[0038] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar components have the same or similar reference numerals throughout the several views. The embodiments described below are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0039] A temperature compensation method of an instant water heater, a computer readable storage medium, an instant water heater and a temperature compensation device of an instant water heater according to embodiments of the present application are described below with reference to the accompanying drawings.

[0040] Figure 1 a flow chart of a temperature compensation method of an instant water heater according to an embodiment of the present application.

[0041] As shown in Figure 1 the temperature compensation method of the instant water heater according to embodiments of the present application can include the following steps:

[0042] S1, obtaining a compensation temperature corresponding to an outlet pipeline of the instant water heater, the compensation temperature including a first compensation temperature and / or a second compensation temperature, wherein the first compensation temperature is used to compensate for a fixed energy loss of the outlet pipeline before the outlet temperature is stabilized, and the second compensation temperature is used to compensate for a steady-state energy loss of the outlet pipeline after the outlet temperature is stabilized.

[0043] S2, compensating a target outlet temperature of the instant water heater according to the compensation temperature.

[0044] S3, controlling the instant water heater to outlet water according to the compensated target outlet temperature.

[0045] Specifically, the instant water heater has a structure of an instant heating pipe and an outlet pipeline as shown in Figure 2When the instant hot water dispenser dispenses water according to the water temperature set by the user, due to the fact that the water outlet pipeline needs to be raised to a certain temperature and the heat loss caused by the water passing through the water outlet pipeline, the actual water outlet temperature of the instant hot water dispenser is different from the temperature set by the user. For example, when the ambient temperature is 25°C, the water dispenser dispenses 80°C hot water, which will heat the original 25°C water outlet pipeline to 80°C. Heating the low-temperature water outlet pipeline to high temperature requires a certain amount of energy, and this energy is one-time, so this part of energy can be referred to as fixed energy loss. When the water outlet of the water dispenser reaches a steady state, for example, when the temperature difference between the inlet temperature of the water outlet pipeline and the outlet temperature of the water outlet nozzle is 1°C, it can be considered that the water outlet has reached a steady state, or when the water outlet reaches a preset value, for example, when the water outlet reaches 200 milliliters, it can be considered that the water outlet has reached a steady state. Due to the heat dissipation effect, the temperature of the hot water outlet from the water outlet nozzle is always lower than the temperature of the water at the inlet of the water outlet pipeline, so this part of the loss can be referred to as the steady-state energy loss of the water outlet pipeline.

[0046] In order to obtain water with the same temperature as the water temperature set by the user (target water outlet temperature), when the user instructs to dispense hot water or warm water, the corresponding compensation temperature of the water outlet pipeline in the instant hot water dispenser can be obtained. The compensation temperature can include a first compensation temperature or a second compensation temperature, or a first compensation temperature and a second compensation temperature, that is, the first compensation temperature is used to compensate for the fixed energy loss of the water outlet pipeline before the water outlet temperature stabilizes, and the second compensation temperature is used to compensate for the steady-state energy loss of the water outlet pipeline after the water outlet temperature stabilizes, and the sum of the first compensation temperature and the second compensation temperature is used to compensate for the fixed energy loss of the water outlet pipeline before the water outlet temperature stabilizes and the steady-state energy loss after the water outlet temperature stabilizes. For example, before the water outlet temperature stabilizes, if the temperature of the water outlet pipeline is greatly different from the target water outlet temperature, the first temperature compensation can be obtained; when the water outlet stabilizes, if the temperature of the water pipeline is less different from the target water outlet temperature, or the water outlet of the instant hot water dispenser reaches a certain value, the second temperature compensation can be obtained; if the temperature of the water pipeline is greatly different from the target water outlet temperature when the water outlet starts, and the user needs a large amount of water, for example, more than a set water amount threshold, such as more than 200 milliliters, the first temperature compensation and the second temperature compensation can be obtained. After the compensation temperature is obtained, the target water outlet temperature of the instant hot water dispenser can be compensated, for example, by adding the temperature to compensate for the target water outlet temperature, and finally the water outlet of the instant hot water dispenser can be controlled according to the compensated target water outlet temperature. In this way, the influence of temperature loss can be eliminated through temperature compensation, the temperature of the water outlet of the water dispenser can be ensured to be the same as the target water outlet temperature, and the user experience can be improved.

[0047] The specific working process of the temperature compensation method of the instant hot water dispenser of the present application is described in detail below.

