  According to the electrostatic vacuum cleaner described in Patent Document 1, there is a problem that a charging member for charging the belt portion is required separately.

  Moreover, according to the electrostatic type vacuum cleaner described in Patent Document 2, the dust scraped up by the rotating brush is ionized by the ion generating means disposed inside. In other words, the rotating brush merely scrapes the dust on the floor surface and does not electrostatically adhere the dust on the floor surface by the ion generating means, so there is a problem that the dust collection effect is not sufficient. It was.

  Further, according to the electrostatic dust collector described in Patent Document 3, there is a problem in that it is necessary to separately provide charging means for generating static electricity in the charging layer on the outer surface of the current collector. In addition, there is a problem that uncharged dust cannot be captured and the dust collection effect is not sufficient.

  The present invention was devised to solve such problems. The purpose of the present invention is to provide an electrostatic cleaner that does not require a separate charging member or ionization means and that can sufficiently capture uncharged dust. It is to provide.

  In order to solve the above problems, an electrostatic cleaner of the present invention is an electrostatic cleaner that captures dust on the floor surface by pushing the vacuum cleaner body on the floor surface, and the outer peripheral surface of the first rotating body. The dust collection means that the raising is frictionally charged by sliding in a state where the raising is in contact with the floor surface, and the dust electrostatically attached to the dust collection means is generated by contact charging. And a driving means for rotationally driving the first rotating body and the second rotating body, and the first rotating body pushes the cleaner main body against the floor surface. It is characterized by being rotated.

  According to this configuration, not only the dust on the floor surface can be charged efficiently, but also the charged dust can be peeled off from the floor surface and the uncharged dust can be scraped off from the floor surface. Can be captured and collected.

  In the electrostatic cleaner of the present invention, a charging member that is frictionally charged in contact with the surface of the second rotating body is disposed on the second rotating body.

  According to this configuration, the second rotating body can always be maintained in a charged state, and the dust that is electrostatically attached to the raised portions of the first rotating body that is the dust collecting means can be reliably captured and collected.

  Further, the electrostatic cleaner according to the present invention includes a scraping means for scraping dust adhering to the second rotating body into the dust box.

  According to this structure, the dust adhering to the surface of the 2nd rotary body can be reliably scraped off in a dust box.

  In the electrostatic cleaner of the present invention, the second rotating body is configured to rotate in the same direction as the first rotating body.

  According to this configuration, the contact area between the surface of the first rotating body and the surface of the second rotating body is in contact with each other while rotating in opposite directions. It can be reliably recovered on the two-rotor side.

  In the electrostatic cleaner of the present invention, the charging potential of the second rotating body is higher than the charging potential of the first rotating body.

  According to this structure, dust electrostatically adhering to the raising of the first rotating body is electrostatically adsorbed to the second rotating body having a higher potential, so that the dust is reliably peeled off and collected. Can do.

  In the electrostatic cleaner of the present invention, the first rotating body is made of a conductive member, and the second rotating body is made of an insulating member.

  In the electrostatic cleaner of the present invention, the first rotating body is connected to ground.

  According to this configuration, the charged state of the raising of the first rotating body can be eliminated in a relatively short time by the ground connection. Therefore, charge accumulation by the first rotating body can be prevented, and the discharge risk can be reduced. Further, since the charge accumulation is not saturated, the dust collection effect is continued without decreasing.

  Further, in the electrostatic vacuum cleaner of the present invention, the raised brush has a certain degree of rigidity, so that dust on the floor surface that does not adhere due to static electricity is picked up by the raised brush and directly collected in the dust box at the front position. It is configured.

  According to this configuration, dust such as raw garbage or large dust that does not adhere electrostatically can be collected, so that the dust collection rate is improved.

  Since the electrostatic vacuum cleaner of the present invention is configured as described above, it not only efficiently charges the dust on the floor surface, but also peels off the charged dust from the floor surface or scrapes the uncharged dust from the floor surface. Since it can also be raised, all dust can be captured and collected efficiently.

It is a schematic longitudinal cross-sectional view of the electrostatic vacuum cleaner which concerns on embodiment of this invention. It is an expanded sectional view of a dust collection roller. It is a schematic longitudinal cross-sectional view of the cleaner body which shows the structure of a drive means. It is sectional drawing which shows the other structural example of a dust collection means. It is a schematic sectional drawing which expands and partially shows the peripheral part of a dust collection roller and a peeling roller.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing an overall configuration of an electrostatic cleaner according to an embodiment of the present invention, and FIG. 2 is a schematic longitudinal sectional view of the electrostatic cleaner according to the embodiment of the present invention.

