Description

空気調和機Air conditioner
　本発明は、天井埋め込み型の空気調和機に関するものである。 The present invention relates to a ceiling embedded type air conditioner.
　室内の天井に埋め込まれて設置される天井埋め込み型の空気調和機には、室内の空気を吸込む吸込み口と、吸込み口から吸込んだ空気を吹出す吹出し口とが下方向に開口するように形成されているものがある。このような空気調和機には、吹出し口から吹出した空気が下方にいる人に直接当たること（いわゆるドラフト）を防止する機能や、天井の汚れ（いわゆるスマッジング）を抑制する機能を備えているものがある。 The ceiling-embedded air conditioner that is installed embedded in the ceiling of the room is formed so that the air inlet that sucks in indoor air and the outlet that blows out the air sucked from the air inlet open downward. There is something that has been. Such an air conditioner has a function of preventing the air blown from the blowout outlet from directly hitting a person below (so-called draft) and a function of suppressing ceiling dirt (so-called smudging). There is.
　ドラフトを防止する機能を備えるものとして、例えば特許文献１のような、吹出口に設けられた風向制御用ルーバを、運転開始時に大きく下降させることで、ドラフトを防止し、且つ天井面のスマッジングを抑制する空気調和機がある。 As what has the function which prevents a draft, the draft control is prevented by drastically lowering the wind direction control louver provided in the air outlet, for example, as disclosed in Patent Document 1, and the ceiling surface is smudged. There is an air conditioner to suppress.
特開２０１０－３２０６２号公報JP 2010-32062 A
　しかしながら、特許文献１に記載の空気調和機では、吹出口から大きく下降させたルーバのみによって風向を制御しているので、吹出口からルーバまでの間の風向は制御できなかった。したがって、吹出口から吹出された空気をルーバが確実に受け止められず、ドラフトを十分に防止できない可能性があった。
　また、特許文献１に記載の空気調和機では、化粧パネルの表面が吹出口から連続的に天井まで延びているので、吹出口から吹出された空気の一部が化粧パネルの表面に沿って天井まで達してしまい、天井面のスマッジングを十分に抑制できない可能性があった。 However, in the air conditioner described in Patent Document 1, since the wind direction is controlled only by the louver greatly lowered from the air outlet, the air direction from the air outlet to the louver cannot be controlled. Accordingly, there is a possibility that the louver cannot reliably receive the air blown out from the outlet and the draft cannot be sufficiently prevented.
Moreover, in the air conditioner described in Patent Document 1, since the surface of the decorative panel continuously extends from the air outlet to the ceiling, a part of the air blown out from the air outlet extends along the surface of the decorative panel. And the ceiling surface smudging may not be sufficiently suppressed.
　本発明は、このような事情に鑑みてなされたものであって、風向を制御しつつドラフトを防止することができる天井埋め込み型とされた空気調和機を提供することを目的とする。
　また、風向を制御しつつ天井のスマッジングを抑制することができる天井埋め込み型とされた空気調和機を目的とする。 This invention is made | formed in view of such a situation, Comprising: It aims at providing the air conditioner made into the ceiling embedding type which can prevent a draft, controlling a wind direction.
Moreover, it aims at the air conditioner made into the ceiling embedded type which can suppress the smudge of a ceiling, controlling a wind direction.
　上記課題を解決するために、本発明の空気調和機は以下の手段を採用する。
　すなわち、本発明の一態様に係る空気調和機は、吸込み口から吸込んだ空気を吹出し口から吹出す天井埋め込み型とされた空気調和機であって、前記吸込み口及び前記吹出し口が形成される本体部と、前記本体部に支持され、前記吹出し口近傍に配置されて前記吹出し口から吹出された空気の風向を調整するルーバと、前記本体部に支持され、前記ルーバが風向を調整した空気を所定の方向へ案内する案内部を有するフラップ機構と、を備え、前記案内部は、前記ルーバの近傍で前記吹出し口を閉鎖する第１位置と、前記吹出し口の下方であって前記ルーバによって風向を調整された空気を受け止める第２位置とを移動可能である。 In order to solve the above problems, the air conditioner of the present invention employs the following means.
That is, the air conditioner according to an aspect of the present invention is an air conditioner that is a ceiling-embedded type that blows out air sucked from a suction port from a blowout port, and the suction port and the blowout port are formed. A main body, a louver supported by the main body, disposed near the outlet, and configured to adjust a wind direction of air blown from the outlet; and an air supported by the main body and adjusted by the louver.

It is possible to move between the second position where the air whose air direction is adjusted is received.
　上記構成では、フラップ機構の案内部がルーバの近傍の位置である第１位置と吹出し口の下方に位置する第２位置とを移動可能である。したがって、案内部はルーバの近傍からルーバの風を受け止めやすい第２位置に容易に短距離で移動することができる。よって、ルーバからの空気を案内部が好適に受け止め、ドラフトを防止することができる。 In the above configuration, the guide portion of the flap mechanism can move between the first position, which is a position near the louver, and the second position, which is located below the outlet. Therefore, the guide unit can easily move in a short distance from the vicinity of the louver to the second position where the wind of the louver is easily received. Therefore, the air from the louver can be suitably received by the guide unit, and drafting can be prevented.
