Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments.

[0046] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0047] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0048] Gas water heaters are household appliances with relatively high requirements for the environment and conditions, needing both water and gas to function properly. However, due to environmental and gas safety limitations, it is often impossible to conduct actual demonstrations of the machines in retail stores. Potential buyers can only see the specifications on paper and the appearance of the demo unit regarding performance indicators such as temperature control and noise levels, unable to truly experience the actual performance of the gas water heater. Therefore, the performance demonstrations of gas water heaters currently displayed in stores are significantly limited by the environment, affecting the product experience for consumers and hindering manufacturers from showcasing the advantages and differences of their products.

[0049] To address the issue that environmental limitations significantly impact the user's product experience when showcasing the performance indicators of gas water heater prototypes, and also hinder manufacturers from highlighting product advantages and differentiation, this application embodiment adds a noise generation module, a water tank module, a control module, an information acquisition module, a water output module, and a performance display module to the gas water heater simulation device. This allows for the simulation of the actual operating noise generated during the hot water output process of a gas water heater based on user-inputted environmental information and the model's performance parameters. Furthermore, the performance display module shows the simulated output hot water temperature curve and can mark the heating time, overshoot, and steady-state temperature control effect. This better meets user needs, improves product sales and corporate competitiveness, and allows users to better understand product performance and advantages.

[0050] To achieve the above objectives, this application provides a gas water heater simulation method applied to a gas water heater simulation device. The gas water heater simulation device includes at least a control module and a water tank module, which is used to simulate the operating conditions of a gas water heater and demonstrate a realistic water usage experience to the user.

[0051] Referring to Figure 1, which is a flowchart illustrating an embodiment of the gas water heater simulation method of this application, the gas water heater simulation method includes:

[0052] Step S10: When the start command is received, the operating conditions of the gas water heater are simulated by the virtual model preset in the control module to determine the outlet water temperature change curve.

[0053] Before step S10, the gas water heater simulation device has completed parameter initialization and user environment learning. Its external behavior (including outlet water temperature and noise) after receiving the user's start command is consistent with that of a real gas water heater. The gas water heater simulation device includes a control module, which can be a digital twin control module. This module contains a pre-built virtual model (i.e., a digital twin model) corresponding to the real gas water heater. It can simulate the temperature changes of the water output by the real gas water heater during operation based on the controller parameters, fan parameters, and key parameters of the entire unit, and displays this as an outlet water temperature change curve. The horizontal axis of the outlet water temperature change curve represents time, and the vertical axis represents temperature.

[0054] Step S20: Determine the real-time outlet water temperature based on the outlet water temperature change curve, and output the water temperature value as the real-time outlet water temperature through the water tank module.

[0055] Step S30: Visualize the water temperature change curve.

[0056] Step S20 is repeated multiple times as time changes. The outlet water temperature varies at different times; for example, it is relatively low at startup, gradually increases over time, and then stabilizes around a certain temperature. To simulate the water output of a real gas water heater, the gas water heater simulation device needs to output water at the corresponding real-time outlet water temperature according to the temperature change curve at each time point. The water tank module has the function of outputting water at the required real-time outlet water temperature. For example, the water tank module can heat the water using electric heating or by mixing pre-stored water of different temperatures to output water that meets the real-time outlet water temperature requirement.

[0057] In addition to outputting real-time water temperature, the gas water heater simulation device can also display a real-time water temperature change curve via its built-in performance display device (such as a display screen). This allows users to intuitively understand the performance of the gas water heater corresponding to the simulation device, such as the time required for heating, temperature stability, and temperature overshoot. This helps users make informed purchasing decisions and buy the gas water heater model that best suits their needs.

