A DC constant voltage circuit for maintaining the voltage between the rectifier circuit and the control circuit.

本発明によれば、駆動用充電式電池の温度上昇を抑えることができる。   According to the present invention, the temperature rise of the rechargeable battery for driving can be suppressed.

以下、本発明の実施形態について、図面を引用して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図1、2に示すように掃除機本体1には、掃除機本体1の前側に接続された可撓性を有するホース2と、ホース2の掃除機本体1との接続部に設けられた前ハンドル3と、前ハンドル3に備わる支持部4に取り付けられた延長管5と、延長管5の先端に備わる吸口6が取り付けられる。充電台7には、掃除機本体1を立てた状態で収納される。またこの状態で掃除機本体1に備わる駆動用充電式電池への充電が行われる。充電台7の上面には、充電供給接続台8が備わる。この充電供給接続台8については、後でさらに詳しく述べる。   As shown in FIGS. 1 and 2, the vacuum cleaner main body 1 includes a flexible hose 2 connected to the front side of the vacuum cleaner main body 1 and a front portion provided at a connection portion between the hose 2 and the vacuum cleaner main body 1. A handle 3, an extension pipe 5 attached to a support portion 4 provided in the front handle 3, and a suction port 6 provided at the tip of the extension pipe 5 are attached. The charging stand 7 is stored with the vacuum cleaner body 1 in an upright state. In this state, the rechargeable battery for driving provided in the cleaner body 1 is charged. A charging supply connection base 8 is provided on the upper surface of the charging base 7. The charge supply connection base 8 will be described in more detail later.

掃除機本体1は、図4、5、6に示すような構成になっている。   The cleaner body 1 is configured as shown in FIGS.

掃除機本体1の外郭は、合成樹脂の下ケース9、合成樹脂の上ケース10、合成樹脂の前側外カバー20、合成樹脂の後側外カバー21で形成される。上.下ケース9,10は断面がU字状で前後方向に延びた形状をしている。上.下ケース9,10を上下に重ね合わせることにより、内部に空洞が形成される。前側外カバー20の内側には、内側カバー22が取り付けられる。掃除機本体1の後側両側部には走行用の後車輪23が、前側低部には走行用の前車輪24が備わる。   The outer body of the vacuum cleaner body 1 is formed by a synthetic resin lower case 9, a synthetic resin upper case 10, a synthetic resin front outer cover 20, and a synthetic resin rear outer cover 21. The upper and lower cases 9, 10 have a U-shaped cross section and have a shape extending in the front-rear direction. By overlapping the upper and lower cases 9 and 10 vertically, a cavity is formed inside. An inner cover 22 is attached to the inner side of the front outer cover 20. A rear wheel 23 for traveling is provided on both sides of the rear side of the vacuum cleaner body 1, and a front wheel 24 for traveling is provided on the lower front side.

掃除機本体1の内部には、集塵ケース25、電動送風機26等が備わる。電動送風機26は電動送風機収納室27に収納される。集塵ケース25は電動送風機26の前側に配置される。集塵ケース25の内側には集塵袋28が取り外し自在に置かれる。掃除機の制御回路が載置された制御基盤29は集塵ケース25の上側に取り付けられる。   Inside the vacuum cleaner main body 1, a dust collection case 25, an electric blower 26, and the like are provided. The electric blower 26 is stored in the electric blower storage chamber 27. The dust collection case 25 is disposed on the front side of the electric blower 26. A dust collection bag 28 is detachably placed inside the dust collection case 25. The control base 29 on which the control circuit of the vacuum cleaner is mounted is attached to the upper side of the dust collecting case 25.

