7 end starts the circumferentially extending front snail tongue 71 along wind wheel 3, is provided with rear spiral case 8 from the end of rear spiral case 8 and starts along wind
The circumferentially extending rear snail tongue 81 of wheel 3, front snail tongue 71 is distributed in the opposite sides of wind wheel 3 with rear snail tongue 81.Jing Internal Experiments are sent out
It is existing, in addition to the position relationship between the heat exchanger 6 and wind wheel 3 of foregoing air intake easily causes noise, in air conditioner chamber
Snail tongue is that another easily affects the position of noise, particularly abnormal squeal-noise before and after in machine.Gas shock is to snail tongue
Clearance backflow between some premenstrual snail tongue 71 and wind wheel 3 afterwards, remainder Jing air outlets flow out.Air-flow is to front snail tongue 71
Shock can produce squeal-noise, it is appropriate increase before the distance between snail tongue 71 and wind wheel 3 can weaken air-flow to front snail tongue 71
Shock, so as to reduce noise.
Wherein, the capacity of returns of the gap location between front snail tongue 71 and wind wheel 3 is related with gap length, and the bigger backflow in gap is more
Greatly, air channel air output is then less, and in order to ensure air output, snail tongue gap can be designed to less distance.But due to front snail tongue
Gap very little between 71 and wind wheel 3, the gas flow rate of backflow is very anxious, can cause sharp noise, the impact to noise total value
It is larger, before the value in gap between snail tongue 71 and wind wheel 3 to weaken squeal-noise on the premise of return loss is reduced
Impact.In a preferred embodiment, between front snail tongue 71 and wind wheel 3 minimum before snail tongue gap a be 4～6mm (preferably

Gap between 71 and wind wheel 3, air-flow is relatively stable such that it is able to further reduce the noise produced by gas shock.
Also, the development length of front snail tongue 71 is 0.4～0.6 times of the radius R of wind wheel 3, in the length range, backflow
Air-flow be enough to gradually be settled out in the clearance space between front snail tongue 71 and wind wheel 3, and be pumped to by wind wheel 3 again
Air outlet, stable reflux airflow can reduce the impact to wind wheel 3, can also reduce the air intake between heat exchanger 6 and wind wheel 3
The interference that air intake air-flow in air-flow adjustment space is produced such that it is able to further reduce noise.The development length of front snail tongue 71
When too short, the air-flow of backflow cannot get enough spaces and is adjusted in the clearance space between front snail tongue 71 and wind wheel 3, gas
Stream is unstable, easily produces impact to wind wheel 3 and increases noise.The development length of front snail tongue 71 can not be long, if front snail
Tongue 71 extends to the clearance space between the 3rd heat exchanger 63 and wind wheel 3, and reflux airflow will disturb the heat exchangers 63 of Jing the 3rd to flow out
Air intake air-flow, be unfavorable for the adjustment of air intake air-flow, noise is increased；And long front snail tongue 71 can also stop the heat exchange of Jing the 3rd
Device 63 flows out and flows to the air-flow of wind wheel 3, causes air turbulence.
Further, in a preferred embodiment, as shown in Fig. 2 rotation of the air-flow near snail tongue 81 along wind wheel 3 afterwards
Turn direction and enter gap between rear snail tongue 81 and wind wheel 3, the starting point of the side of the close wind wheel 3 of rear snail tongue 81 from rear snail tongue 81
(afterwards snail tongue 81 starts to extend from the end of rear spiral case 8, and the starting point of rear snail tongue 81 overlaps with the end of rear spiral case 8) starts gradually remote
From wind wheel 3, specially after snail tongue 81 start gradually to its afterbody contraction from its position be connected with rear spiral case 8 so that snail tongue afterwards
Air-flow near 81 is gradually tightened up at the gap between snail tongue 81 and wind wheel 3 after such that it is able near rear snail tongue 81
Air-flow guide, and slowly current stabilization is carried out to air-flow.Afterwards the rear snail tongue gap c between the starting point of snail tongue 81 and wind wheel 3 with
Snail tongue gap a is consistent before minimum, specially 4～6mm (preferably 4.9mm), so as to ensure that it is enough by space that air-flow has,
To avoid making snail tongue 81 after air-flow intense impact produce the situation of loud noise because rear snail tongue gap c is less.
Also, in the above-described embodiment, (starting point of snail tongue 81 is to rear snail tongue 81 after i.e. for the development length of rear snail tongue 81
The development length of free end) 3～4 times of rear snail tongue gap c are preferably, air-flow is drawn by sufficiently long rear snail tongue 81
