Description

本発明は、電気掃除機に関するものである。   The present invention relates to a vacuum cleaner.

従来の電気掃除機は、集塵室内に集塵袋を装着し、電動送風機を運転させることにより集塵袋内に塵埃を集塵するようにしている。集塵袋内に塵埃が蓄積してくると集塵袋は徐々に目詰まりを始めて、しだいに吸引力が低下してくる。   In a conventional vacuum cleaner, a dust collection bag is mounted in a dust collection chamber, and the electric blower is operated to collect dust in the dust collection bag. When dust accumulates in the dust bag, the dust bag gradually begins to clog, and the suction force gradually decreases.

このとき、集塵袋の後面や下面に外側から除塵手段による除塵振動を加えて集塵袋の内面に付着する塵埃を振り落として吸引力の回復を図るようにしている（例えば特許文献１）。   At this time, dust suction vibration is applied to the rear surface and lower surface of the dust bag from the outside, and dust adhering to the inner surface of the dust bag is shaken off to recover the suction force (for example, Patent Document 1). .

しかしながら、除塵手段による除塵により、集塵袋から外側に抜けた細塵は集塵室の内底部に溜まる。この細塵の除去は、除塵手段が邪魔して掃除がし難い。   However, fine dust that has flowed out of the dust collection bag due to dust removal by the dust removal means accumulates in the inner bottom of the dust collection chamber. The removal of this fine dust is difficult to clean because the dust removing means interferes.

本発明は、上記の問題に鑑み、集塵室の内底部の掃除がし易い電気掃除機を提供することを目的とする。   An object of this invention is to provide the vacuum cleaner which is easy to clean the inner bottom part of a dust collection chamber in view of said problem.

本発明は、電動送風機と、この電動送風機の隣りに配置されるコードリールと、電動送風機の上流側に配置される集塵袋と、この集塵袋を内置する集塵室と、集塵袋の内面に付着する塵埃を振るい落とす除塵手段とを有する電気掃除機において、除塵手段は、集塵室内に置かれ、かつ集塵袋の下部側と後部側に除塵振動を伝える除塵部材と、コードリールに駆動され、かつ除塵部材に振動動作を起こさせる除塵回転体とを有し、除塵部材は、集塵袋の後部側に当接する縦置除塵体と、集塵袋の下部側と当接する横置除塵体とを有し、縦置除塵体の下端側と横置除塵体の後端側が回動自在に結合されていることを特徴とする。   The present invention relates to an electric blower, a cord reel arranged next to the electric blower, a dust collection bag arranged upstream of the electric blower, a dust collection chamber in which the dust collection bag is placed, and a dust collection bag In a vacuum cleaner having dust removing means for shaking off dust adhering to the inner surface of the dust collecting means, the dust removing means is placed in the dust collecting chamber, and a dust removing member that transmits dust removing vibration to the lower side and the rear side of the dust collecting bag, and a cord A dust removal rotating body that is driven by the reel and causes the dust removal member to vibrate, and the dust removal member contacts the vertical dust removal body that contacts the rear side of the dust collection bag and the lower side of the dust collection bag It has a horizontal dust remover, and the lower end side of the vertical dust remover and the rear end side of the horizontal dust remover are rotatably coupled.

本発明によれば、横置除塵体を立てかけるように折り畳まれるので、集塵室の内底部の掃除が容易にできる。   According to the present invention, since the horizontal dust removing body is folded up so as to stand, cleaning of the inner bottom portion of the dust collecting chamber can be facilitated.

本発明の実施例について、図を引用して説明する。   Embodiments of the present invention will be described with reference to the drawings.

まず、図1〜図５に沿い、表示について説明する。   First, the display will be described with reference to FIGS.

図１に示すように電気掃除機の掃除機本体ケース１は、後部側に走行用の車輪２を有する。掃除機本体ケース１の前側下部には、走行用のキャスター（図示せず）が備わる。   As shown in FIG. 1, the vacuum cleaner main body case 1 of the electric vacuum cleaner has traveling wheels 2 on the rear side. The lower part of the front side of the vacuum cleaner body case 1 is provided with a traveling caster (not shown).

掃除機本体ケース１の前側内部には、集塵室３が設けられる。この集塵室３には、紙袋を含む集塵袋が取り外し自在に内置される。ホース差込口４は掃除機本体ケース１の前側に設けられ、集塵室３に連通する。   A dust collection chamber 3 is provided inside the front side of the cleaner body case 1. A dust collection bag including a paper bag is detachably placed in the dust collection chamber 3. The hose insertion port 4 is provided on the front side of the cleaner body case 1 and communicates with the dust collection chamber 3.

掃除機本体ケース１の後部は後部室を有し、電動送風機やコードリールが内置される。   The rear portion of the vacuum cleaner main body case 1 has a rear chamber, and an electric blower and a cord reel are placed therein.

集塵室３の上面には、集塵袋が出し入れされる開口部を有し、この開口部を開閉自在に覆う蓋体５が備わる。蓋体５は掃除機本体ケース１に回動自在に支持される。   On the upper surface of the dust collection chamber 3, there is provided a lid 5 that has an opening through which a dust collection bag is taken in and out and covers the opening so as to be freely opened and closed. The lid 5 is rotatably supported by the cleaner body case 1.

蓋体５は、図１に示すように表示部６を有する。表示部６は、図２、図３、図４に示すように、蓋体５の内側に設けた導光管７が光ることにより表示される。   The lid 5 has a display unit 6 as shown in FIG. As shown in FIGS. 2, 3, and 4, the display unit 6 is displayed when the light guide tube 7 provided inside the lid 5 shines.

図５に示す表示制御箱８は、掃除機本体ケース１の後部室の上側に設けられる。表示制御箱８は、図４に示すように、発光ダイオード９、制御基板１０、電源部２０を有する。   The display control box 8 shown in FIG. 5 is provided above the rear chamber of the cleaner body case 1. As shown in FIG. 4, the display control box 8 includes a light emitting diode 9, a control board 10, and a power supply unit 20.

表示制御箱８は、前面に二つの投光孔２１を有する。二つの発光ダイオード９が発する光は、その投光孔２１から導光管７に入って表示部６の表示が行なわれる。   The display control box 8 has two light emitting holes 21 on the front surface. The light emitted from the two light emitting diodes 9 enters the light guide tube 7 through the light projection hole 21 and is displayed on the display unit 6.

この表示は、例えば、集塵袋の集塵量を示すインジケータとして利用される。集塵袋の集塵量を圧力センサ等で検知して発光ダイオード９を発光させる。   This display is used, for example, as an indicator showing the amount of dust collected in the dust bag. The amount of dust collected in the dust bag is detected by a pressure sensor or the like to cause the light emitting diode 9 to emit light.

例えば、集塵量が中程度のときは、発光ダイオード９を一つだけ発光させ、満杯になったら二つとも発光させることにより、集塵量が報知される。   For example, when the amount of dust collection is medium, only one light-emitting diode 9 emits light, and when it is full, both emit light to notify the dust collection amount.

本発明の実施例では、白色を発する発光ダイオード９を用い、投光孔２１と導光管７の間にカラーフィルタ２２を設けた。このカラーフィルタ２２の色を選択することにより、表示に任意の色を選ぶことができる。   In the embodiment of the present invention, the white light emitting diode 9 is used, and the color filter 22 is provided between the light projection hole 21 and the light guide tube 7. By selecting the color of the color filter 22, an arbitrary color can be selected for display.

