It has been. The opening / closing operation of the second opening / closing valve 37 is controlled by the control means 8.

副集塵室22は、主集塵室21の分離部34に捕集された塵埃などを移動させて溜める補助的な集塵部で、内部に使い捨ての集塵袋としての紙パック38が着脱可能に収容されているとともに、この紙パック38の外部で吸込風路28との連通部である排気側に、紙パック38よりも目が細かい補助フィルタとしてのメッシュフィルタ39が配設されている。   The secondary dust collection chamber 22 is an auxiliary dust collection unit that moves and collects dust collected in the separation unit 34 of the main dust collection chamber 21, and a paper pack 38 as a disposable dust collection bag is attached and detached inside. A mesh filter 39 as an auxiliary filter that is finer than that of the paper pack 38 is disposed outside the paper pack 38 and on the exhaust side that is a communicating portion with the suction air passage 28 outside the paper pack 38. .

紙パック38は、連通路26,27の下端部に取り付けられた口板38a,38bと、これら口板38a,38bに一体的に設けられた袋状のフィルタ部38cとを有している。口板38a,38bには、図示しない開口がそれぞれ形成されて各連通路26,27とフィルタ部38c内とを連通するように構成されている。また、フィルタ部38cは、未使用状態で折り畳まれ、使用により副集塵室22内全体に膨らむように構成されている。   The paper pack 38 includes mouth plates 38a and 38b attached to lower ends of the communication passages 26 and 27, and a bag-like filter portion 38c provided integrally with the mouth plates 38a and 38b. Openings (not shown) are formed in the mouth plates 38a and 38b, respectively, so that the communication passages 26 and 27 communicate with the filter portion 38c. The filter unit 38c is configured to be folded when not in use and to swell throughout the sub-dust collection chamber 22 when used.

吸込風路28は、主集塵室21の下流側と副集塵室22の下流側とが合流して電動送風機5の吸込側と連通し、外気と連通し主集塵室21のメッシュフィルタ32の逆洗側へと外気を導入可能な外気導入孔51が穿設され、この外気導入孔51には、この外気導入孔51を開閉する外気切換弁としての外気進入弁52が配設され、この外気進入弁52は、制御手段8によりその開閉動作が制御される。   The suction air passage 28 is connected to the suction side of the electric blower 5 by the downstream side of the main dust collection chamber 21 and the downstream side of the sub dust collection chamber 22, and communicates with the outside air to mesh the main dust collection chamber 21. An outside air introduction hole 51 through which outside air can be introduced to the backwash side of 32 is formed, and an outside air entry valve 52 as an outside air switching valve for opening and closing the outside air introduction hole 51 is disposed in the outside air introduction hole 51. The open / close operation of the outside air entry valve 52 is controlled by the control means 8.

なお、以下、逆洗とは、フィルタにより塵埃などを捕集する際に流体が通過する方向と反対方向からこのフィルタに対して流体を通過させることで、このフィルタに付着した塵埃などを除去することをいう。   Hereinafter, backwashing removes dust adhering to the filter by allowing fluid to pass through the filter from a direction opposite to the direction in which the fluid passes when dust is collected by the filter. That means.

また、吸込風路28の下流端には、電動送風機5の吸込側を覆って第2フィルタとしての回転プリーツフィルタ54が回転可能に設けられている。この回転プリーツフィルタ54は、電動送風機5と略同軸上に配設され、メッシュフィルタ32よりも目が細かく形成され、メッシュフィルタ32を通過した細塵D2を捕集可能となっており、径方向に沿うプリーツ形状が周方向全体に亘って形成されている。また、この回転プリーツフィルタ54には、この回転プリーツフィルタ54に捕集した塵埃を、例えば振動などを与えることで除去する図示しない除塵装置が設けられている。この除塵装置は、制御手段8によりその動作が制御される。   A rotary pleat filter 54 as a second filter is rotatably provided at the downstream end of the suction air passage 28 so as to cover the suction side of the electric blower 5. The rotating pleated filter 54 is disposed substantially coaxially with the electric blower 5, has a finer mesh than the mesh filter 32, and is capable of collecting fine dust D 2 that has passed through the mesh filter 32. A pleated shape extending along the circumferential direction is formed over the entire circumferential direction. Further, the rotary pleat filter 54 is provided with a dust removal device (not shown) that removes dust collected by the rotary pleat filter 54 by applying vibration or the like. The operation of the dust removing device is controlled by the control means 8.

