The specific embodiment
As illustrated in fig. 1 and 2, air conditioner according to the present invention comprises main body 1, fan guard 2, stabilizer 3 and inspiratory gate 4, limits air flue 6 by all these parts in air conditioner.Room air sucks air conditioner by the fan 7 being arranged in air flue 6 by inspiratory gate 4.The heat exchanger 8 of the upstream of the air sucking like this by being arranged in fan 7 with respect to the direction of air stream 5 carries out heat exchange, and is discharged to indoor via flow direction changer 11 by outlet 10 by the air that heat exchanger 8 carried out heat exchange.Outlet 10 is formed by following part: the part in the downstream that is arranged in air flue 6 of fan guard 2; Waste water dish (waste pan) 9c, its top of downstream part that is formed on fan guard 2 is to be received in the waste water that cooling period is produced by heat exchanger 8; Stabilizer 3, its upstream side that is formed on waste water dish 9c is with stable air stream 5; And there are the exhaust grid 9 of relative sidewall 9b.
Flow direction changer 11 comprises: change blade assembly 12 for the wind direction up and down that changes wind direction at above-below direction, change blade assembly 13 for the left and right wind direction that changes wind direction at left and right directions, change vane drive mechanism (not shown) for the wind direction up and down that drives upper and lower wind direction to change blade assembly 12, and change vane drive mechanism 33 (this mechanism is hereinafter referred to as " vane drive mechanism ") for the left and right wind direction that drives left and right wind direction to change blade assembly 13 as shown in Figure 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.
As shown in Fig. 3,4,5A and 5B, lobus lateralis dexter chip module 13R and lobus lateralis sinister chip module 13L comprise multiple blades 14 separately, for the support rail 15 of support blade 14 swingably, and extend abreast to operate blade 14 with support rail 15 simultaneously be connected cross bar 16.Each blade 14 has and is formed on its front side with the upwardly extending fixed axis 18 in edge from it, and forms in the central part with the upwardly extending horizontal movable axis 20 in edge from it.Fixed axis 18 inserts in the opening 17 of the roughly keyhole shape defined in support rail 15 loosely, and horizontal movable axis 20 inserts in the opening 19 connecting defined in cross bar 16 loosely.
As illustrated best in Figure 10 (b), roughly the opening 17 of keyhole shape is such opening: it has major diameter round hole (right side of Figure 10 (b)), minor diameter circular hole (left side of Figure 10 (b)) and the otch for two circular holes are communicated with each other.Major diameter round hole only uses in the time that each blade 14 is combined as a whole with support rail 15.That is, first fixed axis 18 inserts in major diameter round hole, is then shifted towards minor diameter circular hole by otch.Although the width of otch is less than the diameter of fixed axis 18, fixed axis 18 can pass otch, because each side of otch has elasticity.Therefore,, once fixed axis 18 arrives minor diameter circular hole, fixed axis 18 just remains in minor diameter circular hole.
As shown in Fig. 4 (a), support rail 15 has evagination axle 31, and its contrary side at guide plate 22 is fastened to support rail 15.Evagination axle 31 is concentric and have a circular cross-section with cross bar rotating shaft 21.Evagination axle 31 is also formed with cross bar rotating shaft 21 at its far-end, and it is connected to the support arm 25a of (the following describes) upper and lower wind direction change blade 24.
As shown in Figure 5A, upper and lower wind direction changes blade assembly 12 and comprises: the blade 24 of horizontal extension, its general planar but slight curvature in the direction of extending at relative minor face; And multiple spaced support arm 25a, 25b, 25c, 25d, 25e, they are formed on the concave surface of blade 24 to be connected with the cross bar rotating shaft 21 of support rail 15. Support arm 25a, 25b, 25c, 25d, 25e have the supported hole 26 of opening forwardly separately so that one of support rail rotating shaft 21 rotatably.Upper and lower wind direction changes blade 24 and also has two additional support arm 25f on the concave surface that is formed on its relative side.Each support arm 25f has evagination rotating shaft 27, and another rotating shaft 27 is formed between central two support arm 25d, the 25e of upper and lower wind direction change blade 24.These rotating shafts 27 serve as the pivot of upper and lower wind direction change blade 24 during upper and lower wind direction changes blade 24 rotations, therefore, the longitudinal center line of each rotating shaft 27 and the spaced apart certain distance of line that is connected the supported hole 26 center in support arm 25a, 25b, 25c, 25d, 25e.As illustrated best in Fig. 4 (a), the rotating shaft 27 of support arm 25f rotatably inserts in the axis hole 9a defined in each sidewall 9b of exhaust grid 9, and similarly, central rotating shaft 27 rotatably inserts being coupling defined in (explanation after a while) central support portion 28 and receives in opening 29.
