Furthermore, an electric blower 30 is accommodated inside the body portion 11 .

前記胴部１１の外殻体１３について詳述する。前記外殻体１３は、前述した通り、径の異なる部分を有する略円筒状に形成される。具体的には、後述する遠心ファン３２が収容されるファン収容部１６と、後述する電動機３１が収容される電動機収容部１７と、これらの間に設けられた段差部１８とを有する。なお、前記ファン収容部１６は、電動機収容部１７に比べ相対的に太い。即ち、前記電動機収容部１７は、ファン収容部１６に比べ相対的に細い。そして、前記電動機収容部１７は、前記ファン収容部１６の後方に設けられる。また、前記ファン収容部１６と電動機収容部１７と段差部１８は、中心軸線Ｘｂを基準として略同軸状に設けられる。なお、前記中心軸線Ｘｂは、前記電動送風機３０の中心軸線Ｘｍと一致する。また、前記ファン収容部１６の前方には、前記集塵容器４０を受ける受部１９が設けられる。また、前記把持部１２の後端部は、前記電動機収容部１７と一体に連結する。更に、前記把持部１２の前端部は、連結部２０によって前記受部１９と連結する。そして、前記段差部１８の下部１８Ｄには脚部２１が設けられると共に、この脚部２１に取付孔部２２が形成される。更に、この取付孔部２２には、前記電源コード１５のコードブッシュ２３が取り付けられる。このコードブッシュ２３は、自然状態、即ち外力が加わらない状態において、前記中心軸線Ｘｂ及び中心軸線Ｘｍと平行である。 The outer shell 13 of the trunk portion 11 will be described in detail. As described above, the outer shell 13 is formed in a substantially cylindrical shape having portions with different diameters. Specifically, it has a fan housing portion 16 housing a centrifugal fan 32 described later, an electric motor housing portion 17 housing an electric motor 31 described later, and a stepped portion 18 provided therebetween. Incidentally, the fan accommodating portion 16 is relatively thicker than the electric motor accommodating portion 17 . That is, the motor accommodating portion 17 is relatively narrower than the fan accommodating portion 16 . The electric motor housing portion 17 is provided behind the fan housing portion 16 . Further, the fan accommodating portion 16, the electric motor accommodating portion 17, and the stepped portion 18 are provided substantially coaxially with respect to the central axis Xb. The center axis Xb coincides with the center axis Xm of the electric blower 30 . A receiving portion 19 for receiving the dust container 40 is provided in front of the fan accommodating portion 16 . Further, the rear end portion of the holding portion 12 is integrally connected to the electric motor accommodating portion 17 .

A leg portion 21 is provided at the lower portion 18D of the stepped portion 18, and a mounting hole portion 22 is formed in the leg portion 21. As shown in FIG. Furthermore, a cord bush 23 of the power cord 15 is attached to the attachment hole portion 22 . The cord bush 23 is parallel to the central axis Xb and the central axis Xm in a natural state, that is, in a state where no external force is applied.

前記排気口部１４は、円形の排気口２４と、この排気口２４を囲むように設けられた複数（本実施形態では三つ）の接地部としての脚部２５とを有する。なお、これらの脚部２５は、一つの短筒状の脚部としても良い。これらの脚部２５は、全体として前記中心軸線Ｘｂと同軸状に設けられる。そして、これらの脚部２５の外周面には、それぞれ係合凸部２６が前記中心軸線Ｘｂと直交する方向に突出して設けられる。なお、前記各係合凸部２６は、異なる角度間隔で設けられる。第一係合凸部２６１と第二係合凸部２６２の角度間隔はθ１であり、約１２７度である。第二係合凸部２６２と第三係合凸部２６３の角度間隔はθ２であり、約１０２度である。第三係合凸部２６３と第一係合凸部２６１の角度間隔はθ３であり、約１３１度である。（θ１≠θ２，θ２≠θ３，θ３≠θ１，θ１＋θ２＋θ３＝２π）更に、前記取付孔部２２から前記脚部２５の後端までの中心軸線Ｘｂ方向の距離Ｌ１は、前記コードブッシュ２３の前記取付孔部２２からの突出部分の長さＬ２よりも長い。また、前記脚部２５の突出寸法Ｌ３は、前記電源コード１５の太さＬ４よりも長い。 The exhaust port portion 14 has a circular exhaust port 24 and a plurality of (three in this embodiment) leg portions 25 as ground contact portions provided so as to surround the exhaust port 24 . Note that these leg portions 25 may be one short cylindrical leg portion. These legs 25 are provided coaxially with the center axis Xb as a whole. Engagement projections 26 are provided on the outer peripheral surfaces of these leg portions 25 so as to protrude in a direction perpendicular to the central axis Xb. The engaging projections 26 are provided at different angular intervals. The angular interval between the first engaging projection 261 and the second engaging projection 262 is θ1 , which is approximately 127 degrees . The angular interval between the second engaging projection 262 and the third engaging projection 263 is θ2 , which is about 102 degrees . The angular interval between the third engaging projection 263 and the first engaging projection 261 is θ3 , which is approximately 131 degrees . (θ1≠θ2, θ2≠θ3, θ3≠θ1, θ1+θ2+θ3=2π) Further, the distance L1 from the mounting hole 22 to the rear end of the leg 25 in the direction of the central axis Xb is It is longer than the length L2 of the projecting portion from the hole 22 . Further, the projection dimension L3 of the leg portion 25 is longer than the thickness L4 of the power cord 15. As shown in FIG.

