The preheating time is crucial to the preheating effect. If the preheating time is too long, the water in the heating device may reach the boiling point, thereby generating a large number of bubbles. If the preheating time is too short, the water temperature may be too low and insufficient to achieve the preset preheating effect. Therefore, how to accurately control the preheating time has become an urgent problem to be solved. Summary of the invention

[0019] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0020] There are many heating devices on the market, such as conventional water dispensers, instant hot water dispensers or instant hot water heaters. Users can set the water outlet temperature (i.e. set the water outlet temperature) according to specific needs. When the user uses the heating device, the heating device will heat the water in the device based on the preset heating scheme and the set water outlet temperature, so that the temperature of the water in the device reaches the set water outlet temperature, and then the heating device can output the water after the temperature is increased, thereby meeting the needs of the user. For example, the instant hot water dispenser includes a water storage tank, a water pump, an instant hot pipe and a water outlet. When the user presses the water outlet button of the instant hot water dispenser, the water pump can pump the water in the water storage tank into the instant hot pipe. When the water flows in the instant hot pipe, the instant hot pipe heats the water according to the power corresponding to the set water outlet temperature. When the water flows from the instant hot pipe to the water outlet, the instant hot pipe completes the heating of the water. The heated water can be output to the outside of the heating device through the water outlet and received by the user.

[0021] If there is no hot water stored in the heating device, the temperature of the water that comes out at the beginning after the user presses the water outlet button may be low. In particular, some instant heating devices, such as instant hot water dispensers or instant hot water heaters, can achieve the effect of heating at any time. There is no need to perform long-term heating and heat preservation and other hot water storage work inside the instant heating device, so that the instant heating device generally does not have water storage hot filling and related heating detection components. This can bring certain benefits. For example, this will allow the instant heating device to save more energy, reduce the corresponding component costs, and make the volume of the instant heating device smaller than that of non-instant heating devices, and have higher spatial adaptability. However, not storing hot water will bring certain disadvantages. It takes time for the instant heating device to heat the water. If it is not preheated, the water temperature that just comes out after the user presses the water outlet button may be low, and the water temperature that falls into the user's cup may also be low, which may cause problems such as the instant noodles not being able to be soaked because the hot water is not hot enough, thereby reducing the user's experience.

[0022] Therefore, some heating equipment now has a preheating function. After the user presses the hot water function, the heating equipment heats the water first, and the water pump does not work, that is, no water is discharged at this time. After the water in the heating equipment is heated to a certain temperature, the water pump starts working and discharges water for the user. This ensures that the temperature of the water is high even at the beginning, which is beneficial to improving the user experience.

[0023] Preheating time is crucial to the preheating effect. If preheating is too long, the temperature of the water in the heating tube may reach the boiling point, forming a large number of boiling bubbles, and the water vapor will be mixed together and sprayed into the user's cup, which may even cause burns to the user due to the spray splash. If the preheating time is too short, the water temperature may be too low, which is not enough to achieve the preset preheating effect. Especially for some instant hot water dispensers, the volume of water in the heating tube in the instant hot water dispenser is generally very small, at the level of more than ten milliliters. If it is preheated at a power of 2000 watts, it only takes about 4 seconds to preheat 15 milliliters of water in the heating tube from 30 degrees to 90 degrees. The heating speed is very fast. If you are not careful, the water may reach the boiling point. However, if the preheating is ended early, the water temperature may be too low. Therefore, for instant hot water dispensers, the ability to control the preheating time is particularly important.

[0024] To solve the above problems, please refer to Figure 1 and Figure 2 The embodiment of the present application provides a preheating control method applied to a heating device 100, the preheating control method comprising:

[0025] Step 011: Calculate the heat accumulation value once every preset time, and the heat accumulation value is determined according to the actual heating power within the preset time and the preset time;

[0026] Specifically, the heating device 100 also includes a processor 20 and a heating device 30, wherein the heating device 30 is used to preheat and heat water, and the processor 20 is used to control the heating device 30 to work and stop working. The heating device 30 preheats water with a certain heating power. At this time, the processor 20 can determine the heat accumulation value according to the actual heating power and the preset time within the preset time every preset time, so as to determine how much heat is generated within the preset time, so as to facilitate the confirmation of the total heat accumulation value accumulated by the heating device 30 at the current moment. Among them, the preset time is usually small, for example, 10 milliseconds, then the processor 20 will calculate the heat accumulation value every 10 milliseconds to avoid the calculation interval between the two times being too long, which makes it difficult for the processor 20 to find in time that the preheating effect reaches the preset preheating effect, and control the heating device 30 to stop preheating, thereby causing the water temperature to be too high.

