Description

本発明は、電気掃除機に関するもので、特に集塵室内の粗塵フィルターおよび細塵フィルターの除塵動作の制御に関するものである。   The present invention relates to a vacuum cleaner, and more particularly to control of dust removal operation of a coarse dust filter and a fine dust filter in a dust collection chamber.

従来この種の電気掃除機として、集塵した塵埃の処理を容易にするために、電動送風機からの吸い込み経路を切り替え、集塵された塵埃を圧縮して小型化し、集塵量を向上させるものがある。(例えば、特許文献1参照)。   Conventionally, this type of vacuum cleaner switches the suction path from the electric blower in order to facilitate the processing of the collected dust, compresses the collected dust and downsizes it, and improves the amount of collected dust There is. (For example, refer to Patent Document 1).

また、細塵フィルターの除塵はコイルとコアで形成された電磁石の磁界により振動する振動子の振動面を、細塵フィルターに振動伝達可能な場所に接する構成にして、所定時間、コイルを断続的に通電することで、その期間、電磁石が振動子の吸引、乖離を繰り返して振動子に振動を与え、振動面が細塵フィルターの外面を叩くことで、付着した塵埃を除塵している(例えば、特許文献2参照)。

In addition, the dust removal of the fine dust filter is configured so that the vibrating surface of the vibrator that is vibrated by the magnetic field of the electromagnet formed by the coil and the core is in contact with a place where vibration can be transmitted to the fine dust filter, and the coil is intermittently provided for a predetermined time. In that period, the electromagnet repeatedly attracts and separates the vibrator to vibrate the vibrator, and the vibrating surface strikes the outer surface of the fine dust filter to remove the attached dust (for example, , See Patent Document 2).
JP 2003-339598 A Japanese Patent Application Laid-Open No. 5-91962

しかしながら、前記従来の構成においては、吸気通路を切り替えて電動送風機からの負圧で圧縮する構成であるために、圧縮する際には電動送風機の吸込み力を上げ、負圧を大きくしないと圧縮効果が小さく、また粗塵フィルターに付着したごみも取り除けないため、圧縮および除塵を行うには大きな消費電力を必要としており、電動送風機の寿命が低下するという不都合を有していた。   However, in the conventional configuration, since the intake passage is switched and compressed by the negative pressure from the electric blower, the compression effect is increased unless the suction pressure of the electric blower is increased and the negative pressure is increased. In addition, since dust attached to the coarse dust filter cannot be removed, large power consumption is required for compression and dust removal, and the life of the electric blower is reduced.

また綿ゴミのような風量変化の小さい塵埃ではおおきな負圧がかからないため、圧縮効果が小さいという課題も有していた。さらに集塵量に関係なく、一律的な圧縮動作を行うために、塵埃の圧縮を完了していない状態や、粗塵フィルターに付着したごみを除塵していない状態でも終了したり、また逆に圧縮動作や除塵動作が完了した後でも、圧縮動作を継続したりするといった無駄な動作を行って電力を余分に消費するという課題を有していた。   In addition, dust having a small change in air volume, such as cotton dust, does not apply a large negative pressure, and thus has a problem that the compression effect is small. In addition, in order to perform a uniform compression operation regardless of the amount of dust collected, it can be completed even when dust compression has not been completed or dust attached to the coarse dust filter has not been removed. Even after the compression operation and the dust removal operation are completed, there has been a problem that extra power is consumed by performing a useless operation such as continuing the compression operation.

また、細塵フィルターの除塵においても掃除終了後の集塵量に関係なく、一律に除塵動作を行うため、塵埃が確実に全て除去できない状態で除塵動作を終了したり、また逆に集塵手段の除塵が完了した後でも除塵動作を継続したりする、といった無駄な動作を行うという課題を有していた。   Also, dust removal by the fine dust filter is performed uniformly regardless of the amount of dust collected after cleaning, so the dust removal operation can be completed when all dust cannot be removed reliably, or conversely. There is a problem of performing a useless operation such as continuing the dust removal operation even after the dust removal is completed.

本発明は、前記従来の課題を解決するもので、集塵容器内に捕集した集塵量に適合した圧縮動作および除塵動作を行って、電動送風機の停止後に行う圧縮動作および除塵動作の動作時間を短縮し、次の掃除動作を可能にする再開時間を短縮できる電気掃除機を提供することを目的とする。   The present invention solves the above-described conventional problems, and performs a compression operation and a dust removal operation suitable for the amount of dust collected in the dust collection container, and a compression operation and a dust removal operation performed after the electric blower is stopped. An object of the present invention is to provide an electric vacuum cleaner that can shorten the restarting time that shortens the time and enables the next cleaning operation.

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、吸引力を発生させる電動送風機と、吸引された粗塵を捕集する粗塵フィルターおよび細塵を捕集する細塵フィルターを有した集塵容器と、圧縮板と前記圧縮板を駆動する圧縮モータを有し前記粗塵フィルター内に堆積された塵埃を押圧して圧縮動作する圧縮手段と、前記圧縮手段で前記塵埃を圧縮しているときに前記圧縮モータに加わる負荷量を検知する負荷量検知手段と、前記細塵フィルターに付着した細塵を除去する除塵動作を行う除塵手段と、前記粗塵フィルター内の集塵量を検出する集塵量検知手段と、前記負荷量検知手段と前記集塵量検知手段からの信号を受け、前記圧縮手段および前記除塵手段を動作させる制御手段と、を備え、前記圧縮板は、前記負荷量検知手段が所定の負荷量を検知すると後退し、圧縮開始の上死点から元の上死点に戻るまでの間を移動し、前記集塵量検知手段は、前記圧縮板が前記集塵容器
内で移動する移動距離を検出することで構成され、前記制御手段により、前記集塵量検知手段からの集塵量を表す検出信号に応じて前記電動送風機の停止後に動作する前記圧縮手段および前記除塵手段の動作時間を可変させるようにしたものである。
In order to solve the conventional problems, an electric vacuum cleaner according to the present invention includes an electric blower that generates suction force, a coarse dust filter that collects sucked coarse dust, and a fine dust filter that collects fine dust. A dust collecting container, a compression plate and a compression motor that drives the compression plate and compressing the dust by pressing the dust accumulated in the coarse dust filter; and compressing the dust by the compression device A load amount detecting means for detecting a load applied to the compression motor during operation, a dust removing means for performing a dust removing operation for removing fine dust adhering to the fine dust filter, and a dust collection amount in the coarse dust filter And a control means for operating the compression means and the dust removal means in response to signals from the load amount detection means and the dust collection amount detection means, and the compression plate comprises: The load amount detecting means Retract and detects the constant loadings, moves between the top dead center of the start compressed to return to the original top dead point, the dust amount detecting means, said compression plate the dust container
Is constructed by detecting the moving distance traveled by the inner, by the control means, in response to the detection signal representing the dust collection amount from the dust collection amount detection means, the compression means operates after stopping of the electric blower and the operation time of the dust removing means is obtained so as to variably.

