[0049] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0050] Reference below Figure 1-Figure 22 An air-conditioning indoor unit 100 according to an embodiment of the first aspect of the present invention is described.

[0051] like Figure 1-Figure 2 As shown, according to an embodiment of the utility model, the air-conditioning indoor unit 100 includes: a shell 10, a shutter assembly 20 and an air outlet grille 30, and an air outlet is formed on the shell 10; the shutter assembly 20 is arranged in the shell 10 and close to the air outlet position, the shutter assembly 20 includes a plurality of shutters 21 arranged at intervals up and down, and the plurality of shutters 21 can swing up and down; the air outlet grille 30 is arranged at the air outlet position and is located downstream of the shutter assembly 20 in the air outlet direction, the air outlet grille 30 has a plurality of transverse ribs 31, the plurality of transverse ribs 31 extend in the horizontal direction and are arranged at intervals up and down, and in the air outlet direction, at least part of the transverse ribs 31 are inclined upward and / or downward relative to the horizontal direction.

[0052] Specifically, the housing 10 is mainly used to provide installation space for the shutter assembly 20 and the air outlet grille 30 .

[0053] The shutter assembly 20 mainly adjusts the air supply direction of the air outlet by swinging the shutter 21 in the up and down direction, so that the user can adjust the air supply direction according to seasonal changes or personal preferences. For example, in summer, the shutter 21 can be adjusted to supply air upward to promote cold air circulation, and in winter, the shutter 21 can be adjusted to supply air downward to quickly increase the room temperature, thereby improving the comfort of air conditioning and customer experience. It should be noted that the number of shutters 21 can be designed according to actual conditions, for example, the number of shutters 21 can be two, three or more.

[0054] The air outlet grille 30 is arranged downstream of the louver assembly 20 in the air outlet direction, that is, the air outlet grille 30 is arranged on the front side of the louver assembly 20, that is, on the side of the air-conditioning indoor unit 100 facing the user, wherein the air outlet grille 30 is formed by a plurality of transverse rods and a plurality of longitudinal rods arranged in a cross-spaced manner, similar to a component with a mesh structure, and the air outlet grille 30 can be used to prevent accidents caused by users or animals accidentally touching the fan blades of the air-conditioning indoor unit 100, thereby improving the safety of use of the air-conditioning indoor unit 100.

[0055] Among them, "at least part of the transverse ribs 31 are inclined upward and / or downward relative to the horizontal direction" can be understood as that the air outlet grille 30 may have only transverse ribs 31 inclined upward relative to the horizontal direction, or only transverse ribs 31 inclined downward relative to the horizontal direction, or both transverse ribs 31 inclined upward relative to the horizontal direction and transverse ribs 31 inclined downward relative to the horizontal direction, wherein "at least part" is intended to explain that among all the transverse ribs 31 of the air outlet grille 30, only part may be inclined, or all may be inclined.

[0056] It should be noted that, in the above embodiment, the inclination direction of at least part of the transverse ribs 31 is consistent with the wind guide direction of the louver 21, thereby effectively reducing the obstruction of the airflow when passing through the air outlet grille 30, ensuring that the airflow flows smoothly and unimpeded in the predetermined direction, so that more airflow can enter the room through the air outlet grille 30, thereby improving the air conditioning transmission efficiency and the cooling / heating effect of the room.

[0057] According to the air-conditioning indoor unit 100 of the embodiment of the utility model, by setting at least part of the transverse ribs 31 to be inclined upward and / or downward relative to the horizontal direction, the inclination direction of at least part of the transverse ribs 31 can be made consistent with the wind guide direction of the louver 21, thereby reducing the resistance of the air flow through the air outlet grille 30, and increasing the air outlet volume of the air-conditioning indoor unit 100, thereby improving the working efficiency and cooling / heating effect of the air conditioner and improving the customer experience.

[0058] According to some embodiments of the utility model, the angle between at least part of the transverse ribs 31 and the horizontal plane is the same as the maximum swing angle between the louver 21 and the horizontal plane. In this way, it can be ensured that the airflow can continue to diffuse evenly along the direction set by the louver 21 after passing through the louver 21, thereby further reducing the resistance of the transverse ribs 31 to the airflow, thereby increasing the air volume of the air conditioner indoor unit 100 and improving the heat exchange effect of the air conditioner.

