Thegrip portion 23 protrudes from thehand operation tube 22 in an appropriate shape that can be easily gripped by the user.

操作部24は、それぞれの運転モードに対応付けられるスイッチを備えている。具体的には、操作部24は、電動送風機8の運転停止操作に対応付けられる停止スイッチ24aと、電動送風機8の運転開始操作に対応付けられる起動スイッチ24bと、吸込口体26への電源供給に対応付けられるブラシスイッチ24cと、を備えている。停止スイッチ24aおよび起動スイッチ24bは、本体制御装置9に電気的に接続されている。電気掃除機1の使用者は、操作部24を操作して電動送風機8の運転モードを択一的に選択できる。起動スイッチ24bは、電動送風機8の運転中に、運転モードの選択スイッチとしても機能している。この場合、本体制御装置9は、起動スイッチ24bから操作信号を受け取る度に運転モードを強→中→弱→強→中→弱→………の順に切り換える。なお、操作部24は、起動スイッチ24bに代えて、強運転スイッチ(図示省略)、中運転スイッチ(図示省略)、および弱運転スイッチ(図示省略)を個別に備えていても良い。  Theoperation unit 24 includes a switch associated with each operation mode.

The user of the vacuum cleaner 1 can alternatively select the operation mode of theelectric blower 8 by operating theoperation unit 24. Thestart switch 24 b also functions as an operation mode selection switch during operation of theelectric blower 8. In this case, every time an operation signal is received from theactivation switch 24b, the main body control device 9 switches the operation mode in the order of strong → medium → weak → strong → medium → weak →. Note that theoperation unit 24 may individually include a strong operation switch (not shown), a medium operation switch (not shown), and a weak operation switch (not shown) instead of thestart switch 24b.

複数の筒状体を重ね合わせたテレスコピック構造の延長管25は、伸縮可能な細長略円筒状の管である。延長管25の一方の端部(ここでは、後方の端部)には、手元操作管22の他方の端部(ここでは、前方の端部)に着脱自在な継手構造が設けられている。延長管25は、手元操作管22、集塵ホース21および接続管19を通じて塵埃分離集塵部7に流体的に接続されている。  Anextension tube 25 having a telescopic structure in which a plurality of cylindrical bodies are superposed is an elongated, substantially cylindrical tube that can be expanded and contracted. One end portion (here, the rear end portion) of theextension tube 25 is provided with a joint structure that is detachable from the other end portion (here, the front end portion) of thehand operation tube 22. Theextension pipe 25 is fluidly connected to the dust separating and collectingpart 7 through thehand operating pipe 22, thedust collecting hose 21 and the connectingpipe 19.

吸込口体26は、木床やカーペットなどの被掃除面上を走行自在または滑走自在であり、走行状態または滑走状態において被掃除面に対向する底面に吸込口28を有する。また、吸込口体26は、吸込口28に配置されている回転自在な回転清掃体29と、回転清掃体29を駆動させる電動機31と、を備えている。吸込口体26の一方の端部(ここでは、後方の端部)には、延長管25の他方の端部(ここでは、前方の端部)に着脱自在な継手構造が設けられている。吸込口体26は、延長管25、手元操作管22、集塵ホース21および接続管19を通じて塵埃分離集塵部7に流体的に接続されている。つまり、吸込口体26、延長管25、手元操作管22、集塵ホース21、接続管19、および塵埃分離集塵部7は、電動送風機8から吸込口28へ至る吸込風路である。電動機31は、ブラシスイッチ24cから操作信号を受け取る度に運転開始と停止とを交互に繰り返す。  Thesuction port body 26 can run or slide on a surface to be cleaned such as a wooden floor or a carpet, and has asuction port 28 on the bottom surface facing the surface to be cleaned in the running state or the sliding state. Thesuction port body 26 includes a rotatablerotary cleaning body 29 disposed in thesuction port 28 and anelectric motor 31 that drives therotary cleaning body 29. One end portion (here, the rear end portion) of thesuction port body 26 is provided with a joint structure that is detachable from the other end portion (here, the front end portion) of theextension pipe 25. Thesuction port body 26 is fluidly connected to the dust separating and collectingpart 7 through theextension pipe 25, thehand operating pipe 22, thedust collecting hose 21 and the connectingpipe 19. That is, thesuction port body 26, theextension tube 25, thehand operation tube 22, thedust collection hose 21, theconnection tube 19, and the dust separation anddust collection unit 7 are suction air paths from theelectric blower 8 to thesuction port 28. Theelectric motor 31 alternately starts and stops operation every time it receives an operation signal from thebrush switch 24c.

