The bottom heating element 12 and the top heating element 14 are activated by the selector switch 24, when the steam cooking function is selected. The ring heating element 16 and the cook ing fan 18 are activated, when the push button 26 is pressed.
FIG 7 illustrates a schematic circuit diagram of the cooking oven 10 with a steam cooking function according to Fig. 1. The circuit diagram shows the bottom heating element 12 and the top heating element 14. The bottom heating element 12 and the top heating element 14 can be switched in series for an operation in steam cooking mode. For an operation in non-steam cooking mode, bottom heating element 12 and top heating element 14 are switched in parallel. In this configuration the heating elements are reduced in power for the steam cooking mode and effectively avoid a cracking of the coating, in particular enamel, due to critical temperature gradients. Optionally, it is possible, in a non-steam cooking mode, to activate only bottom heating element 12 or only top heating element 14.
FIG 8 illustrates a schematic circuit diagram of the cooking oven 10 with the steam cooking function according to an embodi- ment of the present invention. The circuit diagram shows the bottom heating element 12, the top heating element 14, the ring heating element 16, the cooking fan 18, the push button 26 and the indicator light 32. Further, the circuit diagram shows a thermostat 28 and a cooling fan 30.
The bottom heating element 12 and the top heating element 14 are connected in series. The ring heating element 16 and the push button 26 are connected in series. Said both series are con nected parallel to each other. In turn, said parallel series are connected in series to the thermostat 28. A temperature thresh old value of the thermostat 28 is selected on the temperature knob by the user.
The bottom heating element 12 and the top heating element 14 can be switched in series for an operation in steam cooking mode.
For an operation in non-steam cooking mode, bottom heating ele ment 12 and top heating element 14 are switched in parallel. The bottom heating element 12 and the top heating element 14 are di rectly activated and deactivated by the thermostat 28. The ring heating element 16 is activated and deactivated by the thermo stat 28 and the push button 26.
The indicator light 32 is activated and deactivated by the se lector switch 24 and by the push button 26. The cooking fan 18 and the cooling fan 30 are activated and deactivated by the same selector switch 24.
Preferably, the circuit diagram in FIG 8 relates to a steam cooking operation mode of the cooking oven 10, where bottom heating element 12 and the top heating element 14 are switched in series. For other operation modes the heating elements 12, 14 and 16 and the cooking fan 18 may be interconnected in another way .
The cooking oven 10 with the steam cooking function according to the present invention requires only one bottom heating element 12. In the steam cooking operation mode the bottom heating ele ment 12 and the top heating element 14 are connected in series. The bottom heating element 12 is also provided for other opera tion modes. The bottom heating element 12 is already present in a conventional cooking oven.
Fig. 9 illustrates a circuit diagram of the cooking oven with a steam cooking function according to Fig. 2, having a second bot tom heating element 13. The second bottom heating element 13 is connected in parallel with the bottom heating element 12, the top heating element 14 and the rear heating element 16. All of the heaters may be switchable by the thermostat.
Although an illustrative embodiment of the present invention has been described herein with reference to the accompanying draw ings, it is to be understood that the present invention is not limited to that precise embodiment, and that various other changes and modifications may be affected therein by one skilled in the art without departing from the scope or spirit of the in vention. All such changes and modifications are intended to be included within the scope of the invention as defined by the ap pended claims. List of reference numerals
