Abstract

In order to quickly condition a room by blowing conditioned air from an air blowing opening over a wide range, a fixed air blowing portion 75 is disposed at a central portion in a raised portion 740 in which a part of a decorative panel 70 is raised toward the air conditioning room. Movable air blowing portions 77 are disposed on both sides thereof. The movable air blowing portion 77 is rotatable within a predetermined angle range around an axis orthogonal to the panel surface of the decorative panel 70 or to the ceiling surface, while air blowing openings 754 and 783 are formed on each side surface of the fixed air blowing portion 75 and the movable air blowing portion 77. As a result, the conditioned air is blown out in a wide range in the horizontal direction from the air blowing opening 783 as the movable air blowing portion 77 rotates.

First claim

The invention claimed is:

1. A ceiling-embedded air conditioner, comprising:
a box-shaped main unit that includes an air blower and a heat exchanger and is disposed in a ceiling back space of an air conditioned room; and
a decorative panel that is attached to a bottom surface of the main unit along a ceiling surface of the air conditioned room, the decorative panel being provided with an air intake disposed on an air suction side of the air blower and an air outlet disposed on an air sending side of the air blower,
wherein the air outlet includes a raised portion in which a part of the decorative panel is raised toward the air conditioned room, the raised portion is formed with a fixed air blowing portion and movable air blowing portions disposed on both left and right sides, the movable air blowing portions are rotatable only within a predetermined angle range about an axis orthogonal to a panel surface of the decorative panel or the ceiling surface, a first air blowing opening is provided on a side surface of the fixed air blowing portion, and a second air blowing opening is provided on a side surface of each of the movable air blowing portions, and a conditioned air is blown out from the fixed air blowing portion and the movable air blowing portions along the panel surface, and
wherein the first air blowing opening of the fixed air blowing portion is opened toward a specific side of the decorative panel, and each of the movable air blowing portions are restricted to rotate about the axis only between a first position where the second air blowing opening faces the specific side of the decorative panel and a second position where the second air blowing opening faces another side adjacent to the specific side.

2. The ceiling-embedded air conditioner according to claim 1 ,
wherein the first air blowing opening and the second air blowing openings are aligned linearly when the movable air blowing portions are at the specific side of the decorative panel.
