Description

送風装置および空気清浄機能付送風装置Blower and air blower with air purifying function
　本発明は、送風装置および空気清浄機能付送風装置に関するものである。 The present invention relates to a blower and a blower with an air cleaning function.
　従来、送風装置として、羽根車とモータを台座となる基部に内包して、基部上部に備えられた円環形状の送風部から床面と水平方向に空気を吹出すようにして空気の循環及び空気の流れを生じさせる家庭用送風装置が知られている（例えば、特許文献１参照）。この種の送風装置は、例えば扇風機や天井扇として居室内に設置され、直接気流による体感温度の減少や室内空気の循環に使用される。また、この種の送風装置は、送風装置内に取り込む空気を浄化し、浄化した空気を直接気流による体感温度の減少や室内の空気の循環にしようすることで、空気清浄機能付送風装置としても機能する。 Conventionally, as an air blower, an impeller and a motor are included in a base serving as a pedestal, and air is circulated and blown from an annular air blower provided at the upper part of the base in the horizontal direction with the floor surface. A household blower that generates an air flow is known (see, for example, Patent Document 1). This type of blower is installed in a living room as, for example, a fan or a ceiling fan, and is used to reduce the sensible temperature due to direct airflow or to circulate room air. In addition, this type of air blower purifies the air taken into the air blower, and uses the purified air as a direct air current to reduce the temperature of sensible temperature and to circulate indoor air. Function.
　以下、その送風装置について図７および図８を参照しながら説明する。 Hereinafter, the blower will be described with reference to FIG. 7 and FIG.
　図７は、従来の送風装置の一例を示す正面図である。図８は、従来の送風装置の一例を示す断面図である。なお、図８は、図７の８－８線断面図である。送風装置である送風機組立体１００は、中央開口部１０２を画定する環状ノズル１０１を有している。送風機組立体１００の基部１１６内部には、環状ノズル１０１を通る空気流を生じさせる送風装置が配置されている。図８に示すように、インペラ（羽根車）１３０が、モータハウジング１２６と共に配置されたモータ１２２から外方に延びる回転シャフトに連結されている。また、ディフューザ１３２が、インペラ１３０の下流側に位置決めされている。モータ１２２は、図示しない電気接続部及び電源に接続されている。ユーザは、複数個の選択ボタン１２０により、送風機組立体１００を操作することができる。 FIG. 7 is a front view showing an example of a conventional blower. FIG. 8 is a cross-sectional view showing an example of a conventional blower. 8 is a cross-sectional view taken along line 8-8 in FIG. A blower assembly 100 as a blower has an annular nozzle 101 that defines a central opening 102. Inside the base 116 of the blower assembly 100, a blower that generates an air flow through the annular nozzle 101 is disposed. As shown in FIG. 8, an impeller (impeller) 130 is connected to a rotating shaft that extends outward from a motor 122 that is disposed with the motor housing 126. Further, the diffuser 132 is positioned on the downstream side of the impeller 130. The motor 122 is connected to an electrical connection unit and a power source (not shown). The user can operate the blower assembly 100 with the plurality of selection buttons 120.
　上記構成で、送風機組立体１００は、以下のように動作する。 With the above configuration, the blower assembly 100 operates as follows.
　ユーザが複数個の選択ボタン１２０の中から好みのボタンを選択してモータ１２２が起動されると、空気が空気入口１２４を介して送風機組立体１００内に吸い込まれる。空気は、外側ケーシング１１８を通り、インペラ１３０の入口１３４まで流れる。ディフューザ１３２の出口１３６及びインペラ１３０の排気部を出た空気流は、内部通路１１０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 selects a desired button from the plurality of selection buttons 120 and the motor 122 is activated, air is sucked into the blower assembly 100 through the air inlet 124. Air flows through the outer casing 118 to the inlet 134 of the impeller 130. The air flow that exits the outlet 136 of the diffuser 132 and the exhaust portion of the impeller 130 is divided into two air flows that travel in opposite directions through the internal passage 110.
　空気流は、口１１２に入る際に絞られ、口１１２の出口１４４で更に絞られる。この絞りにより、環状ノズル１０１内に圧力が生じる。 The airflow is squeezed as it enters the mouth 112 and further squeezed at the outlet 144 of the mouth 112. Due to this restriction, pressure is generated in the annular nozzle 101.
　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１４４を通って出る。一次空気流は、ガイド部分１４８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１４４周りの領域及び環状ノズル１０１の外縁部周りからの空気が一次空気流に吸引されることで生じる。この二次空気流は、中央開口部１０２を通り、ここで、一次空気流と混ざり合って送風機組立体１００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 144 as a primary air flow. The primary air flow is directed or focused toward the user due to the arrangement of the guide portion 148. The secondary air flow is generated when air from the outside environment, particularly the area around the outlet 144 and around the outer edge of the annular nozzle 101, is sucked into the primary air flow. This secondary air flow passes through the central opening 102 where there is a total air flow that mixes with the primary air flow and is discharged forward from the blower assembly 100.
特開２０１０－０７７９６９号公報JP 2010-077969 A
　このような従来の送風装置では、二次空気流は、出口から出た一次空気流が外部環境、特に出口周りの領域及び環状ノズルの外縁部周りからの空気を吸引することで生じるものである。そのため、中央開口部の環状ノズル近傍では空気の吸引が大きく、中央開口部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、広範囲に気流を送るために環状ノズルの直径を大きくすると、中央開口部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, the secondary air flow is generated when the primary air flow coming out of the outlet sucks air from the outside environment, particularly the area around the outlet and the outer periphery of the annular nozzle. . Therefore, the air suction is large in the vicinity of the annular nozzle in the central opening, and the air suction is reduced as the center of the central opening is approached. For this reason, when the diameter of the annular nozzle is increased in order to send the airflow over a wide range, the airflow near the center of the central opening is reduced, and there is a problem that it is impossible to provide an airflow with a substantially uniform wind speed over a wide range.
