Under repeat no more.
Please refer to Fig. 3 and Fig. 4, the noise reduction part 30 include at least one body 33 with two free ends and
The free end of each body 33 is connected and enclosed in the annular groove 22 with being collectively forming a complete circle
Connecting portion 34, each described body 33 has the first side 32 in the laminating annular groove 22, each institute
The windward side for stating body 33 is the sound-absorbing face 31.The body 33 is in strip sheet, and curves through connecting portion 34 and connect into
One complete annulus.The first side 32 refers to the inner ring face of body 33.Air-ducting ring is absorbed by the windward side of body 33
Air-flow at 20 flange 21, by the pressure of the air-flow, speed reduction, reduction, so as to reach substantial noise reduction.
The formation overall design philosophy of noise reduction part 30 is to constitute annulus by the connection of body 33 and connecting portion 34, and specific
Realize that annulus can be using the technical scheme in first embodiment, specifically, the body 33 is one, and the connecting portion 34 is
One, the two free ends that the connecting portion 34 connects the body 33 are enclosed in the annular with forming a complete circle
In groove 22, relative two free ends of the body 33 are when the noise reduction part 30 is enclosed in the annular groove 22 and institute
The center of arc angle for stating the center of circle formation of air outlet 11 is less than 360 degree more than 180 degree.It is curved by a body for strip sheet 33
Song, and the two free ends of body 33 are connected by connecting portion 34 so that body 33 and connecting portion 34 constitute one it is complete
Annulus；Similarly, realize that annulus can be specifically, described please refer to Fig. 6 using the technical scheme in 3rd embodiment
Body 33 is multiple, and the connecting portion 34 is multiple, and each described connecting portion 34 is connected between the adjacent body 33 and common
With enclosing in the annular groove 22, relative two free ends of the body 33 are enclosed located at the ring in the noise reduction part 30
The center of arc's angular region formed with the center of circle of the air outlet 11 when in connected in star 22 for 15 degree to 180 degree, each body 33
The center of arc angle of formation can be with identical, can be with difference.Selected in 15 degree to 180 degree of scope at the center of arc angle of each body 33
Which angle is used, according to setting of the noise reduction part 30 in annular groove 22, is adapted to put the position of one section of body 33 more long, this
The center of arc angle of body 33 is larger, is adapted to put the position of shorter one section of body 33, and the center of arc angle of the body 33 is smaller, and this
The quantity of body 33 can be set according to actual conditions.
For the noise reduction part 30 with connecting portion 34, the connecting portion 34 include pile face (not shown) and tear off or
Hook together in the hooked face (not shown) on the pile face.Specifically, for first embodiment, pile face is connected to body
One in 33 two free ends, hooked face is connected to another in the two free ends of body 33, by hair side
Body closes the connection of the two free ends for realizing body 33 with the hook of hooked face, is torn off mutually between pile face and hooked face, real
The disconnection of the two free ends of existing body 33, when noise reduction part 30 is installed, ring is inserted in by body 33 by the side of air-ducting ring 20
In connected in star 22, then the pile face of connecting portion 34 and hooked face are hooked and is closed, body 33 is tightly fitted in annular groove 22；
For 3rd embodiment, the pile face of connecting portion 34 is connected to the free end of one of body 33, the connecting portion 34
Hooked face be connected to the opposite free ends of adjacent bodies 33 so that the opposite free ends of two neighboring body 33 are connected
Connect, with this, each connecting portion 34 concatenates all bodies 33 to form a complete annulus.
For the noise reduction part 30 with connecting portion 34, the position corresponding to the connecting portion 34 is the noise reduction part 30
At interference with the side portion structure of the front panel 10, if using a complete circle body 33 (i.e. the body 33 is in closed-loop)
It is positioned in annular groove 22, when the side portion structure of the enclosed body 33 and front panel 10 has interference, the nothing of enclosed body 33
Method is used, and in the present invention, the place that enclosed body 33 is interferenceed with the side portion structure of front panel 10 is replaced with connecting portion 34
In generation, can equally realize the purpose of noise reduction, and the noise reduction part 30 that thoroughly need not more renew.
For the noise reduction part 30 with connecting portion 34, the connecting portion 34 can be specially VELCRO.
The concrete structure of noise reduction part 30 can be first embodiment structure, can also be 3rd embodiment structure,
Can be the structure of second embodiment, specifically please refer to Fig. 5, the noise reduction part 30 includes that multiple has two free ends
Body 33, each described body 33 is distributed in the annular groove 22, and each described body 33 has the laminating annular
The first side 32 in groove 22, the windward side of each body 33 is the sound-absorbing face 31.By each independence
Body 33 be distributed in annular groove 22, absorbed by the sound absorption of the windward side of each body 33 and flee from air-ducting ring 20
Flange 21 stream pressure, reduce air velocity, air-flow is weakened, effectively reduce the backflow that is formed at air-ducting ring 20 and
Vortex flow, greatly reduces the noise of air-conditioner inner chamber, particularly the level of noise of each point from all directions, has reached reduction air-conditioner
The purpose of noise and improvement air-conditioner tonequality and sense of hearing comfortableness.
Herein, fitting between each body 33 and annular groove 22 can mutually be glued by tack coat therebetween
Knot, it is possible to understand that ground, it is also possible to which obstructed tack coat is bonding.
For second embodiment, space is formed between the two neighboring body 33, the position corresponding to the space
It is set at the noise reduction part 30 and the interference of the side portion structure of the front panel 10, it is to avoid side of the noise reduction part 30 with front panel 10
Interference between portion's structure.
For second embodiment, each described body 33 is centrosymmetric centered on the center of circle of the air outlet 11
Set, relative two free ends of each body 33 when the noise reduction part 30 is enclosed in the annular groove 22 with
