Definitions

  • the present disclosure relates to a vacuum cleaner, and more particularly, to a dust collecting apparatus for a vacuum cleaner, which collects dust from a surface to be cleaned along with air drawn-in through a suction nozzle using a suction force generated from a suction motor, and discharges dust-laden air to the outside of the vacuum cleaner.
  • dust collecting apparatuses for vacuum cleaners are divided into dust collecting apparatuses using dust bags and bag less dust collecting apparatuses in which dust bins are used semi-permanently.
  • Modern vacuum cleaners mainly include bagless dust collecting apparatuses in which dust bins are used semi-permanently.
  • bagless dust collecting apparatuses separate dust from a surface to be cleaned from drawn-in air using vacuum pressure generated between a suction nozzle and the surface to be cleaned, collect the separated dust, filter air from which the dust has been separated, and discharge the filtered air to the outside of vacuum cleaners.
  • a user may separate the dust collecting apparatus from a vacuum cleaner and empty the dust collecting apparatus. In this situation, if the dust collecting apparatus has a small size, a user may experience inconvenience due to the frequency at which the dust collecting apparatus needs to be emptied.
  • Japanese Laid Open Patent Application No. 54-99355 discloses a dust collecting apparatus including a dust compression plate to compress dust collected in a dust collecting chamber, and a plunger to operate the dust compression plate.
  • a plunger of a conventional dust collecting apparatus has a short length, a short compression motion during which dust is compressed using the dust compression plate causes a small amount of dust to be compressed, and accordingly, the degree of compression of the dust is small.
  • Japanese Laid Open Patent Application No. 54-51260 provides a dust collecting apparatus including a plunger having a relatively long length in order to increase the degree of compression of dust collected in a dust collecting chamber.
  • the plunger is disposed perpendicular to a dust compression plate regardless of whether the plunger is used or not, so the dust collecting apparatus should include a separate supporting unit and a separate space disposed above a dust collecting unit in order to support the plunger. This causes the height of the dust collecting unit to increase. Accordingly, it is impossible to maintain a compact dust collecting unit.
  • an aspect of the present disclosure is to address at least the above problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a dust collecting apparatus for a vacuum cleaner, which can increase the dust compression motion for compressing dust so that the degree of compression of the dust can be maximized, while a dust collecting case can be maintained as compact as possible.
  • a dust collecting apparatus for a vacuum cleaner including a dust collecting unit, which is detachably mounted in a main body of the vacuum cleaner and comprises an inlet and an exhaust port, to separate dust from air flowing into the inlet, collect the separated dust and discharge air from which the dust has been separated to the exhaust port; a cover to open and close an upper part of the dust collecting unit; a dust compression plate which is capable of upward and downward movement inside the dust collecting unit; and a plunger which penetrates the cover, one end of the plunger being attached to the dust compression plate by a hinge mechanism; wherein the plunger enables the dust compression plate to move upwardly and downwardly when dust compression is being performed, and the plunger is retracted and folded down toward the cover about one end of the plunger when dust compression is not being performed.
  • the dust compression motion can be increased while the entire size of the dust collecting apparatus remains unchanged, so that the degree of compression of dust collected in the dust collecting unit and the space for collecting dust can increase, and thus there is no need to frequently empty the dust collecting unit.
  • the plunger may further comprise a grip part detachably coupled to the opposite end thereof.
  • a grip part detachably coupled to the opposite end thereof.
  • the grip part may be disposed on the same plane as the plunger so that the grip part may be prevented from protruding further than the plunger when the plunger is folded down.
  • a dust collecting apparatus according to an exemplary embodiment of the present disclosure comprises a dust collecting unit 10, a cover 20, a dust compression plate 30 and a plunger 40.
  • the dust collecting unit 10 comprises a dust collecting case 11, a cyclone chamber 13 and a dust collecting chamber 15.
  • the dust collecting case 11 includes an inlet (not shown) into which dust-laden air flows, and an exhaust port (not shown) through which air from which dust has been separated is discharged.
  • the cyclone chamber 13 is separated from the dust collecting chamber 15 by a cylindrical part 12, and fluidly communicates with the inlet (not shown) and exhaust port (not shown).
