Description

本発明は、電気集塵機の集塵部に関する。 The present invention relates to a dust collecting unit of an electric dust collector.

室内の空気を吸引し、吸引した空気から塵埃を除去する電気集塵機のなかには、塵埃に電荷を帯電させる荷電部と、帯電させた塵埃を捕集する集塵部とを備えたものがある。集塵部としては、平板状の高圧電極と平板状の接地電極とを、互いに平行となるよう交互に配置した構成のものが知られている。 Some electrostatic precipitators that suck the air in the room and remove the dust from the sucked air include a charged part that charges the dust and a dust collector that collects the charged dust. As the dust collecting portion, a structure in which a flat plate-shaped high-voltage electrode and a flat plate-shaped ground electrode are alternately arranged so as to be parallel to each other is known.

かかる電気集塵機の集塵部の一例として、高圧電極に給電する給電部材を、高圧電極の両側端部にそれぞれ接触するように配置するとともに、これら２つの給電部材に接触する電圧維持部材である導通部材を配置したものがある。かかる構成により、高圧電極に対し、両端側から均一な電圧を印加できるようにしている（例えば、特許文献１を参照）。 As an example of the dust collecting portion of such an electrostatic precipitator, a feeding member for feeding power to the high-voltage electrode is arranged so as to be in contact with both end portions of the high-voltage electrode, and conduction is a voltage maintaining member contacting these two feeding members. Some have members arranged. With such a configuration, a uniform voltage can be applied to the high-voltage electrode from both ends (see, for example, Patent Document 1).

しかしながら、特許文献１にあっては、異極である導通部材と接地電極との距離が、空間距離においても沿面距離においても小さくなるため、通部材と接地電極間で短絡が発生してしまうおそれがある。他方、導通部材と接地電極との距離を大きくすれば、導通部材と接地電極間の短絡は発生しにくくなるものの、集塵部が大型化してしまうという問題が生じる。 However, in Patent Document 1, since the distance between the conductive member and the ground electrode, which are different poles, becomes small in both the spatial distance and the creepage distance, a short circuit may occur between the through member and the ground electrode. There is. On the other hand, if the distance between the conductive member and the ground electrode is increased, a short circuit between the conductive member and the ground electrode is less likely to occur, but there arises a problem that the dust collecting portion becomes large.

開示の技術は、上記に鑑みてなされたものであって、導通部材と接地電極間の短絡を防止するとともに、集塵部の大型化を抑制することのできる電気集塵機の集塵部を提供することを目的とする。 The disclosed technique has been made in view of the above, and provides a dust collector of an electric dust collector capable of preventing a short circuit between a conductive member and a ground electrode and suppressing an increase in the size of the dust collector.

In addition, the components according to the following description include those that can be easily replaced by those skilled in the art, or those that are substantially the same, that is, those having a so-called equal range.

まず、実施例の電気集塵機の集塵部を備える空気清浄機の概略について説明する。図１は、実施例の空気清浄機１の概略構成図である。一実施例である空気清浄機１は、図１に示すように、空気を清浄化するための装置類を収納するとともに、室内の空気を吸引する吸込口１１と、清浄化された空気を室内に吹き出す吹出口１２とが形成された筐体１０を備える。筐体１０は、合成樹脂材で成形された複数のパネルによって略直方体状に形成されている。 First, an outline of an air purifier including a dust collecting unit of the electrostatic precipitator of the embodiment will be described. FIG. 1 is a schematic configuration diagram of the air purifier 1 of the embodiment. As shown in FIG. 1, the air purifier 1 as an embodiment houses a device for purifying air, a suction port 11 for sucking indoor air, and an indoor air purifier 1. It is provided with a housing 10 in which an air outlet 12 is formed. The housing 10 is formed in a substantially rectangular parallelepiped shape by a plurality of panels formed of a synthetic resin material.

筐体１０内には、吸引された空気から大きな塵埃を除去するプレフィルタ１４と、プレフィルタ１４を通過した空気中の塵埃を電気的に集塵する複数の電気集塵機２と、電気集塵機２を通過した空気を脱臭処理する脱臭フィルタ５とが設けられる。 Inside the housing 10, a pre-filter 14 that removes large dust from the sucked air, a plurality of electrostatic precipitators 2 that electrically collect dust in the air that has passed through the pre-filter 14, and an electric dust collector 2 are provided. A deodorizing filter 5 for deodorizing the passed air is provided.

