図1において、吸込具1は床面上の塵埃を空気と一緒に吸い込むためのものであり、上ケース5、下ケース6及びカバー7を組み合わせた細長い筐体2に構成され、平面視において長方形の形状を呈する。吸込具1の前方側面にバッファー9が配置され、壁面との接触時の衝撃を吸収する構造になっている。吸込具1は、例えば、平面視における長手方向の長さが10cm以上且つ30cm以下に形成され、内部には後述する吸込室11と回転ブラシ20が設けられている。この吸込室11は横長の風路を有し、連結管3に接続される吸引パイプを経由して掃除機本体と接続され塵埃を吸い込む構成になっている。また、回転ブラシ20は軸受ケース4で回転可能に支持されている。 In FIG. 1, the suction tool 1 is for sucking dust on the floor surface together with air, and is configured as an elongated housing 2 in which an upper case 5, a lower case 6 and a cover 7 are combined, and is rectangular in a plan view. It exhibits the shape of. A buffer 9 is arranged on the front side surface of the suction tool 1 so as to absorb an impact at the time of contact with a wall surface. The suction tool 1 is formed, for example, with a length in the longitudinal direction of 10 cm or more and 30 cm or less in a plan view, and is provided with a suction chamber 11 and a rotating brush 20 described later inside. The suction chamber 11 has a horizontally long air passage, and is connected to the vacuum cleaner main body via a suction pipe connected to the connecting pipe 3 to suck dust. Further, the rotary brush 20 is rotatably supported by the bearing case 4.

図2及び図3において、吸込具1の長手方向の略中心には、連結管3が配置される。連結管3は、吸引風を生成する掃除機本体(図示省略)に接続された吸引パイプや吸引ホース等に連結される。床面の移動を容易するため、車輪8が配置されている。尚、吸込具1と掃除機本体は、電気掃除機を構成するものである。

In FIGS. 2 and 3, the connecting pipe 3 is arranged at substantially the center of the suction tool 1 in the longitudinal direction. The connecting pipe 3 is connected to a suction pipe, a suction hose, or the like connected to a vacuum cleaner main body (not shown) that generates suction air. Wheels 8 are arranged to facilitate the movement of the floor surface. The suction tool 1 and the vacuum cleaner main body constitute an electric vacuum cleaner.
In FIG. 4, a suction port 10 is formed on the lower surface of the suction tool 1. A rotating brush 20 is arranged in the opening of the suction port 10 and rotates to remove dust on the floor surface to be cleaned.
In FIG. 5, a suction port 12 is formed in the lower part of the connecting pipe 3, and a suction chamber 11 is formed between the suction port 10 and the suction port 12. With this configuration, when the electric blower built in the vacuum cleaner body starts the suction operation, dust-containing air is sucked from the surface to be cleaned through the suction port 10 and passes through the suction chamber 11, the suction port 12, and the connecting pipe 3. It is sucked into the vacuum cleaner body and the dust is collected in the dust collection container arranged in the vacuum cleaner body.

吸込室11内には、回転ブラシ20が回転自在に収納される。回転ブラシ20は、一端が軸受(図示せず)、他端が回転ブラシ保持部(図示せず)に、それぞれ回転自在に軸支され、吸込具1に内蔵された駆動手段(図示せず)により回転駆動される。軸受および回転ブラシ保持部は、下ケース6と軸受ケース4により構成される。また、回転ブラシ20は、筒状基体である回転軸21と、回転軸21の外周面から突出し略全周を覆うように軸方向に螺旋状または直線状に巻かれた清掃部22で構成される。清掃部22は、例えば、繊維質のブラシ毛を用いても良いし、軟質材のブレード状のものでも良い。これらを混合したブラシ毛でも良い。清掃部22は、床面に接触または近接し、回転ブラシ20が回転動作を行う際に、床面上のごみを掻き上げて吸込室11内に取り込む。 The rotating brush 20 is rotatably stored in the suction chamber 11. The rotary brush 20 is rotatably supported by a bearing (not shown) at one end and a rotary brush holding portion (not shown) at the other end, and is a drive means (not shown) built in the suction tool 1. Is driven to rotate. The bearing and the rotating brush holding portion are composed of a lower case 6 and a bearing case 4. Further, the rotary brush 20 is composed of a rotary shaft 21 which is a tubular substrate, and a cleaning portion 22 which protrudes from the outer peripheral surface of the rotary shaft 21 and is spirally or linearly wound in the axial direction so as to cover substantially the entire circumference. To. For the cleaning unit 22, for example, a fibrous brush bristles may be used, or a soft material such as a blade may be used. Brush bristles in which these are mixed may be used. The cleaning unit 22 comes into contact with or is close to the floor surface, and when the rotating brush 20 performs a rotational operation, it scoops up dust on the floor surface and takes it into the suction chamber 11.