電気掃除機1は、起動スイッチ24bに対する使用者の操作を受け付けると電動送風機8を始動させる。例えば、電気掃除機1は、電動送風機8が停止している状態で起動スイッチ24bに対する操作を受け付けると、先ず電動送風機8を強運転モードで運転し、再び起動スイッチ24bに対する操作を受け付けると電動送風機8を中運転モードで運転し、三度、起動スイッチ24bに対する操作を受け付けると電動送風機8を弱運転モードで運転し、以下同様に繰り返す。強運転モード、中運転モードおよび弱運転モードは、予め設定される複数の運転モードであり、強運転モード、中運転モード、弱運転モードの順に電動送風機8に対する入力値が小さい。始動した電動送風機8は、塵埃分離集塵部7から空気を排気してその内部を負圧にする。  The electric vacuum cleaner 1 starts theelectric blower 8 when accepting a user operation on thestart switch 24b. For example, when the vacuum cleaner 1 receives an operation on thestart switch 24b while theelectric blower 8 is stopped, the electric blower first operates theelectric blower 8 in the strong operation mode, and receives an operation on thestart switch 24b again. 8 is operated in the medium operation mode, and when the operation for thestart switch 24b is accepted three times, theelectric blower 8 is operated in the weak operation mode, and the same is repeated thereafter. The strong operation mode, the medium operation mode, and the weak operation mode are a plurality of operation modes set in advance, and the input value to theelectric blower 8 is small in the order of the strong operation mode, the medium operation mode, and the weak operation mode. The startedelectric blower 8 exhausts air from the dust separation andcollection unit 7 to make the inside negative.

塵埃分離集塵部7内の負圧は、本体接続口12、接続管19、集塵ホース21、手元操作管22、延長管25、および吸込口体26を順次に通じて吸込口28に作用する。電気掃除機1は、吸込口28に作用した負圧によって、被掃除面上の塵埃を空気とともに吸い込んで被掃除面を掃除する。塵埃分離集塵部7は、電気掃除機1に吸い込まれた含塵空気から塵埃を分離し、蓄積する一方で、含塵空気から分離した空気を電動送風機8へ送る。電動送風機8は、塵埃分離集塵部7から吸い込んだ空気を掃除機本体2外へ排気する。  The negative pressure in the dust separating and collectingpart 7 acts on thesuction port 28 through the mainbody connection port 12, theconnection tube 19, thedust collection hose 21, thehand control tube 22, theextension tube 25, and thesuction port body 26 in order. To do. The vacuum cleaner 1 cleans the surface to be cleaned by sucking dust on the surface to be cleaned together with air by the negative pressure applied to thesuction port 28. The dust separating and collectingunit 7 separates and accumulates dust from the dust-containing air sucked into the vacuum cleaner 1, and sends the air separated from the dust-containing air to theelectric blower 8. Theelectric blower 8 exhausts the air sucked from the dust separating and collectingunit 7 to the outside of the cleaner body 2.

The switchingelement 42 changes the input of theelectric blower 8 according to the change of the gate current.

制御用電源部43は、二次電池4から制御回路41へ供給される電源の電圧を制御用電源電圧に変換して本体制御装置9へ供給する。  The controlpower supply unit 43 converts the power supply voltage supplied from the secondary battery 4 to thecontrol circuit 41 into a control power supply voltage and supplies the control power supply voltage to the main body control device 9.

接続判定部45および制御部46は、本体制御装置9で実行されるプログラムである。本体制御装置9は、マイクロコンピュータからなり、中央処理部(図示省略)、記憶部48、I/O部(図示省略)およびタイマ(図示省略)を備えている。  Theconnection determination unit 45 and thecontrol unit 46 are programs executed by the main body control device 9.

The main body control device 9 performs secondary battery recognition control for determining whether the secondary battery 4 is a genuine product or a non-genuine product while performing bidirectional communication with the secondary battery 4.

また、本体制御装置9は、操作部24が出力する操作信号を周期的に読み取り、選択された運転モードにしたがってスイッチング素子42のスイッチング制御を行い電動送風機8の入力を変化させる。  In addition, the main body control device 9 periodically reads the operation signal output from theoperation unit 24, performs switching control of the switchingelement 42 according to the selected operation mode, and changes the input of theelectric blower 8.

