Abstract

The invention relates to a hob (1) for a household appliance or the like with several cooking locations (8, 9, 10, 11, 13) of which at least one (8, 9, 10, 11) is heated by electric power and at least one other location (13) can be heated by a gas burner (14). The installation surface of all the cooking locations is formed by a ceramic glass plate (7). The plate (7) has for each gas burner (14), an opening (16) intended to receive the gas burner (14) or its inlet (15).

Description

i Cooktop

  The present invention relates to a cooktop comprising

  both multiple cooking locations, of which at least one

  location is heated by electrical energy and at least one

  the location can be heated by a gas burner and in which the laying surfaces of all the cooking locations intended to receive cooking vessels are constituted by a plate

glass or glass ceramic.

  In a known cooking appliance of this type, several burners

  their gas and at least one electric heating element per shelf-

  are arranged under a ceramic hob which transmits

  heat (DE-OS 30 49 491) Since in the case of burners

  their gas, the heat energy is transmitted to the cooking vessels

  its indirectly, via the plate in vitro-cé

  ramic transmitting heat, it is not possible to make full use of the well-known advantages of open flame cooking, in particular with regard to the reaction time during ignition

  and extinguishing the flame and also the yield.

  The object of the present invention is to improve a hob of the type indicated in the introduction on the one hand in order to obtain the

  advantages of a flat plate in terms of cleaning and use

  tion and on the other hand in order to be able to operate without limitation the

two heating modes.

  The problem is solved according to the invention by the fact that the plate

  that, for each gas burner, there is an opening for

  see the gas burner or its arrival.

  According to an advantageous improvement of the invention, the burner

  their gas protrudes above the plane of the plate and a grid which spans the gas burner is rests on said plate, in the region of the gas burner. The grid can also span several gas burners. With regard to the handling of use and maintenance, the hob according to the invention has all the advantages

  a modern ceramic hob, all places

  cooking elements being formed by a single flat plate, preferably

  rence in vitro-ceramic, which can be decorated It also allows to take full advantage of the advantages of gas cooking with a

  open flame, the plate should only include for this purpose

  relatively small dimensions for the gas burner (s) or their gas supply; advantageously, the gas burners can be arranged so that they can be inserted into the opening

and easily removed.

  In the context of the invention, the openings may comprise

  ter sealing elements, such as annular covers or

  other sealing means which seal with the burners

  their or their gas supply and prevent liquids from entering the openings The burner head concerned may protrude slightly above the plate, be aligned with it or be mounted

  slightly recessed in the opening.

  The invention is described below using an exemplary embodiment

  sation shown in the drawings These show: Figure 1, a top view of the hob,

  Figure 2, a sectional view of the hob as shown in Figure

gure 1.

  The hob according to FIGS. 1 and 2 has a flat outer peripheral frame 1 with an upper rim 2, which frame

  1 is closed downwards by a removable cover 3 A transverse bar

  dirty 4 divides the surface of the hob into a cooking zone 5 and a control zone 6 with control elements 18 arranged

  in the form of rotary knobs controlling electric switches

  for the cooking locations described below The cooking zone 5 at least is covered with a plate 7 in ceramic glass

  flat, large surface Cooking zone 5 has several

  cooking placements, namely locations of shapes and sizes

  different areas which are electrically heated and are indicated by marks 8, 9, 10 and 11 identifying their periphery, locations with which are associated, under the plate 7, heating elements 12

  electrics of a type known per se, for example heating elements

  radiant heat, as well as two gas cooking locations 13

  formed by gas burners 14 with their inlets 15 corresponding-

  tes, shown only schematically.

  In the region of the two gas burners 14, the plate 7 comprises

  door openings 16 whose size is adapted to the diameter of

  burners 14 and whose free section is slightly greater than the diameter

  meter of the burners or their heads As shown in FIG. 2, the gas burners 14 protrude slightly relative to the plate 7 There is provided, in the region of the burners 14, a grid 17 which spans the two burners 14 and rests on the baking tray 7 Cookware

  can be placed on the grate above the gas burners 14.

Claims (3)
