上流フィルター12は、カバー9と一体成形または、凹凸の嵌合によってカバー9に取り付けられており、カバー9は、ビジョウウエ14とビジョウヨコ15が、下流フィルター10に設けられた係止部16と集塵ケース8に設けられた係部横18にそれぞれ嵌合することで固定されるようになっている。   The upstream filter 12 is integrally formed with the cover 9 or attached to the cover 9 by fitting unevenness. The cover 9 includes a bijou 14 and a bijou 15, and an engaging portion 16 provided on the downstream filter 10 and dust collecting. It is fixed by being fitted to the engaging portion side 18 provided in the case 8.

またカバー9と集塵ケース8は、パッキンB20と、図4に示すパッキンC30とでエアータイトされる構成となっている。フタ11には、パッキンA19が設けられており、フタ11に設けられた軸13を中心に回動可能となっている。フタ11は、ストッパー17とによって集塵ケース8に固定でき、パッキンA19にて、集塵ケース8とエアータイトできる構成となっている。21は、集塵ケース8を掃除機本体1から取り出すときや集塵ケース8を持ち運ぶ際に握るハンドルである。   Further, the cover 9 and the dust collecting case 8 are configured to be airtight with a packing B20 and a packing C30 shown in FIG. The lid 11 is provided with a packing A19 and is rotatable about a shaft 13 provided on the lid 11. The lid 11 can be fixed to the dust collection case 8 by a stopper 17 and can be airtight with the dust collection case 8 by packing A19. Reference numeral 21 denotes a handle that is gripped when the dust collection case 8 is taken out from the cleaner body 1 or when the dust collection case 8 is carried.

図3に示すように、上流フィルター12は、排気筒22と、外周側面に複数の貫通孔25を有する延出部23からなり、排気筒22と延出部23は、仕切り面31によって区切られている。また仕切り面31を境界として、上方が分離室42、下方が集塵室41となっている。また、延出部23の外周側面は、集塵室41の底面に対して、垂直方向に延出されている。また、延出部23の外周側面は、集塵室41の底面に対して、垂直方向に延出され、延出部23と、集塵室41の内壁及び底面とのそれぞれの間に所定の間隙を設けている。   As shown in FIG. 3, the upstream filter 12 includes an exhaust tube 22 and an extending portion 23 having a plurality of through holes 25 on the outer peripheral side surface. The exhaust tube 22 and the extending portion 23 are separated by a partition surface 31. ing. Further, with the partition surface 31 as a boundary, the upper portion is a separation chamber 42 and the lower portion is a dust collection chamber 41. Further, the outer peripheral side surface of the extending portion 23 extends in the vertical direction with respect to the bottom surface of the dust collection chamber 41. Further, the outer peripheral side surface of the extending portion 23 extends in a direction perpendicular to the bottom surface of the dust collecting chamber 41, and a predetermined interval is provided between the extending portion 23 and the inner wall and bottom surface of the dust collecting chamber 41. A gap is provided.

下流フィルター10は、ビジョウウエ14と係止部16との嵌合、およびフィルター軸28と集塵ケース8に設けた軸受け部32との固定によって集塵ケース8と固定される。図4に示すように、下流フィルター10の後方に設けられた電動送風機6によって、吸気口26から流入した塵埃を含む空気は、壁面39によって、排気筒22側に誘導され、誘導された塵埃を含む空気は、排気筒22の接線方向から分離室42内へ導入される。導入された塵埃を含む空気は、排気筒22によって分離室42内で、塵埃は遠心分離され集塵室41に蓄積する。   The downstream filter 10 is fixed to the dust collecting case 8 by fitting between the vision way 14 and the locking portion 16 and fixing the filter shaft 28 and the bearing portion 32 provided in the dust collecting case 8. As shown in FIG. 4, the air containing dust flowing in from the air inlet 26 by the electric blower 6 provided behind the downstream filter 10 is guided to the exhaust tube 22 side by the wall surface 39, and the induced dust is removed. The contained air is introduced into the separation chamber 42 from the tangential direction of the exhaust tube 22. The introduced air containing the dust is separated in the separation chamber 42 by the exhaust tube 22, and the dust is centrifuged and accumulated in the dust collection chamber 41.