　また、上記構成では、吹出し口近傍にルーバが設けられ、吹出し口から吹出された空気の風向をルーバによって調整できるので、吹出された空気を所望の方向に送ることができる。 Further, in the above configuration, the louver is provided in the vicinity of the blowout port, and the wind direction of the air blown from the blowout port can be adjusted by the louver, so that the blown air can be sent in a desired direction.
　また、本発明の一態様に係る空気調和機は、前記本体部は、前記吹出し口に接続され、前記吹出し口から吹出された空気の下流方向へ天井に沿って延びるパネル部を有し、前記案内部は、前記パネル部に沿うとともに、少なくとも前記下流方向の端部である下流端部が前記パネル部よりも下方となる第３位置に移動可能であってもよい。 In the air conditioner according to an aspect of the present invention, the main body has a panel connected to the outlet and extending along a ceiling in a downstream direction of the air blown from the outlet. The guide portion may be movable to a third position along the panel portion, and at least a downstream end portion that is an end portion in the downstream direction is lower than the panel portion.
　上記構成では、フラップ機構の案内部がパネル部に沿っているので、案内部が第３位置に位置する場合、吹出し口から吹出された空気の一部は案内部の下面に沿って流れる。このとき、少なくとも案内部の下流端部はパネル部よりも下方となっているので、案内部の下面に沿って流れる空気は天井側へ流れにくい。したがって、天井近傍での空気の対流を抑制することができ、天井のスマッジングを抑制することができる。 In the above configuration, since the guide portion of the flap mechanism is along the panel portion, when the guide portion is located at the third position, a part of the air blown out from the outlet flows along the lower surface of the guide portion. At this time, since at least the downstream end portion of the guide portion is below the panel portion, the air flowing along the lower surface of the guide portion hardly flows to the ceiling side. Therefore, air convection in the vicinity of the ceiling can be suppressed, and ceiling smudging can be suppressed.
　また、本発明の一態様に係る空気調和機は、前記第３位置に位置する前記案内部の前記下流端部は、前記パネル部の前記下流方向の一端よりも前記下流方向側に位置してもよい。 Further, in the air conditioner according to one aspect of the present invention, the downstream end portion of the guide portion located at the third position is located closer to the downstream side than one end of the panel portion in the downstream direction. Also good.
　上記構成では、第３位置に位置する案内部の下流端部は、パネル部の下流方向の一端よりも下流方向側に位置している。よって、フラップ機構の案内部が第３位置に位置する場合、案内部の下面に沿って流れる空気は、より天井側へ流れにくくなる。これにより、パネル部の表面に沿って空気が流れることを防止することができる。したがって、天井近傍での空気の対流を確実に抑制することができ、天井のスマッジングを抑制することができる。 In the above configuration, the downstream end portion of the guide portion located at the third position is located on the downstream side of the downstream end of the panel portion. Therefore, when the guide part of the flap mechanism is located at the third position, the air flowing along the lower surface of the guide part is less likely to flow to the ceiling side. Thereby, it can prevent that air flows along the surface of a panel part. Therefore, air convection in the vicinity of the ceiling can be reliably suppressed, and ceiling smudging can be suppressed.
　また、本発明の一態様に係る空気調和機は、前記ルーバは、前記本体部に支持されるルーバ支持端部と前記ルーバ支持端部の他端である自由端部とを有し、前記ルーバ支持端部を支点として前記自由端部が上下移動可能であって、前記案内部は、前記吹出し口から吹出された空気の下流方向側の端部である下流端部と、前記下流端部の他端である上流端部とを有し、前記第２位置に位置する前記案内部の前記上流端部は、前記自由端部が最も下方に位置したときの前記ルーバの下方向延長線よりも前記下流方向に対して反対方向である上流方向側に位置してもよい。 Moreover, the air conditioner which concerns on 1 aspect of this invention WHEREIN: The said louver has a louver support end part supported by the said main-body part, and the free end part which is the other end of the said louver support end part, The said louver The free end can move up and down with a support end as a fulcrum, and the guide portion includes a downstream end that is an end on the downstream side of the air blown from the outlet, and a downstream end of the downstream end An upstream end that is the other end, and the upstream end of the guide portion that is located at the second position is lower than the downward extension line of the louver when the free end is located at the lowest position. You may locate in the upstream direction side which is an opposite direction with respect to the said downstream direction.