回転ブラシ20の清掃部22は、第1清掃部材22aと第2清掃部材22bを有している。この第1清掃部材22aと第2清掃部材22bは、回転ブラシ20を構成する回転軸21の外周面に配置され、且つ、回転軸21の回転方向に対して交互に配置される。また、吸込室11の壁面に回転ブラシ20が回転動作を行う際に第1清掃部材22aおよび第2清掃部材22bと接触する摩擦体26を備え、第1清掃部材22aが正に帯電しやすい材料で形成され、第2清掃部材22bが負に帯電しやすい材料で形成される。尚、摩擦体26は帯電化手段の具体的な構成を示すものである。 The cleaning unit 22 of the rotary brush 20 has a first cleaning member 22a and a second cleaning member 22b. The first cleaning member 22a and the second cleaning member 22b are arranged on the outer peripheral surface of the rotating shaft 21 constituting the rotating brush 20, and are arranged alternately with respect to the rotation direction of the rotating shaft 21. Further, the wall surface of the suction chamber 11 is provided with a friction body 26 that comes into contact with the first cleaning member 22a and the second cleaning member 22b when the rotary brush 20 rotates, and the first cleaning member 22a is easily charged positively. The second cleaning member 22b is made of a material that is easily negatively charged. The friction body 26 shows a specific configuration of the charging means.

摩擦体26は、第1清掃部材22aと第2清掃部材22bを帯電させるため、第1清掃部材22aの帯電列に対して負側で、且つ前記第2清掃部材22bの帯電列に対して正側である帯電列の材料で構成される。さらに、回転ブラシ20の回転動作時に、摩擦体26は第1清掃部材22aと第2清掃部材22bに接触する構造になっている。本構成により、回転ブラシ20が回転動作を行う際に、第1清掃部材22aは摩擦体26と擦れることで正に帯電し、第2清掃部材22bは摩擦体26と擦れることで負に帯電するため、第1清掃部材22aは床面上の負に帯電したごみを静電気で引き寄せ捕集し、第2清掃部材22bは床面上の正に帯電したごみを静電気で引き寄せて捕集することが可能となる。
これにより、回転ブラシ20が吸込室11に取り込めるごみの量が増えるため、床面からのごみの捕集性能を向上することができる。
Since the friction body 26 charges the first cleaning member 22a and the second cleaning member 22b, the friction body 26 is on the negative side with respect to the charging row of the first cleaning member 22a and is positive with respect to the charging row of the second cleaning member 22b. It is composed of the material of the charged column on the side. Further, the friction body 26 has a structure in which the friction body 26 comes into contact with the first cleaning member 22a and the second cleaning member 22b during the rotational operation of the rotary brush 20. According to this configuration, when the rotary brush 20 rotates, the first cleaning member 22a is positively charged by rubbing against the friction body 26, and the second cleaning member 22b is negatively charged by rubbing against the friction body 26. Therefore, the first cleaning member 22a may attract and collect the negatively charged dust on the floor surface by static electricity, and the second cleaning member 22b may attract and collect the positively charged dust on the floor surface by static electricity. It will be possible.
As a result, the amount of dust that can be taken into the suction chamber 11 by the rotary brush 20 increases, so that the dust collection performance from the floor surface can be improved.

また、第1清掃部材22aと第2清掃部材22bは,回転方向に交互に配置される構成に限定されず、例えば、回転ブラシ20の周囲に配置される清掃部22の一部にのみ第1清掃部材22aと第2清掃部材22bが配置される構成でもよい。また、回転軸21の軸方向に沿って第1清掃部材22aと第2清掃部材22bが交互に配置される構成でもよい。 Further, the first cleaning member 22a and the second cleaning member 22b are not limited to the configuration in which they are alternately arranged in the rotation direction, and for example, the first cleaning member 22a and the second cleaning member 22b are only partially arranged around the rotation brush 20. The cleaning member 22a and the second cleaning member 22b may be arranged. Further, the first cleaning member 22a and the second cleaning member 22b may be alternately arranged along the axial direction of the rotating shaft 21.

また、摩擦体26は、第1清掃部材22aの帯電列と第2清掃部材22bの帯電列に対して中間の帯電列である材料で構成してもよい。このような構成にすることで、摩擦体26に対して第1清掃部材22aと第2清掃部材22bを同時に帯電化させることが可能になる。 Further, the friction body 26 may be made of a material that is an intermediate charging row with respect to the charging row of the first cleaning member 22a and the charging row of the second cleaning member 22b. With such a configuration, the friction body 26 can be charged with the first cleaning member 22a and the second cleaning member 22b at the same time.

