底部７９ａａと周壁部７９ａｂとの境界部分における前端側および後端側は滑らかに湾曲している。
底部７９ａａと周壁部７９ａｂとの前端側境界部分の近傍であって左右の外面（凸曲面部）には、左右一対の起毛布７９ｊが設けられている。吸込口体７０を前後方向に移動させる際、これらの起毛布７９ｊは被清掃面Ｆ上で摺接しながら支持枠体７９の前端側を支持する（図７参照）。なお、左右一対の起毛布７９ｊの替わりに、回転自在な左右一対の前輪を用いてもよい。 The front end side and the rear end side at the boundary portion between the bottom portion 79aa and the peripheral wall portion 79ab are smoothly curved.
A pair of left and right raised cloths 79j are provided on the left and right outer surfaces (convex curved surface portions) in the vicinity of the front end side boundary portion between the bottom portion 79aa and the peripheral wall portion 79ab. When the suction port 70 is moved in the front-rear direction, these raised cloths 79j support the front end side of the support frame 79 while sliding on the surface F to be cleaned (see FIG. 7). Instead of the pair of left and right brushed cloths 79j, a pair of rotatable front wheels on the left and right may be used.

支持枠体７９において、後方突出支持部７９ｂは、前支持部７９ａの底部７９ａａにおける切欠き部７９ａｄの位置から後方へ延びた支持板部７９ｂａと、支持板部７９ｂａの左右に設けられた左右一対の車輪保持部７９ｂｂと、左右一対の車輪保持部７９ｂｂに左右方向の同一軸心を中心として回転自在に取り付けられた支持回転体としての左右一対の後輪７９ｂｃとを有する。吸込口体７０を前後方向に移動させる際、これらの後輪７９ｂｃは被清掃面Ｆ上で回動しながら支持枠体７９の後端側を支持する（図７参照）。なお、支持回転体としては、左右一対の後輪７９ｂｃの替わりに、支持板部７９ｂａに回転自在に設けたローラを用いてもよい。 In the support frame body 79, the rear protruding support portion 79b includes a support plate portion 79ba extending rearward from the position of the notch portion 79ad in the bottom portion 79aa of the front support portion 79a and a pair of left and right sides provided on the left and right sides of the support plate portion 79ba. Has a pair of left and right wheel holding portions 79bb and a pair of left and right rear wheels 79bc as support rotating bodies rotatably attached to a pair of left and right wheel holding portions 79bb about the same axis in the left-right direction. When the suction port 70 is moved in the front-rear direction, these rear wheels 79bc support the rear end side of the support frame 79 while rotating on the surface F to be cleaned (see FIG. 7). As the support rotating body, instead of the pair of left and right rear wheels 79bc, a roller rotatably provided on the support plate portion 79ba may be used.

支持板部７９ｂａは、左右の後輪７９ｂｃよりも後方へ突出しており、この後輪７９ｂｃよりも後方へ突出した部分は踏み板部７９ｂａａとなっている。
この踏み板部７９ｂａａは、前記支持枠体の前記吸込口本体への着脱時に踏んで支持枠体７９を被清掃面Ｆ上に押さえつけるためのものである。これにより、支持枠体７９の吸込口本体７１への着脱時に踏み板部７９ｂａａを足で踏んで支持枠体７９を固定することができるため、着脱を迅速かつ容易に行うことができる。この際、使用者は掃除機本体１０のハンドル部２３（図２参照）を持って清掃するときの姿勢のままで踏み板部７９ｂａａを容易に踏むことができる。
なお、踏み板部７９ｂａａは、後方突出支持部７９ｂの支持板部７９ｂａの後端に設ける替わりに、前支持部７９ａの底部７９ａａの左側後端に設けて左側の後輪７９ｂｃよりも左側に突出させてもよく、あるいは底部７９ａａの右側後端に設けて右側の後輪７９ｂｃよりも右側に突出させてもよい。 The support plate portion 79ba protrudes rearward from the left and right rear wheels 79bc, and the portion protruding rearward from the rear wheel 79bc is the tread plate portion 79baa.
The tread plate portion 79baa is for pressing the support frame body 79 onto the surface to be cleaned F by stepping on the support frame body when the support frame body is attached to and detached from the suction port main body. As a result, when the support frame body 79 is attached to and detached from the suction port main body 71, the support frame body 79 can be fixed by stepping on the tread plate portion 79baa with a foot, so that the support frame body 79 can be attached and detached quickly and easily. At this time, the user can easily step on the tread plate portion 79baa while holding the handle portion 23 (see FIG. 2) of the vacuum cleaner main body 10 and keeping the posture when cleaning.
The tread plate portion 79baa is provided at the left rear end of the bottom portion 79aa of the front support portion 79a instead of being provided at the rear end of the support plate portion 79ba of the rear protruding support portion 79b so as to project to the left side of the left rear wheel 79bc. Alternatively, it may be provided at the right rear end of the bottom 79aa and may be projected to the right side of the right rear wheel 79bc.

