[0028] Energy storage heat exchange electric water heaters are highly efficient and energy-saving hot water supply equipment, widely used in home and commercial environments. This type of water heater usually includes a variety of energy storage solutions, such as storing heat through phase change material energy storage or water energy storage. Before or during use, it is necessary to ensure that the energy storage part (such as the water storage tank) and the internal pipes of the water heater are filled with water to ensure that the system can operate normally and provide constant temperature hot water.

[0029] At present, the existing water replenishment plan is that after the equipment is installed, the after-sales technician needs to manually control the hot water faucet at the end of the user's home to release water. After the water flows out evenly, the after-sales staff observes the uniformity and stability of the water flow and combines personal experience to judge whether the water replenishment is completed.

[0030] However, it is difficult to accurately assess the water replenishment status based solely on subjective judgment of personal experience, which may lead to insufficient or excessive water replenishment and affect the normal operation of the system.

[0031] In addition, since the water tank is relatively large and the heat exchange pipe is relatively long, the time required for water replenishment is also relatively long, for example, it takes more than ten minutes. Therefore, manual judgment is time-consuming and labor-intensive.

[0032] In order to solve the above-mentioned technical problems in the prior art, the present application provides a water replenishment control method for a water heater, which can automatically complete the water replenishment operation, thereby improving the accuracy of the water replenishment control of the water heater.

[0033] See also Figure 1 , Figure 1 A water replenishment control method for a water heater provided in an embodiment of the present application, the water heater comprises a water storage tank, the water storage tank is provided with a high liquid level sensor, and the method comprises the following steps: Step 110: upon receiving the water replenishment trigger instruction, determining whether the high liquid level sensor detects a water flow signal.

[0034] Step 120: If the high liquid level sensor does not detect a water flow signal, the water heater is replenished with water.

[0035] Step 130: Obtain the water inlet temperature and the water outlet temperature after water replenishment.

[0036] Step 140: Determine whether the temperature difference between the water inlet temperature after the water replenishment and the water outlet temperature after the water replenishment is less than or equal to a preset value.

[0037] Step 150: If the temperature difference between the water inlet temperature after the water replenishment and the water outlet temperature after the water replenishment is less than or equal to a preset value, the water replenishment operation is terminated.

[0038] This embodiment can automatically determine whether the high liquid level sensor detects a water flow signal when receiving a water replenishment trigger instruction. If the high liquid level sensor does not detect a water flow signal, the water replenishment process is automatically started, and by monitoring the water inlet temperature and the water outlet temperature after water replenishment, when the temperature difference between the water inlet temperature and the water outlet temperature after water replenishment is less than or equal to a preset value, the water replenishment operation is automatically terminated to avoid excessive waste of water resources. In this way, by monitoring the water inlet temperature and the water outlet temperature after water replenishment and determining whether the temperature difference meets the preset value, it is possible to more accurately determine whether the water replenishment is completed, thereby avoiding errors caused by visual perception and experience judgment in traditional manual methods, thereby improving the accuracy of water heater replenishment control.

[0039] In addition, through the automated hydration process, users do not need to personally participate in complex hydration operations, which reduces the user's waiting time and improves hydration efficiency and user experience.

[0040] If the water tank is not fully replenished, the water tank is prone to dry-burning, and if the heat exchange pipeline is not fully replenished, the user may encounter a situation where some hot water flows out during use, which not only affects the user experience, but also poses a safety hazard. Therefore, the water replenishment operation of the present application includes water tank replenishment and heat exchange pipeline replenishment. For details, please refer to the second embodiment of a water replenishment control method for a water heater provided by the present application. The second embodiment includes the following steps: Step 210: upon receiving the water replenishment trigger instruction, determining whether the high liquid level sensor detects a water flow signal.

[0041] Step 220: If the high liquid level sensor does not detect a water flow signal, the three-way valve is adjusted to a preset angle A to replenish the water tank.

[0042] Wherein, the three-way valve is used to output water to the water tank at the angle A.

[0043] In some embodiments, the water tank is further provided with a low liquid level sensor, and step 210 may be: upon receiving a water replenishment trigger instruction, determining whether the high liquid level sensor and the low liquid level sensor detect a water flow signal.

