The second rib 21 is formed such that an angle between the lower end of the second rib 21 and the rear end of the front end portion 47 a of the bottom panel body 47 is 90 ° to 120 °. As shown in FIG. 4, in the second rib 21, a relief 80 is formed in order to avoid interference with the arm 52 of the flap 10.

Next, the attachment method of the bottom panel 16 of the indoor unit 1 of the air conditioner 100 of this embodiment is demonstrated.
The bottom panel 16 engages the first engaging portion 23 provided on the lower portion of the base 13 with the second engaging portion 32 provided on the upper surface of the bottom panel main body 47, and the width direction W of the base 13 And the fourth engaging portion 44 provided in the stay portion 48 of the bottom panel 16 are engaged with each other, and the bottom panel fastening structure 64 is used to It is attached by fastening 47 to the base 13.

The bottom panel body 47 is supported by the engagement of the first protrusion 26 of the first engagement portion 23 and the second protrusion 34 of the second engagement portion 32.
Both ends in the width direction W of the bottom panel body 47 are supported by the engagement of the third projecting portion 40 of the third engaging portion 38 and the fourth projecting portion 46 of the fourth engaging portion 44. By inserting the fourth engagement portion 44 from the lower side of the third engagement portion 38, the third engagement portion 38 and the fourth engagement portion 44 can be engaged.
At this time, the fourth introduction slope 62 of the fourth engagement portion 44 slides on the third introduction slope 42 of the third engagement portion 38, and the fourth base 45 of the fourth engagement portion 44 elastically deforms. The fourth base 45 is easily deformed inward in the width direction W because the fourth base 45 has a plate shape and the main surface of the fourth base 45 faces the width direction W.

The bottom panel body 47 can be fastened to the base 11 using the bottom panel fastening structure 64. Specifically, the bottom panel body 47 can be fixed to the base 13 by fastening the fastened plate portion 66 of the bottom panel body 47 to the screw hole plate portion 30 of the base 13 using a screw.
After the bottom panel body 47 is fixed, the opening 65 of the bottom panel body 47 can be closed using the cap 68.

Next, the action of the first rib 18 will be described.
By providing the curved portion 79 in the bottom panel main body 47 of the present embodiment, the indoor unit 1 can be designed so as not to give the user a feeling of oppression. By forming the first rib 18 in the curved portion 79, the strength of the curved portion 79 can be improved. In addition, when the indoor unit 1 tries to tilt to the front FB1 by its weight, the first rib 18 stretches against the wall surface Wa.

Next, the operation of the second rib 21 will be described.
During cooling, cold air is discharged from the air outlet 9. Under the present circumstances, when there is no 2nd rib 21, cold wind blows off from the crevice between flap 10 and bottom panel 16. This may cause condensation to occur. By providing the second rib 21 on the bottom panel 16 of the present embodiment, cold air blown out from the gap between the flap 10 and the bottom panel 16 is blocked.

According to the above embodiment, by providing the curved portion 79 in the bottom panel body 47, the indoor unit 1 can be designed so as not to give a feeling of oppression to the user. Further, by providing the first rib 18 on the bottom panel 16, when the indoor unit 1 tries to tilt to the front FB1 by its weight, the indoor unit 1 is forwardly pushed by the first rib 18 being stretched against the wall surface Wa. It is possible to prevent tilting to FB1.

In addition, when the bottom panel 16 is fastened to the base 11 by the baffle member 67 provided on the bottom panel 16, the cap 68 is used to cover the opening 65 using the cap 68. It can be prevented from getting inside.

In addition, condensation can be prevented because the second rib 21 shuts off cold air during cooling. That is, it is possible to prevent cooling air from blowing between the bottom panel 16 and the flap 10 and cooling the bottom panel 16 and the flap 10 during cooling.

Further, by the bottom panel 16 extending in the width direction W, thermal expansion occurs such that the width in the width direction W is increased. The first engaging portion 23 and the second engaging portion 32 are configured such that the first projecting portion 26 of the first engaging portion 23 and the second projecting portion 34 of the second engaging portion 32 project in the width direction W. When the bottom panel 16 is thermally expanded in the width direction W, the engagement margin is reduced and the engagement is easily released.

On the other hand, according to the configuration of the present invention, the bottom panel 16 is formed by the first projecting portion 26 of the first engaging portion 23 and the second projecting portion 34 of the second engaging portion 32 projecting in the front-rear direction FB. By thermally expanding in the width direction W, the engagement between the first engagement portion 23 and the second engagement portion 32 can be prevented from becoming insufficient. That is, even when the bottom panel 16 thermally expands in the width direction W, since the engagement margin in the front-rear direction FB is not affected, the disengagement can be prevented.

In addition, by providing the cross ribs 57 on the top surface of the bottom panel body 47, the bottom panel 16 can be made to have a strong structure. That is, even when the bottom panel 16 has a long shape in the width direction W, the strength can be improved without increasing the thickness of the bottom panel 16.

Further, by engaging the third engaging portions 38 provided at both ends in the width direction W of the base 13 and the fourth engaging portions 44 provided at both ends of the bottom surface panel 16, both end portions of the bottom surface panel 16 Can be prevented from falling downward.
