Description

[Technical Field]

[0001] This invention relates to the field of household appliance technology, and in particular to a heating control method, device, water dispenser, and storage medium. [Background Technology]

[0002] Currently, instant hot water dispensers on the market require a large heating power to achieve their instant hot water function. However, when the instant hot water dispenser is in different regions or at different times, voltage fluctuations will cause fluctuations in heating power. If the fluctuations are large and the heating power is too high, the instant hot water dispenser is prone to producing a lot of water vapor during the heating process, which poses a safety hazard. If the fluctuations are large and the heating power is too low, the water temperature of the instant hot water dispenser cannot reach the preset temperature, resulting in low heating efficiency. [Summary of the Invention]

[0003] In view of this, embodiments of the present invention provide a heating control method, device, water dispenser, and storage medium, which can improve the heating efficiency and safety performance of the water dispenser.

The outlet water temperature difference includes the temperature difference between the outlet water temperature and the compensation target temperature.

[0009] If it is determined that the compensation control flow rate is greater than the compensation flow rate threshold or the water temperature difference is greater than or equal to the temperature difference threshold, the water dispenser is controlled to output water according to the compensation control flow rate and the total water flow rate is detected.

[0027] If it is determined that the outlet water temperature difference is less than the temperature difference threshold, continue to execute the step of detecting the total outlet water flow rate.

[0028] Optionally, it also includes:

[0058] Figure 2 This is a cross-sectional structural diagram of a water dispenser provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the water dispenser also includes a heating element 5, an inlet sensor 6, an outlet sensor 7, a flow meter 8, an inlet 9, a control board 10, and a water pump 11.

The control board 10 is located on the outer shell 2 of the dispenser body and is electrically connected to the heating element 5, the outlet sensor 7, the inlet sensor 6, and the flow meter 8.

[0059] In this embodiment of the invention, the heating tube 5 is used to heat the water flowing through it. The heating tube 5 has high thermal conductivity. As an optional solution, the heating tube 5 includes a quartz tube, which converts electrical energy into heat energy. The heat energy is used to transfer heat to the water, and the water in the heating tube 5 is rapidly heated to the target temperature by the strong heat. The inlet water sensor 6 is used to detect the temperature of the inlet water. The outlet water sensor 7 is used to detect the temperature of the outlet water. The flow meter 8 is used to detect the outlet water flow rate and the inlet water flow rate. The inlet water port 9 provides a channel for the water in the water tank 3 to flow into the water path. The water pump 11 is used to provide power for the water in the water path.

[0060] In this embodiment of the invention, the control board 10 is used to detect the inlet water temperature if the outlet water flow rate is greater than the set outlet water flow rate threshold; generate a compensation target temperature based on the inlet water temperature, the acquired initial target temperature, and the set compensation value; generate a compensation control flow rate based on the compensation target temperature and the acquired outlet water temperature using a specified algorithm; determine whether the compensation control flow rate is greater than the set compensation flow rate threshold or whether the calculated outlet water temperature difference is greater than or equal to the set temperature difference threshold, wherein the outlet water temperature difference includes the temperature difference between the outlet water temperature and the compensation target temperature; if it is determined that the compensation control flow rate is greater than the compensation flow rate threshold or the outlet water temperature difference is greater than or equal to the temperature difference threshold, control the water dispenser to dispense water according to the compensation control flow rate and detect the total outlet water flow rate; if the total outlet water flow rate is greater than or equal to the set total flow rate threshold, control the water dispenser to stop heating.

[0061] It should be noted that the implementation method of the control board 10 is not limited in the embodiments of the present invention. For example, it can be a chip.

[0062] In this embodiment of the invention, Figure 2 The various devices of the water dispenser shown are also used to perform... Figure 3 or Figure 4 The heating control method shown will not be described in detail here.