[0048] According to one embodiment of the present application, the first compensation temperature corresponding to the outlet pipeline in the instant water dispenser is obtained by: obtaining the temperature of the outlet pipeline before water outlet; and determining the first compensation temperature according to the target water outlet temperature, the temperature of the outlet pipeline, a fixed energy loss characteristic parameter, and the specific heat capacity and total mass of residual water in the outlet pipeline.

[0049] Further, according to one embodiment of the present application, the first compensation temperature is determined by:

[0050]

[0051] wherein ΔT a is the first compensation temperature, T 目标 is the target water outlet temperature, T 管温 is the temperature of the outlet pipeline, k1 is the fixed energy loss characteristic parameter, c is the specific heat capacity of the residual water, and m is the total mass of the residual water.

[0052] Specifically, when obtaining the first compensation temperature corresponding to the outlet pipeline in the instant water dispenser, the temperature of the outlet pipeline before water outlet in the instant water dispenser can be obtained first, for example, the temperature of the outlet pipeline before water outlet can be obtained according to a temperature sensor. After obtaining the temperature of the outlet pipeline before water outlet, for example, the first compensation temperature ΔT 目标 is determined according to the target water outlet temperature T 管温 , the temperature of the outlet pipeline T a , a fixed energy loss characteristic parameter k1, and the specific heat capacity c and total mass m of the residual water in the outlet pipeline through the above formula (1). The meaning of ΔT a is that the residual water with a total mass of m needs how much temperature difference to achieve exactly offsetting the energy loss of the outlet pipeline. It should be noted that when calculating through the above formula (1), the fixed energy loss characteristic parameter is a known quantity pre-set in the memory of the instant water dispenser, and the specific heat capacity and total mass of the residual water are known quantities.

[0053] According to one embodiment of the present application, the fixed energy loss characteristic parameter is determined in advance by:

[0054]

[0055] wherein k1 is the fixed energy loss characteristic parameter, c is the specific heat capacity of the residual water, m0 is the water outlet quantity of the instant water dispenser when the water outlet temperature reaches a stable state, T1 is the water outlet temperature of the instant water dispenser when the water outlet temperature reaches a stable state, T2 is the water outlet temperature of the instant water dispenser when the outlet pipeline is removed, and ΔT1 is the temperature difference between the target water outlet temperature of the instant water dispenser and the temperature of the outlet pipeline before water outlet.

[0056] Specifically, when obtaining the characteristic parameters of fixed energy loss, it can be done through experiments. For example, in step 1, when the ambient temperature and the instant hot water dispenser under test are both 25℃, the water temperature of the instant hot water dispenser under test is set to 80℃ (target water temperature), and water is dispensed and dropped into an empty cup. When the water temperature reaches a steady state (that is, the water temperature from the outlet of the instant hot water dispenser is measured by a thermometer and reaches a stable state and no longer changes), the water dispensing is stopped immediately. After completion, the water temperature in the cup is tested and recorded as T1 (the water temperature of the instant hot water dispenser when the water temperature reaches a stable state), and the total mass of the water in the cup is recorded as m, such as 0.2kg. Step 2: Under the same testing environment as above, modify the instant hot water dispenser by completely removing the water outlet pipes. This allows the water from the hot water pipes to pass through the temperature sensor without going through any water path or only through a very short path before falling directly into the cup. Set the outlet water temperature to 80℃ and dispense the same mass of water (m) into the same empty cup. After completion, measure the water temperature in the cup and record it as T2 (the outlet water temperature at the point where the instant hot water dispenser outputs water after removing the water outlet pipes). According to the water heating formula Q = cm0ΔT, where c is the specific heat capacity of water (4200), m0 is the water output of the instant hot water dispenser when the outlet temperature reaches a stable level, and based on the law of conservation of energy, calculate the energy Q required to heat the water from 25℃ to the target temperature of 80℃. 损失 The difference in calories between the two cups of water obtained in steps 1 and 2 can be used to calculate the calories consumed: Q. 损失 =cm0(T2-T1).

