以下に図面を参照して本発明の実施形態を説明する。図1、図2は第1実施形態の空気調和機100の斜視図及び室内機1の正面図を示している。空気調和機100は室内機1及び室外機99から構成される。室内機1は室内の壁面Wに設置され、屋外に設置された室外機99に配管98により接続される。室内機1はリモートコントローラ(不図示)の操作により運転開始や運転停止等が指示される。以下の説明において、壁面Wに取り付けられる室内機1に向かって上側を上方、下側を下方、左側を左方、右側を右方、手前側を前方、奥側を後方とする。   Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a perspective view of the air conditioner 100 of the first embodiment and a front view of the indoor unit 1. The air conditioner 100 includes an indoor unit 1 and an outdoor unit 99. The indoor unit 1 is installed on a wall surface W in the room, and is connected to an outdoor unit 99 installed outdoors by a pipe 98. The indoor unit 1 is instructed to start or stop operation by operating a remote controller (not shown). In the following description, the upper side is the upper side, the lower side is the lower side, the left side is the left side, the right side is the right side, the front side is the front side, and the back side is the rear side, toward the indoor unit 1 attached to the wall surface W.

室内機1は着脱可能なフロントパネル3を前面に配した筐体2により外面を覆われる。筐体2の側面からは電源コード6が導出される。電源コード6は壁面Wに設けた電源コンセントCに接続され、室内機1に電力を供給する。   The interior of the indoor unit 1 is covered with a housing 2 having a front panel 3 that can be attached and detached arranged on the front surface. A power cord 6 is led out from the side surface of the housing 2. The power cord 6 is connected to a power outlet C provided on the wall surface W and supplies power to the indoor unit 1.

筐体2の上面には吸込口4が左右方向に延びて開口し、筐体2の前面下部の傾斜面上には吹出口5が左右方向に延びて開口する。   A suction port 4 extends in the left-right direction on the upper surface of the housing 2, and an air outlet 5 extends in the left-right direction on the inclined surface at the lower front of the housing 2.

図3は図2のA−A断面図を示している。筐体2の内部には吸込口4と吹出口5とを連通させる送風通路7が設けられる。送風通路7内には空気を送出する送風機9が配される。送風機9の駆動によって吸込口4から室内の空気が送風通路7に流入し、吹出口5から送出される。送風機9が備えるファンとしてはクロスフローファンが好適に用いられるが、他の種類の送風機9、例えばプロペラファンを有する送風機を用いてもよい。   FIG. 3 shows a cross-sectional view taken along the line AA of FIG. Inside the housing 2 is provided a blower passage 7 that allows the suction port 4 and the blowout port 5 to communicate with each other. A blower 9 that sends out air is disposed in the blower passage 7. Indoor air flows into the air passage 7 from the suction port 4 by driving the blower 9 and is sent out from the air outlet 5. A cross flow fan is preferably used as the fan included in the blower 9, but another type of blower 9, for example, a blower having a propeller fan may be used.

送風通路7内の吸込口4と送風機9との間には熱交換器8が配される。熱交換器8は冷凍サイクルに組み込まれており、室外機99に配した圧縮機(不図示)に接続される。   A heat exchanger 8 is arranged between the suction port 4 and the blower 9 in the blower passage 7. The heat exchanger 8 is incorporated in the refrigeration cycle and is connected to a compressor (not shown) disposed in the outdoor unit 99.

吹出口5には上下方向の風向を可変するルーバー10、ルーバー21及びルーバー22が設けられる。ルーバー10(第1ルーバー)は平板状に形成され、後端を中心に回動可能に設けられる。   The air outlet 5 is provided with a louver 10, a louver 21 and a louver 22 that change the wind direction in the vertical direction. The louver 10 (first louver) is formed in a flat plate shape and is provided so as to be rotatable around a rear end.

