The wall-hanging indoor unit of air conditioner of the present embodiment passes through motor forward/backward rotation and moves, to drive wind wheel 30 clockwise or inverse
Hour hands rotate, and realize cold air during refrigeration and send obliquely upward, when heating, hot-air is oliquely downward sent.So that indoor temperature
More uniform.
Specifically, the operation principle of the wall-hanging indoor unit of air conditioner of the present embodiment is：When air conditioner room unit heats,
Heat exchanger produces heat, and motor rotates forward, and drives wind wheel 30 to rotate clockwise, the first wind wheel section 31 and the second wind wheel area
Section 32 is all rotated in the clockwise direction, and air is entered from the first inlet scoop 25 due to the drive of wind wheel 30, and with heat exchanger first
Part 23 carries out heat exchange.The blade of the wherein first wind wheel section 31, its blade profile curve bending extension direction is also clockwise, with
Wind wheel 30 direction of rotation is consistent, and the first wind wheel section 31 can produce air-flow, and the flow direction of this air-flow and the first air channel
Curved bearing of trend is identical, and therefore, the first exhaust air flue 121 being capable of air-out.And the blade of the second wind wheel section 32, its leaf
Type curved bearing of trend is counterclockwise, inconsistent with wind wheel 30 direction of rotation, and the second wind wheel section 32 can not produce gas
Stream, therefore, the second exhaust air flue 122 is unable to air-out.The hot blast that multiple first exhaust air flue 121 produce is finally from the first air outlet
21 outflow, and the second air outlet 22 do not have distinguished and admirable go out.Hot blast from obliquely downward to after send, due to light, the meeting than indoor cold air
Flow up, accelerate indoor air flow and circulate so that indoor temperature is more uniform.
When air conditioner room unit freezes, heat exchanger produces cold, and motor rotates backward, and drives wind wheel 30 to turn counterclockwise
Move, the first wind wheel section 31 and the second wind wheel section 32 all rotate in the counterclockwise direction.The blade of the wherein first wind wheel section 31,
Its blade profile curve bending extension direction is clockwise, inconsistent with wind wheel 30 direction of rotation, and the first wind wheel section 31 can not produce
Air-flow, therefore, the first exhaust air flue 121 is unable to air-out.And the blade of the second wind wheel section 32, its blade profile curve bending extension side
To for counterclockwise, consistent with wind wheel 30 direction of rotation, the second wind wheel section 32 can produce air-flow, simultaneously the flow direction of air-flow
Identical with the second duct-curve bending extension direction, therefore, the second exhaust air flue 122 being capable of air-out.Multiple second exhaust air flue
122 generation cold wind finally flow out from the second air outlet 22, and the first air outlet 21 do not have distinguished and admirable go out.Cold wind is sent by oblique direction
After going out, due to the indoor hot-air weight of ratio, can flow downward, accelerate indoor air flow and circulate so that indoor temperature is more uniform.
Certainly, in other embodiment, because of the bending extension direction of wind wheel 30 blade and exhaust air flue 12
