Definitions

  • the present invention relates to a dust separating apparatus employed for a vacuum cleaner. More particularly, the present invention relates to a multi cyclone dust separating apparatus, which utilizes centrifugation to separate dust from air flowed in the vacuum cleaner through multi steps.
  • vacuum cleaners include a suction brush that draws in dust from a surface to be cleaned, a dust separating apparatus that separates dust from air drawn in through the suction brush, and a suction motor that generates a suction force.
  • Conventional dust separating apparatuses which are mainly employed utilize a dust filter that requires inconvenient and frequent replacements and also creates an unsanitary condition.
  • Recently, cyclone dust separating apparatuses are being widely used. These apparatuses are beneficial in that they do not have a dust filter and, therefore, they can be used for long periods of time.
  • Cyclone dust separating apparatuses utilize centrifugation to separate and collect dust from the air.
  • cyclone dust separating apparatus Due to the structure and performance of cyclone dust separating apparatuses, they may fail to separate and collect dust particles of minute size. Recently, an enhanced cyclone dust separating apparatus has been developed that improves upon collecting and filtering minute dust particles in air through a two step methodology. Examples are multi cyclone dust separating apparatus applied by this applicant under the Patent No. 2003-62520 and cyclone dust separating apparatus published under No. US 2005/0050864 . This multi cyclone dust separating apparatus includes a plurality of second cyclones that are disposed on an outer circumference of a first cyclone. This results in a significant enhancement in collecting dust particles of minute size. However, the multi cyclone dust separating apparatus is still unable to completely remove minute dust. Accordingly, studies are currently underway on way to improve the efficiency of collecting minute dust particles.
  • an aspect of the present invention is to solve the above problems and/or disadvantages of the related art and to provide the advantages described below. Accordingly, an aspect of the present invention is to provide a multi cyclone dust separating apparatus that increases the rotary force of air drawn into second cyclones. This apparatus has improved designed structures based on the shape of the vacuum cleaner and the cyclone dust separating apparatus.
  • a multi cyclone dust separating apparatus includes a first and second cyclone unit, a cover unit, and a dust collecting unit.
  • the first cyclone unit comprises: a housing; a first cyclone chamber utilizing centrifugation to separate dust particles from air that is externally drawn in; a chamber outer wall forming the first cyclone chamber; a first inlet; and a first outlet.
  • the second cyclone unit comprises a plurality of cyclones arranged along an inner circumference of the housing so that minute dust particles may be separated by centrifugation from air that is drawn in from the first cyclone unit.
  • Respective cyclones include a second cyclone chamber, a second chamber outer wall, a second inlet, and a second outlet forming the second cyclone chamber.
  • the cover unit is mounted at the upper sides of the first and second cyclone units so that air discharged from the first cyclone unit is guided to the second cyclone unit and is discharged from the second cyclone unit into the outside.
  • the dust collecting unit collects dust separated from the air in the first and second cyclone units.
  • the second inlet of each cyclone of the second cyclone unit is lower than the first inlet of the first cyclone unit.
  • a part of at least one cyclone of the second cyclone unit is inserted into the dust collecting unit.
  • At least one cyclone of the second cyclone unit is completely inserted into the inside of the dust collecting unit.
  • the cover unit includes an air guide path allowing and rotarily inducing the air discharged from the first outlet of the first cyclone unit to each second inlet of the plurality of cyclones, a first cover having an outlet guide path to be fluidly communicated with the second outlets of the cyclones, a the second cover combined to cover the first cover and having a discharge pipe combining air exhausted from the plurality of out let guide paths and externally discharging the combined air.
  • the air guide path has horizontal parts radially disposed with reference to a center of the first cover, and vertical parts extending downwards by a predetermined length, such that one end is fluidly communicated to the horizontal parts and the other end is fluidly communicated to the second inlet of the respective cyclones.
  • the outlet guide path penetrates the inside of the vertical parts of the air guide path.
  • An air inducing member is formed inside the vertical parts, helping the air let in through the horizontal parts to descend, while maintaining rotary current, and lead into the second inlet of the cyclone.
  • the air inducing member is mounted on an outer circumference of the outlet guide path.
