Definitions
- the invention relates to a ceramic hob with a glass ceramic plate, the separated on its underside via an insulating layer heating elements for direct Heating carries, wherein the cooking zone at least in an inner and an outer Sub-zone is divided, which carry sub-zone-specific heating elements, which by means of a control in dependence on the sub-zones associated Temperature sensors detected temperature values switching and / or in their performance are controllable.
- Such a ceramic cooktop is known from DE 41 30 337 A1.
- the sub-zones each have a meandering applied Edelleiter on, in the vicinity of a same guided sensor track to Temperature detection runs.
- the heating conductors and the sensor tracks on one, the entire cooking zone covering insulation layer applied.
- a ceramic hob has the same Disadvantages arise when the heating elements radiate to the center of the Cooking zone are aligned and extend over sector-shaped subzones.
- the construction and application of the heating elements is difficult even then if concentric, circular on the bottom of the glass ceramic plate Printed conductors are applied, extending almost 360 ° over the circumference of the subzones extend. Between two tracks, the glass ceramic plate forms a Parallel connection of many temperature-dependent differential resistors, such as DE 40 22 846 A1 shows.
- the variety of resistors can also be due to many strip-shaped tracks realized, which are connected in parallel with their ends, like the EP 0 315 079 B1 (DE 38 84 569 T2). In this training of the hob However, no individually switchable and controllable subzones are formed.
- the manufacturing technology easy to apply and free areas in which temperature sensors can be applied directly to the bottom of the glass ceramic plate.
- the Heating elements extend over the largest surface portion of the associated Subzones and ensure optimal and uniform heating of these Partial areas, which leads to a high efficiency of the hob, there also the temperatures of the sections in a simple manner independently recorded and used for switching and controlling the heating power can.
- the temperature sensors can also be used on thin insulation layers be applied, the glass ceramic plate outside the heating elements cover. Are the temperature sensors housed in insulating covers, then they can also be applied to the heating elements.
- connection sector can be kept narrow according to one embodiment be that the connectors in the terminal sector over the outer sub-zone are led out. Outside the cooking zone remains for the connection contacts and the connecting cables more space.
- the temperature of the inner subzone of the cooking zone is monitored by that the temperature sensor in the center of the cooking zone as a bar sensor or Point sensor is formed and with its connection via the connection sector is led beyond the cooking zone.
- the conductor tracks consist of NiCr, NiAl or Cermets alloys and in the thermal Syringes are applied, while as sheet heaters heating foils, NiCr, NiAl or cermets layers are used on the insulating sublayers are applied.
- the printed conductors and the surface heating elements can also be used as silver-containing Webs or layers are applied by screen printing. In addition, you can they are applied with carbon paste.
- FIG. 1 In the embodiment of FIG. 1 is a glass ceramic plate 10 on the Bottom view 11 seen. A round cooking zone is in a known manner marked on the top. On the underside of the glass ceramic plate 10 are a plurality of circular arc-shaped interconnects 15 on the same running coextensive insulating sub-layers 12 applied. These interconnects 15 extend over nearly 360 ° of the circumference of the cooking zone and leave only a narrow connection sector 16 free, extending to the center of the cooking zone extends.
- the insulating sub-layers 12 have a high electrical Insulation resistance, i. a high dielectric strength. They are as thin Insulation conductor formed with a small heat transfer resistance.
- connection sector 16 In the area of the connection sector 16, the conductor tracks 15 are connected by means of connecting pieces 17 connected in series, so that a heating coil with alternating direction of rotation of the turns arises.
- a terminal a0 to the beginning A is the innermost one Conductor 15 led.
- a terminal a1 is in the terminal sector 16 with a Connecting piece 17 is connected, so that the heating coil in a heating element H1 and a heating element H2 is divided.
- These heating elements H1 and H2 are then an inner sub-zone Wi and an outer sub-zone Wa assigned.
- the terminal a2 is connected to the end E of the outermost conductor 15, so that the two heating elements H1 and H2 can be controlled independently of each other and in the heating power are adjustable.
- N switched controller ST provided at the terminals a0, a1 and a2 are connected.
- S1, S2, S3 and S4 that of the temperature sensors So, S1, S2, S3 and S4 detected temperatures of the regions of the glass ceramic plate 10 supplied.
- the temperature sensor So is in the center of the inner Sub-zone Wi, i.
- the temperature sensor is metallic, it is outside the heating elements a thin insulation layer to avoid short circuits.
- the beginning A, the end E and the tap of the heating coil lead to connection contacts, which are outside the round cooking zone and there enough Find space.
- the heating cables ho, hi and h2 from the control ST can therefore be easily connected to the terminals a0, a1 and a2.
- the terminal sector 16 can be made narrow, so that the circular arc-shaped, concentrically arranged conductor tracks 15 can extend over a maximum proportion of the circumference and Cover the cooking zone over a large area. This brings a uniform heating the subzones Wi and Wa with good efficiency.
- the insulation sublayers 12 can be arranged in the same arrangement with the same area be applied to the bottom 11 of the glass ceramic plate 10, so that outside the tracks 15, the bottom 11 of the glass ceramic plate 10 for the direct connection to the temperature sensors So, S1, S2, S3 and S4 accessible is and that the temperature sensors without being affected by a Insulation layer 12 can make the temperature measurement. As mentioned, These areas of the bottom of the glass ceramic plate 10 also with Thinner insulation layers may be occupied when metallic temperature sensors are used.
- an annular heating foil 15i forms the heating element H1 associated with the inner sub-zone Wi and the annular part Bankfolie 15a the outer sub-zone Wa.
- the terminal contacts a0, a1 and a2 in Terminal sector 16 switch the heating elements H1 and H2 in the opposite direction Turning in a row.
- Between the two heating foils 15i and 15a creates an insulation-free space 21 for direct attachment of Temperature sensors S1, S2, S3 and S4 on the underside 11 of the glass ceramic plate 10.
- the heating foil 15i has a central recess 20 in which a arranged as a rod sensor or point sensor temperature sensor So arranged is and with its connection over the connection sector 1 6 like the connection contacts a0, a1 and a2 are led out of the cooking zone and as in the Embodiment of FIG. 1 with a controller ST are in communication.
- the two subzones Wi and Wa of the cooking zone can therefore be dependent switched by associated temperatures and / or regulated in the heating power become.
- the heating foils 15i and 15a the vast majority of the cooking zone, so that the subzones Wi and Wa can be heated evenly and this depending on the associated temperature sensors So or S1, S2, S3 and S4 detected temperatures.
- precisely the temperature sensors S1 to S4 ensure that for the outer partial zone Wa temperature differences over the circumference of the cooking zone edge recorded and taken into account.
- the terminal contact a0 connects on one side of the terminal sector 16 the two heating foils 15i and 15a as a tap for the subdivision of Heating element in the partial heating elements H1 and H2.
- the structure of the cooking zone with the two heating foils 15i and 1 5a is simple and easy to apply.
- the solicitn2020elemetne also in a similar manner how the printed conductors 15 of FIG. 1 are applied, for which purpose NiCr, NiAl alloys, Cermets, silver coatings or carbon paste coatings be used.
