Technical Field

The present invention relates to a domestic food processor having a plurality of electrically operated functional components for preparing food in a pan. The recipe is accessible to a control unit of the home food processor, and a recipe step of the recipe causes the control unit to operate one of the functional components in a manner defined by the recipe step. The invention also relates to a method and a computer program product.

Background

Known as such

Such home food processors have access to digital recipes for semi-automated preparation of food. To prepare the food product, the user completes the recipe steps in sequence in the order given by the recipe, just as cooking according to the recipe in a cooking book.

Disclosure of Invention

The invention aims to provide a further improved household food processor.

A domestic food processor as claimed in claim 1, and a method and a computer program product according to the appended claims for achieving said object. Advantageous embodiments emerge from the dependent claims.

The object is solved by a domestic food processor with a plurality of electrically operated functional components for preparing food in a pan. A recipe may be accessible to a control unit of the home food processor, and a recipe step of the recipe may cause the control unit to operate one of the functional components in a manner defined by the recipe step. The recipe is configured such that the recipe defines at least one start condition (or start condition) for each of a plurality of recipe steps. The control unit is configured such that the control unit can set at least one next recipe step at the end of a previous recipe step at the latest depending on the start conditions of the recipe steps. Thus, the food can be prepared semi-automatically in a shorter time.

Thus, the recipe leaves the sequence of recipe steps open, i.e. the recipe does not define the sequence of recipe steps, but only defines at least one starting condition for a recipe step. The order of the recipe steps is set by the control unit at least based on the start conditions of the recipe steps. Thus, the order of the recipe steps is defined by the recipe in a variable manner in dependence of at least one start condition of the respective recipe step. Therefore, the preparation time can be shortened.

Since the control unit can variably and thus flexibly adapt the sequence of recipe steps to the current situation based on the comparison of the start-up conditions with the current situation at the start of or during the food preparation, the preparation time can be shortened. For example, if the user takes more time to cut onions than average, time can be saved by proposing another recipe step, such as preparing tomato paste for an onion pizza. The food processor may then chop and heat the tomatoes during the time the user is finished cutting onions. In a digital recipe for a traditional home food processor, the sequence of steps is actually imposed on the user, and the tomato paste recipe step will be performed after the onions are chopped. Furthermore, by defining the starting conditions of the recipe steps instead of a strict sequence of recipe steps, the preparation time can be shortened, since external food processing devices like ovens, blenders or cooking pots on ovens can be better considered when setting the sequence of recipe steps by the control unit. The control unit may adjust the recipe steps to an optimal time sequence according to the available external food processing equipment. By defining at least one enabling condition for each recipe step instead of a recipe giving a strict sequence of recipe steps, it is also possible to variably assign a recipe step to one of several available food processing devices.

Typically, functional components of a domestic food processor for preparing food products include, for example, heating elements and/or rotating tools for chopping or mixing.

The recipe refers to a digital recipe. A digital recipe is a data record that defines several recipe steps. The definition of the recipe step comprises at least one start-up condition. Furthermore, control commands to one or more electrically operated functional components of the domestic food processor are assigned to each recipe step. Optionally, the definition of the recipe may additionally comprise an algorithm allowing the control unit to determine whether the start-up condition is fulfilled depending on at least one input variable. In particular, the definition may comprise priority information and/or a priority algorithm. Preferably, the defining may comprise assigning a plurality of recipe steps to the recipe step module.

The starting condition of a recipe step means that the corresponding recipe step is only executed if the starting condition is met. In one configuration, the recipe step includes at least two start conditions. In one arrangement, the fulfilment of the start-up conditions may be checked or monitored by the control unit during the food preparation. In a particularly preferred alternative or supplementary configuration, the control unit may use the start-up conditions to adjust the recipe steps at the beginning of the food preparation to a sequence, preferably in a time-optimized sequence, which ensures that the respective start-up conditions for the individual recipe steps are fulfilled. In particular, this sequence set at the beginning of the food preparation is variable and can be changed during the food preparation. Alternatively, it is generally possible to set a later unalterable order.

In an embodiment, the control unit is configured such that the control unit sets the order of the recipe steps based on the start conditions of the recipe steps and at least one input variable. Thus, the preparation time can be shortened.

