In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] like Figures 1 to 10 As shown, the present application discloses a panel air outlet structure, including a panel frame 1, a return air outlet 2 is arranged at the center of the panel frame 1, and four air outlet assemblies 4 are arranged in four azimuth directions of the return air outlet 2, the air outlet assembly 4 includes at least one first air outlet 5, a first guide boss 6 is arranged in the first air outlet 5, the first guide boss 6 is arranged on the second air outlet side wall 502 of the first air outlet 5 close to the return air outlet 2, a first guide groove 7 and a second guide groove 8 are respectively formed on opposite sides of the first guide boss 6, the longest side of the first guide groove 7 is L1, the longest side of the second guide groove 8 is L2, the longest side of the first guide boss 6 is L3, and L3 is less than L1+L2.

[0038] The panel air outlet structure described in the present application improves the air outlet structure. Among the four air outlet assemblies 4, at least one air outlet is selected as the first air outlet 5. The first air outlet 5 is arranged in a long strip shape as a whole away from the air outlet surface of the indoor unit body 200. The first air outlet 5 is limited by the first air outlet side wall 501, the second air outlet side wall 502, the first end plate 13, and the second end plate 14. The first end plate 13 and the second end plate 14 are arranged at both ends of the length direction of the first air outlet 5. The second air outlet side wall 502 is a limiting wall on the first air outlet 5 close to the return air outlet 2. By setting a first guide boss 6 on the second air outlet side wall 502 to guide the air outlet, it is helpful to guide the air outlet to a specific direction and reduce the instability of the wind flow. The first guide groove 7 and the second guide groove 8 formed on both sides of the first guide boss 6 allow the wind flow to flow more orderly when passing through the panel, reducing the mutual collision between different wind flows, thereby reducing the noise level. At the same time, the first guide groove 7 and the second guide groove 8 are set as two structures of unequal lengths to achieve better control of the wind flow direction, reduce the intersection of cold and hot air at the air outlet, and thus reduce the possibility of condensation.

[0039] The panel air outlet structure described in the present application guides the airflow at the air outlet, reduces the wind speed, reduces airflow collision, reduces noise level, and reduces the occurrence of condensation, thereby improving the user experience by improving the panel air outlet structure.

[0040] As a preferred example of the present application, the second guide groove 8 is located at the front side of the first guide groove 7, and 2 / 3L2<L1<L2. This setting makes the guide groove length at the front end of the circumferential air outlet of the first air outlet 5 slightly larger than the guide groove length at the rear end of the air outlet. The normal air outlet direction in the first air outlet 5 refers to the air outlet airflow direction parallel to the axis of the fan blade assembly formed by the fan blade assembly of the indoor unit body 200, that is, the air outlet direction from the side close to the indoor unit body 200 to the side away from the indoor unit body 200 in the first air outlet 5. The circumferential air outlet direction in the first air outlet 5 refers to the air outlet airflow direction along the length direction in the first air outlet 5 formed by the fan blade assembly of the indoor unit body 200. The second guide groove 8 is located at the front side of the air outlet of the first guide groove 7, which means that the wind flow in the first air outlet 5 is guided from the second guide groove 8 to the wind outlet direction on one side of the first guide groove 7. This setting can more effectively guide the wind flow, produce a suitable speed difference, and facilitate the control of the distribution and speed of the wind flow.

[0041] As a preferred example of the present application, the first guide groove 7 is arranged with a cross-section gradually increasing from the side close to the indoor unit body 200 to the side away from the indoor unit body 200, and the second guide groove 8 is arranged with a cross-section gradually increasing from the side close to the indoor unit body 200 to the side away from the indoor unit body 200. That is, along the normal air outlet direction, the cross-sections of the first guide groove 7 and the second guide groove 8 gradually increase. This arrangement allows the wind flow to smoothly transition when passing through these guide grooves, reduces the sudden change of wind speed, improves the air outlet efficiency, reduces the occurrence of turbulence and eddy currents, helps to reduce the turbulence and instability of the wind flow, and also helps to reduce the friction and resistance between the wind flow and the surrounding structure, thereby reducing the generation of noise.

