The water (,) is heated and supplied to the brewing unit (,) for extraction. After the extraction process, the hot beverage (,) flows into a container (,). The machine for preparing hot beverages includes a device (,) for sensing the amount of water and ingredients. The device (,) sends corresponding electric signals to an electronic evaluation device (,). The electronic evaluation device (,) indicates the detected strength of the hot beverage on an indicator instrument (,). The degree of strength may be varied by this arrangement in conformity with a user's taste. Further, only that amount of ingredients required for the desired strength of the beverage is used.

Machine for preparing hot beverages

A bread toaster comprising a comparator circuit with a sensor responsive to infrared radiation to determine the toasting time of an object to be toasted is extended by a control circuit. The latter detects automatically, whether the bread toaster is used for toasting an object to be toasted that is introduced through a loading and unloading opening into its toasting chamber (toasting operation) or for warming up a respective item which is placed on top of the loading and unloading opening (warming-up operation). The control circuit controls during the toasting operation the operating time of the bread toaster in dependence upon the toasting degree adjusted by the user, while it puts the bread toaster into operation for a fixed period of time during the warming-up operation.
