Description

電気掃除機Electric vacuum cleaner
　把持部を把持して吸込口体を移動させる電気掃除機に関する。 It relates to a vacuum cleaner that grips the grip and moves the suction port.
　従来の電気掃除機は特許文献１に開示されている。この電気掃除機は電動送風機を内装する本体部を備え、本体部の下方に吸込口体が本体部に対して回動自在に連結された縦型に構成される。吸込口体は床面に対向する吸気口が開口して床面に摺動する。本体部には着脱自在の延長パイプが上方に延びて配され、延長パイプの上端には使用者が把持する把持部が設けられる。また、本体部の上面には使用者の操作によって電動送風機のオンオフを行う操作部が設けられる。 A conventional vacuum cleaner is disclosed in Patent Document 1. This vacuum cleaner is provided with a main body part that houses an electric blower, and is configured in a vertical type in which a suction port body is rotatably connected to the main body part below the main body part. The suction port body slides on the floor surface with the intake port facing the floor surface opened. A detachable extension pipe extends upward in the main body, and a gripping part that a user grips is provided on the upper end of the extension pipe. In addition, an operation unit for turning on and off the electric blower by a user operation is provided on the upper surface of the main body.
　操作部の操作によって電動送風機が駆動されると、把持部の操作によって吸込口体が本体部とともに移動して床面上を摺動する。これにより、床面の掃除が行われる。この時、本体部は直立した状態から吸込口体に対して回動して傾斜し、把持部を前後方向に移動操作することによって吸込口体が前後に移動する。掃除が終了すると操作部の操作によって電動送風機が停止され、本体部を立設して電気掃除機が収納される。 When the electric blower is driven by the operation of the operation unit, the suction port body moves together with the main body unit by the operation of the gripping unit and slides on the floor surface. Thereby, the floor surface is cleaned. At this time, the main body portion rotates and tilts with respect to the suction port body from an upright state, and the suction port body moves back and forth by operating the grip portion to move in the front-rear direction. When the cleaning is completed, the electric blower is stopped by the operation of the operation unit, the main body unit is erected and the electric vacuum cleaner is stored.
　また、従来の他の電気掃除機は特許文献２に開示されている。この電気掃除機は電動送風機を内装する本体部に可撓性の接続ホースが接続されたキャニスター型に構成される。接続ホースの先端には使用者が把持する把持部が設けられるとともに延長パイプが連結される。延長パイプには床面に対向する吸気口を開口した吸込口体が連結される。 Further, another conventional vacuum cleaner is disclosed in Patent Document 2. This electric vacuum cleaner is configured in a canister type in which a flexible connecting hose is connected to a main body portion that houses an electric blower. A gripping part to be gripped by the user is provided at the tip of the connection hose and an extension pipe is connected. The extension pipe is connected to a suction port body having an intake port facing the floor surface.
　把持部の近傍には電動送風機の運転状態を指示する操作部が設けられる。操作部は「切」ボタン、「強」ボタン、「中」ボタン、「弱」ボタン等の複数の操作ボタンを有している。「強」ボタンは電動送風機を所定の出力（回転数）で駆動する。「中」ボタンは電動送風機を「強」ボタンによる駆動時よりも低い出力で駆動する。「弱」ボタンは電動送風機を「中」ボタンによる駆動時よりも低い出力で駆動する。「切」ボタンは電動送風機を停止する。 An operation unit for instructing the operating state of the electric blower is provided in the vicinity of the grip unit. The operation unit has a plurality of operation buttons such as a “OFF” button, a “strong” button, a “middle” button, and a “weak” button. The “strong” button drives the electric blower at a predetermined output (number of rotations). The “middle” button drives the electric blower at a lower output than when driven by the “strong” button. The “weak” button drives the electric blower at a lower output than when driven by the “middle” button. The “OFF” button stops the electric blower.
　操作部の「強」ボタン等を手指で押下すると操作ボタンに応じた出力で電動送風機が駆動される。そして、把持部を前後方向に移動操作することによって吸込口体が前後に移動して床面上を摺動して床面の掃除が行われる。掃除中に「強」ボタン、「中」ボタン、「弱」ボタンを押下すると、電動送風機の出力が可変される。これにより、被掃除面に応じて強力に塵埃を吸い込んで掃除を行う場合や、電力消費を抑制して弱い吸引力で掃除を行う場合等を使い分けることができる。掃除が終了すると操作部の「切」ボタンが押下され、電動送風機が停止する。 When the “strong” button on the operation unit is pressed with a finger, the electric blower is driven with an output corresponding to the operation button. Then, by moving the grip portion in the front-rear direction, the suction port body moves back and forth and slides on the floor surface to clean the floor surface. When the “strong” button, “medium” button, and “weak” button are pressed during cleaning, the output of the electric blower is varied. Thereby, it is possible to properly use the case where the dust is strongly sucked in accordance with the surface to be cleaned and the case where the cleaning is performed with a weak suction force while suppressing the power consumption. When cleaning is completed, the “OFF” button on the operation unit is pressed, and the electric blower stops.

　しかしながら、特許文献１の電気掃除機によると、操作部が本体部に設けられるため、掃除の開始時及び終了時に使用者は手元から離れた操作部を操作する必要がある。このため、電気掃除機の利便性が悪い問題があった。 However, according to the electric vacuum cleaner of Patent Document 1, since the operation unit is provided in the main body, the user needs to operate the operation unit away from the hand at the start and end of cleaning. For this reason, there existed a problem that the convenience of a vacuum cleaner was bad.
　使用者の手元で操作できるように操作部を把持部に設けると構造が複雑になるため電気掃除機が大型化する。縦型の電気掃除機は本体部と一体に吸込口体を移動させるため小型軽量化する必要があり、大型化されると利便性が低下する問題がある。 ¡If the operation part is provided in the grip part so that it can be operated by the user, the structure becomes complicated and the vacuum cleaner becomes larger. The vertical vacuum cleaner needs to be reduced in size and weight in order to move the suction port body integrally with the main body, and there is a problem that convenience is reduced when the size is increased.
