Reference 1).

特開2005−329009号公報JP 2005-329209 A

従来の電気掃除機用アタッチメントは、吸込口の周囲がブラシで囲まれている。このような電気掃除機用アタッチメントで平坦な被掃除面を掃くと、ブラシが掻き上げた塵埃が吸込口に円滑に吸い込まれない場合があった。例えば、従来の電気掃除機用アタッチメントは、平坦な被掃除面にブラシを押し当てると、枠体およびブラシが適宜に傾動し、ブラシの毛先の全てが略一様に被掃除面に当接される。この状態で従来の電気掃除機用アタッチメントを移動させると、ブラシに掃かれた塵埃が吸込口側に円滑に移動せず、吸込口から遠ざかる方向へ掃き出されてしまうことがあった。   In the conventional attachment for a vacuum cleaner, the periphery of the suction port is surrounded by a brush. When a flat surface to be cleaned is swept with such an attachment for an electric vacuum cleaner, the dust picked up by the brush may not be smoothly sucked into the suction port. For example, in a conventional attachment for a vacuum cleaner, when the brush is pressed against a flat surface to be cleaned, the frame and the brush are appropriately tilted, and all of the brush tips contact the surface to be cleaned substantially uniformly. Is done. When the conventional vacuum cleaner attachment is moved in this state, the dust swept by the brush may not be smoothly moved to the suction port side, and may be swept away from the suction port.

一方、吸込口の周囲の一部がブラシで囲まれた従来の電気掃除機用アタッチメント、例えば吸込口の周囲がブラシでコ字状に囲まれた従来の電気掃除機用アタッチメントは、ブラシが掻き上げた塵埃を吸込口の前方(吸込口に吸い込まれる空気流の反対方向)に掃き集めるには好都合であるが、吸込口周囲の流路断面積が大きく、吸い込まれる空気の流速が下がってしまうため、掃き集めた塵埃を吸い込む力が劣ってしまう。   On the other hand, a conventional vacuum cleaner attachment in which a part of the periphery of the suction port is surrounded by a brush, for example, a conventional attachment for a vacuum cleaner in which the periphery of the suction port is surrounded by a U-shape is brushed. It is convenient for sweeping up the dust in front of the suction port (opposite direction of the air flow sucked into the suction port), but the flow passage cross-sectional area around the suction port is large, and the flow velocity of the sucked air decreases. For this reason, the power to suck in the dust collected is inferior.

すなわち、ブラシの毛先の全てが略一様に被掃除面を掃くような能動的な姿勢調整が行われる枠体およびブラシを備えた従来の電気掃除機用アタッチメントは、被掃除面における塵埃の掃き集め易さと、掃き集めた塵埃を吸い込む力とを両立させることが困難であった。   That is, the conventional attachment for a vacuum cleaner provided with a frame and a brush that are actively adjusted in posture so that all of the brush tips sweep the surface to be cleaned substantially uniformly. It has been difficult to achieve both ease of sweeping and the ability to suck in dust that has been swept up.

本発明は、被掃除面における塵埃の掃き集め易さと、掃き集めた塵埃を吸い込む力とを両立可能な電気掃除機用アタッチメント、吸込口体および電気掃除機を提案する。   The present invention proposes an attachment for a vacuum cleaner, a suction port, and a vacuum cleaner that can achieve both the ease of dust collection on the surface to be cleaned and the force to suck in the dust collected.

A pair of brushes that divide and surround each of the part side and the latter part side by approximately half a circumference, and the latter part side of the brush is implanted so that the tip of the brush on the latter part side substantially uniformly contacts the surface to be cleaned. And a rear half frame body pivotally supported at one end of the connecting pipe portion so as to be in contact with each other.

また、本発明に係る吸込口体は、吸込口を有する本体部と、前記本体部に設けられた接続管部と、前記接続管部に嵌脱自在に嵌め込まれた前記電気掃除機用アタッチメントと、を備えたことを特徴とする。   Further, a suction port body according to the present invention includes a main body portion having a suction port, a connection pipe portion provided in the main body portion, and the attachment for the vacuum cleaner that is detachably fitted in the connection pipe portion. , Provided.