この構成によって、粗塵フィルター内に堆積された塵埃を押圧して圧縮し、細塵フィルターに付着した塵埃を掻き落として吸引風の流路を確保することで、電動送風機の消費電力を抑えることができる。また、集塵捕集手段の集塵量に応じて除塵手段や圧縮手段の動作時間を可変し、集塵容器の集塵量が多く、圧縮動作および除塵動作の必要度が高いときには長い時間をかけて確実に圧縮動作および除塵動作を行う。逆に、集塵量が少なく、圧縮動作および除塵動作の必要度が比較的低いときには、圧縮動作および除塵動作の動作時間を短縮することで、圧縮動作および除塵動作から掃除動作への移行を短縮することができる。   With this configuration, the dust accumulated in the coarse dust filter is pressed and compressed, and dust attached to the fine dust filter is scraped off to secure the suction air flow path, thereby reducing the power consumption of the electric blower. Can do. Also, the operation time of the dust removal means and the compression means can be varied according to the amount of dust collected by the dust collection means, and when the amount of dust collection in the dust collection container is large and the necessity of compression and dust removal is high, a long time is required. To perform compression and dust removal. Conversely, when the amount of dust collection is small and the need for compression and dust removal operations is relatively low, shortening the operation time for compression and dust removal operations shortens the transition from compression and dust removal operations to cleaning operations. can do.

本発明の電気掃除機は、圧縮手段の圧縮動作と、除塵手段の除塵動作とによって強い吸引力を維持することができるだけでなく、集塵容器の集塵量が多く、圧縮および除塵の必要度が高いときには、長い時間をかけて確実に圧縮動作および除塵動作を行う。そして、塵埃量が少なく比較的必要度が低いときには、圧縮動作及び除塵手段の動作時間を短縮することで、次の掃除動作へと即座に移行することができる。   The vacuum cleaner of the present invention not only can maintain a strong suction force by the compression operation of the compression means and the dust removal operation of the dust removal means, but also has a large amount of dust collection in the dust collection container, and the necessity of compression and dust removal When is high, the compression operation and the dust removal operation are surely performed over a long time. When the amount of dust is small and the necessity is relatively low, the operation time of the compression operation and the dust removal means can be shortened to immediately move to the next cleaning operation.

逆に、集塵量が少なく、圧縮動作および除塵動作の必要度が比較的低いときには、圧縮動作及び除塵動作の動作時間を短縮することで、次の掃除動作を即座に再開することができると共に、除塵機構の信頼性および寿命を向上することができる。

圧縮手段55は、ギヤ38及び、そのギヤ38を回駆動する圧縮モータ56などから構成され、制御手段52からの信号を受けて圧縮モータ56を回転駆動し、圧縮板30を往復動している。   The compression means 55 includes a gear 38 and a compression motor 56 that drives the gear 38 to rotate. The compression means 55 receives a signal from the control means 52 and rotationally drives the compression motor 56 to reciprocate the compression plate 30. .

除塵手段57は、ギヤ49を回転駆動する除塵モータ58などから構成され、制御手段52からの信号を受けて、除塵手段を駆動している。   The dust removing means 57 is composed of a dust removing motor 58 that rotationally drives the gear 49, and receives a signal from the control means 52 to drive the dust removing means.

集塵量検知手段59は圧縮板30が集塵容器4内で移動する移動距離を検出する圧縮移動量検知手段で構成され、圧縮板30の移動距離によって集塵量を検知するものであり、本実施の形態では、ギヤ38の軸に取り付けられたマグネット(図示せず)の磁力をホールIC(図示せず)などで構成された検出回路(図示せず)で検知することで、その軸の回転数に同期した信号から移動距離を検出している。   The dust collection amount detection means 59 is constituted by a compression movement amount detection means for detecting the movement distance by which the compression plate 30 moves in the dust collection container 4, and detects the dust collection amount by the movement distance of the compression plate 30. In this embodiment, the magnetic force of a magnet (not shown) attached to the shaft of the gear 38 is detected by a detection circuit (not shown) constituted by a Hall IC (not shown) or the like, whereby the shaft The moving distance is detected from a signal synchronized with the number of rotations.

風量検出手段60は、電動送風機2で発生する吸引風の風量を検出するものである。電

The air volume detecting means 60 detects the air volume of the suction air generated by the electric blower 2. There is a certain correlation between the amount of suction air generated by the electric blower 2 and the current value flowing through the electric blower 2, and the current flowing through the electric blower 2 is detected, and the amount of air flow is determined according to the magnitude of the current. It detects the level indirectly.

集塵量報知手段61は、制御手段52の判断した集塵量に基づき、使用者に集塵量を報知する手段であり、本実施の形態ではLEDなどの表示回路で構成している。   The dust collection amount notifying means 61 is means for notifying the user of the dust collection amount based on the dust collection amount judged by the control means 52, and is configured by a display circuit such as an LED in this embodiment.

集塵容器検出手段62は、図5及び図7に示すように、集塵容器4が集塵容器収納部5にセットされているかを検出するものであり、隔壁40に設けられたマイクロスイッチによって構成され、集塵容器収納部5内に集塵容器4を入れたり出したりすることによって、マイクロスイッチがON−OFFするようになっている。   As shown in FIGS. 5 and 7, the dust collection container detecting means 62 detects whether the dust collection container 4 is set in the dust collection container storage portion 5, and is configured by a micro switch provided in the partition wall 40. The microswitch is configured to be turned on and off by putting the dust container 4 in and out of the dust container container 5.

満杯報知手段63は、特に集塵量が所定量以上に溜まっている場合に使用者に捨ててもらうことを促すためのものであり、例えばブザーなどで構成される。   The full notification means 63 is for urging the user to throw away the dust when the amount of collected dust is more than a predetermined amount, and is constituted by a buzzer, for example.

