That is, the cam portion 68 has a first region 75 with a relatively small amount of protrusion in the radial direction and a second region 76 with a relatively large amount of protrusion in the radial direction with respect to the main body shaft portion 62. is doing.

第１領域75は、アーム部72が検出スイッチ71側から離間されてこの検出スイッチ71をオフ状態に設定することで吸込口本体11の走行方向を前進方向と検出する領域であり、カム部68の平面視の中心に対する中心角が、カム部68の平面視の中心に対する中心角が略１８０°となる半円形状の領域である。   The first region 75 is a region in which the arm portion 72 is separated from the detection switch 71 side and the detection switch 71 is set to an off state, whereby the traveling direction of the suction port body 11 is detected as the forward direction. The center angle with respect to the center of the planar view is a semicircular region in which the center angle with respect to the center of the cam portion 68 in the plan view is approximately 180 °.

第２領域76は、検出ローラ74を介してアーム部72を検出スイッチ71側へと押し込んでこの検出スイッチ71をオン状態に設定することで吸込口本体11の走行方向を後進方向と検出する領域であり、カム部68の平面視の中心に対する中心角が、第１領域75の中心角との和が３６０°となる角度、すなわち、本実施の形態では略１８０°となる半円形状の領域である。   The second area 76 is an area in which the arm 72 is pushed to the detection switch 71 side via the detection roller 74 and the detection switch 71 is turned on to detect the traveling direction of the suction inlet body 11 as the reverse direction. A semicircular region in which the central angle with respect to the center of the cam portion 68 in plan view is 360 ° with the central angle of the first region 75, that is, approximately 180 ° in the present embodiment. It is.

そして、各領域75，76の外周部に沿って検出手段67の検出ローラ74が転がり接触することで、アーム部72の検出スイッチ71に対する突出量が変化することにより、検出手段67にて旋回輪48の旋回輪本体57の旋回角度を検出し、この検出結果が制御手段28へと出力されるように構成されている。   Then, when the detection roller 74 of the detection means 67 is brought into rolling contact along the outer periphery of each of the regions 75 and 76, the amount of protrusion of the arm portion 72 with respect to the detection switch 71 changes, so that the detection means 67 makes a turning wheel. The turning angle of the 48 turning wheel main bodies 57 is detected, and the detection result is output to the control means 28.

各軸支板部64は、本体軸部62の中心軸である旋回輪本体57の旋回軸Ａに対してこの本体軸部62の径方向に偏心した位置へと先端側が傾斜状に延設され、平面視で旋回軸孔61の周縁部と略重なる位置にてローラ58の両側を軸支している。なお、各軸支板部64の偏心方向は、カム部68の偏心方向と所定の対応関係を有するように設定されており、本実施の形態では、カム部68の偏心方向と同方向へと偏心している。   Each shaft support plate portion 64 is inclined at the tip side to a position eccentric in the radial direction of the main body shaft portion 62 with respect to the swivel axis A of the swivel ring main body 57 that is the central axis of the main body shaft portion 62. The two sides of the roller 58 are pivotally supported at a position substantially overlapping with the peripheral edge portion of the turning shaft hole 61 in plan view. The eccentric direction of each shaft support plate portion 64 is set so as to have a predetermined correspondence with the eccentric direction of the cam portion 68, and in this embodiment, the eccentric direction of the cam portion 68 is the same direction. Eccentric.

したがって、ローラ58は、旋回輪本体57の旋回軸Ａに対して偏心した位置に回動自在に軸支され、床面との接触抵抗により、旋回輪48の旋回輪本体57が、吸込口体９の移動方向である走行方向の後側へとローラ58が追従するように旋回可能に構成されている。   Therefore, the roller 58 is pivotally supported at a position eccentric with respect to the turning axis A of the turning wheel body 57, and the turning wheel body 57 of the turning wheel 48 is sucked into the suction port by contact resistance with the floor surface. 9 is configured to be able to turn so that the roller 58 follows to the rear side in the traveling direction, which is the moving direction of N.