白色の発光ダイオードは、カラー発光ダイオードに比べて安価である。白色の発光ダイオードと、カラーフィルタを組み合わせることにより、安価なカラー表示を提供することができる。   White light emitting diodes are less expensive than color light emitting diodes. By combining a white light emitting diode and a color filter, an inexpensive color display can be provided.

なお、投光孔２１と導光管７の間には、蓋体５に仕切壁２３が存在する。仕切壁２３に光を通す光通過孔２４を形成し、この光通過孔２４のところにカラーフィルタ２２を設けた。カラーフィルタ２２は表示制御箱８に対面する側に位置しているが、導光管７に対面する側に配置することも可能である。   A partition wall 23 exists in the lid 5 between the light projection hole 21 and the light guide tube 7. A light passage hole 24 through which light passes is formed in the partition wall 23, and a color filter 22 is provided at the light passage hole 24. Although the color filter 22 is located on the side facing the display control box 8, it can be arranged on the side facing the light guide tube 7.

次に除塵関連に関して説明する。   Next, the dust removal related will be described.

図６、図２２に示すように、掃除機本体ケース１の集塵室３には、集塵袋２５が内置される。この集塵袋２５は、使い捨ての集塵袋ないし再利用可能な布集塵袋を含む。   As shown in FIGS. 6 and 22, a dust collection bag 25 is placed in the dust collection chamber 3 of the cleaner body case 1. The dust bag 25 includes a disposable dust bag or a reusable cloth dust bag.

掃除機本体ケース１は、集塵室３の後側に後部室を有する。この後部室は、電動送風機２６、コードリール２７を内置する。   The vacuum cleaner body case 1 has a rear chamber on the rear side of the dust collection chamber 3. This rear chamber houses an electric blower 26 and a cord reel 27.

電動送風機２６は、送風部（ファン）と電動機を有する。送風部が前側、電動機が後側になるように置かれる。コードリール２７は、電動送風機２６の隣りに並ぶように置かれる。電動送風機２６には、コードリール２７を介して電力が供給される。   The electric blower 26 has a blower (fan) and an electric motor. The blower is placed on the front side and the electric motor on the rear side. The cord reel 27 is placed next to the electric blower 26. Electric power is supplied to the electric blower 26 via the cord reel 27.

集塵袋の除塵は、除塵手段で行なわれる。除塵手段は、除塵部材とコードリールに駆動され、かつ前記除塵部材に振動動作を起こさせる除塵回転体とを有する。   The dust collection bag is dust-removed by dust removing means. The dust removing means includes a dust removing member and a dust removing rotating body that is driven by the cord reel and causes the dust removing member to vibrate.

除塵部材２８は、集塵室３に備えられる。集塵室３に置かれる集塵袋２５は、除塵部材２８で、振動させられて内部に付着する塵埃が振るい落とされる。   The dust removing member 28 is provided in the dust collection chamber 3. The dust collection bag 25 placed in the dust collection chamber 3 is vibrated by the dust removing member 28 and the dust attached to the inside is shaken off.

除塵駆動伝達ユニット２９（図２３の（ａ））は、掃除機本体ケース１の内底部に備えられる。除塵駆動伝達ユニット２９は、除塵回転体３０と、伝達歯車４０を有する。この伝達歯車４０は、コードリール２７の駆動歯車４１に噛み合う。   The dust removal drive transmission unit 29 (FIG. 23A) is provided on the inner bottom of the cleaner body case 1. The dust removal drive transmission unit 29 includes a dust removal rotary body 30 and a transmission gear 40. The transmission gear 40 meshes with the drive gear 41 of the cord reel 27.

コードリール２７の回転で、駆動歯車４１、伝達歯車４０を介して除塵駆動伝達ユニット２９の除塵回転体３０に回転が伝わる。除塵回転体３０の回転により、除塵部材２８は振動させられ、集塵袋２５内の除塵が行なわれる。   The rotation of the cord reel 27 is transmitted to the dust removal rotary body 30 of the dust removal drive transmission unit 29 via the drive gear 41 and the transmission gear 40. The dust removal member 28 is vibrated by the rotation of the dust removal rotating body 30, and the dust in the dust collection bag 25 is removed.

除塵部材について、図７〜図１９を引用して更に詳しく述べる。   The dust removing member will be described in more detail with reference to FIGS.

除塵部材２８は、縦置除塵体４２と、横置除塵体４３とを有する。縦置除塵体４２の下端と、横置除塵体４３の後端は支軸４４により回動自在に結合されている。縦置除塵体４２と横置除塵体４３は、折り畳まれた０度（図１２に示す状態に近い）から開かれた９０度（図１１に示す状態）の範囲で回動する。   The dust removal member 28 has a vertical dust removal body 42 and a horizontal dust removal body 43. The lower end of the vertical dust remover 42 and the rear end of the horizontal dust remover 43 are coupled to each other by a support shaft 44 so as to be rotatable. The vertical dust remover 42 and the horizontal dust remover 43 rotate within a range of 0 degrees (close to the state shown in FIG. 12) from the folded state to 90 degrees (state shown in FIG. 11).

縦置除塵体４２は、下端にストッパー５１を有する。除塵部材２８が９０度まで開いたところで、横置除塵体４３はストッパー５１で抑えられ、それ以上は開かない。   The vertical dust remover 42 has a stopper 51 at the lower end. When the dust removing member 28 is opened up to 90 degrees, the horizontal dust removing body 43 is held by the stopper 51 and cannot be opened any further.

なお、最大開き角度は、横置除塵体４３が集塵室３の内底部に接触しなければ、９０度以下でも９０度以上でもよい。   The maximum opening angle may be 90 degrees or less or 90 degrees or more as long as the horizontal dust remover 43 does not contact the inner bottom of the dust collection chamber 3.

縦置除塵体４２は、上側両端に支持軸突起４５が設けられる除塵枠体部４６を有する。掃除機本体ケース１は、図１８に示すように、集塵室３と後部室を仕切る中間仕切壁４７を有する。この中間仕切壁４７は、集塵室３側に縦に走る二つの支持リブ４８が間隔を隔てて設けられる。支持リブ４８は、図１９に示すように、上側に支持孔４９を有する。   The vertical dust removing body 42 has a dust removing frame body portion 46 provided with support shaft protrusions 45 at both upper ends. As shown in FIG. 18, the cleaner body case 1 includes an intermediate partition wall 47 that partitions the dust collection chamber 3 and the rear chamber. The intermediate partition wall 47 is provided with two support ribs 48 that run vertically on the dust collection chamber 3 side with an interval therebetween. As shown in FIG. 19, the support rib 48 has a support hole 49 on the upper side.

この支持孔４９に縦置除塵体４２の支持軸突起４５は回動自在に嵌まる。これにより、除塵部材２８は、集塵室３に揺振自在に置かれる。   The support shaft protrusion 45 of the vertical dust remover 42 is fitted into the support hole 49 so as to be rotatable. Thereby, the dust removal member 28 is placed in the dust collection chamber 3 so as to be freely swingable.

支持リブ４８は、図１９に示すように、対向面（内側面）に支持孔４９の上側から支持リブ４８に向けて形成された傾斜溝５０を有する。この傾斜溝５０は、上側に向かって外向きに傾く。支持軸突起４５も端側が傾斜面を有する。このため、支持軸突起４５を傾斜溝５０に沿って上から下に滑らせることにより、支持軸突起４５は支持孔４９に容易に嵌る。除塵部材２８の取り付けが容易に行なわれる。   As shown in FIG. 19, the support rib 48 has an inclined groove 50 formed on the opposing surface (inner surface) from the upper side of the support hole 49 toward the support rib 48. The inclined groove 50 is inclined outward toward the upper side. The support shaft protrusion 45 also has an inclined surface on the end side. For this reason, the support shaft protrusion 45 is easily fitted into the support hole 49 by sliding the support shaft protrusion 45 from the top to the bottom along the inclined groove 50. The dust removing member 28 can be easily attached.