前記電動送風機３０について詳述する。この電動送風機３０は、電動機３１と遠心ファン３２とを有して構成される。前記電動機３１は、固定子３３と回転子３４と整流子３５とブラシ３６とを有する。なお、前記電動機３１の固定子３３には、回転軸の中心軸線Ｘｍからの距離が長い部分Ａと、中心軸線Ｘｍからの距離が短い部分Ｂが存在する。例えば、前記固定子３３の中心軸線Ｘｍからの寸法は、図６においてＷ１であり、図７においてＷ２である。そして、Ｗ１はＷ２よりも短い。一方、前記遠心ファン３２は、中心軸線Ｘｍと直交するあらゆる方向から見て半径Ｒが同じである。そして、前記電動送風機３０は、その遠心ファン３２が前記外殻体１３のファン収容部１６の内側に配置される。また、前記電動送風機３０は、その電動機３１が前記外殻体１３の段差部１８から電動機収容部１７にかけての内側に配置される。なお、前記電動送風機３０は、前記部分Ｂが上下で且つ前記部分Ａが左右となるように、前記外殻体１３内に収容される。従って、前記電動機３１の固定子３３の下部となる前記部分Ｂから前記段差部１８の下部１８Ｄの内面までの距離は、前記固定子３３の右部又は左部となる前記部分Ａから前記段差部１８の右部又は左部の内面までの距離よりも長い。即ち、前記段差部１８の下部１８Ｄの内側には空間的な余裕がある。このため、前記段差部１８の下部１８Ｄの脚部２１に前記取付孔部２２が設けられ、この取付孔部２２に前記電源コード１５のコードブッシュ２３が固定される。このように、前記段差部１８の下部１８Ｄから前記電源コード１５を引き出すことで、前記掃除機本体１０の内部における配線が前記電動送風機３０と干渉しないので、製造が容易である。また、前記外殻体１３を小型化することができる。更に、前記掃除機本体１０の内部における配線に無理がないので、前記掃除機本体１０内で断線が生じる虞を減ずることができる。 The electric blower 30 will be described in detail. The electric blower 30 includes an electric motor 31 and a centrifugal fan 32 . The electric motor 31 has a stator 33 , a rotor 34 , a commutator 35 and brushes 36 . The stator 33 of the electric motor 31 has a portion A with a long distance from the central axis Xm of the rotating shaft and a portion B with a short distance from the central axis Xm. For example, the dimension of the stator 33 from the central axis Xm is W1 in FIG. 6 and W2 in FIG. And W1 is shorter than W2. On the other hand, the centrifugal fan 32 has the same radius R when viewed from all directions perpendicular to the central axis Xm. The centrifugal fan 32 of the electric blower 30 is arranged inside the fan accommodating portion 16 of the outer shell 13 . The motor 31 of the electric blower 30 is arranged inside from the stepped portion 18 of the outer shell 13 to the motor accommodating portion 17 . The electric blower 30 is accommodated in the outer shell 13 so that the portion B is arranged vertically and the portion A is arranged horizontally. Therefore, the distance from the portion B, which is the lower portion of the stator 33 of the electric motor 31, to the inner surface of the lower portion 18D of the step portion 18 is the same as the portion A, which is the right or left portion of the stator 33, to the step portion longer than the distance to the inner surface of the right or left part of 18. That is, there is a spatial margin inside the lower portion 18D of the stepped portion 18. As shown in FIG. For this reason, the mounting hole portion 22 is provided in the leg portion 21 of the lower portion 18D of the stepped portion 18, and the cord bush 23 of the power cord 15 is fixed to the mounting hole portion 22. As shown in FIG. By pulling out the power cord 15 from the lower portion 18D of the stepped portion 18 in this manner, the wiring inside the cleaner main body 10 does not interfere with the electric blower 30, which facilitates manufacturing. Also, the size of the outer shell 13 can be reduced. In addition, since the wiring inside the cleaner body 10 is easy, the risk of disconnection in the cleaner body 10 can be reduced.