ここで、ローラ58は、例えばゴム、あるいはエラストマなどの、可撓性を有する部材により略円筒状に形成された車輪本体としてのローラ本体77を備え、このローラ本体77の外周面に、複数の接触部としてのギア部78が突設されている。   Here, the roller 58 includes a roller body 77 as a wheel body formed in a substantially cylindrical shape by a flexible member such as rubber or elastomer, and a plurality of rollers 58 are provided on the outer peripheral surface of the roller body 77. A gear part 78 as a contact part is projected.

ローラ本体77は、軸方向の一端側が閉塞されているとともに、軸方向の他端側が開放されている。   The roller body 77 is closed at one end side in the axial direction and opened at the other end side in the axial direction.

ギア部78は、ローラ本体77の軸方向の他端側の外周面全周に亘って、ローラ本体77の軸方向に沿ってリブ状に、かつ、径方向に突出して設けられている。そして、このギア部78は、吸込口体９を床面上に載置した状態で床面に接触する部分である。したがって、ローラ本体77側は、床面に対して殆ど接触しないように構成されている。   The gear portion 78 is provided in a rib shape along the axial direction of the roller main body 77 and projecting in the radial direction over the entire outer peripheral surface on the other end side in the axial direction of the roller main body 77. And this gear part 78 is a part which contacts a floor surface in the state which mounted the suction inlet 9 on the floor surface. Therefore, the roller body 77 side is configured so as to hardly contact the floor surface.

なお、ローラ58の軸支位置は、旋回輪本体57の旋回軸Ａからの距離が遠い方が、旋回輪48が旋回しやすくなるものの、距離を遠くしすぎると吸込口本体９の大型化を招くおそれがあるので、それらのバランスを考慮して適宜設定する。   It should be noted that the pivoting position of the roller 58 is such that the turning wheel 48 is easier to turn when the turning wheel body 57 is far from the turning axis A, but if the distance is too long, the suction port body 9 becomes larger. Since there is a possibility of incurring, it is set appropriately in consideration of the balance.

また、上ケース17は、モータ室22および制御室24の上部を覆っている。   The upper case 17 covers the upper portions of the motor chamber 22 and the control chamber 24.

Each support side wall 88 is formed with a substantially circular engagement notch 89 as a connecting portion, and each engagement notch 89 is supported by a support space 88 as a mounting opening provided in the rear portion. Communicates with the outside. Further, the upper front cover 85 is provided with a cover torsion spring (not shown) as case member urging means between the rotation restriction step surface S of the lower case 16 constituting the rear upper side of the suction chamber 21 and moves forward. It is energized.

係合切欠89は、着脱空間90を介して、回転清掃体26の回転軸31の端部と軸受34との間の位置に嵌合可能となるように形成されている。したがって、係合切欠89は、回転軸31の直径寸法よりも若干大きい内径寸法を有しているとともに、着脱空間90は、回転軸31の直径寸法よりも若干小さい空間に設定され、この着脱空間90が係合切欠89に挿入された回転軸31を抜け止め保持可能に構成されている。   The engagement notch 89 is formed so as to be fitted at a position between the end of the rotary shaft 31 of the rotary cleaning body 26 and the bearing 34 via the attachment / detachment space 90. Accordingly, the engagement notch 89 has an inner diameter dimension slightly larger than the diameter dimension of the rotating shaft 31, and the attaching / detaching space 90 is set to a space slightly smaller than the diameter dimension of the rotating shaft 31, and this attaching / detaching space is set. 90 is configured to prevent the rotation shaft 31 inserted into the engagement notch 89 from being detached.

ヒンジ86は、上前カバー85の下端部から長手方向すなわち左右方向に離間されて複数突設された突部91と、下前カバー87の上端部から長手方向に離間されて複数突設された突部92とが互いに嵌合し、これら突部91，92を貫通して支持軸93が配設されることにより構成されている。この支持軸93には、回動付勢手段としてのトーションばね94が取り付けられ、このトーションばね94が下前カバー87を上前カバー85に対して前方へと回動付勢するように構成されている。   The hinge 86 is provided with a plurality of protrusions 91 protruding in the longitudinal direction, that is, in the left-right direction from the lower end portion of the upper front cover 85, and a plurality of protrusions being spaced apart in the longitudinal direction from the upper end portion of the lower front cover 87. The protrusions 92 are fitted with each other, and a support shaft 93 is disposed through the protrusions 91 and 92. The support shaft 93 is provided with a torsion spring 94 as a rotation urging means, and the torsion spring 94 is configured to urge the lower front cover 87 forward with respect to the upper front cover 85. ing.

