Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to household and commercial electric vacuum cleaners, and more particularly to an electric vacuum cleaner having a holder attached to an extension pipe and having excellent operability.

[0002]

2. Description of the Related Art FIG. 7 is a schematic view showing a general form of a conventional vacuum cleaner. In the figure, 1 is a floor brush, 2 is an extension pipe, 5 is a cleaner body incorporating an electric blower, and 7
Is a hose, 8 is a pipe at hand, 9 is a rear wheel attached to the cleaner body 5, and 10 is a caster attached to the front lower surface of the cleaner body 5. FIG. 8 shows a state in which the extension pipe 2 is attached to the conventional floor brush 1, and 12 is a wheel attached to the lower surface of the floor brush 1 for smoothing the movement of the floor brush 1.

Next, the operation will be described. Vacuum cleaner body 5
Pull out the power cord provided in and plug the plug into an outlet. Then, when the power switch provided on the hand pipe 8 is turned on, the cleaner body 5 starts operating, and the floor brush 1 is moved back and forth on the tatami mat, floor, carpet, etc. to suck dust and the like for cleaning. .

[0004]

Generally, when cleaning using an electric vacuum cleaner, the user holds the extension pipe 2 and the hand pipe 8 in his hand. However, in recent years, since a motor or the like is used for the floor brush 1 in order to improve the cleaning performance, wire rods or the like for the motor are attached to the extension pipe 2 and the hose 7, and become heavy. Therefore, when used for a long period of time, there is a problem in that the convenience of operation is lost due to this weight. In addition, when the use is temporarily stopped during use, the pipe 8, the extension pipe 2, the hose 7 and the like cannot be stood upright and must be placed directly on the floor, tatami mat, or carpet. Each time it is reused, it is necessary to bend over and take the hand pipe 8 and the extension pipe 2, etc., which is troublesome in use.

The present invention has been made to solve the above problems, and an object thereof is to solve the problem of operability caused by the weight during use and to obtain a convenient electric vacuum cleaner. It was done.

[0006]

In the vacuum cleaner according to the present invention, the holder is attached to the extension pipe so that the holder bears the weight of the extension pipe or the wire for the motor attached to the hose during cleaning. By moving the floor brush back and forth on the tatami mat, floor, carpet, etc. by the wheels provided in the holder, the operability of the floor brush is improved.
Further, by inserting and holding the wheels provided in the holder in the holder holding portion provided in the main body of the cleaner, the usability at the time of reuse is improved.

[0007]

When the electric vacuum cleaner is used, the extension pipe is held at a predetermined angle by the holder and the floor brush is moved to clean the floor surface or the like. At this time, the wheels provided on the holder assist the movement of the floor brush back and forth. When cleaning is temporarily stopped, insert the wheel of the holder into the holder holding part of the vacuum cleaner body and hold the extension pipe, hand pipe, hose, etc. in almost the state of use. When cleaning the vacuum cleaner and retracting the vacuum cleaner, rotate the holder and clamp it on the extension pipe.

[0008]

1 is a perspective view of an embodiment of the present invention. In addition,
The same parts as those of the conventional example shown in FIGS. 7 and 8 are designated by the same reference numerals, and the description thereof will be omitted. In FIG. 1, 3 is a holder attached to the extension pipe 2. As shown in FIGS. 5 and 6, this holder is provided with an arc-shaped main body 31 corresponding to the outer shape of the extension pipe 2, a holding portion 32 provided at the upper end portion and through which the extension pipe 2 is inserted, and a lower end portion. It comprises a wheel mounting portion 35 to which the wheel 4 is mounted. In addition, 6 is a concave holder holding portion provided in the cleaner body 5.

Next, the operation of the present invention configured as described above will be described. When storing the vacuum cleaner, the holder 3 is shown in FIG.
As shown in FIGS. 4 and 6, since the main body 31 holds the extension pipe 2 by sandwiching it, first, hold the wheel 4 in the hand and move the holder 3 around the holding portion 32 in the right direction of FIG. Rotate. As a result, the holder 3 becomes free with respect to the extension pipe 2. In this state, the holder 3 is moved to a desired position along the extension pipe 2 as indicated by an arrow 11 in FIG. 2, and then the lower end is further rotated rightward in FIG. As a result, the edges 33 and 34 (see FIG. 6) of the holding portion 31 are locked to the extension pipe 2, and the holder 3 is held at that position.

Then, the user holds the extension pipe 2 or the hand pipe 8 and the like to turn on the switch, and moves the floor brush 1 back and forth to clean the floor surface and the like.
At this time, the weight of the extension pipe 2, the hand pipe 8, the hose 7, etc. is borne by the holder 3 and reduced, and the wheel 4 attached to the tip of the holder 3 assists the forward and backward movement of the floor brush 1, The operability can be improved. In this case, the holder 3 appropriately adjusts its position so that the user can move the floor brush 1 in the most comfortable state.

In the conventional vacuum cleaner, when the use is temporarily stopped, the floor brush 1, the extension pipe 2, the hand pipe 8 and the like are usually placed on the floor. However, in the present invention,
As shown in FIG. 1, by inserting the wheel 4 provided at the tip of the holder 3 into the holder holding portion 6 provided in the cleaner body, the extension pipe 2 and the hand pipe 8 are held in a state close to that during use. be able to. Therefore, the user does not have to bend over to get the extension pipe 2 and the hand pipe 8 placed on the floor, and the burden on the body can be reduced. When the cleaning is finished, the holder 3 is pushed toward the extension pipe 2 in FIG.
The extension pipe 2 can be housed along the side surface of the extension pipe 2 by being pivoted around, and the extension pipe 2 being sandwiched by the edge portions 33 and 34 of the holding portion. Further, in this state, it is possible to clean a narrow place like a conventional electric vacuum cleaner.

[0012]

As described above, according to the present invention, since the holder having the wheels is attached to the extension pipe of the electric vacuum cleaner, the operability during cleaning can be improved. In addition, by inserting the wheel of the holder into the holder holding portion provided in the cleaner body, the user does not have to bend his or her waist during reuse, so the burden on the body can be reduced.
