Definitions
- the invention relates to a method for operating a domestic microwave appliance, comprising a microwave generator for generating microwaves, a treatment space which can be acted upon by the microwaves, at least one sensor for detecting at least one sensor information and a display device.
- the invention also relates to a household microwave oven, which is set up for carrying out the method.
- the invention is particularly advantageously applicable to self-contained microwave devices and to microwave combination devices such as an oven / microwave combination device.
- Previously common practice in household microwave ovens are heating operations where a user selects or sets one of several desired microwave power levels. While at least for a cold household microwave oven at the beginning of a microwave heating process the actual microwave power radiated into the treatment room (“actual microwave power") corresponds to the nominal microwave power, the actual microwave power is often due to increasing losses in the power source due to overall heating, by intervention of protective limitations, in particular by thermal protection limitations (eg in high-voltage transformers) or by targeted regulation of the power of microwave ovens with inverter technology (eg on high-voltage switching power supply units for supplying the magnetron). If the household microwave oven is still warm at the beginning of the microwave heating process, e.g.
- the microwave target power may not be provided at the beginning of the heating process. If the household microwave appliance has a display device, this always indicates the microwave setpoint power selected by the user, even if the actual microwave power actually generated falls below the set microwave setpoint power.
- the object is achieved by a method for operating a domestic microwave appliance, comprising a microwave generator for generating microwaves, a treatment space which can be acted upon by the microwaves and a display device, in which method
- a currently available microwave power is determined and
- the microwave power is displayed in the display device.
- the user even when setting a period of time for a microwave heating process, is provided with an intelligible indication as to which maximum microwave actual power is at least initially available, which in turn has the advantage that the user receives an indication that whether the period of time originally provided by him for maintaining a desired treatment result should be prolonged and / or whether he can achieve a desired microwave power at all.
- the microwave power available is determined based on at least one sensor information results in the further advantage that the microwave Discretionary power is determined very precisely. There is no need to maintain large thermal safety distances, which allows a particularly high microwave power output, and yet it reliably prevents the household microwave appliance from reaching or exceeding safety-relevant thermal limit values. This is in particular in contrast to the possibility to determine the actual microwave power only on the basis of a set value such as the set microwave reference line.
- a time profile of the microwave power available is determined. This advantageously enables a particularly accurate prediction of the microwave power available in the future, thereby allowing a user to estimate with particular precision an available time duration for the microwave power actually supplied or to be fed in. It is particularly advantageous if the temporal course of the microwave power available from the household microwave oven is used as the default for the actually fed or to be fed microwave power, d. That is, the household microwave oven sets the microwave power generated by the microwave generator so that the microwave power fed into the treatment room corresponds to the pre-calculated microwave power available at that time.
- the microwave power fed in can utilize thermal reserves particularly effectively, in particular in contrast to the case in which the actual microwave power is determined only on the basis of an adjustment variable such as the set microwave reference line and then a chronological progression of the microwave power without consideration of changes in operation (such as a change in temperature of components or the intake of ambient air), environmental variables, etc.
- an adjustment variable such as the set microwave reference line
- a chronological progression of the microwave power without consideration of changes in operation (such as a change in temperature of components or the intake of ambient air), environmental variables, etc.
- the at least one sensor information can be determined several times in succession (for example in predefined fixed or variable time steps, eg every 0.1 s, every 1 s, etc.) and from this the current microwave power available, in particular its time profile , each recalculated.
- the current microwave power available in particular its time profile , each recalculated.
- the current microwave actual power is the microwave Disposal should not exceed or exceed
- the term "virtually does not exceed” is understood here to mean that the actual microwave power is, if appropriate, adjusted to a reduced microwave power only after a short setting period of the microwave generator, whereby this setting period is so short that it can on the operation of the household microwave oven and the treatment result has no practical influence. If a microwave power output is calculated that is below the current microwave actual power, the actual microwave power can be automatically lowered to the level of this microwave power available, or to an even lower level.