集塵室41に蓄積した塵埃は、フタ11に設けられたストッパー17をはずしてやることで、フタ11がヒンジ部13を回転軸として約90度回動し、集塵室41内の塵埃を捨てることができる。一方空気は、上流フィルター12を通過し吸気通路B38、吸気通路A37を通過し下流フィルター10に配設されたプリーツフィルター29を通過する。分離室42にて遠心分離されず吸気通路B38及び吸気通路A37を抜けた塵埃は、プリーツフィルター29にて捕集される。   The dust accumulated in the dust collection chamber 41 is removed by removing the stopper 17 provided on the lid 11, so that the lid 11 rotates about 90 degrees around the hinge portion 13 as a rotation axis, and the dust in the dust collection chamber 41 is discarded. be able to. On the other hand, the air passes through the upstream filter 12, passes through the intake passage B 38 and the intake passage A 37, and passes through the pleated filter 29 disposed in the downstream filter 10. Dust that has not been centrifuged in the separation chamber 42 and has passed through the intake passage B 38 and the intake passage A 37 is collected by the pleated filter 29.

プリーツフィルター29で捕集された塵埃は、下流フィルター10に配設されたジョジンレバー33を、ジョジンレバー33を固定するレール状のホルダー34上を動かすことによって生じる振動により、プリーツフィルター29から剥がれ落ち、細塵室35に蓄積する構成となっている。またホルダー34は、下流フィルター10にビスで固定されている。   The dust collected by the pleated filter 29 is peeled off from the pleated filter 29 due to the vibration generated by moving the jog lever 33 disposed in the downstream filter 10 on the rail-shaped holder 34 that fixes the jog lever 33. The dust is stored in the dust chamber 35. The holder 34 is fixed to the downstream filter 10 with screws.

図5に示すように、集塵室41に蓄積された塵埃36は、空気の流れにより分離室42側へ舞い上がろうとする。この舞い上がろうとする空気は、延出部23の側面に設けた貫通孔25を通して延出部23の内側から外側へ向かって流れるため、空気の流れによって舞い上がった塵埃36は、延出部23内に留まるため、排気筒22に巻きつくなどして目詰まりを起こし吸引力が低下するなどの不具合を防ぐことができる。   As shown in FIG. 5, the dust 36 accumulated in the dust collecting chamber 41 tends to fly to the separation chamber 42 side by the air flow. The air that is about to flow up flows from the inside to the outside of the extending portion 23 through the through-hole 25 provided on the side surface of the extending portion 23, so that the dust 36 that has risen by the air flow enters the extending portion 23. Therefore, it is possible to prevent problems such as clogging around the exhaust tube 22 and a reduction in suction force.

また延出部23の底面に配設されたフランジ24によって舞い上がろうとする塵埃をよ
り延出部23内部に留ませることができ、舞い戻りによる性能低下を防ぐことができる。
Further, the dust 24 that is about to fly up can be retained in the extension portion 23 by the flange 24 disposed on the bottom surface of the extension portion 23, and performance degradation due to return can be prevented.

尚、図6に示すように、延出部23の径を排気筒22の径よりも大きくすれば、より多くの塵埃を延出部23内に留まらせることができ、舞い戻りによる性能低下を更に確実に防ぐことができる。   In addition, as shown in FIG. 6, if the diameter of the extension part 23 is made larger than the diameter of the exhaust pipe 22, more dust can be kept in the extension part 23, and the performance deterioration due to the return is further reduced. It can be surely prevented.

また図7に示すように、延出部23に、排気筒22に設けた雌ねじ(図示せず)にねじ嵌合するねじ部27を設けて、排気筒22に、延出部23を着脱自在に固定できるようにすれば、延出部23のみを取り外して洗浄することができ、常に清潔に保つことができる。   Further, as shown in FIG. 7, the extension portion 23 is provided with a screw portion 27 that is screw-fitted to a female screw (not shown) provided on the exhaust tube 22, and the extension portion 23 is detachably attached to the exhaust tube 22. If it can fix to, it can remove and wash | clean only the extension part 23, and can always keep clean.

また、上記実施の形態における集塵装置7を掃除機本体1に搭載することにより、使い勝手のよい電気掃除機を提供することができることは言うまでも無い。   Moreover, it goes without saying that an easy-to-use vacuum cleaner can be provided by mounting the dust collector 7 in the above embodiment on the cleaner body 1.

以上のように、本発明に係る集塵装置は、延出部に設けた貫通孔を介して内側から外側へ向かう風の流れによって、集積室に堆積した綿ごみ等の塵埃を延出部内に留め、舞い上がりを防止することができるもので、各種電気掃除機に適用できる。   As described above, the dust collector according to the present invention causes dust such as cotton dust accumulated in the accumulation chamber to enter the extension portion by the flow of air from the inside to the outside through the through hole provided in the extension portion. It can be fastened and prevented from rising, and can be applied to various vacuum cleaners.
