In the second embodiment of window air conditioner equipment of the present invention, such as Fig. 2, Fig. 4, Fig. 6, Fig. 8, Fig. 9 and Figure 10 institute
Show, other than the feature of above-mentioned first embodiment, it includes volute section 20 and volute tongue portion 30, spiral case to further limit spiral case air duct
Portion 20 has against edge 21, against the interior end in contact of edge 21 and exhaust outlet 11, wherein the inner surface of volute section 20 and perpendicular to wind
The middle section intersection for taking turns 40 axis is formed by the molded line 22 that intersecting lens is volute section 20, and molded line 22 has intersection point with against edge 21
Q, from the 111 length F2 of hole wall and wind of line length F1, exhaust outlet 11 with wind wheel 40 apart from nearest point K to intersection point Q on molded line 22
The diameter D of wheel 40 meets 1.8≤(F1+F2)/D≤2.5.
It is worth noting that 111 length of hole wall about exhaust outlet 11, it can be understood as from the hole wall 111 of exhaust outlet 11
With the axial length against 21 contact point of edge to the outer end point of 11 hole wall 111 of exhaust outlet, when shell 10 is located at 11 end of exhaust outlet
When between 11 hole wall 111 of the surface at position and exhaust outlet by rounded corner transition that radius is R, as shown in figure 12, for example, fixed
An endpoint of adopted F2 be exhaust outlet 11 hole wall 111 and the rounded corner cambered surface point of contact P, as shown in Figure 10, F2 another
Endpoint Q can also make identical understanding, certainly, can be by F2 the case where at 11 end position of exhaust outlet without rounding corner structure
Endpoint be defined as the binding site of exhaust outlet 11 hole wall 111 and 10 outer surface of shell.In addition, about on molded line 22 with wind wheel 40 away from
From nearest point K, also as volute section 20 and wind wheel 40 refers to wind wheel 40 as shown in Figure 10 and Figure 11 apart from nearest point K
Axis is that bowlder is made in the center of circle, is formed by point of contact K when tangent with molded line 22 with the tangent smallest circumference w of molded line 22, F1 can be into one
Step is interpreted as 22 line length of molded line from K points to Q points.
In the present solution, return air inlet 12 is located at 11 upside of exhaust outlet, the exit site in spiral case air duct is attached to exhaust outlet 11,
On molded line 22 by further designing volute section 20 from wind wheel 40 apart from nearest point K to molded line 22 and volute section 20 against
Relationship between the 22 length F1 of molded line of 21 intersection point Q of edge, the hole wall 111 length F2 and the diameter D of wind wheel 40 of exhaust outlet 11 is 1.8
≤ (F1+F2)/D≤2.5 may insure that the main water diversion part in volute section 20 is coordinated with 40 size of wind wheel, in air-flow in this way
When entering from return air inlet 12 and flowing to exhaust outlet 11 along spiral case air duct and be discharged, it can be ensured that realize the air-flow in spiral case air duct
Streamline is smooth, smooth, achievees the purpose that reduce pneumatic noise, reduces flow losses, takes into account the noise reduction and energy for promoting product
Effect.
More specifically, when (F1+F2)/D is less than 1.8, in contrast, wind wheel 40 is bigger than normal, 20 fair current effect of volute section
And the practical wind-guiding efficiency of wind wheel 40 is relatively low, the wind-guiding ability of wind wheel 40 is compared with 20 fair current effect of volute section and the reality of wind wheel 40
Wind-guiding efficiency there are relatively large deviation, to obtain mute comfort, needs to greatly reduce 40 rotating speed of wind wheel on matching relationship
And wind pressure, this needs pay highly heat exchange efficiency cost, and can cause wind wheel 40 can not realize noise reduction optimize and
Work in the most efficient rotating speed frequency range of noise reduction so that adjust the noise reduction that the parameters such as wind pressure and wind speed are obtained and unknown
When showing, and working as (F1+F2)/D more than 2.5, wind wheel 40 is less than normal, but the windage in volute section 20 is bigger than normal, and flowing can be caused to damage in this way
It loses and increases, turbulent flow noise increases sharply, and efficiency is caused to reduce；And in the present solution, control F1, F2 and D meet 1.8≤(F1+F2)/D
≤ 2.5, the main water diversion part in volute section 20 keeps a suitable rapport with 40 size of wind wheel, meet wind speed and
Simultaneously, wind wheel 40 can work realizing that noise reduction is optimized in the most efficient rotating speed frequency range of noise reduction wind pressure, and protect
It demonstrate,proves that 20 windage of volute section is small, fair current excellent effect, further promotes flatness, the smoothness of spiral case air duct interior air-flow streamline, reach
To the purpose for reducing pneumatic noise, reducing drag losses, the noise reduction and efficiency for promoting product are taken into account.
Further, as shown in Figure 9 and Figure 10, molded line 22 is located at wind wheel 40 between nearest point K and intersection point Q
Part includes curved section 221 and straightway 222, curved section 221 and straightway 222 along molded line 22 from wind wheel 40 apart from nearest
Point K arrange successively to the direction of intersection point Q, in identical load, air quantity can be promoted, and can be right using curved section 221
