[0062] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0063] Example 1

[0064] This embodiment provides a temperature control method for a drinking water platform, which can be applied to drinking water platforms of different models. Figure 1 , the temperature control methods of the drinking water platform include:

[0065] S1. Determine whether the outlet water temperature exceeds a preset temperature range.

[0066] The preset temperature range can be 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 50 degrees.

[0067] If the outlet water temperature exceeds the preset temperature range, steps S2 and S3 are executed.

[0068] In an optional embodiment, step S1 includes:

[0069] The current water temperature is announced by voice to remind the user to stop drawing water.

[0070] 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.

[0071] S2: Stop water discharge.

[0072] S3. Adjust the temperature.

[0073] Wherein, step S3 comprises:

[0074] S31. Open the drain valve to drain water.

[0075] S32, determining the number of steps of the flow regulating 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.

[0076] In an optional embodiment, the number of steps of the flow control valve is determined according to the following formula:

[0077] B1=B-(Tmax0-Tmax)*k1-(T0-T1)*k2-(T-T2)*k3-(T-T3)*k4;

[0078] 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.

[0079] 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 in the heating tank of the drinking water platform needs to reach in advance, the water outlet of the heating tank is connected to the water inlet of the drinking water platform, the water in the heating tank is transmitted to the water inlet of the drinking water platform through the water outlet of the heating tank, and then transmitted to the water outlet of the drinking water platform through the water inlet of the drinking water platform. When the user takes water, it flows out from the water outlet of the drinking water platform.

[0080] This embodiment drains water through a drain valve and controls the water inlet by determining the number of steps of a flow regulating valve according to the water inlet temperature and a preset boiling point value, thereby adjusting the water outlet temperature and reducing the impact of other factors such as the environment on the water outlet temperature, thereby accurately controlling the water outlet temperature of the drinking water platform, maintaining a constant water outlet temperature, and improving the user experience. At the same time, the present invention reduces the dependence of the temperature control method on hardware equipment, can be applied to drinking water platforms of different models, reduces the process of re-exploring experience values, reduces R&D costs, and improves product compatibility.

[0081] In an alternative embodiment, see Figure 2 , after step S3, including:

[0082] S321, determining whether the temperature adjustment time is greater than a first preset time.

[0083] The first preset time is set according to the actual situation. For example, if the first preset time is 10 seconds, the drain valve is kept open for 10 seconds, and water is kept flowing in for 10 seconds according to the ratio of the steps of the flow regulating valve and the water flow.

[0084] If the temperature adjustment time is longer than the first preset time, step S322 is executed.

[0085] If the temperature adjustment time is less than or equal to the first preset time, return to step S3.

[0086] S322: Determine whether the difference between the outlet water temperature after temperature adjustment and the preset temperature is greater than or equal to a first threshold.

[0087] The preset temperature is the maximum value of the preset temperature range. The first threshold value is set according to actual needs.

[0088] If the difference is greater than or equal to the first threshold, return to step S3.

[0089] If the difference is less than the first threshold, step S323 is executed.

[0090] S323: Determine whether the difference is greater than or equal to a second threshold.

[0091] The second threshold is smaller than the first threshold. For example, if the first threshold is set to 10 degrees and the second threshold is smaller than 10 degrees, the second threshold can be set to 5 degrees.

[0092] If the difference is greater than or equal to the second threshold, execute step S324.

[0093] 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.

[0094] The first target number of steps can be set according to actual conditions, for example, the first target number of steps can be set to 10 steps.

[0095] If the difference is less than the second threshold, return to step S1.

[0096] See below Figure 3 Here are the temperature adjustment steps when the difference between the outlet water temperature and the preset temperature is greater than or equal to 10 degrees:

[0097] 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.

[0098] 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).

[0099] 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.

[0100] 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 second threshold, the second threshold is 5 degrees, and T is the preset temperature); if greater than or equal to, execute S335, otherwise, execute step S336.

[0101] 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.

[0102] 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.

[0103] S337, determine whether the water outlet temperature is lower than T+2 degrees, if not lower than T+2 degrees, execute step S338, otherwise execute step S339.

[0104] S338. Increase the number of steps of the flow control valve adjusted last time by 5 steps, and return to step S336.

[0105] S339, save the current water inlet temperature, boiling point value and the number of rotation steps of the current motor of the flow control valve, and set the flag of abnormal water outlet temperature to 1 to prompt the user to get water.

[0106] 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.

