洗浄水２に酸性水溶液を用いる場合、ｐＨ２〜６であり、ミョウバン、クエン酸、シュウ酸、リン酸、ヨウ化水素、酢酸、リンゴ酸、乳酸、コハク酸、酒石酸、酪酸、フマル酸、プロピオン酸、ギ酸、過酸化水素水、電解酸性水溶液の単一または複合の水溶液等が用いられる。このような酸性水溶液からなる洗浄水２に室内の空気を接触させることで、空気中のアルカリ性物質（タバコ臭、アンモニア臭、疲労臭（汗臭、アンモニア）、パーマ液の匂い等）を、中和反応を利用して除去できる。なお、ｐＨ２〜６であるので、人体への深刻な害は発生しない。 When an acidic aqueous solution is used for the washing water 2, the pH is 2 to 6, and it is myoban, citric acid, oxalic acid, phosphoric acid, hydrogen iodide, acetic acid, malic acid, lactic acid, succinic acid, tartaric acid, butyric acid, fumaric acid, propionic acid. , Formic acid, hydrogen peroxide solution, single or composite aqueous solution of electrolytically acidic aqueous solution and the like are used. By bringing indoor air into contact with the washing water 2 composed of such an acidic aqueous solution, alkaline substances in the air (tobacco odor, ammonia odor, fatigue odor (sweat odor, ammonia), perm solution odor, etc.) can be neutralized. It can be removed using a sum reaction. Since the pH is 2 to 6, no serious harm to the human body occurs.

洗浄水２に中性な水を用いる場合、空気中の酸性物質やアルカリ性物質の中和作用は生じないが、空気が洗浄水（中性な水）に接触した際、空気中のＰＭ２．５や塵芥等の微粒子が洗浄水に捕捉され、除去される。また、ニコチン、ホルムアルデヒド等の水溶性のガス状有害物質を、水（洗浄水２）に溶け込ませて除去することもできる。なお、空気中のＰＭ２．５や塵芥等の微粒子は、洗浄水２にアルカリ性水溶液や酸性水溶液を用いた場合でも、同様に除去できることは勿論である。 When neutral water is used for the washing water 2, the neutralizing action of acidic substances and alkaline substances in the air does not occur, but when the air comes into contact with the washing water (neutral water), PM2.5 in the air Fine particles such as dust and debris are trapped in the washing water and removed. In addition, water-soluble gaseous harmful substances such as nicotine and formaldehyde can be removed by dissolving them in water (washing water 2). Needless to say, fine particles such as PM2.5 and dust in the air can be similarly removed even when an alkaline aqueous solution or an acidic aqueous solution is used for the washing water 2.

洗浄水２として用いられるアルカリ性水溶液、酸性水溶液、中性な水は、浄化する部屋の空気の状況（酸性物質が多い空気、アルカリ性物質が多い空気、塵芥のみの空気）に応じて、水槽３から適宜入れ替えられる。また、アルカリ性水溶液、酸性水溶液、中性な水が貯留された水槽３を別々に用意しておき、浄化する部屋の空気の状況に応じて、適切な洗浄水２が貯留された水槽３を使用するようにしてもよい。 The alkaline aqueous solution, acidic aqueous solution, and neutral water used as the washing water 2 are selected from the water tank 3 depending on the air condition of the room to be purified (air containing a large amount of acidic substances, air containing a large amount of alkaline substances, air containing only dust). It can be replaced as appropriate. Further, a water tank 3 in which an alkaline aqueous solution, an acidic aqueous solution, and a neutral water are stored is separately prepared, and a water tank 3 in which an appropriate cleaning water 2 is stored is used according to the air condition of the room to be purified. You may try to do it.

（ｐＨ指示薬）
洗浄水２にアルカリ性水溶液または酸性水溶液が使用された場合、その洗浄水２にｐＨ指示薬を添加してもよい。ｐＨ指示薬には、例えば、ＢＴＢ溶液、フェノールフタレイン溶液、メチルオレンジ、紫キャベツ液、リトマス等が用いられる。ｐＨ指示薬が添加されたアルカリ性水溶液または酸性水溶液は、空気中の酸性物質またはアルカリ性物質によってが中和反応が進行すると、色が経時的に変化する。かかる洗浄水２の色の経時的な変化は、図１に示すように、水槽３に設けられた透明な窓部１６から目視でき、洗浄水２の色に基づいて洗浄水２の浄化能力の有無を判断できる。なお、洗浄水２の色確認用の窓部は、水槽３の側面に設けられた窓部１６とは別に設けてもよい。 (PH indicator)
When an alkaline aqueous solution or an acidic aqueous solution is used for the washing water 2, a pH indicator may be added to the washing water 2. As the pH indicator, for example, BTB solution, phenolphthalein solution, methyl orange, purple cabbage solution, litmus and the like are used. The color of the alkaline aqueous solution or the acidic aqueous solution to which the pH indicator is added changes with time as the neutralization reaction proceeds due to the acidic substance or the alkaline substance in the air. As shown in FIG. 1, such a change in the color of the washing water 2 with time can be visually observed from the transparent window portion 16 provided in the water tank 3, and the purification capacity of the washing water 2 is based on the color of the washing water 2. You can judge the presence or absence. The window portion for confirming the color of the washing water 2 may be provided separately from the window portion 16 provided on the side surface of the water tank 3.

