This button is pressed when starting the maintenance operation, which is a maintenance-related operation such as inspection and cleaning, i.e., the maintenance start button 75 for instructing the start of the cleaning operation, and pressed when the cleaning operation is completed, i.e., And a maintenance completion button 76 for instructing completion of the maintenance operation. In addition, the indoor unit 2 includes a receiving unit (not shown) for receiving an instruction signal transmitted from the remote controller 71. Since the remote controller 71 is provided with a maintenance start button 75 and a maintenance completion button 76, the user can easily recognize that maintenance is possible without looking at the instruction manual.
　なお、本実施の形態１では、リモートコントローラ７１に、お手入れ開始ボタン７５と、お手入れ完了ボタン７６とを備えている場合について説明するが、１つのボタンでお手入れの開始動作と完了動作を交互に送信する構成にしてもよい。そうすることで、リモートコントローラ７１のボタン数の削減を図ることができる。 In the first embodiment, a case will be described in which the remote controller 71 includes a maintenance start button 75 and a maintenance completion button 76. However, the maintenance start operation and the completion operation can be performed with one button. You may make it the structure which transmits alternately. By doing so, the number of buttons of the remote controller 71 can be reduced.
　また、メニュー項目の中にお手入れ開始機能、お手入れ完了機能を持たせ、選択操作により、信号を送信してもよい。また、お手入れ開始ボタン７５及びお手入れ完了ボタン７６の代わりにスイッチなどでもよい。また、例えば室内機２にお手入れ動作の開始を指示する手段を設けるなど、リモートコントローラ７１の代わりにお手入れ動作を指示する手段を設けてもよい。
　なお、リモートコントローラ７１は、本発明の「指示手段」に相当する。 Further, the menu item may have a maintenance start function and a maintenance completion function, and a signal may be transmitted by a selection operation. Further, instead of the maintenance start button 75 and the maintenance completion button 76, a switch or the like may be used. Further, for example, a means for instructing the start of the maintenance operation may be provided in place of the remote controller 71 such as a means for instructing the indoor unit 2 to start the maintenance operation.
The remote controller 71 corresponds to “instruction means” of the present invention.
　ユーザーが、空気調和機１が停止中に、リモートコントローラ７１のお手入れ開始ボタン７５を押すことにより、お手入れ動作の開始が指示され、制御装置７０はお手入れ動作を開始する。ここで、空気調和機１が運転中にお手入れ開始ボタン７５を押した場合は、制御装置７０はその操作、つまりお手入れ動作の開始の指示を受け付けず、無効操作として液晶画面７３に無効操作の表示をする。逆に言うと、制御装置７０は空気調和機１が運転停止時のみお手入れ開始ボタン７５の操作を受け付ける。これは、室内機２の運転中は室内送風機５が駆動しており、駆動中の室内送風機５にユーザーが触れたりするのを防止するため、お手入れできないようにしている。 When the user presses the maintenance start button 75 of the remote controller 71 while the air conditioner 1 is stopped, the start of the maintenance operation is instructed, and the control device 70 starts the maintenance operation. Here, when the air conditioner 1 presses the maintenance start button 75 during operation, the control device 70 does not accept the operation, that is, the instruction to start the maintenance operation, and the invalid operation is performed on the liquid crystal screen 73 as the invalid operation. Is displayed. In other words, the control device 70 accepts the operation of the maintenance start button 75 only when the air conditioner 1 is stopped. This prevents the user from touching the indoor blower 5 being driven and operating the indoor blower 5 to prevent the user from touching the driven indoor blower 5.
　なお、お手入れ開始ボタン７５を押すと強制的に運転を停止する仕様も可能ではあるが、誤操作による運転停止を防ぐことを目的として、本実施の形態１では、運転中のお手入れ開始ボタン７５の操作は無効操作としている。また、お手入れ動作の開始後は、お手入れ完了するまでお手入れ動作中であることを音、光などの報知手段で報知することで、ユーザーによる誤操作を抑制することができる。また、お手入れ動作中は他の動作を受け付けなくすることで、例えばお手入れ中に室内送風機５が駆動したりするのを防ぐことができる。なお、報知手段は例えばＬＥＤ、スピーカーなどであり、室内機２に設けてもよいし、リモートコントローラ７１に設けてもよい。 Although it is possible to forcibly stop the operation when the maintenance start button 75 is pressed, in the first embodiment, for the purpose of preventing the operation stop due to an erroneous operation, the maintenance start button 75 during operation is used. This operation is invalid. In addition, after the start of the cleaning operation, it is possible to suppress an erroneous operation by the user by notifying the user that the cleaning operation is in progress until the cleaning is completed using a notification means such as sound or light. Further, by not accepting other operations during the cleaning operation, for example, the indoor blower 5 can be prevented from being driven during the cleaning. The notification means is, for example, an LED or a speaker, and may be provided in the indoor unit 2 or in the remote controller 71.
