以下、本発明を実施するための形態（以下「実施形態」という）について、適宜図面を参照しながら詳細に説明する。 Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as “embodiments”) will be described in detail with reference to the drawings as appropriate.

図１は、本実施形態の電気掃除機の斜視図である。 FIG. 1 is a perspective view of the vacuum cleaner of the present embodiment.

図２は、本実施形態の電気掃除機の分解図である。 FIG. 2 is an exploded view of the vacuum cleaner of the present embodiment.

図２に示すように、電気掃除機１００は、掃除機本体１、ダストケース２（集塵装置）、蓄電池３（蓄電装置）を備えて構成されている。 As shown in FIG. 2, the vacuum cleaner 100 includes a vacuum cleaner main body 1, a dust case 2 (dust collector), and a storage battery 3 (storage device).

掃除機本体１は、本体部１０、モータケース部１１、ハンドル部１２を備えて構成されている。 The vacuum cleaner main body 1 is configured to include a main body portion 10, a motor case portion 11, and a handle portion 12.

また、本体部１０には、ダストケース２が着脱自在に取り付けられるとともに、接続口１０ａから吸い込まれた塵挨を含む空気をダストケース２に送り込む導入管１４（図４参照）を備えている。 Further, the main body 10 is provided with an introduction pipe 14 (see FIG. 4) in which the dust case 2 is detachably attached and air containing dust sucked from the connection port 10a is sent to the dust case 2.

モータケース部１１には、電動送風機４０（図６参照）と本体基板５０（図６参照）が内包されている。また、モータケース部１１の前面には、ダストケース２で集塵された後の清浄な空気が吸い込まれる円形の吸込口１１ａが形成されている。 The motor case portion 11 includes an electric blower 40 (see FIG. 6) and a main body substrate 50 (see FIG. 6). Further, on the front surface of the motor case portion 11, a circular suction port 11a is formed in which clean air collected by the dust case 2 is sucked.

ハンドル部１２は、本体部１０の後側に設けられ、略Ｌ字状に形成された把持部１２ａを有している。この把持部１２ａは、前後方向に直線状に延びる第１把持部１２ａ１と、略上下方向に直線状に延びる第２把持部１２ａ２と、を有している。第１把持部１２ａ１は、第２把持部１２ａ２よりも上側かつ前側に位置している。第２把持部１２ａ２は、上下方向に対して上部が前方に向くように若干傾斜している。また、第１把持部１２ａ１と第２把持部１２ａ２は略棒状かつ連続して形成されている。このように、第１把持部１２ａ１についても、第２把持部１２ａ２についてもそれぞれ直線状に構成することで、使用者が持ち手の位置を認識し易くなる。また、第１把持部１２ａ１と第２把持部１２ａ２とが直角に近い角度で折れ曲がるように接続されているので、第１把持部１２ａ１を把持しているときに第２把持部１２ａ２に手がずれ難く、逆に第２把持部１２ａ２を把持しているときに第１把持部１２ａ１に手がずれ難くなる。 The handle portion 12 is provided on the rear side of the main body portion 10 and has a grip portion 12a formed in a substantially L shape. The grip portion 12a has a first grip portion 12a1 extending linearly in the front-rear direction and a second grip portion 12a2 extending linearly in the substantially vertical direction. The first grip portion 12a1 is located above and in front of the second grip portion 12a2. The second grip portion 12a2 is slightly inclined so that the upper portion faces forward with respect to the vertical direction. Further, the first grip portion 12a1 and the second grip portion 12a2 are formed in a substantially rod shape and continuously. As described above, by forming both the first grip portion 12a1 and the second grip portion 12a2 in a linear shape, the user can easily recognize the position of the handle. Further, since the first grip portion 12a1 and the second grip portion 12a2 are connected so as to bend at an angle close to a right angle, the hand shifts to the second grip portion 12a2 when gripping the first grip portion 12a1. On the contrary, when the second grip portion 12a2 is gripped, it is difficult for the hand to slip to the first grip portion 12a1.

また、ハンドル部１２には、蓄電池３をロックするためのロック部材１３が設けられている。このロック部材１３は、ボタン型に形成されたものであり、揺動自在に支持されている。 Further, the handle portion 12 is provided with a lock member 13 for locking the storage battery 3. The lock member 13 is formed in a button shape and is supported so as to be swingable.

また、ハンドル部１２の第１把持部１２ａ１の上面には、操作ボタン１２ｂが設けられている。操作ボタン１２ｂは、例えば、「強」、「標準」、「切」の３つのボタンで構成されている。 Further, an operation button 12b is provided on the upper surface of the first grip portion 12a1 of the handle portion 12. The operation button 12b is composed of, for example, three buttons of "strong", "standard", and "off".

