Power tool

摘要

The present invention provides a power tool that can be used at a position away from the external power source. The power tool includes a housing, a motor, an end tool, a battery pack, and an inverter. The housing has an upper side portion and a lower side portion. The motor is supported by the housing and driven by alternate-current power. The end tool is supported by the housing and rotatably driven by the motor. The battery pack outputs direct-current voltage. The inverter is disposed on the upper side portion and at a position higher than the motor and configured to convert the direct-current voltage outputted from the battery pack into alternate-current voltage and to supply the motor with alternate-current power.

主权项

1. A power tool comprising:
a housing having an upper side portion, a lower side portion, a front part, and a rear part; a first direction being oriented from the lower side portion towards the upper side portion; a second direction being oriented from the rear part towards the front part, perpendicular to the first direction, and parallel to a traveling direction of the power tool; an alternating-current (AC) motor supported by the housing and driven by alternating-current power; an end tool supported by the housing and rotatably driven by the AC motor; a battery pack that outputs direct-current voltage; an inverter casing attachable to and detachable from the upper side portion, the inverter casing including a mount section, the battery pack being attachable to and detachable from the mount section; an inverter accommodated in the inverter casing and configured to convert the direct-current voltage outputted from the battery pack into AC voltage and to supply the AC motor with AC power when the inverter casing is attached to the upper side portion so that the upper side portion is disposed between the inverter casing and the AC motor relative to the first direction; and an AC power input selectively connectable to an extension cord connected to an external AC power source to supply AC power received from the extension cord to the AC motor for operation of the power tool when the inverter casing is detached from the upper side portion.
