Wall box and ventilation system comprising a wall box

Abstract

wherein K indicates an area of an enveloping circle with smallest possible radius, which circle completely conceals the cross section of the interior. The flap of the at least one flap arrangement has at least in an open position a flap contour which in regions adjacent to a pivot axis is adapted to a cross-sectional contour of the interior in the respective region adjacent to the pivot axis.

What is claimed is: 
     
         1 . 1. A wall box ( 5 ) for a ventilation system ( 1 ), comprising
   1.1 a housing ( 10 ) delimiting an interior ( 9 ) and having   1.1.1. an inlet ( 11 ) for an air stream and   1.1.2. an outlet ( 12 ) for an air stream,   1.1.3. wherein a through-flow region ( 18 ) connects the inlet ( 11 ) and the outlet ( 12 ) in a flow direction ( 19 ), and comprising     1.2. at least one flap arrangement ( 20 ,  21 ) having a flap ( 23 ) arranged on a suspension mounting ( 22 ),   1.3. wherein the flap ( 23 ) of the at least one flap arrangement ( 20 ,  21 ) is pivotable about a pivot axis ( 26 ) defined by the suspension mounting ( 22 ) between a closing position, which tightly closes off the through-flow region ( 18 ), and an open position,   1.4. wherein, for an area A of a cross section of the interior ( 9 ) perpendicular to the flow direction ( 19 )
   A/K>2/π,
 
   wherein K indicates an area of an enveloping circle with smallest possible radius, which circle completely covers the cross section of the interior ( 9 ),   1.5. wherein the flap ( 23 ) of the at least one flap arrangement ( 20 ,  21 ) has at least in the open position a flap contour ( 29 ) which in regions adjacent to the pivot axis ( 26 ) is adapted to a cross-sectional contour ( 16 ) of the interior ( 9 ) in the respective regions adjacent to the pivot axis ( 26 ).   
     
     
         2 . The wall box ( 5 ) according to  claim 1 , wherein the cross section of the interior ( 9 ) has substantially the shape of one of the group comprising a polygon having at least five corners and a circle. 
     
     
         3 . The wall box ( 5 ) according to  claim 1 , wherein the flap ( 23 ) of the at least one flap arrangement ( 20 ,  21 ) is constructed in one piece. 
     
     
         4 . The wall box ( 5 ) according to  claim 1 , wherein the flap ( 23 ) of the at least one flap arrangement ( 20 ,  21 ) is pivotable, purely mechanically, from the closing position into the open position. 
     
     
         5 . The wall box ( 5 ) according to  claim 1 , wherein the pivot axis ( 26 ) of the at least one flap arrangement ( 20 ,  21 ) is aligned horizontally and arranged in an upper half of the cross section of the interior ( 9 ). 
     
     
         6 . The wall box ( 5 ) according to  claim 5 , wherein the pivot axis ( 26 ) of the at least one flap arrangement ( 20 ,  21 ) is arranged on one of the group comprising an upper margin of the through-flow region ( 18 ) and above this. 
     
     
         7 . The wall box ( 5 ) according to  claim 1 , wherein the flap ( 23 ) of the at least one flap arrangement ( 20 ,  21 ) bears in the open position, in the regions adjacent to the pivot axis ( 26 ), at least partially against the housing ( 10 ). 
     
     
         8 . The wall box ( 5 ) according to  claim 1 , comprising at least two flap arrangements ( 20 ,  21 ), which are spaced apart in the flow direction ( 19 ). 
     
     
         9 . The wall box ( 5 ) according to  claim 8 , wherein a spacing of the pivot axes ( 26 ) of two adjacent flap arrangements ( 20 ,  21 ) is at least dimensioned such that the flaps ( 23 ) of different flap arrangements ( 20 ,  21 ) in the open position have no overlap in the flow direction ( 19 ). 
     
     
         10 . The wall box ( 5 ) according to  claim 1 , wherein a flap arrangement ( 21 ), disposed adjacent to the outlet ( 12 ), of the at least one flap arrangement ( 20 ,  21 ) is arranged such that its flap ( 23 ) in the open position protrudes from the outlet ( 12 ). 
     
     
         11 . The wall box ( 5 ) according to  claim 1 , wherein the suspension mounting ( 22 ) of the at least one flap arrangement ( 20 ,  21 ) is constructed as a capsule-pin suspension mounting. 
     
     
         12 . The wall box ( 5 ) according to  claim 1 , wherein the flap ( 23 ) of the at least one flap arrangement ( 20 ,  21 ) has an insulation layer. 
     
     
         13 . The wall box ( 5 ) according to  claim 1 , comprising a connecting socket ( 13 ) in the region of the inlet ( 11 ) for connection to a ventilation system ( 1 ).
