Description
本発明は、空気吹出口に設けられた複数の風向板を備える風向変更装置及びこれを備えた空気調節装置に関するものである。 The present invention relates to a wind direction changing device including a plurality of wind direction plates provided at an air outlet and an air conditioning device including the same.
従来、空気調和機の室内ユニット等の吹出口には、特許文献１に示すように、風向を左右に変更するための風向変更装置が設置されている。風向変更装置は、吹出口の左右横方向にほぼ直交する回動軸まわりに回動自在とされた複数の風向板と、各風向板の羽根部下端部に形成された連結部に連結して風向板を連動回転させる連動杆とを備えている。 2. Description of the Related Art Conventionally, as shown in Patent Document 1, a wind direction changing device for changing a wind direction to the left and right is installed at an outlet of an indoor unit or the like of an air conditioner. The wind direction changing device is connected to a plurality of wind direction plates that are rotatable about a rotation axis that is substantially orthogonal to the left and right lateral direction of the air outlet, and a connecting portion formed at the lower end of the blade portion of each wind direction plate. It is equipped with an interlocking rod that rotates the wind direction plate in an interlocking manner.
上記風向変更装置においては、回動軸周りに平板状の風向板が回動するため、送風ファンから送り出された空気流は、風向板によって急激に方向を変更されることで空気流に乱れが生じ、空気吹出口から遠方までスムーズに空気流を吹き出すことが困難になる場合があった。 In the wind direction changing device, since the flat wind direction plate rotates around the rotation axis, the air flow sent from the blower fan is suddenly changed in direction by the wind direction plate so that the air flow is not disturbed. In some cases, it is difficult to smoothly blow an air flow from the air outlet to a distance.
上記問題を解決する風向変更装置として、特許文献２に示すように、軟質部と硬質部とからなる風向板を用いたものが知られている。この風向板の羽根部は、中間部分が軟質材料で形成された軟質部とされ、その両端部分が硬質材料で形成された硬質部とされ、一方の硬質部が風向板基部として吹出口を構成する壁面に固定され、他方の硬質部の側端部には連動杆を連結するための係止部材が形成されている。
特許文献２記載の風向変更装置においては、連動杆によって風向板に対して左右方向に力が加わったときには、軟質部が撓むことにより、羽根部全体として滑らかな曲面を形成するため、風向板に接触した空気流は、羽根部の曲面に沿ってスムーズに風向きを変更することが可能となり、空気吹出口から遠方まで効率よく空気流を吹出すことが可能となる。 In the wind direction changing device described in Patent Literature 2, when a force is applied to the wind direction plate in the left-right direction by the interlocking rod, the soft portion is bent to form a smooth curved surface as the entire blade portion. The air flow in contact with the air can smoothly change the direction of the wind along the curved surface of the blade, and the air flow can be efficiently blown from the air outlet to a distance.
しかしながら、上記構成の風向変更装置は、連動杆が羽根部の側端部に形成されているため、風向板の風向きを変更するためには、連動杆を吹出口の左右方向に大きく移動させることが必要となり、風向変更装置をコンパクト化することが困難になる上、風向板を所定の向きに変えるのに時間がかかっていた。 However, in the wind direction changing device configured as described above, the interlocking rod is formed at the side end portion of the blade portion. Therefore, in order to change the wind direction of the wind direction plate, the interlocking rod is greatly moved in the left-right direction of the outlet. Therefore, it is difficult to downsize the wind direction changing device, and it takes time to change the wind direction plate to a predetermined direction.
連動杆の位置については、特許文献１に示すように、羽根部の下端部に形成することも考えられる。しかし、この場合には、羽根部の下端部が連動杆に伴って左右方向に移動しても、羽根部に軟質部を形成していることにより、羽根部の上端部はあまり動かずに羽根部の上下方向で捩れが生じることになり、吹出口の左右方向に風向きを変更する風向変更装置として十分な性能を発揮できなくなるといった問題が生じる。 About the position of an interlocking rod, as shown in patent document 1, it is also considered to form in the lower end part of a blade | wing part. However, in this case, even if the lower end portion of the blade portion moves in the left-right direction along with the interlocking rod, the upper end portion of the blade portion does not move much because the soft portion is formed in the blade portion. Twist occurs in the up-and-down direction of the section, and there arises a problem that sufficient performance cannot be exhibited as a wind direction changing device that changes the wind direction in the left and right direction of the air outlet.
