【発明の属する技術分野】
本発明は、刷毛やブレードなどの摺擦部材を設けた回転清掃体によって被清掃面からごみや塵埃を掻き出して吸い込む電気掃除機の吸口体およびこの吸口体を使用した電気掃除機に関する。
【0002】
【従来の技術】
電気掃除機には、その床面開口部に刷毛やブレード状の摺擦部材を設けた所謂回転清掃体を設け、この回転清掃体の回転によって絨毯や畳等の隙間に入り込んだ塵埃を掻き出す方式の吸口体が広く利用されている。この回転清掃体の回転トルクの発生機構には、吸込み空気を利用するエアタービンを用いる方式と、掃除機本体の電源部からフレキシブルホースや延長管内部に設けたワイヤーを通して給電し、モーターを回転させるモーター方式がある。
【0003】
この吸口体において、静電気を利用して床面から効率良く塵埃を吸い込むようにした掃除機が特開平7−59691号公報に開示されている。この吸口体は、床面に対向する吸込みケースの空気吸込み開口部の前端および後端部分の相対向する部位に高圧電極を設置したものである。高圧電極には直流の25kV程度の電圧を印加し、高電圧が印加された電極を床面に接触させることによって、床面の塵埃に帯電した電荷を中和し、集塵効率を向上させるようにしている。
【0004】
また、特開平7−59687号公報や特開平11−216089号公報に開示されている吸口体は、回転清掃体の摺擦部材と絨毯繊維との摩擦より発生する静電気を利用して、集塵効率を向上させるようにしている。
【0005】
【発明が解決しようとする課題】
上記の掃除機は、吸口体内に高圧電源を付設することを前提としており、安全性の問題があり、また、吸口体の重量が増加するため、操作性が悪くなるという問題があった。
【0006】
また、上記の掃除機は、回転清掃体の摺擦部材と絨毯繊維との摩擦を利用するため、絨毯繊維の材質や構造の影響を受けやすく、発生する静電気量が安定しないという問題があった。また、フローリング上では、回転清掃体の摺擦部材がほとんど床面と接触しないために、静電気量がほとんど発生しないという問題があった。
【0007】
本発明の目的は、電気掃除機本体や吸口体に高圧電源を付設することなく、かつ被掃除面の材質や構造に依らず、安定して静電気を発生し、これを利用して被清掃面上のゴミを電気的に中和してゴミの剥離を容易にすることにより、塵埃を効率良く吸い込むことができる軽量な吸口および電気掃除機を提供することにある。
【0008】
また、他の目的は、吸口や被清掃面に過剰に静電気が蓄積することがない吸口および電気掃除機を提供することにある。
【0009】
【課題を解決するための手段】
上記目的は、吸口体内に,回転清掃体の摺擦部材と接触する部材と、導電性繊維を設けることによって達成される。
【0010】
【発明の実施の形態】
[形態例1]
以下、本発明の第1の形態例を図面に従い詳細に説明する。
図1に本形態例による吸口体の内部構成を表す平面図を示す。図1において、101は吸口体下ケース、102は吸口体本体内部と外部(掃除機本体)とを連通する空気通路が形成された自在継手のうち吸口体本体に対して上下方向に回動可能な第1の接続管、103は自在継手のうち前記第1の接続管に対して左右方向に回動可能な第2の接続管、104は回転清掃体,105は回転清掃体104を駆動するための電動機,106は電動機105の駆動を制御する回路基板,107は電動機105と回転清掃体104間を掛け渡す駆動ベルト、108、109は接触部材、110、111は導電性繊維である。
【0011】
図2に本形態例による電気掃除機の外観図を示す。図2において、201は電気掃除機本体、202はホース体、203はハンドルグリップ、204は手元スイッチ、205は延長管、206は吸口体本体である。電気掃除機本体の外郭を形成する本体ケーシングの内側には、吸引力を発生する電動送風機と、この電動送風機の吸引側に集塵室が設けられる。
【0012】
なお、図示してはいないが、ホース体202および延長管205に、吸口体の電動機105に供給する電源線を設けており、第1の接続管102および第2の接続管103には、延長管205を接続した際に、回路基板106に接続するリード線を設けている。さらに、回路基板106と電動機105は、吸口下ケース101内に配設したリード線にて接続する。
【0013】
図3に本形態例による吸口体の平面図のAA断面図を示す。図3において、301は吸口体上ケース、302〜305は回転清掃体の摺擦部材、306は摺擦部材302〜305を固定するロータリコア、307はブラシ室である。
【0014】
次に本形態例の動作を説明する。掃除機使用者がハンドルグリップ203付近に配置されたスイッチ操作部204を操作すると、操作されたスイッチに従った動作モードで電気掃除機本体201内の電動送風機が運転する。電動送風機によって発生した吸引力は、ホース体202、延長管205を通って吸口体206に到達する。それと同時に、ホース体202および延長管205に設けられた電源線から供給された電源が、回路基板106を介して電動機105を駆動し、回転清掃体104が回転する。
【0015】
この回転清掃体104の摺擦部材302〜305と接触するように、接触部材108(109)が設置されている。
【0016】
異なる2種類の材質の物を摺擦すると静電気が発生することが知られている。このときそれぞれの素材の帯電特性は、正極に帯電し易い物質から、負極に帯電し易い物質までを一列に並べた帯電系列と呼ばれる順列により、予想できる。
