（前提例１）
図１、図３、図４および図７に示すように、本体１は略箱形に形成し、本体１の天面に吹出口５を設けるとともに、本体１の前面下部に第一の吸込口２ａを設け、この第一の吸込口２ａより上部の本体１側面に第二の吸込口２ｂを設け、第一の吸込口２ａに全開、半分開口および閉鎖可能な吸込蓋部９を設けている。 (Assumption example 1)
As shown in FIGS. 1, 3, 4, and 7, the main body 1 is formed in a substantially box shape, and a blower outlet 5 is provided on the top surface of the main body 1. 2a is provided, a second suction port 2b is provided on the side of the main body 1 above the first suction port 2a, and a suction lid portion 9 that can be fully opened, half-opened and closed is provided in the first suction port 2a. .

本体１内に空気清浄化手段としてのフィルター３と、このフィルター３に通風する送風手段としてのファンモータ４を備え、ファンモータ４の駆動により吸込口２から吸い込まれた空気が、フィルター３を通って清浄され、吹出口５から吹出される。また本体１には空気中の粉塵の粒径と濃度を検出する埃センサー７を設け、制御部８は埃センサー７の検出値に対応して、吸込蓋部用駆動部１２を駆動制御することにより、吸込蓋部９を全開、半分開口または閉鎖する。また、制御部８は埃センサー７の検出値に対応して、吹出ルーバー用駆動部１１を駆動して吹出ルーバー６を回動させて、吹出口５の吹き出し方向を上方又は斜め前方に変更できるものである。 The main body 1 is provided with a filter 3 as air cleaning means and a fan motor 4 as air blowing means for passing air through the filter 3, and air sucked from the suction port 2 by driving the fan motor 4 passes through the filter 3. Then, it is cleaned and blown out from the outlet 5. Further, the main body 1 is provided with a dust sensor 7 for detecting the particle size and concentration of dust in the air, and the control unit 8 drives and controls the suction lid drive unit 12 corresponding to the detection value of the dust sensor 7. Thus, the suction lid portion 9 is fully opened, half-opened, or closed. Further, the control unit 8 can change the blowing direction of the blowout port 5 upward or obliquely forward by driving the blowout louver drive unit 11 and rotating the blowout louver 6 in response to the detection value of the dust sensor 7. Is.

埃センサー７は、検出する粉塵の粒径の大きさが１．０μｍを超えた場合と、２．５μｍを超えた場合に、各々異なる出力値を制御部８に伝達する。たとえば、検出した粉塵の粒径が２．５μｍ以上の場合は、１．０μｍを超えた場合の出力値と２．５μｍを超えた場合の出力値の２種類の出力値が出力される。このとき、一定のサンプリング時間内の出力頻度がそれぞれ基準以上のとき、制御部８は大粒径と小粒径の粉塵を検出したと判別する。それに対して、１．０μｍ〜２．５μｍの出力値の出現頻度が基準未満のときは、制御部８は大粒径の粉塵を検出したと判別する。また検出した粉塵の粒径が１．０μｍ以上２．５μｍ未満の場合は、１．０μｍを超えた場合の出力値のみが出力される。このとき、一定のサンプリング時間内の出力頻度が基準以上のときは、制御部８は小粒径の粉塵を検出したと判別する。検出した粉塵の粒径が１．０μｍ未満の場合は、ノイズを避けるため出力値を出力しない。このとき、制御部８は、粉塵を検出していないと判別する。なお表示部１３は本体１表面に設けられ、運転状態をＬＥＤと表示文字などで視覚的に表示するものである。 The dust sensor 7 transmits different output values to the control unit 8 when the particle size of the detected dust exceeds 1.0 μm and when it exceeds 2.5 μm. For example, when the particle size of the detected dust is 2.5 μm or more, two types of output values are output: an output value exceeding 1.0 μm and an output value exceeding 2.5 μm. At this time, when the output frequency within a certain sampling time is equal to or higher than the reference, the control unit 8 determines that dust having a large particle size and a small particle size has been detected. On the other hand, when the appearance frequency of the output values of 1.0 μm to 2.5 μm is less than the reference, the control unit 8 determines that dust having a large particle diameter has been detected. When the particle size of the detected dust is 1.0 μm or more and less than 2.5 μm, only the output value when it exceeds 1.0 μm is output. At this time, when the output frequency within a certain sampling time is equal to or higher than the reference, the control unit 8 determines that dust having a small particle diameter has been detected. When the particle size of the detected dust is less than 1.0 μm, no output value is output to avoid noise. At this time, the control unit 8 determines that dust is not detected. The display unit 13 is provided on the surface of the main body 1 and visually displays the operation state with LEDs and display characters.

図３に示すように、室内空気において、粒径の大きいダニの糞や死がい、花粉、埃等の粉塵は沈降しやすく室内の低域空間に多く分布し、粒径の小さいタバコの煙、ウイルス等や臭気は浮遊しやすく、室内の高域空間に多く分布することが知られている。 As shown in FIG. 3, in indoor air, ticks and dies with large particle diameters, dust such as pollen and dust are likely to settle, and are distributed in a lot of low space in the room. It is known that odors and odors are likely to float and are often distributed in indoor high-frequency spaces.