タイマー手段64は、掃除作業の累積時間を検出する手段であり、手元操作手段8の操作によって電動送風機2の動作開始時から動作停止時までの時間を、所定のクロック信号を計数して検出するものである。   The timer means 64 is a means for detecting the cumulative time of the cleaning work, and detects the time from the start of operation of the electric blower 2 to the stop of the operation by operating the hand operation means 8 by counting a predetermined clock signal. Is.

上記のように構成された本実施の形態における電気掃除機の動作、作用について、主に、図7を用いて説明する。   The operation and action of the electric vacuum cleaner configured as described above will be mainly described with reference to FIG.

電気掃除機の使用開始にあたり、使用者が、掃除機本体1の電源プラグ(図示せず)を室内の壁に設けたコンセント(図示せず)に差し込むと、通電検知手段51が掃除機本体1に通電されたことを検知し、検知した信号を制御手段52に送る。制御手段52は、集塵容器検出手段62で集塵容器収納部5内に集塵容器4が在ることを確認すると、圧縮手段55に信号を送って、ギヤ38を回転駆動する圧縮モータ56を駆動する。そして、ギヤ38が回転することによって、圧縮モータ56の回転動力が、駆動軸33に取り付けられたギヤ37を介してラックギヤ31aに伝達され、ラックギヤ31aの動きに連動して圧縮板30が下降し、塵埃を圧縮する。   When the user starts using the electric vacuum cleaner, when the user inserts the power plug (not shown) of the vacuum cleaner main body 1 into an outlet (not shown) provided on the wall of the room, the energization detecting means 51 is connected to the vacuum cleaner main body 1. Is detected, and the detected signal is sent to the control means 52. When the dust collecting container detecting means 62 confirms that the dust collecting container 4 is present in the dust collecting container storage portion 5, the control means 52 sends a signal to the compressing means 55 to rotate the gear 38 for rotation. Drive. As the gear 38 rotates, the rotational power of the compression motor 56 is transmitted to the rack gear 31a via the gear 37 attached to the drive shaft 33, and the compression plate 30 descends in conjunction with the movement of the rack gear 31a. Compress the dust.

そして、圧縮板30が、粗塵室18内に堆積された塵埃を圧縮しながら下降していくと、次第に、圧縮モータ56に加わる負担が増加し、それに伴って圧縮モータ56に流れる電流が次第に増加し、負荷量検出手段53が検出する負荷量(電流値)が所定の負荷量(電流値)を超えると、制御手段52は、粗塵室18内の塵埃が十分圧縮されたと判断する。すると、制御手段52は圧縮モータ56を逆回転させる制御を行って、圧縮板30を最初の上死点まで後退させて、圧縮モータ56の回転駆動を停止する。この一連の動作は、あらかじめ設定した回数内で行われる。   Then, as the compression plate 30 descends while compressing the dust accumulated in the coarse dust chamber 18, the load applied to the compression motor 56 gradually increases, and the current flowing through the compression motor 56 gradually increases accordingly. When the load amount (current value) detected by the load amount detection means 53 exceeds a predetermined load amount (current value), the control means 52 determines that the dust in the coarse dust chamber 18 is sufficiently compressed. Then, the control means 52 performs control to reversely rotate the compression motor 56, retracts the compression plate 30 to the first top dead center, and stops the rotation drive of the compression motor 56. This series of operations is performed within a preset number of times.

このとき、圧縮動作を終了して逆転を開始してから上死点で停止するまでの圧縮板30の移動距離は、集塵容器内に溜まった集塵量が増加するほど減少する関係を持っており、集塵量との間に一定の相関関係にあると考えることができる。ホールIC(図示せず)は、ギヤ38の回転に連動したマグネットの動きを検知して、ギヤ38の回転に応じた数のパルス信号を発生する。そして、集塵量検知手段59は、そのホールICから得られるパルス数から圧縮板30の移動距離を検知し、制御手段52は、集塵量検知手段59で検知した移動距離の情報から集塵容器4内のゴミ量を判断することできる。   At this time, the movement distance of the compression plate 30 from the end of the compression operation to the start of reverse rotation to the stop at the top dead center has a relationship that decreases as the amount of dust collected in the dust collection container increases. Therefore, it can be considered that there is a certain correlation with the amount of collected dust. A Hall IC (not shown) detects the movement of the magnet in conjunction with the rotation of the gear 38 and generates a number of pulse signals corresponding to the rotation of the gear 38. The dust collection amount detection means 59 detects the movement distance of the compression plate 30 from the number of pulses obtained from the Hall IC, and the control means 52 detects the dust collection amount from the movement distance information detected by the dust collection amount detection means 59. The amount of dust in the container 4 can be determined.

その集塵量が所定量を越えていた場合には、制御手段52は満杯報知手段63を起動させ、例えば、ブザーなどによる満杯報知手段63によって、使用者に注意喚起すると共に、電動送風機2の運転を停止することによって、床用吸込具11の吸引力が低い状態で掃
除を継続することを避け、塵埃が集塵容器4から溢れることを防止し、電動送風機2の負担を減らすこともできる。なお、電動送風機2の運転を完全に停止せずに、電動送風機2へ供給する供給電力を制限しても構わない。また、この満杯報知については、圧縮動作直後に報知するだけでなく、次の運転指示を行ったときにも再度報知するようにすれば、より確実に使用者に満杯状態であることを報知することができ、電動送風機2への負担を減らすことができる。また、床用吸込具11の電動機も運転しないようにすれば、塵埃が集塵容器4から溢れたり、吸引できずに床用吸込具11、延長管10、ホース6内に溜まったりことを防ぐことができる。
When the dust collection amount exceeds the predetermined amount, the control means 52 activates the full notification means 63, for example, alerts the user by the full notification means 63 such as a buzzer and the like. By stopping the operation, it is possible to avoid continuing the cleaning with the suction force of the floor suction tool 11 being low, to prevent the dust from overflowing from the dust collecting container 4, and to reduce the burden on the electric blower 2. . Note that the power supplied to the electric blower 2 may be limited without completely stopping the operation of the electric blower 2. In addition, the full notification is notified not only immediately after the compression operation but also when the next operation instruction is given, so that the user is more surely notified that the vehicle is full. And the burden on the electric blower 2 can be reduced. Further, if the electric motor of the floor suction tool 11 is not operated, dust can be prevented from overflowing from the dust collecting container 4 or being collected in the floor suction tool 11, the extension pipe 10, and the hose 6 without being sucked. be able to.

