Description

電気掃除機の吸込口ユニットおよび吸込口本体Suction port unit and main body of vacuum cleaner
　本発明は、電気掃除機のモータ駆動タイプの吸込口ユニット、および、異なる機能を有する複数の吸込口ユニットに共用できる電気掃除機の吸込口本体に関する。 The present invention relates to a motor-driven suction port unit of a vacuum cleaner and a suction port body of a vacuum cleaner that can be shared by a plurality of suction port units having different functions.
　電気掃除機の吸込口ユニットとして、例えば特許文献１には、フローリングや畳等の床面の清掃力を向上させるためにモータで回転駆動する回転ブラシを有する床面清掃用の吸込口ユニットが提案されている。この吸込口ユニットの場合、モータの回転力を回転ブラシに伝達するプーリおよびベルトを有する回転力伝達機構が回転ブラシと連結した状態で吸込口ユニットの筐体内に設けられている。 As an inlet unit of an electric vacuum cleaner, for example, Patent Document 1 proposes an inlet unit for cleaning a floor surface having a rotating brush that is rotationally driven by a motor in order to improve the cleaning power of the floor surface such as flooring and tatami mats. Has been. In the case of this suction port unit, a rotational force transmission mechanism having a pulley and a belt for transmitting the rotational force of the motor to the rotary brush is provided in the housing of the suction port unit in a state of being connected to the rotary brush.
　また、別の吸込口ユニットとして、特許文献２には、布団や毛布等の寝具上で振動するビータを備える寝具清掃用の吸込口ユニットが提案されている。この吸込口ユニットは、一対のばねおよび振動子の３点でビータを支持し、回転するカムによって振動子を介してビータを上下に振動させるように構成されている。 Also, as another suction port unit, Patent Document 2 proposes a suction port unit for bedding cleaning provided with a beater that vibrates on a bedding such as a futon or a blanket. This suction port unit is configured to support the beater at three points of a pair of springs and a vibrator, and to vibrate the beater up and down via the vibrator by a rotating cam.

　特許文献１の床面清掃用の吸込口ユニットを清掃する場合、通常、ユーザーは、筐体の底部に開口する集塵開口部から外部に露出する回転ブラシを刷毛やブラシ等の清掃具を用いて清掃する。あるいは、筐体の下ケース部から上ケース部を取り外し、回転力伝達機構のベルトを回転ブラシの一端に一体化されたプーリから外すことにより、回転ブラシを下ケース部から取り外して清掃することも可能である。しかしながら、下ケース部にはモータや回路基板等の電気部品が固定されているため、下ケース部内を清掃具にて清掃することはできても水洗いすることはできない。 When cleaning the suction port unit for cleaning the floor surface of Patent Document 1, the user usually uses a cleaning tool such as a brush or a brush to remove the rotating brush exposed to the outside from the dust collection opening that opens at the bottom of the housing. Clean. Alternatively, the rotary brush can be removed from the lower case part and cleaned by removing the upper case part from the lower case part of the housing and removing the belt of the rotational force transmission mechanism from the pulley integrated with one end of the rotary brush. Is possible. However, since electric parts such as a motor and a circuit board are fixed to the lower case portion, the inside of the lower case portion can be cleaned with a cleaning tool but cannot be washed with water.
　そのため、下ケース部内の隅部、電気部品と下ケース部との間の隙間等といった清掃具では届き難い箇所に入り込んだ塵埃、髪の毛や糸屑等の繊維状ゴミなどは除去されずに堆積する。また、吸込口ユニット内に残留した塵埃や繊維状ゴミに紛れて存在するダニや雑菌等が繁殖し易い。よって、このような不衛生な状態の吸込口ユニットを保管すると共に、使い続けなければならないという問題があった。 For this reason, dust that has been difficult to reach with cleaning tools such as corners in the lower case part, gaps between electrical parts and the lower case part, and fibrous dust such as hair and lint accumulate without being removed. . In addition, mites, germs, and the like that are confused with dust and fibrous dust remaining in the suction port unit easily propagate. Therefore, there is a problem that such an unsanitary suction port unit must be stored and used continuously.
　また、特許文献２の寝具清掃用の吸込口ユニットを清掃する場合、ビータを取り外して清掃することはできるが、吸込口ユニット内にはモータや回路基板等の電気部品が固定されているため、吸込口ユニット内を水洗いすることはできない。したがって、床面清掃用の吸込口ユニットと同様に、の寝具清掃用の吸込口ユニットも不衛生な状態の吸込口ユニットを保管すると共に、使い続けなければならないという問題があった。寝具清掃用の吸込口ユニットの場合、人の肌に触れる寝具を清掃するものであるため、特にこの問題の解決が望まれている。 In addition, when cleaning the suction port unit for cleaning the bedding of Patent Document 2, the beater can be removed and cleaned, but since electrical components such as a motor and a circuit board are fixed in the suction port unit, The inside of the inlet unit cannot be washed with water. Therefore, similarly to the floor cleaning suction port unit, the bedding cleaning suction port unit has a problem that the suction port unit in an unsanitary state must be stored and used continuously. In the case of the suction port unit for bedding cleaning, since the bedding that touches the human skin is cleaned, it is particularly desired to solve this problem.
　また、床面を清掃するときと寝具を清掃するときでは、衛生面、機能面等の観点から、被清掃面に応じた専用の吸込口ユニット（床面清掃用吸込口ユニットまたは寝具清掃用吸込口ユニット）を使用しなければならない。そのため、被清掃面に応じた専用の各吸込口ユニットにモータ、回路基板等の電気部品を設けなければならず、吸込口ユニットの製造コストが高くなるという問題もある。 Also, when cleaning the floor and bedding, from the standpoint of hygiene, function, etc., a dedicated suction port unit (floor surface suction port unit or bedding cleaning suction) according to the surface to be cleaned Mouth unit) must be used. For this reason, electrical components such as a motor and a circuit board must be provided in each dedicated suction port unit corresponding to the surface to be cleaned, which raises a problem that the manufacturing cost of the suction port unit increases.
　そこで、本発明者は、モータ、回路基板等の電気部品を内蔵する吸込口本体に、床面清掃用の清掃部材を有する装着ユニットと寝具清掃用の清掃部材を有する装着ユニットを付け替えるようにすることで、吸込口ユニットの製造コストを低減できることを見出した。 In view of this, the present inventor replaces the mounting unit having the cleaning member for cleaning the floor and the mounting unit having the cleaning member for cleaning the bedding into the suction port body containing the electric parts such as the motor and the circuit board. Thus, it has been found that the manufacturing cost of the inlet unit can be reduced.
　また、特許文献１の床面清掃用吸込口ユニットや特許文献２の寝具清掃用吸込口ユニットでは電気掃除機駆動時の気流を利用してモータや回路基板等の電気部品を冷却する冷却風路が設けられるのに対し、本発明者は吸込口本体内に冷却風路を設けることで前記電気部品を冷却できることを見出した。 In addition, the floor cleaning inlet unit of Patent Literature 1 and the bedding cleaning inlet unit of Patent Literature 2 use a cooling air passage that cools electric components such as a motor and a circuit board by using an air current when the vacuum cleaner is driven. However, the present inventor has found that the electrical component can be cooled by providing a cooling air passage in the suction port body.
　本発明は、このような課題に鑑みなされたものであり、機能が異なる装着ユニットを付け替えおよび水洗い可能であり、モータ駆動タイプでありながら低コストにて製造することができる電気掃除機の吸込口ユニットを提供することを目的とする。
　さらに、本発明は、床面清掃用の吸込口ユニットと寝具清掃用の吸込口ユニットに共用でき、かつ内蔵された電気部品を効率よく冷却することができる電気掃除機の吸込口本体を提供することを目的とする。 SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and can be used to replace a mounting unit having different functions and to be washed with water, and to be manufactured at a low cost while being a motor-driven type.

　また、本発明によれば、筐体と吸込口とを備える複数の清掃用の装着ユニットを選択的に装着可能な吸込口本体と、前記筐体内に設けられ前記装着ユニットを駆動するモータとを備え、
　前記筐体は、前記モータを収納するモータ収納室と、外部の空気を前記モータ収納室に吸気可能な吸気孔と、前記モータ収納室内を通過した空気を前記吸込口側へ排気可能な排気孔と有する電気掃除機の吸込口本体が提供される。 Thus, according to the present invention, the suction port body, and a mounting unit having a dust collection opening that is detachably mounted on the suction port body and communicates with the suction port,

A vacuum cleaner main body of the vacuum cleaner is provided.