前記集塵容器４０は、前述したように、前記掃除機本体１０の受部１９に対し着脱可能に取り付けられる。そして、前記集塵容器４０は、容器本体４１と、この容器本体４１に接続される導入路４２と、前記容器本体４１内に収容される図示しないフィルタ体とを有する。なお、前記導入路４２の下部には、脚部４３が設けられる。そして、前記電気掃除機２の下部が下方となるように、床面Ｆ等に置いた際に、前記脚部４３と脚部２１とが前記床面Ｆに接する。この際、前記排気口部１４から床面Ｆまでの距離Ｌ５は、前記電源コード１５の太さＬ４よりも長い。即ち、前記電気掃除機２の下部が下方となるように、床面Ｆ等に置く際に、前記電源コード１５が邪魔になることはない。 The dust container 40 is detachably attached to the receiving portion 19 of the cleaner body 10 as described above. The dust collection container 40 has a container body 41 , an introduction path 42 connected to the container body 41 , and a filter body (not shown) accommodated in the container body 41 . A leg portion 43 is provided below the introduction path 42 . When the electric vacuum cleaner 2 is placed on the floor surface F or the like so that the lower portion of the electric vacuum cleaner 2 faces downward, the leg portions 43 and 21 are in contact with the floor surface F. At this time, the distance L5 from the exhaust port portion 14 to the floor surface F is longer than the thickness L4 of the power cord 15 . That is, the power cord 15 does not become an obstacle when the vacuum cleaner 2 is placed on the floor surface F or the like so that the lower portion of the vacuum cleaner 2 faces downward.

前記アダプタ５０は、前記排気口部１４に対し着脱可能に取り付けられる。そして、前記アダプタ５０は、流通面積が相対的に大きい入口部としての取付部５１と、流通面積が相対的に小さい出口部としての受筒部５２と、ロックボタン５３とを有する。前記取付部５１の第一中心軸線Ｘ１は、前記アダプタ５０を前記排気口部１４に取り付けた際に、前記外殻体１３の中心軸線Ｘｂと同軸となる。一方、前記受筒部５２の第二中心軸線Ｘ２は、前記第一中心軸線Ｘ１に対し偏心している。なお、第一中心軸線Ｘ１と第二中心軸線Ｘ２は平行である。前記取付部５１の内周面には、複数の係合凹部５４が設けられる。これらの係合凹部５４は、前記排気口部１４の係合凸部２６に対応して設けられる。即ち、前記各係合凹部５４は、異なる角度間隔で設けられる。例えば、第一係合凹部５４１と第二係合凹部５４２の角度間隔はθ１であり、約１２７度である。第二係合凹部５４２と第三係合凹部５４３の角度間隔はθ２であり、約１０２度である。第三係合凹部５４３と第一係合凹部５４１の角度間隔はθ３であり、約１３１度である。従って、前記第一係合凸部２６１が第一係合凹部５４１に、第二係合凸部２６２が第二係合凹部５４２に、第三係合凸部２６３が第三係合凹部５４３係合した状態でのみ、前記アダプタ５０が前記排気口部１４に取り付けられる。この結合状態において、前記受筒部５２の第二中心軸線Ｘ２は、前記取付部５１の第一中心軸線Ｘ１及び前記外殻体１３の中心軸線Ｘｂに対し、前記把持部１２側である上側に偏る。即ち、前記受筒部５２の第二中心軸線Ｘ２は、前記取付部５１の第一中心軸線Ｘ１及び前記外殻体１３の中心軸線Ｘｂに対し、前記電源コード１５が設けられた下側の反対側である上側に偏る。なお、図示しないが、前記各係合凹部５４はＬ字状の溝である。従って、前記アダプタ５０は、前記排気口部１４に対しバヨネット結合される。 The adapter 50 is detachably attached to the exhaust port portion 14 . The adapter 50 has a mounting portion 51 as an inlet portion with a relatively large flow area, a receiving tube portion 52 as an outlet portion with a relatively small flow area, and a lock button 53 . The first central axis X1 of the attachment portion 51 is coaxial with the central axis Xb of the outer shell 13 when the adapter 50 is attached to the exhaust port portion 14 . On the other hand, the second central axis X2 of the receiving tube portion 52 is eccentric with respect to the first central axis X1. Note that the first central axis X1 and the second central axis X2 are parallel. A plurality of engaging recesses 54 are provided on the inner peripheral surface of the mounting portion 51 . These engaging concave portions 54 are provided corresponding to the engaging convex portions 26 of the exhaust port portion 14 . That is, the respective engaging recesses 54 are provided at different angular intervals. For example, the angular interval between the first engagement recess 541 and the second engagement recess 542 is θ1, which is approximately 127 degrees. The angular interval between the second engaging recess 542 and the third engaging recess 543 is θ2, which is approximately 102 degrees. The angular interval between the third engaging recess 543 and the first engaging recess 541 is θ3, which is approximately 131 degrees. Therefore, the first engaging protrusion 261 engages the first engaging recess 541, the second engaging protrusion 262 engages the second engaging recess 542, and the third engaging protrusion 263 engages the third engaging recess 543. The adapter 50 is attached to the exhaust port portion 14 only in the mated state. In this coupled state, the second central axis X2 of the receiving tube portion 52 is positioned above the holding portion 12 side with respect to the first central axis X1 of the mounting portion 51 and the central axis Xb of the outer shell 13. biased. That is, the second central axis X2 of the receiving tube portion 52 is opposite to the first central axis X1 of the mounting portion 51 and the central axis Xb of the outer shell 13 on the lower side where the power cord 15 is provided. Deviate to the upper side, which is the side. Although not shown, each engaging recess 54 is an L-shaped groove. Therefore, the adapter 50 is bayonet-coupled to the exhaust port portion 14 .

