第３の発明は、放電電極、前記放電電極の対向に配置された対向電極、これらの電極間に高電圧を印加して放電させる高電圧印加手段、放熱面と冷却面とを有するペルチェ素子を有し、前記冷却面を前記放電電極に密着して設け、前記ペルチェ素子により前記放電電極を露点以下の温度にして前記放電電極の表面に結露水を発生させるとともに、前記高電圧印加手段によって前記放電電極と前記対向電極との間に高電圧を印加するように構成した浄化装置を搭載した室内機を備え、前記室内機は、室内温度を検出する室内温度検出手段、室内湿度を検出する室内湿度検出手段、吹出気流の温度を間接的または直接的に検出する吹出温度検出手段を有し、前記各検出手段によって検出された室内温度と室内湿度の情報に基づいて判断される室内の絶対湿度と前記吹出温度検出手段によって検出された吹出気流の温度とに応じて、前記ペルチェ素子の出力と前記高電圧印加手段の出力とを制御するもので、前記吹出気流の温度が前記放電電極に水が結露しないと判断される所定値を超えた場合には、前記ペルチェ素子の出力と前記高電圧印加手段の出力とを停止するように制御することを特徴とする空気調和機である。 According to a third aspect of the present invention, there is provided a Peltier element having a discharge electrode, a counter electrode disposed opposite to the discharge electrode, high voltage applying means for applying a high voltage between these electrodes to discharge, and a heat radiating surface and a cooling surface. The cooling surface is provided in close contact with the discharge electrode, and the Peltier element causes the discharge electrode to have a temperature below the dew point to generate dew condensation water on the surface of the discharge electrode, and the high voltage application means An indoor unit equipped with a purifier configured to apply a high voltage between a discharge electrode and the counter electrode is provided, the indoor unit detecting indoor temperature, indoor temperature detecting means for detecting indoor temperature, and indoor for detecting indoor humidity A room having humidity detection means and blowout temperature detection means for indirectly or directly detecting the temperature of the blown airflow, and is judged based on information on the room temperature and the room humidity detected by each of the detection means The absolute humidity and depending on the temperature of the outlet temperature detection blowing airflow is detected by the means, the output of the Peltier element and the output of the high voltage applying means braking intended to control the temperature of the outlet air flow the discharge An air conditioner that controls to stop the output of the Peltier element and the output of the high voltage applying means when a predetermined value determined that water does not condense on the electrode is exceeded. .

これにより、吹出温度を間接的に検出する配管温度や直接的に検出する吹出気流の温度が、第１の所定値より高い場合は、浄化装置周辺を流れる空気の温度上昇により電極表面の温度が露点温度以下に下がらず電極への水の結露が生じないと判断し、水発生手段や高電圧印可手段への不必要な通電を停止し、より効率的な運転を行うことができるとともに、電極に水が無い状態で放電することによる電極の劣化も防止することができる。さらに、浄化装置周辺を流れる吹出気流の温度上昇によるペルチェ素子への過剰な熱負荷を防ぎ、ペルチェ素子の寿命の低下を防ぐことができる。 Thereby, when the temperature of the pipe that indirectly detects the blowing temperature or the temperature of the blowing airflow that is directly detected is higher than the first predetermined value, the temperature of the electrode surface is increased by the temperature rise of the air flowing around the purifier. It is judged that the dew point temperature does not drop and the condensation of water on the electrode does not occur, and unnecessary energization to the water generating means and high voltage applying means is stopped, so that more efficient operation can be performed. It is also possible to prevent the electrode from being deteriorated due to the discharge in the absence of water. Furthermore, it is possible to prevent an excessive heat load on the Peltier element due to the temperature rise of the blown airflow flowing around the purifier, and to prevent a decrease in the life of the Peltier element.

