Further, the impeller (impeller) 230 is connected to a rotating shaft extending outward from the motor 222, and the diffuser 232 is positioned on the downstream side of the impeller 230 of the motor 222. The motor 222 is connected to an electrical connection unit and a power source, and the user can operate the blower 200 with a plurality of selection buttons 220 provided on the outer casing 218.
　上記構成で、送風装置２００は、以下のように動作する。 With the above configuration, the blower 200 operates as follows.
　ユーザが複数個の選択ボタン２２０の中から適当に選択してモータ２２２が起動されると、空気が空気入口２２４を介して送風装置２００内に吸い込まれる。空気は、外側ケーシング２１８を通り、インペラ２３０の入口２３４まで流れる。ディフューザ２３２の出口２３６及びインペラ２３０の排気部を出た空気流は、内部通路２１０を通って互いに逆の方向に進む２つの空気流に分けられる。 When the user appropriately selects from the plurality of selection buttons 220 and activates the motor 222, air is sucked into the blower 200 through the air inlet 224. Air flows through the outer casing 218 to the inlet 234 of the impeller 230. The air flow that exits the outlet 236 of the diffuser 232 and the exhaust part of the impeller 230 is divided into two air flows that travel in opposite directions through the internal passage 210.
　空気流は、口２１２に入る際に絞られ、口２１２の出口２４４で更に絞られる。この絞りにより、システム中に圧力が生じる。 The airflow is squeezed when entering the mouth 212 and further squeezed at the outlet 244 of the mouth 212. This throttling creates pressure in the system.
　このように作られた空気流は、絞りにより生じる圧力に打ち勝ち、一次空気流として出口２４４を通って出る。一次空気流は、ガイド部分２４８の配置により、ユーザに向かって集中または集束して向けられる。二次空気流は、外部環境、特に出口２４４周りの領域及び環状ノズル２０１の外縁部周りからの空気の吸引によって生じる。この二次空気流は、中央開口部２０２を通り、ここで、一次空気流と混ざり合って送風装置２００から前方に放出される全空気流が生じる。 The air flow thus created overcomes the pressure generated by the restriction and exits through the outlet 244 as the primary air flow. The primary air flow is directed or focused toward the user due to the arrangement of the guide portion 248. The secondary air flow is generated by the suction of air from the outside environment, particularly from the area around the outlet 244 and around the outer edge of the annular nozzle 201. This secondary air flow passes through the central opening 202 where there is a total air flow that mixes with the primary air flow and is released forward from the blower 200.
特開２０１０－０７７９６９号公報JP 2010-077969 A
　このような従来の送風装置２００では、一次空気流が出口２４４から出ることにより、二次空気流は外部環境、特に出口２４４周りの領域及び環状ノズル２０１の外縁部周りからの空気の吸引によって生じる。そのため、中央開口部２０２の環状ノズル２０１近傍では空気の吸引が大きく、中央開口部２０２の中心に近づくにつれ空気の吸引が小さくなる。このため、広範囲に気流を送るために環状ノズル２０１の直径を大きくすると、中央開口部２０２の中心付近の気流が小さくなり、広範囲に略均一な風速の気流を提供することができないという課題があった。 In such a conventional blower 200, the primary air flow exits from the outlet 244, so that the secondary air flow is generated by the suction of air from the external environment, particularly the area around the outlet 244 and the outer edge of the annular nozzle 201. . Therefore, the suction of air is large in the vicinity of the annular nozzle 201 of the central opening 202, and the suction of air is reduced as the center of the central opening 202 is approached. For this reason, when the diameter of the annular nozzle 201 is increased in order to send the air flow over a wide range, the air flow near the center of the central opening 202 is reduced, and there is a problem that it is not possible to provide an air flow with a substantially uniform wind speed over a wide range. It was.

　本発明に係る送風装置は、筐体に、空気を取り入れる吸込口と、高圧空気を発生するための羽根車と羽根車を駆動するためのモータで構成された高圧空気発生部と、筐体の一面から起立させた複数のノズルとを備える。また、ノズルは、側部に、ノズルを起立させた方向に対して垂直方向に高圧空気発生部で発生した高圧空気を吹出す第一吹出口を備えるとともに、内部に、高圧空気を吹出口に導くためのダクトを備える。また、ノズルは、起立させた方向に対する垂直方向の断面が吹出方向に縦長であり、複数の吹出口は同じ方向に向かって間隙を設けて備えられ、その間隙によって、吹出口から吹出す空気に誘引される空気の誘引風路が形成されている。 A blower device according to the present invention includes a suction port for taking air into a housing, an impeller for generating high-pressure air and a motor for driving the impeller, And a plurality of nozzles erected from one surface. In addition, the nozzle includes a first blow-out port that blows out high-pressure air generated by the high-pressure air generation unit in a direction perpendicular to the direction in which the nozzle is erected on the side, and the high-pressure air is provided inside the blow-out port. A duct for guiding is provided. In addition, the nozzle has a cross section perpendicular to the direction in which it stands upright in the blowing direction, and a plurality of outlets are provided with gaps in the same direction, and air is blown from the outlets by the gaps.

　また、このような従来の送風装置では、一次空気流が出口２４４から出ることにより、二次空気流は、外部環境、特に出口周りの領域及び環状ノズル２０１の外縁部周りからの空気の吸引によって生じるものであるため、気流の方向は一次空気流の方向に限定される。このため、冬場などに室内の空気を循環させるために気流を天井方向に切り替えることができないという課題があった。 Further, in such a conventional blower, the primary air flow exits from the outlet 244, so that the secondary air flow is generated by the suction of air from the external environment, particularly the area around the outlet and the outer edge of the annular nozzle 201. As it occurs, the direction of the airflow is limited to the direction of the primary airflow. For this reason, in order to circulate indoor air in winter etc., there existed a subject that an air current cannot be switched to a ceiling direction.
　本発明は、直接気流に当たることによる涼感が得られ、また、気流の吹出方向を切り替えることで、室内の空気循環を実現できる送風装置、および送風機能付空気清浄装置を提供する。 DETAILED DESCRIPTION OF THE INVENTION The present invention provides a blower device and an air cleaning device with a blower function that can obtain a cool feeling by directly hitting an airflow and can realize indoor air circulation by switching the blowing direction of the airflow.

In addition, the nozzle has a cross section perpendicular to the direction in which it stands upright in the blowing direction, and a plurality of outlets are provided with gaps in the same direction, and air is blown from the outlets by the gaps. An attracting air passage for air to be attracted is formed. Further, the nozzle includes a second air outlet that blows out high-pressure air that is opened in a direction in which the nozzle is raised at the uppermost portion of the nozzle, and includes a louver that can open and close the second air outlet.
　この構成により、直接気流に当たることによる涼感が得られ、また、ノズルを起立させた方向の気流の吹出しを加えることで、室内の空気循環を実現できる。 With this configuration, a cool feeling can be obtained by directly hitting the air flow, and indoor air circulation can be realized by adding air flow in the direction in which the nozzle is erected.
　また、本発明における送風装置は、筐体に、空気を取り入れる吸込口と、高圧空気を発生するための羽根車と羽根車を駆動するためのモータで構成された高圧空気発生部と、筐体の一面から起立させた複数のノズルとを備える。また、ノズルは、側部に、ノズルを起立させた方向に対して垂直方向に高圧空気発生部で発生した高圧空気を吹出す第一吹出口を備えるとともに、内部に、高圧空気を吹出口に導くためのダクトを備える。また、ノズルは、起立させた方向に対する垂直方向の断面が吹出方向に縦長であり、複数の吹出口は同じ方向に向かって間隙を設けて備えられ、その間隙によって、吹出口から吹出す空気に誘引される空気の誘引風路が形成されている。また、ノズルは、高圧空気を吹き出す第一吹出口と流出口とを備え、内部に第一吹出口と流出口へ高圧空気を導くためのダクトを備えた筒体であって、複数のノズルの上部に複数の流出口からの高圧空気を混合するチャンバー空間と、混合した高圧空気を吹出す第二吹出口を備える。さらに、第二吹出口をチャンバー空間の最上部でノズルを起立させた方向に開口して備え、第二吹出口を開閉可能にしたルーバーを備える。 In addition, the blower device according to the present invention includes a suction port for taking air into the casing, an impeller for generating high-pressure air, and a motor for driving the impeller, and a casing. And a plurality of nozzles erected from one surface. In addition, the nozzle includes a first blow-out port that blows out high-pressure air generated by the high-pressure air generation unit in a direction perpendicular to the direction in which the nozzle is erected on the side, and the high-pressure air is provided inside the blow-out port. A duct for guiding is provided. In addition, the nozzle has a cross section perpendicular to the direction in which it stands upright in the blowing direction, and a plurality of outlets are provided with gaps in the same direction, and air is blown from the outlets by the gaps. An attracting air passage for air to be attracted is formed. The nozzle includes a first blowout port for blowing out high-pressure air and an outflow port, and a cylindrical body including a duct for guiding high-pressure air to the first blowout port and the outflow port. A chamber space that mixes high-pressure air from a plurality of outlets and a second outlet that blows out the mixed high-pressure air are provided at the top. Furthermore, the second blower outlet is provided with an opening in the direction in which the nozzle is erected at the uppermost part of the chamber space, and a louver that allows the second blower outlet to be opened and closed is provided.
　この構成によれば、直接気流に当たることによる涼感が得られ、また、ノズルを起立させた方向の気流の吹出しを加えることで、室内の空気循環を実現できる。 According to this configuration, a cool sensation can be obtained by directly hitting the air flow, and the air circulation in the room can be realized by adding the air flow in the direction in which the nozzle is erected.
　また、このような従来の送風装置では、一次空気流が出口２４４から出ることにより、二次空気流は外部環境、特に出口周りの領域及び環状ノズル２０１の外縁部周りからの空気の吸引によって生じるものであるため、中央開口部２０２の環状ノズル２０１近傍では空気の吸引が大きく、中央開口部２０２の中心に近づくにつれ空気の吸引が小さくなるものである。このため、環状にしか空気を吹出すことができず、送風範囲を調整することができないという課題があった。 Further, in such a conventional blower, the primary air flow exits from the outlet 244, so that the secondary air flow is generated by the suction of air from the external environment, particularly the area around the outlet and the outer edge of the annular nozzle 201. Therefore, air suction is large in the vicinity of the annular nozzle 201 in the central opening 202, and air suction is reduced as the center of the central opening 202 is approached. For this reason, there existed a subject that air could be blown out only in cyclic | annular form and the ventilation range could not be adjusted.
　そこで本発明は、吹出口からの高圧空気の吹出しにより誘引される空気の送風範囲を調整できる送風装置を提供する。 Therefore, the present invention provides a blower capable of adjusting the air blowing range attracted by the high pressure air blown from the blower outlet.

　本実施の形態における送風装置である送風機能付空気清浄装置１１は、図１に示すように筐体１２の上部に複数のノズル１３を備えている。 The air purifier 11 with an air blowing function, which is an air blowing device in the present embodiment, includes a plurality of nozzles 13 at the top of a housing 12 as shown in FIG.