　そこで本発明は、上記従来の課題を解決するものであり、広範囲に略均一な風速の気流を提供することを実現できる送風装置、および空気清浄機能付送風装置を提供することを目的とする。 Therefore, the present invention solves the above-described conventional problems, and an object thereof is to provide a blower capable of providing an air flow having a substantially uniform wind speed over a wide range, and a blower with an air cleaning function.
　そして、この目的を達成するために、本発明は、空気を取入れる吸込口を備えた筐体と、筐体の内部で高圧空気を発生する羽根車と羽根車を駆動するモータとを備えた高圧空気発生部と、筐体の側面で互いに間隔をとって筐体の中心軸を中心として放射状に延設した複数の柱状体とを有し、柱状体は側部に吹出口を備え、柱状体は内部に吹出口に連通するダクトを備え、柱状体は高圧空気発生部で発生させた高圧空気を中心軸方向に対して鋭角にかつ外向きに吹出すノズルを備え、間隔がノズルを介して吹出口から吹出される高圧空気によって誘引される誘引空気の誘引風路を形成し、中心軸側に吹出口から吹出す高圧空気の到達しない負圧領域が設けられた送風装置としたものであり、これにより所期の目的を達成するものである。 And in order to achieve this objective, this invention was equipped with the housing | casing provided with the inlet port which takes in air, the impeller which generate | occur | produces high pressure air inside a housing | casing, and the motor which drives an impeller. The high-pressure air generating section and a plurality of columnar bodies extending radially around the central axis of the casing at intervals from each other on the side surface of the casing. The body has a duct that communicates with the air outlet, and the columnar body has a nozzle that blows out high-pressure air generated by the high-pressure air generator at an acute angle and outward with respect to the central axis direction. This is a blower device that forms an induced air passage for the induced air that is attracted by the high-pressure air that is blown from the air outlet, and that is provided with a negative pressure area that does not reach the high-pressure air that is blown from the air outlet on the central axis side. Yes, and this achieves the intended purpose.
　本発明に係る送風装置および空気清浄機能付送風装置は、広範囲に略均一な風速の気流を提供することを実現できる。 The blower and the blower with an air purifying function according to the present invention can provide an air flow having a substantially uniform wind speed over a wide range.

　本発明の請求項１に係る送風装置は、空気を取入れる吸込口を備えた筐体と、筐体の内部で高圧空気を発生する羽根車と羽根車を駆動するモータとを備えた高圧空気発生部と、筐体の側面で互いに間隔をとって筐体の中心軸を中心として放射状に延設した複数の柱状体とを有し、柱状体は側部に吹出口を備え、柱状体は内部に吹出口に連通するダクトを備え、柱状体は高圧空気発生部で発生させた高圧空気を中心軸方向に対して鋭角にかつ外向きに吹出すノズルを備え、間隔がノズルを介して吹出口から吹出される高圧空気によって誘引される誘引空気の誘引風路を形成し、中心軸側に吹出口から吹出される高圧空気の到達しない負圧領域が設けられたことを特徴とするものである。 A blower according to claim 1 of the present invention is a high-pressure air including a housing having a suction port for taking in air, an impeller that generates high-pressure air inside the housing, and a motor that drives the impeller. The generator has a plurality of columnar bodies radially extending around the central axis of the casing, spaced apart from each other on the side surface of the casing, the columnar body is provided with a blowout port on the side, and the columnar body is A duct communicating with the air outlet is provided inside, and the columnar body is provided with a nozzle that blows out high-pressure air generated by the high-pressure air generator at an acute angle and outward with respect to the central axis direction, and the interval is blown through the nozzle. It is characterized by forming an induced air passage for attracted air that is attracted by high-pressure air blown from the outlet, and a negative pressure region that does not reach the high-pressure air blown from the blow-out outlet is provided on the central axis side. is there.
　これにより、吹出口から吹出される高圧空気により誘引される空気の風路が小さくならないよう複数の柱状体が互いに間隔をとって筐体の中心軸を中心に放射状に延設されているため、効率よく柱状体の外縁部周りの空気を誘引することができる。吹出口から吹出される高圧空気を中心軸方向に対して鋭角にかつ外向きに吹出すことで、中心軸側に吹出口から吹出される高圧空気の到達しない負圧領域設けることができる。そのため、負圧領域の作用により高圧空気と高圧空気に誘引される誘引空気の一部を中心軸側に引き寄せることができる。これにより、複数の吹出口から吹出された高圧空気と、吹出口から吹出される高圧空気により誘引される誘引空気からなる面気流を、放射状に延設された柱状体に対応する円領域内で広範囲に略均一な風速の気流とすることができる。 Thereby, since the plurality of columnar bodies are radially extended around the central axis of the housing so as not to reduce the air path of the air attracted by the high-pressure air blown out from the outlet, Air around the outer edge of the columnar body can be efficiently attracted. By blowing the high-pressure air blown from the blower outlet at an acute angle and outward with respect to the central axis direction, a negative pressure region where the high-pressure air blown from the blower outlet does not reach can be provided on the central axis side. Therefore, a part of the attraction air attracted to the high pressure air and the high pressure air by the action of the negative pressure region can be drawn toward the central axis side. Thereby, the surface airflow consisting of the high-pressure air blown out from the plurality of air outlets and the attraction air attracted by the high-pressure air blown out from the air outlets is within a circular region corresponding to the radially extending columnar body. An air flow having a substantially uniform wind speed can be obtained over a wide range.
　ここで、略均一な風速とは、放射状に延設された柱状体に対応する円領域内における最小風速が、少なくとも最大風速の半分までである場合をいう。また、高圧空気とは大気圧以上の圧力を有する空気を示すものとする。 Here, “substantially uniform wind speed” refers to a case where the minimum wind speed in the circular region corresponding to the radially extending columnar body is at least half of the maximum wind speed. Moreover, high pressure air shall show the air which has a pressure more than atmospheric pressure.
　また、請求項２に係る送風装置は、複数の柱状体を等間隔に備えたことを特徴とするものである。 The air blower according to claim 2 is characterized in that a plurality of columnar bodies are provided at equal intervals.
