Description
WO 01/17688 PCT/KR00/00199 1 CYCLONE COLLECTOR FOR VACUUM CLEANER Technical Field The present invention relates to a cyclone collector, and more particularly, to a cyclone collector which is suitable for a vacuum cleaner.
Background Art Generally, a cyclone collector is a device collecting contaminants such as dusts, naps, and paper scraps contained in the air, using a cyclone principle. A cyclone collector is being used in various fields, and mainly applied to a vacuum cleaner for home use.
Various types of cyclone collectors are proposed in such documents as US Patent 4643748, US Patent 4353008, US Patent 5078761, US Patent 145499 and so on.
There may be two types of cyclone collectors: a forward directional cyclone collector in which a direction that air containing contaminants ("contaminated air") is induced and a direction that purified air is exhausted are substantially same; and a reverse-directional cyclone collector in which the said directions are different.
A related art uni-directional cyclone collector will be described in detail.
The related art uni-directional cyclone collector includes collectors in which air suction is performed in axial direction of a cyclone body (Figs. 1 and and other collectors in which air suction is performed in WO 01/17688 PCT/KR00/00199 2 tangent direction (Figs. 3 and 4).
An embodiment of the related art uni-directional cyclone collector will be described referring to Figs. 1 and 2.
A suction inlet 2 for sucking contaminated air in axial direction is formed at one side of a cylindrical cyclone body i, and an air vent 4 for exhausting purified air in axial direction is formed at other side thereof. A means 3 for supplying is formed inside the cyclone body 1 to rotate the air sucked in axial direction in tangent direction. A contaminant vent 5 is formed at the air vent 4 to guide contaminants separated by a centrifugal force in a tangent direction, and a collecting bag 6 is detachably mounted at one side of the contaminant vent As shown in Figs. 3 and 4, another embodiment of the related art uni-directional cyclone collector basically has a similar structure, except that there is no separate means for supplying rotative force since a suction inlet 12 is provided in tangent direction of a cyclone body 11.
Reference numerals 13, 14 and 15 denote an air vent, a contaminant vent, and a collecting bag, respectively.
Meanwhile, in case of applying the aforementioned cyclone collector to a vacuum cleaner, the cyclone collector may be mounted either in a vacuum cleaner body, or between the body and the suction inlet body.
The operation of the related art cyclone collector will be described referring to Figs. 1 and 2.
When a cyclone collector is in operation, a suction force generating means such as a suction fan (not shown) WO 01/17688 PCT/KR00/00199 3 is put to work to produce suction force, and contaminant is sucked into the cyclone body 1 together with air through the suction inlet 2.
At this time, contaminated air sucked in axial direction is given rotative force in tangent direction passing through the means 3 for supplying rotative force, and the contaminated air rotates in the cyclone body 1 as a result. Accordingly, relatively light air concentrates to the center of the cyclone body 1 and makes a whirlwind, because the relatively light air receives less centrifugal force. This air is exhausted through the air vent 4 when air flow in a direction of the air vent (exhaust air) is formed at a certain moment.
On the other hand, contaminants heavier than air receive more centrifugal force and flow along an inner wall of the cyclone body 1, so as to move into the collecting bag 6 mounted at the contaminant vent When more than certain amount of contaminants are collected in the collecting bag 6, a user may separate the collecting bag from the contaminant vent 5 and remove the contaminants, then may join the collecting bag to the contaminant vent 5 to use it again.
The operation principle of another embodiment of the related art cyclone collector (Figs. 3 and 4) is basically same with the aforementioned operation, except that contaminated air receives centrifugal force without any separate means for supplying rotative force, because the contaminated air is entered into the cyclone body in tangent direction.
WO 01/17688 PCT/KR00/00199 4 A related art reverse-directional cyclone collector will be described referring to Fig. A suction inlet 32 is formed at an upper part of a cylindrical cyclone body 31 to suck contaminated air in tangent direction, and a contaminant vent 34 for guiding the contaminants separated by the centrifugal force in tangent direction is formed at a lower part of the cyclone body 31. A collecting bag 35 is detachably mounted at the contaminant vent 34.
Meanwhile, unlike the forward directional cyclone collector, in the reverse-directional cyclone director, an air vent 34 for exhausting purified air is formed at which the suction inlet 32 is formed, that is, at the upper part of the cyclone body 31 in axial direction.
The operation of the aforementioned reverse-directional cyclone collector will be described below.