除塵回転体３０は、図２２、図２３、図２４に示すように、外周に巻装される除塵バネ６０を有する。除塵バネ６０は、除塵回転体３０の長手方向に沿って螺旋状に巻かれ、多角形ないし外周に突き出る複数の突起を有する。除塵部材２８の縦置除塵体４２に備える付勢バネ６２は、縦置除塵体４２を後側に引く。   As shown in FIGS. 22, 23, and 24, the dust removal rotating body 30 has a dust removal spring 60 that is wound around the outer periphery. The dust removal spring 60 is spirally wound along the longitudinal direction of the dust removal rotary body 30, and has a plurality of protrusions protruding from a polygon or outer periphery. The biasing spring 62 provided in the vertical dust removing body 42 of the dust removing member 28 pulls the vertical dust removing body 42 rearward.

集塵袋２５は、図２４、図６に示すように、後側が除塵部材２８の縦置除塵体４２に、下側が横置除塵体４３に当接する。除塵回転体３０が図２４の（ａ）、（ｂ）、（ｃ）に示すように回転することにより、除塵部材２８は、付勢バネ６２に抗して左右に振動する。   As shown in FIGS. 24 and 6, the dust collection bag 25 is in contact with the vertical dust removing body 42 of the dust removing member 28 on the rear side and the horizontal dust removing body 43 on the lower side. When the dust removal rotating body 30 rotates as shown in FIGS. 24A, 24 </ b> B, and 24 </ b> C, the dust removal member 28 vibrates left and right against the biasing spring 62.

集塵袋２５の後側は、縦置除塵体４２により前後に揺すられ、下側は横置除塵体４３で前後に擦られるとともに上下に多少振られる。この振動により、集塵袋２５内に付着する塵埃が除塵され、集塵袋２５の通気性が回復し、更なる吸塵ができる。これを繰り返すことにより、集塵袋２５内が一杯になるまで吸塵できる。   The rear side of the dust bag 25 is shaken back and forth by the vertical dust remover 42, and the lower side is rubbed back and forth by the horizontal dust remover 43 and slightly shaken up and down. Due to this vibration, dust adhering to the dust bag 25 is removed, the air permeability of the dust bag 25 is restored, and further dust absorption can be performed. By repeating this, dust can be absorbed until the inside of the dust bag 25 becomes full.

集塵室内の掃除について説明する。   The cleaning of the dust collection chamber will be described.

塵埃は、集塵袋２５内に集塵される。しかし、集塵袋２５を取り外す際、集塵袋２５内に溜まった塵埃が誤って集塵室３の下部にこぼれる場合がある。この時、蓋体５を開いて、集塵室３から集塵袋２５を外し、内底部に溜まった細塵の掃除をする。   The dust is collected in the dust collection bag 25. However, when removing the dust bag 25, the dust accumulated in the dust bag 25 may accidentally spill into the lower part of the dust chamber 3. At this time, the lid 5 is opened, the dust collection bag 25 is removed from the dust collection chamber 3, and the fine dust accumulated in the inner bottom portion is cleaned.

この際に、除塵部材２８の横置除塵体４３を図１２に示すように折り畳むことにより、内底部側から横置除塵体４３が一時的に除かれた状態になる。このため、内底部の掃除が容易に、しかも細塵を残らず、掃除できる。   At this time, by folding the horizontal dust removing body 43 of the dust removing member 28 as shown in FIG. 12, the horizontal dust removing body 43 is temporarily removed from the inner bottom side. For this reason, it is possible to clean the inner bottom easily and without leaving fine dust.

横置除塵体４３は、図７〜図１０に示すように、前後方向に延在する複数のスリット６３が並ぶように設けられている。集塵袋２５を抜けた気流は、スリット６３を通って電動送風機２６へと流れる。横置除塵体４３のスリット６３は、気流の流れを良くするのである。   As shown in FIGS. 7 to 10, the horizontal dust removing body 43 is provided so that a plurality of slits 63 extending in the front-rear direction are arranged. The airflow that has passed through the dust collection bag 25 flows to the electric blower 26 through the slit 63. The slit 63 of the horizontal dust removing body 43 improves the flow of airflow.

スリット６３には、集塵室３の内底部に一体に設けられた案内リブ６４が摺動自在に嵌る。この案内リブ６４は、除塵動作の前後方向振動ではガイドとして機能する。前後方向振動と交差する方向の動きは案内リブ６４により規制される。   Into the slit 63, a guide rib 64 provided integrally with the inner bottom portion of the dust collecting chamber 3 is slidably fitted. The guide rib 64 functions as a guide in the longitudinal vibration of the dust removal operation. The movement in the direction crossing the longitudinal vibration is restricted by the guide rib 64.

このため、電気掃除機本体の置かれる姿勢が横倒しになっていても案内リブ６４の案内により、除塵部材２８の除塵動作は作動不良を起こすことなく、円滑に行なわれる。   For this reason, even if the electric vacuum cleaner main body is placed on its side, the dust removing operation of the dust removing member 28 is smoothly performed without causing malfunction due to the guidance of the guide rib 64.

また、除塵部材２８は横置除塵体４３をストッパー５１で支えているので、除塵動作で横置除塵体４３と集塵室３の内底部は擦れ合うことなく、円滑な除塵動作が行なわれる。   Further, since the dust removing member 28 supports the horizontal dust remover 43 with the stopper 51, the dust removal operation is performed smoothly without rubbing between the horizontal dust remover 43 and the inner bottom portion of the dust collecting chamber 3.

図１１、図１２、図１５、図２１に示すように、除塵駆動伝達ユニット２９の除塵回転体３０は、縦置除塵体４２の下端に当接する。この当接部は、縦置除塵体４２の下端後部で支軸４４の近傍に位置し、円弧形状を有する。この円弧面は、縦置除塵体４２の幅範囲に亘り形成されている。   As shown in FIGS. 11, 12, 15, and 21, the dust removal rotating body 30 of the dust removal drive transmission unit 29 contacts the lower end of the vertical dust removal body 42. This abutting portion is located in the vicinity of the support shaft 44 at the lower end rear portion of the vertical dust removing body 42 and has an arc shape. This circular arc surface is formed over the width range of the vertical dust removing body 42.

この円弧面の当接部に除塵回転体３０の除塵バネ６０が当接する。除塵バネ６０の多角形ないし外周に突き出る複数の突起が当接しても、円弧面により除塵回転体３０の円滑な回転が維持される。これにより、除塵部材２８の振動作動が良好に行なわれ、集塵袋２５の除塵が良く行なわれる。   The dust removal spring 60 of the dust removal rotary body 30 abuts on the abutting portion of the arc surface. Even if a plurality of protrusions protruding from the polygon or outer periphery of the dust removal spring 60 come into contact with each other, smooth rotation of the dust removal rotating body 30 is maintained by the arc surface. Thereby, the vibration operation of the dust removing member 28 is satisfactorily performed, and the dust collecting bag 25 is well dedusted.

