[0071] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0072] Example 1

[0073] This embodiment provides a control method for a drinking water platform. Figure 1 , the control methods of the drinking water platform include:

[0074] S1. Determine whether the outlet water temperature exceeds a preset temperature range.

[0075] The preset temperature range is set according to user needs. For example, the preset temperature range can be set to be greater than or equal to 40 degrees and less than or equal to 55 degrees, or the preset temperature range can be set to be greater than or equal to 40 degrees and less than or equal to 60 degrees.

[0076] If the outlet water temperature exceeds the preset temperature range, steps S2 and S3 are executed.

[0077] In an optional embodiment, step S1 includes:

[0078] The current water temperature is announced by voice to remind the user to stop drawing water.

[0079] In this embodiment, the user is reminded to stop fetching water through voice announcement, so as to prevent the user from being scalded or fetching water with an undesirable outlet temperature, thereby improving the user's water fetching experience.

[0080] S2: Stop water discharge.

[0081] S3. Adjust the temperature.

[0082] Wherein, step S3 comprises:

[0083] S31, determining the number of steps of the flow control valve according to the inlet water temperature and the preset boiling point value, and letting in water in accordance with the ratio of the number of steps to the water flow rate.

[0084] In an optional embodiment, the number of steps of the flow control valve is determined according to the following formula:

[0085] B1=B-(Tmax0-Tmax)*k1-(T0-T1)*k2-(T-T2)*k3-(T-T3)*k4;

[0086] Among them, B1 is used to characterize the number of adjustment steps of the flow control valve; B is used to characterize the maximum number of steps of the flow control valve; Tmax0 is used to characterize the initial boiling point value; Tmax is used to characterize the preset boiling point value; T0 is used to characterize the initial water inlet temperature; T1 is used to characterize the water inlet temperature; T is used to characterize the preset temperature; T2 is used to characterize the median of the preset temperature range; T3 is used to characterize the outlet water temperature; k1 is the first constant coefficient, which is used to characterize the influence ratio of the change of the preset boiling point value on the number of adjustment steps of the flow control valve; k2 is the second constant coefficient, which is used to characterize the influence ratio of the change of the water inlet temperature on the number of adjustment steps of the flow control valve; k3 is the third constant coefficient, which is used to characterize the influence ratio of the deviation between the preset temperature and the median of the preset temperature range on the number of adjustment steps of the flow control valve; k4 is the fourth constant coefficient, which is used to characterize the influence ratio of the deviation between the outlet water temperature and the preset temperature on the number of adjustment steps of the flow control valve. k1, k2, k3 and k4 are all empirical values ​​explored by experiments.

[0087] Among them, the water inlet temperature is the temperature of the water in the water inlet of the drinking water platform. The water inlet temperature will change due to the influence of environmental factors, and eventually cause the water outlet temperature to change accordingly; the preset boiling point value is the target temperature that the water temperature needs to reach after a preset heating.

[0088] S32, controlling the heating power of the first rapid heating module in the drinking water platform according to the cold water mixing temperature, the preset boiling point value, the water temperature after one heating, and the water inlet flow of the first rapid heating module, so that the water temperature after one heating reaches the preset boiling point value.

[0089] The water inlet of the first rapid heating module is connected to the first water outlet of the flow regulating valve and the cold water outlet of the heat exchanger respectively, and the cold water mixing temperature is the temperature of the water in the water inlet of the first rapid heating module.

[0090] Step S3 includes:

[0091] S4. Determine whether the difference between the preset temperature and the outlet water temperature after temperature adjustment is greater than or equal to a first threshold.

[0092] The preset temperature is the target value of the outlet water temperature set by the user. The first threshold is set according to actual needs. For example, if the first threshold is set to 1 degree.

[0093] If the difference is greater than or equal to the first threshold, step S5 is executed.

[0094] If the difference is less than the first threshold, return to step S3.

[0095] S5. If the difference is greater than or equal to the first threshold, the heating power of the second rapid heating module in the drinking water platform is controlled according to the water temperature after heat exchange, the outlet water temperature and the preset temperature so that the outlet water temperature reaches the preset temperature.

[0096] Among them, the water inlet of the second rapid heating module is connected to the hot water outlet of the heat exchanger; the water temperature after heat exchange is the water temperature in the hot water outlet of the heat exchanger; the water outlet temperature is the water temperature in the water outlet of the second rapid heating module.

[0097] At this time, the outlet water temperature after temperature adjustment is lower than the preset temperature, and secondary heating is performed through the second rapid heating module to increase the outlet water temperature.

