(第1実施形態)

Embodiments of the present invention will be described in detail with reference to the drawings as appropriate. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.
(First embodiment)
FIG. 1 is a cycle configuration diagram of the air conditioner according to the first embodiment. During the cooling operation, the high-temperature and high-pressure refrigerant discharged from the compressor 34 flows into the outdoor heat exchanger 37 via the four-way valve 35. The refrigerant flowing into the outdoor heat exchanger 37 is condensed and becomes liquid refrigerant by exchanging heat with the outdoor air sent by the outdoor fan 38. The liquid refrigerant passes through the expansion valve 36 to become a low-temperature and low-pressure two-phase refrigerant and flows into the indoor heat exchanger 5. The low-temperature and low-pressure two-phase refrigerant that has flowed into the indoor heat exchanger 5 exchanges heat with the indoor air sent by the indoor blower fan 6. At this time, the indoor air sent to the indoor heat exchanger 5 is cooled by the low-temperature and low-pressure two-phase refrigerant flowing into the indoor heat exchanger 5 and discharged into the room from the outlet 3. Since the air discharged from the blower outlet 3 into the room is lower than the temperature of the air at the suction port 2, the room temperature can be lowered. The refrigerant heat-exchanged by the indoor heat exchanger 5 returns to the compressor 34 again via the four-way valve 35.
圧縮機34と室外熱交換器37と室外送風ファン38と膨張弁36は室外機に配置され、室内熱交換器5と室内送風ファン6は室内機1に配置されている。   The compressor 34, the outdoor heat exchanger 37, the outdoor blower fan 38, and the expansion valve 36 are arranged in the outdoor unit, and the indoor heat exchanger 5 and the indoor blower fan 6 are arranged in the indoor unit 1.
図2は第1実施形態に係る室内機の側面に沿った断面図である。空気調和機の室内機1は、吸込口2と吹出口3とを結ぶ空気通路4と、化粧枠13と、化粧枠13に固定され、室内機前面に配置された化粧パネル12を備える。さらに、空気調和機の室内機1は、化粧パネル12及び化粧枠13の内部であって、空気通路4に配置された室内熱交換器5と、化粧パネル12と室内熱交換器5の間に位置する前面側フィルタ14a、及び、上部化粧枠13aの下方に位置する上面側フィルタ14bから構成されるフィルタ14を備える。上面側フィルタ14bの直下には、塵埃が除去された空気と熱交換する室内熱交換器5が配置され、フィルタ14によって塵埃が除去された空気がΛ形状(逆V形状)の室内熱交換器5に流れる。室内の空気を吸い込む吸込口2は、室内機1本体の上部(化粧パネル12及び上面側フィルタ14bの上方)に位置し、吸込口2から吸い込まれた空気は塵埃を除去する上面側フィルタ14bに流れる。   FIG. 2 is a cross-sectional view along the side surface of the indoor unit according to the first embodiment. The indoor unit 1 of the air conditioner includes an air passage 4 connecting the suction port 2 and the air outlet 3, a decorative frame 13, and a decorative panel 12 that is fixed to the decorative frame 13 and arranged on the front surface of the indoor unit. Furthermore, the indoor unit 1 of the air conditioner is located inside the decorative panel 12 and the decorative frame 13 and between the indoor heat exchanger 5 disposed in the air passage 4 and between the decorative panel 12 and the indoor heat exchanger 5. The filter 14 comprised from the front surface side filter 14a located and the upper surface side filter 14b located under the upper decorative frame 13a is provided. An indoor heat exchanger 5 for exchanging heat with air from which dust has been removed is disposed directly below the upper surface side filter 14b, and the air from which dust has been removed by the filter 14 is an Λ-shaped (inverted V shape) indoor heat exchanger. Flows to 5. The air inlet 2 for sucking indoor air is located at the upper part of the indoor unit 1 main body (above the decorative panel 12 and the upper surface side filter 14b). Flowing.
化粧パネル12の下方には吹出口3が設けられ、熱交換された空気が吹出口3から室内機1の前方に吹き出される。室内送風ファン(送風用貫流ファン)6は、吸込口2から室内熱交換器5を経由して吹出口3へ向かう空気通路4であって、室内熱交換器5の下流側に配置され、吹出口3から熱交換された空気を吹き出す。   The blower outlet 3 is provided below the decorative panel 12, and the heat-exchanged air is blown out from the blower outlet 3 to the front of the indoor unit 1. The indoor air blower fan (airflow once-through fan) 6 is an air passage 4 from the suction port 2 to the air outlet 3 via the indoor heat exchanger 5 and is disposed on the downstream side of the indoor heat exchanger 5. Air that has undergone heat exchange is blown out from the outlet 3.
キャビネット15が壁面に固定される。室内熱交換器5の下側には、室内熱交換器5で結露した水を受けるドレンパン16が配置される。キャビネット15及びドレンパン16により、ファン6の下流側の空気通路4を発生させるための下流側風洞17が構成されている。   The cabinet 15 is fixed to the wall surface. A drain pan 16 that receives water condensed in the indoor heat exchanger 5 is disposed below the indoor heat exchanger 5. The cabinet 15 and the drain pan 16 constitute a downstream wind tunnel 17 for generating the air passage 4 on the downstream side of the fan 6.
下流側風洞17の上側には上側ケーシング18、下側には下側ケーシング11が配置される。上側ケーシング18は吹出口3の上部を構成し、下側ケーシング11は吹出口3の下部を構成する。   An upper casing 18 is disposed on the upper side of the downstream wind tunnel 17, and a lower casing 11 is disposed on the lower side. The upper casing 18 constitutes the upper part of the outlet 3, and the lower casing 11 constitutes the lower part of the outlet 3.
