Description
- This application claims the benefit of Korean Patent Application No. 2005-93114 filed on Oct. 4, 2005 with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference
- The present invention relates to a suction brush for a vacuum cleaner, and more particularly to a suction brush having improved manipulation capability.
- In general, a conventional suction brush for a vacuum cleaner has a suction port formed in the bottom thereof, to suction dust or dirt from a surface to be cleaned, and one or more dust guide grooves for guiding dust to the suction port. As seen in
FIG. 1 , the suction brush via a suction motor (not shown) absorbs dust together with ambient air throughopposite ends dust guide groove 5 when the bottom surface of the body 1 of the suction brush is in close contact with carpet. The dust and air introduced into thedust guide groove 5 is suctioned into the vacuum cleaner through thesuction port 7. Then, the dust is collected in a dust collection section (not shown), and the air is filtered and discharged to the outside of the vacuum cleaner. - The performance of a conventional suction brush is generally based on dust removal capability (suction force) and manipulation capability (push force) for smoothly moving the suction brush on a carpet. If the suction brush is in close contact with the carpet, the dust removal capability is enhanced. However, if the suction brush is in close contact with the carpet, the manipulation capability for moving the suction brush is considerably deteriorated. Therefore, the suction force and the push force are contrary to each other. Accordingly, there is a need for designing a suction brush so that both the suction force and push force are simultaneously optimized.
- When cleaning a carpet using a conventional suction brush, as shown in
FIG. 1 , theopposite ends dust guide groove 5 and thesuction port 7 are in close contact with the carpet due to the suction force. As a result, when a user moves the suction brush 1 in any direction on the carpet the suction force serves as a resistance force against the movement of the suction brush 1. - In order to overcome the above-mentioned problem, a pair of
wheels body 2 of the suction brush 1, as shown inFIG. 1 . However, when cleaning a bristly area, a carpet or bedding, thedust guide groove 5 and thesuction port 7 are still in close contact with the surface being cleaned, thereby still having the same inconvenience to the user. - In order to solve the above-mentioned inconvenience, Korean Patent Registration Nos. 244348 and 133742 disclose a suction brush having an air suction structure which allows ambient air to be introduced between the bottom surface of the suction brush and a surface to be cleaned through a part of the bottom surface of the suction brush so as to weaken the vacuum pressure generated between the bottom surface of the suction brush and the surface being cleaned.
- With this suction brush, it is the manipulation capability of the suction brush may be improved by weakening the vacuum pressure, but only if the surface being cleaned is a hard floor. If the surface being cleaned is bristly or soft like a carpet or bedding, the surface being cleaned is in contact with the suction brush by the air suction structure. Accordingly, the manipulation capability is deteriorated as the contacting force between the surface being cleaned and the suction brush is increased.
- Korean Patent Publication No. 2000-7490 discloses a suction brush, which is exclusively used for bedding. When suction force is generated, a suction brush rapidly absorbs ambient air through plural air suction openings formed on the top of the suction brush and blows the air out to the surface being cleaned, that is, the surface of the bedding, thereby facilitating the removal of various foreign matters. With this suction brush, however, because the air suction openings are exposed to the outside, noise is generated around the air suction openings as the ambient air is rapidly suctioned into the air suction openings. Because the suction brush and the surface being cleaned (the surface of bedding) are still in close contact with each other, the manipulation capability of the suction brush is not improved.
- Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a suction brush of a vacuum cleaner, which is improved in manipulation capability when the suction brush is in contact with a surface to be cleaned.
- Another object of the present invention is to provide a suction brush of a vacuum cleaner which can reduce a noise.
- In order to achieve the above-mentioned objects, there is provided a suction brush for a vacuum cleaner comprising a body, the bottom side of which is formed with a suction port; a cover for covering the top side of the body; and an air jetting path for absorbing ambient air from the bottom side of the body and jetting the air toward a surface to space the bottom side from the surface to be cleaned.
- The body may comprise a bottom panel having a dust guide groove formed in the bottom surface thereof so as to guide dust-laden air from the front and lateral sides of the body to the suction port, and a top panel interposed between the bottom panel and the cover, wherein it is preferable that the top and bottom panels are spaced from each other at the rear side thereof, thereby forming an air suction gap for introducing air from the lower side of the suction, and that the bottom panel may have a plural jetting holes formed along the portions of the the dust guide groove.
- Because the air jetting path may comprise an air suction gap, a space formed between the top and bottom panels, and plural jetting holes for discharging the air to the surface to be cleaned, it is possible to improve the manipulation capability of the suction brush as the distance between the dust guide groove and the surface to be cleaned is increased by the air jetted from the air jetting path.
- In addition, because the air suction gap is located at a position higher than that of the bottom side of the bottom panel, ambient air can be smoothly introduced into the air suction gap. Furthermore, because the air to be jetted through the jetting holes is absorbed from the bottom side of the body, which is not exposed to the outside, it is possible to minimize the noise generated when absorbing the air.
