Motor driven appliance
First Claim
1. A motor driven appliance comprising:
- a battery;
a motor driven by electric power of the battery;
at least one switch comprising an trigger switch for driving the motor, the trigger switch operating a driving switch and a power switch to thereby control output of battery voltage from the battery;
a control unit configured to control driving of the motor by controlling power supply from the battery to the motor when the trigger switch is turned on;
an abnormality detection unit configured to detect an abnormality of the motor driven appliance;
a determination unit configured, when an abnormality is detected by the abnormality detection unit, to perform an abnormality type determination process of determining whether the abnormality is a first type abnormality or a second type abnormality, the first type abnormality being an abnormality, a state of which detected by the abnormality detection unit is cleared when the trigger switch is switched from on to off, and the second type abnormality being an abnormality, a state of which detected by the abnormality detection unit is not cleared just because the trigger switch is switched from on to off; and
a processing unit configured to perform a process when it is determined that the abnormality detected by the abnormality detection unit is the second type abnormality by the determination unit, and not to perform the process when it is determined that the detected abnormality is the first type abnormality.

Abstract
A motor driven appliance comprises a battery, a motor, at least one switch, a control unit, an abnormality detection unit, a determination unit, and a processing unit. The at least one switch comprises an operation switch. The control unit controls driving of the motor by controlling power supply from the battery to the motor when the operation switch is turned on. The abnormality detection unit detects abnormality of the appliance. The determination unit determines whether the detected abnormality is a first type abnormality that can be cleared when the operation switch is switched from on to off, or is a second type abnormality that cannot be cleared even if the operation switch is merely switched from on to off. The processing unit is configured to perform a specific process when it is determined that the detected abnormality is the second type abnormality.
