Definitions

  • the present invention relates to a cyclone dust collecting apparatus, and more particularly, to a multi-cyclone dust collecting apparatus having a plurality of cyclones in symmetrical arrangement, which provides improved suction speed and dust collecting efficiency.
  • a vacuum cleaner generally draws in dust-containing air and separates dust from the drawn air.
  • Such a conventional vacuum cleaner generally uses a dust filter as a dust collecting means, which needs replacement when ridden with dusts. Accordingly, users feel inconvenient and unhygienic as they replace the contaminant dust-laden filter with hands.
  • a cyclone dust collecting apparatus which is reusable almost permanently, has been suggested.
  • the cyclone dust collecting apparatus separates dust from the air using centrifugal force, and users can re-use the apparatus after removing the collecting dusts.
  • the cyclone dust collecting apparatus is reusable and has removed a need for use of dust bag or dust filter, it also has a shortcoming in that it is inefficient to collect fine dusts.
  • the same applicant has noted this problem, and thus provided a multi-cyclone dust collecting apparatus with improved fine dust collecting efficiency in Korean Patent Application Nos. 2003-62520 , 2003-63211 , 2003-63212 and 2003-63213 .
  • the suggested cyclone dust collecting apparatuses provide higher fine dust collecting efficiency than the prior ones, however, since it requires formation of a plurality of cyclone currents, there is a problem that flow speed at a suction brush decreases. Accordingly, an improvement is required.
  • the present invention has been made to overcome the problems of the prior art, and accordingly, it is an object of the present invention to provide a multi-cyclone dust collecting apparatus which is capable of collecting fine dusts from a drawn air and improving flow speed at a suction brush.
  • a multi-cyclone dust collecting apparatus including at least two multi-cyclone units comprising a first cyclone for collecting large particles of dust, and a second cyclones for collecting fine particles of dust.
  • the multi-cyclone units may include the second cyclones formed around an outer circumference of the first cyclone substantially in a letter 'C' formation.
  • a multi-cyclone dust collecting apparatus may include a first and a second cyclone units comprising a first cyclone for collecting large particles of dust, and a second cyclones for collecting fine particles of dust, an air inlet through which dust-laden air is separated and flowed into the first and the second multi-cyclone units, respectively, and an air outlet through which air from the second cyclone of the first and the second multi-cyclone units is gathered and externally discharged.
  • the air inlet may include a partitioning plate, and a first and a second air inlet ducts which are divided by the partitioning plate.
  • the first and the second multi-cyclone units may be arranged in symmetrical relation with each other.
  • the first and the second multi-cyclone units may respectively comprise dust receptacles, which are separately formed from each other.
  • FIG. 1 is a sectional view of a multi-cyclone dust collecting apparatus according to an embodiment of the present invention.
  • FIG. 2 is a sectional view taken on line II-II of FIG. 1.
  • a multi-cyclone dust collecting apparatus has a plurality of cyclone units of mirror image structure in symmetrical arrangement.
  • a multi-cyclone dust collecting apparatus includes a first multi-cyclone unit 100, a second multi-cyclone unit 200, an air inlet 300 and an air outlet 400.
  • the first multi-cyclone unit 100 includes a first cyclone 110 and a second cyclone 120.
  • the first cyclone 110 is eccentrically connected with the air inlet 300, and there are a plurality of second cyclones 120 around the first cyclone 110 in letter 'C' formation.
  • the second multi-cyclone unit 200 has a mirror image structure as that of the first multi-cyclone unit 100, and mounted in a symmetrical relation with the first multi-cyclone unit 100 with respect to the air inlet 300.
  • the second multi-cyclone unit 200 has a second dust receptacle 230 which is separately formed from the first dust receptacle 130. Additionally, a second discharge air pipe 240 is provided.
  • the ambient air including dust is drawn into a cleaning unit such as a suction brush of the vacuum cleaner and supplied into both the first and the second multi-cyclone units 100 and 200 through the air inlet 300.
  • a partitioning plate 301 is provided in the air inlet 300 to separate interior space into a first air inlet duct 310 and a second air inlet duct 320. Accordingly, dust-laden air is supplied into the first multi-cyclone unit 100 through the first air inlet duct 310 and is supplied into the second multi-cyclone unit 200 through the second air inlet duct 320. Because the air is branched after it is drawn into a single inlet, a larger amount of air can be drawn from the suction brush (not shown) and also, a larger amount of large particles of dusts can be collected.
  • the air outlet 400 is formed in a cover C that is engaged to the top of the first and the second multi-cyclone units 100 and 200. Due to the presence of the air outlet 400, air from the first and the second discharge air pipes 140 and 240 of the second cyclones 120 can be gathered into one space and discharged toward a vacuum suction motor (not shown) provided at the cleaner body.
  • Air including dust is drawn through the air inlet 300 and branched into the first and the second multi-cyclone units 100 and 200 through the first and the second air suction ducts 310 and 320, which are separated by the partitioning plate 301. Accordingly, dust is separated from the air in the first and the second multi-cyclone units 100 and 200, respectively. More specifically, large particles of dust are firstly separated in the first cyclone 110 of the first multi-cyclone unit 100, and then fine particles of dust are secondly separated by centrifugal force at the plurality of second cyclones 120. The same operation may occur in the second multi-cyclone unit 200, which is formed in symmetry with the first multi-cyclone unit 100.
  • air is branched off once it is drawn into a single gate and dust is separated from the drawn air simultaneously in the plurality of multi-cyclone dust collecting apparatuses.
  • reduction of flow speed in the dust-laden air from the suction brush (not shown) can be prevented.