As shown in Fig. 4 (a) and 5B, sliding axle 32 is arranged between the sidewall 9b of exhaust grid 9 and lobus lateralis sinister chip module 13L so that the rotating shaft 27 that can change blade assembly 12 with upper and lower wind direction slide axially in line.Sliding axle 32 is connected to the arm 36 of the vane drive mechanism 33 that is arranged in sidewall 9b outside via bolt 37.Vane drive mechanism 33 comprises motor 38, its operationally by arm 36 from a side drive to opposite side so that sliding axle 32 slide.
Sliding axle 32 is connected to the connector 34 as shown in Fig. 4 (b).Connector 34 with and the upper and lower wind direction equidistant interval of changing between supported hole 26 and the rotating shaft 27 of blade assembly 12 be limited with two hole 34a, 34b.Sliding axle 32 is rotatably received in the 34a of hole, and evagination axle 31 is rotatable and be received in slidably in the 34b of hole.Sliding axle 32 has the laterally projecting retainer 32a that is formed on its far-end.Retainer 32a has the less width of width of otch 34c limiting than hole 34a mono-side at connector 34, make after retainer 32a aligns with otch 34c, the far-end of sliding axle 32 can patchhole 34a in.Once by the far-end patchhole 34a of sliding axle 32, by sliding axle 32 is rotated to predetermined angular, retainer 32a just plays anti-skidding axle 32 effect that move in the left side (a) from hole 34a to Fig. 4.Sliding axle 32 is also formed with annular stop 32b, and it plays the effect that anti-skidding axle 32 slides with respect to connector 34 to the right.
Another connector 35 is arranged on the evagination axle 31 of support rail 15 and has two isolated near-ends and a forked far-end.Each near-end has the batter of being coupling 35b, and the evagination axle 31 of support rail 15 is received in loosely and is coupling in batter 35b, and far-end has otch 35a, is fastened to the lower projecting pin 16a that connects cross bar 16 and inserts loosely in otch 35a.A part (side of hole 34b) for connector 34 is clipped between two isolated near-ends of connector 35, to make two connectors 34,35 can synchronous slide.Even if vane drive mechanism 33 is fixed, vane drive mechanism 33 is connected to support rail 15 via two connectors 34,35 and also not only allows left and right wind direction change blade 14 to swing with this structure that is connected cross bar 16, and allows upper and lower wind direction to change blade assembly 12 and left and right wind direction change blade assembly 13 synchronous rotaries.
As shown in Fig. 3,4,5A and 5B, upper and lower wind direction changes blade assembly 12 and left and right wind direction change blade assembly 13 combines and is connected to central support portion 28, and this central support portion 28 is fixedly installed to exhaust grid 9 at the horizontal centre part place of outlet 10.
The assembling of flow direction changer 11 is discussed and how is packed into outlet 10 with reference to accompanying drawing hereinafter.
As shown in Figure 3, each component assembling that a pair of left and right wind direction is changed in blade assembly (lobus lateralis dexter chip module 13R and lobus lateralis sinister chip module 13L) is integrated, subsequently each rotating shaft 21 of support rail 15 is inserted in the corresponding supported hole 26 in support arm 25a, 25b that upper and lower wind direction changes blade assembly 12,25c, 25d, 25e, as shown in Figure 5 B, thus complete the assembling of changing blade assembly 12 and left and right wind direction and change the flow direction changer 11 that blade assembly 13 forms by upper and lower wind direction.
