Description
本発明は、電気掃除機の吸口体およびそれを用いた電気掃除機に関する。 The present invention relates to a mouthpiece of a vacuum cleaner and a vacuum cleaner using the same.
従来技術として、吸込口を有する吸込具本体（吸口本体）に、被掃除面上を自由転動する起毛布ローラ体を取り付けた電気掃除機の吸込具（吸口体）において、前記起毛布ローラ体の回転方向の一方向の動きを規制し、回転方向の逆方向の動きをフリーとする制動手段を備えた技術が提案されている（例えば、特許文献１参照）。 As a prior art, in a suction tool (suction body) of a vacuum cleaner in which a suction cloth body (suction body) having a suction port is attached with a raised cloth roller body that freely rolls on the surface to be cleaned, the brushed cloth roller body A technique has been proposed that includes a braking means that restricts movement in one direction of rotation of the rotation direction and frees movement in the direction opposite to the rotation direction (see, for example, Patent Document 1).
しかしながら、特許文献１に記載の制動手段は、吸込具本体（吸口本体）の起毛布ローラ体周面と対向する壁面との間に形成された楔状空間と、該楔状空間内に配置されて前記起毛布ローラ体周面と前記壁面との間に介在し、該起毛布ローラ体の回転方向の一方向の動き時に該楔状空間内の奥に嵌入して該起毛布ローラ体の動きを規制する制動輪とから構成されているため、構造が複雑であった。また砂ゴミ等の侵入や糸からみにより制動輪の動きが妨げられ、起毛布ローラ体の制動機能が損なわれる恐れがあった。そのため吸込具（吸口体）後退時に、起毛布ローラ体の回転が規制され、吸込具（吸口体）後方の塵埃が集塵されなかったり、吸込具（吸口体）前進時に起毛布ローラ体が回転して、吸込口に吸引された塵埃が起毛布ローラ体の後方に出ていく恐れがあった。 However, the braking means described in Patent Document 1 is disposed between the wedge-shaped space formed between the circumferential surface of the raised cloth roller body and the wall surface of the suction tool main body (suction port main body) and the wedge-shaped space. The raised cloth roller body is interposed between the circumferential surface and the wall surface, and is inserted into the wedge-shaped space when the raised cloth roller body moves in one direction of rotation to restrict the movement of the raised cloth roller body. Since it is composed of braking wheels, the structure is complicated. In addition, the movement of the braking wheel is hindered by the intrusion of sand dust or the like and the thread entanglement, and the braking function of the raised cloth roller body may be impaired. Therefore, when the suction tool (suction body) is retracted, rotation of the brushed cloth roller body is restricted, so that dust behind the suction tool (suction body) is not collected, or when the suction tool (suction body) moves forward, the raised cloth roller body rotates. As a result, the dust sucked into the suction port may come out behind the brushed cloth roller body.
本発明は、簡単な構成で、起毛布ローラ体の回転方向の一方向の動きを規制し、回転方向の逆方向の動きを許容することで、吸口体後退時の集塵性能を向上させた電気掃除機の吸口体およびそれを用いた電気掃除機を提供することを目的とする。 The present invention has a simple configuration, restricts the movement of the brushed cloth roller body in one direction of rotation, and allows the movement in the reverse direction of the rotation direction to improve the dust collection performance when the suction body moves backward. An object of the present invention is to provide a mouthpiece of an electric vacuum cleaner and an electric vacuum cleaner using the same.
本発明は、清掃面と略平行な回転軸を有する第１回転清掃体と、前記第１回転清掃体を支持する吸込室と、前記第１回転清掃体の後方に、前記回転軸と平行な軸を有し、前記清掃面と接触する第２回転清掃体と、を備え、該第２回転清掃体の表面には、刷毛体もしくは弾性体を設け、該刷毛体もしくは弾性体は、当該吸口体の一部に接触するように設けられており、当該吸口体の後進時に前記第２回転清掃体の回転動作を許容し、かつ前進時に前記第２回転清掃体の回転動作を規制するように、円周方向に傾斜して設けられていることを特徴とする。 The present invention includes a first rotary cleaning body having a rotation axis substantially parallel to a cleaning surface, a suction chamber that supports the first rotary cleaning body, and a rear side of the first rotary cleaning body, parallel to the rotation axis. A second rotary cleaning body that has a shaft and contacts the cleaning surface, and a brush body or an elastic body is provided on a surface of the second rotary cleaning body, and the brush body or the elastic body has the suction port It is provided so as to come into contact with a part of the body, so that the rotational operation of the second rotary cleaning body is allowed when the suction body moves backward, and the rotational operation of the second rotary cleaning body is restricted when moving forward. It is characterized by being inclined in the circumferential direction.
本発明によれば、簡単な構成で、起毛布ローラ体の回転方向の一方向の動きを規制し、回転方向の逆方向の動きを許容することで、吸口体後退時の集塵性能を向上させた電気掃除機の吸口体およびそれを用いた電気掃除機を提供することができる。 According to the present invention, with a simple configuration, the movement of the brushed fabric roller body in one direction of rotation is restricted, and the movement in the reverse direction of the rotation direction is allowed to improve the dust collection performance when the suction body moves backward. It is possible to provide a suction body of a vacuum cleaner and a vacuum cleaner using the same.

The air passages are connected so as to communicate with each other, and are configured to be extendable. FIG. 1 illustrates a state in which the extension pipe 5 is shortest.
図２は、本発明の実施形態に係る吸口体６の上面図である。 FIG. 2 is a top view of the mouthpiece 6 according to the embodiment of the present invention.
図２に示すように、吸口体６は、上から見て略Ｔ字形状を呈する吸口ケース１０と、吸口ケース１０に連結される吸口継手１３とを備えている。 As shown in FIG. 2, the mouthpiece 6 includes a mouthpiece case 10 having a substantially T shape when viewed from above, and a mouthpiece joint 13 connected to the mouthpiece case 10.
吸口ケース１０は、上から見て、左右方向（幅方向、後術する第１回転清掃体２０の回転軸方向）に細長く形成された吸口本体１１と、吸口本体１１の長手方向の中央部に吸口継手１３と連結される連結部１２とを備えている。連結部１２には、吸口本体１１と吸口継手１３とを連通させる流路Ｒ（図３参照）が形成されている。 The mouthpiece case 10 has a mouthpiece body 11 that is elongated in the left-right direction (width direction, the rotation axis direction of the first rotary cleaning body 20 to be operated later), and a center portion in the longitudinal direction of the mouthpiece body 11 when viewed from above. A connecting portion 12 connected to the suction joint 13 is provided. A flow path R (see FIG. 3) that connects the suction body 11 and the suction joint 13 is formed in the connecting portion 12.
吸口本体１１には、前端面から左右側面にかけてバンパ１１ａが設けられている。バンパ１１ａは、ゴムやエラストマー等の弾性材料から形成されており、使用時に吸口本体１１内の気密を保持するとともに、電気掃除機１（図１参照）の使用時に吸口本体１１が家具等に衝突した際に、当該家具等の傷付きを防止するとともに、と吸口本体１１への衝撃を吸収する緩衝材の役割を果たしている。 The mouthpiece main body 11 is provided with a bumper 11a from the front end surface to the left and right side surfaces. The bumper 11a is made of an elastic material such as rubber or elastomer. The bumper 11a keeps the airtightness in the mouthpiece main body 11 when used, and the mouthpiece main body 11 collides with furniture or the like when the vacuum cleaner 1 (see FIG. 1) is used. When it does, while preventing the said furniture etc. from being damaged, it plays the role of the shock absorbing material which absorbs the impact to the suction mouth main body 11.
