Description

本発明は、吸込口に回転ブラシを有する電気掃除機用吸込口体及びそれを用いた電気掃除機に関する。   The present invention relates to a suction port body for a vacuum cleaner having a rotating brush at a suction port, and a vacuum cleaner using the same.

従来の電気掃除機用吸込口体は特許文献１に開示されている。この電気掃除機用吸込口体は床面に対向する吸込口を筐体の底面前部に開口し、吸込口内には回転ブラシが配される。筐体の後部には回転ブラシを駆動する駆動基板が配される。駆動基板の下方には上下動可能なローラーが配される。駆動基板の上面には回転ブラシの駆動回路を形成する複数の電子部品が実装される。駆動基板の下面にはローラーの上下動を検知する検知スイッチが設けられる。   A conventional suction port for a vacuum cleaner is disclosed in Patent Document 1. This vacuum cleaner suction port body has a suction port facing the floor surface opened at the front part of the bottom surface of the housing, and a rotating brush is disposed in the suction port. A drive substrate for driving the rotating brush is disposed at the rear of the housing. A roller capable of moving up and down is disposed below the drive substrate. A plurality of electronic components forming a rotary brush drive circuit are mounted on the upper surface of the drive substrate. A detection switch for detecting the vertical movement of the roller is provided on the lower surface of the drive substrate.

電気掃除機用吸込口体が床面に接地されるとローラーが上昇し、電気掃除機用吸込口体を床面から離すとローラーが下降する。ローラーの上昇を検知スイッチで検知すると回転ブラシを駆動することができる。また、ローラーの下降を検知スイッチで検知すると駆動中の回転ブラシが停止される。これにより、電気掃除機用吸込口体を床面から離した際に回転ブラシを停止して安全性を確保することができる。   When the vacuum cleaner suction port is grounded to the floor, the roller rises, and when the vacuum cleaner suction port is moved away from the floor, the roller descends. When the rising of the roller is detected by the detection switch, the rotating brush can be driven. Further, when the lowering of the roller is detected by the detection switch, the rotating brush being driven is stopped. Thereby, when the suction opening for vacuum cleaners is separated from the floor surface, the rotating brush can be stopped to ensure safety.

特開平９−４７４０５号公報（第２頁−第４頁、第４図）Japanese Patent Laid-Open No. 9-47405 (pages 2 to 4 and FIG. 4)

しかしながら、上記従来の電気掃除機用吸込口体によると、駆動基板の下面に検知スイッチが実装され、上面に検知スイッチを除く各電子部品が実装される。このため、電気掃除機用吸込口体の高さが大きくなり、電気掃除機用吸込口体が大型化する問題があった。また、駆動基板に高価な両面基板を用いる必要があるため電気掃除機用吸込口体のコストが増大する問題もあった。   However, according to the conventional vacuum cleaner suction port body, the detection switch is mounted on the lower surface of the drive board, and each electronic component except the detection switch is mounted on the upper surface. For this reason, there existed a problem that the height of the suction inlet for vacuum cleaners became large, and the suction inlet for vacuum cleaners enlarged. Further, since it is necessary to use an expensive double-sided substrate for the driving substrate, there is a problem that the cost of the suction port for the vacuum cleaner increases.

本発明は、小型化及びコスト削減を図ることのできる電気掃除機用吸込口体及びそれを用いた電気掃除機を提供することを目的とする。   An object of this invention is to provide the suction inlet for vacuum cleaners which can achieve size reduction and cost reduction, and a vacuum cleaner using the same.

