Abstract

PURPOSE:To effectively remove waste threads or hair from any carpet by forming an agitator internally provided in a floor nozzle main body of a rotor and a flexible protruding line band provided in the longitudinal direction of its peripheral face and using protrusions different in height formed on the front and the back of the protruding line band the protruding line band to a face to be cleaned. CONSTITUTION:When the an agitator 13 is rotated, a protruding line band 32 is displaced in the reverse direction of rotation at a part in contact with a face to be cleaned and moves along the face to be cleaned. Then, the protruding line band 32 is relatively moved so as to pat the face to be cleaned and at this time, dust is squeezed by either one of many protrusions 33, 33', isolated dust is guided to a floor nozzle main body 4 by a springing operation and at the time of restoration in the direction of the diameter of the protruding line band 32 and the suction force of a vacuum cleaner. In case of the face to be cleaned is a carpet having long fur, the protrusion 33 high in its height is used and in case the face to be cleaned is a carpet short in fur, the right and the left of the agitator 13 are changed, attached to an inlet chamber 9 and the dust such as waste thread or hair can be taken out without damaging the surface of the carpet by using the protrusion 33' low in height.

The configuration will be explained based on FIG. 4. 1 is an agitator 12
1 is a protrusion strip provided in a spiral shape on the agitator 1, and the protrusion strip 2 has a large number of conical protrusions 3 having the same height on the surface that comes into contact with the floor surface.

もあった。Problems to be Solved by the Invention However, in the above configuration, the conical protrusions 3 are formed on the protrusion band 2 at the same height, so when cleaning a carpet with long limbs and a carpet with short piles, It was difficult to remove dust such as lint and hair from both carpets. In other words, when the height of the protrusion 3 was relatively low, it was difficult to remove dust on a carpet with short piles, but dust on a carpet with long piles. Further, when the height of the protrusion 3 is relatively high, dust can be easily removed from both long and short pile carpets, but there is a risk of damaging short pile carpets. Further, the conventional agitator can only rotate in the same direction, and there is also the problem that the protrusion 3 wears out quickly.

It is obtained by joining the upper and lower body members 6 and 7 via a suction chamber 9 with a lower end opening as a suction port 8 in its front interior, and a turbine chamber 10 in its rear interior. has been done. The turbine chamber 10 is separated from the suction chamber 9 by a partition wall 11, and a rear portion having an opening 12 is formed in an arc shape. Reference numeral 13 indicates an agitator 514 provided in the suction chamber 9 in parallel thereto, and reference numeral 15 indicates the bearing of the agitator 13 provided on both side walls of the suction chamber 9. Reference numeral 15 indicates the suction port 8
A fixed brush 16.17 is attached to the lower surface of the lower body member 7 so as to be parallel to the suction port 8 behind the suction port 8.
are wheels provided at the front and rear of the floor nozzle main body 4 to be positioned at a constant distance from the surface to be cleaned. Reference numeral 18 denotes a substantially semi-cylindrical suction joint that rotatably slides on the rear inner surface of the turbine chamber 10, and a floor nozzle pipe is connected to a cylindrical connection port 19 protruding from a part of the peripheral wall via a ring 20. 21 is rotatably attached, and an extension pipe connected to the suction side of the vacuum cleaner via a hose is detachably connected to the floor nozzle pipe 21.

A shaft body 23 is integrally provided that penetrates the rotating shaft on one side and projects to the outside of the turbine chamber 10 .

タ−１３の他端にもプーリー２５′が設けられている。A power transmission belt 24 transmits the rotation of the turbine 22 to the agitator 13 via a pulley 25 at one end of the agitator 13. A pulley 25' is also provided at the other end of the agitator 13.

ところで、タービン２２はタービン室１０のベルト２４
配設側に片寄らせて配設されている。By the way, the turbine 22 is connected to the belt 24 of the turbine chamber 10.
It is arranged offset to the installation side.

２６、２７は隔壁１１に形成した２個の通気口で、一方

手１８の接続口１９に対向している。Reference numerals 26 and 27 denote two vent holes formed in the partition wall 11. One vent port 26 faces the lower half of the turbine 22, and the other vent port 27 does not face the turbine 22 and is directly connected to the suction joint 18. It faces the connection port 19 of.

２８は切換レバーで、その一部から突出した遮蔽板２９
には上記の通気口２６．２７のいずれか一方と択一的に
連通する開口３０が形成されている。28 is a switching lever, and a shielding plate 29 protrudes from a part thereof.
An opening 30 is formed in the opening 30 to selectively communicate with either one of the vent holes 26 and 27 described above.

上記構成において、今、切換レバー２８を第２図矢印イ
方向に摺動し、その遮蔽板２９の開口３０を通−５＝ 気口２６に連通させたとき、吸込口８→吸込室９→通気

It flows from the extension pipe to the hose to reach the vacuum cleaner.

したがってタービン２２が回転し、その回転力はアジテ
ータ−１３に伝達される。Therefore, the turbine 22 rotates, and its rotational force is transmitted to the agitator 13.

３および３３′が形成されている。By the way, the agitator 13 is constructed by attaching a protrusion band 32 to the outer peripheral surface of the rotor 31 in the longitudinal direction. This protrusion band 32 is made of a flexible material such as rubber, and has many conical protrusions 3 on both sides.
3 and 33' are formed.

また、前記突起３３は高さが高く、突起３３′は高さが
低くなっている。Further, the protrusion 33 has a high height, and the protrusion 33' has a low height.

である。Now, when the agitator 13 is rotating clockwise as shown in FIG. 3, the protrusion band 32 is displaced in the counter-rotation direction when it comes into contact with the surface to be cleaned, and takes a shape along the surface to be cleaned. Thereafter, the protruding strip 32 moves relatively to stroke the surface to be cleaned, and at this time, the dust is squeezed by one of its many protrusions 33, 33' and released from the surface to be cleaned. . The loose dust is effectively guided into the floor nozzle body 4 by the repelling action of the ridge band 32 when it restores itself in the diametrical direction (due to elasticity and centrifugal force) and by the suction force of the vacuum cleaner.

Further, since the protruding band 32 is band-shaped, it is possible to prevent string-like dust such as lint from becoming entangled.

ここで、被掃除面が毛足の長いじゅうたんの場合には、

で入りこんだ糸くずや毛髪を確実に取ることができる。Here, if the surface to be cleaned is a carpet with long piles,
By using a tall protrusion 33, it is possible to reliably remove lint and hair that have penetrated deep into the carpet hair.

用することかできる。In addition, if the surface to be cleaned is a short-pile carpet, the agitator 13 can be installed in the suction chamber 9 by swapping the left and right sides of the agitator 13.
By using the low protrusion 33', it becomes possible to remove dust such as lint and hair without damaging the carpet surface. Also, like this, agitator-1
Since both sides of the protrusion band 32 can be used by switching the right and left sides of the protrusion band 3, the service life is approximately twice as long as that of the conventional device, and the device can be used for a long period of time.

。Effects of the Invention As described above, according to the present invention, the agitator installed inside the floor nozzle body is composed of a rotor and a flexible protrusion band provided in the longitudinal direction of the circumferential surface of the rotor. Protrusions of different heights are formed on the front and back of the band, and by using the protrusions of different heights according to the surface to be cleaned, it is possible to reliably remove lint and hair from any carpet. At the same time, the lifespan can be extended approximately twice as long as that of the conventional method.
