[0061] The heat carried by the second tube of the heat exchanger 32 is exchanged to the first tube of the heat exchanger 32 to increase the temperature of the water flowing through the first tube of the heat exchanger 32, thereby achieving heat exchange.

[0065] It is understandable that the hot tank 41 is provided with an exhaust hole 42 , and the hot tank 41 exhausts excess gas inside the hot tank 41 through the exhaust hole 42 .

[0068] Optionally, the heating module 500 uses a thick film heater 51. The thick film heater 51 is usually a heating element formed by making a heating resistor material or the like on a substrate using thick film technology. The thick film heater 51 has the characteristics of rapid heating, high thermal efficiency, stable performance, and long service life, and is widely used in some equipment that requires rapid heating and precise temperature control.

[0072] Smart devices include, but are not limited to: various personal computers, laptops, smart phones, tablets, portable wearable devices, smart gateways, and servers.

[0073] The present invention is described in detail below through specific embodiments.

[0074] See also Figure 2 As shown, Figure 2 A flow chart of a water supply device drainage control method provided in an embodiment of the present invention, wherein the method is used to control a water supply device, wherein the water supply device comprises: a heat exchange module 300, a heat storage module 400, a heating module 500 and a water outlet module 200;

[0075] The method comprises:

[0076] S1: Acquire a drainage signal, wherein the drainage signal carries a target temperature and a desired flow rate;

[0077] The water discharge signal is a signal for discharging water from the water discharge module 200 .

[0078] The target temperature is the temperature of water discharged from the water outlet module 200 that the user wants.

[0079] The expected flow rate is the flow rate of water discharged from the water outlet module 200 that the user wants.

[0080] Specifically, the user can trigger the drainage signal through the button on the water supply device, the user can also input the drainage signal through the touch screen on the water supply device, the user can also input the drainage signal through the client connected to the communication with the water supply device, and the user can also send the drainage signal to the server through a third-party application, and the server will send the drainage signal to the program file that implements this application.

[0081] The client may include but is not limited to: various personal computers, laptops, smart phones, tablet computers, portable wearable devices.

[0082] The server may be a server.

[0083] S2: In response to the drainage signal, obtaining the normal water temperature of the water supply device, the heat storage data of the heat storage module 400, the heat exchange configuration of the heat exchange module 300 and the heating configuration of the heating module 500;

[0084] Specifically, when the drainage signal is obtained, the energy data stored in the heat storage module 400 in real time is obtained as heat storage data, and the heat exchange configuration of the heat exchange module 300 and the heating configuration of the heating module 500 can be obtained from the preset storage space.

[0085] The normal water temperature of the water supply device is the temperature of the water input into the water supply device through the water inlet 80. The temperature of the water input into the water supply device can be detected by installing a temperature detection sensor at the water inlet 80. When the drainage signal is obtained, the real-time temperature detected by the temperature detection sensor is used as the normal water temperature of the water supply device.

[0086] The heat exchange configuration of the heat exchange module 300 includes: corresponding relationship data of the flow rate of the second tube of the heat exchanger 32 , the flow rate of the first tube of the heat exchanger 32 , and the temperature of the water in the hot tank 41 .

[0089] Optionally, when the water outlet module 200 takes the target temperature as the primary target and the expected flow rate as the secondary target, a table lookup method is used to determine the drainage control data based on the normal water temperature, the target temperature, the expected flow rate, the heat storage data, the heat exchange configuration and the heating configuration. It can be understood that the data in the table used by the table lookup method can be obtained through limited experiments and will not be elaborated here.

[0090] The water outlet module 200 takes the target temperature as the primary target and the expected flow rate as the secondary target, that is, it prioritizes ensuring that the temperature of the discharged water is equal to the target temperature. When the temperature of the discharged water cannot be guaranteed to be equal to the target temperature, the actual water outlet flow rate of the water outlet module 200 is reduced (which is lower than the expected flow rate at this time) so that the temperature of the water discharged by the water outlet module 200 is equal to or close to the target temperature.

