Energy saving jet burner

Abstract

A burner for a gas stove includes an outer shell having a first longitudinal end and a second longitudinal end and an inlet conduit arranged inside the outer shell and defining an inlet port at the first longitudinal end to facilitate an entry of an air and a gas inside the inlet conduit. An inner shell is arranged between the inlet conduit and the outer shell and defines a first outlet channel between the inlet conduit and inner shell and a second outlet channel between the inner shell and the outer shell. A flow plate is coupled to the inlet conduit and includes a plurality of guide blades defining a plurality of passages therebetween. Each blade includes a flat portion and a guide portion extending obliquely and downwardly from the flat portion to facilitate a swirling of an air gas mixture exiting the passages.

         2 . The burner of  claim 1  further including a cover plate attached to an end of the inner shell and arranged at a distance from the flow plate defining an intake chamber therebetween to receive an air gas mixture from the inlet conduit, wherein the air gas mixture flows to the first outlet channel from the inlet chamber through the plurality of passages. 
     
     
         3 . The burner of  claim 2 , wherein the cover plate includes
 a bottom arranged substantially parallel to the flow plate and arranged proximate to the flow plate,   a sidewall portion extending from the bottom around a central axis of the cover plate, and   a flange portion extending radially outwardly from the sidewall portion, wherein the sidewall portion includes a substantially truncated cone shape.   
     
     
         4 . The burner of  claim 2  further including a vane assembly arranged coaxially and inside the outer shell and extending from the cover plate to the second longitudinal end of the outer shell, the vane assembly includes a plurality of guide vanes arranged circularly around a central axis and defining a plurality of radially extending outlet passages therebetween to allow a flow of air gas mixture from the second outlet channel to an inside of the vane assembly. 
     
     
         5 . The burner of  claim 4 , wherein an outer end of the vane assembly is arranged at a distance from the outer shell defining a gap therebetween. 
     
     
         6 . The burner of  claim 4 , wherein the outer shell includes
 a base arranged at the first longitudinal end and attached to the inlet conduit,   a sidewall extending from the base and arranged circularly around a central axis, and   a top plate arranged at the second longitudinal end and extending radially inwardly from the sidewall, wherein the top plate covers an upper end of the guide vanes.   
     
     
         7 . The burner of  claim 6 , wherein the base defines an opening arranged coaxially to the inlet port of the inlet conduit. 
     
     
         8 . The burner of  claim 1 , wherein the flow plate includes a central opening arranged coaxially to an outlet port of the inlet conduit. 
     
     
         9 . The burner of  claim 1 , wherein the inlet conduit includes a convergent portion disposed proximate to the outlet port to increase a velocity of air gas mixture exiting the inlet conduit. 
     
     
         10 . A burner for a gas stove, the burner comprising:
 an outer shell having a first longitudinal end and a second longitudinal end;   an inlet conduit arranged coaxially and inside the outer shell and extending from the first longitudinal end towards the second longitudinal end and defining an inlet port at the first longitudinal end to facilitate an entry of an air and a gas inside the inlet conduit;   an inner shell arranged coaxially to the outer shell and the inlet conduit and arranged between the inlet conduit and the outer shell, wherein a first outlet channel is defined between the inlet conduit and inner shell and a second outlet channel is defined between the inner shell and the outer shell, the inner shell defines at least one opening arranged proximate to the first longitudinal end to facilitate a flow of an air gas mixture from the first outlet channel to the second outlet channel;   a flow plate coupled to the inlet conduit and including a plurality of guide blades arrayed circularly around a central axis and defining a plurality of passages therebetween, each blade extends radially outwardly from the inlet conduit to the inner shell and includes a flat portion and a guide portion extending obliquely and downwardly towards the first longitudinal end from the flat portion to facilitate a swirling of an air gas mixture exiting the passages;   a cover plate attached to an end of the inner shell and arranged at a distance from the flow plate defining an intake chamber therebetween to receive an air gas mixture from the inlet conduit, wherein the air gas mixture flows to the first outlet channel from the inlet chamber through the plurality of passages; and   a vane assembly arranged coaxially and inside the outer shell and extending from the cover plate to the second longitudinal end of the outer shell, the vane assembly includes a plurality of guide vanes arranged circularly around a central axis and defining a plurality of radially extending outlet passages therebetween to allow a flow of air gas mixture from the second outlet channel to an inside of the vane assembly.   
     
     
         11 . The burner of  claim 10 , wherein the cover plate includes
 a bottom arranged substantially parallel to the flow plate and arranged proximate to the flow plate,   a sidewall portion extending from the bottom around a central axis of the cover plate, and   a flange portion extending radially outwardly from the sidewall portion, wherein the sidewall portion includes a substantially truncated cone shape.   
     
     
         12 . The burner of  claim 10 , wherein an outer end of the vane assembly is arranged at a distance from the outer shell defining a gap therebetween.