[0042] As a preferred example of the present application, the shortest side of the first guide groove 7 is L4, and the shortest side of the second guide groove 8 is L5, and L5>L4. On the one hand, this arrangement improves the uniformity of the wind flow along the wind outlet direction, reduces the difference in wind flow speed, reduces the generation of turbulence and eddy currents, and further reduces the noise level. Preferably, L5≥L1>L4. As a specific example of the present application, the value of L1 is 13cm~15cm, the value of L2 is 15cm~17cm, the value of L3 is 18cm~24cm, the value of L4 is 10cm~12cm, and the value of L5 is 13cm~15cm.

[0043] As a preferred example of the present application, a second guide arc 602 is provided on the first guide boss 6 on one side close to the second guide groove 8, and a transition arc 15 is provided at the connection between the second air outlet side wall 502 and the first end plate 13. This arrangement further improves the flow of wind, reduces the generation of turbulence and eddy currents, reduces the noise level, and improves the performance of the air conditioning system. Preferably, a first guide arc 601 is provided on the first guide boss 6 at one end away from the second guide arc 602. This arrangement further enhances the overall structural strength of the first guide boss 6.

[0044] As a preferred example of the present application, the second air outlet side wall 502 includes a curved air guide portion 5021 and a cover portion 5022, the cover portion 5022 is arranged at the end of the curved air guide portion 5021 away from the indoor unit body 200, the cover portion 5022 is arranged horizontally, and the first guide boss 6 is arranged on the curved air guide portion 5021.

[0045] This setting not only ensures the air outlet effect, but also further improves the aesthetics and integrity of the panel air outlet structure, thereby increasing user satisfaction with the product.

[0046] As a preferred example of the present application, a foam 16 is provided between the first guide boss 6 and the sealing portion 5022, and the foam 16 is plugged and fixed. A connection gap 17 is formed between the two ends and the end of the foam 16 along the length direction of the first air outlet 5, and the connection gap 17 is not greater than 5 mm. Preferably, the length of the connection gap 17 is 2 mm. By providing the plug-in foam 16 on the inner side of the sealing portion 5022, installation is facilitated to ensure that it is firmly fixed in the corresponding position and is not easy to move or loosen. This arrangement prevents cold air from condensing in the sealing portion 5022 at the air outlet. At the same time, the existence of the connection gap 17 allows the cold air to cool and condense near the sealing portion 5022, which helps to reduce the temperature of the surface of the indoor unit body, reduce the potential generation of condensation droplets, and enhance the user experience.

[0047] As a preferred example of the present application, a guide arc 5011 is provided on the side of the first air outlet 5 formed on the first air outlet side wall 501, near the cover portion 5022. This arrangement further reduces the turbulence effect in the airflow, makes the airflow more stable, reduces noise, improves the stability of indoor air flow, and enhances the user's comfort.

[0048] As a preferred example of the present application, a return air grille 3 is provided at the return air outlet 2 .

[0049] As a preferred example of the present application, the air outlet assembly 4 also includes a second air outlet 9, in which a second guide boss 10 is arranged, and a third guide groove 11 and a fourth guide groove 12 are formed on both sides of the second guide boss 10, wherein the longest side of the second guide boss 10 is L8, the longest side of the third guide groove 11 is L6, and the longest side of the fourth guide groove 12 is L7, L8>L3, L6=L7<L4, and L8>L6+L7.

[0050] The other structures are the same as the air outlet assembly 4 including the first air outlet 5, and will not be repeated here.

[0051] The present application also discloses a ceiling unit, including a panel assembly 100 and an indoor unit body 200, wherein the panel assembly 100 is detachably mounted on the indoor unit body 200, and a panel air outlet structure as described in the above embodiment is arranged on the panel assembly 100, wherein the number of air outlet assemblies 4 including a first air outlet 5 on the panel air outlet structure is one, the number of air outlet assemblies 4 including a second air outlet 9 is three, and the three air outlet assemblies 4 including the second air outlet 9 are arranged adjacent to each other.

[0052] This setting improves the air outlet performance of the panel frame 1 and improves the control and directionality of air flow by arranging at least two air outlet components 4 on the panel frame 1 to meet the specific needs of the air-conditioning system, ensure that the performance of the air outlet components reaches a better working state, and improve the user's comfort.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
