＜産業上の利用分野＞
本考案は空調換気扇に関し、殊に電位差を利用
して風を起こす方式の空調換気扇に関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an air-conditioning ventilation fan, and particularly to an air-conditioning ventilation fan that generates wind using a potential difference.
＜従来の技術＞
周知の通り、この種の空調換気扇としては、
給・排気用の送風フアンの駆動により、室内空気
を室外へ排出して室内空気中の汚染物質例えば
CO2，COや湿気等を除去すると同時に、室外空
気を排出される室内空気と熱交換させた後に室内
へ吐出する構成のものがある。<Conventional technology> As is well known, this type of air conditioning ventilation fan
By driving the supply/exhaust fan, indoor air is discharged outdoors and pollutants in the indoor air are removed.
There is a system that removes CO 2 , CO, moisture, etc., and at the same time exchanges heat between outdoor air and exhausted indoor air before being discharged indoors.
ところで、かかる従来の空調換気扇の給排気運
転は送風フアンを駆動することにより行なわれる
ので、送風フアンの駆動騒音が発生する。このた
め、この種の空調換気扇を寝室に設置した場合、
使用者（特に病人や乳児）によつては、特に夜間
時に安眠のため意図的に運転を停止することがあ
り、結果的に空調換気扇を充分に活用していない
という不都合があつた。因に、構造上その気密性
が比較的高い近年の一般住宅では、例えば13m2程
度の寝室に２人で睡眠したときに炭酸ガス濃度が
2500ppmを越えることがあることも知られてお
り、このように最も換気を必要とする状況下で騒
音のために空調換気扇が使用されないことは、重
大なマイナス点であるといえる。 By the way, since the supply/exhaust operation of such a conventional air conditioning ventilation fan is performed by driving a blower fan, driving noise of the blower fan is generated. For this reason, if you install this type of air conditioning ventilation fan in your bedroom,
Some users (particularly sick people and infants) sometimes intentionally stop the operation especially at night to get a good night's sleep, resulting in the inconvenience of not fully utilizing the air conditioning ventilation fan. Incidentally, in recent years, ordinary houses have relatively high airtightness due to their structure, and when two people sleep in a bedroom of about 13m2 , the carbon dioxide concentration increases.
It is known that air pollution levels can exceed 2,500 ppm, and the fact that air-conditioning fans are not used due to the noise in situations where ventilation is most needed is a serious disadvantage.
また、室外空気の取り入れに際しては、粉塵等
の除去のため一般にフイルタを備えているが、フ
イルタを設けると圧力損失が大きくなるため、送
風フアンの駆動力を大きくする必要があり、騒音

向は集塵機能に優れた細密なフイルタ程著しくな
る。更にこのようなフイルタを設けたとしても、
近年問題とされている花粉等アレルギーの原因と
なるような微粒粉塵まで除去することは困難であ
つた。 In addition, when taking in outdoor air, a filter is generally installed to remove dust, etc., but installing a filter increases pressure loss, so it is necessary to increase the driving force of the blower fan, which increases noise. This also increases power consumption. This tendency becomes more pronounced as the filter becomes finer and has a better dust collection function. Furthermore, even if such a filter is installed,
It has been difficult to remove even the fine dust particles that cause allergies, such as pollen, which has become a problem in recent years.
更に、従来の空調換気扇は、熱交換時における
熱交換効率が大略60〜80％程度であり、熱エネル
ギーのロスが大きい。即ち、例えば13m2（33m3）
の部屋に２人が在室して１時間で合計６本の喫煙

1000ppm以下にするには60m3／hrの換気で良い
が、このときの粉塵量はビル管理法の２倍程度で
ある0.29mg／m3であり、該数値を基準値である
0.15mg／m3以下に抑えるためには120m3／hrもの
換気が必要であり、かかる換気を行うことによる
熱ロスが非常に大きいものである。 Furthermore, in conventional air conditioning ventilation fans, the heat exchange efficiency during heat exchange is approximately 60 to 80%, resulting in a large loss of thermal energy. i.e. for example 13m 2 (33m 3 )
If two people are in a room and smoke a total of six cigarettes in one hour, the carbon dioxide concentration in the room is
Ventilation at a rate of 60m 3 /hr is sufficient to reduce the amount to 1000ppm or less, but the amount of dust at this time is 0.29mg/m 3 , which is about twice the amount of the building management law, and this value is the standard value.
In order to keep it below 0.15 mg/m 3 , ventilation of 120 m 3 /hr is required, and the heat loss caused by such ventilation is extremely large.
＜考案が解決しようとする問題点＞
このように、室内空気の清浄化という観点から
はできるだけ多量の換気を行うことが有利である
が、省エネという観点からはその換気運転を必要
最小風量に抑えることが好ましく、両者をともに
満足させるとともに、駆動騒音のない静かな運転
を自動的に行う空調換気扇の提供が汎く要望され
ている。<Problem that the invention aims to solve> As described above, from the perspective of purifying indoor air, it is advantageous to provide as much ventilation as possible, but from the perspective of energy saving, it is necessary to reduce the ventilation operation to the minimum necessary air volume. It is desirable to provide an air conditioning ventilation fan that satisfies both requirements and automatically operates quietly without driving noise.
そこで、本考案は、空調換気扇を電位差により