In one embodiment, the control unit is configured such that the control unit can set or change the order of recipe steps during food preparation. By flexibly adapting to the current situation, the preparation time can be reduced.

In an embodiment, the control unit is configured such that the control unit may determine whether a start condition for a recipe step is fulfilled based on the input variable, e.g. by comparing the input variable with the start condition. For example, the start-up condition may be that a predetermined temperature of the food in the pan is reached, which is heated or has been heated due to another earlier recipe step. The temperature can then be used as an input variable to start the relevant recipe step when the control unit determines from the temperature that the start-up conditions are fulfilled. In one configuration, the input variable is information that is dependent on the sensor signal. Preferably, the sensor signal is from a sensor of a domestic kitchen appliance (domestic food processor). In an alternative or complementary configuration, the input variable may be a user confirmation for completion of a particular manual recipe step or automatically generated status information regarding completion of the current recipe step. In one configuration, the start condition may be the completion of a particular recipe step or several particular recipe steps. Preferably, the control unit automatically identifies the completion of the recipe step when the duration of the recipe step expires.

In an embodiment, the control unit is configured such that the control unit can set the order of the recipe steps at the start of the food preparation. The entire sequence of recipe steps can be set at the beginning of the food preparation. The order of all recipe steps can then be set at the beginning of the food preparation. Alternatively, it is possible to change the order that has been set at the beginning of the food preparation. By "at the start of food preparation" is meant the time after the recipe has been selected by the user and/or before the first recipe step is activated or displayed to the user for activation.

In order to set the sequence of recipe steps at the beginning of the food preparation, the control unit evaluates the start conditions of the recipe steps, in particular together with at least one input variable. Preferably, the control unit only takes into account those start conditions of the recipe steps, the respective fulfilment of which may be determined according to the order of the recipe steps. In a preferred configuration, all start-up conditions for determining the sequence are taken into account at the beginning of the food preparation, wherein on the basis of assumptions on input variables which can only be determined or transmitted during the food preparation. These assumptions may preferably be provided by recipes.

The control unit comprises an algorithm for generating a sequence of recipe steps based on the start conditions and optionally input variables. Alternatively, the recipe may provide a sequence generation algorithm to the control unit, such that the control unit may set the sequence of recipe steps based on the start-up conditions and optionally on the input variables.

In one embodiment, the input variable describes the availability of an external food processing device. Thus, the preparation time can be reduced. In particular, the external food processing device is a stirrer, a cooking pot on a stove, a frying pan (pan) on a stove and/or an oven.

Preferably, input variables for the availability of the external food processing device are available from the control unit and/or are evaluated at the beginning of the food preparation together with the start-up conditions of the recipe steps in order to set the order of the recipe steps, in particular at the beginning of the food preparation. In one configuration, the start-up conditions for a recipe step include a plurality of alternatives for the food processing device that can perform the recipe step. In particular, a home food processor is an option for food processing equipment used in recipe steps where food is chopped, mixed, fried or heated. By taking into account the time capacity of the food processing equipment available for recipe steps, i.e. the home food processor itself and the external food processing equipment, a time-optimized sequence of recipe steps is obtained.

In one arrangement, the control unit simulates the various possible sequences, ensures that all start-up conditions for all recipe steps are met, and sets the sequence at the shortest food preparation time at the start of food preparation. In particular, a random generator is used to generate the various possible sequences in which all start-up conditions for all recipe steps are fulfilled. For recipes where the recipe steps are not very dependent on each other, there may be a majority of recipe steps that are of the same order, i.e. the order of several recipe steps may be interchanged (if all start-up conditions are fulfilled).

In one configuration, the input variables for the availability of external food processing equipment are obtained during food preparation. For example, in the process of preparing a food under the direction of a home food processor, if the ovens are used in parallel for other purposes and the cooking time set on the ovens has not elapsed, the home food processor may advance another recipe step and change the order of the recipe steps during food preparation accordingly. The same applies to the case where the oven suddenly unexpectedly fails and is no longer usable. In another example, if a cooking pot is available on the oven, the control unit can set the next step during food preparation to cook e.g. pasta in said cooking pot in order to complete the pasta sauce by the domestic food processor.

In one embodiment, the recipe is configured such that the start-up conditions may include a number of alternative options, for example, a number of available food processing equipment or a number of operational settings for the functional component, such as a desired number of revolutions or a desired temperature. As described below, a time-optimized sequence of recipe steps can thus be achieved.

