【発明の属する技術分野】
本発明は電気掃除機に関する。さらに詳しくは、ごみがサイクロン部から集塵部へ円滑に流れることができるとともにフィルタ部の目詰まりを防止することができる電気掃除機に関する。
【０００２】
【従来の技術】
従来より、サイクロン集塵器にフィルタ部を設け、サイクロン部で塵埃などを分離した空気をフィルタ部を介して電動送風機側へ流す電気掃除機が知られている。
【０００３】
たとえば、従来の電気掃除機として、電動送風機および該電動送風機の吸気側に接続されたサイクロン集塵器を備え、サイクロン集塵器内部には、傘状の仕切板をもつ中筒が取り付けられ、仕切板によって、塵埃を空気と分離するサイクロン部と集塵部とが隔てられた電気掃除機が知られている（たとえば、特許文献１参照）。

【特許文献１】
特開２００２−１４３０５２号公報
【０００５】
【発明が解決しようとする課題】
しかし、従来のサイクロン式の電気掃除機は、サイクロン部において旋回流を利用して塵埃と空気とを分離しており、砂などの比重の重いごみを分離する場合にはその分離特性を充分発揮することができるが、比重が軽いごみや髪の毛などの長いごみに対する分離効果がわるいという問題がある。たとえば、サイクロン部で分離されなかった軽いごみや長いごみは、中筒のフィルタ部に貼り付いてとどまりやすく、または中筒に巻きついたりする。そして、その影響で電動送風機の吸気側に設けられたフィルタも目詰まりしやすくなるなどの問題もある。
【０００６】
本発明はかかる問題を解消するためになされたものであり、ごみがサイクロン部から集塵部へ円滑に流れることができるとともにフィルタ部の目詰まりを防止することができる電気掃除機を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明の電気掃除機は、電動送風機および該電動送風機の吸気側に接続されたサイクロン集塵器を備え、前記サイクロン集塵器内部には、傘状の仕切板をもつ中筒が取り付けられ、該仕切板によって、塵埃を空気と分離するサイクロン部と集塵部とが隔てられた電気掃除機であって、
前記中筒の前記サイクロン部内部に延びる部分には、フィルタ部が配設され、該フィルタ部が略円錐状に傾斜した形状を呈してなることを特徴としている。
【０００８】
前記中筒の軸方向に対する前記フィルタ部の傾斜角度が、１５〜６０度程度であるのが好ましい。
【０００９】
前記中筒の軸方向に対する前記フィルタ部の傾斜角度が、２０〜４０度程度であるのが好ましい。
【００１０】
さらに前記仕切板の少なくとも前記サイクロン部側に向いている部分が略円錐状に傾斜した形状を呈してなるのが好ましい。
【００１１】
前記仕切板のサイクロン部側に向いている部分の前記中筒の軸方向に対する傾斜角度が、前記フィルタ部の前記中筒の軸方向に対する傾斜角度以上であるのが好ましい。
【００１２】
【発明の実施の形態】
つぎに図面を参照しながら本発明の電気掃除機をさらに詳細に説明する。図１は本発明の電気掃除機の一実施の形態を示す断面説明図、図２は図１のサイクロン集塵器の断面説明図、図３は図１のサイクロン集塵器のＩＩＩ−ＩＩＩ線断面図、図４は本発明の電気掃除機の他の実施の形態を示す丸孔タイプのフィルタ部を備えたサイクロン集塵器の断面説明図および図５は本発明の電気掃除機の比較例である円筒状のフィルタ部および平板状の仕切板を有するサイクロン集塵器の断面説明図である。
【００１３】
図１〜３に示される電気掃除機は、上面に取っ手３が設けられた掃除機の上ケース１と下面に移動用前車輪４および後車輪５が設けられた掃除機の下ケース２とからなる筐体内部に、電池６、下ケース２より直立せしめた壁と緩衝体８を介在して設置されたファンとモータとからなる電動送風機７、およびパッキン１４を介在して着脱自在に設けられたサイクロン集塵器９を収納したものである。なお、サイクロン集塵器９は、掃除機本体と一体形成してもよい。
