Description

電気掃除機Electric vacuum cleaner
　本発明は、電気掃除機に関するもので、特に、吸引した塵埃を検知する塵埃検知手段を備えた電気掃除機に関するものである。 The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner provided with dust detection means for detecting sucked dust.
　近年、ハウスダストに対する関心が高まってきており、ハウスダストを除去するための商品が数多く販売されている。 In recent years, interest in house dust has increased, and many products for removing house dust have been sold.
　そのなかで、電気掃除機においては、吸込具によって吸引した塵埃を検知する塵埃検知手段を備え、吸引した塵埃量に応じた表示を行うとともに、吸引力の制御を行って塵埃を確実に除去するものがあった（例えば、特許文献１参照）。 Among them, the vacuum cleaner is provided with dust detection means for detecting the dust sucked by the suction tool, and displays according to the sucked dust amount and controls the suction force to reliably remove the dust. There was a thing (for example, refer to patent documents 1).
　また、これらの電気掃除機においては、床面の種類に応じて塵埃検知手段の塵埃検知感度を調整し、床面の種類に応じた最適な感度で塵埃を検知するものがあった（例えば、特許文献２参照）。 In addition, in these vacuum cleaners, there is one that adjusts the dust detection sensitivity of the dust detection means according to the type of the floor surface, and detects dust with the optimum sensitivity according to the type of the floor surface (for example, Patent Document 2).
　しかしながら、上記特許文献１や特許文献２に開示されている電気掃除機では、吸引した塵埃量に応じて表示を行うとともに、吸引力の制御を行っているため、使用者が直接吸込具を動かして塵埃を吸引する方式の電気掃除機の場合、課題を生じる。すなわち、被掃除面の塵埃量が同じであっても使用者の吸込具の動かし方によって塵埃の吸引量が変わってしまうため、表示や吸引力が実際の塵埃量に対応できていないという課題があった。 However, in the vacuum cleaners disclosed in Patent Document 1 and Patent Document 2 described above, display is performed according to the amount of dust sucked and suction force is controlled, so that the user moves the suction tool directly. In the case of a vacuum cleaner that sucks dust, a problem arises. That is, even if the amount of dust on the surface to be cleaned is the same, the amount of dust sucked varies depending on how the user moves the suction tool, so the problem is that the display and suction force cannot correspond to the actual amount of dust. there were.
　例えば、塵埃を吸引するための吸込具を遅く移動させた場合、その分単位時間あたりの掃除面積は狭くなるため塵埃の吸引量も落ちる。また逆に、吸込具を早く移動させた場合は、単位時間あたりの掃除面積は広くなるが、塵埃を被掃除面から吸い取る前に吸込具が移動してしまうため、塵埃が吸いきれず、結果として塵埃の吸引量が落ちてしまう場合があった。このような場合、表示手段で使用者に報知できなかったり、電動送風機の入力を上げる制御ができなかったりするため、塵埃の取り残しが発生してしまうという課題があった。本発明は、上記従来の課題を解決するもので、使用者の掃除の仕方に応じた適切な感度を設定でき、塵埃の取り残しが無いより確実な掃除ができる電気掃除機を提供することを目的とするものである。 For example, when the suction tool for sucking dust is moved slowly, the cleaning area per unit time is reduced accordingly, and the amount of dust sucked is also reduced. Conversely, if the suction tool is moved quickly, the cleaning area per unit time will be large, but the suction tool will move before the dust is sucked from the surface to be cleaned. As a result, the amount of dust sucked may drop. In such a case, the user cannot be notified by the display means, or the control to increase the input of the electric blower cannot be performed, and there is a problem that dust is left behind. The present invention solves the above-described conventional problems, and an object thereof is to provide an electric vacuum cleaner that can set an appropriate sensitivity according to a user's cleaning method and can perform more reliable cleaning without leaving any dust. It is what.

