DETAILED DESCRIPTION

[0018] The present invention provides an indoor unit of an air conditioner. As is shown in FIGS. 1 to 6, the indoor unit of the air conditioner comprises: a panel body 2 encasing side portions and a top portion of the air conditioner and configured to mount a front panel; a rear housing 1 encasing a rear portion of the air conditioner; and the front panel 3 located in front of the panel body and closely connected to the panel body. The rear housing 1, the panel body 2 and the front panel 3 define an inner cavity of the air conditioner, and a heat exchanger, a control element and a ventilation component are provided in the inner cavity. An air outlet 4 is provided at a lower portion of the front panel 3. An air deflector 5 is mounted on the front panel 3 or is provided on the panel body 2, and is configured to open and close the air outlet 4.

[0019] An eddy formation device 6 is provided at a bottom portion of the air outlet 4, and is fixed on the front panel 3 or the panel body 2 in a horizontal direction and is of an elongated strip-like structure. The eddy formation device 6 comprises at least one concave groove 7 extending in a horizontal direction. A concave direction of the concave groove 7 intersects an air outlet direction of the air conditioner at an angle.

[0020] Preferably, the eddy formation device 6 is formed by closely attaching an elongated strip-like member to a bottom surface of the air outlet 4 in the horizontal direction.

[0021] Preferably, the eddy formation device 6 is formed by closely attaching two or more elongated strip-like members to the bottom surface of the air outlet 4 in the horizontal direction in sequence.

[0022] The eddy formation device 6 has a horizontal width smaller than or equal to a width of the air outlet 4.

[0023] As shown in FIG. 7, an air baffle rib 8 is provided at the top portion of the air outlet 4.

[0024] The air baffle rib 8 extends from the top portion of the air outlet 4 towards the air outlet 4.

[0025] The air baffle rib 8 is an elongated rib-like member attached closely to the top portion of the air outlet 4 in the horizontal direction, and has a horizontal width smaller than or equal to the width of the air outlet 4.

[0026] When an air flow is passing through the air baffle rib 8 after having passed through the heat exchanger, a pressure of the air flow is changed under the action of the air baffle rib 8, a moving direction of the air flow is impeded to be changed, which can ensure a relatively uniform temperature at the air outlet and avoid a partial excessive temperature difference to generate condensate water, thereby reducing the occurrence of condensation.

[0027] As shown in FIG. 8, the panel body 2 is provided with a notch for mounting the front panel 3 and a rabbet for fixing the rear housing I. The panel body 2 extends towards the top of the air outlet 4 to form the air baffle rib 8. A water film region 9 is formed between a bottom portion of the front panel 3 and the air baffle rib 8.

[0028] As shown in FIG. 9, the rear housing 1 extends towards the top of the air outlet 4 to form the air baffle rib 8, and the rear housing 1 encases the panel body 2 such that the panel body 2 is located behind the air outlet 4.

[0029] As shown in FIG. 10, the air baffle rib 8 is adhered to the front panel 3; or the front panel 3 extends towards the top of the air outlet 4 to form the air baffle rib 8.

[0030] The above embodiments are not used to limit the invention. Various improvements and modifications made by those skilled in the art without departing from the scope of the present invention should be deemed to fall into the protection scope of the present invention.