[0063] In the technical solution provided by this invention, if the water flow rate is greater than the set water flow threshold, the inlet water temperature is detected; a compensation target temperature is generated based on the inlet water temperature, the obtained initial target temperature, and the set compensation value; a compensation control flow rate is generated based on the compensation target temperature and the obtained water temperature using a specified algorithm; it is determined whether the compensation control flow rate is greater than the set compensation flow rate threshold or whether the calculated water temperature difference is greater than or equal to the set temperature difference threshold, where the water temperature difference includes the temperature difference between the water temperature and the compensation target temperature; if it is determined that the compensation control flow rate is greater than the compensation flow rate threshold or the water temperature difference is greater than or equal to the temperature difference threshold, the water dispenser is controlled to dispense water according to the compensation control flow rate, and the total water flow rate is detected; if the total water flow rate is greater than or equal to the set total flow rate threshold, the water dispenser is controlled to stop heating, which can improve the heating efficiency and safety performance of the water dispenser.

[0064] Figure 3 A flowchart of a heating control method provided in an embodiment of the present invention is shown below. Figure 3 As shown, the method includes:

[0065] Step 101: If the outflow rate is greater than the set outflow threshold, check the inlet water temperature.

[0066] Step 102: Generate a compensated target temperature based on the inlet water temperature, the obtained initial target temperature, and the set compensation value.

[0067] Step 103: Generate a compensation control flow rate based on the specified algorithm, the target temperature, and the obtained outlet water temperature.

[0068] Step 104: Determine whether the compensation control flow rate is greater than the set compensation flow rate threshold or whether the calculated outlet water temperature difference is greater than or equal to the set temperature difference threshold. The outlet water temperature difference includes the temperature difference between the outlet water temperature and the compensation target temperature.

[0069] Step 105: If it is determined that the compensation control flow rate is greater than the compensation flow rate threshold or the water temperature difference is greater than or equal to the temperature difference threshold, control the water dispenser to dispense water according to the compensation control flow rate and detect the total water flow rate.

[0070] Step 106: If the total water flow rate is greater than or equal to the set total flow rate threshold, control the water dispenser to stop heating.

[0071] In the technical solution provided by this invention, if the water flow rate is greater than the set water flow threshold, the inlet water temperature is detected; a compensation target temperature is generated based on the inlet water temperature, the obtained initial target temperature, and the set compensation value; a compensation control flow rate is generated based on the compensation target temperature and the obtained water temperature using a specified algorithm; it is determined whether the compensation control flow rate is greater than the set compensation flow rate threshold or whether the calculated water temperature difference is greater than or equal to the set temperature difference threshold, where the water temperature difference includes the temperature difference between the water temperature and the compensation target temperature; if it is determined that the compensation control flow rate is greater than the compensation flow rate threshold or the water temperature difference is greater than or equal to the temperature difference threshold, the water dispenser is controlled to dispense water according to the compensation control flow rate, and the total water flow rate is detected; if the total water flow rate is greater than or equal to the set total flow rate threshold, the water dispenser is controlled to stop heating, which can improve the heating efficiency and safety performance of the water dispenser.

[0072] Figure 4 A flowchart of another heating control method provided in an embodiment of the present invention is shown below. Figure 4 As shown, the method includes:

[0073] Step 201: Obtain the inlet water temperature and the initial target temperature.

[0074] In this embodiment of the invention, each step is executed by the control board.

[0075] In this embodiment of the invention, the inlet water temperature can be detected by the inlet water sensor, so that the control board can obtain the inlet water temperature.

[0076] In this embodiment of the invention, the initial target temperature can be set according to the actual situation. As an optional option, the initial target temperature is 80 degrees Celsius (°C).

[0077] Step 202: Generate heating power based on the inlet water temperature and the initial target temperature.

[0078] In this embodiment of the invention, a pre-set correspondence between the inlet water temperature, the initial target temperature, and the heating power is provided, and the corresponding heating power can be generated based on the inlet water temperature and the initial target temperature.

