Abstract
A coffee maker includes a reservoir for accommodating a quantity of water to brew a coffee beverage; a filter basket for accommodating ground coffee to be brewed therein; a water quantity sensor for producing a first signal representing the quantity of water in the reservoir; a coffee quantity sensor for producing a second signal representing the quantity of coffee in the filter basket; and a comparator for comparing a ratio between the first and second signals. The comparator has a first input which is connected to the water quantity sensor and to which the signal is applied; and a second input which is connected to the coffee quantity sensor and to which the second signal is applied. A display device is connected to the comparator for being actuated thereby as a function of the ratio between the first and second signals.