前記アタッチメント６０は、前記受筒部５２に対し着脱可能に接続される。詳述すると、前記アタッチメント６０には、図示しない係合凹部が設けられ、この係合凹部に対し前記ロックボタン５３に設けられた係合爪５５が係合することで、前記アタッチメント６０が前記受筒部５２に接続される。なお、前記アタッチメント６０は、図８に示すような、全体が筒状の延長パイプ６１や、図９に示すような、ホース状の部分を有する延長ホース６２が使用可能である。 The attachment 60 is detachably connected to the receiving tube portion 52 . More specifically, the attachment 60 is provided with an engagement recess (not shown), and the engagement claw 55 provided on the lock button 53 is engaged with the engagement recess, whereby the attachment 60 is engaged with the receiving part. It is connected to the cylindrical portion 52 . As the attachment 60, an extension pipe 61 having a cylindrical shape as a whole as shown in FIG. 8 or an extension hose 62 having a hose-like portion as shown in FIG. 9 can be used.

次に、本実施形態の作用について説明する。まず、前記電気掃除機システム１の電気掃除機２のみを使用する場合、使用者は予め前記掃除機本体１０の受部１９に前記集塵容器４０を取り付けておく。そして、前記電源コード１５を図示しない交流電源に接続し、前記把持部１２を把持して前記電動送風機３０を作動させることで、吸引掃除を行う。なお、吸引掃除は、前記導入路４２から直接塵埃を吸引するように行ってもよく、また、前記導入路４２に図示しない吸引掃除用アタッチメントを装着した状態で行ってもよい。そして、前記導入路４２から吸引された気流に含まれる塵埃は、前記集塵容器４０内で気流から分離されてこの集塵容器４０内に貯められる。塵埃が分離された気流は、前記電動送風機３０を経て前記排気口２４から前記電気掃除機２の外部に排出される。そして、吸引掃除を行う際、使用者は前記電気掃除機２の上部に設けられた前記把持部１２を把持するので、前記電気掃除機２の下部に設けられた前記電源コード１５が邪魔になることがない。 Next, the operation of this embodiment will be described. First, when only the vacuum cleaner 2 of the vacuum cleaner system 1 is used, the user attaches the dust collection container 40 to the receiving portion 19 of the vacuum cleaner main body 10 in advance. Then, the power cord 15 is connected to an AC power supply (not shown), and the electric blower 30 is operated by gripping the grip portion 12 to perform suction cleaning. The suction cleaning may be performed by directly sucking the dust from the introduction path 42, or may be performed with a suction cleaning attachment (not shown) attached to the introduction path 42. FIG. Dust contained in the airflow sucked from the introduction path 42 is separated from the airflow in the dust collection container 40 and collected in the dust collection container 40 . The airflow from which the dust has been separated is discharged to the outside of the vacuum cleaner 2 through the air outlet 24 through the electric blower 30 . When performing suction cleaning, the user grips the grip part 12 provided at the top of the vacuum cleaner 2, so the power cord 15 provided at the bottom of the vacuum cleaner 2 becomes an obstacle. never.