また、下流側風洞17のファン6側とは反対側の端面が吹出口3となる。左右風向板33、下流側風洞17の下側に配置された下側上下風向板10と、下流側風洞17の上側に配置された上側上下風向板9が吹出口3に配置されている。ここで、吹出口3に配置には、吹出口3の近傍の下流側風洞17に配置される場合が含まれる。下側上下風向板10は、制御部によって、運転停止時に吹出口3を閉じ、冷房運転時や暖房運転時に吹出口3を開ける。   Further, the end face of the downstream side wind tunnel 17 on the side opposite to the fan 6 side becomes the blowout port 3. A left and right wind direction plate 33, a lower vertical wind direction plate 10 disposed below the downstream side wind tunnel 17, and an upper vertical wind direction plate 9 disposed above the downstream side wind tunnel 17 are disposed at the outlet 3. Here, the arrangement at the air outlet 3 includes a case where it is arranged in the downstream wind tunnel 17 in the vicinity of the air outlet 3. The lower vertical wind direction plate 10 closes the air outlet 3 when the operation is stopped, and opens the air outlet 3 during the cooling operation or the heating operation, by the control unit.
上側上下風向板9は風路の中に配置されているため、冷房運転時上側上下風向板9の上面と下面に流れる空気に温度差が生じないため、上下風向板9が結露することはない。   Since the upper vertical wind direction plate 9 is disposed in the air passage, there is no temperature difference between the air flowing on the upper and lower surfaces of the upper vertical wind direction plate 9 during the cooling operation, so the vertical wind direction plate 9 does not condense. .
一方、下側上下風向板10は上面と下面で温度差が生じるため、結露が生じる。そのため、下側上下風向板10の上面と下面の熱の伝達を防ぐため、下側上下風向板10は熱抵抗が大きいウレタンフォームなどの断熱材28を挟んで構成される。   On the other hand, the lower vertical wind direction plate 10 has a temperature difference between the upper surface and the lower surface, and thus condensation occurs. Therefore, in order to prevent heat transfer between the upper and lower surfaces of the lower vertical wind direction plate 10, the lower vertical wind direction plate 10 is configured with a heat insulating material 28 such as urethane foam having a large thermal resistance interposed therebetween.
次に、上下風向板の動作について、図3、図4を用いて説明する。図3は、第1実施形態に係る室内機吹出口の能力優先モード時における拡大側面断面図である。能力優先モードについては、冷房運転時または暖房運転時の設定温度と室内温度との差が大きく、大きな冷房能力または暖房能力が必要となる場合に使用する。   Next, the operation of the vertical wind direction plate will be described with reference to FIGS. FIG. 3 is an enlarged side sectional view in the capacity priority mode of the indoor unit outlet according to the first embodiment. The capacity priority mode is used when the difference between the set temperature during the cooling operation or the heating operation and the room temperature is large and a large cooling capacity or heating capacity is required.
例えば、冷房運転または暖房運転の運転開始時に設定温度と室温が所定以上の差があるときに使用する。冷房能力および暖房能力は吸込口2と吹出口3の温度差と風量の積で決定され、風量が多い方がより冷房能力・暖房能力は高くなる。このとき室内送風ファン6の回転数を上昇させることで風量は多くなるが同時に騒音も上昇する。つまり送風効率を上げることができれば低騒音で能力を上昇させることができる。   For example, it is used when there is a difference between the set temperature and the room temperature at a predetermined level or more at the start of cooling operation or heating operation. The cooling capacity and the heating capacity are determined by the product of the temperature difference between the air inlet 2 and the air outlet 3 and the air volume, and the air capacity increases as the air volume increases. At this time, increasing the number of rotations of the indoor fan 6 increases the air volume, but at the same time increases the noise. That is, if the ventilation efficiency can be increased, the performance can be increased with low noise.
能力優先モード時には、下側上下風向板の軸21を中心に下側上下風向板10を回動し、下側上下風向板10の上流側端部上面26aが下側ケーシング11の延長線上又は下側ケーシング11の延長線より下方に位置するように配置される。これにより、下流側風洞17を通過する冷風22または温風23の送風抵抗が小さくでき、吹き出し風量を低下させることなく、効率良く室内に冷風22または温風23を送り出すことができる。上側上下風向板9及び下側上下風向板10については、ステップモータ24などの駆動部品25により上側上下風向板の軸20及び下側上下風向板の軸21を中心に回動する。下側上下風向板10の上面とは、下側上下風向板10のうち上側上下風向板9側の面をいう。   In the capacity priority mode, the lower vertical wind direction plate 10 is rotated about the shaft 21 of the lower vertical wind direction plate, and the upstream end upper surface 26a of the lower vertical wind direction plate 10 is above or below the extension line of the lower casing 11. It arrange | positions so that it may be located below the extension line of the side casing 11. As a result, the blowing resistance of the cold air 22 or the hot air 23 passing through the downstream wind tunnel 17 can be reduced, and the cold air 22 or the hot air 23 can be efficiently sent out into the room without reducing the amount of blown air. The upper vertical wind direction plate 9 and the lower vertical wind direction plate 10 are rotated around a shaft 20 of the upper vertical wind direction plate and a shaft 21 of the lower vertical wind direction plate by a driving component 25 such as a step motor 24. The upper surface of the lower vertical wind direction plate 10 refers to the surface of the lower vertical wind direction plate 10 on the upper vertical wind direction plate 9 side.
