Definitions
- the invention relates to a hotplate with a flat hotplate body, which has a substantially flat top and underside in the heated area, and which is made of good heat-conducting, electrically insulating material with a low coefficient of expansion and high resistance to temperature changes, as well as electrical heating, which is divided into individual, mutually insulated areas made of resistance material is applied to the underside of the hotplate body and has areas with different electrical surface loads.
- Such a hotplate is known from DE-A-2411663.
- the areas of the heating consist of resistance strips of the same length, width and distance as well as the same electrical resistance.
- the isolated areas are electrically connected to one another by busbars or the like.
- Two of the busbars have a lower power density than the heating layer.
- the heating must consist of a material with a positive, linear temperature coefficient. The aim of this is to ensure that, in the case of an incorrectly placed cooking vessel, where the heat dissipation is reduced, the power density decreases due to the increase in the resistance of the special resistance material.
- a heating plate for a magnetic stirrer (DE-B-2215798), in which the heating plate has a disk made of heat-resistant insulating material, on the underside of which a flat heating conductor is printed or vapor-deposited.
- this is a heating plate that is only intended and suitable for low temperatures.
- the use of the heat-resistant insulating material is required there so that the magnetic field lines of the rotating magnetic field can pass through the heating plate.
- a suggestion to create a hotplate with operating temperatures of more than 300 ° C cannot be taken from this prior art.
- the invention has for its object to provide a hotplate of the type mentioned, which is particularly simple in construction and just as easy to manufacture, has the lowest possible heat capacity, and guarantees a very short heating time with relatively low electrical connection values.
- the invention proposes that, in the case of a hotplate of the type mentioned at the outset, the resistance value is coordinated by reducing the cross-section, in particular with the aid of a laser, the areas of different electrical surface loads are formed in a ring or a circle, and the electrical surface load increases to the outside.
- the hotplate body can be made of ceramic, for example magnesium oxide, aluminum oxide or another suitable, technical ceramic, such as KER 520. Burnt-in, reaction-bonded or hot-pressed silicon nitride can also advantageously be used. This material has a low coefficient of expansion with good thermal conductivity and exceptional resistance to temperature changes. Due to the high to sufficient mechanical strength, their high insulation values and good thermal conductivity at the same time, it is possible to make the hotplate body thin, so that the hotplate constructed in this way has a practically vanishingly small heat capacity. This means that parboiling can take place very quickly without consuming too much electrical power.
- the division of the resistance layer into areas and the different electrical surface load make it possible to adapt the heat given off by the individual areas to the requirements of cooking, which can be used to improve the heat output.
- the outer area of a round cooking surface is heated to a greater extent, which leads to better heat transfer in the case of commercially available cooking pots, which generally only rest on the outer ring of the hotplate.
- the resistance layer is preferably evaporated in vacuo. However, it is particularly favorable if it is printed using the screen printing method.
- the resistance consists of a so-called cermet layer, in which platinum, rhodium or another suitable metal in oxide form is mixed in powder form in a glass frit.
- cermet layer in which platinum, rhodium or another suitable metal in oxide form is mixed in powder form in a glass frit.
- one or more temperature sensors made of a substance with a negative or positive resistance coefficient can be applied in the same screen printing process. In both cases, simple application with good adhesion of the resistance layer to the hotplate body is achieved.
- the ceramic substrate can advantageously be colored. This makes it possible to give the hotplate an attractive appearance.
- the resistance layer can advantageously have a mechanical protective layer on its side opposite the substrate.
- the invention proposes that below the resistance layer, i.e. thermal insulation is arranged between the resistance layer and any floor panel that may be present.
- the electrical connection lines can advantageously be soldered onto the resistance layer or an additional silver plating. Brazing is particularly suitable for this. This is a particularly cheap, space-saving and inexpensive type of fastening, since no additional connection terminals are required at this point.
