Description
本発明は電気掃除機用吸込具に関するもの、及びこの吸込具を用いた電気掃除機に関する。 The present invention relates to a vacuum cleaner suction tool and to a vacuum cleaner using the suction tool.
従来の電気掃除機の吸込具として、回転清掃体とこの回転清掃体を駆動する駆動モータとを備える吸込具本体と、前記吸込具本体を形成する吸込具下ケース、および吸込具上ケースと、前記吸込具下ケースに設けられ、前記回転清掃体を収納する開口部と、この開口部の下面側から前面側にかけて設けた吸込口とを有するものがある。前記の構成において、回転清掃体と、回転清掃体を固定する開口部の壁面の間には、回転清掃体がスムーズに回動するようにするために、クリアランスが設けられている。 As a suction tool of a conventional vacuum cleaner, a suction tool body including a rotary cleaning body and a drive motor that drives the rotary cleaning body, a suction tool lower case that forms the suction tool body, and a suction tool upper case, There is one provided in the lower case of the suction tool and having an opening for storing the rotary cleaning body and a suction port provided from the lower surface side to the front surface side of the opening portion. In the above configuration, a clearance is provided between the rotary cleaning body and the wall surface of the opening that fixes the rotary cleaning body in order to smoothly rotate the rotary cleaning body.
又、以下の特許文献１〜３に示すように、ブラシバネを配置することでクリアランスを調節するものも提案されていた。 In addition, as shown in the following Patent Documents 1 to 3, there has been proposed a method in which a clearance is adjusted by arranging a brush spring.
特許文献１（特開平６−３０４１００号公報）で提案されているように回転清掃体の一端にブラシバネを配設し、回転清掃体をスラスト方向に移動可能とし、この移動により回転清掃体の着脱を可能にした構造が提案されている。 As proposed in Patent Document 1 (Japanese Patent Laid-Open No. 6-304100), a brush spring is disposed at one end of the rotary cleaning body so that the rotary cleaning body can be moved in the thrust direction. A structure that enables this is proposed.
特許文献２（特開平６−２６９３８１号公報）では吸込具体に、電動機からの回転駆動力を回転清掃体に伝達する駆動ギヤにブラシバネを設け、前記回転清掃体を着脱自在に取り付けが可能とした構造が提案されている。 In Patent Document 2 (Japanese Patent Laid-Open No. 6-269281), specifically, a suction spring is provided on a drive gear that transmits a rotational driving force from an electric motor to the rotary cleaning body, and the rotary cleaning body can be detachably attached. A structure has been proposed.
特許文献３（特開昭６２−２０７４２２号公報）では吸込具体に配設された回転清掃体の軸線方向の遊びを調節するために、軸受と回転清掃体の間にブラシバネを配設した構造が提案されている Patent Document 3 (Japanese Patent Laid-Open No. 62-207422) has a structure in which a brush spring is provided between the bearing and the rotary cleaning body in order to adjust the play in the axial direction of the rotary cleaning body arranged specifically for suction. Proposed
前記記載の背景技術では、以下のような課題が考えられる。 In the background art described above, the following problems can be considered.
前記背景技術にある回転清掃体と回転清掃体を固定する開口部の壁面にクリアランスを設ける構造の場合、一般的に強度が必要となる回転清掃体は、そのブラシコアを金属や、強化繊維入りの樹脂で製作するため、開口部を有する下ケースよりも雰囲気温度による収縮量が小さくなる恐れがある。 In the case of a structure in which clearance is provided in the wall surface of the opening that fixes the rotary cleaning body and the rotary cleaning body in the background art, the rotary cleaning body that generally requires strength is made of a brush core containing metal or reinforcing fibers. Since it is made of resin, the shrinkage due to the ambient temperature may be smaller than that of the lower case having the opening.