[0107] In an alternative embodiment, see Figure 4 , after step S3, including:

[0108] S341, determining whether the temperature adjustment time is greater than a second preset time.

[0109] The second preset time length is set according to actual conditions. For example, if the second preset time length is 10 seconds, the drain valve is kept open for 10 seconds, and water is kept flowing in for 10 seconds according to the ratio of the steps of the flow regulating valve and the water flow.

[0110] If the temperature adjustment time is longer than the second preset time, step S342 is executed.

[0111] If the temperature adjustment time is less than or equal to the second preset time, return to step S3.

[0112] S342: Determine whether the difference between the outlet water temperature after temperature adjustment and the preset temperature is greater than or equal to a third threshold.

[0113] The preset temperature is the maximum value of the preset temperature range. The third threshold value is set according to actual needs.

[0114] If the difference is less than the third threshold, return to step S1.

[0115] If the difference is greater than or equal to the third threshold, execute step S343.

[0116] S343, determining whether the temperature adjustment step is the first temperature adjustment step after water discharge.

[0117] The first temperature adjustment step after the water comes out is the first temperature adjustment operation performed by the drinking water platform after the user takes the water.

[0118] If it is the first temperature adjustment step after water comes out, return to step S3.

[0119] If it is not the first temperature adjustment step after water comes out, execute step S344.

[0120] S344, 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.

[0121] The first preset speed increase rate can be set according to actual needs. For example, the first preset speed increase rate can be set to increase by one step every two seconds.

[0122] See below Figure 5 Here are the temperature adjustment steps when the difference between the outlet water temperature and the preset temperature is greater than or equal to 2 degrees but less than 10 degrees:

[0123] S351. Determine whether the user continues to discharge water for more than 10 seconds (i.e., determine whether the temperature adjustment time is greater than the second preset time, which is 10 seconds). If it exceeds 10 seconds, execute step S353; if it does not exceed 10 seconds, execute step S352.

[0124] S352. Open the drain valve and continue draining water for 10 seconds.

[0125] S353: Determine whether the difference between the outlet water temperature and the preset temperature is less than 10 degrees; if it is greater than or equal to 10 degrees, execute Figure 3 If the temperature is less than 10 degrees, execute step S354.

[0126] Step S353 is mainly to prevent the situation where the difference between the outlet water temperature and the preset temperature is greater than or equal to 10 degrees due to environmental factors, thereby preventing the risk of scalding the user.

[0127] S354, determine whether the difference between the water outlet temperature and the preset temperature is less than 2 degrees. If so, execute step S355; if greater than or equal to 2 degrees, execute step S356.

[0128] S355, save the current water inlet temperature, boiling point value and the number of rotation steps of the current motor of the flow control valve, set the flag of abnormal water outlet temperature to 1, and prompt the user that water can be drawn normally.

[0129] S356. Determine whether it is the first temperature adjustment in the water taking process (i.e., determine whether the temperature adjustment step is the first temperature adjustment step after the water comes out). If so, execute step S357; if not, execute step S358.

[0130] S357. Calculate the number of rotation steps of the flow control valve motor according to the algorithm, and return to step S351.

[0131] S358. According to the number of steps calculated in the previous step, increase the temperature by 1 step every two seconds, and return to step S351 (i.e. increase the number of steps of the flow regulating valve according to the first preset growth rate, and let in water according to the ratio of the adjusted number of steps of the flow regulating valve to the water flow rate).

[0132] In this embodiment, if it is not the first temperature adjustment, the number of rotation steps of the flow control 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.

[0133] In an alternative embodiment, see Figure 6 , after step S3, including:

[0134] S361, determine whether the temperature adjustment time is greater than the third preset time. If the temperature adjustment time is greater than the third preset time, execute step S362.

[0135] If the temperature adjustment time is less than or equal to the third preset time, return to step S3.

[0136] The third preset time length is set according to actual conditions. For example, if the third preset time length is 10 seconds, the drain valve is kept open for 10 seconds, and water is kept flowing in for 10 seconds according to the ratio of the steps of the flow regulating valve and the water flow.

[0137] S362: Determine whether the difference between the outlet water temperature after temperature adjustment and the preset temperature is less than a fourth threshold; if the difference is greater than or equal to the fourth threshold, return to step S1. If the difference is less than the fourth threshold, execute step S363.

[0138] The preset temperature is the minimum value of the preset temperature range. The fourth threshold value is set according to actual needs.

