しかしながら、このものの場合、例えば、冷房時に気流の方向を水平方向にするために、上下羽根を水平方向に傾けると、気流が上下羽根を通過するときに、上下羽根の下面を通過する気流の一部が水平方向に偏向されず空気密度の違いにより下方向に流れてしまう。
また、暖房時に気流の方向を下方向にするために、上下羽根を下方向に傾けると、気流が上下羽根を通過するときに、上下羽根の上面を通過する気流の一部が下方向に偏向されず上方向に流れてしまう。その結果、気流の制御性が低下してしまうという問題点があった。 However, in this case, for example, when the upper and lower blades are tilted in the horizontal direction in order to make the direction of the air flow horizontal during cooling, when the air flow passes through the upper and lower blades, The part is not deflected in the horizontal direction and flows downward due to the difference in air density.
In addition, if the upper and lower blades are tilted downward to make the airflow direction downward during heating, when the airflow passes through the upper and lower blades, a part of the airflow passing through the upper and lower blades is deflected downward. Instead, it flows upward. As a result, there is a problem that the controllability of the airflow is lowered.

次に、実施の形態１に係る空気調和機の動作について説明する。
まず、冷房時に吹出し口２から気流を水平方向に吹出す場合について説明する。なお、空気調和機は、冷房時以外であっても気流を水平方向に吹出す場合があるので、冷房時に限定するものではない。
図示しない制御部からの駆動信号に基づいて、モータ１１を駆動させることにより、上下羽根回転軸７ａが一方向に回動して、上下羽根７は上下羽根回転軸７ａを中心に回動して水平方向に向けられる。
ファン５の回転により吸込み口１から空気が吸い込まれ、この吸い込まれた空気が熱交換器６を通過する。熱交換器６の温度は、所定の温度に制御されているので、熱交換器６を通過した空気の温度は、設定温度（冷房温度）となる。熱交換器６を通過した空気は、ファン５により風向偏向手段８へ運ばれる。 Next, the operation of the air conditioner according to Embodiment 1 will be described.
First, the case where an air flow is blown out horizontally from the blow-out port 2 during cooling will be described. The air conditioner is not limited to cooling because airflow may be blown in the horizontal direction even at times other than cooling.
By driving the motor 11 based on a drive signal from a control unit (not shown), the upper and lower blade rotation shaft 7a rotates in one direction, and the upper and lower blades 7 rotate about the upper and lower blade rotation shaft 7a. Directed horizontally.
As the fan 5 rotates, air is sucked from the suction port 1, and the sucked air passes through the heat exchanger 6. Since the temperature of the heat exchanger 6 is controlled to a predetermined temperature, the temperature of the air that has passed through the heat exchanger 6 becomes a set temperature (cooling temperature). The air that has passed through the heat exchanger 6 is carried by the fan 5 to the wind direction deflecting means 8.

上下羽根回転軸７ａが一方向に回動すると、図４に示すように、間欠カム１２が同期して矢印Ｂの方向に回動し、第１の溝１２ａ、第２の溝１２ｂおよび第３の溝１２ｃが回動する。
第１の溝１２ａ、第２の溝１２ｂおよび第３の溝１２ｃが矢印Ｂの方向に回動することで、図４に示すように、下面従動接触子１４は、第１の溝１２ａに沿って摺動し、上面従動接触子１３は、第２の溝１２ｂに沿って摺動する。
その結果、下面風向偏向板１０の先端部が上下羽根７の下面に指向し、上面風向偏向板９は風路３の上壁の形状に合うように傾き、上下羽根７の上面に沿った気流には影響を与えない。 When the upper and lower blade rotation shaft 7a rotates in one direction, as shown in FIG. 4, the intermittent cam 12 rotates synchronously in the direction of arrow B, and the first groove 12a, the second groove 12b, and the third groove The groove 12c rotates.
As the first groove 12a, the second groove 12b, and the third groove 12c rotate in the direction of arrow B, as shown in FIG. 4, the lower surface driven contactor 14 extends along the first groove 12a. The upper surface driven contact 13 slides along the second groove 12b.
As a result, the front end portion of the lower surface wind direction deflecting plate 10 is directed toward the lower surface of the upper and lower blades 7, the upper surface wind direction deflecting plate 9 is tilted so as to match the shape of the upper wall of the air path 3, and the air flow along the upper surface of the upper and lower blades 7. Has no effect.