上記目的を達成するために本発明の電気掃除機用吸込口体は、床面に対峙する吸込口を底面に開口する筐体と、前記吸込口に配されてモータにより駆動される回転ブラシと、前記筐体の底面に上下移動可能に支持されるローラーと、電子部品を下面に実装して前記モータを駆動する片面基板から成る駆動基板とを備え、前記電子部品が前記ローラーの上下動を検知する検知スイッチを含むとともに、前記検知スイッチの検知結果に基づいて前記ローラーが下降したときに前記モータを停止して前記ローラーが上昇した際に前記モータを駆動することを特徴としている。   In order to achieve the above object, a vacuum cleaner suction port according to the present invention includes a housing that opens a suction port facing the floor surface on a bottom surface, a rotating brush that is disposed in the suction port and is driven by a motor. A roller that is supported on the bottom surface of the housing so as to be movable up and down, and a drive board that is composed of a single-sided board that drives the motor by mounting an electronic component on the lower surface, and the electronic component moves the roller up and down. In addition to a detection switch for detection, the motor is stopped when the roller is lowered based on the detection result of the detection switch, and the motor is driven when the roller is raised.

この構成によると、電気掃除機用吸込口体を接地するとローラーが上昇して検知スイッチにより検知され、駆動基板により駆動されるモータによって回転ブラシが回転する。これにより、カーペット等に埋没する塵埃が掻き上げられて吸込口から吸い込まれる。電気掃除機用吸込口体を床面から離すと、ローラーが下降して検知スイッチの検知によりモータが停止される。駆動基板は駆動回路を構成して検知スイッチを含む電子部品を下面に実装して筐体内に配され、筐体内の駆動基板よりも上方のスペースが削減される。   According to this configuration, when the vacuum cleaner suction port is grounded, the roller rises and is detected by the detection switch, and the rotating brush is rotated by the motor driven by the drive substrate. Thereby, the dust buried in the carpet or the like is scraped up and sucked from the suction port. When the vacuum cleaner suction port is moved away from the floor, the roller is lowered and the motor is stopped by detection of the detection switch. The drive board constitutes a drive circuit and an electronic component including a detection switch is mounted on the lower surface and arranged in the housing, and a space above the drive board in the housing is reduced.

また本発明は、上記構成の電気掃除機用吸込口体において、前記筐体の後部に設けられて前記吸込口から吸い込まれた気流が流出する傾倒自在の管状のパイプ部と、前記パイプ部に隣接して前記駆動基板が配される基板室とを備え、前記電子部品が前記パイプ部に配されるリード線の先端に設けられて前記駆動基板に電力を供給するコネクタを含み、前記ローラーが前記基板室内に突出して配されるとともに前記コネクタを前記ローラーと前記パイプ部との間に配置したことを特徴としている。   Further, the present invention relates to the suction port body for a vacuum cleaner having the above-described configuration, wherein the tiltable tubular pipe portion that is provided at the rear portion of the housing and from which the airflow sucked from the suction port flows out, and the pipe portion A board chamber in which the driving board is arranged adjacently, the electronic component including a connector that is provided at a tip of a lead wire arranged in the pipe portion and supplies power to the driving board, and the roller The connector is arranged so as to protrude into the substrate chamber, and the connector is disposed between the roller and the pipe portion.

この構成によると、駆動基板にはコネクタを先端に有するリード線を介して電力が供給される。コネクタは駆動基板の下面に取り付けられ、基板室内に突出するローラーとパイプ部との間に配される。これにより、コネクタとローラーとの干渉を回避して駆動基板を下方に配置できるとともにリード線を短縮できる。   According to this configuration, power is supplied to the drive board via the lead wire having the connector at the tip. The connector is attached to the lower surface of the drive substrate and is disposed between the roller protruding from the substrate chamber and the pipe portion. As a result, it is possible to avoid the interference between the connector and the roller, and to arrange the drive board downward, and to shorten the lead wire.

また本発明は、上記構成の電気掃除機用吸込口体において、前記電子部品が過電流を防止するポジスタを含み、前記筐体の上面に開口して前記筐体内に外気を取り込む冷却孔と、前記駆動基板の上面に配されて前記ポジスタの端子に連結される放熱板とを備えたことを特徴としている。   Further, the present invention relates to a vacuum cleaner suction port configured as described above, wherein the electronic component includes a posistor that prevents overcurrent, and a cooling hole that opens to the upper surface of the housing and takes outside air into the housing; And a heat radiating plate disposed on an upper surface of the driving substrate and connected to a terminal of the posistor.

