Description

本発明は電気掃除機、詳しくはフィルターとフィルターカバーを備えた電気掃除機に関するものである。   The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner having a filter and a filter cover.

従来、フィルターとフィルターカバーを備えた電気掃除機として、フィルターを保持するフィルターカバーに爪状の係止手段を一体的に備えたものがある。フィルターカバーは樹脂成形部品であり、そのフィルターカバーの係止手段を本体に係止させて取付けている（例えば、特許文献１参照）。   2. Description of the Related Art Conventional vacuum cleaners that include a filter and a filter cover include a filter cover that holds a filter and a claw-like locking unit that is integrated with the filter cover. The filter cover is a resin molded part, and the filter cover locking means is locked and attached to the main body (for example, see Patent Document 1).

日本特開２００２−２７２６５６号公報（第３頁、図４）Japanese Unexamined Patent Publication No. 2002-272656 (page 3, FIG. 4)

前述した従来の電気掃除機においては、２箇所の係止手段を本体に係止させてフィルターカバーを本体に取付けているが、この際、樹脂で形成されているフィルターカバーを弾性変形させている。このように樹脂成形部品を弾性変形させて取付ける方法はよく用いられている。しかし、樹脂形成部品を繰り返し弾性変形させると、変形部分に疲労が残り弾性力が低下することから係止力が弱まり、電気掃除機の使用中に、意図しないフィルターカバーの外れが発生しフィルターの保持ができなくなるなど安全性、耐久性に課題があった。   In the above-described conventional vacuum cleaner, the filter cover is attached to the main body by locking the two locking means to the main body. At this time, the filter cover formed of resin is elastically deformed. . Such a method of attaching the resin molded part by elastic deformation is often used. However, if the resin-formed parts are repeatedly elastically deformed, fatigue remains in the deformed part and the elastic force decreases, so the locking force weakens, and an unintentional removal of the filter cover occurs during use of the vacuum cleaner. There were problems with safety and durability, such as the inability to hold.

本発明は、前述のような課題を解決するためになされたものであり、フィルターカバーの本体との係止手段の耐久性を向上しながら、係止及び解除作業が容易な電気掃除機を提供することを目的とする。   The present invention has been made to solve the above-described problems, and provides an electric vacuum cleaner that can be easily locked and released while improving the durability of the locking means with the filter cover body. The purpose is to do.

本発明に係る電気掃除機は、本体内に配設された電動送風機と、電動送風機により吸引された空気に含まれる塵埃を捕集する集塵器と、集塵器の下流側に設けられたフィルターと、フィルターを開閉自在に覆うフィルターカバーとを備え、フィルターカバーは、一端側が本体に回動自在に軸支され、他端側が本体に設けられた係止部と係脱可能に係止され、当該係止部から係止状態の解除操作をする係止解除ボタンを備えたものである。   An electric vacuum cleaner according to the present invention is provided on the downstream side of an electric blower disposed in a main body, a dust collector that collects dust contained in air sucked by the electric blower, and a dust collector. The filter cover includes a filter and a filter cover that covers the filter so that the filter can be opened and closed. One end of the filter cover is pivotally supported by the main body, and the other end is removably locked to a locking portion provided on the main body. The lock release button for releasing the lock state from the lock portion is provided.

本発明によれば、フィルターカバーは本体との係止状態の解除操作をする係止解除ボタンを備えたので、フィルターカバーを弾性変形させることなく本体に係止させることができることから、係止と解除を繰り返すことに対して耐久性が向上し、係止解除ボタンを操作すると係止手段が解除されるようにしたので、意図的にフィルターカバーを弾性変形させないので、フィルターカバーの係止解除が安全で容易となり作業性が向上する。   According to the present invention, the filter cover is provided with the lock release button for releasing the lock state with the main body, so that the filter cover can be locked to the main body without elastic deformation. Durability is improved against repeated release, and the lock means is released when the lock release button is operated, so the filter cover is not intentionally elastically deformed. It becomes safe and easy, and workability is improved.

ホース体６は図１に示すように塵埃を吸引するための吸込具６ｆと、伸縮構造を有する硬質延長管部６ｅと、電気掃除機１００を操作するための入力を行う操作部６ｄを備え電気掃除機１００の取り回しおよび吸込具６ｆを操る把持部６ｃと、例えば蛇腹のような可撓性を有する軟質管部６ｂと、挿入部６ａとにより構成されている。   As shown in FIG. 1, the hose body 6 includes a suction tool 6 f for sucking dust, a hard extension pipe portion 6 e having a telescopic structure, and an operation portion 6 d for performing input for operating the vacuum cleaner 100. It is comprised of a gripping portion 6c for handling the vacuum cleaner 100 and operating the suction tool 6f, a flexible tube portion 6b having flexibility such as a bellows, and an insertion portion 6a.

