom surface.
