| 摘要 |
<p>The invention relates to an electric shaver (1) comprising a cutter unit (3), an electric motor (4) arranged to drive the cutter unit (3), a load detector (14) arranged to measure at least one electric parameter indicative of a power consumption of the motor (4) to obtain a measured value. An idle load calculator (16) receives one or more of the measured values measured at different instances during an idle period of the shaver. The idle load calculator calculates an idle load value using the one or more measured values, and stores the calculated idle load value in a memory (17). A threshold calculator (18) determines a cleaning threshold value. A comparator (19) generates a cleaning signal if an idle load value for the current shaving session exceeds the cleaning threshold value. An alerter (8) receiving the cleaning signal produces an alert indicating to a user that the cutter unit of the shaver should be cleaned.</p> |
