DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A case where an embodiment of the vacuum cleaner of the present invention is applied to a canister type vacuum cleaner will be described below with reference to FIGS.

In the vacuum cleaner of the present invention, an electric blower 14 and the like are disposed in a main body 13 formed by a main body lower part 11 and a main body upper part 12, and a dust collecting chamber or the like for storing a dust collecting bag is formed. A case cover 16 having an opening / closing knob 15 for allowing a dust collection bag to be attached to the dust collection chamber is attached to the upper body 12 so as to be openable and closable. A button 18 is provided, and a main body pipe 22 of a connection hose 21 is connected to a suction port 19 of the main body 13 by a clamp button 20 so as to be capable of coming and going with the clamp button 20.
A free wheel 24 and a pair of wheels 25 for traveling are provided on the bottom surface 23 of the lower body 11 of the vehicle, a right handle 26a is provided on a right side surface 11a of the lower body 11, and a left handle 26b is provided on a left side surface 11b.
Is provided.

In the above construction, the right handle 26a and the left handle 26b have a handle body 27 formed of a hard material such as plastic as shown in FIG. 3, and a soft material such as rubber serves as a bumper on the outside. The buffer portion 28 is formed.

The outer perimeter 29 of the front surfaces of the handles 26a, 26b
A curved surface (R surface) R 1 is (large R, large radius) curved R 2 is larger than the curved front peripheral corner of the suction portion 19 side of the case cover 16 and / or body under 11, that is R1> formed on the relationship R2, it is intended to set the curved surface R 1 of the front outer periphery 29 at an obtuse angle.

The height a of the main body 13 (the sum of the height of the main body 13 and the height of the wheels provided on the main body 13 as shown in FIG. 1) a is set smaller than the width b of the main body 13 ( a <b).

Next, a description will be given of a state in which the vacuum cleaner constructed as described above is lifted by the handle.

First, as shown in FIG.
When the main body 13 is lifted by holding the main body 13a, the upper surface of the main body 13 (the surface on which the case cover 16 is provided) can be held inward, and the main body 13 can be held by the right hand and the left handle 26b as shown in FIG. When lifted, the upper surface of the main body 13 can be held inward.

Therefore, in any case, even if the main body 13 is lifted with the right or left hand, the upper surface of the main body 13 can always be held inward, and the wheels of the main body 13 or the bottom surface of the main body 13 can be held. Does not come into contact with the human body (clothes), and the clothes can be reliably prevented from being stained.

The distance (dimension) between the right or left hand holding the handles 26a and 26b and the human body is half (a / 2) of the height of the main body 13, and the height dimensions a to It becomes smaller than half (b / 2) of the width dimension of the main body 13 and can be easily held.

When the electric vacuum cleaner is traveling forward, the case cover 16 of the main body 13 and / or the suction portion 19 of the lower body 11 are connected to the case cover 16 by the curved surface R2 of the front outer periphery 29 of the handles 26a and 26b. / Or curved surface R of the front outer peripheral corner on the suction portion 19 side of lower body 11
Since it is formed on a curved surface larger than 1, the contact is soft even for contact with obstacles, preventing hindrance of running and smooth running, and also preventing damage to the main body 13. And damage can be reliably prevented.

[0016]

Since the vacuum cleaner of the present invention has the above-described structure, the wheel of the main body or the bottom surface of the main body is worn on the human body (clothes).
Clothes) so that it does not come into contact with
The hand can be selected and the body can be lifted without difficulty ,
It can reliably prevent clothes from being stained, can be easily carried with a handle, can run smoothly, and even if it hits obstacles during running It is possible to reliably prevent breakage without damage.
