Definitions
- the invention relates to a method for operating a set-top device on a working zone of a control gear and a set up for carrying out the method control gear.
- a method for transmitting the setting data of a cooking point of a cooking appliance to another cooking point of the same cooking appliance is characterized by the method steps: a) detection by means of a working independently of a disk on the cookware detection system, if cookware is located on a cooking surface, b) Detecting the current setting data of an occupied hotplate by means of a control unit; c) detecting by means of the detection system whether cookware has been moved from one cooking position to another cooking position; and d) transmitting the setting data of the first cooking position detected in method step b) to the newly occupied one by means of the control unit cooking. Furthermore, a cooking appliance for carrying out this method is disclosed.
- US 5,746,114 describes an intelligent cooking system comprising cooking utensils such as saucepans, soup pans, etc., which have a temperature sensor for detecting either the temperature of the cooking utensil or any contents therein.
- a plurality of heating surfaces each have a surface for carrying the cooking utensils and transferring heat to the cooking utensils.
- a temperature control knob for setting a desired cooking temperature and a timer button are also provided.
- a controller is for controlling the temperature of the heating surface based on temperature signals it receives from the sensor and the desired cooking temperature via an infrared interface with the temperature control knob, the timer button, the heating surface and the temperature sensor functionally connected.
- Each of the cookware and each of the heating surfaces are differentiated from the controller to track the movement of any cooking utensils between one or more heating surfaces.
- the desired temperature associated with the heating surface is transferred together with the cooking utensil to control the new heating surface.
- a desired cooking time is set, the remaining portion of the desired cooking time can be transmitted along with the desired cooking temperature.
- 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.
- 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".
- a set-top device can be any electrically operable device for food treatment, such as a small household appliance (coffee maker, waffle iron, etc.) or a cooking utensils (pot, pan, etc.).
- the operating device base station
- the operating device is adapted to transmit an operating power to the attachment device positioned at the work zone by means of inductive coupling.
- the operating device may, for example, be present as a compact unit or be equipped with at least one separate working zone, which is or can be operated via a control device (common in the case of several work zones). Under a working zone that surface of the operating device is called, to which an attachment device is operable.
- the working zone can be so pronounced that substantially only through it the associated alternating magnetic field is emitted for transformer coupling with the attachment device.
- the work zone may also be referred to as a cooking zone, however, the present invention is not limited thereto.
- the operating device has at least one receiver assigned to the working zone for the wireless reception of data from the attachment device.
- This receiver may be located in the working zone (i.e., in or under the working zone) or next to the working zone (in particular up to 5 cm next to the working zone).
- the receiver can in particular be arranged closer to its work zone assigned to it than to another work zone.
- the attachment device has a transmitter for wireless transmission of data to the operating device.
- a transmitter is generally understood to mean a transmitting device for access to a transmission channel to the receiver.
- the transmitter of the attachment and the receiver of the control gear are coordinated so that they can communicate.
- the transmitter and the receiver can operate on the same or the same data protocol (s) and use a same frequency band or bands.
- the transmitter can advantageously be set up to be fed by means of the operating power transmitted by the operating device. This means that the transmitter can only transmit if the attachment can draw power from the transformer coupling.
- the attachment device has at least one secondary coil for continuously receiving energy from the alternating magnetic field, in general: an electromagnetic excitation field. From the magnetic alternating field inductive absorbed energy is used on the one hand to power the cooking appliance (operation of a heating element, etc.) and on the other hand to power at least the transmitter and possibly other low-voltage components such as integrated circuits.
- the secondary coil may be followed by a switching regulator, which rectifies the energy coupled out of the power supply to a voltage level suitable for operating the low-voltage components.
- an effective vertical distance of the attachment device from the working zone within which sufficient power is still transmitted for the operation of the transmitter is less than 2 cm, preferably not more than 0.75 mm.
- a lateral offset within which sufficient power is still transmitted for the operation of the transmitter is preferably not more than 3 cm.
- the operating device is preferably designed such that a distance between two cooking zones is so great that an attachment device can only be operated on a single working zone.
- Presence of a set top device on an active work zone can then be detected by receiving data at the receiver associated with the work zone. Because the receiver receives data, means that an attachment device can pick up power from the alternating magnetic field and therefore must be in the near field of the working zone to operate the transmitter. The presence of an attachment device can thus be easily and reliably detected without dedicated attachment detection device (weight sensor, etc.) or position determination.
- a short-range transmitter may be used whose range is so low that its data is received only by the recipient of the associated work zone, but not by receivers associated with other work zones.
- the short range can be realized by a power setting and / or directional characteristics of the transmitter.
- a short-range transmitter need no elaborate measures to prevent crosstalk on the receiver to be provided.
- a short-range transmitter can have an antenna in the bottom of the attachment for a particularly simple and compact design.
- the signal transmission can be transmitted over the same turns over which the power is transmitted, for. B. from a secondary coil to the primary coil in unidirectional data transmission and between the two coils in bidirectional data transmission. This eliminates the need for a separate antenna.
- the signal transmission can alternatively be carried out via inductively coupled signal windings in the operating device and food preparation device, which are designed separately from the power windings.
