Embodiment 1
[0071] In the first embodiment, if Figure 1-Figure 6 As shown, the compressor 1000 is in the figure 1 with figure 2 The conventional structure shown adds the image 3 with Figure 4 The first sound-absorbing partition 32 shown, the combined structure is as follows Figure 5 with Image 6 shown.
[0072]Wherein, the first noise-absorbing baffle 32 is formed in an annular shape and is sheathed on the hub 12 of the bearing 1, and a part of the first silencing baffle 32 is recessed toward a direction away from the bearing 1 to form a groove 31, and the groove 31 is in contact with the bearing. The second end surface f2 of 1 cooperates to define the first sub-muffling cavity P1. The first sub-muffling chamber P1 is formed in an arc shape extending around the center of the first sound-absorbing partition 32 , and two second exhaust holes 30 are provided at the ends of the first sub-muffling chamber P1 . The first muffler 21 is arranged on the first muffler baffle 32 , and a...
Embodiment 2
[0075] In the second embodiment, if Figure 8-Figure 11 As shown, the compressor 1000 is in the Figure 8 with Figure 9 In the traditional structure shown, the first sound-absorbing partition 32 is added, and the combined structure is as follows Figure 10 with Figure 11 shown.
[0076] Wherein, the second muffler 22 is disposed on the first muffler baffle 32 , and the second muffler 22 is provided with two third exhaust holes 20 . Moreover, compared with the first muffler 21 in the first embodiment, the shape of the second muffler 22 is also changed.
[0077] Figure 14 Shown is the inventor's comparative study of compressors without the first noise-absorbing partition 32 and with the first noise-absorbing partition 32, and the curve C in the figure shows that the second muffler 22 combines the first noise-absorbing partition The transmission loss distribution diagram behind the plate 32, the D curve in the figure represents the transmission loss distribution diagram ...
Embodiment 3
[0079] In the third embodiment, the compressor 1000 is Figure 8 with Figure 9 The conventional structure shown adds the Figure 12 The second sound-absorbing partition 33 is shown.
[0080] Wherein, the second noise-absorbing partition 33 is formed in an annular shape and is sheathed on the hub 12 of the bearing 1, and a part of the second noise-absorbing partition 33 is recessed toward a direction away from the bearing 1 to form a groove 31, and the groove 31 is in contact with the bearing. The second end surface f2 of 1 cooperates to define the first sub-muffling cavity P1. The first sub-muffling chamber P1 is formed as a connected circular ring extending around the center of the second muffling partition 33 , and two second exhaust holes 30 are arranged on the second muffling partition 33 .
[0081] Figure 14 It also shows the comparative research conducted by the inventor on the compressors without the second noise-absorbing partition 33 and with the second noise-ab...