[0091] Optionally, the drainage control data includes: control data of each module (heat exchange module 300, heat storage module 400, heating module 500 and water outlet module 200).

[0092] S4: Controlling the water supply device to drain water according to the drainage control data.

[0093] Specifically, according to the control data of each module of the drainage control data, one or more modules among the heat exchange module 300, the heat storage module 400, the heating module 500 and the water outlet module 200 are controlled to drain water, so as to realize drainage of the water outlet module 200 with the target temperature as the primary target and the expected flow rate as the secondary target based on the heat energy stored in the heat storage module 400 and / or the heat energy generated by heating of the heating module 500.

[0094] It can be understood that the water discharged in step S4 can be any one of room temperature water, warm water and boiling water.

[0095] It can be understood that the present application uses heat exchange and instant heating of the heating module 500 to ensure that the hot water discharged by the water supply device each time is freshly heated water, which meets the user's demand for healthy drinking water.

[0096] This embodiment can accurately obtain the heat storage data of the heat storage module 400, the heat exchange configuration of the heat exchange module 300, and the heating configuration of the heating module 500 according to the drainage signal carrying the target temperature and the expected flow rate, and then determine the scientific and reasonable drainage control data. According to these drainage control data, the drainage of each module of the water supply device is accurately controlled, which not only greatly improves the output of hot water, ensures that there is sufficient hot water supply under different needs, but also can flexibly meet the diverse needs of users for hot water of different temperatures.

[0097] See also Figure 3 As shown, in one embodiment, the method further includes:

[0098] S51: Obtain water use habit data;

[0099] Specifically, the water use habit data may be obtained from a preset storage space, or may be obtained from a client or a server.

[0100] It is understandable that water usage habit data may be obtained at intervals, for example, at 4 a.m. every day.

[0101] Water use habit data describes the corresponding relationship between water use time, water use amount and water use temperature.

[0102] S52: determining a heat storage mode according to the water use habit data;

[0103] Optionally, a table lookup method is used to determine the heat storage mode based on the water usage habit data.

[0104] Optionally, the water use habit data is input into a preset pattern prediction model for classification prediction, a vector element with the largest value is extracted from the predicted vector, and the classification category corresponding to the extracted vector element is used as the heat storage pattern.

[0105] The preset pattern prediction model is a pre-trained multi-classification model. The model structure and model training method of the pattern prediction model can be selected from the existing technology and are not limited here.

[0106] S53 : According to the heat storage mode, the water heated by the heating module 500 is stored in the heat storage module 400 .

[0107] Specifically, according to the heat storage mode, the heating module 500 is controlled to heat, and the water heated by the heating module 500 is transported to the heat storage tank 41 of the heat storage module 400 to store thermal energy in the heat storage tank 41 .

[0108] It is understandable that the heat storage mode is determined once at the start time of each interval period, and then the determined heat storage mode is adopted during the interval period to store the water heated by the heating module 500 in the heat storage module 400 .

[0109] This embodiment adopts a heat storage mode determined according to the water use habit data to store the water heated by the heating module 500 in the heat storage module 400, so that the heat storage meets the user's water use habits, thereby achieving the purpose of energy saving while improving user satisfaction.

[0110] In one embodiment, the step of determining drainage control data according to the normal water temperature, the target temperature, the expected flow rate, the heat storage data, the heat exchange configuration and the heating configuration includes:

[0111] S31: determining whether water at the target temperature can be discharged at the expected flow rate according to the normal water temperature, the heat storage data and the heat exchange configuration, and obtaining a first result;

[0112] Optionally, a table lookup method is used to determine whether water of the target temperature can be discharged at the expected flow rate based on the normal water temperature, the heat storage data and the heat exchange configuration, and the result obtained by the table lookup is used as the first result.

[0113] Optionally, the normal water temperature, the heat storage data, the heat exchange configuration, the target temperature, and the expected flow rate are input into a preset discriminant model for classification prediction, and the classification category corresponding to the vector element with the largest median value of the predicted vector is taken as the first result.

