The reflection surface with its concave curvature continuously extends from the former gas burner to the latter gas burner. The connectors are arranged along longitudinally extending symmetric axis of the cover plate.

Description

Technical area

The The present invention relates to a gas hob according to the The preamble of claim 1. Here, the gas hob a gas well or be part of a gas stove.

State of the art

As in 4 shown, the cover plate, the so-called top sheet, a gas hob is usually flat. This has the disadvantage that the rays of the heat generated by the gas burner are reflected on the top sheet in all directions and a part of the radiated heat from the gas burner is lost as scattered radiation.

To avoid such stray radiation heat losses suggests the document DE 28 44 091 A to surround the combustion nozzle of a gas stove with a curved towards the cooking ring reflector ring. Furthermore, from the document DE 2 211 961 A a Tischplattenheizvorrichtung with a gas burner and surrounding the gas burner concave, hemispherical drip pan known. In order to reflect infrared radiation sent from the gas burner to the drip pan upwards to the heating plate, the surface of the concave drip pan is provided with a reflection layer. Furthermore, from the document DE 78 23 999 U1 a trained for reflecting the heat radiation reflector known which is concavely curved to the gas burner and surrounds it annularly.

A hob according to the preamble of claim 1 is from the document DE 1 629 933 A known. The gas burner of this hob is surrounded for better utilization of heat energy with a shaped like a parabolic reflector. The gas flame burns in a capsule-like diffuser centered in the reflector, the heat rays emitted by the diffuser being reflected by the parabolic mirror vertically upwards, for example in the direction of the bottom of a pot.

The from the aforementioned publications DE 28 44 091 A . DE 2 211 961 A . DE 78 23 999 U1 and DE 1 629 933 A known reflector arrangements surround the gas burner respectively in the manner of a paraboloid or in the manner of a hemisphere, so are bent in all horizontal directions. Thus, the reflector arrangements known from the prior art can be used exclusively in a gas hob with only one gas burner centered in the reflector arrangement.

Best way to execute the invention

In order to avoid superfluous repetitions, the following explanations concerning the embodiments, features and advantages of the present invention (unless stated otherwise) refer to both the 1 illustrated gas hob 100 as well as on in 2 illustrated gas hob 102 as well as on in 3 illustrated top sheet 14 or to the in 3 shown cover slat 14 ,

I'm referring 1 illustrated first embodiment of the present invention is a gas hob 100 , namely a gas well, with at least two in the longitudinal direction of the gas well 100 juxtaposed gas burners 60 shown. To connect the above the reflection surface 20 arranged gas burner 60 indicates the upper area of the gas well 100 , the so-called top sheet 10 , a first 50 and at least one more 52 (see. 3 ) Gas burner connection on. As in 3 2, the gas burner connections are arranged along a longitudinal axis L, namely along the longitudinally extending symmetry axis of the gas hob. The top sheet 10 , is in support of the gas burners 60 emitted radiant heat concave shaped and reflecting heat radiation reflecting surface 20 educated.

In contrast to the, from the discussed in the chapter state of the art publications DE 28 44 091 A . DE 2 211 961 A . DE 78 23 999 U1 and DE 1 629 933 A known gas wells is the reflection surface 20 of in 1 illustrated top sheets 10 not spherically shaped, but extends with its concave curvature throughout the gas burner connections 50 . 52 , Thus, the heat radiation of the juxtaposed gas burner 60 be used optimally.

By the shape of the top sheets 10 the radiant heat of the gas flame is not as in the case of 4 State of the art radiated on all sides, but bundled and concentrated upwards towards the bottom of the pot. Thus, more heat is on the pot than flat-shaped gas wells.

Also when in 2 illustrated second embodiment of the present invention is the reflection surface 20 of the top sheets 12 similar to a concave mirror around the longitudinally extending symmetry axis L of the top sheets 12 arched inwards and reflects from the gas burners 60 emitted heat rays bundled on the bottom of the pot. The cooking vessel, such as a pot or a bowl, is at the in 2 illustrated gas well 102 on a support element 80 supported.

Subsequently to his raised margins 21 . 22 has the top sheet 12 each a flat, horizontally extending area 30 . 32 on. This flat area 30 . 32 is preferably of the same material as the reflective surface 20 , for example made of stainless steel, formed and easily washable. On one 30 This flat areas is to operate the gas well an operating and / or display element 70 arranged.

As in 3 shown, the flat area 30 . 32 be slightly inclined down, giving the user the operation or reading the control and / or display element 70 facilitated.

This in 3 illustrated third embodiment of a top sheets 14 according to the present invention has two on the transverse sides of the curved reflecting surface 20 arranged strips or edges 24 for collecting liquids. These crossbars 24 extend between the longitudinal side edges 21 . 22 , For aesthetic as well as economic reasons run the cross bars 24 preferably for collecting liquids from above, so that they are in a plane with the side edges 21 . 22 to lock. The crossbars 24 can be integral with the curved reflecting surface 20 formed, for example in the curved reflection surface 20 be formed.

Further, in the curved reflection surface 20 four recording areas 23 molded for receiving pot carriers. These recording areas 23 extend substantially parallel to the longitudinal side edges 21 . 22 ,

For supplying primary air to the respective gas burners 60 has one 32 which adhere to the raised margins 21 . 22 subsequent flat areas 30 . 32 of the top sheets 14 one in the longitudinal direction of the top sheets 14 extending primary air supply 40 , namely a longitudinal or longitudinal edge having air openings.

The in the 1 to 3 illustrated top sheets 10 . 12 . 14 differ from known from the prior art top sheets in particular in that the arched in the manner of a concave mirror reflection surface 20 not spherically shaped, but only curved in one direction, namely is curved around the axis of symmetry L.

Another advantageous demarcation criterion compared to the prior art is that the reflection surface 20 over all gas burner connections 50 . 52 extends. In this way, a radiation-supporting top sheet for any number of gas burners 60 provided.