下前カバー87は、下端部に可撓性カバー96が突設されている。この可撓性カバー96は、下端部に複数のスリット97が設けられ、左右方向に分割されている。   The lower front cover 87 has a flexible cover 96 protruding from the lower end portion. The flexible cover 96 is provided with a plurality of slits 97 at the lower end and is divided in the left-right direction.

回転管12は、前後方向に沿って配設され、前端部に、前側へと拡開状に形成されて吸込室21の後部に連通する吸込風路99が接続されている。また、この回転管12は、下ケース16と上ケース17とより、周方向に回動可能に挟持されている。   The rotary tube 12 is disposed along the front-rear direction, and a suction air path 99 that is formed in a front-side opening shape and communicates with the rear portion of the suction chamber 21 is connected to the front end portion. The rotary tube 12 is sandwiched between the lower case 16 and the upper case 17 so as to be rotatable in the circumferential direction.

接続パイプ13は、回転管12の回転方向に対して直交する方向である前後方向へと回動可能に設けられている。   The connection pipe 13 is provided so as to be rotatable in the front-rear direction, which is a direction orthogonal to the rotation direction of the rotary tube 12.

次に、上記第１の実施の形態の動作を説明する。   Next, the operation of the first embodiment will be described.

まず、作業者は、掃除機本体１の本体吸込口３に、ホース体４、延長管８および吸込口体９を順次連通接続する。   First, the operator sequentially connects the hose body 4, the extension pipe 8, and the suction port body 9 to the main body suction port 3 of the cleaner body 1.

さらに、作業者が、掃除機本体１から電源コードを引き出して図示しないコンセントに接続した後、把持部６を把持して所定の設定ボタン７を操作すると、この設定ボタン７により設定された動作モードに応じて電動送風機２が駆動される。   Further, when the operator pulls out the power cord from the cleaner body 1 and connects it to an outlet (not shown), and then operates the predetermined setting button 7 by holding the holding portion 6, the operation mode set by the setting button 7 is set. Accordingly, the electric blower 2 is driven.

そして、作業者は、把持部６を把持して図８に示すように床面上で吸込口体９を前後に走行させ、吸込口15から塵埃を空気とともに吸い込み、延長管８およびホース体４を介して、本体吸込口３から集塵パックへと塵埃を運んで捕集する。   Then, the operator grips the gripping portion 6 and runs the suction port body 9 back and forth on the floor as shown in FIG. 8, sucks dust together with air from the suction port 15, and extends the extension pipe 8 and the hose body 4. Then, the dust is carried from the main body suction port 3 to the dust collecting pack and collected.

ここで、旋回輪48は、旋回輪本体57の旋回軸Ａに対して偏心したローラ58が床面に接地していることにより、この床面との接触抵抗などにより吸込口体９の吸込口本体11の走行方向に追従するように旋回する。   Here, the swirling wheel 48 has a suction port of the suction port body 9 due to contact resistance with the floor surface and the like because the roller 58 eccentric to the swivel axis A of the swirling wheel body 57 is in contact with the floor surface. It turns to follow the traveling direction of the main body 11.

この旋回に伴い、カム部68が本体軸部62に対して偏心旋回することで、このカム部68の外周部に転がり接触する検出ローラ74が、カム部68の外周部の凹凸形状に応じてアーム部72の先端側を揺動させ、このカム部68の凹凸形状に対応して検出スイッチ71がオンオフされる。   Along with this turning, the cam portion 68 turns eccentrically with respect to the main body shaft portion 62, so that the detection roller 74 that is in rolling contact with the outer peripheral portion of the cam portion 68 is in accordance with the uneven shape of the outer peripheral portion of the cam portion 68. The tip end side of the arm portion 72 is swung, and the detection switch 71 is turned on / off corresponding to the uneven shape of the cam portion 68.

