Description

本発明は、吸気を旋回流にすることにより遠心分離により塵埃を含む空気中から塵埃を分離するサイクロン方式の集塵部を備えた電気掃除機に関する。   The present invention relates to a vacuum cleaner provided with a cyclone type dust collecting unit that separates dust from air containing dust by centrifugal separation by turning swirling air.

サイクロン方式の集塵部を備えた電気掃除機は、塵埃の集塵量の増加に伴う吸気能力の低下が少ないことや、紙パックのような集塵のための消耗品が不要であることなどの特徴を有している。   Vacuum cleaners equipped with a cyclone type dust collector have little reduction in air intake capacity due to an increase in the amount of dust collected, and do not require consumables for dust collection such as paper packs. It has the characteristics.

上記サイクロン方式の集塵部を備えた電気掃除機の従来技術としては、例えば、特許文献1や特許文献2に開示されたものが知られており、吸気された塵埃を含む空気を旋回流に形成することによって遠心分離により空気中から塵埃を分離し、分離された塵埃を集塵部の下部に堆積させるように構成されている。   As a prior art of the vacuum cleaner provided with the said cyclone type dust collecting part, what was disclosed by patent document 1 and patent document 2, for example is known, and the air containing the inhaled dust is made into a swirl flow. By forming, dust is separated from the air by centrifugal separation, and the separated dust is deposited at the lower part of the dust collecting portion.

図12は、従来技術に係るサイクロン方式電気掃除機の掃除機本体の構成を示すものである。掃除機本体100に内蔵された電動送風機101を回転させることにより、先端に吸込具が連結された吸気ホース(図示省略)が接続される吸気口102から吸引された塵埃を含む空気は、吸気を旋回流に形成する誘導流路103から塵埃分離室104内に流入する。塵埃分離室104は、図13に示すように略円筒形に形成され、前記誘導流路103により吸気された空気の流れ方向が円筒の接線方向になり、流路断面積が狭められることにより、塵埃分離室104内に流入した空気は高速の旋回流となり、旋回流による遠心分離により空気中から塵埃が分離され、分離された塵埃は流入口105から一部の空気と共に塵埃収容室106に流入し、塵埃収容室106の底に堆積する。塵埃収容室106の空気は略中央部から第1フィルタ107を通り、塵埃分離室104の空気と共に第2フィルタ108を通って電動送風機101に吸引される。

FIG. 12 shows a configuration of a vacuum cleaner body of a cyclone type electric vacuum cleaner according to the prior art. By rotating the electric blower 101 built in the vacuum cleaner main body 100, the air containing dust sucked from the intake port 102 to which the suction hose (not shown) having a suction tool connected to the tip is connected, It flows into the dust separation chamber 104 from the guide channel 103 formed in the swirl flow. The dust separation chamber 104 is formed in a substantially cylindrical shape as shown in FIG. 13, and the flow direction of the air sucked in by the guide flow path 103 becomes the tangential direction of the cylinder, and the cross-sectional area of the flow path is narrowed. The air flowing into the dust separation chamber 104 becomes a high-speed swirling flow, and the dust is separated from the air by centrifugal separation by the swirling flow, and the separated dust flows into the dust containing chamber 106 together with a part of the air from the inlet 105. And deposits on the bottom of the dust chamber 106. The air in the dust storage chamber 106 passes through the first filter 107 from substantially the center, and is sucked into the electric blower 101 through the second filter 108 together with the air in the dust separation chamber 104.
JP 2000-342492 A Japanese Patent Laid-Open No. 9-253011

従来のサイクロン方式の電気掃除機にあっては、上記のように塵埃収容室106内に単純に堆積させるだけでるため、塵埃が繊維質のものが多い場合に集塵した質量の割には嵩張った状態になる。従って、集塵ケースの容積に比して集塵量が少なくなり、大型の集塵ケースを搭載することになり、電気掃除機の小型軽量化の流れに逆行することになる。   The conventional cyclone type vacuum cleaner simply deposits in the dust storage chamber 106 as described above, so that it is bulky for the mass collected when the dust is mostly fibrous. It becomes a stretched state. Therefore, the amount of dust collection is smaller than the volume of the dust collection case, and a large dust collection case is mounted, which goes against the trend of reducing the size and weight of the vacuum cleaner.

