Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0052] It should be noted that the embodiments in the present application and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0053] It should be noted that: similar labels and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Embodiment 1

[0054] Please refer to Fig. 1, the cold and hot water temperature control system, its hot water storage module, the hot water storage module is responsible for storing and heating water in advance, so as to provide hot water to the mixing unit when needed.

[0055] Cold water storage module, responsible for storing and refrigerating water in advance to provide cold water to the mixing unit when needed.

[0056] Display module, the core interactive part of the cold and hot water temperature control system, responsible for showing the current system status to the user, allowing the user to input the preset temperature, and recording user operation information, etc. During the working process of the mixing unit, the display module updates the current water temperature, mixing progress, and other information in real time.

[0057] Controller, the core component of the cold and hot water temperature control system, responsible for receiving instructions sent by the display module, controlling the working state of the hot water storage module, cold water storage module, and mixing unit, etc. to ensure that the system mixes according to the user's set temperature.

[0058] Mixing unit, responsible for extracting the appropriate amount of hot water and cold water from the hot water storage module and cold water storage module, respectively, and mixing the water into the user's preset water temperature. The mixing unit receives control signals from the controller, including the preset water temperature value and the mixing ratio. According to the control signal, the mixing unit extracts the appropriate amount of hot water and cold water from the hot water storage module and cold water storage module. Inside the mixing unit, hot water and cold water are mixed according to the preset mixing ratio.

[0059] The mixing unit uses the following algorithm formula:

[0060] Assuming that the user's preset water temperature is T_target, the water temperature in the hot water storage module is T_hot, and the water temperature in the cold water storage module is T_cold. The mixing unit needs to calculate the mixing ratio R_hot and R_cold of hot water and cold water (where R_hot + R_cold = 1);

[0061] The following formula can be used to calculate the mixing ratio:

[0062] R_hot = (T_target - T_cold) / (T_hot - T_cold)

[0063] R_cold = 1 - R_hot

[0064] Note: This formula assumes that the heat loss of hot water and cold water when mixed is linear, and ignores other factors that may affect the mixing effect (such as heat loss in the pipeline, heat exchange during the mixing process, etc.);

[0065] The controller receives the user's preset water temperature T_target;

[0066] The controller reads the water temperature T_hot and T_cold in the hot water storage module and cold water storage module;

[0067] The controller calculates the mixing ratio R_hot and R_cold using the above formula;

[0068] The controller sends a control signal to the mixing unit, instructing the mixing unit to draw the corresponding amount of water from the hot water storage module and the cold water storage module according to the calculated mixing ratio;

[0069] The calibration module, when the mixing unit mixes the water temperature to the preset water temperature, transmits the water to the calibration module, which is responsible for further detection and calibration of the water temperature output by the mixing unit, to ensure that the output water temperature is consistent with the user's preset water temperature. When the mixing unit completes the mixing and outputs the water to the calibration module, the calibration module starts to work and detects the water temperature. If the detected water temperature is consistent with the user's preset water temperature or the deviation is within the preset allowable range, the next step is performed; if the deviation exceeds the allowable range, calibration is performed. When the water temperature deviates, fine-tune the water by heating or cooling;

[0070] The calibration module uses the following algorithm formula:

[0071] The calibration module receives water from the mixing unit and measures the actual water temperature T_actual using a temperature sensor;

[0072] The calibration module compares T_actual with the user's preset water temperature T_target;

[0073] If |T_actual - T_target| <= T_tolerance (where T_tolerance is the preset allowable temperature deviation range), the calibration module considers the water temperature to be up to standard and transmits the water to the output unit;

[0074] If |T_actual - T_target| > T_tolerance, the calibration module will start the heating or cooling device (depending on whether T_actual is higher or lower than T_target) to fine-tune the water temperature until the water temperature is up to standard. Embodiment 2

[0075] The cold and hot water temperature control system provided in Embodiment 1 is further optimized. Specifically, as shown in FIG. 1 and FIG. 4, the output unit, when the calibration module completes the water temperature calibration and transmits the water to the output unit, opens the output channel through the output unit to make the water flow smoothly.

[0076] Further, as shown in FIG. 1 and FIG. 4, the backflow unit is responsible for pumping the reserved water in the output unit back to the mixing unit for re-mixing when the mixing unit is performing the mixing operation, so as to ensure that the water output at the beginning stage is close to the preset temperature, avoiding the problem that the water output at the beginning stage is cold water.

[0077] The backflow unit uses the following algorithm formula:

[0078] Before the mixing unit starts the mixing operation, the backflow unit pumps the reserved water in the output unit back;

[0079] The backflow unit re-joins the pumped water into the mixing unit;

[0080] The controller determines whether the water temperature in the mixing unit is close to the user's preset water temperature T target. If yes, the backflow operation is stopped; otherwise, the backflow operation is continued until the water temperature in the mixing unit is close to T target.

[0081] When the mixing unit is performing the mixing operation, if the water temperature in the output unit deviates greatly from the user's preset water temperature T target, the backflow unit can be started again to pump part of the water back and re-mix, so as to improve the accuracy and stability of the output water temperature.

[0082] Further, as shown in FIG. 1 and FIG. 2, the hot water storage module comprises:

[0083] The first storage unit is responsible for storing hot water and reducing heat loss through heat preservation measures;

[0084] The heating unit monitors the water temperature in real time through the temperature sensor, and when the water temperature is lower than the preset heating threshold, sends a signal to the heating unit through the controller. The heating unit heats according to the preset heating temperature and time, and stops heating when the water temperature reaches the preset value.

[0085] Further, as shown in FIG. 1 and FIG. 2, the cold water storage module comprises:

[0086] The second storage unit is responsible for storing cold water and slowing down the temperature rise through heat preservation measures;

[0087] The refrigeration unit monitors the water temperature in the second storage unit in real time through the temperature sensor, and when the water temperature is higher than the preset refrigeration threshold, sends a signal to the refrigeration unit through the controller. The refrigeration unit cools according to the preset refrigeration temperature and time, and stops cooling when the water temperature reaches the preset value. Embodiment 3

[0091] A recording unit responsible for recording user operation information such as preset water temperature values, operation time, etc., and allowing users to add notes. By providing a function for users to add notes, it is convenient for users to record purposes or matters needing attention, and allows users to query historical records for review or reference.

[0092] An automatic replenishment unit responsible for real-time detection of the water level in the first and second storage units; compares the detected water level with the preset threshold value to determine whether water needs to be replenished; if the water level is below the threshold value, the automatic replenishment unit will send a signal to the water source control valve to open the water source and start replenishing water; during the replenishment process, the water level is continuously monitored, and when the water level reaches the preset upper limit value, the water source control valve is closed and the replenishment is stopped.