そこで、本発明においては、上記課題を解決するため、連動杆を吹出口の左右方向に大きく移動させることなく、風向板を短時間で所定の向きに変えることが可能で、かつ風向板の向きを変更したときに風向板の上下方向でねじれの生じにくい風向変更装置を提供することを目的とする。 Therefore, in the present invention, in order to solve the above-described problem, the wind direction plate can be changed to a predetermined direction in a short time without largely moving the interlocking rod in the left-right direction of the outlet, and the direction of the wind direction plate An object of the present invention is to provide a wind direction changing device that is less likely to be twisted in the vertical direction of the wind direction plate when the angle is changed.
上記問題点を解決するために、本発明では、複数の風向板が基板に取り付けられ、風向板を互いに連結して連動させる連動杆が設けられ、風向板は、羽根部と、該羽根部を支持して基板に固定される支持部とからなり、羽根部は、硬質部と、該硬質部の一側部に形成されて支持部に接続される軟質部とからなり、硬質部に貫通孔が形成され、各風向板の貫通孔に前記連動杆が挿通され、貫通孔内に形成された係止部に連動杆が回動自在に連結されたことを特徴とする。 In order to solve the above problems, in the present invention, a plurality of wind direction plates are attached to a substrate, and an interlocking rod for connecting and interlocking the wind direction plates to each other is provided. The wind direction plate includes a blade portion and the blade portion. The blade portion is composed of a hard portion and a soft portion formed on one side of the hard portion and connected to the support portion, and the through hole is formed in the hard portion. The interlocking rod is inserted into the through hole of each wind direction plate, and the interlocking rod is rotatably connected to a locking portion formed in the through hole.
上記構成によれば、羽根部の側端部よりも基部側寄りで、かつ羽根部の上下方向の中間に位置する貫通孔において連動杆を連結したため、連動杆の左右方向の移動量を少なくすることができ、風向板を短時間で所定の向きに変えることができるとともに、風向板の上下方向のねじれを抑制することが可能となる。 According to the above configuration, since the interlocking rod is connected in the through hole located closer to the base side than the side end of the blade portion and in the middle in the vertical direction of the blade portion, the amount of movement of the interlocking rod in the left-right direction is reduced. In addition, the wind direction plate can be changed to a predetermined direction in a short time, and the vertical twist of the wind direction plate can be suppressed.
本発明においては、硬質部に貫通孔を形成しているが、例えば、羽根部の周縁部から貫通孔の位置まで切り込みを形成することも考えられる。しかしながら、この場合には、軟質部を形成していることも相俟って羽根部の剛性が著しく低下し、羽根部が変形するおそれが生じることになる。 In the present invention, the through hole is formed in the hard part. However, for example, it is conceivable to form a cut from the peripheral part of the blade part to the position of the through hole. However, in this case, combined with the formation of the soft part, the rigidity of the blade part is significantly lowered, and the blade part may be deformed.
本発明における軟質部とは、連動杆の力によって撓むだけの可撓性を有していることが必要とされ、具体的な構成としては、例えば、硬質部を構成する硬質材料とは別の軟質材料で形成することができるほか、硬質部と同じ材料を用いて薄肉状に形成することで可撓性を付与することができる。これにより、軟質部を容易に形成することができる。 The soft part in the present invention is required to have flexibility enough to bend by the force of the interlocking rod. As a specific configuration, for example, it is different from the hard material constituting the hard part. In addition to being made of a soft material, it is possible to impart flexibility by forming it in a thin shape using the same material as the hard portion. Thereby, a soft part can be formed easily.
貫通孔内に形成された係止部に連動杆を回動自在に連結するには、具体的に、連動杆にＣ字状の軸受部を形成し、貫通孔内に係止部として支軸を設け、該支軸に軸受部を回動自在に軸支させることも可能であり、これにより、連動杆を貫通孔に挿通した状態で容易に連動杆を軸受部に連結することができる。 In order to connect the interlocking rod to the locking portion formed in the through hole so as to be rotatable, specifically, a C-shaped bearing portion is formed on the interlocking rod, and the support shaft is used as the locking portion in the through hole. It is also possible to pivotally support the bearing portion on the support shaft so that the interlocking rod can be easily connected to the bearing portion with the interlocking rod inserted through the through hole.
