Description

本発明の実施形態は、電動送風機と集塵部とを備える電気掃除機に関する。 An embodiment of the present invention relates to an electric vacuum cleaner including an electric blower and a dust collector.

スティック型の電気掃除機は、掃除機本体に設けられた把持部を使用者が把持して使用する。掃除機本体には、電動送風機、電池、集塵部等の重量物が配置されている。従来、集塵部と電動送風機とを上下に並んで配置するとともに、集塵部の軸方向に対して電動送風機の軸方向を傾けることで、重量バランスを取るものがある。しかしながら、この配置の場合には、集塵部から電動送風機に吸い込まれる風路が複雑に屈曲することから、吸引効率を向上することが容易でない。吸引効率を向上する場合、集塵部と電動送風機とを同軸上に配置し、風路を直線に近づけることが好ましい。しかしながら、この配置の場合には、重量物が長手方向に延びて配置されることから、重量バランスが悪く、小型化が容易でない。 The stick-type vacuum cleaner is used by the user by gripping the grip portion provided on the vacuum cleaner body. Heavy objects such as an electric blower, a battery, and a dust collector are arranged on the vacuum cleaner body. Conventionally, the dust collector and the electric blower are arranged one above the other, and the weight is balanced by tilting the axial direction of the electric blower with respect to the axial direction of the dust collector. However, in the case of this arrangement, it is not easy to improve the suction efficiency because the air passage sucked from the dust collecting portion into the electric blower is complicatedly bent. In order to improve the suction efficiency, it is preferable to arrange the dust collector and the electric blower coaxially so that the air passage is close to a straight line. However, in the case of this arrangement, since the heavy object is arranged so as to extend in the longitudinal direction, the weight balance is poor and miniaturization is not easy.

また、本実施形態において、図３に示すように、電池４、電動送風機３、及び、集塵部２は、第二方向にずれずに位置している。 Further, in the present embodiment, as shown in FIG. 3, the battery 4, the electric blower 3, and the dust collecting unit 2 are located without being displaced in the second direction.

本実施形態において、電池４は、集塵部２及び電動送風機３よりも重量が大きい重量物である。電池４は、複数のセルが電気的に直列に接続されて構成された電池パックである。電池４は、充電可能な二次電池が好適に用いられる。 In the present embodiment, the battery 4 is a heavy object that is heavier than the dust collector 2 and the electric blower 3. The battery 4 is a battery pack composed of a plurality of cells electrically connected in series. As the battery 4, a rechargeable secondary battery is preferably used.

図１に示すように、掃除機本体１には、制御手段５が収容されている。制御手段５は、任意の位置に配置されてよいが、本実施形態では、電動送風機３に対し、集塵部２とは反対側に配置されている。つまり、制御手段５は、電動送風機３に対し、第一方向の他方側に配置されている。制御手段５は、電動送風機３から図３に示す本体排気口123への排気風により冷却される位置に配置されている。 As shown in FIG. 1, the vacuum cleaner main body 1 includes a control means 5. The control means 5 may be arranged at an arbitrary position, but in the present embodiment, the control means 5 is arranged on the side opposite to the dust collecting unit 2 with respect to the electric blower 3. That is, the control means 5 is arranged on the other side of the first direction with respect to the electric blower 3. The control means 5 is arranged at a position where it is cooled by the exhaust air from the electric blower 3 to the main body exhaust port 123 shown in FIG.

次に、一実施形態の動作を説明する。 Next, the operation of one embodiment will be described.

図１に示すように集塵部２を掃除機本体１に取り付けると、本体吸込口101が集塵部２の吸込側に連通し、電動送風機３の吸込側が集塵部２の排気側に連通することで、本体吸込口101から集塵部２、電動送風機３、図３に示す本体排気口123に至る風路が形成される。 When the dust collecting unit 2 is attached to the vacuum cleaner main body 1 as shown in FIG. 1, the main body suction port 101 communicates with the suction side of the dust collecting unit 2, and the suction side of the electric blower 3 communicates with the exhaust side of the dust collecting unit 2. As a result, an air passage is formed from the main body suction port 101 to the dust collector 2, the electric blower 3, and the main body exhaust port 123 shown in FIG.

本実施形態では、図１に示すように、集塵部２を掃除機本体１に取り付けると、集塵部２の導入口23が掃除機本体１の接続開口部103に接続されて集塵部２の吸込側が吸込風路102と連通され、集塵部２の排気口24が掃除機本体１の接続口121に接続されて集塵部２の排気側が風路部122と連通される。 In the present embodiment, as shown in FIG. 1, when the dust collecting portion 2 is attached to the vacuum cleaner main body 1, the introduction port 23 of the dust collecting portion 2 is connected to the connection opening 103 of the vacuum cleaner main body 1 to be connected to the dust collecting portion. The suction side of 2 is communicated with the suction air passage 102, the exhaust port 24 of the dust collecting portion 2 is connected to the connection port 121 of the vacuum cleaner main body 1, and the exhaust side of the dust collecting portion 2 is communicated with the air passage portion 122.