　また、特許文献２の電気掃除機によると、操作部が複数の操作ボタンを有するため、把持部を把持しながら全ての操作ボタンに手指が届かない場合がある。このため、電動送風機の出力を可変する際に把持部の把持位置を持ち替えて所望の操作ボタンを押下する必要がある。従って、電気掃除機の利便性が悪い問題があった。 In addition, according to the electric vacuum cleaner of Patent Document 2, since the operation unit has a plurality of operation buttons, fingers may not reach all the operation buttons while holding the holding unit. For this reason, when changing the output of the electric blower, it is necessary to change the holding position of the holding portion and press a desired operation button. Therefore, there is a problem that the convenience of the vacuum cleaner is poor.

Thereby, as shown in FIG. 3, the holding part 8 can be hold | gripped and the extension pipe 6 can clean a ceiling surface, the air conditioner attached to the wall surface, etc. can be performed. Further, as shown in FIG. 4, the grip 8 can be detached from the extension pipe 6 by pressing the removal button 12. Thereby, as shown in FIG. 5, the holding part 8 can be hold | gripped and a desk top etc. can be cleaned.
　図６は電気掃除機１の構成を示すブロック図である。電気掃除機１は本体部４内に設けられた制御部２により各部が制御される。制御部２には電動送風機３、操作部１３、記憶部１４、表示部１５、加速度センサ１６、延長パイプ着脱検知スイッチ１７が接続される。 FIG. 6 is a block diagram showing the configuration of the electric vacuum cleaner 1. Each part of the vacuum cleaner 1 is controlled by a control unit 2 provided in the main body 4. The electric blower 3, the operation unit 13, the storage unit 14, the display unit 15, the acceleration sensor 16, and the extension pipe attachment / detachment detection switch 17 are connected to the control unit 2.
　記憶部１４は電気掃除機１の動作プログラムを格納するとともに制御部２による演算結果を一時記憶する。表示部１５は本体部４に設けられたＬＥＤ等から成り、電気掃除機１の動作状態を表示する。延長パイプ着脱検知スイッチ１７は延長パイプ６の着脱状態を検知する。 The storage unit 14 stores an operation program of the vacuum cleaner 1 and temporarily stores a calculation result by the control unit 2. The display unit 15 includes an LED or the like provided in the main body unit 4 and displays the operation state of the vacuum cleaner 1. The extension pipe attachment / detachment detection switch 17 detects the attachment / detachment state of the extension pipe 6.
　加速度センサ１６は本体部４に設けられ、重力加速度を含む加速度を検出して本体部４の姿勢を検知する。本実施形態では、本体部４が鉛直に対して前後方向及び左右方向に２５゜以内で立設した際に直立状態と判定している。把持部８から手を離して本体部４が傾斜しても倒れない状態になったときを直立状態と判定してもよい。 The acceleration sensor 16 is provided in the main body 4 and detects the posture of the main body 4 by detecting acceleration including gravitational acceleration. In the present embodiment, it is determined that the main body portion 4 is in the upright state when it is erected within 25 ° in the front-rear direction and the left-right direction with respect to the vertical. When the hand 4 is released and the main body 4 is tilted, it may be determined to be in an upright state.
　また、本体部４が鉛直に対して後方に５０゜以上傾斜した場合に把持部８を把持して本体部４が傾斜された傾斜状態と判定している。また、本体部４が鉛直に対して前方または左右方向に５５゜以上倒れた場合に、把持部８から手を離して本体部４が接地された接地状態と判定している。尚、本体部４が鉛直に対して後方に所定の角度範囲の時に傾斜状態と判定し、傾斜状態よりも大きい角度になったときに接地状態と判定してもよい。 Further, when the main body part 4 is inclined backward by 50 ° or more with respect to the vertical, it is determined that the main body part 4 is inclined by gripping the holding part 8. Further, when the main body part 4 is tilted 55 ° or more forward or in the left-right direction with respect to the vertical, it is determined that the main body part 4 is grounded by releasing the hand from the grip part 8. The main body 4 may be determined to be in the inclined state when it is in a predetermined angle range backward with respect to the vertical, and may be determined to be in the grounding state when the angle is larger than the inclined state.
　図７は電気掃除機１の動作を示すフローチャートである。電気掃除機１が商用電源に接続されると動作プログラムが開始され、ステップ＃１１でスタンバイモードがデフォルトに設定されているか否かが判断される。スタンバイモードがデフォルトに設定されている場合はステップ＃２０に移行する。 FIG. 7 is a flowchart showing the operation of the vacuum cleaner 1. When the vacuum cleaner 1 is connected to a commercial power source, an operation program is started, and it is determined in step # 11 whether the standby mode is set to default. If the standby mode is set to the default, the process proceeds to step # 20.
　スタンバイモードがデフォルトに設定されていない場合は通常モードが開始され、ステップ＃１２に移行する。ステップ＃１２では「強」ボタンが押下されたか否かが判断される。「強」ボタンが押下されていない場合はステップ＃１３で「弱」ボタンが押下されたか否かが判断される。 If the standby mode is not set to the default, the normal mode is started and the process proceeds to step # 12. In step # 12, it is determined whether or not the “strong” button has been pressed. If the “strong” button has not been pressed, it is determined in step # 13 whether or not the “weak” button has been pressed.
