- Referring to
FIGS. 1 and 2 , avacuum cleaner 1 having a cyclone contaminant collectingapparatus 40 according to an exemplary embodiment of the present disclosure includes asuction nozzle 10, anextension pipe assembly 20, and acleaner body 30. - The
suction nozzle 10 moves along a surface to be cleaned and draws in contaminants. A contaminant suction port (not illustrated), in through which air and contaminants are drawn, is formed at a bottom surface of thesuction nozzle 10. A body-mountingportion 11 onto which thecleaner body 30 is mounted is formed at a top surface of thesuction nozzle 10. Also, a pair ofwheels 12 to allow thesuction nozzle 10 to smoothly move on the surface to be cleaned is disposed at opposite sides of thesuction nozzle 10. When thevacuum cleaner 1 is used as an upright type, as illustrated inFIG. 1 , thecleaner body 30 is coupled to the body-mountingportion 11 of thesuction nozzle 10. - The
extension pipe assembly 20 connects thesuction nozzle 10 with thecleaner body 30, and includes anextension pipe 21 and aflexible hose 22. Agrip 23 is formed at a connecting portion between theextension pipe 21 and theflexible hose 22. Therefore, a user grabs thegrip 23 to move thesuction nozzle 10. When thevacuum cleaner 1 is used as the upright type as illustrated inFIG. 1 , theextension pipe assembly 20 is fixed to a rear surface of thecleaner body 30, that is, asecond sidewall 32. - The
cleaner body 30 supports a vacuum generator (not illustrated) to generate a suction force to draw in contaminants and the cyclonecontaminant collecting apparatus 40 to separate and collect drawn-in contaminants. Thecleaner body 30 has afirst sidewall 31 that becomes a bottom surface when thecleaner body 30 is stood up in a longitudinal direction thereof as illustrated inFIG. 1 and thesecond sidewall 32 that becomes a bottom surface when thecleaner body 30 is laid down in the longitudinal direction thereof as illustrated inFIG. 2 . Thefirst sidewall 31 becomes the bottom surface that contacts the body-mounting portion 11 of thesuction nozzle 10 when thevacuum cleaner 1 is used as the upright type as illustrated inFIG. 1 . Thesecond sidewall 32 is formed perpendicularly with respect to thefirst sidewall 31, and theextension pipe assembly 20 is fixed to thesecond sidewall 32. Thesecond sidewall 32 becomes the bottom surface when thevacuum cleaner 1 is used as a canister type as illustrated inFIG. 2 . Thecleaner body 30 is partitioned into afirst portion 33 in which the vacuum generator is disposed and asecond portion 34 in which the cyclonecontaminant collecting apparatus 40 is disposed by apartition wall 35. The vacuum generator is disposed between thepartition wall 35 and thefirst sidewall 31. The cyclonecontaminant collecting apparatus 40 is disposed above thepartition wall 35. Thesecond portion 34 in which the cyclonecontaminant collecting apparatus 40 is disposed has an opened front surface. - The vacuum generator is in fluid communication with the cyclone
contaminant collecting apparatus 40 via a discharging duct 36 (seeFIG. 3 ) disposed at an inner surface of thesecond sidewall 32 of thecleaner body 30. - Referring to
FIGS. 1 and 3 , the cyclonecontaminant collecting apparatus 40 includes acyclone unit 50 to separate contaminants from the drawn-in air and acontaminant receptacle 70 to collect separated contaminants. - The
cyclone unit 50 is disposed so that a longitudinal center axis CL is parallel to thefirst sidewall 31 of thecleaner body 30. Therefore, when thevacuum cleaner 1 is used as the upright type as illustrated inFIGS. 1 and 3 , the longitudinal center axis CL of thecyclone unit 50 becomes substantially horizontal with respect to the surface to be cleaned 3. Thecyclone unit 50 includes acyclone body 51 to form a space in which the drawn-in air and contaminants whirl, an air-enteringpipe 52 to allow the contaminants and air to enter an inner side of thecyclone body 51, and an air-dischargingpipe 53 through which air having contaminants removed is discharged. - The
