Description

Cyclone collector for vacuum cleaner {Cyclone collector for vacuum cleaner}

The present invention relates to a cyclone dust collector for a vacuum cleaner, and more particularly, in a vacuum cleaner having a dust collector adopting a cyclone dust collecting method, a vacuum configured to more efficiently empty foreign matter collected in the case of the dust collector. It relates to a cyclone dust collector for a cleaner.

1 shows a configuration of a general vacuum cleaner, and as shown, an extension pipe 4 mounted at an end of a suction nozzle 2 for sucking air containing foreign substances, and a suction nozzle connected to the extension pipe. It is composed of a handle (6), which is assembled at the other end and includes an operation button, a connection hose (8) for connecting the handle to the main body, and a vacuum cleaner main body (1).

Inside the main body 1 of the vacuum cleaner, a motor (not shown) for generating a suction force for sucking external air, and a filter device 3 for filtering foreign matter contained in the air to be sucked are built-in. have.

The general vacuum cleaner configured as described above is a filter device (3) in which external air sucked through the suction nozzle (2) is fastened to the inside of the main body (1) via an extension pipe (4) and a connection hose (8). After filtering, clean air is configured to be exhausted through an exhaust port provided on one side of the vacuum cleaner main body.

Here, the filter device 3 mounted inside the main body of the vacuum cleaner is, for example, mainly made of a paper bag, but recently, a cyclone dust collector adopting a cyclone dust collecting method is also used.

However, the mounting of the filter device only inside the main body of the vacuum cleaner may increase the volume of the main body of the vacuum cleaner due to the installation of the filter device having a large volume to collect a predetermined amount. In addition, the filter device is not replaced until the inside of the filter device is filled with a foreign material, which may cause decay of the foreign material and propagation of bacteria, which may cause hygiene problems. In order to solve this problem, recently, a vacuum cleaner equipped with a cyclone dust collector which filters most of foreign matters on one side of the extension pipe 4 has been released.

As shown in FIG. 1, the vacuum cleaner is equipped with a cyclone dust collector 10 on one side of the extension tube 4. That is, the dust collector 10 is installed in the vicinity of the handle 6 at the upper part of the extension pipe 4 to which the handle 6 is fastened to the upper end, and is configured to primarily filter relatively large foreign substances. . The dust collector 10 collects foreign matter in the air by a cyclone method.

And Figure 2 shows a perspective view for showing the configuration of the dust collector 10 by a conventional cyclone method. As shown, the inlet (11a) is formed on the upper side so that the air containing the foreign material is introduced into the inside, and the dust collecting case (11) to form the spiral air flow; A cover 12 which opens and closes the dust collecting case and allows filtered air to pass therethrough; A filter part 13 fastened to the bottom of the cover; And a separating plate 14 installed in close contact with the lower inner circumferential surface of the dust collecting case 11 to separate the inside of the dust collecting case 11 into an upper dust collecting space 15 and a lower dust collecting space 15 '; The separating plate 14 is formed in a flat plate shape, characterized in that the inlet hole (14a) for guiding the foreign matter passes through the dust collecting space on one side. In addition, by forming a stop rib 11b in the longitudinal direction on the inner wall of the lower dust collecting space 15 'of the dust collecting case 11 to support the bottom of the separating plate 14, the separating plate is lowered to the lower side of the dust collecting case. The lower dust collecting space 15 ′ is prevented from narrowing.

The air containing the foreign matter sucked through the suction nozzle 2 shown in FIG. 1 is sucked into the dust collector 10 configured as described above. At this time, the air containing the foreign matter is introduced into the inlet port (11a) formed on the upper sidewall of the dust collector 10 to form a spiral flow inside the dust collector (10). When the spiral flow is formed in this way, the foreign material having a relatively large weight moves to the lower dust collecting space 15 ′ of the dust collector 10 through the inlet hole 14a by gravity and is collected at the lower end portion. The foreign matter collected in the lower dust collecting space 15 ′ is difficult to move to the upper dust collecting space 15 in which the filter unit 13 is located by the separating plate 14. On the other hand, the relatively light foreign matter flows through the upper dust collecting space 15 and is filtered by the filter unit 13, the air separated from the foreign matter by the filter unit 13 is handled through the upper end of the extension pipe (4) (6) flows into the connecting hose (8) and flows into the main body (1) of the vacuum cleaner.

Thus, after the heavy foreign matter is collected in the lower dust collecting space by the separating plate 14 firstly, when the light foreign matter filtered by the filter unit 13 is introduced into the inside of the main body 1, Fine dust is finally filtered out by the filter device 3 installed in the filter device 3. As a result, the clean air exiting the filter device 3 is exhausted to the outside of the main body. That is, clean air is discharged from the main body to the outside after the primary and secondary filtering by the cyclone dust collecting method and the tertiary filtering by the filter device 3 including the paper filter are performed.

