Description

【発明の詳細な説明】 本発明は空気調和装置（以下空調機という）等の空気吹
出口に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air outlet for an air conditioner (hereinafter referred to as an air conditioner).

空調機は冷房、暖房及びその他の目的からその一部に空
気吹出口を具えており、この吹出口は使用条件に合せて
その吹出方向を随意に変えられるようになっている。An air conditioner is partially equipped with an air outlet for cooling, heating, and other purposes, and the direction of the air outlet can be changed at will according to the conditions of use.

従来の空調機を第１図ないし第４図について説明する。A conventional air conditioner will be explained with reference to FIGS. 1 to 4.

第１図における大きな白抜きの矢印は吹出口から出てく
る空気の流れ方向を示す。The large white arrow in FIG. 1 indicates the direction of flow of air coming out of the outlet.

この空気の吹出方向を変える目的で、吹出口近辺に偏向
板が設けられている。A deflection plate is provided near the air outlet for the purpose of changing the direction of air blowing out.

即ち、上下方向には偏向板１、左右方向には偏向板２で
調整する。That is, the vertical direction is adjusted by the deflecting plate 1, and the horizontal direction is adjusted by the deflecting plate 2.

第４図で偏向板１の場合を示すと、偏向板１の上流側の
空気流れに対し、ある角度に傾げることによって、偏向
板１より下流側での空気流れの向きを変える。FIG. 4 shows the case of the deflection plate 1. By tilting the deflection plate 1 at a certain angle with respect to the air flow on the upstream side of the deflection plate 1, the direction of the air flow on the downstream side of the deflection plate 1 is changed.

偏向板断面形状は図示するような上下対称の翼形断面、
或いは平な薄板及び厚板等である。The cross-sectional shape of the deflection plate is a vertically symmetrical airfoil cross-section as shown in the figure.
Alternatively, it may be a flat thin plate or a thick plate.

また、偏向板１．２を傾げる機構は第２図、第３図に示
すように回転軸３及び４を具える。The mechanism for tilting the deflection plate 1.2 also includes rotating shafts 3 and 4, as shown in FIGS. 2 and 3.

また、図示するように上下方向、左右方向夫々について
複数枚の偏向板１及び２があるが、各方向毎に一部また
は全部の偏向板を連動させるものもあるし、１枚づつ単
独に調整するものもある。Also, as shown in the figure, there are a plurality of deflection plates 1 and 2 for each of the vertical and horizontal directions, but there are some that interlock some or all of the deflection plates for each direction, and others that are adjusted individually one by one. Some do.

従来の空調機の欠点を第４図により上下方向偏向板１を
例に説明する。The drawbacks of conventional air conditioners will be explained using FIG. 4 using the vertical deflection plate 1 as an example.

いま、偏向板１が収納される空気流路において、偏向板
１の上流側空気流れの方向を偏向板１のなす角度が小さ
い範囲では問題は左程ないが、成る角度以上になると、
５の領域のように、偏向板１の下流側に面したいわゆる
背面で流れが剥離し、偏向板１に沿って流れなくなる。Now, in the air flow path where the deflection plate 1 is housed, there is no problem as long as the angle the deflection plate 1 makes with the direction of the air flow on the upstream side of the deflection plate 1 is small, but if the angle exceeds the angle,
As in the region 5, the flow separates at the so-called back surface facing the downstream side of the deflection plate 1 and no longer flows along the deflection plate 1.

その為、下流側の実際の流れは６で示すように偏向板１
の傾き角よりも小さた角度の方向変化としかならず、更
に重要なことは、偏向板１で大きな圧力損失を生じ、一
般的には空気流量が減少する。Therefore, the actual flow on the downstream side is as shown by 6 at the deflection plate 1.
The change in direction is only an angle smaller than the inclination angle of .More importantly, a large pressure loss occurs in the deflection plate 1, and the air flow rate generally decreases.

更に、圧力損失増大は、一般的には騒音増大をもたらす
。Furthermore, increased pressure drop generally results in increased noise.

この欠点を空調機としてみるなら、室内におけるその設
置位置によって或いは室内温度分布、人体にとってのフ
ィーリングはとから吹出方向を上下、或いは左右に調整
するが、大抵の場合は第４図のような現象（左右方向に
ついても同様）となる。If we look at this drawback as an air conditioner, the blowing direction must be adjusted vertically or horizontally depending on its installation position in the room, the indoor temperature distribution, and the feeling for the human body, but in most cases, it is adjusted as shown in Figure 4. This phenomenon occurs (the same applies to the left and right directions).