　従来の課題を解決するために本発明の電気掃除機は、吸引風を発生させる電動送風機と、使用者の操作により移動し、電動送風機の吸引風により塵埃を吸引する吸引口と、吸引した塵埃を検知し被掃除面の塵埃量レベルを出力する塵埃検知手段と、塵埃検知手段の塵埃量レベルを補正する補正手段と、掃除中の吸引口の移動速度を検知する速度検知手段とを備える。さらに、補正手段は、速度検知手段が出力する移動速度検知信号に基づき塵埃検知手段の塵埃量レベルを補正するもので、使用者の掃除の仕方に応じた適切な感度を設定でき、塵埃の取り残しが無いより確実な掃除ができる電気掃除機を提供することが可能になる。 In order to solve the conventional problems, an electric vacuum cleaner of the present invention includes an electric blower that generates suction wind, a suction port that is moved by a user's operation and sucks dust by the suction wind of the electric blower, and sucked dust And a dust detecting means for outputting the dust amount level of the surface to be cleaned, a correcting means for correcting the dust amount level of the dust detecting means, and a speed detecting means for detecting the moving speed of the suction port during cleaning. Further, the correction means corrects the dust amount level of the dust detection means based on the moving speed detection signal output from the speed detection means, and can set an appropriate sensitivity according to the user's cleaning method, and leave the dust behind. Therefore, it is possible to provide a vacuum cleaner that can perform more reliable cleaning than there is.

　以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
　（実施の形態１）
　本発明の実施の形態１における電気掃除機について、図１～７を用いて説明する。図１は、本実施の形態における電気掃除機の概略図である。図１に示すように、本体１には吸引風を発生させる電動送風機２が内蔵されている。電動送風機２の吸引風は、ホース４と延長管７を通じて吸引口の一つである吸込具８へ伝わり床面の塵埃を吸引する。本体１とホース４、ホース４と延長管７、延長管７と吸込具８はそれぞれ着脱可能である。ホース４と延長管７との接続部については、延長管７を外してホース４側から塵埃を吸引することができる。また、延長管７と吸込具８の接続部については、吸込具８を外して延長管７側から塵埃を吸引することができる。 (Embodiment 1)
A vacuum cleaner according to Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is a schematic view of a vacuum cleaner in the present embodiment. As shown in FIG. 1, the main body 1 includes an electric blower 2 that generates suction air. The suction air from the electric blower 2 is transmitted to the suction tool 8 which is one of the suction ports through the hose 4 and the extension pipe 7 to suck the dust on the floor surface. The main body 1 and the hose 4, the hose 4 and the extension pipe 7, and the extension pipe 7 and the suction tool 8 are detachable. About the connection part of the hose 4 and the extension pipe | tube 7, the extension pipe | tube 7 can be removed and dust can be attracted | sucked from the hose 4 side. Moreover, about the connection part of the extension pipe 7 and the suction tool 8, the suction tool 8 can be removed and dust can be attracted | sucked from the extension pipe 7 side.
　ホース４と本体１との接続部近傍には、吸引した塵埃を検知し被掃除面の塵埃量レベルを算出する塵埃検知手段５を備えている。またホース４と延長管７との接続部には、使用者が持つための把手部６を備え、把手部６には、電動送風機２の動作および停止を指示するための操作部６１と、吸込具８の移動速度を検知する速度検知手段６２と、塵埃検知手段５が算出した塵埃量レベルを使用者に知らせるための表示部６３を備えている。 Near the connecting portion between the hose 4 and the main body 1, there is provided dust detection means 5 for detecting the sucked dust and calculating the dust amount level of the surface to be cleaned. The connecting portion between the hose 4 and the extension pipe 7 is provided with a handle portion 6 for the user to hold. The handle portion 6 includes an operation portion 61 for instructing the operation and stop of the electric blower 2, and suction. A speed detector 62 for detecting the moving speed of the tool 8 and a display unit 63 for notifying the user of the dust amount level calculated by the dust detector 5 are provided.
