Description

本発明は、吹き出し口を複数有する扇風機に関する。 The present invention relates to an electric fan having a plurality of outlets.

周知の如く、通常の扇風機は特許文献1に示されるように送風用の羽根車により一方向に送風する。 As is well known, an ordinary electric fan blows air in one direction by an impeller for blowing air as disclosed in Patent Document 1.

このような扇風機では通常羽根車の送風方向を可変にする機構を有し、広い範囲に送風できるのであるが、その範囲は概略180度の方向である。 Such a fan usually has a mechanism for changing the blowing direction of the impeller and can blow air over a wide range, but the range is a direction of approximately 180 degrees.

送風方向を広い範囲にするために、特許文献2の如く360度の方向に送風する扇風機も考案されている。 In order to make the blowing direction a wide range, a fan that blows in a direction of 360 degrees as in Patent Document 2 has been devised.

この他に、特許文献3または特許文献4の如く複数の方向に送風する扇風機も考案されている。 In addition, a fan that blows air in a plurality of directions as in Patent Document 3 or Patent Document 4 has been devised.

更に、特許文献5には複数の方向に吹き出し口を持つ撹拌送風用の構造が示されている。 Further, Patent Document 5 shows a structure for stirring air blowing having outlets in a plurality of directions.

しかしながらこのような扇風機では、以下に述べるような欠点がある。
(1)特許文献2の扇風機では、羽根車回転軸の方向回転機構が複雑になって、コストが高くなる。また、360度方向に送風できるものの、同時には一方向にのみしか送風できないという問題もある。
(2)特許文献3または特許文献4の如き扇風機では、同時に2方向に送風できるが、複数の羽根車とそれらを駆動するためのモーターが必要であり、コストが高くなり、かつサイズも大きなものになってしまうという欠点を免れない。
(3)特許文献5の構造では、ファンで発生した空気のうち複数の出口に流れるのは主流れの残りの一部を撹拌用に用いているに過ぎず、主の流れを複数にはできていない。
However, such a fan has the following drawbacks.
(1) In the electric fan of patent document 2, the direction rotation mechanism of an impeller rotating shaft becomes complicated, and cost becomes high. Moreover, although it can blow in a 360 degree direction, there also exists a problem that it can blow only in one direction simultaneously.
(2) A fan such as Patent Document 3 or Patent Document 4 can blow in two directions at the same time, but requires a plurality of impellers and a motor for driving them, which increases costs and is large in size. I cannot escape the disadvantage of becoming.
(3) In the structure of Patent Document 5, the air generated by the fan flows to the plurality of outlets only using the remaining part of the main flow for agitation, and the main flow can be made plural. Not.

そこで、本発明は上記のような問題点を解消した扇風機を提供すること目的とする。具体的には、
(1)本発明の第1の課題は、同時に複数の方向に送風できる扇風機を提供することである。
(2)本発明の第2の課題は、同時に複数の方向に、且つ概略全方向に送風できる扇風機を提供することである。
(3)本発明の第3の課題は、上記の如き扇風機を最小限の(実質的には単一の)羽根車で実現することである。
Therefore, an object of the present invention is to provide a fan that solves the above problems. In particular,
(1) The 1st subject of this invention is providing the electric fan which can blow in several directions simultaneously.
(2) The second problem of the present invention is to provide a fan capable of simultaneously blowing air in a plurality of directions and in almost all directions.
(3) A third object of the present invention is to realize the electric fan as described above with a minimum (substantially single) impeller.

第1及び第3の課題を解決するため、扇風機には複数の吐出口を設け、送風機の吐出部と前記吐出口の途中に分流機構を設けることにより、前記複数の吐出口から同時に送風できるように構成する。 In order to solve the first and third problems, the fan is provided with a plurality of discharge ports, and a diversion mechanism is provided in the middle of the discharge portion of the blower and the discharge port, so that air can be simultaneously blown from the plurality of discharge ports. Configure.

第2の課題を解決するための第1の手段は、前記吐出口付近に風向搖動機構を設けることである。 A first means for solving the second problem is to provide a wind direction swinging mechanism in the vicinity of the discharge port.

第2の課題を解決するための第2の手段は、複数の吐出口を有する前記扇風機を回転搖動機構で支持し、前記吐出口から吹き出される空気の風向を回転搖動させることである。 A second means for solving the second problem is to support the electric fan having a plurality of discharge ports with a rotary peristaltic mechanism, and to rotate and perturb the wind direction of the air blown from the discharge ports.