　送風機能付空気清浄装置１１は、図２に示すように、筐体１２に空気を取り入れる吸込口１４と、吸込口１４に装着し取り入れた空気を浄化する空気浄化フィルタ１５を備える。また、送風機能付空気清浄装置１１は、図３に示すように、高圧空気を発生するための羽根車１６と羽根車１６を駆動するためのモータ１７で構成された高圧空気発生部１８と、筐体１２の一面から起立させた複数の、等しい長さのノズル１３を備えている。本実施の形態では、ノズル１３は筐体１２の上面から起立している。なお、本実施の形態においては、ノズル１３は６個設けている。 As shown in FIG. 2, the air purification device 11 with a blowing function includes a suction port 14 that takes air into the housing 12 and an air purification filter 15 that purifies the air that is attached to the suction port 14 and taken in. Further, as shown in FIG. 3, the air purifier 11 with a blowing function includes an impeller 16 for generating high-pressure air and a high-pressure air generator 18 configured by a motor 17 for driving the impeller 16, A plurality of nozzles 13 having the same length are provided from one surface of the housing 12. In the present embodiment, the nozzle 13 stands from the upper surface of the housing 12. In the present embodiment, six nozzles 13 are provided.
　ノズル１３の側部には、図２に示すように、ノズル１３を起立させた方向に対して垂直方向である一方向に高圧空気発生部１８（図３参照）で発生した高圧空気を吹出す第一吹出口である吹出口１９を備えている。ノズル１３の内部には、高圧空気を吹出口１９に導くためのダクト２０を備えている。ダクト２０は、それぞれのノズル１３に少なくともひとつ備えている。 As shown in FIG. 2, high-pressure air generated by the high-pressure air generator 18 (see FIG. 3) is blown out to the side of the nozzle 13 in one direction perpendicular to the direction in which the nozzle 13 is erected. The blower outlet 19 which is a 1st blower outlet is provided. Inside the nozzle 13, a duct 20 for guiding the high-pressure air to the outlet 19 is provided. At least one duct 20 is provided for each nozzle 13.
　また、図３に示すように、高圧空気発生部１８と複数のダクト２０の間には高圧空気を各ノズルに分流するチャンバー空間２１が備えられている。 Further, as shown in FIG. 3, a chamber space 21 is provided between the high-pressure air generator 18 and the plurality of ducts 20 to divide the high-pressure air to each nozzle.
　ノズル１３は、図４に示すように、起立させた方向に対する垂直方向の断面が吹出方向に縦長である。複数のノズル１３は、それぞれの吹出口１９が同一面となるように間隙を設けて備えられ、この間隙によって、吹出口１９から吹出す気流に誘引される空気の誘引風路２２が形成されている。つまり、本実施の形態の例ではノズル１３を６本設けているので、ノズル１３に挟まれた空隙にそれぞれ誘引風路２２がノズル１３の数より少ない５本形成できる。なお、誘引風路２２を形成するための間隙の長さとしては、ノズル１３の起立させた方向に対する垂直方向の断面における吹出方向に対して垂直方向の長さ（ノズル１３の幅）以上であって、ノズル１３の筐体１２上面からの起立方向の長さの半分以下であるのが風速の均一性を得られるため好ましい。本実施の形態では、一例としてノズル１３の幅が３０ｍｍ、ノズル１３の起立方向長さが６００ｍｍ、間隙の長さが１００ｍｍ、ノズル１３の吹出方向長さが２００ｍｍの場合を示している。また本実施の形態では、ノズル１３の垂直方向の断面形状を長方形としたが、吹出し方向に縦長であればよく、楕円など別の形状でもよい。また、図２に示した空気浄化フィルタ１５には、既知の集塵フィルタや活性炭などの脱臭フィルタを用いることができる。この空気浄化フィルタ１５を通過した空気は、ほこりや花粉、アレルギー物質などが取り除かれた浄化空気となり羽根車１６に供給される。 As shown in FIG. 4, the nozzle 13 has a vertically long section in the blowing direction with respect to the vertical direction. The plurality of nozzles 13 are provided with gaps so that the air outlets 19 are flush with each other, and an air induction air passage 22 that is attracted by the airflow blown from the air outlets 19 is formed by the gaps. Yes. That is, in the example of the present embodiment, since six nozzles 13 are provided, five induction air passages 22 that are smaller than the number of nozzles 13 can be formed in the gaps sandwiched between the nozzles 13, respectively. The length of the gap for forming the induction air passage 22 is not less than the length in the direction perpendicular to the blowing direction (width of the nozzle 13) in the cross section perpendicular to the direction in which the nozzle 13 is erected. Thus, it is preferable that the length of the nozzle 13 is not more than half the length in the standing direction from the upper surface of the housing 12 because the uniformity of the wind speed can be obtained. In the present embodiment, as an example, the case where the width of the nozzle 13 is 30 mm, the length of the nozzle 13 in the standing direction is 600 mm, the length of the gap is 100 mm, and the length of the nozzle 13 in the blowing direction is 200 mm. In the present embodiment, the cross-sectional shape in the vertical direction of the nozzle 13 is rectangular, but it may be vertically long in the blowing direction, and may be another shape such as an ellipse. Further, as the air purification filter 15 shown in FIG. 2, a known deodorizing filter such as a dust collection filter or activated carbon can be used. The air that has passed through the air purification filter 15 is supplied to the impeller 16 as purified air from which dust, pollen, allergens, and the like have been removed.
　また、複数のノズル１３は、図４に示すように、筐体１２の中央から外側に設けられたノズル１３に向かうにつれて、中央のノズル１３に対して空気の吹出し方向が離れていくように広角に備えられている。 Further, as shown in FIG. 4, the plurality of nozzles 13 have a wide angle so that the air blowing direction is away from the central nozzle 13 as it goes from the center of the housing 12 to the nozzle 13 provided outside. Is provided.
　図２に示すように、ノズル１３内の吹出口１９の近傍にはノズル１３の起立方向の風向を調整する風向調整リブ２４が備えられている。ここで、複数のノズル１３とはノズル１３が３本以上あることを示す。また、風速の均一性とは後述する吹出空気流２５と誘引空気流２６（図１参照）が合流した面気流の風速の分布に着目したもので、吹出口１９から所定の距離を離れて正面視する平面において観測される風速の分布が、所定の範囲であることを示す。つまり平面での最小の風速が少なくとも最大風速の半分までは許容できることとしている。また、高圧空気とは大気圧以上の空気を示すものとする。 As shown in FIG. 2, a wind direction adjusting rib 24 for adjusting the wind direction in the standing direction of the nozzle 13 is provided in the vicinity of the air outlet 19 in the nozzle 13. Here, the plurality of nozzles 13 indicates that there are three or more nozzles 13. Further, the uniformity of the wind speed is focused on the distribution of the wind speed of the surface airflow in which the blown air flow 25 and the induced air flow 26 (see FIG. 1), which will be described later, are joined. It shows that the distribution of wind speed observed on the viewing plane is within a predetermined range. In other words, the minimum wind speed on the plane is allowed to be at least half of the maximum wind speed. Moreover, high pressure air shall show the air above atmospheric pressure.
　このような構成によれば、送風機能付空気清浄装置１１が稼動すると、高圧空気発生部１８を構成するモータ１７が駆動し、羽根車１６が回転することにより、室内空気は、内部流れ２３に示すように流れる。すなわち、室内空気は、吸込口１４から送風機能付空気清浄装置１１内部に取り込まれ、空気浄化フィルタ１５で埃やにおいなどの汚れを浄化された後、羽根車１６を通過しチャンバー空間２１に至る。高圧空気は、チャンバー空間２１で複数のノズル１３のダクト２０に分流され、それぞれのダクト２０を通過し、吹出口１９近傍に設けられた風向調整リブ２４でノズル１３の起立方向の風向を調整され、吹出口１９から吹出し、吹出空気流２５となる。 According to such a configuration, when the air cleaning device 11 with the air blowing function is operated, the motor 17 constituting the high-pressure air generation unit 18 is driven and the impeller 16 rotates, so that the indoor air flows into the internal flow 23. It flows as shown. That is, the indoor air is taken into the air purifier 11 with a blowing function from the suction port 14, and after dirt such as dust and smell is purified by the air purification filter 15, the room air passes through the impeller 16 and reaches the chamber space 21. . The high-pressure air is divided into the ducts 20 of the plurality of nozzles 13 in the chamber space 21, passes through the respective ducts 20, and the wind direction in the standing direction of the nozzles 13 is adjusted by the wind direction adjusting ribs 24 provided in the vicinity of the air outlet 19. The air is blown out from the air outlet 19 to become a blown air flow 25.
　そして、図１のように吹出空気流２５により、隣り合うノズル１３の間に形成されている誘引風路２２と最外部のノズル１３の外側の空気が誘引され、誘引空気流２６となる。これら吹出空気流２５と誘引空気流２６が送風機能付空気清浄装置１１の吹出方向前方で合流し、広範囲に略均一な風速の浄化された空気の面気流を送風できる。このとき、羽根車１６は筐体１２内に内包されているため、使用者が外部から接触できない構造となっているため、接触による不安感をなくすことができる。 Then, as shown in FIG. 1, the air flow 25 formed between the adjacent nozzles 13 and the air outside the outermost nozzle 13 are attracted by the blown air flow 25, thereby forming an induced air flow 26. The blown air flow 25 and the induced air flow 26 are merged in front of the blowing direction of the air cleaning device 11 with the blowing function, and the surface airflow of the purified air having a substantially uniform wind speed can be blown over a wide range. At this time, since the impeller 16 is included in the housing 12, the user cannot make contact from the outside, so that anxiety due to contact can be eliminated.
　また、吹出口１９が同じ方向に向かうように間隙を設けてノズル１３を配置することで、吹出す気流は面気流となる。 Further, by arranging the nozzle 13 with a gap so that the air outlet 19 is directed in the same direction, the airflow to be blown becomes a surface airflow.
　面気流は、広範囲に略均一な風速の気流で、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成される。よって、直進性に優れ、風速の減衰が少なく遠方まで到達することができる。 The surface airflow is an airflow with a substantially uniform wind speed over a wide area, and is a straight airflow in the blowing direction, so that a core region is formed at the center of the surface airflow. Therefore, it is excellent in straightness and can reach far away with little attenuation of wind speed.
　また、面気流は広範囲に略均一な風速の気流で、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成される。つまり、遠方に向かうにつれ中心部の風速が大きくなる風速分布となることもある。このため、図４に示すように、筐体１２中央から外側に設けられたノズル１３に向かうにつれて、中央のノズル１３に対して空気の吹出し方向が離れていくようにノズル１３を広角に備えることで中心部に気流が集まるのを抑制できる。これにより、より遠方まで略均一な風速の気流を送ることができる。 Also, the surface airflow is an airflow with a substantially uniform wind speed over a wide area and is a straight airflow in the blowing direction, so that a core region is formed at the center of the surface airflow. In other words, the wind speed distribution may increase as the wind speed increases in the center as it travels farther away. Therefore, as shown in FIG. 4, the nozzle 13 is provided at a wide angle so that the air blowing direction is away from the central nozzle 13 from the center of the housing 12 toward the nozzle 13 provided on the outside. It is possible to suppress airflow from being collected at the center. Thereby, the airflow of a substantially uniform wind speed can be sent farther.
　また、風向調整リブ２４は仰角を調整することでノズル１３の起立方向の風向を広げることができるため、ノズル１３の起立方向長さより広範囲に送風することができる。すなわち、送風機能付空気清浄装置１１の高さよりも上方にも送風することができる。 Also, since the wind direction adjusting rib 24 can widen the wind direction in the standing direction of the nozzle 13 by adjusting the elevation angle, the air can be blown in a wider range than the length in the standing direction of the nozzle 13. In other words, the air can be blown above the height of the air purifier 11 with a blowing function.
　なお、本実施の形態では、空気浄化フィルタ１５を備えた送風機能付空気清浄装置１１の形態を説明したが、送風装置としては、空気浄化フィルタ１５は必須ではない。 In addition, in this Embodiment, although the form of the air purification apparatus 11 with a ventilation function provided with the air purification filter 15 was demonstrated, the air purification filter 15 is not essential as a ventilation apparatus.

