Definitions
- the invention relates to a method for operating a microwave domestic appliance having at least one microwave source, at least one microwave antenna for irradiating microwaves in a treatment room and a control device for controlling the microwave domestic appliance based on microwave parameters, wherein in the method of the treatment room with multiple quantized Microwave parameters are applied to microwaves and an associated microwave reading is determined.
- the invention also relates to a correspondingly configured microwave domestic appliance.
- the invention is particularly advantageously applicable to self-contained microwave cooking appliances or to microwave combination appliances, e.g. on an oven with microwave function.
- the heating of food with microwaves in a designated as cooking chamber treatment room of a microwave cooking appliance should be as uniform as possible and with high efficiency.
- a variation of the microwave parameters such as frequency, amplitude and phase of the radiated microwaves can cause a change in a field distribution of the microwaves in the cooking chamber, which have the required properties with a suitable choice of the microwave parameters.
- microwave parameters A variation of microwave parameters is basically known. It is assumed that an ideal cooking process effected by means of microwave radiation can be determined by measuring and correlating the microwave power introduced into the cooking chamber via a microwave antenna system and the power radiated back to the antenna system via the cooking chamber.
- an absorption ratio AV is defined, which is defined for an antenna system with n antennas or channels as:
- ⁇ ⁇ (n) denotes an introduced ("forward") microwave power and P ref (n) a reflected microwave power of the respective channel.
- the reflected microwave power P r e f (n) may be composed of the intrinsic reflection of this channel in the cooking chamber and a transmission of microwave power from other channels.
- the absorption ratio AV is generally dependent on the choice of an m-component parameter tuple or parameter vector k
- microwave parameters k can include, for example, frequency, phase and / or amplitude and are adjustable as control parameters.
- Non-electrical quantities such as an (angular) position of a mechanical mode stirrer, can also be used as microwave parameters or vector components.
- All microwave parameters k are usually quantized and may in particular have a minimum value and / or a maximum value.
- the first microwave parameter k-1 can correspond to a microwave frequency which, for example, can assume values ⁇ from the value range [2400 MHz, 2401 MHz,. The value range thus has values which have a step size of 1 MHz or which are "quantized" with a step size of 1 Hz.
- WO 201 1/058538 A1 scans an m-dimensional parameter space and then supplies energy to the food to be cooked with suitable parameter vectors.
- WO 201 1/058538 A1 discloses a device for applying electromagnetic energy to a load.
- the apparatus includes at least one processor configured to receive information corresponding to a dissipated energy for each of a plurality of modulation space elements and to group a plurality of modulation space elements into at least two subsets, based on the obtained information relating to dissipated energy.
- the processor may also be configured to associate a power supply protocol with each of the at least two subsets, the power transmission protocol being different between the two subsets and governing the power applied to the load in accordance with each power transmission protocol.
- WO 201 1058538 A1 a homogeneous heating is thus achieved at a low value of AV. A high part of the introduced Microwave power is reflected back into the source, and there are no hot spots in the food, which would only result in a one-off heating. WO 201 1058538 A1 examines a parameter space once completely and can no longer follow changes, such as those caused by cooking processes.
- DE 10 2014 200 355 A1 relates to a method and a device for heating a medium with microwaves in a cavity of a microwave device, which is substantially enclosed by metallic conductive walls, wherein for homogenization of the field or to avoid hot spots a variation of the Microwave parameters, such as frequency, amplitude and / or phase, and other parameters made and for each set of parameters, a proportion of the absorbed power is determined, with a homogeneous heating of the medium to be heated is achieved, when preferably at parameter sets power is emitted into the cavity are associated with a low absorption ratio AV, wherein the absorption ratio AV is formed from the ratio of the difference between incident and received power and the radiated power.
- an optimization algorithm first searches an environment of an initial parameter vector as starting solution and continues in the direction of the parameter vector, which leads to the smallest absorption ratio in the investigated environment, after which examines the environment of this new parameter vector and again a step in the direction of the adjacent parameter vector, which leads to a lower absorption ratio AV.
- the method disclosed in DE 10 2014 200 355 A1 corresponds to a downhill simplex method. This procedure is performed iteratively until finding a minimum absorption ratio AV. At this point, microwave power is applied until the absorption ratio AV appreciably increases. Then the procedure starts again. Thus, even with DE 10 2014 200 355 A1, a homogeneous heating is achieved at a low value of ⁇ V.
- DE 10 2014 200 355 A1 is also static and first has to find a suitable parameter set or parameter vector before the cooking process begins.