本体１において、ホース体接続部４にはホース体接続口７が設けられており、図１に示すようにホース体６の一端部に設けられた挿入部６ａを着脱自在に接続できるようになっている。   In the main body 1, a hose body connection port 7 is provided in the hose body connection portion 4, and an insertion portion 6 a provided at one end portion of the hose body 6 can be detachably connected as shown in FIG. 1. ing.

図２、図３に示すように本体１の上部を構成する上ケース２は、前側から後側に向かって上方に傾斜しており、その傾斜に沿って図５に示すように本体１の側面の一方に吸気管５、他方に排気管１８を有している。   2 and 3, the upper case 2 constituting the upper part of the main body 1 is inclined upward from the front side toward the rear side, and along the inclination, the side surface of the main body 1 is shown in FIG. One has an intake pipe 5 and the other has an exhaust pipe 18.

吸気管５は一端をホース体接続部４と流入口１３で接続され、ホース体接続部４と吸気管５の空気経路とが連通するようになっている。また、上ケース２には、集塵器８に設けられた空気排出部１６と空気経路とを連通するための連通口１７（図７（ａ）、図８参照）を備えるフィルターカバー１１が取付けられている。なお、フィルターカバー１１の取付け構造等については後段で詳述する。   One end of the intake pipe 5 is connected to the hose body connecting portion 4 by the inflow port 13 so that the hose body connecting portion 4 and the air path of the intake pipe 5 communicate with each other. Further, the upper case 2 is provided with a filter cover 11 having a communication port 17 (see FIGS. 7A and 8) for communicating the air discharge portion 16 provided in the dust collector 8 and the air path. It has been. The mounting structure of the filter cover 11 will be described in detail later.

本体１内には図４に示すように、電動送風機２１が、電動送風機収納室２０に収納され、配設されている。電動送風機２１は、塵埃を吸引するための吸引風を発生させる。電動送風機２１の空気経路上流にはフィルターカバー１１に覆われ保持されているフィルターユニット２３が配設されている。フィルターユニット２３は、電動送風機２１の保護を目的として電動送風機２１に異物が侵入しないように設けられている。   As shown in FIG. 4, the electric blower 21 is housed and disposed in the electric blower storage chamber 20 in the main body 1. The electric blower 21 generates suction air for sucking dust. A filter unit 23 covered and held by the filter cover 11 is disposed upstream of the air path of the electric blower 21. The filter unit 23 is provided so that foreign matter does not enter the electric blower 21 for the purpose of protecting the electric blower 21.

電動送風機２１は空気を吸引するためにモーター（図示せず）により高速で羽根（図示せず）を回転させている。このため、電動送風機２１は、もしも異物を吸込んでしまうと羽根（図示せず）に絡まる等して回転が落ち性能が低下したり、硬い異物では羽根（図示せず）が変形や損傷するなどして性能が低下したり、又は完全に回転が停止して故障したりする可能性がある。このような事態を避けるため、電動送風機２１は、フィルターユニット２３によって保護されている。   The electric blower 21 rotates blades (not shown) at high speed by a motor (not shown) in order to suck air. For this reason, if the electric blower 21 sucks in the foreign matter, the electric blower 21 becomes entangled with the blade (not shown) and the rotation falls and the performance is deteriorated, or the hard foreign matter causes the blade (not shown) to be deformed or damaged. As a result, there is a possibility that the performance is deteriorated or the rotation is completely stopped and a failure occurs. In order to avoid such a situation, the electric blower 21 is protected by the filter unit 23.

さらに、本体１内には操作部６ｄからの入力により電動送風機２１の駆動等を制御するための制御基板２２等が配設されている。   Further, a control board 22 for controlling driving of the electric blower 21 and the like by an input from the operation unit 6d is disposed in the main body 1.

集塵器８は、吸引された空気に含まれる塵埃を捕集するためのものである。塵埃を捕集する方式としては、塵埃を含んだ空気から遠心力により塵埃と空気とを分離するサイクロン式や、塵埃を含んだ空気を通気性のある紙袋体に通過させ塵埃を捕集する紙パック式等があるが、本発明の実施の形態は塵埃の捕集方式に限定されるものではなく、捕集方式は適宜選択可能である。   The dust collector 8 is for collecting dust contained in the sucked air. As a method of collecting dust, a cyclone type that separates dust and air from dust-containing air by centrifugal force, or paper that passes dust-containing air through a breathable paper bag body and collects dust Although there are a pack type and the like, the embodiment of the present invention is not limited to the dust collection method, and the collection method can be appropriately selected.

