Description

本発明は変動可能な腕部を介して制御される上下風向変更羽根を有する空気調和機の室内ユニットに関するものである。   The present invention relates to an indoor unit of an air conditioner having up and down airflow direction changing blades controlled via a variable arm portion.

従来、この種の空気調和機の室内ユニットは、本体前面の吸込口を開閉するパネルと、吹き出し口に配置される上下風向変更羽根とを有し、本体前面の吸込口の吹き出し口側に中羽根を設け、パネル周辺から吸込口に流入する空気流れを中羽根の動作によって制御し、特に、冷気を上方向に吹き出した際に、その冷気を空気調和機が直接吸い込むこと（ショートサーキット）を防ぐために、中羽根を、その上端部が本体前面の吸込口から離間する方向に動作させている。   Conventionally, an indoor unit of this type of air conditioner has a panel that opens and closes a suction port on the front surface of the main body, and a vertical airflow direction changing vane that is disposed in the blowout port. The blades are provided and the air flow from the periphery of the panel to the suction port is controlled by the operation of the middle blades. Especially when the cold air is blown upward, the air conditioner directly sucks the cold air (short circuit). In order to prevent this, the middle blade is operated in a direction in which the upper end portion is separated from the suction port on the front surface of the main body.

図６は、特許文献１に記載された従来の空気調和機の室内ユニットの水平吹出状態を示す横断面図である。図６に示すように、空気調和機の室内ユニットの本体１は、本体前面の吸込口１１を開閉するパネル３と、吹き出し口１０に配置される上下風向変更羽根９とを有し、本体前面の吸込口１１の吹き出し口１０側に中羽根６を有し、上下風向変更羽根は変動可能な腕部８を介して制御されている。

Moreover, since the blowing is narrowed, the wind speed that blows out increases, and the reachability is improved.

以下、本発明の各実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は、本発明の第１の実施の形態における空気調和機の室内ユニット外観斜視図を示す。図１において、本体１は台枠２とこの台枠２の前方に取り付けられた前面カバー３とからなり、台枠２および前面カバー３の上部には、吸い込みグリル４が設けられている。 (Embodiment 1)
FIG. 1 is an external perspective view of an indoor unit of an air conditioner according to a first embodiment of the present invention. In FIG. 1, the main body 1 includes a frame 2 and a front cover 3 attached to the front of the frame 2, and a suction grill 4 is provided on the frame 2 and the front cover 3.

前面カバー３及び吸い込みグリル４で覆われている吸込口から室内空気を吸込み、本体１内部で熱交換した後、吹き出し口１０から空調風として室内へ吹き出す。   The room air is sucked from the suction port covered with the front cover 3 and the suction grill 4, and heat is exchanged inside the main body 1.

図２は、図１のＡ−Ａ断面における本発明の第１の実施の形態における吹き出し口付近の要部拡大断面図を示す。図２において、空気調和機の本体１の吹き出し口１０はスタビライザ５とリアガイダ７、そして上下風向変更羽根９、上下風向変更羽根９を先端に保持する腕部８などより成り立っている。また、熱交換器と送風ファン、および左右方向風向変更羽根や熱交換温度検出器、マイクロコンピュータなども空気調和機１の構成要素となっている。   FIG. 2 shows an enlarged cross-sectional view of the main part near the outlet in the first embodiment of the present invention in the AA cross section of FIG. In FIG. 2, the air outlet 10 of the main body 1 of the air conditioner includes a stabilizer 5, a rear guider 7, an up / down air direction changing blade 9, and an arm portion 8 that holds the up / down air direction changing blade 9 at the tip. In addition, a heat exchanger, a blower fan, a left / right air direction changing blade, a heat exchange temperature detector, a microcomputer, and the like are constituent elements of the air conditioner 1.