下側ケーシング11及び下側上下風向板10の側面に沿った断面形状については、下側上下風向板10が下側ケーシング11の略延長線上であれば、直線形状でも曲線形状でもよい。なお、下側上下風向板10の上流側端部上面26aが下側ケーシング11の延長線上になるよう配置するほうが好ましい。   About the cross-sectional shape along the side surface of the lower casing 11 and the lower up-and-down wind direction board 10, if the lower up-and-down wind direction board 10 is on the substantially extension line of the lower casing 11, a linear shape or a curve shape may be sufficient. In addition, it is more preferable to arrange the upstream end portion upper surface 26 a of the lower up-down wind direction plate 10 so as to be on the extension line of the lower casing 11.
下側上下風向板10は上下風向板軸21を中心に回動するため、下側上下風向板10と下側ケーシング11は干渉しない程度のクリアランスが必要である。クリアランスは下側上下風向板10の製品寸法のばらつきや反りの管理値以上にする必要があるが、下側上下風向板10をディフューザとして使用するためにはクリアランスは極力小さい方がよい。クリアランスが大きいとクリアランス部分から冷風22または温風23が漏れてしまい本来静圧として回収される動圧が周囲の空気に運動エネルギを与えてしまい静圧回収が有効に行われなくなる。   Since the lower vertical wind direction plate 10 rotates around the vertical wind direction plate shaft 21, a clearance that does not interfere with the lower vertical wind direction plate 10 and the lower casing 11 is required. The clearance needs to be equal to or greater than the management value of the product size variation and warpage of the lower vertical wind direction plate 10, but in order to use the lower vertical wind direction plate 10 as a diffuser, the clearance should be as small as possible. If the clearance is large, the cold air 22 or the hot air 23 leaks from the clearance portion, and the dynamic pressure originally recovered as static pressure gives kinetic energy to the surrounding air, so that the static pressure recovery cannot be performed effectively.
クリアランスが十分に小さい場合、ベルヌーイの定理から吹出口3は室内機1の周囲の圧力よりも小さくなるので、クリアランス部分は吹出口3に流入する流入空気39の流れ(下方から上方に向かう流れ)が生じる。   When the clearance is sufficiently small, the outlet 3 is smaller than the pressure around the indoor unit 1 according to Bernoulli's theorem, so the clearance portion is the flow of the inflowing air 39 flowing into the outlet 3 (flow from below to above). Occurs.
しかし、クリアランスが大きくなると、下側ケーシング11に沿って流れる冷風22・温風23が拡散しようとする流れが、吹出口3に流入する流れに勝り、クリアランス部分から冷風22または温風23が漏れてしまい、周囲の空気に運動エネルギを与えてしまう。また、流入空気39も運動エネルギを与えられるので少ない方がよい。以上の理由から前記クリアランスは小さい方が望ましく、静圧回収を有効に行うためにはクリアランスは2mm以下にすることが好ましい。   However, when the clearance is increased, the flow of the cold air 22 and the hot air 23 flowing along the lower casing 11 is more excellent than the flow flowing into the air outlet 3, and the cool air 22 or the hot air 23 leaks from the clearance portion. This gives kinetic energy to the surrounding air. Further, the inflowing air 39 is preferably less because it is given kinetic energy. For the above reasons, it is desirable that the clearance is small. In order to effectively recover the static pressure, the clearance is preferably 2 mm or less.
なお、上側上下風向板9については、送風抵抗を小さくするため、下側上下風向板10に略平行の姿勢とすることが好ましい。   In addition, about the upper up-and-down wind direction board 9, it is preferable to set it as a substantially parallel attitude | position to the lower up-and-down wind direction board 10 in order to make ventilation resistance small.
図4は、第1実施形態に係る室内機吹出口の通常冷房運転モード時における拡大側面断面図である。通常冷房運転モードは、大きな冷房能力を必要としない場合や、室内空気の湿度が高い場合に使用する。下側上下風向板10には熱抵抗が大きいウレタンフォーム等の断熱材28が挟まれ構成されているが、長時間下側上下風向板10の上面と下面で温度差を生じている場合や、湿度が高い状態が続くと下側上下風向板10が結露する懸念が生じる。   FIG. 4 is an enlarged side cross-sectional view of the indoor unit outlet according to the first embodiment in the normal cooling operation mode. The normal cooling operation mode is used when a large cooling capacity is not required or when the indoor air humidity is high. A heat insulating material 28 such as urethane foam having a large thermal resistance is sandwiched between the lower vertical wind direction plate 10, and when there is a temperature difference between the upper and lower surfaces of the lower vertical wind direction plate 10 for a long time, When the humidity remains high, there is a concern that the lower vertical wind direction plate 10 is condensed.
そこで、本実施例では、設定温度と室温の差が所定の値以下の場合、または湿度が所定の値以上の時に、通常冷房運転モードとし、下側上下風向板10の上流側端部上面26aが下側ケーシング11の延長線より上方に位置するよう下側上下風向板10を配置する。通常冷房運転モードにおける下側上下風向板10と下側ケーシング11の間の距離は、能力優先モードにおける下側上下風向板10と下側ケーシング11の間の距離より長い。   Therefore, in this embodiment, when the difference between the set temperature and the room temperature is equal to or lower than a predetermined value, or when the humidity is equal to or higher than the predetermined value, the normal cooling operation mode is set, and the upper surface 26a on the upstream end of the lower vertical wind direction plate 10 The lower up-and-down wind direction plate 10 is arranged so that is positioned above the extension line of the lower casing 11. The distance between the lower vertical wind direction plate 10 and the lower casing 11 in the normal cooling operation mode is longer than the distance between the lower vertical wind direction plate 10 and the lower casing 11 in the capacity priority mode.
