Description

本発明は、電気掃除機のサイクロン集塵装置に関するものである。   The present invention relates to a cyclone dust collecting device for a vacuum cleaner.

近年、吸引風の気流に旋回成分を持たせ、遠心力により気流から塵埃を分離除去するタイプの電気掃除機、いわゆるサイクロン型の電気掃除機が注目を浴びている。この種の電気掃除機において、集塵ケースは、旋回気流を発生させる旋回発生室と、この旋回発生室とは連通させて区画分離した集塵室を設け、集塵ケースへ流入した含塵空気を、旋回室で旋回させた後、塵埃を別室となる集塵室へと移動させて塵埃を溜めるという構成のものがある(特許文献1、および特許文献2参照)。   2. Description of the Related Art In recent years, a so-called cyclone type vacuum cleaner that attracts attention is a type of vacuum cleaner that imparts a swirling component to the airflow of suction air and separates and removes dust from the airflow by centrifugal force. In this type of vacuum cleaner, the dust collection case is provided with a swirl generation chamber that generates a swirling air flow, and a dust collection chamber that is separated from the swirl generation chamber and communicated with the swirl generation chamber. Is configured to move dust to a dust collection chamber, which is a separate chamber, and collect the dust (see Patent Document 1 and Patent Document 2).

特表2003−517908号公報Special table 2003-517908 gazette 特開2003−112082号公報JP 2003-112082 A

特許文献1の構成は、含塵空気を旋回させる旋回発生室と、旋回発生室の内部に連通した導入部を有した集塵部を具備し、集塵部に対して連通した第1端と、旋回室の内部に対して連通した第2端とを有したエア戻りダクトを具備しており、集塵室の導入部との連通口とエア戻りダクトとの連通口を離間させるように配置し、かつ、このエア戻りダクトの旋回発生室に連通した第2端が、旋回発生室における旋回気流方向に対して鋭角に流入するように構成したものであり、この場合、旋回発生室から集塵室までの導入部、およびエア戻りダクトでの配管ロスが影響して、集塵室内に十分な負圧を生成できず、旋回発生室から集塵室への流速が減少し、スムーズな塵埃輸送ができない。また、集塵室への導入部の連通口と集塵室のエア戻りダクトの連通口とを離間させるため、かつ、エア戻りダクトから旋回発生室への連通を旋回発生室での旋回気流方向に鋭角に流入するようにするため、旋回発生室から導入部→集塵室→エア戻りダクト、そして最後に、旋回発生室へと戻る一連の経路が屈曲させた状態となってしまうため、流れにみだれが生じ流路圧損となり、これによっても塵埃を旋回発生室から集塵室へと空気移送させるには影響を及ぼしてしまう。この塵埃移送が確実に行えなければ、旋回室内に含塵空気が旋回し続けることとなるため、塵埃分離性が低下してしまう。   The configuration of Patent Document 1 includes a swirl generation chamber that swirls dust-containing air, and a dust collection unit that has an introduction portion that communicates with the inside of the swirl generation chamber, and a first end that communicates with the dust collection unit; The air return duct has a second end communicating with the inside of the swirl chamber, and is arranged so as to separate the communication port between the inlet of the dust collection chamber and the air return duct. In addition, the second end of the air return duct communicating with the swirl generation chamber is configured to flow at an acute angle with respect to the swirl airflow direction in the swirl generation chamber. Due to the pipe loss at the introduction part to the dust chamber and the air return duct, sufficient negative pressure cannot be generated in the dust collection chamber, the flow velocity from the swirl generation chamber to the dust collection chamber decreases, and smooth dust Cannot be transported. Also, in order to separate the communication port of the introduction part to the dust collection chamber and the communication port of the air return duct of the dust collection chamber, and the communication from the air return duct to the swirl generation chamber, the swirl air flow direction in the swirl generation chamber In order to flow at an acute angle, the flow from the swirl generation chamber to the introduction part → dust collection chamber → air return duct, and finally, a series of paths returning to the swirl generation chamber will be bent. As a result, sag occurs and flow path pressure loss occurs, which also affects the air transfer of dust from the swirl generation chamber to the dust collection chamber. If this dust transfer cannot be performed reliably, the dust-containing air will continue to swirl in the swirl chamber, and the dust separation performance will be reduced.

