Description

本発明は空気調和機の室内機、特に、調和空気の吹出方向を案内する風向板が設置された空気調和機の室内機に関するものである。   The present invention relates to an indoor unit of an air conditioner, and more particularly to an indoor unit of an air conditioner provided with a wind direction plate that guides the blowing direction of conditioned air.

従来、空気調和機の室内機(以下、単に「室内機」と称す)、特に、壁面等に設置される室内機は、吹出風路に設置された調和空気の吹出方向を左右に案内する左右風向板(左右風向変更羽根に同じ)と、吹出口(吹出風路の終端に同じ)に設置された調和空気の吹出方向を上下に案内する上下風向板(上下風向変更羽根に同じ、以下、「上下風向板」と称す)が設置されている。
そして、上下風向板を回転させる機構として、上下風向板の回転軸を左右方向(上下方向に垂直な方向)に配置して、その回転軸に電動モーターの回転軸を直接接続した発明が開示されている(例えば、特許文献1参照)。
また、上下風向板を回転させる機構として、上下風向板の回転軸を左右方向に配置して、その回転軸と電動モーターの回転軸とをリンク機構によって連結する発明が開示されている(例えば、特許文献2参照)。
Conventionally, an indoor unit of an air conditioner (hereinafter simply referred to as an “indoor unit”), particularly an indoor unit installed on a wall surface or the like, has a right and left guide to the left and right of the conditioned air blowing direction installed in the blowing air channel. A wind direction plate (same as the left and right wind direction change blades) and an up and down wind direction plate (same as the up and down wind direction change blades) that guide the up and down direction of the conditioned air installed at the outlet (same as the end of the blowout air path), It is called “up and down wind direction board”.
Then, as a mechanism for rotating the up / down wind direction plate, an invention is disclosed in which the rotation axis of the up / down wind direction plate is arranged in the left / right direction (direction perpendicular to the up / down direction) and the rotation shaft of the electric motor is directly connected to the rotation shaft. (For example, refer to Patent Document 1).
Further, as a mechanism for rotating the vertical wind direction plate, an invention has been disclosed in which the rotary shaft of the vertical wind direction plate is arranged in the left-right direction and the rotary shaft and the rotary shaft of the electric motor are connected by a link mechanism (for example, Patent Document 2).

特開昭61−289259号公報(第3頁、第2図)JP-A-61-289259 (page 3, FIG. 2) 特開2007−155186号公報(第3頁、第2図)JP 2007-155186 A (page 3, FIG. 2)

特許文献1に開示された発明は、上下風向板の羽根部分の左右方向の一方の端面に回転軸を設置し、かかる回転軸に電動モーターの回転軸を接続している。また、吹出口に至る風路の左右は対向した一対の風路側壁によって形成され、風路側壁と室内機を形成する筐体の側面(以下、「筐体側面」と称す)との間には、所定のスペースが形成され、かかるスペースに電動モーターが配置されている。
そして、上下風向板が回転すると、羽根部分が風路(風路側壁に挟まれた範囲)の一部に侵入する。すなわち、上下風向板の左右方向の長さは、吹出口の左右方向の長さ(風路側壁同士の間隔に同じ)よりも短くなっている。
In the invention disclosed in Patent Document 1, a rotating shaft is installed on one end face in the left-right direction of the blade portion of the up-and-down wind direction plate, and the rotating shaft of the electric motor is connected to the rotating shaft. In addition, the left and right sides of the air passage leading to the air outlet are formed by a pair of opposing air passage side walls, and between the air passage side wall and the side surface of the casing forming the indoor unit (hereinafter referred to as “housing side face”). A predetermined space is formed, and an electric motor is disposed in the space.
And if an up-and-down wind direction board rotates, a blade | wing part will penetrate | invade into a part of wind path (range sandwiched by the wind path side wall). That is, the length in the left-right direction of the vertical wind direction plate is shorter than the length in the left-right direction of the air outlet (same as the interval between the air passage side walls).

(あ)このため、上下風向板と風路側壁との間に隙間が生じるため、運転停止時に、吹出口が完全に閉塞されない印象を与え、意匠性を損なう一因になるという問題があった。
(い)また、調和空気を左右方向の広い範囲(斜め外側)に吹き出させるために、風路側壁の所定範囲を筐体側面に向かって折り曲げて、テーパー状範囲(一対の風路側壁においてはハ字状を呈する)を形成したいところ、かかるテーパー状範囲が露出するため、意匠性が阻害され、かかるテーパー状範囲を設けることができなかった。このため、調和空気の左右方向の吹出範囲が抑えられるという問題があった。
(う)一方、仮に、意匠性を犠牲にして、テーパー状範囲を設けたとしても、テーパー状範囲には羽根部分が存在しないため、テーパー状範囲を通過した調和空気は吹出方向が上下に案内されないという問題があった。
(A) For this reason, since a gap is generated between the vertical wind direction plate and the air passage side wall, there is a problem that when the operation is stopped, an impression that the air outlet is not completely blocked is given, and the design is impaired. .
(Ii) In order to blow out conditioned air in a wide range (diagonally outside) in the left-right direction, a predetermined range of the air channel side wall is bent toward the side of the housing, and a tapered range (in the pair of air channel side walls) Where the taper-shaped range is to be formed, the taper-shaped range is exposed, so that the design is hindered, and the taper-shaped range cannot be provided. For this reason, there existed a problem that the blowing range of the left-right direction of conditioned air was suppressed.
(U) On the other hand, even if a tapered range is provided at the expense of design, since there are no blade portions in the tapered range, the conditioned air that has passed through the tapered range is guided upward and downward. There was a problem of not being.