図７、図９、図１０に示すように、除塵部材２８の横置除塵体４３は、前後に通じる方向から見て中央が隆起する形状を有する。このような形状に有するので、平板状のものに比べ、構造上の強度が高まる。   As shown in FIGS. 7, 9, and 10, the horizontal dust removal body 43 of the dust removal member 28 has a shape in which the center rises when viewed from the front-rear direction. Since it has such a shape, the structural strength is higher than that of a flat plate.

横置除塵体４３は、縦置除塵体４２の下端後部に支軸４４で片持ち支持され、かつスリット６３が形成された薄手のものである。中央が隆起する強い構造であるので、折れ曲がることなく、集塵袋２５を下から支えることができる。このため、横置除塵体４３が集塵室３の内底部に接触することも生じることもなく、除塵の振動動作が良好に行なわれる。   The horizontal dust remover 43 is a thin one that is cantilevered by a support shaft 44 at the lower end rear portion of the vertical dust remover 42 and has a slit 63 formed therein. Since the center is a strong structure, the dust bag 25 can be supported from below without being bent. For this reason, the horizontal dust removing body 43 does not come into contact with the inner bottom portion of the dust collecting chamber 3, and the dust removing vibration operation is performed well.

図１８に示すように、集塵室３と後部室を仕切る中間仕切壁４７は、内部流通口６５を有する。内部流通口６５は、電動送風機２６の送風部（ファン）の吸込口に対向するように中央から片側に偏在させて設ける。   As shown in FIG. 18, the intermediate partition wall 47 that partitions the dust collection chamber 3 and the rear chamber has an internal circulation port 65. The internal circulation port 65 is provided so as to be unevenly distributed from the center to one side so as to face the suction port of the blower (fan) of the electric blower 26.

集塵室３に流入する気流は、内部流通口６５を通って電動送風機２６に流れる。内部流通口６５には、複数の縦格子リブ６６が設けられる。この縦格子リブ６６は、大き目の異物が電動送風機２６に強い込まれるのを阻止する。   The airflow flowing into the dust collection chamber 3 flows through the internal circulation port 65 to the electric blower 26. The internal circulation port 65 is provided with a plurality of vertical lattice ribs 66. The vertical lattice rib 66 prevents a large foreign object from being forced into the electric blower 26.

図７、図８に示すように、集塵室３に内置されると除塵部材２８は、縦置除塵体４２が内部流通口６５のところに対向するように置かれる。縦置除塵体４２の巾は、集塵室３の横巾（中間仕切壁４７の横幅）より狭い。このため、コードリール２７側に対応する中間仕切壁４７のところには、縦置除塵体４２は存在しない。   As shown in FIGS. 7 and 8, when placed in the dust collection chamber 3, the dust removing member 28 is placed so that the vertical dust removing body 42 faces the internal circulation port 65. The width of the vertical dust removing body 42 is narrower than the width of the dust collection chamber 3 (the width of the intermediate partition wall 47). For this reason, the vertical dust removing body 42 does not exist at the intermediate partition wall 47 corresponding to the cord reel 27 side.

横置除塵体４３は、縦置除塵体４２の横巾より広い横巾を有し、集塵室３の内底部の横幅範囲に広がる。   The horizontal dust removing body 43 has a wider width than that of the vertical dust removing body 42 and extends in the width range of the inner bottom portion of the dust collecting chamber 3.

集塵袋２５内に吸い込まれた塵埃は、集塵袋２５の後部側で内部流通口６５に近いところの内側に多く付着する。この多く付着するところを積極的に除塵振動させるために縦置除塵体４２の横巾を集塵室３の横巾よりも狭くした。   A large amount of dust sucked into the dust bag 25 adheres to the inner side of the dust bag 25 near the internal circulation port 65 on the rear side. The horizontal width of the vertical dust removing body 42 is made narrower than the horizontal width of the dust collecting chamber 3 in order to positively vibrate and remove dust at the place where many adhere.

集塵袋２５の底側は、塵埃付着の偏りは少ないので、除塵振動が出来るだけ広い範囲に及ぶように横置除塵体４３の横巾を縦置除塵体４２よりも広くした。   Since the bottom of the dust collection bag 25 is less biased to adhere to dust, the horizontal width of the horizontal dust remover 43 is made wider than that of the vertical dust remover 42 so that dust removal vibrations are as wide as possible.

なお、縦置除塵体４２と横置除塵体４３の横幅を同じにすることも可能である。   The horizontal width of the vertical dust remover 42 and the horizontal dust remover 43 can be the same.

図１７、図１０、図１５を引用して付勢バネの取り付けについて説明する。   The attachment of the urging spring will be described with reference to FIGS. 17, 10, and 15.

縦置除塵体４２の除塵枠体部４６は、一方の側面上部にバネ収容部６７を有する。   The dust-removing frame body portion 46 of the vertical dust-removing body 42 has a spring accommodating portion 67 on one side surface upper portion.

バネ収容部６７は、除塵枠体部４６の外側面と、前側壁６８と、外側壁６９で形成される。バネ収容部６７の上側と後側は壁部がなく、開放になっている。前述した一方の支持軸突起４５は、外側壁６９の外側に設けられているのである。   The spring accommodating portion 67 is formed by the outer side surface of the dust removing frame body portion 46, the front side wall 68, and the outer side wall 69. The upper side and the rear side of the spring accommodating portion 67 have no wall portion and are open. The one support shaft protrusion 45 described above is provided outside the outer wall 69.

バネ収容部６７内には、除塵枠体部４６の外側面に付勢バネ６２の中心を支持するバネ支持軸突起７０と、付勢バネ６２の一端７１を係止する係止突起７２と、付勢バネ６２の他端７３を係止する仮止部７４を有する。   In the spring accommodating portion 67, a spring support shaft projection 70 that supports the center of the biasing spring 62 on the outer surface of the dust removing frame body portion 46, a locking projection 72 that locks one end 71 of the biasing spring 62, A temporary fixing portion 74 for locking the other end 73 of the urging spring 62 is provided.

付勢バネ６２は、図１７に示すように、バネ収容部６７内に収納され、かつ他端７３の押圧部７５が中間仕切壁４７に押圧する。これにより、縦置除塵体４２は付勢バネ６２の力で、支持軸突起４５を支点としてＰ矢印方向の回転力が付与される。   As shown in FIG. 17, the urging spring 62 is accommodated in the spring accommodating portion 67, and the pressing portion 75 at the other end 73 is pressed against the intermediate partition wall 47. Thereby, the vertical dust removing body 42 is given a rotational force in the direction of arrow P with the support shaft projection 45 as a fulcrum by the force of the biasing spring 62.

前述したように、付勢バネ６２は、除塵回転体３０の回転で縦置除塵体４２を押す力に抗するように作用する。除塵回転体３０の回転による押力と付勢バネ６２の抗する力により、除塵部材２８は除塵振動動作をする。   As described above, the urging spring 62 acts against the force pushing the vertical dust removal body 42 by the rotation of the dust removal rotary body 30. The dust removing member 28 performs a dust removing vibration operation by the pressing force generated by the rotation of the dust removing rotating body 30 and the force resisted by the biasing spring 62.

