9. The inside unit of the air conditioner of claim 8 , wherein the access hole is located on a longitudinally extending line of the mounting bracket.
10. The inside unit of the air conditioner of claim 8 , wherein the grille accommodating portion includes an edge portion that extends toward the mounting bracket along the perimeter of the access hole.
11. The inside unit of the air conditioner of claim 1 , further comprising:
a drain pan assembly provided at an inner side of the cabinet, the drain pan assembly forming an air flow passage and collecting condensed water generated at the heat exchanger; and
an orifice member provided at the drain pan assembly, the orifice member forming a passage for the suctioned air to flow toward the fan.
12. The inside unit of the air conditioner of claim 1 , further comprising:
a drain pan assembly provided at an inner side of the cabinet, the drain pan assembly forming an air flow passage and collecting condensed water generated at the heat exchanger;
a panel opening provided at a center of the front panel;
a suction grille configured to open and close the panel opening and forming the inlet port; and
a control box provided at the inner side of the cabinet and exposed to the panel opening.
13. The inside unit of the air conditioner of claim 12 , further comprising:
a control box accommodating portion to accommodate the control box, the control box accommodating portion being formed in the drain pan assembly proximate a side surface of the cabinet.
14. The inside unit of the air conditioner of claim 12 , wherein a length of the control box is shorter than a width of the panel opening such that the control box is exposed through the panel opening.
15. The inside unit of the air conditioner of claim 12 , wherein the control box comprises:
a box case to accommodate a printed circuit board, and
a box cover rotatably mounted on the box case and configured to be opened through the panel opening.
