Description

Technical Field

[0001] The present invention relates to the technical field of water heater control, and in particular to a control method and device for an electric-gas dual-purpose water heater. Background Art

[0002] Currently, the water heaters for RVs mainly adopt storage electric water heaters or instant gas water heaters, but both have significant defects: The storage electric water heater relies on electric energy for heating, with slow heating speed, unable to quickly respond to demands, and it is difficult to make full use of the free electric power resources provided by RV campsites, resulting in waste of electric energy. In addition, the storage design has problems such as large heat loss and obvious temperature fluctuations, affecting the use experience; while the instant gas water heater heats relatively fast, but in high-altitude areas, due to the thin air, the combustion is incomplete, the thermal efficiency drops significantly, and it may even fail to work properly. Therefore, the existing water heaters with a single energy mode are difficult to adapt to complex environments such as high altitudes, and cannot balance energy efficiency and use experience. Although there are already electric-gas dual-purpose water heater products on the market, there is a lack of corresponding intelligent collaborative control strategies, resulting in problems such as low energy utilization efficiency and insufficient temperature control accuracy.

[0132] Please refer to Figure 2 , Figure 2 which is a schematic flow chart of another control method for an air-electric dual-purpose water heater disclosed in an embodiment of the present invention. Optionally, this method can be implemented by a water heater intelligent control device, which can be integrated in the air-electric dual-purpose water heater, or can be a local server or a cloud server for processing the control process of the air-electric dual-purpose water heater, etc., which is not limited in the embodiments of the present invention. As Figure 2 shown, the control method of the air-electric dual-purpose water heater may include the following operations:

[0133] 201. Obtain the target water inlet parameters and user usage requirement parameters of the target water heater.

[0134] 202. When the user usage requirement parameters include water usage temperature parameter, water usage time parameter, total water usage parameter, and water usage flow rate parameter, determine whether the first difference between the water inlet temperature parameter and the water usage temperature parameter is greater than or equal to a preset difference threshold according to the water inlet temperature parameter.

[0135] In the embodiments of the present invention, further, the difference threshold can be determined in the following manner: According to the environmental parameters of the environment where the target water heater is located (such as temperature parameter, humidity parameter, wind direction parameter, wind volume parameter, etc.), the target sunlight parameters (such as sunlight intensity parameter and sunlight position parameter at the water inlet pipe of the target water heater), and the water inlet pipe parameters (such as water inlet pipe material parameter, water inlet pipe specification parameter, water inlet pipe layout parameter, etc.), predict the water inlet temperature fluctuation situation of the target water heater; Determine the difference threshold corresponding to the target water heater according to the water inlet temperature fluctuation situation.

[0136] 203. When it is determined that the first difference is greater than or equal to the difference threshold, determine that the water heater control mode matching the user includes the electric water heater control mode.

[0137] In the embodiments of the present invention, it can be understood that when the user's water usage requirements can be met with less heating energy, the electric water heater is preferentially used for water heating. In this way, the relatively warm water inlet can be stored / used, optimizing the energy usage process and reducing the usage amount of non-renewable energy.

[0138] 204. When it is determined that the first difference is less than the difference threshold, obtain the water storage parameters corresponding to the electric water heater, and determine the required operating energy type of the target water heater according to the water storage parameters, the target water inlet parameters, and the user usage requirement parameters.

[0139] 205. When the operating energy type includes the electric energy type, determine that the water heater control mode matching the user includes the electric water heater control mode.

[0140] In an embodiment of the present invention, it can be understood that within a preset future time period, if an electric water heater can heat the incoming water / stored water to meet the user's needs, the electric water heater is preferentially used for the water heating operation.

[0141] 206. When the operating energy type includes a gas energy type, determining the water heater control mode matching the user includes a gas water heater control mode.

[0142] In an embodiment of the present invention, it can be understood that within a preset future time period, if the electric water heater cannot heat the incoming water / stored water to meet the user's needs, but the user's water flow rate does not exceed the threshold, the gas water heater can be used for the water heating operation to accelerate the water heating process.

[0143] 207. When the operating energy type includes a gas-electric energy type, determining the water heater control mode matching the user includes a combined control mode of a gas-electric water heater.

