Description

本発明は、モータと該モータによって回転駆動される集塵ファンを備えたヘッド部を有底円筒状のタンクの上面開口部に着脱可能に被着して成る可搬型集塵機に関するものである。   The present invention relates to a portable dust collector in which a head portion including a motor and a dust collecting fan that is rotationally driven by the motor is detachably attached to an upper surface opening of a bottomed cylindrical tank.

この種の可搬型集塵機は、例えば図７に示すように、丸のこ盤等の電動工具３０に可撓性のダストホース４０によって接続され、電動工具３０による木材等の被切断材Ｗの切断によって発生する粉塵を吸引して回収するものであって、粉塵を溜めるタンク２と、該タンク２の上部に被着されたヘッド部３を備えている。ヘッド部３には駆動源であるモータ４等が備えられており、クランプ５を操作することによってヘッド部３はタンク２に対して容易に着脱される。   For example, as shown in FIG. 7, this type of portable dust collector is connected to an electric tool 30 such as a circular saw board by a flexible dust hose 40, and the electric tool 30 cuts a workpiece W such as wood. Is provided with a tank 2 for collecting dust and a head portion 3 attached to the upper part of the tank 2. The head unit 3 is provided with a motor 4 as a driving source, and the head unit 3 can be easily attached to and detached from the tank 2 by operating the clamp 5.

ここで、上記可搬型集塵機１’の構成の詳細を図８及び図９に基づいて説明する。   Here, details of the configuration of the portable dust collector 1 ′ will be described with reference to FIGS. 8 and 9.

図８は従来の可搬型集塵機の一部を破断して示す側断面図、図９は図８のＣ−Ｃ線断面図であり、図８に示すように、ヘッド部３の中心部に縦方向に配置された前記モータ４から垂直下方に延びる出力軸（モータ軸）６には集塵ファン７が直結されている。又、ヘッド部３には、前記モータ４を起動／停止するためのスイッチ８と空気を排出する排出口９が設けられており、ヘッド部３は、モータ４と集塵ファン７の形状により上方から見て略円形に形成され、該ヘッド部３に対応してタンク２の上方の開口部も略円形に形成されている。   FIG. 8 is a side sectional view showing a part of a conventional portable dust collector, and FIG. 9 is a sectional view taken along the line CC of FIG. 8. As shown in FIG. A dust collecting fan 7 is directly connected to an output shaft (motor shaft) 6 extending vertically downward from the motor 4 arranged in the direction. Further, the head 3 is provided with a switch 8 for starting / stopping the motor 4 and a discharge port 9 for discharging air, and the head 3 is located upward depending on the shape of the motor 4 and the dust collecting fan 7. When viewed from the top, the upper portion of the tank 2 is also formed in a substantially circular shape corresponding to the head portion 3.

他方、タンク２は下方に向かって広がる有底円筒状に成形されており、その下部には複数のキャスタ１０が取り付けられている。又、このタンク２の内部には下方に向かって絞られた漏斗状のフィルタ１１が収容されており、タンク２の側部には、図７に示す電動工具３０から延びるダクトホース４０を着脱するための吸込口１２が開口している。この吸込口１２は、図９に示すように、ダクトホース４０からタンク２内に吸引された粉塵がタンク２の内周面に沿って旋回するよう、上面視でタンクの中心に対して傾斜して設けられている。   On the other hand, the tank 2 is formed in a bottomed cylindrical shape that expands downward, and a plurality of casters 10 are attached to the lower part thereof. In addition, a funnel-shaped filter 11 squeezed downward is accommodated in the tank 2, and a duct hose 40 extending from the electric tool 30 shown in FIG. For this purpose, a suction port 12 is opened. As shown in FIG. 9, the suction port 12 is inclined with respect to the center of the tank when viewed from above so that the dust sucked into the tank 2 from the duct hose 40 turns along the inner peripheral surface of the tank 2. Is provided.

