After being inserted, it is assembled in a configuration that fits into the U groove portion 44 of the partition wall body 43 after insertion. A retaining part 49 that forms a closing surface of a leak hole 45 provided on the bottom surface of the U-groove portion 44 of the partition wall 43 and press-fitting is fitted to the tip of the shaft portion 47. In the above configuration, by operating the knob 46 of the air volume adjusting lever 17, the opening of the leakage hole 45 can be closed according to sliding, and the leakage area can be adjusted. As a result, the suction force on the surface to be cleaned 80 of the suction tool 4 can be adjusted based on the adjustment of the degree of vacuum in the rotating brush chamber 34.

３５は図に示す通り前記回転ブラシ室３４の後方に設けられ、前記塵埃吸引口４２より以降電気掃除機本体１への吸引経路を形成するタービン室である。前記回転ブラシ室３４と同様に、上部材１３及び下部材１２より延設する印籠嵌合部を有した壁面３１、３３で仕切られた空間部であり、吸引経路として構成したものである。主に前記回転ブラシ２２の回転駆動源となるエアータービン３０と、延長管３に接続する為の接続部５４を備えた回転アーム９を配設している。これよりタービン室３５に配設する各種機能手段の構成について説明する。   A turbine chamber 35 is provided at the rear of the rotary brush chamber 34 as shown in the drawing and forms a suction path from the dust suction port 42 to the vacuum cleaner body 1 thereafter. Similar to the rotating brush chamber 34, it is a space portion partitioned by wall surfaces 31 and 33 having stamping fitting portions extending from the upper member 13 and the lower member 12, and is configured as a suction path. An air turbine 30 that mainly serves as a rotational drive source for the rotary brush 22 and a rotary arm 9 having a connection portion 54 for connecting to the extension pipe 3 are disposed. The configuration of various functional means disposed in the turbine chamber 35 will now be described.

３０は、長手方向に延びる複数のブレード３６と、その両端に側壁３７を形成させ略円筒状に形成したエアータービンであり、前記側壁３７中央を貫通かつ片側一方に突出する軸体３８を形成させると共に、回転摩擦抵抗を軽減する為の軸受け部品３９並びに、前記回転ブラシ２２への回転伝達を行う駆動ベルト２５と、その取り付け及び回転減速を狙いとした歯車４０を設けている。前記軸受け部品３９においては、両端に潤滑油を含浸させたメタル軸受け３９−ａを設け、その中間部にはグリス噴入部を有した略円筒の形状に構成させた部品であり、前記軸体３８を回転可能に貫通挿入している。また、その先端には小径歯車４０を軸体３８へ回転不能に圧入固定させ、前記エアータービン３０の回転に動機させ構成にて取り付けられている。この周辺の外郭形状を含めた構成においては、前記エアータービン３０より側面方向に且つ、吸込具４の側端まで突出させた軸受け部品３９の先端に、回転伝達を行う駆動ベルト２５を設け配設することにより、同じくそれら機能手段を覆う保持部を形成した外郭を、吸込具４の側端まで突出させる構成としている。突出させる外郭構成においては、前記機能手段に対し干渉を避ける為の最小限のクリアランスを有し、前記上部材１３並びに下部材１２より延設させた上下２つの外郭により、タービン室３５及び回転ブラシ室３４同様上下部品の狭持嵌合により構成されている。特に吸込具４の前方回転ブラシ２２の側端と、その後方タービン室３５中央より突出した軸受け部品３９の先端とで、連結する駆動ベルト２５らを覆う外郭構成においては、前記機能手段（回転ブラシ２２、タービン室３５、軸受け部品３９、駆動ベルト２５）を４辺とする略四角形配置構成とし、その中央部に外郭を形成しない貫通孔状の空間孔部１４−ａを形成させたものとなっている。   Reference numeral 30 denotes a plurality of blades 36 extending in the longitudinal direction, and an air turbine formed in a substantially cylindrical shape by forming side walls 37 at both ends thereof. At the same time, there are provided a bearing part 39 for reducing rotational frictional resistance, a drive belt 25 for transmitting rotation to the rotary brush 22, and a gear 40 for mounting and reducing the rotation. In the bearing part 39, metal bearings 39-a impregnated with lubricating oil are provided at both ends, and a part having a substantially cylindrical shape having a grease injection part at an intermediate part thereof is provided. Is inserted in a rotatable manner. Further, a small-diameter gear 40 is press-fitted and fixed to the shaft body 38 so as to be non-rotatable at the tip thereof, and is motivated by the rotation of the air turbine 30 and attached in a configuration. In the configuration including the outer shape of the periphery, a drive belt 25 that transmits rotation is provided at the tip of the bearing part 39 that protrudes in the lateral direction from the air turbine 30 to the side end of the suction tool 4. By doing so, it is set as the structure which makes the outer shape which similarly formed the holding part which covers those functional means protrudes to the side end of the suction tool 4. FIG. In the outer shell structure to project, the turbine chamber 35 and the rotating brush are provided by two upper and lower outer shells extending from the upper member 13 and the lower member 12 with a minimum clearance for avoiding interference with the functional means. Like the chamber 34, the upper and lower parts are sandwiched and fitted. In particular, in the outer shell structure that covers the drive belt 25 and the like connected by the side end of the front rotating brush 22 of the suction tool 4 and the tip of the bearing part 39 protruding from the center of the rear turbine chamber 35, the functional means (rotating brush) 22, the turbine chamber 35, the bearing component 39, and the drive belt 25) are arranged in a substantially square shape with four sides, and a through-hole-like space hole portion 14-a that does not form an outer shell is formed at the center thereof. ing.