ルーバー22は平板状に形成され、ルーバー10の上方に配される。ルーバー21(第2ルーバー)はルーバー22に略平行な平板状に形成され、ルーバー22よりも前方に突出してルーバー22の上方に配される。ルーバー21及びルーバー22は鉛直な連結部20で連結され、後端を中心に一体に回動可能に設けられる。   The louver 22 is formed in a flat plate shape and is disposed above the louver 10. The louver 21 (second louver) is formed in a flat plate shape substantially parallel to the louver 22, protrudes forward from the louver 22, and is disposed above the louver 22. The louver 21 and the louver 22 are connected by a vertical connecting portion 20 and are provided so as to be integrally rotatable around a rear end.

また、吹出口5近傍の送風通路7の上壁7aには凹部7bが設けられる。凹部7bはルーバー21の厚みと略同じ深さに形成される。また、凹部7bの後壁7cはルーバー21の後端21aに近接する。   In addition, a recess 7 b is provided in the upper wall 7 a of the air passage 7 in the vicinity of the outlet 5. The recess 7b is formed to have a depth substantially equal to the thickness of the louver 21. The rear wall 7c of the recess 7b is close to the rear end 21a of the louver 21.

上記構成の空気調和機100において、送風機9を停止した送風停止時にルーバー10及びルーバー21は図3に示す原点位置に配置される。原点位置ではルーバー21が送風通路7の上壁7aに沿って凹部7b内に配され、ルーバー10がルーバー21の先端21cに当接して吹出口5を閉じる。   In the air conditioner 100 having the above-described configuration, the louver 10 and the louver 21 are disposed at the origin position shown in FIG. At the origin position, the louver 21 is disposed in the recess 7 b along the upper wall 7 a of the air passage 7, and the louver 10 abuts the tip 21 c of the louver 21 to close the outlet 5.

暖房運転または冷房運転が開始されると、圧縮機及び送風機9が駆動される。これにより、吸込口4から送風通路7に流入した空気が熱交換器8と熱交換し、吹出口5から室内にそれぞれ送出される。   When the heating operation or the cooling operation is started, the compressor and the blower 9 are driven. Thereby, the air which flowed into the ventilation path 7 from the suction inlet 4 heat-exchanges with the heat exchanger 8, and is sent out indoors from the blower outlet 5, respectively.

図4は暖房運転の開始時の吹出口5近傍を示す側面断面図である。暖房運転の開始時に空気調和機100は下方吹出し状態(第2送風状態)に設定される。下方吹出し状態ではルーバー10、ルーバー21及びルーバー22はそれぞれ略平行で前方を下方に向けて傾斜して配置される。これにより、吹出口5から下方に気流(温風)が吹き出され、室内が昇温される。   FIG. 4 is a side sectional view showing the vicinity of the air outlet 5 at the start of the heating operation. At the start of the heating operation, the air conditioner 100 is set in the downward blowing state (second blowing state). In the downward blowing state, the louver 10, the louver 21, and the louver 22 are arranged substantially in parallel and inclined forward and downward. As a result, an air flow (warm air) is blown downward from the outlet 5 and the temperature of the room is raised.

図5は冷房運転の開始時の吹出口5近傍を示す側面断面図である。冷房運転の開始時に空気調和機100は水平吹出し状態(第1送風状態)に設定される。水平吹出し状態ではルーバー10は水平に対して若干前方を下方に向けて傾斜して配置される。ルーバー21は送風通路7の上壁7aに沿って凹部7b内に配置され、ルーバー21及びルーバー22が略水平に配置される。これにより、吹出口5から略水平方向に気流(冷風)が吹き出され、室内が降温される。   FIG. 5 is a side sectional view showing the vicinity of the air outlet 5 at the start of the cooling operation. At the start of the cooling operation, the air conditioner 100 is set to a horizontal blowing state (first blowing state). In the horizontal blowing state, the louver 10 is disposed so as to be inclined slightly forward with respect to the horizontal. The louver 21 is disposed in the recess 7b along the upper wall 7a of the air passage 7, and the louver 21 and the louver 22 are disposed substantially horizontally. Thereby, an airflow (cold air) is blown out from the blower outlet 5 in a substantially horizontal direction, and the temperature in the room is lowered.

