実施の形態１の電気掃除機１０は、図１、図２に示しているように電動送風機駆動用モータ（ブロワーモータとも言うが以下、単に「モータ」という）１、集塵室２、連結風路３、吸込口４、集塵室後壁５、連通穴６、接触面７、コードリール８を有する。Ｃは電気掃除機の外殻を形成する本体ケースで、背面が開口した前ケースＦＣと、この前ケースに着脱自在に結合され、結合時には前ケースの背面開口を閉塞する後ケースＢＣとから構成されている。
前記モータ１は、図２に示すように電気掃除機１０の後ケースＢＣ内部の上部に配置され、前方より空気を吸引し後方へ空気を排出する。 As shown in FIGS. 1 and 2, the electric vacuum cleaner 10 according to the first embodiment includes an electric blower driving motor (also referred to as a blower motor, hereinafter simply referred to as “motor”) 1, a dust collecting chamber 2, and a connected wind. It has a path 3, a suction port 4, a dust collection chamber rear wall 5, a communication hole 6, a contact surface 7, and a cord reel 8.

As shown in FIG. 2, the motor 1 is disposed in the upper part of the rear case BC of the vacuum cleaner 10 and sucks air from the front and discharges the air to the rear.

前記集塵室２は前ケースの内部に形成され、その内部には集塵フィルターとなる紙パック式フィルター（図示せず）が設置されている。なおこの集塵フィルターは前ケースＦＣを後ケースから外した状態で取り出せることができるようになっている。なお、使い捨てタイプの紙パック式フィルターではなく、前ケースＦＣに固定され、反復使用できるような集塵フィルターでも良く、さらに紙パック式フィルターと同時に使用する構成であっても良い。   The dust collection chamber 2 is formed inside the front case, and a paper pack filter (not shown) serving as a dust collection filter is installed inside the dust collection chamber 2. The dust collecting filter can be taken out with the front case FC removed from the rear case. Instead of a disposable paper pack filter, it may be a dust collection filter that is fixed to the front case FC and can be used repeatedly, and may be configured to be used simultaneously with the paper pack filter.

前記連結風路３はモータ１と集塵室２の間に配置され、集塵室２から排出した空気をモータ１に送る風路となっており、一般的には中空の円筒形状をしている。
吸込口４は集塵室２の上流に配置されるよう、前ケースＦＣの前面壁に形成され集塵室２に空気を取り込む入口となっている。また、この吸込口の上流には屈曲自在なホース等の吸い込み用具が着脱自在に接続される。 The connecting air passage 3 is disposed between the motor 1 and the dust collecting chamber 2 and serves as an air passage for sending the air discharged from the dust collecting chamber 2 to the motor 1, and generally has a hollow cylindrical shape. Yes.
The suction port 4 is formed on the front wall of the front case FC so as to be placed upstream of the dust collection chamber 2 and serves as an inlet for taking air into the dust collection chamber 2. A suction tool such as a bendable hose is detachably connected upstream of the suction port.

前記集塵室後壁５は集塵室２の後方壁である。
前記連通穴６は集塵室後壁５に設けられた円形の穴であり、連結風路３の前方（上流）端部と連通している。 The dust collection chamber rear wall 5 is a rear wall of the dust collection chamber 2.
The communication hole 6 is a circular hole provided in the dust collection chamber rear wall 5 and communicates with the front (upstream) end of the connection air passage 3.

コードリール８は電気掃除機１０の後ケースＢＣ内部の下部に配置され、電気掃除機１０のモータ１に電源を供給する電源コードがリールに巻かれて収納されている。なお、このコードリールはそのリールの回転中心軸が垂直（鉛直）であるため、水平面内で回転する構成になっている。 The contact surface 7 is a surface (downstream end portion) nearer to the air introduction port of the motor 1 in the connection air passage 3, and is in close contact with the peripheral portion of the air introduction port of the motor 1 to improve the airtightness of the connection air passage 3. Is maintained.
The cord reel 8 is disposed in the lower part of the rear case BC of the vacuum cleaner 10, and a power cord for supplying power to the motor 1 of the vacuum cleaner 10 is wound around the reel and stored. This cord reel is configured to rotate in a horizontal plane because the rotation center axis of the reel is vertical (vertical).

次に、電気掃除機１０の中を通る風の流れについて説明する。
モータ１の駆動により吸込口４から集塵室２の中に入った空気は、連通穴６から連結風路３を通ってモータ１に運ばれる。符号ＦＬの矢印は空気の流れを示す。 Next, the flow of wind passing through the vacuum cleaner 10 will be described.
The air that has entered the dust collection chamber 2 from the suction port 4 by driving the motor 1 is conveyed to the motor 1 from the communication hole 6 through the connection air passage 3. The arrow of the symbol FL indicates the air flow.