さらに、本発明に係る電気掃除機は、掃除機本体と、前記掃除機本体に連通された集塵ホースと、前記集塵ホースに連通された延長管と、前記延長管の端部に嵌脱自在に嵌め込まれた前記電気掃除機用アタッチメントと、を備えたことを特徴とする。   Furthermore, the vacuum cleaner according to the present invention includes a vacuum cleaner body, a dust collection hose communicated with the vacuum cleaner body, an extension pipe communicated with the dust collection hose, and an end of the extension pipe. And an attachment for the electric vacuum cleaner fitted freely.

電気掃除機1は、操作部6の起動スイッチ26が操作されると、電動送風機12が運転を開始し、塵埃分離集塵部14に負圧が作用する。この負圧は掃除機本体2の接続口2aから集塵ホース3と手元操作管4と延長管7とを経て吸込口体8に作用する。そうすると、電気掃除機1は吸込口体8から床などの被掃除面に溜まった塵埃を空気とともに吸い込んで被掃除面を掃除する。吸込口体8に吸い込まれた含塵空気は、掃除機本体2に収容された塵埃分離集塵部14によって空気と塵埃とに分離される。分離された塵埃は塵埃分離集塵部14に集塵される。他方、分離された空気は、電動送風機12を通って排気口から掃除機本体2の外部へ吐出される。   In the vacuum cleaner 1, when the start switch 26 of the operation unit 6 is operated, the electric blower 12 starts operation, and negative pressure acts on the dust separation and collection unit 14. The negative pressure acts on the suction port body 8 from the connection port 2a of the cleaner body 2 through the dust collecting hose 3, the hand operation tube 4, and the extension tube 7. If it does so, the vacuum cleaner 1 will inhale the dust collected on the to-be-cleaned surfaces, such as a floor, from the suction inlet body 8 with air, and will clean the to-be-cleaned surface. The dust-containing air sucked into the suction port body 8 is separated into air and dust by the dust separating and collecting part 14 accommodated in the cleaner body 2. The separated dust is collected in the dust separation and collection unit 14. On the other hand, the separated air passes through the electric blower 12 and is discharged from the exhaust port to the outside of the cleaner body 2.

また、連結管部31の端部31bに一体的に設けられたケーシング32は、その内部に延長管7と吸込口体8とを電気的に接続させるコネクタ(図示省略)および給電線(図示省略)と、アタッチメント28を吸込口体8の係止機構に着脱自在に係止させる係止凹部49と、を備える。   Further, the casing 32 integrally provided at the end 31b of the connecting pipe part 31 has a connector (not shown) and a power supply line (not shown) for electrically connecting the extension pipe 7 and the suction port body 8 therein. And a locking recess 49 that detachably locks the attachment 28 to the locking mechanism of the suction port body 8.

一対のブラシ35は、略直線状に延在された毛を複数束ねた毛束35aを第一枠体33および第二枠体34に複数並設させて構成される。また、一対のブラシ35は、第一枠体33および第二枠体34を適宜に傾動させ、毛束35aの伸びる方向を略平行に揃えた状態で、その毛先が略同一面(図4中、二点鎖線)に揃えられる。   The pair of brushes 35 is configured by arranging a plurality of hair bundles 35 a obtained by bundling a plurality of bristles extending substantially linearly on the first frame body 33 and the second frame body 34. In addition, the pair of brushes 35 has the bristles substantially flush with each other with the first frame 33 and the second frame 34 tilted appropriately so that the direction in which the hair bundle 35a extends is substantially parallel (FIG. 4). Middle, two-dot chain line).

そして、第一枠体33に植設された第一ブラシ36は、第二枠体34に植設された第二ブラシ37よりも低い剛性を有するよう構成される。例えば、第一ブラシ36および第二ブラシ37は、同じ材質と略同じ線径とを有するとともに、第二ブラシ37よりも第一ブラシ36のほうが長い毛足を有するよう形成される。   The first brush 36 implanted in the first frame 33 is configured to have lower rigidity than the second brush 37 implanted in the second frame 34. For example, the first brush 36 and the second brush 37 are formed so as to have the same material and substantially the same wire diameter, and the first brush 36 has a longer bristle leg than the second brush 37.

第一枠体33は、連結管部31の軸孔48に枢支された軸部51aを備える。   The first frame 33 includes a shaft portion 51 a that is pivotally supported by the shaft hole 48 of the connecting pipe portion 31.

