[0056] When the gas water heater is turned on again after being turned off, the user usually reduces the water flow rate by adjusting the waterway stop valve to increase the outlet water temperature and meet the bathing needs.

[0057] However, due to the significant difference in the inlet water temperature between summer and winter (the inlet water temperature is higher in summer and lower in winter), this operation will result in inconsistent ranges of the outlet water temperature after restarting, thus affecting the user's bathing experience.

[0058] Moreover, the different ambient temperatures in winter and summer lead to different heat losses in the household water pipelines, which in turn results in different usage temperatures of the same outlet water temperature of the water heater at different ambient temperatures.

[0059] To solve the above technical problems in the prior art, the present application provides a temperature control method and device, which can accurately adjust the output heat according to the actual inlet water temperature, thereby maintaining a stable outlet water temperature, ensuring that the outlet water temperature after each start-up meets the user's requirements, and thus improving the user's usage experience.

[0060] Refer to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of a temperature control method for a water heater provided by the present application. The temperature control device of the water heater includes a water heater and a controller connected to each other. The controller is used to execute the steps of the method. The first embodiment may include the following steps:

[0061] Step 110: Obtain the inlet water temperature during the initial startup process of the water heater.

[0062] Wherein, the initial startup is the startup after the shutdown duration of the water heater exceeds a preset time threshold.

[0063] Step 120: Based on the inlet water temperature, determine the target load required for the water heater to start again.

[0064] Wherein, the time interval between the restart and the previous startup of the water heater is less than the time threshold.

[0065] Wherein, the time threshold can be artificially set and adjusted according to the actual situation.

[0066] In this embodiment, when the water heater is initially started, the inlet water temperature is automatically obtained, and the heating load required for the next start, i.e., the target load (such as combustion power or electric heating power), is dynamically adjusted according to the inlet water temperature. In this way, it can be ensured that whether in summer or winter, the water heater can accurately adjust the output heat according to the actual inlet water temperature, thereby maintaining a stable outlet water temperature, ensuring that the outlet water temperature after each start meets the user's requirements, and thus improving the user experience.

[0067] In some possible implementation manners, the inlet water temperature includes the inlet water temperature corresponding to each preset moment within a first preset time period after the initial start. Based on the inlet water temperature, determining the target load required for the water heater to restart, i.e., step 120, may include:

[0068] Step 121: Determine the average value of the inlet water temperature within the first preset time period.

[0069] Among them, the inlet water temperature can be recorded every T i time interval, and T i is a fixed value and can be any value in the range of 0.2 to 1 s.

[0070] For example, during the previous working process of the water heater, i.e., the initial start process, the inlet water temperature is recorded every T i time interval as T j , then the average value T pj of the inlet water temperature = (T j1 +T j2 …T jnt ) / n t , where n t is the number of times the temperature signal is obtained, and n t can be any integer value in the range of (5, 10).

[0071] Step 122: Select the target preset threshold to which the average value belongs from a preset threshold range - start load multiple mapping table.

[0072] Among them, the preset threshold range - start load multiple mapping table can be as shown in Table 1 below:

[0073] Table 1

[0074]

[0075] Among them, K is a natural number greater than 1, and K1 > K2 > K3 > K4 > K5.

[0076] Step 123: Use the start load multiple corresponding to the target preset threshold as the target start load multiple when the water heater restarts.

[0077] Assume that the average value of the inlet water temperature is 8°, then the target preset threshold value to which the average value of 8° belongs is (5°, 10°), and the corresponding K2 can be used as the target start-up load multiple when the water heater is restarted.

[0078] In some possible implementation manners, the target start-up load multiple is negatively correlated with the average value of the inlet water temperature.

[0079] For example, if the average value of the inlet water temperature is 21°, then the target preset threshold value to which the average value of 21° belongs is (25°, 30°), and the corresponding K5 can be used as the target start-up load multiple when the water heater is restarted.

