For solving the problems of the technologies described above, the technical solution of the utility model is: the air-supply arrangement that a kind of air conditioner room unit is provided, comprise the wind wheel of hollow and the drive motors of fixing with described wind wheel, described drive motors is an external rotor electric machine, the outer rotor of described external rotor electric machine stretches in the hollow hole of described wind wheel, and described outer rotor is fixedly connected with described wind wheel.
Particularly, described outer rotor is provided with clamping ring, and described clamping ring and described wind wheel end face are locked by securing member.
Further, described clamping ring end face is provided with locating hole, and described wind wheel end face is provided with the locating dowel that penetrates in the described locating hole.
Perhaps, described outer rotor is provided with rubber ring, and described rubber ring is provided with joint pin, and described wind wheel end face is provided with for described joint pin and penetrates fixing connecting hole.
Perhaps, be embedded on the described wind wheel end face and fix a retainer ring, described retainer ring and described outer rotor interference fit.
The utility model, adopt external rotor electric machine as drive motors, and outer rotor extend into wind wheel inside, saved a large amount of installing spaces, dispel the heat for during simultaneously blower fan rotation the motor surface, the temperature rise that reduces that the motor feels hot, improve electric efficiency, and external rotor electric machine itself has magnetic property and the rotary inertia that is superior to inner rotor motor, be more suitable for being used in the driving of wind wheel, when identical output torque request, external rotor electric machine volume ratio inner rotor motor can be done littlely, efficient is higher, adopts the indoor apparatus of air conditioner of this air-supply arrangement also can do less more attractive in appearancely.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model provides a kind of air-supply arrangement of air conditioner room unit, comprise the wind wheel of hollow and the drive motors of fixing with described wind wheel, described drive motors is an external rotor electric machine, the outer rotor of described external rotor electric machine stretches in the hollow hole of described wind wheel, and described outer rotor is fixedly connected with described wind wheel.The utility model, adopt external rotor electric machine as drive motors, and outer rotor extend into wind wheel inside, saved a large amount of installing spaces, dispel the heat for during simultaneously blower fan rotation the motor surface, the temperature rise that reduces that the motor feels hot, improve electric efficiency, and external rotor electric machine itself has magnetic property and the rotary inertia that is superior to inner rotor motor, be more suitable for being used in the driving of wind wheel, when identical output torque request, external rotor electric machine volume ratio inner rotor motor can be done littlely, efficient is higher, adopts the indoor apparatus of air conditioner of this air-supply arrangement also can do less more attractive in appearancely.
The external rotor electric machine that adopts in the utility model and the fixed form of wind wheel can have multiple, enumerate three embodiment below in conjunction with accompanying drawing and describe in detail.
Embodiment one
With reference to Fig. 1, Fig. 2, the air-supply arrangement of the air conditioner room unit that present embodiment provides comprises the wind wheel 100 of hollow and the drive motors of fixing with wind wheel 100, and drive motors is an external rotor electric machine 200.External rotor electric machine 200 comprises motor shaft 210, bearing 220, motor stator 230, outer rotor 240 and end cap 250, and its structure is identical with external rotor electric machine 200 in the prior art, does not carefully state herein.In the present embodiment, the outer rotor 240 of external rotor electric machine 200 stretches in the hollow hole (among the figure not label) of wind wheel 100, and outer rotor 240 is fixedly connected with wind wheel 100.
