しかしながら、上記した従来の微生物繁殖防止方法および装置は、物体の表面や収納空間に存在する微生物を処理対象とするものであるが、生成されたイオン等は非常に不安定なため、イオンとしての寿命が非常に短く、物体に吹き付けるまえに安定な物質に変化してしまい、十分に微生物の繁殖を防止することができない、という課題を有していた。   However, although the above-described conventional method and apparatus for preventing microbial growth are intended to treat microorganisms present on the surface of the object or the storage space, the generated ions are very unstable, The lifetime was very short, and it changed into a stable substance before spraying on an object, and it had the subject that reproduction of microorganisms could not be prevented enough.

It is possible to provide an optimum water supply amount to the electrode and high voltage application amount for the production of fine water particles.

本発明によれば、電極から発生するラジカルやイオン等を含んだ微細な水粒子の生成のために最適な電極への水供給量および高電圧の印可量を与え、室内の環境条件に応じてより効率的且つ効果の高い浄化運転を行うことができる浄化装置を提供できる。   According to the present invention, it is possible to provide an optimal amount of water supply to the electrode and high voltage application amount for the production of fine water particles containing radicals and ions generated from the electrode, and according to indoor environmental conditions. It is possible to provide a purification apparatus capable of performing a more efficient and highly effective purification operation.

第１の発明は、放電電極および対向電極と、前記電極間に高電圧を印加して放電させる高電圧印加手段と、前記放電電極および／または前記対向電極に水を発生させる水発生手段と、空気の温度を検出する温度検出手段と、空気の湿度を検出する湿度検出手段とを備え、前記温度検出手段と前記湿度検出手段とからの検知情報に基づいて、前記水発生手段の出力および／または前記高電圧印加手段の出力を制御することを特徴とするもので、、
室内の温度、湿度条件に応じて、電極から発生するラジカルやイオン等を含んだ微細な水粒子の生成のために最適な電極への水供給量および高電圧の印可量を与えることができ、室内の温度、湿度条件の変化によらず常に高い浄化性能を発揮することができる。 The first invention comprises a discharge electrode and a counter electrode, a high voltage applying means for applying a high voltage between the electrodes for discharge, a water generating means for generating water in the discharge electrode and / or the counter electrode, Temperature detection means for detecting the temperature of the air and humidity detection means for detecting the humidity of the air, and based on detection information from the temperature detection means and the humidity detection means, the output of the water generation means and / or Alternatively, the output of the high voltage applying means is controlled,

第２の発明は、特に、第１の発明において、温度検出手段と湿度検出手段とからの検知情報から導き出される絶対湿度に基づいて、水発生手段の出力時間および／または出力量を変更するもので、特に絶対湿度が低いほど、水発生手段の出力時間および／または出力量を増加すると、電極をより冷却できるため、絶対湿度の低下による電極表面での水の生成量の減少を抑制することができ、低湿度環境でも電極から発生するラジカルやイオン等を含んだ微細な水粒子を十分に放出することができる。   In the second invention, in particular, in the first invention, the output time and / or output amount of the water generating means is changed based on the absolute humidity derived from the detection information from the temperature detecting means and the humidity detecting means. In particular, the lower the absolute humidity, the more the electrode can be cooled by increasing the output time and / or output amount of the water generating means, thereby suppressing the decrease in the amount of water generated on the electrode surface due to the decrease in absolute humidity. Therefore, fine water particles containing radicals and ions generated from the electrodes can be sufficiently released even in a low humidity environment.

第３の発明は、特に、第１の発明または第２の発明において、水発生手段は、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、前記ＯＮ時間と前記ＯＦＦ時間の組み合わせを変更することで出力時間を増減させるもので、電極の冷却度合いを変化させて、室内の温度、湿度条件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、電極から発生するラジカルやイオン等を含んだ微細な水粒子を安定して放出することができる。   According to a third invention, in particular, in the first invention or the second invention, the water generating means repeats ON / OFF at a predetermined ON time and a predetermined OFF time, and a combination of the ON time and the OFF time. By changing the output time, the degree of cooling of the electrode can be changed, and the amount of water generated on the electrode surface can be kept optimal regardless of changes in indoor temperature and humidity conditions. It is possible to stably release fine water particles containing radicals and ions generated from the water.

