The mechanism 11B is incorporated. A front panel 12 is mounted on the front surface of the suction grill 16 so as to be openable and closable with the upper portion serving as a fulcrum.

  In such an air conditioner 1, the main body 3 is formed with a gutter 3B on the right side where the drive motor 5 is provided in the present embodiment, as shown in FIG. The gutter 3 </ b> B is connected to the main body drain pan 3 </ b> A, is provided with the drain port 3Ba facing the drain drain pan 13 of the outlet assembly 9, and sends water accumulated in the main body drain pan 3 </ b> A to the drain drain pan 13.

  The gutter 3 </ b> B has a closed space 3 </ b> Bb formed under the gutter 3 </ b> B, which is enclosed by a plate material forming the main body 3. Further, the gutter 3B is formed with a downward projection 3Bc that projects rearward from the plate below the closed space 3Bb behind the drain port 3Ba. In addition, the gutter 3B has an abutment surface 3Bd facing the downward protrusion 3Bc side (front side) behind the downward protrusion 3Bc.

  As shown in FIGS. 2 and 3, the drainage drain pan 13 of the outlet assembly 9 is formed with a protruding portion 13B in which a lower portion of the gutter 3B protrudes rearward. The protruding portion 13B is formed with a protruding peripheral wall 13Ba surrounding the side portion and the rear portion thereof and connected to the peripheral wall 13C of the drainage drain pan 13. In this protruding portion 13B, an upward protrusion 13D protruding upward from a bottom portion connected to the drainage drain pan 13 is formed. In addition, the drainage drain pan 13 of the outlet assembly 9 has a bottom plate 13E formed with a contact plate 13E that stands upright at a position forward of the upward projection 13D.

  As shown in FIG. 2, when the main body 3 and the outlet assembly 9 are combined, the gutter 3 </ b> B and the drainage pan 13 abut against the rear surface of the protruding peripheral wall 13 </ b> Ba behind the protruding portion 13 </ b> B and face downward. The projection 3Bc contacts the front side of the upward projection 13D. Therefore, the gutter 3B and the drainage pan 13 are combined so as to sandwich the projecting peripheral wall 13Ba of the projecting portion 13B and the upward projection 13D between the contact surface 3Bd of the gutter 3B and the downward projection 3Bc. Since the drainage port 3Ba of the gutter 3B is located forward of the downward projection 3Bc, it is located forward of the upward projection 13D. Further, the contact plate 13E of the drainage drain pan 13 is disposed below the drainage port 3Ba of the gutter 3B.

  In such a configuration, the water in the main body drain pan 3A of the main body 3 is sent to the drainage drain pan 13 of the outlet assembly 9 along the gutter 3B, and from the drainage drain pan 13 to the outside of the air conditioner 1 through the drainage hose 13A. Is discharged.

  In the air conditioner 1 of the present embodiment, a main body 3 having a main body drain pan 3A provided corresponding to the heat exchanger 6 and a drain hose 13A arranged below the main body 3 and connected to the outside are connected. And a gutter 3B formed to be connected to the main body drain pan 3A and sending water from the main body drain pan 3A to the drainage drain pan 13. A downward projection 3Bc is provided below the gutter 3B, and a downward projection is provided. An upward projection 13D with which the 3Bc is engaged is provided on the inner bottom of the drain drain pan 13, and the drain port 3Ba of the gutter 3B is disposed inside the drain drain pan 13 than the downward projection 3Bc and the upward projection 13D.

  According to the air conditioner 1, positioning of the main body 3 and the drainage pan 13 can be achieved by engagement of the downward projections 3Bc and the upward projections 13D with the inner bottom of the drainage pan 13. By disposing the drain outlet 3Ba of the gutter 3B on the inner side of the drain drain pan 13 than the downward projection 3Bc and the upward projection 13D engaged at the inner bottom of the drain drain pan 13, drainage from the drain outlet 3Ba of the gutter 3B is performed. The water sent to the drain pan 13 is guided to the inside of the drain drain pan 13 from an engagement portion where the main body 3 and the drain drain pan 13 are positioned. For this reason, it is possible to prevent water sent from the drain port 3Ba of the gutter 3B to the drain drain pan 13 from leaking to the outside of the drain drain pan 13 through the engaging portion for positioning the main body 3 and the drain drain pan 13.

  As shown in FIG. 5, in the conventional air conditioner, the drain port 103Ba of the gutter 103B is bent downward, and the back side thereof is hung on the outer edge 113C of the drain drain pan 113, and the main body 103 is placed in the drain drain pan 113B. It has been assembled. Therefore, when water accumulates in the drain drain pan 113 and reaches the drain outlet 103Ba of the gutter 103B, the water rises due to a capillary phenomenon between the back side of the gutter 103B and the outer edge 116C of the drain drain pan 113, and leaks to the outside of the drain drain pan 113. There is a risk. According to the air conditioner 1 of the present embodiment, this problem can be solved.

  Moreover, according to the air conditioner 1 of the present embodiment, by disposing the drain outlet 3Ba of the gutter 3B inside the drain drain pan 13 than the downward projection 3Bc and the upward projection 13D, as shown in FIG. The downward projection 3Bc engaged with the drainage drain pan 13 can be formed to have a width W2 smaller than the width W1 of the gutter 3B. Conventionally, as shown in FIG. 5, since the gutter 103B is hung on the outer edge 113C of the drainage pan 113, the gutter 103B itself cannot be reduced in size. For this reason, according to the air conditioner 1 of the present embodiment, the extra widths W3 and W4 are provided on both sides of the downward projection 3Bc. The assembly accuracy with the drainage pan 113 can be improved.

  Further, in the air conditioner 1 of the present embodiment, as shown in FIGS. 2 and 3, the downward projections 3Bc and the upward projections 13D are formed integrally with a plurality of plate bodies crossing each other.

  According to the air conditioner 1, the engagement strength of the downward projection 3Bc and the upward projection 13D can be improved.

  Further, the air conditioner 1 of the present embodiment has a closed space 3Bb below the gutter 3B.

  According to this air conditioner 1, a heat insulating effect can be obtained without providing a heat insulating material by the closed space 3Bb, and the number of parts can be reduced. Conventionally, as shown in FIG. 5, since the gutter 103B is hung on the outer edge 113C of the drainage pan 113, such a closed space 3Bb is not provided.

  Further, in the air conditioner 1 of the present embodiment, a contact plate 13E located below the drain port 3Ba in the gutter 3B is provided at the bottom of the drain drain pan 13.

  According to this air conditioner 1, the force of water sent to the drainage pan 13 of the outlet assembly 9 along the gutter 3B can be suppressed by the plate 13E. As a result, it is possible to prevent the water sent to the drain drain pan 13 from scattering.
