• the invention relates to a domestic appliance, in particular a dishwasher, according to the preamble of claim 1.
• Modern home appliances, especially dishwashers, are today with a variety of ads, d. H. LEDs or LC displays equipped, which are powered by an electrical control device with energy.
• an electric stove is known as a generic household appliance, in which a control device after actuation of an operating element supplies an associated display element for displaying an operating state and / or other data with electrical energy.
• switching means for a time switch are coupled here with operating elements provided in the switching panel of the hearth. When the stove is switched off, the timer is disconnected from the mains supply to save energy. Only when operating a control element, the timer is activated.
• the time switch display is continuously connected to the electrical supply network throughout the entire operating period. Some of the display elements may also be in operation before a program start or after a program end. In the long term, this can result in an undesirably high energy consumption.
• the object of the invention is to provide a domestic appliance, in particular a dishwasher, in which the energy consumption is reduced.
• the control device reduces or interrupts the power supply to the display element after a predetermined period of time. Ie. Within this predetermined period of time, the operator can check the setting made on the operating element of the household appliance by means of the display element supplied with electrical energy, such as an LC display. After the expiry of the Benen duration reduces or interrupts then the controller, the power supply to the display element. Alternatively, after expiration of the predetermined period of time, a minimum display, z. As an LED operated. This results in a long-term significant energy savings and thus a longer life for the display elements.
• control device can supply the display element with energy at predetermined clock intervals or reduce or interrupt the power supply. In this way, the operator can receive information about the operating state even after the expiration of the predetermined period of time.
• an additional information switching element may be provided.
• the control device can restore the energy supply to the display element after the predetermined time has elapsed.
• the information switching element can be provided together with the other operating and display elements in a control panel of the household appliance. With the information switching element can - in contrast to the other controls - no operating parameters or the like can be set, but only the power supply to the display elements are restored. The display elements are thus only lit up or activated when the operator wants to obtain information about the operating state by actuating the information switching element. Accordingly, after actuation of the information switching element, the control device can interrupt or reduce the power supply to the display element after a further, predetermined period of time.
• the household appliance For a simple and reliable operability of the household appliance can be provided at a plurality of display elements on the household appliance at least one operation display element, which displays the operating state of the household appliance continuously regardless of an operation of the information switching element. In this way it is ensured that the operator receives at least one feedback on whether the household appliance is switched on or off even with an off-duration in the above-described clock mode or after the expiry of the above-mentioned predetermined time. For a further, detailed need for information, the operator In addition, operate the information switching element, whereby the remaining display elements light up.

• a switch 25 is connected in each of the signal lines 22.
• the measures provided for in the signal lines 22 switch 25 are operatively connected to a timer 26 which is controlled via a control line 27 of the controller 17 and depending on the operating state, the switch 25 opens or closes.
• the control device 17 activates the switches 25 via the timer 26 in order to close the signal lines 22 to the display elements 7, 8, 9, 11. In this way, the control device 17 can supply the display elements 7, 8, 9, 11 with energy over a period of time At 1 predetermined by the timer 26. After the expiry of the predetermined period At 1 , the timer 26 of the control device 17 opens the switches 25, so that the power supply to the display elements 7, 8, 9, 11 is interrupted.