　図２は、同電気掃除機の制御ブロック図である。図２において、塵埃検知手段５は、赤外線発光部５０、赤外線受光部５１、信号増幅部５３、パルス変換部５４、計測部５５で構成されている。赤外線発光部５０より照射された赤外線が、赤外線受光部５１で受光され、この２つの間を塵埃が通過したときの受光量を電気信号に変換する。この変換された電気信号は、受光量によって変化するため、通過した塵埃が大きいほど電気信号の変化は大きくなる。 FIG. 2 is a control block diagram of the electric vacuum cleaner. In FIG. 2, the dust detection means 5 includes an infrared light emitting unit 50, an infrared light receiving unit 51, a signal amplification unit 53, a pulse conversion unit 54, and a measurement unit 55. Infrared light emitted from the infrared light emitting unit 50 is received by the infrared light receiving unit 51, and the amount of light received when dust passes between the two is converted into an electrical signal. Since the converted electrical signal changes depending on the amount of received light, the change in the electrical signal increases as the amount of dust that passes through increases.
　信号増幅部５３は、赤外線受光部５１からの電気信号の変化量を増幅しパルス変換部５４に伝達する。パルス変換部５４は、信号増幅部５３で増幅された赤外線受光部５１からの電気信号の変化量が所定以上であった場合にパルス信号を計測部５５に出力する。計測部５５は、パルス変換部５４から受け取ったパルス信号の数を計測し、０．５秒毎にその間のパルス数から塵埃量のレベルを算出する。 The signal amplifying unit 53 amplifies the change amount of the electric signal from the infrared light receiving unit 51 and transmits it to the pulse converting unit 54. The pulse conversion unit 54 outputs a pulse signal to the measurement unit 55 when the amount of change in the electrical signal from the infrared light receiving unit 51 amplified by the signal amplification unit 53 is greater than or equal to a predetermined value. The measuring unit 55 measures the number of pulse signals received from the pulse converting unit 54, and calculates the level of the dust amount from the number of pulses during every 0.5 seconds.
　図３はその塵埃量レベルの判定を示す図である。０．５秒間のパルス数が９以下だと塵埃量レベル０（ごみ無し）と判断し、パルス数が増える毎に、塵埃量レベル１、２、３（ごみ有り）へと塵埃量レベルが変化する。 FIG. 3 is a diagram showing the determination of the dust amount level. If the number of pulses for 0.5 seconds is 9 or less, it is judged that the dust level is 0 (no dust), and the dust level changes to dust level 1, 2, 3 (with dust) as the number of pulses increases. To do.
　図１および図２に示す表示部６３は、この算出された塵埃量レベルを、図４Ａ～図４Ｄに示すように段階的に表示し、使用者に、塵埃が被掃除面にどれだけ存在するかを知らせる。この表示を見ながら掃除を行うことで、塵埃が無い箇所を掃除して無駄な電力を消費したり、塵埃が多い箇所をあまり掃除しないで塵埃を取り残したりすることがなくなる。その結果、省エネを実現しつつ塵埃の取り残しが無い確実な掃除をすることが可能になる。 The display unit 63 shown in FIGS. 1 and 2 displays the calculated dust amount level in a stepwise manner as shown in FIGS. 4A to 4D, and to the user, how much dust is present on the surface to be cleaned. Let me know. By cleaning while looking at this display, it is possible to avoid unnecessary power consumption by cleaning a place where there is no dust, or leaving the dust without cleaning much where there is a lot of dust. As a result, it is possible to perform reliable cleaning without realizing leaving of dust while realizing energy saving.
　次に、図１および図２に示す速度検知手段６２の動作について説明する。速度検知手段６２は、加速度を検知する加速度検知部６２１と、加速度検知部６２１の加速度検知信号から速度を計算する速度算出部６２２で構成される。使用者は、掃除の際に把手部６を持って前後させると、吸込具８も前後し被掃除面の塵埃を吸引する。速度算出部６２２は、この把手部６の加速度から吸込具８の移動速度を算出する。 Next, the operation of the speed detection means 62 shown in FIGS. 1 and 2 will be described. The speed detection unit 62 includes an acceleration detection unit 621 that detects acceleration and a speed calculation unit 622 that calculates a speed from the acceleration detection signal of the acceleration detection unit 621. When the user holds the handle portion 6 back and forth during cleaning, the suction tool 8 also moves back and forth to suck dust on the surface to be cleaned. The speed calculation unit 622 calculates the moving speed of the suction tool 8 from the acceleration of the handle unit 6.
