Abstract
A variable grille apparatus controls a flow rate of air circulated through the grille. Commercial properties are improved through an advanced opening and closing operation during adjustment of the air flow rate. The opening and closing operation of the grille is diversified, such as by sequential or simultaneous operation, so that the sense of operation is enhanced, an exterior design is diversified, and the air flow is secured through an optimization of the structural arrangement.
Claims16
A variable grille apparatus comprising:
- a housing with an open space;
- a flap that is movably mounted to the housing and configured to tilt when moving relative to the housing to open and close the open space of the housing according to a tilting position;
- and
- a drive unit including
- a connecting link connected to the flap,
- a rotating plate to which the connecting link is connected, and
- a driving motor for providing rotational power to the rotating plate,
- wherein a guide part is provided on the rotating plate and configured to guide movement of the connecting link during a rotation of the rotating plate,
- wherein the drive unit is configured to move a position of the flap when the connecting link moves rectilinearly along the guide part during the rotation of the rotating plate, and
- wherein the flap is mounted to the housing via a movable shaft, wherein guide holes are provided at upper and lower ends of the housing, respectively, allowing opposite ends of the movable shaft to be mounted thereto, respectively, and wherein the guide holes are configured to provide a moving path for the movable shaft.