以上のように構成された可搬型集塵機１’において、スイッチ８をＯＮしてモータ４を起動すると、該モータ４の出力軸６とこれに直結された集塵ファン７が回転し、タンク２内に吸引力（負圧）が発生し、図７に示す電動工具３０による被切断材Ｗの切断によって発生する粉塵Ｐが空気と共にダクトホース４０を通って当該可搬型集塵機１’の吸込口１２からタンク２内に吸引される。   In the portable dust collector 1 ′ configured as described above, when the switch 4 is turned on to start the motor 4, the output shaft 6 of the motor 4 and the dust collecting fan 7 directly connected to the motor 4 rotate to rotate inside the tank 2. A suction force (negative pressure) is generated, and dust P generated by cutting the workpiece W by the electric tool 30 shown in FIG. 7 passes through the duct hose 40 together with air from the suction port 12 of the portable dust collector 1 ′. Sucked into the tank 2.

而して、前述のように吸込口１２は上面視でタンク２の中心に対して傾斜して設けられているため、タンク２内に空気と共に吸引された粉塵Ｐは、図８に矢印にて示すようにタンク２の内周面に沿って旋回しながら自重で落下してタンク２内の底部に溜る。そして、タンク２内の底部に落下しなかった粉塵Ｐは、フィルタ１１によって濾過されて空気と分離され、空気のみがフィルタ１１を通過して排出口９から外部へと排出され、分離された粉塵Ｐはフィルタ１１の周面に付着する。   Thus, since the suction port 12 is inclined with respect to the center of the tank 2 in a top view as described above, the dust P sucked together with the air in the tank 2 is indicated by an arrow in FIG. As shown in the figure, it falls along its inner peripheral surface while dropping by its own weight and collected at the bottom of the tank 2. And the dust P which did not fall to the bottom part in the tank 2 is filtered and separated from the air by the filter 11, and only the air passes through the filter 11 and is discharged from the discharge port 9 to the outside. P adheres to the peripheral surface of the filter 11.

以上のようにしてタンク２内の底部に溜った粉塵Ｐを廃棄するときには、クランプ５によるヘッド部３の固定を解除した後、該ヘッド部３を上方に持ち上げてタンク２から取り外し、タンク２ごと横に倒して該タンク２内の底部に溜った粉塵Ｐを廃棄する。   When discarding the dust P collected at the bottom in the tank 2 as described above, after the head 3 is fixed by the clamp 5, the head 3 is lifted upward and removed from the tank 2. The dust P accumulated on the bottom of the tank 2 is discarded.

しかしながら、図７〜図９に示した従来の可搬型集塵機１’においては、タンク２内の底部に溜った粉塵Ｐがタンク２内に生じる粉塵Ｐと空気の旋回流によって再飛散し、この再飛散した粉塵Ｐがフィルタ１１に付着するため、フィルタ１１の目詰まりが進行して吸込力が早期に低下するという問題があった。このため、吸込力回復のためにフィルタ１１を頻繁にメンテナンスしなければならず、その作業が面倒で煩雑であるという問題があった。   However, in the conventional portable dust collector 1 ′ shown in FIGS. 7 to 9, the dust P accumulated at the bottom of the tank 2 is re-scattered by the swirling flow of the dust P and air generated in the tank 2. Since the scattered dust P adheres to the filter 11, there is a problem that the filter 11 is clogged and the suction force is reduced early. For this reason, the filter 11 has to be frequently maintained in order to recover the suction force, and there is a problem that the work is troublesome and complicated.

本発明は上記問題に鑑みてなされたもので、その目的とする処は、吸込力の早期低下を防ぎ、フィルタのメンテナンスの煩雑さを低減することができる可搬型集塵機を提供することにある。   The present invention has been made in view of the above problems, and an object thereof is to provide a portable dust collector capable of preventing an early decrease in suction force and reducing complexity of filter maintenance.