  The electrostatic cleaner 1 according to this embodiment is an electrostatic cleaner that captures dust on the floor surface by pushing the cleaner body 2 forward on the floor surface. Therefore, in the electrostatic cleaner 1 of this embodiment, the operation handle 3 is attached to the cleaner body 2. The operation handle 3 is rotatable in a certain angle range in the front-rear direction (X direction in the figure) with respect to the cleaner body 2, and holds the operation handle 3 to move the cleaner body 2 in the front-rear direction. The dust D on the floor surface F is captured by being pushed forward or pulled back to X.

  Therefore, the electrostatic cleaner 1 according to the present embodiment includes the dust collecting means 10 provided with the raised brush 15 on the outer peripheral surface of the dust collecting roller 16 that is the first rotating body, and the dust electrostatically attached to the dust collecting means 10. And a driving means 30 that rotationally drives the dust collecting roller 16 and the stripping roller 20, and a first rotating body 16. Is configured to rotate (that is, rotate in the R direction) in a direction in which the cleaner body 2 is pushed against the floor surface F (direction X1 in FIG. 2).

  According to this configuration, not only the dust on the floor surface is efficiently charged, but also the dust that has not been charged is scraped off from the floor surface by peeling off the charged dust from the floor surface or by giving the raised brush 15 some degree of rigidity. Since it can also be raised, all dust can be captured and collected efficiently.

  Hereinafter, each component will be described in detail.

  The vacuum cleaner main body 2 has a hollow, substantially rectangular parallelepiped shape, and wheels 12 are attached to the front and rear of the left and right side surfaces 11 respectively. The wheel 12 is made of, for example, conductive rubber, and is attached to the cleaner body 2 by a metal axle (not shown).

  In addition, the bottom surface 13 of the cleaner body 2 is provided with an intake port 14 for taking in the dust D scattered on the floor surface F at a substantially central portion in the front-rear direction X. The intake port 14 has a rectangular shape that is long in the width direction Y orthogonal to the front-rear direction X, and is provided over substantially the entire length in the width direction Y of the cleaner body 2.

  The intake port 14 is provided with a cylindrical dust collecting roller (first rotating body) 16 provided with raised portions 15 over the entire outer peripheral surface. The dust collecting roller 16 is attached in parallel with the width direction Y of the cleaner body 2 by a rotating shaft 17. That is, both ends of the rotating shaft 17 provided along the central axis of the dust collecting roller 16 are supported by the left and right side surfaces 11 of the cleaner body 2 along the width direction Y so as to be freely rotatable. Yes.

  Moreover, the raising | fluff 15 is provided so that the front-end | tip part may protrude in the floor surface F side from the intake port 14 (refer FIG. 6 mentioned later). The protruding length is not particularly limited, but the longer the protrusion length, the better the dust capturing efficiency. In addition, a material that is easily charged to the polarity opposite to that of the dust D is used as the raised brush 15. Here, the raised brush 15 is made of a material that charges the dust D positively and itself is negatively charged.

  In the present embodiment, the raising 15 is frictionally charged by sliding while the raising 15 is in contact with the floor surface F. More specifically, since the brush 15, the dust D, and the floor F rub against each other, the dust D is given a charge (a positive charge in this embodiment). Polar charge (negative charge) is generated. As a result, the dust D is electrostatically attached to the raised hair 15 and is captured and collected.

  As is clear from the above description, in this embodiment, there is no charging means for forcibly (electrically) charging the raised brush 15 and the dust collecting roller 16.

  FIG. 3 is an enlarged cross-sectional view of the dust collection roller 16.

  The dust collecting roller 16 includes a columnar (or cylindrical) cored bar 18 having a rotating shaft 17. The cylindrical first conductive layer 19 a and the second conductive layer 19 b are surrounded by an outer peripheral surface of the cored bar 18. Are stacked in this order. And the raising | fluff 15 is provided in the whole surface of the 2nd conductive layer 19b of outermost layer.

  Here, in the present embodiment, the cored bar 18 is formed of, for example, stainless steel, the first conductive layer 19a is formed of a conductive sponge material, and the second conductive layer 19b is formed of a conductive elastic material. . Moreover, the raising 15 is formed of, for example, conductive acrylic resin fiber, conductive polyester fiber, or the like, and is a fur brush composed of a large number of raising 15. That is, a fiber imparted with conductivity is used. As the conductivity imparting agent, it is possible to use carbon-based powder or metal powder containing carbon black. The cored bar 18, the first conductive layer 19 a, the second conductive layer 19 b, and the raised hair 15 may be formed of at least a conductive member, and the above material is merely an example and is not limited thereto. is not.

