Description
Technical field
The present invention relates to a kind of detect water-heater anode bar consume and report to the police indication method.
Background technology
For electric water heater, the consumption degree of anode bar, to consume speed be to affect water-heater work-ing life and user uses safe important hidden danger always.Magnesium rod is the one of anode bar, and magnesium rod uses as sacrificial anode in water-heater.Because the metal active of magnesium is higher than iron, in the situation that magnesium rod exposes with general steel plate simultaneously, first magnesium rod replaces steel plate corrosion to fall, thereby reaches the object of protection inner bag.How effectively to solve the problem that anode bar consumption brings, become the directly perceived important problem of electric water heater development.When magnesium rod approach exhaustion, it is particularly serious that the fouling of water-heater just becomes, once and fouling, the damage that water-heater is caused and the potential safety hazard of bringing are very serious.Dirt is hard as calculus, and the ability of transferring heat is very poor, only and irony or glass 1% less than, these dirts can be on the increase, can the many adverse consequencess of generation in the use of water-heater:
A makes the caloric receptivity deficiency of water, and the temperature of water is difficult to raise, the electricity charge of waste 30% left and right.Need 30 yuan of calculating by monthly heating up water, approximately 10 yuan are wasted.
B, because probe is wrapped up by incrustation scale, is difficult to detect the signal of water temperature and water level, easily causes mishandle.
The electrothermal tube heating efficiency of c boosting reduces.Because electrothermal tube is wrapped up by incrustation scale, dissipation of heat is not gone out, and causes interior heat too high, often blows nichrome wire or hardening cracks electric heating pipe box, easily causes danger, and has to often change.Anode bar also can make some corrosion component in water as the metal covering enrichment produce chemical corrosion reaction under dirt such as H+, OH-, Cl-, Mg2+, S2-.The result of corrosion is that localized metallic is damaged attenuate, and corrosion can reach and penetrate device steel plate, makes equipment leakage, the damaged degree even losing efficacy.Thereby maintenance of equipment expense is increased.When seriously corroded, can make equipment scrap in advance.
D internal diameter of the pipeline attenuates.Because the incrustation scale of tying in pipeline stops, make current not smooth.All above-mentioned faults, can make the use properties of water-heater have a greatly reduced quality, and cause great inconvenience and trouble to user.
The harm of e incrustation scale to HUMAN HEALTH.Tartar, periodontitis is often to be caused by incrustation scale.Can cause people desperately so far still without the preventible Legionella bacteria of vaccine, just conceal in incrustation scale, annual approximately 150,000 people die from this germ in the world, anode bar is also very serious for the injury of user's human body.
And at present, existing electric water heater cannot detect the anode bar consumption degree of water-heater reminding user timely effectively, accurately, cause shortening of electric water heater work-ing life, the safety in utilization of water-heater declines to a great extent.Also cannot be according to the difference condition of different areas water quality, judge the different time of water-heater anode bar consumption and need to change the time limit of anode bar.Because water quality can not get monitoring, cannot promptly and accurately judge by water surrounding quality, after causing water quality variation, anode bar consumption degree changes the impact that user is caused, and because of anode bar consumption, the serious and water quality polluted of water heater scaling is cooked and all brought impact having a bath, wash dish.
Because do not detect the method for water-heater water quality, existing electric water heater cannot detect according to the situation of water quality the anode bar consumption degree of electric water heater.The conductivity of water is an important indicator of water quality quality, and as GB regulation tap water resistivity 15 ℃ time should be greater than 1300 Ω cm, general pure water resistivity in the time of 25 ℃ can reach 18.3M Ω cmo
In general city tap-water, contain Ca
2+, Mg
2+etc. electron ion, if water quality is poor, contained number of ions is more, and ion can directly affect the elapsed time of anode bar, and the content of mineral substances difference of various places tap water is very large, is generally 100-450ppm.Therefore can determine water quality and anode bar consumption degree, the detection that consumes the time limit by the mode of the conductivity of test water.
From the present situation of current water quality detection, for the detection method of water quality in water-heater, how to accomplish that the real-time water quality that effectively detects water-heater embodies anode bar consumption degree and the consumption time limit of water-heater inside or one has problem to be solved.Current water quality inspection technique, does not relate to the detection to water-heater water, and is monitored the consumption situation of water-heater internal anode rod and will be reminded in time client by water quality detection, makes the consumption degree of client's antianode rod, replacing time limit accomplish very clear.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the invention provides a kind of detect water-heater anode bar consume and report to the police indication method.By the detection to water quality, judge water quality condition, and analyze the anode bar consumption degree of time limit that different quality situation lower water-heater internal anode rod consumes, different working life lower water-heater, and judge for the replacing of anode bar, for user provides comprehensive detection, be convenient to user and grasp the service condition of water-heater.