　本発明の電気掃除機の吸込口ユニットによれば、モータ、回路基板等の電気部品が備えられた吸込口本体と、吸込口本体に装着される装着ユニットとが分離可能である。そのため、回動清掃部材を有する汚れやすい装着ユニットを吸込口本体から取り外して水洗いすることができ、装着ユニットを衛生的な状態で保管することができる。
　また、機能が異なる装着ユニットを吸込口本体に付け替えること、例えば、床面清掃用装着ユニットと寝具清掃用装着ユニットを選択的に吸込口本体に装着することが可能となる。したがって、電気部品を備えた吸込口本体を床面清掃用装着ユニットと寝具清掃用装着ユニットといった複数の異なる機能を有する装着ユニットに共用することが可能となるため、モータ駆動タイプでありながら、複数の異なる機能を有する装着ユニットを付け替え可能な吸込口ユニットを低コストにて製造することができる。 According to the suction port unit of the vacuum cleaner of the present invention, the suction port body provided with electric parts such as a motor and a circuit board can be separated from the mounting unit mounted on the suction port body. Therefore, it is possible to remove the mounting unit having a rotational cleaning member that is easily contaminated from the suction port body and wash it with water, and to store the mounting unit in a sanitary state.
Further, it is possible to replace the mounting unit having different functions with the suction port body, for example, to selectively mount the floor surface cleaning mounting unit and the bedding cleaning mounting unit to the suction port body.

［回転ブラシユニット］
　図８に示すように、回転ブラシユニット５１ｂは、回転ブラシ部５１ｂ1と、回転力伝達機構部５１ｂ2とを有してなる。 [Rotating brush unit]
As shown in FIG. 8, the rotating brush unit 51b includes a rotating brush part 51b 1 and a rotational force transmission mechanism part 51b 2 .
　回転ブラシ部５１ｂ1は、図示しない複数のブラシ部が外周面に設けられた軸部５１ｂ11と、軸部５１ｂ11の一端に回転可能に設けられた軸受部５１Ｂとを備え、軸部５１ｂ11の他端は回転力伝達機構部５１ｂ2と連結されている。 Rotary brush portion 51b 1 is provided with a shaft portion 51b 11 in which a plurality of brush unit (not shown) is provided on its outer surface and a bearing portion 51B rotatably provided on one end of the shaft portion 51b 11, the shaft portion 51b 11 the other end is connected to the rotational force transmitting mechanism portion 51b 2.
　図６と図７に示すように、回転力伝達機構部５１ｂ2は、ケース５１ｂ21内に回転可能に設けられた一対の平行な金属軸５１ｂ22、５１ｂ23に固着された大小のギヤ形プーリ５１ｂ25、５１ｂ26と、これらのプーリ５１ｂ25、５１ｂ26に巻き掛けられたベルト５１ｂ27と、小さいプーリ５１ｂ26と側の金属軸５１ｂ23に固着された後述する吸込口本体５２の駆動ギヤ部５２ａ2（図１０、図１１参照）と噛合可能なギヤ部５１ｂ28とを備える。なお、ケース部５１ｂ21には水抜き孔５１ｂ221が形成されている。 As shown in FIGS. 6 and 7, the rotational force transmission mechanism 51b 2 includes a large and small gear pulley fixed to a pair of parallel metal shafts 51b 22 and 51b 23 provided rotatably in the case 51b 21 . 51b 25 and 51b 26 , a belt 51b 27 wound around these pulleys 51b 25 and 51b 26 , and a drive gear portion of a suction port body 52, which will be described later, fixed to a small pulley 51b 26 and a metal shaft 51b 23 on the side. 52a 2 (see FIG. 10 and FIG. 11) and a gear portion 51b 28 that can be engaged with each other. The case 51b 21 is formed with a drain hole 51b 221 .
　このように構成された回転ブラシユニット５１ｂによれば、吸込口本体５２の駆動ギヤ部５２ａ2からの回転力がギヤ部５１ｂ28に伝達されて回転すると、その回転力がベルト５１ｂ27を介して回転ブラシ部５１ｂ1に伝達され、それによって回転ブラシ部５１ｂ1の軸部５１ｂ11が回転する。 According to the rotation brush unit 51b thus constructed, when the rotational force from the drive gear portion 52a 2 of the suction inlet main body 52 is rotated is transmitted to the gear portion 51b 28, the rotational force via the belt 51b 27 This is transmitted to the rotating brush portion 51b 1 , whereby the shaft portion 51b 11 of the rotating brush portion 51b 1 rotates.
［吸込口本体］
　図２～１１に示すように、吸込口本体５２は、全体の形状がＴ形であり、装着ユニット５１と着脱可能な第１筐体部５２ａと、第１筐体部５２ａの左右長手方向の中間部の後端側に前後軸心廻りに回動可能に接続された接続部５２ｂと、接続部５２ｂに対して揺動可能に接続された第２筐体部５２ｃとを備える。 [Suction port body]
As shown in FIGS. 2 to 11, the suction port main body 52 has a T shape as a whole, a first housing portion 52a that can be attached to and detached from the mounting unit 51, and a left and right longitudinal direction of the first housing portion 52a. A connecting portion 52b connected to the rear end side of the intermediate portion so as to be rotatable about the front-rear axis and a second housing portion 52c connected to the connecting portion 52b so as to be swingable.
　第１筐体部５２ａは、上ケース５２ａｃ1と下ケース５２ａｃ2とを組み付けて形成され、左右長手方向の中間部の前端側に開口する吸込口５２ａ1が形成されている。そして、この吸引口５２ａ1の周囲部にはパッキン５２ａ11が設けられると共に、パッキン５２ａ11の表面に摩擦低減膜が積層されている。この摩擦低減膜としては、例えば、ＰＥＴ（ポリエチレンテレフタレート）といった樹脂のフィルム、フッ素樹脂といった摩擦低減樹脂の塗膜等が用いられる。なお、第２筐体部５２ｃの内部は吸込口５２ａ1と連通する通風路となっている。また、吸引口５２ａ1は、清掃面に対して略垂直になっている。これにより、第１筐体部５２ａの吸引口５２ａ1と接続される装着ユニット側の開口部と接続される通風路の投影面積が少なくなることから第１筐体部５２ａのコンパクト化が図れる。 The first housing part 52a is formed by assembling the upper case 52Ac 1 and lower case 52Ac 2, inlet 52a 1 which is open at the front end side of the intermediate portions of the left and right longitudinal direction is formed. Then, the packing 52a 11 is provided on the periphery of the suction port 52a 1, friction-reducing film is laminated on the surface of the packing 52a 11. As the friction reducing film, for example, a resin film such as PET (polyethylene terephthalate), a coating film of friction reducing resin such as a fluororesin, or the like is used. Incidentally, the inside of the second housing portion 52c has a suction port 52a 1 and communicating with the ventilation passage. The suction port 52a 1 is substantially perpendicular to the cleaning surface. Accordingly, downsizing of the first housing portion 52a from the projected area of the air passage connected to the opening of the mounting unit side that is connected to a suction port 52a 1 of the first housing part 52a is reduced can be achieved.
　吸込口本体５２に装着ユニット５１を装着する際、吸込口本体５２のパッキン５２ａ11が装着ユニット５１の区画壁５１ａ13に摺接する。このとき、区画壁５１ａ13や切欠き５１ａ131の角部等に擦れたパッキン５２ａ11が剥がれたり傷が付くと、清掃時において、吸込口本体５２と装着ユニット５１の間の隙間付近の空気がパッキン５２ａ11の損傷箇所から吸引口５２ａ1に流入するおそれがあり、そうすると集塵開口部５１ｘから空気を吸引する吸引力が低下する。したがって、パッキン５２ａ11の損傷を抑制することによって不必要な箇所からの空気流入を抑制するために、パッキン５２ａ11の表面に摩擦低減膜が積層されている。 When the mounting unit 51 is mounted on the suction port body 52, the packing 52 a 11 of the suction port body 52 is in sliding contact with the partition wall 51 a 13 of the mounting unit 51. In this case, the partition wall 51a 13 and the packing 52a rubbed corners or the like of the notch 51a 131 11 peeling or scratched, at the time of cleaning, the air near the gap between the suction inlet main body 52 and the mounting unit 51 There is a possibility of flowing into the suction port 52a 1 from the damaged portion of the packing 52a 11 , and the suction force for sucking air from the dust collection opening 51x is reduced. Therefore, in order to suppress the inflow of air from unwanted locations by suppressing damage to the packing 52a 11, friction reducing film is laminated on the surface of the packing 52a 11.