　これにより、各誘引風路の大きさが等しくなり、柱状体の吹出口から吹出される高圧空気により誘引される誘引空気の量を同一にすることができる。そのため、複数の吹出口から吹出された高圧空気と、吹出口から吹出される高圧空気により誘引される誘引空気からなる面気流を放射状に延設された柱状体に対応する円領域内で広範囲に略均一な風速の気流とすることができる。 Thus, the size of each induction air passage becomes equal, and the amount of induction air that is induced by the high-pressure air that is blown out from the outlet of the columnar body can be made the same. Therefore, a wide area within a circular region corresponding to a columnar body radially extending a surface airflow composed of high-pressure air blown out from a plurality of outlets and induced air induced by high-pressure air blown out from the outlets. It can be set as the air current of a substantially uniform wind speed.
　また、請求項３に係る送風装置は、柱状体が有する吹出口と中心軸をはさんで柱状体と対向する位置に設けられた柱状体が有する吹出口とは、中心軸を中心とした円の円周上に配置されていることを特徴とするものである。 Further, in the blower according to claim 3, the air outlet of the columnar body and the air outlet of the columnar body provided at a position facing the columnar body across the central axis are a circle centered on the central axis. It is arrange | positioned on the circumference of this.
　これにより、吹出口から吹出される高圧空気の吹出し方向を中心軸に対して同心円上で対称にすることができる。高圧空気によって誘引される誘引空気も高圧空気の吹出し方向に応じて流れるため、複数の吹出口から吹出された高圧空気と、吹出口から吹出された高圧空気により誘引される誘引空気からなる面気流を放射状に延設された柱状体に対応する円領域内で広範囲に略均一な風速の気流とすることができる。 This makes it possible to make the blowing direction of the high-pressure air blown out from the blowout port concentrically with respect to the central axis. Since the induced air attracted by the high-pressure air also flows according to the direction of the high-pressure air blowing, the surface airflow is composed of the high-pressure air blown from the plurality of blow-out ports and the induced air drawn by the high-pressure air blown from the blow-out ports Can be made to be an air flow having a substantially uniform wind speed over a wide range within a circular region corresponding to the columnar body extending radially.
　また、請求項４に係る送風装置は、複数の柱状体の長さが等しいことを特徴とするものである。 Further, the blower according to claim 4 is characterized in that the lengths of the plurality of columnar bodies are equal.
　これにより、吹出口から吹出される高圧空気の吹出し方向を中心軸に対して対称にすることができる。誘引空気も高圧空気の吹出し方向に応じて流れるため、複数の吹出口から吹出された高圧空気と、吹出口から吹出される高圧空気により誘引される誘引空気からなる面気流を放射状に延設された柱状体に対応する円領域内で広範囲に略均一な風速の気流とすることができる。 This makes it possible to make the blowing direction of the high-pressure air blown out from the blowout port symmetrical with respect to the central axis. Since the induced air also flows according to the direction in which the high-pressure air is blown out, the surface airflow consisting of the high-pressure air blown from the plurality of outlets and the induced air drawn by the high-pressure air blown from the outlets is radially extended. In the circular region corresponding to the columnar body, it is possible to generate a substantially uniform air velocity over a wide range.
　また、請求項５に係る送風装置は、柱状体の放射方向の長さが、隣り合う柱状体間の長さの最大長さより大きいことを特徴とするものである。 Further, the blower according to claim 5 is characterized in that the radial length of the columnar body is larger than the maximum length between adjacent columnar bodies.
　これにより、柱状体の放射方向の最外部の吹出口でも、隣り合う吹出口から吹出される高圧空気により空気を誘引することができる。このため、複数の吹出口から吹出された高圧空気と、吹出口から吹出された高圧空気により誘引される誘引空気からなる面気流を放射状に延設された柱状体に対応する円領域の外周部にも広範囲に略均一な風速の気流とすることができる。 This allows air to be attracted by the high-pressure air blown from the adjacent blower outlets even at the outermost blower outlet in the radial direction of the columnar body. For this reason, the outer peripheral part of the circular area | region corresponding to the columnar body extended radially by the surface airflow which consists of the high pressure air blown from the several blower outlet and the attraction air attracted by the high pressure air blown from the blower outlet In addition, it is possible to obtain a substantially uniform air velocity over a wide range.
　また、請求項６に係る送風装置は、ダクトが形成する風路を横切る断面が吹出方向に縦長であることを特徴とするものである。 Further, the blower according to claim 6 is characterized in that a cross section crossing the air passage formed by the duct is vertically long in the blowing direction.
　これにより、高圧空気発生部で発生させた高圧空気のダクト内での放射方向の流れを、効率よく吹出口からの吹出し方向に整流することができる。 This makes it possible to efficiently rectify the radial flow in the duct of high-pressure air generated by the high-pressure air generator in the direction of blowing from the outlet.
　また、請求項７に係る送風装置は、ノズルから吹出口を介して吹出される空気の吹出風量が、中心軸側に比べて中心軸から離れた位置の方が大きいことを特徴とするものである。 The blower according to claim 7 is characterized in that the amount of air blown out from the nozzle through the outlet is larger at a position away from the central axis than at the central axis. is there.
　吹出口から吹出される吹出風量が全て同一の場合、柱状体の間隔が大きくなると、誘引される誘引空気量は、柱状体の延設方向の中心部よりも外側では相対的に小さくなりやすい。しかしながら、この構成によれば、柱状体の延設方向の中心部よりも外側で吹出口からの高圧空気の吹出風量が大きくすることで、柱状体の延設方向の外側の方で誘引される誘引空気量を大きくすることができる。このため、放射状に延設された柱状体に対応する円領域の外周部にも広範囲に略均一な風速の気流とすることができる。 When the amount of blown air blown from the outlet is the same, when the interval between the columnar bodies increases, the amount of attracted air that is attracted tends to be relatively small outside the central portion in the extending direction of the columnar bodies. However, according to this configuration, the amount of high-pressure air blown from the outlet is increased outside the central portion in the extending direction of the columnar body, so that it is attracted toward the outside in the extending direction of the columnar body. The amount of attracted air can be increased. For this reason, it is possible to obtain a substantially uniform air velocity over a wide range at the outer peripheral portion of the circular region corresponding to the columnar body extending radially.