そのため、前記吸込具を雰囲気温度の低い環境で使用した際には、回転清掃体と下ケースとのスラスト方向のクリアランスが狭くなり、回転清掃体が下ケースに押し付けられ摺動面が融解することで回転不良が発生するという恐れがある。 Therefore, when the suction tool is used in an environment where the ambient temperature is low, the clearance in the thrust direction between the rotary cleaning body and the lower case becomes narrow, and the rotary cleaning body is pressed against the lower case and the sliding surface is melted. There is a risk of rotation failure.
又、例えば前記吸込具を雰囲気温度の高い環境で使用した際には、回転清掃体と下ケースとのスラスト方向のクリアランスが広がり、回転清掃体が回転駆動した時に、前記回転清掃体が下ケースとのクリアランスで振動することで異音が発生するという恐れがある。 Further, for example, when the suction tool is used in an environment with a high ambient temperature, the clearance in the thrust direction between the rotary cleaning body and the lower case is widened, and when the rotary cleaning body is driven to rotate, the rotary cleaning body is moved to the lower case. There is a risk that abnormal noise will occur due to vibration with the clearance.
又、特許文献１では、回転ブラシ体に固定された軸を軸受が回転自在に保持しており、軸の外周にブラシバネが設けられている構造である。回転ブラシ体は軸を固定するために中実で形成されており、圧入固定するために軸長が長くなっている。そのため回転ブラシ体の質量が重くなるという恐れがある。 In Patent Document 1, a shaft fixed to a rotating brush body is rotatably held by a bearing, and a brush spring is provided on the outer periphery of the shaft. The rotating brush body is solid to fix the shaft, and has a long shaft length for press-fitting and fixing. Therefore, there is a possibility that the mass of the rotating brush body becomes heavy.
又、特許文献２では、回転清掃体に電動機からの回転駆動力を回転清掃体に伝達する駆動ギヤにブラシバネを設け、前記ブラシバネの内径の間にブラシコアの端部を挿入し、前記回転清掃体を着脱自在とした構造である。このような構造では、回転清掃体を構成するブラシコアの外周部にブラシバネがむき出しの状態となっているために、ブラシバネに糸くずなどのごみが絡み易くなっているという恐れがある。 In Patent Document 2, a brush spring is provided in a drive gear that transmits a rotational driving force from an electric motor to the rotary cleaning body, and an end portion of a brush core is inserted between the inner diameters of the brush springs. This is a structure that can be freely attached and detached. In such a structure, since the brush spring is exposed on the outer peripheral portion of the brush core constituting the rotary cleaning body, there is a risk that dust such as lint is easily entangled with the brush spring.
又、特許文献３では、回転清掃体のブラシコアの内部を中空にして回転軸を通し、回転軸の両端を軸受で固定し、前記軸受とブラシコアの軸受当接面との間にブラシバネが設けられている構造である。このような構造では、ブラシコア内部にブラシバネを配設しているために回転清掃体の外径が大きくなり、これにより吸込具体の高さが高くなってしまうため、狭い隙間の掃除がしにくくなる等、使い勝手の悪化が懸念される。 In Patent Document 3, the inside of the brush core of the rotary cleaning body is hollowed, the rotary shaft is passed through, both ends of the rotary shaft are fixed with bearings, and a brush spring is provided between the bearing and the bearing contact surface of the brush core. It is a structure. In such a structure, since the brush spring is disposed inside the brush core, the outer diameter of the rotary cleaning body is increased, and this increases the specific suction height, which makes it difficult to clean a narrow gap. There are concerns about the deterioration of usability.
さらに、ブラシコア内部に回転軸を通しているため、回転ブラシ体の質量が重くなるという恐れがある。 Furthermore, since the rotating shaft is passed through the brush core, the mass of the rotating brush body may become heavy.
本発明の目的は、これらの問題を解決し、回転清掃体が雰囲気温度の変化による影響を受けず、軽量で、ごみが絡みにくく、使い勝手の良い電気掃除機用吸込具を提供することにある。 An object of the present invention is to solve these problems, and to provide a vacuum cleaner suction tool that is easy to use because the rotary cleaning body is not affected by changes in ambient temperature, is lightweight, is not easily entangled with dust. .