（ＣＯ2センサー２０）
図１に示すように、水式空気清浄機１は、室内の空気のＣＯ2濃度を測定するＣＯ2センサー２０を備えている。ＣＯ2センサー２０は、光学式（ＮＤＩＲ）、電気化学式、半導体式などのタイプが用いられ、送風手段４のファンケース１２の入口管１３に取り付けられている。ＣＯ2センサー２０の出力値は制御部１９に送られる。 (CO2 sensor 20)
As shown in FIG. 1, the water-type air purifier 1 includes a CO2 sensor 20 that measures the CO2 concentration of indoor air. The CO2 sensor 20 is of an optical type (NDIR) type, an electrochemical type, a semiconductor type, or the like, and is attached to the inlet pipe 13 of the fan case 12 of the blower means 4. The output value of the CO2 sensor 20 is sent to the control unit 19.

制御部１９は、ＣＯ2センサー２０で測定されたＣＯ2濃度の高低に応じて、送風手段４の風量を大小と制御する。すなわち、測定されたＣＯ2濃度が所定値よりも高いときには送風手段４のファンのモーターの回転速度を速め、ＣＯ2濃度が所定値以下のときには送風手段４のファンのモーターの回転速度を遅くする。所定値には、例えば、学校衛生管理マニュアルにおいて換気の基準として規定されている１５００ｐｐｍが用いられる。 The control unit 19 controls the air volume of the air blowing means 4 to be large or small according to the level of the CO2 concentration measured by the CO2 sensor 20. That is, when the measured CO2 concentration is higher than the predetermined value, the rotation speed of the fan motor of the blower means 4 is increased, and when the CO2 concentration is equal to or less than the predetermined value, the rotation speed of the fan motor of the blower means 4 is decreased. For the predetermined value, for example, 1500 ppm specified as a ventilation standard in the school hygiene management manual is used.

また、制御部１９は、ＣＯ2センサー２０で測定されたＣＯ2濃度の高低に応じて、回転手段６の回転速度を速遅と制御する。すなわち、測定されたＣＯ2濃度が所定値（例えば１５００ｐｐｍ）よりも高いときには回転手段６の棒磁石９のモーター７の回転速度を速めて洗浄水２の旋回流を強め、ＣＯ2濃度が所定値以下のときには回転手段６のモーター７の回転速度を遅くして洗浄水２の旋回流を弱める。 Further, the control unit 19 controls the rotation speed of the rotating means 6 to be fast or slow according to the level of the CO2 concentration measured by the CO2 sensor 20. That is, when the measured CO2 concentration is higher than a predetermined value (for example, 1500 ppm), the rotation speed of the motor 7 of the bar magnet 9 of the rotating means 6 is increased to strengthen the swirling flow of the washing water 2, and the CO2 concentration is equal to or less than the predetermined value. Occasionally, the rotation speed of the motor 7 of the rotating means 6 is slowed down to weaken the swirling flow of the washing water 2.

（ダストセンサー３０）
図１に示すように、水式空気清浄機１は、室内の空気中の塵芥量を測定するダストセンサー３０を備えている。ダストセンサー３は、公知のものが用いられ、送風手段４のファンケース１２の入口管１３に取り付けられている。ダストセンサー３０の出力値は制御部１９に送られる。 (Dust sensor 30)
As shown in FIG. 1, the water-type air purifier 1 includes a dust sensor 30 that measures the amount of dust in the air in the room. A known dust sensor 3 is used, and the dust sensor 3 is attached to the inlet pipe 13 of the fan case 12 of the blower means 4. The output value of the dust sensor 30 is sent to the control unit 19.

