ithe corresponding duration, n is the current number of times of the electric current that detects resistance R of flowing through.
Further, in another embodiment of the present invention, as shown in Figure 6, after calculating anode stub consumption, can also comprise:
S4, obtains anode stub surplus according to the initial current total amount of anode stub and anode stub consumption.
Wherein, the initial current total amount of anode stub can be thought and all consumes the electric current total amount of generation for anode stub, for example, can obtain anode stub surplus by calculating the initial current total amount of anode stub and the difference of consumption.
It should be noted that, in practice, engineer is advanced, and row data mapping is collected, for the definite anode stub being arranged in water heater, adopt the method for above-mentioned calculating anode stub consumption, the initial current total amount of antianode rod is measured, carry out the measurement collection of current sinking amount for the anode stub of the identical weight of specified mix, and sample optimization, data are stored in control module, in the time of the change of anode stub formula, the mapping that re-starts the initial current total amount of anode stub is collected, and is stored in the corresponding control module using.
Wherein, survey and draw collection by simulation different conditions, the initial current total amount that samples sample comparative test antianode rod more, data relatively have regularity, the data of collecting for the mapping of the magnitude of current meet rule substantially, in the time of different conditions, the anode stub of same recipe and identical weight, initial current total amount is basically identical.Reverse collected current total amount, the consumption of the corresponding anode stub of forward, thereby the data of the surplus anode stub surplus of judgement are substantially accurate, meet conformance law.
S5, antianode rod surplus shows.
Particularly, in one embodiment of the invention, anode stub surplus can be carried out to ratio conversion according to following calculating formula:
wherein,

alwaysfor the initial current total amount of anode stub, I
consumptionfor anode stub consumption.And then can carry out display case as shown 80%, 60%, 40%, 20% by the ratio value of display module antianode rod surplus, more simple and clear.
In addition, in another embodiment of the present invention, as shown in Figure 6, after obtaining anode stub surplus, above-mentioned water heater anode stub consumption amount estimating method can also comprise;
S6, compares anode stub surplus and default surplus threshold value.
For example compare ratio value and the default surplus threshold value of anode stub surplus.
S7, in the time that anode stub surplus is less than or equal to default surplus threshold value, carries out alarm.
Particularly, in the time that the ratio of anode stub surplus equals default surplus threshold value, carrying out alarm by control alarm module for example points out by sound, or present by display module, pass to display module and carry out display alarm to control display module, thus reminding user to replace anode stub in time.But the non-accuracy of data is collected in the mapping of the initial current total amount based on antianode rod, the method of alarm is taked fuzzyyer mode, for example, anode stub surplus shows precisely to 80% by display module, 60%, 40%, 20%, 10%, then report to the police with reminding user to replace anode stub by alarm module.
According to the water heater anode stub consumption amount estimating method of the embodiment of the present invention, flow through and detect electric current and the lasting Time Calculation anode stub consumption of electric current of resistance by basis, can automatically adapt to detect electric current according to the different behaviours in service of water heater, and then the reliable consumption that calculates exactly anode stub, computational methods are simple, are easy to apply.
In addition, show by antianode rod surplus, can make user understand at any time anode stub Expenditure Levels, and carry out and change preparing in advance of anode stub.In addition,, by carrying out alarm, can notify in time user to change anode stub.