その後、モータ１の中の通路を通過した空気は、モータ１の後方から後ケースＢＣに形成された排気口を通り、電気掃除機１０の外へと排出される。つまり、図１、図２の電気掃除機１０は、前記連通穴６の中心軸線Ｘ１と前記モータ２の中心軸線Ｘ２は、水平方向では偏位（寸法のズレ）がゼロであるが、鉛直方向においては所定の偏位Ｙ１があり、前記連通穴６から前記モータ２の間は、前記中心線Ｘ１と中心線Ｘ２を直線的につなぐようにこれら二つの中心線に対して前記連結風路３の中心軸線Ｘ３を所定角度α１傾斜させているから、吸込口４から集塵室２に流入した空気が連通穴６から排出された直後においては上方向へなめらかに屈折し、風路損失が小さい。なお、前記所定角度α１は、３０度以下が望ましい。   Thereafter, the air that has passed through the passage in the motor 1 passes through an exhaust port formed in the rear case BC from the rear of the motor 1 and is discharged out of the electric vacuum cleaner 10. That is, in the vacuum cleaner 10 of FIGS. 1 and 2, the center axis X1 of the communication hole 6 and the center axis X2 of the motor 2 are zero in the horizontal direction (dimensional deviation), but the vertical direction , There is a predetermined displacement Y1, and between the communication hole 6 and the motor 2, the connecting air passage 3 is connected to the two center lines so as to linearly connect the center line X1 and the center line X2. Since the central axis line X3 is inclined at a predetermined angle α1, immediately after the air flowing into the dust collecting chamber 2 from the suction port 4 is discharged from the communication hole 6, it is smoothly refracted upward and the air path loss is small. . The predetermined angle α1 is preferably 30 degrees or less.

このように、モータ１の吸込み性能を十分に発揮する為には、排気風路である連結風路３をなめらか（排気流が流れる風路の途中で急激な屈折や絞りなどが無い形状）に形成することが望ましく、特にモータ１より上流での連結風路３の形状が、モータ１の吸込み性能への影響が大きいが、前記した実施の形態１では連通穴６から排出された直後において排気風は上方向へなめらかに屈折し、風路損失が小さい。   As described above, in order to sufficiently exhibit the suction performance of the motor 1, the connecting air passage 3 that is the exhaust air passage is smooth (a shape that does not have a sharp refraction or a restriction in the air passage through which the exhaust flow flows). In particular, the shape of the connecting air passage 3 upstream from the motor 1 has a great influence on the suction performance of the motor 1, but in the first embodiment, the exhaust gas is exhausted immediately after being discharged from the communication hole 6. The wind is smoothly refracted upward and the wind path loss is small.

In the following description, the same reference numerals are given to the same parts as those in the cleaner of the first embodiment, and the description may be omitted.

実施の形態２に係る電気掃除機１０は、モータ１、集塵室２、連結風路３、吸込口４、集塵室後壁５、連通穴６、接触面７、コードリール８を有する。
モータ１は電気掃除機１０の内部の後方右部に配置され、前方より空気を吸引し後方へ空気を排出する。 A vacuum cleaner 10 according to Embodiment 2 includes a motor 1, a dust collection chamber 2, a connection air passage 3, a suction port 4, a dust collection chamber rear wall 5, a communication hole 6, a contact surface 7, and a cord reel 8.
The motor 1 is arrange | positioned in the back right part inside the vacuum cleaner 10, sucks air from the front, and discharges air to the back.

この実施の形態２に係る電気掃除機は、電動送風機駆動用モータ１と、モータより上流に位置する集塵室２と、前記モータ１と前記集塵室２の間に位置する連結風路３とを備え、前記集塵室２は上流側に吸込口４、下流側に集塵室後壁５を備え、この集塵室後壁５には前記連結風路３と連通する連通穴６を形成し、この連通穴から前記モータ１の空気導入口間を前記連結風路で連結し、前記連通穴の中心軸線Ｘ１と前記モータの中心軸線Ｘ２は、鉛直方向では偏位はゼロであり、水平方向では所定の偏位Ｙ２があり、前記連通穴６から前記モータ１の間においては、前記中心線Ｘ１と中心線Ｘ２を直線的につなぐようにこれら二つの中心線に対して前記連結風路３の中心軸線Ｘ３を所定角度α２傾斜させている。なお、前記所定角度α２は、３０度以下が望ましい。 The vacuum cleaner according to the second embodiment includes an electric blower driving motor 1, a dust collection chamber 2 located upstream from the motor, and a connected air passage 3 located between the motor 1 and the dust collection chamber 2. The dust collection chamber 2 includes a suction port 4 on the upstream side and a dust collection chamber rear wall 5 on the downstream side. The dust collection chamber rear wall 5 has a communication hole 6 communicating with the connection air passage 3. Formed, and the air inlets of the motor 1 are connected by the connecting air passages from the communication holes, and the center axis X1 of the communication holes and the center axis X2 of the motor have zero deviation in the vertical direction, There is a predetermined deviation Y2 in the horizontal direction, and between the communication hole 6 and the motor 1, the connecting wind is connected to the two centerlines so as to linearly connect the centerline X1 and the centerline X2. The central axis X3 of the path 3 is inclined by a predetermined angle α2. The predetermined angle α2 is preferably 30 degrees or less.