[0044] Exemplarily, if the high liquid level sensor detects a water flow signal and the low liquid level sensor does not detect a water flow signal, a prompt signal indicating that the liquid level sensor is faulty is issued.

[0045] In some embodiments, if both the high liquid level sensor and the low liquid level sensor detect water flow signals, it means that the water tank is full and does not need to be replenished.

[0046] Step 230: Determine whether the water tank has been fully refilled.

[0047] In some implementations, step 230 may be to determine whether both the high liquid level sensor and the low liquid level sensor detect a water flow signal.

[0048] If both the high liquid level sensor and the low liquid level sensor detect water flow signals, it is determined that the water tank is fully refilled.

[0049] If any one of the high liquid level sensor and the low liquid level sensor does not detect a water flow signal, or if both the high liquid level sensor and the low liquid level sensor do not detect a water flow signal, it is determined that the water tank refilling is not completed.

[0050] In other embodiments, during the process of replenishing the water tank, the water flow rate q entering the water inlet can be recorded. If the water flow rate q entering the water inlet has reached the volume of the water tank, it can be directly determined that the water tank is fully replenished. In this way, when the high liquid level sensor and the low liquid level sensor fail, the water replenishment status of the water tank can be accurately determined, and when the water tank is fully replenished, the angle of the three-way valve can be adjusted in time to replenish the heat exchange pipeline.

[0051] Step 240: If the water tank is fully replenished, the three-way valve is adjusted to a preset angle B to replenish the heat exchange pipeline.

[0052] Wherein, the three-way valve is used to output the water output from the heat exchange pipeline to the water outlet when at the B angle.

[0053] In some embodiments, if the water tank is not fully refilled, the process returns to step 220 to adjust the three-way valve to a preset angle A to refill the water tank.

[0054] Step 250: Obtain the water inlet temperature after water replenishment and the water outlet temperature after water replenishment.

[0055] Step 260: Determine whether the temperature difference between the water inlet temperature after the water replenishment and the water outlet temperature after the water replenishment is less than or equal to a preset value.

[0056] Among them, the preset value can be 1°C, 1.5°C, 2°C, 2.5°C, etc., and can be set specifically according to actual conditions, and this application does not limit it here.

[0057] Step 270: If the temperature difference between the water inlet temperature after the water replenishment and the water outlet temperature after the water replenishment is less than or equal to a preset value, the water replenishment operation is terminated.

[0058] Among them, if the temperature difference between the water inlet temperature after the water replenishment and the water outlet temperature after the water replenishment is less than or equal to the preset value, the three-way valve is adjusted to the preset C angle, and a prompt is given that the water replenishment is completed. Among them, the three-way valve is used to output the cold water output from the water inlet to the water outlet at the C angle.

[0059] Step 280: If the temperature difference between the water inlet temperature after the water replenishment and the water outlet temperature after the water replenishment is greater than the preset value, return to the step of adjusting the three-way valve to the preset B angle to replenish the heat exchange pipeline.

[0060] Based on the above embodiments, the present application provides a water replenishment control system for a water heater. The water replenishment control system for the water heater includes a water heater and a controller. The controller is used to execute the method steps provided in the above embodiments.

[0061] See also Figure 2 The water heater includes a water tank 10, a heat exchange pipeline 20, a three-way valve 30 and a water inlet valve 40. The water heater is provided with a water inlet temperature sensor 51, a water outlet temperature sensor 52, a low liquid level sensor 53 and a high liquid level sensor 54. The water inlet valve 40 is provided at the water inlet 01 of the water heater, and a water flow sensor can be integrated inside the water inlet valve 40 to detect the water flow at the water inlet 01; the low liquid level sensor 53 and the high liquid level sensor 54 can be used to detect the current water volume of the water tank 10.