蓄電池３は、電動送風機４０（図６参照）などに電力を供給するものであり、リチウムイオン、ニッケル水素などの二次電池で構成されている。また、蓄電池３は、合成樹脂製の略半円筒状のケース３ａを有し、ケース３ａを前後方向にスライドさせることで本体部１０に対して着脱できる。 The storage battery 3 supplies electric power to an electric blower 40 (see FIG. 6) and the like, and is composed of a secondary battery such as lithium ion and nickel hydrogen. Further, the storage battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and can be attached to and detached from the main body 10 by sliding the case 3a in the front-rear direction.

また、ケース３ａの背面には、ロック部材１３が嵌合して本体部１０にロックされるロック凹部３ｇが形成されている。 Further, on the back surface of the case 3a, a lock recess 3g is formed in which the lock member 13 is fitted and locked to the main body 10.

図３は、本実施形態の電気掃除機からバッテリを取り外した状態を背面斜め後方から見た状態を示す斜視図である。 FIG. 3 is a perspective view showing a state in which the battery is removed from the vacuum cleaner of the present embodiment as viewed from diagonally rearward on the back surface.

本体部１０は、ハンドル部１２の下方において、左右両端から垂下する垂下部１０ｅ，１０ｅが形成されている。垂下部１０ｅの内壁面には、内方に向けて突出する突出部１０ｆが前後方向に延びて形成されている。なお、左側の突出部については図示を省略している。これにより、蓄電池３を掃除機本体１の背面側（後方）から前方に向けて、スライドレール３ｄ，３ｄを突出部１０ｆの上面側に摺動させることで、蓄電池３が本体部１０に支持される。そして、蓄電池３のケース３ａの背面部３ｍを垂下部１０ｅの後側の端面に突き当たることで、蓄電池３がロック部材１３によって本体部１０にロックされる。 The main body portion 10 is formed with hanging portions 10e and 10e hanging from both left and right ends below the handle portion 12. On the inner wall surface of the hanging portion 10e, a protruding portion 10f protruding inward is formed so as to extend in the front-rear direction. The protrusion on the left side is not shown. As a result, the storage battery 3 is supported by the main body 10 by sliding the slide rails 3d and 3d toward the upper surface side of the protruding portion 10f with the storage battery 3 facing forward from the back side (rear) of the vacuum cleaner main body 1. To. Then, by abutting the back surface portion 3 m of the case 3a of the storage battery 3 against the rear end surface of the hanging portion 10e, the storage battery 3 is locked to the main body portion 10 by the lock member 13.

図４は、図２のＸ方向矢視図である。 FIG. 4 is an arrow view in the X direction of FIG.

図４に示すように、ダストケース２は、サイクロン方式のものであり、導入管１４から吸込んだ塵埃を含む空気を、塵埃と空気とに分離し、塵埃を集める機能を有する。また、ダストケース２は、モータケース部１１の前方に軸方向を前後方向にして配置され、略円柱形状の収容部２ａを有している。また、ダストケース２の上面（側面）には、導入管１４と繋がる略矩形状の流入口２ｂ（図２参照）が形成されている。この流入口２ｂに流入した塵挨を含む空気は、旋回流となり、塵埃に遠心力が働き、ダストケース２内で塵挨と空気とに分離された後、塵埃が分離された空気がダストケース２の後部（背面）から排出される。 As shown in FIG. 4, the dust case 2 is of a cyclone type, and has a function of separating air including dust sucked from the introduction pipe 14 into dust and air and collecting dust. Further, the dust case 2 is arranged in front of the motor case portion 11 with the axial direction in the front-rear direction, and has a substantially cylindrical accommodating portion 2a. Further, a substantially rectangular inflow port 2b (see FIG. 2) connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust case 2. The air containing dust that has flowed into the inflow port 2b becomes a swirling flow, centrifugal force acts on the dust, and after being separated into dust and air in the dust case 2, the air from which the dust is separated is the dust case. It is discharged from the rear part (back surface) of 2.

ダストケース２内には、収容部２ａの軸方向の後端にフィルタ５（図６参照）が収容されている。このフィルタ５は、プリーツ状に折って構成されたものであり、フィルタ面積を大きくできるとともに、フィルタ５による圧力損失を低減することができる。 A filter 5 (see FIG. 6) is housed in the dust case 2 at the rear end in the axial direction of the housing part 2a. The filter 5 is formed by folding it into a pleated shape, so that the filter area can be increased and the pressure loss due to the filter 5 can be reduced.