　図５に本発明の第２の実施の形態における送風装置３１の斜視図を示す。なお、第１の実施の形態と同様の構成要素については同一の符号を付し、その詳細な説明は省略する。送風装置３１は、図１と同様な複数のノズル１３の上部を天板３２で繋いでおり、複数の誘引風路２２がそれぞれ独立した構成となっている。 (Second Embodiment)
FIG. 5 shows a perspective view of the blower 31 in the second embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the component similar to 1st Embodiment, and the detailed description is abbreviate | omitted. The air blower 31 connects the upper part of the some nozzle 13 similar to FIG. 1 with the top plate 32, and the some induction | guidance | derivation wind path 22 has become the respectively independent structure.
　このような構成によれば、天板３２によりノズル１３の上方からの気流の侵入を防止できるので、外乱の影響を受けることがないため、安定して面気流を発生させることができる。そのため、送風装置３１は羽根車１６を筐体１２で内包することで使用者の接触による不安感をなくしつつ、広範囲に略均一な風速の気流を提供することができる。なおノズル１３の上方からの気流としては、室内に設置した空気調和装置の吹出し空気等が想定される。 According to such a configuration, since the intrusion of the airflow from above the nozzle 13 can be prevented by the top plate 32, the surface airflow can be stably generated because it is not affected by the disturbance. Therefore, the air blower 31 can provide an air flow with a substantially uniform wind speed over a wide range while eliminating the anxiety caused by the user's contact by including the impeller 16 in the housing 12. Note that the airflow from above the nozzle 13 is assumed to be air blown from an air conditioner installed indoors.
　また、面気流は広範囲に略均一な風速の気流で、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成されるため直進性に優れ、風速の減衰が少なく遠方まで到達することができる。 In addition, the surface airflow is an airflow with a substantially uniform wind speed over a wide area, and since the airflow is straight in the blowing direction, the core area is formed in the center of the surface airflow, so it is excellent in straightness, with little attenuation of the wind speed and far away Can be reached.
　なお、本実施の形態の送風装置３１は、吸込口１４に取り入れた空気を浄化する図２に示す空気浄化フィルタ１５を装着することで送風機能付空気清浄装置とすることもできる。 In addition, the air blower 31 of this Embodiment can also be set as the air purifier with a ventilation function by mounting | wearing the air purification filter 15 shown in FIG. 2 which purifies the air taken in into the suction inlet 14.

FIG. 6 shows a perspective view of the blower 41 in the third embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the component similar to 1st Embodiment, and the detailed description is abbreviate | omitted. The blower 41 may be placed on the floor 43 with the surface of the housing 12 opposite to the air outlet 19 in contact with the indoor wall 42.
　送風装置３１の複数のノズル１３は、既に第１の実施の形態で説明したダクト２０の風路断面とともに、ノズル１３を起立させた先端に向かうにつれて吹出口１９側に断面を小さくして備えている。 The plurality of nozzles 13 of the blower device 31 are provided with a cross-section that is made smaller toward the outlet 19 side toward the tip where the nozzle 13 is erected together with the air path cross section of the duct 20 already described in the first embodiment. Yes.
　このような構成によれば、室内壁４２に接して置かれている状態でもノズル１３の上部と室内壁４２の間に隙間を設けることができるため、誘引風路２２に誘引空気流２６を導くことができ、面気流を発生させることができる。そのため、羽根車１６を筐体１２の内包することで使用者の接触による不安感をなくしつつ、広範囲に略均一な風速の気流を提供することができるとともに、部屋を広く有効に使うことができる。 According to such a configuration, a gap can be provided between the upper portion of the nozzle 13 and the indoor wall 42 even in a state of being placed in contact with the indoor wall 42, so that the induced air flow 26 is guided to the induced air path 22. And can generate a surface airflow. Therefore, by enclosing the impeller 16 in the housing 12, it is possible to provide a substantially uniform air velocity in a wide range and eliminate the anxiety caused by the user's contact, and to use the room widely and effectively. .
　また、ノズル１３を起立させた先端に向かうにつれて、ダクト２０の風路断面を小さくすることで、ノズル１３を起立させた先端に向かうにつれてダクト２０の内部静圧が低下するのを抑制することができ、吹出口１９から吹出す高圧空気の風速をノズル１３の起立方向に対して均一化でき、広範囲に略均一な風速の面気流を提供することができる。 Moreover, it can suppress that the internal static pressure of the duct 20 falls as it goes to the front-end | tip which raised the nozzle 13 by making the air path cross section of the duct 20 small as it goes to the front-end | tip which raised the nozzle 13. FIG. In addition, the wind speed of the high-pressure air blown from the outlet 19 can be made uniform with respect to the rising direction of the nozzle 13, and a surface airflow having a substantially uniform wind speed can be provided over a wide range.

　（第４の実施の形態）
　以上、第１の実施の形態から第３の実施の形態において、送風機能付空気清浄装置１１、送風装置３１、送風装置４１を説明した。本実施の形態では、これらを総称して、送風装置５１として、家屋に設置した場合の形態を説明する。 (Fourth embodiment)
As described above, in the first embodiment to the third embodiment, the air cleaning device 11 with the air blowing function, the air blowing device 31, and the air blowing device 41 have been described. In this Embodiment, these are named generically and the form at the time of installing in a house as the air blower 51 is demonstrated.
　図７に本発明の第４の実施の形態における送風装置５１を備えた家屋の部分断面を示す構成図を示す。なお、第１の実施の形態と同様の構成要素については同一の符号を付し、その詳細な説明は省略する。送風装置５１は家屋の一階５２と二階５３を連通する吹抜け５４に、吹出口１９を一階５２の方向に向けて複数のノズル１３を備え、筐体１２（図示しない）を一階天井５５と二階床５６の間の空間に備え、吸込口２７を一階天井５５に備えた構成となっている。 FIG. 7 shows a configuration diagram showing a partial cross section of a house provided with a blower device 51 according to a fourth embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the component similar to 1st Embodiment, and the detailed description is abbreviate | omitted. The blower 51 is provided with a plurality of nozzles 13 in a blow-out 54 communicating with the first floor 52 and the second floor 53 of the house, with the air outlet 19 directed toward the first floor 52, and the casing 12 (not shown) is mounted on the first floor ceiling 55. The first floor ceiling 55 is provided with a suction port 27 in the space between the first floor 56 and the second floor 56.
　このような構成によれば、送風装置５１を稼動させることにより、一階５２の一階天井５５付近の空気が吸込口２７から取り込まれ、吹出口１９から吹出すことにより吹出空気流２５が発生する。これにより吹抜け５４の上方の二階５３の空気を一階５２に向けて誘引空気流２６として誘引風路２２を通り一階５２に送ることができる。このとき、一階５２の空気の吹出空気流２５と二階５３の空気の誘引空気流２６が混ざり合うため、効率よく室内の空気を攪拌することができる。特に夏季や冬季の冷暖房器具使用時には一階５２と二階５３の温度差を効率よく解消（サーキュレーション効果）することができる。また、羽根車１６を筐体１２（図７には図示せず）で内包しているため、回転体が見えることによる圧迫感を使用者に与えることなく、面気流による涼感やサーキュレーション効果を提供することができる。 According to such a configuration, when the air blower 51 is operated, the air near the first floor ceiling 55 of the first floor 52 is taken in from the suction port 27 and blown out from the blowout port 19 to generate the blown air flow 25. To do. As a result, the air on the second floor 53 above the blow-out 54 can be sent to the first floor 52 through the induction air passage 22 as the induced air flow 26 toward the first floor 52. At this time, since the blown air flow 25 of the air on the first floor 52 and the induced air flow 26 of the air on the second floor 53 are mixed, the indoor air can be efficiently stirred. In particular, the temperature difference between the first floor 52 and the second floor 53 can be efficiently eliminated (circulation effect) when the air conditioner is used in summer or winter. In addition, since the impeller 16 is included in the housing 12 (not shown in FIG. 7), a cool feeling and a circulation effect due to the surface airflow are provided without giving the user a feeling of pressure due to the view of the rotating body. Can be provided.
　なお、本実施の形態の送風装置５１は、吸込口１４（図７には図示せず）に取り入れた空気を浄化する、図２に示す空気浄化フィルタ１５を装着することで送風機能付空気清浄装置とすることもできる。 In addition, the air blower 51 of this Embodiment purify | cleans the air taken in in the suction inlet 14 (not shown in FIG. 7), and is equipped with the air purification filter 15 shown in FIG. It can also be a device.
　（第５の実施の形態）
　図８は本発明の第５の実施の形態における送風装置である送風機能付空気清浄装置６１の斜視図である。以下、図８から図１２を参照しながら、送風機能付空気清浄装置６１について説明する。 (Fifth embodiment)
FIG. 8 is a perspective view of an air cleaning device 61 with an air blowing function which is an air blowing device according to a fifth embodiment of the present invention. Hereinafter, the air cleaning device 61 with a blowing function will be described with reference to FIGS. 8 to 12.
　送風機能付空気清浄装置６１は、図８に示すように、筐体１２の上部に複数のノズル６３を備え、ノズル６３の最上部（ノズル６３の天面）に第二吹出口７７を備えている。さらに、ルーバー７８を備え、ルーバー７８の回動によって第二吹出口７７を開閉する。 As shown in FIG. 8, the air cleaning device 61 with a blowing function includes a plurality of nozzles 63 at the top of the housing 12, and a second air outlet 77 at the top of the nozzle 63 (the top surface of the nozzle 63). Yes. Further, a louver 78 is provided, and the second outlet 77 is opened and closed by the rotation of the louver 78.
　ノズル６３は、筐体１２の一面から複数（本実施の形態では６個）起立させているとともに、それぞれのノズル６３の長さは等しい。なお、複数のノズル６３とは３本以上のノズル６３のことを示す。 A plurality of nozzles 63 (six in this embodiment) are erected from one surface of the housing 12, and the lengths of the nozzles 63 are equal. The plurality of nozzles 63 indicate three or more nozzles 63.
　また、後述する第一吹出口６９は、図１に示す第１の実施の形態の吹出口１９と同一のものである。本実施の形態の第二吹出口７７と区別をするために別の符号を付している。 Further, a first air outlet 69 to be described later is the same as the air outlet 19 of the first embodiment shown in FIG. In order to distinguish from the 2nd blower outlet 77 of this Embodiment, another code | symbol is attached | subjected.
　送風機能付空気清浄装置６１は、図８の断面Ｄである図９に示す、筐体１２に空気を取り入れる吸込口１４と、吸込口１４に装着し取り入れた空気を浄化する空気浄化フィルタ１５と、図８の断面Ｅである図１０に示す、高圧空気を発生するための羽根車１６と羽根車１６を駆動するためのモータ１７とで構成された高圧空気発生部１８を備えている。 The air purification device 61 with a blowing function includes a suction port 14 for taking air into the housing 12 and an air purification filter 15 for purifying the air that is attached to the suction port 14 and shown in FIG. 10 includes a high-pressure air generator 18 that includes an impeller 16 for generating high-pressure air and a motor 17 for driving the impeller 16 shown in FIG.
