Among the above-mentioned figure, 10 be shell; 11 is suction inlet; 13 is outlet; 20 is the front housing department; 22 is stabilizer; 30 is back case portion; 32,33 for preventing to mix guide portion; 40 is cross flow fan; 50 is the front spacer; 60 is the back spacer.
The specific embodiment
To most preferred embodiment provided by the present invention, described in detail below with reference to accompanying drawing.
Fig. 1 is the oblique view by air discharging apparatus for air conditioning unit provided by the present invention, and Fig. 2 is by air discharging apparatus for air conditioning unit normal cross sectional drawing provided by the present invention, and Fig. 3 is by air discharging apparatus for air conditioning unit cross-sectional side view provided by the present invention.
The air discharging apparatus for air conditioning unit that the embodiment of the invention provided (being designated hereinafter simply as air exhausting device) has, by front housing department 20 and back case portion 30 in conjunction with the shell 10 that forms; Be arranged at the cross flow fan 40 of shell 10 inside; Be arranged at shell 10 inside, be used to the front- back spacer 50,60 that guides air to flow; By preventing to mix the guidance unit that guide portion 32,33 forms.
And, at suction inlet with sliding type in conjunction with a pair of filter 15, be used for filtering the air dust that flows into shell 10 inside.
As mentioned above, air exhausting device structure according to the present invention is horizontally set cross flow fan 40 in the shell 10 that horizontal expansion forms; Suction inlet 11 is arranged at the bottom of shell 10; A pair of outlet 13 is arranged at the two sides on shell 10 tops.By the bottom inhaled air of cross flow fan, be discharged to shell 10 two sides by guiding stream 14 from shell 10.
Thus, according to air exhausting device of the present invention, has the flow passage structure that the flow air that will make progress is guided two sides into, air might produce eddy current or stagnation behavior from the process that cross flow fan 40 is discharged, so, front and back spacer 50,60 is set in shell 10 inside reaches, be used to prevent to produce eddy current or stagnation behavior, make air flow to each outlet 13 smoothly by preventing to mix the guidance unit that guide portion 32,33 forms.
That is, at guiding stream 14 front spacers of being given prominence to by front housing department 20 50 and the back spacer of being given prominence to by back case 30 60 are set, the air from cross flow fan 40 is discharged is diverted to the outlet 13 that is formed at shell 10 two sides.Front spacer 50 and back spacer 60 are divided into the left and right sides with the guiding stream 14 of being located at cross flow fan 40 tops, and the air that cross flow fan 40 is discharged is diverted to each outlet 13.
In order successfully to be diverted to each outlet 13 from the air that cross flow fan 40 passes through, become 130～140 angle θ 3 that spend between the pair of angled face 62 in the angle θ 2, back case portion 30 that become 80～90 degree between the pair of angled face 62 in the angle θ 1, back spacer 60 that preferably become 120～140 degree between the pair of angled face 52 of front spacer 50 and cross flow fan 40 adjacent parts and the top contact portion, form two-layer inclined plane.
For the air that cross flow fan 40 transverse extension directions are discharged does not mix mutually and flows from top guiding stream 14, the bottom of back spacer 60 forms discharge portion (top of cross flow fan) to cross flow fan 40 and prolongs outstanding a plurality of guide portion 32,33 that prevents to mix.This prevents to mix guide portion 32,33, and to prolong cross flow fan 40 circumferencial directions outstanding, and housing department 30 forms inclined planes 34 in the back.
In addition, a plurality ofly prevent to mix among the guide portion 32,33, be positioned at drive motors 43 nearest sides prevent that mixing guide portion 32 is extended, make it prevent to mix the discharge portion that guide portion 33 more approaches cross flow fan 40 than other; From the air that drive motors 43 nearest winged petiole portions 42 discharge, the air of discharging than other winged petiole portions 42 flow to guiding stream 14 with the state that seldom spreads.
The air capacity that consideration is discharged near side drive motors 43 reduces than other sides, big air interference phenomenon takes place, and will be between the support plate 41 that is made as from the support plate 41a of the nearside of drive motors 43 and the interval L1 between the cross flow fan 40 in other parts half of L2 at interval, thereby suppress to greatest extent because air disturbs the noise that takes place.
Have again, between the bottom of front spacer 50 and the cross flow fan 40, be obliquely installed stabilizer 22 along cross flow fan 40 axially-extendings, to be used to isolate the discharge portion and the suction portion of cross flow fan 40.
Because cross flow fan 40 is separated into air suction portion and discharge portion by stabilizer 22, the air of discharging from cross flow fan 40 no longer sucks cross flow fan 40, so, can stable air flow.
Inclination is unfolded with 5～10 degree angle θ 4 in described stabilizer 22 and this stabilizer 22 relative back case portion 30 inclined planes, makes the air of discharging from cross flow fan 40, successfully flow to guiding stream 14.
The air exhausting device of the present invention of structure as mentioned above, cross flow fan 40 work, air flows into the inside of shells 10 by the suction inlet 11 of being located at shell 10 bottoms, by being arranged at each winged petiole portion 42, the 42a between cross flow fan 40 each support plate 41, the 41a.Air by each winged petiole portion 42,42a, up guided preventing to mix between the guide portion 32,33, flow to guiding stream 14 with immiscible state, be diverted to each outlet 13 that is arranged at shell 10 two sides, be discharged to shell 10 outsides by front spacer 50 and back spacer 60.
Thus, by shell 10 bottom leaked-in airs, be directed effectively to and prevent to mix guide portion 32,33 and front- back spacer 50,60, the axial flow of prolonging cross flow fan 40 is to increase exhaust air rate, to reduce the two sides discharge of the state of the noise that flows by shell 10.
Have again, a kind of air conditioner (not diagrammatic sketch) has the front, bottom and is provided with the casing that air inflow aperture, two sides, top are provided with air outflow port, the casing inside of this air conditioner is provided with air exhausting device, air then through air conditioner air inflow aperture and air exhausting device suction inlet 11 and by cross flow fan 40, after each outlet 13 was discharged, the air outflow port through being arranged at the air conditioner two sides was discharged again to the axial flow of cross flow fan 40.