この場合、支軸の軸線方向は、硬質部と軟質部の境界線に沿って平行になるように形成することが好ましく、これによって、小さい力でスムーズに羽根部を湾曲させることができる。 In this case, the axial direction of the support shaft is preferably formed so as to be parallel along the boundary line between the hard portion and the soft portion, whereby the blade portion can be smoothly curved with a small force.
さらに、支軸の両端部にフランジ部を設けて、連結杆をフランジ部で支持させるようにすれば、連動杆と貫通孔壁とが直接的に接触することを防止することができる。したがって、連動杆と貫通孔壁との間で摩擦抵抗が発生するおそれがなく、連動杆を駆動させるモータに過負荷がかかることを防止することができるとともに、スムーズな風向変更が可能となる。 Furthermore, if a flange part is provided in the both ends of a spindle and a connection rod is supported by a flange part, it can prevent that an interlocking rod and a through-hole wall contact directly. Therefore, there is no possibility that a frictional resistance is generated between the interlocking rod and the through-hole wall, and it is possible to prevent an overload from being applied to the motor that drives the interlocking rod and to change the wind direction smoothly.
本発明に係る風向変更装置によれば、吹出口の左右方向に風向きを変更することが可能となるが、このほかに、回転軸方向が吹出口の左右横方向と平行になるように回転自在に枢支された横風向板を設けることもでき、これにより、空気流の風向きを上下方向に変更することが可能となる。 According to the wind direction changing device according to the present invention, it is possible to change the wind direction in the left-right direction of the air outlet, but in addition to this, it is freely rotatable so that the rotation axis direction is parallel to the left-right lateral direction of the air outlet. It is also possible to provide a horizontal wind direction plate pivotally supported by the air flow direction, whereby the wind direction of the air flow can be changed in the vertical direction.
本発明の風向変更装置は、各種の空気調節装置、例えば、空気調和機、空気清浄機、除湿機、加湿器、電気ヒータ、石油ストーブ、ガスヒータ及び冷蔵庫等に搭載することができる。 The wind direction changing device of the present invention can be mounted on various air conditioners such as an air conditioner, an air purifier, a dehumidifier, a humidifier, an electric heater, a petroleum stove, a gas heater, and a refrigerator.
以上のように、本発明によれば、硬質部と、硬質部の一側部に形成されて支持部に接続される軟質部とからなる羽根部を備えた風向板を使用し、硬質部に貫通孔を形成し、該貫通孔に連動杆を挿通した状態で、貫通孔内に形成された係止部に連動杆を回動自在に連結したため、連動杆を吹出口の左右方向に大きく移動させることなく、風向板を短時間で所定の向きに変えることが可能で、かつ風向板の向きを変更したときに風向板の上下方向でねじれの生じない風向変更装置を得ることができる。 As described above, according to the present invention, a wind direction plate having a blade portion including a hard portion and a soft portion formed on one side portion of the hard portion and connected to the support portion is used. With the through hole formed and the interlocking rod inserted in the through hole, the interlocking rod is pivotally connected to the locking part formed in the through hole, so the interlocking rod moves greatly in the left and right direction of the outlet Accordingly, it is possible to obtain a wind direction changing device that can change the wind direction plate in a predetermined direction in a short time and that does not twist in the vertical direction of the wind direction plate when the direction of the wind direction plate is changed.
本発明に係る実施形態を図面を基に説明する。本実施形態では、空気調節装置として空気調和機を用い、これに風向変更装置を搭載している。 An embodiment according to the present invention will be described with reference to the drawings. In this embodiment, an air conditioner is used as an air conditioner, and a wind direction changing device is mounted on the air conditioner.
空気調和機の室内ユニットを図１〜４に示す。室内ユニットは、熱交換器１および室内ファン２を備え、これらがキャビネット３に内装されている。キャビネット３は、高さよりも奥行きが長い箱状に形成され、前面から底面にかけて湾曲面とされる。キャビネット３の上面に吸込口４が形成され、湾曲面に吹出口５が形成される。 The indoor unit of an air conditioner is shown in FIGS. The indoor unit includes a heat exchanger 1 and an indoor fan 2, which are housed in a cabinet 3. The cabinet 3 is formed in a box shape having a depth longer than the height, and has a curved surface from the front surface to the bottom surface. A suction port 4 is formed on the upper surface of the cabinet 3, and an outlet 5 is formed on the curved surface.