【0017】
そこで、摺擦部材302〜305の材料として、繰り返し変形疲労につよいナイロンを用い、接触部材109として、ナイロンより負側に帯電しやすい材質、たとえばポリプロピレン樹脂(PP)、アクリロニトリル・ブタジエン・スチレン樹脂(ABS)等を用いる事により、摺擦部材302〜305が正極に、接触部材109が負極に帯電する。
【0018】
接触部材108に発生した負電荷は、上ケース301や下ケース101を通って、導電性繊維110に到達する。導電性繊維とは、アクリルやナイロン繊維の表面に金属皮膜を形成したり、炭素を複合する事により、比抵抗が0.1〜100(Ω/cm)程度に小さくした繊維の事である。
【0019】
そして、この導電性繊維110の負電荷と正極に帯電した回転清掃体104の摺擦部材302〜305との間でコロナ放電が発生する。
【0020】
このコロナ放電により放電した負電荷は、空気中の酸素を電離してイオン化し、マイナスイオンを発生させる。
【0021】
一般に被掃除面上のゴミは正極に帯電している場合が多いことが知られているが、吸口体を前後に移動させる清掃を行うときに、この発生したマイナスイオンがブラシ室307の床下開口部より放出し、被掃除面上のゴミを電気的に中和し、これにより、被掃除面からのゴミの剥離が容易になる。
【0022】
剥離したゴミは、電気掃除機本体201内の電動送風機により発生した吸引力により運ばれ、接続管102、103の内部に形成された管状の空気通路を通って掃除機本体201に吸引される。
【0023】
以上述べたように本実施例によれば、絨毯繊維の材質や構造に依らず、またフローリング上でも安定してイオンを発生することができ、被掃除面上に付着した塵埃を効率良く集塵することができる。
【0024】
また、接触部材108(109)と導電性繊維110(111)は、回転清掃体104のほぼ同一回転円周上に配置しているので、回転清掃体104の回転軸方向(長さ方向)でみて摺擦部材302〜305の最も電位が高い部分が導電性繊維と接触することになり、コロナ放電が最も強く発生する。
【0025】
また、コロナ放電は、放電電極の先端の曲率が小さいほど低い電圧で電界が集中して効率的に発生するようになり、放電効率を上げることができる。本実施例では、導電性繊維110(111)が針状の尖端形状をした無数の放電電極を形成するので、コロナ放電が効率的に発生する。
【0026】
また、金属の針電極ではないので、ユーザが触っても、刺さる危険性がなく、より安全である。
【0027】
また、接触部材108(109)と導電性繊維110(111)は、回転清掃体104の回転軸方向(長さ方向)でみて、ほぼ両端付近に配置しているので、発生したイオンが電気掃除機本体201内の電動送風機により発生した吸引力により吸口体の中央部まで運ばれる。これにより吸口体のほぼ横幅全体にわたって、発生したマイナスイオンがブラシ室307の床下開口部より放出し、被掃除面上のゴミを電気的に中和し、ゴミの剥離が容易になる。
【0028】
また、図4に示すように、接触部材108(109)を設ける代わりに、固定刷毛401を設け、この構成を回転清掃体104の摺擦部材302〜305の材料(ナイロン)より負側に帯電しやすい材質(たとえばアクリル繊維やポリエステル繊維)と、導電性繊維との混紡とすることにより、摺擦部材302〜305と固定刷毛401との摺擦により、摺擦部材302〜305が正極に、固定刷毛401が負極に帯電する。
【0029】
固定刷毛401に発生した負電荷は、混紡してある導電性繊維を介して、正極に帯電した回転清掃体104の摺擦部材302〜305との間でコロナ放電が発生する。
【0030】
このコロナ放電により放電した負電荷は、空気中の酸素を電離してイオン化し、マイナスイオンが発生する。
【0031】
このように、静電気の発生部分と放電部分が一体に形成できるので、コストを低くでき、また取り付けも容易にできる。
【0032】
[形態例2]
以下、本発明の第2の形態例を図面に従い詳細に説明する。
図5に本形態例による吸口体の内部構成を表す平面図を示す。図5において、501は吸口体下ケース、502は吸口体本体内部と外部(掃除機本体)とを連通する空気通路が形成された自在継手のうち吸口体本体に対して上下方向に回動可能な第1の接続管、503は自在継手のうち前記第1の接続管に対して左右方向に回動可能な第2の接続管、504は回転清掃体,505は回転清掃体504を駆動するための電動機,506は電動機505の駆動を制御する回路基板,507は電動機505と回転清掃体504間を掛け渡す駆動ベルトである。
【0033】
図6に本形態例による回転清掃体504を形成するロータリコアの外観図を示す。601はロータリコアで、その溝部分で回転清掃体504の摺擦部材を固定する。
【0034】
図7に本形態例による回転清掃体504を形成する摺擦部材の断面図を示す。701は摺擦部材を縫いつける基材部、702は素材がナイロン繊維で構成された摺擦部材、703は素材がアクリル繊維と導電性繊維の混紡で構成された摺擦部材である。
【0035】
次に本形態例の動作を説明する。掃除機使用者がハンドルグリップ203付近に配置されたスイッチ操作部204を操作すると、操作されたスイッチに従った動作モードで電気掃除機本体201内の電動送風機が運転する。電動送風機によって発生した吸引力は、ホース体202、延長管205を通って吸口体206に到達する。それと同時に、ホース体202および延長管205に設けられた電源線から供給された電源が、回路基板506を介して電動機505を駆動し、回転清掃体504が回転する。