　図５は、本発明の実施の形態１に係る空気調和機１の室内機２のお手入れ時を側面側から見た断面概略図である。

　また、複数の羽根部６０は、左右風向板連結棒６２、連結部６６、及び、左右風向板駆動用モータ連結棒６５によって、左右風向板駆動用モータ５４と連結している。そして、左右風向板駆動用モータ５４の回転により、左右風向板連結棒６２が左右に移動し、羽根部６０の向きを変更することができる。 Further, the plurality of blade portions 60 are connected to the left and right wind direction plate driving motor 54 by the left and right wind direction plate connecting rod 62, the connecting portion 66, and the left and right wind direction plate driving motor connecting rod 65. And by the rotation of the left and right wind direction plate driving motor 54, the left and right wind direction plate connecting rod 62 moves to the left and right, and the direction of the blade portion 60 can be changed.
　図９は、本発明の実施の形態１に係る空気調和機１の室内機２の左右風向板３６周辺の拡大図であり、図１０は、本発明の実施の形態１に係る空気調和機１の室内機２の吹出し口２２近傍の左右風向板３６を取り外した状態の外観図である。なお、ここでいう左右風向板３６を取り外した状態とは、図１０に示すように、左右風向板３６の一部が取り外されている状態であるものとする。
　左右風向板台座６１は、左右風向板３６を着脱する際に操作する左右風向板台座つまみ６３で固定されており、左右風向板台座つまみ６３には着脱操作方法６３ａが記載されている。この左右風向板台座つまみ６３は、上下風向板２８を室内機２から取り外すと露出するようになっている。つまり、上下風向板着脱機構部５６が外から見えるようになっている。 FIG. 9 is an enlarged view around the left and right wind direction plates 36 of the indoor unit 2 of the air conditioner 1 according to Embodiment 1 of the present invention, and FIG. 10 shows the air conditioner 1 according to Embodiment 1 of the present invention. It is an external view of the state which removed the right-and-left wind direction board 36 of the blower outlet 22 vicinity of the indoor unit 2 of this. Here, the state where the left and right wind direction plates 36 are removed is a state where a part of the left and right wind direction plates 36 is removed as shown in FIG.
The left and right wind direction plate pedestal 61 is fixed by a left and right wind direction plate pedestal knob 63 that is operated when the left and right wind direction plate 36 is attached and detached, and the left and right wind direction plate pedestal knob 63 describes an attaching / detaching operation method 63a. The left and right wind direction plate base knob 63 is exposed when the vertical wind direction plate 28 is removed from the indoor unit 2. That is, the up / down wind direction plate attaching / detaching mechanism 56 is visible from the outside.
　そして、着脱操作方法６３ａに記載された操作の方向に左右風向板台座つまみ６３を持って引くと、左右風向板台座６１が左右風向板台座回転軸６４（図８参照）を中心に回動し、左右風向板３６、つまり左右風向板台座６１が吹出し口２２の外へ移動する。
　なお、左右風向板台座つまみ６３は、本発明の「第二着脱機構部」に相当し、左右風向板台座回転軸６４は、本発明の「回転軸」に相当する。 When the left and right wind direction plate pedestal knob 63 is pulled in the direction of operation described in the attaching / detaching operation method 63a, the left and right wind direction plate pedestal 61 rotates about the left and right wind direction plate pedestal rotation shaft 64 (see FIG. 8). The left and right wind direction plates 36, that is, the left and right wind direction plate bases 61 move out of the outlet 22.
The left and right wind direction plate pedestal knob 63 corresponds to the “second attachment / detachment mechanism portion” of the present invention, and the left and right wind direction plate pedestal rotation shaft 64 corresponds to the “rotation shaft” of the present invention.
