Description
この発明は、空気を強制的に吸引するファンに関するものである。 The present invention relates to a fan that forcibly sucks air.
従来のファンは、一方向に吸引するだけの構造で、空気の流れを作る構造だった。 The conventional fan has a structure that only sucks in one direction and creates an air flow.
従来、空気を換気する場合、ファンは一方向だけ風の流れを作って吸引していたので、狭い範囲の空気を入れ換える場合には、効率が悪かった。本発明は、簡易な構造で効率良く空気を吸引するためになされたものである。 In the past, when ventilating air, the fan created a flow of wind in only one direction and sucked it, so it was inefficient when exchanging air in a narrow range. The present invention has been made to efficiently suck air with a simple structure.
プロペラファンの構造を同軸二重構造とし、一つの回転でありながら、内側で空気を吸引する様に羽を配置することで竜巻状の渦によって吸い出すと同時に、外側は逆方向の風を吹き出す様に羽を配置する構造とし、内側と同じく竜巻状の流れになる様に空気を吹き出す構造とする。更に、単位時間当たりに動く空気の量を「単位風量」と定義すると、（外側の吹き出す単位風量）≦（内側の吸い出す単位風量）とすることにより実現するものである。 The structure of the propeller fan is a coaxial double structure, and while it is one rotation, by arranging the wings so as to suck air inside, it sucks out by a tornado-shaped vortex, and at the same time, it blows out the wind in the opposite direction on the outside. The structure is such that the wings are placed on the inside, and the air is blown out so that the flow becomes a tornado like the inside. Further, if the amount of air moving per unit time is defined as "unit air volume", it is realized by setting (unit air volume blown out outside) ≤ (unit air volume sucked out inside) .
同軸二重構造を持ったプロペラファンにより、内側と外側の羽が同じ方向に回転するが、内側は空気を吸い込み、外側は空気を吹き出す構造にすると、竜巻状の風の流れが内側と外側とで同じ方向に回転しながら、吹き出した空気が外に拡散せずに内側の吸引する側に折り返す事により、安定かつ効率よく空気を竜巻状に吸引する事ができる。 A propeller fan with a coaxial double structure rotates the inner and outer wings in the same direction, but if the structure is such that the inside sucks in air and the outside blows out air, the tornado-shaped wind flow will flow between the inside and outside. While rotating in the same direction, the blown air does not diffuse to the outside but is folded back to the inside suction side, so that the air can be sucked in a tornado shape stably and efficiently.
図１の１はモーター等の回転の動力を伝えるファンの中心部、２は内側の羽、３は内側と外側を区切る境界部、４は外側の羽、５は外側の羽の方向を誘導する境界部、６はファンの回転方向をそれぞれ示す。 1 in FIG. 1 is the center of a fan that transmits the rotational power of a motor or the like, 2 is the inner wing, 3 is the boundary that separates the inner and the outer, 4 is the outer wing, and 5 is the outer wing. The boundary portion and 6 indicate the rotation direction of the fan, respectively.
この動作としては、このファンが図１の上から見た際に６に示す方向にモーターやエンジンにより回転駆動させると、外側は４の羽によって第１図の下から上に空気が吹き出し、同時に２の内側の羽は空気が上から下に吸引される。この時、単位時間当たりに動く空気の量を「単位風量」と定義すると、（外側の吐き出す単位風量）≦（内側の吸い出す単位風量）とする様にしている。 In this operation, when the fan is rotationally driven by a motor or engine in the direction shown in FIG. 1 when viewed from above in FIG. 1, air is blown from the bottom to the top in FIG. 1 by the wings of 4 on the outside, and at the same time. Air is sucked from the top to the bottom of the inner wings of 2. At this time, if the amount of air moving per unit time is defined as "unit air volume", (unit air volume discharged outside) ≤ (unit air volume sucked out inside).
この事により、空気は４の外側の羽により図１の上方向に６と同じ方向に渦を持った風を吹き出し、２の内側の羽により同じく６と同じ方向の渦となった竜巻状となって図１の上から下に吸い込まれる事になる。 As a result, the air blows a wind with a vortex in the same direction as 6 in the upward direction of FIG. 1 by the outer blades of 4, and becomes a tornado shape in the same direction as 6 by the inner blades of 2. It will be sucked from the top to the bottom of Fig. 1.
