Description

本発明は、サイクロン式の集塵装置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 collector.

近年、吸い込んだ空気を集塵容器内で旋回させることにより遠心力で比較的大きい塵埃を分離させ、集塵容器の底部に堆積させるサイクロン式の集塵装置を備えた電気掃除機が広く普及し、それに係る従来技術が特許文献１に開示されている。   In recent years, vacuum cleaners equipped with a cyclone type dust collecting device that separates relatively large dust by centrifugal force by swirling the sucked air in the dust collecting container and deposits it on the bottom of the dust collecting container have become widespread. Patent Document 1 discloses a related art related thereto.

特許文献１に記載された電気掃除機は電動送風機を内蔵した本体を備えている。被掃除面に対向する吸込口体には接続パイプが接続され、本体には可撓性のホースが接続されている。接続パイプとホースとの間であって、接続パイプの上端部にサイクロン式の集塵装置が配置されている。   The vacuum cleaner described in Patent Document 1 includes a main body with a built-in electric blower. A connection pipe is connected to the suction port facing the surface to be cleaned, and a flexible hose is connected to the main body. A cyclone type dust collector is disposed between the connection pipe and the hose at the upper end of the connection pipe.

集塵装置は上面に開口面を有する断面円形の有底筒状に形成された着脱自在の集塵容器（ダストカップ）を備えている。集塵容器の上方には集塵容器上面の開口面の箇所が嵌合するサイクロン本体が設けられている。サイクロン本体にはその周面に接続パイプに連通して接続パイプからの空気を周接線方向に流入させる流入口（空気吹出し口）が設けられている。集塵容器内では流入口から流入する空気によって旋回気流が形成される。   The dust collecting device includes a detachable dust collecting container (dust cup) formed in a bottomed cylindrical shape having a circular cross section having an opening surface on the upper surface. Above the dust collection container, a cyclone main body is provided in which a portion of the opening surface of the upper surface of the dust collection container is fitted. The cyclone main body is provided with an inflow port (air outlet) on the peripheral surface thereof for communicating with the connection pipe and allowing air from the connection pipe to flow in the circumferential tangential direction. In the dust collecting container, a swirling airflow is formed by the air flowing from the inlet.

集塵容器内には周面に気流の流出口（排気口）を開口した内筒（排気筒）が同軸に配置されている。内筒はサイクロン本体からぶら下がる形で取り付けられ、その周面の流出口にはフィルターが設けられている。サイクロン本体は電気掃除機の本体に接続されたホースに連通している。集塵装置はサイクロン本体及び内筒に対して集塵容器を着脱することができる。   An inner cylinder (exhaust cylinder) having an air flow outlet (exhaust port) opened on the peripheral surface thereof is coaxially disposed in the dust collecting container. The inner cylinder is attached so as to hang from the cyclone body, and a filter is provided at the outlet of the peripheral surface. The cyclone body communicates with a hose connected to the body of the vacuum cleaner. The dust collecting device can attach and detach the dust collecting container to the cyclone main body and the inner cylinder.

上記構成の電気掃除機において、電動送風機の駆動によって吸込口体から被掃除面上の塵埃が空気とともに吸い込まれる。吸込口体から吸い込まれた空気は接続パイプを介して流入口から集塵装置の集塵容器内に流入する。集塵容器に流入した空気は集塵容器内で旋回し、遠心力によって大きい塵埃が分離されて集塵容器の底部に堆積する。   In the vacuum cleaner having the above-described configuration, dust on the surface to be cleaned is sucked together with air from the suction port body by driving the electric blower. The air sucked from the suction port body flows into the dust collecting container of the dust collecting device from the inlet through the connection pipe. The air that has flowed into the dust collecting container swirls within the dust collecting container, and large dust is separated by centrifugal force and accumulated on the bottom of the dust collecting container.

大きい塵埃が除去された気流は流出口を介して内筒内へと流通するときに流出口のメッシュ（フィルター）によって細かい塵埃が捕集される。細かい塵埃が除去された気流はサイクロン本体、すなわち集塵装置から流出する。集塵装置から流出した空気はホース及び本体内の電動送風機を通過して外部に排気される。これにより、被掃除面の掃除を行うことができる。   When the airflow from which large dust has been removed flows into the inner cylinder through the outlet, fine dust is collected by the mesh (filter) at the outlet. The airflow from which fine dust has been removed flows out of the cyclone body, that is, the dust collector. The air flowing out from the dust collector passes through the hose and the electric blower in the main body and is exhausted to the outside. Thereby, the surface to be cleaned can be cleaned.

集塵装置から集塵容器を取り外すことにより集塵容器に堆積した塵埃を廃棄することができる。そして、集塵装置から集塵容器を取り外すときに内筒の外周面に対応する箇所に設けられた清掃手段が内筒の外側を摺動するようにして流出口のメッシュを清掃する。これにより、メッシュに付着した塵埃をメッシュ表面から掻き落として集塵容器内に集めることができる。   By removing the dust collecting container from the dust collecting device, the dust accumulated in the dust collecting container can be discarded. And when removing a dust container from a dust collector, the cleaning means provided in the location corresponding to the outer peripheral surface of an inner cylinder slides the outer side of an inner cylinder, and cleans the mesh of an outflow port. Thereby, the dust adhering to the mesh can be scraped off from the mesh surface and collected in the dust collecting container.

なお、他の従来技術においては、本体内部の電動送風機の前方にサイクロン式の集塵装置を配置した電動掃除機も存在する。   In addition, in another prior art, there exists an electric cleaner in which a cyclone type dust collector is disposed in front of the electric blower inside the main body.