集塵器８は、上ケース２の吸気管５と排気管１８とに挟まれた箇所に、吸気管５と排気管１８と同様に傾斜に沿って着脱自在に取り付けられている。集塵器８にはレバー（図示せず）と本体係止手段（図示せず）が設けられていて、レバーを操作すると本体１との係止状態が解除され本体１から分離可能となる。   The dust collector 8 is detachably attached to the portion of the upper case 2 sandwiched between the intake pipe 5 and the exhaust pipe 18 along the inclination similarly to the intake pipe 5 and the exhaust pipe 18. The dust collector 8 is provided with a lever (not shown) and a main body locking means (not shown). When the lever is operated, the locked state with the main body 1 is released and the main body 1 can be separated.

それから集塵器８は、図１、図５に示すように吸気管５側に突出した吸引口１５を有しており、吸気管５の他端側に設けられた流出口１４と着脱自在に接続され吸気管５と集塵器８の空気経路が連通するようになっている。   Then, the dust collector 8 has a suction port 15 protruding toward the intake pipe 5 as shown in FIGS. 1 and 5, and is detachable from an outlet 14 provided on the other end side of the intake pipe 5. The intake pipe 5 and the air path of the dust collector 8 are connected to communicate with each other.

また、集塵器８は、前述したように空気排出部１６を有しており、上ケース２に取付けられたフィルターカバー１１に設けられた連通口１７と接続され、集塵器８と本体１の空気経路が連通するようになっていて、その空気経路の下流には前述のフィルターユニット２３、電動送風機収納室２０及び電動送風機２１が備えられている。   Moreover, the dust collector 8 has the air discharge part 16 as mentioned above, is connected with the communication port 17 provided in the filter cover 11 attached to the upper case 2, and the dust collector 8 and the main body 1 are connected. The air path is communicated, and the filter unit 23, the electric blower storage chamber 20, and the electric blower 21 are provided downstream of the air path.

さらに集塵器８にはハンドル１２が設けられている。このハンドル１２は集塵器８が本体１から分離されている場合の移動に使用されるが、集塵器８の本体１への取付け面側と反対側に設けられていて、集塵器８が本体１に取付けられている場合には本体１移動用のハンドルとしても使用される兼用ハンドルとなっている。   Further, the dust collector 8 is provided with a handle 12. The handle 12 is used for movement when the dust collector 8 is separated from the main body 1. However, the handle 12 is provided on the side opposite to the mounting surface side of the dust collector 8 to the main body 1. Is attached to the main body 1, it is a combined handle that is also used as a handle for moving the main body 1.

ここで空気の流れを説明すると、電動送風機２１を駆動させることで吸引風が発生し塵埃を含んだ空気が図１に示す吸込具６ｆから吸引される。吸引された塵埃を含んだ空気はホース体６を通り、ホース体接続部４から流入口１３で連結された吸気管５を経由し吸気管５の流出口１４から集塵器８の吸引口１５へ流れる。   Here, the flow of air will be described. When the electric blower 21 is driven, suction air is generated and air containing dust is sucked from the suction tool 6f shown in FIG. The sucked air containing dust passes through the hose body 6, passes through the intake pipe 5 connected from the hose body connection portion 4 at the inlet 13, and flows from the outlet 14 of the intake pipe 5 to the suction port 15 of the dust collector 8. To flow.

集塵器８において塵埃が捕集され取り除かれた空気は、空気排出部１６を通りフィルターカバー１１に設けられた連通口１７から本体１に送られ、フィルターユニット２３を通過し電動送風機２１を経由して制御基板２２等を冷却した後、本体１内の空気経路（図示せず）を通過して排気管１８（図３参照）へ送られ、排気管１８に設けられた排気口１９（図３参照）から本体１外へ排出されるようになっている。   The air collected and removed by the dust collector 8 is sent to the main body 1 from the communication port 17 provided in the filter cover 11 through the air discharge portion 16, passes through the filter unit 23, and passes through the electric blower 21. Then, after cooling the control board 22 and the like, the air passes through an air path (not shown) in the main body 1 and is sent to the exhaust pipe 18 (see FIG. 3), and an exhaust port 19 (see FIG. 3) provided in the exhaust pipe 18 3) to the outside of the main body 1.

フィルターカバー１１は図６に示すように、本体１の後側において、樹脂成形で形成された連結部材２４によって、本体１の上部を構成する上ケース２と連結されている。連結状態を詳しく説明すると、図１０に示すように連結部材２４は、上ケース２に設けられた連結部材保持部３４に樹脂成形品の弾性で圧入するようにして爪掛け部３５で保持されている。   As shown in FIG. 6, the filter cover 11 is connected to the upper case 2 constituting the upper portion of the main body 1 by a connecting member 24 formed by resin molding on the rear side of the main body 1. The connecting state will be described in detail. As shown in FIG. 10, the connecting member 24 is held by the claw hook 35 so as to be press-fitted into the connecting member holding part 34 provided in the upper case 2 by the elasticity of the resin molded product. Yes.