例えば、肝腎の空調機吹出口正面から離れた場所へ空気
を送ろうとして、傾き角を犬にしても、傾き角はど流れ
方向が変らぬ上に、傾き角を太きくすればする程その方
向への流量は減少し不満足な状態となる。For example, if you try to send air to a place far away from the front of the air conditioner outlet, even if you set the inclination angle to a dog, the flow direction will not change, and the thicker the inclination angle, the more The flow rate in this direction decreases and becomes unsatisfactory.

本発明は吹出方向を圧力損失が最小の装置から犬きく方
向を変えても、圧力損失がそれ程増大せず、しかも、調
整した方向に流れ方向が変るような吹出口を得ることを
目的とする。An object of the present invention is to obtain a blow-off outlet in which pressure loss does not increase significantly even if the blow-out direction is changed from a device with minimum pressure loss, and the flow direction changes in the adjusted direction. .

従来の上記欠点を除去した本発明の一実施例の構造を第
５図ないし第７図に示すと、先ず、第５図において、１
１，１２，１３，１４は吹出口の流路断面形状を保持す
る目的の剛部材で、材質は例えば軟鋼線材のようなもの
とするが目的を満足する限り特にこだわらない。The structure of an embodiment of the present invention, which eliminates the above-mentioned drawbacks of the conventional technology, is shown in FIGS. 5 to 7. First, in FIG.
Reference numerals 1, 12, 13, and 14 are rigid members for the purpose of maintaining the cross-sectional shape of the flow path of the outlet, and the material thereof is, for example, a mild steel wire, but is not particularly limited as long as it satisfies the purpose.

１５はこの吹出口を空調・機等べ取り付ける為のフラン
ジ部の芯となる剛部材で、材質は１１ないし１４と同じ
である。Reference numeral 15 designates a rigid member that serves as the core of the flange portion for attaching this outlet to an air conditioner, machine, etc., and is made of the same material as 11 to 14.

１６，１７，１８，１９は吹出口の方向を手等でもって
希望する方向へ向けた際、容易に降伏点を超えて塑性変
形するが、調整後は元へ戻そうとする吹出口自身の他の
部分の残留応力に抗して所定の方向を維持するものとす
る。16, 17, 18, and 19 are easily plastically deformed beyond the yield point when the outlet is turned in the desired direction by hand, etc., but after adjustment, the outlet itself tries to return to its original shape. The predetermined orientation shall be maintained against residual stress in other parts.

材質は、例えば１１ないし１４よりも細くした軟鋼線材
、極軟鋼線或いは鉛の細い棒材等が考えられる。The material may be, for example, a mild steel wire thinner than 11 to 14, a very soft steel wire, or a thin lead rod.

この１６ないし１９は１１ないし１４と交わる点で夫々
に固着される。These 16 to 19 are fixed at the points where they intersect with 11 to 14, respectively.

その手段は同材から溶接、異種材なら縛るか、ろう接等
その目的が達せられる限り特に選ばたい。The method should be selected as long as the purpose can be achieved, such as welding of the same materials, binding or soldering of dissimilar materials.

１またいし１９は空気の吹出口の骨組を構成する。The first orifice 19 constitutes the framework of the air outlet.

次に、第６図、第７図に示すように、上記の骨組を芯材
として被覆材２０で被覆し、吹出口流路の壁とフランジ
部を形成する。Next, as shown in FIGS. 6 and 7, the above framework is used as a core material and covered with a covering material 20 to form the wall and flange portion of the outlet flow path.

（フランジ部は、特に被覆されている必要はない）この
材料は、吹出口を希望する方向へ曲げた場合、各骨組材
で囲まれた板状の部分に着目すると、剪断力による犬き
た面内変形を受けるので、容易に弾性変形しうるような
ゴム状の物質とする必要がある。(The flange part does not need to be particularly coated.) When this material is bent in the desired direction, the plate-shaped part surrounded by each frame material will cause a dog-eared surface due to shearing force. Since it undergoes internal deformation, it must be made of a rubber-like material that can easily be elastically deformed.

具体的には、ゴム或いは極軟質塩化ビニルのような高分
子材料とすればよい。Specifically, a polymer material such as rubber or extremely soft vinyl chloride may be used.