　上記構成では、第２位置に位置する案内部の上流端部は、自由端部が最も下方に位置したときのルーバの下方向延長線よりも上流方向側に位置する。よって、案内部が第２位置に位置する場合、ルーバの表面を沿って流れる空気は、案内部の上流端部よりも上流方向側から下方に流れることなく、案内部によって確実に受け止められる。したがって、空気調和機運転時のドラフトを確実に防止することができる。 In the above configuration, the upstream end portion of the guide portion located at the second position is located on the upstream side with respect to the downward extension line of the louver when the free end portion is located at the lowest position. Therefore, when the guide portion is located at the second position, the air flowing along the surface of the louver is reliably received by the guide portion without flowing downward from the upstream side of the upstream end portion of the guide portion. Therefore, it is possible to reliably prevent the draft during operation of the air conditioner.
　また、本発明の一態様に係る空気調和機は、前記フラップ機構は、前記本体部に固定される回転駆動部と、前記回転駆動部に支持される第１支持端部、及び該第１支持端部の他端である第１接続端部を有する第１アーム部と、前記第１接続端部に対して回転自由に接続された第２接続端部、及び該第２接続端部の他端であって前記案内部を支持する第２支持部を有する第２アーム部と、を備えていてもよい。 In the air conditioner according to an aspect of the present invention, the flap mechanism includes a rotation driving unit fixed to the main body, a first support end supported by the rotation driving unit, and the first support. A first arm portion having a first connection end which is the other end of the end portion; a second connection end portion rotatably connected to the first connection end portion; and other than the second connection end portion And a second arm portion having a second support portion that is an end and supports the guide portion.
　上記構成で、フラップ機構の案内部を移動させる場合、まず、回転駆動部が駆動し、第１支持端部を中心に第１アーム部を回転移動させる。第１アーム部が回転移動すると、第１アーム部に対して回転自由に接続された第２アーム部が移動し、これにより、第２アーム部に固定されている案内部が移動する。したがって、上記構成では、案内部の移動を１つの回転駆動部で行うことができるので、複数の駆動部を用いる場合に比べて、フラップ機構を簡素かつ安価なものにすることができる。 In the above configuration, when the guide portion of the flap mechanism is moved, first, the rotation driving portion is driven to rotate and move the first arm portion around the first support end portion. When the first arm portion rotates, the second arm portion that is freely connected to the first arm portion moves, and thereby the guide portion fixed to the second arm portion moves. Therefore, in the above configuration, the guide unit can be moved by one rotational drive unit, so that the flap mechanism can be made simpler and less expensive than when a plurality of drive units are used.
　また、本発明の一態様に係る空気調和機は、前記第１アーム部は、前記案内部が前記第２位置に位置するときに、鉛直下方向に延びるように位置していてもよい。 Further, in the air conditioner according to one aspect of the present invention, the first arm portion may be positioned so as to extend vertically downward when the guide portion is positioned at the second position.
　上記構成では、回転駆動部に支持される第１アーム部が鉛直下方向、すなわち重力方向に延びるように位置しているときに、案内部が第２位置に位置する。よって、回転駆動部が駆動していなくても、案内部を第２位置に位置させることができる。したがって、案内部を第２位置に位置させる構成を安価に実現できる。また、回転駆動部が故障等して、駆動できない状態であっても、自重により垂れ下げて案内部を第２位置に位置させることができ、ドラフトを防止することができる。 In the above configuration, the guide portion is positioned at the second position when the first arm portion supported by the rotation driving portion is positioned so as to extend vertically downward, that is, in the direction of gravity. Therefore, even if the rotation drive unit is not driven, the guide unit can be positioned at the second position. Therefore, the structure which positions a guide part in a 2nd position is realizable at low cost. Moreover, even if the rotation drive unit is in a state where it cannot be driven due to a failure or the like, the guide unit can be positioned at the second position by hanging down due to its own weight, and drafting can be prevented.
　本発明によれば、風向を制御しつつドラフトを防止することができる。
　また、風向を制御しつつ天井のスマッジングを抑制することができる。 According to the present invention, drafting can be prevented while controlling the wind direction.
Moreover, it is possible to suppress ceiling smudging while controlling the wind direction.

　以下に、本発明に係る一実施形態について、図面を参照して説明する。
　図１には、本実施形態に係る空気調和機１を斜め下方から見た斜視図が示されている。なお、図１ではフラップ機構１８（例えば図２参照）を省略して図示している。本実施形態に係る空気調和機１は、室内の天井３０に埋め込まれるように設置される天井埋め込み型空気調和機であって、図１に示されているように、本体部２を備えている。本体部２は、ユニット本体３とユニット本体３の下部に設けられるパネル本体４とを備え、パネル本体４には吹出し口１５が４つ設けられている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The perspective view which looked at the air conditioner 1 which concerns on this embodiment from diagonally downward is shown by FIG. In FIG. 1, the flap mechanism 18 (see, for example, FIG. 2) is omitted. The air conditioner 1 according to the present embodiment is a ceiling-embedded air conditioner that is installed so as to be embedded in an indoor ceiling 30, and includes a main body 2 as shown in FIG. . The main body 2 includes a unit main body 3 and a panel main body 4 provided below the unit main body 3, and the panel main body 4 is provided with four outlets 15.
