A coffee machine, including a grinder configured to grind coffee beans, and a coffee machine made to remove waste, such as chaff, from a separation area, where the waste such as chaff is separated from ground beans. The coffee machine includes a first grinder configured to grind the coffee beans by grinding, a separation area where the waste is separated from the ground beans ground by the first grinder. And, the waste from the separation area is cleaned by wind pressure while the first grinder is in a stop state.

Coffee machine

A coffee machine including a grinder configured to grind coffee beans, and a coffee machine devised to be able to bring an air volume for separating waste such as chaff as close as possible to a target air volume. A first grinder configured to grind coffee beans; a fan configured to generate a wind pressure by rotating to separate waste from the ground beans ground by the first grinder; a fan motor configured to cause the fan to rotate; and a control unit configured to control rotation of the fan motor according to a set value, and the control unit acquires information (the number of rotation pulses) related to a rotation speed of the actually rotating fan motor, corrects the set value based on the acquired information, and controls the rotation of the fan motor according to the corrected set value.

The present invention relates to a coffee machine equipped with a grinder that grinds coffee beans, and a mechanism that reduces ground beans on an inner peripheral wall of a chute. A hammer includes a striking member that abuts against a chute by an elastic force in an initial state, and a second holding member that sandwiches and holds a cup with the first holding member by the elastic force, and enters a striking preparation state in which the striking member is temporarily separated from the chute by pivoting from the initial state, the second holding member is disposed at a position where a distance from the first holding member is smaller than a thickness of an peripheral wall of the cup in the initial state, and the striking member applies an impact to the chute when the hammer returns from the striking preparation state to the initial state by the elastic force.
