In sum, the inlet shell 120 of indoor apparatus of air conditioner 10 is substantially cylindrical, and type is less, effectively saves installing space, and aesthetic in appearance. Blower part 14 is rotatably coupled inlet shell 120 so that the air-flow that diagonal flow fan 122 exports 140c blowout from jet-impingement could alter that blowing direction, reduces the cold wind sense of indoor apparatus of air conditioner 10, and then improves the blowing comfortableness of indoor apparatus of air conditioner 10.
Air inlet 120a includes the multiple through hole 120g being distributed along the circumferencial direction equi-spaced apart of inlet shell 120 so that indoor apparatus of air conditioner 10 air intake is uniform. First air channel 12b of indoor apparatus of air conditioner 10, the second air channel 12c and the 3rd air channel 12d axially setting gradually along cylindric inlet shell 120, the space occupying inlet shell 120 is less, air channel 12a coordinates columned inlet shell 120 rationally to arrange, be conducive to the type miniaturization of indoor apparatus of air conditioner 10, and aesthetic in appearance. Second air channel 12c along the axial cross sectional shape of inlet shell 120 in the shape changed along the air-flow exit direction convergent of indoor apparatus of air conditioner 10 so that flow through the airflow speed increasing of the second air channel 12c.
Specifically, gas enters in the first air channel 12b of inlet shell 120 from air inlet 120a, by entering the second air channel 12c after spiral case 122a, gas is by oblique flow wind wheel 122b work done supercharging, and after form high pressure draught through the further rectification supercharging of stator blade element 122d, high pressure draught is expelled to forward the 3rd air channel 12d from the circular passage 12e of stator blade element 122d, rectification further across the diversion component 128 in the 3rd air channel 12d is led, make air-flow direction of motion smooth and continuous be changed into vertical direction from horizontal direction, the gas access 140b of blower part 14 is entered finally along procapsid 120d. the curved surface 128a of diversion component 128 offers water conservancy diversion groove 128b so that air-flow divides the gas access 140b at the two ends to blower part 14 equably while smooth and continuous turns to.
Being formed with external channel 16 between blower part 14 and inlet shell 120, the area of external channel 16 is the air-out area of indoor apparatus of air conditioner 10, and therefore the air-out area of the indoor apparatus of air conditioner of the relatively conventional long strip type of indoor apparatus of air conditioner 10 is bigger.
As shown in Fig. 1 and Figure 10, when blower part 14 is in the opposite upper parts position of inlet shell 120, external channel 16 is positioned at above inlet shell 120. Blower part 14 is point to procapsid 120d from back casing 120e from windward side 140h to the pointing direction of leeward side 140i, namely exports the 140c airflow direction sprayed from jet-impingement and points to procapsid 120d from back casing 120e.
As shown in Figure 3 and Figure 5, when blower part 14 is in the opposite nose position of inlet shell 120, now being exported the 140c airflow direction sprayed from jet-impingement is blown toward front lower portion from the front upper part of inlet shell 120.
By jet-impingement outlet 140c discharge is relatively high speed pressure-air, viscosity due to fluid, along air motion direction, export 140c rear portion at jet-impingement and form a negative pressuren zone, there is the drive surrounding air trend to its motion, the cross section profile of windward side 140h is a convex outward, according to the Coanda effect in hydrodynamics, air outside negative pressuren zone is in negative pressuren zone motor process, original direction of motion can be changed and depend on windward side 140h wall motion, the final directed flow that formation is stable in external channel 16, and export associated movement after the 140c relatively high pressure gas discharged mixes with by jet-impingement.