　ノズル６３の側部には、図９に示すように、ノズル６３を起立させた方向に対して垂直方向（図９の左方向）である一方向に高圧空気発生部１８で発生した高圧空気を吹出す第一吹出口６９を備えている。ノズル６３の内部には、高圧空気を第一吹出口６９に導くためのダクト２０を備えている。ダクト２０は、少なくともノズル６３内に一つ備えている。 As shown in FIG. 9, high-pressure air generated by the high-pressure air generator 18 in one direction that is perpendicular to the direction in which the nozzle 63 is erected (leftward in FIG. 9) is formed on the side of the nozzle 63. A first air outlet 69 is provided. Inside the nozzle 63, a duct 20 for guiding high-pressure air to the first air outlet 69 is provided. At least one duct 20 is provided in the nozzle 63.
　また、図９、図１０に示すように、高圧空気発生部１８と複数のダクト２０の間には高圧空気を各ノズルに分流するチャンバー空間２１が備えられている。 Also, as shown in FIGS. 9 and 10, a chamber space 21 is provided between the high-pressure air generator 18 and the plurality of ducts 20 to divide the high-pressure air to each nozzle.
　ノズル６３は、起立方向に対して垂直方向に切った断面が吹出方向に縦長である。 The cross section of the nozzle 63 cut in the direction perpendicular to the standing direction is vertically long in the blowing direction.
　図８に示すように、複数のノズル６３は、それぞれの第一吹出口６９が同じ方向を向くように、間隙を設けて備えられている。そして、この間隙によって、第一吹出口６９から吹出す気流に誘引される空気の誘引風路２２が形成されている。本実施の形態の例ではノズル６３を６本設けているので、隣り合ったノズル６３に挟まれた間隙にそれぞれ誘引風路２２がノズル６３の数より少ない５本形成できる。なお、間隙の長さとしては、ノズル６３の起立させた方法に対する垂直方向の断面における吹出方向に対して垂直方向の長さ（ノズル６３の幅）以上、ノズル６３の筐体１２上面からの起立方向の長さの半分以下が風速の均一性を得られるため好ましい。本実施の形態では、一例としてノズル６３の幅が３０ｍｍ、ノズル６３の起立方向長さが６００ｍｍ、隣り合うノズル６３の間の間隙の幅が１００ｍｍ、ノズル６３の吹出方向長さが２００ｍｍの場合を示している。 As shown in FIG. 8, the plurality of nozzles 63 are provided with gaps so that the first air outlets 69 face the same direction. In addition, an air pulling air passage 22 that is attracted by the airflow blown from the first air outlet 69 is formed by the gap. In the example of the present embodiment, since six nozzles 63 are provided, five induction air passages 22 each having a number smaller than the number of nozzles 63 can be formed in the gap between the adjacent nozzles 63. The length of the gap is equal to or longer than the length in the vertical direction (width of the nozzle 63) with respect to the blowing direction in the vertical cross section of the method in which the nozzle 63 is erected, and the nozzle 63 is erected from the upper surface of the casing 12. Less than half of the length in the direction is preferable because uniformity of wind speed can be obtained. In this embodiment, as an example, the case where the width of the nozzle 63 is 30 mm, the length of the nozzle 63 in the standing direction is 600 mm, the width of the gap between the adjacent nozzles 63 is 100 mm, and the length of the nozzle 63 in the blowing direction is 200 mm. Show.
　図９に示すように、ノズル６３内の第一吹出口６９近傍には、ノズル６３の起立方向の気流を直角方向で仰角を調整する風向調整リブ２４が備えられている。 As shown in FIG. 9, a wind direction adjusting rib 24 that adjusts the elevation angle of the airflow in the standing direction of the nozzle 63 in a perpendicular direction is provided in the vicinity of the first outlet 69 in the nozzle 63.
　また、送風機能付空気清浄装置６１は、図１１に示すように、ノズル６３の最上部（ノズル６３の天面）に設けられているルーバー７８を、回転軸７６を軸に回転させてノズル６３の上部の第二吹出口７７を開放することができる。 In addition, as shown in FIG. 11, the air cleaning device 61 with a blowing function rotates the louver 78 provided on the uppermost part of the nozzle 63 (the top surface of the nozzle 63) around the rotation shaft 76, so that the nozzle 63. The second air outlet 77 at the top of the can be opened.
　また、複数の第二吹出口７７の開口面積の合計が、複数のノズル６３の第一吹出口６９の開口面積の合計より大きく備えられている。 Further, the sum of the opening areas of the plurality of second outlets 77 is larger than the sum of the opening areas of the first outlets 69 of the plurality of nozzles 63.
　また、複数のノズル６３は、筐体１２の中央から外側に設けられたノズル６３に向かうにつれて、中央のノズル６３に対して空気の吹出し方向が離れていくように広角に備えられている。 Further, the plurality of nozzles 63 are provided at a wide angle so that the air blowing direction is away from the central nozzle 63 as it goes from the center of the housing 12 to the nozzle 63 provided outside.
　このような構成によれば、ルーバー７８を閉じた状態では、送風機能付空気清浄装置６１が稼動すると、モータ１７が駆動し、羽根車１６が回転することにより、図９に示す内部流れ２３が発生する。そして、室内空気は、吸込口１４から送風機能付空気清浄装置６１内部に取り込まれ、空気浄化フィルタ１５で埃やにおいなどの汚れを浄化された後、羽根車１６を通過しチャンバー空間２１に至る。チャンバー空間２１で高圧空気は複数のダクト２０に分流され、それぞれのダクト２０を通過し、第一吹出口６９近傍に設けられた風向調整リブ２４でノズル１３起立方向の風向を調整され、第一吹出口６９から吹出し、吹出空気流２５となる。 According to such a configuration, in a state where the louver 78 is closed, when the air cleaning device 61 with a blowing function is operated, the motor 17 is driven and the impeller 16 rotates, so that the internal flow 23 shown in FIG. appear. The room air is taken into the air cleaning device 61 with a blowing function from the suction port 14, and after dirt such as dust and smell is purified by the air purification filter 15, the room air passes through the impeller 16 and reaches the chamber space 21. . In the chamber space 21, the high-pressure air is divided into a plurality of ducts 20, passes through the respective ducts 20, and the wind direction in the standing direction of the nozzle 13 is adjusted by the wind direction adjusting ribs 24 provided in the vicinity of the first outlet 69. It blows out from the blower outlet 69, and becomes the blown air flow 25.
　つまり、図８のように吹出空気流２５により、誘引風路２２と最外部のノズル６３の外側の空気が誘引され、誘引空気流２６となる。これら吹出空気流２５と誘引空気流２６が送風機能付空気清浄装置６１の吹出方向前方で合流し、広範囲に略均一な風速の浄化された空気の面気流を送風できる。このとき、羽根車１６は筐体１２内に内包されているため、使用者が外部から接触できない構造となっているため、接触による不安感をなくすことができる。 That is, as shown in FIG. 8, the blown air flow 25 attracts air outside the induced air passage 22 and the outermost nozzle 63, resulting in an induced air flow 26. The blown air flow 25 and the induced air flow 26 are merged in front of the blowing direction of the air cleaning device 61 with a blowing function, and the surface airflow of the purified air having a substantially uniform wind speed can be blown over a wide range. At this time, since the impeller 16 is included in the housing 12, the user cannot make contact from the outside, so that anxiety due to contact can be eliminated.
　また、第一吹出口６９が同じ方向に向かうようにノズル１３を、間隙を設けて配置することで、吹出す気流は面気流となる。 Also, the air flow to be blown out becomes a surface air flow by arranging the nozzle 13 with a gap so that the first air outlet 69 is directed in the same direction.
　面気流は、広範囲に略均一な風速の気流で、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成される。よって、直進性に優れ、風速の減衰が少なく遠方まで到達することができる。 The surface airflow is an airflow with a substantially uniform wind speed over a wide area, and is a straight airflow in the blowing direction, so that a core region is formed at the center of the surface airflow. Therefore, it is excellent in straightness and can reach far away with little attenuation of wind speed.
　また、面気流は広範囲に略均一な風速の気流で、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成される。つまり、遠方に向かうにつれ中心部の風速が大きくなる風速分布となることもある。このため、ノズル６３は、筐体１２中央から外側に設けられたノズル６３に向かうにつれて、中央のノズル６３に対して空気の吹出し方向が離れていくように広角に備えることで中心部に気流が集まるのを抑制できる。これにより、より遠方まで略均一な風速の気流を送ることができる。 Also, the surface airflow is an airflow with a substantially uniform wind speed over a wide area and is a straight airflow in the blowing direction, so that a core region is formed at the center of the surface airflow. In other words, the wind speed distribution may increase as the wind speed increases in the center as it travels farther away. For this reason, the nozzle 63 is provided at a wide angle so that the air blowing direction is away from the central nozzle 63 as it goes from the center of the housing 12 to the nozzle 63 provided on the outer side, so that airflow is generated at the center. It can suppress gathering. Thereby, the airflow of a substantially uniform wind speed can be sent farther.
　また、風向調整リブ２４を備えて仰角を調整することでノズル６３の起立方向の風向を広げることができるため、ノズル６３の起立方向長さより広範囲に送風することができる。すなわち、送風機能付空気清浄装置６１高さよりも上方にも送風することができる。 Further, since the wind direction in the standing direction of the nozzle 63 can be widened by providing the wind direction adjusting rib 24 and adjusting the elevation angle, the air can be blown in a wider range than the length of the nozzle 63 in the standing direction. In other words, the air can be blown above the height of the air purifier 61 with the blow function.
　また、ルーバー７８を開けた状態で、送風機能付空気清浄装置６１が稼動すると、モータ１７が駆動し、羽根車１６が回転することにより、図１１（後述する図１２における断面Ｆ）に示す内部流れ２３が発生する。室内空気は、吸込口１４から送風機能付空気清浄装置６１内部に取り込まれ、空気浄化フィルタ１５で埃やにおいなどの汚れを浄化された後、羽根車１６を通過しチャンバー空間２１に至る。高圧空気は、チャンバー空間２１で複数のダクト２０に分流され、それぞれのダクト２０を通過し、一部の高圧空気は、第一吹出口６９近傍に設けられた風向調整リブ２４の作用によってノズル６３の起立方向の風向を調整され、第一吹出口６９から吹出し、吹出空気流２５となる。しかし、大部分の高圧空気は、第二吹出口７７から吹出し、上方への吹出空気流３５となる。なお、大部分の高圧空気とは、全高圧空気量の６割以上のことを示す。 Further, when the air cleaning device 61 with the air blowing function is operated with the louver 78 opened, the motor 17 is driven and the impeller 16 rotates, thereby causing the interior shown in FIG. 11 (cross section F in FIG. 12 described later). Stream 23 is generated. The room air is taken into the air purifying device 61 with a blowing function from the suction port 14, and dirt such as dust and smell is purified by the air purification filter 15, and then passes through the impeller 16 and reaches the chamber space 21. The high-pressure air is divided into a plurality of ducts 20 in the chamber space 21 and passes through the respective ducts 20, and a part of the high-pressure air is nozzle 63 by the action of the wind direction adjusting rib 24 provided in the vicinity of the first air outlet 69. The wind direction in the standing direction is adjusted and blown out from the first air outlet 69 to become a blown air flow 25. However, most of the high-pressure air is blown out from the second blow-out opening 77 and becomes a blow-out air flow 35 upward. Note that the majority of high-pressure air indicates 60% or more of the total amount of high-pressure air.
