【０００１】
【発明の属する技術分野】
本発明は真空掃除機に関し、より詳しくは、吸込みブラシを通して流入される埃及び汚物を含む空気に対し旋回気流を形成することにより、遠心力によって旋回気流から埃及び汚物を分離収去する真空掃除機用サイクロン集塵装置に関する。
【０００２】
【従来の技術】
図１及び図２では、前記のような真空掃除機用サイクロン集塵装置の一例が概略的に示されている。
【０００３】
図１及び図２において、図面符号１００はサイクロン集塵装置、２００は掃除機本体、３００は吸込みブラシであり、図面符号１０、２０、及び３０は各々サイクロン集塵装置１００を構成するサイクロンボディー、汚物収去筒、及びグリルである。
【０００４】
図１及び図２に示したように、サイクロンボディー１０は、空気流入管１１と空気排出管１２とを備える。空気流入管１１は、サイクロンボディー１０の一側壁に設けられた空気流出口（図示せず）に連結設置される。この空気流入管１１は、サイクロン集塵装置１００を掃除機本体２００に取付けるとき、掃除機本体２００で吸込みブラシ３００の吸込み口（図示せず）と連通するように形成された空気流入路２１０に連結される。また、空気排出管１２は、サイクロンボディー１０の上面に備えられた空気排出口（図示せず）に連結設置される。この空気排出管１２は、サイクロン集塵装置１００を掃除機本体２００に取付けるとき、掃除機本体２００で吸込みブラシ３００のモーター駆動室３１０と連通するように形成された空気排出路２２０に連結される。よって、吸込みブラシ３００を通して流入される埃及び汚物を含む空気は、掃除機本体２００の空気流入路２１０及び空気流入管１１を通ってサイクロンボディー１０内へ接線方向に流入される。これにより、サイクロンボディー１０には旋回気流が形成され、その旋回気流に含まれた埃および汚物は遠心力によって分離され、浄化された空気は空気排出管１２、掃除機本体２００の空気排出路２２０、及びモーター駆動室３１０を通って外部へ排出される。
【０００５】
汚物収去筒２０は、サイクロンボディー１０の下部に着脱自在に結合され、サイクロンボディー１０の旋回気流によって空気から遠心分離される埃及び汚物を収去する。
【０００６】
グリル３０は、サイクロンボディー１０内部の空気排出管１２の入口に設けられ、旋回気流から分離された埃及び汚物が空気排出管１２を通って逆流しないようにする。また、グリル３０は、グリルボディー３１及びグリルボディー３１の外周面に空気排出管１２と連通するように配置された多数の流路３２とを備える。
【０００７】
このように構成された一般的なサイクロン集塵装置では、サイクロンボディー１０の空気流入管１１及び空気排出管１２が、それぞれ掃除機本体２００の空気流入路２１０及び空気排出路２２０に連結されるように掃除機本体２００に取付けられる。
【０００８】
掃除を開始すると、モーター駆動室３１０のモーターが駆動するにつれ、吸込みブラシ３００で吸込み力が発生する。その吸込み力によって被掃除面の埃及び汚物を含む空気が、吸込みブラシ３００、空気流入路２１０、及び空気流入管１１を通ってサイクロンボディー１０内へ流入される。このとき、流入される空気は、空気流入管１１によってサイクロンボディー１０の内周に沿って斜線方向にガイドされて旋回気流を形成し、これにより空気中に含まれた埃及び汚物が遠心力によって分離され汚物収去筒２０に収去される。また、浄化された空気は、グリル３０の流路３２、空気排出管１２、空気排出路２２０、及びモーター駆動室３１０を通って外部へ排出される。
【０００９】
【発明が解決しようとする課題】
しかし、前記のような一般的なサイクロン集塵装置は、グリル３０の流路３２を通って空気が排出される過程で、収去された埃が前記空気と共に排出される埃の逆流現象が発生するので、掃除の効率が低減するという問題がある。
【００１０】
よって、本発明の目的は、前記のような問題を解決するために、グリルを回転させることにより、グリルの流路を通して埃が逆流することを最小化できる真空掃除機用サイクロン集塵装置を提供することにある。
【００１１】
【課題を解決するための手段】
上記の目的を果たすための本発明の真空掃除機用サイクロン集塵装置は、空気流入口及び空気排出口とを備え、前記空気流入口を通して流入される埃及び汚物を含む空気に対し旋回気流を形成するサイクロンボディーと；前記サイクロンボディー内の旋回気流によって空気から遠心分離される埃及び汚物を収去するように前記サイクロンボディーに着脱自在に結合される汚物収去筒と；空気から分離された前記埃及び汚物が前記空気排出口を通して逆流しないように前記サイクロンボディー内部の前記空気排出口に設けられるグリル；及び前記サイクロンボディー内の旋回気流によって前記グリルが回転するように前記グリルを支持するグリル回転支持手段とを含む。