Through this process, when foreign matter is gradually collected in the interior of the dust collector 10, the flow of air is not made smoothly by the dust collected. Thus, the user should separate the dust collector 10, the foreign matter is collected and clean empty. First, the dust collecting device 10 is separated from the extension pipe 4 and the cover 12 is removed from the dust collecting case 11. Then, the separation plate 14 installed inside the dust collecting case 11 is removed, and the dust collecting case 11 is turned upside down to pour out the foreign matter collected. In addition, the foreign matter on the surface of the filter portion 13 fastened to the cover 12 is removed by brushing off or washing with water. In this way, the dust collector 10 in a clean state can be assembled and fastened to one side of the extension pipe 4 again.

However, according to the cyclone dust collector of the conventional vacuum cleaner as described above, the following disadvantages are pointed out.

In the conventional vacuum cleaner, the cyclone dust collector 10, when the foreign matter is collected to the extent that obstructs the flow of air, to separate the separation plate 14 installed in the dust collecting case 11, the lower dust collecting space Foreign matter collected at 15 'can be easily removed. For this reason, there is a hassle to separate the separating plate 14 which is installed in close contact with the inner circumferential surface of the dust collecting case 11 formed in a flat plate shape.

In addition, the hands are dirty due to foreign matter and dust on the separator 14, which is unsanitary. At this time, a disadvantage arises in that the separation plate 14 is pulled out by using another tool to be separated out of the dust collecting case 11.

In consideration of the problems described above, it can be seen that it is most preferable to configure the separation plate so that there is no hassle to separate the separation plate in order to easily remove and clean foreign substances and dust collected in the cyclone dust collector.

An object of the present invention, when the foreign matter or dust collected in the lower dust collecting space is tilted or upside down when the dust collecting case, the cyclone of the vacuum cleaner that can remove the foreign matter more easily by being guided by the separator plate to fall easily to the outside To provide a dust collector.

Cyclone dust collector for a vacuum cleaner according to the present invention for achieving the above object, the inlet is formed in which the air containing the foreign matter is introduced into one side of the upper, the dust is collected to form a spiral flow Casing; A separating plate dividing the dust collecting casing into an upper dust collecting space and a lower dust collecting space; And a cover for opening and closing the dust collecting casing and allowing the filtered air to pass therethrough. In particular, the separator is provided with an opening in the center, and is formed so as to form a diameter slope of the lower surface relative to the opening, characterized in that the inlet hole for guiding the foreign matter to the lower dust collecting space is formed on one side. .

And according to another embodiment of the present invention, the inlet is formed in the inlet through which the air containing the foreign matter is introduced into the inside of the upper portion, the inlet air to form a spiral flow; A cover for opening and closing the dust collecting casing and allowing filtered air to pass therethrough; And a separating plate dividing the dust collecting casing into an upper dust collecting space and a lower dust collecting space; The separator is provided with an opening in the center, and is formed to form a gentle inclined surface of which the lower surface is downward based on the opening, characterized in that the inlet hole for guiding foreign matter into the lower dust collecting space is formed on one side.

And according to one embodiment, it further comprises a filter unit provided on the lower side of the cover. Moreover, it is more preferable that such a filter part is detachably installed in a cover. And the bottom part of the said filter part is comprised so that spaced apart above the opening part of a separation plate.

In addition, the separating plate may be integrally molded on the inner wall of the dust collecting casing.

Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

Figure 3 shows a partially cut state to show the internal configuration of the dust collecting casing having a cyclone dust collecting function according to the present invention, the dust collecting device having such a dust collecting casing 21 will be attached to the upper end of the extension tube of the vacuum cleaner . The dust collecting casing 21 of the dust collecting apparatus according to the present invention is configured such that the first dust collecting by the cyclone method and the second dust collecting by the filter unit can be sequentially performed.

First, the cyclone type first dust collection will be described. As shown, air, including foreign matter and dust, will be introduced into the dust collecting casing 21 through the inlet 21a connected to the upper end of the extension pipe, and the air introduced into the dust collecting casing will be collected. A spiral flow is formed along the inner surface of the casing 21. The air flowing into the upper dust collecting space 25 of the dust collecting casing 21 forms a spiral flow when the air flowing into the dust collecting casing 21 is introduced from the upper side of the dust collecting casing 21. This is because the inlet port 21a is configured to flow in the tangential direction of the inner surface. That is, it can be seen that the inlet 21a extends in the horizontal direction from the upper sidewall of the dust collecting casing 21 and is formed to be inclined upwardly, so that the flow of air can form a spiral flow.