　「弱」ボタンが押下されていない場合はステップ＃１４で「停止」ボタンが押下されたか否かが判断される。「停止」ボタンが押下されていない場合はステップ＃１５で「スタンバイ」ボタンが押下されたか否かが判断される。「スタンバイ」ボタンが押下されていない場合はステップ＃１２に戻り、いずれかの操作ボタンが押下されるまでステップ＃１２～＃１５が繰り返される。 If the “weak” button has not been pressed, it is determined in step # 14 whether or not the “stop” button has been pressed. If the “stop” button has not been pressed, it is determined in step # 15 whether or not the “standby” button has been pressed. If the “standby” button has not been pressed, the process returns to step # 12, and steps # 12 to # 15 are repeated until any operation button is pressed.
　「強」ボタンが押下されると、ステップ＃１６で電動送風機３が高い回転数で駆動される。これにより、把持部８により吸込口体５を移動させて床面の掃除が行われる。「弱」ボタンが押下されると、ステップ＃１７で電動送風機３がステップ＃１６よりも低い回転数で駆動される。これにより、把持部８により吸込口体５を移動させて床面の掃除が行われる。この時、電動送風機３の回転数が低いため、省電力で掃除を行うことができる。 When the “strong” button is pressed, the electric blower 3 is driven at a high rotational speed in step # 16. Thereby, the suction port body 5 is moved by the holding part 8 and the floor surface is cleaned. When the “weak” button is pressed, the electric blower 3 is driven at a lower rotational speed than in step # 16 in step # 17. Thereby, the suction port body 5 is moved by the holding part 8 and the floor surface is cleaned. At this time, since the rotation speed of the electric blower 3 is low, cleaning can be performed with power saving.
　「停止」ボタンが押下されると、ステップ＃１８で電動送風機３が停止される。これにより、掃除が終了する。尚、延長パイプ６を本体部４から取り外した状態や把持部８を延長パイプ６から取り外した状態で「強」ボタンまたは「弱」ボタンを押下すると、電動送風機３が駆動される。これにより、天井面や机上等の掃除が行われる。 When the “stop” button is pressed, the electric blower 3 is stopped in step # 18. Thereby, cleaning is completed. When the “strong” button or the “weak” button is pressed in a state where the extension pipe 6 is removed from the main body portion 4 or the gripping portion 8 is removed from the extension pipe 6, the electric blower 3 is driven. Thereby, a ceiling surface, a desk top, etc. are cleaned.
　「スタンバイ」ボタンが押下されると、ステップ＃１９で電動送風機３が停止される。そして、ステップ＃２０でスタンバイモードに移行する。スタンバイモードは加速度センサ１６の検知結果に基づいて電動送風機３の駆動及び停止を行う。 When the “standby” button is pressed, the electric blower 3 is stopped in step # 19. Then, in step # 20, a transition is made to the standby mode. In the standby mode, the electric blower 3 is driven and stopped based on the detection result of the acceleration sensor 16.
　図８はスタンバイモードの動作を示すフローチャートである。ステップ＃３１、＃３２は本体部４の直立を待機する直立待機状態になっている。ステップ＃３１は直立待機状態に移行してから所定時間（ここでは、１０秒）が経過したか否かが判断される。直立待機状態に移行してから所定時間が経過した場合は図７のフローチャートに戻る。 FIG. 8 is a flowchart showing the operation in the standby mode. Steps # 31 and # 32 are in an upright standby state in which the main body 4 is on standby. In step # 31, it is determined whether or not a predetermined time (here, 10 seconds) has elapsed since the transition to the upright standby state. When a predetermined time has elapsed since the transition to the upright standby state, the flow returns to the flowchart of FIG.
　直立待機状態に移行してから所定時間が経過していない場合はステップ＃３２に移行する。ステップ＃３２では加速度センサ１６の検知によって本体部４が直立したか否かが判断される。本体部４が直立していない場合はステップ＃３１に戻り、ステップ＃３１、＃３２が繰り返し行われて本体部４の直立状態を待機する。 If the predetermined time has not elapsed since the transition to the upright standby state, the process proceeds to step # 32. In step # 32, it is determined whether or not the main body 4 is upright by detection of the acceleration sensor 16. If the main body 4 is not upright, the process returns to step # 31, and steps # 31 and # 32 are repeated to wait for the upright state of the main body 4.
　直立待機状態から本体部４の直立状態を加速度センサ１６により検知すると、ステップ＃３３に移行する。この時、使用者の意図に反した一瞬の動作によって直立状態が検知されないように、直立状態が所定時間（例えば、０．５秒）継続したときにステップ＃３３に移行させている。 If the acceleration sensor 16 detects the upright state of the main body 4 from the upright standby state, the process proceeds to step # 33. At this time, when the upright state continues for a predetermined time (for example, 0.5 seconds), the process proceeds to step # 33 so that the upright state is not detected by an instantaneous operation contrary to the user's intention.
　ステップ＃３３～＃３９は本体部４の傾斜を待機する傾斜待機状態になっている。ステップ＃３３では傾斜待機状態に移行してから所定時間（ここでは、１分）が経過したか否かが判断される。傾斜待機状態に移行してから所定時間が経過した場合は図７のフローチャートに戻る。 Steps # 33 to # 39 are in a stand-by state for waiting for the tilt of the main body 4. In step # 33, it is determined whether or not a predetermined time (in this case, 1 minute) has elapsed since the transition to the tilt standby state. When a predetermined time has elapsed since the transition to the tilt standby state, the flow returns to the flowchart of FIG.
　傾斜待機状態に移行してから所定時間が経過していない場合はステップ＃３４に移行する。ステップ＃３４では加速度センサ１６の検知によって本体部４が接地されたか否かが判断される。本体部４が接地された場合はステップ＃３１に戻り、直立待機状態に移行する。この時、使用者の意図に反した一瞬の動作によって接地状態が検知されないように、接地状態が所定時間（例えば、２秒）継続したときにステップ＃３１に移行させている。 If the predetermined time has not elapsed since the transition to the tilt standby state, the process proceeds to step # 34. In step # 34, it is determined whether or not the main body 4 is grounded by the detection of the acceleration sensor 16. When the main body 4 is grounded, the process returns to step # 31 and shifts to an upright standby state. At this time, when the grounding state continues for a predetermined time (for example, 2 seconds), the process proceeds to step # 31 so that the grounding state is not detected by an instantaneous operation contrary to the user's intention.