第４の発明は、特に、第１の発明〜第３の発明のいずれかにおいて、水発生手段は、ペルチェ素子を利用するもので、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 particular, according to a fourth invention, in any one of the first to third inventions, the water generating means uses a Peltier element, and radicals and ions generated from the electrodes, and a fine structure including them. Water required for the production of water particles can be supplied without water supply, and a purification effect can be obtained without requiring the residents to supply water.

第５の発明は、特に、第４の発明において、ペルチェ素子の吸熱側温度を検出する吸熱温度検出手段を設け、前記吸熱温度検出手段が検出した吸熱側温度が、温度検出手段と湿度検出手段とからの検知情報から導き出される露点温度よりも高い時、水発生手段の出力および高電圧印加手段の出力を停止するもので、電極表面での水の生成に必要なペルチェ素子の冷却能力の不足を判断し、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。さらに、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。   The fifth invention is the fourth invention, in particular, in the fourth invention, provided with an endothermic temperature detecting means for detecting the endothermic temperature of the Peltier element, and the endothermic temperature detected by the endothermic temperature detecting means is the temperature detecting means and the humidity detecting means. When the temperature is higher than the dew point temperature derived from the detection information, the output of the water generating means and the output of the high voltage applying means are stopped, and the cooling capacity of the Peltier element necessary for water generation on the electrode surface is insufficient Thus, unnecessary power supply to the water generating means and the high voltage applying means is stopped, and more efficient operation can be performed. Furthermore, it is possible to prevent the electrode from being deteriorated by discharging the electrode without water.

第６の発明は、特に、第４の発明または第５の発明において、ペルチェ素子の吸熱側温度を検出する吸熱温度検出手段を設け、前記吸熱温度検出手段が検出した吸熱側温度が、氷点よりも所定温度以上低い時、水発生手段の出力および高電圧印加手段の出力を停止するもので、電極表面で水が氷結したことを判断し、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る。   In particular, the sixth invention is the fourth invention or the fifth invention, wherein the endothermic temperature detecting means for detecting the endothermic temperature of the Peltier element is provided, and the endothermic temperature detected by the endothermic temperature detecting means is less than the freezing point. When the temperature is lower than a predetermined temperature, the output of the water generating means and the output of the high voltage applying means are stopped. Judging that the water has frozen on the electrode surface, it is unnecessary for the water generating means and the high voltage applying means. When the energization is stopped and the freezing melts and returns to the water, normal discharge is possible again, and fine water particles containing radicals, ions, etc. can be continuously released from the electrode.

第７の発明は、特に、第４の発明から第６の発明のいずれかにおいて、ペルチェ素子の放熱側温度を検出する放熱温度検出手段を設け、前記吸熱温度検出手段が検出した放熱側温度が、所定温度より高い時、水発生手段の出力および高電圧印加手段の出力を停止するもので、ペルチェ素子の放熱側温度が上昇しすぎること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。   In a seventh aspect of the invention, in particular, in any one of the fourth to sixth aspects of the present invention, a heat radiation temperature detecting means for detecting a heat radiation side temperature of the Peltier element is provided, and the heat radiation side temperature detected by the endothermic temperature detection means is When the temperature is higher than a predetermined temperature, the output of the water generating means and the output of the high voltage applying means are stopped, and an excessive heat load on the Peltier element due to excessive increase of the heat radiation side temperature of the Peltier element is prevented, and the Peltier element Can prevent a decrease in the service life.

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. Note that the present invention is not limited to the embodiments.

（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。 (Embodiment 1)
FIG. 1 is an example showing a configuration diagram of a purification device according to a first embodiment of the present invention.

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。   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。   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.

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。   When a 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 from the tip of the discharge electrode 2 (a phenomenon in which water is atomized by electrostatic force to release mist) As a result, radicals, ions, etc., 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はペルチェ素子等の水発生手段７の放熱面の温度を検出する放熱温度検出手段、１０は冷却面の温度を検出する吸熱温度検出手段であり、電極の冷え度合いやペルチェ素子等の水発生手段７に対する熱負荷の度合いを判断し、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。   9 is a heat radiation temperature detecting means for detecting the temperature of the heat radiating surface of the water generating means 7 such as a Peltier element, and 10 is an endothermic temperature detecting means for detecting the temperature of the cooling surface. It is provided to judge the degree of heat load on the means 7 and to control the output of the water generating means 7 and the high voltage applying means 6.

