  • Figure 1 illustrates a perspective view of the set of base and stove flame spreading cap under the present invention and parts thereof.
  • the present invention provides a most simplified structure for the burner base, which may be cleaned by the user in a more effective manner, as well as a combustion gas saving, as the heating process is benefited by a flame angle being more direc- ted to the container to be heated.
  • the flame presents a lower speed in the route of the pan, thereby resulting in a lower Nusselt number.
  • losses presented by the present invention are lower compared to the previous techniques, due to directioning of the jet obtained by the present solution, further contributing for the increased yield of the burner.
  • the set of base and stove burner spreading cap 1 comprises a base 200 which is able to support the cap 4 in a fitting cavity 5, as shown in Figures 3, 4 and 5 in more details.
  • the fitting profile herein proposed for the cap 4 is described in Figure 4, however other fitting forms and geometries can be used for conception of the present burner.
  • the cap 4 is a removable central part of the present invention.
  • Fitting cavity 5 is the region where the combustion gas flows to the subsequent ignition of the combustion air mixture.
  • the present invention counts on a simplified and efficient structure, when compared to previous techniques, in order to provide a more effective cleaning and an increased heating efficiency from the configuration proposed to the cap 4.
  • cap 4 is provided with primary gantries 15 and secondary gantries 25, both flame guiders located in the outmost periphery 300 of cap 4.
  • the present invention has primary gantries 15 formed in a smooth profile compared to conventional burners, usually manufactured with circu- lar and/or rectangular gantries, which make its cleaning difficult and cause accumulation of residues.
  • the user or final consumer, may easily clean the set of base and spreading cap 1 , according to the object herein proposed, with application of a single sponge, in view of the ease of access allowed by the developed product.
  • the primary gantries 15 are configured in a substantially concave shape and the secondary gantries 25 configured in a substantially convex shape.
  • cap 4 Other shapes offering the same facility of access to the set 1 may be used in the manufacture of cap 4.
  • These primary gantries 15 and secondary gantries 25 are further able to provide a continuous flame, the same being projected to reach a substantially high angle regarding the plan of base 200.
  • the present invention counts on a structure conceived for a better heat exchange with the container, or product to be heated with the set 1 , due to the shape of said primary gantries 15, thus providing, as already mentioned, a gas saving and an increased heating efficiency, thereby reducing food preparation time.
  • Figures 1 to 3, and particularly Figure 1 further illustrate the association of base 200 with a side portion 100.
  • Said side portion 100 is associated preferably with a side gas injection nozzle 2, as shown in figures 1 to 3.
  • the present invention can be developed with the gas input being directed to the bottom of the base 200, or further for several positions.
  • Figure 5 shows the union of lateral portion 100 with base 200.
  • This union, or coupling can be used for a wide range of fastening means.
  • This structure further allows manufacture of the base, according to the present invention, in a simplified manner, together with the manufacture of the stove table top, in such a way the table and the base will constitute a single piece.
  • the present invention provides a stove burner spreading cap provided with an optimized and innovative configuration in face of products commercially available nowadays.
  • the cap 4 is substantially circular, the same being provided with a more external periphery 300 configured in radially projected primary gantries 15 and secondary gantries 25.
  • primary gantries 15 are configured in a substantially concave shape, in order to meet requirements of better heating and burner cleaning, the secondary gantries 25 being configured in a substantially convex shape.
  • said cap 4 is constructed in a substantially smooth shape.