【００１４】
サイクロン集塵器９は、サイクロン部９ａ内部で発生する旋回流の回転軸がほぼ水平方向に延びるように横置きに配置されている。すなわち、サイクロン集塵器９内部には、傘状の仕切板１１ａをもつ中筒１１が水平方向に取り付けられている。この仕切板１１ａによって、サイクロン集塵器９の内部空間は、塵埃を空気と分離するサイクロン部９ａおよび集塵部９ｂの２つの空間に分けられる。
【００１５】
サイクロン集塵器９には、本発明のフィルタ部に相当する１次メッシュフィルタ１２、および追加の２次フィルタ１３が配設されている。１次メッシュフィルタ１２は、中筒１１のサイクロン部９ａ内部に延びる部分に形成された導入口１１ｂに配設され、サイクロン部９ａ内部で浄化された空気をろ過することができる。
【００１６】
本実施の形態では、図２に示されるように、１次メッシュフィルタ１２が、略円錐状に傾斜した形状を呈しているため、サイクロン部９ａ内部で空気と分離されなかった軽いごみや長いごみなども、１次メッシュフィルタ１２の外周面でとどまりにくいため、円滑に集塵部９へ流れることができるとともにフィルタの目詰まりがなくなる。
【００１７】
中筒１１の軸方向に対する１次メッシュフィルタ１２の傾斜角度θ１は、１５〜６０度程度、好ましくは２０〜４０度程度であれば、サイクロン部９ａから集塵部９ｂへのごみの円滑な流入とともにフィルタの目詰まり防止という効果を発揮することができ、その一方で傾斜角度θ１が大きくなりすぎることによって吸込性能に影響を与えることもない。
【００１８】
さらに、本実施の形態では、仕切板１１ａの少なくともサイクロン部９ａ側に向いている部分も略円錐状に傾斜した形状を呈しており、前述の１次メッシュフィルタ１２の傾斜面と仕切板１１ａのサイクロン部９ａ側の傾斜面とがなめらかに連結されているため、本実施の形態の電気掃除機では、サイクロン部９ａ内部に吹き溜まりが生じることなく、さらにごみをサイクロン部９ａから集塵部９ｂへ円滑に流入させることができる。
【００１９】
とくに、仕切板１１ａのサイクロン部９ａ側に向いている部分の中筒１１の軸方向に対する傾斜角度θ２が、１次メッシュフィルタ１２の中筒１１の軸方向に対する傾斜角度θ１とほぼ同じ（すなわち同一平面になる）かそれ以上の角度をなしている（すなわち仕切板１１ａの根元部分がサイクロン部９ａ内部に張り出す）ようにすれば、サイクロン部９ａ内部には吹き溜まりは全く発生しなくなるのでさらに好ましい。
【００２０】
仕切板１１ａの傾斜角度θ２も、１次メッシュフィルタ１２の傾斜角度θ１の範囲（１５〜６０度程度、好ましくは２０〜４０度程度）から適宜選定すればよい。
【００２１】
ここで、本発明の比較例である図５に示される１次メッシュフィルタ１２の円周面と平板状の仕切り板１１ａとが直交配置された場合においては、サイクロン部９ａ内部の仕切板１１ａの根元部分周辺において吹き溜まりＡができるため、塵埃などの軽いごみや髪の毛などの長いごみは、吹き溜まりＡで滞留して集塵部９ｂに円滑に流れなくなる。
【００２２】
１次メッシュフィルタ１２としては、本発明ではとくに限定されるものではないが、たとえば直径１ｍｍ程度の開口を多数有する合成樹脂シートを採用することができる。また、合成樹脂シートの代わりにパンチングメタルなどの複数の丸孔が形成されたフィルタを採用することができる。さらには、図４に示されるように、中筒１１の上部を構成する部材そのものに直径１ｍｍ程度の開口２２を多数形成し、この部分を１次メッシュフィルタとすることもできる。
【００２３】
