FIG. 9 is a longitudinal sectional view along the width direction, FIG. 9 is a sectional view taken along line IX-IX of the vacuum cleaner in FIG. 7, FIG. 10 is a sectional view taken along line XX of the vacuum cleaner in FIG. 7, and FIG. FIG. 12 is an explanatory cross-sectional view showing a state in which a floor cleaning channel opening / closing mechanism is opened when cleaning the floor of the vacuum cleaner, and FIG. It is sectional explanatory drawing which shows the state which closes the flow path opening / closing mechanism for hand cleaning when performing cleaning.

The upright type vacuum cleaner shown in FIGS. 1 to 8 includes a suction tool main body 1, a cleaner main body 2 swingably supported on an upper portion of the suction tool main body 1, a grip portion 3, It comprises a distal end pipe 4 fixed to the grip portion 3, a flexible hose 5, and a rotating pipe 6.

The distal end of the distal pipe 4 is attached to the cleaner body 2.
And is detachably supported by being inserted into the cylindrical tip-side pipe support portion 10. Moreover, the grip part 3 is connected to the dust collecting chamber 7 of the cleaner body 2 via a flexible hose 5 disposed on the rear side of the grip part 3.

In the vacuum cleaner of the present embodiment, in a use state in which normal floor cleaning is performed, suction is performed from the suction tool main body 1 into the dust collecting chamber 7 through the main body side flow path 8. When cleaning the hand, pull out the tip side pipe 4 of the grip part 3 from the cleaner body 2 and hold the grip part 3 from the tip of the tip side pipe 4 to remove dust or dust from the ceiling, wall, or gap. Aspirate. Therefore, both the floor cleaning and the hand cleaning can be performed while the handle 3a of the grip portion 3 is gripped, so that the cleaning workability is improved.

Further, since the handle 3a is provided so as to be separated from the flow path inside the grip portion 3, it is easy to hold by hand.

In addition, the flexible hose 5 is provided with the grip 3
Since the flexible hose 5 is disposed so as to cover almost the entire rear side, the state is clear when viewed from the front, and the appearance is improved.

The suction tool main body 1 of the present embodiment includes a front wheel 1
6 and a rear wheel 17 so that the floor can be rolled. Further, the suction tool main body 1 has a built-in electric blower 18 and a belt 2 wound around a shaft of the electric blower 18.
0 is provided with a rotating brush 19 rotated through.

The cleaner main body 2 has a detachable dust collecting portion 29. The dust collecting portion 29 has a dust collecting chamber 7 formed inside a dust collecting chamber outer shell 30, and has a mesh-shaped pre-filter 31; H
A double filter including a main filter 32 made of an EPA filter or the like is provided.

At the upper part of the cleaner body 2, there is provided a tip side pipe support 10 for detachably supporting the tip side pipe 4. The tip pipe support 10 has a tubular shape and is formed integrally with the cleaner body 1. Therefore, as shown in FIGS. 1 and 2 and FIGS. 11 to 12, by inserting the distal end pipe 4 into the distal end pipe support portion 10, the appearance is further improved and the steel distal end pipe 4 and its support are further improved. Due to the double structure including the part 10, the connection state between the grip part 3 and the cleaner body 2 at the time of floor cleaning becomes stronger.

The grip portion 3 is formed of a hollow cylinder, and a handle 3a is formed at an upper end. The distal end pipe 4 and the flexible hose 5 are connected via the grip portion 3. In addition, the grip portion 3 is provided at the distal end side pipe support portion 1.
It is detachably connected to the unit 0 by a grip unit attaching / detaching button 12 having a hook 12a.

Therefore, when the user wants to use the distal end pipe 4 at the time of hand cleaning, the user can use the grip portion attaching / detaching button 12.
, And can be easily used simply by pulling out the grip portion 3. When the distal end pipe 4 is stored, the hook 12 can be inserted simply by inserting the distal end pipe 4 into the support portion 10.
a is engaged with the support 10 and is automatically locked.

