Plate burner

The innovation relates to a hob burner with a burner housing and at least one having numerous combustion channels Ceramic plate.

The innovation is based on the task of a hotplate burner of the aforementioned type to the effect that better utilization of the gas in the gaseous fuel-air mixture contained thermal energy is achieved.

This object is achieved, according to the present invention, that at a distance from the Abstrählürigsseite of Ceramic plate a radiation grille is arranged. In this way several very important ones emerge Advantages. Compared to previously known hotplate burners, the result is a smaller one Gas consumption, a shorter boiling-up time and a higher degree of efficiency of the hob burner. this is mainly based on the fact that the radiation grille part of the exhaust heat of the burned exhaust gases absorbs and in the form of thermal radiation again

Advantageous refinements of the hotplate burner emerge from the subclaims.

The hotplate burner according to the innovation is described in more detail below with the aid of the drawing, The drawing shows an exemplary embodiment of a hob burner partly in view, partly in Represents vertical section.

The hotplate burner has a burner housing i, at the upper open end of which there is at least one Ceramic plate 7 is attached, which has numerous combustion channels through which the from the burner housing 1 coming gaseous fuel-air mixture passes and on the Top side, the radiation side 14, of the ceramic plate burns. At a distance from the radiation ^ On the side 14 of the ceramic plate 7, a radiation grille 6 is arranged. This beam grating 6 is advantageous formed from expanded metal. This results in a particularly low manufacturing cost. The beam grating 6 is also advantageously designed to be slightly curved, see above that the distance 13 in the central area is selected to be greater than the distance 12 in the edge area. In this way, uniform heating and, accordingly, uniform heat radiation is achieved achieved and also the beam grating is insensitive to changing in this form Heating and cooling during operation and when the hob burner is not in operation.

A simple construction is thereby achieved * that the beam grating 6 is beveled at the edge ii after the edge of the ceramic plate 7, as in left part of the drawing is clearly visible. ϊη further development of this construction can then expediently the edge 11 of the beam grating 6 at least partially from a shape adapted Retaining ring 8 are included, the upper part of which is accordingly folded inward «By this retaining ring 8 is at the same time the beam filter 6 and the ceramic plate 7 on the burner housing 1 attached.

The retaining ring 8 is a sliding exhaust ring 3 surround, which is on the one hand on compression springs 2, which are distributed over the circumference a fastening plate 10 of the burner housing and, on the other hand, on a glass ceramic plate 5 supports. A seal 4 is advantageously located between the exhaust gas ring 3 and the glass ceramic plate 5 intended.

In the embodiment of the hob burner shown in the drawing, the jet grille is 6 designed circular. Accordingly, the ceramic plate 7 is circular for you in this case designed and the upper edge 15 of the burner housing and the retaining ring 8 and the exhaust ring are essentially circular. The reference numeral 9 is an abbreviated one Mixing tube provided, which is used to feed the fuel-air mixture into the interior of the burner housing 1 serves.