【００１２】
前記サイクロンボディーは、前記空気流入口が形成された側部面及び前記空気排出口が形成された上部面とを備えた円筒形本体部と、該円筒形本体部の上部面に着脱自在に結合されるカバー部とを備える。前記空気流入口には掃除機本体の空気流入路に連結される空気流入管が設けられ、前記カバー部の略中央部には掃除機本体の空気排出路に連結される空気排出管が設けられる。
【００１３】
前記円筒形本体部と前記カバー部は、その結合面において互いに対応するように形成された螺旋形結合構造によって着脱自在に結合される。
【００１４】
前記グリルは、グリルボディーと；前記グリルボディーの外周面に前記空気排出口と通る流路が形成されるように所定の角度傾斜して配置された多数の流路部材とを備えてなる。
【００１５】
本発明の望ましい実施の形態において、前記グリルは、グリルボディーの下部に設けられる汚物遮断部材；を備えられ得る。
【００１６】
前記グリル回転支持手段は、前記円筒形本体部の空気排出口の中央に位置するように空気排出口の内壁面から突出した多数のリブによって支持された支持部材；及び前記支持部材に、一端は軸受の介在下回転自在に支持され、多端は前記グリルを貫通してグリル下部にてスクリュによってグリルに固定された回転部材とを備える。
【００１７】
本発明の望ましい実施の形態において、真空掃除機用サイクロン集塵装置は、前記円筒形本体部の上部面と前記カバー部との間に、微細埃をフィルタするための微細埃用フィルタ組立体が配置される。
【００１８】
前記微細埃用フィルタ組立体は、微細埃用フィルタと；前記微細埃用フィルタを受容して支持し、格子構造の下部面を有するフィルタフレームとから成り得る。
【００１９】
更に、前記円筒形本体部の上部面は、その外側から内側へ下向傾斜して形成されることが望ましい。
【００２０】
【発明の実施の形態】
本発明の前記のような目的及び他の長所は添付した図面に基づいて本発明の望ましい実施の形態を詳述することにより明らかになる。
【００２１】
図３及び図４に示したように、本発明の一実施の形態による真空掃除機用サイクロン集塵装置は、サイクロンボディー５０、汚物収去筒６０、グリル７０、及びグリル回転支持手段８０とを含む。
【００２２】
サイクロンボディー５０は、円筒形本体部５１と、円筒形本体部５１に着脱自在に結合するカバー部５２とを備える。円筒形本体部５１は側部面５１ａ及び上部面５１ｂとを備え、側部面５１ａの一側には空気流入口が形成され、上部面５１ｂには略中央部に空気排出口が形成される。また、前記空気流入口には掃除機本体２００の空気流入口２１０（図５参照）に連結される空気流入管５３が連結設置され、カバー部５２の略中央部には掃除機本体２００の空気排出路２２０（図５参照）に連結される空気排出管５４が連結設置される。一方、円筒形本体部５１とカバー部５２は、その結合面において互いに対応するように形成された螺旋形又は凹凸部のような結合構造によって着脱自在に結合される。
【００２３】
よって、掃除時の吸込みブラシ３００（図５参照）を通して流入される埃及び汚物を含む空気は、空気流入路２１０及び空気流入管５３を通ってサイクロンボディー５０の内部へ接線方向に流入される。これにより、サイクロンボディー５０で旋回気流が形成され、その旋回気流に含まれた埃及び汚物は、遠心力によって空気から分離され、浄化された空気は、空気排出管５４、空気排出路２２０、及びモーター駆動室３１０を通って外部へ排出される。
【００２４】
汚物収去筒６０は、サイクロンボディー５０で旋回気流によって空気から分離される埃及び汚物を収去するようにサイクロンボディー５０の下部に着脱自在に結合される。この汚物収去筒６０には、取り扱いを容易にするためのハンドルなどが設けられ得、汚物収去筒６０に汚物が一杯溜まると、汚物収去筒６０のみを分離して内部の汚物を捨てることができる。
【００２５】
グリル７０は、サイクロンボディー５０内部の空気排出口に設けられ、前記旋回気流から分離された埃及び汚物が前記空気排出口へ逆流しないようにする。このようなグリル７０は、グリルボディー７１及びグリルボディー７１の外周面に前記空気排出口と連通する多数の流路を形成するように配置される流路部材７２とを備える。ここで、流路部材７２は所定の角度傾斜して配置され、グリル７０は後述するグリル回転支持手段８０によってサイクロンボディー５０の内部で回転自在に備えられる。
