Description
Technical field
The invention belongs to the technology of relevant integral air conditioner, particularly relate to a kind of motor shaft structure of fan for integral air conditioner that fan rotation vibration and noise are reduced.
Background technology
In general air-conditioner is arranged on vehicle, office, the space that family etc. are indoor or be arranged on the machine that on the wall indoor air is cooled off or heats mainly constitutes circulating system by compressor-outdoor heat converter-parts such as expansion valve-indoor heat converter.
Air-conditioner is divided into and mainly is arranged on outdoor outside (perhaps off-premises station) and is arranged on indoor indoor (perhaps indoor set), and the outside then is the heat release side when in refrigeration the time, and the indoor then is a heat absorbing side.Also have, outdoor heat converter and compressor are being set on the outside, the indoor then is being provided with indoor heat converter.
Air-conditioner can be divided into indoor and outside detachable air conditioner and the integral air conditioner that becomes one of outside and indoor apart, and that detachable air conditioner can be divided into according to the difference of installation form is wall-hanging, roof type, vertical etc.Integral air conditioner is that the center is divided into indoor formation indoor with the window, the outdoor air-conditioner that then is divided into window type air conditioner and is arranged on outer body of wall the inside.
Fig. 1 is the primary structure exploded view of the integral air conditioner of conventional art making, internal structure with reference to 1 pair of integral air conditioner of figure describes, the following chassis 1 that forming of air-conditioner at first, the front of the indoor on chassis 1 is being provided with front panel 3, front panel 3 forms the outward appearance in the front of air-conditioner, and it is arranged on the front of cabinet 30.
The 3i of suction portion that air is incorporated into the air-conditioner inner space is being set on front panel 3 one sides, opposite side is being provided with the air of finishing heat exchange in air-conditioner inside and is being discharged into indoor exhaust portion 3e, on the 3i of suction portion intake panel 4 is being set, the following control part 3c that controls the air-conditioner running that is being provided with of exhaust portion 3e.
The inboard of front panel 3 is being provided with indoor heat converter 7.Indoor heat converter 7 is that air and the refrigerant that the 3i of suction portion by panel 3 enters carries out heat exchange, is fixedly installed on more precisely on the following air guiding device that will illustrate 9.
The rear of indoor heat converter 7 is being provided with air guiding device 9, on air guiding device 9, forming the through hole 10 that the air by indoor heat converter 7 passes through, the exhaust portion 3e of front panel 3 is forming air discharge guide device 9e on the mutual corresponding position, is forming the discharge structure 9 ' of the condensed water that produces on indoor heat converter 7 in the bottom surface of air guiding device 9.
Dividing plate 11 with air guiding device 9 combinations is being set at the rear of air guiding device 9, on the inner face of dividing plate 11, is forming air guide of flow face 12, the following centrifugal fan that will illustrate 19 caused air are being carried out the guiding of air-flow.
With the control box 14 that the various electronic units that the control air-conditioner is installed are being set above the chassis 1 of the control part 3c correspondence position of front panel 3.2 screws of control box 14 front ends are being connected with chassis 1, and rear end and air guiding device 9 link together by screw and be fixed.
In the back of dividing plate 11 baffle plate 15 of dividing air conditioner chamber inboard and outside is being set, baffle plate 15 is divided the indoor of air-conditioner and outside, thereby the environment that has prevented indoor environment and outside is affected mutually.The back of baffle plate 15, be have on the outside motor cabinet 18 be arranged on chassis 1 above, fan electromotor 17 here is being set, the fan electromotor axle 17A of fan electromotor 17 forms to indoor and outside are outstanding separately, the fan electromotor axle 17A of one side is connecting baffle plate 15 giving prominence to dividing plate 11 inside of indoor, on the outstanding fan electromotor axle 17A in indoor centrifugal fan 19 is being set, centrifugal fan 19 is indoor air to be incorporated into carry out heat exchange on the indoor heat converter 7 and be sent to air indoor by air discharge guide device 9e more afterwards.
On the outdoor side shaft of fan electromotor 17 aerofoil fan 21 is being set, aerofoil fan 21 is introduced the air of outside, and air is carried out heat exchange by outdoor heat converter 27.
Have cabinet 30 above the chassis 1 and cover the various parts that are arranged on the inside, cabinet 30 and chassis 1 link together, and are covering two sides and the top of air-conditioner.
At this,, parts such as compressor and expansion valve are being set also on the outside though do not illustrate.
The indoor of integral air conditioner is arranged in the space that air need upgrade, and the outside then is arranged on outdoor.When air-conditioner when cooling off, air-conditioner comes into operation, the air-conditioner inner loop also brings into operation, fan electromotor 17 is rotated centrifugal fan 19 and aerofoil fan 21.
At this moment, the air of indoor is sent on the indoor heat converter 7 by the 3i of suction portion of panel 3, air in by indoor heat converter 7 and refrigerant carry out heat exchange and become the relatively air of low temperature.
The air that finishes heat exchange along with the rotation of centrifugal fan 19 will be drawn into centrifugal fan and go for 19 li by the through hole 10 of air guiding device 9, and then air is discharged by centrifugal fan 19, inside along dividing plate 11 is sent on the air discharge guide device 9e, and the air that is sent to air discharge guide device 9e then enters into indoor by the exhaust portion 3e on the front panel 3.
The refrigerant that operates on the outside obtains heat to outdoor discharging from indoor heat converter 7, be air outside because of aerofoil fan 21 enters into the outside of air-conditioner, be directed frame 23 guiding and carry out heat exchange by outdoor heat converter 27 and refrigerant heat is emitted to the outside.
With reference to figure 2-Fig. 4, be fixed with fan electromotor axle 17A on the rotor of fan electromotor 17 and connect motor, fan electromotor axle 17A two ends form the certain-length plane in same direction, and an end inserts in the wheel hub groove of centrifugal fan 19, and the other end inserts in the wheel hub groove of aerofoil fan 21.The fan at two ends is fixed or adopted other method to fix by locknut.
But, as air-conditioner in the past following problem points is arranged:
Summary of the invention
