Description

この発明は、吹出し口に設けられ、ファンにより発生する気流の方向を上下方向に偏向させる上下羽根を備えた空気調和機に関する。   The present invention relates to an air conditioner provided with upper and lower blades that are provided at an outlet and deflect the direction of airflow generated by a fan in the vertical direction.

従来、吸込み口と吹出し口とを連通した風路が形成されたケースと、前記風路内に設けられ、気流を発生させるファンと、前記吹出し口に設けられ、前記気流の方向を上下方向に偏向させる上下羽根とを備えた空気調和機が知られている（例えば、特許文献１参照）。
空気温度の差による空気密度の違いによって、冷却された気流を送り出す冷房時には空気調和機から吹出される気流は下方向に流れ、加熱された気流を送り出す暖房時には空気調和機から吹出される気流は上方向に流れるので、冷房時には気流を水平方向に制御し、暖房時には気流を下方向に制御して、部屋の中における温度のむらを低減する。 Conventionally, a case in which an air passage is formed in which an air inlet and an air outlet are communicated, a fan that is provided in the air passage and generates an air flow, and is provided in the air outlet, and the direction of the air flow is set in the vertical direction. There is known an air conditioner including upper and lower blades to be deflected (see, for example, Patent Document 1).
Due to the difference in air density due to the difference in air temperature, the airflow blown out from the air conditioner flows downward during cooling to send out the cooled airflow, and the airflow blown out from the air conditioner during heating to send out the heated airflow is Since it flows upward, the air flow is controlled horizontally during cooling, and the air flow is controlled downward during heating to reduce temperature unevenness in the room.

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.

この発明は、上述のような問題点を解決することを課題とするものであって、その目的は、気流の制御性を向上させることができる空気調和機を提供するものである。   This invention makes it a subject to solve the above problems, The objective is to provide the air conditioner which can improve controllability of an airflow.

この発明に係る空気調和機は、吸込み口と吹出し口とを連通した風路が形成されたケースと、前記風路内に設けられ、気流を発生させるファンと、前記吹出し口に設けられ、前記吹出し口から吹出される前記気流の方向を上下方向に偏向させる上下羽根と、前記ファンと前記上下羽根との間に設けられ、前記風路内の前記気流の方向を前記上下羽根側に向かって偏向させる風向偏向手段とを備えている。   An air conditioner according to the present invention is provided in a case in which an air passage that communicates an inlet and an outlet is formed, a fan that is provided in the air passage and generates an air current, and is provided in the outlet. Provided between the upper and lower blades for deflecting the direction of the airflow blown from the outlet in the vertical direction, the fan and the upper and lower blades, and the direction of the airflow in the air passage toward the upper and lower blades Wind direction deflecting means for deflecting.

この発明に係る空気調和機によれば、気流の制御性を向上させることができる。   According to the air conditioner according to the present invention, the controllability of airflow can be improved.

また、この空気調和機は、風路３内に設けられ、気流を発生させるファン５と、吸込み口１とファン５との間に設けられ、吸込み口１から吸い込まれた空気と熱交換を行う熱交換器６と、吹出し口２に設けられ、吹出し口２から吹出される気流の方向を上下方向に偏向させる上下羽根７と、ファン５と上下羽根７との間に設けられ、風路３内の気流の方向を上下羽根７側に向かって偏向させる風向偏向手段８とを備えている。

In this specification, the direction of arrow A in FIG.
Embodiment 1 FIG.
FIG. 1 is a configuration diagram of the air conditioner according to Embodiment 1, and FIG. 2 is a perspective view showing a lower surface wind direction deflecting plate 10 of FIG.
The air conditioner according to Embodiment 1 communicates a suction port 1 that sucks air from the outside, a blowout port 2 that blows air sucked from the suction port 1 to the outside, and a suction port 1 and a blowout port 2. A case 4 in which the air path 3 is formed is provided.
In addition, this air conditioner is provided in the air passage 3 and is provided between the fan 5 that generates an air flow, the suction port 1 and the fan 5, and performs heat exchange with the air sucked from the suction port 1. It is provided between the heat exchanger 6 and the upper and lower blades 7 that are provided in the blowout port 2 and deflect the direction of the airflow blown from the blowout port 2 in the vertical direction, and between the fan 5 and the upper and lower blades 7. Wind direction deflecting means 8 for deflecting the direction of the air flow toward the upper and lower blades 7 is provided.
The upper and lower blades 7 are rotatable around a rotation shaft 7 a extending toward both side walls of the air passage 3.