【００２６】
グリル回転支持手段８０は、支持部材８１と回転部材８２とを備える。支持部材８１は、円筒形本体部５１の空気排出口の中央に位置するよう設置されるが、前記空気排出口の内壁面から突出した多数のリブ８１ａによって支持されるように設置される。また、回転部材８２は、支持部材８１に一端は軸受８３の介在下回転自在に支持され、多端はグリル７０を貫通してグリル７０の下部でスクリュ８４によってグリル７０に固定される。よって、サイクロンボディー５０の内部で形成される旋回気流によってグリル７０は回転部材８２と共に支持部材８１を中心に回転し、このようにグリル７０が回転するため、グリル７０の流路を通した埃及び汚物の逆流が生じにくくなる。
【００２７】
一方、本発明の真空掃除機用サイクロン集塵装置では、グリル７０が、グリルボディー７１、グリルボディー７１の外周面に前記空気排出口と通る流路が形成されるように所定の角度傾斜して配置された多数の流路部材７２、及びグリルボディー７１の下部に設けられる汚物遮断部材７３とを備えるように構成され得る。
【００２８】
汚物遮断部材７３は、グリルボディー７１の下端部から下側のほど直径が段々大きくなる下部拡張形（円錐形）に形成され、それにより、汚物収去筒６０に収去された汚物が上昇気流によって共に上昇しても、汚物遮断部材７３にぶつかってそれ以上上昇せず、汚物収去筒６０に落ちて収去される。
【００２９】
また、本発明の真空掃除機用サイクロン集塵装置は、サイクロンボディー５０の円筒形本体部５１とカバー部５２との間に介在され、グリル７０によって分離され切っていない微細な埃を２次フィルタする微細埃用フィルタ組立体９０を備える。
【００３０】
微細埃用フィルタ組立体９０は、スポンジなどのような微細埃用フィルタ９１と、微細埃用フィルタ９１を受容して支持し、かつ格子構造の下部面を有するフィルタクレーム９２とから構成される。このような微細埃用フィルタ組立体９０によりグリル７０を通過した微細埃が外部へ排出されずにフィルタされる。ここで、微細埃用フィルタ組立体９０によってフィルタされる微細埃が、円筒形本体部５１の上部面５１ｂと微細埃用フィルタ組立体９０との間に停滞しないでグリル７０を通してその下部へ降下するように、上部面５１ｂは、その外側から内側へ下向傾斜して形成されることが望ましい。
【００３１】
このように構成された本発明の真空掃除機用サイクロン集塵装置は、図５に示すように、サイクロンボディー５０の空気流入管５３及び空気排出管５４が、それぞれ掃除機本体２００の空気流入路２１０及び空気排出路２２０に連結されるように掃除機本体２００に取付けられる。
【００３２】
掃除を開始すると、モーター駆動室３１０のモーターが駆動するにつれ、吸込みブラシ３００で吸込み力が発生する。この吸込み力によって被掃除面の埃及び汚物を含む空気が、吸込みブラシ３００、空気流入路２１０、及び空気流入管５３を通ってサイクロンボディー５０内へ流入される。このとき、流入される空気は、空気流入管５３によってサイクロンボディー５０の内周に沿って斜線方向にガイドされ旋回気流を形成し、これにより空気中に含まれた埃及び汚物は遠心力によって分離され汚物収去筒６０に収去される。また、浄化された空気は、グリル７０の流路、空気排出管５４、空気排出路２２０、及びモーター駆動室３１０を通って外部へ排出される。このとき、グリル７０が本発明の特徴である、前記旋回気流によって回転するので、グリル７０の流路を通して埃及び汚物が排出される、いわば埃逆流現象は殆ど生じず、更にグリル７０で分離され切っていない微細埃がグリル７０の流路を通して排出されるとしても微細埃用フィルタ組立体９０（図４参照）によって２次フィルタされるので、集塵性能が大幅に向上できる。
【００３３】
【発明の効果】
以上で説明したように、本発明によると、掃除するときに空気中に含まれた埃及び汚物が遠心力によって分離されると同時に、埃及び汚物の逆流を防止するグリルが回転するため、グリルの流路を通した埃及び汚物の逆流が生じにくいので、埃及び汚物の逆流現象が減少する。
【００３４】
また、グリルの流路を通して微細埃が逆流する場合でも、微細埃用フィルタ組立体によって２次フィルタされるので、集塵性能が向上し、よって掃除効率も高まる。
【００３５】
つまり、本発明では、使用者の立場から判断しても非常に満足してもらえる真空掃除機を提供できるので、製品の競争力も向上できる。
【００３６】