また、前記吸込具４の中央タービン室３５を境に、相対した位置に同じく貫通孔状の空間孔部１４−ｂを有した外郭部においては、内部に機能手段を配設させないものの、吸込具持ち上げ時の（所謂空中状態における）左右の質量バランス違いによる傾きを防止するための外郭部位として構成させている。また、その前記空間孔部１４−ａ、１４−ｂは、図８に示す様に、家屋内における吊り下げ収納用ヒンジＡ等への引っ掛けを可能としてい
る。回転アーム９は、タービン室３５内全幅に渡り、両端に回転軸５１、５２を設けた略円筒状の風洞部５３に、掃除機本体１との接続手段となる延長管３への着脱を可能とした接続部５４を構成し、前記上部材１３並びに下部材１２による上下からの壁面３１、３３の狭持による軸支持構成によって、回動自在に配設保持されている。また前記風洞部５３の内側には、前記エアータービン３０を配設している。その配設については、エアータービン３０より片側に突出する軸体３８並びに、軸受け部品３９を前記回動アーム９の回転軸５２内に貫通させ、連続回転可能とし、回転アーム９は前記吸込具４上部材１３の食い切り範囲内５５で前記接続部５４の当接をもって回動止点を決定し、上下回動自在に同軸構成として配設している。 Further, in the outer portion having the through hole-like space hole portion 14-b at the opposite position with the central turbine chamber 35 of the suction tool 4 as a boundary, although no functional means is disposed inside, the suction tool It is configured as an outer portion for preventing an inclination due to a difference in mass balance between right and left (in a so-called aerial state) during lifting. Further, as shown in FIG. 8, the space holes 14-a and 14-b can be hooked to a hanging storage hinge A or the like in the house. The rotary arm 9 can be attached to and detached from the extension pipe 3 serving as a connection means to the cleaner body 1 in a substantially cylindrical air channel portion 53 provided with rotary shafts 51 and 52 at both ends over the entire width of the turbine chamber 35. The connecting portion 54 is configured and is rotatably arranged and held by a shaft support structure in which the upper wall 13 and the lower member 12 hold the wall surfaces 31 and 33 from above and below. Further, the air turbine 30 is disposed inside the wind tunnel portion 53. With respect to the arrangement, the shaft body 38 projecting to one side from the air turbine 30 and the bearing part 39 are passed through the rotating shaft 52 of the rotating arm 9 so that the rotating arm 9 can be continuously rotated. The rotation stop point is determined by the contact of the connecting portion 54 within the cut-off range 55 of the upper member 13, and is arranged as a coaxial structure so as to be rotatable up and down.

