Description

本発明は、繰り返し使用可能な集塵ケースを使用する電気掃除機に関するものである。   The present invention relates to a vacuum cleaner using a dust collection case that can be used repeatedly.

従来、この種の電気掃除機としては、集塵ケース内に専用のサイクロン気流を発生させて、吸引した空気流より遠心力で塵埃を分離し、集塵ケース内に塵埃を堆積させるようにしたものが知られている(例えば、特許文献1参照)。
特開2000−342492号公報
Conventionally, in this type of vacuum cleaner, a dedicated cyclone air flow is generated in the dust collection case, and dust is separated from the sucked air flow by centrifugal force, and dust is accumulated in the dust collection case. Those are known (for example, see Patent Document 1).
JP 2000-342492 A

しかしながら、前記従来の構成では、集塵ケース内にサイクロン気流を発生させて、吸引した空気流より遠心力で塵埃を分離し、集塵ケース内に塵埃を堆積させるようにしているが、多くは吸込み仕事率を高位に確保する制約から、塵埃を十分に遠心分離できない構成となっている。そのため、集塵ケース内で塵埃が堆積すると、堆積した塵埃自体がフィルタの役割を果たすため、粗塵の堆積部に細塵も付着してこれが通気抵抗となり、急激に吸引力が低下するという課題を有していた。また、サイクロン気流を発生させるために、吸気経路を大きく曲げる必要があり、かつ吸入時に旋回流も発生するため、集塵ケース内で吸入から排気に至る経路での圧力損失が大きくなり、吸込仕事率が低くなるという課題を有していた。   However, in the conventional configuration, a cyclone airflow is generated in the dust collecting case, dust is separated by centrifugal force from the sucked air flow, and dust is accumulated in the dust collecting case. Due to the restriction of ensuring a high suction work rate, the dust cannot be sufficiently centrifuged. Therefore, when dust accumulates in the dust collection case, the accumulated dust itself acts as a filter, so fine dust also adheres to the coarse dust accumulation part, which becomes a ventilation resistance, and the suction force decreases rapidly. Had. In addition, in order to generate a cyclone air flow, the intake path needs to be bent greatly, and a swirling flow is also generated at the time of intake, so the pressure loss in the path from the intake to the exhaust in the dust collection case increases, and the suction work The problem was that the rate would be low.

本発明は、前記従来の課題を解決するもので、高い吸込仕事率を確保しながら、かつ塵埃を吸引しても吸込力が低下しにくい電気掃除機を提供する。   The present invention solves the above-mentioned conventional problems, and provides a vacuum cleaner that secures a high suction work rate and hardly reduces the suction force even when dust is sucked.

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、電動送風機と、前記電動送風機の上流側に設置され前記電動送風機により吸引した塵埃を含む空気を導入する塵埃分離部と、前記塵埃分離部で分離された塵埃を収容する塵埃収容部とを備え、前記塵埃分離部には吸引口から導入する塵埃を含む空気を旋回気流として流す旋回気流通風路を設け、前記旋回気流通風路の少なくとも一部を形成する除塵フィルタを備え、前記除塵フィルタの外周に電動送風機の吸引力が作用する空間を設けた、電気掃除機である。   In order to solve the above-described conventional problems, an electric vacuum cleaner of the present invention includes an electric blower, a dust separation unit that is installed on the upstream side of the electric blower and introduces air containing dust sucked by the electric blower, and A dust containing portion for containing the dust separated by the dust separating portion, and the dust separating portion is provided with a swirling air circulation air passage for flowing air containing dust introduced from the suction port as a swirling air flow, and the swirling air circulation The vacuum cleaner includes a dust removal filter that forms at least a part of an air passage, and a space in which the suction force of the electric blower acts is provided on an outer periphery of the dust removal filter.

このような発明によって、塵埃を含む空気が塵埃分離部に流入する際、塵埃分離部内で旋回気流が発生することになる。ここで、旋回成分をもって流入した塵埃は除塵フィルタ内の円筒中空部でも旋回し、綿ゴミや毛髪などの粗塵は除塵フィルタ内の円筒中空部を旋回しながら下降し、塵埃収容部に導かれる。   With such an invention, when air containing dust flows into the dust separator, a swirling airflow is generated in the dust separator. Here, dust flowing in with a swirling component also swirls in the cylindrical hollow portion in the dust removal filter, and coarse dust such as cotton dust and hair descends while swirling in the cylindrical hollow portion in the dust removal filter, and is guided to the dust container. .

また、除塵フィルタ内の円筒中空部では旋回気流により、内面に塵埃が付着しても剥離するため、除塵フィルタには塵埃が堆積せず通気性を確保できる。つまり、塵埃を吸引しても塵埃は塵埃収容部に堆積し、吸引口から電動送風機に至る吸引経路は除塵フィルタの周囲にわたって確保される。そのため、風量低下を招くことなく、風量維持性能に優れ、長期間のメンテナンス不要の電気掃除機とすることができる。   Further, the cylindrical hollow portion in the dust removal filter peels off even if dust adheres to the inner surface due to the swirling airflow, so that dust does not accumulate on the dust removal filter and air permeability can be secured. That is, even if the dust is sucked, the dust accumulates in the dust container, and a suction path from the suction port to the electric blower is secured around the dust filter. Therefore, it can be set as the vacuum cleaner which is excellent in air volume maintenance performance, and does not require a long-term maintenance, without causing the air volume fall.

また、本発明の電気掃除機では吸引口から電動送風機に至る風路において、急激な気流の曲げや拡大、縮小を繰り返すことなく風路から塵埃を分離するため、高い吸込み仕事率を長期間にわたって確保することができる。   Moreover, in the vacuum cleaner of the present invention, in the air passage from the suction port to the electric blower, dust is separated from the air passage without repeated bending, enlargement, or reduction of the abrupt air current. Can be secured.

従って、本発明の電気掃除機は、高い吸込仕事率を確保しながら、かつ塵埃を吸引しても吸込力が低下しにくく、さらに長期間メンテナンス不要の電気掃除機を提供することができる。   Therefore, the vacuum cleaner of the present invention can provide a vacuum cleaner that does not require maintenance for a long period of time while ensuring a high suction power and is difficult to reduce suction force even when dust is sucked.

That is, even if the dust is sucked, the dust accumulates in the dust container, and a suction path from the suction port to the electric blower is secured around the dust filter. Therefore, it can be set as the vacuum cleaner which is excellent in air volume maintenance performance, and does not require a long-term maintenance, without causing the air volume fall.

また、本発明の電気掃除機では吸引口から電動送風機に至る風路において、急激な気流の曲げや拡大、縮小を繰り返すことなく風路から塵埃を分離するため、高い吸込み仕事率を長期間にわたって確保することができる。   Further, in the vacuum cleaner of the present invention, in the air passage from the suction port to the electric blower, dust is separated from the air passage without repeatedly bending, expanding, and contracting the air current. Can be secured.

このような発明によって、綿ゴミや毛髪などの粗塵は第1の除塵フィルタ内の円筒中空部を旋回しながら下降し、塵埃収容部に導かれ、塵埃収容部に導かれた粗塵は、塵埃収容部から第3の除塵フィルタの方向に吸引されて濾し取られるため、より一層確実に塵埃収容部内で捕捉され堆積する。第3の除塵フィルタを通過した細塵は、第2の除塵フィルタ下端部より流入し、第2の除塵フィルタで濾し取られ、電動送風機側に至る風路を通り除去される。   By such an invention, coarse dust such as cotton dust and hair descends while turning the cylindrical hollow portion in the first dust removal filter, is guided to the dust container, and the coarse dust guided to the dust container is Since it is sucked and filtered from the dust container in the direction of the third dust filter, it is more reliably captured and deposited in the dust container.

よって、粗塵と細塵はより一層効率的に分離され、粗塵は確実に粗塵を塵埃収容部内で捕捉されて堆積する。従って、より一層風量維持性能を確保し、長期間のメンテナンス不要の電気掃除機とすることができる。   Thus, coarse dust and fine dust are more efficiently separated, and the coarse dust is reliably captured and accumulated in the dust container.

Coarse dust and fine dust are separated without passing dust.

第30の発明は、特に第1の発明における除塵フィルタの少なくとも一部は透視部材により形成された、電気掃除機である。   The thirtieth invention is a vacuum cleaner in which at least a part of the dust removal filter in the first invention is formed of a see-through member.

このような発明によって、塵埃の内容物の状態が目視で確認できるため、掃除作業時に誤って塵埃以外のものを吸引した場合でも、容易に発見することができる。   According to such an invention, since the state of the contents of dust can be visually confirmed, even if something other than dust is accidentally sucked during cleaning work, it can be easily found.

本発明の電気掃除機の構成をより具体的に説明すると、床面等の被掃除面の塵埃を吸引する吸込具と、前記吸込具からの塵埃を含む空気を吸引する電動送風機と、この電動送風機を内蔵する電気掃除機本体と、電動送風機により吸引した塵埃を含む空気を導入し、塵埃と空気とに分離する塵埃分離部と、この塵埃分離部で分離された塵埃を収容する塵埃収容部を備える。塵埃分離部は、吸込具からの塵埃を含む空気を導入する吸引口と、この吸引口から導入する塵埃を含む空気を旋回気流として流す旋回気流通風路と、前記旋回気流通風路の少なくとも一部を形成し、塵埃と空気を分離する除塵フィルタを有し、この除塵フィルタの外周を覆うとともに、電動送風機の吸引側へ接続される主風路により、除塵フィルタの外周側から電動送風機の吸引力を作用させた構成とする。   The configuration of the electric vacuum cleaner of the present invention will be described more specifically. A suction tool that sucks dust on a surface to be cleaned such as a floor surface, an electric blower that sucks air containing dust from the suction tool, and this electric motor Vacuum cleaner main body with built-in blower, dust separation part that introduces air containing dust sucked by the electric blower and separates it into dust and air, and dust container part that contains the dust separated by this dust separation part Is provided. The dust separation unit includes a suction port for introducing air containing dust from the suction tool, a swirling air circulation air passage for flowing air containing dust introduced from the suction port as a swirling air current, and at least of the swirling air circulation air passage It has a dust removal filter that forms a part and separates dust and air, covers the outer periphery of this dust removal filter, and the main air passage connected to the suction side of the electric blower from the outer periphery side of the dust removal filter. It is set as the structure which made the suction force act.

旋回気流を発生させるためには、旋回気流通風路を略円筒状、好ましくは円筒状に形成し、その旋回気流通風路の内壁面で、かつ、周方向に沿って旋回する気流が発生するように吸引口を形成する。すなわち、吸引口の吸引方向が、その内壁面の周方向に沿って流れるように円筒状の軸方向と直交する方向で、円筒状の接線方向としている。略円筒状とは、その軸方向と直交する面での断面形状が楕円形状、八角形等の多角形状のものを含み、要は、旋回気流通風路の内壁面の周方向に沿った旋回気流が発生する形状であればよい。   In order to generate a swirling airflow, a swirling air circulation air passage is formed in a substantially cylindrical shape, preferably a cylindrical shape, and an airflow swirling along the circumferential direction is generated on the inner wall surface of the swirling air circulation air passage. A suction port is formed as follows. That is, the suction direction of the suction port is a cylindrical tangential direction in a direction orthogonal to the cylindrical axial direction so as to flow along the circumferential direction of the inner wall surface. The substantially cylindrical shape includes a polygonal shape such as an elliptical shape and an octagonal cross-sectional shape in a plane orthogonal to the axial direction, and in summary, swirling along the circumferential direction of the inner wall surface of the swirling air circulation passage Any shape that generates an airflow may be used.

また、旋回気流通風路に旋回気流が発生するには、当然のことながら旋回気流通風路内に電動送風機の吸引力が作用し、負圧状態を発生させる必要がある。そのため、略円筒状の旋回気流通風路の吸引口を設けた一端側を集塵ケースの天部で覆い、他端側が塵埃収容部と気密に接続し、少なくとも旋回気流通風路に形成した除塵フィルタ部分から電動送風機の吸引力を作用させるようにすればよい。   In order to generate a swirling airflow in the swirling air circulation air passage, it is natural that the suction force of the electric blower acts in the swirling air circulation air passage to generate a negative pressure state. Therefore, the one end side provided with the suction port of the substantially cylindrical swirling air circulation air passage is covered with the top of the dust collecting case, and the other end side is airtightly connected to the dust container, and at least the swirling air circulation air passage is formed. The suction force of the electric blower may be applied from the dust filter portion.

