Definitions

  • the invention relates to a system of the type mentioned in the preamble of patent claim 1 and a method of the type mentioned in the preamble of patent claim 5.
  • a method for detecting the identity of a pot on a hotplate of a hob and a system of a hob with a pot are known.
  • the hob has a pot sensor means by which the presence of a pot on the hob is to be detected.
  • the pot has a temperature sensor and a transmitter, whereby the transmitter is intended to transmit at least two data sets to a receiver of a hob control.
  • the first data set should represent an identification device for an individual pot, while the second data set should concern the temperature state of the pot measured by the temperature sensor. If the pot sensor means has detected the presence of any pot, a heating element should be activated using a power profile template in order to bring about a temperature change in the pot placed on the hotplate.
  • the temperature information sent back to the hob control should then be used to determine whether the temperature profile detected by the temperature sensor on the pot corresponds to the template of the power profile generated by the heating element. If the temperature profile and the performance profile template correspond to one another, the pot should be recognized as being placed on this hotplate using the pot identification device.
  • the invention therefore faces the problem of improving a preparation process on an inductive hob.
  • the advantage that can be achieved with the invention is, in particular, that a preparation process on an inductive hob is improved. Due to the triggering of the wake-up signal by means of a motion sensor on the set-up device and/or a control element on the hob and/or a control element on a third-party device, the operation of the inductive hob and thus the preparation process on the inductive hob is significantly simplified without compromising safety. Accordingly, the system according to the invention and the method according to the invention also conform to standards and can therefore be approved for inductive hobs in accordance with today's safety requirements.
  • the inductive hob provides that the heating coil can be controlled in the standby mode by means of the hob control in such a way that a transfer of operating energy from the inductive hob to the set-up device, which is set up on the cooking area assigned to this heating coil, is made possible by means of the heating coil .
  • the set-up device requires no or only a very small and therefore space-saving energy source.
  • an advantageous development of the system according to the invention provides that the transmitting unit or the transmitting unit and the measuring unit can be supplied with operating energy at a voltage induced by means of the heating coil into the induction coil of the device set up on the cooking area assigned to this heating coil.
  • the heating coil is controlled in the standby mode by means of the hob control in such a way that a transmission of operating energy from the inductive hob to the set-up device, which is set up on the hob assigned to this heating coil, is made possible by means of the heating coil.
  • a particularly advantageous development of the inductive hob according to the invention provides that the inductive hob can be automatically transferred from the standby mode to the operating mode by means of the hob control and depending on a response signal received in the standby mode by means of the receiving unit.
  • the ease of use of the inductive hob according to the invention is further increased without the safety of operating the inductive hob being impaired.
  • an advantageous development of the method according to the invention provides that the inductive hob is controlled by means of the hob control and depending on the in The response signal received in the standby mode by means of the receiving unit is automatically transferred from the standby mode to the operating mode.
  • the wake-up signal for transferring the inductive hob from its standby mode to its standby mode can be freely selected within wide, suitable limits.
  • the wake-up signal can thus be generated by actuating a control element arranged on the set-up device and in signal transmission connection with the transmitting unit. In this way, the wake-up signal can be triggered, for example, using the set-up device.
  • a user could press a corresponding button on the setup device.
  • the wake-up signal is activated by means of a motion sensor arranged on the set-up device and in signal transmission connection with the transmitting unit and/or by actuation of a control element arranged on the inductive hob control and in signal transmission connection with the receiving unit of the hob control and/or by actuation of a is generated by a control element arranged on a third-party device and in signal transmission connection with the receiving unit of the hob control.
  • the wake-up signal can be triggered, for example, using the set-up device.
  • the alarm signal can be triggered using a third-party device, for example a smartphone.
  • the alarm signal can also be triggered by an operation on the inductive hob, for example by pressing a button on the inductive hob. Accordingly, there are a number of options for transferring the inductive hob from standby mode to standby mode.
  • the supply of electrical power to the heating coil can be freely selected depending on the type and mode of operation within wide, suitable limits.
  • a further advantageous development of the method according to the invention provides that the electrical power with which the hob control controls the heating coil in the standby mode has an average value of less than or equal to 30 W, preferably less than or equal to 15 W. This ensures that the electrical power supplied to the heating coil in the standby mode of the inductive hob is safe from a safety perspective.
  • the electrical power with which the hob control controls the heating coil in the standby mode has a pause-power ratio of greater than or equal to 1000:1.
  • the break i.e. the interruption of the electrical Power supply to the heating coil is 2 s
  • the time interval in which the electrical power is delivered to the heating coil is 160 ⁇ s.
  • the pause is therefore significantly longer than the time interval for power transmission.