また、特許文献2の構成においてであるが、本構成は、含塵空気を旋回させる円筒形状の旋回室と、旋回室の接線方向に形成された吸気口と、旋回室の底面中央部分に設けられた排気口と、旋回室側面に隣接して設けられた集塵室と、旋回室の側面に吸気口と旋回軸方向に重複する位置に設けられた旋回室と集塵室とを連通させる連通穴とを備え、連通穴は、旋回上流側から集塵室に流入する流出口と、旋回室下流側に集塵室から旋回室に戻る流入口を設けたものであり、ここでは、吸気口の開口高さ、旋回室高さ、集塵室への連通穴(入口/出口)の開口高さがほぼ同一高さとしているため、吸気口から流入する気流と、集塵室から旋回室へと戻ってきた気流とが衝突するため、乱流が発生し、この衝突付近では排気口に向かう流れとなり、まだ旋回室を旋回する気流に乗っていた塵埃がそのまま排気口側へと流され、結果、充分な塵埃分離には至らないことになってしまう。また、吸気口、および、集塵室への流出口と流入口が同じ高さにあることで、旋回室から集塵室に進入する気流には水平成分が強く作用しているため、集塵室に入ってからの旋回気流はそのまま旋回室側への流入口へと向かうこととなり、この場合、特に微小な塵埃に対しては
、空気と分離して集塵室の底へと落ちることなく、そのまま流入口から気流に乗って旋回室側へと戻ってしまう。さらに集塵室内は、連通口付近では旋回室の円筒形状が食い込んだ凹形状となっているため、集塵室から旋回室側への流入口付近では、気流の旋回によって塵埃を空気から分離するのではなく、旋回室側へ気流を誘引する方向に作用するため、旋回室側に逆流する含塵空気の頻度が増加してしまい、そのため、塵埃分離性が低下してしまうことにつながる。
Moreover, although it is in the structure of patent document 2, this structure is provided in the cylindrical turning chamber which turns dust-containing air, the inlet port formed in the tangential direction of the turning chamber, and the bottom center part of the turning chamber. The exhaust port, the dust collection chamber provided adjacent to the side surface of the swirl chamber, and the swirl chamber and dust collection chamber provided on the side surface of the swirl chamber so as to overlap with the intake port in the swirl axis direction. The communication hole is provided with an outlet that flows into the dust collecting chamber from the swirling upstream side, and an inlet that returns from the dust collecting chamber to the swirling chamber on the downstream side of the swirling chamber. The opening height of the mouth, the height of the swirl chamber, and the opening height of the communication hole (inlet / outlet) to the dust collection chamber are almost the same height, so the airflow flowing from the intake port and the swirl chamber from the dust collection chamber Since the airflow returning to the air collides, turbulent flow occurs, and the flow toward the exhaust port is near the collision. Flowed into the still swirling chamber dust as it is the exhaust port side was riding the airflow to turning a result, it becomes that not lead to sufficient dust separation. In addition, since the air inlet and the outlet and inlet to the dust collection chamber are at the same height, the horizontal component acts strongly on the airflow entering the dust collection chamber from the swirl chamber. The swirling airflow after entering the chamber will go directly to the inlet to the swirling chamber, and in this case, especially for minute dust, it will not separate from the air and fall to the bottom of the dust collecting chamber. As it is, it gets on the airflow from the inlet and returns to the swirl chamber side. Furthermore, in the dust collection chamber, the cylindrical shape of the swirl chamber bites into the vicinity of the communication port, so that dust is separated from the air by swirling the airflow near the inlet from the dust collection chamber to the swirl chamber side. However, since it acts in the direction in which the airflow is attracted to the swirl chamber side, the frequency of the dust-containing air that flows back to the swirl chamber side increases, which leads to a decrease in dust separation.

本発明は、上記従来の課題を解決するもので、旋回室から別室となるように集塵室を構成しても、旋回気流によって旋回室側から集塵室側へと塵埃をスムーズに空気輸送し、塵埃分離性をさらに向上させたサイクロン集塵装置を具備する電気掃除機を提供する。   The present invention solves the above-described conventional problems, and even if the dust collecting chamber is configured to be a separate chamber from the swirling chamber, the dust is smoothly pneumatically transported from the swirling chamber side to the dust collecting chamber side by the swirling airflow. And a vacuum cleaner equipped with a cyclone dust collector with further improved dust separation.

上記目的を達成するために本発明の電気掃除機は、塵埃を吸引するための電動送風機、および吸引によって集塵した塵埃を溜める集塵ケースを配置し、前記集塵ケースには、塵埃を含む空気を旋回させる略円筒状の旋回室と、前記旋回室より塵埃を分離して溜める略円筒状の集塵室を設けたサイクロン掃除機において、前記旋回室と前記集塵室とは、互いの軸中心を平行にズラし、かつ、前記旋回室の下方と前記集塵室の上方とが相対して連通する構成とし、前記旋回室と前記集塵室とが相対する位置に、前記旋回室を旋回する含塵気流が、前記旋回室外周の内壁面に沿いながら前記集塵室へと流入する流入口と、前記集塵室で旋回する気流が、前記集塵室外周の内壁面を沿いながら前記旋回室へと再流入する流出口を設け、前記旋回室に含塵空気を取り入れる吸気口、前記旋回室の中心付近に配置気宇した塵埃分離した空気を排出する外周面に通気孔を設けた排気筒、および、前記集塵室への流入口/流出口の位置が、上から順に配置するように構成したもので、前記旋回室の底中心付近には、前記集塵室への流入口と流出口との開口縁とを連結させるように円弧状の区画壁を設け、前記旋回室の外周内壁面と前記区画壁との間で旋回経路を形成するように構成したものである。   To achieve the above object, an electric vacuum cleaner according to the present invention includes an electric blower for sucking dust and a dust collecting case for collecting dust collected by suction, and the dust collecting case includes dust. In a cyclone cleaner provided with a substantially cylindrical swirl chamber for swirling air and a substantially cylindrical dust collection chamber for separating and collecting dust from the swirl chamber, the swirl chamber and the dust collection chamber are The swirl chamber has a structure in which the center of the shaft is displaced in parallel and the lower portion of the swirl chamber and the upper portion of the dust collection chamber are in communication with each other, and the swirl chamber and the dust collection chamber are opposed to each other. The dust-containing airflow swirling in the dust collection chamber flows along the inner wall surface of the swirl chamber and the airflow swirling in the dust collection chamber along the inner wall surface of the dust collection chamber. However, an outlet is provided for re-inflow into the swirl chamber. An intake port for taking in air, an exhaust pipe provided with a vent on the outer peripheral surface for discharging the separated air arranged near the center of the swirl chamber, and the position of the inlet / outlet to the dust collection chamber An arcuate partition wall is formed near the bottom center of the swirl chamber so as to connect the opening edge of the inlet and the outlet to the dust collecting chamber. And a swirl path is formed between the outer peripheral inner wall surface of the swirl chamber and the partition wall.