　また、請求項８に係る送風装置は、吹出口を中心軸の一方向側へ向けて配置し、吸込口は吹出口とは逆の側に配置したことを特徴とするものである。 Further, the air blower according to claim 8 is characterized in that the air outlet is arranged toward one direction side of the central axis, and the air inlet is arranged on the side opposite to the air outlet.
　これにより、吹出口から吹出す高圧空気や、高圧空気に誘引される誘引空気が吸込口に吸い込まれるのを抑制することができるため、効率よく面気流を生み出すことができる。 This makes it possible to suppress the suction of high-pressure air that is blown out from the blow-out port or air that is attracted by the high-pressure air into the suction port, so that a surface airflow can be efficiently generated.
　また、請求項９に係る送風装置は、筐体が吹出口側の第一面と吹出口とは反対側の第二面を有し、中心軸方向において、吹出口を備えた側部から側部とは反対側の側部までの距離は、吹出口を備えた側部から第二面までの距離よりも小さいことを特徴とするものである。 In the air blower according to claim 9, the casing has a first surface on the air outlet side and a second surface on the opposite side of the air outlet, and in the central axis direction from the side portion provided with the air outlet. The distance to the side part opposite to the part is smaller than the distance from the side part provided with the air outlet to the second surface.
　これにより、第二面を天井や壁に接して送風装置を配置しても、吹出口を備えた柱状体の側部とは反対側の側部と第二面との間に間隙が生じるため、十分な誘引空気の風路を確保することができ、送風性能を維持することができる。 As a result, even if the blower is arranged with the second surface in contact with the ceiling or wall, a gap is generated between the second surface and the side portion opposite to the side portion of the columnar body provided with the air outlet. It is possible to secure a sufficient air passage for attracting air and maintain the blowing performance.
　また、請求項１０に係る空気清浄機能付送風装置は、送風装置の吸込口に、空気浄化フィルタを備えたことを特徴とする空気清浄機能付送風装置とするものである。 Further, the air purifying function-equipped blower according to claim 10 is an air purifying function-equipped blower characterized in that an air purifying filter is provided at the suction port of the air blowing apparatus.
　これにより、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。 Thereby, since the air taken in from the suction port is purified by the air purification filter and blown out from the air outlet, the purified air can be provided to the user.
　以下、本発明の実施の形態について図面を参照しながら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　（実施の形態１）
　図１は、実施の形態１の空気清浄機能付送風装置の斜視図である。図２は、実施の形態１の空気清浄機能付送風装置の正面図である。図３は、図２の３－３線断面図である。図４は、図２の４－４線断面図である。 (Embodiment 1)
1 is a perspective view of a blower with an air cleaning function according to Embodiment 1. FIG. FIG. 2 is a front view of the blower with an air cleaning function according to the first embodiment. 3 is a cross-sectional view taken along line 3-3 of FIG. 4 is a cross-sectional view taken along line 4-4 of FIG.
　図１に示すように、本実施の形態の送風装置である、空気清浄機能付送風装置１１は、筐体１２の第二面３５側を天井面または壁面に取付けて使用するものである。 As shown in FIG. 1, a blower 11 with an air cleaning function, which is a blower of the present embodiment, is used by attaching the second surface 35 side of the housing 12 to a ceiling surface or a wall surface.
　図２、図３に示すように空気清浄機能付送風装置１１は、筐体１２と、高圧空気発生部１８と、複数の柱状体１３とを有している。 As shown in FIGS. 2 and 3, the air cleaning function-equipped blower 11 includes a housing 12, a high-pressure air generator 18, and a plurality of columnar bodies 13.
　図３に示すように、筐体１２は、第一面３４と、第二面３５と、側面４３とからなる円筒である。筐体１２は、側面４３の上部、つまり側面４３の第二面３５側に配置され、筐体１２内に空気を取り入れる吸込口１４を備えている。また、取り入れた空気を浄化する円筒形状の空気浄化フィルタ１５が吸込口１４に装着されている。 As shown in FIG. 3, the housing 12 is a cylinder composed of a first surface 34, a second surface 35, and a side surface 43. The housing 12 is disposed on the upper side of the side surface 43, that is, on the second surface 35 side of the side surface 43, and includes a suction port 14 for taking air into the housing 12. A cylindrical air purification filter 15 that purifies the taken-in air is attached to the suction port 14.
　高圧空気発生部１８は、筐体１２の内部に設置されており、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とを備えている。 The high-pressure air generator 18 is installed inside the housing 12 and includes an impeller 16 for generating high-pressure air and a motor 17 for driving the impeller 16.
　柱状体１３は、複数あって、筐体１２の側面４３の下部から互いに等しい間隔をとって水平方向に筐体１２の中心軸２３を中心として放射状に延設されている。本実施の形態では、大きさが等しい１６本の柱状体１３が延設されている。 There are a plurality of columnar bodies 13 that extend radially from the lower portion of the side surface 43 of the housing 12 at equal intervals around the central axis 23 of the housing 12 in the horizontal direction. In the present embodiment, 16 columnar bodies 13 having the same size are extended.
　柱状体１３は、側部に吹出口１９を備えている。本実施の形態では、柱状体１３は角筒であるがこれに限定されない。なお、本実施の形態において、側部とは、柱状体１３における筐体１２の吸込口１４とは反対側（図３では下側の面）の面のことである。 The columnar body 13 includes an air outlet 19 on the side. In the present embodiment, the columnar body 13 is a square tube, but is not limited thereto. In the present embodiment, the side portion is a surface of the columnar body 13 opposite to the suction port 14 of the housing 12 (the lower surface in FIG. 3).
