Abstract

<P>PROBLEM TO BE SOLVED: To provide a small-sized spinning rotor with good cleanability. <P>SOLUTION: The vacuum cleaner is composed of a spinnable rotor 30 and cleaners 32 which scrape up dust. The rotor 30 has cleaner installing sections 30a which project approximately radially and at which one ends of the cleaners 32 are attached on the end side and in a longitudinal direction and rib bodies 30b which also project approximately radially and is positioned on an opposite spinning direction side of the cleaner 32 and receives the opposite spinning direction side of the cleaner 32 when the rotor 30 spins. When the rotor 30 spins, the opposite spinning direction side of the cleaner 32 is received by the rib body 30b and becomes more elastic to enhance the polishing effect and the cleaning effect on a cleaned surface. Additionally, the cleaner installing section 30a and the rib body 30b are formed in a projecting manner to effectively receive suction air sucked and increase the rotary torque of a spinning rotor 16 while cleaning out the dust by the spinning of the cleaner installing section 30a by which the cleanability is enhanced. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a rotary rotor that rotates and sweeps up dust on a surface to be cleaned, a floor suction tool for a vacuum cleaner incorporating the rotary rotor, and a vacuum cleaner connected to the floor suction tool for the vacuum cleaner. is there.

  This type of conventional rotary rotor will be described with reference to FIGS. FIG. 10 is a perspective view of a state in which an upper cover of a floor suction tool for a vacuum cleaner storing a conventional rotary rotor is removed, and FIG. 11A is a side view of the rotary rotor.

  10 and 11 (a), a conventional rotary rotor 1 includes a rotor 3 having a substantially circular outer cross-sectional shape and rotatably attached to a floor suction tool 2 for a cleaner, and a spiral provided on the outer periphery of the rotor 3. One end is attached to the groove-shaped groove 3 a and the brush-like cleaning body 4 a and the blade-like cleaning body 4 b for scraping dust on the surface to be cleaned are built in the vacuum cleaner floor suction tool 2 via the belt 5. It is rotationally driven by driving means 6 such as an electric motor.

  With the above configuration, when a vacuum cleaner (not shown) is operated and the driving means 6 incorporated in the vacuum cleaner floor suction tool 2 is operated, the rotary rotor 1 rotates, and the brush-like cleaning body 4a and the blade-like cleaning body 4b Dust on the surface to be cleaned such as the floor is picked up, and the dust thus picked up flows from the opening 7 provided in the bottom surface of the floor suction tool 2 for the vacuum cleaner, passes through the suction passage 8, and is not shown in the figure. It is attracted | sucked by the cleaner (for example, refer patent document 1).

  However, since the brush-like cleaning body 4a and the blade-like cleaning body 4b of the conventional rotary rotor 1 are simply attached to the rotor 3 in a radial manner, the strain is weak, and when the rotary rotor 1 is rotated, it is covered. The cleaning performance was never good just by stroking the cleaning surface lightly. In order to make the brush-like cleaning body 4a strong, it is possible to form the brush-like cleaning body 4a with strong bristle or thick brush hair. There was a problem of attaching, and it was not effective.

Therefore, in order to solve the above problem, as shown in FIG. 11 (b), a convex portion 3 b is formed on the outer peripheral surface of the rotor 3 and on the counter-rotating direction side, that is, behind the cleaning body 4. Has been devised in which the convex portion 3b receives the counter-rotation direction side of the cleaning body 4 to make the cleaning body 4 more rigid (for example, see Patent Document 2).

  However, in the configuration of the conventional rotary rotor 1 as shown in FIG. 11B, the cleaning body 4 is implanted in the rotor 3 substantially radially, so that the planting dimension P of the cleaning body 4 is ensured. In addition, from the viewpoint of securing the strength of the rotor 3, it is necessary to secure a predetermined distance G between the center C of the rotor 3 and the lower end of the cleaning body 4. For this reason, the outer diameter size of the rotor 3 cannot be reduced, and there is a problem that it is difficult to reduce the thickness of the floor suction tool 2 for a vacuum cleaner.

  Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the following examples.

Below, the rotary rotor in the 1st Example of this invention is demonstrated using FIGS.
FIG. 1 is a partially broken perspective view of a floor suction tool for a vacuum cleaner incorporating a rotary rotor in the present embodiment.

  In FIG. 1, reference numeral 10 denotes a vacuum cleaner floor suction tool (hereinafter referred to as “floor suction tool 10”) that is connected to a vacuum cleaner (not shown). The outer shell 11 includes an upper case 12 and a suction port 13 on a lower surface. A bumper 15 is provided on the outer periphery to prevent the furniture and the like from being damaged during cleaning, and the rotary rotor 16 in the present embodiment is rotatably stored in the front portion. A rotating rotor chamber 17 communicating with the suction port 13 is disposed. A connecting pipe 18 connected to an electric vacuum cleaner (not shown) is attached to the rear portion of the floor suction tool 10 via an extension pipe (not shown) and the like so as to be tiltable.

  20 is a pair of running rollers provided at the front and rear of the bottom surface of the lower case 14, and when the floor suction tool 10 is placed on a surface to be cleaned such as a wooden floor, the surface to be cleaned and the lower case A predetermined gap is ensured between the bottom surface of 14 and the bottom of the floor suction tool 10 is brought into close contact with the surface to be cleaned by the suction force of the electric vacuum cleaner so that the operability is not deteriorated. is there.

  Reference numeral 21 denotes a suction port that is located substantially in the center of the floor suction tool 10 and behind the rotary rotor 16 and communicates the rotary rotor chamber 17 and the connecting pipe 18. Reference numeral 22 denotes an electric motor serving as a driving unit that rotationally drives the rotary rotor 16 via the belt 23.

  Next, the detailed structure of the rotary rotor 16 in a present Example is demonstrated using FIGS. 2 is a perspective view of the rotary rotor 16, FIG. 3 is a perspective view of a cleaning body of the rotary rotor 16, and FIG. 4 is a side view of the rotary rotor 16.

  2 to 4, the rotary rotor 16 includes a rotor 30 made of a metal material such as aluminum and spirally twisted, and a cleaning body 32 that is detachably attached to the rotor 30 and scrapes up dust on the surface to be cleaned. A bearing holder 33 with a pulley that is press-fitted into one end of the rotor 30 and one end of the belt 23 is stretched, and a bearing holder 34 that is press-fitted into the other end of the rotor 30. Reference numeral 35 denotes a bearing that rotatably supports the bearing holder 33 with pulley and the bearing holder 34 and is held by the inner wall 50 of the suction tool 10.

  As shown in FIG. 3, the cleaning body 32 includes a brush portion 32a made of a plurality of fibers and a base portion 32b in which the lower end of the brush portion 32a is planted or fixed. The brush portion 32a is not limited to a plurality of fibers and may be formed of a blade-like material made of a soft material.

  The rotor 30 protrudes substantially radially, and also has a pair of cleaning body attachment portions 30a having groove portions 31 in which the base portion 32b of the cleaning body 32 is detachably mounted in the longitudinal direction of the distal end side portion. A pair of rib bodies 30b that protrude and are positioned between the pair of cleaning body attaching portions 30a and receive the side opposite to the rotation direction of the cleaning body 32 when the rotor 30 rotates in the direction of the arrow.

  In the present embodiment, as shown in FIG. 4, the longitudinal direction of the cleaning body 32 is obtained by mounting the base portion 32 b of the cleaning body 32 in the groove portion 31 provided on the front end side portion of the cleaning body attaching portion 30 a of the rotor 30. The center line L1 and the longitudinal center line L2 of the cleaning body attaching portion 30a are orthogonal to each other.