Contaminated air which is sucked into the suction inlet 32 rotates along an inner wall of the cyclone body 31 and at the same time descends. In this process, contaminants are separated from the cyclone body 31 and collected in the collecting bag 35. Meanwhile, purified air is moved up by the suction force applied through the air vent 33, changing its direction from the lower part of the cyclone body 1 to the air vent 33, to be exhausted outside of the cyclone body 31.
That is, in the reverse-directional cyclone collector, a flow (swirl) rotating along an inner wall of the cyclone body 1 becomes an exhaust air flow which 004354007 changes its direction at the lower part of the cyclone body (opposite to the air vent) and moves up. However, the related art cyclone collector has several problems.
First, since the contaminated air which is sucked into the cyclone body doesn't receive sufficient centrifugal force, contaminants are not effectively collected, but are exhausted outside of the cyclone body together with the exhaust air, thereby reducing the collecting efficiency.
Second, swirl flow and exhaust air flow generated in the cyclone body interfere with each other and generates flow resistance, thereby increasing pressure loss and noise. This problem is particularly serious in the reversedirectional cyclone collector. The reason why is that flow rotating at the lower part of the cyclone body comes into collision against exhaust air flow when the flow is changed to the exhaust air flow, thereby generating a warm air which acts as an air resistance element.
Disclosure of Invention Accordingly, the present invention is directed to a cyclone collector for vacuum cleaner that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
It would be desirable to provide a cyclone collector for vacuum cleaner, which improves collecting efficiency.
It would also be desirable to provide a cyclone collector for vacuum cleaner, which reduces flow resistance so as to reduce noise and pressure loss.
Additional features and advantages of the invention will be set forth in the .description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of 25 the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

Best mode for Carrying Out the Invention Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
An embodiment of the present invention will be explained referring to the accompanying drawings.
Fig. 6 is a longitudinal sectional view showing a cyclone collector in accordance with the first embodiment of the present invention. The first embodiment of a cyclone collector in accordance with the present invention will be described referring to Fig. 6.
Same elements as the related art cyclone collector are given same names and reference numerals, and explanations for those elements will be omitted.
The cyclone collector according to the first embodiment of the present invention basically includes a cyclone body 1, a contaminated air suction inLet 2, an air vent 4, a collecting bag 6, and a means 3 for supplying rotative force in the same manner as the related art cyclone collector.
However, in the cyclone collector of the present invention, a flow guide means is provided at a certain place inside the cyclone body. The flow guide means acts to improve a centrifugal force of air which is sucked into S. 2001.
9 the cyclone body i, and to reduce a flow resistance. At this time, the flow guide means is preferably located opposite to the air vent 4. In more detail, the flow guiding means is provided at an outlet of the rotative force supplying means 3.
The flow guide means includes a guiding member 7 and a flow interference prevention member 8 connected with the guide member 7, for guiding air to the inner wall of the cyclone body 1 and for reducing the flow resistance.
Preferably, the guide member 7 has a cylindrical shape.
The flow interference prevention member 8 increases in its shape from an air-suction part to an air-exhaust part, and the larger end is preferably subsided to form a depression 8a. This is because the flow interference prevention member 8 formed as above may guide air more efficiently to the inner wall of the cyclone body as the air moves from the air-suction part to the air-exhaust part. This is also because that the flow interference prevention member 8 may effectively prevent swirl and exhaust air flow from interfering with each other.
Any shape in which a size becomes larger from the air-suction part to the air-exhaust part can be applied for the flow interference prevention member 8. For example, a funnel shape, a trumpet shape, a semi-spherical shape, or a skirt shape may be applied for the flow interference prevention member 8.
The operation of a uni-directional cyclone collector in accordance with the first embodiment of the present 1 1 WO 01117688 PCT/KR00/00199 10 with the first embodiment of the present invention will be described referring to Fig. 6.
If the cyclone collector is set into operation, contaminated air is sucked into the cyclone body 1 through the suction inlet 2 of the cyclone body i. The sucked contaminated air is given a rotative force in tangent direction, passing through the rotative force supplying means 3.
The air to be exhausted, which is given a rotative force from the rotative force supplying means 3 is guided to an inner wall of the cyclone body 1. At this time, the contaminated air is spread to the inner wall of the cyclone body, more efficiently with the flow interference prevention member 8 of which the diameter becomes larger from the air-suction part to the air-exhaust part. That is, the contaminated air which is sucked into the cyclone body 1 is forcibly spreading to the inner wall of the cyclone body 1 by the flow guide means.