　なお、速度検知手段６２が出力する速度信号の更新間隔は２．５秒である。これは使用者が吸込具８を操作する際には往復運動を行うことが多く、その往復運動の往復時間よりも十分長くすることで、速度検知の精度を確保できるようにしている。 It should be noted that the update interval of the speed signal output by the speed detection means 62 is 2.5 seconds. In many cases, when the user operates the suction tool 8, the user reciprocates, and the reciprocating time of the reciprocating motion is sufficiently longer to ensure the accuracy of speed detection.
　以上のように構成された本実施の形態における電気掃除機について、以下その動作、作用を説明する。 The operation and action of the vacuum cleaner in the present embodiment configured as described above will be described below.
　先述の通り塵埃検知手段５は、０．５秒毎に吸引した塵埃量によって被掃除面の塵埃量レベルを算出し出力するものであるが、この塵埃量レベルを決定するための０．５秒毎の塵埃吸引量は、被掃除面毎の電気掃除機の塵埃除去性能と、使用者の掃除の仕方によって決定される。このうち、被掃除面毎の電気掃除機の塵埃除去性能については、吸引力や吸込具８の性能、すなわち電気掃除機の製造者側で決定されるものであり、その精度は、確保可能である。しかし、使用者の掃除の仕方については、掃除をする際の動作、すなわち使用者側で決定されるため、その精度は保証できないものである。 As described above, the dust detection means 5 calculates and outputs the dust amount level of the surface to be cleaned based on the amount of dust sucked every 0.5 seconds, and 0.5 seconds for determining this dust amount level. The amount of dust suction for each is determined by the dust removal performance of the vacuum cleaner for each surface to be cleaned and the way the user cleans. Among these, the dust removal performance of the vacuum cleaner for each surface to be cleaned is determined by the suction force and the performance of the suction tool 8, that is, the manufacturer of the vacuum cleaner, and the accuracy can be ensured. is there. However, since the user's cleaning method is determined by the operation at the time of cleaning, that is, the user side, the accuracy cannot be guaranteed.
　この使用者の掃除の仕方の目安として、吸込具８の移動速度をモニターした結果、移動速度の最大値は１．７ｍ／ｓであり、最小値は０．７ｍ／ｓであり、平均値１．１ｍ／ｓ、であった。このように、吸込具８の移動速度には、使用者によって約２．４倍の差があることがわかった。 As a guideline for the user's cleaning method, as a result of monitoring the moving speed of the suction tool 8, the maximum value of the moving speed is 1.7 m / s, the minimum value is 0.7 m / s, and the average value is 1 1 m / s. Thus, it was found that the moving speed of the suction tool 8 has a difference of about 2.4 times depending on the user.
　次に、図５に、所定量の塵埃を撒いた床面に対して、吸込具８の移動速度を変えながら掃除した際の０．５秒あたりの塵埃の吸引量を測定した結果を示す。電気掃除機の塵埃除去性能は、モニター平均である１．１ｍ／ｓに合わせて最大の塵埃除去性能が発揮できるように設計しているため、それより移動速度が速すぎる場合は、塵埃が取れずに０．５秒あたりの塵埃の吸引量が低下し、逆に遅すぎる場合は、塵埃は取れるが掃除面積が狭いため０．５秒あたりの塵埃除去性能が低下することが分かる。 Next, FIG. 5 shows the result of measuring the amount of dust sucked per 0.5 second when cleaning the floor with a predetermined amount of dust while changing the moving speed of the suction tool 8. The vacuum cleaner's dust removal performance is designed to achieve the maximum dust removal performance according to the monitor average of 1.1 m / s, so if the moving speed is too fast, dust can be removed. However, if the suction amount of dust per 0.5 second decreases, and if it is too late, dust can be taken out, but the cleaning area is small, so the dust removal performance per 0.5 second is reduced.