また、暖房運転及び冷房運転を開始して所定期間が経過すると、空気調和機100は上方吹出し状態(第1送風状態)に設定される。上方吹出し状態では図6に示すように、ルーバー10は水平に対して若干前方を上方に向けて傾斜して配置される。また、ルーバー21及びルーバー22は水平吹出し位置と同じ位置に配置される。これにより、吹出口5から上方に気流が吹き出され、天井壁に到達した気流はコアンダ効果により室内の天井壁を伝って広い範囲に気流が行き届く。これにより、室内の温度を均一に維持することができる。   Moreover, when the heating operation and the cooling operation are started and a predetermined period has elapsed, the air conditioner 100 is set to the upward blowing state (first blowing state). In the upward blowing state, as shown in FIG. 6, the louver 10 is disposed so as to be slightly inclined forward with respect to the horizontal. The louver 21 and the louver 22 are arranged at the same position as the horizontal blowing position. Thereby, an airflow is blown upward from the blower outlet 5, and the airflow reaching the ceiling wall reaches the wide range through the indoor ceiling wall by the Coanda effect. Thereby, indoor temperature can be maintained uniformly.

図5、図6に示すように、水平吹出し状態及び上方吹出し状態ではルーバー21が送風通路7の上壁7aに沿って凹部7b内に配される。この時、ルーバー21の先端21cが送風通路7の上壁7aの前端7eよりも前方に配される。これにより、冷房運転時にルーバー21の下面21bに沿って送出される冷気が筐体2の前壁2bから十分離れ、前壁2b上の結露を防止することができる。   As shown in FIGS. 5 and 6, the louver 21 is arranged in the recess 7 b along the upper wall 7 a of the air passage 7 in the horizontal blowing state and the upward blowing state. At this time, the front end 21 c of the louver 21 is arranged in front of the front end 7 e of the upper wall 7 a of the air passage 7. Thereby, the cold air sent along the lower surface 21b of the louver 21 during the cooling operation is sufficiently separated from the front wall 2b of the housing 2, and condensation on the front wall 2b can be prevented.

また、凹部7b内に配されるルーバー21の下面21bの後端21aが凹部7bの後壁7cに近接し、後壁7cの下端7dと略同じ高さに配される。このため、ルーバー21の下面21bと、送風通路7の凹部7bよりも上流の上壁7aとが略同一平面上に配される。   Further, the rear end 21a of the lower surface 21b of the louver 21 disposed in the recess 7b is close to the rear wall 7c of the recess 7b and is disposed at substantially the same height as the lower end 7d of the rear wall 7c. For this reason, the lower surface 21 b of the louver 21 and the upper wall 7 a upstream of the recess 7 b of the air passage 7 are arranged on substantially the same plane.

これにより、送風通路7の上壁7aに沿って配されるルーバー21による段差の形成が防止される。したがって、段差による乱流の発生を防止し、送風効率を向上するとともに騒音を低減することができる。   Thereby, formation of the level | step difference by the louver 21 distribute | arranged along the upper wall 7a of the ventilation path 7 is prevented. Therefore, it is possible to prevent the occurrence of turbulent flow due to a step, improve the air blowing efficiency, and reduce noise.

本実施形態によると、水平吹出し状態(第1送風状態)及び上方吹出し状態(第1送風状態)の時にルーバー21(第2ルーバー)が送風通路7の上壁7aに沿って配置され、ルーバー21の先端21cが送風通路7の上壁7aの前端7eよりも前方に配される。これにより、冷房運転時に冷気がルーバー21に沿って送出され、筐体2の前壁2bに沿った冷気の流通が抑制される。これにより、筐体2上の結露の発生を防止することができる。   According to the present embodiment, the louver 21 (second louver) is arranged along the upper wall 7a of the air passage 7 in the horizontal blowing state (first blowing state) and the upper blowing state (first blowing state). The front end 21c is arranged in front of the front end 7e of the upper wall 7a of the air passage 7. Thereby, the cold air is sent out along the louver 21 during the cooling operation, and the circulation of the cold air along the front wall 2b of the housing 2 is suppressed. Thereby, generation | occurrence | production of the dew condensation on the housing | casing 2 can be prevented.