付勢バネ６２は、バネ収容部６７内に挿入し、付勢バネ６２の中心をバネ支持軸突起７０に嵌め、一端７１を係止突起７２に、他端７３を仮止部７４に係止することで、簡単に組み込まれる。また、除塵枠体部４６は支持軸突起４５を支持リブ４８の支持孔４９に嵌め込むことにより、押圧部７５が中間仕切壁４７に押圧して付勢バネ６２として機能するようになるので、除塵枠体部４６の取り付けも容易である。   The urging spring 62 is inserted into the spring accommodating portion 67, the center of the urging spring 62 is fitted to the spring support shaft projection 70, one end 71 is locked to the locking projection 72, and the other end 73 is locked to the temporary locking portion 74. By doing so, it is easily integrated. Further, since the dust removing frame body portion 46 fits the support shaft protrusion 45 into the support hole 49 of the support rib 48, the pressing portion 75 presses against the intermediate partition wall 47 and functions as the biasing spring 62. Attachment of the dust removing frame 46 is also easy.

バネ支持軸突起７０は、支持軸突起４５（除塵枠体部４６を回動自在に支持する支持点）の近傍に位置しているが、同心上にすることも可能である。   The spring support shaft protrusion 70 is located in the vicinity of the support shaft protrusion 45 (a support point for rotatably supporting the dust removing frame body portion 46), but may be concentric.

図１０、図１５等に示されるように、バネ収容部６７の下側には、除塵枠体部４６の側面に亘り、補強部７６が設けられる。この補強部７６により、除塵枠体部４６とバネ収容部６７との一体構造が補強される。補強部７６が梯子状に多数の孔を有するのは、通気性をより高めるためである。   As shown in FIGS. 10, 15, and the like, a reinforcing portion 76 is provided below the spring accommodating portion 67 over the side surface of the dust removing frame body portion 46. With this reinforcing portion 76, the integral structure of the dust removal frame body portion 46 and the spring accommodating portion 67 is reinforced. The reason why the reinforcing portion 76 has a large number of holes in a ladder shape is to improve air permeability.

図１６、図２０に示すように、保護フィルタ部７７は、フィルタ支持枠７８と、支骨７９を縦横に設けた格子と、保持つめ８０と、保護通気フィルタ９０を有する。   As shown in FIGS. 16 and 20, the protective filter portion 77 includes a filter support frame 78, a lattice provided with support frames 79 in the vertical and horizontal directions, a holding claw 80, and a protective ventilation filter 90.

フィルタ支持枠７８と別体の保護通気フィルタ９０は、支骨７９と、保持つめ８０とによりフィルタ支持枠７８に保持される。   The protective ventilation filter 90, which is separate from the filter support frame 78, is held on the filter support frame 78 by a support frame 79 and a holding claw 80.

保護通気フィルタ９０は、通気目が集塵袋２５より粗く、フィルタ支持枠７８の格子目よりも細やかで、可撓性を有する。フィルタ支持枠７８の格子に添え当てた保護通気フィルタ９０は、周縁を保持つめ８０のところに差し込む。こうして、保護通気フィルタ９０は、フィルタ支持枠７８に保持される。   The protective ventilation filter 90 has a ventilation opening that is coarser than the dust collection bag 25, is finer than the lattice of the filter support frame 78, and has flexibility. The protective ventilation filter 90 attached to the grid of the filter support frame 78 is inserted into the holding pawl 80 at the periphery. Thus, the protective ventilation filter 90 is held by the filter support frame 78.

図９は、除塵部材２８の除塵枠体部４６に保護フィルタ部７７が取り付けられたところを示す。図１０は、保護フィルタ部７７が除塵枠体部４６から外されたところを示す。   FIG. 9 shows that the protective filter portion 77 is attached to the dust removing frame body portion 46 of the dust removing member 28. FIG. 10 shows that the protective filter part 77 is removed from the dust removing frame part 46.

除塵枠体部４６は、図２０に示すように、上下に走る差込溝９１を有する。この差込溝９１に保護フィルタ部７７のフィルタ支持枠７８が摺動自在に嵌め込まれる。図１４は、保護フィルタ部７７を除塵枠体部４６に嵌め込み始めたところを示す。図１３は、保護フィルタ部７７を除塵枠体部４６に嵌め込み終えたところを示している。   As shown in FIG. 20, the dust removing frame body portion 46 has insertion grooves 91 that run up and down. The filter support frame 78 of the protective filter portion 77 is slidably fitted into the insertion groove 91. FIG. 14 shows a state where the protective filter portion 77 has started to be fitted into the dust removing frame body portion 46. FIG. 13 shows a state where the protective filter portion 77 has been fitted into the dust removal frame body portion 46.

保護フィルタ部７７が取り付け、取り外しができるので、除塵部材２８のメンテナンスに際しては、保護フィルタ部７７を外しておいて除塵枠体部４６だけで脱着をする。保護フィルタ部７７が着いていない合成樹脂性の除塵枠体部４６は撓みやすく、除塵枠体部４６の着脱が容易である。   Since the protective filter portion 77 can be attached and detached, when the dust removing member 28 is maintained, the protective filter portion 77 is removed and the dust removing frame body portion 46 is attached and detached. The synthetic resin type dust removing frame body 46 to which the protective filter 77 is not attached is easy to bend, and the dust removing frame part 46 can be easily attached and detached.

この保護フィルタ部７７は、内部流通口６５上流側に位置する。集塵袋２５が破れても、保護フィルタ部７７により、塵埃が内部流通口６５を通って電動送風機２６に吸い込まれるのを防止できる。   This protective filter part 77 is located upstream of the internal circulation port 65. Even if the dust collection bag 25 is torn, the protective filter portion 77 can prevent the dust from being sucked into the electric blower 26 through the internal circulation port 65.

保護フィルタ部７７は、空気流の下流側面の周縁が保持つめ８０で保持され、それに加え、下流側面側が前述した縦格子リブ６６で抑えられるので、保護フィルタ部７７が除塵枠体部４６から脱落する不具合は生じない。   In the protective filter 77, the peripheral edge of the downstream side of the air flow is held by the holding pawl 80, and in addition to that, the downstream side is suppressed by the above-described vertical lattice rib 66, so the protective filter 77 is dropped from the dust removing frame body 46. There is no problem to do.

保護フィルタ部７７は、図１６に示すように、フィルタ支持枠７８の上部の側端に突き出す取っ手９２を有する。保護フィルタ部７７の取り付け、取り外しでは、取っ手９２を掴んで行なう。   As shown in FIG. 16, the protective filter portion 77 has a handle 92 that protrudes from the upper side end of the filter support frame 78. The attachment / detachment of the protective filter 77 is performed by grasping the handle 92.

取っ手９２は、保護フィルタ部７７に除塵枠体部４６を取り付けると、図８、図９、図１３、図１５に示すように、バネ収容部６７の上側を塞ぐ蓋として機能する。取っ手９２で、バネ収容部６７に大きめ目の異物が入るのを防ぐことができる。   When the dust removing frame body portion 46 is attached to the protective filter portion 77, the handle 92 functions as a lid that closes the upper side of the spring accommodating portion 67 as shown in FIGS. 8, 9, 13, and 15. The handle 92 can prevent a large foreign matter from entering the spring accommodating portion 67.

集塵室３の内底部は、図６、図７に示すように、隆起している。掃除機本体ケース１の前側下面にキャスター９３を取り付ける窪みを設けるために隆起させた。この隆起に合うように横置除塵体４３の中央を隆起させた。   As shown in FIGS. 6 and 7, the inner bottom portion of the dust collection chamber 3 is raised. The vacuum cleaner body case 1 was raised to provide a recess for attaching the caster 93 to the front lower surface. The center of the horizontal dust removing body 43 was raised so as to match this uplift.

これにより、横置除塵体４３と横置除塵体４３との間にできる無駄な空間は少なく、集塵室３内で集塵袋２５がより大きく膨らみ、集塵量の増加を図ることができる。   Thereby, there is little useless space between the horizontal dust removal body 43 and the horizontal dust removal body 43, and the dust collection bag 25 can be further expanded in the dust collection chamber 3, thereby increasing the amount of dust collection. .