本発明によれば、回転清掃体保持部の内部に付勢手段（ブラシバネ）が配設されることで回転清掃体がスラスト方向に対して移動可能となっている。 According to the present invention, the urging means (brush spring) is disposed inside the rotary cleaning body holding portion, so that the rotary cleaning body can move in the thrust direction.
ここで、例えば、前記吸込具を雰囲気温度の低い環境で使用した際には、回転清掃体と下ケースとの軸方向のクリアランスが狭くなるが、回転清掃体保持部の内部に付勢手段（ブラシバネ）を配設することで、付勢手段（ブラシバネ）が圧縮されて、回転清掃体と下ケースとの収縮差を吸収することにより、回転清掃体が下ケースに押し付けられることが無いため、回転不良を防止することができる。 Here, for example, when the suction tool is used in an environment where the ambient temperature is low, the axial clearance between the rotary cleaning body and the lower case is narrowed, but the biasing means ( By arranging the (brush spring), the biasing means (brush spring) is compressed, and the rotational cleaning body is not pressed against the lower case by absorbing the shrinkage difference between the rotary cleaning body and the lower case. Rotational failure can be prevented.
又、例えば、前記吸込具を雰囲気温度の高い環境で使用した際には、回転清掃体と下ケースとの軸方向の隙間が広くなるが、付勢手段（ブラシバネ）が軸受を回転清掃体の外向き方向へ押しているため、回転清掃体のスラスト方向の振動を抑制し、前記回転清掃体が下ケースとのクリアランスでの異音発生を防止することができる。 Also, for example, when the suction tool is used in an environment with a high ambient temperature, the axial clearance between the rotary cleaning body and the lower case is widened, but the biasing means (brush spring) causes the bearing to Since it is pushing in the outward direction, vibration in the thrust direction of the rotary cleaning body can be suppressed, and abnormal rotation can be prevented from occurring in the clearance between the rotary cleaning body and the lower case.
又、回転清掃体の回転駆動時のスラスト方向の振動を付勢手段（ブラシバネ）が吸収することにより、吸込具騒音を静音化することができる。 In addition, the suction tool noise can be reduced by the urging means (brush spring) absorbing the vibration in the thrust direction when the rotary cleaning body is driven to rotate.
又、回転清掃体保持部はブラシコアへのシャフトによる固定が不要となるため、前記回転清掃体保持部とブラシコアを別部品で構成し、ブラシコア中空とすることで、回転清掃体を軽量化することができる。 In addition, since the rotary cleaning body holding part does not need to be fixed to the brush core by the shaft, the rotary cleaning body holding part and the brush core are configured as separate parts, and the brush core is hollow, thereby reducing the weight of the rotary cleaning body. Can do.
又、回転清掃体保持部は、前記回転清掃体保持部の内部に付勢手段（ブラシバネ）が配設されることにより、付勢手段（ブラシバネ）部がブラシコアの外周部に露出していないため、付勢手段（ブラシバネ）部へごみの侵入がなく、糸がらみ等を防止することができる。 In addition, since the urging means (brush spring) is not exposed to the outer peripheral portion of the brush core because the urging means (brush spring) is disposed inside the rotative cleaning body holding part. Further, there is no entry of dust into the urging means (brush spring) portion, and yarn slack can be prevented.

回転清掃体２０４の両端には、前記回転清掃体を前記吸込具本体へ保持する保持部材Ａ１１０，回転清掃体保持部１１８が設けられている。保持部材Ａ１１０は、シタケース内部に設けられた保持部材Ｂ４０８の凹凸噛合部Ａ７０１と噛合う凹凸からなる噛合部Ｂ１１２を有し、保持部材Ａ１１０と保持部材Ｂ４０８で回動力を伝える役割を果たす。 At both ends of the rotary cleaning body 204, a holding member A110 for holding the rotary cleaning body on the suction tool main body and a rotary cleaning body holding portion 118 are provided. The holding member A110 has a meshing portion B112 formed by unevenness that meshes with the unevenness engaging portion A701 of the holding member B408 provided in the inner case, and plays a role of transmitting rotational force between the holding member A110 and the holding member B408.
