[0057] Figure 1 is a schematic front view of an air outlet panel according to an embodiment of the utility model, as shown Figure 1 As shown, and refer to Figure 2-14 The embodiment of the utility model provides an air outlet panel 100 of an indoor unit of an air conditioner. The air outlet panel 100 includes a plate body 110 , an air outlet area 113 and a first buckle structure 130 .

[0058] The plate body 110 has a front surface 111 and a back surface 112 opposite to each other. The air outlet area 113 is provided with a plurality of air outlet micro holes 120 penetrating the plate body 110. The first buckle structure 130 protrudes backward from the back surface 112 and is located in the air outlet area 113.

[0059] The first buckle structure 130 includes a support seat 131 protruding backward from the back surface 112 and a first buckle 132 protruding from the side wall of the support seat 131. A first avoidance groove 133 with an opening facing backward is provided in the support seat 131, and at least one air outlet microhole 120 is located in the first avoidance groove 133.

[0060] The air conditioner indoor unit 300 may be a cabinet unit, a wall mounted unit, etc. In this embodiment, the air conditioner indoor unit 300 is an air conditioner cabinet unit as an example to illustrate the technical solution of this application.

[0061] Specifically, the air conditioner indoor unit 300 is vertically arranged and may include a front housing 310 , on which an air outlet 320 is arranged, and the air outlet panel 100 is covered on the front side of the air outlet 320 .

[0062] The air outlet panel 100 can be made of plastic and can be manufactured by an integrated molding process. The plate body 110 is flat or curved, preferably the plate body 110 is an arc surface, the convex surface facing forward is the front surface 111, and the concave surface is the back surface 112.

[0063] The middle area of ​​the air outlet panel 100 is set as the air outlet area 113, and the surrounding of the air outlet area 113 can be a connection area 114. A plurality of air outlet micropores 120 are set in the air outlet area 113. The air outlet micropores 120 can be circular holes, rectangular holes, multi-deformed holes, etc., which are not limited here. The size of the air outlet micropores 120 is usually less than 10 mm, preferably less than 5 mm. In this way, the auxiliary air flow can be fully dispersed to avoid the formation of a strong air volume in front of the air outlet panel 100.

[0064] In this embodiment, a first buckle structure 130 is provided on the back surface 112 of the air outlet panel 100, and a third buckle structure 330 corresponding to the first buckle structure 130 can be provided on the front housing 310. Fig.11 As shown, the two are snap-connected so that the air outlet panel 100 is fixedly mounted on the front shell 310 .

[0065] To improve the firmness of the connection, the first buckle structure 130 is disposed in the air outlet area 113. However, the first buckle structure 130 is usually located at a position where an air outlet micro hole 120 is disposed, and the first buckle structure 130 will cover the air outlet micro hole 120, affecting the air outlet panel 100.

[0066] In this embodiment, in order to solve the above problem, a first avoidance groove 133 is provided on the support seat 131 of the first buckle structure 130 to avoid the air outlet micro-holes 120. Specifically, the first avoidance groove 133 opens backwards, and on the back side 112, the groove bottom of the first avoidance groove 133 is larger than the air outlet micro-holes 120, so that the air outlet micro-holes 120 can be set in the groove bottom. In this way, the air outlet airflow of the air outlet 320 can be blown out through the first avoidance groove 133 and the air outlet micro-holes 120, achieving the effect of improving the air outlet uniformity of the air outlet panel 100.

[0067] Preferably, the first buckle structure 130 is integrally formed on the plate body 110. By providing the first avoidance groove 133, shrinkage marks caused by excessive thickness of the support seat 131 can be avoided during injection molding, thereby preventing the formation of a dent on the front surface 111 of the air outlet panel 100, thereby avoiding affecting the structural strength and appearance of the air outlet panel 100.

[0068] In some embodiments of the air outlet panel of the present invention, Figure 1 , Figure 5-6 As shown, the length of the plate body 110 is greater than its width. The air outlet micro-holes 120 are rectangular holes, and the length direction of the air outlet micro-holes 120 is in the same direction as the length direction of the plate body 110 .

