A direction perpendicular to the horizontal plane is defined as a height direction. Moreover, let the opposite side to the drive device 200 in the dust collector 100 be a front side, and let the opposite side to this front side be a rear side.
　また、駆動装置２００には、電動送風機２２０（図３参照）、制御装置（不図示）などが内蔵されている。電動送風機２２０は、吸気を行うための送風ファン及び該送風ファンを回転駆動する送風駆動モータを有している。また、上記制御装置は、ＣＰＵやＲＡＭ，ＲＯＭなどの制御機器を有しており、電気掃除機を統括的に制御する。具体的には、上記制御装置では，ＣＰＵがＲＯＭに記憶された制御プログラムに従って各種の処理を実行する。 Also, the drive device 200 incorporates an electric blower 220 (see FIG. 3), a control device (not shown), and the like.

　（電気掃除機の動作）
　本実施形態に係る電気掃除機の動作について、以下に説明する。まず、電気掃除機を操作すると、駆動装置２００の制御装置は、電動送風機を作動させ、吸気口部２から吸気する。吸気口部２から吸気された空気は、接続管３及び接続ホース４を通じ、接続ホース４に接続された接続部２０１を介して掃除機本体１に流入する。掃除機本体１を流入した塵埃含有空気は、集塵装置１００に流入する。集塵装置１００の流入口１１３に流入した塵埃含有空気は、図４及び図５の（ｂ）の矢印で示す分離経路Ｘを経由して、上部カバーユニット１３０を通過し、集塵装置１００から排出し、駆動装置２００の電動送風機へ吸引される。 (Operation of vacuum cleaner)
The operation of the vacuum cleaner according to this embodiment will be described below. First, when the electric vacuum cleaner is operated, the control device of the driving device 200 operates the electric blower and sucks air from the air inlet portion 2. The air sucked from the air inlet 2 flows into the cleaner body 1 through the connecting pipe 3 and the connecting hose 4 and through the connecting part 201 connected to the connecting hose 4. The dust-containing air that has flowed into the cleaner body 1 flows into the dust collector 100. The dust-containing air that has flowed into the inlet 113 of the dust collector 100 passes through the upper cover unit 130 via the separation path X indicated by the arrows in FIGS. It is discharged and sucked into the electric blower of the driving device 200.
　集塵装置１００では、集塵カップ１１１内のダスト仕切部１２４の上部にあるフランジ部１２４ａを境に、上部が第１遠心分離部７０（サイクロン部）として作用する。すなわち、集塵装置１００において、第１遠心分離部７０（第１の遠心分離部）は、集塵カップ１１１の内側面、及び内筒部１２３の外周面等によって構成された旋回風路であり、少なくとも内筒部１２３を備えている。そして、流入口１１３は、第１遠心分離部７０が構成する旋回風路の接線方向に開口している。それゆえ、流入口１１３を介して流入した塵埃含有空気は、図４の分離経路Ｘのように、第１遠心分離部７０が構成する旋回風路を旋回することによって、該塵埃含有空気中の塵埃が遠心分離される。遠心分離された塵埃のうち、比較的大きい粗塵（第１の塵埃）は、遠心力の作用により、集塵カップ１１１の内側面に沿って落下して、ダスト仕切部１２４の下方に集積される。 In the dust collector 100, the upper part acts as a first centrifugal separator 70 (cyclone part) with the flange part 124a at the upper part of the dust partition part 124 in the dust collecting cup 111 as a boundary. That is, in the dust collector 100, the first centrifugal separation unit 70 (first centrifugal separation unit) is a swirling air passage constituted by the inner surface of the dust collection cup 111, the outer peripheral surface of the inner cylindrical portion 123, and the like. At least the inner cylinder portion 123 is provided. The inflow port 113 opens in the tangential direction of the swirling air passage formed by the first centrifugal separator 70. Therefore, the dust-containing air that has flowed in through the inflow port 113 swirls in the swirl air passage formed by the first centrifugal separator 70 as in the separation path X of FIG. Dust is centrifuged. Among the dust that has been centrifuged, relatively large coarse dust (first dust) falls along the inner surface of the dust collection cup 111 due to the action of centrifugal force and is accumulated below the dust partition 124. The
