Cyclone dust-collecting device and vacuum cleaner having the same
First Claim
1. A vacuum cleaner comprising:
- a cleaner body having a suction port assembly to draw in dirt-laden air from a cleaning surface and a suction pipe fluidly communicating with the suction port assembly; and
a cyclone dust-collecting device having a cyclone chamber to centrifugally separate the air drawn in through the suction pipe, and an air discharge port to discharge an cleaned air which is separated from the dirt in the cyclone chamber.

Abstract
A vacuum cleaner includes a suction port assembly, a motor generating a suction force at the suction port assembly, and a cyclone dust collecting device for centrifugally separating air drawn in through the suction port assembly and the motor in sequence. The cyclone dust-collecting device includes an air discharge port penetratingly formed on an outer circumference of the cyclone dust-collecting device and exposed to an outside of the cleaner body, for guiding the air discharged to the outside. Accordingly, since the air discharge port is disposed in the cyclone dust collecting device, not in the cleaner body, a discharge channel for connecting the cyclone dust collecting device and cleaner body is omitted and thus a structure of the vacuum cleaner becomes simplified.

17. A cyclone dust-collecting device comprising:
-
a cyclone head disposed in a cleaner body to connect with a suction pipe, air drawn in from a cleaning surface through a dirt suction port of the cleaner body flowing into the cyclone head through the suction pipe;
a dirt receptacle removably connected with the cyclone head and thereby forming a cyclone chamber to centrifugally separate the air drawn in through the suction pipe;
an air discharge port penetratingly formed through an outer circumference of the cyclone head exposed to the outside of the cleaner body to discharge the air discharged from the cyclone chamber to the outside; and
a discharge cover pivoting between a first position to open the air discharge port and a second position to close the air discharge port, wherein the discharge cover is pivoted to the first position by the air discharged from the air discharge port when the motor is driven.

18. A vacuum cleaner comprising:
-
a cleaner body having a suction port assembly and a suction pipe;
a cyclone head disposed in the cleaner body to connect with the suction pipe a dirt receptacle connected with the cyclone head to centrifugally separate the air drawn in through the suction pipe;
a motor disposed in the cleaner body to be located in an air passage between the cyclone chamber and the suction port assembly, for generating a suction force at the suction port assembly during a driving operation and forcedly conveying the air drawn in through the suction port assembly to the cyclone chamber;
an air discharge port penetratingly formed through an outer circumference of the cyclone head exposed to the outside of the cleaner body, for discharging a cleaned air which is centrifugally separated from dirt in the cyclone chamber to the outside; and
a discharge cover disposed at the cyclone head to open and close the air discharge port, wherein the discharge cover is pivoted to open the air discharge port by the air discharged when the motor is driven, and is pivoted to close the air discharge port by a self-weight when the motor is not driven.