キャビネット３の内部には、吸込口４から吹出口５に至る空気通路６が形成され、この空気通路６に熱交換器１と室内ファン２とが配設される。吸込口５と、熱交換器１との間にフィルタ７が配され、吸込口４から吸込んだ室内の空気から塵埃を除去する。このフィルタ７を清掃する清掃装置８が設けられる。 An air passage 6 extending from the suction port 4 to the blowout port 5 is formed inside the cabinet 3, and the heat exchanger 1 and the indoor fan 2 are disposed in the air passage 6. A filter 7 is disposed between the suction port 5 and the heat exchanger 1, and dust is removed from indoor air sucked from the suction port 4. A cleaning device 8 for cleaning the filter 7 is provided.
清掃装置８は、キャビネット３内でフィルタ７を移動させて、塵埃除去部９を通過させ、塵埃除去部９において、フィルタ７に付着した塵埃を除去する。キャビネット３内の前側に、側面視でＵ字形に湾曲した案内路１０が形成され、モータ、ギアからなる移動部が、フィルタ７を案内路１０に沿って往復移動させる。塵埃除去部９において、回転ブラシ１１により、通過するフィルタ７から塵埃を掻き取り、吸引ファンにより、フィルタ７と略平行方向（左右方向）に空気を流して、掻き取った塵埃を吸引して排出する。 The cleaning device 8 moves the filter 7 in the cabinet 3 to pass through the dust removing unit 9, and the dust removing unit 9 removes dust attached to the filter 7. A guide path 10 that is curved in a U shape in a side view is formed on the front side in the cabinet 3, and a moving unit including a motor and a gear reciprocates the filter 7 along the guide path 10. In the dust removing unit 9, the rotating brush 11 scrapes off dust from the passing filter 7, and a suction fan causes air to flow in a direction substantially parallel to the filter 7 (left and right direction), and the scraped dust is sucked and discharged. To do.
キャビネット３の湾曲面には、吹出口５を開閉する導風パネル２０が設けられる。図２〜４に示すように、導風パネル２０は、上下両開き可能とされ、導風パネル２０を移動させて開閉する開閉機構が設けられる。 An air guide panel 20 that opens and closes the air outlet 5 is provided on the curved surface of the cabinet 3. As shown in FIGS. 2 to 4, the wind guide panel 20 can be opened both up and down, and an opening / closing mechanism for moving the wind guide panel 20 to open and close is provided.
導風パネル２０は、湾曲した１枚のパネルによって形成され、キャビネット３の前面を覆う。導風パネル２０の幅は、キャビネット３の幅と同寸とされ、吹出口５の幅より大とされる。そして、キャビネット３の前面には、前面の中段部分から底面にかけて、一段低くなるように前パネル２１が形成される。これによって、幅方向全体に凹部が形成され、凹部に導風パネル２０が嵌るようになっている。凹部を形成する前パネル２１に開口が形成され、この開口が吹出口５である。そのため、導風パネル２０は、吹出口５よりも前方に位置することになり、吹出口５および吹出口５の周囲の前パネル２１を覆う。このとき、導風パネル２０は図２に示す閉姿勢となる。 The wind guide panel 20 is formed by a single curved panel and covers the front surface of the cabinet 3. The width of the wind guide panel 20 is the same as the width of the cabinet 3, and is larger than the width of the air outlet 5. And the front panel 21 is formed in the front surface of the cabinet 3 so that it may become one step lower from the middle part of the front surface to the bottom surface. Thereby, a recessed part is formed in the whole width direction, and the wind guide panel 20 fits into the recessed part. An opening is formed in the front panel 21 that forms the recess, and this opening is the air outlet 5. Therefore, the wind guide panel 20 is positioned in front of the air outlet 5 and covers the air outlet 5 and the front panel 21 around the air outlet 5. At this time, the wind guide panel 20 is in the closed position shown in FIG.