　本体部４が接地されていない場合はステップ＃３５で延長パイプ着脱検知スイッチ１７の検知によって延長パイプ６が取り外されたか否かが判断される。延長パイプ６が取り外されていない場合はステップ＃３９に移行する。延長パイプ６が取り外された場合はステップ＃３６で電動送風機３が駆動される。これにより、操作部３の操作を行わずに天井面等を掃除することができる。この時、電動送風機３の回転数は予め設定した回転数にしてもよく、前回電動送風機３を駆動したときの回転数にしてもよい。 If the main body 4 is not grounded, it is determined in step # 35 whether or not the extension pipe 6 has been removed by detection of the extension pipe attachment / detachment detection switch 17. If the extension pipe 6 has not been removed, the process proceeds to step # 39. When the extension pipe 6 is removed, the electric blower 3 is driven at step # 36. Thereby, a ceiling surface etc. can be cleaned, without operating the operation part 3. FIG. At this time, the rotation speed of the electric blower 3 may be set to a preset rotation speed, or may be the rotation speed when the previous electric blower 3 was driven.
　ステップ＃３７では延長パイプ６が装着されるまで待機する。延長パイプ６が装着されると、ステップ＃３８で電動送風機３が停止される。 In step # 37, the process waits until the extension pipe 6 is attached. When the extension pipe 6 is attached, the electric blower 3 is stopped at step # 38.
　ステップ＃３９では加速度センサ１６の検知によって本体部４が傾斜したか否かが判断される。本体部４が傾斜していない場合はステップ＃３３に戻り、ステップ＃３３～＃３９が繰り返し行われて本体部４の傾斜状態を待機する。 In step # 39, it is determined whether or not the main body 4 is tilted by the detection of the acceleration sensor 16. If the main body 4 is not tilted, the process returns to step # 33, and steps # 33 to # 39 are repeatedly performed to wait for the tilted state of the main body 4.
　把持部８を把持して本体部４が後方に傾斜した傾斜状態になると、ステップ＃４０で電動送風機３が駆動される。これにより、把持部８を前後方向に移動操作することによって本体部４と一体の吸込口体５が前後に移動して床面の掃除が開始される。この時、電動送風機３の回転数は予め設定した回転数にしてもよく、前回電動送風機３を駆動したときの回転数にしてもよい。 When the grip portion 8 is gripped and the main body portion 4 is tilted backward, the electric blower 3 is driven in step # 40. Accordingly, by moving the gripping portion 8 in the front-rear direction, the suction port body 5 integrated with the main body portion 4 moves back and forth, and cleaning of the floor surface is started. At this time, the rotation speed of the electric blower 3 may be set to a preset rotation speed, or may be the rotation speed when the previous electric blower 3 was driven.
　ステップ＃４１では加速度センサ１６の検知によって本体部４が接地されたか否かが判断される。本体部４が接地された場合はステップ＃４４に移行して電動送風機３が停止される。この時、使用者の意図に反した一瞬の動作によって接地状態が検知されないように、接地状態が所定時間（例えば、２秒）継続したときにステップ＃４４に移行させている。そして、ステップ＃３１に戻り、直立待機状態に移行する。 In step # 41, it is determined whether or not the main body 4 is grounded by the detection of the acceleration sensor 16. When the main-body part 4 is earth | grounded, it transfers to step # 44 and the electric blower 3 is stopped. At this time, when the grounding state continues for a predetermined time (for example, 2 seconds), the process proceeds to step # 44 so that the grounding state is not detected by an instantaneous operation contrary to the user's intention. And it returns to step # 31 and transfers to an erect standby state.
　ステップ＃４２では加速度センサ１６の検知によって本体部４が直立したか否かが判断される。本体部４が直立していない場合はステップ＃４１に戻り、ステップ＃４１、＃４２が繰り返し行われる。 In step # 42, it is determined whether or not the main body 4 is upright by detection of the acceleration sensor 16. If the main body 4 is not upright, the process returns to step # 41, and steps # 41 and # 42 are repeated.
　本体部４の直立状態を加速度センサ１６により検知すると、ステップ＃４３に移行して電動送風機３が停止される。この時、使用者の意図に反した一瞬の動作によって直立状態が検知されないように、直立状態が所定時間（例えば、１秒）継続したときにステップ＃４３に移行させている。そして、ステップ＃３３に戻り、傾斜待機状態に移行する。 When the upright state of the main body 4 is detected by the acceleration sensor 16, the process proceeds to step # 43 and the electric blower 3 is stopped. At this time, when the upright state continues for a predetermined time (for example, 1 second), the process proceeds to step # 43 so that the upright state is not detected by an instantaneous operation contrary to the user's intention. And it returns to step # 33 and transfers to a tilt standby state.
　尚、スタンバイモード時に操作部１３の操作ボタンが操作されるとスタンバイモードを抜け出て通常モードに移行する。これにより、操作ボタンの押下によって電動送風機３の駆動及び停止が行われる。 When the operation button on the operation unit 13 is operated in the standby mode, the standby mode is exited and the normal mode is entered. Thereby, the electric blower 3 is driven and stopped by pressing the operation button.
　図９はステップ＃３９、＃４２の加速度センサ１６による検知結果を示す図である。縦軸は加速度センサ１６の前後方向の出力を示し、横軸は時間を示している。前後方向に本体部４が傾斜してステップ＃４０により時刻ｔ１で電動送風機６が駆動される。また、本体部４が直立してステップ＃４３により時刻ｔ２で電動送風機６が停止されている。 FIG. 9 is a diagram showing the detection results by the acceleration sensor 16 in steps # 39 and # 42. The vertical axis represents the output in the front-rear direction of the acceleration sensor 16, and the horizontal axis represents time. The main body 4 is inclined in the front-rear direction, and the electric blower 6 is driven at time t1 in step # 40. Moreover, the main-body part 4 stands upright and the electric blower 6 is stopped by time # 2 by step # 43.
