PURPOSE:To obtain an optimal hot water supply state for supplying tea hot water being delicious and the most easily drinkable by providing a fuzzy inference processor, and an output device for controlling an immersion control valve from an immersion time limit time operated by the fuzzy inference processor. CONSTITUTION:A fuzzy inference processor 16 executes a fuzzy logical operation and operates an immersion time limit time, based on information integrated by an integrating device 14 and a control rule fetched from a memory device 15. An output device 17 controls an immersion control valve 10 from the immersion time limit time operated by the fuzzy inference processor 16. Accordingly, in this embodiment, since the passing hot water quantity, and a variation of the elapsed time are used as control parameters, a delicate control can be executed. Also, since the control rule consists of the rule of thumb of a person, an automatic tea feeder 1 can be controlled by opening and closing the immersion control valve 10 at an optimal immersion time limit time. |
