The present invention also relates to a vacuum cleaner configured so that a power cord drawn from a code reel does not get caught in the rotating portion.

[Conventional technology]

Conventional vacuum cleaners are provided with a cleaner body and a wheel base for movement. On the wheel base, a cleaner body that can be rotated is disclosed in Japanese Utility Model Application Laid-Open No. 61-197937 and Japanese Utility Model Publication No. 43-29421. It was constituted as described in.

[Problems to be solved by the invention]

In the above prior art, regarding the power cord pulled out from the cleaner body side, no consideration is given to the entrapment of the power cord into both rotation gaps when the body side rotates on the wheel base, and the power cord is not considered. , The power cord will turn when the vacuum cleaner body rotates on the wheel base,
It was sandwiched between the rotation gaps between the two and hindered smooth rotation.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vacuum cleaner in which a power cord pulled out of the cleaner body is not pinched in a cleaner body rotating gap that rotates on a wheel base.

[Means for solving the problem]

In order to achieve the above object, the present invention is characterized in that a dust collecting part for storing a filter, a cord reel around which a power cord is wound, and a cleaner body including a built-in electric blower, and the cleaner body is rotated. A wheel base to be freely mounted, and a moving means for moving the wheel base on a surface to be cleaned while rotating the wheel base, and each of the cleaner body and the wheel base,
A rotation angle regulating member that regulates both rotation angles is provided, and a rotation gap between the cleaner body and the wheel base is configured to be smaller than the power cord diameter.

[Action]

According to the present invention, since the rotation angle regulating member for regulating the rotation angles of both the cleaner body and the wheel base is arranged, the cleaner body rotates on the wheel base and the power cord Even if wrapped around, the power cord is not subjected to excessive force, and the rotation gap between the cleaner body and the wheel base is smaller than the power cord diameter, so that the cleaner body can be used while the cleaner is in use. It is possible to prevent poor rotation caused by the cord being pinched in the rotation gap with the wheel base.

〔Example〕

Hereinafter, an embodiment of the vacuum cleaner of the present invention will be described with reference to the drawings. The cleaner body 1 includes an electric blower 2, a cord reel 4 around which a power cord 3 is wound, and a dust collecting section 6 in which a paper bag filter 5 is provided. The dust collecting section 6 includes a dust collecting lid 7. . The vacuum cleaner body 1 has a hemispherical upper case 1a and a lower case 1b.
Consists of The vacuum cleaner main body 1 has the caster 8 protruding from the vacuum cleaner main body 1 and mounted on all sides.
A wheel base 10 that can be rotated with respect to the rotating shaft 9 via a rotating shaft 9.

If each part is further explained, the electric blower 2
It is held by the cleaner body 1 so as to be clamped from both sides by 11 and 12. Around the electric blower 2, a sound absorbing cover 13 and a sound insulating wall 14 are provided. The sound insulating wall 14 is integrally formed with a sound deadening tube 15. The dust collecting section 6 includes an inner case 16 that is in contact with the vibration isolating rubber 12 on the front side of the electric blower 2. Inside the inner case 16, a box-shaped after filter 17 on which a filter material is stretched is mounted. The paper bag filter 5 can be set inside the after filter 17 and can be attached by attaching one side of the paper section 5a of the paper bag filter 5 to the after filter 17 and the other side to the filter base 35. . Deodorant and air freshener 36
Is provided with a claw 38 for deodorizing and preventing the fragrance 36 from coming off, and a window 39 for deodorizing and scattering the fragrance. An airtight packing 18 is provided around the opening of the afterfilter 17. The airtight packing 18 includes an opening end of the inner case 16 and a dust collecting cover 17.
The dust collecting part 6 is kept airtight by contacting the back cover 7a. Further, the dust collecting lid 7 is provided with a hose mounting port 20 to which the hose 19 can be detachably mounted, and is rotatable. Attaching and removing the paper bag filter 5 is a clamp
This is performed by releasing the dust cover 21 and opening and closing the dust collecting lid 7.

On the upper surface of the cleaner body 1, there are provided a carrying handle 22 and a dust meter 23 for displaying the amount of clogging of the filter. A plurality of wheels 24 are mounted on the bottom surface of the cleaner body 1 and are in contact with the inner surface of the wheel base 10 to form the cleaner body 1.
And the rotation of the wheel base 10 is made smooth. In addition, a tire portion 24a is provided on the outer periphery of the wheel 24 so as to reduce running noise.
Is also provided.

The wheel base 10 is fixed to the lower case 1b of the cleaner body 1 by screws from below the rotating shaft 9 via a washer, and can be rotated about the rotating shaft 9. 25 (rotation angle regulating member) and its rotation is suppressed. That is, it can rotate 360 degrees right and 360 degrees left. Further, the wheel base 10 is formed in a substantially circular shape when viewed from above. The caster 8 is provided so as to protrude from the outer shape of the cleaner body 1. A caster cover 26 is provided on the wheel base 10 so as to cover the caster 8. A bumper 27 for preventing damage to furniture and the like is provided on the outer periphery of the caster cover 26 and the wheel base 10. The bumper 27 forms the outermost shape of the cleaner body 1.

An exhaust port 28 and a power cord outlet 29 are provided on the rear side of the cleaner body 1.

