Description

The present invention relates to a gas hob with a hob plate, a pot carrier and a support plate for gas burners. Gas hobs are produced, for example, as part of stoves or as integratable gas hobs in kitchen worktops. Several gas burners are arranged in the hob, which can be controlled via controls. To keep the food containers, such as pans or pots, at a suitable distance from the burner flame, pot carriers are provided. The pot carriers are usually connected to the gas hob and create a support surface for food containers.

The US 5,345,062 A shows a burner assembly for a gas stove. A cooktop panel includes openings for receiving drip plates. The outer contour of each drip plate has a flange that engages over the respective opening. The inner part of the drip tray is bulged to a tub that fits into the opening. The boundary between the flange and the trough is formed into a concave peripheral edge. The tub has a centered burner hole for receiving a gas burner. The burner assembly further includes a pot carrier.

In particular, when using different types of burners in a gas hob, the distance between the support surface for Gargutbehälter of the burner flame must be optimally adjusted so that an efficient heat transfer from the burner can be done on the food. A particular difficulty is also to create an aesthetically pleasing bearing surface over several burners in a gas hob with different burners. Usually therefore specially adapted to the gas burner pot carrier are used. This can lead to the case of a gas hob or a gas hob, several types of pot carriers are necessary. For reasons of production economy, however, it is better to have as few different modules as possible.

Against this background, an object of the present invention is to provide an improved way to create a gas hob with a flat pan support surface.

Therefore, a gas hob with a cooktop panel having at least one opening for a gas burner, with at least one holding plate, which includes an opening for mounting the gas burner and a peripheral outer edge with a polygonal outline, is proposed. The holding plate includes an opening for mounting the gas burner and a peripheral outer edge with a polygonal outline or a polygonal contour. The holding plate has a step from the outer edge in the direction of the opening. The gas hob comprises at least one pot carrier with a standing surface of the pot carrier forming polygonal frame, wherein the frame is placed positively on a portion of the peripheral outer edge of a holding plate.

The holding plate allows on the one hand with its polygonal plan that pot carrier can be placed with a suitable frame form-fitting manner on the holding plate. On the other hand, by the edge, which may also be curved or curved, the installation position of a gas burner with respect to its height relative to the peripheral outer edge or a hob plate can be adjusted. In this respect, the holding plate allows that even with different gas burners always the same type of pot carriers can be used.

A misorientation of the pot carrier and retaining plate is practically excluded by the angular design, since a rotation or displacement is not possible. Compared to conventional brackets, no additional pins for embossing or indentations for pan supports are necessary, so that a particularly easy to clean solution and an aesthetically pleasing overall impression of each hob is achieved.

Preferably, the outline is rectangular and in particular square. The step can be rounded or curved.

The holding plate is made in one piece of material in one embodiment. As materials, for example, metal plates, but in principle also other materials in question.

Preferably, the retaining plate has a substantially smooth surface and no indentations or noses along its peripheral edge. The corners of the polygonal plan or outline may be rounded. In this case, the holding plate may be configured such that an area along the outer edge is formed for resting on a hob plate. In this respect, the holding plate can be inserted in or on an opening in a hob plate.

In one embodiment, the retaining plate is embodied as a heat shield in the manner of a polygonal disk for thermally shielding a hob plate. In the embodiment as a heat shield, it is prevented that, in particular, a cooking surface plate made of glass ceramic or hard glass is damaged by heat reflected from bottoms of food containers.

The gas hob comprises a cooktop panel having at least one opening for a gas burner, and at least one holding plate, which comprises an opening for mounting the gas burner and a peripheral outer edge with a polygonal outline. In this case, the holding plate has a step from the outer edge in the direction of the opening. The holding plate is in particular, as described above, executed.

An area along the outer edge of the retaining plate rests on the hob plate. In one embodiment of the gas hob, the opening of the holding plate extends below a hob plate surface. This ensures that, in particular, particularly powerful burners, such as Wokgas burners, can be arranged lower than other gas burners of the gas hob. At the same time, a uniform level of a bearing surface over the entire gas hob can be achieved by similar pot carriers. Due to the stepped design of the retaining plate, it is possible to always achieve the most favorable distance between flames and bearing surface of the pot carrier used.