  Moreover, it is preferable that the raising | lifting 15 has a certain amount of rigidity in order to lift up the dust which is not charged. When the raised brush 15 has low rigidity and the dust scavenging effect cannot be obtained sufficiently, the raised brush 15 is provided with a separately mixed raised brush having high rigidity (regardless of conductivity). You may make it supplement a scraping function.

  As described above, the raised brush 15 and the dust collecting roller 16 are formed of a conductive material. Therefore, the charge is accumulated in the raised brush 15 and the dust collecting roller 16, so that the charge is saturated, and eventually the discharge may occur. The discharge is likely to occur from both ends of the cored bar 18. Moreover, there is a possibility that a disturbing radio wave is generated by the discharge. Further, when the charges of the raised brush 15 and the dust collecting roller 16 are saturated, no further charging is possible, and the cleaning accuracy may be reduced.

  Therefore, in this embodiment, the current collecting means is connected to the ground. Although not specifically shown in the drawing, as a ground path, a metal that receives the first conductive layer 19a, the second conductive layer 19b, the cored bar 18, the rotating shaft 17, and the rotating shaft 17 from the raised brush 15 or A bearing portion (not shown) made of a conductive resin, a vacuum cleaner body 2 formed of a conductive resin that holds the bearing portion, an axle (not shown) that is a metal attached to the cleaner body 2, and an axle It is configured to be grounded to the ground (in this case, the floor surface F) through wheels 12 that are supported conductive rubber. However, the ground path is not limited to such a path. For example, an earth wire may be disposed between the core metal 18 and the floor surface F so as to be grounded directly from the core metal 18 to the floor surface F. If possible, the ground wire may be extended from the core 18 to the grip portion 3a of the operation handle 3, and the user may grip the grip portion 3a so that the user can ground.

  Returning to FIG. 2, the peeling roller 20, which is the second rotating body, is formed in a cylindrical shape like the dust collecting roller 16, and is in contact with at least the raised brush 15 (in some cases, the dust collecting roller 16 in some cases). A rotating roller that rotates. Therefore, the peeling roller 20 has a rotating shaft 21 provided along the central axis of the peeling roller 20 attached in parallel to the rotating shaft 17 of the dust collecting roller 16. In other words, both ends of the rotary shaft 21 of the peeling roller 20 are rotatably supported by the left and right side surfaces 11 of the cleaner body 2. Further, the rotation direction of the stripping roller 20 is clockwise rotation (rotation in the R direction in FIG. 2), like the dust collection roller 16. Therefore, in the contact area between the dust collecting roller 16 and the peeling roller 20, the rotation directions are opposite to each other. In this way, in the contact area, the dust collecting roller 16 and the peeling roller 20 are in contact with each other while rotating in opposite directions, so that the dust electrostatically attached to the raised brush 15 of the dust collecting roller 16 is charged more than the raised roller. It can be reliably peeled off by the peeling roller 20 having a high potential. The driving means 30 that rotationally drives the dust collecting roller 16 and the peeling roller 20 will be described later.

  Further, the stripping roller 20 is provided with a charging member 22 that contacts the surface of the stripping roller 20 and frictionally charges the surface. The charging member 22 is fixedly held by a member holding portion 23 in the cleaner body 2.

  According to this configuration, the stripping roller 20 can always be maintained in a charged state, and the dust adhering to the dust collecting roller 16 and the raised brush 15 as the dust collecting means 10 can be reliably captured and collected by the stripping roller 20. can do.

  Here, in this embodiment, the peeling roller 20 is formed of a fluorine-based resin. Specifically, PFA (tetrafluoroethylene / perfluoroalkyl vinyl ether copolymer), PTFE (polytetrafluoroethylene), FEP (tetrafluoroethylene / hexafluoropropylene copolymer), ETFE (tetrafluoroethylene / ethylene copolymer). Polymer), PVDF (polyvinylidene fluoride), PCTFE (polychlorotrifluoroethylene), ECTFE (chlorotrifluoroethylene / ethylene copolymer), and the like can be used. The charging member 22 is made of nylon, for example.

  The dust collecting means 10 is connected to the ground to prevent charge accumulation due to the generation and movement of charges. However, since the peeling roller 20 uses a charged state, it is charged once. There is no charge accumulation. Even if electric charges are accumulated, the peeling roller 20 is made of a fluororesin and is an insulating material, so that the occurrence of electric discharge hardly occurs. Therefore, the peeling roller 20 does not need to be connected to the ground. Further, the charging of the peeling roller 20 has the same polarity as that of the raised hair 15 and is higher than the charging potential of the raised hair 15, so that the electrostatically attached dust D can be sufficiently charged to be removed from the raised hair 15.

