しかしながら、前記従来の構成においては、吸込み力が一定であるため塵埃が取れやすい木床などでは吸込み力を落とし、消費電力を抑え、ゴミが取れにくいじゅうたんでは吸込み力を上げて取れ性を向上させる動作を使用者が手元操作部で選択して行っていた。また、電動機も負荷が軽い木床での塵埃の吹き飛ばしがなく、じゅうたんでは塵埃がかきだせる回転数の設定や、操作性を考えた吸込み具の高さの設定など、床面は多仕様あるにもかかわらず回転数や吸込み具の高さなどが一定であるために両立できる設定を行うのは難しいものがあった。またペット毛等がじゅうたんに入り込んだ場合には現在の設定では集塵できにくいという不具合があった。   However, in the conventional configuration, since the suction force is constant, the suction force is reduced on wooden floors where dust is easily removed, reducing power consumption, and for carpets that are difficult to remove dust, the suction force is increased to improve the take-off performance. The operation was selected by the user using the local operation unit. Also, the electric motor does not blow off dust on a light wooden floor, and the floor has many specifications such as setting the rotation speed at which dust can be scraped out and setting the height of the suction tool considering operability. Nevertheless, since the rotation speed and the height of the suction tool are constant, it is difficult to make compatible settings. In addition, when pet hair or the like gets into the carpet, there is a problem that it is difficult to collect dust with the current setting.

本発明は、前記従来の課題を解決するもので、塵埃の取れにくい場所を集中して掃除を行う場合に集塵効率を向上させる掃除性能を高めた電気掃除機を提供するものである。   The present invention solves the above-mentioned conventional problems, and provides a vacuum cleaner with improved cleaning performance that improves dust collection efficiency when cleaning is performed in a concentrated area where dust is difficult to remove.

前記従来の課題を解決するために、本発明の電気掃除機は、吸込み具の往復速度を検出する往復検出手段と、吸込み力を発生させる電動送風機を備え、前記往復検出手段の速度が予め設定している速度よりも速くなったときは前記電動送風機の吸込み力を向上させることとしたものである。   In order to solve the above-described conventional problems, the vacuum cleaner of the present invention includes a reciprocating detection means for detecting the reciprocating speed of the suction tool and an electric blower for generating a suction force, and the speed of the reciprocating detection means is preset. When the speed is higher than the current speed, the suction force of the electric blower is improved.

これによってじゅうたんなどの塵埃が取れにくい場所を集中的に掃除を行う際に、複数回同じ場所を速い往復速度で吸込み具を操作した場合に吸込み力が上がる。   As a result, when intensively cleaning a place such as a carpet where dust is difficult to remove, the suction force increases when the suction tool is operated at the same reciprocating speed at the same place multiple times.

本発明の電気掃除機は、塵埃が取れにくい場所を集中的に掃除を行う際に、吸込み力が上がるため取れにくい塵埃を集塵することができる。また通常時の往復速度では吸込み力が低いため消費電力を抑え、かつ騒音も抑制することができる。   The vacuum cleaner of the present invention can collect dust that is difficult to remove because the suction force increases when intensively cleaning a place where dust is difficult to remove. Further, since the suction force is low at the normal reciprocating speed, power consumption can be suppressed and noise can also be suppressed.

第1の発明は吸込み具の往復速度を検出する往復検出手段と、吸込み力を発生させる電動送風機を備え、前記往復検出手段の速度が予め設定している速度よりも速くなったときは前記電動送風機の吸込み力を向上させることにより、塵埃が取れにくい場所を集中的に掃除を行う際に、吸込み力が上がるため取れにくい塵埃を集塵することができる。また通常時の往復速度では吸込み力が低いため消費電力を抑え、かつ騒音も抑制することができる。   A first invention includes a reciprocation detecting means for detecting a reciprocating speed of the suction tool and an electric blower for generating a suction force. When the speed of the reciprocating detection means becomes higher than a preset speed, the electric motor By improving the suction force of the blower, dust that is difficult to remove can be collected because the suction force increases when the place where dust is difficult to remove is intensively cleaned. Further, since the suction force is low at the normal reciprocating speed, power consumption can be suppressed and noise can also be suppressed.

