Abstract
The utility model relates to an interior-exterior circulation control device of a vehicle air conditioner. The device comprises a power supply, a CO2 concentration sensor, a CO concentration sensor, a microprocessor and a relay unit; the CO2 concentration sensor and the CO concentration sensor are arranged in a vehicle; the CO2 concentration sensor and the CO concentration sensor are connected with the power supply at the input ends, and are connected with the microprocessor at the output ends; and the microprocessor is connected with the vehicle air conditioner by the relay unit. Compared with the prior art, the interior-exterior circulation control device of the vehicle air conditioner has the advantages of detecting the air condition in the vehicle by adopting the sensors, controlling by the microprocessor, being capable of effectively switching the interior-exterior circulation of the vehicle air conditioner, facilitating improving the air quality in the vehicle, and being simple in operation, strong in actionability, simple in structure, small in occupied space after being mounted in the vehicle, and wide in application range.
Description
Technical field
The utility model relates to the Vehicle Electronic Control field, especially relates to a kind of air conditioning for automobiles inner-outer circulation control setup.
Background technology
Along with the development of auto-industry, the heating ventilation and air-conditioning on the automobile progressively becomes indispensable facility.Air conditioning for automobiles can provide comfortable environment inside car for the occupant, and can prevent or remove mist, frost or ice and snow on the Windshield.Yet, to the improper use of air-conditioning inner-outer circulation, not only easily make the driver get " air conditioner disease ", even more serious caused driver suffocates dead.
Modern automobile substantially all is the inner-outer circulation conversion of manually carrying out air conditioning for automobiles, has also formed thus some general knowledge.Such as, when traffic congestion, be adjusted to interior circulation; Use outer circulation during high speed; In order to reduce the driving engine energy consumption, be adjusted into interior circulation etc. when refrigeration or heating as far as possible.But manual regulation is not only loaded down with trivial details but also dangerous, unreliable.Although more senior automobile has been equipped full-automatic regulation air-conditioning, somewhat expensive.
The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of simple in structure, take up room air conditioning for automobiles inner-outer circulation control setup little, that precision is high, reliability is strong.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of air conditioning for automobiles inner-outer circulation control setup, this device comprises power supply, gas concentration lwevel sensor, carbon-monoxide concentration sensor, microprocessor and relay unit, described gas concentration lwevel sensor and carbon-monoxide concentration sensor all are located in the car, described gas concentration lwevel sensor all is connected with power supply with the input end of carbon-monoxide concentration sensor, the gas concentration lwevel sensor all is connected with microprocessor with the mouth of carbon-monoxide concentration sensor, and described microprocessor is connected with air conditioning for automobiles by relay unit.
Described relay unit comprises interior circulation relay and outer circulation relay, and described interior circulation relay and outer circulation relay are connected in parallel between microprocessor and the air conditioning for automobiles.
All connect by wire between each parts of this device.
Concentration and the carbon-monoxide concentration of carbon dioxide in described gas concentration lwevel sensor and the real-time inspection vehicle of carbon-monoxide concentration sensor, detection signal sends microprocessor to by wire, microprocessor compares detection signal and setting value, then inwardly circulate relay and outer circulation relay of microprocessor sends signal instruction, in real time the inner-outer circulation state of vehicles air-conditioning.When detection signal exceeds setting value, interior circulation relay disconnects, the outer circulation relay closes, this moment, air conditioning for automobiles was in the outer circulation mode of operation, replenished fresh air, when detection signal returns to normal value or after 10 minutes, the outer circulation relay disconnects, interior circulation relay closes, this moment, air conditioning for automobiles was in interior periodical duty state, reached good refrigeration or heating effect.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1, the utility model can switch the inner-outer circulation of air conditioning for automobiles effectively, is conducive to improve in-car air quality, and simple to operate, exploitativeness is strong.
2, the utility model adopts air regime in the sensor inspection vehicle, and implements control by microprocessor, and precision is high, and reliability is strong, is conducive to automobile and develops to complete electronic age.
3, the utility model is simple in structure, be installed in take up room in the car little.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is power supply, and 2 is wire, and 3 is the gas concentration lwevel sensor, and 4 is the carbon-monoxide concentration sensor, and 5 is microprocessor, and 6 is interior circulation relay, and 7 are the outer circulation relay, and 8 is air conditioning for automobiles.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