第二枠体34は、その内側に曲面52aを有するガイド凹部52が形成される。ガイド凹部52は、第二枠体34を傾動させケーシング32に当接させたとき、曲面52aが連結管部31の開口44の縁部31cに略連続的に繋がるよう形成される。   The second frame 34 is formed with a guide recess 52 having a curved surface 52a on the inside thereof. The guide recess 52 is formed so that the curved surface 52 a is connected substantially continuously to the edge 31 c of the opening 44 of the connecting pipe portion 31 when the second frame 34 is tilted and brought into contact with the casing 32.

図5は、本発明の実施形態に係るアタッチメントの吸込口体側の端部を示した部分的な断面図である。   FIG. 5 is a partial cross-sectional view showing an end of the attachment according to the embodiment of the present invention on the suction port body side.

図6は、本発明の実施形態に係るアタッチメントの第一枠体および第二枠体を示した斜視図である。   FIG. 6 is a perspective view showing a first frame and a second frame of the attachment according to the embodiment of the present invention.

図5および図6に示すように、アタッチメント28の第一枠体33および第二枠体34は、それぞれ略コ字状に形成され、それぞれの開放端を付き合わせると全体で環状となる枠本体33a、34aを備える。また、第一枠体33および第二枠体34は、それぞれの枠本体33a、34aの開放端部に、連結管部31に対して互いを独立させて傾動自在に軸支させるとともに、互いを相対的に傾動自在に枢支する一対のヒンジ機構51を備える。   As shown in FIGS. 5 and 6, the first frame 33 and the second frame 34 of the attachment 28 are each formed in a substantially U-shape, and a frame main body that is annular as a whole when the respective open ends are attached to each other. 33a and 34a are provided. Further, the first frame body 33 and the second frame body 34 are pivotally supported at the open ends of the respective frame main bodies 33a and 34a so as to be independent from each other with respect to the connecting pipe portion 31, and to each other. A pair of hinge mechanisms 51 that are pivotably supported relatively is provided.

一対のヒンジ機構51は、同一線上に位置された傾動軸芯を有する。具体的には、ヒンジ機構51は、例えば、第一枠体33に設けられた軸部51aおよび軸部51bと、第二枠体34に設けられるとともに、軸孔51cを有するアーム部51dと、を備える。軸部51aは、連結管部31の軸孔48に第一枠体33を枢支させる。軸部51bは、軸部51aと略同一軸芯に配置される。アーム部51dは、軸孔51cに枢支された軸部51bによって、第一枠体33に第二枠体34を枢支させる。   The pair of hinge mechanisms 51 have tilting axes that are positioned on the same line. Specifically, the hinge mechanism 51 includes, for example, a shaft portion 51a and a shaft portion 51b provided in the first frame body 33, an arm portion 51d provided in the second frame body 34 and having a shaft hole 51c, Is provided. The shaft portion 51 a pivotally supports the first frame 33 in the shaft hole 48 of the connecting tube portion 31. The shaft portion 51b is disposed on substantially the same axis as the shaft portion 51a. The arm portion 51d causes the first frame 33 to pivotally support the second frame 34 by the shaft portion 51b pivotally supported by the shaft hole 51c.

なお、連結管部31の軸孔48、第一枠体33の軸部51aおよび軸部51b、第二枠体34の軸孔51cは、連結管部31に対して第一枠体33および第二枠体34を互いに独立させて傾動自在に軸支させることが可能な範囲であれば、軸と孔との組み合わせを適宜に変更しても良い。また、第一枠体33および第二枠体34の双方を連結管部31に直接軸支させても良い。   Note that the shaft hole 48 of the connecting pipe portion 31, the shaft portion 51 a and the shaft portion 51 b of the first frame body 33, and the shaft hole 51 c of the second frame body 34 are connected to the first frame body 33 and the first frame body 31. The combination of the shaft and the hole may be appropriately changed as long as the two frame bodies 34 can be pivotally supported independently of each other. Further, both the first frame body 33 and the second frame body 34 may be directly supported by the connecting pipe portion 31.