不使用時に、又は一時的に吸引掃除を停止して前記電気掃除機２を置く場合、幾つかの置き方がある。代表的な例として、図４に示すような、前記掃除機本体１０の脚部２１と前記集塵容器４０の脚部４３とが床面Ｆ等に接する置き方と、図５に示すような、前記電気掃除機２の排気口部１４の脚部２５が床面Ｆに接する置き方がある。前者の置き方では、前述した通り、前記排気口部１４から床面Ｆまでの距離Ｌ５が前記電源コード１５の太さＬ４よりも大きいので、前記電源コード１５が邪魔になることがない。また、前記電源コード１５が前記中心軸線Ｘｂと平行に引き出されることで、重力による僅かな屈曲があったとしても、前記コードブッシュ２３部分で前記電源コード１５が床面Ｆに当たって急激に屈曲することがない。このため、前記電源コード１５に大きなストレスが加わらない。後者の置き方では、前述した通り、前記取付孔部２２から前記脚部２５後端までの距離Ｌ１が、前記コードブッシュ２３の突出部分の長さＬ２よりも長いので、前記電源コード１５が床面Ｆに当たって屈曲しても、前記コードブッシュ２３部分が急激に屈曲することがない。このため、前記電源コード１５に大きなストレスが加わらない。なお、前記電源コード１５が前記排気口部１４の下方に入り込むことも起こり得る。しかしながら、前述した通り、前記脚部２５の突出寸法Ｌ３が前記電源コード１５の太さＬ４よりも長いので、この電源コード１５が前記排気口部１４と床面Ｆとで挟まれる虞を減ずることができる。即ち、前記電源コード１５が前記排気口部１４の下方に入り込んだとしても、前記電源コード１５が前記脚部２５同士の間の切欠部を通ることになる。特に、図１０に示すように、前記排気口部１４の下部に、前記脚部２５同士の間の切欠部が位置するので、前記電源コード１５が、その近くにある前記脚部２５同士の間の切欠部を通り易い。このように、前記電気掃除機２を置く際に、前記電源コード１５が破損しにくいようにすることができる。 There are several ways to place the vacuum cleaner 2 when not in use or when temporarily stopping suction cleaning. As a representative example, a method of placing the cleaner main body 10 and the dust container 40 in contact with the floor surface F or the like as shown in FIG. , the leg portion 25 of the exhaust port portion 14 of the electric vacuum cleaner 2 is placed in contact with the floor surface F. In the former arrangement, as described above, the distance L5 from the exhaust port 14 to the floor surface F is greater than the thickness L4 of the power cord 15, so the power cord 15 does not become an obstacle. Further, since the power cord 15 is pulled out in parallel with the central axis Xb, even if the power cord 15 is slightly bent due to gravity, the power cord 15 hits the floor surface F at the cord bush 23 and is sharply bent. There is no Therefore, the power cord 15 is not subjected to a large stress. In the latter placement, as described above, the distance L1 from the mounting hole 22 to the rear end of the leg 25 is longer than the length L2 of the protruding portion of the cord bush 23, so that the power cord 15 is placed on the floor. Even if it hits the surface F and bends, the cord bush 23 portion does not bend sharply. Therefore, the power cord 15 is not subjected to a large stress. It should be noted that the power cord 15 may enter below the exhaust port portion 14 . However, as described above, since the projection dimension L3 of the leg portion 25 is longer than the thickness L4 of the power cord 15, the risk of the power cord 15 being caught between the exhaust port portion 14 and the floor surface F can be reduced. can be done. That is, even if the power cord 15 enters below the exhaust port 14, the power cord 15 passes through the notch between the legs 25. As shown in FIG. In particular, as shown in FIG. 10, a cutout portion between the legs 25 is located at the lower portion of the exhaust port 14, so that the power cord 15 can be pulled out between the adjacent legs 25. It is easy to pass through the notch of In this way, the power cord 15 can be prevented from being damaged when the vacuum cleaner 2 is placed.

