Embodiment
Below by drawings and examples, technical scheme is described in further detail.
As shown in figure 1, the structural representation of the embodiment for air-conditioning internal machine of the present invention.In the present embodiment, in air-conditioning
Machine includes：Internal air channel 11 and counter-rotating fan 2.Internal air channel 11 connects with the air inlet 12 and exhaust outlet 13 of air-conditioning internal machine, right
Cyclone cluster 2 is arranged in internal air channel 11, for guiding air-flow to flow to exhaust outlet 13 from air inlet 12 along internal air channel 11.
Internal air channel 11 can be formed inside the body 1 of air-conditioning internal machine, and air inlet 12 and exhaust outlet 13 may be referred to
The both ends in internal air channel 11 are separately positioned on shown in Fig. 1.In another embodiment, the setting position of air inlet 12 and exhaust outlet 13
The other positions that end is removed in internal air channel 11 can also be arranged on by putting.Internal air channel 11 may be referred to shown in Fig. 1 vertically
Set, and air inlet 12 is arranged on to the lower position of body 1, exhaust outlet 13 is arranged on to the upper position of body 1.At other
In embodiment, the inside air channel of horizontal direction or incline direction can also be used, air inlet and gas outlet can also be relative to machines
Body 1 is arranged in other positions.
Counter-rotating fan 2 is optional including the first axial flow blower 21 and the second axial flow blower 22, the first axial flow blower 21 and second
22 axially adjacent arrangement of axial flow blower, and the first axial flow blower 21 and the second axial flow blower 22 is oppositely oriented.That is,
If the first axial flow blower 21 turns clockwise, the rotate counterclockwise of the second axial flow blower 22；It can also be the first axial flow blower
21 rotate counterclockwises, then the second axial flow blower 22 turn clockwise.Can internally be arranged in air channel 11 more than one group to rotation
Blower fan 2, oppositely oriented two axial flow blowers can provide and solve the single less problem of axial flow blower static pressure, and compared to
It is limited less centrifugal blower on installation direction and position, freer in design.
With reference to figure 1 and Fig. 2, the first axial flow blower 21 can include axial-flow leaf 211 and motor 212, the second axle stream motor
22 can include axial-flow leaf 221 and motor 222.Motor 212 and 222 is separate, and spatially adjacent, the He of motor 212
222 motor output shaft can stretch out to the opposite direction of same axis.Axial-flow leaf 211 and 221 may be mounted at motor output
On axle, it can also be installed on motor housing.
In one embodiment, with reference to figure 3, the axial-flow leaf 2a in the first axial flow blower 21 and the second axial flow blower 22 is equal
Using external rotor electric machine provide driving force, that is to say, that motor 212 and 222 is external rotor electric machine, the shell of this motor with
Axial-flow leaf 2a inner ring 2b fixed settings, the output shaft of external rotor electric machine are fixed relative to internal air channel 11.Another
Any one in individual embodiment or in the first axial flow blower 21 and the second axial flow blower 22 uses external rotor electric machine, separately
One uses inner rotor motor.
In order to facilitate the fixation of the output shaft of external rotor electric machine, internally can set in air channel 11 and the internal phase of air channel 11
To fixed support, output shaft and the support of external rotor electric machine are fixed.Such as internally air channel 11 sets cross branch
Frame, the center of support and the output shaft of external rotor electric machine are fixed.This external rotor electric machine is because output shaft is fixed, axial-flow leaf 2a
Inner ring 2b and the shell of external rotor electric machine fix, therefore the jib-length of corresponding axial flow blower is 1/2 outer cover length+output
Shaft length, it is shorter than the jib-length (being equal to outer cover length+output shaft length) of inner rotor motor, therefore bending load is more
It is low.
With reference to figure 2, the quantity of the axial blade of the axial blade of the first axial flow blower 21 and the second axial flow blower 22 is preferred
Prime number each other, the covibration that may occur when being run with eliminating.For example, axial-flow leaf 211 includes 6 fan blades, axial-flow leaf
221 include 7 fan blades.In addition, the first axial flow blower 21 and the second axial flow blower 22 can exchange relative to air motion direction
Position, blade angle and rotation direction can be adjusted accordingly as the case may be.
If by the above-mentioned air-conditioning internal machine embodiment using counter-rotating fan 2 of the invention and the air-conditioning using single axial flow blower
Interior machine is in same design air quantity (such as 1200m3/ h) and rotating speed (N=960rad/min) under be compared, in air-conditioning of the present invention
Machine embodiment will be reduced by about 20% on the outside dimension of counter-rotating fan compared to the outside dimension of single axial flow blower, in static pressure
It is upper to increase by 18%, increase by 10% in efficiency.
In order to further reduce the installing space of air-conditioning internal machine, with reference to figure 1, air-conditioning internal machine embodiment of the invention can be with
Further comprise the heat exchanger 3 for being arranged on V-shaped layout in internal air channel 11.The heat exchanger of this V-type layout is compared to existing
The heat exchanger of yi word pattern layout adds heat exchange area by about one time, and simultaneously unobvious increase on the arrangement space in body 1.
In Fig. 1, heat exchanger 3 is optional is arranged in internal air channel 11 relative to 12 inner side of air inlet, to enter
Gas position is just more fully exchanged heat, and the temperature difference between exhaust outlet air-flow and the external world can be reduced compared to other positions,
To reduce or eliminate the dew condensation phenomenon of exhaust outlet.Specifically, heat exchanger 3 is preferably located to the lower section of counter-rotating fan 2.In addition,
Drip tray 4 can also be set below heat exchanger 3, so as to which the water droplet to conflux can be accepted in condensation on heat exchanger 3, avoid dirt
Dye or corrosion body 1.
Above-mentioned each air-conditioning internal machine is applicable to all kinds of apparatuses of air conditioning, is particularly suitable for application to air conditioner.Therefore, this hair
It is bright to additionally provide a kind of air conditioner, including foregoing air-conditioning internal machine, it can reach and reduce the technique effect that installing space takes.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
The embodiment of the present invention can be modified or equivalent substitution is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical scheme, it all should cover among the claimed technical scheme scope of the present invention.
