Definitions
- the invention relates to a method for hob control, with a hob plate, in particular made of glass ceramic, with at least one cooking zone, which by means of an arranged in the installed position of the hob below the hob plate induction
- Heating device is heated, with an electrical control unit with processing unit and memory and with the cooking plate below in the region of a limited measuring spot arranged heat sensor units, with the first heat sensor unit essentially in the cooking zone alone of the hob plate and with the second and third heat sensor unit is detected substantially in the cooking zone of the hob plate and a turned-off cookware downgoing outgoing heat flow, as well as with a light source for performing a reflectance measurement via at least one thermal sensor to determine the emissivity ⁇ K ⁇ chgeschir r of the cooking pot one on the hob plate off the cookware and a hob to carry out the process.
- Such a method is known for example from DE 10 2004 002 058 B3.
- the known method controls a cooking process in a hob, with a hob plate, in particular glass ceramic, which has perpendicular to their Hauptausdehnungslegien limited by a flat top and bottom material thickness s, with at least one cooking zone, by means of a in the installation position of the hob below the cooktop panel arranged heating device is heated, with an electrical control for controlling the heating power of the heater and arranged below the cooktop plate heat sensor units.
- the known method proposes that with the first heat sensor unit essentially one in the region of the cooking zone alone of the hob plate and with the second and third heat sensor unit substantially a plate in the region of the cooking zone of the hob and a cookware placed on the bottom outgoing heat flow is detected.
- the heat sensor units are arranged on the underside of the hob plate in the region of a limited measuring spot, which is limited to the environment, for example by a measuring shaft or waveguide.
- the cookware bottom temperature T K ochgeschirr is determined and evaluated in the electrical control device with processing unit and memory for controlling or regulating the heating power of the heater.
- the known method it is not absolutely necessary for this purpose to know the emissivity of the cooking utensil ⁇ Och gesc h i rr .
- consideration of the emissivity of the cookware tray would result in a more accurate measurement of the cookware tray temperature Tis ch g eschi rr .
- DE 10 2004 002 058 B3 it is therefore proposed to carry out a reflection measurement in order to determine ⁇ K ⁇ ch g esch i rr .
- the invention thus presents the problem of providing a method for hob control in which the cookware temperature, taking into account the influence of the emissivity of the cookware and the transmittance of the hob plate is determined as accurately as possible and evaluated for the hob control in terms of controlling the power of the induction heating.
- the invention also raises the problem of providing a hob for carrying out the method according to the invention.
- the achievable with the present invention consist in particular in the improved accuracy of the control of a cooking process in a hob. This is achieved by an improved accuracy of determining the actually available to the cooking utensil bottom, and thus the cooking utensil temperature T cooking g esch i rr considering the influence of the emissivity of the cooking utensil, as well as the changed by contamination of the cooktop panel transmission coefficient.
- the emissivity of the cookware for carrying out the method according to the invention is preferably detected metrologically via the second heat sensor unit by means of a reflection measurement of the light beam emanating from a light source and directed against the cookware bottom.
- It is also possible to determine the emissivity of the cookware or cookware tray ⁇ och dish set and thereby to a usual mean, for example ⁇ O chgeschirr 0.5, set and store as a memory value in the controller.
- the transmission coefficient of the hob plate is known as a value and stored in the controller as a memory value.
- the influence of a possibly brought about by contamination of the hob plate variation of the transmission coefficient is ge by the above described reflection measurement and determination of the emissivity of the cooking utensil and the cooking pot bottom cooking sch e i rr also considered.
- the cookware bottom temperature T K ⁇ ch esch i rr is determined from the ratio of the two output signals of the second and third heat sensor units and a correction value from the output signal of the first heat sensor unit.
- the heat sensor units can be selected according to type, arrangement and measuring range within wide suitable limits. Therefore, it is possible that with the first heat sensor unit, for example, only the part of the heat flow emanating from the cooktop plate by means of heat conduction, for example by means of a touch temperature sensor, is detected.
- the heat sensor units in particular the second and third heat sensor unit, are designed as a pyrometer. It when the second and third heat sensor unit are combined as a unit to a single ratio pyrometer is particularly advantageous.
- a high measuring accuracy is achieved in the method according to the invention in that the hob plate is heated in the region of the measuring spot by means of the additional heater and by the temperature measured via the first heat sensor unit T S ⁇ ⁇ is adjustable. In this way, it is ensured that the temperature of the hob plate in the region of the measuring spot is maintained approximately at T S ⁇ ⁇ .
- the value for Ts O ⁇ corresponds to an assumed value for the temperature of the cookware or the cooking zone, which should be achieved after the heating phase.
- the measuring spot is preferably provided in the center of the cooking zone. A decentralized arrangement of the measuring corner, eg in the edge area of the cooking zone, is also possible.
- the auxiliary heater for direct heating of the hob plate is arranged in the region of the measuring spot in heat-conducting contact with the underside of the hob.
- the heat transfer from the auxiliary heater to the hob plate is improved, so that the heating phase is not extended by heating the Kochfeidpiatte in the range of Meßfiecks on T S ⁇ ⁇ in an undesirable manner.
- a waveguide in particular a waveguide, delimits the beam path between the hob plate and the heat sensor units designed as a pyrometer to the environment. In this way, on the one hand, it is ensured that the heat radiation radiated from the hob plate and the cookware passes largely loss-free to the heat sensor units. On the other hand, interference radiation from the environment is largely shielded, so that the measurement results are not affected in an undesirable manner.
- Another advantageous alternative to the aforementioned embodiment further provides that a reflective half shell, in particular Ulbrichtkugel, the beam path between the hob plate and designed as a pyrometer heat sensor units limited to the environment, wherein the reflective half-shell has openings for the aforementioned heat sensor units.
- the multiple reflection of the heat radiation radiated from the cooking plate and the cookware bottom in the direction of the aforementioned heat sensor units is further increased, so that the input signals of the heat sensor units are amplified, resulting in an improved signal quality.