このように構成された支持枠体７９において、前支持部７９ａは、底部７９ａａ、周壁部７９ａｂおよび前端上部７９ａｃによって略上方開口容器形に形成されている（図４参照）。
この略上方開口容器形の前支持部７９ａに上方から吸込口本体７１の吸引部７２の前部７２ｘａを嵌め込んで装着すると、図６と図７に示すように、吸込口本体７１の前端側の左右の起毛布７２ｊが支持枠体７９の底部７９ａａ上に載り、かつ、吸込口本体７１の後部ローラ７３が支持枠体７９の後端側の支持板部７９ｂａ上に載る。なお、この装着は、支持枠体７９が動かないよう踏み板部７９ｂａａを踏みながら行ってもよい。 In the support frame body 79 configured as described above, the front support portion 79a is formed in a substantially upward opening container shape by the bottom portion 79aa, the peripheral wall portion 79ab, and the front end upper portion 79ac (see FIG. 4).
When the front portion 72xa of the suction portion 72 of the suction port main body 71 is fitted and attached to the front support portion 79a of the substantially upper opening container shape from above, as shown in FIGS. 6 and 7, the front end side of the suction port main body 71 is attached. The left and right raised cloths 72j are placed on the bottom portion 79aa of the support frame body 79, and the rear roller 73 of the suction port main body 71 is placed on the support plate portion 79ba on the rear end side of the support frame body 79. In addition, this mounting may be performed while stepping on the tread plate portion 79baa so that the support frame body 79 does not move.

装着状態においては、吸込口本体７１の吸引部７２の前部７２ｘａにおける周囲部７２ｃの左右側面および後端面が、支持枠体７９の前支持部７９ａの周壁部７９ａｂにおける左右内側面および後端内面に適度に圧接する。これにより、踏み板部７９ｂａａを踏まずに吸込口本体７１を持ち上げると、支持枠体７９が吸込口本体７１から不意に脱落することがない。なお、踏み板部７９ｂａａを踏みながら吸込口本体７１を持ち上げれば、吸込口本体７１が支持枠体７９から簡単に離脱する。 In the mounted state, the left and right side surfaces and the rear end surface of the peripheral portion 72c in the front portion 72xa of the suction portion 72 of the suction port main body 71 are the left and right inner side surfaces and the rear end inner surface of the peripheral wall portion 79a of the front support portion 79a of the support frame body 79. Press appropriately. As a result, when the suction port main body 71 is lifted without stepping on the tread plate portion 79baa, the support frame body 79 does not suddenly fall off from the suction port main body 71. If the suction port main body 71 is lifted while stepping on the tread plate portion 79baa, the suction port main body 71 is easily detached from the support frame body 79.

