[0056] Figure 1 is a schematic front view of an air outlet panel according to an embodiment of the utility model, as shown in Figure 1 As shown, and refer to Figure 2-15 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 is integrally formed and includes a plate body 200 and air outlet micro holes 300 .

[0057] The plate body 200 has a front surface 210 and a back surface 220 opposite to each other. The air outlet micropores 300 include front micropores 310 provided on the front surface 210 and rear micropores 320 provided on the back surface 220. The bottoms of the front micropores 310 and rear micropores 320 are connected, the bottom of the front micropores 310 is smaller than the bottom of the rear micropores 320, and the bottom of the front micropores 310 is located inside the bottom of the rear micropores 320.

[0058] There are a plurality of air outlet micro holes 300 , which are arranged in an array at intervals along the length direction and the width direction of the plate body 200 .

[0059] The air conditioner indoor unit may be a cabinet unit, a wall mounted unit, etc. In this embodiment, the air conditioner indoor unit is an air conditioner cabinet unit with double air outlets as an example to illustrate the technical solution of this application.

[0060] Specifically, the air conditioner indoor unit is vertically arranged. The air conditioner indoor unit may include a housing 500, on which an air outlet for heat exchange air and an air outlet channel for auxiliary air are arranged. An air outlet panel 100 is arranged on the front side of the air outlet channel for auxiliary air.

[0061] In this embodiment, the air outlet panel 100 can be made of plastic material and manufactured by an integrated molding process. The plate body 200 is flat or curved, preferably the plate body 200 is an arc surface, the convex surface is the front surface 210, and the concave surface is the back surface 220.

[0062] The air outlet micro-holes 300 can be round holes, rectangular holes, multi-deformed holes, etc., which are not limited here. The size of the air outlet micro-holes 300 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.

[0063] By providing a plurality of air outlet micro holes 300 on the plate body 200, auxiliary air such as fresh air or humidified air can be blown out from the air outlet panel 100. Compared with the prior art in which the auxiliary air is blown out from the air outlet, the air outlet panel 100 can avoid excessive air volume at the air outlet, preventing the air outlet from blowing directly on the user and causing discomfort to the user.

[0064] On the other hand, the air outlet panel 100 of this embodiment can reduce the material and weight of the air outlet panel 100 without affecting the strength of the air outlet panel 100 by arranging a plurality of air outlet micropores 300 at intervals along the length direction and the width direction on the plate body 200. During injection molding, the stress concentration problem can be alleviated, thereby reducing the shrinkage dents formed on the front surface 210 of the air outlet panel 100. The effect of improving the structural strength of the air outlet panel 100 and enhancing the beauty of the air outlet panel 100 is achieved. In other words, under the condition of the same material or the same weight, the air outlet panel 100 can form a larger area and is suitable for air conditioners of larger specifications.

[0065] On the other hand, in the air outlet panel 100 of the present embodiment, the air outlet micropores 300 are formed by the front micropores 310 provided on the front surface 210 and the rear micropores 320 provided on the back surface 220. During injection molding, convex rib structures for forming the front micropores 310 and the rear micropores 320 are respectively provided on the upper mold and the lower mold, so that even if the thickness of the plate body 200 of the air outlet panel 100 is relatively large, demoulding can be conveniently performed.

[0066] Furthermore, in the air outlet panel 100 of the utility model, the bottom of the front micropore 310 is smaller than the bottom of the rear micropore 320, so that when the auxiliary wind is blown out from the air outlet panel 100, an asymptotic pressurization effect is formed, which can prompt the auxiliary wind to be blown out quickly from the air outlet micropore 300, thereby improving the air outlet effect.

[0067] In particular, since the bottom of the front micropore 310 is located inside the bottom of the rear micropore 320, a step is formed around the bottom of the hole. The step can prevent condensed water attached to the back side 220 of the air outlet panel 100 from flowing along the hole wall of the air outlet micropore 300 to the front surface 210 of the air outlet panel 100, affecting the user experience.

[0068] In some embodiments of the air outlet panel of the present invention, Figure 6 As shown, from front to back, the area of ​​the front micropore 310 gradually decreases. From back to front, the area of ​​the rear micropore 320 gradually decreases.