特許文献2に開示された発明は、特許文献1に開示された発明と同様に、上下風向板が回転すると、羽根部分が吹出口(風路側壁に挟まれた範囲)の一部に侵入するものであるため、前記問題(あ)があった。
(え)また、リンク機構は風路側壁と筐体側面との間に収納するものである。そのため、リンク機構を左右方向で薄く形成することによって、風路側壁を筐体側面に近づけることができるものの、電動モーターを風路に突出させないためには、かえって風路側壁と筐体側面とを離す必要があったり、電動モーターと室内機の構成部材(例えば、ドレン水を排出するドレンホースの接続部等)とが干渉しないようにするためには、筐体の奥行きを拡大したりする必要があった。このため、筐体の小型化が困難になるという問題があった。
In the invention disclosed in Patent Document 2, as in the invention disclosed in Patent Document 1, when the up-and-down wind direction plate rotates, the blade portion enters a part of the outlet (a range sandwiched between the air passage side walls). Therefore, there was the problem (a).
(E) Moreover, a link mechanism is accommodated between an air channel side wall and a housing | casing side surface. Therefore, by forming the link mechanism thin in the left-right direction, the air passage side wall can be brought closer to the side surface of the housing.However, in order to prevent the electric motor from protruding into the air passage, the air passage side wall and the housing side surface are It is necessary to increase the depth of the housing in order to prevent separation between the electric motor and the components of the indoor unit (for example, the drain hose connection part that drains the drain water). was there. For this reason, there existed a problem that size reduction of a housing | casing became difficult.

この発明は、上記のような問題を解決するためになされたもので、第1の目的は、運転停止時に、上下風向板と風路側壁との間に隙間が生じないようにして、意匠性を担保することができる室内機を得るものである(第1の目的)。
また、調和空気の左右方向の吹出範囲を拡大しながらも、上下方向の吹出方向を案内することができる室内機を得るものである(第2の目的)。
さらに、室内機の構成部材と干渉しない構成によって、筐体の小型化を可能にする室内機を得るものである(第3の目的)。
The present invention has been made to solve the above-described problems. The first object of the present invention is to provide a design property that prevents a gap from being generated between the vertical airflow direction plate and the airway side wall when the operation is stopped. (1st purpose) is obtained.
In addition, the present invention provides an indoor unit capable of guiding the vertical blowing direction while expanding the horizontal range of the conditioned air (second purpose).
Furthermore, an indoor unit that can reduce the size of the housing is obtained by a configuration that does not interfere with the constituent members of the indoor unit (third object).

(i)本発明は、風路側壁と筐体側面との間に形成されたモーター収納庫がモーター覆い板によって覆われ、上下前風向板および上下後風向板が回転された際(例えば、空気調和機が運転停止している間)、羽根部分の左右方向の端部分および羽根部分の左右方向の端部分が、それぞれモーター覆い板に略平行に対峙する。したがって、風路側壁と筐体側面との隙間が視認不能に覆われるから、室外機の意匠性が担保される。
(ii)また、モーター覆い板にスリット状のモーター覆い板前切欠部およびモーター覆い板後切欠部が形成され、これらにそれぞれ連通したスリット状の風路側壁前切欠部および風路側壁後切欠部が風路側壁に形成されたことによって、回転する上下前風向板および上下後風向板を何れも略矩状にすることが可能になっている。そして、上下前風向板および上下後風向板の左右方向の長さが、吹出口の左右方向の幅(風路側壁同士の距離に同じ)よりも大きいから、吹出口から吹き出された調和空気は上下方向に確実に案内される。よって、快適性が向上する。

(I) In the present invention, when the motor storage formed between the air passage side wall and the side surface of the casing is covered with the motor cover plate, and the up / down front wind direction plate and the up / down rear wind direction plate are rotated (for example, air While the conditioner is stopped), the left and right end portions of the blade portion and the left and right end portions of the blade portion face each other substantially parallel to the motor cover plate. Therefore, since the gap between the air channel side wall and the side surface of the housing is covered in an invisible manner, the design of the outdoor unit is ensured.
(Ii) A slit-like motor cover plate front notch and a motor cover plate rear notch are formed on the motor cover plate, and a slit-like air channel side wall front notch portion and air path side wall rear notch portion respectively communicated with the motor cover plate. By being formed on the air channel side wall, the rotating front and rear wind direction plates and the upper and lower rear wind direction plates can both be substantially rectangular. And since the length in the left-right direction of the up-and-down front wind direction plate and the up-and-down rear wind direction plate is larger than the width in the left-right direction of the air outlet (the same as the distance between the air passage side walls), the conditioned air blown out from the air outlet is It is reliably guided in the vertical direction. Therefore, comfort is improved.
(Iii) Not only when blowing forward (in a direction perpendicular to the left-right direction) but also when blowing to the “slanting outside” that is greatly inclined in the left-right direction from the blow-out port, the wind direction up and down also in the diagonally outward direction of the blow-out port Since the end portions of the plate and the up / down rear wind direction plate exist, the conditioned air blown out is also guided in the up / down direction. Therefore, comfort is improved.
(Iv) Further, without changing the arrangement of the motor storage or the front / rear drive motor and the rear / rear drive motor, the front / rear wind direction plate and the front / rear wind direction plate are expanded (the length in the left-right direction is larger than the width of the outlet). Long), there is no need to enlarge the housing.

図1の運転停止時において、吹出口17の略全域が上下前風向板50L、50Rおよび上下後風向板60L、60Rによって覆われている。すなわち、上下前風向板50L、50R(以下、まとめて「上下前風向板50」と称す)の前面側の側縁は筐体前面14の下面側の側縁に重なるように当接または近接し、意匠パネル19に滑らかに繋がる曲面を形成している。また、上下後風向板60L、60R(以下、まとめて「上下後風向板60」と称す)の前面側の側縁は上下前風向板50の下面側の側縁に重なるように当接または近接している。
(When operation is stopped)
When the operation is stopped in FIG. 1, substantially the entire area of the air outlet 17 is covered with the upper and lower front wind direction plates 50L and 50R and the upper and lower rear wind direction plates 60L and 60R. That is, the side edges on the front side of the upper and lower front wind direction plates 50L and 50R (hereinafter collectively referred to as “up and down front wind direction plates 50”) are in contact with or close to the side edge on the lower surface side of the front surface 14 of the housing. A curved surface smoothly connected to the design panel 19 is formed. Further, the front side edges of the upper and lower rear wind direction plates 60L and 60R (hereinafter collectively referred to as “upper and lower rear wind direction plates 60”) are in contact with or close to the lower side edge of the upper and lower front wind direction plate 50. is doing.