さらに好ましい形態とするには、旋回気流通風路と塵埃収容部との接続部もしくは塵埃収容部そのものに電動送風機の吸引力が作用する副風路を接続するとよい。この構成により、除塵フィルタ部分の吸引力だけでなく、より塵埃収容部に近い箇所での吸引力も得られることになり、除塵フィルタを通過した塵埃がより塵埃収容部へ移動し易くなる。   In order to obtain a more preferable form, it is preferable to connect a sub-air passage in which the suction force of the electric blower acts on a connection portion between the swirling air circulation air passage and the dust housing portion or the dust housing portion itself. With this configuration, not only the suction force of the dust removal filter portion but also the suction force at a location closer to the dust storage portion can be obtained, and the dust that has passed through the dust removal filter is more easily moved to the dust storage portion.

副風路の一端は塵埃収容部の一部に接続し、他端を電動送風機の吸引側へ接続するか、他端を既に形成している主風路の一部に接続するようにしても同様の効果が得られる。副風路の一端側には第3の除塵フィルタを取り付けて、塵埃収容部に溜めた塵埃が電動送風機側へ流れ込まないようにすることが好ましい。特に、副風路を介して電動送風機の吸引力を塵埃収容部側へ作用させるためには、第3の除塵フィルタが目詰まりしにくい構成をとることが好ましい。   One end of the auxiliary air passage is connected to a part of the dust container, and the other end is connected to the suction side of the electric blower, or the other end is connected to a part of the main air passage already formed. Similar effects can be obtained. It is preferable that a third dust removal filter is attached to one end side of the auxiliary air passage so that the dust accumulated in the dust container does not flow into the electric blower side. In particular, in order for the suction force of the electric blower to act on the dust container side through the auxiliary air passage, it is preferable to adopt a configuration in which the third dust removal filter is not easily clogged.

従って、第3の除塵フィルタは粗塵捕集用のフィルタとすることで、目詰まりしにくくして、長期の使用に耐えられるようにすることができる。一方、粗塵フィルタとすることにより細塵が副風路に流れ込む可能性があるので、直接、電動送風機の吸引側に入り込むと電動送風機の耐久性が低下する。そのため、第3の除塵フィルタを粗塵フィルタとする場合には、細塵フィルタを電動送風機の吸引側より上流に設けることが必要である。   Therefore, the third dust removing filter is a filter for collecting coarse dust, so that it is less likely to be clogged and can withstand long-term use. On the other hand, since it is possible that fine dust flows into the auxiliary air passage by using the coarse dust filter, the durability of the electric blower decreases when it directly enters the suction side of the electric blower. Therefore, when the third dust removal filter is a coarse dust filter, it is necessary to provide the fine dust filter upstream from the suction side of the electric blower.

この細塵フィルタに関しては、主風路に位置する除塵フィルタを細塵フィルタとして利用するのであれば、副風路を主風路に接続する方法として、除塵フィルタを構成する細塵フィルタの上流側に位置する主風路に、副風路を接続することがあげられる。この接続により、副風路から細塵を除塵フィルタを構成する細塵フィルタで捕集できる。また、この接続方法により、別途、副風路専用の細塵フィルタを排除することができ、細塵フィルタのメンテナンス性を向上することができる。   As for this fine dust filter, if the dust filter located in the main air passage is used as the fine dust filter, the upstream side of the fine dust filter constituting the dust filter can be used as a method of connecting the sub air passage to the main air passage. A secondary air passage is connected to the main air passage located in With this connection, fine dust can be collected from the auxiliary air passage by the fine dust filter constituting the dust removal filter. In addition, this connection method can eliminate the fine dust filter dedicated to the auxiliary air passage, and improve the maintainability of the fine dust filter.

また、上述した具体的な掃除機では、塵埃分離部に設ける除塵フィルタは旋回気流により自浄効果があるが、除塵フィルタの外周から吸引を行う構成であるので、塵埃による目詰まりを完全に抑制することができない。そのため、除塵フィルタに詰まった塵埃を除去するための塵埃除去手段を設け、掃除機の運転開始時、運転終了時などのタイミングで塵埃除去手段を動作させて、除塵フィルタに詰まった塵埃を除去することが、吸引力、吸込み仕事率を低下させることなく長期使用することを可能にする。   Moreover, in the specific vacuum cleaner mentioned above, although the dust removal filter provided in a dust separation part has a self-cleaning effect by a swirl airflow, since it is the structure which attracts | sucks from the outer periphery of a dust removal filter, clogging by dust is completely suppressed. I can't. Therefore, dust removal means for removing dust clogged in the dust removal filter is provided, and the dust removal means is operated at timing such as when the operation of the vacuum cleaner is started and when the operation is finished, thereby removing the dust clogged in the dust removal filter. Therefore, it can be used for a long time without lowering the suction force and the suction work rate.

塵埃除去手段(除塵手段ともいう)を動作させるタイミングは、実使用の掃除において除塵フィルタにどの程度目詰まりが発生するかを検討し、設計した塵埃分離部の構成、使用する除塵フィルタの種類、形態にあわせて設定することが好ましい。具体的には、運転開始時に一定時間、除塵手段を動作させる、運転終了時に一定時間、除塵手段を動作させる、さらには、運転開始時および終了時の両方に一定時間、除塵手段を動作させる。このようなタイミングで除塵手段を動作させるにはモータを利用することが好ましい。   The timing for operating the dust removal means (also called dust removal means) is to examine how much clogging occurs in the dust filter in actual cleaning, the structure of the designed dust separator, the type of dust filter to be used, It is preferable to set according to the form. Specifically, the dust removing means is operated for a certain time at the start of operation, the dust removing means is operated for a certain time at the end of the operation, and further, the dust removing means is operated for a certain time both at the start and at the end of the operation. In order to operate the dust removing means at such timing, it is preferable to use a motor.

例えば、マイクロコンピュータによるモータのオンオフ制御は簡単に実現でき、掃除機全体の運転制御を司る制御部(一般にはマイクロコンピュータで実現する)の一連の動作の一部として、除塵手段のモータ制御を簡単に組み入れることができる。   For example, on / off control of a motor by a microcomputer can be easily realized, and motor control of dust removing means can be easily performed as part of a series of operations of a control unit (generally realized by a microcomputer) that controls operation of the entire vacuum cleaner. Can be incorporated into.

除塵手段の制御には、上述したモータ使用以外にも、電気掃除機に内蔵されているコード巻取り機構を利用することも考えられる。つまり、使用者が運転開始のためにコード巻き取り機構に巻かれた電源コードを引き出すと、コード巻き取り機構のコード巻き取り部分がその引き出し力によって回転し、この回転力を塵埃除去手段に伝達すれば、運転開始時に塵埃除去手段が動作することになる。また、一般的に、コード巻き取り機構にはゼンマイが内蔵されており、電源コードを引き出すとコード巻き取り機構のコード巻き取り部分が回転し内蔵されたゼンマイを巻くことになる。そして、運転が終了しコードを巻き取るためにコード巻き取り機構の巻き取り釦(一般には電気掃除機の本体の一部に押圧可能に配置されている)を押すと、巻かれたゼンマイの力によりコード巻取り部が電源コードを巻き取り方向に回転し電源コードを巻き取る。この時のコード巻取り部の回転力を塵埃除去手段に伝達すれば、運転終了時に塵埃除去手段を動作させることができる。   In addition to using the motor described above, it is also conceivable to use a cord winding mechanism built in the vacuum cleaner for controlling the dust removing means. That is, when the user pulls out the power cord wound around the cord winding mechanism to start operation, the cord winding portion of the cord winding mechanism rotates by the pulling force, and this rotational force is transmitted to the dust removing means. Then, the dust removing means operates at the start of operation. In general, the cord winding mechanism has a built-in spring, and when the power cord is pulled out, the cord winding portion of the cord winding mechanism rotates to wind the built-in spring. When the winding button of the cord winding mechanism (generally arranged so as to be pressed on a part of the main body of the vacuum cleaner) is pushed to wind the cord after the operation is finished, the power of the wound spring As a result, the cord winding unit rotates the power cord in the winding direction to wind the power cord. If the rotational force of the cord winding portion at this time is transmitted to the dust removing means, the dust removing means can be operated at the end of the operation.

このように、塵埃除去手段を動作させる方法は適宜選択できるが、少なくとも電気掃除機の運転開始時、運転終了時に塵埃除去手段を動作させると、掃除のための運転毎に除塵フィルタの目詰まりを取り除くことができ、掃除運転毎に当初の吸引力、吸込み仕事率の性能を維持できることになる。しかも、除塵フィルタの外周側に吸引力が作用する構成、すなわち、自浄作用により除塵フィルタの目詰まりを抑制できる構成に、上述した塵埃除去手段を採用することにより、その目詰まりが長期にわたり発生せず、長期にわたりメンテナンスを不要とすることができる。また、塵埃除去手段の動作時間も目詰まりしにくい分、その動作時間を短くすることができ、塵埃除去手段をモータで駆動させるものでは、電気掃除機の運転開始時、運転終了時に動作させても、電気掃除機の使用者が掃除動作への移行あるいは後片付けに手間取ることがなく、使い勝手も良好である。   As described above, the method for operating the dust removing means can be selected as appropriate.However, if the dust removing means is operated at least at the start of the operation of the electric vacuum cleaner and at the end of the operation, the dust filter is clogged at every operation for cleaning. It can be removed and the performance of the original suction force and suction work rate can be maintained for each cleaning operation. In addition, by adopting the dust removing means described above in a configuration in which suction force acts on the outer peripheral side of the dust removal filter, that is, a configuration in which clogging of the dust removal filter can be suppressed by self-cleaning, the clogging can occur over a long period of time. Therefore, maintenance can be made unnecessary for a long time. In addition, the operation time of the dust removing means can be shortened because it is less likely to be clogged, and when the dust removing means is driven by a motor, it can be operated at the start of operation of the vacuum cleaner and at the end of operation. However, the user of the vacuum cleaner does not have time to shift to the cleaning operation or clean up, and the usability is also good.

The floor can be moved freely. Further, on the upstream side of the electric blower 21, a dust collection case 5 for introducing air containing dust sucked by the electric blower 21 is detachably attached to the electric vacuum cleaner main body 1 through a partition wall 26 having air permeability. is set up.

また、集塵ケース5は、径の異なる複数の中空円筒を多段に連ねた形状からなり、本実施の形態1では3段構成で、上段から順に、ケース上部22a、ケース中央部22b、塵埃収容部24からなり、このケース上部22aとケース中央部22bとを塵埃分離部23とするものであり、ケース上部22aには塵埃を含む空気を接線方向より導入する吸引口6を備えて構成されている。   The dust collecting case 5 has a shape in which a plurality of hollow cylinders having different diameters are connected in multiple stages. In the first embodiment, the dust collecting case 5 has a three-stage configuration, and in order from the upper stage, the case upper part 22a, the case central part 22b, The case upper portion 22a and the case center portion 22b serve as a dust separation portion 23, and the case upper portion 22a is provided with a suction port 6 for introducing air containing dust from the tangential direction. Yes.

集塵ケース5は、吸引口6から最下段の塵埃を堆積させる塵埃収容部24まで連通されており、吸引口6から電動送風機21に至る風路は、集塵ケース5の塵埃分離部23に設けた開口部25にて電気掃除機本体1の隔壁26と連通させて形成している。さらには塵埃分離部23には、円筒状の除塵フィルタ27を設置している。   The dust collection case 5 communicates from the suction port 6 to the dust container 24 for depositing the lowest level dust, and the air path from the suction port 6 to the electric blower 21 is connected to the dust separation unit 23 of the dust collection case 5. The opening 25 provided is formed so as to communicate with the partition wall 26 of the vacuum cleaner body 1. Furthermore, a cylindrical dust removal filter 27 is installed in the dust separation unit 23.

また、図1に示すように吸引口6には、吸引ホース7、延長管8が順次接続されており、延長管8の先端に吸込具9を取り付けており、電動送風機21を運転することにより、家屋内の床面上の塵埃を吸引することができる。   Further, as shown in FIG. 1, a suction hose 7 and an extension pipe 8 are sequentially connected to the suction port 6, a suction tool 9 is attached to the tip of the extension pipe 8, and the electric blower 21 is operated. The dust on the floor in the house can be sucked.

