DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner body having a built-in electric blower, a suction port rotatably connected to a lower end of the vacuum cleaner body, and the vacuum cleaner. The present invention relates to a so-called upright type vacuum cleaner having a handle connected to an upper end side of a main body.

[0002]

2. Description of the Related Art Conventionally, a vacuum cleaner having a built-in electric blower is miniaturized, and a suction port is rotatably connected to a lower end of the vacuum cleaner. A so-called upright type in which a long hose is eliminated by connecting an arm-shaped handle to the side is known.

[0003] In such an upright type vacuum cleaner, the handle is grasped while the suction port is grounded on a surface to be cleaned such as a floor, and the main body of the vacuum cleaner is moved to a predetermined position. By inclining at an angle, the suction port moves over the surface to be cleaned integrally with the main body of the cleaner by pushing and pulling back the handle, so that dust and the like on the surface to be cleaned can be sucked.

[0004]

By the way, in the vacuum cleaner constructed as described above, since the suction opening, the cleaner body and the handle are integrated with each other, the cleaning operation is particularly difficult during the cleaning operation. The load of a relatively heavy cleaner body such as an electric blower is transmitted to a cleaning worker via a handle.

[0005] Therefore, in an environment in which cleaning work is performed for a long time, use of a relatively elderly person, or the entire vacuum cleaner is once lifted in order to get on a sill or the like, the degree of fatigue associated with the weight of the cleaner body is increased. There has been a problem that the burden on the cleaning operator, such as cleaning and operability, is large.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide an electric vacuum cleaner capable of reducing a burden on a cleaning operator due to the weight of the main body of the vacuum cleaner.

[0007]

According to a first aspect of the present invention, there is provided a cleaner body having a built-in electric blower and a rotatably connected lower end of the cleaner body. An upright type vacuum cleaner having a suction port body and a handle connected to an upper end side of the cleaner body, wherein one end is connected to the cleaner body and the other end has a predetermined angle. The gist of the present invention is to provide an arm member having wheels for assisting movement of the cleaner main body while supporting the main body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a vacuum cleaner according to the present invention will be described with reference to the drawings.

In FIG. 3, a vacuum cleaner 1 includes a cleaner body 2 having a built-in electric blower (not shown) and a cleaner body 2.
A suction port 3 rotatably connected to the lower end of the vacuum cleaner, a handle 4 connected to the upper end of the cleaner body 2, and an arm member 5 rotatably mounted on the cleaner body 2. ing.

The arm member 5 includes a pair of arms 6 rotatably mounted at one end on the left and right sides of the cleaner body 2, a wheel 7 rotatably mounted at the other end of the arm 6, and a pair of arms. And a connecting member 8 connecting the connecting members 6 to each other.

As shown in FIG. 1A, the arm member 5 is in a retracted state along the cleaner main body 2 when the cleaner main body 2 is not used when the cleaner main body 2 stands upright on the floor surface Y.
As shown in FIG. 1B, during normal use in which the cleaner main body 2 is at a predetermined angle with respect to the floor surface Y, a normal use state substantially perpendicular to the floor surface Y, and as shown in FIG. At the time of special use in which the cleaner main body 2 is lying on the floor Y (for example, when cleaning a low cleaning space such as under a table or a bed).
Can be changed to a special use state in which the arm 6 lies on the floor Y in the direction in which the wheels 7 separate from the cleaner body 2.

At this time, as shown in FIG.
A plurality of engaging projections 2a, 2 that maintain the storage position of the arm member 5 and the normal use position or the special use position by engaging at least one side surface of the arm 6 near one end thereof.
b, 2c are provided.

The engaging projections 2a, 2b, 2c also serve as stoppers by, for example, setting the projecting height of the engaging projections 2c to such a height that the arm 6 cannot be climbed over. By setting the height of 2b higher than the height of the engagement protrusion 2a and lower than the height of the engagement protrusion 2c, it is possible to set such that the arm member 6 maintains the normal use position during the cleaning operation. The engagement projections 2a, 2
By increasing the number of b and 2c, the versatility of the use angle of the arm member 5, that is, the use environment of the vacuum cleaner 1 can be improved.

In the above configuration, the suction port 3 is connected to the floor Y
The handle 4 is grasped while being grounded, and the cleaner body 2 is held.
Is tilted at a predetermined angle shown in FIG. 1 (B), and the suction port 3 moves on the floor Y integrally with the cleaner body 2 by pushing and pulling back of the handle 4 so that the suction port 3 moves on the floor Y. It can inhale dust and the like.

At this time, since the center of gravity G of the cleaner body 2 is located between the suction opening 3 and the pivot of the arm 6,
The load of the cleaner main body 2 is distributed to the suction port body 2 and the arm member 5 and hardly affects the handle 4, and the fatigue caused by the load of the cleaner main body 2 when used for a long time or for elderly people. The degree is reduced.

In addition, when the vehicle goes over a threshold or the like during normal use, the handle 4 is lowered to the floor surface Y side, so that the vacuum cleaner 1 is rotated about the support portion of the arm 6 as a fulcrum, and only the wheels 7 are on the floor surface. Since the suction port body 3 is separated from the floor surface Y by touching the ground, the sill and the like can be easily overcome, and not only the operability is improved, but also the degree of fatigue caused by the overload of the cleaner body 2 is reduced. Is done.

Further, by setting the height of the projections of the engagement projections 2a, 2b, and 2c, or by setting the engagement projections 2a, 2b, and 2c to be able to protrude and retract from the side surface of the cleaner body 2, a return spring and the like are set. It is possible to automatically or semi-automatically change the arm member 5 from the normal use position to the storage position and from the special use position to the normal use position in conjunction with the change in the use angle of the cleaner body 2.

[0018]

As described above, in the electric vacuum cleaner according to the first aspect, cleaning is performed with one end connected to the cleaner main body and the other end supporting the cleaner main body at a predetermined angle. The provision of the arm member having wheels for assisting the movement of the cleaner main body can reduce the burden on the cleaning operator related to the weight of the cleaner main body.

Further, in the vacuum cleaner according to the second aspect, the arm member is provided on the cleaner body so as to be switchable between a storage position and a use position, so that the vacuum cleaner is not used. When the arm member is not used, the arm member can be stored so as not to be in the way.

Further, in the vacuum cleaner according to the third aspect, the arm member is provided on the cleaner body so as to be switchable to a plurality of use positions, so that it can be adjusted to various use states. Therefore, the usability can be improved.