図２に示されるように、空気調和機の運転時にリアガイダ７上部に搭載された中羽根６がスタビライザ５の延長となるよう配置する構成としている。これにより、中羽根６がスタビライザ５の働きをするためにスタビライザ５の見かけ上の長さが長くなり、吹き出し口１０より吹き出る風の動圧回収が容易となる。このため、送風性能を向上させることが出来る。さらに図２に示すように、変動可能な腕部８を介した上下風向変更羽根９をリアガイダ７の延長となるよう配置することにより、あたかも吹き出し口１０全体が長くなったかのような形状となり、スタビライザ５のみならずリアガイダ７でも動圧回収が可能となるため、送風性能をさらに向上させることが可能となる。なお、中羽根６および上下風向変更羽根９、スタビライザ５の形状は問わない。   As shown in FIG. 2, the middle blade 6 mounted on the upper part of the rear guider 7 is arranged to be an extension of the stabilizer 5 when the air conditioner is in operation. Thereby, since the middle blade 6 functions as the stabilizer 5, the apparent length of the stabilizer 5 is increased, and the dynamic pressure recovery of the wind blown from the blowout port 10 is facilitated. For this reason, ventilation performance can be improved. Furthermore, as shown in FIG. 2, by arranging the up-and-down wind direction changing blade 9 via the variable arm portion 8 so as to be an extension of the rear guider 7, it becomes a shape as if the entire outlet 10 becomes long, and the stabilizer. Since not only 5 but also the rear guider 7 can recover the dynamic pressure, the air blowing performance can be further improved. In addition, the shape of the middle blade | wing 6, the up-and-down wind direction change blade | wing 9, and the stabilizer 5 is not ask | required.

（実施の形態２）
図３、図４は、図１のＡ−Ａ断面における本発明の第２の実施の形態における吹き出し口付近の要部拡大断面図を示す。図３に示されるように、空気調和機の運転時にリアガイダ７上部に搭載された中羽根６がスタビライザ５の延長線上より下方に向けて配置されて
いる。このような形状とすることにより、この中羽根６が吹き出し口１０からスタビライザ５に沿って流れ出る風を下方向に押し付けるため、下向きの気流を生み出すことが容易となる。これは特に暖房時において足元に気流が届きやすくなるため有効である。 (Embodiment 2)
3 and 4 are enlarged cross-sectional views of the main part in the vicinity of the air outlet in the second embodiment of the present invention in the AA cross section of FIG. As shown in FIG. 3, the middle blade 6 mounted on the upper part of the rear guider 7 during operation of the air conditioner is arranged downward from the extension line of the stabilizer 5. By adopting such a shape, the middle blade 6 presses the wind flowing out from the blowout port 10 along the stabilizer 5 downward, so that it becomes easy to generate a downward airflow. This is particularly effective because airflow easily reaches the feet during heating.

また、図４に示されるように、その中羽根６の先端につながる形で上下風向変更羽根９を配置することにより、この下向き気流をさらに作りやすいものとすることが出来る。また、この両方の羽根６、９をスタビライザ５の略同一平面上となるように配置した場合には、動圧回収効果が高くなるために送風性能を向上させることが出来る。   Further, as shown in FIG. 4, by arranging the up / down airflow direction changing blade 9 so as to be connected to the tip of the middle blade 6, this downward airflow can be made easier. Further, when both of the blades 6 and 9 are arranged so as to be substantially on the same plane of the stabilizer 5, the dynamic pressure recovery effect is enhanced, so that the blowing performance can be improved.

（実施の形態３）
図５は、図１のＡ−Ａ断面における本発明の第３の実施の形態における吹き出し口付近の要部拡大断面図を示す。図５に示されるように、中羽根６と上下風向変更羽根９のそれぞれの弦が平行もしくは下流に行くほど小さくなるよう配置することにより、吹き出る空気が絞られ、まとまった気流として吹き出すことが可能となる。このような形状では、特定の箇所を狙うスポット気流としての効果が高くなる。また、空気を絞るため、吹き出る風速も大きくなるために、到達性も向上する。さらに、中羽根を可動可能な腕を解する構成とすることにより、特にこの中羽根６が湾曲した形状であるときに、運転状況により上に凸もしくは下に凸と変更することが出来るため、風向制御の幅が広がる。 (Embodiment 3)
FIG. 5 shows an enlarged cross-sectional view of the main part near the outlet in the third embodiment of the present invention in the AA cross section of FIG. As shown in FIG. 5, by arranging the chords of the middle blade 6 and the up / down airflow direction changing blade 9 to be parallel or downstream, the blown air can be throttled and blown out as a united air flow. It becomes. In such a shape, the effect as a spot air current aiming at a specific part becomes high. In addition, since the air is squeezed out, the wind speed that blows out increases, so that the reachability is improved. Furthermore, by adopting a configuration that disengages the movable arm of the middle blade, especially when the middle blade 6 has a curved shape, it can be changed to convex upward or downward depending on the driving situation. Expands the range of wind direction control.

以上のように、本発明にかかる空気調和機の室内ユニットは、送風性能の高効率化および風向性能を向上させることが可能となるので、軸流式の送風機等の用途にも適用できる。   As described above, since the indoor unit of the air conditioner according to the present invention can improve the air blowing performance and improve the wind direction performance, it can also be applied to applications such as an axial flow fan.