実施の形態２において、電気掃除機１０の中を通る風の流れは、実施の形態１と同様なので説明はしないが、吸込口４から集塵室２に流入した空気が連通穴６から排出された直後においては横方向へなめらかに屈折し、風路損失が小さい。 In the second embodiment, the flow of wind passing through the vacuum cleaner 10 is the same as that in the first embodiment and will not be described. However, the air flowing into the dust collecting chamber 2 from the suction port 4 is discharged from the communication hole 6. Immediately after that, the light is smoothly refracted in the lateral direction and the air path loss is small.

前記２つの実施の態様で、所定角度α１とα２は同一でも良い。また偏位Ｙ１とＹ２が同一であっても良い。また水平と垂直以外の方向、例えばその中間の角度（例えば正面から見て４５度左上）に、連結風路３が傾斜しているものでも良いし、また水平と垂直の両方に傾斜しているものでも良い。 In the two embodiments, the predetermined angles α1 and α2 may be the same. Further, the deviations Y1 and Y2 may be the same. Further, the connecting air passage 3 may be inclined in a direction other than horizontal and vertical, for example, an intermediate angle (for example, 45 degrees upper left when viewed from the front), or in both horizontal and vertical directions. Things can be used.

実施の形態３．
図５は、本発明の実施の形態３に係る電気掃除機を上方向から見た図であり、図６は、本発明の実施の形態３に係る電気掃除機を横方向から見た図である。
以下の説明では前記実施の形態１の掃除機と同一部分には同一符号を付し、説明を省略する場合がある。 Embodiment 3 FIG.
FIG. 5 is a view of the electric vacuum cleaner according to the third embodiment of the present invention as viewed from above, and FIG. 6 is a view of the electric vacuum cleaner according to the third embodiment of the present invention as viewed from the lateral direction. is there.
In the following description, the same reference numerals are given to the same parts as those in the cleaner of the first embodiment, and the description may be omitted.

この実施の態様３に係る電気掃除機１０は、電動送風機駆動用モータ１と、モータより上流に位置する集塵室２と、前記モータ１と前記集塵室２の間に位置する連結風路３とを備え、前記集塵室２は上流側に吸込口４、下流側に集塵室後壁５を備え、この集塵室後壁には前記連結風路３と連通する連通穴６を形成し、この連通穴から前記モータ１の空気導入口間口に至る連結風路は、その中心軸線Ｘ３が前記連通穴６の中心軸線Ｘ１に対して所定角度β１以下に傾斜している。つまり、モータ１はその中心軸線が、垂直になっている集塵室後壁５に対し所定の角度β１をつけて配置することにより、モータ１の中心軸線が水平面においては連通穴６の中心軸線と一直線上に配置されて偏位が無く、一方垂直面においてはモータ１の中心軸線が連通穴６の中心軸線と所定の角度β１だけ傾斜している。 The vacuum cleaner 10 according to the third embodiment includes an electric blower driving motor 1, a dust collection chamber 2 located upstream of the motor, and a connected air passage located between the motor 1 and the dust collection chamber 2. The dust collection chamber 2 includes a suction port 4 on the upstream side and a dust collection chamber rear wall 5 on the downstream side. The dust collection chamber rear wall has a communication hole 6 communicating with the connection air passage 3. The connection air passage formed and extending from the communication hole to the air inlet opening of the motor 1 has a center axis X3 inclined at a predetermined angle β1 or less with respect to the center axis X1 of the communication hole 6. That is, the motor 1 is arranged with the central axis of the motor 1 arranged at a predetermined angle β1 with respect to the vertical dust collection chamber rear wall 5, so that the central axis of the motor 1 is the central axis of the communication hole 6 in the horizontal plane. In the vertical plane, the central axis of the motor 1 is inclined with respect to the central axis of the communication hole 6 by a predetermined angle β1.

