[0002] In the technological evolution of gas water heaters, gas valve control has always been the core link to ensure the safe and efficient operation of the equipment. The current mainstream technology uses solenoid valves or proportional valves as actuators, and integrates multi-source data such as water temperature sensors and water flow sensors through electronic controllers to achieve dynamic adjustment of gas flow.

[0003] However, there are still significant defects in the existing water heater gas valve control technology. The type of data it monitors is relatively simple and fixed, and it is difficult to flexibly respond to complex and changeable actual working conditions. Especially in the scenario where the water temperature fluctuates greatly due to seasonal changes, the stability of the water temperature decreases significantly, which not only directly affects the user's comfort experience, but also may bring safety hazards.

[0036] Embodiment 2 See also Figure 2 , Figure 2 1 is a flow chart of another gas valve intelligent control method for a water heater disclosed in an embodiment of the present invention. Optionally, the method can be implemented by a gas valve intelligent control device, which can be integrated in a gas water heater, or can be a local server or cloud server for processing the gas valve intelligent control process of the water heater, etc., which is not limited in the embodiment of the present invention.

[0039] In the embodiment of the present invention, optionally, the target parameters of all target components include at least one of the target operating parameters of the fan, the target air supply parameters of the air supply module, and the target state parameters of the flue. The target parameter of each target component may be the current parameter of the target component or a future parameter in a future time period.

[0040] Further optionally, the target operating parameters of the fan include at least one of the target speed of the fan, the target wind direction generation parameters and the target wind force generation parameters, the target gas supply parameters of the air supply module include at least one of the target gas type parameters, the target gas ratio parameters, the target gas volume parameters, the target gas flow rate parameters and the target gas flow direction parameters, and the target state parameters of the flue include at least one of the specification parameters, the opening size parameters, the opening direction parameters and the material parameters.

[0041] Furthermore, the water heater can be equipped with a display that can display the water temperature, working status (such as heating, standby, etc.), operating information / fault information of each component in real time, so that the user can intuitively understand the overall operation of the water heater, which is convenient for timely detection and processing of problems.

[0042] 204. Determine the operation adjustment parameters for the gas valve according to the predicted heating effect parameters of the water heater, the target water inlet parameters, the user's water demand parameters and the target operation parameters of the gas valve, and perform operation adjustment operations on the gas valve according to the operation adjustment parameters so that the water heater can heat and adjust the target water inlet.

[0043] In the embodiment of the present invention, for other descriptions of step 201 - step 202, please refer to the detailed description of step 101 - step 102 in the first embodiment, and the embodiment of the present invention will not be repeated.

[0044] It can be seen that the implementation of the embodiment of the present invention can first obtain the target water inlet parameters of the water heater, the user's water demand parameters, the target operating parameters of the gas valve, and the target parameters of at least one target component (such as a fan, an air supply module, a flue, etc.), and then determine the predicted heating effect parameters of the water heater based on the target parameters of all target components and the target operating parameters of the gas valve, and then determine the operating adjustment parameters for the gas valve in combination with the predicted heating effect parameters, so as to optimize the target water inlet heating through the operating adjustment parameters of the gas valve, which is beneficial to improving the reliability and accuracy of determining the operating adjustment parameters of the gas valve, thereby facilitating the precise control process of the gas valve; at the same time, the water heater is equipped with a display that can display the water temperature, working status and operation / fault information of each component in real time, which can effectively ensure that the heating effect of the water heater meets user needs, and is convenient for users to intuitively understand the operating conditions and deal with problems in a timely manner.

[0045] In an optional embodiment, the step 203 above determines the predicted heating effect parameters of the water heater according to the target parameters of all target components and the target operating parameters of the gas valve, including: When the target parameters of all target components include the target operating parameters of the fan, the target air supply parameters of the air supply module, and the target state parameters of the flue, the combustion chamber condition of the water heater is determined according to the target parameters of all target components and the target operating parameters of the gas valve; According to the combustion chamber conditions of the water heater, the predicted heating effect parameters of the water heater are determined.

[0046] In this optional embodiment, optionally, the combustion chamber condition includes at least one of the flame temperature condition, flame size condition, flame color condition, flame sway condition, exhaust gas generation condition and exhaust gas flow condition in the combustion chamber of the water heater; and the predicted heating effect parameter includes at least one of the water outlet temperature parameter, water outlet flow rate parameter and heat generation utilization rate parameter.

[0047] Furthermore, computational fluid dynamics can be used to simulate the flow field distribution of the gas (such as natural gas, artificial coal gas, etc.)-air mixture in the combustion chamber, and then the heat exchange efficiency can be calculated in combination with the thermodynamic equation to determine the heat production utilization rate parameters.

