Left fan 210 ' form and right side fan 210 " identical, and fan is set to towards each other.Its specific descriptions will not provide.
Figure 12 is arranged on the exterior perspective view according to the motor in the air blast of the present invention, and Figure 13 is the cutaway view of the motor got along line I-I '.
With reference to Figure 12 and 13, motor 220 comprises: stator 222, and it has the coil (C) that repeatedly twines; Fixed component 223, it is fixed to stator 222; Motor shaft 224, it is fastened to fixed component 223; And rotor 226, form described rotor and make its outside that surrounds stator 222 and its be provided with a plurality of permanent magnets (M).
Stator 222, fixed component 223 and motor shaft 224 interfix and remain on the fixed position, and rotor 226 is around motor shaft 224 rotations.Therefore, bearing (B) is arranged between rotor 226 and the motor shaft 224.
Stator 222 forms cylindrical shape and has a plurality of bobbin 222a that arrange at interval and radially form with rule, the outer felt of coil (C) roll around.Therefore, when from external power source when coil (C) is powered, produce predetermined electromagnetic field around the bobbin 222a.
The outside of the permanent magnet of rotor 226 (M) roll 222a is provided with to have closely spaced mode therebetween.That is, rotor 226 is installed and is comprised a plurality of permanent magnets that separate at interval with rule that are attached to rotor 226 inner surfaces around the periphery of stator 222.A plurality of permanent magnets (M) are quantitatively corresponding to bobbin 222a.
In this structure, when electric current during through the coil (C) of stator 222, the electromagnetic force that produces by coil (C) with by permanent magnet (M) thereby the magnetic force that produces interacts rotor 226.
As shown in the figure, motor shaft 224 extends with the right side to the left, and is formed by two axles.That is, thus left-hand axis and right-hand axis coupling connection forms motor shaft 224.Yet the single motor axle can insert motor in order to form the left side and the right side of motor shaft.Fixed component 223 is fixed to the core of motor shaft 224, make the end of motor shaft 224 be fixed to respectively Support bracket 240 and 240 '.
Fixed component 223 joins so that fixing and support stator 222 with motor shaft 224 couplings.That is, fixed component 223 forms round-shaped, and motor shaft 224 is installed on the core of fixed component regularly, and stator 222 is around the cylindrical setting of fixed component.
Figure 14 illustrates the exploded perspective view that is used for according to the coupling linked method of the Support bracket of air blast of the present invention and reinforcement.
With reference to Figure 14, Support bracket 240 and 240 ' comprising: core 242, this core 242 is passed in each end of motor shaft 224; And a plurality of support sections 244, it divides 242 to extend outwardly diametrically from central division.
And, shaft through-hole 246 also can comprise standing part 246 '.That is, shaft through-hole 246 forms with the shape of motor shaft 224 corresponding round-shaped; Yet the part circumferential of shaft through-hole 246 becomes straight line, then formation standing part 246 '.Standing part 246 ' form make its fixed surface that contacts above-mentioned motor shaft 224 224 '.Therefore, motor shaft 224 because standing part 246 and fixed surface 224 ' mutual maintenance and do not rotate.
A pair of rib fastener hole 248 is formed in the core 242.Rib fastener hole 248 be reinforcement 250 as described below and 250 ' fastening rib 254 insert wherein part.
Below, will the application of the outdoor unit of the air-conditioning of above-mentioned embodiment according to the present invention be described.
At first, when air-conditioning is operated (refrigeration mode), refrigerant flows between outdoor unit 100 and indoor unit (not shown).To refrigerant flowing in outdoor unit 100 be described herein.
The refrigerant that is in gaseous state flows into the liquid-gas separator 182 from the indoor unit (not shown).The gaseous refrigerant that leaves liquid-gas separator 182 flow into compressor 180 and 180 ' in.Employed compressor 180 and 180 ', as mentioned above, only comprise frequency-changeable compressor 180 according to load operation ', or comprise constant speed compressor 180 and frequency-changeable compressor 180 '.
From the refrigerant of compressor 180 and 180 ' discharge flow into heat exchanger 120 and 120 '.Heat exchanger 120 and 120 ' in refrigeration mode, use, in order to heat-shift between refrigerant and outdoor air, thus cooling liquid refrigerant.
Through compressor 120 and 120 ' the liquid reservoir 184 of refrigerant through overregulating refrigerant flow, flow into then in the indoor unit (not shown).Although not shown, the refrigerant that enters indoor unit heat-shift and be back to outdoor unit 100 in as the indoor heat converter of evaporimeter from indoor heat converter.Like this, in these steps, finish kind of refrigeration cycle.
Below, with describe air blast 200 and 200 ' operation.
When from external power source when stator 222 applies electric power, the electric current of the coil (C) that is twined by the roll 222a that flows through generates an electromagnetic field.Therefore, the electromagnetic force around the bobbin 222a interacts rotor 226 with the magnetic field that is produced by permanent magnet (M).Herein, the blower fan 210 that is installed on rotor 226 flange portions 228 rotates to produce air-flow with rotor 226.
When blower fan 210 rotations, air is inhaled in the outdoor unit 100 by the both sides of outdoor unit.That is, from the air of outdoor unit 100 outsides by left side air-inlet grille 130 and right side air-inlet grille 130 ' enter outdoor unit 100.
By left side air-inlet grille 130 and right side air-inlet grille 130 ' enter left side and the right side of the air of outdoor unit 100 inside by blower casing 230---perhaps more specifically by aperture, left side 234a and aperture, right side 234---to enter in the blower casing 230 towards blower fan 210 inside.
Thereby the air that enters blower fan 210 inside is in exhaust outlet 232 discharges that blowed in the radial direction by the front portion that is positioned at blower-casting 230 powerfully.The air of discharging by exhaust outlet 232 passes exhaust, safety grid 142 and discharges from the front portion of outdoor unit 100.
For with air blast 200 and 200 ' be installed on the support frame 144, air blast 200 and 200 ' air blast fixture 201 insert at the top of the fan mounting groove 144 of support frame 144 with towards lower slider.When the dismounting air blast, carry out the process opposite with installation process.That is, when upwards mentioning air blast 200 and 200 ' time, air blast fixture 201 along air blast holddown groove 144 ' slides within, thereby take off on the direction up air blast 200 and 200 '.
And, for dividing plate 160 is installed, the top that dividing plate 160 is inserted the septalium 158 of shells 150.So slide in two ends of dividing plate 160, thereby dividing plate 160 is installed on direction down in the septalium 158 of shell 150.In addition,, carry out opposite process, that is, upwards mention dividing plate 160 in order to take off dividing plate 160.Herein, thus two ends of dividing plate 160 along septalium 158 ' the direction of slides within up on remove dividing plate 160.
It will be understood by those of skill in the art that can be to making multiple remodeling and variation among the present invention.Therefore, the present invention has covered the remodeling and the variation of this invention, as long as it falls within the scope of claims and equivalent thereof.
