Description

本発明は、紙袋式集塵フィルタを使用する電気掃除機に関する。   The present invention relates to a vacuum cleaner using a paper bag type dust collecting filter.

最近の電気掃除機は、紙袋式の集塵フィルタを使用する形態ものが主流になっている。   Recent vacuum cleaners are mainly in the form of using a paper bag type dust collection filter.

紙袋式集塵フィルタを使用する電気掃除機は、捕獲した塵によって紙袋内が満杯になったときには集塵フィルタを取り外して使い捨て(新しい集塵フィルタと交換)することができるので、取り扱いが便利である。   The vacuum cleaner that uses the paper bag type dust collection filter is convenient to handle because the dust collection filter can be removed and disposable (replaced with a new dust collection filter) when the inside of the paper bag is full due to the captured dust. is there.

しかしながら、紙袋式集塵フィルタは、紙袋内が塵で満杯になる前から濾過面に付着した微細な塵によって目詰り現象を起こして通気抵抗が増加することから、所定の時機に集塵フィルタに振動を与えて濾過面に付着した微細塵を紙袋内の底部に震い落すようにして除塵する除塵機構を設けることが提案されている。   However, a paper bag type dust collection filter causes a clogging phenomenon due to fine dust adhering to the filtration surface before the inside of the paper bag is filled with dust and increases the airflow resistance. It has been proposed to provide a dust removal mechanism that removes the fine dust adhering to the filtration surface by applying vibration to the bottom of the paper bag.

除塵機構は、紙袋式集塵フィルタの外周面に作用する除塵子を振動させることによって該紙袋式集塵フィルタの内面(濾過面)に付着した塵を震い落す構成であり、除塵子を振動させる除塵子駆動機構としては、電磁振動で振動させる構成の電磁式駆動機構や、電源コードの巻き取りに用いるコードリールの回転を伝達して振動させる構成のコードリール式駆動機構が提案されている。   The dust removal mechanism is configured to vibrate the dust attached to the inner surface (filtering surface) of the paper bag dust collection filter by vibrating the dust remover that acts on the outer peripheral surface of the paper bag dust collection filter. As the dust remover driving mechanism, an electromagnetic driving mechanism configured to vibrate by electromagnetic vibration and a cord reel driving mechanism configured to transmit and vibrate rotation of a cord reel used for winding a power cord are proposed. .

The shaken dust is again used in subsequent use (ventilation). It is desirable to prevent the air from adhering to the filtration surface and clogging.

また、除塵機構における除塵子駆動機構は、掃除機本体内の限られたスペースに簡単に取り付けて収容することができるように構成することが望まれる。   Further, it is desirable that the dust remover drive mechanism in the dust removal mechanism be configured so that it can be easily attached and accommodated in a limited space in the cleaner body.

Install in the chamber 11. That is, in a state where the posture to run the cleaner body 1 by the main wheel 5 and casters 6, part of the bellows 16b 2 of filtration paper bag 16b is positioned on both lateral side direction, it is folded so as rounding both ends open end closed's sealing edge 16b 3 is placed to fit to the dust collecting chamber 11 in a posture which is positioned in the vertical direction.

電動送風機室12内には、電動送風機18とコードリールユニット19と制御装置20を内蔵する。   In the electric blower chamber 12, an electric blower 18, a cord reel unit 19, and a control device 20 are incorporated.

電動送風機18は、集塵室11内の空気を通気窓8aを通して吸い出すように下ケース仕切り壁部8bに防振ゴム21を介して気密状態に接合させて取り付ける。   The electric blower 18 is attached to the lower case partition wall portion 8b in an airtight state via the anti-vibration rubber 21 so as to suck out the air in the dust collecting chamber 11 through the ventilation window 8a.

コードリールユニット19は、回転して電源コード22を巻き込み/巻き出しする巻き付けドラム23と、この巻き付けドラム23の両側端に設けたドラム側板24,25を備える。ドラム側板25の外周縁にはドラム側板歯車部25aを一体的に形成する。そして、このコードリールユニット19は、前記電動送風機18の横に位置させてドラム回転軸心が本体下ケース8の底面に対して平行で横向きの状態となるように設置する。   The cord reel unit 19 includes a winding drum 23 that rotates and winds / unwinds the power cord 22, and drum side plates 24 and 25 provided on both ends of the winding drum 23. A drum side plate gear portion 25 a is integrally formed on the outer peripheral edge of the drum side plate 25. The cord reel unit 19 is placed beside the electric blower 18 so that the drum rotation axis is parallel to the bottom surface of the main body lower case 8 and is in a horizontal state.

