Some existing air conditioner indoor units have multiple air outlets, and the multiple air outlets can have multiple air outlet forms, thereby meeting the various air supply needs of users. However, the airflow blown out by these air conditioner indoor units with multiple air outlets still has the problem of strong airflow when blowing toward the user, making the user uncomfortable. In view of the above problems, the present utility model is proposed to provide an air conditioner indoor unit that overcomes the above problems or at least partially solves the above problems, and can achieve a soft airflow blown out by the air conditioner indoor unit, which can bring a better air supply experience to the user.

FIG. 1 is a schematic front view of an indoor unit of an air conditioner according to an embodiment of the present invention. Referring to FIG. 2 to FIG. 7 , the present invention provides a microporous air outlet structure 18 for an indoor unit of an air conditioner, comprising an air outlet plate 181 and a plurality of convex strips 184 arranged on the rear surface of the air outlet plate 181. The plurality of convex strips 184 are arranged in parallel, so that a plurality of first grooves 183 are formed on the rear side of the air outlet plate 181. A plurality of second grooves 185 are arranged on the rear wall of each convex strip 184, and each second groove 185 penetrates the two side walls extending along the length direction of the corresponding convex strip 184, so that the groove wall of each second groove 185 includes two first walls 1851 spaced and opposite to each other along the length direction of the convex strip 184 and a second wall 1852 connecting the two first walls 1851. A plurality of micropores 182 are arranged on the air outlet plate 181, and some of the micropores 182 penetrate the air outlet plate 181 on the convex strip 184, and at least some or all of the micropores 182 penetrate the air outlet plate 181 on the groove wall. The airflow to be blown out of the indoor unit of the air conditioner first passes through the microporous air outlet structure 18 and is then broken up into a tiny airflow, and blown out from the micropores 182, so that the blown airflow becomes soft and does not cause discomfort when blowing toward the user, thereby improving the user experience. Furthermore, the second groove 185 runs through the side wall of the corresponding convex strip 184, so that at least part of the airflow blowing toward the first groove 183 and close to the corresponding second groove 185 can also enter the micropores 182 in the second groove 185, so that the air volume will not be reduced too much when the breeze outlet structure is set. At the same time, the airflow blowing toward the second groove 185 enters the micropores 182 under the guidance of the first wall 1851 or reaches the second wall 1852 under the guidance of the first wall 1851, and then enters the micropores 182, which also reduces wind resistance and reduces the disturbance of airflow.

Furthermore, in some embodiments of the present invention, as shown in FIG4 , the opening of the second groove 185 is larger than the bottom wall of the second groove 185 and the second groove is a tapered groove. This arrangement is more conducive to guiding the airflow into the second groove 185 .

Furthermore, in some embodiments of the present invention, each first wall 1851 is a curved surface or a slope.

In some other embodiments of the present invention, at least a portion of the micro holes 182 all penetrate the air outlet plate 181 on the second wall 1852 .

In other embodiments of the present invention, at least a portion of the micro holes 182 all penetrate the air outlet plate 181 on the first wall 1851 .

In some other embodiments of the present invention, at least part of the micro holes 182 are located on the first wall 1851 and the rest of the micro holes 182 are located on the second wall 1852 and penetrate the air outlet plate 181 .

In some other embodiments of the present invention, at least part of the micro holes 182 are on the first wall 1851 and the rest of the micro holes 182 are on the rear wall of the protruding strip 184 and penetrate the air outlet plate 181 .

In other embodiments of the present invention, at least part of the micro holes 182 are partially on the first wall 1851 , partially on the second wall 1852 , and the rest are on the rear wall of the protruding strip 184 and penetrate the air outlet plate 181 .

Of course, it can also be a combination of one or more of the above five distribution situations of micropores 182. For example, in some embodiments of the present utility model, as shown in FIG3, at least part of the micropores 182 all penetrate the air outlet plate 181 on the second wall 1852. At least part of the micropores 182 all penetrate the air outlet plate 181 on the first wall 1851 and at least part of the micropores 182 partially penetrate the air outlet plate 181 on the first wall 1851 and the rest penetrate the air outlet plate 181 on the second wall 1852 and at least part of the micropores 182 partially penetrate the air outlet plate 181 on the first wall 1851 and the rest penetrate the air outlet plate 181 on the rear wall of the convex strip 184 and at least part of the micropores 182 partially penetrate the air outlet plate 181 on the first wall 1851, partially penetrate the second wall 1852 and the rest penetrate the air outlet plate 181 on the rear wall of the convex strip 184. The above-mentioned arrangement of micropores 182 is conducive to reducing the wind resistance of airflow passing through the microporous air outlet structure 18, and at the same time is conducive to minimizing the loss of air volume.

In some embodiments of the present invention, at least part of the micropores 182 penetrate the air outlet plate 181 at the bottom wall of the first groove 183. In other words, at least part of the airflow toward the first groove 183 can be blown out from the micropores 182 that penetrate the air outlet plate 181 at the bottom wall of the first groove 183. This further reduces the influence of the micropore air outlet structure 18 on the air volume.

In some embodiments of the present invention, 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 contacts the airflow blowing from the rear earlier, and because the second groove runs through the corresponding convex strip, in addition to the airflow toward the second groove can enter the second groove, the airflow toward the first groove and passing through the second groove but not reaching the first groove can also partially enter the second groove, which is conducive to making more airflow blow out from the micropores 182 of the second groove 185.

