Description
Technical field
The present invention relates to a kind of automobile air-conditioning filter changes alarm set, adopts the automotive air-conditioning system of this alarm set and adopt the automobile of this automotive air-conditioning system.
Background technology
Automobile is as a kind of modern means of communication, inseparable with people's life.According to statistics, the annual time that modern city people spends in automobile is 730 hours, and therefore level of comfort and the health status tool of the air quality in automobile to passenger has a great impact.
Automotive air-conditioning system is the abbreviation of automobile air-condition system, adopts the method for artificial cooling and heating, regulates the parameter indexs such as temperature in car, humidity, air-flow velocity, cleanliness, thereby creates the environment inside car of fresh and comfortable for people.Owing to conventionally containing impurity in general air, it comprises finely ground particles, pollen, bacterium, industrial gaseous waste and dust etc., thereby in automotive air-conditioning system, dispose air-conditioning filter cleaner, in air-conditioning filter cleaner, contain filter core, the Main Function of filter core is, filter the air that enters interior from the external world, prevent that thereby above-mentioned impurity from entering a/c system and entering compartment, the cleanliness of air in car is improved, give simultaneously the indoor fresh air that provides is provided, good air ambient is provided to passenger in car, guarantee occupant's is healthy.
At present, in air conditioning for automobiles, air-conditioning filter cleaner filter core is generally arranged near the admission port of automotive air-conditioning system, the namely front side of blowing engine in whole airflow field, for filtered air to ensure the air quality in passenger compartment.No matter the mode of operation of blowing engine is new wind pattern (air from outside to inside) or interior circulation pattern (air is from interior to interior), the air of blowing engine wind outlet all needs to filter by air-conditioning filter cleaner.When a/c system used after a period of time, it regulates efficiency to reduce, now should consider to change air-conditioning filter cleaner, it is more simply and cheaply the filter core of only changing in air-conditioning filter cleaner, easy for describing, will change air-conditioning filter cleaner and only change all unified replacing air-conditioning filter cleaners that is called of filter core in air-conditioning filter cleaner herein.
In the prior art, the general time-based maintenance mode that adopts is changed air-conditioning filter cleaner, determine whether changing air-conditioning filter cleaner according to vehicle driving mileage or running time, for reminding user is changed air-conditioning filter cleaner in time, some middle-and-high-ranking configuration of automobiles have " replacing air-conditioning filter cleaner " automatic alarm set.
Application number is in the Chinese patent of 200810201863.X, to disclose a kind of " reminding device for replacing air-conditioning filter cleaner ", this device is by the add up work-hours of unit accumulative total air-conditioning filter cleaner of time, by this work-hours compared with preset reminder time, by Tip element to user's output " replacing air-conditioning filter cleaner " information.In addition, application number is in 200920070607.1 Chinese patent, to disclose a kind of " reminding device for replacing air-conditioning filter cleaner ", this device is by the add up travelled distance of unit accumulative total vehicle of mileage, by this travelled distance compared with preset prompting mileage, by Tip element to user's output " replacing air-conditioning filter cleaner " information.Above-mentioned two patents are all by comparing or remind mileage and travelled distance to compare preset reminder time and running time, point out user to change air-conditioning filter cleaner, provide reference timely for user changes air-conditioning filter cleaner, but the substitute mode that these two kinds of alarm sets adopt still belongs to time-based maintenance substitute mode.
In real life, owing to there is very big-difference in the environment for use of different vehicle and the Occupation coefficient of automotive air-conditioning system, make the extent of deterioration of air-conditioning filter cleaner in different vehicle also have very big-difference, by existing time-based maintenance mode or according to default travelled distance or running time reminding user to replace air-conditioning filter cleaner, often exist to change and judge inaccurate situation, often cause too early or spend evening and change air-conditioning filter cleaner, if changed too early, easily cause the wasting of resources, user's the car cost of using is increased; Spend evening and change the regulating effect that can affect a/c system, cause in-car air quality to decline, reduce the comfort level that user takes, bring healthy hidden danger.Therefore, change the mode that air-conditioning filter cleaner is changed of available technology adopting, there is positive meaning for the needs that meet market user.
Summary of the invention
Technical matters to be solved by this invention is the replacing above shortcomings for air-conditioning filter cleaner in prior art, and providing a kind of can change alarm set and adopt the automotive air-conditioning system of this alarm set and adopt the automobile of this automotive air-conditioning system for user provides the automobile air-conditioning filter of changing air-conditioning filter cleaner information to change based reminding method, automobile air-conditioning filter accurately, timely.
While operation under AD HOC (such as, refrigeration or heating mode etc. under economic model, fitness mode, uniform temperature) due to automotive air-conditioning system, when in the situation of other consumer current stabilizations in automobile, the working current value of blowing engine is a relatively-stationary value.Research shows, when motoring condition one timing, the pass of the working current of blowing engine and air-conditioning filter cleaner clean-up performance is: air-conditioning filter cleaner clean-up performance is less, the static pressure of blowing engine is larger, and air quantity is less, and power is less, because operational voltage value in blowing engine is generally definite value, therefore blower power is less, its working current value is less, and the relation between blower air quantity, static pressure Ps and electric current I three as shown in Figure 1.Hence one can see that, regularly detects by the working current to blowing engine, for example, detect once every a few minutes, can accurately judge the clean-up performance of air-conditioning filter cleaner according to the size of working current value.In the case of the general replacement standard that need to change according to air-conditioning filter cleaner judges, for meeting an air-conditioning filter cleaner of general replacement standard, in the time that it uses in automotive air-conditioning system, can detect obtain blowing engine the working current value of different operational tapses (multiple different adjustment gears that wherein blowing engine has be the mode of operation different according to blowing engine or under certain mode of operation its watt level distinguish), the working current of the blowing engine that detection obtains must be less than the running current of its corresponding blowing engine at this operational taps.Because blowing engine is to change among a small circle at one at the running current of each different operational tapses according to the different situations in reality, thereby can set a current damping allowed band value, become more rationally with more accurate to make to change judgement.Certainly,, due to the standard that different users may exist different replacing air-conditioning filter cleaners, also can set current damping allowed band value in conjunction with user's actual conditions.
