Δ time: used time when rising 1 unit temperature.
On section: heat temperature raising curved section during closed heating unit power.
Off section: temperature lowering curve section when disconnecting heating unit power.
When temperature during less than Tz, the heating unit power closure is carried out heat temperature raising, in this temperature curve section, obtains Δ time according to said method;
When temperature arrives Tz, close heating unit power, utilize the waste heat heat temperature raising, the stand-by period is (t2-t1).If temperature reaches Tset in the stand-by period, then enter other duty; If time is up t2, temperature does not also reach desired value, then sends control signal control heater and carries out work, and so that water temperature is heated up, be (t3-t2) heat time heating time, can draw from following formula:
(t3-t2)＝[(Tset-Tn)×Δtime]，
Heater quit work after time is up;
As long as temperature reaches Tset, enter next duty, otherwise utilize the waste heat heat temperature raising in heat time heating time, the stand-by period is (t4-t3), if temperature reaches Tset in the stand-by period, enters next duty;
If the time reaches the temperature T set that the t4 temperature never reaches setting, then the closed always later on power supply heater heat temperature raising of t4 reaches Tset up to coolant-temperature gage, enters next duty.
In the ordinary course of things, when heating curve proceeds to t2 or t3, will reach the temperature T set of setting; Only under the situation that detection Δ time mistake occurs, just can proceed to t4 and reach state later on.
