[0048] Figure 2 This illustration schematically shows a structural diagram of an on-board water supply system according to an embodiment of this application, such as... Figure 2 As shown, in one embodiment of this application, a vehicle-mounted water supply system is provided, which may include:

[0049] Cold water tank 100 is used to store cold water;

[0050] The warm water tank 200 includes a first inlet 210, a second inlet 220 and a first outlet 230. The first inlet 210 is connected to the cold water tank 100 through the cold water pump 300. The warm water tank 200 is used to receive cold water input from the cold water tank 100.

[0051] The heating device 400 includes a third water inlet 410 and a second water outlet 420. The second water outlet 420 is connected to the second water inlet 220. The third water inlet 410 is connected to the first water outlet 230 through a circulation pump 500. The heating device 400 is used to receive water input into the warm water tank 200 and to output heated water to the warm water tank 200.

[0052] Central controller 600, used for:

[0053] Acquire demand condition data and preset target mixing temperature, where demand condition data includes vehicle driving time and water output demand.

[0054] Based on the required operating conditions data and the target mixing temperature, determine whether the rated outlet water temperature of the heating device 400 matches the required operating conditions data.

[0055] If the rated outlet water temperature does not match the required operating conditions, adjust the actual outlet water temperature of the heating device 400 to match the required operating conditions.

[0056] The operating time of the heating device 400 and the operating time of the circulating pump 500 are controlled according to the actual outlet water temperature.

[0057] The vehicle-mounted water supply system provided in this embodiment is intelligently controlled by a central controller 600. The central controller 600 can be electrically or communicatively connected to the cold water pump 300, the heating device 400, and the circulation pump 500. The cold water stored in the cold water tank 100 is used to supply water to the warm water tank to replenish its volume. When the central controller 600 detects that the water level in the warm water tank 200 is below a certain threshold (i.e., the warm water tank 200 is short of water) through a water level detector built into the warm water tank 200 and electrically or communicatively connected to the central controller 600, the central controller 600 sends a corresponding command to the cold water pump 300, instructing the cold water pump 300 to draw cold water from the cold water tank 100 and input it into the warm water tank 200 through the first inlet 210. When the water level in the warm water tank 200 reaches a certain preset requirement and the water is sufficient, the central controller 600 sends a corresponding command to the cold water pump 300, and the cold water pump 300 stops working.

[0058] In one embodiment of this application, the system further includes a temperature detector, which is disposed inside the warm water tank 200 and connected to the central controller 600, for real-time detection of the water temperature inside the warm water tank 200. The central controller 600 is also used for:

[0059] Obtain the water temperature detected by the temperature detector;

[0060] Determine if the water temperature has reached the rated return water temperature;

[0061] When the water temperature is lower than the rated return water temperature, the circulating pump 500 is controlled to draw water from the warm water tank 200 and input it into the heating device 400.

[0062] When the water in the warm water tank 200 is lower than the set temperature, the circulation pump 500 starts, drawing water from the warm water tank 200 and pumping it into the heating device 400 for heating. This set temperature is the rated return water temperature. To ensure normal system operation, the rated return water temperature in the normal setting must be higher than the temperature of the room temperature cold water. Therefore, after the cold water in the cold water tank 100 is input into the warm water tank 200, the central controller 600 detects that the water temperature in the warm water tank 200 is lower than the rated return water temperature through a temperature detector built into the warm water tank 200 and electrically or communicatively connected to the central controller 600. The central controller then sends a command to the circulation pump 500, instructing it to start and draw out the cold water from the warm water tank 200. The cold water in the warm water tank 200 is then pumped from the first outlet 230 to the third inlet 410 of the heating device 400 for heating.

[0063] After the heating device 400 heats the cold water entering the heating device 400 to the rated outlet temperature, the central controller 600 issues a corresponding instruction, and the hot water in the heating device 400 is output from the second outlet 420 of the heating device 400 to the second inlet 220 of the warm water tank 200, and enters the warm water tank 200 to be stored as hot water to be mixed with cold water later. Similarly, if the temperature of the hot water stored in the warm water tank 200 drops below the rated return water temperature after cooling, the central controller 600 issues an instruction to the circulation pump 500 to start the circulation pump 500 and draw water out of the warm water tank 200. The water in the warm water tank 200 is then pumped from the first outlet 230 to the third inlet 410 of the heating device 400 to enter the heating device 400 for heating.

[0064] In order to reduce the energy consumption of the entire system and to reasonably control the working time of the heating device 400 and the circulating pump 500 without wasting excess energy, the central controller 600 intelligently controls the working time of the heating device 400 and the circulating pump 500 by acquiring the operating data.

