Fume Extraction Hood

Abstract

The present invention relates to a fume extraction hood ( 2 ) having an exhaust opening ( 4 ) for leading away exhaust air (A) and an inlet opening ( 6 ) for feeding inlet air (Z), disposed adjacent to the exhaust opening ( 4 ). In order to achieve an inlet air guide, by means of which cooking vapors can be effectively captured and fed to the exhaust opening, the invention proposes that the inlet opening ( 6 ) is disposed and implemented so that the inlet air flow ( 8 ) flowing out of the inlet opening ( 6 ) in a direction oriented opposite to the flow direction of an exhaust gas flow ( 10 ) flowing into the exhaust opening ( 4 ), and the exhaust air flow ( 10 ) is deflected sideways via an extraction path (F).

1 .- 10 . (canceled) 
     
     
         11 . A fume exhaustion hood comprising:
 an exhaust opening that exhausts exhaust air;   an inlet air opening that supplies inlet air and is arranged adjacent to said exhaust opening;   wherein said inlet air opening is arranged and configured such that an inlet air flow exiting from said inlet air opening is oriented in a direction that is opposite to a flow direction of an exhaust air flow flowing toward said exhaust opening and laterally flanks the exhaust air flow across a conveying stretch.   
     
     
         12 . The fume exhaustion hood according to  claim 11 , wherein a blowing direction, a blowing volume, and a blowing speed of the inlet air flow is matched to the exhaust air flow such that, in operation of the fume exhaustion hood at a spacing to the fume exhaustion hood, a standing air swirl is formed that has a rotational direction that is oriented from an exterior of the fume exhaustion hood toward the exhaust air flow. 
     
     
         13 . The fume exhaustion hood according to  claim 11 , comprising several of said inlet air opening to produce the inlet air flow. 
     
     
         14 . The fume exhaustion hood according to  claim 11 , comprising a lateral wall, wherein the inlet air flow is guided at least sectionwise along said lateral wall. 
     
     
         15 . The fume exhaustion hood according to  claim 14 , wherein said lateral wall has an orientation that, in relation to an outflow direction of the inlet air flow from said inlet air opening, is oriented so as to point away from the exhaust air flow. 
     
     
         16 . The fume exhaustion hood according to  claim 11 , comprising a deflection surface positioned at a spacing from said inlet air opening, wherein said deflection surface deflects the inlet air flow in a direction toward the exhaust air flow. 
     
     
         17 . The fume exhaustion hood according to  claim 11 , comprising an inlet air conveying duct with duct walls ending at said inlet air opening, wherein said ducts walls are shaped in front of said inlet air opening such that an outflow direction of the inlet air flow from said inlet air opening is oriented opposite to the flow direction of the exhaust air flow. 
     
     
         18 . The fume exhaustion hood according to  claim 11 , wherein the volume of the inlet air flow is maximally 40% of the volume of the exhaust air flow. 
     
     
         19 . The fume exhaustion hood according to  claim 11 , wherein a shape and a size of said inlet air opening is adjustable. 
     
     
         20 . The fume exhaustion hood according to  claim 11 , wherein a shape of said inlet air opening is adjustable. 
     
     
         21 . The fume exhaustion hood according to  claim 11 , wherein a size of said inlet air opening is adjustable. 
     
     
         22 . The fume exhaustion hood according to  claim 11 , comprising a valve that conveys a portion of the volume of the exhaust air flow to said inlet air opening.