【0036】
この回転清掃体504の回転により、摺擦部材702と703が摺擦し、摺擦部材702が正極に、摺擦部材703が負極に帯電する。
【0037】
摺擦部材703に発生した負電荷は、混紡してある導電性繊維を介して、正極に帯電した摺擦部材702との間でコロナ放電が発生する。
【0038】
このコロナ放電により放電した負電荷は、空気中の酸素を電離してイオン化し、マイナスイオンを発生させる。
【0039】
一般に被掃除面上のゴミは正極に帯電している場合が多いことが知られているが、吸口体を前後に移動させる清掃を行うときに、この発生したマイナスイオンがブラシ室307の床下開口部より放出し、被掃除面上のゴミを電気的に中和し、これにより、被掃除面からのゴミの剥離が容易になる。
【0040】
剥離したゴミは、電気掃除機本体201内の電動送風機により発生した吸引力により運ばれ、接続管502、503の内部に形成された管状の空気通路を通って掃除機本体201に吸引される。
【0041】
以上述べたように本実施例によれば、絨毯繊維の材質や構造に依らず、またフローリング上でも安定してイオンを発生することができ、被掃除面上に付着した塵埃を効率良く集塵することができる。
【0042】
また、コロナ放電は、放電電極の先端の曲率が小さいほど低い電圧で電界が集中して効率的に発生するようになり、放電効率を上げることができる。本実施例では、導電性繊維110(111)が針状の尖端形状をした無数の放電電極を形成するので、コロナ放電が効率的に発生する。
【0043】
また、金属の針電極ではないので、ユーザが触っても、刺さる危険性がなく、より安全である。
【0044】
また、静電気の発生部分と放電部分が一体に形成できるので、コストを低くでき、また取り付けも容易にできる。
【0045】
また、回転清掃体504全体からイオンが発生するので、吸口体のほぼ横幅全体にわたって、発生したマイナスイオンがブラシ室の床下開口部より放出し、被掃除面上のゴミを電気的に中和し、ゴミの剥離が容易になる。
【0046】
【発明の効果】
本発明によれば、吸引力を発生する電動送風機とゴミを貯蔵する集塵部とを有する本体と、被清掃面を摺擦する摺擦部材を有する回転清掃体を床下開口部を有するブラシ室内に設けた吸口体とを備えた電気掃除機において、前記吸口体内に、前記回転清掃体の摺擦部材と接触して帯電する接触部材と、導電性を有し、前記接触部材に発生した電荷を受けて前記ブラシ室内において前記摺擦部材との間にコロナ放電を発生する繊維状部材を設け、前記接触部材と前記繊維状部材は、前記回転清掃体の回転軸方向でみて、ほぼ両端付近に配置したことにより、絨毯繊維の材質や構造に依らず、またフローリング上でも安定してイオンを発生することができ、発生したイオンが電気掃除機本体内の電動送風機により発生した吸引力により吸口体の中央部まで運ばれ、これにより吸口体のほぼ横幅全体にわたって、発生したマイナスイオンがブラシ室の床下開口部より放出して被掃除面上に付着した塵埃を電気的に中和して効率良く集塵することができる。
また、吸口体や掃除機本体に高電圧電源等を付設する必要がないので、吸口や掃除機本体の重量増加に伴う操作性の低下をきたすことがない。
また、発生したイオンを被清掃面に吹き付けることにより、清掃後の被清掃面に多量の静電気を残留させることもない。
また、発生したイオンにより、吸口体本体も除電されるので、砂塵等が静電気で吸口体本体のケース上に付着する事が少なくなるというという効果もある。

BACKGROUND OF THE INVENTION
The present invention relates to a mouthpiece of a vacuum cleaner that sucks dust and dust from a surface to be cleaned by a rotary cleaning body provided with a rubbing member such as a brush or a blade, and a vacuum cleaner using the mouthpiece.
[0002]
[Prior art]
The vacuum cleaner is provided with a so-called rotary cleaning body provided with a brush or blade-like rubbing member at the floor surface opening, and the rotation of the rotary cleaning body scrapes out dust that has entered the gaps of carpets, tatami mats, etc. The mouthpiece is widely used. This rotating cleaning body has a rotational torque generation mechanism that uses an air turbine that uses sucked air, and power is supplied from the power supply unit of the cleaner body through a flexible hose and a wire provided inside the extension tube to rotate the motor. There is a motor system.
