Specific embodiment
Fig. 1 is the schematic diagram of air conditioner indoor unit according to an embodiment of the invention, and Fig. 2 is air-conditioning shown in Fig. 1
The schematic cross sectional views of indoor unit.As depicted in figs. 1 and 2, the embodiment of the invention provides a kind of air conditioner indoor unit.The air conditioning chamber
Interior machine may include shell 20, centrifugal blower 30, heat exchanger 40 and drainage air ducting 50.Shell 20 can have the first air inlet,
Second air inlet and air outlet.Centrifugal blower 30 may include impeller 31 and spiral case 32, be set in shell 20, rotation axis or
The extended line of the rotation axis is passed through from the first air inlet, so that its air inlet the first air inlet of direction, and be configured to promote
Air-flow is flowed from the first air inlet to air outlet.
At least partly heat exchange section of heat exchanger 40 is in tabular, and at least partly heat exchange section is perpendicular to centrifugal blower 30
Rotation axis, and between centrifugal blower 30 and the first air inlet.Specifically, heat exchanger 40 is a plate heat exchanger；?
In other embodiments, heat exchanger 40 includes multiple plate heat exchangers, and multiple plate heat exchangers are along perpendicular to centrifugal blower 30
The direction of rotation axis set gradually, and multiple plate heat exchangers are parallel with one another.
Drainage air ducting 50 may be disposed in shell 20, be configured to the air-flow from centrifugal blower 30 (i.e. from the
One air inlet and via heat exchanger 40 exchange heat after centrifugal blower 30 air-flow) with the air-flow from the second air inlet import in it with
It is mixed, and makes mixed air-flow to have velocity component on the direction of rotation axis for being parallel to centrifugal blower 30
Mode blows out from air outlet.
Centrifugal blower 30 and flat heat exchanger 40 not only significantly improve the air output of air conditioner indoor unit, accelerate room
Interior wind circulation rate, and improve the heat exchange efficiency of heat exchanger 40 Yu air；The volume of the air conditioner indoor unit can also be made smaller, just
Installation, movement in air conditioner indoor unit；And it is convenient to manufacture in various, rakish air conditioning chamber
Machine, for example, projection of the shell 20 in a plane perpendicular to the rotation axis of centrifugal blower 30 is round or oval, so that
Entire air conditioner indoor unit unique outlook is beautiful, is totally different from the wall-hanging indoor unit of air conditioner of existing strip, meets user
Personalized aesthetic requirement.It is needing herein it is noted that throwing of some shells 20 in a plane perpendicular to its axis
Shadow is approximate circle, it should also belong to circular special shape, that is, belong to one kind of present inventive concept.Draining air ducting 50 can
The wind for blowing out the air conditioner indoor unit is softer.
Particularly, in embodiments of the present invention, in order to control the first air inlet, which may also include
Shutter 60 and translation mechanism 70.Translation mechanism 70 is configured to drive shutter 60 along the rotation axis for being parallel to centrifugal blower 30
Direction it is mobile, to open or close the first air inlet.For example, control translation mechanism 70 is outside in air conditioner indoor unit work
Mobile shutter 60, to open the first air inlet.It, can be by changing shutter 60 and the during air conditioner indoor unit work
Spacing between one air inlet controls intake.When closing air conditioner indoor unit, control translation mechanism 70, which moves inward, to be blocked
Plate 60, to close the first air inlet.
In some embodiments of the invention, the first air inlet is set to the forward upper of shell 20, and the second air inlet is set
It is placed in the back lower of shell 20, air outlet is set to the lower front of shell 20, and the rotation axis of centrifugal blower 30 is along water
Flat longitudinal direction extends.For example, shell 20 includes rear shell 21 and before being removably installed at the forward opening of rear shell 21
Plate 22.
