Accompanying drawing explanation
Fig. 1 is principle of work and power schematic diagram of the present invention.
Detailed description of the invention
Shown in Fig. 1, be a kind of automotive air-conditioning system eliminating peculiar smell of the present invention, comprise conditioning control unit, and provide the storage battery 1 of working power for described conditioning control unit; First mouth of described storage battery 1 is connected with ignition lock 2, and its second mouth is connected with blowing engine 18 by the open contact switch of relay 19; First mouth of described ignition lock 2 connects one to one respectively by the control signal input end d of automatic control switch 3 and energy-saving control switch 4 and described conditioning control unit and control signal input end e, and its second mouth is connected with the control signal mouth c of described conditioning control unit by the coil of described relay 19; The control signal mouth a of described conditioning control unit is connected with the control input end of described blowing engine 18 by air compressor control module 16, and the control signal mouth b of described conditioning control unit is connected with the control input end of described blowing engine 18 by resistance 17; The signal input part of described conditioning control unit is also connected to the air inlet cycle mode control motor 8 of band position transduser, and the streamer mode of band position transduser controls motor 9.Wherein, when energy-saving control switch 4 closes, reduce to some extent relative to the state load of automatic control switch 4, under equal conditions the turnon time of electromagnetic clutch for compressor postpone to some extent, drum according to circumstances rotating speed also decrease, can save fuel oil, improve economy.
Wherein, air inlet cycle mode with position transduser controls motor 8, and the streamer mode control motor 9 of band position transduser is all made up of motor and position transduser, can change air inlet cycle mode or streamer mode by the direction of current changing motor, position transduser makes conditioning control unit revise position as feedback signal.In figure, the 5V VREF (Voltage Reference) that Vc provides for conditioning control unit, Vs is signal voltage, and E2 is the grounding jumper of sensor by conditioning control unit.
During work, close at ignition lock 2, open in the beginning 30S of air-conditioning (namely automatic control switch 3 or energy-saving control switch 4 close), conditioning control unit exports 12V voltage by control signal mouth b, blower motor 18 low speed and reverse, it is outer circulation that air inlet cycle mode control motor 8 with position transduser controls air inlet cycle mode, and the peculiar smell in evaporator and pipeline, to dispatch outside car, is discharged outside car by air in car.After 30S, air-conditioning enters normal working, and first conditioning control unit controls its signal output part c, provides working power to blower motor 18; The rotating speed of blowing engine 18 is then controlled by control signal mouth a output duty cycle signal by conditioning control unit, and duty cycle signals is larger, then conduction amount is larger, blower speed is higher for air compressor control module 16 (for large power triode).