使用者が把持部14を把持し、設定手段141を操作すると、設定手段141の操作に応じて制御手段５が電動送風機３を動作させる。電動送風機３の動作により生じた負圧が本体吸込口101を介して作用することで被掃除面から含塵空気を集塵部２に吸い込む。 When the user grips the grip portion 14 and operates the setting means 141, the control means 5 operates the electric blower 3 in response to the operation of the setting means 141. The negative pressure generated by the operation of the electric blower 3 acts through the main body suction port 101 to suck the dust-containing air from the surface to be cleaned into the dust collecting unit 2.

下方の被掃除面を掃除する場合、把持部14を把持した使用者から見て、第一方向の一方側が前側、他方側が後側、第二方向の一方側が左側、他方側が右側、第三方向の一方側が上側、他方側が下側となる。使用者は、把持部14によって電気掃除機VCを前後に移動させながら、本体吸込口101、又は、本体吸込口101に接続された風路体によって被掃除面の塵埃を吸い込ませる。 When cleaning the lower surface to be cleaned, one side in the first direction is the front side, the other side is the rear side, one side in the second direction is the left side, the other side is the right side, and the third direction when viewed from the user who grips the grip portion 14. One side is the upper side and the other side is the lower side. The user sucks the dust on the surface to be cleaned by the main body suction port 101 or the air passage body connected to the main body suction port 101 while moving the vacuum cleaner VC back and forth by the grip portion 14.

集塵部２で塵埃が分離捕集された空気は、電動送風機３に吸い込まれ、図３に示す本体排気口123から排気風として排出される。電動送風機３の排気にしたがい、電池４の熱が電池４の全体から吸引されて本体排気口123から掃除機本体１の外部に排気風とともに排出され、電池４が冷却される。 The air in which the dust is separated and collected by the dust collecting unit 2 is sucked into the electric blower 3 and discharged as exhaust air from the main body exhaust port 123 shown in FIG. According to the exhaust of the electric blower 3, the heat of the battery 4 is sucked from the entire battery 4 and discharged from the main body exhaust port 123 to the outside of the vacuum cleaner main body 1 together with the exhaust air, and the battery 4 is cooled.

このとき、電動送風機３と集塵部２との互いの軸方向が平行で、かつ、互いの中心軸34，21をずらして配置するとともに、電動送風機３の少なくとも一部を集塵部２の軸方向の投影PR内に位置させていることで、集塵部２から電動送風機３への吸引効率を大きく低下させることなく、集塵部２に対する電動送風機３のずれ方向とは反対側に空間を形成して配置効率を高めることができ、電気掃除機VCの小型化が可能になる。 At this time, the electric blower 3 and the dust collector 2 are arranged so that their axial directions are parallel to each other and their central axes 34 and 21 are offset from each other, and at least a part of the electric blower 3 is arranged in the dust collector 2. By locating it within the projected PR in the axial direction, the space is on the side opposite to the displacement direction of the electric blower 3 with respect to the dust collector 2 without significantly reducing the suction efficiency from the dust collector 2 to the electric blower 3. Can be formed to improve the placement efficiency, and the electric vacuum cleaner VC can be miniaturized.

電動送風機３の中心軸34が集塵部２の軸方向の投影PR内に位置するように配置することで、集塵部２から電動送風機３への吸引効率の低下をより抑制し、性能を維持できる。 By arranging the central axis 34 of the electric blower 3 so as to be located within the projected PR in the axial direction of the dust collector 2, the decrease in suction efficiency from the dust collector 2 to the electric blower 3 is further suppressed, and the performance is improved. Can be maintained.

電動送風機３の全体を集塵部２の軸方向の投影PR内に位置するように配置することで、電気掃除機VCのより一層の小型化が可能になる。 By arranging the entire electric blower 3 so as to be located within the projected PR in the axial direction of the dust collector 2, the vacuum cleaner VC can be further miniaturized.

電池４の少なくとも一部を、集塵部２の中心軸21を基準にして電動送風機３の中心軸34とは反対側の位置で集塵部２の軸方向の投影PR内に配置することで、集塵部２に対する電動送風機３のずれ方向とは反対側の空間を利用し、電気掃除機VCの小型化が可能になる。 By arranging at least a part of the battery 4 in the axial projection PR of the dust collecting unit 2 at a position opposite to the central axis 34 of the electric blower 3 with reference to the central axis 21 of the dust collecting unit 2. By utilizing the space on the side opposite to the displacement direction of the electric blower 3 with respect to the dust collector 2, the electric vacuum cleaner VC can be miniaturized.

特に、掃除機本体１の内部に電動送風機３及び電池４を収容する場合、掃除機本体１の内部の限られた空間を有効に使うことができ、電気掃除機VCの小型化が可能になる。 In particular, when the electric blower 3 and the battery 4 are housed inside the vacuum cleaner main body 1, the limited space inside the vacuum cleaner main body 1 can be effectively used, and the electric vacuum cleaner VC can be miniaturized. ..