In an embodiment, the control unit is configured such that the control unit saves (stores) the selection made for satisfying the start-up condition as a parameter for performing the recipe step. In this way, the control unit can, for example, in the case of simulations of various possible sequences of recipe steps, establish different choices for the respective start-up conditions, respectively, and take this choice into account in subsequent steps by saving it in parameters. A time-optimized sequence of recipe steps can thus be achieved.

In an embodiment, the control unit is configured such that parameters for a recipe step are set and saved based on input variables. A time-optimized sequence of recipe steps can thus be achieved.

In one configuration, the parameters of the recipe step may include a desired temperature, a desired number of revolutions, or a desired processing time in order to set and preserve the parameters during food preparation. For example, if the user selects a desired temperature that is lower than the recipe originally used for the recipe step, the user's desired temperature is used and time is saved. If the user selects a higher desired temperature, in one configuration, a warning may be displayed to the user or the desired temperature originally desired for the recipe may be used to save time. Preferably, an algorithm describing the relation between the input variables and the parameters is provided by the recipe, so that the control unit can set the parameters accordingly.

In an embodiment, the recipe is configured such that food processing equipment may be saved by selecting said parameter for each recipe step from a plurality of food processing equipment adapted to fulfill the start-up condition. In other words, the recipe step of determining the assigned parameter from the parameter is performed by a home food processor or by an external food processing device. In this way the total preparation time can be reduced.

In one embodiment, the recipe steps are defined by recipes such that two recipe steps can be performed in parallel in time. For example, the recipe step of chopping the raw materials may be performed by an external blender (mixer) while steaming the food in a home food processor for a longer time, and then adding the chopped raw materials to the food.

In one embodiment, the control unit is configured such that, for performing a recipe step, the control unit transmits control commands of the recipe step to at least one functional component of the domestic food processor and transmits further control commands of the recipe step performed in parallel in time to the external food processing device. Thus, the preparation time can be reduced as a whole.

In one configuration, the control unit includes a communication interface for receiving and/or transmitting data to an external food processing device. In particular, the data comprises input variables and/or control commands. Preferably, the transmission is wireless, for example, through a Bluetooth communication interface or a Wi-Fi communication interface. In particular, the input variables are transmitted by the food processing apparatus. In one arrangement, a plurality of food processing appliances may each transmit an input variable to the control unit. In one configuration, the controller (control unit) may transmit control commands to one or more external food processing devices. In this context, a separate aspect of the invention relates to a system comprising a domestic food processor and one or more external food processing devices, all of which have a communication interface.

In one embodiment, the recipe is configured such that two recipe steps that can be performed in parallel in time have a start condition that provides a delayed start of one recipe step relative to the other recipe step, a simultaneous start of a recipe step, or a simultaneous completion. Thus, the shortest possible preparation time can be achieved. For example, two recipe steps that can be performed in parallel can be done simultaneously by subtracting the recipe step duration of a shorter recipe step from the recipe step duration of a longer recipe step and using the difference as a delay time. After starting one recipe step, after the delay time expires and thus its start condition is fulfilled (in this regard), another recipe step is started.

In one embodiment, the recipe is configured such that the recipe assigns priority information or a priority algorithm to the recipe step or alternative selection of start conditions. In this way, the process of time optimization can be better incorporated into the sequential setup.

The priority information may be, for example, a priority value, so that a recipe step with a high priority value is arranged chronologically in the order of the recipe steps before a recipe step with a low priority value, if possible, or is started before a recipe step arranged in parallel. The priority algorithm may perform prioritization of a number of equally important recipe steps or alternatives. For example, the priority algorithm may specify that, in the case of equally important recipe steps, those recipe steps of shorter duration should be prioritized in the order.

In one configuration, if multiple, particularly otherwise equally important, food processing devices can be used as an alternative to the start-up condition, the home food processor will always have a higher priority in the form of priority information or in the priority algorithm. This gives priority to the use of domestic food processors which are usually already optimized for short preparation times. This further reduces the preparation time.