[0048] It can be seen that this optional embodiment can determine the combustion chamber condition of the water heater through the fan target operating parameters, the air supply module target air supply parameters, the flue target state parameters and the gas valve target operating parameters, and then determine the water outlet temperature, flow rate and heat production utilization rate and other predicted heating effect parameters based on the combustion chamber condition. In this way, the multi-component parameters and the gas valve operation information can be deeply integrated, and the combustion chamber condition can be used as a bridge to build a precise relationship between the parameters and the heating effect, effectively reducing the heating deviation caused by isolated parameter analysis or simple estimation, thereby ensuring that the water heater can stably output hot water that meets the expectations under different working conditions, greatly improving the controllability and reliability of the heating effect.

[0049] In another optional embodiment, the above steps of determining the combustion chamber condition of the water heater according to the target parameters of all target components and the target operating parameters of the gas valve include: Obtaining a first environmental parameter of the environment in which the water heater is located; Analyze the influence of the wind pressure of the fan on the combustion chamber of the water heater according to the first environmental parameter and the target operating parameter of the fan, and analyze the influence of the flue on the combustion chamber of the water heater caused by the flue according to the first environmental parameter and the target state parameter of the flue; The flame generation condition of the combustion chamber is determined according to the target parameters of all target components and the target operating parameters of the gas valve, and the combustion chamber condition of the water heater is determined according to the influence of wind pressure, the influence of air flow backflow and the flame generation condition.

[0050] In this optional embodiment, optionally, the first environmental parameter includes at least one of an environmental wind direction parameter, an environmental wind force parameter, and an environmental wind temperature parameter.

[0051] It should be noted that the flow field distribution of the gas (such as natural gas, artificial coal gas, etc.)-air mixed gas in the combustion chamber can be simulated by fluid dynamics to truly reflect the flow characteristics of the mixed gas under different gas supply conditions; at the same time, combined with the target operating parameters of the fan, the influence of the fan on the gas flow and mixing in the combustion chamber can be accurately simulated, making the simulation results of the mixed gas flow field distribution more realistic. In addition, since the flue parameters will change the flow path and speed of the exhaust gas, affecting the heat exchange between the combustion chamber and the outside world, by incorporating these parameters into the thermodynamic calculation model, the combustion chamber conditions of the water heater can also be determined more accurately.

[0052] It can be seen that this optional embodiment can first combine the environmental parameters and the fan target operating parameters to analyze the influence of wind pressure, and the environmental parameters and the flue target state parameters to analyze the influence of airflow backflow, and then combine all target component target parameters and gas valve target operating parameters to determine the flame generation situation, and then integrate the wind pressure, airflow backflow and flame generation situation to obtain the combustion chamber situation. In this way, the actual operating state of the combustion chamber can be more realistically and accurately reflected, and the abnormal combustion caused by ignoring environmental factors can be effectively reduced, ensuring that the water heater can maintain a stable and efficient combustion effect in different environments and working conditions, thereby improving the heating performance and operating reliability.

[0053] In yet another optional embodiment, before determining the operation adjustment parameters for the gas valve according to the predicted heating effect parameters of the water heater, the target water inlet parameters, the user water demand parameters and the target operation parameters of the gas valve in the above step 204, the method further includes: Obtaining a second environmental parameter of the environment in which the water heater is located; Determine the harmful gas generation of the water heater in a preset future time period according to the combustion chamber condition of the water heater, the target state parameter of the flue and the second environmental parameter; Determine the negative impact degree of the water heater according to the generation of harmful gases, and judge whether the negative impact degree is greater than or equal to a preset negative impact degree threshold; When the judgment result is yes, the operation adjustment parameters for the gas valve are determined according to the generation of harmful gases, the predicted heating effect parameters of the water heater, the target water inlet parameters, the user's water demand parameters and the target operation parameters of the gas valve; When the judgment result is no, the operation adjustment parameters for the gas valve are determined according to the predicted heating effect parameters of the water heater, the target water inlet parameters, the user water demand parameters and the target operation parameters of the gas valve.

[0054] In this optional embodiment, optionally, the second environmental parameter includes at least one of an environmental airtightness parameter, an environmental wind direction parameter, an environmental wind force parameter, and an environmental wind temperature parameter, and the harmful gas generation situation includes at least one of the harmful gas generation type situation (such as the generation of carbon monoxide, nitrogen oxides, hydrocarbons, sulfides, etc.), harmful gas generation concentration situation, harmful gas generation volume situation, and harmful gas generation location situation.