第2の発明は、吸込み具の往復速度を検出する往復検出手段と、吸込み具に塵埃をかきあげるための回転ブラシと、前記回転ブラシを回転させる電動機を備え、前記往復検出手段の速度が予め設定している速度よりも速くなったときは前記電動機の回転数を向上させることにより、塵埃が取れにくい場所を集中的に掃除を行う際に、電動機の回転数が上がり回転ブラシの塵埃のかきあげ力が上がるため取れにくい塵埃を集塵することができる。また通常時の往復速度では回転数が消費電力を抑え、かつ塵埃の吹き飛ばしも抑えることができる。   The second invention comprises a reciprocating detection means for detecting the reciprocating speed of the suction tool, a rotating brush for scraping dust to the suction tool, and an electric motor for rotating the rotating brush, and the speed of the reciprocating detecting means is preset. When the speed is higher than the speed at which the motor is rotating, the rotational speed of the motor is increased so that when the dust is difficult to remove, the motor speed increases and the dust of the rotating brush is lifted up. Can collect dust that is difficult to remove. Further, at the normal reciprocating speed, the number of rotations can reduce power consumption, and dust can be prevented from being blown off.

第3の発明は、吸込み具の往復速度を検出する往復検出手段と、吸込み具に塵埃をかきあげるための回転ブラシと、前記回転ブラシの床面からの高さを可変できるブラシ移動手段を備え、前記往復検出手段の速度が予め設定している速度よりも速くなったときは前記回転ブラシを床面に近づけることにより、塵埃が取れにくい場所を集中的に掃除を行う際に、回転ブラシが吸込み具から近づき、かきあげ力が上がるため取れにくい塵埃を集塵することができる。また通常時の往復速度では回転ブラシは吸込み具に収納されているため床の傷つきも抑制できる。   The third invention comprises a reciprocating detection means for detecting the reciprocating speed of the suction tool, a rotating brush for scraping dust to the suction tool, and a brush moving means capable of changing the height of the rotating brush from the floor surface, When the speed of the reciprocating detection means is higher than a preset speed, the rotary brush sucks in when intensively cleaning the place where dust is difficult to remove by bringing the rotary brush close to the floor surface. It is possible to collect dust that is difficult to remove because it gets closer to the tool and the lifting force increases. Further, since the rotating brush is housed in the suction tool at the normal reciprocating speed, it is possible to suppress damage to the floor.

第4の発明は、吸込み具の往復速度を検出する往復検出手段と、吸込み具の床面からの高さを可変できるノズル移動手段を備え、前記往復検出手段の速度が予め設定している速度よりも速くなったときは前記吸込み具を床面に近づけることにより、塵埃が取れにくい場所を集中的に掃除を行う際に、吸込み具が床面に近づき、床面との負圧があがるため取れにくい塵埃を集塵することができる。また通常時の往復速度では吸込み具は床面から離れているため、操作性の軽減もできる。   4th invention is equipped with the reciprocating detection means which detects the reciprocating speed of a suction tool, and the nozzle movement means which can vary the height from the floor surface of a suction tool, The speed of the said reciprocation detecting means is preset. When the speed becomes faster, the suction tool gets closer to the floor when intensive cleaning is performed in a place where it is difficult to remove dust. Dust that is difficult to remove can be collected. Moreover, since the suction tool is separated from the floor surface at the normal reciprocating speed, the operability can be reduced.

第5の発明は、特に、第1〜4の発明のいずれか1つの発明の往復検出手段で、吸込み具に備えた加速度センサの加速度変化によって判断することにより、木床および畳等の電流負荷変化の小さな床面においても往復速度の検出ができ、すべての床面おいて確実に対応できる。   The fifth invention is particularly a reciprocation detecting means according to any one of the first to fourth inventions, and the current load such as a wooden floor and a tatami mat is judged by judging the acceleration change of the acceleration sensor provided in the suction tool. The reciprocating speed can be detected even on a floor surface with small changes, and all floor surfaces can be handled reliably.

Reference numeral 16 denotes a commercial power source for supplying power to the vacuum cleaner.

