  • the control unit can be designed as a universally programmable arithmetic unit that can use, for example, a driver module with power electronics components for actuating the power units.
  • generic home appliances include a user interface for selecting a power level of the power unit from a number of discrete power levels.
  • the control unit is designed by suitable software to use at least one power allocation function to determine a desired power for operating the power unit depending on the selected power level.
  • Such household appliances are from the EP 1 273 851 A2 and the DE 10 2005 040 346 A1 known.
  • the object of the invention is in particular to equip a generic home appliance with improved ease of use for various types of users and to achieve a simple setting.
  • the invention is based on a domestic appliance with a control unit and a user interface for selecting a stage from a number of power stages for setting a step-adjustable operating parameter, wherein the control unit is adapted to use at least one assignment function to the operating parameter depending on the selected stage wherein the user interface comprises at least one setting means for changing the assignment function.
  • a user who does not place an emphasis on precise adjustment of the operating parameter, and therefore requires only a few power levels can choose a few-power mappings function, while a user who cares about a precise setting would be willing to accept a more complex set-up , can choose a high-resolution mapping function with a variety of performance levels.
  • the domestic appliance has a plurality of operating parameters, which may be, for example, heating stages of different heating zones of a hob, each having an allocation function, wherein the setting means is designed to simultaneously change the assignment functions of all operating parameters.
  • the setting means is designed to simultaneously change the assignment functions of all operating parameters.
  • the concept of the invention can be used, in particular, in domestic appliances which comprise at least one power unit, wherein the stage can then determine a nominal power of the power unit during operation.
  • a gain in comfort can be achieved by the flexibly adjustable assignment function, in particular if the user interface comprises a key for incrementing the stage and a key for decrementing the stage.
  • the user interface comprises a key for incrementing the stage and a key for decrementing the stage.
  • a large number of high-power levels can be annoying to users who do not care about high-resolution.
  • the stage is a heating stage and the target power is a desired heating capacity.
  • the idea of the invention would also be applicable, for example, to washing machines, vacuum cleaners or the like, the power unit then being a motor.
  • an application of the invention in electrical radiators or air conditioning systems would be conceivable that could be formed, for example, as a motor vehicle air conditioning systems.
  • the mapping function can be made flexible if the domestic appliance is equipped with at least one memory unit for storing at least two assignment functions.
  • the assignment functions can either be stored in the form of different parameters of a parametric basic function or as tables. Any representation and storage of the assignment function which appears expedient to the person skilled in the art is conceivable.

  • the values may, for example, correspond to a percentage of the target power at a maximum power of the power unit.
  • the resolution of the mapping function can be easily adapted to the needs of the user if the setting means is designed to set the number of power levels.
  • Unnecessary complexity can be avoided if the setting means is designed to select one of two or three possible values for the number of power levels.
  • Intuitive operation of the domestic appliance can be ensured in particular for the various assignment functions if the values of the various assignment functions are distributed at least substantially evenly between zero and a maximum nominal output of the power unit.
  • a simple transmission of the assignment functions to a plurality of operating parameters, each with an assignment function, can be made possible if the assignment functions differ in each case only by a constant factor.
  • the setting can be further simplified if the various operating parameters, which may be, for example, heating stages of different heating zones of a hob, are controllable via a respective assignment function, wherein the setting means can then be designed in particular for simultaneously changing the assignment functions of all power units.
  • the user interface comprises a display for displaying a selection menu for changing the assignment function.
  • FIG. 1 shows a domestic appliance, namely a hob, with four power units 10a - 10d.
  • the power units 10a-10d are heating elements of a heating zone.
  • the heating elements may be formed, for example, as induction heating elements or as radiant heaters and are arranged under a cover plate 12 made of glass or glass ceramic.
  • the home appliance further comprises a control unit 14 for operating the power units 10a-10d.
  • the home appliance is operable via a touch screen user interface 16 for selecting power levels of the power units 10a-10d from a number of power levels.
  • the control unit 14 is designed by suitable software to use at least one power allocation function 20, to determine a target power for operating the power unit 10a-10d depending on the selected power level.
  • the user interface 16 comprises at least one setting means 18 for changing the assignment function 20. This allows the operator or user to adapt the mapping function 20 to his individual needs.
  • the touchscreen user interface 16 includes a first button 22 for incrementing the power level and a second button 24 for decrementing the power level.
  • the setting means 18 the user can in particular determine a number of possible power levels.