前記除塵子17を押圧する除塵子駆動機構を構成する除塵子駆動ユニット26の具体的な構成を図9および図10を参照して説明する。   A specific configuration of the dust remover drive unit 26 constituting the dust remover drive mechanism that presses the dust remover 17 will be described with reference to FIGS. 9 and 10.

除塵子駆動ユニット26は、前記コードリールユニット19の回転によって駆動されて回転する除塵子駆動ドラム27を備え、この除塵子駆動ドラム27を回転させることにより該除塵子駆動ドラム27の外周に設けた複数の接触子28によって除塵子17の後面を繰り返し押圧して該除塵子17を揺動させる構成であり、前記下ケース仕切り壁8における前記通気窓8aの下側で集塵室11内側に位置して前記除塵子17の下端部分に対向するように本体下ケース8の底部に設置するように固定し、支軸17b,17cを支点にして格子状枠体17aを揺動させるように駆動する。   The dust remover drive unit 26 includes a dust remover drive drum 27 that is driven to rotate by the rotation of the cord reel unit 19, and is provided on the outer periphery of the dust remover drive drum 27 by rotating the dust remover drive drum 27. The rear surface of the dust remover 17 is repeatedly pressed by a plurality of contacts 28 to swing the dust remover 17, and is located inside the dust collection chamber 11 below the ventilation window 8 a in the lower case partition wall 8. Then, it is fixed so as to be installed at the bottom of the main body lower case 8 so as to face the lower end portion of the dust remover 17, and is driven so as to swing the lattice frame 17a with the support shafts 17b and 17c as fulcrums. .

除塵子駆動ドラム27は、除塵子駆動ユニット基板29の内側に除塵子駆動ドラム軸支持部29a,29bを起立させ、この除塵子駆動ドラム軸支持部29a,29b間に前記除塵子駆動ドラム27を回転可能状態に支持する。除塵子駆動ドラム軸支持部29aの外側に延長した除塵子駆動ドラム軸30は、その外端部に除塵子駆動ドラム軸歯車31を備え、この除塵駆動ユニット26が掃除機本体1に組み付けられた状態で前記コードリールユニット19のドラム側板歯車部25aと噛み合ってドラム側板25の回転に従動して除塵子駆動ドラム軸30を回転させるように機能する。この除塵子ドラム駆動軸30は、除塵子駆動ドラム27内に位置させたワンウェイクラッチ(図示省略)を介して該除塵子駆動ドラム27と係合し、電源コード22を引き出すときのドラム側板25の回転に伴う除塵子駆動ドラム駆動軸30の回転を除塵子駆動ドラム27に伝達し、電源コード22を巻き込むときのドラム側板25の回転に伴う除塵子駆動ドラム駆動軸30の回転は除塵子駆動ドラム27に伝達しないように構成する。   The dust remover drive drum 27 raises dust remover drive drum shaft support portions 29a and 29b inside the dust remover drive unit substrate 29, and the dust remover drive drum 27 is placed between the dust remover drive drum shaft support portions 29a and 29b. Support in a rotatable state. The dust remover drive drum shaft 30 extended to the outside of the dust remover drive drum shaft support portion 29a is provided with a dust remover drive drum shaft gear 31 at the outer end thereof, and this dust removal drive unit 26 is assembled to the cleaner body 1. In this state, it functions to engage with the drum side plate gear portion 25a of the cord reel unit 19 and rotate the dust remover drive drum shaft 30 following the rotation of the drum side plate 25. The dust remover drum drive shaft 30 is engaged with the dust remover drive drum 27 via a one-way clutch (not shown) positioned in the dust remover drive drum 27, and the drum side plate 25 when the power cord 22 is pulled out. The rotation of the dust remover drive drum drive shaft 30 accompanying the rotation is transmitted to the dust remover drive drum 27, and the rotation of the dust remover drive drum drive shaft 30 accompanying the rotation of the drum side plate 25 when the power cord 22 is wound is the dust remover drive drum. 27 to prevent transmission.

