Abstract
Disclosed is a cleaner comprising a cleaner body, a handle provided in the cleaner body, a wheel provided in a lower portion of the cleaner body and rotatably supporting the cleaner body, a motor driving the wheel electrically, an encoder sensing the rotation number of the wheel or the motor, and a controller controlling the driving of the motor by varying the voltage applied to the motor based on the rotation number sensed by the encoder, wherein the controller electrically drives the wheel by applying voltage to the motor when the velocity of the cleaner body initially moving is a preset value or more, and a controlling method for the cleaner.
Claims20
A cleaner comprising:
- a cleaner body;
- a handle provided in the cleaner body;
- a wheel provided in a lower portion of the cleaner body and rotatably supporting the cleaner body;
- a motor driving the wheel electrically;
- an encoder sensing the rotation number of the wheel or the motor;
- and
- a controller controlling the driving of the motor by varying the voltage applied to the motor based on the rotation number sensed by the encoder,
- wherein the controller electrically drives the wheel by applying voltage to the motor when the velocity of the cleaner body initially moving is a preset value or more.
A controlling method for a cleaner comprising:
- initially moving a cleaner body by rotating a wheel rotatably supporting the cleaner body;
- determining whether the moving velocity of the cleaner body reaches a preset value after the initial movement of the cleaner body;
- and
- electrically moving the cleaner body by applying voltage to a motor electrically driving the wheel when the moving velocity of the cleaner reaches the preset value.
