Embodiment
To describe the embodiment of general plotting of the present invention now in detail, its example shown in the accompanying drawings, wherein, identical label is represented similar elements all the time.Below with reference to the accompanying drawings embodiment is described to explain general plotting of the present invention.
Fig. 2 is the sectional view of ceiling type air conditioner that the turbofan of use general plotting according to the present invention is shown.As shown in Figure 2, this air-conditioning comprises: box body shell 10, be installed in the ceiling board 100, and top board (ceiling plate) 20 is attached on the lower surface that opens wide of body shell 10, and covers the opening of the ceiling board on its circumference.
Body shell 10 is provided with turbofan 40 and drive motor 11 within it, wherein, turbofan 40 is used for by its middle part along the direction that makes progress suction air below air-conditioning, and along radially with air discharging, drive motor 11 is used to drive turbofan 40.Drive motor 11 is fixed on the interior upper surface of body shell 10.In addition, heat exchanger 12 is installed around turbofan 40, with carry out heat exchange from turbofan 40 air discharged.Water of condensation discharge pipe 13 (can collect and be emitted on the water of condensation that produces during the heat exchange) is installed under the heat exchanger 12.Water of condensation discharge pipe 13 is supported by top board 20.
Top board 20 can comprise: inlet 21 upwards sucks indoor air at the middle part of air-conditioning; A plurality of narrow mouths 22 that grow are around inlet 21.In addition, filter member 23 (being used for clean air) can be installed in the inlet 21 of top board 20.Air guide plate 24 is installed in (comprising opening 24a in the middle) inboard of filter member 23, is used for the middle part guiding of inhaled air towards turbofan 40.
To shown in Figure 4, turbofan 40 comprises as Fig. 2: circular swivel plate 41, comprise hub 41a, and the middle part of this hub 41a is attached on the axle 11a of drive motor 11; A plurality of blades 42 are attached on the preceding excircle of swivel plate 41, and along radially being provided with; Ring shield 43 (see figure 4)s, the end relative that is attached to each blade 42 with swivel plate 41.
As shown in Figure 4 and Figure 5, turbofan 40 can form and make the outer diameter D1 of swivel plate 41 be equal to or less than the inner diameter D2 of guard shield 43.
The turbofan 40 of the embodiment of general plotting structure is arranged so that the outer diameter D1 of swivel plate 41 is equal to or less than the inner diameter D2 of guard shield 43 according to the present invention, thereby prevent when the time by the molded turbofan 40 of molding process, undercutting (undercut from the mould generation, for example, molded product can not be by a parallel part that moves moulds and withdraw from), thus swivel plate 41, blade 42 and guard shield 43 can form.
As shown in Figure 5, make the outer diameter D1 of swivel plate 41 less than the inner diameter D2 of guard shield 43 because turbofan 40 forms, can comprise the inner 45 that is attached to swivel plate 41 and the outer end 46 that is not attached to swivel plate 41 so be positioned at the end of each blade 42 of the sidepiece of swivel plate 41.The outer end 46 of each blade 42 that is positioned at the sidepiece of swivel plate 41 can form with respect to swivel plate 41 has pre-determined tilt angle θ.Tiltangle can change to the scope of about 15 degree from about 5 degree.Increase gradually by the distance between the internal surface that makes the outer end 46 of each blade 42 and body shell 10 along with the outer end 46 of each blade 42 along radially outer direction away from the rotating center of swivel plate 41 like this, and can make the minimum of blowing that the eddy current that produced by the outer end 46 around each blade 42 causes.
When turbofan 40 is driven, produce eddy current around the outer end 46 of each blade 42, and this eddy current is along with described outer end 46 is moved and become more and more stronger along radially outer direction.General plotting of the present invention is suitable for making the outer end 46 of each blade 42 and the growth of eddy current to tilt pro rata, thereby but the internal surface of the eddy current minimum degree ground bump body shell 10 that produces around the outer end 46 of each blade 42, thus reduce to blow noise.
Now, will the operation of the ceiling type air conditioner that uses turbofan be described.
As shown in Figure 2, drive drive motor 11, by the centre entrance 21 suction indoor airs of top board 20 so that turbofan 40 is rotated.The indoor air that sucks is cleaned in by filter member 23, and the opening 24a by air guide plate 24 flows into turbofan 40 then.Rotating force by turbofan 40 makes the air rotation and towards the circumference discharging (that is, towards heat exchangers) of turbofan 40.Be cooled in from turbofan 40 air discharged, be supplied to the interior space once more by exporting 22 then by heat exchanger 12.
As shown in Figure 5, as described above with reference to Figure 2, during operation, the air that is blown by turbofan 40 radially is discharged along turbofan 40, and is discharged towards the outer end 46 of each blade 42 that is positioned at swivel plate 41 sidepieces simultaneously.At this moment, the eddy current that produces around the outer end 46 of each blade 42 is along with it moves along radially outer direction, owing to centrifugal force becomes more and more stronger.Because the outer end of each blade 42 46 tilts pro rata with the growth of eddy current,, thereby reduce to blow noise so general plotting of the present invention can make the collision of the internal surface of eddy current and body shell 10 minimize.
As described above in detail, because the growth of the outer end of each of a plurality of blades and eddy current is tilted pro rata, so the turbofan of general plotting can make the eddy current that produces around each outer end of described a plurality of blades and the collision of body shell minimize according to the present invention, thereby can reduce to blow noise.
Though illustrated and described some embodiments of general plotting of the present invention, but those skilled in the art should understand that, under the situation of principle that does not break away from general plotting of the present invention and spirit, can change these embodiments, the scope of general plotting of the present invention is limited by claim and equivalent thereof.
