Description

Hob arrangement

The present invention relates to a hob arrangement. Modern built-in hobs usually include a hob plate for receiving and fixing the actual cooking areas, such as gas burners, and pot carrier. The hob plate is used for example in a countertop and should be as flush as possible. In the past, cooktops have been made, for example, from stainless steel or hard glass or glass ceramic. In order to secure the pot carrier against slipping on the hob plate, especially in gas hobs, then holes in the glass or special stampings in a stainless steel plate are necessary. Disadvantages are corresponding complex production methods with additional attachment steps. In addition, usually additional fasteners such as pins, screws or the like additional mudflaps and elements that increase the cost.

Against this background, an object of the present invention is to provide an improved hob assembly. Accordingly, a hob arrangement is proposed, which is designed for example as a gas hob. The hob arrangement comprises a hob plate with an opening for at least one gas burner, wherein the hob plate at least one recess and / or a projection for holding the pot carrier comprises. The hob plate is at least partially made of a ceramic material.

Through the use of ceramic materials for the hob plate recesses or projections during the manufacture of the plate can be easily realized. In the hob arrangement, the hob plate can be provided by a material removal with a recess. It is also conceivable, however, to produce the recess or also projection by shaping a raw plate from a homogeneous paste of the starting material and subsequent solidification, eg sintering. In one embodiment, the cooktop panel comprises cordierite. For example, the cooktop panel is at least partially made of synthetic cordierite, cordierite chamotte or aluminum titanate. By cordierite is meant in particular a mineral from the mineral class of silicates.

Corresponding mineral materials can be easily shaped and made into cooktop panels. For example, the mineral raw material is kneaded into a paste and preformed by, for example, extrusion. Recesses or projections can be made before sintering to the finished hob plate. A corresponding hob plate for the hob arrangement can then be realized in particular materialeinstückig.

In an alternative embodiment, the hob plate comprises a plurality of superimposed plates. For example, the plates may have such different contours that the recess or the projection of edges of the plates are enclosed. Preferably, the plates are connected to each other. In this case, a lamination or bonding of the plates can be provided.

Embodiments of the hob arrangements provide that the recess and / or the projection is arranged around the opening for the gas burner. For example, a plurality of recesses may be provided around the opening for the gas burner. A suitably shaped pot carrier can then be coupled to the recess or to the projection, preferably with positive locking, so as to be slip-proof. In one embodiment of the hob assembly, the projection has an angular raised surface around the opening for the gas burner. For example, a square raised surface may be provided around the gas burner. A frame for the pot support, which is adapted in geometry to a raised square surface, then provides a slip-proof connection with the projection.

In further embodiments, the recess may be designed, for example, as a groove or groove around the opening for the gas burner. For example, if a square, provided for the opening for the gas burner groove incorporated in the hob plate, the pot carrier used with suitable spring elements can be provided on the underside be, so that tongue and groove mesh and a simple attachment of the pot carrier is realized.

Preferably, the hob assembly further comprises a pot carrier. The pot carrier is equipped with at least one holding section for positive engagement with the recess and / or projection.

For example, the pan support includes a pan support frame for resting on the hob plate and for engaging the recess or enclosing the projection. It is also conceivable that the pot carrier comprises several feet for insertion in recesses in the hob plate. The recesses can be made for example in the geometry of blind holes, but also any geometric cross-sections. In particular, the use of the glass-ceramic material allows, for example, recesses with quadrangular cross-sections. In these square recesses, the pot carriers can be plugged.

In a preferred embodiment of the hob arrangement, the pot carrier comprises a plurality of angle elements each having a first leg and a second leg. Here, the first legs are inserted substantially vertically in recesses of the hob plate and the second leg form a support surface for a food container. The second legs are, for example, fingers which point inwards in the direction of the flame of the gas burner. The hob arrangement preferably comprises at least one gas burner. The hob arrangement can be used as a built-in hob or as part of a stander.

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.

The cooktop assembly 1 comprises a cooktop panel 2, which is, for example, in or on a work surface 3. The hob plate 2 is made of a ceramic material. Ceramic materials are, for example, starting mixtures with magnesium silicate hydrate, kaolinite, calcined kaolinite and / or pure aluminum oxide. The hob plate can also be made in particular of high-purity synthetic cordierite. In particular, the aforementioned mineral silicates allow the production of the hob plate with a starting mixture of a homogeneous paste, which can be brought into the desired shape for the hob plate.

In the illustrations, the hob plate 2 is made in two parts, with a first portion 2A for receiving gas burners 4, 5 is provided and a second part 2B for receiving controls 6 and 7 displays the hob assembly 1 includes two gas hobs with gas burners 4, 5 , which are provided with pot carriers 8, 9. The pot supports 8, 9 in this case comprise a frame 14 which is placed on the hob plate 2. Inwardly directed from the frame 14 fingers 13 form a Support surface 16 for a food container, such as a pot or a pan. In order to secure the pot carrier 8 or 9 against slipping on or on the hob plate 2, 5 recesses 15 in the hob plate 2 are provided to the gas burner 4, 5 or the openings not shown here for the gas burner. The recesses 15 are formed as a square circumferential groove, which are adapted in shape and geometry to the frame of the pot carrier 14.