次に、前記電気掃除機システム１の電気掃除機２の排気口部１４に前記アダプタ５０及びアタッチメント６０を取り付けて使用する場合について説明する。なお、前述した通り、前記アダプタ５０は、前記排気口部１４に対しバヨネット結合される。そして、前述した通り、前記第一係合凸部２６１が第一係合凹部５４１に、第二係合凸部２６２が第二係合凹部５４２に、第三係合凸部２６３が第三係合凹部５４３係合した状態でのみ、前記アダプタ５０が前記排気口部１４に取り付けられる。この際、前記アダプタ５０は、その受筒部５２の中心軸線Ｘ２が前記外殻体１３の中心軸線Ｘｂに対し前記把持部１２側である上方に偏った状態でしか取り付けられない。換言すると、前記アダプタ５０は、その受筒部５２の中心軸線Ｘ２が前記外殻体１３の中心軸線Ｘｂに対し、反電源コード１５側である上側に偏った状態でしか取り付けられない。 Next, a case where the adapter 50 and the attachment 60 are attached to the exhaust port portion 14 of the electric vacuum cleaner 2 of the electric vacuum cleaner system 1 and used will be described. In addition, as described above, the adapter 50 is bayonet-coupled to the exhaust port portion 14 . As described above, the first engaging protrusion 261 is engaged with the first engaging recess 541, the second engaging protrusion 262 is engaged with the second engaging recess 542, and the third engaging protrusion 263 is engaged with the third engaging recess. The adapter 50 is attached to the exhaust port portion 14 only in a state where the joint recess 543 is engaged. At this time, the adapter 50 can be attached only in a state in which the central axis X2 of the receiving tube portion 52 is biased upward, ie, the grip portion 12 side, with respect to the central axis Xb of the outer shell 13 . In other words, the adapter 50 can only be attached in such a state that the central axis X2 of the receptacle portion 52 is biased toward the upper side, which is opposite to the power cord 15 side, with respect to the central axis Xb of the outer shell 13 .

前記アダプタ５０の受筒部５２にパイプ状の前記延長パイプ６１を接続して使用する場合、使用者は、吸引掃除を行う場合とは前後逆に前記把持部１２を把持する。即ち、使用者は、前記排気口部１４が前となるように把持する。この状態で前記電動送風機３０を作動させると、前記導入路４２から吸引された気流は、前記電動送風機３０を経て前記排気口２４から前記電気掃除機２の外部に排出される。そして、前記電気掃除機２の外部に排出された気流は、前記アダプタ５０の取付部５１から受筒部５２を経て前記延長パイプ６１から噴出する。この噴出気流を用いて、使用者は地面等に散乱している落ち葉等の塵埃を吹き飛ばすことができる。 When the pipe-shaped extension pipe 61 is connected to the receiving tube portion 52 of the adapter 50 and used, the user grips the grip portion 12 in the front-to-rear reversed manner in the case of suction cleaning. That is, the user holds the device so that the exhaust port portion 14 faces forward. When the electric blower 30 is operated in this state, the airflow sucked from the introduction passage 42 is discharged to the outside of the electric vacuum cleaner 2 through the electric blower 30 and the exhaust port 24 . The airflow discharged to the outside of the electric vacuum cleaner 2 is ejected from the extension pipe 61 through the mounting portion 51 of the adapter 50 and the receiving tube portion 52 . A user can blow away dust such as fallen leaves scattered on the ground or the like by using this jet airflow.

この際、噴出気流により、使用者の手に反動が生じる。しかしながら、前記アダプタ５０の受筒部５２の中心軸線Ｘ２が前記外殻体１３の中心軸線Ｘｂよりも前記把持部１２側、即ち使用者の手の側に偏っていることで、噴出気流の反動を使用者の手の近くで受けることになる。このため、噴出気流の反動を抑えて、安定して前記電気掃除機システム１を操作することができる。なお、前記受筒部５２に前記延長ホース６２を接続する場合、一方の手で前記把持部１２を、他方の手で前記延長ホース６２の先端を把持することになる。この場合、噴出気流による反動は、他方の手が受けることになる。また、前記受筒部５２に前記延長ホース６２を接続する場合、使用者は前記把持部１２をどのように把持してもよい。 At this time, the jetting air current causes the user's hand to recoil. However, since the central axis X2 of the receiving tube portion 52 of the adapter 50 is biased toward the grip portion 12 side, i.e., the user's hand side, with respect to the central axis Xb of the outer shell 13, the reaction of the ejected airflow occurs. is received near the user's hand. Therefore, the vacuum cleaner system 1 can be stably operated by suppressing the recoil of the ejected airflow. When the extension hose 62 is connected to the receiving tube portion 52, the holding portion 12 is gripped with one hand and the tip of the extension hose 62 is gripped with the other hand. In this case, the other hand receives the recoil caused by the ejected airflow. Further, when connecting the extension hose 62 to the receiving tube portion 52, the user may grip the grip portion 12 in any manner.