　つまり、図１２に示すように第二吹出口７７から吹出す上方への吹出空気流３５により、隣り合ったノズル６３の間に形成される誘引風路２２と最外部のノズル６３の外側の空気が誘引され、上方に向かう誘引空気流２６となる。これら上方への吹出空気流３５と誘引空気流２６が送風機能付空気清浄装置６１の第二吹出口７７からの吹出方向前方で合流するため、ノズル６３を起立させた方向への循環気流を効率よく生み出すことができる。すなわち、誘引風路２２は、ルーバー７８が閉じている際には第一吹出口６９からの高圧空気の吹出し空気に誘引される空気の誘引風路２２となり、ルーバー７８が開いている際には、第二吹出口７７からの高圧空気の吹出し空気に誘引される空気の誘引風路２２として機能する。 In other words, as shown in FIG. 12, the air outside the outermost nozzle 63 and the induction air passage 22 formed between the adjacent nozzles 63 by the upward air flow 35 blown out from the second air outlet 77. Is attracted, and the air flow 26 is directed upward. Since the upward blown air flow 35 and the induced air flow 26 merge in front of the blowout direction from the second blowout port 77 of the air cleaning device 61 with the blowing function, the circulating airflow in the direction in which the nozzle 63 is erected is efficient. Can be produced well. That is, when the louver 78 is closed, the induction air passage 22 becomes the air induction air passage 22 attracted by the high-pressure air blown air from the first air outlet 69, and when the louver 78 is open. It functions as the air induction air passage 22 that is attracted by the high-pressure air blown out from the second air outlet 77.
　また、複数の第二吹出口７７の位置がノズル６３の起立方向に対して同一面となるため、第二吹出口７７からの高圧空気の吹出しにより誘引風路２２の空気を効率よく誘引することができる。そして、第二吹出口７７からの高圧空気に誘引空気が加わることでノズル６３を起立させた方向の気流を増幅することができ、ノズル６３を鉛直上方へ起立させた場合には、室内の天井方向への循環気流を効率よく生み出すことが期待できる。 Moreover, since the position of the several 2nd blower outlet 77 becomes the same surface with respect to the standing direction of the nozzle 63, the air of the induced air path 22 is efficiently attracted | sucked by the blowing of the high pressure air from the 2nd blower outlet 77. Can do. Then, the induced air is added to the high-pressure air from the second outlet 77 to amplify the airflow in the direction in which the nozzle 63 is erected. When the nozzle 63 is erected vertically upward, the ceiling in the room It can be expected to efficiently generate a circulating airflow in the direction.
　また、ルーバー７８の角度を調節すれば、循環気流の方向を調整することも可能となり、室内の形状に応じて最適な循環気流を生み出すことが期待できる。 Also, by adjusting the angle of the louver 78, it is possible to adjust the direction of the circulating airflow, and it can be expected to produce an optimal circulating airflow according to the shape of the room.
　また、ルーバー７８を開いた状態において複数の第二吹出口７７の開口面積の合計の方が複数のノズル６３の第一吹出口６９の開口面積の合計より大きくしているため、高圧空気は、空気抵抗の少ない第二吹出口７７から多く吹出すことになり、効率よくノズル６３を起立させた方向の循環気流を生み出すことができる。 In addition, since the sum of the opening areas of the plurality of second outlets 77 is larger than the sum of the opening areas of the first outlets 69 of the plurality of nozzles 63 in a state where the louver 78 is opened, the high-pressure air is A large amount of air is blown out from the second air outlet 77 with low air resistance, and a circulating airflow in the direction in which the nozzle 63 is erected can be efficiently generated.
　なお、本実施の形態では、ノズル６３の起立方向に対する垂直方向の断面形状を長方形としたが、吹出し方向に縦長であればよく、楕円など別の形状でもよい。また、空気浄化フィルタ１５には、既知の集塵フィルタや活性炭などの脱臭フィルタを用いることができる。この空気浄化フィルタ１５を通過した空気は、ほこりや花粉、アレルギー物質などが取り除かれた浄化空気となり羽根車１６に供給される。 In the present embodiment, the cross-sectional shape in the direction perpendicular to the standing direction of the nozzle 63 is rectangular, but it may be vertically long in the blowing direction, and may be another shape such as an ellipse. The air purification filter 15 can be a known deodorizing filter such as a dust collection filter or activated carbon. The air that has passed through the air purification filter 15 is supplied to the impeller 16 as purified air from which dust, pollen, allergens, and the like have been removed.
　また、本実施の形態では、空気浄化フィルタ１５を備えた送風機能付空気清浄装置６１での形態を説明したが、送風装置としては、空気浄化フィルタ１５は、必須ではない。 Moreover, although the form in the air purifying apparatus 61 with the ventilation function provided with the air purification filter 15 was demonstrated in this Embodiment, the air purification filter 15 is not essential as an air blower.
　（第６の実施の形態）
　図１３、図１４に送風装置８１の斜視図を示す。なお、第１の実施の形態と同様の構成要素については同一の符号を付し、その詳細な説明は省略する。 (Sixth embodiment)
13 and 14 are perspective views of the blower 81. FIG. In addition, the same code | symbol is attached | subjected about the component similar to 1st Embodiment, and the detailed description is abbreviate | omitted.
　図１３に示すように、送風装置８１は、図８と同様な複数のノズル６３の上部をチャンバー空間８３で繋いでおり、複数の誘引風路２２はそれぞれ独立した構成となっている。図１４に示すように、チャンバー空間８３は、複数のノズル６３の上部に備えられた複数の流出口８２と連通しており、最上部に第二吹出口７７と、第二吹出口７７を開閉するルーバー７９と、ルーバー７９の回転軸８０を軸として回転駆動するルーバー駆動モータ８４を備えている。 As shown in FIG. 13, the air blower 81 connects the upper portions of a plurality of nozzles 63 similar to those in FIG. 8 with a chamber space 83, and the plurality of induction air passages 22 have independent configurations. As shown in FIG. 14, the chamber space 83 communicates with a plurality of outlets 82 provided above the plurality of nozzles 63, and opens and closes the second outlet 77 and the second outlet 77 at the top. A louver 79, and a louver drive motor 84 that rotates around the rotation shaft 80 of the louver 79 as an axis.
　室内に設置した空気調和装置等から吹付けられた空気が誘引風路２２に対して外乱となる恐れがある。 There is a possibility that the air blown from an air conditioner installed in the room may cause a disturbance to the induced air passage 22.
　しかし、本実施の形態の構成によれば、ルーバー７９を閉じた状態では、チャンバー空間８３によりノズル６３の上方から吹き付けられる気流を遮ることができるので、安定して面気流を発生させることができる。なお、面気流は、広範囲に略均一な風速の気流で、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成されるため直進性に優れ、風速の減衰が少なく遠方まで到達することができるものである。 However, according to the configuration of the present embodiment, when the louver 79 is closed, the airflow blown from above the nozzle 63 by the chamber space 83 can be blocked, so that the surface airflow can be generated stably. . In addition, the surface airflow is an airflow with a substantially uniform wind speed over a wide range, and since the airflow is linear in the blowing direction, the core area is formed in the center of the surface airflow, so it is excellent in straightness, with little attenuation of the wind speed Can reach up to.
　また、ルーバー７９を開けた状態では、複数の流出口８２を通過した高圧空気がチャンバー空間８３内で混合され、まとまった状態で第二吹出口７７から吹出されため、吹出し気流の中心部にコア領域が形成される。これにより直進性に優れ、風速の減衰が少なく遠方まで到達することができるため、ノズル６３を起立させた方向への循環気流を効率よく生み出すことができる。なお、ノズル６３を鉛直上方へ起立させた場合には、室内の天井方向への循環気流を効率よく生み出すことが期待できる。 Further, when the louver 79 is opened, the high-pressure air that has passed through the plurality of outlets 82 is mixed in the chamber space 83 and blown out from the second outlet 77 in a collective state. A region is formed. As a result, it is excellent in straight traveling performance and can reach far away with little attenuation of the wind speed, so that it is possible to efficiently generate a circulating airflow in the direction in which the nozzle 63 is erected. In addition, when the nozzle 63 is erected vertically upward, it can be expected to efficiently generate a circulating airflow in the indoor ceiling direction.
　また、羽根車１６を筐体１２で内包することで使用者の接触による不安感をなくしつつ、広範囲に略均一な風速の気流を提供することができる。 In addition, by enclosing the impeller 16 in the casing 12, it is possible to provide an air flow with a substantially uniform wind speed over a wide range, while eliminating anxiety due to the user's contact.
　さらに、ルーバー７９の角度を調節すれば、循環気流の方向を調整することも可能となり、室内の形状に応じて最適な循環気流を生み出すことが期待できる。 Furthermore, if the angle of the louver 79 is adjusted, it is possible to adjust the direction of the circulating airflow, and it can be expected to produce an optimal circulating airflow according to the shape of the room.
　なお、本実施の形態の送風装置８１は、吸込口１４に取り入れた空気を浄化する空気浄化フィルタ１５を装着することで送風機能付空気清浄装置とすることもできる。 In addition, the air blower 81 of this Embodiment can also be set as the air purifier with a ventilation function by mounting | wearing the air purification filter 15 which purifies the air taken in into the suction inlet 14. FIG.
　（第７の実施の形態）
　本発明の第７の実施の形態における送風装置９１のノズル９３は、図１５Ａ～図１５Ｃに示すように、吹出口９８の個数と位置を選択する変更装置としての開閉装置１０６を備えている。開閉装置１０６は、図１５Ａに示すように、吹出口９８を覆うことのできる略平板状の板状部材１０７と、板状部材１０７を回転駆動するステッピングモータ１０８と、気流を噴出させるノズル９３の位置を選択する操作部（図示せず）を備えている。ステッピングモータ１０８はノズル９３上部に配置している。ステッピングモータ１０８の回転によって板状部材１０７が回動し、吹出口９８を開閉することができる。 (Seventh embodiment)
As shown in FIGS. 15A to 15C, the nozzle 93 of the blowing device 91 according to the seventh embodiment of the present invention includes an opening / closing device 106 as a changing device for selecting the number and position of the air outlets 98. As shown in FIG. 15A, the opening / closing device 106 includes a substantially flat plate-like member 107 that can cover the air outlet 98, a stepping motor 108 that rotationally drives the plate-like member 107, and a nozzle 93 that ejects airflow. An operation unit (not shown) for selecting a position is provided. The stepping motor 108 is disposed above the nozzle 93. The plate member 107 is rotated by the rotation of the stepping motor 108, and the air outlet 98 can be opened and closed.
　図１５Ｂは、吹出口９８を開いた開状態を示し、図１５Ｃは吹出口９８を閉じた閉状態を示している。開閉装置１０６は、複数のノズル９３にそれぞれ備えられており、高圧空気を吹出す吹出口９８をそれぞれ独立して開閉させることができる。 FIG. 15B shows an open state in which the air outlet 98 is opened, and FIG. 15C shows a closed state in which the air outlet 98 is closed. The opening / closing device 106 is provided in each of the plurality of nozzles 93, and can individually open and close the outlets 98 that blow out the high-pressure air.
　上記構成によれば、使用者の人数や位置に合わせて、送風範囲を調整することができ、快適性を向上させることができる。 According to the above configuration, it is possible to adjust the air blowing range according to the number and position of users, and to improve comfort.