　粗塵が分離された空気は、内筒部１２３を通過する（図４の分離経路Ｘ参照）。このとき、第１遠心分離部７０によって分離されなかった比較的小さい細塵（第２の塵埃）は、空気流とともに、内筒部１２３のスリット１２３ｂを介して上昇する。一方、粗塵は、胴部１２３ｃに巻き付けられたメッシュ状のフィルタによって濾過される。内筒部１２３を通過した空気は、上蓋本体１２１の連通穴１２１ｄを通過し、上蓋本体１２１の分岐空間部１２１ｅに到達する。そして、分岐空間部１２１ｅから，流入口８１を介して、第２遠心分離部８０へ流入する。 The air from which the coarse dust has been separated passes through the inner cylinder portion 123 (see the separation path X in FIG. 4). At this time, the relatively small fine dust (second dust) that has not been separated by the first centrifugal separator 70 rises along with the air flow through the slit 123b of the inner cylinder 123. On the other hand, the coarse dust is filtered by a mesh filter wound around the trunk portion 123c. The air that has passed through the inner cylinder portion 123 passes through the communication hole 121 d of the upper lid body 121 and reaches the branch space portion 121 e of the upper lid body 121. And it flows in into the 2nd centrifugation part 80 through the inflow port 81 from the branch space part 121e.
　第２遠心分離部８０において、塵埃含有空気が流入する流入口８１は、旋回筒部８２と排気筒８３との間に形成された空気の旋回流路の接線方向に開口している。それゆえ、流入口８１から流入した塵埃含有空気は、図５の（ｂ）に示された分離経路Ｘのように、旋回筒部８２の内周面に沿って旋回する。第２遠心分離部８０は、塵埃含有空気の旋回半径が第１遠心分離部７０での旋回半径よりも小さく、かつ、旋回速度が第１遠心分離部７０での旋回速度よりも大きくなるように設計されている。これにより、第１遠心分離部７０を通過した塵埃含有空気について、第１遠心分離部７０によって分離された粗塵よりも小さい塵埃、すなわち細塵を分離することができる。それゆえ、第２遠心分離部８０での空気の旋回によって、塵埃含有空気中の細塵（第２の塵埃）は、遠心分離され、旋回筒部８２の内周面に沿って落下し、排出口８２ａから集塵カップ１１１へ入り、最終的に、集塵カップ１１１の底蓋１１４上に溜められる。 In the second centrifugal separator 80, the inflow port 81 into which dust-containing air flows is opened in the tangential direction of the swirl flow path of air formed between the swirl tube portion 82 and the exhaust tube 83. Therefore, the dust-containing air that has flowed in from the inflow port 81 swirls along the inner peripheral surface of the swirl tube portion 82 as in the separation path X shown in FIG. The second centrifugal separator 80 is configured so that the turning radius of the dust-containing air is smaller than the turning radius in the first centrifugal separator 70 and the turning speed is higher than the turning speed in the first centrifugal separator 70. Designed. Thereby, with respect to the dust-containing air that has passed through the first centrifugal separator 70, dust that is smaller than the coarse dust separated by the first centrifugal separator 70, that is, fine dust, can be separated. Therefore, fine dust (second dust) in the dust-containing air is centrifuged by the swirling of the air in the second centrifugal separator 80, falls along the inner peripheral surface of the swivel cylinder portion 82, and is discharged. The dust enters the dust collecting cup 111 from the outlet 82a and is finally stored on the bottom lid 114 of the dust collecting cup 111.
　そして、細塵（第２の塵埃）が分離された空気は、第２遠心分離部８０それぞれの中央部に設けられた排気筒８３を通過し、流出口８３ａから排出される（図５の（ｂ）の分離経路Ｘ参照）。流出口８３ａから排出された空気は、上部カバーユニット１３０を通過し、集塵装置１００から排出される（図４の分離経路Ｘ参照）。 Then, the air from which the fine dust (second dust) has been separated passes through the exhaust pipe 83 provided at the center of each of the second centrifugal separators 80 and is discharged from the outlet 83a ((( (See separation path X in b)). The air discharged from the outlet 83a passes through the upper cover unit 130 and is discharged from the dust collector 100 (see the separation path X in FIG. 4).