  • a particularly advantageous development of the method according to the invention provides that in the standby mode, at least one set-up device is automatically assigned to at least one hotplate of the inductive hob with a plurality of hotplates each inductively heated by means of at least one heating coil. This makes it possible to determine during the standby mode whether a set-up device has been set up on a hotplate of the inductive hob or not. If the set-up device is set up on the hotplate, the inductive hob can then, for example, be automatically transferred from the standby mode to the operating mode, so that the set-up device can be effectively energized for a preparation process using this set-up device by means of the heating coil assigned to this hotplate. Otherwise, i.e. if there is no association between a set-up device and a hotplate of the inductive hob, the inductive hob remains in standby mode.
  • a further advantageous development of the method according to the invention according to claim 11 provides that the hob control controls the heating coils with an assignment signal and supplies the transmitting unit with operating energy at a voltage induced by at least one of the heating coils in the induction coil of the device set up on the cooking area assigned to this heating coil and the transmitting unit of the set-up device uses the operating energy to send a response signal that identifies the set-up device and correlates with the assignment signal induced into the induction coil of the set-up device by means of at least one of the heating coils assigned to this cooking place to the receiving unit of the hob control or a third-party device that is in signal transmission connection with the hob control and that Response signal in an evaluation unit of the hob control connected to the receiving unit for signal transmission or the third-party device with the assignment signal at least one heating coil of this hotplate is compared and, depending on this comparison, the identified set-up device is assigned to this hotplate.
  • the advantages that can be achieved with this development are, in particular, that, on the one hand, no energy source has to be provided on the set-up device for the transmitting unit of the at least one set-up device.
  • the energy required for the transmitter unit is generated from the voltage induced in the induction coil of the installation device.
  • the transmitting unit is supplied with operating energy at a voltage induced by at least one of the heating coils in the induction coil of the set-up device set up on the cooking zone assigned to this heating coil and is thereby controlled in such a way that the transmitting unit of the set-up device sends the response signal to the receiving unit using the operating energy.
  • the automatic assignment of the at least one set-up device to the at least one hotplate is realized in a simple manner by controlling the at least one heating coil of the hotplate on which the set-up device is set up with an assignment signal that simultaneously sends the device identifying the set-up device and to the by means of at least one of the heating coils assigned to this hotplate in the induction coil of the set-up device correlating response signal to the receiving unit of the hob control, which transmits signals to the evaluation unit, or to a third-party device connected to the hob control in a signal-transmitting manner.
  • one or more features of the respective assignment signal such as rising edges, falling edges, signal duration, maximums and/or minimums, trigger the response signal to be sent by means of the transmitting unit of the respective installation device. If there are several heating coils assigned to a hotplate, only one of these heating coils must be controlled with an assignment signal. Accordingly, the operating energy required for sending the response signal is generated by means of the voltage induced in the induction coil of the installation device and the sending process itself is triggered.
  • a faster automatic assignment of the at least one set-up device to the at least one hotplate of an inductively heated hob having a plurality of hotplates is made possible.

  • the term “assignment signal” when controlling the heating coils of the hotplates as well as when inducing the induction coil of the at least one set-up device is to be understood in general terms. It can be accordingly the assignment signal is, for example, a performance profile.
  • the assignment signal can indicate that a predetermined limit value is exceeded or that the value falls below a predetermined limit value.
  • An interruption of the service as well as a reduction or an increase in the capacity are also conceivable.
  • more or less complex power profiles are also possible, for example, which have ramps and/or step functions and/or variable distances between power peaks/power dips and/or variable durations of power peaks/power dips.
  • an alternative advantageous development of the method according to the invention according to claim 11, which is alternative to the aforementioned embodiment, provides that the hob control controls the heating coils with at least one assignment signal and the measuring unit detects a vibration of the set-up device that correlates with the assignment signal induced in the induction coil and the transmitting unit detects a vibration that identifies the set-up device and sends a response signal correlating to the detected vibration of the set-up device to the receiving unit of the hob control or a third-party device in signal transmission connection with the hob control and the response signal is compared in an evaluation unit of the hob control or the third-party device connected to the receiving unit for signal transmission with the assignment signal of the at least one heating coil of this hotplate and depending on this comparison, the identified set-up device is assigned to this hotplate.
  • the advantage that can be achieved with this development of the method according to the invention is, in particular, that the automatic assignment of at least one set-up device to at least one hotplate of an inductive hob with a plurality of hotplates can also be done more quickly.
  • there is essentially no time delay in the automatic assignment due to properties of the at least one set-up device for example due to a temperature measurement on a set-up device designed as a pot that correlates to the induced power profile.
  • the response signal therefore does not relate to a temperature measurement or the like, but rather correlates more directly, namely without a significant time delay, with the assignment signal.
  • the term “vibration” here is synonymous with the terms “oscillation” or “shock”.
  • Vibrations that can be perceived by the human senses as well as those that cannot or only cannot be perceived by the human senses includes vibrations that are difficult to perceive.