また、吹出気流の温度が第２の所定値より低い場合は、浄化装置周辺を流れる空気の温度低下により電極表面の温度が氷点下になり電極表面で水が氷結したと判断し、水発生手段や高電圧印可手段への不必要な通電を停止することができるとともに、氷結を溶けて水に戻った後再度正常な放電が可能となり、電極からラジカルやイオン等を含んだ微細な水粒子を持続して放出することができる。 Further , when the temperature of the blown airflow is lower than the second predetermined value, it is determined that the temperature of the electrode surface is below the freezing point due to the temperature drop of the air flowing around the purification device, and water is frozen on the electrode surface. Unnecessary energization to the high-voltage application means can be stopped, and normal discharge can be performed again after melting the ice and returning to the water, and fine water particles containing radicals and ions are sustained from the electrode. Can be released.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の
形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

（実施の形態１）
図１は、本発明の第１の実施の形態における浄化装置の構成図を示す一例である。浄化ユニット１は、気体の流路内に配置されるものであり、放電電極２が配置され、放電電極２の対向に対向電極３が配置されていて、放電電極２と対向電極３との間に放電領域が形成される。４は浄化ユニット１に流れ込む上流側気流、５は浄化ユニット１の下流側気流を示す。 (Embodiment 1)
FIG. 1 is an example showing a configuration diagram of a purification device according to a first embodiment of the present invention. The purification unit 1 is arranged in a gas flow path, a discharge electrode 2 is arranged, a counter electrode 3 is arranged opposite to the discharge electrode 2, and between the discharge electrode 2 and the counter electrode 3. A discharge region is formed. 4 indicates the upstream airflow flowing into the purification unit 1, and 5 indicates the downstream airflow of the purification unit 1.

高電圧印加手段６は、放電電極２に接続する電極（プラスまたはマイナス）と、対向電極３に接続するアース電極とを有し、放電電極２と対向電極３との間に、放電を発生させ得る高電圧を印加するように構成されている。この高電圧印加手段６としては、高圧トランスで昇圧するようにした電装回路などが使用される。しかし所望の高電圧を印加できるものであれば、これに限定されず使用可能である。   The high voltage applying means 6 has an electrode (plus or minus) connected to the discharge electrode 2 and a ground electrode connected to the counter electrode 3, and generates a discharge between the discharge electrode 2 and the counter electrode 3. It is configured to apply a high voltage to be obtained. As the high voltage applying means 6, an electrical circuit or the like that is boosted by a high voltage transformer is used. However, any device capable of applying a desired high voltage can be used without being limited to this.

水発生手段７は、例えばペルチェ素子など無給水で水を発生させるのもであり、冷却面側に放電電極２に密着させ設ける。これにより、放電電極２が露点以下の温度になると放電電極２の表面に結露水が発生する。例えば、温度が２２℃で湿度が３０％のとき、放電電極２が露点すなわち３．６℃以下の温度になると放電電極２の表面に結露水が発生する。放電電極２に水が結露した状態において、高電圧印加手段６によって高電圧が印可されると、放電電極２の尖端から静電霧化（静電気力によって電極尖端から水が霧化してミストを放出する現象）が生じ、ラジカルやイオン等、およびそれらを含んだ微細な水粒子が対向電極３に向かって放出される。放出された微細な水粒子は、浄化ユニット１に流れ込む気流によって、浄化対象空間に放出される。   The water generating means 7 generates water without supplying water, such as a Peltier element, and is provided in close contact with the discharge electrode 2 on the cooling surface side. Thereby, when the discharge electrode 2 becomes a temperature below the dew point, condensed water is generated on the surface of the discharge electrode 2. For example, when the temperature is 22 ° C. and the humidity is 30%, condensed water is generated on the surface of the discharge electrode 2 when the discharge electrode 2 reaches a dew point, that is, a temperature of 3.6 ° C. or lower. When high voltage is applied by the high voltage applying means 6 in a state where water is condensed on the discharge electrode 2, electrostatic atomization is generated from the tip of the discharge electrode 2 (water is atomized from the electrode tip by electrostatic force to release mist. Phenomenon), radicals, ions, and the like, and fine water particles containing them are emitted toward the counter electrode 3. The discharged fine water particles are discharged into the purification target space by the airflow flowing into the purification unit 1.

