When air conditioner does not operate, outlet 10 changes blade 14 by upper and lower wind direction and closes, as shown in Fig. 6 A and 6B.During cooling, preferably, boot up the cold air of discharging from air conditioner, for this purpose, control upper and lower wind direction and change blade 14 to be located at the position between the complete release position shown in the centre position shown in Fig. 7 A and 7B and Fig. 8 A and 8B, or swing up and down between centre position and complete release position.On the other hand, when starting to heat, upper and lower wind direction is changed blade 14 and remains on the complete release position scheduled time shown in Fig. 8 A and 8B, and once make thermal-stable, just upper and lower wind direction is changed blade 14 and remain on the centre position shown in Fig. 7 A and 7B to control to discharge from the warm air of air conditioner discharge downwards.
When upper and lower wind direction change blade assembly 12 is rotated upwardly to the position of Fig. 8 A and 8B from the position of Fig. 7 A and 7B, left and right wind direction changes the part of the bottom adjacent to outlet 10 of blade 14 and fan guard 2 generally parallel along the direction shown in arrow A from upstream side lateral movement towards downstream.As a result, left and right wind direction changes the primary stream portion that blade 14 is always positioned at the air will discharged from outlet 10.The term " primary stream portion " adopted in whole the application is defined as such part of air stream 5: at this part place, and left and right wind direction changes blade 14 makes the air will discharged from outlet 10 bend at left and right directions the most efficiently.That is, primary stream portion is arranged in the downstream of the air flue 6 of air conditioner.
The action that left and right wind direction changes blade 14 is depended on: the distance between the cross bar rotating shaft 21 of support rail 15 and the guide finger 23 of guide plate 22, guide plate 22 is relative to the setting angle of support rail 15, and the shape of gathering sill 30.Namely, when upper and lower wind direction change blade 24 rotates up, support arm 25a, 25b, 25c, 25d, 25e, 25f rotate around rotating shaft 27, and the left and right wind direction that cross bar rotating shaft 21 is rotatably inserted into respective support hole 26 in support arm 25a, 25b, 25c, 25d, 25e changes blade assembly 13 moves towards downstream relative to the direction of air stream 5 while rotary bar rotating shaft 21.Because guide finger 23 is connected to one of cross bar rotating shaft 21 via guide plate 22 and inserts in the gathering sill 30 of central support portion 28, thus guide finger 23 motion of following the rotation of cross bar rotating shaft 21 by gathering sill 30 shape controlling and cause guide finger 23 to move along gathering sill 30.The motion of guide finger 23 is as shown in Fig. 6 B, 7B and 8B.
Namely, left and right wind direction changes the shape controlling of motion path by gathering sill 30 of blade assembly 13, therefore, the shape can moved towards downstream along the direction that the part of the bottom adjacent to outlet 10 with fan guard 2 is substantially parallel by gathering sill 30 being formed as make left and right wind direction change blade 14, makes left and right wind direction change blade 14 and does such motion.When there is no gathering sill 30, when upper and lower wind direction change blade assembly 12 rotate to the state of Fig. 7 B from the state of Fig. 6 A time, left and right wind direction changes blade 14 by the position shown in the double dot dash line that moves in Fig. 7 A.
Illustrate that left and right wind direction changes the angle change of blade 14 hereinafter with reference to Fig. 4,9 and 10.Fig. 9 describes the state that air is discharged forward from air conditioner, and Figure 10 describes the state that air is discharged from air conditioner to the right.
When the motor 38 held in vane drive mechanism 33 in the direction of arrow B actuating arm 36 time, the sliding axle 32 being connected to arm 36 slides in the same direction together with connector 34, and wherein connector 34 to be rotatably installed on sliding axle 32 but can not to slide relative to sliding axle 32.Because connector 34 is clipped between two isolated near-ends of connector 35 on the evagination axle 31 of support rail 15, connector 35 slides together with arm 36 with connector 34, sliding axle 32.
Because be fastened to the pin 16a connecting cross bar 16 to insert in the otch 35a in connector 35, slide in the direction of arrow B together with connector 35 so connect cross bar 16.Figure 10 describes the state that connection cross bar 16 has moved in the direction of arrow B.As shown in Fig. 4 (b), pin 16a has the annular stop 16b formed at its far-end and is separated from pin 16a to prevent connector 35.
