Abstract

A cyclone dust collecting apparatus has: a cyclone body; a suction pipe extended to be protruded into the cyclone body by penetrating one side of the cyclone body in order to guide an air, which has been drawn into through a suction unit, into the cyclone body; a discharge pipe for guiding a clean air centrifugally separated in the cyclone body to an outside of the cyclone body; and a guide member for guiding the air, which whirls along a side wall of the cyclone body after being drawn into through the suction pipe, to a lower side of the suction pipe. According to the cyclone dust collecting apparatus of the present invention, a deterioration of suction force of the cyclone dust collecting apparatus is prevented, and thus a dust collection efficiency of the cyclone dust collecting apparatus will be improved.

Claims

1. A cyclone dust collecting apparatus comprising:

a cyclone body;

a suction pipe connected with one side of the cyclone body in order to guide air, which has been drawn into the cyclone body through a suction unit; and

a discharge pipe for discharging clean air having been centrifugally separated from entrained dust in the cyclone body, to outside of the cyclone body,

wherein the suction pipe extends into the cyclone body so as to protrude into the cyclone body, and the drawn air is guided in a direction tangential to the cyclone body by a front end protruding into the cyclone body.

2. The cyclone dust collecting apparatus of claim 1, wherein the cyclone body further comprises:

a cylindrical side wall connected with the suction pipe;

an upper wall connected for covering an upper end of the side wall; and

a guide member for guiding the air, which whirls along an inner circumference of the cyclone body after being drawn into through the suction pipe, to underneath the suction pipe.

3. The cyclone dust collecting apparatus of claim 2, wherein the guide member further comprises:

a sloping side for connecting the lower side of the suction pipe with the upper wall adjacent to an upper part of the suction pipe, and

the sloping side is sloped downwardly in the direction of flow of the drawn air.

4. The cyclone dust collecting apparatus of claim 2, wherein

the upper wall is removably attached to the upper part of the side wall, and

the guide member protrudes from a lower side of the upper wall.

5. A cyclone dust collecting apparatus, comprising:

a cylindrical-type cyclone body having an upper opening;

an upper wall removably connected with an upper end of the cyclone body, the upper wall for opening and closing the upper opening of the cyclone body;

a suction pipe connected with one side of the cyclone body in order to guide an air, which has been drawn into through a suction unit, into the cyclone body; and

a discharge pipe for discharging clean air to outside of the cyclone body after dust has been centrifugally separated in the cyclone body,

wherein the suction pipe extends into the cyclone body and protrudes into the cyclone body, and the drawn air is guided in a direction tangential to the cyclone body by a front end protruded into the cyclone body.

6. The cyclone dust collecting apparatus of claim 5, wherein a guide member protrudes from the lower side of the upper wall in order to guide the air, which whirls along the inner circumference of the cyclone body after being drawn into the suction pipe, to a side underneath of the suction pipe.

7. The cyclone dust collecting apparatus of claim 6, wherein the guide member further comprises:

a sloping side for connecting the lower side of the suction pipe with the upper wall of the cyclone body placed at an upper part of the suction pipe, and

the sloping side slopes downwardly in the direction of flow of the drawn air.

8. The cyclone dust collecting apparatus of claim 7, wherein

the guide member further comprises a groove, corresponding to a type of the suction pipe, formed at one side and connected to the suction pipe when connecting the upper wall to the cyclone body, and

one side of the suction pipe is inserted into the groove to connect the upper wall to the cyclone body.
