Abstract
In a coffee maker, a hot-water tank, including water purifying agents and a siphon mechanism, is provided between a coffee-extracting room and a hot-water outlet. This structure reduces an amount of water remaining in the purifying agents. A water tank, a heater which heats the water supplied from the water tank and produces hot water, and a hot-water outlet for pouring the hot water supplied from the heater into the coffee-extracting room are provided. The hot-water tank detachable from a main body of the coffee maker is situated between the outlet and the coffee-extracting room. This structure allows a siphon phenomenon to supply intermittently the hot water from the hot-water tank to the coffee-extracting room. After a coffee extraction, the hot-water tank can be detached from a main body of the coffee maker and washed with ease.