[0057] Furthermore, the heating formula for the outlet water pipe is established: Q1 = c 管路 m 管路 ΔT1, where Q1 is the energy required to raise the temperature of the outlet water pipe by ΔT1, and c 管路 For the specific heat capacity of the outlet pipe, m 管路 Let ΔT1 be the total mass of the outlet pipe, and ΔT1 be the temperature difference between the target outlet water temperature of the instant hot water dispenser and the pipe temperature before water dispensing. Since the water circuit, materials, and installation process are consistent for each mass-produced unit, the formula 'c' represents the mass of the outlet pipe. 管路 With m 管路 Both are constants. For ease of calculation, we can define a value k1 such that k1 = c. 管路 *m 管路 Then the formula Q1 = c 管路 m 管路 ΔT1 can be transformed into Q1 = k1ΔT1. According to the law of conservation of energy, Q 损失 The energy required to heat the water outlet pipe from 25℃ to the target temperature of 80℃ is Q1 = Q 损失 Therefore, we can obtain the formula Q. 损失=k1ΔT1. Since the experiment is at ambient temperature and the outlet pipeline is at 25℃ and heated to 80℃, i.e., ΔT1=80-25=55(℃), i.e., through the above experiment and the calculation formula, Q 损失 and ΔT1are known quantities, i.e., the fixed loss characteristic parameter k1can be calculated according to the above formula (1), and the value can be written into the memory of the instant hot water dispenser for temperature compensation calculation when used by the user.

[0058] According to one embodiment of the present application, the second compensation temperature corresponding to the outlet pipeline in the instant hot water dispenser is obtained, comprising: obtaining the ambient temperature and the water flow rate of the outlet pipeline after the outlet temperature is stable; determining the second compensation temperature according to the target outlet temperature, the ambient temperature, the steady-state energy loss characteristic parameter, and the specific heat capacity and water flow rate of the residual water in the outlet pipeline.

[0059] Further, according to one embodiment of the present application, the second compensation temperature is determined by the following method:

[0060]

[0061] wherein, ΔT b is the second compensation temperature, T 目标 is the target outlet temperature, T 环境 is the ambient temperature, k2 is the steady-state energy loss characteristic parameter, c is the specific heat capacity of the residual water, and v is the water flow rate of the residual water.

[0062] Specifically, when obtaining the second compensation temperature corresponding to the outlet pipeline in the instant hot water dispenser, the ambient temperature and the water flow rate of the outlet pipeline after the outlet temperature is stable can be obtained first, for example, the water temperature can be detected by a water inlet temperature sensor, because the water inlet end generally does not exchange heat, i.e., the water inlet temperature is basically equal to the current ambient temperature, and the water flow rate can be obtained by a flow meter or a corresponding speed algorithm, which is not described here. After obtaining the ambient temperature and the water flow rate of the outlet pipeline, the difference between the target outlet temperature and the current ambient temperature is multiplied by the steady-state energy loss characteristic parameter, and the result is divided by the specific heat capacity and the water flow rate of the residual water, to obtain the second compensation temperature. The steady-state energy loss characteristic parameter can be obtained in advance and stored in the memory of the instant hot water dispenser, which can be directly obtained.

[0063] According to one embodiment of the present application, the steady-state energy loss characteristic parameter is determined in advance by the following method:

[0064]

[0065] Where k2 is the steady-state energy loss characteristic parameter, c is the specific heat capacity of the residual water, v is the flow velocity of the residual water, ΔT2 is the temperature difference between the inlet temperature and the outlet temperature of the outlet pipe after the outlet temperature stabilizes, and T 目标 For the target outlet water temperature, T 环境 The ambient temperature.

