Description

Method for operating a set-top device

The invention relates to a method for operating a set-top device on an operating device and an operating device set up for carrying out the method.

For example, DE 103 43 01 1 A1, DE 10 2005 022 352 A1, DE 10 2006 017 800 A1 and DE 10 2006 017 801 A1 disclose a power transmission from a working zone of an operating device to an attachment device by means of inductive coupling. An inductive coupling is understood to be the coupling of a primary coil of the operating device and a secondary coil of the attachment device via an alternating magnetic field, which is generated by the primary coil and tapped by the secondary coil. In the secondary coil, an induction voltage is generated by means of the alternating magnetic field, which can be used to operate the attachment device. Primary coil and secondary coil can also be considered as two halves of a separable transformer, which is why this type of coupling and power transmission is also called "transformer coupling".

US 6,953,919 B1 discloses a system and method for providing various cooking modes and the ability to automatically heat cookware and other objects using RFID technology, as well as the ability to read and write heating commands and to interactively contribute to their execution. An induction cooker with two antennas per hob is provided and includes a user interface display and a user input mechanism. The harness includes an RFID tag and a temperature sensor. In a first cooking mode, a recipe is read from the oven and the cooker helps a user to execute the recipe by automatically heating the dishes to specified temperatures and prompting the user to add ingredients. The recipe is written to the RFID tag so that if the harness is moved to another hob where the recipe has not been read, the new hob can read the recipe from the RFID tag and proceed with its execution ,

DE 10 2005 043 216 A1 relates to a method for cooking, cooking or baking a food in an oven, in particular in a household oven, the one with input means and having at least one display-equipped control with a memory element, comprising the steps of: a) activation of a dialog operation between the operator and the control by the operator by means of the input means; b) display of stored food to be prepared on the display by the controller; c) Selection of a food to be prepared from the food displayed according to step b) by the operator by means of the input means, wherein for the selected food cooking, cooking or baking parameters are stored in the storage means. In order to achieve improved cooking results, it is provided according to the invention that the method further comprises the steps: d) activation of a special function by the operator by means of the input means allowing the definition and / or use of alternative cooking, cooking or baking parameters; e) input and / or confirmation of alternative cooking, cooking or baking parameters by the operator by means of the input means; f) Start the cooking, cooking or baking of the food to be prepared by the operator by means of the input means on the basis of the alternative cooking, cooking or baking parameters.

It is the object of the present invention to provide a particularly user-friendly option for selecting a cooking program.

This object is achieved by means of a method and a control gear according to the respective independent claim. Preferred embodiments are in particular the dependent claims.

The method is used to operate a cooking utensil on a control gear. In this case, the operating device can initially operate the cooking utensils in any manner, for. B. by heat transfer (by resistance heaters, radiant heaters o. Ä.) Or by energy transfer via an electromagnetic excitation field (by means of eddy current heating or transformer coupling). The control gear performs at least the following steps: (a) detecting a type of cooking utensil and (b) offering a quantity of cooking programs limited to the type of cooking utensil. Under a kind of cooking utensils in particular a coarser division into pots, pans, roasters, etc. can be understood as well as a finer classification into different types of pots (saucepan, simmering pot, etc.), pans or fryers and so on. In the simplest case can be distinguished between only two types of cooking utensils, such as between a pot and a pan. Step (a) may be carried out by any suitable means be carried out. Thus, the type of Gargeschirrs done by means of a data transfer of identification data from the cooking utensils on the operating device. Alternatively or additionally, the type of cooking utensil may be determined from a response of the cooking utensil to an action of the operating device directed towards the cooking utensil, e.g. Example by means of a determination of a characteristic load of the cooking utensil in transformer coupling with the operating device in response to an energy pulse emitted by the operating device. In step (b) the operator is offered on the operating device limited to the type of cooking dishes amount of cooking programs, ie z. For example, cooking programs limited to pots (eg for cooking soups) or cooking programs limited to pans (eg for frying or frying). A cooking program can also be assigned to several types of cooking utensils, possibly with deviations in an associated control sequence.