温度の低い空気は、室内の低い位置に停留しやすい。低温の空気が、室内の低い位置に停留すると、使用者の足元のみが冷え、使用者に不快感を与える恐れがある。通常冷房運転モード時は、空気調和機の室内機1から室内の高い位置に冷風22を吹き出し、室内全体の温度を下げることが望ましい。このため、能力優先モード時の下側上下風向板10の位置より、下側上下風向板の軸21を中心に5〜25°上方に回動させた位置を、通常冷房運転モード時の下側上下風向板10の位置とする。上側上下風向板9については、送風抵抗を小さくするため、下側上下風向板10に略平行の姿勢とすることが好ましい。   Low-temperature air tends to stay at a low position in the room. When low-temperature air stops at a low position in the room, only the user's feet get cold, which may cause discomfort to the user. In the normal cooling operation mode, it is desirable to blow cool air 22 from the indoor unit 1 of the air conditioner to a high position in the room to lower the temperature of the entire room. For this reason, the position rotated 5 to 25 degrees above the shaft 21 of the lower vertical wind direction plate from the position of the lower vertical wind direction plate 10 in the capacity priority mode is the lower side in the normal cooling operation mode. The position of the vertical wind direction plate 10 is assumed. The upper vertical wind direction plate 9 is preferably in a posture substantially parallel to the lower vertical wind direction plate 10 in order to reduce blowing resistance.
下側ケーシング11の下流側には、下側上下風向板の上流側端部26が位置する。このとき、下側上下風向板10と下側ケーシング11の間に所定の隙間を設けているため、流入空気39の流れよりも冷風22が拡散しようとする流れが勝る。このため、下側ケーシング11に沿って冷風22が流れ、下側上下風向板の上流側端部26で下側上下風向板10の上側と下側に分かれて流れていく。下側上下風向板10の下側にも冷風22が流れるため、下側上下風向板10の上側も下側も略均一に冷やされる。これにより、下側上下風向板10の表面への結露を抑制することができる。   On the downstream side of the lower casing 11, the upstream end 26 of the lower vertical wind direction plate is located. At this time, since a predetermined gap is provided between the lower vertical wind direction plate 10 and the lower casing 11, the flow in which the cold air 22 tries to diffuse is superior to the flow of the incoming air 39. For this reason, the cool air 22 flows along the lower casing 11 and flows separately on the upper side and the lower side of the lower vertical wind direction plate 10 at the upstream end portion 26 of the lower vertical wind direction plate. Since the cool air 22 also flows below the lower vertical wind direction plate 10, the upper side and the lower side of the lower vertical wind direction plate 10 are cooled substantially uniformly. Thereby, the dew condensation on the surface of the lower up-and-down wind direction board 10 can be controlled.
下側上下風向板の軸21は下側上下風向板10の上流側で上側ケーシング18と下側ケーシング10との間に位置する。下側上下風向板の軸21と下側上下風向板10の間の距離は、通常冷房運転モードにおける下側上下風向板10と下側ケーシング11の間の距離より長い。具体的には、下側上下風向板10の上流側端部26と下側ケーシング11との間の隙間は、5〜15mmとすることが好ましい。これにより、通常冷房運転モード時に下側上下風向板10の下側にも冷風22が供給されやすくなる。   The shaft 21 of the lower vertical wind direction plate is located between the upper casing 18 and the lower casing 10 on the upstream side of the lower vertical wind direction plate 10. The distance between the shaft 21 of the lower vertical wind direction plate and the lower vertical wind direction plate 10 is longer than the distance between the lower vertical wind direction plate 10 and the lower casing 11 in the normal cooling operation mode. Specifically, the gap between the upstream end 26 of the lower vertical wind direction plate 10 and the lower casing 11 is preferably 5 to 15 mm. Thereby, the cool air 22 is easily supplied to the lower side of the lower vertical wind direction plate 10 in the normal cooling operation mode.
下側上下風向板10については、下側上下風向板の上流側端部下側26bにCカット面または曲面形状としても良い。これにより、通常冷房運転モード時に下側上下風向板10の下側に沿って流れる冷風22が、抵抗なく、よりスムーズに流れるようになる。   About the lower up-and-down wind direction board 10, it is good also as a C cut surface or a curved-surface shape in the upstream edge part lower side 26b of a lower up-and-down wind direction board. Thereby, the cool air 22 flowing along the lower side of the lower vertical wind direction plate 10 in the normal cooling operation mode flows more smoothly without resistance.
下側上下風向板10については、中空構造とし、内部に断熱材28を備えた構造としても良い。これにより、下側上下風向板10表面への結露の抑制効果を高めることができる。   The lower vertical wind direction plate 10 may have a hollow structure and a structure provided with a heat insulating material 28 inside. Thereby, the inhibitory effect of the dew condensation to the lower up-and-down wind direction board 10 surface can be heightened.