  Further, the peeling roller 20 is provided with a rubber blade 40 which is a scraping means for scraping dust adhering to the surface into the dust box 50 in the cleaner body 2. The rubber blade 40 is formed in a rectangular shape, and one side of the long side is arranged in parallel along the axial direction of the peeling roller 20 and is in contact with the surface of the peeling roller 20. . Further, the rubber blade 40 is disposed at an acute angle (for example, 30 degrees) toward the upstream side in the rotation direction R with respect to the tangential direction of the surface of the peeling roller 20. The rubber blade 40 arranged in this way is fixedly held by a blade holding part 41 in the cleaner body 2.

  With this configuration, dust attached to the surface of the peeling roller 20 can be surely scraped into the dust box 50.

  In the present embodiment, the diameter of the peeling roller 20 is made larger than the diameter of the dust collecting roller 16, and the arrangement position of the rubber blade 40 is also a position away from the dust collecting roller 16 in the front-rear direction X. Is arranged. This is because if the diameter of the peeling roller 20 is small, the scraping position by the rubber blade 40 cannot be sufficiently separated from the dust collecting roller 16 in the front-rear direction X, so that the dust that has fallen into the dust box 50 again This is because there is a possibility that the brushed 15 and the dust collecting roller 16 are attracted electrostatically and reattached. Therefore, in order to sufficiently separate the rubber blade 40 from the dust collecting roller 16, it is preferable that the diameter of the peeling roller 20 be sufficiently larger than the diameter of the dust collecting roller 16.

  The dust box 50 is disposed below the rubber blade 40 so that an opening 51 for collecting and collecting dust is located. The opening 51 is provided over substantially the entire length in the width direction Y of the cleaner body 2 so as to face the dust D intake port 14 provided on the bottom surface 13 of the cleaner body 2. The dust box 50 is provided on the front side (the pushing direction X1 side) of the intake port 14 of the cleaner body 2, and the lower edge 51 a of the opening 51 faces the front edge 14 a of the intake 14. It is provided so as to incline downward. Thus, by making the lower edge 51a of the opening 51 an inclined surface, dust (for example, raw garbage) D that is not electrostatically adhering to the raised surface 15 of the dust collecting roller 16 from the floor surface F can be obtained. The dust box 50 is collected through the opening 51 without hitting the lower edge 51a.

  Thus, in the electrostatic cleaner 1 of this embodiment, the dust D on the floor surface F that does not adhere due to static electricity is scraped up by the raised brushes 15 and collected in the dust box 50. As a result, dust such as garbage that does not adhere electrostatically can be collected, so that the dust collection rate is improved.

  In addition, although illustration is abbreviate | omitted, this dust box 50 becomes detachable with respect to the cleaner body 2 by opening both the front surface or the upper surface or the side surface or both the front surface and the upper surface of the cleaner body 2. Yes.

  Further, as described above, the raised hair 15 is made of conductive acrylic resin fiber, conductive polyester fiber, or the like, and the peeling roller 20 is made of fluorine resin. As is well known, conductive acrylic resin fibers, conductive polyester fibers, fluorine-based resins, etc. are all materials that easily become negative according to the triboelectric charge train. The charging potential of the fluororesin is higher on the minus side than the charging potential of the polyester fiber. On the other hand, the dust collected and collected here is generally a material that tends to be positively charged by charging friction, such as human hair, fur, wool, nylon, rayon, cotton, hemp, and wood.

  Accordingly, the dust electrostatically attached to the raised brush 15 and the dust collecting roller 16 is electrostatically attached to the stripping roller 20 having a higher potential on the negative side. Further, since the dust collecting roller 16 is connected to the ground, electric charges are easily diffused, and the charged state can be eliminated in a relatively short time. That is, the raised brushes 15 and the dust collecting rollers 16 electrostatically adhering dust on the floor surface are being canceled or canceled when they come into contact with the stripping roller 20, so that the dust adhesion is also reduced. doing. Therefore, in combination with the above-described potential difference, almost all of the dust electrostatically attached to the raised brush 15 and the dust collecting roller 16 is peeled off and electrostatically attached to the peeling roller 20 side.

  FIG. 4 is a schematic longitudinal sectional view of the cleaner body 2 showing the configuration of the driving means 30. However, the illustration of the dust box 50 is omitted in FIG.