すなわち、検出ローラ74が、カム部68の第１領域75の外周部に沿って転がり接触している場合には、アーム部72が検出スイッチ71側へと押し込まれず、付勢力により検出スイッチ71に対して離間された状態を維持し、本実施の形態では、検出スイッチ71がオフされ、制御手段28により、吸込口本体11が前進していると判断されるとともに、検出ローラ74が、カム部68の第２領域76の外周部に沿って転がり接触している場合には、アーム部72が付勢力に抗して押し込まれ、検出スイッチ71がオンされ、制御手段28により、吸込口本体11が後進していると判断される。   That is, when the detection roller 74 is in rolling contact with the outer peripheral portion of the first region 75 of the cam portion 68, the arm portion 72 is not pushed into the detection switch 71 side, and is applied to the detection switch 71 by the urging force. In this embodiment, the detection switch 71 is turned off, the control means 28 determines that the suction port body 11 is moving forward, and the detection roller 74 is connected to the cam portion. In the case of rolling contact along the outer peripheral portion of the second region 76 of 68, the arm portion 72 is pushed against the urging force, the detection switch 71 is turned on, and the suction port body 11 is turned on by the control means 28. Is determined to be moving backwards.

この結果、検出スイッチ71が、吸込口体９の走行方向に対応してオンオフされ、このオンオフの検出結果が制御手段28へと出力される。   As a result, the detection switch 71 is turned on / off corresponding to the traveling direction of the suction port body 9, and this on / off detection result is output to the control means 28.

オンオフの検出結果が入力された制御手段28は、モータ27への供給電力を制御して、このモータ27の駆動力がベルト39を介して伝達されることで、回転清掃体26が回転する。   The control means 28 to which the on / off detection result is input controls the power supplied to the motor 27 and the driving force of the motor 27 is transmitted via the belt 39, whereby the rotary cleaning body 26 rotates.

この回転に際しては、吸込口本体11の走行方向と所定の関係を有する方向、本実施の形態では、回転清掃体26を吸込口本体11の走行方向に対して逆方向、すなわち反対方向に沿って回転させる。換言すれば、検出スイッチ71がオフ状態の場合に、回転清掃体26を後方向へと回転させ、検出スイッチ71がオン状態の場合には、回転清掃体26を前方向へと回転させる。   During this rotation, the direction having a predetermined relationship with the traveling direction of the suction port body 11, in the present embodiment, the rotational cleaning body 26 is opposite to the traveling direction of the suction port body 11, that is, along the opposite direction. Rotate. In other words, when the detection switch 71 is off, the rotary cleaning body 26 is rotated backward, and when the detection switch 71 is on, the rotary cleaning body 26 is rotated forward.

ここで、ローラ58が旋回輪本体57の旋回軸Ａに対して偏心しているため、図１(a2)および図１(a3)に示すように吸込口本体11の走行方向を反転させた際に、図１(b2)および図１(b3)に示すように、旋回輪48の旋回開始からこの旋回輪48が所定角度旋回して検出手段67の検出スイッチ71のオンオフが切り換わって吸込口本体11の走行方向を検出するまでの時間分、制御手段28による回転清掃体26の回転方向の切り換えが遅れる。すなわち、吸込口本体11の走行方向の実際の切り換わったタイミングに対して、旋回輪48が旋回することで検出手段67が吸込口本体11の走行方向の切り換わりを検出したタイミングに遅れが生じる。   Here, since the roller 58 is eccentric with respect to the turning axis A of the turning wheel body 57, when the traveling direction of the suction inlet body 11 is reversed as shown in FIGS. 1 (a2) and 1 (a3). As shown in FIGS. 1 (b2) and 1 (b3), the turning wheel 48 turns a predetermined angle from the start of turning of the turning wheel 48, and the on / off of the detection switch 71 of the detecting means 67 is switched, and the inlet body The switching of the rotational direction of the rotary cleaning body 26 by the control means 28 is delayed by the time until the eleven travel directions are detected. That is, with respect to the timing at which the suction port body 11 is switched in the traveling direction, a delay occurs in the timing at which the detection means 67 detects the switching of the suction port body 11 in the traveling direction by turning the swivel wheel 48. .

