Description

The present invention relates to a vacuum cleaner used, for example, indoors.

  Conventionally, as a vacuum cleaner, as described in Japanese Patent No. 3261342 (Patent Document 1), there is an electrostatic vacuum cleaner that absorbs dust such as dust using static electricity.

  The electrostatic cleaner employs a roller structure. By rolling this roller on the floor surface, dust such as dust on the floor surface is adsorbed to the surface of the roller by static electricity. As a method of collecting dust and other dust adsorbed on the roller, the scraper is brought into contact with the roller to remove dust and other dust on the roller, and the removed dust and other dust are collected in the dust box. The method to be adopted is adopted.

  Unlike the vacuum suction type vacuum cleaner, the electrostatic vacuum cleaner has no noise due to the rotation of the motor or fan, and there is an advantage that indoor air is not contaminated by exhaust.

Japanese Patent No. 3261342 JP 2013-198704 A

The dust is collected by sucking dust such as dust from the suction port 95 located substantially in the center of the rear part of the housing 91.

  However, in the case of the vacuum cleaner disclosed in Patent Document 2, as shown in FIG. 6, the rotation shaft 92 of the side brush 93 is arranged in the vertical direction with respect to the floor surface. Since the circle is indicated by a broken line B, there is a problem that dust such as dust in the corner C of the room is left behind.

  Therefore, an object of the present invention is to provide a vacuum cleaner that can collect dust such as dust at the corner of a room and clean it.

In order to solve the above problems, a vacuum cleaner according to the present invention includes:
In a vacuum cleaner provided with a dust collector having a dust collector main body, a dust collector provided on the outer peripheral surface of the dust collector main body and adsorbing layers on which dust is adsorbed, and a rotating means for rotating the dust collector,

  Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. In the present specification, the same or similar components are denoted by the same reference numerals.

(Embodiment 1)
A vacuum cleaner 100 according to Embodiment 1 of the present invention will be described below with reference to FIGS. 1 and 2.

(General configuration of the vacuum cleaner 100)
As shown in FIG. 1, a dust collector 10 includes a substantially cylindrical dust collector body 1 and an adsorption layer 2 that is provided on the outer peripheral surface of the dust collector body 1 and adsorbs dust such as dust on the floor surface. And have. The dust collector body 1 is rotated in the direction of the arrow R in the figure by a motor 3 as an example of a rotating means (rotation in the direction opposite to the forward direction F).

  The dust D such as dust adsorbed on the surface of the adsorption layer 2 is transferred to the removal mechanism 5 by the rotation of the dust collector 10 by the motor 3. The transferred dust D such as dust is physically separated from the surface of the adsorption layer 2 by the removal mechanism 5 and collected by the collection unit 4. The removing mechanism 5 is made of, for example, a scraper made of rubber or plastic.

  The side brush 20 rotates so as to collect dust such as dust on the side of the casing 31 shown in FIG. 2, that is, on the front and side of the dust collector 10 in the inner direction of the casing 31. The side brush 20 and its peripheral structure will be described in detail later.

  A dust collector 10, a motor 3, a removal mechanism 5, a collection unit 4, and the like are accommodated in the housing 31. A handle 32 is swingably attached to the housing 31.

(Configuration of the dust collector 10)
The dust collector 10 is formed by applying an insulating material such as phthalocyanine to the outer periphery of a cylindrical dust collector body 1 made of a conductor such as aluminum and having a diameter of 10 cm and a length of 30 to 50 cm, for example. Is forming. The end surface of the dust collector body 1 is made of rubber or plastic, for example. The thickness of the adsorption layer 2 is, for example, 20 to 30 μm. As another insulating material used for the adsorption layer 2, for example, polyvinyl carbazole (PVK), a layer containing polycrystalline silicon (for example, vapor deposition or coating film of silicon (Si)), or the like may be used.