　以上の操作により、吹出し口２２に設けられた上下風向板２８及び左右風向板３６は容易に取り外すことができ、ケーシング背壁３９、ケーシング前壁４０、及び、室内送風機５のお手入れを行うことが可能となる。 By the above operation, the up-down wind direction plate 28 and the left-right wind direction plate 36 provided at the outlet 22 can be easily removed, and the casing back wall 39, the casing front wall 40, and the indoor blower 5 are cleaned. Is possible.
　ケーシング背壁３９、ケーシング前壁４０、及び、室内送風機５のお手入れが完了した後は、左右風向板３６を元に戻し、上下風向板２８を室内機２に取り付ける。上下風向板２８を取り付けた後、リモートコントローラ７１のお手入れ完了ボタン７６が押されると、制御装置７０は、お手入れ完了ボタン７６の操作を受け付ける。つまり、制御装置７０は、お手入れ動作の完了の指示を受け付ける。その後、上下風向板２８が停止状態（図３参照）に戻る。そして、お手入れ動作が完了したことを光、音などの報知手段で報知することで、お手入れ動作が完了したことをユーザーに知らせることができる。 After the cleaning of the casing back wall 39, the casing front wall 40, and the indoor blower 5 is completed, the left and right wind direction plates 36 are returned to their original positions, and the upper and lower wind direction plates 28 are attached to the indoor unit 2. When the maintenance complete button 76 of the remote controller 71 is pressed after the vertical wind direction plate 28 is attached, the control device 70 accepts the operation of the maintenance complete button 76. That is, the control device 70 receives an instruction to complete the care operation. Then, the up-and-down wind direction board 28 returns to a stop state (refer FIG. 3). The user can be informed that the cleaning operation is completed by notifying the user that the cleaning operation has been completed by using a notification means such as light or sound.
　また、上下風向板２８及び左右風向板３６が室内機２に取り付けられている状態でのみ制御装置７０が、お手入れ完了ボタン７６の操作を受け付ける、つまり、お手入れ動作の完了の指示を受け付けるようにするとよい。そうすることで、異常な状態、例えば上下風向板２８が取り付けられていない状態でお手入れ動作が完了するのを防ぐことができ、常に正常にお手入れ動作を完了させることができる。 In addition, the control device 70 accepts the operation of the maintenance completion button 76 only when the up / down wind direction plate 28 and the left / right wind direction plate 36 are attached to the indoor unit 2, that is, accepts an instruction to complete the maintenance operation. It is good to. By doing so, it is possible to prevent the maintenance operation from being completed in an abnormal state, for example, the state where the up-and-down wind direction plate 28 is not attached, and the maintenance operation can always be completed normally.
　なお、上下風向板２８及び左右風向板３６が室内機２に取り付けられていない状態でお手入れ完了ボタン７６が押されたら、上下風向板２８及び左右風向板３６を室内機２に取り付けるように光、音などの報知手段で報知する、または、液晶画面７３にその旨を表示するとよい。そうすることで、上下風向板２８及び左右風向板３６の付け忘れを防止することができる。 When the maintenance complete button 76 is pressed in a state where the up / down wind direction plate 28 and the left / right wind direction plate 36 are not attached to the indoor unit 2, the light is attached so that the up / down wind direction plate 28 and the left / right wind direction plate 36 are attached to the indoor unit 2. Informing means such as a sound, or displaying that on the liquid crystal screen 73 may be used. By doing so, it is possible to prevent forgetting to attach the up / down wind direction plate 28 and the left / right wind direction plate 36.
　上下風向板２８は、停止時には筐体２０の内部に収納されており、お手入れが完了した後の停止時に室内のほこりが堆積することはないが、上下風向板２８が筐体２０の内部に収納されない構成であっても、お手入れを行う手順が容易であることには変わりない。 The up-and-down wind direction plate 28 is housed inside the housing 20 at the time of stoppage, and indoor dust does not accumulate at the time of stop after maintenance is completed, but the up-and-down wind direction plate 28 is placed inside the housing 20. Even if the configuration is not stored, the procedure for cleaning is still easy.
