Description

本発明は、集塵機等に用いられ、吸引した空気から塵埃を分離するサイクロン装置に関する。   The present invention relates to a cyclone device that is used in a dust collector or the like and separates dust from sucked air.

集塵機や掃除機等においては、フィルタを用いず、ハウジング内に吸引した空気を旋回させながら塵埃を分離するサイクロン方式がよく採用されている。例えば特許文献１には、接線方向の吸引路を備えて下端に集塵室を設けた外方サイクロンの内部に、下端を集塵室上に開口した内方サイクロンを設けて、外方サイクロンでの空気の旋回で大きい塵埃を分離させ、内方サイクロンでの空気の旋回で小さい塵埃を分離させるようにした二重サイクロン装置の発明が記載されている。   In a dust collector, a vacuum cleaner, or the like, a cyclone system that separates dust while swirling air sucked into a housing without using a filter is often employed. For example, in Patent Document 1, an outer cyclone having a suction path in a tangential direction and having a dust collection chamber at the lower end is provided with an inner cyclone having a lower end opened on the dust collection chamber. The invention of a double cyclone device is described in which large dust is separated by the swirling of air and small dust is separated by swirling of air by an inner cyclone.

特公昭５７−１１７０６号公報Japanese Patent Publication No.57-11706

しかし、従来のサイクロン装置では、外方サイクロンの旋回流路と内方サイクロンの旋回流路とが直列に繋がっているため、旋回流路が全体に長くなって径方向に大型化する。また、大きさに関わらず塵埃は一つの集塵室に回収されるため、旋回する空気量が多くなると小さい塵埃が舞い上がり、空気と共に装置外へ排出されてしまうおそれも生じる。   However, in the conventional cyclone device, since the swirl flow path of the outer cyclone and the swirl flow path of the inner cyclone are connected in series, the swirl flow path becomes longer as a whole and becomes larger in the radial direction. Further, since dust is collected in one dust collection chamber regardless of the size, if the amount of air swirling increases, there is a possibility that small dust will rise and be discharged out of the apparatus together with air.

そこで、本発明は、コンパクトに形成でき、塵埃の舞い上がりも生じさせずに塵埃を確実に分離回収できるサイクロン装置を提供することを目的としたものである。   Accordingly, an object of the present invention is to provide a cyclone device that can be compactly formed and can reliably separate and collect dust without causing dust to rise.

After four rounds of circulation, an introduction path 34 is formed in which the end is bent toward the center and connected to the guide path 20. A spiral upper cover 35 is screwed from the upper part of the introduction path 34 to the upper part of the guide path 20 and the sub cyclone 5 to close the upper part of the introduction path 34, the guide path 20 and the sub cyclone 5.

副サイクロン５は、図１２，１３に示すように、中上筒１６の大径部２９に嵌合するリング状の外枠４０を有し、その外枠４０の外側に、大径部２９の切欠き３８に嵌合して誘導路２０の上方に位置し、導入路３４の上側でその終端と結合される一対の平行な第１、第２導入板４１，４２を突設している。また、外枠４０の内側には、第１導入板４１と連続する第１直線壁４４と、その第１直線壁４４から外枠４０に沿って渦巻き状に周回する壁体としての第１渦巻壁４５とからなる帯板状の第１ガイド部４３が設けられている。また、第１ガイド部４３の内側には、第１導入板４１と第２導入板４２との間で第１直線壁４４と平行な第２直線壁４７と、その第２直線壁４７から第１ガイド部４３に沿って渦巻き状に周回する第２渦巻壁４８とからなる帯板状の第２ガイド部４６が設けられている。   As shown in FIGS. 12 and 13, the secondary cyclone 5 has a ring-shaped outer frame 40 that fits into the large-diameter portion 29 of the middle upper cylinder 16, and the large-diameter portion 29 is disposed outside the outer frame 40.

A strip-shaped second guide portion 46 including a second spiral wall 48 that spirally circulates along the one guide portion 43 is provided.