In the above configuration, when a vacuum cleaner is used, the hose 19, the extension pipe 30, and the suction port 31 are connected to the hose mounting port 20 of the cleaner body 1.
And pull out the power cord 3 from the cord outlet 29 and insert it into an outlet (not shown). Next, when the operation switch 32 at the end of the hose 19 is turned on, the electric blower 2 is operated, and the air flow containing a large amount of dust passes from the suction port 31 through the extension pipe 30 and the hose 19 by the suction force, and the dust collection section Dust and clean air are separated by the paper bag filter 5 and the clean air flow passes through the electric blower 2 and the silencer 15 and is discharged from the rear exhaust port 28. When the room is cleaned in this state, even if the wheel base 10 or the caster cover 26 hits an obstacle 33 such as furniture placed in the room, the bumper
27 protects and prevents damage to furniture.

Further, in this vacuum cleaner, since the cleaner body 1 can rotate on the wheel base 10, it is easy to change the direction of the hose 19 in a small room or the like, and since the direction of the surface to be cleaned is changed by the caster 8, In addition, since the rotation is performed by the wheels 24 between the wheel base 10 and the cleaner body 1, the operation can be performed lightly on the surface to be cleaned without being affected by the rotation. Conversely, the caster cover 26 and the like are running around the cleaner body 1,
Even if it is hooked on the feet of a table or the like as shown in FIG. 4, the wheel base 10 rotates in reverse, so that obstacles can be cleared, and the cleaner can be moved smoothly even in a room with many furniture.

In addition, since the cleaner body 1 does not rotate unrestrictedly with respect to the wheel base 10 and limits the rotation angle, the power cord 3 is
The vacuum cleaner can be routed without winding around 10.
Further, in the vacuum cleaner of the present embodiment, the caster 8 is disposed so as to protrude to the outside of the vacuum cleaner main body 1, and the bumper 27 of the vacuum cleaner main body 1 is configured to have the maximum outer shape. Even if the side of the cleaner body 1 to which the hose 19 is attached is fixed, the lower wheel base 10 can be avoided while rotating. Furthermore, since the base of the overhanging caster part is tied to the outer periphery of the wheel base 10 in a smooth shape,
It is possible to avoid obstacles in a slipping manner, and to arrange the casters 8 in four directions, so that it is possible to smoothly change directions and cross over thresholds. Further, according to the present embodiment, since the electric blower 2 and the cord reel 4 are provided at a low position, a low center of gravity structure can be adopted even when the cleaner is overturned, which is advantageous for overturning. Furthermore, since the electric fan 2 is configured so that the wheel base 10 covers the outside, the noise generated by the electric fan 2 also has a double case structure by the lower case 1b and the case of the wheel base 10, so that the sound insulation effect is reduced. Increased noise can be further reduced. Since the shape of the vacuum cleaner body 1 and the wheel base 10 when viewed from above is substantially a perfect circle, rotation can be performed with a minimum radius even when turning in a narrow part. In this embodiment, an exhaust port is provided at the rear of the cleaner body 1.
Although 28 is provided, it may be a distributed exhaust port that exhausts from the entire circumference of the rotation gap between the cleaner body 1 and the wheel base 10. At this time, by configuring the opening width of the rotation gap to be smaller than the diameter of the power cord, it is possible to prevent the cord from being caught in the sliding portion 34 when the cleaner body rotates.

As still another embodiment, when the flat part 1c is formed on the upper surface of the cleaner main body 1, the rotating wheel 24 is used.
Is used, even if the floor surface is on a tatami mat or a tatami mat, it can be used as a rotating chair because it does not need to generate excessive force with these surfaces when rotating and rotate. Can also be.

According to the present embodiment, the following effects can be initialized.

Since the electric blower 2 and the cord reel 4 are arranged at a low position, a low center of gravity structure can be adopted even when the vacuum cleaner is overturned, which is advantageous for overturning.

Since the electric fan 2 is configured so that the wheel base 10 covers the outside, the noise generated by the electric fan 2 also has a double case structure by the lower case 1b and the case of the wheel base 10, so that the sound insulation effect is increased. Therefore, the noise can be further reduced.

Since exhaust at a low speed is possible from the entire circumference of the cleaner body, the exhaust flow discharged from the cleaner body does not cause dust or the like on the surface to be cleaned.

Since the shape of the vacuum cleaner body 1 and the wheel base 10 when viewed from above is substantially a perfect circle, rotation can be performed with a minimum radius even when turning in a narrow part.

A cleaner body including a dust collecting unit for accommodating a filter and an electric blower, a wheel base for rotatably mounting the cleaner body, and moving the wheel base on a surface to be cleaned while rotating. In a vacuum cleaner provided with a moving means, the moving means is provided at the lower part of the wheel stand and protruded outward from the main body of the cleaner. Stable running of the main body of the vacuum cleaner can be achieved without having to worry about objects.

Since the rotation range of the cleaner main body 1 on the wheel base 10 is within 360 degrees, even if the power cord is entangled with the main body by the rotation, if the main body is rotated with an excessive force, it is no more. Since there is a stopper that does not rotate, no excessive force is applied to the power cord, which is also good for safety.

〔The invention's effect〕

As described above, according to the present invention, each of the cleaner body and the wheel base is provided with the rotation angle regulating member that regulates the rotation angle of both, so that the cleaner body is arranged on the wheel base. Will rotate and the power cord will wrap around,
The power cord is not given excessive force and the rotation gap between the cleaner body and the wheel base is smaller than the diameter of the power cord. Rotational defects caused by the cord being pinched in the gap can be prevented.