　ユニット本体３は、天井３０内に設置される四方体形の下方が開口された箱体であり、内部の中心部位に設置されたターボファン５と、その周りを囲むように配置された四角形状に曲げ成形されている熱交換器６と、熱交換器６の下部に配置されたドレンパン７と、ドレンパン７の周囲壁とユニット本体３の内周面との間に形成された吹出し風路８と、ターボファン５の吸込み側に配置されたベルマウス９等を備えた構成とされている。なお、この空気調和機１は、室外機（図示省略）に対して液管およびガス管からなる２本の冷媒配管１０および電気配線１１を介して接続されることになる。 The unit body 3 is a box that is open in the lower side of a tetragonal shape installed in the ceiling 30, and has a turbofan 5 that is installed at the center of the inside, and a rectangular shape that is arranged so as to surround the periphery. A heat exchanger 6 that is bent, a drain pan 7 disposed below the heat exchanger 6, and a blowout air passage 8 formed between the peripheral wall of the drain pan 7 and the inner peripheral surface of the unit body 3. The configuration includes a bell mouth 9 and the like arranged on the suction side of the turbo fan 5. The air conditioner 1 is connected to an outdoor unit (not shown) through two refrigerant pipes 10 including a liquid pipe and a gas pipe and an electric wiring 11.
　ユニット本体３の下面を覆うように設置され、天井パネル、化粧パネルとも称されるパネル本体４は、略正方形状をなすパネルでとされている。パネル本体４には、中央部位に室内の空気を吸込むための開口である吸込み口１２が設けられており、その吸込み口１２には、吸込みグリル１３が設置されている。吸込みグリル１３は、グリル内面側にエアフィルタ（図示省略）が設置されている。このエアフィルタを交換あるいは清掃するため、パネル本体４に対して、エアフィルタを室内の床面近くまで降下されるように、ワイヤ１４、昇降モータ（図示省略）等が昇降自在に設置されている。なお、エアフィルタを自動清掃するため、エアフィルタ自動清掃機構を組み込んだ構成としてもよい。 The panel body 4, which is installed so as to cover the lower surface of the unit body 3 and is also called a ceiling panel or a decorative panel, is a panel having a substantially square shape. The panel body 4 is provided with a suction port 12, which is an opening for sucking indoor air, at a central portion, and a suction grill 13 is installed in the suction port 12. The suction grill 13 is provided with an air filter (not shown) on the inner surface side of the grill. In order to replace or clean the air filter, a wire 14, a lifting motor (not shown) and the like are installed so as to be movable up and down with respect to the panel body 4 so that the air filter is lowered to near the floor surface in the room. . In addition, in order to clean an air filter automatically, it is good also as a structure incorporating an air filter automatic cleaning mechanism.
　また、パネル本体４には、室内空気の吸込み口１２の周りを取り囲むように、パネル本体４の四辺に対応して４方向にそれぞれ吹出し口１５が設けられている。各吹出し口１５は、吸込み口１２から吸込んだ空気であって熱交換器６で冷却または加熱された空気が空調風として室内に吹出されるようになっている。 The panel body 4 is provided with outlets 15 in four directions corresponding to the four sides of the panel body 4 so as to surround the room air inlet 12. Each of the air outlets 15 is air sucked from the air inlet 12 and cooled or heated by the heat exchanger 6 to be blown into the room as conditioned air.
　また、パネル本体４は、パネル部１７を有している。パネル部１７は、吹出し口１５に接続されて吹出し口１５の外端から外側方向へ天井３０（図２参照）に沿って延びている。パネル部１７は、上面が天井３０に接していて、下面は下流方向へ行くにしたがって、パネル部１７の厚さを減少させるように湾曲している。 The panel body 4 has a panel portion 17. The panel unit 17 is connected to the blowout port 15 and extends along the ceiling 30 (see FIG. 2) from the outer end of the blowout port 15 toward the outside. The panel portion 17 has an upper surface in contact with the ceiling 30 and a lower surface curved so as to decrease the thickness of the panel portion 17 as it goes downstream.
