Definitions
- the present invention relates to a sensor-controlled hob with a hob, in particular made of glass ceramic or glass, with at least one cooking zone, which can be heated by means of a heating element arranged below the hob is, as well as with one arranged below the hob plate and against it Underside directed in the area of a measuring spot limited in area Heat radiation sensor unit that is connected to a control unit Regulation of the heating power of the heating element.
- Such a hob is known from GB 2 072 334 A, wherein a parabolic reflector arrangement is provided below the hob.
- the reflector assembly collects one from the bottom of the bottom on the Stovetop and radiated pan heated by the heating element Heat radiation and conducts this via a connected optical connecting line to an infrared sensitive photodiode. The so detected Heat radiation is used as a signal to regulate the heating power of the heating element used.
- the object of the present invention is in a sensor-controlled hob according to the preamble of claim 1, the heating power control independent of the pot to ensure sufficient accuracy.
- the emissivity of the bottom of the Hob plate at least in the area of the measuring spot at least in the spectral measuring area the heat radiation sensor unit at least 60%, in particular more than 90%.
- the measuring accuracy according to the invention is at least sufficient to Carry out frying or frying with satisfactory cooking results can. It is to increase the accuracy of the sensor-controlled system expedient, pots or pans with as flat as possible and thus to be used over a large area on the top of the hob.
- a measuring spot with suitable transmission and Emission properties can be achieved if the hob is on the underside of the Area of the measuring spot with a dark, in particular black, emission layer is provided.
- the transmission and emission values are then on the one hand regardless of production variation and on the other hand over the life of the Hob is essentially constant despite its aging. Furthermore, the Values are then independent of the properties of the material of the hob plate or regardless of manufacturer or color.
- a suitable size of the measuring spot is about 1 to 4 cm 2 . This ensures that, on the one hand, the measuring spot is not too large, which would affect a uniform cooking result in the pan or the pot. On the other hand, the measuring spot must not be too small so that the influence of the heat radiation from the base of the pot on the glass ceramic remains large enough. If the surface area of the measuring spot is too small, despite the low thermal conductivity of, for example, glass or glass ceramic, its sensed temperature is essentially exclusively dependent on the temperature of the glass ceramic in the vicinity of the measuring spot.
- the aim of the hob according to the invention is to infer the temperature of the heated cooking vessel placed on the hob and to regulate it.
- the heat radiation sensor unit a special filter
- the spectral pass band essentially is between about 4 and 8 ⁇ m. In this area is both the value of the transmittance as well as the average reflectance of the material the hob plate with typical glass ceramic hob plates is sufficiently low. This results in a high emissivity in this wavelength range Underside of the cooktop and associated high sensitivity and accuracy.
- the spectral passband can typically are also between about 10 to 20 microns. The value is also in this range the transmittance for typical glass ceramic material is about 0% and that of The degree of reflection is significantly lower than in the wavelength ranges neighboring on both sides.
- the choice of a suitable spectral filter is particularly of its price depends on and on the achievable in the respective wavelength range Sensitivity or measuring and control accuracy of the sensor-controlled Cooktop.
- a measuring shaft is arranged in which the heat radiation sensor unit is directed to the measuring spot of the hob plate. This measure ensures that the temperature influence of the measuring spot by the heat radiation radiating heating element greatly reduced or excluded is. It is particularly advantageous if the measuring shaft is as close as possible to the Underside of the cooktop is present, as well as if the radiation channel in the measuring shaft is insulated as well as possible from the space outside the measuring shaft.
- a computing unit calculates the Hob from the signal of the heat radiation sensor unit and in one Storage unit stored characteristics of the hob the temperature of the floor of a heated cooking vessel placed on the hob plate and indicates this the control unit for regulating the heating output. From laboratory tests Findings can be typical indicators for the relationship of the measurement signal the sensor unit to the prevailing pot bottom temperature become. These are then stored in the storage unit and are used during the cooking process suitably linked with the measurement signal of the heat radiation sensor unit. The ground temperature derived from this then in turn becomes control signals determined for the heating power of the corresponding heating element.
- the precision The system can be used especially with large cooking vessels such as for example, frying pans can be increased if at least two heat radiation sensor units be used. It is also useful to have a to realize known pot detection unit or the measurement signals of the To use heat radiation sensor unit for pot detection.
