    Figure 1 shows in schematic side view an embodiment of a gas burner 1 for a domestic cooking appliance. The household cooking appliance can be, for example, a gas cooker or a gas cooking range. The gas burner 1 comprises a lower part of the burner 2, which may be fixed to a cooking field plate of the domestic cooking apparatus and is made, for example, of an aluminum or magnesium material, which may in particular be a die-cast aluminum component.
    The gas burner 1 further comprises an ignition element 3 to ignite a fuel / air gas mixture, as well as a thermal element 4 to control the flame. The thermal element 4 is connected to a gas shut-off valve of the gas burner 1 such that, when the flame of the gas burner 1 goes out, the gas shut-off valve interrupts the gas supply current directed towards the burner of gas 1. The ignition element 3 and the thermal element 4 can be housed in housing sections 5, 6 of the lower part of the burner 2.
    In addition, the gas burner 1 comprises a burner lid 7, which is supported on the lower part of burner 2 and can be removed from the lower part of burner 2 being raised. The burner cover 7 has first gas distribution channels 8, which are provided in a gas distribution section 9 of the burner cover 7. The burner cover 7 can be made of an aluminum or iron material. The gas distribution section 9 rests on an upper edge 10 of the lower burner part 2. The gas outlet openings 11 of the gas burner 1 are


    defined by the first gas distribution channels 8 and by the upper edge 10 of the lower part of burner 2.
    Figure 2 shows an embodiment of a burner cover 7 in top view, Figure 3 shows the burner cover 7 according to Figure 2 in perspective view, Figure 4 shows the burner cover 7 according to Figure 2 in side view, figure 5 shows an enlarged section view of the burner lid 7 according to figure 4, figure 6 shows a schematic section view of the burner lid 7 according to figure 2, and figure 7 shows a view of enlarged section of the burner cover 7 according to figure 6. Next, reference is made simultaneously to figures 2 to 7.
    The burner lid 7 has a discoidal base section 12, which preferably has a circular geometry. The annular gas distribution section 9 is connected to the base section 12, and surrounds a central disc section 13 of the base section 12. An annular outer section 14 of the base section 12 is provided surrounding the outside of the gas distribution section 9. In the outer section 14, blind hole perforations 15 may be provided. As shown in Figure 2, four blind hole perforations 15 that are arranged in pairs opposite each other can be provided. The outer section 14 and the gas distribution section 9 are concentrically arranged relative to each other.
    The gas distribution section 9 comprises the first gas distribution channels 8, the quantity of which may be as desired. As shown in Figures 2 and 3, twenty-four first gas distribution channels 8 may be provided. The first gas distribution channels 8 extend radially from an inner surface 16 (Figure 3) of the gas distribution section 9 in the direction of a circulating outer edge 17 of the base section 12. Specifically, the first gas distribution channels 8 extend in the direction of the outer section 14 of the base section 12. The burner cover 7 has an axis central or symmetry 18. Each first gas distribution channel 8 extends completely through the gas distribution section 9.
    As shown in Figure 5, each first gas distribution channel 8 has a cross section with a "T" shaped geometry, which is open in the direction opposite to the base section 12. Specifically, the first gas distribution channel 8 is open in the direction of the upper edge 10 of the lower part of burner 2; that is, the first gas distribution channel 8 is closed by the upper edge 10 of the lower part of the burner 2 forming a gas outlet opening 11 in the form of a "T" (figure 1). As also shown in Figure 5, the “T” shaped geometry of the cross section

    perimeter u9 of the gas distribution section 9. Every two second gas distribution channels 23 are positioned opposite each other.
    As Figure 2 shows, a second gas distribution channel 23 may be arranged rotated at an angle α with respect to a first horizontally distributed gas distribution channel 8. The angle α can rise, for example, to 22.5 °. As Figure 5 shows, each second gas distribution channel 23 is disposed between two first gas distribution channels 8. Preferably, the side walls 24, 25 of two first gas distribution channels 8, directed towards the second gas distribution channel 23, are rounded.
    As Figure 7 shows, the inlet surface 26 of each second gas distribution channel 23 is inclined at an angle β with respect to the inner surface 16 of the gas distribution section 9. In this way, the mixture combustible gas / air can flow better into the second gas distribution channels 23. The angle β can rise, for example, to 20 °, and the depth t of the second gas distribution channel 23 amounts, for example, to 0 , 5 mm.
    As shown, for example, in figure 6, the burner cover 7 also has positioning elements 27 for positioning the burner cover 7 on the lower burner part 2 of the gas burner 1. The positioning elements 27 extend from the gas distribution section 9 in the opposite direction to the base section 12. The upper side 28 of the gas distribution section 9 is inclined in the direction of the outer edge 17 of the base section 12. The distribution channels of gas 8, 23 are positioned parallel to the upper side 28 and, from the central section 13, extend obliquely in the direction of the outer section 14.
    The positioning elements 27 are arranged on the inclined upper side 28, which are cuneiform and inclined in the direction of the outer edge 17 of the base section 12. The burner cover 7 can be centered next to the lower part of the burner 2 thanks to the cuneiform geometry of the positioning elements 27. In the lower part of the burner 2, housing sections are preferably provided to accommodate the positioning elements 27. The positioning elements 27 are arranged evenly distributed along the perimeter u9 of the gas distribution section 9, and are positioned in pairs opposite each other. As shown in Figures 2 and 3, the positioning elements 27 are preferably arranged on wings 22 of the gas distribution section 9 which are arranged adjacent to a wing 22 with a second gas distribution channel 23.