さらに制御手段52は、図5及び図7に示すように、除塵手段57に信号を送って、ギヤ49を回転駆動する除塵モータ58を駆動する。そして、図6に示すように、ギヤ49と噛合ったギヤ34が回転することによって、連結棒45を介して連結された弾き体44が左右に往復移動し、細塵フィルター43の裏面に付着した細塵がふるい落とされる。この上記動作は電源投入から5秒以内の動作時間で終了するようになっている。   Further, as shown in FIGS. 5 and 7, the control means 52 sends a signal to the dust removal means 57 to drive the dust removal motor 58 that rotationally drives the gear 49. Then, as shown in FIG. 6, when the gear 34 engaged with the gear 49 rotates, the flip body 44 connected via the connecting rod 45 reciprocates left and right and adheres to the back surface of the fine dust filter 43. Dust is removed. This operation is finished in an operation time within 5 seconds after the power is turned on.

次に、手元操作手段8を操作して、電気掃除機2の運転を開始すると、制御手段52は駆動手段54に信号を送り、電動送風機2を運転させる。この電動送風機2による吸引力が、細塵フィルター43、粗塵フィルター28及び29、粗塵室18、ホース6、延長管10を経て床用吸込具11に至る。そして、床用吸込具11は床面の塵埃を捕集し、吸引された塵埃を含んだ空気は、掃除機本体1の吸気口7を通って集塵容器本体15の吸入口17から真っ直ぐ粗塵室18に入り、粗塵フィルター28及び29に当たり、塵埃は粗塵フィルター28及び29で捕集され、堆積していく。粗塵フィルター28および29を通過した空気に含まれる細塵は、細塵フィルター43で捕捉される。   Next, when the operation of the vacuum cleaner 2 is started by operating the hand operating means 8, the control means 52 sends a signal to the drive means 54 to operate the electric blower 2. The suction force by the electric blower 2 reaches the floor suction tool 11 through the fine dust filter 43, the coarse dust filters 28 and 29, the coarse dust chamber 18, the hose 6, and the extension pipe 10. The floor suction tool 11 collects dust on the floor surface, and the air containing the sucked dust passes through the air inlet 7 of the cleaner body 1 and is straightened from the air inlet 17 of the dust container main body 15. The dust enters the dust chamber 18 and hits the coarse dust filters 28 and 29. The dust is collected by the coarse dust filters 28 and 29 and accumulated. Fine dust contained in the air that has passed through the coarse dust filters 28 and 29 is captured by the fine dust filter 43.

そして、掃除が終了し、使用者が手元操作手段8によって電動送風機2の停止操作を行うと、制御手段52は、除塵手段57に信号を送って、ギヤを回転駆動する除塵モータ58を駆動する。さらに、停止操作後の所定時間経過後には、制御手段52は圧縮手段55に信号を送って、堆積した塵埃を圧縮する。ここで電源投入時にごみ量を検出しており、そのごみ量が多い場合は、停止操作時に除塵手段57を動作させる動作時間(除塵時間)および圧縮手段を動作させる動作時間(圧縮時間)を長くするように動作する。ここでの圧縮時間とは圧縮板30が下降して塵埃を押し付けている時間のことである。   Then, when the cleaning is finished and the user performs the stop operation of the electric blower 2 by the hand operation means 8, the control means 52 sends a signal to the dust removal means 57 to drive the dust removal motor 58 that rotationally drives the gear. . Further, after a predetermined time has elapsed after the stop operation, the control unit 52 sends a signal to the compression unit 55 to compress the accumulated dust. Here, the amount of dust is detected when the power is turned on, and if the amount of dust is large, the operation time for operating the dust removing means 57 (dust removal time) and the operation time for operating the compression means (compression time) during the stop operation are lengthened. To work. The compression time here is the time during which the compression plate 30 is lowered and the dust is pressed.

次に、集塵容器4内で圧縮された塵埃の廃棄について説明する。   Next, disposal of dust compressed in the dust collecting container 4 will be described.

集塵容器4を集塵容器収納部5から取り外す時は、容器ハンドル12を握って集塵容器4を上方に持上げるだけで良い。そして、集塵容器4をごみ箱などの上に持っていって、容器操作部23を下方に押すと、連結棒46は下がって、尾錠22は外方に移動し、蓋体20と尾錠22との係止が解除され、蓋体20はコイルバネ21の付勢力で開成し、集塵容器4内の圧縮された塵埃は外部へ押し出されごみ箱内に落下する。   When removing the dust collection container 4 from the dust collection container storage part 5, it is only necessary to hold the container handle 12 and lift the dust collection container 4 upward. When the dust collecting container 4 is held on a trash box or the like and the container operating unit 23 is pushed downward, the connecting rod 46 is lowered, the buckle 22 is moved outward, the lid 20 and the buckle 22 The lid 20 is opened by the urging force of the coil spring 21, and the compressed dust in the dust collecting container 4 is pushed out and falls into the trash box.

以上のように、本実施の形態によれば、集塵容器に堆積された塵埃を圧縮手段で押圧して、粗塵フィルター内に堆積した塵埃を圧縮すると共に細塵フィルターに付着した細塵を除塵手段で除塵することで、吸引風の流路を確保して吸引力の低下を抑え、電動送風機の消費電力を抑えることができる。また、集塵捕集手段の集塵量に応じて圧縮手段や除塵手段の動作時間を可変し、集塵容器の集塵量が多く、圧縮および除塵の必要度が高いときには長い時間をかけて確実に圧縮および除塵を行うが、塵埃量が少なく、圧縮および除塵の必要度が低いときには、圧縮手段や除塵手段の動作時間を短縮することで、次の掃除動作に即座に移行できるとともに、除塵機構の信頼性および寿命を向上させることができる。また、圧縮モータのような動力源を用いて塵埃を圧縮するため、従来問題となった綿ゴミのような風量変化の小さい塵埃でも、確実に集塵ごみを圧縮することができる。   As described above, according to the present embodiment, the dust accumulated in the dust collecting container is pressed by the compression means to compress the dust accumulated in the coarse dust filter and to remove the fine dust attached to the fine dust filter. By removing the dust with the dust removing means, it is possible to secure the flow path of the suction air and suppress the reduction of the suction force, thereby reducing the power consumption of the electric blower. Also, the operation time of the compression means and dust removal means can be varied according to the amount of dust collected by the dust collection means, and it takes a long time when the dust collection container has a large amount of dust collection and the need for compression and dust removal is high. Although compression and dust removal are performed reliably, when the amount of dust is small and the need for compression and dust removal is low, the operation time of the compression means and dust removal means can be shortened, so that the next cleaning operation can be performed immediately and the dust removal The reliability and lifetime of the mechanism can be improved. Further, since dust is compressed using a power source such as a compression motor, dust collection dust can be reliably compressed even with dust having a small change in airflow, such as cotton dust, which has been a problem in the past.

