Next, the action effect played in air conditioner 500 is in FIG described.Figure 15 is the figure of the blowout stream be shown schematically in from back side blow-off outlet to indoor in the air conditioner in Fig. 1.Figure 16 is the figure represented after the scope of being surrounded by double dot dash line XVI in Figure 15 being amplified.
With reference to Figure 15 and Figure 16, in the air conditioner 500 of present embodiment, generation comprises the blowout stream of main flow 510 and eddy current 520 (the centre of gyration axle of eddy current 520 becomes the direction of the flow direction along main flow 510) as the blowout stream from back side blow-off outlet 18 to indoor, above-mentioned eddy current 520 flows along main flow 510, has swirl components.
The air (the air stream shown in arrow 521) flowed to the direction identical with main flow 510 in blow-off outlet 18 overleaf collides with the 1st face 76 of swirl component generating unit 75, and the shape that erects along the 1st face 76 flows (the air stream shown in arrow 522).(peeling off from the 1st face 76) air that wherein cannot flow along the 1st face 76, when crossing crest line 78, flows in the mode at the edge being involved in crest line 78.Thus, the swirl component (air stream arrow 523 shown in) different from main flow 510 is produced in main flow 510 side.The swirl component of such generation, after being blown from back side blow-off outlet 18, becoming eddy current 520 and flows to the direction identical with main flow 510.
Figure 17 is shown schematically in the figure from the velocity potential of the air stream of back side blow-off outlet blowout in the air conditioner in Fig. 1.Figure 18 is shown schematically in the velocity potential figure from the air stream of back side blow-off outlet blowout in the air conditioner for comparing.In figure 18 in the air conditioner that compares, blow-off outlet 18 does not arrange the swirl component generating unit 75 shown in Figure 15 and Figure 16 overleaf.
With reference to Figure 17 and Figure 18, eddy current 520 can give new kinetic energy to main flow 510 and the boundary layer around it, can arrive at a distance by giving rotation.In addition, the decay of eddy current 520 is comparatively slow, therefore prevents main flow 510 from being lured air-flow (being taken into the air-flow in main flow region 530 from peripheral region 540) to corrode.Thus, the gesture core (maximum of wind components) maintaining main flow 510 is also easy in the position away from back side blow-off outlet 18.Thereby, it is possible to suppress the decay of the speed of main flow 510, the range of main flow 510 can be extended efficiently.

In addition, in the present embodiment, the 1st face 76 forming the outward appearance of swirl component generating unit 75 is made up of flexure plane.According to above-mentioned formation, swirl component generating unit 75 can be suppressed to become the resistance of main flow 510 and tackle air stream, more effectively can obtain the effect brought by eddy current 520.And, suppress while the rotating speed of Air Blast fan 4 can not be improved the reduction of the wind speed of back side blow-off outlet 18, dust suction speed can be made more efficiently to increase.In addition, the wind speed of back side blow-off outlet 18 not easily reduces, and the range of main flow 510 extends, and therefore can also improve the burst size of ion.
In addition, in the present embodiment, the long side direction of swirl component generating unit 75 opening surface of blow-off outlet 18 overleaf forms constriction shape, blowout area reduces.By above-mentioned formation, from the wind speed rising of the main flow 510 that back side blow-off outlet 18 blows out, therefore, it is possible to extend its range further.
In addition, when the total length L of the minimum length x of the stream of the long side direction of the opening surface of blow-off outlet 18 and the stream of long side direction meets the relation of x/L≤0.9 overleaf, swirl component can be produced more reliably in main flow 510 side, the wind speed of main flow 510 can be maintained by this vortex flow ground.In addition, when the minimum length x of stream of long side direction of opening surface of top blast the outlet 18 and total length L of the stream of long side direction meets the relation of 0.6≤x/L, the minimizing of the air quantity of back side blow-off outlet 18 can be suppressed for Min., and dust suction speed can be improved efficiently.
In addition, in the present embodiment, swirl component generating unit 75 is located at blinds 7.According to above-mentioned formation, the adjustment of wind speed can be carried out by the gradient changing blinds 7, can according to use occasion by dust suction speed optimization.In addition, the flow direction of swirl component can be made closer to the flow direction of main flow 510 in blow-off outlet 18 overleaf.Thereby, it is possible to make stronger swirl component flow along main flow 510, the decay of the speed of main flow 510 can be suppressed efficiently.
According to the air conditioner 500 of the embodiments of the present invention 1 formed like this, can by being produced the decay that swirl component suppresses the speed of main flow 510 by swirl component generating unit 75.Thereby, it is possible to suppress the reduction of dust collecting capability and realize the raising of dust suction speed.

With reference to Figure 27 to Figure 30, in any one situation, air quantity when being all same rotating speeds of Air Blast fan 4 is slightly large in embodiment 1 compared with embodiment 2.The R shape of the swirl component generating unit 75 of embodiment 1 is the shape being suitable for improving wind speed a little, air quantity being increased further, preferentially can improve dust collecting capability by increasing air quantity.
Figure 31 to Figure 34 is the coordinate diagram representing the rotating speed of Air Blast fan and the relation of wind speed in example 2.
In the present embodiment, when the Opening length of blow-off outlet 18 is 75mm (during standard-sized sheet), 45mm, 35mm and 30mm overleaf, the rotating speed of Air Blast fan 4 is changed and is leaving the maximum wind velocity of width of position measurement blowout stream of 50cm from the opening surface of top blast outlet 18 to short transverse, its result is represented in Figure 31 to Figure 34 (Figure 31: during standard-sized sheet, Figure 32: 45mm time, Figure 33: 35mm time, Figure 34: 30mm time).

In the present embodiment, when using that the air conditioner (swirl component generating unit 75 is R shapes) of embodiment 1, the power consumption of Air Blast fan 4 are 52W, the Opening length of back side blow-off outlet 18 is 75mm (during standard-sized sheets), the minimum length x of the stream of the long side direction of the opening surface of back side blow-off outlet 18 is changed, and determines each performance (the total length L of the stream of long side direction is 225mm) of dust suction speed, dust collecting capability and air cleaning ability.
With reference to Figure 43 to Figure 45, about dust suction speed, when x/L lower than 0.9 time accelerate sharp, when lower than 0.7 time can not change significantly thereafter.The power consumption of Air Blast fan 4 is fixing, and therefore when reducing back side blow-off outlet 18, because the pressure loss increases, so air quantity reduces, the load of Air Blast fan 4 diminishes, and the rotating speed of Air Blast fan 4 increases.Consequently, air quantity reduces, but maintains wind speed.
About dust collecting capability (air quantity), compared with the situation (x/L=1) that swirl component generating unit 75 is not set, be equal above until x/L is lower than 0.6, when x/L lower than 0.6 time, become the result reduced sharp.More reduce back side blow-off outlet 18 dust collecting capability more to reduce, wind speed accelerates, and therefore extends the range of blowout stream, inhibits the reduction of dust collecting capability to a certain extent.
About air cleaning ability, by be benchmark with the situation not arranging swirl component generating unit 75, number that the dimensionless number of dust collecting capability obtains divided by the dimensionless number of dust suction speed is decided to be air cleaning ability, is set to the desired value represented as the overall performance of air cleaner.The value of air cleaning ability is that large value is until x/L is lower than 0.585 compared with not arranging the situation of swirl component generating unit.The peak value of air cleaning ability is near x/L=0.7.According to above content, confirm in the scope till x=0.6L degree and improve air cleaner performance.