- a hob 1 has a hob plate 3 made of glass ceramic material, on the Heated zones are marked on the top with the aid of a decorative print (FIG. 1). These zones are in each case corresponding to themselves below the hob plate 3 known metallic radiator pots 5 assigned. These are by themselves Known tools, not shown, pressed onto the underside of the hob plate 3.
- the radiator pot 5 has a radiator insulation on the bottom and on the circumference 7 on. In this or on this is a radiation heating conductor known per se 9 held by the heat radiation when dining with electrical current in particular in the direction of the underside of the hob plate 3. Above the radiator pot 5 or the radiant heater 9 a frying pan 11 placed on the top of the hob 3.
- the emissivity ⁇ of the bottom the pot base 11 is typically about 10 to in stainless steel pots 20% and typically around 80 for a black enamelled pan base up to 90%.
- a tubular one Measuring shaft 15 provided, the upper end face close to the bottom of the Hob 3 is present.
- the diameter of the measuring shaft is approximately 1 to 2 cm.
- the measuring shaft 15 is with suitable insulation means for thermal insulation compared to the measuring arrangement described below in particular the heating conductor 9 provided. Furthermore, the measuring shaft 15 has on its inner circumferential side to increase the sensitivity of the measuring arrangement described below a reflection layer 17.
- the limited by the measuring shaft 15 Circular area on the underside of the hob plate 3 serves as a measuring spot 18 of the measuring arrangement.
- a heat radiation-sensitive infrared sensor 19 is arranged at the end of the measuring shaft opposite the measuring spot 18 15.
- This Upstream is an infrared optic 21 with a spectral filter, the spectral Passband is between about 5 and 8 microns.
- Through an aperture 23 in Bottom of the measuring shaft 15 is the infrared sensor 19 on the measuring spot 18 Hob 3 directed.
- a suitable sensor window 25 is set.
- the infrared sensor 19 For cooling the infrared sensor 19 this sits in a cooling duct connection of the bottom of the radiator pot 5, to which cooling air (cooling air arrows) is supplied if necessary. Furthermore, between the radiator pot 5 and the radiator insulation 7, a cooling channel 27 is provided. This ensures that the permissible continuous operating temperature of the infrared sensor 19 of about 100 to 120 ° C is not exceeded (Fig. 1).
- the transmittance of the glass ceramic cooktop has the through Spectral filters define the spectral measuring range of the infrared sensor 19 of approximately 5 2 to 8 ⁇ m according to FIG. 2 a transmittance ⁇ of approximately 0%.
- Spectral filters define the spectral measuring range of the infrared sensor 19 of approximately 5 2 to 8 ⁇ m according to FIG. 2 a transmittance ⁇ of approximately 0%.
- the value of the transmittance ⁇ is ideally about 0% and that of the emissivity ⁇ is approximately 100% (FIG. 5).
- the heating conductor 9 moves according to FIG Measuring shaft 15 essentially on all sides. Whether the measuring shaft 15 on the edge of the radiator pot 5 or rather arranged in its central area depends of the respective circumstances. For example, it can be used of two measuring shafts 15 in a radiator pot 5 for reasons of accuracy despite, for example, an uneven temperature distribution in the soil the pan may be advantageous if the two measuring shafts 15 each in the edge area the radiator pot 5 are arranged (Fig. 3).
- both the Radiant heating conductor 9 and the cooktop 3 heat radiation to the bottom of the pot 11.
- the hob plate touches heat conduction between the two instead. The same applies in the direction parallel to the hob 3 within this.
- the infrared sensor 19 is through the Measuring shaft 15 shielded from the heat radiation of the radiant heater 9. It is also characterized by the properties of the material of the hob plate the heat radiation of the cooking vessel 11 largely shielded.
- a computing unit 41 determines the hob from the measured value S of the infrared sensor 19 and from in a storage unit 43 characteristics of the arrangement stored in the cooktop 1 have a corresponding output signal, from the one control unit 45 of the hob 1 a heating power signal P for the radiant heating conductor 9 is derived (FIG. 4). This makes it possible; that for example an input element known per se by an operator predetermined cooking temperature of 180 ° C by the control unit 45 is automatically adjusted.