吸口体６は、吸口本体１１の長手方向（左右方向）の中央部に発光手段７０を備えている。この発光手段７０は、操作管４の手元操作スイッチＳＷを操作することなどによって選ばれた、電動送風機２ａの運転の強中弱状態（例えば強運転時には赤色、中運転時にはオレンジ色、弱運転時は緑色）を表示する。 The mouthpiece 6 includes a light emitting means 70 at the center in the longitudinal direction (left-right direction) of the mouthpiece body 11. The light emitting means 70 is selected by operating the hand operation switch SW of the operation tube 4 or the like, for example, a strong, medium or weak state of operation of the electric blower 2a (for example, red for strong operation, orange for medium operation, orange for weak operation) Is green).
吸口継手１３は、連結部１２に対して回動自在に連結される第１接続管１４と、この第１接続管１４に対して回動自在に連結される第２接続管１５とを備えている。 The suction joint 13 includes a first connecting pipe 14 that is rotatably connected to the connecting portion 12, and a second connecting pipe 15 that is rotatably connected to the first connecting pipe 14. Yes.
第１接続管１４は、図２に示す上面図において略半トラック形状を呈し、連結部１２と連結される一部開口した流路を有する円筒形状の軸１４ａを有している。軸１４ａは、軸方向が吸口本体１１の長手方向であって、軸１４ａの両端部が連結部１２に形成された一対の軸受部１２ｇ（図４参照）に支持されている。また、第１接続管１４は、床面（清掃面）に対して略平行な状態から略垂直な状態まで（上下方向に）回動可能となるように構成されている。すなわち、第１接続管１４を吸口ケース１０に対して軸１４ａを支点として回動させることによって、延長管５を床面に略平行な状態と略垂直な状態との間において回動させることができる。 The first connection pipe 14 has a substantially semi-track shape in the top view shown in FIG. 2, and has a cylindrical shaft 14 a having a partially open flow passage connected to the connecting portion 12. The shaft 14 a is supported by a pair of bearing portions 12 g (see FIG. 4) in which the axial direction is the longitudinal direction of the mouthpiece body 11 and both ends of the shaft 14 a are formed in the connecting portion 12. Further, the first connecting pipe 14 is configured to be rotatable from a substantially parallel state to a substantially vertical state (up and down direction) with respect to the floor surface (cleaning surface). That is, by rotating the first connection pipe 14 with respect to the suction case 10 with the shaft 14a as a fulcrum, the extension pipe 5 can be rotated between a state substantially parallel to the floor surface and a state substantially vertical. it can.
第２接続管１５は、第１接続管１４に対して長手方向に（図２の紙面時計回り方向および反時計回り方向に）回動可能となるように構成されている。これにより、例えば、延長管５を床面に対して略垂直にした状態から、延長管５を床面に略平行な状態にむけて倒すことができる。 The second connection pipe 15 is configured to be rotatable with respect to the first connection pipe 14 in the longitudinal direction (clockwise and counterclockwise in FIG. 2). Thereby, for example, the extension pipe 5 can be brought down to a state substantially parallel to the floor surface from a state where the extension pipe 5 is substantially perpendicular to the floor surface.
また、第２接続管１５には、給電が行われる給電端子１５ａ、１５ａが設けられている。なお、本実施形態例の電気掃除機１（図１参照）では、吸口体６に給電する電力を、掃除機本体２からホース部３、操作管４、延長管５を通じて供給するように構成されている。 The second connection pipe 15 is provided with power supply terminals 15a and 15a for supplying power. In addition, in the vacuum cleaner 1 (refer FIG. 1) of this embodiment example, it is comprised so that the electric power supplied to the suction body 6 may be supplied from the cleaner body 2 through the hose part 3, the operation tube 4, and the extension tube 5. ing.
このような吸口継手１３は、例えば延長管５（図１参照）を床面に対して略垂直とした状態において、その延長管５を左右方向（長手方向）に倒すことができることで、操作管４（グリップ４ａ）を時計回りあるいは反時計回りにねじることで、吸口本体１１を時計回りあるいは反時計回りのいずれかに略９０度回転させ、吸口本体１１の長手方向を移動方向にした掃除が可能である。したがって、壁際に沿って吸口体６を移動させて掃除したり、狭い隙間に吸口体６を挿入したりして掃除することが可能になる。 Such a suction joint 13 is, for example, capable of tilting the extension pipe 5 in the left-right direction (longitudinal direction) in a state where the extension pipe 5 (see FIG. 1) is substantially perpendicular to the floor surface. 4 (grip 4a) is rotated clockwise or counterclockwise to rotate the mouthpiece body 11 approximately 90 degrees clockwise or counterclockwise, and cleaning with the longitudinal direction of the mouthpiece body 11 in the moving direction is performed. Is possible. Therefore, it is possible to clean by moving the mouthpiece 6 along the wall or inserting the mouthpiece 6 into a narrow gap.
図３は、本発明の実施形態に係る吸口体６の下面図である。 FIG. 3 is a bottom view of the mouthpiece 6 according to the embodiment of the present invention.
図３に示すように、吸口体６は、略円筒形状の第１回転清掃体２０、二つの略円筒形状の第２回転清掃体３０を備えている。吸口ケース１０（吸口本体１１）には、下面（清掃面に対峙する面）に、吸込口となる開口部を有する吸込室Ｑ２が形成されている。なお、第１回転清掃体２０や第２回転清掃体の数はこれに限るものではない。 As shown in FIG. 3, the mouthpiece 6 includes a first rotary cleaning body 20 having a substantially cylindrical shape and two second rotary cleaning bodies 30 having a substantially cylindrical shape. In the suction case 10 (suction body 11), a suction chamber Q2 having an opening serving as a suction port is formed on a lower surface (a surface facing the cleaning surface). In addition, the number of the 1st rotation cleaning bodies 20 and the 2nd rotation cleaning bodies is not restricted to this.
第１回転清掃体２０は、吸口本体１１の長手方向（左右方向）に沿って前後方向の連結部１２の前側に配置され、吸口本体１１に回転可能に支持されている。 The first rotary cleaning body 20 is arranged on the front side of the connecting portion 12 in the front-rear direction along the longitudinal direction (left-right direction) of the suction body 11 and is rotatably supported by the suction body 11.
また、第１回転清掃体２０は、線径や密度や硬さが異なる刷毛体や弾性体などの複数種類のブラシ２０ａ、２０ｂ、２０ｃを備え、各ブラシ２０ａ、２０ｂ、２０ｃが回転軸２１（図６参照）に対してらせん状に配設されている。なお、本実施形態例では、３種類のブラシ２０ａ、２０ｂ、２０ｃを配設した場合を例に挙げて説明したが、これに限定されるものではなく、２種類以下であってもよく、４種類以上であってもよく、らせん状に配置されたブラシ間にゴムなどの弾性材料からなるブレード部材をらせん状に配置する構成を追加してもよく、適宜変更することができる。 Moreover, the 1st rotation cleaning body 20 is provided with several types of brushes 20a, 20b, 20c, such as a brush body and an elastic body from which a wire diameter, a density, and hardness differ, and each brush 20a, 20b, 20c is the rotating shaft 21 ( (See FIG. 6). In this embodiment, the case where three types of brushes 20a, 20b, and 20c are provided has been described as an example. However, the present invention is not limited to this and may be two or less types. There may be more types, and a configuration in which a blade member made of an elastic material such as rubber is spirally arranged between spirally arranged brushes may be added and can be changed as appropriate.
