DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS OF THE PRESENT INVENTION

(8) The gas burner 1 has a gas inlet opening 2, which leads into a gas input chamber 3. The gas input chamber 3 rises at least partially by means of an angled base wall 4 into a gas chamber 5 disposed above the gas input chamber 3. The gas chamber 5 has a disk-shaped base form. An inner burner 6 and the receiving region 7 for a thermocouple and spark ignition are integrated in the gas chamber 5. The gas chamber 5 opens at the top in the form of an arched gas flue 8. A burner ring (not shown) can be positioned on the gas flue 8, to enclose an inner burner chamber with the inner burner 6, a main flame being produced at its outer periphery.

(9) The gas chamber 5 can have a variable height h. It is flat compared with the prior art, in other words its maximum diameter D is greater than its maximum height h.

(10) The gas chamber 5 has an upward curving centric partial gas chamber 5a above the gas input chamber 3.

(11) Gas flowing into the gas input chamber 3 from the gas inlet opening 2 is routed into the gas chamber 5 by the angled surface 4 without significant pressure loss. The gas flow from the gas flues 8 is essentially regularly distributed here, as the inner burner wall 6a starts in the upper region of the angled base wall 4 and the through openings 10, receiving region 7 and centric partial gas chamber 5a are disposed there so that the gas flow is distributed in the remainder of the gas chamber 5 without major pressure loss and can flow out of the gas flues 8. This manner of deflection reduces the pressure loss in the gas flow, resulting in a greater throughflow speed of the gas flow and thus more effective primary air intake, in turn resulting in better combustion characteristics, see also FIGS. 1, 3, 4, 6.

(12) FIG. 2 shows the gas burner 1 from FIG. 1 from below with the gas inlet opening 2 for the main flame or the outer circuit, the angled base wall 4 of the gas input chamber and a further gas connection 9 to supply the inner burner and through holes 10 for guiding the spark ignition and thermocouple. The angled base wall 4 and therefore the gas input chamber 3 widen at least partially in a lateral manner from the gas inlet opening 2 to the gas chamber.

(13) FIG. 3 shows a plan view of the gas burner 1 from FIG. 1 along a section line A-A from FIG. 1. As in FIG. 2, the angled base wall 4 and therefore the gas input chamber 3 widen from the gas inlet opening 2 to the gas chamber 5. The gas chamber 5 has a disk-shaped base form and only deviates from this at projections 11 in the side wall 12 to circumvent screw holes 13. The receiving region 7 for the thermocouple and spark ignition has corresponding through holes 10 and is configured as a single piece with the inner burner 6.

(14) FIG. 4 shows a sectional diagram of a side view as in FIG. 1 along the section line B-B from FIG. 3. This view shows one of the through holes 10 in the receiving region 7 for the spark ignition and/or thermocouple.

(15) FIG. 5 shows a sectional diagram of a side view as in FIG. 1 along the section line C-C from FIG. 3, in which the disk shape of the gas chamber 5 can clearly be seen.

(16) FIG. 6 shows a plan view of the gas burner from FIG. 1 along a section line D-D from FIG. 1 with the three gas flues 8, the centrically disposed inner burner 6 and the through holes 10 for the spark ignition and/or thermocouple.

(17) The invention is not restricted to the illustrated exemplary embodiment. Flow baffles can thus be used, for example where there are deviations from the laterally centric arrangement of the gas inlet opening. The gas input chamber can also be formed differently, in particular the angled base wall and/or the form of the lateral widening. The thermocouple and spark ignition can also be guided outside the gas chamber.