[0098] In this embodiment, through the joint temperature adjustment of the first quick heating module, the second quick heating module and the heat exchanger, the dependence of the outlet water temperature on the system can be reduced, and the influence of factors such as differences in components (heat exchangers), differences in water flow rates, changes in ambient temperature, and a decrease in the efficiency of the heat exchanger after a certain period of heat exchange is reduced, thereby having a greater compensation effect on the outlet water temperature.

[0099] This embodiment controls the water inlet by determining the number of steps of the flow regulating valve according to the water inlet temperature and the preset boiling point value, performs primary heating through the first rapid heating module, and performs secondary heating on the water temperature after heat exchange through the second rapid heating module. Combined with the drainage of the drain valve, the outlet water temperature can be quickly and accurately adjusted, and the influence of other factors such as the environment on the outlet water temperature can be reduced, so as to accurately control the outlet water temperature of the drinking water platform, keep the outlet water temperature constant, and improve the user experience. At the same time, the present invention solves the problem that the first cup of water is too cold, reduces the dependence of the control method on hardware equipment, can be applied to components of drinking water platforms of different models (such as heat exchangers), has greater compensation for the outlet water temperature, reduces the process of re-exploring the experience value, reduces R&D costs, and improves product compatibility.

[0100] In an alternative embodiment, referring to Figure 2 , step S3 further includes:

[0101] S33, open the drain valve to drain water.

[0102] Wherein, step S33 may be performed before step S31.

[0103] Step S3 includes:

[0104] S321, determining whether the temperature adjustment time is greater than a first preset time.

[0105] Among them, the first preset time is set according to the actual situation. For example, the first preset time is 10 seconds, that is, the drain valve is kept open for 10 seconds, and water is kept in for 10 seconds according to the ratio of the steps of the flow regulating valve and the water flow.

[0106] If the temperature adjustment time is longer than the first preset time, step S322 is executed.

[0107] If the temperature adjustment time is less than or equal to the first preset time, return to step S3.

[0108] S322: Determine whether the difference between the outlet water temperature after temperature adjustment and the preset temperature is greater than or equal to a second threshold.

[0109] The preset temperature is the target value of the outlet water temperature set by the user. The second threshold is set according to actual needs.

[0110] If the difference is greater than or equal to the second threshold, return to step S3.

[0111] If the difference is less than the second threshold, execute step S323.

[0112] S323: Determine whether the difference is greater than or equal to a third threshold.

[0113] The third threshold is less than the second threshold. For example, if the second threshold is set to 10 degrees, the third threshold is less than 10 degrees, and the third threshold can be set to 5 degrees. The second threshold can be determined by the upper limit of the outlet water temperature, for example, it can be set to the difference between the upper limit of the outlet water temperature (e.g., 60 degrees) and the preset temperature.

[0114] If the difference is greater than or equal to the third threshold, execute step S324.

[0115] S324, increasing the number of steps of the flow regulating valve by a first target number of steps, and letting in water according to the sum of the number of steps of the flow regulating valve and the first target number of steps.

[0116] The first target number of steps is set according to actual conditions, for example, the first target number of steps is set to 10 steps.

[0117] If the difference is less than the third threshold, return to step S1.

[0118] Here, there is no restriction on the order of step S321 and step S4, step S322 and step S4, and step S323 and step S4.

[0119] Refer to the following Figure 3 The temperature adjustment steps are introduced when the difference between the outlet water temperature and the preset temperature is greater than or equal to the second threshold value (that is, the outlet water temperature exceeds the outlet water temperature upper limit):

[0120] S331. Close the water outlet solenoid valve, stop the water outlet, and give a voice message that the temperature is too high and asks you to get water later.

[0121] S332. Calculate the number of rotation steps of the flow control valve motor according to the algorithm, and open the drain solenoid valve to adjust the temperature (i.e., open the drain valve to drain water, and determine the number of steps of the flow control valve according to the inlet water temperature and the preset boiling point value, and let in water according to the ratio of the number of steps to the water flow).

[0122] S333, determine whether the temperature adjustment time is greater than 10 seconds (the first preset time); if greater, execute S334; if less than or equal to, return to S332.

[0123] S334, determine whether the water temperature is lower than T+5 degrees (i.e., determine whether the difference is greater than or equal to the third threshold, the third threshold is 5 degrees, and T is the preset temperature); if greater than or equal to, execute S335, otherwise, execute step S336.

[0124] S335, add 10 steps to the number of steps calculated in the previous step (that is, increase the number of steps of the flow regulating valve by the first target number of steps, which is 10 steps, and let in water according to the sum of the number of steps of the flow regulating valve and the first target number of steps), and continue to open the drain solenoid valve to drain for 10 seconds, and return to step S334.

