(Embodiment 1)
1 is an overall perspective view of an electric vacuum cleaner equipped with a vacuum cleaner suction tool according to Embodiment 1 of the present invention. FIG. 2 is a side sectional view of the vacuum cleaner suction tool according to the embodiment. FIG. 3 is a top view of the vacuum cleaner suction tool according to the embodiment. FIG. 4 is a top view of the vacuum cleaner suction tool according to the same embodiment with the upper member removed.

In the following description, the vacuum cleaner suction tool is abbreviated as a suction tool. In addition, in the following, the arrow C side in FIG. 1 is the left side of the suction tool 1, and the arrow A side in FIG. 1 is the front or front of the suction tool 1 (in the direction in which the user operates the suction tool 1 forward). 1), the arrow B side in FIG. 1 is the rear or rear part of the suction tool 1 (corresponding to the direction in which the user reversely operates the suction tool 1), and the arrow D side in FIG. Will be described.

As shown in FIG. 1, the vacuum cleaner 100 mainly includes, for example, a suction tool 1 that collects dust on a surface to be cleaned such as a floor, a vacuum cleaner body 32 that includes an electric blower 33, and a vacuum cleaner body 32. The hose 31 is detachably connected and the extension pipe 30 is detachably connected to the hose 31.

And, one end of the extension pipe 30 is connected to the hose 31, and the other end of the extension pipe 30 is connected to the suction tool 1 via, for example, a pipe 6 that is movably provided. At the end of the hose 31 on one end side of the extension pipe 30, a hand operation unit 34 for selecting an operation mode in which the user operates the electric blower 33 (for example, suction force such as strong, medium, weak, and off) is provided. It has been. The hand operation unit 34 is provided with a control circuit (not shown) for controlling the electric blower 33 based on the operation mode selected by the user.

As shown in FIGS. 2 to 4, the suction tool main body 1 a includes a lower member 5 having a suction port 15 that constitutes a lower surface of the suction tool main body 1 a, and a front window provided so as to cover the upper portion of the lower member 5. It is comprised from the middle member 4 which has the shape-shaped hole 4a, and the upper member 2 in which the window part 3 which comprises the upper surface of the suction tool main body 1a was formed. A pipe 6 is disposed in the central part at the rear of the suction tool main body 1a. The pipe 6 is sandwiched between the lower member 5 and the upper member 2 of the suction tool main body 1a. At this time, the state of dust or the like entangled with the wearable body 10 can be visually confirmed, for example, by the window 3 of the upper member 2 through the hole 4a of the middle member 4. Thereby, the user can easily recognize the cleaning time of the wear body 10.

In the suction port 15 of the suction tool main body 1a, there is provided a rotating brush 7 that is rotatably supported by the suction tool main body 1a. On the outer peripheral surface of the rotating brush 7, a plurality of brush bodies 8 made of a material (for example, nylon) having a positive charging order are arranged in a spiral shape. On the inner wall in front of the lower member 5 of the suction tool main body 1a, a plate member 9 made of a material having a negative charging order (for example, fluororesin) is provided. And when the rotating brush 7 rotates, the brush body 8 and the plate member 9 of the rotating brush 7 are arrange | positioned so that it may mutually contact.

Further, as shown in FIG. 2, a wear body 10 that rotates in contact with the brush body 8 of the rotating brush 7 when the rotating brush 7 rotates is provided at an upper portion in front of the rotation center axis of the rotating brush 7. ing.

As shown in FIG. 4, the wear body 10 is installed so as to face the suction port 15 of the lower member 5 of the suction tool main body 1 a, and is rotatably supported by the suction tool main body 1 a via the shaft 12. Yes. At this time, the amount (length) of contact between the brush body 8 and the wear body 10 of the rotating brush 7 is not particularly limited as long as the rotation of the rotating brush 7 is not inhibited. However, considering the increase in the amount of dust sucked in, the amount of negative ions generated, the ease of operation of the suction tool 1, etc., 1 to 2 mm is particularly optimal.