このため、この遅れた時間の間だけ、回転清掃体26が吸込口本体11の走行方向に沿う回転を維持するから、制御手段28などで複雑な制御をすることなく吸込口本体11の走行方向と回転清掃体26の回転方向とに複数の関係を持たせることが可能となり、掃除性を向上できる。   For this reason, since the rotary cleaning body 26 maintains the rotation along the traveling direction of the suction port body 11 only during this delayed time, the traveling direction of the suction port body 11 without complicated control by the control means 28 or the like. And the rotational direction of the rotary cleaning body 26 can have a plurality of relationships, and the cleaning performance can be improved.

具体的に、例えば図１(a1)に示すように、吸込口本体11の前進時には後方向へ回転していた回転清掃体26が、図１(a2)および図１(a3)に示すように吸込口本体11を前進から後進へと切り換えた際に、この切り換えに追従して図１(b1)ないし図１(b3)に示すように旋回輪48が旋回して検出手段67が走行方向の切り換わりを検出するまでの間だけは、図１(a2)に示すように、吸込口本体11と回転清掃体26との回転方向との関係が通常状態と逆の関係、すなわち吸込口本体11の走行方向である後方向と同じ後方向への回転を維持するので、この回転清掃体26の回転により吸込口体９の移動を補助できる。   Specifically, as shown in FIG. 1 (a1), for example, the rotary cleaning body 26 that has been rotated backward when the suction port body 11 moves forward is shown in FIGS. 1 (a2) and 1 (a3). When the suction port main body 11 is switched from forward to reverse, the swivel wheel 48 is swung as shown in FIG. 1 (b1) to FIG. Only until the switching is detected, as shown in FIG. 1 (a2), the relationship between the rotation direction of the suction port body 11 and the rotary cleaning body 26 is opposite to the normal state, that is, the suction port body 11 Therefore, the rotation of the rotary cleaning body 26 can assist the movement of the suction port body 9.

さらに、カム部68の形状と、このカム部68の外周部への検出ローラ74の転がり接触による検出スイッチ71のオンオフとにより旋回輪48の旋回角度を検出するため、複数のセンサを旋回輪48の周囲に配置してこれらセンサにより旋回輪48の旋回角度を検出するなどの場合と異なり、３６０°全ての任意の旋回角度に対して検出手段67が連続的に対応できる。   Further, in order to detect the turning angle of the turning wheel 48 based on the shape of the cam part 68 and the on / off of the detection switch 71 due to the rolling contact of the detection roller 74 to the outer periphery of the cam part 68, a plurality of sensors are connected to the turning wheel 48. Unlike the case where the turning angle of the turning wheel 48 is detected by these sensors arranged around the detector, the detecting means 67 can continuously cope with any turning angle of 360 °.

また、検出スイッチ71のアーム部72は、カム部68に対して傾斜して突出しているから、このカム部68の回転方向に応じて、揺動しやすい場合と揺動しにくい場合とがある。このため、ギア部78がローラ本体77に対して軸方向の他端側に偏位させることで、吸込口本体11の走行方向を切り換えた際に、旋回輪48を決まった方向に回動しやすくし、この回動方向を、アーム部72が揺動しやすい方向とすることで、検出スイッチ71のオンオフを旋回輪48の旋回によって確実に切り換えできる。   Further, since the arm portion 72 of the detection switch 71 protrudes in an inclined manner with respect to the cam portion 68, there are cases where it is easy to swing or difficult to swing depending on the rotation direction of the cam portion 68. . For this reason, when the traveling direction of the suction port body 11 is switched by shifting the gear part 78 to the other end side in the axial direction with respect to the roller body 77, the turning wheel 48 is rotated in a predetermined direction. The rotation direction is set to be a direction in which the arm portion 72 easily swings, so that the on / off of the detection switch 71 can be reliably switched by turning the turning wheel 48.

