Description

本発明は、一般家庭などにおいて掃除に使用される電気掃除機の制御に関するものである。   The present invention relates to control of a vacuum cleaner used for cleaning in a general home.

近年、さまざまな機能をもつ掃除機が提案されており、塵埃が通過する空気経路内に設けた塵埃センサーによって、塵埃量を判断し電動送風機の制御などを行うものも提案されている（例えば、特許文献１、２参照）。
特公平７−２８８４７号公報 特許第３００６１４５号公報 In recent years, vacuum cleaners having various functions have been proposed, and those that judge the amount of dust and control the electric blower by a dust sensor provided in an air path through which dust passes are also proposed (for example, (See Patent Documents 1 and 2).
Japanese Patent Publication No. 7-28847 Japanese Patent No. 3006145

しかしながら、前記従来の電気掃除機の構成では、塵埃の数について検出信号であるパルスの数で、その大きさについてはパルスの幅で判断しているが、この場合に塵埃の大きさをパルス幅で見るための変換部の回路特性を考慮すると、検出できる塵埃の大きさには制限があることが解かってきた。家庭内にある塵埃の大きさは、掃除機で掃除するものだけでも面積的に数千倍以上の差があり、検出回路の特性（主に、信号の増幅率やその周波数特性など）を小さな塵埃に合わせると大きめの塵埃に対し、パルス数としては反応できてもパルス幅での判断は困難であり、その逆にある程度の大きさに特性を合わせると小さい塵埃に対する反応が困難になった。   However, in the configuration of the conventional vacuum cleaner, the number of dust is determined by the number of pulses as a detection signal, and the magnitude is determined by the width of the pulse. In this case, the size of the dust is determined by the pulse width. In view of the circuit characteristics of the conversion unit for viewing in the above, it has been found that there is a limit to the size of dust that can be detected. The size of dust in the home has a difference of more than several thousand times in area even if it is only cleaned with a vacuum cleaner, and the characteristics of the detection circuit (mainly the signal amplification factor and its frequency characteristics) are small. Even if the number of pulses can respond to large dust when matched to dust, it is difficult to judge by the pulse width, and conversely, if characteristics are matched to a certain size, it becomes difficult to react to small dust.

また、吸気の流速とほぼ同速で吸引される検出部より十分に小さい塵埃に対しては、その大きさがパルス信号の幅として判断できるものではなかった。例えば、通過する塵埃の大きさを直径Ｘの球体、受光部の大きさを直径Ｙの円、通過速度を吸気速度とほぼ等しいＺとすると、通過時間は（Ｘ＋Ｙ）／Ｚであるが、ここでＸ＜＜Ｙであるときには通過時間はＹ／Ｚとなり、塵埃の大きさによる通過時間の変化はほぼ無くなってしまうことになる。逆に、ある程度の大きさがあれば、通過時間にＸの数値が影響を与えるとともに、吸気速度に対してその通過速度も遅くなる傾向もでてくるため、開示されている従来技術のようにパルス信号の幅による塵埃の大きさ判断が可能になる。よって、これまではある程度の大きさの塵埃に特性を合わせており、その制御についても十分に小さな塵埃に対しての有効な電力制御や表示制御を行うことができなかった。   Further, the size of the dust that is sufficiently smaller than the detection part sucked at the same speed as the flow velocity of the intake air cannot be determined as the width of the pulse signal. For example, if the size of the passing dust is a sphere with a diameter X, the size of the light receiving part is a circle with a diameter Y, and the passing speed is Z, which is substantially equal to the intake speed, the passing time is (X + Y) / Z. When X << Y, the transit time is Y / Z, and the change in transit time due to the size of dust is almost eliminated. On the contrary, if there is a certain size, the numerical value of X will affect the passage time, and the passage speed tends to be slower than the intake speed. The size of the dust can be determined based on the width of the pulse signal. Thus, until now, characteristics have been matched to a certain size of dust, and effective power control and display control for sufficiently small dust could not be performed.

本発明は、これら従来の課題を解決するもので、さまざまな塵埃の大きさに対して特性を合わせた複数の検出信号を出力できる検出部を備えた上で、複数の検出信号に対する判断をすることで、より精度よく小さい塵埃に対する制御を行える使用性を向上した電気掃除機を提供することを目的とする。   In order to solve these conventional problems, the present invention includes a detection unit capable of outputting a plurality of detection signals having characteristics matched to various dust sizes, and makes a determination on the plurality of detection signals. Thus, an object of the present invention is to provide a vacuum cleaner with improved usability capable of controlling small dust with higher accuracy.

