Abstract

An upright cleaner removes dust from a drum brush. The upright cleaner includes a case having a suction port, a drum brush rotatably provided in the case to sweep and guide foreign matter to the suction port, a dust removal unit provided in the case so that the dust removal unit is moved between a first position where one side of the dust removal unit contacts the drum brush and a second position where the side of the dust removal unit is separated from the drum brush, and a lever connected to the dust removal unit to actuate the dust removal unit.

Claims

1. An upright cleaner comprising:

a case having a suction port;

a drum brush rotatably provided in the case to sweep and guide foreign matter to the suction port;

a dust removal unit provided in the case so that the dust removal unit is moved between a first position where a side of the dust removal unit contacts the drum brush and a second position where the side of the dust removal unit is separated from the drum brush; and

a lever connected to the dust removal unit to move the dust removal unit from the second position to the first position.

2. The upright cleaner according to claim 1, wherein the dust removal unit comprises a bar-type body and a dusting part extending from the body so that the dusting part contacts the drum brush at the first position and is separated from the drum brush at the second position.

3. The upright cleaner according to claim 2, wherein

the lever comprises an extension part protruding above the case and a bent part extending from an end of the extension part so that the bent part is bent toward a front of the case, and

the lever is connected to the body.

4. The upright cleaner according to claim 3, further comprising an elastic part provided between the bent part and a top of the case to elastically bias the bent part upward.

5. The upright cleaner according to claim 2, wherein one side of the lever forms an extension part protruding forward from the case, and the other side of the lever is connected to the body.

6. The upright cleaner according to claim 5, wherein the extension part is provided at a lower end thereof with a support part protruding forward from the case, and the upright cleaner further comprises an elastic part provided between the support part and the extension part to elastically bias the extension part upward.

7. The upright cleaner according to claim 5, further comprising an actuating unit coupled to the case to cover the extension part, the actuating unit being configured to be moved between an actuating position at which the extension part is pressed and a releasing position at which the extension part is released.

8. The upright cleaner according to claim 7, wherein the actuating unit comprises a front plate provided at a front of the extension part and an upper plate connected to an upper end of the front plate and bent rearward.

9. The upright cleaner according to claim 8, further comprising a locking unit hingedly coupled to the case above the upper plate, wherein the locking unit locks the upper plate so that the actuating unit is held at the actuating position when the actuating unit is located at the actuating position.

10. The upright cleaner according to claim 9, wherein the locking unit comprises an elastic support part extending downward from a hinge shaft coupled to the case so that a rear of the elastic support is supported at the case, a catching part extending frontward from the hinge shaft so that an end of the catching part protrudes more forward than an end of the support part, and a footstool part extending frontward from the hinge shaft.

11. The upright cleaner according to claim 10, wherein

the upper plate is provided at one end thereof with an insertion groove formed by separation between the upper plate and the case, and

the catching part pushes the upper plate downward to hold the upper plate at the actuating position and is received in the insertion groove at the releasing position.

12. The upright cleaner according to claim 8, further comprising a pressing part provided at an inside of the front plate at a position corresponding to the extension part to press the extension part when the actuating unit is moved to the actuating position.

13. The upright cleaner according to claim 2, wherein the dusting part comprises a brush.

14. The upright cleaner according to claim 2, wherein the dusting part comprises one or more brush bundles arranged at intervals.

15. An upright cleaner having a suction body, a main body and a handle, the upright cleaner comprising:

a case forming an external appearance of the suction body;

a drum brush rotatably provided in the case; and

a dust removal unit movably provided in the case, the dust removal unit performing an actuating operation through which the dust removal unit contacts the drum brush to remove dust from the drum brush and a releasing operation through which the dust removal unit is separated from the drum brush.

16. The upright cleaner according to claim 15, further comprising a lever connected to the dust removal unit to control the dust removal unit to perform the actuating operation or the releasing operation.

17. An upright cleaner comprising:

a main body having a motor and a dust collection device;

a handle extending from the main body, the handle having a manipulation part to drive the motor;

a suction body having a suction port to suction air and a discharge port to supply the suctioned air to the main body;

a drum brush provided in the suction body so that the drum brush is rotated by the motor to sweep and guide foreign matter to the suction port; and

a dust removal unit provided in the suction body so that the dust removal unit is moved between a first position where the dust removal unit contacts the drum brush and a second position where the dust removal unit is separated from the drum brush.

18. The upright cleaner according to claim 17, wherein the dust removal unit comprises a bar-type body and a dusting part extending from the body so that the dusting part contacts the drum brush at the first position and is separated from the drum brush at the second position.

19. The upright cleaner according to claim 18, further comprising an extension part extending from the body so that the extension part protrudes above the suction body and a bent part extending from an end of the extension part so that the bent part is bent toward a front of the suction body.

20. The upright cleaner according to claim 18, further comprising an extension part extending from the body so that the extension part protrudes forward from the suction body.

21. The upright cleaner according to claim 20, further comprising an actuating unit coupled to the suction body to cover the extension part, the actuating unit being configured to be moved between an actuating position at which the extension part is pressed and a releasing position at which the extension part is released.

22. The upright cleaner according to claim 21, further comprising a locking unit hingedly coupled to an upper part of the suction body, wherein the locking unit locks the actuating unit at the actuating position when the actuating unit is located at the actuating position.

23. An upright cleaner having a suction body, a main body and a handle, the upright cleaner comprising:

a case forming an external appearance of the suction body;

a drum brush rotatably provided in the case;

a dust removal unit movably provided in the case, the dust removal unit performing an actuating operation through which the dust removal unit contacts the drum brush to remove dust from the drum brush and a releasing operation through which the dust removal unit is separated from the drum brush;

a lever connected to the dust removal unit to control the dust removal unit to perform the actuating operation or the releasing operation;

an elastic part provided between the lever and a top of the case to elastically bias the lever upward; and