The top of front panel 22 offers the first air inlet, and lower part offers air outlet.Air outlet obliquely downward, inclines
Rake angle is 4 ° to 40 °, preferably 10 °.Air outlet is arranged such, the structure of cooperation drainage air ducting 50 designs, so that from
The wind that air outlet is sent out being capable of forward downward flowing.
Rear shell 21 can have rear wall 211, peripheral wall 212 and accommodate cavity wall 213.211 lower part of rear wall offers the second air inlet.
Peripheral wall 212 is extended anteriorly out from the edge of rear wall 211.It accommodates cavity wall 213 to extend forward from 211 inner surface of rear wall, to limit
It contains centrifugal blower 30 and drains the accommodation space of air ducting 50.The rear surface top of rear wall 211 may be provided with wallboard 80,
The air conditioner indoor unit can be fixed on wall by wallboard 80.Further, as shown in figure 3, under 211 rear surface of rear wall

Logical, to form insertion air channel, insertion air channel is connected to the second air inlet and air outlet.The company of being formed between every two adjacent air-ducting ring
The heat exchange wind air channel of logical centrifugal blower 30 and insertion air channel, by the air-flow from centrifugal blower 30 guide to insertion air channel with
Air-flow mixing from the second air inlet.Further, the width of heat exchange wind air channel can be along the direction that air-flow flows gradually
It reduces.When centrifugal blower 30 works, the negative pressure that can be formed in insertion air channel from the second air inlet introduce not with heat exchanger 40
The air-flow of heat exchange is carried out, so as to from the first air inlet and via the air-flow after the heat exchange of heat exchanger 40 and come from the second air inlet
Air-flow mixed to insertion air channel, thus the more soft mixed airflow of blowout.The drainage air ducting 50 be particularly suitable for
Centrifugal blower 30 is used cooperatively, so that the wind flowed out from the air outlet of centrifugal blower 30 more swimmingly enters drainage air ducting
50。
The drainage air ducting 50 may also include wind path wall 54, be fixedly connected with the spiral case 32 of centrifugal blower 30 or integrated
Molding, individually or with shell 20 ordinatedly limits diversion air duct, so that the air-flow from centrifugal blower 30 is all handed over from heat
It changes wind air duct and enters insertion air channel.Specifically, the spiral case 32 of centrifugal blower 30 may include front side spiral case and from front side spiral case backward
The side spiral case and rear side spiral case extended.The import of centrifugal blower 30, the snail of centrifugal blower 30 are offered on the spiral case of front side
Shell 32 limits spiral case air duct.The week that wind path wall 54 may include rear side wind path wall 541, extend anteriorly out from rear side wind path wall 541
Side wind path wall 542, and it is installed on the front side wind path wall 543 at the forward opening of side wind path wall 542.Rear side wind path wall 541
It is preferred that being integrally formed with rear side spiral case, side wind path wall 542 and side spiral case are integrally formed, so that outlet air is more smooth.Side
Projection of the lower part of wind path wall 542 on rear side wind path wall 541 is preferably semicircular arc, so that the gas from centrifugal blower 30
Stream all enters insertion air channel from heat exchange wind air channel.
At least three air-ducting rings are respectively preceding air-ducting ring 51, rear air-ducting ring 53, and are located at preceding air-ducting ring 51 and rear wind-guiding
The intermediate air-ducting ring 52 of one or more between circle 53.In every two adjacent air-ducting ring, the air-ducting ring insert division in rear
In in the central collar aperture of the air-ducting ring in front.Air-ducting ring 53 extends forward from the mouth edge of the second air inlet afterwards, with rear wall
211 are integrally formed.Through-hole is offered on rear side wind path wall 541, is passed through with air-ducting ring 53 after permission.It is opened on front side wind path wall 543
Equipped with through-hole, preceding air-ducting ring 51 extends forward from the bore edges of through-hole, to be integrally formed with front side wind path wall 543.It sets in this way
It sets, significantly improves the convenience of processing.Further, in this embodiment, the quantity of air-ducting ring is 3, respectively leading