掃除機本体1の内部に設けられる電動送風機収納室27は、横置きに配置される円筒部40と、該円筒部40の後端に設けられる縦の仕切壁41とで形成される。円筒部40と上.下ケース10,9の外壁との間には環状の排気流路が形成される。円筒部40の上部に設けた通り抜け孔42で、円筒部40の内側と環状排気流路が連通する。この環状排気流路の底部には細塵フィルタ43が収納されるフイルタ室45が設けられる。フィルタ室45は仕切壁41の後側に設けられる排気室46に連通孔47をもって連通する。排気室46は後側外カバー21の上側に設けた外部排気穴48によって外気に連通するように構成される。   The electric blower storage chamber 27 provided inside the cleaner body 1 is formed by a cylindrical portion 40 that is disposed horizontally and a vertical partition wall 41 that is provided at the rear end of the cylindrical portion 40. An annular exhaust passage is formed between the cylindrical portion 40 and the outer walls of the upper and lower cases 10 and 9. The inside of the cylindrical portion 40 and the annular exhaust passage communicate with each other through a through hole 42 provided in the upper portion of the cylindrical portion 40. A filter chamber 45 in which the fine dust filter 43 is accommodated is provided at the bottom of the annular exhaust passage. The filter chamber 45 communicates with an exhaust chamber 46 provided on the rear side of the partition wall 41 through a communication hole 47. The exhaust chamber 46 is configured to communicate with the outside air through an external exhaust hole 48 provided on the upper side of the rear outer cover 21.

電動送風機23は、ファン部60と電動機61を有する。ファン部60に備わるファン62は電動機61の回転軸に固定支持されている。ファン部60の外周はファンパッキング63を介して電動送風機収納室27に支持される。電動機61のハウジング64に設けた軸受部65は軸受パッキング66を介して仕切壁41に支持される。ファンパッキング63と軸受パッキング66は気密シールと弾性支持の機能が備わる。   The electric blower 23 includes a fan unit 60 and an electric motor 61. A fan 62 provided in the fan unit 60 is fixedly supported on the rotating shaft of the electric motor 61. The outer periphery of the fan unit 60 is supported by the electric blower storage chamber 27 via the fan packing 63. A bearing portion 65 provided in the housing 64 of the electric motor 61 is supported by the partition wall 41 via a bearing packing 66. The fan packing 63 and the bearing packing 66 have an airtight seal and an elastic support function.

後側外カバー21には、上部内側に電気部品が配置収納され、下側に電池収納部70が設けられる。電池収納部70は掃除機本体1の内方に向かって凹み、かつ横方向に長く延在する横溝状の形をしている。電池収納部70は排気室46を流れる排気を遮る壁をもって形成されている。この電池収納部70は合成樹脂で形成され、かつ後側外カバー21と一体に形成されている。後側外カバー21とは別体に形成した電池収納部70を備えることも可能であるが、一体の方が生産性の面で有利である。また、電池収納部40は下ケース9と一体に形成することも可能である。   The rear outer cover 21 has an electrical component disposed and housed inside the upper portion, and a battery housing portion 70 provided on the lower side. The battery housing portion 70 is recessed toward the inside of the cleaner body 1 and has a lateral groove shape extending long in the lateral direction. The battery housing part 70 is formed with a wall that blocks the exhaust flowing through the exhaust chamber 46. The battery housing part 70 is made of synthetic resin and is formed integrally with the rear outer cover 21. Although it is possible to provide a battery housing part 70 formed separately from the rear outer cover 21, the integrated one is more advantageous in terms of productivity. Further, the battery housing portion 40 can be formed integrally with the lower case 9.

駆動用充電式電池71は電池収納部70に収納される。この棒体のような形をしている駆動用充電式電池71は、NiCd電池あるいはニッケル水素やリチウムイオン電池といった電池を使用する。電池収納部70は前述のように排気室46を流れる排気を遮る壁をもって形成されているので、電動送風機23から排気される高温の排気で駆動式電池71が加熱されることが抑えられる。また電池収納部70の内側面には断熱材72が貼付けられているので加熱抑制はさらに向上する。断熱材72は電池収納部70の外側面に設けても良い。   The driving rechargeable battery 71 is stored in the battery storage unit 70. The drive rechargeable battery 71 shaped like this rod uses a NiCd battery or a battery such as a nickel metal hydride or lithium ion battery. Since the battery housing part 70 is formed with a wall that blocks the exhaust flowing through the exhaust chamber 46 as described above, it is possible to suppress the driving battery 71 from being heated by the high-temperature exhaust exhausted from the electric blower 23. Moreover, since the heat insulating material 72 is affixed on the inner surface of the battery storage part 70, heating suppression is further improved. The heat insulating material 72 may be provided on the outer surface of the battery storage unit 70.