フィルターカバー１１は、連結部材２４に設けられた回動軸受け部３６に、フィルターカバー１１に一体的に設けられた回動軸３２を圧入するようにして回動自在に保持されていて、図７（ｂ）に示すように回動軸３２を中心に後方へ向かって約９０度の角度で開放するようになっている。   The filter cover 11 is rotatably held so as to press-fit a rotation shaft 32 provided integrally with the filter cover 11 into a rotation bearing portion 36 provided on the connecting member 24. FIG. As shown in (b), the opening is made at an angle of about 90 degrees toward the rear with the rotation shaft 32 as the center.

連結部材２４を使用せず、上ケース２にフィルターカバー１１の回動軸３２を保持する受け部を一体的に設けることも可能であるが、上ケース２とフィルターカバー１１とは外観を構成する部品でもあり、剛性を優先して材料を選択すると外観の美しさが低下してしまう。   Although the connecting member 24 is not used, the upper case 2 can be integrally provided with a receiving portion for holding the rotating shaft 32 of the filter cover 11. However, the upper case 2 and the filter cover 11 constitute an appearance. It is also a part, and when the material is selected with priority given to rigidity, the beauty of the appearance deteriorates.

また、外観の美しさを優先すると耐磨耗性の高い材料を選択し難いということもある。従って、上ケース２とフィルターカバー１１との外観の美しさ確保と、回動軸の受け部の強度、剛性確保、耐磨耗性確保等とをそれぞれ考慮すると、連結部材２４を強度、剛性、耐磨耗性の高い材料で形成した別部品として、上ケース２とフィルターカバー１１とを連結することが望ましい。さらに別部品とした連結部材２４が目立たないようにフィルターカバー１１等の色を変更することも可能である。そうすることで、上ケース２とフィルターカバー１１の外観の美しさを確保したまま、強度、剛性、耐磨耗性も確保した耐久性の高い連結構造が実現可能となる。   In addition, when the appearance is prioritized, it may be difficult to select a material with high wear resistance. Therefore, considering the beauty of the outer appearance of the upper case 2 and the filter cover 11 and the strength, rigidity, and wear resistance of the receiving portion of the rotating shaft, respectively, the connecting member 24 has the strength, rigidity, It is desirable to connect the upper case 2 and the filter cover 11 as a separate part formed of a material with high wear resistance. Further, it is possible to change the color of the filter cover 11 or the like so that the connecting member 24 as a separate part does not stand out. By doing so, it is possible to realize a highly durable connection structure that ensures the strength, rigidity, and wear resistance while ensuring the beautiful appearance of the upper case 2 and the filter cover 11.

なお、本発明の実施の形態では図６のように連結部材２４が２つ設けられた例を示したが、連結部材２４の使用数は２つに限定されるものではなく、設定されたフィルターカバー１１の大きさにより１つでも３つでも仕様にあわせて使用数は適宜、選択可能である。   In the embodiment of the present invention, an example in which two connecting members 24 are provided as shown in FIG. 6 is shown. However, the number of connecting members 24 used is not limited to two. Depending on the size of the cover 11, the number of use can be selected as appropriate according to the specifications, either one or three.

それから、フィルターカバー１１には、図７（ａ）、図８に示すように本体１の上部を構成する上ケース２と連結されている側と反対側の端部に２個一対の係止手段２５が設けられている。フィルターカバー１１は、係止手段２５のそれぞれが、図７（ｂ）に示す上ケース２に設けられた係止部２６と係合することで、上ケース２に係止されている。   Then, as shown in FIGS. 7A and 8, the filter cover 11 has two pairs of locking means at the end opposite to the side connected to the upper case 2 constituting the upper portion of the main body 1. 25 is provided. The filter cover 11 is locked to the upper case 2 by engaging each of the locking means 25 with a locking portion 26 provided in the upper case 2 shown in FIG.

図９（ａ）により係止構造を詳しく説明すると、係止手段２５は係止解除ボタン２８と係止軸部３０とを一体的に備えており、係止手段２５の係止軸部３０は、フィルターカバー１１に一体的に設けられた係止軸受け部２９に摺動自在に挿入されている。   The locking structure will be described in detail with reference to FIG. 9A. The locking means 25 is integrally provided with a locking release button 28 and a locking shaft part 30, and the locking shaft part 30 of the locking means 25 is The filter cover 11 is slidably inserted into a locking bearing portion 29 provided integrally with the filter cover 11.

係止解除ボタン２８の裏側と固定部材３７との間には略Ｖ字上に曲げられた板バネ２７が設けられていて、この板バネ２７の付勢力により係止手段２５に係止方向Ｘの力が働く。係止軸部３０は、係止軸受け部２９から３乃至５ｍｍ程度長くなっているので、板バネ２７の付勢力により係止軸部３０の先端部が係止軸受け部２９の端部から３乃至５ｍｍ程度突出するようになっている。   A leaf spring 27 bent substantially in a V shape is provided between the back side of the latch release button 28 and the fixing member 37. The biasing force of the leaf spring 27 causes the latching means 25 to lock in the locking direction X. The power of work. Since the locking shaft portion 30 is about 3 to 5 mm longer than the locking bearing portion 29, the distal end portion of the locking shaft portion 30 is 3 to 5 mm from the end portion of the locking bearing portion 29 due to the urging force of the leaf spring 27. It protrudes about 5 mm.

