Definitions

  • the present invention relates to an upright vacuum cleaner. More particularly, the present invention relates to a locking/unlocking device for a dust-collector that is removably mounted in an upright vacuum cleaner, and an upright vacuum cleaner having the same.
  • An upright vacuum cleaner comprises a cleaner body having a motor as a vacuum generating source, a suction nozzle disposed under the cleaner body to draw in dust-laden air therethrough, a dust-collector to separate dust particles from the air drawn in through the suction nozzle, collect the separated dust particles and discharge a cleaned air to the outside.
  • the dust-collector is removably mounted in a mounting portion of the cleaner body.
  • a user removes the dust-collector from the cleaner body to empty the dust-collector or repair the cleaner body. Meanwhile, when the vacuum cleaner cleans a large cleaning area, the dust-collector must be securely mounted in the cleaner body to be able to perform a cleaning operation smoothly. Therefore, a locking/unlocking device for the dust-collector is necessarily required.
  • the conventional dust-collector is secured to the cleaner body by a screw.
  • an extra tool is required to dismount the dust-collector from the cleaner body, and it takes a large amount of time to drive or extract the screw. Therefore, a current upright vacuum cleaner has a lever formed on a cleaner body that can be simply operated to lock or unlock the dust-collector.
  • U.S. Patent No. 6,385,810 discloses a lever 124 pivotably disposed at an upper wall of a dirt cup chamber and a latch plate 100 pivoting vertically in cooperation with a cam groove 126 formed on a body of the lever 124 when the lever 124 pivots.
  • the locking/unlocking device disclosed in the '810 patent has a very complicated structure. Also, a cam sleeve 102 is additional required to pivotably secure the lever 124 to an upper wall of the dirt cup chamber. Due to the complicated structure, a manufacturing cost is inevitably increased.
  • U.S. Patent No. 6,735,816 discloses an operating lever 410 pivotably disposed at a lower wall of a dust-collecting chamber and a locking disk 420 pivotably connected with an upper portion of the operating lever 410.
  • the operating lever 410 and the locking disk 420 have cams 460, 470, respectively, such that the locking disk 420 is moved vertically as the operating lever pivots, and thereby locks or unlocks the dust-collecting chamber.
  • the '816 patent further discloses a suction passage 210 and a discharging passage 220 disposed at a side or an upper portion of the dust-collecting chamber. Therefore, tubes 140, 150 fluidly communicating with the suction passage 210 and the discharging passage 220 inevitably become elongated.
  • an upright vacuum cleaner has a suction passage and a discharging passage formed in a bottom of a dust-collector and thus has an air channel shortened.
  • the operating lever 410 and the locking disk 420 are disposed on the lower wall of the dust-collecting chamber, it is difficult to dispose the suction passage and the discharging passage on the lower surface of the dust-collecting chamber.
  • An aspect of the present invention is to provide a dust-collector locking/unlocking device having a simplified and compact structure, and an upright vacuum cleaner having the same.
  • the above aspect is achieved by providing a dust-collector locking/unlocking device to lock or unlock a dust-collector removably mounted in a cleaner body.
  • the dust-collector locking/unlocking device includes a first member having a first hook that is rotatably connected with the cleaner body, a manipulation lever that protrudes from an outer circumference of the first member so that the first member is rotatable by a user, and a second member disposed under the first member and having a second hook movably connected with guide cams formed on the first member.
  • the second member is a cover of the dust-collector.
  • the first member further includes first cam parts formed on the lowest surface of the first member, and the second member further includes second cam parts having a shape to be engaged with the first cam parts.
  • the second member further includes a fixing protrusion that is connected with the cleaner body and is movable up and down.
  • the first member further includes a first penetrating hole and a second penetrating hole through which the second hook and the fixing protrusion of the second member penetrate, respectively.