- a microwave continuous power represents a lower limit for the microwave power available.
- the microwave continuous power may be understood to mean a microwave power that is dimensioned so that it can be permanently maintained without overheating one or more of the appliance components of the household microwave oven.
- boost power a power called “boost power” is displayed, which corresponds to a difference of the microwave power available minus a microwave power output, d. that is, the microwave power available beyond the microwave endurance.
- the available microwave power is displayed to a user in a particularly catchy manner.
- “boost power” may be understood to mean a power or power difference that corresponds to the microwave power available minus the set microwave target power, d. that is, the microwave power beyond the microwave power.
- the boost power thus generally represents a measure of a microwave power or power difference which is available beyond a predetermined reference value (microwave power duration, set microwave target power or the like). Since the reference value is known, the boost power represents another representation of the microwave power available, and both values can be easily converted into one another and also used analogously.
- the household microwave oven may be a standalone microwave oven or microwave combination oven (such as an oven / microwave combination appliance, etc.).
- the microwave generator may be a magnetron operated by an inverter, for example, or a semiconductor microwave generator.
- the microwaves generated by the microwave generator are einstrahlbar or fed into the treatment room, directly or via a microwave guide.
- the treatment room can be set up or provided for applying food and can also be referred to as a food treatment room or cooking room.
- the display device may e.g. a screen, a touch screen, a segment display, etc.
- microwave disposal power Under a currently available microwave disposal power is understood in particular a microwave power, which is currently available at maximum and is therefore retrievable.
- the microwave power available thus represents a particular upper limit for the actual microwave power. If the microwave power is reduced due to e.g. Heating the household microwave oven to a level below the microwave actual power, the microwave actual power is reduced to the microwave power available.
- the microwave power can be displayed in the display device in any manner, e.g. as an absolute value, as a percentage, as a graph like a bar graph, pie chart, etc., or as a combination thereof.
- a microwave heating process may, in particular, be understood to mean a heating process initiated by the user for heating a food placed in a treatment space of the microwave oven.
- the microwave heating process may e.g. by pressing a start button or closing a door of the treatment room, etc.
- a measured value of a sensor or a value derived therefrom can be understood as sensor information.
- the microwave disposable power is determined based on a calculation model (hereinafter referred to as "thermal equivalent model" without limitation to the general public) for the household microwave oven.
- the thermal substitute model has the advantage that the microwave power can be brought up with high accuracy up to the thermal limit temperatures of the system components of the household microwave oven or even to individual components thereof, without exceeding these limiting temperatures.
- a further advantage is that the thermal reserve of the device components can also be predicted in terms of time, and thus a temporal course of the microwave power and the actually fed microwave power can be predetermined with high accuracy.
- the thermal replacement model represents all significant heat capacities and heat transfer resistances of device components of the household microwave oven.
- a heat capacity of the device components and their heat dissipation capacity via theoretical considerations (eg, including masses and heat transfer resistances).
- the theoretical considerations can be verified by laboratory measurements.
- the thermal replacement model is thus prepared in a device-specific manner so that only at least one sensor information from the current operation of the household microwave device is required for the accurate prediction of the still available thermal reserve (the still usable heat capacity) of the device components.
- Such considered device components may include, for example, a switched-mode power supply (inverter) for operating a microwave generator, power supply lines, fuses and switching devices (relays), as well as network filtering devices for network interference suppression.
- the device components can again consist of individual components which heat differently, which are often also thermally different in load, for example, have different operating limit temperatures.
- the thermal replacement model can individually consider both the device components and, if necessary, the associated components.
- the cooling of the device components takes place mainly by heat convection by means of cooling air and by heat conduction to a heat reduction.