図５（ａ），図５（ｂ）に本実施例による回転清掃体保持部１１８の分解斜視図と組立て図を示す。回転清掃体保持部１１８を構成する円筒状のブラシカバー１１１にはシャフト１１６が固定されており、シャフト１１６の外周にはブラシカバー１１１によって溝部１２０が形成されている。溝部にワッシャー１１４を配置し、ついでブラシバネ１１５，ワッシャー１１４の順に挿入する。その後、軸受１１３をシャフト１１６に沿って挿入し、軸受１１３がシャフト１１６に対して回転自在になるように固定されている。また、軸受１１３はブラシバネ１１５により下ケース２０１にスラスト方向（左右方向）外側に常に押し付けられた状態となっている。 5A and 5B are an exploded perspective view and an assembled view of the rotary cleaning body holding portion 118 according to this embodiment. A shaft 116 is fixed to a cylindrical brush cover 111 constituting the rotary cleaning body holding portion 118, and a groove portion 120 is formed on the outer periphery of the shaft 116 by the brush cover 111. A washer 114 is disposed in the groove, and then the brush spring 115 and the washer 114 are inserted in this order. Thereafter, the bearing 113 is inserted along the shaft 116, and the bearing 113 is fixed so as to be rotatable with respect to the shaft 116. The bearing 113 is always pressed against the lower case 201 outwardly in the thrust direction (left-right direction) by the brush spring 115.
図１（ｂ）に示すように、シャフト１１６と、ブラシカバー１１１の固定部１１１ａは、ブラシバネ１１５の内側に配置され、スラスト方向（左右方向）の位置が重なるように構成している。これにより、ブラシカバー１１１内部のスペースを有効活用し、回転清掃体保持部１１８を小型化することができる。さらにスラスト方向（左右方向）で短くすることができるので、回転清掃体２０４のスラスト方向（左右方向）の幅が長くなり、ごみ取れ幅が増え、掃除効率が上がる。 As shown in FIG. 1B, the shaft 116 and the fixing portion 111a of the brush cover 111 are disposed inside the brush spring 115, and are configured such that the positions in the thrust direction (left-right direction) overlap. Thereby, the space inside the brush cover 111 can be used effectively, and the rotary cleaning body holding part 118 can be reduced in size. Furthermore, since it can be shortened in the thrust direction (left-right direction), the width of the rotary cleaning body 204 in the thrust direction (left-right direction) is increased, the width of dust removal is increased, and the cleaning efficiency is increased.
次に本実施例の動作を説明する。掃除機使用者がハンドルグリップ３０３に設置された手元スイッチ３０４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３０１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３０２，延長管３０５を通って吸込具３０６に到達する。それと同時に、ホース体３０２および延長管３０５に設けられた電源線から供給された電源が、回路基板２０６を介して電動機２０５を駆動する。 Next, the operation of this embodiment will be described. When the vacuum cleaner user operates the hand switch 304 installed on the handle grip 303, the electric blower in the electric vacuum cleaner main body 301 is operated in an operation mode according to the operated switch. The suction force generated by the electric blower reaches the suction tool 306 through the hose body 302 and the extension pipe 305. At the same time, the power supplied from the power lines provided on the hose body 302 and the extension pipe 305 drives the electric motor 205 through the circuit board 206.
電動機２０５とプーリー４１１，ベルト４１０で連結している回転清掃体２０４が回転することにより、回転清掃体２０４の清掃部材１０７である刷毛１０５やブレード１０４によって被掃除面からごみや塵埃を掻き上げて吸い込んでいる。 When the rotary cleaning body 204 connected by the electric motor 205 and the pulley 411 and the belt 410 rotates, the brush 105 or the blade 104 which is the cleaning member 107 of the rotary cleaning body 204 scrapes dust and dust from the surface to be cleaned. I'm inhaling.