  • the power level corresponds to a heating stage and the desired power corresponds to a desired heating power, which serves as a reference variable for a temperature control or as a parameter for controlling the heating element.
  • the heating element can be switched on and off periodically by the control unit 14, for example, in order to generate the desired heating power over the time average.
  • the control unit 14 comprises a memory unit 26 designed as a ROM or RAM memory for storing at least two assignment functions 20.
  • the memory unit 26 comprises memory locations for storing a list of 17 values explicitly specified below in an example, each of which is assigned to one of 17 power stages other than power level zero.
  • the values are used by the control unit 14 or by an operating program implemented in the control unit 14 as a parameter of the assignment function 20.
  • the values are stored as floating point numbers and correspond to an expressed relationship between the desired power and a maximum power of the power unit 10a-10d.
  • the control unit 14 operates the power unit 10a-10d at a target heating power, which corresponds to the percentage of maximum power given by the value.
  • the control unit 14 controls, via a corresponding interface and a suitable driver, the user interface 16 embodied as a touch screen.
  • the operating program which is executed on the control unit 14 represents various nested selection menus, in particular a FIG. 2 illustrated menu for selecting basic settings, for setting a language, parameters of a parental control and parameters of a power grid through which the cooktop is operated, the latter parameters include a supply voltage and a maximum power.
  • the menu of the basic settings there is an entry 28 for changing the assignment function 20, for setting a number of performance levels.
  • the touch screen therefore forms, in interaction with the control unit 14 and a driver of the touch screen and with the software of the control unit 14, a user-operable setting means 18 for setting the number of power levels.
  • the in FIG. 3 selection menu in which the operator can select one of three possible values for the number of power levels.
  • the operator can select a small number of 9 power levels.
  • the always adjustable power level zero is not included in each case.
  • Each choice corresponds to one of three possible modes of operation, each with a different assignment function 20.
  • the storage unit 26 stores three lists with three allocation functions 20 corresponding to the three possible modes of operation.
  • the assignment functions 20 or the lists can also be combined into a multi-column list.
  • the values of the assignment function 20 are in each case distributed at least substantially uniformly in a function that increases more than linearly between zero and a maximum setpoint power of the power unit 10a-10d.
  • control unit 14 comprises a timing arrangement 30 which is realized as a timer function and which starts or is reset to zero when a power unit 10a-10d is switched on or when the power stage is switched over.
  • Timing assembly 30 is for measuring an uninterrupted operating time of a power unit 10a-10d of the domestic appliance. If several power units 10a-10d are operated simultaneously, a plurality of timer functions run in parallel accordingly.
  • control unit 14 is equipped with a means 32 implemented as an emergency shutdown function in the software for automatically switching off the power unit 10a-10d after the expiry of a maximum uninterrupted operating time of the power unit 10a-10d.
  • the control unit 14 is therefore designed to determine the maximum uninterrupted operating time depending on the values in the list, since the list assigns a maximum operating time to the percentage of the maximum power.
  • the maximum operating time is a monotonically decreasing function of the value describing the percentage of the maximum power in the list.
  • the allocation function 20 is stored in the form of the abovementioned percentages of the maximum power of the power units 10a-10d, the maximum power of the different power units 10a-10d being different. As a result, the same list can be used for all four power units 10a-10d, the absolute values of the assignment functions 20 each differing only by a constant factor which corresponds to the ratio of the maximum powers of the power units 10a-10d.
  • the settings made via the setting means 18 are therefore used to simultaneously change the assignment functions 20 of all the power units 10a-10d.
  • mapping functions 20 may be stored as mathematical functions that may be dependent on a parameter stored in the memory unit 26. By made on the adjusting means 18 Settings, the function can be selected or the parameter used of a parametric mapping function 20 can be changed.
  • control unit 14 uses the percentage A determined in this way, on the one hand to determine the heating power H by the multiplication of the proportion A (possibly divided by 100%) with the maximum heating power H max and, on the other hand, the maximum operating time depending on the percentage A to determine.
  • a timer counts backwards from the maximum operating time and shuts off the heating element when the remaining zero time is reached.
  • the customizable mapping function may be implemented in other home appliances such as a washing machine or oven.
  • the power levels may correspond to wash temperatures or a speed of a spin cycle.
  • the power level can be used to adjust the temperature.
  • the desired temperature of a refrigerator can be selected via the choice of the power level.
  • coffee machines can be selected by the choice of power level, for example, a quantity of water or a quantity of coffee.