また、摩擦体26は絶縁体より導電性の高い材料である、例えば、ナイロン、金属等で形成されても良い。本構成により、清掃部22との摩擦により、清掃部22から摩擦体26に移動した電荷を逃がすことができるため、摩擦体26が帯電することを防ぎ、効率よく清掃部22を帯電させることが可能となる。 Further, the friction body 26 may be made of, for example, nylon, metal, or the like, which is a material having higher conductivity than the insulator. With this configuration, the electric charge transferred from the cleaning unit 22 to the friction body 26 can be released due to friction with the cleaning unit 22, so that the friction body 26 can be prevented from being charged and the cleaning unit 22 can be efficiently charged. It will be possible.

次に掻取部について説明する。
図5において、吸込室11の壁面に掻取部27を備える。掻取部27は、吸込室11の壁面から、回転ブラシ20の中心軸に向かって突出し、清掃部22と接触するように形成される。掻取部27は、吸込口10に対し、回転ブラシ20の回転方向に対して下流側かつ、摩擦体26に対し、回転ブラシ20の回転方向に対して上流側に位置している。
Next, the scraping unit will be described.
In FIG. 5, a scraping portion 27 is provided on the wall surface of the suction chamber 11. The scraping portion 27 is formed so as to protrude from the wall surface of the suction chamber 11 toward the central axis of the rotary brush 20 and come into contact with the cleaning portion 22. The scraping portion 27 is located downstream with respect to the rotation direction of the rotary brush 20 with respect to the suction port 10 and upstream with respect to the rotation direction of the rotary brush 20 with respect to the friction body 26.

本構成により、床面で清掃部22に付着したごみを、回転ブラシ20が回転動作を行う際に掻取部27で取り除くことができる。そのため、床面からごみを掻き取った後、清掃部22を清潔な状態にした上で、再度、摩擦体26と接触させて帯電させることができるため、高い帯電量を維持することが可能となる。尚、掻取部27は掻取手段の具体的な構成を示すものである。 With this configuration, dust adhering to the cleaning unit 22 on the floor surface can be removed by the scraping unit 27 when the rotating brush 20 rotates. Therefore, after scraping dust from the floor surface, the cleaning unit 22 can be kept clean and then brought into contact with the friction body 26 again to be charged, so that a high charge amount can be maintained. Become. The scraping unit 27 shows a specific configuration of the scraping means.

次に中和部について説明する。
図5において、吸込口10に対し回転ブラシ20の回転方向に対して下流側に位置する吸込室11の壁面に、中和部28を設ける。中和部28は、清掃部22の近傍に設けられ、絶縁体より導電性の高い材料である、例えば、ナイロン、金属等で形成される。
Next, the neutralization unit will be described.
In FIG. 5, a neutralizing portion 28 is provided on the wall surface of the suction chamber 11 located on the downstream side of the suction port 10 in the rotation direction of the rotary brush 20. The neutralizing section 28 is provided in the vicinity of the cleaning section 22 and is made of, for example, nylon, metal, or the like, which is a material having higher conductivity than the insulator.

本構成により、床面からごみを掻き取った後、清掃部22が中和部28に近づくことで、清掃部22の帯電とは逆の電荷が清掃部22に引き寄せられて、清掃部材22の静電気が中和される。そのため、静電気により清掃部22に付着したごみが清掃部22から離れやすくなり、清掃部22をより清潔な状態に維持し、再度帯電させた際に、高い帯電量を維持することができる。 With this configuration, after the dust is scraped from the floor surface, the cleaning unit 22 approaches the neutralizing unit 28, so that the charge opposite to the charge of the cleaning unit 22 is attracted to the cleaning unit 22 and the cleaning member 22 Static electricity is neutralized. Therefore, the dust adhering to the cleaning unit 22 due to static electricity is easily separated from the cleaning unit 22, and the cleaning unit 22 can be maintained in a cleaner state and a high charge amount can be maintained when the cleaning unit 22 is charged again.

なお、中和部28は、掻取部27よりも回転ブラシ20の回転方向に対して上流側に設けることが望ましい。本構成により、静電気が中和され清掃部材22から離れやすくなったごみを、掻取部27で小さい接触抵抗で脱着できるため、清掃部22が摩耗しにくく、性能を維持することができる。尚、中和部28は中和手段の具体的な構成を示すものである。 It is desirable that the neutralizing portion 28 is provided on the upstream side of the scraping portion 27 with respect to the rotation direction of the rotating brush 20. With this configuration, dust that has been neutralized with static electricity and easily separated from the cleaning member 22 can be attached to and detached from the scraping unit 27 with a small contact resistance, so that the cleaning unit 22 is less likely to wear and performance can be maintained. The neutralizing unit 28 shows a specific configuration of the neutralizing means.