ファン５から下面風向偏向板１０に運ばれた気流は、下面風向偏向板１０の上面に衝突して、上下羽根７の下面方向に偏向される。
このとき、上下羽根７と下面風向偏向板１０との間の流路断面積が小さくなるので、気流が縮流して、気流の速度が増加する。
上下羽根７は、断面円弧形状であるので、気流は上下羽根７の下面に沿って流れ、上下羽根７の先端部は水平方向を向いているので、吹出し口２付近での気流は、水平方向に偏向される。
このように、上下羽根７を用いて気流を水平方向に偏向する際に、下面風向偏向板１０により、気流が上下羽根７の下面から下方向に吹き抜けることを抑制し、さらに、気流の縮流によって風速を増加させることができるので、十分な量の気流を遠くまで送ることができる。 The airflow carried from the fan 5 to the lower surface wind direction deflecting plate 10 collides with the upper surface of the lower surface wind direction deflecting plate 10 and is deflected toward the lower surface of the upper and lower blades 7.
At this time, since the cross-sectional area of the flow path between the upper and lower blades 7 and the lower surface wind direction deflecting plate 10 becomes small, the air flow contracts and the speed of the air flow increases.
Since the upper and lower blades 7 have an arc shape in cross section, the airflow flows along the lower surface of the upper and lower blades 7 and the tip portion of the upper and lower blades 7 faces the horizontal direction. To be biased.
Thus, when the airflow is deflected in the horizontal direction using the upper and lower blades 7, the lower surface wind direction deflecting plate 10 suppresses the airflow from being blown downward from the lower surface of the upper and lower blades 7, and further the contraction of the airflow Since the wind speed can be increased, a sufficient amount of airflow can be sent far.

次に、冷房状態から暖房状態に移行させ、吹出し口２の気流の方向を水平方向から下方向へ切換える場合の空気調和機の動作について説明する。なお、空気調和機は、暖房時以外であっても気流を下方向に吹出す場合があるので、暖房時に限定するものではない。
図５は上下羽根７が水平方向から下方向側に傾いたときの吹出し口２付近の断面図であり、図６は図５の間欠カム１２と上面従動接触子１３と下面従動接触子１４との関係を示した図である。
制御部からの駆動信号に基づき、モータ１１が駆動して、上下羽根回転軸７ａが他方向に回動して、上下羽根７が上下羽根回転軸７ａを中心にして下方向に向かって回動する。
間欠カム１２が、上下羽根回転軸７ａとともに、図６の矢印Ｃの方向に回動することにより、図５に示すように、上下羽根７は上下羽根回転軸７ａの回動角度と同じ角度だけ回動し、下方向側に傾く。
上面従動接触子１３は、第２の溝１２ｂに沿って摺動するので、上面風向偏向手段回転軸９ａは回動せず、上面風向偏向板９は回動しない。
一方、下面従動接触子１４は、第３の溝１２ｃに沿って摺動して、第２の溝１２ｂに到達する。
このとき、下面風向偏向手段回転軸１０ａを中心に下面従動接触子１４がθ１度だけ図６の矢印Ｄの方向に回動する。下面風向偏向板１０は下面従動接触子１４とともにθ１度だけ回動し、下面風向偏向板１０は、風路３の下壁の形状に合うように傾き、上下羽根７の下面に沿った気流には影響を与えない。 Next, the operation of the air conditioner in the case of switching from the cooling state to the heating state and switching the direction of the airflow at the outlet 2 from the horizontal direction to the downward direction will be described. In addition, since an air conditioner may blow off an airflow even if it is except the time of heating, it is not limited to the time of heating.
FIG. 5 is a cross-sectional view of the vicinity of the air outlet 2 when the upper and lower blades 7 are tilted downward from the horizontal direction. FIG. 6 shows the intermittent cam 12, the upper surface driven contact 13 and the lower surface driven contact 14 of FIG. FIG.
Based on the drive signal from the control unit, the motor 11 is driven, the upper and lower blade rotation shaft 7a rotates in the other direction, and the upper and lower blades 7 rotate downward about the upper and lower blade rotation shaft 7a. To do.
As the intermittent cam 12 rotates together with the upper and lower blade rotation shafts 7a in the direction of the arrow C in FIG. 6, as shown in FIG. 5, the upper and lower blades 7 have the same angle as the rotation angle of the upper and lower blade rotation shafts 7a. Rotates and tilts downward.
Since the upper surface driven contact 13 slides along the second groove 12b, the upper surface wind direction deflecting means rotating shaft 9a does not rotate, and the upper surface wind direction deflecting plate 9 does not rotate.
On the other hand, the lower surface driven contact 14 slides along the third groove 12c and reaches the second groove 12b.
At this time, the lower surface driven contact 14 rotates in the direction of arrow D in FIG. 6 by θ1 degree around the lower surface wind direction deflecting means rotating shaft 10a. The lower surface wind direction deflecting plate 10 rotates together with the lower surface driven contact 14 by θ1 degree, and the lower surface wind direction deflecting plate 10 is tilted so as to match the shape of the lower wall of the air path 3 and flows along the lower surface of the upper and lower blades 7. Has no effect.

