Claims

[Scope of utility model registration request]

In a device that extracts coffee by dropping ground coffee beans with a cutter rotated by a motor into a filter below and dropping hot water heated by a heater onto the coffee beans, the motor 1 is not energized. A power control element 25 to control and a power control element 2 to control energization to the heater 11
4 and a motor rotation detection section 26 for detecting the rotation speed of the motor 1. Furthermore, upon receiving a signal from the motor rotation detection section 26, the end of grinding of coffee beans is detected, and the power control element 25 is operated to transmit power to the motor 1. An electric coffee brewer characterized in that it is provided with a control circuit element 22 that stops energization and operates a power control element 24 to energize the heater 11.