[0065] Since the water supply system is vehicle-mounted, it must be able to provide sufficient quantity and temperature of water when the vehicle arrives at its destination. The central controller 600 first acquires demand data and a preset target mixing temperature. The demand data includes vehicle travel time and water demand. For example, if the vehicle needs to arrive after a one-hour journey and provide 20L of bath water at 38 degrees Celsius per person for 20 people, then the travel time is one hour, the water demand is 400L, and the preset target mixing temperature is 38 degrees Celsius. Based on the aforementioned vehicle travel time, water demand, and target mixing temperature, the central controller 600 determines whether the rated outlet temperature of the heating device 400 matches the demand data. In other words, it determines whether heating the water to the rated outlet temperature would result in energy waste, provided that sufficient quantity and temperature of water can be provided on time.

[0066] In one embodiment of this application, determining whether the rated outlet water temperature of the heating device 400 matches the required operating conditions data and the target mixing water temperature includes:

[0067] The theoretical mixing temperature is determined based on the demand condition data, rated outlet water temperature, target mixing water temperature, and rated cold water supply.

[0068] If the difference between the theoretical mixing temperature and the target mixing temperature is greater than the first threshold, it is determined that the rated outlet temperature does not match the required operating conditions.

[0069] If the difference between the theoretical mixing temperature and the target mixing temperature is less than or equal to the first threshold, the rated outlet temperature is determined to match the required operating conditions.

[0070] The theoretical mixing temperature is the temperature of the mixed water obtained after the water heated to the rated outlet temperature by the heating device 400 is mixed with the room-temperature cold water in the cold water tank 100. For example, if the rated cold water supply M1 is 1 ton / hour (i.e., the cold water tank can provide 1 ton of cold water per hour for mixing with hot water), the cold water temperature T1 is assumed to be room temperature (25 degrees Celsius), and the rated outlet temperature T2 is 90 degrees Celsius, and all the bathing water (water volume: M2 = 400L) provided by the water supply system after one hour is considered as water that has been heated to the rated outlet temperature by the heating device 400 and then mixed with cold water, releasing heat, then the calculation process for the theoretical mixing temperature T is as follows:

[0071] Q1 = M1(T-T1)

[0072] Q2 = M2(T2-T)

[0073] Q1 = Q2

[0074] Then we have:

[0075] That is, with a theoretical mixing temperature of 90 degrees Celsius, the temperature of the mixed water provided after one hour can reach 43.5 degrees Celsius.

[0076] After determining the theoretical mixing temperature, the central controller 600 judges whether the rated outlet temperature matches the required operating conditions based on the difference between the theoretical and target mixing temperatures. If the difference between the theoretical and target mixing temperatures exceeds a first threshold, it is determined that the rated outlet temperature does not match the required operating conditions. The specific value of the first threshold can be set according to the actual design needs of the water supply system, and this application does not impose any limitations on it. For example, if the first threshold is 2 degrees Celsius, and the target mixing temperature is 38 degrees Celsius, the difference between the theoretical and target mixing temperatures reaches 5.5 degrees Celsius, which exceeds the first threshold. This means the rated outlet temperature does not match the required operating conditions, and heating the water to the rated outlet temperature by the heating device 400 would result in energy waste. Therefore, the central controller 600 needs to adjust the actual outlet temperature of the heating device 400.

[0077] In one embodiment of this application, when the rated outlet water temperature does not match the required operating conditions, adjusting the actual outlet water temperature of the heating device 400 to match the required operating conditions includes:

[0078] Adjust the actual outlet water temperature according to the difference between the theoretical mixing temperature and the target mixing temperature until the difference between the actual outlet water temperature and the target mixing temperature does not exceed the first threshold.

[0079] When adjusting the actual outlet water temperature, it can be adjusted based on the difference between the theoretical mixing temperature and the target mixing temperature. If this difference is large, the difference between the actual outlet water temperature and the rated outlet water temperature can be set larger, and then the theoretical mixing temperature at the actual outlet water temperature can be calculated. If the difference between the mixing temperature determined by the actual outlet water temperature and the target mixing temperature is still greater than the first threshold, the actual outlet water temperature can be adjusted based on this difference until the difference between the mixing temperature corresponding to the actual outlet water temperature and the target mixing temperature does not exceed the first threshold. For example, if the actual outlet water temperature is adjusted to 75 degrees Celsius (2 = 75), and the rated cold water supply M1, the default cold water temperature T1, and the amount of shower water provided by the water supply system after one hour remain unchanged, then the corresponding mixing temperature T is:

[0080]

[0081] When the actual outlet water temperature is 75 degrees Celsius, the difference between the mixed water temperature and the target mixed water temperature (38 degrees Celsius) is less than the first threshold (2 degrees Celsius). In other words, the heating device 400 only needs to heat the water to 75 degrees Celsius to meet the water supply needs, without needing to heat it to 90 degrees Celsius.

