The downstream filter 10 of the invention dust collector 7 is set to be released before the timing at which the lock (the locking portion 11 and the locked portion 10a) is released.

以上のように構成された本実施の形態における電気掃除機の動作、作用について以下に説明する。 The operation and action of the vacuum cleaner in the present embodiment configured as described above will be described below.

図２（ｂ）に示すように本発明の集塵装置７はごみ捨て時に下側が開放する構造となっているが、そのごみ捨て時の動作を具体的に説明する。電気掃除機本体１に収納された集塵装置７はごみ捨て時に本体収納部（図示せず）から集塵ケースの持ち手部８ｄを持って取り出される。取り出された集塵装置７は持ち手部８ｄ近傍の操作部１２ｂを押す事で、操作部品１２の両サイドのアーム部１２ａを介して、両側の係止部１１を下方に摺動させる。そして係止部１１が下方に摺動し、下流フィルター１０の下方に配した被係止部１０ａとの嵌合が解除され、下流フィルター１０が集塵ケース８上方に設けられた回動軸を中心に約１１０°開く。それに付随して上流フィルター９も開き、集塵ケース８の集塵部８ｂに蓄積されたゴミを捨てられるよう開放される。これにより、ごみ捨ての操作が片手で簡単に下向き開放にて行うことができ、蓋部閉状態での保持も上部の回動軸部と側面下方２箇所でロックされ、蓋部の閉状態における保持も確実に行う事ができる。また、開放方向を下向きにする事で、下流フィルター１０の下部にたまるジョジンレバー１３によりプリーツフィルターから除塵された細塵の処理がしやすくなる上に、お手入れ時のほこりの舞い上がりを抑えることができる。次に、ごみ捨て時の上流フィルター９及び下流フィルター１０を開方向に付勢する付勢手段及び上流フィルター９の固定部の動作詳細についても説明する。取り出された集塵装置７の操作部品トータルのストロークは５ｍｍであり、約１ｍｍ押すことで、まず前記の上流フィルター９のみの固定部である上流フィルター固定用係止部１２ｄ及び上流フィルター固定用被係止部９ｇが解除される。さらに１〜１．５ｍｍ押さえることで、下流フィルター１０のロックである係止部１１と被係止部１０ａのロックが解除される。解除と同時に下流フィルター１０を開方向に付勢する付勢手段であるバネ１５により、下流フィルター１０が開方向に押し出される。また、このバネ１５は上流フィルター９と下流フィルター１０の間にあり、ごみ捨てを行う時、両フィルターが回動する間も、両フィルター間に常にすき間を設ける役割を果たし、下流フィルター１０に付着した細塵及びプリーツフィルターから除塵された細塵が落ちやすくなる。さらに操作部品１２を下方に押し下げると、図６に示すとおり、操作部１２ｂの下部に傾斜面を設けた２箇所の当接部１２ｃが上流フィルター９に形成した被当接部９ｈを押さえ、上流フィルター９を開方向に押し出す動作となっている。また、当接部１２ｃは回動軸近傍に位置し、被当接部９ｈはヒンジ部９ｆに一体的に形成している為、ゴミ捨て時、当接部１２ｃが上流フィルター９に当接した後の動作量が少なくても上流フィルター９の回動角度が大きくなり、また、ヒンジ部９ｆは従来より強度が確保されているので、耐久性を確保できると共に、たわみ等の応力分散を抑制し当接部１２ｃの動作を効率的に上流フィルター９又は下流フィルター１０に伝達することができるので、少ないストロークで確実に上流フィルター９又は下流フィルター１０を大きく開かせることができて、ゴミの廃棄を容易に行え、使用性を向上させることができる。さらに、当接部１２ｃと被当接部９ｈを複数箇所設けている為、当接部１２ｃ及び被当接部９ｈに加わる応力を分散できるので、強度や耐久性を向上させることができる。操作部１２ｂの操作により上流フィルター９および下流フィルター１０の閉状態が解除された後、当接部１２ｃと被当接部９ｈが当接する構成としているので、スムーズに上流フィルター９及び下流フィルター１０が開き、ゴミ捨て性を向上させることができる。また、組立時には操作部１２ｂと当接部１２ｃを一体形成した操作部品１２を組み込むだけの為、ゴミ捨てのし易さは確保したままで、部品点数を削減でき、安価かつ組立性を向上させることができる。また、ゴミ捨て時は図８（ａ）のような形態となり、上流フィルター９に配する粗い塵埃を捕集するネットフィルター９ｂのお手入れはこの状態で行う。また、下流フィルター１０の細かい塵埃を捕集するプリーツフィルター部のお手入れをする際に、上流フィルター９が下流フィルター１０の上に配したままでは、お手入れがしにくい（できない）ため、図８（ｂ）のとおり、上流フィルター９のみを集塵ケース８側に回動させ、前記上流フィルター固定用係止部１２ｄ及び上流フィルター固定用被係止部９ｇにて上流フィルター９を集塵ケース８側に固定させる。上流フィルター９は集塵ケース８側に爪勘合にて保持されることで、下流フィルター１０のお手入れがしやすくなる。 As shown in FIG. 2 (b), the dust collector 7 of the present invention has a structure in which the lower side is opened when the waste is discarded. The operation when the dust is discarded will be specifically described. The dust collector 7 stored in the electric vacuum cleaner main body 1 is taken out from the main body storage portion (not shown) with the handle portion 8d of the dust collecting case when throwing away the garbage. The taken-out dust collector 7 pushes the operating portion 12b near the handle portion 8d, thereby sliding the locking portions 11 on both sides downward via the arm portions 12a on both sides of the operating component 12. And the latching | locking part 11 slides below, the fitting with the to-be-latched part 10a distribute | arranged below the downstream filter 10 is cancelled | released, and the downstream shaft 10 has the rotating shaft provided in dust collection case 8 upper direction. Open about 110 ° in the center. Along with this, the upstream filter 9 is also opened and opened so that the dust accumulated in the dust collecting part 8b of the dust collecting case 8 can be discarded. As a result, the waste disposal operation can be easily performed with one hand by opening downward, and the lid is closed when the lid is closed, and the upper pivot shaft and the side are locked at two locations below, and the lid is held in the closed state. Can also be done reliably. Further, by setting the opening direction downward, it becomes easier to handle fine dust removed from the pleated filter by the jog lever 13 that accumulates in the lower part of the downstream filter 10, and it is possible to suppress the rising of dust during cleaning. . Next, details of the operation of the urging means for urging the upstream filter 9 and the downstream filter 10 in the opening direction and the fixing part of the upstream filter 9 at the time of waste disposal will be described. The