Also, the blade base 15 of the horizontal wind direction changing blade 9 can be located outside the ventilation passage 7 when cleaning the ventilation passage 7 and the like, and therefor, the ventilation passage 7 can be opened by turning, toward this side, a free end part as a center side end part of the blowout port 6 in the blade base 15 without inserting the hand into the depth in the ventilation passage 7, so that cleaning in the ventilation passage 7 is facilitated.SELECTED DRAWING: Figure 2

Description

本発明は空気調和機に関するものである。 The present invention relates to an air conditioner.

一般に空気調和機は、空気調和機本体の吸込口から吸い込んだ空気を熱交換器で熱交換した後、熱交換後の空気を吹出口から吹き出し、室内を空調する。空気調和機の運転時、吸込口から吸い込んだ空気中の塵埃等がフィルタを通り抜け、通風路や風向変更羽根等に付着してしまう。 Generally, in an air conditioner, the air sucked from the suction port of the air conditioner body is heat-exchanged by a heat exchanger, and then the air after heat exchange is blown out from the air outlet to air-condition the room. During operation of the air conditioner, dust and the like in the air sucked from the suction port passes through the filter and adheres to the ventilation passage, the airflow direction changing blade, and the like.

そのため、通風路や風向変更羽根等に付着した塵埃等を容易に掃除できる空気調和機が提案されている。 Therefore, there has been proposed an air conditioner that can easily clean dust and the like adhering to the ventilation passage and the wind direction changing vanes.

図１０は空気調和機本体内の通風路や風向変更羽根等に付着した塵埃の掃除を容易にした空気調和機である。図１０における空気調和機は、通風路１０４の下流側に設けた左右羽根１０２のベーンベース１０３を、図１１に示すように略中央部で二つに分割し、ベーンベース１０３の両端を回動可能に係止し、本体内部清掃時はベーンベース１０３を回動させ、ベーンベース１０３の位置を変更して、通風路１０４を開放する構成としてある。 FIG. 10 shows an air conditioner that facilitates the cleaning of dust adhering to the ventilation passages in the air conditioner body and the airflow direction changing vanes. In the air conditioner shown in FIG. 10, the vane base 103 of the left and right blades 102 provided on the downstream side of the ventilation passage 104 is divided into two at approximately the central portion as shown in FIG. 11, and both ends of the vane base 103 are rotated. The configuration is such that the vane base 103 is pivoted when the inside of the main body is cleaned, the position of the vane base 103 is changed, and the ventilation passage 104 is opened.

上記構成によれば、複数の板状部材からなる左右羽根１０２を吹出口１０１から取り外さなくても通風路１０４を開放できるので、通風路１０４や左右羽根１０２の掃除が容易にできる、というものである。 According to the above configuration, since the ventilation passage 104 can be opened without removing the left and right blades 102 formed of a plurality of plate-shaped members from the outlet 101, the ventilation passage 104 and the left and right blades 102 can be easily cleaned. is there.

特許第３５６７８５３号公報Japanese Patent No. 3567853

しかしながら、上記空気調和機は、左右羽根１０２のベーンベース１０３を通風路１０４に設けてあるため、通風路１０４における通風抵抗が大きくなり、吹出性能が低下するという問題があった。 However, since the above-mentioned air conditioner is provided in the ventilation passage 104 of the vane base 103 of the left and right blades 102, there is a problem in that the ventilation resistance in the ventilation passage 104 increases and the blowing performance deteriorates.

また、通風路１０４内等の掃除が容易になるものの、左右羽根１０２を取り付けたベーンベース１０３を回動させる前に、上下羽根１０５を吹出口１０１から取り外す必要があった。さらに、ベーンベース１０３が吹出口１０１の上流側に位置しているため、吹出口１０１の奥側の狭いスペースに手を挿入してベーンベース１０３の端部を手前に回動させるという困難な操作が必要であった。つまり、掃除のしやすさという観点からは不十分であった。 Further, although it is easy to clean the inside of the ventilation passage 104 and the like, it is necessary to remove the upper and lower blades 105 from the outlet 101 before rotating the vane base 103 to which the left and right blades 102 are attached. Furthermore, since the vane base 103 is located on the upstream side of the outlet 101, a difficult operation of inserting a hand into a narrow space on the back side of the outlet 101 and rotating the end of the vane base 103 toward you. Was needed. That is, it was insufficient from the viewpoint of easy cleaning.

本発明は上記の問題に鑑みてなしたもので、吹出性能を低下させることなく容易に掃除ができる空気調和機の提供を目的としたものである。 The present invention has been made in view of the above problems, and an object of the present invention is to provide an air conditioner that can be easily cleaned without lowering the blowing performance.

本発明は、上記目的を達成するため、左右風向変更羽根は、上下風向変更羽根の一面に設けた羽根ベースを介して、羽根ベースの一端を中心として回動可能である構成としてある。 In order to achieve the above object, the present invention has a configuration in which the left and right wind direction changing blades are rotatable around one end of the blade base via a blade base provided on one surface of the vertical wind direction changing blade.