本実施例の形状は、図示の如くフランジ部から吹出口先
端へ向って先細のテーパ状となっているが、これは射出
成形にて被覆するための考慮であって、別の製法に依る
ならテーパ状とは限らない。The shape of this example is tapered from the flange toward the tip of the outlet, as shown in the figure, but this is a consideration for covering by injection molding, and if another manufacturing method is used. It is not necessarily tapered.

また、フランジ部も取付方法によって決まる部分なので
別の取付方法を採用する場合、それに合った形状とすれ
ばよい。Furthermore, since the flange portion is also determined by the mounting method, if a different mounting method is used, it may be shaped to suit the mounting method.

また、断面形状も、四角形を図示しているが、本発明の
主旨が達成できる限り態形状としても何ら構わない。Moreover, although the cross-sectional shape is shown as a rectangle, it may have any shape as long as the gist of the present invention can be achieved.

次に、本発明の作用について述べると、先ず、第７図に
吹出口の方向が中立の位置にある場合の形状を示す。Next, to describe the operation of the present invention, first, FIG. 7 shows the shape when the direction of the air outlet is in a neutral position.

ここで白抜き矢印で示すのが空気の流れ方向である。Here, the direction of air flow is indicated by the white arrow.

吹出口中立方向では図面右上の矢印と図面左下の矢印の
方向とは一致している。In the neutral direction of the air outlet, the direction of the arrow at the top right of the drawing matches the direction of the arrow at the bottom left of the drawing.

吹出方向を上向きとしたい場合、吹出口を上に曲げると
、曲げる力を取除いた後も第８図に示すようにその向き
を自ら維持し空気流れは矢印の如く上向きとなる。If you want the blowout direction to be upward, bend the blowout port upward, and even after the bending force is removed, it will maintain its direction by itself, as shown in FIG. 8, and the air will flow upward as shown by the arrow.

尚ことで、本発明による吹出口の形状の変形の仕方の特
徴を記すと、例えば吹出口先端面（その近くに包み込ま
れている番号１１を考えてもよい）は、平行移動するだ
けで、面の回転は伴なわないことで、これは１６７”ｊ
いし１９でフランジ部と結合されているからである。Incidentally, to describe the characteristics of the method of deforming the shape of the air outlet according to the present invention, for example, the tip face of the air outlet (you may consider number 11 wrapped around it) simply moves in parallel, Since there is no rotation of the surface, this is 167"j
This is because the ring 19 is connected to the flange portion.

吹出方向を下向きにする場合は、第８図と逆の方向に曲
げればよい。If the blowing direction is directed downward, it may be bent in the opposite direction to that shown in FIG.

左右方向の調整は、同様にして第９図に示すようにすれ
ばよい。Adjustment in the left-right direction may be performed in the same manner as shown in FIG. 9.

第５図ないし第９図は吹出口が１箇の場合であるが、実
用上はそれでも充分利点の得られる用途もあるが、これ
を適用する用途め拡大を考えると、次のものが挙げられ
る。Figures 5 to 9 show cases where there is only one outlet, but there are still some applications where sufficient advantages can be obtained in practice, but when considering the expansion of applications to which this can be applied, the following can be mentioned. .

先ず、第１０図は上下に２箇連ねて一体成形したもので
、その効果は第１１図に示す如く上下別個の吹出方向が
得られる。First, as shown in FIG. 10, two parts are integrally molded in series, one above the other, and the effect is that separate blowing directions can be obtained for the upper and lower parts, as shown in FIG. 11.

尚これは、２箇と限らず用途に応じて連ねる筒数を増し
てもよい。Note that the number of cylinders is not limited to two, and the number of cylinders connected in a row may be increased depending on the purpose.

また、上下と同様に左右に連ねる場合も考えられる。Furthermore, it is also possible to connect them horizontally as well as vertically.

更に、上下と左右をまとめて、第１図の従来例を本発明
のものに置換えた実施例として第１２図に示す。Further, FIG. 12 shows an embodiment in which the conventional example shown in FIG. 1 is replaced with the present invention by combining the top and bottom and left and right sides.

この効果の大きさは、従来例では次のようた調整ができ
ぬことでも判る。The magnitude of this effect can be seen from the fact that the following adjustments cannot be made in the conventional example.

■ 例えば、吹出口左側では上向きに、中央では水平、
右側では下向きに吹出すことができる。■ For example, upwards on the left side of the outlet, horizontally in the center,
On the right side, you can blow out downwards.