同様に係止解除ボタン２８も板バネ２７の付勢力によりフィルターカバー１１に設けられた開口から突出するようになっている。係止解除ボタン２８の開口からの突出寸法は係止軸部３０の先端部が係止軸受け部２９の端部から突出する最大寸法以上、例えば５ｍｍ突出している場合は５ｍｍ以上となるように設定しており、これを係止解除ボタン２８の動作寸法としている。   Similarly, the lock release button 28 protrudes from the opening provided in the filter cover 11 by the urging force of the leaf spring 27. The protruding dimension of the locking release button 28 from the opening is set to be not less than the maximum dimension at which the tip of the locking shaft 30 protrudes from the end of the locking bearing 29, for example, 5 mm when protruding 5 mm. This is the operation dimension of the lock release button 28.

前述の板バネ２７の付勢力により係止軸受け部２９の端部から３乃至５ｍｍ程度突出した係止軸部３０の先端部が、上ケース２に設けられた係止部２６に入り込むことで、フィルターカバー１１と上ケース２の間にフィルターユニット２３を収めるようにしてフィルターカバー１１と上ケース２が係止された状態となり固定される（図４参照）。   The leading end portion of the locking shaft portion 30 that protrudes about 3 to 5 mm from the end portion of the locking bearing portion 29 by the urging force of the plate spring 27 enters the locking portion 26 provided in the upper case 2. The filter cover 11 and the upper case 2 are locked and fixed so that the filter unit 23 is accommodated between the filter cover 11 and the upper case 2 (see FIG. 4).

その後、掃除機１００を使用するときには集塵器８を必ず取付けることになるが、もしフィルターカバー１１と上ケース２を係止することを忘れていたとしても集塵器８を取付けることで係止されるようになっている。   After that, when using the vacuum cleaner 100, the dust collector 8 must be attached, but even if you forget to lock the filter cover 11 and the upper case 2, the dust collector 8 can be locked. It has come to be.

図１１（ａ）〜（ｄ）は係止手段２５周辺断面の要部を拡大した係止手段の動作図である。図１１（ａ）に示すように係止軸部３０の先端部の、係止部２６の方向に向かう下側には、傾斜形状部３１が設けられている。係止解除ボタン２８を操作しない状態でフィルターカバー１１を係止方向Ｙの方向へ押し込んでいくと、この傾斜形状部３１が係止部２６が設けられている側壁３８の角部３９に接触するようになる。   FIGS. 11A to 11D are operation diagrams of the locking means in which the main part of the section around the locking means 25 is enlarged. As shown in FIG. 11A, an inclined shape portion 31 is provided on the lower side of the distal end portion of the locking shaft portion 30 toward the locking portion 26. When the filter cover 11 is pushed in the locking direction Y without operating the locking release button 28, the inclined portion 31 comes into contact with the corner 39 of the side wall 38 where the locking portion 26 is provided. It becomes like this.

接触した状態から、さらにフィルターカバー１１を押し込むと、図１１（ｂ）のように板バネ２７の付勢力に抗しながら、係止部２６が設けられている側壁３８の角部３９を、傾斜形状部３１が滑り、係止手段２５は、板バネ２７の付勢力に抗しながら係止解除方向へ動いく。そして、図１１（Ｃ）のように係止軸部３０の先端部が、側壁３８と接触しながら係止方向へ押し込まれていく。   When the filter cover 11 is further pushed in from the contacted state, the corner portion 39 of the side wall 38 provided with the locking portion 26 is inclined while resisting the urging force of the leaf spring 27 as shown in FIG. The shape portion 31 slides, and the locking means 25 moves in the locking release direction while resisting the urging force of the leaf spring 27. Then, as shown in FIG. 11C, the distal end portion of the locking shaft portion 30 is pushed in the locking direction while contacting the side wall 38.

そして係止軸部３０が係止部２６の設けてられている箇所にくると、図１１（ｄ）のように板バネ２７の付勢力により係止軸部３０が係止部２６に入り込むようになり、フィルターカバー１１と上ケース２が係止された状態となる。   When the locking shaft portion 30 comes to the place where the locking portion 26 is provided, the locking shaft portion 30 enters the locking portion 26 by the urging force of the leaf spring 27 as shown in FIG. Thus, the filter cover 11 and the upper case 2 are locked.

