Description

この発明は、電気集塵ユニット、および電気集塵ユニットを備えた空気清浄装置に関する。 The present invention relates to an electrostatic precipitator and an air purifier including the electrostatic precipitator.

近年、空気中の各種塵埃、粉塵または煙草の煙等を除去するために、塵埃等の粒子をコロナ放電によって荷電し、荷電した粒子を電気的に集塵する電気集塵ユニットが開発されている。このような電気集塵ユニットとしては、家屋内の空気を清浄化したいという要望に伴い、冷暖房装置等の空気調和機に内蔵されたものがある。 In recent years, in order to remove various dusts, dusts, smoke of cigarettes, etc. in the air, an electrostatic dust collecting unit has been developed in which particles such as dusts are charged by corona discharge and the charged particles are electrically collected. .. Such an electrostatic precipitator is built in an air conditioner such as an air conditioner in response to a desire to purify the air in the house.

電気集塵ユニットは、コロナ放電により粒子を荷電する荷電部と、荷電部で荷電粒子となった塵埃を集塵する集塵処理部とから構成されている。このうち集塵処理部は、複数の集塵電極板を有する低圧電極と、複数の非集塵電極板を有する高圧電極とを備え、塵埃の極性と同極性の非集塵電極板に対して反発する塵埃を、塵埃の極性と異極性の集塵電極板に付着させる。 The electrostatic precipitator unit is composed of a charged unit that charges particles by corona discharge and a dust collecting processing unit that collects dust that has become charged particles in the charged unit. Of these, the dust collection processing unit includes a low-pressure electrode having a plurality of dust collection electrode plates and a high-pressure electrode having a plurality of non-dust collection electrode plates, and is provided with respect to the non-dust collection electrode plate having the same polarity as the dust. The repulsive dust is attached to the dust collecting electrode plate having a polarity different from that of the dust.

例えば、空気中の粒子を正極性に帯電させ、非集塵電極板には正極性の高電位を印加すると共に、集塵電極板には接地電位を印加するものが知られている。このような構成を採る場合には、例えば特許文献１のように、非集塵電極板と集塵電極板とを半絶縁性樹脂により形成し、金属製の給電部を非集塵電極板の支持部材に取り付けることが行われている。 For example, it is known that particles in the air are positively charged, a high positive potential is applied to the non-dust collecting electrode plate, and a ground potential is applied to the dust collecting electrode plate. When such a configuration is adopted, for example, as in Patent Document 1, the non-dust collecting electrode plate and the dust collecting electrode plate are formed of a semi-insulating resin, and the metal feeding portion is formed of the non-dust collecting electrode plate. It is attached to a support member.

特開平１１−２０７２０８号公報Japanese Unexamined Patent Publication No. 11-207208

しかしながら、特許文献１のように、給電部を支持部材の外側に露出させた状態で支持部材に取り付ける構成では、電気集塵ユニットを小型化するという要請から、高圧電極と低圧電極とを近づけると、給電部と低圧電極との間で異常放電が発生する問題があった。 However, in the configuration in which the power feeding portion is attached to the support member in a state where it is exposed to the outside of the support member as in Patent Document 1, the high-voltage electrode and the low-voltage electrode are brought closer to each other in order to reduce the size of the electrostatic precipitator unit. , There is a problem that an abnormal discharge occurs between the feeding part and the low voltage electrode.

この発明は、上記の課題を解決するためになされたものであって、低圧電極と、給電部が取り付けられた高圧電極とを近づけて配置する場合であっても、異常放電を発生させることのない電気集塵ユニット、および電気集塵ユニットを備えた空気調和機を提供することを目的とする。 The present invention has been made to solve the above-mentioned problems, and even when the low-voltage electrode and the high-voltage electrode to which the feeding portion is attached are arranged close to each other, an abnormal discharge can be generated. It is an object of the present invention to provide an air conditioner equipped with no electrostatic precipitator and an electrostatic precipitator.