さらに、吸込風路28の上流端には、切換弁55が設けられている。この切換弁55は、主集塵室21と副集塵室22とのいずれか一方を選択的に、吸込風路28を介して電動送風機5の吸込側に連通させるものであり、制御手段8によりその開閉動作が制御される。   Further, a switching valve 55 is provided at the upstream end of the suction air passage 28. The switching valve 55 selectively connects one of the main dust collection chamber 21 and the sub dust collection chamber 22 to the suction side of the electric blower 5 via the suction air passage 28. The opening / closing operation is controlled by.

一方、洗浄風路29は、副集塵室22のメッシュフィルタ39の下流側と電動送風機5の吸込側とを、吸込風路28と別個に接続するもので、第3フィルタとしての固定プリーツフィルタ56を副集塵室22の下流側との連通部に備え、制御手段8により動作が制御される細塵フィルタ弁57の移動により吸込風路28と洗浄風路29とのいずれか一方が選択的に電動送風機5の吸込側に連通するように構成されている。   On the other hand, the cleaning air passage 29 connects the downstream side of the mesh filter 39 in the sub dust collection chamber 22 and the suction side of the electric blower 5 separately from the suction air passage 28, and is a fixed pleated filter as a third filter. 56 is provided at the communicating portion with the downstream side of the sub dust collection chamber 22, and either the suction air passage 28 or the washing air passage 29 is selected by the movement of the fine dust filter valve 57 whose operation is controlled by the control means 8. Thus, the electric blower 5 is configured to communicate with the suction side.

固定プリーツフィルタ56は、メッシュフィルタ39よりも目が細かく形成され、メッシュフィルタ39を通過した細塵を捕集可能となっており、例えばプリーツ形状が前後方向に沿うように、前側から後側へと上側に傾斜するように配設されている。   The fixed pleat filter 56 has a finer mesh than the mesh filter 39 and can collect fine dust that has passed through the mesh filter 39. For example, from the front side to the rear side so that the pleat shape is along the front-rear direction. And are arranged so as to incline upward.

In the first state in which the negative pressure of the blower 5 forms the main air passage W1 that acts on the floor brush 17, the extension pipe 16, the hose body 12, the main body suction port 11, the separation portion 34, the communication portion 35, and the suction air passage 28. In a certain cleaning state, the negative pressure of the electric blower 5 acts on the outside air introduction hole 51, the suction air passage 28, the communication portion 35, the second communication passage 27, the sub dust collection chamber 22, and the cleaning air passage 29. The fine dust moving state which is the second state forming the path W2, and the negative pressure of the electric blower 5 are the outside air introduction hole 51, the suction air path 28, the communication part 35, the separation part 34, the first communication path 26, the sub-collection. The coarse dust moving state, which is the third state that forms the second auxiliary air passage W3 acting with the dust chamber 22 and the cleaning air passage 29, and the negative pressure of the electric blower 5 are the floor brush 17, the extension pipe 16, the ho A filter cleaning state that is a fourth state that forms a third sub air passage W4 that acts on the body 12, the main body suction port 11, the separation portion 34, the first communication passage 26, the sub dust collection chamber 22, and the suction air passage 28. , Can be selectively switched.

次に、上記一実施の形態の動作を説明する。   Next, the operation of the above embodiment will be described.

まず、本体吸込口11にホース体12、延長管16および床ブラシ17を順次連通接続するとともに、本体ケース4の蓋体3を開けて集塵ユニット7を装着し、蓋体3を閉じる。   First, the hose body 12, the extension pipe 16 and the floor brush 17 are sequentially connected to the main body suction port 11, the lid body 3 of the main body case 4 is opened, the dust collecting unit 7 is attached, and the lid body 3 is closed.

そして、本体ケース4から電源コードを引き出して壁面などのコンセントに接続し、作業者が把持部14を把持して所定の設定ボタン15を操作すると、制御手段8が除塵装置を駆動させて回転プリーツフィルタ54に捕集した微細な塵埃である細塵D2をこの回転プリーツフィルタ54から叩き落した後、電動送風機5を駆動させる。   Then, the power cord is pulled out from the main body case 4 and connected to an outlet such as a wall surface. When the operator grips the grip 14 and operates a predetermined setting button 15, the control means 8 drives the dust remover to rotate the pleat. After the fine dust D2, which is fine dust collected by the filter 54, is knocked down from the rotary pleat filter 54, the electric blower 5 is driven.