Preferably, therefore, the gas hob has a plurality of openings for a plurality of gas burners and holding plates. The holding plates all have the same outline. This makes it possible that the same pot carrier can be used.

The gas hob comprises at least one pot carrier with a standing surface of the pot carrier forming polygonal frame, wherein the frame is placed positively on a portion of the peripheral outer edge of a holding plate.

It can thus achieve a particularly simple connection between the pot carrier and the heat shield. There are no pins or stampings necessary to ensure the orientation of the pot carrier on the heat shield. In addition, only similar pan supports are to be kept in the production.

It is possible that one or more pot carriers are placed as a Mehrfachtopfträger on adjacent heat shields or holding plates.

In particular, the respective pot carrier may have a frame which surrounds the gas burner and which has a section resting on the hob plate and a section resting on the heat shield. In this respect, an edge of the pot carrier rotates around the angular contour of the heat shield or the holding plate and terminates flush.

The pot carrier may each have inwardly directed fingers which form a support surface for a food container.

In a preferred embodiment of the gas hob, a plurality of pan supports, each of which forms a support surface for a food container in the region of a gas burner, are provided, and the support surfaces are at the same distance from a hotplate surface. The pot carriers are preferably the same.

Preferably, the hob plate is further at least partially made of hard glass or glass ceramic. These materials allow a particularly appealing aesthetic appearance of the gas hob. In particular, tempered glass or glass ceramic have little deformation with temperature changes during operation of the gas burners. It is therefore particularly easy to provide a level glass ceramic hob plate.

The gas hob may also be formed with a cooktop panel in the manner of a cooktop tray, for example of molded material such as stainless steel. Cooker sinks, but also normal flat hobs can be used for example in a kitchen countertop or a cooker. Preferably, then the metal sheet is glued underneath with a hard glass or glass ceramic plate. The hard glass or glass ceramic plate then largely prevents deformation as a function of temperature changes of the metal sheet.

Further possible implementations of the invention also include not explicitly mentioned combinations of features described above or below with regard to the exemplary embodiments. The expert will also add individual aspects as improvements or additions to the respective basic shape of the holding plates or the gas hob.

Further advantageous embodiments and aspects of the invention are the subject of the dependent claims and the embodiments of the invention described below. Furthermore, the invention will be explained in more detail by means of preferred embodiments with reference to the attached figures.

In the figures, the same or functionally identical elements have been given the same reference numerals, unless stated otherwise.

In the FIG. 1 is a schematic cross-sectional view of an embodiment of a holding plate shown. The FIG. 2 shows a plan view of the holding plate. By means of Retaining plate can be gas burners suitable in or attach to openings of hob plates.

Therefore, in the FIG. 1 a hob plate 6, for example, made of glass ceramic. The hob plate 6 has an opening 15 into which a gas burner 3 is to be inserted. The gas burner 3 pierces the opening 15 upwards, so that above the glass ceramic plate 6 burner flames 9 can heat a cooking product container. Below the hob plate 6 fittings or leads to the gas burner 3 are provided.

It can be seen a holding plate 1 with a square outline, as shown in the FIG. 2 is indicated. The holding plate 1 also has a central opening 2, on or in which the gas burner 3 is mounted. The holding plate 1 makes it possible, by its shape, in particular by a step 5, between the outer edge 4 and the opening 2, to set gas burner flames 9 in flexible height. In the presentation of FIG. 1 the opening 2 is located lower than the hob plate 6. Thus, a distance of burner flame 9 can be optimally adjusted to a potential support surface 8 for Gargutbehältnisse.

FIG. 1 further shows a pot carrier 7, which is positively placed on a portion 11 of the peripheral edge 4 of the holding plate 1. The pot carrier 7 has inwardly, ie in the direction of the burner 3, projecting fingers 10, the tops of which form a bearing surface 8 for Gargutbehältnisse. Depending on the severity of the bend, the bend or step 5 of the holding plate 1, a distance 12 between the flame 9 and the support surface 8 can be adjusted depending on the gas burner 3 used. It is not necessary to change the nature of the pot carrier 7. In this respect, in the execution of the holding plate 1 as a polygonal disk with a level 5 in a corresponding gas hob identical pot carrier 7 can be used.