この構成によると、駆動回路に過電流が流れるとポジスタによって電流が制限され、モータの過電流が防止される。この時、発熱するポジスタの端子に連結された放熱板が冷却孔から筐体内に流入する外気と熱交換して放熱する。   According to this configuration, when an overcurrent flows in the drive circuit, the current is limited by the posistor, and an overcurrent of the motor is prevented. At this time, the heat radiating plate connected to the terminal of the heat generating posistor exchanges heat with the outside air flowing into the housing from the cooling hole to radiate heat.

また本発明の電気掃除機は、上記各構成の電気掃除機用吸込口体を備えたことを特徴としている。   Moreover, the vacuum cleaner of the present invention is characterized by including the suction mouth for the vacuum cleaner having the above-described configuration.

本発明によると、回転ブラシのモータを駆動する駆動基板が検知スイッチを含む電子部品を下面に実装するので、筐体内の駆動基板よりも上方のスペースが削減される。従って、電気掃除機用吸込口体の小型化を図ることができる。また、駆動基板に片面基板を用いて電気掃除機用吸込口体のコストを削減することができる。   According to the present invention, since the drive board that drives the motor of the rotating brush mounts the electronic component including the detection switch on the lower surface, the space above the drive board in the housing is reduced. Accordingly, it is possible to reduce the size of the vacuum cleaner suction port. Moreover, the cost of the suction inlet for vacuum cleaners can be reduced by using a single-sided substrate for the drive substrate.

以下に本発明の実施形態を図面を参照して説明する。図１は一実施形態の電気掃除機の側面断面図を示している。電気掃除機１は電動送風機３を内装する本体部２を有し、本体部２には可撓性の接続ホース４が取り付けられる。接続ホース４の端部には延長管６が接続され、延長管６との接続部から分岐して使用者が把持する把持部５が設けられる。延長管６の先端には吸込口体１０が接続される。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1: has shown side surface sectional drawing of the vacuum cleaner of one Embodiment. The vacuum cleaner 1 has a main body 2 that houses an electric blower 3, and a flexible connection hose 4 is attached to the main body 2. An extension pipe 6 is connected to the end of the connection hose 4, and a gripping part 5 that is branched from the connection part with the extension pipe 6 and gripped by the user is provided. A suction port body 10 is connected to the tip of the extension pipe 6.

図２、図３、図４は吸込口体１０の側面図、上面図及び底面図を示している。吸込口体１０は樹脂成形品から成る筐体１１により覆われる。筐体１１は床面Ｆに対峙する吸込口１３を底面に開口した吸込部１１ａと、吸込部１１ａの中央部から後方に延びる延設部１１ｂとを有して平面視略Ｔ字状に形成される。吸込部１１ａの上面は冷却孔１１ｆを開口する上カバー１１ｅにより覆われている。吸込部１１ａの底面前端は後方が下がる傾斜面１１ｃに形成される。   2, 3, and 4 show a side view, a top view, and a bottom view of the suction port body 10. The suction inlet 10 is covered with a housing 11 made of a resin molded product. The housing 11 has a suction part 11a having a suction port 13 facing the floor F at the bottom and an extension part 11b extending rearward from the central part of the suction part 11a, and is formed in a substantially T shape in plan view. Is done. The upper surface of the suction part 11a is covered with an upper cover 11e that opens a cooling hole 11f. The front end of the bottom surface of the suction part 11a is formed on an inclined surface 11c whose back is lowered.