さらに、本体制御装置9は、例えば、弱、中および強からなる3つの運転モードに応じて電動送風機8の入力を変化させる。本体制御装置9は、起動スイッチ24bから操作信号を受け取る都度、運転モードを順次に切り換えてスイッチング素子42のスイッチング制御を行う。  Furthermore, the main body control device 9 changes the input of theelectric blower 8 according to, for example, three operation modes consisting of weak, medium and strong. The main body control device 9 performs switching control of the switchingelement 42 by sequentially switching the operation mode each time an operation signal is received from thestart switch 24b.

報知部47は、電気掃除機1の使用者に視覚情報で報知するランプや液晶モニターなどの表示装置や、電気掃除機1の使用者に聴覚情報で報知する例えばスピーカーである。報知部47は、本体制御装置9の指令に従って、掃除機本体2に非正規の二次電池4が接続されたことを報知する。  Thenotification unit 47 is a display device such as a lamp or a liquid crystal monitor that notifies the user of the vacuum cleaner 1 with visual information, or a speaker that notifies the user of the vacuum cleaner 1 with auditory information. Thenotification unit 47 notifies that the non-regular secondary battery 4 is connected to the cleaner body 2 in accordance with a command from the main body control device 9.

本体制御装置9が実行する二次電池認識制御について説明する。  The secondary battery recognition control executed by the main body control device 9 will be described.

図3は、本実施形態に係る電気掃除機の二次電池認識制御を示すフローチャートである。  FIG. 3 is a flowchart showing the secondary battery recognition control of the vacuum cleaner according to the present embodiment.

図3に示すように、本実施形態に係る電気掃除機1は、二次電池4が掃除機本体2に装着されて、二次電池4から制御回路41に電圧が印加されると制御用電源部43から本体制御装置9へ電源を供給し、本体制御装置9を起動させる(ステップS1)。そして、本体制御装置9が起動すると、本体制御装置9の接続判定部45は、二次電池4へ確認信号を送信する(ステップS2)。この確認信号は、本体制御装置9の記憶部48に予め記憶される任意の情報である。  As shown in FIG. 3, the vacuum cleaner 1 according to the present embodiment has a control power supply when the secondary battery 4 is attached to the cleaner body 2 and a voltage is applied from the secondary battery 4 to thecontrol circuit 41. Power is supplied from theunit 43 to the main body control device 9, and the main body control device 9 is activated (step S1). And when the main body control apparatus 9 starts, theconnection determination part 45 of the main body control apparatus 9 will transmit a confirmation signal to the secondary battery 4 (step S2). This confirmation signal is arbitrary information stored in advance in thestorage unit 48 of the main body control device 9.

二次電池4は、掃除機本体2側の本体制御装置9から確認信号を取得する(ステップS3)と、この確認信号と電池側照合用情報との一致を照合する(ステップS4)。この電池側照合用情報は、二次電池4の保護回路に予め記憶されている。二次電池4は、確認信号と電池側照合用情報との一致を確認した場合には(ステップS4 一致)、一致確認を識別する情報(一致情報)を含む確認応答信号を接続判定部45へ返信する(ステップS5)。他方、二次電池4は、確認信号と電池側照合用情報との不一致を確認した場合には(ステップS4 不一致)、不一致確認を識別する情報(不一致情報)を含む確認応答信号を接続判定部45へ返信する(ステップS6)。  When the secondary battery 4 acquires the confirmation signal from the main body control device 9 on the cleaner body 2 side (step S3), the secondary battery 4 collates the coincidence between the confirmation signal and the battery side verification information (step S4). This battery side verification information is stored in advance in the protection circuit of the secondary battery 4. When the secondary battery 4 confirms a match between the confirmation signal and the battery side verification information (match in step S4), the secondary battery 4 sends a confirmation response signal including information identifying the match confirmation (match information) to theconnection determination unit 45. A reply is made (step S5). On the other hand, when the secondary battery 4 confirms the mismatch between the confirmation signal and the battery-side verification information (step S4 mismatch), the secondary battery 4 sends a confirmation response signal including information (mismatch information) for identifying the mismatch confirmation to the connection determination unit. It returns to 45 (step S6).

