Claims

[Scope of utility model registration request]

a heater 6 that heats the water led from the water tank 1;
A filter basket 13 for storing ground coffee powder, a valve 9 for spouting heated hot water into the basket 13, a water diverter 18 having an overflow port 12 for overflowing the hot water into the water tank 1, and this water diverter. A spouting pipe 7 that connects the vessel 18 and the water tank 1 and spouts the hot water to the water divider 18,
In an electric coffee boiler that drips hot water into the basket 13 via the pipe 7 and the water divider 18 to extract coffee liquid, a connecting pipe 4 is connected between the water tank 1 and the heater 6 and communicates with the spout pipe 7. This pipe 4 is provided with a temperature detection element 5 that detects the temperature rise of the pipe 4 and determines the amount of water in the aquarium 1, and further closes the valve 9 from the beginning of energization of the heater 6, and After a certain temperature is detected by the filter 5, the valve 9 is opened so as to spout the hot water into the filter basket 13, and the water tank 1 is opened.
An electric coffee boiler characterized in that it is equipped with a microcomputer 15 having a function of controlling the power of the heater 6 to suit the heating of the amount of water in the coffee boiler.