[0069] The first avoidance groove 133 is a rectangular groove, and the length direction of the first avoidance groove 133 is in the same direction as the length direction of the air outlet micro-hole 120 .

[0070] In this embodiment, the air outlet 320 is vertically arranged and in an elongated strip shape to form a larger air outlet area and improve the indoor air blowing effect. The air outlet panel 100 is also in an elongated strip shape with a larger aspect ratio.

[0071] Designing the air outlet micro-hole 120 as a vertical rectangular hole can improve the structural strength of the plate body 110 along the length direction. Correspondingly, designing the first avoidance groove 133 as a vertical rectangular groove can reduce the possibility of interference between the support base 131 or the groove wall of the first avoidance groove 133 and the air outlet micro-hole 120 without reducing the structural strength of the support base 131.

[0072] On the other hand, when the first avoidance groove 133 is designed as a vertical rectangular groove, the groove wall of the first avoidance groove 133 can also support the plate body 110, thereby improving the structural strength of the plate body 110 along the length direction.

[0073] In some embodiments of the air outlet panel of the present invention, Figure 5-6 As shown, a plurality of air outlet micro holes 120 are evenly spaced apart along the length direction and the width direction of the plate body 110 .

[0074] The support base 131 is rectangular in shape as a whole, and the length direction of the support base 131 is in the same direction as the length direction of the air outlet micro-holes 120 .

[0075] There are a plurality of first avoidance grooves 133 in each support seat 131, and the first avoidance grooves 133 are arranged at intervals along the length direction of the air outlet micro-holes 120. Each first avoidance groove 133 has at least one air outlet micro-hole 120 therein.

[0076] This embodiment further increases the size of the support seat 131 to further improve the structural strength of the first buckle structure 130 and firmly install the air outlet panel 100 on the front housing 310. Specifically, the support seat 131 is lengthened in the vertical direction, and a plurality of first avoidance grooves 133 are arranged at intervals in the vertical direction. In other words, on the projection surface of the back surface 112, the support seat 131 vertically spans a plurality of air outlet micro-holes 120 and does not cover any of the air outlet micro-holes 120. The structural strength of the first buckle structure 130 is improved without affecting the air outlet of the air outlet panel 100.

[0077] In some embodiments of the air outlet panel of the present invention, Figure 4-5 , Figure 7 and Fig.13 As shown, a connection area 114 is formed around the air outlet area 113 .

[0078] The air outlet panel 100 further includes a slot structure 140, which protrudes backward from the back surface 112 and is located at the junction of the air outlet area 113 and the connection area 114. The slot structure 140 includes a slot 141 and a fixing seat 142 which are adjacently arranged along the length direction of the plate body 110.

[0079] The slot 141 is located in the connection area 114. The slot 141 is used to be plugged and connected to the hook structure 340 of the front housing 310 of the air conditioner indoor unit 300.

[0080] A second avoidance groove 143 with its opening facing backward is disposed in the fixing seat 142 . The second avoidance groove 143 is located in the air outlet area 113 . At least one air outlet micro-hole 120 is located in the second avoidance groove 143 .

[0081] In this embodiment, the slot structure 140 can be located at the upper end of the air outlet area 113 of the air outlet panel 100 and can be integrally formed with the plate body 110. The slot structure 140 has a slot 141 with an upward opening, and the hook structure 340 of the front housing 310 has a downward hook, and the two form a socket connection.

[0082] During installation, first align the upper end opening of the slot 141 of the slot structure 140 with the hook structure 340, and push the air outlet panel 100 upward so that the hook structure 340 is inserted into the slot structure 140. This plug-in connection method can limit the upper end of the air outlet panel 100 in the front-to-back direction and the left-to-right direction.

[0083] In this embodiment, the fixing seat 142 is used to provide a firm support for the slot 141. Part of the fixing seat 142 is in the air outlet area 113, which may block the air outlet micropores 120 and affect the air outlet. For this reason, a second avoidance groove 143 is provided in the fixing seat 142. Specifically, the second avoidance groove 143 opens backward, and on the back side 112, the bottom of the second avoidance groove 143 is larger than the air outlet micropores 120, so that the air outlet micropores 120 can be provided in the bottom of the groove. In this way, the air outlet airflow of the air outlet 320 can be blown out through the second avoidance groove 143 and the air outlet micropores 120, thereby achieving the effect of improving the air outlet uniformity of the air outlet panel 100.