さらに、第２ガイド部４６の内側には、第２導入板４２と連続すると共に、第１ガイド部４３の第１渦巻壁４５の終端が接続される第３直線壁５０と、その第３直線壁５０から第２ガイド部４６に沿って渦巻き状に周回する第３渦巻壁５１とからなる帯板状の第３ガイド部４９が設けられている。この第３ガイド部４９の第３渦巻壁５１の終端と、第２ガイド部４６の第２渦巻壁４８の終端とが接続されて、第１ガイド部４３と第２ガイド部４６との間に、外枠４０の中央で第３ガイド部４９によって囲まれる貫通孔５２と連通する渦巻き状の通気路５３が形成されている。この通気路５３の下部は、第１、第２ガイド部４３，４６の下端間を閉塞する仕切板５４で閉塞される一方、外枠４０には、通気路５３を第１、第２導入板４１，４２の間、すなわち導入路３４と連通させる開口５５が形成されている。   Further, a third straight wall 50 that is continuous with the second introduction plate 42 and connected to the terminal end of the first spiral wall 45 of the first guide portion 43 and the third straight line are provided inside the second guide portion 46. A strip-shaped third guide portion 49 including a third spiral wall 51 that spirally circulates along the second guide portion 46 from the wall 50 is provided. The terminal of the third spiral wall 51 of the third guide part 49 and the terminal of the second spiral wall 48 of the second guide part 46 are connected, and the first guide part 43 and the second guide part 46 are connected. A spiral air passage 53 communicating with the through hole 52 surrounded by the third guide portion 49 is formed at the center of the outer frame 40. The lower portion of the air passage 53 is closed by a partition plate 54 that closes the lower ends of the first and second guide portions 43 and 46, while the air passage 53 is connected to the outer frame 40 by the first and second introduction plates. 41, 42, that is, an opening 55 communicating with the introduction path 34 is formed.

５６，５６・・は、外枠４０と第１ガイド部４３の第１渦巻壁４５との間で、放射方向から第１渦巻壁４５に沿った傾斜方向に架設され、第１ガイド部４３を支持する外支持板、５７，５７・・は、第２ガイド部４６と第３ガイド部４９との間で外支持板５６と同じ傾斜方向に架設される内支持板で、第１ガイド部４３の第１渦巻壁４５と第３ガイド部４９の第３渦巻壁５１とには、両支持板５６，５７と同じ傾斜方向に貫通する透孔５８，５８・・が、所定間隔をおいて複数形成されて、通気路５３を外枠４０と第１ガイド部４３との間に、貫通孔５２を第２ガイド部４６と第３ガイド部４９との間にそれぞれ連通させている。   56, 56... Are installed between the outer frame 40 and the first spiral wall 45 of the first guide part 43 in an inclined direction along the first spiral wall 45 from the radial direction. The outer support plates 57, 57,... Are inner support plates that are installed between the second guide portion 46 and the third guide portion 49 in the same inclination direction as the outer support plate 56, and the first guide portion 43. The first spiral wall 45 and the third spiral wall 51 of the third guide portion 49 have a plurality of through holes 58, 58,. The air passage 53 is formed between the outer frame 40 and the first guide portion 43, and the through hole 52 is communicated between the second guide portion 46 and the third guide portion 49.

また、第３ガイド部４９の下端には、図１４にも示すように、貫通孔５２から下方へ行くに従って拡径するテーパ筒状のキャップ部５９が一体に形成されている。このキャップ部５９は、中ハウジング１４の中上筒１６の小径部１８に嵌合して小径部１８を閉塞するもので、キャップ部５９の上面と第１、第２ガイド部４３，４６の下面との間には、内支持板５７と連続状の傾斜リブ６０，６０・・が立設されて、第１、第２ガイド部４３，４６とキャップ部５９との間に、全周に亘って隙間を形成している。   Further, as shown in FIG. 14, a tapered cylindrical cap portion 59 whose diameter increases as it goes downward from the through hole 52 is integrally formed at the lower end of the third guide portion 49. The cap portion 59 is fitted to the small diameter portion 18 of the middle upper cylinder 16 of the middle housing 14 and closes the small diameter portion 18. The upper surface of the cap portion 59 and the lower surfaces of the first and second guide portions 43 and 46. Between the first and second guide portions 43, 46 and the cap portion 59, and the inner support plate 57 and the continuous inclined ribs 60, 60,. A gap is formed.