第２回転清掃体３０は、第１回転清掃体２０の直径よりも小さな直径の部材である。第２回転清掃体３０は、表面に刷毛体（起毛布）３０ｂを有している。本実施形態では第２回転清掃体３０は二つあり、吸口本体１１において、第１回転清掃体２０の後方で、かつ吸口本体１１の長手方向（第１回転清掃体２０の軸方向）の左右方向にそれぞれ配置されている。換言すると、第２回転清掃体３０は、吸口本体１１において、流路Ｒ（図３参照）を挟んだ両側に設けられている。例えば、一つの第２回転清掃体３０は、第１回転清掃体２０の直径の約二分の一の直径、第１回転清掃体２０の軸方向の長さの略三分の一の長さで構成されており、吸口本体１１において、二つの第２回転清掃体３０を流路Ｒを挟んだ両側に設けることができる。 The second rotary cleaning body 30 is a member having a diameter smaller than the diameter of the first rotary cleaning body 20. The second rotary cleaning body 30 has a brush body (raised cloth) 30b on the surface. In the present embodiment, there are two second rotary cleaning bodies 30, and in the suction body 11, the left and right sides of the longitudinal direction of the suction body 11 (the axial direction of the first rotary cleaning body 20) behind the first rotational cleaning body 20. Are arranged in each direction. In other words, the second rotary cleaning body 30 is provided on both sides of the inlet body 11 with the flow path R (see FIG. 3) interposed therebetween. For example, one second rotary cleaning body 30 has a diameter that is approximately one half of the diameter of the first rotary cleaning body 20 and a length that is approximately one third of the axial length of the first rotary cleaning body 20. In the suction body 11, two second rotary cleaning bodies 30 can be provided on both sides of the flow path R.
また、それぞれの第２回転清掃体３０は、第１回転清掃体２０の回転軸２１と平行なシャフト３０ａを有している。このシャフト３０ａの外周のパイプ体３０ｅ（図６参照）の外側に微細繊維で形成されたカットパイル状の刷毛体（起毛布）３０ｂがパイプ体３０ｅの回転軸方向に対して螺旋状に巻かれており、この刷毛体（起毛布）３０ｂの微細繊維はパイプ体３０ｅに対し円周方向に傾斜している。この刷毛体（起毛布）３０ｂは、吸口体６の一部に接触するように設けられており、吸口体６の後進時に第２回転清掃体３０の回転動作を許容し、かつ前進時に前記第２回転清掃体３０の回転動作を規制するように円周方向に傾斜して設けられている。パイプ体３０ｅの両端面には、ホルダー３０ｃ、３０ｄが固定されている。そして、このホルダー３０ｃ、３０ｄは、巻き付けた刷毛体（起毛布）３０ｂの端部を押さえて剥がれを防止するとともに、シャフト３０ａの軸受けを兼ねている。シャフト３０ａとパイプ体３０ｅは略同心円で隙間を有するので、これによりパイプ体３０ｅおよび刷毛体（起毛布）３０ｂは、シャフト３０ａに回動可能に支持されている。このように、第２回転清掃体３０を電動機で駆動させるのではなく、シャフト３０ａを介して吸口本体１１に支持させ、床面との接触により回転駆動させることにより、第２回転清掃体３０の構成を簡略化することができる。さらに、刷毛体（起毛布）３０ｂの微細繊維は一方向の回転動作を許容し他方向の回転動作を規制するようにパイプ体３０ｅに対し円周方向に傾斜しているため、吸口体６の組み立て時に誤って逆方向に取り付けることのないように、ホルダー３０ｃと３０ｄは、異なる色を用いる、形状を変える、などし、吸口本体１１におけるホルダー３０ｃと３０ｄに対応する部分もそれに応じて色や形状を変えることで、左右の取り付け方向が分かり、誤って取り付けることがないようになっている。 Each second rotary cleaning body 30 has a shaft 30 a parallel to the rotation shaft 21 of the first rotary cleaning body 20. A cut pile-shaped brush body (raised cloth) 30b formed of fine fibers is spirally wound around the rotation axis of the pipe body 30e on the outside of the pipe body 30e (see FIG. 6) on the outer periphery of the shaft 30a. The fine fibers of the brush body (raised cloth) 30b are inclined in the circumferential direction with respect to the pipe body 30e. The brush body (raised cloth) 30b is provided so as to be in contact with a part of the suction body 6, and allows the second rotary cleaning body 30 to rotate when the suction body 6 moves backward, and the first rotation body 30b when moving forward. The two-rotary cleaning body 30 is provided so as to be inclined in the circumferential direction so as to regulate the rotational operation. Holders 30c and 30d are fixed to both end faces of the pipe body 30e. The holders 30c and 30d hold the end of the wound brush body (raised cloth) 30b to prevent peeling, and also serve as a bearing for the shaft 30a. Since the shaft 30a and the pipe body 30e are substantially concentric and have a gap, the pipe body 30e and the brush body (raised cloth) 30b are thereby rotatably supported on the shaft 30a. Thus, instead of driving the second rotary cleaning body 30 with an electric motor, the second rotary cleaning body 30 is supported by the suction body 11 via the shaft 30a and driven to rotate by contact with the floor surface. The configuration can be simplified. Further, since the fine fibers of the brush body (raised cloth) 30b are inclined in the circumferential direction with respect to the pipe body 30e so as to permit the rotation operation in one direction and restrict the rotation operation in the other direction, The holders 30c and 30d use different colors, change their shapes, etc. so that they are not mistakenly attached in the opposite direction during assembly, and the portions corresponding to the holders 30c and 30d in the mouthpiece body 11 also have colors and By changing the shape, the left and right mounting directions can be determined, so that they cannot be installed by mistake.
また、ホルダー３０ｃと３０ｄを含む第２回転清掃体３０の左右幅は、この第２回転清掃体３０を取り付ける収納室の幅Ｌ１より短く構成してある。そのため第２回転清掃体３０は左右に隙間を有しており、この隙間分、シャフト３０ａに沿って左右に移動することができる。このことにより、清掃時に床面の糸屑や髪の毛等の細長い塵埃がシャフト３０ａに巻き付く事を防止することができ、もしシャフト３０ａに巻き付いても、容易に取り除く事が出来る。 The left-right width of the second rotary cleaning body 30 including the holders 30c and 30d is configured to be shorter than the width L1 of the storage chamber to which the second rotary cleaning body 30 is attached. Therefore, the 2nd rotation cleaning body 30 has a clearance gap on either side, and can move to the left and right along the shaft 30a by this clearance gap. Thus, it is possible to prevent slender dust such as lint and hair on the floor from winding around the shaft 30a during cleaning, and even if it is wound around the shaft 30a, it can be easily removed.
なお、吸口ケース１０には、吸口ケース１０の連結部１２の下面にブラシ駆動スイッチ１６が設けられ、ブラシ駆動スイッチ１６の後方（連結部１２の後端）に車輪１７が設けられている。 The suction case 10 is provided with a brush drive switch 16 on the lower surface of the connection portion 12 of the suction case 10, and a wheel 17 is provided behind the brush drive switch 16 (the rear end of the connection portion 12).
