Abstract
An electric shaver provided with at least one cutter unit, a drive unit for driving the at least one cutter unit and a display device for displaying information, wherein the drive unit, when being active, is operable in different operation modes, wherein a mode input element is provided for switching the drive unit into different operation modes.
Claims17
An electric shaver, comprising:
- at least one cutter unit;
- a drive unit having an active state and an inactive state, the active state having a plurality of different operation modes;
- a display device operable in any of a plurality of different display modes, each different display mode corresponding to a displaying of a different set of shaver information;
- a mode input element manually operable by a user to generate mode input signals;
- a controller that receives the mode input signals from the mode input element and controls the drive unit and display device in response to the mode input signals;
- wherein:
- when the drive unit is in the active state:
- the drive unit is controlled by the controller to drive said at least one cutter unit in a current operation mode selected from the plurality of the different operation modes;
- the mode input element is manually operable to generate a corresponding mode input signal causing the controller to switch the current operation mode to another operation mode selected from the plurality of the different operation modes;
- and
- when the drive unit is in the inactive state:
- the mode input element is manually operable to generate a corresponding mode input signal causing the controller to change a current display mode of the display device to another display mode selected from the plurality of different display modes;
- the mode input element is manually operable to generate a corresponding mode input signal that causes the controller to activate an automatic switching mode of the display device;
- and
- when the automatic switching mode is activated, the display device is caused by the processor to sequentially display one set of shaver information for a period of time under control of a timer then after the period of time displays another different set of shaver information.

A method for controlling an electric shaver and a display device connected thereto, said electric shaver comprising:
- at least one cutter unit;
- a drive unit operable to drive said at least one cutter unit, wherein said drive unit, when active, is operable in more than one operation mode;
- and
- a mode input element operable to generate mode input signals to switch the drive unit into different operation modes, and to switch the display device into different display modes;
- and
- a controller that receives the mode input signals from the mode input element and controls the drive unit or the display device in response to the mode input signals,
- the method comprising:
- manually activating the mode input element to switch the operation mode of the drive unit when said drive unit is active;
- and
- manually activating an automatic switching mode of the display, either by activating the mode input element or by switching the electric shaver off, wherein the automatic switching mode of the display, when activated, comprises an automatic switching of the display device into different display modes by a timer to display a plurality of the different sets of the shaver information one after the other.
7 more elements
An electric shaver, comprising:
- at least one cutter unit;
- a drive unit operable to drive said at least one cutter unit in any of a plurality of different operation modes when the drive unit is active;
- a display device operable to display different sets of shaver information;
- a mode input element operable to generate mode input signals;
- and
- a controller that receives the mode input signals from the mode input element and controls the drive unit of the display device in response to the mode input signals,
- wherein:
- said display device is configured to be operable in an automatic switching mode in which ones of the different sets of information are displayed one after the other under control of a timer when the electric shaver is switched off;
- said mode input element comprises at least one push button configured to change a functionality of the mode input unit depending on an ON/OFF status of the drive unit;
- and
- when the ON/OFF status of the drive unit is OFF, the mode input element functions to cause the display device to display one set of the shaver information or to activate the automatic switching mode;
- and
- when the ON/OFF status of the drive unit is ON, the mode input element functions to change the operation mode of the drive unit.