しかも、ギア部78をローラ本体77の外周面の一部に形成するため、ローラ本体77の外周面全体が床面と接触する場合と比較して、ローラ58と床面との接触跡が幅狭となって、この接触跡が残りにくい。   Moreover, since the gear part 78 is formed on a part of the outer peripheral surface of the roller body 77, the contact mark between the roller 58 and the floor surface is wider than when the entire outer peripheral surface of the roller body 77 is in contact with the floor surface. It becomes narrow and this contact mark is hard to remain.

さらに、接触部をギア状に突設した複数のギア部78とすることで、ローラ本体77が可撓変形しても、ギア部78が床面に対して確実に噛み、旋回輪48を確実に旋回させることができる。   Furthermore, by making the contact portions into a plurality of gear portions 78 projecting in a gear shape, even if the roller main body 77 is flexibly deformed, the gear portion 78 reliably bites against the floor surface, and the swivel wheel 48 is reliably secured. Can be swiveled.

そして、このような吸込口体９を備えることにより、電気掃除機の使い勝手を向上できる。   And the convenience of a vacuum cleaner can be improved by providing such a suction inlet 9.

次に、第２の実施の形態を図１０を参照して説明する。なお、上記第１の実施の形態と同様の構成および作用については、同一符号を付してその説明を省略する。   Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

この第２の実施の形態は、図１０(a1)ないし図１０(a3)、および、図１０(b1)ないし図１０(b3)に示すように、制御手段28が、検出手段67により検出した吸込口本体11の走行方向に対して、回転清掃体26を順方向に回転させるものである。すなわち、制御手段28は、検出スイッチ71がオフ状態の場合に、回転清掃体26を前方向へと回転させ、検出スイッチ71がオン状態の場合には、回転清掃体26を後方向へと回転させる。   In the second embodiment, as shown in FIGS. 10 (a1) to 10 (a3) and FIGS. 10 (b1) to 10 (b3), the control means 28 detects the detection means 67. The rotary cleaning body 26 is rotated in the forward direction with respect to the traveling direction of the suction inlet body 11. That is, the control means 28 rotates the rotary cleaning body 26 forward when the detection switch 71 is off, and rotates the rotary cleaning body 26 rearward when the detection switch 71 is on. Let

そして、この第２の実施の形態では、ローラ58が旋回輪本体57の旋回軸Ａに対して偏心しているため、図１０(a2)および図１０(a3)に示すように吸込口本体11の走行方向を反転させた際に、図１０(b2)および図１０(b3)に示すように、旋回輪48が所定角度旋回して検出手段67の検出スイッチ71のオンオフが切り換わって吸込口本体11の走行方向を検出するまでの時間分、制御手段28による回転清掃体26の回転方向の切り換えが遅れる。   In the second embodiment, since the roller 58 is eccentric with respect to the turning axis A of the turning wheel body 57, as shown in FIGS. 10 (a2) and 10 (a3), When the traveling direction is reversed, as shown in FIGS. 10 (b2) and 10 (b3), the turning wheel 48 turns by a predetermined angle and the on / off of the detection switch 71 of the detecting means 67 is switched, and the suction port body The switching of the rotational direction of the rotary cleaning body 26 by the control means 28 is delayed by the time until the eleven travel directions are detected.

このため、この遅れた時間の間だけ、回転清掃体26が吸込口本体11の走行方向と反対方向に沿う回転を維持するから、制御手段28などで複雑な制御をすることなく吸込口本体11の走行方向と回転清掃体26の回転方向とに複数の関係を持たせることが可能となり、掃除性を向上できる。   For this reason, since the rotary cleaning body 26 maintains the rotation along the direction opposite to the traveling direction of the suction port body 11 only during this delayed time, the suction port body 11 is not subjected to complicated control by the control means 28 or the like. It is possible to have a plurality of relationships between the traveling direction of the motor and the rotational direction of the rotary cleaning body 26, thereby improving the cleaning performance.