The air and contaminants efficiently guided to the inner wall of the cyclone body 1 by the flow guide means 8 receive different centrifugal forces because of weight difference.
Accordingly, the air which is relatively light concentrates to the center of the cyclone body 1 and generates a whirlwind, then is formed as an exhaust air flow at a certain moment and exhausted through the air vent 4. On the other hand, relatively heavier contaminants continually move along the inner wall of the cyclone body 1 and are then exhausted in tangent direction through the WO 01/17688 PCT/KRO/00199 11 contaminant vent 5, to be finally collected to the collecting bag 6.
In this process, an initial air flow (swirl) which is given a rotative force by the rotative force supplying means 3 is guided to the inner wall of the cyclone body 1 by the flow guide means. Accordingly, contaminants can efficiently be prevented from being directly exhausted to the air vent 4 together with the exhaust air without flowing to the inner wall of the cyclone body 1 by air exhaust pressure generated along the air vent 4.
A cyclone collector in accordance with the second embodiment of the present invention will be described referring to Fig. 7.
A basic structure of the second embodiment is similar to that of the first embodiment, that is, the second embodiment also includes a cyclone body 11, a contaminated air suction inlet 12, an air vent 13, and a collecting bag 15. However, the air suction inlet 12 is formed in tangent direction of the cyclone body 11, and thus a means for supplying rotative force is not formed.
A flow guide means is formed opposite to the air vent 14 also in the second embodiment, and the flow guide means includes a guide member 17 and a flow interference prevention member 18.
The operation principle of the second embodiment is same with that of the aforementioned first embodiment, and its description will be omitted.
A cyclone collector in accordance with the third embodiment of the present invention will be described WO 01/17688 PCT/KR00/00199 12 referring to Fig. 8.
In the third embodiment, a flow guide means which is a main feature of the present invention is applied to a reverse-directional cyclone collector. In the fourth embodiment, in the same manner as the aforementioned embodiments, a flow guide means includes a guide member 37 and a flow interference prevention member 38. The flow guide means is also provided opposite to the air vent 33, that is, at a lower part of the cyclone body 31. Of course, a larger end of the flow interference prevention member 38 is oriented to the air vent 33 and is depressed. In the fourth embodiment, the guide member 37 acts to guide contaminants separated by the centrifugal force to be efficiently exhausted to the collecting bag 35, rather than guide the suction air.
With the above structure, collision and interference may be efficiently decreased by the flow guide means in the process of changing swirl sucked by the contaminated air suction inlet 32 and rotating at the lower part of the cyclone body 31 to exhaust air flow, thereby reducing the flow resistance. Accordingly, pressure loss and noise may also be reduced.
In more detail, swirl rotating toward the lower part of the cyclone body 31 is given the air exhaust pressure through the air vent and changed to the exhaust air flow.
At this time, the flow may naturally be changed along the depression inside the flow guide means, thereby avoiding interference and collision between the air flows.
Furthermore, the flow guide means separates the WO 01/17688 PCTKR00/00199 13 contaminants flowing at the inlet of the contaminant vent inside the cyclone body 31 from the air which is changed from swirl flow to the exhaust air flow, so that the contaminants can be prevented from entering into the exhaust air by interference.
Meanwhile, the cyclone collector in accordance with the present invention may be mounted in either a main body of a vacuum cleaner, or between the main body and a suction inlet body of a vacuum cleaner, as described in the related art.
As aforementioned, the cyclone collector according to the present invention has the following advantages.
Since the contaminated air which is sucked into the cyclone body through the suction inlet is efficiently guided to the inner wall of the cyclone body in an initial step, the air receives sufficient centrifugal force.
Accordingly, the contaminants separated from the air move furthest to the center of the cyclone body, on which an air-exhaust pressure (vacuum pressure) acts, thereby efficiently preventing the contaminants from being externally exhausted together with the exhaust air.
Moreover, when swirl flow and exhaust air flow are formed within the cyclone body, a region of swirl flow and a region of exhaust air flow become distinctive by means of the flow guide means, thereby preventing mutual interference. Accordingly, pressure loss and noise can be reduced.
It will be apparent to those skilled in the art that various modifications and variations can be made in the WO01/17688 PCT/KROO/00199 14 cyclone collector for vacuum cleaner according to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention covers the modifications and variations of the invention provided they come within the scope of the appended claims and their equivalents.