In addition, a relatively large foreign matter among the foreign matters contained in the air of the spiral flow formed in the upper dust collecting space 25 of the dust collecting casing 21 is sag downwards in the dust collecting casing 21 by a cyclone method. That is, the relatively heavy foreign matter is lowered down by its own weight and collected in the lower dust collecting space 25 ′ through the inlet hole 24a of the separator 24.

On the other hand, it will be described with respect to the cyclone-type secondary dust collection made in the upper dust collecting space (25). The separated air is separated from the foreign matter in the lower dust collecting space 25 ′ and the air introduced into the upper dust collecting space 25 through the opening 24c includes relatively light foreign matter floating in the upper dust collecting space 25. Flow with the air. The air moves to the outside of the dust collecting casing 21 by the suction force transmitted from the main body through the exhaust hole 22a of the cover 22. At this time, the cover 22 is configured to have a filtering function to filter foreign matter. By the filtering function of the cover 22 is to filter the foreign matter in the air exiting the inside of the dust collecting casing (21). In the filtering by the cover 22, the cover 22 itself can filter the air instead of forming the filter unit 23 or the filter unit 23 fastened to the bottom of the cover 22 to be detachably attached. Of course, it can be configured to include a filter member.

Next, the flow of air in relation to the filter unit 23 will be described. The air primarily filtered by the spiral flow formed inside the dust collecting casing 21 rises upward from the central portion of the dust collecting casing 21. The rising air is substantially caused by primary dust collection. Contains relatively fine dust that does not separate.

This air is made by the secondary dust collection in the process of flowing from the outer surface of the filter unit 23, the air is exhausted through the exhaust hole 22a of the cover 22 while passing through the filter unit 23 It is substantially introduced into the vacuum cleaner body. That is, the main body of the vacuum cleaner is connected to the dust collecting casing through the suction hose, and the air in which the foreign matter is filtered through the suction hose is introduced into the main body of the vacuum cleaner.

The air, which has been subjected to secondary dust while passing through the filter unit 23, is finally separated from all foreign matters by a filter device installed inside the vacuum cleaner main body, and then passes through the motor housing to cool the motor. It will be exhausted to the outside. This process is made possible by the suction force generated by the motor installed inside the vacuum cleaner.

As described above, the filter unit 23, after the relatively large foreign matter is collected by the cyclone dust collection method inside the dust collecting casing 21, for filtering fine foreign matter such as dust contained in the air will be. Therefore, according to the present invention, after the foreign matter is first collected in the cyclone method inside the dust collecting casing 21, the fine dust and the like is configured to be collected by the filter unit 23 secondly, and the dust is collected. It can be seen that it is configured to perform a process of separating the fine dust by the air discharged from the inside of the casing (21).

The filter unit 23 used in the present invention may use any kind of filter as long as it can filter fine dust. For example, it is also possible to use a filter made of a paper material, and it is also preferable to shape | mold using polyester which can make a fiber material. When using a filter made of polyester material that can form a general fiber material, the convenience of washing can be expected by repeated use.

In addition, the filter portion 23 is most preferably molded to have a cylindrical shape in which the pleats in the longitudinal direction are repeatedly formed in the circumferential direction in order to maximize the dust collection efficiency by increasing the surface area in contact with the air flowing therethrough. . By forming such a pleat, the contact area with air passing through the filter part 23 will be widened enough, and it will be possible to raise dust collection efficiency more. In the present embodiment, although the pleated in the longitudinal direction is illustrated a filter portion repeatedly molded in the circumferential direction, it is obvious that this can not be limited by this embodiment. For example, in order to sufficiently expand the contact area with the air for filtering the dust, it is also possible to form the bellows-like wrinkles.

On the inner wall of the dust collecting casing 21 according to the embodiment of the present invention, the separating plate 24 forms a triangular cross section 24b. That is, the separating plate 24 has a lower surface 24d forming a diameter slope downward with respect to the opening portion 24c, an upper surface 24u forming a plane, and a foreign substance into the lower dust collecting space 25 'on one side. It can be seen that the air is composed of the inlet hole (24a) is introduced.

In the separation plate 24 formed as described above, foreign matter contained in the air flowing while forming a spiral flow along the inner wall surface of the upper dust collecting space 25 is lower in the dust collecting casing 21 by a cyclone method. Go down to the lower dust collecting space (25 ') through the inlet hole (24a). Air separated from heavy foreign matter in the lower dust collecting space 25 ′ is introduced into the upper dust collecting space 25 through the opening 24c. At this time, the lower surface (24d) of the separation plate 24 forms a diameter slope to guide the air so that most of the rising air flows into the upper dust collecting space 25 through the opening (24c). As a result, the air flowing back through the inlet hole 24a in the lower dust collecting space 25 'becomes weak, and the flow of air containing foreign matter flowing into the lower dust collecting space 25' from the upper dust collecting space 25 '. Will not affect. As a result, the primary dust collecting process is less disturbed by the air in which the foreign material having a relatively large mass is separated, thereby effectively collecting dust.