プレフィルタ１４は、例えば糸状のＰＥＴ材を編みこんだ網目構造を有し、図示しない樹脂枠で保持されており、筐体１０の内部に吸い込まれた空気に含まれている比較的大きな塵埃を捕集する。脱臭フィルタ５は、触媒フィルタを有し、プレフィルタ１４および電気集塵機２で塵埃が除かれた後、触媒フィルタで例えばアンモニアやメチルメルカプタン等の臭気成分やホルムアルデヒド等の有害成分を取り除く脱臭処理を行う。なお、触媒フィルタは、加熱により臭気の吸着機能が再生できる加熱再生型の構造を有することが好ましい。 The prefilter 14 has, for example, a mesh structure in which a thread-like PET material is woven, and is held by a resin frame (not shown), and relatively large dust contained in the air sucked into the housing 10 is removed. Collect. The deodorizing filter 5 has a catalytic filter, and after dust is removed by the pre-filter 14 and the electrostatic precipitator 2, the deodorizing treatment is performed to remove odorous components such as ammonia and methyl mercaptan and harmful components such as formaldehyde with the catalytic filter. .. The catalyst filter preferably has a heat regeneration type structure in which the odor adsorption function can be regenerated by heating.

電気集塵機２は、本実施例においては筐体１０内に３つ上下に配置されている。各電気集塵機２は、後に詳述する荷電部３と集塵部４とを有し、荷電部３には、荷電部３の電極に電力を供給する荷電部用高圧電源３０が設けられる。 In this embodiment, three electrostatic precipitators 2 are arranged one above the other in the housing 10. Each electrostatic precipitator 2 has a charged unit 3 and a dust collecting unit 4, which will be described in detail later, and the charged unit 3 is provided with a high-pressure power supply 30 for the charged unit that supplies electric power to the electrodes of the charged unit 3.

また、筐体１０内には、脱臭フィルタ５の下流側に配置されるファン６と、ファン６を回転させるモータ６１と、電気集塵機２やモータ６１を制御する制御部を有する電源制御基板７とが設けられる。さらに、筐体１０内には、電気集塵機２の集塵部４に電力を供給する集塵部用高圧電源４０と、吸込口１１から吸引された空気の塵埃濃度を検出する埃センサ１３とが設けられる。なお、筐体１０には、運転開始操作、運転停止操作、風量設定などを行う操作部（図示せず）と接続する操作表示基板１５が設けられる。なお、操作部は、筐体１０の上面部に設けられており、電源ボタンや運転モード切り換えボタン等の空気清浄機１を操作するボタンが配置されるとともに、空気清浄機１の運転状態や埃センサ１３等における検出結果を表示する表示部が配置される。 Further, in the housing 10, a fan 6 arranged on the downstream side of the deodorizing filter 5, a motor 61 for rotating the fan 6, and a power supply control board 7 having a control unit for controlling the electrostatic precipitator 2 and the motor 61 are provided. Is provided. Further, in the housing 10, a high-voltage power supply 40 for the dust collecting unit that supplies electric power to the dust collecting unit 4 of the electrostatic precipitator 2 and a dust sensor 13 that detects the dust concentration of the air sucked from the suction port 11 are provided. It will be provided. The housing 10 is provided with an operation display board 15 connected to an operation unit (not shown) for performing an operation start operation, an operation stop operation, an air volume setting, and the like. The operation unit is provided on the upper surface of the housing 10, and buttons for operating the air purifier 1 such as a power button and an operation mode switching button are arranged, and the operating state and dust of the air purifier 1 are arranged. A display unit for displaying the detection result of the sensor 13 or the like is arranged.

こうして、図中の矢印ｆで示されるように、吸込口１１から吸引された室内の空気は、空気中の塵埃がプレフィルタ１４と電気集塵機２とにより捕集されることで除塵される。そして、清浄化された清浄空気が吹出口１２から室内に吹き出される。特に、本実施例に係る空気清浄機１は、脱臭フィルタ５を備えているため、脱臭効果も奏する。 In this way, as shown by the arrow f in the figure, the indoor air sucked from the suction port 11 is removed by collecting the dust in the air by the pre-filter 14 and the electrostatic precipitator 2. Then, the purified clean air is blown into the room from the outlet 12. In particular, since the air purifier 1 according to the present embodiment includes the deodorizing filter 5, it also has a deodorizing effect.

ここで、電気集塵機２の集塵作用について簡単に説明する。電気集塵機２の荷電部３を構成する荷電部放電電極（不図示）に予め設定された正極の高電圧（例えば＋４．７ｋＶ）を印加し、荷電部対向電極４１２（図２参照）を荷電部用高圧電源３０の接地極（アース）に接続することで、荷電部放電電極と荷電部対向電極４１２との間でコロナ放電が起こる。すると、荷電部放電電極と荷電部対向電極４１２との間には、電子と空気分子が正に帯電したイオンが満たされる。そして、正イオンで満たされた空間を塵埃が通過する際に、その通過時間と荷電部放電電極と荷電部対向電極４１２とで作られる電界の強さに応じて、イオンと塵埃の衝突による電荷の移動が起こり、塵埃に正の電荷が帯電する。 Here, the dust collecting action of the electrostatic precipitator 2 will be briefly described. A preset high voltage (for example, +4.7 kV) of the positive electrode is applied to the charged part discharge electrode (not shown) constituting the charged part 3 of the electrostatic collector 2, and the charged part facing electrode 412 (see FIG. 2) is charged. By connecting to the ground electrode (earth) of the high-voltage power supply 30, corona discharge occurs between the charged portion discharge electrode and the charged portion facing electrode 412. Then, the charged portion discharge electrode and the charged portion facing electrode 412 are filled with ions positively charged with electrons and air molecules. Then, when the dust passes through the space filled with positive ions, the electric charge due to the collision between the ions and the dust depends on the passing time and the strength of the electric field generated by the charged part discharge electrode and the charged part facing electrode 412. Movement occurs, and the dust is positively charged.