タービン室３５内下面には、吸込具４の下部材１２を貫通する格子状孔とした第２吸引口２０を設けている。第２吸引口２０は、被掃除面８０への吸込具４接地状態にて閉鎖されるものであり、吸込具４の持ち上げ時には、閉鎖状態から開放状態となり外気を吸引する。また、第２吸引口２０は前記エアータービン３０と相対しない位置に形成させたことにより、前記吸引された外気はエアータービン３０を通過しない経路８１を辿る為、単に前記塵埃吸込口４２及びエアータービン３０を通過する経路風量８２の減圧を作用するものとなる。すなわち回転ブラシ２２の回転駆動手段であるエアータービン３０の駆動力低下を行い、吸込具４の持ち上げ時に露出する回転ブラシ２２の回転数を同様低下せる効果を生み出すものとなっている。これは、所謂危険性の軽減を図る安全装置的な役割を果たす構成部位である。   A second suction port 20, which is a lattice-like hole penetrating the lower member 12 of the suction tool 4, is provided on the inner lower surface of the turbine chamber 35. The second suction port 20 is closed when the suction tool 4 is grounded to the surface 80 to be cleaned. When the suction tool 4 is lifted, the second suction port 20 is changed from the closed state to the open state and sucks outside air. Further, since the second suction port 20 is formed at a position not facing the air turbine 30, the sucked outside air follows a path 81 that does not pass through the air turbine 30, so that the dust suction port 42 and the air turbine are simply used. The pressure reduction of the path | route air volume 82 which passes 30 acts. That is, the driving force of the air turbine 30 that is the rotation driving means of the rotating brush 22 is reduced, and the effect of similarly reducing the number of rotations of the rotating brush 22 exposed when the suction tool 4 is lifted is produced. This is a component that plays a role of a safety device for reducing the risk.

また、前記第２吸引口２０を形成した下部材１２の外郭側、被掃除面８０に対面する下面周囲には、軟質材からなるブラシ毛で構成した壁状部材６２を配設している。前記壁状部材６２は、硬質な木床等の被掃除面８０へ吸込み具４を接地させた状態において、発生するローラー３２高さ分の隙間６３に伴う閉鎖不足を補うものであり、前記ブラシ長さ６４をローラー３２高さよりも長く形成し配設されている。被掃除面８０への接地状態における吸込具４の集塵性能においては、前記第２吸引口２０の閉鎖レベルに伴い吸塵作用に繋がる真空度が高くなることから、より閉鎖レベルの向上が要求されるものである。   A wall-like member 62 made of soft bristle is disposed around the outer surface of the lower member 12 in which the second suction port 20 is formed, and around the lower surface facing the surface to be cleaned 80. The wall-shaped member 62 compensates for the shortage of closure due to the gap 63 corresponding to the height of the roller 32 generated when the suction tool 4 is grounded to the surface to be cleaned 80 such as a hard wooden floor. The length 64 is formed longer than the roller 32 height. In the dust collection performance of the suction tool 4 in a grounded state with respect to the surface to be cleaned 80, the degree of vacuum that leads to the dust suction action increases with the closing level of the second suction port 20, so that an improvement in the closing level is required. Is.