除塵子駆動ドラム27の外周に設けた複数の接触子28は、それぞれ、基端部分を除塵子駆動ドラム27の外周に取り付け、除塵子駆動ドラム27の外周面に沿って回転方向の下流方向に徐々に離れて高くなるように傾き、後端部分を除塵子駆動ドラム27の外周面に向けて急峻に折り曲げて山形形状に形成した弾性板によって構成する。この接触子28の弾力の強さは、紙袋式集塵フィルタ16の濾過用紙袋16b内に塵埃がいっぱい(満杯)に入って該濾過用紙袋16bが強く膨らんで除塵子17の揺動に大きな抵抗が作用するときに撓んで除塵子駆動ドラム27に大きな回転抵抗が作用するのを避けることができる強さとする。これにより、電源コード22を引き出すときに過大な引き出し抵抗が発生するのを防止する。   The plurality of contacts 28 provided on the outer periphery of the dust remover drive drum 27 are each attached with a base end portion on the outer periphery of the dust remover drive drum 27 and along the outer peripheral surface of the dust remover drive drum 27 in the downstream direction of the rotation direction. It is configured by an elastic plate which is inclined so as to be gradually separated and becomes higher and the rear end portion is sharply bent toward the outer peripheral surface of the dust remover driving drum 27 to form a chevron shape. The contact 28 has a great elasticity because the filter paper bag 16b of the paper bag type dust collecting filter 16 is filled (filled) and the filter paper bag 16b swells strongly to greatly swing the dust remover 17. The strength is such that it can be avoided that a large rotational resistance acts on the dust remover drive drum 27 by bending when the resistance acts. This prevents an excessive pulling resistance from being generated when the power cord 22 is pulled out.

除塵子駆動ユニット基板29における前記除塵子駆動ドラム軸支持部29a,29bの外周端縁面29c,29dと該除塵子駆動ドラム軸支持部29a,29b間を結ぶ除塵子駆動ユニット基板29の両側の端縁面29eは、この除塵子駆動ユニット基板29を本体下ケース8の底壁から集塵室11に連なるように形成した除塵子駆動ユニット取付け窓8cに下側から挿入するように嵌着した状態で該本体下ケース8に当接して前記集塵室11の気密を保持するように機能し、除塵子駆動ドラム軸支持部29a,29b間の除塵子駆動ドラム27を集塵室11内の除塵子17の下端部分の後側に位置させる。また、前記通気窓8aの下側に位置するので、電動送風機18で吸引する気流の通路の外側に位置することになり、空気の流れを乱すことがなく、通気抵抗を増加させることがないという効果がある。   On both sides of the dust remover drive unit substrate 29 connecting the outer peripheral edge surfaces 29c, 29d of the dust remover drive drum shaft support portions 29a, 29b and the dust remover drive drum shaft support portions 29a, 29b in the dust remover drive unit substrate 29. The edge surface 29e is fitted so that the dust remover drive unit substrate 29 is inserted from below into a dust remover drive unit mounting window 8c formed so as to be connected to the dust collecting chamber 11 from the bottom wall of the lower case 8 of the main body. The dust collecting chamber 11 functions in such a manner as to abut against the lower case 8 of the main body to keep the dust collecting chamber 11 airtight, and the dust removing drive drum 27 between the dust remover driving drum shaft support portions 29a and 29b is placed in the dust collecting chamber 11. The dust remover 17 is positioned behind the lower end portion. Moreover, since it is located below the ventilation window 8a, it is located outside the passage of the air flow sucked by the electric blower 18, and does not disturb the air flow and does not increase the ventilation resistance. effective.

また、除塵子駆動ユニット基板29は、除塵子駆動ドラム軸支持部29a,29b間の前側部分の一部を本体内側に凹めるような湾曲部分29fに形成してキャスター6の一部を本体下ケース8の底部に収容するキャスター収容空間8dの一部を構成させる。この除塵子駆動ユニット基板29の湾曲部分29fは、除塵子駆動ユニット基板29の全体的な剛性を高めるようにも機能する。そして、この除塵子駆動ユニット基板29の両端部分には、取付けねじ貫通穴29g,29hを設ける。   Further, the dust remover drive unit substrate 29 is formed in a curved portion 29f in which a part of the front portion between the dust remover drive drum shaft support portions 29a and 29b is recessed inside the main body, and a part of the caster 6 is formed in the main body. A part of the caster accommodating space 8d accommodated in the bottom of the lower case 8 is configured. The curved portion 29 f of the dust remover drive unit substrate 29 also functions to increase the overall rigidity of the dust remover drive unit substrate 29. Then, attachment screw through holes 29 g and 29 h are provided at both ends of the dust remover drive unit substrate 29.