- the silver plating can also be produced in the manufacturing process of the resistance layer. It is also possible to apply a silver-palladium layer as a contact, also using the screen printing process, on which then e.g. a metal bracket made of nickel sheet is hard soldered. Electrical assembly by conventional resistance welding can then be carried out at this angle. It is also possible to vapor-coat a nickel layer as a contact on which a metal angle, e.g. is welded on by laser.
- strain relief of these connections is advantageously taken up by the downward leg of the rim.
- the invention further proposes that the downward leg of the overflow edge is provided with at least two bolts which are used to fasten the hotplate in the bowl with the aid of the fastening plate or of the bottom plate are provided.
- the attachment of the substrate to the overflow rim can also be carried out extremely easily, since, according to the invention, the heated plate is preferably glued tightly into the overflow rim with a ceramic adhesive. It is particularly advantageous when the coefficient of expansion of the overflow rim is equal to that of the heated plate.
- the areas of the resistance layer are divided into circular or circular ring sectors.
- a circular shape as it would have a normal hotplate, can be formed by eight circular sectors of equal size, one connecting line being connected in the middle of the circle and the other on the circumference of the circle.
- the regions of the resistance layer are formed in the form of circular or circular ring sectors, they alternately have incisions on both sides. These incisions reduce the cross-section in the surface direction, the regions of the resistance layer thus formed taking the form of a meander. It is preferably provided that two sectors are symmetrical to each other with respect to their dividing line.
- a hotplate with its overhang rim 12 is inserted into an opening in a hob 11.
- This overflow edge has a circumferential, approximately horizontal section 13, the outer edge of which is bent downwards.
- a sealing ring 15 is inserted between section 13 and section 14 of the hob 11.
- the overhang edge 12 has a shoulder 16 which is intended to receive the hotplate body 17.
- the overhang edge 12 On its side of the shoulder 16 facing the center point, the overhang edge 12 has a circumferential flat-cylindrical leg 18, to which three screw bolts 19 are fastened, distributed over the circumference. Only one of these three bolts can be seen in FIG. 1.
- a bottom plate 20 is arranged below the hotplate and has a number of openings corresponding to the number of screw bolts 19, through which the screw bolt 19 extends.
- a nut 21 and a washer 22 are screwed onto the screw bolt 19, with this screw connection pressing the base plate with its peripheral edge 23 against the underside of the hob 11. In this way, the overhang edge 12 and the base plate 20 are attached to the hob 11.
- the bottom plate 20 has on its top, i.e. H. on its side facing the hotplate, a relatively thick layer 26 of insulating material, which has a circumferential annular groove 29 for receiving the leg 18 of the rim 12.
- a resistance layer 27 is applied to the underside of the hotplate body 17, for example printed using a screen printing method.
- This resistance layer 27 is directly on the cook plate body 17 applied since it consists of electrically insulating material.
- a thin protective layer 28 is applied, which protects the resistance layer 27 from mechanical damage.
- Fig. 3 shows the view of the hotplate body 17 in Fig. From below.
- the rim 12 is not shown.
- the resistance layer 27 consists of a total of eight circular ring sectors 30. Each of these sectors 30 extends over an angle of approximately 45 °. If one looks at the two upper sectors in FIG. 3, it can clearly be seen that they are constructed symmetrically to the dividing line 31. Incisions 32, 33 and 34 are made in each sector, each extending along a concentric circular arc and giving each sector 30 a meandering appearance.
- a star-like silvering 35 with four beams is applied, the four beams 36 each engaging in a joint between two sectors 30.
- This silvering 35 connects the one wire, which is not shown for the sake of simplification, while the second wire engages from the outside the four silvering 37, which are also arranged in joints between two sectors.
- the specific surface load of the sectors 30 decreases from the outside inwards.
- the outer part of each sector 30, ie the area between the outer edge 38 of the sector and the first incision 32, may have a surface load of approximately 11.5 W / cm 2
- the area between the inner edge 39 of the sector 30 and the adjacent notch 34 has a load of about 8 W / cm 2 .