風向偏向手段８は、風路３の内壁のうち、上壁に設けられた上面風向偏向板９と、風路３の下壁に設けられた下面風向偏向板１０とを有している。
上面風向偏向板９および下面風向偏向板１０は、風路３内の気流を上下羽根７側に向かって偏向させる偏向板である円弧板が用いられている。上面風向偏向板９および下面風向偏向板１０は、風路３の壁側に沿うように傾けると気流の流動抵抗を増大させないように、風路３の壁の形状に合わせて形成されている。なお、偏向板は、円弧板に限らず、例えば、平板であってもよい。
上面風向偏向板９は、基部が風路３の上壁に回転軸９ａを介して回動可能に取付けられ、先端部が上下羽根７の上面に指向するようになっている。
下面風向偏向板１０は、基部が風路３の下壁に回転軸１０ａを介して回動可能に取付けられ、先端部が上下羽根７の下面に指向するようになっている。
上面風向偏向板９、回転軸９ａ、下面風向偏向板１０および回転軸１０ａは、樹脂で形成されている。
上面風向偏向板９および下面風向偏向板１０の回動は、図示しない、制御部、モータおよびリンク機構によって行われる。 The wind direction deflecting means 8 has an upper surface wind direction deflecting plate 9 provided on the upper wall of the inner wall of the air path 3 and a lower surface wind direction deflecting plate 10 provided on the lower wall of the air path 3.
The upper surface wind direction deflecting plate 9 and the lower surface wind direction deflecting plate 10 are arc plates that are deflecting plates that deflect the airflow in the air path 3 toward the upper and lower blades 7. The upper surface wind direction deflecting plate 9 and the lower surface wind direction deflecting plate 10 are formed in accordance with the shape of the wall of the air path 3 so as not to increase the flow resistance of the air flow when tilted along the wall side of the air path 3. The deflecting plate is not limited to the arc plate, and may be a flat plate, for example.
The upper surface wind direction deflecting plate 9 has a base portion rotatably attached to the upper wall of the air passage 3 via a rotation shaft 9 a, and a distal end portion is directed to the upper surfaces of the upper and lower blades 7.
The lower surface wind direction deflecting plate 10 has a base portion rotatably attached to the lower wall of the air passage 3 via a rotation shaft 10 a, and a distal end portion is directed to the lower surface of the upper and lower blades 7.
Upper surface wind direction deflecting plate 9, rotating shaft 9a, lower surface wind direction deflecting plate 10 and rotating shaft 10a are made of resin.
The upper wind direction deflecting plate 9 and the lower surface wind direction deflecting plate 10 are rotated by a control unit, a motor, and a link mechanism (not shown).

図３（ａ）は下面風向偏向板１０が配置される位置と下面風向偏向板１０の回動角度との関係を示す説明図、図３（ｂ）は上面風向偏向板９が配置される位置と上面風向偏向板９の回動角度との関係を示す説明図である。
風路３内における下面風向偏向板１０および上面風向偏向板９の位置、寸法および回動角度は、風向偏向手段８による有効な効果を得るために、上下羽根７の位置、寸法および回動角度が制約される。 3A is an explanatory diagram showing the relationship between the position where the lower surface wind direction deflecting plate 10 is disposed and the rotation angle of the lower surface wind direction deflecting plate 10, and FIG. 3B is the position where the upper surface wind direction deflecting plate 9 is disposed. It is explanatory drawing which shows the relationship between the angle of rotation and the rotation angle of the upper surface wind direction deflection | deviation plate 9. FIG.
The position, size and rotation angle of the lower surface wind direction deflecting plate 10 and the upper surface wind direction deflecting plate 9 in the air path 3 are the position, size and rotation angle of the upper and lower blades 7 in order to obtain an effective effect by the wind direction deflecting means 8. Is constrained.