- the microwave power available represents a stepwise microwave power. This makes it easier for a user to read the microwave power actually introduced or introduced during a microwave heating process. That the microwave power available is a step-wise microwave power, may include that the microwave power available only in one of several predetermined power levels. The steps may, for example, have a step size of 50 W or 100 W. It is a further development that the user-selectable power levels correspond to the power levels of the microwave power available.
- microwave power is displayed in steps, e.g. as numerical value, as graphic etc.
- a time remaining available for a currently used microwave power (“remaining time of availability”) is displayed in the display device.
- This provides the advantage that a user can easily see if the currently used microwave power is available for a long time or rather short compared to the set time duration of the microwave heating process. This allows a user to estimate even better whether he would like to extend a microwave heating process.
- a temporal course of the microwave power and, based on this, the microwave power actually introduced or to be introduced into the cooking chamber can be predetermined or predicted. This is possible, for example, by using the thermal replacement model.
- a "currently used microwave power” can be understood in particular to mean that it is the microwave power selected before a microwave heating process and / or that emitted by a microwave heating process.
- the at least one sensor information comprises at least one temperature information. This is particularly advantageous since temperature information can give a particularly reliable indication of thermal reserves that are still available and thus of microwave power available.
- the sensor information may also include information about other physical quantities such as humidity, speed, and so on.
- Temperature of at least one device component e.g. an inverter
- the temperature of the ambient air or of an ambient air or cooling air sucked into the microwave device can be understood as an air intake temperature. Their temperature level has a particularly strong influence on the cooling of the device components. Under an air blowing temperature, the temperature of one of the microwave device to the Surrounding blown air to be understood.
- the temperature of the treatment chamber can also be referred to as the cooking chamber temperature or treatment temperature.
- the device component may be an inverter, for example.
- a device intermediate space can be understood as meaning a space between the treatment space and an outer housing of the microwave device.
- the device interspace can be, for example, a switching room or electronics compartment in which an electrics or electronics of the microwave device, possibly including a magnetron and / or a switched-mode power supply (for example an inverter circuit), is accommodated.
- the sensor information may be measured by appropriate temperature sensors, humidity sensors, speed sensors, etc., and may also be referred to as temperature, humidity, speed readings, etc., or temperature, humidity, speed, and so on.
- the fan is a device fan, an electronic fan, a magnetron fan and / or an inverter fan.
- the microwave disposal power is additionally determined based on at least one setting information.
- a setting information may, in particular, be understood to be a set value from a group of a plurality of adjustable values of at least one device parameter and / or at least one adjustable device component.
- An adjustable value can also be zero.
- the setting information may be settable based on a setting by a user and / or a setting on the device side.
- Angular position of at least one flap includes. io
- the setting information makes it possible to calculate the remaining thermal reserves even more precisely.
- the fan speed gives an indication of a degree of heat dissipation.
- the fan speed is particularly variable and may itself be dependent on a temperature measurement.
- the predetermined microwave target power may be a user-specified power that a user, e.g. manually pretending to the microwave oven, or be a predetermined by the household microwave power, which can set the microwave oven, for example, as part of a selected cooking program. It is a development that, when the microwave power available, in particular its time course, is calculated taking into account the microwave target power, the microwave power available is calculated so that it does not exceed the microwave target power, in particular even if, without taking into account the microwave nominal power, a higher microwave power available would be available.
- the predetermined period of time may be a user-specified period of time which a user, e.g. manually pretending to the microwave oven, or be a predetermined by the household microwave oven time, which can set the microwave oven, for example, in the context of a selected cooking program.
- the fan speed comprises a desired fan speed of a device fan, a desired fan speed of an electronic fan, a desired fan speed of a magnetron fan and / or a desired fan speed of an inverter fan.
- the activity status comprises at least the statuses "On'V'Off", “On” / "On” or "InPerentY” ("Pause” status). If, for example, a microwave heating process is paused, it is practically not possible for a user to take into account the heat dissipation of appliance components occurring during a break, while in the present case this heat dissipation for determining the thermal reserve can be precisely taken into account. It is a development that the status information includes a length of a break. Other status information may e.g. an open or closed state of a flap, a door, a valve, etc. include.