本体下ケース8への除塵子駆動ユニット26の取り付け方法を図10を参照して説明する。まず、底面を上向きにすることにより除塵子駆動ユニット取付け窓8cを上側に位置させた姿勢に本体下ケース8を置き、除塵子駆動ユニット26を下向きにして前記除塵子駆動ユニット取付け窓8cに嵌着して取付けねじ32,33によって本体下ケース8にねじ止め固定する。その際、除塵子駆動ユニット基板29における前記除塵子駆動ドラム軸支持部29a,29bの外周端縁面29c,29dおよび該除塵子駆動ドラム軸支持部29a,29b間を結ぶ除塵子駆動ユニット基板29の両側の端縁面29eと集塵室11内の気密を保持するための本体下ケース8との当接面の間には、除塵子駆動ユニットパッキン34を介在させる。この除塵子駆動ユニットパッキン34の介在は、予め、除塵子駆動ユニット基板29側または本体下ケース8側に取り付けた状態で除塵子駆動ユニット26を本体下ケース8の除塵子駆動ユニット取付け窓8cに嵌着することによって実現する。   A method of attaching the dust remover drive unit 26 to the main body lower case 8 will be described with reference to FIG. First, the main body lower case 8 is placed with the bottom face up so that the dust remover drive unit mounting window 8c is positioned on the upper side, and the dust remover drive unit 26 faces downward to fit into the dust remover drive unit mounting window 8c. Attach and fix to the lower case 8 with the mounting screws 32 and 33. At that time, the dust remover drive unit substrate 29 connecting the outer peripheral edge surfaces 29c, 29d of the dust remover drive drum shaft support portions 29a, 29b and the dust remover drive drum shaft support portions 29a, 29b in the dust remover drive unit substrate 29. A dust remover drive unit packing 34 is interposed between the contact surfaces of the edge surfaces 29e on both sides of the main body and the lower body case 8 for maintaining airtightness in the dust collection chamber 11. The dust remover drive unit packing 34 is interposed between the dust remover drive unit 26 and the dust remover drive unit mounting window 8c of the main body lower case 8 in a state where the dust remover drive unit packing 34 is previously attached to the dust remover drive unit substrate 29 side or the main body lower case 8 side. Realized by fitting.

また、除塵子駆動ドラム軸支持部29aと除塵子駆動ドラム軸30との気密は、除塵子駆動ドラム軸30に挾み込んだシールパッキング30aが集塵室11内側の負圧に引かれて除塵子駆動ドラム軸支持部29aに当接するようにして行う。なお、シールパッキング30aは、電源コード22を引き出すとき(集塵室11内に負圧が発生していないとき)には、除塵子駆動ドラム軸支持部29aとの間に0.2mm程度の隙間を発生し、掃除機使用時に集塵室11内に負圧が発生したときの漏れ気流による風圧によって撓んで除塵子駆動ドラム軸支持部29aに当接するように設ける。このように構成することにより、電源コード22を引き出すときのシールパッキング30aと除塵子駆動ドラム軸支持部29aの摩擦抵抗によって電源コード22が引き出し難くなるのを防止することができる。   Further, the airtightness between the dust remover drive drum shaft support portion 29a and the dust remover drive drum shaft 30 is determined by the seal packing 30a squeezed into the dust remover drive drum shaft 30 being pulled by the negative pressure inside the dust collecting chamber 11 to remove dust. This is performed in contact with the child drive drum shaft support portion 29a. When the power cord 22 is pulled out (when no negative pressure is generated in the dust collecting chamber 11), the seal packing 30a has a clearance of about 0.2 mm between the seal packing 30a and the dust remover drive drum shaft support 29a. Is provided so as to be bent by the wind pressure caused by the leaked air flow when a negative pressure is generated in the dust collecting chamber 11 when the cleaner is used, and to come into contact with the dust remover drive drum shaft support portion 29a. With this configuration, it is possible to prevent the power cord 22 from being easily pulled out due to the frictional resistance between the seal packing 30a and the dust remover drive drum shaft support portion 29a when the power cord 22 is pulled out.

主車輪5は、電動送風機室12の両側に位置させて本体下ケース8の外側に取り付ける。   The main wheels 5 are attached to the outside of the main body lower case 8 so as to be positioned on both sides of the electric blower chamber 12.

