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 constant temperature water outlet provided in this embodiment includes the following steps:
s1, acquiring the current actual water inlet temperature and the actual water outlet temperature of the water heater;
s2, generating a corresponding first fuel gas adjusting strategy according to the actual water inlet temperature and the actual water outlet temperature;
s3, controlling a gas valve in the water heater to work according to a first working parameter based on the first gas adjusting strategy;
s4, controlling the water inflow of the water heater to be reduced to a set water inflow;
s5, generating a corresponding second fuel gas regulation strategy according to the set water outlet temperature of the water heater and the first fuel gas regulation strategy;
and S6, controlling the gas valve to work according to a second working parameter based on the second fuel gas regulating strategy until the water outlet temperature reaches the set water outlet temperature.
Specifically, the water heater is usually powered by electricity and gas to heat water, and when the load of the total electricity or gas in a home is large, the water heater may cause the water temperature to drop due to insufficient power supply, so that the problem of "hot and cold" of the outlet water temperature is caused, and the use experience of a user is influenced. According to the constant temperature water outlet control method of the water heater provided by the embodiment, when the energy supply of the water heater is insufficient, the load of the water heater is reduced by reducing the water inflow, and the stability of the water outlet temperature is further controlled, and two problems need to be considered in the constant temperature control method based on water amount adjustment: firstly, before the water inlet valve is controlled to reduce the water quantity, the load of the water heater is reduced (realized by reducing the current of a gas valve), and the overlarge change of the instantaneous outlet water temperature of the cut valve is avoided; after the water inlet valve is controlled to reduce the water quantity, the load of the water heater needs to be adaptively adjusted again, and the problems that the water is not heated and the set temperature cannot be reached are avoided. The first and second gas regulation strategies described above solve these two problems.
Step S1, the current actual water inlet temperature and the actual water outlet temperature of the water heater are obtained. Wherein, the actual inlet water temperature is usually related to seasons, the inlet water temperature in summer can be as high as 30 ℃, and the inlet water temperature in winter can be as low as 5 ℃; the actual outlet water temperature is constantly changing with the heating of the water heater.
And S2, generating a corresponding first gas regulating strategy according to the actual inlet water temperature and the actual outlet water temperature. Because the actual inlet and outlet water temperatures of the water heater are different, the current load of the water heater is also different, and therefore the regulating strategy of the gas is also different before the water quantity is reduced. For example, the greater the current load on the water heater, the more load needs to be reduced before reducing the water volume to avoid overheating of the water when the water is boiled after the water volume is reduced.
And S3, controlling a gas valve in the water heater to work at a first working parameter based on the first gas regulating strategy. The first operating parameter typically includes, but is not limited to, an operating current and an operating time of the gas valve. The specific working parameters of the gas valve are obtained by debugging in the testing stage.
And S4, controlling the water inflow of the water heater to be reduced to a set water inflow. Specifically, the water inlet of the water heater can be reduced by controlling the water inlet valve. The water inlet valve can adopt a water electromagnetic valve as shown in figure 2, the water electromagnetic valve comprises a first channel 1 and a second channel 2, after the coil 3 is electrified, the valve core 4 moves downwards, the membrane 5 closes the second channel 2, and the water quantity is switched to a small gear.
And S5, generating a corresponding second fuel gas regulation strategy according to the set outlet water temperature of the water heater and the first fuel gas regulation strategy. After the load is reduced and the water amount is reduced, the outlet water temperature still needs to be heated to the set temperature, so that the gas needs to be adaptively adjusted again to increase the load and avoid the problem that the water cannot be heated after being heated for a long time.
And S6, controlling the gas valve to work at a second working parameter based on the second fuel gas regulating strategy until the outlet water temperature reaches the set outlet water temperature. Specifically, the current of the gas valve can be adjusted, and heating is continued until the water outlet temperature reaches the set water outlet temperature of the user.
When the water heater is under-powered, the water may not be hot, and the amount of water is usually reduced to reduce the load on the water heater to ensure that the water is heated properly. In order to avoid the situation that the outlet water temperature is greatly fluctuated when the inlet water quantity of the water heater is reduced and the user experience is poor, the constant-temperature outlet water control method of the water heater provided by the embodiment firstly adjusts the gas valve of the water heater through a first gas adjusting strategy so as to ensure that the outlet water temperature of the water heater does not change too much before and after the water quantity is reduced, and then reduces the load of the water heater by controlling the inlet valve to reduce the inlet water quantity; and then the gas valve of the water heater is regulated by a second gas regulating strategy to ensure that the outlet water temperature is heated to the set outlet water temperature, so that the smooth transition of the outlet water temperature before and after the reduction of the water quantity is realized, the stability of the outlet water temperature is maintained, the constant temperature performance of the water heater is improved, and the use experience of a user is ensured.