- the microwave power available can be computed very reliably and accurately based at least on at least one temperature information and the predetermined desired microwave power.
- the sensor information, the setting information and the status information can also be referred to as device parameter information.
- the present object is also achieved by displaying in the display device the microwave power actually radiated into the treatment space.
- the microwave power actually radiated into the treatment space is displayed, even if the microwave power actually radiated into the treatment room is lower, for example the set microwave power requirement has been reduced to comply with thermal limit values.
- the present object is thus also achieved independently by a method for operating a domestic microwave appliance, comprising a microwave generator for generating microwaves. rowelden, a treatment space which can be acted upon by the microwaves and a display device, in which method the microwave power actually radiated into the treatment space is displayed, possibly parallel to the setpoint microwave power set on the user side.
- This task can be designed analogously to the method described above. Both methods are based on the common inventive idea of displaying to a user the microwave power actually radiated into the treatment room and thus enabling it to respond to a possible automatically set reduction of the microwave power actually radiated into the treatment room.
- the object is also achieved by a household microwave device which is set up to carry out the method as described above.

- the data processing device may include a microprocessor, ASIC, FPGA, etc.
- the data memory can be integrated into the data processing device, or a separate data memory can be coupled to the data processing device for data processing purposes.
- the control device may be a device that is different from the data processing device, or the data processing device may be integrated into the control device.
- the control device is in particular designed to generate the microwaves by carrying out the method described above, e.g. by means of suitable control software, e.g. for driving the microwave generator, e.g. an inverter of it.
- FIG. 1 shows, as a partial sectional illustration in front view, a household microwave appliance according to the invention.
- 2A-2D show a display device of the household microwave oven during several phases or portions of a possible microwave heating operation.
- a domestic microwave appliance 1 having a treatment space 2, a microwave generator 3, 4 operable by an inverter 3 and a magnetron 4 generated by the inverter 3 for generating microwaves, a wave guide 5 for conducting the microwaves of the Magnetron 4 in the treatment room 2 and a control device 6 for driving the inverter 3.
- a microwave continuous power of 600 W and a maximum achievable microwave power of 900 W is assumed.
- the household microwave oven 1 further has a user interface 7, 8, which has a display device 7 and one or more input fields 8.
- a user can set, for example, a desired microwave power EL and a duration th of a microwave heating process.
- the display device 7 and the at least one input field 8 can be integrated in a touch-sensitive screen ("touchscreen").
- the user interface 7, 8 is coupled to the control device 6.
- the household microwave oven 1 also has at least one sensor, here e.g. a temperature sensor 9 for sensing an air intake temperature T1 of an ambient air A sucked into the household microwave oven 1 by a cooling fan 10, a temperature sensor 11 present on the inverter 3 for sensing a temperature T2 on the inverter 3, or an electronics room having the inverter 3 (O. Fig.) And a speed sensor 20 for sensing a speed Uist the (2013)lüf ters 10. The speed Uist can deviate from a device automatically set target speed Usoll.
- the temperature sensors 9 and 11, the rotational speed sensor 20, and the cooling fan 10 are also coupled to the control device 6.
- the control device 6 can run a software, which sets up the control device 6 for performing the method described above.
- the software may be stored in a data memory 12, for example integrated in the control device 6.
- the software can set up the control device 6, for example, to determine the microwave power available, in particular its temporal course, on the basis of a thermal substitute model of sensor information and setting information.

- the setting information includes, for example, the setpoint speed Usoll of the cooling fan 10, the microwave setpoint power EL set via the user interface 7, 8, the set time duration th of the microwave heating process and / or a "pause" status.
- control device 6 uses the setpoint speed Usoll of the cooling fan 10 only if no measured or sensed speed is available.
