Abstract

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.

Claims (17)

1. A coffee machine including a grinder configured to grind coffee beans, and a chute configured to discharge ground beans ground by the grinder, the coffee machine comprising:

a pivotable hammer; and

a first holding member, wherein

the hammer includes a striking member that abuts against the chute by an elastic force in an initial state, and a second holding member that sandwiches and holds a cup accommodating the ground beans discharged from the chute 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 a 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.

2. The coffee machine according to claim 1 , wherein

at least one of the first holding member and the second holding member includes an anti-slip portion.

3. The coffee machine according to claim 1 , wherein

one of the first holding member and the second holding member is in contact with the peripheral wall at one position from an inner side of the peripheral wall, and

the other of the first holding member and the second holding member with respect to the one holding member is in contact with the peripheral wall at two positions from an outer side of the peripheral wall.

4. The coffee machine according to claim 3 , wherein

the first holding member is fixedly disposed and corresponds to the other holding member, and

the second holding member corresponds to the one holding member.

5. The coffee machine according to, wherein

the hammer includes an operation portion that is operated when the hammer shifts from the initial state to the striking preparation state, and

the operation portion is located on a right hand side of an operator.
