Description

この発明は、駆動モータにより回転駆動される回転清掃体が設けられた電気掃除機用吸込口体に関するものである。   The present invention relates to a suction port for a vacuum cleaner provided with a rotary cleaning body that is rotationally driven by a drive motor.

従来の電気掃除機の吸込口体としては、吸込口本体内に左右に延びる吸込室を設け、この吸込室の吸込開口を吸込口本体の底面に開口させ、この吸込開口に沿って吸込室に配設した回転清掃体の左右両端部を吸込口本体に回転自在に取り付けると共に、この回転清掃体を回転駆動する駆動モータを設けた構成のものが知られている。   As a suction port body of a conventional vacuum cleaner, a suction chamber extending left and right is provided in the suction port body, and the suction opening of this suction chamber is opened at the bottom surface of the suction port body, and the suction chamber is formed along the suction opening. A configuration is known in which left and right end portions of a rotary cleaning body arranged are rotatably attached to a suction port body, and a drive motor for rotating the rotary cleaning body is provided.

このような吸込口体は、吸込口本体に回転自在に取り付けられ且つ駆動モータに連動する回転軸と、回転軸に沿って螺旋状に取り付けられた可撓性ブレードや毛ブラシ等の塵埃掻き上げ部材と、を備えているのが普通である（例えば、特許文献１参照）。   Such a suction port body is rotatably attached to the suction port body and is linked to a drive motor, and a dust blade such as a flexible blade or a hair brush attached spirally along the rotation shaft. It is common to have a member (see, for example, Patent Document 1).

このような吸込口体としては、清掃面の塵埃を掻き上げる回転清掃体の回転が吸込口体の前進方向に推進力を与えるように、回転清掃体を駆動モータで正回転方向に回転駆動するようになっているものも知られている。
特開２００４−１４７６９１号公報 As such a suction port body, the rotary cleaning body is driven to rotate in the forward rotation direction by a drive motor so that the rotation of the rotary cleaning body that sweeps up dust on the cleaning surface gives a propulsive force in the forward direction of the suction port body. Some are also known.
JP 2004-147691 A

このような吸込口体では、回転清掃体に糸くずや髪の毛等の塵埃が巻き付いたり、毛ブラシの場合には糸くずや髪の毛等とこれ以外の細かい塵埃も付着したまま残ってしまうこともある。この場合には、回転清掃体による塵埃の掻き上げ効率が低下するために、回転清掃体に付着した塵埃を取り除く必要がある。   In such a suction port body, dust such as lint and hair may wrap around the rotary cleaning body, or in the case of a bristle brush, lint, hair, etc. and other fine dust may remain attached. . In this case, it is necessary to remove the dust adhering to the rotary cleaning body because the efficiency of scraping dust by the rotary cleaning body is reduced.

しかしながら、この塵埃を回転清掃体から除去するには回転清掃体を吸込口本体から取り外す必要があり、塵埃の除去に手間がかかるものであった。   However, in order to remove the dust from the rotary cleaning body, it is necessary to remove the rotary cleaning body from the suction port body, and it takes time to remove the dust.

そこで、この発明は、手間がかからず塵埃を回転清掃体から容易に除去できる電気掃除機用吸込口体を提供することを目的とするものである。   Therefore, an object of the present invention is to provide a suction port body for a vacuum cleaner that can be easily removed from a rotary cleaning body without taking time and effort.

この目的を達成するため、この発明は、吸込室が設けられ且つ前記吸込室の吸込開口が底面に開口する吸込口本体と、前記吸込開口に沿って配設された回転清掃体と、前記回転清掃体を回転駆動する駆動モータを備え、前記回転清掃体は、前記吸込口本体に回転自在に取り付けられ且つ前記駆動モータに連動する回転軸と、前記回転軸に沿って半径方向に突出するように取り付けられた塵埃掻き上げ部材を有する電気掃除機用吸込口体において、前記回転清掃体を逆回転させたときに前記塵埃掻き上げ部材に付着する塵埃を掻落可能な塵埃掻落部材が前記吸込室の上壁に設けられていると共に、前記回転清掃体を前進方向とは反対方向に逆回転させる操作手段が設けられている電気掃除機用吸込口体としたことを特徴とする。   In order to achieve this object, the present invention includes a suction port body provided with a suction chamber and a suction opening of the suction chamber opened on a bottom surface, a rotary cleaning body disposed along the suction opening, and the rotation A drive motor for rotationally driving the cleaning body, wherein the rotary cleaning body is rotatably attached to the suction port body and is coupled to the drive motor, and protrudes in a radial direction along the rotation axis; In the suction port body for a vacuum cleaner having a dust cleaning member attached to the suction chamber, the dust cleaning member capable of scraping dust adhering to the dust cleaning member when the rotary cleaning body is rotated in the reverse direction is the suction chamber. And a suction port for a vacuum cleaner provided with an operating means for rotating the rotary cleaning body in the direction opposite to the forward direction.

この構成によれば、操作手段を操作して回転清掃体を逆回転させることにより、前記塵埃掻き上げ部材が塵埃掻落部材に接触して、前記塵埃掻き上げ部材に付着した塵埃を塵埃掻落部材により掻き落とすことができるので、手間がかからず塵埃を回転清掃体から容易に除去できる。   According to this configuration, by operating the operating means to reversely rotate the rotary cleaning body, the dust scraping member contacts the dust scraping member, and the dust adhering to the dust scraping member is removed by the dust scraping member. Since it can be scraped off, it is possible to remove dust from the rotary cleaning body without much trouble.

