The electronic control unit is further connected with the timer, the memorizer and the alarm device. The automatic defrosting and demisting device of the automobile can be used to judge whether a front windshield needs to be defrosted and demisted, when the front windshield needs to be defrosted and demisted, the automatic defrosting and demisting device of the automobile can automatically turn on the defrosting and demisting unit, a driver does not need to operate the defrosting and demisting unit manually, distraction of the driver is avoided, and therefore driving safety of the driver is improved.
Description
Technical field
The utility model relates to the car electrics field, refers in particular to a kind of car automatic defrosting demister.
Background technology
Winter is because the outer temperature of car is lower, the inside and outside temperature contrast of car can cause Windshield water smoke often to occur, behind the chaufeur start the engine, water smoke can't leave voluntarily, so when driving, need chaufeur manually to open the effect that the defrosting-defogging function reaches defrosting-defogging, but this will make the chaufeur dispersion attention, might cause traffic accident when running into accident when the operation of chaufeur in the function of opening defrosting-defogging.China Patent Publication No. CN201872719U, in open day on June 22nd, 2011, name is called in the utility model patent of " a kind of automatic indoor demisting device for automobile " and discloses a kind of automatic indoor demisting device, device and ignition lock of shared motor; Humidity sensor is contained in the humidity of detection glass on glass with in good time demist, sensor signal is passed to the demist signal generator, utilize impulse singla automatic control circuit break-make, make the heating of demist hot line remove mist on glass, be in the driving process at automobile, device is automatic defrosting according to circumstances, but this device does not have the set temperature sensor, only relies on humidity sensor need to judge whether the defrosting-defogging sometimes can be inaccurate.
The utility model content
The purpose of this utility model is when overcoming the front windshield of automobile in the prior art such as need defrosting-defogging, chaufeur needs M/C to open the defrosting-defogging function, produce easily the defective of potential safety hazard, a kind of car automatic defrosting demister is provided, whether the front windshield of device energy automatic decision automobile needs defrosting-defogging, need not chaufeur and manually operates.
The purpose of this utility model is to be achieved by following technical proposals:
A kind of car automatic defrosting demister, comprise electronic control unit and defrosting-defogging device, electronic control unit connects the defrosting-defogging device, is equipped with temperature sensor and humidity sensor outside Che Nei and car, and temperature sensor and humidity sensor be the connecting electronic control unit simultaneously.Behind engine starting, the temperature and humidity that temperature sensor and humidity sensor inspection vehicle are inside and outside, after humidity or heal differential are greater than preset value, judge that there is water smoke in Windshield or is about to produce water smoke, after electronic control unit receives signal, send a signal to the defrosting-defogging device, open the defrosting-defogging function.Whole process need not the chaufeur intervention.
As a kind of preferred version, car automatic defrosting demister also comprises time meter, time meter connecting electronic control unit.After the defrosting-defogging device was started working, time meter was started working, and after through the time of setting, time meter sends a signal to electronic control unit, and electronic control unit sends a signal to the defrosting-defogging device, and the defrosting-defogging device quits work.
As a kind of preferred version, car automatic defrosting demister also comprises memory device, memory device connecting electronic control unit.The data such as the number of times that memory device record defrosting-defogging device is opened, time, information can feed back to chaufeur by front gauge panel, allows chaufeur understand detailed information for your guidance.
As a kind of preferred version, car automatic defrosting demister also comprises annunciator, annunciator connecting electronic control unit.When timer record behind the certain hour, the defrosting-defogging device quits work, at this moment, humidity changing value in the car that humidity sensor detects less than preset value after, electronic control unit judges that the defrosting-defogging device lost efficacy, this moment, electronic control unit sent a signal to annunciator, and alarm equipment alarm reminding driver defrosting-defogging device lost efficacy.
As a kind of preferred version, annunciator is buzzer siren.
The beneficial effects of the utility model are, device can judge whether front windshield needs defrosting-defogging, and when needing the defrosting-defogging timer can automatically open the defrosting-defogging device, need not chaufeur and manually operate, avoid chaufeur to take sb's mind off sth, improved the safety that chaufeur is driven.
Description of drawings
Fig. 1 is a kind of circuit catenation principle figure of the present utility model.
Fig. 2 is a kind of diagram of circuit that the utility model is opened the demist defogger automatically.
Wherein: 1, electronic control unit, 2, the defrosting-defogging device, 3, humidity sensor, 4, temperature sensor, 5, time meter, 6, memory device, 7, annunciator.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment: a kind of car automatic defrosting of the utility model demister, its circuit theory connection diagram comprise electronic control unit 1, defrosting-defogging device 2, humidity sensor 3, temperature sensor 4, time meter 5, memory device 6 and annunciator 7 as shown in Figure 1.Temperature sensor 4 and humidity sensor 3 connecting electronic control units 1, electronic control unit 1 connects defrosting-defogging device 2.Electronic control unit 1 is gone back connection timer 5, memory device 6 and annunciator 7.Annunciator 7 is buzzer siren 7.The diagram of circuit that car automatic defrosting demister is opened automatically as shown in Figure 2, behind vehicle launch, temperature sensor 4 and humidity sensor 3 are differentiated respectively car inside and outside heal differential and psychrometric difference, if heal differential or psychrometric difference are during greater than preset value, electronic control unit 1 judges that there is water smoke in Windshield or is about to exist water smoke, and electronic control unit 1 sends a signal to defrosting-defogging device 2 and opens the defrosting-defogging function; If heal differential and psychrometric difference all are less than or equal to preset value, then be judged as and do not produce water smoke, device will not operate, until after a period of time, temperature sensor 4 and humidity sensor 3 again image data are judged again.After defrosting-defogging device 2 was started working, time meter 5 was started working, and after through the time of setting, time meter 5 sends a signal to electronic control unit 1, and electronic control unit 1 sends a signal to defrosting-defogging device 2, and defrosting-defogging device 2 quits work.After this, the data such as the number of times that memory device 6 record defrosting-defogging devices 2 are opened, time, the information after the collection can feed back to chaufeur by front gauge panel, allows chaufeur understand detailed information for your guidance.When defrosting-defogging device 2 is opened by stopping after a while, humidity changing value in the car that humidity sensor 3 detects less than preset value after, electronic control unit 1 judges that defrosting-defogging device 2 lost efficacy, this moment, electronic control unit 1 sent a signal to annunciator 7, and annunciator 7 warning reminding chaufeur defrosting-defogging devices 2 lost efficacy.
