Abstract: An electrically heatable toaster includes at least one bread holder which is held in toasting position by an electromagnet. The electromagnet has a tripping device which is actuated manually as well as electrically by a timing control. The timing control includes a clock pulse actuated counting circuit connected to a frequency-determining charging capacitor and a voltage divider. The voltage divider includes a temperature-dependent resistor for compensating the influence of the toasting degree temperature and for triggering the electromagnet tripping device after a preset degree of toasting is reached. An oscillator with two complementary transistors combined in a programmable unijunction transistor circuit operates the counting circuit. The transistors are connected on the input side to a charging current circuit of the frequency determining capacitor and on the output side through a dividing point of the voltage divider with the temperature-dependent resistance to a clock input of the counting circuit.

Abstract: The invention relates to an electric toaster with toasting time control by means of a timer and a lifting device for the bread carrier. The lifting device consists of at least one spring having the so-called memory effect and operatively connected to the bread carrier.