    The burner cover 7, or the base section 12 of the burner, has an outer diameter d7 (Figure 2). By means of the first gas distribution channels 8 and the gas distribution section 9, a fuel gas introduced in a metered manner into a mixing space provided between the burner lid 7 and the lower burner part 2 is uniformly mixed with primary and uniformly distributed air along the perimeter u9 of the gas distribution section 9. The first gas distribution channels 8 here define the volumetric flow of the gas for normal use of the gas burner 1, achieving a burner flame particularly stable thanks to the "T" shaped geometry of the cross section of the first gas distribution channels 8. Furthermore, the "T" shaped geometry of the first gas distribution channels 8 makes it possible for the mixture Air / gas fuel comes out with particular uniformity.
    The second gas distribution channels 23, of which one is disposed directly next to the ignition element 3, improve ionization during inflammation and enable safe and rapid ignition even at elevated temperatures, low pressure, and being dirty the burner cover 7. Thanks to the reduced geometry of the cross section of the second gas distribution channels 23, the gas leaves these more rapidly.
    The burner cover 7 is positionable in the correct position relative to the lower part of the burner 2 by means of the positioning elements 27. In this way, a second gas distribution channel 23 is positionable next to an ignition element 3. When modified the geometry of the cross section of the gas distribution channels 8, 23, the height of the burner cap 7 can be reduced and, thus, the height of the gas burner 1, while increasing the efficiency of the burner of gas 1, and in addition, the height of the container support can be reduced by making a gas hob with a lower height. An optimized angle of the burner flame can be achieved by extending the gas distribution channels 8, 23 obliquely in the direction of the outer edge 17 of the base section 12 starting from the inner surface 16 of the gas distribution section
    9. The partial shutdown of the burner flame is avoided in order to keep carbon monoxide emissions low.
    Figure 8 shows in schematic side view another embodiment of a gas burner 1, Figure 9 shows in schematic top view an embodiment of a burner lid 7 for the gas burner 1 according to Figure 8, Figure 10 shows the burner cap 7 in perspective view, and Figure 11 shows the burner cap 7


    in view of schematic section. Next, reference is made simultaneously to Figures 8 to 11.
    The gas burner 1 has a lower part of burner 2 and a burner cover 7. The gas burner 1 according to figure 8 differs from the gas burner 1 according to figure 1 in that it has a higher nominal power. The burner lid 7 has a diameter d7 larger than the burner lid 7 according to Figure 2, and the amount of first gas distribution channels 8 can correspond here to the amount of first gas distribution channels 8 of the lid of burner 7 according to figure 2. In figures 9 to 11, second gas distribution channels 23 are not shown.
    Figure 12 shows in schematic side view another embodiment of a gas burner 1, Figure 13 shows in schematic top view an embodiment of a burner lid 7 for the gas burner 1 according to Figure 12, Figure 14 shows the burner cover 7 in perspective view, and Figure 15 shows the burner cover 7 in schematic section view. Next, reference is made simultaneously to Figures 12 to 15.
    The gas burner 1 according to figure 12 differs from the gas burner 1 according to figure 8 in that it has a higher nominal power. The gas burner 1 has a lower burner part 2 and a burner cover 7. The diameter d7 of the burner cover 7 according to figure 13 is here larger than the diameter d7 of the burner cover 7 according to figure 9, and the burner cover 7 according to figure 13 has a larger number of first gas distribution channels 8. Furthermore, the burner cover 7 differs from the burner cover 7 according to figure 2 in that the positioning elements 27 do not They are cuneiform, but are made in the shape of a truncated cone.
    Thanks to the positioning of the burner cover 7 with respect to the lower part of burner 2 by means of the positioning elements 27, the relative position of the ignition element 3 with respect to a second gas distribution channel 23 is precisely defined, with which improves the ignition. The height of the burner lid 7 can be reduced through the new "T" shaped geometry of the first gas distribution channels 8. Thus, the gas burner 1 can be dimensioned more flatly with the same or greater efficiency, and the gas burner 1 can be easily covered with a container or grill support. Therefore, the geometry of the gas distribution channels 8, 23 makes it possible to reduce the height of the gas burner 1 while improving efficiency. By running the gas distribution channels 8, 23 obliquely upward in the direction of the outer section 14 of the base section 12, it is possible to


    getting a better burner flame angle, which also improves the efficiency of the gas burner 1. Together with the reduction in the height of the gas burner 1, the diameter d7 of the burner cap 7 can be increased and, thanks at the larger diameter d7, both the distribution of the flame and its stability are improved.