電池収納部70は、出し入れ口73が設けられる。この出し入れ口73には電池蓋74が着脱自在に備わる。電池蓋74の下部に設けられている係止部75は出し入れ口73の下側口縁部に係止される。電池蓋74の上部に設けた二つの係止爪76は出し入れ口の上側口縁部に係止される。電池蓋74は係止部75と係止爪76で取り付けられる。この電池蓋74で、駆動用充電式電池71の電池収納部70からの脱落は抑えられる。電池収納部70の底部が下側口縁部より上げられているので、電池蓋74をしない場合でも駆動用充電式電池71は簡単に脱落しないのである。   The battery storage unit 70 is provided with a slot 73. A battery lid 74 is detachably attached to the access port 73. The locking portion 75 provided at the lower portion of the battery lid 74 is locked to the lower opening edge of the loading / unloading port 73. Two locking claws 76 provided on the upper part of the battery lid 74 are locked to the upper opening edge of the loading / unloading port. The battery lid 74 is attached by a locking portion 75 and a locking claw 76. With this battery lid 74, dropping of the driving rechargeable battery 71 from the battery housing portion 70 is suppressed. Since the bottom part of the battery housing part 70 is raised from the lower opening edge part, the driving rechargeable battery 71 does not easily fall off even when the battery cover 74 is not used.

次に掃除機の電気回路について、図11,12に沿い述べる。   Next, the electric circuit of the vacuum cleaner will be described with reference to FIGS.

交流電源に接続するプラグ80は、ヒューズ81を介し交流/直流の切替スイッチ82の交流受側端子に接続される。充電受接続端子84は、前記充電台7の充電回路83の充電供給接続端子に接続される。充電受接続端子84は一方がダイオード85,ヒューズ86を、他方が充電用スイッチ87を介して交流/直流の切替スイッチ82の直流受側端子に接続される。交流/直流の切替スイッチ82の出力側端子は、交流側と直流側を選択切り替えできるようになっている。   The plug 80 connected to the AC power source is connected to the AC receiving side terminal of the AC / DC changeover switch 82 via the fuse 81. The charge receiving connection terminal 84 is connected to the charge supply connection terminal of the charging circuit 83 of the charging stand 7. One of the charge receiving connection terminals 84 is connected to the DC receiving side terminal of the AC / DC changeover switch 82 via the diode 85 and the fuse 86 and the other via the charging switch 87. The output side terminal of the AC / DC switching switch 82 can be selectively switched between the AC side and the DC side.

充電受接続端子84は、本来、2本で済むが、3本になっている。追加された充電受接続端子84は駆動用充電式電池71の内部に備わるサーミスタ88を充電回路83と接続するものである。サーミスタ88は充電時に駆動用充電式電池71が異常に温度上昇するのを抑える温度検知手段になるもので、充電中に駆動用充電式電池71が所定の温度を越えたら充電を止めるようにしている。   The number of charge receiving connection terminals 84 is originally two, but is three. The added charge receiving connection terminal 84 is for connecting the thermistor 88 provided in the driving rechargeable battery 71 to the charging circuit 83. The thermistor 88 serves as a temperature detecting means for suppressing the temperature of the driving rechargeable battery 71 from rising abnormally during charging. When the driving rechargeable battery 71 exceeds a predetermined temperature during charging, charging is stopped. Yes.

駆動用充電式電池71は、充電受接続端子側にコネクターを介して接続される。このコネクターは、充電受接続端子側の雌コネクター100と駆動用充電式電池71側の雄コネクター101が備わる。駆動用充電式電池71のプラス電極側はコネクターを介してダイオード85のプラス端子側に接続される。駆動用充電式電池71のマイナス電極側はコネクターを介して充電用スイッチ87の充電受接続端子側に接続される。   The drive rechargeable battery 71 is connected to the charge receiving connection terminal side via a connector. This connector includes a female connector 100 on the charge receiving connection terminal side and a male connector 101 on the drive rechargeable battery 71 side. The positive electrode side of the driving rechargeable battery 71 is connected to the positive terminal side of the diode 85 via a connector. The negative electrode side of the driving rechargeable battery 71 is connected to the charge receiving connection terminal side of the charging switch 87 via a connector.

