Description
- This application claims the benefit of Korean Patent Application No. 2004-50991 filed Jul. 1, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
- The present invention relates to a vacuum cleaner, and more particularly, to a suction port assembly of a vacuum cleaner through which contaminants of a surface being cleaned are drawn into the cleaner body.
- Generally, a vacuum cleaner sucks in dust particles and contaminants of a surface being cleaned with a suction force generated by a vacuum source mounted inside the cleaner body. Vacuum sources usable in vacuum cleaners are well known to those of ordinary skill in the art and a description of them is omitted for brevity.
- The vacuum cleaner usually includes a cleaner body which houses a motor therein to generate suction force, a suction port assembly facing a surface being cleaned to draw in contaminants therefrom, and a fluid passage extended from the suction port assembly to guide drawn contaminants to the cleaner body. The extended fluid passage includes an extension pipe connector movably connected with the suction port assembly, an extension pipe connected with the extension pipe connector, and a suction hose connected with the extension pipe.

FIG. 1 is a bottom perspective view of a prior art conventional suction port assembly 2. - Referring to
FIG. 1 , the suction port assembly includes anupper housing 10 and alower housing 11. Asuction port 14 is formed in thelower housing 11 to draw in contaminants from the surface being cleaned. Thelower housing 11 is also provided withcontaminant channels 12 at both laterally opposite sides S thereof, and therefore, contaminants can also be drawn into the vacuum source from both sides S of the suction port assembly 2 through thesuction port 14. - The suction port assembly 2, however, generally has only one fluid passage to transfer the vacuum force for sucking in the contaminants. Accordingly, while suction force at the center C of the
suction port 14 is strong, both sides S have relatively degraded suction force. In other words, cleaning efficiency is good at the center C of thesuction port 14, but cleaning efficiency degrades at the sides S of thesuction port 14. The cleaning efficiency is particularly low when cleaning a wide area. - An effort has been made to overcome this problem in the conventional art, and there has been a suggestion to form suction port at both sides of the suction port assembly. However, a suction port at both sides of the suction port assembly is accompanied with the problem of cleaning efficiency degradation at the center of the suction port assembly.
- The present invention has been developed in order to solve the above drawbacks and other problems associated with the conventional arrangement. An aspect of the present invention is to provide an improved type of suction port assembly which can provide higher cleaning efficiency not only at the sides, but also at the center area, and a vacuum cleaner having the improved suction port assembly.
- The above aspects and/or other features of the present invention can be substantially achieved by providing a suction port assembly, including, upper and a lower housings, a first and a second suction port formed on the lower housing, at least one upper opening pierced in the upper housing, allowing an external air to be drawn there through by the suction force of the first and the second suction ports, and at least one lower opening formed on the lower housing, the lower opening located between the first and the second suction ports and fluidly communicating with the upper opening such that the air drawn through the upper opening is guided to between the first and the second suction ports to scatter the dusts therefrom. Cleaning efficiency at the center of the suction port assembly increases. The vacuum cleaner efficiency also increases not only at both sides, but also at the center of the suction port assembly, can be provided.
- According to one aspect of the present invention, the suction port assembly has an upper and a lower housing, and first and second suction ports formed in the lower housing. Additionally, the lower housing is provided with a first and a second dust channels connected with the first and the second suction ports, and lower openings at the first and the second dust channels, respectively. There are also upper openings formed in the upper housing, in fluid communication with the lower openings.
- By the structure as described above, external air is drawn through the upper openings by the suction force at the suction ports, and drawn air is passed through the lower openings, scattering the dusts from the center part of the suction port assembly. The scattered dusts are moved through the first and the second dust channels, and drawn through the first and the second suction ports. As a result, cleaning efficiency of the suction port assembly increases not only at both sides, but also at the center.
- When the dusts are drawn through the suction ports, the dusts are guided through the first and the second fluid passages formed in the upper and lower housings, and therefore, moved to the cleaner body. The fluid passage cover, forming the top of the first and the second fluid passages, may preferably be formed of a transparent material so that the user can observe the movement of the drawn air from outside, and therefore, relieved from the inconvenience of having to check the entire fluid passages of the vacuum cleaner when problem occurs in the fluid passages of the suction port assembly.
- The above aspects and features of the present invention will be more apparent by describing certain embodiments of the present invention with reference to the accompanying drawings, in which:
-
FIG. 1 is a bottom perspective view of a prior art conventional suction port assembly for a vacuum cleaner; -
FIG. 2 is an exploded perspective view of a suction port assembly according to an embodiment of the present invention; -

