Either electrically or gas heated

Hotplate

The innovation relates to a hotplate that can be heated either electrically or with gas for a cooking appliance or the like a gas burner arranged in the center of a ring-shaped, electrically heated cooking body.

A hotplate of this type is the subject of DE-PS 21 27. In this hotplate, the electrically heated cooking body consists of an annular cast plate, through the center of which the gas burner protrudes during its operating position. In order to maintain the correct distance between the gas burner and the bottom of the cooking vessel, it is necessary here to assign a grid-like cooking vessel support device to the cooking area. Furthermore, it is necessary, so that the cooking vessel can come into good thermal contact with the electric cooking body when it is used, to hold the gas burner so that it can be lowered in the vertical direction. However, if this type of hotplate is used, the constructive effort is considerable.

The object of the innovation is therefore to further simplify the construction of the hob of the type mentioned at the beginning.

The solution to this problem according to the innovation can be found in the characterizing part of claim 1.

Appropriate refinements of the innovation are set out in the subclaims specified.

The innovation creates a hotplate that is very easy to handle and operate and which allows optimal use of the advantages of cooking with gas and electrical energy during a cooking process.

An embodiment of the innovation is in the drawing and is described in more detail below on the basis of this.

With 1 is a so-called. Designated hob of a cooking appliance not shown, in which a hob 2 is arranged. The hotplate 2 consists of a conventional gas burner 3 and an electric cooking body 4 located above the gas burner, on which a cooking vessel 5 is placed. The gas burner 3 is inserted in the center of the hob bottom 1 'and its height corresponds approximately to the depth of the hob. The electric cooking body 4 is formed from a plurality of electric tubular heating element parts 6 to 11. Each of the tubular heating element parts 6 to 11 is roughly

formed fen-shaped. The individual loops 12, 13 of these radiator parts, which are arranged in a star shape, open into a central distributor 14 to which they are attached in a moisture-proof manner and connected electrically in series. The individual loops 12, 13 are designed so that the upper loop 12, on which the cooking vessel 5 stands, has an electrical heating coil M- ¹ , while the lower loop 13 only serves to return the electrical heating coil M- " jacket tube radiator parts 6,7,8,9 and 10 are bent at the reversal end 15 in the direction of the cooking hob towards the edge and are in a prescribed therein, circumferential indentation 16 a support. It is thus achieved that the star-shaped electric cooking body M during operation of the cooking point with a gas at the same time The one tubular heating element part 11 is guided through the trough wall 1 ″ to the electrical supply line and is correspondingly sealed there with a pivotable sealing body 17. In order to clean the hob 1, the electric cooking body 2 can be folded up by approximately 90 ° in a known manner by means of the pivotable sealing body I7.

Claims (4)

1. Electrically or gas-heated hob as required for a cooking appliance or the like with an electrically heated cooking body in the center of a ring-shaped structure arranged gas burner, characterized in that the electrically heated cooking body (4) consists of several tubular heating body parts (6 to 11) is formed, which are summarized in a star shape and in the edge region of the hotplate (2) in a circumferential impression (16) are supported. 2. Cooking area according to claim 1, characterized in that the tubular heating element parts (6 to 11) are loop-shaped are formed and connected to a central distributor (14). 3. Cooking area according to claim 1 or 2, characterized in that the tubular heating body parts (6,7,8.9,10) are bent at the reversal end (15) in the direction of the embossing (16). 4. Cooking area according to claim 2, characterized in that the individual loops (12, 13) of the tubular heating element parts (6 to 11) are designed so that the upper loop (12) has an electrical heating coil (4 '), while the lower loop (13) serves as an electrical return (4 ") for the heating coil (4 ¹ ).