（実施の形態２）
次に、本発明の実施の形態２における吸込具の構成について、図９及び図１０を用いて説明する。図９に示すように、大きくは前記実施の形態１と同一の構成であり、一部上部材１３並びに下部材１２を貫通させ、吸込具４中央のタービン室３５横左右２箇所に設けた空間孔部１４−ａ、１４−ｂにおいて、内側輪郭部に軟質材で構成するガイド体９１を設けた構成としている。その詳細な構成においては、図１０に示す様に、断面形状を略Ｈ状に形成したガイド体９１の上下溝部９２、９３を、タービン室３５側面から突出し吸込具４の側端より前方の回転ブラシ室３４に連結させてなる外郭部の上部材１３、並びに下部材１２に狭持嵌合させて取り付けを行う構成としている。特にその取り付け範囲においては、前記貫通孔状の空間孔部１４−ａ、１４−ｂ内側輪郭部全周に渡り配設するものとなっている。この構成における作用については、実施の形態１に記載した同様家屋内における吊り下げ収納用ヒンジ等の引っ掛けを可能とする事に加え、前記ヒンジ等の引っ掛け部との間に軟質材で構成させたガイド体９１が介在することにより、干渉による吸込具４への傷つき防止を達成させるものとなる。 (Embodiment 2)
Next, the structure of the suction tool in Embodiment 2 of this invention is demonstrated using FIG.9 and FIG.10. As shown in FIG. 9, the structure is largely the same as that of the first embodiment, and a part of the upper member 13 and the lower member 12 are penetrated, and the space provided in two places on the left and right sides of the turbine chamber 35 in the center of the suction tool 4. In the holes 14-a and 14-b, a guide body 91 made of a soft material is provided in the inner contour portion. In the detailed configuration, as shown in FIG. 10, the upper and lower groove portions 92 and 93 of the guide body 91 having a substantially H-shaped cross section project from the side surface of the turbine chamber 35 and rotate forward from the side end of the suction tool 4. The upper member 13 and the lower member 12 of the outer portion connected to the brush chamber 34 are nipped and fitted to be attached. In particular, in the attachment range, the through hole-like space hole portions 14-a and 14-b are arranged over the entire inner contour portion. As for the operation in this configuration, in addition to enabling the hanging storage hinges and the like in the house as described in the first embodiment, a soft material is formed between the hinges and the like. By interposing the guide body 91, the suction tool 4 can be prevented from being damaged by interference.

（実施の形態３）
次に、本発明の実施の形態３における吸込具の構成について、図１１及び図１２を用いて説明する。特に主体的な部品並びに配置構成においては、前記実施の形態１と同一の構成であり、一部変更する構成について以下に説明する。上部材１３並びに下部材１２を貫通させ、吸込具４中央のタービン室３５横左右２箇所に設けた空間孔部１４−ａ、１４−ｂにおいて、閉鎖面１０１を形成し吸込具４の外郭上方並びに下方が凹部１０２、１０３
を形成する構成とし、前記外郭上方凹部１０２の回転ブラシ室３４壁面に貫通口１０７並びに開閉自在となる蓋部品１０４を取り付けている。前記蓋部品１０４は、図１２に示す様に、回転ブラシ室３４内壁に相対した、湾曲状の板母材に摘み部１０５を形成した部品であり、前記回転ブラシ室３４外郭部の内壁に設けられた保持リブ１０６により摺動可能に狭持して取り付けられている。吸込具４における通常使用時では、常時閉鎖されたものとして使用を行い、使用者の任意適開閉操作時のみ開口するものとしている。この構成における作用については、貫通させた空間孔部１４−ａ、１４−ｂの補強壁として作用するため吸込具４の強度を向上させると共に、前記凹部１０２の形成により、吸込具４前方より吸塵できず使用者が拾い上げた粗大塵埃を一時的に集積する部位として利用可能とし、前記蓋部品１０４の開口により吸引経路との連通が達成される事から、従来吸込具４の取り外しによる延長管等の別途吸塵手段の大口径部からの吸塵処理操作が不要となり、使用性の向上が図れるものとなる。また、任意適開閉操作時のみ開口するものとしている為、通常状態における回転ブラシ室３４での真空度劣化に対しても防止する構成となり、集塵性能劣化の発生も無いものとなる。 (Embodiment 3)
Next, the structure of the suction tool in Embodiment 3 of this invention is demonstrated using FIG.11 and FIG.12. In particular, the main components and the arrangement configuration are the same as those in the first embodiment, and a configuration that is partially changed will be described below. The upper member 13 and the lower member 12 are penetrated, and the closed surface 101 is formed in the space holes 14-a and 14-b provided in two places on the left and right sides of the turbine chamber 35 in the center of the suction tool 4, and the upper part of the suction tool 4 In addition, the lower part is the recesses 102, 103.
The through-hole 107 and the lid part 104 that can be opened and closed are attached to the wall surface of the rotating brush chamber 34 of the outer upper recess 102. As shown in FIG. 12, the lid part 104 is a part in which a knob 105 is formed on a curved plate base material facing the inner wall of the rotating brush chamber 34, and is provided on the inner wall of the outer portion of the rotating brush chamber 34. The holding rib 106 is attached so as to be slidable. At the time of normal use in the suction tool 4, it is used as being always closed, and is opened only at the time of the user's arbitrary opening / closing operation. With respect to the operation in this configuration, the strength of the suction tool 4 is improved because it acts as a reinforcing wall for the space holes 14-a and 14-b that are penetrated, and dust is absorbed from the front of the suction tool 4 by forming the recess 102. Since it is possible to use it as a part for temporarily collecting coarse dust picked up by the user, and the communication with the suction path is achieved by the opening of the lid part 104, an extension pipe or the like by removing the conventional suction tool 4 etc. This eliminates the need for a dust-absorbing treatment operation from the large-diameter portion of the dust-absorbing means, thus improving the usability. In addition, since the opening is made only at the time of arbitrary appropriate opening and closing operation, it is configured to prevent the degree of vacuum in the rotating brush chamber 34 in the normal state, and the dust collection performance is not deteriorated.