次に除塵駆動伝達ユニットの関連について説明する。   Next, the relationship of the dust removal drive transmission unit will be described.

除塵駆動伝達ユニット２９は、図２３、図２８、図２９、図３３に示すように、支持フレーム９４を有する。   As shown in FIGS. 23, 28, 29, and 33, the dust removal drive transmission unit 29 has a support frame 94.

支持フレーム９４は、矩形の枠体部９５と、枠体部９５の片側を塞ぐ底板部９６と、枠体部９５の短辺側に底板部９６の反対側に向かって立つ二つの回転体支持板９７を有する。   The support frame 94 includes a rectangular frame body 95, a bottom plate portion 96 that covers one side of the frame body portion 95, and two rotating body supports that stand on the short side of the frame body portion 95 toward the opposite side of the bottom plate portion 96. A plate 97 is provided.

二つの回転体支持板９７の周端縁と、枠体部９５の長辺側端縁には、気密シール９８が設けられる。この気密シール９８は、図３４に示すように、連なった環に形成されている。連なった環の気密シール９８は、つなぎ合わせの隙間がないので、シール性が高まる。   An airtight seal 98 is provided at the peripheral edge of the two rotating body support plates 97 and the long side edge of the frame body portion 95. As shown in FIG. 34, the airtight seal 98 is formed in a continuous ring. Since the hermetic seal 98 of the continuous ring has no gap for joining, the sealing performance is improved.

気密シール９８は、枠体部９５と一体に合成樹脂で成型される。気密シール９８は、シール機能を有するように枠体部９５よりも軟質な合成樹脂で成型される。成型用の金型で成型された枠体部９５を別の金型に移し、軟質の合成樹脂を注入することにより、枠体部９５と気密シール９８は一体に成型される。   The hermetic seal 98 is molded of synthetic resin integrally with the frame body portion 95. The hermetic seal 98 is molded from a synthetic resin that is softer than the frame body portion 95 so as to have a sealing function. The frame body part 95 and the airtight seal 98 are integrally molded by transferring the frame body part 95 molded with a molding die to another mold and injecting a soft synthetic resin.

気密シール９８は、枠体部９５と分離して、ばらばらになることが生じないので、組立の際の取り扱い性が向上する。また、気密シール９８は軟質の合成樹脂で形成されるので、シール性が向上する。   Since the hermetic seal 98 is separated from the frame body portion 95 and does not break apart, the handleability during assembly is improved. Moreover, since the hermetic seal 98 is formed of a soft synthetic resin, the sealing performance is improved.

除塵駆動伝達ユニット２９の除塵回転体３０は、二つの回転体支持板９７に回転自在に支持される。除塵回転体３０は、図２９に示すように、両端側に支軸９９Ａ、９９Ｂを有する。   The dust removal rotary body 30 of the dust removal drive transmission unit 29 is rotatably supported by the two rotary body support plates 97. As shown in FIG. 29, the dust removal rotary body 30 has support shafts 99A and 99B on both ends.

伝達歯車４０は、除塵回転体３０の一方の端部側に設けられる。伝達歯車４０の軸部１１０を除塵回転体３０の一方の端部側にネジ等で締結して固定する。伝達歯車４０は除塵回転体３０の端部から離間したところに位置する。   The transmission gear 40 is provided on one end side of the dust removal rotary body 30. The shaft portion 110 of the transmission gear 40 is fastened and fixed to one end side of the dust removing rotator 30 with a screw or the like. The transmission gear 40 is positioned away from the end of the dust removal rotary body 30.

除塵回転体３０内には、一方向の回転が伝達され、他方向の回転が伝達されない、いわゆる一方向回転伝達クラッチ１０５が備わる。コードリール２７の駆動歯車４１、および伝達歯車４０を介してコードリール２７の回転は、除塵回転体３０に伝達される。   In the dust removal rotating body 30, a so-called one-way rotation transmission clutch 105 is provided, in which rotation in one direction is transmitted and rotation in the other direction is not transmitted. The rotation of the cord reel 27 is transmitted to the dust removal rotary body 30 via the drive gear 41 of the cord reel 27 and the transmission gear 40.

コードを引き出すときには除塵回転体３０は回されるが、コードを巻き取るときには除塵回転体３０は回されない。こうすることにより、コードリール２７の巻き取りバネを小型化でき、しかもコードの引き出しが軽くなる。   The dust removal rotator 30 is rotated when the cord is pulled out, but the dust removal rotator 30 is not rotated when the cord is wound. By doing so, the winding spring of the cord reel 27 can be reduced in size, and the cord can be pulled out lightly.

支持フレーム９４の二つの回転体支持板９７は、除塵回転体３０の支軸９９Ａ，９９Ｂを回転自在に支持する軸受１１１Ａ、１１１Ｂを有する。伝達歯車４０が設けられる支軸９９Ｂを回転自在に支持する方の軸受１１１Ｂは、貫通するように形成される。   The two rotary body support plates 97 of the support frame 94 include bearings 111A and 111B that rotatably support the support shafts 99A and 99B of the dust removal rotary body 30. The bearing 111B that rotatably supports the support shaft 99B on which the transmission gear 40 is provided is formed so as to penetrate therethrough.

伝達歯車４０が設けられない方の支軸９９Ａを支持する軸受１１１Ａは、奥側が塞がるように形成される。軸受１１１Ａは、奥側が塞がっているので、軸受１１１Ａから回転体支持板９７の外側に空気は漏れない。   The bearing 111A that supports the support shaft 99A on which the transmission gear 40 is not provided is formed so that the back side is closed. Since the inner side of the bearing 111A is closed, air does not leak from the bearing 111A to the outside of the rotating body support plate 97.

しかし、軸受１１１Ｂは貫通しているので、回転体支持板９７の外側に空気は漏れる。そこで、回転体支持板９７の外面側に、軸受１１１Ｂと支軸９９Ｂの隙間を封じる軸シール１１２を設けた。この軸シール１１２により、軸受１１１Ｂを通じて回転体支持板９７の外側に漏れる空気漏洩は阻止される。   However, since the bearing 111B penetrates, the air leaks to the outside of the rotating body support plate 97. Therefore, a shaft seal 112 is provided on the outer surface side of the rotating body support plate 97 to seal the gap between the bearing 111B and the support shaft 99B. The shaft seal 112 prevents air leakage from leaking to the outside of the rotating body support plate 97 through the bearing 111B.

図２１、図２３に示すように、掃除機本体ケース１は底面に除塵駆動伝達ユニット２９が装着される装着開口部１１３を有する。この装着開口部１１３には、除塵駆動伝達ユニット２９が外側から着脱自在に装着される。   As shown in FIGS. 21 and 23, the cleaner body case 1 has a mounting opening 113 to which the dust removal drive transmission unit 29 is mounted on the bottom surface. A dust removal drive transmission unit 29 is detachably attached to the attachment opening 113 from the outside.

このように、支持フレーム９４に除塵回転体３０、伝達歯車４０をまとめてユニット化し、ユニットになった除塵駆動伝達ユニット２９を掃除機本体ケース１の装着開口部１１３に取り付けるので、組み立てが容易に行なわれる。   Thus, the dust removal rotating body 30 and the transmission gear 40 are integrated into a unit on the support frame 94, and the dust removal drive transmission unit 29 as a unit is attached to the mounting opening 113 of the cleaner body case 1, so that assembly is easy. Done.