閉姿勢のとき、導風パネル２０の前端および後端とキャビネット３との間に隙間が形成される。図３，４に示すように、導風パネル２０が開閉するとき、導風パネル２０の端部がこの隙間に入り込む。導風パネル２０は、キャビネット３に当たらずにスムーズに回動できる。また、上開きあるいは下開きにおいて、導風パネル２０が最大に開いたとき、導風パネル２０がキャビネット３に接触するように、導風パネル２０の前後の端部を形成することにより、吹き出した風が漏れることを防げる。特に、冷風の場合には、キャビネット３の底面側での結露を防止できる。
このように、導風パネル２０の外面がキャビネット３の前面から底面に至る滑らかな湾曲面を構成する。すなわち、導風パネル２０が、キャビネット３の前面の一部を構成する部材となる。言い換えれば、キャビネット３のパネルの一部を導風パネル２０として利用する。これによって、導風パネル２０は、従来の空気調和機に採用されているルーバに比べて全長が長いロングパネルとなる。
When in the closed posture, a gap is formed between the front end and rear end of the wind guide panel 20 and the cabinet 3. As shown in FIGS. 3 and 4, when the wind guide panel 20 opens and closes, the end of the wind guide panel 20 enters this gap. The wind guide panel 20 can rotate smoothly without hitting the cabinet 3. Further, when the wind guide panel 20 is opened to the maximum in the upper opening or the lower opening, the front and rear ends of the wind guide panel 20 are formed so that the wind guide panel 20 contacts the cabinet 3. Prevents the wind from leaking. In particular, in the case of cold air, condensation on the bottom surface side of the cabinet 3 can be prevented.
Thus, the outer surface of the wind guide panel 20 constitutes a smooth curved surface extending from the front surface to the bottom surface of the cabinet 3. That is, the wind guide panel 20 is a member constituting a part of the front surface of the cabinet 3. In other words, a part of the panel of the cabinet 3 is used as the wind guide panel 20. Thereby, the wind guide panel 20 becomes a long panel having a long overall length as compared with the louver employed in the conventional air conditioner.
導風パネル２０は、上下の軸を中心にして、異なる方向に回動することにより、上下いずれかの方向に開く。図４に示すように、導風パネル２０は、冷房運転時には下軸２２周りに下開きする。この下開き姿勢のとき、導風パネル２０は、吹出口５の下壁とつながり、導風パネル２０と吹出口５の上壁とによってロングノズルが形成される。導風パネル２０は、冷風を斜め上方向に導き、冷風が天井に沿って吹き出す。図３に示すように、暖房運転時には上軸２３周りに上開きする。この上開き姿勢のとき、導風パネル２０は、吹出口５の前方を遮蔽し、前方に向かって吹き出される温風を押さえ込み、温風を床面方向に導く。なお、冷房運転の初期時にも、導風パネル２０は上開き姿勢とされ、冷風が床面方向に吹き出され、急速冷房が行われる。導風パネル２０は、図２に示すように、運転停止時には閉姿勢となり、吹出口５を覆って、キャビネット３と一体化する。 The wind guide panel 20 opens in either the upper or lower direction by rotating in different directions around the upper and lower axes. As shown in FIG. 4, the air guide panel 20 opens downward around the lower shaft 22 during the cooling operation. In this downward opening posture, the wind guide panel 20 is connected to the lower wall of the air outlet 5, and a long nozzle is formed by the air guide panel 20 and the upper wall of the air outlet 5. The wind guide panel 20 guides the cool air obliquely upward, and the cool air blows out along the ceiling. As shown in FIG. 3, it opens upward around the upper shaft 23 during heating operation. In this upward-opening posture, the air guide panel 20 shields the front of the air outlet 5, suppresses the warm air blown forward, and guides the warm air toward the floor surface. Even at the initial stage of the cooling operation, the air guide panel 20 is in the upwardly open posture, and the cool air is blown out in the direction of the floor surface to perform rapid cooling. As shown in FIG. 2, the wind guide panel 20 is closed when the operation is stopped, covers the air outlet 5, and is integrated with the cabinet 3.
なお、吹出口５には、風向変更装置１２および図示しない補助ルーバが設けられる。風向変更装置１２は、左右方向に風向板２４の角度を変えて、左右方向の風向きを変える。補助ルーバは、導風パネル２０の姿勢に応じて上下方向の角度を変え、吹き出される風を整流しながら上下方向の風向きを変える。 The air outlet 5 is provided with a wind direction changing device 12 and an auxiliary louver (not shown). The wind direction changing device 12 changes the wind direction in the left-right direction by changing the angle of the wind direction plate 24 in the left-right direction. The auxiliary louver changes the vertical direction according to the posture of the wind guide panel 20 and changes the vertical direction while rectifying the blown wind.