[0003]
Japanese Patent Laid-Open No. 7-59691 discloses a vacuum cleaner in which dust is efficiently sucked from the floor surface by using static electricity in this suction body. In this suction body, a high-voltage electrode is installed at the opposite part of the front end and the rear end part of the air suction opening of the suction case facing the floor surface. The high voltage electrode is applied with a DC voltage of about 25 kV, and the electrode to which the high voltage is applied is brought into contact with the floor surface, so that the charge charged to the dust on the floor surface is neutralized and the dust collection efficiency is improved. I have to.
[0004]
The mouthpiece disclosed in Japanese Patent Application Laid-Open No. 7-59687 and Japanese Patent Application Laid-Open No. 11-216089 uses a static electricity generated by friction between the rubbing member of the rotary cleaning body and the carpet fiber to collect dust. I try to improve efficiency.
[0005]
[Problems to be solved by the invention]
The above vacuum cleaner is based on the premise that a high-voltage power supply is provided in the mouthpiece, and has a problem of safety. Further, since the weight of the mouthpiece increases, there is a problem that operability is deteriorated.
[0006]
In addition, since the above vacuum cleaner uses friction between the sliding member of the rotary cleaning body and the carpet fiber, there is a problem that the amount of static electricity generated is not stable because it is easily affected by the material and structure of the carpet fiber. . Further, on the flooring, there is a problem that the amount of static electricity hardly occurs because the rubbing member of the rotary cleaning body hardly contacts the floor surface.
[0007]
The object of the present invention is to stably generate static electricity without attaching a high voltage power source to the vacuum cleaner main body or the suction body, and regardless of the material and structure of the surface to be cleaned, and to use the surface to be cleaned. An object of the present invention is to provide a lightweight suction mouth and vacuum cleaner that can efficiently suck dust by electrically neutralizing the dust and facilitating the separation of the dust.
