Supply line.

接点群５１は、電極環群４７の一方の端部よりでありかつ回転管３８の周方向に見て略同じ位相に配置された複数の接点５１ａ、５１ｂ、５１ｃからなる第一接点群７１と、電極環群４７の他方の端部よりでありかつ回転管３８の周方向に見て第一接点群７１の略逆位相に配置された複数の接点５１ｄ、５１ｅからなる第二接点群７２と、を備える。   The contact group 51 includes a first contact group 71 including a plurality of contacts 51 a, 51 b, 51 c that are arranged at substantially the same phase when viewed in the circumferential direction of the rotary tube 38 from one end of the electrode ring group 47.

接点５１ａ、５１ｂ、５１ｃ、５１ｄ、５１ｅは、孔部３６ａの奥側から順に、通過導線４９ａに電気的に接続された表示信号用接点（接点５１ａ）、操作部２４に電気的に接続された操作信号用接点（接点５１ｂ）、通過導線４９ｂおよび操作部２４の接地線に電気的に接続された信号用共通接地接点（接点５１ｃ）、通過導線４９ｃに電気的に接続された電力供給用接地接点（接点５１ｄ）、通過導線４９ｄに電気的に接続された電力供給用接点（接点５１ｅ）である。接点５１ａは電極環４７ａに電気的に接続され、接点５１ｂは電極環４７ｂに電気的に接続され、接点５１ｅは電極環４７ｄに電気的に接続される。接点５１ｃおよび接点５１ｄは、共通の電極環４７ｃに電気的に接続される。   The contact points 51a, 51b, 51c, 51d, and 51e are electrically connected to the display signal contact point (contact point 51a) and the operation unit 24, which are electrically connected to the passing lead wire 49a in this order from the back side of the hole 36a. Common contact point for signal (contact 51c) electrically connected to the operation signal contact (contact 51b), the passing conductor 49b and the ground wire of the operation section 24, and the power supply ground electrically connected to the passing conductor 49c A contact (contact 51d) is a power supply contact (contact 51e) electrically connected to the passing conductor 49d.

The contact group 51 is drawn away from 47.) Since the contacts 51a, 51b, 51c, 51d, and 51e all have a common structure, the description of the other contacts 51b, 43, 44, and 45 is omitted.

そして、把持部２３、第一接点群７１および第二接点群７２は、回転管３８の回転中心線を含んだ略同一面上に配置されるとともに、回転管３８の周方向に見て第一接点群７１は把持部２３と略同位相に配置され、かつ回転管３８の中心線方向に見て第一接点群７１は第二接点群７２よりも把持部２３から遠い側に配置される。   The grip portion 23, the first contact group 71, and the second contact group 72 are arranged on substantially the same plane including the rotation center line of the rotary tube 38, and are first viewed in the circumferential direction of the rotary tube 38. The contact group 71 is arranged in substantially the same phase as the grip part 23, and the first contact group 71 is arranged farther from the grip part 23 than the second contact group 72 when viewed in the center line direction of the rotary tube 38.

また、第一接点群７１は第一接点台６７に設けられ、第二接点群７２は第二接点台６８に設けられる。したがって、手元操作管２２は、第一接点台６７および第二接点台６８を外郭３９に組み付けることによって回転管３８の抜け止めと接点群５１と電極環群４７との電気的な接続を同時に行う。   The first contact group 71 is provided on the first contact base 67, and the second contact group 72 is provided on the second contact base 68. Therefore, the hand control tube 22 is configured to prevent the rotary tube 38 from being detached and to electrically connect the contact group 51 and the electrode ring group 47 by assembling the first contact stand 67 and the second contact stand 68 to the outer shell 39. .

図６は、本発明の実施形態に係る電気掃除機の管部を示した側面図である。   FIG. 6 is a side view showing a tube portion of the electric vacuum cleaner according to the embodiment of the present invention.

図４および図６に示すように、第一直管部３５に延長管２５を接続するとともに延長管２５の下端に吸込口体２６を接続して回転管３８が下方になるように第一把持部４１を持ち上げて手元操作管２２の握り高さＨを適宜に設定したとき、集塵ホース２１は、手元操作管２２から掃除機本体２に向かって垂れ下がるように延びる。   As shown in FIGS. 4 and 6, the extension pipe 25 is connected to the first straight pipe portion 35 and the suction port body 26 is connected to the lower end of the extension pipe 25 so that the rotary pipe 38 faces downward. When the portion 41 is lifted and the grip height H of the hand operation tube 22 is set appropriately, the dust collecting hose 21 extends from the hand operation tube 22 toward the cleaner body 2.