実施の形態３に係る電気掃除機１０の中を通る風の流れは、実施の形態１と同様なので詳しく説明はしないが、連通穴６が吸込口４と水平面では一直線に配置され、垂直面では所定の角度角度β１だけ傾斜している。さらにモータ１の中心軸が連結風路３の中心軸と一直線上に配置されている為、吸込口４から流入した空気が連通穴６を出た直後には水平面では全く屈曲せず、垂直面では上（鉛直）方向へなめらかに屈折するから、風路損失が小さい。 The flow of the wind passing through the vacuum cleaner 10 according to the third embodiment is the same as that of the first embodiment, and thus will not be described in detail. However, the communication hole 6 is arranged in a straight line between the suction port 4 and the horizontal plane, It is inclined by a predetermined angle angle β1. Further, since the central axis of the motor 1 is arranged in line with the central axis of the connection air passage 3, the air flowing in from the suction port 4 does not bend at the horizontal plane immediately after it exits the communication hole 6, and the vertical plane Then, since the light is smoothly refracted in the upward (vertical) direction, the air path loss is small.

また、電気掃除機１０は組立ての時にモータ１を後ケースＢＣの中に上方から入れるのが一般的となっている為、モータ１を所定角度β１つけて配置しているこの構成では、接触面７も角度がついているので、モータ１の後ケースＢＣへの挿入作業も容易となる。 Further, since the electric vacuum cleaner 10 is generally put into the rear case BC from above when assembled, the motor 1 is arranged with a predetermined angle β1 in this configuration. Since 7 is also angled, the work of inserting the motor 1 into the rear case BC becomes easy.

In the following description, the same reference numerals are given to the same parts as those in the cleaner of the first embodiment, and the description may be omitted.
In the vacuum cleaner 10 according to the fifth embodiment, the front case FC of the main body case C that forms the dust collection chamber 2 has a double structure, and the outside of the plastic molded product whose surface is painted or decorated. A case (not shown) and a dust collecting case 13 which is integrally molded with plastic and whose entire upper surface is opened are configured. A circular suction port 4 is formed in the dust collection case 13 in the front, and a circular communication hole 6 that is entirely covered with a lattice 14 is formed in the rear surface (rear wall surface) corresponding thereto.

集塵ケース１３の背面壁となる集塵室後壁５の後側表面には、図１０に示すように全体が二重壁構造になった中空筒状の連結風路３が一体に形成されている。この連結風路全体は斜め上方に全体が傾斜しており、その末端部の口縁部が電動送風機駆動用モータ１の込口側に接触する接触面７となる。なお、実際には、電動送風機駆動用モータ１の吸込口周縁部にはこれを囲むようにゴムなどの弾力性に富む材料で形成されたシール部材が事前に取り付けられ、そのシール材が前記接触面７の全周に亘って接触することで集塵室２からモータ１までに機密性が維持される。 On the rear surface of the dust collection chamber rear wall 5 which is the back wall of the dust collection case 13, a hollow cylindrical connecting air passage 3 having a double wall structure as a whole is integrally formed as shown in FIG. ing. The entire connecting air passage is inclined obliquely upward, and the edge portion of the end portion thereof becomes a contact surface 7 that comes into contact with the inlet side of the motor 1 for driving the electric blower. Actually, a seal member made of a material having high elasticity such as rubber is attached in advance to the peripheral portion of the suction port of the motor 1 for driving the electric blower so that the seal member is in contact with the contact material. By contacting the entire circumference of the surface 7, confidentiality is maintained from the dust collection chamber 2 to the motor 1.

実施の形態５に係る電気掃除機１０の中を通る風の流れは、実施の形態１と同様なので詳しく説明はしないが、吸込口４から流入した空気が集塵ケース１３の内部空間として形成される集塵室２の中を真直ぐ後方に進み、連通穴６から排出された直後は、垂直面では上（鉛直）方向に屈曲し、また水平面では横に屈折しないから、風路損失が小さい。 The flow of wind passing through the vacuum cleaner 10 according to the fifth embodiment is the same as that of the first embodiment and will not be described in detail. However, the air flowing in from the suction port 4 is formed as the internal space of the dust collecting case 13. Immediately after passing through the dust collecting chamber 2 and being discharged from the communication hole 6, the vertical plane is bent upward (vertical), and the horizontal plane is not refracted laterally, so that the air path loss is small.

発明に係る電気掃除機によれば、電動送風機駆動用モータに至る前の連結風路での風路損失を少なくすることができるから、広く一般の電気掃除機に広く利用できる。 According to the vacuum cleaner which concerns on invention, since the air path loss in the connection air path before reaching the motor for driving an electric blower can be reduced, it can be widely used for general vacuum cleaners.