このように、ペルチェ素子を利用することによって、電極から発生するラジカルやイオン等、およびそれらを含んだ微細な水粒子の生成のために必要な水を無給水で供給することができ、居住者がタンクに給水する手間を要することなく浄化効果を得ることができる。   In this way, by using the Peltier element, radicals and ions generated from the electrodes and the water necessary for generating fine water particles containing them can be supplied without supply of water. The purification effect can be obtained without the need for supplying water to the tank.

また、放熱促進手段８は、例えばヒートシンクなどの放熱促進材であり、ペルチェ素子等の水発生手段７の放熱面に密着して設けられ、ペルチェ素子の放熱を促進し、電極の冷却効果を高めるものである。   The heat radiation promoting means 8 is a heat radiation promoting material such as a heat sink, for example, and is provided in close contact with the heat radiation surface of the water generating means 7 such as a Peltier element to promote heat radiation of the Peltier element and enhance the cooling effect of the electrodes. Is.

９は浄化ユニット１に流れ込む上流側気流４の温度を検出する、つまり、浄化ユニット１が設置された室内空気の温度を検出する室内温度検出手段、１０は同じく室内空気の湿度を検出する室内湿度検出手段であり、検出された室内空気の温度、湿度に応じて、水発生手段７や高電圧印可手段６の出力を制御するために設けている。   Reference numeral 9 indicates the temperature of the upstream airflow 4 flowing into the purification unit 1, that is, indoor temperature detection means for detecting the temperature of the indoor air in which the purification unit 1 is installed, and 10 indicates the indoor humidity that also detects the humidity of the indoor air. It is a detecting means, and is provided for controlling the output of the water generating means 7 and the high voltage applying means 6 according to the detected temperature and humidity of the indoor air.

図２は、本発明の第１の実施の形態における浄化装置が設けられた空気調和機の室内機の構成図を示す一例である。図２において、浄化ユニット１は、室内機１１の吹出気流１２が流れる風路側に設けられている。また、室内温度検出手段９および室内湿度検出手段１０は、室内機の吸込気流１３が流れる風路内の熱交換器１４の上流側に設けられており、室内空気の温度、湿度が検出できるようになっている。   FIG. 2 is an example showing a configuration diagram of an indoor unit of an air conditioner provided with the purification device according to the first embodiment of the present invention. In FIG. 2, the purification unit 1 is provided on the air path side through which the blown air flow 12 of the indoor unit 11 flows. Moreover, the indoor temperature detection means 9 and the indoor humidity detection means 10 are provided on the upstream side of the heat exchanger 14 in the air passage through which the intake airflow 13 of the indoor unit flows, so that the temperature and humidity of the indoor air can be detected. It has become.

また、熱交換器１３には、配管温度を検出する配管温度検出手段１５を設け、ほぼ吹出気流の温度（吹出温度）に相当する温度が検出できるようになっており、検出された吹出温度に応じて、水発生手段７や高電圧印可手段６の出力を制御するために設けている。また、風量の大きい室内機の送風機１６は、浄化ユニット１の電極から発生するラジカルやイオン等、およびそれらを含んだ微細な水粒子を吹出気流にとともに室内に広範囲に放出
することができ、室内の浄化性能を向上することができる。また、浄化ユニット１の放熱促進手段８に吹出気流が通風することで放熱が促進され、電極の冷却効果を高めることができるため、ペルチェ素子への通電量を少なくして電極に必要な水を供給することができる。なお、本実施の形態においては、吹出温度を配管温度検出手段１５により、間接的に検出しているが、吹出温度を直接検出するよう温度センサを設けてもよい。 Further, the heat exchanger 13 is provided with a pipe temperature detecting means 15 for detecting the pipe temperature so that a temperature substantially corresponding to the temperature of the blown airflow (blowout temperature) can be detected. Accordingly, it is provided to control the output of the water generating means 7 and the high voltage applying means 6. Moreover, the blower 16 of the indoor unit with a large air volume can discharge radicals, ions, and the like generated from the electrodes of the purification unit 1 and fine water particles containing them into the indoor air in a wide range together with the blown airflow. The purification performance of can be improved. In addition, since the blown airflow is passed through the heat dissipation promotion means 8 of the purification unit 1, heat dissipation is promoted, and the cooling effect of the electrode can be enhanced. Therefore, the amount of current supplied to the Peltier element can be reduced and water necessary for the electrode can be reduced. Can be supplied. In the present embodiment, the blowing temperature is indirectly detected by the pipe temperature detecting means 15, but a temperature sensor may be provided so as to directly detect the blowing temperature.