しかしながら、上記従来の電気掃除機は集塵装置から集塵容器を取り外したときにリング状の清掃部が内筒のメッシュ部の最下部で停止してそこに留まる。これにより、メッシュに絡みついた髪の毛や糸屑、綿などの繊維状をなす塵埃が内筒と清掃部との間に挟まってメッシュの表面から引き離すことができず、メッシュの表面に堆積する可能性がある。その結果、集塵容器に堆積した塵埃を廃棄するときにメッシュの表面に堆積した塵埃を使用者がブラシのような清掃具や手で直接取り除く必要があり、非常に煩わしいという問題があった。   However, in the conventional vacuum cleaner, when the dust container is removed from the dust collector, the ring-shaped cleaning portion stops at the lowermost part of the mesh portion of the inner cylinder and stays there. As a result, hair, lint, and cotton-like dust entangled with the mesh cannot be separated from the surface of the mesh by being sandwiched between the inner cylinder and the cleaning unit, and may accumulate on the surface of the mesh. There is. As a result, when the dust accumulated in the dust collecting container is discarded, it is necessary for the user to directly remove the dust accumulated on the surface of the mesh with a cleaning tool such as a brush or by hand, which is very troublesome.

さらに、塵埃がメッシュの表面に堆積すると、集塵容器内の旋回気流の勢いが弱くなる可能性がある。これにより、集塵装置の集塵力が低下するという問題があった。   Furthermore, if dust accumulates on the surface of the mesh, the momentum of the swirling airflow in the dust collecting container may be weakened. Thereby, there existed a problem that the dust collection power of a dust collector fell.

本発明は、上記の点に鑑みなされたものであり、集塵容器に堆積した塵埃を廃棄するときの使用者の煩わしさを解消することができるのとともに、集塵力の向上を図ることが可能な電気掃除機を提供することを目的とする。   The present invention has been made in view of the above points, and it is possible to eliminate the troublesomeness of the user when the dust accumulated in the dust collecting container is discarded, and to improve the dust collecting power. An object is to provide a possible vacuum cleaner.

上記の課題を解決するため、本発明の電気掃除機は、上面に開口面を有する断面円形の有底筒状に形成されるとともに周面に気流の流入口が設けられた着脱自在の集塵容器と、前記集塵容器と同軸に配置されて気流の流出口を周面に開口するとともに前記流出口にメッシュが設けられた内筒と、前記内筒から径方向外側に延びる円板部と前記円板部の周縁から上下に延びる筒状部とを有するとともに前記集塵容器の内面との間に気流路を形成して前記集塵容器内を上下に仕切る仕切部材と、を備え、前記流入口から前記集塵容器に流入させた気流を旋回させて塵埃を前記集塵容器内に脱落させるサイクロン式の集塵装置を設けた電気掃除機において、前記仕切部材が前記内筒に対して着脱自在に設けられるとともに、前記内筒の外周面に沿って近接して前記仕切部材を前記内筒から取り外すときに前記内筒の外周面の箇所を摺動する清掃部を前記仕切部材に一体として設けたことを特徴としている。   In order to solve the above problems, a vacuum cleaner according to the present invention is a detachable dust collector that is formed in a bottomed cylindrical shape having a circular cross section with an opening surface on the upper surface and an airflow inlet is provided on the peripheral surface. A container, an inner cylinder that is arranged coaxially with the dust collecting container and opens an airflow outlet to the peripheral surface, and a mesh is provided at the outlet, and a disk portion that extends radially outward from the inner cylinder A partition member that has a cylindrical portion extending vertically from the periphery of the disc portion and forms an air flow path between the inner surface of the dust collecting container and partitions the dust collecting container up and down, An electric vacuum cleaner provided with a cyclone type dust collecting device that swirls an airflow flowing into the dust collecting container from an inflow port to drop the dust into the dust collecting container, wherein the partition member is disposed on the inner cylinder. Along with the outer peripheral surface of the inner cylinder is provided detachably Close to being characterized by providing as an integral cleaning unit for sliding a portion of the outer circumferential surface of the inner cylinder in the partition member when removing the partition member from the inner cylinder.

この構成によれば、仕切部材を内筒から取り外すことにより清掃部が内筒の外側を摺動して流出口のメッシュの表面を清掃する。したがって、メッシュに絡みついた髪の毛や糸屑、綿などの繊維状をなす塵埃が内筒と清掃部との間に挟まるようなことがなく、それら塵埃がメッシュの表面に堆積することが妨げられる。   According to this configuration, by removing the partition member from the inner cylinder, the cleaning unit slides on the outside of the inner cylinder and cleans the surface of the mesh at the outlet. Therefore, the dust in the form of fibers such as hair, yarn waste, and cotton entangled with the mesh is not caught between the inner cylinder and the cleaning portion, and the dust is prevented from accumulating on the surface of the mesh.

また、上記構成の電気掃除機において、前記仕切部材が前記内筒に対して着脱自在に係合するための爪部を備え、前記内筒が前記仕切部材の前記爪部を係止するために前記内筒の外周面一周にわたって連続させて形成された係止溝を備えることを特徴としている。   Further, in the vacuum cleaner having the above-described configuration, the partition member includes a claw portion that is detachably engaged with the inner cylinder, and the inner cylinder locks the claw portion of the partition member. It is characterized by comprising a locking groove formed continuously over the outer peripheral surface of the inner cylinder.