[0084] Preferably, the slot structure 140 is integrally formed on the plate body 110. By providing the second avoidance groove 143, shrinkage marks caused by excessive thickness of the fixing seat 142 can be avoided during injection molding, thereby preventing the formation of a dent on the front surface 111 of the air outlet panel 100, thereby avoiding affecting the structural strength and appearance of the air outlet panel 100.

[0085] In some embodiments of the air outlet panel of the present invention, Figure 4 and Fig.12 As shown, the air outlet panel 100 further includes a card insertion structure 150 .

[0086] The card insertion structure 150 protrudes backward from the back surface 112 and is located in the connection area 114. The slot structure 140 and the card insertion structure 150 are respectively located on both sides of the length direction of the board body 110. The card insertion structure 150 is used to connect the card to the card hole structure 350 of the front housing 310.

[0087] In this embodiment, the card insertion structure 150 may be located in the connection area 114 at the lower side of the air outlet panel 100, and may be integrally formed with the plate body 110. During installation, after the air outlet panel 100 is pushed upward so that the hook structure 340 is inserted into the slot structure 140, the end of the card insertion structure 150 is aligned with the card hole of the card hole structure 350, and the lower end of the air outlet panel 100 is pressed backward or gently tapped so that the end of the card insertion structure 150 is inserted into the card hole and forms a card insertion connection with the card hole structure 350. This card insertion connection method can limit the lower end of the air outlet panel 100 in the front-to-back direction and the left-to-right direction.

[0088] In some embodiments of the air outlet panel of the present invention, Figure 4 and Fig.14As shown, the air outlet panel 100 further includes a transverse limiting rib 160. The transverse limiting rib 160 protrudes backward from the back surface 112 and is located at one end edge in the length direction of the plate body 110. The transverse limiting rib 160 is used to be snap-connected to the second snap-fit ​​structure 360 ​​of the front housing 310.

[0089] In this embodiment, the transverse limiting rib 160 may be located at the upper end of the air outlet panel 100 and may be integrally formed with the plate body 110. During installation, when the air outlet panel 100 is pushed upward so that the hook structure 340 is inserted into the slot structure 140, the rear end of the transverse limiting rib 160 slides past the front of the buckle of the second buckle structure 360 ​​and is buckled into the upper end of the buckle of the second buckle structure 360, that is, the lower end of the transverse limiting rib 160 abuts against the upper end of the buckle of the second buckle structure 360. This buckle connection method can limit the upper end of the air outlet panel 100 in the up and down directions.

[0090] The transverse limiting ribs 160 are also used to improve the structural strength of the upper end of the air outlet panel 100 in the transverse direction, especially the bending strength, so as to avoid or reduce deformation of the air outlet panel 100 .

[0091] In some embodiments of the air outlet panel of the present invention, Figure 4-6 and Fig.11 As shown, the length of the plate body 110 is greater than its width.

[0092] The air outlet panel 100 further includes a first longitudinal limiting rib 171, which protrudes backward from the back surface 112 and extends along the length direction of the plate body 110. Two first longitudinal limiting ribs 171 are arranged at intervals along the width direction of the plate body 110, and are respectively located at the two end edges of the air outlet area 113 along the width direction of the plate body 110.

[0093] A plurality of first buckle structures 130 are fixedly connected at intervals to the side wall of each first longitudinal limiting rib 171 close to the air outlet area 113 .

[0094] In this embodiment, the first longitudinal limiting rib 171 can be integrally formed on the plate body 110. The first longitudinal limiting rib 171 forms the boundary between the air outlet area 113 and the connection area 114 in the lateral direction. On the one hand, the first longitudinal limiting rib 171 can improve the structural strength of the air outlet panel 100, especially improve the bending strength of the air outlet panel 100 along the length direction, and avoid or reduce its deformation.