このようにフィルターカバー１１を押し込むとフィルターカバー１１と上ケース２が係止されるようになるが、図１０に示すように集塵器８には押し込みリブ３３が設けられている。押し込みリブ３３は、集塵器８が取り付いた状態において、フィルターカバー１１の係止手段２５が設けられている近傍の角部に上方から接する位置に、設けられている。   Thus, when the filter cover 11 is pushed in, the filter cover 11 and the upper case 2 are locked, but the dust collector 8 is provided with push ribs 33 as shown in FIG. The push-in rib 33 is provided at a position in contact with the corner portion in the vicinity where the locking means 25 of the filter cover 11 is provided from above in a state where the dust collector 8 is attached.

よって、フィルターカバー１１が係止されていない状態で集塵器８を取付けようとすると、取付けの途中で押し込みリブ３３がフィルターカバー１１の係止手段２５が設けられている近傍の角部と接触することになるので、押し込みリブ３３によってフィルターカバー１１が係止方向へ押し込まれることになる。   Therefore, if the dust collector 8 is to be mounted in a state where the filter cover 11 is not locked, the pushing rib 33 contacts the corner portion in the vicinity where the locking means 25 of the filter cover 11 is provided during the mounting. Therefore, the filter cover 11 is pushed in the locking direction by the pushing rib 33.

そうすると、係止手段２５は前述のような構成となっているので、フィルターカバー１１が係止されていなくても、使用の際に集塵器８を取り付ければ、集塵器８を取付ける動作の中でフィルターカバー１１も係止されるようになり、集塵器８が本体１に取り付けられるのとほぼ同じタイミングで簡単で確実にフィルターカバー１１が係止されるようになっている。   Then, since the locking means 25 has the above-described configuration, even if the filter cover 11 is not locked, if the dust collector 8 is attached at the time of use, the operation of attaching the dust collector 8 is performed. Among them, the filter cover 11 is also locked, and the filter cover 11 is easily and reliably locked at almost the same timing as when the dust collector 8 is attached to the main body 1.

なお、ここではフィルターカバー１１の係止をしていない（忘れた）場合の集塵器８の取付けによりフィルターカバー１１が係止される説明をしたが、前述のような構成となっているので集塵器８を取付ける前にフィルターカバー１１を手できちんと係止する際も、フィルターカバー１１を押し込むことで簡単に係止させることができる。   Here, the filter cover 11 is described as being locked by attaching the dust collector 8 when the filter cover 11 is not locked (forgotten). Even when the filter cover 11 is properly locked by hand before the dust collector 8 is attached, the filter cover 11 can be easily locked by pushing it in.

前述のように係止された状態からフィルターカバー１１を開放する時には、板バネ２７の付勢力に抗して係止方向Ｘと反対の方向へ係止解除ボタン２８を操作する。但し、係止解除ボタン２８は２個一対で独立して動作するように設けられているので片方だけ操作しても片方しか係止状態を解除できない。そのため、両方から、係止解除ボタン２８を指等で摘まむように同時に操作をする。   When the filter cover 11 is released from the locked state as described above, the lock release button 28 is operated in the direction opposite to the lock direction X against the urging force of the leaf spring 27. However, since the lock release buttons 28 are provided so as to operate independently as a pair, only one of them can be released from the locked state. Therefore, from both sides, the operation is simultaneously performed so that the lock release button 28 is grasped with a finger or the like.

すると、それによりそれぞれの係止軸部３０が係止軸受け部２９の中を摺動し、係止軸部３０の先端部が係止部２６から抜ける方向へ移動する。係止軸部３０の先端部と係止部２６との係止寸法は、係止軸部３０の先端部が係止軸受け部２９の端部から突出した３乃至５ｍｍ程度であるが、前述のように、係止解除ボタン２８の動作寸法を、係止軸部３０の先端部が係止軸受け部２９の端部から突出する最大寸法以上、例えば５ｍｍ突出している場合は５ｍｍ以上、としているので確実に解除される。   As a result, the respective locking shaft portions 30 slide in the locking bearing portions 29, and the distal end portions of the locking shaft portions 30 move in the direction in which they are removed from the locking portions 26. The locking dimension between the distal end portion of the locking shaft portion 30 and the locking portion 26 is about 3 to 5 mm in which the distal end portion of the locking shaft portion 30 protrudes from the end portion of the locking bearing portion 29. As described above, the operation dimension of the locking release button 28 is set to be equal to or larger than the maximum dimension in which the tip end portion of the locking shaft portion 30 protrudes from the end portion of the locking bearing portion 29, for example, 5 mm or more when protruding 5 mm. It is released reliably.

解除された状態から係止解除ボタン２８を摘まんだまま上に引き上げれば、図７（ｂ）に示すように、フィルターカバー１１が回動軸３２を中心に後方へ向かって約９０度の角度で簡単に開放でき、フィルターユニット２３が取り出せるようになる。   If the lock release button 28 is grasped and lifted up from the released state, the filter cover 11 is about 90 degrees rearward about the rotation shaft 32 as shown in FIG. 7B. It can be easily opened at an angle, and the filter unit 23 can be taken out.