Example 2
On the basis of embodiment 1, the present embodiment provides a constant temperature water outlet control method for a water heater.
In an implementable approach, referring to fig. 3, step S2 comprises:
s201, when the actual water inlet temperature corresponds to a preset water inlet temperature range, calculating to obtain a temperature difference value between the actual water outlet temperature and the set water outlet temperature;
s202, generating the corresponding first gas regulating strategy based on the temperature difference.
For example, when the actual inlet water temperature is between 5 ℃ and 20 ℃, the temperature difference between the actual outlet water temperature and the set outlet water temperature is calculated, and a corresponding first fuel gas regulation strategy is generated according to the temperature difference. Because in the heating process of the water heater, the actual water outlet temperature can be continuously increased, the temperature difference can be continuously reduced, and when the temperature difference is in different ranges, the corresponding first gas regulation strategy needs to be dynamically adjusted so as to realize accurate constant-temperature water outlet control.
The corresponding first gas adjusting strategy is generated according to different temperature difference values, so that the accuracy of the constant-temperature water outlet control method of the water heater can be improved.
In an implementation scenario, step S202 includes:
presetting the first working parameters of the gas valve corresponding to different load states;
determining the current load status of the water heater based on the temperature difference;
and determining the corresponding first working parameter according to the load state.
Specifically, the first operating parameters of the gas valve corresponding to the fact that the actual outlet water temperature does not fluctuate greatly after the water amount is reduced under different load conditions are obtained through testing, wherein the first operating parameters include but are not limited to the operating current and the operating time of the gas valve. And determining the load state of the water heater according to the temperature difference, and controlling the gas valve to heat according to a first working parameter corresponding to the load state.
The gas valve is controlled to heat with different working parameters corresponding to loads, so that the water outlet temperature is gradually transited before and after the water amount is reduced, the constant temperature performance of the water heater can be improved, and the use experience of a user is optimized.
In an implementable scheme, when the actual water inlet temperature corresponds to the preset water inlet temperature range and the temperature difference value corresponds to a preset difference value range, the constant-temperature water outlet control method further includes:
determining the current water inflow range of the water heater;
and generating a corresponding first gas regulation strategy based on the water inflow range.
For example, when the actual inlet water temperature is between 5 ℃ and 20 ℃ and the temperature difference is greater than 20 ℃, a corresponding first gas regulation strategy is generated based on the inlet water amount range.
The accuracy of the constant-temperature water outlet control method of the water heater can be further improved by generating corresponding first gas adjusting strategies for different water inflow ranges.
In an implementable aspect, the step of generating the corresponding first gas adjustment strategy based on the water intake range comprises:
determining the current load state of the water heater based on the water inflow range;
and determining the corresponding first working parameter according to the load state.
Specifically, the first working parameters of the gas valve corresponding to various load states are obtained through testing. During testing, conditions of multiple dimensions such as a water inlet temperature range, a temperature difference range, a water inlet amount range and the like are combined to obtain a first working parameter of the gas valve, wherein the water outlet temperature of the gas valve is constant.
Through the first working parameter of setting corresponding gas valve under different conditions to the smooth transition of play water temperature around realizing reducing the water yield can further improve the constant temperature performance of water heater.
In an implementation scenario, step S6 includes:
presetting the second working parameters of the gas valve corresponding to different load states;
determining the load state of the water heater based on the set outlet water temperature and the first gas regulation strategy;
determining the second operating parameter of the gas valve based on the load condition.
Specifically, after the load of the gas valve is reduced by the first gas adjusting strategy, in order to ensure that the subsequent water heater continues to heat so that the outlet water temperature reaches the set temperature, the second operating parameter of the gas valve is adjusted again correspondingly, wherein the second operating parameter includes but is not limited to the operating current and the operating time of the gas valve.
In a similar way, the second working parameter is obtained by testing under different conditions, so that the water heater can be normally heated to the parameter of the set water outlet temperature.
