The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

Fig. 1 is a flowchart of a preheating method of an instant water dispenser according to an embodiment of the present invention.
As shown in fig. 1, the preheating method of the instant water dispenser according to the embodiment of the invention may include the following steps:
S1, obtaining a target temperature rise value and target preheating time for preheating residual water in the heat pipe to a target temperature.
S2, preheating the residual water in a power reduction mode in the target preheating time until the temperature rise value of the residual water reaches the target temperature rise value.
Specifically, when a user needs to use the instant heating water dispenser to drink water, after the hot water outlet function is pressed, the heat pipe firstly preheats the residual water in the pipe so as to ensure that the temperature of the water just coming from the water outlet is higher, when preheating is performed, a target temperature rise value for preheating the residual water in the instant heat pipe to the target temperature can be obtained, for example, the set water outlet temperature of the user, namely, the target temperature can be obtained firstly, and the residual water temperature in the instant heat pipe can be obtained through the temperature sensor, so that the target temperature rise value can be obtained according to the temperature difference between the two, and the target preheating time for preheating the residual water in the instant heat pipe to the target temperature can be obtained, for example, the time spent for increasing the residual water temperature to the target temperature, namely, the target preheating time can be obtained through a table lookup mode and the like, wherein in the relation table, the target preheating time and the target temperature rise value are in one-to-one correspondence, and the corresponding target preheating time can be determined after the target temperature rise value is determined. And at the target preheating time, the residual water can be preheated in a power reduction mode, namely, after the residual water is preheated for a period of time with higher power, the residual heat is preheated with lower power until the temperature rise value of the residual water reaches the target temperature rise value, the current temperature of the residual water can be determined to reach the target temperature, and the preheating is finished at the moment, namely, the hot water dispenser can normally discharge water. Therefore, the high preheating temperature can be realized, the problem of splashing caused by boiling of the discharged water can be avoided, and the use risk is avoided while the user experience is improved.
The specific working procedure of the preheating method of the instant water dispenser of the present invention is described in detail as follows.
According to one embodiment of the present invention, obtaining a target temperature rise value for preheating residual water, i.e., in a heat pipe, to a target temperature includes: acquiring a first temperature difference between a target temperature and the temperature of residual water in the heat pipe; and determining a target temperature rise value according to the first temperature difference value and the first preset coefficient. The first preset coefficient may be determined according to practical situations.
Specifically, when the target temperature rise value for preheating the residual water in the heat pipe to the target temperature is obtained, the target temperature and the residual water temperature in the heat pipe may be obtained first, for example, the target temperature may be selected directly by the user through the control panel of the instant heating water dispenser, for example, the user wants to drink warm water, the temperature may be selected directly to be 60 ℃, and the like, i.e., the target temperature may be obtained directly in the memory in the instant heating water dispenser. Namely, the residual water temperature in the heat pipe can be obtained by arranging a temperature sensor at the water outlet position. After the target temperature and the residual water temperature in the heat pipe are obtained, the difference between the target temperature and the residual water temperature in the heat pipe, namely the first temperature difference, is calculated. When the first temperature difference is obtained, the target temperature rise value can be determined according to the first temperature difference and a first preset coefficient. For example, when the target temperature set by the user is 90 ℃, i.e. the residual water temperature in the heat pipe is 30 ℃, the first temperature difference is 60 ℃, the value range of the first preset coefficient may be set in the range of 0 to 1, for example, the first preset coefficient may be set to 0.9, so that the target temperature rise value may be determined to be 54 ℃ (0.9×60 ℃), i.e. the target of the preheating is to increase Yu Shuiwen ℃ in the pipe at 30 ℃ by 54 ℃ to 84 ℃. Through multiplying first temperature difference and first default coefficient, can make the temperature rise value reduce some, prevent that the temperature is too high, have the condition such as scald user when going out water, play the effect of protection.
According to one embodiment of the present invention, obtaining a target warm-up time for warming up residual water, i.e., in a heat pipe, to a target temperature includes: determining initial target preheating time according to the target temperature rise value, namely the maximum preheating power of the hot water dispenser, the specific heat capacity of residual water and the total mass; and determining the target preheating time according to the initial target preheating time and a second preset coefficient, wherein the second preset coefficient is larger than 1.