風向変更装置１２は、図５〜８に示すように、複数の風向板２４と、風向板２４が取り付けられる基板１３と、風向板２４を互いに連結して連動させる連動杆１４とを備えている。 As shown in FIGS. 5 to 8, the wind direction changing device 12 includes a plurality of wind direction plates 24, a substrate 13 to which the wind direction plates 24 are attached, and an interlocking rod 14 that links and links the wind direction plates 24. .
図５に示すように、基板１３は、細長いプレート状に形成されており、吹出口５に設置する際には、基板１３の長さ方向を吹出口５の左右方向Ａに合せるように、すなわち、基板１３の幅方向Ｂが吹出口５を流れる空気の流れ方向Ｃに対して平行になるようにセットされる。 As shown in FIG. 5, the substrate 13 is formed in an elongated plate shape. When the substrate 13 is installed in the air outlet 5, the length direction of the substrate 13 is aligned with the left-right direction A of the air outlet 5, that is, The substrate 13 is set so that the width direction B of the substrate 13 is parallel to the flow direction C of the air flowing through the outlet 5.
本実施形態では、風向板２４を、基板１３の右半分に位置する右側風向板群２５と、基板１３の左側半分に位置する左側風向板群２６とに区分し、各風向板群２５，２６に、風向板２４に連結して連動させる連動杆１４をそれぞれ別個に設けるようにしている。これにより、各風向板群２５，２６は、それぞれ独立して風向板２４の角度を調節して風向きを左右に変更可能とされている。 In the present embodiment, the wind direction plate 24 is divided into a right wind direction plate group 25 located in the right half of the substrate 13 and a left wind direction plate group 26 located in the left half of the substrate 13. In addition, the interlocking rods 14 that are connected to and interlocked with the wind direction plate 24 are separately provided. Thereby, each wind direction board group 25, 26 can adjust the angle of the wind direction board 24 independently, and can change a wind direction to right and left.
基板１３の左右方向両端部の裏面には、モータ２７，２７が設置されている。モータ２７には図示しない減速装置を介して駆動アーム２８が接続されており、駆動アーム２８の回転軸２８ｂ周りに揺動可能とされている。駆動アーム２８の先端部には、ピン２８ａが形成されており、このピン２８ａが連動杆１４に回転自在に連結され、駆動アーム２８の揺動により連動杆１４が左右方向に移動する。 Motors 27 are provided on the back surfaces of both ends of the substrate 13 in the left-right direction. A drive arm 28 is connected to the motor 27 via a speed reducer (not shown) so that the motor 27 can swing around the rotation shaft 28 b of the drive arm 28. A pin 28 a is formed at the tip of the drive arm 28, the pin 28 a is rotatably connected to the interlocking rod 14, and the interlocking rod 14 moves in the left-right direction when the drive arm 28 swings.
図８及び図９に示すように、風向板２４は、羽根部１５と、羽根部１５を支持して基板１３に固定される支持部１６とからなり、羽根部１５は、硬質部１５ａと、硬質部１５ａの一側部に形成されて支持部１６に接続される軟質部１５ｂとからなる。羽根部１５は、硬質部１５ａも軟質部１５ｂも同じ合成樹脂のポリプロピレンによって一体的に形成されており、硬質部１５ａの厚みt1が１．０ｍｍ、軟質部１５ｂの厚みt2が０．３ｍｍになるように形成されている。 As shown in FIGS. 8 and 9, the wind direction plate 24 includes a blade portion 15 and a support portion 16 that supports the blade portion 15 and is fixed to the substrate 13, and the blade portion 15 includes a hard portion 15a, The soft part 15b is formed on one side of the hard part 15a and connected to the support part 16. In the blade portion 15, both the hard portion 15a and the soft portion 15b are integrally formed of polypropylene of the same synthetic resin, the thickness t1 of the hard portion 15a is 1.0 mm, and the thickness t2 of the soft portion 15b is 0.3 mm. It is formed as follows.
このように、軟質部１５ｂは、硬質部１５ａよりも薄肉状に形成することにより、可撓性を備えている。風向板２４は、空気の流れ方向Ｃに沿って、支持部１６が上流側に、硬質部１５ａが下流側に配向するように、基板３上に固定される。なお、支持部１６も硬質部１５ａと同じ程度の厚みがあり、軟質部１５ｂのようにたわむことはない。 Thus, the soft part 15b is provided with flexibility by being formed thinner than the hard part 15a. The wind direction plate 24 is fixed on the substrate 3 along the air flow direction C so that the support portion 16 is oriented upstream and the hard portion 15a is oriented downstream. The support portion 16 has the same thickness as the hard portion 15a and does not bend like the soft portion 15b.