　同図によると、電動送風機６の駆動時に本体部４に加速度が加わり、加速度センサ１６の出力が異常値を検出する。このため、本体部４が傾斜して電動送風機６を駆動した直後に加速度センサ１６の出力が変化して本体部４が直立したと判断される虞がある。 According to the figure, acceleration is applied to the main body 4 when the electric blower 6 is driven, and the output of the acceleration sensor 16 detects an abnormal value. For this reason, immediately after the main body 4 is inclined and the electric blower 6 is driven, the output of the acceleration sensor 16 may change and it may be determined that the main body 4 is upright.
　従って、電動送風機６を駆動した際に、所定の時間Δｔ（例えば、０．３秒）だけ加速度センサ１６による検知結果に基づく電動送風機６の停止を禁止している。即ち、時間Δｔの期間は加速度センサ１６の検知結果を無視するか、加速度センサ１６の検知を停止する。これにより、加速度センサ１６の誤検知による電動送風機３の停止を防止することができる。 Therefore, when the electric blower 6 is driven, the electric blower 6 is prohibited from being stopped based on the detection result by the acceleration sensor 16 for a predetermined time Δt (for example, 0.3 seconds). That is, during the period of time Δt, the detection result of the acceleration sensor 16 is ignored or the detection of the acceleration sensor 16 is stopped. Thereby, stop of the electric blower 3 due to erroneous detection of the acceleration sensor 16 can be prevented.
　本実施形態によると、加速度センサ１６の検知によって本体部４が直立した際に電動送風機３を停止し、本体部４が直立状態から所定方向に傾斜した際に電動送風機３を駆動したので、掃除の開始及び終了時に使用者は操作を行う必要がなく電気掃除機１の利便性を向上することができる。 According to the present embodiment, the electric blower 3 is stopped when the main body portion 4 stands upright by detection of the acceleration sensor 16, and the electric blower 3 is driven when the main body portion 4 tilts in a predetermined direction from the upright state. At the start and end of the operation, the user does not need to perform an operation, and the convenience of the vacuum cleaner 1 can be improved.
　また、本体部４が接地した際に電動送風機３を停止したので、把持部８から手を離して放置すると電動送風機３を停止して省電力化を図ることができる。また、一の加速度センサ１６によって本体部４の直立状態、傾斜状態及び接地状態を検知するので、多数の検知スイッチを設ける必要がなく、部品点数を削減して電気掃除機１のコストを削減することができる。 Moreover, since the electric blower 3 is stopped when the main body 4 is grounded, the electric blower 3 can be stopped and power saving can be achieved by leaving the hand away from the gripping portion 8. Moreover, since the upright state, the inclined state, and the grounding state of the main body 4 are detected by the single acceleration sensor 16, it is not necessary to provide a large number of detection switches, and the number of parts is reduced, thereby reducing the cost of the vacuum cleaner 1. be able to.
　また、ステップ＃３５、＃３６で延長パイプ６を取り外した際に加速度センサ１６の検知結果に拘わらず電動送風機６を駆動したので、本体部４を直立した状態でも天井面等の掃除を行うことができる。尚、把持部８の装着状態を検知するスイッチを設け、本体部４に装着された延長パイプ６から把持部８を取り外した際に加速度センサ１６の検知結果に拘わらず電動送風機６を駆動してもよい。 Further, when the extension pipe 6 is removed in steps # 35 and # 36, the electric blower 6 is driven regardless of the detection result of the acceleration sensor 16, so that the ceiling surface and the like are cleaned even when the main body 4 is upright. Can do. It should be noted that a switch for detecting the mounting state of the grip portion 8 is provided, and the electric blower 6 is driven regardless of the detection result of the acceleration sensor 16 when the grip portion 8 is removed from the extension pipe 6 mounted on the main body portion 4. Also good.
　また、操作部１３の操作によってスタンバイモードに移行した際に、加速度センサ１６の検知結果に基づいて電動送風機３を駆動するので、スタンバイモードから抜け出ると加速度センサ１６の検知結果に基づいた電動送風機３の駆動が行われない。従って、本体部４の姿勢に応じて電動送風機３を駆動するか否かを使用者により選択することができ、電気掃除機１の利便性をより向上することができる。 Further, when the operation mode is changed to the standby mode by operating the operation unit 13, the electric blower 3 is driven based on the detection result of the acceleration sensor 16. Therefore, when the electric blower 3 exits from the standby mode, the electric blower 3 based on the detection result of the acceleration sensor 16. Is not driven. Therefore, the user can select whether or not to drive the electric blower 3 according to the posture of the main body 4, and the convenience of the vacuum cleaner 1 can be further improved.
　また、電動送風機３の駆動開始から所定期間（Δｔ）は加速度センサ１６の検知結果に基づく電動送風機３の停止を禁止したので、加速度センサ１６の誤検知による電動送風機３の停止を防止することができる。従って、電気掃除機１の利便性をより向上することができる。 Moreover, since the stop of the electric blower 3 based on the detection result of the acceleration sensor 16 is prohibited for a predetermined period (Δt) from the start of the driving of the electric blower 3, the stop of the electric blower 3 due to erroneous detection of the acceleration sensor 16 can be prevented. it can. Therefore, the convenience of the vacuum cleaner 1 can be further improved.