一方、集塵部４の高圧電極部４２を構成する高圧電極４２１（図３参照）に予め設定された正極の高電圧（例えば＋４．７ｋＶ）を印加し、集塵部４の集塵電極部４３を構成する接地電極４３１（図３参照）を集塵部用高圧電源４０の接地極（アース）に接続すると、両電極間に所定の静電界が形成される。荷電部３で正に帯電した塵埃は、集塵部４に移動すると、同極性の高圧電極部４２の高圧電極４２１から反発する方向に斥力を受けるとともに、静電界により塵埃と反対極性の集塵電極部４３の接地電極４３１に吸引される方向に力を受け、集塵部４の接地電極４３１に到達する。そして、接地電極４３１に塵埃が付着することで、塵埃が捕集される。さらに、正に帯電されていた塵埃が接地電極４３１に触れると、塵埃に帯電していた電荷がアースに流される。そのため、帯電した塵埃の付着により集塵電極部４３の接地電極４３１が正極に帯電してしまうことが防止され、捕集力の低下が抑制されている。 On the other hand, a preset high voltage (for example, +4.7 kV) of the positive electrode is applied to the high voltage electrode 421 (see FIG. 3) constituting the high voltage electrode section 42 of the dust collecting section 4, and the dust collecting electrode section of the dust collecting section 4 is applied. When the ground electrode 431 (see FIG. 3) constituting the 43 is connected to the ground electrode (earth) of the high-voltage power supply 40 for the dust collecting portion, a predetermined electrostatic field is formed between the two electrodes. When the dust positively charged by the charged unit 3 moves to the dust collecting unit 4, it receives a repulsive force in the direction of repulsion from the high pressure electrode 421 of the high pressure electrode unit 42 having the same polarity, and also collects dust having the opposite polarity to the dust due to the electrostatic field. It receives a force in the direction of being sucked by the ground electrode 431 of the electrode unit 43 and reaches the ground electrode 431 of the dust collecting unit 4. Then, the dust adheres to the ground electrode 431, so that the dust is collected. Further, when the positively charged dust touches the ground electrode 431, the charge charged in the dust is flowed to the ground. Therefore, it is prevented that the ground electrode 431 of the dust collecting electrode portion 43 is charged to the positive electrode due to the adhesion of the charged dust, and the decrease in the collecting power is suppressed.

塵埃の捕集率を高める方法のひとつは、安定した集塵能力を維持することであり、そのために、電気集塵機２には、集塵部４の高圧電極部４２を構成する高圧電極４２１（図３参照）に安定した給電がなされる構成が求められる。 One of the methods for increasing the dust collection rate is to maintain a stable dust collection capacity, and for this purpose, the electrostatic precipitator 2 is equipped with a high-voltage electrode 421 that constitutes the high-voltage electrode portion 42 of the dust collector 4 (FIG. FIG. 3) is required to have a configuration in which stable power supply is provided.

The frame portion 41 is formed of a resin material having a volume resistivity of about 10 16 Ωm, such as PPE (polyphenylene ether). As shown in FIG. 3, the inner side surfaces of the first side walls 41a and 41a have a convex portion 413a for mounting the high-voltage electrode portion 42 and an engaging claw 413b for locking the high-voltage electrode portion 42. The high-voltage electrode mounting portions 413 are provided at predetermined intervals. On the other hand, on the inner side surfaces of the second side walls 41b and 41b, dust collecting electrode locking claws 414a for locking the dust collecting electrode portion 43 are formed on both ends. The dust collecting electrode locking claws 414a are also provided between the two high-voltage electrode mounting portions 413 and 413 on the inner side surfaces of the first side walls 41a and 41a.

高圧電極部４２は、半絶縁性の樹脂によりそれぞれ平板状に形成され、所定の間隔をあけて平行に設けられた複数の高圧電極４２１と、これら複数の高圧電極４２１の端部を連結する連結部４２３とにより、ブロック状に一体成形されている。高圧電極部４２は、例えばＰＡ（ポリアミド）やＡＢＳ樹脂を混合した体積抵抗率が１０１１Ωｍ程度の樹脂材料で形成される。また、集塵電極部４３も、それぞれ半絶縁性の樹脂により平板状に形成され、所定の間隔をあけて平行に設けられた複数の接地電極４３１と、これら複数の接地電極４３１の端部を連結する連結部４３３とにより、ブロック状に一体成形されている。接地電極部４３は、例えばＰＡ（ポリアミド）やＡＢＳ樹脂を混合した体積抵抗率が１０７Ωｍ程度の樹脂材料で形成される。そして、高圧電極部４２と集塵電極部４３とが、共に枠部４１に取付けられた状態では、高圧電極４２１と接地電極４３１とが所定の間隔をあけて交互に配置される。 The high-voltage electrode portion 42 is formed of a semi-insulating resin in a flat plate shape, and is connected to a plurality of high-voltage electrodes 421 provided in parallel at predetermined intervals and the ends of the plurality of high-voltage electrodes 421. It is integrally molded into a block shape by the portion 423. The high-voltage electrode portion 42 is formed of, for example, a resin material having a volume resistivity of about 10 11 Ωm mixed with PA (polyamide) or ABS resin. Further, the dust collecting electrode portion 43 is also formed in a flat plate shape with a semi-insulating resin, and is provided with a plurality of ground electrodes 431 arranged in parallel at predetermined intervals, and the ends of the plurality of ground electrodes 431. It is integrally molded into a block shape by the connecting portion 433 to be connected.