This clear procedure allows an operator to select a cooking program in a particularly simple and user-friendly way. For the cooking utensils not possible or not meaningful cooking programs are not offered by default. However, it may be possible via a separately callable function, all cooking programs to call for selection, regardless of the attached cookware. Of course, an operation of a cooking utensil is also possible without performing the above method, for example by means of a power control mode (eg, step control) or a temperature control mode (eg, in the presence of a temperature sensor). Before carrying out the method, a selection of possible operating modes for operating the cooking utensil may be carried out.

Step (b) may comprise at least the following substeps: (b1) offering an amount of cooking program main groups limited to the type of cooking utensil; and (b2) offering, after selecting a cooking program main group, an amount of cooking programs also limited to the selected cooking program main group. The cooking program main groups can be meaningfully summarized groups of cooking programs, which advantageously include common groups of food to be cooked, z. B. in the sense of a 'cookbook'. Possible cooking program main groups may include, for example, soups, sauces, meat, fish, vegetables, etc. For example, the cooking program main group 'Soup' may only be offered if a pot has previously been detected, but not if a pan has been detected. On the other hand could z. B. the cooking program main group 'meat' both in recognizing a pan as well as recognizing a pot are offered. Then, after selecting a cooking program main group (for example 'meat') offered for more than one type of cooking utensils, only those cooking programs of the cooking program main group can be offered which are suitable for the previously recognized type of cooking utensil. Such a limited selection considerably increases the clarity and thus user-friendliness of an operator guidance. This is particularly advantageous if sub-steps (b1) and (b2) are then offered if the cooking programs offered in step (b) can not be completely displayed in a display device of the operating device. As an alternative to the sequence of steps (b1) and (b2), the cooking programs left over due to the selection of the cooking program main group can be offered by means of a scroll function or the like.

Step (b2) may comprise at least the following substeps: (b2a) offering, after selecting a main cooking program group, an alphabetically sorted set of - preferably alphabetically sorted - cooking program subgroups limited to the selected cooking program main group; and (b2b) offering, after selecting a cooking program subgroup, an amount of cooking programs also limited to the selected cooking program subgroup. The amount of cooking programs limited to the selected cooking program subset is a subset of the amount of cooking programs already limited by the type of cooking utensil and the selected cooking program main group. This allows - especially in a large number of cooking programs that are still possible even after selecting a cooking program main group - the selected cooking programs are displayed again clearly. This is particularly advantageous if sub-steps (b2a) and (b2b) are then offered if the cooking programs offered in step (b2) can not be completely displayed in a display device of the operating device. As an alternative to the sequence of steps (b2a) and (b2b), the cooking programs left over due to the selection of the cooking program main group can be offered by means of a scroll function.

Following a selection of a cooking program offered in step (b), (b2) or (b2b), a step (b3) may be followed by offering a setting of cooking parameters that can be set for the cooking program finally selected, e.g. B. a Gargutmenge, a weight, a state of cooking, a degree of browning, etc. The cooking program main groups, the cooking program subgroups and / or the cooking programs (in general: all available elements of a group) can advantageously be displayed completely on a display device of the operating device. If this is not the case, one or more of the following subordinate levels (n) may be offered for each of the groups, e.g. B. similar to step (b2a). As a result, an amount of cooking programs can be further limited so that they can be displayed by means of a display unit as a whole.

Preferably, the maximum number of completed bid stages is eight.

It is preferred to inform an operator of individual items to be selected if the items (eg, the cooking program main groups, the cooking program subgroups, or cooking programs) can be represented by pictures or videos.

The operating device is configured to run a method according to one of the preceding claims.

The operating device may in particular be set up to update the method. For this purpose, the operating device may for example have a wireless or wired network connection, for. For connection to the Internet, a home network or a control station. For example, certain cooking programs can be added or more cookware can be detected. This keeps the user-friendliness of the cooking program selection up to date.

The operating device is advantageously equipped with a display unit in the form of a touch-sensitive screen, since this results in a particularly comfortable and intuitive operation. Of course, but other panels are available, for. B. a combination of a non-touch-sensitive display unit with an actuator element field. In the following figures, the invention will be described schematically with reference to exemplary embodiments. It can be provided with the same reference numerals for better clarity identical or equivalent elements.

