From.Centrifugal blower 151 can be from side to sucking surrounding air, from the jet of the air ejection member 120 of the lower section of the first air outlet 133
Mouth 124 sprays.Power source of the centrifugal blower 151 as mixed general mood stream, ensure that the air jet velocities of air ejection member 120.
Centrifugal blower 151 is driven by motor 155, and the principle of potential energy is converted to according to kinetic energy, utilizes high-speed rotating impeller
156 accelerate gas, then slow down, change flow direction, kinetic energy is made to be converted into potential energy.The collection gas port direction second of centrifugal blower 151
Air inlet 132 ensures that air-flow can equably be full of the import interface of impeller 156, reduces flow losses.The leaf of centrifugal blower 151
When wheel 156 is rotated with the axis by the drive of high-speed electric expreess locomotive 155, the gas between impeller 156 rotates with impeller 156 and obtains centrifugal force, gas
Body is thrown out of impeller 156, into spiral case 157.Gas pressure intensity in spiral case 157, which increases, is directed to discharge.Interlobate gas quilt
After discharge, negative pressure is formed.Air outside second air inlet 132 is constantly inhaled into, to form continuous flow.Spiral case 157 at
Spiral shape is inhaled the air that collection is thrown away from impeller 156, and by gradually wealthy sectional area, is converted the dynamic pressure of air-flow to quiet
Pressure.
Shell can also include mixed fan housing 113, and mixed fan housing 113 removably covers the outside for being buckled in air mixing device 150, thereon
Form the second air inlet 132.Mixed fan housing 113 is set to the side of the main part of shell, is consolidated by removably mode
It is fixed, to facilitate user to clean air mixing device 150.
Centrifugal blower 151 is set in mixed fan housing 113, and collection gas port direction mixes the end wall of fan housing 113, the row of spiral case 157
Gas port is downward.
Fig. 4 is the air supply direction schematic diagram of wall-hanging indoor unit of air conditioner 100 according to an embodiment of the invention.Mixed wind
Device 150 forms the mixed wind air duct independently of heat exchanging air duct with air ejection member 120, surrounding air is sucked, by the way of injection
It sprays forwards, the air after heat exchange to be sent out with heat exchanging air duct is mixed.Since the air quantity of centrifugal blower 151 is big,
The air-flow air supplying distance sprayed using puff prot 124 is remote and temperature is consistent with indoor temperature, can after being mixed with the air-flow that exchanges heat
To greatly improve the air supplying distance of heat exchange air-flow so that indoor temperature can be rapidly achieved set temperature, and can make gas
Stream more mitigates, and the violent temperature difference of heat exchange air-flow and ambient enviroment is avoided to bring uncomfortable feeling to user.To ensure to send
The air-flow gone out is soft, and the impression for being blown to human body is more comfortable, accelerates the flowing of room air, and indoor temperature can be made integrally equal
Even decline improves user's wind sense experience, promotes air-supply comfort level.
Wind guide component 152 may include wind turbine connector 153 for connecting with the outlet air end of centrifugal blower 151 and draw
Flow section 154, wherein Drainage Section 154 connects with wind turbine connector 153, inside limit air collecting chamber, to receive centrifugal blower 151
The air-flow of discharge, Drainage Section 154 are provided with the exhaust outlet towards air ejection member 120, so that the air-flow of air collecting chamber feeds to air ejection member
120 air feed chamber 125.The air-flow that air mixing device 150 generates is fed to air ejection member by wind guide component 152 with windage small as possible
120。
The wind turbine connector 153 of Drainage Section 154 vertically is in integrally scroll casing shape to lateral exhaust outlet, reduces air-flow and is collecting
Windage in air cavity.
The wind turbine connector 153 of wind guide component 152 is connected to the exhaust outlet of spiral case 157, the start-up portion of Drainage Section 154 from
Wind turbine connector 153 is tapered along airflow direction, to accelerate the wind speed that air-flow enters air collecting chamber, the interlude of Drainage Section 154 at
Helical form, the airflow direction guiding that centrifugal blower 151 is discharged is laterally.The transverse section of Drainage Section 154 and air ejection member 120
Connect, inside forms air collecting chamber, and end is provided with the exhaust outlet towards air ejection member 120, so that the air-flow of air collecting chamber feeds to confession
Wind chamber 125.Wind guide component 152 is whole can to reduce windage of the air-flow in air collecting chamber, it is made to form vortex, energy in air collecting chamber
It is enough successfully to lead to air feed chamber 125 from air collecting chamber.