これにより、塵埃の大きさについて小さな塵埃に適した検出信号とより大きな塵埃に適した検出信号とで判断して、より精度よく電動送風機の制御を行うことができる。   As a result, the size of the dust can be determined based on the detection signal suitable for small dust and the detection signal suitable for larger dust, and the electric blower can be controlled with higher accuracy.

By this input, the judgment control means 9 Clears the accumulated amount and starts determining the next accumulated amount.

以下、その動作を説明する。   Hereinafter, the operation will be described.

まず、本体１を商用電源（図示せず）に接続し、使用者は操作部４によって運転を指示する。操作部４から判断制御手段９に操作信号が送られ、操作された内容にしたがって、判断制御手段９は初期値（例えば３００Ｗ）の電力で運転が行われるように駆動手段８へ駆動信号を送る。駆動手段８は送られてきた信号によって電動送風機２への通電を行い、電動送風機２は回転を開始し、吸引力が発生する。   First, the main body 1 is connected to a commercial power source (not shown), and the user instructs operation by the operation unit 4. An operation signal is sent from the operation unit 4 to the judgment control means 9, and the judgment control means 9 sends a drive signal to the drive means 8 so that the operation is performed with an initial value (for example, 300 W) according to the operated content. . The drive means 8 energizes the electric blower 2 according to the sent signal, and the electric blower 2 starts to rotate and a suction force is generated.

この吸引力によって、吸引された塵埃は、ホース３を経て本体１内の集塵室６の集塵袋５へ集塵される。この間、集塵検出部７の吸引経路内を塵埃が通過する、つまり発光部と受光部の間を塵埃が通過することで受光量が変化するので、塵埃検出手段１０は、検出信号として分別信号出力手段１１に送る。分別信号出力手段１１では受けた信号をまず、第１増幅部で増幅し、この結果が、所定の閾値を越えていれば、第１の塵埃検出信号として出力する。さらに、第１の塵埃検出信号として出力するレベルであるかないかに関わらず、第２増幅部での増幅結果が、所定の閾値を越えていれば、第２の塵埃検出信号として出力する。つまり、比較的大きな塵埃の場合には、第１増幅率でも反応したと判定できるので、第１の塵埃検出信号、第２の塵埃検出信号ともに出力される。小さな塵埃の場合には第１増幅率では判定レベルに達せず、第２増幅率でのみ反応したと判定できるので、第２の塵埃検出信号のみが検出される。増幅率の差で判定を分別することで、受発光部分の通過速度が等しく、パルス幅では十分な差が得られない塵埃（例えば径が０．１ｍｍの塵埃と０．０３ｍｍの塵埃）であっても、信号として区別できる。   Due to this suction force, the sucked dust is collected through the hose 3 into the dust collection bag 5 of the dust collection chamber 6 in the main body 1. During this time, the amount of received light changes when the dust passes through the suction path of the dust collection detection unit 7, that is, when the dust passes between the light emitting unit and the light receiving unit. Send to output means 11. The classification signal output means 11 first amplifies the received signal by the first amplifying unit, and if the result exceeds a predetermined threshold value, outputs it as a first dust detection signal. Furthermore, regardless of whether the output level is the first dust detection signal or not, if the amplification result in the second amplification unit exceeds a predetermined threshold value, the second dust detection signal is output. That is, in the case of relatively large dust, since it can be determined that the first amplification factor has reacted, both the first dust detection signal and the second dust detection signal are output. In the case of small dust, the first amplification factor does not reach the determination level, and since it can be determined that the reaction has occurred only at the second amplification factor, only the second dust detection signal is detected. By classifying the judgment based on the difference in amplification factor, the passage speeds of the light emitting and receiving parts are equal, and the difference in pulse width cannot be obtained sufficiently (for example, dust having a diameter of 0.1 mm and dust having a diameter of 0.03 mm). However, it can be distinguished as a signal.