また、前述した通り、前記アダプタ５０の受筒部５２の中心軸線Ｘ２が前記外殻体１３の中心軸線Ｘｂよりも反電源コード１５側に偏っていると共に、この電源コード１５が前記アダプタ５０よりも下方に位置するので、前記電源コード１５が前記アダプタ５０やアタッチメント６０に絡んでしまうことがない。従って、噴出気流を用いる掃除を良好に行うことができる。 Further, as described above, the central axis X2 of the receptacle portion 52 of the adapter 50 is biased toward the side opposite to the power cord 15 with respect to the central axis Xb of the outer shell 13, and the power cord 15 extends from the adapter 50. , so that the power cord 15 is not entangled with the adapter 50 or the attachment 60.例文帳に追加Therefore, cleaning using the jet airflow can be performed well.

不使用時に、又は一時的に噴出気流を用いる掃除を停止して、前記アダプタ５０やアタッチメント６０を取り付けたまま前記電気掃除機システム１を置く場合、図９に示すように、前記掃除機本体１０の脚部２１と前記集塵容器４０の脚部４３とが床面Ｆ等に接するように置く。なお、前記延長パイプ６１が前記受筒部５２に接続された状態では、前記延長パイプ６１が床面Ｆ等に接し、前記脚部２１が床面Ｆに接しない。従って、この場合、前記電気掃除機システム１を安定して置くことができないので、前記延長パイプ６１、又は前記アダプタ５０と延長パイプ６１の両方を前記排気口部１４から取り外す。一方、前記延長ホース６２が前記受筒部５２に接続されている場合、図９に示すように、ホース状の部分６２Ｈが屈曲するので、前記延長ホース６２を取り付けた状態のまま前記電気掃除機システム１を床面Ｆ等に置くことができる。そして、前記アダプタ５０の受筒部５２の中心軸線Ｘ２が前記外殻体１３の中心軸線Ｘｂよりも反上方に偏っているので、前記延長ホース６２の接続筒部６２Ｔが床面Ｆ等に接するのを防止することができる。これによって、前記アダプタ５０及び延長ホース６２を接続したまま、前記電気掃除機システム１を床面Ｆ等に安定して置くことができる。 When the vacuum cleaner system 1 is placed while the adapter 50 and the attachment 60 are attached when not in use or when cleaning using the jet air is temporarily stopped, the cleaner body 10 is placed as shown in FIG. and the leg portion 43 of the dust collecting container 40 are placed in contact with the floor surface F or the like. When the extension pipe 61 is connected to the receiving tube portion 52, the extension pipe 61 is in contact with the floor surface F and the like, and the leg portion 21 is not in contact with the floor surface F. Therefore, in this case, since the electric vacuum cleaner system 1 cannot be placed stably, the extension pipe 61 or both the adapter 50 and the extension pipe 61 are removed from the exhaust port portion 14 . On the other hand, when the extension hose 62 is connected to the receiving tube portion 52, the hose-shaped portion 62H is bent as shown in FIG. The system 1 can be placed on the floor F or the like. Since the central axis X2 of the receiving tube portion 52 of the adapter 50 is biased upward from the central axis Xb of the outer shell 13, the connecting tube portion 62T of the extension hose 62 contacts the floor surface F or the like. can be prevented. As a result, the vacuum cleaner system 1 can be stably placed on the floor surface F or the like while the adapter 50 and the extension hose 62 are connected.

以上のように本発明の電気掃除機システム１は、把持部１２及び排気口部１４を有する電気掃除機２と、流通面積が相対的に大きい入口部としての取付部５１と流通面積が相対的に小さい出口部としての受筒部５２とを有する排気利用アダプタ５０と、排気アタッチメント６０と、を有する電気掃除機システム１において、前記アダプタ５０の取付部５１が前記電気掃除機２の排気口部１４に接続され、前記アダプタ５０の受筒部５２に前記アタッチメント６０が接続されると共に、前記アダプタ５０が前記排気口部１４に取り付けられた状態で、前記取付部５１の第一中心Ｘ１に対し前記受筒部５２の第二中心Ｘ２が前記把持部１２側に偏心して設けられることで、排気の噴出位置を前記把持部１２の近くにすることができるので、噴出気流を利用する際に、この噴出気流による反動を抑えて安定して操作することができるものである。 As described above, the vacuum cleaner system 1 of the present invention includes the vacuum cleaner 2 having the grip portion 12 and the exhaust port portion 14, the attachment portion 51 as the inlet portion having a relatively large flow area, and the flow area being relatively large. In a vacuum cleaner system 1 having an exhaust utilization adapter 50 having a receiving tube portion 52 as a small outlet portion and an exhaust attachment 60, the mounting portion 51 of the adapter 50 is attached to the exhaust port portion of the vacuum cleaner 2. 14, the attachment 60 is connected to the receiving cylinder portion 52 of the adapter 50, and the adapter 50 is attached to the exhaust port portion 14. By eccentrically providing the second center X2 of the receiving tube portion 52 toward the grip portion 12, the ejection position of the exhaust gas can be set near the grip portion 12. Therefore, when using the ejected airflow, It is possible to stably operate by suppressing the recoil caused by this ejected air flow.