  • FIG. 1 is a separated perspective diagram of a multi cyclone dust separating apparatus according to one embodiment of the present invention
  • FIG. 2 is a sectional view in a viewpoint of II-II line of FIG. 1 ,
  • FIG. 3 is a separated perspective diagram of a multi cyclone dust separating apparatus according to another embodiment of the present invention.
  • FIG. 4 is a sectional view in a viewpoint of IV-IV of FIG. 3 .
  • a multi cyclone dust separating apparatus 100 that comprises a cyclone unit 110, a cover unit 400 combined to an upper side of the cyclone unit, and a dust collecting unit 500 that is combined to a lower side of the cyclone unit.
  • Cyclone unit 110 comprises a first cyclone unit 200 and a second cyclone unit 300, which has a plurality of cyclones 310.
  • First cyclone unit 200 comprises a housing 210 that forms a substantially cylinder-shaped appearance; a first chamber outer wall, mounted to the inside of housing 210, which forms a first cyclone chamber; suction pipe 260 which draws air into the inside of first cyclone chamber 220; and grill member 270 which connects to an upper part of first chamber outer wall 230.
  • First chamber outer wall 230 has a substantially cylindrical shape, similar to housing 210.
  • Space part 280 is formed between housing 210 and first chamber outer wall 230. Inserted into space part 280 are part of an air guide path 420, discharge guide path 430 of a cover unit, and part of second cyclone unit 300.
  • First chamber outer wall 230 has a lower side that is open and an upper part that opens through first outlet 250.
  • First inlet 240 is connected to suction part 260.
  • First outlet 250 is smaller than the inside diameter of first chamber outer wall 230.
  • Air inducing wall 231 is formed at an inner part of first chamber outer wall 230. Air inducing wall 231 is shaped in a spiral manner so that it gradually narrows for a predetermined distance toward the circumference from the outer side of first outlet 250. Accordingly, the air drawn in through first inlet 240 is guided by air inducing wall 231 and forms a rotary air current that is let into first cyclone chamber 220.
  • Suction pipe 260 guides dust entrained air into first cyclone chamber 220.
  • Suction pipe 260 penetrates housing 210 and is extended to first chamber outer wall 230.
  • Entry 261 is formed at the outer side of suction pipe 260 and is noncircular pipe shaped. Suction pipe 260 gradually guides air drawn in through entry 261 downwards.
  • Grill member 270 prevents relatively large dust particles, that have been separated by centrifugation in first chamber outer wall 230, from being counterflowed and let out through first outlet 250.
  • Grill member 270 has grill body 271 formed with a plurality of minute holes and a skirt combined to a lower side of the grill body.
  • Grill body 271 has a cylindrical shape and has an open upper side. The upper side of grill body 271 is connected to first outlet 250. The lower side of grill body 271 is closed and is connected to skirt 272. Skirt 272 prevents dusts centrifugally separated in first cyclone chamber 220 from being counterflowed.
  • Second cyclone unit 300 includes a plurality of cyclones 310 having the upper part inserted into the space part 280 and the lower side inserted into dust collecting unit 500 (Refer to FIG. 2 ).
  • the plurality of cyclones 310 are formed at an outer side of first chamber outer wall 230 in predetermined intervals. That is, cyclones 310 are formed around the outer circumference of first chamber outer wall 230, excerpt for the lower side of suction pipe 260.
  • Plurality of cyclones 310 includes second cyclone chamber 320, second chamber outer wall 330, second inlet 340, and second outlet 350.
  • Second chamber outer wall 330 is reverse cone shaped in such a manner that the diameter narrows as it goes downwards. A predetermined part of one end is severed. The upper and lower sides of second chamber outer wall 330 are open.
  • dust entrained air descends while forming a rotary air current. The dust in the air is centrifugally separated and flows out the lower side of second chamber outer wall 330.
  • second chamber outer wall 330 opens into second inlet 340. Air that is discharged from first cyclone chamber 220 is drawn into second chamber outer wall 330. The air is then discharged from second cyclone chamber 320 through second outlet 350 having been centrifugally separated.