[0008]
Another object of the present invention is to provide a suction port and a vacuum cleaner in which static electricity does not accumulate excessively on the suction port and the surface to be cleaned.
[0009]
[Means for Solving the Problems]
The above object is achieved by providing a member in contact with the rubbing member of the rotary cleaning body and conductive fibers in the mouthpiece.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
[Example 1]
Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view showing the internal structure of the mouthpiece according to this embodiment. In FIG. 1, 101 is a lower case of the mouthpiece body, 102 is a universal joint formed with an air passage that communicates the inside and outside of the mouthpiece body (vacuum cleaner body), and can be rotated vertically with respect to the mouthpiece body. The first connecting pipe 103 is a second connecting pipe that is rotatable in the left-right direction with respect to the first connecting pipe among the universal joints, 104 is a rotary cleaning body, and 105 is a rotary cleaning body 104. , 106 is a circuit board for controlling the drive of the motor 105, 107 is a drive belt that spans between the motor 105 and the rotary cleaning body 104, 108 and 109 are contact members, and 110 and 111 are conductive fibers.
[0011]
FIG. 2 shows an external view of a vacuum cleaner according to this embodiment. In FIG. 2, 201 is an electric vacuum cleaner main body, 202 is a hose body, 203 is a handle grip, 204 is a hand switch, 205 is an extension pipe, and 206 is a mouthpiece body. An electric blower that generates a suction force and a dust collection chamber on the suction side of the electric blower are provided inside the main body casing that forms the outline of the main body of the vacuum cleaner.
[0012]
Although not shown in the figure, the hose body 202 and the extension pipe 205 are provided with a power supply line for supplying to the motor 105 of the suction body, and the first connection pipe 102 and the second connection pipe 103 are provided with an extension. When the tube 205 is connected, a lead wire connected to the circuit board 106 is provided. Further, the circuit board 106 and the electric motor 105 are connected by a lead wire disposed in the lower suction case 101.
[0013]
FIG. 3 shows an AA cross-sectional view of a plan view of the mouthpiece according to this embodiment. In FIG. 3, reference numeral 301 denotes a suction body upper case, 302 to 305 are sliding members of the rotary cleaning body, 306 is a rotary core for fixing the sliding members 302 to 305, and 307 is a brush chamber.
[0014]
Next, the operation of this embodiment will be described. When the vacuum cleaner user operates the switch operation unit 204 disposed in the vicinity of the handle grip 203, the electric blower in the electric vacuum cleaner main body 201 operates in an operation mode according to the operated switch. The suction force generated by the electric blower reaches the suction body 206 through the hose body 202 and the extension pipe 205. At the same time, the power supplied from the power lines provided on the hose body 202 and the extension pipe 205 drives the electric motor 105 through the circuit board 106, and the rotary cleaning body 104 rotates.
[0015]
The contact member 108 (109) is installed so as to come into contact with the rubbing members 302 to 305 of the rotary cleaning body 104.
[0016]
It is known that static electricity is generated when objects of two different types of materials are rubbed. At this time, the charging characteristics of the respective materials can be predicted by a permutation called a charging series in which materials that are easily charged on the positive electrode to materials that are easily charged on the negative electrode are arranged in a line.
[0017]
Therefore, nylon, which is resistant to repeated deformation fatigue, is used as the material for the rubbing members 302 to 305, and the contact member 109 is a material that is more easily charged on the negative side than nylon, such as polypropylene resin (PP), acrylonitrile butadiene styrene resin ( By using ABS) or the like, the rubbing members 302 to 305 are charged to the positive electrode and the contact member 109 is charged to the negative electrode.
[0018]
The negative charge generated in the contact member 108 reaches the conductive fiber 110 through the upper case 301 and the lower case 101. The conductive fiber is a fiber having a specific resistance reduced to about 0.1 to 100 (Ω / cm) by forming a metal film on the surface of acrylic or nylon fiber or by combining carbon.
[0019]
Corona discharge is generated between the negative charge of the conductive fiber 110 and the rubbing members 302 to 305 of the rotary cleaning body 104 charged to the positive electrode.
[0020]
The negative charge discharged by this corona discharge ionizes oxygen in the air and ionizes it, generating negative ions.
