Document Type and Number:
Japanese Patent JPH0779904
Kind Code:
B2
Abstract:
PURPOSE:To contrive the selection of an unexpected inspection mode to be hardly generated even if switch operations for an inspection mode are simple combination of existing switch operations, by contriving the operations not to be set in the inspection mode when the operation frequency of a specific switch exceeds a fixed frequency. CONSTITUTION:To the center of a micro-computer 1, the load 2 of a washing motor, a drain valve driving solenoid, and the like, a power-supply circuit 3, a reset circuit 4, a line voltage level detecting circuit 5, a display LED 6, a key input circuit 7, an EEPROM 8, and the like are connected. The EEPROM 8 is a PROM for enabling rewriting to be electrically performed, and is a nonvolatile memory. Writing informations by switch operation are retained in the memory, and by the combination of ready-set switch operations for a washing process, washing condition setting, and the like, a washing machine to be set in an inspection mode is use. Then, its controller is contrived so that specific switch operation frequency kept stored cannot be set in the inspection mode when its frequency exceeds a fixed frequency.
