次に、電動送風機１４は、クッション前４２及びクッション後１７を介して下カバー１１と上カバー１６とで狭持されている。１９は、電動送風機室１５と集塵室１３を仕切る仕切壁であり、下カバー１１及び集塵蓋１８に相対するように設けられており、この仕切壁１９同士の間にパッキン４２を介して空気のタイトを行い、気密性を確保するようにしている。仕切壁１９に設けた連通口２０は、集塵室１３と電動送風機１４とを連通するもので、格子状のリブが形成されている。前記連通口２０の集塵室１３側前方所謂集塵室１３内には、下カバー１１より立設し収納された集塵手段１２の集塵部１２ｂの外面に臨んで、振動動作を与えるための振動板２９を有した除塵手段２８が設けられている。 Next, the electric blower 14 is held between the lower cover 11 and the upper cover 16 via the cushion front 42 and the cushion rear 17. Reference numeral 19 denotes a partition wall that partitions the electric blower chamber 15 and the dust collection chamber 13, and is provided so as to face the lower cover 11 and the dust collection lid 18, and a packing 42 is interposed between the partition walls 19. Air tightness is performed to ensure airtightness. The communication port 20 provided in the partition wall 19 communicates the dust collection chamber 13 and the electric blower 14, and is formed with grid-like ribs. In the so-called dust collecting chamber 13 in front of the communication port 20 on the dust collecting chamber 13 side, facing the outer surface of the dust collecting portion 12b of the dust collecting means 12 which is erected and stored from the lower cover 11 to give a vibration operation. A dust removing means 28 having a vibration plate 29 is provided.

振動板２９は、集塵部１２ｂの上面と電動送風機１４と対向する背面に沿わせ、さらに集塵部１２ｂの上面側に位置する面を集塵手段１２がほぼ開ききった形状に沿わせた構成としている。また、振動板２９は集塵部１２ｂの上面側に位置する面に通気穴２９ａが設けられている。 The vibration plate 29 is arranged along the upper surface of the dust collecting unit 12b and the rear surface facing the electric blower 14, and the surface located on the upper surface side of the dust collecting unit 12b is arranged along the shape in which the dust collecting means 12 is almost fully opened. It is configured. Further, the diaphragm 29 is provided with a vent hole 29a on a surface located on the upper surface side of the dust collecting portion 12b.

Moreover, the capacity | capacitance of the dust collection part 12b can be used to the maximum, and also the air permeability of the dust collection part 12b can be improved. As a result, it is possible to reduce the reduction in suction air and improve the suction efficiency.

次に、除塵手段２８の構成及び動作の詳細について説明する。 Next, the details of the configuration and operation of the dust removing means 28 will be described.

図４、５において、除塵手段２８は、集塵室１３下方の下カバー１１下部内に格納され蓋カバー３０で固定されており、除塵手段２８の本体ケース３１からは、可動板３２より立設した中空円柱状のアーム３３が集塵室１３内へ突出しており、このアーム３３に格子形状をなす振動板２９の下部にある突起４８が挿入嵌合される。 4 and 5, the dust removing means 28 is housed in the lower part of the lower cover 11 below the dust collecting chamber 13 and is fixed by a cover cover 30. The dust removing means 28 is erected from the movable plate 32 from the main body case 31 of the dust removing means 28. The hollow cylindrical arm 33 protrudes into the dust collecting chamber 13, and a projection 48 on the lower portion of the diaphragm 29 having a lattice shape is inserted and fitted into the arm 33.

振動板２９は、仕切壁１９の連通口２０に面する集塵部１２ｂの外面に臨んだ位置に配設されているため、集塵部１２ｂを通過して連通口２０から吸引される吸引風を遮らないように格子形状としている。また、アーム３３はリング状のゴム製ブッシング３４を介して本体ケース３１に固定されている。 Since the diaphragm 29 is disposed at a position facing the outer surface of the dust collecting portion 12b facing the communication port 20 of the partition wall 19, suction air sucked from the communication port 20 through the dust collecting portion 12b. It has a lattice shape so as not to block. The arm 33 is fixed to the main body case 31 via a ring-shaped rubber bushing 34.