When the high-voltage electrode portion 42 and the dust collecting electrode portion 43 are both attached to the frame portion 41, the high-voltage electrodes 421 and the ground electrode 431 are alternately arranged at predetermined intervals.

また、詳しくは後述するが、高圧電極部４２の連結部４２３には、複数の高圧電極４２１に対して直交方向に溝部４２２が形成されている。かかる溝部４２２の中に給電部材４４が装着され、連結部４２３に接続された給電部材４４を介して高圧電極部４２へ集塵部用高圧電源４０から電力が供給される。また、集塵電極部４３の連結部４３３には、接地するために接触部４３２が設けられている。 Further, as will be described in detail later, a groove portion 422 is formed in the connecting portion 423 of the high voltage electrode portion 42 in the direction orthogonal to the plurality of high voltage electrodes 421. A power feeding member 44 is mounted in the groove portion 422, and power is supplied from the dust collecting portion high voltage power supply 40 to the high voltage electrode portion 42 via the feeding member 44 connected to the connecting portion 423. Further, the connecting portion 433 of the dust collecting electrode portion 43 is provided with a contact portion 432 for grounding.

高圧電極部４２の連結部４２３に形成された溝部４２２に装着される給電部材４４は、金属製の帯状体が板金加工され、図３に示すように略コ字状に形成されている。すなわち、給電部材４４は、第１の給電部４４１と、第２の給電部４４２と、第１の給電部４４１と第２の給電部４４２とを接続して導通させる導通部４４３とにより略コ字状に形成される。第１の給電部４４１は、高圧電極４２１の一端側から給電できるように高圧電極４２１の一端側に配置されている。第２の給電部４４２は、高圧電極４２１の他端側から給電できるように高圧電極４２１の他端側に配置される。そして、第１の給電部４４１と第２の給電部４４２とを接続する導通部４４３は、高圧電極４２１に対しても接地電極４３１に対しても平行に配置されている。 The power feeding member 44 mounted on the groove portion 422 formed in the connecting portion 423 of the high voltage electrode portion 42 is formed by sheet metal processing of a metal band-shaped body and is formed in a substantially U shape as shown in FIG. That is, the power feeding member 44 is substantially connected by a first feeding unit 441, a second feeding unit 442, and a conduction unit 443 that connects and conducts the first feeding unit 441 and the second feeding unit 442. It is formed in a character shape. The first power feeding unit 441 is arranged on one end side of the high voltage electrode 421 so that power can be supplied from one end side of the high voltage electrode 421. The second feeding unit 442 is arranged on the other end side of the high voltage electrode 421 so that power can be supplied from the other end side of the high voltage electrode 421. The conduction portion 443 connecting the first feeding portion 441 and the second feeding portion 442 is arranged in parallel to both the high voltage electrode 421 and the ground electrode 431.

給電部材４４の第１の給電部４４１の端部には、電圧を印加するための接触部４４４が形成されている。この接触部４４４は、給電部材４４が高圧電極部４２の連結部４２３に装着された状態では、図２に示すように、集塵部４の枠部４１の外側面に露出する。 A contact portion 444 for applying a voltage is formed at the end of the first feeding portion 441 of the feeding member 44. The contact portion 444 is exposed on the outer surface of the frame portion 41 of the dust collecting portion 4 as shown in FIG. 2 when the feeding member 44 is attached to the connecting portion 423 of the high voltage electrode portion 42.

ここで、高圧電極部４２に給電する給電部材４４の保持構造、すなわち、給電部材４４が高圧電極部４２の連結部４２３に形成された溝部４２２へ保持される構造について、図面に基づいてより具体的に説明する。図４は、電気集塵機２の集塵部４の高圧電極部４２を示す斜視図、図５は、電気集塵機２の集塵部４の高圧電極部４２の平面図である。また、図６は、高圧電極部４２の連結部４２３を示す斜視図である。また、図７は、給電部材４４が連結部４２３の溝部４２２に保持される一態様を説明するための模式図である。 Here, the holding structure of the feeding member 44 that feeds the high voltage electrode portion 42, that is, the structure in which the feeding member 44 is held by the groove portion 422 formed in the connecting portion 423 of the high voltage electrode portion 42, is more specific based on the drawings. To explain. FIG. 4 is a perspective view showing a high-pressure electrode portion 42 of the dust collecting unit 4 of the electrostatic precipitator 2, and FIG. 5 is a plan view of the high-pressure electrode portion 42 of the dust collecting unit 4 of the electrostatic precipitator 2. Further, FIG. 6 is a perspective view showing a connecting portion 423 of the high voltage electrode portion 42. Further, FIG. 7 is a schematic diagram for explaining one aspect in which the feeding member 44 is held in the groove portion 422 of the connecting portion 423.

