DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE PRESENT INVENTION

(9) Identical elements or those of identical function are shown with the same reference characters in the figures, unless otherwise stated.

(10) FIG. 1 shows a schematic perspective view of a gas burner 31. The gas burner 31 has a base segment or burner pan 1. An upper part (not shown in the figures) of the gas burner 31 can be arranged in or on the burner pan 1.

(11) As shown in FIG. 4, the burner pan 1 has a pan-type burner receiving segment 3 for receiving the upper part of the gas burner 31 and a nozzle receiving segment 4, preferably arranged in the center of the burner receiving segment 3, for receiving a gas injector nozzle of the gas burner 31. The burner pan 1 also has a gas connector 5 arranged at the side of the burner receiving segment 3. The gas connector 5 is connected fluidically to the nozzle receiving segment 4 by way of a gas duct 6.

(12) The burner pan 1 also has a contact surface 7, which is designed to come into surface contact with a cooktop plate 8 of the cooktop 2. In particular the contact surface 7 is designed to come into surface contact with the lower face of the cooktop plate 8. The contact surface 7 runs round the edge of the burner receiving segment 3 preferably in the manner of a ring. In the top view the burner receiving segment 3 has a circular shape with two lateral flat portions 9, 10 arranged parallel to one another. The contact surface 7 has wing-type fastening segments 11, 12 in the region of said flat portions 9, 10. The burner pan 1 can be fastened to the cooktop plate 8 with the aid of the fastening segments 11, 12. A fastening hole 13, 14 is preferably provided on each of the fastening segments 11, 12. The fastening holes 13, 14 can be embodied as threaded holes.

(13) The burner pan 1 also comprises a holding device 15 for holding a thermal element 16. The thermal element 16 is designed to detect the operating state of the gas burner 31. The holding device 15 and contact surface 7 are preferably configured from a single piece of material. The holding device 15 has a thermal element receiving slot 17 positioned perpendicular to the contact surface 7. In particular side flanks 32, 33 of the thermal element receiving slot 17 are positioned perpendicular to the contact surface 7. The thermal element 16 can be pushed into the thermal element receiving slot 17 laterally and in particular parallel to the contact surface 7. Perpendicular here means an angle of 9010, more preferably 905, more preferably 901, more preferably precisely 90.

(14) As shown in FIG. 4, a housing 18 of the thermal element 16 can engage with a form fit behind the thermal element receiving slot 17 so that the thermal element 16 can be fixed perpendicular to the contact surface 7. In particular the thermal element 16 can be fixed in the z direction of the burner pan 1. The holding device 15 is preferably plate-shaped. FIG. 4 shows a coordinates system indicating an x, y and z direction of the gas burner 31 or the burner pan 1. The housing 18 of the thermal element 16 is preferably configured in the manner of a pin with two flanges 19, 20 arranged at a distance from one another and running round the edge of the housing 18 in the manner of a ring. The thermal element receiving slot 17 has an engagement segment 21, which engages between the flanges 19, 20. The thermal element receiving slot 17 therefore has the shape of an H on its side in the orientation in FIG. 4.

(15) The holding device 15 is also additionally designed to hold an ignition element 22 of the gas burner 31. To this end the holding device 15 preferably has an ignition element receiving slot 23 positioned perpendicular to the contact surface 7. In particular side flanks 34, 35 of the ignition element receiving slot 23 are positioned perpendicular to the contact surface 7. A housing 24 of the ignition element 22 can engage with a form fit behind the ignition element receiving slot 23 so that the ignition element 22 is fixed perpendicular to the contact surface 7 and in particular in the z direction of the burner pan 1. The housing 24 of the ignition element 22 is preferably configured in the same way as the housing 18 of the thermal element 16.

(16) The thermal element receiving slot 17 and the ignition element receiving slot 23 are preferably arranged in such a manner that they run toward one another. In particular a center line 25 of the thermal element receiving slot 23 is arranged in such a manner that it intersects a center line 26 of the ignition element receiving slot 23. The thermal element receiving slot 17 and the ignition element receiving slot 23 are preferably arranged at a predefined angle to one another. In other words the center lines 25, 26 intersect at the angle . The predefined angle is preferably 90 to 120, more preferably 95 to 115, more preferably 100 to 110.

(17) FIG. 2 shows the thermal element 16 being pushed in in a first mounting direction M.sub.1 and the ignition element 22 being pushed into the ignition element receiving slot 23 in a second mounting direction M.sub.2. The mounting directions M.sub.1 and M.sub.2 are oriented along the center lines 25 and 26.

(18) FIG. 3 shows the thermal element 16 mounted on the gas burner 31 or on the burner pan 1 and the ignition element 22 mounted on the gas burner 31 or the burner pan 1. The gas burner 31, the thermal element 16 and the ignition element 22 can form a gas burner arrangement 30.

(19) The gas burner 31 can be screwed in particular to a fastening ring 27 that can be positioned on the cooktop plate 8. FIG. 6 shows the mounting of the gas burner 31 with the thermal element 16 and the ignition element 22 from a lower face of the cooktop plate 8 in a mounting direction M.sub.3. The fastening ring 27 is arranged on the upper face of the cooktop plate 8.

(20) FIG. 7 shows the already mounted cooktop 2. The fastening ring 27 here is screwed to the burner pan 1 with the aid of the latter's fastening holes 13, 14. As shown in FIG. 5, the fastening ring 27 has a recess 28 for the thermal element 16 and a recess 29 for the ignition element 22. When the burner pan 1 is mounted on the cooktop plate 8, the thermal element 16 and the ignition element 22 are pushed through the corresponding recesses 28, 29 and are thus fixed in the x and y directions of the burner pan 1.

(21) The gas burner arrangement 30 has the gas burner 31 with the burner pan 1 and at least the thermal element 16, which is pushed laterally into the thermal element receiving slot 17. The gas burner arrangement 30 can also have the ignition element 22, which is pushed laterally into the ignition element receiving slot 23 of the holding device 15. The cooktop 2 can also have the fastening ring 27 in addition to the cooktop plate 8, the gas burner 31 and the burner pan 1.

(22) The present invention can be modified in many ways despite being described with reference to exemplary embodiments.