　４方向の吹出し口１５近傍にそれぞれ１つずつルーバ１６が設けられている。４つのルーバ１６の構造は同一であるので、以下、１つのルーバ１６について説明する。ルーバ１６は、吹出し口１５から吹出された空気の吹出し方向（風向）を調整する。ルーバ１６の一端には、ルーバ用モータ（図示省略）に支持されるルーバ支持端部１６ａが設けられ、ルーバ１６の他端には、ルーバ支持端部１６ａの自由端部１６ｂが設けられている。ルーバ１６は、ルーバ用モータを介してパネル本体４に回転自在に支持されていて、所定の角度だけルーバ支持端部１６ａを中心に自由端部１６ｂが回転するように移動可能となっている。なお、４つのルーバ１６は、それぞれ個別独立に移動可能である。 One louver 16 is provided in the vicinity of each of the four-direction outlets 15. Since the structure of the four louvers 16 is the same, only one louver 16 will be described below. The louver 16 adjusts the blowing direction (wind direction) of the air blown from the blowing port 15. One end of the louver 16 is provided with a louver support end 16a supported by a louver motor (not shown), and the other end of the louver 16 is provided with a free end 16b of the louver support end 16a. . The louver 16 is rotatably supported by the panel body 4 via a louver motor, and is movable so that the free end portion 16b rotates about the louver support end portion 16a by a predetermined angle. The four louvers 16 can be moved individually and independently.
　また、４方向の吹出し口１５近傍には、それぞれ１つずつフラップ機構１８が設けられている。４つのフラップ機構１８の構造は同一であるため、以下、１つのフラップ機構１８について説明する。フラップ機構１８は、図２～図４に示されていますように、パネル本体４に固定されるモータ（回転駆動部）１９と、モータ１９に支持される第１アーム部２０と、第１アーム部２０に接続される第２アーム部２１と、第２アーム部２１に支持される案内部２２とを有する。フラップ機構１８の案内部２２は、ルーバ１６の近傍で吹出し口を閉鎖する第１位置（図２）と、吹出し口の下方であってルーバ１６によって風向を調整された空気を受け止める第２位置（図３）と、パネル部１７に沿うように外方に延びる第３位置（図４）とを移動可能である。 Further, one flap mechanism 18 is provided near each of the four-way outlets 15. Since the structure of the four flap mechanisms 18 is the same, only one flap mechanism 18 will be described below. As shown in FIGS. 2 to 4, the flap mechanism 18 includes a motor (rotation drive unit) 19 fixed to the panel body 4, a first arm unit 20 supported by the motor 19, and a first arm. It has the 2nd arm part 21 connected to the part 20, and the guide part 22 supported by the 2nd arm part 21. As shown in FIG. The guide portion 22 of the flap mechanism 18 has a first position (FIG. 2) that closes the outlet near the louver 16, and a second position that receives air whose wind direction is adjusted by the louver 16 below the outlet. 3) and a third position (FIG. 4) extending outward along the panel portion 17 are movable.
　第１アーム部２０の一端には、モータ１９に回転自在に支持される第１支持端部２０ａが設けられ、第１アーム部２０の他端には、第２アーム部２１と接続される第１接続端部２０ｂが設けられている。第１アーム部２０は、第１支持端部２０ａから第１接続端部２０ｂまで直線状に延びている。第２アーム部２１の一端には、第１アーム部２０に対して回転自由に接続される第２接続端部２１ａが設けられ、第２アーム部２１の他端には、案内部２２を支持する第２支持端部２１ｂが設けられている。第２アーム部２１は、第２接続端部２１ａから第２支持端部２１ｂまで直線状に延びている。案内部２２は、板状であって、ルーバ１６によって風向を調整された空気を所定の方向へ案内する。第１接続端部２０ｂと第２接続端部２１ａとの接続部分には、アクチュエータ等は搭載されておらず、第１アーム部２０が回転移動しても、第２アーム部２１は、重力によって略鉛直方向に延びる状態を維持する構成となっている。 One end of the first arm portion 20 is provided with a first support end portion 20 a that is rotatably supported by the motor 19, and the other end of the first arm portion 20 is connected to the second arm portion 21. One connection end 20b is provided. The first arm portion 20 extends linearly from the first support end portion 20a to the first connection end portion 20b. One end of the second arm portion 21 is provided with a second connection end portion 21a that is rotatably connected to the first arm portion 20, and the other end of the second arm portion 21 supports the guide portion 22. A second support end 21b is provided. The second arm portion 21 extends linearly from the second connection end portion 21a to the second support end portion 21b. The guide part 22 is plate-shaped and guides the air whose wind direction is adjusted by the louver 16 in a predetermined direction. An actuator or the like is not mounted on the connection portion between the first connection end portion 20b and the second connection end portion 21a. Even if the first arm portion 20 rotates and moves, the second arm portion 21 does not move due to gravity. It is the structure which maintains the state extended in a substantially perpendicular direction.