(Configuration of adsorption layer 2)
In the first embodiment, the adsorption layer 2 is a charging layer 2 as an example of an adsorption layer, and is charged by a charging device 30 disposed in the vicinity of the charging layer 2. The charged adsorption layer (charged layer) 2 is cleaned by adsorbing dust such as dust on the floor surface by static electricity.

(Configuration of charging device 30)
The charging device 30 includes a conductive cover 7 having an opening only on a surface facing the dust collector 10 and the other surfaces being closed, a grid 9 attached to the opening facing the dust collector 10, tungsten The corona wire 8 is made of the like and stored in the conductive cover 7. The corona wire 8 is held by the conductive cover 7 while being insulated from the conductive cover 7. By applying a voltage to the corona wire 8, static electricity can be generated in the adsorption layer 2.

  The dust D such as dust adsorbed on the adsorption layer 2 is transferred to the removal mechanism 5 by the rotation of the dust collector 10. In the vicinity of the removing mechanism 5, for example, a charge removing device 11 configured by an LED (light emitting diode) or the like is disposed. By irradiating the adsorption layer 2 with light from the charge removing device 11, the electric charge charged in the adsorption layer 2 is removed.

  After the charge of the adsorption layer 2 is removed by the charge removing device 11, dust D such as dust is transferred to the removal mechanism 5, physically separated from the surface of the adsorption layer 2, and collected by the collection unit 4.

(Configuration of side brush 20)
The side brush 20 includes a brush bundle 12 that contacts the floor surface, a brush base 13 in which the brush bundle 12 is implanted, and a rotating shaft 14 that rotates the brush base 13. The brush bundle 12 extends from the brush base 13 so as to follow a virtual frustum generating line. The brush bundle 12 is removably inserted into a fitting hole (not shown) of the brush base 13. Therefore, the brush bundle 12 can be attached to and detached from the brush base 13 so that the brush bundle 12 can be exchanged.

  A connecting ring 15 made of rubber or the like is fixed to the rotating shaft 14 so as to come into contact with an end surface made of rubber or plastic of the dust collector body 1. Accordingly, the rotation of the dust collector body 1 rotates the connecting ring 15 that functions as a friction wheel, and the side brush 20 rotates so as to scrape dust inside.

When the vacuum cleaner 100 is placed on a horizontal floor surface, the vertical line S that intersects the center line of the dust collector 10 on the vertical plane including the center line of the rotating shaft 14 and the center of the rotating shaft When the angle formed by the line is α (α <90 °) and the angle formed by the brush bundle 12 with respect to the center line of the rotating shaft 14 is β,
0 <β <α
The relational expression is established.

(Function of side brush 20)
In Embodiment 1, since the rotation direction of the dust collector 10 is reversed as indicated by an arrow R with respect to the forward direction indicated by the arrow F of the cleaner 100, the connecting ring 15 of the side brush 20 is illustrated in FIG. 1, at the end face of the dust collector body 1, it intersects the center line of the dust collector body 1, and the vertical line segment S intersecting the floor surface is more than 0 degrees and less than 90 degrees clockwise. The end brush of the dust collector main body 1 and the connecting ring 15 are in contact with each other in the region rotated in the range, so that the side brush 20 stirs the dust D from the side to the inside.

  As shown in FIG. 2, the side brush 20 collects dust on the front and side of the casing 31 to the inside of the casing 31, that is, scrapes dust on the front and side of the dust collector 10 on the inside. Since it is adsorbed by the adsorbing layer 2 of the dust collector 10, dust such as dust at the corner C of the room or the wall W can be reliably removed and cleaned.

  For example, when the angle α is 45 degrees and the angle β is 30 degrees, dust such as dust on the side and near the wall can be efficiently collected inside the housing, and the collected dust and the like can be collected by the dust collector 10. It can be removed.