In some embodiments of the present invention, the ratio of the depth of the second groove 185 to the thickness of the ridge 184 is 0.3 to 0.5. Preferably, the ratio of the depth of the second groove 185 to the thickness of the ridge 184 is 0.4.

In some embodiments of the utility model, as shown in FIG. 3 and FIG. 6 , a plurality of micropores 182 on the bottom wall of each first groove 183 are arranged in sequence at equal intervals along the length direction of the first groove 183. A plurality of micropores 182 on each convex strip 184 that penetrate the air outlet plate 181 are arranged in sequence at equal intervals along the length direction of the convex strip 184. The equal spacing makes the front side of the micropore air outlet structure 18 look regular. Further, in some embodiments, the spacing between adjacent micropores 182 arranged in sequence along the length direction of the first groove 183 is equal to the spacing between adjacent micropores 182 on each convex strip 184 that penetrate the air outlet plate 181.

In some embodiments of the present invention, as shown in FIG3 and FIG6, two columns or two rows of micropores 182 arranged on adjacent convex strips 184 and first grooves 183 are staggered. This arrangement is conducive to the airflow along the length direction of the convex strips 184 or the first grooves 183 to have corresponding micropores 182 for easy outflow of airflow, and makes the micropores 182 on the front side of the micropore air outlet structure 18 look staggered and aesthetically pleasing.

In some embodiments of the present invention, as shown in FIG6 , the apertures of all micropores 182 are equal. Of course, in other embodiments, the apertures of all micropores 182 may be equal or unequal, for example, the apertures of the micropores 182 on the convex strips 184 are larger, and the apertures of the micropores 182 on the first grooves 183 are smaller.

In some embodiments of the present invention, as shown in FIG5 , the opening of the first groove 183 is larger than the bottom wall of the first groove 183 . This arrangement is more conducive to guiding the airflow into the first groove 183 .

Furthermore, in some embodiments of the present invention, the first groove 183 is a tapered groove.

In some embodiments of the present invention, as shown in FIG5 , each micropore 182 has an inlet 1821 at the rear side and an outlet 1822 at the front side. The inlet 1821 is larger than the outlet 1822. In these embodiments, the airflow entering the micropore 182 flows out of the outlet of the micropore 182 at a speed greater than the speed entering from the inlet. This arrangement is conducive to the airflow flowing to a farther place, so that the airflow blown out by the air conditioner can take care of users at a farther distance.

Furthermore, in some embodiments of the present invention, as shown in FIG. 5 , the micropores 182 are tapered micropores.

In some embodiments of the present invention, as shown in Fig. 5, the ratio between the thickness of the air outlet plate 181 and the thickness of the convex strip 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.

In some embodiments of the present invention, the angle between the side wall of the convex strip 184 and the rear surface of the air outlet plate 181 is 75° to 90°. Preferably, the angle between the side wall of the convex strip 184 and the rear surface of the air outlet plate 181 is 85°.

In some embodiments of the present invention, the ratio between the width of the rear wall of the protruding strip 184 and the width of the bottom wall of the first groove 183 is 0.9 to 1.1.

In some embodiments of the present invention, the air outlet plate 181 includes a first air outlet plate edge 187 and a second air outlet plate edge 188 parallel to the convex strip 184 , the first air outlet plate edge 187 is provided with the convex strip 184 , and the second air outlet plate edge 188 is provided with a first groove 183 .

That is, a microporous air outlet structure 18 is provided at both second air outlets 17. The indoor unit of the air conditioner with two air outlet columns 10 can have a variety of air outlet modes. For example, one air outlet column 10 can be selected as needed to blow out airflow alone or two air outlet columns 10 can blow out airflow at the same time to increase the air volume. For another example, the first air outlet 11 and the second air outlet 17 are arranged at different angles, which can increase the air outlet angle of the indoor unit of the air conditioner. Obviously, when the two second air outlets 17 blow out airflow, the blown airflow becomes a tiny airflow, and when the second air outlet 17 is facing the user, the user will feel comfortable.

In some embodiments of the utility model, the front surface of each air outlet column 10 has a portion disposed between the corresponding first air outlet 11 and the corresponding second air outlet 17 as an air guide surface 30.

When at least one air guide plate 12 moves to the wide-angle air guide position, the edge of the air guide plate 12 closest to the air guide surface 30 close to the air guide surface 30 is located on the front side of the air guide surface 30. During operation, the air guide plate 12 rotates to guide the direction of the wind blown out from the first air outlet 11. In particular, when the air guide plate 12 is turned to the wide-angle air guide position, at least a portion of the airflow blown out from the first air outlet 11 enters the wide-angle air duct defined by the air guide surface 30 and the air guide plate 12, and is blown out in a direction away from the other air outlet column 10, thereby expanding the air outlet angle of the first air outlet 11, and then making the air outlet angles of the two air outlet columns 10 larger, thereby meeting the user's demand for wide-angle air supply of the air conditioner indoor unit.

When the two air outlet columns 10 discharge air forward, the air in the air induction interval 20 is driven forward by negative pressure, so that the air is mixed with the air blown out by the two air outlet columns 10, and during cooling, the air outlet temperature is increased, so that the wind is not too "hard", and the effect of "soft" wind is produced.

In some embodiments of the present invention, as shown in Fig. 1, two air outlet columns 10 are symmetrically arranged about a vertical reference plane extending forward and backward. The symmetrically arranged air outlet columns 10 make the indoor unit of the air conditioner look stable and in line with the aesthetic taste of Chinese people.
