is possible to increase the dust suction amount when to expand the capacity of the dust storage chamber 16, unnecessarily increasing the size of the cleaner main body 7, and offend the requirements of size and weight. 【0028】上記課題を解決するために、吸気筒25と同心円上に外筒17が設けられ、その下端と一体に圧縮板18が配設されている。 [0028] In order to solve the above problems, the outer cylinder 17 is provided in the intake tube 25 concentric with the

この操作レバー28はスプリングバネ31によって上向きに付勢されているので、操作レバー28に押圧が加えられない状態においては外筒17及び圧縮板18は、図4に示す状態にあり、外筒17の開口部分はフィルタ2 This operation lever 28 is urged upward by the spring spring 31, the outer cylinder 17 and the compression plate 18 in a state where no pressing is applied to the operation lever 28 is in the state shown in FIG. 4, the outer tube 17 opening of the filter 2

2の空気と共に吸気流路26(図2参照)に流入させる吸気筒34と、この吸気筒34の同心円上に上下動自在に配設され、吸気筒34の下端側に設けられたフィルタ36に接するように下端周縁部に除塵体39が取り付けられた外筒38とを備えて構成されている。 An intake pipe 34 to flow into the intake passage 26 together with the second air (see FIG. 2), vertically movable disposed concentrically of the intake tube 34, the filter 36 provided at the lower side of the intake tube 34 Jochiritai 39 is configured to include an outer cylinder 38 which is attached to the lower peripheral edge in contact. 【0032】電動送風機61が駆動されると、前記吸込具3から吸入された塵埃を含む空気は塵埃分離室32内に流入する。 [0032] When the electric blower 61 is driven, air containing dust sucked from the suction unit 3 flows into the dust separation chamber 32. 図7は塵埃分離室32の水平方向断面を示すもので、流入した空気は略円筒形の塵埃分離室32の接線方向に導かれると共に、流路断面積が狭められることによって流速が増し、高速の旋回流となって塵埃分離室32の内周面に沿って下向き傾斜の流路を流れ、空気中の塵埃が遠心分離によって分離され、塵埃は一部の空気と共に流入口42から塵埃収容室33内に流入する。 Figure 7 shows a horizontal section of the dust separating chamber 32, with inlet air is directed in the tangential direction of the substantially cylindrical dust separating chamber 32, the flow rate is increased by the flow path cross-sectional area is narrowed, a high speed of a swirling flow flows the flow path of the downwardly inclined along the inner circumferential surface of the dust separating chamber 32, dust in the air is separated by centrifugation, dust dust storage chamber from the inlet port 42 with a portion of the air It flows into the 33.
旋回流の中心部分の空気は吸気筒34の下方側に設けられたフィルタ36で細かい塵埃が濾過されて吸気流路2 Air in the central portion of the swirling flow is fine dust filtered by the filter 36 provided on the lower side of the inlet pipe 34 and the intake passage 2
6を経て電動送風機61に吸引される。 It is sucked into the electric blower 61 via the 6. 【0033】塵埃分離室32から塵埃収容室33内に内周壁面に沿うように一部の空気と共に流入した塵埃は塵埃収容室33内に収容される。 The dust that has flowed together with a part of the air along the inner circumferential wall surface of the dust separating chamber 32 to the dust accommodating chamber 33 are accommodated in the dust accommodating chamber 33. 塵埃収容室33の略中央上方には吸気筒34に向かう吸引力が働いているので、 Since a substantially central upper portion of the dust accommodating chamber 33 is working suction force toward the inlet pipe 34,
塵埃収容室33内の空気は旋回流の速度が弱まる底部側から中央に引き寄せられて上昇し、吸気筒34への入口に設けられた第1フィルタ35を通って塵埃が濾過されて吸気筒34内に入り、塵埃分離室32の空気と共に第2フィルタ37を通って吸気流路26から電動送風機6 The air in the dust accommodating chamber 33 rises from the bottom side of the speed of the swirling flow is weakened is attracted to the center, the intake dust is filtered through the first filter 35 provided at the entrance to the inlet pipe 34 pipe 34 It enters the inside, the electric blower 6 from the intake passage 26 through the second filter 37 together with the air in the dust separating chamber 32
1に吸引される。 It is sucked into the 1. 【0034】吸気筒34はその側周面下端側にフィルタ36を設けた開口部から塵埃分離室32の空気を吸引するので、フィルタ36には微細な塵埃が付着するが、それを除去する作業がし難い位置にある。 [0034] Since the inlet pipe 34 for sucking air in the dust separating chamber 32 from the opening of the filter 36 provided in the side peripheral surface lower end, but the filter 36 adheres fine dust to remove it work in the difficult position. また、塵埃収容室33に堆積する塵埃のなかで繊維質のものは、ふんわりとして嵩高い状態で堆積し、塵埃収容室33の塵埃収容容積を占拠するので吸塵量を低下させることになる。 Further, those of fibrous among dust deposited dust accommodating chamber 33 is formed by depositing a bulky state as soft, will reduce the dust suction amount so occupying the dust storage volume of the dust accommodating chamber 33.