　また、柱状体１３は、内部に高圧空気を吹出口１９に導くためのダクト２０を備えている。つまり、ダクト２０は、吹出口１９に連通している。また、柱状体１３は、ダクト２０を、少なくとも柱状体１３と同数備えている。図４に示すように、ダクト２０が形成する風路を横切る断面、つまり、ダクト２０の放射方向に対して垂直な断面は、高圧空気の吹出方向に対して縦長になっている。これは、ダクト２０内における高圧空気の放射方向の流れを、効率よく吹出口１９からの吹出し方向に整流するためである。 Moreover, the columnar body 13 includes a duct 20 for guiding high-pressure air to the air outlet 19 inside. That is, the duct 20 communicates with the air outlet 19. Further, the columnar body 13 includes at least the same number of ducts 20 as the columnar bodies 13. As shown in FIG. 4, a cross section that crosses the air path formed by the duct 20, that is, a cross section that is perpendicular to the radial direction of the duct 20 is vertically long with respect to the high-pressure air blowing direction. This is because the flow of high-pressure air in the duct 20 in the radial direction is efficiently rectified in the blowing direction from the outlet 19.
　さらに、柱状体１３は、内部にノズル２１を備えている。ノズル２１は、高圧空気発生部１８で発生された高圧空気が中心軸２３方向に対して鋭角にかつ外向きに吹出口１９から吹出されるよう形成されている。つまり、高圧空気発生部１８で発生された高圧空気は、ダクト２０、ノズル２１を介して吹出口１９から吹出される。なお、柱状体１３は、少なくとも１つのノズル２１を有していればよい。 Furthermore, the columnar body 13 includes a nozzle 21 inside. The nozzle 21 is formed so that the high-pressure air generated by the high-pressure air generator 18 is blown from the outlet 19 at an acute angle and outward with respect to the direction of the central axis 23. That is, the high-pressure air generated by the high-pressure air generator 18 is blown out from the outlet 19 via the duct 20 and the nozzle 21. The columnar body 13 only needs to have at least one nozzle 21.
　柱状体１３は、ノズル側面３６（側部）と、ノズル側面３６に対向するダクト側面３７と、ノズル側面３６とダクト側面３７を所定の間隔に隔てさせる側壁とを有する。 The columnar body 13 has a nozzle side surface 36 (side portion), a duct side surface 37 facing the nozzle side surface 36, and a side wall that separates the nozzle side surface 36 and the duct side surface 37 at a predetermined interval.
　ノズル側面３６には、吹出口１９が設けられている。また、ノズル側面３６は、中心軸２３の方向において第一面３４と同じ側に配置されている。ダクト側面３７は、ノズル側面３６に対向して、つまり、中心軸２３の方向において第一面３４と反対側に設けられている。側壁の長さ、つまり、ノズル側面３６からダクト側面３７までの長さ（吹出口１９を備えた側部から反対側の側部までの最大の距離）は、ノズル側面３６から第二面３５までの長さより小さい。すなわち、ダクト側面３７は第二面３５に対して中心軸２３の方向で間隙を設けて備えられているものである。言い換えると、ダクト側面３７は、第二面３５よりも第一面３４側に設けられている。 The blower outlet 19 is provided on the nozzle side surface 36. Further, the nozzle side surface 36 is disposed on the same side as the first surface 34 in the direction of the central axis 23. The duct side surface 37 is provided opposite to the nozzle side surface 36, that is, on the side opposite to the first surface 34 in the direction of the central axis 23. The length of the side wall, that is, the length from the nozzle side surface 36 to the duct side surface 37 (the maximum distance from the side portion having the air outlet 19 to the opposite side portion) is from the nozzle side surface 36 to the second surface 35. Less than the length of That is, the duct side surface 37 is provided with a gap in the direction of the central axis 23 with respect to the second surface 35. In other words, the duct side surface 37 is provided closer to the first surface 34 than the second surface 35.
　図３に示すように、ノズル２１は、高圧空気発生部１８で発生された高圧空気を吹出口１９を介して中心軸２３の方向に対して鋭角にかつ外向きに吹出すように形成されている。また、隣り合う柱状体１３の間の間隔が、ノズル２１から吹出口１９を介して吹出される高圧空気によって誘引される誘引空気の風路である誘引風路２２（図４参照）を形成している。つまり、本実施の形態では柱状体１３を１６本設けているので、柱状体１３に挟まれた間隔にそれぞれ誘引風路２２が柱状体１３と同数の１６本形成される。ここで、ダクト２０と吹出口１９の間には、ノズル２１から吹出口１９を介して吹出される高圧空気の方向を制御する風向制御板２９が設けられている。風向制御板２９は、中心軸２３に近い中心部側の方が、中心軸２３から離れた外周部側よりも密に備えられている。風向制御板２９の詳細については後述する。 As shown in FIG. 3, the nozzle 21 is formed so that the high-pressure air generated by the high-pressure air generator 18 is blown out at an acute angle and outward with respect to the direction of the central axis 23 through the outlet 19. Yes. Moreover, the space | interval between adjacent columnar bodies 13 forms the induced air path 22 (refer FIG. 4) which is an air path of the induced air attracted by the high pressure air which blows off from the nozzle 21 through the blower outlet 19. ing. That is, since 16 columnar bodies 13 are provided in the present embodiment, the same number of 16 induction air passages 22 as the columnar bodies 13 are formed at intervals between the columnar bodies 13. Here, a wind direction control plate 29 is provided between the duct 20 and the air outlet 19 to control the direction of the high-pressure air blown from the nozzle 21 through the air outlet 19. The air direction control plate 29 is provided closer to the center side near the center axis 23 than to the outer peripheral side away from the center axis 23. Details of the wind direction control plate 29 will be described later.