また、水平吹出し状態及び上方吹出し状態の時に凹部7b内に配されるルーバー21の下面21bの後端21aと凹部7bの後壁7cの下端7dとが略同じ高さに配される。これにより、ルーバー21による段差の形成を防止して乱流の発生を防止し、送風効率を向上するとともに騒音を低減することができる。   In addition, the rear end 21a of the lower surface 21b of the louver 21 and the lower end 7d of the rear wall 7c of the concave portion 7b are arranged at substantially the same height in the horizontal blowing state and the upward blowing state. Thereby, formation of the level | step difference by the louver 21 is prevented, generation | occurrence | production of a turbulent flow is prevented, ventilation efficiency can be improved, and noise can be reduced.

また、水平吹出し状態及び上方吹出し状態にルーバー21の下面21bと送風通路7の凹部7bよりも上流の上壁7aとが略同一平面上に配される。これにより、ルーバー21による段差の形成を容易に防止することができる。   Further, the lower wall 21b of the louver 21 and the upper wall 7a upstream of the recess 7b of the air passage 7 are arranged on substantially the same plane in the horizontal blowing state and the upward blowing state. Thereby, formation of the level | step difference by the louver 21 can be prevented easily.

本実施形態において、上方吹出し状態を省いてもよい。また、水平吹出し状態を省き、上方吹出し状態で冷房運転を行ってもよい。   In the present embodiment, the upward blowing state may be omitted. Alternatively, the horizontal blowing state may be omitted and the cooling operation may be performed in the upward blowing state.

また、凹部7bの後壁7cを送風通路7の凹部7bよりも上流の上壁7aに連続した傾斜面により形成し、該傾斜面に沿ってルーバー21の上面を形成してもよい。これにより、下方吹出し状態の時に凹部7bの後壁7cにより形成される段差による乱流の発生を抑制することができる。   Alternatively, the rear wall 7c of the recess 7b may be formed by an inclined surface that is continuous with the upper wall 7a upstream of the recess 7b of the air passage 7, and the upper surface of the louver 21 may be formed along the inclined surface. Thereby, generation | occurrence | production of the turbulent flow by the level | step difference formed of the rear wall 7c of the recessed part 7b at the time of a downward blowing state can be suppressed.

Thereby, the formation of a step by the rear wall 7c of the recess 7b can be prevented to prevent the generation of turbulent flow, and the blowing efficiency can be improved and the noise can be reduced.

また、可動板16が水平吹出し状態及び上方吹出し状態の時にルーバー21により押し上げられ、下方吹出し状態の時に自重により降下する。これにより、ルーバー21の昇降動作を容易に実現できる。   Further, the movable plate 16 is pushed up by the louver 21 when the movable plate 16 is in the horizontal blowing state and the upper blowing state, and descends by its own weight when the movable plate 16 is in the lower blowing state. Thereby, the raising / lowering operation | movement of the louver 21 is easily realizable.

本実施形態において、可動板16を下方に付勢するバネ等の付勢部(不図示)を可動板16の上面16aに設けてもよい。これにより、下方吹出し状態の時に送風通路7内を流通する気流による可動板16の浮き上がりを防止することができる。   In the present embodiment, an urging portion (not shown) such as a spring that urges the movable plate 16 downward may be provided on the upper surface 16 a of the movable plate 16. Thereby, it is possible to prevent the movable plate 16 from being lifted by the airflow flowing through the air passage 7 when in the downward blowing state.

<第3実施形態>
次に、図9は第3実施形態の空気調和機100の室内機1の吹出口5近傍の側面断面図を示している。説明の便宜上、前述の図1〜図6に示す第1実施形態と同様の部分には同一の符号を付している。本実施形態はルーバー21の下面21bに突起部15が設けられる。その他の部分は第1実施形態と同様である。
<Third Embodiment>
Next, FIG. 9 shows a side sectional view of the vicinity of the air outlet 5 of the indoor unit 1 of the air conditioner 100 of the third embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the protrusion 15 is provided on the lower surface 21 b of the louver 21. Other parts are the same as those in the first embodiment.