The timing time data of value, comparative result and the timing circuit of described micro-chip IC to the voltage signal of inputting, temperature compensation computing are stored.Temperature compensation computing described here is, for fear of water quality sensor temperature influence, the resistance detection of water is lost to accuracy.Definite says, temperature compensation is to make up water temperature over-high or the too low resistance value on water detects the impact bringing.The resistance value of general water detects carries out under the water temperature of 25 degree.The effect of temperature compensation is in the time that actual water temperature is spent higher than 25 degree or lower than 25, and resistance value is proofreaied and correct.Such as, when water temperature is 60 while spending, the signal of the resistance value that water quality sensor detects is 2K, so temperature compensation computing can by the water temperature that exceeds 25 degree offset 5%*2K corresponding to 35 degree from actual 2K numerical value, deduct, that is: 2K-2K*5%=1.9K.Same reason, if temperature lower than 25 degree, temperature compensation computing meeting adds certain offset on the basis of actual resistance.
In this programme, the signal value after compensation operation is corresponding one by one with time-count cycle, the time-count cycle of the corresponding different durations of signal value of different sizes.Form a tabular form, the signal value time-count cycles of corresponding different durations separately of different sizes, if the voltage of signal value is 1v, be 3 years corresponding time-count cycle, for 2v corresponding time-count cycle is 2 years, for 3v corresponding time-count cycle is 1 year.For the accuracy detecting, can be by numerical value and the more refinement of doing time-count cycle.
This programme is by detecting conductivity and the temperature of water and converting voltage signal to, by temperature compensation computing, the resistance value of water is proofreaied and correct, and start the time-count cycle of corresponding different durations according to the size of the value after temperature compensation computing, after completing time-count cycle, start warning indicator, for user provide water-heater anode bar consume situation.
In further preferred version provided by the invention: described micro-chip reads water quality signal and temperature compensation signal by the cycle, in steps d, micro-chip is accumulated stack to the signal value of each issue, and export the signal of accumulation stack to described warning indicator, show that with the form of histogram or cake chart accumulation stack measures by described warning indicator, carry out the anode bar accumulation Expenditure Levels of display water heater with this.
In this programme, the great advantage of this scheme is to detect in real time, dynamically the anode bar consumption degree of water-heater, show for user provides the monitoring of real-time anode bar consumption degree, make anode bar Expenditure Levels instantly of the real-time understanding water-heater of user and the degree of anode bar consumption that solution is provided.The inaccurate error problem of detection that the treatment process of accumulation stack can effectively avoid water heater environmental change to cause change of water quality to bring.As change of water quality in the process using, or water-heater changed the environment of installing and using, and will be real-time in the detection of ensuing this month embody, and embodies by histogram or cake chart.
In further preferred version provided by the invention: described micro-chip (IC) is in each cycle, repeatedly read water quality signal and temperature compensation signal, in steps d, micro-chip calculates mean value according to the multiple signal value in each cycle, and the mean value in each cycle is accumulated to stack, described micro-chip exports the signal of accumulation stack to described warning indicator, measured with the form demonstration accumulation stack of histogram or cake chart by described warning indicator, the anode bar that carrys out according to this display water heater consumes accumulation situation.In described micro-chip, be provided with benchmark value, in the time that described accumulation superposition value is more than or equal to described benchmark value, described micro-chip outputs control signals to described warning indicator, makes the histogram of described warning indicator or cake chart by red display, and/or sends sound and light alarm.In the time that described accumulation superposition value is more than or equal to described benchmark value, described micro-chip IC zero clearing, carries out the accumulation superposition of next round.
The improvements of this programme are, can detect more accurately and avoid the detection error that water environmental change brings, micro-chip repeatedly reads water quality signal in each cycle, and average, then accumulate stack with the mean value in each cycle, the cycle can be 1 month, within the cycle of 1 month, can divide and read water quality signal 4 times, make like this dynamic monitoring more accurate, avoid water quality environment to change the detection error of bringing, make anode bar consumption monitoring more accurate.Can, according to the situation of various places, carry out the adjustment cycle time, 1 month or 1 season or half a year are one-period.Cycle is shorter, and the error that change of water quality is caused is just less, and the monitoring accuracy that water quality detection and anode bar consume is just higher.