　ここで、第２遠心分離部８０において、流出口８３ａに対する流入口８１の面積比率を大きくすると、第２遠心分離部８０による仕事率が増加するとともに、第２遠心分離部８０による騒音が低下する。流出口８３ａの面積をａとし、流入口８１の面積をｂとすると、流出口８３ａに対する流入口８１の面積比率ｂ／ａの好ましい範囲は、以下の通りである。 Here, in the second centrifuge 80, when the area ratio of the inlet 81 to the outlet 83a is increased, the work rate by the second centrifuge 80 increases and the noise by the second centrifuge 80 decreases. . The preferable range of the area ratio b / a of the inflow port 81 to the outflow port 83a is as follows, where a is the area of the outflow port 83a and b is the area of the inflow port 81.

　図７は、集塵装置１００における、第２遠心分離ユニット１２０と上部カバーユニット１３０との接続状態を示し、図７の（ａ）は斜視図であり、図７の（ｂ）は断面図である。図７の（ａ）及び（ｂ）に示されるように、第２遠心分離ユニット１２０の上蓋本体１２１及び上部カバーユニット１３０は、分離可能であり、後端部にて、互いに、ヒンジ１４０により接続されている。それゆえ、上部カバーユニット１３０は、ヒンジ１４０を軸として、第２遠心分離ユニット１２０に対して回転可能に設けられている。 1.075> b / a> 0.647
FIG. 7 shows a connection state of the second centrifugal separation unit 120 and the upper cover unit 130 in the dust collector 100, (a) of FIG. 7 is a perspective view, and (b) of FIG. 7 is a sectional view. is there. As shown in FIGS. 7A and 7B, the upper lid body 121 and the upper cover unit 130 of the second centrifuge unit 120 are separable and are connected to each other by a hinge 140 at the rear end. Has been. Therefore, the upper cover unit 130 is provided to be rotatable with respect to the second centrifuge unit 120 about the hinge 140 as an axis.
　また、上蓋本体１２１における、筒部１２１ａ及び閉塞部１２１ｂは、互いに、分離可能であり、ヒンジ１４０により接続されている。それゆえ、閉塞部１２１ｂは、ヒンジ１４０を軸として、筒部１２１ａに対して回転可能に設けられるとともに、筒部１２１ａから取り外すことができる。 Further, the cylinder part 121a and the closing part 121b in the upper lid main body 121 are separable from each other and are connected by a hinge 140. Therefore, the closing part 121b is provided so as to be rotatable with respect to the cylindrical part 121a around the hinge 140, and can be detached from the cylindrical part 121a.
　また、上蓋本体１２１及び上部カバーユニット１３０は、前端部にて、互いに、可動式クランプ１５０により着脱固定されている。 Also, the upper lid body 121 and the upper cover unit 130 are detachably fixed to each other by a movable clamp 150 at the front end.
　図７の（ａ）及び（ｂ）に示されるように、可動式クランプ１５０により、上蓋本体１２１及び上部カバーユニット１３０の固定が解除されると、閉塞部１２１ｂ及び上部カバーユニット１３０はそれぞれ、ヒンジ１４０を軸として、筒部１２１ａに対して回転可能になる。使用者は、閉塞部１２１ｂを筒部１２１ａに対して回転させ閉塞部１２１ｂを筒部１２１ａから取り外すことにより、第２遠心分離部８０それぞれの内部を水洗いすることができる。それゆえ、第２遠心分離部８０内部のメンテナンス性に優れた集塵装置１００を実現できる。 As shown in FIGS. 7A and 7B, when the upper lid main body 121 and the upper cover unit 130 are released by the movable clamp 150, the closing portion 121b and the upper cover unit 130 are hinged respectively. It becomes possible to rotate with respect to the cylinder part 121a about 140 as an axis. The user can wash the inside of each of the second centrifugal separators 80 by rotating the closing part 121b with respect to the cylindrical part 121a and removing the closing part 121b from the cylindrical part 121a. Therefore, the dust collector 100 excellent in maintainability inside the second centrifuge 80 can be realized.
