WASHING MACHINE
Document Type and Number:
Japanese Patent JP3162527
Kind Code:
B2
Abstract:
PURPOSE: To precisely perform the judgment of the time requiring a tank washing and its notification even when a service interruption is generated, or a power source plug is removed from a plug socket.
CONSTITUTION: The execution frequency of washing operation is integrated by a microcomputer 27, the integrated washing operation frequency is stored in a nonvolatile memory 35, and when the washing operation frequency stored in the nonvolatile memory 35 reaches a set value 30, a buzzer 34 is driven to notify an user of the execution of a tank washing course for washing a tank. Since the washing operation frequency is thus not cleared even when a service interruption is generated, or a power source plug is removed from a plug socket, the judgment of the time requiring tank washing and its notification can precisely be performed.