[0059] “The angle between at least some of the transverse ribs 31 and the horizontal plane is the same as the maximum swing angle between the louver 21 and the horizontal plane” It can be understood that the angle between some of the transverse ribs 31 and the horizontal plane can be the same as the maximum swing angle between the louver 21 and the horizontal plane, or the angle between all of the transverse ribs 31 and the horizontal plane can be the same as the maximum swing angle between the louver 21 and the horizontal plane.

[0060] According to some embodiments of the present invention, Figure 6As shown, in the direction from one end of the transverse rib 31 to the other end, the transverse rib 31 extends along a forward convex arc. The arc surface guides the airflow better, so that the airflow is better concentrated at the air outlet of the air outlet grille 30, thereby increasing the air volume at the air outlet and improving the output energy of the air conditioner indoor unit 100.

[0061] According to some embodiments of the utility model, the inclination direction of the plurality of transverse ribs 31 is the same. That is, the plurality of transverse ribs 31 may all be inclined upward or all be inclined downward. When the plurality of transverse ribs 31 are all inclined upward, it is beneficial to improve the cooling effect of the air conditioner in the cooling condition, and when the plurality of transverse ribs 31 are all inclined downward, it is beneficial to improve the heating effect of the air conditioner in the heating condition.

[0062] It should be noted that when the air conditioner is in cooling mode, since the cold air is relatively heavy, in order to cool the room better and faster, when the user uses the cooling effect, the louver 21 will tilt upward so that the cold air can blow to a higher position. Therefore, when the multiple transverse ribs 31 are all tilted upward, the multiple transverse ribs 31 can be parallel to the airflow direction of the cold air, thereby increasing the air volume of the cold air, thereby improving the cooling effect of the air conditioner.

[0063] When the air conditioner is in heating mode, since the density of the warm air blown out by the air conditioner is smaller than that of the cold air in the room, in order to warm up the room better and faster, when the user uses the heating effect, the louver 21 will tilt downward so that the warm air can blow to a lower position. Therefore, when the multiple transverse ribs 31 are all tilted downward, the multiple transverse ribs 31 can be parallel to the airflow direction of the warm air, thereby increasing the air volume of the warm air and thus improving the heating effect of the air conditioner.

[0064] According to some embodiments of the present invention, Figure 8 and Fig.16 As shown, the plurality of transverse ribs 31 include at least one first rib 311 and at least one second rib 312. In the air outlet direction, the first rib 311 is inclined upward, and the second rib 312 is inclined downward. It can be understood that the plurality of transverse ribs 31 have both upwardly inclined parts and downwardly inclined parts, so that the air conditioner can more flexibly adapt to the needs of different seasons or user preferences for different air supply modes. For example, in winter, the downwardly inclined ribs can be used more to enhance the ground heating effect, and in summer, the upwardly inclined ribs can be used to promote the sinking of cold air to achieve a better cooling effect.

[0065] It should be noted that the number of the first ribs 311 can be one or more, for example, one, two, three or more, and the number of the second ribs 312 can be one or more, for example, one, two, three or more.

[0066] According to some embodiments of the present invention, Figure 8 and Fig.16 As shown, in the up-down direction, the first rib 311 is arranged at the upper part of the air outlet, and the second rib 312 is arranged at the lower part of the air outlet. It should be noted that in the cooling condition, the louver 21 is tilted upward, and in the heating condition, the louver 21 is tilted downward. Therefore, in the up-down direction, the first rib 311 is arranged at the upper part of the air outlet, which reduces the resistance of the upper grille to the cold air, so that more cold air is directed to the top of the room, and then more cold air is settled from the top of the room, thereby further improving the cooling effect of the air conditioner and improving the user's comfort; the second rib 312 is arranged at the lower part of the air outlet, which reduces the resistance of the lower grille to the warm air, and can guide more warm air to the ground, thereby improving the heating effect of the air conditioner, making the room temperature more uniform, and thus improving the user's comfort.

[0067] According to some embodiments of the present invention, Figure 8 and Fig.16 As shown, the plurality of transverse ribs 31 further include at least one third rib 313, and the third rib 313 is horizontally arranged along the air outlet direction, and the third rib 313 is arranged between the first rib 311 and the second rib 312. It can be understood that the air outlet grille 30 has transverse ribs 31 arranged upwardly inclined, transverse ribs 31 arranged downwardly inclined, and transverse ribs 31 arranged horizontally, so that the airflow guidance and diffusion effect can be further fine-tuned to meet the needs of different room sizes, layouts or user preferences, thereby improving the adaptability and user satisfaction of the air conditioning system.