[0069] In this embodiment, the front micro-hole 310 and the rear micro-hole 320 are both in an expanded shape, and a constriction is formed at the bottom of the hole. In this way, during injection molding, demoulding of the upper mold and the lower mold can be further facilitated.

[0070] On the other hand, the constriction formed at the bottom of the hole can also improve the distribution of airflow, form a pressurization effect, and improve the air outlet effect.

[0071] In particular, since the hole wall of the rear micropore 320 is arranged obliquely, when condensed water adheres to the hole wall of the rear micropore 320 , the condensed water can flow out backward along the hole wall of the rear micropore 320 to avoid clogging the air outlet micropore 300 .

[0072] In some embodiments of the air outlet panel of the present invention, Figure 1 and Figure 5-6 As shown, the length of the plate body 200 is greater than the width. The air outlet panel 100 further includes a longitudinal rib 410 extending along the length direction of the plate body 200 , and the longitudinal rib 410 is integrally formed on the front surface 210 .

[0073] There are multiple longitudinal ribs 410 , which are evenly spaced along the width direction of the plate body 200 . The air outlet micro holes 300 are located between two adjacent longitudinal ribs 410 .

[0074] The air outlet micro hole 300 is a rectangular hole, and the length direction of the air outlet micro hole 300 is in the same direction as the length direction of the plate body 200 .

[0075] The width L1 of the air outlet micro-hole 300 is 1 / 3-2 / 3 of the distance L2 between two adjacent longitudinal ribs 410 .

[0076] In this embodiment, the longitudinal ribs 410 can improve the structural strength of the plate body 200, especially when the length and width of the plate body 200 are relatively large, the longitudinal ribs 410 can effectively improve the bending strength of the plate body 200 along the length direction, avoiding or reducing deformation of the air outlet panel 100.

[0077] On the other hand, since the longitudinal ribs 410 are located on the front surface 210 of the air outlet panel 100 and the air outlet micropores 300 are arranged between two adjacent longitudinal ribs 410, the longitudinal ribs 410 can separate the air outlet areas of two adjacent air outlet micropores 300 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 300, thereby improving the uniformity of the air outlet of the air outlet panel 100.

[0078] In some embodiments of the air outlet panel of the present invention, Figure 6 As shown, the two long sides of the front side of the air outlet microhole 300 are respectively located on the inclined surfaces of two adjacent longitudinal ribs 410.

[0079] In this way, the airflow blown out through the air outlet micro-holes 300 can be guided by the inclined surface of the longitudinal convex ribs 410, so that the airflow is diffused in the space between two adjacent longitudinal convex ribs 410. In other words, while avoiding mutual interference between the airflows blown out of two adjacent air outlet micro-holes 300, the airflow is guided to diffuse in a limited manner to improve the air outlet effect.

[0080] In some embodiments of the air outlet panel of the present invention, Figure 2 and Figure 4-5 As shown, a plurality of air outlet micro holes 300 are evenly spaced in an array along the length direction and the width direction of the plate body 200. Along the width direction of the plate body 200, two adjacent air outlet micro holes 300 are staggered along the length direction of the plate body 200.

[0081] The air outlet panel 100 further includes a transverse reinforcing rib 420, which is integrally formed on the back surface 220. The transverse reinforcing rib 420 extends along the width direction of the plate body 200 as a whole, and the transverse reinforcing rib 420 is wavy to separate two adjacent air outlet microholes 300 in the length direction of the plate body 200.

[0082] In this embodiment, two adjacent rows of air outlet micropores 300 are staggered to improve the uniformity of air outlet from the air outlet panel 100. The transverse reinforcing ribs 420 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 width direction to prevent deformation of the air outlet panel 100.

[0083] The transverse reinforcing ribs 420 are wavy in shape, which can avoid interference with the air outlet microholes 300 and avoid blocking the air outlet microholes 300 and affecting the air outlet effect.

[0084] The air outlet panel 100 may be provided with a plurality of transverse reinforcing ribs 420 at intervals along the length direction to further improve its structural strength.

[0085] In some embodiments of the air outlet panel of the present invention, Figure 4 and Figure 8-9 As shown, the plate body 200 includes a first end portion 230 and a second end portion 240 spaced apart and arranged opposite to each other along the length direction thereof. The air outlet panel 100 further includes a slide groove structure 430 and a transverse support rib 440 .