図３は、本発明の第１の実施の形態における浄化装置およびその制御方法の制御ブロック図を示すものである。図３において、１７は、送風機１６の運転に関する情報、つまり送風機１６の回転数や風量を出力する送風機運転情報出力手段である。１８は、室内温度検出手段９、室内湿度検出手段１０、配管温度検出手段１５、送風機運転情報出力手段１７の各情報を基に、水発生手段７や高電圧印可手段６の出力を制御する浄化装置制御手段である。   FIG. 3 is a control block diagram of the purification device and the control method thereof according to the first embodiment of the present invention. In FIG. 3, reference numeral 17 denotes blower operation information output means for outputting information related to the operation of the blower 16, that is, the rotational speed and air volume of the blower 16. 18 is a purification that controls the output of the water generating means 7 and the high voltage applying means 6 based on the information of the indoor temperature detecting means 9, the indoor humidity detecting means 10, the pipe temperature detecting means 15, and the blower operation information output means 17. Device control means.

図４は、室内温度と室内湿度の情報を基に判断される室内の絶対湿度と配管温度に応じて決定される水発生手段７の運転のＯＮ時間とＯＦＦ時間の組み合わせの設定値を示す一例である。例えば、水発生手段７の出力は、所定のＯＮ時間と所定のＯＦＦ時間でＯＮ／ＯＦＦを繰り返すとともに、ＯＮ時間とＯＦＦ時間の組み合わせを変化させることで出力時間を調節、つまり、電極の冷却度合いを調節できるようになっている。なお、水発生手段７の出力は、ＯＮ／ＯＦＦ時間を変化させるだけでなく、ＯＮ時の出力量（例えば、ペルチェ素子への印可電圧等）を調節しても電極の冷却度合いを調節でき、同様の効果を得ることが可能である。   FIG. 4 shows an example of a set value of the combination of the ON time and OFF time of the operation of the water generating means 7 determined according to the indoor absolute humidity and the piping temperature determined based on the information of the indoor temperature and the indoor humidity. It is. For example, the output of the water generating means 7 is ON / OFF repeatedly at a predetermined ON time and a predetermined OFF time, and the output time is adjusted by changing the combination of the ON time and the OFF time, that is, the degree of cooling of the electrode Can be adjusted. The output of the water generating means 7 not only changes the ON / OFF time, but also adjusts the degree of cooling of the electrode by adjusting the output amount at the time of ON (for example, the applied voltage to the Peltier element), Similar effects can be obtained.

ここで、図４に示すように、水発生手段７のＯＮ時間は絶対湿度が低い程長く設定し、ＯＦＦ時間は絶対湿度が低い程短くなるように設定されている。さらに、配管温度が高い程、ＯＮ時間を長くし、ＯＦＦ時間を短くなるように設定されている。よって、室内の絶対湿度が低いときや配管温度（吹出温度）が高いときは、電極への水の結露が生じにくい環境のため電極の冷却度合いを増やし、室内の絶対湿度が高いときや配管温度（吹出温度）が低いときは、電極への水の結露が生じやすい状態のため電極の冷却度合いを減らし、室内の絶対湿度や吹出温度の変化によらず電極表面での水の生成量を最適に保つことができる。つまり、静電霧化によって生じるラジカルやイオン等を含んだ微細な水粒子の粒子径がより小さく且つ粒子の個数がより多くなるような放出状態を安定して保つことができ、室内機の吹出温度によらず常に高い浄化性能を得ることができる。   Here, as shown in FIG. 4, the ON time of the water generating means 7 is set longer as the absolute humidity is lower, and the OFF time is set shorter as the absolute humidity is lower. Furthermore, the higher the pipe temperature, the longer the ON time and the shorter the OFF time. Therefore, when the indoor absolute humidity is low or the piping temperature (blowing temperature) is high, the degree of cooling of the electrode is increased to prevent the condensation of water on the electrode, and when the indoor absolute humidity is high or the piping temperature When the (blowing temperature) is low, water condensation on the electrode is likely to occur, so the degree of cooling of the electrode is reduced, and the amount of water generated on the electrode surface is optimized regardless of changes in the indoor absolute humidity or blowing temperature Can be kept in. In other words, it is possible to stably maintain a discharge state in which the diameter of fine water particles containing radicals and ions generated by electrostatic atomization is smaller and the number of particles is larger. High purification performance can always be obtained regardless of temperature.

