The floor suction device 4 is configured to be rotatable in a direction substantially perpendicular to the extension direction of the extension tube 3.

On the other hand, the charging stand 5 has a built-in charger (not shown) for charging the storage battery 13 built in the cleaner body 1, and has a rear surface on the upper surface side. A mounting portion 51 that is depressed according to the side shape is formed. Although not shown, the mounting portion 51 is provided with a charging outlet into which a charging plug of the cleaner body 1 is inserted.

As shown in FIG. 1, when the cleaner main body 1 is stored in a state of standing upright on the floor, the floor suction tool 4 is rotated in a direction substantially perpendicular to the extension direction of the extension pipe 3. When the vacuum cleaner main body 1 is placed on the charging stand 5 and stored, as shown in FIG. 2, the floor suction device 4 moves in the direction in which the extension pipe 3 extends. In order for the tip side to be in contact with the floor surface in the rotated state, the attachment position of the hook 31 of the extension tube 3 and the height of the mounting portion 51 of the charging stand 5 are set.

In the above configuration, when the storage state is set to a simple state during the cleaning or the like, as shown in FIG. 1, the cleaning is performed while the flexible hose 2, the extension pipe 3 and the floor suction tool 4 are connected. The machine main body 1 is set up so that the back side thereof faces down, and the hook 31 attached to the extension pipe 3 is inserted into the concave portion 17 formed on the bottom front side of the cleaner main body 1. At this time, the projections 3 formed on the tip end side of the hook 31
2 comes into contact with a front wheel 15 at the center of the bottom surface side of the cleaner body 1, and the floor suction tool 4 rotates in a direction substantially perpendicular to the extension pipe 3, so that the bottom surface contacts the floor surface. As shown in FIG. 1, it looks as if the cleaner main body 1 is supported by palms or feet. In this state, since the extension pipe 3 is integrated with the cleaner main body 1, the handle 22 formed on the hose joint 21 can be easily carried with one hand.

On the other hand, when the cleaner main body 1 is placed on the charging stand 5 to be in a storage state which also serves for charging, the cleaner body 1 in the simple storage state is formed on the hose joint portion 21. By holding the handle 22 with one hand and lifting it up, as shown in FIG. 2, the back side of the cleaner main body 1 is placed on the mounting portion 51 of the charging stand 5 formed in accordance with the shape of the cleaner body 1, thereby simplifying the drawing. The storage state as shown in FIG.
At this time, the floor suction tool 4 connected to the extension pipe 3 is rotated by its own weight in the extension direction of the extension pipe 3, and the bottom surface thereof is on the charging stand 5.
And the tip side contacts the floor surface.
When taking out from the stored state placed on the charging stand 5 for cleaning, hold the handle 22 formed on the hose joint portion 21 with one hand, lift it up, carry it to the place to be cleaned, and lower it on the floor or the like, By removing the extension pipe 3 from the cleaner body 1 and turning the cleaner body 1 to the bottom side, cleaning can be started immediately.

Meanwhile, a heavy storage battery 13 is built in the bottom side inside the vacuum cleaner main body 1, and as shown in FIG.
In the state shown in FIG. 2 and the extension pipe 3 is locked to the bottom side of the cleaner body 1, the cleaner body 1 easily falls down to the bottom side. In any state, the bottom side or the tip side of the floor suction tool 4 is in contact with the floor surface, so that the vacuum cleaner main body 1 and the extension pipe 3 integrated with the vacuum cleaner main body 1 are inclined. Falling can be effectively prevented. At this time, the protrusion 3 formed on the extension tube 3 abuts on the front wheel 15 of the cleaner body 1 to prevent the hook 31 of the extension tube 3 from coming off the cleaner body 1.

Also, in the present embodiment, focusing on the point that the floor suction tool 4 rotates, the simple storage state shown in FIG.
In any storage state of the storage state that also serves as charging,
Since the bottom side or the tip side of the floor suction tool 4 is configured to be in contact with the floor, the above operation and effect can be realized with a simple configuration.

Further, since the projection 32 of the extension tube 3 is configured to abut on the front wheel 15 originally provided in the cleaner body 1, a new structure is added to the cleaner body 1 side. It is not necessary and can be realized by a simple configuration in which the projection 32 is formed only on the extension tube 3 side.

Further, since only the cleaner body 1 is placed on the charging stand 5, it is not necessary to form a holding portion for a floor suction tool and an extension tube holding portion as described in the above-mentioned conventional publication, which is necessary for charging. Since only a minimal configuration is required, space can be saved and the configuration can be simplified.

In the above embodiment, the floor suction tool 4 is configured to be completely in contact with the floor surface.
In the state described above, even if the tip side of the floor suction tool 4 is slightly floating from the floor surface (close proximity state), if the cleaner body 1 is slightly inclined to the bottom side, the tip side of the floor suction tool 4 will be on the floor. Since the inclination of the cleaner main body 1 can be suppressed by contacting the surface, the same operation and effect as in the above embodiment can be obtained.

[0029]

As described above, according to the present invention, the locking portion of the extension pipe is engaged with the main body of the cleaner with the rear side of the main body of the cleaner standing upright, so that it can be mounted on the floor surface. The suction unit for floor is in contact with or close to the floor surface regardless of whether the main body of the vacuum cleaner is placed on the floor or the charging stand, while the storage unit is placed and stored on the charging stand. By arranging the vacuum cleaner at a position where it can be used, it is possible to improve the usability, realize a simple and space-saving storage state, and prevent the vacuum cleaner main body and the extension tube from falling over in the charged state.

The floor suction device is configured to be rotatable in a direction substantially perpendicular to the extension direction of the extension tube, and is used when the cleaner body is stored in an upright state on the floor surface. When the vacuum cleaner main body is placed in a state where it is turned upright on the charging stand with the bottom side contacting the floor surface while rotating in a direction substantially perpendicular to the extension direction of the extension pipe, the floor suction tool is With the configuration in which the distal end side is in contact with or close to the floor surface in a state where the extension tube is rotated in the extension direction, the above-described effect can be easily achieved by effectively utilizing the point where the floor suction tool rotates. It can be realized by the configuration.

Further, in the state where the locking portion is engaged with the cleaner main body, the extension tube has a second locking portion which engages with the cleaner main body from the side opposite to the engaging direction of the locking portion. Due to the formation, the engagement state of the extension tube with the cleaner body can be prevented from coming off.

In addition, since the second engaging portion is formed with a projection which engages with the front wheel of the cleaner body, an extension pipe is used to effectively use the front wheel originally provided in the cleaner body. It can be realized with a simple configuration in which a projection is formed only on the side.