この構成によれば、内筒の周方向に関するいずれの箇所に対しても爪部を介して仕切部材が係合する。したがって、集塵容器に堆積した塵埃を廃棄するときの使用者の煩わしさがさらに解消される。   According to this structure, a partition member engages via the nail | claw part with respect to any location regarding the circumferential direction of an inner cylinder. Therefore, the user's troublesomeness when discarding the dust accumulated in the dust collecting container is further eliminated.

また、上記構成の電気掃除機において、前記仕切部材が前記清掃部を支持するために前記円板部から前記清掃部まで前記内筒の外周面に沿って延びる支柱部を備え、前記内筒が前記流出口を複数に分割する枠部を備え、前記係止溝が前記内筒の径方向に関して前記枠部に前記支柱部を重ならせる箇所で前記係止溝内における前記爪部の周方向への移動の抵抗となるストッパ部を備えることを特徴としている。   Further, in the electric vacuum cleaner having the above-described configuration, the partition member includes a column portion extending along an outer peripheral surface of the inner cylinder from the disk portion to the cleaning section in order to support the cleaning section, and the inner cylinder includes A frame portion that divides the outflow port into a plurality of portions, and a circumferential direction of the claw portion in the locking groove at a location where the locking groove overlaps the column portion with the frame portion in the radial direction of the inner cylinder It is characterized by including a stopper portion that provides resistance to movement.

この構成によれば、爪部を係止溝のストッパ部の箇所に合わせて係合させると、内筒の枠部と仕切部材の支柱部とが内筒の径方向に関して重なる。したがって、内筒の流出口と仕切部材の支柱部とが内筒の径方向に関して重ならないので、集塵装置の集塵力の低下が妨げられる。   According to this configuration, when the claw portion is engaged with the stopper portion of the locking groove and engaged, the frame portion of the inner cylinder and the support column portion of the partition member overlap in the radial direction of the inner cylinder. Therefore, since the outlet of the inner cylinder and the column portion of the partition member do not overlap with each other in the radial direction of the inner cylinder, a reduction in the dust collecting force of the dust collector is prevented.

また、上記構成の電気掃除機において、前記集塵容器の前記集塵装置への装着とともに前記仕切部材が前記集塵容器の内底面に当接して前記内筒から取り外された前記仕切部材を前記内筒に対して装着させるために前記円板部から前記集塵容器の内底面に向かって延びる突出部を備えることを特徴としている。   Further, in the vacuum cleaner having the above-described configuration, the partition member is attached to the dust collector of the dust container and the partition member comes into contact with the inner bottom surface of the dust container and is removed from the inner cylinder. In order to attach to the inner cylinder, a protruding portion extending from the disk portion toward the inner bottom surface of the dust collecting container is provided.

この構成によれば、内筒に対する仕切部材の装着が不十分であっても、集塵容器の集塵装置への装着とともに内筒に対する仕切部材の装着が完遂する。したがって、内筒に対する仕切部材の装着の不具合が解消され、集塵装置の集塵力の低下が妨げられる。   According to this configuration, even when the partition member is not sufficiently attached to the inner cylinder, the attachment of the partition member to the inner cylinder is completed together with the dust container being attached to the dust collector. Therefore, the problem of mounting the partition member on the inner cylinder is solved, and the reduction of the dust collecting power of the dust collecting device is prevented.

また、上記構成の電気掃除機において、前記清掃部が前記内筒の外周面に近接して径方向内側に前記内筒を擁するリング状で構成されていることを特徴としている。   Moreover, the vacuum cleaner of the said structure WHEREIN: The said cleaning part is comprised by the ring shape which adjoins the outer peripheral surface of the said inner cylinder, and hold | maintains the said inner cylinder in radial direction.

この構成によれば、清掃部の強度が向上する。したがって、清掃部の内筒に対する清掃能力が向上するので、繊維状をなす塵埃が流出口のメッシュの表面に堆積することを妨げる作用がより一層向上する。   According to this configuration, the strength of the cleaning unit is improved. Therefore, since the cleaning capability of the cleaning portion with respect to the inner cylinder is improved, the action of preventing the fibrous dust from accumulating on the surface of the mesh at the outlet is further improved.

本発明の構成によれば、流出口のメッシュに絡みついた髪の毛や糸屑、綿などの繊維状をなす塵埃が内筒と清掃部との間に挟まるようなことがなく、それら塵埃がメッシュ表面に堆積することが妨げられる。したがって、集塵容器に堆積した塵埃を廃棄するときの使用者の煩わしさを解消することができるのとともに、集塵力の向上を図ることが可能な電気掃除機を提供することができる。   According to the configuration of the present invention, the dust that forms fibers such as hair, lint, and cotton entangled with the mesh at the outlet is not caught between the inner cylinder and the cleaning unit, and the dust is Is prevented from depositing. Accordingly, it is possible to provide a vacuum cleaner that can eliminate the troublesomeness of the user when the dust accumulated in the dust collecting container is discarded and can improve the dust collecting power.

