Background technology
At present, along with expanding economy, automobile becomes people's instrument used in everyday, but the people that drove car can run into a difficult problem: in the winter time; Because outside air temperature is lower, early morning, the Windshield of automobile can produce one deck frost, if untimely removal; Can disturb normal driving, and automobile in the process of moving, because the inside and outside temperature difference in compartment; Windshield also can produce fog, can influence the safety traffic of chaufeur equally, has bigger potential safety hazard; Gently then make easily comfortable driving of chaufeur, heavy then possibly cause bigger traffic accident, cause the heavy losses of property.So all possess in the general present automobile air-conditioning defrost function arranged,, also have some problems though solved the problem of defrosting; When just started car severe winter in the north like automobile; Because ECT Engine Coolant Temperature is low, this makes defrosting speed very slow, uses to the user and has brought puzzlement.Like publication number is CN201872723U, and name is called a kind of middle utility model patent of automobile defrosting device, and its structure comprises casing; The casing internal fixation has blower fan and radiator-water box, and blower fan connects a controller, and radiator-water box links to each other with temperature booster or engine cooling and circulating system; And casing is provided with a plurality of air outlets, and air outlet is provided with blast connection, connects defrosting air pipe on the blast connection; Defrosting air pipe and universal air outlet are connected, and the automobile defrosting device will pass through radiator-water box from the high temperature coolant of temperature booster or engine cooling and circulating system, and the air themperature in the casing is raise; Evenly be blown into windshield through blower fan, defrost or demist.But just there is above-mentioned shortcoming in the defogger of this patent: when automobile had just started car in northern severe winter, the driving engine heat was lower, makes that radiator-water box intrinsic motivation water temperature is low, and the interior air themperature of casing raises slower, and this makes defrosting speed very slow.
Summary of the invention
When the utility model has mainly solved general automobile just started car severe winter in the north,, make the problem that defrosting speed is very slow, the intelligent electric heating system that provides that a kind of firing rate is fast, the air conditioning for automobiles of energy savings defrosts because ECT Engine Coolant Temperature is low.
The utility model solves the technical scheme that its technical matters adopted: a kind of air-conditioner defrosting intelligence electric heating system; Comprise air-conditioner controller; Also include auxiliary electric heater unit; Said auxiliary electric heater unit comprises the first sensor that is used for ambient temperature in the inspection vehicle, the electrical auxiliary heater that is used to detect second sensor of air-conditioning warm braw core body temperature and is installed in the air-conditioner defrosting air outlet; The said first sensor and second sensor are connected respectively to the air-conditioner controller input end, and said electric heater is connected the air-conditioner controller mouth.The utility model has increased auxiliary electric heater unit on original air conditioner defrosting system; This auxiliary electric heater unit can open or close electrical auxiliary heater according to the temperature conditions of heater unit core body and environment; Effectively like this shortened the air heating time; Solved present automobile when just started northern severe winter, had the slow problem that defrosts because of ECT Engine Coolant Temperature is low, the operation scheme of intelligence has been practiced thrift the energy greatly simultaneously.
As a kind of preferred version; Said air-conditioner controller includes incoming signal processing unit, micro-computer unit and output signal processing unit; The incoming signal processing unit is connected to the micro-computer unit input end; The micro-computer unit mouth is connected with the output signal processing unit, and the said first sensor and second sensor are connected on the incoming signal processing unit input end, and said electrical auxiliary heater is connected on the output signal processing unit mouth.The incoming signal processing unit is used to receive the signal of two sensors, and with sending micro-computer unit after the signal conditioning to.Micro-computer unit judges sensor signal, if ambient temperature, is sent open command and given the output signal processing unit when all low with warm braw core body temperature, sends to electrical auxiliary heater by the output signal processing unit again, controls and opens electrical auxiliary heater; When if ambient temperature and warm braw core body temperature are higher than recommended value, send shutdown command and give the output signal processing unit, send to electrical auxiliary heater by the output signal processing unit again, electrical auxiliary heater is closed in control; Played Based Intelligent Control auxiliary electric heater unit effect, actv. has been practiced thrift electric energy.
As a kind of preferred version, said electrical auxiliary heater is the PTC electric heater.The PTC electric heater is made up of the PTC sensitive to heat, and when surpassing certain temperature, its resistance value is increasing of step evolution with the rising of temperature, and time of heat is short, and is very easy to use.
As a kind of preferred version, said electrical auxiliary heater includes the warm-up control switch, and electrical auxiliary heater links to each other with air-conditioner controller through the warm-up control switch.The warm-up control switch is used to open and close electrical auxiliary heater, and it is controlled by air-conditioner controller.
The utility model has the advantages that: 1. increased auxiliary electric heater unit, can be in the temperature of heater unit core body and environment assistant heating air under the not high situation, effectively like this shortened the air heating time, improved defrosting speed; 2. the operation scheme of auxiliary electric heater unit intelligence has been practiced thrift the energy greatly.