  • an upright vacuum cleaner including a cleaner body having a motor driving chamber, a suction nozzle connected with a lower portion of the cleaner body, a dust-collector removably mounted in the cleaner body, and a dust-collector locking/unlocking device to lock or unlock the dust-collector with respect to the cleaner body
  • the dust-collector locking/unlocking device comprising a first member rotatably connected with the cleaner body and having a manipulation lever, and a second member movably connected with a lower portion of the first member, wherein the second member moves up and down in cooperation with a cam movement of the first member when the manipulation lever is rotated, thereby locking or unlocking the dust-collector, and the second cover is a cover of the dust-collector.
  • the first member includes a first hook connected with an upper wall of the cleaner body, and first cam parts formed on a lower end of the first member
  • the second member includes a second hook movably connected with guide cams formed on the first member, second cam parts engaged with the first cam parts, and a fixing protrusion connected with the upper wall of the cleaner body and movable vertically.

  • FIG. 5 is a perspective view illustrating the second member 220 of FIG. 2 connected to the upper wall 112 of the front frame 115.
  • FIGS. 4 and 5 do not illustrate the front frame cover 116 (see FIG. 1 ) for the convenience of explanation.
  • the first member 210 comprises a first hook 211 rotatably connected with the upper wall 112 of the front frame 115, a manipulation lever 214 protruding from an outer circumference of the first member 210 for a user manipulation, guide cams 215, and first cam parts 216.
  • the first hook 211 upwardly protrudes from the center of the first member 210 towards the upper wall 112 of the front frame 115, and is rotatably positioned in a mounting hole 113 formed in the upper wall 112 (see FIGS. 4 and 5 ).
  • the first hook 211 comprises a pair of body parts 212 penetrating through the mounting hole 113 and a hook part 213 depending from each body part 212.
  • the body parts 212 resiliently depend from first member 210 so that the first hook 211 can be biased inward toward one another while hook parts 213 are inserted into mounting hole 113, but can bias outward from one another so that hook parts 213 are hooked onto an upper end of the mounting hole 113.
  • the first hook 211 servers as a rotation axis for the first member 210 within mounting hole 113.
  • the first member 210 is hung to the upper wall 112 of the cleaner body 110 by the first hook 211, and it is rotatable on the first hook 211 but not movable vertically. Accordingly, if a user moves the manipulation lever 214 in the arrow direction A or B, the first member 210 is rotated on the first hook 211 in the direction A or B.
  • the guide cams 215 are hooked by second hooks 221 of the second member 220, and, as shown in FIGS. 2 and 7 , the guide cams 215 are upwardly inclined in one direction. Accordingly, when the first member 210 is moved in the direction A, the second hooks 221 slide upwardly along the guide cams 215. As a result, the second member 220 is moved upwardly, i.e., in the direction C of FIG. 7 .
  • the first cam parts 216 are formed on the lowest surface of the first member 210 and have a shape corresponding to second cam parts 225 of the second member 220. More specifically, as shown in FIG. 3 , the first cam parts 216 are downwardly inclined in the direction B, whereas the second cam parts 225 are upwardly inclined in the direction B. If the manipulation lever 214 is moved in the direction B, the first cam parts 216 are engaged with the second cam parts 225, thereby downwardly pressing the second cam parts 225. Accordingly, the second member 220 is moved downwardly and thereby securely locks the dust-collector 130 (see FIG. 1 ).
  • the first member 210 has a pair of first penetrating holes 217 and a second penetrating hole 218 to pass the second hooks 221 and a fixing protrusion 224 therethrough, respectively.
  • the second member 220 comprises the second hooks 221 movably hooked onto the guide cams 215, the second cam parts 225 engaged with the first cam parts 216 of the first member 210, and the fixing protrusion 224 fixed to the upper wall 112 of the front frame 115.
  • the second hooks 221 upwardly protrude from the bottom of the second member 220, and each comprise a body part 222 passing through the first penetrating holes 217 of the first member 210 and hook parts 223 hooked onto the guide cams 215.