本発明の第１の態様に係る電気集塵ユニットは、貫通孔が形成された係止部を有し、高電圧が印加される高圧電極と、低電圧が印加される低圧電極と、凸部を有し、前記高圧電極に高電圧を供給するための給電部と、高圧電極を係止するための高圧電極係止用爪部を有し、絶縁性材料で形成されたフレーム部と、を備え、給電部は、凸部と係止部の貫通孔との係合により、高圧電極に取り付けられ、フレーム部は、給電部が取り付けられた高圧電極の係止部と、高圧電極係止用爪部とが係合することにより高圧電極を係止し、高圧電極係止用爪部は、貫通孔における前記凸部が位置する側を覆う、ことを特徴とする。 The electrostatic dust collecting unit according to the first aspect of the present invention has a locking portion in which a through hole is formed, and has a high voltage electrode to which a high voltage is applied, a low voltage electrode to which a low voltage is applied, and a convex portion. A feeding portion for supplying a high voltage to the high-voltage electrode, and a frame portion having a high-voltage electrode locking claw portion for locking the high-voltage electrode and made of an insulating material. The feeding portion is attached to the high-voltage electrode by engaging the convex portion and the through hole of the locking portion, and the frame portion is used for locking the high-voltage electrode and the locking portion of the high-voltage electrode to which the feeding portion is attached. The high-voltage electrode is locked by engaging with the claw portion, and the high-voltage electrode locking claw portion covers the side of the through hole where the convex portion is located.

本明細書において、「低電圧」とは、接地電位を含む概念である。 As used herein, the term "low voltage" is a concept that includes a ground potential.

本発明によれば、高圧電極がフレーム部に係止される際、高圧電極係止用爪部は、貫通孔における凸部が位置する側を覆う。したがって、貫通孔に、高電圧を供給する給電部の凸部が係合していても、低電圧が印加される低圧電極と、貫通孔に係合した凸部との間には、絶縁性材料で形成されたフレーム部の高圧電極係止用爪部が存在する。その結果、低圧電極と給電部との間の絶縁性を高めることができ、異常放電を抑制することができる。 According to the present invention, when the high-voltage electrode is locked to the frame portion, the high-voltage electrode locking claw portion covers the side of the through hole where the convex portion is located. Therefore, even if the convex portion of the feeding portion that supplies a high voltage is engaged with the through hole, there is an insulating property between the low voltage electrode to which the low voltage is applied and the convex portion engaged with the through hole. There is a high-voltage electrode locking claw portion of the frame portion made of a material. As a result, the insulating property between the low voltage electrode and the feeding portion can be improved, and abnormal discharge can be suppressed.

Attach to. Further, the low voltage terminal 9 is attached to the low voltage terminal mounting portion 20 of the edge portion 7f. Next, one end of the spring 8A is attached to one end of the discharge electrode 3, and then one end of the spring 8B is attached to the other end of the discharge electrode 3. After that, the other end of the spring 8A is engaged with the claw portion 11a of the charged high-voltage terminal 11, the discharge electrode 3 is folded back at the support portion 14, and the discharge electrode 3 is further folded back at the support portion 12.

図７は、カバー２をフレーム部７に取り付ける前の状態の電気集塵ユニット１の内部を示す平面図である。図７に示すように、集塵部４の荷電部低圧電極板４０と放電電極３とが対向している。放電電極３には、荷電高圧端子１１を介して高圧の電位が供給され、荷電部低圧電極板４０には、低圧端子９を介して低圧電位として接地電位が供給される。その結果、放電電極３と荷電部低圧電極板４０とによりコロナ放電が発生し、このコロナ放電によって空気中の微粒子に電荷を与える機能を果たす。このように本実施形態においては、集塵部４の荷電部低圧電極板４０と放電電極３との対向領域が、荷電部３５として働く。 FIG. 7 is a plan view showing the inside of the electrostatic precipitator unit 1 in a state before the cover 2 is attached to the frame portion 7. As shown in FIG. 7, the low-voltage electrode plate 40 of the charged portion of the dust collecting portion 4 and the discharging electrode 3 face each other. A high-voltage potential is supplied to the discharge electrode 3 via the charged high-voltage terminal 11, and a ground potential is supplied as a low-voltage potential to the charged portion low-voltage electrode plate 40 via the low-voltage terminal 9. As a result, a corona discharge is generated by the discharge electrode 3 and the low-voltage electrode plate 40 of the charged portion, and the corona discharge functions to give a charge to the fine particles in the air. As described above, in the present embodiment, the opposite region between the low-voltage electrode plate 40 of the charged portion of the dust collecting portion 4 and the discharge electrode 3 acts as the charged portion 35.