[0114] The preset discriminant model is a pre-trained binary classification model. The model structure and model training method of the discriminant model can be selected from the existing technology and will not be described in detail here.

[0115] S32: If the first result is yes, determining the drainage control data according to the normal water temperature, the target temperature, the expected flow rate, the heat storage data, and the heat exchange configuration;

[0116] Specifically, if the first result is yes, it means that by only using the thermal energy in the heat storage module 400, the water at the target temperature can be discharged at the expected flow rate. When the water outlet module 200 meets the target temperature and the expected flow rate, the drainage control data is determined by a table lookup method based on the normal water temperature, the target temperature, the expected flow rate, the heat storage data, and the heat exchange configuration. It can be understood that the expected flow rate at this time is the target flow rate for water to be discharged from the water outlet module.

[0117] S33: If the first result is no, determining the drainage control data according to the normal water temperature, the target temperature, the expected flow rate, the heat storage data, the heat exchange configuration and the heating configuration.

[0118] Specifically, if the first result is no, it means that only the heat energy in the heat storage module 400 cannot discharge the water of the target temperature at the expected flow rate. On the premise that the water outlet module 200 meets the target temperature as the primary goal, the heat storage module 400 and the heating module 500 are used in combination to determine the drainage control data according to the normal water temperature, the target temperature, the expected flow rate, the heat storage data, the heat exchange configuration and the heating configuration.

[0119] This embodiment first determines whether water of the target temperature can be discharged at the expected flow rate based on the normal water temperature, heat storage data, and heat exchange configuration to obtain a first result. If the result is yes, the drainage control data is determined based on the relevant data. If not, the drainage control data is determined in combination with the heating configuration, so as to achieve precise control of water temperature and water flow.

[0120] In one embodiment, if the first result is no, the step of determining the drainage control data according to the normal water temperature, the target temperature, the expected flow rate, the heat storage data, the heat exchange configuration and the heating configuration includes:

[0121] S331: If the first result is no, determining whether the water at the target temperature can be discharged at the expected flow rate according to the normal water temperature, the heat storage data, the heat exchange configuration and the heating configuration, to obtain a second result;

[0122] Specifically, if the first result is no, it means that only the thermal energy in the heat storage module 400 cannot discharge the water of the target temperature at the expected flow rate.

[0123] Optionally, a table lookup method is used to determine whether water of the target temperature can be discharged at the expected flow rate based on the normal water temperature, the heat storage data, the heat exchange configuration and the heating configuration, and the result obtained from the table lookup is used as the first result.

[0124] Optionally, the normal water temperature, the normal water temperature, the heat storage data, the heat exchange configuration and the heating configuration, the target temperature, and the expected flow rate are input into a preset discriminant model for classification prediction, and the classification category corresponding to the vector element with the largest median value of the predicted vector is taken as the second result.

[0125] S332: If the second result is yes, determining the drainage control data according to the normal water temperature, the target temperature, the expected flow rate, the heat storage data, the heat exchange configuration and the heating configuration;

[0126] Specifically, if the second result is yes, it means that the cooperation between the heat storage module 400 and the heating module 500 can output water of the target temperature at the expected flow rate. Therefore, when the water outlet module 200 meets the target temperature and the expected flow rate, the drainage control data is determined by a table lookup method based on the normal water temperature, the target temperature, the expected flow rate, the heat storage data, the heat exchange configuration and the heating configuration. It can be understood that the expected flow rate at this time is the target flow rate for water to be discharged from the water outlet module.

[0127] S333: If the second result is no, then based on the target temperature being the temperature target, the adjusted flow rate is determined according to the normal water temperature, the heat storage data, the heat exchange configuration and the heating configuration, and the drainage control data is determined according to the normal water temperature, the target temperature, the adjusted flow rate, the heat storage data, the heat exchange configuration and the heating configuration.