- the control device 6 is thus a function of a data processing device for determining the time course of the microwave disposal power based on the at least one sensor information and setting information and based on data stored in the data memory 12 integrated.
- Fig. 2A shows the display device 7 of the household microwave oven 1.
- the display device 7 has a plurality of display areas 13 to 19, e.g.
- boost display area 15 in which it is indicated whether a boost power BL that exceeds the microwave output is available;
- time display area 18 for indicating a disposal remaining time VRD of the level of the boost power BL displayed in the bar graph 17, and thus indirectly the microwave disposal power
- At least one further display area 19 for example, one or more of the following information may be displayed:
- the boost power BL corresponds to the microwave power available, minus the constant microwave power output of 600 W.
- the currently fed microwave power ML is a stepped microwave power and can be available in steps of 600 W, 700 W, 800 W and 900 W. This corresponds to a display of the boost line BL of 0 W, 100 W, 200 W and 300 W. Each of the bars of the bar graph 17 thus corresponds to 100 W.
- a device state at the beginning of a microwave heating process 1 (in a "first phase") is shown.
- a time profile of the available or callable microwave power available on the basis of at least the available sensor information (s) T1, T2, Uist and optionally the setting information (EL), is previously provided by the control device 6.
- Usoll and / or th etc. have been calculated.
- the available boost power BL is recalculated when at least one device parameter information (e.g., a temperature value or the set microwave target power) noticeably changes.
- the available boost power BL is thus dynamically determinable or adaptable.
- the disposal residual duration VRD for which the boost power BL of 300 W and the microwave power of 900 W are retrievable is displayed in the timer display area 18, here e.g. 1 min and 10 s at the beginning of the microwave heating process.
- the disposal residual duration VRD is accurately known by calculating the time course of the microwave disposal power based on the thermal equivalent model.
- the time displayed in the display area 13 changes the remaining disposal time displayed in the timer display area 18 VRD for which the boost power BL of 300 W is retrievable, a remaining time indicated in the display area 19 until the end of the microwave heating process, etc.
- the microwave power available is reduced from 900 W to 800 W and, analogously, the boost power to 200 W.
- the power is automatically reduced
- the microwave power ML radiated into the treatment space 2 is reduced to the still available microwave power of 800 W or to the reduced boost power of 200 W.
- Fig. 2B shows the display 7 at the beginning of a second phase of the microwave heating process in which the available boost power BL is reduced to an intermediate level of 200W.
- the average boost power BL is displayed to a user in that only two bars are displayed in the bar graph 17 or only two bars are displayed filled. Consequently, the actually supplied microwave power ML of 800 W is displayed in the power display area 16.
- the second phase may initially be e.g. 50 seconds, as indicated in the timer display area 18 as the remaining VRD for this power level.
- the time of day displayed in the display area 13 changes analogously, and the remaining service time VRD displayed in the timer display area 18 for which the average boost power BL of 200 W can be called up is a remaining time displayed in the display area 19 until the end of microwave heating, etc.
- the microwave power is reduced from 800 W to 700 W and, analogously, the boost power is reduced to 100 W.
- the power is then automatically reduced also the microwave power ML actually radiated into the treatment space 2 is reduced, namely to the then still available microwave power of 700 W or to the reduced boost power of 100 W.
- Fig. 2C shows the display 7 at the beginning of a third phase of the microwave heating process in which the available boost power BL has been reduced to a boost level of 100W.
- This boost power BL is indicated to a user by: only one bar is shown in the bar graph 17 or only one bar is filled out. Consequently, a microwave power ML of 700 W is displayed in the power display area 16.
- the third phase may initially take 1 minute, as indicated in the timer display area 18 as the remaining VRD for that power level.
- the time profile of the boost power BL has been determined for the heating process prior to its beginning by means of the thermal equivalent model, namely here as a step-shaped course, which begins with the start of the heating process and then decreases stepwise:
- the time course of the boost power BL can be set to a value of zero, which can also be referred to as an end of a boost power or a boost operation.