延設部１１ｂの上部には吸込口１３に連通して延長管６が接続される管状のパイプ部１２が設けられる。パイプ部１２は円筒面に形成された先端部１２ａ（図１参照）が筐体１１に設けた円筒面から成る支持部１１ｄにより支持される。先端部１２ａが支持部１１ｄの内面に摺動してパイプ部１２が筐体１１に対して回動中心１２ｂで前後方向に傾倒自在になってる。   A tubular pipe portion 12 that communicates with the suction port 13 and is connected to the extension tube 6 is provided on the upper portion of the extension portion 11b. The pipe portion 12 is supported by a support portion 11 d made of a cylindrical surface provided on the housing 11 at a tip end portion 12 a (see FIG. 1) formed on the cylindrical surface. The distal end portion 12a slides on the inner surface of the support portion 11d, and the pipe portion 12 is tiltable with respect to the casing 11 in the front-rear direction at the rotation center 12b.

吸込口１３には回転して塵埃を掻き上げる回転ブラシ１９が配される。筐体１１の底面には筐体１１の側面を開放して吸込口１３の後部側方に連通する吸気溝１４が凹設される。吸気溝１４を介して筐体１１の側方から塵埃を吸引することができる。筐体１１の前部には吸込口１３の両側方に起毛布１５が貼着される。起毛布１５は床面Ｆに平行な位置から傾斜面１１ｃまで延設される。起毛布１５はナイロン等の樹脂製の基体上にナイロンやフッ素樹脂等の耐摩耗性の高い繊維状の樹脂を植毛して形成される。   A rotary brush 19 that rotates to scrape dust is disposed at the suction port 13. The bottom surface of the housing 11 is recessed with an intake groove 14 that opens the side surface of the housing 11 and communicates with the rear side of the suction port 13. Dust can be sucked from the side of the housing 11 through the intake groove 14. Brushed cloths 15 are attached to the front part of the housing 11 on both sides of the suction port 13. The raised cloth 15 extends from a position parallel to the floor surface F to the inclined surface 11c. The raised cloth 15 is formed by implanting a fibrous resin having high wear resistance such as nylon or fluororesin on a resin base such as nylon.

起毛布１５の後方には筐体１１の両側部にローラー２１、２２が軸支される。ローラー２１、２２の前部は吸気溝１４内に突出して配される。筐体１１の延設部１１ｂの後端にはローラー２３が軸支され、支持部１１ｄよりも後方にローラー２３が配される。また、吸込部１１ａの後部には左右方向の一方に偏って上下移動可能なローラー２４が設けられる。吸込口体１０が床面Ｆに接地されるとローラー２４が上昇し、吸込口体１０が床面Ｆから離れるとローラー２４が自重により下降する。   Rollers 21 and 22 are pivotally supported on both sides of the casing 11 behind the raised cloth 15. The front portions of the rollers 21 and 22 are arranged so as to protrude into the intake groove 14. A roller 23 is pivotally supported at the rear end of the extending portion 11b of the housing 11, and the roller 23 is disposed behind the support portion 11d. In addition, a roller 24 is provided at the rear part of the suction part 11a so as to be able to move up and down in one direction in the left-right direction. When the suction port body 10 is grounded to the floor surface F, the roller 24 is raised, and when the suction port body 10 is separated from the floor surface F, the roller 24 is lowered by its own weight.

ローラー２１〜２４が床面Ｆに接地されることにより、吸込口１３が床面Ｆから所定距離だけ離れて平行に配されるように筐体１１の姿勢が保持される。この時、起毛布１５と床面Ｆとの間には所定量の隙間が形成され、起毛布１５と床面Ｆとの摺動が回避される。これにより、起毛布１５の摩耗が防止される。尚、吸込口体１０が前傾すると、起毛布１５が床面Ｆに摺動して床面Ｆの傷が防止される。   When the rollers 21 to 24 are grounded to the floor surface F, the posture of the housing 11 is maintained so that the suction port 13 is arranged in parallel with a predetermined distance away from the floor surface F. At this time, a predetermined amount of gap is formed between the raised cloth 15 and the floor surface F, and sliding between the raised cloth 15 and the floor surface F is avoided. Thereby, abrasion of the raised fabric 15 is prevented. In addition, when the suction inlet body 10 inclines forward, the raising cloth 15 will slide on the floor surface F, and the damage | wound of the floor surface F will be prevented.