駆動用充電式電池71のサーミスタ88は、一端がマイナス電極側に接続され、他端はコネクター、充電受接続端子、充電供給接続端子を介して充電回路の(A)点に接続される。この(A)点と充電回路83のプラス電極側間に固定抵抗102が接続される。このようにサーミスタ83と固定抵抗102は直列になっているので、駆動用充電式電池71の温度上昇に伴うサーミスタ83の抵抗増加で(A)点の電位が低下する。所定の電位以下になったら充電回路83の充電を止めるようにしている。充電停止温度は約60℃に設定している。また放電中においても同様に所定温度以上で停止するように構成すれば信頼性が向上する。   One end of the thermistor 88 of the driving rechargeable battery 71 is connected to the negative electrode side, and the other end is connected to a point (A) of the charging circuit via a connector, a charge receiving connection terminal, and a charge supply connection terminal. A fixed resistor 102 is connected between the point (A) and the positive electrode side of the charging circuit 83. Thus, since the thermistor 83 and the fixed resistor 102 are in series, the potential at the point (A) is lowered due to an increase in resistance of the thermistor 83 accompanying a rise in temperature of the driving rechargeable battery 71. The charging of the charging circuit 83 is stopped when the potential becomes lower than a predetermined potential. The charge stop temperature is set to about 60 ° C. Similarly, reliability can be improved if the apparatus is configured to stop at a predetermined temperature or higher during discharge.

交流/直流の切替スイッチ82の出力側端子側は、整流回路110、直流定電圧回路111を介してマイコン等の主なる制御回路112に接続される。また、その出力側端子側は電動機駆動回路113を介して電動機28に接続されている。   The output side terminal side of the AC / DC changeover switch 82 is connected to a main control circuit 112 such as a microcomputer via a rectifier circuit 110 and a DC constant voltage circuit 111. Further, the output side terminal side is connected to the electric motor 28 via the electric motor drive circuit 113.

整流回路110は、整流用ダイオード114、平滑用コンデンサー115を有する。直流定電圧回路111はトランジスター116、スイッチング回路117、コイル118、ダイオード119を有する。この直流定電圧回路111は、入力側の直流電圧が多様であっても5Vの定電圧を出力するようになっている。交流/直流の切替スイッチ82の出力側端子側で交流を選択したときは141の直流が、交流/直流の切替スイッチ82の出力側端子側で直流を選択したときは24Vの直流が供給されるが、いずれも直流定電圧回路111は制御回路112に5Vを出力するようになっている。   The rectifier circuit 110 includes a rectifier diode 114 and a smoothing capacitor 115. The DC constant voltage circuit 111 includes a transistor 116, a switching circuit 117, a coil 118, and a diode 119. The DC constant voltage circuit 111 outputs a constant voltage of 5V even if the DC voltage on the input side varies. When alternating current is selected on the output side terminal side of the alternating current / direct current switch 82, direct current 141 is supplied, and when direct current is selected on the output side terminal side of the alternating current / direct current switch 82, direct current 24V is supplied. However, in either case, the DC constant voltage circuit 111 outputs 5 V to the control circuit 112.

直流定電圧回路111の動作を簡単に説明する。トランジスター116をオンにする信号をベースに、スイッチング回路117から受けると、トランジスター116は通電しコイル118にエネルギーが蓄積される。エネルギーが蓄積されたら、スイッチング回路117からオフの信号を受けてトランジスター116はオフする。トランジスター116がオフになると、コイル118に蓄えられていたエネルギーがダイオード119を介して放出され、制御回路112に供給される。制御回路112に供給される電圧が常に5Vになるようにスイッチング回路117のスイッチングタイミングが仕組まれているのである。   The operation of the DC constant voltage circuit 111 will be briefly described. When receiving from the switching circuit 117 based on a signal for turning on the transistor 116, the transistor 116 is energized and energy is stored in the coil 118. When energy is stored, the transistor 116 is turned off in response to an off signal from the switching circuit 117. When the transistor 116 is turned off, the energy stored in the coil 118 is released through the diode 119 and supplied to the control circuit 112. The switching timing of the switching circuit 117 is set so that the voltage supplied to the control circuit 112 is always 5V.

