Vapour extraction device and accommodating device for at least one food preparation unit incorporating such a vapour extraction device

Abstract

In order to provide a vapour extraction device comprising at least one air curtain producing device and at least one vapour suction device incorporating at least one vapour suction opening, it is proposed that, by means of the air curtain producing device, there can be produced an air curtain which is so oriented that at least a part of the air stream forming the air curtain impinges on at least one vapour suction opening.

1 . A vapour extraction device, comprising at least one air curtain producing device and at least one vapour suction device incorporating at least one vapour suction opening, wherein by means of the air curtain producing device, there can be produced an air curtain which is oriented in such a way that at least a part of the air stream forming the air curtain impinges on at least one vapour suction opening.  
     
     
         2 . A vapour extraction device in accordance with  claim 1 , wherein at least half of the air stream forming the air curtain is arranged to be sucked through at least one vapour suction opening.  
     
     
         3 . A vapour extraction device in accordance with  claim 2 , wherein substantially all of the air stream forming the air curtain is arranged to be sucked through at least one vapour suction opening.  
     
     
         4 . A vapour extraction device in accordance with  claim 1 , wherein the vapour extraction device comprises at least one fat filter through which passes at least a part of the vapour sucked-in through the at least one vapour suction opening.  
     
     
         5 . A vapour extraction device in accordance with  claim 4 , wherein the vapour extraction device comprises at least one bypass channel through which the vapour being sucked-in through at least one vapour suction opening is removed without passing through a fat filter.  
     
     
         6 . A vapour extraction device in accordance with  claim 5 , wherein the bypass channel has a labyrinthine flow path for separating-out particles contained in the sucked-in vapour.  
     
     
         7 . A vapour extraction device in accordance with  claim 4 , wherein at least a part of the air stream forming the air curtain passes through at least one fat filter.  
     
     
         8 . A vapour extraction device in accordance with  claim 1 , wherein the air curtain producing device comprises at least one air outlet nozzle.  
     
     
         9 . A vapour extraction device in accordance with  claim 8 , wherein the air curtain producing device comprises at least one deflecting element by means of which the air stream emerging from the air outlet opening is diverted.  
     
     
         10 . A vapour extraction device in accordance with  claim 8 , wherein the vapour extraction device comprises at least one straightening element arranged upstream of the air outlet opening for the purposes of distributing the air stream flowing towards the air outlet nozzle uniformly over the nozzle cross sectional area of the air outlet nozzle.  
     
     
         11 . A vapour extraction device in accordance with  claim 10 , wherein the straightening element comprises a perforated plate.  
     
     
         12 . A vapour extraction device in accordance with  claim 1 , wherein the vapour extraction device comprises at least one blower for sucking away the vapours, wherein the blower is connected on the delivery side thereof to the air curtain producing device.  
     
     
         13 . An accommodating device for at least one food preparation unit, comprising at least one vapour extraction device, said vapour extraction device comprising at least one air curtain producing device and at least one vapour suction device incorporating at least one vapour suction opening, wherein by means of the air curtain producing device, there can be produced an air curtain which is oriented in such a way that at least a part of the air stream forming the air curtain impinges on at least one vapour suction opening.  
     
     
         14 . An accommodating device in accordance with  claim 13 , comprising at least one supporting surface for the placement of at least one food preparation unit.  
     
     
         15 . An accommodating device in accordance with  claim 14 , wherein there is provided below the supporting surface a storage space, into which at least one mobile apparatus is moveable.