- US 9 265 097 B2 discloses a method of processing an object and comprises heating the object by applying radio frequency (RF) energy, monitoring a value related to an absorption rate of the RF energy by the object during heating, and adjusting the RF energy in accordance with changes in a time derivative of the monitored value.
- RF radio frequency
- the object is achieved by a method for operating a microwave domestic appliance with at least one microwave source for generating microwaves, at least one microwave antenna for irradiating the microwaves in a treatment room and a control device for controlling the microwave domestic appliance on the basis of m respectively quantized microwave parameters, in which (a) microwaves are applied to the treatment space in accordance with a current parameter vector k and an associated microwave reading is determined; (b) a first vector a (hereinafter referred to as "acceleration vector" without limitation of generality) component by component based on a difference of that for the current one Parametric vector k determined microwave measured value and a microwave measurement value for a parameter vector whose respective component has been modified is calculated, (c) an m-component second vector v (in the following without limitation of the general unit is referred to as a "velocity vector”) by adding the acceleration vector a to a current velocity vector v and determining the modified velocity vector v 'as the new current velocity vector, (d) determining another parameter vector
- the method has the advantage that a trajectory of the movement of the parameter vector leads targeted and particularly effective to areas with at least locally extreme (minimum or maximum) microwave parameters and thus to a homogeneous and possibly efficient heating of the food or the food.
- the method has the further advantage that it is dynamic and can react in real time to rapid changes in the food caused by the cooking process, e.g. Foods that fall apart, deliquesce, change their liquid content by rapid evaporation, or otherwise show a rapid change in their reflectance.
- the microwave field introduced into the treatment room or cooking chamber adapts to the changes while the cooking process continues.
- a comparatively small subset of the parameter space or potential space spanned by the parameter vectors k is needed for adapting the introduced microwaves.
- the next adjustment is made on the basis of a subsequent run of steps (a) to (d) and is therefore always system-updated.
- the method is advantageously capable of finding operating points or parameter vectors which correspond to a particularly high reflection of the microwaves.
- the resulting avoidance of hot spots prevents a punctual heating of the food.
- the method is advantageously also able to find operating points or parameter vectors corresponding to a low reflection of the microwaves. With low reflection, more power is transferred to the food. This can be used to heat food or food evenly if the hot spots are evenly distributed in the food. It is particularly advantageous to go through as many working points or parameter vectors as possible with low reflection or locally minimal reflection. This variant allows a particularly high efficiency and results in a particularly low component load and a special low development of waste heat. It is a development of this that is omitted in semiconductor systems on a protective device (circulator), as found in operating points with low reflection or of areas around these points no harmful feedback to the semiconductor.
- the method has the further advantage that it adapts very quickly to the food to be treated.
- the operating speed only decreases linearly with the number m of the control parameters k m
- the operating speed increases exponentially with the number m.
- the method according to DE 10 2014 200 355 A1 also has to perform up to 3m-1 measuring operations per iteration for a complete scanning of the surroundings of a point and is therefore hardly suitable for higher-dimensional control tasks, ie control with a large number of control parameters.
- the microwave domestic appliance may be a self-contained microwave cooking appliance or a microwave combination appliance, eg an oven with microwave function.
- the at least one microwave source may comprise at least one magnetron.
- the at least one microwave antenna may include one or more microwave antennas or channels. Several microwave antennas may also be referred to as an antenna system.
- the at least one microwave source and the at least one microwave antenna may together also be referred to as a microwave system.
- the treatment room can be referred to as cooking oven in a configuration of the microwave domestic appliance as a microwave cooking appliance.
- microwave parameters corresponds to the use of m different microwave parameters.
- the fact that the microwave parameters are quantized comprises, in particular, that the respective values which the microwave parameter can assume are in each case stepwise adjustable.
- the microwave frequency can be the values [902 MHz, 903 MHz, 928 MHz] and / or [2400 MHz, 2401 MHz, 2500 MHz].
- the m microwave parameters correspond to vector components of the parameter vector k.
- the acceleration vector a is an m-component vector
- the microwave measured values can be measured in a basically known manner by means of the microwave domestic appliance, for example by means of a directional coupler.
- the product is defined here such that g ⁇ a itself is again a vector with the components gi ⁇ ai, g 2 ⁇ a 2 , and so on. g may alternatively be written as a diagonally occupied matrix.
- the value difference of the microwave measured value MW of a microwave parameter determines - depending on the choice of g - the direction and the value by which the parameter vector k is accelerated.
