Abstract: A motor in a dust collector is cooled. The dust collector includes a body housing, a motor located inside the body housing, a cooling fan rotatable by the motor to feed a gas to around the motor and to discharge the gas from around the motor, and a support including a channel through which the gas is flown by the cooling fan. The support supports the motor.

Abstract: An upright vacuum cleaner includes a main-body part (10) having a dust-collection chamber (14) fluidly connected to a motor chamber (13) via a coupling pipe (15). A fan (13f) and a motor (13m) are housed in the motor chamber. A cleaner head (20) is pivotably and fluidly connected to the main-body part and suctions air through a suction opening (23) when a suction force is generated by the fan and the motor in the motor chamber. A straight suction passageway (24) extends through a central portion of the interior of the cleaner head in plan view. One or more batteries (50) is/are disposed within the cleaner head spaced apart (outward) from the suction passageway in the plan view.

Abstract: A backpack dust collector includes a housing, a slit portion, and a noise-absorbing member. The housing includes a suction port, a dust collecting chamber, a motor chamber, and an exhaust port. The dust collecting chamber is connected to the suction port and configured to accommodate a dust collecting bag. The motor chamber is connected to the dust collecting chamber and accommodates a fan and a motor. Through the exhaust port, air from the motor chamber is discharged. The slit portion is disposed in a flow path between the motor chamber and the exhaust port and includes at least one slit-shaped vent through which air from the motor chamber passes. The noise-absorbing member is disposed in at least part of a flow path between the vent and the exhaust port.

Abstract: A dust collector includes a dust-collector main body, a coupling-hose part, an operation unit, and a belt or harness. The dust-collector main body serves to collect dust by generating a suction draft (partial vacuum). The dust-collector main body includes a housing, a motor, a dust-collection chamber, and at least one battery pack mount. The belt or harness is attached to the dust-collector main body and is designed for the user to carry the dust-collector main body on his or her back. The operation unit is connected to the dust-collector main body via an external, flexible cord. The operation unit includes one or more LEDs for illuminating the area to be cleaned and an ON/OFF switch for controlling operation of the motor.

Abstract: A motor housing of housings forming an outer casing of a tool main body is provided with two battery attachment portions allowing attachment of rechargeable batteries. The two battery attachment portions are configured as slide attachment type battery attachment portions. The two battery attachment portions are suited to slide attachment type rechargeable batteries that are attached through sliding. The two rechargeable batteries are attached in the right-left direction of the tool main body so that the two rechargeable batteries can be arranged side by side in the direction in which the tool main body extends.