  Here, FIG. 3 shows the result of evaluating dust removal performance by changing the angle β with the angle α fixed. The angle α was 45 degrees, and the angle β was 70 degrees in the study (1), 55 degrees in the study (2), and 30 degrees in the study (3). As a result, in examination (1) and examination (2) in which the angle β is set to 70 degrees and 50 degrees, the rotational resistance due to the contact between the brush bundle 12 and the floor surface is large, resulting in poor rotation of the side brush 20 and good dust removal. Performance was not obtained. In examination (3) in which the angle β is 30 degrees, the rotation of the side brush 20 is good, and dust such as dust on the side and near the wall is collected inside the casing 31 and collected dust such as dust is collected. It could be removed by the dust body 10. From these results, it is confirmed that the relational expression between the angle α and the angle β is satisfied.

  In FIG. 3, the length of the brush is the length of the brush bundle 12, and the height of the brush is the top of the plurality of brush bundles 12 and the upper surface of the brush bundle 12 that comes to the bottom and the floor surface. It is distance.

  Also, in other experimental examples, if the relational expression of 0 <β <α is satisfied, the dust removal performance is good, but if this relational expression is not satisfied, dust remains in the corner of the room and the dust is removed. It turned out that performance worsens and rotation failure of the side brush 20 occurs.

  Moreover, as shown in FIG. 2, by arranging a pair of side brushes 20 on the left and right sides of the dust collector 10, it is possible to clean up to the wall without worrying about the position of the wall surface W and the cleaner user. .

  Further, since the brush bundle 12 can be attached to and detached from the brush base 13, by exchanging the brush bundle 12, the effect of collecting dust such as dust on the side brush 20 can be maintained for a long time. it can.

  Further, since the side brush 20 is rotated by the motor 3 for the dust collector 10 via the end face of the dust collector 10 and the connecting ring 15, a motor dedicated to the side brush 20 is not required, and the manufacturing cost can be reduced.

(Embodiment 2)
FIG. 4 shows a cleaner 200 according to Embodiment 2 of the present invention. The cleaner 200 of Embodiment 2 is different from the cleaner 100 of Embodiment 1 shown in FIG. 1 in the rotation direction R of the dust collector 10. Is the same forward direction as the forward direction F of the cleaner 200, and accordingly, the arrangement of each component is different from that of the first embodiment, but the component itself is substantially the same. Therefore, in FIG. 4, the same constituent elements as those of the first embodiment shown in FIG. 1 are denoted by the same reference numerals as those of the constituent elements of FIG. The configuration and operation will be described below.

  In the vacuum cleaner 200 of the second embodiment, as shown in FIG. 4, the charge removing device 11, the removing mechanism 5, the collecting unit 4, the charging device 30, and the side brush 25 are arranged on the front side of the dust collector 10. Yes.

  The rotating shaft 141 of the side brush 25 is longer than the rotating shaft 14 of the side brush 20 of the first embodiment, extends beyond the center line of the dust collector 10, and is fixed to the rear end portion of the rotating shaft 141. The connecting ring 15 is in contact with the second half region of the end face of the dust collector main body 1 so that the side brush 25 scrapes dust D from the side to the inside.

  The angle α and angle β of the side brush 25 are the same as those in the first embodiment.

  Further, by arranging a pair of the side brushes 25 on the left and right sides of the dust collector 10, the side brush 25 can be cleaned up to the wall without worrying about the position of the wall surface and the cleaner user.

  The brush bundle 12 of the side brush 25 can be attached to and detached from the brush base 13. By exchanging the brush bundle 12, the effect of collecting dust such as dust on the side brush 25 can be maintained for a long time. To be able to.

  In the above configuration, when the dust collector 10 is rotated by the motor 3, the connecting ring 15 in contact with the end face of the dust collector 10 rotates, and the side brush 25 removes dust and other dust from the front and side. The dust is squeezed inside, and the dust is adsorbed by the adsorption layer 2 of the dust collector 10. Then, the adsorption layer 2 is irradiated with light from the electrification removing device 11 to remove charges from the adsorption layer 2, and further, dust D is physically separated from the adsorption layer 2 by the removal mechanism 5 and collected. Part 4 is collected.

