Furthermore, even after cleaning, the mesh filter 46 was clogged with finely ground powder of coffee beans, making cleaning very difficult. Furthermore, in FIG. 6, the coffee beans that have been ground to a predetermined precision in the grinding section 41 are sequentially passed through a perforated plate 47 by centrifugal force and sent into the extraction section 42, and a paper filter is used to extract the coffee liquid. However, the fine powder of coffee beans adheres to the grinding unit 41 and the inner surface of its lid due to static electricity, and does not contribute to coffee extraction. There was a problem in that it was also necessary to wash the fine powder of the beans.

The present invention solves the above-mentioned problems, and aims to provide an electric coffee boiler that is easy to operate, brews clear and delicious coffee, and is easier to clean up afterwards.

Means for Solving the Problems In order to solve the above problems, the electric coffee boiler of the present invention includes a grinding chamber incorporating a cutter for grinding coffee beans, and a grinding chamber that communicates with the grinding chamber at the bottom to grind coffee beans. a hopper-shaped storage chamber for storing the lagoon, a motor for driving the cutter, a hot water supply means for supplying the lagoon, a discharge port for discharging the lagoon sent from the hot water supply means into the inside of the storage chamber, and a crushing chamber. A brewing chamber located below and communicating with the grinding chamber through a perforated plate to extract coffee liquid, and a container for storing the coffee liquid, and located at a position striking the front surface of the discharge port facing inside the storage chamber. , a flexible member with a fixed upper end is installed.

Effect: With the above configuration, the fine powder of coffee beans adhering to the grinding chamber etc. during coffee bean grinding is discharged from the hot water supply means during extraction, and is diffused into the storage chamber, passes through the grinding chamber, and is supplied with hot water to the extraction chamber. As a result, all of the adhering fine powder of coffee beans is washed away, making it easy to clean up after use and reducing the amount of unextracted coffee powder.