このとき、制御手段8は、図2に示すように、切換弁55により主集塵室22側を閉塞するとともに細塵フィルタ弁57により吸込風路28を閉塞して、洗浄風路29を介して副集塵室22の下流側を電動送風機5の吸込側に連通させ、第2開閉弁37を開いて第1開閉弁36を閉じ、主集塵室21の連通部35と副集塵室22とを連通させ、連通管弁31を閉じて主集塵室21の上流側を閉塞し、かつ、外気進入弁52を開く(細塵移動状態)。   At this time, as shown in FIG. 2, the control means 8 closes the main dust collection chamber 22 side by the switching valve 55 and closes the suction air passage 28 by the fine dust filter valve 57, and passes the cleaning air passage 29. The downstream side of the sub dust collection chamber 22 is communicated with the suction side of the electric blower 5, the second on-off valve 37 is opened and the first on-off valve 36 is closed, and the communication portion 35 of the main dust collection chamber 21 and the sub dust collection chamber are opened. 22, the communication pipe valve 31 is closed, the upstream side of the main dust collecting chamber 21 is closed, and the outside air entry valve 52 is opened (fine dust movement state).

このため、電動送風機5の駆動により、負圧が外気導入孔51、吸込風路28、連通部35、第2連通路27、副集塵室22および洗浄風路29と作用する第1副風路W2が形成され、外気が外気導入孔51から導入され、連通部35から第2連通路27を介して副集塵室22へと流入し、紙パック38およびメッシュフィルタ39を通過した後、固定プリーツフィルタ56を通過して洗浄風路29へと流入し、電動送風機5に吸い込まれ、電動送風機5を通過して排気風となり、図示しない排気孔から掃除機本体1の外部へと排気される。   Therefore, the first auxiliary wind in which negative pressure acts on the outside air introduction hole 51, the suction air passage 28, the communication portion 35, the second communication passage 27, the sub dust collection chamber 22 and the cleaning air passage 29 by driving the electric blower 5. After the passage W2 is formed, outside air is introduced from the outside air introduction hole 51, flows into the sub dust collection chamber 22 from the communication portion 35 through the second communication passage 27, and passes through the paper pack 38 and the mesh filter 39. It passes through the fixed pleat filter 56 and flows into the cleaning air passage 29, is sucked into the electric blower 5, passes through the electric blower 5, becomes exhaust air, and is exhausted from the exhaust hole (not shown) to the outside of the cleaner body 1. The

ここで、外気導入孔51から取り込まれた外気が、回転プリーツフィルタ54から叩き落された塵埃を、連通部35および第2連通路27を介して副集塵室22の紙パック38へと移動させ、この紙パック38に一部を捕集するとともに、この紙パック38を通過した細塵D2の残りは、空気がメッシュフィルタ39および固定プリーツフィルタ56を通過する際に、これらメッシュフィルタ39および固定プリーツフィルタ56により捕集する。   Here, the outside air taken in from the outside air introduction hole 51 moves the dust blown off from the rotary pleat filter 54 to the paper pack 38 of the sub dust collection chamber 22 through the communication portion 35 and the second communication passage 27. A part of the fine dust D2 that has passed through the paper pack 38 is collected when the air passes through the mesh filter 39 and the fixed pleated filter 56, and a part of the dust is collected in the paper pack 38. Collected by fixed pleated filter 56.

この結果、回転プリーツフィルタ56が洗浄される。   As a result, the rotary pleat filter 56 is cleaned.

この後、制御手段8は、図1に示すように、切換弁55により副集塵室22側を閉塞するとともに細塵フィルタ弁57により洗浄風路29を閉塞し、吸込風路28を介して主集塵室21の下流側を電動送風機5の吸込側に連通させ、各開閉弁36,37を閉じて主集塵室21の分離部34および連通部35と副集塵室22との連通を遮断し、連通管弁31を開いて主集塵室21の上流側を開放し、かつ、外気進入弁52を閉じて主集塵室21への外気を遮断する(掃除状態)。   Thereafter, as shown in FIG. 1, the control means 8 closes the sub dust collection chamber 22 side by the switching valve 55 and closes the cleaning air passage 29 by the fine dust filter valve 57, and passes through the suction air passage 28. The downstream side of the main dust collection chamber 21 is communicated with the suction side of the electric blower 5, the on-off valves 36 and 37 are closed, and the separation portion 34 and the communication portion 35 of the main dust collection chamber 21 communicate with the sub dust collection chamber 22. The communication pipe valve 31 is opened to open the upstream side of the main dust collection chamber 21, and the outside air entry valve 52 is closed to shut off the outside air to the main dust collection chamber 21 (cleaning state).