以上のように構成された電気掃除機について、以下その動作、作用を説明する。   About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

手元操作部4には、図1に示すように複数のスイッチSW1〜SW3と、抵抗r1〜r4が内蔵されており、本体1側の回路に内蔵された抵抗Rとの分割電圧の変化によって手元操作がどのように行われているか認識し、第1の双方向性サイリスタ10および第2の双方向性サイリスタ13にマイクロコンピュータ14信号が出力され、電動送風機2および電動機8を手元操作に応じた吸い込み力で動作を行う。電動機8が動作を行い、負荷電流が流れるとホース3の配線上の微小抵抗rに電流Iが流れるため、抵抗rでr×Iの電圧ロスが発生し、マイクロコンピュータ14にはこの電圧ロスを含んで抵抗分割された図3に示すような波形にて入力される。この波形の波高値は負荷電流Iの変化によって変化し、電流Iが大きくなれば高くなり、小さくなれば低くなるのでマイクロコンピュータ14は、電動機8の負荷電流を判断することができることになる。   As shown in FIG. 1, the hand operating unit 4 includes a plurality of switches SW1 to SW3 and resistors r1 to r4, and the hand operating unit 4 is controlled by a change in the divided voltage with the resistor R built in the circuit on the main body 1 side. Recognizing how the operation is performed, the microcomputer 14 signal is output to the first bidirectional thyristor 10 and the second bidirectional thyristor 13, and the electric blower 2 and the electric motor 8 are operated according to the hand operation. Operates with suction force. When the electric motor 8 operates and a load current flows, the current I flows through the minute resistance r on the wiring of the hose 3, so that a voltage loss of r × I occurs at the resistance r, and this voltage loss is transmitted to the microcomputer 14. It is input in a waveform as shown in FIG. The peak value of this waveform changes according to the change of the load current I, and increases as the current I increases, and decreases as the current I decreases. Therefore, the microcomputer 14 can determine the load current of the motor 8.

また図3の波形からも明らかなように第1の双方向性サイリスタ10が導通してから電圧の波高値は一定時間後になっており、そのときの変化が大きくなるため、そのタイミングにあわせて取り込むと精度が向上することは言うまでもない。またこの波形を平滑し、増幅し取り込むことでも精度の向上は行える。ここで回転ブラシ7は一方向に回転しているため、吸込み具6を押し出している場合は、被掃除面に吸込み具6が押し付けている状態となり、また引いている場合は、被掃除面に吸込み具6が離れようとする状態となるため、押し出している状態の方が引いている状態よりも電動機8の負荷電流Iは大きくなる。つまり、使用者の吸込み具6の往復操作による負荷電流Iが変動するため、あるタイミングの電圧または平滑した電圧は図4に示すように波を打ったように変化する。この波形の変化幅および絶対値は負荷電流Iによって変わるため木床やじゅうたんなどの被掃除面の負荷によって異なる。またこの波形の波長は往復速度によって異なってくる。   Further, as apparent from the waveform of FIG. 3, the peak value of the voltage is after a certain time since the first bidirectional thyristor 10 is turned on, and the change at that time becomes large. Needless to say, the accuracy is improved by taking in. The accuracy can also be improved by smoothing, amplifying and capturing this waveform. Here, since the rotating brush 7 is rotating in one direction, when the suction tool 6 is pushed out, the suction tool 6 is pressed against the surface to be cleaned. Since the suction tool 6 is in a state of being separated, the load current I of the electric motor 8 is larger in the pushing state than in the pulling state. That is, since the load current I due to the reciprocating operation of the user's suction tool 6 fluctuates, the voltage at a certain timing or the smoothed voltage changes like a wave as shown in FIG. Since the change width and absolute value of this waveform vary depending on the load current I, it varies depending on the load on the surface to be cleaned such as a wooden floor or a carpet. The wavelength of this waveform varies depending on the reciprocating speed.