フィルター保持部２３は集塵装置２０の上部であって、集塵容器２２の上方に配置されている。フィルター保持部２３はプリーツフィルタ等により形成されたフィルター２３ａを保持している。フィルター２３ａは平面視円形をなして集塵容器２２と同軸に配置されている。フィルター保持部２３の上面は全体がカバー部２１によって覆われ、カバー部２１の後部に設けられた集塵装置排気口２１ｂに連通している。なお、集塵装置排気口２１ｂは集塵装置２０と電動送風機６との間に設けられたダクト１２に連通し、集塵装置２０で塵埃を除去した気流が流出する。   The filter holding unit 23 is disposed above the dust collecting container 22 and above the dust collecting device 20. The filter holding unit 23 holds a filter 23a formed by a pleated filter or the like. The filter 23 a has a circular shape in plan view and is arranged coaxially with the dust collection container 22. The entire upper surface of the filter holding part 23 is covered with the cover part 21 and communicates with a dust collector exhaust port 21 b provided at the rear part of the cover part 21. The dust collector exhaust port 21b communicates with a duct 12 provided between the dust collector 20 and the electric blower 6, and an airflow from which dust is removed by the dust collector 20 flows out.

除塵部２４はフィルター保持部２３の上面の箇所に設けられ、加振部２４ａを備えている。加振部２４ａはフィルター２３ａの上方に配置され、フィルター２３ａと同軸をなす軸線中心に回転自在である。加振部２４ａはモータ或いは手動によりフィルター２３ａの周方向に沿って回転移動しながらフィルター２３ａのプリーツの頂部に当接する。除塵部２４は加振部２４ａを回転させることにより加振部２４ａがフィルター２３ａの頂部を順次はじいてフィルター２３ａを振動させ、その表面に付着した塵埃を落として除去する。   The dust removal unit 24 is provided at a location on the upper surface of the filter holding unit 23 and includes a vibration unit 24a. The vibration unit 24a is disposed above the filter 23a, and is rotatable about an axis that is coaxial with the filter 23a. The vibration part 24a abuts on the top of the pleats of the filter 23a while rotating and moving along the circumferential direction of the filter 23a by a motor or manually. The dust removing unit 24 rotates the vibrating unit 24a so that the vibrating unit 24a sequentially repels the top of the filter 23a to vibrate the filter 23a, and removes and removes dust adhering to the surface.

内筒３０はフィルター保持部２３の下面から下方の集塵容器２２内に向かって突出する形で設けられている。内筒３０は集塵容器２２と同軸に配置され、周面に集塵容器２２内の気流の流出口３１が開口されている。集塵容器２２内で旋回する気流は流出口３１を通って集塵容器２２の外へと流出してフィルター２３ａの箇所へと至る。   The inner cylinder 30 is provided so as to protrude from the lower surface of the filter holding portion 23 into the dust collection container 22 below. The inner cylinder 30 is arranged coaxially with the dust collection container 22, and an air outlet 31 of the air flow in the dust collection container 22 is opened on the peripheral surface. The airflow swirling in the dust collection container 22 flows out of the dust collection container 22 through the outlet 31 and reaches the filter 23a.

仕切部材４０は内筒３０の外側及び下方に設けられている。仕切部材４０は内筒３０に対して着脱自在に設けられている。仕切部材４０は集塵容器２２の内面との間に気流路を形成して集塵容器２２内を上下に仕切っている。   The partition member 40 is provided outside and below the inner cylinder 30. The partition member 40 is provided detachably with respect to the inner cylinder 30. The partition member 40 forms an air flow path between the inner surface of the dust collection container 22 and partitions the inside of the dust collection container 22 up and down.

このような構成の電気掃除機１において、操作部１０のスイッチ操作により電動送風機６を駆動すると塵埃を含んだ空気が吸込口体５から吸い込まれる。吸込口体５から吸い込まれた空気は延長パイプ４及び接続ホース３を経由し、流入口２２ｂを通って集塵装置２０及び集塵容器２２に流入する。このとき、空気と一緒に吸い込まれた塵埃が旋回の遠心力によって空気流から分離され、集塵容器２２内に捕集される。   In the vacuum cleaner 1 having such a configuration, when the electric blower 6 is driven by a switch operation of the operation unit 10, air containing dust is sucked from the suction port body 5. The air sucked from the suction port body 5 flows into the dust collecting device 20 and the dust collecting container 22 through the extension pipe 4 and the connection hose 3 and through the inlet 22b. At this time, the dust sucked together with the air is separated from the air flow by the centrifugal force of rotation and collected in the dust collecting container 22.

集塵容器２２内に導かれた空気は流出口３１から流出し、内筒３０の内部を経てフィルター保持部２３を通過する。このとき、集塵容器２２で分離されなかった比較的細かい塵埃がフィルター保持部２３の空気流通方向上流側（下側）の面で捕集され、集塵容器２２に落下、或いはフィルター保持部２３表面に付着する。フィルター保持部２３を通過した空気は集塵装置排気口２１ｂを通って集塵装置２０から流出する。集塵装置２０から流出した空気はダクト１２を経由して電動送風機６を通り、排気口１１ｂを介して電気掃除機１の外部に排出される。   The air guided into the dust collection container 22 flows out from the outflow port 31 and passes through the filter holding portion 23 through the inside of the inner cylinder 30. At this time, relatively fine dust that has not been separated in the dust collection container 22 is collected on the upstream (downside) surface of the filter holding unit 23 in the air flow direction, and falls into the dust collection container 22 or the filter holding unit 23. Adhere to the surface. The air that has passed through the filter holder 23 flows out of the dust collector 20 through the dust collector exhaust port 21b. The air flowing out from the dust collector 20 passes through the electric blower 6 through the duct 12 and is discharged to the outside of the electric vacuum cleaner 1 through the exhaust port 11b.

