As shown in Table 1 under identical rotation speed of fan, using the air conditioner room unit air quantity comparison of the application volute tongue using existing
There is the air conditioner room unit air quantity of technology volute tongue to have to be obviously improved.
Power, noise comparison under the identical air quantity of table 2.
As shown in table 2 and fig. 4 to fig. 6, it is known that under identical fan delivery, using the air conditioner room unit of the application volute tongue
Comparison is decreased using the air conditioner room unit rotation speed of fan of prior art volute tongue, and level of noise has and is substantially reduced, single-point
Medium-high frequency noise peak also has significant decrease；Under close power of fan, generated level of noise is also substantially reduced.
As depicted in figs. 1 and 2, volute tongue ontology 1 is equipped with the buckle hanging unit 14 connecting with 11 inner surface of windward side, wind-guiding face 12
The one end not connecting with curved sections 13 is equipped with extended segment 15, and buckle hanging unit 14 and extended segment 15 are all subsequent for carrying out volute tongue ontology 1
Machine assembly.In order to guarantee the stability of the assembly of volute tongue ontology 1, buckle hanging unit 14 is set as the bending towards 12 bending of wind-guiding face
Structure, and buckle hanging unit 14 at least two and along the length direction interval of volute tongue ontology 1 be arranged.
Air conditioner room unit as shown in Figure 3, including volute tongue ontology 1, the first spiral case 2, the second spiral case 3, axial-flow fan 4, C
Shape evaporator 5 and panel 6；Wherein, the second spiral case 3 is connected to the bottom end of panel 6, and C-shaped evaporator 5 is arranged in panel 6 and first
Between spiral case 2, axial-flow fan 4 is arranged between C-shaped evaporator 5 and the first spiral case 2；Shape between second spiral case 3 and the first spiral case 2
At the air outlet of air conditioner；Volute tongue ontology 1 is by 14 hanging buckle of buckle hanging unit in one end that the second spiral case 3 is not connect with panel 6, wind-guiding
The extended segment 15 in face 12 and the outer surface of the second spiral case 3 mutually overlap；The vertex of windward side 11 is volute tongue ontology 1 and axial-flow fan 4
Between closest approach, between 11 vertex of windward side of volute tongue ontology 1 and axial-flow fan 4 distance be 5~8mm, it is preferred that volute tongue sheet
It is best to be set as 6mm for distance between 11 vertex of windward side of body 1 and axial-flow fan 4；And the extended segment 15 of wind-guiding face 12 and second
Angle between 3 outer surface of spiral case is preferred within the scope of 0~5 °, i.e., the misalignment angle between wind-guiding face 12 and the second spiral case 3 is not
