Ceiling-embedded air conditioner with movable air blowing portions
A recently granted patent (Publication Number: US11767989B2) describes a ceiling-embedded air conditioner that offers improved air distribution and aesthetics. The air conditioner consists of a main unit, which includes an air blower and a heat exchanger, and a decorative panel that is attached to the bottom surface of the main unit along the ceiling surface of the room.
The decorative panel features an air suction part on the air blower's suction side and an air blowing part on the air sending side. The air blowing part includes a raised portion with an elliptical shape in plan view, where a section of the decorative panel is raised towards the room. This raised portion has a fixed air blowing portion in the center and movable air blowing portions on both sides. Each movable air blowing portion is a truncated cone-shaped rotation unit that can rotate about an axis orthogonal to the panel surface or the ceiling surface.
The fixed air blowing portion has a first air blowing opening on its side surface, while the rotation units have a second air blowing opening on their side surfaces. Conditioned air is blown out from both the fixed air blowing portion and the second air blowing opening along the panel surface. The patent also mentions the provision of dummy flaps on both sides of the first air blowing opening to create a sense of continuity with the second air blowing opening.
The patent further describes the rotation units of the movable air blowing portions having two positions: a first position where the second air blowing opening faces a specific side of the decorative panel, and a second position where it faces another side adjacent to the specific side. When the rotation unit is in the first position, the first and second air blowing openings are arranged in a straight line.
The patent emphasizes that the top surface of the fixed air blowing portion and each rotation unit are always in the same plane, ensuring a visually pleasing appearance. Additionally, the provision of dummy flaps on both sides of the first air blowing opening enhances the sense of continuity with the second air blowing opening.
Overall, this granted patent introduces a ceiling-embedded air conditioner that combines efficient air distribution with an aesthetically pleasing design. The incorporation of movable air blowing portions and the use of dummy flaps contribute to improved airflow and a seamless appearance.