上記目的を達成するため、請求項１記載の発明は、モータと該モータによって回転駆動される集塵ファンを備えたヘッド部を有底円筒状のタンクの上面開口部に着脱可能に被着し、前記タンクに、ダクトホースを着脱する吸込口を上面視で中心に対して傾斜して設けるとともに、該吸込口から空気と共に吸引された粉塵を濾過するフィルタをタンク内に収容して成る可搬型集塵機において、前記タンクの底面内周部に、径方向内方に向かって延びる衝突板を立設したことを特徴とする。   In order to achieve the above object, according to the first aspect of the present invention, a head portion including a motor and a dust collecting fan that is rotationally driven by the motor is detachably attached to an upper surface opening of a bottomed cylindrical tank. The tank is provided with a suction port for attaching and detaching the duct hose so as to be inclined with respect to the center in a top view, and a filter for filtering dust sucked together with air from the suction port is accommodated in the tank. In the dust collector, a collision plate extending inward in the radial direction is erected on the inner peripheral portion of the bottom surface of the tank.

請求項２記載の発明は、請求項１記載の発明において、前記衝突板を前記タンクの内周に沿って複数立設したことを特徴とする。   According to a second aspect of the present invention, in the first aspect of the present invention, a plurality of the collision plates are erected along the inner periphery of the tank.

請求項３記載の発明は、請求項２記載の発明において、側面積が異なる複数の衝突板を周方向に配置したことを特徴とする。   The invention according to claim 3 is the invention according to claim 2, wherein a plurality of collision plates having different side areas are arranged in the circumferential direction.

請求項４記載の発明は、請求項１〜３の何れかに記載の発明において、前記衝突板を上面視でタンク中心に対して傾斜させて配置したことを特徴とする。   According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the collision plate is arranged to be inclined with respect to the center of the tank in a top view.

請求項５記載の発明は、請求項１〜４の何れかに記載の発明において、前記衝突板を前記タンクと一体成形したことを特徴とする。   The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the collision plate is formed integrally with the tank.

請求項１及び２記載の発明によれば、タンク内に吸引された粉塵を含んだ空気の旋回流がタンクの底面内周部に立設された衝突板で止められ、タンクの底部に一旦溜った粉塵が再飛散してフィルタに付着することがないため、フィルタの目詰まりの進行が防がれて吸込力が早期に低下するという問題が解消される。従って、吸込力回復のためにフィルタを頻繁にメンテナンスする必要がなく、フィルタのメンテナンスの煩雑さを低減することができる。   According to the first and second aspects of the present invention, the swirling flow of the air containing the dust sucked into the tank is stopped by the collision plate erected on the inner periphery of the bottom surface of the tank, and is temporarily accumulated at the bottom of the tank. Therefore, the problem that the suction force is reduced early is prevented by preventing the filter from clogging. Therefore, it is not necessary to frequently maintain the filter to recover the suction force, and the complexity of the filter maintenance can be reduced.

請求項３記載の発明によれば、側面積（長さ及び高さ）が異なる複数の衝突板をタンクの底面内周部に配置したため、タンク内に生じた粉塵を含んだ空気の旋回流は段階的に衝突板に衝突してその流速が徐々に弱められるため、粉塵を含んだ空気の旋回流が各衝突板に衝突したときの局部的な粉塵の舞い上がりが防がれ、粉塵のフィルタへの付着が一層確実に防がれる。   According to the invention described in claim 3, since the plurality of collision plates having different side areas (length and height) are arranged on the inner periphery of the bottom surface of the tank, the swirling flow of the air containing dust generated in the tank is Since the collision velocity of the impingement plate is gradually reduced and the flow velocity is gradually reduced, the local dust rising when the swirling flow of air containing dust collides with each impingement plate is prevented and the dust filter is used. Is more reliably prevented.

請求項４記載の発明によれば、衝突板を上面視でタンク中心に対して傾斜させて配置したため、タンク内のフィルタを収容するためのスペースを大きくすることができる。この結果、フィルタの外周径も大きくして濾過面積を拡大することができ、フィルタが目詰まりするまでの期間を長くして吸込力の低下の進行を一層効果的に抑制することができる。   According to the fourth aspect of the present invention, since the collision plate is disposed so as to be inclined with respect to the center of the tank in a top view, a space for accommodating the filter in the tank can be increased. As a result, the outer peripheral diameter of the filter can be increased to increase the filtration area, the period until the filter is clogged can be lengthened, and the progress of the reduction in suction force can be more effectively suppressed.