さらに、モータ１１が駆動して、上下羽根回転軸７ａとともに間欠カム１２を図６の矢印Ｃの方向に回動させると、上下羽根７は上下羽根回転軸７ａの回動角度と同じ角度だけ回動し、さらに下方向側に傾く。
上面従動接触子１３は、第２の溝１２ｂに沿って摺動するので、上面風向偏向手段回転軸９ａは回動せず、上面風向偏向板９は回動しない。
また、下面従動接触子１４も、第２の溝１２ｂに沿って摺動するので、下面風向偏向手段回転軸１０ａは回動せず、下面風向偏向板１０も回動しない。 Further, when the motor 11 is driven to rotate the intermittent cam 12 together with the upper and lower blade rotation shaft 7a in the direction of arrow C in FIG. 6, the upper and lower blades 7 rotate by the same angle as the rotation angle of the upper and lower blade rotation shaft 7a. It moves and tilts further downward.
Since the upper surface driven contact 13 slides along the second groove 12b, the upper surface wind direction deflecting means rotating shaft 9a does not rotate, and the upper surface wind direction deflecting plate 9 does not rotate.
Further, since the lower surface driven contact 14 also slides along the second groove 12b, the lower surface wind direction deflecting means rotating shaft 10a does not rotate, and the lower surface wind direction deflecting plate 10 does not rotate.

さらに、モータ１１を駆動させることにより、上下羽根回転軸７ａが他方向に回動して、上下羽根７は上下羽根回転軸７ａを中心に回動して下方向に向けられる。
図７は上下羽根７が下方向を向いているときの吹出し口２付近の断面図、図８は図７の間欠カム１２と上面従動接触子１３と下面従動接触子１４との関係を示す図である。
上下羽根回転軸７ａが他方向にさらに回動すると、間欠カム１２が同期して回動する。
下面従動接触子１４は、第２の溝１２ｂに沿って摺動するので、下面風向偏向手段回転軸１０ａは回動せず、下面風向偏向板１０は回動しない。
その結果、下面風向偏向板１０は、上下羽根７の下面に沿った気流には影響を与えないままである。
一方、上面従動接触子１３は、第３の溝１２ｃに沿って摺動して、第１の溝１２ａに到達する。
図８に示すように、上面風向偏向手段回転軸９ａを中心に上面従動接触子１３がθ２度だけ矢印Ｅの方向に回動する。上面風向偏向板９は上面従動接触子１３とともにθ２度だけ回動し、上面風向偏向板９の先端部が上下羽根７の上面に指向する。 Further, by driving the motor 11, the upper and lower blade rotation shaft 7a rotates in the other direction, and the upper and lower blades 7 rotate about the upper and lower blade rotation shaft 7a and are directed downward.
7 is a cross-sectional view of the vicinity of the air outlet 2 when the upper and lower blades 7 are directed downward, and FIG. 8 is a diagram showing the relationship among the intermittent cam 12, the upper surface driven contact 13 and the lower surface driven contact 14 of FIG. It is.
When the upper and lower blade rotation shaft 7a is further rotated in the other direction, the intermittent cam 12 is rotated in synchronization.
Since the lower surface driven contact 14 slides along the second groove 12b, the lower surface wind direction deflecting means rotating shaft 10a does not rotate, and the lower surface wind direction deflecting plate 10 does not rotate.
As a result, the lower surface wind direction deflecting plate 10 remains unaffected by the airflow along the lower surfaces of the upper and lower blades 7.
On the other hand, the upper surface driven contact 13 slides along the third groove 12c and reaches the first groove 12a.
As shown in FIG. 8, the upper surface driven contact 13 rotates in the direction of the arrow E by θ2 degrees around the upper surface wind direction deflecting means rotating shaft 9a. The upper surface wind direction deflecting plate 9 rotates together with the upper surface follower contact 13 by θ2 degrees, and the front end portion of the upper surface wind direction deflecting plate 9 is directed to the upper surfaces of the upper and lower blades 7.