[0058] This application provides a gas water heater simulation method, applied to a gas water heater simulation device. The gas water heater simulation device includes at least a control module and a water tank module. The gas water heater simulation method includes: upon receiving a start command, simulating the operating conditions of the gas water heater through a preset virtual model in the control module to determine the outlet water temperature change curve; determining the real-time outlet water temperature based on the outlet water temperature change curve; outputting water with the temperature value of the real-time outlet water temperature through the water tank module in real time; and visually displaying the outlet water temperature change curve. The technical solution of this application uses a pre-constructed virtual model corresponding to the gas water heater to simulate the operating conditions of the gas water heater. It can output water with a temperature that truly reflects the operating conditions of the gas water heater without the need for gas connection, overcoming the environmental limitations of displaying performance indicators of gas water heater prototypes. This allows users to experience the temperature changes of the water flow output by the gas water heater in real-world conditions, and also displays the outlet water temperature change curve. This allows users to have an intuitive understanding of the performance indicators when purchasing a gas water heater, facilitating the selection of a gas water heater model that meets their needs. It also helps gas water heater retailers or manufacturers showcase the performance advantages of their gas water heaters, increasing product sales and corporate competitiveness.

[0059] Further, referring to Figure 6, in one embodiment, before the step of simulating the operating conditions of the gas water heater through a preset virtual model in the control module when a start command is received, the method may further include:

[0060] Step A10: Obtain the controller parameters, fan parameters, and overall parameters of the simulated gas water heater;

[0061] Step A20: Obtain preset household water environment information, which includes at least the set temperature, inlet water temperature, water pipe length, and water flow rate.

[0062] Step A30: Based on controller parameters, fan parameters, overall unit parameters, and household water environment information, construct a virtual model corresponding to the simulated gas water heater.

[0063] This application provides a method for pre-constructing a virtual model corresponding to a simulated gas water heater, wherein the virtual model is a digital twin model.

[0064] The digital twin model consists of three parts: a controller algorithm software module, a fan control algorithm software module, and a whole-machine and component simulation software module. Specifically, the controller parameters include adjustable hyperparameters reserved in the controller algorithm software module. These adjustable hyperparameters are calibrated in the laboratory for different structural models, and then finalized before leaving the factory. Therefore, the whole-machine parameters differ for different structural models. The whole-machine parameters include parameters related to the materials, structure, and configuration of the gas water heater itself.

[0065] The fan parameters refer to the adjustable hyperparameters reserved in the fan control algorithm software module, mainly including the current deviation coefficient under maximum and minimum load, and the fan duty cycle deviation coefficient. Typically, after installation at the user's home, the fan control parameters need to undergo a self-learning process on-site to update the parameters. In this embodiment, the fan parameters can complete the self-learning update process after obtaining household water environment information.

[0066] In addition, the model also needs to learn the household water environment information input by the user during the construction process. In the actual operation of the gas water heater, the set temperature, inlet water temperature, water pipe length and water flow can all affect the outlet water temperature. Therefore, in order to make the simulation accuracy of the gas water heater simulation device higher, it is also necessary to combine the household water environment information to improve the corresponding digital twin model.

[0067] For example, assuming the control model of the controller algorithm software module is f, the controller algorithm software module can be initialized by obtaining the key parameters of the current gas water heater, thus obtaining the complete controller model f. The controller model consists of two parts: a proportional valve PWM (Pulse Width Modulation) calculation model f1 and a segmented valve segmented calculation model f2.

[0068] To output the proportional valve PWM value, it needs to be calculated using model f1 and parameters such as water flow rate, inlet water temperature, set temperature, outlet water temperature at the previous time point, and operating time. Similarly, the segmented valve value can be calculated using model f2 and parameters such as water flow rate, inlet water temperature, set temperature, outlet water temperature at the previous time point, and operating time. The obtained proportional valve PWM value and segmented valve value are then input into the fan control algorithm software module. The corresponding fan speed is calculated using the adjustable hyperparameters reserved in the fan control algorithm software module. Then, the overall machine and component simulation software module calculates the outlet water temperature and the state sequence of all simulated components in the overall machine and component simulation software module based on the proportional valve PWM value, segmented valve value, fan speed, water flow rate, and inlet water temperature. By combining the outlet water temperature at each time point, the outlet water temperature change curve can be determined, thus achieving a comprehensive simulation of the actual operating conditions of a gas water heater.

