Abstract
The invention relates to a gas burner comprising a burner head and burner cap as well as a rotatable injector which is assigned to the burner head and presents a vertical nozzle housing and a gas connection. The aim of the invention is to create a burner for domestic and industrial use which can be adjusted to a very wide range of output settings. To this end the burner head (4) is provided with a recess for an additional simmer burner (14) which is positioned mainly on the outer edge of the burner head, and a wall element (5a) which is assigned to said area and forms a half-chamber is mounted on the cap (5).
Description
Gas Burner with Simmer Burner The present invention relates to a gas burner comprising a burner head and burner cap as well as a rotatable injector that is associated with the burner head and incorporates a vertical nozzle housing and a gas connection.
The most varied configurations of gas burners are known, for example from EP-0 859 191 A2 or EP-0 611 920 A1, DE-31 23 751 C2, GB-2 272 283-A, US-5 160 256, or AT-387 647-B, to quote but a few examples. In these, a gas burner comprises a burner cap on a burner head, to which, as a rule, in the examples cited above, injectors with the nozzle housing are connected to a gas line, there being solutions in which the injector is arranged on the burner head so as to be able to rotate, e.g., by means of a fine thread, in order to permit adjustment of the distance from the full-flame nozzle relative to the central burner head or to permit alteration of the angle of the gas line connection.
Common to most of these burners is the fact they have an igniter on the outside edge, which is associated with the gas mixture outlet openings, and a thermocouple, the former being used to ignite the gas/air mixture, the latter being used to monitor the presence of a flame.
One problem that is encountered, in particular, in the case of high-output gas burners, is the fact that their output cannot be reduced to the point that such burners can perform a purely warming function; this is perceived as a considerable disadvantage when such burners are used in commercial kitchens.
It is the objective of the present invention to create a gas burner for household and commercial use.that can be regulated over a very wide range of output settings.
This objective has been achieved with a gas burner of the type described in the introduction hereto, in that there is a recess for an additional simmer burner that is positioned mainly on the outer edge of.the burner head, and a wall element, which is associated with said area and forms a main chamber, which is mounted on the cap.
Because of this configuration of the burner it is possible to operate burners of this kind in a range that varies from < 0.15 kilowatt to 5.0 kilowatt, for example, since a simmer burner of this kind, which requires relatively little energy, is used as a type of standby arrangement, and can thus fulfill some additional energy-supply functions that are not possible using a large burner alone.
In this connection, it is expedient to associate a thermocouple and an igniter with the simmer burner, as is also foreseen by the present invention. If the burner is turned on, initially, the simmer burner is ignited, after which the main burner can be turned on using the full flame nozzle, if this is required.
In an advantageous further configuration, provision is made such that the burner is formed as a single-ring burner with a break in the area of the additional simmer burner.
Thus, for example, the single ring burner with its gas feeder channels can extend through a range of 340°, with the remaining 20° being taken up by the area of the simmer burner.
In one version of the present invention, the housing for the simmer burner, the igniter, and/or the thermocouple can be formed as an integral component of the burner head; in another, alternative configuration, this housing can be in the form of a separate element that can be attached to the burner head.
The most varied configurations of gas burners are known, for example from EP-0 859 191 A2 or EP-0 611 920 A1, DE-31 23 751 C2, GB-2 272 283-A, US-5 160 256, or AT-387 647-B, to quote but a few examples. In these, a gas burner comprises a burner cap on a burner head, to which, as a rule, in the examples cited above, injectors with the nozzle housing are connected to a gas line, there being solutions in which the injector is arranged on the burner head so as to be able to rotate, e.g., by means of a fine thread, in order to permit adjustment of the distance from the full-flame nozzle relative to the central burner head or to permit alteration of the angle of the gas line connection.

A further configuration of the present invention is such that the cross section for the gas outlet opening of the simmer burner is formed by slits that are arranged horizontally one above the other and/or vertically adjacent to each other, when, in a further configuration, provision can be made such that the thermocouple and the igniter are arranged in front of the slots in the simmer burner.
The simmer burner can be fitted with a lock washer, when provision can be made such that the simmer burner and/or the burner head are attached to each other or secured to the stove-top pan or the stove top plate by spring elements.
Once the burner cap or the simmer burner have been removed, the full-flame burner and the simmer burner nozzle can be replaced from above, using a socket wrench, for which the present invention also makes provision.
Additional details, advantages, and features of the present invention are set out in the description that follows, and in the drawings appended hereto. These drawings show the following:

Additional details, advantages, and features of the present invention are set out in the description that follows, and in the drawings appended hereto. These drawings show the following:
Figure 1: A cross section through the burner according to the present invention, showing the stove top;
Figure 2: A side view in the direction indicated by the arrow II
in Figure 1;
Figure 3: A plan view as indicated by the arrow III in Figure 2, showing the burner cap partially cut away in the area of the simmer burner.
The gas burner, numbered 1 in toto, has a burner head 4 that rests on a stove top plate 2 and passes through a corresponding opening 3 in the stove top plate 2; this burner head 4 is fitted with a burner cap 5. An injector tube 6 is located centrally in the burner head 4 and is secured in place within the burner head 4 by means of spring catches 7.
On its underside, the injector tube 6 incorporates an external thread 8 that screws into a nozzle housing 9; this nozzle housing 9 supports a full-flame nozzle 10. The distance between the full-flame nozzle and the injector 6 can be varied by way of the thread 8. The primary gas supply line is numbered 11.
On one side, the burner head 4 has an additional bore 12 on its outer edge, and a supporting element 13 is fitted into this.
This supporting element 13 has an additional simmer burner 14, an igniter 15, and a thermocouple 16.
A simmer burner nozzle 17 and a secondary gas supply line 18 are associated with the additional simmer burner 17, the simmer burner 14 with the nozzle 17, the igniter 15, and the thermocouple 16 once again being secured directly on the carrier 13 through a spring element 19 and thus indirectly to the burner head 4.
,, As can be seen., in particular, in Figure 2, the burner cap 5 ins corporates a partition wall 5a that encloses the simmer burner 14 on one side and extends vertically downward; this partition wall 5a separates this area from the other internal gas space 20 within the burner, so that the gas outlet channels 21 do not enclose the full circle of the burner cap, but leave a small area free, as can be seen in Figure 2.
In the example shown, the gas outlets of the simmer burner are in the form of transverse slits 22; they could also be in the form of longitudinal slits or bores. This will not be discussed in detail herein.
Spacer pins 23 can be used in order to secure the burner head 4 to the particular part of the stove, which is numbered 2; these are screwed into the burner head 4 from below and are fixed to the underside of the stove top plate 2 through spring elements 24. In addition, Figure 2 also illustrates the possibility of using a lock washer -~
It is, of course, self-evident that the embodiment of the present invention described herein can be modified without prejudice to its underlying concept. For example, as has been stated heretofore, the present invention is not restricted to specific types of gas channels 21 or 22; in place of the single-ring burners described herein, it is possible to other burner forms, such as multi-ring burners.
