Description

本発明は、空気調和機に関する。   The present invention relates to an air conditioner.

空気調和機は、設置した室内の空気を熱交換器に循環させて、加熱,冷却,除湿機能等で調和空気にし、送風ファンによって室内に送風することで室内環境を調節する。   The air conditioner adjusts the indoor environment by circulating the air in the installed room to the heat exchanger, making the air conditioned by heating, cooling, dehumidifying functions, etc., and blowing the air indoors by a blower fan.

また、調和空気を室内ユニットから左右方向へ送風するために、室内ユニットの吹出口の略水平方向には、角度調節自在な複数の左右風向板が所定間隔で設置されている。この左右風向板の角度を制御することで、風向制御された調和空気が、所定の方向へと送風される。   Also, in order to blow conditioned air from the indoor unit in the left-right direction, a plurality of left and right wind direction plates whose angles can be adjusted are provided at predetermined intervals in the substantially horizontal direction of the air outlet of the indoor unit. By controlling the angle of the left and right wind direction plates, the conditioned air whose wind direction is controlled is blown in a predetermined direction.

室内ユニットにおける左右風向板と調和空気の流れの関係を、図26にて説明する。図26は、室内ユニットから送風する調和空気(以下、吹出空気)を、左右方向へ風向制御するときの、左右風向板の状態を示す図である。なお、図26における破線矢印は、吹出空気の流れを示す。   The relationship between the left and right wind direction plates and the flow of conditioned air in the indoor unit will be described with reference to FIG. FIG. 26 is a diagram illustrating a state of the left and right wind direction plates when the conditioned air blown from the indoor unit (hereinafter, blown air) is controlled in the left and right directions. In addition, the broken line arrow in FIG. 26 shows the flow of blowing air.

図26において、風向制御方向(吹出空気の風向上流から風向下流の方向。図26では上側から下側の方向)にbの長さをもつ左右風向板10が、室内ユニットの吹出口に設置される。左右風向板10は、それぞれピッチpの間隔で吹出口の左右方向に設置され、回転軸13で回動自在に軸支される。図26においては、風向上流側の一部がそれぞれ回動自在に軸支される。また、左右風向板10は、連結部材6によって連動するようにそれぞれ連結される。   In FIG. 26, left and right wind direction plates 10 having a length b in the wind direction control direction (the direction from the wind improving flow of the blown air to the downstream of the wind direction; the direction from the upper side to the lower side in FIG. 26) are installed at the outlet of the indoor unit. The The left and right wind direction plates 10 are installed in the left and right direction of the air outlet at intervals of a pitch p, and are pivotally supported by the rotation shaft 13. In FIG. 26, a part of the wind improving flow side is pivotally supported. Further, the left and right wind direction plates 10 are connected to each other so as to be interlocked by the connecting member 6.

この左右風向板10の左右方向への最大回転角度がαのとき、左右風向板10の寸法がそれぞれ等しければ、長さb,ピッチp、及び角度αによって、吹出空気の左右方向へ送風可能な範囲(風向制御角度β)が規定される。すなわち、風向制御角度βが大きいほど、室内ユニットを設置した室内の広範囲へ送風可能となる。   When the maximum rotational angle of the left and right wind direction plates 10 in the left and right direction is α, the left and right wind direction plates 10 can be blown in the left and right directions by the length b, the pitch p, and the angle α if the dimensions of the left and right wind direction plates 10 are equal. A range (wind direction control angle β) is defined. That is, as the wind direction control angle β is larger, the air can be blown to a wide area in the room where the indoor unit is installed.

ここで、風向制御角度βを大きくするために、長さbと角度αを大きくして、ピッチpを小さくすることが考えられる。しかし、長さbを大きくすると、吹出空気を正面方向へ送風するとき、通風抵抗が大きくなる。一方、ピッチpを小さくすると、左右風向板10の数が増加するため、如何なる風向制御状態においても通風抵抗が大きくなり、騒音が増加する。また、角度αを大きくすると、吹出空気の風路幅が狭くなるため、通風抵抗が増加し、騒音が増加する。   Here, in order to increase the wind direction control angle β, it is conceivable to increase the length b and the angle α to decrease the pitch p. However, if the length b is increased, the ventilation resistance increases when the blown air is blown in the front direction. On the other hand, when the pitch p is reduced, the number of the left and right wind direction plates 10 is increased, so that the ventilation resistance is increased and the noise is increased in any wind direction control state. Further, when the angle α is increased, the air passage width of the blown air is narrowed, so that the ventilation resistance is increased and noise is increased.

吹出空気の左右方向への風向制御技術として、従来、特許文献1〜3に記載のものがある。   Conventionally, there are those described in Patent Documents 1 to 3 as techniques for controlling the direction of the airflow in the left-right direction.

特許文献1には、室内ユニットの吹出口に設けられた主風向板と、主風向板内に収められ、前方または上方に延出する補助風向板とからなる左右風向板の構成が記載されている。   Patent Document 1 describes the configuration of a left and right wind direction plate composed of a main wind direction plate provided at an air outlet of an indoor unit and an auxiliary wind direction plate housed in the main wind direction plate and extending forward or upward. Yes.

特許文献2には、室内ファンからの送風を左または右方向へ案内する第一の湾曲部と、第一の湾曲部により案内された送風を元の方向へ戻すように案内する第二の案内部、とを備えた左右風向板の構成が記載されている。   In Patent Document 2, a first curved portion that guides the air blown from the indoor fan leftward or rightward, and a second guide that guides the airflow guided by the first curved portion back to the original direction. The structure of the left-right wind direction board provided with the part is described.

特許文献3には、吹出空気の風向角度を調整する偏向板の風下側端縁に凸部又は湾曲部を設けた構成が記載されている。   Patent Document 3 describes a configuration in which a convex portion or a curved portion is provided on the leeward side edge of a deflector plate that adjusts the wind direction angle of blown air.

特開2004−232943号公報JP 2004-232943 A 特開平8−159546号公報JP-A-8-159546 特開平5−71796号公報JP-A-5-71796

前述した従来技術は、風向板の寸法や形状によって、左右方向への送風範囲が規定される。すなわち、風向制御範囲(風向板回転角度)を拡大したり、風向板の数を増やしたり、風向板の寸法を拡大したりすると、通風抵抗や騒音が課題となる。   In the prior art described above, the air blowing range in the left-right direction is defined by the size and shape of the wind direction plate. That is, if the wind direction control range (wind direction plate rotation angle) is expanded, the number of wind direction plates is increased, or the size of the wind direction plate is increased, ventilation resistance and noise become problems.

特許文献1の構成は、主風向板に収められた補助風向板が上下風向板との距離を縮めるように延出して、冷風を下降させることなく遠くまで送風したり、温風を左右方向に送風したりしている。しかし、左右風向板の寸法や数,回転角度によって、吹出空気の左右方向への風向制御範囲は規定されるため、広範な風向制御を行うことは難しい。   The configuration of Patent Document 1 is such that the auxiliary wind direction plate housed in the main wind direction plate extends so as to reduce the distance from the upper and lower wind direction plates, and blows far away without lowering the cool air, or warm air in the left-right direction. I am blowing. However, since the range of the wind direction in the left and right direction of the blown air is defined by the size, number, and rotation angle of the left and right wind direction plates, it is difficult to perform a wide range of wind direction control.

特許文献2の構成は、左右風向板同士の湾曲部で送風の際に生じる騒音を反射させて減衰することで、送風騒音を低減している。しかし、正面方向への送風時に、湾曲部が通風抵抗となり、送風効率が低下するおそれがある。   The configuration of Patent Document 2 reduces blowing noise by reflecting and attenuating noise generated during blowing at the curved portion between the left and right wind direction plates. However, at the time of blowing in the front direction, the curved portion becomes a ventilation resistance, and there is a possibility that the blowing efficiency is lowered.