ブラシ駆動スイッチ１６は、吸口体６の下面が清掃面に接触しているか否かを検出するスイッチである。ブラシ駆動スイッチ１６は、車輪１６ａを備え、この車輪１６ａがばね等の付勢手段によって常に吸口ケース１０（連結部１２）の下面から突出するように設けられている。そして、車輪１６ａが飛び出して床面と接触していないと検出されたときには、後記する回路基板５０（制御基板）によって電動機４０の駆動が停止される。また、車輪１６ａが押し込まれて床面と接触していると検出されたときには、回路基板５０によって電動機４０が駆動される。 The brush drive switch 16 is a switch that detects whether or not the lower surface of the mouthpiece 6 is in contact with the cleaning surface. The brush drive switch 16 includes a wheel 16a, and the wheel 16a is provided so as to always protrude from the lower surface of the suction case 10 (connecting portion 12) by a biasing means such as a spring. When it is detected that the wheel 16a has popped out and is not in contact with the floor surface, the driving of the electric motor 40 is stopped by a circuit board 50 (control board) described later. Further, when it is detected that the wheel 16 a is pushed in and in contact with the floor surface, the electric motor 40 is driven by the circuit board 50.
車輪１７は、操作管４で操作される前後動や回転操作の応力を受けて吸口体６の底面を清掃面に密着させ、これにより吸口体６の操作性能を向上する役割を有している。 The wheel 17 has a role of improving the operating performance of the mouthpiece 6 by contacting the bottom surface of the mouthpiece 6 with the cleaning surface in response to the stress of the forward and backward movement and rotation operated by the operation tube 4. .
図４は、吸口体６の上ケース１１Ｂを外した状態を示す上面図である。 FIG. 4 is a top view showing a state where the upper case 11B of the mouthpiece 6 is removed.
図４に示すように、吸口体６は、第１回転清掃体２０および一対の第２回転清掃体３０の上方に、第１回転清掃体２０を駆動する電動機４０および電動機４０を制御する回路基板５０を備えている。 As shown in FIG. 4, the suction body 6 includes a motor 40 that drives the first rotary cleaning body 20 and a circuit board that controls the motor 40 above the first rotary cleaning body 20 and the pair of second rotary cleaning bodies 30. 50.
電動機４０は、吸口本体１１の長手方向の一端側に取り付けられている。また、電動機４０は、その出力軸４０ａ（図５参照）が吸口本体１１の長手方向と平行に配置されている。また、電動機４０の出力軸４０ａは、長手方向の一端側に向けて延び、吸口本体１１内の一端部（図示右側の端部）において、歯付きベルト４０ｂを介して第１回転清掃体２０の回転軸２１（図５参照）と連結されている。 The electric motor 40 is attached to one end side of the suction body 11 in the longitudinal direction. Further, the output shaft 40 a (see FIG. 5) of the electric motor 40 is arranged in parallel with the longitudinal direction of the suction mouth body 11. Further, the output shaft 40a of the electric motor 40 extends toward one end side in the longitudinal direction, and at one end portion (the end portion on the right side in the drawing) in the suction body 11 of the first rotary cleaning body 20 via the toothed belt 40b. The rotary shaft 21 (see FIG. 5) is connected.
カバー部材４３は、合成ゴム等の弾力性を有する絶縁部材で形成され、このカバー部材４３の弾力性を利用して収容室Ｑ１に電動機４０の一端側が支持されているので、電動機４０の振動が吸口ケース１０に伝わり難い構造となっている。 The cover member 43 is formed of an insulating member having elasticity such as synthetic rubber. Since the one end side of the electric motor 40 is supported in the storage chamber Q1 by using the elasticity of the cover member 43, the vibration of the electric motor 40 is vibrated. The structure is difficult to be transmitted to the mouthpiece case 10.
回路基板５０は、吸口本体１１の長手方向の他端側に取り付けられている。また、回路基板５０は、長辺が長手方向に向くようにして配置された長方形状の基板で構成され、実装面５０ａが鉛直方向上方を向くように吸口本体１１内に配置されている。なお、実装面５０ａは、必ずしも鉛直方向上方を向くものに限定されず、水平方向に対して傾斜してもよく、前後方向を向くように（縦向きに）してもよい。 The circuit board 50 is attached to the other end side of the suction body 11 in the longitudinal direction. Further, the circuit board 50 is formed of a rectangular board arranged with the long side facing the longitudinal direction, and is arranged in the mouthpiece body 11 so that the mounting surface 50a faces upward in the vertical direction. The mounting surface 50a is not necessarily limited to the one that faces upward in the vertical direction, and may be inclined with respect to the horizontal direction or may be directed in the front-rear direction (vertically).
図５は、図２のＡ−Ａ断面図である。 5 is a cross-sectional view taken along the line AA in FIG.
図５に示すように、吸口ケース１０の吸口本体１１は、第１回転清掃体２０を覆うように下部分を形成する下ケース１１Ａ、および下ケース１１Ａの上部に被着された上ケース１１Ｂを備えている。これら下ケース１１Ａ、上ケース１１Ｂを含む吸口ケース１０および前記した吸口継手１３の主たる部品は、軽量で硬質の材料、例えば、ＡＢＳ樹脂等の合成樹脂材料で形成され、剛性が高められている。 As shown in FIG. 5, the mouthpiece body 11 of the mouthpiece case 10 includes a lower case 11 </ b> A that forms a lower portion so as to cover the first rotary cleaning body 20, and an upper case 11 </ b> B that is attached to the upper portion of the lower case 11 </ b> A. I have. The main parts of the suction case 10 including the lower case 11A and the upper case 11B and the suction joint 13 described above are formed of a light and hard material, for example, a synthetic resin material such as ABS resin, and the rigidity is enhanced.
下ケース１１Ａは、第１回転清掃体２０が配置される吸込室Ｑ２と、電動機４０が収容される収容室Ｑ１とを区画する隔壁１１ｃを有している。隔壁１１ｃは、第１回転清掃体２０の表面に沿って形成される湾曲部１１ｄと、第２回転清掃体３０の表面に沿って形成される湾曲部１１ｅとを有し、湾曲部１１ｄと湾曲部１１ｅとが連続して形成されている。また、湾曲部１１ｄは、断面視において、第１回転清掃体２０の略前端部まで延びている。湾曲部１１ｅは、断面視において、第２回転清掃体３０の後端部よりも後側且つシャフト３０ａよりも後側まで延びている。 The lower case 11A has a partition wall 11c that partitions a suction chamber Q2 in which the first rotary cleaning body 20 is disposed and a storage chamber Q1 in which the electric motor 40 is accommodated. The partition wall 11c includes a curved portion 11d formed along the surface of the first rotary cleaning body 20 and a curved portion 11e formed along the surface of the second rotary cleaning body 30. The curved portion 11d and the curved portion 11c are curved. The part 11e is formed continuously. Further, the curved portion 11d extends to a substantially front end portion of the first rotary cleaning body 20 in a sectional view. The curved portion 11e extends to the rear side of the rear end portion of the second rotary cleaning body 30 and the rear side of the shaft 30a in the cross-sectional view.