左右風向変更羽根は、上下風向変更羽根の一面に設けられているため、上下風向変更羽根が回動し、吹出口が開口することに伴い、左右風向変更羽根は、吹出口の下流に移動する。そのため、左右風向変更羽根が送風ファン近くの流速の速い通風路奥側に位置する従来のものに比べ、風路抵抗を低減し高性能化を図ることができる。 Since the left/right airflow direction changing blade is provided on one surface of the up/down airflow direction changing blade, the left/right airflow direction changing blade moves downstream of the air outlet as the up/down airflow direction changing blade rotates to open the air outlet. .. Therefore, as compared with the conventional one in which the left and right airflow direction changing blades are located on the far side of the ventilation passage near the blower fan with a high flow velocity, it is possible to reduce the air passage resistance and achieve higher performance.

また、左右風向変更羽根は羽根ベースを介して、羽根ベースの一端を中心として回動可能であるため、通風路内等を掃除する際、左右風向変更羽根の羽根ベースを通風路の外に位置させることができる。そのため、通風路内の奥まで手を挿入しなくても、羽根ベースにおける吹出口中央側端部である自由端部を手前に移動させて通風路を開放することができ、通風路内等の掃除が容易になる。 In addition, since the left and right airflow direction changing blades are rotatable around the one end of the blade base via the blade base, the blade bases of the left and right airflow direction changing blades are located outside the airflow passage when cleaning the inside of the airflow passage. Can be made Therefore, even if the hand is not inserted all the way to the inside of the ventilation passage, the free end, which is the end of the blade base on the center side of the outlet, can be moved forward to open the ventilation passage. Easy to clean.

本発明は、上記構成により、本体通風路内の掃除がしやすく、吹出性能も良好な空気調和機を提供することができる。 The present invention can provide an air conditioner having the above-mentioned configuration, which makes it easy to clean the inside of the air passage of the main body and has good blowing performance.

第１の発明は、本体と、前記本体内に設けた熱交換器及び送風ファンと、前記送風ファンの送風方向の下流側に設けた通風路と、前記通風路の下流側に設けた上下風向変更羽根と、左右風向変更羽根と、前記上下風向変更羽根の一面に設けた羽根ベースと、を備え、前記左右風向変更羽根は、前記羽根ベースを介して、前記羽根ベースの一端を中心として回動可能である構成としてある。 A first invention is a main body, a heat exchanger and a blower fan provided in the main body, a ventilation passage provided at a downstream side of a blowing direction of the blower fan, and a vertical wind direction provided at a downstream side of the ventilation passage. A change blade, a left/right wind direction changing blade, and a blade base provided on one surface of the up/down wind direction changing blade, and the left/right wind direction changing blade is rotated about one end of the blade base via the blade base. It is configured to be movable.

第２の発明は、第１の発明において、前記上下風向変更羽根は、一面に段部を有し、前記段部に前記羽根ベースを設けた構成としてある。 In a second aspect based on the first aspect, the vertical airflow direction changing blade has a step portion on one surface, and the blade base is provided on the step portion.

これにより、上下風向変更羽根の一面に設けた左右風向変更羽根の羽根ベースが、上下風向変更羽根の上面に沿って流れる空気の抵抗が増加することを抑制でき、吹出性能を向上させてより高性能化することができる。 As a result, the blade base of the left/right airflow direction changing blade provided on one surface of the up/down airflow direction changing blade can suppress an increase in the resistance of the air flowing along the upper surface of the up/down airflow direction changing blade, improving the blowing performance and increasing the airflow. It can be improved.

第３の発明は、第１または第２の発明において、前記左右風向変更羽根と前記羽根ベースをそれぞれ二つずつ備え、それぞれの前記左右風向変更羽根は、一つの前記羽根ベースを介して、前記上下風向変更羽根の両端部に一つずつ回動可能に設けられた構成としてある。 3rd invention is a 1st or 2nd invention, Comprising: The said right-and-left airflow direction change blade and two said blade bases are each provided, and each said left-right airflow direction change blade is the said blade base via one said blade base. The upper and lower wind direction changing blades are provided so as to be rotatable one by one at both ends.

これにより、羽根ベースの手前側への回動操作が吹出口の略中央部分で行えるので、羽根ベースの回動操作が容易にでき、通風路内の掃除が容易になる。 Accordingly, since the blade base can be rotated toward the front side at the substantially central portion of the outlet, the blade base can be easily rotated and the inside of the ventilation passage can be easily cleaned.

第４の発明は、第１〜第３の発明において、前記上下風向変更羽根は前記本体に回動可能に支持された軸部を有し、前記羽根ベースは、前記上下風向変更羽根に前記軸部より下流側で回動可能に設けられた構成としてある。 In a fourth aspect based on the first to third aspects, the vertical airflow direction changing vane has a shaft portion rotatably supported by the main body, and the blade base includes the shaft in the vertical airflow direction changing vane. It is configured to be rotatable on the downstream side of the section.