図４に示すように、給電部材４４は、ブロック状に形成された高圧電極部４２の３つの側面を囲むように装着される。すなわち、図４および図５に示すように、複数の高圧電極４２１の端部を連結する連結部４２３には、枠部４１（図３参照）に設けられた高圧電極搭載部４１３と対応する複数のリブ４２４が外方へ突出するように形成されており、かかるリブ４２４と連結部４２３の側面との間に溝部４２２が形成されている。給電部材４４は、かかる溝部４２２内に挿入されて連結部４２３と接触し、高圧電極部４２への給電がなされる。 As shown in FIG. 4, the feeding member 44 is mounted so as to surround the three side surfaces of the high voltage electrode portion 42 formed in a block shape. That is, as shown in FIGS. 4 and 5, the connecting portion 423 connecting the ends of the plurality of high-voltage electrodes 421 corresponds to the plurality of high-voltage electrode mounting portions 413 provided in the frame portion 41 (see FIG. 3). The rib 424 is formed so as to project outward, and a groove portion 422 is formed between the rib 424 and the side surface of the connecting portion 423. The power feeding member 44 is inserted into the groove portion 422 and comes into contact with the connecting portion 423 to supply power to the high voltage electrode portion 42.

本実施例に係るリブ４２４は、図５に示すように、連結部４２３の中央に形成された中央リブ４２４ｄと、この中央リブ４２４ｄを挟んで左右対称に、第１のリブ４２４ａ、第２のリブ４２４ｂ、第３のリブ４２４ｃと３つずつ形成されている。すなわち、一側の連結部４２３に合計７つのリブ４２４が形成されている。 As shown in FIG. 5, the rib 424 according to the present embodiment has the central rib 424d formed in the center of the connecting portion 423 and the first rib 424a and the second rib 424a symmetrically with the central rib 424d interposed therebetween. Three ribs 424b and three third ribs 424c are formed. That is, a total of seven ribs 424 are formed on the connecting portion 423 on one side.

そして、かかるリブ４２４のうち、相対的に狭幅な第２のリブ４２４ｂを除いて、第１のリブ４２４ａ、第３のリブ４２４ｃ、および中央リブ４２４ｄの内側に、第１の突出部であるリブ側突出部４２５が溝部４２２に臨むように形成されている。他方、連結部４２３の側面には、高圧電極４２１の配列方向においてリブ側突出部４２５とはずれた位置に、第２の突出部である一対の連結部側突出部４２６，４２７が形成されている。そして、かかるリブ側突出部４２５と連結部側突出部４２６，４２７とにより、三点支持構造が形成される。こうして、給電部材４４の第１の給電部４４１（第２の給電部４４２）は、複数個所に設けられた三点支持構造により、各突出部（リブ側突出部４２５、連結部側突出部４２６、４２７）に密着した状態で支持される。 Then, among the ribs 424, the first protrusion is inside the first rib 424a, the third rib 424c, and the central rib 424d, except for the second rib 424b which is relatively narrow. The rib side protrusion 425 is formed so as to face the groove 422. On the other hand, on the side surface of the connecting portion 423, a pair of connecting portion side protruding portions 426, 427, which are the second protruding portions, are formed at positions separated from the rib side protruding portions 425 in the arrangement direction of the high voltage electrodes 421. .. Then, a three-point support structure is formed by the rib-side protrusions 425 and the connecting portion-side protrusions 426 and 427. In this way, the first feeding portion 441 (second feeding portion 442) of the feeding member 44 has each protruding portion (rib side protruding portion 425, connecting portion side protruding portion 426) due to the three-point support structure provided at a plurality of locations. It is supported in close contact with 427).

すなわち、図６等に示すように、第１のリブ４２４ａおよび第３のリブ４２４ｃおよび中央リブ４２４ｄの内側面にリブ側突出部４２５が形成されるとともに、このリブ側突出部４２５と対向する連結部４２３の側面に、高圧電極４２１の配列方向においてリブ側突出部４２５とずれた位置に一対の連結部側突出部４２６，４２７が形成されて三点支持構造が構成される。 That is, as shown in FIG. 6 and the like, a rib side protrusion 425 is formed on the inner side surface of the first rib 424a, the third rib 424c, and the central rib 424d, and the rib side protrusion 425 is connected to the rib side protrusion 425. A pair of connecting portion-side protrusions 426 and 427 are formed on the side surface of the portion 423 at positions deviated from the rib-side protrusions 425 in the arrangement direction of the high-voltage electrodes 421 to form a three-point support structure.