Specifically, when the target preheating time for preheating the residual water in the heat pipe to the target temperature is obtained, the initial target preheating time can be determined according to the target temperature rise value, namely the maximum preheating power of the hot water dispenser, the specific heat capacity and the total mass of the residual water, for example, the initial target preheating time can be calculated according to the formula t=cm Δt/P, wherein T is the initial target preheating time, c is the specific heat capacity of the residual water, m is the total mass of the residual water, and the initial target preheating time can be calculated because the heat pipe structure is fixed, namely the value is constant, and is preset in a memory (for example, 0.015 kg), Δt is the target temperature rise value, and P is the maximum preheating power of the hot water dispenser, for example, 2000W. After the initial target preheating time is determined, the target preheating time is determined according to the initial target preheating time and a second preset coefficient, for example, the second preset coefficient can be set to be 2, the initial target preheating time is multiplied by the second preset coefficient, the target preheating time is determined, and the initial target preheating time is multiplied by the second preset coefficient, so that the preheating time can be prolonged, the preheating can be conveniently carried out with lower power, the heating speed of residual water in a pipe is slower, the requirement of the reaction speed of a system is favorably reduced, and the possibility of boiling splashing of effluent is reduced.
According to one embodiment of the present invention, the target temperature rise value includes a residual water target temperature rise value and a heat pipe target temperature rise value, and acquiring the target temperature rise value for preheating residual water in the heat pipe to the target temperature includes: acquiring a first temperature difference between the target temperature and the residual water temperature in the heat pipe, and determining a residual water target temperature rise value according to the first temperature difference and a first preset coefficient; and obtaining a second temperature difference value between the target temperature and the tube temperature of the heat tube, and determining a target temperature rise value of the heat tube according to the second temperature difference value and a third preset coefficient. The third preset coefficient may be determined according to practical situations.
Specifically, the water within the heat pipe is heated to a target temperature, taking into account the heat transfer problem of the heat pipe body. Such as: the energy required for heating the residual water in the heat pipe with the pipe body of 25 degrees is not only the energy for heating the water to 60 degrees, but also the energy for heating the heat pipe body to 60 degrees, and the two parts of energy are added together to be the total preheating energy. I.e. the temperature rise value of the temperature of the heat pipe itself needs to be considered. The target temperature rise value may include a target temperature rise value of the residual water and a target temperature rise value of the heat pipe, and when the target temperature rise value of preheating the residual water in the heat pipe to the target temperature is obtained, the target temperature and the residual water temperature in the heat pipe may be obtained first, for example, the target temperature may be selected directly by a user through a control panel of the instant water dispenser, or the temperature may be selected by the user through an intelligent device networked with the instant water dispenser. Namely, the residual water temperature in the heat pipe can obtain the corresponding residual water temperature through a temperature sensor arranged at the water outlet position. After the target temperature and the residual water temperature in the heat pipe are obtained, the difference between the target temperature and the residual water temperature in the heat pipe, namely the first temperature difference, is calculated. When the first temperature difference is obtained, the residual water target temperature rise value can be determined according to the first temperature difference and a first preset coefficient. For example, when the target temperature set by the user is 90 ℃, that is, the residual water temperature in the heat pipe is 30 ℃, the first temperature difference is 60 ℃, the value range of the first preset coefficient can be set in the interval of 0 to 1, for example, the first preset coefficient can be set to 0.9, so that the target temperature rise value can be determined to be 54 ℃ (0.9×60 ℃), that is, the target of preheating is to raise Yu Shuiwen ℃ in the pipe at 30 ℃ by 54 ℃ to 84 ℃, and the temperature rise value can be reduced by multiplying the first temperature difference by the first preset coefficient, so that the conditions of excessive temperature, scalding the user when water is discharged are prevented, and the like, thereby playing a role of protection.
The target temperature and the tube temperature of the heat pipe are obtained, for example, the tube temperature of the heat pipe may be obtained from a temperature sensor. After the target temperature and the tube temperature of the heat tube are obtained, the difference between the two temperatures, namely, a second temperature difference is calculated. And when the second temperature difference is obtained, determining the target temperature rise value of the heat pipe according to the second temperature difference and a third preset coefficient. For example, when the target temperature set by the user is 90 ℃, that is, the tube temperature of the heat tube is 30 ℃, the second temperature difference is 60 ℃, and the value range of the second preset coefficient may be set in the range of 0 to 1, for example, the second preset coefficient may be set to 0.8, so that it may be determined that the target temperature rise value of the heat tube is 48 ℃ (0.8×60 ℃), that is, the target of the preheating is to raise the temperature of the residual water in the tube at 30 ℃ by 48 ℃ to 78 ℃.
According to one embodiment of the present invention, obtaining a target warm-up time for warming up residual water, i.e., in a heat pipe, to a target temperature includes: determining the residual water target preheating time according to the residual water target temperature rise value, namely the maximum preheating power of the hot water dispenser, and the specific heat capacity and the total mass of residual water; determining the target preheating time of the instant heat pipe according to the target temperature rise value of the instant heat pipe, the maximum preheating power of the instant heating water dispenser and the specific heat capacity and the total mass of the instant heat pipe; determining initial target preheating time according to the residual water target preheating time and the heat pipe target preheating time; and determining the target preheating time according to the initial target preheating time and a second preset coefficient, wherein the second preset coefficient is larger than 1.