これにより、左右風向変更羽根の羽根ベースの奥側端部を含むほぼ全体が、通風路の外側に位置するので、羽根ベースの手前への回動操作性が向上し、掃除が更に容易なものとなる。また、左右風向変更羽根を脱着する必要がある場合、羽根ベースの吹出口端部の回転軸が通風路外に位置するので、羽根ベースの脱着も容易になり、掃除の容易化をより一層高めることができる。 As a result, almost the entire right and left airflow direction changing blades, including the rear side end of the blade base, are located outside the ventilation passage, so the operability of rotating the blade base toward the front is improved and cleaning is easier. Becomes Further, when the left/right airflow direction changing blades need to be attached/detached, the rotation axis of the air outlet end portion of the blade base is located outside the ventilation passage, so that the blade base can be easily attached/detached to further facilitate cleaning. be able to.

The filter 10 includes a frame portion and a net portion held by the frame portion. The air conditioner according to the present embodiment includes a filter cleaning unit 11 that automatically cleans dust adhering to the mesh portion of the filter 10.

次に、上下風向変更羽根８と左右風向変更羽根９と羽根ベース１５について説明する。 Next, the up/down wind direction changing blade 8, the left/right air direction changing blade 9, and the blade base 15 will be described.

図１に示すように、上下風向変更羽根８は上下２段に２つ設けられている。つまり、室内機１は、２つの上下風向変更羽根８を備えている。それぞれの上下風向変更羽根８は、短手方向の上流側に位置する軸部１２を備えている。軸部１２は本体２の吹出口６両端部分に軸支されている。そのため、上下風向変更羽根８は上下方向に回動自在である。図２に示すように、上下風向変更羽根８のうち、下側の上下風向変更羽根８の上面には、段部１３が備えられている。 As shown in FIG. 1, two vertical airflow direction changing vanes 8 are provided in upper and lower two stages. That is, the indoor unit 1 includes the two vertical airflow direction changing vanes 8. Each vertical wind direction changing blade 8 includes a shaft portion 12 located on the upstream side in the lateral direction. The shaft portion 12 is pivotally supported at both ends of the air outlet 6 of the main body 2. Therefore, the vertical airflow direction changing vane 8 is vertically rotatable. As shown in FIG. 2, a step portion 13 is provided on the upper surface of the lower vertical wind direction changing blade 8 of the vertical wind direction changing blades 8.

図４に示すように、段部１３は、上下風向変更羽根８の短手方向の上流側（軸部１２側）に位置する上流側の面１３ａと、上下風向変更羽根８の短手方向の下流側に位置する下流側の面１３ｂと、上流側の面１３ａと下流側の面１３ｂの間にあり二面と略垂直に交わる壁面とを有する。下流側の面１３ｂは、上流側の面１３ａと略水平に、上流側の面１３ａよりも低く位置している。また、下流側の面１３ｂは、上下風向変更羽根８の長手方向において、少なくとも左右風向変更羽根９を設けた部分が、上流側の面１３ａよりも低く位置している。 As shown in FIG. 4, the step portion 13 has an upstream surface 13 a located on the upstream side (shaft portion 12 side) in the lateral direction of the vertical airflow direction changing blade 8 and a lateral surface of the vertical airflow direction changing blade 8. It has a downstream surface 13b located on the downstream side, and a wall surface between the upstream surface 13a and the downstream surface 13b that intersects the two surfaces substantially perpendicularly. The downstream surface 13b is positioned substantially horizontally with the upstream surface 13a and lower than the upstream surface 13a. Further, in the downstream surface 13b, in the longitudinal direction of the vertical airflow direction changing blade 8, at least the portion provided with the horizontal airflow direction changing blade 9 is located lower than the upstream surface 13a.

図２に示すように、下側の上下風向変更羽根８は、下流側の面１３ｂに２つの左右風向変更羽根９を備えている。それぞれの左右風向変更羽根９は、１つずつ上下風向変更羽根８の両端部に回動可能に設けられている。なお、上下風向変更羽根８の両端部とは、上下風向変更羽根８の上面を長手方向に略３分割した場合に、両端に位置する２つの面である。 As shown in FIG. 2, the lower vertical wind direction changing vane 8 includes two horizontal wind direction changing vanes 9 on the downstream surface 13b. Each left and right wind direction changing blade 9 is rotatably provided at both ends of the up and down wind direction changing blade 8. The both ends of the vertical airflow direction changing blade 8 are two surfaces located at both ends when the upper surface of the vertical airflow direction changing blade 8 is divided into approximately three in the longitudinal direction.

左右風向変更羽根９は、羽根ベース１５を介して、上下風向変更羽根８に設けられている。羽根ベース１５は複数の羽根部材１４を軸支するための板状部材である。羽根ベース１５は２つあり、それぞれを上下風向変更羽根８に設けてある。また、羽根ベース１５の吹出口端部側は上下風向変更羽根８に回動自在に軸支され、羽根ベース１５における吹出口中央側端部が固定されない自由端とされている。そのため、図２に示すように、２つの羽根ベース１５はそれぞれ、吹出口中央側端部を手前に回動できる。 The left/right airflow direction changing blade 9 is provided on the up/down airflow direction changing blade 8 via the blade base 15. The blade base 15 is a plate-shaped member for pivotally supporting the plurality of blade members 14. There are two blade bases 15, and each of them is provided on the vertical wind direction changing blade 8. Further, the outlet end side of the blade base 15 is rotatably supported by the vertical airflow direction changing blade 8, and the outlet center side end of the blade base 15 is a free end that is not fixed. Therefore, as shown in FIG. 2, each of the two blade bases 15 can rotate toward the front end of the air outlet.

