In the present invention, a pair of drive means 61 and 62 for driving the pair of horizontal blades 1 and 2 are provided. The pair of driving means 61 and 62 is configured such that, when the use of the indoor unit is finished, after the one driving means 61 that drives the one horizontal blade 1 is driven, the other horizontal blade 2 closes the one horizontal blade 1. It is possible to adopt a configuration in which the other driving means 62 that drives the other horizontal blade 2 is driven so as to push it back.
また、前記構成を採用した場合には、前記駆動手段６１，６２としてステッピングモータを採用することができる。

In the present invention, the pair of horizontal blades 1 and 2 is composed of a pair of upper and lower horizontal blades 1 and 2. The pair of horizontal blades 1 and 2 are provided so that the inner surface of the upper end portion of the lower horizontal blade 1 and the outer surface of the lower end portion of the upper horizontal blade 2 are in contact with each other at the closed position.

この発明の空気調和機の室内機では、室内機使用終了すると、一方の水平羽根１が閉塞位置よりも他方の水平羽根２側に位置するように回動し、他方の水平羽根２が、一方の水平羽根１を閉塞位置まで押し戻すように回動することで、一対の水平羽根１、２によって閉塞状態が得られることになる。このため、この閉塞状態においては、一対の水平羽根１、２同士が互いに他方側に押し合う状態となっている。したがって、一方の水平羽根１側に多少のバックラッシュ等が生じたとしても、一対の水平羽根１、２同士は接触状態を維持することができる。これにより、一対の水平羽根１、２の間に隙間を生じさせることがなく、室内機の外観上の美観を向上させることができる。
In the indoor unit of the air conditioner according to the present invention, when the use of the indoor unit ends, one horizontal blade 1 rotates so as to be positioned closer to the other horizontal blade 2 than the closed position, and the other horizontal blade 2 By rotating the horizontal blade 1 back to the closed position, a closed state is obtained by the pair of horizontal blades 1 and 2. For this reason, in this closed state, the pair of horizontal blades 1 and 2 are in a state of pressing against each other. Therefore, even if some backlash or the like occurs on one horizontal blade 1 side, the pair of horizontal blades 1 and 2 can maintain a contact state. Thereby, a space | gap is not produced between a pair of horizontal blade | wings 1 and 2, but the beauty | look on the external appearance of an indoor unit can be improved.
また、室内機使用終了時において、一方の水平羽根１を駆動する一方の駆動手段６１が駆動した後に、前記他方の水平羽根２を駆動する他方の駆動手段６２が前述のごとく駆動するように制御される一対の駆動手段６１，６２を備えることによって、一対の駆動手段６１，６２のみの簡単な構成で上記発明の水平羽根１、２の回動を容易に制御することができる。また、駆動手段６１，６２としてステッピングモータを採用することにより、廉価な装置で本発明を実施することができる。また、仮に、ステッピングモータの停止状態において、ステッピングモータに設けられているあそび部分により、一方の水平羽根１側のステッピングモータが１ステップ分だけ逆転しても、水平羽根１、２同士が押し合う状態で閉塞状態が得られているため、一対の水平羽根１、２の間に隙間を生じさせないようにすることができる。
Further, at the end of use of the indoor unit, control is performed such that after one driving means 61 for driving one horizontal blade 1 is driven, the other driving means 62 for driving the other horizontal blade 2 is driven as described above. By providing the paired drive means 61 and 62, the rotation of the horizontal blades 1 and 2 of the present invention can be easily controlled with a simple configuration of only the pair of drive means 61 and 62. Further, by employing stepping motors as the driving means 61 and 62, the present invention can be implemented with an inexpensive apparatus. Further, if the stepping motor is stopped, the horizontal blades 1 and 2 are pressed against each other even if the stepping motor on one horizontal blade 1 is reversed by one step due to the play portion provided in the stepping motor. Since the closed state is obtained in the state, it is possible to prevent a gap from being generated between the pair of horizontal blades 1 and 2.
また、本発明にあっては、前記一対の水平羽根１、２は、上下一対の水平羽根１、２から構成されている。また、前記一対の水平羽根１、２は、閉塞位置において、下方の水平羽根１の上端部の内面と、上方の水平羽根２の下端部の外面とが接触するように設けられている。さらに、前記一対の水平羽根１、２は、室内機使用終了時において、下方の水平羽根１の上端部が下方の水平羽根１の閉塞位置よりも上方に位置するように回動し、その後、上方の水平羽根２が前記下方の水平羽根１を下方の水平羽根１の閉塞位置まで押し戻すように設けられている。このような構成が採用された場合、上下一対の水平羽根１、２の間に隙間が生じず、室内機の外観上の美観を向上させることができる。つまり、室内機使用終了すると、下方の水平羽根１の上端部が閉塞位置よりも上方に位置するように回動し、上方の水平羽根２が下方の水平羽根１を閉塞位置まで押し戻すように回動することにより、上下一対の水平羽根１、２同士が互いに他方側に押し合う状態で閉塞状態が得られる。このため、一方の水平羽根１側に多少のバックラッシュ等が生じたとしても、一対の水平羽根１、２同士は接触状態を維持することができる。

