Description

【０００１】
【発明の属する技術分野】
本発明は、空気調和機に係わり、より詳細には、左右風向板群を回動自在に軸支するブッシュと、同左右風向板群を連結して駆動モータに連係するロッドとを吹出口に突出させることなく容易に組立できるようにし、前記駆動モータおよび前記ロッドを容易に且つ正確に連係できるようにし、また、前記ロッドを二分割し容易に組立できるようにして、製作、搬送および保管の管理等を容易にし、更に、前記ブッシュの軸孔に前記左右風向板群の支軸を容易に、且つ正確に挿入係止できるようにした構造に関する。
【０００２】
【従来の技術】
従来の空気調和機は、例えば図10（Ａ）および図10（Ｂ）と、図11とで示すように、本体１内の吸込口２と吹出口５とを結ぶ空気通路に、熱交換器３と送風ファン４とを設け、前記吹出口５の上面5aから垂下した支軸部で、上下および前後に支軸7aおよび8aを離間した二枚の上下風向板７および８を回動自在に軸支し、前記上面5aに設けた支軸孔5bでブッシュ９を保持し、同ブッシュ９により、左右風向板群６に設けられスリット6bを有する頭部付の支軸6aで回動自在に軸支し、前記左右風向板群６に設けられた連結ピン6cで連結板10を連結し、同連結板10により前記左右風向板群６を連動させてなる構成であった。
【０００３】
前記構成で、前記吸込口２から吸い込んだ空気を前記熱交換器３で熱交換し、前記左右風向板群６で左右方向の風向を調節し、前記上下風向板７および８で上下方向の風向を調節し、前記送風ファン４により前記吹出口５から室内に送出して空気調和を行っていた。
【０００４】
しかしながら、前記構成においては、前記連結ピン6cおよび前記連結板10が前記吹出口５に突出した構造であることから、同吹出口５において、前記連結ピン6cおよび前記連結板10による空気抵抗が生じて送風の効率が低下したり、騒音の原因になったり、または、露付の原因になってしまうなどの問題を有していた。
【０００５】
また、前記左右風向板群６を駆動モータ（図示せず）により駆動するようにした場合、図10で示すように、同駆動モータの駆動軸を嵌合する駆動軸孔14c を基端部に備え、先端部に連係ピン14a を備えた駆動リンク14によって、前記駆動モータの駆動軸と前記ブッシュ９に連係するために設けられ、前記連係ピン14a をスリット13c を有する連係孔13a を備えたロッド13に連係して前記左右風向板群６を駆動し回動していたが、前記連係ピン14a が前記連係孔13a のスリット13c から離脱してしまうという問題を有していた。
また、ブッシュ９の軸孔に前記左右風向板群６の頭部付の支軸6aを挿入係止する際、前記支軸6aを弾性変形させた時に前記スリット6bの上端が相互に干渉するため、前記支軸6aの頭部の外形を大きく形成して正確に挿入係止することができにくいという問題を有していた。
【０００６】
更に、前記ロッド13は、前記ブッシュ９を連結して前記左右風向板群６を回動する構成となり、同左右風向板群６および前記ブッシュ９が配設された前記吹出口５のほぼ全幅にわたる長さで製作する必要があることから、製作するための金型が高価なものになって、搬送や保管等の管理が容易でないという問題を有していた。
【０００７】
【発明が解決しようとする課題】
本発明においては、上記の問題点に鑑み、左右風向板群を回動自在に軸支するブッシュと、同左右風向板群を連結して駆動モータに連係するロッドとを吹出口に突出させることなく容易に組立できるようにし、前記駆動モータおよび前記ロッドを容易に且つ正確に連係できるようにし、また、前記ロッドを二分割し容易に組立できるようにして、製作、搬送および保管の管理等を容易にし、更に、前記ブッシュの軸孔に前記左右風向板群の支軸を容易に、且つ正確に挿入係止できるようにした空気調和機を提供することを目的とする。

BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner, and more specifically, a bush that pivotally supports a left and right wind direction plate group and a rod that connects the left and right wind direction plate group and is linked to a drive motor at an outlet. Making it easy to assemble without projecting, allowing the drive motor and the rod to be linked easily and accurately, and making the rod split in two and easy to assemble for production, transport and storage The present invention relates to a structure that facilitates management and the like, and further allows the support shafts of the left and right wind direction plate groups to be easily and accurately inserted and locked in the shaft hole of the bush.
[0002]
[Prior art]
For example, as shown in FIGS. 10 (A) and 10 (B) and FIG. 11, a conventional air conditioner is provided with a heat exchanger in an air passage connecting the suction port 2 and the outlet 5 in the main body 1. 3 and a blower fan 4 are provided, and two vertical airflow direction plates 7 and 8 with the support shafts 7a and 8a spaced apart in the vertical and front and rear directions are rotatable at a support shaft portion that hangs down from the upper surface 5a of the air outlet 5. The bush 9 is supported by a shaft hole 5b provided in the upper surface 5a. The bush 9 can be rotated by a support shaft 6a with a head provided in the left and right wind direction plate group 6 and having a slit 6b. The connection plate 10 is connected by a connecting pin 6 c provided on the left and right wind direction plate group 6 and the left and right wind direction plate group 6 is interlocked by the connection plate 10.
[0003]
In the above-described configuration, the air sucked from the suction port 2 is heat-exchanged by the heat exchanger 3, the left-right wind direction plate group 6 is used to adjust the left-right wind direction, and the upper-lower wind direction plates 7 and 8 are used to adjust the vertical wind direction. The air was conditioned by sending the air from the outlet 5 into the room by the blower fan 4.
[0004]
However, in the above configuration, since the connection pin 6c and the connection plate 10 protrude from the air outlet 5, air resistance is generated by the connection pin 6c and the connection plate 10 at the air outlet 5. As a result, the air blowing efficiency is reduced, causing noise, or causing dew.
[0005]
When the left and right wind direction plate group 6 is driven by a drive motor (not shown), as shown in FIG. 10, a drive shaft hole 14c for fitting the drive shaft of the drive motor is formed at the base end. A rod provided with a linkage hole 13a having a slit 13c, which is provided to be linked to the drive shaft of the drive motor and the bush 9 by a drive link 14 having a linkage pin 14a at the tip. Although the left and right wind direction plate group 6 is driven and rotated in conjunction with 13, there is a problem that the linkage pin 14 a is detached from the slit 13 c of the linkage hole 13 a.
Further, when the support shaft 6a with the head of the left and right wind direction plate group 6 is inserted and locked in the shaft hole of the bush 9, the upper ends of the slits 6b interfere with each other when the support shaft 6a is elastically deformed. There is a problem in that it is difficult to accurately insert and lock the outer shape of the head portion of the support shaft 6a.
[0006]
Further, the rod 13 is configured to connect the bush 9 and rotate the left and right wind direction plate group 6, and covers almost the entire width of the outlet 5 in which the left and right wind direction plate group 6 and the bush 9 are disposed. Since it is necessary to manufacture in length, the metal mold for manufacturing becomes expensive, and there is a problem that management such as transportation and storage is not easy.