電池４の長手方向を電動送風機３の軸方向に対し平行に配置することで、電動送風機３と電池４とをコンパクトに配置できるとともに、電池４からの発熱を電動送風機３によって容易に本体排気口123から排出可能になる。 By arranging the longitudinal direction of the battery 4 parallel to the axial direction of the electric blower 3, the electric blower 3 and the battery 4 can be arranged compactly, and the heat generated from the battery 4 can be easily generated by the electric blower 3 from the main body exhaust port. It becomes possible to discharge from 123.

電動送風機３と電池４とを集塵部２の軸方向と交差する方向で互いにオーバーラップする位置に配置することで、掃除機本体１を第一方向に長くすることなく電動送風機３と電池４とを配置可能となり、電気掃除機VCの小型化が可能になる。 By arranging the electric blower 3 and the battery 4 at positions where they overlap each other in the direction intersecting the axial direction of the dust collector 2, the electric blower 3 and the battery 4 do not lengthen the vacuum cleaner body 1 in the first direction. And can be arranged, and the vacuum cleaner VC can be miniaturized.

特に、把持部14を把持した状態で下方の被掃除面を掃除する場合、電動送風機３が電池４の上方に位置するため、電池４の発熱により暖まった空気が電動送風機３の方へと上昇するので、電動送風機３が排気風とともに電池４の熱を掃除機本体１から排出できる。 In particular, when cleaning the lower surface to be cleaned while gripping the grip portion 14, since the electric blower 3 is located above the battery 4, the air warmed by the heat generated by the battery 4 rises toward the electric blower 3. Therefore, the electric blower 3 can exhaust the heat of the battery 4 together with the exhaust air from the vacuum cleaner main body 1.

把持部14を電動送風機３と集塵部２とに跨る位置に配置することで、把持部14を把持した状態で電動送風機３と集塵部２とがバラストとして作用し、重量バランスが取りやすくなって、電気掃除機VCの操作性を向上できる。本実施形態では、把持部14を電動送風機３と集塵部２及び電池４とに跨る位置に配置することで、把持部14を把持した状態で電動送風機３と集塵部２及び電池４とがバラストとして作用し、より重量バランスが取りやすくなって、電気掃除機VCの操作性を向上できる。 By arranging the grip portion 14 at a position straddling the electric blower 3 and the dust collector 2, the electric blower 3 and the dust collector 2 act as ballasts while gripping the grip portion 14, and it is easy to balance the weight. Therefore, the operability of the electric vacuum cleaner VC can be improved. In the present embodiment, by arranging the grip portion 14 at a position straddling the electric blower 3, the dust collector 2, and the battery 4, the electric blower 3, the dust collector 2, and the battery 4 are held in a state where the grip portion 14 is gripped. Acts as a ballast, making it easier to balance the weight and improve the operability of the vacuum cleaner VC.

本体吸込口101が把持部14の一端側に位置し、その中心軸105が把持部14とは反対側の位置で集塵部２の中心軸21に対し交差するように配置することで、把持部14を把持して下方の被掃除面を掃除する際に、把持部14を把持した手を大きく傾けることなく本体吸込口101を被掃除面側に向けることができる。そのため、把持部14の下方に重量物である集塵部２、電動送風機３、及び、電池４が位置する位置関係を維持した状態で、つまり重量バランスが取れた状態で、下方の被掃除面を掃除する操作が可能となり、電気掃除機VCの操作性が良好となる。 The main body suction port 101 is located on one end side of the grip portion 14, and the central axis 105 is arranged so as to intersect the central axis 21 of the dust collecting portion 2 at a position opposite to the grip portion 14. When gripping the portion 14 to clean the lower surface to be cleaned, the main body suction port 101 can be directed toward the surface to be cleaned without significantly tilting the hand holding the grip portion 14. Therefore, the lower surface to be cleaned is maintained in a state where the heavy dust collector 2, the electric blower 3, and the battery 4 are located below the grip portion 14, that is, in a state where the weight is balanced. The operation of cleaning is possible, and the operability of the electric vacuum cleaner VC is improved.

また、把持部14を把持した状態で下方の被掃除面を掃除する場合、本体排気口123が掃除機本体１の上部側に位置して被掃除面に直接対向しないため、電動送風機３からの排気風が掃除機本体１の下方に出ない。したがって、特に風路体を使用せずに掃除機本体１のみで掃除をする際に、掃除機本体１が被掃除面に接近していても、排気風によって被掃除面の塵埃を吹き飛ばしにくい。 Further, when cleaning the lower surface to be cleaned while gripping the grip portion 14, the exhaust port 123 of the main body is located on the upper side of the vacuum cleaner main body 1 and does not directly face the surface to be cleaned, so that the electric blower 3 is used. Exhaust air does not come out below the vacuum cleaner body 1. Therefore, when cleaning with only the vacuum cleaner main body 1 without using the air passage body, even if the vacuum cleaner main body 1 is close to the surface to be cleaned, it is difficult for the exhaust air to blow off the dust on the surface to be cleaned.
