As shown in Figs. 1, 2, 5 and 6, the indoor unit of the air conditioner includes: a panel body 2 enclosing side portions and a top portion of the air conditioner and being configured for installing a front panel, a rear shell enclosing a rear portion of the air conditioner, and the front panel 1 arranged in the front of the air conditioner and closely connected to the panel body. The rear shell, the panel body 2 and the front panel 1 define an inner chamber of the air conditioner in which a heat exchanger 5, a control element, and a ventilating component 4 are provided. A lower portion of the front panel 1 is provided with an air outlet. An air deflector is mounted on the front panel 1 or is arranged on the panel body 2 for opening or closing the air outlet. A vortex forming device is provided at a bottom surface of the air outlet.

[0012] The vortex forming device is configured as a serrated surface 25 with a plurality of concave grooves. Air flow passing through the heat exchanger 5 can formed a vortex flow at the serrated surface 25, which can ensure a relatively uniform temperature at the air outlet, thereby can avoid the formation of condensate water due to a partially large temperature difference, and thus can reduce occurrence of dew-congealing phenomenon.

[0013] As shown in Figs. 1, 2, 5, 7 and 8, air-damping ribs 26 are provided on the panel body 1 in a region between the front panel and the heat exchanger.

[0014] The air-damping ribs 26 include more than one horizontal air-damping rib.

[0015] The air-damping ribs 26 further include more than one connecting strip distributed at intervals in a direction perpendicular to the horizontal air-damping ribs.

[0016] The heat exchanger 5 includes fins 52 and a plurality of copper pipes 51 penetrating through the fins 52. The horizontal air-damping ribs are arranged in front of a gap between two adjacent copper pipes 51, which are close to an air outlet region of the ventilating component 4, of the heat exchanger 5.

[0017] The rear shell is mounted at a rear portion of the panel body 2. A lower portion of a front portion of the panel body 2 is closely connected to a bottom portion of the front panel 1. Side surfaces of the indoor unit of the air conditioner are of a "U" shape structure. Front, rear and bottom surfaces of a lower portion of the indoor unit of the air conditioner are formed by more than one curved surface.

[0018] The front panel 1 includes, from the top to the bottom in sequence, a first combining surface 11, a second combining surface 12 and a third combining surface 13. A sectional profile line of the first combining surface 11 is of a straight line or an arc line with a curvature approaching to zero. A sectional profile line of the second combining surface 12 is of a curved line with a curvature gradually increased from upper to lower, and the maximum curvature is less than or equal to 0.025. A sectional profile line of the third combining surface 13 is of a curved line with a curvature gradually decreased from upper to lower, and the minimum curvature is larger than 0.0005.

[0019] An assembly of the panel body 2 and the rear shell includes, from front to rear in sequence, a fourth combining surface 21, a fifth combining surface 22, a sixth combining surface 23 and a seventh combining surface 24.

[0020] Sectional profile lines of the fourth combining surface 21, the fifth combining surface 22, the sixth combining surface 23 and the seventh combining surface 24 have different curvatures, respectively, such that a bottom of the air conditioner has an arc transition structure.

[0021] As shown in Figs. 3, 4 and 9, the front panel 1 covers the front portion of the panel body 2, and a width of the front panel 1 is larger than a width of the front portion of the panel body 2, thereby forming a front panel skirt structure 10 at at least one side of bonding portion of the front panel 1 and the panel body 2. As shown in Figs. 3 and 6, the panel body 2 includes: a rear frame 29 at a rear portion of the panel body 2, and a left side plate 28 and a right side plate 28. At least one side of the rear frame 29 extends beyond corresponding side plate 28 at the same side, thereby forming a panel body skirt structure 20. The front panel skirt structure 10 and the panel body skirt structure 20 are connected to form a "U" shape side decorative edge of the indoor unit of the air conditioner.

[0022] Preferably, each of a left side and a right side of the bonding portion of the front panel 1 and the panel body 2 is formed with the skirt structure 10, and each of a left side and a right side of the panel body 2 is formed with the panel body skirt structure 20, such that each of a left side and a right side of the indoor unit has a decorative edge.

[0023] Top portions of the front panel 1 and the rear frame 29 are higher than a top surface of the rear shell.

[0024] Widths L2 of the front panel skirt structure 10 and the panel body skirt structure 20 are ranged from 2 millimeter (mm) to 8mm, and preferably are 4mm. A height H1 of the front panel skirt structure 10 and a height H2 of the panel body skirt structure 20 are ranged from 3mm to 10mm, and preferably are 8mm.

[0025] As shown in Fig. 6, a back portion of the panel body 2 is formed with an opening 291 for installing the rear shell, and is provided with a rear boss 27 at a lower edge of the opening 291. After the air conditioner is mounted, the rear boss 27 abuts against a wall surface, to form an installing space for a drain pipe and a refrigerant connecting pipe between the rear shell and the wall surface.

[0026] The rear boss 27 is arranged in a transverse direction, and has upward bending portions at left and right ends thereof.

[0027] A size of the rear boss 27 in a horizontal direction is less than that of the rear frame 29.

[0028] The above embodiments are not intended to limit the present application. Various improvements and variations made by the person skilled in the art, without departing from the scope of the present application, are deemed to fall into the protection scope of the present invention as defined by the appended claims.