キャスター6は、本体下ケース8における集塵室11の底部を本体内側に凹めるように湾曲させて形成したキャスター収容空間8dに設置する。このキャスター6は、中心に取り付け穴6aを形成した車輪支持体6bと該車輪支持体6bの偏心位置に取り付けたキャスター車輪6cを備える。そして前記本体下ケース8における前記キャスター収容空間8dの中心に該本体下ケース8から突出させたキャスター支持軸8eを前記車輪支持体6bの取り付け穴6aに嵌入するように該車輪支持体6bを嵌着して取り付ける。   The caster 6 is installed in a caster housing space 8d formed by curving so that the bottom of the dust collection chamber 11 in the main body lower case 8 is recessed inward of the main body. The caster 6 includes a wheel support 6b having a mounting hole 6a formed at the center thereof, and a caster wheel 6c attached to an eccentric position of the wheel support 6b. Then, the wheel support body 6b is fitted so that the caster support shaft 8e protruding from the main body lower case 8 is inserted into the mounting hole 6a of the wheel support body 6b at the center of the caster housing space 8d in the main body lower case 8. Wear and attach.

制御装置20は、電源コード22から給電を受け、前記コードグリップ2cに設けた指示(運転)スイッチからの指示に従って電動送風機18の運転を制御する。   The control device 20 receives power from the power cord 22 and controls the operation of the electric blower 18 in accordance with an instruction from an instruction (operation) switch provided on the cord grip 2c.

このように構成した電気掃除機を使用するときには、掃除機本体1におけるホース嵌着部材14のホース差込口14aにホースユニット2の本体接続管2bを嵌着し、ホースユニット2のホースグリップ2cに延長管3を嵌着し、この延長管3の先に吸口44を嵌着し、掃除機本体1を横長にして主車輪5とキャスター6によって床面を走行するような姿勢にする。この状態で電源コード22を引き出して商用電源コンセントに接続する。   When using the thus configured electric vacuum cleaner, the main body connecting pipe 2b of the hose unit 2 is fitted into the hose insertion port 14a of the hose fitting member 14 in the vacuum cleaner main body 1, and the hose grip 2c of the hose unit 2 is fitted. The extension pipe 3 is fitted to the pipe, and the suction port 44 is fitted to the tip of the extension pipe 3 so that the main body 5 and the casters 6 run on the floor surface with the vacuum cleaner main body 1 being horizontally long. In this state, the power cord 22 is pulled out and connected to a commercial power outlet.

電源コード22を引き出すときに回転する巻き付けドラム23が回転してドラム側板25も回転することから、このドラム側板25に形成されているドラム側板歯車部25aと噛み合う除塵子駆動ドラム軸歯車31が回転して除塵子駆動ドラム軸30を回転させ、除塵子駆動ドラム27を回転駆動する。除塵子駆動ドラム27が回転すると、その外周面に取り付けた接触子28が除塵子17の後面を繰返し押圧して該除塵子17を揺動させる。   Since the winding drum 23 that rotates when the power cord 22 is pulled out rotates and the drum side plate 25 also rotates, the dust remover drive drum shaft gear 31 that meshes with the drum side plate gear portion 25a formed on the drum side plate 25 rotates. Then, the dust remover drive drum shaft 30 is rotated, and the dust remover drive drum 27 is rotationally driven. When the dust remover drive drum 27 rotates, the contact 28 attached to the outer peripheral surface repeatedly presses the rear surface of the dust remover 17 to swing the dust remover 17.

このとき、図11の(a)〜(c)に示すように、前の吸引掃除によって紙袋式集塵フィルタ16の濾過用紙袋16bが膨らんでその奥側面が除塵子17に接触していれば、除塵子駆動ドラム27の回転に伴う除塵子17の揺動に伴って濾過用紙袋16bも揺動(振動)することから、濾過用紙袋16bの濾過面の内面に付着した塵が震い落される。   At this time, as shown in FIGS. 11A to 11C, if the filter paper bag 16b of the paper bag type dust collecting filter 16 is inflated by the previous suction cleaning and the back side surface is in contact with the dust remover 17. Since the filter paper bag 16b also swings (vibrates) as the dust remover 17 swings as the dust remover drive drum 27 rotates, the dust adhering to the inner surface of the filter surface of the filter paper bag 16b shakes down. Is done.

