The drainage port 3Ba of thegutter 3B is arranged fronter than theupward protrusion 13D since the drainage port 3Ba is arranged fronter than the downward protrusion 3Bc. Further, thecontact plate 13E of thedrainage drain pan 13 is arranged below the drainage port 3Ba of thegutter 3B. - In such a configuration, as illustrated by arrowed line α in
FIG. 2 , the water in the mainbody drain pan 3A of themain body unit 3 is fed from the rear side to the front side with respect to thedrainage drain pan 13 of theoutlet assembly 9 from the drainage port 3Ba by going along thegutter 3B, and is discharged to outside of theair conditioner 1 via thedrainage hose 13A from thisdrainage drain pan 13. - The
air conditioner 1 of this embodiment includes: themain body unit 3, which has the mainbody drain pan 3A provided correspondingly to the heat exchanger 6; thedrainage drain pan 13, to which thedrainage hose 13A arranged below themain body unit 3 and connected with the outside is connected; and thegutter 3B which is formed to be connected with the mainbody drain pan 3A and which feeds the water of the mainbody drain pan 3A to the front side from the rear side with respect to thedrainage drain pan 13; the downward protrusion 3Bc is provided on a lower side of thegutter 3B; theupward protrusion 13D to be engaged with the downward protrusion 3Bc is provided at an inside bottom portion of thedrainage drain pan 13; and the drainage port 3Ba of thegutter 3B is arranged anterior to the downward protrusion 3Bc and theupward protrusion 13D in thedrainage drain pan 13. - According to this
air conditioner 1, positioning between themain body unit 3 and thedrainage drain pan 13 is able to be achieved by the engagement, at the inside bottom portion of thedrainage drain pan 13, between the downward protrusion 3Bc and theupward protrusion 13D. By the drainage port 3Ba of thegutter 3B being arranged anterior to these downward protrusion 3Bc andupward protrusion 13D engaging with each other at the inside bottom portion of thedrainage drain pan 13 in thedrainage drain pan 13, the water fed from the drainage port 3Ba of thegutter 3B to thedrainage drain pan 13 is guided anterior to the engaged portion for positioning between themain body unit 3 and thedrainage drain pan 13 in thedrainage drain pan 13. Therefore, the water fed from the drainage port 3Ba of thegutter 3B to thedrainage drain pan 13 is able to be prevented from going along the engaged portion for positioning between themain body unit 3 and thedrainage drain pan 13 and leaking out from thedrainage drain pan 13. - As illustrated in
FIG. 5 , in the conventional air conditioner, the drainage port 103Ba of thegutter 103B is bent downward, and amain body unit 103 is assembled with thedrainage drain pan 113 with a reverse side of the drainage port 103Ba put on theouter edge 113C of thedrainage drain pan 113. Therefore, when water is collected in thedrainage drain pan 113 and reaches up to the drainage port 103Ba of thegutter 103B, the water may rise and leak out from thedrainage drain pan 113 due to the capillary action between the reverse side of thegutter 103B and theouter edge 113C of thedrainage drain pan 113. Theair conditioner 1 of this embodiment is able to solve this problem. - Moreover, according to the
air conditioner 1 of this embodiment, by the drainage port 3Ba of thegutter 3B being arranged anterior to than the downward protrusion 3Bc and theupward protrusion 13D in thedrainage drain pan 13, as illustrated inFIG. 4 , the downward protrusion 3Bc to be engaged with thedrainage drain pan 13 is able to be formed with a width W2 smaller than a width W1 of thegutter 3B. Conventionally, as illustrated inFIG. 5 , since thegutter 103B is put on theouter edge 113C of thedrainage drain pan 113, a dimension has to be ensured to put thegutter 103B on theouter edge 113C so as to prevent a water leakage from a side portion of thegutter 103B to an outside of thedrainage drain pan 113. Accordingly, thegutter 103B itself is unable to be downsized to facilitate assembly. Therefore, according to theair conditioner 1 of this embodiment, the drainage port 3Ba of thegutter 3B is disposed anterior to the engaging portion of the downward protrusion 3Bc and theupward protrusion 13D in thedrainage drain pan 13. The downward protrusion 3Bc and theupward protrusion 13D are used to position themain body unit 3 and thedrainage drain pan 13. The downward protrusion 3Bc engaging thedrainage drain pan 13 can have a width W2 smaller than a width W1 of thegutter 3B because a leakage of water fed from the drainage port 3Ba of thegutter 3B to thedrainage drain pan 13 through the engaging portion to the outside of thedrainage drain pan 13 is prevented. Accordingly, since surplus widths W3 and W4 are provided on both sides of the downward protrusion 3Bc and these surplus widths W3 and W4 absorb the design errors, the facility of assembly between themain body unit 103 and thedrainage drain pan 113 is able to be improved. - Further, in the
air conditioner 1 of this embodiment, as illustrated inFIG. 2 andFIG. 3 , each of the downward protrusion 3Bc and theupward protrusion 13D is integrally formed of plural plate bodies intersecting one another. - The downward protrusion 3Bc includes a plate body 3Bc1 abutting the
upward protrusion 13D for engagement and a plate body 3Bc2 disposed to cross and to mate with the plate body 3Bc1. Thus, the plate body 3Bc2 becomes a reinforcing member when engaged with theupward protrusion 13D. Theupward protrusion 13D includes a plate body 13D1 abutting the downward protrusion 3Bc for engagement and a plate body 13D2 disposed to cross and to mate with the plate body 13D1. Thus, the plate body 13D2 becomes a reinforcing member when engaged with the downward protrusion 3Bc. Accordingly, according to thisair conditioner 1, the strength of the engagement between the downward protrusion 3Bc and theupward protrusion 13D is able to be improved. - Further, the
air conditioner 1 of this embodiment has the closed space 3Bb on the lower side of thegutter 3B. - According to this
air conditioner 1, without provision of a heat insulating material, insulation effectiveness is able to be obtained by the closed space 3Bb and the number of parts is able to be reduced. Conventionally, as illustrated inFIG. 5 , since thegutter 103B is put on theouter edge 113C of thedrainage drain pan 113, this closed space 3Bb is unable to be provided. - Further, in the
air conditioner 1 of this embodiment, thecontact plate 13E positioned below the drainage port 3Ba in thegutter 3B is provided on the bottom portion of thedrainage drain pan 13. - According to this
air conditioner 1, force of water going along thegutter 3B and fed to thedrainage drain pan 13 of theoutlet assembly 9 is able to be reduced by thecontact plate 13E. As a result, the water fed to thedrainage drain pan 13 is able to be prevented from being splashed. -