続いて、内筒３０及び仕切部材４０の詳細な構成について、図３に加えて図４〜図８を用いて説明する。図４は内筒３０及び仕切部材４０の垂直断面側面図、図５は内筒３０及び仕切部材４０の斜視図にして、内筒３０に対して仕切部材４０を取り外した状態を示すもの、図６は内筒３０及び仕切部材４０の係合箇所を示す垂直断面側面図、図７は内筒３０の係止溝を示す水平断面部分平面図、図８は内筒３０及び仕切部材４０の斜視図にして、内筒３０に対して仕切部材４０を取り付けた状態を示すものである。   Next, detailed configurations of the inner cylinder 30 and the partition member 40 will be described with reference to FIGS. 4 to 8 in addition to FIG. 3. 4 is a vertical sectional side view of the inner cylinder 30 and the partition member 40, and FIG. 5 is a perspective view of the inner cylinder 30 and the partition member 40, showing a state in which the partition member 40 is removed from the inner cylinder 30, 6 is a vertical cross-sectional side view showing an engagement portion of the inner cylinder 30 and the partition member 40, FIG. 7 is a horizontal cross-sectional partial plan view showing a locking groove of the inner cylinder 30, and FIG. 8 is a perspective view of the inner cylinder 30 and the partition member 40. The state which attached the partition member 40 with respect to the inner cylinder 30 is shown in figure.

内筒３０は、図４及び図５に示すように流出口３１、枠部３２、メッシュ３３及び係止溝３４を備えている。   As shown in FIGS. 4 and 5, the inner cylinder 30 includes an outlet 31, a frame portion 32, a mesh 33, and a locking groove 34.

流出口３１は複数の枠部３２によって複数に分割されている。枠部３２は上下方向に延びて複数の縦長矩形の流出口３１を形成している。枠部３２は内筒３０の周方向に関して幅が比較的広い枠部３２ａと幅が比較的狭い枠部３２ｂとからなっている。幅が広い枠部３２ａは内筒３０の周方向に沿って少なくとも角度９０°ごとに４本設けられている。   The outlet 31 is divided into a plurality of frames 32. The frame portion 32 extends in the vertical direction to form a plurality of vertically long rectangular outlets 31. The frame portion 32 includes a frame portion 32 a having a relatively wide width and a frame portion 32 b having a relatively narrow width in the circumferential direction of the inner cylinder 30. Four wide frame portions 32 a are provided along the circumferential direction of the inner cylinder 30 at least every 90 °.

流出口３１には塵埃を捕集するためのメッシュ３３が設けられている。メッシュ３３は内筒３０の外周面または内周面に流出口３１を覆う形で設けられている。   The outflow port 31 is provided with a mesh 33 for collecting dust. The mesh 33 is provided on the outer peripheral surface or inner peripheral surface of the inner cylinder 30 so as to cover the outlet 31.

係止溝３４は、図４〜図６に示すように内筒３０の外周面下部に設けられている。係止溝３４は径方向内側に向かって窪んだ凹部で構成され、内筒３０の外周面一周にわたって連続させて形成されている。内筒３０に対して仕切部材４０を取り付けるとき、内筒３０の係止溝３４が仕切部材４０の後述する爪部４６を係止する。   The locking groove 34 is provided in the lower part of the outer peripheral surface of the inner cylinder 30 as shown in FIGS. The locking groove 34 is formed by a concave portion that is recessed inward in the radial direction, and is formed continuously over the entire outer peripheral surface of the inner cylinder 30. When the partition member 40 is attached to the inner cylinder 30, the locking groove 34 of the inner cylinder 30 locks a claw portion 46 described later of the partition member 40.

仕切部材４０は、図４及び図５に示すように円板部４１、筒状部４２、突出部４３、清掃部４４、支柱部４５及び爪部４６を備えている。   As shown in FIGS. 4 and 5, the partition member 40 includes a disk part 41, a cylindrical part 42, a protruding part 43, a cleaning part 44, a column part 45, and a claw part 46.

円板部４１は内筒３０の下端から径方向外側に向かって延びる円板状に形成されている。筒状部４２は円板部４１の周縁から上下に向かって延びる筒状に形成されている。   The disc portion 41 is formed in a disc shape extending from the lower end of the inner cylinder 30 toward the radially outer side. The cylindrical portion 42 is formed in a cylindrical shape extending upward and downward from the periphery of the disc portion 41.

突出部４３は内筒３０に連通して円板部４１の下面から下方に突出し、集塵容器２２の内底面に向かって延びている。仕切部材４０を内筒３０に取り付け、集塵装置２０に集塵容器２２を取り付けると、突出部４３が集塵容器２２の内底面にちょうど当接するように構成されている。すなわち、突出部４３は集塵容器２２の集塵装置２０への装着とともに仕切部材４０を集塵容器２２の内底面に当接させ、内筒３０から取り外された仕切部材４０を内筒３０に対して装着させる。   The protruding portion 43 communicates with the inner cylinder 30, protrudes downward from the lower surface of the disc portion 41, and extends toward the inner bottom surface of the dust collecting container 22. When the partition member 40 is attached to the inner cylinder 30 and the dust collecting container 22 is attached to the dust collecting device 20, the projecting portion 43 is configured to just contact the inner bottom surface of the dust collecting container 22. That is, the protrusion 43 brings the partition member 40 into contact with the inner bottom surface of the dust collection container 22 while the dust collection container 22 is attached to the dust collector 20, and the partition member 40 removed from the inner cylinder 30 is attached to the inner cylinder 30. Install it against.

