Abstract
Description
本発明は、電動送風機を備える電気掃除機に関する。 The present invention relates to a vacuum cleaner including an electric blower.
一般的な電気掃除機は、電動送風機の運転により吸口から吸い込んだ含塵空気を掃除機本体に導き、この掃除機本体内の集塵部を通して塵埃が捕捉され、清浄になった空気を掃除機本体外に排気する構成となっている。 General vacuum cleaners guide the dust-containing air sucked from the suction port by operating the electric blower to the main body of the vacuum cleaner, and dust is trapped through the dust collecting part in the main body of the vacuum cleaner. It is configured to exhaust outside the body.
集塵部は、紙フィルタによるろ過によって塵埃を捕捉し、清浄になった空気を掃除機本体外に排気する方式と、集塵フィルタによるろ過によって塵埃を捕捉し、清浄になった空気を掃除機本体外に排気する方式と、サイクロン分離筒による遠心分離によって清浄になった空気と塵埃とを分離し、清浄になった空気は掃除機本体外へ、塵埃は集塵フィルタを備えた集塵部へ集塵するサイクロン分離方式がある。 The dust collection unit captures dust by filtering with a paper filter, exhausts the cleaned air out of the main body of the cleaner, and traps dust by filtering with a dust collection filter to clean the cleaned air. Separates air and dust that has been cleaned by centrifugal separation using a cyclone separation cylinder, and exhausted outside the main body. The cleaned air is removed from the main body of the vacuum cleaner, and the dust is a dust collector with a dust collecting filter. There is a cyclone separation system that collects dust.
排気をより清浄にするためには塵埃を十分に捕捉する必要がある。電動送風機を通過した空気は掃除機本体外に排気されてしまうため紙フィルタ、及び集塵フィルタは電動送風機の前に設ける構成となっている。 In order to make the exhaust gas cleaner, it is necessary to sufficiently capture dust. Since the air that has passed through the electric blower is exhausted outside the main body of the cleaner, the paper filter and the dust collection filter are provided in front of the electric blower.
また、吸込み性能の向上と騒音低減を図るために電動送風機と防振パッキンとの間に、ファンケースに設けた吸気口と同等の高さを有する壁面を設ける構成となっている。 Further, in order to improve the suction performance and reduce the noise, a wall surface having a height equivalent to the intake port provided in the fan case is provided between the electric blower and the vibration-proof packing.
また、前記電動送風機内に流入する空気の効率を高めるために例えば特許文献１に開示されているように、本体ケースと、本体ケースの後ろ側に内置される電動送風機と、本体ケースと電動送風機の中間に防振パッキンを設けた電気掃除機において防振パッキンと電動送風機との間に、アダプタを設けた技術が開示されている。 Moreover, in order to improve the efficiency of the air flowing into the electric blower, for example, as disclosed in Patent Document 1, a main body case, an electric blower placed behind the main body case, the main body case, and the electric blower In a vacuum cleaner provided with an anti-vibration packing in the middle thereof, a technique is disclosed in which an adapter is provided between the anti-vibration packing and the electric blower.
上記従来の紙フィルタ方式、及び集塵フィルタ方式の電気掃除機において、排気をより清浄に保つためには、紙フィルタ、及び集塵フィルタの目を細かいものにし、塵埃を通さないものとする必要がある。しかし目が細かいフィルタは通気抵抗が大きく、圧力損失が高くなる。圧力損失が高くなると、掃除機本来の性能である吸引力が低下し、ゴミが吸わない等の不具合が発生する恐れがある。 In the above conventional paper filter type and dust collection filter type vacuum cleaner, in order to keep the exhaust air cleaner, it is necessary to make the paper filter and dust collection filter finer and impervious to dust. There is. However, a fine filter has high ventilation resistance and high pressure loss. If the pressure loss increases, the suction force, which is the original performance of the vacuum cleaner, may be reduced, and problems such as the inability to suck dust may occur.