また、フィルタ５は、例えば高密度のＨＥＰＡフィルタ（High Efficiency Particulate Air Filter）で構成されている。ＨＥＰＡフィルタとは、定格風量で粒径が０.３μｍの粒子に対して９９.９７％以上の粒子捕集率をもち、かつ初期圧力損失が２４５Ｐａ以下の性能を持つエアフィルタである。 Further, the filter 5 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The HEPA filter is an air filter having a particle collection rate of 99.97% or more and an initial pressure loss of 245 Pa or less with respect to particles having a rated air volume and a particle size of 0.3 μm.

また、ダストケース２の前面には、ダストケース２内に溜まった塵埃を廃棄する際に開閉する蓋２ｃがヒンジ部２ｄを介して回動自在に支持されている。また、蓋２ｃの上部には、蓋２ｃのロックを解除するための蓋ロック機構２ｅが設けられている。なお、ダストケース２の内部の機構については、特開２０１６−１３７１６５号公報に基づいて構成することができる。 Further, on the front surface of the dust case 2, a lid 2c that opens and closes when the dust accumulated in the dust case 2 is discarded is rotatably supported via a hinge portion 2d. Further, a lid lock mechanism 2e for unlocking the lid 2c is provided on the upper portion of the lid 2c. The internal mechanism of the dust case 2 can be configured based on JP-A-2016-137165.

図５は、本実施形態の電気掃除機の平面図である。 FIG. 5 is a plan view of the vacuum cleaner of the present embodiment.

本体部１０に形成された導入管１４は、一旦右斜め後方に延び、そして下方に延びて形成され、ダストケース２の流入口２ｂ（図２参照）と接続されている。これにより、ダストケース２の収容部２ａ内において旋回流を発生させることができ、遠心力による塵埃の分離を効果的に行うことができる。 The introduction pipe 14 formed in the main body 10 is formed so as to extend diagonally rearward to the right and then downward, and is connected to the inflow port 2b (see FIG. 2) of the dust case 2. As a result, a swirling flow can be generated in the accommodating portion 2a of the dust case 2, and dust can be effectively separated by centrifugal force.

ダストケース２および蓄電池３のそれぞれの幅は、本体部１０の幅Ｗよりも若干短く形成されている。換言すると、ダストケース２や蓄電池３が本体部１０の側方から突出しないように構成されている。これにより、使用者が左右どちらの手で持って掃除を行ったとしても、電気掃除機１００を前後方向に円滑に動かすことができ、使い勝手を向上できる。 The width of each of the dust case 2 and the storage battery 3 is formed to be slightly shorter than the width W of the main body 10. In other words, the dust case 2 and the storage battery 3 are configured so as not to protrude from the side of the main body 10. As a result, the vacuum cleaner 100 can be smoothly moved in the front-rear direction regardless of whether the user holds it with either the left or right hand for cleaning, and the usability can be improved.

図６は、図５のＶＩ−ＶＩ線断面図である。 FIG. 6 is a sectional view taken along line VI-VI of FIG.

図６に示すように、本体部１０のモータケース部１１には、電動送風機４０が収容されている。また、モータケース部１１内には、電動送風機４０の下方に、掃除機本体１を制御する本体基板５０（制御基板）が収容されている。 As shown in FIG. 6, the electric blower 40 is housed in the motor case portion 11 of the main body portion 10. Further, in the motor case portion 11, a main body board 50 (control board) for controlling the vacuum cleaner main body 1 is housed below the electric blower 40.

電動送風機４０は、回転駆動軸４０ａが前後方向を向くように横置きに配置されている。また、電動送風機４０から排出された空気は、矢印４１で示すように電動送風機４０の下方に配置された本体基板５０に流れ、本体基板５０を冷却するようになっている。 The electric blower 40 is arranged horizontally so that the rotary drive shaft 40a faces the front-rear direction. Further, the air discharged from the electric blower 40 flows to the main body substrate 50 arranged below the electric blower 40 as shown by an arrow 41, and cools the main body substrate 50.