このような発明によって、吸気口から流入した含塵空気は、旋回室内壁と排気筒、および区画壁とで区画された通路を旋回しながら、隣接させた集塵室へと気流をスムーズに誘引させることができるようになり、また、吸気口、排気筒の通気孔位置、集塵室との流入口/流出口とを上から順に高低差を付けた配置とし、旋回室の吸気口に対して集塵室の底位置が斜め下方となる構成としたことで、旋回室の吸気口から集塵室の底部分に向かって、旋回気流が斜め下方向に旋回しながら流れる気流となるため、集塵室内で塵埃は底部分まで確実に誘導され、集塵室上方に配置される集塵室から旋回室へ気流を戻す流出口までの間で、塵埃を分離させることができる。さらに、この吸気口/排気筒の通気孔位置/集塵室との流入・流出口との高低差により、旋回室内で、吸気口からの流入気流と、集塵室から旋回室へ戻る気流との衝突を、排気筒の通気孔よりも下方で発生させることになるため、衝突により発生する乱流の影響によって、旋回室から集塵室へ向かう気流を阻害することを抑えることができ、スムーズな塵埃移送性を確保することができるようになり、確実に旋回室とは別室にて塵埃を集塵できるようになるため、旋回室内で含塵空気が旋回しつづけることはないため、塵埃分離性をさらに向上させることができるようになる。   According to such an invention, the dust-containing air flowing in from the intake port smoothly draws the airflow to the adjacent dust collection chamber while swirling the passage defined by the swirl chamber wall, the exhaust pipe, and the partition wall. In addition, the air intake vent, the position of the vent of the exhaust pipe, and the inlet / outlet of the dust collection chamber are arranged with a level difference in order from the top. Since the bottom position of the dust collection chamber is diagonally downward, the swirling airflow turns obliquely downward from the swirl chamber inlet to the bottom of the dust collection chamber, Dust is reliably guided to the bottom in the dust collection chamber, and can be separated from the dust collection chamber disposed above the dust collection chamber to the outlet for returning the airflow to the swirl chamber. Furthermore, due to the difference in height between the inlet / exhaust vent position / inlet / outlet with the dust collection chamber, the inflow airflow from the intake port and the airflow returning from the dust collection chamber to the swirl chamber Is generated below the vent hole of the exhaust stack, so that it is possible to suppress the obstruction of the air flow from the swirl chamber to the dust collection chamber due to the influence of the turbulent flow generated by the collision. Dust transportability can be ensured, and dust can be collected in a separate chamber from the swirl chamber, so that the dust-containing air does not continue to swirl in the swirl chamber. The performance can be further improved.

本発明のサイクロン集塵装置は、旋回室から別室となるように集塵室を隣接して構成し、旋回気流を斜め下方向に流れるに構成したことで、旋回気流によって旋回室側から隣室への集塵室側へと塵埃をスムーズに空気輸送し、塵埃を旋回室とは別室にて確実に集塵させることで、塵埃と空気との分離性のさらなる向上を図ることができる。   In the cyclone dust collecting apparatus of the present invention, the dust collecting chamber is configured adjacent to the swirl chamber so as to be separated from the swirl chamber, and the swirling airflow is configured to flow obliquely downward. The dust can be smoothly pneumatically transported to the dust collection chamber side, and the dust can be reliably collected in a separate chamber from the swirl chamber, thereby further improving the separation between the dust and the air.

第1の発明は、塵埃を吸引するための電動送風機、および吸引によって集塵した塵埃を溜める集塵ケースを配置し、前記集塵ケースには、塵埃を含む空気を旋回させる略円筒状の旋回室と、前記旋回室より塵埃を分離して溜める略円筒状の集塵室を設けたサイクロン掃除機において、前記旋回室と前記集塵室とは、互いの軸中心を平行にズラし、かつ、前記旋回室の下方と前記集塵室の上方とが相対して連通する構成とし、前記旋回室と前記集塵室とが相対する位置に、前記旋回室を旋回する含塵気流が、前記旋回室外周の内壁面に沿いながら前記集塵室へと流入する流入口と、前記集塵室で旋回する気流が、前記集塵室外周の内壁面を沿いながら前記旋回室へと再流入する流出口を設け、前記旋回室に含塵空気を取り入れる吸気口、前記旋回室の中心付近に配置した塵埃分離した空気を排出する外周面に通気孔を設けた排気筒、および、前記集塵室への流入口/流出口の位置が、上から順に配置するように構成したもので、前記旋回室の底中心付近には、前記集塵室への流入口と流出口との開口縁とを連結させるように円弧状の区画壁を設け、前記旋回室の外周内壁面と前記区画壁との間で旋回経路を形成するように構成したものである。   1st invention arrange | positions the electric blower for attracting | sucking dust, and the dust collection case which accumulate | stores the dust collected by suction | inhalation, and the substantially cylindrical turning which makes the dust collection case swirl the air containing dust And a cyclone vacuum cleaner provided with a substantially cylindrical dust collection chamber for separating and collecting dust from the swirl chamber, the swirl chamber and the dust collection chamber are displaced in parallel with each other in the axial center, and The lower part of the swirl chamber communicates with the upper part of the dust collection chamber, and the dust-containing airflow swirling the swirl chamber is located at a position where the swirl chamber and the dust collection chamber face each other. An inlet that flows into the dust collection chamber along the inner wall surface of the swirl chamber and an airflow swirling in the dust collection chamber reflows into the swirl chamber along the inner wall surface of the dust collection chamber. An air outlet is provided, and an intake port for taking dust-containing air into the swirl chamber, An exhaust pipe provided with a vent on the outer peripheral surface for discharging dust-separated air arranged near the center of the chamber, and the position of the inlet / outlet to the dust collecting chamber are arranged in order from the top In the vicinity of the bottom center of the swirl chamber, an arc-shaped partition wall is provided so as to connect the opening edge of the inlet and the outlet to the dust collecting chamber, and the outer peripheral inner wall surface of the swirl chamber And a turning path between the partition wall and the partition wall.

