Description

GERMAN

The invention relates to a radiation grill device for the hotplates of gas-fired cooking appliances, in particular stoves, their hob burners with a burner head and one on this detachably arranged burner head cover are equipped and which thereby optionally for Radiant grills can be used that a radiant grill burner at a distance above the cooking burner is arranged, which illuminates the material from above. Under radiation grilling will thereby understood a preparation process of meat dishes in particular, in which the food is not on a heated and grease-covered surface essentially through heat conduction, but through Radiation, preferably infrared radiation, can be prepared.

In the known devices of this type, the radiant grill burner is in fixed parts of the device pivoted and therefore requires its own fuel supply line and its own connection and adjusting devices.

Apart from the considerable construction costs that this entails, such grilling devices permit not readily, existing gas stoves already in households or the like on food preparation to convert by grilling with radiation.

The invention has set itself the task of eliminating these deficiencies and accordingly a grill device to be trained so that they can be used in a simple manner, especially with existing gas stoves or Gas stoves can be installed and removed again without significant assembly work.

This task is in the gas-fired cooking appliances mentioned at the outset, in particular stoves, their Hotplate burner with a burner head and a burner head cover detachably arranged on this are equipped, solved in that the radiant grill burner with a hollow Foot is provided, which can be placed gas-tight on the burner head instead of the burner head cover and which via a gas pipe, which also acts as a connecting part between the radiant grill burner and his foot acts, directs the fuel from the burner head into the grill burner, wherein the connecting part is cranked so that it is the placement of a grill food support on the pan support elements the hotplate.

According to embodiments of the subject matter of the invention, the radiant grill burner is made of a Tubular ring designed, the inward or outward-facing flame outlets and above it Has incandescent honeycombs that are partially or completely covered at the top. In this way, from the incandescent honeycomb radiation grill device acting as a surface radiator

Applicant:

Küppersbusch Sd Sons Aktiengesellschaft, Gelsenkirchen

Friedrich Krullmann, Gelsenkirchen,
has been named as the inventor

from intense heat radiation directed at the food below.

According to other embodiments, the incandescent beam honeycombs are, depending on whether the flames are radial are directed inwards or radially outwards, designed as a solid or as an annular disc.

According to a further embodiment, the radiant grill burner is designed so that his The center of gravity including the top cover is in the axis of the load-bearing burner head. This makes special stabilizing and sealing agents superfluous; all that is needed is the plug connection of the two machined ring surfaces of the torch body and the base.

It is also provided that the sum of the free cross section of the flame outlet openings in the Pipe ring is equal to or larger than that of the narrowest free cross-section in the burner body. Through this a suction effect is achieved when the gas-air mixture is burned instead of a jam, and thereby the escape of the gas-air mixture on the sealing surface of the plug-in connection is avoided.

It is also provided that the incandescent beam honeycombs are curved downward in the center. This achieves that the edge zone shines bright red and the middle one only shines dark red. This becomes the fact It is taken into account that the cooling of the food to be grilled is greater in the outer zone than in the central area and thus a larger area is uniform is grilled.

In the drawing, the object of the invention is shown in two exemplary embodiments, it shows Fig. 1 is a side view of a first embodiment of the grill device according to the invention,

FIG. 2 is a plan view of the object according to FIG. 1,

009 647/27

Fig. 3 shows another embodiment and

FIG. 4 shows a plan view of the object according to FIG. 3.

The grill device shown in FIGS. 1 and 2 consists of a conventional hotplate with pan support webs 1, burner body 2 and burner head 3. In the cavity of the burner head 3 is a burner attachment 4 used, which consists of the foot 5, the connecting pipe 6, the circular pipe ring 7 with Flame outlet openings 8, the incandescent beam honeycombs 9 arranged between the tubular ring and the There is webs 11 for placing the incandescent beam honeycombs 9 on the tubular ring 7. Between the pipe ring 7 and the incandescent beam honeycombs 9 is the annular gap 12. The incandescent beam honeycombs 9 are up through the cover plate 10 covered and thus secured against heat loss upwards.

The cover plate 10 has a bulge 14, which is used to set up pots or the like. to prevent the cover plate. Drawer holes 15 are provided in the center ao area of the cover plate, which allow the exhaust of the combustion gases to the top. Also on the cover plate 10 screw bolts attached, which via spacers 13 as holding arms for the honeycombs 9 to serve.

The gas-tight connection between the foot 5 of the burner attachment and the burner head 3 of the burner body 2 takes place by a plug connection, which consists of a sleeve-shaped extension of the foot 5 and there is a corresponding recess in the burner head.

In the embodiment according to FIGS. 3 and 4 is above the cover plate 10 for better insulation the heat radiation upwards a further cover 18 is attached, which is curved upwards and a Has reinforcing edge 19. In the cover 18 there are vent slots 20, 21 and openings 22 - the latter for attaching a label plate 23, e.g. B. a company sign 23 - attached. Under the plate 23 there is an air gap 24. The cover plate 10 is attached to the cover 18 by two screws 25 tied together. Cover plate 10 and cover 18 are through heat-insulating discs 26 at the screw points separated from each other. The spacer supports 29 connect the incandescent beam honeycomb with the cover plate 10 and are held by the two screws 25 on the latter, while they are only clamped to the glow beam honeycomb are.

The grilling device according to the invention is handled in the following way:

With a gas hob, you lift the burner cover off the burner head of the burner body and sit down To do this, insert the burner attachment with a single movement, which also carries the radiant ceiling. Will the Gas is supplied to the burner in the usual way and the gas is ignited on the pipe ring in just a few seconds the glow beam honeycomb is heated to a dark red color, so that the grilling process is possible without preheating.