Moreover, as shown in FIG. 4, the drive parts 13, such as an electric motor and a turbine, are provided in either one of the right and left of the back of the suction tool main body 1a. The output of the drive unit 13 is transmitted to a gear (not shown) provided at one end of the rotating brush 7 via the belt 14, and the rotating brush 7 rotates in a certain direction. Thereby, as will be described later, the rotation direction of the brush body 8 of the rotating brush 7 can be made constant, so that negative ions generated by contact between the brush body 8 of the rotating brush 7 and the wear body 10 or the plate member 9 are kept constant. It can discharge stably in the direction (front of the suction tool main body 1a). That is, the negative ions are prevented from being sucked into the suction tool 40 by reversing the rotation direction (clockwise) of the brush group during the backward operation of the conventional suction tool 40 shown in FIG. Can be supplied to the surface. At this time, the brush body 8 and the wear body 10 of the rotating brush 7 rotate with each other. Thereby, since the contact position of the brush body 8 of the rotating brush 7 and the wear body 10 is changed and contact at the same position can be avoided, the durability of the wear body 10 is improved.

Further, the length of the wear body 10 in the longitudinal direction is set shorter than the entire length of the rotating brush 7 in the longitudinal direction. The wear body 10 may be divided into a plurality of pieces (for example, 2 to 3 pieces) with respect to the longitudinal direction of the rotating brush 7. Thereby, the contact area (length in the longitudinal direction) between the brush body 8 of the rotating brush 7 and the wear body 10 is shortened, and the load applied to the brush body 8 of the rotating brush 7 is reduced. Operability can be improved.

Note that, for example, a strip-shaped plate 11 made of a material (for example, a fluororesin) having a negative charging order protruding from the surface of the wear body 10 along the longitudinal direction of the wear body 10 may be provided. Thereby, since the brush body 8 of the rotating brush 7 and the wear body 10 do not always contact, durability of the wear body 10 can be improved. Further, since the rotational force of the brush body 8 of the rotating brush 7 can be reliably transmitted to the wear body 10 via the plate 11 protruding from the wear body 10, the increase in the number of rotations of the wear body 10 and the amount of negative ions generated can be reduced. Can be increased.

In this embodiment, as a material having a positive charging order, a material that is easily charged on the positive side, such as wool or Teflon (registered trademark), can be used in addition to nylon. In addition to the fluororesin, a material that is easily charged on the minus side, such as vinyl chloride, can be used as the material having the minus charging order.

The operation and action of the vacuum cleaner suction tool configured as described above will be described below.

First, as shown in FIG. 1, the electric blower 33 is activated by a switch on a circuit provided in the hose 31. At this time, due to the negative pressure generated by the electric blower 33, suction air flowing into the cleaner body 32 is generated inside the hose 31 and the extension pipe 30. Suction air is generated in the suction port 15 of the suction tool main body 1 a through the pipe 6 connected to the extension pipe 30. As a result, dust present on the surface to be cleaned such as the floor surface is sent into the cleaner body 32 by suction air.

At this time, when the drive unit 13 that rotates the rotating brush 7 is an electric motor, the drive unit 13 is also activated by the activation of the electric blower 33. And the motive power of the drive part 13 is transmitted to the rotating brush 7 via the belt 14, and the rotating brush 7 rotates. At this time, when the suction tool 1 is viewed from the left side surface of the suction tool 1 indicated by an arrow C in FIG. 1, the rotation direction of the rotary brush 7 is counterclockwise.

The brush body 8 of the rotating brush 7 comes into contact with the wear body 10 by the rotation of the rotating brush 7, and the wear body 10 is rotationally driven by the driving force of the brush body 8 of the rotating brush 7. At this time, as described above, since the rotating brush 7 rotates counterclockwise, the wear body 10 rotates clockwise. And the rotational drive of the abrasion body 10 can be confirmed by the window part 3 provided in the upper member 2 of the suction tool main body 1a.

Also, the brush body 8 of the rotating brush 7 comes into contact with the wear body 10 or the strip-shaped plate 11 and the plate member 9 provided on the wear body 10 by rotation. Then, the brush body 8 of the rotating brush 7 having the positive charging order and the wear body 10 having the negative charging order or the plate 11 and the plate member 9 provided on the wear body 10 are brought into contact and rubbed. As a result, negative ions are generated due to friction between the brush body 8 of the rotating brush 7 and the wear body 10 or the plate 11 and the plate member 9 provided on the wear body 10.

The generated negative ions are ejected toward the front of the suction tool main body 1a by the brush body 8 of the rotating brush 7 that rotates counterclockwise via the drive unit 13, and are scattered on the surface to be cleaned such as the floor. . At this time, since the plate 11 and the plate member 9 of the wear body 10 are provided facing the longitudinal direction of the brush body 8 of the rotating brush 7, negative ions are wide in the longitudinal direction of the brush body 8 of the rotating brush 7. It spreads in front of the suction tool main body 1a over the region. Thereby, negative ions generated by the contact between the brush body 8 of the rotating brush 7 and the wear body 10 or the plate member 9 can be stably released to the surface to be cleaned in a certain direction (in front of the suction tool body 1a). it can.