制御部１９は、ダストセンサー３０で測定された塵芥量の大小に応じて、送風手段４の風量を大小と制御する。すなわち、測定された塵芥量が所定値よりも大きいときには送風手段４のファンのモーターの回転速度を速め、塵芥量が所定値以下のときには送風手段４のファンのモーターの回転速度を遅くする。所定値には、例えば、学校衛生管理マニュアルにおいて基準値として規定されている０．１ｍｇ／ｍ3が用いられる。 The control unit 19 controls the air volume of the air blowing means 4 to be large or small according to the amount of dust measured by the dust sensor 30. That is, when the measured amount of dust is larger than the predetermined value, the rotation speed of the fan motor of the blower means 4 is increased, and when the amount of dust is equal to or less than the predetermined value, the rotation speed of the fan motor of the blower means 4 is decreased. For the predetermined value, for example, 0.1 mg / m3 specified as a reference value in the school hygiene management manual is used.

また、制御部１９は、ダストセンサー３０で測定された塵芥量の大小に応じて、回転手段６の回転速度を速遅と制御する。すなわち、測定された塵芥量が所定値（例えば０．１ｍｇ／ｍ3）よりも大きいときには回転手段６の棒磁石９のモーター７の回転速度を速めて洗浄水２の旋回流を強め、塵芥量が所定値以下のときには回転手段６のモーター７の回転速度を遅くして洗浄水２の旋回流を弱める。 Further, the control unit 19 controls the rotation speed of the rotating means 6 to be fast or slow according to the amount of dust measured by the dust sensor 30. That is, when the measured amount of dust is larger than a predetermined value (for example, 0.1 mg / m3), the rotation speed of the motor 7 of the bar magnet 9 of the rotating means 6 is increased to strengthen the swirling flow of the washing water 2, and the amount of dust is increased. When it is less than a predetermined value, the rotation speed of the motor 7 of the rotating means 6 is slowed down to weaken the swirling flow of the washing water 2.

（重量センサー２１）
図１に示すように、基台５の凹部５ａの段差には、そこに載置される水槽３の重量を測定するための重量センサー２１が設けられている。重量センサー２１は、ロードセル等からなり、洗浄水２を含めた水槽３の重量を測定し、その出力値が制御部１９に送られるようになっている。制御部１９は、水槽３内の洗浄水２の重量が蒸発によって所定量よりも減少したと判断したとき、基台５に設けられた警告灯（図示省略）を点灯または灯点させ、送風手段４および回転手段６の運転を停止させる。 (Weight sensor 21)
As shown in FIG. 1, a weight sensor 21 for measuring the weight of the water tank 3 placed therein is provided on the step of the recess 5a of the base 5. The weight sensor 21 is composed of a load cell or the like, measures the weight of the water tank 3 including the washing water 2, and sends an output value thereof to the control unit 19. When the control unit 19 determines that the weight of the washing water 2 in the water tank 3 has decreased from the predetermined amount due to evaporation, the control unit 19 lights or turns on a warning light (not shown) provided on the base 5 to blow air. 4 and the rotating means 6 are stopped.

（作用・効果）
図１に示すように、本実施形態に係る水式空気清浄機１によれば、室内の空気を水槽３内の洗浄水２の水面２ａに供給し、空気中の塵芥や有害物質を洗浄水２に接触させて捕捉させ空気を浄化しているので、フィルターの目詰まりによる風量低下は発生せず、長時間使用しても風量が低下することはない。湿式フィルター型やスクラバータイプの空気清浄機と比べると、簡単な構造なので、装置全体をコンパクトに構成でき、製造コストが安い。洗浄水２を交換することで清浄能力が維持できるので、フィルターを交換するタイプと比べてランニングコストが安い。よって、個人用（プライベート用）として好適な水式空気清浄機１となる。 (Action / effect)
As shown in FIG. 1, according to the water-type air purifier 1 according to the present embodiment, indoor air is supplied to the water surface 2a of the cleaning water 2 in the water tank 3, and dust and harmful substances in the air are cleaned water. Since the air is purified by contacting with 2 and capturing the air, the air volume does not decrease due to clogging of the filter, and the air volume does not decrease even if it is used for a long time. Compared to wet filter type and scrubber type air purifiers, the structure is simple, so the entire device can be configured compactly and the manufacturing cost is low. Since the cleaning ability can be maintained by replacing the cleaning water 2, the running cost is lower than that of the type in which the filter is replaced. Therefore, the water type air purifier 1 is suitable for personal use (private use).