さらに、上下前風向板50Lの一方の羽根端部52Lおよび上下後風向板60Lの一方の羽根端部62Lは筐体側面15Lに近づき、一方の羽根端部52Lからの所定範囲および一方の羽根端部62Lからの所定範囲が、一方のモーター覆い板80Lおよびモーター覆い板面取り部分83Lを覆っている。
同様に、吹出口17の右側においても、上下前風向板50Rの他方の羽根端部52Rおよび上下後風向板60Rの他方の羽根端部62Rは筐体側面15Rに近づき、他方の羽根端部52Rからの所定範囲および他方の羽根端部62Rからの所定範囲が、他方のモーター覆い板80Rおよびモーター覆い板面取り部分83Rを覆っている(何れも図示しない)。
Furthermore, one blade end portion 52L of the up / down front wind direction plate 50L and one blade end portion 62L of the up / down rear wind direction plate 60L approach the housing side surface 15L, and a predetermined range from the one blade end portion 52L and one blade end. A predetermined range from the portion 62L covers one motor cover plate 80L and the motor cover plate chamfered portion 83L.
Similarly, also on the right side of the air outlet 17, the other blade end portion 52R of the up / down front wind direction plate 50R and the other blade end portion 62R of the up / down rear wind direction plate 60R approach the casing side surface 15R, and the other blade end portion 52R. And a predetermined range from the other blade end portion 62R cover the other motor cover plate 80R and the motor cover plate chamfered portion 83R (both not shown).

したがって、上下前風向板50Lの羽根端部52Lと風路側壁70Lとの間、上下後風向板60Lの羽根端部62Lと風路側壁70Lとの間に、隙間が形成されないから、美観が保たれ、意匠性に優れている。
同様に、吹出口17の右側でも、上下前風向板50Rの羽根端部52Rと風路側壁70R(図示しない)との間、上下後風向板60Rの羽根端部62Rと風路側壁70R(図示しない)との間に、隙間が形成されないから、美観が保たれ、意匠性に優れている。
なお、上下後風向板60の後面側の側縁と、筐体底面13との間に隙間が形成されているが、筐体後面12に近い位置であるため、該隙間が意匠性を阻害することはない。
Therefore, since no gap is formed between the blade end portion 52L of the up / down front wind direction plate 50L and the air passage side wall 70L and between the blade end portion 62L of the up / down air direction plate 60L and the air passage side wall 70L, the aesthetic appearance is maintained. It has excellent design.
Similarly, on the right side of the air outlet 17, between the blade end portion 52R of the up / down front wind direction plate 50R and the air passage side wall 70R (not shown), the blade end portion 62R of the up / down rear air direction plate 60R and the air passage side wall 70R (shown). Since no gap is formed, the aesthetics are maintained and the design is excellent.
In addition, although the clearance gap is formed between the side edge of the rear surface side of the up-and-down rear wind direction board 60, and the housing | casing bottom surface 13, since it is a position near the housing | casing rear surface 12, this clearance gap impairs design property. There is nothing.

(運転時)
このように構成された空気調和機の室内機100において、運転指令が投入されると、送風ファン30の回転によって吸込口16から吸い込まれた室内空気はフィルター18で除塵され熱交換器20で冷風または温風に変わり、吹出風路33を経由して、吹出口17から吹き出される。その際、左右風向板40L、40R(以下、まとめて「左右風向板40」と称す)の回転により吹出方向が左右方向に吹き分けられ、上下前風向板50および上下後風向板60(以下、まとめて「上下風向板」と称す)の回転により吹出方向が上下方向に吹き分けられる。
(During driving)
In the indoor unit 100 of the air conditioner configured as described above, when an operation command is input, the indoor air sucked from the suction port 16 by the rotation of the blower fan 30 is removed by the filter 18 and cooled by the heat exchanger 20. Or it changes into warm air, and it blows off from the blower outlet 17 via the blowing wind path 33. FIG. At that time, the blowing direction is blown into the left and right directions by the rotation of the left and right wind direction plates 40L and 40R (hereinafter collectively referred to as “left and right wind direction plates 40”). The blowing direction is blown up and down by the rotation of the “upper and lower wind direction plates” collectively.

(上下風向板)
図5は冷房運転を示している。冷風は下に降りやすいため、上下前風向板50および上下後風向板60を少し回転して、略水平になっている。したがって、冷風は略水平に吹き出される。
図6は暖房運転を示している。温風は上に昇りやすいため、上下前風向板50および上下後風向板60を大きく回転して、略鉛直になっている。したがって、温風は略鉛直下方に吹き出される。
(Vertical wind direction plate)
FIG. 5 shows the cooling operation. Since the cold wind is likely to descend downward, the up / down front wind direction plate 50 and the up / down rear wind direction plate 60 are slightly rotated to be substantially horizontal. Therefore, the cold air is blown out substantially horizontally.
FIG. 6 shows the heating operation. Since the warm air is likely to rise upward, the up / down front wind direction plate 50 and the up / down rear wind direction plate 60 are largely rotated to be substantially vertical. Therefore, the warm air is blown out substantially vertically downward.

すなわち、上下方向に関しては、上下前駆動モーター57L、57Rおよび上下後駆動モーター67L、67Rの回転により上下前風向板50および上下後風向板60を回転させる。なお、上下前風向板50L、50Rおよび上下後風向板60L、60Rは、それぞれ独立して回転されるものであるから(それぞれに独立した上下前駆動モーター57L等が接続されている)、それぞれの回転角度を変更、すなわち、それぞれの吹出角度を変更してもよい。例えば、正面視において右側では略水平方向に、正面視において左側では略斜め下方向に、吹き出すようにすることができる。   That is, in the vertical direction, the vertical front and rear wind direction plates 50 and 60 are rotated by the rotation of the vertical front and rear drive motors 57L and 57R and the vertical and vertical rear drive motors 67L and 67R. In addition, since the up / down front wind direction plates 50L, 50R and the up / down rear wind direction plates 60L, 60R are each independently rotated (the independent up / down front drive motor 57L and the like are connected to each), each of them. You may change a rotation angle, ie, change each blowing angle. For example, it can be blown out in a substantially horizontal direction on the right side when viewed from the front, and substantially obliquely downward on the left side when viewed from the front.