風向板２４において、硬質部１５ａの中央部やや下側には、長方形状の貫通孔２９が形成されており、貫通孔２９内の支持部１６寄りの位置には、連動杆１４を係止する係止部として支軸２９ａが形成されている。支軸２９ａは、その軸線方向Ｄが硬質部１５ａと軟質部１５ｂの境界線Ｅに沿って平行になるように形成されている。 In the wind direction plate 24, a rectangular through hole 29 is formed slightly below the central portion of the hard portion 15a, and the interlocking rod 14 is locked at a position near the support portion 16 in the through hole 29. A support shaft 29a is formed as a locking portion. The support shaft 29a is formed such that the axial direction D thereof is parallel to the boundary line E between the hard portion 15a and the soft portion 15b.
そして、支軸２９ａの両端部にはフランジ部２９ｂが形成されている。すなわち、フランジ部２９ｂにより、貫通孔２９の内壁と、支軸２９ａとの間に段差部が形成される。これにより、連動杆１４と、貫通孔壁とが直接的に接触することを防止するとともに、前述のごとく、連動杆１４と駆動アーム２８とが直接的に接触することも防止することで、スムーズな風向変更を可能としている。 And the flange part 29b is formed in the both ends of the spindle 29a. That is, a step portion is formed between the inner wall of the through hole 29 and the support shaft 29a by the flange portion 29b. As a result, the interlock rod 14 and the through hole wall are prevented from coming into direct contact with each other, and as described above, the interlock rod 14 and the drive arm 28 are also prevented from coming into direct contact with each other. The wind direction can be changed.
風向板２４の支軸２９ａに連結された連動杆１４が左右方向に移動すると、図１０に示すように、軟質部１５ｂが左右方向に湾曲して支持部１６及び羽根部１５全体として連続する緩やかな曲面を形成し、これによって空気流の方向をスムーズに変更することができる。 When the interlocking rod 14 connected to the support shaft 29a of the wind direction plate 24 moves in the left-right direction, as shown in FIG. 10, the soft portion 15b curves in the left-right direction and continues gently as the support portion 16 and the blade portion 15 as a whole. A smooth curved surface is formed, whereby the direction of air flow can be changed smoothly.
図１１及び図１２に示すように、支持部１６の基部１６ａは、基板１３に対して一方向にスライドして嵌合するように形成されている。具体的に、基板１３の幅方向Ｂの一端部には、風向板２４を固定するための切込部１７が複数形成されており、この切込部１７が形成された側が空気流れ方向Ｃの上流側になるようにして基板１３が吹出口５にセットされる。 As shown in FIGS. 11 and 12, the base portion 16 a of the support portion 16 is formed so as to slide and fit in one direction with respect to the substrate 13. Specifically, a plurality of cut portions 17 for fixing the wind direction plate 24 are formed at one end portion in the width direction B of the substrate 13, and the side on which the cut portions 17 are formed is in the air flow direction C. The board | substrate 13 is set to the blower outlet 5 so that it may become an upstream.
一方、支持部１６の基部１６ａは、切込部１７の長さと略同じ長さの細長いブロック状で、その両側部に、切込部１７の側壁をスライド可能に嵌入する溝部１９が形成された形状とされる。基部１６ａは、基板１３の側方から溝部１９を切込部１７に挿入してスライドさせることで基板１３に嵌合される。 On the other hand, the base portion 16a of the support portion 16 is an elongated block shape having a length substantially the same as the length of the notch portion 17, and groove portions 19 are formed on both sides thereof so that the side walls of the notch portion 17 are slidably fitted. Shaped. The base portion 16 a is fitted to the substrate 13 by inserting and sliding the groove portion 19 into the cut portion 17 from the side of the substrate 13.
