SAFETY DEVICE FOR AN ELECTRIC HEATING APPLIANCE SAFETY DEVICE FOR AN ELECTRIC HEATING APPLIANCE

摘要

An automatic shut-off and indication device for an electric heating appliance is provided which includes:a sensor (2) for sensing usage of the appliance and for providing a usage-signal (US) indicating a non-usage of the appliance;a switch (10) for off-switching a heater (12) of the appliance in response to a switching signal (SS) derived from the usage-signal (US);a sensor (4) for sensing orientation of the appliance and for providing an orientation signal (OS) for indicating different orientations of the appliance;a selector (18) for activating an indicator (22) in response to the switching signal (SS), the indicator (22) signaling the off-switching of the heater (12); andan indication timer (8) for providing a time delay between off-switching the heater (12) and activating the indicator (22), which time delay is dependent on the orientation signal (OS).The shut-off of the heater (12) is signalled to the user by the indicator (22). A different time-delay between shut-off and indication depending on the orientation of the appliance provides the possibility to postpone the indication when the appliance is shut off in a regular rest position, for instance the heel rest position of an electric pressing iron.