[0069] For ease of understanding, as shown in Figure 2, the gas water heater simulation method in this embodiment includes the following stages: digital cloning, where the manufacturer or seller inputs the controller parameters, fan parameters, and overall parameters of the gas water heater being simulated to initialize the digital twin model in the control module, ensuring that its simulated control effect is consistent with that model; environmental learning, where the user (buyer) can input household water environment information, including set temperature, inlet water temperature, water pipe length, and common water flow, to simulate the user's water environment for the gas water heater; and real-world simulation, where, after the device is started, the operating conditions are simulated and calculated based on the digital twin model, outputting an outlet water temperature change curve. The water tank module then outputs water at the corresponding temperature based on the outlet water temperature change curve and displays the curve. Through these stages, the gas water heater simulation device can simulate the real-world usage effects of different gas water heater models and different user water environments.

[0070] In one embodiment, the water tank module includes at least a normal temperature water tank and an insulated hot water tank. The step of determining the real-time outlet water temperature based on the outlet water temperature change curve and outputting water with a temperature value equal to the real-time outlet water temperature through the water tank module may include:

[0071] Step S21: Query the corresponding real-time water temperature in the water temperature change curve based on the current time point;

[0072] Step S22: Calculate the water output ratio of the ambient temperature water tank and the insulated hot water tank based on the water temperature and real-time outlet water temperature of the ambient temperature water tank and the insulated hot water tank, respectively.

[0073] Step S23: Control the ambient temperature water tank and the insulated hot water tank to dispense water according to their respective water dispensing ratios, and mix the water dispensed from the ambient temperature water tank and the insulated hot water tank to output the mixed water. The temperature of the mixed water is equal to the real-time water dispensing temperature.

[0074] In this embodiment of the application, it is necessary to simulate the output of a gas water heater at a specified temperature (real-time outlet water temperature) in an environment without gas supply. The method adopted is to pre-store room temperature water and hot water in a room temperature water tank and an insulated hot water tank of the water tank module respectively, and then mix them in proportion to output water that meets the real-time outlet water temperature.

[0075] The system consists of two tanks: a room-temperature water tank storing readily available water (such as tap water) and an insulated hot water tank storing heated water (e.g., above 80°C). Different real-time water temperatures can be output when the water output ratios from the room-temperature and insulated hot water tanks differ. After determining the real-time water temperature and the corresponding temperatures of the room-temperature and insulated hot water tanks, the water output ratios for each tank can be determined using a pre-set function or mapping table to ensure that the actual water temperature equals the real-time water temperature. The function and mapping table can be pre-calculated through experiments or model simulations.

[0076] As the current time point changes continuously over time, the real-time water temperature also changes continuously with the water temperature change curve. At each time point, steps S22 to S23 need to be executed once to ensure that the temperature of the output mixed water matches the water temperature curve.

[0077] In one embodiment, the gas water heater simulation device further includes a sound-generating module. Referring to Figure 3, the gas water heater simulation method further includes:

[0078] Step S40: Simulate the operating conditions of the gas water heater using a virtual model to determine the fan speed change curve and the combustion heat change curve;

[0079] In simulating the operation of a gas water heater using a digital twin model in the control module, in addition to calculating the simulated outlet water temperature change curve, the operating conditions of the gas water heater's fan and combustion (burner combustion) can also be simulated. In the actual operation of a gas water heater, its fan speed and gas conditions change continuously over time. Therefore, during the simulation of the gas water heater's operating conditions, the digital twin model also outputs real-time curves of fan speed change and combustion heat change. The horizontal axis of the fan speed change curve represents time, and the vertical axis represents the fan speed. Similarly, the horizontal axis of the combustion heat change curve represents time, and the vertical axis represents the number of working burners (the more burners working, the greater the heat).

