In some embodiments of the invention, as shown in Figure 3 and Figure 7, drainage air ducting 50 is included extremely
Few three air-ducting rings.At least three air-ducting rings set gradually between the second air inlet and air outlet, and at least
Three central collar aperture of air-ducting ring are interconnected, and to form insertion air channel, insertion air channel connects the second air inlet
And air outlet.The heat friendship in connection centrifugal blower 30 and insertion air channel is formed between the adjacent air-ducting ring of each two
Wind air channel is changed, the air-flow from centrifugal blower 30 is guided to insertion air channel and from the second air inlet
Air-flow mixes.Further, the width in heat exchange wind air channel can be gradually reduced along the direction of air current flow.
When centrifugal blower 30 works, the negative pressure that can be formed in insertion air channel from the second air inlet introduce not with change
Hot device 40 carries out the air-flow of heat exchange, so that the gas after being exchanged heat from the first air inlet and via heat exchanger 40
Stream mixes with the air-flow from the second air inlet to insertion air channel, so as to blow out more soft gaseous mixture
Stream.The drainage air ducting 50 is particularly suitable for being used cooperatively with centrifugal blower 30, so that from centrifugal blower 30
Air outlet outflow wind more swimmingly enter drainage air ducting 50.
The drainage air ducting 50 of the present embodiment may also include wind path wall 54, its spiral case with centrifugal blower 30
32 are fixedly connected or are integrally formed, and individually or with housing 20 diversion air duct are limited jointly, so as to come from
The air-flow of centrifugal blower 30 all enters insertion air channel from heat exchange wind air channel.
In some embodiments of the invention, as shown in Figures 1 to 5, the first air inlet is arranged at housing 20
Forward upper or upper back；Second air inlet is arranged at the back lower of housing 20；Air outlet is set
In the lower front of housing 20.
For example, before housing 20 includes rear shell 21 and is removably installed at the forward direction opening of rear shell 21
Panel 22.The top of front panel 22 offers the first air inlet, and bottom offers air outlet.Air outlet court
Oliquely downward, its angle of inclination is 4 ° to 40 °, preferably 10 °.Air outlet is arranged such, cooperation is drawn
The structure design of conductance wind apparatus 50 so that from the enough forward downward flowings of wind energy that air outlet is sent out.Enter one
Step ground, can open or close the shutter 24 of the first air inlet in the setting of the first air inlet of front panel 22,
For example, the lower edge of shutter 24 is rotatably installed on front panel 22.
Shell 21 can have rear wall 211, perisporium and accommodate cavity wall 212 afterwards.The bottom of rear wall 211 offers second
Air inlet.Accommodate cavity wall 212 to extend forward from the inner surface of rear wall 211, centrifugal blower 30 is contained to limit
With the receiving space of drainage air ducting 50.The rear surface top of rear wall 211 is settable wallboard 80,
The indoor apparatus of air conditioner can be fixed on wall by wallboard 80.Further, as shown in figure 5,
Surface lower portions can cave inward after rear wall 211, and the second air inlet is formed in the rear surface lower portions of rear wall 211,
So that air enters the second air inlet from surface lower portions after rear wall 211 with gap between the walls.
Centrifugal blower 30 can be single inhalation type centrifugal fan, be installed on the top of receiving space, its air inlet
Towards the first air inlet.Drainage air ducting 50 is installed on the bottom of receiving space.Heat exchanger 40 is one
Or multiple plate type heat exchangers, it is arranged between the air inlet of centrifugal blower 30 and first.It is many in heat exchanger 40
In the case of individual plate type heat exchanger, multiple plate type heat exchangers vertically set gradually.For example, board-like change
The quantity of hot device can be two, the first plate-type heat-exchange that area is larger, length is larger being respectively below
Device 41 and the second plate type heat exchanger 42 that the area in top is smaller, length is shorter, to make full use of shell
The shape of body 20, expands the heat exchange area of heat exchanger 40, improves heat exchange efficiency.First plate type heat exchanger 41
Housing 20 can be installed on the second plate type heat exchanger 42 by with support 43
In this embodiment, wind path wall 54 limits diversion air duct jointly with rear wall 211.Specifically, from
The spiral case 32 of heart blower fan 30 may include front side spiral case and the week side of boss spiral case extended back from front side spiral case, preceding
The air inlet of centrifugal blower 30, spiral case 32 and the rear wall 211 of centrifugal blower 30 are offered on the spiral case of side
Inner surface limits spiral case air channel.Wind path wall 54 may include that front side wind path wall and the past side wind path wall prolong backward
The week side of boss wind path wall for stretching out.Front side wind path wall is preferably integrally formed with front side spiral case, the week side of boss wind path wall preferably with
The week side of boss spiral case is integrally formed, so that air-out is more smooth.The lower part of the week side of boss wind path wall is on the wind path wall of front side
Projection be preferably semicircular arc so that the air-flow from centrifugal blower 30 all enters from heat exchange wind air channel
Enter insertion air channel.In some alternate embodiments of the invention, the spiral case 32 of centrifugal blower 30 only includes
Front side spiral case, wind path wall 54 only includes front side wind path wall.It is empty that spiral case 32 and wind path wall 54 are covered on receiving
Between opening at, with accommodate cavity wall 212, rear wall 211 jointly limit the air channel of spiral case 32 and diversion air duct.
Specifically, at least three air-ducting rings are respectively rear air-ducting ring 51, preceding air-ducting ring 53, and positioned at preceding
One or more middle air-ducting rings 52 between air-ducting ring 53 and rear air-ducting ring 51.The adjacent wind-guiding of each two
In circle, in the central collar aperture of air-ducting ring air-ducting ring of the insertion in front in rear, rear air-ducting ring 51
Extend forward from the mouth edge of the second air inlet, be integrally formed with rear wall 211.Opened on the wind path wall of front side
Through hole is provided with, preceding air-ducting ring 53 extends forward from the bore edges of through hole, is integrally formed with wind path wall 54.
So set, not only significantly improve the convenience of processing, and be advantageously used for the flowing of air-flow, improve air-flow
The smoothness of flowing, reduces noise.Further, in this embodiment, the quantity of air-ducting ring is 3,
Respectively preceding air-ducting ring 53, middle air-ducting ring 52 and rear air-ducting ring 51.Middle air-ducting ring 52 can be by more
Individual connection sheet is installed in rear air-ducting ring 51.Multiple connection sheets also have the effect of guiding air-flow.In this hair
In bright embodiment, indoor apparatus of air conditioner may also include drip tray 90, be fixed on housing 20 and/or preceding air-ducting ring 53,
And between heat exchanger 40 and preceding air-ducting ring 53.Drip tray 90 can extend along horizontal transverse direction, and
Its bottom land is slightly inclined setting, so that the other end of the bottom land one end less than bottom land, can be in the groove of drip tray 90
The relatively low one end in bottom opens up the apopore for connecting condensate draining pipe.
In other embodiments of the invention, as shown in Figure 6 to 8, the first air inlet is two, if