cyclone body 51 is formed substantially in a hollow cylindrical shape, and the longitudinal center axis CL thereof is parallel to thefirst sidewall 31 of thecleaner body 30. A contaminant-dischargingopening 57 through which the separated contaminants are discharged is formed at an upper portion of a side surface of thecyclone body 51, that is, at a position farthest away from thesecond sidewall 32 of thecleaner body 30. In this exemplary embodiment, the contaminant-dischargingopening 57 is formed substantially in a rectangular shape. The contaminant-dischargingopening 57 may have a size so that the contaminants separated in thecyclone body 51 can be smoothly discharged through the contaminant-dischargingopening 57 by a centrifugal force, and the contaminants collected in thecontaminant receptacle 70 can be prevented from flowing backward into thecyclone body 51 through the contaminant-dischargingopening 57. Atop cover 55 may be detachably disposed at the top end of thecyclone body 51. Aguide pipe 55 a may be formed to extend from an inner surface of thetop cover 55 toward the air-dischargingpipe 53. A contaminant-dischargingpipe 58 may be formed to extend outside from the side surface of thecyclone body 51 in the contaminant-dischargingopening 57. The contaminant-dischargingpipe 58 may have a shape corresponding to the shape of the contaminant-dischargingopening 57 and a larger section area than that of the contaminant-dischargingopening 57. In this exemplary embodiment, the contaminant-dischargingpipe 58 is formed in a rectangular pipe having a rectangular section larger than that of the contaminant-dischargingopening 57. - The air-discharging
pipe 53 is formed substantially at a center of a bottom surface of thecyclone body 51, and the bottom surface thereof is disposed on thesecond sidewall 32 of thecleaner body 30. The air-dischargingpipe 53 is formed substantially in a hollow cylindrical shape with opposite opened ends, and is in fluid communication with the dischargingduct 36 disposed at thesecond sidewall 32 of thecleaner body 30. Therefore, air discharged from the air-dischargingpipe 53 moves to the vacuum generator via the dischargingduct 36. Also, as illustrated inFIG. 3 , afilter portion 54 having a plurality ofslits 54 a may be disposed at a top end of the air-dischargingpipe 53. Thefilter portion 54 disposed at the top end of the air-dischargingpipe 53 can filter contaminants moving with discharging air. - The air-entering
pipe 52 is disposed at a lower portion of the side surface of thecyclone body 51, that is, a position near thesecond sidewall 32 of thecleaner body 30. Air entering the air-enteringpipe 52 whirls inside thecyclone body 51 around the longitudinal center axis CL of thecyclone body 51. The air-enteringpipe 52 is in fluid communication with theextension pipe assembly 20. - A supporting
wall 60 to support thecyclone body 51, as illustrated inFIG. 3 , may be disposed below thecyclone body 51. A leadingend 58 a of the contaminant-dischargingpipe 58 is formed to project from the supportingwall 60 as illustrated inFIG. 7 . A sealingprojection 61 may be disposed around the leadingend 58 a of the contaminant-dischargingpipe 58 on a bottom surface of the supportingwall 60. A connectinggroove 62 in which a connectingprotrusion 76 formed at atop wall 72 of thecontaminant receptacle 70 is inserted may be formed at an outer circumference of the supportingwall 60. - The
contaminant receptacle 70 is disposed at a side of thecyclone unit 50, that is, below thecyclone unit 50 as illustrated inFIG. 3 , and is formed to be detachable with respect to thecleaner body 30. Therefore, thecontaminant receptacle 70 can be mounted or separated parallel with respect to thefirst sidewall 31 of thecleaner body 30 and perpendicular with respect to thesecond sidewall 32 of thecleaner body 30. When thevacuum cleaner 1 is used as the upright type, thecontaminant receptacle 70, as illustrated inFIG. 4 , is substantially horizontally mounted to and separated from thecleaner body 30. - The
contaminant receptacle 70 may be formed in a substantially rectangular tank shape with a closed top end as illustrated inFIG. 8 . Thecontaminant receptacle 70 comprises thecontaminant receptacle body 71 having thetop wall 72. A contaminant-enteringopening 73 corresponding to the contaminant-dischargingopening 57 of thecyclone unit 50 is formed at thetop wall 72 of thecontaminant receptacle body 71. Anouter projection 74 is formed to project outside thecontaminants receptacle body 71 around the contaminant-enteringopening 73 of thetop wall 72 of thecontaminant receptacle body 71. Theouter projection 74 is inserted in a space between the sealingprojection 61 and the contaminant-dischargingpipe 58 formed at the supportingwall 60 of thecyclone unit 50. Therefore, when thecontaminant receptacle 70 is connected with thecyclone unit 50, a connecting portion between theleading end 58 a of the contaminant-dischargingpipe 58 of thecyclone unit 50 and thecontaminant entering opening 73 of thecontaminant receptacle 70 is sealed by the sealingprojection 61. When a sealing member (not illustrated), such as a gasket, may be disposed inside the sealingprojection 61, that is, a space between the sealingprojection 61 and theouter projection 74, sealing efficiency is increased. Also, aninner projection 75 may be formed to project toward a bottom of thecontaminant receptacle body 71 at an inner surface of thetop wall 72 of thecontaminant receptacle body 71. Theinner projection 75 prevents contaminants collected in thecontaminant receptacle 70 from flowing backward through the contaminant-enteringopening 73. Also, the connectingprotrusion 76 is formed at an outer circumference of thetop wall 72 of thecontaminant receptacle body 71, and is inserted in the connectinggroove 62 of thecyclone unit 50. Therefore, when connecting thecontaminant receptacle 70 with thecyclone unit 50, the user is required to push and insert thecontaminant receptacle 70 into thecyclone unit 50. For this a lifting unit 90 (seeFIG. 