これにより、吸気口から流入した含塵空気は、旋回室内壁と排気筒、および区画壁とで区画された通路を旋回しながら、隣接させた集塵室へと気流をスムーズに誘引させることができるようになり、また、吸気口、排気筒の通気孔位置、集塵室との流入口/流出口とを上から順に高低差を付けた配置とし、旋回室の吸気口に対して集塵室の底位置が斜め下方となる構成としたことで、旋回室の吸気口から集塵室の底部分に向かって、旋回気流が斜め下方向に旋回しながら流れる気流となるため、集塵室内で塵埃は底部分まで確実に誘導され、集塵室上方に配置される集塵室から旋回室へ気流を戻す流出口までの間で、塵埃を分離させることができる。   As a result, the dust-containing air flowing in from the intake port can smoothly draw the air flow to the adjacent dust collection chamber while swirling the passage partitioned by the swirl chamber wall, the exhaust pipe, and the partition wall. In addition, the air intake port, the vent hole position of the exhaust pipe, and the inlet / outlet of the dust collecting chamber are arranged with a level difference in order from the top, and the dust collecting is done with respect to the inlet of the swirl chamber. Since the bottom position of the chamber is obliquely downward, the swirling airflow turns into the dust collecting chamber from the inlet of the swirling chamber toward the bottom portion of the dust collecting chamber. Thus, the dust is reliably guided to the bottom portion, and the dust can be separated from the dust collection chamber disposed above the dust collection chamber to the outlet for returning the airflow to the swirl chamber.

さらに、この吸気口/排気筒の通気孔位置/集塵室との流入・流出口との高低差により、旋回室内で、吸気口からの流入気流と、集塵室から旋回室へ戻る気流との衝突を、排気筒の通気孔よりも下方で発生させることになるため、衝突により発生する乱流の影響によって、旋回室から集塵室へ向かう気流を阻害することを抑えることができ、スムーズな塵埃移送性を確保することができるようになり、確実に旋回室とは別室にて塵埃を集塵できるようになるため、旋回室内で含塵空気が旋回しつづけることはないため、塵埃分離性をさらに向上させることができるようになる。   Furthermore, due to the difference in height between the inlet / exhaust vent position / inlet / outlet with the dust collection chamber, the inflow airflow from the intake port and the airflow returning from the dust collection chamber to the swirl chamber Is generated below the vent hole of the exhaust stack, so that it is possible to suppress the obstruction of the air flow from the swirl chamber to the dust collection chamber due to the influence of the turbulent flow generated by the collision. Dust transportability can be ensured, and dust can be collected in a separate chamber from the swirl chamber, so that the dust-containing air does not continue to swirl in the swirl chamber. The performance can be further improved.

第2の発明は、旋回室内部に、集塵室の一部をオーバーラップさせる構成としたものであり、これにより、集塵室内は一様な略円筒面のままであるため、旋回気流の旋回性を阻害させることなく、また、旋回室内においても、旋回室と集塵室との連通部に構成している区画壁によって旋回気流経路を形成しているため、旋回気流の流れを阻害させることなく、集塵ケースの小型化を図ることができる。   In the second aspect of the invention, a part of the dust collection chamber is overlapped with the inside of the swirl chamber. Thereby, the dust collection chamber remains a uniform substantially cylindrical surface. Without disturbing the swirlability, and also in the swirl chamber, the swirl airflow path is formed by the partition wall formed in the communication portion between the swirl chamber and the dust collecting chamber, so the flow of the swirl airflow is obstructed Therefore, the dust collection case can be reduced in size.

第3の発明は、旋回室中心付近に配置した排気筒と、前記旋回室の底中心付近に設けた集塵室への流入口/流出口とを結ぶ区画壁とを連ねて構成したものであり、これにより、
旋回室内において、筒内中央に発生する気流が無くなるため、旋回室内での気流の衝突による乱れを抑えることができ、よりスムーズに旋回室から集塵室へと含塵空気を誘引させることができるようになる。
According to a third aspect of the present invention, an exhaust pipe disposed near the center of the swirl chamber and a partition wall connecting the inlet / outlet to the dust collecting chamber provided near the bottom center of the swirl chamber are connected. Yes, this
Since there is no airflow generated in the center of the cylinder in the swirl chamber, turbulence caused by collision of airflow in the swirl chamber can be suppressed, and dust-containing air can be attracted more smoothly from the swirl chamber to the dust collection chamber. It becomes like this.

