  Hereinafter, the structure of the vacuum cleaner which concerns on 1st Embodiment of this invention is demonstrated based on FIGS. 1-4.

  The vacuum cleaner 1 has three main parts. The floor suction tool 10, the handle column 20 attached to the floor suction tool 10 so as to be tiltable, and the main body unit 30 supported by the handle column 20 in such a manner that the distance to the floor suction tool 10 can be changed. .

  The floor suction tool 10 has a suction port facing the floor, and a power brush (not shown) that is disposed inside the suction port and that is rotated by a motor to scrape dust from the floor. It is supported on the floor by a sliding raised cloth 11 and two rear wheels 12 provided at both ends of the lower front.

  The handle column 20 is attached to the floor suction tool 10 so that the angle can be changed in an angle range near 90 ° from the upright position shown in FIG. A handle 21 is provided at the upper end of the handle column 20. Since the handle column 20 supports the main body 30 on the front side, if the handle column 20 is set to the upright posture of FIG. 1, the handle column 20 stands stably in that posture. This is the posture when the electric vacuum cleaner 1 is stored. This posture is maintained by a locking device (not shown) provided between the handle column 20 and the floor suction tool 10, and a lock release button 22 is provided on the side surface near the lower end of the handle column 20.

  The main body 30 has a cylindrical shape, and a dust collecting portion 31 is detachably connected to the lower portion. The dust collection unit 31 incorporates known dust collection elements such as a cyclone dust collection unit and a filter unit. An electric blower (not shown) and a battery (not shown) serving as a power source for the electric blower are housed inside the main body 30 so as to be positioned above the dust collecting portion 31. A switch 32 for turning on and off the electric blower is provided on the upper surface of the main body 30.

  The main body 30 is attached to the handle column by fitting the sheath 33 formed at the rear part to the handle column 20. The sheath 33 is longer than the main body 30 in the vertical direction, and the upper end and the lower end protrude from the main body 30. The sheath 33 is slidable with respect to the handle column 30 in the axial direction, but is fitted so as not to rotate around the axis.

  A lock device 40 is provided between the handle column 20 and the main body 30 to fix the main body 30 at a selected position. The locking device 40 is provided inside the sheath portion 33 with a plurality of notches 41 carved at predetermined intervals along the axial direction on the rear surface of the handle column 20, and engages with one of the notches 41 by the force of a spring. A latch not shown and a lock release knob 42 provided on the rear surface of the sheath 33 are configured. When the lock release knob 42 is pulled up, the latch is released from the notch 41 and the main body 30 can be slid.

  It is the telescopic hose 34 that connects the floor suction tool 10 and the main body 30 and allows the floor suction tool 10 and the dust collecting part 31 to communicate with each other. The telescopic hose 34 is housed inside the handle column 20 and is connected to an elbow-shaped main body side connecting pipe 35 protruding from the dust collecting portion 31. An incision 23 for moving the main body side connecting pipe 35 along the axial direction of the handle column 20 is formed on the front side of the handle column 20. In addition, the expansion / contraction hose 34 used here is a bellows type, and the wrinkles seen from the incision part 23 are horizontal as shown in FIG.

  The vacuum cleaner 1 is used as follows. From the storage state of FIG. 1, the lock release button 22 is first pressed so that the handle column 20 can be freely tilted. Holding the handle 21 of the handle column 20 in this state with one hand, the switch 32 is turned on to drive the electric blower. Then, an air flow entering the dust collecting portion 31 from the floor suction tool 10 through the telescopic hose 34 is generated, and the dust on the floor is sucked into the dust collecting portion 31 by the air flow and collected. Since the distance between the main body 30 and the floor suction port 10 is short and the center of gravity of the vacuum cleaner 1 is on the lower side, the operation of reciprocating on the floor can be easily performed.

  When cleaning the gap of furniture or under the bed, etc., the lock by the locking device 40 is released, the main body 30 is slid, and the floor suction tool 10 and the main body 30 are moved as shown in FIGS. Increase the distance. As a result, the main body 30 does not get in the way when the floor suction port 10 is placed under a gap in the furniture or under the bed, and the target location can be sufficiently cleaned.

  When the cleaning is completed, the switch 32 is operated to stop the electric blower, and the handle column 20 is brought upright. In the state of FIG. 3, the center of gravity comes up and is unstable, so it is better to store the main body 30 in a lowered state as shown in FIG. 1.

A spiral type shown in FIG. 5 can also be used for the telescopic hose 34. As shown in FIG. 6, the wrinkles seen from the incision 23 are oblique. Another embodiment of the present invention is shown in FIG. Components that are functionally common to the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and description thereof is omitted.

  A second embodiment of the present invention is shown in FIGS. In the second embodiment, the incision 23 of the handle column 20 is provided with a shutter 24 for covering the telescopic hose 34. The shutter 24 has a shape in which a certain angle portion is cut out from a pipe having a circular cross section, and is inserted into a gap between the handle column 20 and the telescopic hose 34 as shown in FIGS. The shutter 24 has an inclined portion 25 at the upper end against which the main body side connecting pipe 35 hits, and is always urged to a closed position shown in FIG. 9 by a spring (not shown).

  When the main body 30 is separated from the floor suction tool 10 most, that is, when the latch of the locking device 40 is engaged with the notch 41 farthest from the floor suction tool 10, the incision 23 is exposed to the maximum extent. Become. At this time, the main body side connecting pipe 35 is positioned at the top of the incision 23 as shown in FIG. 8 and does not press the shutter 24. The shutter 24 is fully closed and covers the telescopic hose 34 as shown in FIG. When the main body portion 30 is slid downward, the main body side connecting pipe 35 pushes the slope portion 25, and the shutter 24 is pushed open as shown in FIG. If the main body portion 30 is lowered to the lowest position, the incision portion 23 is covered with the sheath portion 33, so that the telescopic hose 34 cannot be seen from the outside even though the shutter 24 is open. That is, if the main body 30 is raised to the top or lowered to the bottom, the telescopic hose 34 is covered.

  A third embodiment of the present invention is shown in FIGS. In 3rd Embodiment, in order to make the suction tool 10 for floors and the dust collecting part 31 communicate, the internal space of the handle support | pillar 20 is utilized to the middle, and the expansion-contraction hose 34 is used from the middle.
