Abstract

A ceiling embedded type air conditioner that reduces short circuits without increasing drafts due to air currents blown out from outlets includes a casing and a fan. The casing includes a casing lower part formed by an alternating sequence of four panel side parts and four panel corner parts. The casing further includes four main outlet passageways along the panel side parts auxiliary outlet passageways in the three panel corner parts and an inlet so that is surrounded by all of the panel side parts. The auxiliary outlet passageways are formed so that the spacing between each auxiliary outlet passageways and a corresponding adjacent main outlet passageways satisfies a prescribed dimensional relationship.

Claims

1. An air conditioner embedded in the ceiling of an air conditioned room, comprising:

a casing including

a casing lower part formed by an alternating sequence of a plurality of side parts and a plurality of corner parts,

a plurality of side part outlets with one being disposed along each of said side parts,

a plurality of corner part outlets with one being disposed in at least one of said corner parts, and

an inlet surrounded by all of said side parts; and

a fan, disposed inside said casing, and configured to take air from said inlet into said casing, and blows said air from said side part outlets and said corner part outlets into said air conditioned room,

each of said corner part outlets and a corresponding one of said side part outlets adjacent to a corresponding one of said corner part outlets having a dimensional relationship there between of;

D/(L₁W₁+S₂)^0.5>

0.15

where D is a distance between a first proximate part, which is a most proximate part of each of said corner part outlets to a corresponding one of said side part outlets, and a second proximate part, which is a most proximate part of each of said side part outlets to a corresponding one of said corner part outlet, L₁ is a length of each of said side part outlets in a direction along an outer circumferential edge of each of said side parts, W₁ is a width of each of said side part outlets in a direction orthogonal to the outer circumferential edge of a corresponding one of said side parts, and S₂ is an opening area of each of said corner part outlets.

2. The air conditioner as recited in claim 1, wherein

said opening area of each of said corner part outlets is less than an opening area of each of said side part outlets.

3. The air conditioner as recited in claim 1, wherein

two of said side part outlets which are adjacent to each of said corner part outlets, are substantially mutually orthogonal to each other.

4. The air conditioner as recited in claim 3, wherein

each of said corner part outlet has a circumferential edge part formed so that an air current blown out from each of said corner part outlets is blown out in a direction away from an air current blown out from each of said two of said side part outlets.

5. The air conditioner as recited in claim 3, wherein

each of said corner part outlets has a guide flap configured to guide an air current from each of said corner part outlets, respectively, away from an air current blown out from each of said two of said side part outlets.

6. The air conditioner as recited in claim 2, wherein

two of said side part outlets which are adjacent to each of said corner part outlets, are substantially mutually orthogonal to each other.

7. The air conditioner as recited in claim 6, wherein

each of said corner part outlets has a circumferential edge part formed so that an air current blown out from each of said corner part outlets is blown out in a direction away from an air current blown out from each of said two of said side part outlets.

8. The air conditioner as recited in claim 6, wherein

each of said corner part outlets has a guide flap configured to guide an air current from each of said corner part outlets, respectively, away from an air current blown out from each of said two of said side part outlets.

9. The air conditioner as recited in claim 1, wherein

each of said corner part outlets has a circumferential edge part formed so that an air current blown out from each of said corner part outlets is blown out in a direction away from an air current blown out from each of said two of said side part outlets.

10. The air conditioner as recited in claim 1, wherein

each of said corner part outlets has a guide flap configured to guide an air current from each of said corner part outlets, respectively, away from an air current blown out from each of said two of said side part outlets.