[0055] It can be seen that this optional embodiment can combine the combustion chamber situation, the target state parameters of the flue and the second environmental parameters to determine the generation of harmful gases, and evaluate the degree of negative impact on the operation of the water heater accordingly. When the negative impact exceeds the threshold, the adjustment parameters are determined by comprehensively considering the generation of harmful gases, the predicted heating effect parameters, the target water inlet parameters, the user's water demand parameters and the target operating parameters of the gas valve. In this way, the environmental factors, the combustion chamber and flue conditions and the risk of harmful gas generation are deeply integrated to form a dynamic and comprehensive safety guarantee mechanism, which can intervene in advance when the potential risk of harmful gases is high, optimize the operation of the gas valve to reduce the risk, and maintain efficient heating when the risk is controllable, taking into account both safety and performance.

[0056] In yet another optional embodiment, the above steps of determining the degree of negative impact on the operation of the water heater according to the generation of harmful gases include: Get the target user parameters of the user; Analyze the impact on the user's target based on the target user parameters and the generation of harmful gases; Determine the degree of negative impact on the operation of the water heater based on how the user's goals are affected.

[0057] In this optional embodiment, optionally, the target user parameters include body condition parameters, sensitive gas parameters, motion condition parameters and user position parameters, and the target affected conditions include physiological affected conditions and / or psychological affected conditions.

[0058] For example, when a user inhales a large amount of carbon dioxide, he or she may faint, which will seriously affect the user's physical condition. In this case, it can be determined that the negative impact of the corresponding operation of the water heater is too great. For example, when a user inhales a small amount of sulfide, but the pungent smell causes the user to feel nauseous and retching, in this case, it can also be determined that the negative impact of the corresponding operation of the water heater is too great.

[0059] It can be seen that this optional embodiment can intelligently analyze the impact on the user's target according to the user's target user parameters and the generation of harmful gases, and then determine the corresponding negative impact on the operation of the water heater. This is conducive to improving the reliability and accuracy of determining the corresponding negative impact on the operation of the water heater, and further helps to improve the reliability and accuracy of determining the subsequent operation adjustment parameters for the gas valve, thereby facilitating the precise control of the gas valve.

[0060] In yet another optional embodiment, before determining the operation adjustment parameters for the gas valve according to the predicted heating effect parameters of the water heater, the target water inlet parameters, the user water demand parameters and the target operation parameters of the gas valve in the above step 204, the method further includes: When the combustion chamber condition includes the flame temperature condition, exhaust gas generation condition and exhaust gas flow condition in the combustion chamber, the valve parameters of the gas valve are obtained, and the influence of the gas valve is analyzed according to the target gas supply parameters of the gas supply module, the flame temperature condition in the combustion chamber and the valve parameters; According to the impact of the gas valve, determine the impact degree of the operation adjustment of the gas valve, and judge whether the impact degree of the operation adjustment is greater than or equal to a preset impact degree threshold; When the judgment result is yes, the operation adjustment parameters for the gas valve are determined according to the impact of the gas valve, the predicted heating effect parameters of the water heater, the target water inlet parameters, the user's water demand parameters and the target operation parameters of the gas valve; When the judgment result is no, the operation adjustment parameters for the gas valve are determined according to the predicted heating effect parameters of the water heater, the target water inlet parameters, the user water demand parameters and the target operation parameters of the gas valve.

[0061] In this optional embodiment, the valve parameters may include at least one of valve specification parameters, valve material parameters and valve installation parameters, and the affected conditions may include heat conditions and / or gas viscosity conditions. The heat conditions may be understood as thermal expansion and deformation conditions, and the gas viscosity conditions may be understood as the valve opening / opening area adjustment process becoming slow / too fast due to the influence of airflow and temperature.

[0062] It can be seen that this optional embodiment can deeply analyze the impact of the gas valve by obtaining the gas valve parameters and combining the target gas supply parameters of the gas supply module with the flame temperature, and then evaluate the degree of impact on the operation adjustment accordingly. When the degree exceeds the threshold, the adjustment parameters are determined by comprehensively considering the impact of the gas valve, the predicted heating effect, the target water inlet, the user's water demand and the target operating parameters of the gas valve. In this way, the potential risk of the gas valve being disturbed by the combustion chamber environment can be accurately captured, and intervention can be made in advance when the risk is high to optimize the adjustment strategy, which not only reduces the impact of abnormal response of the gas valve on the heating effect and safety, but also ensures the efficient operation of the water heater when the risk is controllable, realizing the intelligence and reliability improvement of the gas valve operation adjustment.

In this way, the multi-component parameters and gas valve operation information can be deeply integrated, and the precise relationship between the parameters and the heating effect can be established with the combustion chamber condition as a bridge, effectively reducing the heating deviation caused by isolated parameter analysis or simple estimation, thereby ensuring that the water heater can stably output hot water that meets the expectations under different working conditions, greatly improving the controllability and reliability of the heating effect.