このように、給電部材４４の一方の側面に当接する第１の突出部であるリブ側突出部４２５と、給電部材４４の他方の側面に当接する第２の突出部である連結部側突出部４２６，４２７とは、給電部材４４を挟む位置であって、高圧電極４２１の配列方向において互いにずれた位置に設けられる。かかる第１の突出部と一対の第２の突出部とで構成される三点支持構造は、連結部４２３において均等な間隔で複数個所に設けられることが望ましいが、一か所に設けても構わない。 In this way, the rib-side protruding portion 425, which is the first protruding portion that abuts on one side surface of the feeding member 44, and the connecting portion-side protruding portion, which is the second protruding portion that abuts on the other side surface of the feeding member 44. The 426 and 427 are positions that sandwich the feeding member 44, and are provided at positions that are offset from each other in the arrangement direction of the high voltage electrodes 421. It is desirable that the three-point support structure composed of the first protrusion and the pair of second protrusions is provided at a plurality of locations at equal intervals in the connecting portion 423, but even if the three-point support structure is provided at one location. I do not care.

したがって、溝部４２２の対向する内側面それぞれには、一方の内側面から他方の内側面に向かって突出する突出部（リブ側突出部４２５および連結部側突出部４２６，４２７）が形成され、給電部材４４は、挟持部としての対向する突出部（リブ側突出部４２５と連結部側突出部４２６、４２７）同士で挟持されることになる。 Therefore, protrusions (rib side protrusions 425 and connection side protrusions 426, 427) projecting from one inner side surface toward the other inner side surface are formed on each of the facing inner surfaces of the groove portion 422, and power is supplied. The member 44 is sandwiched between facing protrusions (rib side protrusions 425 and connection portion side protrusions 426, 427) as holding portions.

ところで、図６に示すように、突出部（リブ側突出部４２５および連結部側突出部４２６，４２７）は、溝部４２２の深さ方向に沿ってリブ状に形成されている。そして、突出部における先端側、すなわち溝部４２２の開口側には、給電部材４４を溝部４２２の底部方向へ案内するテーパ部４２８が形成されている。このように、突出部を、所定の高さを有するリブ状に形成するとともに、先端側にはテーパ部４２８を設けたため、給電部材４４を溝部４２２へ装着する際に、円滑に挿入できるとともに、挿入した際には、突出部により給電部材４４の厚み方向へと加わる十分な押圧力で給電部材４４を挟持することができる。 By the way, as shown in FIG. 6, the protruding portions (rib-side protruding portions 425 and connecting portion-side protruding portions 426, 427) are formed in a rib shape along the depth direction of the groove portion 422. A tapered portion 428 that guides the feeding member 44 toward the bottom of the groove portion 422 is formed on the tip end side of the protruding portion, that is, on the opening side of the groove portion 422. As described above, since the protruding portion is formed in a rib shape having a predetermined height and the tapered portion 428 is provided on the tip side, the feeding member 44 can be smoothly inserted when the feeding member 44 is mounted on the groove portion 422. When inserted, the feeding member 44 can be sandwiched by a sufficient pressing force applied to the thickness direction of the feeding member 44 by the protruding portion.

図８Ａは、連結部４２３の溝部４２２を示す平面図、図８Ｂは、給電部材４４が連結部４２３の溝部４２２に保持された状態を示す平面図である。図８Ａに示すように、溝部４２２の幅をＷ、突出部（リブ側突出部４２５および連結部側突出部４２６，４２７）の各幅をそれぞれｄとするとともに、図８Ｂに示すように、給電部材４４の第１の給電部４４１（第２の給電部４４２）の厚みをｔとしたとする。その場合、例えば、以下の式が成立するように、給電部材４４の厚み、溝部４２２や突出部の幅などの寸法を決定することができる。
Ｗ－２ｄ＜ｔ＜Ｗ－ｄ・・・・（式１） FIG. 8A is a plan view showing the groove portion 422 of the connecting portion 423, and FIG. 8B is a plan view showing a state in which the feeding member 44 is held by the groove portion 422 of the connecting portion 423. As shown in FIG. 8A, the width of the groove portion 422 is W, the width of each of the protruding portions (rib side protruding portion 425 and the connecting portion side protruding portions 426, 427) is d, and as shown in FIG. 8B, power is supplied. It is assumed that the thickness of the first feeding portion 441 (second feeding portion 442) of the member 44 is t. In that case, for example, dimensions such as the thickness of the feeding member 44 and the width of the groove portion 422 and the protruding portion can be determined so that the following equation is established.
W-2d <t <Wd ... (Equation 1)

