Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of demister, particularly a kind of windshield demister.
Background technology
Under autumn and winter, situation such as rain, the Windshield inside face of automobile is tied mist easily and is influenced the navigating mate visual field, and then causes traffic accident, causes very big loss or injury to the party concerned, also brings very big problem to traffic control.At present, the method for demist mainly contains: suitably open vehicle window, make and reduce the car internal-external temperature difference by the car interior-exterior circulating air, to eliminate the fog that the vehicle window inside face is condensed; Perhaps use towel or paper handkerchief wiping vehicle window inside face to carry out demist; Or open air conditioning for automobiles, carry out demist through regulating vehicle interior temperature.
Though above-mentioned the whole bag of tricks can carry out demist effectively, but in vehicle traveling process, these methods have been disperseed the attention of navigating mate, have brought potential safety hazard to a certain degree.Temperature is terribly cold, awfully hot outside running into car, and when environment was abominable, it obviously was worthless opening the method that vehicle window carries out demist; Adopting towel or paper handkerchief wiping vehicle window inside face is avoiding greatly of safe driving; Adopting air-conditioning air-supply demist is the main means of present automobile demist.
The notification number of authorizing on May 4th, 2005 like State Intellectual Property Office of the People's Republic of China is the patent documentation of CN 2696891Y; Name is called " the automatic anti-smog device of automobile "; Through being arranged on the temperature sensor in the vehicle window and being arranged on ambient signal in the humidity sensor inspection vehicle in the car; Then information is sent to the microprocessor of preset critical temperature and humidity value, pass through microprocessor will receive after information and the preset value contrast processing Control of Automobile air-conditioning the demister switch open or close defrosting function.The weak point of this scheme: behind the opening automobile air-conditioning; Need Control of Automobile air-conditioner temperature manually; Thereby can not accurately select the temperature required demist of carrying out, if the temperature of selecting is low excessively, make that the temperature in the car produces contradiction with the required proper temperature of the personnel of riding; Cause the personnel that ride to feel under the weather, influenced the traveling comfort of riding; If the temperature of selecting is too high, then accelerate water in air and divide atomizing, make visiblity lower, to disagree with opening the original intention that air-conditioning carries out demist, and manually control air-conditioner temperature demist meeting influence and drive, safety is not high.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of air conditioning for automobiles that can make and has selected suitable temperature to carry out the windshield demister of demist automatically.
The purpose of the utility model can realize through following technical proposal: a kind of windshield demister; Comprise power supply, switch, indicator lamp, master controller, be arranged on internal surface of car windscreen the vehicle window temperature sensor, be arranged on the humidity sensor in the car; Described power supply, switch, indicator lamp, master controller are connected successively with air conditioning for automobiles and are formed the loop; Described vehicle window temperature sensor all is connected with master controller with described humidity sensor; It is characterized in that described windshield demister also comprises and is arranged on the air conditioning for automobiles and the air charge temperature sensor that is connected with master controller.
After navigating mate is pressed this windshield of switch open demister; Be connected vehicle window temperature sensor and humidity sensor on the master controller and begin to detect humidity in temperature and the car of a side in the Windshield car respectively; Send testing result then and give master controller; Master controller receives the signal that vehicle window temperature sensor and humidity sensor send, through sending signal after the calculation process to air conditioning for automobiles, the Control of Automobile air-conditioning to air-conditioning air inlet regulate; Simultaneously; Be positioned at the temperature that air charge temperature sensor on the air conditioning for automobiles begins to detect the air-conditioning air inlet; And the result sent to master controller, master controller is through receiving the feedback signal of vehicle window temperature sensor, humidity sensor and air charge temperature sensor, handles the back once more and sends new control signal and give air conditioning for automobiles; Thereby carry out real-time monitoring air-conditioning intake temperature and suction quantity, finish until demist.
In above-mentioned a kind of windshield demister, described air charge temperature sensor is arranged on the air outlet of air conditioning for automobiles, is used to detect the temperature of air-conditioning air inlet.
In above-mentioned a kind of windshield demister, described air conditioning for automobiles also comprises being arranged on and is used for the electric heater that air inlet is heated to air-conditioning in the air-conditioner host.Electric heater is behind the control signal that receives air conditioning for automobiles, and air inlet is heated to air-conditioning.
In above-mentioned a kind of windshield demister, described switch and described indicator lamp are integrated on the control panel of described air conditioning for automobiles.Through making that the integrated operation beautiful interface is succinct on the control panel that switch and indicator lamp is integrated in air conditioning for automobiles, and make switch and indicator lamp be in the position that navigating mate is familiar with, operation, observe convenient.
In above-mentioned a kind of windshield demister, described master controller is the Engine ECU of automobile.In the program of this Engine ECU, be preset with temperature and humidity value curve and corresponding control signal; After Engine ECU receives the signal that each sensor sends, carry out comprehensive treatment and with program in preset value relatively, select to send appropriate control signals Control of Automobile air-conditioning then.
In above-mentioned a kind of windshield demister, described power supply is an on-vehicle battery.Adopt on-vehicle battery as power supply, make this windshield demister need not to establish in addition power supply, simple in structure, arrangement convenience.
Compared with prior art; This windshield demister can be regulated electric heater through main controller controls and air heating is blown into behind the proper temperature carries out demist in the car; Can effectively avoid carrying out the phenomenon generation that demist causes the occupant to do not feel like oneself, increase personnel's comfort by bus by bus because of in car, being blown into cold wind; And this windshield demister adopts one-touch mode, when needs are opened this windshield demister, presses switch and can automatically perform defrosting function, and is convenient and reliable, makes vehicle drive have more comfort feature and safety.