支持枠体７９が吸込口本体７１に装着された状態において、吸込口本体７１の吸込口７２ａと支持枠体７９の開口部７９ｑとは互いに重なっており（図７参照）、吸込口本体７１の回転清掃体７４が被清掃面Ｆ側に露出する。すなわち、回転清掃体７４のブラシ７４ｂは、支持枠体７９が吸込口本体７１に装着された状態において、被清掃面Ｆに達する突出寸法を有している。したがって、支持枠体７９が吸込口本体７１に装着された吸込口体７０によっても被清掃面Ｆ上のダストを回転する回転清掃体７４にて掻き込みながら吸引除去することができ、特に、毛足の長い絨毯（ラグ）上を清掃する場合に適している。 In a state where the support frame body 79 is attached to the suction port main body 71, the suction port 72a of the suction port main body 71 and the opening 79q of the support frame body 79 overlap each other (see FIG. 7), and the suction port main body 71 The rotary cleaning body 74 is exposed on the F side of the surface to be cleaned. That is, the brush 74b of the rotary cleaning body 74 has a protruding dimension that reaches the surface to be cleaned F when the support frame body 79 is attached to the suction port main body 71. Therefore, the support frame body 79 can also be sucked and removed while being scraped by the rotating cleaning body 74 that rotates the dust on the surface to be cleaned F by the suction port body 70 attached to the suction port main body 71. Suitable for cleaning long-legged carpets (rugs).

図７では、支持枠体７９が吸込口本体７１に装着された吸込口体７０をフラットな被清掃面Ｆ上に載置した場合を図示しており、被清掃面Ｆがラグであれば毛先が回転清掃体７４に適度に接触する。つまり、吸込口本体７１をラグ上に載置すると、回転清掃体７４とラグとの摩擦抵抗が大きくなり、かつ、ラグの毛先が吸込口７２ａ内に吸い込まれて吸込口本体７１を前後移動させにくくなる。これに対して、ラグと吸込口本体７１との間に支持枠体７９を介在させることにより、回転清掃体７４とラグとの摩擦抵抗が適度に低減し、かつ、ラグの毛先が吸込口７２ａ内に吸い込まれにくくなるため、吸込口本体７１の前後移動がスムーズとなる。さらに、吸込口本体７１の後部ローラ７３よりも直径が大きい支持枠体７９の左右一対の後輪７９ｂｃはラグの長い毛に埋まりにくいため、ラグ上でスムーズに支持枠体７９を前後移動させることができる。このようなことから、ラグ上の清掃には、吸込口本体７１単体よりも支持枠体７９を介在させた方が適している。 FIG. 7 shows a case where the suction port 70 mounted on the suction port main body 71 is placed on a flat surface to be cleaned F, and if the surface F to be cleaned is a lug, hair is shown. The tip appropriately contacts the rotary cleaning body 74. That is, when the suction port main body 71 is placed on the lug, the frictional resistance between the rotary cleaning body 74 and the lug becomes large, and the bristles of the lug are sucked into the suction port 72a to move the suction port main body 71 back and forth. It becomes difficult to make it. On the other hand, by interposing the support frame body 79 between the lug and the suction port main body 71, the frictional resistance between the rotary cleaning body 74 and the lug is appropriately reduced, and the bristles of the lug are the suction port. Since it is difficult to be sucked into the 72a, the suction port main body 71 can be smoothly moved back and forth. Further, since the pair of left and right rear wheels 79bc of the support frame 79 having a diameter larger than that of the rear roller 73 of the suction port main body 71 is difficult to be buried in the long hair of the lug, the support frame 79 should be smoothly moved back and forth on the lug. Can be done. Therefore, for cleaning on the lug, it is more suitable to interpose the support frame 79 than the suction port main body 71 alone.

