Hereinafter, one embodiment of the vacuum cleaner of the present invention will be described with reference to the drawings. The vacuum cleaner main body 1 consists of an electric blower 2, a cord reel 4 wrapped with a power coat 3, and a dust collection section 6 equipped with a paper bag filter 5, and the dust collection section 6 is equipped with a collection a lid 7. . The vacuum cleaner main body 1 consists of a hemispherical upper case 1a and a lower case 1b. The vacuum cleaner body 1 has casters 8 extending from the vacuum cleaner body 1 and mounted on all sides, and a wheel base 10 that can rotate with respect to the vacuum cleaner body 1 via a rotation shaft 9.
It is equipped with

To further explain each part, the electric blower 2 includes a vibration-proof rubber 1
1.12, it is held in the vacuum cleaner body 1 so as to be gripped from both sides. A sound absorbing cover 13 is placed around the electric blower 2.
, a sound insulating wall 14 is provided.

The sound insulating wall 14 is integrally formed with sound muffling tubes 1 and 5. The dust collecting section 6 includes a vibration-proof rubber 12 on the front side of the electric blower 2.
The inner case l6 is in contact with the inner case l6. A filter material is stretched inside the inner case 16, and
An after filter 17 formed in a box shape is attached.

The paper bag filter 5 can be set inside the after filter 17, and can be attached by attaching one side of the mouth paper part 5a of the paper bag filter 5 to the after filter 17 and the other side to the filter stand 35. . In addition, the filter stand 35 is provided with a recess 37 that can accommodate a deodorizing and aromatic agent 36, and these four parts have claws 38 to prevent the deodorizing and aromatic agent 36 from coming off, and a window for dispersing the deodorizing and aromatic agent. A section 39 is also provided. An airtight packing l8 is provided around the opening of the afterfilter 17. The airtight packing 18 is attached to the inner case 16
The opening end of the dust collecting part 6 comes into contact with the back M7a of the dust collecting lid 7.
It is constructed to maintain airtightness. The dust collection lid 7 also has a hose attachment port 2 to which a hose 19 can be detachably attached.
o, and is configured to be rotatable. To attach and detach the paper bag filter 5, release the clamp 21 and remove the dust collector M7.
It is done by opening and closing.

The top surface of the vacuum cleaner 1 is provided with a carrying handle 22 and a dust meter 23 that displays the amount of clogging of the filter. A plurality of axles 24 are attached to the bottom surface of the cleaner body 1, and abut against the inner surface of the wheel stand 10 to make the rotation of the cleaner body 1 and the transport stand 10 smooth.

Furthermore, a tire portion 24a is also provided on the outer periphery of the wheel 24 to reduce running noise.

The wheel stand 10 is connected to the lower case 1b of the remover main body 1 and the rotating shaft 9.
It is fixed with a screw from the bottom through a washer,
It can be rotated around the rotation axis 9, but when it rotates 360 degrees, it hits the stopper 25 and the rotation is inhibited. In other words, it can be rotated 360 degrees to the right and 360 degrees to the left. Further, the wheel platform 10 is configured to have a substantially circular shape when viewed from above. The casters 8 are provided so as to protrude from the outer shape of the cleaner body 1.

A caster force par 26 is provided on the axle stand 1o so as to cover the caster 8. The outer periphery of the caster force bar 26 and the wheel base 10 is provided with a
A bumper 27 is provided. This bumper 27 is
It constitutes the outermost shape of the vacuum cleaner body 1.

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

In the above configuration, when using the vacuum cleaner, the hose 19, extension pipe 30,
Connect the suction port 31, 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 tip of the hose 19 is turned on, the electric blower 2 is operated, and the air flow containing a large amount of dust from the suction port 31 passes through the extension pipe 30 and the hose 19 due to the suction force. 6, dust and clean air are filtered out by the paper bag filter 5, and only the clean air flow passes through the electric blower 2 and the muffling tube 15, and is discharged from the exhaust port 28 at the rear. When the room is cleaned in this state, even if the axle stand 10, caster cover, and -26 part hit an obstacle 33 such as furniture placed in the room, the bumper 27 protects the furniture and prevents damage to the furniture.

