Cyclone dirt separating apparatus and vacuum cleaner having the same
First Claim
1. A cyclone dirt separating apparatus comprising:
- a cyclone body including a first cyclone chamber and a second cyclone chamber, the first cyclone chamber preliminarily separating dirt from air drawn in from an exterior by a centrifugal force, and the second cyclone chamber secondarily separating dirt from the air discharged from the first cyclone chamber;
an inflowing/outflowing cover provided at an upper end of the cyclone body, the inflowing/outflowing cover having inflow guide passages for guiding the air discharged from the first cyclone chamber to the second cyclone chamber and having outflow guide passages for discharging the air in the second cyclone chamber to an exterior;
a dirt collecting case coupled to a lower end of the cyclone body, the dirt collecting case collecting the dirt separated by the first and second cyclone chambers; and
a discharge guide duct passing through the cyclone body and the dirt collecting case, the discharging guide duct guiding the air discharged from the second cyclone chamber through the outflow guide passages toward a motor mounting space.

Abstract
A cyclone dirt separating apparatus and a vacuum cleaner having the same are disclosed. The cyclone dirt separating apparatus comprises a cyclone body including a first cyclone chamber in which dirt is separated preliminarily from air drawn in from an exterior by a centrifugal force; and a second cyclone chamber in which dirt is separated secondarily from the air discharged from the first cyclone chamber; and a dirt collecting case coupled to a lower end of the cyclone body for collecting the dirt. Also, the cyclone dirt separating apparatus further comprises a discharge guide duct passed through the cyclone body and the dirt collecting case and guiding the air discharged from the second cyclone chamber. Therefore, the air discharged through the discharge guide duct is directly entered to a motor mounting space of the vacuum cleaner.

9. A cyclone dirt separating apparatus comprising:
-
a cyclone body including a cyclone chamber in which dirt is separated from drawn-in air, an inlet port through which the drawn-in air enters the cyclone chamber, and an outlet port through which the drawn-in air is discharged from the cyclone chamber; an inflowing/outflowing cover provided at an upper end of the cyclone body, the inflowing/outflowing cover having inflow guide passages for guiding the air entering through inlet port to the cyclone chamber and having outflow guide passages for discharging the air in the cyclone chamber to an exterior; a dirt collecting case coupled to a lower end of the cyclone body for collecting the dirt separated from the drawn-in air; and a discharge guide duct passing through the cyclone body and the dirt collecting case in the substantially vertical direction, the discharging guide duct guiding the air discharged from the cyclone chamber through the outflow guide passages to a lower end of the dirt collecting case. - View Dependent Claims (10)

11. A vacuum cleaner comprising:
-
a cyclone mounting section; a main body including a motor mounting space installed at a lower end of the cyclone mounting section; and a suction nozzle coupled with the main body and a cyclone dirt separating apparatus mounted attachably/detachably to the cyclone mounting section, wherein the cyclone dirt separating apparatus comprises a cyclone body including a first cyclone chamber and a plurality of second cyclone chambers, the first cyclone chamber preliminarily separating dirt from air drawn in through the suction nozzle by a centrifugal force, the plurality of second cyclone chambers being disposed at a periphery of the first cyclone chamber for centrifugally separating dirt from the air discharged from the first cyclone chamber; a dirt collecting case coupled to a lower end of the cyclone body for collecting the dirt separated from the air; and a discharge guide duct being passed through the cyclone body and the dirt collecting case, the discharging guide duct guiding the air discharged from the plurality of second cyclone chambers such that the air directly enters the motor mounting space. - View Dependent Claims (12, 13)