(変形例1)
次に、風量検出手段60に関した動作について説明する。
(Modification 1)
Next, the operation related to the air volume detection means 60 will be described.

電動送風機2に接続された風量検出手段60は、電動送風機2を流れる電流を検出することによって、電動送風機2で発生する吸引風の風量を検出する。これは、粗塵フィルター28,29内の集塵量が多くなったり、細塵フィルター43に細塵が溜まり過ぎたりすると吸引風の流れが悪くなり、電動送風機2の負荷が重くなって電動送風機2の電動機部を流れる電流が大きくなる。逆に、粗塵フィルター28,29および細塵フィルター43の通気状態が良好な場合は電動送風機2の負荷が軽くなって電動送風機2の電動機部を流れる電流が少なくなる。風量検出手段60は、このような現象を利用して吸引風の風量を間接的に検出し、吸引風の風量を表す信号を出力する。   The air volume detection means 60 connected to the electric blower 2 detects the air volume of the suction air generated by the electric blower 2 by detecting the current flowing through the electric blower 2. This is because if the amount of collected dust in the coarse dust filters 28 and 29 is increased, or if fine dust accumulates too much in the fine dust filter 43, the flow of suction air becomes worse, the load on the electric blower 2 becomes heavy, and the electric blower The electric current which flows through the motor part 2 increases. On the contrary, when the ventilation state of the coarse dust filters 28 and 29 and the fine dust filter 43 is good, the load of the electric blower 2 is lightened and the current flowing through the electric motor part of the electric blower 2 is reduced. The air volume detection means 60 indirectly detects the air volume of the suction air using such a phenomenon, and outputs a signal representing the air volume of the suction air.

この風量検出手段60が出力する風量を表す信号を受けて動作する制御手段52は、吸引風の風量が少なくなって、電動送風機2を流れる電流が増大した状態で電動送風機2が停止した場合、電動送風機2の停止後に行う圧縮手段55および除塵手段57の動作時間を長くして、圧縮および除塵を確実に行う。逆に、電動送風機2を流れる電流が少ない状態で電動送風機2が停止した場合、圧縮手段55および除塵手段57の動作時間を短くし、圧縮動作及び除塵動作の期間中に禁止される電動送風機2の動作を解除して、掃除動作を再開するまでの時間を短縮することができる。検出した電動送風機2の風量に対して設定する圧縮手段55及び除塵手段57の動作時間の最適値は、電気掃除機の用途によって、電動送風機の大きさや吸引力、集塵フィルター構造等の仕様が異なるため、予め電気掃除機の試作品を製作して実験的に求めればよい。   The control means 52 that operates in response to a signal representing the air volume output by the air volume detection means 60 is such that when the electric blower 2 is stopped in a state in which the current of the electric blower 2 is increased due to a decrease in the air volume of the suction air, The operation time of the compression means 55 and the dust removal means 57 performed after the electric blower 2 is stopped is lengthened, and the compression and the dust removal are reliably performed. On the contrary, when the electric blower 2 stops in a state where the current flowing through the electric blower 2 is small, the operation time of the compression means 55 and the dust removal means 57 is shortened, and the electric blower 2 prohibited during the compression operation and the dust removal operation. It is possible to shorten the time until the cleaning operation is canceled and the cleaning operation is restarted. The optimum values of the operating time of the compression means 55 and the dust removal means 57 set for the detected air volume of the electric blower 2 have specifications such as the size and suction force of the electric blower and the dust collecting filter structure depending on the use of the vacuum cleaner. Since it is different, it is only necessary to produce a prototype of a vacuum cleaner in advance and obtain it experimentally.

なお、上述した変形例1は、集塵量検知手段59の検出信号を用いずに風量検出手段60の検出信号のみに応じて圧縮手段55及び除塵手段57の動作時間を制御する例で説明したが、集塵量検知手段59の検出信号と風量検出手段60の検出信号との両方の信号を用いて圧縮手段55及び除塵手段57の動作時間を設定しても構わない。後者の場合、風量検出手段60と検出信号と圧縮及び除塵動作に必要な動作時間との相関関係、および集塵量検知手段59の検出信号と圧縮及び除塵動作に必要な動作時間との相関関係を予め実験的に求める。それらの相関関係を基にして、風量検出手段60で検出した検出信号レベルに対応した動作時間と、集塵量検知手段59で検出した検出信号レベルに対応した動作時間とを求め、そのうち長い方の動作時間を選択して圧縮手段55及び除塵手段57を動作させる。これにより、圧縮動作と除塵動作とがより確実に行われ、圧縮動作及び除塵動作の信頼性を高めることが出来る。   The first modification described above is an example in which the operation time of the compression unit 55 and the dust removal unit 57 is controlled only in accordance with the detection signal of the air volume detection unit 60 without using the detection signal of the dust collection amount detection unit 59. However, the operation time of the compression means 55 and the dust removal means 57 may be set using both the detection signal of the dust collection amount detection means 59 and the detection signal of the air volume detection means 60. In the latter case, the correlation between the air volume detection means 60 and the detection signal and the operation time required for the compression and dust removal operation, and the correlation between the detection signal of the dust collection amount detection means 59 and the operation time required for the compression and dust removal operation. Is experimentally determined in advance. Based on these correlations, an operation time corresponding to the detection signal level detected by the air volume detection means 60 and an operation time corresponding to the detection signal level detected by the dust collection amount detection means 59 are obtained, and the longer one is obtained. , The compression means 55 and the dust removal means 57 are operated. Thereby, the compression operation and the dust removal operation are more reliably performed, and the reliability of the compression operation and the dust removal operation can be improved.