　また、閉塞部１２１ｂは、シール性を有する部材により構成されており、筒部１２１ａとシール可能となっている。それゆえ、別途シール材や留め具を設けることなく、筒部１２１ａと閉塞部１２１ｂとの間のシール性が向上する。それゆえ、第２遠心分離部８０を構成する部材同士をシールするためにシール材や留め具を設ける必要がなく、部品点数を低減できる。 Further, the closing part 121b is made of a member having a sealing property and can be sealed with the cylindrical part 121a. Therefore, the sealing performance between the cylinder portion 121a and the closing portion 121b is improved without providing a separate sealing material or fastener. Therefore, it is not necessary to provide a sealing material or a fastener to seal the members constituting the second centrifugal separator 80, and the number of parts can be reduced.
　このように、第２遠心分離ユニット１２０の上蓋本体１２１は、旋回筒部８２が形成された旋回筒形成部分としての筒部１２１ａと、排気筒８３が設けられた排気筒形成部分としての閉塞部１２１ｂとが分離するように構成されている。そして、閉塞部１２１ｂは、軟質材により構成されている。それゆえ、第２遠心分離部８０内部のメンテナンス性に優れ、かつ、第２遠心分離部８０を構成する部品点数を低減できる集塵装置１００を実現できる。 As described above, the upper lid body 121 of the second centrifuge unit 120 includes the cylinder part 121a as the turning cylinder forming part in which the turning cylinder part 82 is formed, and the closing part as the exhaust cylinder forming part in which the exhaust cylinder 83 is provided. 121b is separated. And the obstruction | occlusion part 121b is comprised with the soft material. Therefore, it is possible to realize the dust collector 100 that is excellent in maintainability inside the second centrifugal separator 80 and that can reduce the number of parts constituting the second centrifugal separator 80.
　閉塞部１２１ｂを構成する部材は、筒部１２１ａとシール可能な材料であれば特に限定されないが、軟質材であることが好ましい。閉塞部１２１ｂを構成する軟質材としては、例えば、ゴム、ポリ塩化ビニル、エラストマー等の所謂軟質樹脂が挙げられ、成型容易性の観点から、エラストマーであることが好ましい。 Although the member which comprises the obstruction | occlusion part 121b will not be specifically limited if it is a material which can seal with the cylinder part 121a, It is preferable that it is a soft material. Examples of the soft material constituting the closing portion 121b include so-called soft resins such as rubber, polyvinyl chloride, and elastomer. From the viewpoint of ease of molding, an elastomer is preferable.
　また、第２遠心分離ユニット１２０は、第１遠心分離部７０の構成要素である内筒部１２３と第２遠心分離部８０との両方に連通する分岐空間部１２１ｅを有する。そして、閉塞部１２１ｂは、分岐空間部１２１ｅを塞ぐ天面蓋を構成する。 Further, the second centrifuge unit 120 has a branch space part 121e that communicates with both the inner cylinder part 123 and the second centrifuge part 80, which are components of the first centrifuge part 70. And the obstruction | occlusion part 121b comprises the top cover which plugs up the branch space part 121e.
　このため、第１遠心分離部７０の内筒部１２３から分岐空間部１２１ｅへ流入した空気は、天面蓋を構成する閉塞部１２１ｂに当り、側方へ向かい、流入口８１を介して第２遠心分離部８０へ流入する。そして、第２遠心分離部８０へ流入した空気は、天面蓋を構成する閉塞部１２１ｂに形成された流出口８３ａを介して外部へ排出される。 For this reason, the air that has flowed into the branch space portion 121e from the inner cylinder portion 123 of the first centrifugal separation portion 70 hits the closing portion 121b that constitutes the top cover, travels to the side, and passes through the inlet 81 to the second. It flows into the centrifuge 80. And the air which flowed into the 2nd centrifugation part 80 is discharged | emitted outside via the outflow port 83a formed in the obstruction | occlusion part 121b which comprises a top cover.