塵埃収容室33の容積を拡大させると吸塵量を増加させることができるが、徒に掃除機本体7を大型化させ、小型軽量化の要求にそぐわないものとなる。 Although it is possible to increase the dust suction amount when to expand the capacity of the dust storage chamber 33, unnecessarily increasing the size of the cleaner main body 7, and offend the requirements of size and weight. 【0035】上記課題を解決するために、吸気筒34と同心円上の上方に外筒38が上下移動可能に配設されている。 [0035] In order to solve the above problems, the outer cylinder 38 is disposed vertically movably above the inlet pipe 34 and concentrically. 外筒38には、その下端に先端部が前記フィルタ36に接する除塵体39が設けられ、一側周面には直径方向に外方に延出させた操作レバー40が形成されている。 The outer cylinder 38 has its lower end dust removal body 39 tip is in contact with the filter 36 is provided in, on one side peripheral surface is formed with the operating lever 40 which is extended outward in the diameter direction. この操作レバー40はスプリングバネ41によって上向きに付勢されているので、操作レバー40に押圧が加えられない状態においては外筒38は図6に示す状態にある。 This operation lever 40 is urged upward by the spring spring 41, in a state where no pressing is applied to the operation lever 40 the outer cylinder 38 is in a state shown in FIG. 【0036】図8は、前記操作レバー40を押圧操作した状態を示すもので、操作レバー40の押圧操作により外筒38が下降すると、下降動作によって前記除塵体3 [0036] Figure 8, the operation lever 40 indicates a pressed state, the outer cylinder 38 is lowered by the pressing operation of the operating lever 40, the dust removal body by lowering operation 3
9がフィルタ36の表面に付着した塵埃を除塵体39が掻き落としてフィルタ36を清掃する。 9 to clean the filter 36 scrapes off Jochiritai 39 dust adhering to the surface of the filter 36 is. 外筒38が吸気筒34の下端まで下降すると、吸気筒34のフィルタ3 When outer cylinder 38 is moved down to the lower end of the inlet pipe 34, filter 3 of the inlet pipe 34
6面は閉じられるので、塵埃分離室32内から吸気筒3 Since six sides is closed, the intake tube 3 from the dust separating chamber 32
4への吸気は停止される。 Intake to 4 is stopped. 従って、吸気筒34の吸気は塵埃収容室33に集中し、塵埃分離室32内の空気も全て塵埃収容室33に流れるので、塵埃収容室33から吸気筒34への吸引力が急増する。 Therefore, the intake of the inlet pipe 34 to concentrate on the dust accommodating chamber 33, so also all air dust separation chamber 32 flows into the dust accommodating chamber 33, the suction force from the dust accommodating chamber 33 to the intake pipe 34 is rapidly increased. 塵埃収容室33内に集塵された塵埃のうち、繊維質の塵埃は軽量でふんわりしているため吸気筒34への吸引力が急増すると、図示するように第1フィルタ35の下に吸引され、繊維質の塵埃が集まって圧縮される。 Of the dust collection is dust in the dust storage chamber 33, dust fibrous when the suction force of the suction tube 34 because of the soft lightweight increases rapidly, is sucked under the first filter 35 as shown , it is compressed gathered dust of fiber. 【0037】操作レバー40に対する押圧を解除すると、操作レバー40はスプリングバネ41の付勢により押し上げられて外筒38が上昇するので、吸気筒34のフィルタ36の面は開放され、図6に示す状態に復帰する。 [0037] Upon releasing the pressure on the operation lever 40, the operating lever 40 because the outer cylinder 38 is pushed up by the urging of the spring the spring 41 is increased, the surface of the filter 36 of the inlet pipe 34 is opened, shown in Figure 6 to return to the state. この状態では塵埃分離室32から吸気筒34への吸気が発生するので、塵埃収容室33から吸気筒34への吸気量は減少し、第1フィルタ35の下に圧縮された塵埃を吸着していた吸引力は下がるので、圧縮された塵埃は落下して塵埃収容室33の底面上にある他の塵埃と一緒になり、圧縮されたことにより全体の塵埃体積が減少する。 