The invention relates to an operating and display device () for a domestic appliance, comprising operating means for setting at least one parameter of an operating process of the domestic appliance, a light conductor part () for conducting light, a plurality of function symbols (), which each symbolize a respective selectable value of the parameter, and a lighting device () for backlighting the function symbols (), by means of which lighting device the function symbol () associated with the presently selected value of the parameter can be optically distinguished from the other function symbols (), wherein the operating means are designed as touch-sensitive operating means and have a touch-sensitive actuation surface (), which is arranged such as to overlap with the function symbols () and thus the value of the parameter associated with one of the function symbols () can be selected by touching the actuation surface () in an overlap area () that overlaps with one of the function symbols ().

Operating and display device for a domestic appliance, and domestic appliance

A method and apparatus for transmitting a measurement variable that is detected by a measuring unit and transmitted via a data transmission channel to a main control unit of a domestic appliance that is isolated from the measuring unit is disclosed. The measurement control unit is coupled to the main control unit via a data transmission channel through which a measurement variable detectable by the measuring unit can be transmitted to the main control unit. The data transmission channel is a line having a protective impedance.

Domestic appliance comprising a measuring unit and method for transmitting a measurement variable

A circuit for operating a household appliance, wherein the circuit includes a switched-mode power supply for converting the power supply of a public power supply network into direct supply voltage. The circuit also includes a controller that is connected to the switched-mode power supply for being supplied with the direct supply voltage and for controlling processes of the household appliance. An EMC filter is provided to protect the public supply network from interference signals from the household appliance. The EMC filter includes a condenser that is connected between a phase conductor pole and a neutral conductor pole of the public power supply network; a bleeder resistor that is connected in parallel with the condenser; and a switch that can be activated by the controller to connect the condenser and the bleeder resistor to the neutral conductor pole.

Circuit arrangements for operating a household appliance

A circuit for operating a household appliance, having a switching power supply for transforming a grid voltage of a supply grid to a direct current supply voltage, a controller for controlling processes of the household appliance that can be coupled to the switching power supply and supplied by the DC supply voltage, and a button by means of which the switching power supply can be coupled to the supply grid by closing an electrical switch. The switch has two mechanically stable states and can be transitioned from one mechanically stable state to the other by actuating the button and/or by an at least indirect energy input from the controller.

Circuit configuration for operating a household appliance

The invention relates to control unit for a domestic appliance, especially for a washing machine with a fascia panel () to which is assigned at least one control button (), indicator () or similar arranged within a panel opening (), with a boardfor mounting at least one electrical or electronic component () arranged at a distance behind the fascia panel (), and with a sealing element () arranged between the fascia panel () and the board () by means of which the at least one electrical or electronic component () is to be protected against water or similar, whereby the sealing element () is attached to the fascia panel () of the control unit.

A method is provided for operating a converter circuit, in particular a pulse-width modulated frequency converter circuit having a DC voltage intermediate circuit, which controls two or more winding sections of a polyphase dynamo-electrical machine, in particular a three-phase asynchronous motor for a laundry appliance. The method determines one or more parameters of the dynamo-electrical machine, before a rotating field is produced in the dynamo-electrical machine by the converter circuit. The parameters can be used to deduce a variant of the dynamo-electrical machine, and to select open-loop and closed-loop control parameters which are associated with the variant. Likewise, the method allows possible machine faults to be determined by using the parameters. Likewise, a converter circuit and a laundry appliance perform the method and have a converter circuit for controlling a polyphase dynamo-electrical machine, which, in particular, drives a drum which is mounted in the laundry appliance such that it can rotate.

A structural set having at least two different configurations of a control panel equipped with control elements organized differently from one another from right to left in mirrored symmetry. A standard carrier plate is mounted behind the control panel. The carrier plate receives at least one switching device actuable by one of the control elements of the different configurations of the control panel.

A programmable control panel includes handles for executing at least a part of the program sequence, and memory cells for controlling an appliance and for storing software codes. The handles are, particularly, push-buttons and switches. The handles are used for inputting individual functions of an individual operating program sequence. Each of the individual functions is assigned to a specific one of the software codes stored in a specific one of the memory cells. The handles are linked to a specific one of the individual functions and to an associated one of the memory cells. A controller includes memory cells that are permanently assigned to the corresponding push-buttons, and operation of the push-buttons results in specific functions being included in the program sequence of the main program for the household appliance. The control panel can be part of a programmable household appliance. In order to simplify the configuration of control panels and the electronic controller, which can be combined with a control panel for different controller variants, each function in the program sequence is assigned a specific software code, and the software code (for example, a numerical code) is stored by entering it in specific memory cells. As a result, the respective function is assigned to the associated push-button or push-buttons.

Programmable household appliance

Actuators on a control panel for entering single functions of an individual operating program cycle which can be invoked under a given name and can be properly executed under microprocessor control are also used for setting particular operating program sequences or particular parameter values of program functions. The actuators can be actuated in at least one sequence of function entries such that the sequence of function entries is a code for particular update functions.

Method for varying programs stored in a program-controlled household appliance

Impermissibly high scaling is ascertained of an optical measurement section in which the turbidity of a washing liquid is detected in a domestic appliance that is operated with hard water, such as a washing machine or dishwasher. The appliance has an evaluation circuit for the measured signals from the measurement section and a microprocessor for binding the measurement results into the sequence control system of the appliance. The system is suitable for indicating impermissibly high scaling and for taking into account attenuation of the measurement section by chalk deposits during the determination of the turbidity of the washing liquid. Before or during the initial commissioning of the appliance, a threshold value for the permissible attenuation of the measurement section by future chalk deposits is stored, during each working cycle of the appliance, the attenuation of the measurement section is measured during a cycle section which is carried out without clouded washing liquid, whereby the attenuation is transformed into a measured value and compared with the threshold value, and the microprocessor outputs a control signal for the sequence control system when the measured value has reached or approximately reached the threshold value.