[0027] Furthermore, the formula Q=P*t can be used to calculate heat, where Q is heat, P is power, and t is heating time. In the above formula, Q is the heat energy obtained after all mechanical energy is converted into heat energy under ideal conditions. However, in actual use, the mechanical energy generated by the heating device 100 cannot be completely converted into heat energy, and the mechanical energy and heat energy need to be converted through the thermal efficiency of the heating device 30. Therefore, the formula Q=P*t can be further converted into Q 实际 =P1*t s *η, where Q 实际 is the cumulative value of the heat actually generated within the preset time, in joules; P1 is the preset power within the preset time, in watts; η is the thermal efficiency of the heating device 30, and η is a constant with a value less than or equal to 1; t s Refers to the preset duration in seconds. For example, if the heat accumulation value is counted every 10 milliseconds, then t s =0.01. In addition, there are no excessive restrictions on the value of the preset power, as long as it is within the rated heating power of the heating device 30. For example, if the rated heating power of the heating device 30 is 2000 watts, then the preset power can be any value between 0-2000 watts.

[0028] Because the grid voltage is constantly fluctuating and the voltage will have a certain impact on the heating power, the heating device 30, such as a heat pipe, generally has a constant resistance value under different working conditions. 2 / R, U is the voltage, R is the resistance. According to the formula, when the resistance is constant, the power is proportional to the square of the voltage. Therefore, the actual heating power of the heating device 30 is constantly changing based on the preset power. The heating power of the heating device 30 is generally calculated based on the rated heating power. The rated heating power refers to the working power of the heating device 30 when the voltage is at the rated voltage, where the rated voltage is generally 220 volts. Therefore, the preset power is multiplied by and 220 2 The value obtained by weighting the ratio of is the actual heating power, where U 实际 is the actual voltage within the preset time, that is, the actual heating power can be determined according to the preset power within the preset time, the actual voltage within the preset time, and the rated voltage. Then, the processor 20 can also determine the actual voltage within the preset time according to the formula Q 实际 =P1*U 2 / 220 2 *t s *η, to calculate the cumulative heat value within the preset time.

[0029] Step 012: Calculate the total calorie accumulation value at the current moment, which is the sum of all calorie accumulation values ​​from the start of preheating to the current moment;

[0030] Specifically, after obtaining the calculated heat value at the current moment, the processor 20 needs to calculate the sum of all heat accumulation values ​​from the start of preheating to the current moment, that is, the total heat accumulation value, so as to determine the current preheating effect according to the total heat accumulation value. For example, at this time, the formula or formula To calculate the total heat accumulation value, Σ is a summation operator, and t represents the current moment. Of course, since the voltage usually changes in actual use, the processor 20 will use the following formula to perform calculations to obtain a more accurate total heat accumulation value, so as to accurately determine whether the preheating effect reaches the preset heating effect.

[0031] Step 013: When the total heat accumulation value is greater than or equal to the target heat, it is determined that the preheating is ended. The target heat is determined based on the set water outlet temperature and the actual water temperature when the preheating starts.

[0032] Specifically, in addition to calculating the total calorie accumulation value, the processor 20 also needs to determine the target calorie to determine whether to stop controlling the preheating according to the relationship between the target calorie and the total calorie accumulation value.

[0033] According to the formula Q 目标 =cm1ΔT 目标 The heat can be calculated, where Q 目标 is the target heat; c is the specific heat capacity of water, which is 4200; m1 is the total weight of water in the heating device 30. Since the heating device 30 has a fixed structure, the total weight of water that can be stored is fixed, so this value is known. For example, for some instant hot water dispensers, the water in the instant hot pipe generally fills the instant hot pipe, so m1 is a constant, such as 0.015 kg, and this value can be preset in the processor 20 of the heating device 100; ΔT 目标 is the target change value of the water temperature during the preheating process. Therefore, the processor 20 can determine the target heat by only obtaining the target change value of the water temperature during the preheating process.