特許文献3の構成は、偏向調整板において凸部や湾曲部のない範囲では、偏向調整板の方向に送風され、凸部や湾曲部のある範囲では、その形状に沿って送風される。しかし、正面方向への送風時に、凸部や湾曲部では正面に送風できないため、送風効率が低下するおそれがある。   In the configuration of Patent Document 3, air is blown in the direction of the deflection adjustment plate in a range where there is no convex portion or curved portion in the deflection adjustment plate, and is blown along the shape in a range where there is a convex portion or curved portion. However, when the air is blown in the front direction, the air cannot be blown to the front at the convex portion or the curved portion, so that the air blowing efficiency may be reduced.

本発明は、上記課題を解決するものである。本発明の目的は、室内ユニットからの吹出空気を正面方向へ送風するときの通風抵抗を抑えて、かつ、風向板の寸法,数、及び回転角度で規定される左右方向の風向制御範囲よりも、広範な風向制御が可能な風向板を備えた空気調和機を提供することである。   The present invention solves the above problems. The object of the present invention is to suppress the airflow resistance when blowing the air blown from the indoor unit in the front direction, and more than the airflow direction control range in the left and right direction defined by the size, number and rotation angle of the airflow direction plate.

室内ユニット17がリモコン20からの運転信号を受信すると、室外機22も作動する。室外機22から送られた冷媒は、冷媒用銅パイプ14を介して熱交換器7を循環する。送風ファン8に連結するモータは、マイコン制御により、運転状態に合わせた駆動をする。   When the indoor unit 17 receives an operation signal from the remote controller 20, the outdoor unit 22 also operates. The refrigerant sent from the outdoor unit 22 circulates through the heat exchanger 7 via the refrigerant copper pipe 14. The motor connected to the blower fan 8 is driven according to the operating state by microcomputer control.

次に、空気の吸込みから吹出しの流れについて説明する。送風ファン8が、図2において右回りに回転すると、前面パネル1の開口部と上面グリル2から、室内空気が吸込まれる(以下、吸込空気)。そして、吸込空気は、プレフィルター4を通過して室内ユニット17の内部に流れる。吸込空気がプレフィルター4を通過するとき、同時に吸込まれた埃等が取り除かれる。プレフィルター4を通過した吸込空気は、プレフィルター4の内方の空清フィルター5を通過するとき、さらに清浄される。この過程を経て、吸込空気は熱交換器7へ流入し、熱交換された後、送風ファン8へ流れていく。送風ファン8へ流れた吹出空気は、送風ファン8の羽根間を通過して外径側から内径側へと流れる。さらに、吹出空気は送風ファン8の羽根間を通過して内径側から外径側へと向かい、ケーシング9側へ流れ出ていく。送風ファン8からの吹出空気は、ケーシング9の下流側に設けられた左右風向板,上下風向板11を通過して、風向制御されて室内に送風される。   Next, the flow of air blowing from the air suction will be described. When the blower fan 8 rotates clockwise in FIG. 2, room air is sucked from the opening of the front panel 1 and the top grill 2 (hereinafter, sucked air). Then, the intake air passes through the prefilter 4 and flows into the indoor unit 17. When the intake air passes through the pre-filter 4, the sucked dust and the like are removed at the same time. The suction air that has passed through the prefilter 4 is further cleaned when it passes through the air purification filter 5 inside the prefilter 4. Through this process, the intake air flows into the heat exchanger 7 and is exchanged for heat, and then flows into the blower fan 8. The blown air that has flowed to the blower fan 8 passes between the blades of the blower fan 8 and flows from the outer diameter side to the inner diameter side. Further, the blown air passes between the blades of the blower fan 8, travels from the inner diameter side to the outer diameter side, and flows out to the casing 9 side. The blown air from the blower fan 8 passes through the left and right wind direction plates 11 and the upper and lower wind direction plates 11 provided on the downstream side of the casing 9, and is blown into the room with the wind direction controlled.

一方、運転を停止するときは、送風ファン8の駆動を停止した後に、開閉用パネルと上下風向板を回動させて、開口を閉じるように制御する。   On the other hand, when the operation is stopped, after the driving of the blower fan 8 is stopped, the opening / closing panel and the vertical wind direction plate are rotated to control the opening to be closed.

また、熱交換器7の下方には、露受皿が配設されており、冷房運転時や除湿運転時に、熱交換器7に発生する凝縮水を受け止める。これにより集められた凝縮水は、ドレン配管23を通って室外に排出される。   In addition, a dew tray is disposed below the heat exchanger 7 and receives condensed water generated in the heat exchanger 7 during cooling operation or dehumidifying operation. The condensed water collected in this way is discharged to the outside through the drain pipe 23.

このように、室内空気の流路が形成される。すなわち、送風ファン8を駆動させることで、室内空気が吸込口16から吸込まれ、プレフィルター4,空清フィルター5を通過して、熱交換器7において熱交換された後、吹出口15から室内に吹出される。   In this way, a flow path for room air is formed. That is, by driving the blower fan 8, room air is sucked from the suction port 16, passes through the prefilter 4 and the air purification filter 5, and is heat-exchanged in the heat exchanger 7, and then enters the room from the blowout port 15. Be blown out.

このように、本発明は、熱交換を行う熱交換器と、風を送り出す送風ファン8と、左右方向の風向制御を行う左右風向板10とを、室内ユニット17に備えたセパレート型の空気調和機を前提とする。   As described above, the present invention is a separate type air conditioner in which the indoor unit 17 includes the heat exchanger that performs heat exchange, the blower fan 8 that sends out the wind, and the left and right wind direction plates 10 that perform the wind direction control in the left and right directions. The machine is assumed.

本発明に係る第1の実施例の空気調和機について、図1から図5にて説明する。   An air conditioner according to a first embodiment of the present invention will be described with reference to FIGS.

図3と図4は、図2に示すA断面を矢印方向から見た図である。すなわち、室内ユニット17の吹出口15における、左右風向板10の配列を示す図である。図3と図4の破線で囲んだ部分は、左右風向板10のひとつを拡大した図である。また、図3は、吹出空気を室内ユニット17から正面方向へ送風するときの左右風向板10の位置を示す図である。図4は、吹出空気を室内ユニット17から左方向へ送風するときの左右風向板10の位置を示す図である。   3 and 4 are views of the A cross section shown in FIG. 2 as viewed from the direction of the arrow. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. 3 and FIG. 4 is an enlarged view of one of the left and right wind direction plates 10. Moreover, FIG. 3 is a figure which shows the position of the left-right wind direction board 10 when blowing air is blown in the front direction from the indoor unit 17. FIG. FIG. 4 is a diagram showing the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

左右風向板10は、吹出口15の位置に、略水平方向に所定間隔で複数配列している。本実施例の左右風向板10は、吹出空気に対して、上流側左右風向板10aと下流側左右風向板10bとで構成される。また、上下方向へ風向制御を行うとき、上下風向板11は上下に回動する。すなわち、吹出口15からの吹出空気は、上流側左右風向板10aと下流側左右風向板10bから構成される左右風向板10と、上下風向板11とによって風向制御されて、目的とする方向へと送風される。   A plurality of the right and left wind direction plates 10 are arranged at predetermined intervals in the substantially horizontal direction at the position of the air outlet 15. The left and right wind direction plates 10 of the present embodiment are composed of upstream left and right wind direction plates 10a and downstream left and right wind direction plates 10b with respect to the blown air. Further, when the wind direction control is performed in the vertical direction, the vertical wind direction plate 11 rotates up and down. That is, the air blown from the blowout port 15 is controlled in the wind direction by the left and right wind direction plates 10 composed of the upstream left and right wind direction plates 10a and the downstream left and right wind direction plates 10b, and the up and down wind direction plates 11 in the intended direction. Is blown.

上流側左右風向板10aの風向上流側の一部は、回転軸13によって背部のケーシング9に回転自在に軸支される。すなわち、上流側左右風向板10aは、回転軸13を基点として左右方向に回動自在である。   A part of the upstream side wind direction plate 10 a on the wind improving flow side is rotatably supported on the casing 9 at the back by the rotating shaft 13. That is, the upstream left / right airflow direction plate 10a is rotatable in the left / right direction with the rotation shaft 13 as a base point.