上ケース１１Ｂは、連結部１２と一体に形成されて電動機４０および回路基板５０（図４参照）の上部を覆う本体部１１ｆと、この本体部１１ｆの外側に重ねて配置されるカバー部１１ｇとを有している。カバー部１１ｇは、上ケース１１Ｂの前部および左右両端部に渡って配置されている（図２参照）。本実施形態例では、バンパ１１ａが、下ケース１１Ａと上ケース１１Ｂ（カバー部１１ｇ）とで挟み込まれることで保持されている。 The upper case 11B is formed integrally with the connecting portion 12 and covers a main body portion 11f that covers the upper portion of the electric motor 40 and the circuit board 50 (see FIG. 4), and a cover portion 11g that is arranged on the outside of the main body portion 11f. have. The cover portion 11g is disposed over the front portion and the left and right end portions of the upper case 11B (see FIG. 2). In this embodiment, the bumper 11a is held by being sandwiched between the lower case 11A and the upper case 11B (cover portion 11g).
第１回転清掃体２０は、回転軸２１にブラシ２０ａ、２０ｂ、２０ｃを螺旋状に保持するコア部材２２が外嵌されている。このように、ブラシ２０ａ、２０ｂ、２０ｃを螺旋状に配置することにより、第１回転清掃体２０が回転したときに、床面Ｍ（図８参照）にブラシ２０ａ、２０ｂ、２０ｃを連続して当てることができ、第１回転清掃体２０の動作時の振動を抑制することができる。 As for the 1st rotation cleaning body 20, the core member 22 which hold | maintains brush 20a, 20b, 20c helically on the rotating shaft 21 is externally fitted. Thus, by arranging the brushes 20a, 20b, and 20c in a spiral shape, the brushes 20a, 20b, and 20c are continuously provided on the floor M (see FIG. 8) when the first rotary cleaning body 20 rotates. This can be applied, and vibration during operation of the first rotary cleaning body 20 can be suppressed.
第２回転清掃体３０は、シャフト３０ａにパイプ体３０ｅを介して断面が略円形状の刷毛体（起毛布）３０ｂが取り付けられ、吸口本体１１において第１回転清掃体２０と接触しない位置に配置されている。このように、第２回転清掃体３０を第１回転清掃体２０に接触しない範囲において、第１回転清掃体２０と第２回転清掃体３０とを最大限接近させることにより、吸口本体１１の前後幅Ｄ（図２参照）を短くすることが可能になり、吸口体６の小型軽量化が可能となる。 The second rotary cleaning body 30 is arranged at a position where the brush body (raised cloth) 30b having a substantially circular cross section is attached to the shaft 30a via the pipe body 30e and does not contact the first rotary cleaning body 20 in the suction mouth body 11. Has been. As described above, the first rotary cleaning body 20 and the second rotary cleaning body 30 are brought close to each other within the range in which the second rotary cleaning body 30 does not come into contact with the first rotary cleaning body 20. The width D (see FIG. 2) can be shortened, and the mouthpiece 6 can be reduced in size and weight.
電動機４０のステータ４１は、横断面（出力軸４０ａに直交する断面の輪郭、輪切り断面）が略小判形状を呈している。ステータ４１は、一対の円弧部４１ａと、これらの円弧部４１ａをつなぐ一対の直線部４１ｂとを備えている。なお、電動機４０は、略小判形状のものに限定されるものではなく、円形状のものであってもよい。 The stator 41 of the electric motor 40 has a substantially oval cross section (outline of cross section orthogonal to the output shaft 40a, round cross section). The stator 41 includes a pair of arc portions 41a and a pair of linear portions 41b that connect these arc portions 41a. The electric motor 40 is not limited to a substantially oval shape, and may be a circular shape.
また、電動機４０は、収容室Ｑ１において、直線部４１ｂが鉛直方向の軸Ｚ１に対して傾斜した姿勢、つまり一方の円弧部４１ａが前方上向き且つ他方の円弧部４１ａが後方下向きとなるように収容されている。 In addition, the electric motor 40 is accommodated in the accommodation chamber Q1 such that the linear portion 41b is inclined with respect to the vertical axis Z1, that is, one arc portion 41a faces upward and the other arc portion 41a faces backward and downward. Has been.
また、電動機４０は、収容室Ｑ１において、電動機４０（ステータ４１）の前端部４１ｓが、第１回転清掃体２０の後端部２０ｓよりも前方に位置するように配置されている。これにより、第１回転清掃体２０の後端部２０ｓから後方に突出する電動機４０の距離を短くでき、吸口本体１１の前後幅Ｄ（図２参照）を短くすることが可能になる。 Moreover, the electric motor 40 is arrange | positioned so that the front-end part 41s of the electric motor 40 (stator 41) may be located ahead of the rear-end part 20s of the 1st rotation cleaning body 20 in the storage chamber Q1. Thereby, the distance of the electric motor 40 which protrudes back from the rear-end part 20s of the 1st rotation cleaning body 20 can be shortened, and it becomes possible to shorten the front-back width D (refer FIG. 2) of the suction inlet main body 11. FIG.
また、電動機４０は、収容室Ｑ１において、電動機４０（ステータ４１）の下端部４１ｔが、第１回転清掃体２０の上端部２０ｔよりも鉛直方向の下方に位置するように配置されている。これにより、第１回転清掃体２０の上端部２０ｔから上方に突出する電動機４０の距離を短くでき、吸口本体１１の清掃面から高さ（最大高さ）を低くすることができる。その結果、ソファやベッドなどの高さの低い隙間に吸口本体１１を挿入し易くできる。 Moreover, the electric motor 40 is arrange | positioned so that the lower end part 41t of the electric motor 40 (stator 41) may be located in the downward direction of the perpendicular direction rather than the upper end part 20t of the 1st rotation cleaning body 20 in the storage chamber Q1. Thereby, the distance of the electric motor 40 which protrudes upward from the upper end part 20t of the 1st rotation cleaning body 20 can be shortened, and height (maximum height) can be made low from the cleaning surface of the suction inlet main body 11. FIG. As a result, the mouthpiece body 11 can be easily inserted into a low gap such as a sofa or a bed.
ステータ４１の内部には、アーマチュア４４が回転自在に支持されている。ステータ４１の内周には、界磁用の瓦状に形成された２つのマグネット４５が周方向に間隔を隔てて固着されている。すなわち、本実施形態例の電動機４０は、スロットの個数が７個、マグネット４５が２つ設けられた２極７スロットのモータである。なお、前記したスロットの数は、７個に限られることはなく他の個数（例えば８個）に設定してもよい。 An armature 44 is rotatably supported inside the stator 41. On the inner periphery of the stator 41, two magnets 45 formed in a field tile shape are fixed with a gap in the circumferential direction. That is, the electric motor 40 of the present embodiment is a two-pole seven-slot motor provided with seven slots and two magnets 45. The number of slots described above is not limited to seven, and may be set to another number (for example, eight).