詳述すると、図５、図６に示すように、上下風向変更羽根８は、段部１３の下流側の面１３ｂにおいて吹出口端部側に設けられた軸受孔１７と、段部１３の下流側の面１３ｂの略中央部分に設けられたストッパー用孔１９と、段部１３の壁面に設けられた少なくとも１つの固定孔１２ａとを備えている。上流側の面１３ａにおいて、固定孔１２ａを設けた箇所には、上流側の面１３ａから略垂直方向に突出する膨らみを設けている。これにより、固定孔１２ａを設けた箇所の強度低下を防止できる。 More specifically, as shown in FIGS. 5 and 6, the vertical airflow direction changing vane 8 includes a bearing hole 17 provided on the downstream end surface 13 b of the step portion 13 on the outlet end side and a downstream side of the step portion 13. The stopper hole 19 is provided in a substantially central portion of the side surface 13b, and at least one fixing hole 12a is provided in the wall surface of the stepped portion 13. On the upstream surface 13a, a bulge is provided at a location where the fixing hole 12a is provided so as to project in a substantially vertical direction from the upstream surface 13a. As a result, it is possible to prevent the strength of the portion where the fixing hole 12a is provided from decreasing.

また、羽根ベース１５は、吹出口端部側に設けられた回転軸１６と、吹出口中央側端部に設けられたストッパーリブ１８と、吹出口中央側端部に設けられた把手部２０と、羽根ベース１５の上面から略垂直方向に突出する複数の軸１５ａと、羽根ベース１５の上流側の長手方向に位置する複数の固定突起部１２ｂ（図７に示す）とを有している。 Further, the blade base 15 includes a rotating shaft 16 provided on the blower outlet end side, a stopper rib 18 provided on the blower outlet central side end, and a handle portion 20 provided on the blower outlet central side end. The blade base 15 has a plurality of shafts 15a that project substantially vertically from the upper surface of the blade base 15, and a plurality of fixed protrusions 12b (shown in FIG. 7) located in the longitudinal direction on the upstream side of the blade base 15.

図５に示すように、回転軸１６は、羽根ベース１５の下面から略垂直方向に突出する軸である。回転軸１６は軸受孔１７に挿入可能である。回転軸１６を軸受孔１７に挿入して、係合部を中心に羽根ベース１５を回動自在としている。 As shown in FIG. 5, the rotating shaft 16 is a shaft that projects from the lower surface of the blade base 15 in a substantially vertical direction. The rotating shaft 16 can be inserted into the bearing hole 17. The rotary shaft 16 is inserted into the bearing hole 17 so that the blade base 15 is rotatable around the engaging portion.

ストッパーリブ１８は、羽根ベース１５の下面から略垂直方向に突出するリブである。図５において、ストッパーリブ１８は図示していないが、図６に示すように、ストッパーリブ１８は把手部２０の後ろに位置している。ストッパーリブ１８はストッパー用孔１９に挿入可能である。ストッパーリブ１８をストッパー用孔１９に挿入することで、羽根ベース１５を上下風向変更羽根８の上面に固定できる。さらに、固定孔１２ａは、図７に示す固定突起部１２ｂに嵌合することでも、羽根ベース１５を上下風向変更羽根８の上面に固定できる。これにより、通風路７等を掃除する際以外に、意図せず左右風向変更羽根９が手前に開かないように、左右風向変更羽根９を上下風向変更羽根８の上面に固定できる。把手部２０は、ストッパーリブ１８の手前に位置し、羽根ベース１５の上方略垂直方向に突出するように設けられた突出物である。把手部２０に指をかけて手前に引っ張ると、羽根ベース１５は回転軸１６と軸受孔１７の係合部を中心に回動する。把手部２０はスリット孔を有しており、空気調和機の運転時に吹出口６から吹き出された空気がスリット孔に流れるため、把手部２０に結露が生じにくくなる。 The stopper rib 18 is a rib that projects from the lower surface of the blade base 15 in a substantially vertical direction. Although the stopper rib 18 is not shown in FIG. 5, the stopper rib 18 is located behind the handle portion 20 as shown in FIG. The stopper rib 18 can be inserted into the stopper hole 19. By inserting the stopper rib 18 into the stopper hole 19, the blade base 15 can be fixed to the upper surface of the vertical airflow direction changing blade 8. Furthermore, the fixing hole 12a can be fixed to the upper surface of the vertical airflow direction changing blade 8 by fitting the fixing protrusion 12b shown in FIG. Thereby, the left/right airflow direction changing blade 9 can be fixed to the upper surface of the up/down airflow direction changing blade 8 so as not to unintentionally open the left/right airflow direction changing blade 9 except when cleaning the ventilation path 7 and the like. The handle portion 20 is a protrusion that is located in front of the stopper rib 18 and that protrudes above the blade base 15 in a substantially vertical direction. When a finger is put on the grip portion 20 and pulled toward the front, the blade base 15 rotates around the engaging portion between the rotary shaft 16 and the bearing hole 17. The handle portion 20 has a slit hole, and the air blown out from the air outlet 6 flows into the slit hole during the operation of the air conditioner, so that the handle portion 20 is less likely to cause dew condensation.