　また、第１筐体部５２ａの右側部分には、回転ブラシユニット５１ｂのギヤ部５１ｂ23と噛合可能な駆動ギヤ部５２ａ2を回転させるモータＭ（図７参照）が内蔵されている。図１０、図１１（Ａ）および（Ｂ）に示すように、駆動ギヤ部５２ａ2は、冠歯車のように軸心方向に突出する複数の歯５２ａ21を有している。この歯５２ａ21は山形に形成されており、その山形における周方向の一面は軸心に対してほぼ平行な回転力伝達面５２ａ211であり、山形における周方向の他面は軸心に対して傾いた摺接面２ａ212となっている。また、駆動ギヤ部５２ａ2の軸心位置には筒部５２ａ22が設けられている。 On the right side portion of the first housing portion 52a, a motor M for rotating the gear portion 51b 23 capable of meshing drive gear portion 52a 2 of the rotation brush unit 51b (see FIG. 7) is incorporated. As shown in FIGS. 10, 11A and 11B, the drive gear portion 52a 2 has a plurality of teeth 52a 21 protruding in the axial direction like a crown gear. The teeth 52a 21 are formed in a chevron shape, one circumferential surface of the chevron is a rotational force transmitting surface 52a 211 substantially parallel to the axis, and the other circumferential surface in the chevron is in relation to the axis. An inclined sliding contact surface 2a 212 is formed. A cylindrical portion 52a 22 is provided at the axial center position of the drive gear portion 52a 2 .
　一方、前述の回転力伝達機構部５１ｂ2のギヤ部５１ｂ28（図８参照）は、駆動ギヤ部５２ａ2の各歯５２ａ21と噛合する冠歯車タイプの複数の歯を有すると共に、駆動ギヤ部５２ａ2の筒部５２ａ22が嵌り込む凹部を軸心位置に有している。また、回転力伝達機構部５１ｂ2のギヤ部５１ｂ28の各歯は、駆動ギヤ部５２ａ2の各歯５２ａ21の回転力伝達面５２ａ211と接触する回転力被伝達面と、駆動ギヤ部５２ａ2の各歯５２ａ21の摺接面５２ａ212と摺接する被摺接面を有している。すなわち、回転力伝達機構部５１ｂ2のギヤ部５１ｂ28は、駆動ギヤ部５２ａ2から筒部５２ａ22を取り除いたものである。 On the other hand, the gear portion 51b 28 (see FIG. 8) of the aforementioned rotational force transmission mechanism portion 51b 2 has a plurality of crown gear type teeth that mesh with the respective teeth 52a 21 of the drive gear portion 52a 2 , and the drive gear portion. A concave portion into which the cylindrical portion 52a 22 of 52a 2 is fitted has an axial center position. Further, each tooth of the gear portion 51b 28 of the rotational force transmission mechanism 51b 2 is connected to the rotational force transmission surface 52a 211 of each tooth 52a 21 of the drive gear portion 52a 2 and the drive gear portion 52a. Each of the two teeth 52a 21 has a sliding contact surface in sliding contact with the sliding contact surface 52a 212 . That is, the gear part 51b 28 of the rotational force transmission mechanism part 51b 2 is obtained by removing the cylindrical part 52a 22 from the drive gear part 52a 2 .
　また、第１筐体部５２ａの左側部分には、第１筐体部５２ａの底壁に形成した貫通孔を通って上下方向へ揺動可能に設けられた車輪５２ａ32を有する吸込可能状態検知部５２ａ3が設けられている。 In addition, the left side portion of the first casing 52a has a wheel 52a 32 provided so as to be swingable in the vertical direction through a through hole formed in the bottom wall of the first casing 52a. A part 52a 3 is provided.
　吸込口ユニット５が床面上に載置されると、吸込可能状態検知部５２ａ3の車輪５２ａ32が吸込口ユニット５の内部側へ揺動して引っ込む。これにより、吸込可能状態検知部５２ａ3のスイッチ５２ａ33がＯＮとなって検知信号を出力する。また、吸込口ユニット５が床面から浮き上がると車輪５２ａ32が外部へ突出する。これにより、吸込可能状態検知部５２ａ3のスイッチ５２ａ33がＯＦＦとなって検知信号の出力を停止する。なお、この検知信号は、例えば、掃除機本体２内に設けられた制御部（例えば、マイコン）に入力され、その検知信号に基づいて制御部はモータＭの駆動を制御する。 Once placed on the inlet unit 5 floor surface, retract the wheels 52a 32 of the suction state detecting portion 52a 3 is swung to the inner side of the inlet unit 5. As a result, the switch 52a 33 of the inhalable state detection unit 52a 3 is turned ON and a detection signal is output. Further, when the suction port unit 5 is lifted from the floor surface, the wheels 52a 32 protrude to the outside. As a result, the switch 52a 33 of the suckable state detector 52a 3 is turned OFF and the output of the detection signal is stopped. In addition, this detection signal is input into the control part (for example, microcomputer) provided in the cleaner body 2, for example, and a control part controls the drive of the motor M based on the detection signal.
　また、第１筐体部５２ａの左側部分であって吸込可能状態検知部５２ａ3の上方には、前記ロック部材５１ａ3にて装着ユニット５１を吸込口本体５２に固定した状態を検知するロック検知部５２ａｘ（図９、図１４参照）が設けられている。ロック検知部５２ａｘについて詳しくは後述する。なお、モータＭまたはロック検知部５２ａｘを制御する回路基板５２ａｐ（図５、図１６参照）がロック検知部５２ａｘの下方に設けられている。 In addition, a lock detection that detects a state in which the mounting unit 51 is fixed to the suction port body 52 by the lock member 51a 3 above the suction enabled state detection unit 52a 3 on the left side portion of the first housing 52a. A portion 52ax (see FIGS. 9 and 14) is provided. Details of the lock detector 52ax will be described later. A circuit board 52ap (see FIGS. 5 and 16) for controlling the motor M or the lock detection unit 52ax is provided below the lock detection unit 52ax.
　図４と図５に示すように、一方向に長い第１筐体部５２ａは、その一端側にモータＭを収納するモータ収納室５２ｍと、外部の空気をモータ収納室５２ｍに吸気可能な吸気孔５２ｍ1と、モータ収納室５２ｍ内を通過した空気を吸込口５２ａ1側へ排気可能な排気孔５２ｍ2と有している。 As shown in FIGS. 4 and 5, the first casing 52a that is long in one direction has a motor housing chamber 52m that houses the motor M at one end thereof, and an intake air that can suck external air into the motor housing chamber 52m. It has a hole 52m 1 and an exhaust hole 52m 2 through which air that has passed through the motor storage chamber 52m can be exhausted to the suction port 52a 1 side.
　具体的には、第１筐体部５２ａの右側部分にモータ収納室５２ｍが設けられ、モータＭはその出力軸Ｍｓの先端が第１筐体部５２ａの右側壁５２ｒｗを貫通するようにモータ収納室５２ｍに収納されている。なお、モータ収納室５２ｍにはモータＭを所定位置に位置決めする複数のリブが設けられている。 Specifically, the motor housing chamber 52m is provided in the right side portion of the first housing portion 52a, and the motor M houses the motor so that the tip of the output shaft Ms penetrates the right wall 52rw of the first housing portion 52a. It is stored in the chamber 52m. The motor storage chamber 52m is provided with a plurality of ribs for positioning the motor M at a predetermined position.
