ABSTRACT:
A drip-type hot water feeder of a coffee maker incudes an electric heater for heating and boiling water fed from a water reservoir, and a timer for controlling the time for supplying an electric current to the heater to regulate the hot-water supply to a brewer. The timer has a manually movable control member for continuously variably setting the current supply time and a scale indicating the quantity of hot-water supply corresponding to the time set by the control member. Each mark of the scale has a predetermined width in the setting movement direction of the control member and includes a plurality of compensating indexes indicative of the adjustment of the control member necessary to compensate the set current supply time and thus the quantity of hot water to be supplied indicated by each mark for variations in cold water conditions influencing the time required for supplying a desired quantity of a hot water. The compensating indexes for each mark include a high-temperature index standard index and low-temperature index arranged successively in the direction of setting movement.
