Abstract

Disclosed is a dust collecting apparatus is provided that includes a dust canister body, a part of which becomes an exposed side exposed outside a cleaner body. The cleaner body has a first dust separating chamber for separating large-sized dirt and second dust separating chamber for collecting fine dust; a cyclone body having a cyclone chamber which separates the fine dust from the air passing through the first dust separating chamber; and an outlet pipe protruding from lower surfaces of the first and second cyclone bodies to upper sides of the first and second cyclone chambers, wherein at least a part of the exposed side of the dust canister body is made of a transparent material so as to simultaneously see through the first and second dust separating chambers, and at least a part of the cyclone body is made of the transparent material to see through the cyclone body.

Claims

1. A dust collecting apparatus which is detachably coupling with a vacuum cleaner, comprising:

a dust canister body, a part of which becomes an exposed side exposed outside a cleaner body upon mounting in the cleaner body, and which comprises a first dust separating chamber for separating large-sized dirt from air flowed in through an inlet port formed at one side thereof by using inertia and gravity, and second dust separating chamber, which is isolated from the first dust separating chamber, for collecting fine dust from the air passing through the first dust separating chamber;

a cyclone body having a cyclone chamber which is in fluid communication with the first dust separating chamber and separates the fine dust from the air passing through the first dust separating chamber by using centrifugal force generated when the air is rotated; and

an outlet pipe which is protruded from lower surfaces of the first and second cyclone bodies to upper sides of the first and second cyclone chambers,

wherein at least a part of the exposed side of the dust canister body is made of a transparent material so as to simultaneously see through the first and second dust separating chambers, and at least a part of the cyclone body is made of the transparent material to see through the cyclone body.

2. The apparatus according to claim 1, wherein the cyclone body is eccentrically arranged within the second dust separating chamber so as to form a protruded portion protruded from the exposed side of the dust canister body, and at least the protruded portion is made of the transparent material so as to see through the cyclone body.

3. The apparatus according to claim 1, wherein the cyclone body is eccentrically arranged within the second dust separating chamber so as to form a common portion contacted with a portion of the exposed side of the dust canister body, and at least the common portion is made of the transparent material to see through the first and second cyclone chambers.

4. The apparatus according to claim 1, wherein the first and second dust separating chambers are isolated from each other by a partition wall, and at least a part of the partition wall is made of the transparent material.

5. The apparatus according to claim 1, wherein the first dust separating chamber is provided with an inertia blocking plate which is arranged at a position corresponding to the inlet port of the dust canister body so that the dirt flowed through the inlet port in the first dust separating chamber collides with the inertia blocking plate.

6. The apparatus according to claim 5, wherein the inertia blocking plate protrudes from an inner circumference of the first dust separating chamber and then bends in a gravity direction.

7. The apparatus according to claim 5, wherein the inertia blocking plate is protrudes to an outside of the first dust separating chamber, and the inlet port is formed at a side of the inertia blocking plate.

8. The apparatus according to claim 1, wherein the cyclone chamber further comprises a spiral guide for increasing rotational force of the air flowing in the cyclone chamber, and the spiral guide is tinted with a brighter color than the cyclone body in order to clearly see the dirt flowing in the cyclone body.

9. The apparatus according to claim 1, further comprising a cover detachably coupled with an upper side of the dust canister body so as to close and open an inside of the dust canister body, and wherein a dust exhaust port, through which the dust can be moved, is formed between an upper side of the cyclone body and a lower side of the cover, and thus the air containing the dust is flowed from a side of the cyclone body and rotated and risen in the cyclone chamber and then exhausted through the dust exhaust port to the second dust separating chamber.