図１３に示すように、連動杆１４は、細長い扁平棒状に形成されており、長さ方向の一端部を幅方向に折り曲げた略Ｌ字形状とされている。連動杆１４において、折り曲げた先端部及び幅方向の一端部には、複数のＣ字状の軸受部１４ａ及び１４ｂが形成されている。連動杆１４の先端部に形成された軸受部１４ａには、駆動アーム２８の先端に形成されたピン２８ａが連結され、連動杆１４の幅方向の一端部に形成された複数の軸受部１４ｂには、各風向板２４の支軸２９ａが連結される。 As shown in FIG. 13, the interlocking rod 14 is formed in an elongated flat bar shape, and has a substantially L shape in which one end portion in the length direction is bent in the width direction. In the interlocking rod 14, a plurality of C-shaped bearing portions 14 a and 14 b are formed at the bent tip portion and one end portion in the width direction. A pin 28a formed at the tip of the drive arm 28 is connected to the bearing 14a formed at the tip of the interlocking rod 14, and a plurality of bearings 14b formed at one end in the width direction of the interlocking rod 14 are connected to the bearing 14a. Are connected to the support shaft 29a of each wind direction plate 24.
連動杆１４を駆動アーム２８及び支軸２９ａに連結する際には、連動杆１４を各風向板２４の貫通孔２９に挿通した状態で、軸受部１４ａ及び１４ｂをピン２８ａ及び支軸２９ａに向けて押し込めばよい。これにより、容易に連動杆１４を駆動アーム２８及び支軸２９ａに連結することができる。 When connecting the interlocking rod 14 to the drive arm 28 and the support shaft 29a, the bearing portions 14a and 14b are directed to the pin 28a and the support shaft 29a in a state where the interlocking rod 14 is inserted into the through holes 29 of the wind direction plates 24. Just push in. Thereby, the interlocking rod 14 can be easily connected to the drive arm 28 and the support shaft 29a.
すなわち、従来は、特許文献１でも述べたように、風向板にはピンが突設され、連動杆にはピンに係合する係合孔が形成され、ピンの先端部には連動杆がピンから脱落するのを防止するストッパが形成されており、連動杆をピンに係合する際には、連動杆の係合孔をピンに無理嵌めしていた。したがって、風向板に無理な力がかかって変形するおそれがあった。特に、本発明では、風向板は軟質部を備えていることから、風向板が変形する可能性が高くなっていた。 That is, conventionally, as described in Patent Document 1, a pin is provided on the wind direction plate, an engagement hole that engages with the pin is formed on the interlocking hook, and the interlocking hook is provided at the tip of the pin. A stopper that prevents the interlocking rod from falling off is formed, and when the interlocking rod is engaged with the pin, the engaging hole of the interlocking rod is forcibly fitted to the pin. Therefore, there is a fear that the wind direction plate is deformed by an excessive force. In particular, in the present invention, since the wind direction plate has a soft part, there is a high possibility that the wind direction plate is deformed.
ところが、本発明に係る風向変更装置においては、上述のごとく、連動杆にＣ字状の軸受部を形成したことで軸受部を支軸に無理嵌めする必要がなくなり、風向板の変形を効果的に抑制することが可能となる。 However, in the wind direction changing device according to the present invention, as described above, the C-shaped bearing portion is formed in the interlocking rod, so that it is not necessary to force the bearing portion to be supported on the support shaft, and the deformation of the wind direction plate is effective. Can be suppressed.
なお、本実施形態においては、軸受部１４ａ及び１４ｂはＣ字状に形成されているが、連動杆１４は硬質部１５ａの中間部において支軸２９ａに連結されているため、風向板２４を左右方向に傾ける場合でもモータ２７の回転角度が小さくて済む（連動杆１４の移動量が少なくて済む）。したがって、ピン２８ａ及び支軸２９ａから軸受部１４ａ及び１４ｂが脱落するおそれがない。 In the present embodiment, the bearing portions 14a and 14b are formed in a C shape. However, since the interlocking rod 14 is connected to the support shaft 29a at the intermediate portion of the hard portion 15a, the wind direction plate 24 is moved to the left and right. Even when tilting in the direction, the rotation angle of the motor 27 can be small (the movement amount of the interlocking rod 14 can be small). Therefore, there is no possibility that the bearing portions 14a and 14b fall off from the pin 28a and the support shaft 29a.
また、連動杆１４は硬質部１５ａの下部よりも中間部に近い位置で支軸２９ａに連結されていることから、風向板２４を左右方向に傾ける場合でも羽根部１５の上部と下部とでねじれが発生する可能性を低減することができる。 Further, since the interlocking rod 14 is connected to the support shaft 29a at a position closer to the intermediate portion than the lower portion of the hard portion 15a, the upper and lower portions of the blade portion 15 are twisted even when the wind direction plate 24 is tilted in the left-right direction. It is possible to reduce the possibility of occurrence.