図１（ｂ）に本実施例における回転清掃体保持部１１８の断面図を示す。 FIG. 1B shows a cross-sectional view of the rotary cleaning body holding portion 118 in the present embodiment.
回転清掃体保持部１１８の内部にブラシバネ１１５を配設することにより、回転清掃体２０４がスラスト方向（左右方向）で図１（ｂ）に示す可動領域（Ａ）の範囲を移動可能とした。 By arranging the brush spring 115 inside the rotary cleaning body holding portion 118, the rotary cleaning body 204 can move in the range of the movable region (A) shown in FIG. 1B in the thrust direction (left-right direction).
これは、吸込具に回転清掃体２０４が配置された状態で、吸込具の使用時の雰囲気温度が変化しても、ブラシバネ１１５によって、回転清掃体のスラスト方向（左右方向）外側に押されることで軸受１１３が下ケース２０１に密着し、ブラシカバー１１１には密着しない状態となるように、ブラシバネ１１５による回転清掃体２０４の可動領域（Ａ）を設定した。 Even if the atmospheric temperature at the time of use of a suction tool changes in the state where the rotary cleaning body 204 is arranged in the suction tool, this is pushed outward by the brush spring 115 in the thrust direction (left-right direction) of the rotary cleaning body. Thus, the movable region (A) of the rotary cleaning body 204 by the brush spring 115 is set so that the bearing 113 is in close contact with the lower case 201 and is not in close contact with the brush cover 111.
本実施例ではブラシバネ１１５による可動領域（Ａ）は１.８mmであり、この可動領域（Ａ）であれば、例えば雰囲気温度の低い−１０℃の環境で吸込具を使用した際に、回転清掃体２０４と下ケース２０１のクリアランスが狭くなっても、ブラシバネ１１５が軸受１１３を回転清掃体２０４のスラスト方向（左右方向）外側に押し、軸受１１３がブラシカバー１１１に非接触の状態となる。逆に雰囲気温度の高い４０℃環境で吸込具３０６を使用した際に、回転清掃体２０４と下ケース２０１のクリアランスが広くなっても、ブラシバネ１１５によってスラスト方向（左右方向）外側に押された軸受１１３が下ケース２０１に密着した状態を維持できる。 In this embodiment, the movable area (A) by the brush spring 115 is 1.8 mm. If this movable area (A) is used, for example, when the suction tool is used in an environment having a low ambient temperature of −10 ° C., rotational cleaning is performed. Even when the clearance between the body 204 and the lower case 201 becomes narrow, the brush spring 115 pushes the bearing 113 outward in the thrust direction (left-right direction) of the rotary cleaning body 204, and the bearing 113 is not in contact with the brush cover 111. Conversely, when the suction tool 306 is used in a high ambient temperature environment of 40 ° C., even if the clearance between the rotary cleaning body 204 and the lower case 201 becomes wider, the bearing is pushed outward in the thrust direction (left-right direction) by the brush spring 115. The state in which 113 is in close contact with the lower case 201 can be maintained.
ここで、本実施例におけるブラシバネの荷重は０.１Ｎ以上から１０Ｎ以下と設定した。ブラシバネ荷重の下限値である０.１Ｎ未満の前記ブラシバネ荷重では回転清掃体２０４をスラスト方向（左右方向）でのガタつきを吸収するには前記ブラシバネ荷重が不足し、振動低減の効果が弱くなる。また、前記ブラシバネ荷重が１０Ｎより大きくとなるとブラシバネ１１５から回転清掃体２０４に加わる前記ブラシバネ荷重が過大であり、前記ブラシバネ荷重が加わったまま回転清掃体２０４が回転駆動すると、部品間の摺動面に関して摩擦熱による熱溶着が起こり回転不良となる。 Here, the load of the brush spring in the present embodiment was set to 0.1 N or more and 10 N or less. When the brush spring load is less than 0.1 N which is the lower limit value of the brush spring load, the brush spring load is insufficient to absorb the play in the thrust direction (left-right direction) of the rotary cleaning body 204, and the effect of reducing vibration is weakened. . When the brush spring load is greater than 10N, the brush spring load applied from the brush spring 115 to the rotary cleaning body 204 is excessive, and when the rotary cleaning body 204 is driven to rotate while the brush spring load is applied, the sliding surface between the parts As a result, heat welding due to frictional heat occurs and rotation failure occurs.