図１に示すように、回転手段６によって水槽３内の洗浄水２を鉛直軸回りに回転させて洗浄水２の水面２ａを逆円錐状に窪ませ、逆円錐状に窪んだ洗浄水２の水面２ａに送風手段４によって室内の空気を上方から吹き付けているので、空気が接触する洗浄水２の水面２ａ（逆円錐状水面）の面積が、水面２ａが水平（平坦）な場合と比べて増大し、空気中の塵芥や有害物質（酸性物質、アルカリ性物質）を除去する処理能力が向上する。また、鉛直軸回りに回転している洗浄水２の水面２ａに、遠心力によって回転中心から径方向外方に向かう矢印Ｘで示すような水流が生じる。この水流は、水槽３の内壁に沿って下降し、回転中心において洗浄水２の内部から水面２ａに上昇する循環流となるので、洗浄水２の水面２ａには、洗浄水２の液体内側から汚れていない新鮮な洗浄水２が途切れること無く供給されることになり、そこに接触された空気を効率的に浄化できる。 As shown in FIG. 1, the washing water 2 in the water tank 3 is rotated about a vertical axis by the rotating means 6 to dent the water surface 2a of the washing water 2 in an inverted conical shape, and the washing water 2 dented in an inverted conical shape. Since the indoor air is blown onto the water surface 2a from above by the blowing means 4, the area of the water surface 2a (inverted conical water surface) of the washing water 2 with which the air comes into contact is larger than that when the water surface 2a is horizontal (flat). It will increase and improve the processing capacity to remove dust and harmful substances (acidic substances, alkaline substances) in the air. Further, on the water surface 2a of the washing water 2 rotating around the vertical axis, a water flow as shown by an arrow X extending radially outward from the center of rotation is generated by centrifugal force. This water flow is a circulating flow that descends along the inner wall of the water tank 3 and rises from the inside of the washing water 2 to the water surface 2a at the center of rotation. The clean and fresh cleaning water 2 is supplied without interruption, and the air in contact with the cleaning water 2 can be efficiently purified.

図１に示す水槽３内に貯留される洗浄水２にアルカリ性水溶液を用いた場合、塵芥の除去に加え、空気中の酸性物質（ＮＯx、ＳＯx、ＣＯ2ガス、ホルムアルデヒド類、加齢臭、生ゴミ臭など）を中和反応を利用して除去でき、アルカリ性の殺菌作用によって空気中のカビ菌やウィルスも除去できる。洗浄水２に酸性水溶液を用いた場合、塵芥の除去に加え、空気中のアルカリ性物質（タバコ臭、アンモニア臭、疲労臭（汗臭）、パーマ液の匂い等）を中和反応を利用して除去できる。洗浄水２にアルカリ性水溶液または酸性水溶液を使用した場合、洗浄水にｐＨ指示薬を添加し、洗浄水２の色の変化を窓部１６から目視することで、洗浄水２の中和作用による浄化能力の有無（寿命）を判断できる。 When an alkaline aqueous solution is used for the washing water 2 stored in the water tank 3 shown in FIG. 1, in addition to removing dust, acidic substances (NOx, SOx, CO2 gas, formaldehydes, aging odor, garbage) in the air are used. (Odor, etc.) can be removed by using a neutralization reaction, and mold bacteria and viruses in the air can also be removed by the alkaline bactericidal action. When an acidic aqueous solution is used for the washing water 2, in addition to removing dust, alkaline substances in the air (tobacco odor, ammonia odor, fatigue odor (sweat odor), perm solution odor, etc.) are neutralized by using a neutralization reaction. Can be removed. When an alkaline aqueous solution or an acidic aqueous solution is used for the washing water 2, a pH indicator is added to the washing water, and the change in color of the washing water 2 is visually observed from the window portion 16, thereby purifying the washing water 2 by the neutralizing action. It is possible to judge the presence or absence (lifetime) of.

図１に示す制御部１９は、温度センサー２０の出力値に応じてヒーター１７の温度を調節し、水槽３内の洗浄水２の温度を洗浄水２の種類に応じた最も効率のよい温度範囲に制御する。例えば、洗浄水２にアルカリ性水溶液として炭酸ソーダ（炭酸ナトリウム）の水溶液を用いた場合、５０℃が最も効率よく炭酸ガス（ＣＯ2ガス）を吸着するため、洗浄水２の温度を、例えば４５〜５５℃に制御する。この温度範囲は、洗浄水２の水溶液の種類に応じて最適な範囲に切り替えられるようになっており、洗浄水２の温度をその種類に応じて効率的に空気を処理できる温度に保つことができる。 The control unit 19 shown in FIG. 1 adjusts the temperature of the heater 17 according to the output value of the temperature sensor 20, and sets the temperature of the washing water 2 in the water tank 3 to the most efficient temperature range according to the type of the washing water 2. To control. For example, when an aqueous solution of sodium carbonate (sodium carbonate) is used as the alkaline aqueous solution for the washing water 2, the temperature of the washing water 2 is set to, for example, 45 to 55 because carbon dioxide gas (CO2 gas) is most efficiently adsorbed at 50 ° C. Control to ° C. This temperature range can be switched to the optimum range according to the type of the aqueous solution of the washing water 2, and the temperature of the washing water 2 can be maintained at a temperature at which air can be efficiently treated according to the type. can.