上流側左右風向板10aは、風向下流側が開口した中空構造を有し、下流側左右風向板10bの一部は、この中空部に収納される。すなわち、本実施例における左右風向板10は、下流側左右風向板10bが、上流側左右風向板10aの中空部内を、風向上流から下流の方向に、滑動自在に構成される。また、下流側左右風向板10bは、吹出口15の略水平方向に配設される棒状の連結部材6で連結される。これにより、下流側左右風向板10bは、連結部材6の動作に連動する。   The upstream left / right wind direction plate 10a has a hollow structure with an opening on the downstream side in the wind direction, and a part of the downstream left / right wind direction plate 10b is accommodated in the hollow portion. That is, in the present embodiment, the left and right wind direction plates 10 are configured such that the downstream left and right wind direction plates 10b are slidable in the hollow portion of the upstream left and right wind direction plates 10a in the downstream direction from the wind improving flow. Further, the downstream left and right wind direction plates 10 b are connected by a rod-like connecting member 6 disposed in a substantially horizontal direction of the air outlet 15. Thereby, the downstream left and right wind direction plates 10 b are interlocked with the operation of the connecting member 6.

次に、正面風向制御(図3)から左右風向制御(図4)に移行するときの、左右風向板10の動作を説明する。左右風向制御を行うとき、連結部材6が左右方向,前後方向へ動くことにより、下流側左右風向板10bが連動する。上流側左右風向板10aは、下流側左右風向板10bに連動して、回転軸13を基点に回動する。そして、上流側左右風向板10aの中空部に収納された下流側左右風向板10bの部分が、風向下流側へと延出する。   Next, the operation of the left and right wind direction plate 10 when shifting from the front wind direction control (FIG. 3) to the left and right wind direction control (FIG. 4) will be described. When the left and right wind direction control is performed, the downstream left and right wind direction plates 10b are interlocked by moving the connecting member 6 in the left and right direction and the front and rear direction. The upstream left / right wind direction plate 10a rotates around the rotation shaft 13 in conjunction with the downstream left / right wind direction plate 10b. And the part of the downstream left-right wind direction board 10b accommodated in the hollow part of the upstream left-right wind direction board 10a extends to the wind direction downstream side.

このとき、上流側左右風向板10aと下流側左右風向板10bは、完全には離間せず、下流側左右風向板10bの少なくとも一部が、上流側左右風向板10aの中空部に収納された状態を保持可能な範囲で、下流側へと延出する。すなわち、左右風向板10全体は、左右方向への風向制御のときに、風の流れ方向(吹出空気の風向上流から下流の方向。図3,図4においては上側から下側の方向)へ伸長可能な構成である。   At this time, the upstream left / right wind direction plate 10a and the downstream left / right wind direction plate 10b are not completely separated, and at least a part of the downstream left / right wind direction plate 10b is accommodated in the hollow portion of the upstream left / right wind direction plate 10a. It extends downstream as long as the state can be maintained. That is, the entire left and right wind direction plate 10 extends in the wind flow direction (the direction downstream from the wind improvement flow of the blown air, from the upper side to the lower side in FIGS. 3 and 4) when the wind direction is controlled in the left and right direction. This is a possible configuration.

次に、左右風向制御(図4)から正面風向制御(図3)へ移行するときの、左右風向板10の動作を説明する。左右風向制御のとき、上述したように、下流側左右風向板10bの少なくとも一部が、上流側左右風向板10aの中空部に収納された状態を保持可能な範囲で、下流側左右風向板10bが風向下流側へと延出している。この状態から、連結部材6が左右風向制御のときとは反対方向に動作することで、左右風向板10が左右風向制御から正面風向制御の状態に移行する。このとき、下流側左右風向板10bにおける下流側へ延出していた部分は、次第に上流側左右風向板10aの中空部に収納される。   Next, the operation of the left and right wind direction plate 10 when shifting from the left and right wind direction control (FIG. 4) to the front wind direction control (FIG. 3) will be described. In the left / right wind direction control, as described above, the downstream left / right wind direction plate 10b is within a range in which at least a part of the downstream left / right wind direction plate 10b can be held in the hollow portion of the upstream left / right wind direction plate 10a. Extends downstream in the wind direction. From this state, when the connecting member 6 operates in the opposite direction to that in the left / right wind direction control, the left / right wind direction plate 10 shifts from the left / right wind direction control to the front wind direction control state. At this time, the portion of the downstream left and right wind direction plate 10b that extends to the downstream side is gradually accommodated in the hollow portion of the upstream left and right wind direction plate 10a.

図5は、室内ユニットの正面方向と左方向へ風向制御を行うときの、左右風向板10の動作を示した図である。正面方向送風時の左右風向板10を実線で示し、左方向送風時の左右風向板10を破線で示す。左右風向板10が、最大回転角度αの範囲で、正面方向送風時から左方向送風時の状態に移行する。このとき、下流側左右風向板10bが上流側左右風向板10aの中空部に収納された部分が次第に風向下流に延出することにより、左右風向板10全体が風の流れ方向へ伸長する。左右方向へ風向制御される吹出空気は、左右風向板10の流れ方向への長さ寸法が長くなることで、吹出角度を広角にできる。具体的に、左右風向板10の風向上流から下流方向における長さ寸法は、正面方向送風時にbであり、左方向送風時にb′である。そして、b′>bという関係にある。これにより、風向板の形状で規定される風向制御範囲よりも、広い範囲へ送風することができる。   FIG. 5 is a diagram illustrating the operation of the left and right wind direction plates 10 when the wind direction control is performed in the front direction and the left direction of the indoor unit. The left and right wind direction plates 10 when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10 when blowing in the left direction are indicated by broken lines. The left and right wind direction plates 10 shift from the front direction air blowing state to the left air blowing state within the range of the maximum rotation angle α. At this time, the portion of the downstream left and right wind direction plate 10b accommodated in the hollow portion of the upstream left and right wind direction plate 10a gradually extends downstream in the wind direction, so that the entire left and right wind direction plate 10 extends in the wind flow direction. The blown air whose wind direction is controlled in the left-right direction can be widened by increasing the length of the left-right wind direction plate 10 in the flow direction. Specifically, the length dimension in the downstream direction from the wind improving flow of the left and right wind direction plates 10 is b when blowing in the front direction and b 'when blowing in the left direction. The relationship is b ′> b. Thereby, it can blow to the range wider than the wind direction control range prescribed | regulated by the shape of a wind direction board.

一方、左右風向板10は正面方向送風時に通風抵抗となる。そこで本構成では、左右方向への風向制御を必要としないときは、左右風向板10の寸法bを、左右方向送風時の寸法b′よりも小さくすることにより、通風抵抗を低減できる。また、運転による騒音を最小限に抑えることができる。   On the other hand, the left and right wind direction plates 10 provide ventilation resistance when blowing in the front direction. Therefore, in this configuration, when it is not necessary to control the wind direction in the left-right direction, the ventilation resistance can be reduced by making the dimension b of the left-right wind direction plate 10 smaller than the dimension b ′ during the blowing in the left-right direction. In addition, noise due to driving can be minimized.

以上の構造により、風向板の寸法,数、及び回転角度によって規定される左右方向への風向制御よりも、広範な風向制御が可能となる。さらに、正面方向への送風時には、左右方向への送風時よりも、左右風向板の長さ寸法(吹出空気の上流から下流の方向への長さ寸法)を小さくすることで、通風抵抗を低減することができる。   With the above structure, a wider range of wind direction control is possible than the wind direction control in the left-right direction defined by the size, number, and rotation angle of the wind direction plate. Furthermore, when blowing in the front direction, the resistance to ventilation is reduced by reducing the length of the left and right wind direction plates (length from the upstream to the downstream of the blown air) than when blowing in the left and right directions. can do.

また、下流側左右風向板10bが、上流側左右風向板10aの中空部から脱落することを防止する為に、ストッパ構造を備えた左右風向板10が考えられる。一例として、下流側左右風向板10bの上流側の端部と、上流側左右風向板10aの下流側の端部に、段部を設ける構造が考えられる。これにより、空気調和機の風向制御時における信頼性を向上できる。   In order to prevent the downstream left / right wind direction plate 10b from dropping out of the hollow portion of the upstream left / right wind direction plate 10a, a left / right wind direction plate 10 having a stopper structure is conceivable. As an example, a structure in which stepped portions are provided at the upstream end of the downstream left and right wind direction plate 10b and the downstream end of the upstream left and right wind direction plate 10a is conceivable. Thereby, the reliability at the time of the wind direction control of an air conditioner can be improved.

