Definitions
- the invention relates to a radiant heating element for heating glass ceramic plates in cooking appliances, with at least two areas with clocking power-controlled electrical heating resistors and a temperature limiter with a temperature sensor extending over both areas.
- the object of the invention is to provide a heating element which, despite increased performance and good manufacturability, permits uniform heat distribution when both heating zones are switched on.
- the invention achieves this object in that a series heating resistor arranged in the outer region of the heating element can be connected in series to a central heating resistor and can be switched off in a switching state of the temperature limiter.
- a high output with a high specific heating surface load can be installed in the central heating resistor in the central zone, while a uniform power distribution is achieved by the series heating resistor over the entire heating surface of the heating element.
- the ballast resistor can be arranged in the outer region or the heating zone in addition to a further heating resistor which can be connected in parallel with the central heating resistor, for example.
- the power distribution can be set as desired.
- the specific heating surface load of the central zone can be reduced due to the series heating resistance.
- This embodiment is also suitable for heating elements which deliberately have two differently sized or differently designed heating zones which are switched on differently depending on the size or shape of the pot.
- the ballast heating resistor can be connected upstream to normal power in order to reduce an increased switch-on power provided in the central heating resistor. If the pre-heating resistor closely surrounds a central heating zone containing the other heating resistor, the result is a total cooking surface which is often not significantly larger than that occupied by the central heating resistor.
- the total cooking surface switched on with a series heating resistor has a lower overall output than the central zone alone, especially when switched on.
- the outer area can be integrated into an overall winding to the extent that it takes up the outer of the spirally laid turns of both heating zones.
- DE-A-30 07 037 also shows, in the case of heating elements with two areas, in accordance with the heat effect on the temperature sensor of a temperature limiter which is limited to only a certain area in a heating zone, to equip it with switches of different response temperature in order to switch off at a comparable surface temperature of the glass ceramic plate to reach. It is then necessary to lay four supply lines between the control unit and the heating element and to design the switch for the second heating zone as a double switch. If, in a particularly preferred exemplary embodiment of the invention, a temperature limiter is provided with two contacts of different response temperature, of which the one with a low response temperature is designed as a changeover contact, this problem is solved.
- the changeover switch switches the heating resistor, which can also be switched on individually, when the lower adjusted response temperature is reached from a current branch upstream of the switch to a current branch downstream of the switch, so that it is switched off on its own, but when both heaters are switched on zones is switched on again with its power possibly reduced by the series resistor.
- This circuit only requires three hotplate feed lines and a simple switch for connecting the second heating zone.
- FIG. 1 and 2 are schematic top views and circuit diagrams of a heating element and its control.
- a radiant heating element 11 is shown for a glass ceramic hotplate of a cooker. It contains on an insulating support 12 heating resistors 13, 14, 15, which consist of wire coils, which are attached in the form of arcs, spirals or double spirals on the surface of the insulating support.
- heating zones 16, 17, are arranged in two areas, hereinafter referred to as heating zones 16, 17, the central heating zone 16 containing the heating resistor 13 and being surrounded by an annular heating zone 17 with a substantially larger total area, in which a main heating resistor 14 in the form of an annular loop with four Coils running parallel to one another, but the heating resistor 15 is arranged in the form of a simple, curved loop between the two outer strands over a sector of, for example, 60 ° and supplements the main heating resistor 14 on the four strands there.
- a rod-shaped temperature sensor 18 of a temperature limiter 19 protrudes diametrically over both heating zones 16, 17 and protects the glass ceramic plate from harmful overheating by switching off the heating resistors.
- the temperature limiter contains two switching contacts 20, 21 which are adjusted to different response points and of which the contact 21 is a changeover contact.
- a clocking power control device 22 is used to control the power. It contains a bimetal 23 which is heated by a control heating resistor 24 and which acts on a switch 25, the power which is thereby clocked in different relative operating times being adjustable via an adjusting knob 26.
- the outer heating zone 17 can be activated by an additional switch 27.
- the power supply to the heating element 11 takes place via the switch 25 and the contact 20 of the temperature limiter 19 adjusted to a higher temperature.
- the heating resistors 14 and 13 are connected to this branch 28.
- the other end of the middle heating resistor 13 runs to the other switching contact 21 of the temperature limiter and can be branched there to two connections which are connected on the one hand to the other network pole 29 and on the other hand to a feed line 30 to the series heating resistor 15.
- the other ends of the heating resistors 14, 15 are put together at the switch 27.
- the function of the heating element is as follows (Fig. 1): When the switch 27 is open, only the central heating zone 16 is operated, for example if only a small pot is to be heated. When the power control device is switched on via the setting knob 26, the switch 25 is closed and the middle heating zone is operated at its full power, for example approx Can be 50% of the total power of the heating element. This results in a relatively quick heating of the small cooking vessel.
