Description

本発明は、空気中の塵埃などを捕集する音波を用いた電気集塵装置の制御装置を有する空気調和機に関するものである。   The present invention relates to an air conditioner having a control device for an electrostatic precipitator that uses sound waves that collect dust in the air.

従来、空気調和機の電気集塵装置は主として所謂コロナ放電を発生して通過する塵埃粒子を帯電させる機能を持つ荷電部と、帯電または凝集した塵埃粒子を捕獲する集塵部とからなり、ユニットとして構成されて空気調和機の室内機の空気吸込み口に設置され、空気調和機が動作している場合には音波発生手段に常時一定量の電圧を印加し、塵埃を捕集していた（例えば、特許文献１参照）。
特開平１１−１５１４５２号公報 2. Description of the Related Art Conventionally, an electric dust collector of an air conditioner mainly comprises a charging unit having a function of charging so-called corona discharge and charging dust particles passing therethrough, and a dust collecting unit for capturing charged or aggregated dust particles. When the air conditioner is in operation, it is applied as a constant amount of voltage to the sound wave generating means to collect dust ( For example, see Patent Document 1).
Japanese Patent Laid-Open No. 11-151452

しかしながら、塵埃を捕集する場合は常時一定量の電圧を印加し、部屋の空気中の塵埃が少なくても常に一定の消費電力が必要となるという課題を有していた。   However, when collecting dust, a constant amount of voltage is always applied, and there is a problem that constant power consumption is always required even if there is little dust in the room air.

本発明はこのような従来の課題を解決するものであり、塵埃が少ないときには音波発生手段の消費電力を低減することを目的とする。   The present invention solves such a conventional problem, and an object of the present invention is to reduce the power consumption of the sound wave generating means when there is little dust.

上記課題を解決するため本発明は、荷電部と集塵部と荷電部のうち放電部位に対して音波を照射する音波発生手段を有する電気集塵装置と、前記音波発生手段を制御する音波制御手段と空気中の塵埃量を検出する塵埃量検出手段を有する。   In order to solve the above-described problems, the present invention provides an electric dust collector having a sound wave generating means for irradiating a discharge portion of a charged portion, a dust collecting portion, and a charged portion with sound waves, and a sound wave control for controlling the sound wave generating means. And dust amount detection means for detecting the amount of dust in the air.

また本発明は、塵埃量検出手段は塵埃量の度合いを少なくとも２つの塵埃度合いに分けて検出することを特徴とする。   Further, the present invention is characterized in that the dust amount detection means detects the dust amount by dividing it into at least two dust levels.

また本発明は、音波制御装置は前記塵埃量検出手段の塵埃度合いに応じて、塵埃度合いが所定値より高ければ前記音波発生手段に通電し、塵埃度合いが所定値より低ければ音波発生手段への通電を停止することを特徴とする。   Further, according to the present invention, the sound wave control device energizes the sound wave generating means according to the dust level of the dust amount detecting means if the dust level is higher than a predetermined value, and supplies the sound wave generating means to the sound wave generating means if the dust level is lower than the predetermined value. It is characterized by stopping energization.

また本発明は、音波制御装置は前記塵埃量検出手段の塵埃度合いに応じて、塵埃度合いが所定値より高ければ音波の音圧量を増加し,塵埃度合いが所定値より低ければ音圧量を減少することを特徴とする。   Further, according to the present invention, the sound wave control device increases the sound pressure level of the sound wave if the dust level is higher than a predetermined value, and increases the sound pressure level if the dust level is lower than the predetermined value, according to the dust level of the dust level detection means. It is characterized by decreasing.

さらに本発明は、音波制御装置は前記塵埃量検出手段の塵埃度合いに応じて、塵埃度合いが所定値より高ければ音波の周波数を増加し,塵埃度合いが所定値より低ければ音波の周波数を減少することを特徴とする。   Further, according to the present invention, the sound wave control device increases the sound wave frequency if the dust degree is higher than a predetermined value, and decreases the sound wave frequency if the dust degree is lower than the predetermined value, according to the dust degree of the dust amount detecting means. It is characterized by that.

上記構成により、塵埃量を検出し,塵埃量が少ない場合は,音波発生量を減少させることで音波発生手段の消費電力を低減することが可能となる。   With the above configuration, when the amount of dust is detected and the amount of dust is small, the power consumption of the sound wave generating means can be reduced by reducing the sound wave generation amount.

本発明の空気調和機は、使用消費電力を低減するという効果を奏する。   The air conditioner of the present invention has an effect of reducing power consumption.

