VACCUM CLEANER

摘要

A vacuum cleaner including a wheel, a driving motor configured to provide the wheel with a driving force, and a clutch configured to connect transfer gears to the wheel or to cancel a connection between the transfer gears and the wheel. A body of the vacuum cleaner is able to actively travel because of the transfer gears are connected to the wheel when power is applied to the driving motor and the wheel smoothly rotates without having a detent torque of the driving motor when power is not applied to the driving motor. The wheel is provided with an internal gear, and one of the transfer gears is configured to transfer the driving force of the driving motor by making contact with the internal gear.

1. A vacuum cleaner comprising:
a wheel; a driving motor configured to provide the wheel with a driving force; transfer gears provided to be engaged with each other between the driving motor and the wheel; and a clutch disposed between the wheel and one of the transfer gears most adjacent to the wheel, the clutch being configured to connect the transfer gears to the wheel such that the driving force of the driving motor is transferred to the wheel or to disconnect the transfer gears from the wheel to prevent a detent torque of the driving motor and a rolling friction of the transfer gears from being transferred to the wheel while preventing noise due to the detent torque and the rolling friction from occurring.