本実施例は、下流側左右風向板10bが上流側左右風向板10aの中空部に収納される構成である。しかし、これに限られるものではなく、別の構成について図6から図9を用いて説明する。   In this embodiment, the downstream left / right wind direction plate 10b is housed in the hollow portion of the upstream left / right wind direction plate 10a. However, the present invention is not limited to this, and another configuration will be described with reference to FIGS.

図6は、室内ユニットの側断面図を示す。図7と図8は、図6に示すB断面を矢印方向から見た図である。すなわち、室内ユニット17の吹出口15における、左右風向板10の配列を示す図である。図7と図8の破線で囲んだ部分は、左右風向板10のひとつを拡大した図である。また、図7は、吹出空気を室内ユニット17から正面方向へ送風するときの左右風向板10の位置を示す図である。図8は、吹出空気を室内ユニット17から左方向へ送風するときの左右風向板10の位置を示す図である。   FIG. 6 shows a side sectional view of the indoor unit. 7 and 8 are views of the B cross section shown in FIG. 6 as viewed from the direction of the arrow. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. 7 and FIG. 8 is an enlarged view of one of the left and right wind direction plates 10. Moreover, FIG. 7 is a figure which shows the position of the left-right wind direction board 10 when blowing air is blown in the front direction from the indoor unit 17. FIG. FIG. 8 is a view showing the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

図9は、室内ユニットの正面方向と左方向へ風向制御を行うときの、左右風向板10の動作を示した図である。正面方向送風時の左右風向板10を実線で示し、左方向送風時の左右風向板10を破線で示す。   FIG. 9 is a diagram illustrating the operation of the left and right wind direction plates 10 when the wind direction control is performed in the front direction and the left direction of the indoor unit. The left and right wind direction plates 10 when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10 when blowing in the left direction are indicated by broken lines.

上記の構成と異なる点は、下流側左右風向板10dに風向上流側が開口した中空部が設けられ、この中空部に上流側左右風向板10cが収納される点である。   The difference from the above configuration is that the downstream left and right wind direction plate 10d is provided with a hollow portion having an open wind improving flow side, and the upstream left and right wind direction plate 10c is accommodated in the hollow portion.

具体的には、上流側左右風向板10cは、下流側の一部分が下流側左右風向板10dの中空部に滑動自在に収納されている。なお、その他の構成は上記の実施例と同様である。   Specifically, the upstream left / right wind direction plate 10c is slidably accommodated in a hollow portion of the downstream left / right wind direction plate 10d. Other configurations are the same as those in the above embodiment.

左右への風向制御の際、下流側左右風向板10dは、連結部材6の動作によって、左右方向へと連動する。これにより、下流側左右風向板10dを収納していた上流側左右風向板10cの中空部が、風向下流側へと延出するように構成される。   At the time of controlling the wind direction to the left and right, the downstream left and right wind direction plate 10d is interlocked in the left and right direction by the operation of the connecting member 6. Thereby, the hollow part of the upstream left-right wind direction board 10c which accommodated the downstream left-right wind direction board 10d is comprised so that it may extend to a wind direction downstream side.

このとき、下流側左右風向板10dと上流側左右風向板10cは、完全には離間せず、上流側左右風向板10cの中空部は、下流側左右風向板10dの少なくとも一部を収納した状態を保持可能な範囲で、下流側へと延出する。すなわち、左右風向板10全体は、左右方向への風向制御のときに、風の流れ方向(吹出空気の風向上流から下流の方向)へ左右風向板10を伸長できる構成である。   At this time, the downstream left / right wind direction plate 10c and the upstream left / right wind direction plate 10c are not completely separated, and the hollow portion of the upstream left / right wind direction plate 10c accommodates at least a part of the downstream left / right wind direction plate 10d. Is extended to the downstream side as long as it can be maintained. That is, the entire left and right wind direction plate 10 is configured to extend the left and right wind direction plate 10 in the wind flow direction (downstream direction from the wind improvement flow of the blown air) when the wind direction control in the left and right direction is performed.

次に、左右風向制御から正面風向制御へ移行するときの、左右風向板10の動作を説明する。左右風向制御のとき、上述したように、上流側左右風向板10cの少なくとも一部が、下流側左右風向板10dの中空部に収納された状態を保持可能な範囲で、下流側左右風向板10dが下流側へと延出している。この状態から、連結部材6が左右風向制御のときとは反対方向に動作することで、左右風向板10が左右風向制御から正面風向制御の状態に移行する。このとき、下流側左右風向板10dの下流側へ延出していた中空部分は、次第に上流側左右風向板10cを収納していくように構成される。   Next, the operation of the left and right wind direction plate 10 when shifting from the left and right wind direction control to the front wind direction control will be described. In the left / right wind direction control, as described above, the downstream left / right wind direction plate 10d is within a range in which at least a part of the upstream left / right wind direction plate 10c can be held in the hollow portion of the downstream left / right wind direction plate 10d. Extends downstream. From this state, when the connecting member 6 operates in the opposite direction to that in the left / right wind direction control, the left / right wind direction plate 10 shifts from the left / right wind direction control to the front wind direction control state. At this time, the hollow portion extending to the downstream side of the downstream left / right wind direction plate 10d is configured to gradually accommodate the upstream left / right wind direction plate 10c.

以上の構造とすることで、風向板の寸法,数、及び回転角度によって規定される左右方向への風向制御よりも、広範な風向制御が可能となる。さらに、正面方向への送風時には、左右風向板の流れ方向への長さ寸法を最小とすることで、通風抵抗を低減することができる。   With the above structure, it is possible to control the wind direction in a wider range than the wind direction control in the left-right direction defined by the size and number of the wind direction plates and the rotation angle. Furthermore, when blowing in the front direction, ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates in the flow direction.

次に、本発明に係る第2の実施形態について、図10から図13を用いて説明する。図10は、室内ユニットの側断面図である。図11と図12は、図10に示すC断面を矢印方向から見た図である。すなわち、室内ユニット17の吹出口15における、左右風向板10の配列を示す図である。図11は、吹出空気を室内ユニット17から正面方向へ送風するときの左右風向板10eの位置を示す図である。図12は、吹出空気を室内ユニット17から左方向へ送風するときの左右風向板10eの位置を示す図である。   Next, a second embodiment according to the present invention will be described with reference to FIGS. FIG. 10 is a side sectional view of the indoor unit. 11 and 12 are views of the C cross section shown in FIG. 10 as viewed from the direction of the arrow. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. FIG. 11 is a diagram illustrating the position of the left and right wind direction plates 10e when the blown air is blown from the indoor unit 17 in the front direction. FIG. 12 is a diagram illustrating the position of the left and right wind direction plates 10e when the blown air is blown leftward from the indoor unit 17.

左右風向板10eは、吹出口15の位置に、略水平方向に所定間隔で複数配列している。   A plurality of left and right wind direction plates 10e are arranged at predetermined intervals in the substantially horizontal direction at the position of the air outlet 15.

本実施例の左右風向板10eの上流側の一部は、回転軸13によって背面側のケーシング9に回転自在に軸支される。すなわち、左右風向板10eは、回転軸13を基点として左右方向に回動自在である。また、左右風向板10eは、それぞれ連結部材6で連結されて連動する。また、上下方向へ風向制御を行うとき、上下風向板11は上下に回動する。すなわち、吹出空気は、左右風向板10eと、上下風向板11とによって風向制御されることで、目的とする方向へ送風される。   A part of the upstream side of the right and left wind direction plate 10e of this embodiment is rotatably supported by the casing 9 on the back side by the rotating shaft 13. That is, the left / right airflow direction plate 10e is rotatable in the left / right direction with the rotation shaft 13 as a base point. In addition, the left and right wind direction plates 10e are connected to each other by the connecting member 6 and interlocked. Further, when the wind direction control is performed in the vertical direction, the vertical wind direction plate 11 rotates up and down. That is, the blown air is blown in the target direction by the air direction being controlled by the left and right air direction plates 10e and the up and down air direction plates 11.