また、支持枠体７９を吸込口本体７１に装着したことにより、図１に示すように、吸込口本体７１に接続されている延長管６０および掃除機本体１０を起立状態に安定的に維持することが可能となる。例えば、本実施形態では、延長管６０を被清掃面Ｆに対して９０°を超える角度で起立させ、このときの掃除機本体１０全体の重心が、支持枠体７９の平面的な中央位置（支持枠体７９の前後方向の中間位置かつ左右方向の中間位置）の概ね直上に位置することで、延長管６０および掃除機本体１０を起立状態に安定的に維持することが可能となっている。このような安定的な起立状態の維持は、吸込口本体７１の前端よりも支持枠体７９の前端を前方へ突出させることにより可能となっている。 Further, by attaching the support frame body 79 to the suction port main body 71, as shown in FIG. 1, the extension pipe 60 and the vacuum cleaner main body 10 connected to the suction port main body 71 are stably maintained in an upright state. It becomes possible. For example, in the present embodiment, the extension pipe 60 is erected at an angle exceeding 90 ° with respect to the surface to be cleaned F, and the center of gravity of the entire vacuum cleaner body 10 at this time is the plane center position of the support frame body 79 ( By being located approximately directly above the support frame body 79 (intermediate position in the front-rear direction and intermediate position in the left-right direction), the extension pipe 60 and the vacuum cleaner body 10 can be stably maintained in an upright state. .. Maintaining such a stable upright state is possible by projecting the front end of the support frame body 79 forward from the front end of the suction port main body 71.

そのため、例えば、ラグ上の清掃を一旦中断するときに、電気掃除機１をラグ上に寝かせることなく起立状態（自立状態）で放置しておくことができ、清掃を再開する際には使用者は屈むことなく（腰に負担をかけずに）立ったままの楽な姿勢で掃除機本体１０のハンドル部２３を掴むことができる。さらに、電気掃除機１を起立状態で収納する際、専用の大きなスタンド台が不要となるため、収納場所に占める設置面積（収納スペース）を削減することができる。さらに、スタンド台は掃除に直接関わるものではないため、ユーザーによっては電気掃除機を収納するためだけにスタンド台を購入するにはコスト負担が大きいが、この電気掃除機１によれば使用者がスタンド台を購入するときのコスト負担がなくなる。 Therefore, for example, when the cleaning on the rug is temporarily interrupted, the vacuum cleaner 1 can be left in an upright state (independent state) without lying on the rug, and the user can restart the cleaning. Can grasp the handle portion 23 of the vacuum cleaner body 10 in a comfortable posture while standing without bending down (without putting a burden on the waist). Further, when the vacuum cleaner 1 is stored in an upright state, a large dedicated stand is not required, so that the installation area (storage space) occupying the storage space can be reduced. Further, since the stand stand is not directly related to cleaning, it is costly for some users to purchase the stand stand only for storing the vacuum cleaner, but according to this vacuum cleaner 1, the user can use it. Eliminates the cost burden of purchasing a stand.

一方、フローリングや畳や毛足の短い絨毯等の被清掃面Ｆ上を清掃する際は、吸込口本体７１から支持枠体７９を取り外し、支持枠体７９よりも小型で小回りがきく吸込口本体７１（図２参照）を単独で用いて被清掃面Ｆ上を清掃すればよく、狭い隙間の清掃に適している。また、支持枠体７９を装着していると、吸込口本体７１の前端よりも支持枠体７９の前端が前方に突出して壁際を清掃しにくいため、吸込口本体７１単独の方が壁際の清掃にも適している。 On the other hand, when cleaning the surface F to be cleaned such as flooring, tatami mats, and carpets with short hair, the support frame 79 is removed from the suction port body 71, and the suction port body is smaller and has a smaller turn than the support frame body 79. 71 (see FIG. 2) may be used alone to clean the surface F to be cleaned, which is suitable for cleaning narrow gaps. Further, when the support frame body 79 is attached, the front end of the support frame body 79 protrudes forward from the front end of the suction port main body 71 and it is difficult to clean the wall side. Therefore, the suction port main body 71 alone is used for cleaning the wall side. Also suitable for.

