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.

First claim

What is claimed is:

1. 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.

2. The vacuum cleaner according to claim 1 , wherein 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.

3. The vacuum cleaner according to claim 2 , wherein one side of the one connection member is rotatably connected to the at least one hinge pivot and other side of the one connection member is connected to one vibration plate, and one side of the another connection member is rotatably connected to the at least one hinge pivot and other side of the another connection member is connected to another vibration plate.

4. The vacuum cleaner according to claim 1 , wherein the at least one hinge pivot is arranged at a lower portion of the rotating shaft of the motor and spaced apart from the rotating shaft.

5. The vacuum cleaner according to claim 1 , wherein the at least one hinge pivot comprises two hinge pivots, a hinge pivot provided on either side of the motor, and the at least one connection member is provided to each of the hinge pivot.

6. The vacuum cleaner according to claim 5 , wherein the two hinge pivots are coaxially arranged and separate vibration plates are provided at either side of each of the hinge pivots and connected to a corresponding one of the at least one connection member.

7. The vacuum cleaner according to claim 1 , further comprising at least one elastic member, wherein the motor, the at least one vibration plate and the at least one connection member are elastically supported by the body through the at least one elastic member.

8. The vacuum cleaner according to claim 7 , wherein the at least one elastic member is arranged between the at least one connection member and the body and fixed, and amplitude of vertical vibration of the at least one vibration plate is restricted by elastic force of the at least one elastic member.

9. 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.

10. The vacuum cleaner according to claim 9 , wherein the one connection member connects to one vibration plate through one elastic member and the another connection member connects to another vibration plate through another elastic member.

11. The vacuum cleaner according to claim 10 , wherein the at least one hinge pivot comprises two hinge pivots, a hinge pivot provided on either side of the motor accommodation portion, the two vibration plates are arranged at front and rear sides of the motor accommodation portion and connected to the respective connection members.

12. The vacuum cleaner according to claim 9 , further comprising at least one hinge pivot fixing member to fix the at least one hinge pivot to the body.

13. The vacuum cleaner according to claim 9 , wherein the motor accommodation portion comprises:
a motor seating portion;
a spacing member to space the hinge pivot apart from the motor seating portion; and
a motor accommodation portion cover joined to the spacing member to cover the motor seating portion and spaced apart from the motor seating portion.

14. The vacuum cleaner according to claim 9 , further comprising a handle allowing a user to apply force thereto to manipulate the vacuum cleaner, the handle at one end of the body opposing the suction nozzle part at an other end of the body, wherein the body is inclined at an angle with respect to the suction nozzle part.

15. The vacuum cleaner according to claim 9 , wherein the motor is positioned to be over the suction port and a longitudinal direction of the motor is parallel to the suction port.