　例えば、図１６Ａおよび図１６Ｂに示すように、使用者２人（使用者Ｘ、使用者Ｙ）が離れている場合、図１６Ａに示すように全てのノズル９３を開いて使用しても、真ん中の２本のノズル９３からの吹出空気流２５と誘引空気流２６は無駄になる。気流を噴出すノズル９３の位置を操作部（図示せず）で選択することで、ステッピングモータ１０８が板状部材１０７を回動させて、選択されたノズル９３を開状態にして気流を噴出すこととなり、使用者Ｘ、使用者Ｙの位置に合わせて送風を行うことができる。すなわち、図１６Ｂに示すように、ノズル９３の６本のうち使用者に気流があたらない真ん中に位置する２本のノズル９３の吹出口９８を閉じて使用することができる。 For example, as shown in FIGS. 16A and 16B, when two users (user X and user Y) are separated, even if all nozzles 93 are opened and used as shown in FIG. The blown air flow 25 and the induced air flow 26 from the two nozzles 93 are wasted. By selecting the position of the nozzle 93 that ejects the airflow with an operation unit (not shown), the stepping motor 108 rotates the plate-like member 107 to open the selected nozzle 93 and eject the airflow. That is, it is possible to blow air according to the positions of the user X and the user Y. That is, as shown in FIG. 16B, the nozzles 98 of the two nozzles 93 located in the middle of the six nozzles 93 that are not exposed to the airflow can be closed and used.
　また、気流を噴出すノズル９３の個数が操作部（図示せず）で選択されることとなり、風量を増加させることもできる。すなわち、ステッピングモータ１０８が板状部材１０７を回動させて、真ん中の２本を閉じることで、使用者Ｘおよび使用者Ｙにあたらない部分には吹出空気流２５の供給が停止されることとなり、高圧空気は残りの４本のノズル９３に分配されることとなる。これにより開状態になっているノズル９３の吹出口９８からの吹出空気流２５は風速が増加し、誘引空気流２６の量が増え、離れている使用者２人の快適性が向上する。 Also, the number of nozzles 93 that eject the airflow is selected by the operation unit (not shown), and the airflow can be increased. That is, the stepping motor 108 rotates the plate-like member 107 and closes the middle two members, so that the supply of the blown air flow 25 is stopped to the portion not corresponding to the user X and the user Y. The high-pressure air is distributed to the remaining four nozzles 93. As a result, the blown air flow 25 from the air outlet 98 of the nozzle 93 in the open state increases in wind speed, the amount of the induced air flow 26 increases, and the comfort of two users who are away from each other is improved.
　また、ノズル９３が６本とも開いている場合と同じ程度の風量でよい場合には、モータ１７（図３参照）の出力を減らすことができ、消費電力を低減することが可能となる。この場合、モータ１７の回転数を制御する装置を備えることで、容易に風量を調節することができる。 Further, when the air volume is almost the same as when all six nozzles 93 are open, the output of the motor 17 (see FIG. 3) can be reduced, and the power consumption can be reduced. In this case, the air volume can be easily adjusted by providing a device for controlling the rotation speed of the motor 17.
　なお、本実施の形態では真ん中の２本のノズル９３の吹出口９８を閉じたが、使用者の状況に応じて、右半分のノズル９３の吹出口９８だけを閉じたり、１本おきにノズル９３の吹出口９８閉じたりする使い方も可能である。 In the present embodiment, the air outlets 98 of the middle two nozzles 93 are closed. However, depending on the situation of the user, only the air outlet 98 of the right half nozzle 93 is closed or every other nozzle. It is also possible to close 93 outlets 98.
　（第８の実施の形態）
　本発明の第８の実施の形態における送風装置について図とともに説明する。図１７Ａ～図１７Ｄは本発明の第８の実施の形態における送風装置１１１の要部を示す。送風装置１１１では、第７の実施の形態における送風装置９１のノズル９３に設けた開閉装置１０６に換えて、別の構成とした。ここでは、第１の実施の形態および第７の実施の形態と異なる点についてのみ説明をする。図１７Ａは、本実施の形態における送風装置の筐体を正面から見た断面図である。図１７Ｂは、本実施の形態における送風装置の吹出口の開状態を示す拡大図である。図１７Ｃは、本実施の形態における送風装置の吹出口の閉状態を示す拡大図である。そして、図１７Ｄは、本実施の形態における送風装置の一部の吹出口が閉状態であることを示す、チャンバー空間側からダクトの方向を見た下面図である。 (Eighth embodiment)
A blower apparatus according to an eighth embodiment of the present invention will be described with reference to the drawings. 17A to 17D show a main part of the blower 111 in the eighth embodiment of the present invention. The blower device 111 has a different configuration in place of the opening / closing device 106 provided in the nozzle 93 of the blower device 91 in the seventh embodiment. Here, only differences from the first embodiment and the seventh embodiment will be described. FIG. 17A is a cross-sectional view of the air blower housing according to the present embodiment as viewed from the front. FIG. 17B is an enlarged view showing an open state of the air outlet of the air blower in the present embodiment. FIG. 17C is an enlarged view showing a closed state of the air outlet of the blower in the present embodiment. And FIG. 17D is the bottom view which looked at the direction of the duct from the chamber space side which shows that some blower outlets of the air blower in this Embodiment are a closed state.
　筐体１２内の高圧空気発生部１８と複数のノズル１１６のダクト１１９の間には高圧空気をそれぞれのノズル１１６に分流するチャンバー空間２１が備えられている。図１７Ａ～図１７Ｃに示すように、本実施の形態は、チャンバー空間２１からそれぞれのノズル１１６のダクト１１９への分岐部１１２に、風路の開閉装置１１３を備えている。 Between the high-pressure air generating unit 18 in the housing 12 and the duct 119 of the plurality of nozzles 116, a chamber space 21 for diverting the high-pressure air to each nozzle 116 is provided. As shown in FIGS. 17A to 17C, in the present embodiment, an air path opening / closing device 113 is provided at a branch portion 112 from the chamber space 21 to the duct 119 of each nozzle 116.
　開閉装置１１３は、シート状で風路を遮断する遮断部材１１５と、遮断部材１１５を巻き取るステッピングモータ１１４から構成されている。 The opening / closing device 113 includes a sheet-shaped blocking member 115 that blocks the air passage, and a stepping motor 114 that winds the blocking member 115.
　図１７Ｂは分岐部１１２を開いた開状態を示し、図１７Ｃは分岐部１１２を閉じた閉状態を示している。図１７Ｃに示すようにステッピングモータ１１４が回転し、分岐部１１２を塞ぐようにシート状の遮断部材１１５を広げることで、分岐部１１２においてチャンバー空間２１からダクト１１９への通風路を遮断し、高圧空気がダクト１１９へ流れなくなるものである。また、図１７Ｂに示すように、ステッピングモータ１１４が回転し、シート状の遮断部材１１５を巻き取ることでダクト１１９とチャンバー空間２１が連通し、高圧空気をダクト１１９へ流すことができる。 FIG. 17B shows an open state in which the branch portion 112 is opened, and FIG. 17C shows a closed state in which the branch portion 112 is closed. As shown in FIG. 17C, the stepping motor 114 rotates and the sheet-like blocking member 115 is expanded so as to block the branching portion 112, thereby blocking the ventilation path from the chamber space 21 to the duct 119 at the branching portion 112. Air does not flow to the duct 119. Further, as shown in FIG. 17B, the stepping motor 114 rotates and the sheet-like blocking member 115 is wound up, whereby the duct 119 and the chamber space 21 communicate with each other, and high-pressure air can flow into the duct 119.
　開閉装置１１３は、複数のダクト１１９の分岐部１１２にそれぞれ備えられており、高圧空気を流す分岐部１１２をそれぞれ独立して開閉させることができる。 The opening / closing device 113 is provided in each of the branch portions 112 of the plurality of ducts 119, and can individually open and close the branch portions 112 through which high-pressure air flows.
　図１７Ｄは、６本のノズル１１６のダクト１１９とチャンバー空間２１をつなぐ６つの分岐部１１２のうち真ん中にある２つの分岐部１１２を閉じた状態をチャンバー空間２１側からダクト１１９の方向を見た下面図である。つまり、図１７Ｄでは、６つある分岐部１１２が左から順番に「開」、「開」、「閉」、「閉」、「開」、「開」の状態になっている。 FIG. 17D shows the state where the two branch portions 112 in the middle of the six branch portions 112 connecting the duct 119 of the six nozzles 116 and the chamber space 21 are closed, as viewed from the chamber space 21 side. It is a bottom view. That is, in FIG. 17D, the six branch sections 112 are in the “open”, “open”, “closed”, “closed”, “open”, and “open” states in order from the left.
　上記構成によれば、第７の実施の形態と同様に使用者の人数や位置に合わせて、送風範囲を調整することができ、快適性を向上させることができる。 According to the above configuration, the air blowing range can be adjusted in accordance with the number and positions of users as in the seventh embodiment, and comfort can be improved.
　また、開閉装置１１３が、筐体１２内に収まった構成となるので、外観を変えることなく送風範囲を変更することができ、デザイン性に優れた送風装置を提供することができる。 Further, since the opening / closing device 113 is housed in the housing 12, the blower range can be changed without changing the appearance, and a blower device excellent in design can be provided.
　また、羽根車１６は筐体１２内に内包されているため、使用者が外部から接触できない構造となっているため、接触による不安感をなくすことができる。 In addition, since the impeller 16 is included in the housing 12, the structure is such that the user cannot contact from the outside, so that anxiety due to contact can be eliminated.
　さらに、開閉装置１１３に使用者の手が接触することがなくなるので開閉装置１１３が故障する可能性を減らすことができる。 Furthermore, since the user's hand does not come into contact with the switchgear 113, the possibility that the switchgear 113 will break down can be reduced.
　なお、開閉装置１１３は、シート状の遮断部材１１５と、遮断部材１１５を巻き取るステッピングモータ１１４としたが、平板状の板を回転開閉させる機構や、スライドさせるなどで風路を遮断できる構成であれば、作用効果に差異は生じない。 Although the opening / closing device 113 is a sheet-like blocking member 115 and a stepping motor 114 that winds the blocking member 115, the opening / closing device 113 has a mechanism that rotates and opens a flat plate or a structure that can block an air path by sliding it. If so, there will be no difference in effect.
　（第９の実施の形態）
　本発明の第９の実施の形態における送風装置では、第７の実施の形態に用いた開閉装置１０６、または第８の実施の形態で用いた開閉装置１１３に換えて別の構成とした。ここでは、第７の実施の形態および第８の実施の形態と異なる点についてのみ説明をする。 (Ninth embodiment)
The air blower in the ninth embodiment of the present invention has a different configuration in place of the switchgear 106 used in the seventh embodiment or the switchgear 113 used in the eighth embodiment. Here, only differences from the seventh embodiment and the eighth embodiment will be described.
　図１８Ａ～図１８Ｃに本実施の形態における送風装置１２１の構成を示す。本実施の形態の送風装置１２１は、筐体１２から一部のノズル１２３を取り外し、ノズル１２３を取り外したあとで、カバー１２４によってふたができる構成となっている。 18A to 18C show the configuration of the blower device 121 in this embodiment. The blower device 121 of the present embodiment has a configuration in which a part of the nozzles 123 are removed from the housing 12 and the cover 124 can be closed after the nozzles 123 are removed.
　図１８Ａは、６本のノズル１２３のうち１本を筐体１２から外し、カバー１２４でふたをした状態を示している。図１８Ｂは、取り外したノズル１２３の斜視図であり、図１８Ｃはカバー１２４の斜視図である。 FIG. 18A shows a state in which one of the six nozzles 123 is removed from the housing 12 and covered with the cover 124. FIG. 18B is a perspective view of the removed nozzle 123, and FIG. 18C is a perspective view of the cover 124.
　上記構成によれば、ノズル１２３を筐体１２から取り外すことで、誘引風路２２が広がるので、風路抵抗が減ることになる。そのため、誘引される空気が流れやすくなり、気流の風速減衰が少なくなり、遠方まで気流を到達させることが可能となる。 According to the above configuration, by removing the nozzle 123 from the housing 12, the induced air passage 22 is widened, so that the air passage resistance is reduced. Therefore, the attracted air can easily flow, the wind speed attenuation of the airflow is reduced, and the airflow can reach far away.