(変形例2)
次に、タイマー手段64に関した動作について説明する。
(Modification 2)
Next, operations related to the timer means 64 will be described.

タイマー手段64は、制御手段52内で用いられる所定周期のクロック信号を計数して、電動送風機2が動作を開始してから停止するまでの吸引累積時間を求める。このタイマー手段64の信号を受けて動作する制御手段52は、この吸引累積時間の長さに応じて電動送風機2が停止した後に動作させる圧縮手段55および除塵手段57の動作時間を可変する。   The timer means 64 counts a clock signal of a predetermined period used in the control means 52, and obtains a cumulative suction time from when the electric blower 2 starts operating until it stops. The control means 52 that operates in response to the signal of the timer means 64 varies the operating time of the compression means 55 and the dust removal means 57 that are operated after the electric blower 2 is stopped according to the length of the accumulated suction time.

具体的に言えば、単位面積当たりの被掃除面に塵埃が均一に堆積した状況下での標準的な掃除作業時間を予め求め、電動送風機2が動作している間の吸引累積時間を測定し、その累積時間内に捕集する集塵量を推定する訳である。そして、この吸引累積時間が長くなった場合は、粗塵フィルター28,29内に堆積した塵埃量が多くなっている、或いは細塵フィルター43への細塵の付着が進行していると想定されるため、圧縮手段55及び除
塵手段57の動作時間を長くして圧縮動作および除塵動作を確実に行う。逆に、吸引累積時間が短い場合は、塵埃の堆積量が少なく、細塵フィルター43への細塵の付着が少ないものと想定され、電動送風機2が停止した後に行う圧縮手段55の圧縮動作及び除塵手段57の除塵動作の動作時間を短くし、圧縮動作及び除塵動作の期間中に禁止される電動送風機2の動作を解除して、掃除動作を再開するまでの時間を短縮することができる。
Specifically, a standard cleaning operation time under the condition that dust is uniformly deposited on the surface to be cleaned per unit area is obtained in advance, and the cumulative suction time while the electric blower 2 is operating is measured. Therefore, the amount of dust collected during the cumulative time is estimated. If the accumulated suction time becomes longer, it is assumed that the amount of dust accumulated in the coarse dust filters 28 and 29 has increased, or that fine dust has adhered to the fine dust filter 43. Therefore, the operation time of the compression means 55 and the dust removal means 57 is lengthened, and the compression operation and the dust removal operation are surely performed. On the contrary, when the accumulated suction time is short, it is assumed that the amount of accumulated dust is small and the fine dust is not attached to the fine filter 43, and the compression operation of the compression means 55 performed after the electric blower 2 is stopped and The operation time of the dust removal operation of the dust removing means 57 can be shortened, the operation of the electric blower 2 prohibited during the compression operation and the dust removal operation can be canceled, and the time until the cleaning operation can be restarted can be shortened.

なお、上述した変形例2は、集塵量検知手段59の検出信号を用いずに電動送風機2が動作している吸引累積時間を検出するタイマー手段64の検出信号のみに応じて圧縮動作及び除塵動作の動作時間を可変する例で説明したが、集塵量検知手段59の検出信号とタイマー手段64の検出信号との両方を用いて圧縮手段55及び除塵手段57の動作時間を設定しても構わない。後者の場合、電動送風機2が動作している間の吸引累積時間をタイマー手段64で検出し、その吸引累積時間に対応する圧縮及び除塵動作の動作時間と、集塵量検知手段59で検出した集塵量に対応する圧縮及び除塵動作の動作時間とを求め、そのうち長い方の動作時間を選択して圧縮動作および除塵動作の動作時間を設定すれば、より確実に塵埃の圧縮と除塵を行うことが出来る。   In the second modification described above, the compression operation and the dust removal are performed only in accordance with the detection signal of the timer means 64 that detects the accumulated suction time during which the electric blower 2 is operating without using the detection signal of the dust collection amount detection means 59. Although the example in which the operation time of the operation is variable has been described, the operation time of the compression unit 55 and the dust removal unit 57 may be set using both the detection signal of the dust collection amount detection unit 59 and the detection signal of the timer unit 64. I do not care. In the latter case, the accumulated suction time while the electric blower 2 is operating is detected by the timer means 64, and the operation time of the compression and dust removal operation corresponding to the accumulated suction time and the dust collection amount detecting means 59 are detected. If the operation time of compression and dust removal operation corresponding to the amount of dust collected is obtained, and the longer operation time is selected and the operation time of compression operation and dust removal operation is set, dust compression and dust removal is performed more reliably. I can do it.

なお、上述した実施の形態では、風量検出手段60は、電動送風機2を流れる電流の検出値から電動送風機2の風量を間接的に検出するもので説明したが、電動送風機2が発生する吸引風の風量を直接検出する手段を用いても構わない。また、タイマー手段64と制御手段52を独立して回路構成するものとしたが、制御手段52の中にタイマー手段64を内蔵させて実施しても構わない。   In the above-described embodiment, the air volume detection means 60 is described as indirectly detecting the air volume of the electric blower 2 from the detected value of the current flowing through the electric blower 2, but the suction air generated by the electric blower 2 is described. Means for directly detecting the air volume may be used. In addition, although the timer unit 64 and the control unit 52 are configured as independent circuits, the timer unit 64 may be built in the control unit 52.

この実施の形態で用いる集塵量検知手段59aは、塵埃検出手段70、分別信号出力手段71、第1の塵埃計数手段76及び第2の塵埃計数手段77によって構成される。   The dust collection amount detection means 59a used in this embodiment is constituted by a dust detection means 70, a classification signal output means 71, a first dust counting means 76, and a second dust counting means 77.

塵埃検出手段70は、吸気経路内の接続部(例えば、先端パイプ)9に配置され、その吸気経路内を通過する塵埃を検出するものであり、赤外発光ダイオード(図示せず)とフォトトランジスタ(図示せず)などで構成される。   The dust detection means 70 is disposed at a connection portion (for example, a tip pipe) 9 in the intake path, and detects dust passing through the intake path, and includes an infrared light emitting diode (not shown) and a phototransistor. (Not shown).