本発明が目的とするところは、サイクロン方式の特徴を生かしつつ塵埃の圧縮機能を設けて集塵容量の増大化を図った電気掃除機を提供することにある。   An object of the present invention is to provide an electric vacuum cleaner in which a dust compression function is provided and a dust collection capacity is increased while taking advantage of the characteristics of the cyclone system.

上記目的を達成するための本願発明は、電動送風機によって発生させた吸引風により吸込具から吸引した塵埃を含む空気を集塵ケースに導き、遠心分離により空気中から塵埃を分離して集塵する電気掃除機において、前記集塵ケースは、吸引風を旋回流にして空気中の塵埃を遠心分離する塵埃分離室と、分離された塵埃を堆積させる塵埃収容室とを備え、この塵埃収容室の略中央部から前記塵埃分離室の中央部を通って前記電動送風機につながる空気流路を形成すると共に、前記塵埃収容室の底部側から塵埃分離室より上流側の吸気流路につながる循環流路が形成されてなることを特徴とするもので、循環流路により塵埃収容室の下方側から塵埃分離室の上流側に空気の流れが形成されるので、塵埃収容室内の塵埃は循環流路への流れによって圧縮され、塵埃収容室の容積を拡大させることなく塵埃収容量を増加させることができる。 In order to achieve the above object, the present invention is directed to collecting air collected by sucking air from a suction tool into a dust collecting case by suction air generated by an electric blower and separating the dust from the air by centrifugation. In the vacuum cleaner, the dust collection case includes a dust separation chamber for centrifugally separating the dust in the air using a swirl flow and a dust storage chamber for depositing the separated dust. A circulation flow path that forms an air flow path that leads from the substantially central portion through the central portion of the dust separation chamber to the electric blower and that connects from the bottom side of the dust storage chamber to the intake flow passage upstream of the dust separation chamber. Since the air flow is formed from the lower side of the dust chamber to the upstream side of the dust separation chamber by the circulation channel, the dust in the dust chamber is transferred to the circulation channel. By the flow of It is compressed, thereby increasing the dust storage amount without increasing the volume of the dust storage chamber.

上記構成において、集塵ケースを略円筒状に形成し、塵埃収容室の底面側に循環流路への出口を形成することにより、塵埃収容室内の周面に沿う旋回流の一部は下降して底面側に形成された循環経路に流れるので、塵埃は底面側に引かれて塵埃の堆積と共に圧縮が進行する。   In the above configuration, the dust collection case is formed in a substantially cylindrical shape, and an outlet to the circulation channel is formed on the bottom surface side of the dust chamber, so that a part of the swirl flow along the peripheral surface of the dust chamber falls. Thus, the dust flows to the circulation path formed on the bottom surface side, so that the dust is attracted to the bottom surface side and the compression proceeds with the accumulation of the dust.

上記循環流路は、集塵ケースに形成された把手の内部空間として形成することができ、集塵ケースはそれに溜まった塵埃を捨て、清掃するために把手を持って掃除機本体から取り出せるように構成されるが、その把手の中に空間を形成して空間を循環流路とすると、集塵ケースを大型化させることなく循環流路を形成することができる。   The circulation channel can be formed as an internal space of a handle formed in the dust collection case, and the dust collection case can be removed from the main body of the vacuum cleaner by holding the handle for discarding the dust and cleaning it. However, if a space is formed in the handle and the space is used as a circulation channel, the circulation channel can be formed without increasing the size of the dust collecting case.

以上説明した通り本願発明によれば、塵埃収容室の底面側から空気の一部を吸気する循環流路を形成して、循環流路への空気の流れにより塵埃を圧縮することができるので、塵埃収容室の塵埃収容量を増加させることができる。 As described above , according to the present invention, it is possible to form a circulation passage that sucks a part of air from the bottom surface side of the dust storage chamber, and to compress dust by the flow of air to the circulation passage. The amount of dust contained in the dust chamber can be increased.

以下、添付図面を参照して本発明に関する参考例及び本発明の実施形態について説明し、本発明の理解に供する。尚、以下に示す実施形態は本発明を具体化した一例であって、本発明の技術的範囲を限定するものではない。   Hereinafter, reference examples and embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.

