All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0032] like Figure 1-5 As shown, this embodiment proposes a multi-point adaptive water heater detection device, including a water heater body 1. An RTD sensor 2 is installed inside the water heater body 1. An external pipe 3 is installed outside the water heater body 1, and an electric valve 4 is installed on the external pipe 3. A pressure regulating valve 5 is installed on one side of the external pipe 3. A water pipe is installed inside the water heater body 1, and the water pipe has a multi-layer structure. The number of RTD sensors 2 is the same as the number of layers in the water pipe, and multiple RTD sensors 2 are located in different layers inside the water pipe, thereby enabling the monitoring of water temperature at different points. The external pipe 3 is connected to the water pipe inside the water heater body 1. The electric valve 4 controls the inflow and outflow of water, thereby adjusting the water capacity inside the water heater body 1. The pressure regulating valve 5 adjusts the water pressure inside the water pipe inside the water heater body 1, ensuring the pressure is within a safe range.
[0033] like Figure 4 As shown, the water heater body 1 is provided with a housing 6 on the outside, and a pressure sensor 7 is provided on the inner wall of the housing 6. The pressure regulating valve 5 is electrically connected to the pressure sensor 7. The pressure sensor 7 has a built-in PID control algorithm, which can dynamically adjust the pressure regulating valve 5 according to the feedback provided by the pressure sensor 7, thereby improving the accuracy of pressure control.
[0034] like Figure 4 As shown, a processor 8 is installed on the inner wall of the housing 6. The RTD sensor 2 is electrically connected to the processor 8. When in use, to weigh the water in the water pipes inside the water heater body 1, the real-time water mass can be calculated based on the changes in temperature and water density. After monitoring the temperature using a temperature sensor, the density value can be compensated based on the temperature of the water inside the water heater body 1, thereby obtaining more accurate weighing data. Specifically: the density of water changes with temperature; the higher the temperature, the lower the density of water; the lower the temperature, the higher the density of water. This relationship can be characterized by the water density-temperature relationship. Specifically, the change in water density with temperature can be approximately described by the following formula. The formula is: p(T) = p0(1-αT), where p(T) is the density of water at temperature T, p0 is the density of water at room temperature, α is the coefficient of thermal expansion of water, and T is the temperature of the water in °C. Then, the temperature of the water in the internal water pipes of the water heater body 1 is sensed by a temperature sensor. Once the temperature is obtained and the corresponding density value is obtained using the density formula, the mass of the water can be calculated using the water volume. Assuming the volume of the internal water pipes of the water heater body 1 is V, the mass of the water can be calculated using the following formula: m = p(T) * V, where m is the mass of the water, and p(T) is the density of the water (kg / m³) calculated based on the real-time temperature T. 3 V is the volume of water (m³) 3 Meanwhile, the specific process of density compensation is as follows: assuming that the water in the water heater body 1 is being monitored and the water temperature changes significantly, the mass of the water can be estimated through temperature compensation. Each time the temperature sensor reads the temperature, the pre-set water density-temperature relationship is used to calculate the compensated density.
[0035] like Figure 1 As shown, a display screen 9 is provided on the outer wall of the housing 6. The display screen 9 is electrically connected to the water heater body 1. When in use, the display screen 9 can show whether the water heater body 1 is in operation.
[0036] like Figure 4 As shown, a number of heat dissipation holes 10 are provided on the outer wall of the housing 6. The number of heat dissipation holes 10 are evenly distributed along the width direction of the housing 6. During the operation of the water heater body 1, a large amount of heat is generated. The heat dissipation holes 10 can facilitate the heat dissipation and also help the air intake. The water heater body 1 needs sufficient air to ensure the completeness of combustion, thereby improving the efficiency of the water heater body 1.
[0037] like Figure 1 As shown, the shell 6 is made of stainless steel, and the outer tube 3 is made of copper. The stainless steel shell is not easy to rust or fade during long-term use and has good wear resistance. At the same time, the copper outer tube 3 has excellent ductility and tensile strength, which enables the copper fittings to withstand certain mechanical stress and pressure fluctuations, ensuring external stability and safety.
[0038] like Figure 4 As shown, a microcontroller 11 is installed on the inner wall of the housing 6. The RTD sensor 2, pressure sensor 7, and processor 8 are all electrically connected to the microcontroller 11. The microcontroller 11 is also wired to the display screen 9. During use, the data generated by the RTD sensor 2, pressure sensor 7, and processor 8 are transmitted to the microcontroller 11. After receiving the data from the RTD sensor 2, pressure sensor 7, and processor 8, the microcontroller 11 can perform some processing, calibration, or conversion on the data. For example, it can convert temperature data into actual temperature values or pressure signals into specific pressure values. Then, the microcontroller 11 transmits these processed data to the display screen 9 for the user to understand.
[0039] Specifically, in use, this multi-point adaptive water heater detection device works as follows: RTD sensor 2 can detect the water temperature in the internal water pipes of the water heater body 1; external pipe 3 is connected to the internal water pipes of the water heater body 1; and electric valve 4 controls the inflow and outflow of water, thereby adjusting the water capacity inside the water heater body 1. Pressure sensor 7 has a built-in PID control algorithm, which dynamically adjusts the pressure regulating valve 5 based on the feedback provided by pressure sensor 7, improving the accuracy of pressure control. To weigh the water in the internal water pipes of the water heater body 1, the real-time water mass can be calculated based on the changes in temperature and water density. After monitoring the temperature using a temperature sensor, the density value can be compensated based on the temperature of the water inside the water heater body 1, thus obtaining more accurate weighing data. Specifically, the density of water changes with temperature; the higher the temperature, the lower the density of water. The lower the temperature, the greater the density of water. This relationship can be characterized by the density-temperature relationship of water. Specifically, the change in water density with temperature can be approximately described by the following formula: p(T) = p0(1-αT), where p(T) is the density of water at temperature T, p0 is the density of water at room temperature, α is the coefficient of thermal expansion of water, and T is the temperature of water in °C. Next, the temperature of the water in the internal water pipes of the water heater body 1 is sensed by a temperature sensor. Once the temperature is obtained and the corresponding density value is obtained using the density formula, the mass of the water can be calculated using the water volume. Assuming the volume of the internal water pipes of the water heater body 1 is V, the mass of the water can be calculated using the following formula: m = p(T) * V, where m is the mass of the water, and p(T) is the density of water (kg / m³) calculated based on the real-time temperature T.3 V is the volume of water (m³) 3 The specific process of density compensation is as follows: assuming that the water in the water heater body 1 is being monitored and the water temperature varies greatly, the water mass can be estimated through temperature compensation. Each time the temperature sensor reads the temperature, the pre-set water density-temperature relationship is used to calculate the compensated density. Finally, the data generated by the RTD sensor 2, pressure sensor 7, and processor 8 are all transmitted to the microcontroller 11. After receiving the data from the RTD sensor 2, pressure sensor 7, and processor 8, the microcontroller can perform some processing, calibration, or conversion on the data. For example, the temperature data can be converted into the actual temperature value, or the pressure signal can be converted into a specific pressure value. Then, the microcontroller 11 transmits these processed data to the display screen 9 for the user to understand.