電動機駆動回路113は、FLS130(スイッチング素子)は電動機28と直列に接続されている。FLS130のゲートにはFLS駆動回路140が接続されている。FLS駆動回路の駆動信号で、FLS130の通電が調整され、電動機の速度制御が行われる。ゼロクロス検知回路131は、電動機28に供給される交流のゼロクロス点を検知してFLS130が交流に同期した通電制御が行われるようにしたものである。   In the motor drive circuit 113, the FLS 130 (switching element) is connected in series with the motor 28. The FLS driving circuit 140 is connected to the gate of the FLS 130. The energization of the FLS 130 is adjusted by the drive signal of the FLS drive circuit, and the speed control of the motor is performed. The zero-cross detection circuit 131 detects the alternating zero-cross point supplied to the electric motor 28 and performs the energization control in which the FLS 130 is synchronized with the alternating current.

FLS130には並列に電動機のスイッチ132が備わる。電動機28を交流で運転するときはスイッチ132が開かれる。直流で運転するときは閉じられる。スイッチ132の開閉は、切り替え回路133によって行われる。   The FLS 130 is provided with a motor switch 132 in parallel. When the electric motor 28 is operated with alternating current, the switch 132 is opened. Closed when operating on DC. The switch 132 is opened and closed by the switching circuit 133.

発振回路134は、マイコンの駆動パルス信号を供給する。手元表示回路135は、ホース2に備わる手元表示部の表示制御を行う。本体表示回路136は、図9に示した 電池残量を表示する本体表示部137の表示制御を行うものである。   The oscillation circuit 134 supplies a driving pulse signal for the microcomputer. The hand display circuit 135 performs display control of the hand display unit provided in the hose 2. The main body display circuit 136 performs display control of the main body display unit 137 that displays the remaining battery level shown in FIG.

この本体表示部137の表示は、駆動用充電式電池71の電池残量を多い、中、少ないの三段階で表すようにしている。表示仕方は、適宜採用できる。この表示は、充電中に表示が行われないようにしている。充電している間は、表示をしないことにより、電気の無駄をなくすことができるとともに充電時間を早めることができるのである。   The display on the main body display unit 137 is represented in three stages, that is, the remaining battery level of the driving rechargeable battery 71 is large, medium, and small. The display method can be adopted as appropriate. This display prevents display from being performed during charging. By not displaying while charging, waste of electricity can be eliminated and the charging time can be shortened.

この充電非表示は、充電用スイッチ87を設けて充電中には制御回路側への電気の供給が止められるようにしている。他の非表示としては制御回路のソフト的な対応でも可能であるが、充電用スイッチ87によるものが簡単で、かつ電気消費の無駄が少ない。   This charging non-display is provided with a charging switch 87 so that the supply of electricity to the control circuit side is stopped during charging. Other non-displays can be realized by software control of the control circuit. However, the charging switch 87 is simple and the consumption of electricity is small.

駆動用充電式電池71は、電池の使用に伴って低下した電圧が電池の使用停止で回復する特性がある。この使用停止に伴う自然回復の電圧に応じた電池残量を本体表示部137に表示すると、あたかも電池残量がまだ多くあるように思われ、掃除途中で電池が切れになってしまう恐れがある。そこで、ラッチ回路等を利用して充電が行われるまでは、自然回復の電圧に基づく残量表示はしないようにしている。こうすることで、こまめに充電をするようになるので、掃除中の電池切れは解消される。   The driving rechargeable battery 71 has a characteristic that a voltage that is reduced as the battery is used recovers when the battery is stopped. When the remaining battery level corresponding to the voltage of natural recovery accompanying the suspension of use is displayed on the main body display unit 137, it seems that the remaining battery level is still high, and the battery may run out during cleaning. . Therefore, the remaining amount display based on the natural recovery voltage is not performed until charging is performed using a latch circuit or the like. By doing so, the battery is frequently charged, so the battery exhaustion during cleaning is eliminated.