After this, flow direction changer 11 is inserted in the outlet 10 in air conditioner.Under this occasion, as Fig. 3,4 and 5B as shown in, be formed on rotating shaft 27 between central support arm 25d, the 25e that upper and lower wind direction changes blade assembly 12 and rotatably insert being coupling of support component 28 and receive in opening 29, and guide finger 23 inserts in the gathering sill 30 in support component 28 loosely.
In addition the rotating shaft 27 that, upper and lower wind direction changes the support arm 25f of blade assembly 12 rotatably inserts in the axis hole 9a defined in the side arm 9b of exhaust grid 9 with supporting rotating shaft 27 (only showing a side in Fig. 4).After flow direction changer 11 being fixed to exhaust grid 9, by vane drive mechanism 33 from external stability to sidewall 9b, and via bolt 37, the arm of vane drive mechanism 33 36 is connected to sliding axle 32.In the situation that not using bolt 37, can with engaging of hole etc., arm 36 and sliding axle 32 be connected to each other by hook.
In order to make flow direction changer 11 in above-below direction rotation, be connected to the rotating shaft such as the drive motors (not shown) of stepper motor etc. by being arranged on one of rotating shaft 27 that upper and lower wind direction changes the both sides of blade assembly 12.
The operation of the flow direction changer 11 of above-mentioned structure is discussed with reference to Fig. 6 A, 6B, 7A, 7B, 8A and 8B hereinafter.Fig. 6 A and 6B describe outlet 10 and have been changed by upper and lower wind direction the state of blade 14 closures.Fig. 7 A and 7B describe to guide upper and lower wind direction to change blade 14 about 45 degree downwards from horizontal plane, are located at thus the state in the centre position between complete release position and complete closing position.Fig. 8 A and 8B describe upper and lower wind direction and change the state of blade 14 approximate horizontal extensions with complete open row outlet 10.
In the time that air conditioner does not turn round, outlet 10 changes blade 14 closures by upper and lower wind direction, as shown in Figure 6 A and 6B.During cooling, preferably, upwards guide 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, in the time starting to heat, upper and lower wind direction is changed to blade 14 and remain on the complete release position scheduled time shown in Fig. 8 A and 8B, once and make to add thermally-stabilised, just upper and lower wind direction is changed to blade 14 and remain on the centre position shown in Fig. 7 A and 7B and discharge downwards to control the warm air of discharging from air conditioner.
In the time that upper and lower wind direction change blade assembly 12 rotates up the position of Fig. 8 A and 8B from the position of Fig. 7 A and 7B, the part of the bottom adjacent to outlet 10 of left and right wind direction change blade 14 and fan guard 2 is substantially parallelly along the direction shown in arrow A from upstream side lateral movement towards downstream.As a result, left and right wind direction change blade 14 is always positioned at the main flow part of the air that will discharge from outlet 10.The term " main flow part " adopting in whole the application is defined as such part of air stream 5: at this part place, left and right wind direction changes blade 14 makes the air that will discharge from outlet 10 in left and right directions bending the most efficiently., main flow part is arranged in the downstream of the air flue 6 of air conditioner.
The action of left and right wind direction change 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 with respect to the setting angle of support rail 15, and the shape of gathering sill 30.; in the time that 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 cross bar rotating shaft 21 left and right wind direction that is rotatably inserted into respective support hole 26 in support arm 25a, 25b, 25c, 25d, 25e changes blade assembly 13 and moves towards downstream with respect to the direction of air stream 5 in rotary bar rotating shaft 21.Because guide finger 23 is connected to one of cross bar rotating shaft 21 and inserts in the gathering sill 30 of central support portion 28 via guide plate 22, so the motion of rotation that guide finger 23 is followed cross bar rotating shaft 21 is by the shape control of gathering sill 30 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.