本体ケース３１内には、電磁石３５と電磁石３６の吸引作用面と対向して平行に配置された磁石３７を先端部に固着した可動板３２が内蔵されており、可動板３２の磁石３７と反対側の一端はゴム製のスリーブ３８を介してネジ３９により、可動板３２が回動自在となるように本体ケース３１に固定されている。 In the main body case 31, a movable plate 32 is built in which a magnet 37 disposed in parallel to face the attracting action surfaces of the electromagnet 35 and the electromagnet 36 is fixed to the tip, and is opposite to the magnet 37 of the movable plate 32. One end on the side is fixed to the main body case 31 by a screw 39 through a rubber sleeve 38 so that the movable plate 32 is rotatable.

振動制御回路（図示せず）によりスイッチ（図示せず）がＯＮされ電磁石３５、３６にＡＣ１００Ｖ電源が通電されると、電磁石３５、３６に生じた磁界により先端部に磁石３７を固着した可動板３２はネジ３９で固定した一端を支点として、アーム３３がゴム製ブッシング３４を前後に撓ませながら矢印４０、４１方向へＡＣ１００Ｖ電源の電源周波数（５０Ｈｚまたは６０Ｈｚ）に応じた周期で振動する。その振動はアーム３３を介して振動板２９に伝えられ、振動板２９も同様に矢印４０、４１方向へ振動し、集塵手段１２の集塵部１２ｂの外面を振動させ除塵を行うものである。 When a switch (not shown) is turned on by a vibration control circuit (not shown) and an AC 100 V power supply is energized to the electromagnets 35 and 36, a movable plate having a magnet 37 fixed to the tip portion by a magnetic field generated in the electromagnets 35 and 36. 32, with one end fixed by a screw 39 as a fulcrum, the arm 33 vibrates in a direction corresponding to the power frequency (50 Hz or 60 Hz) of the AC 100V power source in the directions of arrows 40 and 41 while bending the rubber bushing 34 back and forth. The vibration is transmitted to the vibration plate 29 via the arm 33, and the vibration plate 29 similarly vibrates in the directions of arrows 40 and 41 to perform dust removal by vibrating the outer surface of the dust collecting portion 12b of the dust collecting means 12. .

以上のように本実施の形態によれば、集塵部１２ｂに付着した塵埃を除塵する除塵手段２８を備えたことにより、集塵手段１２の集塵部１２ｂに付着し堆積した塵埃をはたき落とすことが可能となる。その結果、吸引風の低下を減少させ吸引効率を向上させることができる。 As described above, according to the present embodiment, the dust removing means 28 for removing dust adhering to the dust collecting portion 12b is provided, so that the dust adhering to and accumulated on the dust collecting portion 12b of the dust collecting means 12 is removed. It becomes possible. As a result, it is possible to reduce the reduction in suction air and improve the suction efficiency.

また、除塵手段２８を集塵室１３内部に設けたことにより、除塵手段２８の構成として複数の部品による動作の連動が不用となり、且つ集塵手段１２に直接除塵動作を与えることが可能となるため、構成が簡素化され、部品数の削減並びに関係部品の低減による規制緩和で除塵手段２８の構成の多様化が容易に実現できる。 Further, by providing the dust removing means 28 inside the dust collecting chamber 13, it becomes unnecessary to interlock the operation of a plurality of parts as the configuration of the dust removing means 28, and it is possible to directly apply the dust removing operation to the dust collecting means 12. Therefore, the configuration is simplified, and diversification of the configuration of the dust removing means 28 can be easily realized by reducing the number of components and relaxing the regulation by reducing the number of related components.

また、集塵室１３内部に設けた集塵手段１２の集塵部１２ｂに除塵手段２８が動作を加えるようにしたので、主として塵埃が付着し堆積した部分を直接動作させることになるので効率的な除塵効果が得られるものとなる。 Further, since the dust removing means 28 is operated on the dust collecting portion 12b of the dust collecting means 12 provided in the dust collecting chamber 13, the portion where dust is mainly deposited and accumulated is directly operated, which is efficient. A good dust removal effect.

また、集塵室１３の内部に設けた集塵手段１２の集塵部１２ｂを軟質材で形成したことにより、除塵手段２８による動作が軟質材で形成された集塵部１２ｂのみの動きで緩和され、硬質材で形成した固定部１２ａまでは、前記除塵動作が伝わらない。その結果、逆止弁２２と集塵手段１２の固定部１２ａとの密着部への動きの連動が無く、タイト性が向上し、ゴミ漏れ等が解消されるものとなる。 Further, since the dust collecting portion 12b of the dust collecting means 12 provided in the dust collecting chamber 13 is formed of a soft material, the operation by the dust removing means 28 is mitigated by the movement of only the dust collecting portion 12b formed of the soft material. The dust removal operation is not transmitted to the fixed portion 12a formed of a hard material. As a result, there is no interlocking of movement of the check valve 22 and the fixed portion 12a of the dust collecting means 12 to the close contact portion, the tightness is improved, and dust leakage or the like is eliminated.