[0021]
In general, it is known that dust on the surface to be cleaned is often charged on the positive electrode. However, when cleaning is performed by moving the suction body back and forth, the generated negative ions are opened under the floor of the brush chamber 307. The waste on the surface to be cleaned is electrically neutralized, thereby facilitating separation of the dust from the surface to be cleaned.
[0022]
The separated dust is carried by the suction force generated by the electric blower in the electric vacuum cleaner main body 201, and is sucked into the vacuum cleaner main body 201 through the tubular air passages formed in the connection pipes 102 and 103.
[0023]
As described above, according to this embodiment, ions can be stably generated regardless of the material and structure of the carpet fiber, and even on the flooring, and the dust adhering to the surface to be cleaned can be efficiently collected. can do.
[0024]
In addition, since the contact member 108 (109) and the conductive fiber 110 (111) are arranged on substantially the same rotation circumference of the rotary cleaning body 104, in the rotation axis direction (length direction) of the rotary cleaning body 104. As a result, the portion with the highest potential of the rubbing members 302 to 305 comes into contact with the conductive fiber, and the corona discharge is generated most strongly.
[0025]
Further, corona discharge is generated efficiently by concentrating the electric field at a lower voltage as the curvature of the tip of the discharge electrode is smaller, and the discharge efficiency can be increased. In this embodiment, the conductive fibers 110 (111) form a myriad of discharge electrodes having a needle-like shape, so that corona discharge is efficiently generated.
[0026]
Moreover, since it is not a metal needle electrode, there is no danger of sticking even if the user touches it, and it is safer.
[0027]
In addition, since the contact member 108 (109) and the conductive fiber 110 (111) are arranged in the vicinity of both ends when viewed in the rotation axis direction (length direction) of the rotary cleaning body 104, the generated ions are cleaned by electric cleaning. It is carried to the central part of the mouthpiece by the suction force generated by the electric blower in the machine main body 201. As a result, the generated negative ions are discharged from the lower floor opening of the brush chamber 307 over almost the entire width of the mouthpiece, and the dust on the surface to be cleaned is electrically neutralized, so that the dust can be easily peeled off.
[0028]
As shown in FIG. 4, instead of providing the contact member 108 (109), a fixed brush 401 is provided, and this configuration is charged more negatively than the material (nylon) of the rubbing members 302 to 305 of the rotary cleaning body 104. By using a blend of a material that is easily damaged (for example, acrylic fiber or polyester fiber) and conductive fiber, the rubbing members 302 to 305 become positive electrodes by rubbing between the rubbing members 302 to 305 and the fixed brush 401, The fixed brush 401 is charged to the negative electrode.
[0029]
The negative charge generated in the fixed brush 401 generates corona discharge between the sliding members 302 to 305 of the rotary cleaning body 104 charged to the positive electrode through the mixed conductive fibers.
[0030]
The negative charge discharged by this corona discharge is ionized by ionizing oxygen in the air, and negative ions are generated.
[0031]
Thus, since the static electricity generation part and the discharge part can be integrally formed, the cost can be reduced and the attachment can be facilitated.
[0032]
[Example 2]
Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 5 is a plan view showing the internal structure of the mouthpiece according to this embodiment. In FIG. 5, 501 is a lower case of the mouthpiece body, 502 is a universal joint formed with an air passage that communicates the inside and outside of the mouthpiece body (vacuum cleaner body), and can be rotated vertically with respect to the mouthpiece body. The first connecting pipe 503 is a second connecting pipe that is rotatable in the left-right direction with respect to the first connecting pipe among the universal joints, 504 is a rotary cleaning body, and 505 drives the rotary cleaning body 504. 506 is a circuit board for controlling the driving of the electric motor 505, and 507 is a drive belt that spans between the electric motor 505 and the rotary cleaning body 504.
[0033]
FIG. 6 shows an external view of a rotary core forming the rotary cleaning body 504 according to this embodiment. Reference numeral 601 denotes a rotary core, which fixes the rubbing member of the rotary cleaning body 504 at the groove portion.
[0034]
FIG. 7 shows a cross-sectional view of the rubbing member forming the rotary cleaning body 504 according to this embodiment. Reference numeral 701 denotes a base material portion on which the rubbing member is sewn, 702 is a rubbing member whose material is made of nylon fiber, and 703 is a rubbing member whose material is composed of a mixture of acrylic fiber and conductive fiber.