　また、図１９Ａ～図１９Ｃは、天井１３０や室内壁１３１の窪みに納める形で送風装置１２１を設置した一例を示している。図１９Ａに示すように天井１３０に取り付けることで、室内の空気を循環させるなど、天井扇のように用いることができる。また、図１９Ｂに示すように室内壁１３１の窪みに送風装置１２１を納めることで、設置していても人の活動を妨げないようにすることもできる。 Further, FIGS. 19A to 19C show an example in which the blower 121 is installed so as to be housed in a recess in the ceiling 130 or the indoor wall 131. As shown in FIG. 19A, it can be used like a ceiling fan, such as circulating indoor air by attaching to the ceiling 130. In addition, as shown in FIG. 19B, by placing the blower device 121 in the recess of the indoor wall 131, it is possible not to disturb human activities even if it is installed.
　しかしながら、図１９Ｃに示すように、図１９Ａ、図１９Ｂの設置方法では、送風装置１２１の前面全体から高圧空気が吹出す状態となっているため、誘引される空気がノズル１２３の背面側に回り込むことができなくなり、誘引される空気の供給量が減少し、全体の風量が低下する。 However, as shown in FIG. 19C, in the installation method of FIGS. 19A and 19B, high pressure air is blown out from the entire front surface of the blower device 121, so the attracted air wraps around the back side of the nozzle 123. The amount of air that is attracted decreases, and the overall air flow decreases.
　そこで本実施の形態の構成を備え、図２０Ａ、図２０Ｂに示すように、複数あるノズル１２３を周りの環境に合わせて一部を筐体１２から取り外すことによって、誘引される空気の供給経路を確保して、吹出空気流の影響を受けにくい空間を作ることができる。つまり、空間を通って、誘引される空気が取り付けられているノズル１２３の背面側に回り込むことが可能となる。これにより、誘引される空気が十分に供給されることになり、誘引される空気の減少を防ぐことが可能となる（図２０Ａ、図２０Ｂでは、６本の中で左右の一番外側のノズル１２３を外し、カバー１２４でふたをしている）。 Therefore, the structure of the present embodiment is provided, and as shown in FIGS. 20A and 20B, a plurality of nozzles 123 are removed from the housing 12 in accordance with the surrounding environment, thereby providing an air supply path that is attracted. It is possible to secure a space that is not easily affected by the air flow. That is, it becomes possible to go through the space to the back side of the nozzle 123 to which the air to be attracted is attached. As a result, the attracted air is sufficiently supplied, and it is possible to prevent a decrease in the attracted air (in FIG. 20A and FIG. 20B, the right and left outermost nozzles among the six nozzles) 123 is removed and covered with a cover 124).
　なお、本実施の形態では、ノズル１２３を外すことで誘引される空気の供給を可能としているが、ノズル１２３を外さずに、６本あるノズル１２３の中のいずれかの吹出口１２９からの高圧空気の吹出しを止めることでも、同様の効果を得ることが可能となる。また、図２０Ａ、図２０Ｂでは、６本あるノズル１２３の中で左右の一番外側のノズル１２３を外しているが、一番外側以外のノズル１２３を外した場合でも、同様の効果を得ることができる。 In this embodiment, it is possible to supply air that is attracted by removing the nozzle 123, but the high pressure from any one of the six nozzles 123 without removing the nozzle 123 is high. It is possible to obtain the same effect by stopping the blowing of air. 20A and 20B, the left and right outermost nozzles 123 are removed from the six nozzles 123, but the same effect can be obtained even when the nozzles 123 other than the outermost are removed. Can do.
　また、本実施の形態では、カバー１２４は筐体１２から完全に取り外す構成にしているが、カバー１２４が筐体１２と接続された状態であってもよい。例えば、ノズル１２３を筐体１２に取り付けた時にカバー１２４が筐体１２内へ押し込まれチャンバー空間２１とダクト（図示せず）が連通し、ノズル１２３を取り外した時に、ばねなどの反発力を利用して、カバー１２４が自動でふたをするような構成であってもよい。 In this embodiment, the cover 124 is completely removed from the housing 12, but the cover 124 may be connected to the housing 12. For example, when the nozzle 123 is attached to the housing 12, the cover 124 is pushed into the housing 12, the chamber space 21 and the duct (not shown) communicate with each other, and when the nozzle 123 is removed, a repulsive force such as a spring is used. The cover 124 may be configured to automatically close the lid.
　以上説明したように、本発明の送風装置は、筐体に、空気を取り入れる吸込口と、高圧空気を発生するための羽根車と羽根車を駆動するためのモータで構成された高圧空気発生部と、筐体の一面から起立させた複数のノズルとを備える。また、ノズルは、側部に、ノズルを起立させた方向に対して垂直方向に高圧空気発生部で発生した高圧空気を吹出す第一吹出口を備えるとともに、内部に、高圧空気を吹出口に導くためのダクトを備える。また、ノズルは、起立させた方向に対する垂直方向の断面が吹出方向に縦長であり、複数の第一吹出口は同じ方向に向かって間隙を設けて備えられ、その間隙によって、吹出口から吹出す空気に誘引される空気の誘引風路が形成されている。 As described above, the air blower of the present invention has a high-pressure air generating unit that includes a suction port for taking air into an enclosure, an impeller for generating high-pressure air, and a motor for driving the impeller. And a plurality of nozzles erected from one surface of the housing. In addition, the nozzle includes a first blow-out port that blows out high-pressure air generated by the high-pressure air generation unit in a direction perpendicular to the direction in which the nozzle is erected on the side, and the high-pressure air is provided inside the blow-out port. A duct for guiding is provided. In addition, the nozzle has a longitudinal section in the blowing direction that is perpendicular to the upright direction, and the plurality of first outlets are provided with a gap in the same direction, and the nozzle blows out from the outlet through the gap. An air attraction air passage attracted by air is formed.
　このように、羽根車を内包することで接触による不安感をなくしつつ、第一吹出口からの高圧空気の吹出しにより誘引される空気が小さくならないよう間隙を設けて複数のノズルが備えられている。そのため、複数の第一吹出口から吹出された高圧空気と、吹出口からの高圧空気の吹出しにより誘引される空気からなる面気流を広範囲に略均一な風速の気流とすることができる。また、第一吹出口を同じ方向に向かって設けることで、吹出す気流は面気流となる。この面気流は広範囲に略均一な風速の、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成されるため直進性に優れ、風速の減衰が少なく遠方まで到達することができる。 In this way, a plurality of nozzles are provided with a gap so that air attracted by blowing high-pressure air from the first air outlet is not reduced while anxiety due to contact is eliminated by including the impeller. . For this reason, a surface airflow composed of high-pressure air blown from the plurality of first air outlets and air attracted by the high-pressure air blown from the air outlets can be made into an airflow having a substantially uniform wind speed over a wide range. Moreover, the air flow which blows off becomes a surface air current by providing the 1st blower outlet toward the same direction. This surface airflow is a uniform air velocity over a wide area and is linear in the blowing direction, so the core area is formed in the center of the surface airflow, so it has excellent straightness and the wind speed is less attenuated and reaches far away. Can do.
　ここで、複数のノズルとは３本以上のことを示し、略均一な風速とは最大風速の半分までの風速を示し、高圧空気とは大気圧以上の空気を示すものとする。なお、間隙の長さとしては、ノズルの起立させた方向に対する垂直方向の断面における吹出方向と垂直方向の長さ以上であり、ノズルの起立方向長さの半分以下が風速の均一性を得られるため好ましい。 Here, a plurality of nozzles indicates three or more nozzles, a substantially uniform wind speed indicates a wind speed up to half of the maximum wind speed, and a high-pressure air indicates air above atmospheric pressure. Note that the length of the gap is not less than the length in the direction perpendicular to the blowing direction in the cross section perpendicular to the direction in which the nozzle is erected, and less than half of the length in the erection direction of the nozzle can provide uniform wind speed. Therefore, it is preferable.
　また、本発明の送風装置は、複数のノズルを、筐体の中央から外側に設けられたノズルに向かうにつれて中央のノズルに対して空気の吹出し方向が離れていくように広角に備えてもよい。 Moreover, the air blower of the present invention may be provided with a plurality of nozzles at a wide angle so that the air blowing direction is away from the central nozzle as it goes from the center of the housing to the nozzle provided outside. .
　面気流は広範囲に略均一な風速の、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成されるため、遠方に向かうにつれ中心部の風速が大きくなる風速分布となる。しかし、ノズルを筐体中心から外側に設けられたノズルに向かうにつれて広角に備えることで中心部に気流が集まるのを抑制でき、遠方まで略均一な風速の気流を送ることができる。 The surface airflow is a uniform air velocity over a wide area and is linear in the blowing direction, so a core region is formed in the center of the surface airflow, so the wind speed distribution increases in the center as it goes farther. . However, by providing the nozzles with a wide angle from the center of the casing toward the nozzles provided on the outside, it is possible to suppress the airflow from being collected at the center, and it is possible to send an airflow with a substantially uniform wind speed to a distance.
　また、本発明の送風装置は、複数のノズルの起立方向の長さを同一としてもよい。 Further, in the blower of the present invention, the lengths of the plurality of nozzles in the standing direction may be the same.
　この構成により、複数のノズルが並んでいる方向の風速の均一性に加え、ノズルの起立方向に対してもすべてのノズルで略均一にできるため、広範囲に略均一な風速の面気流を提供することができる。また、面気流は広範囲に略均一な風速の、吹出方向に直線的な気流のため、面気流の中心部にコア領域が形成されるため直進性に優れ、遠方まで風速の減衰が少なく到達することができる。 With this configuration, in addition to the uniformity of the wind speed in the direction in which a plurality of nozzles are arranged, all the nozzles can be made substantially uniform in the upright direction of the nozzles, thereby providing a surface airflow with a substantially uniform wind speed over a wide range. be able to. In addition, the surface airflow is almost uniform over the wide area, and the airflow is straight in the blowing direction, so the core area is formed in the center of the surface airflow, so it is excellent in straightness and reaches far away with little wind speed attenuation. be able to.
　また、本発明の送風装置は、ダクトの風路断面が吹出口からの吹出方向に縦長であり、ノズルを起立させた先端に向かうにつれて小さくなるような構成としてもよい。 Also, the air blower of the present invention may be configured such that the air passage cross section of the duct is vertically long in the blowing direction from the blowout port and becomes smaller toward the tip where the nozzle is erected.
　ダクトを通る高圧空気の風量は一部を吹出口から吹出され、ノズルを起立させた先端に向かうにつれて小さくなる。そこで、ダクトの風路断面を、ノズルを起立させた先端に向かうにつれて小さくすることにより、ノズルを起立させた先端に向かうにつれてダクトの内部静圧が低下するのを抑制することができ、吹出口から吹出す高圧空気の風速をノズルの起立方向に均一化でき、広範囲に略均一な風速の面気流を提供することができる。 The air volume of the high-pressure air passing through the duct is blown out partly from the outlet and decreases as it goes to the tip where the nozzle is erected. Therefore, by reducing the duct air passage cross section toward the tip where the nozzle is erected, the internal static pressure of the duct can be suppressed from decreasing toward the tip where the nozzle is erected. The air velocity of the high-pressure air blown out from the nozzle can be made uniform in the standing direction of the nozzle, and a surface air flow having a substantially uniform air velocity can be provided over a wide range.