　図２、図３に示すように、柱状体１３が備える吹出口１９と、中心軸２３をはさんで柱状体１３と対向する位置に設けられた柱状体１３が備える吹出口１９とは、中心軸２３を中心とした任意の半径の円の円周２４上に配置されている。図２に示すように、一例として柱状体１３Ｃが備える吹出口２５Ｃと、中心軸２３をはさんで柱状体１３Ｃと対向する位置に設けられた柱状体１３Ｄが備える吹出口２５Ｄとは、中心軸２３を中心とした円周２４上に配置されている。 As shown in FIGS. 2 and 3, the air outlet 19 provided in the columnar body 13 and the air outlet 19 provided in the columnar body 13 provided at a position facing the columnar body 13 across the central axis 23 are the center. It is arranged on the circumference 24 of a circle with an arbitrary radius centered on the axis 23. As shown in FIG. 2, as an example, the outlet 25C provided in the columnar body 13C and the outlet 25D provided in the columnar body 13D provided at a position facing the columnar body 13C across the central axis 23 are the central axis. It is arranged on a circumference 24 centering on 23.
　図２に示すように、複数の柱状体１３の放射方向長さ２７は等しい。また、放射方向長さ２７は、隣り合う柱状体１３間の間隔のうち、最大である最大間隔長さ２８より大きい。 As shown in FIG. 2, the radial lengths 27 of the plurality of columnar bodies 13 are equal. The radial length 27 is larger than the maximum maximum interval length 28 among the intervals between adjacent columnar bodies 13.
　なお、本実施の形態では、図２、図３において、一例として柱状体１３の本数が１６本、柱状体１３の幅が３５ｍｍ、柱状体１３の放射方向長さ２７が５００ｍｍ、最大間隔長さ２８が２３０ｍｍ、ノズル側面３６とダクト側面３７の幅が１８０ｍｍの場合を示している。また本実施の形態では、柱状体１３の垂直方向の断面形状は、長方形形状としたが、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。 In this embodiment, in FIGS. 2 and 3, as an example, the number of the columnar bodies 13 is 16, the width of the columnar bodies 13 is 35 mm, the radial length 27 of the columnar bodies 13 is 500 mm, and the maximum interval length. 28 shows a case where 230 mm and the width of the nozzle side surface 36 and the duct side surface 37 is 180 mm. Further, in the present embodiment, the vertical cross-sectional shape of the columnar body 13 is a rectangular shape, but may be a vertically long shape in the blowing direction, and may be another shape such as an ellipse.
　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。 Further, as the air purification filter 15, 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.
　次に、上記のように構成された図３に示す空気清浄機能付送風装置１１の動作について説明する。 Next, the operation of the air cleaning function-equipped blower 11 shown in FIG. 3 configured as described above will be described.
　このような構成によれば、空気清浄機能付送風装置１１が稼動すると、モータ１７が駆動し、羽根車１６が回転する。そして、内部流れ３２に示すように、室内空気は、吸込口１４から空気清浄機能付送風装置１１内部に取り込まれる。内部に取り込まれた空気は、空気浄化フィルタ１５で埃やにおいなどの汚れが取り除かれた浄化空気となる。浄化空気は、羽根車１６を通過し、高圧空気として柱状体１３に設けられたダクト２０に至る。高圧空気は複数のダクト２０、ノズル２１を通過し、ダクト２０と吹出口１９の間に設けられた風向制御板２９で風向を調整され、吹出口１９から吹出し、図１に示す吹出空気流３０となる。また、吹出空気流３０により、図１のように誘引風路２２を介して空気が誘引され、誘引空気流３１が生じる。 According to such a configuration, when the blower 11 with the air cleaning function operates, the motor 17 is driven and the impeller 16 rotates. And as shown to the internal flow 32, indoor air is taken in into the air blower 11 with an air purifying function from the suction inlet 14. FIG. The air taken into the inside becomes purified air from which dirt such as dust and smell is removed by the air purification filter 15. The purified air passes through the impeller 16 and reaches the duct 20 provided in the columnar body 13 as high-pressure air. The high-pressure air passes through a plurality of ducts 20 and nozzles 21, the air direction is adjusted by a wind direction control plate 29 provided between the ducts 20 and the air outlet 19, and is blown out from the air outlet 19. It becomes. Further, the blown air flow 30 attracts air through the induced air passage 22 as shown in FIG.
　つまり、吹出口１９から吹出された高圧空気である吹出空気流３０と、吹出口１９から吹出された高圧空気によって誘引される誘引空気である誘引空気流３１とが、面気流として空気清浄機能付送風装置１１から前面に吹出される。 That is, the air flow 30 that is the high-pressure air blown from the air outlet 19 and the air flow 31 that is the air that is attracted by the high-pressure air blown from the air outlet 19 are provided with an air cleaning function as a surface air flow. It blows out from the blower 11 to the front.
　吹出空気流３０は、中心軸２３方向に対して鋭角にかつ外向きに吹出すものであるので、放射状の中心部（中心軸２３）側には、吹出口１９から吹出す高圧空気の到達しない領域が存在する。これにより、放射状に延設された柱状体１３に形成されたノズル２１（図４参照）を介して吹出口１９から吹出される高圧空気により、放射状の中心部側には高圧空気の到達しない領域である負圧領域３３が存在することになる。なお、負圧領域３３とは、高圧空気が到達する領域よりも気圧が低い領域のことをいう。負圧領域３３の作用により高圧空気と高圧空気に誘引される誘引空気の一部を放射状の中心部側、つまり中心軸２３側である負圧領域３３に引き寄せることができる。このため、吹出空気流３０と誘引空気流３１からなる面気流を放射状に延設された柱状体１３に対応する円領域内で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、ここでいう略均一とは、吹出空気流３０と誘引空気流３１からなる面気流の風速の分布に基づいたものであり、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いう。本実施の形態では、観測した風速のうち、最小風速が少なくとも最大風速の半分である場合を略均一な風速としている。 Since the blown air flow 30 is blown outward at an acute angle with respect to the direction of the central axis 23, the high-pressure air blown from the blower outlet 19 does not reach the radial center portion (the central axis 23) side. An area exists. Thereby, the area where the high-pressure air does not reach the radial central portion side by the high-pressure air blown from the blow-out opening 19 via the nozzles 21 (see FIG. 4) formed in the columnar bodies 13 extending radially. That is, the negative pressure region 33 is present. The negative pressure region 33 refers to a region where the atmospheric pressure is lower than a region where high-pressure air reaches. The negative pressure region 33 can draw high pressure air and a part of the attraction air attracted to the high pressure air toward the radial central portion side, that is, the negative pressure region 33 on the central shaft 23 side. For this reason, it is possible to provide an air current having a substantially uniform wind speed over a wide area in a circular region corresponding to the columnar body 13 radially extending from the surface airflow composed of the blown air flow 30 and the induced air flow 31. The term “substantially uniform” as used herein is based on the wind speed distribution of the surface airflow composed of the blown air flow 30 and the induced air flow 31, and is observed on a plane viewed from the front at a predetermined distance from the blowout port 19. The distribution of the wind speed is said to be within a predetermined range. In the present embodiment, among the observed wind speeds, a case where the minimum wind speed is at least half of the maximum wind speed is regarded as a substantially uniform wind speed.