すなわち、ブラシバネ１１５による振動低減の効果が見込まれ、かつ前記ブラシバネ荷重が過負荷となり回転不良を引き起こさない値として、前記ブラシバネ荷重０.１Ｎ以上から１０Ｎ以下と設定した。 That is, the brush spring load is set to 0.1 N or more and 10 N or less as a value in which the effect of vibration reduction by the brush spring 115 is expected and the brush spring load is overloaded and does not cause rotation failure.
したがって、本実施例では一般的に強度が必要となる回転清掃体２０４のブラシコア１１７を金属や、強化繊維入りの樹脂を用いるため、開口部を有するシタケースよりも温度による収縮量が小さくなっている。 Therefore, in this embodiment, since the brush core 117 of the rotary cleaning body 204 that generally requires strength is made of metal or resin containing reinforcing fibers, the amount of shrinkage due to temperature is smaller than that of the case having an opening. .
このため、吸込具３０６を雰囲気温度の低い環境で使用した際、回転清掃体２０４と下ケース２０１の熱膨張率の違いによりスラスト方向（左右方向）のクリアランスが狭くなり、回転清掃体２０４が下ケース２０１に押し付けられるが、回転清掃体保持部１１８の内部にブラシバネ１１５を配設することにより、回転清掃体２０４と下ケース２０１との収縮差をブラシバネ１１５が吸収することができる。 For this reason, when the suction tool 306 is used in an environment where the ambient temperature is low, the clearance in the thrust direction (left-right direction) becomes narrow due to the difference in thermal expansion coefficient between the rotary cleaning body 204 and the lower case 201, and the rotary cleaning body 204 Although pressed against the case 201, the brush spring 115 can absorb the contraction difference between the rotary cleaning body 204 and the lower case 201 by disposing the brush spring 115 inside the rotary cleaning body holding portion 118.
同様に、吸込具３０６を雰囲気温度の高い環境で使用した際、回転清掃体２０４と下ケース２０１の熱膨張率の違いにより、回転清掃体２０４と下ケース２０１とスラスト方向（左右方向）のクリアランスが広くなるが、前記ブラシバネ１１５が軸受１１３を下ケース２０１に押し付けるので、回転清掃体２０４の回転駆動時の振動を吸収することができる。 Similarly, when the suction tool 306 is used in an environment with a high ambient temperature, the clearance in the thrust direction (left-right direction) between the rotary cleaning body 204 and the lower case 201 due to the difference in thermal expansion coefficient between the rotary cleaning body 204 and the lower case 201. However, since the brush spring 115 presses the bearing 113 against the lower case 201, it is possible to absorb vibration when the rotary cleaning body 204 is driven to rotate.
また、回転清掃体保持部１１８とブラシコア１１７が別体で構成されるため、ブラシコアを中空に形成することが可能となり、回転清掃体２０４の軽量化が図れる。 Moreover, since the rotary cleaning body holding part 118 and the brush core 117 are comprised separately, it becomes possible to form a brush core hollow, and the weight reduction of the rotary cleaning body 204 can be achieved.
図６に本実施例による回転清掃体２０４の取り外し方を示す。 FIG. 6 shows how to remove the rotary cleaning body 204 according to this embodiment.