本発明の扇風機では、複数の送風機を用いず簡単な構造の分流機構を用いて扇風機の周囲にいる複数の人に同時に送風できるようにしたため、コンパクトで安価にでき、且つ消費電力も少なくできるという効果がある。 In the fan of the present invention, it is possible to simultaneously blow air to a plurality of people around the fan using a diverting mechanism with a simple structure without using a plurality of fans, so that it can be made compact and inexpensive and can reduce power consumption. effective.

図1に本発明による一実施例の外観図を示す。この構造を図2、図3の断面図を用いて詳述する。 FIG. 1 shows an external view of an embodiment according to the present invention. This structure will be described in detail with reference to the cross-sectional views of FIGS.

1は本発明による扇風機本体のケーシングである。該ケーシング(1)外壁には空気取入口(10)および空気吐出口(5a、5b)があり、またその内部にはファン(2)および導風板(3a、3b、3c、3d)により構成される導風部がある。ファン(2)はモーター(21)により駆動され、前記空気取入口(10)から空気を吸入して前記導風部を通り前記空気吐出口(50)から外部へ送風するようになっている。 Reference numeral 1 denotes a casing of a fan body according to the present invention. The casing (1) has an air inlet (10) and an air outlet (5a, 5b) on the outer wall, and is composed of a fan (2) and air guide plates (3a, 3b, 3c, 3d) inside the casing (1). There is a wind guide part. The fan (2) is driven by a motor (2 1), sucks air from the air intake (10), passes through the air guide section, and blows air from the air outlet (50) to the outside.

前記の空気の流れ(各図中に矢印で示してある)を詳述する。まず、前記導風部は前記のように導風板(3a、3b、3c、3d)により構成されており、前記ファン(2)部より、ケーシング(1)の上方左右に設けられた前記空気吐出口(5a、5b)空気を導く様になっている。前記空気取入口(10)から吸入され前記ファン(2)から吐き出された空気は、前記ファン(2)周囲の導風板(3a)により図の上方へ導かれ、更に、左右の導風板(3b、3c)の間を通って上方へ導かれ、前記上部導風板(3d)によって左右に分流される。前記の分流された空気は夫々左右の吐出口からほぼ左右反対向きに吐出される。
以上により本発明の第1の課題が達成される。すなわち、扇風機の左右両側にいる人々(図示していない)に風を送ることができる。
なお、本実施例では、前記の分流を確実に行うため、前記上部導風板(3d)のほぼ中央下部に分流版(4)が設けられている。前記分流版(4)は前記ケーシング(1)または前記上部導風板(3d)に適宜回転自由に取り付けられて角度を調整できるように構成することにより、左右の風量を調整可能になっている。
The air flow (indicated by arrows in each figure) will be described in detail. First, the air guide part is constituted by the air guide plates (3a, 3b, 3c, 3d) as described above, and the air provided on the left and right sides of the casing (1) from the fan (2) part. The discharge ports (5a, 5b) guide the air. The air sucked from the air inlet (10) and discharged from the fan (2) is guided upward in the figure by the air guide plate (3a) around the fan (2), and further, the left and right air guide plates. (3b, 3c) is guided upward and is divided into left and right by the upper air guide plate (3d). The divided air is discharged from left and right discharge ports in opposite directions.
As described above, the first object of the present invention is achieved. That is, the wind can be sent to people (not shown) on both the left and right sides of the fan.
In the present embodiment, in order to perform the above-described diversion reliably, a diversion plate (4) is provided substantially at the lower center of the upper air guide plate (3d). The diversion plate (4) is appropriately attached to the casing (1) or the upper air guide plate (3d) so that it can freely rotate and adjust the angle, thereby adjusting the air volume on the left and right. .

本実施例では、前記の左右の吐出口には夫々前記ケーシング(1)または前記上部導風板(3d)に回転可能なように変向板(51a、51b)が取り付けられており、吐出される空気の向きを変えられるようになっている。これにより、本発明の第2の課題が達成される。 In this embodiment, direction plates (51a, 51b) are attached to the right and left discharge ports so as to be rotatable on the casing (1) or the upper air guide plate (3d), respectively. You can change the direction of the air. Thereby, the second problem of the present invention is achieved.