また、図３に示すように、軸受孔１７を軸部１２より手前に設けてある。そのため、上下風向変更羽根８を回動させて吹出口６を開いた際、左右風向変更羽根９の吹出口側端部を含むほぼ全体が通風路７の外側に位置し、通風路７内の掃除が容易になる。 Further, as shown in FIG. 3, a bearing hole 17 is provided in front of the shaft portion 12. Therefore, when the vertical airflow direction changing vane 8 is rotated to open the air outlet 6, almost the entire right and left airflow direction changing vane 9 including the air outlet side end is located outside the airflow passage 7 and inside the airflow passage 7. Easy to clean.

図６に示すように、各羽根部材１４は、吹出口６から吹き出された空気を整流する主面と、羽根部材１４の最下面に位置し主面と略垂直に位置するベース面と、ベース面の略中央に設けられた穴である軸受部２１と、主面の下部から下方略垂直方向に突出する軸であるピン軸２２ａと、ピン軸２２ａと対向する位置に設けられベース面から上方略垂直方向に突出する軸である連係ピン２２ｂを有している。 As shown in FIG. 6, each blade member 14 has a main surface for rectifying the air blown out from the air outlet 6, a base surface located at the lowermost surface of the blade member 14 and substantially perpendicular to the main surface, and a base. A bearing portion 21 which is a hole provided in the substantially center of the surface, a pin shaft 22a which is a shaft projecting from the lower part of the main surface in a substantially vertical direction downward, and a base surface which is provided at a position facing the pin shaft 22a It has a linking pin 22b that is a shaft that projects in a substantially vertical direction.

図７に示すように、連動アーム２３はスリット溝２４を有する板状部材である。スリット溝２４は、上下風向変更羽根８の長手方向に長い略楕円状の貫通孔である。 As shown in FIG. 7, the interlocking arm 23 is a plate-shaped member having a slit groove 24. The slit groove 24 is a substantially elliptical through hole that is long in the longitudinal direction of the vertical airflow direction changing blade 8.

図６、図７に示すように、軸受部２１に軸１５ａが挿入される。これにより、各羽根部材１４は左右方向に回動自在である。また、スリット溝２４にピン軸２２ａが挿入される。これにより、連動アーム２３を左右方向にスライドさせたとき、複数の羽根部材１４を同方向に統一できる。 As shown in FIGS. 6 and 7, the shaft 15 a is inserted into the bearing portion 21. As a result, each blade member 14 is rotatable in the left-right direction. Further, the pin shaft 22a is inserted into the slit groove 24. Thereby, when the interlocking arm 23 is slid in the left-right direction, the plurality of blade members 14 can be unified in the same direction.

さらに、図８、図９に示すように、左右風向変更羽根９は、羽根ベース１５の吹出口端部側に位置するレバーアーム２５、駆動アーム２７を備えている。レバーアーム２５は、上下風向変更羽根８の長手方向に長い略平板状の部材である。駆動アーム２７は、上下風向変更羽根８の長手方向に長い略棒状の部材である。レバーアーム２５における吹出口６中央側端部は、最も吹出口端部側に位置する羽根部材１４ａを介して連動アーム２３に連結されている。 Further, as shown in FIGS. 8 and 9, the left/right airflow direction changing blade 9 includes a lever arm 25 and a drive arm 27 located on the blower outlet end side of the blade base 15. The lever arm 25 is a substantially flat plate member that is long in the longitudinal direction of the vertical airflow direction changing blade 8. The drive arm 27 is a substantially rod-shaped member that is long in the longitudinal direction of the vertical airflow direction changing vane 8. The end of the lever arm 25 on the center side of the outlet 6 is connected to the interlocking arm 23 via the blade member 14a located closest to the end of the outlet.

図６に示すように、最も吹出口端部側に位置する羽根部材１４ａの連係ピン２２ｂは、レバーアーム２５における吹出口６中央側端部の一端に設けた係合孔２５ａに挿入されている。レバーアーム２５の吹出口端部側の他端は、駆動アーム２７における吹出口６中央側端部の一端に連結されている。駆動アーム２７の吹出口端部側の他端は、レバー３０を介して、モータ２６の軸に連結されている。レバー３０は、モータ２６の回転運動を駆動アーム２７の左右方向の運動に変換する部材である。尚、上記モータ２６は、図８、図９では上下風向変更羽根８に設けてあるように見えるが、本体２側に設けてある。 As shown in FIG. 6, the linking pin 22b of the blade member 14a located closest to the outlet end portion side is inserted into the engagement hole 25a provided at one end of the end portion of the lever arm 25 on the center side of the outlet port 6. .. The other end of the lever arm 25 on the outlet end side is connected to one end of the drive arm 27 on the center side end of the outlet 6. The other end of the drive arm 27 on the outlet end side is connected to the shaft of the motor 26 via a lever 30. The lever 30 is a member that converts the rotational movement of the motor 26 into the horizontal movement of the drive arm 27. It should be noted that the motor 26 is provided on the main body 2 side, although it appears to be provided on the vertical airflow direction changing blade 8 in FIGS. 8 and 9.

