Field of the Invention The present invention relates to an electric vacuum cleaner, and more particularly, to an electric vacuum cleaner having a housing for an attachment in a main body of the vacuum cleaner, or a vacuum cleaner in which wheels can rotate smoothly. Things.

[0002]

2. Description of the Related Art FIG. 20 is a bottom view of a conventional vacuum cleaner having an attachment accommodating portion, FIG. 21 is an enlarged view of a main portion thereof, and FIG. 22 is a sectional view taken along line AA of FIG. In the drawing, 1 is a cleaner body, 2 is its lower case, 3a and 3b are wheels mounted on both sides of the rear part of the lower case 2, and 4 is a caster. Reference numeral 5 denotes a storage portion for an attachment which is opened to the rear surface below the rear end of the lower case 2, and an outlet 7 is provided between the bottom portion 6a and the top surface. Reference numeral 8 denotes a supporting portion protruding from the bottom 6a, 9 denotes a locking portion, 10 denotes a plug of a power cord, and 11 denotes an attachment.

[0003] Attachment 1 to storage section 5 as described above.
As shown in FIG. 23, in order to store the attachment 1, one end of the attachment 11 is held in a hand and pushed into the storage section 5 from the opening, supported by the support section 8, and locked by the locking section 9. When taking out the attachment 11 stored in the storage part 5, insert two fingers into the outlet 7 and attach the attachment 1.
You just have to bring it out and pull it out.

FIG. 24 is a side view of a conventional vacuum cleaner, and FIG.
5 is a longitudinal sectional view of the wheel portion, and FIG. 26 is BB of FIG.
It is sectional drawing. In the drawing, reference numeral 2 denotes a lower case, which has a cylindrical bearing 26 projecting from the rear of the side wall 2b, and a cylindrical rib 27a higher than the bearing 26 concentrically with the bearing 26 is provided on the outer periphery thereof. I have. Reference numeral 3a denotes a dish-shaped wheel, which is provided with a cylindrical axle 30 at the center thereof, the tip of which is divided into a plurality of portions, each of which is formed with a locking claw 31 (JP-A-4-236929). Gazette).

In order to mount the wheel 3a on the lower case 2, the axle 30 of the wheel 3a is mounted on the bearing 26 of the lower case 2.
And the locking claw 31 is locked to the side wall 2b. At this time, the tip of the cylindrical rib 27a is close to the inner wall of the wheel 3a, and when the wheel 3a rotates, it hits the inner wall of the wheel 3a to prevent blur.

FIG. 27 is a vertical sectional view of another conventional wheel portion of the vacuum cleaner, and FIG. 28 is a sectional view taken along the line CC of FIG. In this embodiment, the anti-shake cylindrical rib 33a is provided on the wheel side, and its tip is close to the side wall 2b of the cleaner body 2, and its operation is almost the same as that of the conventional example described with reference to FIG. Reference numeral 32 denotes a plurality of stoppers provided on the outer periphery of the axle 30 for positioning when the wheels 3a are mounted.

By the way, as shown in FIG. 20, the electric vacuum cleaner is usually provided with a power cord outlet 10a close to the wheel 3b (or 3a). The reel is automatically taken up on the provided reel. In this case, the power cord may enter between the cleaner main body 1 and the wheel 3b (or 3a) and become unwound. The occurrence of such an accident is shown in FIGS.
However, as shown in FIG. 29, the cylindrical ribs 27a and 33a are provided on the side wall 2b of the lower case 2 so as to be concentric with the bearing 26 and substantially one-fourth of the entire circumference from the lower part to the rear part. In some cases, a rib 40 for preventing entry of a cord is provided.

[0008]

In a vacuum cleaner having an attachment storage section 5 as shown in FIGS. 20 to 23, the outlet 7 of the attachment 11 has a small opening at the rear of the cleaner body 1. Attachment 1
1 is difficult to grasp when taking it out, and therefore, there is a problem that the attachment / detachability of the attachment 11 is poor.

Next, according to the structure for mounting the wheels to the cleaner body as shown in FIGS. 24 to 28, it is possible to prevent the wheels 3a and 3b from shaking, but the mounting on the bearing 26 is poor. In addition, dust and sand enter the cylindrical ribs 27a and 33a from between the tip of the cylindrical ribs 27a and 33a and the inner walls of the wheels 3a and 3b or the side walls of the lower case 2, and the bearings 26 and the axle 30 , And the wheels 3a, 3b often cannot rotate smoothly.

Further, as shown in FIG. 29, when a rib 40 for preventing entry of a cord is provided in the lower case 2, the rib 40 is provided only in a range of approximately one quarter of the entire circumference.
Although the mountability to the lower case 2 is good, not only the shake of the wheels 3a and 3b cannot be suppressed, but also dust and sand enter between the side wall 2b of the lower case 2 and the axles 3a and 3b,
This penetrates between the bearing 26 and the axle 30, and the wheels 3a,
3b may not be able to rotate.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object to provide a vacuum cleaner in which an attachment can be easily attached and detached.
