静電霧化装置は、電圧が印加されることにより一面が吸熱し、他面が発熱するペルチェ素子の一面に放電電極が結合され、ペルチェ素子の他面に、放熱フィンを有する放熱板が結合され、電圧がペルチェ素子に印加されることにより放電電極を冷却し、空気中の水分を放電電極の先端部に結露させ、電圧が放電電極に印加されることにより該放電電極の先端部に静電霧化現象を発生させ、負極性の帯電微粒子水を発生させるように構成されている(例えば、特許文献1参照)。   In the electrostatic atomizer, one side absorbs heat when voltage is applied, the other side generates heat, the discharge electrode is connected to one side, and the other side of the Peltier element is connected to a heat sink with heat dissipation fins.

ところで、ペルチェ素子、放電電極及び放熱板を有する静電霧化装置において、複数の放電電極を離隔して配し、放電電極夫々が負極性の帯電微粒子水を発生することにより、空気中の負極性の帯電微粒子水の量を多くすることが考えられる。   By the way, in an electrostatic atomizer having a Peltier element, a discharge electrode, and a heat sink, a plurality of discharge electrodes are arranged apart from each other, and each discharge electrode generates negative charged fine particle water. It is conceivable to increase the amount of the electrically charged fine particle water.

しかし、複数の放電電極を備える場合、放電電極の個数が増えるだけでなく、放電電極が結合されるペルチェ素子、及び放電電極に結合される放熱板の個数も増え、放電電極、ペルチェ素子及び放熱板を有するユニットの複数が離隔して配されることになるため、ユニットの設置スペースが広くなり、コストも高くなる。   However, when a plurality of discharge electrodes are provided, not only the number of discharge electrodes is increased, but also the number of Peltier elements to which the discharge electrodes are coupled and the number of heat radiation plates coupled to the discharge electrodes are increased. Since a plurality of units having plates are arranged apart from each other, the space for installing the units is widened and the cost is increased.

本発明は斯かる事情に鑑みてなされたものであり、主たる目的は、一面に複数の放熱凸部を有する放熱板の他面に、ペルチェ素子が対接している複数の放電電極を配することにより、複数の放電電極を比較的狭い設置スペースに設置することができ、比較的小型にすることができるとともに、コストを低減することができる静電霧化装置を提供することにある。   The present invention has been made in view of such circumstances, and a main object thereof is to arrange a plurality of discharge electrodes in contact with Peltier elements on the other surface of a heat radiating plate having a plurality of heat radiating protrusions on one surface. Accordingly, it is an object of the present invention to provide an electrostatic atomizer that can install a plurality of discharge electrodes in a relatively narrow installation space, can be made relatively small, and can reduce costs.

本発明に係る静電霧化装置は、放電により帯電微粒子水が発生する放電電極と、その吸熱側の面が前記放電電極と対接するペルチェ素子と、該ペルチェ素子の放熱側の面が熱接触する放熱板とを有する静電霧化装置において、前記放熱板は、一面に複数の放熱凸部を有しており、前記放熱板の他面に、前記ペルチェ素子が対接している複数の放電電極を離隔して配してあることを特徴とする。   The electrostatic atomizer according to the present invention includes a discharge electrode that generates charged fine particle water by discharge, a Peltier element whose heat absorption side surface is in contact with the discharge electrode, and a heat dissipation side surface of the Peltier element that is in thermal contact. In the electrostatic atomizer having a heat radiating plate, the heat radiating plate has a plurality of heat radiating projections on one surface, and a plurality of discharges in which the Peltier element is in contact with the other surface of the heat radiating plate. The electrodes are spaced apart from each other.

この発明にあっては、一面に複数の放熱凸部を有する放熱板の他面に複数の放電電極を配してあり、放熱板と複数の放電電極及びペルチェ素子とがユニットになっているため、複数の放電電極を比較的狭い設置スペースに設置することができ、比較的小型にすることができるとともに、コストを低減することができる。また、離隔する放電電極の間に放熱板があるため、放電電極夫々の周りに結露する場合であっても、放電電極の間の結露を放熱板にて防ぐことができ、極性が異なる放電電極間の絶縁を確保することができる。   In the present invention, a plurality of discharge electrodes are arranged on the other surface of the heat radiating plate having a plurality of heat radiating protrusions on one surface, and the heat radiating plate, the plurality of discharge electrodes and the Peltier element are united. The plurality of discharge electrodes can be installed in a relatively small installation space, and can be made relatively small, and the cost can be reduced. In addition, since there is a heat sink between the discharge electrodes that are separated from each other, even if condensation occurs around each of the discharge electrodes, condensation between the discharge electrodes can be prevented by the heat sink and the discharge electrodes have different polarities. Insulation between them can be ensured.

Further, since the heat of the heat radiating plate is transmitted to the protrusion and the protrusion is heated, the temperature of the air around the discharge electrode can be increased. In particular, at a low temperature (for example, 5 ° C. or less), the discharge electrode is cooled while heating the air around the discharge electrode, thereby preventing the temperature of the discharge electrode and the air from being frozen. A difference can be generated to condense the discharge electrode, and the amount of charged fine particle water generated can be increased.

