Definitions

  • the invention relates to an electronic control for a cooking appliance with at least one heating device and a method for controlling a cooking appliance in a corresponding manner.
  • electromechanical control devices or energy controllers such as from the DE 19833983 A1
  • a clocking operation is performed with either full or no power.
  • the energy ultimately supplied to the heater is set or controlled permanently.
  • the switching of the controller is carried out by a snap-action switch, is influenced by a bimetallic release arm, as is known in the art.
  • parboiling function in which the control unit can be set or switched on.
  • this parboiling function is a particularly high power level of the heating power, also called cooking stage, applied for a certain cooking time to the heater, resulting in the so-called Ankoch briefly. This serves to bring the heater and a cooking vessel placed thereon as quickly as possible to high temperature, for example to bring a larger amount of water to a boil.
  • the heater is no longer supplied with power for some time. This is due to the fact that the power stage after the cooking stage is usually considerably lower and the bimetal tripping arm therefore only moves back a considerable or larger distance before it can again cause it to be switched on by means of the snap-action switch. This time can be up to five minutes, which has proven to be very advantageous in practice to keep the most quickly heated cooking vessel at a desired temperature.
  • the invention has for its object to provide an aforementioned control and a corresponding method for controlling a cooking appliance, with which problems of the prior art can be eliminated and in particular an optimized or energy-saving cooking process can be achieved.
  • the electronic control has operating elements, advantageously touch switches or the like, as well as a controller and at least one power switch for the heating device.
  • a circuit breaker is advantageously a named relay, but may also be a semiconductor component.
  • the controller is designed to carry out a so-called boost function on the heating device with a high power level of the heating power as a boosting step. This warm-up or warm-up step is carried out for a certain warm-up time and forms the known boil-up.
  • the controller is adapted to switch off the heater after setting a power level lower than the cooking level after the power stroke for a certain predetermined pause time, and then turn it on again after the pause time has elapsed.
  • This break time is or lasts longer, the lower the new power level is in comparison to the previous power level or to the cooking level.
  • the break time is determined so to speak variable. This ensures that the controller or the electronic control after the butting of the heater for a certain time no longer supplies power or leaves it off.
  • the said pause time can be considerably longer than a usual off-time when clocking operation of the heater at the new power level, for example, something three times as long.
  • This can be used in a cooking process in which, for example, water for noodles are first brought to a boil and then only slightly boiling, the heat surplus can be used to maintain this boiling, so that only after a long time or just this break time again Heating power is supplied, and that at the now lower new power level.
  • an advantageous function can be achieved in a new way, which is practicable and, above all, can even save energy.
  • the length or duration of the pause time does not depend on the amount of the butt joint or on the difference of the new power level to that before, but of the cooking time, ie the length or duration of the Ankoch devises.
  • This dependency can be such that a long warm-up period results in a long pause time with power interruption and a short warm-up time resulting in a short pause time. It is therefore possible to make the break time dependent either on the height of the cooking stage or particularly advantageously on the length of the cooking time.
  • the break time depends on the properties of the buttock. Also in the dependence on the cooking time is considered that after the expiry of the Ankoch tenues probably more heat in the system or in the cooking vessel as necessary and desired for the fort cooking or the further operation.
  • the cooking stage is the highest power level for the heater. So it's a fixed performance level. Furthermore, it can be provided that the cooking time is fixed, for example, three to ten minutes, advantageously four to seven or just over five minutes. Since in cooking appliances such as hobs, the heaters are usually different sizes, the size of the heater can play a role. Since the size of the heater is influenced by the size or volume of an attached cooking vessel or the volume of cooking material usually contained therein, and a surface of the heater with the second order of the diameter, the volume of the cooking material but with the third order of the diameter increases, the duration of the cooking time should be longer for larger heaters than for smaller ones.
  • the break time contained in the control with the power interruption during downshift is designed so that in the case of switching back to the lowest power level about twice to four times, more preferably about three times as long as when switching back to the second highest performance level.
  • the pause time can therefore be at the lowest power level about the above five minutes, at an average power level about three minutes and at the second highest power level just over a minute, for example about one and a half minutes. This still achieves a significantly longer pause time than currently used controls in which the heater is usually supplied again at the latest after 45 seconds or one minute, even when returning to the lowest power level, power again or it is turned on again.
  • the controller or the controller contained therein and the control method are advantageously designed so that the power interruption according to the invention for a certain pause time on the heater also takes place when the heater is not switched directly after the cooking stage to a lower power level, but is turned off. If it is then switched on again soon, then the controller or the controller has memorized the previous state and then necessarily provides the corresponding pause time adapted to the new power level.
  • the controller or the controller remember this previous state even when the entire cooking appliance is turned off, at least for a short time and then turned on again and especially the corresponding heater is turned on again.
  • operating sequences can also be detected in which switching back to a very low power level does not take place by stepwise reducing the power level of operating elements, but by switching off the heating or cooking area or even switching off the entire cooking appliance.
  • operators tend to perform this turn-off and then just turn on the heater again, starting with the lowest power level or, if desired, with exactly that one.
  • the pause time is calculated and just kept by not turning on the heater.
  • Fig. 1 is a plan view of a functionally illustrated hob 11 included, which has in its front region a controller 13 with a plurality of controls 17, for example, known touch switch, so called touch control.
  • the hob 11 has four distributed cooking zones 15a to 15d.
  • the Control 13 to a controller 18, which contains the control functions, so to speak.
  • the controller 13 is connected to a switching device 20 for supplying power to the cooking zones 15.
  • each of the cooking zones 15 can be switched on and off via the switching device 20 in any desired manner within certain functional or program-technical functions.
  • the controller 13 with the controller 18 via the switching device 20 sets the corresponding on times and off times at a cooking position 15 for a cycle operation.
  • Fig. 2 is shown in the diagram both for the temperature of water in a saucepan, which has been placed on one of the cooking zones 15, as well as the power P over the time t, the respective time course. It is shown in dashed line the one in known or conventional electronic controls with separately controlled switches and solidly the one according to the invention.
  • a hotplate is turned on with a raised saucepan containing water, with the setting of a boil with the highest heat setting. This boil then takes a little over 5 1 ⁇ 2 minutes until the water temperature is above 80 ° C. This means that for this particular hotplate in the controller 13 and in the controller 18, a correspondingly long Ankochmen is programmed.
  • the controller 13 switches either automatically, because the predetermined end of the Ankoch devises is reached, or by an operator controlled down to a lower cooking level, for example via the intermediate cooking stages to the cooking level 4. This means that then at a time interval of a little less than a minute, the cooking is turned on or clocked for a short time. This clocking actually starts right after the end of the push, as there is the first short on-time just one minute after the end of the push.
  • heat should not be supplied again so quickly after the end of the Ankoch tenues, especially when the cooking should be done with the relatively low cooking level 4. This clocking then proceeds evenly with short on-times at a time interval of a little less than a minute, as can be seen in the diagram.
  • the solid curve shows that after the end of the Ankoch devises after about 5 1 ⁇ 2 minutes once for about 3 1 ⁇ 2 minutes, no power is given to the hotplate or it remains off. Only then does the cooking area be switched on again for a short time each time, the time interval initially being approximately 21 ⁇ 2 minutes and then, after a relatively long period of time, similar to the previously described known method, at intervals of approximately one minute. Times come.