モータ２６の回転動作は、レバー３０により、駆動アーム２７の左右方向の動作に変換される。駆動アーム２７の左右方向の動作は、レバーアーム２５に伝達され、最も吹出口端部側に位置する羽根部材１４ａを左右方向に動作させるとともに、連動アーム２３を左右方向に動作させる。そして、連動アーム２３は、他の羽根部材１４の方向を最も吹出口端部側に位置する羽根部材１４ａの方向に揃えることができる。つまり、モータ２６の回転動作により、全ての羽根部材１４の方向を揃えることができる。 The rotation operation of the motor 26 is converted into a left-right operation of the drive arm 27 by the lever 30. The left-right movement of the drive arm 27 is transmitted to the lever arm 25 to move the blade member 14a located closest to the outlet end side in the left-right direction and the interlocking arm 23 in the left-right direction. Then, the interlocking arm 23 can align the direction of the other blade member 14 with the direction of the blade member 14a located closest to the outlet end side. That is, the rotation operation of the motor 26 can align the directions of all the blade members 14.

図８、図９に示すように、レバーアーム２５は、上下風向変更羽根８の長手方向に長い溝３１を備える平面部と、平面部から上下風向変更羽根８の回転軸方向に突出する連結アーム部２８を備えている。連結アーム部２８の先端には軸受が設けられている。 As shown in FIGS. 8 and 9, the lever arm 25 includes a flat portion having a groove 31 that is long in the longitudinal direction of the vertical airflow direction changing blade 8 and a connecting arm that projects from the flat surface portion in the rotational axis direction of the vertical airflow direction changing blade 8. The unit 28 is provided. A bearing is provided at the tip of the connecting arm portion 28.

駆動アーム２７は、上下風向変更羽根８の長手方向に長い棒状部と、棒状部における吹出口６中央側端部の一端に設けられレバー３０と接続するレバー接続部と、棒状部の中央側端部方向の他端から上下風向変更羽根８の回転軸方向に突出する駆動側連結アーム部２９とを備えている。駆動側連結アーム部２９の先端には、軸が設けられている。 The drive arm 27 includes a rod-shaped portion that is long in the longitudinal direction of the vertical airflow direction changing vane 8, a lever connection portion that is provided at one end of the end portion of the rod-shaped portion on the center side of the air outlet 6 and that is connected to the lever 30, and a center-side end of the rod-shaped portion. The drive-side connecting arm portion 29 is provided so as to project from the other end in the direction of the vertical axis of the vertical wind direction changing blade 8. A shaft is provided at the tip of the drive-side connecting arm portion 29.

駆動側連結アーム部２９の軸は、連結アーム部２８の軸受に挿入される。駆動側連結アーム部２９の軸は、連結アーム部２８の軸受内で、回転方向の動作は自在であり、左右方向の動作は規制される。駆動側連結アーム部２９の軸と連結アーム部２８の軸受の中心軸は、上下風向変更羽根８の軸部１２の中心軸と同軸上に位置する。これにより、上下風向変更羽根８が上下方向に回動しても、駆動側連結アーム部２９の軸と、連結アーム部２８の軸受との係合が外れることがない。 The shaft of the drive-side connecting arm portion 29 is inserted into the bearing of the connecting arm portion 28. The shaft of the drive-side connecting arm portion 29 is freely movable in the rotational direction within the bearing of the connecting arm portion 28, and the movement in the left-right direction is restricted. The axis of the drive-side connecting arm portion 29 and the central axis of the bearing of the connecting arm portion 28 are located coaxially with the central axis of the axial portion 12 of the vertical airflow direction changing vane 8. As a result, even if the vertical airflow direction changing blade 8 rotates in the vertical direction, the shaft of the drive-side connecting arm portion 29 and the bearing of the connecting arm portion 28 are not disengaged.

また、上下風向変更羽根８は、軸部１２の中心軸と同軸上に位置する部分に、ガイド凹部３２を備えている。本実施の形態では、ガイド凹部３２は、上下風向変更羽根８の短手方向上流側に設けられている。駆動側連結アーム部２９の軸と連結アーム部２８の軸受は、係合した状態で、ガイド凹部３２に挿入されている。さらに、レバーアーム２５の溝３１には、上下風向変更羽根８に設けた凸部が挿入されている。つまり、溝３１とガイド凹部３２によって、レバーアーム２５の左右方向以外の動作を規制しているので、レバーアーム２５の左右方向の動作を、円滑な動作にできる。 Further, the vertical airflow direction changing vane 8 is provided with a guide concave portion 32 in a portion located coaxially with the central axis of the shaft portion 12. In the present embodiment, the guide recess 32 is provided on the upstream side in the lateral direction of the vertical airflow direction changing blade 8. The shaft of the drive-side connecting arm portion 29 and the bearing of the connecting arm portion 28 are inserted into the guide recess 32 in an engaged state. Further, in the groove 31 of the lever arm 25, a convex portion provided on the vertical wind direction changing blade 8 is inserted. That is, since the groove 31 and the guide recess 32 restrict the movement of the lever arm 25 other than in the horizontal direction, the horizontal movement of the lever arm 25 can be performed smoothly.

次に、上記のように構成された空気調和機において、作用効果について説明する。 Next, the function and effect of the air conditioner configured as described above will be described.