　吸気孔５２ｍ1は、モータ収納室５２ｍを構成する後壁５２ｂｗにおける右側壁５２ｒｗ寄りに形成されている。また、排気孔５２ｍ2は、モータ収納室５２ｍと吸込口５２ａ１との間の壁部５２ｘｗに形成されている。よって、モータＭの出力軸Ｍｓの先端は吸気孔５２ｍ1側に配置され、モータＭの出力軸Ｍｓの基端は排気孔５２ｍ2側に配置される。 The intake hole 52m 1 is formed closer to the right side wall 52rw in the rear wall 52bw constituting the motor storage chamber 52m. The exhaust hole 52m 2 is formed in the wall 52xw between the motor storage chamber 52m and the suction port 52a1. Therefore, the distal end of the output shaft Ms of the motor M is disposed on the intake hole 52m 1 side, and the proximal end of the output shaft Ms of the motor M is disposed on the exhaust hole 52m 2 side.
　これにより、図４と図５に示すように、電気掃除機１が駆動して吸込口５２ａ1内に空気が矢印Ａ方向に引き込まれると、モータ収納室５２ｍ内の空気が排気孔５２ｍ2から出て吸込口５２ａ1内へ引き込まれる。すると、モータ収納室５２ｍ内が負圧となり、外部の空気が吸気孔５２ｍ1を通ってモータ収納室５２ｍ内に流入する。モータ収納室５２ｍ内に空気が流入することにより、モータＭの内部および外部を空気が矢印Ｂ方向に通過するため、この気流によってモータＭが冷却される。 Thus, as shown in FIGS. 4 and 5, the air inlet 52a in one electric vacuum cleaner 1 is driven is pulled in the direction of arrow A, the air inside the motor housing chamber 52m from the exhaust hole 52m 2 It is drawn into the suction port 52a 1 out. Then, the motor housing chamber 52m is a negative pressure, and flows into the motor housing chamber 52m external air through the intake hole 52m 1. As air flows into the motor housing chamber 52m, air passes through the motor M in and out of the motor M in the direction of arrow B, so that the motor M is cooled by this airflow.
　なお、図４に示すように、吸込可能状態検知部５２ａ3およびロック検知部５２ａｘが収納された第１筐体部５２ａの左側部分にも吸気孔５２ｍ1および排気孔５２ｍ2が設けられており、モータＭの冷却と同様に空気流によって回路基板５２ａｐが冷却される。 As shown in FIG. 4, an intake hole 52m 1 and an exhaust hole 52m 2 are also provided on the left side portion of the first housing 52a in which the inhalable state detector 52a 3 and the lock detector 52ax are accommodated. Similarly to the cooling of the motor M, the circuit board 52ap is cooled by the air flow.
　図６～９に示すように、接続部５２ｂは、上ケース５２ｂｃ1と下ケース５２ｂｃ2とを組み付けて形成され、第１筐体部５２ａの左右長手方向の中間部の後端側に設けられた筒形部５２ａ4の内部に気密かつ回動可能に嵌め込まれる前接続部５２ｂ1と、凹曲面状の内面を有する前接続部５２ｂ1と連設された後接続部５２ｂ2とを有する。また、後接続部５２ｂ2の上部には切欠き５２ｂ21が形成されている。 As shown in FIGS. 6 to 9, the connecting portion 52b is formed by assembling the upper case 52bc 1 and the lower case 52bc 2 and is provided on the rear end side of the intermediate portion in the left-right longitudinal direction of the first housing portion 52a. The front connection part 52b 1 fitted in the inside of the cylindrical part 52a 4 so as to be airtight and turnable, and the rear connection part 52b 2 connected to the front connection part 52b 1 having a concave curved inner surface. Further, a notch 52b 21 is formed in the upper portion of the rear connection portion 52b 2 .
　第３筐体部５２ｃは、上ケース５２ｃｃ1と下ケース５２ｃｃ2とを組み付けて形成され、接続部５２ｂの後接続部５２ｂ2内に気密かつ揺動可能に嵌め込まれる前接続部５２ｃ1と、延長パイプ４と着脱可能に接続される後接続部５２ｃ2とを有する。後接続部５２ｃ2は、延長パイプ４の接続端子と電気的に接続可能な複数の接続端子５２ｃ21が設けられている。この接続端子５２ｃ21は、吸込可能状態検知部５２ａ3の検知信号を前記制御部に送出する信号送出部として機能すると共に、後述するロック検知部５２ａｘのロック検知信号を前記制御部に送出する信号送出部として機能する。 The third housing portion 52c is formed by assembling the upper case 52Cc 1 and the lower case 52Cc 2, a front connecting portion 52c 1 to be fitted to allow airtight and swung into the connecting portion 52 b 2 after the connection portion 52 b, and a connecting portion 52c 2 after being detachably connected with the extension pipe 4. The rear connection portion 52c 2 is provided with a plurality of connection terminals 52c 21 that can be electrically connected to the connection terminals of the extension pipe 4. The connection terminal 52c 21 functions as a signal sending unit that sends the detection signal of the suckable state detection unit 52a 3 to the control unit, and also sends a lock detection signal of a lock detection unit 52ax to be described later to the control unit. Functions as a sending unit.
［床面清掃用の装着ユニットの吸込口本体への装着］
　図１２（Ａ）は実施形態１における吸込口本体と装着ユニットが分離した状態、図１２（Ｂ）は吸込口本体に装着ユニットを装着する状態を示す図である。また、図１３は実施形態１における装着ユニットを吸込口本体に装着する状態を示す部分断面図である。また、図１４（Ａ）は実施形態１における吸込口ユニットに装着された装着ユニットをロック部材にてロックする前の状態、図１４（Ｂ）はロック後の状態を示す断面図である。 [Mounting the floor cleaning mounting unit to the inlet]
FIG. 12A is a diagram illustrating a state where the suction port main body and the mounting unit are separated from each other in the first embodiment, and FIG. 12B is a diagram illustrating a state where the mounting unit is mounted on the suction port main body. FIG. 13 is a partial cross-sectional view showing a state in which the mounting unit according to Embodiment 1 is mounted on the suction port body. FIG. 14A is a cross-sectional view showing a state before the mounting unit mounted on the suction port unit in Embodiment 1 is locked with a lock member, and FIG. 14B is a cross-sectional view showing the state after locking.
　吸込口本体５２に装着ユニット５１を装着する際は、図１２（Ａ）に示すように、装着ユニット５１の装着凹部５１ｚの上方に吸込口本体５２を移動させ、図１２（Ｂ）に示すように、吸込口本体５２の第１筐体部５２ａ1を装着ユニット５１の装着凹部５１ｚに挿入する。そして、図１３に示すように、吸込口本体５２を右方向へスライド移動させることにより、吸込口本体５２の駆動ギヤ部５２ａ2が回転ブラシユニット５１ｂのギヤ部５１ｂ26と噛合する。このとき、吸込可能状態検知部５２ａ3の車輪５２ａ32が、装着ユニット５１の前記窓部５１ａ111から下方外部へ突出する。 When the mounting unit 51 is mounted on the suction port body 52, as shown in FIG. 12A, the suction port body 52 is moved above the mounting recess 51z of the mounting unit 51, and as shown in FIG. to, inserting the first housing portion 52a 1 of the suction inlet main body 52 to the mounting recess 51z of the mounting unit 51. Then, as shown in FIG. 13, by sliding the suction port body 52 to the right, the drive gear portion 52a 2 of the suction port body 52 meshes with the gear portion 51b 26 of the rotating brush unit 51b. At this time, the wheels 52a 32 of the suckable state detection unit 52a 3 protrude downward from the window 51a 111 of the mounting unit 51.
　また、下ケース５１ａ1の複数の係止凸部５１ａ131が吸込口本体５２の複数の係止溝部５２ａ5に係止する。なお、図７（Ａ）と図７（Ｂ）に示すように、各係止溝部５２ａ5は横倒Ｌ形に形成されており、各係止溝部５２ａ5に嵌り込んだ各係止凸部５１ａ131が縦（上下）方向にスライドした後に横（左右）方向にスライドできる。 Further, the plurality of locking projections 51 a 131 of the lower case 51 a 1 are locked to the plurality of locking grooves 52 a 5 of the suction port body 52. As shown in FIGS. 7 (A) and 7 (B), each locking groove 52a 5 is formed in an overturned L shape, and each locking projection is fitted in each locking groove 52a 5. 51a 131 can slide in the horizontal (left and right) direction after sliding in the vertical (up and down) direction.