[0086] The slide groove structure 430 is integrally formed on the back surface 220 and is located at the first end 230. A first slide groove 431 is formed in the slide groove structure 430, and the first slide groove 431 has a first opening 432 away from the second end 240. An end of the slide groove structure 430 close to the second end 240 is provided with an anti-shrinkage groove 433 and an avoidance groove 434 for avoiding the air outlet micro-holes 300.

[0087] The transverse supporting rib 440 is integrally formed on the back surface 220 and is located at the second end portion 240. The transverse supporting rib 440 extends along the width direction of the plate body 200.

[0088] The walls of the anti-shrinkage groove 433 and the avoidance groove 434 are used to support the slide groove structure 430 to improve its structural strength. The avoidance groove 434 is used to avoid the air outlet micro-holes 300 to avoid blocking the air outlet. The anti-shrinkage groove 433 is used to prevent shrinkage marks from being formed during injection molding, especially to prevent shrinkage marks from being formed on the front surface of the air outlet panel 100, which affects the structural strength and the appearance.

[0089] In this embodiment, the slide groove structure 430 is located at the upper end of the back side 220 of the plate body 200, and a sliding structure 530 corresponding to the slide groove structure 430 may be provided on the housing 500 of the air conditioner indoor unit. Fig.12As shown, the upper end of the air outlet panel 100 is fixedly installed by means of a plug-in connection.

[0090] During installation, first align the first opening 432 of the slide groove structure 430 at the upper end of the air outlet panel 100 with the slide plug structure 530, and push the air outlet panel 100 upward so that the slide plug structure 530 is inserted into the first slide groove 431 in the slide groove structure 430. This plug-in connection method can limit the air outlet panel 100 in the front-to-back direction and the left-to-right direction.

[0091] In this embodiment, the transverse support rib 440 is located at the lower end of the back side 220 of the plate body 200. On the one hand, the transverse support rib 440 can improve the structural strength of the lower end of the plate body 200 and prevent the lower end of the plate body 200 from being deformed. On the other hand, a buckle structure 580 corresponding to the transverse support rib 440 can be provided on the housing 500 of the air conditioner indoor unit, such as Fig.15 As shown, the lower end of the air outlet panel 100 is fixedly installed by a snap connection.

[0092] During installation, after the air outlet panel 100 is slid upward so that the sliding structure 530 is inserted into the first slide groove 431 in the slide groove structure 430, the lower end of the air outlet panel 100 is gently pressed or tapped backward so that the lower end of the transverse support rib 440 slides backward into the buckle structure 580. This buckle connection method can limit the air outlet panel 100 in the vertical direction.

[0093] In this embodiment, the air outlet panel 100 can be conveniently installed on the indoor unit of the air conditioner by providing the slide groove structure 430 and the transverse support ribs 440. The disassembly and assembly process can be performed without the aid of tools, and the disassembly and assembly operation is relatively simple.

[0094] In some embodiments of the air outlet panel of the present invention, Figure 4 and Figure 7 As shown, the air outlet panel 100 further includes a limiting boss 451, which is integrally formed on the back surface 220 and is located at the second end 240. The limiting boss 451 is provided with a mounting hole 452 penetrating the second end 240.

[0095] In this embodiment, the limiting boss 451 is located at the lower end of the back side 220 of the plate body 200, and the housing 500 of the air conditioner indoor unit may be provided with a limiting groove 551 and a threaded hole 552 corresponding to the limiting boss 451. Fig.14 As shown, the lower end of the air outlet panel 100 is fixedly installed by means of a socket connection and a fastener connection.

[0096] During installation, when the air outlet panel 100 is slid upward so that the sliding structure 530 is inserted into the first slide groove 431 in the slide groove structure 430, the limiting boss 451 on the back side 220 of the air outlet panel 100 is slidably inserted into the limiting groove 551 and slides upward along the limiting groove 551. The limiting groove 551 can limit the limiting boss 451 in the left and right directions to prevent the air outlet panel 100 from tilting during the upward sliding process. After the sliding structure 530 is inserted into the first slide groove 431 in the slide groove structure 430, the limiting boss 451 slides upward to the upper end of the limiting groove 551, and the mounting hole 452 and the threaded hole 552 are aligned. Finally, the fasteners can be installed in the mounting hole 452 and the threaded hole 552.