請求項５記載の発明によれば、衝突板をタンクと一体成形したため、請求項１〜４記載の発明の上記効果を低コストで得ることができる。   According to invention of Claim 5, since the collision board was integrally molded with the tank, the said effect of the invention of Claims 1-4 can be acquired at low cost.

以下に本発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

＜実施の形態１＞
図１は本発明の実施の形態１に係る可搬型集塵機の一部を破断して示す側断面図、図２は図１のＡ−Ａ線断面図であり、これらの図においては図８及び図９に示したものと同一要素には同一符号を付しており、以下、これらについての再度の説明は省略する。 <Embodiment 1>
1 is a side sectional view showing a part of a portable dust collector according to Embodiment 1 of the present invention, and FIG. 2 is a sectional view taken along line AA in FIG. 1. In these figures, FIG. The same elements as those shown in FIG. 9 are denoted by the same reference numerals, and description thereof will be omitted below.

本実施の形態に係る可搬型集塵機１は、タンク２の底面内周部に、径方向内方に向かって延びるリブ状の衝突板１３を立設したことを特徴とし、他の構成は図８及び図９に示した従来の可搬型集塵機１'のそれと同じである。   The portable dust collector 1 according to the present embodiment is characterized in that a rib-shaped collision plate 13 extending inward in the radial direction is provided on the inner peripheral portion of the bottom surface of the tank 2. And it is the same as that of the conventional portable dust collector 1 'shown in FIG.

本実施の形態では、図２に示すように、タンク２の底面内周部に、タンク２の径方向に対し同じ長さの４つの衝突板１３がタンク２の中心に向かって周方向に等角度ピッチ（９０°ピッチ）でタンク２との一体成形によって立設されている。   In the present embodiment, as shown in FIG. 2, four collision plates 13 having the same length with respect to the radial direction of the tank 2 are provided on the inner peripheral portion of the bottom surface of the tank 2 in the circumferential direction toward the center of the tank 2. It is erected by integral molding with the tank 2 at an angular pitch (90 ° pitch).

而して、本実施の形態に係る可搬型集塵機１において、スイッチ８をＯＮしてモータ４を起動すると、該モータ４の出力軸６とこれに直結された集塵ファン７が回転し、タンク２内に吸引力（負圧）が発生し、例えば図７に示す電動工具３０による被切断材Ｗの切断によって発生する粉塵Ｐが空気と共にダクトホース４０を通って当該可搬型集塵機１の吸込口１２からタンク２内に吸引される。   Thus, in the portable dust collector 1 according to the present embodiment, when the switch 4 is turned on to start the motor 4, the output shaft 6 of the motor 4 and the dust collecting fan 7 directly connected thereto rotate, and the tank 2, a suction force (negative pressure) is generated, for example, dust P generated by cutting the workpiece W by the electric power tool 30 shown in FIG. 7 passes through the duct hose 40 together with air and the suction port of the portable dust collector 1 12 is sucked into the tank 2.

ここで、図２に示すように吸込口１２は上面視でタンク２の中心に対して傾斜して設けられているため、タンク２内に空気と共に吸引された粉塵Ｐは、図１に矢印にて示すようにタンク２の内周面に沿って旋回しながら自重で落下してタンク２内の底部に溜る。そして、タンク２内の底部に落下しなかった粉塵Ｐは、フィルタ１１によって濾過されて空気と分離され、空気のみがフィルタ１１を通過して排出口９から外部へと排出され、分離された粉塵Ｐはフィルタ１１の周面に付着する。   Here, as shown in FIG. 2, the suction port 12 is provided to be inclined with respect to the center of the tank 2 in a top view, so that the dust P sucked together with the air in the tank 2 is indicated by an arrow in FIG. As shown in the figure, it falls along its inner peripheral surface while dropping by its own weight and collected at the bottom of the tank 2. And the dust P which did not fall to the bottom part in the tank 2 is filtered and separated from the air by the filter 11, and only the air passes through the filter 11 and is discharged from the discharge port 9 to the outside. P adheres to the peripheral surface of the filter 11.