[0080] Step S50: Control the sound generation module to output the corresponding simulated fan noise signal according to the speed change in the fan speed change curve;

[0081] In this embodiment, the sound-generating module pre-stores real fan noise data of the gas water heater at various fan speeds, which can be pre-recorded. When noise simulation is needed, the control module sends the fan speed change curve to the sound-generating module, so that the sound-generating module determines the fan noise data changing over time according to the fan speed change curve, and then plays it out, thereby outputting a simulated fan noise signal based on the speed change.

[0082] Step S60: Control the sound generation module to output the corresponding simulated combustion noise signal according to the firepower change curve.

[0083] In this embodiment, the sound-generating module pre-stores real combustion noise data of the gas water heater under various burner numbers. The real combustion noise data can be pre-recorded. When noise simulation is needed, the control module sends the combustion heat change curve to the sound-generating module, so that the sound-generating module determines the fan noise data that changes over time according to the combustion heat change curve, and then plays it out, thereby outputting a simulated combustion noise signal based on the heat change.

[0084] In this embodiment, the noise of the fan and the noise of combustion are simulated by the sound-generating module, which further simulates the working state of the gas water heater, allowing users to have a better understanding of the performance indicators of the gas water heater from an auditory perspective, and improving the simulation level of the gas water heater simulation device.

[0085] In another embodiment, after determining the outlet water temperature change curve, fan speed change curve, and combustion heat change curve input by the control module, the heating time and temperature fluctuation can be analyzed from the outlet water temperature change curve. Furthermore, the noise change curve of the gas water heater can be generated by combining the fan speed change curve and the combustion heat change curve. The corresponding outlet water flow rate change curve can also be simulated and calculated. Then, the performance of this model of gas water heater in a user's household water environment is evaluated and visualized to demonstrate the performance characteristics of this model to the user. The performance evaluation dimensions of the gas water heater can include aspects such as quiet operation, energy saving, rapid heating, and constant temperature, as well as other advantages that manufacturers want to highlight or other dimensions that users are concerned about.

[0086] This example is only for the purpose of assisting in understanding this application and does not constitute a limitation on the gas water heater simulation method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0087] This application embodiment also provides a gas water heater simulation device. Referring to FIG4, the gas water heater simulation device includes at least:

[0088] The control module is used to simulate the operating conditions of the gas water heater through a preset virtual model when a start command is received, determine the outlet water temperature change curve and send it to the performance display module, determine the real-time outlet water temperature based on the outlet water temperature change curve and send the real-time outlet water temperature to the water tank module.

[0089] The water tank module is connected to the control module and is used to output water with a real-time temperature value based on the real-time outlet water temperature.

[0090] The performance display module, connected to the control module, is used to visualize the water temperature change curve sent by the control module.

[0091] The control module can be a digital twin control module, which includes a digital twin model corresponding to the simulated gas water heater. This digital twin model has completed digital cloning and environmental learning steps and can simulate the operating conditions of the gas water heater. After the gas water heater simulation device receives the start command, the digital twin control module starts simulation calculation, outputs the real-time outlet water temperature change curve, and sends it to the water tank module.

[0092] The function of the water tank module is to output water that meets the required specifications based on the real-time outlet water temperature in the outlet water temperature change curve, so as to simulate the outlet water state of a real gas water heater.

[0093] The performance display module can be a display screen, which visualizes the outlet water temperature curve output by the control module, and further analyzes the outlet water temperature curve to determine the corresponding heating time, temperature stability, etc., so as to intuitively show the performance indicators of the gas water heater model to the user.

[0094] In another embodiment, the control module can also simulate and calculate the fan speed change curve and combustion heat change curve of the gas water heater, and send them to the performance display module to calculate and display the noise index and energy saving index of the gas water heater.

[0095] Furthermore, in one embodiment, as shown in FIG4, the gas water heater simulation device further includes an information acquisition module, which is connected to the control module and is used to acquire the controller parameters, fan parameters, overall parameters and household water environment information of the simulated gas water heater, and send the controller parameters, fan parameters, overall parameters and household water environment information to the control module. The household water environment information includes at least the set temperature, inlet water temperature, water pipe length and water flow rate.