　また、羽根車１６は筐体１２内に内包されており、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 and has a structure in which the user cannot contact from the outside, the anxiety caused by the contact can be eliminated.
　ここで、複数の柱状体１３は、中心軸２３を中心として等しい長さで等間隔に備えられている。そして、柱状体１３が備える吹出口１９と、中心軸２３をはさんで柱状体１３と対向する位置にもうけられた柱状体１３が備える吹出口１９とは、中心軸２３を中心とした円の円周２４上に配置されている。そのため、吹出口１９からの高圧空気の吹出し方向を中心軸２３に対して対称にすることができる。また、高圧空気により誘引される誘引空気も高圧空気の吹出し方向に応じて流れる。つまり、高圧空気である吹出空気流３０と吹出空気流３０に誘引される誘引空気流３１は中心軸２３に対して対称に流れる。このため吹出空気流３０と誘引空気流３１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。 Here, the plurality of columnar bodies 13 are provided at equal intervals with the same length around the central axis 23. And the blower outlet 19 with which the columnar body 13 is equipped, and the blower outlet 19 with which the columnar body 13 provided in the position facing the columnar body 13 on both sides of the central axis 23 are the circle centering on the central axis 23. It is arranged on the circumference 24. Therefore, the blowing direction of the high-pressure air from the blower outlet 19 can be made symmetric with respect to the central axis 23. Moreover, the attraction air attracted by the high pressure air also flows in accordance with the direction in which the high pressure air is blown. That is, the blown air flow 30 that is high-pressure air and the induced air flow 31 attracted by the blown air flow 30 flow symmetrically with respect to the central axis 23. For this reason, the surface airflow which consists of the blowing air flow 30 and the induced air flow 31 can be made into the airflow of a substantially uniform wind speed over a wide range.
　また、風向制御板２９は、ダクト２０と吹出口１９の間に設けられており、中心軸２３側ほど密に配置されている。そのため、中心軸２３に近い吹出口１９から吹出される高圧空気ほど、吹出る際に受ける通風抵抗が大きい。また、中心軸２３から離れた吹出口１９から吹出される高圧空気が、吹出る際に受ける通風抵抗は小さい。つまり、中心軸２３から離れた吹出口１９から吹出される高圧空気のほうが吹出風量を大きくすることができる。一般的に、柱状体１３間の間隔が大きくなる柱状体１３の外周側では、誘引空気流３１が中心軸２３側よりも相対的に小さくなりやすい。しかしながら、本実施の形態のように、中心軸２３から離れた吹出口１９から吹出される高圧空気の吹出風量を、中心軸２３側の吹出口１９から吹出される高圧空気の吹出風量よりも大きくすることで、広範囲に略均一な気流を提供することができる。つまり、放射状に延設された柱状体１３に対応する円領域内における誘引空気流３１の風速分布のばらつきを抑えることができる。 Further, the wind direction control plate 29 is provided between the duct 20 and the air outlet 19 and is arranged closer to the central axis 23 side. For this reason, the higher the pressure air blown from the air outlet 19 near the central shaft 23, the greater the airflow resistance received when it is blown out. Moreover, the ventilation resistance which the high pressure air blown from the blower outlet 19 away from the central shaft 23 receives when blowing is small. That is, the amount of blown air can be increased with the high-pressure air blown from the blower outlet 19 away from the central shaft 23. In general, on the outer peripheral side of the columnar bodies 13 where the interval between the columnar bodies 13 becomes large, the induced air flow 31 tends to be relatively smaller than the central axis 23 side. However, as in the present embodiment, the amount of high-pressure air blown from the blower outlet 19 away from the central shaft 23 is larger than the amount of high-pressure air blown from the blower outlet 19 on the central shaft 23 side. By doing so, a substantially uniform air flow can be provided over a wide range. That is, it is possible to suppress variation in the wind speed distribution of the induced air flow 31 in the circular region corresponding to the columnar bodies 13 extending radially.
　また、柱状体１３は、中心軸２３方向において、筐体１２の吸込口１４が設けられた方向とは反対側の方向の側部（ノズル側面３６）に吹出口１９を備えている。そのため、吹出空気流３０や誘引空気流３１が吸込口１４に吸い込まれるのを抑制することができるため、効率よく面気流を生み出すことができる。 Further, the columnar body 13 includes a blower outlet 19 at a side portion (nozzle side surface 36) in a direction opposite to the direction in which the suction port 14 of the housing 12 is provided in the direction of the central axis 23. Therefore, since it can suppress that the blowing air flow 30 and the attraction air flow 31 are inhaled by the suction inlet 14, a surface airflow can be produced efficiently.