次に、第１塵埃計数手段１２は第１の塵埃検出信号をあらかじめ定めた所定単位時間カウントし、そのカウント結果を判断制御手段９へ送り、第２塵埃計数手段１３は第２の塵埃検出信号を同様に所定単位時間カウントし、そのカウント結果を判断制御手段９へ送る。判断制御手段９は、図２に示すように、第１の塵埃計数手段１２の計数結果と第２の塵埃計数手段１３の計数結果との値を、例えば３倍比で総塵埃量として積算し、被掃除面の汚れ具合の判定を行い、例えば下記に示す表１のように、その度合いに応じた電動送風機２の電力供給量を決定して、駆動手段８への信号を送る。駆動手段８はその信号に従って電動送風機２を駆動し、塵埃量に応じた電動送風機２の運転が可能となる。このとき、総塵埃量の算出については第１増幅率と第２増幅率の比をもとに適量となるよう設定することで、従来では困難であった大きさの塵埃も検出でき、検出可能な塵埃の大きさの領域が広がった上で塵埃量に応じたパワーで運転できる。   Next, the first dust counting means 12 counts the first dust detection signal for a predetermined unit time, sends the count result to the judgment control means 9, and the second dust counting means 13 sends the second dust detection signal. Is counted for a predetermined unit time, and the count result is sent to the judgment control means 9. As shown in FIG. 2, the judgment control means 9 integrates the value of the count result of the first dust count means 12 and the count result of the second dust count means 13 as a total dust amount at a triple ratio, for example. Then, the degree of contamination of the surface to be cleaned is determined, for example, as shown in Table 1 below, the power supply amount of the electric blower 2 corresponding to the degree is determined, and a signal to the driving means 8 is sent. The drive means 8 drives the electric blower 2 according to the signal, and the electric blower 2 can be operated according to the amount of dust. At this time, the calculation of the total amount of dust can be detected by detecting the size of dust that was difficult in the past by setting the appropriate amount based on the ratio between the first amplification factor and the second amplification factor. It is possible to operate with a power corresponding to the amount of dust after an area of a large size of dust is expanded.

もちろん初期値については、使用者が操作する操作部４の設定で異なるようにできるようにそれに適した汚れ度による電力設定すなわち電力上昇設定を持たせるようにするだけでなく、電力の上昇レベルを使用者に選択させるようにして、使用者の使い勝手をよくするようにしてもよい。   Of course, the initial value is set not only to have a power setting based on the degree of contamination suitable for the setting of the operation unit 4 operated by the user, that is, a power increase setting, but also to increase the power increase level. The user may be allowed to make a selection so as to improve the usability of the user.

Figure 0004654794

また、図３に示すように、第１の塵埃計数手段１２と第２の塵埃計数手段１３の結果を積算するのではなく、個別に判断し、制御する手段もある。例えば、表２に示すようにそれぞれのカウントされた塵埃量に対し、電力設定を持たせる。第２の塵埃計数手段１３によってカウントされる塵埃は、第１の塵埃計数手段１２によってカウントされる塵埃より小さく、その数は多くなる。このことから、汚れ度判定の絶対値は大きくし、同時に必要な吸引力は少なくてよい。これを考慮して、下記に示す表２のような個別に適応させた設定ができる。もちろん、複数の制御則を準備して、操作部４により選択させることで使用者が使いたい運転を選択させてもよい。このとき、第１の塵埃計数手段１２でカウントできる塵埃は、第２の塵埃計数手段１３でも同時にカウントされるので、通常はこれを考慮したうえで設定するが、回路構成によって第１の塵埃検出信号と第２の塵埃検出信号の出力が排他的な処理を行ってどちらかしか出力されないようにし、通信回路の効率化を図ることでコストを抑える方法もあるので、その場合には、判断制御手段９において自動的に第１の塵埃計数結果を第２の塵埃計数結果に加算する選択機能を持たせることで、回路構成に左右されることなく制御を合わせることができる。   Further, as shown in FIG. 3, there is a means for individually determining and controlling the results of the first dust counting means 12 and the second dust counting means 13 instead of integrating the results. For example, as shown in Table 2, a power setting is given to each counted amount of dust. The dust counted by the second dust counting means 13 is smaller than the dust counted by the first dust counting means 12, and the number thereof is increased. For this reason, the absolute value of the degree of contamination determination is increased, and at the same time, the required suction force may be reduced. Taking this into consideration, settings individually adapted as shown in Table 2 below can be made. Of course, it is also possible to prepare a plurality of control laws and select the operation that the user wants to use by selecting them with the operation unit 4. At this time, the dust that can be counted by the first dust counting means 12 is also counted by the second dust counting means 13 at the same time, and is usually set in consideration of this, but the first dust detection is performed depending on the circuit configuration. There is also a method of suppressing the cost by making the output of the signal and the second dust detection signal exclusive to perform only one of them and improving the efficiency of the communication circuit. By providing the selection function of automatically adding the first dust count result to the second dust count result in the means 9, the control can be adjusted without depending on the circuit configuration.