図１に示す水槽３内の洗浄水２は長時間の使用によって蒸発によって減少するところ、水槽３内の洗浄水２が所定量よりも減少したか否かは、窓部１６から目視で確認できる。蒸発した水分は排気管１５を通って室内に供給されるので、本機は加湿器としても機能する。洗浄水２に水にアロマオイルを添加したものを用いればアロマ加湿器にもなる。また、水槽３内の洗浄水２の重量は重量センサー（ロードセル）２１によって測定されており、洗浄水２の重量が所定量よりも減少したと制御部１９によって判断されたとき、基台５に設けられた警告灯が点灯または灯点され、送風手段４および回転手段６の運転が停止される。これにより、所謂、空運転を防止できる。 The washing water 2 in the water tank 3 shown in FIG. 1 decreases due to evaporation due to long-term use, and it can be visually confirmed from the window 16 whether or not the washing water 2 in the water tank 3 has decreased from a predetermined amount. .. Since the evaporated water is supplied to the room through the exhaust pipe 15, the machine also functions as a humidifier. If the washing water 2 to which aroma oil is added is used, it can also be used as an aroma humidifier. Further, the weight of the washing water 2 in the water tank 3 is measured by the weight sensor (load cell) 21, and when the control unit 19 determines that the weight of the washing water 2 is less than a predetermined amount, the base 5 is set. The provided warning light is turned on or turned on, and the operation of the blowing means 4 and the rotating means 6 is stopped. As a result, so-called idle operation can be prevented.

図１に示す制御部１９は、ＣＯ2センサー２０で測定されたＣＯ2濃度の高低に応じて送風手段４の風量を大小と制御する。すなわち、室内の空気中のＣＯ2濃度が所定値（例えば学校衛生管理マニュアルにおいて換気の基準として規定されている１５００ｐｐｍ）よりも高い場合には、送風手段４の風量が増大され、多量の室内空気が洗浄水２の水面２ａに供給されるので、室内のＣＯ2濃度を速やかに低くできる。他方、室内の空気中のＣＯ2濃度が所定値（例えば１５００ｐｐｍ）以下の場合には、送風手段４の風量が減少されるので、送風手段４のファンモーターの消費電力が軽減される。 The control unit 19 shown in FIG. 1 controls the air volume of the blower means 4 according to the level of the CO2 concentration measured by the CO2 sensor 20. That is, when the CO2 concentration in the indoor air is higher than a predetermined value (for example, 1500 ppm specified as a ventilation standard in the school hygiene management manual), the air volume of the ventilation means 4 is increased and a large amount of indoor air is generated. Since it is supplied to the water surface 2a of the washing water 2, the CO2 concentration in the room can be quickly lowered. On the other hand, when the CO2 concentration in the indoor air is a predetermined value (for example, 1500 ppm) or less, the air volume of the blower means 4 is reduced, so that the power consumption of the fan motor of the blower means 4 is reduced.

図１に示す制御部１９は、ＣＯ2センサー２０で測定されたＣＯ2濃度の高低に応じて回転手段６の回転速度を速遅と制御する。すなわち、室内の空気中のＣＯ2濃度が所定値（例えば１５００ｐｐｍ）よりも高い場合には、回転手段６の回転速度が速まって洗浄水２の旋回流が強められ、洗浄水２の水面２ａに内部の新鮮な洗浄水２が次々と現れる循環流（矢印Ｘ）が強まるので、水面２ａにおける空気の処理効率が高まり、室内のＣＯ2濃度を速やかに低くできる。他方、室内の空気中のＣＯ2濃度が所定値（例えば１５００ｐｐｍ）以下の場合には、回転手段６の回転速度が遅くなり洗浄水２の旋回流が弱められるので、回転手段のモーターの消費電力が軽減される。 The control unit 19 shown in FIG. 1 controls the rotation speed of the rotating means 6 to be fast or slow according to the level of the CO2 concentration measured by the CO2 sensor 20. That is, when the CO2 concentration in the indoor air is higher than a predetermined value (for example, 1500 ppm), the rotation speed of the rotating means 6 is increased, the swirling flow of the washing water 2 is strengthened, and the water surface 2a of the washing water 2 is reached. Since the circulating flow (arrow X) in which fresh cleaning water 2 appears one after another is strengthened, the efficiency of air treatment on the water surface 2a is increased, and the CO2 concentration in the room can be quickly lowered. On the other hand, when the CO2 concentration in the indoor air is less than a predetermined value (for example, 1500 ppm), the rotation speed of the rotating means 6 is slowed down and the swirling flow of the washing water 2 is weakened, so that the power consumption of the motor of the rotating means is reduced. It will be reduced.