　また、天面蓋を構成する閉塞部１２１ｂは、筒部１２１ａと分離可能であり、ヒンジ１４０により接続されている。すなわち、閉塞部１２１ｂは、分岐空間部１２１ｅを開閉できるように構成されている。それゆえ、ユーザは、閉塞部１２１ｂを開放することにより、例えば第２遠心分離ユニット１２０内の分岐空間部１２１ｅを容易に清掃することが可能となる。したがって、清掃メンテナンス性が向上する。 Further, the closing part 121b constituting the top cover is separable from the cylindrical part 121a and is connected by a hinge 140. That is, the closing part 121b is configured to open and close the branch space part 121e. Therefore, the user can easily clean the branch space 121e in the second centrifuge unit 120, for example, by opening the closing part 121b. Therefore, cleaning maintenance performance is improved.
　〔実施形態２〕
　本発明の他の実施形態について、図８～図９に基づいて説明すれば、以下のとおりである。なお、説明の便宜上、前記実施形態にて説明した部材と同じ機能を有する部材については、同じ符号を付記し、その説明を省略する。 [Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.
　図８は、本実施形態に係る集塵装置１００Ａに備えられた第２遠心分離ユニット１２０Ａの構成を示す分解斜視図である。図９は、本実施形態に係る集塵装置１００Ａの構成を示す断面図である。 FIG. 8 is an exploded perspective view showing the configuration of the second centrifuge unit 120A provided in the dust collector 100A according to the present embodiment. FIG. 9 is a cross-sectional view showing a configuration of a dust collector 100A according to the present embodiment.
　図８及び図９に示されるように、本実施形態に係る集塵装置１００Ａは、第２遠心分離ユニット１２０Ａが防音材１２５及び防音カバー部材１２６を備えている点が前記実施形態１と異なる。第２遠心分離ユニット１２０Ａにおける、分岐空間部１２１ｅを塞ぐ閉塞部１２１ｆの下面の中央には、上方に窪んだ窪み部１２１ｇが設けられている。防音材１２５は、閉塞部１２１ｆの窪み部１２１ｇ内に充填されている。閉塞部１２１ｆは、軟質材により構成されている。閉塞部１２１ｆを構成する軟質材は、前記実施形態１における閉塞部１２１ｂと同様であるので、説明を省略する。防音材１２５を構成する材料は、例えば、発泡ゴム、ＰＰ発泡体、スポンジ、フェルト等が挙げられる。 8 and 9, the dust collector 100A according to the present embodiment is different from the first embodiment in that the second centrifugal separation unit 120A includes a soundproof material 125 and a soundproof cover member 126. In the second centrifuge unit 120A, a recess 121g that is recessed upward is provided at the center of the lower surface of the closing part 121f that closes the branch space part 121e. The soundproof material 125 is filled in the recess 121g of the closing part 121f. The closing part 121f is made of a soft material. Since the soft material which comprises the obstruction | occlusion part 121f is the same as that of the obstruction | occlusion part 121b in the said Embodiment 1, description is abbreviate | omitted. Examples of the material constituting the soundproofing material 125 include foam rubber, PP foam, sponge, felt, and the like.
　防音カバー部材１２６は、窪み部１２１ｇに充填された防音材１２５を被覆する部材であり、閉塞部１２１ｆの下面と面一になるように構成している。換言すると、第２遠心分離ユニット１２０Ａは、閉塞部１２１ｆの下面の中央に形成された窪み部１２１ｇと防音カバー部材１２６との間に空間が設けられており、この空間内に防音材１２５が充填された構成である。防音材１２５は、閉塞部１２１ｆ及び防音カバー部材１２６に接着されていない。 The soundproof cover member 126 is a member that covers the soundproof material 125 filled in the recess 121g, and is configured to be flush with the lower surface of the closing portion 121f. In other words, in the second centrifuge unit 120A, a space is provided between the recess 121g formed at the center of the lower surface of the closing part 121f and the soundproof cover member 126, and the soundproof material 125 is filled in this space. It is the structure which was made. The soundproof material 125 is not bonded to the closing portion 121f and the soundproof cover member 126.