[0082] After confirming the actual outlet water temperature, the central controller 600 determines the working time of the heating device 400 and the working time of the circulation pump 500 based on the actual outlet water temperature. For example, if the rated outlet water temperature is 90 degrees Celsius, and the actual outlet water temperature obtained through the above embodiment is 75 degrees Celsius, the central controller 600 can perform intelligent control to shorten the working time of the heating device 400 and the working time of the circulation pump 500 to reduce energy consumption.

[0083] Through the above technical solution, when using the heating device 400, the system uses the central controller to intelligently optimize and adjust the working time of the heating device 400 and the circulation pump 500, and monitors and controls the water temperature of the entire system in real time. This allows the heating device 400 to work intelligently during vehicle operation, and the water temperature in the hot water tank can reach the required operating conditions when the vehicle reaches its destination. Because the usage time of the heating device 400 and the circulation pump 500 is intelligently controlled by the central controller, the heat conversion efficiency of the heating device 400 is optimized, reducing energy consumption and improving the service life of the working parts.

[0084] In one embodiment of this application, a vehicle is provided, including the on-board water supply system described in the above embodiments.

[0085] In one embodiment of this application, a vehicle-mounted water supply method is provided, applied to the vehicle-mounted water supply system in the above embodiments, the method comprising:

[0086] Step S100: Obtain the required operating condition data and the preset target mixing temperature through the central controller 600. The required operating condition data includes the vehicle driving time and the required water output.

[0087] Step S200: The central controller 600 determines whether the rated outlet water temperature of the heating device 400 matches the required operating conditions data and the target mixing water temperature based on the required operating conditions data.

[0088] Step S300: When the rated outlet water temperature does not match the required operating conditions data, the central controller 600 adjusts the actual outlet water temperature of the heating device 400 so that the actual outlet water temperature matches the required operating conditions data.

[0089] Step S400: The central controller 600 controls the working time of the heating device 400 and the working time of the circulation pump 500 according to the actual outlet water temperature.

[0090] In one embodiment of this application, determining whether the rated outlet water temperature of the heating device 400 matches the required operating conditions data based on the target mixing water temperature includes:

[0091] The theoretical mixing temperature is determined based on the demand condition data, rated outlet water temperature, target mixing water temperature, and rated cold water supply.

[0092] If the difference between the theoretical mixing temperature and the target mixing temperature is greater than the first threshold, it is determined that the rated outlet temperature does not match the required operating conditions.

[0093] If the difference between the theoretical mixing temperature and the target mixing temperature is less than or equal to the first threshold, the rated outlet temperature is determined to match the required operating conditions.

[0094] In one embodiment of this application, when the rated outlet water temperature does not match the required operating conditions, adjusting the actual outlet water temperature of the heating device 400 to match the required operating conditions includes:

[0095] Adjust the actual outlet water temperature according to the difference between the theoretical mixing temperature and the target mixing temperature until the difference between the actual outlet water temperature and the target mixing temperature does not exceed the first threshold.

[0096] In one embodiment of this application, the system further includes a temperature detector, which is disposed inside the warm water tank 200 and connected to the central controller 600, for real-time detection of the water temperature inside the warm water tank 200. The method further includes:

[0097] The water temperature detected by the temperature sensor is obtained through the central controller 600;

[0098] The central controller 600 determines whether the water temperature has reached the rated return water temperature.

[0099] When the water temperature is lower than the rated return water temperature, the central controller 600 controls the circulation pump 500 to draw water from the warm water tank 200 and input it into the heating device 400.

[0100] The vehicle-mounted water supply method in the above embodiments optimizes and adjusts the working time of the heating device 400 and the circulation pump 500 through the central controller 600, and monitors and controls the water temperature of the entire system in real time. This enables the heating device 400 to work intelligently during vehicle operation, and ensures that the water temperature in the hot water tank reaches the required operating conditions when the vehicle reaches its destination. Because the usage time of the heating device 400 and the circulation pump 500 is intelligently controlled by the central controller, the heat conversion efficiency of the heating device 400 is optimized, reducing energy consumption and improving the service life of the working components.
