Definitions
- the invention relates to a method for producing a glass ceramic hob for gas cooking appliances, which has bores for receiving the gas burners and structures deviating from the plane.
- the invention further relates to a glass ceramic hob for gas cooking appliances produced by this method.
- Cooking hobs with gas burners for gas cooking appliances are typically manufactured according to the prior art from enamelled sheet metal, from stainless steel sheet or from hardened flat glass. It is also known to produce such cooktops from glass ceramic, which has not only aesthetic but also technical-functional advantages, such as better durability and better cleaning behavior. An increasing distribution on the market for these cooktops made of glass ceramic material is evident.
- a disadvantage with regard to the cooktops produced using the methods mentioned is, on the one hand, the low degree of deformation and the limited possibility of imaging, in particular sharp-edged shapes or narrow radii.
- a thinning of the wall thickness depending on the degree of shaping is unavoidable. This has a particularly disadvantageous effect if the deformations are in mechanically and thermally stressed zones, e.g. in the edge of the gas burner bushing, the pan support fixtures, etc.
- the invention has for its object to carry out the method described at the outset or to design the glass-ceramic cooktop mentioned at the outset in such a way that a diverse shape geometry and a more constructive design of the cooktop can be achieved.
- This object is achieved on the basis of the method for producing a glass ceramic KDchulde for gas cooking appliances according to the invention in that a molten glass batch is fed to a mold which is designed according to the negative of the geometry of the hob to be formed and that the green compact pressed in this way subsequently is ceramized.
- the object is achieved according to the invention in that it is a pressed part with one piece Geometric structures deviated from the plane and formed bores by molding from the melt.
- a hob which is produced from a glass batch by the pressing known in the glass industry, does not have the disadvantages of the prior art described above. On the contrary, in addition to the significantly higher degree of forming, it is also possible to set different wall thicknesses at any point simply by designing the mold shape, and thus to obtain a constructive design of the hob that is suitable for the stress.
- the invention relates particularly to the manufacture of a glass ceramic hob (cooking surface) for gas cooking appliances and the product of the hob produced thereby, i.e. on very large parts with large dimensions (typically 60 cm x 60 cm) with a sophisticated geometric configuration, i.e. with holes for gas burners, with special edge designs for attaching the cooking surface and other structures that deviate from the cooking surface level.
- the glass ceramic hob for gas cooking appliances can either be designed in such a way that the edge of the hob is integrally thickened and adapted to the shape of a worktop or in such a way that the edge is flanged like a frame downwards or upwards by 90 ° is, the lower end face of the frame-like edge forms the footprint of the hob on the worktop or the stove housing.
- a pan support is necessary, which must be set up in a predetermined position relative to the burner on the hob.
- a defined fixation of the pan support with connection elements is possible, which have been integrally molded directly onto the cooktop by pressing.
- the hob has an opening 2 for receiving the burner head of an atmospheric gas burner (not shown), i.e. of a gas burner with an open flame.
- the hob according to the invention can, however, also be placed on gas radiation burners, which are positioned below the glass ceramic hob, with exhaust gas channels for the removal of the hot combustion gases.
- the edge 3 of the opening 2 is expediently thickened and raised, which can be achieved very easily by appropriate design of the mold geometry, in order to be able to better withstand the mechanical stress on the one hand and, on the other hand, through the flaring in of overflowing cooking material or cleaning fluid to avoid in the opening 2 and thus in the hob inside.
- Parts of the burner structure, in particular the mixing chamber, can also be formed as molded parts of the hob (not shown).
- the edge of the hob can also be geometrically shaped in accordance with the installation requirements.
- the edge 4 is thickened and adapted to the shape of the worktop 5.
- the edge can also, as shown in the right half of the drawing, be an upwardly or downwardly flanged, molded frame-like edge 6, so that it also consists of glass ceramic and forms the connection to the stove or worktop 5 without further finishing.
- edge processing as is customary with rolled material, and on the other hand, separate framing of the hob is superfluous. This makes the hob more economical due to the lower vertical integration.
- connection elements 7 for fixing pan supports or entire pan supports, switch borders, scales and decorative elements can be molded on with little effort.
- the pressed glass ceramic cooktop 1 shown in the drawing is first formed according to the pressing methods known in glass technology from a glass batch which is removed from a melt and then fed to a press mold which corresponds to the negative of the geometry to be shaped.
- the pressed glass ceramic hob is first brought to a temperature level with a high nucleation rate and then to a temperature level with high crystal growth in an oven.
- care must be taken to ensure homogeneous heating and, depending on the embodiment, the part must be supported at as many places as possible by ceramic or metallic support elements. Indirect electrical heating is also possible.
