Extractor hood

Abstract

An extractor hood includes a housing with a fan disposed therein and an extraction opening for the entry of fumes into the extractor hood on the bottom of the extractor hood. The extractor hood has an air outlet gap on the top of the extractor hood in the edge region of the extractor hood. The air outlet gap is adjacent to a surface that is arched in the direction of the bottom of the extractor hood.

       14 . An extractor hood comprising:
 a housing with a fan arranged therein;   an extraction opening for the entry into the extractor hood of fumes from a fumes generating source, the extraction opening having a side of the extractor hood toward the fumes generating source; and   at least one air outlet gap on another side of the extractor hood opposite the side of the extractor hood toward the fumes generating source, the air outlet gap being located at an edge region of the extractor hood that is adjacent to a curved surface extending in a direction toward the side of the extractor hood toward the fumes generating source.   
   
   
       15 . The extractor hood as claimed in  claim 14 , wherein the air outlet gap is configured such that an airflow through the gap is limited in a direction that has a vertical direction component greater than zero. 
   
   
       16 . The extractor hood as claimed in  claim 14 , wherein the another side of the extractor hood in which the air gap is provided lies in a plane the same as, or offset in parallel to, a plane in which the highest point of the curved surface is located and, in particular, lies in a horizontal plane the same as, or offset in parallel below, a plane in which the highest point of the curved surface is located. 
   
   
       17 . The extractor hood as claimed in  claim 14 , wherein the air outlet gap is provided at an air guidance duct extending from the fan of the extractor hood to at least one edge region of the extractor hood. 
   
   
       18 . The extractor hood as claimed in  claim 14 , wherein the curved surface delimits a lateral outer surface of the extractor hood and, in particular, a lateral outer surface of the extractor hood at the outer edge of the extractor hood. 
   
   
       19 . The extractor hood as claimed in  claim 14 , wherein the gap width of the air outlet gap is configured as a function of the radius of curvature of the curved surface. 
   
   
       20 . The extractor hood as claimed in  claim 14  and further comprising an edge element, especially a tubular edge element, that forms the curved surface. 
   
   
       21 . The extractor hood as claimed in  claim 14 , wherein the air outlet gap is delimited by the curved surface and a cover of the another side of the extractor hood and the cover of the another side of the extractor hood lies in or below the plane of the highest point of the curved surface. 
   
   
       22 . The extractor hood as claimed in  claim 21 , wherein the cover of the another side of the extractor hood delimits a cover of a vapor shield of an extractor hood. 
   
   
       23 . The extractor hood as claimed in  claim 14 , wherein the curved surface has a transition side at which it meets the side of the extractor hood toward the fumes generating source and the extraction opening of the extractor hood is arranged offset toward the another side of the extractor hood in relation to the transition side of the curved surface and, in particular, the extraction opening of the extractor hood is arranged offset upwards in relation to the lower side of the curved surface. 
   
   
       24 . The extractor hood as claimed in claimed  23 , wherein the extractor hood has at least one lateral profile, the lower edge of which lies in a plane in which the transition side of the curved surface lies and, in particular, the lower edge of the lateral profile lies in the plane of the bottom of the curved surface. 
   
   
       25 . The extractor hood as claimed in  claim 17 , wherein at least one baffle element is provided in the air guidance duct at the air outlet gap. 
   
   
       26 . The extractor hood as claimed in  claim 14 , wherein at least one control element is arranged on the curved surface.