4 is a perspective view showing a state in which the dust collecting casing 31 according to another embodiment of the present invention is cut, and a separator plate 34 formed on the inner wall of the dust collecting casing 31 is formed at the center portion thereof. It is shape | molded so that the lower surface 34d may form the gentle inclined surface downward with respect to the opening part 34c which exists.

By the separating plate 34, a lower dust collecting space 35 ′ is formed at an inner lower end of the dust collecting casing 31, and the lower dust collecting space 35 ′ is a spiral formed inside the dust collecting casing 31. It is relatively less affected by Ryu. Forming the separator 34 as described above allows the foreign matter collected by the cyclone method to be separated and stored in the lower dust collecting space 35 ', and the foreign matter collected in the lower dust collecting space 35' continues. It is to prevent the rotation.

The separation plate 34 which separates the foreign matter sagging downward in the dust collecting casing 31 according to another embodiment as shown in FIG. 4 to collect in the lower dust collecting space 35 ′, is the dust collecting casing 31. It has a circular shape in plan view so that it can be inserted into the inside, and the shape of the longitudinal cross section 34d is shaped so that the upper surface 34u is flat and the lower surface 34d is curved.

Of course, according to another embodiment of the present invention, it is also possible to form a semi-circular shape in which the longitudinal cross-section (34d) of the separating plate 34 is curved in both the upper surface and the lower surface.

In addition, it can be seen that a circular opening 34c is formed in the central portion of the separator 34. The opening 34c is formed in the central portion of the separating plate 34 in this way so that the foreign matter collected in the lower dust collecting space 35 'can be easily poured out of the dust collecting casing 31. That is, when a lot of foreign matter collects in the lower dust collecting space 35 ', the foreign matter in the inside of the dust collecting casing 31 is separated, and then the dust collecting casing 31 is lifted upside down. The foreign matter gathered in the space 35 'is poured through the opening 34c. At this time, since the separating plate 34 is in a state in which the central portion is opened and the lower surface 34d forms a gentle inclined surface, foreign matters poured out in an inverted state form the separating plate (in which the inclined surface is formed). It will be guided by the bottom face 34d of 34 and will be able to be completely discharged very easily.

On the circumferential outer side surfaces of the separating plates 24 and 34, foreign matters falling inside the dust collecting casings 21 and 31 are introduced into the lower dust collecting spaces 25 'and 35' at the lower end portions 24a, 34a) is molded. The foreign matter falling downward due to the spiral flow of the air flowing in the dust collecting casings 21 and 31 is guided by the inflow holes 24a and 34a of the separating plates 24 and 34 to collect dust. To 25 'and 35'.

The separating plates 24 and 34 having the functions as described above may be molded integrally with the inner walls of the dust collecting casings 21 and 31 to eliminate the trouble of assembling the separating plates 24 and 34. In addition, when the foreign substances collected in the lower dust collecting space 25 'and 35' are emptied by forming the lower surfaces 24d and 34d into diameter slopes or gentle inclined surfaces, the foreign substances are warped through the openings 24c and 34c. It is guided along the lower surface of the photo to easily exit the lower dust collection space.

The present invention as described above, it can be seen that it is a basic technical idea that the second filtering in the separator and the dust collecting casing can easily empty the foreign matter collected in the lower dust collecting space. And within the scope of the basic technical idea of the present invention, of course, other modifications are possible to those of ordinary skill in the art.

For example, in the description of the embodiment of the present invention, the above-described dust collecting casing describes the present invention through an embodiment provided at an upper end portion provided with a handle in an extension tube. However, it is apparent that the dust collecting casing according to the present invention cannot be limited by this embodiment. For example, the dust collecting casing according to the present invention can be applied to the dust collecting casing mounted on the main body of the vacuum cleaner. That is, it is also possible to install the dust collecting casing of the structure mentioned above in the main body of a vacuum cleaner, and to filter the air containing the foreign material which flows in through an extension pipe in the main body.

According to the present invention as described above, foreign matter can be efficiently collected in the lower dust collecting space partitioned below by a separator plate in the dust collecting casing, it is further configured to easily empty the foreign matter collected in the lower dust collecting space. It can be seen. Therefore, according to the present invention, foreign matter moving downward by the separator plate is smoothly guided and collected in the lower dust collecting space, and when emptying the collected foreign matter, it forms the lower surface of the separator plate even when the separator is not separated from the dust collecting casing. Under the guidance of the inclined surface, foreign matter can be easily removed from the lower dust collection space.
