Definitions

  • the invention relates to an operating device explained in the preamble of claim 1 Art.
  • Such controls are on a large scale for a variety of devices, especially household appliances and there especially cooking appliances, such as microwave or electric stoves in use.
  • Modern controls are provided with a controller that is designed for automatic operation, so that the user only has to enter variable parameters that are converted by the controller into the desired operating procedure.
  • it is customary especially for cooking appliances to store complete programs, which then have to be set by the user only by area code. For example, there are programs that are specifically designed for the preparation of a particular dish, eg. B. thawing and finish baking a pizza are designed, in which case the user then only this program and additionally, if necessary, the weight of the pizza must choose from a number of specifications.
  • the selected operating state is then automatically converted by the controller when a start button is pressed. If the program of this particular operating state has expired, the controller includes a shutdown function, with which the device is switched off.
  • Rotary knobs have been proven for a long time.
  • Rotary knobs have long been used as power regulators, with the switchable power levels noted around the rotary knob, and the corresponding power level is then turned on immediately when the knob reaches the appropriate position and immediately turned off when it leaves.
  • knobs are also used to scroll through a menu, the controller detecting the amount of rotation of the rotary knob and correspondingly displaying successive menu items on a display.
  • the rotary knob is rotated when sinking. This can be done either unintentionally, if the rotary knob is retractable in any position, as is the case for example with rotationally symmetrical knobs; or the rotary knob must be turned into a specially defined countersunk position for countersinking. The latter would be particularly necessary if non-round knobs are used. For example, if such a non-circular knob for scrolling through a menu unscrewed from its suitable for lowering position, it remains in this twisted position when the shutdown function of the controller or by pressing the manual shutdown the device after completion of the operating state or after the program has expired is switched off.
  • the invention is therefore based on the object to make an operating device of the type mentioned safer.
  • the inventive design ensures that turning the rotary knob when sinking is not interpreted by the controller as the preselection of an operating condition.
  • the switching device used for this purpose is robust and reliable.
  • the signal supplied by the switching device on the rotary knob can be processed in a variety of ways to eliminate the preselection of an operating condition or to suspend or override.
  • the preselection program can be reset.
  • an additional shutdown function can be provided by the switching device.
  • the switching device can be used to detect a sinking condition.
  • the switching device includes a reed contact in cooperation with a magnet, in particular a permanent magnet, which is preferably arranged on the rotary knob.
  • the invention is particularly suitable for rotary knobs, which have a defined by a certain rotational position or by a first rotational position sinking position, which is the case especially for non-circular knobs.
  • the invention is particularly applicable where the rotary knob acts via a potentiometer on a bit generator that generates increment or decrement to change the operating conditions within the given possibilities.
  • Fig. 1 shows an embodiment of an operating device 1 according to the invention in plan view of a control panel 2.
  • the control device 1 can be used for each device, in particular for each household appliance and is shown in the illustrated embodiment as a control device for a cooking appliance in the form of a baking oven.
  • the control panel 2 is provided with the usual controls.
  • operating state should both individual operating parameters, such as the weight of the food, the desired operating time, the power level of a microwave, the temperature or the like and a specific mode, such as recirculation mode, top heat or bottom heat, with or without combination with Microwave and program-controlled cooking processes, where the parameters have been pre-tuned and stored specifically for the preparation of a particular foodstuff, include.
  • knobs 6a, 6b are present, but it can only be provided a rotary knob or more than two knobs.
  • control panel 2 includes the usual printed displays, such as 7, and a display panel 8 for displaying varying values.
  • the two rotary knobs 6a, 6b each contain a position marker 9 and are substantially identical, so that the following description is made on the basis of the rotary knob 6a, the rotary knob 6b being of analogous design.
  • the rotary knob 6a has a non-circular, long oval shape (so-called sword gag) and can be lowered by pressing almost flush in a first rotational position 1 in the control panel 2.
  • the control panel 2 includes a recess which exactly corresponds to the long oval shape of the control knob 6a and receives the control knob 6a in the sunk state, while the control knob 6a in the non-sunk state relative to this sinking opening about a perpendicular to Figure 1 extending axis of rotation 6 '. (Fig. 2) can rotate.