この結果、電動送風機5の駆動により、負圧が床ブラシ17、延長管16、ホース体12、本体吸込口11、分離部34、連通部35および吸込風路28と作用する主風路W1が形成され、空気とともに塵埃が主集塵室21へと吸い込まれる。   As a result, when the electric blower 5 is driven, a main air passage W1 in which negative pressure acts on the floor brush 17, the extension pipe 16, the hose body 12, the main body suction port 11, the separation portion 34, the communication portion 35, and the suction air passage 28 is obtained. The dust is formed and sucked into the main dust collecting chamber 21 together with the air.

そして、この主集塵室21へと吸い込まれた塵埃のうち、比較的大きい塵埃である粗塵D1は例えば遠心分離されて分離部34内に捕集され、細塵の一部は空気がメッシュフィルタ32を通過する際に、このメッシュフィルタ32により捕集され、さらに、このメッシュフィルタ32を通過した細塵D2は、回転プリーツフィルタ54を空気が通過する際に、この回転プリーツフィルタ54に捕集される。なお、分離部34内に収容された粗塵D1は、通過する空気により圧縮される。   Of the dust sucked into the main dust collection chamber 21, coarse dust D1, which is relatively large dust, is centrifuged, for example, and collected in the separation unit 34, and air is meshed in some fine dust. The fine dust D2 collected by the mesh filter 32 when passing through the filter 32 and further passing through the mesh filter 32 is captured by the rotary pleat filter 54 when air passes through the rotary pleat filter 54. Be collected. Note that the coarse dust D1 accommodated in the separation part 34 is compressed by the passing air.

回転プリーツフィルタ54を通過した空気は、吸込風路28を介して電動送風機5へと吸い込まれ、電動送風機5を通過して排気風となり、図示しない排気孔から掃除機本体1の外部へと排気される。   The air that has passed through the rotary pleat filter 54 is sucked into the electric blower 5 through the suction air passage 28, passes through the electric blower 5 to become exhaust air, and is exhausted from the exhaust hole (not shown) to the outside of the cleaner body 1. Is done.

次いで、掃除を終了する際に、作業者が設定ボタン15を操作すると、制御手段8は、除塵装置を駆動させて、図2に示す上記細塵移動状態を選択し、回転プリーツフィルタ54に捕集された細塵D2を副集塵室22の紙パック38へと移動させてこの紙パック38、メッシュフィルタ39および固定プリーツフィルタ56に捕集する。   Next, when the operator operates the setting button 15 when cleaning is completed, the control means 8 drives the dust removing device to select the fine dust moving state shown in FIG. The collected fine dust D2 is moved to the paper pack 38 in the sub-dust collection chamber 22 and collected in the paper pack 38, the mesh filter 39, and the fixed pleat filter 56.

また、制御手段8は、図3に示すように、切換弁55により副集塵室22側を閉塞するとともに細塵フィルタ弁57により吸込風路28を閉塞して、洗浄風路29を介して副集塵室22の下流側を電動送風機5の吸込側に連通させた状態で、第1開閉弁36を開いて第2開閉弁37を閉じ、主集塵室21の分離部34と副集塵室22とを連通させ、連通管弁31を閉じて主集塵室21の上流側を閉塞し、かつ、外気進入弁52を開く(粗塵移動状態)。   Further, as shown in FIG. 3, the control means 8 closes the sub dust collection chamber 22 side by the switching valve 55 and closes the suction air passage 28 by the fine dust filter valve 57, and passes through the cleaning air passage 29. In a state where the downstream side of the sub dust collection chamber 22 is in communication with the suction side of the electric blower 5, the first on / off valve 36 is opened and the second on / off valve 37 is closed, and the separation unit 34 of the main dust collection chamber 21 and the sub collection The dust chamber 22 is communicated, the communication pipe valve 31 is closed, the upstream side of the main dust collection chamber 21 is closed, and the outside air entry valve 52 is opened (coarse dust movement state).