　上述したルーバ用モータ及びモータ１９は、サーボモータとされており、図示しない制御部によって駆動される。制御部は、ルーバ用モータ及びモータ１９の回転角度を得てその角度を所定のシーケンスに従って制御する。制御部は、例えば、ＣＰＵ（Central　Processing　Unit）、ＲＡＭ（Random　Access　Memory）、ＲＯＭ（Read　Only　Memory）、及びコンピュータ読み取り可能な記憶媒体等から構成されている。そして、各種機能を実現するための一連の処理は、一例として、プログラムの形式で記憶媒体等に記憶されており、このプログラムをＣＰＵがＲＡＭ等に読み出して、情報の加工・演算処理を実行することにより、各種機能が実現される。なお、プログラムは、ＲＯＭやその他の記憶媒体に予めインストールしておく形態や、コンピュータ読み取り可能な記憶媒体に記憶された状態で提供される形態、有線又は無線による通信手段を介して配信される形態等が適用されてもよい。コンピュータ読み取り可能な記憶媒体とは、磁気ディスク、光磁気ディスク、ＣＤ－ＲＯＭ、ＤＶＤ－ＲＯＭ、半導体メモリ等である。 The louver motor and motor 19 described above are servo motors and are driven by a control unit (not shown). The control unit obtains the rotation angle of the louver motor and the motor 19 and controls the angle according to a predetermined sequence. The control unit includes, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and a computer-readable storage medium. A series of processes for realizing various functions is stored in a storage medium or the like in the form of a program as an example, and the CPU reads the program into a RAM or the like to execute information processing / arithmetic processing. As a result, various functions are realized. The program is preinstalled in a ROM or other storage medium, provided in a state stored in a computer-readable storage medium, or distributed via wired or wireless communication means. Etc. may be applied. The computer-readable storage medium is a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like.
　次に、本実施形態のルーバ１６及びフラップ機構１８の動作について図２～図５を用いて説明する。なお、図３～図５に示されている二点鎖線は、運転停止時のルーバ１６の位置である。 Next, the operation of the louver 16 and the flap mechanism 18 of this embodiment will be described with reference to FIGS. 3 to 5 indicate the position of the louver 16 when the operation is stopped.
　図２は、空気調和機１が運転を停止している状態を示している。空気調和機１が運転を停止している状態では、図２に示されているように、モータ１９が同図において時計回り方向に駆動力を発揮した状態で第１アーム部２０を内側下方向に延びるように支持し、案内部２２が吹出し口１５を閉鎖する位置である第１位置に位置している。この時、ルーバ１６は、案内部２２の上方に位置していて、自由端部１６ｂが案内部２２の上面近傍に位置している。 FIG. 2 shows a state where the air conditioner 1 has stopped operating. In the state where the air conditioner 1 is stopped, as shown in FIG. 2, the first arm portion 20 is moved downward inward with the motor 19 exerting the driving force in the clockwise direction in FIG. The guide portion 22 is located at a first position which is a position where the outlet 15 is closed. At this time, the louver 16 is located above the guide portion 22, and the free end portion 16 b is located near the upper surface of the guide portion 22.
　空気調和機１の運転が開始され、案内部２２を第１位置から第２位置へ移動させる場合には、モータ１９は駆動力を徐々に減少させる。モータ１９の駆動力が徐々に減少すると、重力によって第１アーム部２０は同図において反時計回りに回転し、内側下方向に延びた状態から第１支持端部２０ａを中心に第１接続端部２０ｂが下方に移動するように回転移動し、モータ１９の駆動力がなくなると第１アーム部２０は鉛直方向に延びた状態となり、第２アーム部２１を介して第１アーム部２０に支持される案内部２２が第２位置に位置する（図３参照）。案内部２２の移動が完了すると、ルーバ用モータが駆動し、ルーバ１６がルーバ支持端部１６ａを中心に自由端部１６ｂが下方に向うように回転し、所定の位置まで移動する。第２位置に位置する案内部２２の内端（同図において左端）は、ルーバ１６の自由端部１６ｂが最も下方に位置したときのルーバ１６の下方向延長線Ｌ１よりも内側に位置している（図５参照）。なお、ルーバ１６の移動は、案内部２２の移動完了後でなくてもよく、案内部２２の移動と同時に行われてもよい。また、案内部２２は第２位置から第１位置にも移動可能である。その場合、フラップ機構１８は、上述した第１位置から第２位置への移動と逆の動作を行う。 When the operation of the air conditioner 1 is started and the guide unit 22 is moved from the first position to the second position, the motor 19 gradually decreases the driving force. When the driving force of the motor 19 is gradually reduced, the first arm portion 20 rotates counterclockwise in the drawing due to gravity, and extends from the inner downward direction to the first connecting end centering on the first support end portion 20a. When the driving force of the motor 19 disappears, the first arm portion 20 extends in the vertical direction and is supported by the first arm portion 20 via the second arm portion 21. The guided portion 22 is positioned at the second position (see FIG. 3). When the movement of the guide portion 22 is completed, the louver motor is driven, and the louver 16 rotates around the louver support end portion 16a so that the free end portion 16b faces downward, and moves to a predetermined position. The inner end (left end in the figure) of the guide portion 22 located at the second position is located on the inner side of the downward extension line L1 of the louver 16 when the free end portion 16b of the louver 16 is located at the lowest position. (See FIG. 5). The movement of the louver 16 may not be performed after the movement of the guide unit 22 is completed, and may be performed simultaneously with the movement of the guide unit 22. Moreover, the guide part 22 can be moved from the second position to the first position. In that case, the flap mechanism 18 performs an operation opposite to the movement from the first position to the second position described above.