- the signal winding (s) may or may in particular be arranged on a plane with the power windings, for. B. the power windings on the outside circumferentially. Due to the coil arrangement, the data transmission is also limited to the near field between attachment device and operating device, a lateral antenna radiation is negligible.
- the set-top device further includes at least one integrated circuit for processing data and outputting data to the transmitter based on the processing.
- the integrated circuit can thus process data, for. B. read, modify, link, caching, format, etc., and output this data or derived data to the transmitter for transmission to an external unit.
- Data to be processed may be provided by another unit, e.g. As a sensor, data supplied or be stored in or on the integrated circuit data, z. As an identifier (serial number, etc.) or a property of the attachment.
- the transmitter may be at least partially integrated in the integrated circuit. As a result, a particularly compact design is achieved. Alternatively, the transmitter is a different from the integrated circuit device.
- the transmitter may include a modulator and an antenna downstream of the modulator.
- the modulator may be integrated into the integrated circuit, but not the antenna.
- Removal of a set-top box from an active work zone can be determined by aborting a reception of data at the work zone associated receiver, since in this case it is assumed that the transmitter none of his Operation receives more power because it is no longer in the near field of the work zone.
- removal of an attachment device can be easily and reliably detected without dedicated attachment detection device (weight sensor, etc.) or position determination.
- the powered or energized attachment device can independently transmit data to the operating device, eg. B. cyclically within predetermined time intervals, z. B. every 100 ms, whereby an optimal data rate is adjustable.
- an optimal data rate is adjustable.
- measurement data, z. As a temperature, humidity or pressure, independently transmitted to the operating device, as a memory overflow can be prevented.
- the set top box may include a receiver for wirelessly receiving data from the operating unit, and the operating unit may include a transmitter associated with the work zone for wirelessly transmitting data to the set top box as stand-alone units or in the form of transceivers.
- This allows bidirectional data communication, which allows an adaptation of the attachment to the current operation and by means of which it is also possible to transmit data from the attachment to the operating device on request of the operating device.
- the only prompt data transmission reduces data overhead and allows a design with particularly simple and inexpensive components.
- the top-mounted device can be identified at least on the basis of the data sent by the attachment to the operating device.
- the set-top device can also be identified independently of the data transmitted by the transmitter, as disclosed, for example, in DE 101 56 777 A1. In doing so, a selection of data that can be used for identification (“identification data”) is not restricted.
- Identification data may include, for example: non-variable data such as: a serial number of the set-top box, a device type (pot, pan, etc.), a system affiliation (eg, to a particular set of devices), device features such as a presence of a temperature sensor, maximum power consumption, a material of the instrument bottom, coefficients (eg PID coefficients for a PID control), etc., or dynamic data such as: a current cooking temperature.
- This identification data is linked with the affected work area so that a clear assignment between the work area and the identification cation data is achieved.
- the operating data may include, for example, a mode (step control, temperature control, program flow, etc.) and the operating mode associated operating parameters or settings.
- Recognition can then be achieved by checking, in the case of a set-top device which is rearranged within a certain period of time after removal at a working zone, whether the data of the set-top device used for the identification or data derived therefrom are already stored. If this is the case, a replacement of the previously removed attachment is assumed.
- the predetermined period of time may for example be between 5 s and 3 min, in particular between 20 s and 45 s, especially at about 30 s.
- the attachment device can thus be recognized when the attachment device is restarted on an active work zone if the restart takes place within the abovementioned maximum duration. In this case, the times are coordinated so that in practice relevant actions of an operator, which only involve temporary removal of the attachment, such as adding ingredients or distributing meals, are included.
- a previously removed from the control gear attachment to an active working zone of the operating device can be recognized by checking whether the data used for identification of the attachment are already stored, and if so, an interrupted operation with the removal is resumed at the work zone of the recognized attachment device or offered to an operator for recording. An operator then needs to make no or only a few annoying adjustments of the work zone or operating parameters. It therefore eliminates a re-entry of previously set values with merely short-term movement of the attachment. This increases the ease of use, especially with a high complexity of the system due to an extensive equipment and many options. For this purpose, it may be particularly preferred that when the attachment device is removed from a first working zone and disposed within a predetermined period of time at a second working zone, in the assignment, the working zone associated with the attachment device is updated.
- the data used to identify the attachment device comprise a current temperature of the attachment device. Because it is unlikely that two structurally identical devices also have exactly the same temperature. If now a top unit removed, z.
- the attachment device can be recognized if the sensed temperature is within a predetermined temperature range around the previously stored temperature around and in particular has fallen back on a new touchdown.
- the temperature range can for example be determined empirically from a cooling process of the attachment device.
- the temperature as an identification feature may thus include a temperature range that takes into account a cooling of the attachment device within the predetermined period of time.
- the operating device is equipped with at least one working zone for operating a set-top device at the work zone, the operating device having at each work zone a primary coil for inductive coupling with the attachment device positioned at the work zone, and at least one receiver associated with the work zone for wirelessly receiving data from the workstation Attachment device has.