In the FIG. 3 an embodiment of a gas hob with holding plates is shown in perspective. The FIG. 4 shows a plan view of the embodiment of the gas hob. The Figures 3 and 4 show a built-in hob with a hob plate 6, for example, printed glass ceramic. There are four gas burners 21, 22, 23, 24 are provided which pierce both openings in the hob plate 6 as well as openings in the provided holding plates 16, 17, 18, 19. There are also controls 20, as control knob provided with which the performance of the various burners 21-24 can be controlled.

One recognizes in particular in the FIG. 4 in that the gas burners 21, 22, 23, 24 are arranged in the quadrants of the rectangular hob plate 6. Furthermore, the holding plates 16, 17, 18, 19 all have the same floor plan. The provided in the upper right quadrant gas burner 22 is a wok burner with very high power. This burner 22 requires a distance between the burner flames and a support surface for Gargutbehältnisse such as pots or pans or a wok, which is different from the distances between gas flames of the burner 21, 23, 24 to the support surface. Therefore, the holding plate 17 is provided with a step, so that the gas burner 22, which is attached to the holding plate 17, is slightly lower. This ensures that, despite the different burner power or a different type of burner for all gas burners 21, 22, 23, 24 of the gas hob 13, the same pot carrier can be used.

This is in the FIG. 5 shown in plan view. The holding plates, which are designed as heat shields for the glass ceramic 6, each have a square frame 29, which forms their base. The frame 29 of the pot carrier 25, 26, 27, 28 is shaped such that it can be positively placed on the peripheral edges 4 of the heat shields 16, 17, 18, 19. In this case, the pot carriers are mounted in a non-rotating and slip-proof manner in the areas of the gas burners 21, 22, 23, 24. From the frame 29, fingers at 10 point inwards and form with their tops the bearing surface for pots and pans or the like.

The FIG. 6 shows a schematic cross-sectional view of the embodiment of the gas hob along a section axis AA. In the orientation of FIG. 6 on the left, the front right gas burner 23 is shown. On the right you can see the Wokgasbrenner 22. Both gas burners 22, 23 are fixed by means of a holding plate 17, 18, which are designed as a heat shield for the glass ceramic plate 6. The holding plate 18 is designed in the manner of a flat quadrangular disc.

However, the holding plate or the heat shield 17 has in the direction of the gas burner 22, a step 5, the total offset the gas burner 22 in the downward direction. As a result, the distance between the gas burner flame and the bottom of a Gargutbehältnisses 14, such as a saucepan, optimally met.

You see in the FIG. 6 Furthermore, that the bearing surfaces 8 of the pot carrier 25, 26 have the same level with respect to the glass ceramic cooking field plate 6. The two pot carriers 25, 26 are also the same.

In the FIG. 7 is a further cross-sectional view along the section AA indicated. The heat shields or holding plates are shown hidden. It can be seen that the surface 30 of the hob plate 6 and the bearing surfaces 8 of the pot carriers 25 and 26 are equally spaced. Furthermore, it can be seen that the respective frame 29 of the pot carrier 25, 26 rests positively on the cooking surface plate surface 30. The frame 29 thus forms a pot carrier stand surface 31.

Finally, in the FIG. 8 a perspective view of the gas hob 13 indicated. One looks in the orientation of the FIGS. 4 and 5 laterally from the right onto the gas hob 13. The pot carriers 28 and 29 (cf. FIG. 3 ) are removed. The design of the holding plates with a step or bend, which allows gas burner offset in height to each other in the cooking surface plane can be arranged, creates a particularly appealing and uniform image for the gas hob 13. In particular, the support surfaces all have the same level or the same Distance with respect to the hob plate 6. Because the holding plate is used for example as a heat shield, and at the same time allows the correct distance of the gas burner flame to a pot carrier support surface or from the hob surface, same pot carrier can be used. In this respect, a gas hob, as indicated in the present figures, can be produced more cost-effectively than conventional gas hobs.

Although the present invention has been described with reference to embodiments, it is variously modifiable. In particular, the said materials for the hob plate can be varied. The pot supports can have a wide variety of materials. In particular, it is possible to make the same of cast iron or at least partially made of stainless steel or enamelled steel. The holding plates can also have other than square shapes. Of course, other numbers of gas burners in a gas hob are conceivable as shown.