ファン５から上面風向偏向板９に運ばれた気流は、図７に示すように、上面風向偏向板９の下面に衝突して、矢印Ｆの方向である上下羽根７の上面方向に偏向される。
上下羽根７と上面風向偏向板９との間の流路断面積が小さくなるので、気流が縮流して、気流の速度が増大する。
このように、上下羽根７を用いて気流を下方向に偏向する際に、上面風向偏向板９により、気流が上下羽根７の上面から水平方向に吹き抜けることを抑制し、さらに、気流の縮流によって風速を増加させることができるので、吹出し口２付近での気流は、下方向である矢印Ｇの方向に偏向され、狭い吹出し幅で、速度が増大して吹出される。 As shown in FIG. 7, the airflow carried from the fan 5 to the upper surface wind direction deflecting plate 9 collides with the lower surface of the upper surface wind direction deflecting plate 9 and is deflected in the upper surface direction of the upper and lower blades 7 as indicated by the arrow F. .
Since the cross-sectional area of the flow path between the upper and lower blades 7 and the upper surface wind direction deflecting plate 9 is reduced, the airflow is contracted and the speed of the airflow is increased.
In this way, when the airflow is deflected downward using the upper and lower blades 7, the upper surface wind direction deflecting plate 9 prevents the airflow from being blown from the upper surface of the upper and lower blades 7 in the horizontal direction, and further the contraction of the airflow Therefore, the air velocity in the vicinity of the air outlet 2 is deflected in the direction of the arrow G, which is the lower direction, and is blown out with a narrow air width and an increased speed.

図９（ａ）は、下面風向偏向板１０の配置される位置と回動角度との関係を示す図であり、図９（ｂ）は、上面風向偏向板９の配置される位置と回動角度との関係を示す図である。
上面風向偏向板９の配置される位置は、風路３の上壁であればどこでもよく、また、下面風向偏向板１０の配置される位置は、風路３の下壁あればどこでもよいが、より優れた効果を得るためには、上面風向偏向板９および下面風向偏向板１０の配置位置、寸法および回動角度が、上下羽根７との位置、寸法および回動角度に制約される。
下面風向偏向板１０は、気流を上下羽根７の下面に当てる必要があるため、上下羽根７および下面風向偏向板１０を回動させたときに、下面風向偏向板１０の延長線１５が上下羽根７の上流側端部より下流側になるように、下面風向偏向板１０の配置される位置および回動角度を決定する。
また、上面風向偏向板９は、気流を上下羽根７の上面に当てる必要があるため、上下羽根７および上面風向偏向板９を回動させたときに、上面風向偏向板９の延長線１６が上下羽根７の上流側端部より下流側になるように、上面風向偏向板９の配置される位置および回動角度を決定する。 FIG. 9A is a diagram showing the relationship between the position at which the lower surface wind direction deflecting plate 10 is disposed and the rotation angle, and FIG. 9B is the position at which the upper surface wind direction deflecting plate 9 is disposed and the rotation. It is a figure which shows the relationship with an angle.
The position where the upper surface wind direction deflecting plate 9 is disposed may be anywhere as long as it is the upper wall of the air path 3, and the position where the lower surface wind direction deflecting plate 10 is disposed may be anywhere as long as it is the lower wall of the air path 3. In order to obtain a more excellent effect, the arrangement position, size, and rotation angle of the upper surface wind direction deflecting plate 9 and the lower surface wind direction deflecting plate 10 are restricted by the position, size, and rotation angle with respect to the upper and lower blades 7.
Since the lower surface wind direction deflecting plate 10 needs to apply an air flow to the lower surfaces of the upper and lower blades 7, when the upper and lower blades 7 and the lower surface wind direction deflecting plate 10 are rotated, the extension line 15 of the lower surface wind direction deflecting plate 10 becomes the upper and lower blades. The position and rotation angle of the lower surface wind direction deflecting plate 10 are determined so as to be on the downstream side of the upstream end of 7.
Further, since the upper surface wind direction deflecting plate 9 needs to apply an air flow to the upper surfaces of the upper and lower blades 7, when the upper and lower blades 7 and the upper surface wind direction deflecting plate 9 are rotated, the extension line 16 of the upper surface wind direction deflecting plate 9 is The position and rotation angle of the upper surface wind direction deflecting plate 9 are determined so as to be downstream from the upstream end of the upper and lower blades 7.

