Definitions

• the invention relates to a program-controlled household appliance with an operating panel, in which handles for entering individual functions of an individual operating program sequence, which can be called under a name and can run properly under microprocessor control, are arranged, and with a memory for different functions of this program sequence.
• Such a household appliance is known for example from DE 44 22 128 A1.
• This allows the factory program specifications to be adapted to customer requirements in that the electronic control is freely programmable via a data input and output unit with a display.
• further data or parameters must be entered in a manner that is not explained in detail so that the existing program specifications can be varied or supplemented. Since information about the type of input is missing, additional input handles are to be provided according to other known household appliances of this type which are not actually necessary for calling up stored program specifications.
• a display is also required for the known device.
• Washing machines are also known, in whose control panels also handles for setting certain program functions are arranged. Logical links for the operation of these handles are set up in such a way that initiated persons (e.g. customer service technicians) can call certain functions or certain customer service programs by entering a code of certain operating actions, namely the sequence of the operation of individual operating handles, the course of which the customer service technician can call Observation of the washing machine can provide information about its proper operating program sequence, the sequence of which in turn would take too long for the necessary observation.
• so-called demonstration programs can be called up by means of suitable codings, in which a certain operating program sequence of the machine is simulated without functional elements of the washing machine actually being be operated. This means that installed program sequences can be demonstrated on the control panel of the washing machine.
• washing machines are known whose microprocessor-controlled program control devices are led via a data bus to an external interface to which a computer (e.g. a laptop) can be connected externally via a bus line in order to make certain changes in the installed program of the microcomputer, e.g. Changes to program sequences or to parameter values of the relevant program sequence.
• a computer e.g. a laptop
• update functions e.g. Changes to program sequences or to parameter values of the relevant program sequence.
• update functions is the need to carry a large amount of equipment (e.g. computers and accessories) for changes in installed programs, especially since update actions usually relate to short and minor changes.
• the invention is based on the object of providing an operating action in a household appliance referred to at the outset which is suitable for carrying out corresponding update functions without having to use complex equipment for this purpose or having to provide additional operating handles which are not necessary for calling up stored program specifications.
• this object is achieved in that one or more specific sequences of function inputs serve as code for the setting of certain operating program sequences or certain parameter values of program functions.
• initiated persons are able to make changes to program sequences or program parameters that have already been installed by means of a certain sequence of operating actions on the manipulations provided and required in any case in the control panel.
• control panels in which a display in the form of an alphanumeric display is also provided, such input operations can also be checked.
• the parameter values can relate to the water level in the tub, the temperature of the tub, as well as the cycles and the duration for certain treatment steps during the operating program sequence.
• Another advantageous embodiment of the invention in a washing machine or dishwasher determines as program sequences the sequences of water supply, lye heating, drum movement, lye circulation and pumping out of the lye.
• the parameter values in a tumble dryer can change the temperature of the
• the interventions in a tumble dryer can relate to the sequences of drum movements, process air delivery, cooling air delivery and condensate removal.
• the sequence of functional entries can also be made using a rotary selector switch as an operating handle, which can be set to different rotary positions for entering the code. To confirm the entry in the relevant rotary position, for example, the additional actuation of a button that is already present in the control panel for any function or a push function on the rotary selector switch itself can be used.
• the control panel 1 arranged to the right of the handle shell 2 for a detergent drawer of the washing machine contains a number of operating handles, namely a rotary selector switch 3 and six keys 4 to 9. LEDs 10 to 15 are above the keys 4 to 9 to acknowledge the actuation provided, while an alphanumeric display 16 above a rotary selector 17 used for setting, for example, speed values is suitable for displaying parameter values (eg speed values).
• the button 18 is used only to switch the electronic control on and off and thus the entire washing machine.
• an electronic circuit board is arranged behind the control panel 1 (not shown), on which a plurality of electronic components are connected to one another by means of conductor lamination of the circuit board.
• Such electronic components regularly include microprocessors, memory chips, switches and the like.
• Operating handles 3 to 9 and 17 possible functional inputs are recorded by such microprocessors and memory modules and are generally used to determine certain operating program sequences and parameter values for a program which is then to run.
• Such program sequences and parameter values are defined by the manufacturer's installation in the program control electronics.
• an initiated person can change certain operating program sequences or certain parameter values of program functions by entering a certain sequence of functions on the operating handles. For example, he can perform a certain sequence of key operations in order to influence the duration of a washing phase or to correct the temperature of the alkali for a certain program sequence downwards or upwards.
• program entries can also be made by a combined operation of the rotary selector switches 3 and 17 and the keys 4 to 9.
• the order of the inputs can be determined by respective settings of specific rotary positions of the rotary selector switch 3 and / or 17, while the rotary positions to be entered can be determined by actuating a specific ten of the buttons 4 to 9 or by pressing the relevant rotary selector switch.
• the alphanumeric display 16 can be used, for example, to control the intervention. Certain display images provided and assigned for corresponding measures must be created, which confirm the correct intervention. In the case of parameter values to be changed, such images can be the display of certain numerical values.
• Program elements that can be changed in washing machines and dishwashers can be, for example, the following functions: water supply, lye heating, drum movement, lye circulation, pumping out the lye.
• program elements can be drum movement, clockwise rotation, counterclockwise rotation, process air supply, cooling air supply and condensate discharge.
• the following settings are possible as changeable parameters of program functions for washing machines and dishwashers: alkali level, alkali temperature, time duration, time cycles and drum speed.
• the following parameters can be set for tumble dryers: process air temperature, residual moisture, time duration, time cycles. The above information is only to be understood as examples of such program elements or parameters.