ところで、この実施例1における紙袋式集塵フィルタ16は、集塵室11内において濾過用紙袋16bが縦長に伸びるように膨らんでいることから、除塵子17の揺動が濾過用紙袋16bにおいて目詰りし易い奥側面の壁に広く作用して該奥側壁を効果的に振動させて該奥側壁の内面に付着した塵を効率良く震い落すことができる。   By the way, since the paper bag type dust collecting filter 16 in the first embodiment swells in the dust collecting chamber 11 so that the filter paper bag 16b extends vertically, the dust remover 17 swings in the filter paper bag 16b. It acts on the wall on the back side surface that is easily clogged and effectively vibrates the back side wall, so that the dust adhering to the inner surface of the back side wall can be efficiently shaken off.

吸引清掃するためにホースグリップ2cに設けられた指示(運転)スイッチが押圧操作されると、この運転スイッチは制御装置20に運転信号を伝送し、この運転信号を受信した制御装置20は電動送風機18を運転する。運転状態になった電動送風機18は、集塵室11内の空気を吸い出して該集塵室11内の気圧を低下させ、紙袋式集塵フィルタ16における濾過用紙袋16b内の含塵空気が該濾過用紙袋16bによって濾過されながら集塵室11内に吸い出される。そして、濾過用紙袋16b内には、吸口4から塵を巻き込みながら吸い込まれた新たな含塵空気が延長管3,ホースユニット2を通してホース差込口14aから流入して順次に濾過される。   When an instruction (operation) switch provided on the hose grip 2c is pressed to perform suction cleaning, the operation switch transmits an operation signal to the control device 20, and the control device 20 that has received the operation signal receives the electric blower. Drive 18 The electric blower 18 in the operating state sucks out the air in the dust collecting chamber 11 to reduce the air pressure in the dust collecting chamber 11, and the dust-containing air in the filter paper bag 16 b in the paper bag type dust collecting filter 16 is It is sucked into the dust collecting chamber 11 while being filtered by the filter paper bag 16b. Then, new dust-containing air sucked in while dust is trapped from the suction port 4 flows into the filter paper bag 16b from the hose insertion port 14a through the extension tube 3 and the hose unit 2, and is sequentially filtered.

そして、吸引清掃を終了するためにホースグリップ2cに設けられた指示(停止)スイッチが押圧操作されると、この停止スイッチは制御装置20に停止信号を伝送し、この停止信号を受信した制御装置20は電動送風機18の運転を停止する。電源コード22をコードリールユニット19に巻き取らせて収納するときにドラム側板歯車部25aに噛み合って回転する除塵子駆動ドラム軸歯車31の回転は、除塵子駆動ドラム27には伝達されない。   When an instruction (stop) switch provided on the hose grip 2c is pressed to finish suction cleaning, the stop switch transmits a stop signal to the control device 20 and receives the stop signal. 20 stops the operation of the electric blower 18. When the power cord 22 is wound around and stored in the cord reel unit 19, the rotation of the dust remover drive drum shaft gear 31 that rotates while meshing with the drum side plate gear portion 25 a is not transmitted to the dust remover drive drum 27.

なお、ドラム側板歯車部25aと除塵子駆動ドラム軸歯車31の1段の平歯車の組み合わせで動力を伝達するようにしているので、2段の歯車伝達機構などに比べて歯車の噛み合いによる抵抗を小さくすることができる。   In addition, since the power is transmitted by the combination of the single-stage spur gear of the drum side plate gear portion 25a and the dust remover driving drum shaft gear 31, the resistance due to the meshing of the gear is smaller than that of the two-stage gear transmission mechanism. Can be small.

濾過用紙袋16b内が満杯になるように集塵した紙袋式集塵フィルタ16を新しい紙袋式集塵フィルタ16に交換するための出し入れは、前述したように、集塵室蓋10を起立させて集塵室11の上方を開放した状態で行うが、この実施例1における除塵子駆動ユニット26は集塵室11の下部に位置しているので、紙袋式集塵フィルタ16の出し入れ空間を大きく確保することができる。   In order to replace the paper bag type dust collection filter 16 that has collected dust so that the inside of the filter paper bag 16b is filled with a new paper bag type dust collection filter 16, the dust collection chamber lid 10 is raised as described above. Although the dust collection chamber 11 is opened upward, the dust remover drive unit 26 in the first embodiment is located in the lower portion of the dust collection chamber 11, so that a large space for the paper bag type dust collection filter 16 is secured. can do.

ここで、紙袋式集塵フィルタ16の除塵について、図12〜図16を参照して詳細に説明する。   Here, the dust removal of the paper bag type dust collecting filter 16 will be described in detail with reference to FIGS.