なお、空気中のＣＯ2は、洗浄水２にアルカリ性水溶液を用いたときには上述した中和反応によって除去され、洗浄水２に水または酸性水溶液を用いたときには水または水溶液に溶け込むことで除去される。また、ＣＯ2センサー２０で測定されたＣＯ2濃度が所定値（例えば１５００ｐｐｍ）以下の場合には、ヒーター１７の発熱を停止させ、ヒーター１７の消費電力を軽減してもよい。 CO2 in the air is removed by the above-mentioned neutralization reaction when an alkaline aqueous solution is used for the washing water 2, and is removed by dissolving in water or an aqueous solution when water or an acidic aqueous solution is used for the washing water 2. Further, when the CO2 concentration measured by the CO2 sensor 20 is not more than a predetermined value (for example, 1500 ppm), the heat generation of the heater 17 may be stopped to reduce the power consumption of the heater 17.

図１に示す制御部１９は、ダストセンサー３０で測定された室内空気中の塵芥量の大小に応じて送風手段４の風量を大小と制御する。すなわち、室内の空気中の塵芥量が所定値（例えば学校衛生管理マニュアルにおいて換気の基準値として規定されている０．１ｍｇ／ｍ3）よりも大きい場合には、送風手段４の風量が増大され、多量の室内空気が洗浄水２の水面２ａに供給されるので、室内空気中の塵芥量を速やかに減少できる。他方、室内の空気中の塵芥量が所定値（例えば０．１ｍｇ／ｍ3）以下の場合には、送風手段４の風量が減少されるので、送風手段４のファンモーターの消費電力が軽減される。 The control unit 19 shown in FIG. 1 controls the air volume of the blower means 4 to be large or small according to the amount of dust in the indoor air measured by the dust sensor 30. That is, when the amount of dust in the indoor air is larger than a predetermined value (for example, 0.1 mg / m3 specified as a reference value for ventilation in the school hygiene management manual), the air volume of the ventilation means 4 is increased. Since a large amount of indoor air is supplied to the water surface 2a of the washing water 2, the amount of dust in the indoor air can be quickly reduced. On the other hand, when the amount of dust in the air in the room is less than a predetermined value (for example, 0.1 mg / m3), the air volume of the blower means 4 is reduced, so that the power consumption of the fan motor of the blower means 4 is reduced. ..

図１に示す制御部１９は、ダストセンサー３０で測定された室内空気中の塵芥量の大小に応じて回転手段６の回転速度を速遅と制御する。すなわち、室内の空気中の塵芥量が所定値（例えば０．１ｍｇ／ｍ3）よりも大きい場合には、回転手段６の回転速度が速まって洗浄水２の旋回流が強められ、洗浄水２の水面２ａに内部の新鮮な洗浄水２が次々と現れる循環流（矢印Ｘ）が強まるので、水面２ａにおける空気の処理効率が高まり、室内空気中の塵芥量を速やかに減少できる。他方、室内の空気中の塵芥量が所定値（例えば０．１ｍｇ／ｍ3）以下の場合には、回転手段６の回転速度が遅くなり洗浄水２の旋回流が弱められるので、回転手段のモーターの消費電力が軽減される。なお、ダストセンサー３０で測定された室内空気中の塵芥量が所定値（例えば０．１ｍｇ／ｍ3）以下の場合には、ヒーター１７の発熱を停止させ、ヒーター１７の消費電力を軽減してもよい。 The control unit 19 shown in FIG. 1 controls the rotation speed of the rotating means 6 to be fast or slow according to the amount of dust in the room air measured by the dust sensor 30. That is, when the amount of dust in the air in the room is larger than a predetermined value (for example, 0.1 mg / m3), the rotation speed of the rotating means 6 is increased, the swirling flow of the washing water 2 is strengthened, and the washing water 2 is strengthened. Since the circulating flow (arrow X) in which the fresh cleaning water 2 inside appears one after another on the water surface 2a is strengthened, the air treatment efficiency on the water surface 2a is increased, and the amount of dust in the indoor air can be quickly reduced. On the other hand, when the amount of dust in the air in the room is less than a predetermined value (for example, 0.1 mg / m3), the rotation speed of the rotating means 6 slows down and the swirling flow of the washing water 2 is weakened, so that the motor of the rotating means Power consumption is reduced. If the amount of dust in the indoor air measured by the dust sensor 30 is less than a predetermined value (for example, 0.1 mg / m3), the heat generation of the heater 17 may be stopped to reduce the power consumption of the heater 17. good.

