Abstract

A gas burner has a fan and a mixing device disposed at the suction side of the fan. The mixing device mixes the air taken in through an intake channel with a gas supplied to the intake channel through a gas inlet to form a gas-air mixture. The mixing device has a housing with an air inlet formed with cutouts for noise reduction.

Claims

1 . A gas burner, comprising:
 a fan having an suction side;   a mixing device disposed at said suction side of said fan, said mixing device having an intake channel for air and said intake channel for air having a gas inlet, said mixing device mixing air taken in through said intake channel for air with a gas supplied through said gas inlet to form a gas-air mixture; and   said mixing device having a housing with an air inlet formed with cutouts for noise reduction.   
   
   
       2 . The gas burner according to  claim 1 , wherein said air inlet is an annular inlet and said cutouts are formed in an annular circumference of said air inlet. 
   
   
       3 . The gas burner according to  claim 2 , wherein said cutouts are formed at regular intervals. 
   
   
       4 . The gas burner according to  claim 1 , wherein said housing of said mixing device is formed in one piece with said air inlet. 
   
   
       5 . The gas burner according to  claim 1 , wherein said air inlet is a separate part connected to said housing of said mixing device. 
   
   
       6 . The gas burner according to  claim 1 , wherein said gas inlet is disposed at right angles to said intake channel for air. 
   
   
       7 . The gas burner according to  claim 6 , wherein said intake channel of said mixing device is a venturi nozzle and said gas inlet is a tubular inlet. 
   
   
       8 . The gas burner according to  claim 6 , wherein said housing of said mixing device has an annular disk configured for connection to said suction side of said fan. 
   
   
       9 . The gas burner according to  claim 8 , wherein said housing of said mixing device, said annular disk, and said gas inlet are formed in one piece. 
   
   
       10 . The gas burner according to  claim 1 , which further comprises a sound suppressor configured to be connected to said air inlet.
