Abstract
A vacuum cleaner to suction dust by applying vibration includes a motor, an eccentric load applied to a rotating shaft of the motor which when rotated by a rotation of the rotating shaft produces vibration force, a vibration plate to apply the vibration force to an object to be cleaned, and a vibration transfer member to transfer vibration force to the vibration plate.
Claims15
A vacuum cleaner to suction dust by applying vibration, the vacuum cleaner comprising:
- a body;
- a fan motor provided in the body to suction dust;
- a suction nozzle part at a portion of the body;
- a motor in the body, the motor including a rotating shaft;
- an eccentric load at the rotating shaft of the motor, which when rotated by a rotation of the rotating shaft, a vibration force is produced by a vibration of the motor;
- at least one vibration plate located at the suction nozzle part to apply the vibration force to an object to be cleaned;
- and
- a vibration transfer member to transfer the vibration force to the at least one vibration plate,
- wherein the vibration transfer member comprises:
- a motor accommodation portion which accommodates the motor and is provided with at least one hinge pivot;
- and
- at least one connection member to connect the motor accommodation portion to the at least one vibration plate, wherein the at least one connection member is rotatably connected to the at least one hinge pivot;
- wherein the at least one hinge pivot is eccentrically positioned forward or rearward of the rotating shaft of the motor in a horizontal direction of the rotating shaft.

A vacuum cleaner to suction dust by applying vibration, the vacuum cleaner comprising:
- a body;
- a fan motor provided in the body to suction dust;
- a suction nozzle part provided at a portion of the body to suction dust by applying vibration to an object, wherein the suction nozzle part comprises a suction port;
- a vibration system comprising a motor and an eccentric load applied to a rotating shaft of the motor where a vibration is produced by a vibration of the motor when the eccentric load is rotated by a rotation of the rotating shaft;
- two vibration plates located at the suction nozzle part to apply the vibration to the object and individually provided to front and back of the suction port;
- and
- at least one elastic member,
- wherein the vibration system is elastically supported by the body with respect to a direction of vibration of the vibration plate by the at least one elastic member,
- the vibration system comprising:
- a motor accommodation portion which accommodates the motor;
- at least one hinge pivot provided to the motor accommodation portion;
- and
- at least one connection member to connect the motor accommodation portion to the two vibration plates individually, wherein the at least one connection member extends from one side of the at least one hinge pivot and another connection member extends from another side of the at least one hinge pivot.
