The specific embodiment
The present invention proposes a kind of water heater quick constant-temperature control method and device, it is applied to not have the water heater of discharge detector, and for the water heater that does not have the discharge detector, water heater often can't learn after startup how many water yields that will heat is, utilization of the present invention provides the gas flow of definite value to come water is heated, and by detecting the variation of water temperature in the unit interval, derive actual discharge relatively, and adjust the gas flow of supplying with water heater again after knowing actual discharge, and make water temperature can be tending towards the constant temperature of setting fast.
See also Fig. 3, it is the block diagram of one of preferred embodiment of the present invention.The water heater fast constant temperature control device of present embodiment includes a heater 21, a Temperature Detector 23, a gas flow controller 25 and a water temperature regulater 27, wherein heater 21 can heat the water that flows into water heater 20, and the required heat energy source of heater 21 heating is controlled by gas flow controller 25, and gas flow controller 25 can be controlled and input to the gas flow that heater 21 uses for heating.23 of Temperature Detectors are measured via the water temperature that heater 21 carries out after the heat treated at water.
And water temperature regulater 27 can be controlled the gas flow that gas flow controller 25 is exported to heater 21 according to the water temperature testing result of Temperature Detector 23.Water temperature regulater 27 has one first relation table 271 and one second relation table 273, corresponding relation between first relation table, 271 record gas flow, water temperature variable quantity and the discharges, this flow of invar the heat energy that relatively produces with actual flow into water heater 20 for the discharge of heating have certain relation between the water temperature variation of relative generation, present embodiment is recorded in first relation table 271 with this relation.273 of second relation tables are documented in the corresponding relation of the required preferable gas demand of thermostat temperature that will reach water temperature regulater 27 settings under the different discharges, and described preferable gas demand is meant the gas flow that can make water heater 20 reach thermostat temperature fast.
The control mode of water temperature regulater 27, after starting at water heater 20, controlling this gas flow controller 25 provides initial gas amount to use to heater 21, described initial gas amount is a definite value, and calculate the variation of water temperature in the unit interval, the temperature controller 27 that supplies water calculates actual discharge, and water temperature regulater 27 is after obtaining actual discharge, can judge further whether present initial gas flow is appropriate, and can adjust the gas flow that gas flow controller 25 is exported, and make water temperature can reach the constant temperature of setting fast.
See also Fig. 4, it is the flow chart of one of preferred embodiment of the present invention.Fig. 4 specifically implements according to the content shown in Fig. 3, includes the following step: open tap during beginning and make water heater 20 start (step S401); The initialization water heater 20 afterwards, to prepare to light master, the female fire (step S403) in the heater 21; Next the initial gas amount that provides definite value by gas flow controller 25 is for heater 21 heating (step S405) of burning; Calculate the water temperature variable quantity (step S407) in the unit interval after heater via 21 heat treated afterwards; And after learning the water temperature variable quantity, water temperature regulater 27 by first relation table 271 to calculate an actual discharge (step S409) that flows in the water heater 20; Same water temperature regulater 27 calculates an actual gas demand (step S411) by second relation table 273 after obtaining actual discharge; The gas amount that water temperature regulater 27 control gas flow controllers 25 are exported is an aforementioned actual gas demand (step S413); Next judge whether water temperature that water heater 20 is exported reaches the thermostat temperature (step S415) of setting; And when being judged as not, then jumping to step S407 and continue to carry out.
And in abovementioned steps S409, because this moment, water temperature regulater 27 obtained the gas flow that present water heater uses, and also know water temperature variable quantity in the unit interval, and gas flow the heat energy that relatively produces with actual flow into water heater 20 for the discharge of heating the water temperature variation of relative generation have certain relation, so water temperature regulater 27 can calculate real actual discharge according to the corresponding relation between first relation table 271 gas flow of putting down in writing, water temperature variable quantity and the discharge.
And in abovementioned steps S411, this moment, water temperature regulater 27 obtained the actual discharge that present water heater 20 uses, and water temperature regulater 27 can will reach under the different discharges that second relation table 273 is put down in writing the corresponding relation of the required gas demand of thermostat temperature and calculate pairing actual gas demand under this actual discharge relatively.
See also Fig. 5, it is the water heater temperature change curve measured according to present embodiment thermostatic control mode, gas with initial gas amount after water heater 20 starts comes water is heated, and by t1 time and t2 time relative water temperature a that records and b, to learn the water temperature variable quantity (b-a)/(t2-t1) in the unit interval scope, and knowing that the water temperature variable quantity can calculate actual discharge and actual gas demand in regular turn, and after time t3, initial gas amount made into actual gas demand.Can demonstrate the slope of curve before the t3 time less than the slope of curve of the t3 time after from Fig. 3, can reflect the time that use present embodiment thermostatic control mode can make water temperature reach constant temperature whereby effectively shortens.
Therefore according to the technological means of the fast constant temperature that present embodiment provided, for calculating actual discharge earlier, and the account form of actual discharge can be by known gas flow and water temperature variable quantity via calculating, and learn that actual discharge just can judge whether present gas flow is appropriate.Must reduce gas flow because if gas flow too much will make water temperature be higher than the thermostat temperature of setting and make water temperature approaching, so will waste the too much time towards thermostat temperature; Or because very few gas flow will make water temperature elongate near the time of thermostat temperature, and present embodiment can be by calculating actual gas demand in second relation table 273, this actual gas demand will allow the water temperature of water heater can reach thermostat temperature fast.
In sum, water heater quick constant-temperature control method provided by the present invention and device can utilize minimum hardware cost expenditure, and the water temperature that water heater is exported reaches the thermostat temperature of setting fast.
Yet; more than above-mentioned disclosed accompanying drawing, explanation; only be embodiments of the invention, those skilled in the art can carry out other all improvement according to above-mentioned explanation, and these improvement still do not break away from invention spirit of the present invention and the following scope of patent protection that is defined.