かかる寸法とすることにより、給電部材４４は、図８Ｂに示すように、リブ側突出部４２５および連結部側突出部４２６，４２７による３点支持によって、あたかも波状になるようにしっかりと押圧された状態で連結部４２３に接触することになる。しかも、板金で形成された給電部材４４は、波状に変形した状態から元の平板状に戻ろうとする復元力によって、更にリブ側突出部４２５および連結部側突出部４２６，４２７へと押し付けられる。そのため、給電部材４４が元の形状に戻ろうとして連結部４２３から離れてしまうことを抑制できるので、給電部材４４と高圧電極部４２との間で接触状態が変化することを防止することができる。したがって、給電部材４４と高圧電極部４２との接触状態の変化に起因する集塵性能の変動も防止でき、本実施例に係る電気集塵機２の集塵部４は、安定した集塵能力を発揮することができる。 With such dimensions, as shown in FIG. 8B, the feeding member 44 was firmly pressed so as to be wavy by the three-point support by the rib side protrusions 425 and the connecting portion side protrusions 426 and 427. It will come into contact with the connecting portion 423 in this state. Moreover, the feeding member 44 formed of sheet metal is further pressed against the rib-side protrusions 425 and the connecting portion-side protrusions 426 and 427 by the restoring force that tries to return to the original flat plate shape from the wavy deformed state. Therefore, it is possible to prevent the feeding member 44 from being separated from the connecting portion 423 in an attempt to return to the original shape, so that it is possible to prevent the contact state from changing between the feeding member 44 and the high voltage electrode portion 42. .. Therefore, it is possible to prevent fluctuations in the dust collection performance due to changes in the contact state between the power feeding member 44 and the high-voltage electrode unit 42, and the dust collection unit 4 of the electric dust collector 2 according to the present embodiment exhibits a stable dust collection capacity. can do.

また、図７に示すように、溝部４２２を形成する複数のリブ４２４の連結部４２３の側面からの突出長さＤは、給電部材４４を突出部が確実に挟持可能な長さを確保できるだけでよい。そのため、突出長さＤが大きくなるのを抑制することができるので、高圧電極部４２が外方へ大きくなるのを抑えることが可能となり、集塵部４、ひいては電気集塵機２、さらには空気清浄機１の大型化を抑制することができる。 Further, as shown in FIG. 7, the protrusion length D from the side surface of the connecting portion 423 of the plurality of ribs 424 forming the groove portion 422 can only secure a length that allows the protrusion portion to reliably sandwich the feeding member 44. good.

Is located in. On the other hand, regarding the conduction section 443 connecting the first feeding section 441 and the second feeding section 442, the conduction section arranging section 410 provided in the frame section 41 holding the high voltage electrode section 42 and the dust collecting electrode section 43. Be placed. A first rib portion 415 (rib 4151 and rib 4152) erected from the frame portion 41 is arranged between the conduction portion arranging portion 410 and the ground electrode 431.

また、図１０および図１１に示すように、枠部４１には、第１のリブ部４１５として、集塵電極部４３の接地電極４３１からそれぞれ所定距離だけ離隔した位置に立設されたリブ４１５１およびリブ４１５２と、このリブ４１５２と協働して給電部材４４の導通部４４３を保持する第２のリブ部４１６，４１６とが設けられている。 Further, as shown in FIGS. 10 and 11, ribs 4151 are erected on the frame portion 41 as first rib portions 415 at positions separated from the ground electrode 431 of the dust collecting electrode portion 43 by a predetermined distance. A rib 4152 and a second rib portion 416, 416 for holding the conduction portion 443 of the feeding member 44 in cooperation with the rib 4152 are provided.

第１のリブ部４１５（４１５１，４１５２）は、導通部４４３と平行な方向に対して所定の幅を有する略壁状に形成されている。また、第２のリブ部４１６，４１６は、第１のリブ部４１５のリブ４１５２の両端部に対峙する位置に、それぞれ柱状に形成されている。そして、対峙するリブ４１５２と第２のリブ部４１６との間に、導通部４４３が収容される導通部収容空間４１８が形成される。 The first rib portion 415 (4151, 4152) is formed in a substantially wall shape having a predetermined width in a direction parallel to the conductive portion 443. Further, the second rib portions 416 and 416 are formed in columns at positions facing both ends of the rib 4152 of the first rib portion 415. Then, a conduction portion accommodating space 418 in which the conduction portion 443 is accommodated is formed between the ribs 4152 facing each other and the second rib portion 416.