第二枠体34の枠本体34aは、第一枠体33の枠本体33aよりも厚く形成される。これにより、第二ブラシ37の根本がかさ上げされ、第二ブラシ37よりも第一ブラシ36のほうが長い毛足を有する。   The frame main body 34 a of the second frame 34 is formed thicker than the frame main body 33 a of the first frame 33. As a result, the root of the second brush 37 is raised, and the first brush 36 has a longer leg than the second brush 37.

第一ブラシ36および第二ブラシ37は、それぞれコ字状に形成された枠本体33a、34aと、枠本体33a、34aの開放端に設けられたヒンジ機構51とによって、第一枠体33および第二枠体34の傾動軸芯から遠ざかるほど、傾動軸芯に平行な線上に並ぶ毛束35aが増え、ブラシ全体としての腰(弾力)が強くなる。換言すれば、第一ブラシ36および第二ブラシ37は、第一枠体33および第二枠体34の傾動軸芯から遠ざかるほど部分的な剛性が増す。   The first brush 36 and the second brush 37 are each formed by a frame body 33a, 34a formed in a U-shape and a hinge mechanism 51 provided at an open end of the frame body 33a, 34a. As the distance from the tilt axis of the second frame 34 increases, the hair bundles 35a arranged on a line parallel to the tilt axis increases and the waist (elasticity) of the entire brush becomes stronger. In other words, the partial rigidity of the first brush 36 and the second brush 37 increases as the distance from the tilt axis of the first frame 33 and the second frame 34 increases.

次に、本実施形態に係る電気掃除機1の掃除動作を説明する。   Next, the cleaning operation of the electric vacuum cleaner 1 according to the present embodiment will be described.

電気掃除機1のユーザは、先ず、掃除機本体2に集塵ホース3、延長管7、吸込口体8を適宜の順序で接続する。   The user of the electric vacuum cleaner 1 first connects the dust collecting hose 3, the extension pipe 7, and the suction port body 8 to the cleaner main body 2 in an appropriate order.

次に、掃除機本体2から電源コード16を引き出し、商用電源を供給するコンセント(図示省略)に電源プラグ23を接続する。   Next, the power cord 16 is pulled out from the cleaner body 2, and the power plug 23 is connected to an outlet (not shown) for supplying commercial power.

次に、電気掃除機1のユーザは、把持部5を把持して起動スイッチ26を操作する。そうすると、起動スイッチ26で設定された動作モードに応じて電動送風機12が作動する。   Next, the user of the vacuum cleaner 1 operates the start switch 26 while holding the holding part 5. Then, the electric blower 12 operates according to the operation mode set by the start switch 26.

次いで、電気掃除機1のユーザは、把持部5を把持したまま手元操作管4および延長管7を前後に往復する。そうすると、吸込口体8は、被掃除面上を前後に往復走行する。このとき、電気掃除機1は、空気とともに被掃除面の塵埃を吸込口体8の吸込口に吸い込む。   Next, the user of the vacuum cleaner 1 reciprocates the hand operating tube 4 and the extension tube 7 back and forth while holding the grip portion 5. Then, the suction port body 8 travels back and forth on the surface to be cleaned. At this time, the vacuum cleaner 1 sucks dust on the surface to be cleaned together with air into the suction port of the suction port body 8.

吸込口体8に吸い込まれた含塵空気は、延長管7、手元操作管4および集塵ホース3と順次に通過した後、掃除機本体2の内部に吸い込まれる。   The dust-containing air sucked into the suction port body 8 sequentially passes through the extension pipe 7, the hand operation pipe 4 and the dust collecting hose 3, and then sucked into the cleaner body 2.

含塵空気に含まれた塵埃は、掃除機本体2に収容された塵埃分離集塵部14で捕集される。   Dust contained in the dust-containing air is collected by the dust separating and collecting unit 14 accommodated in the cleaner body 2.

塵埃が分離された空気は、さらに電動送風機12を通過し、掃除機本体2の排気口から排気される。   The air from which the dust has been separated further passes through the electric blower 12 and is exhausted from the exhaust port of the cleaner body 2.