1 shows a system comprising an operating device for operating a set-top device by means of transformatory energy transmission and a pot arranged thereon as a top-mounted device;

Fig. 2 shows a sketch of a simplified control structure of the system of Fig. 1;

Fig. 3 shows a flow chart for selecting a cooking program.

Fig. 1 shows an attachment device in the form of a smart pot 101, which represents an electrical consumer. The pot 101 has a base body 102 with a lid and handles and a secondary coil 1 14 designed as a drive unit. The pot 101 is arranged on a surface of a worktop 105 of an operating device 106 for operating the pot 101. Under the worktop 105, a power transmission unit 107 is mounted. This has a housing 108 with an actuating element 109 for switching the energy transfer unit 107 on and off. Further, the power transmission unit 107 includes a primary coil 11 1 and a power generation unit 112 for supplying the primary coil 1 11 with an alternating current. The power generation unit 112 is formed as an inverter in this embodiment. The primary coil 111 is wound in the form of a plane spiral winding. During operation of the energy transfer unit 107 and the pot 101, the primary coil 1 11 is supplied with the alternating current and generates an alternating magnetic field. By means of a field flux of this alternating field, the primary coil 11 1 transmits by induction energy to the secondary coil 1 14, which is arranged on a drawn on the surface of the work surface 105 working zone (energy transfer area) 113 a. At a neighboring working zone 113b no attachment device is arranged. The secondary coil 1 14 is formed as a planar spiral winding. The working zones 1 13a and 13b are shown on the work plate 105 by means of a respective line 115a, 15b. In the secondary coil 1 14, a secondary voltage is induced by the magnetic field flux, which is used as the operating voltage for an operation of the pot 101. The pot 101 can be removed from the working zone 1 13, whereby the secondary coil 1 14 is separated from the primary coil 11 1. To the working zone 113 then more electrical consumers can be brought, such. As a coffee maker, a mixer, a charger, a fryer, a toaster, a kettle, etc. (also referred to as 'small household appliances'), each having one or more secondary coils and a wireless interaction of the respective secondary coil with the primary coil 11 first receive an operating energy.

In the worktop 105, a control panel in the form of a touch-sensitive screen 104 is further embedded on the display elements and actuators are freely programmable. The touch-sensitive screen 104 may be, for example, a liquid crystal or LED screen formed by a touch-sensitive film, e.g. As an ITO film is covered. As a result, a large number of different actuation elements, such as push buttons, circular sliders, linear sliders, can be displayed essentially as desired on the control panel, which allows a very flexible user guidance. By means of the control panel 104, in particular the two working zones 1 13a and 1 13b can be controlled independently of each other, for. B. activated (turned on) and deactivated (turned off) and operating parameters arranged there essay devices 101 are set. Also, an operation of each attachment 101 may be started. In particular, by means of the touch-sensitive screen 104 it is also possible to control an operator guidance for the selection of cooking programs, as described for example in FIG.

The pot 101 is equipped with an integrated circuit 116 for processing data and outputting data to a transmitter. To an input of the integrated circuit 116, a temperature sensor 127 for determining a temperature at the pot 116 is connected. The integrated circuit 116 cyclically senses the temperature sensor 127, processes the sensed temperature signals into a predetermined data and protocol structure, and transmits the thus processed temperature data to a transmitter. The transmitter has an unmarked modulator and a downstream transmitting antenna. As the transmitting antenna used here for power transmission secondary coil 1 14. The data from the secondary coil 1 14 radiated data signals are received by the serving as a receiving antenna of the operating device 106 primary coil 1 11, demodulated in a not shown demodulator of the operating device 106 and to a control unit 110th of the operating device 106 forwarded. Among other things, by means of the temperature data, the control unit controls or regulates ("Stove electronics") 1 10, which includes a microcontroller here, the power generation unit 1 12th

The control unit 110 has a memory, not shown here, in which various cooking programs are stored, as well as assignments or links of the individual cooking programs to Gargeschirrarten, and different group affiliations (cooking program main group, cooking program subgroups, etc.).

