Oven for cooking foods

Abstract

An oven ( 100 ) comprising an oven chamber ( 105 ) for the cooking of foods, heating means ( 125 ) for heating the oven chamber, and a vapor exhaust system ( 155 ) for treating vapors produced in the oven chamber during a food cooking process. The vapor exhaust system comprises: a first region ( 405 ) in fluid communication ( 160,165,170 ) with the oven chamber so as to receive vapors exiting the oven chamber and wherein the vapors are de-moisturized and cooled down; and a second region ( 410 ) downstream the first region and wherein the de-moisturized and cooled down vapors exiting the first region are mixed to hot dry air ( 140 ) before being exhausted to the outside ambient.

1 . An oven ( 100 ) comprising an oven chamber ( 105 ) for the cooking of foods, heating means ( 125 ) for heating the oven chamber, and a vapor exhaust system ( 155 ) for treating vapors produced in the oven chamber during a food cooking process, characterized in that the vapor exhaust system comprises:
 a first region ( 405 ) in fluid communication ( 160 , 165 , 170 ) with the oven chamber so as to receive vapors exiting the oven chamber and wherein the vapors are de-moisturized and cooled down; and   a second region ( 410 ) downstream the first region and wherein the de-moisturized and cooled down vapors exiting the first region are mixed to hot dry air ( 140 ) before being exhausted to the outside ambient.   
     
     
         2 . The oven of  claim 1 , wherein said first region extends vertically. 
     
     
         3 . The oven of  claim 1 , wherein in the first region a tortuous path for the vapors is formed. 
     
     
         4 . The oven of  claim 3 , wherein said tortuous path is a duct comprising a plurality of baffles ( 177 ; 1077 ). 
     
     
         5 . The oven of  claim 4 , wherein at least one of said baffles is hollow and run through a heat-exchange fluid ( 1005 ). 
     
     
         6 . The oven of  claim 3 , wherein a coolant liquid feeding device ( 415 , 420 ) is associated with said first region, arranged for feeding a coolant liquid into the first region for cooling down the vapors. 
     
     
         7 . The oven of  claim 6 , wherein said coolant liquid feeding device comprises at least one liquid feeding nozzle ( 415 ) adapted to spray coolant liquid into said first region in a nebulized form. 
     
     
         8 . The oven of  claim 6 , wherein said coolant liquid feeding device is arranged to cause the coolant liquid to enter into the first region proximate to a top side thereof. 
     
     
         9 . The oven of  claim 6 , wherein said coolant liquid feeding device is connected to an activator adapted to selectively activate said coolant liquid feeding device for selectively feeding the coolant liquid. 
     
     
         10 . The oven of  claim 6 , wherein at least a temperature sensor ( 425 ) is associated with the first region, arranged for sensing the temperature of the vapors entering into the vapors exhaust system. 
     
     
         11 . The oven of  claim 10 , wherein said coolant liquid feeding device is selectively activated based on a sensed temperature of the vapors sensed by said temperature sensor. 
     
     
         12 . The oven of  claim 1 , comprising at least an air propeller ( 180 ) associated with said vapor exhaust system and configured for promoting the exit of vapors from the oven chamber and their flow through the vapor exhaust system. 
     
     
         13 . The oven of  claim 12 , wherein said air propeller comprises an axial or radial fan arranged at the exit of the second region. 
     
     
         14 . The oven of  claim 12 , wherein said air propeller is selectively activatable. 
     
     
         15 . The oven of  claim 1 , wherein said hot dry air comprises air exploited to cool down at least one among a door ( 120 ) of the oven and/or air exploited to cool down internal oven parts subjected to heat up during the oven operation.
