In addition, according to present embodiment, drainage system 60H can be to from inner tube sidewind outlet 101H outflows and in outer tube
20H end (right-hand member in Figure 13) place collides flow path of the air-flow in outer tube 20H after turning back and guided, and can rise
The effect of noise reduction.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that specific implementation of the present utility model is not
Limited by above-mentioned embodiment.
For example, in above-mentioned embodiment 1~9, the outlet of inner tube sidewind is staggered completely with the outlet of outer tube sidewind, but simultaneously
This is not limited to, as long as the outlet of inner tube sidewind is at least partly staggered with the outlet of outer tube sidewind.
In addition, in above-mentioned embodiment 1~4, inner and outer tubes are same footpath straight tube, but are not limited thereto, inner tube
Can also use reducing pipe with outer tube, in addition, can also use inner tube sidewind outlet and/or outer tube sidewind outlet aperture from
The structure that the lateral another side in one end of inner tube is gradually reduced/increased.
In addition, in above-mentioned embodiment 1~9, can also be in outer tube and/or inner tube to reduce the flow noise of air-flow
Inwall stick sound absorber.
In addition, in above-mentioned embodiment 6~9, the outlet of outer tube sidewind can also include two row stagger settings as shown in Figure 5
Perforate, or include the perforate of three row above stagger settings.
In addition, in above-mentioned embodiment 6~9, the outlet of outer tube sidewind also can be as shown in Figure 6, Figure 7 by multiple intensive
Hole forms.
In addition, in above-mentioned embodiment 6~9, can also be set as shown in Figure 8 in the outside of outer tube sidewind outlet with outside
The mozzle of pipe at an angle.
In addition, in above-mentioned embodiment 1~9, airduct both can be integrative-structure, can also according to actual installation demand by
Multistage pipe fitting is spliced, and flexibility is good.Also, in above-mentioned embodiment 6~10, it is spliced in airduct by multistage pipe fitting
When, guide face only is set in the end of final stage airduct.
In addition, in above-mentioned embodiment 1~6, to ensure effect of blowing, preferably by the end of airduct (outer tube) (in Fig. 1
Right-hand member) it is arranged to close.
In addition, in above-mentioned embodiment 1~9, according to actual installation demand or the decoration style of installing space can be coordinated,
The section of pipe fitting is formed as into the shape that any of circle, ellipse, rectangle, trapezoidal, triangle and sector be easy to processing.
In addition, in above-mentioned embodiment 1~9, the shape of outer tube sidewind outlet can be circular, oval, wave
It is any in shape and rectangle.
In addition, the airduct of above-mentioned embodiment 1~9 can be hung and set, hang or be embedded in room according to actual installation demand
The position being arbitrarily adapted to fit.
In addition, use above-mentioned implementation in air treatment system (such as ajutage 7X of the air treatment system shown in Figure 14)
During the airduct of mode 1~9, air-supply uniformity is good, and easy for construction, installation site and mode are flexible.