[0139] S363, determine whether the temperature adjustment step is the first temperature adjustment step after the water comes out; if it is the first temperature adjustment step after the water comes out, return to step S3; if it is not the first temperature adjustment step after the water comes out, execute step S364.

[0140] The first temperature adjustment step after the water comes out is the first temperature adjustment operation performed by the drinking water platform after the user takes the water.

[0141] S364, reducing the number of steps of the flow regulating valve according to the second 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.

[0142] The second preset speed increase can be set according to actual needs. For example, the second preset speed increase can be set to decrease by one step every two seconds.

[0143] See below Figure 7 Here are the temperature adjustment steps when the difference between the outlet water temperature and the preset temperature is less than -2 degrees:

[0144] S371. Determine whether the user continues to discharge water for more than 10 seconds (i.e., determine whether the temperature adjustment time is greater than the third preset time, which is 10 seconds). If it exceeds 10 seconds, execute step S373; if it does not exceed 10 seconds, execute step S372.

[0145] S372. Open the drain valve and continue draining water for 10 seconds.

[0146] S373, determine whether the difference between the water outlet temperature and the preset temperature is less than -2 degrees; if it is greater than or equal to -2 degrees, execute S374; if it is less than -2 degrees, execute step S375.

[0147] S374, save the current water inlet temperature, boiling point value and the number of rotation steps of the current motor of the flow control valve, set the flag of abnormal water outlet temperature to 1, and prompt the user that water can be drawn normally.

[0148] S375. Determine whether it is the first temperature adjustment in the water taking process (i.e., determine whether the temperature adjustment step is the first temperature adjustment step after the water comes out). If so, execute step S376; if not, execute step S377.

[0149] S376. Calculate the number of rotation steps of the flow control valve motor according to the algorithm, and return to step S371.

[0150] S377. According to the number of steps calculated in the previous step, reduce the temperature by 1 step every two seconds, continue to adjust the temperature, and return to step S371 (i.e. reduce the number of steps of the flow regulating valve according to the second preset speed increase, and let in water according to the ratio of the adjusted number of steps of the flow regulating valve to the water flow).

[0151] In this embodiment, if it is not the first temperature adjustment, the number of rotation steps of the flow control valve motor is further reduced to prevent the outlet water temperature from being too low, thereby more accurately adjusting the outlet water temperature, making the outlet water temperature more constant, and improving the user experience.

[0152] In an optional embodiment, the temperature control method of the drinking water platform further includes:

[0153] S4. Periodically obtain the water inlet temperature. The period can be set according to the needs.

[0154] S5, 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 S6.

[0155] S6. Re-determine the new number of steps of the flow control valve according to the inlet water temperature and the preset boiling point value.

[0156] 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.

[0157] A specific example of a temperature control method for a drinking water platform is introduced below to further illustrate the temperature control method for the drinking water platform of this embodiment.

[0159] S81, perform initialization operation: the drinking water platform is powered on and starts working; the flow regulating valve is reset to zero, that is, the motor of the flow regulating valve finds the zero point, and the number of steps of the flow regulating valve is 0 at this time.

[0160] S82. Read the water inlet temperature and the boiling point value set by the user (ie, the preset boiling point value).

[0166] 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.

[0176] S884. Monitor the outlet and inlet water temperatures.

[0177] The hot water tank is a heating tank used to store hot water and output the hot water to the water outlet of the drinking water platform.

[0178] The drinking water platform uses the pressure of the internal air bag of the pressure barrel to drain and intake water.

[0179] S89, determine whether the inlet water temperature deviates from the initial temperature by more than two degrees (i.e., determine 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, return to step S85 and then return to step S884. If not, execute step S810.

[0180] S810, determine whether the actual outlet water temperature is more than two degrees higher than the preset temperature (T), if it is more than two degrees, execute step S811, if it is not more than two degrees, execute step S812.

[0181] S811, determine whether the water temperature exceeds T+10 degrees, if it exceeds, execute Figure 3 If the temperature adjustment step is not exceeded, execute Figure 5 The temperature adjustment steps.

[0182] S812: Determine whether the outlet water temperature is more than two degrees lower than T. If so, execute Figure 7 If the temperature is not exceeded, execute step S813.

[0183] S813, No need to adjust the number of steps for normal water flow.

[0184] S814: Determine whether the user continues to fetch water. If the user continues to fetch water, return to step S883; if the user does not continue to fetch water, execute step S815.

[0185] S815, stop discharging water, the display screen shows the hot tank temperature, and the procedure for solving the abnormal water outlet temperature of the drinking water platform is completed.