本実施の形態に係る空気調和機は、空調運転を開始すると、上下風向変更羽根８が開制御されて吹出口６が開放される。さらに、送風ファン５が駆動することで、室内の空気が開口部２ａを介して室内機の内部に取り入れられる。取り入れられた空気は、熱交換器４で熱交換され、送風ファン５を通過し、送風ファン５の送風方向の下流側に形成された通風路７を通過して、吹出口６より吹き出される。吹出口６より吹き出される空気は、上下風向変更羽根８と左右風向変更羽根９によって風向を変え、室内を冷房もしくは暖房する。 In the air conditioner according to the present embodiment, when the air conditioning operation is started, the vertical airflow direction changing blade 8 is controlled to be opened, and the air outlet 6 is opened. Further, when the blower fan 5 is driven, the air in the room is taken into the inside of the indoor unit through the opening 2a. The taken-in air is heat-exchanged by the heat exchanger 4, passes through the blower fan 5, passes through the ventilation passage 7 formed on the downstream side of the blower fan 5 in the blowing direction, and is blown out from the outlet 6. .. The air blown out from the air outlet 6 changes the wind direction by the vertical wind direction changing blade 8 and the horizontal wind direction changing blade 9 to cool or heat the room.

左右風向変更羽根９は、下側の上下風向変更羽根８の上面に位置する。また、それぞれの上下風向変更羽根８は短手方向の上流側に軸部１２を備え、軸部１２は本体２の吹出口６の両端部分に軸支されているため、上下風向変更羽根８は上下方向に回動自在である。そのため、上下風向変更羽根８の開口に伴い、左右風向変更羽根９の奥側端部を含むほぼ全体が吹出口の下流に位置する。これにより、左右風向変更羽根が通風路に位置する従来のものに比べ、風路抵抗を低減できる。すなわち、吹出性能の低下を抑制できる。 The left/right airflow direction changing blade 9 is located on the upper surface of the lower up/down airflow direction changing blade 8. Further, since each vertical wind direction changing blade 8 is provided with the shaft portion 12 on the upstream side in the lateral direction, and the shaft portion 12 is axially supported by both end portions of the air outlet 6 of the main body 2, the vertical wind direction changing blade 8 is It is rotatable in the vertical direction. Therefore, with the opening of the up/down airflow direction changing blades 8, almost the entire area including the rear side end portions of the left/right airflow direction changing blades 9 is located downstream of the air outlet. As a result, the air passage resistance can be reduced compared to the conventional one in which the left and right airflow direction changing blades are located in the air passage. That is, it is possible to suppress the deterioration of the blowing performance.

また、本実施の形態では、通風抵抗となりやすい羽根ベース１５を、上下風向変更羽根８に形成した段部１３の下流側の面１３ｂに設けている。そのため、羽根ベース１５が上下風向変更羽根８から突出する寸法を減少、もしくは、なくすことができる。つまり、下側の上下風向変更羽根８の上面に沿って流れる空気の抵抗を少なくできる。これにより、上下風向変更羽根８に、左右風向変更羽根９の羽根ベース１５を設けたことにより生じる吹出性能の低下を抑制できる。 In addition, in the present embodiment, the blade base 15 that easily causes ventilation resistance is provided on the downstream surface 13b of the step portion 13 formed in the vertical airflow direction changing blade 8. Therefore, the dimension in which the blade base 15 projects from the vertical airflow direction changing blade 8 can be reduced or eliminated. That is, the resistance of the air flowing along the upper surface of the lower vertical wind direction changing vane 8 can be reduced. As a result, it is possible to suppress the deterioration of the blowing performance caused by providing the blade base 15 of the left/right airflow direction changing blade 9 on the up/down airflow direction changing blade 8.

一方、上下風向変更羽根８を手前に回動させて吹出口６を開口すれば、下側の上下風向変更羽根８の上面に設けてある左右風向変更羽根９が、吹出口６の前方に位置する。つまり、羽根ベース１５が通風路７の外に位置する。そして、羽根ベース１５の自由端部を手前に回動すると、通風路７を開放でき、通風路７内の掃除が容易になる。 On the other hand, if the vertical airflow direction changing vane 8 is rotated toward the front to open the air outlet 6, the horizontal airflow direction changing vane 9 provided on the upper surface of the lower vertical airflow direction changing vane 8 is positioned in front of the air outlet 6. To do. That is, the blade base 15 is located outside the ventilation path 7. Then, when the free end portion of the blade base 15 is turned to the front, the ventilation passage 7 can be opened, and the inside of the ventilation passage 7 can be easily cleaned.