According to the present embodiment, the vacuum cleaner suction tool 1 that can improve the durability of the brush body 8 and the wear body 10 of the rotating brush 7 and can stably supply negative ions to the surface to be cleaned, and the same are used. The vacuum cleaner 100 that has been used can be realized.

In the present embodiment, an example has been described in which negative ions are generated by contacting the brush body 8 of the rotating brush 7 with the wear body 10 or the plate 11 and the plate member 9 provided on the wear body 10. Not limited. For example, it is good also as a structure which does not provide either the wear body 10 or the plate member 9. FIG. Thereby, while simplifying the structure of the suction tool 1 and achieving cost reduction, the load added to the brush body 8 of the rotating brush 7 can be reduced, and the operativity of the suction tool 1 can be improved.

In the present embodiment, the example in which the plate 11 is provided on the wear body 10 has been described. However, the wear body 10 alone may be used. Thereby, the structure of the wear body 10 can be simplified and low cost can be achieved. At this time, the wear body 10 may have a configuration in which a plurality of concave portions are provided around the wear body 10 instead of a cylindrical shape, such as an ellipsoid or a gear shape. Thereby, rotation of the rotating brush 7 can be reliably transmitted to the wear body 10.

In the present embodiment, the plate member 9 is illustrated as an example of a flat plate. However, for example, the surface of the rotating brush 7 that contacts the brush body 8 may have an uneven shape. Moreover, it is good also as a shape which provided the uneven surface so that the rotation surface of the brush body 8 of the rotating brush 7 might be followed.

As in the first embodiment, a vacuum cleaner 100 according to the second embodiment of the present invention includes a vacuum cleaner suction tool (hereinafter referred to as “suction tool”) 1 and an electric blower as shown in FIG. The vacuum cleaner main body 32 having a built-in 33, a hose 31, and an extension pipe 30 are included. One end of the extension pipe 30 is connected to the hose 31, and the other end of the extension pipe 30 is connected to the suction tool 1 through the pipe 6. At the end of the hose 31 on one end side of the extension pipe 30, a hand operation unit 34 for selecting an operation mode is provided. The hand operating section 34 is provided with a control circuit (not shown) that controls the electric blower 33 based on the operation mode.

As shown in FIG. 5 to FIG. 8, the suction tool main body 1 a includes an upper member 2 having an appearance and having a window portion 3, a lower member 5 having a suction port 15, and between the upper member 2 and the lower member 5. It is comprised from the middle member 4 which has the hole (not shown) by which the wear body 10 mentioned later is arrange | positioned. As shown in FIG. 1, a pipe 6 is disposed in the central part at the rear of the suction tool main body 1 a. The pipe 6 is sandwiched between the lower member 5 and the upper member 2 of the suction tool main body 1a. At this time, the state of dust and the like entangled with the wearable body 10 can be visually confirmed, for example, by the window 3 of the upper member 2 through the hole of the middle member 4. Thereby, the user can easily recognize the cleaning time of the wear body 10.

Further, in the suction port 15 of the suction tool main body 1a, as shown in FIG. 5, for example, two rotary brushes 7 that scrape dust on the surface to be cleaned such as a floor surface are lower members of the suction tool main body 1a. 5, for example, is detachably attached and rotatable. On the outer peripheral surface of the rotating brush 7, a plurality of brush bodies 8 made of a material having a positive charging order (for example, nylon) are spirally arranged. A plate member 9 made of a material having a negative charging order (for example, Teflon (registered trademark)) is provided on the front inner wall of the lower member 5 of the suction tool main body 1a. And when the rotating brush 7 rotates, the brush body 8 and the plate member 9 of the rotating brush 7 are arrange | positioned so that it may mutually contact.

Further, as shown in FIG. 5, the upper part of the rotating brush 7 in front of the rotation center axis is in contact with the brush body 8 of the rotating brush 7 and rotates when the rotating brush 7 rotates. A wear body 10 comprising 12 is provided.

And the abrasion body 10 faces the suction inlet 15 on the middle member 4 provided so that the upper part of the lower member 5 of the suction tool main body 1a may be covered and which has a window-like hole (not shown) ahead. Is installed. As shown in FIG. 8, the wear body 10 is rotatably supported by a shaft 12 provided so as to penetrate the shaft center of the wear body main body 10a.