能力優先モードと通常冷房運転モードの切り替えは、使用者が実施する。また空気調和機の室内機1に備えた湿度センサ32によって、検知した湿度が予め設定された湿度(所定値)に達した場合に、自動で能力優先モードと通常冷房運転モードを切り替えても良い。湿度センサ32に加え、又は、湿度センサ32の代わりに、温度センサ31の検出値に応じて、能力優先モードと通常冷房運転モードを切り替えても良い。   Switching between the capacity priority mode and the normal cooling operation mode is performed by the user. Further, when the detected humidity reaches a preset humidity (predetermined value) by the humidity sensor 32 provided in the indoor unit 1 of the air conditioner, the capacity priority mode and the normal cooling operation mode may be automatically switched. . In addition to the humidity sensor 32 or instead of the humidity sensor 32, the capacity priority mode and the normal cooling operation mode may be switched according to the detection value of the temperature sensor 31.
運転開始直後は、結露が発生しないこと、及び、急速に室内を冷やす必要があることから、運転開始から所定時間は湿度センサ32又は湿度センサ32の検出値に係らず、強制的に能力優先モードを実行してもよい。   Immediately after the start of operation, condensation does not occur and it is necessary to cool the room rapidly. Therefore, the capacity priority mode is forcibly set regardless of the humidity sensor 32 or the detected value of the humidity sensor 32 for a predetermined time from the start of operation. May be executed.
なお、能力優先モードにおいて、室内送風ファン6の回転数を所定の値に変更してもよいし、能力優先モードの通常冷房運転モードの切り替えによって、室内送風ファン6の回転数を変えないようにしてもよい。   In the capacity priority mode, the rotation speed of the indoor blower fan 6 may be changed to a predetermined value, and the rotation speed of the indoor blower fan 6 is not changed by switching to the normal cooling operation mode in the capacity priority mode. May be.
能力優先モードと通常冷房運転モードとは、必ずしも使用者が設定できる特定の運転モードを構成する場合に限らず、1つの冷房運転モードにおいて、室温センサ31や湿度センサ32で検出された値に応じて、下側上下風向板10の位置を、能力優先モードにおける下側上下風向板10の位置と、通常冷房運転モードにおける下側上下風向板10の位置とに切り替えるよう構成してもよい。   The capacity priority mode and the normal cooling operation mode are not necessarily configured as a specific operation mode that can be set by the user, and depend on the values detected by the room temperature sensor 31 and the humidity sensor 32 in one cooling operation mode. Thus, the position of the lower vertical wind direction plate 10 may be switched between the position of the lower vertical wind direction plate 10 in the capacity priority mode and the position of the lower vertical wind direction plate 10 in the normal cooling operation mode.
このように本発明の第1実施形態によれば、空気調和機の室内機1において、室内空気を効率良く冷やす能力優先モードを備えつつ、室内空気の湿度が著しく高い場合には、通常冷房運転モードにより上下風向板10表面への結露を抑制することができる。   As described above, according to the first embodiment of the present invention, the indoor unit 1 of the air conditioner is provided with the capability priority mode for efficiently cooling the indoor air, and when the humidity of the indoor air is extremely high, the normal cooling operation is performed. Depending on the mode, condensation on the surface of the up-and-down wind direction plate 10 can be suppressed.
図5は、第1実施形態に係る室内機の運転停止時における側面に沿った断面図である。本実施形態における上側上下風向板9及び下側上下風向板10は、室内機1の筐体に沿うように曲線形状としている。そのため、空気調和機の運転停止時に、上側上下風向板9及び下側上下風向板10の下面が室内機1の意匠の一部となり、意匠面にも優れた構成にすることができる。   FIG. 5 is a cross-sectional view along the side surface when the indoor unit according to the first embodiment is stopped. The upper vertical wind direction plate 9 and the lower vertical wind direction plate 10 in the present embodiment are curved so as to follow the housing of the indoor unit 1. Therefore, when the operation of the air conditioner is stopped, the lower surfaces of the upper vertical wind direction plate 9 and the lower vertical wind direction plate 10 become a part of the design of the indoor unit 1, and the design surface can be excellent.
空気調和機の運転停止時に図5に示すように、下側上下風向板10の下面が室内機1の意匠外観を構成する表面の一部となり、通常冷房運転モード時に下側上下風向板10を図4に示す位置とし、能力優先モード時に図3に示す位置とするために、下側上下風向板10の回動する下側上下風向板の軸21は、下側上下風向板10よりも風上側であって、下側ケーシング11と上側ケーシング18の間に配置している。   As shown in FIG. 5 when the operation of the air conditioner is stopped, the lower surface of the lower vertical wind direction plate 10 becomes a part of the surface constituting the design appearance of the indoor unit 1, and the lower vertical wind direction plate 10 is moved in the normal cooling operation mode. In order to obtain the position shown in FIG. 4 and the position shown in FIG. 3 in the capacity priority mode, the shaft 21 of the lower upper and lower wind direction plate on which the lower upper and lower wind direction plate 10 rotates is winded more than the lower upper and lower wind direction plate 10. The upper casing is disposed between the lower casing 11 and the upper casing 18.