分別信号出力手段71は、塵埃検出手段70の出力信号を複数の増幅率で増幅して塵埃の大きさ判別することが可能なものであり、増幅機能とローパスフィルター機能を持たせたオペレーショナルアンプで構成される第1の増幅手段72と、第1の増幅手段72で増幅した信号をパルス信号に変換するコンパレータで構成された第1のパルス変換手段73と、第1の増幅手段72よりも大きな増幅率を有したオペレーショナルアンプで構成される第2の増幅手段74と、第2の増幅手段74で増幅された信号をパルス信号に変換するコンパレータで構成された第2のパルス変換手段75と、によって構成される。そして、第1の増幅手段72では高域周波数の信号成分が減衰するため、第1のパルス変換手段73は大きな塵埃に相当する信号のみをパルス変換することになり、第1のパルス変換手段73の出力から第1の塵埃検出信号(大きな塵埃の検出信号)を出力する。また、第2の増幅手段74は高い増幅率で信号を増幅するため、大きな塵埃の検出信号も小さな塵埃の検出信号も増幅することができ、第2のパルス変換手段75は大きなものも小さなものも含む塵埃の検出信号をパルス変換して第2のパルス変換手段75の出力から第2の塵埃検出信号を出力する。   The classification signal output means 71 can amplify the output signal of the dust detection means 70 with a plurality of amplification factors to determine the size of the dust, and is an operational amplifier having an amplification function and a low-pass filter function. The first amplifying means 72 configured, the first pulse converting means 73 configured by a comparator that converts the signal amplified by the first amplifying means 72 into a pulse signal, and larger than the first amplifying means 72. A second amplifying unit 74 configured by an operational amplifier having an amplification factor; a second pulse converting unit 75 configured by a comparator that converts a signal amplified by the second amplifying unit 74 into a pulse signal; Consists of. Since the high frequency signal component is attenuated in the first amplifying means 72, the first pulse converting means 73 performs pulse conversion only on the signal corresponding to large dust, and the first pulse converting means 73 is used. The first dust detection signal (large dust detection signal) is output from the output. Further, since the second amplifying means 74 amplifies the signal with a high amplification factor, it is possible to amplify both large dust detection signals and small dust detection signals, and the second pulse conversion means 75 is large and small. The second dust detection signal is output from the output of the second pulse conversion means 75 by pulse-converting the dust detection signal including the first dust conversion signal.

第1の塵埃計数手段76は第1の塵埃検出信号を受けて大きな塵埃の検出信号の数をカ
ウントする。第2の塵埃計数手段77は第2の塵埃検出信号を受けて、大きなものも小さなものも含んだ塵埃の検出信号をカウントする。
The first dust counting means 76 receives the first dust detection signal and counts the number of large dust detection signals. The second dust counting means 77 receives the second dust detection signal and counts dust detection signals including both large and small ones.

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.

掃除機本体1を商用電源(図示せず)に接続し、電源投入時の圧縮動作および除塵動作を行う。その後、使用者は手元操作手段8によって運転を指示すると、手元操作手段8から制御手段52に操作信号が送られ、操作された内容にしたがって、制御手段52は運転が行われるように駆動手段54へ駆動信号を送る。駆動手段54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は回転動作を開始して、吸引力(吸引風)を発生する。   The vacuum cleaner main body 1 is connected to a commercial power source (not shown), and a compression operation and a dust removal operation are performed when the power is turned on. Thereafter, when the user instructs driving by the hand operating means 8, an operation signal is sent from the hand operating means 8 to the control means 52, and the driving means 54 is operated so that the control means 52 is driven according to the operated content. Send drive signal to. The drive means 54 energizes the electric blower 2 according to the transmitted signal, and the electric blower 2 starts rotating to generate suction force (suction air).

吸引された塵埃は、ホース3を経て掃除機本体1内の集塵容器4へ集塵される。塵埃が吸引される期間、吸気経路内の接続部9を塵埃が通過し、発光部(発光ダイオード)と受光部(フォトトランジスタ)の間を塵埃が通過する度に受光量が変化し、塵埃検出手段11の受光部電圧が変化するので、塵埃検出手段70は分別信号出力手段71に検出信号を伝達する。分別信号出力手段71は、受けた信号を第1の増幅手段72および第2の増幅手段74で増幅する。第1のパルス変換手段73は、増幅した信号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パルス出力する。第2のパルス変換手段75は、第2の増幅手段74で増幅した信号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パルス出力する。   The sucked dust is collected in the dust collecting container 4 in the cleaner body 1 through the hose 3. During the period when dust is sucked in, dust passes through the connection part 9 in the intake path, and the amount of received light changes each time the dust passes between the light emitting part (light emitting diode) and the light receiving part (phototransistor). Since the light receiving unit voltage of the means 11 changes, the dust detection means 70 transmits a detection signal to the classification signal output means 71. The classification signal output unit 71 amplifies the received signal by the first amplification unit 72 and the second amplification unit 74. The first pulse converter 73 outputs a pulse as a first dust detection signal if the amplified signal exceeds a predetermined threshold. The second pulse conversion means 75 outputs a pulse as a second dust detection signal if the signal amplified by the second amplification means 74 exceeds a predetermined threshold.

比較的大きな塵埃の場合には、第1,第2のパルス変換手段73,75の出力端子から第1の塵埃検出信号、第2の塵埃検出信号がともに出力され、大きな塵埃を対象とする第1増幅率(小さい増幅率)でも反応したと判定できる。そして、小さな塵埃の場合には、大きな塵埃を対象とする第1増幅率(小さい増幅率)では判定レベルに達せず、第2のパルス変換手段75のみがパルス変換動作を行って、第2のパルス変換手段75の出力端子から第2の塵埃検出信号のみが検出され、小さな塵埃を対象とする第2増幅率(大きい増幅率)でのみ反応したと判定できる。即ち、増幅率の異なる2つの増幅手段(72,74)の信号を分別することで、塵埃検出手段70の受発光部を通過する通過速度が等しく、パルス幅の差異では識別できない塵埃(例えば径が0.1mmの塵埃と0.03mmの塵埃)の信号であっても、信号として識別することができるという効果が得られる。その効果は、第1の増幅手段72にローパスフィルター機能を持たせることにより、より強調することができる。   In the case of relatively large dust, both the first dust detection signal and the second dust detection signal are output from the output terminals of the first and second pulse conversion means 73 and 75, and the first target for large dust is output. It can be determined that the reaction has occurred even with one amplification factor (small amplification factor). In the case of small dust, the first amplification factor (small amplification factor) for large dust does not reach the determination level, and only the second pulse conversion means 75 performs the pulse conversion operation, and the second amplification factor 75 Only the second dust detection signal is detected from the output terminal of the pulse conversion means 75, and it can be determined that the reaction has occurred only at the second amplification factor (large amplification factor) for small dust. That is, by separating the signals of the two amplifying means (72, 74) having different amplification factors, the dust (for example, the diameter) that the passage speeds passing through the light receiving and emitting parts of the dust detecting means 70 are equal and cannot be identified by the difference in pulse width Even if it is a signal of 0.1 mm dust and 0.03 mm dust), it is possible to identify the signals as signals. The effect can be further emphasized by providing the first amplifying means 72 with a low-pass filter function.