[0035]
Next, the operation of this embodiment will be described. When the vacuum cleaner user operates the switch operation unit 204 disposed in the vicinity of the handle grip 203, the electric blower in the electric vacuum cleaner main body 201 operates in an operation mode according to the operated switch. The suction force generated by the electric blower reaches the suction body 206 through the hose body 202 and the extension pipe 205. At the same time, the power supplied from the power lines provided in the hose body 202 and the extension pipe 205 drives the electric motor 505 through the circuit board 506, and the rotary cleaning body 504 rotates.
[0036]
By the rotation of the rotary cleaning body 504, the rubbing members 702 and 703 are rubbed, and the rubbing member 702 is charged to the positive electrode and the rubbing member 703 is charged to the negative electrode.
[0037]
The negative charge generated in the rubbing member 703 generates corona discharge with the rubbing member 702 charged on the positive electrode through the mixed conductive fibers.
[0038]
The negative charge discharged by this corona discharge ionizes oxygen in the air and ionizes it, generating negative ions.
[0039]
In general, it is known that dust on the surface to be cleaned is often charged on the positive electrode. However, when cleaning is performed by moving the suction body back and forth, the generated negative ions are opened under the floor of the brush chamber 307. The waste on the surface to be cleaned is electrically neutralized, thereby facilitating separation of the dust from the surface to be cleaned.
[0040]
The separated dust is carried by the suction force generated by the electric blower in the electric vacuum cleaner main body 201, and is sucked into the vacuum cleaner main body 201 through the tubular air passages formed in the connection pipes 502 and 503.
[0041]
As described above, according to this embodiment, ions can be stably generated regardless of the material and structure of the carpet fiber, and even on the flooring, and the dust adhering to the surface to be cleaned can be efficiently collected. can do.
[0042]
Further, corona discharge is generated efficiently by concentrating the electric field at a lower voltage as the curvature of the tip of the discharge electrode is smaller, and the discharge efficiency can be increased. In this embodiment, the conductive fibers 110 (111) form a myriad of discharge electrodes having a needle-like shape, so that corona discharge is efficiently generated.
[0043]
Moreover, since it is not a metal needle electrode, there is no danger of sticking even if the user touches it, and it is safer.
[0044]
In addition, since the static electricity generating portion and the discharging portion can be integrally formed, the cost can be reduced and the mounting can be facilitated.
[0045]
Further, since ions are generated from the entire rotary cleaning body 504, the generated negative ions are discharged from the opening under the floor of the brush chamber over almost the entire width of the suction body, and the dust on the surface to be cleaned is electrically neutralized. , Easy to peel off dust.
[0046]
【The invention's effect】
According to the present invention, a brush chamber having an underfloor opening includes a main body having an electric blower that generates a suction force and a dust collecting unit that stores dust, and a rotary cleaning body that has a rubbing member that rubs a surface to be cleaned. In the vacuum cleaner provided with the mouthpiece provided in the mouthpiece, in the mouthpiece, a contact member that is charged by contact with the rubbing member of the rotary cleaning body, and a charge that is electrically conductive and is generated in the contact member And a fibrous member for generating corona discharge between the brush member and the rubbing member is provided in the brush chamber, and the contact member and the fibrous member are substantially in the vicinity of both ends when viewed in the rotation axis direction of the rotary cleaning body. It is possible to generate ions stably regardless of the material and structure of the carpet fiber and on the flooring, and the generated ions are sucked by the suction force generated by the electric blower in the main body of the vacuum cleaner. Inside the body As a result, the generated negative ions are discharged from the lower floor opening of the brush chamber and the dust adhering to the surface to be cleaned is electrically neutralized over the entire width of the mouthpiece, thereby efficiently collecting the dust. can do.
Moreover, since it is not necessary to attach a high voltage power supply etc. to a suction body or a vacuum cleaner main body, the fall of operativity accompanying the increase in the weight of a suction mouth or a vacuum cleaner main body is not brought about.
Further, by blowing the generated ions onto the surface to be cleaned, a large amount of static electricity does not remain on the surface to be cleaned after cleaning.
Further, since the mouthpiece body is neutralized by the generated ions, there is an effect that dust and the like are less likely to adhere to the case of the mouthpiece body due to static electricity.