　案内部２２を第２位置から第３位置へ移動させる場合には、モータ１９が駆動を開始する。モータ１９は、鉛直方向に延びた状態の第１アーム部２０を同図において反時計回りに回転させ、水平外側方向に延びた状態へと回転移動させる。第１アーム部２０が回転移動すると、第１アーム部２０に接続されている第２アーム部２１も移動し、第２アーム部２１に支持されている案内部２２が第３位置に移動する（図４参照）。第３位置に位置する案内部２２の外端は、パネル部１７の外端から鉛直下方向に延ばした線Ｌ２よりも外側に位置する。なお、案内部２２は第３位置から第２位置にも移動可能である。その場合、フラップ機構１８は、上述した第２位置から第３位置への移動と逆の動作を行う。 When moving the guide unit 22 from the second position to the third position, the motor 19 starts driving. The motor 19 rotates the first arm portion 20 in the state extending in the vertical direction counterclockwise in the drawing to rotate to the state extending in the horizontal outer direction. When the first arm portion 20 rotates, the second arm portion 21 connected to the first arm portion 20 also moves, and the guide portion 22 supported by the second arm portion 21 moves to the third position ( (See FIG. 4). The outer end of the guide portion 22 located at the third position is located outside the line L2 extending vertically downward from the outer end of the panel portion 17. The guide unit 22 can be moved from the third position to the second position. In that case, the flap mechanism 18 performs an operation opposite to the movement from the second position to the third position described above.
　次に、本実施形態の吹出し口１５から吹出された空気の流れについて説明する。
　案内部２２が図３のように第２位置に位置する場合、吸込み口１２から吸込まれた空気は、図３に矢印に示すように、吹出し口１５近傍でルーバ１６によって風向を調整される。ルーバ１６によって風向を調整された空気は、ルーバ１６の下方に位置する案内部２２の上面に受け止められ、案内部２２の延びる方向へ案内される。案内部２２が第３位置に位置する場合、図４に矢印で示すように、吹出し口１５から吹出された空気の一部は、吹出し口１５の外端からパネル部１７の下面の一部に沿うように流れた後、案内部２２の下面に沿って流れる。 Next, the flow of air blown out from the blowout port 15 of the present embodiment will be described.
When the guide portion 22 is positioned at the second position as shown in FIG. 3, the air direction of the air sucked from the suction port 12 is adjusted by the louver 16 in the vicinity of the blowout port 15 as indicated by an arrow in FIG. 3. The air whose wind direction has been adjusted by the louver 16 is received by the upper surface of the guide portion 22 located below the louver 16 and guided in the direction in which the guide portion 22 extends. When the guide portion 22 is located at the third position, as shown by an arrow in FIG. 4, a part of the air blown out from the blowout port 15 is transferred from the outer end of the blowout port 15 to a part of the lower surface of the panel portion 17. After flowing along, it flows along the lower surface of the guide portion 22.
　以上説明した本実施形態の空気調和機１が奏する作用及び効果について説明する。
　上記構成では、吹出し口１５近傍にルーバ１６が設けられ、吹出し口１５から吹出された空気の風向をルーバ１６によって調整できるので、吹出された空気を所望の方向に送ることができる。
　また、上記構成では、フラップ機構１８の案内部２２がルーバ１６の近傍の位置である第１位置と吹出し口１５の下方に位置する第２位置とを移動可能である。したがって、案内部２２はルーバ１６の近傍からルーバ１６の風を受け止めやすい第２位置に容易に短距離で移動することができる。よって、ルーバ１６からの空気を案内部２２が好適に受け止め、ドラフトを防止することができる。 The operation and effect of the air conditioner 1 of the present embodiment described above will be described.
In the above configuration, the louver 16 is provided in the vicinity of the blowout port 15 and the air direction of the air blown from the blowout port 15 can be adjusted by the louver 16, so that the blown air can be sent in a desired direction.
In the above configuration, the guide portion 22 of the flap mechanism 18 can move between the first position, which is a position near the louver 16, and the second position, which is located below the outlet 15. Therefore, the guide portion 22 can easily move from the vicinity of the louver 16 to the second position where the wind of the louver 16 is easily received at a short distance. Therefore, the air from the louver 16 can be suitably received by the guide unit 22, and drafting can be prevented.
　上記構成では、案内部２２が第３位置に位置する場合（図４参照）、吹出し口１５から吹出された空気の一部は案内部２２の下面に沿って流れる。このとき、案内部２２はパネル部１７よりも下方に位置しているので、案内部２２の下面に沿って流れる空気は天井３０側へ流れにくい。したがって、天井３０近傍での空気の対流を抑制することができ、天井３０のスマッジングを抑制することができる。 In the above configuration, when the guide unit 22 is located at the third position (see FIG. 4), a part of the air blown out from the outlet 15 flows along the lower surface of the guide unit 22. At this time, since the guide part 22 is located below the panel part 17, the air flowing along the lower surface of the guide part 22 hardly flows to the ceiling 30 side. Therefore, air convection in the vicinity of the ceiling 30 can be suppressed, and smudging of the ceiling 30 can be suppressed.