Further, one end of the shaft 12 has an insertion portion 20, and the other end of the shaft 12 has a holding portion 21 longer than the length of the insertion portion 20. The insertion portion 20 of the shaft 12 is inserted and held in a holding hole (not shown) formed by the lower member 5 and the upper member 2 constituting the suction tool main body 1a. On the other hand, the holding portion 21 of the shaft 12 is provided with a rotation stopping portion 16 at a part of the holding portion 21. And the rotation prevention part 16 of the holding | maintenance part 21 is engage | inserted by the receiving part 17 provided in the lower member 5 of the suction tool main body 1a, and is pinched | interposed and hold | maintained detachably with the holding body 18 (FIG. 7), and rotates. Fix it freely. That is, the insertion portion 20 of the shaft 12 of the wear body 10 is a holding hole, and the holding portion 21 of the shaft 12 is detachably held by the suction tool main body 1 a by the holding body 18. Thereby, when the wear body 10 rotates, by fixing the shaft 12 in a freely rotatable manner, the shaft 12 can be prevented from being worn, rattled and vibrated, and durability can be improved. Further, by making the length of the holding portion 21 longer than the insertion portion 20 of the shaft 12, the wearer 10 can be easily removed by the user's hand and can be cleaned without directly touching the wearer 10 attached with dust. Therefore, a user-friendly vacuum cleaner can be realized.

In addition, it is preferable to provide the anti-slip | skid part 22 which gave the anti-slip | skid process by knurling process, coating, etc. in the vicinity of the edge part 12a by the side of the holding | maintenance part 21 of the axis | shaft 12, for example. Thereby, the handleability such as removal of the wear body 10 by the user's hand can be further improved, and the wear body 10 can be easily cleaned.

Further, as shown in FIG. 6, a drive unit 13 such as an electric motor or a turbine is provided on either the left or right side behind the suction tool main body 1a. The output of the drive unit 13 is transmitted to a gear (not shown) provided at one end of the rotating brush 7 via the belt 14, and the rotating brush 7 rotates in a certain direction. Thereby, as will be described later, the rotation direction of the brush body 8 of the rotating brush 7 can be made constant, so that negative ions generated by contact between the brush body 8 of the rotating brush 7 and the wear body 10 or the plate member 9 are kept constant. It can discharge stably in the direction (front of the suction tool main body 1a). That is, the negative ions are prevented from being sucked into the suction tool 40 by reversing the rotation direction (clockwise) of the brush group during the backward operation of the conventional suction tool 40 shown in FIG. Can be supplied to the surface. At this time, when the brush body 8 and the wear body 10 of the rotating brush 7 rotate with each other, the contact position between the brush body 8 and the wear body 10 of the rotating brush 7 changes, and contact at the same position is avoided. Therefore, the durability of the wear body 10 is improved.

Further, as shown in FIG. 7, the holding body 18 is arranged so as to form a part of the suction port 15 inside the suction port 15. At this time, the surface forming the suction port 15 of the holding body 18 is formed to be substantially the same surface (including the same surface) as the surface forming the suction port 15 of the suction tool main body 1a. This prevents the brush body 8 of the rotating brush 7 and the sucked dust and the like from being caught, improves the durability of the wear body 10 and the brush body 8 of the rotating brush 7, and facilitates the cleaning operation.

Further, as shown in FIG. 7, the holding body 18 is rotatably provided with a buckle portion 19 for detachably fixing the holding body 18 to the lower member 5 of the suction tool main body 1a. And the buckle part 19 is comprised so that it may become a substantially identical surface (a same surface is included) as the holding body 18, when the holding body 18 is fixed to the lower member 5 of the suction tool main body 1a. The wearable body 10 can be rotatably fixed via the shaft 12 by the holding body 18 fixed to the lower member 5 of the suction tool main body 1 a by the buckle portion 19.

The operation and action of the vacuum cleaner suction tool configured as described above will be described below. In addition, the operation | movement and effect | action which overlap with the vacuum cleaner suction tool of Embodiment 1 are demonstrated easily.

First, as shown in FIG. 1, the electric blower 33 is activated by a switch provided on the hose 31 to generate a negative pressure and generate a suction air flowing into the cleaner body 32. And the dust which exists in to-be-cleaned surfaces, such as a floor surface, is sent into the cleaner main body 32 from the suction inlet 15 of the suction tool main body 1a through the extension pipe 30 and the pipe 6 with the produced | generated suction wind.