また、３の境界部は内側の風と外側の風を隔てると同時に、内側の吸い出す風の方向を誘導する役目があり、５の境界部は３の境界部と共に、外側の風の吹き出す向きを誘導する目的がある。この３と５の境界部と上記単位風量を適正化する事で、外側の風が筒状あるいはスカート状に渦を巻いたエアーカーテンとなり空間を分断する。そして、内側の風がその外側に吐き出された空気を同じく渦状に吸い込む流れとなる事から、空気の流れがスムーズになり、結果として内側のファンが安定的に強く吸い込む事が可能となる。 In addition, the boundary of 3 separates the inner wind from the outer wind, and at the same time, has the role of guiding the direction of the inner wind to be sucked out. There is a purpose to guide. By optimizing the boundary between 3 and 5 and the unit air volume, the outer wind becomes an air curtain that swirls in a tubular or skirt shape, and divides the space. Then, since the inner wind becomes a flow that sucks the air discharged to the outside in the same spiral shape, the air flow becomes smooth, and as a result, the inner fan can suck in stably and strongly.
この様に、ファンの構造がシンプルであり、エアーカーテンにより限られたエリアで吸気ができる様になる。尚、外側の風や内側の風を内側と外側の仕切り板を斜めスカート状に拡げたり、逆に狭めたりする事で、外側の風と内側の風が同軸二重構造ファンの根本で折り返す流れを抑圧してエアーカーテンの流れを整え、または単位風量の大きさを変える事により、吸気するエリアや強さを意図的に決定する事ができる。 In this way, the structure of the fan is simple, and the air curtain makes it possible to take in air in a limited area. By expanding the outer wind and inner wind in a diagonal skirt shape on the inner and outer partition plates , or narrowing them on the contrary , the outer wind and inner wind are folded back at the root of the coaxial double structure fan. It is possible to intentionally determine the area and strength of intake air by suppressing the air curtain and adjusting the flow of the air curtain or changing the size of the unit air volume.
図２は本発明の第1の応用例であり、７は建物等の壁、８は外の空気を建物内に誘導するダクト、９は排気する空気を吐き出すダクト、１０は本発明のファン、１１はファンを駆動するモーター、１２は調理用のレンジ台、１３は外から吸入する空気の流れ、１４は排気する空気の流れをそれぞれ示す。 FIG. 2 is a first application example of the present invention, in which 7 is a wall of a building or the like, 8 is a duct that guides outside air into the building, 9 is a duct that discharges exhaust air, and 10 is a fan of the present invention. 11 is a motor for driving a fan, 12 is a cooking range table, 13 is a flow of air taken in from the outside, and 14 is a flow of air to be exhausted.
この応用例の動作としては、１２の調理用レンジ台から発生する湯気や煙を、１３の吸気と１４の排気の流れによって効率的に換気するものである。その為に、７で仕切られた建物の壁の外から、８と９のダクトで区切られた風の流れを、１１のモーターで回転駆動される１０の本発明のファンによって生成しているという一実施例である。これは、局所的に発生する悪臭や粉塵が広範囲に拡がる前に吸い出すと言った用途にも応用が考えられる。
The operation of this application example is to efficiently ventilate steam and smoke generated from 12 cooking microwave ovens by the flow of 13 intake air and 14 exhaust gas. Therefore, it is said that 10 fans of the present invention, which are rotationally driven by 11 motors, generate a wind flow separated by
図３は本発明の第２の応用例であり、１５はモーター等の駆動部を内蔵させた本発明のファン、１６はコンピューターサーバーの様な電気機器内の発熱体、１７はその筐体、１８は筐体内への吸気の流れ、１９は筐体外への排気の流れをそれぞれ示す。
FIG. 3 shows a second application example of the present invention, in which 15 is a fan of the present invention incorporating a drive unit such as a motor, 16 is a heating element in an electric device such as a computer server, and 17 is a housing thereof.