3 ) may be disposed below thecontaminant receptacle 70 to cause thecontaminant receptacle 70 to move up and down. The liftingunit 90 may be configured so that a cam and a lever cause thecontaminant receptacle 70 to move up and down. Conventional lifting units can be used as the lifting unit. Therefore, a detailed description of the liftingunit 90 will be omitted. - Furthermore, the
contaminant receptacle 70 includes ahandle 77 disposed at a side surface of thecontaminant receptacle body 71, abottom cover 78 that is disposed at a bottom end of thecontaminant receptacle body 71 and can be opened and closed, and a bottom cover opening unit 80 (seeFIGS. 3-6 ) to selectively open or close thebottom cover 78. - The
bottom cover 78 is connected with a sidewall of thecontaminant receptacle body 71 by hinges 79. In this exemplary embodiment, as illustrated inFIGS. 8 and 9 , thebottom cover 78 is connected with the bottom end of thecontaminant receptacle body 71 by two hinges 79. - Referring to
FIG. 3 , the bottomcover opening unit 80 includes a fixinghook 82, a fixingprotrusion 83, arelease lever 81, and anelastic member 85. The fixinghook 82 is disposed at a side of thebottom cover 78, that is, a side of thebottom cover 78 opposite to the side thereof in which thehinges 79 are disposed. The fixingprotrusion 83 is disposed at the bottom end of thecontaminant receptacle body 71 so that it can be connected with the fixinghook 82 when thebottom cover 78 is closed. Therelease lever 81 is formed to release a leading end of the fixinghook 82 from the fixingprotrusion 83. Theelastic member 85 biases elastically therelease lever 81 upward. - The
release lever 81 may be disposed inside thehandle 77 so that it can move along thehandle 77. That is, thehandle 77 may be formed to support and guide the movement of therelease lever 81 therethrough. Arelease button 84 is formed at an end of therelease lever 81. Theelastic member 85 is disposed underneath therelease button 84. That is, theelastic member 85 is disposed between therelease button 84 and thehandle 77 as illustrated inFIG. 3 . Abottom end 81 a of therelease lever 81 is formed to push the fixinghook 82 as illustrated inFIG. 3 . Therefore, when therelease button 84 is pushed, therelease lever 81 is moved downward along thehandle 77. When therelease lever 81 is moved downward, thebottom end 81 a of therelease lever 81 presses the fixinghook 82, so the fixinghook 82 is released from the fixingprotrusion 83. When the fixinghook 82 is released from the fixingprotrusion 83, thebottom cover 78 rotates downward on thehinges 79 by its own weight so that the bottom of thecontaminant receptacle 70 is opened (seeFIG. 9 ). On the other hand, when the user takes away the force to press therelease button 84, therelease button 84 is moved upward by theelastic member 85. At this time, when the user closes thebottom cover 78, the fixinghook 82 is caught on the fixingprotrusion 83 of thecontaminant receptacle body 71 so that thebottom cover 78 is fixed to the contaminant receptacle body 71 (seeFIG. 8 ). - Hereinafter, operation of the cyclone
contaminant collecting apparatus 40 for a vacuum cleaner having the structure as described above according to an exemplary embodiment of the present disclosure will be explained with reference to the accompanying figures. - First, the case will be explained when the
vacuum cleaner 1 having the cyclonecontaminant collecting apparatus 40 according to an exemplary embodiment of the present disclosure is used as the upright type as illustrated inFIG. 1 . - When the
vacuum cleaner 1 is used as the upright type, thefirst sidewall 31 of thecleaner body 30 is fixed to the body-mountingportion 11 of thesuction nozzle 10, so thecleaner body 30 moves integrally with thesuction nozzle 10. At this time, theextension pipe 21 and theflexible hose 22 of theextension pipe assembly 20 is fixed to an outer surface of thesecond sidewall 32 of thecleaner body 30. - In this state, when the vacuum generator (not illustrated) operates to generate a suction force, contaminants and air are drawn in the