２ 吹出空気を遠くへ飛ばす系統と、直前の吹下す系統
の２系統に分ける。2. Divided into two systems: one that blows out air far away, and one that blows it down just before.

即ち、上段と下段を第１１図に示すようにする。That is, the upper and lower stages are arranged as shown in FIG.

（従来例では、出来ぬことはないがあまり効果的でなく
、上下に広がった流れとたるだゆで、遠くへも届きにく
い。(With conventional methods, there is nothing that can be done, but it is not very effective, and the flow spreads vertically and drips, making it difficult to reach far.

）３ 全体の吹出方向とは別に、特定の限られた場所へ
スポット的に空気を送ることができる。)3 Apart from the overall blowing direction, air can be sent spot-wise to specific limited areas.

次に、吹出口流路断面形状を、円形としたものを第１３
図に示す。Next, the 13th
As shown in the figure.

尚、円形以外の形状としても伺ら構わない。Note that shapes other than circular may also be used.

更に、円形吹出口を２分割した例を第１４図に示す。Further, FIG. 14 shows an example in which the circular air outlet is divided into two parts.

本例は、第１３図の例も含め、自動車の室内への吹出口
に応用することが考えられる。This example, including the example shown in FIG. 13, may be applied to an air outlet into the interior of an automobile.

従来例に比較して次の効果が挙げられる。The following effects can be mentioned as compared to the conventional example.

１ 運転席あるいは助手席へ吹出す際、吹出方向が風量
減少なしに充分広くとれる。1. When blowing air to the driver's or passenger's seat, the blowing direction can be made sufficiently wide without reducing the air volume.

２ 例えば、運転席側に第１４図のもの１箇を具えるだ
けで、左側の口は運転者へ、右側の口は側方窓の曇り止
め用、または後席への送風用に使える。2. For example, by simply installing one of the devices shown in Figure 14 on the driver's seat side, the left opening can be used for the driver, and the right opening can be used to prevent fogging of the side windows or to blow air to the rear seats.

勿論、まとめて運転者へ向けても良い。以上述べたよう

、 １ 吹出口の方向を太きく変えても、空気流れの圧力損
失がそれ程大きくならたい。Of course, they may be directed at the driver all at once. As described above, the present invention provides a rigid member that maintains the cross-sectional shape of the air outlet flow path, a rigid member that attaches the air outlet, a member that maintains the fragmented flow path shape, and an attachment portion member that is fixed to each of the rigid members that maintain the cross-sectional shape of the air outlet flow path. (Easy to cover each of the above members as a core and change the blowing direction) (Easy to deform when changing the blowing direction) 1. Even if the direction of the air outlet is drastically changed, the pressure loss of the air flow should not be that large.

従って、空気流量もそれ程減少しない。Therefore, the air flow rate does not decrease much either.

２ 吹出口の方向を大きく変えても、空気流れはその方
向に良く追随する。2. Even if the direction of the air outlet is changed significantly, the air flow follows that direction well.

３ 装置の吹出口全体に、本発明の吹出口を複数箇設け
てやれば、（例えば第１２図）各吹出口毎に、隣接した
吹出口と干渉せぬ範囲で、独立して任意の方向に向ける
ことが出来、きめ細かな吹出方向の調整ができる。3 If a plurality of air outlets of the present invention are provided throughout the air outlet of the device (for example, Fig. 12), each air outlet can be independently operated in any direction as long as it does not interfere with adjacent air outlets. The blow direction can be finely adjusted.

４ 吹出口の向きを変えることが容易であると同時に、
与えられた向きを確実に保持する。4 It is easy to change the direction of the air outlet, and at the same time
Ensure that a given orientation is maintained.

５ 副次的効果として、被覆材として高分子材料を使用

が少なくなる。5 As a secondary effect, since a polymer material is used as the covering material, when blowing out cooling air, the covering material 15 acts as a heat insulating material due to its low thermal conductivity, preventing dew condensation on the outer surface of the outlet. It becomes less.

等の極めてすぐれた効果がある。It has extremely excellent effects.

本発明は高温にさらされるものを除いた空気調和装置一
般、ウィンドファン、自動車の室内換気用吹出口等に広
く用いられる。The present invention is widely used in general air conditioners other than those exposed to high temperatures, window fans, indoor ventilation outlets of automobiles, and the like.