第1の参考例)
図2は、本発明に関する第1の参考例に係る集塵ケース11及びそ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。集塵ケース11は、吸気された塵埃を含む空気を誘導流路14に通して形成した旋回流による遠心力によって空気中から塵埃を分離する塵埃分離室15と、この塵埃分離室15から流入した塵埃を収容する塵埃収容室16と、この塵埃収容室16の空気を略中央部上方から吸気して前記塵埃分離室15の空気と共に吸気流路26に流入させる吸気筒25と、この吸気筒25の同心円上を軸心方向に移動可能に配設され、吸気筒25の側周面の軸方向に形成された開口部に設けられたフィルタ21に接するように内周面にブラシ毛(除塵体)22が取り付けられた外筒17と、この外筒17の下端と一体に形成されて塵埃分離室15と塵埃収容室16との間を区画して外筒17の軸心方向への移動により塵埃収容室16内に進退移動する圧縮板18とを備えて構成されている。
( First reference example)
FIG. 2 shows a dust collection case 11 and its configuration according to a first reference example relating to the present invention, which is detachably attached to the front side of the main body case 60. The dust collection case 11 flows from the dust separation chamber 15 and the dust separation chamber 15 that separates the dust from the air by centrifugal force generated by the swirling flow formed by passing the air containing the sucked dust through the guide passage 14. A dust storage chamber 16 that stores dust, an intake cylinder 25 that sucks the air in the dust storage chamber 16 from substantially above the center and flows into the intake passage 26 together with the air of the dust separation chamber 15, and the intake cylinder 25 The brush bristles (dust removers) are arranged on the inner peripheral surface so as to be in contact with the filter 21 provided in the opening formed in the axial direction of the side peripheral surface of the intake cylinder 25. ) 22 is attached to the outer cylinder 17, and the lower end of the outer cylinder 17 is integrally formed to partition the dust separation chamber 15 and the dust storage chamber 16 and move the outer cylinder 17 in the axial direction. A compression plate that moves forward and backward in the dust chamber 16 It is constituted by a 8.

本体ケース60に形成された吸気口20には前記ホース継ぎ手5が連結され、本体ケース60内に配設された電動送風機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前記吸気口20から塵埃分離室15内に流入する。図3は塵埃分離室15の水平方向断面を示すもので、誘導流路14によって流入した空気は略円筒形の塵埃分離室15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15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、一部の空気と共に流入口27から塵埃収容室16内に流入する。塵埃分離室15内の旋回流の中心部分の空気は塵埃がほとんど無い状態になっているが、第2フィルタ24を通って細かい塵埃が濾過され、吸気流路26から電動送風機61に吸引される。   The hose joint 5 is connected to the intake port 20 formed in the main body case 60, and when the electric blower 61 disposed in the main body case 60 is driven, the air containing dust sucked from the suction tool 3. Flows into the dust separation chamber 15 from the intake port 20. FIG. 3 shows a horizontal section of the dust separation chamber 15, and the air flowing in by the guide channel 14 is guided in the tangential direction of the substantially cylindrical dust separation chamber 15 and the channel cross-sectional area is narrowed. The flow velocity increases, and a high-speed swirling flow flows along the downwardly inclined flow path along the inner peripheral surface of the dust separation chamber 15. The dust in the air is separated by centrifugal separation, and from the inlet 27 together with some air. It flows into the dust chamber 16. The air in the central portion of the swirling flow in the dust separation chamber 15 is almost free of dust, but fine dust is filtered through the second filter 24 and sucked into the electric blower 61 from the intake passage 26. .

略円筒形に形成された塵埃収容室16内に内周壁面に沿うように流入した塵埃のうち、質量の大きい砂ゴミ等の塵埃は塵埃収容室16の底面周囲に集まり、質量の小さい綿ゴミ等の塵埃は旋回する空気の流れと共に旋回し、電気掃除機1の運転が停止されたときに塵埃収容室16の底に堆積する。塵埃収容室16の略中央上方には吸気筒25に向かう吸引力が働いているので、塵埃収容室16内の空気は旋回する流れが弱まった底部側から中央に引き寄せられて上昇し、吸気筒25の底面に設けられた第1フィルタ19で微細な塵埃が濾過され、塵埃分離室15内からフィルタ21を通って吸気筒25内に入った空気と共に吸気筒25内から第2フィルタ24を通って吸気流路26から電動送風機61に吸引される。   Of the dust that has flowed into the dust storage chamber 16 formed in a substantially cylindrical shape along the inner peripheral wall surface, dust such as sand dust having a large mass gathers around the bottom surface of the dust storage chamber 16 and cotton dust having a small mass. The dust such as dust swirls with the swirling air flow and accumulates on the bottom of the dust storage chamber 16 when the operation of the electric vacuum cleaner 1 is stopped. Since a suction force toward the intake cylinder 25 is acting substantially above the center of the dust storage chamber 16, the air in the dust storage chamber 16 is attracted to the center from the bottom side where the swirling flow is weakened and rises. Fine dust is filtered by the first filter 19 provided on the bottom surface of the air 25, and the air that has entered the intake cylinder 25 through the filter 21 from the dust separation chamber 15 passes through the second filter 24 from the intake cylinder 25. Then, the air is sucked into the electric blower 61 from the intake passage 26.