２次フィルタ１３は、フィルタの機能を有するものであれば本発明においてとくに限定されるものではないが、たとえばウレタンフォーム製フィルタ、好ましくは密度７０〜９０ｋｇ／ｍ３程度のイノアック・コーポレーション製の「モルトフィルタ（商品名）」などを採用することができる。
【００２４】
さらに、サイクロン集塵器９の下流側端部には、２次フィルタ１３の周辺部を押えるためにフィルタの蓋１０が取り付けられている。蓋１０の中央部には、排気口１０ａが開口されている。
【００２５】
サイクロン集塵器９は、蓋９ｄが胴部９ｅが着脱自在に気密的に連結できればよく、本発明ではとくに限定されるものではないが、たとえば蓋および胴部にそれぞれ段差部９ｆを設けて嵌合できるもの、または蓋９ｄおよび胴部９ｅにそれぞれおねじまたはめねじを形成して螺合できる連結部を有するのが好ましい。また、中筒１１を保持するために、円環状のリブ９ｇが蓋９ｄの内面に形成されている。したがって、蓋９ｄを胴部９ｅから取り外せば、中筒１１も容易に胴部９ｅ内部から取り外すことができ、その結果、集塵部９ｂに捕集されたごみを容易に外部へ捨てることができる。
【００２６】
前記実施の形態において、電動送風機７が作動すると、吸込口１５に接続したホース（図示せず）を経て床用吸込口（図示せず）から塵埃を含んだ空気がサイクロン集塵器９の吸込口１６から図２〜３の蓋９ｄの半周分の流路９ｈを通るときに旋回流となって開口９ｉを介してサイクロン部９ａに導入され、ついでサイクロン集塵器９の内周壁に沿って中筒１１の傘状の仕切板１１ａにより塵埃は空気と分離され、前述のように、それぞれ傾斜した略円錐状の１次メッシュフィルタ１２および仕切板１１ａの外周面に沿って円滑に滑りながら集塵部９ｂに集塵される。
【００２７】
しかも、サイクロン集塵器９の底面に形成された、メッシュフィルタ（図示せず）を有する開口９ｃを介して、サイクロン集塵器９は電動送風機８に連通しているため、サイクロン部９ａから集塵部９ｂへの空気の流れを発生させることができ、集塵部９ｂ内部のごみを圧縮することができる。
【００２８】
一方、前述の旋回流によって浄化された空気は、１次メッシュフィルタ１２を通過してさらに浄化され、ついで中筒１１内部を通過して２次フィルタ１３へ至る。
【００２９】
そののち、中筒１１内を通過する空気は、２次フィルタ１３でろ過されたのち、電動送風機７を通過して集中排気口（図示せず）から外部へ排気される。
【００３０】
【発明の効果】
本発明によれば、サイクロン部で空気と分離されなかったごみがフィルタ部の外周面でとどまることがなく、比重が軽いごみや髪の毛などの長いごみに対しても高い分離効果を発揮することができ、ごみはサイクロン部から集塵部へ円滑に流れることができる。そのため、ごみが中筒のフィルタ部に貼り付いたり、中筒に巻きついたりすることがなくなる。しかも、電動送風機の吸気側に設けられたフィルタの目詰まりも大幅に減少させることができる。したがって、メンテナンスが容易になるとともに製品寿命も大幅に長くなる。

[0009]
It is preferable that an inclination angle of the filter portion with respect to the axial direction of the middle cylinder is about 20 to 40 degrees.
[0010]
Further, it is preferable that at least a portion of the partition plate facing the cyclone portion has a substantially conical shape.