このような構成の突出部４３により仕切部材４０の下方の径方向中心部に立設する断面円形の柱状部が形成され、この柱状部の周囲に気流を円滑に旋回させることができる。また、除塵部２４によるフィルター２３ａ（図２参照）の除塵でフィルター２３ａから内筒３０内に脱落した細かい塵埃は突出部４３の内側に回収される。突出部４３によって集塵容器２２内の気流への細かい塵埃の流出が防止される。   The projecting portion 43 having such a configuration forms a columnar portion having a circular cross section standing at the radially central portion below the partition member 40, and the airflow can be smoothly swung around the columnar portion. Further, the fine dust that has fallen into the inner cylinder 30 from the filter 23 a by the dust removal of the filter 23 a (see FIG. 2) by the dust removing portion 24 is collected inside the protruding portion 43. The protrusion 43 prevents fine dust from flowing into the airflow in the dust collecting container 22.

清掃部４４は円板部４１の上面から上方に向かって延びる支柱部４５によって支持され、内筒３０の外周面に沿って近接する形で構成されている。清掃部４４は内筒３０の外周面に近接して径方向内側に内筒３０を擁する例えばリング状で構成されている。清掃部４４は仕切部材４０を内筒３０から取り外すときに内筒３０の外周面の箇所を摺動する。清掃部４４の内周面に内筒３０のメッシュ３３表面に接触するブラシ状の部材を設けても良い。また、清掃部４４は内筒３０の周りを囲うように配置された複数の円弧状の部材で構成されていても良い。   The cleaning unit 44 is supported by a support column 45 that extends upward from the upper surface of the disk unit 41, and is configured to approach along the outer peripheral surface of the inner cylinder 30. The cleaning unit 44 is formed in, for example, a ring shape that is close to the outer peripheral surface of the inner cylinder 30 and holds the inner cylinder 30 radially inward. The cleaning unit 44 slides on the outer peripheral surface of the inner cylinder 30 when the partition member 40 is removed from the inner cylinder 30. A brush-like member that contacts the surface of the mesh 33 of the inner cylinder 30 may be provided on the inner peripheral surface of the cleaning unit 44. Moreover, the cleaning part 44 may be comprised with the some circular-arc-shaped member arrange | positioned so that the circumference | surroundings of the inner cylinder 30 may be enclosed.

支柱部４５は清掃部４４を支持するために円板部４１の上面から清掃部４４まで上方に向かって内筒３０の外周面に沿って延びている。支柱部４５は内筒３０の周方向に沿って角度９０°ごとに４本設けられている。そして、内筒３０に取り付けた仕切部材４０を周方向に回転させると、すべての支柱部４５各々と内筒３０の枠部３２ａとが内筒の径方向に関して重なる状態にすることができる（図８参照）。支柱部４５は内筒３０の周方向に関して枠部３２ａと幅がほぼ同じ、若しくは枠部３２ａより若干幅が狭くなっている。   The support column 45 extends along the outer peripheral surface of the inner cylinder 30 upward from the upper surface of the disc portion 41 to the cleaning unit 44 in order to support the cleaning unit 44. Four struts 45 are provided every 90 ° along the circumferential direction of the inner cylinder 30. Then, when the partition member 40 attached to the inner cylinder 30 is rotated in the circumferential direction, all the column portions 45 and the frame portion 32a of the inner cylinder 30 can be brought into an overlapping state in the radial direction of the inner cylinder (see FIG. 8). The column portion 45 is substantially the same width as the frame portion 32a in the circumferential direction of the inner cylinder 30, or slightly narrower than the frame portion 32a.

爪部４６は、図４〜図６に示すように円板部４１の上面であって内筒３０の下端外周面に対応する箇所に設けられている。爪部４６は円板部４１の上面から上方に向かって突出し、弾性変形により内筒３０の径方向、すなわち内筒３０の外周面に対して接近或いは離隔する方向に変位可能である。爪部４６は内筒３０の係止溝３４に対して所謂スナップフィット構造をなして係合し、仕切部材４０の内筒３０に対する着脱を自在にする。   As shown in FIGS. 4 to 6, the claw portion 46 is provided on the upper surface of the disc portion 41 and at a position corresponding to the outer peripheral surface of the lower end of the inner cylinder 30. The claw portion 46 protrudes upward from the upper surface of the disc portion 41 and can be displaced in a radial direction of the inner cylinder 30, that is, a direction approaching or separating from the outer peripheral surface of the inner cylinder 30 by elastic deformation. The claw portion 46 engages with the locking groove 34 of the inner cylinder 30 in a so-called snap-fit structure so that the partition member 40 can be freely attached to and detached from the inner cylinder 30.

ここで、係止溝３４は周方向に関して少なくとも１箇所に、図７に示すストッパ部３４ａを備えている。ストッパ部３４ａの周方向の両側にはストッパ部３４ａが周方向に関して爪部４６をちょうど収容可能な大きさをなすような段差３４ｂが設けられている。２箇所の段差３４ｂ各々のストッパ部３４ａ対する周方向外側には係止溝３４の内周面に対して傾斜３４ｃが形成されている。   Here, the locking groove 34 includes at least one stopper portion 34a shown in FIG. 7 in the circumferential direction. On both sides of the stopper portion 34a in the circumferential direction, there are provided steps 34b such that the stopper portion 34a has a size that can just accommodate the claw portion 46 in the circumferential direction. A slope 34c is formed with respect to the inner peripheral surface of the locking groove 34 on the outer side in the circumferential direction with respect to the stopper portion 34a of each of the two steps 34b.

