Heat exchanger 140, is arranged inside housing 110.Heat exchanger 140 and the air progress heat exchange for flowing through it, to change
Flow through the temperature of its air.A part of the heat exchanger 140 as refrigeration system, refrigeration system, which can utilize, compresses kind of refrigeration cycle
To realize, compression kind of refrigeration cycle is circulated real using refrigerant in the compression phase transformation of compressor, condenser, evaporator, throttling arrangement
The transmission of existing heat.Refrigeration system can also set four-way valve, change the flow direction of refrigerant, replace indoor set heat exchanger 140
As evaporator or condenser, refrigeration or heat-production functions are realized.It is art technology due to compressing kind of refrigeration cycle in air conditioner
Known by personnel, this will not be repeated here for its operation principle and construction.
Heat exchanger 140 includes the first heat exchanging segment 1401 and the second heat exchanging segment 1402, wherein the first heat exchanging segment 1401 is arranged at
Close to the position of front panel 114, the second heat exchanging segment 1402 is arranged at the position for the roof for being posted by case 112, and heat exchanger 140 is adopted
With two-part structure, heat exchange area is expanded, improves heat exchange efficiency, and the first heat exchanging segment 1401 and the second heat exchanging segment 1402
Can be by refrigerant line in parallel or in series.When using parallel-connection structure, the first heat exchanging segment 1401 and the second heat exchanging segment
1402 can select to use according to the operational mode of indoor unit 100, such as in normal mode, only open the first heat exchanging segment
1401, in the situation that the first heat exchanging segment 1401 cannot be met the requirements, while open the second heat exchanging segment 1402.In some optional implementations
In example, for the ease of collecting condensed water, the second heat exchanging segment 1402 can be obliquely installed.
First heat exchanging segment 1401 and the second heat exchanging segment 1402 can be with roof air inlet 1162 and side wall air inlets 1161
It is used cooperatively.For example, after the air that roof air inlet 1162 enters exchanges heat with the second heat exchanging segment 1402 first, subsequently into the
First Heat Exchanger accommodating chamber where one heat exchanging segment 1401 exchanges heat with the first heat exchanging segment 1401.
Air-supply assembly includes：Centrifugal blower 131 and wind guide component 136.Centrifugal blower 131 is as gas in indoor unit 100
The power source of flowing, can be configured so that surrounding air enters from top air inlet 1162 and/or side wall air inlet 1161
Exchange heat, discharged after centrifugal blower 131 to airflow downstream, eventually through jet portion in indoor unit and with heat exchanger 140
Part 120 is sent out outside indoor unit 100.Wind guide component 136 is connected to the exhaust outlet and air ejection member 120 of centrifugal blower 131
Between air feed chamber, and for the air-flow that centrifugal blower 131 is discharged to be led into air feed chamber.
Air ejection member 120, is arranged in air outlet 117, and overall is in oval (or track type), air ejection member 120
Center limits exhausting hole 123, the front and rear perforation of the exhausting hole 123.Air ejection member 120 and its size of internal part, specification, can
It is configured with the specification position of the draft capacity according to air-supply assembly centrifugal blower 131 and wind guide component 136.Fig. 3 is root
According to the schematic diagram of air ejection member 120 in the wall-hanging indoor unit of air conditioner 100 of one embodiment of the invention, Fig. 4 is along Fig. 3
The air flow direction figure of the schematic sectional of cutting line A-A interceptions.
Air ejection member 120 includes annular inner wall 121 and annular outer wall 122, and annular inner wall 121 and annular outer wall 122 are common
Above-mentioned oval is formed, and the inner side of annular inner wall 121 is exhausting hole 123.Annular outer wall 122 connects with annular inner wall 121
Edge formed puff prot 124, puff prot 124 be used for the air-flow of air feed chamber 125 is sprayed forward, and cause air outlet 117 after
The air in portion is drawn through exhausting hole 123.
The posterior edges 126 of annular inner wall 121 are to 125 internal recess of air feed chamber, and annular outer wall 122 and annular inner wall
The opposite position of 121 posterior edges 126 has outside flange 127, so that annular outer wall 122 and annular inner wall 121
Posterior edges 126 between gap formed puff prot 124.Posterior edges of the annular inner wall 121 to 125 internal recess of air feed chamber
126 can also have the function that airflow direction guiding, the air-flow in air feed chamber 125 is successfully sent out from puff prot 124.
Annular inner wall 121 extends to form forward continuous abducent Coanda surface from lateral edges 126 thereafter；And ring
Shape outer wall 122 is located at the section curl of the part of the rear side of air ejection member 120, so that the air-flow of air feed chamber 125 is along ring
Shape outer wall 122 after the ejection of puff prot 124, send out forward, and drives extraction to send by the Coanda surface formed along annular inner wall 121
The surrounding air at 117 rear of air port.Annular inner wall 121 extend forward continuous abducent extension angle of inclination can be 5 to
15 degree, angle of inclination is bigger, and the outside expansion rate for the air-flow that puff prot 124 sprays is faster, is tested by substantial amounts of, in annular
Between the extension angle of inclination of wall 121 could be provided as 6 to 10 degree, so it is more advantageous to and the surrounding air in exhausting hole 123
Mixed.
Annular inner wall 121 and annular outer wall 122 limit the annular air feed chamber 125 inside air ejection member 120, ring jointly
Shape inner wall 121 and annular outer wall 122 have respectively two it is intersegmental every horizontal section 128 and connection two sections of horizontal sections 128
Two sections of curved sections 129, wherein the annular of the curved section 129 in two sections of curved sections 129 positioned at 136 side of wind guide component is outer
The air inlet of air ejection member 120 is offered on wall 122, for receiving the air after heat exchange of air-supply assembly offer.It is another
The outside of the curved section 129 of side can set supporting item 146, for preferably fixing the air ejection member 120.
The above-mentioned section of annular inner wall 121 and annular outer wall 122 is formed by the component of multiple connections, is preferable to carry out at some
In example, annular inner wall 121 and annular outer wall 122 can be formed by overall moulded parts.
Puff prot 124 can be continuous annular groove, and in some alternative embodiments, puff prot 124 can also be in annular
Formed on a part of section of inner wall 121 and annular outer wall 122, or the multistage for interval.Such as puff prot 124 can be only
It is arranged in the horizontal section 128 of air ejection member 120 so that jet is more uniform, and can effectively drive exhausting hole 123
Interior surrounding air.In order to improve the effluxvelocity of puff prot 124, the width of puff prot 124 could be provided as 1 to 3mm, pass through
Substantial amounts of test, the width of puff prot 124 can be preferably arranged to 2mm or so, and the puff prot 124 of the dimension width both ensures to change
The jet velocity of thermal current, and the windage loss of heat exchange air-flow can be reduced to the greatest extent, reduce noise.Solid arrow is in Fig. 4
The airflow direction of surrounding air, the airflow direction for the heat exchange air-flow that dotted arrow sprays for puff prot 124.