正面風向制御(図11)から左右風向制御(図12)に移行するときの、左右風向板10eの動作を説明する。左右方向へ風向制御を行うとき、連結部材6が左右方向,前後方向へ動くことにより、左右風向板10eが連動して、回転軸13を基点に回動する。   The operation of the left and right wind direction plate 10e when shifting from the front wind direction control (FIG. 11) to the left and right wind direction control (FIG. 12) will be described. When the wind direction control is performed in the left-right direction, the connecting member 6 moves in the left-right direction and the front-rear direction, whereby the left-right wind direction plate 10e is interlocked and rotates around the rotation shaft 13.

左右風向板10eは、風向上流から風向下流の方向に伸縮自在な弾性体で構成されており、回転軸13から、連結部材6の連接部までの距離において、風の流れ方向(吹出空気の風向上流から下流の方向)へ伸縮自在である。すなわち、本実施例の左右風向板10eは、一軸方向への弾性を有する材料で構成される。これにより、左右風向板10eは、連結部材6の動作に連動して、流れ方向へと伸縮する。   The left and right wind direction plates 10e are made of an elastic body that can expand and contract in the direction downstream of the wind direction from the wind improving flow, and in the distance from the rotary shaft 13 to the connecting portion of the connecting member 6, the flow direction of the wind (wind direction of the blown air) It can expand and contract in the direction from upstream to downstream. That is, the left and right wind direction plates 10e of the present embodiment are made of a material having elasticity in a uniaxial direction. Thereby, the right and left wind direction plate 10e expands and contracts in the flow direction in conjunction with the operation of the connecting member 6.

次に、左右風向制御(図12)から正面風向制御(図11)へ移行するときの、左右風向板10eの動作を説明する。左右風向制御のとき、上述したように、左右風向板10eが下流側へと伸長している。この状態から、連結部材6が左右風向制御のときとは反対方向に動作することで、左右風向板10eが左右風向制御から正面風向制御の状態に移行する。このとき、左右風向板10eの下流側へ伸長した分は、次第に収縮していくように構成される。   Next, the operation of the left and right wind direction plate 10e when shifting from the left and right wind direction control (FIG. 12) to the front wind direction control (FIG. 11) will be described. In the left / right wind direction control, as described above, the left / right wind direction plate 10e extends to the downstream side. From this state, when the connecting member 6 operates in the opposite direction to that in the left / right wind direction control, the left / right wind direction plate 10e shifts from the left / right wind direction control to the front wind direction control state. At this time, the portion extending toward the downstream side of the left and right wind direction plate 10e is configured to gradually contract.

図13は、室内ユニットの正面側と左側へ風向制御を行うときの、左右風向板10eの動作を示した図である。正面方向送風時の左右風向板10eを実線で示し、左方向送風時の左右風向板10eを破線で示す。左右風向板10eは、最大回転角度αの範囲で、正面方向送風時から左方向送風時の状態に移行する。このとき、左右風向板10eが吹出空気の流れ方向へ伸長する。具体的に、左右風向板10eの風向上流から下流方向における長さ寸法は、正面送風時にbであり、左方向送風時にb′である。そして、b′>bという関係にある。これにより、吹出角度が広角となり、風向板の形状で規定される風向制御範囲よりも、広い範囲へ送風することができる。   FIG. 13 is a diagram illustrating the operation of the left and right wind direction plates 10e when the wind direction is controlled to the front side and the left side of the indoor unit. The left and right wind direction plates 10e when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10e when blowing in the left direction are indicated by broken lines. The left and right airflow direction plate 10e shifts from the front direction air blowing state to the left direction air blowing state within the range of the maximum rotation angle α. At this time, the left and right wind direction plates 10e extend in the flow direction of the blown air. Specifically, the length dimension of the left and right wind direction plates 10e in the downstream direction from the wind improving flow is b when front blowing and b 'when blowing left. The relationship is b ′> b. Thereby, a blowing angle becomes a wide angle and it can blow to the range wider than the wind direction control range prescribed | regulated by the shape of a wind direction board.

一方、左右風向板10eは正面方向送風時に通風抵抗となる。そこで本構成では、左右方向への風向制御を必要としない状態においては、左右風向板10eの寸法bを、左右方向送風時の寸法b′よりも小さくすることにより、通風抵抗を低減できる。さらに、運転による騒音を最小限に抑えることができる。   On the other hand, the left and right wind direction plates 10e provide ventilation resistance when blowing in the front direction. Therefore, in this configuration, in a state where the air direction control in the left and right direction is not required, the ventilation resistance can be reduced by making the dimension b of the left and right air direction plate 10e smaller than the dimension b 'during the air blowing in the left and right direction. Furthermore, noise due to driving can be minimized.

以上の構造とすることで、風向板の寸法,数、及び回転角度によって規定される左右方向への風向制御よりも、広範な風向制御が可能となる。さらに、正面方向への送風時には、左右風向板10eの流れ方向への長さ寸法を最小とすることで、通風抵抗を低減することができる。   With the above structure, it is possible to control the wind direction in a wider range than the wind direction control in the left-right direction defined by the size and number of the wind direction plates and the rotation angle. Furthermore, at the time of blowing in the front direction, ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates 10e in the flow direction.

本発明に係る第3の実施例の空気調和機を、図14から図17を用いて説明する。   An air conditioner according to a third embodiment of the present invention will be described with reference to FIGS.

図14は、室内ユニット17の側断面図である。図15と図16は、図14に示すD断面を矢印方向から見た図である。すなわち、室内ユニット17の吹出口15における、左右風向板10の配列を示す図である。図15と図16における破線で囲んだ部分は、左右風向板10のひとつを拡大した図である。また、図15は、吹出空気を室内ユニット17から正面方向へ送風するときの左右風向板10の位置を示す図である。図16は、吹出空気を室内ユニット17から左方向へ送風するときの左右風向板10の位置を示す図である。   FIG. 14 is a side sectional view of the indoor unit 17. 15 and 16 are views of the D cross section shown in FIG. 14 as viewed from the direction of the arrow. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. 15 and FIG. 16 is an enlarged view of one of the left and right wind direction plates 10. FIG. 15 is a diagram showing the position of the left and right wind direction plates 10 when the blown air is blown from the indoor unit 17 in the front direction. FIG. 16 is a diagram illustrating the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

左右風向板10は、吹出口15の位置に、略水平方向に複数配列している。本実施例の左右風向板10は、吹出空気に対して、上流側左右風向板10fと下流側左右風向板10gとで構成される。また、上下方向へ風向制御を行うとき、上下風向板11は上下に回動する。すなわち、吹出空気は、上流側左右風向板10fと下流側左右風向板10gから構成される左右風向板10と、上下風向板11とによって風向制御されることで、目的とする方向へ送風する。   A plurality of left and right wind direction plates 10 are arranged in a substantially horizontal direction at the position of the air outlet 15. The left and right wind direction plates 10 of the present embodiment are composed of an upstream left and right wind direction plate 10f and a downstream left and right wind direction plate 10g with respect to the blown air. Further, when the wind direction control is performed in the vertical direction, the vertical wind direction plate 11 rotates up and down. That is, the blown air is blown in a target direction by being controlled by the left and right wind direction plates 10 including the upstream left and right wind direction plates 10f and the downstream left and right wind direction plates 10g and the upper and lower wind direction plates 11.

上流側左右風向板10fは、背面側のケーシング9に上流側の一部が固定される。   The upstream left / right airflow direction plate 10f is partially fixed to the casing 9 on the back side.

上流側左右風向板10fは、風向下流側が開口した中空構造を有し、下流側左右風向板10gの一部は、この中空部に収納される。すなわち、本実施例における左右風向板10は、下流側左右風向板10gが、上流側左右風向板10fの中空部内を、風向上流から下流の方向に、滑動自在に構成される。また、下流側左右風向板10gは、吹出口15の略水平方向に配設される棒状の連結部材6で連結される。これにより、下流側左右風向板
10gは、連結部材6の動作に連動する。
The upstream left / right wind direction plate 10f has a hollow structure with an open downstream side in the wind direction, and a part of the downstream left / right wind direction plate 10g is accommodated in the hollow portion. That is, the left and right wind direction plates 10 in this embodiment are configured such that the downstream left and right wind direction plates 10g are slidable in the hollow direction of the upstream left and right wind direction plates 10f in the downstream direction from the wind improving flow. Further, the downstream left and right airflow direction plates 10 g are connected by a rod-like connecting member 6 disposed in a substantially horizontal direction of the air outlet 15. Thereby, the downstream left and right wind direction plates 10 g are interlocked with the operation of the connecting member 6.