次に、第1の塵埃計数手段76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中にカウントし、そのカウント結果を制御手段52へ送り、第2の塵埃計数手段77は第2の塵埃検出信号を同様に所定単位時間中にカウントし、そのカウント結果を制御手段52へ送る。制御手段52は、第1の塵埃計数手段76の計数結果と第2の塵埃計数手段77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ていく。この積算値が予め設定している所定の基準値以上になると、制御手段52は、集塵容器4内の集塵量が所定値以上になったものとして総塵埃量の積算値の情報を記憶手段78に記憶させる。制御手段52は、この集塵量を判定する基準値を複数のレベルに設定しておき、電動送風機2を停止した時の集塵量のレベルを判断し、その集塵量のレベルに応じて電動送風機2の停止後に行う圧縮動作および除塵動作の動作時間を可変する。   Next, the first dust counting means 76 counts the first dust detection signal during a predetermined unit time set in advance, sends the count result to the control means 52, and the second dust counting means 77 Similarly, the dust detection signal is counted during a predetermined unit time, and the count result is sent to the control means 52. The control means 52 integrates the value of the count result of the first dust count means 76 and the count result of the second dust count means 77 as a total dust amount at a triple ratio, for example. When this integrated value is equal to or greater than a predetermined reference value set in advance, the control means 52 stores information on the integrated value of the total dust amount as the dust collection amount in the dust container 4 is equal to or greater than the predetermined value. The data is stored in the means 78. The control means 52 sets the reference value for determining the dust collection amount to a plurality of levels, determines the level of the dust collection amount when the electric blower 2 is stopped, and according to the level of the dust collection amount. The operation time of the compression operation and the dust removal operation performed after the electric blower 2 is stopped is varied.

この情報が記憶手段78に記憶された状態で、掃除動作を終了するために使用者が停止操作を行ったときに、制御手段52は、除塵手段57に信号を送って、ギヤを回転駆動する除塵モータ58を駆動する。さらに所定時間経過後には圧縮手段55に信号を送って、塵埃を圧縮する。ここで制御手段52は総塵埃量を検出しており、そのごみ量が多くなる
と、停止操作後の除塵手段57の動作時間および圧縮手段の動作時間(圧縮時間)を長くするように動作する。ここでの圧縮時間とは、圧縮板30が下降してロック状態で塵埃を押し付けている時間のことである。
With this information stored in the storage means 78, when the user performs a stop operation to end the cleaning operation, the control means 52 sends a signal to the dust removal means 57 to drive the gears to rotate. The dust removal motor 58 is driven. Further, after a predetermined time has elapsed, a signal is sent to the compression means 55 to compress the dust. Here, the control means 52 detects the total amount of dust, and when the amount of dust increases, the control means 52 operates to lengthen the operation time of the dust removal means 57 and the operation time (compression time) of the compression means after the stop operation. Here, the compression time is the time during which the compression plate 30 is lowered and the dust is pressed in the locked state.

そして、制御手段52は、集塵量検知手段59aで検知した集塵量が満杯状態であると判断すると、満杯報知手段63で使用者に報知して、集塵容器4内で満杯状態になった塵埃を捨てるように催促する。それでも、使用者が集塵容器4内に溜まったごみを捨てないで掃除作業を完了した場合は、再び電源投入して電気掃除機を動作させた時、記憶手段78に記憶した情報を基に、集塵容器4内の満杯状態を使用者に対して満杯報知手段63で報知する。   When the control unit 52 determines that the dust collection amount detected by the dust collection amount detection unit 59a is full, the control unit 52 notifies the user by the full notification unit 63 and the dust collection container 4 becomes full. Remind you to throw away the dust. Still, when the user completes the cleaning work without throwing away the dust accumulated in the dust collecting container 4, when the user turns on the power again and operates the vacuum cleaner, the information stored in the storage means 78 is used. The full state in the dust collecting container 4 is notified to the user by the full notification means 63.

以上のように動作することで本実施の形態においては、掃除動作終了までの塵埃量の計数によって停止後の圧縮時間および、または除塵時間を可変させることにより、集塵容器の集塵量が多く、圧縮および除塵の必要度が高いときには時間をかけて確実に圧縮および除塵を行うが、塵埃量が少なく比較的必要度が低いときには時間を短縮することで次の掃除動作に容易に移行できるとともに除塵機構の信頼性および寿命を向上させることができる。   By operating as described above, in the present embodiment, the amount of dust collected in the dust collection container is increased by varying the compression time and / or dust removal time after stopping by counting the amount of dust until the end of the cleaning operation. When the necessity of compression and dust removal is high, the compression and dust removal is surely performed over time, but when the amount of dust is small and the necessity is relatively low, the time can be shortened to easily move to the next cleaning operation. The reliability and life of the dust removal mechanism can be improved.

なお、本実施の形態では、ごみ量を赤外発光ダイオードとフォトトランジスタなどで構成された塵埃検出手段70で検出したが、電動送風機2に流れる電流を検出して、ごみが溜まってきた時の電流変化を検出することで、ごみの量を判定しても良い。また、塵埃の大きさによって、圧縮時間および除塵時間を可変させるとさらによいことは言うまでもない。   In the present embodiment, the amount of dust is detected by the dust detection means 70 constituted by an infrared light emitting diode and a phototransistor. However, when the current flowing in the electric blower 2 is detected, The amount of dust may be determined by detecting a current change. Needless to say, the compression time and the dust removal time can be varied according to the size of the dust.

以上のように、本発明の係る電気掃除機は、細塵フィルターと粗塵フィルターを備えた電気掃除機に適用することができる。   As described above, the vacuum cleaner according to the present invention can be applied to a vacuum cleaner including a fine dust filter and a coarse dust filter.