suction nozzle 10, and then moved to thecleaner body 30 through theextension pipe assembly 20. - The contaminants and air, which arrive at the
cleaner body 30, enter inside thecyclone body 51 of thecyclone unit 50 through the air-entering pipe 52 (arrow A). The contaminants and air, as arrow B illustrated inFIG. 3 , whirl around the longitudinal center axis CL of thecyclone unit 50 substantially horizontal with respect to the surface to be cleaned 3. While whirling, the contaminants are separated from the air and are discharged into thecontaminant receptacle 70 through the contaminant-dischargingopening 57 formed at the cyclone body 51 (arrow C). At this time, the contaminant-dischargingopening 57 is located at the lower portion of thecyclone unit 50 so that the contaminants separated in thecyclone unit 50 are smoothly discharged. On the other hand, clean air having the contaminants removed is discharged toward thesecond sidewall 32 of thecleaner body 30 through the air-discharging pipe 53 (arrow D). The clean air discharged toward thesecond sidewall 32 moves to the vacuum generator through the dischargingduct 36 disposed at the second sidewall 32 (arrow E). - When emptying the contaminants collected in the
contaminant receptacle 70, the user moves thecontaminant receptacle 70 downward to be separated from thecyclone unit 50. After that, the user grabs thehandle 77 of thecontaminant receptacle 70, and then takes out thecontaminant receptacle 70 in a direction parallel to the surface to be cleaned as arrow H1 illustrated inFIG. 4 . After that, when the user presses therelease button 84 disposed on thehandle 77, therelease lever 81 moves downward to cause the fixinghook 82 to be released from the fixingprotrusion 83. When the fixinghook 82 is released from the fixingprotrusion 83, thebottom cover 78 is opened on thehinges 79 as illustrated inFIG. 9 so that the contaminants collected in thecontaminant receptacle 70 drop to be discharged. Then, when the user pushes upward and closes thebottom cover 78, the fixinghook 82 is caught on the fixingprotrusion 83 so that thebottom cover 78 is fixed to thecontaminant receptacle body 71. - After that, the user inserts the
contaminant receptacle 70 in the direction parallel to the surface to be cleaned 3 as arrow H2 illustrated inFIG. 4 so that thecontaminant receptacle 70 is positioned below thecyclone unit 50. Then, the user operates the liftingunit 90 so that thecontaminant receptacle 70 is moved upward and connected with thecyclone unit 50. At this time, theouter projection 74 and the connectingprotrusion 76 formed at thetop wall 72 of thecontaminant receptacle 70 are inserted into the sealingprojection 61 and the connectinggroove 62 formed at the supportingwall 60 of thecyclone unit 50, respectively. - When the
vacuum cleaner 1 having the cyclonecontaminant collecting apparatus 40 according to an exemplary embodiment of the present disclosure is used as the upright type, the contaminants separated in thecyclone unit 50 are smoothly discharged through the contaminant-dischargingopening 57, and the contaminants collected in thecontaminant receptacle 70 does not flow backward to thecyclone unit 50. - Next, the case will be explained when the
vacuum cleaner 1 having the cyclonecontaminant collecting apparatus 40 is used as the canister type as illustrated inFIG. 2 . - When the
vacuum cleaner 1 is used as the canister type, thecleaner body 30 is separated from thesuction nozzle 10, and is positioned on the surface to be cleaned 3. At this time, thesecond sidewall 32 of thecleaner body 30 becomes the bottom surface. Therefore, the cyclonecontaminant collecting apparatus 40 is rotated by approximate 90 degrees compared as thevacuum cleaner 1 is used as the upright type. Thesuction nozzle 10 is connected with thecleaner body 30 via theextension pipe assembly 20. At this time, the user grabs thegrip 23 of theextension pipe assembly 20 and moves thesuction nozzle 10 to clean. - When the vacuum generator is operated to generate a suction force, contaminants and air drawn-in the
suction nozzle 10 move to thecleaner body 30 via theextension pipe assembly 20. - The contaminants and air, having arrived at the