　なお、一般に室内機２は高所に取り付けられることから、上下風向板２８を取り外す作業の実施中に、他者がリモートコントローラ７１を操作して不意に運転が開始することで、ユーザーが驚いて転落してしまう可能性がある。そこで、その予防のために、電源プラグ（図示せず）を抜いてからの作業を推奨しており、リモートコントローラ７１のお手入れ開始ボタン７５が押されると、上下風向板２８が回動するとともに、液晶画面７３には、「電源プラグをコンセントから抜いてください」というメッセージを表示して、電源プラグをコンセントから抜く操作をユーザーに促すことで、さらに安全性を高めることができる。 In general, since the indoor unit 2 is mounted at a high place, the user is surprised when another person operates the remote controller 71 and starts operation unexpectedly while the work for removing the vertical wind direction plate 28 is being performed. There is a possibility of falling. Therefore, to prevent this, it is recommended to work after unplugging the power plug (not shown). When the maintenance start button 75 of the remote controller 71 is pressed, the vertical wind direction plate 28 rotates. Further, by displaying a message “Please unplug the power plug from the outlet” on the liquid crystal screen 73 and prompting the user to unplug the power plug from the outlet, the safety can be further improved.
　なお、電源プラグを抜いてからの上下風向板２８の取り外し、左右風向板３６の取り外し、ケーシング背壁３９のお手入れ、ケーシング前壁４０のお手入れ、室内送風機５のお手入れ、左右風向板３６の取り付け、及び、上下風向板２８の取り付けに関する操作は、前述と同じであるが、電源プラグをコンセントに差すと、上下風向板２８が停止状態（図３参照）に戻るようにすることで、リモートコントローラ７１に設けたお手入れ完了ボタン７６による操作を廃止することができる。 In addition, after removing the power plug, the vertical wind direction plate 28 is removed, the left and right wind direction plates 36 are removed, the casing back wall 39 is cleaned, the casing front wall 40 is cleaned, the indoor blower 5 is cleaned, and the left and right wind direction plates 36 are removed. And the operation related to the attachment of the vertical wind direction plate 28 are the same as described above, but when the power plug is inserted into the outlet, the vertical wind direction plate 28 returns to the stopped state (see FIG. 3). The operation by the maintenance completion button 76 provided in the remote controller 71 can be abolished.
　以上より、本実施の形態１に係る空気調和機１の室内機２によれば、お手入れの作業を行う際には、ユーザーはリモートコントローラ７１のお手入れ開始ボタン７５を押す。そして、お手入れ開始ボタン７５が押下されたら、お手入れ動作が開始され、上下風向板２８の上下風向板着脱機構部５６、及び、着脱操作方法２８ａが記載された内側面が露出する。そのため、上下風向板２８の内側面に記載の着脱操作方法２８ａにしたがって上下風向板２８を取り外すことができる。 From the above, according to the indoor unit 2 of the air conditioner 1 according to Embodiment 1, the user presses the maintenance start button 75 of the remote controller 71 when performing the maintenance work. When the maintenance start button 75 is pressed, a cleaning operation is started, and the inner side surface on which the up / down air direction plate attaching / detaching mechanism portion 56 of the up / down air direction plate 28 and the attaching / detaching operation method 28a are described is exposed. Therefore, the vertical wind direction plate 28 can be removed according to the attaching / detaching operation method 28 a described on the inner surface of the vertical wind direction plate 28.
　また、上下風向板２８を室内機２から取り外すと、着脱操作方法６３ａが記載された左右風向板台座つまみ６３が露出するようになっている。そして、着脱操作方法６３ａに記載された操作の方向に左右風向板台座つまみ６３を持って引くと、左右風向板台座６１が左右風向板台座回転軸６４（図８参照）を中心に回動し、左右風向板３６、つまり左右風向板台座６１を吹出し口２２の外へ移動することができる。 Further, when the vertical wind direction plate 28 is detached from the indoor unit 2, the left and right wind direction plate base knob 63 on which the attaching / detaching operation method 63a is described is exposed. When the left and right wind direction plate pedestal knob 63 is pulled in the direction of operation described in the attaching / detaching operation method 63a, the left and right wind direction plate pedestal 61 rotates about the left and right wind direction plate pedestal rotation shaft 64 (see FIG. 8). The left and right wind direction plate 36, that is, the left and right wind direction plate base 61 can be moved out of the outlet 22.