Specifically, in the closed position, the pair of upper and lower horizontal blades 1 and 2 are provided such that the inner surface of the upper end portion of the lower horizontal blade 1 and the outer surface of the lower end portion of the upper horizontal blade 2 are in contact with each other. Yes.
また、制御部６０は、室内機使用終了時において、水平羽根が以下のような動作を行うようにステッピングモータ６１，６２を制御している。室内機使用終了時において、まず、下方の水平羽根１は、その上端部が閉塞位置よりも上方に位置するように回動して停止する（図１（ｂ）参照）。次に、上方の水平羽根２が、回動し、前述のように上端部が閉塞位置よりも上方に位置する下方の水平羽根１と当接して、下方の水平羽根１を閉塞位置まで押し戻す。そして、上下一対の水平羽根１、２がそれぞれの閉塞状態に位置した後に、水平羽根１、２の回動が停止する（図１（ｃ）参照）。
In addition, the control unit 60 controls the stepping motors 61 and 62 so that the horizontal blades perform the following operation when the indoor unit has been used. At the end of use of the indoor unit, first, the lower horizontal blade 1 is rotated and stopped so that the upper end portion thereof is located above the closed position (see FIG. 1B). Next, the upper horizontal blade 2 rotates, and as described above, the upper end portion comes into contact with the lower horizontal blade 1 positioned above the closed position, and pushes the lower horizontal blade 1 back to the closed position. Then, after the pair of upper and lower horizontal blades 1 and 2 are positioned in their closed states, the rotation of the horizontal blades 1 and 2 stops (see FIG. 1C).
本実施形態の室内機は、上記構成からなるため、上下一対の水平羽根１、２同士が互いに他方側に押し合う状態で閉塞状態が得られる。すなわち、下方の水平羽根１と上方の水平羽根２とが力を及ぼし合う状態で保持されることになるので、上下一対の水平羽根１、２には重力の影響が及びにくい状態となっている。また、下方の水平羽根１と上方の水平羽根２とが力を及ぼし合う状態では、ステッピングモータ６１，６２に設けられているあそび部分による下方の水平羽根１の戻りや多少のバックラッシュ等が生じたとしても、一対の水平羽根１、２同士は接触状態を維持することができる。このため、上下一対の水平羽根１、２の間に隙間が生じず、室内機の外観上の美観を向上させることができる。また、下側の水平羽根１は、上側の水平羽根２よりも斜め下方から使用者の目に留まり易い部分であるため、この部分の回動を防止することによって、外観品質を大きく向上することができる。
Since the indoor unit of the present embodiment has the above-described configuration, the closed state is obtained in a state in which the pair of upper and lower horizontal blades 1 and 2 are pressed against each other. That is, since the lower horizontal blade 1 and the upper horizontal blade 2 are held in a state of exerting force, the pair of upper and lower horizontal blades 1 and 2 are hardly affected by gravity. . Further, in a state where the lower horizontal blade 1 and the upper horizontal blade 2 exert force, the lower horizontal blade 1 is returned by the play portion provided in the stepping motors 61 and 62, or some backlash occurs. Even so, the pair of horizontal blades 1 and 2 can be kept in contact with each other. For this reason, a gap is not generated between the pair of upper and lower horizontal blades 1 and 2, and the appearance of the indoor unit can be improved. Moreover, since the lower horizontal blade | wing 1 is a part which is easy to catch a user's eye from diagonally downward rather than the upper horizontal blade | wing 2, the appearance quality is improved greatly by preventing the rotation of this portion. Can do.
また、一対のステッピングモータ６１，６２によって上記の動作を行うことができるため、簡単な構成で且つ廉価で上記利点を奏することが可能となる。
In addition, since the above-described operation can be performed by the pair of stepping motors 61 and 62, the above-described advantages can be achieved with a simple configuration and at a low price.