　また、本発明の送風機能付空気清浄装置は、送風装置の吸込口に、空気浄化フィルタを備えてもよい。 Moreover, the air purifier with a blowing function of the present invention may include an air purification filter at the suction port of the blowing device.
　この構成により、吸込口から取り込まれた空気は空気浄化フィルタにより浄化され吹出口から吹出されるため、使用者に浄化された空気を提供することができる。 With this configuration, the air taken in from the suction port is purified by the air purification filter and blown out from the outlet, so that the purified air can be provided to the user.
　また、本発明の送風装置のノズルは、ノズルの最上部でノズルを起立させた方向に開口させた高圧空気を吹き出す第二吹出口を備えるとともに、第二吹出口を開閉可能にしたルーバーを備えてもよい。 In addition, the nozzle of the blower of the present invention includes a second air outlet that blows out high-pressure air that is opened in the direction in which the nozzle is raised at the uppermost portion of the nozzle, and includes a louver that can open and close the second air outlet. May be.
　この構成により、第二吹出口に備えたルーバーを閉じた状態では直接気流に当たることによる涼感が得られ、また、ルーバーを開くことでノズルを起立させた方向への気流の吹出しが加えられるため、室内空気の循環を実現することができる。 With this configuration, in the state where the louver provided for the second outlet is closed, a cool feeling by directly hitting the airflow is obtained, and by blowing out the airflow in the direction in which the nozzle is erected by opening the louver, Circulation of room air can be realized.
　また、ルーバーを閉じた状態では、間隙を設けて複数のノズルを備えているため、複数の第一吹出口から吹出された高圧空気と、第一吹出口からの高圧空気の吹出しにより誘引される空気からなる気流を広範囲に略均一な風速の気流とすることができる。 Further, when the louver is closed, a plurality of nozzles are provided with gaps, so that it is attracted by the high-pressure air blown from the plurality of first air outlets and the high-pressure air blown from the first air outlets. The air stream made of air can be made into an air stream having a substantially uniform wind speed over a wide range.
　また、ルーバーを開いた状態では、間隙を設けて複数のノズルが備えられているため、複数の第二吹出口から吹出された高圧空気に加え、第二吹出口からの高圧空気に誘引空気が加わることで天井方向の気流を増幅することができ、ノズルを起立させた方向への循環気流を効率よく生み出すことができる。 In addition, when the louver is opened, a plurality of nozzles are provided with gaps, so that in addition to the high-pressure air blown out from the plurality of second air outlets, the induced air is added to the high-pressure air from the second air outlets. By adding, the airflow in the ceiling direction can be amplified, and a circulating airflow in the direction in which the nozzle is raised can be efficiently generated.
　すなわち、誘引風路はルーバーが閉じている際には第一吹出口からの高圧空気の吹出し空気に誘引される空気の誘引風路となり、ルーバーが開いている際には、第二吹出口からの高圧空気の吹出し空気に誘引される空気の誘引風路として機能するものである。また、ルーバーの角度により循環気流の方向を調整することが可能なため、室内の形状に応じて最適な循環気流を生み出すことができる。 That is, when the louver is closed, the induction air passage becomes an air induction air passage attracted by the high-pressure air blowing air from the first air outlet, and when the louver is open, It functions as an air pulling path for air that is attracted by the high-pressure air blowing air. In addition, since the direction of the circulating airflow can be adjusted by the angle of the louver, an optimal circulating airflow can be generated according to the shape of the room.
　また、本発明の送風装置は、ノズルが、高圧空気を吹き出す流出口を備え、内部に第一吹出口と流出口へ高圧空気を導くためのダクトを備えた筒体であって、複数のノズルの上部に複数の流出口からの高圧空気を混合するチャンバー空間と、混合した高圧空気を吹出す第二吹出口を備える。そして、第二吹出口をチャンバー空間の最上部でノズルを起立させた方向に開口して備え、第二吹出口を開閉可能にしたルーバーを備えてもよい。 Further, the blower of the present invention is a cylinder having a nozzle having an outlet that blows out high-pressure air, and a duct that guides the high-pressure air to the first outlet and the outlet. A chamber space for mixing high-pressure air from a plurality of outlets, and a second outlet for blowing out the mixed high-pressure air. And you may provide the louver which opened and provided the 2nd blower outlet in the direction which made the nozzle stand up at the uppermost part of chamber space, and was able to open and close the 2nd blower outlet.
　この構成により、第二吹出口に備えたルーバーを閉じた状態では直接気流に当たることにより涼感を得られ、また、ルーバーを開くことでノズルを起立させた方向への気流の吹出しが加えられるため、室内の空気循環を実現することができる。 With this configuration, in the state where the louver provided at the second outlet is closed, a cool feeling can be obtained by directly hitting the air flow, and by blowing the air flow in the direction in which the nozzle is raised by opening the louver, Indoor air circulation can be realized.
　また、ルーバーを開いた状態では、複数のダクトを通過した高圧空気がチャンバー空間で混合され、まとまった状態で第二吹出口から吹出されため、吹出し気流の中心部にコア領域が形成される。このため直進性に優れ、遠方まで風速の減衰が少なく到達することができるため、循環気流としてノズルを起立させた方向への気流を効率よく生み出すことができる。 Also, in a state where the louver is opened, high pressure air that has passed through a plurality of ducts is mixed in the chamber space and blown out from the second outlet in a unified state, so that a core region is formed at the center of the blown airflow. For this reason, it is excellent in straightness and can reach far away with little attenuation of the wind speed, so that it is possible to efficiently generate an air flow in the direction in which the nozzle is raised as a circulating air flow.
　また、ルーバーの角度を調節すれば、循環気流の方向を調整することも可能となり、室内の形状に応じて最適な循環気流を生み出すことが期待できる。 Also, by adjusting the angle of the louver, it is possible to adjust the direction of the circulating airflow, and it can be expected to produce an optimal circulating airflow according to the shape of the room.
　また、本発明は、複数の第二吹出口の開口面積の合計を複数のノズルの第一吹出口の開口面積の合計より大きくしてもよい。 In the present invention, the total opening area of the plurality of second outlets may be larger than the total opening area of the first outlets of the plurality of nozzles.
　このように、ルーバーを開いた状態において、複数の第二吹出口の開口面積の合計の方が複数のノズルの第一吹出口の開口面積の合計より大きいため、第二吹出口全体の空気抵抗は第一吹出口全体の空気抵抗よりも小さく、高圧空気は空気抵抗の少ない第二吹出口から多く吹出す。そのため、ノズルの起立方向へ優先的に気流が吹出され、効率よく循環気流を生み出すことができる。 Thus, in the state where the louver is opened, since the sum of the opening areas of the plurality of second air outlets is larger than the sum of the opening areas of the first air outlets of the plurality of nozzles, the air resistance of the entire second air outlet Is smaller than the air resistance of the entire first air outlet, and high pressure air is blown out from the second air outlet having a low air resistance. Therefore, the airflow is preferentially blown in the nozzle standing direction, and a circulating airflow can be efficiently generated.
　また、本発明の送風装置は、少なくとも３本のノズルを備え、高圧空気を吹出す第一吹出口の個数と位置とを選択する変更装置を備えてもよい。 Moreover, the air blower of the present invention may include a change device that includes at least three nozzles and selects the number and position of the first air outlets that blow out the high-pressure air.
　このように、変更装置を備えたことで、高圧空気を吹出す第一吹出口の個数と位置を選択することができるので、第一吹出口から吹出される高圧空気により誘引される空気も使用者の位置や人数に合わせて、送風範囲を調節することができ、快適性を向上させることができるという効果を奏する。ここで、高圧空気とは大気圧以上の空気を示すものとする。 Thus, since the change device is provided, it is possible to select the number and position of the first air outlets that blow out the high-pressure air, so air that is attracted by the high-pressure air that is blown out from the first air outlet is also used. The air blowing range can be adjusted according to the position and number of persons, and the comfort can be improved. Here, high-pressure air refers to air at atmospheric pressure or higher.
　また、本発明の送風装置は、変更装置が、第一吹出口に備えられた、第一吹出口をそれぞれ開閉する開閉装置としてもよい。 Moreover, the air blower of this invention is good also as an opening / closing device with which a change apparatus was equipped with the 1st blower outlet, and each opened and closed the 1st blower outlet.
　この構成により、第一吹出口を開閉することが可能となるので、使用者の位置や人数に合わせて、送風範囲を調整することができ、快適性を向上させることができるという効果を奏する。 This configuration makes it possible to open and close the first air outlet, so that the air blowing range can be adjusted according to the position and number of users and the comfort can be improved.
　また、本発明の送風装置は、変更装置が、高圧空気発生部からダクトへ繋がる分岐部に備えられた、分岐部を開閉する開閉装置としてもよい。 Further, in the blower device of the present invention, the changing device may be an opening / closing device that opens and closes the branching portion provided in the branching portion connected to the duct from the high-pressure air generating portion.
　この構成により、開閉装置で分岐部を開閉することが可能となるので、高圧空気を吹出す個数と位置を選択することができ、使用者の位置や人数に合わせて、送風範囲を調節することができ、快適性を向上させることができるという効果を奏する。また、筐体内に開閉装置を収めることが可能となるので、外観を変えることなく送風範囲を変更することができ、デザイン性に優れた送風装置を得ることができる。さらに、開閉装置に接触することがなくなるので開閉装置の故障のリスクを減らすことができる。 With this configuration, the branching unit can be opened and closed with an opening and closing device, so the number and position of high pressure air can be selected, and the blowing range can be adjusted according to the position and number of users. It is possible to improve the comfort. In addition, since the opening / closing device can be housed in the housing, the blowing range can be changed without changing the appearance, and a blowing device with excellent design can be obtained. Furthermore, since the contact with the switchgear is eliminated, the risk of failure of the switchgear can be reduced.
　また、本発明の送風装置は、変更装置を、筐体とノズルとの間に介在して設けられたカバーとしてもよい。 In the air blower of the present invention, the change device may be a cover provided between the housing and the nozzle.
　この構成により、ノズルの本数を変更して、第一吹出口の個数と位置を選択することができるので、高圧空気を吹出す個数と位置を選択することができ、使用者の位置や人数に合わせて、送風範囲を調節することができ、快適性を向上させることができる。また、ノズルを取り外すことで誘引される空気の風路が広がり、風路の圧損が減るので、誘引される空気が流れやすくなり、気流の風速の減衰を少なくすることができ遠方まで気流を到達させることができるという効果を奏することもできる。 With this configuration, the number and position of the first outlet can be selected by changing the number of nozzles, so the number and position of the high-pressure air can be selected, and the position and number of users can be selected. In addition, the air blowing range can be adjusted, and comfort can be improved. In addition, the air path of the air that is attracted by removing the nozzle widens and the pressure loss of the air path is reduced, so that the air that is attracted flows easily, and the attenuation of the wind speed of the air current can be reduced and the air stream reaches far away The effect that it can be made can also be produced.
　本発明にかかる送風装置および送風機能付空気清浄装置は、羽根車を内包することで使用者の接触による不安感をなくしつつ、広範囲に略均一な風速の気流を提供できるため、居室内の床、天井や室内壁に設置され、直接気流による体感温度の減少や室内の空気の循環に使用される各種送風機器として有用である。 The air blowing device and the air purifying device with the air blowing function according to the present invention can provide an air flow with a substantially uniform wind speed over a wide range while eliminating the anxiety caused by the user's contact by including the impeller. It is installed on the ceiling and indoor walls, and is useful as various blower devices used to reduce the temperature of sensation due to direct airflow and to circulate indoor air.
