GAS HOB

The invention relates to a gas hob with at least one gas burner that projects beyond the base area of a hob plate and with a pan support associated with the gas burner, the level of which also projects beyond the hob base area.

In a known cooking appliance with a gas hob (DE 29 29 474 A1), gas burners are arranged in the area of a hob plate that is recessed compared to the edge area and that protrude above the hob plate. More or less elongated and radially extending webs that surround the gas burners are provided as pan supports on the raised edge area and in the center between the four gas burners. These webs extend freely at a distance above the hob plate up to the immediate vicinity of the gas burners or burner covers. The disadvantage here is that the hob plate is very difficult to clean, particularly below the webs mentioned, and there is a considerable risk of injury. In contrast to this, spider-like pot supports are known, for example, which can be placed as individual parts or as individual parts on the hob plate or the individual burners. Cleaning the hob plate is no problem after removing the pan supports, but there is still a risk of injury when handling the pan supports and you need a temporary place to put the removed pan supports, which is not always available with free-standing stoves, for example. Last but not least, the presence of several individual parts makes the gas hob more expensive overall and makes it more difficult to transport and pack.

ZTP97P709

The invention is based on the object of improving a gas hob of the type mentioned at the outset in such a way that it represents a compact and one-piece construction unit, is particularly easy to clean, and the risk of injury during handling is largely excluded.
5

This object is achieved according to the invention by the features listed in claim 1.

Such a gas hob with sections carved out of the hob plate that form pot supports is particularly easy to clean due to its compactness and manual accessibility from above, i.e. the entire hob plate, including the raised pot supports, can be cleaned very easily in one wiping process without first removing individual parts. The seamless transition between the hob plate and the pot supports avoids protruding parts, sharp corners and the like, so that the risk of injury when handling the gas hob is virtually eliminated. Last but not least, the inventive design of the gas hob also results in manufacturing and price advantages compared to conventional gas hobs.

For the gas hob according to the invention with the pot support integrated into the hob plate, a glass ceramic plate, a sheet metal plate, or a cast iron plate or the like can be used as the hob plate, with known manufacturing processes being used to produce the sections projecting beyond the base area.

Further advantageous details of the invention emerge from the embodiment shown in the drawing.

The gas hob according to Figure 1 has a largely flat hob plate 2 within a peripheral frame 1, for example made of sheet metal or glass ceramic material. The hob plate has four gas burners that protrude beyond the base area 3 (see also figure) of the hob plate 2 and are limited at the top by burner covers 4. Below the burner cover 4 there is a burner pot 5 in a known manner with a gas supply through a corresponding opening in the hob plate 2. Each gas burner 6 is assigned radial, rib-shaped sections 7 and 8, each of which runs concentrically towards the assigned burners 6. In the embodiment, these sections 7/7', 8 are formed or embossed from the sheet metal material of the hob plate 2 to such a high level that their flat (Figure 2) or round (Figure 3) apex surfaces 9 extend beyond the hob plate 2 essentially to the level of the burner cap 4 or even beyond the burner cap 4 itself. These apex surfaces 9 form pot supports and shelves for pots to be placed on and above the burners. As Figure 1 shows, there are longer sections 7 between adjacent gas burners that are common to these adjacent gas burners 6, while shorter sections 8 run towards the outside of the gas hob. Essentially in continuation of sections 7, 8 and in line with these, short adjusting ribs 10 are provided on the edges and on the top of the burner cover 4, also in a radial arrangement, which slightly protrude above the burner cover 4 and on the circumference and are located at the level of the adjusting plane formed by the apex surfaces 9. These adjusting ribs also serve as a support surface, in particular for small pots.

Figure 2 shows that U-shaped protective rails 11 are placed or clamped in a suitable manner on some or all sections 7/8. These more or less long protective rails 11 protect the apex surfaces 9 of the, for example, enamelled or otherwise scratch-sensitive trough plate 2. Figure 3 indicates that air inlet openings 12 can be provided on the flanks of the sections, for example T, through which additional, for example secondary air, can reach the combustion points, as shown by arrows. In order to at least largely prevent the penetration of, for example, liquid, into these air inlet openings 12, upwardly directed screens 13 are provided on the air inlet openings 12 inside the cavity of the sections T.

As already mentioned, the trough plate can be made of any suitable material, for example, of glass-ceramic material which has the raised sections in one piece.