（第２実施形態）
図８は第２実施形態の吸込口体における吸込口本体に支持枠体を装着した状態を示す斜視図である。なお、図８において、図６中の要素と同様の要素には同一の符号を付している。
第２実施形態の吸込口体１７０は、支持枠体１７９の構成が第１実施形態の吸込口体７０における支持枠体７９とは異なること以外は、第１実施形態と概ね同様に構成されている。つまり、第２実施形態の吸込口体１７０は、支持枠体１７９と、第１実施形態で説明した吸込口本体７１とを備える。
以下、第２実施形態における第１実施形態とは異なる点を主に説明する。 (Second Embodiment)
FIG. 8 is a perspective view showing a state in which the support frame body is attached to the suction port main body in the suction port body of the second embodiment. In FIG. 8, the same elements as those in FIG. 6 are designated by the same reference numerals.
The suction port body 170 of the second embodiment is configured substantially in the same manner as the first embodiment except that the structure of the support frame body 179 is different from that of the support frame body 79 in the suction port body 70 of the first embodiment. There is. That is, the suction port body 170 of the second embodiment includes the support frame body 179 and the suction port main body 71 described in the first embodiment.
Hereinafter, the points different from the first embodiment in the second embodiment will be mainly described.

図８に示すように、第２実施形態の場合、支持枠体１７９は、第１実施形態の支持枠体７９（図４〜図７参照）における開口部７９ｑよりも前端側対応部分が省略された形状を有している。つまり、支持枠体１７９の前支持部１７９ａは平面的に視てＵ字形をしており、Ｕ字形の内側領域に前方へ解放した（切り欠かれた）形状の開口部が設けられている。
したがって、吸込口本体７１を支持枠体１７９に装着した状態では、吸込口本体７１のバンパー７２ｙが前方へ露出している。 As shown in FIG. 8, in the case of the second embodiment, in the support frame body 179, the front end side corresponding portion is omitted from the opening 79q in the support frame body 79 (see FIGS. 4 to 7) of the first embodiment. Has a different shape. That is, the front support portion 179a of the support frame body 179 has a U-shape when viewed in a plane, and an opening having a shape open forward (notched) is provided in the inner region of the U-shape.
Therefore, when the suction port main body 71 is attached to the support frame body 179, the bumper 72y of the suction port main body 71 is exposed forward.

このように構成された吸込口体１７０によれば、第１実施形態の吸込口体７０と同様に、支持枠体１７９の吸込口本体７１に対する着脱と、延長管６０および掃除機本体１０（図１参照）の起立状態の維持とを行うことができる。
また、支持枠体１７９を装着した吸込口本体７１によるラグ上の清掃にも適している。また、支持枠体１７９は前端側が解放した形状であるため、例えば、壁際にある被清掃面付近まで垂れたロングカーテンの裾に吸込口本体７１の前端を近づけて、裾に付着したダストを吸引することも可能である。
さらに、支持枠体１７９は前端側が解放した形状であることから、支持枠体１７９の収納場所に占める設置面積（収納スペース）をより削減することができる。 According to the suction port body 170 configured in this way, like the suction port body 70 of the first embodiment, the support frame body 179 is attached to and detached from the suction port main body 71, and the extension pipe 60 and the vacuum cleaner main body 10 (FIG. It is possible to maintain the standing state of 1).
It is also suitable for cleaning on the lug by the suction port main body 71 to which the support frame body 179 is attached. Further, since the support frame 179 has a shape in which the front end side is open, for example, the front end of the suction port main body 71 is brought close to the hem of the long curtain hanging near the surface to be cleaned near the wall to suck the dust adhering to the hem. It is also possible to do.
Further, since the support frame body 179 has a shape in which the front end side is open, the installation area (storage space) occupied in the storage space of the support frame body 179 can be further reduced.