吸込具の下面側を上面側に向ける。係止部材２２０の操作部に操作者の指を添え、吸込具中央側から外側に回動し、軸受押さえ部材４０７と係止部材２２０の係合を解除する（Ｘ）。そして、下ケース２０１から軸受押さえ部材４０７を開け、軸受押さえ部材４０７を外す（Ｙ）。 The lower surface side of the suction tool is directed to the upper surface side. An operator's finger is attached to the operation portion of the locking member 220, and the finger is turned outward from the suction tool center side to release the engagement between the bearing pressing member 407 and the locking member 220 (X). Then, the bearing pressing member 407 is opened from the lower case 201, and the bearing pressing member 407 is removed (Y).
次に、軸受１１３を回転清掃体２０４のスラスト方向（左右方向）の内向きに押し、下ケース２０１との接触を解除した状態で、回転清掃体２０４を、上方に引き上げることにより、回転清掃体２０４の保持部材Ａ１１０の噛合部１１２と保持部材Ｂ４０８の噛合部７０１が外れ、吸込具３０６から離脱できる（Ｚ）。 Next, the bearing 113 is pushed inward in the thrust direction (left-right direction) of the rotary cleaning body 204, and the rotary cleaning body 204 is lifted upward in a state where the contact with the lower case 201 is released, thereby rotating the rotary cleaning body. The engaging portion 112 of the holding member A110 204 and the engaging portion 701 of the holding member B408 are disengaged and can be detached from the suction tool 306 (Z).
これにより、回転清掃体２０４の刷毛１０８に糸くず等が付着した際も容易に回転清掃体２０４を取り外し、簡単に糸くずなどの繊維状のものや、髪の毛等を取り除くことができる。 Thereby, even when lint or the like adheres to the brush 108 of the rotary cleaning body 204, the rotary cleaning body 204 can be easily removed, and fiber such as lint, hair, or the like can be easily removed.
取り付け時は回転清掃体２０４の端部に固定された軸受１０３を回転清掃体のスラスト方向（左右方向）内側に押しこみながら、回転清掃体２０４の保持部材Ａ１１０の噛合部１１２と保持部材Ｂ４０８の噛合部７０１を合わせ、吸込具３０６にはめ込む。 At the time of installation, the bearing 103 fixed to the end of the rotary cleaning body 204 is pushed inward in the thrust direction (left-right direction) of the rotary cleaning body 204, while the meshing portion 112 of the holding member A110 of the rotary cleaning body 204 and the holding member B408 are The meshing portion 701 is aligned and fitted into the suction tool 306.
この時、回転清掃体保持部１１８の内部に配設されたブラシバネ１１５が軸受１１３を下ケース２０１に押し付けることで、不意に吸込具を下に向けた時などに回転清掃体２０４が外れにくくなっている。 At this time, the brush spring 115 disposed inside the rotary cleaning body holding portion 118 presses the bearing 113 against the lower case 201, so that the rotary cleaning body 204 is unlikely to come off when the suction tool is unexpectedly turned downward. ing.
本発明の各実施例は床移動型の掃除機だけでなく、アップライト式やスティック式の掃除機にも適用できる。モータ駆動方式の吸込具だけでなく、エアー駆動方式にも適用できる。 Each embodiment of the present invention can be applied not only to a floor moving type vacuum cleaner but also to an upright type or stick type vacuum cleaner. It can be applied not only to motor-driven suction tools but also to air-driven systems.
また、本発明の各実施例においてブラシバネを用いたがこれに限るものではない。軸受を前記回転清掃体の外向きへ押す（付勢する）機能を有するものであれば良く、バネのほかにゴムなどの弾性材料などの付勢手段でも同様の効果を奏する。 Moreover, although the brush spring was used in each Example of this invention, it is not restricted to this. What is necessary is just to have a function which pushes a bearing to the said rotation cleaning body outward (urging | biasing), and there exists the same effect also in biasing means, such as elastic materials, such as rubber | gum other than a spring.