このため本体構造としては、圧力損失を低減するため、本体と接続しているホースや、その先に吸口と連結している伸縮継ぎ手管の内外径を大きくする必要があるが、ホース、伸縮継ぎ手管の径拡大は使い勝手の悪さ、本体構造の大幅変更等、使う側も造る側も非常に悪影響を及ぼす。 For this reason, in order to reduce the pressure loss, the main body structure needs to increase the inner and outer diameters of the hose connected to the main body and the expansion joint pipe connected to the suction port at the end. Enlarging the diameter of the tube has a very bad influence on both the user side and the building side, such as poor usability and major changes in the body structure.
その他の方法として、電動送風機の性能向上による吸引力の低下防止策があるが、電動送風機の性能向上は非常に難しく、仮に性能向上しても騒音、振動大等の恐れが生じる。 As another method, there is a measure for preventing a decrease in suction force by improving the performance of the electric blower, but it is very difficult to improve the performance of the electric blower, and even if the performance is improved, there is a risk of noise and vibration.
特許文献１に記載の技術では、空気の乱れを防ぐアダプタを防振パッキンと電動送風機の間に設けているが、電動送風機のファンケースを製作する際に多少歪みが生じた場合、アダプタとファンケースの接触面において気密がとれず、本来の吸気口以外から電動送風機に空気が流入してしまい、吸込仕事率が低下してしまう恐れがある。 In the technique described in Patent Document 1, an adapter that prevents air turbulence is provided between the anti-vibration packing and the electric blower. However, if some distortion occurs when manufacturing the fan case of the electric blower, the adapter and the fan There is a risk that airtightness may not be obtained at the contact surface of the case, and air may flow into the electric blower from other than the original air inlet, resulting in a reduction in suction work rate.
本発明は、吸引力を向上させる電気掃除機を提供することを目的とする。 An object of this invention is to provide the vacuum cleaner which improves attraction | suction power.
本発明は、本体ケースと電動送風機の間に防振パッキンを備えた電気掃除機において、前記防振パッキンと前記電動送風機の間に、アダプタを配置し、前記アダプタと前記電動送風機との間に、環形状の気密部材を設けたことを特徴とする。 The present invention relates to a vacuum cleaner provided with an anti-vibration packing between a main body case and an electric blower, wherein an adapter is disposed between the anti-vibration packing and the electric blower, and the adapter and the electric blower are disposed between the adapter and the electric blower. An annular airtight member is provided.
本発明によれば、本体構造の大幅改造を行わず、電動送風機の性能も現状態で、掃除機本来の性能である吸引力の向上させる電気掃除機を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the main body structure is not remodeled, the performance of an electric blower is the present state, and the vacuum cleaner which improves the attraction | suction force which is the original performance of a cleaner can be provided.

Have
図３に示すように、電動送風機１２の吸気力による含塵空気は、吸口５から吸気することによって吸気流と共に塵埃を吸い込み、吸い込んだ含塵空気を伸縮継ぎ手４と手元操作管３、及びホース２を介して掃除機本体１に流入する。流入した含塵空気は、ホース口継ぎ手６から集塵フィルタ１４を通過し、電動送風機保護フィルタ１５を介し電動送風機１２に吸い込まれる。この時塵埃は集塵フィルタ１４、及び電動送風機保護フィルタ１５にて捕捉し、清浄になった空気は電動送風機１２を通過し、電動送風機支持部材１６を介し、排気フィルタ１１、及び車輪８から排気される。 As shown in FIG. 3, the dust-containing air due to the suction force of the electric blower 12 sucks dust together with the intake air flow by sucking from the suction port 5, and the sucked dust-containing air is sucked into the expansion joint 4, the hand control tube 3, and the hose. It flows into the cleaner body 1 through 2. The inflowing dust-containing air passes through the dust collecting filter 14 from the hose joint 6 and is sucked into the electric blower 12 through the electric blower protection filter 15. At this time, dust is captured by the dust collection filter 14 and the electric blower protection filter 15, and the purified air passes through the electric blower 12 and is exhausted from the exhaust filter 11 and the wheels 8 through the electric blower support member 16. Is done.