  • the cyclone chamber 13 includes an exhaust pipe 14a which has a height lower than that of the cylindrical part 12 and which fluidly communicates with the exhaust port (not shown).
  • a spiral guide 14b is disposed between the cylindrical part 12 and the exhaust pipe 14a to give a rotation force to air and dust flowing into the cyclone chamber 13.
  • the dust collecting chamber 15 corresponds to the area of the dust collecting case 11 excluding the cylindrical part 12, in which dust D is stored after being discharged from a dust discharge space 16 formed between an upper end of the cylindrical part 12 and a bottom surface of the cover 20, as shown in FIG. 3 .
  • the cover 20 is disposed above the dust collecting case 11 to seal the dust collecting case 11. When a user removes dust collected in the dust collecting case 11, the cover 20 is removed from the dust collecting case 11 so that the upper part of the dust collecting case 11 is open. Additionally, the cover 20 comprises a through hole 21 through which the plunger 40 penetrates at a position above the dust collecting chamber 15.
  • the dust compression plate 30 is disposed on the inside of the dust collecting chamber 15 so as to be able to ascend and descend inside the dust collecting chamber 15.
  • the dust compression plate 30 is substantially parallel to a bottom wall 11a of the dust collecting case 11, so that the dust compression plate 30 can compress dust D collected in the dust collecting chamber 15 while moving downward inside the dust collecting chamber 15.
  • a projection 31 coupled to the end of the plunger 40 adjacent to the dust compression plate 30 using a hinge pin 50a is formed on the upper surface of the dust compression plate 30.
  • the projection 31 has a common axis with the through hole 21 of the cover 20 and has a diameter or a thickness relatively smaller than the through hole 21, so that the plunger 40 can pass through the through hole 21.
  • One end of the plunger 40 is connected to the dust compression plate 30 by a hinge mechanism 50, and a grip part 41 is detachably screwed to the opposite end thereof, as shown in FIG. 2 .
  • the grip part 41 is disposed on the same plane as the plunger 40 is disposed, in order to prevent the grip part 41 from protruding from the top surface of the cover 20 further than the plunger 40.
  • FIG. 3 shows the dust collecting apparatus before dust is compressed
  • FIG. 4 shows the dust collecting apparatus while dust is being compressed.
  • the dust compression plate 30 is disposed above the top of the cylindrical part 12, that is, substantially close to the bottom surface of the cover 20, so that dust discharged through the dust discharge space 16 can be collected in the dust collecting chamber 15 without interference, as shown in FIG. 3 .
  • a user grasps the grip part 41 of the plunger 40 and swivels the plunger 40 about the hinge pin 50a by approximately 90° in direction A, so that the plunger 40 is perpendicular to the dust compression plate 30.
  • the plunger 40 may penetrate through the through hole 21 (referring to FIG. 2 ) and enter the dust collecting chamber 15, so that the dust compression plate 30 can move downwardly toward the bottom wall 11 a of the dust collecting case 11. Accordingly, the dust compression plate 30 can compress dust D collected in the dust collecting chamber 15.
  • the user can compress dust D multiple times by repeatedly raising and lowering the dust compression plate 30 using the grip part 41.
  • a relatively long dust compression motion can be ensured using the plunger 40 with a long length, and thus the degree of compression of the dust can be maximized.
  • Reference numeral H of FIG. 4 indicates the user's hand.
  • a user can completely pull out the plunger 40 from the dust collecting case 11 through the through hole 21 in a direction opposite direction B, using the grip part 41.
  • the user swivels the plunger 41 in a direction opposite direction A about the hinge pin 50a, using the grip part 41, so that the plunger 40 can be laid down adjacent to the cover 20.
  • the plunger 40 is laid down flat on the top surface of the cover 20.
  • a plunger to move a dust compression plate up and down is long so that the dust compression motion can be as long as possible, and thus the degree of compression of the dust can increase, thereby ensuring a wide space for dust collection.
  • a plunger may be kept laid down on top of the dust compression plate, so a separate space is not required to receive or support the plunger, and the dust collecting unit may have a low height.