　また、吸込口本体５２を装着ユニット５１に対して限界まで横方向にスライドすることにより、「カチッ」という係止音が発せられるように構成されている。この係止音は、図１３に示すように、吸込口本体５２の第１筐体部５２ａ1の底部から外部下方に突出・引っ込み可能に設けられた凸部５２ａ12が、装着ユニット５１の装着凹部５１ｚに設けられた係合凹部５１ｚ1に係止することにより発せられる。この係止音により、ユーザーは、装着ユニット５１を吸込口本体５２に確実に装着できたことを認識することができる。 In addition, by sliding the suction inlet body 52 laterally with respect to the mounting unit 51 to the limit, a locking sound “click” is generated. As shown in FIG. 13, the locking sound is generated when the mounting portion 51 is mounted by the convex portion 52 a 12 provided so as to protrude and retract outward from the bottom of the first housing portion 52 a 1 of the suction port body 52. It is emitted by engaging with an engaging recess 51z 1 provided in the recess 51z. From this locking sound, the user can recognize that the mounting unit 51 has been securely mounted to the suction port body 52.
　この場合、例えば、凸部５２ａ12は下方の先端に丸みを有する弾丸形に形成され、図示しない弾発部材にて下方へ弾発的に付勢される。また、係合凹部５１ｚ1は、装着凹部５１ｚの底面に形成された突起部５１ｚ2の丸みを有する頂部に形成された凹みとすることができる。このようにすれば、凸部５２ａ12が突起部５１ｚ2の丸み部分を乗り越えて係合凹部５１ｚ1に係止することができ、かつ係止の際に前記係止音が発せられやすくなる。 In this case, for example, the convex portion 52a 12 is formed in a bullet shape having a roundness at the lower end, and is elastically biased downward by a not-shown bullet member. Further, the engagement recess 51z 1 can be a recess formed on the top of the projection 51z 2 that is rounded on the bottom surface of the mounting recess 51z. Thus, it is the convex portion 52a 12 is engaged with the engaging recess 51z 1 overcame rounded portion of the projections 51z 2, and the engaging sound stop tends emitted during locking.
　吸込口本体５２を装着ユニット５１に対して限界まで横方向にスライドして装着した後、装着ユニット５１の装着凹部５１ｚにおける吸込口本体５２の第１筐体部５２ａ1の左側のスペースにロック部材５１ａ3を嵌め込む。これにより、吸込口本体５２に装着された装着ユニット５１が固定される。 After the suction port body 52 is slid laterally to the limit with respect to the mounting unit 51 and mounted, the lock member is placed in the space on the left side of the first housing portion 52a 1 of the suction port body 52 in the mounting recess 51z of the mounting unit 51. 51a 3 is inserted. Thereby, the mounting unit 51 mounted on the suction port body 52 is fixed.
　このとき、図１４（Ａ）と図１４（Ｂ）に示すように、吸込口本体５２の第１筐体部５２ａ1の左側部分に設けられた前記ロック検知部５２ａｘに対してロック部材５１ａ3が作用する、例えば、ロック部材５１ａ3がロック検知部５２ａｘのスイッチ部をＯＮすることによって、ロック検知部５２ａｘがロック検知信号を出力する。また、ロック部材５１ａ3を取り外すことにより、ロック検知部５２ａｘのスイッチ部がＯＦＦとなって、ロック検知部５２ａｘからのロック検知信号の出力が停止する。 At this time, as shown in FIGS. 14 (A) and 14 (B), the lock member 51a 3 with respect to the lock detection part 52ax provided in the left side portion of the first housing part 52a 1 of the suction inlet main body 52. For example, when the lock member 51a 3 turns on the switch part of the lock detection part 52ax, the lock detection part 52ax outputs a lock detection signal. Further, by removing the lock member 51a 3 , the switch part of the lock detection part 52ax is turned off, and the output of the lock detection signal from the lock detection part 52ax is stopped.
　このロック検知信号は、例えば、掃除機本体２内に設けられた制御部に入力され、そのロック検知信号に基づいて制御部はモータＭの駆動を制御する。つまり、吸込口本体５２に装着ユニット５１が適切に装着され固定されると、ロック検知信号が制御部に入力される。 The lock detection signal is input to, for example, a control unit provided in the cleaner body 2, and the control unit controls driving of the motor M based on the lock detection signal. That is, when the mounting unit 51 is properly mounted and fixed to the suction port body 52, a lock detection signal is input to the control unit.
　吸込口本体５２に床面清掃用の装着ユニット５１が装着されてなる吸込口ユニット５を備えた電気掃除機１によれば、前記のように吸込口ユニット５を床面上に載置することによって吸込可能状態検知部５２ａ3の車輪５２ａ32が上がって吸込可能状態検知信号が出力され、その吸込可能状態検知信が制御部に入力される。 According to the vacuum cleaner 1 having the suction port unit 5 in which the floor cleaning mounting unit 51 is mounted on the suction port body 52, the suction port unit 5 is placed on the floor as described above. wheels 52a 32 of the suction state detecting portion 52a 3 is suction state detection signal is output up, the suction state detection signal is input to the control unit by.
　ロック検知信号と吸込可能状態検知信号の両方が制御部に入力されることによって、吸込口ユニット５のモータＭは駆動可能状態となる。よって、ハンドル４ａの操作部４ｂを操作して運転モードにすると、掃除機本体２内の電動送風機が駆動すると共に、回転ブラシ部５１ｂ1が回転して床面清掃を行うことができる。 When both the lock detection signal and the suckable state detection signal are input to the control unit, the motor M of the suction port unit 5 is in a drivable state. Therefore, when the operation part 4b of the handle 4a is operated to enter the operation mode, the electric blower in the cleaner body 2 is driven and the rotating brush part 51b 1 is rotated to perform floor cleaning.
　実施形態１の吸込口ユニット５によれば、吸込口本体５２に装着ユニット５１が不適切に装着された状態のままモータＭが駆動して回転ブラシ部５１ｂ1が回転し、それによってモータＭ、駆動ギヤ部５２ａ2、ギヤ部５１ｂ28等の部品が損傷するという不具合を防止できると共に、吸込口ユニット５が床面上に載置されてから回転ブラシ部５１ｂ1が回転するという安全性に配慮することができる。 According to the suction port unit 5 of the first embodiment, the motor M is driven and the rotating brush portion 51b 1 is rotated while the mounting unit 51 is improperly mounted on the suction port body 52, whereby the motor M, In addition to preventing problems such as damage to parts such as the drive gear 52a 2 and the gear 51b 28 , consideration is given to the safety that the rotary brush 51b 1 rotates after the suction port unit 5 is placed on the floor surface. can do.
　吸込口本体５２を装着ユニット５１に対して限界まで横方向にスライドして装着することにより、駆動ギヤ部５２ａ2の各歯５２ａ21が、回転力伝達機構部５１ｂ2のギヤ部５１ｂ28の各歯の間に嵌り込む。この際、駆動ギヤ部５２ａ2の各歯５２ａ21はその摺接面２ａ212がギヤ部５１ｂ28の各歯の被摺接面に摺接しながら噛合することができるため、駆動ギヤ部５２ａ2の各歯５２ａ21とギヤ部５１ｂ28の各歯が衝突しても各ギヤは回転して位置調整しながら噛合することができる。また、駆動ギヤ部５２ａ2の各歯５２ａ21の摺接面５２ａ212とギヤ部５１ｂ28の各歯の被摺接面はギヤ回転方向に対して垂直な面であるため、駆動ギヤ部５２ａ2の回転力をギヤ部５１ｂ28に効率よく伝達することができる。 By sliding the suction inlet main body 52 laterally with respect to the mounting unit 51 to the limit, each tooth 52a 21 of the drive gear portion 52a 2 is connected to each of the gear portions 51b 28 of the rotational force transmission mechanism portion 51b 2. Fit between teeth. At this time, since each tooth 52a 21 of the driving gear portion 52a 2 is that at the sliding surface 2a 212 meshes while sliding on the sliding surface of each tooth of the gear portion 51b 28, the driving gear portion 52a 2 Even if each tooth of the teeth 52a 21 and each tooth of the gear portion 51b 28 collides, the gears can be meshed while rotating and adjusting their positions. Further, since the sliding contact surface 52a 212 of each tooth 52a 21 of the driving gear portion 52a 2 and the sliding contact surface of each tooth of the gear portion 51b 28 are surfaces perpendicular to the gear rotation direction, the driving gear portion 52a 2. Can be efficiently transmitted to the gear portion 51b 28 .