At this time, the drive unit 13 composed of an electric motor that rotates the rotary brush 7 is also activated, and the drive unit 13 simultaneously rotates, for example, two rotary brushes 7 via the belt 14. When viewed from the direction indicated by the arrow C in FIG. 1, the rotating brush 7 rotates counterclockwise. When the brush body 8 and the wear body 10 of the rotating rotary brush 7 come into contact with each other, the wear body 10 is rotationally driven in the clockwise direction opposite to the rotation direction of the rotary brush 7. However, since the brush body 8 of the rotating brush 7 and the wear body 10 rotate by contact, the wear body 10 and the brush body 8 of the rotating brush 7 do not rotate in complete synchronization. Therefore, friction is generated by the rotational differential between the brush body 8 and the wear body 10 of the rotating brush 7 that is generated depending on the load state of the surface to be cleaned. Therefore, the configuration in which the wear body 10 is rotated can reduce the load on the brush body 8 of the rotating brush 7 due to the generated friction or the like, for example, as compared with the case where the wear body 10 is fixed, thereby improving the durability.

Then, the brush body 8 of the rotary brush 7 having the plus charge order comes into contact with and rubs against the wear body 10 having the minus charge order or the plate 11 and the plate member 9 provided on the wear body 10 by rotation. . As a result, negative ions are generated due to friction between the brush body 8 of the rotating brush 7 and the wear body 10 or the plate 11 and the plate member 9 provided on the wear body 10.

The generated negative ions are scattered toward the surface to be cleaned such as the floor in front of the suction tool main body 1a by the brush body 8 of the rotating brush 7 that rotates counterclockwise. At this time, negative ions are dispersed over a wide area in front of the suction tool main body 1a by the plate 11 and the plate member 9 of the wear body 10 provided facing the longitudinal direction of the brush body 8 of the rotating brush 7. Thereby, negative ions generated by the contact between the brush body 8 of the rotating brush 7 and the wear body 10 or the plate member 9 can be stably released to the surface to be cleaned in a certain direction (in front of the suction tool body 1a). it can. That is, by rotating the wear body 10, the driving load on the rotating brush 7 such as a frictional force with the wear body 10 can be reduced, and negative ions can be generated efficiently.

However, since it is not possible to reliably prevent dust dirt on the wearable body 10 and wrapping of long dust such as yarn and hair that normally occur during cleaning work, the wearable body 10 cannot always be maintained in a smoothly rotating state. .

Therefore, in the present embodiment, the wear body 10 is configured to be detachable by the holding body 18 in order to maintain the wear body 10 in a smoothly rotating state. Specifically, first, the rotating brush 7 is removed from the suction tool 1. Next, the buckle portion 19 is released and the holding body 18 is removed from the suction tool 1. Finally, the wear body 10 is removed via the shaft 12. Thereby, the suction tool for vacuum cleaners in which the maintenance of the wear body 10 such as when dust is removed, and the vacuum cleaner using the same can be realized.

In addition, according to the present embodiment, the length of the holding portion 21 of the shaft 12 is longer than the length of the insertion portion 20 of the shaft 12 and the anti-slip portion 22 is provided on the holding portion 21, whereby the wear body 10. Can be easily removed.

In addition, according to the present embodiment, the rotation stop 16 of the holding portion 21 of the shaft 12 that prevents wear and backlash is provided on the holding body 18 side, whereby the shaft 12 can be rotationally fixed and the wear body 10 can be mounted. And can be easily removed.

Further, according to the present embodiment, the holding body 18 and the buckle portion 19 are substantially flush with the inner wall of the suction port 15 (including the same face), so that the load caused by the brush body 8 of the rotating brush 7 being caught or the like. And the accumulation of dust on the inner wall of the suction port 15 can be prevented.

In this embodiment, it is needless to say that the same operations and effects as those in Embodiment 1 can be obtained.

Further, it goes without saying that the same effect can be obtained even if the configurations of the above embodiments are adapted to each other.

In each of the above embodiments, the brush body of the rotating brush is configured with a material having a positive charging order, and the wear body, the plate, and the plate member are configured with a material having a negative charging order. However, it is not limited to this. For example, the brush body of the rotating brush may be made of a material having a negative charging order, and the wear body and the plate or plate member may be made of a material having a positive charging order. In other words, the brush body of the rotating brush that comes into contact with the wear body, the plate, and the plate member may be made of materials having different charging orders. Thereby, the same effect and operation can be obtained.

The present invention is useful for a vacuum cleaner suction tool such as a vacuum cleaner that wipes and cleans a floor where a stable supply of negative ions and high durability are required.