Next, several methods for manufacturing and processing the rotor 30 will be described.
In the first method, the material of the rotor 30 is extruded while being twisted by a twist extrusion die, and the target twist angle can be finished in one step. However, warpage and undulation are likely to occur, and it is difficult to ensure accuracy, and this tendency becomes more prominent as the torsion angle increases. The torsion angle is limited to about 360 degrees, and beyond that, it is practically a product. Don't be.

  In the second method, the material of the rotor 30 is extruded while being twisted by a mold, and a rotor 30 having an angle smaller than a target twist angle is once formed. The rotor 30 is twisted to a target twist angle by post-processing. Since it is finished and post-processing is minimized, the rotor 30 with high accuracy can be manufactured with less distortion of the cross-sectional shape. The only drawback is that the process is in two stages.

  In the third method, the material of the rotor 30 is extruded straight and finished by post-processing to the desired twist angle. The accuracy of the product material in one process (linear extrusion) is very high. Originally, the rotor 30 is twisted by post-processing, so that the rotor 30 can be manufactured with low distortion and high accuracy. Further, the twist angle of the rotor 30 can be freely set even in the same mold by post-twisting. As a disadvantage, hollow materials and large-diameter materials are easily deformed in cross-section by twisting, and are not suitable for a large twist angle.

  The fourth method is a production method in which equipment such as a movable plate that rotates in the twisting direction is provided on the same line, the material of the rotor 30 is extruded with a mold, and the twisting process is simultaneously performed to finish the target twisting angle. There is no need to provide a separate twisting process, and there is a merit that the twisting angle can be freely set by the rotational speed of the movable platen, but there is a disadvantage that the equipment becomes complicated.

  Therefore, in manufacturing the rotor 30, it is preferable to appropriately determine the manufacturing method and the processing method in consideration of the cross-sectional shape, material, thickness, strength, torsion angle, required accuracy, and the like of the rotor 30. Moreover, although the typical manufacturing method of the rotor 30 by an extrusion process was described above, since the cleaning body attachment part 30a and the rib body 30b are protrudingly formed especially in the rotor 30 of this invention, an extrusion balance is also sufficient. It tends to collapse and may cause undulation during extrusion. Therefore, in order to ensure the straightness of the product, a drawing process may be performed after the extrusion.

  Next, operation | movement and an effect | action of the rotary rotor 30 by the said structure and the floor suction tool 10 incorporating it are demonstrated using FIG.

  In FIG. 5, when the operation of the electric vacuum cleaner (not shown) and the electric motor 22 of the floor suction tool 10 is started, the rotary rotor 16 rotates in the direction of the solid arrow. And when the front-end | tip of the cleaning body 32 touches a to-be-cleaned surface, since the anti-rotation direction side of the cleaning body 32 is received by the front-end | tip of the rib body 30b located in the anti-rotation direction side of the cleaning body 32, a cleaning body 32 strainers are strengthened, and dust on the surface to be cleaned can be efficiently scraped. The dust that has been scraped up flows from the suction port 13 provided at the bottom of the floor suction tool 10 by the suction force acting by the vacuum cleaner, and is sucked into the vacuum cleaner through the suction port 21 and the connecting pipe 18. .

  As described above, according to the present embodiment, since the strain of the cleaning body 32 is reinforced by the rib body 30b, even if the cleaning body 32 is made of a brush made of a thin fiber, the dust scavenging performance deteriorates. The polishing performance of the surface to be cleaned can be improved.

  Moreover, since the cleaning body attaching part 30a and the rib body 30b are formed so as to protrude from the surface of the rotor 30, the suction air sucked into the vacuum cleaner floor suction tool 10 as indicated by the broken line arrow is efficiently received, Since the rotational torque of the rotary rotor 16 is increased, the motor 22 can be reduced in size, and the rotation of the cleaning body attaching portion 30a and the rib body 30b acts to blow the wind with a fan, and cleaning. The dust scraped out by the body 32 is efficiently wound up, and sufficient cleaning performance can be exhibited even if the suction force of the electric vacuum cleaner is somewhat reduced.