本体基板５０は、上下に分割して２段に配置された上部基板５０ａと下部基板５０ｂとを有し、主に対向する面（上部基板５０ａの下面と下部基板５０ｂの上面）に各種部品が実装されている。電動送風機４０から排出された空気のほとんどは、各本体基板５０の対向配置された部品（発熱部品）を冷却するように流れる。また、本体基板５０は、難燃性の樹脂ケース５１で覆われており、電動送風機４０から排出された風（空気）は、樹脂ケース５１内を後側から前側に向けて流れ、そして、樹脂ケース５１の底面の下側から排気方向転向ダクト連通口２３を通って排気方向転向ダクト２０に流入し、排気口２１から排気されるようになっている。 The main board 50 has an upper board 50a and a lower board 50b which are divided into upper and lower parts and arranged in two stages, and various components are mainly placed on opposite surfaces (lower surface of the upper board 50a and upper surface of the lower board 50b). It is implemented. Most of the air discharged from the electric blower 40 flows so as to cool the parts (heat generating parts) arranged opposite to each other of the main body substrate 50. Further, the main body substrate 50 is covered with a flame-retardant resin case 51, and the wind (air) discharged from the electric blower 40 flows in the resin case 51 from the rear side to the front side, and the resin. From the lower side of the bottom surface of the case 51, the air flows into the exhaust direction turning duct 20 through the exhaust direction turning duct communication port 23, and is exhausted from the exhaust port 21.

排気方向転向ダクト２０は図６および図８に示すＱを軸に回動可能に本体部１０に取り付けられており、図７のようにＱを軸にして排気口２１の向きをかえることができる。
排気方向転向ダクト２０を図１の向きにして排気口２１を除機本体１の前方に向けると、電動送風機４０から排出された風（空気）は掃除機本体１の前方に噴き出し、掃除機本体１の前方の塵埃を吹き飛ばすブロアーとして機能する。このとき、電動送風機４０から排出された風（空気）はダストケース２によって塵埃が除去された空気であるため、被掃除箇所の塵埃を増やしてしまうことはない。 The exhaust direction turning duct 20 is rotatably attached to the main body 10 about the Q shown in FIGS. 6 and 8, and the direction of the exhaust port 21 can be changed around the Q as shown in FIG. ..
When the exhaust direction turning duct 20 is oriented in FIG. 1 and the exhaust port 21 is directed to the front of the vacuum cleaner main body 1, the wind (air) discharged from the electric blower 40 is blown out to the front of the vacuum cleaner main body 1. It functions as a blower that blows away the dust in front of 1. At this time, since the wind (air) discharged from the electric blower 40 is the air from which the dust has been removed by the dust case 2, the dust in the cleaned portion does not increase.

次に、排気方向転向ダクト２０を図７の向きにして排気口２１を掃除機本体１の左方に向けると、電動送風機４０から排出された風（空気）は掃除機本体１の左方に排気され、被掃除箇所の塵埃を意図せず吹き飛ばしてしまうのを防げる。 Next, when the exhaust direction turning duct 20 is oriented in FIG. 7 and the exhaust port 21 is directed to the left of the vacuum cleaner body 1, the wind (air) discharged from the electric blower 40 is directed to the left of the vacuum cleaner body 1. It is possible to prevent the dust in the area to be cleaned from being exhausted and being blown off unintentionally.

このようにして、ブロアー機能専用のホース等を持ち歩くことなく、排気方向転向ダクト２０の向きを変えるだけでブロアー機能の使用／不使用を切り替えることができる。 In this way, the use / non-use of the blower function can be switched by simply changing the direction of the exhaust direction turning duct 20 without carrying around a hose or the like dedicated to the blower function.

なお、図７では排気口２１を除機本体１の左方に向けているが、右方に向けた場合は掃除機本体１の右方に排気される。このように、排気の左右の向きを自由に変更できるので、使用者が右利きの場合でも左利きの場合でも、排気が直接使用者に当たるのを防止することもできる。 In FIG. 7, the exhaust port 21 is directed to the left side of the cleaner body 1, but when it is directed to the right, the exhaust port 21 is exhausted to the right side of the vacuum cleaner body 1. In this way, since the left and right directions of the exhaust can be freely changed, it is possible to prevent the exhaust from directly hitting the user regardless of whether the user is right-handed or left-handed.

次に、図９に本発明の第２の実施例における図５のＶＩ−ＶＩ線断面図を、また、図１０に図９のＶ−Ｖ断面を示す。図１０（ａ）は排気口２１を掃除機本体１の前方に向けてブロアー機能を使用する場合であり、図１０（ｂ）は排気口２１を掃除機本体１の左方に向け、ブロアー機能を使用しない場合である。この場合の前記同様に排気口２１を掃除機本体１の右方に向けてもよい。 Next, FIG. 9 shows a sectional view taken along line VI-VI of FIG. 5 in the second embodiment of the present invention, and FIG. 10 shows a sectional view taken along line V-V of FIG. FIG. 10A shows a case where the exhaust port 21 is directed toward the front of the vacuum cleaner body 1 to use the blower function, and FIG. 10B shows a case where the exhaust port 21 is directed to the left side of the vacuum cleaner body 1 and the blower function is used. Is not used. In this case, the exhaust port 21 may be directed to the right side of the vacuum cleaner main body 1 in the same manner as described above.