前記のように、上下前風向板50および上下後風向板60はそれぞれ矩形状の羽根部分51および羽根部分61を具備し、一方の羽根端部52および端面62は、吹出口17の外側(風路側壁70と筐体側面15との間)に位置している。
そして、風路側壁70とモーター覆い板80とに跨って前逃がし溝91および後逃がし溝92が形成されているから、前記回転によって、羽根部分51の後面側の羽根側縁58および羽根部分61の後面側の羽根側縁68は、羽根端部52に近い所定範囲がモーター覆い板前切欠部81および風路側壁前切欠部71に侵入しながら、吹出風路33内に侵入して、上流側に移動することができる。
したがって、室内機100は、上下前風向板50の羽根端部52と風路側壁70との間に、および上下後風向板60の羽根端部62と風路側壁70との間に、隙間を形成しないようにすると共に、上下前風向板50および上下後風向板60の回転を可能にしている。
As described above, the up / down front wind direction plate 50 and the up / down rear wind direction plate 60 each include the rectangular blade portion 51 and the blade portion 61, and the one blade end portion 52 and the end surface 62 are outside the air outlet 17 (wind (Between the road side wall 70 and the housing side surface 15).
Since the front escape groove 91 and the rear escape groove 92 are formed across the air passage side wall 70 and the motor cover plate 80, the blade side edge 58 and the blade portion 61 on the rear surface side of the blade portion 51 are formed by the rotation. The blade side edge 68 on the rear surface side enters the blowout air passage 33 while a predetermined range close to the blade end portion 52 enters the motor cover plate front notch portion 81 and the air passage side wall front notch portion 71, Can be moved to.
Therefore, the indoor unit 100 has a gap between the blade end portion 52 of the front and rear wind direction plate 50 and the air passage side wall 70 and between the blade end portion 62 of the up and down rear air direction plate 60 and the air passage side wall 70. The upper and lower front wind direction plates 50 and the upper and lower rear wind direction plates 60 are allowed to rotate.

(左右風向板)
左右風向板40は、斜め下方に向かう回転支持部42によって回転自在に支持された複数枚の羽根41(図4において、羽根41La、41Lbの一方のみ描いている)と、回転支持部42から所定距離離れた位置において、羽根41に回動自在に設置された左右移動棒43と、左右移動棒43に接続された左右リンク棒44と、左右リンク棒44を駆動する左右駆動カム45と、左右駆動カム45を回転する左右駆動モーター46とを、有している。
したがって、左右方向に関しては、左右駆動モーター46Lの回転によって、左右風向板40Lを左右方向に所定の角度だけ回転させ、吹出方向を左右方向で制御している。
このとき、左右風向板40Lを左右方向に大きく回転させて、調和空気を大きく外側に向かって吹き出す際、モーター覆い板80にはモーター覆い板面取り部分83が形成されている(風路側壁70のモーター覆い板80に近い範囲が、外側に向かって拡がっている)から、吹き出された調和空気が風路側壁70に遮られることがなく、スムースに吹き出される。したがって、室内の広い範囲に調和空気を送り出すことができる。
(Left and right wind direction plate)
The left and right wind direction plates 40 are provided with a plurality of blades 41 (only one of the blades 41La and 41Lb is drawn in FIG. 4) rotatably supported by a rotation support portion 42 that is inclined obliquely downward. In a position separated by a distance, a left / right moving rod 43 rotatably installed on the blade 41, a left / right link rod 44 connected to the left / right moving rod 43, a left / right drive cam 45 for driving the left / right link rod 44, And a left and right drive motor 46 that rotates the drive cam 45.
Therefore, with respect to the left and right direction, the left and right wind direction plate 40L is rotated by a predetermined angle in the left and right direction by the rotation of the left and right drive motor 46L, and the blowing direction is controlled in the left and right direction.
At this time, the motor cover plate 80 is formed with a motor cover plate chamfered portion 83 when the left and right wind direction plates 40L are largely rotated in the left and right direction and the conditioned air is greatly blown outward. Since the range close to the motor cover plate 80 extends outward), the blown conditioned air is smoothly blown out without being blocked by the air passage side wall 70. Therefore, conditioned air can be sent out over a wide range in the room.

さらに、上下前風向板50の羽根端部52および上下後風向板60の羽根端部62は筐体側面15に近く、モーター覆い板面取り部分83を覆うことができる拡がりを具備しているから、調和空気が大きく外側に向かって吹き出された場合でも、該調和空気は羽根端部52および羽根端部62に近い範囲において所定の上下方向に案内される。
なお、吹出風路33には、左右方向に、左右風向板40Lとこれと略面対称に同様の左右風向板が設置され、それぞれ独立に回転されるから、それぞれを所定の回転角度に回転することによって、調和空気の左右方向の吹出方向を所定の方向に集中したり、所定の吹出範囲に拡げたりする(例えば、吹出口17の左側半分からは左外側に向けて、吹出口17の右側半分からは正面方向に向けて吹き出す)ことが可能になっている。
Further, the blade end portion 52 of the up / down front wind direction plate 50 and the blade end portion 62 of the up / down rear wind direction plate 60 are close to the casing side surface 15 and have an extension that can cover the motor cover plate chamfered portion 83. Even when the conditioned air is blown largely outward, the conditioned air is guided in a predetermined vertical direction within a range close to the blade end portion 52 and the blade end portion 62.
Note that the left and right wind direction plates 40L and the same left and right wind direction plates are installed in the left and right direction in the left and right direction and are rotated independently of each other in the left and right direction. As a result, the right and left blowout directions of the conditioned air are concentrated in a predetermined direction or expanded to a predetermined blowout range (for example, from the left half of the blowout port 17 toward the left outer side, the right side of the blowout port 17 It is possible to blow out from the front in the front direction).