Since in this state the intake from the dust separating chamber 32 to the intake pipe 34 occurs, the intake air amount from the dust accommodating chamber 33 to the intake pipe 34 decreases, adsorbed dust compressed under the first filter 35 since the suction force decreases, compressed dust to fall to be with other dust present on the bottom surface of the dust storage chamber 33, the total dust volume by compressed is reduced. 【0038】この操作レバー40の押圧操作は、電動送風機61を駆動させた任意のタイミングで行なうことができるが、電気掃除機1で掃除を開始する前に操作すると、フィルタ36が清掃され、堆積した塵埃を圧縮して塵埃収容室33の余剰容積が拡大するので、集塵能力が低下しない状態で電気掃除機1を使用することができる。 The pressing operation of the operating lever 40 can be carried out at any timing of driving the electric blower 61, is operated before starting the cleaning in the electric vacuum cleaner 1, the filter 36 is cleaned, the deposition since excess volume of the dust accommodating chamber 33 by the the dust compression is enlarged, it is possible to dust collecting ability to use the electric vacuum cleaner 1 in a state that does not decrease. 【0039】上記のように塵埃分離室32の空気を吸気筒34から吸気する状態を開閉操作して、塵埃収容室3 [0039] In a state of intake air in the dust separating chamber 32 from the intake pipe 34 as described above is opened and closed, the dust storage chamber 3
3内の塵埃を圧縮する構成は、図9に示すような構造を適用することもできる。 Configured to compress the dust in 3 it can also be applied a structure as shown in FIG. 【0040】図9において、円筒形の吸気筒44はその側周面に軸心方向にフィルタ(図示省略)を配した複数の通気口44aが円周方向に列設形成されており、この吸気筒44の外周面上を回動できるように外筒45が配設されている。 [0040] In FIG. 9, a plurality of vent holes 44a intake tube 44 of the cylindrical decor filter (not shown) in the axial direction on the side peripheral surface is arrayed formed in the circumferential direction, the intake the outer cylinder 45 is disposed so that it can rotate on the outer peripheral surface of the cylinder 44. 外筒45には前記通気口44aに対応させて複数の開口部45aが形成され、一側周面には直径方向に延出させて操作レバー46が形成され、操作レバー46はスプリングバネ47によって円周方向に付勢されている。 The outer cylinder 45 is formed with a plurality of openings 45a in correspondence with the vent 44a, the one side periphery are formed operating lever 46 is extended in the radial direction, the operating lever 46 by the spring spring 47 and it is biased in the circumferential direction. 【0041】前記操作レバー46を操作しない状態においては、図9(a)に示すように、吸気筒44の通気口44aと外筒45の開口部45aとは、それぞれの位置が一致して塵埃分離室32内の空気は開口部45a及び通気口44aを通って吸気筒44内に吸気される。 [0041] In a state where no operating the operating lever 46, as shown in FIG. 9 (a), and the opening 45a of the vents 44a and the outer cylinder 45 of the intake tube 44, each position is coincident dust air separation chamber 32 is sucked into the inlet pipe 44 through the openings 45a and vent 44a. 図9 Figure 9