[0034] The water outlet 31 of the heating device 30 may be provided with a temperature measuring device 40, which is used to collect the actual water temperature. Each user can set the water outlet temperature according to their own needs. When the user presses the water outlet button and the heating device 100 starts preheating, the processor 20 can obtain the current actual water temperature through the temperature measuring device 40, that is, the actual water temperature at the beginning of preheating, and then subtract the actual water temperature at the beginning of preheating from the set water outlet temperature to obtain the change value of the water temperature from the beginning of preheating to the actual water outlet. The processor 20 will also set a corresponding preset coefficient for the target change value of the water temperature during the preheating process. After multiplying the change value of the water temperature during the process from the beginning of preheating to the actual water outlet by the preset coefficient, the target change value of the water temperature during the preheating process can be obtained. In this way, the processor 20 can determine the amount of heat (i.e., target heat) and the temperature (i.e., target preheating water temperature) that the water in the heating device 30 needs to accumulate at the end of preheating based on the target change value of the water temperature during the preheating process. Among them, the value range of the preset coefficient is [0, 1].

[0035] For example, the user sets the water outlet temperature to 90 degrees, that is, the preset water outlet temperature is 90 degrees, the actual water temperature at the beginning of preheating is 30 degrees, and the preset coefficient is 0.9. Then the target water temperature change value during the preheating process is calculated according to the formula ΔT 目标 = k*ΔT1 = 0.9*(90-30) = 54 (degrees), where k is a preset coefficient. Therefore, the goal of this preheating is to increase the water temperature of 30 degrees by 54 degrees, so that the water temperature in the heating device 30 reaches 84 degrees, that is, the target preheating water temperature is 84 degrees.

[0036] Then, after the processor 20 determines the target heat according to the set water outlet temperature and the actual water temperature at the start of preheating, it can compare the total heat accumulation value and the target heat. When the total heat accumulation value is greater than or equal to the target heat, it is determined that the preheating effect at this time reaches the target preheating effect, and the processor 20 can determine that the preheating is over. At the same time, since the preset time length is generally short, for example, 10 milliseconds, that is, the processor 20 will determine the total heat accumulation value once every 10 milliseconds, then even if the total heat accumulation value is greater than the target heat, the difference between the two will not be too large, and will not cause the water temperature to be too high or even reach the boiling point. In the case where the total heat accumulation value is less than the target heat, the processor 20 can confirm that the preheating effect at this time has not reached the preset preheating effect, and it is necessary to continue preheating. After the heating device 30 is preheated for the preset time again, the processor 20 will re-enter the step of calculating the heat accumulation value, so as to timely find the moment when the preheating effect has reached the preset preheating effect, and timely control the heating device 30 to stop preheating.

[0037] The preheating control method of the embodiment of the present application first determines the target heat that needs to be reached at the end of preheating according to the set water outlet temperature and the actual water temperature at the beginning of preheating. Then, at every preset time, according to the actual power and the preset time within the preset time, the heat accumulation value is calculated once to calculate the heat accumulation value at the current moment, so as to facilitate the real-time judgment of the current preheating effect according to the heat accumulation value at the current moment. When the total heat accumulation value is greater than or equal to the target heat, it means that the preheating effect at this time has reached the preset preheating effect, and the preheating end can be determined. In this way, the heating device 100 can accurately determine the time when the preheating effect reaches the preset preheating effect by calculating the total heat accumulation value at the current moment at every preset time, and comparing the total heat accumulation value with the target heat, so as to accurately control the preheating time and ensure the rationality of the preheating time, so that the preheating effect can reach the target preheating effect, improve the user experience, and the heating device 100 can also prevent the actual water temperature after preheating from being too high, avoid the use risks such as splashing caused by boiling water, thereby ensuring the personal safety of the user.

[0038] See also Figure 2 In some embodiments, the preset power is determined based on the duration of the preheating.