また、吸口本体１１の上ケース１１Ｂは、円弧部４１ａの近傍および直線部４１ｂの近傍において、円弧部４１ａおよび直線部４１ｂに略沿う形状を有している。また、吸口本体１１の下ケース１１Ａは、第１回転清掃体２０の後方において、下ケース１１Ａおよび上ケース１１Ｂによって構成される収容室Ｑ１から下方に湾曲して延びる外郭壁１１ｈを有している。この外郭壁１１ｈは、第２回転清掃体３０の曲面（表面）に沿って延び、外郭壁１１ｈの下端部１１ｈ１が、第２回転清掃体３０のシャフト３０ａの略高さ位置まで下降するように延びている。 Further, the upper case 11B of the mouthpiece main body 11 has a shape substantially along the arc portion 41a and the straight portion 41b in the vicinity of the arc portion 41a and the vicinity of the straight portion 41b. Further, the lower case 11A of the suction body 11 has an outer wall 11h that curves downward and extends downward from the housing chamber Q1 constituted by the lower case 11A and the upper case 11B, behind the first rotary cleaning body 20. . The outer wall 11h extends along the curved surface (surface) of the second rotary cleaning body 30, and the lower end portion 11h1 of the outer wall 11h is lowered to a substantially height position of the shaft 30a of the second rotary cleaning body 30. It extends.
図６は、図２のＢ−Ｂ断面図である。 6 is a cross-sectional view taken along line BB in FIG.
図６に示すように、回路基板５０は、収容室Ｑ１において、実装面が鉛直方向（上下方向）上向きとなるように配置されている。すなわち、回路基板５０は、第１回転清掃体２０の後方ではなく、第１回転清掃体２０の上端部２０ｔよりも上側に配置されている。なお、回路基板５０は、図示しない位置決め手段やねじ固定によって、位置ずれしないように吸口本体１１内に固定されている。また、本実施形態例では、回路基板５０を水平に配置した場合を例に挙げて説明したが、回路基板５０を水平方向に対して傾斜した状態で配置する構成であってもよく、回路基板５０の実装面が前後方向を向くように、回路基板５０を起立した状態で配置してもよい。 As shown in FIG. 6, the circuit board 50 is disposed in the accommodation chamber Q <b> 1 so that the mounting surface faces upward in the vertical direction (vertical direction). That is, the circuit board 50 is arranged not on the rear side of the first rotary cleaning body 20 but on the upper side of the upper end portion 20t of the first rotary cleaning body 20. The circuit board 50 is fixed in the mouthpiece body 11 so as not to be displaced by positioning means (not shown) or screw fixing. Further, in the present embodiment example, the case where the circuit board 50 is horizontally arranged has been described as an example. However, the circuit board 50 may be arranged in an inclined state with respect to the horizontal direction. The circuit board 50 may be placed upright so that the mounting surface 50 faces in the front-rear direction.
第２回転清掃体３０は、パイプ体３０ｅの外側に微細繊維で形成されたカットパイル状の刷毛体（起毛布）３０ｂが螺旋状に巻かれており、この刷毛体（起毛布）３０ｂの微細繊維はパイプ体３０ｅに対し円周方向に傾斜している。パイプ体３０ｅの両端面には、ホルダー３０ｃ、３０ｄが固定されている。そして、このホルダー３０ｃ、３０ｄは、巻き付けた起毛布３０ｂの端部の剥がれ防止と、シャフト３０ａの軸受けを兼ねている。この起毛布３０ｂの先端は、隔壁湾曲部１１ｅの表面に接触する様な刷毛高さを有している。このため、第２回転清掃体３０が回転する際、刷毛体（起毛布）３０ｂと隔壁湾曲部１１ｅの表面との間で、摩擦抵抗が発生するが、微細繊維がパイプ体３０ｅに対し円周方向に傾斜しているため、回転方向Ｗ２には、摩擦抵抗が小さく自由に回転するが、回転方向Ｗ３には、摩擦抵抗が大きくほぼロック状態となる。つまり、刷毛体（起毛布）３０ｂは、隔壁湾曲部１１ｅに接触するように設けられており、吸口体６の後進時に第２回転清掃体３０の回転方向Ｗ２への回転動作を許容し、かつ前進時に前記第２回転清掃体３０の回転方向Ｗ３への回転動作を規制するように円周方向に傾斜して設けられている。 In the second rotary cleaning body 30, a cut pile-like brush body (brushed cloth) 30b formed of fine fibers is wound on the outside of the pipe body 30e in a spiral shape, and the brush body (raised cloth) 30b is finely wound. The fibers are inclined in the circumferential direction with respect to the pipe body 30e. Holders 30c and 30d are fixed to both end faces of the pipe body 30e. And these holders 30c and 30d serve as both the prevention of peeling of the edge part of the wound raising cloth 30b, and the bearing of the shaft 30a. The tip of the brushed fabric 30b has a brush height that contacts the surface of the partition curved portion 11e. For this reason, when the second rotary cleaning body 30 rotates, a frictional resistance is generated between the brush body (raised cloth) 30b and the surface of the partition curved portion 11e, but the fine fibers are circumferential with respect to the pipe body 30e. Since it is inclined in the direction, the frictional resistance is small and rotates freely in the rotational direction W2, but the frictional resistance is large in the rotational direction W3 and is almost locked. That is, the brush body (raised cloth) 30b is provided so as to be in contact with the partition curved portion 11e, and allows the second rotary cleaning body 30 to rotate in the rotational direction W2 when the suction body 6 moves backward, and It is provided so as to be inclined in the circumferential direction so as to restrict the rotational movement of the second rotary cleaning body 30 in the rotational direction W3 during forward movement.
また、シャフト３０ａの全周方向に刷毛体（起毛布）３０ｂを均等に巻き付けているため、吸込室Ｑ２の気密を保持しやすく、また吸込室Ｑ２から漏れる騒音や隙間を流れる気流により発生する騒音を小さくできる。 Further, since the brush body (raised cloth) 30b is evenly wound around the entire circumference of the shaft 30a, it is easy to maintain the airtightness of the suction chamber Q2, and noise generated by the air leaking from the suction chamber Q2 and the airflow flowing through the gaps. Can be reduced.
また第２回転清掃体３０は、図３に示すように、左右に隙間を有しているが、吸口体６が床面Ｍに接触して清掃している時は、吸引により中央部に吸い寄せられ、流速の速い中央側の隙間を塞ぐように移動するので、漏れ騒音を抑制できる。 Further, as shown in FIG. 3, the second rotary cleaning body 30 has a gap on the left and right sides, but when the suction body 6 is in contact with the floor surface M for cleaning, the second rotary cleaning body 30 is sucked to the center by suction. Since it moves so as to close the gap on the central side where the flow velocity is fast, leakage noise can be suppressed.
図７は、本発明の実施形態に係る吸口体を床面から離した状態の側面図である。 FIG. 7 is a side view showing a state where the mouthpiece according to the embodiment of the present invention is separated from the floor surface.
図７に示すように、吸口体６が床面Ｍに接触していない場合には、第１回転清掃体２０の下端部２０ｕが、第２回転清掃体３０の下端部３０ｕよりも鉛直方向の下方に位置している。また、連結部１２の下面に設けられた車輪１６ａが突出して、ブラシ駆動スイッチ１６がオフになり、第１回転清掃体２０の動作が停止する。 As shown in FIG. 7, when the suction body 6 is not in contact with the floor surface M, the lower end 20 u of the first rotary cleaning body 20 is more vertically oriented than the lower end 30 u of the second rotary cleaning body 30. Located below. Moreover, the wheel 16a provided in the lower surface of the connection part 12 protrudes, the brush drive switch 16 is turned off, and the operation | movement of the 1st rotary cleaning body 20 stops.
図８は、本発明の実施形態に係る吸口体が床面に接している状態の側面図である。 FIG. 8 is a side view of the mouthpiece according to the embodiment of the present invention in contact with the floor surface.