[0068] It should be noted that the number of the third ribs 313 may be one or more. For example, the number of the third ribs 313 may be one, two, three or more.

[0069] According to some embodiments of the present invention, Figure 3-Figure 14 As shown, the air outlet grille 30 also has a plurality of vertical ribs 32, which extend vertically and are arranged at intervals in the left-right direction, and each vertical rib 32 is connected to a plurality of transverse ribs 31. For example, the number of vertical ribs 32 can be two, three or more. Among them, the vertical ribs 32 are mainly used to fix and strengthen the structural strength of the transverse ribs 31, thereby increasing the structural strength of the entire air outlet grille 30, thereby improving the service life and reliability of the air outlet grille 30; at the same time, it can also prevent the transverse ribs 31 from being deformed, thereby ensuring the air outlet effect of the air outlet grille 30.

[0070] According to some embodiments of the present invention, Figure 6 and Fig.14As shown, there are two air outlets, which are arranged at intervals on the left and right. The number of shutter components 20 and the number of air outlet grilles 30 are both two, and they correspond to the two air outlets one by one. Compared with a single air outlet, two air outlets can more effectively cover a larger space area, thereby reducing airflow blind spots. Especially in a rectangular or open space, two air outlets can ensure that every corner can quickly reach an ideal temperature state.

[0071] It should be noted that the structure of two air outlets equipped with two air outlet grilles 30 and a shutter assembly 20 allows the air conditioning system to independently control the airflow on the left and right sides of the room. As a result, the user can adjust the air supply volume and direction of each air outlet according to the room layout or the usage requirements of different areas, thereby achieving more refined temperature regulation and improving overall comfort.

[0072] According to some embodiments of the present invention, Figure 6 and Fig.14 As shown, the width of the vertical ribs 32 on the opposite sides of the two air outlet grilles 30 is greater than the width of the other vertical ribs 32. That is to say, in this embodiment, vertical ribs 32 with larger widths are arranged at the edge positions on the opposite sides of the two air outlet grilles 30, wherein the vertical ribs 32 can generate resistance to the lateral diffusion of the airflow, thereby, the vertical ribs 32 with larger widths arranged at the edge positions can improve the diffusion of the edge airflow, and further improve the airflow velocity at the edge position of the air outlet, and can transport the airflow to a farther position, thereby increasing the heat exchange area and improving the uniformity of the indoor temperature.

[0073] According to some embodiments of the utility model, the air outlet grille 30 is rotatable around the vertically extending axis, and the air outlet grille 30 extends along an arc with the axis as the center. On the one hand, it is convenient to clean and repair the shutter assembly 20 and the components inside the air inlet. At the same time, since the air outlet grille 30 also has a certain wind guiding effect, on the other hand, the air outlet grille 30 is rotatable around the vertically extending axis, and the user can flexibly adjust the air outlet direction according to actual needs, thereby realizing a wider range of angle changes, so that the air conditioner indoor unit 100 can be applied to a variety of indoor layouts and usage scenarios.

[0074] According to some embodiments of the utility model, the air conditioner indoor unit 100 further includes: a motor 40, a mounting plate 33 extending toward the inside of the housing 10 is provided on the air outlet grille 30, and the motor 40 is connected to the mounting plate 33 to drive the air outlet grille 30 to rotate. It can be understood that the air outlet grille 30 is driven by the motor 40 to realize automatic rotation without manual adjustment, thereby improving the convenience and intelligence level of the air conditioner.

[0075] The air conditioner according to the embodiment of the second aspect of the utility model includes the air conditioner indoor unit 100 according to the embodiment of the first aspect of the utility model.

[0076] Furthermore, for example Fig.19 As shown, the housing 10 includes a rear frame 11, an air outlet frame 12, a display panel 13, a lower panel 14, a top cover 15 and a bottom plate 16. Specifically, the air outlet frame 12 has an air outlet, and the air outlet frame 12 is connected to the rear frame 11. The display panel 13 is arranged at the front end of the air outlet and is mainly used to open and close the air outlet; the lower panel 14 is arranged below the display panel 13 and is connected to the rear frame 11, and mainly plays a decorative role, which can increase the appearance of the air conditioner indoor unit 100.

[0077] According to the air conditioner of the embodiment of the utility model, the air conditioner indoor unit 100 of the first embodiment is provided, thereby improving the overall performance of the air conditioner.