前記吸気筒25は、図3及び図4に示すように、側周面に円筒形の軸心方向にフィルタ21を設けた複数の開口部が形成されている。吸気筒25はフィルタ21を設けた開口部から塵埃分離室15の空気を吸引するので、遠心分離されなかった微細な塵埃がフィルタ21に付着するが、それを除去する作業がし難い位置にある。また、塵埃収容室16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16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。塵埃収容室16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。   As shown in FIGS. 3 and 4, the intake cylinder 25 has a plurality of openings provided with filters 21 in the axial direction of the cylindrical shape on the side peripheral surface. Since the suction cylinder 25 sucks the air in the dust separation chamber 15 from the opening provided with the filter 21, fine dust that has not been centrifuged adheres to the filter 21, but is in a position where it is difficult to remove it. . Further, among the dust accumulated in the dust chamber 16, the fibrous material accumulates in a soft and bulky state, and occupies the dust volume of the dust chamber 16, thereby reducing the amount of dust absorbed. If the volume of the dust storage chamber 16 is increased, the amount of dust absorption can be increased. However, the vacuum cleaner body 7 is increased in size, which does not meet the demand for reduction in size and weight.

そして、第1の参考例では、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。外筒17は、塵埃分離室15から吸気筒25内への通気を阻害しないように複数の開口部17aが形成され、下端に圧縮板18を一体に形成すると共に、把手28が設けられている。図4は集塵ケース11を図2に示した状態と異なる断面で示すもので、外筒17の一側周面には図3に示すように直径方向に外方に延出させた操作レバー28が形成されている。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21に対向する位置に形成されている。 In the first reference example, the outer cylinder 17 is provided concentrically with the intake cylinder 25, and the compression plate 18 is disposed integrally with the lower end thereof. The outer cylinder 17 is formed with a plurality of openings 17a so as not to impede ventilation from the dust separation chamber 15 into the intake cylinder 25, and a compression plate 18 is integrally formed at the lower end, and a handle 28 is provided. . FIG. 4 shows the dust collecting case 11 in a cross section different from the state shown in FIG. 2, and an operating lever extended outward in the diameter direction as shown in FIG. 28 is formed. Since the operation lever 28 is biased upward by the spring spring 31, the outer cylinder 17 and the compression plate 18 are in the state shown in FIG. 4 when the operation lever 28 is not pressed. Is formed at a position facing the filter 21.

図5は、前記操作レバー28を押圧操作した状態を示すもので、操作レバー28の押圧操作により外筒17が下降すると、外筒17の上方内周面にフィルタ21に対向するように設けられたブラシ毛22は外筒17の下降に従ってフィルタ21の表面を擦って付着した塵埃を掻き落とす。更に、外筒17の下端に一体化された圧縮板18は外筒17の下降に従って塵埃収容室16内に堆積した塵埃を圧縮する。この操作レバー28の押圧操作は、電動送風機61が停止している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21が清掃され、堆積した塵埃、特に嵩高い繊維質の塵埃を圧縮して塵埃収容室16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。   FIG. 5 shows a state in which the operation lever 28 is pressed. When the outer cylinder 17 is lowered by the pressing operation of the operation lever 28, the operation lever 28 is provided on the upper inner peripheral surface of the outer cylinder 17 so as to face the filter 21. The brush bristles 22 scrape off adhering dust by rubbing the surface of the filter 21 as the outer cylinder 17 descends. Further, the compression plate 18 integrated with the lower end of the outer cylinder 17 compresses the dust accumulated in the dust storage chamber 16 as the outer cylinder 17 descends. The pressing operation of the operation lever 28 can be performed at any timing when the electric blower 61 is stopped. However, if the operation is performed before the electric vacuum cleaner 1 starts cleaning, the filter 21 is cleaned and accumulated dust. In particular, the bulky fibrous dust is compressed and the excess volume of the dust storage chamber 16 is expanded, so that the vacuum cleaner 1 can be used without reducing the dust collection capability.