よってこの波形によってマイクロコンピュータ14は被掃除面と吸込み具6の往復速度を検出することができる。使用者が塵埃が取れにくく限られた掃除範囲を集中的に掃除を行う際には往復速度は速くなるため、この往復速度をマイクロコンピュータ14が認識し予め決められている速度以上になると、第1の双方向性サイリスタ10の位相値を変化させ、電動機8の回転数を向上させ、さらにかきあげ力を向上させたり、第2の双方向性サイリスタ13の位相値を変化させ、吸込み力の向上をさせ、さらに、報知手段16によって使用者に報知を行うように動作する。また被床面も検出できているため、被床面の種類によって往復速度の速いときの電動送風機2および電動機8の電力制御は多段階で行えば省エネと集塵性能とを両立することができる。往復速度は使用者によって異なるため、記憶手段(図示せず)を用いてこの波形を常時モニターし使用頻度が高い往復速度を記憶し、予めマイクロコンピュータ14にて決めていた速度が速いと認識する速度を補正することによって使用者の実感に合わせこむこともできる。また往復速度によって多段階に電動送風機2および電動機8の電力制御を行えば、さらに省エネと集塵性能とを両立することができることは言うまでもない。   Therefore, the microcomputer 14 can detect the reciprocating speed of the surface to be cleaned and the suction tool 6 by this waveform. When the user intensively cleans the limited cleaning range where dust is difficult to remove, the reciprocation speed increases. When the microcomputer 14 recognizes this reciprocation speed and exceeds the predetermined speed, The phase value of the first bidirectional thyristor 10 is changed to improve the rotational speed of the electric motor 8, and the lifting force is further improved, or the phase value of the second bidirectional thyristor 13 is changed to improve the suction force. In addition, the notification unit 16 operates to notify the user. Further, since the floor surface can also be detected, the power control of the electric blower 2 and the motor 8 when the reciprocating speed is fast depending on the type of the floor surface can achieve both energy saving and dust collection performance if performed in multiple stages. . Since the reciprocating speed varies depending on the user, this waveform is constantly monitored using a storage means (not shown) to store the reciprocating speed having a high use frequency, and it is recognized that the speed determined in advance by the microcomputer 14 is high. It is also possible to adjust to the user's feeling by correcting the speed. Needless to say, if power control of the electric blower 2 and the electric motor 8 is performed in multiple stages according to the reciprocating speed, it is possible to achieve both energy saving and dust collection performance.

本実施の形態は往復検出手段11を電動機8の負荷電流Iの変化で検出することで実現していたが、吸込み具6内に加速度センサ17および加速度センサ17の電源となる第2の直流電源装置18を有することで、往復動作から発生する加速度センサ17内のピエゾ抵抗素子の変化からも吸込み具6の往復速度は検出することができる。また延長管5内に角度センサ19および角度センサ19の電源となる第3の直流電源装置20を有することで、往復動作から発生する延長管5の重力方向からの角度を角度センサ19内の錘が下限であることを基準として角度を光センサで読むことにより検出することでも吸込み具6の往復速度は検出することができる。また電流検出手段12もカレントトランスのような専用部品で検出すればさらに容易に実現できる。   In the present embodiment, the reciprocating detection means 11 is realized by detecting the change in the load current I of the electric motor 8. However, the acceleration sensor 17 and the second DC power source serving as the power source for the acceleration sensor 17 are provided in the suction tool 6. By having the device 18, the reciprocating speed of the suction tool 6 can be detected from the change of the piezoresistive element in the acceleration sensor 17 generated by the reciprocating operation. Further, by providing the extension tube 5 with the angle sensor 19 and the third DC power supply device 20 that serves as a power source for the angle sensor 19, the angle from the gravity direction of the extension tube 5 generated by the reciprocating operation can be determined. The reciprocating speed of the suction tool 6 can also be detected by detecting the angle by reading it with an optical sensor with reference to the lower limit. Further, the current detecting means 12 can be realized more easily if it is detected by a dedicated component such as a current transformer.

以上のように、本実施の形態の形態においては吸込み具6の往復動作による負荷電流Iの変化をホース3の導体抵抗に発生する電圧ロスを検出することで往復速度を検出し、往復速度によって電動送風機2の吸込み力向上および電動機8のかきあげ力の向上を行うことにより、限られた掃除範囲を集中的に掃除を行う際の最適制御が実現でき、集塵性能が向上する使用性の高い電気掃除機を提供することができる。   As described above, in the present embodiment, the reciprocating speed is detected by detecting the voltage loss generated in the conductor resistance of the hose 3 due to the change in the load current I due to the reciprocating operation of the suction tool 6. By improving the suction force of the electric blower 2 and improving the lifting force of the electric motor 8, optimum control when intensively cleaning a limited cleaning range can be realized, and dust collection performance is improved. A vacuum cleaner can be provided.