ところで、本実施の形態では、タンク２の底面内周部に、径方向内方に向かって延びる４つの衝突板１３を立設したため、タンク２内に吸引された粉塵Ｐを含んだ空気の旋回流がタンク２の底面内周部に立設された衝突板１３で止められ、タンク２の底部に一旦溜った粉塵Ｐが再飛散してフィルタ１１に付着することがない。このため、フィルタ１１の目詰まりの進行が防がれて吸込力が早期に低下するという問題が解消され、吸込力回復のためにフィルタ１１を頻繁にメンテナンスする必要がなく、フィルタ１１のメンテナンスの煩雑さを低減することができる。
By the way, in the present embodiment, the four collision plates 13 extending inward in the radial direction are erected on the inner peripheral portion of the bottom surface of the tank 2, so that the swirling of the air containing the dust P sucked into the tank 2 The flow is stopped by the collision plate 13 erected on the inner peripheral portion of the bottom surface of the tank 2, so that the dust P once accumulated on the bottom portion of the tank 2 does not rescatter and adhere to the filter 11. For this reason, the problem that the clogging of the filter 11 is prevented and the suction force is reduced early is eliminated, and it is not necessary to frequently maintain the filter 11 to recover the suction force. Complexity can be reduced.

又、本実施の形態では、衝突板１３をタンク２と一体成形したため、上記効果を低コストで得ることができる。尚、衝突板１３をタンク２にネジ等で固定する構成としても良い。   In this embodiment, since the collision plate 13 is integrally formed with the tank 2, the above effect can be obtained at a low cost. The collision plate 13 may be fixed to the tank 2 with screws or the like.

そして、タンク２内の底部に溜った粉塵Ｐを廃棄するときには、クランプ５によるヘッド部３の固定を解除した後、該ヘッド部３を上方に持ち上げてタンク２から取り外し、タンク２ごと横に倒して該タンク２内の底部に溜った粉塵Ｐを廃棄する。   When the dust P collected at the bottom of the tank 2 is discarded, after the head 3 is fixed by the clamp 5, the head 3 is lifted upward and removed from the tank 2, and the tank 2 is tilted sideways. The dust P collected at the bottom of the tank 2 is discarded.

尚、本実施の形態では、タンク２の底面内周部に、４つの衝突板１３を周方向に９０°ピッチで周方向に配設したが、衝突板１３の枚数に制限はなく、例えば図３に示すように８つの衝突板１３を周方向に４５°ピッチで周方向に配設しても良い。   In the present embodiment, the four collision plates 13 are disposed in the circumferential direction at a 90 ° pitch in the circumferential direction on the inner peripheral portion of the bottom surface of the tank 2, but the number of the collision plates 13 is not limited. As shown in FIG. 3, eight collision plates 13 may be arranged in the circumferential direction at a 45 ° pitch in the circumferential direction.

＜実施の形態２＞
次に、本発明の実施の形態２を図４に基づいて説明する。 <Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIG.

図４は本発明の実施の形態２に係る可搬型集塵機のタンクの平断面図であり、本図においては図２及び図３に示したものと同一要素には同一符号を付し、以下、それらについての説明は省略する。   FIG. 4 is a plan sectional view of the tank of the portable dust collector according to the second embodiment of the present invention. In this figure, the same elements as those shown in FIGS. The description about them is omitted.

本実施の形態は、タンク２の底面内周部に、４つの衝突板１３を上面視でタンク２の中心に対して傾斜させて周方向に９０°ピッチで周方向に配設したことを特徴としており、他の構成は前記実施の形態１のそれと同様である。   The present embodiment is characterized in that four collision plates 13 are inclined with respect to the center of the tank 2 in a top view and disposed in the circumferential direction at a 90 ° pitch in the circumferential direction on the inner peripheral portion of the bottom surface of the tank 2. Other configurations are the same as those of the first embodiment.