荷電部３５の下方においては、集塵部４の集塵部低圧電極４１と、集塵部高圧電極５０とが対向している。上述したように、集塵部低圧電極４１には接地電位が供給され、集塵部高圧電極５０には高圧の電位が供給される。したがって、荷電部３５において正の電荷を与えられた空気中の微粒子は、高圧の電位の集塵部高圧電極５０に反発し、接地電位の集塵部低圧電極４１に付着することになる。このようにして、集塵が行われる。 Below the charged portion 35, the dust collecting portion low-voltage electrode 41 of the dust collecting portion 4 and the dust collecting portion high-voltage electrode 50 face each other. As described above, the ground potential is supplied to the dust collecting part low voltage electrode 41, and the high voltage potential is supplied to the dust collecting part high voltage electrode 50. Therefore, the fine particles in the air given a positive charge in the charged portion 35 repel the high-voltage electrode 50 of the dust collecting portion having a high potential and adhere to the low-voltage electrode 41 of the dust collecting portion having a ground potential. In this way, dust collection is performed.

次に、本実施形態における係止部５１ｃと、フレーム部７の高圧電極係止用爪部７ｉとの位置関係について説明する。以下の説明では、高圧電極係止用爪部７ｉを単に爪部７ｉと称する。図８は、枠部５１に給電部６を取り付けた状態における係止部５１ｃの周辺を示す部分拡大平面図である。図９は、図８に対応する部分拡大底面図である。図１０は、図６における右側の長辺部７ａに形成された爪部７ｉの周辺を示す部分斜視図である。図１１は、図６における左側の長辺部７ａに形成された爪部７ｉの周辺を示す部分斜視図である。 Next, the positional relationship between the locking portion 51c in the present embodiment and the high-pressure electrode locking claw portion 7i of the frame portion 7 will be described. In the following description, the high-voltage electrode locking claw portion 7i is simply referred to as a claw portion 7i. FIG. 8 is a partially enlarged plan view showing the periphery of the locking portion 51c in a state where the feeding portion 6 is attached to the frame portion 51. FIG. 9 is a partially enlarged bottom view corresponding to FIG. FIG. 10 is a partial perspective view showing the periphery of the claw portion 7i formed on the long side portion 7a on the right side in FIG. FIG. 11 is a partial perspective view showing the periphery of the claw portion 7i formed on the long side portion 7a on the left side in FIG.

図９に示すように、集塵部高圧電極５０および枠部５１のＹ方向における底面側から、給電部６の凸部６ｃを係止部５１ｃの貫通孔５１ｄに圧入すると、図８に示すように、集塵部高圧電極５０および枠部５１のＹ方向における上面側から見ると、給電部６の凸部６ｃが貫通孔５１ｄから目視することができる状態となる。しかしながら、係止部５１ｃの上面側の端面５１ｅは、集塵部高圧電極５０および枠部５１をフレーム部７に取り付けた状態においては、以下のような爪部７ｉによって覆われる。 As shown in FIG. 9, when the convex portion 6c of the feeding portion 6 is press-fitted into the through hole 51d of the locking portion 51c from the bottom surface side of the dust collecting portion high-voltage electrode 50 and the frame portion 51 in the Y direction, as shown in FIG. When viewed from the upper surface side of the dust collecting portion high-voltage electrode 50 and the frame portion 51 in the Y direction, the convex portion 6c of the feeding portion 6 can be visually recognized from the through hole 51d. However, the end surface 51e on the upper surface side of the locking portion 51c is covered with the following claw portion 7i in a state where the dust collecting portion high-voltage electrode 50 and the frame portion 51 are attached to the frame portion 7.