第4の発明は、旋回室の上方に、排気筒を通過した空気をさらに塵埃分離する第2の塵埃分離手段を配し、第2の塵埃分離手段で分離した塵埃を、排気筒の内側、区画壁の内側を連通して、前記旋回室の下方に設けた細塵Boxへと導いて溜めるように構成したものであり、これにより、2段階で分離したそれぞれの塵埃は、集塵ケースの底部分に並設して溜めることができるため、溜まった塵埃を捨てる際、一度に処理することができるようになる。   According to a fourth aspect of the present invention, a second dust separation means for further separating the air that has passed through the exhaust pipe is disposed above the swirl chamber, and the dust separated by the second dust separation means is disposed inside the exhaust pipe, The inside of the partition wall communicates with the fine dust box provided below the swirl chamber and is stored so that each dust separated in two stages is stored in the dust collecting case. Since they can be stored side by side at the bottom, when the accumulated dust is thrown away, it can be processed at once.

第5の発明は、集塵室から旋回室への流出口には通気格子を設けたものであり、これにより、集塵室から旋回室へと戻る気流に塵埃が乗っていたとしても、この通気格子でろ過することができる。   According to a fifth aspect of the present invention, a ventilation grid is provided at the outlet from the dust collection chamber to the swirl chamber, so that even if dust is on the airflow returning from the dust collection chamber to the swirl chamber, Can be filtered through a ventilation grid.

第6の発明は、流出口の通気格子の孔形状を、集塵室から旋回室に向かって下方斜め方向に開口したものであり、これにより、集塵室から旋回室へと戻る気流は上方斜めに向かって流れに対し通気格子の開口方向が対称となっているため、通気格子に塵埃が付着せずに、塵埃分離した空気だけが通過することになる。   According to a sixth aspect of the present invention, the hole shape of the vent lattice at the outlet is opened obliquely downward from the dust collection chamber toward the swirl chamber, whereby the air flow returning from the dust collection chamber to the swirl chamber is upward. Since the opening direction of the ventilation grid is symmetric with respect to the flow obliquely, dust does not adhere to the ventilation grid, and only dust-separated air passes.

第7の発明は、流出口を、流入口よりも高い位置に配置するように構成したものであり、これにより、集塵室内での塵埃と空気との分離性を向上させることができる。   7th invention is comprised so that an outflow port may be arrange | positioned in a position higher than an inflow port, Thereby, the separability of the dust and air in a dust collection chamber can be improved.

第8の発明は、吸気口の開口高さに対して、排気筒の通気孔形成範囲との重なりが40%以下となるように配置したものであり、これにより、旋回気流の斜め下方向へ流れる気流成分を確実に発生させることができ、旋回気流による集塵室側へのスムーズな塵埃移送が行えるようになる。   In the eighth aspect of the invention, the overlap with the vent hole formation range of the exhaust pipe is 40% or less with respect to the opening height of the intake port, and thereby, the swirling airflow is obliquely downward. The flowing airflow component can be reliably generated, and smooth dust transfer to the dust collecting chamber side by the swirling airflow can be performed.

集塵ケース3の旋回室1は、略円筒形状の筒体の外周円に対して接線方向となるように取り付けた吸引通路を有する吸気口5と、中心には第2集塵ケース4に連通する略円筒状の排気筒6を配している。この排気筒6の外周側面にはメッシュフィルターやエッチングフィルター等の濾過フィルターによる通気部7を構成しており、粗塵が第2集塵ケース4側へと確実に通り抜けないようにしている。旋回室1では、吸気口5と排気筒6との位置関係、ならびに吸気口5より旋回室1の円筒内壁に沿って流入させることにより(図3)、吸気口5より直線気流として旋回室1に流入した含塵空気は、旋回気流となって旋回するようになる。排気筒6の内側空間は、第2集塵ケース4に連通しており、排気筒6の通気部7を通過した空気は、第2集塵ケース4へと流れていく。   The swirl chamber 1 of the dust collection case 3 communicates with an intake port 5 having a suction passage attached so as to be in a tangential direction with respect to the outer circumferential circle of the substantially cylindrical cylindrical body, and communicated with the second dust collection case 4 at the center. A substantially cylindrical exhaust cylinder 6 is arranged. A ventilation portion 7 made of a filtration filter such as a mesh filter or an etching filter is formed on the outer peripheral side surface of the exhaust tube 6 to prevent coarse dust from passing through to the second dust collection case 4 side. In the swirl chamber 1, the positional relationship between the intake port 5 and the exhaust pipe 6, and the flow from the intake port 5 along the cylindrical inner wall of the swirl chamber 1 (FIG. 3), the swirl chamber 1 as a straight airflow from the intake port 5. The dust-containing air that has flowed into the air turns as a swirling airflow. The inner space of the exhaust tube 6 communicates with the second dust collection case 4, and the air that has passed through the ventilation part 7 of the exhaust tube 6 flows to the second dust collection case 4.