Although only two working zones 113a, 113b are shown on the operating device, fewer or more working zones can also be realized, in particular four or five working zones.

2 shows a sketch of a simplified control structure of a system comprising an intelligent pot 201 and an operating device 206.

The intelligent pot 201 has a main body 202, which is closed by a pot bottom 220 down, and can be filled into the food 221. On an underside of the pot bottom 220, a heating path 222 in the form of an intertwined resistance thick-layer web, which is heated when energized and so warms the pot bottom 220 to heat the food 221 runs. To its power supply, the heating track 222 is connected to a secondary coil 214 in the form of a spiral-shaped secondary winding and represents their load. From the secondary coil 214 and an electrical power to supply a pot electronics 223 is branched off. For this purpose, the pot electronics 223 has a switching regulator 224, which converts the output power voltage output by the secondary coil 214 into a low-voltage direct voltage. By means of the low-voltage DC voltage, the remaining parts of the pot electronics 223 are operated, of which an analog measuring electronics 225, an integrated circuit 216 and a modulator 226 are shown here. By means of the analog measuring electronics 225, measuring signals of various sensors of the pot 201 are sensed. For ease of illustration only three mounted on the underside of the pot bottom 220 temperature sensors 227 are shown here, but other sensors with the analog measuring electronics 225 may be connected, for. B. pressure sensors or humidity sensors. Furthermore, a self-temperature sensor 217 is present directly at a measuring input of the analog measuring electronics 225. This measures the temperature in the area this measuring input of the analog measuring electronics 225; Since the well electronics 223 are relatively compactly housed on a common board (not shown), the temperature at that measurement input is also considered to be representative of the temperature at the integrated circuit 216.

The analog measuring electronics 225 are connected on the output side to an input side of the integrated circuit 216, so that temperature data from the analog measuring electronics 225 are forwarded to the integrated circuit 216 for subsequent processing. For processing the temperature data transmitted analogously by the measuring electronics 225, the integrated circuit 216 has an A / D converter (not shown). In the integrated circuit 216, the digital "raw data" provided by the analog meter electronics 225 are reformatted into a format compatible for communication with the driver 206. In particular, raw data is converted to a predetermined data format and protocol format. The formatted measurement data is then cycled by integrated circuit 216, e.g. B. every 10 ms, forwarded to the modulator 226, where they are modulated onto a carrier signal, to then be transmitted from the modulator 226 via an antenna 228 to the operating device 206. The antenna 228 is designed here as a parallel to the pot bottom 220 extending signal winding. However, other measurement data can also be processed by the integrated circuit 216 and forwarded to the modulator 226, such as a measurement signal of a secondary-side power voltage. Also, other data may be processed by the integrated circuit 216 and passed to the modulator 226, such as identification data (ID code, etc.), and operational data, cyclic or, in the case of bidirectional communication, polled. The operating device 206 has a receiving antenna 229, which is likewise designed as a signal winding, which lies substantially opposite to the signal winding of the transmitting antenna 228 of the pot 201. The receive antenna 229 receives the modulated carrier signal radiated from the transmit antenna 228 and passes it to a demodulator 230 in which the data modulated onto the carrier signal is extracted and output again as readable digital data. Thus, both the data sensed by the analog measuring electronics 225 and the identification data and operating data supplied by the integrated circuit 216 are now present in the operating device 206. These data are further processed in a control unit ("hearth electronics") 210 and evaluated for the operation of the pot 201. Due to the coil-like configuration and opposite arrangement of transmitting antenna 228 and antenna 229, a near-field data transmission is achieved, which does not radiate significantly laterally and thus is not recorded by other receivers at other work zones. This prevents crosstalk and achieves an unambiguous assignment of pot 201 and operating device 206 only on the basis of the data transmission as such and without any other means.