[0079] Step 203: Control the water dispenser to heat water according to the heating power and obtain the water temperature.

[0080] In this embodiment of the invention, the control board controls the heating element of the water dispenser to heat the water flowing through the heating element according to a specified heating power, and detects the outlet water temperature through the outlet water sensor, so that the control board can obtain the outlet water temperature.

[0081] Step 204: Generate the first control flow rate based on the outlet water temperature and the initial target temperature using a specified algorithm.

[0082] As an optional approach, the specified algorithm is the Proportional Integral Differential (PID) algorithm.

[0083] Specifically, the outlet water temperature and the initial target temperature are input into a specified algorithm for calculation, and the first control flow rate is output.

[0084] Step 205: Detect the outflow rate based on the first control flow rate.

[0085] In this embodiment of the invention, the flow meter can detect the outflow velocity and calculate the outflow rate based on the outflow velocity and outflow time.

[0086] Step 206: Determine whether the outflow rate is greater than the flow threshold. If yes, proceed to step 212; otherwise, proceed to step 207.

[0087] In this embodiment of the invention, the traffic threshold can be set by the system based on system performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the traffic threshold.

[0088] In this embodiment of the invention, during the initial water intake phase, when the water dispenser is cold and the water temperature is low, the heat transfer from the heating element to the cold water is relatively slow, resulting in a lag in the temperature sensing of the water outlet sensor and unstable water temperature. After the water flow rate reaches the specified flow rate, the water temperature remains stable. Therefore, a flow rate threshold is set, and the water flow rate is compared with the set flow rate threshold. If it is determined that the water flow rate is greater than the flow rate threshold, it is inferred that the current water flow rate and water temperature are both stable, and step 212 is continued. If it is determined that the water flow rate is less than or equal to the flow rate threshold, it is inferred that the current water flow rate and water temperature are unstable, and step 207 is continued.

[0089] Step 207: Detect the outlet water temperature.

[0090] In this embodiment of the invention, the outlet water temperature is detected by an outlet water sensor, enabling the control board to obtain the outlet water temperature in real time.

[0091] Step 208: Generate a second control flow rate based on the outlet water temperature and the initial target temperature using a specified algorithm.

[0092] As an optional approach, the algorithm is specified as the PID algorithm.

[0093] Specifically, the outlet water temperature and the initial target temperature are input into a specified algorithm for calculation, and the second control flow rate is output.

[0094] In this embodiment of the invention, since the water temperature is unstable in the initial stage of water intake, the water temperature changes in real time, and the water sensor also detects the water temperature in real time.

[0095] Step 209: Determine whether the second control flow rate is less than the set initial flow rate threshold. If yes, proceed to step 210; otherwise, proceed to step 211.

[0096] In this embodiment of the invention, the initial flow rate threshold is set to a flow rate value that ensures no vaporization occurs even when heating at a higher voltage within the flow rate threshold when the water dispenser is cold, thus protecting user safety during the water dispenser heating process. For example, the higher voltage is 1.15 times the rated power.

[0097] In this embodiment of the invention, if it is determined that the second control flow rate is less than the initial flow rate threshold, it indicates that the water dispenser is at risk of vaporization, and step 210 is continued; if it is determined that the second control flow rate is greater than or equal to the initial flow rate threshold, it indicates that the water dispenser is not at risk of vaporization, and step 211 is continued.

[0098] In this embodiment of the invention, if the flow rate is too low, the water will form a jet phenomenon at the outlet, affecting the user's safe use. Therefore, it is necessary to limit and control the flow rate within the flow threshold so that the water flowing through the heating tube will not vaporize.

[0099] Step 210: Control the water dispenser to supply water according to the initial flow rate threshold, and continue to execute step 201.

[0100] In this embodiment of the invention, if there is a risk of vaporization in the water dispenser, the control board controls the flow rate to allow water to enter according to the initial flow rate threshold to ensure user safety, and then continues to execute step 201.

