Description

    TECHNICAL FIELD
  • [0001]
    The present invention relates to a vacuum cleaner with an integrated handheld vacuum cleaner unit that includes a dust container detachably mounted on a body of the vacuum cleaner and configured to perform vacuum cleaning via air suction in a detached state.
  • BACKGROUND ART
  • [0002]
    According to shapes and usage postures, vacuum cleaners can be generally classified into a canister type vacuum cleaner, which provides convenience in corner cleaning and movement while allowing easy replacement of a brush or a nozzle, and an upright type vacuum cleaner, which provides convenience in storage and allows easy cleaning of a large space.
  • [0003]
    FIG. 1 is a perspective view illustrating a conventional vacuum cleaner. Referring to FIG. 1, the conventional vacuum cleaner generally includes a suction unit 11 which will be brought into close contact with a floor, a pipe 12 connected to the suction unit 11 and having a predetermined length, a handle 13 connected to the pipe 12, a hose 14 connected to the handle 13, and a body 20 connected to the handle 14.
  • [0004]
    The suction unit 11 is provided at a lower surface with wheels to suck up foreign matter while moving on the floor, and the pipe 12 and the handle 13 are used to move the suction unit 11 to desired locations.
  • [0005]
    The pipe 12 and the hose 14 serve to guide air containing foreign matter into the body 20, which in turn sucks the air containing the foreign matter and collects the foreign matter while discharging filtered air to an outside of the body 20.
  • [0006]
    FIG. 2 is a schematic cross-sectional view of the body shown in FIG. 1. The body 20 is provided at a front side with a hose attaching part 21 for coupling with the hose 14.
  • [0007]
    The body 20 has a dust collection unit 22 positioned in a central region and connected to the hose attaching part 21.
  • [0008]
    Specifically, the dust collection unit 22 includes a dust container 24 that is inserted into an accommodation part 23 defined in the central region of the body 20 and has a filter 25 to filter foreign matter.
  • [0009]
    The dust container 24 is provided at an upper side with a knob 26 and is separated from the accommodation part 23 by means of a separation button 27 formed on the knob 26.
  • [0010]
    At this time, a motor 28 is positioned adjacent the accommodation part 23 inside the body 20 and driven by power supplied via a power cable 29.
  • [0011]
    Therefore, when the motor 28 is driven by power, air containing foreign matter is drawn into the dust container 24 and passes through the filter 25 in the dust container 24, so that the foreign matter is filtered by the filter 25 and collected in the container 24 while filtered air is discharged outside the vacuum cleaner.
  • [0012]
    Then, when filled with the foreign matter, the dust container 24 is separated from the insertion groove 24 by pushing the separation button 27, and opened to remove the foreign matter by means of a separate button.
  • [0013]
    However, since such a vacuum container has the motor installed inside the body, it is necessary to move the body when performing the vacuum operation at several locations on the floor.
  • [0014]
    Therefore, the conventional vacuum cleaner has problems in that the overall body must be moved even for corner vacuuming or partial vacuuming, and in that, in the case where a power cable has a short length, it must be plugged again into a wall socket near a vacuuming location.

    When the rechargeable battery 69 is disposed in the assistant case 46, the accommodation part 52 and the rechargeable battery 69 of the assistant case 66 are provided with ground terminals 72 to contact each other, and such ground terminals 72 are connected to the power supply device 54 to charge the battery 69.
  • [0103]
    The filter 64 can be attached to various parts of the dust container 61 depending on dust collection methods, and is preferably disposed near the inlet port 61 a in the case where a dust bag is provided as the filter 64.
  • [0104]
    Further, when such a filter 64 is applied to a cyclone type vacuum cleaner, it is desirable that the filter 64 be located near the exhaust port 61 b.
  • [0105]
    Operation and effect of the vacuum cleaner according to the second embodiment of the present invention having such a configuration as described above are described hereinafter.
  • [0106]
    First, by pushing an operation button (not shown) with the power supply device 54 plugged into a wall socket, the motor assembly 53 is driven to force air containing foreign matter to be drawn into the dust container 61 through the hose 14, and air filtered through the filter 64 is discharged to the outside.
  • [0107]
    When the dust container 61 is separated from the accommodation part 52 of the body 50 by pushing a separation button 55 to use the dust container 61 as a carriable handy cleaner for vacuuming, the dust container 61 and the assistant driving unit 65 coupled to the dust container 61 by the hinge 71 are separated from the body 50.
  • [0108]
    In this state, the assistant driving unit 65 and the dust container 61 are coupled to each other such that the suction hole 66 a is located near the exhaust port 61 b of the dust container 61, and the assistant hose 14 a is connected to the inlet port 61 a of the dust container 61.
  • [0109]
    Then, by pushing an operation button (not shown), power is supplied to the assistant motor assembly 67 via the assistant power supply device 68 or 69, so that the assistant motor assembly 67 is driven.
  • [0110]
    In this way, as suction force is generated by the assistant motor assembly 67, air containing foreign matter is drawn into the assistant hose 14 a coupled to the inlet port 61 a.
  • [0111]
    Therefore, the user can perform vacuum cleaning while carrying the dust container 61 by gripping the knob 63 of the dust container 61.
  • [0112]
    At this time, if the power cable 68 is used as the assistant power supply device, it is plugged into the wall socket to supply power to the assistant motor assembly 67.
  • [0113]
    If the rechargeable battery 69 is used as the assistant power supply device, it is charged through the ground terminals 72 via the power supply device 54 and supplies power to the assistant motor assembly 67 in response to a signal from the operation button (not shown).
  • [0114]