しようとするものである。 Therefore, the present invention has an air conditioning ventilation fan configured to generate wind using a potential difference for ventilation, and also to remove dust contained in the indoor air by circulating the indoor air separately from the air conditioning ventilation operation. Moreover, by having a configuration that automatically performs the operation according to the pollution state of the indoor air, an air conditioning ventilation fan with excellent energy-saving effects that operates automatically while suppressing heat loss as much as possible without generating noise. This is what we are trying to provide.

An anode body that cationizes and a means for applying a high voltage to the cathode plate and the anode body are provided, whereby the cationized dust is adsorbed to the cathode plate side, and as the dust moves, an air flow is generated. An opening is provided between the cathode plate of at least one of the indoor air exhaust passage and the outdoor air intake passage and the heat exchanger, and a passage is provided between the opening and the cathode plate. In addition, an opening/closing means for opening and closing the passage is provided to variably control the ratio between the air flow rate circulating in the room and the ventilation flow rate via the heat exchanger. A control unit is provided to control the opening degree of the opening/closing means and the applied voltage of the high voltage applying means so as to maintain a clean level, and the heat energy loss is reduced by appropriately adjusting the ventilation flow rate and the indoor air circulation flow rate. The structure is designed to efficiently remove gaseous pollutants such as CO 2 and pollutant particles such as dust contained in the indoor air while suppressing them as much as possible.

A heat exchanger 5 for indirectly exchanging heat between the indoor air and outdoor air is disposed at the intersection.

うようになつている。 And the wind blowing electrode plates 6, 6 of the indoor air exhaust passage 3
On the passage wall between the heat exchanger and the
A damper 10 forms an opening 9 for discharging and circulating the indoor air that has passed through the space into the room again, and serves as an opening/closing means for opening and closing the opening 9.
and is provided. This damper 10 automatically controls opening and closing of the opening 9 by a control unit which will be described later. That is, when the opening 9 is opened, the discharge passage 3 is closed, when the discharge passage 3 is opened, the opening 9 is closed, and at the intermediate position, the opening 9 and the discharge passage 3 are respectively closed. It is configured to open according to the opening degree. Therefore, when the opening 9 is fully opened, the indoor air flows from the inlet of the exhaust passage 3 between the blower electrode plates 6, 6, flows through the opening 9, is discharged into the room again, and circulates inside the room. While the dust removal operation is performed, when the opening 9 is fully closed, an air conditioning ventilation operation is performed in which the indoor air flows between the blower electrode plates 6, 6, passes through the heat exchanger 5, and is discharged to the outside. Further, at the intermediate position of the damper 10, the indoor air dust removal operation and the air conditioning ventilation operation are performed in combination.

定キーボード、１５は操作スイツチである。 A control unit 11 consisting of a CPU, ROM, RAM, and I/O senses the CO 2 concentration of indoor air.
It is equipped with a CO 2 sensor 12 and a dust sensor 13 that detects dust concentration, and based on the signals from the CO 2 sensor 12 and the dust sensor 13, the detected concentration value and a predetermined air cleanliness level input in advance are detected. The amount of ventilation is calculated so that the indoor air reaches the predetermined cleanliness level by comparing it with the set value of This configuration controls the amount of electric power applied between the ionization line 6 and the ionization line 8. Note that 14 is a setting keyboard, and 15 is an operation switch.
また、１６は交流電源（AC100V）から直流高
電圧を発生して前記起風極板６，６とイオン化線

ンスである。 Further, 16 is a transformer as a high voltage applying means that generates a DC high voltage from an AC power source (AC 100V) and applies it between the blast electrode plates 6, 6 and the ionization wire 8.
次に、作用を説明する。 Next, the effect will be explained.
いま、例えば起風極板６，６の電圧を−7KV、
イオン化線８の電圧を＋13KVにそれぞれ荷電
し、対向極板７を接地（0V）すると、イオン化
線８の周囲は起風極板６，６との電位差20KVで

に対する合成ベクトルの方向の風となる。 Now, for example, if the voltage of the wind generator plates 6 and 6 is -7KV,
When the voltage of the ionization wire 8 is charged to +13KV and the opposing electrode plate 7 is grounded (0V), the area around the ionization wire 8 becomes plasma due to the potential difference of 20KV with the wind-generating electrode plates 6, 6, and the negative ions are ionized. The positive ions are collided with and absorbed by the line 8 and travel straight between the wind-generating pole plates 6, 6. At this time, due to the viscosity of the air, the surrounding air is pulled together, and the ionized wire 8 is pulled away from the bipolar plates 6, 6.
becomes the wind in the direction of the resultant vector.
一方、粉塵の粒子もイオン化線８により陽イオ