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、回動時には、下面風向偏向板１０の延長線上に上下羽根７の下面があるように、下面風向偏向板１０の位置、寸法および回動角度を決定する。
同様にして、上面風向偏向板９も、気流を上下羽根７の上面に当てる必要があるため、回動時には、上面風向偏向板９の延長線上に上下羽根７の上面があるように、上面風向偏向板９の位置、寸法および回動角度を決定する。 Since the lower surface wind direction deflecting plate 10 needs to apply an air flow to the lower surface of the upper and lower blades 7, when rotating, the lower surface wind direction deflecting plate 10 has the lower surface of the upper and lower blades 7 on the extension line of the lower surface wind direction deflecting plate 10. Determine position, dimensions and rotation angle.
Similarly, the upper surface wind direction deflecting plate 9 also needs to apply an air flow to the upper surfaces of the upper and lower blades 7, and therefore, when rotating, the upper surface wind direction so that the upper surfaces of the upper and lower blades 7 are on the extension line of the upper surface wind direction deflecting plate 9. The position, size and rotation angle of the deflection plate 9 are determined.

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４は図１の空気調和機の吹出し口２から気流を水平方向に吹出したときの吹出し口２付近を示した説明図である。
上下羽根７は、回転軸７ａを中心に回動され、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。
回転軸１０ａを中心に下面風向偏向板１０を回動させて、下面風向偏向板１０の先端部を上下羽根７の下面に指向させる。なお、上面風向偏向板９は風路３の上壁の形状に合うように回動させて、上下羽根７の上面に沿った気流には影響を与えないようになっている。 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.
FIG. 4 is an explanatory view showing the vicinity of the air outlet 2 when the air flow is blown out horizontally from the air outlet 2 of the air conditioner of FIG.
The upper and lower blades 7 are rotated about the rotation shaft 7a and directed in the horizontal direction.
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.
The lower surface wind direction deflecting plate 10 is rotated about the rotation shaft 10 a so that the tip of the lower surface wind direction deflecting plate 10 is directed to the lower surface of the upper and lower blades 7. The upper surface wind direction deflecting plate 9 is rotated so as to match the shape of the upper wall of the air passage 3 so that the airflow along the upper surface of the upper and lower blades 7 is not affected.

図５は、図４の上下羽根７および下面風向偏向板１０により水平方向に偏向される気流を示した説明図である。
ファン５により発生した気流１１ａは、風路３の形状に合った方向を向いており、下面風向偏向板１０の上面に衝突して偏向される。下面風向偏向板１０の上面と衝突した気流１１ｂは、上下羽根７に向かった方向となる。上下羽根７に向かって偏向された気流１１ｂは、上下羽根７の下面に衝突して再び偏向される。上下羽根７の下面に衝突した気流１１ｃは、風路３の下壁と上下羽根７との間の幅Ｈに対して、上下羽根７の下面からＨより短い幅ｈの間を通過する。つまり、気流１１ｃの幅ｈは、風路３の下壁と上下羽根７との間の幅Ｈと比較して、ｈ／Ｈの割合だけ狭くなるので、気流が縮流し、気流の速度が増加する。
上下羽根７の下面は、円弧状になっており、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１１ｄ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。 FIG. 5 is an explanatory diagram showing the airflow deflected in the horizontal direction by the upper and lower blades 7 and the lower surface wind direction deflecting plate 10 of FIG.
The air flow 11 a generated by the fan 5 is directed in a direction that matches the shape of the air path 3, and is deflected by colliding with the upper surface of the lower surface wind direction deflecting plate 10. The airflow 11 b that collides with the upper surface of the lower surface wind direction deflecting plate 10 is directed toward the upper and lower blades 7. The airflow 11b deflected toward the upper and lower blades 7 collides with the lower surface of the upper and lower blades 7 and is deflected again. The air flow 11 c that has collided with the lower surface of the upper and lower blades 7 passes through a width h shorter than H from the lower surface of the upper and lower blades 7 with respect to the width H between the lower wall of the air passage 3 and the upper and lower blades 7. That is, the width h of the air flow 11c is narrowed by a ratio of h / H as compared with the width H between the lower wall of the air passage 3 and the upper and lower blades 7, so that the air flow contracts and the speed of the air flow increases. To do.
The lower surfaces of the upper and lower blades 7 have an arc shape, and the tip portions of the upper and lower blades 7 face the horizontal direction, so that the air flow 11d near the outlet 2 is deflected in the horizontal direction.
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、暖房時に吹出し口２から気流を下方向に吹出す場合について説明する。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６は図１の空気調和機の吹出し口２から気流を下方向に吹出したときの吹出し口２付近を示した説明図である。
上下羽根７は、回転軸７ａを中心に回動され、下方向に向けられる。
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。
回転軸９ａを中心に上面風向偏向板９を回動させて、上面風向偏向板９の先端部を上下羽根７の上面に指向させる。なお、下面風向偏向板１０は風路３の下壁の形状に合うように回動させて、上下羽根７の下面に沿った気流には影響を与えないようになっている。 Next, the case where an airflow is blown downward from the blower outlet 2 at the time of heating is demonstrated. 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. 6 is an explanatory view showing the vicinity of the air outlet 2 when the airflow is blown downward from the air outlet 2 of the air conditioner of FIG.
The upper and lower blades 7 are rotated about the rotation shaft 7a and directed downward.
The air that has passed through the heat exchanger 6 is carried by the fan 5 to the wind direction deflecting means 8.
The upper surface wind direction deflecting plate 9 is rotated around the rotation shaft 9 a so that the tip of the upper surface wind direction deflecting plate 9 is directed to the upper surfaces of the upper and lower blades 7. The lower surface wind direction deflecting plate 10 is rotated so as to match the shape of the lower wall of the air passage 3 so that the airflow along the lower surface of the upper and lower blades 7 is not affected.