この円筒状の除塵フィルタ27は、本実施の形態1では、上流側に粗塵フィルタからなる円筒形状の第1の除塵フィルタ27aと、この第1の除塵フィルタより下流側の外周に設けた細塵フィルタからなる円筒形状の第2の除塵フィルタ27bとの2層構造から構成されている。   In the first embodiment, the cylindrical dust removal filter 27 includes a cylindrical first dust removal filter 27a formed of a coarse dust filter on the upstream side and a finer filter provided on the outer periphery on the downstream side of the first dust removal filter. It is comprised from the two-layer structure with the cylindrical 2nd dust removal filter 27b which consists of dust filters.

この第1の除塵フィルタ27aと第2の除塵フィルタ27bの通気部は、集塵ケース5の吸引口6と電動送風機21とが連通する第1の風路である主風路29aの途中に配置している。   The ventilation portions of the first dust removal filter 27a and the second dust removal filter 27b are arranged in the middle of a main air passage 29a that is a first air passage in which the suction port 6 of the dust collecting case 5 and the electric blower 21 communicate with each other. is doing.

また、吸引口6から電動送風機21に至る主風路29aは、第1の除塵フィルタ27a内から第2の除塵フィルタ27b外周の空間全周にわたり設けられている。   The main air passage 29a from the suction port 6 to the electric blower 21 is provided from the first dust filter 27a to the entire outer periphery of the second dust filter 27b.

次に、図3により、集塵ケース5と円筒状の除塵フィルタ27の詳細について説明する。   Next, the details of the dust collection case 5 and the cylindrical dust removal filter 27 will be described with reference to FIG.

図3(a)に示すように、集塵ケース5は、縦型の中空円筒を3段に連ねた形状であり、吸引口6は図3(c)に示すように、ケース上部22aの円周断面の接線方向から気流が流入するように、偏心した位置に配置されている。本実施の形態1では、集塵ケース5を中空円筒としたが、円筒は真円に限定せず楕円形状、8角形や10角形などの多角形形状等でもよく、吸引口6より接線方向から流入した気流が、集塵ケース5の内面に沿って旋回気流が生じる形状であれば良い。また、円筒状の除塵フィルタ27においても同様に、円筒は真円に限定せず楕円形状や8角形や10角形などの多角形形状等でもよく、上記集塵ケース5の内面に沿って発生した旋回気流が、第1の除塵フィルタ27aの円筒中空部においても発生し得る形状であれば良い。   As shown in FIG. 3 (a), the dust collecting case 5 has a shape in which vertical hollow cylinders are arranged in three stages, and the suction port 6 is a circle of the case upper portion 22a as shown in FIG. 3 (c). It arrange | positions in the eccentric position so that airflow may flow in from the tangential direction of a circumferential cross section. In the first embodiment, the dust collecting case 5 is a hollow cylinder, but the cylinder is not limited to a perfect circle, and may be an elliptical shape, a polygonal shape such as an octagonal shape or a decagonal shape. The inflow airflow should just be a shape which a whirling airflow produces along the inner surface of the dust collection case 5. FIG. Similarly, in the cylindrical dust removal filter 27, the cylinder is not limited to a perfect circle, and may be an elliptical shape, a polygonal shape such as an octagonal shape or a 10-sided shape shape, and is generated along the inner surface of the dust collecting case 5. It is sufficient that the swirling airflow has a shape that can be generated in the cylindrical hollow portion of the first dust filter 27a.

従って、塵埃分離部23におけるケース上部22a内面に沿って発生した旋回気流ならびに、第1の除塵フィルタ27aの円筒中空部に発生した旋回気流を形成する通路を旋回気流通風路とするものである。   Accordingly, the swirling air circulation airflow path is a passage that forms the swirling airflow generated along the inner surface of the case upper portion 22a in the dust separation portion 23 and the swirling airflow generated in the cylindrical hollow portion of the first dust removal filter 27a. .

また発生した旋回気流を塵埃収容部24方向に発生させるよう、ケース上部22aに設けた吸引口6の配置は、塵埃分離部23に設けた開口部25の上端部より、吸引口6の下端部が上方になるよう配置されているものである。この様に吸引口6の配置位置を開口部25より高くすることで、吸引口6よりケース上部22aの接線方向より導入された空気は、開口部25側の吸引力作用で下方向である塵埃収容部24方向への旋回気流として発生する。この旋回しながら下降を続ける旋回気流により、綿ゴミなどの粗塵52は風圧を受けて旋回下降し塵埃収容部24に導かれるものである。   In addition, the suction port 6 provided in the case upper portion 22a is arranged at the lower end of the suction port 6 from the upper end of the opening 25 provided in the dust separation unit 23 so that the generated swirling airflow is generated in the direction of the dust container 24. Is arranged so as to be on the upper side. In this way, by arranging the position of the suction port 6 higher than the opening 25, the air introduced from the suction port 6 in the tangential direction of the case upper portion 22a is the dust that is downward due to the suction force action on the opening 25 side. Generated as a swirling airflow in the direction of the accommodating portion 24. Due to the swirling airflow that continues to descend while turning, the coarse dust 52 such as cotton dust receives the wind pressure and turns down to be guided to the dust container 24.

集塵ケース5の下部には、吸引した塵埃を堆積させる塵埃収容部24が設けられており、さらに、塵埃収容部24側の集塵ケース5の底面は、開閉蓋31となっており、ヒンジ32を介して、開閉蓋31を開き、塵埃収容部24内の塵埃を排出できるよう構成されている。   A dust container 24 for depositing the sucked dust is provided at the lower part of the dust collecting case 5, and the bottom surface of the dust collecting case 5 on the dust container 24 side is an open / close lid 31. The opening / closing lid 31 is opened via 32 and the dust in the dust container 24 can be discharged.

また、集塵ケース5は本実施の形態1ではアクリル樹脂により構成されているが、少なくともその一部を透視部材で構成することにより、上方などより内部の塵埃量などを目視で容易に確認できるので好ましい。透明部材としては、ABS、ポリプロピレン、アクリル樹脂などが部材として容易に入手でき、加工性が良い点で好ましい。   The dust collecting case 5 is made of acrylic resin in the first embodiment, but at least a part of the dust collecting case 5 is made of a see-through member, so that the amount of dust inside can be easily confirmed visually from above. Therefore, it is preferable. As the transparent member, ABS, polypropylene, acrylic resin and the like are easily available as a member, which is preferable in terms of good workability.

また、図3(b)に示すように、円筒形状の集塵ケース5の吸引口6と塵埃収容部24の間の内壁には、集塵ケース5と円筒状の除塵フィルタ27間の外側全周にわたり設けた空間部33が形成されており、集塵ケース5内部と電動送風機21の吸引口がこの空間部33を介して連通することとなる。   Further, as shown in FIG. 3B, the outer wall between the dust collection case 5 and the cylindrical dust filter 27 is formed on the inner wall between the suction port 6 of the cylindrical dust collection case 5 and the dust container 24. A space portion 33 provided around the periphery is formed, and the inside of the dust collecting case 5 and the suction port of the electric blower 21 communicate with each other through the space portion 33.

さらに、集塵ケース5のケース上部22aの内面は、円筒状の除塵フィルタ27を構成する内側の第1の除塵フィルタ27aの内面と全体として1つの面となっている。すなわち、集塵ケース5の内面に突出した突起物がない状態となっている。   Further, the inner surface of the case upper portion 22 a of the dust collection case 5 forms one surface as a whole with the inner surface of the inner first dust removal filter 27 a constituting the cylindrical dust removal filter 27. That is, there is no protrusion protruding on the inner surface of the dust collecting case 5.

円筒状の除塵フィルタ27は、図3(d)に示すように、円筒形状の集塵ケース5内部を取り囲むように円筒形状となっている。吸引気流に対して上流側に位置する粗塵フィルタからなる第1の除塵フィルタ27aは、吸引気流中の塵埃から綿埃、毛髪などの比較的サイズの大きい塵埃を除塵するものであり、下流側に位置する細塵フィルタからなる第2の除塵フィルタ27bは、粒子径の細かい砂塵、花粉、ダニ糞などの塵埃を気流中から除塵するものである。   As shown in FIG. 3D, the cylindrical dust removal filter 27 has a cylindrical shape so as to surround the inside of the cylindrical dust collecting case 5. The first dust removing filter 27a composed of a coarse dust filter located upstream from the suction airflow removes relatively large dust such as cotton dust and hair from the dust in the suction airflow. The second dust removing filter 27b made of a fine dust filter located in the position removes dust, such as fine dust particles such as sand dust, pollen, and mite feces, from the airflow.

このように、除塵する塵埃のサイズに応じて複数層の円筒状の除塵フィルタ27を設けることで、除塵フィルタの目詰まりの頻度を低減し、風量持続性能を延ばすことができるが、単一層であっても構わない。   Thus, by providing a plurality of layers of cylindrical dust removal filters 27 according to the size of dust to be removed, the frequency of clogging of the dust removal filter can be reduced and the air flow sustaining performance can be extended. It does not matter.

この第1の除塵フィルタ27aとしては、金属メッシュ、パンチングメタル、樹脂メッシュなど、砂塵などの細塵が通り抜けられる比較的孔径の大きな部材を用いるのが好ましく、本実施の形態1では、特に、通気孔径が250ミクロンの金属メッシュを用いて、第1の除塵フィルタ27a内面の微細な突起を最小限にする構成とした。   As the first dust removing filter 27a, it is preferable to use a member having a relatively large hole diameter through which fine dust such as sand dust can pass, such as a metal mesh, punching metal, resin mesh, and the like in the first embodiment. A metal mesh having a pore diameter of 250 microns was used to minimize the fine protrusions on the inner surface of the first dust filter 27a.

一方、第2の除塵フィルタ27bとしては、不織布、パルプ、ガラス繊維、HEPAフィルタなどを用いることができるが、比較的細かい粒子を効率よく除去できる不織布部材などをプリーツ加工しひだ折りした形状部材を連結し、円筒状に設置することで、通気抵抗を低減しながら、除塵性能を確保することができる。また塵埃付着面に、塵離れがよいPTFEの多孔質部材をコーディングしたフィルタを用いると、第2の除塵フィルタ27bの目詰まりを抑制することができる点でより好ましい。   On the other hand, as the second dust filter 27b, a non-woven fabric, pulp, glass fiber, HEPA filter or the like can be used, but a non-woven fabric member that can efficiently remove relatively fine particles is pleated and folded into a shape member. By connecting and installing in a cylindrical shape, dust removal performance can be ensured while reducing ventilation resistance. In addition, it is more preferable to use a filter in which a porous member of PTFE with good dust separation is used on the dust adhering surface because clogging of the second dust filter 27b can be suppressed.

図4は図3(d)に示す第2の除塵フィルタ27bの一部を拡大した要部断面図である。   FIG. 4 is an enlarged cross-sectional view of a main part of the second dust filter 27b shown in FIG.

本実施の形態1では、図3(d)および図4に示すように、特に、通気孔径が約0.5ミクロンのPTFE膜をPET樹脂で剛性を持たせたシート状のフィルタをプリーツ加工し、ひだ折り形状のフィルタ41にし、両端部を連結して円筒形状にしたものを用いている。   In the first embodiment, as shown in FIGS. 3D and 4, in particular, a sheet-like filter in which a PTFE film having a vent hole diameter of about 0.5 microns is made rigid with PET resin is pleated. A fold-folded filter 41 is used in which both ends are connected to form a cylinder.

なお、ひだ折り形状のフィルタ41の外周部において、吸引気流の上流側にあたるひだ折り形状部材の内面のくぼみ部42は略U字形状にR=2〜5mm程度の丸みを持たせている。尚、ひだ折り形状フィルタ41の第1の除塵フィルタ27aと近接する側のひだには、特にくぼみ部分は持たせてない。   In addition, in the outer peripheral portion of the fold-folded filter 41, the indented portion 42 on the inner surface of the fold-shaped member that corresponds to the upstream side of the suction airflow has a substantially U-shaped roundness of about R = 2 to 5 mm. Note that the folds on the side close to the first dust removal filter 27a of the fold-fold filter 41 are not particularly provided with a recessed portion.

