Definitions

  • the invention relates to an oven according to the preamble of claim 1.
  • a known oven In a known oven (DE-OS 27 57 059), the oven is heated during a heating phase with the full installed heating power, after which a switchover to an on-heating phase with a lower heating power takes place automatically before the selected target oven temperature is reached.
  • all heating phases are displayed to the user in accordance with the control cycle of the temperature controller in that a display element, e.g. an indicator light is activated, which goes out when the heating is switched off.
  • the present invention has for its object to improve an oven of the type mentioned in the preamble of claim 1 so that means are provided by which the user is signaled in the shortest possible time after switching on the oven, the heating state. In addition, it should be possible to shorten the actual heating-up time.
  • the end of the heating-up time is only displayed when the oven heating is switched off, and thus at an oven temperature that is significantly above the selected target temperature (settling of the temperature profile)
  • the e.g. Optical display when the target temperature is reached i.e. while the heating is still running.
  • the user can start cooking the food, e.g. Place the cake in the preheated oven, which not least also saves energy.
  • a further energy saving results from the fact that when the target temperature is at least approached, not only is the end of the heating-up phase signaled, for example by a signal lamp being extinguished, but at the same time the high heating-up power is reduced or switched off and the oven is operated with only one reduced continued heating output is operated.
  • a special partial heating output is provided for rapid heating, which can be optionally switched on for each heating mode.
  • the diagram according to Fig. 1 shows the time-temperature curve during the heating of the oven not shown or its oven muffle lockable by a door and during a subsequent heating phase.
  • the curve K1 shows the curve for a conventional oven and you can see that when heating with the maximum heating power installed in the oven at a preselected target temperature or oven temperature T1 of e.g. 200 ° C, the oven temperature actually measured initially overshoots the target temperature T1 and the oven heating is only switched off at a significantly higher overshoot temperature T2 at a point in time t3 and then, with reduced heating power in the continued heating phase after t3, the temperature curve is leveled out around the target temperature T1 . At time t3 this goes out e.g.
  • Display element designed as an oven lamp which signals to the user that the oven is now used to insert food, e.g. of a cake has a suitable target temperature, i.e. the heating process has ended.
  • Curve K2 shows the temperature-time curve in the oven when using a special partial heating output in addition to normal oven heating for the benefit phase. It can be seen that this curve is steeper, i.e. that the target temperature T1 is already in a much shorter time t1 of e.g. 6.5 min. is achieved. At this point in time t1 when the target temperature T1 is at least approximately reached, the oven control device automatically switches over from the heating phase to the heating phase, i.e.
  • the aforementioned partial heating output is switched off and the overshoot temperature T2 at time t2 is reached with a reduced heating output, after which this heating output is also switched off and the thermostatic control process takes place.
  • a special, additional display element goes out, e.g. again in the form of a lamp, which signals to the user that - now at a much earlier point in time t1 - the heating phase has now ended and the food can be placed in the oven.
  • the oven top heat e.g. in the form of an internal radiant heater and with UH which e.g. external bottom heat of the oven.
  • the oven also has a forced air fan G driven by an electric motor M, which is e.g. is surrounded by an LH circulating air heater.
  • This circulating air heater LH represents the above-mentioned partial heating output for the heating phase, while the other heating elements of the top heat and bottom heat serve to heat the oven during the heating phase and during the heating phase.
  • L1 a display organ is e.g.
  • L2 is another display organ, e.g. also in the form of a lamp that is directly assigned to the partial heating power LH used for the heating phase, i.e. is activated when the partial heating power LH is activated and goes out when this partial heating power is switched off.
  • this additional partial heating output there is a further temperature-dependent switch ST or a second control path of a common thermostat, which is dependent on the temperature prevailing in the oven, i.e. when the target temperature is reached e.g.
  • the normal radiators OH, UH can be switched on using a manually operated switch S1.
  • the switch S2 which can also be operated manually, is e.g. marked as a quick heat-up button and serves to carry out a quick heat-up process by pressing the switch S2 to switch on the additional partial heating power LH, which is then switched off again when the target temperature T1 is reached.
