Fig. 1 and Fig. 4 is referred to, the snail tongue 100 of embodiment of the present invention is used for air-conditioner 200, and snail tongue 100 includes windward side
10 and wind-guiding face 12.Windward side 10 is used to be oppositely arranged with the wind wheel 210 of air-conditioner 200.Wind-guiding face 12 connects windward side 10.Lead
Wind face 12 is used to extend to the air outlet 212 of air-conditioner 200.Wind-guiding face 12 forms fluted with the junction 14 of windward side 10
16。
In the snail tongue 100 of embodiment of the present invention, because junction 14 forms fluted 16 so that junction 14 and wind wheel
The distance between 210 increases, can weaken impact of the air-flow of the generation of wind wheel 210 to junction 14, such that it is able to reduce air-conditioning
The noise of device 200.
Specifically, when the wind wheel 210 of air-conditioner 200 works, each position of snail tongue 100 can all be produced by wind wheel 210
Air-flow impact, so as to produce noise.
Windward side 10 is oppositely arranged with the wind wheel 210 of air-conditioner 200, and wind-guiding face 12 is used for the air-flow for producing wind wheel 210
The air outlet 212 of air-conditioner 200 is directed to be discharged to outside air-conditioner 200.Between having suitably between windward side 10 and wind wheel 210
Gap so as to backflow phenomenon will not be produced between snail tongue 100 and wind wheel 210, so as to increase the air output of air-conditioner 200；May be used also in addition
To weaken impact of the air-flow to windward side 10, to reduce the noise of the generation of air-conditioner 200.
Therefore, in the case that gap between windward side 10 and wind wheel 210 is constant, forming groove 16 on junction 14 can
To increase the distance of junction 14 and wind wheel 210, thus weaker air-flow to the impact of snail tongue 100 reducing noise.
In some embodiments, groove 16 be strip groove 16, groove 16 along the wind wheel 210 of air-conditioner 200 axial direction
It is continuous to extend.
In embodiment of the present invention, air-conditioner 200 is illustrated by taking hanging air conditioner as an example.It is appreciated that wall-hanging
Air-conditioner 200 is substantially in rectangular-shape.The axial direction of wind wheel 210 is identical with the length direction of hanging air conditioner 200 and wind wheel 210
Preferably tubular wine wheel.Hanging air conditioner 200 offers air outlet 212 in its length direction, therefore, groove 16 is along going out
The length direction in air port 212 extends.So cause air-flow from air outlet 212 flow out when, snail tongue 100 is integrally impacted by air-flow
It is weaker, to reduce noise produced during gas shock snail tongue 100.
Refer to Fig. 2, in some embodiments, the quantity of groove 16 is multiple, multiple grooves 16 along windward side 10 to
The direction interval setting that wind-guiding face 12 extends.
In this way, multiple grooves 16 can cause that multiple positions of junction 14 are subject to the damp impacts of air-flow, such that it is able to
Enter a reduction noise.
In the example of Fig. 2, the quantity of groove 16 is two, it will be understood that in other embodiments, groove 16
Quantity can specifically be set according to actual conditions, for example, three, the other quantities such as four.
It is pointed out that windward side 10 is to the side that the direction that wind-guiding face 12 extends is, for example, dotted arrow instruction in Fig. 2
To.
Referring to Fig. 1, in some embodiments, groove 16 is in arc-shaped.
In this way, the sharp position of groove 16 is less, it is possible to reduce the generation of noise.
In some embodiments, windward side 10 is the arc surface being coaxially disposed with wind wheel 210.
In this way, the fit structure between wind wheel 210 and windward side 10 is compact, be conducive to reducing the body of air-conditioner 200
Product, in addition, so also causing the airflow direction phase that the shape in the gap between wind wheel 210 and windward side 10 is produced with wind wheel 210
Together, impacted by air-flow such that it is able to reduce windward side 10, and then reduced noise.
In some embodiments, it is in arc transition shape at windward side 10 and the link position of groove 16.