正面風向制御(図15)から左右風向制御(図16)に移行するときの、左右風向板10の動作を説明する。左右方向へ風向制御を行うとき、連結部材6が左右方向,前後方向へ動くことにより、下流側左右風向板10gがそれぞれ連動する。上流側左右風向板
10fは固定されているので、連動しない構成である。
The operation of the left and right wind direction plate 10 when shifting from the front wind direction control (FIG. 15) to the left and right wind direction control (FIG. 16) will be described. When the wind direction control is performed in the left-right direction, the connecting member 6 moves in the left-right direction and the front-rear direction, whereby the downstream left-right wind direction plates 10g are interlocked. Since the upstream left and right wind direction plates 10f are fixed, they are not interlocked.

左右への風向制御の際、下流側左右風向板10gは、連結部材6の動作によって、左右方向へと付勢される。これにより、上流側左右風向板10fの中空部に収納されていた下流側左右風向板10gの上流側の一部が、風向下流側へと延出するように構成される。   At the time of the right and left wind direction control, the downstream left and right wind direction plate 10 g is urged in the left and right direction by the operation of the connecting member 6. Accordingly, a part of the upstream side of the downstream left and right wind direction plate 10g housed in the hollow portion of the upstream left and right wind direction plate 10f extends to the downstream side of the wind direction.

このとき、上流側左右風向板10fと下流側左右風向板10gは、完全には離間せず、下流側左右風向板10gの一部は、上流側左右風向板10fの中空部に一部が収納された状態を保持できる範囲で、下流側へと延出する。すなわち、左右風向板10全体は、左右方向への風向制御のときに、風の流れ方向(風向上流から下流の方向)へ伸長できる構成である。また、下流側左右風向板10gは、弾性体で構成されており、左右方向への風向制御のとき、送風方向へ湾曲する。また、上流側左右風向板10fは、特に弾性を有することで湾曲させるものではない。すなわち、上流側左右風向板10fは湾曲せず、下流側左右風向板10gは湾曲する構成である。   At this time, the upstream left and right wind direction plates 10f and the downstream left and right wind direction plates 10g are not completely separated from each other, and a part of the downstream left and right wind direction plates 10g is partially stored in the hollow portion of the upstream left and right wind direction plate 10f. It extends to the downstream side as long as it can hold the state. That is, the entire left and right wind direction plate 10 is configured to be able to extend in the wind flow direction (downstream direction from the wind improving flow) when controlling the wind direction in the left and right direction. Further, the downstream left and right wind direction plates 10g are made of an elastic body, and are curved in the blowing direction when controlling the wind direction in the left and right direction. Further, the upstream left / right airflow direction plate 10f is not particularly curved because it has elasticity. That is, the upstream left and right wind direction plates 10f are not curved, and the downstream left and right wind direction plate 10g is curved.

次に、左右風向制御(図16)から正面風向制御(図15)へ移行するときの、左右風向板10の動作を説明する。左右風向制御のとき、上述したように、下流側左右風向板10gの少なくとも一部が、上流側左右風向板10fの中空部に収納された状態を保持可能な範囲で、下流側左右風向板10gが風向下流側へと湾曲しながら延出している。この状態から、連結部材6が左右風向制御のときとは反対方向に動作することで、左右風向板10が左右風向制御の状態から正面風向制御の状態に移行する。このとき、下流側左右風向板10gは、湾曲した状態から直線の状態へと戻る。これに伴い、下流側左右風向板10gにおける下流側へ延出した部分は、次第に上流側左右風向板10fの中空部に滑動して収納される。   Next, the operation of the left and right wind direction plate 10 when shifting from the left and right wind direction control (FIG. 16) to the front wind direction control (FIG. 15) will be described. In the left / right wind direction control, as described above, the downstream left / right wind direction plate 10g is within a range in which at least a part of the downstream left / right wind direction plate 10g can be held in the hollow portion of the upstream left / right wind direction plate 10f. Extends while curving toward the downstream side of the wind direction. From this state, when the connecting member 6 operates in the direction opposite to that in the left / right wind direction control, the left / right wind direction plate 10 shifts from the left / right wind direction control state to the front wind direction control state. At this time, the downstream left and right wind direction plates 10g return from the curved state to the straight state. Accordingly, the portion of the downstream left and right wind direction plate 10g extending downstream is gradually slid and stored in the hollow portion of the upstream left and right wind direction plate 10f.

図17は、室内ユニットの正面方向と左方向へ風向制御を行うときの、左右風向板10の動作を示した図である。正面方向送風時の左右風向板10を実線で示し、左方向送風時の左右風向板10を破線で示す。   FIG. 17 is a diagram illustrating the operation of the left and right wind direction plates 10 when the wind direction control is performed in the front direction and the left direction of the indoor unit. The left and right wind direction plates 10 when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10 when blowing in the left direction are indicated by broken lines.

左方向への風向制御は、下流側左右風向板10gが上流側左右風向板10fの中空部を滑動することにより、左右風向板10全体が風の流れ方向へ伸長する。   In the leftward wind direction control, the downstream left and right wind direction plates 10g slide in the hollow portion of the upstream left and right wind direction plate 10f, so that the entire left and right wind direction plates 10 extend in the wind flow direction.

また、下流側左右風向板10gは、弾性を有しているので、左右風向制御のときに湾曲した形状となる。この構成により、送風ファン8から送られた吹出空気は、上流側左右風向板10fの位置では、そのまま略正面方向に送風され、下流側左右風向板10gの位置では、次第に目的とする送風方向へと曲線状に偏向されて送風される。   Further, since the downstream left / right wind direction plate 10g has elasticity, it has a curved shape when the left / right wind direction control is performed. With this configuration, the blown air sent from the blower fan 8 is blown substantially in the front direction at the position of the upstream left and right wind direction plates 10f, and gradually toward the target blowing direction at the position of the downstream left and right wind direction plates 10g. The air is deflected in a curved line.

すなわち、吹出空気は、左右風向板10の上流側から下流側の方向に、曲線状の流線が形成され、スムーズに偏向して送風することができる。   That is, the blown air has a curved streamline formed in the direction from the upstream side to the downstream side of the left and right wind direction plates 10 and can be smoothly deflected and blown.

左右方向へ風向制御される吹出空気は、左右風向板10が流れ方向への長さ寸法が長くなることで、吹出角度が広角となる。これにより、風向板の形状で規定される風向制御範囲よりも、広い範囲へ送風することができる。   The blown air whose wind direction is controlled in the left-right direction has a wide blowing angle as the length of the left-right wind direction plate 10 in the flow direction becomes longer. Thereby, it can blow to the range wider than the wind direction control range prescribed | regulated by the shape of a wind direction board.

一方、左右風向板10は正面方向送風時に通風抵抗となる。すなわち、本実施例では、左右方向への風向制御を必要としない状態においては、左右風向板10の流れ方向への長さ寸法を左右風向制御のときよりも小さくすることにより、通風抵抗を低減できる。さらに、運転による騒音を最小限に抑えることができる。   On the other hand, the left and right wind direction plates 10 provide ventilation resistance when blowing in the front direction. That is, in this embodiment, in a state where the air direction control in the left-right direction is not required, the ventilation resistance is reduced by making the length dimension in the flow direction of the left-right air direction plate 10 smaller than that in the left-right air direction control. it can. Furthermore, noise due to driving can be minimized.