実施の形態１に係る空気調和機によると、ファン５と上下羽根７との間には、風路３内の気流を上下羽根７に向かって偏向させる風向偏向手段８が設けられているので、風路３内の気流が上下羽根７によって制御されやすくなり、吹出し口２から吹出される気流の制御性を向上させることができる。
また、上下羽根７および風向偏向手段８とモータ１１との間に回動力伝達機構１７を設けることで、簡単に上下羽根７および風向偏向手段８を回動させることができる。 According to the air conditioner according to Embodiment 1, air direction deflecting means 8 is provided between the fan 5 and the upper and lower blades 7 to deflect the airflow in the air passage 3 toward the upper and lower blades 7. The airflow in the air passage 3 is easily controlled by the upper and lower blades 7, and the controllability of the airflow blown from the blowout port 2 can be improved.
Further, by providing the rotational power transmission mechanism 17 between the upper and lower blades 7 and the wind direction deflecting means 8 and the motor 11, the upper and lower blades 7 and the wind direction deflecting means 8 can be easily rotated.

また、間欠カム１２には、上面従動接触子１３および下面従動接触子１４が摺動する第１の溝１２ａ、第２の溝１２ｂおよび第３の溝１２ｃが形成されているので、簡単な構成で、上面風向偏向板９および下面風向偏向板１０を回動させることができる。   Further, the intermittent cam 12 is formed with a first groove 12a, a second groove 12b, and a third groove 12c in which the upper surface driven contact 13 and the lower surface driven contact 14 slide. Thus, the upper surface wind direction deflecting plate 9 and the lower surface wind direction deflecting plate 10 can be rotated.

また、風向偏向手段８は上面風向偏向板９および下面風向偏向板１０を有しているので、気流の方向を上下羽根７の上面および下面の両方に偏向させることができる。   Further, since the wind direction deflecting means 8 includes the upper surface wind direction deflecting plate 9 and the lower surface wind direction deflecting plate 10, the direction of the airflow can be deflected to both the upper surface and the lower surface of the upper and lower blades 7.

また、気流を偏向させるために、上下羽根７を吹出し口２の外側にせり出させる必要がないので、例えば、冷房時において、熱交換器６を通過して冷却された気流により冷却された上下羽根７が、温度の高い室内空気に触れにくくなり、上下羽根７に結露が発生することを抑制することができる。   Further, since it is not necessary to project the upper and lower blades 7 to the outside of the air outlet 2 in order to deflect the airflow, for example, during cooling, the upper and lower blades cooled by the airflow cooled by passing through the heat exchanger 6 are used. It becomes difficult for the blades 7 to come into contact with high-temperature indoor air, and the occurrence of condensation on the upper and lower blades 7 can be suppressed.