第１の塵埃計数手段１２及び第２の塵埃計数手段１３の結果にもとづく電力設定から判断制御手段９は電動送風機２の電力供給量を決定して、駆動手段８への信号を送る。駆動手段８はその信号に従って電動送風機２を駆動し、塵埃量に応じた電動送風機２の運転が可能となる。第１塵埃計数手段１２の出力による第１汚れ度と、第２塵埃計数手段１３の出力による第２汚れ度の判定に対して、個々の汚れ具合に適応させた電力設定値を、強いものに合わせることで、必要なパワーを設定するようにすれば、よりきめ細かい汚れ度に対する必要なパワー設定が可能なので、エネルギー効率もよい使用性の高い制御が可能になる。   From the power setting based on the results of the first dust counting means 12 and the second dust counting means 13, the judgment control means 9 determines the power supply amount of the electric blower 2 and sends a signal to the driving means 8. The drive means 8 drives the electric blower 2 according to the signal, and the electric blower 2 can be operated according to the amount of dust. The power setting value adapted to the individual dirt condition is made stronger with respect to the determination of the first dirt degree by the output of the first dust counting means 12 and the second dirt degree by the output of the second dust counting means 13. In combination, if the required power is set, the required power can be set for a finer degree of dirt, so that it is possible to perform control with high energy efficiency and high usability.

また、これらの汚れ度に応じて、検出表示手段１４を用いて表示することで、使用者に検出状況を報知すれば、汚れ度すなわち清掃状況に応じた掃除ができるので、効率的な清掃が可能となる。また、小さい塵埃とより大きな塵埃とを区別して表示すればさらに塵埃の分布などもわかり、汚れのたまり具合なども予想できるため、さらに効率的な運転ができる。もちろん、表示ではなく、音声などによる報知でも同様の効果がある。   Moreover, if the detection status is displayed to the user according to the degree of contamination using the detection display means 14, cleaning can be performed according to the degree of contamination, that is, the cleaning status. It becomes possible. Further, if the small dust and the larger dust are displayed separately, the distribution of dust and the like can be understood, and the accumulation of dirt can be predicted, so that more efficient operation can be performed. Of course, the same effect can be obtained by notifying the display but using voice or the like.

また、判断制御手段９は、第１の塵埃計数手段１２及び第２の塵埃計数手段１３の結果から集塵袋５へ集塵された蓄積量が大きさを考慮して判断できるので従来のものより精度よく、その蓄積量を集塵量表示手段１５によって使用者へ報知できる。このとき集塵袋５を交換するなどした場合には、その蓄積量のクリア処理を行うよう蓄積クリア入力手段１６から行えるようにする。集塵袋５の交換を集塵室６内にスイッチやセンサなどを設けて自動的に処理するようにしてもよいのは言うまでもない。   Further, the judgment control means 9 can judge the accumulated amount collected in the dust bag 5 from the results of the first dust counting means 12 and the second dust counting means 13 in consideration of the size. The accumulated amount can be notified to the user by the dust collection amount display means 15 with higher accuracy. At this time, when the dust bag 5 is exchanged, the accumulation clear input means 16 can perform the accumulation amount clear process. Needless to say, the exchange of the dust bag 5 may be automatically processed by providing a switch, a sensor, or the like in the dust chamber 6.

また、本発明では分別信号出力を２種類で行ったが、周波数特性などを考慮して、より多数の信号にわけて制御してもよい。   In the present invention, the classification signal output is performed in two types. However, in consideration of the frequency characteristics and the like, the control may be performed by dividing into more signals.

以上のように、塵埃の大きさに対して特性を合わせた複数の検出信号を判断することで、より精度よく電力制御を行え、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, by determining a plurality of detection signals having characteristics matched to the size of dust, it is possible to perform power control with higher accuracy and to provide a highly usable vacuum cleaner.

以上のように、本発明にかかる電気掃除機は、塵埃検出について小さな塵埃に適した検出信号とより大きな塵埃に適した検出信号とを分別判断し制御することで、より精度よく電力制御を行え、塵埃検出制御を行う電気掃除機に特に有用である。   As described above, the vacuum cleaner according to the present invention can perform power control more accurately by separately determining and controlling a detection signal suitable for small dust and a detection signal suitable for larger dust. It is particularly useful for a vacuum cleaner that performs dust detection control.