ファン５により発生した気流１２ａは、風路３の形状に合った方向を向いており、上面風向偏向板９の下面と衝突して偏向される。上面風向偏向板９の下面と衝突した気流１２ｂは、上下羽根７に向かった方向となる。上下羽根７に向かって偏向された気流１２ｂは、上下羽根７の上面に衝突し、上述した上下羽根７の下面と衝突した気流と同様にして、気流が縮流し、気流の速度が増加する。
上下羽根７の先端部は下方向を向いているので、吹出し口２付近での気流１２ｃは、下方向に偏向され、狭い吹出し幅から速い速度で吹出される。
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の上面から横方向に吹き抜けることを抑制し、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 12 a generated by the fan 5 is directed in a direction that matches the shape of the air passage 3 and is deflected by colliding with the lower surface of the upper surface wind direction deflecting plate 9. The airflow 12 b that collides with the lower surface of the upper surface wind direction deflecting plate 9 is directed toward the upper and lower blades 7. The airflow 12b deflected toward the upper and lower blades 7 collides with the upper surface of the upper and lower blades 7, and the airflow contracts in the same manner as the airflow that collides with the lower surface of the upper and lower blades 7 described above, and the velocity of the airflow increases.
Since the tip portions of the upper and lower blades 7 are directed downward, the air flow 12c in the vicinity of the outlet 2 is deflected downward and is blown out at a high speed from a narrow blowing width.
In this way, when the airflow is deflected downward using the upper and lower blades 7, the upper surface wind direction deflecting plate 9 suppresses the airflow from blowing laterally from the upper surface of the upper and lower blades 7, and the air velocity is reduced by the contraction of the airflow. Therefore, a sufficient amount of airflow can be sent far.

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。   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.

また、風向偏向手段８は、風路３の下壁に回動可能に設けられ、先端部が上下羽根７の下面に指向する下面風向偏向板１０を有し、風路３の上壁に回動可能に設けられ、先端部が上下羽根７の上面に指向する上面風向偏向板９を有しているので、簡単な構成で、風路３内の気流を上下羽根７に向かって偏向させることができる。   Further, the wind direction deflecting means 8 is rotatably provided on the lower wall of the air path 3 and has a lower surface wind direction deflecting plate 10 whose tip is directed to the lower surface of the upper and lower blades 7. Since the upper surface wind direction deflecting plate 9 is provided so as to be movable and the front end portion faces the upper surface of the upper and lower blades 7, the air flow in the air passage 3 can be deflected toward the upper and lower blades 7 with a simple configuration. Can do.