In Fig. 1 B it can be seen that the frame 14 of the pot carrier 8, 9 can be positively inserted into the recesses 15. This results in particular a flush completion of the surface of the hob plate 2 with the frame 14 of the pot carrier 8, 9. Advantageously, no additional attachment mechanisms for the pot carrier 8, 9 on the hob plate necessary. It also gives an aesthetically pleasing impression. In the cross-sectional view of Fig. 1 C can be seen the groove-shaped recesses 15 in the hob plate 2, in which the frame 14 of the pot carrier 8, 9 are used. Fig. 1 C also shows the support surface 16 for depositing cookware on the fingers 13 of the pot carrier. Furthermore, the opening 17 for the gas burner 4 is indicated. 2, a second embodiment of a hob arrangement 10 is shown in perspective. It can be seen again a two-piece hob plate 2, which is in or on a worktop 3. In the orientation of FIG. 2 towards the front, a control panel section 2B with control element 6 and display devices 7 is shown. The pot supports 8, 9 are similar to the pot carriers, as shown in FIG. 1 executed. Around the two gas burners 4, 5 around square raised surfaces 18 can be seen as projections of the hob plate 2. The square raised surfaces 18 are enclosed by the frame 14 of the pot carrier 8, 9 in the mounted state. 3 shows a third embodiment of a hob arrangement 1 1 with a ceramic hob plate 2. The hob plate 2 in turn comprises two sections for the gas burner 2A and a section 2B for a control element 6. The hob plate is in a worktop 3 a or put on. To the two gas burners 4, 5 or to the not visible in Fig. 3 openings for the gas burners 4, 5 around, are rectangular Recesses 15 indicated in the hob plate 2. In the recesses 15 can be inserted or put pot carrier feet 19. The indicated in FIG. 3 pot carrier 8, 9 in this case have cross-shaped bearing surfaces for food containers, the feet 19 extend vertically downwards in the direction of the hob plate 2. The recesses or openings 15 in the hob plate 2 are designed such that the foot elements or pot carrier feet 19 can be inserted. This results in a slip-proof and twist-proof arrangement of the pot carrier 8, 9 without additionally necessary fastening mechanisms. Finally, FIG. 4 shows a fourth embodiment of a hob arrangement 12. Again, a hob plate 2 is inserted in or on a worktop 3. In this case, an area 2B for operating elements 6 and the area 2A for the gas burners 4, 5 are provided. Around the gas burners 4, 5 or the openings in the glass ceramic sheet 2A around substantially square recesses or openings 15 are arranged. The pot supports 8, 9 are each formed from four angle elements 23. A respective angle element 23 has a first and second leg 24, 25. The legs 24, 25 have a substantially square cross-section. The angle elements 23 can be used with the first leg 24 perpendicular to the respective recess 15 of the hob plate 2. For this purpose, optional holding inserts 26 are provided, which are set in the openings 15 for stabilization and which enclose the vertical legs 24. In this respect, the first leg 24 extends perpendicular to normal operating state of the hob assembly 12. At right angles, ie horizontally to the second leg 25 of the Wink elements 23 and form a support surface 16 for the respective food containers.

The depth or size of the rectangular recess 15 for inserting the first leg 24 of the angle elements 23 can be chosen such that a sufficient stability of the inwardly directed fingers or second leg 25 is ensured.

In Fig. 5 is a cross-sectional view of a multi-part hob plate 2 is shown. 5 shows a first plate 20 and a second plate 21. The two plates 20, 21 may be made of glass ceramic or mineral material and fastened to each other. This can be a lamination, gluing or other connection. In order to achieve a recess in the two-layer or two-layer hob plate 2, the second plate 21 is interrupted, so that the edges 22 of the second plate define a contour of the recess 15. Fig. 6 shows a cross-sectional view of a material integral cooking plate 2 with projections 18 A, 18 B.

Finally, Fig. 7 also shows a multi-layer or multi-layer cooktop panel 2 with a lower plate 20 to which an upper second plate 21 A, 21 B is attached. The contours of the second plate 21 define the projections of the entire hob plate 2. It can be seen that the edges 22 of the second upper plate 21 specify the shape of the projections.

The cross sections or profiles of the cooktop panels 2 can be easily realized in terms of manufacturing technology, especially when using ceramic materials. This is especially the case with the use of cordierite, since during production first a paste is produced, which can be adapted to the desired shape and the desired profile of the hob plate. In this respect, for example, results in a material integral cooking plate with recesses and / or projections, which can serve for the attachment of pot carriers. By dispensing with additional retention mechanisms, the manufacturing cost of the entire hob assembly can be reduced. In addition, a particularly appealing visual appearance of the hobs can be realized. Although the present invention has been described with reference to embodiments, it is variously modifiable.