図7〜図9において、空気調和機の室内機(以下、単に「室内機」と称す)200は、室内機100(実施の形態1)における後逃がし溝92を撤去し、室内機100における上下後風向板60に替えて、上下後風向板60の一方の羽根端部62と後面側の羽根側縁68との角に、風向板切欠部69を設けたもの(以下、「上下後風向板260」と称す)を設置したものである。
[Embodiment 2]
7 to 9 illustrate an indoor unit of an air conditioner according to Embodiment 2 of the present invention. FIG. 7 is a perspective view schematically showing the whole, and FIG. FIG. 9 is a perspective view showing an up / down air direction plate during cooling operation. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and one part description is abbreviate | omitted.
7 to 9, an indoor unit (hereinafter simply referred to as “indoor unit”) 200 of the air conditioner removes the rear relief groove 92 in the indoor unit 100 (Embodiment 1), and In place of the rear wind direction plate 60, a wind direction plate notch 69 is provided at the corner between one blade end 62 and the rear blade side edge 68 of the upper and lower rear wind direction plates 60 (hereinafter referred to as "upper and lower rear wind direction plates"). 260 ”).

すなわち、後逃がし溝92がないにも関わらず、風向板切欠部69を設けることによって、回転時に、上下後風向板260がモーター覆い板80に干渉(衝突)しないようにしている。
したがって、左右駆動カム45Lや左右駆動モーター46Lと上下後駆動モーター67Lとの間に、後逃がし溝92を設けるスペースが確保できない場合に好適である。
なお、運転停止時に、モーター覆い板80およびモーター覆い板前切欠部83の後面寄りの範囲は、室内機100よりも広い範囲が覆われなかったり、風路側壁70と風向板切欠部69との間に隙間が生じたりするものの、筐体後面12に近い範囲であることから、意匠性が大きく阻害されることはない。
That is, although the rear escape groove 92 is not provided, the wind direction plate notch portion 69 is provided so that the upper and lower rear wind direction plates 260 do not interfere (collision) with the motor cover plate 80 during rotation.
Therefore, it is suitable when the space for providing the rear relief groove 92 cannot be secured between the left / right drive cam 45L or the left / right drive motor 46L and the upper / lower rear drive motor 67L.
When the operation is stopped, the range near the rear surface of the motor cover plate 80 and the motor cover plate front notch 83 is not covered by the area wider than the indoor unit 100, or between the air passage side wall 70 and the wind direction plate notch 69. However, the design is not significantly hindered because it is in a range close to the rear surface 12 of the housing.

[Embodiment 3]
10 to 15 illustrate an indoor unit of an air conditioner according to Embodiment 3 of the present invention. FIG. 10 is a cross-sectional view schematically showing the whole, and FIG. FIG. 12 is a side view showing an enlarged part (airway side wall), FIG. 13A is a front view showing an enlarged part (airway side wall), and FIG. 13B is a perspective view showing a part (air passage side wall) in an enlarged manner, FIG. 14 is a front view schematically showing a part (projection part) of the wind flow, and FIG. 15 is a part (projection part). It is a characteristic view which shows the relationship between fan and fan input.
In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and one part description is abbreviate | omitted. Similarly to the first embodiment, common contents will be described by omitting the description of the suffixes “L, R”.

図10〜図14において、空気調和機の室内機(以下、単に「室内機」と称す)300は、実施の形態1に示す室内機100に、左右方向の外側に吹き出された調和空気が、風路側壁前切欠部71および風路側壁後切欠部72への侵入を防止するための、風路側壁前突起部77および風路側壁後突起部78と、調和空気の吹出幅を拡大するための風路後壁リブ79とを設けたものに同じである。   10 to 14, an indoor unit (hereinafter simply referred to as “indoor unit”) 300 of an air conditioner is configured such that conditioned air blown to the outside in the left-right direction is blown to the indoor unit 100 described in the first embodiment. To prevent the air passage side wall front notch portion 71 and the air passage side wall rear notch portion 72 from entering the air passage side wall front projection portion 77 and the air passage side wall rear projection portion 78, and to increase the blowing width of the conditioned air. It is the same as that provided with the air channel rear wall rib 79.

(風路側壁前突起部)
風路側壁前突起部77は、風路側壁前切欠部71の送風ファン30に近い側の側縁(風路側壁前切欠部71の風上側)に沿って設置されている。
すなわち、風路側壁前突起部77は、モーター収納庫90の前逃がし溝91を形成する風上側の逃がし側板91b(図12参照)に沿って、筐体10の中央方向(風路側壁70に略垂直に同じ)に突出した前突起部壁面77aと、前突起部壁面77aの頂点(稜線)から風上側になるに従って風路側壁70に接近する前突起部風上斜面77bと、前突起部壁面77aの頂点(稜線)のモーター覆い板面取り部分83に相当する範囲であって、モーター覆い板80(筐体10の外側に同じ)に向かって傾斜した前突起部外側斜面77cと、モーター覆い板面取り部分83に相当する範囲であって、前突起部風上斜面77bのモーター覆い板80(筐体10の外側に同じ)の側縁と、前突起部外側斜面77cの風上側の側縁とを連結して、モーター覆い板80および風上側に向かって傾斜した前突起部繋ぎ斜面77dと、を有している。
(Air channel side front protrusion)
The air channel side wall front protrusion 77 is disposed along the side edge of the air channel side wall front notch portion 71 on the side close to the blower fan 30 (windward side of the air channel side wall front notch portion 71).
That is, the air channel side wall front projection 77 is located in the center direction of the housing 10 (on the air channel side wall 70) along the windward escape side plate 91 b (see FIG. 12) that forms the front escape groove 91 of the motor storage 90. A front projection wall surface 77a projecting in the substantially vertical direction), a front projection windward slope 77b approaching the air passage side wall 70 from the apex (ridgeline) of the front projection wall surface 77a toward the windward side, and the front projection A front projection outer slope 77c inclined toward the motor cover plate 80 (same as the outside of the housing 10), which corresponds to the motor cover plate chamfered portion 83 at the apex (ridgeline) of the wall surface 77a, and the motor cover A side edge of the motor covering plate 80 (same as the outside of the housing 10) of the front projection windward slope 77b and a windward side edge of the front projection outer slope 77c are ranges corresponding to the plate chamfered portion 83. And the motor It has a front protrusion connecting slope 77d which is inclined toward the cover plate 80 and the windward side.