よって、副サイクロン５を、外枠４０を大径部２９に、キャップ部５９を小径部１８にそれぞれ嵌合させた状態では、通気路５３は、第１ガイド部４３の透孔５８，５８・・を介して副集塵室３０と連通すると共に、貫通孔５２は、第３ガイド部４９の透孔５８，５８・・を介して副集塵室３０と連通することになる。
また、上カバー３５によって通気路５３を含む外枠４０の上端が閉塞されることで、主吸引路３７の途中に、図５，１１にも示すように、上側の開口５５から副サイクロン５内に進入し、第１直線壁４４と第２直線壁４７との間を通る副吸引路６１と、副吸引路６１が接線方向に連通して第１渦巻壁４５と第２渦巻壁４８との間で外枠４０内を旋回して貫通孔５２に至る副旋回室６２とが形成される。すなわち、主吸引路３７は、誘導路２０を介して副サイクロン５の下側を潜って主旋回室２３側へ導かれる一方、副吸引路６１は、主吸引路３７から誘導路２０の上側に分岐して副サイクロン５内に導かれて形成されることになる。 Therefore, in the state in which the sub cyclone 5 is fitted to the outer frame 40 in the large diameter portion 29 and the cap portion 59 in the small diameter portion 18, the ventilation path 53 is formed in the through holes 58, 58. The through hole 52 communicates with the sub dust collection chamber 30 through the through holes 58, 58,... Of the third guide portion 49.
Further, the upper cover 35 closes the upper end of the outer frame 40 including the ventilation path 53, so that the upper suction opening 37 is inserted into the sub cyclone 5 from the upper opening 55 as shown in FIGS. , The sub suction path 61 passing between the first straight wall 44 and the second straight wall 47, and the sub suction path 61 communicates in a tangential direction between the first spiral wall 45 and the second spiral wall 48. A sub swirl chamber 62 that swirls within the outer frame 40 and reaches the through hole 52 is formed. That is, the main suction path 37 is guided to the main swirl chamber 23 side through the lower side of the sub cyclone 5 via the guide path 20, while the sub suction path 61 is extended from the main suction path 37 to the upper side of the guide path 20. It branches and is led and formed in the auxiliary cyclone 5.

一方、排気筒３は、上カバー３５の上面に外枠４０と同心円上にネジ止めされている。排気筒３内には、図４及び図１５〜１７に示すように、排気筒３内に嵌入され、排気筒３の上端から上カバー３５を貫通して貫通孔５２に達する外筒６３と、その外筒６３の内側で放射方向の小リブ６４，６４・・によって隙間をおいて保持され、排気筒３の上端から上カバー３５を貫通してその下方へ突出する内筒６５とが設けられている。内筒６５において、副サイクロン５の貫通孔５２を貫通する下方部６６は、上側部分よりも大径となって、その上端に形成したフランジ６７が貫通孔５２の下端に嵌合して貫通孔５２を閉塞し、そのままキャップ部５９を貫通して内ハウジング６の内上筒８内へ同軸で突出している。この状態で下方部６６の下端は、内上筒８のスリット１３の下端と略同じ高さとなっている。よって、ここでは、内筒６５が、主旋回室２３の上部と上下方向に連通してその内部に主排出路６８を形成し、外筒６３と内筒６５との間の隙間が、副旋回室６２の終端となる貫通孔５２と上下方向に連通して副排出路６９を形成することになる。   On the other hand, the exhaust tube 3 is screwed to the upper surface of the upper cover 35 concentrically with the outer frame 40. As shown in FIGS. 4 and 15 to 17, an outer cylinder 63 that is fitted in the exhaust cylinder 3 and penetrates the upper cover 35 from the upper end of the exhaust cylinder 3 to reach the through hole 52, Inside the outer cylinder 63, there is provided an inner cylinder 65 which is held with a gap by radial radial ribs 64, 64... And passes through the upper cover 35 from the upper end of the exhaust cylinder 3 and projects downward. ing. In the inner cylinder 65, the lower part 66 that penetrates the through hole 52 of the sub-cyclone 5 has a larger diameter than the upper part, and a flange 67 formed at the upper end of the inner cylinder 65 is fitted to the lower end of the through hole 52, 52 is closed, passes through the cap portion 59 as it is, and projects coaxially into the inner upper cylinder 8 of the inner housing 6. In this state, the lower end of the lower portion 66 has substantially the same height as the lower end of the slit 13 of the inner upper cylinder 8. Therefore, here, the inner cylinder 65 communicates with the upper part of the main swirl chamber 23 in the vertical direction to form the main discharge path 68 therein, and the gap between the outer cylinder 63 and the inner cylinder 65 is a sub swirl. The sub-discharge path 69 is formed in communication with the through-hole 52 serving as the terminal end of the chamber 62 in the vertical direction.

