Abstract
The utility model discloses a window air conditioner, which is characterized in that a partition board is arranged in the middle of the window air conditioner; a room external side heat interchanger which is fixed on a chassis is arranged behind the partition board; a wind turbine and a compressor are arranged behind the room external side heat interchanger; the rear end of the crankshaft of the wind turbine is fixed with an axial flow fan; the front end of the crankshaft successively penetrates through the room external side heat interchanger, the partition board, and a spiral casing; the end of the crankshaft is fixed with a centrifugal fan. Because the axial flow fan is arranged behind the room external side heat interchanger, the air which enters the window air conditioner is treated by heat interchange by the room external side heat interchanger, and the treated air is discharged from the window air conditioner by the axial flow fan, so that the airflow separation on the surface of the heat interchanger is reduced, and the airflow noise of the air conditioner is lowered.
Description
The utility model relates to a kind of window air conditioner.
Existing window air conditioner (referring to Fig. 1) in its outside, air enters air-conditioner outside air-conditioner after, all is earlier behind aerofoil fan (1a), passes through outdoor heat exchanger (2a) again and is discharged to outside the window air conditioner.Under this structure, the flow velocity that air flows through the windward side of whole outdoor heat exchanger (2a) is very uneven, flow separation takes place when outdoor heat exchanger (2a) fin is surperficial because phase mutual interference between the air-flow of different in flow rate and high velocity air are flowed through easily, thereby the generation pneumatic noise, this noise becomes one of main noise source of window air conditioner.
The purpose of this utility model is to provide a kind of noise lower low noise type window air conditioner.
The technical scheme that realizes the utility model purpose is (referring to Fig. 2 to Fig. 5), this air-conditioner has chassis (1), be fixed with compressor (2), outdoor heat exchanger (3), wind-powered electricity generation machine (4), indoor heat exchanger (5), dividing plate (61), spiral case (62), casing (63) and circuit control assembly (8) on the chassis (1), casing is provided with air inlet and air outlet, and the arbor front end of wind-powered electricity generation machine (4) is fixed with centrifugal fan (41), the rear end is fixed with aerofoil fan (42); The exhaust end of compressor (2) links to each other with the gas end of outdoor heat exchanger (3), the liquid end of outdoor heat exchanger (3) links to each other with an end of first throttle element (91), the other end of first throttle element (91) links to each other with the liquid end of indoor heat exchanger (5), and the gas end of indoor heat exchanger (5) links to each other with the inlet end of compressor (2); The output of circuit control assembly (8) links to each other with the power control terminal of compressor (2) and the power control terminal of wind-powered electricity generation machine (4) respectively; Its design feature is, dividing plate (61) is located at the middle part of air-conditioner, air-conditioner is separated into the front portion of indoor and the rear portion of outside, indoor heat exchanger (5), centrifugal fan (41) is located at the front portion, spiral case (62) contacts with the front end face of dividing plate (61), compressor (2), outdoor heat exchanger (3) and wind-powered electricity generation machine (4) are located at the rear portion, and compressor (2) is located at a side at rear portion, in the middle of wind-powered electricity generation machine (4) is located at, outdoor heat exchanger (3) is located between wind-powered electricity generation machine (4) and the dividing plate (61), the rear end of the motor shaft of wind-powered electricity generation machine (4) is fixed with aerofoil fan (42), front end passes the preformed hole (31) in the outdoor heat exchanger (3), dividing plate (61) and spiral case (62) are fixed with centrifugal fan (42) on its termination.
The principle that the utility model outside part air flows is: when aerofoil fan (42) turns round under the drive of wind-powered electricity generation machine (4), air in the window air conditioner is discharged to outside the window air conditioner, thereby between outdoor heat exchanger (3), aerofoil fan (42) and shell (63), form a negative pressure cavity, air outside the window air conditioner is under the promotion of atmospheric pressure, by the outside part that the air intake grid on the shell (63) enters window air conditioner, flow through outdoor heat exchanger (3) again and add in the aforesaid negative pressure cavity.Because negative pressure in the whole windward side of outdoor heat exchanger (3) is identical, so air flows through the whole windward side of outdoor heat exchanger (3) under the promotion of atmospheric pressure flow velocity also is identical.Simultaneously, because flow velocity is even, the high velocity air of the part that exists in the old-fashioned window air conditioner will can not produce at this, thereby original flow separation that occurs in outdoor heat exchanger fin surface is also significantly reduced.Corresponding pneumatic noise also just greatly reduces.
Referring to Fig. 6 and Fig. 7, this air-conditioner also can have cross valve (7), second restricting element (92) and check valve (93); The power control terminal of cross valve (92) links to each other with the output of circuit control assembly (8), the exhaust end of compressor (2) is connected with outdoor heat exchanger (3) by cross valve (7) or is connected with indoor heat exchanger (5), promptly, the high-pressure mouth (71) of cross valve (7) links to each other with the exhaust end of compressor (2), the low pressure port (72) of cross valve (7) links to each other with the inlet end of compressor (2), the first exhaust return-air mouth (74) of cross valve (7) links to each other with the gas end of outdoor heat exchanger (3), and the second exhaust return-air mouth (73) links to each other with the gas end of indoor heat exchanger (5); Be provided with second restricting element (92) and check valve (93) between indoor heat exchanger (5) liquid end and the first throttle element (91), the liquid end that is indoor heat exchanger (5) links to each other with an end of second restricting element (92), the other end of second restricting element (92) links to each other with an end of first throttle element (91), goes back and be connected to check valve (93) between the two ends of second restricting element (92).