なお、図中、前突起部壁面77a、前突起部風上斜面77b、前突起部外側斜面77cおよび前突起部繋ぎ斜面77dのそれぞれの境界を、模式的に実線にて描いているが、実際は、それぞれの境界は面取りされ、滑らかに繋がっている。すなわち、風路側壁前突起部77は、風下側が逃がし側板91bに連なる絶壁(垂直壁)と、風上側が傾斜し、風路側壁70に連なる裾野とを有する略直角三角柱状の断面を有する山脈を呈している。   In the drawing, the boundaries of the front projection part wall surface 77a, the front projection part upwind slope 77b, the front projection part outer slope 77c, and the front projection part connection slope 77d are schematically drawn by solid lines. Each boundary is chamfered and connected smoothly. That is, the air channel side front projection 77 has a substantially right triangular prism-shaped cross section having a precipice (vertical wall) that is connected to the escape side plate 91b on the leeward side and a skirt that is inclined on the wind side and connected to the air channel side wall 70 Presents.

(風流れ)
したがって、風路側壁70の近くを流れる調和空気は、風路側壁前突起部77の前突起部風上斜面77bに案内され、筐体10の斜め中央方向に向かう方向に流れ方向をスムーズに曲げられ、流れる。同様に、モーター覆い板面取り部分83の近くを流れる調和空気は、風路側壁前突起部77の前突起部繋ぎ斜面77dおよび前突起部外側斜面77cに案内され、筐体10の斜め中央方向に向かう方向に流れ方向をスムーズに曲げられ、流れる(図15参照)。
すなわち、風路側壁前切欠部71を飛び越えるような風流れ(以下、「前突起部風流れ」と称す)W77がスムーズに形成されるから、調和空気の風路側壁前切欠部71への侵入が、効率的に防止される。
また、左右風向板40を外側に向けた場合、全体として外側に向かう調和空気の流れ(以下、「全体風流れ」と称す)W40、つまり、風路側壁前切欠部71に向かう全体風流れW40は、前突起部風流れW77に衝突(干渉)するから、調和空気の風路側壁前切欠部71への侵入が防止される。
(Wind flow)
Therefore, the conditioned air flowing near the air channel side wall 70 is guided by the front projection windward slope 77b of the air channel side wall front projection 77, and the flow direction is smoothly bent in the direction toward the oblique central direction of the housing 10. And flow. Similarly, the conditioned air flowing in the vicinity of the motor cover plate chamfered portion 83 is guided by the front projecting portion connecting slope 77d and the front projecting portion outer slope 77c of the air passage side wall front projecting portion 77 in the oblique central direction of the housing 10. The flow direction is smoothly bent in the direction of the flow (see FIG. 15).
That is, since a wind flow W77 that jumps over the air channel side front notch 71 (hereinafter referred to as “front projection wind flow”) W77 is smoothly formed, the conditioned air enters the air channel side front notch 71. Is effectively prevented.
Further, when the left and right wind direction plates 40 are directed outward, the flow of conditioned air (hereinafter, referred to as “overall wind flow”) W40 toward the outside as a whole, that is, the overall wind flow W40 toward the airway side wall front notch 71. Impinges on (interfers with) the front projection wind flow W77, so that the conditioned air is prevented from entering the wind channel side wall front notch 71.

(着露)
なお、上下前風向板50および上下後風向板60が略水平方向に向いている場合、上下前風向板50の位置によってはモーター覆い板80が邪魔になって上下前風向板50の下側を調和空気が流れない場合があるが、このとき、風路側壁前切欠部71に調和空気が侵入して上下前風向板50の上側を流れてしまうことがある。
特に、高温多湿環境での冷房運転においては、上下前風向板50の上下で温度差が発生し、上下前風向板50の上側は冷えているのに上下前風向板50の下側の空気は高温多湿という状態になり、上下前風向板50の下面に着露してしまい、露が成長して室内に滴下してしまう恐れがある。
しかしながら、室内機300は、風路側壁前突起部77を有し、これによって風路側壁前切欠部71への調和空気の侵入を防ぐことができるから、前記上下前風向板50の上側の冷却が防止され、下面の着露が抑えられると共に、下面に着露した場合でも、着露した露が、成長して室内に滴下する危険が抑えられている。
(Dew condensation)
In addition, when the up / down front wind direction plate 50 and the up / down rear wind direction plate 60 are oriented in a substantially horizontal direction, depending on the position of the up / down front wind direction plate 50, the motor cover plate 80 may be in the way, and the lower side of the up / down front wind direction plate 50 may be lowered. In some cases, the conditioned air may not flow. At this time, the conditioned air may enter the front notch portion 71 on the air passage side wall and flow on the upper side of the front and rear wind direction plates 50.
In particular, in a cooling operation in a hot and humid environment, a temperature difference occurs between the upper and lower front wind direction plates 50, and the upper side of the upper and lower front wind direction plates 50 is cooled, but the air below the upper and lower front wind direction plates 50 is There is a risk of high-temperature and high-humidity, condensation on the lower surface of the up-and-down front wind direction plate 50, and dew growing and dripping into the room.
However, the indoor unit 300 has the air channel side wall front protrusion 77, which can prevent intrusion of conditioned air into the air channel side wall front notch 71. Is prevented, and the dew condensation on the lower surface is suppressed, and even when the lower surface is dewed, the risk of the dew that has grown and dropped into the room is suppressed.

