Abstract

A dust collector has a well-balanced weight. The dust collector includes a body housing, a motor located inside the body housing, a fan rotatable by the motor, and a battery mount located inside the body housing and frontward from the motor.

Claims (49)

1. A dust collector that is configured to receive a first battery pack and a second battery pack in a detachable manner, the dust collector comprising:

a motor having a rotation axis in a vertical direction; and

a body housing (i) containing the motor and (ii) including:

a first battery compartment (i) frontward from the motor in a front-rear direction perpendicular to the vertical direction and leftward from the motor in a left-right direction perpendicular to the vertical and front-rear directions, (ii) having a first body opening facing frontward, and (iii) including a first battery mount configured to guide the first battery pack in the front-rear direction as the first battery pack is attached to and detached from the first battery mount through the first body opening;

a second battery compartment (i) frontward and rightward from the motor, (ii) having a second body opening facing frontward, and (iii) including a second battery mount configured to guide the second battery pack in the front-rear direction as the second battery pack is attached to and detached from the second battery mount through the second body opening;

a battery cover (i) supported on the body housing in a vertically pivotable manner and (ii) including:

a cover portion including a first cover portion configured to cover the first body opening and a second cover portion configured to cover the second body opening; and

a cover opening; and

a switch base (i) between the first body opening and the second body opening in the left-right direction, (ii) bearing a main power switch and (iii) configured to be exposed through the cover opening when the battery cover is closed,

wherein an entirety of the switch base is directly between the first battery compartment and the second battery compartment in the left-right direction.

2. The dust collector according to claim 1 , wherein

the first battery mount and the second battery mount each has a center frontward from a center of the body housing in the front-rear direction.

3. The dust collector according to claim 1 , wherein

the motor, the first battery mount and the second battery mount do not overlap each other in the front-rear direction and the left-right direction.

4. The dust collector according to claim 1 , wherein

the switch base includes a suction force adjustment switch located above or below the main power switch.

5. The dust collector according to claim 1 , further comprising:

an adapter mount at a top of the body housing.

6. The dust collector according to claim 1 , further comprising:

a tank unit supporting the body housing, the tank unit having a suction port in a front of the tank unit.

7. The dust collector according to claim 6 , further comprising:

casters supporting the tank unit in a movable manner,

wherein the tank unit supporting the body housing is movable in a front-rear direction on the casters.

8. The dust collector according to claim 6 , further comprising:

a fan rotatable about the motor, the fan including

a blowing fan configured to generate a suction force at the suction port, and

a cooling fan configured to generate an airflow to cool the motor.

9. The dust collector according to claim 8 , further comprising:

a fan cover having a fan inlet, the fan cover covering at least a part of the blowing fan,

wherein the tank unit includes

a tank configured to store liquid sucked in through the suction port, and

a float in an internal space of the tank, the float being movable with the liquid to close a flow channel communicating with the fan inlet.

10. A dust collector that is configured to receive a first battery pack and a second battery pack in a detachable manner, the dust collector comprising:

a motor having a rotation axis in a vertical direction; and

a body housing (i) containing the motor and (ii) including:

a first battery compartment (i) frontward from the motor in a front-rear direction perpendicular to the vertical direction and leftward from the motor in a left-right direction perpendicular to the vertical and front-rear directions, (ii) having a first body opening facing frontward, and (iii) including a first battery mount configured to guide the first battery pack in the front-rear direction as the first battery pack is attached and detached from the first battery mount through the first body opening;

a second battery compartment (i) frontward and rightward from the motor, (ii) having a second body opening facing frontward, and (iii) including a second battery mount configured to guide the second battery pack in the front-rear direction as the second battery pack is attached to and detached from the second battery mount through the second body opening; and

a switch base (i) between the first body opening and the second body opening in the right-left direction, (ii) bearing a main switch and (iii) configured to be exposed through the cover opening when the battery cover is closed,

wherein the motor, the first battery mount and the second battery mount do not overlap each other in the front-rear direction and the left-right direction.

11. A dust collector that is configured to receive a first battery pack and a second battery pack in a detachable manner, the dust collector comprising:

a motor having a rotation axis in a vertical direction; and

a body housing (i) containing the motor and (ii) including:

a first battery compartment (i) frontward from the motor in a front-rear direction perpendicular to the vertical direction and leftward from the motor in a left-right direction perpendicular to the vertical and front-rear directions, (ii) having a first body opening facing frontward, and (iii) including a first battery mount configured to guide the first battery pack in the front-rear direction as the first battery pack is attached and detached from the first battery mount through the first body opening;

a second battery compartment (i) frontward and rightward from the motor, (ii) having a second body opening facing frontward, and (iii) including a second battery mount configured to guide the second battery pack in the front-rear direction as the second battery pack is attached to and detached from the second battery mount through the second body opening;

a battery cover (i) supported on the body housing in a vertically pivotable manner and (ii) configured to cover the first body opening and the second body opening;

a switch base (i) between the first body opening and the second body opening in the left-right direction, (ii) bearing a main power switch and (iii) configured to be exposed through the cover opening when the battery cover is closed; and

an adapter mount at a top surface of the body housing.

12. The dust collector according to claim 11 , wherein

the adapter mount is a connector to which a tool storage box is connectable.