In addition, in this vacuum cleaner, the main body 1 of the vacuum cleaner can be rotated on the wheel stand 10, making it easy to change the direction of the hose 19 in a small room. Since the vacuum cleaner is rotated by the wheels 24 between the wheel base 10 and the cleaner main body 1, it is possible to lightly operate the vacuum cleaner on the surface to be cleaned without being affected by the rotation. Conversely, even if the caster force bar 26 or the like gets caught on the legs of a table or the like as shown in FIG. can be cleared, and the vacuum cleaner can be moved smoothly even in area R where there is a lot of furniture. Furthermore, since the cleaner main body 1 cannot rotate freely with respect to the wheel base 10 and the rotation angle is limited, the vacuum cleaner can be routed without the power cord 3 wrapping around the wheel base 10. Furthermore, in the vacuum cleaner of this embodiment, the casters 8 are arranged to protrude outward from the vacuum cleaner body 1, and the bumper 27 of the vacuum cleaner body 1 is configured to have the largest external dimension, so that it does not come into contact with obstacles. , Vacuum cleaner body ill to which hose l9 is attached
Even if it is fixed, the lower wheel stand 10 can rotate to avoid it. Furthermore, the roots of some of the protruding casters have a smooth shape and are connected to the outer periphery of the wheel platform 10, so that even if they hit an obstacle, it can be slid and avoided, and the caster 8~ It has four directions, so it is designed to allow for smooth changes in direction and over thresholds. Further, according to this embodiment, since the electric blower 2 and the cord reel 4 are arranged at a low position, a low center of gravity gutter structure can be used to prevent the vacuum cleaner from falling over, which is advantageous. Furthermore, electric blower 2
Since the part is covered by the wheel stand 10 part from the outside, the noise generated by the electric blower 2 is also reduced because the lower case 1b and the case of the axle stand 10 form a double case structure.
The sound insulation effect increases and noise can be further reduced. Since the shape of the cleaner main body 1 and the axle base 10 when viewed from above is approximately a perfect circle, rotation can be performed with the minimum radius even when changing direction in a narrow area. Further, in this embodiment, the exhaust port 28 is provided at the rear of the cleaner body 1, but it may also be a distributed exhaust outlet that discharges the air from the entire circumference of the sliding portion 34 of the cleaner body 1 and the wheel base 10. At this time, by configuring the opening width of the sliding part 34 to be smaller than the diameter of the power cord, it is possible to prevent the cord from getting caught in the sliding part 34 when the cleaner main body rotates.

As yet another embodiment, when the flat part 1c is formed on the top surface of the vacuum cleaner main body l and used as a chair, the rotating wheels 2
4, so even if the floor is on a tatami mat or carpet, it can be used as a rotating chair since it does not have to generate undue force with these surfaces when rotating. It is also possible.

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

- Since the electric blower 2 and cord reel 4 are arranged at a low position, a structure with a low center of gravity can be adopted to prevent the vacuum cleaner from falling over, which is advantageous.

■ Since the electric blower 2 part is covered by the wheel stand 10 part from the outside, the noise generated by the electric blower 2 becomes a double case structure with the lower case 1b and the case of the wheel stand 10, increasing the sound insulation effect. As a result, even lower noise can be achieved.

■ Since low-speed exhaust is possible from around the entire circumference of the vacuum cleaner body, the exhaust flow discharged from the vacuum cleaner body does not kick up dust on the surface to be cleaned.

- Since the sweeper main body 1 and the wheel platform 10 have a nearly perfect circular shape when viewed from above, rotation can be performed with the minimum radius even when changing direction in a narrow area.

■ A vacuum cleaner body with a built-in dust collector and electric blower that houses a filter, a wheel stand on which the vacuum cleaner body is rotatably placed, and this wheel stand is moved over the surface to be cleaned while rotating. In the vacuum cleaner, the moving means is provided at the lower part of the wheel base and protrudes outward from the vacuum cleaner body, so that it is possible to check the condition of the surface to be cleaned and the furniture, etc. The vacuum cleaner itself can run stably without getting involved with obstacles.

■ The rotation range of the vacuum cleaner body 1 on the wheel stand 10 is 360 degrees.
Even if the power cord becomes entangled with the main unit due to rotation, if the main unit is rotated with excessive force,
There is a stopper that prevents the power cord from turning any further, which is good for safety as no excessive force is applied to the power cord.

〔Effect of the invention〕

According to the present invention, the opening size G of the exhaust port (rotating and sliding part) provided around the entire circumference is configured to be smaller than the outer diameter D of the power cord, so that the power cord can be caught in the rotating and sliding part of the vacuum cleaner body. No movement defects occur.