接続判定部45は、二次電池4から確認応答信号を取得する(ステップS7)と、この確認応答信号と本体側照合用情報との一致を照合する(ステップS8)。接続判定部45は、確認応答信号と本体側照合用情報との一致を確認した場合には(ステップS8 一致)、一致確認を確定する(ステップS9)。他方、接続判定部45は、確認応答信号と本体側照合用情報との不一致を確認した場合には(ステップS8 不一致)、不一致確認を確定する(ステップS10)。なお、確認応答信号は、確認信号と電池側照合用情報とを照合した結果から二次電池4が生成する信号であって、接続判定部45が二次電池4へ送信する確認信号とは異なる。換言すれば、接続判定部45は、相互に異なる確認信号および本体照合用情報を記憶している。  When theconnection determination unit 45 obtains the confirmation response signal from the secondary battery 4 (step S7), theconnection determination unit 45 collates the match between the confirmation response signal and the main body side verification information (step S8). When thematch determination unit 45 confirms the match between the confirmation response signal and the main body side verification information (match in step S8), theconnection determination unit 45 finalizes the match check (step S9). On the other hand, if theconnection determination unit 45 confirms a mismatch between the confirmation response signal and the main body side verification information (step S8 mismatch), theconnection determination unit 45 determines the mismatch confirmation (step S10). The confirmation response signal is a signal generated by the secondary battery 4 from the result of collating the confirmation signal and the battery side verification information, and is different from the confirmation signal transmitted from theconnection determination unit 45 to the secondary battery 4. . In other words, theconnection determination unit 45 stores different confirmation signals and body verification information.

制御部46は、接続判定部45が一致確認を確定している場合(ステップS9)には、電動送風機8の運転を許可し(ステップS11)、二次電池認識制御を終了させる。この後、制御部46は、操作部24で選択される運転モードにしたがって電動送風機8を運転する。  When theconnection determination unit 45 has confirmed the coincidence confirmation (step S9), thecontrol unit 46 permits the operation of the electric blower 8 (step S11) and ends the secondary battery recognition control. Thereafter, thecontrol unit 46 operates theelectric blower 8 according to the operation mode selected by theoperation unit 24.

他方、制御部46は、接続判定部45が不一致確認を確定している場合(ステップS10)には、電動送風機8の運転を禁止し(ステップS12)、二次電池認識制御を終了させる。この後、制御部46は、操作部24で選択される運転モードに関わらず電動送風機8への電源供給を遮断して運転を禁止する。また、制御部46は、報知部47によって二次電池4が非正規品であることを使用者へ報知する。さらに、制御部46は、二次電池4が非正規品であることを記憶部48へ記憶させる。  On the other hand, when theconnection determination unit 45 has confirmed the mismatch (step S10), thecontrol unit 46 prohibits the operation of the electric blower 8 (step S12) and ends the secondary battery recognition control. Thereafter, thecontrol unit 46 blocks the power supply to theelectric blower 8 and prohibits the operation regardless of the operation mode selected by theoperation unit 24. Further, thecontrol unit 46 notifies the user that the secondary battery 4 is an unauthorized product by thenotification unit 47. Further, thecontrol unit 46 causes thestorage unit 48 to store that the secondary battery 4 is an irregular product.

ところで、非正規品の二次電池4は、本体制御装置9が二次電池4へ送信する確認信号を受信する機能、確認信号と電池側照合用情報との一致を照合する機能、および確認応答信号を接続判定部45へ返信する機能の一部または全部を備えていない場合がある。この場合、非正規品の二次電池4は当然、ステップS3からステップS6を処理しない。そうすると、接続判定部45は、ステップS7で二次電池4から確認応答信号を取得できない。  By the way, the non-genuine secondary battery 4 has a function of receiving a confirmation signal transmitted from the main body control device 9 to the secondary battery 4, a function of collating the confirmation signal with the battery side collation information, and a confirmation response. There may be cases where some or all of the function of returning a signal to theconnection determination unit 45 is not provided. In this case, the non-genuine secondary battery 4 naturally does not process steps S3 to S6. If it does so, theconnection determination part 45 cannot acquire a confirmation response signal from the secondary battery 4 by step S7.

そこで、接続判定部45は、二次電池4へ確認信号を送信(ステップS2)した後、予め定める所定の時間(例えば0.5秒程度)が経過しても、二次電池4から確認応答信号を取得する(ステップS7)ことができない場合には、ステップS3からステップS8を迂回し、確認応答信号と本体側照合用情報との不一致を確定し(ステップS10)、電動送風機8の運転を禁止し(ステップS12)、二次電池認識制御を終了させる。この後、制御部46は、操作部24で選択される運転モードに関わらず電動送風機8への電源供給を遮断して運転を禁止する。また、制御部46は、報知部47によって二次電池4が非正規品であることを使用者へ報知する。さらに、制御部46は、二次電池4が非正規品であることを記憶部48へ記憶させる。  Therefore, theconnection determination unit 45 transmits a confirmation response signal from the secondary battery 4 even after a predetermined time (for example, about 0.5 seconds) has elapsed after transmitting the confirmation signal to the secondary battery 4 (step S2). If it cannot be obtained (step S7), the process bypasses steps S3 to S8, confirms the mismatch between the confirmation response signal and the main body side verification information (step S10), and prohibits the operation of theelectric blower 8. (Step S12), the secondary battery recognition control is terminated. Thereafter, thecontrol unit 46 blocks the power supply to theelectric blower 8 and prohibits the operation regardless of the operation mode selected by theoperation unit 24. Further, thecontrol unit 46 notifies the user that the secondary battery 4 is an unauthorized product by thenotification unit 47. Further, thecontrol unit 46 causes thestorage unit 48 to store that the secondary battery 4 is an irregular product.