（実施の形態４）
次に、本発明の実施の形態４における吸込具の構成について、図１３及び図１４を用いて説明する。主体的な部品並びに配置構成においては、前記実施の形態３と同一の構成であり、一部変更する構成について以下に説明する。前記外郭上方凹部１０２のタービン室３５の壁面に貫通口１１５並びに開閉自在となる蓋部品１１０を取り付けている。前記蓋部品１１０は、図１４に示す様に、タービン室３５内壁に相対した、板状の母材に摘み部１１１を形成した部品であり、前記タービン室３５外郭部の内壁に設けられた保持リブ１１２により摺動可能に狭持して取り付けられている。吸込具４における通常使用時は、閉鎖しておき、使用者の必要に応じた操作によりのみ開口するものである。この構成における作用については、前記実施の形態３と略同様であるが、一点吸込口に連通する事に比べ、真空度の高い部位での別途投入口の形成となるため、より強い吸塵作用を得ることになり、より使用性の向上が図れるものとなる。 (Embodiment 4)
Next, the structure of the suction tool in Embodiment 4 of this invention is demonstrated using FIG.13 and FIG.14. The main components and the arrangement configuration are the same as those in the third embodiment, and a configuration that is partially changed will be described below. A through-hole 115 and a lid part 110 that can be opened and closed are attached to the wall surface of the turbine chamber 35 of the outer upper recess 102. As shown in FIG. 14, the lid component 110 is a component in which a knob 111 is formed on a plate-shaped base material, which is opposed to the inner wall of the turbine chamber 35, and is held on the inner wall of the outer portion of the turbine chamber 35. The rib 112 is slidably attached by the rib 112. During normal use of the suction tool 4, it is closed and opened only by an operation according to the needs of the user. The operation in this configuration is substantially the same as in the third embodiment, but compared to communicating with a one-point suction port, a separate inlet is formed at a site with a high degree of vacuum. Thus, the usability can be further improved.

以上のように、本発明にかかる電気掃除機もしくは電気掃除用吸込具は、小型軽量化を基に、収納性並びに粗大塵埃処理ができるので、使用性を向上させる等の用途にも適用できる。   As described above, since the vacuum cleaner or the vacuum cleaner according to the present invention can be stored and treated with coarse dust on the basis of the reduction in size and weight, it can be applied to uses such as improving usability.