　なお、吸込口本体５２と装着ユニット５１の分離は、装着の手順と逆に行えばよい。また、モータＭや吸込状態検知部５２ａ3、ロック検知部５２ａｘ等の電気部品は吸込口本体５２内に収められ、装着ユニット５１内に電気部品は全く収められていないため、図８に示すように装着ユニット５１を分解して各部品を水洗いすることができる。 The suction port body 52 and the mounting unit 51 may be separated from the mounting procedure. Further, since the electrical components such as the motor M, the suction state detection unit 52a 3 and the lock detection unit 52ax are housed in the suction port body 52 and no electrical components are housed in the mounting unit 51, as shown in FIG. The mounting unit 51 can be disassembled and each part can be washed with water.

　下ケース１０５１ａ1は、底壁１０５１ａ11と、底壁１０５１ａ11の外周に沿って連設された周囲壁１０５１ａ12とを有する。
　下ケース１０５１ａ1における集塵開口部１０５１ｘを有する前方部と、集塵開口部１０５１ｘよりも後方の後方部との間には、これらの領域を区画する区画壁１０５１ａ13が設けられている。これにより、下ケース１０５１ａ1における後方部には吸込口本体５２の第１筐体部５２ａが装着される装着凹部１０５１ｚが形成される。なお、装着凹部１０５１ｚの底壁１０５１ａ11には、実施形態１の装着ユニット５１が有する窓部５１ａ111に相当する開口部は形成されていない。 The lower case 1051a 1 has a bottom wall 1051a 11 and a peripheral wall 1051a 12 connected along the outer periphery of the bottom wall 1051a 11 .
A partition wall 1051a 13 for partitioning these regions is provided between the front portion having the dust collection opening 1051x in the lower case 1051a 1 and the rear portion behind the dust collection opening 1051x.

　ギヤ部１０５１ｃ1は、そのボス部が金属軸１０５１ｃ5に一体回転可能に取り付けられている。また、金属軸１０５１ｃ5には小さい第１プーリ１０５１ｃ8が固着されている。 The boss portion of the gear portion 1051c 1 is attached to the metal shaft 1051c 5 so as to be integrally rotatable. A small first pulley 1051c 8 is fixed to the metal shaft 1051c 5 .
　カム部１０５１ｃ2は筒状の軸部を有し、その軸部の一端が金属軸１０５１ｃ7に一体回転可能に取り付けられると共に、金属軸１０５１ｃ7に大きい第４プーリ１０５１ｃ11が固着されている。また、カム部１０５１ｃ2の軸部の他端にも金属軸が固着されており、この金属軸に軸受を介して実施形態１と同様の軸受部５１Ｂが取り付けられている。 Cam portion 1051C 2 has a cylindrical shaft portion, the integrally attached to rotatable at one end the metal shaft 1051C 7 of the shaft portion, a fourth pulley 1051C 11 large metal shaft 1051C 7 is fixed. Also, the other end of the shaft portion of the cam portion 1051C 2 is secured a metal shaft, it is mounted a similar bearing portion 51B in the first embodiment through the bearing to the metal shaft.
　また、中間の金属軸１０５１ｃ6には大きい第２プーリ１０５１ｃ9および小さい第３プーリ１０５１ｃ10が固着されている。そして、第１と第２プーリ１０５１ｃ8、１０５１ｃ9がベルト１９５１ｃ12にて張架され、第３と第４プーリ１０５１ｃ10、１０５１ｃ11が別のベルト１９５１ｃ13にて張架されている。 The second pulley 1051C 9 and a small third pulley 1051C 10 is fixed large in the middle of the metal shaft 1051c 6.

［寝具清掃用の装着ユニットの吸込口本体への装着］ [Mounting the mounting unit for bedding cleaning to the inlet]
　図１９（Ａ）は実施形態２における装着ユニットを吸込口本体に装着する前の状態、図１９（Ｂ）は装着後の状態を示す断面図であり、図２０は実施形態２における装着ユニットを吸込口本体に装着する状態を示す部分断面図である。 FIG. 19A is a state before the mounting unit according to the second embodiment is mounted on the suction port body, FIG. 19B is a cross-sectional view illustrating the state after mounting, and FIG. It is a fragmentary sectional view which shows the state with which a suction inlet main body is mounted | worn.
　吸込口本体５２に装着ユニット１０５１を装着する際は、実施形態１の場合と同様である。すなわち、装着ユニット１０５１の装着凹部１０５１ｚの上方に吸込口本体５２を移動させ、吸込口本体５２の第１筐体部５２ａ1を装着ユニット１０５１の装着凹部１０５１ｚに挿入する。そして、吸込口本体５２を右方向へスライド移動させることにより、吸込口本体５２の駆動ギヤ部５２ａ2が駆動力伝達機構１０５１ｃのギヤ部１０５１ｃ1と噛合する。 When the mounting unit 1051 is mounted on the suction port body 52, it is the same as in the first embodiment. That is, by moving the suction inlet main body 52 above the mounting recess 1051z of the mounting unit 1051, inserting the first housing portion 52a 1 of the suction inlet main body 52 to the mounting recess 1051z of the mounting unit 1051. Then, by sliding the suction port body 52 to the right, the drive gear portion 52a 2 of the suction port body 52 meshes with the gear portion 1051c 1 of the drive force transmission mechanism 1051c.
　このとき、図１９（Ａ）、図１９（Ｂ）および図２０に示すように、吸込可能状態検知部５２ａ3の車輪５２ａ32は、装着ユニット１０５１の装着凹部１０５１ｚの底壁１０５１ａ11上に乗る。よって、車輪５２ａ32は上がった状態であるため、吸込可能状態検知部５２ａ3から制御部に向かって吸込可能状態検知信号が出力される。 At this time, as shown in FIG. 19A, FIG. 19B, and FIG. 20, the wheel 52a 32 of the inhalable state detection unit 52a 3 gets on the bottom wall 1051a 11 of the mounting recess 1051z of the mounting unit 1051. . Therefore, since the wheels 52a 32 is in a state raised, suction state detection signal toward the suction state detection unit 52a 3 to the control unit is outputted.
　なお、仮に、実施形態１のように車輪５２ａ32が装着ユニット１０５１の下方外部に突出していたとすると、吸込口ユニット１００５を布団上に載置したときに吸込可能状態検知部５２ａ3の車輪５２ａ32が布団に埋没するおそれがある。そうすると、車輪５２ａ32が上昇せず、吸込可能状態検知部５２ａ3が布団を検知しないため、吸込可能状態検知部５２ａ3から制御部に向かって吸込可能状態検知信号が出力されなくなる。その場合、モータＭが駆動しないため叩き板１０５１ｂ1が揺動しないという不具合が生じるおそれがある。 Incidentally, if, performed when the wheel 52a 32 as Embodiment 1 is that protrude downward outside the mounting unit 1051, the wheel 52a of the suction state detection unit 52a 3 when the suction port unit 1005 is placed on the futon 32 May be buried in the futon. Then, without increasing the wheel 52a 32 is, the suction state detection unit 52a 3 because it does not detect the futon, suction state detection signal toward the control unit from the suction state detecting portion 52a 3 is not outputted. In that case, since the motor M is not driven, there is a possibility that the hitting plate 1051b 1 does not swing.
　また、実施形態１と同様に、下ケース１０５１ａ1の複数の係止凸部１０５１ａ131が吸込口本体５２の複数の係止溝部５２ａ5に係止する。また、吸込口本体５２を装着ユニット５１に対して限界まで横方向にスライドすることにより、「カチッ」という係止音が発せられる。すなわち、寝具清掃用の装着ユニット１０５１にも、実施形態１と同様に、係合凹部１０５１ｚ1が設けられている。 Similarly to the first embodiment, the plurality of locking projections 1051 a 131 of the lower case 1051 a 1 are locked to the plurality of locking grooves 52 a 5 of the suction port body 52. Further, when the suction port body 52 is slid laterally to the limit with respect to the mounting unit 51, a locking sound “click” is generated. That is, even in the mounting unit 1051 for bedding cleaning, as in Embodiment 1, is provided engaging recess 1051Z 1.