以上の構造とすることで、左右風向板10の寸法,数、及び回転角度によって規定される左右方向への風向制御よりも、広範な風向制御が可能となる。さらに、正面方向への送風時には、左右風向板の流れ方向への長さ寸法を最小とすることで、通風抵抗を低減することができる。さらに、上流側左右風向板10fはケーシング9に固定されているため、左右風向板への風の流入を良好にでき、左右方向へ風向制御を行う場合に、騒音を低減することができる。   With the above structure, it is possible to control the wind direction in a wider range than the wind direction control in the left and right direction defined by the size and number of the left and right wind direction plates 10 and the rotation angle. Furthermore, when blowing in the front direction, ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates in the flow direction. Furthermore, since the upstream left and right wind direction plates 10f are fixed to the casing 9, the flow of wind into the left and right wind direction plates can be improved, and noise can be reduced when the wind direction control is performed in the left and right directions.

本実施例は、下流側左右風向板10gが上流側左右風向板10fの中空部に収納される構成である。しかし、これに限られるものではなく、別の構成について図18から図21を用いて説明する。   In this embodiment, the downstream left / right wind direction plate 10g is housed in the hollow portion of the upstream left / right wind direction plate 10f. However, the present invention is not limited to this, and another configuration will be described with reference to FIGS.

図18は、室内ユニット17の側断面図を示している。図19と図20は、図18に示すD断面を、矢印方向から見た図である。すなわち、室内ユニット17の吹出口15における、左右風向板10の配列を示す図である。図19と図20における破線で囲んだ部分は、左右風向板10のひとつを拡大した図である。また、図19は、吹出空気を室内ユニット17から正面方向に送風するときの左右風向板10の位置を示す図である。図20は、吹出空気を室内ユニット17から左方向へ送風するときの左右風向板10の位置を示す図である。   FIG. 18 is a side sectional view of the indoor unit 17. 19 and 20 are views of the D cross section shown in FIG. 18 as viewed from the direction of the arrows. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. A portion surrounded by a broken line in FIGS. 19 and 20 is an enlarged view of one of the left and right wind direction plates 10. Moreover, FIG. 19 is a figure which shows the position of the left-right wind direction board 10 when blowing air is blown in the front direction from the indoor unit 17. FIG. FIG. 20 is a diagram illustrating the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

図21は、室内ユニット17の正面方向と左方向へ風向制御を行うときの、左右風向板10の動作を示した図である。正面方向送風時の左右風向板10を実線で示し、左方向送風時の左右風向板10を破線で示す。   FIG. 21 is a diagram illustrating the operation of the left and right wind direction plates 10 when the wind direction control is performed in the front direction and the left direction of the indoor unit 17. The left and right wind direction plates 10 when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10 when blowing in the left direction are indicated by broken lines.

上記の構成と異なる点は、下流側左右風向板10iに風向上流側が開口した中空部が設けられ、この中空部に上流側左右風向板10hの下流側の一部が収納されている点である。   The difference from the above configuration is that the downstream left and right wind direction plate 10i is provided with a hollow portion with an open wind improving flow side, and a part of the downstream side of the upstream left and right wind direction plate 10h is accommodated in this hollow portion. .

具体的には、上流側左右風向板10hの下流側の一部分が下流側左右風向板10iの中空部に滑動自在に収納されている。   Specifically, a part of the downstream side of the upstream left / right wind direction plate 10h is slidably accommodated in the hollow portion of the downstream left / right wind direction plate 10i.

左右への風向制御の際、下流側左右風向板10iは、連結部材6の動作によって、左右方向へと連動する。これにより、上流側左右風向板10hを収納していた下流側左右風向板10iの中空部が、風向下流側へと延出するように構成される。   During the control of the wind direction to the left and right, the downstream left and right wind direction plate 10 i is interlocked in the left and right direction by the operation of the connecting member 6. Thereby, the hollow part of the downstream left-right wind direction board 10i which accommodated the upstream left-right wind direction board 10h is comprised so that it may extend to a wind direction downstream side.

このとき、上流側左右風向板10hと下流側左右風向板10iは、完全には離間せず、下流側左右風向板10iの中空部は、上流側左右風向板10hの一部を収納した状態を保持できる範囲で、下流側へと延出する。すなわち、左右風向板10全体は、左右方向への風向制御のときに、風の流れ方向(吹出空気の風向上流から下流の方向)へ左右風向板10を伸長できる構成である。   At this time, the upstream left and right wind direction plates 10h and the downstream left and right wind direction plates 10i are not completely separated from each other, and the hollow portion of the downstream left and right wind direction plate 10i is in a state in which a part of the upstream left and right wind direction plates 10h is accommodated. Extends downstream as long as it can be retained. That is, the entire left and right wind direction plate 10 is configured to extend the left and right wind direction plate 10 in the wind flow direction (downstream direction from the wind improvement flow of the blown air) when the wind direction control in the left and right direction is performed.

また、上流側左右風向板10hは、弾性を有しているので、左右風向制御のときに湾曲した形状となる。また、下流側左右風向板10iは、特に弾性を有することで湾曲させるものではない。すなわち、下流側左右風向板10iは湾曲せず、上流側左右風向板10hは湾曲する構成である。この構成により、送風ファン8から送られた正面方向の風向を持つ吹出空気は、上流側左右風向板10hでは、目的とする送風方向へと曲線状に次第に偏向されて送風される。   Further, since the upstream left / right wind direction plate 10h has elasticity, it has a curved shape when the left / right wind direction control is performed. Further, the downstream left and right wind direction plates 10i are not particularly curved because they have elasticity. That is, the downstream left / right wind direction plate 10i is not curved, and the upstream left / right wind direction plate 10h is curved. With this configuration, the blown air having a wind direction in the front direction sent from the blower fan 8 is gradually deflected in a curved shape toward the target blowing direction and is blown by the upstream left and right wind direction plates 10h.

すなわち、吹出空気は、左右風向板10の上流側から下流側の方向に、曲線状の流線が形成され、スムーズに偏向して送風することができる。   That is, the blown air has a curved streamline formed in the direction from the upstream side to the downstream side of the left and right wind direction plates 10 and can be smoothly deflected and blown.

以上の構造とすることで、風向板の寸法,数、及び回転角度によって規定される左右方向への風向制御よりも、広範な風向制御が可能となる。さらに、正面方向への送風時には、左右風向板の流れ方向への長さ寸法を最小とすることで、通風抵抗を低減することができる。さらに、上流側左右風向板10hはケーシング9に固定されているため、左右風向板への風の流入を良好にでき、左右方向へ風向制御を行う場合に、騒音を低減することができる。   With the above structure, it is possible to control the wind direction in a wider range than the wind direction control in the left-right direction defined by the size and number of the wind direction plates and the rotation angle. Furthermore, when blowing in the front direction, ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates in the flow direction. Furthermore, since the upstream left and right wind direction plates 10h are fixed to the casing 9, the flow of wind into the left and right wind direction plates can be improved, and noise can be reduced when the wind direction control is performed in the left and right directions.

本発明に係る第4の実施形態を、図22〜図25を用いて説明する。   A fourth embodiment according to the present invention will be described with reference to FIGS.

図22は、室内ユニットの側断面図である。図23と図24は、図22に示すE断面を矢印方向から見た図である。すなわち、室内ユニット17の吹出口15における、左右風向板10の配列を示す図である。また、図23は、吹出空気を室内ユニット17から正面方向へ送風するときの左右風向板10の位置を示す図である。図24は、吹出空気を室内ユニット17から左方向へ送風するときの左右風向板10の位置を示す図である。   FIG. 22 is a side sectional view of the indoor unit. 23 and 24 are views of the E cross section shown in FIG. 22 as viewed from the direction of the arrows. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. Moreover, FIG. 23 is a figure which shows the position of the left-right wind direction board 10 when blowing air is blown in the front direction from the indoor unit 17. FIG. FIG. 24 is a diagram illustrating the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

左右風向板10は、吹出口15の位置に、略水平方向に複数配列している。本実施例の左右風向板10jの上流側の一部は、背面側のケーシング9に固定される。また、左右風向板10jは、それぞれ連結部材6で連結されているので、左右風向板10jは連動できる。また、上下方向へ風向制御を行うとき、上下風向板11は上下に回動する。すなわち、室内ユニット17の吹出口15から吹出される空気は、左右風向板10jと、上下風向板11とによって風向制御されることで、目的とする方向へ送風される。   A plurality of left and right wind direction plates 10 are arranged in a substantially horizontal direction at the position of the air outlet 15. A part of the upstream side of the left and right wind direction plate 10j of the present embodiment is fixed to the casing 9 on the back side. Further, since the left and right wind direction plates 10j are respectively connected by the connecting members 6, the left and right wind direction plates 10j can be interlocked. Further, when the wind direction control is performed in the vertical direction, the vertical wind direction plate 11 rotates up and down. That is, the air blown from the blowout port 15 of the indoor unit 17 is blown in the intended direction by the airflow direction being controlled by the left and right airflow direction plates 10j and the vertical airflow direction plate 11.