図５は、室内温度と室内湿度の情報を基に判断される室内の絶対湿度と風量に応じて決定される水発生手段７の運転のＯＮ時間とＯＦＦ時間の組み合わせの設定値を示す一例である。ここで、図５に示すように、水発生手段７のＯＮ時間は絶対湿度が低い程長く設定し、ＯＦＦ時間は絶対湿度が低い程短くなるように設定されている。さらに、浄化ユニット周辺に送風される送風機風量が弱い程、ＯＮ時間を長くし、ＯＦＦ時間を短くなるように設定されている。   FIG. 5 is an example showing a set value of a combination of an ON time and an OFF time of the operation of the water generating means 7 determined according to the indoor absolute humidity and the air volume determined based on the information of the indoor temperature and the indoor humidity. is there. Here, as shown in FIG. 5, the ON time of the water generating means 7 is set longer as the absolute humidity is lower, and the OFF time is set shorter as the absolute humidity is lower. Furthermore, the ON time is set longer and the OFF time is set shorter as the blower air volume blown around the purification unit is weaker.

よって、室内の絶対湿度が低いときや送風機風量が弱いとき（浄化ユニットへの湿気を含んだ空気の供給量が少ないとき）は、電極への水の結露が生じにくい環境のため電極の冷却度合いを増やし、室内の絶対湿度が高いときや送風機風量が強いときは、電極への水の結露が生じやすい状態のため電極の冷却度合いを減らし、室内の絶対湿度や送風機風量の変化によらず電極表面での水の生成量を最適に保つことができる。つまり、静電霧化によって生じるラジカルやイオン等を含んだ微細な水粒子の粒子径がより小さく且つ粒子の個数がより多くなるような放出状態を安定して保つことができ、室内機の送風機風量によらず常に高い浄化性能を得ることができる。   Therefore, when the absolute humidity in the room is low or the air flow rate of the blower is weak (when the amount of air containing moisture to the purification unit is low), the degree of cooling of the electrode is limited because of the environment in which water condensation on the electrode is unlikely to occur. When the absolute humidity in the room is high or the blower air flow is strong, the degree of cooling of the electrode is reduced because the water tends to condense on the electrode, and the electrode is not affected by changes in the indoor absolute humidity or blower air flow. The amount of water generated on the surface can be kept optimal. That is, it is possible to stably maintain a discharge state in which fine water particles containing radicals and ions generated by electrostatic atomization have a smaller particle diameter and a larger number of particles. High purification performance can always be obtained regardless of the air volume.

