In this embodiment, the base main body case 3 is integrally fixed by screws (not shown). A plurality of casters 19 are attached to the outer surface of the main body case 3 so that the casters 19 can run on the floor, and a ball-shaped caster that does not interfere with the carrying is preferable.

The body case 3 and the lid case 4 are preferably formed by plastic molding by blow molding or foam molding, but a plurality of uneven portions 50 serving as component holding portions are provided on the inner side surface, and the inner body 10 and the like are provided. Applied parts can be stored in a fixed position or detachably stored. Numerals 20 and 21 are extension tubes, and numeral 22 is an applied suction mouth for a gap. 23 is a dust bag for replenishment, which are arranged at positions where they do not interfere with each other.

Particularly, the supplementary dust collecting bag 23 is located at a position surrounded by the wall surface of the inner body 10, the exhaust pipe 14, and the exhaust chamber 15, and can be stably held even when the number of the supplementary dust collecting bags 23 is different.

FIG. 5 is a view showing the inside of the lid case 4 side, except for the portion shown by the alternate long and short dash line with which the inner main body 10 abuts,
Also, a floor suction port 24, a power cord 25, and a pocket portion 26 for accommodating other small parts are provided at a position where they do not interfere with the applied parts housed in the main body case 3 side.

On the opening side surface of the lid case 4, a cutout portion 27 for holding the exhaust chamber 15 and a hose 16 as shown in FIG.
A lid body 28 that can be opened and closed is provided so that it can be taken out. In the portion of the main body case 3 facing the lid body 28,
A notch 29 is provided as shown in FIG. FIG. 6 is an external view seen from the exhaust chamber 15 side, and FIG. 7 is an external view seen from the lid body 28 side. FIG. 8 is a longitudinal sectional view, in which the lid body 28 is supported by a hinge 30 provided on the lid case 4 and is bistable between the engaging projection 31 and the locking projection 31 as indicated by a dashed line arrow. Can be opened and closed. Since it can be opened / closed in this way, as shown in FIG. 1, 44 is formed integrally with the dust collecting part 13 in the switch case, and operates according to the negative pressure in the power switch 45 and the dust collecting part 13 to remove the dust collecting bag 12. Indicator for clogged condition 46
Is built in.

Since the switch case 44 is also provided so as to face the lid body 28, when the lid body 28 is opened, the power switch 45 and the indicator 46 are exposed to the outside so that they can be operated and visually checked.

FIG. 9 shows a state in which the swivel joint 17 is rotated and the hose 16 is taken out of the main body case. At the portion where the power cord 32 is exposed to the outside of the body case 3, as shown in FIG. 6, a recess 33 of a parabolic shape is provided, and the power cord 32 is fitted into the recess 33 and temporarily fixed to the body case 3, The power cord 32 is not caught and damaged when the lid case 4 is split and opened / closed at the joint surface.

Supported by.

36 is a dust collecting part lid that opens and closes the dust collecting part 13 in a detachable manner. 37 is a leg portion provided on the hinge 2 side of the main body case 3 and the lid case 4.

FIG. 11 is a cross-sectional view including the exhaust pipe 14 part, in which a shoulder band 38 is provided in the space between the main body case 3 and the exhaust pipe.
It is suitable for accommodating small flexible parts that are bent.

FIG. 12 is a cross-sectional view showing a state where the main body case 3 and the lid case 4 are opened, and the hinge 2 and the leg portion 37 can open about 180 °. Each application part housed inside in this state has a front opening, so that the housed position can be identified at a glance. Also, because it is stably placed on a flat surface such as the floor, it is easy to take out and store.

As shown in the figure, the hose 16 and the swivel joint 17 are arranged near the dividing surface of the main body case 3 and the lid case 4, that is, near the center surface, but they are deformed along the main body case 3 side due to their own weight, so they are stored. At this time, if the hose 16 is bent and stored along the inner wall shape, even if the hose 16 has a repulsive force and a force to expand, it is possible to stably store and retain the shape of the lid case 4. Even when it is closed, it doesn't get in the way by slipping in.

Further, since the dust collecting cover 36 is in a state of protruding from the opening surface of the main body case 3, it is easy to visually confirm and the workability of opening / closing the dust collecting part 13 and attaching / removing the dust collecting bag 12 is improved. .

With the above-described structure, the components housed as shown in FIG. 4 are the components housed in the inner surface of the main body case 3 and the lid case 4.
Since the hose 16 is arranged so as to be sandwiched between the hose 16 and the parts to be housed inside, the hose 16 will be exposed even if the carrying case 1 is tilted in each direction or a shock is applied during carrying. There is nothing to do. On the contrary, the applied parts are fitted and temporarily fixed in the recesses of the main body case, but by holding the hose 16 as described above, the parts are also pressed against the recesses of the main body case 3 and the lid case 4. If an external force is applied by a shock, it will not come off.

However, since a heavy part such as the floor suction port 24 is apt to come off when an impact is applied, if it is held between the recessed part 39 provided in the inner body 10 as shown in FIG. Can be held at In addition, a large part such as the floor suction port 24 positively increases the volume of a portion that does not interfere even if the recess 39 is provided in the inner body, like the small diameter portion of the electric blower 11 in the inner body 10 as described above. By utilizing it, the volume of the storage case 1 can be minimized.

The inner body 10 is also fitted with the floor suction port 24 as described above, and is fitted with the inner walls of the body case 3 and the lid case 4, and the inner body 10 and the lid case 4 on the hinge 2 side are It is in contact with the side surface and is dispersed and supported as a whole even when an impact is applied in each direction.

On the other hand, as shown in FIG. 4, the application mouth 22 for the gap has an internal body with a substantially circular cross section, which incorporates the electric blower 11.
The undercut portion between the 10 and the body case 4 is provided with a recess for storage at a recessed position so that the space volume can be effectively used and at the same time the inner body 10 can be pressed down from above to make it strong. It is especially effective when accommodating and holding small and heavy parts.

By configuring as described above, it is possible to store the internal body 10 and various applied parts in spite of its small size, and by combining the hose 16 having the swivel joint 17 and the lid body 28,
With the main body case 3 and the lid case 4 closed, the hose 16 can be taken out of the storage case 1 in a state of being assembled in a so-called bag shape for cleaning work. From this, the usage patterns are as follows: the stationary type with the legs 37 grounded as shown in FIG. 13, the floor transfer type with the caster 19 grounded as shown in FIG. 14, and the hook part of the shoulder band 38 as shown in FIG. Hook 41 with 40 on the storage case 1 side
Engage with the shoulder type, and as shown in Fig. 16, handle 7
The hand 43 can be carried between the hook 42 on the side and the hook (not shown) provided on the side of the leg portion 37 to be carried on the back. Also in each form, the floor surface or each surface of the storage case 1 in contact with the human body can be configured without any protruding projections and irregularities, and the outlet of the hose 16 and the direction of exhaust from the exhaust chamber 15 are Even in each usage mode, the layout is suitable so as not to disturb the human body or cause discomfort to the human body.

Of course, as shown in FIG. 1, it is also possible to pull out the hose 16 with the main body case 3 and the lid case 4 open and use it as it is.
