Definitions

  • the present invention relates generally to a vacuum cleaner and more particularly, to a suction port assembly of a vacuum cleaner for drawing in dirt on a surface being cleaned.
  • Vacuum cleaners draw in dirt on a surface being cleaned using a suction force generated by a vacuum source mounted in a main body thereof.
  • vacuum cleaners comprise a cleaner body having therein a motor that generates a vacuum force, a suction port assembly facing a surface being cleaned to draw in dirt on the surface, and an extension path for guiding the dirt drawn in into the suction port to the cleaner body.
  • the extension path often comprises an extension tube connector movably connected to the suction port assembly, an extension tube connected to the extension tube connector, and a suction hose between the cleaner body and the extension tube.
  • FIGS. 1A and 1B are perspective views schematically showing bottom and top sides, respectively, of a suction port assembly.
  • the suction port assembly comprises an upper housing 10 and a lower housing 11 .
  • a suction port 14 for drawing in dirt from a surface being cleaned, is formed in the lower housing 11 .
  • the lower housing 11 also has a dust moving channel 12 formed at opposite sides thereof, through which dusts positioned adjacent to the opposite sides S are drawn into a vacuum source through the suction port 14 .
  • the suction port assembly shown in FIGS. 1A and 1B is provided with a single suction path for transmitting the vacuum force by which dust can be drawn in.
  • the vacuum is most intense at the center C of the suction port 14 but decreases away from the center C. Therefore, cleaning efficiency is good at the center C of the suction port 14 but degrades towards the sides S of the suction port assembly. Accordingly, the suction port assembly is not efficient in cleaning large surface areas.
  • the top of the suction port assembly is usually made from an opaque material, it is impossible to determine if dirt is caught in the suction port assembly. It is therefore necessary to check the entire suction path of a vacuum cleaner in order to find the position at which the suction path is obstructed.
  • a suction port assembly that provides a more uniform vacuum and which allows for a see-through inspection of suction paths would be an improvement over the prior art.
  • An aspect of the present invention is to solve at least the above problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present invention is to provide an improved suction port assembly allowing efficient cleaning of a surface of large area and a vacuum cleaner having the same.
  • Another aspect of the present invention is to provide an improved suction port assembly allowing visual check of a path from the outside of the suction port assembly and a vacuum cleaner having the same.
  • a suction port assembly comprising upper and lower housings; a plurality of suction ports formed in the lower housing; and a plurality of paths formed in the upper and lower housings to guide air drawn in into the suction ports.
  • the upper housing defines first and second suction paths and a suction path cover defining a top of the first and second suction paths.
  • the upper housing is connected to the lower housing with a top cover.
  • a first joint part is formed along the edge of the path cover and a second joint part formed on the lower housing.
  • the upper and lower housings are tightly engaged with each other to minimize suction force losses caused by air leaks between the housings.
  • a fluid guide rib is formed on the first and second paths so as to guide the drawn-in air toward a vacuum source while preventing the swirling phenomena of the drawn-in air, whereby the loss of suction force can be further prevented.
  • the top cover is formed with a cutout section in a shape corresponding to that of the suction path cover, and the suction path cover is exposed to the outside through the cutout section.
  • the suction path cover is preferably made of a transparent plastic material, so that the first and second suction paths can be inspected for obstructions from the outside. Consequently, it is not needed to check the entire suction path of a vacuum cleaner when dirt might be caught in the suction port assembly.
  • FIGS. 1A and 1B are perspective views schematically showing the top and bottom sides of a conventional suction port assembly
  • FIG. 2 is a perspective view schematically showing a vacuum cleaner according to an embodiment of the present invention
  • FIG. 3 is an exploded perspective view of a suction port assembly according to an embodiment of the present invention.