装着開口部１１３は、除塵回転体３０や支持フレーム９４が置かれるところには窪み部１１４が形成され、伝達歯車４０が置かれるところには後部室（コードリール２７、電動送風機２６が置かれる）側に臨む開口が形成されている。   The mounting opening 113 is formed with a recess 114 where the dust removing rotary body 30 and the support frame 94 are placed, and a rear chamber (where the code reel 27 and the electric blower 26 are placed) where the transmission gear 40 is placed. An opening facing the side is formed.

窪み部１１４は、図２３、図２７、図３２に示すように、奥側に除塵用開口１１５を有する。この除塵用開口１１５は、集塵室３内に置かれる縦置除塵体４２の下端側に臨んでいる。   As shown in FIGS. 23, 27, and 32, the recess 114 has a dust removal opening 115 on the back side. The dust removal opening 115 faces the lower end side of the vertical dust removal body 42 placed in the dust collection chamber 3.

また、窪み部１１４は、伝達歯車４０が位置する方の側面側に伝達開口１１６を有する。この伝達開口１１６を介して窪み部１１４は、後部室側と連通している。   In addition, the recess 114 has a transmission opening 116 on the side surface where the transmission gear 40 is located. The recess 114 communicates with the rear chamber side through the transmission opening 116.

装着開口部１１３に装着された除塵駆動伝達ユニット２９の除塵回転体３０は、外周側の除塵バネ６０が除塵用開口１１５から集塵室３に突き出し、縦置除塵体４２の下端側（円弧面の当接部）に当接する。   In the dust removal rotary body 30 of the dust removal drive transmission unit 29 attached to the attachment opening 113, the dust removal spring 60 on the outer peripheral side protrudes from the dust removal opening 115 to the dust collection chamber 3, and the lower end side (arc surface) of the vertical dust removal body 42. Abutting part).

伝達歯車４０は、コードリール２７の駆動歯車４１に噛み合わされる。伝達歯車４０の軸部１１０は、伝達開口１１６に置かれる。   The transmission gear 40 is meshed with the drive gear 41 of the cord reel 27. The shaft portion 110 of the transmission gear 40 is placed in the transmission opening 116.

窪み部１１４は、図２３、図２５〜図２７、図３３、図３４に示すように、窪み部１１４の底に近い低位置段部１１７と、底から離れた高位置段部１１８とを有する。また、窪み部１１４は、長手方向の端側に接合突起１１９，１２０を有する。   As shown in FIGS. 23, 25 to 27, 33, and 34, the recess 114 has a low position step 117 near the bottom of the recess 114 and a high position step 118 away from the bottom. . Moreover, the hollow part 114 has joining protrusions 119 and 120 on the end side in the longitudinal direction.

窪み部１１４の低位置段部１１７には、気密シール９８の辺９８Ｂが当接する。窪み部１１４の高位置段部１１８には、気密シール９８の辺９８Ａが当接する。接合突起１１９には、気密シール９８の辺９８Ｃが当接する。接合突起１２０には、気密シール９８の辺９８Ｄが当接する。   The side 98 </ b> B of the hermetic seal 98 abuts on the low position stepped portion 117 of the recess 114. The side 98 </ b> A of the hermetic seal 98 abuts on the high position step portion 118 of the depression 114. A side 98 </ b> C of the hermetic seal 98 abuts on the joint protrusion 119. The side 98D of the hermetic seal 98 abuts on the joint protrusion 120.

これらの当接による気密シール９８のシールにより、除塵用開口１１５を通じ、集塵室３と掃除機本体ケース１の外側間で空気が流通するのは断たれる。このため、装着開口部１１３を通じて集塵室３と掃除機本体ケース１の外側間で空気が流れる空気漏れは生じない。   By the sealing of the airtight seal 98 by the contact, air is prevented from flowing between the dust collecting chamber 3 and the outside of the cleaner body case 1 through the dust removal opening 115. For this reason, there is no air leakage through which air flows between the dust collection chamber 3 and the outside of the cleaner body case 1 through the mounting opening 113.

また、気密シール９８は、窪み部１１４が伝達開口１１６を介して後部室（コードリール２７、電動送風機２６が置かれる）に連通するところのシールを併せてしている。このため、集塵室３と後部室の間も空気の流通は断たれ、空気漏れは生じない。   The hermetic seal 98 also serves as a seal where the recess 114 communicates with the rear chamber (where the code reel 27 and the electric blower 26 are placed) via the transmission opening 116. For this reason, air circulation is also cut off between the dust collection chamber 3 and the rear chamber, and no air leakage occurs.

図３１、図３２は、電気掃除機本体の装着開口部１１３に装着されている除塵駆動伝達ユニットを横方向に断面したところを示している。   31 and 32 show a cross section of the dust removal drive transmission unit mounted in the mounting opening 113 of the vacuum cleaner body in the lateral direction.

図３２は、除塵駆動伝達ユニット２９から除塵回転体３０を外したところを示している。窪み部１１４の底に除塵用開口１１５が見える。また、接合突起１１９、１２０は、図示されていないが、二つの回転体支持板９７のところに位置する。   FIG. 32 shows the dust removal rotating body 30 removed from the dust removal drive transmission unit 29. A dust removal opening 115 is visible at the bottom of the recess 114. Further, although not shown, the joint protrusions 119 and 120 are located at the two rotating body support plates 97.

窪み部１１４に内側面に突出するように設けられた接合突起１１９、１２０は、幅が気密シール９８の幅よりも狭い。接合突起１１９、１２０に押圧された気密シール９８を押し付けることにより、接合突起１１９、１２０が気密シール９８に食い込み気密が向上する。   The joint protrusions 119 and 120 provided so as to protrude from the inner surface of the recess 114 have a width smaller than that of the hermetic seal 98. By pressing the airtight seal 98 pressed against the joint protrusions 119 and 120, the joint protrusions 119 and 120 bite into the airtight seal 98 and the airtightness is improved.

除塵駆動伝達ユニット２９は、掃除機本体ケース１に設けたねじボス１３０、１３１にねじ込むネジ１３２により締め付け固定される。除塵駆動伝達ユニット２９に設けたネジ通穴１３３、１３４は、二つの回転体支持板９７の外側に設けた。   The dust removal drive transmission unit 29 is fastened and fixed by screws 132 screwed into screw bosses 130 and 131 provided in the cleaner body case 1. Screw through holes 133 and 134 provided in the dust removal drive transmission unit 29 are provided outside the two rotating body support plates 97.

二つの回転体支持板９７の内側にネジ通穴を設けると、ネジ通穴にも気密を施さなければならない。ネジ通穴を二つの回転体支持板９７の外側に設けることにより、気密を施す必要がなく、構成が簡単になる。   If screw through holes are provided inside the two rotating body support plates 97, the screw through holes must be airtight. By providing the screw through holes on the outer sides of the two rotating body support plates 97, it is not necessary to provide airtightness, and the configuration is simplified.

次に吸塵時の通気確保について述べる。   Next, securing airflow during dust absorption will be described.

図６、図２２、図３５〜図３７に沿って説明する。   This will be described with reference to FIGS. 6, 22, and 35 to 37.

集塵袋２５は、集塵室３に内置される。集塵袋２５は、厚紙等の硬質材料からなる口板１３５と、この口板１３５に接着された通気性の袋部１３６とを有する。袋部１３６は紙等で作られる。   The dust collection bag 25 is placed in the dust collection chamber 3. The dust collection bag 25 has a mouth plate 135 made of a hard material such as cardboard, and a breathable bag portion 136 bonded to the mouth plate 135. The bag part 136 is made of paper or the like.

