Definitions
- the present invention relates to a method for controlling a heating-up period of a cooking oven. Further, the present invention relates to a system for controlling a heating-up period of a cooking oven. Moreover, the present invention relates to an oven provided for performing said method and/or comprising the system mentioned above.
- the maximum allowed current for a 230 V power supply is limited. This results in a limited power. For example, in Switzerland the maximum allowed current for a 230 V power supply is limited to 10 A, so that the maximum power is 2300 W. The limitation of the current extends the heating-up period of the oven.
- the object of the present invention is achieved by the method according to claim 1.
- the present invention relates to a method for controlling a heating-up period of a cooking oven, wherein
- the main idea of the present invention is the excess of the maximum allowed current and power, respectively, for a certain time, and a subsequent undershooting of the maximum allowed current and power, respectively, wherein the average current and/or average power do not exceed the maximum allowed current and power, respectively.
- This method allows a reduction of the time for the heating-up period of the oven, e.g. by about 30 %.
- the average current and/or the average power is equal or marginally smaller than the maximum allowed current or power, respectively, during the duty cycle.
- the average current and/or the average power may be equal or marginally smaller than the maximum allowed current or power, respectively, during the heating-up period.
- the upper current and/or the upper power exceed the maximum allowed current or power, respectively, by 30 % to 50 %, in particular by about 40 %.
- the lower current and/or the lower power is about 60 % to 90 % of the maximum allowed current or power, respectively, in particular about 75 %.
- the time of the first phase of the duty cycle is about 30 % to 45 % of the time of the duty cycle.
- the time of the second phase of the duty cycle may be about 55 % to 70 % of the time of the duty cycle.
- the method is performed by an electronic control circuit.
- the method may be also performed by a computer program.
- the method may be performed by a combination of an electronic control circuit and a computer program.
- the present invention relates further to a system for controlling a heating-up period of a cooking oven, wherein the system is provided for performing the method mentioned above.
- the present invention relates to a cooking oven, having a cooking chamber for cooking foodstuff and heating elements arranged at or in the cooking chamber, e.g. an upper heating element and/or a lower heating element and/or a convection heating element wherein the oven is provided for the method described above and/or the oven comprises the system mentioned above.
- the present invention relates to a computer program product stored on a computer usable medium, comprising computer readable program means for causing a computer to perform a method mentioned above.
- FIG 1 illustrates a schematic diagram of a current I as function of the time t according to a preferred embodiment of the present invention during a heating-up period of a cooking oven (not shown) having a cooking chamber for cooking foodstuff and heating elements arranged at or in the cooking chamber, e.g. an upper heating element and/or a lower heating element and/or a convection heating element.
- the diagram shows a time slot of the beginning of the heating-up period. Said time slot takes about two minutes. Usually the heating-up period takes a time less than 10 minutes.
- the diagram illustrates three current levels.
- An upper current I U occurs, when two heating elements of the oven are activated, a lower current I L occurs, when only one of the heating elements of the oven is activated.
- the heating elements are switched in parallel.
- the upper current I U corresponds with a higher number of activated heating elements of the oven
- the lower current I L corresponds with a lower number of activated heating elements of the oven.
- An average current I A defines an average value of the upper current I U and the lower current I L , wherein the calculation of said average current I A is weighted by the time T U of the upper current I U and the time T L of the lower current I L .
- the current I alternates between the upper current I U and the lower current I L , so that the current I forms a rectangular signal.
- the heating-up period of the oven comprises a number of subsequent duty cycles.
- Each duty cycle includes one phase with the upper current I U and one phase with the lower current I L .
- the time T U of the upper current I U is about 18 s
- the time T L of the lower current I L is about 30 s.
- the time T DC of the duty cycle is about 48 s in this special example.
- the time T U of the upper current I U is about 38 % of the time T DC of the duty cycle.
- the time T L of the lower current I L is about 62 % of the time T DC of the duty cycle.
- the upper current I U is about 14 A
- the lower current I L is about 7.5 A
- the average current I A weighted by the times T U and T L of the upper current I U and lower current I L , respectively, is about 10 A.
- the heating-up period with said current values can be used, if a maximum current of 10 A is allowed. For 38 % of the heating-up period the upper current I U of about 14 A exceeds the maximum allowed current of 10 A. For 62 % of the heating-up period the lower current I L of about 7.5 A goes below the maximum allowed current of 10 A.
- the average current I A corresponds with the maximum allowed current of 10 A. In general, the average current I A may not exceed the maximum allowed current.
- the upper current I U of about 14 A corresponds with an upper power P U of about 3220 W.
- the lower current I L of about 7.5 A corresponds with a lower power P L of about 1725 W.
- the average current I A of about 10 A corresponds with an average power P A of about 2300 W.
- the maximum allowed current of 10 A corresponds with a maximum allowed power of about 2300 W.
- the upper current I U or the upper power P U may exceed the maximum allowed current or power, respectively.
- the average current I A or the average power P A may not exceed the maximum allowed current or power, respectively. This method results in a decreased heating-up period of the oven.
- the upper current I U , the lower current I L , the upper power P U and the lower power P L are given by the electric properties of the heating elements of the oven and by the voltage of the power supply.
- the average current I A and the average power P A can be elected by the user, wherein the average current I A and the average power P A may not exceed the maximum allowed current and power, respectively.
- the time of one duty cycle T DC is given by the oven, wherein the user can optionally vary the time of one duty cycle T DC within a predetermined range.
- the method according to the present invention can be performed by an electronic control circuit. Further, the method according to the present invention can be performed by a computer program. At last, the method according to the present invention can be performed by a combination of an electronic control circuit and a computer program.
- the present invention can also be embedded in a computer program product which comprises all the features enabling the implementation of the method described herein. Further, when loaded in computer system, said computer program product is able to carry out these methods.