It has the timing belt 23 passed.

更に、前上ケース１４には図１，図２，図２Ａに示したように、回転清掃体１８のブラシ毛帯１８ｂを設けた部分に沿って左右に延びる開口２４が形成されている。この前上ケース１４には、開口２４内に配設した塵埃掻落蓋（塵埃掻落部材）２５の後縁両側部が左右に延びる支持軸２６を中心に回動可能に取り付けられている。   Further, as shown in FIGS. 1, 2, and 2 </ b> A, the front upper case 14 is formed with an opening 24 that extends to the left and right along a portion where the brush band 18 b of the rotary cleaning body 18 is provided. On the front upper case 14, both sides of the rear edge of a dust scraping lid (dust scraping member) 25 disposed in the opening 24 are attached so as to be rotatable about a support shaft 26 extending in the left-right direction.

また、前上ケース１４の内面には図４，図５に示したように支持突部１４ａが設けられ、支持突部１４ａにはソレノイド２７が取り付けられている。このソレノイド２７は、塵埃掻落部蓋２５を回転清掃体１８側に僅かに開閉回動させるようになっている。そして、図５の如く塵埃掻落部蓋２５がソレノイド２７で回転清掃体１８側に開かれたときに、塵埃掻落部蓋２５の先端がブラシ毛帯１８ｂに当たる位置まで移動すると共に、塵埃掻落部蓋２５の先端と開口２４の前縁との間に左右にスリット状に延びる空気導入口２８が形成されるようになっている（図２Ａ参照）。尚、後上ケース１３にはメンテナンス用スイッチ２９が設けられている。また、塵埃掻落部蓋２５は図示を省略したネジリコイルバネで開口２４を閉成する方向に回動付勢されている。このネジリコイルバネは支持軸２６に捲回した状態で塵埃掻落部蓋２５と前上ケース１４との間に介装することができる。   Further, as shown in FIGS. 4 and 5, a support protrusion 14a is provided on the inner surface of the front upper case 14, and a solenoid 27 is attached to the support protrusion 14a. The solenoid 27 is configured to slightly open and close the dust scraping portion cover 25 toward the rotary cleaning body 18. Then, as shown in FIG. 5, when the dust scraping portion lid 25 is opened to the rotary cleaning body 18 side by the solenoid 27, the tip of the dust scraping portion lid 25 moves to a position where it contacts the brush hair band 18b, and the dust scraping portion lid Between the front end of 25 and the front edge of the opening 24, an air inlet 28 extending in a slit shape on the left and right is formed (see FIG. 2A). The rear upper case 13 is provided with a maintenance switch 29. Further, the dust scraping portion lid 25 is urged to rotate in a direction to close the opening 24 by a torsion coil spring (not shown).

また、操作パネル８ａからの操作信号は、図６に示した演算制御回路（制御手段）３０に入力されるようになっている。この演算制御回路３０は、操作パネル８ａからの操作信号を受けて電動送風機５及び駆動モータ２１を回転制御するようになっている。尚、演算制御回路３０は、通常の操作パネル８ａからの操作信号を受けたとき、回転清掃体１８が吸込口体１０の前進方向に回転するように、駆動モータ２１を回転制御させるようになっている。   Further, an operation signal from the operation panel 8a is input to the arithmetic control circuit (control means) 30 shown in FIG. The arithmetic control circuit 30 receives the operation signal from the operation panel 8a and controls the rotation of the electric blower 5 and the drive motor 21. The arithmetic control circuit 30 controls the rotation of the drive motor 21 so that the rotary cleaning body 18 rotates in the forward direction of the suction port body 10 when receiving an operation signal from the normal operation panel 8a. ing.

更に、演算制御回路３０は、メンテナンス用スイッチ２９からのＯＮ信号を受けると、駆動モータ２１を逆転させると共に、ソレノイド２７を作動させて、塵埃掻落部蓋２５をこれの先端にブラシ毛帯１８ｂが当たるまでソレノイド２７により回転清掃体１８側に回動させるようになっている。   Further, upon receiving an ON signal from the maintenance switch 29, the arithmetic control circuit 30 reverses the drive motor 21 and operates the solenoid 27 so that the dust scraper lid 25 has the brush bristle band 18b at the tip thereof. The solenoid 27 is rotated by the solenoid 27 until it hits.

次に、このような構成の電気掃除機の作用を説明する。
（１）通常の清掃面Ｓの清掃
手元操作パイプ８に設けた「弱／中」吸込風量切り替え用のスイッチＳ１又は「強」吸込風量用のスイッチＳ２をオン操作すると、演算制御回路３０が電動送風機５を作動させ、電動送風機５の吸込負圧を集塵室３に作用させる。 Next, the operation of the vacuum cleaner having such a configuration will be described.
(1) Cleaning of normal cleaning surface S When the switch S1 for switching the “weak / medium” suction air volume provided on the hand operation pipe 8 or the switch S2 for the “strong” suction air volume is turned on, the arithmetic control circuit 30 is electrically operated. The blower 5 is operated, and the suction negative pressure of the electric blower 5 is applied to the dust collection chamber 3.