　本実施形態において、所定の操作によってスタンバイモード時に電動送風機３の出力を可変できるようにしてもよい。この時、電動送風機３の出力を可変してから所定期間は加速度センサ１６の検知結果に基づく電動送風機３の停止を禁止するとよい。これにより、電動送風機３の出力が変化した際に加速度センサ１６の誤検知による電動送風機３の停止を防止することができる。 In the present embodiment, the output of the electric blower 3 may be variable in the standby mode by a predetermined operation. At this time, it is preferable to prohibit the stop of the electric blower 3 based on the detection result of the acceleration sensor 16 for a predetermined period after changing the output of the electric blower 3. Thereby, when the output of the electric blower 3 changes, the electric blower 3 can be prevented from being stopped due to erroneous detection of the acceleration sensor 16.
　次に、第２実施形態の電気掃除機について説明する。本実施形態は前述の図１～図２に示す第１実施形態の電気掃除機１と同様に構成され、スタンバイモードの動作が第１実施形態と異なっている。また、延長パイプ６が取り外されると、スタンバイモードから抜け出るようになっている。その他の部分は第１実施形態と同様である。 Next, the vacuum cleaner according to the second embodiment will be described. This embodiment is configured in the same manner as the electric vacuum cleaner 1 of the first embodiment shown in FIGS. 1 and 2, and the operation in the standby mode is different from that of the first embodiment. Further, when the extension pipe 6 is removed, the standby mode is exited. Other parts are the same as those in the first embodiment.
　尚、把持部８は延長パイプ６を介して本体部４に連結され、把持部８の移動に応じて本体部４が移動する。このため、本体部４に設けた加速度センサ１６によって把持部８の加速度を検出することができる。把持部８が急激に移動すると、加速度センサ１６で検知される加速度が通常の掃除時よりも大きくなる。本実施形態では、急激に把持部８を左右に揺動して加速度センサ１６で検知される左右方向の加速度が所定値を超えた際に電動送風機３の出力を可変するようになっている。 The grip 8 is connected to the main body 4 via the extension pipe 6, and the main body 4 moves according to the movement of the grip 8. For this reason, the acceleration of the grip 8 can be detected by the acceleration sensor 16 provided in the main body 4. When the grip portion 8 moves suddenly, the acceleration detected by the acceleration sensor 16 becomes larger than that during normal cleaning. In the present embodiment, the output of the electric blower 3 is varied when the left-right acceleration detected by the acceleration sensor 16 exceeds the predetermined value by rapidly swinging the grip portion 8 to the left and right.
　図１０は本実施形態の電気掃除機１のスタンバイモードの動作を示すフローチャートである。ステップ＃５１、＃５２は本体部４の直立を待機する直立待機状態になっている。ステップ＃５１は直立待機状態に移行してから所定時間（ここでは、１０秒）が経過したか否かが判断される。直立待機状態に移行してから所定時間が経過した場合は図７のフローチャートに戻る。 FIG. 10 is a flowchart showing the operation in the standby mode of the vacuum cleaner 1 of the present embodiment. Steps # 51 and # 52 are in an upright standby state in which the main body 4 is on standby. In step # 51, it is determined whether or not a predetermined time (here, 10 seconds) has elapsed since the transition to the upright standby state. When a predetermined time has elapsed since the transition to the upright standby state, the flow returns to the flowchart of FIG.
　直立待機状態に移行してから所定時間が経過していない場合はステップ＃５２に移行する。ステップ＃５２では加速度センサ１６の検知によって本体部４が直立したか否かが判断される。本体部４が直立していない場合はステップ＃５１に戻り、ステップ＃５１、＃５２が繰り返し行われて本体部４の直立状態を待機する。 If the predetermined time has not elapsed since the transition to the upright standby state, the process proceeds to step # 52. In step # 52, it is determined whether or not the main body 4 is upright by detection of the acceleration sensor 16. If the main body 4 is not upright, the process returns to step # 51, and steps # 51 and # 52 are repeatedly performed to wait for the upright state of the main body 4.
　直立待機状態から本体部４の直立状態を加速度センサ１６により検知すると、ステップ＃５３に移行する。この時、使用者の意図に反した一瞬の動作によって直立状態が検知されないように、直立状態が所定時間（例えば、０．５秒）継続したときにステップ＃５３に移行させている。 When the upright state of the main body 4 is detected by the acceleration sensor 16 from the upright standby state, the process proceeds to step # 53. At this time, when the upright state continues for a predetermined time (for example, 0.5 seconds), the process proceeds to step # 53 so that the upright state is not detected by an instantaneous operation contrary to the user's intention.
　ステップ＃５３～＃５５は本体部４の傾斜を待機する傾斜待機状態になっている。ステップ＃５３では傾斜待機状態に移行してから所定時間（ここでは、１分）が経過したか否かが判断される。傾斜待機状態に移行してから所定時間が経過した場合は図７のフローチャートに戻る。 Steps # 53 to # 55 are in a stand-by state for waiting for the tilt of the main body 4. In step # 53, it is determined whether or not a predetermined time (in this case, 1 minute) has elapsed since the transition to the tilt standby state. When a predetermined time has elapsed since the transition to the tilt standby state, the flow returns to the flowchart of FIG.
　傾斜待機状態に移行してから所定時間が経過していない場合はステップ＃５４に移行する。ステップ＃５４では加速度センサ１６の検知によって本体部４が接地されたか否かが判断される。本体部４が接地された場合はステップ＃５１に戻り、直立待機状態に移行する。この時、使用者の意図に反した一瞬の動作によって接地状態が検知されないように、接地状態が所定時間（例えば、２秒）継続したときにステップ＃５１に移行させている。 If the predetermined time has not elapsed since the transition to the tilt standby state, the process proceeds to step # 54. In step # 54, it is determined whether or not the main body 4 is grounded by the detection of the acceleration sensor 16. When the main body 4 is grounded, the process returns to step # 51 and shifts to an upright standby state. At this time, when the grounding state continues for a predetermined time (for example, 2 seconds), the process proceeds to step # 51 so that the grounding state is not detected by an instantaneous operation contrary to the user's intention.