; left and right wind direction changes the motion path of blade assembly 13 by the shape control of gathering sill 30; therefore; can can, along the shape of moving towards downstream with the substantially parallel direction of the part of the bottom adjacent to outlet 10 of fan guard 2, make left and right wind direction change blade 14 and do such motion by gathering sill 30 being formed as make left and right wind direction to change blade 14.In the situation that there is no gathering sill 30, in the time that upper and lower wind direction changes blade assembly 12 and rotates to the state of Fig. 7 B from the state of Fig. 6 A, left and right wind direction changes blade 14 by the position shown in the double dot dash line moving in Fig. 7 A.
Illustrate that with reference to Fig. 4,9 and 10 left and right wind direction changes the angle change of blade 14 hereinafter.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 holding in vane drive mechanism 33 is in the direction of arrow B when actuating arm 36, the sliding axle 32 that is connected to arm 36 slides in the same direction together with connector 34, and wherein connector 34 is rotatably installed on sliding axle 32 but can not slides with respect 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, so connector 35 slides together with arm 36 with connector 34, sliding axle 32.
Because be fastened in the otch 35a in the pin 16a insertion connector 35 that connects cross bar 16, slide in the direction of arrow B together with connector 35 so connect cross bar 16.Figure 10 describes to connect the state that cross bar 16 has moved in the direction of arrow B.As shown in Fig. 4 (b), pin 16a has the annular stop 16b forming at its far-end and separates from pin 16a to prevent connector 35.
Connecting cross bar 16 makes the left and right wind direction change blade 14 that is rotatably connected to connection cross bar 16 via movable axis 20 rotate around each fixed axis 18 with respect to the slip of support rail 15.As shown in the double dot dash line in Figure 10, the pin 16a that connects 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 (referring to Fig. 4 (b)) in the direction vertical with the direction of arrow B.
Suppose that replacing the evagination axle 31 of support rail 15 to be rotatably received in two of connector 35 at the situation downslide moving axis 32 that connector 34 is not set is coupling in batter 35b, and the pin 16a that supposition connects cross bar 16 inserts in the otch 35a in connector 35.Because connect cross bar 16 along with upper and lower wind direction changes the rotation of blade assembly 12 and rotates, change as shown in Fig. 6 A and 7A so connect the position that cross bar 16 changes the rotating shaft 27 of blade assembly 12 with respect to sliding axle 32 or upper and lower wind direction, and the distance L 3 that the longitudinal center line of rotating shaft 27 and left and right wind direction change between the longitudinal center line of movable axis 20 of blade 14 also changes.Although can accommodate by the otch 35a in connecting piece for lengthening 3 change of distance L 3, but connect cross bar 16 and face the surface of connector 35 with respect to the very large change of angle generation of the evagination axle 31 of support rail 15, as shown in the C in Fig. 6 A or 7A, due to this reason, can not use the connector of the shape identical with the shape of connector 35.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 and connects cross bar 16 via connector 35.By doing like this, angle changes C and is accommodated by connector 34, and therefore, connecting cross bar 16, always to keep facing with connector 35 surface of connection cross bar 16 parallel.Therefore, during upper and lower wind direction changes blade 24 rotations, between connector 35 and connection cross bar 16, can not disturb, thereby allow to connect cross bar 16 Smooth Rotations and allow connection cross bar 16 smoothly to slide together with connector 35.
Above-mentioned structure allows in the time of air-conditioner operation, left and right wind direction change blade 14 is always positioned at the main flow part of air stream 5 and sentences the angle that just effectively changes left and right wind direction change blade 14, and no matter the position that upper and lower wind direction changes blade 24 how, thereby make 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 in the above-described embodiments because the large change of the angle C shown in the caused Fig. 6 A of high rotation angle degree or the 6B of upper and lower wind direction change blade 24 arranges connector 34, for example, if but the anglec of rotation that upper and lower wind direction changes blade 24 is less (, thereby needn't closed row outlet 10 permissions if upper and lower wind direction changes that blade 24 only swings between the state of Fig. 7 A or 7B and the state of Fig. 8 A or 8B being connected cross bar 16 and connector 35 leaves each other nargin and engages), also can save connector 34.
