air conditioner which has a simple structure, improves the
performance of the air conditioner and increases the energy
efficiency ratio.
[0005] In order to achieve the above purpose, the application
provides the fallowing technical solutions.
[0006] An indoor unit of air conditioner comprising: a panel body
enclosing side portions and a top portion of the air conditioner
for installing a front panel, a rear shell enclosing a rear portion
of the air conditioner, and the front panel arranged in the front
of the air conditioner and closely connected to the panel body; the
rear shell, the panel body and the front panel form an inner
chamber of the air conditioner in which a heat exchanger, a control
element, and a ventilating component are provided; an air outlet is
provided at a lower portion of the front panel, an air deflector is
mounted on the front panel or is arranged on the panel body for
opening or closing the air outlet; wherein a vortex forming device
is provided at a bottom surface of the air outlet.
[0007] The vortex forming device is configured as a serrated
surface with a plurality of concave grooves.
[0008] To sum up, the application has the following advantageous
effects:
[0009] In the indoor unit of air conditioner according to the
application, since the vortex forming device is provided at the
bottom surface of the air outlet and the vortex forming device is
configured as a serrated surface with a plurality of concave
grooves, air flow passing through the heat exchanger can form a
vortex flow at the serrated surface, which can ensure a relatively
even temperature at the air outlet, and avoid forming condensate
water due to a partially large temperature difference. Thus the
condensation could be improved.

shown in FIGS. 3 and 6, the panel body 2 comprises a rear frame 29
at a rear portion, a left side plate 28 and a right side plate 28.
At least one side of the rear frame 29 protrudes outside the side
plate 28 and forms 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 decorative edge of side portion of the
indoor unit of air conditioner.
[0031] Preferably, each of a left side and a right side of the
joint 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, and
each of a left side and a right side of the indoor unit has a
decorative edge.
[0032] Top portions of the front panel 1 and the rear frame 29 are
higher than a top surface of the rear shell.

width L2 of the panel body skirt structure 20 are between 2 and 8
mm, and preferably are 4 mm. The height H1 of the front panel skirt
structure 10 and the height H2 of the panel body skirt structure 20
are between 3 and 10 mm, and preferably are 8 mm.
[0034] As shown in FIG. 6, an opening 291 for installing the rear
shell is provided at a back portion of the panel body 2, and a rear
boss 27 is provided at a lower edge of the opening 291. After the
air conditioner is mounted, the rear boss 27 withstands a wall to
form an installing space for a drain pipe and a refrigerant
connecting pipe between the rear shell and the wall.
[0035] The rear boss 27 is arranged in a transverse direction, and
has upward bending portions at left and right ends thereof.
[0036] The size of the rear boss 27 in a horizontal direction is
less than that of the rear frame 29.
