Abstract

Disclosed is a vacuum cleaner including a sucking nozzle for sucking air; a dust collecting assembly including a dust collecting container with an opened top surface, a top lid for opening and closing a top of the dust collecting container, an inlet for sucking air to the inside of the dust collecting container, a filtering device coupled with the top lid, and an outlet provided at a bottom of the dust collecting assembly for discharging clean air to a lower part of the dust collecting container; and a cleaner body including a dust collecting assembly receiving recess for detachably receiving the dust collecting assembly, a polluted air outlet provided at the dust collecting assembly receiving recess and coupled with the dust collecting assembly inlet for discharging polluted air sucked in through the sucking nozzle, and a clean air inlet provided on a floor of the dust collecting assembly receiving recess and communicating with the outlet of the dust collecting assembly, and a clean air conduit for discharging the clean air to the outside of the vacuum cleaner.

Claims

1. A vacuum cleaner, comprising:

a sucking nozzle for sucking an air containing impurities by operation of a motor;

a dust collecting assembly including;

a dust collecting container having a dust collecting space for collecting impurities therein and having an opened top;

a top lid for opening and closing the top of the dust collecting container;

an inlet for sucking the air to the inside of the dust collecting container;

a filtering device provided in the dust collecting container for filtering impurities such as dust; and

an outlet provided at a bottom of the dust collecting assembly for discharging clean air separated from the impurities to a lower part thereof; and

a cleaner body including;

a dust collecting assembly receiving recess for detachably receiving the dust collecting assembly;

a polluted air outlet provided at the dust collecting assembly receiving recess, coupled with the dust collecting assembly inlet, and discharging the polluted air to the dust collecting assembly, the polluted air flowed in through the sucking nozzle;

a clean air inlet provided on a floor of the dust collecting assembly receiving recess and communicating with the outlet of the dust collecting assembly; and

a clean air conduit including a first end connected to the clean air inlet and a second end having a clean air outlet for discharging the clean air to the outside of the vacuum cleaner.

2. The vacuum cleaner of claim 1, wherein the top lid is detachably provided at the top of the dust collecting container.

3. The vacuum cleaner of claim 1, wherein the filtering device is detachably coupled to the top lid.

4. The vacuum cleaner of claim 2, wherein the top lid comprises a pass through hole perpendicularly bored such that the filtering device is inserted and withdrawn from the upper side of the top lid.

5. The vacuum cleaner of claim 4, wherein the filtering device is coupled on the top lid by means of a projector formed at a top end of the filtering device and a coupling lever provided on a top surface of the top lid for fixing the projector.

6. The vacuum cleaner of claim 1, wherein the filtering device comprises:

a filter formed in a cylindrical form having a perpendicular hollow; and

a filter supporter for supporting the filter.

7. The vacuum cleaner of claim 6, wherein the filtering device further comprises a supplementary filter provided inside of the filter and formed in a hollow.

8. The vacuum cleaner of claim 1, wherein the dust collecting assembly further comprises an inner flow tube having a bottom end coupled with the outlet of the dust collecting assembly and a top end extended upward toward the filtering device, for guiding the clean air separated from the dust collecting assembly to the outside of the dust collecting container.

9. The vacuum cleaner of claim 8, wherein the inner flow tube comprises a flow tube cover provided at the second end thereof so as to prevent the impurities from being flowed into the inside thereof.

10. The vacuum cleaner of claim 1, wherein the dust collecting assembly comprises a separation plate provided in the dust collecting container for preventing the impurities collected at a lower part of the dust collecting container from being risen by the air flow.

11. The vacuum cleaner of claim 10, wherein the separation plate is opened by rotation when the impurities collected in the dust collecting container are discharged.

12. The vacuum cleaner of claim 9, wherein the separation plate comprises two semicircular plates rotatably provided in an upper direction of the dust collecting container.

13. The vacuum cleaner of claim 10, wherein the separation plate is provided at a lower part of the filtering device.

14. The vacuum cleaner of claim 1, wherein the dust collecting container comprises:

a top container formed in a cylindrical form;

a bottom lid having a first end rotatably coupled with a first side of a lower end of the top container; and

a lid fixing device selectively fixing the bottom lid such that the bottom lid opens and closes the bottom of the top container.

15. The vacuum cleaner of claim 14, wherein the lid fixing device comprises a hook member having a hook at a first end thereof for catching the second end of the bottom lid;

and

a hook supporter provided at a second side of the top container for supporting the hook member.

16. The vacuum cleaner of claim 15, wherein the hook member is rotatably coupled with the hook supporter and having a second end coupled with an elastic material providing restoring force.

17. The vacuum cleaner of claim 15, wherein the bottom lid comprises a projector provided at a second end of the bottom lid and hooked by the hook of the hook member.

18. The vacuum cleaner of claim 1, wherein the dust collecting assembly inlet is provided at a predetermined location on a side of the dust collecting container in a tangential direction such that the polluted air sucked into the inner space of the dust collecting container is spiraled.

19. The vacuum cleaner of claim 18, wherein dust collecting assembly further comprises an anti rotation plate having a predetermined height and radially provided in the dust collecting container for preventing the impurities from being rotated by spiraled air.

20. A vacuum cleaner, comprising:

a sucking nozzle including a main sucking inlet with a width of 12 to 16 inches for sucking an air containing impurities from outside and an agitator for separating impurities form a floor;

a dust collecting assembly including;

a dust collecting container having a dust collecting space for collecting impurities therein and having an opened top;

a top lid for opening and closing the top of the dust collecting container;

an inlet for sucking in the air to the inside of the dust collecting container;

a filtering device provided in the dust collecting container for filtering impurities such as dust; and

an outlet provided at a bottom surface of the dust collecting assembly for discharging clean air separated from the impurities; and

a cleaner body including;

a dust collecting assembly receiving recess for detachably receiving the dust collecting assembly;

a polluted air outlet provided at the dust collecting assembly receiving recess, coupled with the dust collecting assembly inlet, and discharging the polluted air to the dust collecting assembly, the polluted air sucked in through the sucking nozzle;