また、第2の除塵フィルタ27bであるひだ折り形状のフィルタ41の外部は、この上端および下端の数mm範囲のみ、樹脂やシール剤等でシールされているシール部43を設け、上下方向からの通気性を遮断している。   In addition, the outside of the fold-folded filter 41 that is the second dust removal filter 27b is provided with a seal portion 43 that is sealed with a resin, a sealant, or the like only within a range of several millimeters at the upper end and the lower end. Air permeability is blocked.

以上のように構成された本実施の形態1の電気掃除機について、図5を基に、その動作を説明する。   About the vacuum cleaner of this Embodiment 1 comprised as mentioned above, the operation | movement is demonstrated based on FIG.

電動送風機21を運転開始すると、吸引気流が発生し、吸込具9、延長管8、吸引ホース7を通じて、空気とともに床面からの塵埃が集塵ケース5内に吸い込まれる。このとき、集塵ケース5の吸引口6は、円筒断面に対して接線方向に偏心して設置されているため、図5(a)に示すように、吸引口6より流入した気流は、集塵ケース5の円筒断面の接線方向から侵入し旋回気流に変化する。   When the electric blower 21 is started to operate, a suction airflow is generated, and dust from the floor surface is sucked into the dust collecting case 5 through the suction tool 9, the extension pipe 8, and the suction hose 7. At this time, since the suction port 6 of the dust collecting case 5 is installed eccentrically in the tangential direction with respect to the cylindrical cross section, as shown in FIG. It enters from the tangential direction of the cylindrical section of the case 5 and changes to a swirling airflow.

ここで、吸引口6の下端は開口部25の上端よりも上部に配置されているため、吸引口6から流入する気流は旋回成分を持つとともに、下方向への成分も持つこととなる。そのため、集塵ケース5のケース上部22aで発生した旋回気流は、旋回しながら下降を続け、円筒状除塵フィルタ27付近に到達する。ここで円筒状除塵フィルタ27の上流側の第1の除塵フィルタ27aは、集塵ケース5内部に向けた突起物がないため、旋回気流の流れを止めることはなく、さらに、気流は旋回を続けながら、図5(b)に示すように、第1の除塵フィルタ27a、第2の除塵フィルタ27bを順次通過し、空間部33を通って、電動送風機21に吸引される。   Here, since the lower end of the suction port 6 is disposed above the upper end of the opening 25, the airflow flowing from the suction port 6 has a swirling component and also has a downward component. Therefore, the swirling airflow generated in the case upper portion 22a of the dust collecting case 5 continues to descend while swirling and reaches the vicinity of the cylindrical dust removal filter 27. Here, the first dust filter 27a upstream of the cylindrical dust filter 27 does not stop the flow of the swirling airflow because there is no protrusion toward the inside of the dust collecting case 5, and the airflow continues to swirl. However, as shown in FIG. 5 (b), the first dust filter 27 a and the second dust filter 27 b are sequentially passed, and are sucked into the electric blower 21 through the space 33.

ここで、吸引気流と一緒に吸引された塵埃は、気流の流れと共に旋回しながら円筒状除塵フィルタ27に導かれ、この塵埃の内、砂塵などの細塵51は、第1の除塵フィルタ27aを通過し、外側の第2の除塵フィルタ27bで濾し取られる。   Here, the dust sucked together with the sucked air flow is guided to the cylindrical dust removing filter 27 while turning along with the air flow, and fine dust 51 such as sand dust among the dust passes through the first dust removing filter 27a. It passes through and is filtered out by the outer second dust filter 27b.

また、比重が軽く、風圧を受けやすい綿埃などの粗塵52は、旋回気流で容易に第1の除塵フィルタ27a表面上から剥離され、図5(b)、(c)に示すように、第1の除塵フィルタ27aの円筒中空部で旋回を続けることとなる。この作用により、第1の除塵フィルタ27aは、気流による自浄作用が働いていることになるため、目詰まりすることなく、吸込力の低下を抑制する。   Further, the coarse dust 52 such as cotton dust that is light in specific gravity and easily receives wind pressure is easily peeled off from the surface of the first dust removing filter 27a by the swirling airflow, and as shown in FIGS. 5 (b) and 5 (c), The turning is continued in the cylindrical hollow portion of the first dust filter 27a. Due to this action, the first dust removing filter 27a has a self-cleaning action due to the airflow, and therefore suppresses a reduction in suction force without clogging.

さらに、吸引する塵埃量が増加していくと、綿埃などの粗塵52は、第1の除塵フィルタ27a内を旋回しながら下降し、塵埃収容部24に導かれる。   Further, when the amount of dust to be sucked increases, coarse dust 52 such as cotton dust descends while turning in the first dust removal filter 27 a and is guided to the dust container 24.

以上から、旋回気流により綿ゴミなどの粗塵52は風圧を受けて旋回下降し塵埃収容部24に導かれ、また、砂塵などの細塵51は第1の除塵フィルタ27aのメッシュの孔を通り抜けるため、第1の除塵フィルタ27aでは塵埃が堆積せず通気性を確保していることになる。   From the above, the coarse dust 52 such as cotton dust is swirled and lowered by the swirling airflow and guided to the dust container 24, and the fine dust 51 such as sand dust passes through the mesh hole of the first dust removing filter 27a. Therefore, the first dust removal filter 27a does not accumulate dust and ensures air permeability.

つまり、塵埃を吸引すると塵埃は確実に細塵51と粗塵52に分離され、細塵51は第2の除塵フィルタ27bで濾し取られ、粗塵52は塵埃収容部24に捕捉されるものであり、吸引口6から電動送風機21に至る吸引経路は、第1および第2の除塵フィルタの周囲にわたって確保されるため風量低下を防ぐことができる。   That is, when dust is sucked, the dust is surely separated into fine dust 51 and coarse dust 52, and the fine dust 51 is filtered by the second dust removing filter 27b, and the coarse dust 52 is captured by the dust container 24. In addition, since the suction path from the suction port 6 to the electric blower 21 is secured around the first and second dust removing filters, it is possible to prevent a decrease in the air volume.

さらに、第2の除塵フィルタ27bにおける吸引気流の上流側にあたるひだのくぼみ部42は、略U字形状に2R〜5R程度の丸みを帯びているものであり、この丸みを帯びることにより、細塵が付着堆積しにくくなり、また、一旦堆積した細塵も剥離除去しやすくなり、フィルタ目詰まりによる風量低下を防止することができる。   Further, the dent indented portion 42 on the upstream side of the suction airflow in the second dust removal filter 27b has a substantially U shape and is rounded by about 2R to 5R. Is less likely to adhere and accumulate, and fine dust once accumulated can be easily peeled and removed, thereby preventing a reduction in air volume due to filter clogging.

そして、集塵ケース5内の塵埃量が増えたときでも、開閉蓋31を開けると、集塵ケース5内部には突起物などの引っかかりがないため、塵埃をスムーズに排出することができ、集塵ケース5自体の手入れも非常に簡単である。   Even when the amount of dust in the dust collection case 5 increases, if the opening / closing lid 31 is opened, the dust collection case 5 does not catch any protrusions and the like, so that the dust can be discharged smoothly. Care of the dust case 5 itself is very simple.

以上の本実施の形態1の電気掃除機を用いて風量維持性能の評価試験を行った。実験方法は、家庭塵埃を篩を用いて綿ゴミと細塵に分離し、綿ゴミを4g、細塵を3g混合し、1回につき7g吸引させて風量の変化を調べた。その結果を図6に示す。なお、対照実験としては市販されているサイクロン式電気掃除機を用いた。   The air quantity maintenance performance evaluation test was performed using the electric vacuum cleaner of the first embodiment. In the experiment method, household dust was separated into cotton dust and fine dust using a sieve, 4 g of cotton dust and 3 g of fine dust were mixed, and 7 g was sucked at a time to examine the change in the air volume. The result is shown in FIG. As a control experiment, a commercially available cyclone vacuum cleaner was used.

図6に示すように、本実施の形態1では初期から高い風量を維持し、また、80g吸引しても初期風量の90%以上維持していたのに対して、対照実験のものは初期から風量が低く、また風量低下のスピードも早く、60g吸引した状態で初期風量の80%以下となった。   As shown in FIG. 6, in the first embodiment, a high air volume was maintained from the beginning, and 90% or more of the initial air volume was maintained even after suction of 80 g, whereas in the control experiment, the initial air volume was maintained. The air volume was low and the speed of air flow reduction was fast, and it was 80% or less of the initial air volume after sucking 60 g.

さらに、吸込み仕事率を測定したところ、本実施の形態1のものは、対照実験のものよりも100W以上高いものであった。   Furthermore, when the suction work rate was measured, the thing of this Embodiment 1 was 100 W or more higher than the thing of the control experiment.

このように本実施の形態1の電気掃除機では、吸引口から電動送風機に至る風路において、急激な気流の曲げや拡大、縮小を繰り返すことなく風路から塵埃を分離するため、吸込み仕事率を高位に確保し、塵埃を吸引しても吸込力が低下しにくい電気掃除機を提供することができる。   Thus, in the vacuum cleaner of this Embodiment 1, in the air passage from the suction port to the electric blower, dust is separated from the air passage without repeatedly bending, expanding, and contracting the air current. Can be provided at a high level, and a vacuum cleaner can be provided in which the suction force does not easily decrease even when dust is sucked.

なお、本実施の形態1では、第2の除塵フィルタ27bを、第1の除塵フィルタ27aの全周に設けたが、図7の斜視図および図8の断面図に示すように、全周囲でなくとも、第2の除塵フィルタ27bを、電動送風機の吸引側のみに配置したものでも同様の効果が認められる。   In the first embodiment, the second dust filter 27b is provided on the entire circumference of the first dust filter 27a. However, as shown in the perspective view of FIG. 7 and the sectional view of FIG. Even if the second dust filter 27b is disposed only on the suction side of the electric blower, the same effect can be recognized.

また、図9(a)の破線部分および図9(b)に示すように、円筒状の除塵フィルタ27に切り欠きを作り、この切り欠き部分に透明の円弧状の透視部材をはめ込み覗き窓91を設けることで、集塵ケース5内に堆積した塵埃の縦方向の断面を目視で確認することができ、掃除作業時に誤って塵埃以外のものを吸引した場合に、発見がより容易になる。   Further, as shown in the broken line part of FIG. 9A and FIG. 9B, a notch is formed in the cylindrical dust removal filter 27, and a transparent arc-shaped fluoroscopic member is fitted into the notch part, and a viewing window 91 is provided. By providing this, it is possible to visually check the vertical cross-section of the dust accumulated in the dust collecting case 5, and it is easier to find when something other than dust is accidentally sucked during the cleaning operation.

(実施の形態2)
次に本発明の実施の形態2について説明する。以下では、実施の形態1の構成、動作との相違点を中心に述べ、実施の形態1と同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 2)
Next, a second embodiment of the present invention will be described. In the following, differences from the configuration and operation of the first embodiment will be mainly described, and the same elements as those in the first embodiment will be denoted by the same reference numerals and description of the configuration and operation will be omitted.

図10、図11に実施の形態2における電気掃除機および集塵ケース5の断面図を示す。   10 and 11 are sectional views of the electric vacuum cleaner and the dust collecting case 5 in the second embodiment.

図10、図11に示すように、実施の形態1との相違点は、集塵ケース5内には、円筒状の除塵フィルタ27に加えて、この円筒状の除塵フィルタ27の下方に配置した中空円板状の第3の除塵フィルタ28を設置していることである。   As shown in FIGS. 10 and 11, the difference from the first embodiment is that the dust collection case 5 is arranged below the cylindrical dust filter 27 in addition to the cylindrical dust filter 27. That is, a hollow disc-shaped third dust filter 28 is provided.