図７（ａ）は実施の形態１に係る空気調和機の他の例を示す構成図、図７（ｂ）は実施の形態１に係る空気調和機のさらに他の例を示す構成図である。
上述した実施の形態１に係る空気調和機では、風向偏向手段８として、上面風向偏向板９および下面風向偏向板１０の両方を備えた空気調和機について説明したが、上面風向偏向板９のみを備えた空気調和機、または下面風向偏向板１０のみを備えた空気調和機であってもよい。 FIG. 7A is a configuration diagram illustrating another example of the air conditioner according to Embodiment 1, and FIG. 7B is a configuration diagram illustrating still another example of the air conditioner according to Embodiment 1. .
In the air conditioner according to Embodiment 1 described above, the air conditioner including both the upper surface wind direction deflecting plate 9 and the lower surface wind direction deflecting plate 10 has been described as the wind direction deflecting unit 8, but only the upper surface wind direction deflecting plate 9 is described. The air conditioner provided may be an air conditioner provided with only the lower surface wind direction deflecting plate 10.

図８は実施の形態１に係る空気調和機の風向偏向手段８の他の例を示す斜視図である。
風向偏向手段８の下面風向偏向板１０には、気流が通過できる貫通孔１３が複数形成されている。
図９（ａ）は、図８の貫通孔１３が形成されていない下面風向偏向板１０を備えたときの吹出し口２付近の説明図、図９（ｂ）は図８の貫通孔１３が形成された下面風向偏向板１０を備えたときの吹出し口２付近の説明図である。
なお、図３（ａ）、図３（ｂ）、図５、図９（ａ）および図９（ｂ）では、風路３の湾曲した壁を有するケース４を簡略し、直線で示している。
貫通孔１３が形成されていない下面風向偏向板１０を備えた空気調和機の場合、下面風向偏向板１０により気流の全てが上下羽根７に向かって偏向されるので、下面風向偏向板１０の下面へ、外部からの空気の巻き込みによる気流１６が生じる。
冷房時には、下面風向偏向板１０は、熱交換器６により冷却された気流の衝突により冷却されるので、温度の高い外部からの空気の巻き込みによる気流１６が下面風向偏向板１０に触れると、空気中の水分が凝縮され、下面風向偏向板１０の表面に結露する場合がある。
これに対して、貫通孔１３が形成された下面風向偏向板１０を備えた空気調和機の場合、気流１７が、下面風向偏向板１０により偏向されずに、貫通孔１３を通過するので、室内空気の巻き込みによる気流１６を抑制することができる。その結果、下面風向偏向板１０の表面に生じる結露を抑制することができる。 FIG. 8 is a perspective view showing another example of the wind direction deflecting means 8 of the air conditioner according to the first embodiment.
A plurality of through holes 13 through which airflow can pass are formed in the lower surface wind direction deflecting plate 10 of the wind direction deflecting means 8.
FIG. 9A is an explanatory view of the vicinity of the air outlet 2 when the lower surface wind direction deflecting plate 10 in which the through hole 13 of FIG. 8 is not formed is provided, and FIG. 9B is an illustration of the through hole 13 of FIG. It is explanatory drawing of the blower outlet 2 vicinity when the lower surface wind direction deflection | deviation plate 10 was provided.
3A, 3B, 5, 9A, and 9B, the case 4 having the curved wall of the air passage 3 is simplified and shown by a straight line. .
In the case of the air conditioner including the lower surface wind direction deflecting plate 10 in which the through-hole 13 is not formed, all of the airflow is deflected toward the upper and lower blades 7 by the lower surface wind direction deflecting plate 10. An air flow 16 is generated by the entrainment of air from the outside.
At the time of cooling, the lower surface wind direction deflecting plate 10 is cooled by the collision of the air flow cooled by the heat exchanger 6. Therefore, when the air flow 16 due to the entrainment of air from the outside having a high temperature touches the lower surface wind direction deflecting plate 10, In some cases, moisture in the inside is condensed and condensation is formed on the surface of the lower surface direction deflecting plate 10.
On the other hand, in the case of the air conditioner including the lower surface wind direction deflecting plate 10 in which the through hole 13 is formed, the air flow 17 passes through the through hole 13 without being deflected by the lower surface wind direction deflecting plate 10.