(b)に示すように、操作レバー46を押圧すると、外筒45は回動して開口部45aが形成されていない部位で吸気筒44の通気口44aを閉じる状態になる。 As (b), when pressing the operating lever 46, the outer cylinder 45 is in a state of closing the vent opening 44a of the inlet pipe 44 at a site that is not rotated and the opening 45a and is formed. この状態では塵埃分離室32内の空気は吸気筒44には吸気されず、吸気筒44に吸気されるのは塵埃収容室33だけとなり、先に図8に示したように、繊維質のような軽く嵩高い塵埃は第1フィルタ35の下面に吸引されて圧縮される。 Not the intake air in the intake pipe 44 is an air dust separation chamber 32 in this state, being sucked into the inlet pipe 44 is only the dust accommodating chamber 33, as shown in FIG. 8 above, as a fibrous Do lightly bulky dust is compressed is sucked to the lower surface of the first filter 35. 従って、電気掃除機1を運転した状態で操作レバー46を押圧操作すると、塵埃収容室33内の嵩高い塵埃は圧縮され、塵埃収容室33の余剰容積が拡大するので、集塵能力が低下しない状態で電気掃除機1を使用することができる。 Therefore, when pushing the operation lever 46 in a state of operating the electric vacuum cleaner 1, bulky dust in the dust accommodating chamber 33 is compressed, since the enlarged surplus capacity of the dust storage chamber 33, the dust collection capacity is not reduced it is possible to use a vacuum cleaner 1 in the state. 【0042】(第3の実施形態)図10は、第3の実施形態に係る集塵ケース13とその周辺部の構成を示すもので、本体ケース60の前方側に着脱可能に装着されている。 [0042] FIG. 10 (Third Embodiment) in which the dust collecting case 13 according to the third embodiment showing the construction of the peripheral portion, and is detachably mounted on the front side of the main body case 60 . 尚、第1及び第2の各実施形態の構成と共通する構成要素には同一の符号を付して、その説明は簡略にする。 Incidentally, the constituent elements common to the configuration of the first and second embodiments are denoted by the same reference numerals, and description thereof will be simplified. 【0043】集塵ケース13は、吸気された塵埃を含む空気を旋回流に形成して空気中から塵埃を遠心分離する塵埃分離室50と、この塵埃分離室50からの旋回流が流入して遠心分離された塵埃を収容する塵埃収容室51 The dust-collection case 13, a dust separation chamber 50 for centrifuging dust from forming air swirling flow air containing air is dust, swirling flow from the dust separation chamber 50 flows into dust accommodating chamber 51 for accommodating the centrifuged dust

2とを備えて構成されている。 It is constituted by a 2. 【0044】電動送風機61が駆動されると、前記吸込具3から吸入された塵埃を含む空気は吸気口20から塵埃分離室50内に流入する。 [0044] When the electric blower 61 is driven, air containing dust sucked from the suction unit 3 flows from the intake port 20 into the dust separation chamber 50. 流入した空気は誘導流路1 Inlet air induction passage 1
4により略円筒形の塵埃分離室50の接線方向に導かれると共に、流路断面積が狭められることによって流速が増し、高速の旋回流となって塵埃分離室50の内周面に沿って下向き傾斜の流路を流れ、空気中の塵埃が遠心分離され、分離された塵埃は一部の空気と共に塵埃収容室51内に流入する。 With guided in the tangential direction of the dust separating chamber 50 of generally cylindrical form by 4, the flow rate is increased by the flow path cross-sectional area is narrowed, along the inner circumferential surface of the dust separating chamber 50 becomes high-speed swirling flow downward flow the flow path slope, dust in the air is centrifuged, separated dust flows into the dust accommodating chamber 51 with a portion of the air. 