（第３実施形態）
第１実施形態の吸込口体７０において、吸込口本体７１に支持枠体７９を装着したときに装着状態をロックするロック機構を設けてもよい。例えば、支持枠体７９の後端側の支持板部７９ｂａに爪部を設け、かつ、吸込口本体７１の後端側の後方突出部７２ｘｂに凸形または凹形の係止部を設けてロック機構を構成してもよい。この場合、装着時に爪部が係止部に係止してロックし、踏み板部７９ｂａａを踏みながら吸込口本体７１を持ち上げると爪部から係止部が外れてロックが解除され、支持枠体７９から吸込口本体７１を分離させることができる。
あるいは、吸込口本体７１を掴む回動可能なフックを支持枠体７９に設け、このフックが、装着時に吸込口本体７１を掴むことで、吸込口本体７１と支持枠体７９とを一体化させるようにしてもよい。このフックは、踏板を踏むことで吸込口本体７１を離すように回動する構成となっている。よって、支持枠体７９からの吸込口本体７１の取り外しが容易になる。 (Third Embodiment)
In the suction port body 70 of the first embodiment, a lock mechanism may be provided to lock the mounted state when the support frame body 79 is mounted on the suction port main body 71. For example, a claw portion is provided on the support plate portion 79ba on the rear end side of the support frame body 79, and a convex or concave locking portion is provided on the rear protruding portion 72xb on the rear end side of the suction port main body 71 to lock. A mechanism may be configured. In this case, the claw portion is locked to the locking portion and locked at the time of mounting, and when the suction port main body 71 is lifted while stepping on the tread plate portion 79baa, the locking portion is released from the claw portion and the lock is released, and the support frame body 79 is released. The suction port main body 71 can be separated from the suction port main body 71.
Alternatively, a rotatable hook for gripping the suction port main body 71 is provided on the support frame body 79, and this hook grips the suction port main body 71 at the time of mounting to integrate the suction port main body 71 and the support frame body 79. You may do so. This hook is configured to rotate so as to separate the suction port main body 71 by stepping on the tread plate. Therefore, the suction port main body 71 can be easily removed from the support frame body 79.

（他の実施形態）
・第１〜第３実施形態では吸込口本体７１における回転清掃体７４は駆動モータ７５にて回転する場合を例示したが、タービン駆動によって回転清掃体７４を回転させるようにしてもよい。また、回転清掃体７４は、ブラシ７４ｂとブレードとが混在する回転ブラシであってもよく、あるいは全てのブラシ７４ｂをブレードに置き換えた回転ブレードであってもよい。また、吸込口本体７１は、回転清掃体７４およびその駆動部を省略したものであってもよい。 (Other embodiments)
-In the first to third embodiments, the case where the rotary cleaning body 74 in the suction port main body 71 is rotated by the drive motor 75 is exemplified, but the rotary cleaning body 74 may be rotated by the turbine drive. Further, the rotary cleaning body 74 may be a rotary brush in which the brush 74b and the blade are mixed, or may be a rotary blade in which all the brushes 74b are replaced with blades. Further, the suction port main body 71 may omit the rotary cleaning body 74 and its driving unit.

・第１〜第３実施形態ではスティック型のコードレス電気掃除機を例示したが、本発明の吸込口体はキャニスター型の電気掃除機に用いられてもよい。この場合、例えば、吸込口本体に支持枠体を装着した吸込口体を用いてキャニスター型電気掃除機にて毛足の長い絨毯（ラグ）を清掃しているときに、延長管を起立させた状態で清掃を中断することができる。つまり、清掃を中断する際に延長管を床面に寝かせずに起立させておくことができるため、清掃を再開するときに使用者が屈まずに（腰に負担をかけずに）延長管の上方のハンドルを掴むことができる。また、収納場所においても、壁に立てかけることなく延長管を起立させておくことができる。 -Although the stick-type cordless vacuum cleaner is exemplified in the first to third embodiments, the suction port body of the present invention may be used for a canister-type vacuum cleaner. In this case, for example, the extension pipe was erected while cleaning a long-haired carpet (rug) with a canister type vacuum cleaner using a suction port body in which a support frame body was attached to the suction port body. Cleaning can be interrupted in the state. In other words, when cleaning is interrupted, the extension pipe can be erected without lying on the floor, so that the user does not bend (without straining the waist) when restarting cleaning. You can grab the upper handle. Further, even in the storage place, the extension pipe can be erected without leaning against the wall.