  • the rotary knob 6a thus has two defined and offset by 180 ° to each other lowered positions (hereinafter, the two countersunk positions are also referred to as first rotational positions I), ie positions in which the shape of the rotary knob with the shape of the sink opening is aligned.
  • first rotational positions I ie positions in which the shape of the rotary knob with the shape of the sink opening is aligned.
  • second rotational positions in all intermediate positions (hereinafter the intermediate positions are also referred to as second rotational positions), not be sunk.
  • the rotary knob 6a is connected via a shaft 10 with a potentiometer 11 and a bit generator 12 of a control device 13. With the bit generator 12, the stopper 4 is also connected.
  • the bit generator 12 detects the current resistance values generated by the rotary position of the rotary knob 6a on the potentiometer and converts them into access information about memory locations in at least one memory 14. This is shown here by a "pointer” 15 for better illustration.
  • the bit generator thus converts the resistance values of the potentiometer 11, for example, "clockwise rotation of five pulses" into access information such as "pointer up five positions".
  • the specified by the pointer 15 memory of the memory 14 is then displayed in the display 8 above the rotary knob.
  • the switch from memory to memory can also be done via controls 5a and 5b, so that the respective operating state to be changed is selected by the controls 5a, 5b, while the actual change is made by the rotary knob.
  • the recalled memory values are then routed via a BO control unit 16 to individual control signal lines 17, which lead to the individual, not shown, to be controlled devices, such as the clock, temperature control, all or selected heaters (top heat, bottom heat), the fan (Circulating air), the microwave or the like to run the operation as specified once the user has manually operated the starter 3.
  • controlled devices such as the clock, temperature control, all or selected heaters (top heat, bottom heat), the fan (Circulating air), the microwave or the like to run the operation as specified once the user has manually operated the starter 3.
  • the operating method can be ended either manually by actuating the stop function, for example by pressing the stop button or by the controller itself, for example, when the set time has expired.
  • the rotary knob 6 is still in the twisted position. If the rotary knob 6 is now to be sunk into the control panel 2 more, it must be turned back into the lowered position shown in FIG. However, the bit generator 12 interprets a turning of the rotary knob as a new area code and puts the device into operational readiness. Would now the start function selected, so z. B. the starter 3 is pressed, the device would start another operation. To prevent this, a switching device 18 is provided according to the invention and the rotary knob, preferably each rotary knob 6a, 6b, which acts in the manner described above assigned.
  • the switching device 18 includes a reed contact 19, which is connected via a control line 19a to the bit generator 12 and acts thereon.
  • the reed contact 19 is actuated via at least one magnet, preferably a permanent magnet 20, which moves with the rotary knob 6a in the axial direction along the axis of rotation 6 'in the lowered position.
  • the permanent magnet 20 is together with the rotary knob 6a in the lowered position, the reed contact 19 is energized by its magnetic field and provides a signal to the bit generator 12.
  • the reed contact 19 is not energized, as long as the rotary knob 6a not in its lowered position.
  • the signal of the switching device 18 can now be processed in various ways.
  • a further shut-off function is thus activated, which eliminates the operational readiness, which was produced by the rotation of the rotary knob again.
  • This accidental starting an operating function by accidentally touching the starter 3 is no longer possible.
  • the switching device 18 can be used to determine a lowered state of the rotary knob and, for example, certain functions do not run, as long as the rotary knob is still sunk.
  • a separate switching device 18 or either a separate magnet 20 or a separate reed contact 19 is provided for each countersink position of the rotary knob, two magnets 20 being provided in the illustrated embodiment for two countersunk positions. If the invention with rotary knobs with rotationally symmetrical cross section, used in particular in circular cylindrical knobs, so an annular permanent magnet for actuating the reed contact would be conceivable.
  • the invention is not limited to the described and illustrated embodiment.
  • any suitable switch can be used for the switching device.
  • the control device can also be modified depending on the type of cooking appliance equipped with the invention and the type of household or other appliance equipped with the invention.