７と印加電圧−7KVの起風極板６，６との平面
電界により該起風極板６，６に押し付けられるよ
うに吸着する。 On the other hand, dust particles are also cationized by the ionization beam 8 or collide with ionized air cations to become cations (at this time, large dust particles become dielectric). Therefore, when the dust enters the negatively charged wind-generating electrode plates 6, 6, it is attracted to the electrode plates 6, 6. In addition, the dust mainly in the central part that tries to pass through without being attracted is pressed against the counter electrode plates 7 and the air electrode plates 6, 6 with an applied voltage of -7 KV due to the plane electric field between the electrode plates 6, 6. It absorbs like this.
このように、イオン化線８によりプラスに帯電
された粉塵、空気は起風極板６，６に引き寄せら

と同時に、室内空気排出通路３から室内空気が室
外に排出されて換気が行なわれる。 In this way, the dust and air that are positively charged by the ionization wire 8 are attracted to the blasting electrode plates 6, 6, and the dust is adsorbed to the electrode plates 6, 6.
Air flows between the electrode plates 6, 6 in a manner that the air is particularly attracted by the dust, and a ventilation condition is continuously created in which the air is discharged to the side opposite to the ionization line 8. As a result,
At the same time that outside air is sucked into the room from the outdoor air intake passage 4, indoor air is discharged to the outside from the indoor air exhaust passage 3, thereby performing ventilation.

きる。 Therefore, ventilation can be performed very quietly without using a fan for blowing air, which is the main cause of noise, as in the conventional case, and dust can be efficiently removed without using a filter for removing dust. In this case, since it uses dust ionization, it is possible to effectively collect and remove fine dust particles that cause pollen allergies from outdoor air. Even large amounts of dust contained therein can be removed effectively.
また、同時に発生するオゾンにより殺菌効果も

きる。 In addition, the ozone generated at the same time has a sterilizing effect and improves the cleanliness of the supplied air from a biochemical perspective, which is advantageous in terms of hygiene and maintains a favorable environment, especially for sick people and infants. can.
次に、本実施例の空調換気扇における室内空気

を、第５図も参照しつつ４例に分けて順に説明す
る。 Next, operational examples of the air-conditioning ventilation fan of this embodiment in response to a state of contamination of indoor air by CO 2 and dust will be explained in order by dividing into four examples with reference to FIG. 5 as well.

路３，４とも開通させる通常の空調換気運転を行
う。(1) When the CO 2 concentration in the indoor air is high As the CO 2 concentration increases, the CO 2 sensor 12 senses this, and the control unit 11 receives the signal from the CO 2 sensor 12 to reduce the CO 2 concentration . The concentration is compared with a pre-input setting value, the required ventilation amount is calculated, and the damper 10 is positioned so that the opening 9 is fully closed and the indoor air exhaust passage 3 is fully open. 4. Open all lines and perform normal air conditioning ventilation operation.
これにより、新鮮な外気を室内に導入するとと
もに、CO2濃度の高い汚れた室内空気を室外へ排
出する。 This allows fresh outside air to enter the room and exhausts dirty indoor air with a high concentration of CO 2 to the outside.

がより高まる。 At this time, the ventilation air volume is controlled by the control unit 1.
Ventilation operation is performed while adjusting the voltage calculated in step 1 and increasing/decreasing the voltage applied to the wind blowing electrode plates 6, 6, etc. of both passages 3, 4 according to the CO 2 concentration. In addition, since the intake air is discharged into the room while dust in the air is adsorbed by the pair of blowing electrode plates 6, 6, the cleanliness of the indoor air is further improved.

を調整維持する。(2) When the concentration of CO 2 and dust in the indoor air is high As the concentration of CO 2 and dust increases,
The CO 2 sensor 12 and the dust sensor 13 sense the signals, and the control unit 11 receives these signals and compares them with the CO 2 concentration and dust concentration settings that have been input in advance. The damper 10 is positioned so that both the indoor air discharge passage 3 and the indoor air discharge passage 9 are appropriately opened, air conditioning ventilation operation and indoor air dust removal operation are performed at the same time, and fresh outside air is introduced and dust removal is performed at the same time. At this time, the power applied to the wind generator plates 6, 6, etc. on the indoor air exhaust passage 3 side is appropriately increased or decreased according to the degree of opening of the opening 9, and the ventilation air volume is adjusted and maintained.

Reduce the amount of ventilation by reducing the power applied to the electrode plates 6, 6, etc.