[0039] Specifically, during the preheating process, the processor 20 can also design some algorithms to make the preset power change in real time according to the preset rules. For example, as time goes by, the preset power gradually increases to gradually increase the preheating rate of the heating device 100; for another example, as time goes by, the preset power gradually decreases to avoid the water temperature rising too fast in the late stage of preheating, resulting in too high water temperature after preheating. Therefore, when preheating starts, the processor 20 can count the duration of preheating, and use the power corresponding to the current preheating duration in the preset rules as the preset power, so that the preset power can meet the heating effect requirements corresponding to different times.

[0040] See also Figure 2 and Figure 3 In some embodiments, the preset control method further includes:

[0041] Step 014: When preheating is completed, control the heating device 100 to heat and discharge water.

[0042] Specifically, when preheating is completed, the temperature of the water in the heating device 30 still does not reach the set water outlet temperature. At this time, the processor 20 will continue to control the heating device 30 to heat, and control the heating equipment 100 to start discharging water when the preheating is completed. After preheating, the water with a certain temperature can reach the set water outlet temperature after flowing through the heating device 30, so that the water temperature of the water output by the heating equipment 100 can meet the user's needs, thereby improving the user experience.

[0043] See also Figure 2 and Figure 4 In some embodiments, step 013: when the total calorie accumulation value is greater than or equal to the target calorie, determining that the preheating is over includes:

[0044] Step 0131: When the total heat accumulation value is greater than or equal to the target heat and the actual water temperature in the heating device 30 matches the target preheating water temperature, the preheating is determined to be completed. The target preheating water temperature is determined based on the actual water temperature in the heating device 30 at the start of preheating and the set water outlet temperature.

[0045] Specifically, the temperature measuring device 40 can collect the actual water temperature, so that the processor 20 can also obtain the target preheating water temperature when determining the target heat, wherein the target preheating water temperature can be determined based on the actual water temperature in the heating device 30 at the start of preheating and the set water outlet temperature. The specific determination method can refer to the step of obtaining the target preheating water temperature in the above-mentioned method for determining the target heat. For the sake of brevity, it will not be repeated here.

[0046] Therefore, the processor 20 can determine the preheating effect according to the actual water temperature while determining the preheating effect according to the total heat accumulation value. When the processor 20 determines that the total heat accumulation value is greater than or equal to the target heat, the processor 20 will also obtain the actual water temperature in the heating device 30 at this time through the temperature measuring device 40 to confirm whether the actual water temperature in the heating device 30 matches the target preheating water temperature. If the actual water temperature in the heating device 30 does not match the target preheating water temperature at this time, for example, the difference between the actual water temperature in the heating device 30 and the target preheating water temperature is large, it means that during the preheating process, a large amount of heat generated by the heating device 30 is lost to other devices of the heating device 100. At this time, the processor 20 controls the heating device 30 to continue preheating. After the heating device 30 is preheated again for a preset time, the processor 20 will re-enter the step of calculating the heat accumulation value. If the actual water temperature in the heating device 30 matches the target preheating water temperature, that is, the total heat accumulation value and the actual water temperature both determine that the preheating effect at this time reaches the preset preheating effect, the processor 20 can determine that the preheating is over, thereby determining the time when the preheating ends from multiple angles, so that the processor 20 can control the preheating time more accurately, thereby ensuring the preheating effect of the heating equipment 100.

[0047] Furthermore, the processor 20 can control the temperature measuring device 40 to work all the time during the preheating process to monitor the water temperature in real time, so that the processor 20 can better control the preheating time. Alternatively, the processor 20 can control the temperature measuring device 40 to work only when the total heat accumulation value is greater than or equal to the target heat, so as to further confirm whether the actual water temperature in the heating device 30 matches the target preheating water temperature by using the temperature measuring device 40, while reducing the energy consumption of the temperature measuring device 40.

[0048] See also Figure 2 and Figure 5 In order to better implement the above-mentioned preheating control method, the embodiment of the present application also provides a preheating control device 10 applied to a heating device 100.

[0049] The preheating control device 10 further includes a control module 14. The control module 14 is used to control the heating device 100 to heat and discharge water when the preheating is finished.

[0050] The determination module 13 is specifically used to determine that preheating is over when the total heat accumulation value is greater than or equal to the target heat and the actual water temperature in the heating device 30 matches the target preheating water temperature. The target preheating water temperature is determined based on the actual water temperature in the heating device 30 at the start of preheating and the set water outlet temperature.