　以上、上下風向板２８の内側面に記載された着脱操作方法２８ａ、及び、左右風向板台座つまみ６３に記載された着脱操作方法６３ａにしたがって、吹出し口２２に設けられた上下風向板２８、及び、左右風向板３６は容易に取り外すことができる。そして、ケーシング背壁３９、ケーシング前壁４０、及び、室内送風機５のお手入れを行うことが可能となる。そのため、室内機２の内部のお手入れの作業性を向上させることができる。 As described above, according to the attaching / detaching operation method 28a described on the inner surface of the up / down air direction plate 28, and the attaching / detaching operation method 63a described in the left / right air direction plate base knob 63, the up / down air direction plate 28 provided in the outlet 22; The left and right wind direction plates 36 can be easily removed. The casing back wall 39, the casing front wall 40, and the indoor blower 5 can be cleaned. Therefore, the workability of the inside of the indoor unit 2 can be improved.
　実施の形態２．

Therefore, a gap is formed between the adjacent support portions 33a.
　また、誘導部３３ｂは、筐体２０の長手方向に沿って延びており、上下方向について吹出し口２２から吹出される空気の風向を変更するものである。例えば、誘導部３３ｂが水平方向に傾いている場合は、支持部３３ａの隙間を通過する空気流を水平方向に誘導することができるため、正面吹きが可能となる。 Further, the guiding portion 33b extends along the longitudinal direction of the housing 20, and changes the air direction of the air blown from the blowout port 22 in the vertical direction. For example, when the guiding portion 33b is inclined in the horizontal direction, the airflow passing through the gap of the support portion 33a can be guided in the horizontal direction, and thus front blowing is possible.
　また、第二上下補助風向板３３は、第二上下補助風向板回転軸３５の回りを９０°以上回動することができる。
　なお、誘導部３３ｂは側面視して円弧形状のＲ面に限定されないが、平面よりも円弧形状のＲ面の方が風を誘導しやすくなる。また、誘導部３３ｂは、側面視して支持部３３ａに対して厳密に垂直に設けられていなくてもよい。 Further, the second vertical auxiliary wind direction plate 33 can be rotated by 90 ° or more around the second vertical auxiliary wind direction plate rotating shaft 35.
The guide portion 33b is not limited to the arc-shaped R surface when viewed from the side, but the arc-shaped R surface is easier to guide the wind than the flat surface. Further, the guide portion 33b may not be provided strictly perpendicular to the support portion 33a in a side view.
　図１２は、本発明の実施の形態２に係る空気調和機１の室内機２の運転時を側面側から見た断面概略図である。
　以下、本実施の形態２で追加された第一上下補助風向板３１、及び、第二上下補助風向板３３の機能について、図１２を用いて説明する。
　冷房運転時には冷気が直接ユーザーの体に当たるのを避けるために、一般に風向を水平吹きに設定するが、第一上下補助風向板３１がない場合、冷気によって前面パネル２３が冷やされてしまい、湿った室内空気が前面パネル２３に接触することで前面パネル２３に結露が生じ、結露水が水滴となって部屋を汚損する不具合が想定される。このため、実施の形態１では、水平吹きに対する風向の制約があるが、本実施の形態２では、この課題に対する改善した仕様を提示する。 FIG. 12 is a schematic cross-sectional view of the indoor unit 2 of the air conditioner 1 according to Embodiment 2 of the present invention as viewed from the side.
Hereinafter, functions of the first vertical auxiliary wind direction plate 31 and the second vertical auxiliary wind direction plate 33 added in the second embodiment will be described with reference to FIG.
In order to avoid the cold air directly hitting the user's body during the cooling operation, the wind direction is generally set to horizontal blowing, but when the first vertical auxiliary wind direction plate 31 is not provided, the front panel 23 is cooled by the cold air and becomes damp. It is assumed that the indoor air comes into contact with the front panel 23 to cause dew condensation on the front panel 23 and the dew condensation water becomes water droplets and soils the room. For this reason, in Embodiment 1, there is a restriction on the wind direction with respect to horizontal blowing, but in Embodiment 2, improved specifications for this problem are presented.