[0097] By providing a fastener connection, it is prevented that a user accidentally touches the transverse support rib 440 and causes the air outlet panel 100 to fall off downward.

[0098] In some embodiments of the air outlet panel of the present invention, Figure 4 and Fig.10 As shown, the air outlet panel 100 further includes a hook structure 460, which is integrally formed on the back surface 220. In the length direction of the plate body 200, the hook structure 460 is between the first end 230 and the second end 240, and the hook structure 460 faces the first end 230. There are multiple hook structures 460 arranged at intervals along the length direction and width direction of the plate body 200.

[0099] In this embodiment, the hook structure 460 is located on both lateral sides of the back side 220 of the plate body 200, and a slot structure 560 corresponding to the hook structure 460 can be provided on the housing 500 of the air conditioner indoor unit. Fig.13 As shown, the middle part and the two lateral sides of the air outlet panel 100 are fixedly installed by means of a socket connection.

[0100] During installation, first align the hook of the hook structure 460 with the opening of the corresponding slot structure 560, and push the air outlet panel 100 upward so that the hook of the hook structure 460 is inserted into the slot structure 560. This plug-in connection method can limit the air outlet panel 100 in the front-to-back direction and the left-to-right direction.

[0101] In some embodiments of the air outlet panel of the present invention, Figure 4-5 As shown, the length of the plate body 200 is greater than the width. The air outlet panel 100 further includes a snap-in slot 470 extending along the length direction of the plate body 200 , and the snap-in slot 470 is integrally formed on the back surface 220 .

[0102] There are two snap-fitting grooves 470 , which are arranged at intervals along the width direction of the plate body 200 . In the width direction of the plate body 200 , all the air outlet micro-holes 300 are located between the two snap-fitting grooves 470 .

[0103] In this embodiment, the snap-in groove 470 is located on both sides of the plate body 200 in the horizontal direction, which can improve the structural strength of the air outlet panel 100, especially when the length and width of the air outlet panel 100 are relatively large, thereby improving the bending strength of the air outlet panel 100 along the length direction and avoiding or reducing deformation of the air outlet panel 100.

[0104] The snap-in groove 470 is also used to snap-in connect with the snap-in plate on the housing 500 of the air conditioner indoor unit, thereby sealing the auxiliary air outlet channel on the rear side of the air outlet panel 100 to prevent the auxiliary air from leaking from both sides of the air outlet panel 100.

[0105] In some embodiments of the air outlet panel of the present invention, Figure 3-4 and Figure 7 As shown, the air outlet panel 100 further includes a guide rib 480, which is integrally formed on the back surface 220. The guide rib 480 is arranged along the width direction of the plate body 200, and the two ends of the guide rib 480 are fixedly connected to the two clamping grooves 470 respectively.

[0106] The guide ribs 480 are located at the lower side of all the air outlet micro holes 300 , and the rear end of the guide ribs 480 forms the rear end of the air outlet panel 100 .

[0107] On one hand, the guide ribs 480 can improve the structural strength of the air outlet panel 100 .

[0108] On the other hand, condensed water, dust and other debris may adhere to the back 220 of the air outlet panel 100 and flow downward along the back 220 of the air outlet panel 100. By providing the guide ribs 480 at the lower part of the air outlet panel 100, condensed water can be prevented from flowing out from the lower end of the air outlet panel 100, affecting the user experience.

[0109] Preferably, the guide rib 480 can be arranged to be tilted backward. Since the rear end of the guide rib 480 is the rear end of the air outlet panel 100, the condensed water on the guide rib 480 can fall into the water receiving tray of the air-conditioning indoor unit after flowing down from the rear end of the guide rib 480, thereby preventing the condensed water from flowing out from the front side of the air-conditioning indoor unit.

[0110] In some embodiments of the air conditioner indoor unit of the utility model, the air conditioner indoor unit includes a shell 500 and an air outlet panel 100 of any one of the above embodiments or a combination of embodiments, the shell 500 is provided with an air outlet channel, and the air outlet panel 100 is covered on the air outlet channel.

[0111] In this embodiment, a humidifying device, a fresh air device, etc. may be provided in the air outlet channel for blowing out auxiliary air.

[0112] 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.