これにより、ストッパ部３４ａの周方向外側で係止溝３４に係合した爪部４６をストッパ部３４ａに向かって移動させるように内筒３０に取り付けた仕切部材４０を回転させると、爪部４６が傾斜３４ｃの箇所で径方向外側に弾性変形しながら移動して段差３４ｂを越え、ストッパ部３４ａに収まる。ストッパ部３４ａはその内部に爪部４６が収まると、段差３４ｂの作用により係止溝３４内における爪部４６の周方向への移動の抵抗となる。しかしながら、爪部４６がストッパ部３４ａに収まった状態で十分な力で仕切部材４０を内筒３０に対して周方向に回転させると、爪部４６は段差３４ｂを越えて径方向外側に弾性変形してストッパ部３４ａから脱する。   Accordingly, when the partition member 40 attached to the inner cylinder 30 is rotated so that the claw portion 46 engaged with the locking groove 34 on the outer side in the circumferential direction of the stopper portion 34a is moved toward the stopper portion 34a, the claw portion 46 is rotated. Moves while elastically deforming radially outward at the position of the slope 34c, exceeds the step 34b, and fits in the stopper portion 34a. When the claw portion 46 is accommodated in the stopper portion 34a, the stopper portion 34a becomes resistance to movement of the claw portion 46 in the circumferential direction in the locking groove 34 by the action of the step 34b. However, if the partition member 40 is rotated in the circumferential direction with respect to the inner cylinder 30 with a sufficient force while the claw portion 46 is accommodated in the stopper portion 34a, the claw portion 46 elastically deforms radially outward beyond the step 34b. Then, it is detached from the stopper portion 34a.

そして、ストッパ部３４ａは内筒３０の径方向に関して内筒３０の枠部３２ａに仕切部材４０の支柱部４５を重ならせる箇所で係止溝３４内における爪部４６の周方向への移動の抵抗となる。すなわち、爪部４６を係止溝３４に係合させてストッパ部３４ａに収めると、図８に示すようにすべての支柱部４５各々と枠部３２ａとを内筒の径方向に関して重ねることができる（図８参照）。   The stopper portion 34a moves in the circumferential direction of the claw portion 46 in the locking groove 34 at a position where the column portion 32 of the partition member 40 overlaps the frame portion 32a of the inner tube 30 in the radial direction of the inner tube 30. It becomes resistance. That is, when the claw portion 46 is engaged with the locking groove 34 and accommodated in the stopper portion 34a, all the column portions 45 and the frame portion 32a can be overlapped in the radial direction of the inner cylinder as shown in FIG. (See FIG. 8).

上記のように、サイクロン式の集塵装置２０が設けられた電気掃除機１は仕切部材４０が内筒３０に対して着脱自在に設けられているとともに、内筒３０の外周面に沿って近接して仕切部材４０を内筒３０から取り外すときに内筒３０の外周面の箇所を摺動する清掃部４４が仕切部材４０に一体として設けられている。これにより、仕切部材４０を内筒３０から取り外すことにより清掃部４４が内筒３３の外側を摺動して流出口３１のメッシュ３３の表面を清掃する。したがって、メッシュ３３に絡みついた髪の毛や糸屑、綿などの繊維状をなす塵埃が内筒３０と清掃部４４との間に挟まるようなことがなく、それら塵埃がメッシュ３３の表面に堆積することを妨げることができる。その結果、電気掃除機１は集塵容器２２に堆積した塵埃を廃棄するときにメッシュ３３の表面に堆積した塵埃を使用者が直接取り除く必要がなく、煩わしさを解消することが可能である。   As described above, in the vacuum cleaner 1 provided with the cyclone type dust collecting device 20, the partition member 40 is provided detachably with respect to the inner cylinder 30 and is close to the outer peripheral surface of the inner cylinder 30. Then, when the partition member 40 is removed from the inner cylinder 30, a cleaning portion 44 that slides on the outer peripheral surface of the inner cylinder 30 is provided integrally with the partition member 40. Thereby, by removing the partition member 40 from the inner cylinder 30, the cleaning unit 44 slides outside the inner cylinder 33 to clean the surface of the mesh 33 of the outlet 31. Therefore, the dust that forms fibers such as hair, lint, and cotton entangled with the mesh 33 does not get caught between the inner cylinder 30 and the cleaning unit 44, and the dust accumulates on the surface of the mesh 33. Can be disturbed. As a result, when the vacuum cleaner 1 discards the dust accumulated in the dust collecting container 22, it is not necessary for the user to directly remove the dust accumulated on the surface of the mesh 33, and the troublesomeness can be eliminated.

また、電気掃除機１は仕切部材４０が内筒３０に対して着脱自在に係合するための爪部４６を備え、内筒３０が仕切部材４０の爪部４６を係止するために内筒３０の外周面一周にわたって連続させて形成された係止溝３４を備えているので、内筒３０の周方向に関するいずれの箇所に対しても爪部４６を介して仕切部材４０が係合する。したがって、電気掃除機１は集塵容器２２に堆積した塵埃を廃棄するときの使用者の煩わしさをさらに解消することが可能である。   Further, the vacuum cleaner 1 includes a claw portion 46 for the partition member 40 to be detachably engaged with the inner cylinder 30, and the inner cylinder 30 is configured to lock the claw portion 46 of the partition member 40. Since the locking groove 34 formed continuously over the entire circumference of the outer peripheral surface 30 is provided, the partition member 40 engages with any portion in the circumferential direction of the inner cylinder 30 via the claw portion 46. Therefore, the vacuum cleaner 1 can further eliminate the troublesomeness of the user when the dust accumulated in the dust collecting container 22 is discarded.