この集塵室３に作用する吸込負圧は、図１の状態で紙パックフィルタ４，集塵ホース７，手元操作パイプ８，延長管９，接続パイプ１７を介して吸込口本体１０ａの吸込室１５に作用する。   The suction negative pressure acting on the dust collection chamber 3 is the suction chamber of the suction port body 10a through the paper pack filter 4, the dust collection hose 7, the hand operation pipe 8, the extension pipe 9, and the connection pipe 17 in the state shown in FIG. Acts on 15.

一方、演算制御回路３０は、スイッチＳ１，Ｓ２のＯＮ操作により駆動モータ２１を作動制御して、駆動モータ２１の回転を動力伝達手段２２のタイミングプーリ２１ｂ，１８ｅ及びタイミングベルト２３を介してメイン回転清掃体１８に伝達させ、メイン回転清掃体１８を図４の矢印Ａ１で示したように時計回り方向（吸込口体１０に前進方向への回転力を与える回転方向）に回転させる。   On the other hand, the arithmetic control circuit 30 controls the operation of the drive motor 21 by turning on the switches S1 and S2, and rotates the drive motor 21 through the timing pulleys 21b and 18e of the power transmission means 22 and the timing belt 23. The main rotating cleaning body 18 is rotated in the clockwise direction (rotating direction that applies a rotational force in the forward direction to the suction port body 10) as indicated by an arrow A1 in FIG.

これにより、メイン回転清掃体１８は、回転しながらブラシ毛帯１８ｂの一部を吸込開口１５ａから下方に突出して、ブラシ毛帯１８ｂにより清掃面Ｓの塵埃を後方に掻き上げさせる。   Thereby, the main rotary cleaning body 18 projects a part of the brush bristle band 18b downward from the suction opening 15a while rotating, and causes the brush bristle band 18b to scrape dust on the cleaning surface S backward.

そして、吸込室１５に作用する吸込負圧は、清掃面Ｓの塵埃の一部を直接空気（エア）と共に吸込室１５内に吸い込む一方、メイン回転清掃体１８で掻き上げられた清掃面Ｓの塵埃を空気と共に吸込室１５内に吸い込むことになる。
そして、吸込室１５内に吸い込まれた塵埃を含む空気は、接続パイプ１７，延長管９，手元操作パイプ８及び集塵ホース７を介して紙パックフィルタ４内に吸い込まれて、紙パックフィルタ４を透過する。 The suction negative pressure acting on the suction chamber 15 sucks a part of the dust on the cleaning surface S directly into the suction chamber 15 together with air (air), while the cleaning surface S is scraped up by the main rotary cleaning body 18. Dust is sucked into the suction chamber 15 together with air.
The air containing dust sucked into the suction chamber 15 is sucked into the paper pack filter 4 via the connection pipe 17, the extension pipe 9, the hand operation pipe 8 and the dust collecting hose 7, and the paper pack filter 4. Transparent.

この際、エアと共に吸い込まれる塵埃が紙パックフィルタ４に捕捉され、紙パックフィルタ４を透過する空気が清浄される。この清浄された空気は、電動送風機５に吸い込まれて内部を冷却した後、最終的に外部に排気される。   At this time, the dust sucked together with the air is captured by the paper pack filter 4 and the air passing through the paper pack filter 4 is cleaned. The purified air is sucked into the electric blower 5 to cool the inside, and is finally exhausted to the outside.

従って、吸込口体１０の吸込口本体１０ａを清掃面Ｓに沿って前進移動させることにより、通常の状態での清掃を行うことができる。
（２）回転清掃体１８のメンテナンス
また、このような清掃作業に伴い、回転清掃体１８に糸くずや髪の毛等の塵埃が巻き付いたり、回転清掃体１８のブラシ毛帯１８ｂに埃や細かい塵埃が付着して、ブラシ毛帯１８ｂによる塵埃掻き上げ効率が低下する。 Therefore, by moving the suction port body 10a of the suction port body 10 along the cleaning surface S, cleaning in a normal state can be performed.
(2) Maintenance of the rotary cleaning body 18 In addition, along with such cleaning work, dust such as lint and hair wraps around the rotary cleaning body 18 or dust and fine dust are collected on the brush band 18b of the rotary cleaning body 18. It adheres and the dust scraping efficiency by the brush bristle band 18b is lowered.

この場合には、電動送風機５及び駆動モータ２１が作動している状態で、メンテナンス用スイッチ２９をＯＮさせ、このＯＮ信号を演算制御回路３０に入力する。これにより演算制御回路３０は、駆動モータ２１を逆転制御して、回転清掃体１８を前進方向とは反対方向、即ち図５の矢印Ａ２で示した反時計回り方向に回転させる。   In this case, the maintenance switch 29 is turned on while the electric blower 5 and the drive motor 21 are operating, and this ON signal is input to the arithmetic control circuit 30. Thereby, the arithmetic control circuit 30 controls the drive motor 21 in the reverse direction to rotate the rotary cleaning body 18 in the direction opposite to the forward direction, that is, in the counterclockwise direction indicated by the arrow A2 in FIG.

