Rake angle is 4 ° to 40 °, preferably 10 °.Air outlet, the structure design of cooperation drainage air ducting 50 is arranged such so that from
The wind energy that air outlet is sent out reaches forward downward flowing.Further, also can shutter 24 be set in the first air inlet, with guiding
The first air inlet of air-flow and/or either on or off.Shutter 24 can be rotatably mounted to shell 20 at its lower edge.
Rear shell 21 can have rear wall 211, peripheral wall and accommodate cavity wall 212.211 lower part of rear wall offers the second air inlet.Hold
Cavity wall 212 of receiving extends forward from 211 inner surface of rear wall, to limit the receiving sky for containing centrifugal blower 30 and draining air ducting 50
Between.The rear surface top of rear wall 211 may be provided with wallboard 60, which can be fixed on wall by wallboard 60
On wall.Further, as shown in figure 4,211 rear surface lower part of rear wall can be recessed inwardly, the second air inlet is formed in rear wall 211
Rear surface lower part, so that air enters the second air inlet from 211 rear surface lower part of rear wall and gap between the walls.Centrifugal blower
30 can be unidirectional centrifugal fan, be installed on the top of accommodation space.Drainage air ducting 50 is installed on the lower part of accommodation space.
Fig. 5 is the schematic diagram of micro-channel heat exchanger in air conditioner indoor unit shown in Fig. 1, as shown in figure 5, in the present invention
Some embodiments in, the side that every micro-channel flat 41 extends every micro-channel flat 41 along horizontal transverse direction is parallel to
The rotation axis of centrifugal blower 30.It is provided with fin between every two adjacent micro-channel flats 41.The micro-channel heat exchanger 40
It can be installed in shell 20 by fixing bracket 43.In some alternate embodiments, every micro-channel flat 41 also can be along perpendicular
Histogram is to extension.
The part of the rotation axis higher than centrifugal blower 30 of shell 20 is in the rotation axis perpendicular to centrifugal blower 30
Projection in plane is tapered from bottom to top, as shell 20 is round, approximate circle or oval in being projected as on its axis
Shape etc..Micro-channel heat exchanger 40 in the embodiment further includes two headers 42, is arranged the two of every micro-channel flat 41
End；Each header 42 includes vertical pipe section 421 and the bending tube section 422 being bent upwards from the upper end of vertical pipe section 421.Two
The distance between bending tube section 422 tapers into from bottom to top, so that micro-channel heat exchanger 40 is installed in shell 20, Ci Zhongshe
Setting can be such that micro-channel flat 41 as much as possible is installed in shell 20, significantly increase heat exchange area.Further, each afflux
It is provided with partition in pipe 42, to control the flow direction of refrigerant in micro-channel heat exchanger 40.
In some embodiments of the invention, drainage air ducting 50 includes at least three air-ducting rings.At least three wind-guidings
Circle is set gradually between the second air inlet and air outlet, and the central collar aperture of at least three air-ducting rings is interconnected, to be formed
Insertion air channel, insertion air channel are connected to the second air inlet and air outlet.Connection centrifugation wind is formed between each two adjacent air-ducting ring
The heat exchange wind air channel of machine 30 and insertion air channel guides the air-flow from centrifugal blower 30 to insertion air channel and from second
The air-flow of air inlet mixes.Further, the width of heat exchange wind air channel can be gradually reduced along the direction that air-flow flows.When from
When heart wind turbine 30 works, the negative pressure that can be formed in insertion air channel is not carried out with micro-channel heat exchanger 40 from the introducing of the second air inlet
The air-flow of heat exchange, so that the air-flow after exchanging heat from the first air inlet and via micro-channel heat exchanger 40 is entered the wind with from second
The air-flow of mouth is mixed to insertion air channel, to blow out more soft mixed airflow.The drainage air ducting 50 is particularly suitable for
It is used cooperatively with centrifugal blower 30, so that the wind flowed out from the air outlet of centrifugal blower 30 more swimmingly enters drainage wind-guiding dress
Set 50.
Drainage air ducting 50 may also include wind path wall 54, be fixedly connected with the spiral case 32 of centrifugal blower 30 or one at
Type individually or with shell 20 limits diversion air duct jointly, so that the air-flow from centrifugal blower 30 is all from heat exchange wind
Air duct enters insertion air channel.For example, wind path wall 54 can limit diversion air duct jointly with the rear wall 211 of shell 20.Specifically, from
The spiral case 32 of heart wind turbine 30 may include front side spiral case and the side spiral case that is extended back from front side spiral case, be opened up on the spiral case of front side
There are the import of centrifugal blower 30, the spiral case 32 of centrifugal blower 30 to limit spiral case air duct with the inner surface of rear wall 211.Wind path wall 54
It may include front side wind path wall and the side wind path wall extended back from preceding side wind path wall.Front side wind path wall preferably with front side spiral case
It is integrally formed, side wind path wall is preferably integrally formed with side spiral case, so that outlet air is more smooth.The lower part of side wind path wall
Projection on the wind path wall of front side is preferably semicircular arc, so that the air-flow from centrifugal blower 30 is all from heat exchange wind air channel
Into insertion air channel.In some alternative embodiments of the invention, the spiral case 32 of centrifugal blower 30 only includes front side spiral case, wind
Road wall 54 only includes front side wind path wall.Spiral case 32 and wind path wall 54 are covered on the opening of accommodation space, with accommodate cavity wall 212,
Rear wall 211 limits spiral case air duct and diversion air duct jointly.
Specifically, air-ducting ring 51, preceding air-ducting ring 53 after at least three air-ducting rings are respectively, and it is located at 53 He of preceding air-ducting ring
Air-ducting ring 52 among one or more between air-ducting ring 51 afterwards.In each two adjacent air-ducting ring, it is in the air-ducting ring at rear
It is inserted into the central collar aperture of the air-ducting ring in front.Air-ducting ring 51 extends forward from the mouth edge of the second air inlet afterwards, with
It is integrally formed with rear wall 211.Through-hole is offered on the wind path wall of front side, preceding air-ducting ring 53 extends forward from the bore edges of through-hole,
To be integrally formed with wind path wall 54.In this way, not only significantly improving the convenience of processing, and it is advantageously used for the stream of air-flow
It is dynamic, the smoothness of air-flow flowing is improved, noise is reduced.Further, in this embodiment, the quantity of air-ducting ring is 3, respectively
For preceding air-ducting ring 53, intermediate air-ducting ring 52 and rear air-ducting ring 51.Intermediate air-ducting ring 52 is led after being installed on by multiple connection sheets
On solar or lunar halo 51.Multiple connection sheets also have the function of guiding air-flow.
In embodiments of the present invention, air conditioner indoor unit may also include drip tray 70, be fixed on shell 20 and/or preceding air-ducting ring
53, and between micro-channel heat exchanger 40 and preceding air-ducting ring 53.Drip tray 70 can extend along horizontal transverse direction, and its slot bottom
It is slightly inclined setting, so that slot bottom one end is less than the other end of slot bottom, can open up and be used in relatively low one end of slot bottom of drip tray 70
Connect the apopore of condensate draining pipe.
So far, although those skilled in the art will appreciate that present invention has been shown and described in detail herein multiple shows
Example property embodiment still without departing from the spirit and scope of the present invention, still can according to the present disclosure directly
