Exhaust hood with a chimney housing and double-layered vapor-collecting canopy

Abstract

An exhaust hood is provided having a chimney housing and a double-layered vapor-collecting canopy secured to the chimney housing. The vapor-collecting canopy is near a suction zone of the exhaust hood and includes an inner panel and an outer panel. The inner panel has a vapor-collecting surface and the outer panel extending substantially parallel to the vapor-collecting surface. The inner panel and the outer panel are fixed relative to each other in a mounted position by at least one fastening arrangement. A portion of the inner panel and the outer panel are spaced apart in a direction perpendicular to the vapor-collecting surface forming an accommodation space for circuitry elements of the exhaust hood.

1 . An exhaust hood, comprising:
 a chimney housing;   a double-layered vapor-collecting canopy disposed on the chimney housing, the vapor-collecting canopy including an inner panel and an outer panel, the inner panel having a vapor-collecting surface and the outer panel extending substantially parallel to the vapor-collecting surface,   wherein the inner panel and the outer panel are fixed relative to each other in a mounted position by at least one fastening device, a portion of the inner panel and the outer panel being spaced apart in a direction perpendicular to the vapor-collecting surface forming an accommodation space for circuitry elements of the exhaust hood.   
   
   
       2 . The exhaust hood recited in  claim 1 , wherein the accommodation space is configured to receive an electrical controller of the exhaust hood. 
   
   
       3 . The exhaust hood recited in  claim 2 , wherein the accommodation space includes an enlarged portion forming a wiring compartment and extending to a connection area of the vapor-collecting canopy and the chimney housing. 
   
   
       4 . The exhaust hood recited in  claim 1 , wherein the accommodation space extends substantially over an overlap region that does not include a first attachment region where the inner and outer panels are joined together by the fastening device. 
   
   
       5 . The exhaust hood recited in  claim 1 , wherein a cross-sectional profile of the inner panel at an end of the vapor-collecting canopy facing away from the chimney housing includes a portion set back toward the outer panel and sloping downward toward the outer panel, regardless of a position of the vapor-collecting canopy. 
   
   
       6 . The exhaust hood recited in  claim 1 , wherein the inner and outer panels each include, in the first attachment region, a three-dimensional profile extending toward the suction zone, the three-dimensional profiles of the inner and outer panels being similar in shape. 
   
   
       7 . The exhaust hood recited in  claim 6 , wherein the three-dimensional profiles each have a triangular cross-section. 
   
   
       8 . The exhaust hood recited in  claim 6 , wherein at least one of the three-dimensional profiles is formed as an angularly bent portion of at least one of the inner panel and the outer panel. 
   
   
       9 . The exhaust hood recited in  claim 6 , wherein the vapor-collecting canopy is configured as two-pieces and the inner and outer panels have a second attachment region disposed at an opposite end of the vapor-collecting canopy from the first attachment region. 
   
   
       10 . The exhaust hood recited in  claim 9 , wherein the inner and outer panels are separably joined together in the second attachment region by a tongue-and-opening connection. 
   
   
       11 . The exhaust hood recited in  claim 1 , wherein the vapor-collecting canopy is near a suction zone of the exhaust hood. 
   
   
       12 . The exhaust hood recited in  claim 2 , wherein the accommodation space extends substantially over an overlap region that does not include a first attachment region where the inner and outer panels are joined together by the fastening device. 
   
   
       13 . The exhaust hood recited in  claim 3 , wherein the accommodation space extends substantially over an overlap region that does not include a first attachment region where the inner and outer panels are joined together by the fastening device. 
   
   
       14 . The exhaust hood recited in  claim 2 , wherein a cross-sectional profile of the inner panel at an end of the vapor-collecting canopy facing away from the chimney housing includes a portion set back toward the outer panel and sloping downward toward the outer panel, regardless of a position of the vapor-collecting canopy. 
   
   
       15 . The exhaust hood recited in  claim 3 , wherein a cross-sectional profile of the inner panel at an end of the vapor-collecting canopy facing away from the chimney housing includes a portion set back toward the outer panel and sloping downward toward the outer panel, regardless of a position of the vapor-collecting canopy. 
   
   
       16 . The exhaust hood recited in  claim 4 , wherein a cross-sectional profile of the inner panel at an end of the vapor-collecting canopy facing away from the chimney housing includes a portion set back toward the outer panel and sloping downward toward the outer panel, regardless of a position of the vapor-collecting canopy. 
   
   
       17 . The exhaust hood recited in  claim 2 , wherein the inner and outer panels each include, in the first attachment region, a three-dimensional profile extending toward the suction zone, the three-dimensional profiles of the inner and outer panels being similar in shape. 
   
   
       18 . The exhaust hood recited in  claim 3 , wherein the inner and outer panels each include, in the first attachment region, a three-dimensional profile extending toward the suction zone, the three-dimensional profiles of the inner and outer panels being similar in shape.