[0144] In an embodiment of the present invention, it can be understood that within a preset future time period, if the electric water heater cannot heat the incoming water / stored water to meet the user's needs, and the user's water flow rate exceeds the threshold, the electric water heater can be first used for storing water heating, and the stored water after heating is controlled to flow into the water inlet pipe of the gas water heater, and then the gas water heater is used for heating the stored water after heating and the original incoming water, so as to perform the water heating operation at the fastest heating speed.

[0145] It should be noted that through the above process of determining the control mode, problems such as poor adaptability to high-altitude environments, low energy utilization efficiency, slow heating speed, and insufficient constant temperature control of existing RV water heaters can be solved.

[0146] 208. According to the water heater control mode, perform a water heating control operation on the target water heater.

[0147] In an embodiment of the present invention, for other descriptions of steps 201 and 208, please refer to the detailed descriptions of steps 101 and 103 in Embodiment 1, and the embodiments of the present invention will not be repeated here.

[0148] It can be seen that implementing the embodiments of the present invention can first dynamically calibrate the water inlet temperature fluctuation threshold based on environmental parameters, sunlight conditions, and pipeline characteristics, achieving precise prediction of energy demand. Furthermore, with the real-time comparison between the water inlet temperature difference and the dynamic threshold as the core, combined with the triple constraints of the electric water storage capacity, heating capacity, and user flow threshold, it can intelligently match three modes: electric heating priority, gas relay, or gas-electric collaboration. This not only maximizes the zero-emission characteristics of electric heating in low-load scenarios but also responds to normal hot water flow demands through the rapid response ability of the gas side. Moreover, in extreme working conditions, it achieves dual-heat-source gradient complementarity in the combined mode to cope with higher hot water flow demands. It can ensure water temperature stability while deeply coupling the selection of energy types with user demand intensity and environmental dynamic interference, ultimately achieving three-dimensional optimization of energy efficiency, comfort, and resource sustainability.

[0149] In an optional embodiment, determining the operating energy type required for the target water heater according to the water storage parameters, target water inlet parameters, and user usage demand parameters in step 204 above includes:

[0150] Determine the target heating water volume parameter corresponding to the electric water heater according to the water inlet volume parameter and the water storage volume parameter;

[0151] Obtain the maximum heating power parameter of the electric water heater, and predict the maximum heated temperature parameter of the target water for the target heating water volume parameter within the target time period corresponding to the water usage time parameter according to the water inlet temperature parameter, water inlet volume parameter, water storage volume parameter, water storage temperature parameter, and the maximum heating power parameter;

[0152] Calculate the second difference between the maximum heated temperature parameter and the water usage temperature parameter, and determine the operating energy type required for the target water heater according to the second difference.

[0153] In this optional embodiment, further, determining the operating energy type required for the target water heater according to the second difference includes:

[0154] Judge whether the second difference is greater than or equal to the difference threshold;

[0155] When it is judged that the second difference is less than the difference threshold, determine that the operating energy type required for the target water heater includes the gas energy type;

[0156] When it is judged that the second difference is greater than or equal to the difference threshold, judge whether the target heating water volume parameter is greater than or equal to the total water usage parameter;

[0157] When it is judged that the target heating water volume parameter is less than the total water usage parameter, determine that the operating energy type required for the target water heater includes the gas energy type;

[0158] When it is determined that the target heating water volume parameter is greater than or equal to the total water consumption parameter, it is determined whether the water flow parameter is less than or equal to a preset water flow threshold value;

[0159] When it is determined that the water flow parameter is greater than the water flow threshold value, it is determined that the operating energy type required by the target water heater includes the gas-electric energy type;

[0160] When it is determined that the water flow parameter is less than or equal to the preset water flow threshold value, it is determined that the operating energy type required by the target water heater includes the electric energy type.

[0161] It can be seen that this optional embodiment can establish a quantitative evaluation system for the electric heating capacity, predict the reachable temperature of electric heating based on the inlet water-storage parameters and heating capacity, and form a dynamic energy type selection logic with the "temperature gap (second difference) → water storage satisfaction → flow intensity" as the decision chain: when the electric heating cannot make up the temperature gap or the water storage is insufficient, the gas is enabled to ensure the basic supply, and the gas-electric collaborative mode is activated to improve the response speed under high flow demand. Only pure electric heating is used when the water storage is sufficient, the flow is low, and the temperature is reachable, realizing the precise adaptation of the energy type to the water use load, and meeting the user's hot water use demand as much as possible, improving the user experience.