次に、集塵室2は、図に示すように、旋回室1の内径とほぼ同等の内径とした略円筒形状の集塵室2を、旋回室1の下方にそれぞれの中心軸を平行にズラした位置で配置させて
おり、かつ、集塵室2の上端の一部を旋回室1の内部に食い込ませた構成としている。つまり、旋回室1と集塵室2と重なる部分は、図4に示すように、旋回室1側が凹状となり、集塵室2側は略円筒形状となる隔壁8を設けている。そして、旋回室1の外周と集塵室2の外周とが交差する一方においては、互いの外周円に接するように直線状の壁9を設けており、隔壁8の側面部分は、旋回室1の外周と交わる両側付近に連通口を設け、それぞれの連通口の間口縁を外周壁に一致させている。ここで、この2つの連通口の一方は、旋回室1で旋回する気流が集塵室2へと流れ込む流入口10であり、もう一方が、集塵室2から旋回室1へと戻る気流の流出口11として構成したものであり、流入口10は、先述した旋回室1の外周と集塵室2の外周とを接するように結んだ直線状の壁9を設けた側に構成している。
Next, as shown in the figure, the dust collection chamber 2 is configured so that a substantially cylindrical dust collection chamber 2 having an inner diameter substantially equal to the inner diameter of the swirl chamber 1 is placed below the swirl chamber 1 with the respective central axes in parallel. It is arranged at a shifted position, and a part of the upper end of the dust collection chamber 2 is bitten into the swirl chamber 1. That is, as shown in FIG. 4, the portion overlapping the swirl chamber 1 and the dust collection chamber 2 is provided with a partition wall 8 having a concave shape on the swirl chamber 1 side and a substantially cylindrical shape on the dust collection chamber 2 side. Then, on the one side where the outer periphery of the swirl chamber 1 and the outer periphery of the dust collection chamber 2 intersect, a straight wall 9 is provided so as to contact each other's outer peripheral circle, and the side surface portion of the partition wall 8 is the swirl chamber 1. A communication port is provided in the vicinity of both sides intersecting the outer periphery of each of the two, and the edge of each communication port is made to coincide with the outer peripheral wall. Here, one of the two communication ports is an inlet 10 through which the airflow swirling in the swirl chamber 1 flows into the dust collection chamber 2, and the other is an airflow returning from the dust collection chamber 2 to the swirl chamber 1. The inflow port 10 is configured as the outflow port 11, and the inflow port 10 is configured on the side provided with the linear wall 9 that connects the outer periphery of the swirl chamber 1 and the outer periphery of the dust collection chamber 2. .

また、旋回室1の排気筒6の下方を底面まで延長するように区画壁12を設け、区画壁12と集塵室の隔壁8とが重なる構成としており、流入口10/流出口11は、旋回室1と集塵室2の外周壁が交わる稜線から、集塵室の隔壁8と区画壁12とが交わる稜線までの範囲で開口させている。また、流出口11には、格子の開口間口の大きさを1mm〜2mm画で設定した通気格子13を形成し、集塵室2の底部分は開口しており、回動自在に軸支した底蓋14でエアタイト性を確保しながら塞ぐ構成としている。通気格子13の開口間口のサイズは、実験結果より、開口間口の大きさを3mm以上で設定すると、リントといった細かい埃は、格子に引っ掛からずに旋回室1側へと通り抜けてしまう傾向が見られ出すようなったが、開口間口を2mm画で設定すると、格子にリントが引っ掛かり、旋回室1側への通り抜けが大幅に抑えることができたため、樹脂一体成形で可能な1mm〜2mm画のサイズ設定としている。   Further, a partition wall 12 is provided so as to extend the bottom of the exhaust tube 6 of the swirl chamber 1 to the bottom surface, and the partition wall 12 and the partition wall 8 of the dust collection chamber overlap each other. It opens in the range from the ridgeline where the outer peripheral wall of the swirl chamber 1 and the dust collection chamber 2 intersects to the ridgeline where the partition wall 8 and the partition wall 12 of the dust collection chamber intersect. In addition, the outlet 11 is formed with a ventilation grid 13 in which the size of the opening between the grids is set to 1 mm to 2 mm, and the bottom portion of the dust collecting chamber 2 is open and pivotally supported. The bottom lid 14 is closed while ensuring air tightness. From the experimental results, it can be seen from the experimental results that when the size of the opening front is set to 3 mm or more, fine dust such as lint tends to pass through the swirl chamber 1 without being caught by the lattice. However, when the opening front was set to 2 mm, lint was caught on the lattice, and the passage to the swirl chamber 1 side could be greatly suppressed. It is said.