　第一上下補助風向板３１は、吹出し口２２から出る冷気により、空気流に対して上流側の面は冷却されるが、中空構造をとっており、断熱性を有するため、空気流に対して下流側の面で湿った室内空気が接触しても結露が生じない。また、吹出し口２２から出る冷気は、第一上下補助風向板３１によって吹出し口２２近傍の前面パネル２３の下部に直接接触するのを妨げられる。さらに、ケーシング前壁４０の下部である吹出し口２２近傍も、第一上下補助風向板３１によって冷風が直接接触するのを妨げられる。つまり、ケーシング前壁４０の第一上下補助風向板３１よりも前方部分が冷却されることがないため、熱伝導によってケーシング前壁４０に接している前面パネル２３が冷却されることがない。 The first up-and-down auxiliary wind direction plate 31 is cooled on the upstream side with respect to the air flow by the cold air coming out from the blowout port 22, but has a hollow structure and has heat insulation properties. Condensation does not occur even when wet indoor air comes into contact with the downstream surface. Further, the cold air coming out of the outlet 22 is prevented from directly contacting the lower portion of the front panel 23 in the vicinity of the outlet 22 by the first vertical auxiliary wind direction plate 31. Further, the cool air is prevented from coming into direct contact by the first vertical auxiliary wind direction plate 31 also in the vicinity of the air outlet 22 which is the lower part of the casing front wall 40. That is, since the front part of the casing front wall 40 is not cooled than the first vertical auxiliary wind direction plate 31, the front panel 23 in contact with the casing front wall 40 is not cooled by heat conduction.
　以上のように、第一上下補助風向板３１を設けることで、前面パネル２３は冷風の影響で冷やされることがなくなるので、前面パネル２３は周囲の空気と同程度の温度になり、前面パネル２３の結露を抑制することができる。 As described above, by providing the first vertical auxiliary wind direction plate 31, the front panel 23 is not cooled by the influence of the cold air, so the front panel 23 is at a temperature similar to the surrounding air, and the front panel 23. Condensation can be suppressed.
　第二上下補助風向板３３は、吹出し口２２から出る冷気を水平方向に変更する役割を担う。第一上下補助風向板３１は、前面パネル２３の結露を抑制する利点はあるが、冷気を垂直方向に変更してしまうため、第一上下補助風向板３１により垂直方向に変更された冷気を受ける位置に、第二上下補助風向板３３の誘導部３３ｂを配置することで、水平方向に変更することが可能となる。 The second up / down auxiliary wind direction plate 33 plays a role of changing the cold air coming out from the outlet 22 in the horizontal direction. The first up / down auxiliary wind direction plate 31 has an advantage of suppressing the condensation on the front panel 23, but changes the cold air in the vertical direction, and therefore receives the cold air changed in the vertical direction by the first up / down auxiliary wind direction plate 31. By arranging the guiding portion 33b of the second vertical auxiliary wind direction plate 33 at the position, it is possible to change in the horizontal direction.

FIG. 13 is a schematic cross-sectional view of the indoor unit 2 of the air conditioner 1 according to Embodiment 2 of the present invention when viewed from the side, and FIG. 14 relates to Embodiment 2 of the present invention. FIG. 15 is a schematic cross-sectional view of a state in which the up-and-down wind direction plate 28 is removed when cleaning the indoor unit 2 of the air conditioner 1 as seen from the side, and FIG. 15 is a diagram of the air conditioner 1 according to Embodiment 2 of the present invention. It is the perspective view which looked at the state which removed the left-right wind direction board 36 of the blower outlet 22 vicinity of the indoor unit 2 from the lower surface side.
　次に、本実施の形態２のお手入れ作業の手順について図１３－図１５を用いて説明する。
　なお、リモートコントローラ７１の構成については、実施の形態１と同じであるので説明を省略する。
　リモートコントローラ７１のお手入れ開始ボタン７５を押すと、制御装置７０はお手入れ開始ボタン７５の操作を受け付ける。その後、お手入れ動作が開始され、図１３に示す位置に、上下風向板２８、第一上下補助風向板３１、第二上下補助風向板３３の順に回動する。つまり、第一上下補助風向板３１、及び、第二上下補助風向板３３は可動範囲内で最前部に移動し、上下風向板２８は可動範囲内で最後部に移動する。
　次に、実施の形態１と同様の手順により上下風向板２８を取り外すと、図１４に示した状態になる。 Next, the procedure of the cleaning operation of the second embodiment will be described with reference to FIGS.
Note that the configuration of the remote controller 71 is the same as that of the first embodiment, and thus the description thereof is omitted.