total stroke of the operation parts of the dust collector 7 taken out is 5 mm. When the stroke is pushed by about 1 mm, the upstream filter fixing locking portion 12d, which is the fixing portion of the upstream filter 9 only, and the upstream filter fixing cover The locking portion 9g is released. By further pressing 1 to 1.5 mm, the locking of the locking portion 11 and the locked portion 10a, which are the lock of the downstream filter 10, is released. Simultaneously with the release, the downstream filter 10 is pushed in the opening direction by a spring 15 which is a biasing means for biasing the downstream filter 10 in the opening direction. The spring 15 is located between the upstream filter 9 and the downstream filter 10, and when the waste is discarded, it plays a role of always providing a gap between the two filters even when both filters rotate, and is attached to the downstream filter 10. Fine dust removed from fine dust and pleated filter is easy to fall. When the operation component 12 is further pushed downward, as shown in FIG. 6, the two contact portions 12c having the inclined surface at the lower portion of the operation portion 12b press the contacted portion 9h formed on the upstream filter 9, and the upstream The filter 9 is pushed out in the opening direction. Further, the abutting portion 12c is located in the vicinity of the rotation shaft, and the abutted portion 9h is integrally formed with the hinge portion 9f, so that the abutting portion 12c abuts on the upstream filter 9 when the dust is discarded. Even if the amount of later movement is small, the rotation angle of the upstream filter 9 becomes large, and the hinge portion 9f is stronger than before so that durability can be ensured and stress distribution such as deflection can be suppressed. Since the operation of the contact portion 12c can be efficiently transmitted to the upstream filter 9 or the downstream filter 10, the upstream filter 9 or the downstream filter 10 can be reliably opened with a small stroke, and waste can be discarded. It can be performed easily and usability can be improved. Furthermore, since the contact part 12c and the contacted part 9h are provided at a plurality of locations, the stress applied to the contact part 12c and the contacted part 9h can be dispersed, so that the strength and durability can be improved. After the closed state of the upstream filter 9 and the downstream filter 10 is released by the operation of the operation part 12b, the contact part 12c and the contacted part 9h are in contact with each other, so that the upstream filter 9 and the downstream filter 10 are smoothly connected. It can be opened and garbage disposal can be improved. Further, since only the operation part 12 in which the operation part 12b and the contact part 12c are integrally formed is assembled at the time of assembling, the number of parts can be reduced while the ease of throwing away the dust is secured, and the assembling efficiency is improved. be able to. Further, when the trash is thrown away, the configuration is as shown in FIG. 8A, and the net filter 9b that collects coarse dust disposed on the upstream filter 9 is maintained in this state. In addition, when cleaning the pleated filter portion that collects fine dust in the downstream filter 10, if the upstream filter 9 is left on the downstream filter 10, the cleaning is difficult (cannot be performed). As shown in (b), only the upstream filter 9 is rotated to the dust collecting case 8 side, and the upstream filter 9 is moved to the dust collecting case 8 by the upstream filter fixing locking portion 12d and the upstream filter fixing locked portion 9g. Fix to the side. Since the upstream filter 9 is held on the dust collecting case 8 side by nail fitting, the downstream filter 10 can be easily maintained.

以上のように、本発明にかかる集塵装置は、ゴミ捨てのし易さは確保したままで、部品点数を削減でき、安価かつ組立性を向上させることができるので、着脱自在の集塵装置を有する家庭用、業務用電気掃除機に特に有用である。 As described above, the dust collector according to the present invention can reduce the number of parts while maintaining the ease of throwing away the dust, and can improve the low cost and assemblability. It is particularly useful for household and commercial vacuum cleaners having
