Household appliance with control element

Abstract

A household appliance includes at least one control element for modifying at least one operating parameter of the household appliance. At least one modification of at least one operating parameter which modification has been executed last is resettable by a reset control element. In a method for operating a domestic appliance, a most recently executed modification of an operating parameter can be reset by an operator.

What is claimed is: 
     
         1 . A household appliance comprising:
 at least one physical control element operable to input a sequence of a plurality of modifications, each of the plurality of modifications modify at least one operating parameter of the household appliance; and   a physical reset control element configured to reset, within a predefined period of time, at least one most recently made modification from a sequence of recently made modifications,   wherein the at least one most recently made modification is carried out within the predefined period of time.   
     
     
         2 . The household appliance of  claim 1 , wherein the sequence of recently made modifications includes the at least one operating parameter modified by the at least one physical control element. 
     
     
         3 . The household appliance of  claim 1 , wherein the physical reset control element is configured to reset a number of modifications most recently made from the plurality of modifications of the at least one operating parameter made using the at least one physical control element. 
     
     
         4 . The household appliance of  claim 1 , wherein the at least one operating parameter is modified as a result of an actuation of the control element. 
     
     
         5 . The household appliance of  claim 1 , wherein the at least one operating parameter is modified as a result of a number of actuations of the at least one physical control element carried out consecutively, wherein the number of actuations are carried out consecutively within the predefined period of time. 
     
     
         6 . The household appliance of  claim 5 , wherein the predefined period of time is at least three seconds. 
     
     
         7 . The household appliance of  claim 1 , wherein the predefined period of time is approximately five minutes. 
     
     
         8 . The household appliance of  claim 1 , wherein the at least one most recently made modification is resettable after the household appliance has been switched off, up to another predefined period of time. 
     
     
         9 . The household appliance of  claim 1 , further comprising a memory device coupled to the physical reset control element, the memory device being configured to store the most recently made modification and to restore the most recently made modification by actuation of the physical reset control element. 
     
     
         10 . The household appliance of  claim 1 , further comprising a memory device coupled to the physical reset control element, the memory device being configured to store the at least one operating parameter with each modification which it undergoes. 
     
     
         11 . The household appliance of  claim 10 , wherein the at least one operating parameter is at least one current period of time. 
     
     
         12 . The household appliance of  claim 10 , wherein the memory device is configured to automatically erase storage of the most recently made modification, when the at least one operating parameter has not been changed by the modification. 
     
     
         13 . The household appliance of  claim 1 , further comprising a cooking device with a cooktop. 
     
     
         14 . The household appliance of  claim 1 , wherein the operating parameter is selected from the group consisting of adjustment of a heat setting, adjustment of a zone addition, adjustment of a heat boost and adjustment of a timer time. 
     
     
         15 . The household appliance of  claim 1 , wherein the operating parameter is selected from the group consisting of activation of a timer, activation of a roasting sensor system, activation of an automatic program system, activation of a selection/menu button, activation of a child lock, activation of a wipe protection and activation of a hotplate by actuating a main switch. 
     
     
         16 . The household appliance of  claim 1 , wherein the at least one physical control element is a control panel of a sensor array and the physical reset control element is a control area of the sensor array. 
     
     
         17 . A method for operating a domestic appliance, comprising:
 receiving, via at least one physical control element, a sequence of two or more inputs to modify at least one operating parameter of the domestic appliance;   receiving a reset input via a physical reset control element; and   resetting, within a predefined period of time, at least one most recently made modification from a sequence of recently made modifications,   wherein the at least one most recently made modification is carried out within the predefined period of time.   
     
     
         18 . The method of  claim 17 , wherein the most recently made modification is resettable at least during normal operation. 
     
     
         19 . A household appliance, comprising:
 a cooking device;   at least one physical control element operable to input a sequence of a plurality of modifications, each of which modify at least one operating parameter of the cooking device; and   a physical reset control element configured to reset, within a predefined period of time, at least one most recently made modification from a sequence of recently made modifications,   wherein the at least one most recently made modification is carried out within the predefined period of time.