このとき、分離部34に捕集された粗塵D1の一部が、自重により第1連通路26を介して副集塵室22へと落下し、紙パック38に捕集される。   At this time, a part of the coarse dust D1 collected by the separation unit 34 falls to the sub dust collection chamber 22 through the first communication path 26 by its own weight, and is collected by the paper pack 38.

さらに、電動送風機5の駆動により、負圧が外気導入孔51、吸込風路28、連通部35、分離部34、第1連通路26、副集塵室22および洗浄風路29と作用する第2副風路W3が形成され、外気が外気導入孔51から主集塵室21へと導入される。   Further, when the electric blower 5 is driven, negative pressure acts on the outside air introduction hole 51, the suction air passage 28, the communication portion 35, the separation portion 34, the first communication passage 26, the sub dust collection chamber 22 and the cleaning air passage 29. Two auxiliary air passages W3 are formed, and the outside air is introduced from the outside air introduction hole 51 into the main dust collecting chamber 21.

そして、この外気は、メッシュフィルタ32を下流側から上流側へと通過してこのメッシュフィルタ32を逆洗し、第1連通路26を介して副集塵室22へと吸い込まれ、紙パック38、メッシュフィルタ39および固定プリーツフィルタ56を順次通過し、洗浄風路29を通過して電動送風機5へと吸い込まれ、電動送風機5を通過して排気風となり、図示しない排気孔から掃除機本体1の外部へと排気される。   The outside air passes through the mesh filter 32 from the downstream side to the upstream side, backwashes the mesh filter 32, and is sucked into the sub-dust collection chamber 22 through the first communication path 26, and the paper pack 38 , Sequentially passing through the mesh filter 39 and the fixed pleated filter 56, passing through the cleaning air passage 29 and sucked into the electric blower 5, passing through the electric blower 5 to become exhaust air, and from the exhaust hole (not shown) to the vacuum cleaner main body 1 Exhausted to the outside.

この結果、分離部34に捕集された粗塵D1の残りが、外気の流れにより第1連通路26から副集塵室22の紙パック38へと流入し、この紙パック38、あるいはメッシュフィルタ39に捕集される。   As a result, the remaining coarse dust D1 collected in the separation unit 34 flows into the paper pack 38 of the sub-dust collection chamber 22 from the first communication path 26 due to the flow of outside air, and the paper pack 38 or the mesh filter. Collected by 39.

さらに、制御手段8は、図4に示すように、切換弁55により主集塵室21側を閉塞するとともに細塵フィルタ弁57により洗浄風路29を閉塞して、吸込風路28を介して副集塵室22の下流側を電動送風機5の吸込側に連通させた状態で、第1開閉弁36を開いて第2開閉弁37を閉じ、主集塵室21の分離部34と副集塵室22とを連通させ、連通管弁31を開いて主集塵室21の上流側を開放し、かつ、外気進入弁52を閉じて主集塵室21への外気を遮断する(フィルタ洗浄状態)。   Further, as shown in FIG. 4, the control means 8 closes the main dust collecting chamber 21 side by the switching valve 55 and closes the cleaning air passage 29 by the fine dust filter valve 57, and passes through the suction air passage 28. In a state where the downstream side of the sub dust collection chamber 22 is in communication with the suction side of the electric blower 5, the first on / off valve 36 is opened and the second on / off valve 37 is closed, and the separation unit 34 of the main dust collection chamber 21 and the sub collection The dust chamber 22 is communicated, the communication pipe valve 31 is opened to open the upstream side of the main dust collection chamber 21, and the outside air entry valve 52 is closed to shut off the outside air to the main dust collection chamber 21 (filter cleaning). Status).

このとき、分離部34に捕集された粗塵D1の一部が、自重により第1連通路26を介して副集塵室22へと落下し、紙パック38に捕集される。   At this time, a part of the coarse dust D1 collected by the separation unit 34 falls to the sub dust collection chamber 22 through the first communication path 26 by its own weight, and is collected by the paper pack 38.

同時に、電動送風機5の駆動により、負圧が床ブラシ17、延長管16、ホース体12、本体吸込口11、分離部34、第1連通路26、副集塵室22および吸込風路28と作用する第3副風路W4が形成され、空気が主集塵室21へと吸い込まれる。   At the same time, when the electric blower 5 is driven, negative pressure is generated from the floor brush 17, the extension pipe 16, the hose body 12, the main body suction port 11, the separation portion 34, the first communication passage 26, the sub dust collection chamber 22, and the suction air passage 28. The acting third auxiliary air passage W4 is formed, and air is sucked into the main dust collecting chamber 21.