そして、吸込口体8を用いた掃除が困難な被掃除面、例えば、吸込口体8を侵入させることが困難な家具と家具との間の狭隘な隙間を掃除する場合、電気掃除機1のユーザは、延長管7から吸込口体8を取り外す。そうすると、アタッチメント28は、使用可能な状態となる(図3)。   And when cleaning the to-be-cleaned surface which is difficult to clean using the suction inlet body 8, for example, the narrow gap between the furniture where it is difficult to make the suction inlet body 8 enter, The user removes the suction port body 8 from the extension pipe 7. Then, the attachment 28 is in a usable state (FIG. 3).

次に、電気掃除機1のユーザは、アタッチメント28の第一ブラシ36および第二ブラシ37の毛先を被掃除面に当接し、アタッチメント28を隙間に侵入させる。   Next, the user of the vacuum cleaner 1 brings the hair tips of the first brush 36 and the second brush 37 of the attachment 28 into contact with the surface to be cleaned, and causes the attachment 28 to enter the gap.

図7は、本発明の実施形態に係るアタッチメントを示した斜視図である。   FIG. 7 is a perspective view showing an attachment according to the embodiment of the present invention.

図8は、本発明の実施形態に係るアタッチメントを示した長手軸方向の断面図である。   FIG. 8 is a cross-sectional view in the longitudinal axis direction showing the attachment according to the embodiment of the present invention.

図7および図8に示すように、電気掃除機1のアタッチメント28は、電気掃除機1のユーザから把持部5、手元操作管4および延長管7を介して被掃除面Fに操作力fで押圧される。   As shown in FIGS. 7 and 8, the attachment 28 of the vacuum cleaner 1 is operated by the operation force f on the surface F to be cleaned from the user of the vacuum cleaner 1 through the grip portion 5, the hand operation tube 4 and the extension tube 7. Pressed.

そうすると、当初は被掃除面に一様に押圧されていた第一ブラシ36および第二ブラシ37は、徐々に湾曲する。このとき、第二ブラシ37は、第一ブラシ36よりも毛足が短く剛性が高いため、操作力fをより積極的に分担する。また、第一ブラシ36は、ケーシング32による傾動角度の規制を受けておらず、分担する操作力fの反力で被掃除面Fから遠ざかる方向へと傾動される。さらに、第二ブラシ37は、第一枠体33および第二枠体34の傾動軸芯から遠ざかるほど部分的な剛性が高いので、傾動軸芯から遠ざかる部分ほど操作力fをより積極的に分担し、傾動軸芯に近い部分では操作力fによって大きく湾曲される。なお、図8中、第一ブラシ36および第二ブラシ37の毛束35aが湾曲される部分を一点鎖線で示す。   Then, the first brush 36 and the second brush 37 that were initially pressed uniformly against the surface to be cleaned are gradually curved. At this time, since the second brush 37 has a shorter bristle and higher rigidity than the first brush 36, the operating force f is more actively shared. Further, the first brush 36 is not regulated by the tilt angle by the casing 32, and is tilted away from the surface to be cleaned F by the reaction force of the operating force f to be shared. Furthermore, since the second brush 37 has higher partial rigidity as it moves away from the tilt axis of the first frame 33 and the second frame 34, the operation force f is more actively shared as the part is further away from the tilt axis. However, the portion near the tilt axis is greatly bent by the operating force f. In FIG. 8, a portion where the hair bundle 35a of the first brush 36 and the second brush 37 is curved is indicated by a one-dot chain line.

このようにして、第一ブラシ36および第二ブラシ37は、第二ブラシ37によって操作力fを主に分担し、第二ブラシ37の剛性分布による変位量の差によって第一ブラシ36を被掃除面Fから引き起こす。   In this way, the first brush 36 and the second brush 37 mainly share the operating force f by the second brush 37, and the first brush 36 is cleaned by the difference in displacement due to the rigidity distribution of the second brush 37. Cause from face F.