具体的に、例えば図１０(a1)に示すように、吸込口本体11の前進時には前方向へ回転していた回転清掃体26が、図１０(a2)および図１０(a3)に示すように吸込口本体11を前進から後進へと切り換えた際に、この切り換えに追従して図１０(b1)ないし図１０(b3)に示すように旋回輪48が旋回して検出手段67が走行方向の切り換わりを検出するまでの間だけは、図１０(a2)に示すように、吸込口本体11と回転清掃体26との回転方向との関係が通常状態と逆の関係、すなわち吸込口本体11の走行方向である後方向と反対の前方向への回転を維持するので、この回転清掃体26の回転により床面からの塵埃の掻き取り効果を向上できる。   Specifically, for example, as shown in FIG. 10 (a1), the rotary cleaning body 26 that has been rotated forward when the suction port body 11 moves forward is shown in FIGS. 10 (a2) and 10 (a3). When the suction port main body 11 is switched from forward to reverse, the turning wheel 48 turns as shown in FIG. 10 (b1) to FIG. 10 (b3) following the switching, and the detecting means 67 changes in the traveling direction. Only until the switching is detected, as shown in FIG. 10 (a2), the relationship between the rotation direction of the suction port body 11 and the rotary cleaning body 26 is opposite to the normal state, that is, the suction port body 11. Therefore, the rotation of the rotary cleaning body 26 can improve the dust scraping effect from the floor surface.

なお、上記各実施の形態において、検出スイッチ71は、オンオフが逆になるもの、すなわち、アーム部72が突出した状態でオン、アーム部72が押し込まれた状態でオフとなるものであっても、制御手段28などの各種回路を対応させることで上記各実施の形態と同様に構成できる。   In each of the embodiments described above, the detection switch 71 may be one that is turned on and off in reverse, that is, one that is turned on when the arm portion 72 is projected and turned off when the arm portion 72 is pushed. By making various circuits such as the control means 28 correspond to each other, it can be configured in the same manner as in the above embodiments.

また、吸込口本体11において、前側吸込口18を含む前カバー19周辺の構成は、上記構成に限定されるものではなく、例えばこれら前側吸込口18および前カバー19などを設けない吸込口体９でも、同様の作用効果を奏することができる。   Further, in the suction port main body 11, the configuration around the front cover 19 including the front suction port 18 is not limited to the above configuration. For example, the suction port body 9 in which the front suction port 18 and the front cover 19 are not provided. However, similar effects can be achieved.

さらに、吸込口本体11の走行方向を、この走行方向に対応する旋回輪48の旋回角度に応じて検出できれば、検出手段67およびカム部68の構成および形状などは、上記構成に限定されるものではない。
また、カム部68の各領域75，76の各中心角は、検出したい吸込口本体11の走行方向の角度などに応じて任意に設定できる。 Furthermore, if the traveling direction of the suction inlet body 11 can be detected according to the turning angle of the swivel wheel 48 corresponding to this traveling direction, the configurations and shapes of the detection means 67 and the cam portion 68 are limited to the above-described configurations. Not .
Further, the central angles of the regions 75 and 76 of the cam portion 68 can be arbitrarily set according to the angle in the traveling direction of the suction port body 11 to be detected.

さらに、吸込口本体11の走行方向と所定の関係を有する所定方向に回転方向を制御するのは、回転清掃体26に限らず、駆動輪などの回転体であれば同様の作用効果を奏することができる。   Furthermore, it is not limited to the rotary cleaning body 26 that controls the rotation direction in a predetermined direction having a predetermined relationship with the traveling direction of the suction inlet body 11, and the same effects can be achieved as long as it is a rotary body such as a drive wheel. Can do.

さらに、電気掃除機の細部は、上記構成に限定されるものではなく、電気掃除機としては、キャニスタ型に限らず、例えば自走式の電気掃除機などでもよく、また、例えば吸込口体９が掃除機本体１の下面に直接形成されたアップライト型、あるいはハンディ型などであっても対応させて用いることができる。   Furthermore, the details of the vacuum cleaner are not limited to the above configuration, and the vacuum cleaner is not limited to the canister type, and may be, for example, a self-propelled vacuum cleaner or the like. However, even an upright type or a handy type directly formed on the lower surface of the cleaner body 1 can be used correspondingly.