cleaner body 30, enter inside thecyclone body 51 of thecyclone unit 50 via the air-entering pipe 52 (arrow A′). The contaminants and air entering thecyclone body 51, as arrow B′ illustrated inFIG. 5 , whirl around the longitudinal center axis CL of thecyclone unit 50 substantially vertical with respect to thesecond sidewall 32 of thecleaner body 30, that is, with respect to the surface to be cleaned 3. While whirling, the contaminants are separated from the air and are discharged to thecontaminant receptacle 70 through the contaminant-dischargingopening 57 formed at the upper portion of the cyclone body 51 (arrow C′). At this time, the separated contaminants are whirled along thecyclone body 51 and moved upward by centrifugal force, thereby being smoothly discharged to thecontaminant receptacle 70 through the contaminant-dischargingopening 57. On the other hand, clean air having the contaminants removed is discharged toward thesecond sidewall 32 of thecleaner body 30 through the air-discharging pipe 53 (arrow D′). The clean air discharged toward thesecond sidewall 32 moves to the vacuum generator through the dischargingduct 36 disposed at the second sidewall 32 (arrow E′). - When emptying the contaminants collected in the
contaminant receptacle 70, the user moves thecontaminant receptacle 70 in a direction opposite to thecyclone unit 50 to be separated from thecyclone unit 50. After that, the user grabs thehandle 77 of thecontaminant receptacle 70, and then, takes out thecontaminant receptacle 70 in a direction vertical to the surface to be cleaned 3 as arrow V1 illustrated inFIG. 6 . At this time, since thecontaminant entering opening 73 is formed at a position farthest away from the bottom of thecontaminant receptacle 70, that is, the highest position from thesecond sidewall 32 of thecleaner body 30 as illustrated inFIG. 5 , the contaminants collected in thecontaminant receptacle 70 does not leak almost through thecontaminant entering opening 73 during separation of thecontaminant receptacle 70. - Thereafter the user holds the
contaminant receptacle 70 so that thebottom cover 78 of thecontaminant receptacle 70 faces downward, the user presses therelease button 84 disposed on thehandle 77. A user actuates therelease lever 81 and thereby causes the fixinghook 82 to be released from the fixingprotrusion 83 so that thebottom cover 78 is opened downward on thehinges 79. When thebottom cover 78 is opened, the contaminants collected in thecontaminant receptacle 70 drop to be discharged by their own weight. Then, when the user closes thebottom cover 78, the fixinghook 82 is caught on the fixingprotrusion 83 so that thebottom cover 78 is fixed to thecontaminant receptacle body 71. - After that, the user mounts the
contaminant receptacle 70 to thecleaner body 30 in the direction vertical with respect to thesecond sidewall 32 of thecleaner body 30 as arrow V2 illustrated inFIG. 6 . Then, the user operates the liftingunit 90 so that thecontaminant receptacle 70 is moved toward thecyclone unit 50, thereby completing mounting of thecontaminant receptacle 70. At this time, theouter projection 74 and the connectingprotrusion 76 formed at thetop wall 72 of thecontaminant receptacle 70 are inserted into the sealingprojection 61 and the connectinggroove 62 formed at the supportingwall 60 of thecyclone unit 50, respectively. - When the
vacuum cleaner 1 having the cyclonecontaminant collecting apparatus 40 is used as the canister type, the contaminants separated in thecyclone unit 50 are smoothly discharged through the contaminant-dischargingopening 57, and the contaminants collected in thecontaminant receptacle 70 does not flow backward to thecyclone unit 50. - Therefore, in the
vacuum cleaner 1 having the cyclonecontaminant collecting apparatus 40, even when the user changes thevacuum cleaner 1 used as the upright type into the canister type or changes thevacuum cleaner 1 used as the canister type into the upright type, the contaminants collected in thecontaminant receptacle 70 does not flow backward to thecyclone unit 50. Also, when the user separates thecontaminant receptacle 70 from thecleaner body 30, the contaminants collected in thecontaminant receptacle 70 does not leak. - With the cyclone contaminant collecting apparatus for the
vacuum cleaner 1, when the position of the cleaner body is changed so that the vacuum cleaner is turned from the upright type to the canister type or the contrary, the contaminants collected in the contaminant receptacle do not flow backward to the cyclone unit of the cyclone contaminant collecting apparatus. - Furthermore, when the user separates the contaminant receptacle from the cleaner body, the contaminants does not leak from the contaminant receptacle.
- Therefore, the cyclone contaminant collecting apparatus for a
vacuum cleaner 1 can be used in vacuum cleaners that can be used both as the canister type and the upright type - While several embodiments of the present disclosure have been described, additional variations and modifications of the embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims shall be construed to include both the above embodiments and all such variations and modifications that fall within the spirit and scope of the invention.