(前突起部溝)
さらに、風路側壁前突起部77の前突起部壁面77a(逃がし側板91bに繋がる面)に、風路側壁70に略垂直の方向(左右方向)に前突起部溝77eが複数条が設けられている。したがって、仮に、前突起部風上斜面77bに沿った流れが調和空気が巻き込まれて、前突起部壁面77aに着露が発生した場合でも、前突起部溝77eが露を保持するから、露の滴下がさらに抑えられる。
なお、前突起部溝77eの形状、大きさ、数量は限定するものではなく、表面張力を利用して露を保持することができる程度の凹凸であればよい。また、前突起部壁面77aと逃がし側板91bとに跨って形成されたもの、あるいは、前突起部壁面77aと前突起部風上斜面77bとに跨って形成されたものであってもよい。
一方、前突起部壁面77aへの着露が少ない使用環境の場合には、前突起部溝77eの設置を省略してもよい。
(Front protrusion groove)
Further, a plurality of front protrusion grooves 77e are provided on the front protrusion wall surface 77a of the air passage side wall front protrusion 77 (the surface connected to the escape side plate 91b) in a direction substantially perpendicular to the air passage side wall 70 (left and right direction). ing. Therefore, even if the flow along the front projection portion upwind slope 77b is entangled with conditioned air and the front projection portion wall surface 77a is dewed, the front projection groove 77e retains the dew. Is further suppressed.
Note that the shape, size, and quantity of the front protrusion groove 77e are not limited, and may be irregularities that can retain dew using surface tension. Further, it may be formed across the front projection wall surface 77a and the escape side plate 91b, or may be formed across the front projection wall surface 77a and the front projection windward slope 77b.
On the other hand, in a usage environment where the dew condensation on the front projection wall surface 77a is small, the installation of the front projection groove 77e may be omitted.

(風路側壁前突起部の高さ等)
図15は、縦軸が送風ファンの入力増加量、横軸は風路側壁前突起部77の高さ(前突起部壁面77aの頂点(稜線)と風路側板70との距離)である。図15において、風路側壁前突起部77の高さが15mmを超えると、高くなるに従って、ファンモーター入力が急激に増大する。したがって、風路側壁前突起部77の高さを15mm程度にしておけば、ファンモーター入力への影響はほとんどないため、室内機300が必要とする電力量を、ほとんど増加させないで、前記着露の発生を抑えることができる。
なお、前記のように、風路側壁前切欠部71への調和空気の侵入を防ぐことができれば、着露の発生を抑え、引いては露の室内への滴下を防ぐことができるため、風路側壁前突起部77の形状は、前記のような断面略三角形(略直角三角形)の柱状に限定するものではなく、前突起部風上斜面77bを曲面(例えば、凹面)にしたり、通風抵抗は大きくなるものの、平板リブ(前突起部風上斜面77bが前突起部壁面77aに平行)等あってもよい。
(Height of airway side wall front projection etc.)
In FIG. 15, the vertical axis represents the input increase amount of the blower fan, and the horizontal axis represents the height of the air channel side wall front projection 77 (the distance between the apex (ridgeline) of the front projection wall surface 77 a and the air channel side plate 70). In FIG. 15, when the height of the air channel side wall front projection 77 exceeds 15 mm, the fan motor input increases rapidly as the height increases. Therefore, if the height of the air channel side wall front projection 77 is set to about 15 mm, there is almost no influence on the fan motor input. Therefore, the amount of power required by the indoor unit 300 is hardly increased and the dew condensation is increased. Can be suppressed.
Note that, as described above, if the conditioned air can be prevented from entering the air channel side wall front notch 71, the occurrence of dew condensation can be suppressed, and pulling of the dew into the room can be prevented. The shape of the road side wall front projection 77 is not limited to a column shape having a substantially triangular cross section (substantially right triangle) as described above, and the front projection upwind slope 77b has a curved surface (for example, a concave surface). However, it may be a flat plate rib (the front projection windward slope 77b is parallel to the front projection wall 77a).

(風路側壁後突起部)
風路側壁後突起部78は、風路側壁後切欠部72の送風ファン30に近い側の側縁(風路側壁後切欠部72の風上側)に沿って設置され、風路側壁前突起部77と同様の構造である。
すなわち、風路側壁後突起部78は、モーター収納庫90の後逃がし溝92を形成する風上側の逃がし側板92b(図12参照)に沿って、筐体10の中央方向(風路側壁70に略垂直に同じ)に突出した後突起部壁面78aと、後突起部壁面78aの頂点(稜線)から風上側になるに従って風路側壁70に接近する後突起部風上斜面78bと、後突起部壁面78aの頂点(稜線)のモーター覆い板面取り部分83に相当する範囲であって、モーター覆い板80(筐体10の外側に同じ)に向かって傾斜した後突起部外側斜面78cと、モーター覆い板面取り部分83に相当する範囲であって、後突起部風上斜面78bのモーター覆い板80(筐体10の外側に同じ)の側縁と、後突起部外側斜面78cの風上側の側縁とを連結して、モーター覆い板80および風上側に向かって傾斜した後突起部繋ぎ斜面78dと、を有している。
さらに、風路側壁後突起部78の後突起部壁面78a(逃がし側板92bに繋がる面)に、風路側壁70に略垂直の方向(左右方向)に複数条の後突起部溝78eが設けられている。
(Air channel side wall rear projection)
The air channel side wall rear projection 78 is installed along the side edge of the air channel side wall rear notch 72 close to the blower fan 30 (the windward side of the air channel side wall rear notch 72), and the air channel side wall front projection This is the same structure as 77.
That is, the air channel side wall rear protrusion 78 is arranged in the center direction of the housing 10 (on the air channel side wall 70) along the windward escape side plate 92 b (see FIG. 12) that forms the rear escape groove 92 of the motor storage 90. A rear projection wall surface 78a that projects substantially vertically), a rear projection windward slope 78b that approaches the airway side wall 70 from the apex (ridgeline) of the rear projection wall surface 78a toward the windward side, and a rear projection A rear projection outer slope 78c inclined toward the motor cover plate 80 (same as the outside of the housing 10), which corresponds to the motor cover plate chamfered portion 83 at the apex (ridgeline) of the wall surface 78a, and the motor cover A side edge of the motor covering plate 80 (same as the outside of the housing 10) of the rear projection windward slope 78b and a windward side edge of the rear projection outer slope 78c are ranges corresponding to the plate chamfered portion 83. And the motor Connecting projections was inclined toward the cover plate 80 and the windward side has a slope 78d, a.
Further, a plurality of rear protrusion grooves 78e are provided on the rear protrusion wall surface 78a (surface connected to the escape side plate 92b) of the air passage side wall rear protrusion 78 in a direction (right and left direction) substantially perpendicular to the air passage side wall 70. ing.