以上の如く構成されたサイクロン装置１においては、排気筒３に例えば電動送風機を接続する一方、吸込口３６にホース等を接続すると、塵埃と共に空気を吸引することができる。吸引された空気は、導入路３４から誘導路２０に至ってその上下に分岐し、一方が下側の主吸引路３７に、他方が上側の副吸引路６１にそれぞれ流れることになるが、風量は下側の誘導路２０の方が大きくなる。ここで、比較的大きな塵埃は、導入路３４の下側を専ら移動するため、殆どが主吸引路３７から主旋回室２３内に進入し、図４に実線矢印で示すようにそのまま落下して内下筒７内の主集塵室１１に貯留する。このとき、主集塵室１１に落下しない中程度の塵埃は、図４及び６に点線矢印で示すように主旋回室２３内を空気が旋回する際の遠心力により、スリット１３，１３・・を介して実線矢印のように外側集塵室２４内に落下して貯留する。主旋回室２３を旋回した空気は、内筒６５内の主排出路６８を通って上方に排出される。   In the cyclone device 1 configured as described above, for example, when an electric blower is connected to the exhaust tube 3 and a hose or the like is connected to the suction port 36, air can be sucked together with dust. The sucked air reaches the guide path 20 from the introduction path 34 and branches up and down. One of the air flows into the lower main suction path 37 and the other flows into the upper sub suction path 61. The lower taxiway 20 is larger. Here, since relatively large dust moves exclusively under the introduction path 34, most of the dust enters the main swirl chamber 23 from the main suction path 37 and falls as it is as shown by solid line arrows in FIG. 4. It is stored in the main dust collection chamber 11 in the inner and lower cylinders 7. At this time, medium dust that does not fall into the main dust collection chamber 11 is slit 13, 13... By centrifugal force when air swirls in the main swirl chamber 23 as shown by dotted arrows in FIGS. Through the outer dust collecting chamber 24 as indicated by a solid line arrow. The air swirled in the main swirl chamber 23 is discharged upward through the main discharge passage 68 in the inner cylinder 65.