　このように塵埃除去性能が低下した場合、図３に示す判定によって算出する塵埃量レベルが下がり、被掃除面の塵埃について実際よりも少ないと判断してしまい、表示部６３が表示する塵埃量レベルが下がってしまうことで、被掃除面の塵埃量に対して十分な吸引力が得られないため、塵埃の取り残しが生じてしまう恐れがある。 When the dust removal performance is thus reduced, the dust amount level calculated by the determination shown in FIG. 3 is lowered, and it is determined that the dust on the surface to be cleaned is less than the actual amount, and the dust amount level displayed on the display unit 63 is displayed. If the pressure is lowered, a sufficient suction force cannot be obtained with respect to the amount of dust on the surface to be cleaned.
　これに対して本実施の形態では、速度検知手段６２の検知速度に応じて補正部２１が塵埃検知手段５の塵埃検知感度を補正する。感度の補正は、図２に示すように補正部２１が、吸込具８の移動速度に応じた補正係数を計測部５５に出力し、計測部５５はその補正係数を、図３に示す判定の０．５秒間のパルス数の閾値に乗算することで実現する。 In contrast, in the present embodiment, the correction unit 21 corrects the dust detection sensitivity of the dust detection unit 5 according to the detection speed of the speed detection unit 62. For correction of sensitivity, the correction unit 21 outputs a correction coefficient corresponding to the moving speed of the suction tool 8 to the measurement unit 55 as shown in FIG. 2, and the measurement unit 55 displays the correction coefficient in the determination shown in FIG. This is realized by multiplying the threshold value of the number of pulses for 0.5 seconds.
　図６はその補正係数を示す図であり、図７Ａ、図７Ｂは補正後の判定を示す図である。０．５秒あたりの塵埃の吸引量の低下が少ない移動速度が０．６ｍ／ｓ以上、１．５ｍ／ｓ未満の場合を標準的な移動速度範囲として設定し、図３に示す判定の閾値をそのまま用いる。この移動速度範囲外になる場合、すなわち塵埃の吸引量の低下が大きい移動速度が１．５ｍ／ｓ以上の場合や０．６ｍ／ｓ未満の場合は、判定を示す図のパルス数の閾値を下げる。このことで、塵埃量レベルが高めになるように補正することができ、塵埃の吸引量が低下しても、被掃除面の塵埃量に応じた正しい塵埃量レベルの判断ができるようになる。この補正係数は、移動速度に応じたパルス数の変化、被掃除面の塵埃の残存量、使用者の使用実感等により決定されるものである。 FIG. 6 is a diagram showing the correction coefficient, and FIGS. 7A and 7B are diagrams showing the determination after correction. The determination threshold shown in FIG. 3 is set as a standard moving speed range when the moving speed with a small decrease in the suction amount of dust per 0.5 second is 0.6 m / s or more and less than 1.5 m / s. Is used as is. When the moving speed is out of the range, that is, when the moving speed at which the amount of dust suction is greatly reduced is 1.5 m / s or more or less than 0.6 m / s, the threshold value of the number of pulses in the figure indicating the determination is set. Lower. As a result, the dust level can be corrected to be higher, and the correct dust level can be determined according to the amount of dust on the surface to be cleaned even if the amount of sucked dust decreases. This correction coefficient is determined by the change in the number of pulses according to the moving speed, the remaining amount of dust on the surface to be cleaned, the user's feeling of use, and the like.
　すなわち、本実施の形態では補正部２１が移動速度について予め設定した閾値（０．６ｍ／ｓおよび１．５ｍ／ｓ）を持ち、速度検知手段６２の検知する移動速度が閾値を越えた場合に塵埃検知手段５の塵埃量レベルが高くなるように補正されている。 That is, in the present embodiment, the correction unit 21 has thresholds (0.6 m / s and 1.5 m / s) set in advance for the moving speed, and the moving speed detected by the speed detecting means 62 exceeds the threshold. The dust level of the dust detection means 5 is corrected so as to increase.