図６は、室内機の配管温度（吹出温度）に応じて決定される水発生手段７および高電圧
印加手段６の出力のＯＮ／ＯＦＦ設定を示す一例である。
図６において、室内温度と室内湿度の情報を基に判断された絶対湿度が所定範囲内（絶対湿度：中）の場合、配管温度（吹出温度）がＴ１ａを超えると水発生手段７と高電圧印加手段６の出力をＯＦＦし、Ｔ１ａ以下では水発生手段７と高電圧印加手段６の出力をＯＮするように制御する。これによって、配管温度（吹出温度）が所定値Ｔ１ａを超えた場合、電極表面の温度が露点温度以下に下がらず、電極への水の結露が生じないと判断し、水発生手段７や高電圧印可手段６への不必要な通電を停止し、より効率的な運転を行うことができるとともに、電極に水が付着していない状態で放電することによる電極の劣化も防止することができる。 FIG. 6 is an example showing ON / OFF setting of the outputs of the water generating means 7 and the high voltage applying means 6 determined according to the piping temperature (blowing temperature) of the indoor unit.
In FIG. 6, when the absolute humidity determined on the basis of the information on the room temperature and the room humidity is within a predetermined range (absolute humidity: medium), the water generating means 7 and the high voltage when the pipe temperature (blowing temperature) exceeds T1a. The output of the applying means 6 is turned off, and the control is performed so that the outputs of the water generating means 7 and the high voltage applying means 6 are turned on at T1a or less. As a result, when the pipe temperature (blowing temperature) exceeds the predetermined value T1a, it is determined that the temperature of the electrode surface does not fall below the dew point temperature, and no water condensation occurs on the electrode, and the water generating means 7 and the high voltage Unnecessary energization to the applying means 6 can be stopped and more efficient operation can be performed, and deterioration of the electrode due to discharge without water adhering to the electrode can also be prevented.

なお、絶対湿度が所定範囲より高い場合（絶対湿度：高）は、配管温度（吹出温度）がＴ１ｃを超えると水発生手段７と高電圧印加手段６の出力をＯＦＦし、絶対湿度が所定範囲より低い場合（絶対湿度：低）は、配管温度（吹出温度）がＴ１ｂを超えると水発生手段７と高電圧印加手段６の出力をＯＦＦする。ここで、Ｔ１ｂ＜Ｔ１ａ＜Ｔ１ｃの関係になるように設定する。つまり、浄化ユニット周辺を流れる吹出気流の絶対湿度が低い程、より低い吹出温度で電極表面の温度が露点温度以上になるため、水発生手段７と高電圧印加手段６の出力をＯＦＦする配管温度（吹出温度）をより低く設定し、吹出温度と絶対湿度の変化に応じて浄化ユニット１の電極に水が結露しない状況を的確に判断することができる。   When the absolute humidity is higher than the predetermined range (absolute humidity: high), the output of the water generating means 7 and the high voltage applying means 6 is turned off when the pipe temperature (blowing temperature) exceeds T1c, and the absolute humidity is within the predetermined range. If it is lower (absolute humidity: low), the output of the water generating means 7 and the high voltage applying means 6 is turned off when the pipe temperature (blowing temperature) exceeds T1b. Here, the relationship is set such that T1b <T1a <T1c. That is, the lower the absolute humidity of the blown airflow flowing around the purification unit, the lower the temperature of the electrode surface is at the dew point or higher at the lower blowout temperature. (Blowout temperature) is set lower, and it is possible to accurately determine the situation in which water does not condense on the electrodes of the purification unit 1 according to changes in the blowout temperature and absolute humidity.

また、図６において、配管温度（吹出温度）がＴ２以下になると水発生手段７と高電圧印加手段６の出力をＯＦＦし、Ｔ２を超えると水発生手段７と高電圧印加手段６の出力をＯＮするように制御する。これによって、配管温度（吹出温度）がＴ２以下になることで電極表面で水が氷結したと判断し、水発生手段や高電圧印可手段への不必要な通電を停止するとともに、氷結が溶けて水に戻ることで再度正常な放電が可能となり、電極からラジカルやイオン等を含んだ微細な水粒子を持続して放出することができ、浄化性能を常に維持することができる。   Further, in FIG. 6, when the pipe temperature (blowing temperature) becomes T2 or less, the outputs of the water generating means 7 and the high voltage applying means 6 are turned off. When the pipe temperature exceeds T2, the outputs of the water generating means 7 and the high voltage applying means 6 are turned off. Control to turn on. As a result, it is determined that water has frozen on the electrode surface when the pipe temperature (blowing temperature) is T2 or less, and unnecessary energization to the water generating means and high voltage applying means is stopped, and the ice is melted. By returning to water, normal discharge can be performed again, and fine water particles containing radicals, ions, and the like can be continuously released from the electrode, and the purification performance can always be maintained.
