[0002] The outdoor unit of an air conditioner usually includes a shell and components such as a fan and a compressor arranged in the shell. The operation of the fan drives the air in the shell to flow toward the air outlet on the shell, and then is discharged to the outside of the shell. However, the outdoor unit of the air conditioner is noisy and has a single appearance, which has always been a problem in the industry. Pang Feng's "Research on the Influence of Mesh Cover, Wind Wheel, and Air Guide Ring on Air Volume Noise of Air Conditioner Outdoor Unit" explains the relationship between the length of the air guide ring and the noise of the outdoor unit. It points out that increasing the length of the outdoor unit wind ring is beneficial to increase the air volume and reduce the noise of the outdoor unit. However, lengthening the air guide ring is limited by sheet metal materials and processing technology. Moreover, the outer shell of a traditional outdoor unit is generally made of sheet metal. Limited by the sheet metal material and processing technology, the appearance of the outdoor unit generally does not change much, which can easily cause aesthetic fatigue among consumers.

[0038] like Figures 1 to 7 As shown, the present invention discloses an external machine panel comprising:

[0039] The panel lining plate 2 has an air outlet 21 formed thereon, and the edge of the air outlet 21 extends backward to form a lining plate air guide ring 22;

[0040] The plastic panel 1 is detachably arranged in front of the panel lining 2. A panel air guide ring 11 is protruding backward on the back of the plastic panel 1. The panel air guide ring 11 is connected with the lining air guide ring 22. A plurality of air outlet holes 12 for air outlet are opened on the plastic panel 1, and the positions of the air outlet holes 12 correspond to the air outlet 21.

[0041] The present invention designs the external unit panel into a form of a plastic panel 1 combined with a panel lining 2, so that the external unit panel has good appearance expandability. The appearance of the external unit panel can be adjusted by replacing the plastic panel 1 to meet the aesthetic needs of consumers. At the same time, since the panel air guide ring 11 connected with the lining air guide ring 22 on the panel lining 2 is provided on the back of the plastic panel 1 in the present invention, the air guide ring of the external unit panel is lengthened, thereby achieving the gain effect of increasing the air volume and reducing the noise, and is not limited by the sheet metal material and processing technology.

[0042] like Figure 4 and Figure 6 As shown, the panel liner 2 is provided with a plurality of plug holes 23, and the back of the plastic panel 1 is provided with a plurality of buckles 13 adapted to the panel liner 2, and the plastic panel 1 is detachably mounted in front of the panel liner 2 through the buckles 13 and the plug holes 23. Generally speaking, the plurality of buckles 13 are evenly arranged around the panel air guide ring 11 and around the plastic panel 1, so that the plastic panel 1 and the panel liner 2 can be tightly mounted, especially the panel air guide ring 11 can be tightly attached to the panel liner 2, so as to prevent a gap between the two from affecting the air volume and noise.

[0043] like Figure 5 As shown, the buckle 13 includes a buckle head 131 and a connecting portion 132. The buckle head 131 is connected to the back of the plastic panel 1 through the connecting portion 132. A slot 133 that can be clamped on the socket 23 is formed between the buckle head 131, the connecting portion 132 and the plastic panel 1, and the opening of the slot 133 is set downward.

[0044] A guide slope is provided on the side of the buckle head 131 close to the plastic panel 1, a clamping rib 134 is provided between the connecting portion 132 and the plastic panel 1, and a guide slope is provided on the side of the clamping rib 134 close to the buckle head 131. The width of the lower part of the socket 23 is smaller than the width of the upper part of the socket 23, and the lower part of the socket 23 is connected to the upper part of the socket 23 by a ramp transition, and the width of the lower part of the socket 23 is equivalent to the width of the buckle 13. In this way, the smoothness of the buckle 13 when the socket 23 is inserted into the socket 23 can be improved, and the production efficiency can be improved. In addition, since the width of the lower part of the socket 23 is equivalent to the width of the buckle 13, after the buckle 13 is inserted into the socket 23, the socket 23 can limit the left and right directions of the buckle 13. Furthermore, the width of the card slot 133 is equivalent to the thickness of the panel lining 2, so that the socket 23 can limit the front and rear directions of the buckle 13.

[0045] Since the plastic panel 1 has a certain thickness and there is a panel air guide ring 11, there is a gap between the plastic panel 1 and the panel lining 2 when the plastic panel 1 is assembled. The back of the plastic panel 1 is also convexly provided with a plurality of support ribs 14 and a plurality of reinforcing ribs 15. The support ribs 14 are provided to support the plastic panel 1 to prevent the plastic panel 1 from deforming and collapsing due to stress, and the reinforcing ribs 15 are provided to increase the strength of the plastic panel 1 itself.

[0046] A plurality of air-dispersing pieces 111 are arranged inside the circumference of the panel air-guiding ring 11, one end of the air-dispersing piece 111 is connected to the panel air-guiding ring 11, and the other end is a free end facing the center of the panel air-guiding ring 11, so as to better reduce noise and increase air volume.

[0047] In order to improve the smoothness of air outlet, the length of the panel air guide ring 11 is not less than 10 mm, the diameter of the panel air guide ring 11 is D, the diameter of the lining air guide ring 22 is d, Dd≥4 mm, so that the air outlet interface of the air conditioner outdoor unit becomes wider and wider.

[0048] like Figure 1 and Figure 2 As shown, the present invention also discloses an air conditioner, comprising an external unit body 3, a top cover 4 and an external unit panel as described in any one of claims 1 to 8, wherein a panel lining 2 is installed in front of the external unit body 3, a plastic panel 1 is detachably arranged in front of the panel lining 2, wind generated by a fan in the external unit body 3 is blown out in sequence through an air outlet 21 on the panel lining 2 and an air outlet 12 on the plastic panel 1, and the top cover 4 is installed on top of the external unit body 3 and the panel lining 2.

[0049] The back of the plastic panel 1 is also provided with a convex limiting rib 16, which is arranged at the upper part of the back of the plastic panel 1 along the length direction of the plastic panel 1; the front of the panel lining 2 is provided with a limiting platform 24, which is arranged at the upper part of the front of the panel lining 2 along the length direction of the panel lining 2; the top cover 4 is provided with a flange 41 around it to improve the strength and rigidity of the top cover 4, making the assembly more reliable. The flange 41 located on the front side of the top cover 4 is partially recessed to form a limiting groove 411 opening downward; when the plastic panel 1, the panel lining 2 and the top cover 4 are assembled, the limiting rib 16 of the plastic panel 1 is placed on the limiting platform 24 of the panel lining 2, and the bottom of the limiting groove 411 on the top cover 4 is against the limiting rib 16 of the plastic panel 1, thereby limiting the plastic panel 1 in the up and down directions.

[0050] Air volume and noise experiment of air conditioner outdoor unit:

[0051] When the length of the panel air guide ring 11 of the plastic panel 1 is 20 mm, it is set as Example 1; when the length of the panel air guide ring 11 of the plastic panel 1 is 0 mm, it is set as Comparative Example 1. Under the conditions of different fan speeds, the air volume and noise of the air conditioner outdoor unit in Example 1 and Comparative Example 1 are tested, and the test results are shown in Table 1 below:

[0052] Table 1: Test results of the air volume noise of the air conditioner outdoor unit under different fan speed conditions in Example 1 and Comparative Example 1

[0053]

[0054] It can be seen from Table 1 that, taking the extension of the wind coil by 20mm as an example, under the same voltage and fan speed, the air volume increases by 85 to 100 cubic meters after the wind coil is extended by 20mm, and the noise decreases by about 1dB under the same air volume, which is a significant benefit.