[0096] The information acquisition module can be considered as a module in the gas water heater simulation device used to interact with the user. It can be a touch screen, a physical control panel, or a combination of a wireless communication module and a remote control. It is mainly used to acquire relevant parameter information input by the manufacturer, the merchant, or the user.

[0097] For example, after the gas water heater simulation device is manufactured, the manufacturer can input the controller parameters, fan parameters, and overall parameters corresponding to the gas water heater model to be simulated to initialize the digital twin model in the control module and complete the digital cloning process. Once the gas water heater simulation device arrives at the store, the merchant can use it directly. Alternatively, the merchant can input the corresponding controller parameters, fan parameters, and overall parameters according to the gas water heater model to be displayed, performing the digital cloning process initially or repeatedly to meet the display needs of different gas water heater models. When a customer with a gas water heater purchase intention visits the store, they can input their actual household water environment information into the gas water heater simulation device, allowing the device to learn the environment and make its operation more closely match the user's household water environment. This household water environment information includes at least the set temperature (which can be customized by the user), inlet water temperature (depending on ambient temperature), water pipe length (affecting outlet water temperature), and water flow rate (affecting outlet water temperature and flow rate).

[0098] In one embodiment, as shown in FIG4, the water tank module further includes a normal temperature water tank, an insulated hot water tank, a pumping module, and a water outlet module. The pumping module is connected to the control module, the normal temperature water tank, the insulated hot water tank, and the water outlet module respectively.

[0099] Ambient temperature water tanks and insulated hot water tanks are used to store ambient temperature water and heated water, respectively.

[0100] The pumping module is used to pump water from the ambient temperature water tank and the insulated hot water tank according to the corresponding water output ratios sent by the control module, mix the water outputs from the ambient temperature water tank and the insulated hot water tank, and deliver the mixed water to the water output module.

[0101] The water outlet module is used to output mixed water to the outside, where the temperature of the mixed water is equal to the real-time outlet water temperature.

[0102] In this embodiment, water is supplied to meet the real-time outlet temperature requirement by storing water tanks of different temperatures within the water tank module. This method has the advantage of eliminating the need for gas or electric heating equipment, thus fulfilling the requirement for simulated outlet temperature. The pumping module is the core component of the water tank module, ensuring the output temperature equals the real-time outlet temperature. Connected to the control module, the pumping module calculates the corresponding outlet ratios for the ambient temperature tank and the insulated hot water tank based on the real-time outlet temperature from the outlet temperature change curve output by the control module. Alternatively, the control module calculates the corresponding outlet ratios for the ambient temperature tank and the insulated hot water tank and sends them to the pumping module. The pumping module then pumps water from the ambient temperature tank and the insulated hot water tank according to the outlet ratios sent by the control module, mixes them, and ensures the temperature of the mixed water matches the outlet temperature change curve before outputting it to the outside by the outlet module.

[0103] In one embodiment, as shown in FIG4, the gas water heater simulation device further includes a sound generation module, which is connected to the control module and is used to output simulated fan noise signal and simulated combustion noise signal respectively according to the fan speed change curve and combustion fire power change curve sent by the control module.

[0104] To further simulate the operating conditions of a real gas water heater, the gas water heater simulation device is also equipped with a sound-generating module. The sound-generating module pre-stores fan noise data and combustion noise data corresponding to different fan speeds and different combustion heat (represented by the number of working burners). When the control module outputs the fan speed change curve and the combustion heat change curve, the sound-generating module can determine the corresponding fan speed and combustion heat based on the current time point and the fan speed change curve and combustion heat change curve, and play the corresponding simulated fan noise signal and simulated combustion noise signal according to the pre-stored fan noise data and combustion noise data.

[0105] The simulated fan noise signal and the simulated combustion noise signal can be played using speakers distributed in different locations. For example, the speaker for the simulated fan noise signal can be set at the actual fan position in the gas water heater simulation device, and the speaker for the simulated combustion noise signal can be set at the actual burner position in the gas water heater simulation device, thereby achieving a more realistic noise simulation effect.
