A plurality of second grooves 185 are disposed on the rear wall of each protrusion 184, and each second groove 185 penetrates through two side walls of the corresponding protrusion 184 extending along the length direction, so that the groove wall of each second groove 185 includes two first walls 1851 spaced along the length direction of the protrusion 184 and opposite to each other, and a second wall 1852 connecting the two first walls 1851. The air outlet plate 181 is provided with a plurality of micro holes 182, part of the micro holes 182 penetrate through the air outlet plate 181 on the raised strips 184, and at least part or all of the micro holes 182 penetrate through the air outlet plate 181 on the groove wall. The air flow to be blown out of the indoor unit of the air conditioner is firstly scattered through the micropore air outlet structure 18 and then changed into micro air flow, and the micro air flow is blown out of the micropores 182, so that the blown air flow becomes soft, uncomfortable feeling is not generated when the air flow is blown to a user, and the user experience is improved. Further, the second grooves 185 penetrate through the side walls of the corresponding protruding strips 184, so that at least part of the air flow which is blown to the first grooves 183 and is close to the corresponding second grooves 185 can enter the micro holes 182 in the second grooves 185, and therefore excessive air quantity is not reduced when a breeze air outlet structure is arranged, and meanwhile, the air flow blown to the second grooves 185 enters the micro holes 182 under the guidance of the first walls 1851 or enters the second walls 1852 under the guidance of the first walls 1851, and then enters the micro holes 182, so that wind resistance is reduced, and disturbance of the air flow is reduced.

Further, in some embodiments of the present utility model, as shown in fig. 4, the second groove 185 is open larger than the bottom wall of the second groove 185 and the second groove is tapered. This arrangement is more advantageous in directing the airflow into the second recess 185.

Thereby further reducing the effect of the microporous air-out structure 18 on the air volume.

In some embodiments of the utility model, the depth of the second groove 185 is less than the depth of the first groove 183. That is, the second wall 1852 of the second groove 185 is located at the rear side of the bottom wall of the first groove 183, so that the second groove 185 is brought into contact with the air flow blown from the rear earlier, and since the second groove penetrates the corresponding convex strip, in addition to the air flow toward the second groove, the air flow toward the first groove and passing through the second groove, which has not yet reached the first groove, can also partially enter the second groove, so that it is advantageous to blow out more air flow from the micro holes 182 of the second groove 185.

In some embodiments of the present utility model, as shown in fig. 3 and 6, two rows or columns of micro-holes 182 are provided on adjacent ribs 184 and first grooves 183 in a staggered manner. This arrangement facilitates the flow of air along the length of either the ribs 184 or the first grooves 183 with corresponding micro-holes 182 to facilitate the flow of air out, and also makes the micro-holes 182 on the front side of the micro-hole air-out structure 18 appear to be aesthetically pleasing.

In some embodiments of the present utility model, as shown in FIG. 6, the pore sizes of all of the microwells 182 are equal. Of course, in other embodiments, the pore sizes of all the pores 182 may be equal or unequal, for example, the pore sizes of the pores 182 on the ribs 184 are larger, and the pore sizes of the pores 182 on the first grooves 183 are smaller.

In some embodiments of the utility model, as shown in fig. 5, the opening of the first recess 183 is larger than the bottom wall of the first recess 183. This arrangement further facilitates directing the airflow into the first recess 183.

In these embodiments, the airflow entering the micro-holes 182 flows out from the outlets of the micro-holes 182 at a greater rate than from the inlets, which facilitates the airflow to flow farther away, allowing the airflow from the air conditioner to be used for longer distance users.

Further, in some embodiments of the present utility model, as shown in fig. 5, the microwells 182 are tapered microwells.

In some embodiments of the utility model, as shown in FIG. 5, the ratio between the thickness of the air plate 181 and the thickness of the ribs 184 is 0.8 to 1.2. Preferably, the ratio between the thickness of the air outlet plate 181 and the thickness of the convex strip 184 is 1.