図４は掃除機本体１の断側面図である。本体ケース７の下部には、走行用に車輪８とは別にキャスター１７を有し、走行の補助をしている。本体ケース７と電動送風機１２の間には、本体ケース７と電動送風機１２の気密を保持するための防振パッキン１８を有する。この防振パッキン１８は電動送風機１２運転時の振動を本体ケース７に伝達しないような役割も兼ねている。電動送風機１２は、吸引ファン部１９と電動機部２０を有し、吸引ファン部１９を前側に、電動機部２０を後側に、かつ水平に置かれるように配置される。
吸引ファン部１９の前側に備わる吸込口（電動送風機１２の吸込口、後述）は、集塵フィルタ１４の背面中央側に向くように置かれる。
FIG. 4 is a sectional side view of the cleaner body 1. In the lower part of the main body case 7, a caster 17 is provided separately from the wheels 8 for traveling to assist traveling. Between the main body case 7 and the electric blower 12, an anti-vibration packing 18 for maintaining the airtightness of the main body case 7 and the electric blower 12 is provided. The anti-vibration packing 18 also serves to prevent vibrations during operation of the electric blower 12 from being transmitted to the main body case 7. The electric blower 12 includes a suction fan unit 19 and an electric motor unit 20, and is arranged so that the suction fan unit 19 is placed on the front side, the motor unit 20 is placed on the rear side, and horizontally.
A suction port (a suction port of the electric blower 12, which will be described later) provided on the front side of the suction fan unit 19 is placed so as to face the center of the back surface of the dust collection filter 14.
図５は電動送風機ユニットの斜視図である。本実施例において、電動送風機ユニットは、電動送風機１２と、気密部材２５と、アダプタ３０と、防振パッキン１８と、接触リブ２４と、からなる。電動送風機１２は吸引ファン部１９に送風機吸込口２１を有し、電動機部２０に通電することにより、吸引ファン部１９内部の吸引ファン回転体２２を回転させ、送風機吸込口２１へと吸気する。送風機吸込口２１は吸引ファン回転体２２との気密を保持するため、送風機吸込口２１と吸引ファン回転体２２の間にはシールされており、送風機吸込口２１の形状はシール材を埋め込むため送風機突出部２３として突出した形状となる。 FIG. 5 is a perspective view of the electric blower unit. In the present embodiment, the electric blower unit includes the electric blower 12, the airtight member 25, the adapter 30, the vibration-proof packing 18, and the contact rib 24. The electric blower 12 has a blower suction port 21 in the suction fan unit 19. When the electric motor unit 20 is energized, the suction fan rotating body 22 inside the suction fan unit 19 is rotated and sucked into the blower suction port 21. The blower suction port 21 is sealed between the blower suction port 21 and the suction fan rotator 22 in order to maintain airtightness with the suction fan rotator 22, and the shape of the blower suction port 21 embeds a sealing material to blow the blower. The protruding portion 23 has a protruding shape.
図１、図４、及び図５に示すように、電動送風機１２により送風機吸込口２１へと吸い込まれる吸気は、外気から直接吸い込まれるわけではなく、吸口５、伸縮継ぎ手４、ホース２、ホース口継ぎ手６を通過し、本体ケース７でその吸気流路は拡大する。本体ケース７には吸気の抵抗となる集塵フィルタ１４と電動送風機保護フィルタ１５が備えられており、電動送風機１２の吸気力を妨げている。また本体ケース７により拡大した吸気通路は、電動送風機１２の送風機吸込口２１にて吸気流路は縮小し、空気は電動送風機１２内部に取り込まれ、排気として機外に排出される。 As shown in FIGS. 1, 4, and 5, the air sucked into the blower suction port 21 by the electric blower 12 is not directly sucked from the outside air, but the suction port 5, the expansion joint 4, the hose 2, and the hose port. Passing through the joint 6, the main body case 7 expands its intake passage. The main body case 7 is provided with a dust collection filter 14 and an electric blower protection filter 15 that serve as resistance to intake air, and hinders the intake force of the electric blower 12. The intake passage enlarged by the main body case 7 is reduced in the intake passage at the blower suction port 21 of the electric blower 12, and air is taken into the electric blower 12 and discharged outside the machine as exhaust.