本体部１０から排気方向転向ダクト２０内に向けて流路幅規制壁２２を設け、Ｌ１＞Ｌ２かつＬ３＞Ｌ１／２となるように各寸法を設定することで、排気口２１を掃除機本体１の前方に向けた場合（図１０（ａ））の排気流路幅はＬ２となり、排気口２１を掃除機本体１の左方あるいは右方に向けた場合（図１０（ｂ））の排気流路幅はＬ１となり、排気口２１を掃除機本体１の前方に向けてブロアー機能を使用するときは排気流路幅を絞って排気流速を上げた強力なブロアーとすることができ、排気口２１を掃除機本体１の左方あるいは右方に向けてブロアー機能を使用しないときは排気流路幅を広くして排気流速を落とし、周囲の物品を意図せず吹き飛ばすのを防ぐことができる。 The exhaust port 21 is set as the vacuum cleaner main body by providing the flow path width regulating wall 22 from the main body 10 toward the inside of the exhaust direction turning duct 20 and setting each dimension so that L1> L2 and L3> L1 / 2. The exhaust flow path width is L2 when facing the front of 1 (FIG. 10 (a)), and the exhaust when the exhaust port 21 is directed to the left or right of the vacuum cleaner body 1 (FIG. 10 (b)). The flow path width is L1, and when the blower function is used with the exhaust port 21 facing the front of the vacuum cleaner body 1, the exhaust flow path width can be narrowed to make a powerful blower with an increased exhaust flow velocity. When the blower function is not used with the 21 directed to the left or right of the vacuum cleaner body 1, the width of the exhaust flow path is widened to reduce the exhaust flow velocity, and it is possible to prevent the surrounding articles from being unintentionally blown away.

Ｌ１、Ｌ２、Ｌ３の寸法の例を図１１に示す。図１１（ａ）は排気口２１を掃除機本体１の前方に向けてブロアー機能を使用する場合であり、図１１（ｂ）は排気口２１を掃除機本体１の左方に向け、ブロアー機能を使用しない場合である。この場合、ブロアー機能を使用するときの排気流路幅は、使用しないときに比べて１５／４７≒０．３２倍に狭まり、それにより排気流速を４７／１５≒３．１倍に上げた強力なブロアーとすることができる。 An example of the dimensions of L1, L2, and L3 is shown in FIG. FIG. 11A shows a case where the blower function is used with the exhaust port 21 facing the front of the vacuum cleaner body 1, and FIG. 11B shows a blower function with the exhaust port 21 facing the left side of the vacuum cleaner body 1. Is not used. In this case, the width of the exhaust flow path when the blower function is used is narrowed by 15/47 ≈ 0.32 times compared to when it is not used, thereby increasing the exhaust flow velocity by 47/15 ≈ 3.1 times. Can be a blower.

次に、図１２に本発明の第３の実施例における図５のＶＩ−ＶＩ線断面図を示す。図１２（ａ）は排気口２１を掃除機本体１の前方に向けてブロアー機能を使用する場合であり、図１２（ｂ）は排気口２１を掃除機本体１の左方に向け、ブロアー機能を使用しない場合である。流路幅規制壁２２の前方開口（寸法Ｌ２）以外にフィルター部材２４を設けることで、排気口２１を掃除機本体１の前方に向けてブロアー機能を使用するときは排気流速を上げた強力なブロアーとすることができ、排気口２１を掃除機本体１の左方あるいは右方に向けてブロアー機能を使用しないときは排気流速を落とし、かつフィルター部材２４により排気を清浄にすることができる。 Next, FIG. 12 shows a sectional view taken along line VI-VI of FIG. 5 in the third embodiment of the present invention. FIG. 12A shows a case where the exhaust port 21 is directed to the front of the vacuum cleaner body 1 to use the blower function, and FIG. 12B shows a case where the exhaust port 21 is directed to the left of the vacuum cleaner body 1 to use the blower function. Is not used. By providing the filter member 24 in addition to the front opening (dimension L2) of the flow path width regulating wall 22, when the exhaust port 21 is directed to the front of the vacuum cleaner main body 1 and the blower function is used, the exhaust flow velocity is increased. It can be a blower, and when the exhaust port 21 is directed to the left or right of the vacuum cleaner body 1 and the blower function is not used, the exhaust flow velocity can be reduced and the exhaust can be cleaned by the filter member 24.