The flexible hose 5 has a lower end connected to a substantially L-shaped connecting pipe 21 provided on the cleaner body 2 and an upper end connected to the grip portion 3. Connecting pipe 21
Is provided near the lower rear end of the cleaner main body 2 and communicates with the main body side channel 8 inside the cleaner main body 2.

As shown in FIGS. 3 and 4, when hand cleaning is performed using the distal end pipe 4, the grip 3,
After passing through the hand cleaning channel 9 composed of the rotating pipe 6, the flexible hose 5 and the connecting pipe 21, the dust is collected in the dust collection chamber 7 through the main body side channel 8.

The flexible hose 5 is connected to the grip portion 3 via a rotating tube 6 rotatably connected to the grip portion 3, and the rotating tube 6 is easily connected to the grip portion 3. Since it can rotate, the load on the user can be reduced. Therefore, the ceiling and floor can be easily cleaned.

Also, as shown in FIGS. 1 and 2, when the vacuum cleaner is stored and transported, the flexible hose 5 can be locked in a state where the rotary tube 6 is bent downward so that the flexible hose 5 can be locked. As it does not protrude or swing, it is convenient for storage and transportation.

4 and 11 show the suction tool body 1.
As shown in FIG. 1, a floor cleaning channel opening / closing mechanism 1 provided with a rotary pipe 22 that swings together with the cleaner main body 2.
3 is built-in. In the case of hand cleaning shown in FIGS. 3 and 4 in which the cleaner body 2 is set up substantially vertically, since the rotary pipe 22 is closed with respect to the internal space of the suction tool body 1, There is no suction from the suction tool main body 1, and therefore, hand cleaning can be performed with high suction efficiency.

FIG. 5 shows a vacuum cleaner according to the present embodiment.
As shown in FIG.
Since various attachments such as the nozzle 4a, the gap nozzle 14b, the flat nozzle 14c, and the round brush 14d are provided, when performing hand cleaning, by attaching these attachments to the tip of the tip-side pipe 4, the Also, cleaning work at high places and narrow gaps can be performed.

Next, with reference to FIGS. 7 to 10, the intake / exhaust flow path of the vacuum cleaner according to the present embodiment will be described in further detail.

The air sucked together with dust from the suction tool main body 1 during floor cleaning rises through the main body side flow path 8 extending vertically inside the cleaner main body 2, and from the outlet 8 a to the inside of the dust collection chamber 7. Will be introduced. Inside the dust collection chamber 7, the air
It is filtered through the pre-filter 31 and the main filter 32. At this time, the large dust is removed from the pre-filter 31.
The dust is collected in a space between the dust collecting chamber outer shell 30 and the pre-filter 31, and fine dust and dust are collected on the surface of the main filter 32.

The air purified inside the dust collecting chamber 7 descends inside the dust collecting chamber 7 and is sent to the electric blower 18 in the suction tool main body 1 through the blower connecting pipe 25 and then to the exhaust passage 2.
6 and is exhausted to the outside through an exhaust port 28 formed on the side surface of the cleaner body 2 through an exhaust filter 28 such as a HEPA filter.

On the other hand, the air sucked together with the dust from the distal end pipe 4 at the time of hand cleaning,
The main body side flow path 8 passes through the hand cleaning flow path 9 including the grip portion 3, the rotation pipe 6, the flexible hose 5, and the connection pipe 21.
To join. The subsequent flow is the same as in the case of floor cleaning described above.

[0030]

According to the present invention, since the flexible hose is disposed on the rear side of the grip portion, the appearance becomes very good when viewed from the front. Therefore, even when the cleaner is not used, it is highly aesthetic even if it is placed in one corner of the room.

In addition, since the distal end pipe is fixed to the grip in advance, hand cleaning can be easily performed while holding the grip by not only cleaning the floor but also removing the grip from the cleaner body. Therefore, cleaning workability can be greatly improved.