　上記構成では、第３位置に位置する案内部２２の外端部は、パネル部１７の外側方向の一端よりも外側に位置している。よって、フラップ機構１８の案内部２２が第３位置に位置する場合、案内部２２の下面に沿って流れる空気は、より天井３０側へ流れにくくなる。これにより、パネル部１７の表面に沿って空気が流れることを防止することができる。したがって、天井３０近傍での空気の対流を確実に抑制することができ、天井３０のスマッジングを抑制することができる。 In the above configuration, the outer end portion of the guide portion 22 located at the third position is located outside the one end of the panel portion 17 in the outer direction. Therefore, when the guide part 22 of the flap mechanism 18 is located at the third position, the air flowing along the lower surface of the guide part 22 is less likely to flow to the ceiling 30 side. Thereby, it is possible to prevent air from flowing along the surface of the panel portion 17. Therefore, air convection in the vicinity of the ceiling 30 can be reliably suppressed, and smudging of the ceiling 30 can be suppressed.
　上記構成では、第２位置に位置する案内部２２の内側端部は、図５に示したように、自由端部１６ｂが最も下方に位置したときのルーバ１６の下方向延長線Ｌ１よりも内側に位置する。よって、案内部２２が第２位置に位置する場合、ルーバ１６の表面を沿って流れる空気は、案内部２２の内側端部よりも内側から下方に流れることなく、案内部２２によって確実に受け止められる。したがって、空気調和機運転時のドラフトを確実に防止することができる。 In the above configuration, the inner end portion of the guide portion 22 located at the second position is located on the inner side of the downward extension line L1 of the louver 16 when the free end portion 16b is located at the lowest position, as shown in FIG. Located in. Therefore, when the guide portion 22 is located at the second position, the air flowing along the surface of the louver 16 is reliably received by the guide portion 22 without flowing downward from the inner end of the guide portion 22. . Therefore, it is possible to reliably prevent the draft during operation of the air conditioner.
　上記構成で、フラップ機構１８の案内部２２を移動させる場合、まず、モータ１９が駆動し、第１支持端部２０ａを中心に第１アーム部２０を回転移動させる。第１アーム部２０が回転移動すると、第１アーム部２０に対して回転自由に接続された第２アーム部２１が移動し、これにより、第２アーム部２１に固定されている案内部２２が移動する。したがって、上記構成では、案内部２２の移動を１つのモータ１９で行うことができるので、複数のモータを用いる場合に比べて、フラップ機構１８を簡素かつ安価なものにすることができる。 In the above configuration, when the guide portion 22 of the flap mechanism 18 is moved, the motor 19 is first driven to rotate the first arm portion 20 around the first support end portion 20a. When the first arm portion 20 rotates, the second arm portion 21 connected to the first arm portion 20 in a freely rotating manner moves, whereby the guide portion 22 fixed to the second arm portion 21 is moved. Moving. Therefore, in the above configuration, since the guide unit 22 can be moved by the single motor 19, the flap mechanism 18 can be made simple and inexpensive as compared with the case of using a plurality of motors.
　上記構成では、モータ１９に支持される第１アーム部２０が鉛直下方向、すなわち重力方向に延びるように位置しているときに、案内部２２が第２位置に位置する。したがって、モータ１９が駆動していなくても、案内部２２を第２位置に位置させることができる。したがって、案内部２２を第２位置に位置させる構成を安価に実現できる。また、モータ１９が故障等して、駆動できない状態であっても、自重により垂れ下げて案内部２２を第２位置に位置させることができ、ドラフトを防止することができる。 In the above configuration, when the first arm portion 20 supported by the motor 19 is positioned so as to extend vertically downward, that is, in the direction of gravity, the guide portion 22 is positioned at the second position. Therefore, even if the motor 19 is not driven, the guide portion 22 can be positioned at the second position. Therefore, the structure which positions the guide part 22 in the 2nd position is realizable at low cost. Further, even if the motor 19 is in a state where it cannot be driven due to a failure or the like, the guide portion 22 can be positioned at the second position by hanging down due to its own weight, and drafting can be prevented.
　なお、本実施形態では第１アーム部２０を駆動させる構成としてモータ１９を用いたが、第１アーム部２０を駆動させる構成はこれに限定されない。モータ１９以外のアクチュエータであってもよいし、手動で駆動できるものであってもよい。 In the present embodiment, the motor 19 is used as a configuration for driving the first arm unit 20, but the configuration for driving the first arm unit 20 is not limited to this. It may be an actuator other than the motor 19 or may be driven manually.