この応用例の動作としては、コンピューターサーバー内等で特に熱を発生するＣＰＵ部や電源部を局所的に冷却する動作を示すものであり、１７の筐体の中にある１６の発熱体の上に、１５のファンを設置して動作させる事で、１８の吸気と１９の排気という空気の流れを作る事が可能となり、局所的な発熱体だけの冷却を可能とするものである。 The operation of this application example shows an operation of locally cooling the CPU unit and the power supply unit that generate heat particularly in a computer server or the like, and is on the 16 heating elements in the 17 housings. By installing and operating 15 fans, it is possible to create an air flow of 18 intakes and 19 exhausts, and it is possible to cool only the local heating element.
従来は、筐体やシェルタ等の閉空間の中にある発熱する電子機器やエンジン等を冷却する場合、外部の空気を閉空間内に吸い込むか、または吐き出す冷却ファンにより一方向の風の流れを作る事で実現していた。しかし、本発明のファンを利用する事で、発熱体の熱をピンポイントで吸い出す様に容易に配置する事が可能となり、筐体やシェルタ等閉空間内の他のエリアへの不要な熱伝搬を防ぐ事ができ、効率的な冷却が可能となる。 Conventionally, when cooling an electronic device or engine that generates heat in a closed space such as a housing or shelter, a cooling fan that sucks in or discharges outside air into the closed space creates a one-way wind flow. It was realized by making it. However, by using the fan of the present invention, it is possible to easily arrange the heating element so as to suck out the heat in a pinpoint manner, and unnecessary heat transfer to other areas in the closed space such as the housing and shelter. Can be prevented and efficient cooling is possible.
図４は本発明の第２の応用例であり、２０は枯葉等の軽い廃棄物、２１は廃棄物を吸い取る吸気ダクト、２２は吐き出す風の流れ、２３は排気物を吸い取る風の流れ、２４は地面をそれぞれ示す。 FIG. 4 is a second application example of the present invention, in which 20 is a light waste such as dead leaves, 21 is an intake duct for sucking waste, 22 is a flow of air to be discharged, 23 is a flow of wind for sucking exhaust gas, and 24. Indicates the ground respectively.
この応用例の動作としては、２２の吹き出す空気と、２３の吸い取る空気の流れにより、竜巻状となった空気の流れによって空気を吸い取る事ができる為に、２１の吸気口を２４の床面に接触させない状態でも２０の廃棄物を吸い取る様な装置にも応用が考えられる。 As the operation of this application example, since the air can be sucked by the tornado-shaped air flow by the flow of the air blown out by 22 and the air sucked by 23, the intake port of 21 is set on the floor surface of 24. It can also be applied to a device that sucks up 20 wastes even when they are not in contact with each other.
これは、従来の掃除機とは全く別な発想の清掃設備を提供するものである。ちなみに、この場合の竜巻状の流れを作るには、２１のダクトの外側の出口と内側の入口には空気の流れを渦となる空気に回転する方向に誘導する為のガイド壁の様な仕組みが必要となる。また、本応用イメージには、本発明のファンは２１のダクトの先に設置しており、掃除機の様な廃棄物を収集する機構は記載していない。 This provides a cleaning facility with a completely different concept from the conventional vacuum cleaner. By the way, in order to create a tornado-shaped flow in this case, a mechanism like a guide wall for guiding the air flow in the direction of rotation to the vortex air at the outer outlet and the inner inlet of the 21 duct. Is required. Further, in this application image, the fan of the present invention is installed at the end of 21 ducts, and a mechanism for collecting waste such as a vacuum cleaner is not described.
以上の実施例は、図１に示したプロペラファンをベースに双方向の風を一つの回転駆動機の中で生成する構造として説明したが、換気扇等にはその他多くの種類の構造が存在する。具体的にはシロッコファン、斜流ファン、ターボファンといった物があるが、これらはすべてモーターやエンジン等の回転駆動によって実現されているので、その一つの回転動作の中で、内側と外側とで双方向の風の流れを生成する構造にする事で、上述した図１による効果と同様の効果を得る応用が可能となる。 The above embodiment has been described as a structure in which a bidirectional wind is generated in one rotary drive based on the propeller fan shown in FIG. 1, but there are many other types of structures such as a ventilation fan. .. Specifically, there are sirocco fans, mixed flow fans, turbo fans, etc., but since these are all realized by rotational drive of motors, engines, etc., in one rotational operation, inside and outside By adopting a structure that generates a bidirectional wind flow, it is possible to apply an effect similar to the effect shown in FIG. 1 described above.