この第3の除塵フィルタ28は、粗塵フィルタからなるもので、第1の除塵フィルタ21と同様に通気孔径が250ミクロンの金属メッシュで作製され、内端が第1の除塵フィルタ27aの周端と隙間なく当接し、外端は第2の除塵フィルタ27bの下端側の外周囲のシール部43まで覆う様に、シール部43および集塵ケース5の塵埃収容部24に隙間なく当接して配置されている。そして、吸引口6からの空気を、第1の除塵フィルタ27aの円筒中空部、および塵埃収容部24を経て、この第3の除塵フィルタ28を介して第2の除塵フィルタ27bの下端部に流れる第2の風路である副風路29bの途中に、この第3の除塵フィルタ28が設けられている。   The third dust removal filter 28 is a coarse dust filter, and is made of a metal mesh having a vent hole diameter of 250 microns, like the first dust removal filter 21, and has an inner end that is a peripheral end of the first dust removal filter 27a. The outer end is disposed in contact with the seal portion 43 and the dust container 24 of the dust collecting case 5 without any gap so as to cover the outer peripheral seal portion 43 on the lower end side of the second dust filter 27b. Has been. Then, the air from the suction port 6 flows to the lower end portion of the second dust removing filter 27b through the third dust removing filter 28 through the cylindrical hollow portion of the first dust removing filter 27a and the dust accommodating portion 24. The third dust filter 28 is provided in the middle of the sub air passage 29b that is the second air passage.

このように、第1の除塵フィルタ27aと第2の除塵フィルタ27bおよび第3の除塵フィルタ28は、集塵ケース5の吸引口6と電動送風機21とが連通する主風路29aもしくは副風路29bに配置している。   Thus, the first dust filter 27a, the second dust filter 27b, and the third dust filter 28 are the main air passage 29a or the sub air passage where the suction port 6 of the dust collecting case 5 and the electric blower 21 communicate with each other. 29b.

以上のように構成された電気掃除機について、図12を基に、その動作を説明する。   About the vacuum cleaner comprised as mentioned above, the operation | movement is demonstrated based on FIG.

電動送風機21を運転開始すると、吸引気流が発生し、吸込具9、延長管8、吸引ホース7を通じて、床面からの塵埃が集塵ケース5内に吸い込まれる。このとき、集塵ケース5の吸引口6は、円筒断面に対して接線方向に偏心して設置されているため、図12(a)に示すように、吸引口6より流入した気流は、集塵ケース5の円筒断面の接線方向から侵入し旋回気流に変化する。   When the electric blower 21 is started to operate, a suction airflow is generated, and dust from the floor surface is sucked into the dust collecting case 5 through the suction tool 9, the extension pipe 8, and the suction hose 7. At this time, since the suction port 6 of the dust collection case 5 is installed eccentrically in the tangential direction with respect to the cylindrical cross section, as shown in FIG. It enters from the tangential direction of the cylindrical cross section of the case 5 and changes to a swirling airflow.

ここでも、吸引口6の下端は開口部25の上端よりも上部に配置されているため、吸引口6から流入する気流は旋回成分を持つとともに、下方向への成分も持つこととなる。そのため、集塵ケース5のケース上部22aで発生した旋回気流は、旋回しながら下降を続け、円筒状の除塵フィルタ27付近に到達する。ここで円筒状の除塵フィルタ27の上流側の第1の除塵フィルタ27aは、集塵ケース5内部に向けた突起物がないため、旋回気流の流れを止めることはなく、さらに、気流は旋回を続けながら図12(b)に示すように、第1の除塵フィルタ27a、第2の除塵フィルタ27bを順次通過し、空間部33を通って、電動送風機21に吸引される。   Again, since the lower end of the suction port 6 is disposed above the upper end of the opening 25, the airflow flowing from the suction port 6 has a swirling component and also has a downward component. Therefore, the swirling airflow generated in the case upper portion 22a of the dust collecting case 5 continues to descend while swirling and reaches the vicinity of the cylindrical dust removal filter 27. Here, the first dust removal filter 27a on the upstream side of the cylindrical dust removal filter 27 does not stop the flow of the swirling airflow because there is no protrusion toward the inside of the dust collecting case 5, and further, the airflow swirls. As shown in FIG. 12 (b), the first dust removing filter 27 a and the second dust removing filter 27 b are sequentially passed through and sucked into the electric blower 21 through the space 33.

ここで、吸引気流と一緒に吸引された塵埃は、気流の流れと共に旋回しながら円筒状の除塵フィルタ27に導かれ、この塵埃の内、砂塵などの細塵51は、第1の除塵フィルタ27aを通過し、外側の第2の除塵フィルタ27bで濾し取られる。   Here, the dust sucked together with the sucked air flow is guided to the cylindrical dust removing filter 27 while swirling along with the air flow, and the fine dust 51 such as sand dust among the dust is the first dust removing filter 27a. And is filtered by the outer second dust removing filter 27b.

また、比重が軽く、風圧を受けやすい綿埃などの粗塵52は、旋回気流で容易に第1の除塵フィルタ27a表面上から剥離され、図12(b)、(c)に示すように、第1の除塵フィルタ27aの円筒中空部で旋回を続けることとなる。この作用により、第1の除塵フィルタ27aは、気流による自浄作用が働いていることになるため、目詰まりすることなく、吸込力の低下を抑制する。   In addition, the coarse dust 52 such as cotton dust having a low specific gravity and easy to receive wind pressure is easily peeled off from the surface of the first dust removing filter 27a by the swirling airflow, and as shown in FIGS. The turning is continued in the cylindrical hollow portion of the first dust filter 27a. Due to this action, the first dust removing filter 27a has a self-cleaning action due to the airflow, and therefore suppresses a reduction in suction force without clogging.

さらに、吸引する塵埃量が増加していくと、綿埃などの粗塵52は、第1の除塵フィルタ27a内を旋回しながら下降し、塵埃収容部24に導かれる。   Further, when the amount of dust to be sucked increases, coarse dust 52 such as cotton dust descends while turning in the first dust removal filter 27 a and is guided to the dust container 24.

塵埃収容部24に導かれた粗塵52は、塵埃収容部24の上部に配置された第3の除塵フィルタ28を介して第2の除塵フィルタ27b端部のひだのくぼみ部42の方向に吸引されるため、塵埃収容部24内に確実に捕捉され堆積すると共に、粗塵52に対し圧縮作用が働き体積収縮が図れるものである。   The coarse dust 52 guided to the dust container 24 is sucked in the direction of the fold recess 42 at the end of the second dust filter 27b through the third dust filter 28 disposed at the top of the dust container 24. As a result, the dust container 24 is surely captured and deposited, and a compressive action is exerted on the coarse dust 52 to reduce the volume.

また、副風路29bが無ければ、集塵ケース5より上流側で吸気経路を塞がれた際、ゴミ収納部24内のゴミはほとんど舞い上がり第1の除塵フィルタ27aの内面に再付着することとなり、この副風路29bをゴミ収納部24を介して主風路29aと連通することにより、上流側で吸気経路を塞がれた際、この副風路29bがバイパス通路となり、前記ごみの舞い上がりを未然に防止できるものである。   Further, if there is no auxiliary air passage 29b, when the intake passage is blocked on the upstream side of the dust collecting case 5, the dust in the dust storage portion 24 almost rises and reattaches to the inner surface of the first dust filter 27a. By connecting the auxiliary air passage 29b to the main air passage 29a through the dust storage portion 24, when the intake passage is blocked on the upstream side, the auxiliary air passage 29b becomes a bypass passage, It is possible to prevent soaring in advance.

このとき、第1の除塵フィルタ27aでは、旋回気流により綿ゴミなどの粗塵52は風圧を受けて旋回下降し、また、砂塵などの細塵51は第1の除塵フィルタ27aのメッシュの孔を通り抜けるため、塵埃が堆積せず通気性を確保している。   At this time, in the first dust removing filter 27a, the coarse dust 52 such as cotton dust is swung down due to the swirling airflow, and the fine dust 51 such as sand dust is passed through the mesh hole of the first dust removing filter 27a. Because it passes through, dust does not accumulate and air permeability is secured.

また、第3の除塵フィルタ28は、金属メッシュで作製され、内端が第1の除塵フィルタの周端と隙間なく当接し、外端は第2の除塵フィルタ27bの下端側の外周囲に備えたシール部43に隙間なく当接して配置されているため、塵埃収容部24内の粗塵52に混ざった細塵51は、第3の除塵フィルタ28を通過した後、第2の除塵フィルタ27bで濾し取られる。   The third dust removal filter 28 is made of a metal mesh, the inner end is in contact with the circumferential end of the first dust removal filter without a gap, and the outer end is provided on the outer periphery on the lower end side of the second dust removal filter 27b. The fine dust 51 mixed with the coarse dust 52 in the dust container 24 passes through the third dust filter 28 and then passes through the second dust filter 27b. Filtered off.

つまり、塵埃を吸引すると塵埃は確実に細塵51と粗塵52に分離され、細塵51は第2の除塵フィルタ27bで濾し取られ、粗塵52は確実に塵埃収容部24に捕捉されるものであり、吸引口6から電動送風機21に至る吸引経路は、第1および第2の除塵フィルタの周囲にわたって確保されるため風量低下を防ぐことができる。   In other words, when dust is sucked, the dust is surely separated into fine dust 51 and coarse dust 52, the fine dust 51 is filtered by the second dust removing filter 27b, and the coarse dust 52 is reliably captured by the dust container 24. Since the suction path from the suction port 6 to the electric blower 21 is secured around the first and second dust removing filters, a reduction in the air volume can be prevented.

実施の形態2でも、実施の形態1と同様の風量維持性能の評価試験を行った。   In the second embodiment, the same air volume maintenance performance evaluation test as in the first embodiment was performed.

その結果は、図13に示すように、本実施の形態2では、実施の形態1よりも風量維持性能に優れていることがわかる。   As a result, as shown in FIG. 13, it is understood that the second embodiment is superior in the air volume maintenance performance to the first embodiment.

このように、実施の形態1に加えて、第3の除塵フィルタ28を集塵ケース5内に配置することにより、粗塵は塵埃収容部24内に確実に捕捉され堆積するため、さらに風量低下を防止し、有用な電気掃除機とすることができる。   As described above, in addition to the first embodiment, by arranging the third dust removal filter 28 in the dust collecting case 5, coarse dust is reliably captured and accumulated in the dust container 24, and thus the air flow rate is further reduced. Can be made into a useful vacuum cleaner.

なお、本実施の形態3では、第2の除塵フィルタ27bおよび第3の除塵フィルタ28を、第1の除塵フィルタ27aの全周に設けたが、実施の形態1と同様に、全周囲でなくとも、第2の除塵フィルタ27b、第3の除塵フィルタ28を、電動送風機の吸引側のみに配置したものでも(図示なし)同様の効果が認められる。   In the third embodiment, the second dust removing filter 27b and the third dust removing filter 28 are provided on the entire circumference of the first dust removing filter 27a. However, as in the first embodiment, not the entire circumference. In both cases, the same effect is recognized even when the second dust filter 27b and the third dust filter 28 are disposed only on the suction side of the electric blower (not shown).

(実施の形態3)
次に本発明の実施の形態3について説明する。以下では、実施の形態1、2の構成、動作との相違点を中心に述べ、同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 3)
Next, a third embodiment of the present invention will be described. In the following, differences from the configurations and operations of the first and second embodiments will be mainly described, and the same components are denoted by the same reference numerals, and description of the configurations and operations will be omitted.

図14は円筒状の除塵フィルタ27の一部の近傍を上方より見た要部断面図である。その他については、実施の形態2と同様である。   FIG. 14 is a cross-sectional view of a main part when a part of the cylindrical dust filter 27 is viewed from above. Others are the same as in the second embodiment.

図14に示す様に、円筒状の除塵フィルタ27を構成する第2の除塵フィルタ27bの上部外周のシール部43には、駆動歯車141が設けられており、この駆動歯車141と嵌合する別の駆動歯車142と、この駆動歯車142を回転駆動させる回転モータ143とにより、第2の除塵フィルタ27bおよび第1の除塵フィルタ27aが一体となって回転する。   As shown in FIG. 14, a drive gear 141 is provided in the seal portion 43 on the upper outer periphery of the second dust filter 27 b constituting the cylindrical dust filter 27, and another drive gear 141 is fitted. The second dust removal filter 27b and the first dust removal filter 27a rotate together by the drive gear 142 and the rotation motor 143 that rotates the drive gear 142.