　集塵装置１００Ａの第２遠心分離ユニット１２０Ａにおいて、分岐空間部１２１ｅは、第１遠心分離部７０の内筒ユニット１２２から流入する空気が複数の流入口８１を介して第２遠心分離部８０へ流出する箇所である。すなわち、分岐空間部１２１ｅは、第１遠心分離部７０から流入する空気が複数の第２遠心分離部８０へ分岐する分岐部として機能する。さらに、分岐空間部１２１ｅを閉塞する閉塞部１２１ｆには、第２遠心分離部８０の空気排出口である流出口８３ａが複数設けられている。このような構成を有する第２遠心分離ユニット１２０Ａでは、閉塞部１２１ｆが騒音の発生源となり得る。 In the second centrifugal separation unit 120A of the dust collector 100A, the branch space 121e is such that air flowing in from the inner cylinder unit 122 of the first centrifugal separation unit 70 is supplied to the second centrifugal separation unit 80 via the plurality of inlets 81. This is where it flows out. That is, the branch space part 121 e functions as a branch part where the air flowing in from the first centrifuge part 70 branches to the plurality of second centrifuge parts 80. Further, a plurality of outlets 83a that are air outlets of the second centrifugal separator 80 are provided in the closing part 121f that closes the branch space part 121e. In the second centrifuge unit 120A having such a configuration, the blocking portion 121f can be a noise generation source.
　本実施形態に係る集塵装置１００Ａの構成によれば、分岐空間部１２１ｅを構成する壁のうち、上部の壁は、閉塞部１２１ｆ及び防音カバー部材１２６により構成された２重壁構造となっている。さらに、閉塞部１２１ｆ及び防音カバー部材１２６の間に防音材１２５が充填されている。それゆえ、第２遠心分離ユニット１２０Ａの騒音発生源となり得る閉塞部１２１ｆに、防音材１２５及び前記２重壁構造といった防音構造を設けることによって、騒音を低減できる。また、防音材１２５は、露出せず、防音カバー部材１２６により被覆されている。それゆえ、防音材１２５に汚れが付着するのを防止できる。また、閉塞部１２１ｆを水洗いするに際し、防音材１２５に直接水が掛かることを防止できる。したがって、防音材１２５を備えた構成であっても、閉塞部１２１ｆを容易に水洗いすることができる。 According to the configuration of the dust collector 100A according to the present embodiment, the upper wall among the walls configuring the branch space 121e has a double wall structure configured by the closed portion 121f and the soundproof cover member 126. Yes. Furthermore, a soundproof material 125 is filled between the closing portion 121f and the soundproof cover member 126. Therefore, noise can be reduced by providing a soundproofing structure such as the soundproofing material 125 and the double wall structure in the closing part 121f that can be a noise generation source of the second centrifugal separation unit 120A. The soundproof material 125 is not exposed and is covered with a soundproof cover member 126. Therefore, it is possible to prevent dirt from adhering to the soundproof material 125. In addition, when the closed portion 121f is washed with water, it is possible to prevent the soundproof material 125 from being directly splashed with water. Therefore, even if it is the structure provided with the soundproof material 125, the obstruction | occlusion part 121f can be washed with water easily.
　なお、閉塞部１２１ｆは、前記２重壁構造を有していればよく、例えば、窪み部１２１ｇが下方に窪んだ構成であってもよい。この場合、窪み部１２１ｇは、閉塞部１２１ｆの上面の中央に設けられる。そして、防音材１２５は、閉塞部１２１ｆの窪み部１２１ｇ内に充填され、防音材１２５を被覆する防音カバー部材１２６は、閉塞部１２１ｆの上面と面一になるように構成している。 Note that the closing part 121f only needs to have the double wall structure, and for example, the recess 121g may be recessed downward. In this case, the recess 121g is provided at the center of the upper surface of the closing part 121f. The soundproofing material 125 is filled in the recess 121g of the closing part 121f, and the soundproofing cover member 126 that covers the soundproofing material 125 is configured to be flush with the upper surface of the closing part 121f.