[0011]
It is preferable that a tilt angle of a portion of the partition plate facing the cyclone portion with respect to the axial direction of the middle cylinder is equal to or greater than a tilt angle of the filter portion with respect to the axial direction of the middle cylinder.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, the vacuum cleaner of the present invention will be described in more detail with reference to the drawings. 1 is a cross-sectional explanatory view showing an embodiment of the vacuum cleaner of the present invention, FIG. 2 is a cross-sectional explanatory view of the cyclone dust collector of FIG. 1, and FIG. 3 is a line III-III of the cyclone dust collector of FIG. FIG. 4 is a cross-sectional view of a cyclone dust collector having a round hole type filter unit showing another embodiment of the vacuum cleaner of the present invention, and FIG. 5 is a comparative example of the vacuum cleaner of the present invention. It is sectional drawing of the cyclone dust collector which has a cylindrical filter part and a flat-shaped partition plate.
[0013]
The vacuum cleaner shown in FIGS. 1 to 3 includes a vacuum cleaner upper case 1 provided with a handle 3 on an upper surface and a vacuum cleaner lower case 2 provided with a moving front wheel 4 and a rear wheel 5 on a lower surface. A battery 6, an electric blower 7 composed of a fan and a motor installed with a wall and a buffer body 8 erected from the lower case 2 and a buffer 8 interposed therebetween, and a packing 14 are detachably provided. The cyclone dust collector 9 is stored. Note that the cyclone dust collector 9 may be formed integrally with the main body of the cleaner.
[0014]
The cyclone dust collector 9 is disposed horizontally so that the rotation axis of the swirling flow generated inside the cyclone portion 9a extends substantially in the horizontal direction. That is, inside the cyclone dust collector 9, the middle cylinder 11 having the umbrella-shaped partition plate 11a is mounted in the horizontal direction. The partition plate 11a divides the internal space of the cyclone dust collector 9 into two spaces, a cyclone portion 9a for separating dust from air and a dust collection portion 9b.
[0015]
The cyclone dust collector 9 is provided with a primary mesh filter 12 corresponding to the filter section of the present invention and an additional secondary filter 13. The primary mesh filter 12 is provided at an inlet 11b formed in a portion of the middle cylinder 11 extending inside the cyclone portion 9a, and can filter air purified inside the cyclone portion 9a.
[0016]
In the present embodiment, as shown in FIG. 2, since the primary mesh filter 12 has a shape that is inclined in a substantially conical shape, light or long dust that is not separated from air inside the cyclone portion 9a. Also, it is difficult for the filter to stay on the outer peripheral surface of the primary mesh filter 12, so that the filter can smoothly flow to the dust collecting section 9 and clogging of the filter is eliminated.
[0017]
The inclination angle theta 1 of the primary mesh filter 12 with respect to the axial direction of the inner cylinder 11 is about 15 to 60 degrees, if preferably about 20 to 40 degrees, smooth the cyclone part 9a of the dust to the dust collecting portion 9b It can exhibit the effect of preventing clogging of the filter with inlet, nor affect the suction performance by the other hand the inclination angle theta 1 is too large.
[0018]
Further, in the present embodiment, at least a portion of the partition plate 11a facing the cyclone portion 9a also has a shape that is inclined in a substantially conical shape, and the inclined surface of the primary mesh filter 12 and the partition plate 11a are formed. Since the inclined surface on the cyclone portion 9a side is smoothly connected, in the vacuum cleaner according to the present embodiment, no dust is generated inside the cyclone portion 9a, and further dust is transferred from the cyclone portion 9a to the dust collecting portion 9b. It can flow smoothly.
[0019]
In particular, the inclination angle theta 2 with respect to the axial direction of the column 11 in the portion facing the cyclone part 9a side of the partition plate 11a is, the inclination angle theta 1 with substantially the same with respect to the axial direction in the cylinder 11 of the primary mesh filter 12 ( In other words, if the angle of the partition plate 11a is equal to or larger than that of the partition plate 11a (that is, the root portion of the partition plate 11a protrudes inside the cyclone portion 9a), no air pockets are generated inside the cyclone portion 9a. More preferred.
[0020]
The inclination angle theta 2 of the partition plate 11a is also inclined the angle theta 1 between 1 mesh filter 12 (15 to 60 degrees, preferably about 20 to 40 degrees) may be suitably selected from.
