Electric device with a user guide
First Claim
1. An electric appliance, comprising:
- a plurality of operating elements, each operating element actuatable by a user in an actuatable state and not actuatable by the user in a non-actuatable state, each operating element including a respective status display device; and
a control logic unit coupled to the operating elements, the control logic unit configured to detect a user input, change an operating state of the electrical appliance according to the user input, and activate the status display device of each operating element that is in an actuatable state and deactivate the status display device of each operating element that is in a non-actuatable state in response to a change in the electrical appliance from a first operating state to a second operating state.

Abstract
An electric device comprising a plurality of operating elements which can be operated by a user. Said device is associated with a status display device, and it also comprises a control logic unit which is coupled to the operating elements in order to detect user operations and which is adjusted. Furthermore, the electric device has an operational state which corresponds to the user operations which are to be adjusted. In a first state, the control logic unit displaces the status display of each operational element, from which it is able to process a user operation, according to an adjusted operational state, and in a second state, said unit displaces the status display of each operational element, whereby it is not possible to process a user operation, according to an adjusted operational state.

12. A refrigerator comprising:
-
a housing having an interior chamber; a door coupled to the housing for opening and closing the interior chamber; a control panel, the control panel including a display window for displaying information and a plurality of buttons for receiving input from a user; each button including a respective light source and a respective proximity sensor, the proximity sensor configured to detect contact of the button by the user; each respective light source being in an illuminated state when the button is actuatable by the user and in a non-illuminated state when the button is not actuatable by the user; and a control logic unit electrically connected to the control panel, the control logic unit configured to control operation of the refrigerator, receive input signals from the buttons, send output signals to control the display window and light sources, adjust an operating state of the refrigerator in response to a user input, and activate the light source of at least a first button into the illuminated state and deactivate the light source of at least a second button into the non-illuminated state in response to the user input. - View Dependent Claims (13, 14, 15, 16, 17)

18. An electric appliance, comprising:
-
a plurality of operating elements, each operating element actuatable by a user in an actuatable state and not actuatable by the user in a non-actuatable state, each operating element including a respective status display device; a control logic unit coupled to the operating elements, the control logic unit configured to detect a user input, change an operating state of the electrical appliance according to the user input, and activate the status display device of each operating element that is in an actuatable state and deactivate the status display device of each operating element that is in a non-actuatable state in response to a change in the electrical appliance from a first operating state to a second operating state, wherein a status display device is in an illuminated state when a respective operating element is in the actuatable state and the status display device is in a non-illuminated state when the respective operating element is in the non-actuatable state, the control logic unit is further configured to switch each status display device that is in the illuminated state into the non-illuminated state after a pre-determined time interval elapses following detection of the user input and the control logic unit is further configured to maintain in the non-illuminated state the status display devices for the operating elements that are in the non-actuatable state, if the user attempts to actuate an operating element in the non-actuatable state; and a housing, the housing including an interior chamber that is closed by a door, wherein the control logic unit is further configured to maintain in the non-illuminated state the status display devices of the operating elements that are in the non-actuatable state, if the door is opened.