　本体部４が接地されていない場合はステップ＃５５に移行する。ステップ＃５５では加速度センサ１６の検知によって本体部４が傾斜したか否かが判断される。本体部４が傾斜していない場合はステップ＃５３に戻り、ステップ＃５３～＃５５が繰り返し行われて本体部４の傾斜状態を待機する。 If the main unit 4 is not grounded, the process proceeds to step # 55. In step # 55, it is determined whether or not the main body 4 is tilted by the detection of the acceleration sensor 16. If the main body 4 is not tilted, the process returns to step # 53, and steps # 53 to # 55 are repeated to wait for the tilted state of the main body 4.
　把持部８を把持して本体部４が後方に傾斜した傾斜状態になると、ステップ＃５６で電動送風機３が「弱」ボタンの押下時の出力で駆動される。これにより、把持部８を前後方向に移動操作することによって本体部４と一体の吸込口体５が前後に移動して床面の掃除が開始される。 When the gripping portion 8 is gripped and the main body portion 4 is tilted backward, the electric blower 3 is driven with an output when the “weak” button is pressed in step # 56. Accordingly, by moving the gripping portion 8 in the front-rear direction, the suction port body 5 integrated with the main body portion 4 moves back and forth, and cleaning of the floor surface is started.
　ステップ＃５７では加速度センサ１６の検知によって本体部４が接地されたか否かが判断される。本体部４が接地された場合はステップ＃６４に移行して電動送風機３が停止される。この時、使用者の意図に反した一瞬の動作によって接地状態が検知されないように、接地状態が所定時間（例えば、２秒）継続したときにステップ＃６４に移行させている。そして、ステップ＃５１に戻り、直立待機状態に移行する。 In step # 57, it is determined whether or not the main body 4 is grounded by the detection of the acceleration sensor 16. When the main-body part 4 is earth | grounded, it transfers to step # 64 and the electric blower 3 is stopped. At this time, the process proceeds to step # 64 when the grounding state continues for a predetermined time (for example, 2 seconds) so that the grounding state is not detected by a momentary operation contrary to the user's intention. And it returns to step # 51 and transfers to an erect standby state.
　本体部４が接地されていない場合はステップ＃５８で本体部４が左右方向に揺動したか否かが判断される。加速度センサ１６の検知による本体部４の左右方向の加速度が所定値を超えると、把持部８の急激な揺動により本体部４が揺動したと判断してステップ＃５９に移行する。本体部４が左右方向に揺動していないと判断した場合はステップ＃６２に移行する。 If the main unit 4 is not grounded, it is determined in step # 58 whether the main unit 4 has swung in the left-right direction. If the acceleration in the left-right direction of the main body 4 detected by the acceleration sensor 16 exceeds a predetermined value, it is determined that the main body 4 has been swung due to the sudden swing of the grip 8 and the process proceeds to step # 59. If it is determined that the main body 4 is not swinging left and right, the process proceeds to step # 62.
　ステップ＃５９では電動送風機３の出力が増加され、「強」ボタンの押下時の出力で電動送風機３が駆動される。これにより、使用者は操作部１３の操作ボタンを押下する必要がなく、把持部８を揺動させるだけで電動送風機３の出力を可変することができる。 In step # 59, the output of the electric blower 3 is increased, and the electric blower 3 is driven by the output when the “strong” button is pressed. Thereby, the user does not need to press the operation button of the operation unit 13 and can change the output of the electric blower 3 only by swinging the gripping unit 8.
　ステップ＃６０では電動送風機３の出力を増加してから所定時間が経過するまで待機する。所定時間が経過すると、ステップ＃６１で電動送風機３が「弱」ボタンの押下時の出力で駆動される。これにより、被掃除面に応じて強力に塵埃を吸い込んで掃除を行う場合や、電力消費を抑制して弱い吸引力で掃除を行う場合等を使い分けることができる。 In step # 60, after the output of the electric blower 3 is increased, the process waits until a predetermined time elapses. When the predetermined time has elapsed, in step # 61, the electric blower 3 is driven with an output when the “weak” button is pressed. Thereby, it is possible to properly use the case where the dust is strongly sucked in accordance with the surface to be cleaned and the case where the cleaning is performed with a weak suction force while suppressing the power consumption.
　尚、ステップ＃６０で所定時間が経過した際にステップ＃６１で電動送風機３の出力を低下させているが、再度左右方向に把持部８を揺動した際に電動送風機３の出力を低下させてもよい。また、把持部８を左右方向に揺動すると電動送風機３の出力を増加し、上下方向に揺動すると電動送風機３の出力を低下させてもよい。この時、加速度センサ１６の検知による本体部４の左右方向や上下方向の加速度が所定値を超えると、把持部８の急激な揺動により本体部４が揺動したと判断して電動送風機３の出力が可変される。 The output of the electric blower 3 is reduced in step # 61 when a predetermined time has elapsed in step # 60, but the output of the electric blower 3 is reduced when the gripping portion 8 is swung again in the left-right direction. May be. Further, the output of the electric blower 3 may be increased when the gripping portion 8 is swung in the left-right direction, and the output of the electric blower 3 may be decreased when the holding portion 8 is swung in the vertical direction. At this time, when the acceleration in the horizontal direction or the vertical direction of the main body 4 detected by the acceleration sensor 16 exceeds a predetermined value, it is determined that the main body 4 has been swung due to the sudden swing of the grip 8 and the electric blower 3 The output of is variable.