The load of the water heater is adjusted again through the second gas adjusting strategy, and the actual outlet water temperature can be continuously heated to the set outlet water temperature of the user after the water quantity is reduced.
It should be noted that, because each link in the process of controlling the constant-temperature water outlet is related to each other, in order to ensure that the actual water outlet temperature of the water heater is constant, optimal data of gas regulation under the conditions of different actual water inlet temperatures, temperature differences and water inlet amount ranges need to be tested.
The following describes, in conjunction with a specific embodiment, an implementation principle of the constant temperature water outlet control method for a water heater provided in this embodiment:
when the current water heater is not enough in energy supply and the outlet water temperature needs to be stable by cutting the small water amount, the constant-temperature outlet water control mode of the water heater is started:
1. actual inlet water temperature is higher than 30 DEG C
(1) The temperature difference is greater than 7 ℃: reducing the load to 50% of the current load, controlling the water electromagnetic valve to switch to a small flow by the server after lasting for 5 seconds, and adjusting the water electromagnetic valve to the minimum load for heating;
(2) The temperature difference is less than or equal to 7 ℃: and keeping the current working state for heating.
2. When the actual water inlet temperature is more than 20 ℃ and less than or equal to 30 DEG C
(1) The temperature difference is greater than 15 ℃: reducing the load to 80% of the current load, after 5 seconds, controlling the water electromagnetic valve to switch to a small flow by the server, and adjusting the water electromagnetic valve to 75% of the required load for heating;
(2) The temperature difference is greater than 7 ℃ and less than or equal to 15 ℃: if the water inflow is more than 16 liters, the load is reduced to 50% of the current load, after 2 seconds, the server controls the water electromagnetic valve to switch to a small flow, and then the water electromagnetic valve is adjusted to the minimum load for heating; if the water inflow is less than or equal to 16 liters, the load is reduced to 80% of the current load, after 2 seconds, the servo controls the water electromagnetic valve to switch to a small flow, and then the water electromagnetic valve is adjusted to the minimum load for heating.
3. When the actual water inlet temperature is more than 5 ℃ and less than or equal to 20 DEG C
(1) The temperature difference is greater than 20 ℃: if the water inflow is more than 16 liters, the server directly controls the water electromagnetic valve to switch to a small flow, and then the water electromagnetic valve is adjusted to 50% of the required load for heating; if the water inflow is less than or equal to 16 liters, the load is reduced to 80% of the current load, after 2 seconds, the server controls the water electromagnetic valve to switch to a small flow, and then the water electromagnetic valve is adjusted to 75% of the required load for heating.
(2) The temperature difference is greater than 15 ℃ and less than or equal to 20 ℃: if the water inflow is more than 16 liters, the load is reduced to 80% of the current load, after 2 seconds, the server controls the water electromagnetic valve to switch to a small flow, and then the water electromagnetic valve is adjusted to 75% of the required load for heating; if the water inflow is less than or equal to 16 liters, the load is reduced to 80% of the current load, after 5 seconds, the server controls the water electromagnetic valve to switch to a small flow, and then the water electromagnetic valve is adjusted to 75% of the required load for heating.
(3) The temperature difference is greater than 7 ℃ and less than or equal to 15 ℃: and reducing the load to 50% of the current load, and after 2 seconds, controlling the water electromagnetic valve to switch to a small flow by the server, and adjusting the water electromagnetic valve to the minimum load for heating.
4. When the actual water inlet temperature is less than or equal to 5 DEG C
The servo directly controls the water electromagnetic valve to switch to a small flow, and then the water electromagnetic valve is adjusted to 50% of the required load for heating.
And finally, returning to the constant temperature main logic of the water heater.
Wherein, the current load = (actual outlet water temperature-actual inlet water temperature) × inlet water volume; demand load = (set outlet water temperature-actual inlet water temperature) × inlet water flow; the load reduction method comprises the following steps: the current of the gas valve is reduced.
According to the constant-temperature water outlet control method for the water heater, the corresponding first fuel gas regulation strategy and the second fuel gas regulation strategy are generated according to different actual water inlet temperatures, temperature difference values and water inlet amounts, and working parameters of the gas valves are correspondingly adjusted, so that the water outlet temperature of the water heater is not greatly changed at the moment of reducing the water inlet amount, and the constant temperature performance of the water heater is improved.