[0080] Among them, the average value of the inlet water temperature of 21° is greater than the average value of the inlet water temperature of 8°, and K5 is less than K2, that is, the target start-up load multiple is negatively correlated with the average value of the inlet water temperature.

[0081] In this way, by determining different start-up load values required when the water heater is restarted through different inlet water temperatures, it can be ensured that the outlet water temperature used by the user after the water heater is restarted is consistent at different inlet water temperatures.

[0082] Step 124: Based on the target start-up load multiple and the preset rated load, obtain the target load required when the water heater is restarted.

[0083] In some embodiments, the target load can be calculated using the following formula 1:

[0084] L s = K * L z , formula 1.

[0085] Among them, L s is the target load, K is the target start-up load multiple, and L z is the preset rated load.

[0086] In some possible implementation manners, before the step of obtaining the target load required when the water heater is restarted based on the target start-up load multiple and the preset rated load, that is, before step 124, the method further includes:

[0087] Step 211: Obtain the inlet water flow rate of the water heater after the initial start-up is completed.

[0088] Step 212: Based on the current inlet water flow rate, the current inlet water temperature, the preset target temperature, and the target start-up load multiple, obtain the preset rated load.

[0089] In some embodiments, the preset rated load can be calculated using the following formula 2:

[0090] L z= K * F x *(W x - W i ), Formula 2.

[0091] Wherein, K is the target starting load multiple, greater than 1, F x is the current influent flow rate, W i is the current influent temperature, W x is the preset target temperature.

[0092] In this way, the target starting load multiple is larger than the preset rated load, which can enable more load to quickly increase the temperature rise of hot water and reduce the heating time of cold water.

[0093] In some possible implementation manners, after obtaining the target load required for the water heater to restart, the method further includes:

[0094] Step 311: Obtain the outlet water temperature after the water heater restarts with the target load.

[0095] Step 312: Determine whether the outlet water temperature is within a preset target temperature range.

[0096] Step 313: If the outlet water temperature is within the preset target temperature range, adjust the target load of the water heater to the preset rated load.

[0097] Wherein, the preset target temperature range can be W x - m, m is greater than 0.5 and is an integer multiple of 0.1.

[0098] In this way, when the temperature sensor monitors that the outlet water temperature after restarting with the target load reaches the preset target temperature range W x - m, then the target load of the water heater is restored to the preset rated load L z , By restoring the preset rated load in advance, it can ensure that the bathing temperature will not be too high, thus ensuring the user experience.

[0099] In addition, when the target load of the water heater is restored to the preset rated load L z after that, it enters the normal IPD adjustment mode of the water heater.

[0100] In some possible implementation manners, the water flow sensor detects the water flow rate at the water inlet in real time. When the passing water flow rate is greater than a preset flow threshold Q, the water flow signal is fed back to the controller so that the controller controls the water heater to start working again.

[0101] In some possible embodiments, the water heater is provided with a first water channel and a second water channel. Before determining the target load required for the water heater to restart based on the inlet water temperature, the method further includes:

[0102] Step 411: Obtain the average inlet water flow rate during the restart operation of the water heater within a second preset time period.

[0103] Among them, the inlet water flow rate can be recorded every T i time period, and T i is a fixed value and can be any value in the range of 0.2 to 1.

[0104] Step 412: Determine whether the average inlet water flow rate is greater than a preset flow threshold.

[0105] Among them, the preset flow threshold can be Q + n1.

[0106] For example, F x =(F x1 +F x2 +F x3 +...+F xnQ ) / n Q > Q + n1.

[0107] Among them, n Q is the number of times of obtaining the water flow rate signal and can be any integer value in the range of (5, 10). n1 is greater than 0.5 and is an integer multiple of 0.1.

[0108] Step 413: If the average inlet water flow rate is greater than the preset flow threshold, control the water heater to be in a working state where the first water channel is open and the second water channel is closed.