本実施の形態1では、摩擦体26の帯電を防ぐために、摩擦体26を導電性の高い材料で構成したが、例えば、摩擦体26を、接地している商用電源、又は摩擦体26より導電性が高く静電容量の大きい第1導電部材(図示省略)と導線などを介して電気的に接続する構成でも良い。このような構成は、摩擦体26の電荷をさらに逃がしやすくすることが可能となり、より確実に摩擦体26の帯電を防ぐことができる。 In the first embodiment, the friction body 26 is made of a highly conductive material in order to prevent the friction body 26 from being charged. For example, the friction body 26 is made more conductive than a grounded commercial power source or the friction body 26. It may be configured to be electrically connected to a first conductive member (not shown) having a high property and a large capacitance via a conducting wire or the like. Such a configuration makes it possible to further easily release the electric charge of the friction body 26, and it is possible to more reliably prevent the electric charge of the friction body 26 from being charged.

また、本実施の形態1では、中和部28を導電性の高い材料で形成したが、イオンを発生させる放電手段を設け、このイオンによって第1清掃部材22aと第2清掃部材22bの帯電を中和する構成としてもよい。 Further, in the first embodiment, the neutralizing portion 28 is made of a highly conductive material, but a discharge means for generating ions is provided, and the ions charge the first cleaning member 22a and the second cleaning member 22b. It may be configured to neutralize.

本構成により、床面からごみを掻き取った後、清掃部22が回転軸21を介して中和部28と電気的に接続することで、清掃部22の電荷が中和部28に逃げて、清掃部材22の静電気が中和される。そのため、静電気により清掃部22に付着したごみが清掃部22から離れやすくなり、清掃部22をより清潔な状態に維持し、再度帯電させた際に、高い帯電量を維持することができる。 With this configuration, after scraping dust from the floor surface, the cleaning unit 22 is electrically connected to the neutralizing unit 28 via the rotating shaft 21, so that the electric charge of the cleaning unit 22 escapes to the neutralizing unit 28. , The static electricity of the cleaning member 22 is neutralized. Therefore, the dust adhering to the cleaning unit 22 due to static electricity is easily separated from the cleaning unit 22, and the cleaning unit 22 can be maintained in a cleaner state and a high charge amount can be maintained when the cleaning unit 22 is charged again.

図7において、中和部28は、吸込口10に対し回転ブラシ20の回転方向に対して下流側に位置する吸込室11の壁面に設ける構成としてもよい。中和部28は、回転ブラシ20が回転動作を行う際に清掃部22と接触するように設けられ、例えば、接地している商用電源、又は中和部28より静電容量の大きい第2導電部材(図示省略)などと、導線などを介して電気的に接続される構成でも良い。 In FIG. 7, the neutralization unit 28 may be provided on the wall surface of the suction chamber 11 located on the downstream side of the suction port 10 in the rotation direction of the rotary brush 20. The neutralizing unit 28 is provided so that the rotating brush 20 comes into contact with the cleaning unit 22 when performing a rotational operation. For example, the grounded commercial power supply or the second conductive unit having a larger capacitance than the neutralizing unit 28. It may be configured to be electrically connected to a member (not shown) or the like via a conducting wire or the like.

本構成により、床面からごみを掻き取った後、清掃部材22が中和部28と接触して電気的に接続することで、清掃部22の電荷が中和部28に逃げて、清掃部22の静電気が中和される。そのため、静電気により清掃部材22に付着したごみが清掃部22から離れやすくなり、清掃部材22をより清潔な状態に維持し、再度帯電させた際に、高い帯電量を維持することができる。 With this configuration, after scraping dust from the floor surface, the cleaning member 22 comes into contact with the neutralizing section 28 and is electrically connected, so that the electric charge of the cleaning section 22 escapes to the neutralizing section 28 and the cleaning section is used. 22 static electricity is neutralized. Therefore, the dust adhering to the cleaning member 22 due to static electricity is easily separated from the cleaning unit 22, and the cleaning member 22 can be maintained in a cleaner state and can maintain a high charge amount when recharged.

ここで、清掃部22は、中和部28と接触する際に電荷を移動しやすくするため、摩擦体26および中和部28よりは導電性は低いが、導電性が比較的に高い材料で構成することが望ましい。例えば、樹脂材料であれば、カーボンを混合する等して、導電性を上げた材料が挙げられる。 Here, in order to facilitate the transfer of electric charges when the cleaning unit 22 comes into contact with the neutralizing unit 28, the cleaning unit 22 is made of a material having a lower conductivity than the friction body 26 and the neutralizing unit 28, but having a relatively high conductivity. It is desirable to configure it. For example, in the case of a resin material, a material having increased conductivity by mixing carbon or the like can be mentioned.
