At cavity, wind wheel is mounted on inside cavity, and exhaust outlet is arranged on spiral case, and air intake vent is arranged in cover board, it is characterised in that：The wind
Wheel is the wind wheel of any one described above.
The utility model compared with prior art, has the following effects that：
1) if the utility model includes the dry-air blast that top panel, bottom panel and installation are connected between top panel and bottom panel
Air inlet is arranged in blade among bottom panel, and air duct is formed between adjacent two air blade, and the setting of top panel center connects with motor shaft
The joint seat connect, except the edge of the outer end protrusion bottom panel of the air blade, the circular diameter D1 that the air blade is formed is big
In the diameter D2 of bottom panel, increase the air-out area of wind wheel, the vibration of complete machine can be lowered, to reduce the noise of complete machine；
If 2) edge of the top panel described in is protruding with dry plate auxiliary fan blade, auxiliary fan blade is distributed in top with several air blades
Panel both sides increase enough negative pressure values, moreover it is possible to reduce noise；
3) relational expression of the diameter D2 of the circular diameter D1 and bottom panel formed when air blade：When D2=0.9D1, the wind wheel
Structural improvement effect is best, can effectively improve the efficiency of complete machine, under identical rotating speed, can export bigger static pressure and
Higher air quantity, and the total decibel value of noise of complete machine can reduce by 5 decibel values, and noise improvement is with obvious effects.