次にプラグ80、充電受接続端子84、コネクターについて、これらに関連するところを含めて図3、6、7、8、10を引用して述べる。   Next, the plug 80, the charge receiving connection terminal 84, and the connector will be described with reference to FIGS.

プラグ80は、後側外カバー21の上部内側に差し込み口が上向きになるように取り付けられる。後側外カバー21の上部には、プラグ80の差し込み口に対向するところが開口部150になっている。開口部150にはシャッター151が備わる。このシャッター151は摺動自在に設けられ、開口部150を閉じたり、開いたりできる。   The plug 80 is attached to the upper inside of the rear outer cover 21 so that the insertion port faces upward. An opening 150 is formed in the upper part of the rear outer cover 21 so as to face the insertion port of the plug 80. The opening 150 is provided with a shutter 151. The shutter 151 is slidably provided, and the opening 150 can be closed or opened.

交流/直流の切替スイッチ82はプラグ80に隣接して配置される。交流/直流の切替スイッチ82には切り替えつまみ152が設けられ、この切り替えつまみ152は前記シャッター151に係止している。このため、シャッター151を摺動することで、交流/直流の切替スイッチ82は、交流側と直流側の切り替えが行われる。開口部150を閉じるように、シャッター151をセットしたときは直流側が選択され、開口部150を開くようにシャッター151をセットしたときは交流側が選択される。直流側を選択したときは、開口部150がシャッター151で閉じられるので、誤ってプラグ80に交流電源が接続されることは防止され、安全である。   The AC / DC changeover switch 82 is disposed adjacent to the plug 80. The AC / DC changeover switch 82 is provided with a changeover knob 152, which is engaged with the shutter 151. Therefore, the AC / DC changeover switch 82 is switched between the AC side and the DC side by sliding the shutter 151. When the shutter 151 is set so as to close the opening 150, the direct current side is selected, and when the shutter 151 is set so as to open the opening 150, the alternating current side is selected. When the DC side is selected, the opening 150 is closed by the shutter 151, so that it is safe to prevent the AC power supply from being accidentally connected to the plug 80.

充電用スイッチ87は、後側外カバー21の上部内側に取り付けられる。この充電用スイッチ87には、押ボタン153が設けられる。押ボタン153を雄と押すと、充電用スイッチ87は開くようになっている。   The charging switch 87 is attached inside the upper portion of the rear outer cover 21. This charging switch 87 is provided with a push button 153. When the push button 153 is pushed with a male, the charging switch 87 is opened.

掃除機本体の後部には、充電受接続凹部154が設けられている。この充電受接続凹部154の内側には、前述した3本の充電受接続端子84が備わる。また充電受接続端子84には、前述した充電用スイッチ87の押ボタン153が突き出すようにおかれる。   A charge receiving connection recess 154 is provided at the rear of the cleaner body. Inside the charge receiving connection recess 154, the three charge receiving connection terminals 84 described above are provided. In addition, the push button 153 of the above-described charging switch 87 protrudes from the charging receiving connection terminal 84.

前述した充電供給接続台8は3本の充電供給接続端子(図示せず)が備わる。充電供給接続台8は、前記充電接続凹部154に着脱自在に嵌合する。この嵌合で、充電供給接続端子は充電受接続端子84には接続される。図1に示すように充電台7に掃除機本体1を載置することにより、充電供給接続台8に前記充電接続凹部154が嵌合し、充電供給接続端子が充電受接続端子84に接続されるとともに押ボタン153が押されて充電用スイッチ87は開かれるのである。前述べたように充電台7に掃除機本体1を載置して充電するときは、充電用スイッチ87の開放で、電池への充電以外は電気の供給は行われない。   The above-described charging / supply connection base 8 is provided with three charging / supply connection terminals (not shown). The charge supply connection base 8 is detachably fitted into the charge connection recess 154. With this fitting, the charge supply connection terminal is connected to the charge receiving connection terminal 84. As shown in FIG. 1, by placing the vacuum cleaner body 1 on the charging base 7, the charging connection recess 154 is fitted into the charging supply connection base 8, and the charging supply connection terminal is connected to the charge receiving connection terminal 84. At the same time, the push button 153 is pushed and the charging switch 87 is opened. As described above, when the vacuum cleaner body 1 is placed on the charging stand 7 for charging, the charging switch 87 is opened, and electricity is not supplied except for charging the battery.