また、本発明の電気掃除機システム１は、前記電気掃除機２の排気口部１２に、結合のための係合凸部２６１，２６２，２６３が複数形成され、前記アダプタ５０の取付部５１に、結合のための係合凹部５４１，５４２，５４３が複数形成されると共に、これら係合凹部５４１，５４２，５４３と係合凸部２６１，２６２，２６３とが不等間隔で設けられることで、前記受筒部５２が確実に前記把持部１２側に偏った状態で前記アダプタ５０を前記排気口部１４に取り付けることができるものである。 Further, in the vacuum cleaner system 1 of the present invention, a plurality of engaging protrusions 261 , 262 , 263 for coupling are formed in the exhaust port portion 12 of the vacuum cleaner 2 , and the mounting portion 51 of the adapter 50 has , By forming a plurality of engagement recesses 541, 542, 543 for coupling and providing these engagement recesses 541, 542, 543 and engagement protrusions 261, 262, 263 at uneven intervals, The adapter 50 can be attached to the exhaust port portion 14 in a state in which the receiving tube portion 52 is reliably biased toward the grip portion 12 side.

更に、本発明の電気掃除機システム１は、前記電気掃除機２が電源コード１５を有すると共に、前記アダプタ５０が前記排気口部１４に取り付けられた状態で、前記受筒部５２が反電源コード１５側に偏って設けられることで、前記電源コード１５が前記アタッチメント６０と絡みにくく、容易に操作することができるものである。 Further, in the vacuum cleaner system 1 of the present invention, the vacuum cleaner 2 has the power cord 15 and the adapter 50 is attached to the exhaust port portion 14, and the receptacle portion 52 is connected to the opposite side of the power cord. By being biased toward the 15 side, the power cord 15 is less likely to get entangled with the attachment 60, and can be easily operated.

なお、本発明は以上の実施形態に限定されるものではなく、発明の要旨の範囲内で種々の変形実施が可能である。例えば、上記実施形態では、排気口部に係合凸部を、アダプタに係合凹部を設けたが、排気口部に係合凹部を、アダプタに係合凸部を設けてもよい。また、上記実施形態では、第一係合凸部と第二係合凸部と第三係合凸部の角度間隔を全て異ならせたが、要は排気口部とアダプタの位置関係が定まればよいので、第一係合凸部と第二係合凸部と第三係合凸部の角度間隔のうち、一つだけを異ならせるようにしてもよい。同様に、第一係合凹部と第二係合凹部と第三係合凹部の角度間隔を全て異ならせたが、第一係合凹部と第二係合凹部と第三係合凹部の角度間隔のうち、一つだけを異ならせるようにしてもよい。更に、取付部の第一中心軸線に対する受筒部の第二中心軸線の偏心量は、任意に設定可能である。例えば、上記実施形態では、第一中心軸線Ｘ１に沿って見た受筒部が、取付部の輪郭内に位置するが、受筒部が取付部の輪郭外に位置するような位置関係としてもよい。更にまた、上記実施形態では、取付部の第一中心軸線と受筒部の第二中心軸線とが平行であるが、取付部に対し受筒部を傾斜させてもよい。 It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist of the invention. For example, in the above-described embodiment, the engaging protrusion is provided on the exhaust port and the engaging recess is provided on the adapter, but the engaging recess may be provided on the exhaust port and the engaging protrusion may be provided on the adapter. In the above embodiment, the angular intervals of the first engagement projection, the second engagement projection, and the third engagement projection are all different, but the point is that the positional relationship between the exhaust port and the adapter is determined. Therefore, only one of the angular intervals among the first engaging protrusion, the second engaging protrusion, and the third engaging protrusion may be different. Similarly, the angular intervals between the first engaging recess, the second engaging recess, and the third engaging recess are all different, but the angular intervals between the first engaging recess, the second engaging recess, and the third engaging recess Only one of them may be different. Furthermore, the amount of eccentricity of the second central axis of the receiving tube portion with respect to the first central axis of the mounting portion can be set arbitrarily.