一方、主吸引路３７に流れない細かい塵埃は、図１１に一点鎖線矢印で示すように上側の副吸引路６１を流れて副旋回室６２を旋回する。第１渦巻壁４５には透孔５８，５８・・が形成されているため、細かい塵埃は、第１渦巻壁４５に沿って空気が旋回する際の遠心力により、図４及び１４に実線矢印で示すように、透孔５８，５８・・を介して外枠４０との間に排出され、そのまま副集塵室３０内に落下して貯留する。ここで分離されずに貫通孔５２に達した細かい塵埃は、第３渦巻壁５１に沿って空気が旋回する際の遠心力により、透孔５８，５８・・を介して第２渦巻壁４８との間に排出され、そのまま副集塵室３０内に落下して貯留する。副旋回室６２を旋回した空気は、外筒６３と内筒６５との間の副排出路６９を通って上方に排出される。
こうして各集塵室１１，２４，３０に貯留された塵埃を排出する際には、蓋体３１を取り外せば、各集塵室１１，２４，３０の下端が同時に開放されるため、サイクロン装置１の下端から塵埃を一度に排出することができる。 On the other hand, the fine dust that does not flow into the main suction path 37 flows through the upper sub suction path 61 as shown by a one-dot chain line arrow in FIG. Since the first spiral wall 45 has through-holes 58, 58,..., Fine dust is caused by centrifugal force when air swirls along the first spiral wall 45, and solid arrows in FIGS. As shown in FIG. 5, the gas is discharged between the outer frame 40 through the through holes 58, 58,. The fine dust that has reached the through hole 52 without being separated here is separated from the second spiral wall 48 via the through holes 58, 58... By centrifugal force when the air swirls along the third spiral wall 51. And is dropped and stored in the sub-dust collection chamber 30 as it is. The air swirled in the sub swirl chamber 62 is discharged upward through a sub discharge path 69 between the outer cylinder 63 and the inner cylinder 65.
Thus, when discharging the dust stored in each of the dust collection chambers 11, 24, 30, if the lid 31 is removed, the lower ends of the dust collection chambers 11, 24, 30 are simultaneously opened, so the cyclone device 1 Dust can be discharged at one time from the lower end of the.

このように、上記形態のサイクロン装置１は、下部に主集塵室１１を有する主旋回室２３と、主旋回室２３へその接線方向に連通する主吸引路３７と、主旋回室２３の上部へ上下方向に連通する主排出路６８とを備え、主吸引路３７から主旋回室２３に流入した空気が主旋回室２３を旋回して主排出路６８から排出されることで、塵埃を遠心分離して主集塵室１１に貯留させる主サイクロン４と、主吸引路３７から上方に分岐し、主吸引路３７へ吸引される塵埃よりも小さい塵埃が吸引される副吸引路６１と、主旋回室２３の上側に配置されて副吸引路６１が接線方向に連通する副旋回室６２と、その副旋回室６２の上部へ上下方向に連通する副排出路６９と、副旋回室６２の下部に連通し、主集塵室１１と区画される副集塵室３０とを備え、副吸引路６１から副旋回室６２に流入した空気が副旋回室６２を旋回して副排出路６９から排出されることで、塵埃を遠心分離して副集塵室３０に集塵させる副サイクロン５と、を含んでなる構成としている。
これにより、径方向の寸法が小さくなって全体をコンパクトに形成することができる。また、大きさが異なる塵埃を主集塵室１１と副集塵室３０とにそれぞれ分別して回収できるため、塵埃の舞い上がりを生じさせることがなく、好適な集塵効率が維持可能となる。 Thus, the cyclone apparatus 1 of the said form is the main swirl chamber 23 which has the main dust collection chamber 11 in the lower part, the main suction path 37 connected to the main swirl chamber 23 in the tangential direction, and the upper part of the main swirl chamber 23 And a main discharge passage 68 communicating in the vertical direction with the air, and the air flowing into the main swirl chamber 23 from the main suction passage 37 swirls around the main swirl chamber 23 and is discharged from the main discharge passage 68, whereby the dust is centrifuged. A main cyclone 4 that is separated and stored in the main dust collecting chamber 11; a sub-suction passage 61 that branches upward from the main suction passage 37 and sucks dust smaller than dust sucked into the main suction passage 37; A sub-swirl chamber 62 that is disposed above the swirl chamber 23 and communicates with the sub-suction passage 61 in the tangential direction, a sub-discharge passage 69 that communicates with the upper part of the sub-swirl chamber 62 in the vertical direction, and a lower portion of the sub-swirl chamber 62 A main dust collecting chamber 11 and a sub dust collecting chamber 30 which is partitioned. The sub cyclone in which the air flowing into the sub swirl chamber 62 from the sub suction passage 61 swirls in the sub swirl chamber 62 and is discharged from the sub discharge passage 69 to centrifuge the dust and collect the dust in the sub dust collection chamber 30. 5.
Thereby, the dimension of radial direction becomes small and the whole can be formed compactly. Further, since dusts having different sizes can be separately collected in the main dust collection chamber 11 and the sub dust collection chamber 30, the dust does not rise, and a suitable dust collection efficiency can be maintained.