第１の発明は、荷電部と、集塵部と、前記荷電部のうち放電部位に対して音波を照射する音波発生手段を有する電気集塵装置と、前記音波発生手段を制御する音波制御手段と空気中の塵埃量を検出する塵埃量検出手段を有し、塵埃量検出手段は塵埃量の度合いを少なくとも２つの塵埃度合いに分けて検出し、塵埃度合いが所定値より高ければ前記音波発生手段に通電し、塵埃度合いが所定値より低ければ音波発生手段への通電を停止することにより、使用消費電力を低減するという効果を奏する。   1st invention is an electric dust collector which has a sound wave generation means which irradiates a sound wave with respect to a discharge part among charge parts, a dust collection part, and the above-mentioned charge part, and a sound wave control means which controls the sound wave generation means And dust amount detecting means for detecting the amount of dust in the air. The dust amount detecting means detects the amount of dust divided into at least two dust levels, and if the dust level is higher than a predetermined value, the sound wave generating means If the degree of dust is lower than a predetermined value, the energization to the sound wave generating means is stopped, thereby reducing the power consumption.

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）
本発明の実施の形態１における空気調和機のシステム構成図ならびに電気集塵機構成図を図１および図２に示す。空気調和機は概略、空調すべき空間に配置されている室内機１と屋外に配置された図示されていない室外機と、熱媒体の循環路とを有している。室内機１は電気集塵装置２と塵埃検出手段３と音波制御手段４と熱交換器5と風量調整可能な室内ファン６とを有する。電気集塵装置２は荷電部２−１と集塵部２−２と荷電部２−１のうち放電部位に対して音波を照射する音波発生手段７を有する。そしてこの構成によれば、荷電部２−１において発生するコロナ放電の発生領域をより広範に拡大させることができると共に、粒子間相互の衝突確率を高めることもでき粒子相互の凝集を助長し、もって電気集塵装置２の塵埃捕集効率を向上させることが可能となる。 (Embodiment 1)
1 and 2 show a system configuration diagram and an electric dust collector configuration diagram of an air conditioner according to Embodiment 1 of the present invention. The air conditioner generally includes an indoor unit 1 arranged in a space to be air-conditioned, an outdoor unit not shown arranged outdoors, and a heat medium circulation path. The indoor unit 1 includes an electric dust collector 2, dust detection means 3, sound wave control means 4, a heat exchanger 5, and an indoor fan 6 with adjustable air volume. The electrostatic precipitator 2 includes a sound wave generation means 7 that irradiates a discharge part among the charging part 2-1, the dust collecting part 2-2, and the charging part 2-1. And according to this structure, while the generation | occurrence | production area | region of the corona discharge which generate | occur | produces in the charging part 2-1 can be expanded more widely, the collision probability between particles can also be raised, and cohesion of particles is promoted, Accordingly, the dust collection efficiency of the electric dust collector 2 can be improved.

次に音波発生手段７の消費電力削減方法を説明する。塵埃検出手段３において空調すべき空間の塵埃量を検出し、あらかじめ設定されている塵埃量レベルＷに分ける。音波制御手段４において塵埃レベルＷに応じてあらかじめ設定された音波の音圧Ｎもしくは音波の周波数Ｆを出力するよう音波発生手段7に印加する電圧を制御する。従って、塵埃レベルＷが高いすなわち塵埃量が多いときには音波発生手段7に印加する電圧を高くすることで塵埃の集塵量を高くする。また、塵埃量が少ない場合は、音波発生手段7に印加する電圧を少なくすることで塵埃の集塵量を低くする。特に塵埃量が非常に少ない場合は、音波発生手段7への電圧の印加を停止する。以上のように塵埃量に応じて音波発生手段への電圧の印加量を変化させることで、必要最低限の消費電力に削減することが可能である。   Next, a method for reducing power consumption of the sound wave generator 7 will be described. The dust detection means 3 detects the amount of dust in the space to be conditioned and divides it into a preset dust amount level W. The sound wave control means 4 controls the voltage applied to the sound wave generation means 7 so as to output the sound pressure N of the sound wave or the frequency F of the sound wave set in advance according to the dust level W. Therefore, when the dust level W is high, that is, the amount of dust is large, the amount of dust collected is increased by increasing the voltage applied to the sound wave generating means 7. Further, when the amount of dust is small, the amount of dust collected is lowered by reducing the voltage applied to the sound wave generating means 7. In particular, when the amount of dust is very small, the application of voltage to the sound wave generating means 7 is stopped. As described above, by changing the amount of voltage applied to the sound wave generating means according to the amount of dust, it is possible to reduce to the minimum necessary power consumption.

以上のように、本発明にかかる空気調和機は消費電力を低減する集塵装置を搭載しているので、空気清浄機にも応用できる。   As described above, since the air conditioner according to the present invention is equipped with a dust collector that reduces power consumption, it can also be applied to an air purifier.