- the operating device is set up to detect the presence of a set-top device on an active work zone by receiving data at the receiver associated with the work zone.

- 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.

- 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.
- 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.

B. activated (turned on) and deactivated (turned off) and operating parameters arranged thereon attachment 101 are set. Also, an operation of each attachment 101 may be started.
- the pot 101 is equipped with an integrated circuit 116 for processing data and outputting data to a transmitter.
- a temperature sensor 127 for determining a temperature at the pot 116 is connected.

- FIG. 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.
- a heating path 222 in the form of an intertwined resistance thick-film web, which is heated when energized, and so on warms the pot bottom 220 to heat the food 221.
- 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.
- 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.
- 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.
- analog measuring electronics 225 measuring signals of various sensors of the pot 201 are sensed.
- 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.
- a self-temperature sensor 217 is present directly at a measuring input of the analog measuring electronics 225. This thus measures the temperature in the range of 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.
- the integrated circuit 216 has an A / D converter (not shown).
- the digital "raw data" provided by the analog meter electronics 225 are reformatted into a format compatible for communication with the driver 206.
- 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.
- the antenna 228 is designed here as a parallel to the pot bottom 220 extending signal winding.
- other measurement data can also be processed by the integrated circuit 216 and sent to the module. lator 226 forwarded as a measurement signal of a secondary-side power voltage.
- 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.
- 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.
- 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.
- 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).
- a digital / analog converter 231 is inserted between the control unit 210 and the power generation unit 212.
- a primary coil 211 is operated in the form of a spiral-shaped power winding, as already stated with regard to FIG.
- the power generation unit 212 generates an alternating power voltage applied to the primary coil 211, here for example between 10 VAC and 230 VAC at a frequency between 400 kHz and 100 kHz.
- the primary coil 21 1 generates an alternating magnetic field as an alternating field, which in turn is received by the secondary coil 214.
- an induction-based energy transfer (“transformer coupling”) results between the primary coil 21 1 and the secondary coil 214.
- the control unit 210 stores a link or association of a particular work zone with identification data and operation data received for identifying the pot 201 disposed at the work zone, which describes a current status of an operation of the pot 201.
- the storage can be done for example in a look-up table.
- the map data is updated, e.g.
- the control unit 210 also detects presence of an attachment 201 on an active work zone by receiving data on the work zone associated receiver 229, 230. It can be assumed that the process security that data is at least must be received over a predetermined time interval, z. Over several communication cycles to detect presence. In an analogous manner, removal of an attachment 201 may be detected, for example, by a lack of data at the receiver 229, 230 over one or more data transfer cycles.
- the pot 201 is placed on the operating device 206, for example on the working zone 113a of the working plate 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 become. 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.
- the top electronics 223 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.
- the top electronics 223 again sends signals via the transmitter 226,228, which are recognized by the operating device 206.
- a data transfer is interpreted as placing the pot 201 on the operating device 206.
- Fig. 3 shows a flow chart for a recognition process of a set-top device on an operating device, eg. B. as shown in Fig. 1 and Fig. 2.
- a top-mounted device is recognized on an active (switched-on) working zone of the operating device in that it sends data to the operating device through the working zone.
- the attachment device can be placed on an already active work zone or on a deactivated (disabled) work zone, the following is turned on, and then the identification process is started.
- the add-on device is identified at least on the basis of - all or selected - data ("identification data") sent from the attachment to the operating device, and the identification data is logically assigned to the work zone.
- identification data - all or selected - data
- the resulting assignment can be stored, for example, in an assignment table in the operating device.
- the operating characteristics of this mode for. B. the mode self (cooking, etc.), and any associated operating parameters, eg. B. a set target temperature, the work zone logically assigned.
- the resulting extended assignment can also be stored in the assignment table in the operating device.
- any data updated e.g. If, for example, the operating data (eg a current power level, a cooking temperature or a section of a cooking program), the assignment is updated accordingly.
- a subsequent removal of the attachment from the work zone is detected by aborting the data transmission from the attachment to the operating device (step S5).
- the extended assignment with the logical link between the working zone, the removal of current operating parameters and the identification data then remains stored for a predetermined period of 30 s.
- step S6 If, in the following step S6, an attachment of a set-top device is detected on a working zone of the operating device within the predetermined period of 30 seconds (which may be the same or a different working zone), the identification data associated with this set device are compared with the identification data of the previously removed device. If the identification data is identical or deterministically derivable from it (eg a temperature), the new work zone, the identification data and the operating features of the previously removed attachment device are linked to one another. This corresponds to updating the assignment to the current work zone (step S7). Subsequently, the operation of the attachment with the stored 'old' operating parameters is automatically resumed. An operator no longer needs to carry out any further action and, in particular, does not need to re-enter settings. If no same attachment has been detected within the predetermined period of time, the association is deleted (step S8).
- the identification data is identical or deterministically derivable from it (eg a temperature)
- the comparison of the identification data of a currently attached set-top device with each still stored set of identification data of a remote top unit is performed.
- an operable by the operating device device is not limited to a pot, but may include any other electrically operable attachment device, such as another cooking utensils (pan, etc.) or a household small appliance.