(第参考例
図6及び図7は、第参考例に係る集塵ケース12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。尚、第1の参考例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。
( Second reference example )
FIGS. 6 and 7 show the configuration of the dust collection case 12 according to the second reference example , which is detachably attached to the front side of the main body case 60. In addition, the same code | symbol is attached | subjected to the component which is common in the structure of a 1st reference example, and the description is simplified.

集塵ケース12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32と、この塵埃分離室32で遠心分離された塵埃を収容する塵埃収容室33と、この塵埃収容室33内の空気を略中央上方から吸気して前記塵埃分離室32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。   The dust collecting case 12 forms a swirling flow of air containing the sucked dust, and separates dust from the air. The dust collecting chamber 12 holds dust that has been centrifuged in the dust separating chamber 32. A chamber 33, an intake cylinder 34 for sucking air in the dust storage chamber 33 from substantially above the center and flowing into the intake passage 26 (see FIG. 2) together with the air in the dust separation chamber 32, and the intake cylinder 34 The outer cylinder 38 is arranged on a concentric circle so as to be movable up and down and has a dust removing body 39 attached to the peripheral edge of the lower end so as to contact a filter 36 provided on the lower end side of the intake cylinder 34.

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。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。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26を経て電動送風機61に吸引される。   When the electric blower 61 is driven, the air containing the dust sucked from the suction tool 3 flows into the dust separation chamber 32. FIG. 7 shows a horizontal cross section of the dust separation chamber 32. Inflowed air is guided in the tangential direction of the substantially cylindrical dust separation chamber 32, and the flow velocity is increased by narrowing the cross-sectional area of the flow path. , And flows in a downwardly inclined channel along the inner peripheral surface of the dust separation chamber 32, dust in the air is separated by centrifugation, and the dust is collected from the inlet 42 together with a part of the air from the inlet 42. 33 flows into. The air in the central portion of the swirling flow is filtered by a filter 36 provided on the lower side of the intake cylinder 34 and is sucked into the electric blower 61 through the intake passage 26.

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。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、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61に吸引される。   Dust that flows in along with the inner peripheral wall surface from the dust separation chamber 32 into the dust storage chamber 33 together with a part of the air is stored in the dust storage chamber 33. Since a suction force toward the intake cylinder 34 is acting substantially above the center of the dust storage chamber 33, the air in the dust storage chamber 33 is attracted to the center from the bottom side where the speed of the swirl flow is weakened and rises. Dust is filtered through the first filter 35 provided at the inlet to the inlet 34 and enters the intake cylinder 34, and passes through the second filter 37 together with the air in the dust separation chamber 32 from the intake passage 26 to the electric blower 61. Sucked.

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。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。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。   The intake cylinder 34 sucks the air in the dust separation chamber 32 from the opening provided with the filter 36 on the lower side of the side peripheral surface, so that fine dust adheres to the filter 36, but it is difficult to remove it. In position. Further, among the dust accumulated in the dust storage chamber 33, the fibrous material is softly accumulated in a bulky state and occupies the dust storage volume of the dust storage chamber 33, so that the amount of dust absorption is reduced. If the volume of the dust storage chamber 33 is increased, the amount of dust absorption can be increased. However, the vacuum cleaner body 7 is increased in size, which does not meet the demand for reduction in size and weight.

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。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。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。   In order to solve the above-described problem, an outer cylinder 38 is disposed above a concentric circle with the intake cylinder 34 so as to be vertically movable. The outer cylinder 38 is provided with a dust remover 39 whose tip is in contact with the filter 36 at the lower end, and an operation lever 40 is formed on one side peripheral surface so as to extend outward in the diameter direction. Since the operation lever 40 is biased upward by the spring spring 41, the outer cylinder 38 is in the state shown in FIG. 6 when no pressure is applied to the operation lever 40.

