DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner having a rotatable handle for carrying the vacuum cleaner body.

[0002]

2. Description of the Related Art Conventionally, this kind of vacuum cleaner is disclosed in
The configuration shown in, for example, -128736 was common.

Hereinafter, description will be given with reference to FIGS. Reference numeral 1 denotes a main body below which is formed with a dust collecting chamber (not shown) having an upper opening at the front side and a dust suction motor (not shown) and the like at the rear. A roller 2 for movement is attached to the rear side surface of the lower part 1 of the main body, and a caster roller 3 is attached to the bottom surface of the front part.

The rear opening of the lower body 1 is covered by an upper body 4 integrally connected to the lower body 1 by screwing or the like. Reference numeral 5 denotes a lid for covering the upper opening of the dust collection chamber at the front of the lower part 1 of the main body, which is rotatably attached to the upper part 4 of the main body. Reference numeral 6 denotes a handle which has a rotation center formed by rotation shafts 7 and 7 'on the main body 4 and is housed in a groove (reception surface) 8 provided in the lid 5 and is rotatable. It is used to carry the main body of the vacuum cleaner (hereinafter referred to as the main body).

[0005]

In the above structure,
Since the groove 8 for accommodating the handle portion 6 in the lid 5 is formed in a substantially U-shape, even if dust accumulates in the groove 8, it cannot be easily removed. In addition, the height when the handle portion 6 is set up is only 4 to 5 cm higher than the upper surface of the main body, and when the user carries the main body, the hand does not reach unless the user bends down to hold the handle portion 6,
This was annoying for elderly people who had difficulty bending their hips. Further, a storage space is required to store the handle portion 6 on the main body 4 or the lid 5, and the height of the main body may be increased to secure the storage space.
It was necessary to reduce the capacity of the dust collection chamber.

The present invention solves such a problem. The conventional handle portion 6 is enlarged without increasing the outer dimensions of the main body, thereby eliminating the inconvenience of use, and the receiving surface of the handle portion 6 is improved. It is an object of the present invention to provide a vacuum cleaner having a configuration that makes it difficult for garbage to accumulate and that can be easily removed even if garbage accumulates.

[0007]

Means for Solving the Problems The technical means of the present invention for solving the above problems is to accommodate a dust collecting chamber, a motor and the like.
In the main body of the vacuum cleaner having a storage chamber formed therein, the center of rotation of both sides of the main body of the vacuum cleaner is provided through an arm.
The handle portion so as to cover the side and rear surfaces of the vacuum cleaner main body rotatably formed, the receiving surface that opens outward and down stage body side to the arm downward is formed, the receiving surface is electrically It is formed so as to descend from the rear of the cleaner body toward the center of rotation, and the cross-sectional shape of the handle is
The arm is configured such that the surface is lowered outwardly.
Outside the receiving surface where dust collected at the center of rotation due to the rotation of
It is something that was scraped out .

[0008]

The operation of the above arrangement is as follows.

The handle is formed so as to cover the side surface and the rear surface of the vacuum cleaner main body from the center of rotation via the arm, so that the handle can be turned upside down when the handle is turned upside down. The position of the handle portion is raised, so that the user does not need to bend down when carrying the vacuum cleaner main body, and the user can carry the vacuum cleaner main body.

Further, dust accumulated on the receiving surface of the arm of the handle portion formed on the main body is gathered at the center of rotation of the handle portion along the inclination of the receiving surface due to vibration due to movement during use, and the side faces are outward. By rotating a handle (arm) having a cross-sectional shape that descends toward the outside, the collected dust is scraped out of the receiving portion and is automatically cleaned.

Further, the handle portion is formed on a part of the outer surface of the vacuum cleaner so that the design can be improved and the height of the vacuum cleaner body can be reduced.

[0012]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1 to FIG. 4, reference numeral 21 denotes a lower part of a main body in which a dust collecting chamber (not shown) having an upper opening is formed at the front side, and a dust suction motor (shown by a broken line) 22 and the like are installed at the rear side. The roller 2 for movement is provided on the rear side surface of the lower part 21 of the main body.
3. A caster roller 24 is attached to the front bottom surface.

The upper opening of the motor 22 is covered by an upper body 25 integrally connected to the lower body 21 by screwing or the like. Reference numeral 26 denotes a front cover which has an air inlet for connecting a hose and is integrally fixed to the lower part 21 of the body by screwing or the like. Reference numeral 27 denotes a lid that covers the upper opening of the dust collection chamber, and is rotatably mounted on the main body 25. A substantially U-shaped handle portion 29 having a rotating shaft 28 formed near the center of gravity of the main body is formed above the upper side of the main body 25 to form a part of the outer shell of the main body. As shown in FIG. 2, the handle 29 is formed so that a side surface thereof is lowered outward, and an arm 29 for connecting the rotating shaft 28 to the handle 29 serving as a grip portion. 'have.
A receiving surface 25 ′ having an outward opening is formed on the upper body 25 below the arm 29 ′, and the receiving surface 25 ′ is configured so as to descend from the rear of the main body toward the rotating shaft 28 of the handle 29. I have.

The operation of the above configuration is as follows. A large handle portion 29 can be formed by forming a rotation shaft 28, which is the center of rotation of the handle portion 29, near the center of gravity of the main body, and by forming the outer periphery of the main body. Also, the handle 2 formed on the upper body 25
9, the receiving surface 25 'is opened outwardly and lowered from the rear of the main body toward the rotation shaft 28, so that the receiving surface 25' is moved by vibration during cleaning or the like.
The accumulated garbage first falls outside the receiving surface 25 ',
Or, they gather near the rotation shaft 28 of the handle 29 along the inclination of the receiving surface 25 '. As shown in FIG. 3, the dust collected near the rotation shaft 28 is received by the receiving surface 2 by the rotation of the arm 29 ′ having a cross section whose side surface is lowered outward.
It is swept out of 5 '.

[0016]

As described above, the present invention has the following significant effects.

A large handle portion is formed without increasing the external dimensions of the main body by forming a rotation axis, which is the center of rotation of the handle portion, near the center of gravity of the main body and forming the outer periphery of the main body. It is easy to grasp and improves usability.

Further, the receiving surface of the handle formed on the main body is formed so as to open outward and descend from the rear of the main body toward the center of rotation. Debris that has accumulated on the receiving surface first falls outside the receiving surface, or even if it does not fall, it collects near the rotation axis of the handle part along the inclination of the receiving surface, and the side surface is lowered outward The object is swept out of the receiving surface by the rotation of the arm having the shape, and automatically removes dust accumulated on the receiving surface.

Further, the handle portion is formed as a part of the outer shell of the main body, so that the design can be improved.

As described above, the present invention is practically used.
A very useful effect is obtained.