When the maintenance start button 75 of the remote controller 71 is pressed, the control device 70 accepts the operation of the maintenance start button 75. Thereafter, a cleaning operation is started, and the upper and lower wind direction plates 28, the first upper and lower auxiliary wind direction plates 31 and the second upper and lower auxiliary wind direction plates 33 are rotated in the order shown in FIG. That is, the first up / down auxiliary wind direction plate 31 and the second up / down auxiliary wind direction plate 33 move to the foremost portion within the movable range, and the up / down air direction plate 28 moves to the rearmost portion within the movable range.
Next, when the vertical wind direction plate 28 is removed by the same procedure as in the first embodiment, the state shown in FIG. 14 is obtained.
　次に、実施の形態１と同様の手順により左右風向板３６を回動させると、図１５に示した状態になる。
　お手入れ開始ボタン７５が押下されたら、お手入れ動作が開始され、第一上下補助風向板３１及び第二上下補助風向板３３は、可動範囲内で最前部となる位置に移動する。つまり、左右風向板台座６１の回動軌跡よりも外側に移動しており、左右風向板３６の着脱の妨げにならない位置に移動している。そのため、第一上下補助風向板３１及び第二上下補助風向板３３を取り外す必要がなく、実施の形態１に比べて作業性を悪化させることなく、ケーシング背壁３９、ケーシング前壁４０、及び、室内送風機５のお手入れを行うことができる。 Next, when the left and right wind direction plates 36 are rotated by the same procedure as in the first embodiment, the state shown in FIG. 15 is obtained.
When the maintenance start button 75 is pressed, a cleaning operation is started, and the first vertical auxiliary wind direction plate 31 and the second vertical auxiliary wind direction plate 33 are moved to the frontmost position within the movable range. In other words, the left and right wind direction plate pedestal 61 has moved to the outside of the turning trajectory, and has moved to a position that does not hinder the attachment and detachment of the left and right wind direction plate 36. Therefore, it is not necessary to remove the first vertical auxiliary wind direction plate 31 and the second vertical auxiliary wind direction plate 33, and the casing back wall 39, the casing front wall 40, and the like without deteriorating workability compared to the first embodiment. The indoor fan 5 can be cared for.
　ケーシング背壁３９、ケーシング前壁４０、及び、室内送風機５のお手入れが完了した後は、左右風向板３６を元に戻し、上下風向板２８を室内機２に取り付ける。上下風向板２８を取り付けた後、リモートコントローラ７１のお手入れ完了ボタン７６が押されると、制御装置７０はお手入れ完了ボタン７６の操作を受け付ける。その後、第二上下補助風向板３３、第一上下補助風向板３１、上下風向板２８の順で停止状態、つまり、図１１に示す位置に戻る。 After the cleaning of the casing back wall 39, the casing front wall 40, and the indoor blower 5 is completed, the left and right wind direction plates 36 are returned to their original positions, and the upper and lower wind direction plates 28 are attached to the indoor unit 2. When the maintenance complete button 76 of the remote controller 71 is pressed after the vertical wind direction plate 28 is attached, the control device 70 accepts the operation of the maintenance complete button 76. Thereafter, the second vertical auxiliary wind direction plate 33, the first vertical auxiliary wind direction plate 31 and the vertical wind direction plate 28 are stopped in this order, that is, the position shown in FIG.
　以上より、本実施の形態２に係る空気調和機１の室内機２によれば、お手入れ動作が開始したら、第一上下補助風向板３１及び第二上下補助風向板３３は、左右風向板台座６１の回動軌跡よりも外側に移動しており、左右風向板３６の着脱の妨げにならない位置に移動する。そのため、第一上下補助風向板３１及び第二上下補助風向板３３を取り外す必要がなく、実施の形態１に比べて作業性を悪化させることなく、ケーシング背壁３９、ケーシング前壁４０、及び、室内送風機５のお手入れを行うことができる。 As described above, according to the indoor unit 2 of the air conditioner 1 according to the second embodiment, when the cleaning operation starts, the first vertical auxiliary wind direction plate 31 and the second vertical auxiliary wind direction plate 33 are the left and right wind direction plate bases. It moves to the outside of the rotation trajectory 61 and moves to a position that does not hinder the attachment / detachment of the left and right wind direction plates 36. Therefore, it is not necessary to remove the first vertical auxiliary wind direction plate 31 and the second vertical auxiliary wind direction plate 33, and the casing back wall 39, the casing front wall 40, and the like without deteriorating workability compared to the first embodiment. The indoor fan 5 can be cared for.