  • Second inlet 340 of plurality of cyclones 310 is not the same as first inlet 240 of the first cyclone unit 200, in the height but lower. For the air to descend and form a rotary air current in first cyclone chamber 220, the air should be let in from the side of the upper part of first cyclone chamber 220. Accordingly, first inlet 240 of first cyclone chamber 220 is limitedly located. However, as illustrated, second inlet 340 of each of plurality of cyclones 310 is freely settable up to the height of first cyclone unit 200, regardless of the height of first inlet 240. According to an embodiment of the present invention, a part of the lower side of plurality of cyclones 310 is inserted into dust collecting unit 500.
  • second inlet 340 is freely controlled according to the shape of a vacuum cleaner (not shown) having the multi cyclone dust separating apparatus 100 such as to maximize usable space.
  • Vertical inducing part 423 mentioned later may be lengthened, thereby increasing a rotary force of the air and improving dust collection efficiencies.
  • Cover unit 400 comprises first cover 410 and second cover 440 formed at an upper part of first cover 410.
  • First cover 410 induces the air discharged from first cyclone unit 200 to respective plurality of cyclones 310 of the second cyclone unit.
  • First cover 410 has a plate shaped cover body 411, an air guide path 420, and a discharge guide path 430.
  • Mounted in a predetermined part of cover body 411 is a suction pipe route 412 corresponding to suction pipe 260 of first cyclone unit 200.
  • Air guide path 420 includes both a horizontal inducing part 421 radially disposed with reference to the center of cover body 411, and a vertical inducing part 422 extending downwards for a predetermined length so that air guide path 420 has one end fluidly communicating with horizontal inducing part 421 and the other end fluidly communicating with the second inlet of each of the plurality of cyclones 310. It is exemplified that vertical inducing part 422 is substantially the same as suction pipe 260 in height.
  • Horizontal inducing part 421 guides air that is discharged from first cyclone 200 and first outlet 250 into vertical inducing part 422, while forming a rotary air current. Accordingly, the air soaring toward the center of cover body 411 moves to all sides, guided by cover body 411.
  • Vertical inducing part 422 guides air that is drawn in through vertical inducing part 421 into each of the plurality of cyclones 310, thereby maintaining a rotary air current.
  • spiral air inducing member 423 is mounted inside vertical inducing part 422. Air inducing member 423 may be integrally formed with vertical inducing part 422. The air drawn in has an increased rotary force resulting in improved efficiencies of collection of minute dust particles.
  • the lower side of vertical inducing part 422 is fluidly communicated to second inlet 340 of each of the plurality of cyclones 310.
  • Discharge guide path 430 penetrates an inner part of vertical inducing part 422 of air guide path 420, and minute dust particles are centrifugally separated from second cyclone chamber 320 of the plurality of cyclones 310. The dust particles pass through discharge guide path 430 and are removed from the air. The cleaned air ascends again and flows out.
  • air inducing member 423 is formed at an inner side of vertical inducing part 422.
  • a spiral air inducing member may be formed at an outer side of discharge guide path 430.
  • Second cover 440 covers first cover 410.
  • Exhaust pipe 450 is formed at the upper part of second cover 440. Air that is discharged from each of the plurality of cyclones 310 is discharged through discharge path 430 and is exhausted out of multi cyclone dust separating apparatus 100.
  • Exhaust pipe 450 may or may not be formed at the upper side of second cover 440. Exhaust pipe 450 may also bemounted on the side of second cover 440.
  • First cover 410 and second cover 440 may be formed either integrally or separately.
  • Dust collecting unit 500 collects dust that is centrifugally separated from the air in the first and second cyclone unit 200, 300. Dust collecting unit 500 has the upper end open and the lower end closed. Dust collecting unit 500 is detachably formed at the lower side of cyclone unit 110 so that the collected dust may be easily removed.

  • the filtered air ascends through grill member 270 and flows out first outlet 250. Dust particles larger than the minute holes of grill member 270 fail to flow into grill member 270 and are filtered.
  • the air ascending through first outlet 250 collides with first cover 410 and spreads.
  • the air goes through horizontal inducing part 421 and vertical inducing part 422 and flows into second cyclone chamber 320 through second inlet 340.