　なお、図７Ａは図３に示す判定のパルス数に、図６に示す移動速度１．５ｍ／ｓ以上の補正係数０．８５を乗じた判定を示す図であり、図７Ｂは図３に示す判定のパルス数に、図６に示す移動速度０．６ｍ／ｓ以上の補正係数０．８０を乗じた判定を示す図である。 7A is a diagram showing a determination obtained by multiplying the number of determination pulses shown in FIG. 3 by a correction coefficient of 0.85 having a moving speed of 1.5 m / s or more shown in FIG. 6, and FIG. 7B is a diagram showing in FIG. It is a figure which shows the determination which multiplied the correction coefficient 0.80 of the moving speed 0.6m / s or more shown in FIG. 6 to the pulse number of determination.
　以上のような制御を行うことで、使用者の掃除の仕方に応じた適切な感度を設定でき、塵埃の取り残しが無い、より確実な掃除ができる電気掃除機を提供することが可能になる。 By performing the control as described above, it is possible to provide an electric vacuum cleaner that can set an appropriate sensitivity according to the user's cleaning method, and can perform more reliable cleaning without leaving any dust.
　なお、本実施の形態では吸込具８の移動速度について述べたが、塵埃の吸引口は、吸込具８以外にも吸込具８と延長管７との接続部や、延長管７とホース４との接続部に切り替え可能であるため、その箇所の移動速度を検知し、塵埃量レベルを補正することで同様の効果を得ることができる。 In addition, although the moving speed of the suction tool 8 was described in this Embodiment, the suction port of dust is not only the suction tool 8 but also the connection part of the suction tool 8 and the extension pipe 7, and the extension pipe 7 and the hose 4 Therefore, the same effect can be obtained by detecting the moving speed of the part and correcting the dust amount level.
　この場合、吸引口の移動速度と、０．５秒あたりの集塵量は、図５とは異なるため、吸引口の状態に合わせて補正部２１の補正係数を切り替えることで、より確実に塵埃量レベルの補正が可能になる。 In this case, since the moving speed of the suction port and the amount of dust collected per 0.5 second are different from those in FIG. 5, the dust can be more reliably detected by switching the correction coefficient of the correction unit 21 according to the state of the suction port. The quantity level can be corrected.
　また、本実施の形態では、速度検知手段６２を把手部６に設置しているが、これは吸引口が吸込具８である場合、吸込具８と延長管７との接続部である場合、あるいは延長管７とホース４との接続部である場合のどの場合であっても速度検知を可能にするためのもので、これにより、吸引口毎に速度検知手段６２を設ける必要が無く低コスト化が可能になるからである。 Moreover, in this Embodiment, although the speed detection means 62 is installed in the handle part 6, when this is a connection part of the suction tool 8 and the extension pipe 7, when a suction port is the suction tool 8, Alternatively, in any case where the extension pipe 7 and the hose 4 are connected, it is possible to detect the speed, so that it is not necessary to provide the speed detecting means 62 for each suction port and the cost is low. This is because it becomes possible.

FIG. 8 is a graph showing the relationship between the moving speed of the suction tool of the vacuum cleaner and the suction amount of dust per 0.5 second in the second embodiment of the present invention, and FIG. It is a correction coefficient table of a correction means. 10A and 10B are diagrams illustrating determination of the dust amount level of the measurement unit when correction is performed by the correction unit of the electric vacuum cleaner according to the present embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
　本実施の形態における電気掃除機と、実施の形態１における電気掃除機と異なる点は、本実施の形態における電気掃除機では、図８に示すように吸込具８の移動速度が速い方が０．５秒あたりの塵埃の吸引量が多くなることである。これは、吸込具８や電動送風機２の性能が高く、吸込具８の移動速度が速くても塵埃除去性能が十分に確保できる場合に起こる現象である。 The difference between the vacuum cleaner in the present embodiment and the vacuum cleaner in the first embodiment is that, in the vacuum cleaner in the present embodiment, the moving speed of the suction tool 8 is faster as shown in FIG. The amount of dust suction per 5 seconds increases. This is a phenomenon that occurs when the performance of the suction tool 8 and the electric blower 2 is high and the dust removal performance can be sufficiently ensured even when the moving speed of the suction tool 8 is fast.