[0066] Specifically, when obtaining the steady-state energy loss characteristic parameters, the heat dissipation formula, Q, can be used. 散热 =a*(T w -T 环境 )*F, where Q 散热 Where F is the heat dissipation power, a is the area of ​​the outlet pipe, and T is the overall heat transfer coefficient. w The surface temperature of the outlet pipe (approximately the target outlet temperature after the outlet water enters a steady state) can be denoted as T. 目标 ), T 环境 Let Q be the ambient temperature. Since the water circuits, materials, and installation processes are identical for each unit in mass-produced machines, both 'a' and 'F' in the heat dissipation formula are constants. For ease of calculation, they can be treated as a single unit, i.e., k2 = a * F. Therefore, the heat dissipation formula becomes: Q 散热 =k2*(T 目标 -T 环境 According to the law of conservation of energy, the power lost by the water flow is equal to the total power dissipated by the outlet pipe, i.e. Where c is the specific heat capacity of water, m is the mass of water, t is time (seconds), and ΔT a ΔT is the difference between the water temperature detected by the outlet temperature sensor after the water temperature reaches a steady state and the water temperature coming out of the tap. Physically, it represents the temperature loss of the water as it passes through the outlet pipe. For example, the difference between the water temperature coming out of the tap and the inlet temperature of the outlet pipe after the outlet temperature has stabilized can be directly measured using a thermometer; this difference is ΔT. a The value of . Since m is mass and t is time, then In essence, it represents the real-time flow velocity v of the effluent, measured in kg / s. This velocity can be detected using a flow meter. Therefore, the formula... It can be transformed into c*v*ΔT a =k2*(T 目标 -T 环境 Further modifications yield the expression for k2, as shown in formula (4) above. By customizing the experimental environment, for example, a steady-state effluent temperature of 80℃ can be achieved at a temperature of 25℃, i.e., T... 环境 At 25℃, T 目标The temperature difference ΔT2 between the inlet temperature of the outlet pipeline after the outlet water temperature is stable and the outlet water temperature is a known quantity measured, and thus the value of the steady-state energy loss characteristic parameter k2 can be determined by substituting into the formula for calculation, and the value can be written into the memory of the instant hot water dispenser for use by the user to calculate the temperature compensation.

[0067] According to one embodiment of the present application, the target outlet water temperature of the instant hot water dispenser is compensated according to the compensation temperature, which includes: superimposing a first compensation temperature on the target outlet water temperature to obtain a target compensation temperature before the outlet water temperature is stable; and / or superimposing a second compensation temperature on the target outlet water temperature to obtain a target compensation temperature after the outlet water temperature is stable.

[0068] Specifically, when the target outlet water temperature of the instant hot water dispenser is compensated according to the compensation temperature, for example, when the current outlet water volume of the instant hot water dispenser is lower than a set threshold, such as when the current outlet water volume does not reach 100 ml, or when the current outlet water temperature does not reach a steady state, the first compensation temperature can be added to the target outlet water temperature to obtain the target compensation temperature before the outlet water temperature stabilizes. For example, the user sets the outlet water temperature of the instant hot water dispenser to 70°C (target outlet water temperature), and the first compensation temperature obtained through calculation is 3°C, so the target outlet water temperature can be adjusted, and the target outlet water temperature and the first compensation temperature are added to obtain the target compensation temperature before the outlet water stabilizes (70°C+3°C), and the instant hot water dispenser performs outlet water at 73°C, which can just offset the fixed loss of energy, so that the outlet water temperature of the instant hot water dispenser is the target outlet water temperature. Or when the current outlet water temperature reaches a steady state, for example, the user sets the outlet water temperature of the instant hot water dispenser to 70°C (target outlet water temperature), that is, the water temperature of the outlet nozzle is 70°C, and after entering the steady state, the second compensation temperature obtained through calculation is 1°C, that is, the water temperature of the outlet nozzle will decrease by 1°C after passing through the outlet pipeline, so the temperature value needs to be added to the target outlet water temperature to increase the outlet water temperature to obtain the target compensation temperature after the outlet water stabilizes (70°C+1°C). In this way, the water temperature after passing through the outlet pipeline will also be lost by 1°C, so as to realize the purpose of the outlet water temperature of the instant hot water dispenser being 70°C. For example, the user sets the outlet water temperature of the instant hot water dispenser to 70°C (target outlet water temperature), and the first compensation temperature obtained through calculation is 3°C, so the target outlet water temperature can be adjusted, and the target outlet water temperature and the first compensation temperature are added to obtain the target compensation temperature before the outlet water stabilizes (70°C+3°C), and the instant hot water dispenser performs outlet water at 73°C, which can just offset the fixed loss of energy, so that the water in the cup is the target outlet water temperature. If the instant hot water dispenser continues to perform outlet water at this time, that is, after the outlet water stabilizes, a second temperature compensation value is obtained, for example, the second temperature compensation value obtained through calculation is 1°C, and the target compensation temperature obtained before the outlet water stabilizes and the second temperature compensation value are continuously added (73°C+1°C) to obtain the target compensation temperature after the outlet water stabilizes (74°C). Thus, the outlet water is performed at a temperature of 74°C, and after two losses, the outlet water temperature of the instant hot water dispenser is 70°C, which is the same as the target outlet water temperature.

[0069] The temperature compensation method of the instant hot water dispenser of the present application will be described below. Figure 3
