Wall;The air inlet of wind guide component 136 connects with the exhaust outlet of spiral case 134.
Fig. 6 is the signal of air-supply assembly in the wall-hanging indoor unit of air conditioner 100 according to the utility model one embodiment
Figure.Air-supply assembly includes:Centrifugal blower 131 and wind guide component 136.Due to ensureing the air jet velocities of air ejection member 120,
The air-supply assembly of the present embodiment uses power source of the centrifugal blower 131 as air-flow.
Centrifugal blower 131 is converted to the principle of potential energy according to kinetic energy, is accelerated gas using high-speed rotating impeller 133,
Then slow down, change flow direction, kinetic energy is made to be converted into potential energy.It generally comprises collection gas port 132, impeller 133, spiral case 134.Centrifuge wind
Machine 131 integrates gas port 132 as the air inlet of wind turbine 131, and it acts as ensure that air-flow can equably import circle full of impeller 133
Face reduces flow losses, and in the present embodiment, the direction of collection gas port 132 to the impeller 133 of centrifugal blower 131 is tapered, forms loudspeaker
Mouth, the air intake impeller 133 that will can be exchanged heat as possible with heat exchanger 140 in heat exchanger accommodating chamber.The leaf of centrifugal blower 131
When wheel 133 is rotated with the axis by the drive of high-speed electric expreess locomotive 135, the gas between impeller 133 rotates with impeller 133 and obtains centrifugal force, gas
Body is thrown out of impeller 133, and into spiral case 134, the gas pressure intensity in spiral case 134, which increases, is directed to discharge.Interlobate gas quilt
After discharge, negative pressure is formed;140 air of heat exchanger in heat exchanger accommodating chamber outside collection gas port 132 is constantly inhaled into, to shape
At continuous flow.
The impeller 133 of centrifugal blower 131 is set to spiral case 134 in the space that partition board 143 is limited with case 112, and
Side wall of the exhaust outlet of spiral case 134 towards shell 110;The air inlet of wind guide component 136 connects with the exhaust outlet of spiral case 134.Snail
Shell 134 is helical, inhales the air that collection is thrown away from impeller 133, and by gradually wealthy sectional area, the dynamic pressure of air-flow is turned
Turn to static pressure.
Wind guide component 136 is connected between the exhaust outlet of centrifugal blower 131 and the air feed chamber 125 of air ejection member 120, and
Air-flow for centrifugal blower 131 to be discharged leads into air feed chamber 125.Wind guide component 136 may include Drainage Section 137 and supply
Wind section 138.
Drainage Section 137 has the air inlet of wind guide component 136, and at least partly segment body of Drainage Section 137 is spiral,
It is downward by the guiding of airflow direction that centrifugal blower 131 is discharged, Drainage Section 137 is from the air inlet of wind guide component 136 along air-flow side
To tapered, to accelerate the wind speed that air-flow enters the air collecting chamber 139 of air feed section 138.
Air feed section 138 connects with Drainage Section 137, inside limit air collecting chamber 139, with receive centrifugal blower 131 be discharged
Air-flow, air feed section 138 is provided with the exhaust outlet towards air ejection member 120, so that the air-flow of air collecting chamber 139 feeds to air feed chamber 125.
Air-out direction of the air feed section 138 along Drainage Section 137 forms scroll casing shape, reduces windage of the air-flow in air collecting chamber 139, it is made to collect
It is formed and is vortexed in air cavity 139, successfully can lead to air feed chamber 125 from air collecting chamber 139.
Above-mentioned Drainage Section 137 can be arranged in the side of centrifugal blower 131, since the space of partition board 143 limits, Drainage Section
137 longitudinal separation is smaller, and air feed section 138 is located at lower section (namely partition board 143 and the heat exchanger 140 of heat exchanger accommodating chamber
Lower section), therefore its distance in the front-back direction is more than Drainage Section 137, the exhaust outlet of air feed section 138 is set to air collecting chamber 139 and reclines
Front in 120 side of air ejection member.The air inlet of air ejection member 120, which is arranged in two sections of curved sections 129, is located at air dam
On the annular outer wall 122 of the curved section 129 of 136 side of part.