而して、本実施の形態によれば、４つの衝突板１３を上面視でタンク２の中心に対して傾斜させて配置したため、タンク２内のフィルタ１１を収容するためのスペースを大きくすることができる。この結果、フィルタ１１の外周径も大きくして濾過面積を拡大することができ、フィルタ１１が目詰まりするまでの期間を長くして吸込力の低下の進行を一層効果的に抑制することができる。又、衝突板１３を傾斜させて配設しているため、該衝突板１３で止められた粉塵Ｐが衝突板１３の端面部を通過する旋回流により再飛散することが一層効果的に防がれる。   Thus, according to the present embodiment, since the four collision plates 13 are disposed to be inclined with respect to the center of the tank 2 in a top view, the space for accommodating the filter 11 in the tank 2 is increased. Can do. As a result, the outer peripheral diameter of the filter 11 can also be increased to increase the filtration area, the period until the filter 11 is clogged can be lengthened, and the progress of the reduction of the suction force can be more effectively suppressed. . Further, since the collision plate 13 is disposed at an inclination, it is more effectively prevented that the dust P stopped by the collision plate 13 is re-scattered by the swirl flow passing through the end surface portion of the collision plate 13. It is.

又、本実施の形態においても、衝突板１３をタンク２と一体成形したため、上記効果を低コストで得ることができる。   Also in the present embodiment, since the collision plate 13 is integrally formed with the tank 2, the above effect can be obtained at a low cost.

＜実施の形態３＞
次に、本発明の実施の形態３を図５及び図６に基づいて説明する。 <Embodiment 3>
Next, a third embodiment of the present invention will be described with reference to FIGS.

図５は本発明の実施の形態３に係る可搬型集塵機の一部を破断して示す側断面図、図６は図５のＢ−Ｂ線断面図であり、これらの図においては図１〜図３に示したものと同一要素には同一符号を付しており、以下、これらについての再度の説明は省略する。   5 is a side sectional view showing a part of a portable dust collector according to Embodiment 3 of the present invention, and FIG. 6 is a sectional view taken along line BB in FIG. The same elements as those shown in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted below.

本実施の形態は、側面積（長さ及び高さ）が異なる４つの衝突板１３ａ，１３ｂ，１３ｃ，１３ｄをタンク２の底面内周部に周方向に等角度ピッチ（９０°ピッチ）で配置したことを特徴としており、他の構成は実施の形態１，２のそれと同じである。   In the present embodiment, four collision plates 13a, 13b, 13c, and 13d having different side areas (length and height) are arranged on the inner peripheral portion of the bottom surface of the tank 2 at an equiangular pitch (90 ° pitch) in the circumferential direction. The other features are the same as those of the first and second embodiments.

而して、本実施の形態によれば、タンク２内に生じた粉塵Ｐを含んだ空気の旋回流は段階的に衝突板１３ａ〜１３ｄに衝突してその流速が徐々に弱められるため、粉塵Ｐを含んだ空気の旋回流が各衝突板１３ａ〜１３ｄに衝突したときの局部的な粉塵Ｐの舞い上がりが防がれ、粉塵Ｐのフィルタ１１への付着が一層確実に防がれという効果が得られる。   Thus, according to the present embodiment, the swirling flow of the air containing the dust P generated in the tank 2 collides with the collision plates 13a to 13d step by step and the flow velocity is gradually reduced. When the swirling flow of air containing P collides with the respective collision plates 13a to 13d, the local dust P is prevented from rising, and the dust P is prevented from adhering to the filter 11 more reliably. can get.

又、本実施の形態においても、衝突板１３ａ〜１３ｄをタンク２と一体成形したため、上記効果を低コストで得ることができる。   Also in the present embodiment, since the collision plates 13a to 13d are integrally formed with the tank 2, the above effects can be obtained at a low cost.

尚、本実施の形態では、４つの衝突板１３ａ〜１３ｄを周方向に９０°ピッチで周方向に配設したが、衝突板の枚数に制限はなく、又、実施の形態２のように衝突板１３ａ〜１３ｄを上面視でタンク２の中心に対して傾斜させて配置しても良い。   In the present embodiment, the four collision plates 13a to 13d are arranged in the circumferential direction at a pitch of 90 ° in the circumferential direction.