[0128] Specifically, if the second result is no, it means that the cooperation of the heat storage module 400 and the heating module 500 cannot output water of the target temperature at the expected flow rate. Therefore, first, based on the target temperature as the temperature target, according to the normal water temperature, the heat storage data, the heat exchange configuration and the heating configuration, the adjusted flow rate is determined by using a table lookup method or a preset adjustment flow rate calculation formula. Then, based on the goal of discharging the target temperature at the adjusted flow rate, according to the normal water temperature, the target temperature, the adjusted flow rate, the heat storage data, the heat exchange configuration and the heating configuration, the drainage control data is determined by using a table lookup method. It can be understood that at this time, the adjusted flow rate is the target flow rate for discharging water from the water outlet module.

[0129] The preset adjustment flow rate calculation formula can be obtained based on the linear fitting of historical data.

[0130] In this embodiment, a first result is obtained by first judging whether water of the target temperature can be discharged at the expected flow rate based on the normal water temperature, and if not, a second result is obtained by combining the heating configuration. If so, the drainage control data is determined, and if not, the drainage control data is determined after adjusting the flow rate based on the target temperature. This enables fine regulation and accurate calculation of water temperature, flow rate, etc., ensuring that a suitable drainage control strategy can be found in different situations, making the system run more stably and efficiently, and at the same time, flexibly adjusting according to actual conditions, taking various factors into consideration to achieve the optimal drainage effect, and being able to reasonably use the heating configuration to meet needs, thereby ensuring the effective operation of the water supply device and the rational use of resources.

[0131] In one embodiment, the step of controlling the water supply device to drain water according to the drainage control data includes:

[0135] S42: generating temperature compensation data according to the outlet water temperature and the target temperature;

[0136] Optionally, the water outlet temperature and the target temperature are input into a preset compensation formula to calculate temperature compensation data.

[0137] It can be understood that the preset compensation formula is obtained by linear fitting based on multiple sets of historical water outlet temperatures and target temperatures.

[0138] S43: Update the drainage control data according to the temperature compensation data.

[0139] Specifically, according to the temperature compensation data, the compensation data of each module is determined by using a table lookup method, and the drainage control data is updated according to the supplementary data of each module.

[0140] After the water supply device has been used for a period of time, the internal components of the water supply device age, resulting in deviations in the control target and the time effect of the control, which ultimately makes it difficult for the water discharged from the water outlet module 200 to reach the target temperature. In order to solve this problem, the present embodiment obtains the outlet water temperature of the water outlet module 200 and compares it with the target temperature to generate temperature compensation data, and then uses the temperature compensation data to update the drainage control data to compensate for the deviations in the control target and the time effect of the control caused by the aging of the internal components of the water supply device. This can make the drainage control more precise and adapt to the actual temperature conditions, help to achieve accurate regulation and stable control of the outlet water temperature, and improve the performance and effect of the entire system.

[0141] In one embodiment, after the step of obtaining the outlet water temperature of the water outlet module 200, the method further includes:

[0142] S44: generating supplementary heating data according to the discharge flow rate, the outlet water temperature and the target temperature in the drainage control data;

[0143] Specifically, the discharge flow rate, the outlet water temperature and the target temperature in the drainage control data are input into a preset supplementary data calculation formula to obtain supplementary heating data.

[0144] It can be understood that the preset supplementary data calculation formula is obtained by linear fitting based on multiple sets of historical discharge flow rates, the outlet water temperature and the target temperature.

[0145] The supplementary heating data describes the heating power.

[0146] S45: controlling the water outlet module 200 according to the supplementary heating data to heat the water in the water outlet module 200.

[0147] Specifically, the water outlet module 200 is controlled according to the supplementary heating data to supplementally heat the water in the water outlet module 200, thereby making the water discharged from the water outlet module 200 equal to or very close to the target temperature.

[0148] This embodiment controls the water outlet module 200 according to the supplementary heating data to heat the water in the water outlet module 200, thereby realizing the use of the water outlet module 200 for supplementary heating before drainage, further realizing precise regulation and stable control of the outlet water temperature, and improving the performance and effect of the entire system.