この時、電動送風機１２に吸い込まれる空気は、本体ケース７による吸気流路の拡大によって空気圧拡大損失が発生し、拡大損失から電動送風機１２の吸気力の低下が発生する。これと同様に、電動送風機１２の送風機吸込口２１に吸い込まれる空気は、本体ケース７から送風機吸込口２１へと吸気流路が縮小することによって空気圧縮小損失が発生し、縮小損失から電動送風機１２の吸気力の低下が発生する。吸気による流体の概念は、管路の開口端と外部の圧力差によって空気を吸い込むことになり、直接管路の開口端に向かうことはない。このことから、電動送風機１２に吸い込まれる空気の流れは、本体ケース７から直接送風機吸込口２１に吸い込まれるもののほかに、吸引ファン部１９の表面に当たってから送風機突出部２３を乗り越えて送風機吸込口２１に流入する空気や、防振パッキン１８と吸引ファン部１９の表面に入り込んでから、送風機突出部２３を乗り越えて送風機吸込口２１に流入する空気がある。これら本体ケース７から直接送風機吸込口２１に吸い込まれる以外の空気は、気流が乱れるため乱流となり、電動送風機１２の吸気力の妨げとなる。そこで、アダプタ３０を追加し流入する空気により発生する乱流を低減して空気圧縮小損失による電動送風機１２の吸気力低減を回避した。しかし、アダプタ３０とファンケース２６の接触面において、電動送風機１２のファンケース２６を製作する際に歪みが生じた場合、気密が漏れて本来の吸気口以外から電動送風機１２に空気が流入してしまい、吸気力の妨げとなる。 At this time, the air sucked into the electric blower 12 causes an air pressure expansion loss due to the expansion of the intake flow path by the main body case 7, and the intake force of the electric blower 12 is reduced due to the expansion loss. Similarly, the air sucked into the blower suction port 21 of the electric blower 12 causes an air pressure reduction loss when the intake passage is reduced from the main body case 7 to the blower suction port 21, and the electric blower 12 is generated from the reduction loss. The intake power of the engine is reduced. The concept of fluid by suction is that air is sucked in due to a pressure difference between the open end of the pipeline and the outside, and does not go directly to the open end of the pipeline. For this reason, the flow of air sucked into the electric blower 12 hits the surface of the suction fan portion 19 after getting into the blower suction port 21 directly from the main body case 7, and then gets over the blower protrusion 23 and blower suction port 21. And air that enters the surfaces of the vibration-proof packing 18 and the suction fan unit 19 and then passes over the blower protrusion 23 and flows into the blower suction port 21. Air other than those directly sucked into the blower inlet 21 from the main body case 7 is turbulent because the airflow is disturbed, and the air intake force of the electric blower 12 is hindered. Therefore, the adapter 30 is added to reduce the turbulent flow generated by the incoming air, thereby avoiding the reduction of the intake force of the electric blower 12 due to the air pressure reduction loss. However, if distortion occurs when the fan case 26 of the electric blower 12 is produced on the contact surface between the adapter 30 and the fan case 26, airtightness leaks and air flows into the electric blower 12 from other than the original air inlet. Therefore, the intake force is hindered.
本発明は、アダプタ３０とファンケース２６の接触面がファンケース２６を製作する際に生じた歪みにより生じた気密漏れを防止し、電動送風機１２の吸気力低減を回避するためのものである。 In the present invention, the contact surface between the adapter 30 and the fan case 26 prevents an airtight leak caused by distortion generated when the fan case 26 is manufactured, and avoids a reduction in intake force of the electric blower 12.