１１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、１２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 11 denotes 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 reference numeral 12 denotes 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およびその制御方法の制御ブロック図を示す一例である。図２において、５は、室内温度検出手段１、室内湿度検出手段２、放熱温度検出手段３、吸熱温度検出手段４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. 2 is an example showing a control block diagram of the purification device and the control method thereof according to the first embodiment of the present invention. In FIG. 2, reference numeral 5 denotes 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 1, the indoor humidity detecting means 2, the heat radiation temperature detecting means 3, and the endothermic temperature detecting means 4. Purifying device control means for controlling.

図３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. 3 is an example showing the setting 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 determined based on the indoor temperature and indoor humidity information. 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、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。よって、室内の絶対湿度が低いときは電極の冷却度合いを増やし、室内の絶対湿度が高いときは電極の冷却度合いを減らし、室内の絶対湿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、室内の絶対湿度によらず常に高い浄化性能を得ることができる。   Here, 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. Therefore, the degree of cooling of the electrode is increased when the absolute humidity in the room is low, and the degree of cooling of the electrode is decreased when the absolute humidity in the room is high. Can be kept optimal. In other words, it is possible to stably maintain an emission state in which the particle diameter of fine water particles containing radicals and ions generated by electrostatic atomization is smaller and the number of particles is larger, and the indoor absolute humidity Regardless of this, high purification performance can always be obtained.

次に、図４は、ペルチェ素子等の水発生手段７の吸熱側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４において、Ｔ１は、室内温度と室内湿度の情報を基に判断された露点温度に設定され、吸熱側温度がＴ１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、Ｔ１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、電極表面での水の生成に必要なペルチェ素子の冷却能力の不足を判断し、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。さらに、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。   Next, FIG. 4 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 heat absorption side temperature of the water generating means 7 such as a Peltier element. In FIG. 4, T1 is set to the dew point temperature determined based on the information on the room temperature and the room humidity. When the endothermic temperature exceeds T1, the outputs of the water generating means 7 and the high voltage applying means 6 are turned off. Below T1, control is performed so that the outputs of the water generating means 7 and the high voltage applying means 6 are turned on. As a result, the lack of cooling capacity of the Peltier element necessary for the generation of water on the electrode surface is judged, unnecessary energization to the water generating means 7 and the high voltage applying means 6 is stopped, and more efficient operation is performed. It can be carried out. Furthermore, it is possible to prevent deterioration of the electrode due to discharge in a state where water is not attached to the electrode.

また、図４において、Ｔ２は、氷点（０℃）よりも所定温度以上低い温度に設定され、吸熱側温度が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、吸熱側温度がＴ２以下になることで電極表面の水の氷結を判断し、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。   In FIG. 4, T2 is set to a temperature lower than the freezing point (0 ° C.) by a predetermined temperature or more, and when the heat absorption side temperature becomes T2 or less, the outputs of the water generating means 7 and the high voltage applying means 6 are turned off. Is exceeded, the output of the water generating means 7 and the high voltage applying means 6 is controlled to be turned on. As a result, the temperature on the heat absorption side becomes T2 or less, so that the icing of water on the electrode surface is judged, and unnecessary energization to the water generating means and the high voltage applying means is stopped, and the icing melts and returns to water. Thus, normal discharge becomes possible again, and fine water particles containing radicals and ions can be continuously released from the electrode, so that the purification performance can always be maintained.

次に、図５は、ペルチェ素子等の水発生手段７の放熱側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５において、例えば、浄化ユニット１に流入する空気の温度が過度に上昇する等により、放熱側温度が所定のＴ１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、Ｔ１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。これよって、ペルチェ素子の放熱側温度が上昇しすぎること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。   Next, FIG. 5 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 heat radiation side temperature of the water generating means 7 such as a Peltier element. In FIG. 5, for example, when the temperature of the heat radiation side exceeds a predetermined T1 due to an excessive increase in the temperature of the air flowing into the purification unit 1, the outputs of the water generating means 7 and the high voltage applying means 6 are turned off. Below, it controls so that the output of the water generation means 7 and the high voltage application means 6 may be turned ON.