図１０に示すように、図６における右側の長辺部７ａに形成された爪部７ｉは、長辺部７ａに連続する支持部７ｉ１と、支持部７ｉ１に連続し、矢印Ｚ方向に突出して形成された庇部７ｉ２とを備えている。この爪部７ｉは、側板７ｄとは独立に形成されており、弾性変形により、矢印Ｐ方向に揺動可能に形成されている。 As shown in FIG. 10, the claw portion 7i formed on the long side portion 7a on the right side in FIG. 6 is continuous with the support portion 7i1 continuous with the long side portion 7a and the support portion 7i1 and protrudes in the arrow Z direction. It is provided with a formed eaves portion 7i2. The claw portion 7i is formed independently of the side plate 7d, and is formed so as to be swingable in the arrow P direction due to elastic deformation.

図１１に示すように、図６における左側の長辺部７ａに形成された爪部７ｉは、図１０に示す爪部７ｉの庇部７ｉ２に対応する部位が、側板７ｄに連続して形成されている。 As shown in FIG. 11, in the claw portion 7i formed on the left long side portion 7a in FIG. 6, a portion corresponding to the eaves portion 7i2 of the claw portion 7i shown in FIG. 10 is continuously formed on the side plate 7d. ing.

以上のような爪部７ｉが形成されたフレーム部７に、給電部６が取り付けられた集塵部高圧電極５０および枠部５１を取り付ける場合には、まず、図６における左側の長辺部７ａに形成された爪部７ｉと、係止部５１ｃとを仮に係合させる。次に、集塵部高圧電極５０および枠部５１をフレーム部７に載置することにより、枠部５１が、図６における左側の長辺部７ａに形成された爪部７ｉにおける庇部７ｉ２の斜面７ｉ２−１と当接しながら爪部７ｉを押下する。その結果、爪部７ｉは弾性変形により図１０に示す矢印Ｐ方向に揺動して広がり、枠部５１が、フレーム部７の長辺部７ａに当接したところで、爪部７ｉは弾性変形により矢印Ｐ方向とは逆方向に戻る。そして、係止部５１ｃと爪部７ｉとが係合することになる。また、この状態において、図６における左側の長辺部７ａに形成された爪部７ｉと、係止部５１ｃとは、確実な係合状態となる。 When attaching the dust collecting portion high-voltage electrode 50 and the frame portion 51 to which the feeding portion 6 is attached to the frame portion 7 on which the claw portion 7i is formed as described above, first, the long side portion 7a on the left side in FIG. The claw portion 7i formed in the above and the locking portion 51c are tentatively engaged with each other. Next, by placing the dust collecting portion high-voltage electrode 50 and the frame portion 51 on the frame portion 7, the frame portion 51 is formed on the left long side portion 7a in FIG. The claw portion 7i is pressed while contacting the slope 7i2-1. As a result, the claw portion 7i swings and spreads in the direction of the arrow P shown in FIG. 10 due to elastic deformation, and when the frame portion 51 abuts on the long side portion 7a of the frame portion 7, the claw portion 7i is elastically deformed. It returns in the direction opposite to the arrow P direction. Then, the locking portion 51c and the claw portion 7i are engaged with each other. Further, in this state, the claw portion 7i formed on the long side portion 7a on the left side in FIG. 6 and the locking portion 51c are in a reliable engaging state.

図１２は、給電部６を取り付けた集塵部高圧電極５０および枠部５１をフレーム部７に取り付けた状態を示す平面図である。図１２に示すように、集塵部高圧電極５０および枠部５１をフレーム部７に取り付けると、係止部５１ｃの端面５１ｅは、フレーム部７の爪部７ｉによって覆われ、図１２に示す平面視においては、係止部５１ｃの貫通孔５１ｄは見えない状態となる。 FIG. 12 is a plan view showing a state in which the dust collecting portion high-voltage electrode 50 and the frame portion 51 to which the feeding portion 6 is attached are attached to the frame portion 7. As shown in FIG. 12, when the dust collecting portion high-voltage electrode 50 and the frame portion 51 are attached to the frame portion 7, the end surface 51e of the locking portion 51c is covered by the claw portion 7i of the frame portion 7, and the plane shown in FIG. Visually, the through hole 51d of the locking portion 51c is invisible.

