Embodiment approach 1

[0033] Below, according to Figure 1 to Figure 10 , the electric working machine according to Embodiment 1 of the present invention will be described. The electric working machine according to the present embodiment is a dust collector 10 that sucks machining chips and the like generated when an object is machined using a tool. Here, the front, rear, left, right, and up and down shown in the drawings correspond to the front, back, left, and right, and up and down of the dust collector 10 .

[0034]

[0035] Such as figure 1 As shown, the dust collector 10 is composed of a dust collector main body 12 and a suction hose 13 connected to a dust collection port 12h of the dust collector main body 12 . The dust collector main body 12 is constituted as a motor 14 (refer to Figure 6 The circuit diagram of ) rotates a fan (not shown in the figure) to generate an air flow, whereby outside air can be sucked from the dust collection port 12h via the suction hose 13 . And the dust c...

Abstract

The objective of the invention is to produce an electronic power equipment which can be driven by AC and DC power sources. An electronic power equipment, which is configured to be connected to both an AC power source and a DC power source, has a motor 14 configured to be driven by both AC power and DC power, an motor driving AC circuit 30 for supplying AC electric power to the motor 14, a motor driving DC circuit 40 for supplying DC electric power to the motor 14, switching parts RL1-RL12 for switching between the motor driving AC circuit 30 and the motor driving DC circuit 40 wherein the AC and DC circuits are insulated relative to each other, and a controller A1 configured to control the switching parts RL1-RL12, the motor driving AC circuit 30, and the motor driving DC circuit 40.

Description

technical field [0001] The present invention relates to an electric working machine configured to be connectable to an AC power source and a DC power source. Background technique [0002] Patent Document 1 describes an electric working machine related to this. The above-mentioned electric working machine is an AC / DC type dust collector, and includes a DC motor as a drive source. In addition, the AC power supplied from the outlet is converted into DC power by an AC / DC converter, and then supplied to the DC motor. Moreover, it is also comprised so that the DC electric power supplied by the battery can be supplied to the said DC motor via a DC / DC converter. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-160235 [0004] The said AC / DC type dust collector is equipped with the AC / DC converter etc. which convert AC power into DC power. Generally, since an AC / DC converter includes an insulation transformer inside, the size of the dust collector equipped with the ...