ディフューザとして静圧回収を目的とする場合、下側上下風向板10は長いほど効果が得られるが、下側上下風向板の軸21と離れているため、上下風向板10を回動させるためには大きなトルクが必要になる。下側上下風向板10を回動させるステップモータ24のトルクが不足した場合、減速機を介せばトルクを上昇させることができるが、減速比が大きければ大きいほど減速機が大きくなる。つまり、下側上下風向板10をディフューザとして使用する場合、ディフューザの効果を最大限得る構造は、減速機が室内機1に収まる大きさで減速比を大きくし、下側上下風向板10を回動させることができるトルクの上限まで下側上下風向板を長くすることである。なお、ステップモータ24及び減速機を下側ケーシング11の背面側で、且つ、下部化粧枠13bの上方に位置させてもよい。ステップモータ24及び減速機が気流の障害になるのを避けつつ、下側上下風向板の軸21のトルクを上昇させることができる。なお、下側ケーシング11の背面側とは、下流側風洞17の背面側の空間をいう。
(第2実施形態)
第2実施形態が、第1実施形態と異なる点は、第2実施形態の下側ケーシング11が、第1傾斜部29と、第1傾斜部29より下流側(先端側)に位置する第2傾斜部30を有する点である。第2傾斜部30は、第1傾斜部29に比べて、先端側が床面方向に傾斜している。
When aiming at static pressure recovery as a diffuser, the longer the lower vertical wind direction plate 10 is, the longer the effect is. However, since the lower vertical wind direction plate 10 is further away from the shaft 21, Requires a large torque. When the torque of the step motor 24 that rotates the lower vertical wind direction plate 10 is insufficient, the torque can be increased through the reduction gear, but the reduction gear becomes larger as the reduction ratio becomes larger. That is, when the lower up-and-down wind direction plate 10 is used as a diffuser, the structure for obtaining the maximum effect of the diffuser has a reduction gear ratio that is large enough to fit the reducer in the indoor unit 1, and the lower up-and-down wind direction plate 10 is rotated. The lower vertical wind direction plate is lengthened to the upper limit of the torque that can be moved. Note that the step motor 24 and the speed reducer may be positioned on the back side of the lower casing 11 and above the lower decorative frame 13b. The torque of the shaft 21 of the lower vertical wind direction plate can be increased while avoiding that the step motor 24 and the speed reducer obstruct the airflow. The back side of the lower casing 11 refers to the space on the back side of the downstream wind tunnel 17.
(Second Embodiment)
The second embodiment is different from the first embodiment in that the lower casing 11 of the second embodiment is the first inclined portion 29 and the second inclined portion 29 is located on the downstream side (front end side) from the first inclined portion 29. This is a point having an inclined portion 30. Compared to the first inclined portion 29, the second inclined portion 30 is inclined at the tip side in the floor surface direction.
次に、第2実施形態の上下風向板の動作について、図6乃至図8を用いて説明する。図6は、第2実施形態に係る室内機吹出口の能力優先モード時における拡大側面断面図である。能力優先モード時には、下側上下風向板の軸21を中心に下側上下風向板10を回動し、下側上下風向板10の上面が前記下側ケーシング11の第1傾斜部29の延長線上又は前記下側ケーシングの延長線より下方に位置する。これにより、下流側風洞17を通過する熱交換された冷風22または温風23の送風抵抗が小さくなるため、吹き出し風量が低下することなく、効率良く室内に冷風22または温風23を送り出すことができる。上側上下風向板9及び下側上下風向板10については、第1実施形態と同様に、ステップモータ24などの駆動部品25により回動する。   Next, the operation of the up and down wind direction plate of the second embodiment will be described with reference to FIGS. FIG. 6 is an enlarged side sectional view in the capacity priority mode of the indoor unit outlet according to the second embodiment. In the capacity priority mode, the lower vertical wind direction plate 10 is rotated about the shaft 21 of the lower vertical wind direction plate, and the upper surface of the lower vertical wind direction plate 10 is on the extension line of the first inclined portion 29 of the lower casing 11. Or it is located below the extension line of the lower casing. As a result, the blowing resistance of the heat-exchanged cold air 22 or hot air 23 passing through the downstream wind tunnel 17 is reduced, so that the cool air 22 or the hot air 23 can be efficiently sent into the room without reducing the amount of blown air. it can. The upper vertical wind direction plate 9 and the lower vertical wind direction plate 10 are rotated by a driving component 25 such as a step motor 24 as in the first embodiment.
下側ケーシング11の第1傾斜部29及び下側上下風向板10の側面に沿った断面形状については、下側上下風向板10が下側ケーシング11の第1傾斜部29の略延長線上であれば、直線形状でも曲線形状でも可とする。このときに、下側上下風向板の上流側端部26と下側ケーシング11の第1傾斜部29との間の隙間については、第1実施携帯同様2mm以下と小さい方が好ましい。   Regarding the cross-sectional shapes along the first inclined portion 29 of the lower casing 11 and the side surfaces of the lower vertical wind direction plate 10, the lower vertical wind direction plate 10 may be on a substantially extended line of the first inclined portion 29 of the lower casing 11. For example, a linear shape or a curved shape is acceptable. At this time, the gap between the upstream end 26 of the lower vertical wind direction plate and the first inclined portion 29 of the lower casing 11 is preferably as small as 2 mm or less as in the first embodiment.
上側上下風向板9についても、送風抵抗を小さくするため、下側上下風向板10に略平行の姿勢とすることが好ましい。   The upper vertical wind direction plate 9 is also preferably in a posture substantially parallel to the lower vertical wind direction plate 10 in order to reduce blowing resistance.
図7は、第2実施形態に係る室内機吹出口の通常冷房運転モード時における拡大側面断面図である。通常冷房運転モードは、大きな冷房能力を必要としない場合や、室内空気の湿度が高い場合に使用する。   FIG. 7 is an enlarged side cross-sectional view of the indoor unit outlet according to the second embodiment in the normal cooling operation mode. The normal cooling operation mode is used when a large cooling capacity is not required or when the indoor air humidity is high.