　この場合は、補正係数を、図９のように移動速度が１．５ｍ／ｓ以上の場合の１．１０にし、図１０Ａのように塵埃量レベルが上がりにくくすることで、塵埃量レベルを不要に高く表示してしまい、使用者が必要以上に掃除して無駄なエネルギーを消費してしまうということを防ぐことができる。 In this case, the correction coefficient is set to 1.10 when the moving speed is 1.5 m / s or more as shown in FIG. 9, and the dust amount level is not easily raised as shown in FIG. It is possible to prevent the user from consuming unnecessary energy by cleaning more than necessary.
　すなわち、本実施の形態の図１０Ａでは、補正部２１が移動速度について予め設定した閾値（１．５ｍ／ｓ）を持ち、速度検知手段６２の検知する移動速度が閾値（１．５ｍ／ｓ）を越えた場合に塵埃検知手段５の塵埃量レベルが低くなるよう補正している。また図１０Ｂでは移動速度について予め設定した閾値（０．６ｍ／ｓ）を持ち、速度検知手段６２の検知する移動速度が閾値（０．６ｍ／ｓ）を小さく越えた場合に、塵埃量レベルが高くなるように補正している。 That is, in FIG. 10A of the present embodiment, the correction unit 21 has a preset threshold value (1.5 m / s) for the moving speed, and the moving speed detected by the speed detecting means 62 is the threshold value (1.5 m / s). When the value exceeds the value, the dust amount level of the dust detection means 5 is corrected to be low. In FIG. 10B, when the moving speed has a preset threshold value (0.6 m / s) and the moving speed detected by the speed detecting means 62 slightly exceeds the threshold value (0.6 m / s), the dust amount level is It is corrected to be higher.
　なお、図１０Ｂは図９に示す判定のパルス数に、図６に示す移動速度０．６ｍ／ｓ以上の補正係数０．８０を乗じた判定を示す図である。 Note that FIG. 10B is a diagram showing a determination obtained by multiplying the number of determination pulses shown in FIG. 9 by a correction coefficient 0.80 of a moving speed of 0.6 m / s or more shown in FIG.
　なお、本実施の形態では吸込具８の移動速度について述べたが、塵埃の吸引口は、吸込具８以外にも吸込具８と延長管７との接続部や、延長管７とホース４との接続部に切り替え可能であるため、その箇所の移動速度を検知し、塵埃量レベルを補正することで同様の効果を得ることができる。 In addition, although the moving speed of the suction tool 8 was described in this Embodiment, the suction port of dust is not only the suction tool 8 but also the connection part of the suction tool 8 and the extension pipe 7, and the extension pipe 7 and the hose 4 Therefore, the same effect can be obtained by detecting the moving speed of the part and correcting the dust amount level.
　この場合、吸引口の移動速度と、０．５秒あたりの集塵量は、図８とは異なるため、吸引口の状態に合わせて補正部２１の補正係数を切り替えることで、より確実に塵埃量レベルの補正が可能になる。 In this case, since the moving speed of the suction port and the amount of dust collected per 0.5 second are different from those in FIG. 8, the dust can be more reliably switched by switching the correction coefficient of the correction unit 21 according to the state of the suction port. The quantity level can be corrected.
　また、本実施の形態では、速度検知手段６２を把手部６に設置しているが、これは吸引口が吸込具８である場合、吸込具８と延長管７との接続部である場合、あるいは延長管７とホース４との接続部である場合のどの場合であっても速度検知を可能にするためのもので、これにより、吸引口毎に速度検知手段を設ける必要が無く低コスト化が可能になるからである。 Moreover, in this Embodiment, although the speed detection means 62 is installed in the handle part 6, when this is a connection part of the suction tool 8 and the extension pipe 7, when a suction port is the suction tool 8, Alternatively, it is for enabling speed detection in any case where the extension pipe 7 and the hose 4 are connected, thereby reducing the cost because it is not necessary to provide speed detecting means for each suction port. This is because it becomes possible.