一方、演算制御回路３０は、メンテナンス用スイッチ２９のＯＮ信号を受けて、ソレノイド２７を駆動させ、塵埃掻落蓋２５の先端に回転清掃体１８のブラシ毛帯１８ｂが当たるまでソレノイド２７により塵埃掻落蓋２５を回転清掃体１８側に回動させる。これにより、回転清掃体１８に巻き付いた糸くずや髪の毛等の塵埃或いは回転清掃体１８のブラシ毛帯１８ｂに付着した埃や細かい塵埃が塵埃掻落蓋２５により掻き落とされることになる。   On the other hand, the arithmetic control circuit 30 receives the ON signal of the maintenance switch 29, drives the solenoid 27, and the dust 27 is removed by the solenoid 27 until the brush bristle band 18b of the rotary cleaning body 18 hits the tip of the dust removal cover 25. 25 is rotated to the rotary cleaning body 18 side. As a result, dust such as lint and hair wound around the rotary cleaning body 18 or dust and fine dust adhering to the brush band 18b of the rotary cleaning body 18 are scraped off by the dust scraping lid 25.

また、塵埃掻落蓋２５の回転清掃体１８側への回動により、塵埃掻落蓋２５と開口２４の下縁との間に空気導入口２８が形成されて、矢印Ａ３で示したように空気が吸込室１５の塵埃掻落蓋２５と回転清掃体１８との間に吸い込まれる。この吸い込まれた空気は、塵埃掻落蓋２５により掻き落とされた塵埃と共に吸込室１５の後部側に吸い込まれた後、接続パイプ１７，延長管９，手元操作パイプ８及び集塵ホース７を介して紙パックフィルタ４内に吸い込まれて、紙パックフィルタ４を透過する。   In addition, the dust scraping lid 25 is rotated toward the rotary cleaning body 18 to form an air inlet 28 between the dust scraping lid 25 and the lower edge of the opening 24, so that air flows as indicated by an arrow A3. It is sucked between the dust scraping lid 25 and the rotary cleaning body 18 in the suction chamber 15. The sucked air is sucked into the rear side of the suction chamber 15 together with the dust scraped off by the dust scraping lid 25, and then passes through the connection pipe 17, the extension pipe 9, the hand operation pipe 8 and the dust collecting hose 7. It is sucked into the paper pack filter 4 and passes through the paper pack filter 4.

この際、空気と共に吸い込まれる塵埃が紙パックフィルタ４に捕捉され、紙パックフィルタ４を透過するエアが清浄される。この清浄された空気は、電動送風機５に吸い込まれて内部を冷却した後、最終的に外部に排気される。このようにして回転清掃体１８に付着した塵埃が除去される。尚、このようなメンテナンスは定期的に行っても良い。   At this time, the dust sucked together with the air is captured by the paper pack filter 4 and the air passing through the paper pack filter 4 is cleaned. The purified air is sucked into the electric blower 5 to cool the inside, and is finally exhausted to the outside. In this way, dust adhering to the rotary cleaning body 18 is removed. Such maintenance may be performed periodically.

尚、ソレノイド２７は、吸込室１５内に配設しているが、前上ケース１４の上面側に設けることもできる。この場合には、ソレノイドが吸込室１５内の空気の流れの邪魔になることはない。
（変形例１）
以上説明した例では、前上ケース１４に開口２４を設けて、この開口２４の開閉を行う塵埃掻落蓋２５により回転清掃体１８に付着した塵埃を除去するようにしたが、必ずしもこの構成に限定されるものではない。 The solenoid 27 is disposed in the suction chamber 15, but may be provided on the upper surface side of the front upper case 14. In this case, the solenoid does not interfere with the air flow in the suction chamber 15.
(Modification 1)
In the example described above, the opening 24 is provided in the front upper case 14, and the dust adhering to the rotary cleaning body 18 is removed by the dust scraping lid 25 that opens and closes the opening 24. However, the present invention is not limited to this configuration. Is not to be done.

例えば、図７（ａ）に示したように前上ケース１４に回転清掃体１８側に向けて開口する空気導入口４０を設け、この空気導入口４０を塵埃掻落部材４１により開閉するようにしても良い。   For example, as shown in FIG. 7A, the front upper case 14 is provided with an air inlet 40 that opens toward the rotary cleaning body 18, and the air inlet 40 is opened and closed by a dust scraping member 41. Also good.

この場合も、空気導入口４０は回転清掃体１８のブラシ毛帯１８ｂを設けた部分に沿ってスリット状に形成されている。また、塵埃掻落部材４１は、図７（ａ）後縁部が前上ケース１４の内面に支持軸４２ａを介して回動自在に取り付けられた導入口開閉板４２と、この導入口開閉板４２の先端部に植毛された掻落用ブラシ４３を有する[図７（ｂ）参照]。尚、導入口開閉板４２は図示を省略したネジリコイルバネで空気導入口４０を閉成する方向に回動付勢されている。このネジリコイルバネは支持軸４２ａに捲回した状態で導入口開閉板４２と前上ケース１４との間に介装することができる。   Also in this case, the air inlet 40 is formed in a slit shape along a portion of the rotary cleaning body 18 where the brush hair band 18b is provided. Further, the dust scraping member 41 includes an inlet opening / closing plate 42 whose rear edge in FIG. 7A is rotatably attached to the inner surface of the front upper case 14 via a support shaft 42a, and the inlet opening / closing plate 42. The brush 43 for scraping planted in the front-end | tip part of the [refer FIG.7 (b)]. The inlet opening / closing plate 42 is urged to rotate in a direction to close the air inlet 40 by a torsion coil spring (not shown). The torsion coil spring can be interposed between the inlet opening / closing plate 42 and the front upper case 14 while being wound around the support shaft 42a.

