Below in conjunction with Fig. 4, the wind path that blows out from air-ducting ring 201 is described.

1. fan 202 rotates, and from suction inlet 210, sucks and derives by air-ducting ring 201 from the wind that fan 202 blows out;

2. when the wind that blows out of fan 202 was through tapered plane 206 place of water accumulating disc 205, tapered plane 206 places can form eddy current, produce abnormal sound, then blow to evaporimeter 207;

3. the wind (with abnormal sound) that blows out of fan 202 arrives blow-off outlets 209 by evaporimeter 207, then blows to user's family by blow-off outlet 209, and the user can hear abnormal sound (wind is cut sound).

In addition, in patent documentation 1, in order to overcome the problem of above-mentioned abnormal sound, till wind path diffuser (diffuser) extension is set to heat-exchanging chamber 1, thus, the wind that blows out from fan is blown on heat exchanger along the wind path diffuser, has overcome wind and in heat-exchanging chamber, has produced the defect of eddy current, thereby can improve the wind pushing performance of fan, and eliminate abnormal sound.

But in this case, the wind path diffuser is set to the top of water accumulating disc, causes the evaporation of water performance in water accumulating disc to reduce.And need to increase extra parts and go to manufacture, assemble the wind path diffuser, reduced the productivity of air-conditioner.