[0095] On the other hand, the first longitudinal limiting ribs 171 can also prevent the airflow in the air outlet area 113 from flowing out from the lateral ends of the air outlet panel 100 in the lateral direction.

[0096] In this embodiment, by disposing the first buckle structure 130 on the first longitudinal limiting rib 171 , the first buckle structure 130 and the first longitudinal limiting rib 171 can support each other, thereby improving their respective structural strengths.

[0097] Preferably, the first longitudinal limiting rib 171 forms a side wall of the first buckle structure 130 .

[0098] In some embodiments of the air outlet panel of the present invention, Figure 4 As shown, a plurality of air outlet micro holes 120 are evenly spaced along the length direction and the width direction of the plate body 110. Along the width direction of the plate body 110, two adjacent air outlet micro holes 120 are staggered along the length direction of the plate body 110.

[0099] The air outlet panel 100 further includes a transverse reinforcing rib 172, which protrudes backward from the back surface 112 and is located in the air outlet area 113. The transverse reinforcing rib 172 extends along the width direction of the plate body 110 as a whole, and the transverse ends of the transverse reinforcing rib 172 are respectively fixedly connected to the two first longitudinal limiting ribs 171. The transverse reinforcing rib 172 is wavy in shape to separate two adjacent air outlet microholes 120 in the length direction of the plate body 110.

[0100] In this embodiment, two adjacent rows of air outlet microholes 120 are staggered to improve the uniformity of air outlet of the air outlet panel 100. The transverse reinforcing ribs 172 can be integrally formed on the plate body 110 to improve the structural strength of the air outlet panel 100, especially to improve the bending strength of the air outlet panel 100 along the width direction to prevent deformation of the air outlet panel 100.

[0101] The transverse reinforcing ribs 172 are wavy in shape, so as to avoid interference with the air outlet micro-holes 120 and avoid blocking the air outlet micro-holes 120 and affecting the air outlet effect.

[0102] The two ends of the transverse reinforcing rib 172 are respectively fixedly connected to the two first longitudinal limiting ribs 171 , so that the transverse reinforcing rib 172 and the first longitudinal limiting rib 171 can support each other and improve their respective structural strengths.

[0103] The air outlet panel 100 may be provided with a plurality of transverse reinforcing ribs 172 at intervals along the length direction to further improve the structural strength thereof.

[0104] In some embodiments of the air outlet panel of the present invention, Figure 3-4 As shown, the air outlet panel 100 further includes a polygonal reinforcing rib 173, which protrudes backward from the back surface 112 and is located in the air outlet area 113. There are multiple polygonal reinforcing ribs 173, and on the projection surface of the back surface 112, any polygonal reinforcing rib 173 does not intersect with any air outlet microhole 120.

[0105] The polygonal reinforcing ribs 173 may be in a diamond shape, a rectangle shape, etc., and are used to improve the structural strength of the air outlet panel 100 , especially to improve the bending strength of the air outlet panel 100 along the length and width directions to prevent the air outlet panel 100 from deforming.

[0106] The polygonal reinforcing ribs 173 are disposed between the air outlet micro-holes 120 to avoid interference with the air outlet micro-holes 120 and to avoid blocking the air outlet micro-holes 120 and affecting the air outlet effect.

[0107] In some embodiments of the air outlet panel of the present invention, Figure 4 and Fig.11 As shown, the air outlet panel 100 further includes a second longitudinal limiting rib 174, which protrudes backward from the back surface 112 and extends along the length direction of the plate body 110. Two second longitudinal limiting ribs 174 are arranged at intervals along the width direction of the plate body 110, and are respectively located at the two end edges of the plate body 110 in the width direction.

[0108] A snap-fit ​​groove 175 is formed between the first longitudinal limiting rib 171 and the second longitudinal limiting rib 174 on the same side of the width direction of the plate body 110. The snap-fit ​​groove 175 is used to cover the front side of the heat insulation groove 370 on one side of the width direction of the air outlet 320 of the front housing 310.

[0109] The second longitudinal limiting ribs 174 can be integrally formed on the plate body 110 , which can improve the structural strength of the air outlet panel 100 , especially improve the bending strength along the length direction of the transverse ends of the air outlet panel 100 , and avoid deformation of the air outlet panel 100 .