図８に示すように、吸口体６が床面Ｍに接触すると、車輪１６ａが押し込まれ、ブラシ駆動スイッチ１６がオンになり、第１回転清掃体２０がＷ１方向（図示反時計回り方向）に回転する。このとき、床面Ｍと接触する領域のブラシ２０ａ、２０ｂ、２０ｃが撓むことで、ブラシ２０ａ、２０ｂ、２０ｃと床面Ｍとの接触量を十分に確保することができ、床面Ｍの塵埃を効果的に掻き込むことができる。 As shown in FIG. 8, when the suction body 6 contacts the floor M, the wheel 16a is pushed in, the brush drive switch 16 is turned on, and the first rotary cleaning body 20 is in the W1 direction (counterclockwise direction in the figure). Rotate. At this time, since the brushes 20a, 20b, and 20c in the region in contact with the floor surface M are bent, a sufficient amount of contact between the brushes 20a, 20b, and 20c and the floor surface M can be secured. Dust can be scraped effectively.
同様に、第２回転清掃体３０が床面Ｍと接触することにより、床面Ｍと接触する領域の刷毛体（起毛布）３０ｂが撓むことで、刷毛体（起毛布）３０ｂと床面Ｍとの接触抵抗を十分に確保することができる。 Similarly, when the second rotary cleaning body 30 is in contact with the floor surface M, the brush body (raised cloth) 30b in the region in contact with the floor surface M is bent, so that the brush body (raised cloth) 30b and the floor surface are bent. A sufficient contact resistance with M can be secured.
図９は、本発明の実施形態に係る吸口体６が後退している状態の側面図である。 FIG. 9 is a side view of the state in which the mouthpiece 6 according to the embodiment of the present invention is retracted.
図９に示すように、第２回転清掃体３０は、刷毛体（起毛布）３０ｂと床面Ｍとの接触抵抗より刷毛体（起毛布）３０ｂと隔壁湾曲部１１ｅとの接触抵抗が小さいため、Ｗ３で示す回転方向に回転し、床上の塵埃ＤＳを吸込室Ｑ２内に導入する。導入された塵埃ＤＳは、吸込室Ｑ２（図６参照）から流路Ｒ（図３参照）を通じて吸口継手１３の通路に運ばれ、その後、延長管５、操作管４およびホース部３を通じて掃除機本体２の集塵部２ｂに吸引される（図１参照）。集塵部２ｂによって塵埃が取り除かれた空気は、図示しないフィルタおよび電動送風機２ａ内を通り、掃除機本体２の外部に排出される（図１参照）。 As shown in FIG. 9, the second rotary cleaning body 30 has a smaller contact resistance between the brush body (raised cloth) 30b and the partition curved portion 11e than the contact resistance between the brush body (raised cloth) 30b and the floor surface M. , W3, and the dust DS on the floor is introduced into the suction chamber Q2. The introduced dust DS is carried from the suction chamber Q2 (see FIG. 6) to the passage of the suction joint 13 through the flow path R (see FIG. 3), and then through the extension pipe 5, the operation pipe 4 and the hose portion 3 to the vacuum cleaner. It is sucked into the dust collecting part 2b of the main body 2 (see FIG. 1). The air from which the dust has been removed by the dust collecting portion 2b passes through a filter (not shown) and the electric blower 2a and is discharged to the outside of the cleaner body 2 (see FIG. 1).
図１０は、本発明の実施形態に係る吸口体６が前進している状態の側面図である。 FIG. 10 is a side view of the state in which the mouthpiece 6 according to the embodiment of the present invention is moving forward.
図１０に示すように、第２回転清掃体３０は、刷毛体（起毛布）３０ｂと床面Ｍとの接触抵抗より刷毛体（起毛布）３０ｂと隔壁湾曲部１１ｅとの接触抵抗が大きいため回転せず、吸込室Ｑ２内に吸引された塵埃が吸口本体１１の後方に掃き出されるのを防止することができる。とくに第１回転清掃体２０の回転によって吸込室Ｑ２内に吸引された塵埃が後方へ弾かれ、吸口本体１１の後方に飛び出ることを抑制できる。 As shown in FIG. 10, in the second rotary cleaning body 30, the contact resistance between the brush body (raised cloth) 30b and the partition curved portion 11e is larger than the contact resistance between the brush body (raised cloth) 30b and the floor surface M. The dust sucked into the suction chamber Q2 without rotating can be prevented from being swept out to the rear of the suction body 11. In particular, the dust sucked into the suction chamber Q <b> 2 by the rotation of the first rotary cleaning body 20 can be prevented from being flipped rearward and jumping out to the rear of the suction body 11.
吸引された塵埃ＤＳは、吸込室Ｑ２（図６参照）から流路Ｒ（図３参照）を通じて吸口継手１３の通路に運ばれ、その後、延長管５、操作管４およびホース部３を通じて掃除機本体２の集塵部２ｂに吸引される（図１参照）。集塵部２ｂによって塵埃が取り除かれた空気は、図示しないフィルタおよび電動送風機２ａ内を通り、掃除機本体２の外部に排出される（図１参照）。 The sucked dust DS is carried from the suction chamber Q2 (see FIG. 6) to the passage of the suction joint 13 through the flow path R (see FIG. 3), and then through the extension pipe 5, the operation pipe 4 and the hose portion 3 to the vacuum cleaner. It is sucked into the dust collecting part 2b of the main body 2 (see FIG. 1). The air from which the dust has been removed by the dust collecting portion 2b passes through a filter (not shown) and the electric blower 2a and is discharged to the outside of the cleaner body 2 (see FIG. 1).
このように、本実施形態例によれば、第１回転清掃体の後方に床面Ｍと接する第２回転清掃体３０を設けたことにより、吸口体６を後退させたときに（吸口体６を後方に引いたときに）、第２回転清掃体３０が床面Ｍとの接触抵抗により回転することで、吸口本体１１の後方の塵埃を吸込室Ｑ２内に吸い込むことができる。 As described above, according to the present embodiment, the second rotary cleaning body 30 in contact with the floor surface M is provided behind the first rotary cleaning body, so that the suction body 6 is retracted (the suction body 6 When the second rotary cleaning body 30 is rotated by contact resistance with the floor surface M, dust behind the suction port body 11 can be sucked into the suction chamber Q2.
また、吸口体６を前進させたときに（吸口体６を前方へ押したときに）、第２回転清掃体３０の回転が規制されるため、第１回転清掃体２０によって吸込室Ｑ２内に掻き込まれた塵埃が、吸口本体１１の後方に掃き出されるのを防止することができる。 Further, when the suction body 6 is moved forward (when the suction body 6 is pushed forward), the rotation of the second rotary cleaning body 30 is restricted, so that the first rotary cleaning body 20 causes the suction chamber Q2 to enter the suction chamber Q2. It is possible to prevent the dust that has been scraped out from being swept out to the rear of the mouthpiece body 11.
また、本実施形態例によれば、第２回転清掃体３０の回転方向を規制する手段として可動部を設ける必要がないので、構造が簡単になる。また、砂ゴミ等の侵入により、規制機能が損なわれる恐れも小さい。 Further, according to the present embodiment example, it is not necessary to provide a movable part as a means for regulating the rotation direction of the second rotary cleaning body 30, so that the structure is simplified. In addition, there is little possibility that the regulation function is impaired by the intrusion of sand dust or the like.