- the middle heating zone 16 heats only the middle part of the temperature sensor 18 to full temperature, so that the resulting expansion of the temperature sensor is less than when the temperature sensor is fully loaded. Since the changeover contact is adjusted to a lower response point, the heating resistor 13 nevertheless switches off at the correct limiting temperature. The switch contact 21 then switches to the contact 31.
- the outer heating zone 17 is switched on via the additional switch 27, then with a previously cold heating element, i. H. not yet responding contact 21, the undiminished power of the heating resistor 13, for example 900 watts, and the power of the heating resistor 14 (e.g. 1400 watts) switched on, so that a high total power for boiling is switched on. Since the entire temperature sensor length is now heated, the contact 21 is switched over much earlier, i.e. at a temperature significantly below the limit temperature. By switching to contact 31, heating resistor 15 is now connected in series to heating resistor 13, so that the power of heating resistor 13 is considerably reduced (for example to 650 watts), while the outer heating zone has a relatively small amount of power due to the pre-heating resistor 15 will be added.
- the specific heating surface loads can be adapted to the circumstances by appropriately dimensioning the heating resistors. In any case, it is possible to achieve a uniform specific heating surface load over the entire surface, or even to choose a lower one in the central area.
- the contact 20 switches off the total power and switches it on again when the temperature drops.
- the arrangement of the heating resistors can be different.
- the arrangement of the switch-on heating resistor 15 which is limited to a ring segment, this could also be arranged, for example, as a winding that runs around the entire heating element.
- the advantage remains that the ballast heating resistor not only reduces the performance of the other heating zone, but also that Switch-on heating zone 17 receives additional power from the ballast heating resistor.
- the arrangement can also be useful with a configuration other than circularly concentric, for example with a rectangular heating element with a central round hotplate and additional heating zones attached on both sides, the elongated rectangular cooking surfaces being mostly used for heating and therefore a uniform power distribution is particularly important.
- the temperature limiter described has the advantage that the switch options described are possible with only one additional switch 27 as a result of the changeover switch 21, since when the lower response temperature is reached, the changeover switch switches the heating resistor 13, which was previously only switched on, in parallel with the heating resistor 14, with the ballast heating resistor itself 15 is connected upstream.
- FIG. 2 shows a heating element in which there are two heating zones 16a, 17a, but which are not as clearly separated from one another as in FIG. 1. They are not intended, as in FIG. 1, to heat pots of different sizes , but are assigned to a cooktop of a uniform size. Accordingly, the bowl-shaped insulating body 35, in which the heating resistors 13a, 15a are arranged, also has no internal subdivisions, but only an edge 36 surrounding the common cooking area formed from the two heating zones, which lies against the underside of the glass ceramic plate.
- the arrangement of the heating resistors is such that the inner heating resistor 13a takes up most of the area, while the outer heating resistor 15a is practically limited to the outer winding .
- both heating elements are continuous in the form of a double spiral, i. H. a spiral with two parallel turns in the reverse turns in the middle of the heating element.
- the outer heating resistor extends between a connection 37 and a tap 38, which is formed by an inserted connecting pin between the heating resistors 13a, 15a, while the central main heating resistor 13a is connected between a connection 39 on the inside of the outer double turn and the tap 38 .
- a temperature limiter 19a is provided, the rod temperature sensor 18a of which projects somewhat eccentrically over both heating zones 16a, 17a.
- the temperature limiter 19a has only a simple switching contact, which is opened when the response temperature is reached.
- the heating resistor 13a alone is switched on, which has a comparatively large output. It corresponds to a parboiling rate, i.e. a higher output than the heating element should have in the permanent state.
- the wire from which the heating coil 13a is made can therefore be relatively thick and is therefore easy to lay and thermally and mechanically durable.
- This power is clocked according to the response of the power control device 23, 24, 25 according to the set power value.
- the switch 27 is opened, the previously short-circuited heating resistor 15a is connected in series in front of the heating resistor 13a, so that both heating resistors together now have a lower output than the heating resistor 13a alone. In this position, both heating zones 16a, 17a are switched on and there is a more evenly distributed, but lower power which is used for continued cooking.
- the strong power concentration in the heating area is also less critical, since in this area the food is still cold and does not tend to boil or partially burn, while in the continued cooking area, if this becomes critical, the comparatively lower power is available.
- the service life of the heating elements is also surprisingly good. Despite the heavy load on the heating resistor 13a during the boil-up phase, this does not reduce the service life, because this time is usually very short.
- the switch 27 is preferably operated manually, but could also be operated thermally or by a timer.