図５、図６は吸込口体１０の上カバー１１ｅを取り外した上面図及び背面断面図を示している。吸込部１１ａの後部にはパイプ部１２を挟んでモータ１９ａ及び駆動基板３０が配される。モータ１９ａはベルト１９ｂを介して回転ブラシ１９に連結され、回転ブラシ１９を回転駆動する。   5 and 6 show a top view and a rear sectional view with the upper cover 11e of the suction port body 10 removed. A motor 19a and a drive board 30 are arranged behind the suction part 11a with the pipe part 12 interposed therebetween. The motor 19a is connected to the rotary brush 19 via the belt 19b, and rotates the rotary brush 19.

駆動基板３０は片面基板から成り、筐体１１内に設けられる基板室２７内に実装面を下方に向けて配される。基板室２７はパイプ部１２に隣接し、駆動基板３０を支持する複数のリブ２７ａが立設される。駆動基板３０にはモータ１９ａの駆動回路を構成する多数の電子部品３１が実装される。電子部品３１にはポジスタ３２、検知スイッチ３３及びコネクタ３４が含まれる。   The drive substrate 30 is a single-sided substrate, and is disposed in a substrate chamber 27 provided in the housing 11 with the mounting surface facing downward. The substrate chamber 27 is adjacent to the pipe portion 12, and a plurality of ribs 27 a that support the drive substrate 30 are provided upright. A large number of electronic components 31 constituting the drive circuit of the motor 19a are mounted on the drive board 30. The electronic component 31 includes a posistor 32, a detection switch 33, and a connector 34.

ポジスタ３２は駆動回路に過電流が流れると電流を制限し、モータ１９ａの過電流を防止する。検知スイッチ３３はローラー２４の軸部（不図示）に接触し、ローラー２４の上下動を検知する。コネクタ３４はパイプ部１２に沿って配されるリード線３５の先端に設けられる。リード線３５は延長管６及び接続パイプ４を介して本体部２内の制御部（不図示）に接続され、コネクタ３４によって駆動基板３０に電力が供給される。   When the overcurrent flows through the drive circuit, the posistor 32 limits the current and prevents the overcurrent of the motor 19a. The detection switch 33 is in contact with a shaft portion (not shown) of the roller 24 and detects the vertical movement of the roller 24. The connector 34 is provided at the tip of a lead wire 35 disposed along the pipe portion 12. The lead wire 35 is connected to a control unit (not shown) in the main body 2 via the extension pipe 6 and the connection pipe 4, and power is supplied to the drive board 30 by the connector 34.

ローラー２４は基板室２７内に突出して配され、コネクタ３４は駆動基板３０の端部に接続してローラー２４とパイプ部１２との間に配される。これにより、リード線３５を導出して高さが高くなるコネクタ３４とローラー２４との干渉を回避して駆動基板３０を下方に配置できるとともにリード線３５を短縮することができる。   The roller 24 is disposed so as to protrude into the substrate chamber 27, and the connector 34 is disposed between the roller 24 and the pipe portion 12 by being connected to an end portion of the driving substrate 30. As a result, it is possible to avoid the interference between the connector 34 and the roller 24, which are led out by leading the lead wire 35, and to arrange the drive substrate 30 downward, and to shorten the lead wire 35.

駆動基板３０から上方に突出して半田付けされるポジスタ３２の端子３２ａには絶縁体４１を介して放熱板４２が連結される。絶縁体４１は熱伝導性の高い樹脂等から成り、放熱板４２はアルミニウム等の金属から成る。   A heat radiating plate 42 is connected via an insulator 41 to the terminal 32a of the posistor 32 that protrudes upward from the drive substrate 30 and is soldered. The insulator 41 is made of a resin having high thermal conductivity, and the heat sink 42 is made of a metal such as aluminum.

