Embodiment 1

[0036] Embodiment one is basically as attached Figure 1 to Figure 5 Shown:

[0037] The sound-absorbing and sound-insulating device for the outdoor unit of the air conditioner includes a cover 1 covering the external unit 40 of the air conditioner. The cover 1 is fixed on the wall 10 on which the external unit 40 of the air conditioner is installed by expansion screws. The upper and lower ends of the cover 1 are opened, and the cover 1 The lower end opening of the body 1 is an air inlet 11 , and the upper end opening of the cover body 1 is an air outlet 12 .

[0038] combine Figure 4 , the cover body 1 is U-shaped, the cover body 1 includes a left side plate, a right side plate 18 and a front side plate 19, and the left side plate, the right side plate 18 and the front side plate 19 all include a shell, a damping plate 14 and a sound-absorbing material , the housing includes a guard plate 13 and a perforated plate 17 with several through holes, the perforated plate 17 is l...

Embodiment 2

[0053] Example two such as Figure 6 and Figure 7 As shown, Embodiment 2 has been improved on the basis of Embodiment 1, specifically: an opening is provided on the front side plate 19 of the cover body 1, and an access door 2 is fixedly connected to the cover body 1 by screws, and the access door 2 can Cover the opening.

[0054] When it is necessary to maintain the air conditioner external unit 40, only the inspection door 2 needs to be disassembled, and the air conditioner external unit 40 can be overhauled, and the entire air conditioner outdoor unit does not need to be disassembled with the sound-absorbing and sound-insulating device, which ensures the convenience of maintenance .

[0055] In the second embodiment, the inspection door 2 is installed on the front side panel 19, so as to facilitate the inspection and maintenance of the air conditioner external unit 40. At the same time, the inspection door 2 can also be installed on the left side panel or the right side ...
