Description

  The present invention relates to a panel drive device that can open and close a suction port in a room of an air conditioner.

  In recent years, in order to improve the design of an air conditioner, an air conditioner in which the front surface of the air conditioner has a panel configuration has become widespread. This type of air conditioner has a panel drive device inside, and drives the panel forward to ensure ventilation performance when operating (see, for example, Patent Document 1).

  18 and 19 show a panel drive device for a conventional air conditioner described in Patent Document 1. FIG. As shown in the figure, the air conditioner includes a heat exchanger 2, a blower 3, a ventilation passage 11, and the like, and a movable panel 5 and a fixed panel 6 in the front. The movable panel 5 and the fixed panel 6 are coupled by a link mechanism 9, and the movable panel 5 moves back and forth by the operation of the link mechanism 9. A transmission gear 8 is provided at the upper end of the link mechanism 9 on the fixed panel 6 side, and a gear shape is formed below the transmission gear 8. On the other hand, a drive motor and a drive gear 7 are provided on the heat exchanger 2 side, and the drive gear 7 and the transmission gear 8 are meshed.

  Further, the drive shaft support member 31 on the back surface of the fixed panel 6, the upper end of the link mechanism 9 on the fixed panel 6 side, and the upper portion of the transmission gear 8 are communicated by the drive shaft 16.

When the drive motor is energized, the drive gear 7 operates, and the link mechanism 9 is operated by the movement of the transmission gear 8, and the movable panel 5 is moved forward.