（まとめ）
本発明の電気掃除機の吸込口体は、被清掃面上を走行可能な吸込口本体と、前記吸込口本体に着脱可能に装着されて前記吸込口本体と共に被清掃面上を走行可能な支持枠体とを備え、
前記吸込口本体は、左右方向に延びる吸込口を底部に有する吸引部と、前記吸引部に左右方向の軸心を中心として回動可能に結合した接続管部とを有し、
前記支持枠体は、前記吸込口本体との装着状態において、前記吸込口を被清掃面側へ露出させる開口部を有すると共に、前記接続管部に直接または延長管を介して接続された掃除機本体の被清掃面上での起立状態を維持可能に構成されたものである。 (summary)
The suction port body of the electric vacuum cleaner of the present invention has a suction port body that can travel on the surface to be cleaned, and a support that is detachably attached to the suction port body and can travel on the surface to be cleaned together with the suction port body. Equipped with a frame,
The suction port main body has a suction portion having a suction port extending in the left-right direction at the bottom, and a connecting pipe portion rotatably connected to the suction portion about the axis in the left-right direction.
The support frame has an opening that exposes the suction port to the surface to be cleaned when the suction port is attached to the main body of the suction port, and is connected to the connection pipe portion directly or via an extension pipe. It is configured to be able to maintain an upright state on the surface to be cleaned of the main body.

電気掃除機の吸込口体として、本発明の吸込口体を用いることにより、電気掃除機の収納スペース（収納場所の面積）およびスタンド台の購入コストを削減することができる。
つまり、この吸込口体は、スティック型またはハンディ型の電気掃除機の自立を可能とする（起立状態の維持を可能とする）ものであるため、電気掃除機を起立状態で収納するためのスタンド台が不要となり、スタンド台の購入コストを削減することができる。それに加え、吸込口本体に支持枠体を装着した吸込口体は、毛足の長い絨毯（ラグ）上を清掃するのに適している。このように本発明の吸込口体は、床面清掃時の吸込具であり、スタンド台を兼ねるものでもある。
また、この吸込口体の支持枠体は、スティック型またはハンディ型の電気掃除機の自立（起立）を少なくとも維持できるサイズであればよいため、従来のスタンド台の設置スペースよりも支持枠体を小型化してスティック型またはハンディ型の電気掃除機の収納スペースを削減することができる。 By using the suction port body of the present invention as the suction port body of the electric vacuum cleaner, it is possible to reduce the storage space (area of the storage space) of the electric vacuum cleaner and the purchase cost of the stand stand.
In other words, since this suction port body enables the stick-type or handy-type vacuum cleaner to stand on its own (it enables the maintenance of the standing state), it is a stand for storing the vacuum cleaner in the standing state. The stand is no longer required, and the purchase cost of the stand stand can be reduced. In addition, the suction port body in which the support frame body is attached to the suction port body is suitable for cleaning on a long-haired carpet (rug). As described above, the suction port body of the present invention is a suction tool for cleaning the floor surface and also serves as a stand.
In addition, since the support frame of the suction port should be of a size that can at least maintain the independence (standing) of the stick-type or handy-type vacuum cleaner, the support frame should be larger than the installation space of the conventional stand stand. It can be miniaturized to reduce the storage space for stick-type or hand-held vacuum cleaners.

本発明の電気掃除機の吸込口体は、次のように構成されてもよく、それらが適宜組み合わされてもよい。 The suction port of the vacuum cleaner of the present invention may be configured as follows, or may be combined as appropriate.

・前記吸引部は、前記吸込口を有する前部と、前記前部の左右方向の中間位置から前記接続管部の下を通って後方へ突出する後方突出部とを有し、
前記支持枠体は、前記前部を支持する前支持部と、前記後方突出部を支持するように前記前支持部の左右方向の中間位置から後方へ突出する後方突出支持部とを有するものであってもよい。
この構成によれば、支持枠体の前支持部と後方突出支持部に吸引部の前部と後方突出部を嵌め込んで支持することができる。 The suction portion has a front portion having the suction port and a rear protrusion portion protruding rearward from an intermediate position in the left-right direction of the front portion under the connecting pipe portion.
The support frame has a front support portion that supports the front portion and a rear protrusion support portion that projects rearward from an intermediate position in the left-right direction of the front support portion so as to support the rear protrusion portion. There may be.