かかる構成により、図１１および図１２に示すように、給電部材４４の導通部４４３は、第１のリブ部４１５（４１５１，４１５２）によって、異極である接地電極４３１との間の絶縁距離が確保される。すなわち、枠部４１は、導通部配置部４１０が接地電極４３１間の絶縁距離を確保する第１のリブ部４１５を備えることになる。そのため、集塵部４の枠部４１が大型化するのを抑制しつつ、高圧電極４２１に給電する給電部材４４の導通部４４３と、該導通部４４３とは異極である接地電極４３１との空間距離および沿面距離を確保することができる。このように、本実施例に係る電気集塵機２の集塵部４では、集塵部４の大型化を抑制しつつ、互いに異なる極性を有する高圧電極４２１と接地電極４３１との間で短絡することを防止することができる。 With this configuration, as shown in FIGS. 11 and 12, the conduction portion 443 of the feeding member 44 has an insulation distance between the ground electrode 431, which is a different electrode, due to the first rib portion 415 (4151, 4152). It will be secured. That is, the frame portion 41 is provided with the first rib portion 415 in which the conduction portion arranging portion 410 secures the insulation distance between the ground electrodes 431. Therefore, while suppressing the increase in size of the frame portion 41 of the dust collecting portion 4, the conductive portion 443 of the feeding member 44 that supplies power to the high-voltage electrode 421 and the ground electrode 431 that is a different electrode from the conductive portion 443 are used. Spatial distance and creepage distance can be secured. As described above, in the dust collecting unit 4 of the electrostatic precipitator 2 according to the present embodiment, the high voltage electrode 421 and the ground electrode 431 having different polarities are short-circuited while suppressing the increase in size of the dust collecting unit 4. Can be prevented.

また、図１１に示すように、第１のリブ部４１５および第２のリブ部４１６には、給電部材４４の導通部４４３を導通部配置部４１０の底部方向へ案内する案内テーパ４１５ａ，４１６ａが、導通部配置部４１０の開口側にそれぞれ形成されている。したがって、給電部材４４の導通部４４３を、導通部配置部４１０へ容易に案内することができる。 Further, as shown in FIG. 11, the first rib portion 415 and the second rib portion 416 have guide tapers 415a and 416a for guiding the conductive portion 443 of the feeding member 44 toward the bottom of the conductive portion arranging portion 410. , Each is formed on the opening side of the conduction portion arranging portion 410. Therefore, the conductive portion 443 of the feeding member 44 can be easily guided to the conductive portion arranging portion 410.

また、図１１に示すように、第２のリブ部４１６の案内テーパ４１６ａの終端部には、導通部収容空間４１８を形成する底部となる段差部４１６ｂが設けられている。かかる構成により、案内テーパ４１５ａ，４１６ａによって導通部収容空間４１８へ案内される給電部材４４の導通部４４３を受け止めることができる。したがって、導通部４４３を、導通部配置部４１０における所望する位置で保持することができる。 Further, as shown in FIG. 11, a step portion 416b, which is a bottom portion forming the conduction portion accommodating space 418, is provided at the end portion of the guide taper 416a of the second rib portion 416. With such a configuration, it is possible to receive the conductive portion 443 of the feeding member 44 guided to the conductive portion accommodating space 418 by the guide tapers 415a and 416a. Therefore, the conductive portion 443 can be held at a desired position in the conductive portion arranging portion 410.

ところで、図１０～図１２に示すように、枠部４１には、上述してきた第１のリブ部４１５および第２のリブ部４１６の他に、第３のリブ部４１７が形成されている。この第３のリブ部４１７は、給電部材４４の導通部４４３が第１のリブ部４１５よりも接地電極４３１側に配置されるのを防止している。したがって、第３のリブ部４１７の存在により、導通部４４３は、例えば、第１のリブ部４１５であるリブ４１５１，４１５２間に形成された空間４１９に誤って挿通されることがない。そのため、導通部４４３の誤配置によって導通部４４３と接地電極４３１との絶縁距離（空間距離および沿面距離）が確保できなくなってしまうのを防止することができる。 By the way, as shown in FIGS. 10 to 12, a third rib portion 417 is formed in the frame portion 41 in addition to the first rib portion 415 and the second rib portion 416 described above. The third rib portion 417 prevents the conduction portion 443 of the feeding member 44 from being arranged closer to the ground electrode 431 than the first rib portion 415. Therefore, due to the presence of the third rib portion 417, the conductive portion 443 is not erroneously inserted into the space 419 formed between the ribs 4151 and 4152 which are the first rib portions 415, for example. Therefore, it is possible to prevent the insulation distance (space distance and creepage distance) between the conduction portion 443 and the ground electrode 431 from being unable to be secured due to the misalignment of the conduction portion 443.

また、かかる第３のリブ部４１７は、給電部材４４の導通部４４３に対向する面が、第１のリブ部４１５と第２のリブ部４１６との間に形成される導通部収容空間４１８（図１１参照）よりも所定距離だけ接地電極４３１側に位置している。そのため、第３のリブ部４１７は、導通部収容空間４１８に位置する導通部４４３と接触するおそれがない。したがって、導通部４４３が接地電極４３１と近接した位置にある第３のリブ部４１７に接触して短絡するおそれもない。 Further, in the third rib portion 417, the surface of the feeding member 44 facing the conductive portion 443 is formed between the first rib portion 415 and the second rib portion 416, and the conductive portion accommodating space 418 ( It is located closer to the ground electrode 431 by a predetermined distance than (see FIG. 11). Therefore, the third rib portion 417 is unlikely to come into contact with the conductive portion 443 located in the conductive portion accommodating space 418. Therefore, there is no possibility that the conductive portion 443 comes into contact with the third rib portion 417 located close to the ground electrode 431 and short-circuits.
