PURPOSE:To keep a temperature of dripping water uniform and to thoroughly extract a coffee element by detecting a temperature of dripping water, and controlling a heating body for heating the dripping water in accordance with its information. CONSTITUTION:On a discharge port 5, a water temperature detecting means 13 such as a thermistor and a thermometer, etc., is provided, and on a water feeding passage 3, a suitable heating body 14 for heating water is provided, and this heating body 14 adjusts an input value and an energizing cycle, etc., by a heating control means 15. Information from the water temperature detecting means 13 is processed by a water temperature detecting circuit 16, sent to a heating body control means 15 and controls the heating body 14. When a water temperature of dripping water heated by the heating body 14 does not rise to the extent that wettability to coffee powder 6 is made satisfactory enough due to a fact that a temperature of water put into a water container 2 is too low, the information from the water temperature detecting means 13 works so as to increase the input value of the heating body 14 or to extend the energizing cycle, and when a temperature of dripping water is high, said information works on its reverse direction. |