【0045】略円筒形に形成された塵埃収容室51内に内周壁面に沿うように流入した塵埃は塵埃収容室51の底面周囲から堆積していき、空気は旋回流が弱まる底部側から塵埃収容室51の略中央上方に働く吸気によって上昇し、第1フィルタ53で細かい塵埃が濾過され、塵埃分離室50内の空気と共に第2フィルタ55を通って吸気流路26から電動送風機61に吸引される。 [0045] The inflow dust along the inner peripheral wall surface in a substantially cylindrical dust receiving chamber 51 formed gradually deposited from the bottom periphery of the dust accommodating chamber 51, dust from the bottom side air swirling flow is weakened acting substantially in the center above the accommodating chamber 51 rises due to the intake, fine dust in the first filter 53 is filtered, sucked into the electric blower 61 from the intake passage 26 through the second filter 55 together with the air in the dust separation chamber 50 It is. 【0046】塵埃収容室51内に堆積する塵埃のなかで繊維質のものは、ふんわりとして嵩高い状態で堆積し、 [0046] those of fibrous among dust deposited dust accommodating chamber 51 is formed by depositing a bulky state as fluffy,
塵埃収容室51の塵埃収容容積を占拠するので吸塵量を低下させることになる。 Since it occupies dust storage volume of the dust accommodating chamber 51 will reduce the dust suction amount. 塵埃収容室51の容積を拡大させると吸塵量を増加させることができるが、徒に掃除機本体7を大型化させ、小型軽量化の要求にそぐわないものとなる。 Although it is possible to increase the dust suction amount when to expand the volume of the dust accommodating chamber 51, unnecessarily increasing the size of the cleaner main body 7, and offend the requirements of size and weight. 【0047】この課題を解決するために、塵埃収容室5 [0047] In order to solve this problem, the dust receiving chamber 5
1の底面側と塵埃分離室50の入口との間の空気流路を形成する循環流路52が設けられている。 Circulation passage 52 forming an air flow path between the inlet of one of the bottom side and the dust separation chamber 50 is provided. 塵埃収容室5 Dust receiving chamber 5
1の底面側にはフィルタ(図示省略)を設けた循環空気穴54が形成されており、塵埃収容室51内の一部の空気は循環空気穴54から循環流路52に流れる。 The first bottom surface is formed circulating air hole 54 provided with a filter (not shown), a part of the air in the dust accommodating chamber 51 flows from the circulating air holes 54 in the circulation passage 52. 塵埃分離室50の入口は誘導流路14により前述したように高速の旋回流が形成されているので、その負圧により入口に開口する循環流路52内の空気は塵埃分離室50内に引き込まれ、空気の一部が循環することになる。 Since the inlet of the dust separating chamber 50 faster swirling flow as described above by the induction passage 14 is formed, air in the circulation flow path 52 which opens to the inlet by its negative pressure drawn into the dust separation chamber 50 is, a part of the air is circulated. 【0048】塵埃収容室51の底面側から空気の一部が流出することにより、底面上に堆積する塵埃は流出する空気の流れにのり、圧縮された状態に堆積し、圧縮されたことにより全体の塵埃堆積量が減少する。 The whole by part of the air from the bottom side of the dust storage chamber 51 flows out, dust deposited on the bottom glue to a flow of air flowing out by depositing the compressed state, the compressed the amount is reduced dust deposition. 【0049】図11に示す構成は、循環流路56を集塵ケース13aの把手9内に形成したものである。 The configuration shown in FIG. 11 is obtained by forming the circulation flow path 56 within the handle 9 of the dust-collecting case 13a. 把手9 Handle 9