In one embodiment, the recipe is configured such that a plurality of recipe steps are combined into a module. The time-optimized sequence of recipe steps can thus be set particularly efficiently. In particular, the modules as a whole are arranged in a sequence. For example, a recipe may fix the temporal order of two recipe steps of a module, which should follow each other directly. In one configuration, a mutually fixed arrangement of all recipe steps of the recipe specification module is also possible, in particular a parallel and/or continuous arrangement in time.

In one configuration, the recipe is configured such that the start condition of a recipe step is independent of or dependent on another recipe step. In particular, the recipe is configured such that an association or dependency is set in a start condition for the start or completion of a particular other recipe step or a plurality of other particular recipe steps. In one configuration, a start condition is provided that specifies an immediately preceding recipe step.

The following three further aspects of the invention may be combined with the above features of the description and may also be used to shorten the time for food preparation.

A first further aspect of the invention relates to a method for controlling a domestic food processor having a plurality of electrically operated functional components for preparing food in a pan, the method comprising the steps of: a control unit of the domestic food processor accessing a recipe having a plurality of recipe steps by which operation of one of the functional components is controllable; and the control unit sets at least one next recipe step at the latest at the end of a previous recipe step, according to the starting conditions defined by the recipes for each of the plurality of recipe steps.

A second further aspect of the invention relates to a computer program product comprising instructions for causing a computer to carry out the steps of the method according to the first further aspect of the invention when the program of the computer program product is carried out by the computer, in particular by the control unit.

A third further aspect of the invention relates to a computer program product comprising a digital recipe having a plurality of recipe steps for controlling an electrically operated functional component of a home food processor for preparing a food product in a pan of the home food processor, wherein the recipe is configured such that the recipe defines at least one start-up condition for each of the plurality of recipe steps, such that the control unit can set the order of the recipe steps in accordance with the start-up conditions of the recipe steps.

Hereinafter, exemplary embodiments of the present invention will also be explained in more detail using the accompanying drawings. Features of the embodiments may be combined with the claimed subject matter, individually or in multiples, unless otherwise indicated. The scope of protection claimed is not limited to the exemplary embodiments.

fig. 3 shows a schematic diagram of a method for setting a sequence of recipe steps according to the invention;

fig. 4 shows a schematic view of a food preparation according to the prior art.

Detailed Description

Fig. 4 shows a food preparation according to the prior art, wherein a home food processor 1 performs a number of partially automated recipe steps according to a digital recipe file, not shown. The touch screen display 9 and/or the knobs 10 form a user interface. The recipe file fixedly and irrevocably determines the order of the recipe steps. After the user has put the tomatoes 14 into the pan 4 (indicated by "+") at the corresponding prompt, the tomatoes 14 are chopped by the rotating tool 2 and the user pours the semi-finished products 19 into the bowl 18 for temporary storage. After cooking the pasta 15 by heating by the heating element 3 and stirring by means of the attachment 8 of the tool 2 in the pan 4, another raw material 16 is added to the cooked pasta 15 together with the semi-finished product 19 in the bowl 18, the food mixture 17 being heated. The prepared food product 20 can now be taken out of the pan 4 and consumed.

Fig. 1 illustrates the preparation of the same food product 20 as shown in fig. 4, but completed in a shorter preparation time by using the present invention. The saving of time by performing two recipe steps 11, 12 in parallel is only an example. In other instances, not discussed in detail herein, time may be saved, for example, by specifically scheduling the recipe steps or by changing the order of the recipe steps in response to a particular situation or known characteristics of the user.

In the example shown, the home food processor 1 accesses the recipe 6 shown in fig. 2. As schematically shown in fig. 2, the recipe 6 comprises and defines a plurality of recipe steps 11, 12, 13 without specifying a fixed order. The definition of the recipe steps 11, 12, 13 by the recipe 6 comprises at least one start condition for each recipe step 11, 12, 13, so that the control unit 5 can set the order of the recipe steps 11, 12 based on the start conditions of the recipe steps 11, 12, 13. The recipes 6 can be saved in a data carrier, a memory of the control unit 5, a cloud memory or an external database, wherein the home food processor 1 comprises a respective communication interface for accessing the recipes 6.

In this example, as shown in fig. 3, the control unit 5 evaluates the input variables 7 together with the start conditions of the recipe steps 11, 12, 13 to set the order of the recipe steps 11, 12, 13. In the example shown, the input variables 7 describe the availability of a plurality of external food processing devices 21, 22, 23 as shown in fig. 1.