- The above aspects and features of the present invention will be more apparent from the description for certain embodiments of the present invention taken with reference to the accompanying drawings, in which:
-
FIG. 1 is a perspective view of a conventional suction brush of a vacuum cleaner; -
FIG. 2 is a partially cut-away perspective view illustrating an internal construction of a suction brush of a vacuum cleaner according to an embodiment of the present invention; -

FIG. 5A is a graph comparing an embodiment of the present invention and a conventional suction brush, in terms of suction force which indicates dust removal capability; and -
FIG. 5B is a graph comparing the embodiment of the present invention and the conventional suction brush in terms of push force. - Hereinbelow, certain embodiments of the present invention are described in detail with reference to accompanying drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
-
FIG. 2 is a partially cut-away perspective view illustrating an internal construction of a suction brush of a vacuum cleaner according to an embodiment of the present invention,FIG. 3 is a bottom view of the suction brush ofFIG. 2 , andFIG. 4A is a cross-sectional view taken along line X-X ofFIG. 2 , andFIG. 4B is a enlarged view of Y illustrated inFIG. 4A . - As shown in
FIG. 2 , thesuction brush 10 of a vacuum cleaner according to an embodiment of the present invention has abody 15 which comprises abottom panel 14 which contacts the surface to be cleaned, atop panel 13 located on the top of thebottom panel 14. - As shown in
FIG. 3 , thebottom panel 14 is formed with adust guide groove 17 on the bottom side thereof for absorbing dust-laden air from a surface to be cleaned through the oppositelateral portions 17 a, and asuction port 19 is formed through thebottom panel 14 at the center of thedust guide groove 17. - The
top panel 13 is wider than thebottom panel 14 in the direction of advancing the vacuum cleaner, so that the rear portions of the top andbottom panels FIG. 1 ) is formed between the rear portions of the top andbottom panels air suction gap 21 is an inflow opening, from which an air jetting path is originated. In addition, thebottom panel 14 has a plurality of jetting holes 23 (FIG. 2 ) formed and arranged along left and right portions of therear edge 17 b of thedust guide groove 17. - There is no limitation to the shape and diameter of the
jetting holes 23, the space betweenadjacent jetting holes 23, or the arranged distance of thejetting holes 23, as long as air is jetted to the surface to be cleaned through theplural jetting holes 23, so that a certain gap can be produced between the surface to be cleaned and thebottom panel 14 through the jetting pressure. In order to increase the jetting velocity of air, it is preferrable to arrange a plurality of small-sized holes as thejetting holes 23. - An air jetting path B (
FIGS. 4A and 4B ) for absorbing and jetting air to the surface to be cleaned originates from theair suction gap 21, which is an ambient air inflow opening, and consists of aspace 22 formed between the top andbottom panels air suction gap 21 toward thejetting holes 23, allowing thejetting holes 23 to discharge the air that passed through thespace 22. That is, the air flows through the air jetting path B which originates from theair suction gap 21, and connects to thespace 22 and the jetting holes 23. - The operation of the suction brush of a vacuum cleaner with the above-mentioned construction is now described with reference to
FIGS. 4A and 4B . - Initially, the vacuum cleaner is powered on to operate a vacuum motor, and vacuum pressure is transferred to the
suction brush 10. Then, a user applies thesuction brush 10 in close contact with a surface to be cleaned, e.g., a carpet. Between the carpet and the bottom side of thesuction brush 10, a predetermined level of vacuum pressure is produced. - Consequently, dust scattered on the carpet and air is absorbed into the
suction brush 10 along the air suction path A. That is, dust-laden air is drawn in by suction into theopposite side portions 17 a of thedust guide groove 17, guided to the center of thedust guide groove 17, then introduced into thesuction port 19. Next, the dust, that has passed through thesuction port 19, travels toward the rear side of thesuction brush 10 through the space between thecover 11 and thetop panel 13. In the rear part of the bottom side of thesuction brush 10, ambient air is introduced into thebody 15 through the air jetting path B and then jetted to the carpet. That is, as shown inFIGS. 4A and 4B , the air introduced through theair suction gap 21 passes thespace 22 between the top andbottom panels dust guide groove 17 and moved along the air suction path A. The remaining air is jetted to the surface to be cleaned. - At this time, the
suction brush 10 is somewhat floated by the air jetted through the jetting holes 10 and therefore, thereby spacing thesuction brush 10 and the carpet from each other, to form a gap between them. As a result, the contacting force between thesuction brush 10 and the carpet is reduced and accordingly, the user can easily pull or push thesuction brush 10 during the cleaning. In addition, because the air being introduced through the air jetting path B is introduced and discharged through the bottom side of the body, the noise generated at the air jetting path B is insignificant to the user. -
FIG. 5A is a graph comparing an embodiment of the present invention and a conventional suction brush in terms of suction force which indicates dust removal capability, andFIG. 5B is a graph comparing the embodiment pf the present invention and the conventional suction brush in terms of push force. Referring toFIG. 5A , even if plural suction openings are formed, there is no substantial change in suction efficiency. However, referring toFIG. 5B , it can be confirmed that the force required for a user to move the suction brush (push force) is substantially reduced. - Noise is generated around the
air suction gap 21 as the air is absorbed. However, according to the embodiment of the present invention, it is possible to reduce the noise as compared to the prior art, because thesuction brush 10 absorbs the air through theair suction gap 21, which is formed in the bottom side of thesuction brush 10. Thus, because air is not suctioned through exposed portions, such as the top or lateral sides of the suction brush, the noise is significantly reduced. - As described above, according to the present invention, there is an advantage in that it is possible to improve the manipulation capability of
suction brush 10 by forming agap 21 between thedust guide groove 17 and a surface to be cleaned using the air jetted from the air jetting path B so that the contacting force between thesuction brush 10 and the surface to be cleaned is reduced. In addition, because the air to be jetted through the jetting holes 23 is absorbed from the bottom side of the body of the suction brush, which is not exposed to the outside, it is possible to reduce the noise generated when the air is absorbed. - Although representative embodiments of the present invention have been shown and described in order to exemplify the principle of the present invention, the present invention is not limited to the specific embodiments. It will be understood that various modifications and changes can be made by one skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, it shall be considered that such modifications, changes and equivalents thereof are all included within the scope of the present invention.