上記構成において、本体１を運転中に、制御部８は埃センサー７が大粒径の粉塵を検出したと判定する場合、または大粒径と小粒径の粉塵を検出したと判定する場合において、埃センサー７が粉塵の濃度が高いと判定するときは、吸込蓋部用駆動部１２を駆動して吸込蓋部９を全開する。これにより、低域空間空気の吸気比率の高い気流２０を形成するので、室内の低域空間に多く分布し浮遊する粒径の大きいダニの糞や死がい、花粉、埃等の粉塵を巻き込みながら、気流２０が本体１の前面下部に到達し、このように形成した循環気流２０が本体１の第一の吸込口２ａに吸引されて、フィルター３で粒径大なる汚染空気を清浄化することができる。このとき、吹出口５の吹出ルーバー６を回動して斜め前方に設定することにより、気流２０を形成しやすくなる。 In the above configuration, when the control unit 8 determines that the dust sensor 7 has detected a large particle size dust during operation of the main body 1 or when it has been determined that a large particle size and a small particle size dust have been detected. When the dust sensor 7 determines that the dust concentration is high, the suction lid drive unit 12 is driven to fully open the suction lid 9. As a result, the air flow 20 with a high intake ratio of the low-frequency space air is formed, so that mite feces and deaths with large particle diameters distributed and floating in the indoor low-frequency space are entrained, and dust such as pollen and dust is involved. The airflow 20 reaches the lower front portion of the main body 1, and the circulating airflow 20 formed in this way is sucked into the first suction port 2 a of the main body 1, and the filter 3 cleans contaminated air having a large particle size. it can. At this time, it becomes easy to form the airflow 20 by rotating the blowout louver 6 of the blowout outlet 5 and setting the blowout louver 6 diagonally forward.

また、制御部８は埃センサー７が小粒径の粉塵を検出したと判定する場合において、埃センサー７が粉塵の濃度が高いまたは低いと判定するときは、吸込蓋部用駆動部１２を駆動して吸込蓋部９を閉鎖する。これにより、高域空間空気の吸気比率の高い気流１９を形成するので、室内の高域空間に多く分布し浮遊する粒径の小さいタバコの煙、ウイルス等の粉塵を巻き込みながら、気流１９が本体１の側面に到達し、このように形成した循環気流１９が本体１の第二の吸込口２ｂに吸引されて、フィルター３で粒径小なる汚染空気を清浄化することができる。このとき、吹出口５の吹出ルーバー６を回動して上方向に設定することにより、気流１９を形成しやすくなる。 When the control unit 8 determines that the dust sensor 7 has detected a small particle size dust, when the dust sensor 7 determines that the concentration of the dust is high or low, the control unit 8 drives the suction lid drive unit 12. Then, the suction lid portion 9 is closed. As a result, an air flow 19 having a high intake ratio of the high-frequency space air is formed, so that the air flow 19 is main body while entraining dust such as cigarette smoke and viruses having a small particle size that is distributed and floats in the indoor high-frequency space. 1, the circulating airflow 19 formed in this way is sucked into the second suction port 2 b of the main body 1, and the contaminated air having a small particle diameter can be cleaned by the filter 3. At this time, the air flow 19 can be easily formed by rotating the blowout louver 6 of the blowout outlet 5 and setting it upward.

また、制御部８は埃センサー７が大粒径の粉塵を検出したと判定する場合、または大粒径と小粒径の粉塵を検出したと判定する場合において、埃センサー７が粉塵の濃度が低いと判定するときは、吸込蓋部用駆動部１２を駆動して吸込蓋部９を半分開口する。これにより、運転音の低減、消費電力を抑制しながら、通過風速を減少せずに低域空間空気の吸気比率の高い気流２０を形成するので、室内の低域空間に多く分布し浮遊する粒径の大きいダニの糞や死がい、花粉、埃等の粉塵を巻き込みながら、気流２０が本体１の前面下部に到達し、このように形成した循環気流２０が本体１の第一の吸込口２ａに吸引されて、フィルター３で粒径大なる汚染空気を清浄化することができる。 In addition, when the control unit 8 determines that the dust sensor 7 has detected a dust having a large particle size, or when it is determined that dust having a large particle size and a small particle size has been detected, the dust sensor 7 has a concentration of dust. When it determines with it being low, the suction cover part drive part 12 is driven and the suction cover part 9 is opened half way. As a result, the airflow 20 having a high intake ratio of the low-frequency space air is formed without reducing the passing wind speed while reducing the driving noise and power consumption. While entraining dust such as ticks with large diameter, dead, pollen, dust, etc., the airflow 20 reaches the lower front surface of the main body 1, and the circulating airflow 20 formed in this way enters the first suction port 2a of the main body 1. The contaminated air that has been sucked and becomes larger in particle size can be cleaned by the filter 3.

When it is determined that the detected value of the dust concentration of the dust sensor 7 is high, the suction air direction plate drive unit 16 is driven to adjust the angle of the suction air direction plate 17 to set the suction air direction from the lower side to the upper side. As a result, an air flow 20 having a high intake ratio of the low-frequency space air is easily formed, so that mite feces and dead large-sized particles that are distributed and float in the indoor low-frequency space, engulf dust such as pollen and dust.