また、前上ケース１４の内面には支持突部４４が形成され、この支持突部４４にはソレノイド４５が取り付けられている。このソレノイド４５は、図９に示したメンテナンス用スイッチ２９がＯＮさせられたときに演算制御回路３０により作動制御されて、作動時に塵埃掻落部材４１を図８に示したように回転清掃体１８側に回動させるようになっている。   Further, a support protrusion 44 is formed on the inner surface of the front upper case 14, and a solenoid 45 is attached to the support protrusion 44. The solenoid 45 is controlled by the arithmetic control circuit 30 when the maintenance switch 29 shown in FIG. 9 is turned on, and the dust scraping member 41 is moved to the side of the rotary cleaning body 18 as shown in FIG. It is designed to be rotated.

尚、この変形例でも演算制御回路３０は、通常の清掃時に回転清掃体１８を図７（ａ）に矢印Ａ１で示したように吸込口体１０の前進方向に回転させるようにしている。また、通常の清掃時には、塵埃掻落部材４１の導入口開閉板４２が図示しないネジリコイルバネのバネ力で空気導入口４０を閉成するようになっている。   In this modification as well, the arithmetic control circuit 30 rotates the rotary cleaning body 18 in the forward direction of the suction port 10 as indicated by an arrow A1 in FIG. Further, during normal cleaning, the inlet opening / closing plate 42 of the dust scraping member 41 closes the air inlet 40 by the spring force of a torsion coil spring (not shown).

このような構成においては、メンテナンス用スイッチ２９がＯＮさせられると、このＯＮ信号が演算制御回路３０に入力される。この演算制御回路３０は、メンテナンス用スイッチ２９がＯＮ信号を受けると、駆動モータ２１を逆転させて、回転清掃体１８を図８に示したように逆回転させる。   In such a configuration, when the maintenance switch 29 is turned ON, this ON signal is input to the arithmetic control circuit 30. When the maintenance switch 29 receives the ON signal, the arithmetic control circuit 30 reverses the drive motor 21 and rotates the rotary cleaning body 18 in the reverse direction as shown in FIG.

これに伴い演算制御回路３０は、ソレノイド４５を作動させて、塵埃掻落部材４１の掻落用ブラシ４３に回転清掃体１８のブラシ毛帯１８ｂが当たるまで、ソレノイド４５により塵埃掻落部材４１を図８に示したように回転清掃体１８側に回動させる。そして、回転清掃体１８の逆回転により、この回転清掃体１８のブラシ毛帯１８ｂの塵埃が掻落用ブラシ４３により梳かれて、回転清掃体１８のブラシ毛帯１８ｂに付着した塵埃が掻き落とされる。   Accordingly, the arithmetic control circuit 30 operates the solenoid 45 to move the dust scraping member 41 to the scraping brush 43 of the dust scraping member 41 by the solenoid 45 in FIG. As shown, it is turned to the rotary cleaning body 18 side. Then, due to the reverse rotation of the rotary cleaning body 18, dust on the brush band 18 b of the rotary cleaning body 18 is scratched by the scraping brush 43, and dust adhering to the brush band 18 b of the rotary cleaning body 18 is scraped off. .

一方、この回動により、空気導入口４０が開かれて、空気導入口４０から空気が図８の矢印Ａ４で示したように略掻落用ブラシ４３とブラシ毛帯１８ｂとの接触する方向に向けて吸い込まれる。この吸い込まれた空気は、掻落用ブラシ４３により回転清掃体１８のブラシ毛帯１８ｂから掻き落とされた塵埃と共に吸込室１５の後部側に流れた後、図１の接続パイプ１７，延長管９，手元操作パイプ８及び集塵ホース７を介して紙パックフィルタ４内に吸い込まれて、紙パックフィルタ４を透過する。   On the other hand, by this rotation, the air introduction port 40 is opened, and the air from the air introduction port 40 is directed in the direction in which the brush 43 for scraping and the brush bristle band 18b come into contact with each other as shown by an arrow A4 in FIG. And sucked. The sucked air flows to the rear side of the suction chamber 15 together with dust scraped from the brush bristle band 18b of the rotary cleaning body 18 by the scraping brush 43, and then the connection pipe 17, the extension pipe 9, FIG. It is sucked into the paper pack filter 4 through the hand operation pipe 8 and the dust collecting hose 7 and passes through the paper pack filter 4.

この際、空気と共に吸い込まれる塵埃が紙パックフィルタ４に捕捉され、紙パックフィルタ４を透過するエアが清浄される。この清浄された空気は、電動送風機５に吸い込まれて内部を冷却した後、最終的に外部に排気される。このようにして回転清掃体１８に付着した塵埃が除去される。   At this time, the dust sucked together with the air is captured by the paper pack filter 4 and the air passing through the paper pack filter 4 is cleaned. The purified air is sucked into the electric blower 5 to cool the inside, and is finally exhausted to the outside. In this way, dust adhering to the rotary cleaning body 18 is removed.