このように、本実施形態に係る電気掃除機1は、二次電池4が掃除機本体2に装着されたときのみに二次電池4へ確認信号を送信し、かつ二次電池4から取得する受信信号と照合用情報との一致を照合することによって、従来の電気掃除機に比べて二次電池4が正規品であるか否かの確認を大幅に省電力化できる。  As described above, the electric vacuum cleaner 1 according to the present embodiment transmits a confirmation signal to the secondary battery 4 only when the secondary battery 4 is attached to the cleaner body 2 and acquires the confirmation signal from the secondary battery 4. By verifying the match between the received signal and the verification information, it is possible to greatly reduce power consumption in confirming whether or not the secondary battery 4 is a genuine product as compared with a conventional vacuum cleaner.

また、本実施形態に係る電気掃除機1は、相互に異なる確認信号および本体照合用情報を記憶していることによって、掃除機本体2側および二次電池4側の双方で互いに相手方が正規品であるか否かを確かめ合うことができる。  Moreover, the vacuum cleaner 1 which concerns on this embodiment memorize | stores the mutually different confirmation signal and the information for main body collation, and the other party is a regular article mutually in both the cleaner main body 2 side and the secondary battery 4 side. It can be confirmed whether or not.

さらに、本実施形態に係る電気掃除機1は、報知部47を備えるため、例えば使用者が知らずに非正規品の二次電池4を掃除機本体2に接続するような場合であって、電動送風機8が駆動せず、電気掃除機1の故障を疑うような状況になったとしても、電動送風機8の駆動しない原因を使用者へ確実に報知して適切な対処を促すことができる。  Furthermore, since the vacuum cleaner 1 according to the present embodiment includes thenotification unit 47, for example, a case where the non-genuine secondary battery 4 is connected to the cleaner body 2 without the user's knowledge, Even if theblower 8 is not driven and the vacuum cleaner 1 is suspected of being broken, it is possible to reliably notify the user of the cause of theelectric blower 8 not being driven and to take appropriate measures.

さらにまた、本実施形態に係る電気掃除機1は、記憶部48を備えるため、非正規品の二次電池4が接続されることによって掃除機本体2側に故障の懸念を生じるような場合には、以後、電動送風機8の駆動を禁じて製造元での点検を促進したり、故障が生じた掃除機本体2の故障原因を究明する際に非正規品の二次電池4の使用履歴を確認して迅速な原因究明に資するなど、保守やアフターサービスにおける利便性を高めることができる。  Furthermore, since the vacuum cleaner 1 according to the present embodiment includes thestorage unit 48, when the non-genuine secondary battery 4 is connected, there is a risk of failure on the cleaner body 2 side. After that, forbid the driving of theelectric blower 8 to promote the inspection at the manufacturer, or check the usage history of the non-genuine secondary battery 4 when investigating the cause of the failure of the vacuum cleaner body 2 where the failure occurred As a result, it is possible to improve convenience in maintenance and after-sales service, such as contributing to quick cause investigation.

したがって、本発明に係る電気掃除機1によれば、掃除機本体2に正規の二次電池4が装着されているか否かの確認を省電力化することができる。  Therefore, according to the vacuum cleaner 1 which concerns on this invention, the confirmation whether the regular secondary battery 4 is mounted | worn with the vacuum cleaner main body 2 can be saved.

なお、本実施形態に係る電気掃除機1は、キャニスタ型のものに限らず、アップライト型、スティック型、あるいはハンディ型などのものであってもよい。また、電気掃除機1は、商用交流電源Eの他に二次電池を備えたコードレス型のものであってもよい。  The vacuum cleaner 1 according to the present embodiment is not limited to a canister type, but may be an upright type, a stick type, or a handy type. The vacuum cleaner 1 may be of a cordless type provided with a secondary battery in addition to the commercial AC power source E.

本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