Connecting cross bar 16 makes the left and right wind direction change blade 14 being rotatably connected to connection cross bar 16 via movable axis 20 rotate around each fixed axis 18 relative to the slip of support rail 15.As shown in the double dot dash line in Figure 10, the pin 16a connecting cross bar 16 rotates to depict an arc around rightmost one (in Figure 10 leftmost one) fixed axis 18, and therefore together with connector 35 along the direction movable length L2 vertical with the direction of arrow B, simultaneously along the direction sliding length L1 of arrow B.Due to this reason, the otch 35a in connector 35 extends (see Fig. 4 (b)) on the direction vertical with the direction of arrow B.
Connector 34, connector 35 etc. form bindiny mechanism, and via this bindiny mechanism, vane drive mechanism 33 makes sliding axle 32 and is connected cross bar 16 and moves together.Needs to connector 34 are described hereinafter.
Be coupling in batter 35b assuming that replace the evagination axle 31 of support rail 15 to be rotatably received in two of connector 35 at the situation downslide moving axis 32 not arranging connector 34, and the pin 16a that supposition connects cross bar 16 inserts in the otch 35a in connector 35.Because connect cross bar 16 change the rotation of blade assembly 12 along with upper and lower wind direction and rotate, so the position that connection cross bar 16 changes the rotating shaft 27 of blade assembly 12 relative to sliding axle 32 or upper and lower wind direction changes as illustrated in figs. 6 a and 7, and the distance L3 between the longitudinal center line of the movable axis 20 of the longitudinal center line of rotating shaft 27 and left and right wind direction change blade 14 also changes.Although the change of distance L3 can be accommodated by the otch 35a in connecting piece for lengthening 3, but connect the angle of cross bar 16 in the face of the surface of connector 35 relative to the evagination axle 31 of support rail 15 and very large change occurs, as shown in the C in Fig. 6 A or 7A, due to this reason, the connector of the shape identical with the shape of connector 35 can not be used.In order to overcome this problem, evagination axle 31 and sliding axle 32 are connected to each other via connector 34, and evagination axle 31 is connected to connection cross bar 16 via connector 35.By doing like this, angle changes C and is accommodated by connector 34, therefore, connects cross bar 16 and always keeps parallel in the face of the surface connecting cross bar 16 with connector 35.Therefore, change during blade 24 rotates at upper and lower wind direction and can not disturb between connector 35 and connection cross bar 16, thus allow to connect cross bar 16 Smooth Rotation and allow connection cross bar 16 smoothly to slide together with connector 35.
Above-mentioned structure allows when air-conditioner operation, the primary stream portion that left and right wind direction change blade 14 is always positioned at air stream 5 sentences the angle just effectively changing left and right wind direction change blade 14, and no matter how upper and lower wind direction changes the position of blade 24, thus make it possible to improve heat pump performance.The angle that left and right wind direction changes blade 14 changes and can be automatically performed by vane drive mechanism 33.
Although the large change of the angle C shown in Fig. 6 A or 6B caused by the high rotation angle degree changing blade 24 due to upper and lower wind direction in the above-described embodiments and arrange connector 34, if but the anglec of rotation of wind direction change blade 24 is less (such as up and down, if up and down wind direction change blade 24 only swing between the state of Fig. 7 A or 7B and the state of Fig. 8 A or 8B and need not closed row export 10 thus allow to be connected cross bar 16 and connector 35 engages with leaving nargin each other), also can save connector 34.
The pendulum angle of left and right wind direction change blade 14 depends on the anglec of rotation of the motor 38 held in vane drive mechanism 33.When along the side with the arrow B in Fig. 9 in the opposite direction actuating arm 36 time, left and right wind direction changes blade 14 and swings in the opposite direction along with the side shown in Figure 10 (a), and air is discharged left from air conditioner.
In the above-described embodiments, as illustrated best in Fig. 3, left and right wind direction changes blade assembly 13 and is made up of lobus lateralis dexter chip module 13R and lobus lateralis sinister chip module 13L, and wherein lobus lateralis dexter chip module 13R and lobus lateralis sinister chip module 13L has vane drive mechanism 33 separately and changes its angle independently.Therefore, by guiding lobus lateralis dexter chip module 13R to the right and guiding lobus lateralis sinister chip module 13L to produce wider air stream left, and by guiding them to produce air stream in centralized in opposite direction.But the connection cross bar 16 of lobus lateralis dexter chip module 13R and the connection cross bar 16 of lobus lateralis sinister chip module 13L can form as one or be interconnected.In this case, lobus lateralis dexter chip module 13R and lobus lateralis sinister chip module 13L is always directed in the same direction, therefore, no longer may produce the air stream in wider air stream or centralized, but the number of vane drive mechanism 33, connector 34 and connector 35 can be reduced to one (but needing two in the above-described embodiments) respectively, thus causes cost to reduce.