第1実施形態と同様に、能力優先モード時の下側上下風向板10位置より、下側上下風向板の軸21を中心に5〜25°上方に回動させた位置を、通常冷房運転モード時の下側上下風向板10の位置とする。上側上下風向板9については、送風抵抗を小さくするため、下側上下風向板10に略平行の姿勢とすることが好ましい。   As in the first embodiment, a position rotated by 5 to 25 degrees around the shaft 21 of the lower vertical wind direction plate from the position of the lower vertical wind direction plate 10 in the capacity priority mode is set to the normal cooling operation mode. The lower vertical wind direction plate 10 is at the position of the hour. The upper vertical wind direction plate 9 is preferably in a posture substantially parallel to the lower vertical wind direction plate 10 in order to reduce blowing resistance.
下側上下風向板の上流側端部上面26aが下側ケーシング11の第1傾斜部29の延長線より上方に位置する。このため、下側ケーシング11の第1傾斜部29に沿って流れる冷風22については、下側上下風向板の上流側端部26で下側上下風向板10の上側と下側に分かれて流れていく。このとき、冷風22の一部はコアンダ効果によって第1傾斜部29から第2傾斜部30、下側上下風向板10の下側に沿って第1実施形態よりも効果的に下側上下風向板10の下側にも冷風が流れるため、下側上下風向板10の上側も下側も略均一に冷やされる。これにより下側上下風向板10の表面への結露を抑制できる。   The upper surface 26 a of the upstream end portion of the lower vertical wind direction plate is located above the extension line of the first inclined portion 29 of the lower casing 11. For this reason, the cold air 22 flowing along the first inclined portion 29 of the lower casing 11 flows separately on the upper and lower sides of the lower vertical wind direction plate 10 at the upstream end portion 26 of the lower vertical wind direction plate. Go. At this time, a part of the cool air 22 is more effectively lower than the first embodiment from the first inclined portion 29 to the second inclined portion 30 along the lower side of the lower vertical wind direction plate 10 by the Coanda effect. Since the cool air also flows below 10, the upper and lower sides of the lower vertical wind direction plate 10 are cooled substantially uniformly. Thereby, the dew condensation on the surface of the lower up-and-down wind direction board 10 can be controlled.
前記下側上下風向板の上流側端部26と下側ケーシング11の第1傾斜部29との間の隙間については、5〜15mmとすることが好ましい。これにより、通常冷房運転モード時に下側上下風向板10の下側にも冷風が供給されやすくなる。   The gap between the upstream end 26 of the lower vertical wind direction plate and the first inclined portion 29 of the lower casing 11 is preferably 5 to 15 mm. Thereby, it becomes easy to supply cold air also to the lower side of the lower vertical wind direction plate 10 in the normal cooling operation mode.
下側上下風向板10については、下側上下風向板の上流側端部下側26bにCカット面または曲面形状としても良い。これにより、通常冷房運転モード時に下側上下風向板10の下側に沿って流れる冷風22が、抵抗なく、よりスムーズに流れるようになる。   About the lower up-and-down wind direction board 10, it is good also as a C cut surface or a curved-surface shape in the upstream edge part lower side 26b of a lower up-and-down wind direction board. Thereby, the cool air 22 flowing along the lower side of the lower vertical wind direction plate 10 in the normal cooling operation mode flows more smoothly without resistance.
前記下側上下風向板10については、中空構造とし、内部に断熱材28を備えた構造としても良い。これにより、下側上下風向板10表面への結露の抑制効果を高めることができる。   The lower vertical wind direction plate 10 may have a hollow structure and a structure provided with a heat insulating material 28 inside. Thereby, the inhibitory effect of the dew condensation to the lower up-and-down wind direction board 10 surface can be heightened.
図8は、第2実施形態に係る室内機吹出口の通常暖房運転モード時における拡大側面断面図である。通常暖房運転モードは、大きな暖房能力を必要としない場合や、室内空気の温度が設定温度に近づいた場合に使用する。温度の高い空気は、室内の高い位置に停留しやすい。高温の空気が、室内の高い位置に停留すると、使用者の頭部付近の空気が高温となり、使用者の足元は暖かくならず、不快感を与える恐れがある。通常暖房運転モード時は、空気調和機の室内機1から室内の低い位置に温風23を吹き出し、使用者の足元から暖めることが望ましい。このため、通常暖房運転モード時には、下側上下風向板の軸21を中心に前記下側上下風向板10を回動し、前記下側上下風向板10の上面が前記下側ケーシング11の第2傾斜部30の延長線上又は第2傾斜部30の延長線より下方となるように配置する。このときの下側上下風向板10位置は、前記能力優先モード時の下側上下風向板10位置より、軸を中心に5〜30°下方に回動させた位置とするのが望ましい。上側上下風向板9については、下側上下風向板10に略平行の姿勢とすることが望ましい。   FIG. 8 is an enlarged side cross-sectional view of the indoor unit outlet according to the second embodiment in the normal heating operation mode. The normal heating operation mode is used when a large heating capacity is not required or when the temperature of the room air approaches the set temperature. High-temperature air tends to stop at a high position in the room. When hot air stops at a high position in the room, the air near the user's head becomes hot, and the user's feet are not warm, which may cause discomfort. In the normal heating operation mode, it is desirable to blow warm air 23 from the indoor unit 1 of the air conditioner to a lower position in the room to warm it from the user's feet. Therefore, in the normal heating operation mode, the lower vertical wind direction plate 10 is rotated around the shaft 21 of the lower vertical wind direction plate, and the upper surface of the lower vertical wind direction plate 10 is the second side of the lower casing 11. It arrange | positions so that it may become below the extension line of the inclination part 30, or the extension line of the 2nd inclination part 30. FIG. At this time, the lower vertical wind direction plate 10 position is preferably a position rotated about 5 to 30 degrees around the axis from the lower vertical wind direction plate 10 position in the capacity priority mode. It is desirable that the upper vertical wind direction plate 9 has a posture substantially parallel to the lower vertical wind direction plate 10.