　吸込口本体５２を装着ユニット１０５１に対して限界まで横方向にスライドして装着した後、実施形態１と同様に、装着ユニット１０５１の装着凹部１０５１ｚにおける吸込口本体５２の第１筐体部５２ａ1の左側のスペースにロック部材１０５１ａ3を嵌め込む。これにより、吸込口本体５２に装着された装着ユニット１０５１が固定される（図１２（Ａ）、図１２（Ｂ）参照）。 After the suction port body 52 is slid laterally with respect to the mounting unit 1051 and mounted, the first housing portion 52a 1 of the suction port body 52 in the mounting recess 1051z of the mounting unit 1051 is mounted as in the first embodiment. The lock member 1051a 3 is fitted into the left space. Thereby, the mounting unit 1051 mounted on the suction port body 52 is fixed (see FIGS. 12A and 12B).
　このときも、実施形態１と同様に、吸込口本体５２のロック検知部５２ａｘに対してロック部材１０５１ａ3がロック検知部５２ａｘのスイッチ部をＯＮすることによって、ロック検知部５２ａｘがロック検知信号を出力する。また、ロック部材１０５１ａ3を取り外すことにより、ロック検知部５２ａｘのスイッチ部がＯＦＦとなって、ロック検知部５２ａｘからのロック検知信号の出力が停止する。 In this case, similarly to Embodiment 1, by the locking member 1051a 3 is turned ON the switch portion of the lock detection unit 52ax the lock detecting portion 52ax of the suction port main body 52, the lock detection unit 52ax is a lock detection signal Output. Further, by removing the lock member 1051a 3 , the switch unit of the lock detection unit 52ax is turned off, and the output of the lock detection signal from the lock detection unit 52ax is stopped.
　そして、このロック検知信号は、例えば、掃除機本体２内に設けられた制御部に入力され、そのロック検知信号に基づいて制御部はモータＭの駆動を制御する。つまり、吸込口本体５２に装着ユニット１０５１が適切に装着され固定されると、ロック検知信号が制御部に入力される。 The lock detection signal is input to, for example, a control unit provided in the cleaner body 2, and the control unit controls driving of the motor M based on the lock detection signal. That is, when the mounting unit 1051 is properly mounted and fixed to the suction port body 52, a lock detection signal is input to the control unit.
　このように、吸込口本体５２に寝具清掃用の装着ユニット１０５１が装着されてなる吸込口ユニット１００５を備えた電気掃除機によれば、吸込口本体５２に装着ユニット１０５１が適切に装着され固定されると、吸込可能状態検知信号およびロック検知信号が制御部に入力される。 As described above, according to the vacuum cleaner including the suction port unit 1005 in which the bedding cleaning mounting unit 1051 is mounted on the suction port body 52, the mounting unit 1051 is appropriately mounted and fixed on the suction port body 52. Then, the suckable state detection signal and the lock detection signal are input to the control unit.
　ロック検知信号と吸込可能状態検知信号の両方が制御部に入力されることによって、吸込口ユニット５のモータＭは駆動可能状態となる。よって、ハンドル４ａの操作部４ｂを操作して運転モードにすると、掃除機本体２内の電動送風機が駆動して吸込口ユニット１００５による吸引が開始し、かつ叩き板１０５１ｂ1が揺動して寝具清掃を行うことができる。 When both the lock detection signal and the suckable state detection signal are input to the control unit, the motor M of the suction port unit 5 is in a drivable state. Therefore, when the operation mode by operating the operation unit 4b of the handle 4a, and starts suction by the suction port unit 1005 electric blower in the vacuum cleaner body 2 is driven, and with beating plate 1051b 1 is swung bedding Cleaning can be performed.
　実施形態２の吸込口ユニット１００５によれば、吸込口本体５２に装着ユニット１０５１が不適切に装着された状態のままモータＭが駆動して叩き板１０５１ｂ1が揺動し、それによってモータＭ、駆動ギヤ部５２ａ2、ギヤ部１０５１ｃ1等の部品が損傷するという不具合を防止できると共に、吸込可能状態検知部５２ａ3が装着ユニット１０５１を検知して確実に叩き板１０５１ｂ1を揺動させることができる。 According to the suction port unit 1005 of the second embodiment, the motor M is driven while the mounting unit 1051 is improperly mounted on the suction port main body 52 and the hitting plate 1051b 1 is swung, whereby the motor M, The trouble that parts such as the drive gear portion 52a 2 and the gear portion 1051c 1 are damaged can be prevented, and the suctionable state detecting portion 52a 3 can detect the mounting unit 1051 and surely swing the hitting plate 1051b 1. it can.
　このとき、実施形態１と同様に、吸込口本体５２の吸込口５２ａ1に流入する空気の流れによって、第１筐体部５２ａ内に収納されたモータＭ、吸込可能状態検知部５２ａ3、ロック検出部５２ａｘ等の電気部品が冷却される（図５参照）。 At this time, as in the first embodiment, the motor M housed in the first housing 52a, the suckable state detection unit 52a 3 , the lock by the flow of air flowing into the suction port 52a 1 of the suction port body 52 Electrical components such as the detection unit 52ax are cooled (see FIG. 5).
　なお、吸込口本体５２と装着ユニット１０５１の分離は、装着の手順と逆に行えばよい。また、モータＭや吸込状態検知部５２ａ3、ロック検知部５２ａｘ等の電気部品は吸込口本体５２内に収められ、装着ユニット１０５１内に電気部品は全く収められていないため、図１８のように装着ユニット１０５１を分解して各部品を水洗いすることができる。 The suction port body 52 and the mounting unit 1051 may be separated from the mounting procedure. Further, since the electrical components such as the motor M, the suction state detection unit 52a 3 and the lock detection unit 52ax are accommodated in the suction port main body 52 and no electrical components are accommodated in the mounting unit 1051, as shown in FIG. The mounting unit 1051 can be disassembled and each component can be washed with water.

　さらに、駆動力伝達機構収納室２０５２ｍ2の側壁には吸気孔２０５２ｍ21が形成されると共に、後部筐体２０５２ａ11と前部筐体２０５２ａ12の間の隔壁には排気孔２０５２ｍ11が形成されている。これにより、モータ収納室２０５２ｍ1と後部筐体２０５２ａ11の内部とは排気孔２０５２ｍ11を介して連通している。 Further, an intake hole 2052m 21 is formed in the side wall of the driving force transmission mechanism storage chamber 2052m 2 , and an exhaust hole 2052m 11 is formed in the partition wall between the rear casing 2052a 11 and the front casing 2052a 12. Yes. Thus, the interior of the motor housing chamber 2052M 1 and the rear housing 2052a 11 communicates via the exhaust hole 2052m 11.
　このように構成された吸込口本体２０５２に装着ユニット２０５１を図２２に示すように装着すると、吸込口本体２０５２の大ギヤ２０５２ｂ2と装着ユニット２０５１の回転ブラシギヤ２０５１ｂ3とが噛合する。これにより、モータＭの駆動力は、小ギヤ２０５２ｂ1、大ギヤ２０５２ｂ2および回転ブラシギヤ２０５１ｂ3を介して回転ブラシ部２０５１ｂ2に伝達され、それによって回転ブラシ部２０５１ｂ2が回転する。この場合、駆動ギアとしての小ギヤ２０５２ｂ1が大ギヤ２０５２ｂ2を介して回転ブラシギヤ２０５１ｂ3と噛合するように構成されている。 With this mount the mounting unit 2051 to configured suction port body 2052 as shown in FIG. 22, a large gear 2052B 2 of the suction inlet main body 2052 and the rotation brush gear 2051b 3 of the mounting unit 2051 is engaged. Thereby, the driving force of the motor M is transmitted to the rotating brush portion 2051b 2 via the small gear 2052b 1 , the large gear 2052b 2 and the rotating brush gear 2051b 3 , thereby rotating the rotating brush portion 2051b 2 . In this case, the small gear 2052b 1 as the drive gear is configured to mesh with the rotating brush gear 2051b 3 via the large gear 2052b 2 .