Specifically, when the target preheating time for preheating the residual water in the instant heat pipe to the target temperature is obtained, the residual water target preheating time can be determined according to the residual water target temperature rise value, the maximum preheating power of the instant heating water dispenser, the specific heat capacity and the total mass of the residual water, for example, the residual water target preheating time can be calculated according to the formula t=cm Δt/P, where T is the residual water target preheating time, c is the specific heat capacity of the residual water, and m is the total mass of the residual water, and the instant heat pipe structure is fixed, i.e., the value is constant, preset in a memory (e.g., 0.015 kg), Δt is the residual water target temperature rise value, and P is the maximum preheating power of the instant heating water dispenser, for example, 2000W, thereby calculating the residual water target preheating time.
The target preheating time of the instant heat pipe can be determined according to the target temperature rise value of the instant heat pipe, the maximum preheating power of the instant heat water dispenser and the specific heat capacity and total mass of the instant heat pipe, for example, the instant heat pipe can be regarded as an ideal uniform material, and the mass of each instant heat pipe and the specific heat capacity of the instant heat pipe are constant because the mass and the material of the instant heat pipe are consistent, and the constant b can be defined as the product of the mass of the instant heat pipe and the specific heat capacity of the instant heat pipe. The value of the constant b can be calculated in advance by experiments, for example, according to the formula t=b Δt/P, after the laboratory heats the heat pipe body, i.e. at 2000W power for 1 second, the actual measurement is raised by 30 degrees, i.e.: 1=b×30/2000, whereby the value of the constant b can be calculated as 66.7, and this value is stored in the memory to be used as a constant. Thus, the target preheating time of the instant heating pipe can be calculated according to the formula t=b delta T/P, wherein T is the target preheating time of the instant heating pipe, b is a pre-stored constant, delta T is the target temperature rise value of the instant heating pipe, and P is the maximum preheating power of the instant heating water dispenser.
After the remaining water target preheating time and the heat pipe target preheating time are determined, the initial target preheating time, i.e., the sum of the remaining water target preheating time and the heat pipe target preheating time, can be determined as the initial target preheating time according to the remaining water target preheating time and the heat pipe target preheating time. After the initial target warm-up time is obtained, the target warm-up time may be determined according to the initial target warm-up time and the second preset coefficient. For example, the second preset coefficient may be 2, and the initial target preheating time is multiplied by the second preset coefficient to be used as the target preheating time, so that the preheating time can be prolonged, and the preheating can be performed with lower power, so that the heating speed of the residual water in the pipe is slower, the requirement of the reaction speed of the system is reduced, and the possibility of boiling splashing of the outlet water is reduced.
According to one embodiment of the present invention, the preheating method of the instant heating water dispenser further comprises: determining target temperature rise energy according to the target temperature rise value; and determining the target preheating power of the instant heating water dispenser according to the relation among the target temperature rise energy, the target preheating time and the preheating power and the preheating time of the instant heating water dispenser.
Specifically, after the target temperature rise value is obtained, the target temperature rise energy may be determined according to the target temperature rise value, for example, the target temperature rise energy may be determined by the formula q=cm Δt, and the target temperature rise energy may include two parts: i.e., the energy required for preheating the residual water in the heat pipe to the target temperature and the energy required for preheating the heat pipe to the target temperature, the sum of the two energy can be used as the target temperature rise energy. For example, the target temperature rise energy of the residual water is determined according to the specific heat capacity and the total mass of the residual water and the target temperature rise value of the residual water, the target temperature rise energy of the heat pipe is determined according to the specific heat capacity and the mass of the heat pipe and the target temperature rise value of the heat pipe, and the two energies are added to be used as the target temperature rise energy. After the target temperature rising energy is obtained, the target preheating power of the instant heating water dispenser can be determined according to the relation between the target temperature rising energy, the target preheating time and the preheating power and the preheating time of the instant heating water dispenser, for example, the target preheating time can be divided into two parts, the target preheating power of the instant heating water dispenser can be determined to be preheated at the maximum preheating power of the instant heating water dispenser in the first part, namely in the beginning stage of the preheating time, and the target preheating power of the instant heating water dispenser can be determined to be preheated at the smaller preheating power according to the residual temperature rising energy in the second part, namely after the preheating time. Therefore, the preheating is performed by first high power and then low power, so that the purposes of high preheating temperature and splashing prevention can be simultaneously realized.