尚、このように第1の除塵フィルタ27aおよび第2の除塵フィルタ27bが両方とも回転する様に構成しても良いし、第2の除塵フィルタ27bのみが回転する構成としてもよいし、あるいは第1の除塵フィルタ27aに上記駆動歯車141を備えて、上記と同様に駆動歯車142と回転モータ143とにより第1の除塵フィルタ27aのみが回転する様に構成しても良い。   The first dust filter 27a and the second dust filter 27b may both be configured to rotate, or only the second dust filter 27b may be configured to rotate, or the first dust filter 27b may be configured to rotate. One dust removal filter 27a may be provided with the drive gear 141, and the first dust removal filter 27a may be rotated by the drive gear 142 and the rotary motor 143 as described above.

この第1の除塵フィルタ27aおよび第2の除塵フィルタ27bが回転モータ143の駆動により回転することによって、第1の除塵フィルタ27a、及び第2の除塵フィルタ27bの場所によって塵埃の付着量が片寄り一定でない状態、つまり電動送風機2の吸引力が強く働く隔壁26の近傍に塵埃が多く付着する状態を防ぐことができる。そして、第1の除塵フィルタ27a、及び第2の除塵フィルタ27bにおける塵埃の付着量の平準化を図り、フィルタの目詰まりによる風量低下をさらに防止することができる。   When the first dust filter 27a and the second dust filter 27b are rotated by driving the rotary motor 143, the amount of dust adhering to the first dust filter 27a and the second dust filter 27b is shifted depending on the location of the first dust filter 27a. It is possible to prevent a non-constant state, that is, a state where a large amount of dust adheres to the vicinity of the partition wall 26 where the suction force of the electric blower 2 is strong. Further, it is possible to equalize the amount of dust adhering to the first dust removing filter 27a and the second dust removing filter 27b, and to further prevent a decrease in air volume due to clogging of the filter.

以上の、本実施の形態3の電気掃除機を用いて風量維持性能の評価試験を行った。実験方法は同様に、家庭塵埃を篩を用いて綿ゴミと細塵に分離し、綿ゴミを4g、細塵を3g混合し、1回につき7g吸引させて風量の変化を調べた。その結果を図15に示す。   The evaluation test of the air volume maintenance performance was performed using the electric vacuum cleaner of the third embodiment. Similarly, in the experiment method, household dust was separated into cotton dust and fine dust using a sieve, 4 g of cotton dust and 3 g of fine dust were mixed, and 7 g was sucked at a time to examine the change in the air volume. The result is shown in FIG.

図15に示すように、本実施の形態3では、実施の形態2よりも風量維持性能に優れていることがわかる。   As shown in FIG. 15, it can be seen that the third embodiment is superior to the second embodiment in air volume maintenance performance.

このように本実施の形態3の電気掃除機は、吸込み仕事率を高位に確保し、塵埃を吸引しても吸込風量が低下しにくく、また、除塵フィルタへの塵埃の付着量の平準化が図れ、長期間メンテナンス不要の電気掃除機を提供することができる。   As described above, the vacuum cleaner of the third embodiment ensures a high suction work rate, the suction air volume is not easily lowered even when dust is sucked, and the amount of dust adhering to the dust filter is leveled. A vacuum cleaner that does not require maintenance for a long time can be provided.

(実施の形態4)
次に本発明の実施の形態4について説明する。以下では、実施の形態1〜3の構成、動作との相違点を中心に述べ、同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 4)
Next, a fourth embodiment of the present invention will be described. In the following, differences from the configurations and operations of the first to third embodiments will be mainly described, and the same components are denoted by the same reference numerals, and description of the configurations and operations will be omitted.

図16、図17に、本実施の形態4の電気掃除機の集塵ケース5、およびその要部断面図を示す。図16において、第1の塵埃除去手段161は集塵ケース5の上部または下部の少なくとも1箇所で固定されている。   16 and 17 show a dust collection case 5 of the electric vacuum cleaner according to the fourth embodiment and a cross-sectional view of a main part thereof. In FIG. 16, the first dust removing means 161 is fixed at at least one place on the upper or lower portion of the dust collecting case 5.

ここで、第1の塵埃除去手段161は図17に示すように両端部を尖らせたヘラ状であり、第1の除塵フィルタ27aの内周に押圧されて接している。   Here, the first dust removing means 161 has a spatula shape with both ends sharpened as shown in FIG. 17, and is pressed against and contacted with the inner periphery of the first dust removing filter 27a.

このとき、実施の形態3で説明したように、回転モータ143、駆動歯車142により、第2の除塵フィルタ27b上の駆動歯車141を回転させ、第2の除塵フィルタ27bと第1の除塵フィルタ27aとを一体に両方とも回転させると、第1の塵埃除去手段161は、第1の除塵フィルタ27aの内面を押圧しながらすべる。そのため、第1の除塵フィルタ27aの内面をクリーニングし、第1の除塵フィルタ27aの内面に付着したりからまっている綿ゴミやリントなどの塵埃を除去することができ、第1の除塵フィルタ27aの通気性を確保し、風量低下を防ぐことができ、また第1除塵フィルタ27aを取り外して清掃する手間が省け長期間メンテナンス不要の掃除機とすることができる。   At this time, as described in the third embodiment, the drive gear 141 on the second dust filter 27b is rotated by the rotation motor 143 and the drive gear 142, and the second dust filter 27b and the first dust filter 27a are rotated. Are rotated together, the first dust removing means 161 slides while pressing the inner surface of the first dust removing filter 27a. Therefore, the inner surface of the first dust removing filter 27a can be cleaned to remove dust such as cotton dust and lint stuck to the inner surface of the first dust removing filter 27a, and the first dust removing filter 27a. Therefore, it is possible to prevent a decrease in the air volume, and to eliminate the trouble of removing and cleaning the first dust filter 27a, thereby providing a cleaner that does not require maintenance for a long time.

また、本実施の形態4では、第1の除塵フィルタ27aが1周5秒で回転するように設定し、図示していない制御手段により、電動送風機21の停止直後に5秒間モータ143の電源スイッチが入り、第2の除塵フィルタ27bと第1の除塵フィルタ27aとを一体に両方とも回転させるものとした。   Further, in the fourth embodiment, the first dust filter 27a is set to rotate in one revolution of 5 seconds, and a power switch of the motor 143 for 5 seconds immediately after the electric blower 21 is stopped by a control means (not shown). And the second dust filter 27b and the first dust filter 27a are both rotated together.

なお、ここでは、第1の塵埃除去手段161を1つだけとしたが、これを複数にすればなお効果がある。   Here, only one first dust removing means 161 is provided, but if there are a plurality of the first dust removing means 161, there is still an effect.

また、ここでは、第1の塵埃除去手段161の形状をヘラ状としたが、付着物の種類によりブラシ状、起毛状などに形状を変えれば形状特有の効果が得られる。   In addition, here, the shape of the first dust removing means 161 is a spatula shape, but if the shape is changed to a brush shape or a raised shape depending on the type of deposit, an effect peculiar to the shape can be obtained.

さらに、ここでは図16(a)に示すように、第1の塵埃除去手段161として集塵ケース5の上部に棒状のものを垂直方向に取り付けたが、図18に示すように、第1の除塵フィルタ27aの内周を押圧しながら角度を持たせて螺旋状に取り付けるようにすれば、第1の除塵フィルタ27aを回転させたときにせん断効果が増大し、からまった髪の毛や糸くずなどを切断しながらクリーニングでき、さらに効果が上がるものとなる。   Further, here, as shown in FIG. 16 (a), a rod-like object is attached vertically to the upper portion of the dust collecting case 5 as the first dust removing means 161. However, as shown in FIG. When the first dust removal filter 27a is rotated in a spiral shape while pressing the inner periphery of the dust removal filter 27a, the shear effect increases when the first dust removal filter 27a is rotated, and tangled hair, lint, etc. It is possible to clean while cutting, further improving the effect.

(実施の形態5)
次に本発明の実施の形態5について説明する。以下では、実施の形態1〜4の構成、動作との相違点を中心に述べ、同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 5)
Next, a fifth embodiment of the present invention will be described. In the following, differences from the configurations and operations of the first to fourth embodiments will be mainly described, and the same components are denoted by the same reference numerals, and description of the configurations and operations will be omitted.

図19に実施の形態5の電気掃除機の断面図を示す。   FIG. 19 shows a cross-sectional view of the electric vacuum cleaner according to the fifth embodiment.

図19(a)は実施の形態5の電気掃除機の集塵ケース5の縦断面図である。図19(a)において、第2の塵埃除去手段191は第2の除塵フィルタ27bの外側に設けたものである。また、図20にその要部の拡大図を示すように、第2の塵埃除去手段191には、金属箔を曲げてバネとした、たたき部201が取り付けられている。   FIG. 19A is a longitudinal sectional view of the dust collecting case 5 of the electric vacuum cleaner according to the fifth embodiment. In FIG. 19A, the second dust removing means 191 is provided outside the second dust removing filter 27b. Further, as shown in an enlarged view of the main part in FIG. 20, the second dust removing means 191 is provided with a hitting portion 201 which is a spring made by bending a metal foil.

駆動歯車141は第2の除塵フィルタ27bに接続され、第1の除塵フィルタ27aは、第2の除塵フィルタ27bと連動する様に取り付けられており、回転モータ143、駆動歯車142により駆動歯車141を回転させることで、第1の除塵フィルタ27a、第2の除塵フィルタ27bを連動して回転させる。   The drive gear 141 is connected to the second dust filter 27b, and the first dust filter 27a is attached so as to be linked to the second dust filter 27b. The drive gear 141 is driven by the rotary motor 143 and the drive gear 142. By rotating, the first dust filter 27a and the second dust filter 27b are rotated in conjunction with each other.

図19(b)、図20に示すように、第1の除塵フィルタ27a、第2の除塵フィルタ27bが回転すれば、第2の塵埃除去手段191に設けた、たたき部201が第2の除塵フィルタ2bに外側から打撃を加えることになり、第2の除塵フィルタ27bの略U字状をしているひだ折り形状のフィルタ41の内部に付着堆積した細塵51を落下させることになり、第2の除塵フィルタ27bをクリーニングすることができる。また、回転を持続させることにより第2の除塵フィルタ27bの全周をクリーニングすることができる。   As shown in FIG. 19B and FIG. 20, when the first dust removing filter 27a and the second dust removing filter 27b rotate, the hitting portion 201 provided in the second dust removing means 191 becomes the second dust removing filter. The filter 2b is hit from the outside, and the fine dust 51 deposited and deposited inside the substantially U-shaped fold-shaped filter 41 of the second dust removal filter 27b is dropped. 2 dust filter 27b can be cleaned. Further, the entire circumference of the second dust removing filter 27b can be cleaned by maintaining the rotation.

また、ここでは、第2の除塵フィルタ27bが1周5秒で回転するように設定し、図示していない制御手段により、電動送風機21の停止直後に5秒間モータ143の電源スイッチが入り、第2の除塵フィルタ27bと第1の除塵フィルタ27aとを連動させて両方とも回転させるものとした。   Also, here, the second dust filter 27b is set so as to rotate in one round 5 seconds, and the power switch of the motor 143 is turned on for 5 seconds immediately after the electric blower 21 is stopped by the control means (not shown). The two dust removing filters 27b and the first dust removing filter 27a are interlocked to rotate both.

従って、電動送風機21が停止したあと、5秒間第2の除塵フィルタ27bのクリーニングを行うことができ、第2の除塵フィルタ27bの全周囲に付着した塵埃を落下させることができる。   Therefore, after the electric blower 21 stops, the second dust removal filter 27b can be cleaned for 5 seconds, and the dust attached to the entire periphery of the second dust removal filter 27b can be dropped.

本実施の形態5でも、実施の形態1と同様の風量維持性能の評価試験を行った。その結果は図21に示すように、本実施の形態5では、実施の形態2よりも風量維持性能に優れていることがわかる。   In the fifth embodiment, the same air volume maintenance performance evaluation test as that in the first embodiment was performed. As shown in FIG. 21, the results show that the fifth embodiment is superior in air volume maintenance performance to the second embodiment.

このように、第1の除塵フィルタ27a、第2の除塵フィルタ27bを回転させることにより、第2の塵埃除去手段191を使って第2の集塵フィルタ27bに付着した塵埃を除去しクリーニングする。そのため、さらに風量低下を防止することができ、また第2除塵フィルタ27bを取り外して清掃する手間が省け長期間メンテナンス不要の電気掃除機とすることができる。   In this way, by rotating the first dust removing filter 27a and the second dust removing filter 27b, the dust attached to the second dust collecting filter 27b is removed and cleaned by using the second dust removing means 191. For this reason, it is possible to further prevent a reduction in the air volume, and to eliminate the trouble of removing and cleaning the second dust removing filter 27b, thereby making it possible to provide a vacuum cleaner that does not require maintenance for a long time.

