According to the above configuration, the following effects can be achieved. That is, when a desired amount of coffee beans is put into the hopper 15, a certain amount of the coffee beans fall into the container 4 and are stacked up to the end of the open cylindrical portion 16 of the hopper 15. Next, place the lid 19 and turn on the start switch 24.
A rotary blade 8 is driven by an electric motor 10 to crush coffee beans. The ground coffee beans are pushed upward along the inner wall of the container by the effect of centrifugal wind generated by the rotary blade 8, and suitable ground coffee beans corresponding to the holes in the filter 6 are discharged from the discharge port 7 together with air. At the same time, the coffee beans in the hopper 15 repeatedly fall into the container 4 and are crushed by the rotary blade 8. The cover 19 corresponds to the amount of air discharged from the discharge port 7.
Air flows in through the intake hole 18 of the hopper 15 and is introduced into the container 4 through the open cylindrical portion 16 of the hopper 15, the coffee beans, and gaps between the coffee beans. Furthermore Hopper 15
When coffee beans fall into the container 4 from inside, they may hit near the center of the rotary blade 8 and be scattered upwards, but even in that case, the coffee beans will hit the coffee bean collision wall 20 provided on the lid 19 and be thrown again. , it is thrown into the open cylinder part 16 of the hopper 15 with great force and falls into the container 4. Coarse-grained coffee beans that do not pass through the filter section 6 collide with the hopper 15 and fall toward the bottom of the container 4 from the center where the centrifugal wind force is weak, and are crushed again by the rotary blade 8 to become fine particles. As described above, it is discharged from the discharge port 7.

According to this invention, regardless of the amount of coffee beans input, a constant amount can be reliably supplied into the grinding container, so the load on the electric motor is stable, the grinding time of the rotary blade is stable, and the discharge port This results in a more uniform pulverized particle size being discharged. Furthermore, since the lid is provided with a coffee bean colliding wall, the coffee beans scattered into the hopper by the rotary blade can be returned to the rotary blade side again, and pulverization is very reliable. Furthermore, due to the effect of centrifugal wind during crushing, the fine powder does not adhere closely to the component parts, saving the effort of cleaning, shortening the crushing time, producing low crushing noise, and providing an inexpensive electric coffee mill with a small number of parts. It is.