また、電気掃除機１は仕切部材４０が清掃部４４を支持するために内筒の外周面に沿って延びる支柱部４５を備え、内筒３０が流出口３１を複数に分割する枠部３２ａを備えている。そして、係止溝３４が内筒３０の径方向に関して枠部３２ａに支柱部４５を重ならせる箇所で係止溝３４内における爪部４６の周方向への移動の抵抗となるストッパ部３４ａを備えているので、爪部４６を係止溝３４のストッパ部３４ａの箇所に合わせて係合させると、内筒３０の枠部３２ａと仕切部材４０の支柱部４５とが内筒３０の径方向に関して重なる。したがって、電気掃除機１は内筒３０の流出口３１と仕切部材４０の支柱部４５とが内筒３０の径方向に関して重ならないようにすることができ、集塵装置２０の集塵力の低下を妨げることができる。   Further, the vacuum cleaner 1 includes a column portion 45 that extends along the outer peripheral surface of the inner cylinder so that the partition member 40 supports the cleaning portion 44, and the inner cylinder 30 includes a frame portion 32 a that divides the outlet 31. I have. A stopper portion 34a that serves as a resistance to movement of the claw portion 46 in the circumferential direction in the locking groove 34 at a position where the locking groove 34 overlaps the column portion 45a with the frame portion 32a in the radial direction of the inner cylinder 30 is provided. Since the claw portion 46 is engaged with the position of the stopper portion 34 a of the locking groove 34, the frame portion 32 a of the inner cylinder 30 and the column portion 45 of the partition member 40 are in the radial direction of the inner cylinder 30. Overlapping with respect to. Therefore, the vacuum cleaner 1 can prevent the outflow port 31 of the inner cylinder 30 and the column part 45 of the partition member 40 from overlapping with respect to the radial direction of the inner cylinder 30, and the dust collecting power of the dust collector 20 is reduced. Can be disturbed.

また、電気掃除機１は集塵容器２２の集塵装置２０への装着とともに仕切部材４０が集塵容器２２の内底面に当接して内筒３０から取り外された仕切部材４０を内筒３０に対して装着させるために円板部４１から集塵容器２２の内底面に向かって延びる突出部４３を備えている。これにより、内筒３０に対する仕切部材４０の装着が不十分であっても、集塵容器２２の集塵装置２０への装着とともに内筒３０に対する仕切部材４０の装着が完遂する。したがって、電気掃除機１は内筒３０に対する仕切部材４０の装着の不具合を解消することができ、集塵装置２０の集塵力の低下を妨げることが可能である。   In addition, the vacuum cleaner 1 attaches the partition member 40 to the inner cylinder 30, which is detached from the inner cylinder 30 by the partition member 40 coming into contact with the inner bottom surface of the dust container 22 as the dust collector 22 is attached to the dust collector 20. In order to be mounted, a projecting portion 43 extending from the disc portion 41 toward the inner bottom surface of the dust collecting container 22 is provided. Thereby, even if the mounting of the partition member 40 to the inner cylinder 30 is insufficient, the mounting of the partition member 40 to the inner cylinder 30 is completed together with the mounting of the dust collecting container 22 to the dust collector 20. Therefore, the vacuum cleaner 1 can solve the problem of mounting the partition member 40 on the inner cylinder 30, and can prevent a decrease in the dust collecting power of the dust collecting device 20.

さらに、電気掃除機１は清掃部４４が内筒３０の外周面に近接して径方向内側に内筒３０を擁するリング状で構成されているので、清掃部４４の強度が向上する。したがって、清掃部４４の内筒３０に対する清掃能力を向上させることができるので、繊維状をなす塵埃が流出口３１のメッシュ３３の表面に堆積することを妨げる作用をより一層向上させることが可能である。   Furthermore, since the cleaning part 44 is comprised in the ring shape which hold | maintains the inner cylinder 30 to radial direction inner side in the vacuum cleaner 1 near the outer peripheral surface of the inner cylinder 30, the intensity | strength of the cleaning part 44 improves. Therefore, since the cleaning capability of the cleaning unit 44 with respect to the inner cylinder 30 can be improved, it is possible to further improve the action of preventing the fibrous dust from accumulating on the surface of the mesh 33 of the outlet 31. is there.

そして、本発明の上記実施形態の構成によれば、流出口３１のメッシュ３３に絡みついた髪の毛や糸屑、綿などの繊維状をなす塵埃が内筒３３と清掃部４４との間に挟まるようなことがなく、それら塵埃がメッシュ３３表面に堆積することが妨げられる。したがって、集塵容器２２に堆積した塵埃を廃棄するときの使用者の煩わしさを解消することができるのとともに、集塵力の向上を図ることが可能な電気掃除機１を提供することができる。   And according to the structure of the said embodiment of this invention, the dust which makes | forms fibrous forms, such as the hair, the thread waste, and cotton which were entangled with the mesh 33 of the outflow port 31, is pinched | interposed between the inner cylinder 33 and the cleaning part 44. This prevents the dust from accumulating on the surface of the mesh 33. Therefore, it is possible to provide the vacuum cleaner 1 that can eliminate the troublesomeness of the user when the dust accumulated in the dust collecting container 22 is discarded and can improve the dust collecting power. .

以上、本発明の実施形態につき説明したが、本発明の範囲はこれに限定されるものではなく、発明の主旨を逸脱しない範囲で種々の変更を加えて実施することができる。   Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.