特にここでは、主旋回室２３の外側に、スリット１３を介して主旋回室２３と連通し、主集塵室１１及び副集塵室３０と区画される外側集塵室２４を形成して、主旋回室２３を旋回する空気の遠心力により、主集塵室１１に落下しない塵埃をスリット１３を介して外側集塵室２４に貯留させるようにしているので、主集塵室１１と副集塵室３０とに貯留されない中程度の塵埃も分離して貯留することができる。
また、副旋回室６２を、外周側が副集塵室３０と連通する渦巻き状の通気路５３を含むものとし、通気路５３を形成する外周側の第１渦巻壁４５に、通気路５３を通過する空気の遠心力により、塵埃を通気路５３の外周側へ排出する透孔５８，５８・・を形成したことで、副旋回室６２内を旋回する空気から透孔５８を介して塵埃を効率良く分離することができる。 In particular, an outer dust collection chamber 24 that communicates with the main swirl chamber 23 through the slit 13 and is partitioned from the main dust collection chamber 11 and the sub dust collection chamber 30 is formed outside the main swirl chamber 23. Dust that does not fall into the main dust collection chamber 11 is stored in the outer dust collection chamber 24 through the slit 13 by the centrifugal force of the air swirling in the main swirl chamber 23. Intermediate dust that is not stored in the dust chamber 30 can also be stored separately.
The auxiliary swirl chamber 62 includes a spiral air passage 53 whose outer peripheral side communicates with the sub dust collection chamber 30, and passes through the air passage 53 to the first spiral wall 45 on the outer peripheral side forming the air passage 53. By forming the through holes 58, 58,... For discharging the dust to the outer peripheral side of the air passage 53 by the centrifugal force of the air, the dust is efficiently discharged from the air swirling in the auxiliary swirl chamber 62 through the through hole 58. Can be separated.

さらに、各集塵室１１，２４，３０を、底部に設けた一つの蓋体３１で同時に開閉可能としているので、塵埃を異なる集塵室に分離回収しても容易に廃棄できる。
加えて、主吸引路３７内をその途中で上下に分割して上側を副吸引路６１としたことで、主吸引路３７から上方へ分岐する副吸引路６１を上下方向へコンパクトに形成することができる。 Furthermore, since each dust collection chamber 11, 24, 30 can be opened and closed simultaneously by a single lid 31 provided at the bottom, it can be easily discarded even if dust is separated and collected in different dust collection chambers.
In addition, by dividing the inside of the main suction path 37 vertically in the middle and forming the upper suction path 61 as the upper suction path 61, the sub suction path 61 branching upward from the main suction path 37 can be compactly formed in the vertical direction. Can do.

なお、上記形態では、内ハウジングの外側に中ハウジングを設けて外側集塵室を形成し、スリットを介して中程度の塵埃を外側集塵室に貯留させるようにしているが、中ハウジング及びスリットを省略して主集塵室に大中の塵埃を貯留させるようにしてもよい。
また、一つの蓋体で全ての集塵室を同時に開閉可能としているが、集塵室毎に異なる蓋体で開閉可能として、大きさ別に塵埃を廃棄可能とすることもできる。さらには蓋体をヒンジ構造で開閉可能としたり、蓋体にキャスターを設けて装置を可動式にしたりすることも考えられる。
そして、各ハウジングは、上下２つの筒体で形成する構造に限らず、３つ以上の筒体で形成してもよいし、逆に１つの筒体で形成してもよい。各ハウジングの深さや外径も適宜変更できる。 In the above embodiment, the outer housing is provided outside the inner housing to form the outer dust collecting chamber, and medium dust is stored in the outer dust collecting chamber through the slit. May be omitted and large and middle dust may be stored in the main dust collection chamber.
Moreover, although all the dust collection chambers can be opened and closed simultaneously with one lid, it is possible to open and close with different lids for each dust collection chamber so that dust can be discarded according to size.