  • the second hooks 221 upwardly slide along the guide cams 215 and consequently the second member 220 is moved upwardly, i.e., in the direction C (see FIG. 7 ).
  • the fixing protrusion 224 upwardly protrudes from the bottom of the second member 220 and is inserted into a fixing hole 114 of the upper wall 112 of the front frame 115 (see FIGS. 4 and 5 ).
  • the fixing protrusion 224 is movable vertically with respect to the fixing hole 114.
  • the second member 220 is rotatable horizontally in cooperation with the first member 210, but its rotational movement is restricted by the fixing protrusion 224 and the second penetrating hole, and thus the second member 220 maintains its rotational position within the length of the second penetrating hole.
  • the second cam parts 225 are engaged with the first cam parts 216 of the first member 210.
  • the second cam parts 225 are upwardly inclined in the direction B.
  • the first and the second cam parts 216, 225 are brought into contact such that the first cam parts 216 downwardly presses the second cam parts 225.
  • the second member 220 is moved downwardly in the direction D.
  • the dust-collector locking/unlocking device 200 is disposed on the upper portion of the dust-collector 130, there is no limitation to arrangements of a suction passage and a discharging passage of the dust-collector 130.
  • a suction passage and a discharging passage have to be disposed a side portion or an upper portion of a dust-collector, but according to the present invention, it is possible to dispose the suction passage and the discharging passage on the bottom of the dust-collector 130.
  • the second member 220 servers as a cover to cover an upper portion of the dust-collector 130 (see FIG. 1 ). Since no additional cover is required to cover the dust collector 130, the volume of the dust-collector 130 can be reduced and also the vacuum cleaner employing the dust-collector 130 can be compact-sized.
  • a user rotates the manipulation lever 214 of the first member 210 in one direction, i.e., in the direction A to remove the dust-collector 130 from the cleaner body 110 to empty or repair the dust-collector 130.
  • Rotation of the manipulation lever 214 in the direction A causes the first member 210 to be rotated on the first hook 211 in the direction A so that the second hooks 221 upwardly slide along the guide cams 215 causing the second member 220 to move upwardly in the direction C.
  • the second member 220 is disjoined and separated from the upper end of the dust-collector 130 by a predetermined distance. To this end, a user easily removes the dust-collector 130 from the cleaner body 110 by simply holding and drawing out the dust-collector 130.
  • the user rotates the manipulation lever 214 in the opposite direction i.e., in the direction B.
  • Rotation of the manipulation lever 214 in the direction A causes the first member 210 to be rotated in the direction B so that the second hooks 221 downwardly slide along the guide cams 215.
  • the second member 220 is moved downwardly due to a self-weight.
  • the second cam parts 225 of the second member 220 are brought into contact with the first cam parts 216 of the first member 210 and thereby are downwardly pressed. Accordingly, the second member 220 is further moved in the direction D and, thus its lowest surface contact-presses the upper portion of the dust-collector 130, thereby securely locking the dust-collector 130 to the cleaner body 110.
  • the dust-collector locking/unlocking device 200 is able to lock or unlock the dust-collector 130 with respect to the cleaner body 110 by simply rotating the manipulation lever 214 in one direction. Therefore, no extra tool is required and the dust-collector 130 is easily removed from the cleaner body 110.
  • the dust-collector locking/unlocking device 200 has a simplified structure integrating the first and the second members 210, 220, the dust-collector 130 is simply mounted or removed from the cleaner body 110.
  • the simplified structure reduces the number of parts and simplifies an assembling process, which results in a cont-saving effect.
  • the dust-collector locking/unlocking device 200 is disposed on the upper portion of the dust-collector 130, there is no limitation in forming the suction passage and the discharging passage in the dust-collector 130. Also, the second member 220 of the dust-collector locking/unlocking device 200 serves as a cover to cover the dust-collector 130, an extra cover is not required. Accordingly, the volume of the dust-collector 130 can be reduced and thus the vacuum cleaner can be compact-sized.
