Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1, the method for controlling temperature of a water heater provided in this embodiment includes the following steps:
s1, acquiring a set temperature;
s2, judging whether the water outlet flow of the water heater exceeds a preset value or not; if yes, go to step S3; if not, go to step S6;
s3, judging whether the water outlet flow of the water heater fluctuates or not; if yes, go to step S4; if not, go to step S6;
s4, adjusting the opening of the gas proportional valve according to the set temperature;
s5, controlling the opening degree of the water quantity regulating valve to be reduced;
and S6, controlling the opening of the gas proportional valve according to the water outlet temperature of the water heater so as to enable the water outlet temperature to reach the set temperature.
Specifically, when the water outlet flow of the water heater is large in a period of time and exceeds a preset value (such as 7 liters/minute), the problem of unstable outlet water temperature due to fluctuation of the outlet water flow may occur. For example, the minimum water outlet flow of the water heater is 4 liters/minute, the maximum water outlet flow is 11.5 liters/minute, the difference reaches 7.5 liters/minute, the fluctuation range of the water outlet flow is large, and the water outlet temperature is unstable.
And step S5, controlling the water inlet flow of the water heater by controlling the opening degree of the water quantity regulating valve to be reduced, and further controlling the fluctuation range of the water outlet flow, thereby realizing the control of the water outlet temperature. For example, the opening of the water quantity regulating valve is controlled to be reduced, the maximum water outlet flow is limited to 6.5 liters/minute, and under the condition that the minimum water outlet flow is 4 liters/minute, the difference value of the water outlet flow is 2.5 liters/minute, the fluctuation range is small, and therefore the water outlet temperature is stable.
Since the flow rate of the discharged water is rapidly changed at the moment of switching the opening degree of the water amount adjusting valve, and there is a possibility that the temperature of the discharged water largely fluctuates, the opening degree of the gas proportional valve is adjusted according to the set temperature before the opening degree of the water amount adjusting valve is controlled to be decreased in step S4. The opening of the gas proportional valve after the adjustment can directly influence the temperature response of the water heater at the moment of switching the opening of the water quantity adjusting valve, and if the adjustment is improper, great temperature fluctuation can be generated.
After the opening degree of the water volume adjusting valve is switched, step S6 further adjusts the opening degree of the gas proportional valve according to whether the current leaving water temperature reaches the set temperature, so that the leaving water temperature reaches the set temperature.
According to the temperature control method of the water heater provided by the embodiment, the fluctuation range of the water outlet flow of the water heater is reduced by controlling the opening of the water quantity regulating valve; meanwhile, the opening of the fuel gas proportional valve is adjusted according to the set temperature, so that the phenomenon that the instantaneous temperature change of the water quantity adjusting valve is too large is avoided; therefore, the stability of the temperature of the outlet water can be maintained, and the constant temperature performance of the water heater is improved.
Example 2
On the basis of embodiment 1, the present embodiment provides a temperature control method for a water heater.
In one implementation, referring to fig. 2, step S4 includes:
s401, judging whether the set temperature is greater than a first preset temperature or not; if yes, go to step S402; if not, go to step S403;
s402, adjusting the opening degree of the corresponding gas proportional valve according to the first preset temperature;
s403, judging whether the set temperature is higher than a second preset temperature or not, wherein the second preset temperature is lower than the first preset temperature; if yes, go to step S404; if not, go to step S5;
and S404, if so, adjusting the opening degree of the corresponding gas proportional valve according to the second preset temperature.
Specifically, the opening degree of the corresponding gas proportional valve can be adjusted according to different set temperatures, so that the outlet water temperature of the water heater cannot be changed greatly at the moment of switching the opening degree of the water quantity adjusting valve.
For example, the first preset temperature is 60 ℃ and the second preset temperature is 50 ℃. First, it is determined whether the set temperature is greater than 60 ℃, and if so, the opening degree of the gas proportional valve is adjusted to 40%, and then the step of controlling the opening degree of the water quantity adjusting valve to decrease in step S5 is performed. If the set temperature is not more than 60 ℃, further judging whether the set temperature is more than 50 ℃, if so, adjusting the opening of the gas proportional valve to 50%, and then executing the step of controlling the opening of the water quantity regulating valve to reduce in the step S5; if the set temperature is not greater than 50 ℃, step S5 is directly executed to control the opening of the water quantity regulating valve to decrease.
It should be noted that, besides the first preset temperature and the second preset temperature, other temperature gears can be divided according to actual requirements, so that the opening degree of the gas proportional valve is adjusted more accurately, and the constant temperature performance of the water heater is improved.
In one implementation, step S2 includes:
s201, acquiring the water outlet flow of the water heater in a preset time period;
s202, judging whether the average water outlet flow in the preset time period exceeds a preset value or not; if yes, go to step S3; if not, step S6 is executed.
For example, the water flow rate of the water heater may be measured 200 times within 10 seconds and the average water flow rate is calculated, and if the average water flow rate exceeds a preset value of 7 l/min, the step S3 needs to be executed to determine whether the water flow rate of the water heater fluctuates.
In one implementation, step S3 includes:
s301, calculating a water flow difference value according to the maximum water outlet flow and the minimum water outlet flow of the water heater in the preset time period;
s302, judging whether the effluent flow difference value is larger than a preset difference value or not; if yes, go to step S303; if not, executing step S304;
s303, determining that the water outlet flow of the water heater fluctuates; and performs step S4;
s304, determining that the water outlet flow of the water heater does not fluctuate; and performs step S6.
For example, if the difference between the maximum outlet flow and the minimum outlet flow of the water heater in 10 seconds is greater than a preset difference of 3 liters/minute, it is determined that the outlet flow of the water heater fluctuates.
In one implementation, step S5 includes:
and adjusting the opening degree of the water quantity adjusting valve to the minimum gear.
For example, the maximum water outlet flow of the water heater in 10 seconds is 11.5 liters/minute, the minimum water outlet flow is 4 liters/minute, the difference is 7.5 liters/minute, and is greater than the preset difference of 3 liters/minute, and the fluctuation is large; at the moment, the opening degree of the water quantity regulating valve is regulated to the minimum gear, the maximum water outlet flow of the water heater is reduced to 6.5 liters/minute, the difference value between the maximum water outlet flow and the minimum water outlet flow is 2.5 liters/minute, and the fluctuation of the water outlet flow is controlled.
In one implementation, step S6 includes:
s601, judging whether the water outlet temperature reaches the set temperature; if yes, go to step S602; if not, executing step S603;
s602, controlling the opening of the gas proportional valve to be unchanged;
and S603, adjusting the opening of the gas proportional valve according to the demand load.
Specifically, if the outlet water temperature of the water heater reaches the set temperature, the water heater can work by maintaining the existing parameters without changing the opening degree of the gas proportional valve; if the outlet water temperature of the water heater does not reach the set temperature, the opening degree of the gas proportional valve is adjusted according to the demand load, for example, the opening degree of the gas proportional valve is adjusted to 60% so that the outlet water temperature reaches the set temperature.
According to the temperature control method of the water heater, the opening degree of the corresponding gas proportional valve is adjusted according to different set temperatures, so that the outlet water temperature of the water heater cannot change greatly at the moment of switching the opening degree of the water quantity adjusting valve, and the constant temperature performance of the water heater is improved.