図６は、本発明の実施例に係る接触リブ２４と、電動送風機ユニットの断側面図である。アダプタ３０は一体成形品であり、その各部は電動送風機１２と防振パッキン１８間に位置するアダプタ外周円３０ａ、防振パッキン１８を取り付けた時、その表面が防振パッキン１８と同じ高さになるよう形成されたアダプタ表面３０ｂ、アダプタ表面３０ｂより前に位置され、電動送風機１２の送風機突出部２３を隠すように構成されたアダプタ突出部３０ｃ、アダプタ突出部３０ｃから電動送風機１２の送風機吸込口２１に滑らかな曲線になるよう、送風機突出部２３の径よりも大きな径を形とったアダプタ吸込口３０ｄ、電動送風機１２の送風機突出部２３と同形状に形成されたアダプタ位置合わせ３０ｅにより構成されている。 FIG. 6 is a sectional side view of the contact rib 24 and the electric blower unit according to the embodiment of the present invention. The adapter 30 is an integrally molded product, and each part thereof has the same height as the anti-vibration packing 18 when the adapter outer circumference circle 30a located between the electric blower 12 and the anti-vibration packing 18 is attached. Adapter surface 30b formed to be, adapter protrusion 30c that is positioned before adapter surface 30b and is configured to hide fan protrusion 23 of electric blower 12, fan inlet of electric fan 12 from adapter protrusion 30c The adapter inlet 30d having a diameter larger than the diameter of the blower protrusion 23 and the adapter alignment 30e formed in the same shape as the blower protrusion 23 of the electric blower 12 so as to have a smooth curve in FIG. ing.
アダプタ３０のアダプタ外周円３０ａは、電動送風機１２と防振パッキン１８に挟まれ、本体ケース７に組み込まれた時、電動送風機１２、防振パッキン１８、アダプタ３０いずれの個所からも漏れが発生しないよう、アダプタ外周円３０ａの厚さはできるだけ薄くしている。 When the adapter outer peripheral circle 30a of the adapter 30 is sandwiched between the electric blower 12 and the vibration isolating packing 18 and incorporated in the main body case 7, no leakage occurs from any part of the electric blower 12, the vibration isolating packing 18, or the adapter 30. Thus, the thickness of the adapter outer circumference circle 30a is made as thin as possible.
更にアダプタ外周円３０ａの先端は傾斜状になっているほうが望ましい。またアダプタ外周円３０ａの直径は、電動送風機１２の吸引ファン部１９の直径よりも小さい構成となっており、電動送風機１２、防振パッキン１８、アダプタ３０いずれの個所からも漏れが発生しないような構成となっている。 Furthermore, it is desirable that the tip of the adapter outer circumference circle 30a is inclined. Further, the diameter of the adapter outer circumference circle 30a is smaller than the diameter of the suction fan section 19 of the electric blower 12, so that no leakage occurs from any part of the electric blower 12, the vibration-proof packing 18, and the adapter 30. It has a configuration.
アダプタ３０のアダプタ表面３０ｂの高さは、防振パッキン１８の横方向の厚みと同寸法とすることによって、防振パッキン１８近辺に発生する乱流を低減する機能をもっている。 The height of the adapter surface 30 b of the adapter 30 has the function of reducing the turbulent flow generated in the vicinity of the anti-vibration packing 18 by making the height of the adapter surface 30 b the same as the thickness of the anti-vibration packing 18.
アダプタ３０のアダプタ突出部３０ｃは、電動送風機１２の送風機突出部２３を隠すように構成され、吸引ファン部１９の表面、またはアダプタ表面３０ｂに当たってから送風機突出部２３を乗り越えて、送風機吸込口２１に流入する空気により発生する乱流を低減する機能をもっている。アダプタ表面３０ｂとアダプタ突出部３０ｃの接線は乱流が発生しないよう、流線形状とする。 The adapter protrusion 30c of the adapter 30 is configured to conceal the blower protrusion 23 of the electric blower 12, and after striking the surface of the suction fan part 19 or the adapter surface 30b, it gets over the blower protrusion 23 and enters the blower inlet 21. It has a function to reduce turbulence generated by the incoming air. The tangent line between the adapter surface 30b and the adapter protrusion 30c has a streamline shape so as not to generate turbulent flow.
アダプタ３０のアダプタ吸込口３０ｄは、気流が電動送風機１２の送風機吸込口２１に滑らかに空気が入り込むよう、送風機突出部２３の径よりも大きな径を形とった形状とする。またアダプタ吸込口３０ｄの先端は、送風機吸込口２１に剥離が発生しないよう、傾斜状になっているほうが望ましい。 The adapter suction port 30d of the adapter 30 has a shape having a diameter larger than the diameter of the blower protrusion 23 so that air can smoothly enter the blower suction port 21 of the electric blower 12. Further, it is desirable that the tip of the adapter suction port 30d is inclined so that the blower suction port 21 does not peel off.