　（実施の形態３）
　図１１は、本発明の実施の形態３における電気掃除機の制御ブロック図である。なお、上記実施の形態１と同一構成部品については同一符号を付し、説明を省略する。本実施の形態における電気掃除機と、上記実施の形態１における電気掃除機と異なる点は、本実施の形態における電気掃除機では、塵埃検知手段５の感度の補正方法として、信号増幅部５３の信号増幅度を変化させ、検知可能な塵埃の大きさを補正することである。その制御ブロック図を図１１に示す。 (Embodiment 3)
FIG. 11 is a control block diagram of the electric vacuum cleaner according to Embodiment 3 of the present invention. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The difference between the vacuum cleaner in the present embodiment and the vacuum cleaner in the first embodiment is that, in the vacuum cleaner in the present embodiment, as a method for correcting the sensitivity of the dust detection means 5, The signal amplification degree is changed to correct the size of the detectable dust. The control block diagram is shown in FIG.
　以下補正方法の具体的な動作を説明する。０．５秒あたりの塵埃の吸引量の低下が大きい１．５ｍ／ｓ以上や０．６ｍ／ｓ未満の場合、補正部２１は、信号増幅部５３の信号増幅度を上げるよう補正信号を出力する。信号増幅部５３は、その信号を受け、信号の増幅度を上げる。これにより、より小さな塵埃でもパルス変換部５４がパルスを出力するようになるため、０．５秒間のパルス数が増加する。その結果、移動速度要因でのパルス数の減少をカバーすることができ、塵埃量レベルを補正することができる。 The following describes the specific operation of the correction method. When the reduction in the amount of sucked dust per 0.5 second is 1.5 m / s or more and less than 0.6 m / s, the correction unit 21 outputs a correction signal to increase the signal amplification degree of the signal amplification unit 53. To do. The signal amplifying unit 53 receives the signal and increases the amplification degree of the signal. Thereby, since the pulse converter 54 outputs a pulse even with smaller dust, the number of pulses for 0.5 seconds increases. As a result, a decrease in the number of pulses due to the moving speed factor can be covered, and the dust amount level can be corrected.
　なお、検知可能な塵埃の大きさを補正する方法としては、他に赤外線発光部５０の光量を変化させて塵埃通過時の光量の変化を補正したり、パルス変換部５４のパルスを出力する基準とする信号変化量の大きさを補正させたりする方法がある。 In addition, as a method of correcting the size of the dust that can be detected, other standards for changing the light amount of the infrared light emitting unit 50 to correct the change of the light amount when passing through the dust or outputting the pulse of the pulse converting unit 54 are provided. There is a method of correcting the magnitude of the signal change amount.

　また、本発明は、補正部が、移動速度について予め設定した閾値を持ち、速度検知手段の検知する移動速度がこの閾値を越えた場合に塵埃検知手段の塵埃量レベルが低くなるよう補正させるもので、塵埃量レベルが不要に高く表示され、使用者が必要以上に掃除して無駄なエネルギーを消費してしまうということを防ぐことができる。 Further, according to the present invention, the correction unit has a preset threshold for the moving speed, and corrects the dust amount level of the dust detecting means to be low when the moving speed detected by the speed detecting means exceeds the threshold. Therefore, it is possible to prevent the dust amount level from being displayed unnecessarily high and the user from cleaning more than necessary and consuming unnecessary energy.

Since there is no need to provide speed detection means for each suction port, it is possible to provide an electric vacuum cleaner that is low in cost and does not leave any dust depending on how the user cleans.
　さらに、本発明は、速度検知手段として往復運動を検知する往復運動検知部を用い、この往復運動検知部から発信される往復運動にかかる時間に基づいて吸込口の移動速度を検知する構成とすることにより、加速度を検知するための高価な回路を用いることなく、塵埃量レベルの補正を安価に実現することができ、低コストで、使用者の掃除の仕方に応じて塵埃の取り残しが無い電気掃除機を提供することが可能になる。 Furthermore, the present invention uses a reciprocating motion detection unit that detects reciprocating motion as the speed detecting means, and detects the moving speed of the suction port based on the time required for the reciprocating motion transmitted from the reciprocating motion detecting unit.