そして、この吸い込まれた空気は、第1連通路26を介して副集塵室22へと吸い込まれ、紙パック38およびメッシュフィルタ39を通過し、さらに、固定プリーツフィルタ56の塵埃捕集面である上面を通過し、この固定プリーツフィルタ56を洗浄して、この固定プリーツフィルタ56にて捕集した細塵を除去する。   Then, the sucked air is sucked into the sub dust collection chamber 22 through the first communication passage 26, passes through the paper pack 38 and the mesh filter 39, and further, on the dust collecting surface of the fixed pleat filter 56. The fixed pleated filter 56 is washed by passing through a certain upper surface, and fine dust collected by the fixed pleated filter 56 is removed.

この後、この除去された細塵は、空気が吸込風路28を経由して回転プリーツフィルタ54を通過する際に、この回転プリーツフィルタ54に捕集される。   Thereafter, the removed fine dust is collected by the rotary pleat filter 54 when the air passes through the rotary pleat filter 54 via the suction air passage 28.

この結果、固定プリーツフィルタ56が洗浄される。   As a result, the fixed pleated filter 56 is cleaned.

また、回転プリーツフィルタ54を通過した空気は、電動送風機5へと吸い込まれ、電動送風機5を通過して排気風となり、図示しない排気孔から掃除機本体1の外部へと排気される。   The air that has passed through the rotary pleat filter 54 is sucked into the electric blower 5, passes through the electric blower 5, becomes exhaust air, and is exhausted from the exhaust hole (not shown) to the outside of the cleaner body 1.

そして、制御手段8は、所定時間が経過すると、電動送風機5を停止させて、電気掃除機の運転を停止する。   And the control means 8 will stop the electric blower 5 and stop the operation | movement of a vacuum cleaner, if predetermined time passes.

紙パック38に所定量以上の塵埃が溜まった場合には、蓋体3を開けて紙パック38を副集塵室22から取り外して塵埃とともに廃棄し、新たな紙パック38を副集塵室22に装着する。   When a predetermined amount or more of dust has accumulated in the paper pack 38, the lid 3 is opened, the paper pack 38 is removed from the sub dust collection chamber 22 and discarded together with the dust, and a new paper pack 38 is disposed in the sub dust collection chamber 22. Attach to.

上述したように、上記一実施の形態では、上記掃除状態を切換機構58により選択することで、主集塵室21の分離部34に粗塵D1を捕集し、メッシュフィルタ32および回転プリーツフィルタ54に細塵D2を捕集し、上記細塵移動状態を切換機構58により選択することで、回転プリーツフィルタ54に捕集した細塵D2を副集塵室22へ移動させて回転プリーツフィルタ54を洗浄し、上記粗塵移動状態を切換機構58により選択することで、メッシュフィルタ32を洗浄するとともに主集塵室21に捕集した粗塵D1を副集塵室22へと移動させ、かつ、上記フィルタ洗浄状態を切換機構58により選択することで、固定プリーツフィルタ56を洗浄する構成とした。   As described above, in the above embodiment, by selecting the cleaning state by the switching mechanism 58, the coarse dust D1 is collected in the separation part 34 of the main dust collecting chamber 21, and the mesh filter 32 and the rotary pleat filter are collected. The fine dust D2 is collected in 54, and the fine dust moving state is selected by the switching mechanism 58, so that the fine dust D2 collected in the rotary pleat filter 54 is moved to the sub-dust collection chamber 22, and the rotary pleat filter 54 By selecting the coarse dust movement state by the switching mechanism 58, the mesh filter 32 is washed and the coarse dust D1 collected in the main dust collection chamber 21 is moved to the sub dust collection chamber 22, and The fixed pleat filter 56 is cleaned by selecting the filter cleaning state with the switching mechanism 58.