アダプタ３０のアダプタ位置合わせ３０ｅは、電動送風機１２の送風機突出部２３とアダプタ３０の位置ずれをなくすために形成されており、組み立て性を考慮し、送風機突出部２３よりも若干大きい径で構成されている。 The adapter alignment 30e of the adapter 30 is formed to eliminate the positional deviation between the blower protrusion 23 of the electric blower 12 and the adapter 30, and is configured with a slightly larger diameter than the blower protrusion 23 in consideration of assembly. ing.
アダプタ３０と電動送風機１２の間には気密部材２５が挟まれている。気密部材２５の形状は全周から漏れの無いように円環形状であることが望ましい。また、気密部材２５の径方向の大きさは、本体組み込み時において電動送風機を軸方向から見た際に、本体ケース７の接触リブ２４と防振パッキン１８の当接部と重なるように設けられることが望ましい。これにより、掃除機本体を運転させると電動送風機１２前方に負圧がかかり、本体ケース７と電動送風機１２が引き寄せあうことで防振パッキン１８と気密部材２５が圧縮され、確実に気密を確保することができる。 An airtight member 25 is sandwiched between the adapter 30 and the electric blower 12. The shape of the airtight member 25 is preferably an annular shape so as not to leak from the entire circumference. The radial size of the airtight member 25 is provided so as to overlap the contact rib 24 of the main body case 7 and the contact portion of the vibration-proof packing 18 when the electric blower is viewed from the axial direction when the main body is assembled. It is desirable. As a result, when the cleaner body is operated, negative pressure is applied in front of the electric blower 12, and the main body case 7 and the electric blower 12 are attracted to compress the vibration-proof packing 18 and the airtight member 25 to ensure airtightness. be able to.
気密部材２５の材質は、例えば発砲ポリエチレンのような弾性体がよい。これにより、気密部材２５が部品の歪みに対して形状を合わせることができる。更に言えば、軟らかく独立気泡体であれば、より確実に気密をとることができる。 The material of the airtight member 25 is preferably an elastic body such as foamed polyethylene. Thereby, the airtight member 25 can match the shape with respect to the distortion of the component. Furthermore, if it is a soft closed cell body, it can be more reliably hermetic.
図７は気密部材２５の正面図である。なお、アダプタ３０と電動送風機の間にある気密部材２５は、円環状である。円型の抜き型で材料を抜くと中央部が無駄になってしまう。よって、図７に示すように直線状（棒状）の抜き型で抜き、棒状になった気密部材２５の両端を接着し円環状としたほうが、円形の抜き型で抜くよりも材料の使用量を減らすことができコスト低減となる。 FIG. 7 is a front view of the airtight member 25. In addition, the airtight member 25 between the adapter 30 and the electric blower has an annular shape. If the material is extracted with a circular punch, the central part will be wasted. Therefore, as shown in FIG. 7, it is more preferable to use a linear (bar-shaped) punching die and bond both ends of the rod-shaped airtight member 25 to form an annular shape, rather than using a circular punching die. The cost can be reduced.
また、気密部材２５の両端の接着面は斜めに切ってもよい。斜めに加工することで接着貼り付け面が増えて張りやすくなり接着力が増し確実に両端を貼り付けることができるためである。 Further, the adhesive surfaces at both ends of the airtight member 25 may be cut obliquely. This is because by processing at an angle, the adhesive attachment surface increases and it becomes easy to be stretched, the adhesive force is increased, and both ends can be reliably attached.
また、本実施例において気密部材２５は１つで説明したが、異なる径の気密部材を複数設けても良い。これにより更に気密を確保することができる。 In the present embodiment, the single airtight member 25 has been described. However, a plurality of airtight members having different diameters may be provided. Thereby, further airtightness can be secured.
また、本実施例において気密部材２５の形状を円環形状としたが、この限りではない。
気密を確保することができればよいため、四角環形状であっても三角環形状であってもよい。
In the present embodiment, the shape of the airtight member 25 is an annular shape, but this is not restrictive.
Since it is only necessary to ensure airtightness, it may be a quadrangular ring shape or a triangular ring shape.