上記構成の電気掃除機１において、電動送風機３の駆動によって吸込口１３から床面Ｆの塵埃が吸い込まれるとともに、吸気溝１４を介して吸込口体１０の側方の塵埃が吸い込まれて吸込口１３に導かれる。また、回転ブラシ１９によってカーペット等に埋没する塵埃が掻き上げられて吸込口１３から吸い込まれる。   In the vacuum cleaner 1 configured as described above, the dust on the floor surface F is sucked from the suction port 13 by the driving of the electric blower 3, and the dust on the side of the suction port body 10 is sucked through the suction groove 14 to suck the suction port. 13 leads to. Further, the dust buried in the carpet or the like is scraped up by the rotating brush 19 and sucked from the suction port 13.

吸込口１３から吸い込まれた塵埃はパイプ部１２から流出する。この時、冷却孔１１ｆから筐体１１内に外気が流入して駆動基板３０の上方を流通し、パイプ部１２に導かれる。駆動基板３０の上方を流通する空気は放熱板４２と熱交換し、放熱板４２から放熱してポジスタ３２が冷却される。パイプ部１２から流出する塵埃は延長管６及び接続ホース４を介して本体部２内に集塵される。   The dust sucked from the suction port 13 flows out from the pipe portion 12. At this time, outside air flows from the cooling hole 11 f into the housing 11, flows above the drive substrate 30, and is guided to the pipe portion 12. The air flowing above the drive substrate 30 exchanges heat with the heat radiating plate 42 and radiates heat from the heat radiating plate 42 to cool the posistor 32. Dust flowing out from the pipe portion 12 is collected in the main body portion 2 through the extension pipe 6 and the connection hose 4.

本実施形態によると、回転ブラシ１９のモータ１９ａを駆動する駆動基板３０が検知スイッチ３３を含む電子部品３１を下面に実装するので、筐体１１内の駆動基板３０よりも上方のスペースが削減される。従って、吸込口体１０の高さを小さくして小型化を図ることができる。また、駆動基板３０に片面基板を用いて吸込口体１０のコストを削減することができる。   According to the present embodiment, since the drive board 30 that drives the motor 19a of the rotary brush 19 mounts the electronic component 31 including the detection switch 33 on the lower surface, the space above the drive board 30 in the housing 11 is reduced. The Therefore, the suction port body 10 can be reduced in size by reducing the height. Moreover, the cost of the suction inlet 10 can be reduced by using a single-sided substrate for the drive substrate 30.

また、ローラー２４が基板室２７内に突出し、コネクタ３４をローラー２４とパイプ部１２との間に配置したので、コネクタ３４とローラー２４との干渉を回避して駆動基板３０を下方に配置できる。これにより、吸込口体１０の高さをより小さくできるとともに、リード線３５を短縮することができる。   Further, since the roller 24 protrudes into the substrate chamber 27 and the connector 34 is disposed between the roller 24 and the pipe portion 12, the drive substrate 30 can be disposed downward while avoiding interference between the connector 34 and the roller 24. Thereby, while being able to make the height of the suction inlet body 10 smaller, the lead wire 35 can be shortened.

また、筐体１１の上面に開口する冷却孔１１ｆと、駆動基板３０の上面に配されてポジスタ３２の端子３２ａに連結される放熱板４２とを備えたので、発熱するポジスタ３２を冷却してポジスタ３２を安定して動作させることができる。   Further, since the cooling hole 11f opened on the upper surface of the housing 11 and the heat radiating plate 42 arranged on the upper surface of the driving substrate 30 and connected to the terminal 32a of the posistor 32 are provided, the generated posistor 32 is cooled. The posistor 32 can be operated stably.

本発明によると、吸込口に回転ブラシを配した吸込口体を有する電気掃除機に利用することができる。   ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the vacuum cleaner which has a suction inlet body which has arrange | positioned the rotation brush to the suction inlet.