なお、ここでは、第2の塵埃除去手段として、たたき部201を金属箔を曲げてバネとしたものを用いたが、板形状のものやゴムなどの弾性体などでも構わない。   Here, as the second dust removing means, the hitting portion 201 is formed by bending a metal foil into a spring, but a plate-shaped member or an elastic body such as rubber may be used.

(実施の形態6)
次に本発明の実施の形態6について説明する。以下では、実施の形態1〜5の構成、動作との相違点を中心に述べ、同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 6)
Next, a sixth embodiment of the present invention will be described. In the following, differences from the configurations and operations of the first to fifth embodiments will be mainly described, and the same components are denoted by the same reference numerals, and description of the configurations and operations will be omitted.

図22に、本発明の実施の形態6における電気掃除機の集塵ケース5の斜視図を示す。   In FIG. 22, the perspective view of the dust collection case 5 of the vacuum cleaner in Embodiment 6 of this invention is shown.

図22において、第3の塵埃除去手段221は集塵ケース5のケース上部22aに固定され、ケース上部22aはケース中央部22bと気密性を保持しながら回転するように構成している。   In FIG. 22, the third dust removing means 221 is fixed to the case upper portion 22a of the dust collecting case 5, and the case upper portion 22a is configured to rotate while maintaining airtightness with the case central portion 22b.

ここで、第3の塵埃除去手段221は図23に示すように両端部を尖らせたヘラ状であり、第1の除塵フィルタ27aの内周に押圧されて接している。   Here, as shown in FIG. 23, the third dust removing means 221 has a spatula shape with both ends sharpened, and is pressed against and in contact with the inner periphery of the first dust removing filter 27a.

このときケース上部22aを回転させると、第3の塵埃除去手段221は第1の除塵フィルタ27aの内面を押圧しながらすべるため、第1の除塵フィルタ27aの内面をクリーニングし、第1の除塵フィルタ27aの内面に付着し、からまった綿ゴミやリントなどの塵埃を除去することができ、第1の除塵フィルタ27aの通気性を確保し風量低下を防ぎ、第1除塵フィルタ27aを取り外して清掃する手間が省け長期間メンテナンス不要の掃除機とすることができる。   When the case upper part 22a is rotated at this time, the third dust removing means 221 slides while pressing the inner surface of the first dust removing filter 27a. Therefore, the inner surface of the first dust removing filter 27a is cleaned and the first dust removing filter is removed. It is possible to remove dust such as tangled cotton dust and lint that adheres to the inner surface of the 27a, ensures the air permeability of the first dust removing filter 27a, prevents a decrease in the air volume, and removes the first dust removing filter 27a for cleaning. Therefore, it is possible to provide a vacuum cleaner that does not require maintenance for a long time.

なお、ここでは、1本の第3の塵埃除去手段221を示したが、複数にすればなお効果がある。   In addition, although the one 3rd dust removal means 221 was shown here, it will still be effective if it makes more than one.

また、ここでは第3の塵埃除去手段221の形状をヘラ状としたが、付着物の種類によりブラシ状、起毛状などに形状を変えれば形状特有の効果が得られる。   Here, the shape of the third dust removing means 221 is a spatula shape, but if the shape is changed to a brush shape or a raised shape depending on the type of deposit, an effect specific to the shape can be obtained.

さらには、ここでは第3の塵埃除去手段221を垂直方向に取り付けたが、図24に示すように角度を持たせて螺旋状に取り付けるようにすれば、第3の塵埃除去手段221を回転させたときにせん断効果が増大し、からまった髪の毛や糸くずなどを切断しながらクリーニングでき、さらに効果が上がるものとなる。   Furthermore, although the third dust removing means 221 is attached in the vertical direction here, if the third dust removing means 221 is attached in a spiral shape with an angle as shown in FIG. 24, the third dust removing means 221 is rotated. The shearing effect increases, and the hair can be cleaned while cutting tangled hair or lint, and the effect is further improved.

尚、このケース上部22aに固定した第3の塵埃除去手段221を回転させる手段としては、例えば構成をシンプルにできる手動で任意の方向に回転させる方法でも良いし、或いは、図示していない回転駆動手段と制御手段とを有し、電動送風機21の作動または停止のタイミングと連動して、第3の塵埃除去手段221を回転させる様にしても良い。   In addition, as a means to rotate the 3rd dust removal means 221 fixed to this case upper part 22a, the method of rotating manually in arbitrary directions which can simplify a structure may be sufficient, for example, or the rotational drive which is not illustrated The third dust removing unit 221 may be rotated in conjunction with the operation or stop timing of the electric blower 21.

(実施の形態7)
次に本発明の実施の形態7について説明する。以下では、実施の形態1〜6の構成、動作との相違点を中心に述べ、同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 7)
Next, a seventh embodiment of the present invention will be described. In the following, the differences from the configurations and operations of the first to sixth embodiments will be mainly described, and the same elements will be denoted by the same reference numerals, and description of the configurations and operations will be omitted.

図25に本発明の実施の形態7における電気掃除機の集塵ケース5の斜視図を、図26に同電気掃除機の第4の塵埃除去手段(円筒カゴ251)の要部断面図を示す。   FIG. 25 is a perspective view of the dust collecting case 5 of the vacuum cleaner according to Embodiment 7 of the present invention, and FIG. 26 is a cross-sectional view of the main part of the fourth dust removing means (cylindrical basket 251) of the vacuum cleaner. .

図25は、第2の除塵フィルタ27bの外側の空間部33に、第4の塵埃除去手段である円筒カゴ251を設けたものである。本実施の形態7においては、図25に示すように、円筒カゴ251は、上下の円周状回転歯車252を複数のつなぎ部253でつなぎ、このつなぎ部253に打撃部254を取り付けて構成されている。この打撃部254は、図26に示すように金属箔を曲げてバネとしたもので、つなぎ部253に取り付けられている。   In FIG. 25, a cylindrical basket 251 serving as a fourth dust removing means is provided in the space 33 outside the second dust filter 27b. In the seventh embodiment, as shown in FIG. 25, the cylindrical cage 251 is configured by connecting the upper and lower circumferential rotating gears 252 with a plurality of connecting portions 253 and attaching a striking portion 254 to the connecting portions 253. ing. As shown in FIG. 26, the striking portion 254 is a spring formed by bending a metal foil, and is attached to the connecting portion 253.

そして、円周状回転歯車252をモータ255に備えた駆動歯車256で回転させることで、円筒カゴ251を回転させ、打撃部254で第2の除塵フィルタ27bの外周を加振するかまたは打撃を加えるものである。   Then, by rotating the circumferential rotating gear 252 with the driving gear 256 provided in the motor 255, the cylindrical cage 251 is rotated, and the outer periphery of the second dust removing filter 27b is vibrated or hit by the hitting portion 254. It is something to add.

第4の塵埃除去手段である円筒カゴ251が回転すれば、打撃部254が第2の除塵フィルタ27bの外周を加振するかまたは打撃を加え、第2の除塵フィルタ27bのひだの内部、特にくぼみ部42に付着堆積した細塵51を落下させることになり、第2の除塵フィルタ27bをクリーニングすることができる。また、回転を持続させることにより第2の除塵フィルタ27bの全周をクリーニングすることができる。   If the cylindrical cage 251 that is the fourth dust removing means rotates, the striking part 254 vibrates or applies an impact to the outer periphery of the second dust removing filter 27b, and particularly inside the folds of the second dust removing filter 27b, The fine dust 51 adhering and accumulating in the hollow portion 42 is dropped, and the second dust removing filter 27b can be cleaned. Further, the entire circumference of the second dust removing filter 27b can be cleaned by maintaining the rotation.

また、ここでは、円筒カゴ251が1周5秒で回転するように設定し、図示していない制御手段により、電動送風機21の停止直後に5秒間モータ255の電源スイッチが入り、第4の除塵手段である回転カゴ251が一回転するものとし、第2の除塵フィルタ27bの全周をクリーニングすることとした。   Also, here, the cylindrical cage 251 is set to rotate in one round 5 seconds, and the power switch of the motor 255 is turned on for 5 seconds immediately after the electric blower 21 is stopped by the control means (not shown), and the fourth dust removal It is assumed that the rotating basket 251 serving as means rotates once, and the entire circumference of the second dust removing filter 27b is cleaned.

本実施の形態7でも、他の実施の形態と同様に風量維持性能の評価試験を行った。   In the seventh embodiment, an air volume maintenance performance evaluation test was performed as in the other embodiments.

その結果は図27に示すように、本実施の形態7では、実施の形態2よりも風量維持性能に優れていることがわかる。   As shown in FIG. 27, the result shows that the seventh embodiment is superior to the second embodiment in the air volume maintenance performance.

このように、第4の塵埃除去手段である円筒カゴ251を回転させることにより、第2の集塵フィルタ27bに付着した塵埃を除去しクリーニングするため、さらに風量低下を防止することができ、また第2除塵フィルタ27bを取り外して清掃する手間が省け長期間メンテナンス不要の電気掃除機とすることができる。   In this way, by rotating the cylindrical cage 251 as the fourth dust removing means, the dust attached to the second dust collecting filter 27b is removed and cleaned, so that it is possible to prevent a further decrease in the air volume. It is possible to provide a vacuum cleaner that does not require maintenance for a long period of time without the need to remove and clean the second dust filter 27b.

なお、ここでは、打撃部254として金属箔を曲げてバネとしたものを用いたが、板形状のものや、ゴムなどの弾性体などでも構わない。   In this case, the hitting portion 254 is made of a metal foil bent as a spring, but it may be a plate or an elastic body such as rubber.

また、ここでは、図示していない制御手段を用いて第4の塵埃除去手段である円筒カゴ251のみを回転させるようにしたが、同様にこの制御手段を用いて実施の形態6の第3の塵埃除去手段221を回転させても構わないし、これらを同時に回転或いは時間をずらして回転させてもかまわない。   Here, only the cylindrical cage 251 which is the fourth dust removing means is rotated using the control means (not shown). Similarly, the third means of the sixth embodiment is used using this control means. The dust removing means 221 may be rotated, or these may be rotated at the same time or at different times.

(実施の形態8)
次に本発明の実施の形態8について説明する。以下では、実施の形態1〜7の構成、動作との相違点を中心に述べ、同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 8)
Next, an eighth embodiment of the present invention will be described. In the following, the differences from the configurations and operations of the first to seventh embodiments will be mainly described, and the same components will be denoted by the same reference numerals, and description of the configurations and operations will be omitted.

図28に、本発明の実施の形態8における電気掃除機の集塵ケース5の斜視図を、図29(a)に塵埃がたまった状態を横から見た側断面図、図29(b)に開閉蓋31を開けた状態での側断面図を示す。   FIG. 28 is a perspective view of the dust collecting case 5 of the electric vacuum cleaner according to the eighth embodiment of the present invention. FIG. 29A is a side sectional view of the dust collected from the side, and FIG. Fig. 2 shows a side sectional view in a state where the opening / closing lid 31 is opened.

図28に示すように、本実施の形態8では、第3の除塵フィルタ28を上下の開いた略円錐台形状とし、この円錐台の上部径は第1の集塵フィルタ27aの下端径と一致させて当接している。また、この円錐台の下部径は塵埃収容部24底部の内径よりも小さくし、この円錐台の下部を塵埃収容部24底部に隙間なく当接させたものである。その他は本発明の実施の形態1と同様である。またこのとき、第3の除塵フィルタ28は実施の形態1と同様に、通気孔径が250ミクロンの金属メッシュで作製した粗塵フィルタである。   As shown in FIG. 28, in the eighth embodiment, the third dust removal filter 28 has a substantially truncated cone shape that is open up and down, and the upper diameter of the truncated cone matches the lower end diameter of the first dust collection filter 27a. Are in contact. Further, the lower diameter of the truncated cone is made smaller than the inner diameter of the bottom of the dust container 24, and the lower part of the truncated cone is brought into contact with the bottom of the dust container 24 without a gap. The rest is the same as in the first embodiment of the present invention. At this time, the third dust filter 28 is a coarse dust filter made of a metal mesh having a vent hole diameter of 250 microns, as in the first embodiment.