本発明は、前述した特定の望ましい実施例に限らず、請求の範囲で請求する本発明の要旨を逸脱せず当該発明の属する技術分野において通常の知識を有する者なら何人も多様な変形実施が可能であることは勿論、そのような変形は記載された請求の範囲内にある。

[0024]
The waste collecting cylinder 60 is detachably coupled to a lower portion of the cyclone body 50 so as to collect dust and dirt separated from the air by the swirling airflow in the cyclone body 50. The waste collection tube 60 may be provided with a handle or the like for facilitating handling. When the waste collection tube 60 is full of waste, only the waste collection tube 60 is separated and the internal waste is discarded. be able to.
[0025]
The grill 70 is provided at an air outlet inside the cyclone body 50 to prevent dust and dirt separated from the swirling airflow from flowing back to the air outlet. The grill 70 includes a grill body 71 and a flow path member 72 disposed on an outer peripheral surface of the grill body 71 so as to form a plurality of flow paths communicating with the air outlet. Here, the flow path member 72 is arranged to be inclined at a predetermined angle, and the grill 70 is rotatably provided inside the cyclone body 50 by grill rotation support means 80 described later.
[0026]
The grill rotation support means 80 includes a support member 81 and a rotation member 82. The support member 81 is installed at the center of the air outlet of the cylindrical main body 51, and is installed so as to be supported by a number of ribs 81a protruding from the inner wall surface of the air outlet. One end of the rotating member 82 is rotatably supported by the support member 81 under the intervention of a bearing 83, and the other end thereof passes through the grill 70 and is fixed to the grill 70 by a screw 84 below the grill 70. Therefore, the grill 70 rotates around the support member 81 together with the rotating member 82 by the swirling airflow formed inside the cyclone body 50, and thus the grill 70 rotates, so that the dust and the dust passing through the flow path of the grill 70 are removed. Backflow of filth is less likely to occur.