[0021]
Here, when the circumferential surface of the primary mesh filter 12 shown in FIG. 5 which is a comparative example of the present invention and the flat partition plate 11a are arranged orthogonally, the partition plate 11a inside the cyclone portion 9a is Since the dust accumulation A is formed around the root portion, light dust such as dust and long dust such as hair are accumulated in the dust accumulation A and do not flow smoothly to the dust collecting portion 9b.
[0022]
The primary mesh filter 12 is not particularly limited in the present invention, but may be, for example, a synthetic resin sheet having a large number of openings having a diameter of about 1 mm. Further, a filter having a plurality of round holes formed of a punching metal or the like can be employed instead of the synthetic resin sheet. Further, as shown in FIG. 4, a large number of openings 22 having a diameter of about 1 mm may be formed in the member constituting the upper portion of the middle cylinder 11, and this portion may be used as a primary mesh filter.
[0023]
The secondary filter 13 is not particularly limited in the present invention as long as it has a function of a filter. For example, a filter made of urethane foam, preferably, a filter made of INOAC CORPORATION having a density of about 70 to 90 kg / m 3 is used. Malt filter (trade name) "and the like.
[0024]
Further, a filter lid 10 is attached to a downstream end of the cyclone dust collector 9 in order to press a peripheral portion of the secondary filter 13. An exhaust port 10 a is opened at the center of the lid 10.
[0025]
The cyclone dust collector 9 is not particularly limited in the present invention as long as the lid 9d is capable of detachably and hermetically connecting the body 9e, and is not particularly limited in the present invention. It is preferable to have a connection part which can be screwed together, or a connection part which can be screwed by forming a male screw or a female screw on the lid 9d and the body part 9e, respectively. In order to hold the middle cylinder 11, an annular rib 9g is formed on the inner surface of the lid 9d. Therefore, if the lid 9d is removed from the body 9e, the middle cylinder 11 can also be easily removed from the inside of the body 9e, and as a result, the dust collected by the dust collecting part 9b can be easily thrown outside. .
[0026]
In the above-described embodiment, when the electric blower 7 is operated, air containing dust is sucked into the cyclone dust collector 9 from the floor suction port (not shown) through a hose (not shown) connected to the suction port 15. When passing from the port 16 through the flow path 9h corresponding to a half circumference of the lid 9d in FIGS. 2 and 3, a swirling flow is introduced into the cyclone portion 9a through the opening 9i, and then along the inner peripheral wall of the cyclone dust collector 9. The dust is separated from the air by the umbrella-shaped partition plate 11a of the middle cylinder 11, and as described above, the dust is collected while sliding smoothly along the slanted substantially conical primary mesh filter 12 and the outer peripheral surface of the partition plate 11a. The dust is collected by the dust part 9b.
[0027]
Moreover, since the cyclone dust collector 9 communicates with the electric blower 8 through an opening 9c having a mesh filter (not shown) formed on the bottom surface of the cyclone dust collector 9, the cyclone dust collector 9a collects the dust from the cyclone part 9a. The air flow to the dust part 9b can be generated, and the dust inside the dust collection part 9b can be compressed.
[0028]
On the other hand, the air purified by the above-described swirling flow passes through the primary mesh filter 12 and is further purified, and then passes through the inside of the middle cylinder 11 to reach the secondary filter 13.
[0029]
After that, the air passing through the middle cylinder 11 is filtered by the secondary filter 13 and then passes through the electric blower 7 and is exhausted to the outside through a centralized exhaust port (not shown).
[0030]
【The invention's effect】
According to the present invention, debris that has not been separated from air in the cyclone portion does not remain on the outer peripheral surface of the filter portion, and can exhibit a high separation effect even on long debris having a low specific gravity or hair. The refuse can flow smoothly from the cyclone section to the dust collection section. Therefore, dust does not stick to the filter portion of the middle cylinder or wrap around the middle cylinder. In addition, clogging of the filter provided on the intake side of the electric blower can be significantly reduced. Therefore, maintenance becomes easy and the product life is greatly extended.
