122 edges to connect with annular inner wall 121 form puff prot 124.
Aeration device 150 is set to one end of shell, has the fresh wind tube 158 and fresh air for leading to fresh air source environment
Wind turbine 151.Fresh-air fan 151 is configured to sucking and comes from the fresh air of fresh wind tube 158, and feeds to the air feed of air ejection member
Chamber so that fresh air sprays forward from puff prot, and surrounding air is driven to be drawn through exhausting hole 123, thus with by first
The air by heat exchange that air outlet 133 is sent out mixes in front of shell.
For fresh wind tube 158 for being connected to inside and outside the working environment of indoor unit 100, air inlet end (head end) can be set to room
The air opening end (end) of (or in other environment with fresh air source) outside, fresh wind tube 158 is set to the one of shell
It holds on end face.That is, can have the interface knot of setting fresh wind tube 158 on a side end face (such as new fan housing 113) for shell
Structure.The air inlet of fresh wind tube 158 can be arranged downward.For example, fresh wind tube 158 includes the water extended from shell to hull outside
Flat section, and the vertical section that is extended downwardly from the end of horizontal segment can prevent rainwater etc. from entering inside air-conditioning and space interior.
In some alternate embodiments, fresh wind tube 158 can protrude horizontally up outdoor, it is preferred to use the form of hose, the shape of fresh wind tube 158
It can be configured as needed.
New fan housing 133 removably covers the outside for being buckled in fresh-air fan 151, and the end of fresh wind tube 158 is set to newly
On the end face of fan housing.
Aeration device 150 can also include：Wind guide component 152.Fresh-air fan 151 preferentially uses centrifugal blower.In the feelings
Under condition, the rotation axis of centrifugal blower 151 can be arranged in parallel with the rotation axis of cross flow fan, to by lateral air-flow to
Lower guiding.Such as the air intake of centrifugal blower 151, towards the end of fresh wind tube 158, outlet air end is provided towards lower section, centrifugation
Wind turbine 151 and the heat exchanging chamber where heat-exchanger rig 140 are mutually isolated.
Wind guide component 152 is connected between the air outlet and air ejection member 120 of fresh-air fan 151, with to fresh-air fan
151 air-flow is guided.
Centrifugal blower 151 can be from side to sucking surrounding air, the air ejection member 120 from the lower section of the first air outlet 133
Puff prot 124 spray.Power source of the centrifugal blower 151 as mixed general mood stream ensure that the air jet speed of air ejection member 120
Degree.
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 of centrifugal blower 151 is towards fresh air
The end of pipe 158 ensures that air-flow can equably be full of the import interface of impeller 156, reduces flow losses.Centrifugal blower 151
When impeller 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 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
After being discharged, negative pressure is formed.Air in fresh wind tube 158 is constantly inhaled into, to form continuous flow.Spiral case 157 is at spiral shell
Shape is revolved, inhales the air that collection is thrown away from impeller 156, and by gradually wealthy sectional area, convert the dynamic pressure of air-flow to static pressure.
Centrifugal blower 151 can be set in new fan housing 113, collect end wall of the gas port towards new fan housing 113, spiral case 157
Exhaust mouth down.
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.Fresh air
Device 150 forms the fresh air duct independently of heat exchanging air duct with air ejection member 120, fresh air outside is sucked, using injection
Mode sprays forwards, and the air after heat exchange to be sent out with heat exchanging air duct is mixed.Due to the air quantity of centrifugal blower 151
Greatly, the air-flow air supplying distance sprayed using puff prot 124 is remote, can be with heat exchange air-flow and after indoor air mixes
Greatly improve the air supplying distance of heat exchange air-flow so that indoor temperature can be rapidly achieved set temperature, to ensure the gas sent out
Flow soft, the impression for being blown to human body is more comfortable, accelerates the flowing of room air, can make indoor temperature it is whole uniformly under
Drop improves user's wind sense experience, promotes air-supply comfort level.
And the fresh air that aeration device 150 sprays can also drive indoor air, can make air-flow more
It mitigates, the violent temperature difference of heat exchange air-flow and ambient enviroment is avoided to bring uncomfortable feeling to user.In wall-hanging air conditioner room
The air-flow of 100 final output of machine is the mixing of the heat exchange air-flow, extraneous fresh air, indoor surrounding air by heat exchange.
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 aeration 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 wind guide component 152 is connected to the exhaust outlet of spiral case 157, the start-up portion of Drainage Section 154 from