[0027]
On the other hand, in the cyclone dust collecting apparatus for a vacuum cleaner according to the present invention, the grill 70 is inclined at a predetermined angle such that a flow path passing through the air discharge port is formed on the outer surface of the grill body 71 and the grill body 71. It may be configured to include a number of arranged flow path members 72 and a dirt blocking member 73 provided below the grill body 71.
[0028]
The dirt blocking member 73 is formed in a lower expanded shape (conical shape) in which the diameter is gradually increased from the lower end of the grill body 71 to the lower side, so that the dirt collected in the dirt collecting cylinder 60 has a rising airflow. Even if they rise together, they fall against the waste blocking member 60 and fall and are not removed anymore.
[0029]
In addition, the cyclone dust collecting apparatus for a vacuum cleaner according to the present invention is provided between the cylindrical main body 51 and the cover 52 of the cyclone body 50, and filters the fine dust which is not separated and cut by the grill 70. And a fine dust filter assembly 90 to be used.
[0030]
The fine dust filter assembly 90 includes a fine dust filter 91 such as a sponge, and a filter claim 92 that receives and supports the fine dust filter 91 and has a lower surface of a lattice structure. The fine dust passing through the grill 70 is filtered by the fine dust filter assembly 90 without being discharged to the outside. Here, the fine dust filtered by the fine dust filter assembly 90 does not stay between the upper surface 51b of the cylindrical main body 51 and the fine dust filter assembly 90 and descends to the lower portion through the grill 70. As described above, it is desirable that the upper surface 51b is formed to be inclined downward from the outside to the inside.
[0031]
As shown in FIG. 5, the cyclone dust collecting apparatus for a vacuum cleaner according to the present invention is configured such that the air inlet pipe 53 and the air outlet pipe 54 of the cyclone body 50 are connected to the air inlet path of the cleaner body 200, respectively. The cleaner 210 is attached to the cleaner body 200 so as to be connected to the cleaner 210 and the air discharge passage 220.
[0032]
When the cleaning is started, a suction force is generated by the suction brush 300 as the motor of the motor drive chamber 310 is driven. Due to the suction force, air containing dust and dirt on the surface to be cleaned flows into the cyclone body 50 through the suction brush 300, the air inflow path 210, and the air inflow pipe 53. At this time, the inflowing air is guided obliquely along the inner circumference of the cyclone body 50 by the air inflow pipe 53 to form a swirling airflow, whereby dust and dirt contained in the air are separated by centrifugal force. Then, the waste is collected in the waste collection cylinder 60. The purified air is discharged to the outside through the flow path of the grill 70, the air discharge pipe 54, the air discharge path 220, and the motor drive chamber 310. At this time, since the grill 70 is rotated by the swirling airflow, which is a feature of the present invention, dust and dirt are discharged through the flow path of the grill 70, so that the dust backflow phenomenon hardly occurs. Even if the uncut fine dust is discharged through the flow path of the grill 70, the fine dust is assembled by the second filter by the fine dust filter assembly 90 (see FIG. 4), so that the dust collecting performance can be greatly improved.
[0033]
【The invention's effect】
As described above, according to the present invention, when cleaning, dust and dirt contained in the air are separated by centrifugal force, and at the same time, the grill for preventing backflow of dust and dirt is rotated. Since the backflow of dust and dirt through the flow path is unlikely to occur, the backflow phenomenon of dust and dirt is reduced.
[0034]
Further, even when the fine dust flows backward through the flow passage of the grill, the dust is filtered by the secondary filter assembly, so that the dust collecting performance is improved and the cleaning efficiency is also improved.
[0035]
That is, according to the present invention, a vacuum cleaner that can be very satisfied even from the viewpoint of the user can be provided, so that the competitiveness of the product can be improved.
[0036]