[0110] The clamping groove 175 is covered on the front side of the heat insulation groove 370. On the one hand, the air outlet 320 on the rear side of the air outlet panel 100 can be sealed to prevent airflow from leaking from the lateral sides of the air outlet panel 100. On the other hand, it can form a good heat insulation effect with the heat insulation groove 370 to prevent heat exchange between the airflows on both sides of the heat insulation groove 370, thereby preventing condensation.

[0111] A heat insulating pad may also be disposed in the clamping groove 175 to further enhance the heat insulating effect.

[0112] In some embodiments of the air outlet panel of the present invention, Figure 8 As shown, the air outlet micropores 120 include front micropores 121 opened on the front surface 111 and rear micropores 122 opened on the back surface 112. The bottoms of the front micropores 121 and the rear micropores 122 are connected, the bottom of the front micropores 121 is smaller than the bottom of the rear micropores 122, and the bottom of the front micropores 121 is located inside the bottom of the rear micropores 122.

[0113] In this embodiment, the air outlet micropores 120 are formed by the front micropores 121 opened on the front surface 111 and the rear micropores 122 opened on the back surface 112. During injection molding, convex rib structures for forming the front micropores 121 and the rear micropores 122 are respectively provided on the upper mold and the lower mold, so that even if the thickness of the plate body 110 of the air outlet panel 100 is relatively large, it can be easily demoulded.

[0114] On the other hand, the bottom of the front micropore 121 is smaller than the bottom of the rear micropore 122, so that when the airflow is blown out from the air outlet panel 100, an asymptotic pressurization effect is formed, which can prompt the airflow to be blown out quickly from the air outlet micropore 120 and improve the air outlet effect.

[0115] In particular, since the bottom of the front micropore 121 is inside the bottom of the rear micropore 122, a step is formed around the bottom of the hole. The step can block the condensed water attached to the back side 112 of the air outlet panel 100 from flowing along the hole wall of the air outlet micropore 120 to the front surface 111 of the air outlet panel 100, thereby preventing the user experience from being affected.

[0116] In some embodiments of the air outlet panel of the present invention, Figure 8 and Fig.11 As shown, the length of the plate body 110 is greater than the width. The air outlet panel 100 further includes a longitudinal rib 176 extending along the length direction of the plate body 110, and the longitudinal rib 176 protrudes forward from the front surface 111. There are multiple longitudinal ribs 176, and they are evenly spaced and arranged along the width direction of the plate body 110. The air outlet micropores 120 are all located between two adjacent longitudinal ribs 176.

[0117] In this embodiment, the longitudinal ribs 176 can be integrally formed on the front surface 111. The longitudinal ribs 176 can improve the structural strength of the plate body 110, especially when the length and width of the plate body 110 are relatively large, the longitudinal ribs 176 can effectively improve the bending strength of the plate body 110 along the length direction, and avoid or reduce deformation of the air outlet panel 100.

[0118] On the other hand, since the longitudinal ribs 176 are located on the front surface 111 of the air outlet panel 100 and the air outlet micropores 120 are arranged between two adjacent longitudinal ribs 176, the longitudinal ribs 176 can separate the air outlet areas 113 of two adjacent air outlet micropores 120 in the horizontal direction, thereby preventing the airflows from interfering with each other and forming turbulence after being blown out from two laterally adjacent air outlet micropores 120, thereby improving the uniformity of the air outlet of the air outlet panel 100.

[0119] On the other hand, the utility model also provides an air conditioner indoor unit, the air conditioner indoor unit 300 comprises a front housing 310 and the above-mentioned air outlet panel 100. The front housing 310 is formed with an air outlet 320, and the air outlet panel 100 is covered on the front side of the air outlet 320.

[0120] A third buckle structure 330 buckled to the first buckle structure 130 is disposed in the air outlet 320 .

[0121] In this embodiment, a heat exchange device, a fresh air device, a humidifying device, etc. can be set in the air outlet 320 to form cooling and heating air, fresh air and humidified air respectively, and blow them out evenly from multiple air outlet micropores 120 to meet the diverse needs of users.

[0122] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
