Abstract

The invention relates to a two circuit burner comprising a burner body and a central burner and a second burner ring which surrounds the central burner at a distance. An igniting device and the thermostat element are associated with the central burner. The aim of the invention is to improve the gas supply, the burner qualities and control ability and adjustability thereof at a low production cost. To achieve this, the burner body (2) is embodied in such a way that it can be placed on a vitroceramique plate (6) or fixed onto a steel trough (6'). The burner body (2) comprises a centric receiving element (4) for the central burner (17) and is equipped with gas flues (8) distributed on the perimeter, covered by an intermediate ring (15) when the air passage openings (16) in the inner area of the burner (1) are left open. The burner ring (19) of the external burner is mounted on the intermediate ring (15).

Description

"Dual-circuit burner with Brennerrinσ and middle burner"

The invention is directed to a two-circuit burner with a burner body and with a central middle burner and a surrounding spaced second burner ring, where the center of the burner is associated with the spark plug and thermocouple.

Such a two circuit burner is known for example from DE-41 25 308 or by the designed by the Applicant in 1986 burner. In the latter construction, for example, a compact ring burner with lateral assigned in a gas annulus leading gas supply whose ring burner was held with the support body at a distance to the trough plate, a centric middle burner equipped with the spark plug and thermocouple was. A comparable construction is also called the DE-41 25 308 and the corresponding EP-0525299.

The aim of the present invention is in particular to further develop the design from their own home and improve in terms of gas supply, the burner qualities and controllability while economic production.

In a dual-circuit burner of the type described at the outset this object is achieved according to the invention in that the burner body is constructed for resting on a glass ceramic plate, or for fixing to a trough plate, wherein the torch body has a central receptacle for the middle burner and distributed over the circumference of the gas passage fireplaces is provided, the cavities of an intermediate ring, leaving free of air passages in the interior of the burner are covered, being mounted on the intermediate ring of the burner ring of the external burner.

This design results in a very compact dual-circuit burner to glass ceramic plates as the troughs of herds as fixable od burners. Like. By forming gas passage fireplaces which leave between them passages for the ambient air, it is possible to supply the centric middle burner sufficient air at the same time is a simple production, either as a cast or be it as a forged part, possible.

Further embodiments of the invention emerge from the subclaims.

Referring referred to Fig. 1 and 17 is in connection with FIG. 2, the torch illustrated therein, generally designated 1, of a torch body 2 which is formed in two parts in the illustrated example, namely from a burner lower part 3 with a central cam 4 and a burner top part 5, which are mounted with the interposition of a glass ceramic plate 6 and support seals 7 at a corresponding hotplate.

As is also apparent from Fig. 3, inter alia, comprises the burner top distributed on the circumference three gas passage fireplaces 8 which have a circular extension of approximately 40 °, leaving the corresponding areas of the same size to the interior of the burner, the through-holes 9 of the gas passage fireplaces 8 in a inner circular Gasverteilringraum 10 open, in the horizontally and eccentrically with a gas supply tube 11 opens with venturi injector 12 and Vollbranddüse 13, wherein the torch angle with these elements in Fig. 3 is designated by 14.

As, for example, among other things, is clear from Fig. 1, the bottom profile of the Gasverteilringkanales dashed there drawn, increasing designed from the lowest point in the region of the gas supply pipe 11 to the opposite side about 180 ° so as to provide an optimal gas distribution. Recognizable arise in placing the intermediate ring denoted by 15 on the burner top 5, three air passage holes 16 for the middle burner, generally designated 17.

The intermediate ring has an upper annular groove 18 while the corresponding therewith, also comprises from top patch burner ring 19 to the burner bores 20, a corresponding Kreisringnut 21, cross-sectionally approximately designed trapezoidal, wherein the gas passage holes emanating 20 from the acute angle extending region of this annular groove 21st

Toggle for positioning of all elements or one another in the correct assignment is on the burner upper part 5 a upwardly facing fixing lug, in Fig. 2 with 22 denotes provided, wherein both the intermediate ring 15 as corresponding to the burner ring 19 from above downwardly extending grooves 23 and 24 are provided.

In FIG. 1 is also shown that the burner base 3 distributed on the periphery recordings, generally designated 25, having for springs 26, which serve to support on the underside of the glass ceramic plate 6.

In Fig. 1, the designated gas supply 27 for the central burner 17 and the associated nozzle 28 is located, while the positioning of a thermocouple 29 and a spark plug 30 in Fig. Is merely indicated in a plan view. 3

Insofar as the same components, in particular functionally identical components are shown in the other figures, carry the same reference numerals, even if they are designed slightly differently.

In Fig. 17 is somewhat more clearly in section generally designated 17 middle burner shown with its injector 32 and a central burner, designated by 34, and the burner bores 35 in Mittenbrennerdek- kel 36, wherein the gas supply of the middle burner is indicated at 37. List of reference numerals