Thus, the temperature data emitted by the pot 201 may be in the form of resistance values of the temperature sensors used, if they are designed as resistance temperature sensors. From this, the actual temperature at the underside of the pot bottom 220 can be determined in the control unit 210 by means of a look-up of the corresponding resistance / temperature characteristics in a look-up table, and the temperature of the cooking product can be deduced therefrom. For example, the temperature at the bottom of the pot bottom 220 can be equated with the temperature of the cooking product, or an empirically determined temperature difference can be added, which may also depend on the height of the measured temperature. The control unit 210 also receives inputs from a control panel 204, for example, about a desired cooking temperature for a temperature control. For this purpose, an operator has previously set the desired cooking temperature on the control panel 204 directly or via a cooking program. From the control panel 204 - unnoticed by the operator - also other control variables such as PID coefficients are sent to the control unit. In addition, in a cooking program operating mode, an operator prompt for selecting cooking programs or another setting of operating modes can be controlled via the control panel 204, such as, for example, B. in Fig. 3 described.

In the control unit 210, in the case of a temperature control, a control deviation between desired cooking temperature and actual cooking temperature can be determined, as well as a manipulated variable of the control loop, from which in turn a control voltage for controlling a power generating unit 212 in the form of power electronics is calculated and output. The control voltage is here in a range between 0 V (switched off) and 4 V (maximum). For this purpose, a digital / analog converter 231 is inserted between the control unit 210 and the power generation unit 212. By means of the power generation unit 212, a primary coil 21 1 is operated in the form of a spiral-shaped power winding, as has already been explained with reference to FIG. The power generating unit 212 generates for this purpose a power applied to the primary coil 211 power AC voltage, here for example between 10 VAC and 230 VAC at a frequency between 400 KHz and 100 KHz. The primary coil 211 generates an alternating magnetic field as an alternating field, which in turn is received by the secondary coil 214. In other words, an induction-based energy transfer ("transformer coupling") results between the primary coil 211 and the secondary coil 214.

For executing a cooking program mode, the control unit 210 may store various cooking programs, assignments or links of the individual cooking programs to cookware types, as well as various group affiliations (cooking program main group, cooking program subgroups, etc.) of the individual cooking programs.

If the pot 201 is placed on the operating device 206, for example on the working zone 1 13a of the worktop 105 shown in FIG. 1, energy can be transmitted from the operating device 206 to the pot 201 and data signals from the pot 201 to the operating device 206. Due to the transformer or inductive coupling between primary coil 211 and secondary coil 214, however, the energy transfer is possible only in a near field of the primary coil 21 1 for operating the pot 201. Typical maximum vertical distances (along the z-extension) between operating device 206 and pot 201 here are between 0.3 mm and 3 mm. A maximum offset in r-extent from a centered position is here up to 3 cm. If the pot 201 further away from the primary coil 211, the transmitted power is no longer sufficient for the operation of the pot 201. Then the transmitted energy is no longer sufficient for the operation of the pot electronics 223, which then stops their operation. The power required to transfer the pot 201, including operation of the pot electronics 223, is less than 5W, advantageously not more than 3W. An interruption of the data transmission is interpreted as removal of the pot 201 from the operating device 206

When approaching the pot 201 to an operating device 206, this can again enter the near field of the primary coil 211 and thus be supplied with energy again. In this case, the pot electronics 223 again sends signals via the transmitter 226,228, which are detected by the operating device 206. A data transfer is interpreted as placing the pot 201 on the operating device 206. Fig. 3 shows a possible flowchart for selecting a cooking program, z. On a system as shown in FIGS. 1 and 2.

In a first step S1, the operating device recognizes a type of cooking utensil that can be operated thereon, eg. B. a pan or a pot. This can be done by means of a transfer of a Gargeschirrkennung or in any other way.

In a following step S2, associated cooking programs are identified by the operating device on the basis of the type of cooking garnish detected, eg. By means of look-up in a look-up table of a control unit of the operating device. If a number of the cooking programs found exceeds a specified maximum number, which is to be displayed completely in the context of operator ergonomics (font size, icon size, display area of a display unit, etc.) in a display, then (so all found cooking programs can be displayed completely in the display unit , eg in the touch-sensitive screen 104 of Fig. 1), in a following step S3, these cooking programs limited to the type of cooking utensils detected are offered to an operator for selection, i. h., selectable in the display unit. In a following step S4, an operator can then select a desired cooking program. If at least one cooking program parameter is adjustable to start the cooking program, eg. As a quantity, number, degree of browning, etc., the at least one cooking program parameter can be offered in a subsequent step S5 for setting. Subsequently, the operator can start the cooking program.

