Fig. 7 is the first air-supply assembly 130 in the wall-hanging indoor unit of air conditioner 100 according to the utility model one embodiment
The structure diagram blown with the second blower part 150 to jet component 120.First air-supply assembly 130 includes：First centrifugation wind
131 and first wind guide component 136 of machine, the second air-supply assembly 150 include：Second centrifugal blower 151 and the second wind guide component
156.In order to ensure air jet velocities, first air-supply assembly 130 and the second air-supply assembly 150 of the present embodiment employ from
Power source of the heart wind turbine as heat exchange air-flow.
First centrifugal blower 131 is converted to the principle of potential energy according to kinetic energy, using high-speed rotating first impeller 133 by gas
Body accelerates, and then slows down, changes flow direction, kinetic energy is made to be converted into potential energy.First centrifugal blower 131 generally comprises the first collection gas port
132nd, the first impeller 133, the first spiral case 134.First collection gas port 132 of the first centrifugal blower 131 act as guarantee air-flow energy
The import interface of the first impeller 133 is equably full of, reduces flow losses, in the present embodiment, the of the first centrifugal blower 131
The direction of one collection gas port 132 to the first impeller 133 is tapered, forms horn mouth, can try one's best heat exchanger accommodating chamber 144 is interior with changing
The air that hot device 140 exchanges heat sucks the first impeller 133.First impeller 133 of the first centrifugal blower 131 is by the first high-speed electric expreess locomotive
When 135 drives rotate with the axis, the gas between the first impeller 133 rotates with the first impeller 133 and obtains centrifugal force, and gas is thrown out of
First impeller 133, into the first spiral case 134, the gas pressure intensity in the first spiral case 134, which increases, is directed to discharge.Interlobate gas
After body is discharged, negative pressure is formed；First collection gas port 132 outside heat exchanger accommodating chamber 144 in 140 air of heat exchanger constantly by
Sucking, so as to form continuous flow.
The first impeller 133 and the first spiral case 134 of first centrifugal blower 131 are arranged at what partition plate 143 was limited with case 112
In space, and the exhaust outlet of the first spiral case 134 is towards the side wall of housing 110；The air inlet and first of first wind guide component 136
The exhaust outlet of spiral case 134 connects.First spiral case 134 helically, is inhaled the air that collection is thrown away from the first impeller 133, and is led to
Gradually wealthy sectional area is crossed, the dynamic pressure of air-flow is converted into static pressure.