旋回室1の吸気口5、排気筒6の通気部7、および旋回室1と集塵室2とを連通する流入口10/流出口11は、図2に示すように、上から順に高さ位置をズラした配置としており、これにより、吸気口5より流入した含塵空気は、吸気口5より斜め下方に旋回室1を旋回しながら流入口10へと進入し、そのまま延長して、集塵室2内を斜め下方に旋回しながら集塵室の底位置まで流れていく。そして、重みのある粗塵は、集塵室2の底部分でそのまま旋回し続け、粗塵を分離した気流は旋回しながら上昇し、この上昇気流に乗ったリント等の細かい埃は、流出口11の通気格子13に引っ掛かり、さらに塵埃分離した状態の空気が、通気格子13を通り抜けて旋回室1へと戻り、旋回室1を旋回しながら、排気筒6の通気部7を抜けて第2集塵ケース4へと流れていく(図5)。ここで、集塵室2内では、粗塵がその重みにより底位置で旋回し続けると、絡まり合いながらマリモのように固まって行き、そこに細塵も一緒に絡まり合うため、この作用により、塵埃と空気とが分離される。次に、集塵室2内を流出口11に向かって旋回上昇する気流には、幾分、リント等の細かい塵埃が乗っているが、リントは2mm画間口の通気格子13で引っ掛かり、それが堆積するとリントがフィルターの役目をするようになり、旋回室1側への細塵の通過をより抑えることができるようになる。つまり、リントが堆積すると不織布フィルターに似た状態になるためである。   As shown in FIG. 2, the intake port 5 of the swirl chamber 1, the ventilation portion 7 of the exhaust pipe 6, and the inflow port 10 / outlet port 11 that communicates the swirl chamber 1 and the dust collection chamber 2 have height in order from the top. As a result, the dust-containing air that has flowed in from the intake port 5 enters the inlet 10 while swirling the swirl chamber 1 obliquely downward from the intake port 5 and is extended and collected. It flows to the bottom position of the dust collecting chamber while turning in the dust chamber 2 obliquely downward. The heavy coarse dust continues to swirl as it is in the bottom portion of the dust collecting chamber 2, and the airflow from which the coarse dust is separated rises while swirling, and fine dust such as lint riding on this ascending airflow is discharged from the outlet. The air in a state where the air is caught in the ventilation grid 13 and further separated by dust passes through the ventilation grid 13 and returns to the swirl chamber 1. It flows to the dust collecting case 4 (FIG. 5). Here, in the dust collection chamber 2, when coarse dust keeps swirling at the bottom position due to its weight, it will solidify like marimo while entangled, and fine dust will also get entangled there together. Dust and air are separated. Next, the dust flowing in the dust collection chamber 2 toward the outlet 11 is somewhat covered with fine dust such as lint, but the lint is caught by the ventilation grid 13 at the 2 mm gap and it is If it accumulates, a lint will act as a filter and the passage of fine dust to the swirl chamber 1 side can be further suppressed. That is, when lint accumulates, it becomes a state similar to a nonwoven fabric filter.

このように、旋回室1内において、排気筒6/区画壁12と外周壁との間で、集塵室2への流入口10まで通じる旋回経路15を形成した状態となるため(図6)、よりスムーズに旋回室1から集塵室2へと旋回気流を導くことができる。従来のサイクロン構成では、旋回室1と集塵室2とを同軸上に配置させることが一般的であるが、旋回室1と集塵室2とを平行にズラした状態としても、旋回室1と集塵室2とが上下となる配置、つまり、斜め上下方向の位置関係とし、かつ、旋回室1と集塵室2との間で、楕円軌道を描くように気流の入口と出口を設けることで、一般的なサイクロンの気流と類似した遠心旋回気流を形成することができるようになる。   Thus, in the swirl chamber 1, a swirl path 15 leading to the inlet 10 to the dust collection chamber 2 is formed between the exhaust pipe 6 / the partition wall 12 and the outer peripheral wall (FIG. 6). Thus, the swirling airflow can be guided from the swirling chamber 1 to the dust collecting chamber 2 more smoothly. In the conventional cyclone configuration, the swirl chamber 1 and the dust collection chamber 2 are generally arranged coaxially. However, even if the swirl chamber 1 and the dust collection chamber 2 are displaced in parallel, the swirl chamber 1 And the dust collection chamber 2 are arranged vertically, that is, in an oblique vertical direction, and an air flow inlet and outlet are provided between the swirl chamber 1 and the dust collection chamber 2 so as to draw an elliptical orbit. Thus, it becomes possible to form a centrifugal swirl air flow similar to a general cyclone air flow.

そして、第2集塵ケース4には、第2の塵埃分離手段として不織布フィルター16をプ
リーツ状に折ったものを配置し、排気筒6から抜けてきた微小な細塵をこの不織布フィルタ16ーにて濾過し、きれいになった空気のみが不織布フィルター16を通過して、電動送風機へと導かれていく。ここで、不織布フィルター16の下流側には、フィルター表面に衝撃振動を与える除塵子(図示せず)を取り付けており、吸引運転後、除塵子と連結させたサイクロン集塵装置に内蔵したリニア駆動部(図示せず)からの往復運動により、フィルター表面を除塵子で叩き、不織布フィルター16の表面に付着した細塵を衝撃により落としている。この叩き落とした細塵は、排気筒6、区画壁12の内側空間を通って、旋回室1下方に設けた区画壁12の内側と連通させた細塵Box17まで落ちて溜まるようにしている。ここで、細塵Box17は、集塵室2と隣接して配置しており、細塵Box17の底は開口しており、底蓋14によって集塵室2と同時に塞ぐ構成としている(図7)。
In the second dust collecting case 4, a non-woven filter 16 folded in a pleat shape is arranged as a second dust separating means, and minute fine dust that has come out of the exhaust tube 6 is placed in the non-woven filter 16. Only the air that has been filtered and cleaned passes through the nonwoven fabric filter 16 and is guided to the electric blower. Here, on the downstream side of the non-woven fabric filter 16, a dust remover (not shown) that gives shock vibration to the filter surface is attached, and after the suction operation, a linear drive built in a cyclone dust collector connected to the dust remover By reciprocating movement from a portion (not shown), the filter surface is hit with a dust remover, and fine dust adhering to the surface of the nonwoven fabric filter 16 is dropped by impact. The fine dust that has been knocked down passes through the inner space of the exhaust pipe 6 and the partition wall 12, and falls to the fine dust box 17 that communicates with the inside of the partition wall 12 provided below the swirl chamber 1. Here, the fine dust box 17 is disposed adjacent to the dust collection chamber 2, the bottom of the fine dust box 17 is opened, and is closed simultaneously with the dust collection chamber 2 by the bottom lid 14 (FIG. 7). .

