Gas burner

Abstract

A gas burner for caravans, boats or vehicles in general includes an injector holder to be applied in correspondence with an opening intended to be made in a hob of a caravan, boat or vehicle in general. The injector holder includes at least one injector connected to at least one gas inlet. The burner also includes a flame spreader which is positioned above the injector holder and includes at least one duct in fluid communication with the injector and with at least one distribution chamber of the combustible mixture, to generate at least one crown of flames. The burner further includes: a lid, resting on said flame spreader, delimiting the distribution chamber of the combustible mixture at the top; locking means to prevent or limit movement between the flame spreader and the lid and means for magnetically connecting the injector holder with the flame spreader and/or the lid.

       means ( 70 ,  80 ) for magnetically connecting the injector holder ( 6 ) with the flame spreader ( 4 ) and/or the lid ( 8 ). 
     
     
         2 . The gas burner according to  claim 1 , wherein said locking means are configured to block both the lateral movement between the flame spreader ( 4 ) and the lid ( 8 ), and their movement along the support/overlapping direction of the lid ( 8 ) on the flame spreader ( 4 ), to define an assembly ( 100 ) to be applied/removed on/from the injector holder ( 6 ) with a single movement. 
     
     
         3 . The gas burner according to  claim 1 , wherein the locking means between the lid ( 8 ) and the flame spreader ( 4 ) comprise fastening members ( 59 ) which support and/or define the magnetic connection means ( 70 ,  80 ) of the lid and/or flame spreader to the injector holder ( 6 ). 
     
     
         4 . The gas burner according to  claim 1 , wherein the locking means between the lid ( 8 ) and the flame spreader ( 4 ) comprise fastening members ( 59 ) which are independent and distinct from the magnetic connection means ( 70 ,  80 ) of the lid and/or flame spreader to the injector holder ( 6 ). 
     
     
         5 . The gas burner according to  claim 1 , wherein the flame spreader ( 4 ), alone or joined to the lid to define an assembly ( 100 ), rests on the injector holder ( 6 ) in correspondence with areas of mutual contact of said magnetic connection means ( 70 ,  80 ). 
     
     
         6 . The gas burner according to  claim 1 , wherein a body portion of the flame spreader ( 4 ), alone or joined to the lid to define an assembly ( 100 ), rests directly on a body portion of the injector holder ( 6 ). 
     
     
         7 . The gas burner according to  claim 1 , wherein the magnetic connection means comprise at least a first element ( 70 ) mounted or integrated on the injector holder ( 6 ) and at least a corresponding second element ( 80 ) which is mounted, or integrated, on the flame spreader ( 4 ) and/or on the lid ( 8 ), and which interacts magnetically with said at least one first element ( 70 ). 
     
     
         8 . The gas burner according to  claim 7 , wherein said at least one first element ( 70 ) is made, at least in part, in magnetized material, or is a magnet, while said at least one second element ( 80 ) is made at least in part in ferromagnetic material, or vice versa. 
     
     
         9 . The gas burner according to  claim 7 , wherein said at least one first element ( 70 ) is made at least in part in magnetized material, or is a magnet, while said at least one second element ( 80 ) is made at least in part in magnetized material, or a magnet, and in which said at least one first element ( 70 ) and said at least one second element ( 80 ) are arranged so that they face each other with poles of opposite sign which, therefore, attract each other. 
     
     
         10 . The gas burner according to  claim 1 , wherein the locking means between the lid and the flame spreader comprise at least one fastening member ( 59 ) which is associated with the lid ( 8 ) and which fits into at least one opening ( 54 ) obtained in the flame spreader ( 4 ). 
     
     
         11 . The gas burner according to  claim 10 , wherein said at least one fastening member ( 59 ) passes through said at least one opening ( 54 ) which is through, obtained in the flame spreader ( 4 ), to thus come out from a bottom portion of the flame spreader itself, and wherein said second element ( 80 ) of the magnetic connection means is defined at least in part by said at least one fastening member ( 59 ). 
     
     
         12 . The gas burner according to  claim 10 , wherein said at least one fastening member ( 59 ) passes through said at least one opening ( 54 ) which is through, obtained in the flame spreader ( 4 ), to thus come out from the bottom of the flame spreader itself, and wherein said second element ( 80 ) of the magnetic connection means comprises a nut ( 81 ), which engages on a portion of said at least one fastening member ( 59 ) which comes out from a bottom portion of the flame spreader ( 4 ). 
     
     
         13 . The gas burner according to  claim 1 , further comprising means for fastening the injector holder ( 6 ) to the plate of the cooking hob ( 10 ) and wherein said fastening means comprise said at least one first element ( 70 ) of the magnetic connection means which is configured to be mounted on the injector holder ( 6 ) so as to constrain the injection holder to the plate of the cooking hob ( 10 ). 
     
     
         14 . The gas burner according to  claim 1 , further comprising means for fastening the injector holder ( 6 ) to the plate of the cooking hob ( 10 ) which are distinct and separate with respect to said at least one first element ( 70 ) of the magnetic connection means which is mounted or integrated on the injector holder ( 6 ). 
     
     
         15 . The gas burner according to  claim 1 , wherein said flame spreader ( 4 ) is made: at least in part, at a bottom portion thereof, or entirely in ferromagnetic material.
