ABSTRACT:
An electric toaster comprises an infrared detector (6) directed toward a heating device for the toaster, and a control device for the supply of electricity to the heating elements which is subordinated to a device (10) for measuring the radiation received by the detector, and which comprises a device (12) for processing the signal emitted by the detector. A comparator (13) compares a signal (S) leaving the processing device (12) with a signal (N) emitted by an adjustment device (14) of the degree of toasting. The measuring device (10) comprises, between the processing device (12) and the comparator device (13), a device (16) for diverting the signal (S) whose control is directed by a timer (18) of short duration which re-establishes at the end of that short duration the passage of the signal (S) toward the comparator (13).