  Further, since the base portion 32b of the cleaning body 32 is attached to the distal end side portion of the cleaning body attachment portion 30a, that is, the longitudinal center line L1 of the cleaning body 32 and the longitudinal direction of the cleaning body attachment portion 30a. Since the center line L2 is substantially orthogonal, it is easy to secure the distance G1 between the mounting side end of the cleaning body 32 and the center of the rotor 30, so that even if the outer diameter dimension of the rotor 30 is reduced accordingly, Since the required strength as the rotary rotor 16 can be ensured, the floor suction tool 10 for a vacuum cleaner can be reduced in size.

  Further, by forming the rotor 30 with a metal material, sufficient strength is ensured even when the cleaning body attaching portion 30a and the rib body 30b are formed protruding from the rotor 30, and the rotary rotor 16 is used for a vacuum cleaner. Even if it is incorporated in the floor suction tool 10 and rotated at high speed, it can be used without any trouble.

  Further, by using the electric motor 22 as a driving means for rotationally driving the rotary rotor 16, even if the carpet surface or a surface to be cleaned with some unevenness is reliably cleaned without significantly reducing the rotation of the rotary rotor 16. It can be performed.

  As shown in FIG. 6, if the cross sections of the cleaning body attaching portion 30 a and the rib body 30 b are curved so that the side receiving the suction air is recessed, the suction air is received more efficiently, and the rotational torque of the rotor 30 is increased. Becomes larger and the cleaning performance can be greatly improved. In addition, any one of the cleaning body attaching portion 30a and the rib body 30b may be curved.

  Moreover, in the said Example, although the electric motor 22 was used as a drive means which drives the rotary rotor 16, you may make it rotate the rotary rotor 16 with a suction wind instead of using the electric motor 22. FIG. Specifically, although not particularly illustrated, a hole for communicating the outside and the rotary rotor chamber 17 is provided in a part of the outer shell 11 of the floor suction tool 10, and high-speed air flowing from the hole is supplied to the rotor 30. Alternatively, the rotating rotor 16 may be rotated by generating a rotational torque by directly contacting the impeller (not shown) provided in the portion or the cleaning body attaching portion 30a and the rib body 30b.

  In the above embodiment, the rotor 30 is provided with a pair of cleaning body attaching portions 30a and a pair of rib bodies 30b alternately. However, as shown in FIG. 7, the cleaning body attaching portions 30a and the rib bodies 30b If two pairs are provided alternately, the rotational torque due to the suction air becomes stronger, the rotation of the rotary rotor 16 becomes smoother, and the cleaning performance can be further improved.

  FIG. 8 is a cross-sectional view of the rotary rotor in the second embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  In FIG. 8, the rotary rotor 38 in the present embodiment is made of a metal material such as aluminum and is spirally twisted, and has a substantially S-shaped cross section 38a, and is formed at the end of the rotor 38a and in the longitudinal direction. The cleaning body attaching portion 38b and the cleaning body 32 having one end mounted on the cleaning body attaching portion 38b and scooping up dust on the surface to be cleaned are configured so that when the rotor 38a rotates, The protrusion 38c that receives the rotation direction side is disposed between the cleaning body attaching portion 38b and the rotation center C of the rotor 38a, and the other configurations are the same as those in the first embodiment.

  As described above, according to the rotary rotor 38 in the present embodiment, when the rotary rotor 38 rotates in the direction of the arrow, the anti-rotation direction side of the cleaning body 32 is received by the protruding portion 38c as shown by the two-dot chain line. The cleaning body 32 becomes stronger and the effect of polishing the surface to be cleaned and the cleaning effect are improved.

  Further, since the rotor 38a has a substantially S-shaped cross section, the suction air sucked into the vacuum cleaner floor suction tool 10 is received efficiently and without waste by the rotor 38a, and the rotational torque of the rotary rotor 38 is increased. And the dust is wound up by the rotation of the rotor 38a, so that the cleaning performance is improved.