　また、把持部８を把持した手を一方向（例えば、右回り）に回転したときに電動送風機３の出力を増加し、他方向（例えば、左回り）に回転したときに電動送風機３の出力を低下させてもよい。この時、加速度センサ１６の検知による本体部４の左右方向、上下方向及び前後方向の加速度の合成値が所定値を超えると、把持部８の急激な回転により本体部４が回転したと判断して電動送風機３の出力が可変される。 Further, the output of the electric blower 3 is increased when the hand holding the gripping portion 8 is rotated in one direction (for example, clockwise), and the output of the electric blower 3 is rotated in the other direction (for example, counterclockwise). May be reduced. At this time, if the combined value of the acceleration in the left-right direction, the up-down direction, and the front-rear direction of the main body portion 4 detected by the acceleration sensor 16 exceeds a predetermined value, it is determined that the main body portion 4 has rotated due to the sudden rotation of the grip portion 8. Thus, the output of the electric blower 3 is varied.
　ステップ＃６２では加速度センサ１６の検知によって本体部４が直立したか否かが判断される。本体部４が直立していない場合はステップ＃５７に戻り、ステップ＃５７～＃６２が繰り返し行われる。 In step # 62, it is determined whether or not the main body 4 is upright by detection of the acceleration sensor 16. If the main body 4 is not upright, the process returns to step # 57, and steps # 57 to # 62 are repeated.
　本体部４の直立状態を加速度センサ１６により検知すると、ステップ＃６３に移行して電動送風機３が停止される。この時、使用者の意図に反した一瞬の動作によって直立状態が検知されないように、直立状態が所定時間（例えば、１秒）継続したときにステップ＃６３に移行させている。そして、ステップ＃５３に戻り、傾斜待機状態に移行する。 When the upright state of the main body 4 is detected by the acceleration sensor 16, the process proceeds to step # 63 and the electric blower 3 is stopped. At this time, when the upright state continues for a predetermined time (for example, 1 second), the process proceeds to step # 63 so that the upright state is not detected by an instantaneous operation contrary to the user's intention. And it returns to step # 53 and transfers to a tilt standby state.
　尚、スタンバイモード時に操作部１３の操作ボタンが操作されるとスタンバイモードを抜け出て通常モードに移行する。これにより、操作ボタンの押下によって電動送風機３の駆動及び停止が行われる。 When the operation button on the operation unit 13 is operated in the standby mode, the standby mode is exited and the normal mode is entered. Thereby, the electric blower 3 is driven and stopped by pressing the operation button.
　また、第１実施形態と同様に、ステップ＃５６で電動送風機６を駆動した際に、所定の時間Δｔ（図９参照）だけ加速度センサ１６による検知結果に基づく電動送風機６の停止が禁止される。ステップ＃５９、＃６１でも同様に、電動送風機３の出力を可変してから所定期間は加速度センサ１６の検知結果に基づく電動送風機３の停止及び出力の可変が禁止される。これにより、電動送風機３の出力が変化した際に加速度センサ１６の誤検知による電動送風機３の停止や連続した出力の可変を防止することができる。 Similarly to the first embodiment, when the electric blower 6 is driven in step # 56, the stop of the electric blower 6 based on the detection result by the acceleration sensor 16 is prohibited for a predetermined time Δt (see FIG. 9). . Similarly, in steps # 59 and # 61, after the output of the electric blower 3 is changed, the stop of the electric blower 3 and the change of the output based on the detection result of the acceleration sensor 16 are prohibited for a predetermined period. Thereby, when the output of the electric blower 3 is changed, it is possible to prevent the electric blower 3 from being stopped due to erroneous detection of the acceleration sensor 16 and the continuous output from being changed.
　本実施形態によると、把持部８が所定の方向に所定値を超える加速度で移動したことを加速度センサ１６により検知した際に、電動送風機３の出力を可変したので、把持部８の近傍に多数の操作ボタンを設ける必要がなく、容易に電動送風機３の出力を変えることができる。また、使用者の目が不自由であっても操作ボタンの操作を必要とせず容易に電動送風機３の出力を変えることができる。従って、電気掃除機１の利便性を向上することができる。 According to the present embodiment, since the output of the electric blower 3 is varied when the acceleration sensor 16 detects that the grip portion 8 has moved in a predetermined direction with an acceleration exceeding a predetermined value, there are many in the vicinity of the grip portion 8. It is not necessary to provide an operation button, and the output of the electric blower 3 can be easily changed. Moreover, even if a user's eyes are inconvenient, operation of an operation button is not required and the output of the electric blower 3 can be changed easily.

　また、吸込口体５が本体部４の下方に回動自在に設けられ、把持部８が本体部４を介して吸込口体５に連結された縦型の電気掃除機１であるので、電動送風機３の出力を可変する際に手元から離れた本体部４の操作部１３を操作する必要がない。従って、電気掃除機１の利便性を向上することができる。 Moreover, since the suction port body 5 is provided in the lower part of the main body part 4 so as to be freely rotatable and the gripping part 8 is a vertical electric vacuum cleaner 1 connected to the suction port body 5 via the main body part 4, When changing the output of the blower 3, it is not necessary to operate the operation part 13 of the main-body part 4 away from the hand. Therefore, the convenience of the vacuum cleaner 1 can be improved.
　また、加速度センサ１６の検知によって本体部４が直立した際に電動送風機３を停止し、本体部４が直立状態から所定方向に傾斜した際に電動送風機３を駆動したので、掃除の開始及び終了時に使用者は操作を行う必要がなく電気掃除機１の利便性を向上することができる。加えて、一の加速度センサ１６によって本体部４の姿勢を検知するとともに把持部８の移動を検知するので、多数の検知スイッチを設ける必要がなく、部品点数を削減して電気掃除機１のコストを削減することができる。 Moreover, since the electric blower 3 was stopped when the main body part 4 was upright by detection of the acceleration sensor 16 and the main body part 4 was tilted in the predetermined direction from the upright state, the cleaning start and end Sometimes the user does not need to perform an operation, and the convenience of the vacuum cleaner 1 can be improved.