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39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。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36面は閉じられるので、塵埃分離室32内から吸気筒34への吸気は停止される。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。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。   FIG. 8 shows a state in which the operating lever 40 is pressed. When the outer cylinder 38 is lowered by the pressing operation of the operating lever 40, the dust removing body 39 removes dust attached to the surface of the filter 36 by the lowering operation. The body 39 is scraped off and the filter 36 is cleaned. When the outer cylinder 38 is lowered to the lower end of the intake cylinder 34, the surface of the filter 36 of the intake cylinder 34 is closed, so that intake from the dust separation chamber 32 to the intake cylinder 34 is stopped. Accordingly, the intake air from the intake cylinder 34 is concentrated in the dust storage chamber 33, and all the air in the dust separation chamber 32 also flows into the dust storage chamber 33, so that the suction force from the dust storage chamber 33 to the intake cylinder 34 increases rapidly. Of the dust collected in the dust storage chamber 33, fibrous dust is light and fluffy, so if the suction force to the intake cylinder 34 increases rapidly, it is sucked under the first filter 35 as shown in the figure. , Fibrous dust collects and is compressed.

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。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。   When the pressure on the operation lever 40 is released, the operation lever 40 is pushed up by the urging of the spring spring 41 and the outer cylinder 38 is raised, so that the surface of the filter 36 of the intake cylinder 34 is opened and returns to the state shown in FIG. To do. In this state, intake air from the dust separation chamber 32 to the intake cylinder 34 is generated, so the amount of intake air from the dust storage chamber 33 to the intake cylinder 34 is reduced, and the compressed dust is adsorbed under the first filter 35. Since the suction force is reduced, the compressed dust falls and is combined with other dust on the bottom surface of the dust storage chamber 33, and the entire dust volume is reduced by the compression.

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 operation lever 40 can be performed at an arbitrary timing when the electric blower 61 is driven. However, if the operation is performed before the electric vacuum cleaner 1 starts cleaning, the filter 36 is cleaned and accumulated dust is removed. Since the surplus volume of the dust storage chamber 33 is expanded by compression, the vacuum cleaner 1 can be used in a state where the dust collection capacity is not lowered.

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33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。   A structure as shown in FIG. 9 can be applied to the configuration in which the dust in the dust chamber 33 is compressed by opening and closing the state in which the air in the dust separation chamber 32 is sucked from the intake cylinder 34 as described above. .

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。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。   In FIG. 9, a cylindrical intake cylinder 44 has a plurality of ventilation holes 44 a arranged in the circumferential direction on the side peripheral surface thereof, and filters (not shown) arranged in the axial direction. An outer cylinder 45 is arranged so as to be able to rotate on the outer peripheral surface. A plurality of openings 45 a are formed in the outer cylinder 45 so as to correspond to the vent holes 44 a, and an operation lever 46 is formed on one side peripheral surface so as to extend in the diameter direction. It is biased in the circumferential direction.

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。図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。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。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。   In the state where the operation lever 46 is not operated, as shown in FIG. 9A, the positions of the vent 44 a of the intake cylinder 44 and the opening 45 a of the outer cylinder 45 coincide with each other and the dust separation chamber 32. The air inside is taken into the intake cylinder 44 through the opening 45a and the vent 44a. As shown in FIG. 9B, when the operation lever 46 is pressed, the outer cylinder 45 is rotated to close the vent hole 44a of the intake cylinder 44 at a portion where the opening 45a is not formed. In this state, the air in the dust separation chamber 32 is not sucked into the suction cylinder 44, and only the dust storage chamber 33 is sucked into the suction cylinder 44. As shown in FIG. The light and bulky dust is sucked into the lower surface of the first filter 35 and compressed. Therefore, when the operation lever 46 is pressed with the vacuum cleaner 1 in operation, the bulky dust in the dust chamber 33 is compressed and the surplus volume of the dust chamber 33 is expanded, so that the dust collection capacity does not decrease. The vacuum cleaner 1 can be used in a state.

(第の実施形態)
図10は、第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。尚、第1、第2の考例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。
(First Embodiment)
Figure 10 is intended as dust collecting case 13 of the first embodiment showing a structure of a peripheral portion thereof, and is detachably mounted on the front side of the main body case 60. The first, the constituent elements common to configure a second ginseng Reference Example are denoted by the same reference numerals, and description thereof will be simplified.

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と、この塵埃収容室51の底面側から吸気した空気を塵埃分離室50の入口に戻して空気循環させる循環流路52とを備えて構成されている。   The dust collecting case 13 is configured to form a swirling flow of air containing the sucked dust and to separate the dust from the air, and the swirling flow from the dust separating chamber 50 flows in and is centrifuged. A dust storage chamber 51 for storing the dust, and a circulation channel 52 for circulating air by returning the air sucked from the bottom surface side of the dust storage chamber 51 to the inlet of the dust separation chamber 50.