したがって、風路側壁後突起部78は、風路側壁前突起部77と同様の作用効果を奏する。すなわち、風路側壁後切欠部72への調和空気の侵入を防ぐことができるから、上下後風向板60の上側の冷却が防止され、下面の着露が抑えられると共に、下面に着露した場合でも、着露した露が、成長して室内に滴下する危険が抑えられている。
さらに、仮に、後突起部壁面78aに着露が発生した場合でも、後突起部溝78eが露を保持するから、露の滴下がさらに抑えられる。
Therefore, the air channel side wall rear projection 78 has the same effect as the air channel side wall front projection 77. That is, since the conditioned air can be prevented from entering the rear notch portion 72 on the air channel side wall, the upper side of the upper and lower rear wind direction plates 60 can be prevented from being cooled, and the lower surface can be prevented from condensing and the lower surface can be dewed. However, the risk that the dew that has formed grows up and drops into the room is reduced.
Furthermore, even if dew condensation occurs on the rear projection wall surface 78a, the rear projection groove 78e holds the dew, so that dripping of the dew is further suppressed.

(風路後壁リブ)
風路後壁32の、吹出口17近傍で、かつ風路側壁70近傍の位置に、風路後壁リブ79が設けられている。左右方向で、吹出口17の幅が送風ファン30の幅よりも広いため、風路側壁70(吹出口17の側端部に相当する)が送風ファン30の側端部よりも外側に位置しているものの、送風ファン30によって送り出された調和空気は、風路後壁リブ79によって、風路側壁70側に案内される。
つまり、調和空気を外側に吹き出したいときに、調和空気は風路後壁リブ79によって、よりスムーズに外側に吹き出される。したがって、室内の広範囲に調和空気を送り出すことができる。
さらに、風路後壁リブ79により調和空気に小さな渦が多数発生するため、調和空気が上下後風向板60に沿いやすくなり、調和空気はよりスムーズに吹き出される。したがって、室内の広範囲に調和空気を送り出すことができる。
なお、風路後壁リブ79は単数でも構わないが、複数枚あったほうがより高い効果を得ることができる。
ここで、風路後壁リブ79には複数条の風路厚壁リブ溝(凹凸)79aが設けられ、仮に、風路後壁リブ79そのものに着露が発生した場合でも、風路厚壁リブ溝79aに露を保持させて露の滴下が生じないようにしている。
なお、以上は、風路側壁前突起部77と風路側壁後突起部78と風路後壁リブ79との3部材が設けられ、大きな効果を得ることができるが、本発明はこれに限定するものではなく、少なくとも何れか1部材が設けられたものであってもよい。
(Rear wall rear wall rib)
An air passage rear wall rib 79 is provided on the air passage rear wall 32 in the vicinity of the air outlet 17 and in the vicinity of the air passage side wall 70. Since the width of the air outlet 17 is wider than the width of the blower fan 30 in the left-right direction, the air passage side wall 70 (corresponding to the side end of the air outlet 17) is located outside the side end of the blower fan 30. However, the conditioned air sent out by the blower fan 30 is guided to the air passage side wall 70 side by the air passage rear wall rib 79.
That is, when it is desired to blow out conditioned air to the outside, the conditioned air is blown out to the outside more smoothly by the air passage rear wall rib 79. Therefore, conditioned air can be sent out over a wide range in the room.
Further, since many small vortices are generated in the conditioned air by the air passage rear wall rib 79, the conditioned air becomes easy to follow along the upper and lower rear wind direction plates 60, and the conditioned air is blown out more smoothly. Therefore, conditioned air can be sent out over a wide range in the room.
In addition, although the air path rear wall rib 79 may be single, the more effect can be acquired when there are several.
Here, the air passage rear wall rib 79 is provided with a plurality of air passage thick wall rib grooves (unevenness) 79a, and even if dew condensation occurs on the air passage rear wall rib 79 itself, the air passage thick wall Dew is retained in the rib groove 79a to prevent the dew from dropping.
In the above, three members of the air channel side wall front projection 77, the air channel side wall rear projection 78, and the air channel rear wall rib 79 can be provided, and a great effect can be obtained, but the present invention is limited to this. However, at least any one member may be provided.

図16および図17において、空気調和機の室内機(以下、単に「室内機」と称す)400は、実施の形態2に示す室内機200における風路側壁前切欠部71および風路後壁32に、それぞれ実施の形態3に示す風路側壁前突起部77および風路後壁リブ79を設けたものに同じである。
したがって、風路側壁前突起部77によって、風路側壁前切欠部71への調和空気の侵入を防ぐことができるから、上下前風向板50の下面の着露が抑えられると共に、下面に着露した場合でも、着露した露が、成長して室内に滴下する危険が抑えられている。
また、仮に、前突起部壁面77aに着露が発生した場合でも、前突起部溝77eが露を保持するから、露の滴下がさらに抑えられる。
さらに、調和空気は風路後壁リブ79によって、よりスムーズに外側に吹き出されるから、室内の広範囲に調和空気を送り出すことができる。
なお、以上は、風路側壁前突起部77と風路後壁リブ79との2部材が設けられ、大きな効果を得ることができるが、本発明はこれに限定するものではなく、少なくとも何れか1部材が設けられたものであってもよい。
16 and 17, an air conditioner indoor unit (hereinafter simply referred to as “indoor unit”) 400 includes an air channel side wall front notch 71 and an air channel rear wall 32 in the indoor unit 200 shown in the second embodiment. In addition, the air passage side wall front projection 77 and the air passage rear wall rib 79 are the same as those shown in the third embodiment.
Therefore, since the conditioned air can be prevented from intruding into the air channel side wall front notch portion 71 by the air channel side wall front protrusion 77, the dew condensation on the lower surface of the front and rear wind direction plates 50 is suppressed and the air surface is dewed. Even in this case, the risk of the dew that has grown and dripping into the room is reduced.
Even if dew condensation occurs on the front projection wall surface 77a, the front projection groove 77e holds the dew, so that dripping of the dew is further suppressed.
Furthermore, since the conditioned air is blown out more smoothly by the air passage rear wall rib 79, the conditioned air can be sent out over a wide range in the room.
The above is provided with two members, the air channel side wall front projection 77 and the air channel rear wall rib 79, and can provide a great effect. However, the present invention is not limited to this, and at least any one of them. One member may be provided.
