indication device to delay the activation of the indication
device a time-delayed period after switching off the heater
for the appliance.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. An automatic shut-off and indication device for an
electric heating appliance comprising:
means (2) for sensing usage of the appliance and for
providing a usage-signal (US) indicating a non-usage of
the appliance;
means (10) for off-switching a heater (12) of the
appliance in response to a switching signal (SS) derived
from the usage-signal (US);
means (4) for sensing orientation of the appliance and
for providing an orientation signal (OS) for indicating
different orientations of the appliance;
means (18) for activating an indicator (22) in response
to the switching signal (SS), the indicator (22)
signalling [sic, signaling] the off-switching of the
heater (12), including means (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).