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。流入した空気は誘導流路14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。   When the electric blower 61 is driven, the air containing the dust sucked from the suction tool 3 flows into the dust separation chamber 50 from the air inlet 20. The inflowing air is guided in the tangential direction of the substantially cylindrical dust separation chamber 50 by the guide channel 14 and the flow rate is increased by narrowing the cross-sectional area of the channel, resulting in a high-speed swirling flow. The dust flows in the downwardly inclined flow path along the inner peripheral surface, the dust in the air is centrifuged, and the separated dust flows into the dust storage chamber 51 together with a part of the air.

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。   Dust that has flowed into the dust storage chamber 51 formed in a substantially cylindrical shape along the inner peripheral wall surface accumulates from the periphery of the bottom surface of the dust storage chamber 51, and the air flows from the bottom side where the swirl flow is weakened. The fine dust is filtered by the first filter 53 and is sucked into the electric blower 61 through the second filter 55 together with the air in the dust separation chamber 50 from the intake passage 26.

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、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。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。   Among the dust accumulated in the dust storage chamber 51, the fibrous material is softly accumulated in a bulky state and occupies the dust storage volume of the dust storage chamber 51, so that the amount of dust absorption is reduced. If the volume of the dust storage chamber 51 is increased, the amount of dust absorption can be increased. However, the vacuum cleaner body 7 is increased in size, which does not meet the demand for reduction in size and weight.

この課題を解決するために、塵埃収容室51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。塵埃収容室51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。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。   In order to solve this problem, a circulation channel 52 that forms an air channel between the bottom surface side of the dust storage chamber 51 and the inlet of the dust separation chamber 50 is provided. A circulation air hole 54 provided with a filter (not shown) is formed on the bottom surface side of the dust storage chamber 51, and a part of the air in the dust storage chamber 51 flows from the circulation air hole 54 to the circulation flow path 52. Since the entrance of the dust separation chamber 50 forms a high-speed swirl flow as described above by the guide passage 14, the air in the circulation passage 52 that opens to the entrance is drawn into the dust separation chamber 50 by the negative pressure. As a result, part of the air circulates.

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。   When a part of the air flows out from the bottom surface side of the dust storage chamber 51, the dust accumulated on the bottom surface is deposited on the flow of the flowing out air, accumulated in a compressed state, and accumulated as a result of the compression. The amount decreases.

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。把手9は中空構造に形成され、塵埃収容室51の底面に設けた循環空気穴57は把手9の中空部を利用した循環流路56に連通し、循環流路56は塵埃分離室50の入口に連通して、図示するような空気の流路を形成する。   In the configuration shown in FIG. 11, the circulation channel 56 is formed in the handle 9 of the dust collecting case 13a. The handle 9 is formed in a hollow structure, and a circulation air hole 57 provided in the bottom surface of the dust storage chamber 51 communicates with a circulation channel 56 using the hollow part of the handle 9, and the circulation channel 56 is an inlet of the dust separation chamber 50. To form an air flow path as shown in the figure.

塵埃収容室51において、質量の大きい塵埃は旋回流による遠心力によって底部周囲に飛ばされて堆積し、繊維質のような質量が小さく嵩高い塵埃は旋回流と共に回転するが、旋回流の流速が弱まる底部側では中央部付近に集まりやすくなり、その位置に循環空気穴57からの吸気があると、より集中して堆積量が増し、吸気に伴って圧縮が進行する。   In the dust storage chamber 51, dust having a large mass is blown and accumulated around the bottom by centrifugal force due to the swirling flow, and dust having a small mass such as fiber rotates with the swirling flow. The weakened bottom side tends to gather near the center, and if there is intake air from the circulating air hole 57 at that position, the accumulation amount increases more and the compression proceeds with the intake air.

本発明は、広く普及し、日常多用される電気掃除機に関するもので、産業上の利用性を満足するのは勿論、繊維質のように嵩高い塵埃で塵埃収容室の容積内が占拠されて容積に比して吸塵量が低下することを防止できる   The present invention relates to a vacuum cleaner that is widely spread and frequently used every day. In addition to satisfying industrial applicability, the dust storage chamber is occupied by bulky dust such as fiber. It can prevent the amount of dust absorption from decreasing compared to the volume.