(実施の形態2)
図5は、本発明の第2の実施の形態における吸込み具の内部構成図を示すものである。
21は吸込み具6の底面に配しているローラである。22は吸込み具6隅に配されているローラ21に連結している移動体であり、この移動体22がノズル移動手段であるステッピングモータ23にギア24を介して連結されている。前記移動体22はステッピングモータ23の正反回転によって吸込み具6の上下方向に移動できるように取り付けてある。
(Embodiment 2)
FIG. 5 shows an internal configuration diagram of the suction tool according to the second embodiment of the present invention.
Reference numeral 21 denotes a roller disposed on the bottom surface of the suction tool 6. Reference numeral 22 denotes a moving body connected to a roller 21 disposed at the corner of the suction tool 6, and this moving body 22 is connected to a stepping motor 23 which is a nozzle moving means via a gear 24. The moving body 22 is attached so that it can move in the vertical direction of the suction tool 6 by forward and reverse rotation of the stepping motor 23.

以上のように構成された電気掃除機について、以下その動作、作用を説明する。   About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

本実施の形態の回路構成で吸込み具6の往復速度を検出し、往復速度が速いときにはマイクロコンピュータ14はノズル移動手段であるステッピングモータ23に正回転方向に回転するように信号を出力し、ステッピングモータ23が正回転することで移動体22は吸込み具6が被掃除面に近づくように動作するため吸込み具6負圧が上がる。往復速度が遅くなったときには逆回転することで吸込み具6は被掃除面から離れるように動作するため負圧が下がる。ここで往復速度が速くなったときには吸込み具6は被床面に近づくため、床面に対する負荷が大きくなり回転ブラシ7の回転数は小さくなるが、負荷電流Iを検出しているため、被掃除面に対してかきあげ力を損なわないように移動距離を可変することは言うまでもない。またこの構成で移動体22を回転ブラシ7に連結させれば、ブラシ移動手段25として回転ブラシ7のみを被掃除面近づけることも行える。   In the circuit configuration of this embodiment, the reciprocating speed of the suction tool 6 is detected, and when the reciprocating speed is high, the microcomputer 14 outputs a signal to the stepping motor 23 that is a nozzle moving means so as to rotate in the forward rotation direction. When the motor 23 rotates forward, the moving body 22 operates so that the suction tool 6 approaches the surface to be cleaned, so that the negative pressure of the suction tool 6 increases. When the reciprocating speed becomes slow, the suction tool 6 moves away from the surface to be cleaned by rotating in reverse, so that the negative pressure decreases. Here, when the reciprocating speed increases, the suction tool 6 approaches the floor surface, so that the load on the floor surface increases and the rotational speed of the rotary brush 7 decreases, but the load current I is detected, so the object to be cleaned is cleaned. It goes without saying that the moving distance is varied so as not to impair the scraping force on the surface. If the moving body 22 is connected to the rotating brush 7 with this configuration, only the rotating brush 7 can be brought close to the surface to be cleaned as the brush moving means 25.

以上のように、本実施の形態の形態においては吸込み具6の往復動作により、往復速度によって吸込み具6や回転ブラシ7を被掃除面に近づかせることで、被床面との負圧を上げたり、回転ブラシ7のかきあげ力を向上させたりすることにより、限られた掃除範囲を集中的に掃除を行う際の最適制御が実現でき集塵性能が向上する使用性の高い電気掃除機を提供することができる。   As described above, in the present embodiment, the negative pressure on the floor surface is increased by moving the suction tool 6 and the rotating brush 7 closer to the surface to be cleaned by the reciprocating speed by the reciprocating operation of the suction tool 6. Provides a highly usable vacuum cleaner that improves dust collection performance by providing optimal control when intensively cleaning a limited cleaning range by improving the lifting force of the rotating brush 7 can do.

以上のように、本発明に係る電気掃除機は、塵埃が取れにくい場所を掃除する際に、吸込み具の往復速度が速くなることを応用して、吸込み力の向上等が自動的に行なえ、様々な床面のその時々の状態に対応できるため、幅広く利用できるものである。   As described above, the vacuum cleaner according to the present invention can automatically improve the suction force by applying the fact that the reciprocating speed of the suction tool increases when cleaning a place where dust is difficult to remove, Since it can respond to the various conditions of various floors, it can be used widely.
