Locking holes 46 into which the locking parts 45 are inserted are formed in the side edge support parts 34 of the grille 3 .

At the front end of the locking part 45, an engaging part 45a having a diameter slightly larger than the inner diameter of the locking hole 46 is provided. By pressing the locking part 45 into the locking hole 46, the engaging part 45a is positioned in the locking hole as shown in the figure. 46, so as to be in such an installed state, that is, as long as there is no external force, the upward movement of the front end of the top grid panel 7 is prevented, and the movement of the front and rear directions is also prevented.

In addition, as shown in FIG. 11A, on the rear frame 21d of the top grille panel 7, a rear protrusion 24 extending over its entire length is formed. The rear end of the top grille panel 7 is also prevented from moving upward when the vertical wall 3 b is mounted in the engaging recess 47 .

When detaching the top grille panel 7 in such a structure, firstly, the both ends in the width direction of the cross brace 22 on the side of the front frame 21C are pinched with fingertips and lifted up. In this way, when a force of lifting is applied to the front end of the top grille panel 7, as shown in FIG. through hole 46. Then, the locked state of the front end of the top grille panel 7 is released, and then, by pulling the top grille panel 7 obliquely upwards in front of the body, as shown in FIG. The locking state of the rear end is also released, and the top grille panel 7 can be detached from the front grille 3 . However, the top grille panel 7 can be installed on the front grille 3 through the above-mentioned reverse steps.

As explained above, the structure of each of the above-mentioned embodiments is that the top grille panel 7 and the front grille 3 that cover the upper suction port 6 formed on the front grille 3 of the main body casing 1 are provided separately, and , the top grille panel 7 can be detachably installed on the front grille 3, therefore, when the top grille panel 7 needs to be cleaned, it can be removed from the front grille 3, and can be It is possible to maintain a safe posture and to check the dirty part and degree while properly combining methods such as washing with water for cleaning. Therefore, the cleaning operation can be carried out in a shorter time and more conveniently.

In addition, especially in Embodiments 1 and 2, the top grille panel 7 is detached by sliding substantially along the front and rear directions of the indoor unit. Therefore, the indoor space required for the detachment work can be minimized as much as possible. workspace above the machine. Therefore, the indoor unit can be installed close to the indoor ceiling, ensuring the freedom of selection of the installation position.

In addition, as the top grille panel 7 in Embodiment 1, the outward widening portion 26 protruding from the left and right frames 21a, 21b is located below the top panel portion 31, and the rear protrusion 24 is fitted into the front grille 3. The installation state of the engaging hole 36 prevents upward loosening, and the handle 25 is located below the upper edge of the front panel 5.