また、除塵手段２８を、電動送風機室１５と集塵室１３とを連通する連通口２０の近傍に配設したので、吸引風が通過し塵埃の付着が多い集塵部１２ｂの除塵が可能となる。その結果、前記除塵手段２８における除塵効果の拡大が図れるものとなる。 Further, since the dust removing means 28 is disposed in the vicinity of the communication port 20 that communicates the electric blower chamber 15 and the dust collecting chamber 13, the dust collecting portion 12b that has a lot of dust adhering through the suction air can be removed. Become. As a result, the dust removal effect in the dust removal means 28 can be expanded.

又、除塵手段２８を連通口２０に対向した位置に配設することにより、吸引風が通過し塵埃の付着が最も多い集塵部１２ｂの除塵が可能となる。その結果、より除塵手段２８における除塵効果の拡大が図れるものとなる。また、振動板２９を格子状に形成したことにより、通気性を確保し、吸引風に対する通風抵抗が低減でき、電気掃除機における吸い込み性能の劣化を防止することができる。 Further, by disposing the dust removing means 28 at a position facing the communication port 20, the dust collecting portion 12b where the suction air passes and the most dust is attached can be removed. As a result, the dust removal effect in the dust removal means 28 can be further expanded. Moreover, by forming the diaphragm 29 in a lattice shape, air permeability can be ensured, ventilation resistance against suction air can be reduced, and deterioration of suction performance in the vacuum cleaner can be prevented.

また、図１に示すように、集塵蓋１８と、集塵手段１２の集塵部１２ｂの上に位置する部分との間に空間１３ａを確保するようにすれば、集塵手段１２の集塵部１２ｂの上面での通気性を大幅に向上させることができる。 In addition, as shown in FIG. 1, if a space 13 a is secured between the dust collection lid 18 and a portion of the dust collection means 12 positioned on the dust collection part 12 b, the dust collection means 12 is collected. The air permeability on the upper surface of the dust part 12b can be greatly improved.

さらに、振動板２９と集塵手段１２の集塵部１２ｂの上面と接する面積を、振動板２９と集塵部１２ｂの背面と接触する面積よりも大きくするようにすれば、集塵部１２ｂの上面に付着し堆積した塵埃をより多くはたき落とすことができ、それにより吸引効率をより良化させることができる。 Furthermore, if the area where the vibration plate 29 and the upper surface of the dust collecting portion 12b of the dust collecting means 12 are in contact with each other is made larger than the area where the vibration plate 29 and the rear surface of the dust collecting portion 12b are contacted, the dust collecting portion 12b A larger amount of dust deposited on the upper surface can be scraped off, whereby the suction efficiency can be further improved.

また、バスケット２３を、吸引風でほぼ開ききった集塵手段１２の外形形状に沿うように形成し、バスケット２３で前記集塵手段１２を押さえるようにすれば、集塵手段１２の上面及び背面での通過風が増加し、その部分での塵埃の付着、堆積が多くなるので、その部分に集塵手段１２による除塵動作を加える事で、より除塵手段２８による除塵効果の拡大が図れるものとなる。 Further, if the basket 23 is formed so as to conform to the outer shape of the dust collecting means 12 that is almost fully opened by the suction air, and the dust collecting means 12 is pressed by the basket 23, the upper surface and the rear surface of the dust collecting means 12 are obtained. As the passing air increases at this part and dust adheres and accumulates at that portion, the dust removal effect by the dust removal means 28 can be further expanded by adding a dust removal operation by the dust collecting means 12 to that part. Become.

以上のように、本発明にかかる電気掃除機は、集塵手段に付着し堆積した塵埃を効率よくはたき落とすことで、吸引風の低下を減少させ吸引効率を良化させることができるもので、家庭用、業務用電気掃除機、集塵機に広く適用できる。 As described above, the electric vacuum cleaner according to the present invention can efficiently reduce the suction air flow and improve the suction efficiency by efficiently dusting off the dust deposited on the dust collecting means. Widely applicable to household and commercial vacuum cleaners and dust collectors.