ここまでフィルターカバー１１の係止と解除とについて説明してきたが、集塵器８が取付けられると、図５のようにフィルターカバー１１に設けられた係止手段２５の係止解除ボタン２８は、集塵器８に覆われるようになる。よって集塵器８が取付けられた状態では、係止解除ボタン２８の操作はできない。従って、掃除機１００を使用中に誤ってフィルターカバー１１が開放されてしまうことがないので、使用者の誤操作を防止でき安全に掃除機１００を使用することができる。   Up to this point, the lock and release of the filter cover 11 has been described. When the dust collector 8 is attached, the lock release button 28 of the lock means 25 provided on the filter cover 11 as shown in FIG. The dust collector 8 is covered. Therefore, in a state where the dust collector 8 is attached, the lock release button 28 cannot be operated. Therefore, since the filter cover 11 is not accidentally opened while the cleaner 100 is in use, it is possible to prevent a user's erroneous operation and to use the cleaner 100 safely.

さらに、前述したようにフィルターカバー１１に保持されているフィルターユニット２３は電動送風機２１の保護を目的として電動送風機２１に異物が侵入しないように設けられており、フィルターユニット２３を保持するフィルターカバー１１が確実に係止されるので電動送風機２１の性能低下や故障を防止することができ、電動送風機２１の能力を維持することができる。   Further, as described above, the filter unit 23 held by the filter cover 11 is provided so as to prevent foreign matter from entering the electric blower 21 for the purpose of protecting the electric blower 21, and the filter cover 11 holding the filter unit 23. Is reliably locked, so that the performance deterioration and failure of the electric blower 21 can be prevented, and the capacity of the electric blower 21 can be maintained.

次に、フィルターカバー１１には図１２（ａ）、（ｂ）に示すようにホース体６の保持部５０が設けられている。図１２（ａ）は本発明の実施の形態に係る電気掃除機のフィルターカバー１１に設けられた保持部５０に、硬質延長管部６ｅの挿入片６ｇを挿入した状態の側面図、図１２（ｂ）は図１２（ａ）の保持部５０近傍で切断した側方断面図である。   Next, the filter cover 11 is provided with a holding portion 50 for the hose body 6 as shown in FIGS. 12A is a side view showing a state in which the insertion piece 6g of the hard extension tube portion 6e is inserted into the holding portion 50 provided in the filter cover 11 of the vacuum cleaner according to the embodiment of the present invention, FIG. FIG. 12B is a side sectional view cut in the vicinity of the holding portion 50 in FIG.

保持部５０はフィルターカバー１１とは別体の、樹脂成形で形成された部品であり、フィルターカバー１１の回動軸３２側（本体１の後側）にネジ５１で固定されている。保持部５０は、図１２（ａ）のように掃除中にホース体６を床に置くことなく保持しておくためのものである。   The holding part 50 is a part formed by resin molding, which is separate from the filter cover 11, and is fixed to the rotating shaft 32 side (rear side of the main body 1) of the filter cover 11 with screws 51. The holding part 50 is for holding the hose body 6 without placing it on the floor during cleaning as shown in FIG.

保持部５０は図１２（ｂ）に示すように断面形状がコの字をしており、そこにホース体６の硬質延長管部６ｅに設けられたＬ字形状の挿入片６ｇを挿入するようになっている。挿入するたびに、挿入片６ｇは保持部５０に衝撃を与えることになるが、前述したようにフィルターカバー１１は外観を構成する部品でもあり、剛性を優先して材料を選択すると外観の美しさが低下してしまう。そのため、強度、剛性確保、耐磨耗性確保等を考慮し、保持部５０は別体となっている。また、使用者が挿入し易くなるようフィルターカバー１１や他の部品と保持部５０との色を変えることで使用者の目安としている。   As shown in FIG. 12B, the holding portion 50 has a U-shaped cross section, and an L-shaped insertion piece 6g provided on the hard extension tube portion 6e of the hose body 6 is inserted therein. It has become. Each time it is inserted, the insertion piece 6g gives an impact to the holding portion 50. However, as described above, the filter cover 11 is also a component constituting the appearance. Will fall. Therefore, the holding part 50 is a separate body in consideration of securing strength, rigidity, wear resistance, and the like. In addition, the color of the filter cover 11 and other parts and the holding unit 50 is changed so that the user can easily insert it, thereby providing a guide for the user.

このようにすることで清掃中に少しの間、別の用事を済ませたい状況が発生しても、わざわざホース体６を床に置く必要がないので、腰や膝を曲げてホース体６を拾い上げることなく直ぐに再びホース体６を手に取ることができる。従って、使用者がホース体６を床から拾い上げる煩わしさを解消することができ、使用者の腰や膝に負担を掛けることを少なくすることができる。   In this way, even if there is a situation where it is desired to complete another task for a while during cleaning, it is not necessary to put the hose body 6 on the floor. Therefore, the waist and knees are bent and the hose body 6 is picked up. The hose body 6 can be picked up again immediately without any problems. Therefore, the troublesomeness of the user picking up the hose body 6 from the floor can be eliminated, and the burden on the user's waist and knees can be reduced.