　〔実施形態３〕
　本発明のさらに他の実施形態について、図１０～図１１に基づいて説明すれば、以下のとおりである。なお、説明の便宜上、前記実施形態にて説明した部材と同じ機能を有する部材については、同じ符号を付記し、その説明を省略する。 [Embodiment 3]
The following will describe still another embodiment of the present invention with reference to FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.
　図１０は、本実施形態に係る集塵装置１００Ｂの後方から見た分解斜視図である。図１１は、本発明形態に係る集塵装置１００Ｂの構成を示す断面図である。 FIG. 10 is an exploded perspective view seen from the rear of the dust collector 100B according to the present embodiment. FIG. 11 is a cross-sectional view illustrating a configuration of a dust collector 100B according to the present embodiment.
　図１０及び図１１に示されるように、本実施形態に係る集塵装置１００Ｂは、上蓋本体１２１及び上部カバーユニット１３０が、互いに、後端部にて引掛構造１４１により接続されている点が前記実施形態１と異なる。引掛構造１４１は、凸部１４２と、凹部１４３とから構成されている。凸部１４２は、上部カバーユニット１３０の下面の後端から下方に突出して設けられている。一方、凹部１４３は、凸部１４２と係合するように、第２遠心分離ユニット１２０の上蓋本体１２１の後端部に設けられている。凸部１４２には、後方に突出する係合爪部１４２ａが設けられている。また、凹部１４３には、係合爪部１４２ａと係合する係合穴部１４３ａが設けられている。上部カバーユニット１３０は、係合爪部１４２ａが係合穴部１４３ａに挿入され引掛かることにより、第２遠心分離ユニット１２０の上蓋本体１２１に開閉可能に接続している。 As shown in FIGS. 10 and 11, the dust collector 100 </ b> B according to the present embodiment is characterized in that the upper lid body 121 and the upper cover unit 130 are connected to each other by a hook structure 141 at the rear end. Different from the first embodiment. The hook structure 141 is composed of a convex portion 142 and a concave portion 143. The convex portion 142 is provided so as to protrude downward from the rear end of the lower surface of the upper cover unit 130. On the other hand, the concave portion 143 is provided at the rear end portion of the upper lid body 121 of the second centrifugal separation unit 120 so as to engage with the convex portion 142. The protrusion 142 is provided with an engaging claw 142a that protrudes rearward. Further, the recess 143 is provided with an engagement hole 143a that engages with the engagement claw 142a. The upper cover unit 130 is connected to the upper lid body 121 of the second centrifuge unit 120 so as to be openable and closable when the engaging claw 142a is inserted into the engaging hole 143a and hooked.
　本実施形態に係る集塵装置１００Ｂでは、可動式クランプ１５０により、上蓋本体１２１及び上部カバーユニット１３０の固定が解除されたとき、凹部１４３の係合穴部１４３ａから係合爪部１４２ａを離すことにより、容易に、第２遠心分離ユニット１２０の上蓋本体１２１から上部カバーユニット１３０を取り外すことができる。このように、集塵装置１００Ｂでは、上蓋本体１２１と上部カバーユニット１３０とを容易に取り外すことができるので、メンテナンス性が向上する。 In the dust collector 100B according to the present embodiment, when the upper lid body 121 and the upper cover unit 130 are released by the movable clamp 150, the engaging claw 142a is separated from the engaging hole 143a of the recess 143. Thus, the upper cover unit 130 can be easily detached from the upper lid body 121 of the second centrifuge unit 120. Thus, in the dust collector 100B, the upper lid main body 121 and the upper cover unit 130 can be easily removed, so that maintainability is improved.
　また、上蓋本体１２１と上部カバーユニット１３０との接続構造は、凸部１４２及び凹部１４３という２つの構成要素からなる。このように構成要素数が比較的小さいので、接続構造のサイズを小さくでき、集塵装置１００Ｂの小型化を図れる。 Further, the connection structure between the upper lid body 121 and the upper cover unit 130 is composed of two components, ie, a convex portion 142 and a concave portion 143. Thus, since the number of components is relatively small, the size of the connection structure can be reduced, and the dust collector 100B can be downsized.