充電受接続端子84につながっている雌コネクタ−100は、前記電池収納部70に引き出せるように置かれる。駆動用充電式電池71につながっている雄コネクター101は前記雌コネクター100に接続される。コネクターの着脱は、電池の交換または点検時に行われる。雌コネクター100は電池収納部70内に引き出せるように置かれているので、コネクターの着脱は容易にでき、しかも、しまうのも用意に行うことができる。   The female connector 100 connected to the charge receiving connection terminal 84 is placed so that it can be pulled out to the battery housing part 70. The male connector 101 connected to the driving rechargeable battery 71 is connected to the female connector 100. The connector is attached / detached at the time of battery replacement or inspection. Since the female connector 100 is placed so as to be able to be pulled out into the battery housing portion 70, the connector can be easily attached and detached, and can be easily prepared.

電気部品カバー155は、プラグ80、充電受接続端子84、交流/直流の切替スイッチ82等を覆うものである。この電機部品カバー155で電動送風機23からの排気を遮ることで、電機部品の汚れを少なくできる。   The electrical component cover 155 covers the plug 80, the charge receiving connection terminal 84, the AC / DC changeover switch 82, and the like. By blocking the exhaust from the electric blower 23 with the electric component cover 155, the contamination of the electric components can be reduced.

次に電動送風機の23の運転に伴う排気について述べる。   Next, the exhaust associated with the operation of the electric blower 23 will be described.

電動送風機23の運転により、塵埃ともに吸引された空気は集塵袋28を通過し、さらにファン部60および電動機61を通過して電動送風機収納室27は排気される。この排気は電動機61を冷却しているので、高温になっている。排気は通り抜け孔42から環状の排気流路(筒部40と上.下ケース10,9の外壁との間に形成されている)に流れ込む。環状排気路を流れて消音された排気はフイルタ室45の細塵フィルタ43を通過する。細塵フィルタ43で排気中の細塵が除去された排気は、仕切壁41で隔てられた排気室46に連通孔47から流れ込む。ここで排気の消音はさらに行われて外部排気穴48より外部に排出される。   Due to the operation of the electric blower 23, the air sucked together with the dust passes through the dust collection bag 28, and further passes through the fan unit 60 and the electric motor 61 to exhaust the electric blower storage chamber 27. Since this exhaust air cools the electric motor 61, it is at a high temperature. Exhaust gas flows from the through hole 42 into an annular exhaust passage (formed between the cylindrical portion 40 and the outer walls of the upper and lower cases 10, 9). The exhaust gas that has been silenced through the annular exhaust passage passes through the fine dust filter 43 in the filter chamber 45. The exhaust gas from which fine dust in the exhaust gas is removed by the fine dust filter 43 flows into the exhaust chamber 46 separated by the partition wall 41 from the communication hole 47. Here, the exhaust sound is further silenced and discharged to the outside through the external exhaust hole 48.

かかる排気は高温であるが、排気を遮る壁で遮断されて駆動用充電式電池71にはあたらない。駆動用充電式電池71が排気で高温に加熱されることはない。また電池収納部70に断熱材72が備わるので、さらに熱の伝わりは抑えられる。
駆動用充電式電池71の温度上昇による破損や動作不良が生じないのである。
Although the exhaust gas is hot, it is blocked by the wall that blocks the exhaust gas and does not hit the driving rechargeable battery 71. The drive rechargeable battery 71 is not heated to a high temperature by exhaust. Moreover, since the battery accommodating part 70 is equipped with the heat insulating material 72, transmission of heat is further suppressed.
The drive rechargeable battery 71 is not damaged or malfunctioned due to a temperature rise.
