A ceiling-embedded air conditioner includes: a ceiling-embedded casing main body that includes inside thereof a turbo fan and a heat exchanger disposed to surround the outer periphery of the turbo fan; a decorative panel that is mounted on a bottom surface of the casing main body and has an air blowoff opening; a drain pan that is provided on the bottom surface of the casing main body; an air blowoff path that is a through hole with rectangular cross section, the air blowoff path being provided in the drain pan and guiding conditioned air heat-exchanged by the heat exchanger to the air blowoff opening; and a reinforcement support column that is provided between long sides of the air blowoff path and includes a portion protruding more upward than an opening surface of the air blowoff path on an inflow side.
First claim
Opening claim text (preview).
What is claimed is: 1 . A ceiling-embedded air conditioner comprising: a ceiling-embedded casing main body that includes inside thereof a turbo fan and a heat exchanger disposed to surround the outer periphery of the turbo fan; a decorative panel that is mounted on a bottom surface of the casing main body and has an air blowoff opening; a drain pan that is provided on the bottom surface of the casing main body; an air blowoff path that is a through hole with rectangular cross section, the air blowoff path being provided in the drain pan and guiding conditioned air heat-exchanged by the heat exchanger to the air blowoff opening; and a reinforcement support column that is provided between long sides of the air blowoff path and includes a portion protruding more upward than an opening surface of the air blowoff path on an inflow side. 2 . The ceiling-embedded air conditioner according to claim 1 , wherein the support column is formed in an arch shape and has inclined portions extending from the long sides as base end portions to the center in an obliquely upward direction and has a peak portion connecting ends of the inclined portions, and the peak portion is positioned more upward than the opening surface of the air blowoff path on the inflow side. 3 . The ceiling-embedded air conditioner according to claim 1 , wherein the drain pan includes a foamed resin drain pan main body and a resin drain sheet formed integrally with the drain pan main body on the heat exchanger side, and the support column is formed as part of the drain sheet. 4 . The ceiling-embedded air conditioner according to claim 2 , wherein the drain pan includes a foamed resin drain pan main body and a resin drain sheet formed integrally with the drain pan main body on the heat exchanger side, and the support column is formed as part of the drain sheet.