口板クランプ１３７は、集塵室３のホース差込口４側に設けられる。集塵室３に装着され、口板１３５が口板クランプ１３７に保持された集塵袋２５は、口板１３５の塵埃吸気口１３８がホース差込口４に向き合うように置かれる。   The mouth plate clamp 137 is provided on the hose insertion port 4 side of the dust collection chamber 3. The dust collection bag 25 attached to the dust collection chamber 3 and having the mouth plate 135 held by the mouth plate clamp 137 is placed so that the dust inlet 138 of the mouth plate 135 faces the hose insertion port 4.

蓋体５は、集塵室３の一部を構成する。この蓋体５の内側に通風部材１４０が設けられる。   The lid 5 constitutes a part of the dust collection chamber 3. A ventilation member 140 is provided inside the lid 5.

通風部材１４０は、中央にフィルタ収納部１４１と、フィルタ収納部１４１の外側に設けた流路空間１４２と、フィルタ収納部１４１と流路空間１４２を仕切る仕切壁１４３と、フィルタ収納部１４１の流入口１４４に設けた格子１４５と、通風部材１４０の両端に仕切壁１４３と対向するように設けた外側壁１４６を有する。   The ventilation member 140 includes a filter housing part 141 at the center, a flow path space 142 provided outside the filter storage part 141, a partition wall 143 that partitions the filter storage part 141 and the flow path space 142, and a flow of the filter storage part 141. A grid 145 provided at the inlet 144 and an outer wall 146 provided at both ends of the ventilation member 140 so as to face the partition wall 143 are provided.

流路空間１４２は、仕切壁１４３と外側壁１４６の間に形成される。通風部材１４０の入口１４７に向いている仕切壁１４３の前側は円弧形状を有する。   The flow path space 142 is formed between the partition wall 143 and the outer wall 146. The front side of the partition wall 143 facing the inlet 147 of the ventilation member 140 has an arc shape.

フィルタ収納部１４１には、濾過フィルタ１４８が収納される。フィルタ収納部１４１は、流路空間１４２の出口１４９と横並びの流出口１５０を有する。流出口１４９には、濾過フィルタ１４８を抑える支持部材１６０を設ける。   A filter filter 148 is stored in the filter storage unit 141. The filter storage unit 141 has an outlet 150 that is aligned with the outlet 149 of the flow path space 142. A support member 160 that suppresses the filtration filter 148 is provided at the outflow port 149.

通風部材１４０は、流入口１４４が集塵室３の内側を向くように蓋体５に取り付ける。また、通風部材１４０の入口１４７が集塵室３の前側に、流路空間１４２の出口１４９が集塵室３の後側に向くように通風部材１４０は配置される。   The ventilation member 140 is attached to the lid 5 such that the inlet 144 faces the inside of the dust collection chamber 3. The ventilation member 140 is arranged so that the inlet 147 of the ventilation member 140 faces the front side of the dust collection chamber 3 and the outlet 149 of the flow path space 142 faces the rear side of the dust collection chamber 3.

吸塵される塵埃は、ホース差込口４に挿入接続された吸い込みホース１３９（図２２）を流れて塵埃吸気口１３８から袋部１３６に入る。集塵室３内で膨れた袋部１３６の外周は、集塵室３の内面や通風部材１４０に張り付くが、通風部材１４０により通気が確保される。   Dust to be sucked flows through the suction hose 139 (FIG. 22) inserted and connected to the hose insertion port 4 and enters the bag portion 136 from the dust suction port 138. The outer periphery of the bag portion 136 swelled in the dust collection chamber 3 sticks to the inner surface of the dust collection chamber 3 and the ventilation member 140, but ventilation is ensured by the ventilation member 140.

すなわち、袋部１３６の外周が集塵室３に密着しているところでは、空気の流通が行なわれない。通気部材１４０に受け止められているところは、袋部１３６の外に抜けた空気は流入口１４４、濾過フィルタ１４８、流出口１５０へと流れる。また、入口１４７、流路空間１４２、出口１４９へと流れる空気の流れもある。このような空気の流通が通風部材１４０により確保されるのである。   That is, air circulation is not performed where the outer periphery of the bag portion 136 is in close contact with the dust collection chamber 3. Where the ventilation member 140 receives the air, the air that has flowed out of the bag portion 136 flows to the inlet 144, the filtration filter 148, and the outlet 150. There is also a flow of air that flows to the inlet 147, the channel space 142, and the outlet 149. Such air circulation is ensured by the ventilation member 140.

流出口１５０、出口１４９から吐出した空気は、図３５の矢印に示すように、下方に向かって流れ、内部流通口６５を経て電動送風機２６に吸い込まれる。   The air discharged from the outlet 150 and the outlet 149 flows downward and is sucked into the electric blower 26 through the internal circulation port 65 as shown by arrows in FIG.

斯かる流出口１５０、出口１４９から内部流通口６５に至る空気流路は狭い。狭い空気流路での流通が阻害されないように、除塵駆動伝達ユニット２９の除塵回転体３０を掃除機本体ケース１の内底側に配置したのである。   The air flow path from the outlet 150 and outlet 149 to the internal circulation port 65 is narrow. The dust removal rotary body 30 of the dust removal drive transmission unit 29 is arranged on the inner bottom side of the cleaner body case 1 so that the flow in the narrow air flow path is not hindered.

このように除塵回転体３０を掃除機本体ケース１の内底側に配置することにより、流出口１５０、出口１４９から内部流通口６５に至る狭い空気流路でも空気の流通が妨げられないので、通風部材１４０の通風機能を十分に機能させることができる。   By arranging the dust removal rotating body 30 on the inner bottom side of the cleaner body case 1 in this way, air flow is not hindered even in a narrow air flow path from the outlet 150 and the outlet 149 to the internal circulation port 65. The ventilation function of the ventilation member 140 can sufficiently function.

また、除塵回転体３０は、集塵室３の後側と電動送風機２６の前側との間に設けられている内部流通口６５の下部より下方に配置したので、内部流通口６５を流れる空気の妨げがなく、電動送風機２６の吸引が良く行なわれる。   In addition, since the dust removal rotating body 30 is disposed below the lower part of the internal circulation port 65 provided between the rear side of the dust collection chamber 3 and the front side of the electric blower 26, the air flowing through the internal circulation port 65 There is no hindrance and the electric blower 26 is sucked well.

また、濾過フィルタ１４８は、ここを流れる空気に含まれる細塵を捕集する。このため、電気掃除機から排出される排気は浄化される。更に濾過フィルタ１４８は消臭効果もあり、排出される排気は集塵袋２５内の塵埃に付着していると思われる臭いを除去する効果もある。   Moreover, the filtration filter 148 collects fine dust contained in the air flowing here. For this reason, the exhaust discharged from the vacuum cleaner is purified. Further, the filter 148 has a deodorizing effect, and the exhausted exhaust has an effect of removing odors that are considered to be attached to the dust in the dust bag 25.

なお、通風部材を下側に設けたときには、除塵回転体を上側に配置する。通風部材と除塵回転体は、反対側の位置に配置することにより、通風部材の通風機能が生かされるのである。   When the ventilation member is provided on the lower side, the dust removal rotating body is disposed on the upper side. By arranging the ventilation member and the dust removal rotating body at positions opposite to each other, the ventilation function of the ventilation member is utilized.