[0125] S336. Let water in according to the number of steps of the flow control valve calculated last time, and continue to open the drain solenoid valve to drain for 10 seconds.

[0126] S337, determine whether the water outlet temperature is lower than T+1 degrees, if not lower than T+1 degrees, execute step S338, otherwise execute step S339.

[0127] S338. Increase the number of steps of the flow control valve adjusted last time by 5 steps, and return to step S336.

[0128] S339: Prompt the user to get water.

[0129] In this embodiment, after a set time, it is determined whether the outlet water temperature is within the preset temperature range. By correcting it under different conditions, the outlet water temperature is made more constant, reducing the influence of the water inlet flow rate, water outlet flow rate, ambient temperature, etc. on the outlet water temperature, thereby improving the user experience.

[0130] In an alternative embodiment, referring to Figure 4 , after step S3, including:

[0131] S341. Determine whether the difference between the outlet water temperature after temperature adjustment and the preset temperature is greater than or equal to a fourth threshold.

[0132] The preset temperature is the target value of the outlet water temperature set by the user. The fourth threshold value is set according to actual needs.

[0133] If the difference is less than the fourth threshold, return to step S1.

[0134] If the difference is greater than or equal to the fourth threshold, step S342 is executed.

[0135] S342, increasing the number of steps of the flow regulating valve according to a first preset speed increase, and letting in water according to the ratio of the adjusted number of steps of the flow regulating valve to the water flow rate.

[0136] The first preset speed increase can be set according to actual needs. For example, the first preset speed increase can be set to increase by one step every two seconds.

[0137] Refer to the following Figure 5 The following describes the temperature adjustment steps when the difference between the outlet water temperature and the preset temperature is greater than or equal to 1 degree but less than the second threshold value (i.e. the outlet water temperature does not exceed the outlet water temperature upper limit):

[0138] S351. Determine whether the difference between the water outlet temperature and the preset temperature is less than 5 degrees. If it is greater than or equal to 5 degrees, execute step S352; if it is less than 5 degrees, execute step S353.

[0139] S352: Determine whether the difference between the water outlet temperature and the preset temperature is less than a second threshold; if it is greater than or equal to the second threshold, execute Figure 3 If the temperature is less than the second threshold, execute step S354.

[0140] Step S352 is mainly to prevent the situation in which the difference between the outlet water temperature and the preset temperature is greater than or equal to the second threshold due to environmental factors, thereby preventing the risk of scalding the user.

[0141] S353, according to the number of steps calculated in the previous step, increase one step every two seconds, continue to adjust the temperature, and execute step S355.

[0142] S354. Calculate the number of rotation steps of the flow control valve motor according to the algorithm, and execute step S356.

[0143] S355, determine whether the user continues to fetch water, if the user continues to fetch water, execute step S356, if the user does not continue to fetch water, return to step S351.

[0144] S356. Determine whether the difference between the water outlet temperature and the preset temperature is less than 1 degree. If so, execute step S357; if greater than or equal to 1 degree, return to step S351.

[0145] S357, prompting the user that water can be obtained normally.

[0146] Here, there is no restriction on the order of step S351 and step S4, step S352 and step S4, and step S356 and step S4.

[0147] In this embodiment, the number of rotation steps of the flow regulating valve motor is further increased to prevent the outlet water temperature from being too high, thereby more accurately adjusting the outlet water temperature, making the outlet water temperature more constant, and improving the user experience.

[0148] In an optional embodiment, the control method further includes:

[0149] S6. Periodically obtain the water inlet temperature. The period can be set according to the needs.

[0150] S7, judging whether the temperature difference between the inlet water temperature and the inlet water temperature corresponding to the number of steps of the flow control valve exceeds a preset threshold. If so, executing step S8.

[0151] S8. Re-determine the new number of steps of the flow control valve according to the inlet water temperature and the preset boiling point value.

[0152] In this embodiment, since the inlet water temperature will change with the change of ambient temperature, the inlet water temperature is not constant. The difference between the inlet water temperature and the inlet water temperature corresponding to the step number of the flow control valve is monitored. If the difference is too large, the new step number of the flow control valve is re-determined to reduce the impact of ambient temperature on the inlet water temperature, thereby reducing the impact of ambient temperature on the outlet water temperature, thereby achieving the effect of precise temperature control.

[0153] In an optional embodiment, the control method further includes:

[0154] When the user has not taken water for a preset continuous period of time, the drain valve is opened to drain water.