[0109] Step 414: If the average inlet water flow rate is less than or equal to the preset flow threshold, control the water heater to be in a working state where both the first water channel and the second water channel are open.

[0110] Combined with Figures 2 - 7, in some possible embodiments, the water heater 10 includes a pipeline assembly 100, a stop valve 200, and a pump body 300. The pipeline assembly 100 includes a water inlet pipe 110, an intermediate connecting pipe 120, and a water outlet pipe 130 that are connected in sequence. The intermediate connecting pipe 120 is provided with a first through hole 121 and a second through hole 122. The stop valve 200 is disposed at the top of the pipeline assembly 100 and is connected to the second through hole 122. The pump body 300 is disposed at the bottom of the pipeline assembly 100 and is connected to the pipeline assembly 100. The water inlet pipe 110, the first through hole 121, and the water outlet pipe 130 are connected in sequence to form a first water channel; the water inlet pipe 110, the second through hole 122, and the water outlet pipe 130 are connected in sequence to form a second water channel.

[0111] Based on this, the state of the second water channel can be controlled by controlling the start and stop of the stop valve 200. Exemplarily, refer to Figure 5 , when the stop valve 200 is opened, the second water channel is in a closed state; refer to Figure 6 , when the stop valve 200 is closed, the second water channel is in an open state.

[0112] In this way, when the average water inlet flow rate is greater than a preset flow threshold, the stop valve 200 is opened when the water heater 10 is restarted again. By reducing the water volume, the amount of cold water passing through the water heater 10 when restarted is reduced. After a small amount of cold water is mixed with the high-temperature hot water heated by the remaining temperature in the water tank, the minimum temperature of the hot water when restarted can be increased.

[0113] Refer to Figure 8 , in some embodiments, the water heater 10 may be provided with a first temperature sensor 400, a second temperature sensor 500, and a water flow sensor 600. Among them, the first temperature sensor 400 is used to detect the water inlet temperature, the second temperature sensor 500 is used to detect the water outlet temperature, and the water flow sensor 600 is used to detect the water inlet flow rate.

[0114] In some embodiments, the water heater 10 may further include a heat exchanger and a servo structure. The servo structure may be disposed at any position in the water path of the water heater 10 and includes a water inlet channel and a water outlet channel.

[0115] Based on the above embodiments, the temperature control method of the water heater 10 provided by the present application mainly includes the following:

[0116] 1) During the initial startup process of the water heater 10, the temperature sensor is used to detect and collect the water inlet temperature of the user in real time;

[0117] 2) After the water heater 10 is initially used and closed, the controller issues an instruction. After the stop valve 200 receives the instruction, it can control the opening and closing of the second water channel of the water path, thereby reducing the water flow rate when restarted.

[0118] 3) After the water heater 10 is restarted, according to the detection data of the water flow sensor 600 and the temperature sensor, the target start load multiple when the water heater 10 is restarted is determined, so as to quickly reach the required temperature.

[0119] Refer to Figure 9 and Figure 10 , it can be seen that different target start load multiples are adopted when the water heater 10 is restarted at different inlet water temperatures, which can improve the consistency of the outlet water temperature.

[0120] 4) After the water heater 10 reaches the set time, the controller issues an instruction, the stop valve 200 opens the second water channel, the water flow is increased to the maximum water flow of the user, and at the same time the load is restored to the preset rated load, and enters the conventional IPD adjustment mode of the water heater 10, and the temperature control of the restart of the water heater 10 ends.

[0121] Corresponding to the above temperature control method of the water heater, the present application also provides a temperature control device for a water heater. The temperature control device of the water heater includes a unit for executing the above temperature control method of the water heater, and the temperature control device of the water heater can be configured in terminals such as a desktop computer, a tablet computer, a laptop computer, etc.

Among them, the processor 111, the communication interface 112, and the memory 113 communicate with each other through the communication bus 114, and the memory 113 is used to store a computer program;