この実施例1において縦長状態に膨らむような姿勢に設置した紙袋式集塵フィルタ16の濾過用紙袋16bは、基本的には、図12に示すように、蛇腹16bが両横に位置して前後方向に伸び、封止縁部16bが上下方向に移動するように伸びて縦長形態となるように膨らんでその奥側壁面が除塵子17の前面に当接する。紙袋式集塵フィルタ16の濾過用紙袋16bの膨らみは、実際には、集塵室11の内面によって制約されることから、図2〜図4に示すように歪んだ形状になる。除塵子17の後側に下ケース仕切り壁部8bの通気窓8aが位置し、その対向位置に口紙16aの吸気窓16aが開口しているので、含塵空気は口紙16aの吸気窓16aから奥側壁面に向かって強く流れて該奥側壁に多く集塵される。比較的大きな塵は濾過用紙袋16bの最内側に位置する内側層に捕捉され、微細塵の多くは内側層を通過して中間層に捕捉されて該中間層に付着して該中間層を目詰りさせる。 Filtration bags 16b of bag type dust collector filter 16 in this example 1 was placed in position as to bulge portrait orientation, basically, as shown in FIG. 12, the bellows 16b 2 are located on both lateral longitudinal extending direction, the inner side wall bulges such that the elongated form extending to sealing edge 16b 3 is moved in the vertical direction comes into contact with the front surface of Jochiriko 17. Since the swelling of the filter paper bag 16b of the paper bag type dust collecting filter 16 is actually restricted by the inner surface of the dust collecting chamber 11, it has a distorted shape as shown in FIGS. Located aeration windows 8a of the lower case partition wall portion 8b on the rear side of Jochiriko 17, since the inlet window 16a 1 of the mouth paper 16a to the opposing position is open, the dust-containing air inlet window of the mouth paper 16a It flows strongly toward the back side wall surface from 16a 1 and a large amount of dust is collected on the back side wall. Relatively large dust is trapped by the inner layer located on the innermost side of the filter paper bag 16b, and most of the fine dust passes through the inner layer and is trapped by the intermediate layer and adheres to the intermediate layer. Clog.

このように集塵して膨らんだ濾過用紙袋16bの奥側壁面が除塵子17における格子状枠体17aの前面に接触した状態において、図13に示すように、除塵子17が繰り返し揺動して濾過用紙袋16bの奥側壁面が振動すると該奥側壁面に付着している塵は震い落されて濾過用紙袋16bの下方に大きく膨らんだ部分(封止縁部16b)に向かって落下する。比較的に大きな塵は内側層の内面に補足されていることから該内側層の内面に沿って落下し、中間層に補足されている微細塵は濾過用紙袋16bの振動によって内側層と中間層の間に発生する間隙に沿って落下する。そして、これらの塵が落下して溜る位置は、吸引清掃時の強い気流の中心から遠ざかった下方の位置となるので、震い落した塵が次の吸引清掃時の強い気流に巻き込まれて舞い上がって再び濾過用紙袋16bの奥側壁内面に付着するのを抑制(軽減)することができる。 In the state in which the back side wall surface of the filter paper bag 16b that has been collected and inflated is in contact with the front surface of the lattice frame 17a of the dust remover 17, the dust remover 17 repeatedly swings as shown in FIG. When the back wall surface of the filter paper bag 16b vibrates, the dust adhering to the back wall surface is shaken off and toward the portion (seal edge 16b 3 ) that swells greatly below the filter paper bag 16b. Fall. Since relatively large dust is captured by the inner surface of the inner layer, it falls along the inner surface of the inner layer, and the fine dust captured by the intermediate layer is caused by the vibration of the filter paper bag 16b. It falls along the gap generated between the two. And the position where these dusts fall and accumulate is the lower position away from the center of the strong air current at the time of suction cleaning, so the shaken dust is caught up in the strong air current at the next suction cleaning and soars Thus, it is possible to suppress (reduce) adhesion to the inner surface of the back side wall of the filter paper bag 16b again.