尚、この変形例でも、図１〜図６に示した構成と同一部分又は類似する部分には図１〜図６に示した符号と同一の符号を付して、その説明を省略した。
（変形例２）
以上説明した例では、塵埃掻落蓋２５や塵埃掻落部材４１等の可動部材を用いて、メンテナンス時に回転清掃体１８に付着した塵埃を掻き落とすようにした例を示したが、必ずしもこの構成に限定されるものではない。 In this modification as well, the same or similar parts as those shown in FIGS. 1 to 6 are denoted by the same reference numerals as those shown in FIGS. 1 to 6 and the description thereof is omitted.
(Modification 2)
In the example described above, an example in which dust attached to the rotary cleaning body 18 is scraped off using a movable member such as the dust scraping lid 25 and the dust scraping member 41 is shown. However, the present invention is not limited to this configuration. Is not to be done.

例えば、図１０（ａ）に示したように、前上ケース１４の中間部に前下方に傾斜する傾斜内面１４ｂを設けて、この傾斜内面１４ｂに回転清掃体１８側に突出する突部４６を設け、この突部４６の前端部に掻落用ブラシ４７を植毛した構成としても良い。   For example, as shown in FIG. 10A, an inclined inner surface 14b inclined forward and downward is provided in the middle portion of the front upper case 14, and a protruding portion 46 protruding toward the rotary cleaning body 18 is provided on the inclined inner surface 14b. It is good also as a structure which provided and brushed the brush 47 for scraping in the front-end part of this protrusion 46. FIG.

この場合、突部４６及び掻落用ブラシ４７は回転清掃体１８のブラシ毛帯１８ｂに沿って設けられる[図１０（ｂ）参照]。しかも、掻落用ブラシ４７は、図１０（ａ）の矢印Ａ１で示したように回転清掃体１８の前進方向への回転時には、回転清掃体１８のブラシ毛帯１８ｂが滑らかに接触でき、回転清掃体１８が逆回転させられた時には、先端が回転清掃体１８のブラシ毛帯１８ｂを梳くように作用するようになっている。そして、回転清掃体１８のブラシ毛帯１８ｂから掻き落とされた塵埃は、空気と共に吸込室１５の後部に吸い込まれた後、図１の接続パイプ１７,延長管９，手元操作パイプ８及び集塵ホース７を介して紙パックフィルタ４内に吸い込まれて、紙パックフィルタ４を透過する。   In this case, the protrusion 46 and the brush 47 for scraping are provided along the brush band 18b of the rotary cleaning body 18 [see FIG. 10B]. Moreover, the brush 47 for scraping can be smoothly contacted with the brush band 18b of the rotary cleaning body 18 when the rotary cleaning body 18 rotates in the forward direction as indicated by an arrow A1 in FIG. When the body 18 is rotated in the reverse direction, the tip acts so as to scratch the brush bristle band 18b of the rotary cleaning body 18. And the dust scraped off from the brush band 18b of the rotary cleaning body 18 is sucked into the rear part of the suction chamber 15 together with the air, and then the connection pipe 17, the extension pipe 9, the hand operation pipe 8 and the dust collecting pipe of FIG. It is sucked into the paper pack filter 4 through the hose 7 and passes through the paper pack filter 4.

この際、空気と共に吸い込まれる塵埃が紙パックフィルタ４に捕捉され、紙パックフィルタ４を透過するエアが清浄される。この清浄された空気は、電動送風機５に吸い込まれて内部を冷却した後、最終的に外部に排気される。このようにして回転清掃体１８に付着した塵埃が除去される。   At this time, the dust sucked together with the air is captured by the paper pack filter 4 and the air passing through the paper pack filter 4 is cleaned. The purified air is sucked into the electric blower 5 to cool the inside, and is finally exhausted to the outside. In this way, dust adhering to the rotary cleaning body 18 is removed.

尚、この変形例でも、図１〜図６に示した構成と同一部分又は類似する部分には図１〜図６に示した符号と同一の符号を付して、その説明を省略した。
（変形例３）
また、変形例２では、塵埃掻落蓋２５や塵埃掻落部材４１等の可動部材を用いて、メンテナンス時に回転清掃体１８に付着した塵埃を掻き落とすようにした例を示したが、前上ケース１４の内面に固定した傾斜する掻落用ブラシ４７を用いて回転清掃体１８に付着した塵埃を掻き落とすようにしたが、必ずしもこの構成に限定されるものではない。 In this modification as well, the same or similar parts as those shown in FIGS. 1 to 6 are denoted by the same reference numerals as those shown in FIGS. 1 to 6 and the description thereof is omitted.
(Modification 3)
In the second modification, an example in which dust attached to the rotary cleaning body 18 is scraped off using a movable member such as the dust scraping lid 25 and the dust scraping member 41 is shown. The dust attached to the rotary cleaning body 18 is scraped off by using the sloping scraping brush 47 fixed to the inner surface of the rotary cleaning body 18, but is not necessarily limited to this configuration.