  The drive means 30 includes a drive motor 31 disposed on the rear side in the cleaner body 2, a drive gear 32 connected to the drive shaft of the drive motor 31, an intermediate gear 33 meshed with the drive gear 32, The first gear 17a is connected to the rotating shaft 17 of the dust roller 16 and the second gear 21a is connected to the rotating shaft 21 of the peeling roller 20, and the intermediate gear 33 is connected to the first gear 17a and the second gear 21a. The gear 21a is meshed with both sides. That is, the two rollers of the dust collecting roller 16 and the peeling roller 20 are rotationally driven by one system of driving means. Further, as the first gear 17a and the second gear 21a mesh with the same intermediate gear 33, the dust collecting roller 16 and the stripping roller 20 are driven to rotate in the same direction (R direction) as described above. In the contact area, the rotations are opposite to each other.

  The drive motor 31 is driven using the rechargeable battery 35 (see FIG. 1) as a power source. In the present embodiment, the rechargeable battery (rechargeable battery) 35 is attached to the upper part of the operation handle 3 and below the grip portion 3a. By attaching to the lower side of the grip portion 3a, the detaching work for charging and the attaching work after charging become easy. Note that the rechargeable battery 35 may be charged by being connected to a commercial power supply while being attached to the operation handle 3 regardless of whether it is a detachable type or a fixed type. Further, the charging location 35 may be attached to the inside of the cleaner body 2.

  In addition, a switch for controlling on / off of the drive motor 31 is not shown, but it may be provided in the vicinity of the grip portion 3a.

  FIG. 5 is a cross-sectional view showing another configuration example of the dust collecting roller.

  The dust collecting roller 16a shown in FIG. 5 has a configuration in which raised hairs 15 are directly provided on the entire surface of a columnar (or cylindrical) cored bar 18 having a rotating shaft 17. Therefore, in this dust collecting roller 16a, the length of the raising 15 is long. Similar to the dust collecting roller 16, the cored bar 18 is made of, for example, stainless steel, and the raised portions 15 are made of, for example, conductive acrylic resin fiber, conductive polyester fiber, or the like.

  Next, the operation of the electrostatic cleaner 1 having the above configuration will be described with reference to FIG. However, the dust collecting roller will be described as the dust collecting roller 16 shown in FIGS. 2 and 3. FIG. 6 is a schematic cross-sectional view showing a part of the periphery of the dust collecting roller 16 and the peeling roller 20 in an enlarged manner.

  When the user turns on a switch (not shown) of the drive motor 31, the drive motor 31 starts to rotate, and accordingly, the dust collecting roller 16 and the peeling roller 20 start to rotate in the R direction.

  In this state, the user cleans the floor F while repeatedly pushing and pulling the cleaner body 2 back and forth.

  At this time, the raised hair 15 planted on the dust collecting roller 16 also starts to rotate in the R direction, and when it comes into contact with the floor surface F, it is greatly curved toward the rear side of the rotation and slidably contacted with the floor surface F. In particular, when pushing forward the cleaner body 2 (when sliding in the X1 direction in the figure), the direction of rotation of the raised brush 15 and the direction pushing forward the cleaner body 2 are the same direction. A large force is applied to increase the charge amount. Therefore, the dust D scattered on the floor surface F by the friction of the raised hairs 15 is charged to the positive side and floated, and the floated dust D is electrostatically attracted to the dust collecting roller 16 charged to the negative side. Adhere by static electricity.

  The dust D electrostatically attached to the raised brush 15 and the dust collecting roller 16 is frictionally charged and attached to the peeling roller 20 charged to the negative side by the charging member 22, and the surface of the peeling roller 20 by the rubber blade 40. The dust D adhering to is scraped off and collected in the dust box 50.

  On the other hand, dust Da such as raw garbage that does not adhere electrostatically is scraped up from the floor surface F by the raised hairs 15 and collected directly into the dust box 50 through the opening 51.

  When the cleaner body 2 is pulled back, the direction of rotation of the raised brush 15 and the direction of pulling back the cleaner body 2 are opposite to each other, so that only a small force is applied to the raised brush 15 and the amount of charge is reduced. As a result, the dust capturing / collecting power when the vacuum cleaner body 2 is pulled back is reduced, but it is not completely impossible to collect the dust. Moreover, in the electrostatic cleaner 1 of this embodiment, it is assumed that dust is captured and collected by pushing the cleaner body 2 forward. Therefore, there is no particular problem even if the dust is not sufficiently captured and collected when it is pulled back.

  The present invention can be implemented in various other forms without departing from the spirit or main features thereof. Therefore, the above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. The scope of the present invention is set forth in the claims, and is not restricted by the text of the specification. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  The present invention greatly contributes to an electrostatic cleaner in general that captures dust on the floor surface by pushing the vacuum cleaner body on the floor surface.