　また、図２に示す柱状体１３の放射方向長さ２７は隣り合う柱状体１３間の長さの最大間隔長さ２８より大きい。そのため、柱状体１３の放射方向の最外部の吹出口１９でも、隣り合う吹出口１９から吹出される高圧空気により空気を誘引することができる。よって、吹出空気流３０と誘引空気流３１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。 Further, the radial length 27 of the columnar bodies 13 shown in FIG. 2 is larger than the maximum interval length 28 between the adjacent columnar bodies 13. Therefore, even at the outermost outlet 19 in the radial direction of the columnar body 13, air can be attracted by the high-pressure air blown from the adjacent outlet 19. Therefore, the surface airflow composed of the blown air flow 30 and the induced air flow 31 can be made an airflow having a substantially uniform wind speed over a wide range.
　また、図３に示す中心軸２３方向において、ノズル側面３６からダクト側面３７までの距離は、ノズル側面３６から第二面３５までの距離よりも小さい。つまり、ダクト側面３７と第二面３５の間には間隙が設けられている。よって、第二面３５を天井や壁に接して送風装置を配置しても天井や壁と第二面３５との間には間隙が生じるため、十分な誘引空気の風路を確保することができ、送風性能を維持することができる。 Further, in the direction of the central axis 23 shown in FIG. 3, the distance from the nozzle side surface 36 to the duct side surface 37 is smaller than the distance from the nozzle side surface 36 to the second surface 35. That is, a gap is provided between the duct side surface 37 and the second surface 35. Therefore, even if the air blower is arranged with the second surface 35 in contact with the ceiling or wall, a gap is generated between the ceiling or wall and the second surface 35, so that a sufficient air path for the induced air can be secured. And the air blowing performance can be maintained.
　なお、本実施の形態では、空気浄化フィルタ１５を備えた空気清浄機能付送風装置１１の形態を説明した。しかしながら、空気浄化フィルタ１５は、送風装置としては必須ではない。空気浄化フィルタ１５を用いない場合は、空気清浄機能付送風装置１１は、単に送風装置として機能する。 In addition, in this Embodiment, the form of the air cleaner 11 with the air purifying function provided with the air purifying filter 15 was demonstrated. However, the air purification filter 15 is not essential as a blower. When the air purification filter 15 is not used, the blower 11 with an air cleaning function simply functions as a blower.
　（実施の形態２）
　図５は、送風装置４１を天井面４２に設置した斜視図である。図６は、送風装置４１の正面図である。なお、実施の形態１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。 (Embodiment 2)
FIG. 5 is a perspective view in which the blower 41 is installed on the ceiling surface 42. FIG. 6 is a front view of the blower 41. In addition, the same code | symbol is attached | subjected about the component similar to Embodiment 1, and the detailed description is abbreviate | omitted.
　送風装置４１は図１と同様な構成であるが、図５、図６に示すように複数の柱状体１３（本実施形態では２４本）の長さが異なる。具体的には、長い柱状体１３が１２本、短い柱状体１３が１２本交互に配置された構成となっている。図６に示すように、長い柱状体１３の放射方向長さ２７は隣り合う柱状体１３間の長さの最大間隔長さ２８より大きい。本実施の形態に係る送風装置４１は、放射方向長さ２７の長さが異なる柱状体１３を備えている。この場合、長い柱状体１３と隣の長い柱状体１３の間の領域、つまり短い柱状体１３がない領域の空気の誘引を効率よく行う必要がある。なお、ここでの隣り合うノズル２１間とは、長い柱状体１３と隣の長い柱状体１３の間のことを示し、最大間隔長さ２８もこの間の長さを示すものである。 The air blower 41 has the same configuration as that in FIG. 1, but the lengths of the plurality of columnar bodies 13 (24 in this embodiment) are different as shown in FIGS. Specifically, 12 long columnar bodies 13 and 12 short columnar bodies 13 are alternately arranged. As shown in FIG. 6, the radial length 27 of the long columnar body 13 is larger than the maximum interval length 28 between the adjacent columnar bodies 13. The blower device 41 according to the present embodiment includes the columnar body 13 having a radial length 27 that is different. In this case, it is necessary to efficiently attract air in a region between the long columnar body 13 and the adjacent long columnar body 13, that is, a region without the short columnar body 13. Here, the term “between adjacent nozzles 21” indicates the distance between the long columnar body 13 and the adjacent long columnar body 13, and the maximum interval length 28 also indicates the length between them.
　このような構成によれば、長い柱状体１３の放射方向長さ２７は、隣り合う長い柱状体１３間の長さの最大間隔長さ２８より大きい。そのため、長い柱状体１３の放射方向の最外部の吹出口１９でも、隣り合う吹出口１９から吹出される高圧空気により空気を誘引することができるため、吹出空気流３０と誘引空気流３１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。 According to such a configuration, the radial length 27 of the long columnar body 13 is larger than the maximum interval length 28 between the adjacent long columnar bodies 13. Therefore, even the outermost air outlet 19 in the radial direction of the long columnar body 13 can attract air by the high-pressure air blown from the adjacent air outlets 19, and therefore includes the blown air flow 30 and the induced air flow 31. The surface airflow can be made to be an airflow having a substantially uniform wind speed over a wide range.
　また、天井面４２とダクト側面３７（図３参照）が間隙を設けて備えられているため、十分な誘引空気の風路を確保することができ、送風性能を維持することができる。 Further, since the ceiling surface 42 and the duct side surface 37 (see FIG. 3) are provided with a gap, a sufficient air passage for the induced air can be secured and the blowing performance can be maintained.
　なお、本実施の形態の送風装置４１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を装着することで空気清浄機能付送風装置とすることもできる。 In addition, the air blower 41 of this Embodiment can also be set as the air blower with an air purifying function by mounting | wearing the air purification filter 15 which purifies the air taken in into the suction inlet 14. FIG.
　本発明にかかる送風装置および空気清浄機能付送風装置は、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。そのため、居室内の床、天井や壁に設置され、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等として有用である。 The air blower and air blower with an air purifying function according to the present invention can provide an air flow with a substantially uniform wind speed over a wide range while eliminating anxiety due to the user's contact by including the impeller. Therefore, it is installed as a floor, ceiling, or wall in a living room, and is useful as various blower devices used to reduce the temperature of sensation due to direct airflow and to circulate indoor air.