[0062] The three-way valve 30 is disposed at the water outlet 02 of the water heater, and is respectively connected to the water storage tank 10, the heat exchange pipeline 20, the water inlet valve 40 and the water outlet 02. Figure 3As shown, when the three-way valve 30 is adjusted to the preset angle A, the cold water flowing into the water inlet 01 is input into the water storage tank 10 through the three-way valve 30 to replenish the water storage tank 10; Figure 4 As shown, when the three-way valve 30 is adjusted to the preset angle B, the cold water flowing into the water inlet 01 is input into the heat exchange pipeline 20 to replenish the heat exchange pipeline 20, and the heat exchange pipeline 20 then outputs the hot water obtained after heat exchange to the water outlet 02 through the three-way valve 30; Figure 5 As shown, when the three-way valve 30 is adjusted to the preset angle C, the cold water input from the water inlet 01 is directly output to the water outlet 02 through the three-way valve 30 without passing through the water tank 10. Therefore, when the three-way valve 30 is adjusted to the preset angle C, the water output from the water outlet 02 is cold water.

[0063] In some embodiments, the three-way valve 30 may be a water mixing valve. When the three-way valve 30 is between angle B and angle C, the ratio between the cold water flowing into the water inlet 01 and the hot water output from the heat exchange pipeline 20 may be adjusted.

[0064] Based on the above-mentioned water replenishment control system of the water heater, the water replenishment control method of the water heater provided in the present application may include the following steps: Step 11: Power on the device.

[0065] The device may be a water heater.

[0066] Step 12: Rehydrate with one click.

[0067] That is, after the equipment is installed, open the water inlet valve, and the user can click the operation button on the water heater. When the user clicks the operation button on the water heater, the controller can receive the water replenishment trigger instruction and start the automatic water replenishment operation.

[0068] When entering the one-key water replenishment mode, the device can display the water replenishment code and remind the user that the device is in the water replenishment state and is temporarily unavailable.

[0069] Step 13: Determine high and low liquid levels.

[0070] If the low liquid level = 1 and the high liquid level = 1, execute step 24: the water tank is full and no water replenishment is needed; if the low liquid level = 1 and the high liquid level = 0, or the low liquid level = 0 and the high liquid level = 0, execute step 14; if the low liquid level = 0 and the high liquid level = 1, execute step 34: display the fault code E1 and send a signal of liquid level sensor failure.

[0071] That is, read the detection values of the high-level sensor and the low-level sensor, and determine whether the high-level sensor and the low-level sensor detect a water flow signal. When the signal of the liquid level sensor (such as the low-level sensor or the high-level sensor) is 1, it means that the liquid level sensor can detect a water flow signal. When the signal of the liquid level sensor (such as the low-level sensor or the high-level sensor) is 0, it means that the liquid level sensor cannot detect a water flow signal.

[0072] Step 14: Adjust the three-way valve to angle A.

[0073] Step 15: Fill the water storage tank.

[0074] Step 16: Determine whether the low liquid level = 1 and the high liquid level = 1.

[0075] If so, execute Step 17. If not, return to Step 15.

[0076] Step 17: Adjust the three-way valve to angle B.

[0077] Step 18: Fill the heat exchange pipeline.

[0078] Step 19: Determine |T 进水 -T 出水 | <= 1.

[0079] That is, determine the inlet water temperature T 进水 after the water filling and the outlet water temperature T 出水 after the water filling, and whether the temperature difference between them is less than or equal to the preset value 1.

[0080] If so, execute Step 20. If not, return to Step 18.

[0081] Step 20: Adjust the three-way valve to angle C.

[0082] When the three-way valve is at angle C, it means that the filling of the heat exchange pipeline is completed, the water heater resumes the standby state and the buzzer gives a prompt, completing the entire water filling process.

[0083] In summary, the present application adopts a one-key automatic water filling control scheme, which can realize automatic water filling and automatically and timely cut off the water flow through the water storage tank after the water filling is completed, reducing water waste. In addition, through the automated water filling process, users do not need to participate in complex water filling operations personally, reducing the waiting time of users, improving the water filling efficiency and the user experience.

[0084] Corresponding to the above water filling control method of the water heater, the present application also provides a water filling control device for a water heater. The water filling control device for the water heater includes a unit for executing the above water filling control method of the water heater, and the water filling control device for the water heater can be configured in terminals such as desktop computers, tablet computers, laptops, etc.