If, however, so many cooking programs have been found for the detected type of cooking appliance (the number of cooking programs found exceeds the predetermined maximum number), so that they can not be displayed completely in a display unit within the framework of operator ergonomics, step S6 ensues in step S6 following step S2 the type of cookware offered limited amount of cooking program main groups to choose from. This amount can advantageously be displayed completely in a display unit within the framework of operator ergonomics, so that an operator does not need to move the screen of the display unit (for example the touch-sensitive screen 104 from FIG. A cooking program main group may advantageously comprise a group of cooking programs known to and / or intuitive to an operator can be detected. For this purpose, the cooking program main groups are advantageously defined so that they appear like chapters of a cookbook, z. B. with the terms 'sauces', 'soups', 'meat', 'fish', 'vegetables' etc.

After an operator has selected in step S6 one of the offered cooking program main groups by an operator in step S7, in a following step S8 the cooking appliance identifies the cooking programs associated with the selected cooking program main group, e.g. By means of look-up in a look-up table of a control unit of the operating device. This set of cooking programs identified in step S8 is a subset of the cooking programs already identified in step S2.

If a number of the cooking programs found in step S8 does not exceed a defined maximum number which can be displayed completely in the context of operator ergonomics (font size, icon size, display area of the display unit, etc.), then all the cooking programs found can be fully integrated into a display display the display unit), in a following step S9 these cooking programs now also restricted to the selected cooking program main group are offered to an operator for selection. In the following step S4, an operator can then select a desired cooking program. If at least one cooking program parameter is adjustable to start the cooking program, eg. As a quantity, number, degree of browning, etc., it is offered in a subsequent step S5 for recruitment. Subsequently, the operator can start the cooking program. The maximum number predetermined in step S8 may differ from the maximum number used in step S2.

However, if so many cooking programs have been found for the selected cooking program main group (the number of cooking programs found exceeds the predetermined maximum number), so that they can not be completely displayed in a display unit within the framework of operator ergonomics, in a following step S10, a selected cooking program main group limited amount of cooking program subgroups offered for selection. This can advantageously be displayed completely in a display unit within the framework of operator ergonomics, an operator thus does not need to scroll to the overview of the main cooking program groups or the like. A cooking program subgroup can advantageously have a group of cooking programs. men, which are grouped alphabetically according to their first letter, eg B. 'AD,' E-Fa ',' Fe - H ', T etc.

After selecting one of the offered cooking program subgroups by an operator in step S1 1, the cooking programs are identified and offered for selection in a following step S12 from the operating device, which belong to the selected cooking program subgroup, z. By means of look-up in a look-up table of a control unit of the operating device. This amount of cooking programs offered in step S12 is a subset of the amount of cooking programs already limited in steps S2 and S8.

For the exemplary embodiment shown, it is assumed that all cooking programs associated with a cooking program subgroup can be displayed completely in the display unit. In the following step S4, an operator can then select a desired cooking program. If at least one cooking program parameter is adjustable to start the cooking program, eg. As a quantity, number, degree of browning, etc., it is offered in a subsequent step S5 for recruitment. Subsequently, the operator can start the cooking program.

Of course, the present invention is not limited to the embodiment shown. So can, for. B. depending on the number of cooking programs, also be present more than three selection levels. For example, if the number of cooking programs in the alphabetically combined to 'AD' cooking program subgroup exceeds a common representable maximum number, hereinafter after selecting this cooking program subgroup 'AD' another selection of finely divided, z. B. alphabetically sorted, cooking program subgroups are offered, for. B. 'Ab-As', 'At-Be', etc. Also may be a bidirectional communication between pot and operating device. An operable by the operating device device is not limited to a pot, but may include any other cooking utensils (pan, etc.). LIST OF REFERENCE NUMBERS