例えば、図１１（ａ）に示したように、前上ケース１４の中間部に前斜め下方に傾斜する傾斜内面１４ｂを設けて、この傾斜内面１４ｂに回転清掃体１８側に図１１（ｂ）に示したような櫛歯４８を設けた構成としても良い。   For example, as shown in FIG. 11 (a), an inclined inner surface 14b that is inclined obliquely forward and downward is provided in the middle portion of the front upper case 14, and the inclined inner surface 14b is disposed on the rotary cleaning body 18 side as shown in FIG. 11 (b). It is good also as a structure which provided the comb-tooth 48 as shown in.

この場合、櫛歯４８は、後側から前側に向けて回転清掃体１８側に傾斜する傾斜ガイド辺（傾斜ガイド部）４８ａと、傾斜ガイド辺４８ａの前端から傾斜内面１４ｂに対して略垂直に設けられた塵埃掻落辺（塵埃掻落部）４８ｂを設けた構成としても良い。   In this case, the comb teeth 48 are substantially perpendicular to the inclined inner surface 14b from the front end of the inclined guide side 48a and the inclined guide side 48a inclined toward the rotary cleaning body 18 from the rear side toward the front side. It is good also as a structure which provided the dust dust side (dust scraping part) 48b provided.

このような構成において、図１１（ａ）の矢印Ａ１で示したように回転清掃体１８の前進方向への回転時には、回転清掃体１８のブラシ毛帯１８ｂが櫛歯４８は傾斜ガイド辺４８ａの作用により櫛歯４８に滑らかに接触でき、回転清掃体１８が逆回転させられた時には、先端の塵埃掻落辺４８ｂが回転清掃体１８のブラシ毛帯１８ｂを梳くように作用するようになっている。   In such a configuration, as indicated by the arrow A1 in FIG. 11A, when the rotary cleaning body 18 rotates in the forward direction, the brush bristle band 18b of the rotary cleaning body 18 has the comb teeth 48 of the inclined guide side 48a. Due to the action, the comb teeth 48 can be smoothly contacted, and when the rotary cleaning body 18 is reversely rotated, the dust scraping side 48b at the tip acts so as to scratch the brush hair band 18b of the rotary cleaning body 18. .

そして、回転清掃体１８のブラシ毛帯１８ｂから掻き落とされた塵埃は、空気と共に吸込室１５の後部に吸い込まれた後、図１の接続パイプ１７延長管９，手元操作パイプ８及び集塵ホース７を介して紙パックフィルタ４内に吸い込まれて、紙パックフィルタ４を透過する。   And the dust scraped off from the brush band 18b of the rotary cleaning body 18 is sucked into the rear part of the suction chamber 15 together with air, and then the connection pipe 17 extension pipe 9, the hand operation pipe 8 and the dust collecting hose of FIG. 7 is sucked into the paper pack filter 4 through 7 and passes through the paper pack filter 4.

この際、空気と共に吸い込まれる塵埃が紙パックフィルタ４に捕捉され、紙パックフィルタ４を透過するエアが清浄される。この清浄された空気は、電動送風機５に吸い込まれて内部を冷却した後、最終的に外部に排気される。このようにして回転清掃体１８に付着した塵埃が除去される。   At this time, the dust sucked together with the air is captured by the paper pack filter 4 and the air passing through the paper pack filter 4 is cleaned. The purified air is sucked into the electric blower 5 to cool the inside, and is finally exhausted to the outside. In this way, dust adhering to the rotary cleaning body 18 is removed.

尚、この変形例でも、図１〜図６に示した構成と同一部分又は類似する部分には図１〜図６に示した符号と同一の符号を付して、その説明を省略した。   In this modification as well, the same or similar parts as those shown in FIGS. 1 to 6 are denoted by the same reference numerals as those shown in FIGS. 1 to 6 and the description thereof is omitted.

以上説明したように、この発明の実施の形態の電気掃除機用吸込口体は、吸込室１５が設けられ且つ前記吸込室１５の吸込開口１５ａが底面に開口する吸込口本体１０ａと、前記吸込開口１５ａに沿って配設された回転清掃体１８と、前記回転清掃体１８を回転駆動する駆動モータ２１を備えている。しかも、前記回転清掃体１８は、前記吸込口本体１０ａに回転自在に取り付けられ且つ前記駆動モータ２１に連動する回転軸１８ａと、前記回転軸１８ａに沿って半径方向に突出するように取り付けられた塵埃掻き上げ部材（ブラシ毛帯１８ｂ）を有する。さらに、電気掃除機用吸込口体は、前記回転清掃体１８を逆回転させたときに前記塵埃掻き上げ部材（ブラシ毛帯１８ｂ）に付着する塵埃を掻落可能な塵埃掻落部材（塵埃掻落蓋２５，塵埃掻落部材４１，掻落用ブラシ４７，櫛歯４８）が前記吸込室１５の上壁（前上ケース１４）に設けられていると共に、前記回転清掃体１８を前進方向とは反対方向に逆回転させる操作手段（メンテナンス用スイッチ２９）が設けられている。   As described above, the suction port body for the vacuum cleaner according to the embodiment of the present invention includes the suction port main body 10a in which the suction chamber 15 is provided and the suction opening 15a of the suction chamber 15 opens on the bottom surface, and the suction port. A rotary cleaning body 18 disposed along the opening 15a and a drive motor 21 that rotationally drives the rotary cleaning body 18 are provided. In addition, the rotary cleaning body 18 is rotatably attached to the suction port body 10a and is attached so as to protrude in the radial direction along the rotary shaft 18a. A dust scraping member (brush band 18b) is included. Further, the vacuum cleaner suction port body has a dust scraping member (dust scraping lid 25) that can scrape dust adhering to the dust scooping member (brush bristles 18b) when the rotary cleaning body 18 is reversely rotated. , A dust scraping member 41, a scraping brush 47, and comb teeth 48) are provided on the upper wall (front upper case 14) of the suction chamber 15, and the rotary cleaning body 18 is reversed in the direction opposite to the forward direction. An operating means for rotating (maintenance switch 29) is provided.

