A coffee machine including a grinder configured to grind coffee beans, and a coffee machine made to return a grinder falling into an abnormal state to a normal state. The grinder configured to grind the coffee beans by a predetermined rotation operation in the normal state, and an operation portion are provided, when the grinder is in the abnormal state (bean clogging state) in which the predetermined rotation operation cannot be performed, if the operation portion is operated, the reverse rotation operation is executed in a direction opposite to that of the predetermined rotation operation, and in the normal state, the reverse rotation operation is not executed even if the operation portion is operated.
1. A coffee machine, comprising:
a grinder configured to grind coffee beans by a predetermined rotation operation in a normal state; and
an operation portion, wherein
when the grinder is in an abnormal state in which the predetermined rotation operation cannot be performed, if the operation portion is operated, a reverse rotation operation is executed in a direction opposite to that of the predetermined rotation operation, and in the normal state, the reverse rotation operation is not executed even if the operation portion is operated.
2. The coffee machine according to claim 1 , further comprising:
a mode shift control unit configured to control mode shift of the machine, wherein
the mode shift control unit shifts to one mode of a plurality of types of modes, and
even when the abnormal state occurs in any one of the plurality of modes, the grinder executes the reverse rotation operation if the operation portion is operated.
3. The coffee machine according to claim 2 , wherein
the plurality of types of modes include a normal mode in which waste is allowed to be separated from ground beans ground by the grinder, and
a cupping mode in which the waste is not separated from the ground beans ground by the grinder.
4. The coffee machine according to claim 2 , wherein
when the grinder returns from the abnormal state to the normal state, the mode shift control unit maintains the mode before the grinder enters the abnormal state.
5. The coffee machine according to claim 1 , wherein
the grinder stops a rotation operation when the state does not return to the normal state even after repeating the reverse rotation operation a predetermined number of times in the abnormal state.