このような除塵において、紙袋式集塵フィルタ16の濾過用紙袋16b内で奥側壁面(内側層と中間層)に付着している比較的に小さな塵は各層の表面に沿って下方に落下(移動)することから、塵をより下方まで移動させるためには、濾過用紙袋16bの下方に位置する部位を大きく振動させることが望ましい、その点、この実施例1における除塵子17は、格子状枠体17aの上端部分を支点にして揺動可能に設置され、この除塵子17を揺動駆動する除塵子駆動ドラム27が集塵室11における後方の通気窓8aの下側に位置して前記格子状枠体17aの下端部分に作用して該格子状枠体17aの下端部分が大きく振れるように押圧駆動しているので、除塵に好ましい形態で濾過用紙袋16bを振動させることができる。   In such dust removal, relatively small dust adhering to the back side wall surface (inner layer and intermediate layer) in the filter paper bag 16b of the paper bag type dust collecting filter 16 falls down along the surface of each layer ( In order to move the dust further downward, it is desirable to vibrate the portion located below the filter paper bag 16b greatly. In that respect, the dust remover 17 in this embodiment 1 has a lattice shape. A dust remover driving drum 27 that is swingably installed with the upper end portion of the frame body 17a as a fulcrum is located below the rear ventilation window 8a in the dust collecting chamber 11 and is located above the dust collection chamber 11. The filter paper bag 16b can be vibrated in a form that is preferable for dust removal because it acts on the lower end portion of the grid-like frame body 17a and is pressed and driven so that the lower end portion of the grid-like frame body 17a shakes greatly.

因に、図14に示すように、濾過用紙袋16bが横長状態に膨らむような姿勢に紙袋式集塵フィルタ16を集塵室11内に設置すると、集塵した濾過用紙袋16bは、基本的には、図15に示すように、蛇腹16bが上下に位置して前後方向に伸び、封止縁部16bが両横方向に移動するように伸びて横長形態となるように膨らんでその奥側壁面が除塵子17の前面に当接する。そして、含塵空気は口紙16aの吸気窓16aから奥側壁面に向かって強く流れて奥側壁の内面に多く集塵され、塵は該部分に多く付着して該部分を目詰りさせる。 Incidentally, as shown in FIG. 14, when the paper bag type dust collecting filter 16 is installed in the dust collecting chamber 11 in such a posture that the filtering paper bag 16b swells in a horizontally long state, the collected filtering paper bag 16b is basically As shown in FIG. 15, the bellows 16b 2 is vertically positioned and extends in the front-rear direction, and the sealing edge portion 16b 3 expands so as to move in both lateral directions and swells into a horizontally long form. The rear side wall surface comes into contact with the front surface of the dust remover 17. Then, the dust-containing air is much dust collecting on the inner surface of the inner sidewall flowing strongly towards the rear side wall from the inlet window 16a 1 of the mouth paper 16a, the dust causes clogging the partial adhering more to the moiety.

このように集塵して膨らんだ濾過用紙袋16bの奥側壁面が除塵子17における格子状枠体17aの前面に接触した状態において、図16に示すように、除塵子17が繰り返し揺動して濾過用紙袋16bの奥側壁が振動すると該奥側壁の内面に付着している塵は震い落されて濾過用紙袋16bの下側に位置して伸びた蛇腹16bの部分に向かって落下する。しかして、この塵が落下して溜る蛇腹16bの位置は、吸引清掃時の強い気流の中心に比較的に近い位置となるので、震い落した塵が次の吸引清掃時の強い気流に巻き込まれて舞い上がって再び濾過用紙袋16bの奥側壁内面に付着するのを抑制(軽減)する効果が少なくなる。 In the state where the back side wall surface of the filter paper bag 16b which has been collected and inflated as described above is in contact with the front surface of the lattice frame 17a of the dust remover 17, the dust remover 17 repeatedly swings as shown in FIG. When the back side wall of the filter paper bag 16b vibrates, the dust adhering to the inner surface of the back side wall is shaken down and falls toward the bellows 16b 2 extending below the filter paper bag 16b. To do. Therefore, the position of the bellows 16b 2 where the dust falls and accumulates is relatively close to the center of the strong air flow at the time of suction cleaning, so that the shaken dust becomes a strong air current at the time of the next suction cleaning. The effect of suppressing (reducing) the winding up and rising again and adhering to the inner surface of the back side wall of the filter paper bag 16b is reduced.

この実施例1において使用した紙袋式集塵フィルタ16は、口紙16aを紙以外の部材で構成し、濾過用紙袋16bを紙以外の濾過材で構成して使用することが可能であり、このような集塵フィルタも含むものとする。   The paper bag type dust collecting filter 16 used in Example 1 can be used with the base paper 16a made of a member other than paper and the filter paper bag 16b made of a filter material other than paper. Such a dust collection filter is also included.