図１３は、フレーム部７に取り付ける前の状態の係止部５１ｃの周辺を示す部分拡大斜視図である。図１４は、フレーム部７に取り付けた後の状態の係止部５１ｃの周辺を示す部分拡大斜視図である。図１３と図１４とを比較するとよく分かるように、フレーム部７に集塵部高圧電極５０および枠部５１を取り付けた状態においては、係止部５１ｃの上面側、つまり集塵部４側の端面５１ｅは、爪部７ｉの庇部７ｉ２によって覆われる。したがって、図８に示すように係止部５１ｃの貫通孔５１ｄに圧入された給電部６の凸部６ｃも、爪部７ｉによって覆われることになる。 FIG. 13 is a partially enlarged perspective view showing the periphery of the locking portion 51c in a state before being attached to the frame portion 7. FIG. 14 is a partially enlarged perspective view showing the periphery of the locking portion 51c in a state after being attached to the frame portion 7. As can be clearly seen by comparing FIGS. 13 and 14, when the dust collecting portion high voltage electrode 50 and the frame portion 51 are attached to the frame portion 7, the upper surface side of the locking portion 51c, that is, the dust collecting portion 4 side. The end face 51e is covered with the eaves portion 7i2 of the claw portion 7i. Therefore, as shown in FIG. 8, the convex portion 6c of the feeding portion 6 press-fitted into the through hole 51d of the locking portion 51c is also covered by the claw portion 7i.

以上のように、フレーム部７の爪部７ｉは、係止部５１ｃと係合する係合部として働くと共に、係止部５１ｃの矢印Ｙ方向における上側の端面５１ｅを覆うカバー部として働くことになる。その結果、集塵部高圧電極５０および枠部５１の上から集塵部４をフレーム部７に取り付けても、高圧の電位が供給される凸部６ｃと、接地電位が印加される集塵部４との間の絶縁性を確保することができる。したがって、本発明によれば、異常放電の発生を抑制することができる。 As described above, the claw portion 7i of the frame portion 7 acts as an engaging portion that engages with the locking portion 51c, and also acts as a cover portion that covers the upper end surface 51e of the locking portion 51c in the arrow Y direction. Become. As a result, even if the dust collecting portion 4 is attached to the frame portion 7 from above the dust collecting portion high voltage electrode 50 and the frame portion 51, the convex portion 6c to which the high voltage potential is supplied and the dust collecting portion to which the ground potential is applied. Insulation between 4 and 4 can be ensured. Therefore, according to the present invention, the occurrence of abnormal discharge can be suppressed.

また、給電部６を取り付けた集塵部高圧電極５０および枠部５１と、集塵部４とを近づけて取り付けることができ、給電部６と集塵部４との空間距離を小さくすることができる。したがって、電気集塵ユニット１を小型化することができる。 Further, the dust collecting section high-voltage electrode 50 and the frame section 51 to which the feeding section 6 is attached can be mounted close to each other, and the space distance between the feeding section 6 and the dust collecting section 4 can be reduced. it can. Therefore, the electrostatic precipitator unit 1 can be miniaturized.

また、給電部６の凸部６ｃを貫通孔５１ｄに圧入することにより、給電部６を集塵部高圧電極５０および枠部５１に確実に固定することができる。給電部６は枠部５１と確実に接触するため、高電圧を効率よく供給することが可能となる。 Further, by press-fitting the convex portion 6c of the feeding portion 6 into the through hole 51d, the feeding portion 6 can be reliably fixed to the dust collecting portion high-voltage electrode 50 and the frame portion 51. Since the power feeding unit 6 is in reliable contact with the frame unit 51, it is possible to efficiently supply a high voltage.

以上のように、本発明の電気集塵ユニット１によれば、給電部６の凸部６ｃが圧入された係止部５１ｃに、フレーム部７の爪部７ｉを係合させると共に、係止部５１ｃの端面５１ｅを爪部７ｉにより覆うので、異常放電の発生を抑えることができる。 As described above, according to the electrostatic precipitator unit 1 of the present invention, the claw portion 7i of the frame portion 7 is engaged with the locking portion 51c into which the convex portion 6c of the feeding portion 6 is press-fitted, and the locking portion is engaged. Since the end face 51e of the 51c is covered with the claw portion 7i, the occurrence of abnormal discharge can be suppressed.