- step (d) depending on the respective velocity component v, it is determined whether, in which direction and possibly how much the microwave parameters k are changed.
- At least one action can be triggered upon the fulfillment of an abort condition.
- step (c) can also be carried out before step (b).
- the method usually leads to a parameter vector or operating point, which in particular corresponds to a local extremum (minimum or maximum) of the microwave measured value in the parameter space.
- the parameter vector can pause or pass through this extreme parameter vector or operating point.
- the microwave measured value is a reflectance RG of the microwave radiation.
- the reflectance RG can as To be defined. Alternatively or additionally, the absorption ratio be used.
- step (b) the respective component k, (i + j) of the component-modified parameter vector k mQ d is modified by changing a value of this component by a predetermined step width j.
- the step width j can basically be specified as desired. It is a particularly advantageous development that the control parameter k, (i) is moved in the positive direction of the screening or step sequence, that is, starting from the quantization or grid position ⁇ on the grid position ⁇ + j with j> 0 is moved, if v , takes a positive value. If V has a negative value, it is a development that is selected as the next raster position ij with j> 0.
- the change j is advantageously 1 in terms of amount, ie, that an adjacent value is used. It is a further embodiment that in step (c) the velocity vector v is modified by adding to the current velocity vector v a product of the current acceleration vector a and a predetermined scalar acceleration constant g.
- g is now a constant number that is the same for all components a.
- the product g ⁇ a is a vector with the components g ai, g ⁇ a 2 , etc. This embodiment is particularly easy to implement.
- the current parameter vector k is modified by virtue of its components k, by means of the associated components v. of the current velocity vector v.
- This embodiment is particularly easy to implement.
- step (d) is performed only when an amount of the velocity vector v reaches or exceeds a predetermined threshold. This makes it easier to find an extreme value of the microwave measurement value since small differences in the microwave measurement value no longer affect the parameter vector.
- step (d) for a component k is performed only when an amount
- the corresponding component v, of the velocity vector v reaches or exceeds a predetermined threshold value. It is particularly advantageous if j 1.
- This condition can be applied component by component and / or to the whole parameter vector.
- step (c) the velocity vector is modified by additionally subtracting a factor ("friction factor") f in opposition to a direction of the velocity vector.
- a factor "friction factor”
- the friction factor f causes the magnitude of the components of the velocity vector v to be reduced, thereby reducing the virtual velocity of the parameter vector in the parameter space, at least component by component.
- the friction factor f may be the same for all components or may be different component by component. That the friction factor f is subtracted in opposition to the direction of the velocity vector may include
- step (c) the velocity vector v is modified by being amplified at intervals. This gives the advantage that speed lost due to the friction factor f can be returned to the velocity components v i.
- the search strength of the method can be considerably increased by a suitable choice of the values of g and / or f.
- For the movement of the parameter vector k is given a chaotic or practically chaotic variable by f and the regular amplification of v, which considerably increases the statistical search strength and avoids repetitions or redundancies of the traversal in the parameter space.
- step (c) the velocity vector v is modified by being reset at intervals to a standard value, wherein the directional information of the individual components v, can be maintained. Obtaining the direction information is to be equated with a constant sign of v ,. This provides the advantage that the implementation can be implemented with very little computational effort.
- the time intervals are regular intervals. It is particularly advantageous if the component-wise amplification is provided with a component-wise random distribution.
- This development has the advantage that the movement of the parameter vector in the parameter space becomes "chaotic". For this development leads to a "fidgeting" and prevents jamming on certain Trajek- torien in the parameter space, such as an unlimited swinging back and forth in a narrow potential well, which can practically lead to a retention of hotspots and thus burns in the food.
- step (d) when for a component k, an edge of a range of values is reached, a sign of the associated speed component V, is reversed. This corresponds to a reversal of the velocity component V, at the edge.
- an initial parameter vector and an initial velocity vector are given as current vectors at the beginning of the method. It is a development that the initial parameter vector and / or the initial velocity vector are selected at random. It is still a further development that the initial parameter vector and / or the initial velocity vector are selected on the basis of history data, eg corresponding to a vector of a previously performed vector. process sequence or a position in parameter space whose environment has not yet been passed through.
- step (e) at least one action can be triggered upon the occurrence of at least one termination condition.
- step (e) with the occurrence of at least one termination condition the method with a different initial parameter vector and / or with a different initial velocity vector is performed again.
- step (e) with the occurrence of at least one termination condition the method with a different initial parameter vector and / or with a different initial velocity vector is performed again.