　実施形態３の吸込口ユニット２００５によれば、掃除機本体が駆動して吸引することにより、回転ブラシ部２０５１ｂ2が回転しながら集塵開口部２０５１ｘから塵埃を含む空気が吸引される。このとき、吸込口本体２０５２の吸込口２０５２ａ1に空気が流入することによりモータ収納室２０５２ｍ1内の空気が排気孔２０５２ｍ11から後部筐体２０５２ａ11内に引き込まれる。すると、モータ収納室２０５２ｍ1が負圧になるため、外部の空気が吸気孔２０５２ｍ21を通って駆動力伝達機構収納室２０５２ｍ2内に流入し、モータＭ内を通ってモータ収納室２０５２ｍ1に流入するという気流が生じる。これにより、モータＭが冷却される。 According to the suction port unit 2005 of Embodiment 3, by the cleaner main body is sucked by driving and rotating the brush portion 2051b 2 air containing dust from the dust collecting opening 2051x while rotating is sucked. At this time, the air motor housing chamber 2052M 1 is drawn into the exhaust hole 2052M 11 rear housing 2052a in 11 by the air flowing into the suction port 2052a 1 of the suction port main body 2052. Then, since the motor storage chamber 2052m 1 has a negative pressure, external air flows into the driving force transmission mechanism storage chamber 2052m 2 through the intake hole 2052m 21 , passes through the motor M, and enters the motor storage chamber 2052m 1 . An airflow that flows in is generated. Thereby, the motor M is cooled.
　なお、吸込口本体２０５２と装着ユニット２０５１の分離は、装着の手順と逆に行えばよい。また、モータＭ等の電気部品は吸込口本体２０５２内に収められ、装着ユニット２０５１内に電気部品は全く収められていないため、装着ユニット２０５１を分解して各部品を水洗いすることができる。 In addition, what is necessary is just to perform separation of the suction inlet main body 2052 and the mounting | wearing unit 2051 reverse to the procedure of mounting | wearing. In addition, since the electrical components such as the motor M are accommodated in the suction inlet main body 2052 and no electrical components are accommodated in the mounting unit 2051, the mounting unit 2051 can be disassembled and each component can be washed with water.
　また、実施形態３の吸込口本体２０５２に装着可能な寝具清掃用装着ユニットを作製することにより、共通の吸込口本体２０５２を用いて床面清掃用の吸込口ユニットと寝具清掃用の吸込口ユニットを低コストにて得ることができる。この場合の寝具清掃用装着ユニットは、実施形態２の叩き板１０５１ｂと駆動力伝達機構１０５１ｃの駆動原理を応用して作製することができる（図１８参照）。 Further, by preparing a bedding cleaning mounting unit that can be mounted on the suction port body 2052 of Embodiment 3, a floor surface suction port unit and a bedding cleaning suction unit using the common suction port body 2052 Can be obtained at low cost. The bedding cleaning mounting unit in this case can be manufactured by applying the driving principle of the hitting plate 1051b and the driving force transmission mechanism 1051c of the second embodiment (see FIG. 18).

And a motor for driving
The housing includes a motor storage chamber for storing the motor, an intake hole through which external air can be sucked into the motor storage chamber, and an exhaust hole through which air passing through the motor storage chamber can be exhausted to the suction port side. And have.
　本発明の電気掃除機の吸込口本体は、次のように構成されてもよく、それらが適宜組み合わされてもよい。
（I）前記筐体は、一方向に長い形状で形成された前記吸込口を有する第１筐体部と、この第１筐体部の長手方向と直交する方向に形成されて電気掃除機の掃除機本体に接続される第２筐体部とを備え、
　前記第２筐体部の内部は前記吸込口と連通する通風路であり、
　前記第１筐体部において、前記吸込口の長手方向一端側に前記モータ収納室が設けられ、前記一端側に前記吸気孔が形成され、前記通風路側に前記排気孔が形成されてもよい。 The suction inlet main body of the vacuum cleaner of this invention may be comprised as follows, and may be combined suitably.
(I) The said housing | casing is formed in the direction orthogonal to the longitudinal direction of this 1st housing | casing part with the 1st housing | casing part formed in the shape long in one direction, and the vacuum cleaner, A second housing connected to the vacuum cleaner body,
The inside of the second housing part is a ventilation path communicating with the suction port,
In the first housing part, the motor storage chamber may be provided on one end side in the longitudinal direction of the suction port, the intake hole may be formed on the one end side, and the exhaust hole may be formed on the ventilation path side.
　このようにすれば、吸込口本体をＴ形に形成し、第１筐体部の長手方向一端側にモータを配置することができるため、このモータの駆動力を装着ユニットの回動清掃部材に伝達する駆動力伝達機構を装着ユニットにおける回動清掃部材の一端側に配置することが可能となる。
　これにより、モータ収納室、吸気孔および排気孔を吸込口本体に容易に配置できる構造となる。また、これに加え、吸込口本体の左右中間に配置する吸込口付近に吸い込みの邪魔となる大きい部品（駆動力伝達機構）が配置されることがなくなるため、吸込口ユニットの吸引性能を低下させることがない。 In this way, the suction port body can be formed in a T shape, and the motor can be arranged on one end side in the longitudinal direction of the first housing portion. Therefore, the driving force of this motor is applied to the rotational cleaning member of the mounting unit. The driving force transmission mechanism for transmitting can be arranged on one end side of the rotational cleaning member in the mounting unit.
Thereby, it becomes a structure which can arrange | position a motor storage chamber, an intake hole, and an exhaust hole easily to a suction inlet main body. In addition to this, a large part (driving force transmission mechanism) that obstructs suction is not disposed near the suction port disposed in the middle of the left and right of the suction port body, so that the suction performance of the suction port unit is lowered. There is nothing.
　また、第１筐体部の左右中間に駆動力伝達機構を配置すると、駆動力伝達機構および回動清掃部材の構成が複雑化することに加え、第１筐体部と第２筐体部との接続部分が大きくなって吸込口本体の見栄えが悪化する。これに対し、第１筐体部の一端側に駆動力伝達機構を配置することで、駆動力伝達機構および回動清掃部材の構成を簡素化することできると共に、吸込口本体の見栄えが向上するメリットも得られる。 Further, when the driving force transmission mechanism is arranged in the middle of the left and right of the first housing part, the configurations of the driving force transmission mechanism and the rotation cleaning member become complicated, and the first housing part and the second housing part The connecting portion of the inlet becomes larger and the appearance of the suction port body deteriorates. On the other hand, by disposing the driving force transmission mechanism on one end side of the first housing portion, the configuration of the driving force transmission mechanism and the rotational cleaning member can be simplified, and the appearance of the suction port body is improved. There are also benefits.
（II）前記モータは、その出力軸の先端が前記吸気孔側に配置され、前記出力軸の基端が前記排気孔側に配置されてもよい。
　このようにすれば、第１筐体部の一端側にモータの出力軸および駆動力伝達機構を配置し、第１筐体部の一端側に吸気孔を配置し、第１筐体部の長手方向中間位置の吸込口側に排気孔を配置した合理的な構造となる。 (II) The motor may have a front end of the output shaft disposed on the intake hole side and a proximal end of the output shaft disposed on the exhaust hole side.
According to this configuration, the motor output shaft and the driving force transmission mechanism are arranged on one end side of the first casing unit, the air intake holes are arranged on one end side of the first casing unit, and the length of the first casing unit is set. It is a rational structure in which an exhaust hole is arranged on the suction port side in the middle direction.
（IV）前記吸込口は、清掃面に対して略垂直面を成して構成されてもよい。
　このようにすれば、第１筐体部の吸込口と接続される装着ユニット側の開口部と接続される通風路の投影面積が少なくなることから第１筐体部のコンパクト化が図れる。 (IV) The suction port may be configured to form a substantially vertical surface with respect to the cleaning surface.
By doing so, the projection area of the ventilation path connected to the opening on the mounting unit connected to the suction port of the first casing is reduced, so that the first casing can be made compact.
　また、本発明の別の観点によれば、前記吸込口本体と、この吸込口本体に装着される清掃用の装着ユニットとを備え、
　前記装着ユニットが、回転可能な回転ブラシを有する床面清掃用装着ユニット、または揺動可能な叩き板を有する寝具清掃用装着ユニットである電気掃除機の吸込口ユニットが提供される。 Further, according to another aspect of the present invention, the suction port body, and a cleaning mounting unit mounted on the suction port body,
There is provided a suction port unit of a vacuum cleaner, wherein the mounting unit is a floor surface cleaning mounting unit having a rotatable rotating brush or a bedding cleaning mounting unit having a swinging hitting plate.