また、羽根ベース１５を２つ設け、羽根ベース１５の手前への回動操作を、吹出口６の一端ではなく、上下風向変更羽根８の長手方向における略中央部分で行う。羽根ベース１５を１つで構成し、羽根ベース１５の一端部を上下風向変更羽根８に軸支し、他端を自由端として回動する構成としてもよいが、羽根ベース１５を１つで構成した場合、自由端が吹出口６の端部近傍に位置し、羽根ベース１５を手前側に回動させにくくなる。しかしながら、本実施の形態のように、羽根ベース１５が２つあり、それぞれの羽根ベース１５の吹出口端部側を上下風向変更羽根８に軸支し、自由端部を手前側に回動自在とすれば、吹出口６の略中央部分で羽根ベース１５を手前側へと回動できる。これにより、羽根ベース１５を１つ設けた場合よりも、羽根ベース１５を２つ設けた場合のほうが、通風路７内の掃除が容易になる。 Further, two blade bases 15 are provided, and the rotating operation of the blade bases 15 to the near side is performed not at one end of the outlet 6 but at a substantially central portion in the longitudinal direction of the vertical airflow direction changing blades 8. The blade base 15 may be configured as one, and one end of the blade base 15 may be pivotally supported by the vertical airflow direction changing blade 8 and the other end may be rotated as a free end, but the blade base 15 is configured as one. In this case, the free end is located in the vicinity of the end of the outlet 6, and it becomes difficult to rotate the blade base 15 to the front side. However, as in the present embodiment, there are two blade bases 15, the outlet end side of each blade base 15 is pivotally supported by the vertical airflow direction changing blade 8, and the free end is freely rotatable to the front side. Then, the blade base 15 can be turned to the front side at the substantially central portion of the air outlet 6. Accordingly, the inside of the ventilation passage 7 can be cleaned more easily when two blade bases 15 are provided than when one blade base 15 is provided.

また、羽根ベース１５における吹出口６中央側端部である自由端部には、把手部２０が設けてある。把手部２０を手前側に引っ張れば、ストッパーリブ１８がストッパー用孔１９から外れ、固定突起部１２ｂが固定孔１２ａから外れる。そのため、容易に羽根ベース１５を手前側に回動できる。 A handle portion 20 is provided at a free end portion of the blade base 15, which is an end portion on the center side of the outlet 6. When the grip portion 20 is pulled to the front side, the stopper rib 18 is disengaged from the stopper hole 19 and the fixing projection 12b is disengaged from the fixing hole 12a. Therefore, the blade base 15 can be easily rotated to the front side.

また、羽根ベース１５の吹出口端部側は、上下風向変更羽根８の軸部１２より手前側に上下風向変更羽根８の下流側の面１３ｂに軸支されている。よって、左右風向変更羽根９の羽根ベース１５は、上下風向変更羽根８を開いた時、左右風向変更羽根９の奥側端部を含むほぼ全体が通風路７の外側に位置する。そのため、羽根ベース１５の手前側への回動操作がしやすくなり、掃除が更に容易になる。 Further, the air outlet end side of the blade base 15 is pivotally supported on the surface 13b on the downstream side of the vertical airflow direction changing blade 8 in front of the shaft portion 12 of the vertical airflow direction changing blade 8. Therefore, when the vertical airflow direction changing blade 8 is opened, the blade base 15 of the leftward/rightward airflow direction changing blade 9 is located substantially entirely outside the ventilation passage 7 including the rear end portion of the left/right airflow direction changing blade 9. Therefore, the blade base 15 can be easily rotated to the front side, and cleaning can be further facilitated.

また、羽根ベース１５の吹出口端部側に設けた回転軸１６が、通風路７外に位置するため、回転軸１６と軸受孔１７の脱着が容易になる。そのため、左右風向変更羽根９の上下風向変更羽根８からの脱着が容易になり、掃除が更に容易になる。 Further, since the rotary shaft 16 provided on the blower outlet end side of the blade base 15 is located outside the ventilation passage 7, the rotary shaft 16 and the bearing hole 17 can be easily attached and detached. Therefore, the left/right airflow direction changing blade 9 can be easily attached/detached to/from the up/down airflow direction changing blade 8, and cleaning can be further facilitated.

以上、本発明に係る空気調和機について、実施の形態に基づいて説明したが、本発明は上記実施の形態に限られない。さらに、本発明の技術的思想の範囲を逸脱しない範囲で、空気調和機の構成に適宜変更を加えることは可能である。例えば、本実施の形態では室内機と室外機が別体となったセパレート型の空気調和機を例示して説明したが、室内機と室外機が一体化した一体型の空気調和機であってもよい。また、左右風向変更羽根９の羽根ベース１５は２つに分割したものを例示したが、１つであってもよい。つまり、本発明の範囲は、特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれるものである。 The air conditioner according to the present invention has been described above based on the embodiment, but the present invention is not limited to the above embodiment. Furthermore, it is possible to make appropriate changes to the configuration of the air conditioner without departing from the scope of the technical idea of the present invention. For example, although the present embodiment has been described by exemplifying the separate type air conditioner in which the indoor unit and the outdoor unit are separate bodies, it is an integrated air conditioner in which the indoor unit and the outdoor unit are integrated. Good. Further, the blade base 15 of the left/right airflow direction changing blade 9 is illustrated as being divided into two, but may be one. In other words, the scope of the present invention is defined by the claims, and includes meanings equivalent to the claims and all modifications within the scope.

本発明は、上記したように、本体通風路内の掃除がしやすく、吹出性能も良好な空気調和機を提供することができ、家庭用及び業務用の空気調和機に広く適用することができる。 INDUSTRIAL APPLICABILITY As described above, the present invention can provide an air conditioner that is easy to clean the inside of the air passage of the main body and has good blowing performance, and can be widely applied to household and commercial air conditioners. ..