この状態で、アタッチメント28を隙間に侵入させると、被掃除面F上の塵埃は、第一ブラシ36と被掃除面Fとの間に形成された隙間を通って連結管部31の開口44の下方に案内される。この塵埃は、開口44から吸い込まれ、または第二ブラシ37によって被掃除面Fから掃き取られて開口44から吸い込まれる。このとき、開口44の周囲は、第一ブラシ36と被掃除面Fとの間に形成された隙間を除いて略全周がブラシ35によって囲まれているので、開口44から吸い込まれる空気の流速の低下を十分に抑制できる。   In this state, when the attachment 28 is caused to enter the gap, dust on the surface to be cleaned F passes through the gap formed between the first brush 36 and the surface to be cleaned F in the opening 44 of the connecting pipe portion 31. Guided downward. The dust is sucked from the opening 44 or is swept from the surface to be cleaned F by the second brush 37 and sucked from the opening 44. At this time, since the entire circumference of the opening 44 is surrounded by the brush 35 except for the gap formed between the first brush 36 and the surface F to be cleaned, the flow velocity of the air sucked from the opening 44 Can be sufficiently suppressed.

このとき、ガイド凹部52の曲面52aは、連結管部31の開口44の縁部31cに略連続的に繋がる。   At this time, the curved surface 52 a of the guide recess 52 is connected substantially continuously to the edge 31 c of the opening 44 of the connecting pipe portion 31.

なお、アタッチメント28は、電気掃除機1のユーザが把持部5を把持し、延長管7を適宜の角度で被掃除面に延在させた状態で、第二ブラシ37の毛先が略一様に被掃除面に当接するような傾動角度に第二枠体34を固定させても、同様な作用、効果を奏することができる。   In addition, the attachment 28 has a hair tip of the second brush 37 substantially uniform in a state in which the user of the vacuum cleaner 1 holds the grip portion 5 and the extension tube 7 extends to the surface to be cleaned at an appropriate angle. Even if the second frame 34 is fixed at a tilting angle so as to come into contact with the surface to be cleaned, similar actions and effects can be obtained.

本実施形態によれば、アタッチメント28のブラシ35の毛先を被掃除面Fに押し当てることで第一枠体33および第一ブラシ36と第二枠体34および第二ブラシ37とをそれぞれ独立に傾動させ、第二ブラシ37を被掃除面Fに確実に押し当てつつ、第一ブラシ36と被掃除面Fとの間に適宜の隙間を形成できる。これにより、アタッチメント28は、吸込口である開口44をブラシ35によって極力囲みつつ、かつ、第一ブラシ36と被掃除面Fとの間に形成された隙間によってアタッチメント28の進行方向に存する被掃除面F上の塵埃を円滑に案内できるとともに、第二ブラシ37によって被掃除面Fから確実に掃き掃き取ることができる。したがって、アタッチメント28は、ブラシ35に掃かれた塵埃が開口44から遠ざかる方向へ掃き出されてしまうことがない。   According to the present embodiment, the first frame body 33 and the first brush 36, the second frame body 34 and the second brush 37 are made independent by pressing the tip of the brush 35 of the attachment 28 against the surface F to be cleaned. It is possible to form an appropriate gap between the first brush 36 and the surface to be cleaned F while reliably pressing the second brush 37 against the surface F to be cleaned. Thereby, the attachment 28 surrounds the opening 44 that is a suction port with the brush 35 as much as possible, and is to be cleaned existing in the traveling direction of the attachment 28 by the gap formed between the first brush 36 and the surface F to be cleaned. The dust on the surface F can be smoothly guided and can be reliably swept away from the surface F to be cleaned by the second brush 37. Therefore, the attachment 28 is not swept away in a direction in which the dust swept by the brush 35 moves away from the opening 44.

また、本実施形態によれば、ブラシ35を被掃除面に当接させた状態において第一ブラシ36と被掃除面Fとの間に形成される隙間を、被掃除面F上の塵埃を開口44に円滑に案内可能な範囲で極力狭く構成することが容易であり、これによって開口44に吸い込まれる空気の流速を適宜に高めることができる。   In addition, according to the present embodiment, a gap formed between the first brush 36 and the surface to be cleaned F is opened in a state where the brush 35 is in contact with the surface to be cleaned, and dust on the surface to be cleaned F is opened. It is easy to configure as narrow as possible within a range that can be smoothly guided to 44, and thereby the flow velocity of air sucked into the opening 44 can be appropriately increased.

したがって、本発明の実施形態によれば、被掃除面Fにおける塵埃の掃き集め易さと、掃き集めた塵埃を吸い込む力とを両立できる。   Therefore, according to the embodiment of the present invention, it is possible to achieve both the ease of dust collection on the surface F to be cleaned and the force to suck the dust collected.