なお、本実施の形態では保持部５０をフィルターカバー１１の回動軸３２側（本体１の後側）に設ける構成で説明しているが、図１３（ａ）のように側面方向に設けてもよく、側面方向にネジ座を設けておけばネジ５１を取り外すことでフィルターカバー１１の回動軸３２側から側面方向に取付け位置を移動、変更することが可能となる。ネジ１本での取り外しで移動、変更可能であるので、使用者がドライバー等の工具を使用することで自分の使い勝手の良い位置へ移動、変更させることも容易である。   In the present embodiment, the holding portion 50 is described as being provided on the rotating shaft 32 side (rear side of the main body 1) of the filter cover 11, but it is provided in the side surface direction as shown in FIG. If the screw seat is provided in the side surface direction, the mounting position can be moved and changed in the side surface direction from the rotation shaft 32 side of the filter cover 11 by removing the screw 51. Since it can be moved and changed by removing with one screw, it is easy for the user to move and change to a convenient position by using a tool such as a screwdriver.

また、保持部５０は１箇所に限られるものではなく、図１３（ｂ）のようにフィルターカバー１１の回動軸３２側と側面方向の両方のように複数設けてもよく、複数設けることによって使用者の利便性が向上する。   Further, the holding portion 50 is not limited to one place, and a plurality of holding portions 50 may be provided on both the rotating shaft 32 side and the side surface direction of the filter cover 11 as shown in FIG. User convenience is improved.

さらに、本実施の形態では硬質延長管部６ｅに挿入片６ｇを設けた例を示したが、挿入片６ｇは、吸込具６ｆや把持部６ｃ等に設けても良く、ホース体６の構成に合わせ、硬質延長管部６ｅ、吸込具６ｆや把持部６ｃのいずれか、又はそれらの全てに設けても、同様に清掃中に少しの間、別の用事を済ませたい状況が発生した場合に、わざわざホース体６を床に置く必要がなく、直ぐに再びホース体６を手に取ることができ使用者がホース体６を床から拾い上げる煩わしさを解消することができる。   Furthermore, although the example which provided the insertion piece 6g in the hard extension pipe | tube part 6e was shown in this Embodiment, the insertion piece 6g may be provided in the suction tool 6f, the holding part 6c, etc., and is the structure of the hose body 6. In addition, even if it is provided in any of the hard extension pipe part 6e, the suction tool 6f and the grip part 6c, or all of them, when a situation where another task needs to be completed during cleaning is generated, There is no need to bother to place the hose body 6 on the floor, and the hose body 6 can be picked up again immediately and the trouble of the user picking up the hose body 6 from the floor can be eliminated.

以上のように本発明の実施の形態においては、フィルターカバー１１に本体１へ係止する係止手段２５と係止状態の解除操作をする係止解除ボタン２８とを備えたので、フィルターカバー１１を弾性変形させることなく本体１に係止させることができる。係止解除ボタン２８を操作すると係止手段２５が解除されるようにしたので、フィルターカバー１１を弾性変形させないので、フィルターカバー１１の係止解除が安全で容易となり作業性が向上する。またこれにより、係止と解除とを繰り返すことに対する、フィルターカバー１１の耐久性を向上させることができる。   As described above, in the embodiment of the present invention, the filter cover 11 is provided with the locking means 25 for locking to the main body 1 and the lock release button 28 for releasing the lock state. Can be locked to the main body 1 without being elastically deformed. Since the locking means 25 is released when the locking release button 28 is operated, the filter cover 11 is not elastically deformed, so that the locking of the filter cover 11 is safe and easy, and the workability is improved. Thereby, the durability of the filter cover 11 against repeated locking and releasing can be improved.

また、フィルターカバー１１を連結する部品を、強度、剛性、耐磨耗性の高い材料で形成した別部品としたので、フィルターカバー１１を繰り返しの開閉する際の耐久性が向上する。それから、掃除中にはフィルターカバー１１が集塵器８に覆われるようになっているので、掃除中に誤ってフィルターカバー１１を開放してしまうことがなく使用者の誤操作を防止することができ、安全に掃除機１００を使用することができる。   In addition, since the component for connecting the filter cover 11 is a separate component formed of a material having high strength, rigidity, and wear resistance, durability when the filter cover 11 is repeatedly opened and closed is improved. Then, since the filter cover 11 is covered with the dust collector 8 during cleaning, the filter cover 11 is not accidentally opened during cleaning, and the user's erroneous operation can be prevented. The vacuum cleaner 100 can be used safely.