[0101] Step 211: Control the water dispenser to supply water according to the second control flow rate, and continue to execute step 201.

[0102] In this embodiment of the invention, if the water dispenser has no risk of vaporization, the control board controls the flow rate to proceed with water intake according to the current flow rate, i.e., the second control flow rate, and continues to execute step 201.

[0103] Step 212: Detect the inlet water temperature.

[0104] In this embodiment of the invention, the inlet water temperature is detected by an inlet water sensor, enabling the control board to obtain the inlet water temperature in real time.

[0105] In this embodiment of the invention, since the inlet water sensor and the outlet water sensor are in the same water circuit, after the water dispenser has dispensed high-temperature water, the heat of the residual hot water in the heating element will transfer heat to the cold water end after being left to stand for a period of time. Therefore, when the outlet water flow rate is detected to be greater than the flow rate threshold, it is inferred that the current inlet water temperature is the same as the ambient temperature.

[0106] Step 213: Generate a compensated target temperature based on the inlet water temperature, the obtained initial target temperature, and the set compensation value.

[0107] In this embodiment of the invention, if the current inlet water temperature is the same as the ambient temperature, to ensure user experience, the initial target temperature can be compensated based on the inlet water temperature and a compensation value to generate a compensated target temperature. Specifically, a corresponding compensation value is preset based on the inlet water temperature and the initial target temperature; the compensation value is added to the initial target temperature to generate the compensated target temperature. For example, if the inlet water temperature is 5℃, that is, the ambient temperature is also 5℃, and the initial target temperature is 80℃, when the ambient temperature is 5℃, the heat loss when the water flows into the user's cup is relatively large, and the temperature in the cup may only be 70℃. Therefore, a corresponding compensation value of 10℃ is set; the compensation value is added to the initial target temperature to obtain a compensated target temperature of 90℃, so that the temperature in the cup is close to 80℃ to meet the user's needs and ensure user experience.

[0108] Step 214: Generate a compensation control flow rate based on the specified algorithm, the target temperature, and the obtained outlet water temperature.

[0109] As an optional approach, the algorithm is specified as the PID algorithm.

[0110] Specifically, the real-time acquired outlet water temperature and compensation target temperature are input into a specified algorithm for calculation, and the compensation control flow rate is output.

[0111] Step 215: Determine whether the compensation control flow rate is greater than the set compensation flow rate threshold or whether the calculated outlet water temperature difference is greater than or equal to the set temperature difference threshold. If yes, proceed to step 220; otherwise, proceed to step 216.

[0112] In this embodiment of the invention, the outlet water temperature difference includes the temperature difference between the outlet water temperature and the compensation target temperature.

[0113] In this embodiment of the invention, the compensation flow rate threshold is set to a flow rate value that ensures no vaporization occurs even when the water flow rate exceeds the threshold and is heated by a higher voltage, thus protecting user safety during the water dispenser's heating process. For example, the higher voltage is 1.15 times the rated power.

[0114] In this embodiment of the invention, the temperature difference threshold can be set by the system based on performance and / or implementation requirements. This embodiment does not limit the size of the temperature difference threshold. As an optional solution, the temperature difference threshold is 2℃.

[0115] In this embodiment of the invention, if it is determined that the compensation control flow rate is greater than the compensation flow rate threshold or the outlet water temperature difference is greater than or equal to the temperature difference threshold, it indicates that there will be no risk of vaporization during the water dispenser heating process, and step 220 is continued; if it is determined that the compensation control flow rate is less than or equal to the compensation flow rate threshold and the outlet water temperature difference is less than the temperature difference threshold, it indicates that the compensation flow rate threshold is set too high and the outlet water temperature does not reach the compensation target temperature, and step 216 is continued.

[0116] Step 216: Obtain the outlet water temperature according to the preset time interval.