温風23は下側ケーシング11を沿って流れ下側ケーシングの第1傾斜部、下側ケーシングの第2傾斜部を経てコアンダ効果によって下側上下風向板10の上面を沿って流れ室内の低い位置に温風23を吹き出す。   The warm air 23 flows along the lower casing 11 and flows along the upper surface of the lower vertical wind direction plate 10 by the Coanda effect through the first inclined portion of the lower casing and the second inclined portion of the lower casing. Hot air 23 is blown out.
下側上下風向板10をディフューザとして下側ケーシング11の延長線上となるように配置しているが、上側上下風向板9を上側ケーシング18の延長線上となるように配置しても同様にディフューザとしての効果を得ることができる。しかしながら、冷風22・温風23は下側ケーシング11に沿って流れるため下側上下風向板10と同等のディフューザとしての効果は得られない。   Although the lower vertical wind direction plate 10 is disposed as an extension line of the lower casing 11 as a diffuser, the upper vertical wind direction plate 9 is similarly disposed as a diffuser even when positioned so as to be an extension line of the upper casing 18. The effect of can be obtained. However, since the cool air 22 and the warm air 23 flow along the lower casing 11, an effect as a diffuser equivalent to the lower vertical wind direction plate 10 cannot be obtained.
空気調和機の運転停止時は図5に示すように下側上下風向板10の下面が室内機1の意匠の一部となり、通常冷房運転モード時に下側上下風向板10を図4若しくは図7に示す位置とし、能力優先モード時に下側上下風向板10を図3若しくは図6に示す位置とし、通常暖房運転モード時に下側上下風向板10を図8に示す位置にするために、下側上下風向板10の回動する下側上下風向板の軸21は、下側上下風向板10よりも風上側であって、下側ケーシング11と上側ケーシング18の間に配置している。   When the operation of the air conditioner is stopped, as shown in FIG. 5, the lower surface of the lower vertical wind direction plate 10 becomes a part of the design of the indoor unit 1, and the lower vertical wind direction plate 10 is moved to the lower vertical wind direction plate 10 in the normal cooling operation mode. In order to set the lower vertical wind direction plate 10 to the position shown in FIG. 3 or FIG. 6 in the capacity priority mode and the lower vertical wind direction plate 10 to the position shown in FIG. The shaft 21 of the lower vertical wind direction plate on which the vertical wind direction plate 10 rotates is located on the windward side of the lower vertical wind direction plate 10 and is disposed between the lower casing 11 and the upper casing 18.
第1実施形態と同様に、能力優先モードと通常冷房運転モードと通常暖房運転モードの切り替えは、使用者が実施する。また、空気調和機の室内機1に備えた室温センサ31と湿度センサ32によって、検知した室温と湿度によって、予め設定された室温・湿度に達した場合に、自動で能力優先モードと通常冷房運転モードと通常暖房運転モードを切り替えても良い。   As in the first embodiment, switching between the capacity priority mode, the normal cooling operation mode, and the normal heating operation mode is performed by the user. Moreover, when the preset room temperature / humidity is reached by the room temperature sensor 31 and the humidity sensor 32 provided in the indoor unit 1 of the air conditioner, the capacity priority mode and the normal cooling operation are automatically performed. The mode and the normal heating operation mode may be switched.
冷房運転開始時に能力優先モードは設定温度と室温が所定以上の差があるときに使用し、所定の温度差以内であれば通常冷房運転モードとなる。   When the cooling operation is started, the capacity priority mode is used when the set temperature and the room temperature have a predetermined difference or more. When the difference is within the predetermined temperature difference, the normal cooling operation mode is set.
能力優先モードから通常冷房運転モードへの遷移は設定温度と室温の差が所定の値以下の場合、または所定の時間中湿度が所定の値以上の時通常冷房運転モードの上下風向板の位置にし、下側上下風向板の10の下面に風を流し上面と下面の温度差をなくすことで結露を防止する。   The transition from the capacity priority mode to the normal cooling operation mode is performed when the difference between the set temperature and room temperature is less than the predetermined value, or when the humidity during the predetermined time is higher than the predetermined value, the position of the vertical airflow direction plate in the normal cooling operation mode. Condensation is prevented by flowing a wind on the lower surface of the lower vertical wind direction plate 10 and eliminating the temperature difference between the upper surface and the lower surface.
暖房運転開始時における能力優先モードは設定温度と室温が所定以上の差があるときに使用し、所定の温度差以内であれば通常暖房運転モードとなる。   The capacity priority mode at the start of the heating operation is used when there is a difference between the set temperature and the room temperature that is greater than or equal to a predetermined value.
能力優先モードから通常暖房運転モードへの遷移は設定温度と室温の差が所定の値以下の場合通常暖房運転モードの上下風向板の位置にし、空気調和機の室内機1から室内の低い位置に温風23を吹き出し、使用者の足元を温める。   The transition from the capacity priority mode to the normal heating operation mode is performed when the difference between the set temperature and the room temperature is equal to or less than a predetermined value. Hot air 23 is blown out to warm the user's feet.