FIG. 4 is a perspective view of a vacuum cleaner according to an embodiment of the present invention; and -
FIG. 5 is a front perspective view of a suction port assembly to explain operation thereof according to an embodiment of the present invention. - Certain embodiments of the present invention will be described in greater detail with reference to the accompanying drawings.
- In the following description, same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description such as a detailed construction and elements are nothing but the ones provided to assist in a comprehensive understanding of the invention. Thus, it is apparent that the present invention can be carried out without those defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.
- Referring to
FIGS. 2 and 3 , asuction port assembly 200 according to an embodiment of the present invention comprises anupper housing 211 forming an upper part of thesuction port assembly 200, and alower housing 222 forming the lower part.

Thedust channel 240 is divided by arib 246 formed on the bottom of thelower housing 222 between afirst dust channel 242 operatively connected with thefirst suction port 226 and asecond dust channel 244 operatively connected with thesecond suction port 228. Twolower openings 235 are formed in thefirst dust channel 242 and thesecond dust channel 244 in near to therib 246, respectively. Alternate embodiments of theopenings 235 include oval or triangular openings as well. Thelower openings 235 may be formed in a variety of locations and configurations so long as they are operatively coupled to the first and thesecond suction ports - By the structure as described above, external air can flow through the
upper openings 213 and be guided toward the bottom of thelower housing 222 through thelower openings 235. As the external air is drawn in, dust between the first and thesecond suction ports second suction ports second dust channels suction port assembly 200 can be efficiently cleaned and cleaning efficiency at the center part C also increases. As a result, the vacuum cleaner can effectively clean even the wide cleaning area. The dotted arrows ofFIG. 3 indicate a passage through which the air from theupper openings 213 is flowed through the first and thesecond suction ports lower openings 235. Two pairs ofspaced wheels 239 are mounted front and rear sides of the bottom of thelower housing 222. - As shown in

Accordingly, dusts scattered by the air from the upper andlower openings second suction ports fluid passages FIG. 4 ). Thelower housing 222 is provided at its rear end with a lower extensionpipe connector mount 224 on which the lower side of an articulatingcoupler 118 of theextension pipe connector 116 is rotatably mounted. Thelower housing 222 is additionally provided with a fluidpassage cover mount 234 to which thefluid passage cover 250 is mounted. - The
fluid passage cover 250 takes on substantially the arch configuration in vertical section with respect to the motion of drawn in air. Thefluid passage cover 250 is preferably formed of transparent plastic material for the observance of the user. Accordingly, the user may timely notice problems such as dust blockage in the fluid passage. Aflange 258 is extended along the boundary of thefluid passage cover 250, which is pressed by theupper cover 212 during the engagement of theupper cover 212 with thelower housing 222. - The assembling process of the
suction port assembly 200 according to one embodiment of the present invention will be described below. - First, the articulating
coupler 118 of theextension pipe connector 116 is inserted in the lower extensionpipe connector mount 224 at the rear end or backside of thelower housing 222. Thefluid passage cover 250 is mounted on the fluid passage cover mount part formed on thelower housing 222. Next, with the mounting of thefluid passage cover 250 to thelower housing 222, the articulatingcoupler 118 of theextension pipe connector 116 is movably mounted on the upper and lower extensionpipe connector mount upper cover 212 is then attached to the lower housing 122 and thefluid passage cover 250. The suction port assembly is finally assembled by thefastening members 236 such as screws, engaged through corresponding fastening holes 238 formed on theupper cover 212 and thelower housing 212. Also, theupper cover 212 presses on theflange 258 of thefluid passage cover 250 such that thefluid passage cover 250 and thelower housing 222 can be airtight-engaged with each other. -