The present invention also provides another kind of scheme, in steps d, described micro-chip (IC) compares the signal value after compensation operation and default benchmark value: if the value is relatively greater than a, timing module started for the first time-count cycle, and the timing time of described the first time-count cycle is J; Or value is relatively more than or equal to b and is less than or equal to a, timing module started for the second time-count cycle, and the timing time of described the second time-count cycle is K; Or value is relatively less than b, timing module started for the 3rd time-count cycle, the timing time of described the 3rd time-count cycle is L, described J>K>L, after completing, described the first time-count cycle or the second time-count cycle or timing the 3rd time-count cycle output control signals to described warning indicator startup work, the anode bar Expenditure Levels of reminding user water-heater by the output terminal of described micro-chip.
In this programme, if the magnitude of voltage that described micro-chip (IC) compares rear signal to the signal value after compensation operation and default benchmark value is at below 20% of micro-chip (IC) service voltage, timing module started for the first time-count cycle, the timing time of described the first time-count cycle
For J; Or relatively after signal magnitude of voltage micro-chip (IC) service voltage 20% to 40% between, timing module started for the second time-count cycle, the timing time of described the second time-count cycle is K; Or the magnitude of voltage of signal is at the more than 40% of micro-chip (IC) service voltage relatively, timing module started for the 3rd time-count cycle, and the timing time of described the 3rd time-count cycle is L.
The service voltage of described micro-chip (IC) is 5V, in step e: the signal relatively, if its voltage below 1V, timing module started for the first time-count cycle, the timing time of described the first time-count cycle is between 2 years to 3 years; Or signal relatively, if its voltage between 1V to 2V, timing module started for the second time-count cycle, the timing time of described the second time-count cycle is between 1 year to 2 years; Or signal relatively, if its voltage more than 2V, timing module started for the 3rd time-count cycle, the timing time of described the 3rd time-count cycle is in 1 year.
As shown in Figure 2, described signal pre-processing circuit comprises water quality detection circuit, temperature-compensation circuit, described water quality detection circuit is detected the resistance signal of water and is changed into voltage signal by water quality sensor R and inputs to described signaling conversion circuit, and described temperature-compensation circuit is detected the temperature signal of water and changed into voltage signal by described temperature sensor RT and inputs to described signaling conversion circuit.
Described testing circuit also comprises the first resistance R 1, one end ground connection of described the first resistance R 1, one end of described water quality sensor R is connected with Vcc, and the other end of the other end of described the first resistance R 1 and described water quality sensor R together accesses No. 1 input port of described micro-chip IC.Described temperature-compensation circuit also comprises the second resistance R 2 and the first capacitor C 1, described the second resistance R 2 and described the first capacitor C 1 parallel connection, and the one end after parallel connection is connected with Vcc, No. 2 input ports of the described micro-chip IC of the common access in one end of the other end and described temperature sensor RT, the other end ground connection of described temperature sensor RT.Described alert circuit comprises light-emitting diode display, and described light-emitting diode display is connected with No. 5 output ports for No. 3, No. 4 with described micro-chip IC's.
In the time that water quality is good, the resistance of water quality sensor R is larger, and Vcc is by the dividing potential drop of water quality sensor R and the first resistance R 1, lower at the voltage of micro-chip IC1 input port; When water quality bad time, the resistance of water quality sensor R is less, and Vcc is by the dividing potential drop of water quality sensor R and the first resistance R 1, higher at the voltage of No. 1 input port of micro-chip IC.Be the lower voltage of good water quality correspondence, the poor higher voltage of water quality correspondence.In the time that water temperature is higher, the resistance of temperature sensor RT is less, and Vcc is by the dividing potential drop of the second resistance R 2 and temperature sensor RT, less at the voltage of No. 2 input ports of micro-chip IC; In the time that water temperature is lower, the resistance of temperature sensor RT is larger, and Vcc is by the dividing potential drop of the second resistance R 2 and temperature sensor RT, larger at the voltage of No. 2 end inbound ports of micro-chip IC.The first capacitor C 1 is done filtering.The higher lower voltage of temperature correspondence.Analog to digital conversion circuit in micro-chip IC carries out analog to digital conversion to the signal of No. 1 input port and No. 2 input port inputs, after conversion, carry out temperature compensation computing by temperature compensation module, value after temperature compensation computing and the benchmark value of setting are compared by comparison module, start corresponding timing circuit timing according to different comparative results, after timing completes, in startup alert circuit, corresponding led pipe is lighted, the scaling degree of the current water-heater of reminding user.