FIG. 2 shows a water-type air purifier 1a according to a second embodiment of the present invention. The water-type air purifier 1a according to the second embodiment has substantially the same configuration as the water-type air purifier 1 of the first embodiment shown in FIG. 1, and rotates the washing water 2 in the water tank 3 around a vertical axis. Only the rotating means 6a for making the water surface 2a of the washing water 2 recess in an inverted conical shape is different. Therefore, similar parts are designated by the same reference numerals, the description thereof will be omitted, and only the differences will be described.

The water-type air purifier 1b according to the third embodiment has basically the same configuration as the water-type air purifier 1 of the first embodiment shown in FIG. The rotating means 6 that rotates around to dent the water surface 2a of the washing water 2 in an inverted conical shape is omitted, and indoor air is supplied under the horizontal water surface 2b of the non-rotating washing water 2 to expose it in water. The only difference is that it is equipped with a blower means 4b. Therefore, similar parts are designated by the same reference numerals, the description thereof will be omitted, and only the differences will be described.

図３に示すように、第３実施形態に係る水式空気清浄機1ｂにおいては、図１の第１実施形態と比べると、水槽３内の洗浄水２を鉛直軸回りに回転させて洗浄水２の水面２ａを逆円錐状に窪ませるための回転手段６が設けられておらず、送風手段４ｂの出口管１４ｂが下方に延出され、出口管１４ｂの下端開口１４ｘが水槽３内に貯留された洗浄水２の水平な水面２ｂの下方に配置されている。この構成によれば、室内の空気が洗浄水２の水中で曝気され、空気中の塵芥や有害物質（酸性物質、アルカリ性物質）が除去される。 As shown in FIG. 3, in the water-type air purifier 1b according to the third embodiment, as compared with the first embodiment of FIG. 1, the washing water 2 in the water tank 3 is rotated around the vertical axis to wash water. The rotating means 6 for denting the water surface 2a of 2 in an inverted conical shape is not provided, the outlet pipe 14b of the blowing means 4b extends downward, and the lower end opening 14x of the outlet pipe 14b is stored in the water tank 3.

In addition, since the basic operation and effect of the water-type air purifier 1b according to the third embodiment is the same as that of the water-type air purifier 1 of the first embodiment shown in FIG. 1, the description thereof will be omitted.

（第４実施形態、水式空気清浄機１ｃ）
図４に本発明の第４実施形態に係る水式空気清浄機１ｃを示す。第４実施形態に係る水式空気清浄機１ｃは、図１に示す第１実施形態の水式空気清浄機１と基本的には同様の構成であり、送風手段４ｃの出口管１４ｃが下方に延出され、その出口管（パイプ１４ｃ）の下端開口１４ｘが回転状態の洗浄水２の逆円錐状の中心の水面２ａよりも高く、静止状態の洗浄水２の水平な水面２ｂより低く設定されている点のみが相違する。よって、同様の部品には同一の符号を付して説明を省略し、相違点についてのみ説明する。 (Fourth Embodiment, water type air purifier 1c)
FIG. 4 shows a water-type air purifier 1c according to a fourth embodiment of the present invention. The water-type air purifier 1c according to the fourth embodiment has basically the same configuration as the water-type air purifier 1 of the first embodiment shown in FIG. 1, and the outlet pipe 14c of the blower means 4c is downward. The lower end opening 14x of the outlet pipe (pipe 14c) is set higher than the water surface 2a at the center of the inverted conical shape of the rotating wash water 2 and lower than the horizontal water surface 2b of the stationary wash water 2. The only difference is that. Therefore, similar parts are designated by the same reference numerals, the description thereof will be omitted, and only the differences will be described.