- This embodiment is based on the surprising finding that the parameter vector k is typically located much more frequently in a local area which surrounds a maximum or minimum to be reached and likewise gives high or low values of the microwave measured value. Regions with opposite (low or high) values to the type of extremum, on the other hand, are traversed quickly.
- step (e) is alternated in step (e) with the occurrence of at least one termination condition between a minimum search and a maximum search of the microwave value. This can be done with or without changing the initial parameter vector and / or the initial velocity vector. Changing between minima and maxima search can be dependent on a stalled or activated cooking program.
- step (e) with the occurrence of at least one termination condition, the current parameter vector is maintained. It is therefore a stable operating point maintained, for example, until the end of the cooking cycle. This can be particularly advantageous for short treatment periods.
- the at least one termination condition includes that, for a given number of continuous loops of steps (a) to (e), the parameter vector is not modified.
- the at least one termination condition includes that for a given number of continuous loops of steps (a) to (e) the microwave measurement value no longer appreciably changes. It is yet an embodiment that the at least one termination condition comprises that information of at least one dedicated sensor fulfills a predetermined condition.
- infrared sensors can monitor the food and, when detecting a hotspot, set the value of g to a negative number (equivalent to searching for points with maximum reflection) to better distribute the temperatures equally.
- the at least one termination condition includes terminating the method, e.g. by completing the associated cooking process. This can be done, for example, on the basis of reaching a preset cooking duration, ending a cooking program, reaching a predetermined cooking temperature, etc.
- termination conditions are not limited to this.
- the object is also achieved by a microwave domestic appliance with at least one microwave source, at least one microwave antenna for irradiating microwaves in a treatment room and a control device for controlling the microwave domestic appliance based on m quantized microwave parameters, wherein the control device by performing the method according to one of previous claims is set up.
- the microwave domestic appliance can be designed analogously to the method and has the same advantages.
- the microwave domestic appliance is advantageously a microwave cooking appliance, for example an independent microwave cooking appliance or a microwave combination appliance, for example an oven with microwave function.
- the controller 5 is configured (e.g., programmed) to run a method SO-S6 to operate a home microwave appliance 1.
- a method SO-S6 an initial m-dimensional parameter vector k_init and an initial-dimensional velocity vector v_init are first defined in a step S0 as the current parameter vector k and the current velocity vector v.
- a step S1 the treatment space 4 is subjected to microwaves in accordance with the current parameter vector k, and an associated microwave measured value MW (k) is measured, in particular in the form of a reflectance.
- an acceleration vector a is calculated component-by-component on the basis of a difference of the microwave measured value MW (k) and a microwave measured value MW (k mQd ) for the current parameter vector k in the form of a reflectance for a parameter vector k m0d whose respective component a , has been modified.
- the velocity vector v is modified by adding the acceleration vector a to a current velocity vector v and determining a modified velocity vector v 'as the new current velocity vector v.
- the current velocity vector v can be a product of the current acceleration vector a and a predetermined acceleration vector.
- n Trentskonstanten g be added.
- a friction factor f can be deducted, possibly also component by component.
- the velocity vector v can also be modified by increasing it at intervals.
- a further parameter vector k ' is determined by modifying the current parameter vector k by means of the new actual velocity vector v.
- the further parameter vector k ' is then defined as the new current parameter vector k.
- This modification may be performed component by component and, in particular, linked to an amount of the velocity vector or a respective component of the velocity vector reaching or exceeding a predetermined threshold. If an edge of a value range is reached for a component of the parameter vector k, a sign of the associated velocity component can be reversed.
- a predetermined termination condition is met. If this is not the case ("n"), a branch is made back to step S1.
- the abort condition may include that for a given number of continuous loops of steps S1 through S4, the parameter vector is not modified.
- An abort condition may alternatively or additionally include that for a given number of continuous loops of steps S1 to S4, the microwave measurement value MW no longer appreciably changes.
- At least one action is triggered in step S6. This action may include branching to step S0 and selecting another initial parameter vector k_init and selecting another velocity vector v_init. Alternatively, the last found parameter vector k can be kept constant for the remaining duration of the treatment process.
- ⁇ On, “an”, etc. may be taken to mean a singular or a plurality, in particular in the sense of “at least one” or “one or more”, etc., as long as this is not explicitly excluded, eg by the expression “exactly a "etc. Also, a number may include exactly the specified number as well as a usual tolerance range, as long as this is not explicitly excluded.