このように、第一把持部４１を持ち上げると、集塵ホース２１の自重（手元操作管２２から掃除機本体２に向かって垂れ下がるように延びたときの自重）や移動時の慣性力は、回転管３８のジャーナル部５５、５６から手元操作管２２のラジアル軸受６２、６３に伝わる。この力は、回転管３８をジャーナル部５５、ラジアル軸受６２において上方向、ジャーナル部５６、ラジアル軸受６３において下方向に働く偶力Ｍ（図６中、実線矢Ｍ）を生じる。したがって、第一接点群７１および第二接点群７２は、集塵ホース２１から回転管３８に加えられる偶力Ｍによって接点５１ａ、５１ｂ、５１ｅのそれぞれが電極環４７ａ、４７ｂ、４７ｃに押圧されるよう配置されている。   As described above, when the first gripping portion 41 is lifted, the weight of the dust collecting hose 21 (the weight of the dust collecting hose 21 extending so as to hang down from the hand operation tube 22 toward the cleaner body 2) and the inertial force during movement are rotated. It is transmitted from the journal portions 55 and 56 of the pipe 38 to the radial bearings 62 and 63 of the hand operating pipe 22. This force generates a couple M (solid arrow M in FIG. 6) that acts on the rotary tube 38 upward in the journal portion 55 and radial bearing 62 and downward in the journal portion 56 and radial bearing 63. Accordingly, in the first contact group 71 and the second contact group 72, the contacts 51a, 51b, 51e are pressed against the electrode rings 47a, 47b, 47c by the couple M applied from the dust collecting hose 21 to the rotary tube 38, respectively. It is arranged as follows.

また、一般に、長期間の使用にともなって手元操作管２２の孔部３６ａと回転管３８とのガタが拡大してくるが、このガタは、もっぱら孔部３６ａの開口付近で大きくなる。すなわち、手元操作管２２は、孔部３６ａの開口に近いジャーナル部５６、ラジアル軸受６３において長期間の使用にともなうガタを増大させる。そこで、本実施形態に係る手元操作管２２は、孔部３６ａの開口から遠く比較的にガタが小さいままのジャーナル部５５、ラジアル軸受６２側に第一接点群７１を配置し、孔部３６ａの開口に近く比較的にガタが大きくなるジャーナル部５６、ラジアル軸受６３側に第二接点群７２を配置する。   In general, the backlash between the hole portion 36a of the hand operating tube 22 and the rotary tube 38 increases with long-term use, but this backlash increases mainly in the vicinity of the opening of the hole portion 36a. That is, the hand control tube 22 increases the backlash associated with long-term use in the journal portion 56 and the radial bearing 63 close to the opening of the hole 36a. Therefore, in the hand control tube 22 according to the present embodiment, the first contact group 71 is disposed on the side of the journal portion 55 and the radial bearing 62 that are far from the opening of the hole portion 36a and remain relatively small, and the hole portion 36a The second contact group 72 is disposed on the journal portion 56 and the radial bearing 63 side where the play is relatively large near the opening.

これによって、表示信号用接点（接点５１ａ）、操作信号用接点（接点５１ｂ）および信号用共通接地接点（接点５１ｃ）は電極環４７ａ、４７ｂ、４７ｃから離間し難い構造を採用できる。表示信号用接点（接点５１ａ）や操作信号用接点（接点５１ｂ）が離間すると、誤表示や誤操作入力が起こり、電気掃除機１の使用者に不快感を与える虞があるところ、本実施形態に係る手元操作管２２は、これを回避できる。   Accordingly, it is possible to adopt a structure in which the display signal contact (contact 51a), the operation signal contact (contact 51b), and the signal common ground contact (contact 51c) are difficult to be separated from the electrode rings 47a, 47b, 47c. If the display signal contact (contact 51a) or the operation signal contact (contact 51b) is separated, erroneous display or erroneous operation input may occur, which may cause discomfort to the user of the vacuum cleaner 1. Such a hand control tube 22 can avoid this.

また、第二接点群７２（すなわち、接点５１ｄまたは接点５１ｅ）は、比較的にガタが大きくなり電極環４７ｃ、４７ｄから離間しやすくなることが懸念されるが、仮に離間による電力供給の瞬断が起こって回転清掃体３１を駆動させる電動機３２の出力が一時的に低下しても集塵ホース２１の自重等によって速やかに接点５１ｄ、５１ｅおよび電極環４７ｃ、４７ｄの電気的な接続を回復させて電動機３２の出力を回復させる。   In addition, there is a concern that the second contact group 72 (that is, the contact 51d or the contact 51e) is relatively large and easily separated from the electrode rings 47c and 47d. Even if the output of the electric motor 32 that drives the rotary cleaning body 31 temporarily decreases, the electrical connection between the contacts 51d and 51e and the electrode rings 47c and 47d is quickly restored by the dead weight of the dust collecting hose 21 or the like. Thus, the output of the electric motor 32 is recovered.