また、本実施形態例では、第２回転清掃体３０の刷毛体（起毛布）３０ｂの先端は、隔壁湾曲部１１ｅの表面全体に接する様な刷毛高さを有していたが、必ずしも隔壁湾曲部１１ｅの表面全体に接する必要ななく、例えば図１１に示すように、隔壁湾曲部１１ｅの内側に断面形状が略三角形状の突起３５ａ、３５ｂ、３５ｃを設け、これらの突起と刷毛体（起毛布）３０ｂの先端が接触する様に刷毛高さを設定することにより、回転方向Ｗ２には、摩擦抵抗が小さくほぼ自由に回転するが、回転方向Ｗ３には、摩擦抵抗が大きくほぼロック状態となる。 In this embodiment, the tip of the brush body (raised cloth) 30b of the second rotary cleaning body 30 has a brush height that touches the entire surface of the partition curved portion 11e. For example, as shown in FIG. 11, projections 35a, 35b, and 35c having a substantially triangular cross-section are provided on the inner side of the partition curved portion 11e. (Blanket) By setting the brush height so that the tip of 30b is in contact, the frictional resistance is small in the rotational direction W2 and the roller rotates almost freely. Become.
さらに詳しく説明すると、第２回転清掃体３０の回転駆動力は、刷毛体（起毛布）３０ｂと床面Ｍとの摩擦力であり、第２回転清掃体３０の回転制動力は、刷毛体（起毛布）３０ｂと突起３５ａ、３５ｂ、３５ｃとの摩擦力である。起毛布３０ｂの微細繊維はパイプ体３０ｅに対し円周方向に傾斜しており、その傾斜の方向は、刷毛体（起毛布）３０ｂが床面に接する位置にて、吸口体６の前方から後方向きである。このため、吸口体６を前進させる時は、起毛布３０ｂと床面Ｍとの摩擦力すなわち第２回転清掃体３０の回転駆動力は小さくなり、刷毛体（起毛布）３０ｂと突起３５ａ、３５ｂ、３５ｃとの摩擦力すなわち第２回転清掃体３０の回転制動力は大きくなり、第２回転清掃体３０の回転は規制される。逆に吸口体６を後退させる時は、刷毛体（起毛布）３０ｂと床面Ｍとの摩擦力すなわち第２回転清掃体３０の回転駆動力は大きくなり、刷毛体（起毛布）３０ｂと突起３５ａ、３５ｂ、３５ｃとの摩擦力すなわち第２回転清掃体３０の回転制動力は小さくなり、第２回転清掃体３０は回転する。 More specifically, the rotational driving force of the second rotary cleaning body 30 is a frictional force between the brush body (raised cloth) 30b and the floor M, and the rotational braking force of the second rotary cleaning body 30 is the brush body ( It is the frictional force between the raised fabric 30b and the projections 35a, 35b, 35c. The fine fibers of the raised cloth 30b are inclined in the circumferential direction with respect to the pipe body 30e, and the direction of the inclination is the position where the brush body (raised cloth) 30b is in contact with the floor surface from the front to the rear of the mouthpiece 6. The direction. For this reason, when the suction body 6 is advanced, the frictional force between the raised cloth 30b and the floor surface M, that is, the rotational driving force of the second rotary cleaning body 30, is reduced, and the brush body (raised cloth) 30b and the protrusions 35a and 35b. , 35c, that is, the rotational braking force of the second rotary cleaning body 30 is increased, and the rotation of the second rotary cleaning body 30 is restricted. Conversely, when the suction body 6 is moved backward, the frictional force between the brush body (raised cloth) 30b and the floor surface M, that is, the rotational driving force of the second rotary cleaning body 30 increases, and the brush body (raised cloth) 30b and the protrusion The frictional force with 35a, 35b, 35c, that is, the rotational braking force of the second rotary cleaning body 30 is reduced, and the second rotary cleaning body 30 rotates.
なお、本実施形態例では、第２回転清掃体３０の回転方向Ｗ３時には、ほぼロック状態となると述べたが、必ずしもロックする必要はなく、吸口体６が前進している状態で第２回転清掃体３０の回転が、フリーの時と比較して遅くなれば、第１回転清掃体２０によって吸込室Ｑ２内に掻き込まれた塵埃が吸口本体１１の後方に掃き出されるのを防止することができる。 In the present embodiment example, it is described that the second rotary cleaning body 30 is substantially locked when the rotation direction W3 of the second rotary cleaning body 30; however, it is not always necessary to lock the second rotary cleaning body 30 while the suction body 6 is moving forward. If the rotation of the body 30 becomes slower than when it is free, the dust swept into the suction chamber Q2 by the first rotary cleaning body 20 can be prevented from being swept out to the rear of the mouthpiece body 11. it can.
なお、本実施形態例では、第２回転清掃体３０の表面に刷毛体（起毛布）３０ｂを設け、刷毛体（起毛布）３０ｂが、吸口体６の一部と接触するように設けられており、吸口体６の後退時に回転動作を許容し、かつ前進時に回転動作を規制するように円周方向に傾斜して設けたとしたが、この限りではない。簡単な構成で、回転の際、一方向の回転を規制し、他方向の回転を許容する効果を奏する部材、取付け方であれば良い。例えば、本実施形態の刷毛体（起毛布）３０ｂを弾性体とすることでも上記効果を奏すると考えられる。 In this embodiment, a brush body (raised cloth) 30 b is provided on the surface of the second rotary cleaning body 30, and the brush body (raised cloth) 30 b is provided so as to be in contact with a part of the mouthpiece 6. In this case, the suction body 6 is provided so as to be inclined in the circumferential direction so as to permit the rotation operation when the suction body 6 is retracted and to restrict the rotation operation when the suction body 6 moves forward. A simple structure may be used as long as it is a member and an attachment method that have the effect of restricting rotation in one direction and allowing rotation in the other direction during rotation. For example, it is considered that the above effect can be obtained by using the brush body (raised cloth) 30b of the present embodiment as an elastic body.
以上述べたように本形態例によれば、簡単な構成で、前進時には第２回転清掃体３０がほぼ固定して床面と接触するので、前方から吸い込んだ塵埃を第２回転清掃体３０より後方へ排出しにくくすることが可能で、かつ、後退時には第２回転清掃体３０が回転して吸口体６の後方の塵埃を吸込室Ｑ２へ搬送することができ、塵埃の吸い残しを抑制できる。また、本実施形態例では、第１回転清掃体と、これを回転駆動する電動機を用いる場合を説明したが、掃除機本体２の電動送風機２ａによって発生する吸引力を用いて第１回転清掃体を駆動して、また第１回転清掃体がなくても同様の効果が得られる。
As described above, according to the present embodiment, since the second rotary cleaning body 30 is substantially fixed and comes into contact with the floor surface when moving forward, the dust sucked from the front side is collected from the second rotary cleaning body 30 with a simple configuration. It is possible to make it difficult to discharge to the rear, and when retreating, the second rotary cleaning body 30 can be rotated to transport the dust behind the suction body 6 to the suction chamber Q2, and the remaining dust can be suppressed. . Moreover, although the case where the 1st rotation cleaning body and the electric motor which rotationally drives this were used was demonstrated in this embodiment, the 1st rotation cleaning body is used using the suction | attraction force which generate | occur | produces with the electric blower 2a of the cleaner body 2. The same effect can be obtained without driving the first rotating cleaning body.
