Ventilating fan 21 is made of centrifugal fan, thus air with towards the form of direction of rotation predetermined oblique angle to radially discharging.

Main body 10 is arranged to the long rectangular shape of lateral length, because of ventilating fan 21 is positioned at the central portion of main body 10, so the length of comparing the 3rd passing away 19 with first and second passing away 17,18 is relative shorter.

Driving according to ventilating fan 21 is tilted towards direction of rotation when discharging to first and second passing away 17,18 flow air, so the air of discharging from first outlet 11 by first passing away 17 is towards the top, and the air of discharging from second outlet 12 by second passing away 18 is towards the below.Therefore, air-flow concentrates on the upside of first outlet 11 and the downside of second outlet 12, in contrast the discharge air-flow of first outlet, 11 downsides and second outlet, 12 upsides relative a little less than.Such air-flow skewness causes the noise of air conditioner inside.

And, because of the 3rd passing away 19 length are shorter than first and second passing away 17,18 relatively, make that the air-flow that directly is discharged from the left side of the 3rd outlet 13 is more relatively, so comparing air quantity with the right side, the left side of the 3rd outlet 13 produces noise greatly.And, direction of rotation airflow flowing (the i direction air-flow of Fig. 1) speed along ventilating fan 21 in the 3rd passing away 19 is very fast, so the phenomenon that extraneous air flows into once more can take place in the part (a part of Fig. 1) more weak relatively at air-flow, especially close on portion's (a part of Fig. 1) in the fin portion on right side and discharge air-flow, dewfall takes place so increased the inflow again of air-flow because of the blocking-up of fin portion.

Therefore, in the present invention in order to prevent that such noise and dewfall are provided with

air conducting parts

71,72,73.

First passing away 17 is provided with the first air conducting parts 71, and the part of air that these first air conducting parts 71 will be discharged with being inclined upwardly guides to the downside of first outlet 11, thereby makes first outlet, 11 region-wide wind speed even.

The first air conducting parts 71 make the flowing of air that concentrates on first outlet, 11 upsides evenly be dispersed to the region-wide of first outlet 11, thereby can not only reduce the noise that the uneven distribution because of air-flow causes, and can also prevent the dewfall phenomenon of first outlet, 11 downsides that air quantity is more weak.And, because the air-flow that first outlet 11 is discharged is passed through in guiding downwards, thereby when being arranged at the air conditioner work on wall top usually, directly provide the air of heat exchange to the user, can improve user's body sense thus.

Identical therewith, second passing away 18 is provided with the second air conducting parts 72, and these second air conducting parts 72 part of air of discharging that will dip down tiltedly guides to the upside of second outlet 12, thereby makes second outlet, 12 region-wide wind speed even.

The second air conducting parts 72 can be provided with a plurality of, and be rightabout streamlined with the first air conducting parts 71, to be used to block to the flowing downward of a part of air-flow of 12 times side flow of second outlet time it is directed to the upside of second outlet 12.

At this, it is also harmless that second outlet 12 is not provided with the second air conducting parts 72.That is, because of the air that is discharged from by second outlet 12 is downward air-flow, so the user that can make usually in the position activity that height is set that is lower than air conditioner feels air-flow at once.

And, be provided with the 3rd air conducting parts 73 at the 3rd passing away 19, to be used at the 3rd outlet 13 region-wide air-flows of discharging equably.

The guide part 19 that is formed on the drawing left side of Fig. 4 among the 3rd air conducting parts 73 and a pair of the 3rd guide part 19a, the 19b closes on, and dips down along the direction of rotation of ventilating fan 21 and tiltedly to be provided with.The portion of air that the blocking-up of the 3rd air conducting parts 73 is flowed from the left side in the 3rd passing away 19 to the right according to being operated in of ventilating fan 21 also is directed to the left side of the 3rd outlet 13 with it.

The 3rd air conducting parts 73 comprise: the base portion 73a that forms the lower end of the 3rd air conducting parts 73; Relative with base portion 73 and form the distributary division 73b of the upper end of the 3rd air conducting parts 73, to be used to shunt the air-flow of discharging along the I direction; Be used to connect the extension 73c of base portion 73a and distributary division 73b.

In one embodiment of this invention, from the base portion 73a of center to the three air conducting parts 73 of ventilating fan 21 apart from d be preferably about 1.1～1.2 times to the distance of ventilating fan 21 radius r, and the line at base portion 73a and ventilating fan 21 centers and can be taken as about 25 °～45 ° by the angle e between the vertical line at ventilating fan 21 centers.

And base portion 73a connects the length direction predetermined oblique angle f of the straight line of distributary division 73b with respect to the 3rd outlet 13, and this predetermined angular can be taken as about 40 °～60 °.

The length of above-mentioned data and the 3rd air conducting parts and highly wait and come to determine by testing according to ventilating fan 21 sizes, main body 10 sizes etc.

Extension 73c between base portion 73a and the cutting part 73b forms the linear pattern that has the streamlined of predetermined curvature or tilt along the direction of rotation of ventilating fan 21 along the direction of rotation of ventilating fan 21, so that extension 73c reaches minimum to the flow resistance of the air-flow that is discharged to the 3rd outlet 13.

Therefore, the 3rd air conducting parts 73 will be directed to the right side of the 3rd outlet 13 obliquely along a part of air-flow that the I direction flows during ventilating fan 21 work, thereby increase the air quantity on the 3rd outlet 13 right sides.Therefore, can prevent to flow into again the right side of the 3rd outlet 13 from the portion of air that discharge in the left side of the 3rd outlet 13, and can in the 3rd outlet 13 region-wide, keep uniform air quantity, thereby can prevent the increase of the noise that causes because of the skewness of discharging air.