  Further, since the base 32b, which is one end of the cleaning body 32, is attached to the cleaning body attaching portion 38b provided at the end of the substantially S-shaped rotor 38a, the base 32b of the cleaning body 32 and the rotor 38a are mounted. Since it is easy to secure the distance to the rotation center C, the outer diameter of the rotor 38a can be reduced correspondingly, and the vacuum suction floor suction tool 10 can be downsized.

  Although not shown in particular, when the hair of the cleaning body 32 is very long, even if the rotary rotor 38 rotates in the direction opposite to the arrow shown in FIG. Since it can be received by 38c, the cleaning body 32 becomes stronger and the polishing effect and the cleaning effect of the surface to be cleaned are improved.

  FIG. 9 is a diagram showing the overall configuration of the electric vacuum cleaner according to the third embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  In FIG. 9, the vacuum cleaner 40 in the present embodiment includes a dust collection chamber 41 that collects dust at the front portion, and a vacuum cleaner body 44 that includes an electric blower chamber 43 that incorporates an electric blower 42 at the rear portion, A hose 45 having one end connected to the cleaner body 44 so as to communicate with the dust collection chamber 41, and an extension pipe 47 having one end detachably connected to a handle pipe 46 provided at the other end of the hose 45. The floor suction tool 10 according to the first embodiment is connected to the other end of the extension pipe 47. The handle pipe 46 is provided with a main body switch 46 a for operating the cleaner main body 44 and a suction tool switch 46 b for operating the electric motor 22 built in the floor suction tool 10.

The operation and action of the vacuum cleaner configured as described above are as follows.
Pull out the power cord (not shown) housed in the vacuum cleaner main body 44, insert the plug (not shown) into an indoor outlet (not shown), the main body switch 46a provided on the handle pipe 46, the suction When the appliance switch 46b is operated, the operation of the electric blower 42 and the electric motor 22 in the floor suction device 10 is started, and accordingly, the object scraped up by the cleaning body 32 from the suction port 13 provided at the bottom of the suction device 10. The dust on the cleaning surface is sucked together with the outside air, reaches the dust collecting chamber 41 through the extension pipe 47, the handle pipe 46, and the hose 45, where the dust contained in the suction air is collected and the cleaned air is It exhausts from the exhaust port (not shown) provided in the rear part of the cleaner body 44.

  According to the present embodiment, since the strain of the cleaning body 32 of the rotary rotor 16 incorporated in the floor suction tool 10 is reinforced by the rib body 30, even if the cleaning body 32 is a brush made of a fiber having a small diameter, The scraping performance is excellent, and the brushing effect is improved by using a thin fiber brush.

  Further, since the cleaning body attaching portion 30a and the rib body 30b are formed so as to protrude from the surface of the rotor 30, the suction air sucked into the vacuum cleaner floor suction tool 10 is efficiently received and the rotation of the rotary rotor 16 is performed. Since the torque is increased, the electric motor 22 can be reduced in size, and further, the rotation of the cleaning body attaching portion 30a and the rib body 30b acts to blow the wind with a fan, and thereby the cleaning body 32 The scraped dust is efficiently wound up, and even if the suction force of the electric blower 42 is somewhat reduced, sufficient cleaning performance can be exhibited.

  Furthermore, since the base portion 32b of the cleaning body 32 is mounted on the tip side portion of the cleaning body mounting portion 30a, it is easy to ensure the distance G1 between the mounting side end portion of the cleaning body 32 and the center of the rotor 30. Therefore, even if the outer diameter of the rotor 30 is reduced by that amount, the necessary strength as the rotary rotor 16 can be ensured. Therefore, the vacuum suction floor suction tool 10 can be further reduced in size and can be used easily. A vacuum cleaner can be provided.

  As described above, the rotary rotor, the floor suction tool for vacuum cleaner, and the vacuum cleaner according to the present invention are small in size, excellent in cleaning performance, and easy to use, and can be used in various vacuum cleaners.