As shown in fig. 1, generally applicable food preparation devices are a household food processor 1 and an external mixer 21, an external frying pan 22 on an oven and an external cooking pan 23 on an oven. The control unit 5 receives information about the availability of the external mixer 21, the external fryer 22 on the oven and the external cooking pot 23 on the oven via a communication interface not shown, alternatively or additionally via a user input by a user. The information about availability is represented by input variables. In particular, the oven transmits information about the availability of frying pan 22 and cooking pan 23, preferably from at least one heating plate for frying pan 22 and/or cooking pan 23. Preferably, the availability of frying pan 22 and cooking pan 23, respectively, is considered by the user as allowed or confirmed.

The control unit 5 of the home food processor 1 now evaluates the starting conditions of the recipe steps 11, 12, 13 based on the recipe 6 (fig. 2) and the at least one input variable 7 (fig. 3). In one configuration, the desired food processing process (chopping, stirring, mixing, heating, cooking, baking) is defined and/or the control unit 5 distributes the food processing process to the (internal) functional components 2, 3 of the external food processing device and the domestic food processor 1, respectively, under the start-up conditions of the recipe steps 11, 12, 13. Alternatively or additionally, the start-up conditions comprise a plurality of alternative selections of the food processing apparatus for the respective recipe steps 11, 12, 13. In one embodiment, the display, preferably the touch screen display 9, is a functional component. In particular, the display or touch screen display 9 shows user instructions for manually performing steps or sub-steps of the recipe 6, e.g. adding ingredients to the pan 4. The addition may be detected automatically, e.g. by using a scale not shown or confirmed by the user, e.g. in particular through a user interface. The selection of one of a plurality of possible food processing devices 1, 21, 22, 23 for the respective recipe step 11, 12, 13 can be stored by means of parameters.

For example, in the example shown, it is provided in the starting conditions that the recipe step 13 (heating the food mixture 17) is performed both after the recipe step 11 (cooking the pasta 15) and after the recipe step 12 (chopping the tomatoes 14) is completed. In the recipe step 13, a food mixture 17 is heated, which consists of the cooked pasta 15 of the recipe step 11, the semi-finished products 19 of the minced tomatoes 14 of the recipe step 12 and other raw materials 16.

Furthermore, it may be defined, for example, by the recipe 6 that these recipe steps 11 and 12 are executable in parallel in the start-up conditions of the recipe steps 11 and 12. Furthermore, it may be defined, for example, by the recipe 6 in the start-up conditions of the recipe steps 11 and 12 that since the duration of the recipe step 11 is short, the recipe step 12 may be started after a time delay with respect to the recipe step 11, in particular in case of a parallel arrangement, so that both recipe steps end at about the same time. This allows the user time to clean the pan 4 of the domestic food processor 1, for example, without increasing the total preparation time.

The control unit 5 has received the following information from the input variables 7: blender 21 is not available and frying pan 22 on the oven and cooking pan 23 on the oven are available. Depending on the starting conditions, frying pan 22 cannot perform any recipe steps 11, 12, 13, so that frying pan 22 is already cancelled when determining the order of recipe steps 11, 12, 13. The control unit 5 simulates a number of possible sequences of recipe steps 11, 12, 13, which may ensure that the start-up conditions are fulfilled. In particular, the priority information of the individual recipe steps 11, 12, 13 is taken into account, whereby, for example, for the recipe step 13, a home food processor 1 with a higher priority has to be used than, for example, a cooking pot 23 on the stove.

At the end of the evaluation, the control unit 5 sets a sequence in which the preparation time is shortest, ensuring that all the start-up conditions are satisfied.

The results are shown in FIG. 1. The food processing device is marked with "-" and is not intended to be used by the control unit 5 for the recipe steps 11, 12, 13 in question, according to a set sequence comprising the above-mentioned parameters for setting the assignment of the recipe steps 11, 12, 13 to the food cooking devices 1, 21, 22, 23. For the sake of simplicity, in the example shown in fig. 1 not all individual recipe steps have been described as such individually, e.g. the recipe step of adding the respective raw material to the pan 4. The addition of raw materials may also be a separate recipe step and may thus be defined in the recipe 6 by at least one start-up condition.