  Thereafter, static electricity is generated in the adsorption layer 2 by the charging device 30.

  Also in the vacuum cleaner 200 of the second embodiment, the side brush 25 collects dust on the front and side of the dust collector 10 inward and adsorbs the dust to the dust collector 10. Even trash can be reliably removed and cleaned.

(Embodiment 3)
FIG. 5 shows a vacuum cleaner 300 according to Embodiment 3 of the present invention. The vacuum cleaner 300 of Embodiment 3 differs from the vacuum cleaner 100 of Embodiment 1 shown in FIG. Although the method of transmitting power to is different, the other points are the same as in the first embodiment. Therefore, in FIG. 5, the same components as those of the first embodiment shown in FIG. 1 are denoted by the same reference numerals as those of the components of FIG. Is described below.

  In the vacuum cleaner 300 of the third embodiment, as shown in FIG. 5, the end face gear 19 made of a bevel gear is formed on the end face of the dust collector 10, while the connecting gear 16 made of the bevel gear is formed on the rotating shaft 14 of the side brush 26. The side brush 26 is rotated by meshing the end face gear 19 and the connecting gear 16.

  The angle α and angle β of the side brush 26 satisfy the relational expression of 0 <β <α and are the same as those in the first embodiment.

  Similarly to the first embodiment, the pair of side brushes 26 are arranged on the left and right sides of the dust collector 10 so that they can be cleaned up to the wall without worrying about the positions of the wall surface and the vacuum cleaner user. ing.

  Further, the brush bundle 12 of the side brush 26 can be attached to and detached from the brush base 13. By exchanging the brush bundle 12, the effect of collecting dust such as dust of the side brush 25 can be maintained. I am doing so.

  In the above configuration, the charging device 30 charges the adsorption layer 2 of the dust collector 10. When the dust collector 10 is rotated by the motor 3, the connecting gear 16 meshing with the end face gear 19 of the dust collector 10 rotates, and the side brush 25 moves dust and other dust from the front side to the inside. The dust is adsorbed on the charged adsorption layer 2 of the dust collector 10. Then, the adsorption layer 2 is irradiated with light from the electrification removing device 11 to remove charges from the adsorption layer 2, and further, dust D is physically separated from the adsorption layer 2 by the removal mechanism 5 and collected. Part 4 is collected.

  As described above, also in the third embodiment, the side brush 26 collects the dust on the front and side of the dust collector 10 inward and adsorbs the dust on the adsorption layer 2 of the dust collector 10, so Even dust such as dust can be reliably removed and cleaned.

  Further, since the power is transmitted from the dust collector 10 to the side brush 26 by the meshing of the end face gear 19 and the connecting gear 16, the side brush 26 can be reliably rotated.

  Further, since the side brush 26 is rotated by the motor 3 for the dust collector 10 through the end face gear 19 and the connecting gear 156 of the dust collector 10, a motor dedicated to the side brush 26 is not required, and the manufacturing cost is reduced. it can.

The vacuum cleaner is not limited to an electrostatic vacuum cleaner.

  For example, there is no motor, recovery unit, and removal mechanism, and a dust rotating body is formed by forming an adhesive layer as an example of an adsorption layer on a cylindrical rotating body as an example of a dust collecting body. The side brush 20, 25, or 26 described in the first to third embodiments is disposed on the side of the body, and the rotating body is rotated by a rotating means such as a frame with a handle that rotatably supports the dust collector. Then, dust or the like may be scraped inward with the side brush 20, 25 or 26 to adhere the dust to the adhesive layer.

  In this configuration, the side brush 20, 25, or 26 exhibits the same effect as described above, and has a function of collecting dust on the adhesive layer side.

  Further, when the adhesive layer is periodically removed from the rotating body and a new adhesive layer is exposed, a cleaner and simpler vacuum cleaner can be realized as compared with the first to third embodiments. I can do it.
