Abstract
A siphon coffee maker includes a lower container for containing water, an electric heater for applying heat to the lower container, an upper container disposed on the lower container and having a water feed tube communicating to the interior of the lower container, a storage for storing data of an amount of coffee to be extracted, and a microcomputer-based control unit. The control unit operates to energize the heater in response to an extracting operation command, thereby starting an extracting operation. The control unit then operates to energize the heater after completion of the extracting operation by supplying the heater with an electrical output in proportion to the temperature of the amount of coffee to be extracted, data of which is stored in the storage.