According to one embodiment of the present invention, the target preheating power is expressed by the following formula:
wherein Q is Target object For the target temperature rise energy, t Target object For target preheating time, M1 and M2 are target preheating power, M1 > M2, t is current time, and ta is a first time node. Wherein M1 is the maximum preheating power of the instant heating water dispenser, M2 is determined according to the initial target preheating time, the target preheating time and the target temperature rise energy, and ta is determined according to the initial target preheating time.
Specifically, after the target warm-up time is acquired, a change function of the actual output power and the time t in the target warm-up time can be obtained: p (P) Currently, the method is that ＝f(t)(0≤t≤t Target object ) The function is the function of the current required output power changing along with time, namely, after the function is obtained, the function can be changed from 0 moment (starting preheating) to t Target object The time period calculates how much power should be output at each time and outputs it into the instant heat pipe. When the function is obtained, from q=pt, it is known that between 0 and t Target object The total energy actually output during the time instant, i.e. the heat pipe preheating, is actually the fixed integral of the power output over time:the target temperature rise energy is taken as the total energy actually output, and the method can obtain In obtaining the target preheating power, for example, the heating may be performed at the maximum preheating power of the instant heating water dispenser through experiments, the heating time may be determined according to the initial target preheating time, for example, half of the initial target preheating time is heated at the maximum preheating power of the instant heating water dispenser, and the remaining time is heated at the power M2. In calculating the power M2, the energy generated by heating with the maximum heating power may be calculated first. With reference to FIG. 2, integration->The geometric meaning of (2) is that the total area S of the power between 0 and ttarget, i.e. the target temperature rise energy, is a known quantity. Heating the initial target preheating time with the maximum heating power of the instant heating water dispenser, such as 2000W, according to geometric meaning, the corresponding area is 2000W multiplied by the initial target preheating time, for example, half of the heatable initial target preheating time, namely, the corresponding area s1=2000×0.5t is determined Initial target preheating time The remaining area S2 is then the total area S minus S1, so that the value of M2 can be determined from the remaining area and from the remaining time, i.e. from (S-S1)/(t) Target object -0.5t Initial target preheating time ) The value of M2 can be calculated, for example, the value of M2 is 333W, so that preheating is performed at a high power and then at a low power, and thus the purposes of higher preheating temperature and avoiding splashing can be achieved at the same time.
According to another embodiment of the present invention, the target preheating power is expressed by the following formula:
wherein Q is Target object For the target temperature rise energy, t Target object For target warm-up time, M3 and M4 are target warm-up powers, and M3 > M4, t is the current time, tb is the second time node, tc is the third time node, and a, b, and c are coefficients. Wherein M3 is the maximum preheating power of the instant heating water dispenser, M4, a, b and c are determined according to the residual water target preheating time, namely the target preheating time of the heat pipe, the target preheating time and the target temperature rise energy, tb is determined according to the residual water target preheating time, and tc is determined according to the instant heating pipe target preheating time.
Specifically, in addition to preheating according to the maximum preheating power of the instant heating water dispenser for a period of time, the preheating may be changed directly to low power, or the power may be smoothly reduced during a period of time after the preheating according to the maximum preheating power of the instant heating water dispenser for a period of time, for example, in the above formula, heating is performed by the maximum preheating power M3 of the instant heating water dispenser, the heating time may be determined according to the remaining water target preheating time, for example, half of the heatable remaining water target preheating time, then, during the next period of time, the power control may be performed in the form of a quadratic function, the preheating time may be determined according to the instant heat pipe target preheating time, for example, half of the heatable target preheating time may be heated, and during the final period of time, the preheating may be performed with stable low power, and also according to the geometric meaning of the integral function, the values of coefficients a, b, c of the quadratic function and the target preheating power M4 may be determined according to the remaining water target preheating time, i.e., the heat pipe target preheating time, target preheating time and target temperature rise energy. The form of the quadratic function may be replaced with other functions such as a trigonometric function, etc., so that the preheating power may be smoothly transited to the last lower target preheating power for a while after the maximum preheating power. Therefore, the preheating is performed at high power and then at low power, so that the purposes of high preheating temperature and splashing avoidance are simultaneously realized.
The preheating method of the present invention is described below with reference to fig. 3.
As a specific example, the preheating method of the instant water dispenser of the present invention may include the steps of:
s101, acquiring a first temperature difference value between the target temperature and the residual water temperature in the heat pipe, and determining a residual water target temperature rise value according to the first temperature difference value and a first preset coefficient.
S102, determining the residual water target preheating time according to the residual water target temperature rise value, namely the maximum preheating power of the hot water dispenser, and the specific heat capacity and the total mass of the residual water.

S109, judging whether the target preheating time is reached. If yes, go to step S110; if not, step S108 is performed.
S110, after preheating is finished, water is normally discharged.