[0117] In this embodiment of the invention, the preset time interval can be set by the system based on performance and / or implementation requirements during specific implementation. This embodiment of the invention does not limit the size of the time interval. As an optional solution, the time interval is 4 seconds.

[0118] Step 217: Determine whether the outlet water temperature difference is less than the temperature difference threshold based on the outlet water temperature. If yes, proceed to step 218; otherwise, proceed to step 219.

[0119] In this embodiment of the invention, the temperature difference threshold can be set by the system based on performance and / or implementation requirements. This embodiment does not limit the size of the temperature difference threshold. As an optional solution, the temperature difference threshold is 2℃.

[0120] In this embodiment of the invention, the outlet water temperature is subtracted from the target temperature to generate an outlet water temperature difference; the outlet water temperature difference is compared with a temperature difference threshold. If it is determined that the outlet water temperature difference is less than the temperature difference threshold, it indicates that the compensation flow rate threshold does not need to be adjusted, and step 218 is continued; if it is determined that the outlet water temperature difference is greater than or equal to the temperature difference threshold, it indicates that the compensation flow rate threshold is set too high and needs further adjustment, and step 219 is continued.

[0121] Step 218: Detect the total outflow rate and continue to step 221.

[0122] In this embodiment of the invention, the outflow velocity is detected by a flow meter, and the total outflow rate is calculated based on the outflow velocity and the total outflow time, and then step 221 is executed.

[0123] Step 219: Generate the adjusted compensation flow rate threshold according to the specified ratio and compensation flow rate threshold, and continue to execute step 216.

[0124] In this embodiment of the invention, the specified ratio can be set by the user according to system performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the specified ratio. As an optional solution, the specified ratio is 5%.

[0125] In this embodiment of the invention, if the compensation flow rate threshold is set too high, the compensation flow rate threshold is lowered according to a specified ratio to generate an adjusted compensation flow rate threshold, and step 216 is continued.

[0126] Step 220: Control the water dispenser's output according to the compensation control flow rate and detect the total water flow.

[0127] In this embodiment of the invention, the outflow velocity is detected by a flow meter, and the total outflow rate is calculated based on the outflow velocity and the total outflow time.

[0128] Step 221: Determine whether the total outflow rate is greater than or equal to the set total flow rate threshold. If yes, proceed to step 222; otherwise, proceed to step 215.

[0129] In this embodiment of the invention, the total traffic threshold can be set by the system based on performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the total traffic threshold.

[0130] In this embodiment of the invention, if the total outflow rate is determined to be greater than or equal to the total flow rate threshold, it indicates that the outflow rate has reached the set flow rate, and step 222 is executed; if the total outflow rate is determined to be less than the total flow rate threshold, it indicates that the outflow rate has not reached the set flow rate, and step 215 is executed.

[0131] Step 222: Control the water dispenser to stop heating.

[0132] In this embodiment of the invention, the control board stops the water dispenser from dispensing water and stops the heating element from heating, thus ending the process.

[0133] In the heating control method provided by this invention, if the water flow rate is greater than the set water flow rate threshold, the inlet water temperature is detected; a compensation target temperature is generated based on the inlet water temperature, the obtained initial target temperature, and the set compensation value; a compensation control flow rate is generated based on the compensation target temperature and the obtained water temperature using a specified algorithm; it is determined whether the compensation control flow rate is greater than the set compensation flow rate threshold or whether the calculated water temperature difference is greater than or equal to the set temperature difference threshold, where the water temperature difference includes the temperature difference between the water temperature and the compensation target temperature; if it is determined that the compensation control flow rate is greater than the compensation flow rate threshold or the water temperature difference is greater than or equal to the temperature difference threshold, the water dispenser is controlled to dispense water according to the compensation control flow rate, and the total water flow rate is detected; if the total water flow rate is greater than or equal to the set total flow rate threshold, the water dispenser is controlled to stop heating, which can improve the heating efficiency and safety performance of the water dispenser.