また、流出口11に設けた通気格子13の孔形状において、図8に示すように、集塵室2から旋回室1に向かった下方斜め方向に開口した孔形状にすれば、集塵室2を旋回上昇する気流の方向と対称になるため、リントの引っ掛かりをより抑えることができる。   Further, in the hole shape of the ventilation grid 13 provided at the outlet port 11, if the hole shape is opened in a diagonally downward direction from the dust collection chamber 2 toward the swirl chamber 1 as shown in FIG. 8, the dust collection chamber 2. Since it becomes symmetrical with the direction of the airflow that swirls and rises, lint catching can be further suppressed.

さらに、図9に示すように、集塵室2の流出口11の高さ位置を、流入口10よりも上方に位置するように配置すれば、集塵室2内を舞い上がる旋回気流経路が長くなるため、舞い上がり気流に乗った細塵の塵埃分離性を上げることができる。   Furthermore, as shown in FIG. 9, if the height position of the outlet 11 of the dust collection chamber 2 is positioned higher than the inlet 10, the swirling air flow path that rises in the dust collection chamber 2 is long. Therefore, it is possible to improve the dust separation of fine dust riding on the rising airflow.

またさらに、図10に示すように、吸気口5の開口と排気筒6の通気部7とのオーバーラップにおいて、排気筒6の通気部7の上端が、吸気口下縁より吸気口高さの約40%となるように配置することによって、旋回室1に流入した含塵気流に、より下降気流成分を与えることができるため、旋回室1での旋回数を減らして、集塵室2の流入口10へと誘引させることができ、旋回室1での塵埃分離効率を向上させることができる。   Furthermore, as shown in FIG. 10, in the overlap between the opening of the intake port 5 and the ventilation part 7 of the exhaust pipe 6, the upper end of the ventilation part 7 of the exhaust pipe 6 is higher than the intake port lower edge. By arranging to be about 40%, it is possible to give a descending airflow component to the dust-containing airflow that has flowed into the swirl chamber 1, so the number of swirls in the swirl chamber 1 is reduced, and the dust collection chamber 2 It can be attracted to the inflow port 10 and the dust separation efficiency in the swirl chamber 1 can be improved.

ここで、本実施の形態において、旋回室1に隣接し、かつ集塵室2の上方に位置する空間部18は(図2)、上述した除塵子のリニア駆動部を配置や、フィルター・メンテナンス用のブラシを収納するなどに活用でき、サイクロン集塵装置の外観形状をデザイン的にスッキリとさせた状態で構成させることができる。   Here, in the present embodiment, the space 18 adjacent to the swirl chamber 1 and located above the dust collection chamber 2 (FIG. 2) is provided with the above-described linear drive unit for the dust remover, filter maintenance, and the like. It can be used to store a brush for use, and can be configured with the appearance of the cyclone dust collector refreshed in design.

以上、一般的なサイクロン形態に対し、完全に旋回室1と集塵室2とを連通口を有すのみで区画形成した形態において、上記の構成をすることにより、従来と同様の遠心旋回軌道を形成可能としながら、別室の集塵室2へと旋回気流を誘導して、集塵室2で塵埃を堆積させるようにすることができるようになるため、空気と塵埃との分離をさらに向上させるサイクロン集塵装置を実現することができるようになる。   As described above, in the form in which the swirl chamber 1 and the dust collection chamber 2 are completely formed by only having a communication port with respect to the general cyclone form, the same centrifugal swirl trajectory as in the prior art is achieved by the above configuration. Can be formed, and it is possible to induce a swirling air flow to the dust collecting chamber 2 in a separate chamber so that dust is accumulated in the dust collecting chamber 2, so that the separation of air and dust is further improved. A cyclone dust collecting device can be realized.

以上のように、本発明にかかるサイクロン集塵装置は、含塵空気を旋回させる略円筒状の旋回室とは別室に、斜め下方に隣接して連通した集塵室を設け、吸気口/排気筒/集塵室への流入/流出口の高さ位置関係、ならびに、旋回室から集塵室への流入/流出口において旋回経路を形成する区画壁を旋回室内に設けたことで、斜め下方に旋回する気流を発生させ、旋回室の吸気口から隣接させた集塵室の底付近とを結んだ延長上に旋回気流を形成するようにしたため、隣接させた集塵室へは気流をスムーズに誘引させることができるようになり、集塵室内で塵埃は底部分まで確実に誘導され、集塵室上方に配置される集塵室から旋回室へ気流を戻す流出口までの間で塵埃を分離し、確実に旋回室とは別室にて塵埃を集塵できるようになり、旋回室内で含塵空気が旋回しつづけることはないため、塵埃分離性をさらに向上させることができるようになる。   As described above, the cyclone dust collecting apparatus according to the present invention is provided with a dust collecting chamber that is communicated obliquely downward and in a separate chamber from a substantially cylindrical swirling chamber that swirls dust-containing air. The height position of the inflow / outflow to the cylinder / dust collection chamber and the partition wall that forms the swirl path at the inflow / outflow from the swirl chamber to the dust collection chamber are provided diagonally downward A swirling airflow is generated on the extension that connects the vicinity of the bottom of the dust collection chamber adjacent to the swirl chamber intake port from the air inlet of the swirl chamber, so that the airflow is smooth to the adjacent dust collection chamber. The dust is surely guided to the bottom in the dust collection chamber, and the dust is collected between the dust collection chamber located above the dust collection chamber and the outlet that returns the airflow to the swirl chamber. It can be separated and reliably collected in a separate chamber from the swirl chamber. For dust-containing air in the room will not continue to pivot, it is possible to further improve the dust separation properties.