このように構成された本実施形態に係る電気掃除機１および電気掃除機用ホース２７によれば、集塵ホース２１の自重によって作用する力を利用して電極環４７ａ、４７ｂ、４７ｃ、４７ｄを接点５１ａ、５１ｂ、５１ｃ、５１ｄ、５１ｅに押圧させて相互の導通不良を抑制できる。   According to the vacuum cleaner 1 and the vacuum cleaner hose 27 according to the present embodiment configured as described above, the electrode rings 47a, 47b, 47c, and 47d are connected to each other by using the force acting by the weight of the dust collecting hose 21. The contact points 51a, 51b, 51c, 51d and 51e can be pressed to suppress mutual conduction failure.

また、本実施形態に係る電気掃除機１および電気掃除機用ホース２７によれば、長期間の使用によっても比較的にガタの少ない部分（手元操作管２２の孔部３６ａの奥側および孔部３６ａに挿入された回転管３８の先端側）に表示信号用接点（接点５１ａ）および操作信号用接点（接点５１ｂ）を含んだ第一接点群７１を配置できるので、誤表示や誤操作入力を生じさせるような導通不良を長期に渡って抑制できる。   Moreover, according to the vacuum cleaner 1 and the vacuum cleaner hose 27 according to the present embodiment, a portion with relatively little play even after long-term use (the back side and the hole of the hole 36a of the hand operation tube 22). Since the first contact group 71 including the display signal contact (contact 51a) and the operation signal contact (contact 51b) can be disposed on the tip side of the rotary tube 38 inserted in 36a, erroneous display or erroneous operation input occurs. Such poor conduction can be suppressed over a long period of time.

さらに、本実施形態に係る電気掃除機１および電気掃除機用ホース２７によれば、長期間の使用によって比較的にガタの大きくなる部分（手元操作管２２の孔部３６ａの開口側および孔部３６ａに挿入された回転管３８の根本側）に電力供給用接点（接点５１ｅ）を含んだ第二接点群７２を配置できるので、この接点群５１の全てを長期間の使用によっても比較的にガタの少ない部分（手元操作管２２の孔部３６ａの奥側および孔部３６ａに挿入された回転管３８の先端側）に配置する場合と比較して手元操作管２２および回転管３８を小型に構成できる。   Furthermore, according to the vacuum cleaner 1 and the vacuum cleaner hose 27 according to the present embodiment, the portion that becomes relatively loose due to long-term use (the opening side and the hole portion of the hole portion 36a of the hand operation tube 22). Since the second contact group 72 including the contact point for power supply (contact point 51e) can be arranged on the base side of the rotary tube 38 inserted in 36a, all of the contact group 51 can be relatively used even after long-term use. Compared with the case where it is arranged in a portion with less play (the back side of the hole 36a of the hand operating tube 22 and the tip side of the rotating tube 38 inserted into the hole 36a), the hand operating tube 22 and the rotating tube 38 are made smaller. Can be configured.

さらにまた、本実施形態に係る電気掃除機１および電気掃除機用ホース２７によれば、長期間の使用によって比較的にガタの大きくなる部分（手元操作管２２の孔部３６ａの開口側および孔部３６ａに挿入された回転管３８の根本側）に電力供給用接点（接点５１ｅ）を含んだ第二接点群７２を配置できるので、管部３の通常の使用する場合（例えば、被掃除面上で吸込口体２６を前後走行させる場合）には集塵ホース２１の自重によって電源供給が遮断されるような導通不良を抑制できる。また仮に、第二接点群７２が電極環群４７から離間してしまい導通不良を生じて回転清掃体３１の回転力が一時的に低下しても、電気掃除機１および電気掃除機用ホース２７によれば、集塵ホース２１の自重によって速やかに導通を回復させて回転清掃体の回転力を回復できる。   Furthermore, according to the vacuum cleaner 1 and the vacuum cleaner hose 27 according to the present embodiment, the portion that becomes relatively loose due to long-term use (the opening side and the hole of the hole 36a of the hand operation tube 22). Since the second contact group 72 including the power supply contact (contact 51e) can be disposed on the base side of the rotary tube 38 inserted in the portion 36a, when the tube portion 3 is used normally (for example, the surface to be cleaned) When the suction port body 26 is moved back and forth above, it is possible to suppress a conduction failure such that the power supply is interrupted by the weight of the dust collecting hose 21. Further, even if the second contact group 72 is separated from the electrode ring group 47 and a conduction failure occurs, and the rotational force of the rotary cleaning body 31 is temporarily reduced, the vacuum cleaner 1 and the vacuum cleaner hose 27 are disposed. According to the above, it is possible to quickly restore conduction by the dead weight of the dust collecting hose 21 and to restore the rotational force of the rotary cleaning body.

したがって本発明の実施形態に係る電気掃除機１および電気掃除機用ホース２７によれば、集塵ホース２１の捩れを防止する回転管３８を備えつつ、長期間の使用に渡って導通不良を抑制できる。   Therefore, according to the vacuum cleaner 1 and the vacuum cleaner hose 27 according to the embodiment of the present invention, the rotating tube 38 that prevents the dust collecting hose 21 from being twisted is provided, and poor conduction is suppressed over a long period of use. it can.