第3の除塵フィルタ28を上下の開いた略円錐台形状としても空気の流れは実施の形態1と同様であり、細塵51は第2の除塵フィルタで濾し取られ、粗塵52は塵埃収容部24に捕捉され堆積する。   Even if the third dust removal filter 28 has a substantially truncated cone shape with the top and bottom open, the air flow is the same as in the first embodiment, the fine dust 51 is filtered by the second dust removal filter, and the coarse dust 52 is stored in the dust. It is captured and deposited by the part 24.

ここで、実施の形態7に示す第4の塵埃除去手段などを用い、第2の除塵フィルタから剥離し落下した細塵51は、図29(a)に示すように、第3の除塵フィルタ28の外側の円錐母線で形成される斜面をつたって、確実に塵埃収容部24の底面に落下する。このため、落下した細塵51と第2の除塵フィルタ27bとの距離を離すことができ、落下した細塵51に及ぼす吸引作用が減少し、細塵51の第2の除塵フィルタ27bへの再付着を防止でき、フィルタ目詰まりによる風量低下を防止することができる。   Here, the fine dust 51 peeled off from the second dust removing filter using the fourth dust removing means shown in the seventh embodiment or the like is removed from the third dust removing filter 28 as shown in FIG. It is surely dropped to the bottom surface of the dust container 24 through the slope formed by the outer cone bus. For this reason, the distance between the fine dust 51 that has fallen and the second dust removal filter 27b can be increased, the suction action on the fine dust 51 that has fallen is reduced, and the fine dust 51 is reapplied to the second dust removal filter 27b. Adhesion can be prevented, and a reduction in air volume due to filter clogging can be prevented.

そしてさらに、第3の除塵フィルタ28を上記の様な円錐台形状とすることにより、第3の除塵フィルタ28の内側に粗塵52が詰まってきても、上部空間より下部空間の方が広いため、粗塵52の広がり等による第3の除塵フィルタ28との圧接が起こり難い。また、図29(b)に示すように、塵埃収容部24の底面に設けたヒンジ32を介して開閉蓋31を開けば、重力の作用により塵埃は容易に第3の除塵フィルタ28から離脱除去するため、塵埃を引っ掛かり無く排出でき、ゴミ捨て性能に優れた電気掃除機とすることができる。   Furthermore, since the third dust removal filter 28 has a truncated cone shape as described above, even if the coarse dust 52 is clogged inside the third dust removal filter 28, the lower space is wider than the upper space. Further, pressure contact with the third dust removing filter 28 due to the spread of the coarse dust 52 or the like hardly occurs. In addition, as shown in FIG. 29 (b), if the opening / closing lid 31 is opened via a hinge 32 provided on the bottom surface of the dust container 24, the dust is easily removed from the third dust filter 28 by the action of gravity. Therefore, dust can be discharged without being caught, and a vacuum cleaner with excellent dust disposal performance can be obtained.

(実施の形態9)
次に本発明の実施の形態9について説明する。以下では、実施の形態1〜8の構成、動作との相違点を中心に述べ、同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 9)
Next, a ninth embodiment of the present invention will be described. In the following, differences from the configurations and operations of the first to eighth embodiments will be mainly described, and the same components are denoted by the same reference numerals, and description of the configurations and operations will be omitted.

図30に、本発明の実施の形態9における電気掃除機の集塵ケース5の斜視図を、図31(a)に塵埃がたまった状態を横から見た側断面図、図31(b)に開閉蓋31を開けた状態での側断面図を示す。   FIG. 30 is a perspective view of the dust collecting case 5 of the electric vacuum cleaner according to Embodiment 9 of the present invention. FIG. 31A is a side cross-sectional view of the state where dust is accumulated, and FIG. 31B. Fig. 2 shows a side sectional view in a state where the opening / closing lid 31 is opened.

図30に示すように、本実施の形態9では、第1の除塵フィルタ27aの形状を、下部径を上部径より大きくした円錐台形状としている。   As shown in FIG. 30, in the ninth embodiment, the shape of the first dust removing filter 27a is a truncated cone shape in which the lower diameter is larger than the upper diameter.

第1の除塵フィルタ27aの形状を以上のような円錐台形状とすることにより、図31(a)に示すように、塵埃収容部24で収容できる塵埃量以上の塵埃を吸引してしまい、第1の除塵フィルタ27a内に粗塵52が詰まってきても、上部空間より下部空間の方が広いため、粗塵52の広がり等による第1の除塵フィルタ27aとの圧接が起こり難い。また、図31(b)に示すように、塵埃収容部24の底面に設けたヒンジ32を介して開閉蓋31を開けば、重力の作用により塵埃は容易に第1の除塵フィルタ27aから離脱除去するため、塵埃を引っ掛かり無く排出でき、ゴミ捨て性能に優れた電気掃除機とすることができる。   By making the shape of the first dust removal filter 27a into the truncated cone shape as described above, as shown in FIG. 31 (a), dust larger than the amount of dust that can be accommodated in the dust accommodating portion 24 is sucked, and Even if the coarse dust 52 is clogged in the single dust removal filter 27a, the lower space is wider than the upper space, and therefore the pressure contact with the first dust removal filter 27a due to the spread of the coarse dust 52 or the like hardly occurs. Further, as shown in FIG. 31 (b), if the opening / closing lid 31 is opened via a hinge 32 provided on the bottom surface of the dust container 24, dust is easily removed from the first dust filter 27a by the action of gravity. Therefore, dust can be discharged without being caught, and a vacuum cleaner with excellent dust disposal performance can be obtained.

(実施の形態10)
次に本発明の実施の形態10について説明する。以下では、実施の形態1〜9の構成、動作との相違点を中心に述べ、同一要素については同一符号を付してその構成、動作の説明を省略する。
(Embodiment 10)
Next, an embodiment 10 of the invention will be described. In the following, differences from the configurations and operations of the first to ninth embodiments will be mainly described, and the same components are denoted by the same reference numerals, and description of the configurations and operations will be omitted.

図32、図33に本実施の形態10の構成を示す。第3の除塵フィルタ28の一部には開口部321が設けられている。また、この開口部321の下方に、第2の塵埃除去手段191により除去された塵埃を収容する塵埃室322が設けられている。塵埃室322は塵埃収容部24内で区切られて形成され、第2の塵埃除去手段191により除去された塵埃はこの区切られた塵埃室322に収容される。   32 and 33 show the configuration of the tenth embodiment. An opening 321 is provided in a part of the third dust filter 28. Further, a dust chamber 322 for storing the dust removed by the second dust removing means 191 is provided below the opening 321. The dust chamber 322 is formed by being partitioned in the dust container 24, and the dust removed by the second dust removing means 191 is stored in the partitioned dust chamber 322.

また、第2の塵埃除去手段191によって除去された塵埃が開口部321から塵埃室322内に確実に収容するように、図32、図33に示す様に、第2の塵埃除去手段191の直下に開口部321とこの開口部321と連通させた塵埃室322とを配置させている。また、開口部321と塵埃室322の入り口の形状を一致させることにより、開口部321に落ちてきた塵埃を確実に塵埃室322に収容することができる。   Further, as shown in FIGS. 32 and 33, the dust removed by the second dust removing means 191 is surely stored in the dust chamber 322 through the opening 321 as shown in FIGS. An opening portion 321 and a dust chamber 322 communicated with the opening portion 321 are disposed in the space. Further, by matching the shapes of the entrances of the opening 321 and the dust chamber 322, the dust that has fallen into the opening 321 can be reliably accommodated in the dust chamber 322.

さらに塵埃室322を塵埃収容部24内に設けることにより、塵埃収容部24に収容されたゴミをゴミ箱に捨てる場合に、塵埃室322の塵埃も同時に捨てることができる。   Further, by providing the dust chamber 322 in the dust container 24, when the dust stored in the dust container 24 is thrown into the trash box, the dust in the dust chamber 322 can be discarded at the same time.

また、塵埃室322に通風口323を設け、この通風口323を塞ぐ第4の除塵フィルタ324を設けている。この第4の除塵フィルタ324は第3の除塵フィルタ28と同様に、通気孔径が250ミクロンの金属メッシュの粗塵フィルタで構成されている。   Further, a ventilation port 323 is provided in the dust chamber 322, and a fourth dust removal filter 324 that closes the ventilation port 323 is provided. Similar to the third dust filter 28, the fourth dust filter 324 is a metal dust coarse filter having a vent hole diameter of 250 microns.

さらに、この第4の除塵フィルタ324の吸引風路中の配置は、第3の除塵フィルタ28の場合と同様に、吸引口6からの空気を、第1の除塵フィルタ27aの円筒中空部、塵埃収容部24を経て、塵埃室の通風口323を介して第2の除塵フィルタ27bの下端部に流れる第2の風路である副風路29bの途中に設けている。   Further, the fourth dust removal filter 324 is arranged in the suction air passage in the same manner as in the third dust removal filter 28, and the air from the suction port 6 is exchanged with the cylindrical hollow portion of the first dust removal filter 27a and the dust. It is provided in the middle of the auxiliary air passage 29b that is the second air passage that flows to the lower end portion of the second dust removing filter 27b through the housing portion 24 and the air outlet 323 of the dust chamber.

次に、本実施の形態10の動作について説明する。   Next, the operation of the tenth embodiment will be described.

第2の塵埃除去手段191により除去された細塵51は、第3の除塵フィルタ28に設けられた開口部321に落下することにより塵埃室322に収容される。細塵51を収納する塵埃室322を塵埃収容部24内に設けることにより、清掃時の塵埃の再巻き上げ量をより低減することができ、第1の風路である主風路29aと第2の風路である副風路29bを通過する風量低下を防止することができる。   The fine dust 51 removed by the second dust removing means 191 is stored in the dust chamber 322 by dropping into the opening 321 provided in the third dust removing filter 28. By providing the dust chamber 322 for storing the fine dust 51 in the dust accommodating portion 24, the amount of dust rewinding during cleaning can be further reduced, and the main air passage 29a and the second air passage which are the first air passages can be reduced. It is possible to prevent a decrease in the amount of air passing through the auxiliary air passage 29b which is the air passage.

また、塵埃室に通風口323を設け、その通風口323に金属メッシュの第4の除塵フィルタ324を配置することにより、第2の風路である副風路29bを確保することができる。よって、実施の形態2で説明したように、塵埃を吸引すると、粗塵51は塵埃収容部24に捕捉されるため、第1除塵フィルタ27aおよび第2の除塵27bの周囲にわたって風路が確保され、風量低下を防ぐことができる。   Further, by providing the ventilation port 323 in the dust chamber and disposing the fourth dust filter 324 made of metal mesh in the ventilation port 323, the auxiliary air passage 29b that is the second air passage can be secured. Therefore, as described in the second embodiment, when dust is sucked, the coarse dust 51 is captured by the dust container 24, so that an air path is secured around the first dust filter 27a and the second dust filter 27b. , Can prevent the air volume drop.

また、除去された細塵51を区切られた塵埃室322に粗塵52と分離して収納することにより、清掃時の細塵51の巻き上げによる第2の除塵フィルタ27bへの再付着を防止することができ、第1の風路である主風路29aと第2の風路である副風路29bを通過する風量低下をより効果的に防止できる。   Further, the removed fine dust 51 is stored separately from the coarse dust 52 in the partitioned dust chamber 322, thereby preventing the fine dust 51 from being reattached to the second dust filter 27b due to the fine dust 51 being rolled up during cleaning. Therefore, it is possible to more effectively prevent a decrease in the amount of air passing through the main air passage 29a that is the first air passage and the auxiliary air passage 29b that is the second air passage.

以上のように、本発明にかかる電気掃除機は、高い吸込み仕事率を確保しながら、かつ塵埃を吸引しても吸込力が低下しにくい電気掃除機を提供することができるので、除塵フィルタの清掃や塵埃の排出などのメンテナンス作業を大きく軽減することができ、家庭用電気掃除機だけでなく、業務用電気掃除機などさまざま種類の掃除機に使用することが可能となる。   As described above, the vacuum cleaner according to the present invention can provide a vacuum cleaner in which the suction force is not easily reduced even if dust is sucked while securing a high suction work rate.