この構成によれば、操作手段を操作（メンテナンス用スイッチ２９をＯＮ）して回転清掃体１８を逆回転させることにより、前記塵埃掻き上げ部材（ブラシ毛帯１８ｂ）が塵埃掻落部材（２５，４１，４７，４８）に接触して、前記塵埃掻き上げ部材（ブラシ毛帯１８ｂ）に付着した塵埃を塵埃掻落部材（２５，４１，４７，４８）により掻き落とすことができるので、手間がかからず塵埃を回転清掃体１８から容易に除去できる。   According to this configuration, by operating the operating means (turning on the maintenance switch 29) and rotating the rotary cleaning body 18 in the reverse direction, the dust scooping member (brush bristles 18b) becomes the dust scrubbing members (25, 41). , 47, 48), and the dust adhering to the dust scraping member (brush band 18b) can be scraped off by the dust scraping member (25, 41, 47, 48). The dust can be easily removed from the rotary cleaning body 18.

また、この発明の実施の形態の電気掃除機用吸込口体において、前記塵埃掻落部材（塵埃掻落蓋２５，塵埃掻落部材４１）は前記回転清掃体１８に対して進退動可能に前記上壁（前上ケース１４）に取り付けられていると共に、前記操作手段（メンテナンス用スイッチ２９）が操作されたときに前記塵埃掻落部材（塵埃掻落蓋２５，塵埃掻落部材４１）を前記回転清掃体１８側に進出させる駆動手段（ソレノイド２７，４５）が設けられている。   In the vacuum cleaner suction port according to the embodiment of the present invention, the dust scraping member (dust scraping lid 25, dust scraping member 41) can move forward and backward with respect to the rotary cleaning body 18 (the upper wall). It is attached to the front upper case 14), and when the operation means (maintenance switch 29) is operated, the dust scraping member (dust scraping cover 25, dust scraping member 41) is moved to the rotary cleaning body 18 side. Drive means (solenoids 27 and 45) for advancing are provided.

この構成によれば、通常の清掃時には塵埃掻落部材（塵埃掻落蓋２５，塵埃掻落部材４１）が回転清掃体１８の回転を阻害しないので、回転清掃体１８にかかる負荷が増大せず、駆動モータ２１にかかる負荷が増大せず、消費電力が増加しない。   According to this configuration, since the dust scraping member (dust scraping lid 25, dust scraping member 41) does not hinder the rotation of the rotary cleaning body 18 during normal cleaning, the load applied to the rotary cleaning body 18 does not increase, and the drive motor 21 does not increase the load and power consumption does not increase.

また、この発明の実施の形態の電気掃除機用吸込口体において、前記塵埃掻落部材（掻落用ブラシ４７，櫛歯４８）は、前記回転清掃体１８の正回転時に前記塵埃掻き上げ部材（ブラシ毛帯１８ｂ）に滑らかに接触し、且つ前記回転清掃体１８の逆回転時に前記塵埃掻き上げ部材（ブラシ毛帯１８ｂ）に付着した塵埃を掻落し可能に設けられている。   In the vacuum cleaner suction port according to the embodiment of the present invention, the dust scraping member (scraping brush 47, comb tooth 48) is the dust scraping member (brush) when the rotary cleaning body 18 is rotated forward. The bristles 18b are in smooth contact with the bristles 18b, and are capable of scraping off dust adhering to the dust scooping member (brush bristles 18b) when the rotary cleaning body 18 rotates in the reverse direction.

この構成によれば、簡単な構成で、塵埃掻き上げ部材（ブラシ毛帯１８ｂ）に付着した塵埃を掻き落とすことができる。   According to this configuration, it is possible to scrape off dust adhering to the dust scraping member (brush hair band 18b) with a simple configuration.

また、この発明の実施の形態の電気掃除機用吸込口体において、前記上壁（前上ケース１４）に空気導入口４０が形成されていると共に、前記回転清掃体１８の正回転時に前記空気導入口４０を閉成し且つ前記回転清掃体１８の逆回転時に前記空気導入口（２８，４０）を開く塵埃掻落部材（塵埃掻落蓋２５，塵埃掻落部材４１）が設けられている。   In the vacuum cleaner suction port according to the embodiment of the present invention, an air inlet 40 is formed in the upper wall (front upper case 14), and the air is rotated when the rotary cleaner 18 is rotated forward. A dust scraping member (dust scraping lid 25, dust scraping member 41) is provided that closes the inlet 40 and opens the air inlet (28, 40) when the rotary cleaning body 18 rotates in the reverse direction.