- the household microwave oven can thereafter be permanently operated with the microwave continuous power of 600W.
- BL 0 W
- a microwave power ML of 600 W is displayed, which corresponds to the microwave continuous power DL.
- the fourth phase may e.g. 0 min 30 s, as indicated in the timer display area 18.
- the remaining time of the fourth phase corresponds to the remaining time of the entire microwave heating process.
- boost power BL or boost energy can be achieved by interrupting the microwave generation and / or by reducing the set microwave target power EL.
- the increased boost power can be visually displayed to a user by a correspondingly adapted display in the bar graph 17.
- the progressive-possibly dynamically changing-course of the boost power BL is thus indicated, for example, by stepping the bars step by step with increasing time progress or by continuously losing their degree of filling.
- the microwave heating process is so short that the boost power BL does not drop to 0 W, a remaining boost power BL remains with interruption of the microwave heating process (for example by its termination or pausing), which is also shown in the bar graph 17 is displayed accordingly. If a user would like to resume the microwave heating process or start a new microwave heating process, it is a further development that the desired microwave power EL which can be set by the user is limited to values that are at most equal to the still available boost power BL can correspond.
- a user can thus immediately recognize, by means of the present method, with the beginning of a subsequent microwave heating process on the basis of the bar graph 17, whether the preset desired microwave power EL originally desired by him is available and, accordingly, extend the time duration th in order to obtain a desired cooking result ,
- This is particularly advantageous if a user wants to treat several similar foods in a row by microwaves, for example for several persons. He then realizes that he is e.g. can heat a first food with full boost power BL, a subsequent second food can heat only with medium boost power BL and can heat another following third food only with low boost power BL and can according to the times th for to adapt each of the dishes.
- the boost power BL can increase again. For example, if there is an interruption of one minute between two consecutive microwave heats, it may be enough for the boost power BL to increase by one step during cooling, as indicated by the bar graph. The user can recognize this and adjust the set duration th of the microwave heating process accordingly. This is achieved in a particularly accurate manner by virtue of the fact that the thermal substitute model uses sensor information as input variable (s) and can precisely calculate the heat dissipation into the available boost power and thus the microwave power available.
- the set microwave target power EL can also be lower than the initially indicated boost power BL or the microwave power available.
- the bar graph 17 shows the reduction in the boost power BL caused by the operation of the household microwave appliance 1.
- the disposal remaining time VRD is then first displayed as the time duration for which the household microwave oven 1 can be operated on the set microwave nominal power EL. If the boost power BL or the microwave power available drops below the set microwave power EL, the actual microwave power ML is also reduced here (if the microwave target power EL is higher than the microwave continuous power) analogously to the procedure described above ,
- the microwave power available beyond the set microwave power setpoint can be understood and displayed as "boost power”.
- the boost power was then a measure of how much the microwave nominal power can be increased beyond the currently set level.
- the boost power can then correspond to the level of the microwave power available beyond the microwave power output without setting the desired microwave power.
- the boost power can also be applied in other stages or steplessly.
- the boost power can be displayed instead of a bar graph using another graphic such as a pie chart and / or as a numeric value.
- an indication of the disposal residual duration VRD of the level of boost power BL displayed in the bar graph 17 and thus indirectly the microwave dispense power may be displayed in the bar itself (e.g., as a contrast font).
- visualization of the progress of the temporal degradation of the indicated level of boost power BL may be through a degrading beam (eg analogous to a progress bar or "progressbar") instead of separately displayed bars.
- a degrading beam eg analogous to a progress bar or "progressbar”
- the microwave power actually radiated into the treatment chamber can be displayed, even without displaying the boost power, the microwave power available and / or the remaining power duration. With the interruption of a microwave heating process, the microwave power actually radiated into the treatment room when it is interrupted can be displayed.