また、本発明に係る静電霧化装置は、前記放熱板の他面は、前記放電電極夫々の間に、前記放電電極が離隔する方向と交差する方向に伸びる溝を設けてある構成とするのが好ましい。
この発明にあっては、隣合う放電電極間における放熱板の表面積を多くすることができ、当該部分の放熱性を高めることができるため、放電電極の放熱板側が結露することがあっても、当該部分の結露を速やかに蒸発させることが可能であり、また、隣合う放電電極間で熱を移動させ難くすることができ、各放電電極側の熱を放熱板から放熱することができる。
Moreover, the electrostatic atomizer which concerns on this invention is set as the structure by which the other surface of the said heat sink has provided the groove | channel extended in the direction which cross | intersects the direction which the said discharge electrode separates between each of the said discharge electrodes. Is preferred.
In this invention, since the surface area of the heat sink between adjacent discharge electrodes can be increased and the heat dissipation of the part can be increased, even if the heat sink side of the discharge electrode may condense, It is possible to quickly evaporate the condensation of the portion, and it is possible to make it difficult to transfer heat between adjacent discharge electrodes, and it is possible to dissipate heat on the side of each discharge electrode from the heat radiating plate.

また、本発明に係る静電霧化装置は、前記突起は、前記放電電極の少なくとも一方の周りを取り囲む筒形をなしている構成とするのが好ましい。
この発明にあっては、隣合う放電電極間を筒形の突起にて遮蔽することができるので、隣合う放電電極の極性が異なる場合においても、隣合う放電電極間で正極性の帯電微粒子水と負極性の帯電微粒子水とが再結合するのを防ぐことができる。
In the electrostatic atomizer according to the present invention, it is preferable that the protrusion has a cylindrical shape surrounding at least one of the discharge electrodes.
In the present invention, since the adjacent discharge electrodes can be shielded by the cylindrical protrusion, even when the polarities of the adjacent discharge electrodes are different, the positive charged fine particle water between the adjacent discharge electrodes. And negatively charged charged fine particle water can be prevented from recombining.

また、本発明に係る静電霧化装置は、前記ペルチェ素子は、前記放電電極夫々に亘って一体に形成してある構成とするのが好ましい。
この発明にあっては、複数の放電電極に対して放熱板及びペルチェ素子の夫々が一つであり、部品点数を低減できるので、コストをより一層低減できる。
In the electrostatic atomizer according to the present invention, it is preferable that the Peltier element is formed integrally with each of the discharge electrodes.
In this invention, since each of the heat sink and the Peltier element is one for the plurality of discharge electrodes, the number of parts can be reduced, so that the cost can be further reduced.

また、本発明に係る静電霧化装置は、前記ペルチェ素子は、前記放電電極夫々の間に絶縁突起を設けてある構成とするのが好ましい。
この発明にあっては、離隔する放電電極の間に絶縁突起があるため、放電電極間の離隔寸法を短くし、小型化を図った場合においても、放電電極間の沿面距離を確保することができ、極性が異なる放電電極間の絶縁を確保することができる。また、絶縁突起はペルチェ素子にて吸熱されにくいため、絶縁突起周りの結露を抑制することができる。

It is possible to ensure insulation between the discharge electrodes having different polarities. In addition, since the insulating protrusion is less likely to absorb heat by the Peltier element, it is possible to suppress condensation around the insulating protrusion.

本発明によれば、一面に複数の放熱凸部を有する放熱板の他面に複数の放電電極を配してあり、放熱板と複数の放電電極及びペルチェ素子とがユニットになっているため、複数の放電電極を比較的狭い設置スペースに設置することができ、比較的小型にすることができるとともに、コストを低減することができる。また、離隔する放電電極の間に放熱板があるため、放電電極夫々の周りに結露する場合であっても、放電電極の間の結露を放熱板にて防ぐことができ、放電電極間の絶縁を確保することができる。   According to the present invention, a plurality of discharge electrodes are arranged on the other surface of the heat radiating plate having a plurality of heat radiating protrusions on one surface, and the heat radiating plate and the plurality of discharge electrodes and Peltier elements are united. A plurality of discharge electrodes can be installed in a relatively narrow installation space, and can be made relatively small and the cost can be reduced. In addition, since there is a heat dissipation plate between the discharge electrodes that are separated from each other, even if condensation occurs around each discharge electrode, condensation between the discharge electrodes can be prevented by the heat dissipation plate, and insulation between the discharge electrodes can be prevented. Can be secured.

また、本発明によれば、離隔する放電電極の間に突起があるため、放電電極間の離隔寸法を短くし、小型化を図った場合においても、放電電極間の沿面距離を確保することができ、放電電極間の絶縁を確保することができる。また、放熱板の熱が突起に伝達され、突起が加熱されるため、放電電極周りの空気の温度を高めることができ、放電電極が結露し易くなり、帯電微粒子水の発生量を多くすることができるとともに、放電電極に結露させるために必要な消費電力を低減できる。   In addition, according to the present invention, since there is a protrusion between the discharge electrodes that are spaced apart from each other, even when the separation distance between the discharge electrodes is shortened and the size is reduced, the creeping distance between the discharge electrodes can be secured.