図４に示すように、第４実施形態に係る水式空気清浄機１ｃにおいては、図１の第１実施形態と比べると、水槽３内の洗浄水２を鉛直軸回りに回転させて洗浄水２の水面２ａを逆円錐状に窪ませる回転手段６を備えている点は同様であるが、送風手段４ｃが、回転手段６によって逆円錐状に窪んだ洗浄水２の水面２ａの中心に向けて室内の空気を供給するためのパイプ１４ｃを有し、パイプ１４ｃの下端開口１４ｘが、回転状態の洗浄水２の逆円錐状の中心の水面２ａよりも高く、静止状態の洗浄水２の水平な水面２ｂより低く設定されている点が相違する。 As shown in FIG. 4, in the water-type air purifier 1c according to the fourth embodiment, as compared with the first embodiment of FIG. 1, the washing water 2 in the water tank 3 is rotated around the vertical axis to wash water. The point that the rotating means 6 for denting the water surface 2a of 2 in an inverted conical shape is provided is the same, but the blowing means 4c is directed toward the center of the water surface 2a of the washing water 2 dented in an inverted conical shape by the rotating means 6. It has a pipe 14c for supplying indoor air, and the lower end opening 14x of the pipe 14c is higher than the water surface 2a at the center of the inverted conical shape of the rotating wash water 2, and the stationary wash water 2 is horizontal. The difference is that it is set lower than the water surface 2b.

この構成によれば、回転手段６を作動させたときには、室内の空気がパイプ１４ｃの下端開口１４ｘから逆円錐状に窪んだ洗浄水２の水面２ａの中心に吹き付けられ、回転手段６を停止させたときには、室内の空気がパイプ１４の下端開口１４ｘから洗浄水２の水平な水面２ｂの下方に供給されて水中で曝気される。空気を洗浄水２の水面２ｂ下で曝気させた場合、空気の気泡が水中で洗浄水と混合されるため（図３参照）、空気中の塵芥や有害物質（酸性物質、アルカリ性物質）が効率よく除去されるものの、気泡２５が水面２ｂで破裂する際に所謂ポコポコ音が発生する。 According to this configuration, when the rotating means 6 is operated, indoor air is blown from the lower end opening 14x of the pipe 14c to the center of the water surface 2a of the washing water 2 recessed in an inverted conical shape, and the rotating means 6 is stopped. At that time, the air in the room is supplied from the lower end opening 14x of the pipe 14 below the horizontal water surface 2b of the washing water 2 and aerated in the water. When air is aerated under the water surface 2b of the washing water 2, air bubbles are mixed with the washing water in the water (see FIG. 3), so that dust and harmful substances (acidic substances, alkaline substances) in the air are efficient. Although it is often removed, a so-called popping sound is generated when the bubbles 25 burst at the water surface 2b.

図４に示す第４実施形態に係る水式空気清浄機１ｃによれば、騒音が問題となる時間または騒音が問題となる部屋では、回転手段６で洗浄水２を回転させ、室内の空気をパイプ１４ｃの下端開口１４ｘから逆円錐状に窪んだ洗浄水２の水面２ａの中心に吹き付けることで、所謂ポコポコ音を回避できる。他方、騒音が問題とならない時間または騒音が問題とならない部屋に水式空気清浄機１ｃが移動されたときには、回転手段６を停止させ、室内の空気をパイプ１４ｃの下端開口１４ｘから洗浄水２の水平な水面２ｂの下方に供給して水中で曝気させることで（図３参照）、空気の処理効率を高めることができる。 According to the water-type air purifier 1c according to the fourth embodiment shown in FIG. 4, in the time when noise is a problem or in a room where noise is a problem, the washing water 2 is rotated by the rotating means 6 to remove the air in the room. By spraying from the lower end opening 14x of the pipe 14c to the center of the water surface 2a of the washing water 2 recessed in an inverted conical shape, so-called popping noise can be avoided. On the other hand, when the water-type air purifier 1c is moved to a room where noise is not a problem or when noise is not a problem, the rotating means 6 is stopped and the air in the room is introduced from the lower end opening 14x of the pipe 14c to the washing water 2. By supplying the air below the horizontal water surface 2b and aerating it in water (see FIG. 3), the air treatment efficiency can be improved.

図４に示す第４実施形態に係る水式空気清浄機１ｃのその他の基本的な作用効果は、図１に示す第１実施形態の水式空気清浄機１と同様であるため、説明を省略する。 Since the other basic functions of the water-type air purifier 1c according to the fourth embodiment shown in FIG. 4 are the same as those of the water-type air purifier 1 of the first embodiment shown in FIG. 1, the description thereof is omitted. do.

Therefore, it can be used in a room with dirty air. In the case of the parallel connection shown in FIG. 5B, the exhaust pipes 15 of the two water-type air purifiers 1 are assembled, and the flow rate of the air to be purified is increased as compared with that of one. Therefore, it can accommodate a large room. The same configuration is used when three or more air purifiers 1 are connected in series or in parallel. Since the basic operation and effect of these series connection and parallel connection are the same as those of the water type air purifier 1 of the first embodiment shown in FIG. 1, the description thereof will be omitted.