この結果、主集塵室21および各フィルタ32,54,56が清浄な状態に保たれ、掃除の際にメインで使用する主集塵室21側に粗塵D1および細塵D2が溜まり続けたり、メッシュフィルタ32および各プリーツフィルタ54,56が経時的に目詰まりしたりすることが抑制されるので、主集塵室21から移動させた粗塵D1および細塵D2が紙パック38いっぱいに溜まるまで、経時的な吸込力の低下を抑制できる。   As a result, the main dust collection chamber 21 and the filters 32, 54, and 56 are kept clean, and coarse dust D1 and fine dust D2 continue to accumulate on the main dust collection chamber 21 side that is mainly used for cleaning. Since the mesh filter 32 and the pleat filters 54 and 56 are prevented from clogging over time, the coarse dust D1 and fine dust D2 moved from the main dust collecting chamber 21 are accumulated in the paper pack 38. Until then, it is possible to suppress a decrease in suction force over time.

また、主集塵室21にて一旦圧縮した粗塵D1を副集塵室22の紙パック38へと移動させるので、紙パック38へ移動させる粗塵D1の嵩が低減し、紙パック38の容量を、より有効に利用できる。   Further, since the coarse dust D1 once compressed in the main dust collection chamber 21 is moved to the paper pack 38 in the sub dust collection chamber 22, the bulk of the coarse dust D1 moved to the paper pack 38 is reduced, and the paper pack 38 Capacity can be used more effectively.

さらに、主集塵室21を副集塵室22の上方に配設することにより、切換機構58により第1開閉弁36を開いた際に第1連通路26を介して、分離部34に捕集した粗塵D1の一部を副集塵室22へと自重により落下させることが可能になるとともに、細塵D2および粗塵D1を外気により副集塵室22へと移動させる際にも、これら細塵D2および粗塵D1を効率よく移動させることができる。   Further, by disposing the main dust collecting chamber 21 above the sub dust collecting chamber 22, when the first opening / closing valve 36 is opened by the switching mechanism 58, the main dust collecting chamber 21 is captured by the separation unit 34 via the first communication passage 26. Part of the collected coarse dust D1 can be dropped into the sub dust collection chamber 22 by its own weight, and when moving the fine dust D2 and coarse dust D1 to the sub dust collection chamber 22 by the outside air, These fine dust D2 and coarse dust D1 can be moved efficiently.

なお、上記一実施の形態において、主集塵室21と副集塵室22とは、主集塵室21を上側、副集塵室22を下側とする以外でも、他の様々な配置が可能である。   In the above embodiment, the main dust collection chamber 21 and the sub dust collection chamber 22 have various other arrangements other than the main dust collection chamber 21 being the upper side and the sub dust collection chamber 22 being the lower side. Is possible.

また、各弁31,36,37,55,52,57の開閉動作は、制御手段8にて制御したが、制御する別個の弁制御手段を設けたり、いずれかの弁の開閉に機械的に連動させて他の各弁を開閉させたりしてもよい。   Further, the opening / closing operation of each valve 31, 36, 37, 55, 52, 57 is controlled by the control means 8. However, a separate valve control means for controlling is provided, or mechanical opening / closing of any one of the valves is mechanically performed. Other valves may be opened and closed in conjunction with each other.

さらに、紙パック38に代えて、ティッシュペーパなどの二次フィルタを副集塵室22に取り付けることも可能であり、また、二次フィルタを副集塵室22に取り付けずに、副集塵室22自体を掃除機本体1に対して着脱可能な集塵カップのように構成することも可能である。   Furthermore, instead of the paper pack 38, a secondary filter such as tissue paper can be attached to the sub dust collection chamber 22, and the secondary filter is not attached to the sub dust collection chamber 22, and the sub dust collection chamber 22 is not attached. It is also possible to configure 22 itself as a dust collection cup that can be attached to and detached from the cleaner body 1.

そして、メッシュフィルタ39を設けない構成とすることも可能である。   A configuration in which the mesh filter 39 is not provided is also possible.

また、電気掃除機の細部は、上記構成に限定されるものではなく、電気掃除機としては、キャニスタ型に限らず、例えば自走式(走行補助式)や自律走行式(ロボット式)の電気掃除機などでもよく、また、例えば床ブラシ17が掃除機本体1の下面に直接形成されたアップライト型、あるいはハンディ型などであっても対応させて用いることができる。   The details of the vacuum cleaner are not limited to the above configuration, and the vacuum cleaner is not limited to the canister type, for example, self-propelled (running assist type) or autonomous running type (robot type) electric For example, a vacuum cleaner or the like may be used. For example, the floor brush 17 may be an upright type or a handy type directly formed on the lower surface of the vacuum cleaner body 1.