正面風向制御(図23)から左右風向制御(図24)に移行するときの、左右風向板10の動作を説明する。左右風向制御を行うとき、連結部材6が左右方向,前後方向へ動くことにより、左右風向板10jが連動する。左右風向板10jは、弾性部材から構成されており、上流側の一部が固定されているので、連結部材6に連動して湾曲する。すなわち、左右風向板10jは、固定端から、連結部材6の連接部までの距離において、風の流れ方向(風向上流から下流の方向)へ曲線状の流線を形成する。   The operation of the left and right wind direction plate 10 when shifting from the front wind direction control (FIG. 23) to the left and right wind direction control (FIG. 24) will be described. When the left / right wind direction control is performed, the connecting member 6 moves in the left / right direction and the front / rear direction, whereby the left / right wind direction plate 10j is interlocked. Since the left and right wind direction plates 10j are made of an elastic member and a part of the upstream side is fixed, the left and right wind direction plates 10j are curved in conjunction with the connecting member 6. That is, the left and right wind direction plates 10j form curved streamlines in the wind flow direction (downstream direction from the wind improving flow) at a distance from the fixed end to the connecting portion of the connecting member 6.

次に、左右風向制御(図24)から正面風向制御(図23)に移行するときの、左右風向板10jの動作を説明する。左右風向制御のとき、前述したように、左右風向板10jは、連結部材6に連動して湾曲している。この状態から、連結部材6が左右風向制御のときとは反対方向に動作することで、左右風向板10jが左右風向制御から正面風向制御の状態に移行する。このとき、左右風向板10jの形状は、湾曲した状態から次第に直線状になる。   Next, the operation of the left / right wind direction plate 10j when shifting from the left / right wind direction control (FIG. 24) to the front wind direction control (FIG. 23) will be described. In the left / right wind direction control, the left / right wind direction plate 10j is curved in conjunction with the connecting member 6 as described above. From this state, when the connecting member 6 operates in the opposite direction to that in the left / right wind direction control, the left / right wind direction plate 10j shifts from the left / right wind direction control to the front wind direction control state. At this time, the shape of the left and right wind direction plates 10j gradually becomes linear from the curved state.

図25は、室内ユニットの正面方向と左方向へ風向制御を行うときの、左右風向板10jの動作を示した図である。正面方向送風時の左右風向板10jを実線で示し、左方向送風時の左右風向板10jを破線で示す。図25に示すように、左側への風向制御時は、正面送風時に比べて、左右風向板10jが風の流れ方向へ伸長して、曲線状に変形する。   FIG. 25 is a diagram illustrating the operation of the left and right wind direction plates 10j when the wind direction control is performed in the front direction and the left direction of the indoor unit. The left and right wind direction plates 10j when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10j when blowing in the left direction are indicated by broken lines. As shown in FIG. 25, when the airflow direction is controlled to the left, the left and right airflow direction plates 10j extend in the flow direction of the wind and are deformed in a curved shape as compared with the front air blowing.

すなわち、吹出空気は、左右風向板10jの上流側から下流側の方向に、曲線状の流線が形成されるので、スムーズに偏向して送風することができる。   That is, since the curved streamlines are formed in the direction from the upstream side to the downstream side of the left and right wind direction plates 10j, the blown air can be smoothly deflected and blown.

左右方向へ風向制御される吹出空気は、左右風向板10jが送風方向への長さ寸法が長くなることで、吹出角度が広角となる。これにより、風向板の形状で規定される風向制御範囲よりも、広い範囲へ送風することができる。   The blown air whose wind direction is controlled in the left-right direction has a wide blowing angle as the length of the left-right wind direction plate 10j in the blowing direction becomes longer. Thereby, it can blow to the range wider than the wind direction control range prescribed | regulated by the shape of a wind direction board.

一方、左右風向板10jは正面方向送風時に通風抵抗となる。そこで本構成では、左右風向板10jの送風方向への長さ寸法を、左右方向送風時よりも正面方向送風時に小さくすることにより、通風抵抗を低減できる。さらに、正面方向への送風時は、左右風向板10jの流れ方向への長さ寸法は小さいので、運転による騒音を最小限に抑えることができる。   On the other hand, the left and right wind direction plates 10j provide ventilation resistance when blowing in the front direction. Therefore, in this configuration, the ventilation resistance can be reduced by making the length of the left and right wind direction plates 10j in the blowing direction smaller when blowing in the front direction than when blowing in the left and right direction. Furthermore, since the length in the flow direction of the left and right wind direction plates 10j is small when blowing in the front direction, noise due to operation can be minimized.

以上の構成により、左右風向板10jの寸法,数、及び回転角度によって規定される左右方向への風向制御よりも、広範な風向制御が可能となる。さらに、正面方向への送風時には、左右風向板10jの流れ方向への長さ寸法を最小とすることで、通風抵抗を低減することができる。さらに、左右風向板10jは、ケーシング9に固定されているため、左右風向板10jへの風の流入を良好にでき、左右方向へ風向制御を行う場合に、騒音を低減することができる。   With the above configuration, a wider range of wind direction control is possible than the wind direction control in the left-right direction defined by the size, number, and rotation angle of the left-right wind direction plate 10j. Furthermore, at the time of blowing in the front direction, the ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates 10j in the flow direction. Further, since the left and right wind direction plates 10j are fixed to the casing 9, the flow of wind into the left and right wind direction plates 10j can be improved, and noise can be reduced when the wind direction control is performed in the left and right directions.

以上の実施例は、左右風向板を連動させる連結部材6を駆動装置によって動作させる構成である。この構成に限らず、左右風向板のひとつが駆動装置によって動作するように構成してもよい。この場合、左右風向板同士は連結部材で連結されているので、駆動装置に連結された左右風向板の動作に伴って、左右風向板全体を連動させることができる。   In the above embodiment, the connecting member 6 that interlocks the right and left wind direction plates is operated by the driving device. Not limited to this configuration, one of the left and right wind direction plates may be configured to be operated by a driving device. In this case, since the left and right wind direction plates are connected by the connecting member, the entire left and right wind direction plates can be interlocked with the operation of the left and right wind direction plates connected to the driving device.

また、連結部材で全ての左右風向板を連結せずに、所定数ごとの左右風向板が連動するように連結する構成であってもよい。一例として、吹出口15の水平方向に対して左側と右側で独立して左右風向板が動作するように連結する構成がある。   Moreover, the structure connected not to connect all the right and left wind direction plates with a connection member so that every predetermined number of right and left wind direction plates may interlock | cooperate may be sufficient. As an example, there is a configuration in which the left and right wind direction plates are connected to operate independently on the left side and the right side with respect to the horizontal direction of the air outlet 15.

上記実施例の左右風向板を備えた空気調和機は、正面方向送風時の通風抵抗を低減し、かつ、左右方向へ広角に調和空気を送風できる。これにより、室内ユニットの設置状況によらず、室内の隅々に調和空気を送風することができる。すなわち、室内ユニットを設置した部屋の間取りによらず、室内の温度むらを低減することができる。   The air conditioner provided with the left and right wind direction plates of the above embodiment can reduce the ventilation resistance when blowing in the front direction and can blow conditioned air in a wide angle in the left and right direction. Thereby, conditioned air can be blown to every corner of the room regardless of the installation status of the indoor unit. That is, the temperature unevenness in the room can be reduced regardless of the room layout in which the indoor unit is installed.

また、送風騒音を低減できるので、設置した室内環境の静穏性を向上できる。   Moreover, since ventilation noise can be reduced, the quietness of the installed indoor environment can be improved.