In this way, the surface of snail tongue 100 more smooths, be conducive to air-flow along the surface flow of snail tongue 100, to reduce air-flow
Impact to snail tongue 100, so as to reduce the generation of noise.
Air-flow is directed into the air outlet 212 of air-conditioner 200 to improve the air-out of air-conditioner 200 in order to improve snail tongue 100
Efficiency, is in arc transition shape at wind-guiding face 12 and the link position of groove 16 in some embodiments.
In some embodiments, the angle that windward side 10 is formed with wind-guiding face 12 is acute angle.So cause air flow direction
It is diffusion state during the air outlet 212 of air-conditioner 200, is conducive to air-flow to be flowed out from the air outlet 212 of air-conditioner 200.
It should be noted that when windward side 10 and/or wind-guiding face 12 are curved surface, windward side 10 is formed with wind-guiding face 12
Angle refer to：Windward side 10 is sandwiched so that windward side 10 is housed in two the first planes with two parallel the first planes 11
In 11 space, and wind-guiding face 12 is sandwiched so that wind-guiding face 12 is housed in two the second planes with two parallel the second planes 13
In 13 space, the angle α of the first plane 11 and the second plane 13 is the angle that windward side 10 is formed with wind-guiding face 12, such as schemes
Shown in 5.
In some embodiments, snail tongue 100 includes the first snail tongue plate 18 and the second snail being connected with the first snail tongue plate 18
Hyoplastron 20, the first snail tongue plate 18 includes windward side 10, the second snail tongue plate 20 include wind-guiding face 12 and it is opposite with wind-guiding face 12 in
Surface 22, snail tongue 100 includes extending from the space 24 that inner surface 22 is encircled into the first snail tongue plate 18 and the second snail tongue plate 20
Reinforcement 26.
In this way, reinforcement 26 can increase the intensity of snail tongue 100, it is to avoid snail tongue 100 is deformed and influences air-conditioner 200
Air-out effect.
Also referring to Fig. 3 and Fig. 4, the air channel structure 202 of embodiment of the present invention includes housing 204 and any of the above reality
Apply the snail tongue 100 of mode.Housing 204 is formed with air inlet 205, and housing 204 includes chassis 206.Snail tongue 100 is arranged on chassis
On 206, chassis 206 and snail tongue 100 limit the air-out passage 208 that is connected with air inlet 205 and with going out that air-out passage 208 is connected
Air port 212.
In the air channel structure 202 of embodiment of the present invention, because junction 14 forms fluted 16 so that junction 14 with
The distance between wind wheel 210 increases, and can weaken impact of the air-flow of the generation of wind wheel 210 to junction 14, such that it is able to reduce
The noise of air-conditioner 200.
It is pointed out that in present embodiment, snail tongue 100 and chassis 206 are formed in one structure, in other embodiment party
In formula, snail tongue 100 can be arranged on chassis 206 by way of dismounting.
The air-conditioner 200 of embodiment of the present invention includes air channel structure 202, wind wheel 210 and the heat exchange of embodiment of above
Device 214.Wind wheel 210 is arranged in housing 204.Wind wheel 210 is used to suck air to set up air-flow so that gas by air inlet 205
Stream is drained into outside housing 204 from air outlet 212.Heat exchanger 214 is arranged between air inlet 205 and wind wheel 210.
In the air-conditioner 200 of embodiment of the present invention, because junction 14 forms fluted 16 so that junction 14 and wind
Wheel the distance between 210 increases, and can weaken impact of the air-flow of the generation of wind wheel 210 to junction 14, such that it is able to reduce sky
Adjust the noise of device 200.
When air-conditioner 200 works, wind wheel 210 is rotated and sucks air with from air inlet 205, and air is by after heat exchange, passing through
Cross wind wheel 210 pressurize and the guiding of air channel structure 202 after drain into interior from air outlet 212, such that it is able to play adjusting ambient temperature
The effect of degree.