突起部15はルーバー21の下面21bに突設され、ルーバー21の両側端部に設けられる。   The protrusions 15 protrude from the lower surface 21 b of the louver 21 and are provided at both end portions of the louver 21.

送風停止時にルーバー10及びルーバー21は同図に示す原点位置に配置される。原点位置ではルーバー21が送風通路7の上壁7aに沿って凹部7b内に配され、ルーバー10が突起部15に当接して吹出口5を閉じる。吹出口5の風向を可変する際にルーバー10及びルーバー21は原点位置に復帰した後に所定位置に配される。   The louver 10 and the louver 21 are arranged at the origin position shown in FIG. At the origin position, the louver 21 is arranged in the recess 7 b along the upper wall 7 a of the air passage 7, and the louver 10 abuts against the protrusion 15 to close the outlet 5. When changing the air direction of the air outlet 5, the louver 10 and the louver 21 are arranged at predetermined positions after returning to the original position.

ルーバー10及びルーバー21は経年変化により変形する場合がある。この時、ルーバー10及びルーバー21は原点位置に復帰する際に互いに押圧されて変形が矯正される。しかし、ルーバー10とルーバー21との当接位置が変動すると、当接位置によって両者が所望の形状に矯正されずに原点位置が変動する可能性がある。   The louver 10 and the louver 21 may be deformed due to aging. At this time, when the louver 10 and the louver 21 return to the original position, they are pressed against each other to correct the deformation. However, when the contact position between the louver 10 and the louver 21 varies, there is a possibility that the origin position may vary without being corrected to a desired shape depending on the contact position.

このため、ルーバー21の両側端部に突起部15に設けることにより、ルーバー10の当接位置の変動を防止することができる。これにより、ルーバー10及びルーバー21が経年変化により変形しても所定の原点位置に安定して配置される。   For this reason, by providing the protrusions 15 at both end portions of the louver 21, fluctuations in the contact position of the louver 10 can be prevented. Thereby, even if the louver 10 and the louver 21 are deformed due to aging, they are stably arranged at a predetermined origin position.

本実施形態によると、第1実施形態と同様の効果を奏することができる。また、ルーバー21(第2ルーバー)の両側端部に突起部15を設けたので、ルーバー10及びルーバー21を原点位置に安定して配置することができる。   According to this embodiment, the same effects as those of the first embodiment can be obtained. In addition, since the protrusions 15 are provided at both end portions of the louver 21 (second louver), the louver 10 and the louver 21 can be stably arranged at the origin position.

なお、本実施形態に第2実施形態を組み合わせた構成でもよい。   In addition, the structure which combined 2nd Embodiment with this embodiment may be sufficient.

Further, some or all of the embodiments of the present invention may be used in combination.

例えば、ルーバー10は矩形状の平板で形成されるが、円弧状や婉曲状の平板であってもよい。また、平板状の平板部と婉曲状の婉曲部とを有する構造(上面は平板部で下面が婉曲部、上面が婉曲部で下面が婉曲部など)であってもよい。   For example, the louver 10 is formed of a rectangular flat plate, but may be an arcuate or curved flat plate. Further, a structure having a flat plate portion and a bent portion (a top surface is a flat plate portion, a lower surface is a bent portion, an upper surface is a bent portion, and a lower surface is a bent portion) may be used.

また、ルーバー21平板状に形成されているが、第1送風状態において、凹部7bに収まる形状であればよい。例えば、ルーバー21の下面が平板部で、上面が婉曲部を有する形状であってもよい。   Moreover, although it is formed in the flat shape of the louver 21, it may be a shape that can be accommodated in the concave portion 7b in the first blowing state. For example, the lower surface of the louver 21 may be a flat plate portion and the upper surface may have a curved portion.
